Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a dishwasher and a control method thereof. BACKGROUND

[0002] A dishwasher is a kind of kitchen appliance and is widely used in daily life. The dishwasher runs once to perform multiple cleaning modes, such as pre-washing, hot washing, rinsing, etc. Drainage is needed after each cleaning mode to achieve the cleaning of tableware.

[0003] In the related art, the dishwasher generally includes an inner container, a water tank, a filter screen, and a drain pipe. The water tank is arranged below the inner container and is in communication with the inner container. The filter screen is arranged at the opening of the water tank. The drain pipe is in communication with the water tank. In this way, when a cleaning mode is performed, water is introduced into the water tank and flows between the inner container and the water tank. When the water passes through the inner container, the tableware can be washed. Due to the arrangement of the filter screen, the impurities in the water are filtered and retained on the filter screen when the water passes through the filter screen. In this way, the impurities can be prevented from participating in the cleaning of the tableware again when the water circulates. After cleaning, the water in the water tank is drained through the drain pipe.

[0004] However, since the dishwasher includes multiple cleaning modes, some fine particles may be attached to the filter screen after one cleaning mode and are not drained out of the water tank. In this way, the fine particles attached to the filter screen may continue to participate in the next cleaning process, which may cause secondary pollution to the tableware. SUMMARY

[0005] The present application provides a dishwasher and a control method thereof to solve the problem that fine particles may be attached to the filter screen and thus repeatedly participate in different cleaning modes of the dishwasher, causing secondary pollution to the tableware.

[0006] In a first aspect, the present application provides a dishwasher, which includes a machine body, an inner container, a liquid containing member, a filter screen assembly, and a disturbance member. The inner container is arranged in the machine body and has a cavity. The liquid containing member is connected to the machine body and has a water tank. The opening of the water tank is in communication with the cavity, and the liquid in the water tank can flow between the water tank and the inner container. The filter screen assembly is arranged at the opening of the water tank. At least part of the disturbance member extends into the water tank to drive the liquid in the water tank to wash the filter screen assembly.

[0007] The dishwasher in the present application places tableware in the cavity when the tableware needs to be cleaned, and then introduces water into the tank. At this time, the first cleaning mode is entered, and the water circulates between the cavity and the water tank. When the water passes through the cavity, the tableware in the cavity can be cleaned.

[0008] When the water circulates between the tank and the cavity, the impurities in the water are filtered and attached to the filter screen assembly, so as to avoid the impurities in the water from participating in the cleaning process of the tableware each time.

[0009] After the first cleaning mode ends, the water is stored in the water tank, and a drainage mode is started to drain the water in the water tank. During the drainage process, the disturbing member is started to make the water wash the filter screen assembly, so that the fine particles attached to the filter screen assembly can fall off the filter screen assembly and be drained out of the water tank with the water in the water tank.

[0010] Since the disturbing member can disturb the water to wash the filter screen assembly, the fine particles attached to the filter screen assembly can be washed off by the water and drained out of the water tank with the water, so that when the next cleaning mode is entered, the fine particles can be avoided from entering the water, and the secondary pollution of the tableware can be avoided.

[0011] In some embodiments of the present application, the disturbing member comprises a first turbine shell, a first turbine and a first power member, the first turbine shell is arranged in the water tank, and the first turbine shell is provided with a first water inlet and a first water outlet which are in communication with the water tank; the first turbine is arranged in the first turbine shell; and the first power member is used to drive the first turbine to rotate.

[0012] Through the above arrangement, the first power member is used to drive the first turbine to rotate, so that the water can enter from the first water inlet and be drained out from the first water outlet. During the drainage process of the water, the water can wash the filter screen assembly to wash the particles on the filter screen assembly into the water and finally drain out of the water tank.

