DETAILED DESCRIPTION
[0029] In order that the technical problem solved by the present
invention, the adopted technical solution and the achieved
technical effects are clearer, the technical solution of
embodiments of the present invention is further described in detail
below in combination with a drawing. Apparently, embodiments
described are only part of embodiments of the present invention,
rather than all embodiments. Based on embodiments in the present
invention, all other embodiments obtained by those skilled in the
art on the premise of not doing creative work shall belong to the
protection scope of the present invention.
[0030] Apparatus Embodiment
[0031] As shown in FIG. 1 and FIG. 2, the present application
provides a washing machine, including a closed washing space 2. A
suspension component 4 capable of moving in a first movement manner
and at least one group of nozzles 8 are arranged in the closed
washing space 2. The suspension component 4 is used for suspending
washings, and the nozzles 8 are connected with a water pump. The
water pump is preferably a high-pressure water pump, and sprays a
high-pressure water flow through the nozzles 8 after pressurizing
the water flow to wash washings suspended on the suspension
component 4. The high-pressure water flow can cover at least one
side of area of washings by changing a relative position between
washings and the nozzles. Specifically, washings can move in the
first movement manner along with the suspension component 4; the
high-pressure water flow which flows from the nozzles 8 can change
the flushed position along with the movement of washings in the
first movement manner, so that washings can be thoroughly washed
and bring a good washing effect; and moreover, the washing method
replaces drum turning of a drum washing machine and impeller stir
of an impeller washing machine through flushing with high-pressure
water, so as to reduce abrasion to washings and quantity of washing
water.
[0032] In the present embodiment, the first movement manner may be
horizontal linear movement and curvilinear movement, or may be
rotating movement, helical movement, constant-speed movement or
variable-speed movement.
[0033] Specifically, the washing machine provided in the present
application has a door body and a housing 1; the door body and the
housing 1 form the closed washing space 2; the washing space 2 can
accommodate washings and other apparatuses; and a washing process
is finished in the washing space 2. In the present embodiment, the
washing space 2 formed by the door body and the housing 1 is
sealed, so as to ensure that the high-pressure water flow will not
overflow from the washing space 2 during washing.
[0034] The nozzles 8 are arranged at an upper end of a main spray
pipe 7, and a plurality of nozzles 8 with a small aperture are
uniformly arranged on the main spray pipe 7. The high-pressure
water pump is connected with the main spray pipe 7 through a water
supply pipe 9. Washing water enters the washing space 2 by means of
the control of a water valve. The high-pressure water pump absorbs
the washing water on the bottom of the washing space 2; after
pressurized, the washing water is supplied to the water supply pipe
9 to reach the main spray pipe 7; and the high-pressure water flow
is sprayed through the nozzles 8 on the main spray pipe 7. Since
the high-pressure water flow is sprayed at the nozzles 8 at high
speed and has a strong impact on spots attached to washings, the
spots, sprayed by the water flow, on the surfaces of washings leave
the surfaces of washings along with the water flow. However, if
washings and the nozzles 8 make no relative movement, areas of
washings washed by the high-pressure water flow are only points
corresponding to the nozzles. In the present invention, the
suspension component 4 is designed as a horizontal moving
component. During washing, washings are driven to horizontally move
through the horizontal movement of the suspension component 44. The
high-pressure water flow that flows from the nozzles 8 can change
the flushed position along with the horizontal movement of
washings, so that washings can be thoroughly washed and bring a
good washing effect.
[0035] Preferably, two supporting components 3 with a certain
distance are arranged at an upper end of the housing 1. One end of
the supporting components 3 is fixed on the housing 1, and the
other end is a circular ring. The suspension component 4 includes a
clothes suspending rod 42 and an eccentric apparatus 41 arranged on
the clothes suspending rod 42. Both ends of the clothes suspending
rod 42 respectively penetrate through the circular ring of the
supporting components 3, and can move relative to the circular
ring. The eccentric apparatus 41 includes a base 411 and a rotating
component 413. The base 411 is preferably formed by a circular
bottom plate and a circle of surrounding plates arranged on an edge
of the bottom plate. A sliding groove 412 vertical to the clothes
suspending rod 42 is arranged in a middle part of the base 411. One
end of the rotating component 413 is connected with an output shaft
of the motor, and the other end is a connecting shaft which
penetrates through the sliding groove 412 for fixed connection with
the clothes suspending rod 42. The motor can drive the rotating
component 413 to rotate. At this moment, the connecting shaft of
the rotating component 413 can slide back and forth along the
sliding groove 412, so as to drive the clothes suspending rod 42 to
move horizontally.
[0036] Washings suspended on the clothes suspending rod 42 make
horizontal linear movement by driving the eccentric apparatus 41
through the motor, and the high-pressure water flow that flows from
the nozzles 8 can change the flushed position along with the
horizontal linear movement of washings, so that washings can be
thoroughly washed and bring a good washing effect.
[0037] In the present embodiment, preferably, the washing machine
further includes a nozzle driving apparatus configured to drive the
nozzles 8 to move in the second movement manner in the washing
space 2, and the second movement manner is different from the first
movement manner.
[0038] In the present embodiment, the second movement manner may be
vertical linear movement and curvilinear movement, or may be
rotating movement, helical movement, constant-speed movement or
variable-speed movement and the like.
