DETAILED DESCRIPTION
[0046] The embodiments of this application are described in detail
below, and examples of the embodiments are shown in the attached
drawings, throughout which the identical or similar labels are used
to denote the identical or similar elements or elements having
identical or similar functions. The embodiments described below by
reference to the attached drawings are illustrative and are used
only to interpret this application but should not be construed as
limiting this application.
[0047] The following part refers to FIGS. 1-9 to describe the air
conditioner indoor unit 100 according to embodiments of this
application, which can refrigerate and heat indoor air.
[0048] As shown in FIGS. 1 and 5, the air conditioner indoor unit
100 according to embodiments of this application includes housing
1, fan assembly 2, first drive mechanism 4 and first door 3.
[0049] Where, first air inlet 12a, first air outlet 11a, and second
air outlet 11b can be arranged at housing 1, and housing 1 may
contain the air duct flow paths that connect the air inlet 12a to
the first air outlet 11a, and connect the air inlet 12a to the
second air outlet 11b respectively, and the fan assembly 2 may be
placed in the housing 1 to guide the air flow circulating in the
air duct flow path. Specifically, when the air conditioner indoor
unit 100 works, the fan assembly 2 can be rotated to create
negative pressure in the air duct flow path so that the air flow
can enter the air path through the air inlet 12a under the effect
of such negative pressure, and can be discharged through the first
air outlet 11a and the second air outlet 11b after circulating in
the air path. The air flow can be discharged only through the first
air outlet 11a or the second air outlet 11b, or be discharged
through both of them.
[0050] As shown in FIG. 5, in a specific example of this
application, the housing 1 can include the front panel 11 and the
back plate assembly 12 which can snap-fit with each other. The air
inlet 12a having the air-inlet grille 121 can be placed on the back
plate assembly 12. The first air outlet 11a can be installed on the
front panel 11, the air duct flow path connecting the first air
outlet 11a to the air inlet 12a can be installed in the housing 1,
and also can include the heat exchanger 7 which may exchange heat
with the air flow in the air duct flow path. After heat exchange,
the air flow can be discharged through the first air outlet 11a; in
this way, the indoor temperature can be regulated.
[0051] As shown in FIGS. 2-5, the first drive mechanism 4 can be
placed in the housing 1, and can be connected to and drive the
first door 3 to move, so that the first door 3 can be in expose or
covered state; when the first drive mechanism 4 drives the first
door 3 to move outwards relative to the housing 1 (forward as shown
in FIG. 3) to the set position, the first door 3 can be switched to
the open state, at which point the first door 2 can expose the
first air outlet 11a; when the first door 3 is in the closed state,
the first door 3 can cooperate with the housing 1 to cover the
first air outlet 11a.
[0052] Specifically, the first drive mechanism 4 can drive the
first door 3 moving forward and backward to expose or cover the
first air outlet 11a. When the air conditioner indoor unit 100
works, the first drive mechanism 4 can drive the first door 3
forward to the set position, at which point the first door 3 can
expose the first air outlet 11a so that the air flow can be
discharged through the first air outlet 11a. When the air
conditioner indoor unit 100 stops working, the first drive
mechanism 4 can drive the first door 3 backward, and the first door
3 can cooperate with the housing 1 to cover the first air outlet
11a.
[0053] As shown in FIG. 6, the second drive mechanism 6 can be
connected to and drive the second door 5 to slide relative to the
housing 1 to expose or cover the second air outlet 11b. Therefore,
through the above setting, the air conditioner indoor unit 100 can
discharge the air through the first air outlet 11a and the second
air outlet 11b simultaneously, so as to improve the air outlet
efficiency of the air conditioner indoor unit 100 and expand the
air supply area of the same. In addition, the air flow blown out
from the first air outlet 11a can be distributed along the
circumferential direction of the first access 3, the air flow from
the first air outlet 11a can collide with the air flow from the
second air outlet 11b in the indoor space, which can play the role
of mixing the flows, make the indoor temperature distribution more
uniform, and realize the air outlet effect without feeling the
air.