[0013] In some embodiments of the present application, the first power member comprises a second turbine shell, a second turbine, a rotating shaft, a connecting pipe and a first pump body, the second turbine shell is arranged outside the water tank, and the second turbine shell is provided with a second water inlet and a second water outlet; the second turbine is arranged in the second turbine shell, and the second turbine is coaxial with and spaced apart from the first turbine; the rotating shaft is arranged between the first turbine and the second turbine, and the rotating shaft is connected with the first turbine and the second turbine, and the first turbine is coaxially arranged with the second turbine through the rotating shaft; the first end of the connecting pipe is in communication with the water tank and faces the first water outlet, and the second end of the connecting pipe is in communication with the second water inlet; and the first pump body is connected to the connecting pipe and is used to drive the liquid in the connecting pipe to flow from the first end of the connecting pipe to the second end of the connecting pipe.

Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words such as "exemplary" or "for example" are intended to present the relevant concept in a specific manner.

[0050] The dishwasher is widely used in daily life as a kind of kitchen appliance. The dishwasher can replace human hands to clean tableware.

[0051] Based on this, as Figure 1As shown, the present application provides a dishwasher 10, comprising a body 100, an inner container 200, and a liquid container 300. The inner container 200 is disposed within the body 100, and defines a cavity therein. The liquid container 300 is connected to the body 100, and a water tank 310 is defined in the liquid container 300. The notch of the water tank 310 communicates with the cavity, allowing liquid in the water tank 310 to circulate between the water tank 310 and the inner container 200.

[0052] Through the above arrangement, when the tableware needs to be washed, the tableware is placed in the inner pot 200, and then the external water is passed into the water tank 310, and the water in the water tank 310 is circulated between the inner pot 200 and the water tank 310. When the water passes through the inner pot 200, the tableware in the inner pot 200 can be rinsed, thereby achieving the cleaning of the tableware.

[0053] For example, in order to connect the notch of the water tank 310 with the inner pot 200, the notch of the water tank 310 is formed below the body 100 so that the notch of the water tank 310 is connected with the inner pot 200. In this way, when water falls, it can directly fall into the notch of the water tank 310 and then flow into the water tank 310.

[0054] On this basis, in order to facilitate the circulation of liquid between the inner tank 200 and the water tank 310, as shown in FIG. Figure 1 As shown, the dishwasher 10 further includes a circulation pipe 400 , a spray head 410 , a second pump body 420 and a water inlet pipe 430 .

[0055] like Figure 1 As shown, the first end of the circulation pipe 400 is connected to the water tank 310. The nozzle 410 is disposed within the cavity, and the second end of the circulation pipe 400 is connected to the nozzle 410. The second pump body 420 is disposed on the circulation pipe 400 and is used to drive the liquid in the circulation pipe 400 from the first end of the circulation pipe 400 to the second end of the circulation pipe 400. The first end of the water inlet pipe 430 is connected to the water tank 310, and the second end of the water inlet pipe 430 is used to connect to a water source.

[0056] Thus, when washing dishes, water is introduced into the water tank 310, and then the second pump body 420 is activated, so that the water in the water tank 310 enters the circulation pipe 400, flows to the nozzle 410, and is then sprayed from the nozzle 410 onto the dishes in the cavity to wash the dishes. The water flowing off the dishes will flow back into the water tank 310, so that the water circulates between the water tank 310 and the inner pot 200, that is, the dishes can be repeatedly washed with limited water, which can save water.

[0057] In order to facilitate the placement of tableware in the inner container 200, as shown in FIG. Figure 1As shown, the dish washing machine 10 further comprises a rack 440, the rack 440 is arranged in the inner container 200, and dishes are placed on the rack 440, so that the dishes can be stably arranged in the inner container 200, and the dishes can be prevented from shaking under the washing of water flow, thereby avoiding the breakage of the dishes.

[0058] Exemplarily, as Figure 2 shown, the rack 440 can be provided with two, and the two racks 440 are arranged in a staggered manner along the arrangement direction of the liquid container 300 and the inner container 200, so that more dishes can be placed. Of course, the rack 440 can also be provided with one.

