DETAILED DESCRIPTION OF THE EMBODIMENTS
[0033] In order to make the aim, the technical solution and the
advantages of the present disclosure much clear, the present
disclosure is further described in detail with reference to the
accompanying drawings and embodiments. It is evident that the
embodiments are only some exemplary embodiments of the present
disclosure, and the present disclosure is not limited to such
embodiments.
[0034] The main idea of the present disclosure is combining a
cross-flow duct with a centrifugal duct to form a cross-flow
centrifugal duct, such that one conditioner can have two kinds of
air flow modes, and not only has advantages of the cross-flow duct
itself, but also has characteristics of the centrifugal duct, the
advantages of the cross-flow duct itself include high speed, low
pressure, smooth flow, low noise, the characteristics of the
centrifugal duct include large air flow, high pressure, far
distance of air supply, good disturbance effect, meanwhile,
rotatable centrifugal volute further realizes blowing wind from
multi-angles, such that indoor temperature can distribute more
uniformly, and the comfortableness of the conditioner can be
greatly improved.
[0035] The air conditioner can be a split-floor-type air
conditioner and a split wall-mounted type air conditioner. The
split-floor-type air conditioning and the split wall-mounted type
air conditioner are further described in detail.
[0036] Referring to FIGS. 1-5, the split-floor-type air conditioner
according to a first exemplary embodiment of the disclosure is
shown. The split-floor-type air conditioner includes a body, a
cross-flow centrifugal duct configuration located inside the body,
the cross-flow centrifugal duct configuration includes a first
motor 110, a cross-flow turbine 120 and a turbine 310 coaxially
driven by the first motor 110, and a cross-flow volute 130 and a
centrifugal volute 320 located outside of the cross-flow turbine
120 and the turbine 310 respectively. The cross-flow turbine 120
and the cross-flow volute 130 form a cross-flow duct 100, the
turbine 310 and the centrifugal volute 320 form a centrifugal duct
300. A combination of the cross-flow duct 100 and the centrifugal
duct 300 forms the cross-flow centrifugal duct configuration of the
split-floor-type air conditioner. A portion of the body
corresponding the cross-flow duct 100 has a first air inlet frame
component 400 used to supply wind to the cross-flow turbine 120
located inside the cross-flow duct 100, and a first air outlet 500
used to outlet wind passing through the cross-flow turbine 120, the
body has a second air inlet frame component 600 which can supply
wind to the turbine 310 located inside the centrifugal duct 300,
the body further has a second air outlet 700 which can outlet wind
passing through the centrifugal volute 320.
[0037] The cross-flow turbine 120 and the turbine 310 can be driven
to rotate simultaneously by the first motor 110, meanwhile two
different kinds of gas flow modes are existed in the body with the
action of the cross-flow volute 130 and the centrifugal volute 320.
Air flow coming from the first air inlet frame component 400 flows
in along a direction perpendicular to an axis of the cross-flow
turbine 120, that is, the air flow coming from the first air inlet
frame component 400 flows in along a radial direction of impeller
of the cross-flow turbine 120, passes through an inside of the
impeller, and is discharged through another end along the radial
direction, the air flow can flow crossly or flow transversely, and
be discharged through the first air outlet 500 finally, a route of
the air flow is a straight line. The cross-flow turbine 120 has the
features of high speed, low pressure, smooth flow, and low noise,
the conditioner realizes refrigeration effect and heating effect
mainly through the cross-flow turbine 120. However, air flow coming
from the second air inlet frame component 600 passes through
turbine located inside the centrifugal duct 300, and finally is
discharged from the centrifugal volute 320 and the second air
outlet 700. The portion of the air flow has the features of high
speed, high pressure, and has disturbance effect on an air outlet
of the cross-flow turbine 120 to form air convection, such that
indoor temperature can distribute more uniformly, and
comfortableness of the conditioner usage can be improved based on
the realizing of cooling and heating by the cross-flow turbine 120.
Meanwhile, the centrifugal duct 300 is compact, low cost, under a
circumstances that a cross section of the centrifugal duct 300 and
a cross section of a traditional conditioner are the same, it can
be realize by slightly increasing a length.
[0038] In an exemplary embodiment, the turbine 310 can be a
cross-flow turbine, the turbine 310 can be integrated with the
cross-flow turbine 120 through splitting plates 800. At this time,
the turbine 310 can be regarded as a part of the cross-flow turbine
120. The cross-flow turbine 120 includes a plurality of cross-flow
blade groups 121 connected with each other in an end-to-end mode,
adjacent cross-flow blade groups 121 can be connected with each
other through the splitting plates 800. One end of the cross-flow
blade group 121 is connected with the first motor 110, opposite end
of the cross-flow blade group 121 is defined as the turbine 310,
the centrifugal volute 320 can be located at an outside of the
turbine 310, such forming the centrifugal duct 300. Of course, the
turbine 310 can also be a centrifugal turbine, the centrifugal
turbine can be fixed on one end of the cross-flow turbine 120
through the splitting plates 800. No matter the turbine 310 is
centrifugal turbine or cross-flow turbine 120, the centrifugal
volute 320 is arranged at the outside of the turbine 310 to change
flow direction of the air flow, the disturbances effect of the air
outlet of the cross-flow turbine 120 can be realized, so that air
forms convection, the comfortableness of blowing wind can be
improved. When the centrifugal turbine is rotating to produce
centrifugal force with the active of the impeller, a middle portion
forms a negative pressure zone, therefore air flow can be inhaled
into the turbine along the axis, then spread around along the axis,
finally directionally discharged by the centrifugal volute 320.