[0054] Optionally, the working statuses of the first door 3 and the
second door 5 can be controlled separately. When the air needs to
be discharged through the first air outlet 11a, the first door 3
can be driven by the first drive mechanism 4 so as to switch the
first door 3 to the open state, at which point the first air outlet
11a will be exposed. When the air needs to be discharged through
the second air outlet 11b, the second door 5 can be driven by the
second drive mechanism 6 to slide relative to the housing 1 to
expose the second air outlet 11b. Of course, it can be understood
that the first door 3 and the second door 5 can also move jointly,
that is, the first door 3 and the second door 5 can move
simultaneously, so that the first air outlet 11a and the second air
outlet 11b can be exposed or covered simultaneously.
[0055] Therefore, through the above settings, the first drive
mechanism 4 can realize the exposing and covering of the first air
outlet 11a by controlling the forward and backward movement of
first door 3, while the second drive mechanism 6 can drive the
second door 5 to slide relative to the housing 1 to realize the
exposing and covering of second air outlet 11b, which improves the
sense of science and technology of the air conditioner indoor unit
100. In addition, the air flow blown out from the first air outlet
11a can be distributed along the circumferential direction of the
first door 3, the air flows blown out from the first air outlet 11a
and the second air outlet 11b can be mixed in the indoor space, so
that the air flows can be circulated uniformly to each corner of
the indoor space, and the indoor temperature will be more even.
Furthermore, the first door 3 can prevent the air flow from blowing
directly to the users in the room to avoid discomfort, which
enhances the use comfort of the air conditioner indoor unit 100
significantly.
[0056] According to embodiments of this application, the air
conditioner indoor unit 100 includes the first door 3 and the
second door 5, so that the first drive mechanism 4 can realize the
exposing and covering of the first air outlet 11a by controlling
the forward and backward movement of first door 3, while the second
drive mechanism 6 can drive the second door 5 to slide relative to
the housing 1 to realize the exposing and covering of second air
outlet 11b, which improves the sense of science and technology of
the air conditioner indoor unit 100. In addition, the air flows
blown out from the first air outlet 11a and the second air outlet
11b can be mixed in the indoor space, so that the air flows can be
circulated uniformly to each corner of the indoor space, and the
indoor temperature will be more even, which enhances the use
comfort of the air conditioner indoor unit 100 significantly.
[0057] As shown in FIG. 5, according to some embodiments of this
application, the first door 3 can include the flow guiding member
31 and the sealing member 32. Flow guiding member 31 can be
connected to and driven by the first drive mechanism 4. When first
door 3 is in the open state, the outer wall of the flow guiding
member 31 can guide the air flow to move, and the sealing member 32
can be connected to the flow guiding member 31; when the first door
3 is in the closed state, the sealing member 32 can cooperate with
the housing 1 to cover the first air outlet 11a; it thus can make
the design of first door 3 simpler and improve the air guide effect
of first door 3.
[0058] Specifically, when the first door 3 is in the open state,
the air outlet area of first air outlet 11a can be formed between
the flow guiding member 31 and the housing 1. The air flow can be
blown out along the outer wall of flow guiding member 31. The flow
guiding member 31 can serve to guide air flow, which not only can
reduce the circulation resistance of the air flow, improve the air
outlet efficient of the first air outlet 11a, but also can
distribute the air properly. The air flow can be distributed around
the circumferential direction of flow guiding member 31, so that
the indoor temperature distribution will be more uniform.
[0059] When the first door 3 is in the closed state, the sealing
member 32 can cooperate with the housing 1 to seal the first air
outlet 11a, so as to protect the air conditioner indoor unit 100
and prevent the dust and dirt from entering air conditioner indoor
unit 100 through the first air outlet 11a. Optionally, the first
air outlet 11a can be formed to have a circular shape, and the
sealing member 32 can be formed to have a disk shape. The outer
diameter of the sealing member 32 can be larger than the diameter
of the first air outlet 11a, so as to improve the sealing effect of
first air outlet 11a. Optionally, the sealing member 32 may be
either integrated with the flow guiding member 31, or connected to
the guiding member 31 by screw fastening or riveting.