[0059] When the rack 440 is provided with two, the two racks 440 comprise an upper rack 441 and a lower rack 442, in order to facilitate the cleaning of the dishes on the rack 440, as Figure 2 shown, the spray head 410 is provided with multiple, along the arrangement direction of the upper rack 441 and the lower rack 442 (the vertical direction in Figure 2 , the inner container 200 and the upper rack 441 are provided with the spray head 410, the spray head 410 faces the upper rack 441, the upper rack 441 and the lower rack 442 are provided with the spray head 410, the spray head 410 faces the lower rack 442, the lower rack 442 and the inner container 200 are provided with the spray head 410, the spray head 410 faces the lower rack 442, and the multiple spray heads 410 are in communication with the second end of the circulating pipe 400.

[0060] In this way, during cleaning, the spray head 410 can wash the dishes on the first rack 440 and the dishes on the second rack 440 from multiple positions and in multiple directions. The dishes can be washed more fully, and the cleaning effect is improved.

[0061] Exemplarily, in order to realize the communication of the multiple spray heads 410 and the second end of the circulating pipe 400, as Figure 2 shown, the dish washing machine 10 further comprises multiple branch pipes 450 and a main pipe 460, the multiple branch pipes 450 correspond to the multiple spray heads 410 one by one, the first end of the branch pipe 450 is in communication with the spray head 410, the second end of the branch pipe 450 is in communication with the main pipe 460, and the main pipe 460 is in communication with the second end of the circulating pipe 400.

[0062] Through the above arrangement, the water in the circulating pipe 400 can flow into each branch pipe 450 through the main pipe 460, and then flow to the corresponding spray head 410. Due to the arrangement of the main pipe 460, the circulating pipe 400 can simultaneously supply water to multiple spray heads 410, reduce the pipe arrangement, and reduce the cost.

[0063] Since the water in the sink 310 is circulated between the sink 310 and the inner container 200 for cleaning the tableware, the impurities in the water (impurities after cleaning the tableware) will be repeatedly involved in the circulation of water to cause multiple pollution to the tableware.

[0064] Based on this, as shown in Figure 3 the above-mentioned dishwasher 10 further comprises a filter screen assembly 470, which is arranged at the slot of the sink 310. In this way, when the water passes through the slot of the sink 310, the impurities in the water will be filtered and left on the filter screen assembly 470, and the water will pass through the filter screen assembly 470 into the sink 310 to participate in the next cycle and continue to clean the tableware. Due to the presence of the filter screen assembly 470, the impurities in the water can be prevented from causing multiple pollution to the tableware, and the cleaning effect is guaranteed.

[0065] Exemplarily, as shown in Figure 4 the filter screen assembly 470 comprises a coarse filter screen 471 and a fine filter screen 472. The coarse filter screen 471 is arranged in the inner container 200 and covers the slot of the sink 310. The fine filter screen 472 is arranged in the sink 310 and connected with the sink 310. The fine filter screen 472 is in the shape of a barrel, and the opening of the fine filter screen 472 faces the opening of the inner container 200.

[0066] In this way, when the water passes through the coarse filter screen 471, the coarse filter screen 471 will filter out the larger impurities in the water, and the smaller impurities will enter the fine filter screen 472 and be filtered out by the fine filter screen 472. In this way, the impurities in the water can be removed as much as possible, thereby guaranteeing the cleaning effect of the tableware.

[0067] After the cleaning is completed, the water in the sink 310 needs to be drained. During the draining process, part of the fine impurities on the fine filter screen 472 will be drained out of the sink 310 with the water.

[0068] Since the dishwasher 10 operates once, a plurality of cleaning modes such as pre-washing, hot washing, rinsing, etc. will be performed, and after each cleaning mode is completed, the water needs to be drained. Since part of the fine particles may still be attached to the fine filter screen 472 after each cleaning mode is completed and are not drained out of the sink 310 with the water, the impurities may be involved in the circulation of water again when the next cleaning mode is performed, thereby causing secondary pollution to the tableware.