During the process, the centrifugal turbine has features of large
air flow, high pressure, so disturbance effect is better, that is,
the combination of the centrifugal turbine and the centrifugal
volute 320 is conducive to improving the comfortableness of the
conditioner.
[0039] Referring to FIG. 4, one end of the cross-flow turbine 120
away from the turbine 310 has a sleeve 122, the sleeve 122 is fixed
with an output shaft 111 of the first motor 110, a middle of a
surface of the splitting plate 800 connecting the cross-flow
turbine 120 with the turbine has an axis 810, the surface faces the
turbine 310, the turbine 310 is arranged around the axis 810, the
axis 810 supports the turbine 310. After the first motor 110
starts, the output shaft 111 of the first motor 110 drives the
cross-flow turbine 120 and the turbine 310 to rotate by the sleeve
122. The cross-flow turbine 120 and the turbine 310 can be driven
simultaneously by one motor, therefore the efficiency is high, the
structure is compact, and it is easy to use.
[0040] One end of the turbine 310 can be connected with the
cross-flow turbine 120 by the splitting plate 800, the other end
opposite to the splitting plate 800 has an air inlet 3111, the air
inlet 311 can be connected with the second air inlet frame
component 600 through a bend pipe (not shown). Therefore, air flow
from the second air inlet frame component 600 can flow into the
turbine 310 by passing through the bend pipe, the air inlet 311 in
sequence, and be exhausted by the centrifugal volute 320. As the
bend pipe is located between the air inlet 311 and the second air
inlet frame component 600, such a number of the second air inlet
frame component 600 can be one or multiple, and a location of the
second air inlet frame component 600 can be set flexibly. When the
number of the second air inlet frame component 600 is one, the
second air inlet frame component 600 can be located at a lateral
housing (not shown) of the body or a back housing 900. When the
second air inlet frame component 600 is multiple, the second air
inlet frame components 600 are located on two lateral housings of
the body respectively, or several are located on the lateral
housing of the body, and several are located on the back housing of
the body. The choosing of the number of the second air inlet frame
components 600 can be determined by the performance of the
conditioner, different numbers of the second air inlet frame
components 600 are chosen or different locations are set, it can be
simply achieved by adding the number of the bend pipe or increasing
the length of the bend pipe as required.
[0041] Preferably, in an exemplary embodiment, the body also has a
power component (not shown) located inside the body, the power
component can be used to drive the centrifugal volute 320 to rotate
around the turbine. The power component includes a second motor, a
driving gear fixed with an output shaft of the second motor, and a
driven gear engaged with the driving gear and located at an outside
surface of the centrifugal volute 320. After the second motor
starts, the output shaft of the second motor drives the driving
gear to rotate, the driven gear rotates by engaging with the
driving gear, the centrifugal volute 320 rotates with it. The
centrifugal volute 320 has a volute tongue 321, that is the air
outlet, when the centrifugal volute 320 rotates to different angles
under the driving of the driving gear, the volute tongue 321
regarded as the air outlet is located at a different position, such
the air flow pushed from the turbine 310 along the axis direction
can have different air-out directions, therefore, sweeping wind
within a scope of a certain angle can be achieved.
[0042] Wind from the volute tongue 321 of the centrifugal volute
320 can be exhausted to the outside of the body through the second
air outlet 700. In an exemplary embodiment, the first air outlet
500 is located at a middle part of a front housing 910 of the body,
as the cross-flow turbine 120 is long cage shaped, and vertically
located at a middle part of the body, the first air outlet 500
corresponds to the cross-flow turbine 120, the second air outlet
700 is located at a bottom of the front housing 910 of the
body.

conditioner according to a second exemplary embodiment of the
disclosure. All that differs from the first exemplary embodiment to
the second exemplary embodiment is that, in the second exemplary
embodiment, a centrifugal duct 300 is located on a top of a
cross-flow duct 100. A second air outlet 700 is correspondingly
located on a front housing of a body, that is, located at the top
of a first air outlet 500. The other structures of the second
exemplary embodiment are the same with the first exemplary
embodiment, no need to repeat herein.

radial direction, the air flow can flow crossly or flow
transversely, and be discharged through the first air outlet 500
finally, a route of the air flow is a straight line. The cross-flow
turbine 120 has the features of high speed, low pressure, smooth
flow, and low noise, the conditioner realizes refrigeration effect
and heating effect mainly through the cross-flow turbine 120.