[0060] As shown in FIG. 4 and FIG. 8, in some embodiments of this
application, the vertical sectional area of the flow guiding member
31 increases gradually along the direction from the air inlet 12a
to the first air outlet 11a (from rear to front as shown in FIG.
8), which improves the air guide effect of flow guiding member 31
and prevents the air flow from being blown forward to the user who
may thus feel uncomfortable.
[0061] For example, as shown in FIG. 8, the flow guiding member 31
may include the mounting part 311 and the air guide part 312 which
can be connected in sequential order from the rear to the front,
and the mounting part 311 can slide-fit with the housing 1. The
mounting part 311 is formed to be cylindrical while the air guide
part 312 is formed to be truncated cone shaped. The vertical
sectional area of air guide part 312 increases gradually from the
rear to the front, such that the air guide part 312 is
approximately horn-shaped. Therefore, when the air flows out
through the first air outlet 11a, the air flow can be dispersed
along the outer wall of the air guide part 312 around the first air
outlet 11a, which can result in a good air dispersion effect.
Optionally, the air guide part 312 can include several studs 312a
spaced in its circumferential direction on the front end, and the
sealing member 32 can be bolted to the air guide part 312.
[0062] As shown in FIG. 9, in some embodiments of this application,
the sealing member 32 can include multiple first micro air outlets
32a distributed at intervals. Each first micro air outlet 32a can
run through the sealing member 32 in the thickness direction
(front-rear direction as shown in FIG. 9); the flow guiding member
31 can include an air guide channel connected to multiple first
micro air outlets 32a, which thereby can realize the breezeless air
outlet effect and greatly improve users' comfort level.
[0063] Specifically, the air conditioner indoor unit 100 can have
the first normal air supply mode and the first breezeless mode.
When the air conditioner indoor unit 100 is in the first normal air
supply mode, the first door 3 will be in the open state, and can be
driven by the first drive mechanism 4 to move forward to the set
position to expose the first air outlet 11a so that a part of the
air can be dispersed around the flow guiding member 31 to the first
air outlet 11a, while another part of the air can flow into the air
guide channel and be discharged through multiple first micro air
outlets 32a. When the air conditioner indoor unit 100 is in the
first breezeless mode, the first door 3 will be in the closed
state, and the air can flow into the air guide channel and be
discharged through multiple first micro air outlets 32a. It could
be understood that multiple first micro air outlets 32a can divide
the air flow into several small branch air flows, and the first
micro air outlets 32a with a small diameter can slow down the air
flow, so that the air can flow out slowly through multiple micro
air outlets. It thus can realize the breezeless air supply effect,
prevent the air from being blown directly to the users, thus
causing discomfort, and make the indoor temperature distribution
more uniform, which improves the user experience significantly.
[0064] Optionally, when the air conditioner indoor unit 100 is in
the cooling mode, it can be adjusted to the first breezeless mode
to prevent the cool air from being blown directly to indoor users,
and the cool air can be circulated to the indoor space slowly
through multiple first micro air outlets 32a. When the air
conditioner indoor unit 100 is in the heating mode, it can be
adjusted to the first normal air supply mode since the air density
of the warm air is relatively small and the circulation speed is
relatively slow, so that the warm air can be circulated quickly
into the indoor space through the first air outlet 11a, thereby
improving the heating efficiency of the air conditioner indoor unit
100.
[0065] As shown in FIG. 6, according to some embodiments of this
application, the first drive mechanism 4 can include the first
drive motor 45, the first drive gear 41 and the first rack 42,
where the first drive motor 45 can be mounted in the housing 1, the
first drive gear 41 can be connected to and driven by the first
drive motor 45 to rotate, the first rack 42 can extend along the
moving direction of first door 3 (front-rear direction as shown in
FIG. 6) and mesh with and be driven by the first drive gear 41, and
one end of the first rack 42 can be connected to and drive the
first door 3 to move. Therefore, the above settings can make the
design of first drive mechanism 4 simpler; the first drive
mechanism 4 drives the first door 3 by meshing the gear with the
rack, which can make the operation of first door 3 more stable and
reduce the working noise of air conditioner indoor unit 100.