[0069] Based on this, as shown in Figure 5 the dishwasher 10 provided by the present application further comprises a disturbing member 500, which at least partially extends into the sink 310 to drive the liquid in the sink 310 to flush the filter screen assembly 470.

[0070] Through the above arrangement, since the disturbing member 500 can disturb the water to wash the filter screen assembly 470, the fine particles adhered on the filter screen assembly 470 can be washed away by the water and discharged out of the sink 310 with the water, so that when the next cleaning mode is entered, the fine particles can be prevented from entering the water, and the secondary pollution to the tableware can be avoided.

[0071] Exemplarily, as shown in Figure 6 The disturbing member 500 can include a first turbine shell 510, a first turbine 520 and a first power member 530. The first turbine shell 510 is arranged in the sink 310, and a first water inlet 511 and a first water outlet 512 are formed in the first turbine shell 510 and communicate with the sink 310. The first turbine 520 is arranged in the first turbine shell 510. The first power member 530 is used to drive the first turbine 520 to rotate. The first power member 530 is connected with the first turbine 520. At least part of the first power member 530 can be arranged outside the sink 310.

[0072] In this way, when the water needs to be disturbed, the first power member 530 can be started to drive the first turbine 520 to rotate. In the process of rotation of the first turbine 520, the sewage in the sink 310 can enter from the first water inlet 511 and be discharged from the first water outlet 512. In the process of entering and discharging of the sewage, the sewage can be disturbed to impact the filter screen assembly 470, so that the fine particles adhered on the filter screen assembly 470 can fall into the water, and then the water is drained to discharge the fine particles out of the sink 310 with the water. In this way, the secondary pollution can be avoided.

[0073] Alternatively, the disturbing member 500 can also include a vibrating rod. When the vibrating rod is started, the vibrating rod can vibrate in the sink 310, so that the water in the sink 310 can be disturbed to wash the filter screen assembly 470, so as to reduce the secondary pollution.

[0074] Alternatively, the disturbing member 500 can also include a stirring rod. The stirring rod is driven by a motor or other components to stir the water, so that the water in the sink 310 can be disturbed to wash the filter screen assembly 470, so as to reduce the secondary pollution. The disturbing member 500 can also be any other suitable component, which will not be listed one by one herein.

[0075] On this basis, in order to drive the first turbine 520 to rotate by the first power member 530, as shown in Figure 7 The first power member 530 can include a second turbine shell 531, a second turbine 532, a rotating shaft 533, a connecting pipe 534 and a first pump body 535.

[0076] The second turbine shell 531 is arranged outside the sink 310, and the second turbine shell 531 is provided with a second water inlet 5311 and a second water outlet 5312. The second turbine 532 is arranged in the second turbine shell 531, and the second turbine 532 is coaxial with and spaced from the first turbine 520. The rotating shaft 533 is arranged between the first turbine 520 and the second turbine 532, and the rotating shaft 533 is connected with the first turbine 520 and the second turbine 532, and the first turbine 520 is coaxial with the second turbine 532 through the rotating shaft 533. The first end of the connecting pipe 534 is communicated with the sink 310, and the first end of the connecting pipe 534 faces the first water outlet 512, and the second end of the connecting pipe 534 is communicated with the second water inlet 5311. The first pump body 535 is connected to the connecting pipe 534, and is used to drive the liquid in the connecting pipe 534 to flow from the first end of the connecting pipe 534 to the second end of the connecting pipe 534.

[0077] Through the cooperation of the above-mentioned components, when it is necessary to stir the water in the sink 310, the first pump body 535 is started, so that the water in the sink 310 enters the second turbine shell 531 through the connecting pipe 534, and under the impact of the water, the second turbine 532 rotates, and under the rotation of the second turbine 532, the water is discharged from the second water outlet 5312 to the outside, so as to realize the drainage. At the same time, the first turbine 520 also rotates with the second turbine 532, so that the water in the sink 310 enters from the first water inlet 511 and is discharged from the first water outlet 512, so as to make the water in the sink 310 fluctuate, thereby realizing the washing of the filter screen and reducing the secondary pollution.

