For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0042] like Figure 1-4 As shown, the household cleaning device of this embodiment includes a washing drum 200, which is used to hold utensils to be cleaned. A mounting groove 100 is provided at the bottom of the washing drum 200, and a flushing component is installed in the mounting groove 100; the flushing component inputs cleaning water into the washing drum 200 to flush the utensils to be cleaned, and the washing water after flushing is output to the outside from the bottom of the washing drum 200.

[0043] The flushing assembly includes a water pump 300 and a fluid conversion device 400 connected to the water pump 300; the water pump 300 transports fluids in different pipelines to the washing tub 200 through the fluid conversion device 400, or discharges the fluid in the washing tub 200 to the outside through the fluid conversion device 400.

[0044] Specifically, the fluid conversion device 400 includes a driving unit 430, a rotating cavity 420 and a fixed shell 410. The rotating cavity 420 can be rotatably installed in the fixed shell 410 under the action of the driving unit 430. A plurality of connecting holes are formed on the rotating cavity 420, and a plurality of connecting pipes are formed on the fixed shell 410. The driving unit 430 drives the rotating cavity 420 to rotate to different angles, so that different connecting holes on the rotating cavity 420 can be connected with different connecting pipes on the fixed shell 410, thereby realizing different water inlet, drainage or drying functions.

[0045] A water outlet 423 is formed above the rotating cavity 420, and a spray arm 800 is connected above the water outlet 423. The washing water in the rotating cavity 420 is output from the spray arm 800 to the washing tub 200 through the water outlet 423 to rinse the utensils to be cleaned in the washing tub 200.

[0046] In some embodiments of the present application, a first water inlet pipe 414 and a drain pipe 413 are connected to the fixed shell 410, a first through hole 421 and a second through hole 422 are formed on the rotating cavity 420, the first water inlet pipe 414 is used to flush the washed device in the washing drum 200 through the rotating cavity 420, and the drain pipe 413 is used to discharge the residual liquid in the rotating cavity 420.

[0047] The position angle between the first water inlet pipe 414 and the drain pipe 413 is 30 degrees to 180 degrees, and the position angle between the first through hole 421 and the second through hole 422 is equal to the position angle between the first water inlet pipe 414 and the drain pipe 413 .

[0048] For example: the first through hole 421 and the second through hole 422 are formed on the surface of the rotating cavity 420 and are located on the same circumference. The angle between the first through hole 421 and the second through hole 422 is designed to be 90 degrees; correspondingly, the angle between the first water inlet pipe 414 and the drain pipe 413 located on the fixed shell 410 is also 90 degrees.

[0049] The first water inlet pipe 414 and the drain pipe 413 are also located on the same circumferential surface and have the same height as the first through hole 421 and the second through hole 422, ensuring that after being rotated to the corresponding angle, the first through hole 421 and the second through hole 422 are connected to the first water inlet pipe 414 and the drain pipe 413.

[0050] When in the washing stage, the first water inlet pipe 414 is connected to the second through hole 422 . At this time, the second through hole 422 is closed by the outer wall of the fixed shell 410 , and the drain pipe 413 is also closed by the fixed shell 410 .

[0051] When in the drainage stage, the drainage pipe 413 is connected to the second through hole 422 , and at this time, the first through hole 421 is connected to the first water inlet pipe 414 to discharge the residual water in the rotating cavity 420 and the first water inlet pipe 414 .

[0052] In some embodiments of the present application, a low water level drain pipe 412 is also provided on the fixed shell, and the position angle of the low water level drain pipe 412 and the drain pipe 413 is the same as the position angle between the first through hole 421 and the second through hole 422, and the low water level drain pipe 412 is connected to the shell of the water pump 300.

[0053] When it is necessary to drain the residual water in the water pump 300 housing, the first through hole 421 is connected to the drain pipe 413 and is in the drainage stage. At this time, the low water level drain pipe 412 is connected to the second through hole 422. While draining, the residual washing water in the water pump 300 housing is drained.

[0054] In other embodiments, an air duct 411 is further provided above the low water level drain pipe 412 , and the outside of the air duct 411 is connected to the fan 700 . In the working state, the air duct 411 and the low water level drain pipe 412 are simultaneously connected to the rotating cavity 420 .

[0055] When the low water level drain pipe 412 is connected to the second through hole 422, the air duct 411 is also connected to the second through hole 422, the fan 700 is running, and the dry gas enters into the conversion wall through the air duct 411, and is then transported to the washing drum 200 to dry the cleaned utensils after washing.

[0056] When the angle between the first through hole 421 and the second through hole 422 is designed to be 90 degrees; the angle between the first water inlet pipe 414 and the drain pipe 413 is also 90 degrees, the distance between the low water level drain pipe 412 and the air duct 411 and the drain pipe 413 is also 90 degrees, ensuring that when the drain pipe 413 is connected to the first through hole 421, the air duct 411 and the low water level drain pipe 412 can be connected to the second through hole 422.

[0057] In order to reuse the washing water, a water collector is also provided in the installation groove 100. The water collector is located below the washing tub 200. The washing water after rinsing the utensils to be cleaned flows back into the water collector and is reused after being filtered.