[0066] Optionally, the first drive mechanism 4 can include two
one-to-one matching pairs of first drive gear 41 and first rack 42,
which can be spaced and connected to the first door 3 respectively,
and which thus makes the matching structure between the first drive
mechanism 4 and the first door 3 firmer, and the operation of the
first door 3 more stable. Further, the first drive mechanism 4 can
include a first drive motor 45, the first drive motor 45 is a
two-axle motor, two shafts of which rotate in the same direction
and are connected to the first drive gears 41, respectively. Thus,
the above settings can make the overall structure of the first
drive mechanism 4 more compact and also improve the operational
uniformity of the two first racks 42. Of course, the first drive
mechanism 4 can also include two first drive motors 45 that can
operate synchronously, and each of the drive motors 45 is a
single-axle motor and is connected to the corresponding first drive
gear 41.
[0067] In the examples shown in FIG. 6 and FIG. 8, the first door 3
can also include the first connection bracket 33 and the second
connection bracket 34 which are mounted respectively on flow
guiding member 31 and distributed at intervals in the
circumferential direction of flow guiding member 31. The first
connection bracket 33 includes the first mounting hole 331 while
the second connection bracket 34 includes the second mounting hole
341. The first drive mechanism 4 includes two one-to-one matching
pairs of first drive gear 41 and first rack 42, as well as a first
drive motor 45, which is a two-axle motor and whose two motor
shafts rotate in the same direction and are connected to one of the
first drive gear 41 keys respectively. Each first rack 42 includes
a fitting column 422. When the first drive mechanism 4 and the
first door 3 are assembled together, the fitting column 422 of one
first rack 42 can be inserted into the first mounting hole 331 of
the first connection bracket 33, while the fitting column 422 on
the other first rack 42 can be inserted into the second mounting
hole 341 on the second connection bracket 34. Therefore, the above
settings can make the connection structure between the first drive
mechanism 4 and the first door 3 simpler and improve the assembly
efficiency of air conditioner indoor unit 100 greatly.
[0068] It should be noted that the first drive mechanism 4 is not
limited to this design, as long as it can drive the first door 3
forward and backward. For example, the first drive mechanism 4 can
also be a linear motor or hydraulic drive cylinder. One end of the
linear motor or hydraulic drive cylinder can be connected to the
housing 1, and the other end can be connected to the first door 3,
which can also drive the first door 3 to switch flexibly between
the open state and the closed state.
[0069] As shown in FIG. 6 and FIG. 7, in some embodiments of this
application, the first rack 42 can include the limiting groove 421
extending in the moving direction of the first door 3 (front-rear
direction as shown in FIGS. 6-7), the first drive mechanism 4 also
may include the stop lever 43 stretched into the limiting groove
421, the stop lever 43 may slide-fit with the limiting groove 421;
when the first door 3 is in the open state, the stop lever 43 can
push against one end of the limiting groove 421 to limit the first
door 3; so, through the above settings, the stop lever 43 can limit
the position of the first rack 42, make the first door 3 move
accurately to the set position and improve the operational
stability of the air conditioner indoor unit 100.
[0070] Optionally, the contact sensor (not shown in the figure) can
be mounted on the outer wall of the stop lever 43, and can be
connected to communicate with the first drive motor 45. When the
first drive mechanism 4 drives the first door 3 to move, the first
drive motor 45 can drive the first drive gear 41 to rotate, and the
first drive gear 41 meshes with and drives the first rack 42 to
move; when the first rack 42 is moving, the stop lever 43 may
slide-fit with the limiting groove 421 on the first rack 42. When
the first rack 42 moves to the set position, the contact sensor on
the stop lever 43 will contact with one end of the limiting groove
421, and transfer the contact signal to the first drive motor 45
that will stop working after receiving such signal. Therefore, the
intelligent control of the first drive mechanism 4 can be achieved
through the above settings, making the operation of the first drive
mechanism 4 more convenient.