However, air flow coming from the second air inlet frame component
passes through impeller located inside the centrifugal duct 400,
and finally is discharged from the centrifugal volute 420 and the
second air outlet 600. The portion of the air flow has the features
of high speed, high pressure, and make disturbance effect on an air
outlet of the cross-flow turbine 120 to form air convection, such
that air can distribute more uniformly, and comfortableness of the
conditioner usage can be improved based on the realizing of cooling
and heating by the cross-flow turbine 120. Meanwhile, the
centrifugal duct 400 is compact, low cost, under a circumstances
that a cross section of the centrifugal duct 400 and a cross
section of a traditional conditioner are the same, it can be
realize by slightly increasing a length.
[0047] In an exemplary embodiment, two turbines 410 can both be
cross-flow turbines, two turbines 410 can be integrated with
corresponding cross-flow turbines 120 through splitting plates 700.
At this time, the turbine 410 can be regarded as a part of the
cross-flow turbine 120. Each cross-flow turbine 120 includes a
plurality of cross-flow blade groups 121 connected with each other
in an end-to-end mode, adjacent cross-flow blade groups 121 can be
connected with each other through the splitting plates 700. One end
of the cross-flow blade groups 121 is connected with the first
motor 110, opposite end of the cross-flow blade groups 121 is
defined as the turbine, a centrifugal volute 420 is located at an
outside of one turbine, such forming the centrifugal duct 400. Of
course, the turbines can also be centrifugal turbines, the
centrifugal turbines can be fixed on one end of the cross-flow
turbine 120 through the splitting plates 700. No matter the
turbines are centrifugal turbines or cross-flow turbines 120, the
centrifugal volutes 420 are arranged at the outside of the turbines
to change flow direction of the air flow, the disturbances effect
can be applied to the air outlet of the cross-flow turbine 120, so
that air forms convection, the comfortableness of blowing wind can
be improved. When the centrifugal turbines are rotating to produce
centrifugal force with the active of the impeller, middle portions
form a negative pressure zone, therefore air flow can be inhaled
into the turbines along the axis, then spread around along the
axis, finally directionally discharged by the centrifugal volute
420. During the process, the centrifugal turbines have features of
large air flow, high pressure, so disturbance effect is better,
that is, the combination of the centrifugal turbines and the
centrifugal volutes 420 is conducive to improving the
comfortableness of the conditioner.
[0048] Referring to FIG. 8, one end of each cross-flow turbine 120
away from the turbines 410 has a sleeve 122, the sleeves 122 are
fixed with output shafts 111 of the first motor 110, a middle of a
surface of one splitting plate 700 used to connect the cross-flow
turbine 120 with the turbine 410 has an axis 710, the surface faces
the turbine 410, the turbines 410 are arranged around the axes 710,
the axes 710 support the turbines 410. After the first motor 110
starts, the output shafts 111 of the first motor 110 drive the two
cross-flow turbine 120 and the two turbines 410 to rotate by the
sleeves 122. The cross-flow turbines 120 and the turbines 410 can
be driven simultaneously by one motor, therefore the efficiency is
high, the structure is compact, and it is easy to use.
[0049] One end of the turbine 410 can be connected with
corresponding cross-flow turbine 120 by the splitting plates 700,
the other end opposite to the splitting plates 700 has an air inlet
411, the air inlet 411 can be connected with the second air inlet
frame component. Therefore, air flow from the second air inlet
frame component can flow into the turbines 410 by the air inlets
411, and be exhausted by the centrifugal volute 420. In an
exemplary embodiment, a number of the second air inlet frame
component can be two, the second air inlet frame components are
located at a left lateral surface and a right lateral surface of
the body respectively, connected with two air inlets 411
respectively.
[0050] Preferably, in an exemplary embodiment, the body also has
power components (not shown) located inside the body, the power
components can be used to drive the centrifugal volutes 420 to
rotate around the turbine, respectively. Each power component
includes a second motor, a driving gear fixed with an output shaft
of the second motor, and a driven gear engaged with the driving
gear and located at an outside surface of the centrifugal volute
420. After the second motors start, the output shafts of the second
motors drive the driving gears to rotate, the driven gears rotate
by engaging with the driving gears, the centrifugal volutes 420
rotate with them. The centrifugal volutes 420 have volute tongues
421, that are the air outlets, when the centrifugal volutes 420
rotate to different angles under the driving of the driving gears,
the volute tongues 421 regarded as the air outlets are located at a
different position, sweeping wind within a scope of a certain angle
can be achieved.
[0051] Wind from the volute tongues 421 of the centrifugal volutes
420 can be exhausted to the outside of the body through the second
air outlets 600. In an exemplary embodiment, the first air outlet
500 is located at a bottom of the body, as the cross-flow turbines
120 are long cage shaped, the first air outlet 500 corresponds to
the two cross-flow turbine 120, a number of the second air outlet
600 is two, the second air outlets 600 correspond to the two
centrifugal duct 400, and located at a left side and a right side
of the front housing 800 of the body. And, in an exemplary
embodiment, a number of an air deflector can be one, the air
deflector passes through three air outlets of the front housing
800.

electric control box is located at a back of the motor, so that,
the electric control bar located in the motor or the electric
control box 300 can be directly took out from an inferolateral
surface of the body when overhaul the conditioner.