[0058] Specifically, a water collecting tank 500 and a water return port are formed in the water collector. The water collecting tank 500 opens upward and is a structure that is recessed downward from the bottom of the washing drum 200 to facilitate the collection of washing water. A water return pipe 510 is connected below the water return port. The water return pipe 510 is connected to the fixed shell 410, and the washing water is further introduced into the rotating cavity 420 through the connecting hole located on the rotating cavity 420.

[0059] The end of the return pipe 510 is connected to the water pump 300, connected to the first water inlet pipe 414 through the water pump 300, and then connected to the fixed shell 410. The water in the water collection tank 500 enters the rotating cavity 420 through the return pipe 510, the water pump 300 and the first water inlet pipe 414.

[0060] The water pump 300 integrates the functions of water intake, drainage and water return, which reduces the design of the water pump 300, saves costs, has a high degree of integration, and also reduces problems such as complex crisscrossing of pipelines caused by direct connection of pipelines.

[0061] The flushing device also includes a second water inlet pipe 610, which is used to directly take in water from the outside. The water from the outside and the return water in the water collecting tank 500 are continuously input into the rotating cavity 420 for continuous flushing.

[0062] The second water inlet pipe 610 is in communication with the water collecting tank 500 , and is externally connected to the water inlet pump 600 , so as to transport external washing water into the rotating cavity 420 through the return pipe 510 , the water pump 300 and the first water inlet pipe 414 .

[0063] The driving part 430 includes a driving motor 431 , a driving wheel 432 connected to the driving motor 431 , and a driven wheel 433 cooperatively connected to the driving wheel 432 . The driven wheel 433 is fixedly connected to the rotating cavity 420 , and the driving motor 431 is fixed in the mounting groove 100 .

[0064] The driving motor 431 moves, driving the active wheel 432 to rotate, and the active wheel 432 drives the driven wheel 433 to rotate, thereby driving the rotating cavity 420 installed coaxially with the driven wheel 433. The rotating cavity 420 moves a certain angle accordingly and connects with different connecting pipes located in the fixed shell 410 to achieve different functions.

[0065] Hereinafter, the technical solution involved in the present application will be further described in conjunction with the accompanying drawings, taking the angle between the first through hole 421 and the second through hole 422 as an example of 90 degrees;

[0066] In this case, the angle between the first water inlet pipe 414 and the drain pipe 413, and the angle between the drain pipe 413 and the low water level drain pipe 412 located on the fixed shell 410 are also 90 degrees respectively. This arrangement angle is only an implementation method proposed to illustrate the specific process and is not limited to a 90-degree angle.

[0067] Initial water inflow process:

[0068] During the initial water intake and washing process, the driving motor 431 drives the rotating cavity 420 to rotate, connecting the first water inlet pipe 414 with the second through hole 422. At this time, the drain pipe 413, the low water level drain pipe 412, and the air duct 411 are blocked by the outer wall of the rotating cavity 420, and the first through hole 421 is blocked by the inner wall of the fixed shell 410.

[0069] The device to be cleaned is placed in the washing drum 200, and the water inlet pump 600 and the water pump 300 are both turned on. The washing water is input into the water collecting tank 500 from the second water inlet pipe 610, output to the return pipe 510 through the return water port below the water collecting tank 500, and after passing through the water pump 300, it enters the rotating cavity 420 from the first water inlet pipe 414 through the second through hole 422, enters the spray arm 800 from the water outlet 423 of the rotating cavity 420, and is sprayed from the spray arm 800 onto the utensil to be cleaned to rinse the utensil to be cleaned.

[0070] Mixed water inlet process:

[0071] When the washing water after flushing flows back to the sump 500, after being filtered by the filtering device, it circulates from the return water outlet of the sump 500 together with the external washing water through the return water pipe 510, the water pump 300 and the first water inlet pipe 414 to the rotating cavity 420 to continue spray flushing.

[0072] Drainage process:

[0073] The driving motor 431 rotates the rotating cavity 420 270 degrees clockwise or 90 degrees counterclockwise. At this time, the second through hole 422 is connected to the drain pipe 413, and the first through hole 421 is connected to the first water inlet pipe 414. The low water level drain pipe 412 and the air duct 411 are still blocked by the outer wall of the rotating cavity 420. The drain pipe 413 discharges the water in the rotating cavity 420. At this time, the recovered water in the sump 500 also continuously flows into the rotating cavity 420 through the first water inlet pipe 414 and is discharged outside the equipment together.

[0074] Low water level drainage process:

[0075] The driving motor 431 drives the rotating cavity 420 to rotate 90 degrees counterclockwise or 270 degrees clockwise. At this time, the drain pipe 413 is connected to the first through hole 421, and the low water level drain pipe 412 and the fan 700 are connected to the second through hole 422. The low water level drain pipe 412 inputs the residual water at the low water level in the water pump 300 housing into the rotating cavity 420, and then discharges it out of the equipment through the drain pipe 413. At the same time, the fan 700 is turned on, and dry air enters the rotating cavity 420 through the air duct 411, and enters the washing drum 200 from the water outlet 423 of the rotating cavity 420 to dry the cleaned utensils.

[0076] The technical solution involved in this application maximizes the use of the water pump 300 and the pipeline, simplifies the structure of the equipment, helps to reduce the size of the equipment, reduce the cost of the equipment, and is more practical.

[0077] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