[0071] As shown in FIG. 6, in some embodiments of this application,
the fan assembly 2 may include an air outlet duct member 26 which
can be mounted facing directly with the first air outlet 11a and
have the mounting space 26a in which the first drive mechanism 4
can be mounted. In this way, the fitting structure between the
first drive mechanism 4 and the fan assembly 2 would become more
compact and the assembly space in the air conditioner indoor unit
100 can be reduced.
[0072] For example, as shown in FIG. 6, the air outlet duct member
26 can be formed in a circular loop and includes a mounting space
26a internally, in which the first drive mechanism 4 can be
mounted. The air outlet duct member 26 can also include multiple
air outlet louvers 261 which are mounted around the mounting space
26a and spaced on the circumferential direction of the air outlet
duct member 26, and can serve to guide the air flow and change the
air outlet direction. The mounting space 26a can be either
connected to the air duct flow path or isolated from the same. When
the sealing member 32 is provided with the first micro air outlet
32a, the mounting space 26a can be connected to the air duct flow
path in which the air can flow into the mounting space 26a and be
discharged through the first micro air outlet 32a. When the
mounting space 26a is isolated from the air duct flow path, the air
can enter the indoor space through the air outlet area formed
between the flow guiding member 31 and the housing 1.
[0073] As shown in FIG. 7, in some embodiments of this application,
the first drive mechanism 4 can also include the rack box 44 that
can be connected to the air outlet duct member 26, and can include
the guide hole 441 through which the first rack 42 can pass and
reciprocate relative to the rack box 44. The guide hole 441 can
guide the first rack 42 and make the operation of the same more
regular and stable, thus improving the operation stability of first
door 3.
[0074] According to some embodiments of this application as shown
in FIGS. 1-2, the housing 1 can be provided with the second air
outlet 11b, while the air conditioner indoor unit 100 can be fitted
with the second door 5 and the second drive mechanism 6.
[0075] As shown in FIG. 1, in some embodiments of this application,
the first air outlet 11a and the second air outlet 11b can be
distributed at intervals in the vertical direction, and the first
air outlet 11a is above the second air outlet 11b. The first door 3
is mounted at the first air outlet 11a, and can be connected to the
first drive mechanism 4 which drives the first door 3 to
reciprocate to expose or cover the first air outlet 11a. The second
door 5 is set at second air outlet 11b, and can be connected to the
second drive mechanism 6 which drives the second door 5 to
reciprocate to expose or cover the second air outlet 11b.
[0076] In this case, the open and closed states of the first door 3
and the second door 5 can be controlled respectively. When the air
conditioner indoor unit 100 is in cooling mode, the second drive
mechanism 6 can drive the second door 5 to slide to cover the
second air outlet 11b, while the first drive mechanism 4 can drive
the first door 3 to move forward to expose the first air outlet
11a. It could be understood that the cool air can enter the upper
half of the indoor space through the first air outlet 11a since the
first air outlet 11a is above the second air outlet 11b; the cool
air can circulate slowly from top to bottom in the indoor space as
the cool air density is relatively big, which not only improves the
cooling effect, but also prevents the cool air from being blown to
the indoor users directly through the second air outlet 11b,
resulting in discomfort.
[0077] When the air conditioner indoor unit 100 is in the heating
mode, the second drive mechanism 6 can drive the second door 5 to
slide to expose the second air outlet 11b, while the first drive
mechanism 4 can drive the first door 3 to move forward to expose
the first air outlet 11a. Now the first air outlet 11a and the
second air outlet 11b output air simultaneously. It could be
understood that the heating efficiency of the air conditioner
indoor unit 100 may be enhanced, and the warm air can circulate
smoothly to the floor and warm the feet, which improves the use
experience of the user when the first air outlet 11a and the second
air outlet 11b output the air at the same time as the warm air
density is relatively small and its circulation speed is relatively
low.
[0078] It is noted that the first air outlet 11a and second air
outlet 11b of the air conditioner indoor unit 100 are not limited
to this setting. For example, multiple first air outlets 11a and
multiple second air outlets 11b can be set on the air conditioner
indoor unit 100, which can be set according to the actual use
demand. There is no specific restriction in this application.