[0039] In the present embodiment, preferably, the nozzle driving
apparatus drives the nozzles 8 to make vertical movement in the
washing space 2. The nozzle driving apparatus has a structure as
follows: at least one horizontally symmetrical gear rack 5 is
movably arranged on a left and a right side walls of the housing 1
of the washing machine. Each gear rack 5 is matched with one
driving gear 6 and is driven by the driving gear 6. Meanwhile, two
horizontal ends of the main spray pipe 7 are respectively fixedly
installed on the gear racks 5 of two horizontal sides. The driving
gear 6 is connected with another motor, and is driven by the motor
to make rotating movement, so as to drive the gear racks 5 to move
up and down along an inner wall of the housing 1 so that the
nozzles 8 and the main spray pipe 7 can also make vertical
movement. Specifically, when the motor drives the driving gear 6 to
make anticlockwise movement, the driving gear 6 drives the gear
racks 5 to move down along the inner wall of the housing 1, so as
to drive the nozzles 8 and the main spray pipe 7 to make vertical
downward movement, as shown in FIG. 1; and when the motor drives
the driving gear 6 to make clockwise movement, the driving gear 6
drives the gear racks 5 to move up along the inner wall of the
housing 1, so as to drive the nozzles 8 and the main spray pipe 7
to make vertical upward movement, as shown in FIG. 2. Preferably,
the water supply pipe 9 is flexible or telescopic. The flexible or
telescopic water supply pipe 9 can be extended and retracted along
with the upward and downward movement of the main spray pipe 7.
[0040] In the present embodiment, through the relative crossed
movement of washings and the nozzles 8, the high-pressure water
flow that flows from the nozzles 8 can further change the flushed
position of washings along with the vertical movement of the
nozzles 8, so as to achieve that the whole surface area of washings
can be flushed by the high-pressure water flow, so that the washing
effect of washings is better.
[0041] In the present embodiment, a water inlet of the water supply
pipe 9 is positioned in the water on the bottom of the washing
space 2. Since the water absorbed by the high-pressure water pump
is the water accumulated on the bottom of the washing space 2, the
water is recycled. As a preferred solution, a filtering apparatus
is installed on the water supply pipe 9 between the water inlet and
the nozzles 8, so that the water is purified before re-sprayed, so
as to play a better washing effect.
[0042] Method Embodiment
[0043] The present application further provides a washing method.
The washing method is applied to the above washing machine.
Washings are suspended in the washing space through the suspension
component. The washing space is preferably a closed washing space.
During washing, washings move in the first movement manner in the
washing space, simultaneously washings are washed by the water flow
which is sprayed by the nozzles that move in the second movement
manner different from the first movement manner, and the water flow
covers at least part of washings by changing the relative position
between washings and the nozzles.
[0044] As a preferred solution, the first movement manner is that
the suspension component drives washings to make linear or
curvilinear reciprocating movement along a first direction.
[0045] Further preferably, the first direction is a horizontal
direction. Specifically, the motor drives the rotating component to
make clockwise or anticlockwise rotation on the base, and a
connecting column of the rotating component slides back and forth
in the sliding groove, so as to drive the clothes suspending rod to
make horizontal linear movement.
[0046] A group of nozzles is installed in the washing space.
Preferably, the nozzles are arranged on the main spray pipe. The
main spray pipe is communicated with the washing water on the
bottom of the washing space through the water supply pipe, and a
water pump is connected to the water supply pipe between the
washing water on the bottom of the washing space and the nozzles.
The water pump is preferably a high-pressure water pump. During
washing, the high-pressure water pump absorbs the washing water on
the bottom of the washing space; after pressurized, the washing
water reaches the main spray pipe through the water supply pipe;
and the high-pressure water flow is sprayed through the nozzles.
Washings are washed through the high-pressure water flow sprayed by
the nozzles, and the high-pressure water flow can cover at least
one side of area of washings.
[0047] Since washings can make horizontal linear movement along
with the suspension component and the high-pressure water flow
which flows from the nozzles can change the flushed position along
with the horizontal linear movement of washings, washings can be
thoroughly washed and bring a good washing effect; and moreover,
the washing method replaces drum turning of a drum washing machine
and impeller stir of an impeller washing machine through flushing
with the high-pressure water, so as to reduce abrasion to washings
and quantity of washing water.
[0048] In the present embodiment, preferably, the second movement
manner is that the nozzles make linear or curvilinear movement
along a second direction.
[0049] Further preferably, the second direction is a vertical
direction, and the nozzles, driven by the nozzle driving apparatus,
make vertical linear or curvilinear movement.
[0050] Through the relative crossed movement of washings and the
nozzles, the high-pressure water flow that flows from the nozzles
can change the flushed position along with the vertical movement of
the nozzles, so as to achieve that the whole surface area of
washings can be flushed by the high-pressure water flow, so that
the washing effect of washings is better.
[0051] In the present embodiment, as a preferred solution, the
process that the nozzles, driven by the nozzle driving apparatus,
make vertical linear movement is realized through the following
manner: the motor drives the gears on two horizontal sides to
rotate; the gears on both sides respectively drive the gear racks
engaged with the gears to move up and down; the gear racks on both
sides move up and down and then drive the main spray pipe and the
nozzles arranged on the main spray pipe to make vertical linear
movement.
[0052] Of course, the first direction and the second direction are
not limited to the above, and may also be other directions.
Moreover, the first movement manner is not limited to the above,
and may be rotating movement, helical movement, constant-speed
movement or variable-speed movement; and the second movement manner
is also not limited to the above, and may be rotating movement,
helical movement, constant-speed movement or variable-speed
movement and the like.
[0053] It should be noted that, the above contents are only better
embodiments and technical principles applied by the present
invention. Those skilled in the art should understand that the
present invention is not limited to specific embodiments described
herein, and those skilled in the art can make various obvious
changes, readjustments and replacements without departing from the
protection scope of the present invention. Therefore, although the
present invention is described in detail through above embodiments,
the present invention is not limited to above embodiments. The
present invention may include more other equivalent embodiments
without departing from the concept of the present invention, and
the scope of the present invention is determined by the scope of
the claims attached.