[0079] In a specific example of this application, the second air
outlet 11b is located above the first air outlet 11a, where at the
first air outlet 11a there is a first door 3 which can be connected
to the first drive mechanism 4; the first drive mechanism 4 can
drive the first door 3 to reciprocate to expose or cover the first
air outlet 11a. The second door 5 is set at the second air outlet
11b, and can be connected to the second drive mechanism 6 which
drives the second door 5 to reciprocate to expose or cover the
second air outlet 11b. In this case, the second door 5 can expose
the second air outlet 11b by sliding from top to bottom, and cover
the second air outlet 11b by sliding from bottom to top, or cover
the second air outlet 11b by sliding from top to bottom and expose
the second air outlet 11b by sliding from bottom to top.
[0080] In some embodiments of this application, the second drive
mechanism 6 can drive the second door 5 to slide in the up-down
direction, so that the air outlet area of the second air outlet 11b
can be adjusted conveniently. It could be understood that the
second air outlet 11b can be extended in the up-down direction, and
the air outlet area of second air outlet 11b can be adjusted by
controlling the sliding displacement of second door 5 in the
up-down direction, which makes the operation more convenient when
the height of air conditioner indoor unit 100 is relatively large.
Of course, the second drive mechanism 6 can also drive the second
door 5 to slide along the left-right direction and along a
direction that has a tilt angle with respect to the left-right
direction and the up-down direction. The settings can be selected
according to the actual use needs, for which there is no specific
restriction in this application.
[0081] As shown in FIG. 5, in some embodiments of this application,
the second drive mechanism 6 can include a second drive motor (not
shown in the figure), a second drive gear 61 and a second rack 62,
where the second drive gear 61 can be connected to and driven by
the second drive motor to rotate; the second rack 62 can be
extended along the moving direction of second door 5 (up-down
direction shown in FIG. 5); the second rack 62 can mesh with and be
driven by the second drive gear 61; one end of the second rack 62
can be connected to and drive the second door 5 to move; in this
case, the above settings can make the design of the second drive
mechanism 6 simpler. Moreover, the second door 5 is driven by the
second drive mechanism 6 through the gear-rack structure, making
the operation of the second door 5 more stable.
[0082] Optionally, the second drive mechanism 6 can include two
one-to-one matching pairs of second drive motor, second drive gear
61 and second rack 62. Both second racks 62 are extended in the
up-down direction and are spaced in the left-right direction. Both
second racks 62 are connected to the inner walls of second door 5.
When the second drive mechanism 6 works, two second drive motors
rotate synchronously and two second racks 62 drive the second door
5 to slide relative to the housing 1, thereby making the operation
of the second door 5 more stable.
[0083] In a specific example of this application, the air
conditioner indoor unit 100 can also include the door mount plate 8
on which the second drive mechanism 6 can be mounted. In this case,
the second rack 62 can be mounted on the front wall of the door
mount plate 8 and attached to the inner wall of the second door 5.
The door mount plate 8 includes the slide track (not shown in the
figure) while the second door 5 slide-fits with the slide track.
Therefore, the above settings can facilitate the installation and
fixation of the second drive mechanism 6, and besides, the second
door 5 can cooperate with the slide track to reduce the sliding
resistance of the second door 5, thus making its operation smoother
and reducing the working load of the second drive motor.
[0084] It should be noted that this is not the only structural
design of the second drive mechanism 6, as long as it can drive
second door 5 to slide relative to the housing 1. For example, the
second drive mechanism 6 can also be a linear motor or hydraulic
drive cylinder, one end of which can be connected to the housing 1
and the other end can be connected to the second door 5, which can
also drive the second door 5 to slide relative to the housing
1.
[0085] As shown in FIG. 5, in some embodiments of this application,
the fan assembly 2 can include the first fan 22 and the second fan
23, where the first fan 22 can be set in alignment with the first
air outlet 11a, and second fan 23 can be set in alignment with
second air outlet 11b, so that the working states of the first fan
22 and second fan 23 can be controlled separately according to the
use requirements, thereby enhancing the use flexibility of the
user.
[0086] Optionally, the first fan 22 can be an axial fan, a diagonal
fan or a counter-rotating fan. Optionally, the second fan 23 can be
an axial fan, a diagonal fan or a counter-rotating fan.
[0087] In some embodiments of this application, the first fan 22
can be a diagonal fan, and the second fan 23 can be a
counter-rotating fan, which improves the air supply effect of the
air conditioner indoor unit 100. Understandably, the diagonal fan
adopts the mode of axial air inlet and air outlet inclined at a
certain angle along the axial direction for air supply. Moreover,
the air outlet volume of the diagonal fan is relatively large,
which not only improves the air outlet volume of first fan 22, but
also increases the air outlet angle of first fan 22, thereby
expanding the air supply range of the first fan 22.
[0088] This counter-rotating fan can include two wind wheels
mounted on the opposite sides, whose blades are distributed in the
opposite directions. When the counter-rotating fan is working, if
two wind wheels rotate in opposite directions, the air supply
speeds of two wind wheels can be cancelled out in the tangential
directions of their rotation directions, while the air supply
speeds of two wind wheels can overlap in the axial directions,
which can increase the axial air supply speed of the second fan 23,
extend the air supply distance of the second fan 23 and enable the
second fan 23 to supply air for long distance. If two wind wheels
of the counter-rotating fan rotate in the same direction, the air
supply speeds of two wind wheels may overlap in the tangential
direction of their rotation directions, and the air supply speeds
of two wind wheels can be cancelled out in the axial direction, so
that the air can be dispersed all around the second fan 23 and be
prevented from being blown directly to the indoor user through the
second air outlet 11b, thereby realizing breezeless air outlet
effect and improving the use comfort of the user.
[0089] In this case, when only one wind wheel is working, the
counter-rotating fan can be used to realize breezeless air outlet
effect. Specifically, when one wind wheel of the counter-rotating
fans is rotating, another inactive wind wheel also can rotate under
the effect of the air flow. At this time, the two wind wheels will
rotate in the same direction; according to the above description,
the counter-rotating fan also can realize breezeless effect at this
moment.
[0090] Besides, when two wind wheels in the counter-rotating fan
rotate simultaneously at low speed, they can realize the breezeless
air outlet effect regardless of their rotation directions. It could
be understood that the air can flow out slowly through the first
air outlet 11a, thus realizing breezeless effect since two wind
wheels in counter-rotating fan rotate at low speed, and the
circulation speed of air is relatively low.
[0091] Therefore, through the above settings, the first fan 22 can
be turned on when the air supply angle needs to be increased. The
first fan 22 can achieve the effect of air supply in a wide range.
When it is required to supply air for long distance, the second fan
23 can be turned on and the two wind wheels of second fan 23 can be
controlled to rotate in the opposite directions, thus improving the
air supply distance of second fan 23 greatly. When the breezeless
mode is required, two wind wheels of the second fan 23 can be
controlled to rotate in the same direction, so that the second fan
23 can disperse the air all around, preventing the air from being
blown directly to the indoor users through the second air outlet
11b. When the first fan 22 and the second fan 23 work at the same
time, two air flows from the first air outlet 11a and the second
air outlet 11b may be mixed in the indoor room so that the indoor
temperature distribution will be more uniform since the air outlet
angles of the first air outlet 11a and the second air outlet 11b
are different.
[0092] It should be noted that the designs of the first fan 22 and
the second fan 23 are not limited herein. The first fan 22 may be
an axial fan, diagonal fan or counter-rotating fan, and the second
fan 23 also may be an axial fan, diagonal fan or counter-rotating
fan. It can be used in combination according to the actual use
requirements, and there is no specific restriction in this
application.
[0093] In the specific example shown in FIG. 5, the air conditioner
indoor unit 100 can also include the air outlet frame component 21,
which can be connected to the housing 1. The air outlet frame
component 21 has the first air duct member 24 and the second air
outlet part 25 which are distributed at intervals in the up-down
direction. The first air duct member 24 is set in alignment with
the first air outlet 11a, while the second air duct member 25 is
set in alignment with the second air outlet 11b. The first fan 22
is installed in the first air duct member 24, while the second fan
23 is installed in the second air duct member 25. In this case,
through the above settings, not only the first fan 22 and the
second fan 23 can be installed and fixed conveniently, but also the
first air duct member 24 and the second air duct member 25 can be
used to guide the air flow, improving the air supply efficiency of
the air conditioner indoor unit 100.
[0094] As shown in FIG. 9, in some embodiments of this application,
the second door 5 can include multiple second micro air outlets 5a
distributed at intervals. Each second micro air outlet 5a can run
through the second door 5 in the thickness direction (front-rear
direction as shown in FIG. 9), which thereby can realize the
breezeless air outlet effect and greatly improve users' comfort
level.
[0095] Specifically, the air conditioner indoor unit 100 can have
the second normal air supply mode and the second breezeless mode.
When the air conditioner indoor unit 100 is in the second normal
air supply mode, the second drive mechanism 6 can drive the second
door 5 to slide relative to the housing 1 to expose the second air
outlet 11b, through which the air can be discharged. When the air
conditioner indoor unit 100 is in the second breezeless mode, the
second door 5 can cooperate with the housing 1 to cover the second
air outlet 11b, so that the air can be discharged through multiple
second micro air outlets 5a. It could be understood that multiple
second micro air outlet 5a can divide the air flow into several
small branch air flows, and the second micro air outlet 5a with
small diameter can slow down the air flow, so that the air can flow
out slowly through the second micro air outlet 5a. It thus can
realize the breezeless air supply effect, and prevent the air from
being blown directly to the users, causing discomfort, which
improves the user experience significantly.
[0096] Optionally, when the air conditioner indoor unit 100 is in
the cooling mode, it can be adjusted to the second breezeless mode
to prevent the cool air from being blown directly to indoor users,
and the cool air can be circulated to the indoor space slowly
through multiple second micro air outlets 5a. When the air
conditioner indoor unit 100 is in the heating mode, it can be
adjusted to the second normal air supply mode since the air density
of the warm air is relatively small and the circulation speed is
relatively slow, so that the warm air can be circulated quickly
into the indoor space through the second air outlet 11b, improving
the heating efficiency of the air conditioner indoor unit 100.
[0097] As shown in FIG. 9, in some embodiments of this application,
multiple third micro air outlets 11c, which are distributed at
intervals along the periphery of second air outlet 11b, can be
installed on the housing 1, and each third micro air outlet 11c can
run through the housing 1 in the thickness direction (front-rear
direction as shown in FIG. 9). Each third micro air outlet 11c can
be connected to the air duct flow path, increasing air conditioner
indoor unit 100's air supply efficiency and enhancing the air
conditioner indoor unit 100's cooling and heating in the second
breezeless mode.
[0098] For example, as shown in FIG. 9, the second air outlet 11b
can be formed into a circle and multiple second micro air outlets
5a can be distributed on the second door 5 at intervals, placed on
the opposite direction of the second air outlet 11b. Multiple third
micro air outlets 11c, which are located at the periphery of second
air outlet 11b, are placed at intervals on the housing 1, and are
roughly formed into a circle. Therefore, through the above
settings, the third micro air outlets 11c on the second door 5 and
the third micro air outlets 11c on the housing 1 can discharge air
simultaneously, which greatly improves the air outlet efficiency of
air conditioner indoor unit 100, and makes the appearance of air
conditioner indoor unit 100 more artistic.
[0099] The air conditioner according to embodiments of this
application includes the air conditioner indoor unit 100 in the
aforesaid embodiment of this application.
[0100] In the air conditioner according to embodiments of this
application, by setting the air conditioner indoor unit 100
mentioned above, not only the air conditioner's sense of science
and technology can be improved, but also the cooling and heating
effect of air conditioner can be enhanced, which promotes the
user's comfort greatly, and thus enhances the market
competitiveness of air conditioner.