[0078] Since the first turbine 520 is driven to rotate by using the first power member 530, the power during drainage is utilized, so that the reuse of water can be realized, the energy consumption is reduced, and energy saving and environmental protection are achieved.

[0079] In other embodiments, the above-mentioned first power member 530 can also include a motor, and the output shaft of the motor is in transmission connection with the first turbine 520, and the motor is used to drive the first turbine 520 to rotate, so as to disturb the water in the sink 310.

[0080] For example, the output shaft of the motor is connected with the center of the first turbine 520, and the output shaft of the motor is coaxial with the first turbine 520, so that the output shaft of the motor can drive the first turbine 520 to rotate in the process of rotation.

[0081] When the water in the sink 310 is about to be drained, some air will enter the sink 310 and the connecting pipe 534 and then the first pump body 535. At this time, the centrifugal force generated by the air after rotation is smaller because the density of the air is smaller than that of the water. At this time, the low pressure formed in the central area of the impeller in the first pump body 535 is not enough to suck water into the first pump body 535. Although the first pump body 535 is rotating, it cannot drain water. That is, the first pump body 535 will appear air binding phenomenon, so that some water (about 100 ml) will be left in the sink 310.

[0082] Therefore, as shown in the drawings, the dish washing machine 10 provided by the present application further comprises a bypass pipe 600. A first end of the bypass pipe 600 is in communication with the second water inlet 5311, and a second end of the bypass pipe 600 is used to be in communication with a water source. Figure 8

[0083] By arranging the bypass pipe 600, external water is introduced into the second turbine shell 531 to flush the residual sewage in the second turbine shell 531 out of the external. At the same time, when the water enters the second turbine shell 531, the second turbine 532 in the second turbine shell 531 will also be driven to rotate, and the second turbine 532 will drive the first turbine 520 to rotate through the rotating shaft 533. In this way, the residual water in the first turbine shell 510 and the sink 310 can enter the first pump body 535, and then be drained into the second turbine shell 531 and finally be drained out of the second turbine shell 531. In this way, the residual sewage in the first turbine shell 510 and the second turbine shell 531 can be avoided, so that the peculiar smell can be avoided.

[0084] It can be understood that, as shown in the drawings, the dish washing machine 10 further comprises a drain pipe 700. One end of the drain pipe 700 is in communication with the second water outlet 5312, so that the water in the second turbine shell 531 can be drained out of the external through the drain pipe 700. By arranging the drain pipe 700, the water in the second turbine shell 531 can be guided to any suitable place to achieve water drainage. Figure 9

[0085] Among them, the second end of the bypass pipe 600 is in communication with the water source, which can be directly in communication with the external water faucet.

[0086] Alternatively, as shown in the drawings, the dish washing machine 10 further comprises a valve 610. The second end of the bypass pipe 600 can also be in communication with the sink 310. The valve 610 is arranged on the bypass pipe 600 and is used to control the on-off of the bypass pipe 600. Figure 9

[0087] ​​​Since the external water can enter the water tank 310 through the water inlet pipe 430, when water needs to be supplied, the external water can be first supplied into the water tank 310, and then the valve 610 is opened to make the bypass pipe 600 conductive, so that the water in the water tank 310 can enter the second turbine shell 531 through the bypass pipe 600 to realize the flushing of the inside of the second turbine shell 531.

[0088] Since the flushing process and the above-mentioned cleaning process use the same water source, the complexity of the pipeline arrangement can be reduced, thereby reducing the cost.

[0089] The valve 610 can be a solenoid valve, which has the advantages of fast action and low price.

[0090] Since the bypass pipe 600 and the connecting pipe 534 are both connected between the water tank 310 and the second turbine 532, in order to avoid the water entering the second turbine shell 531 through the bypass pipe 600 from flowing back to the water tank 310 through the connecting pipe 534, as shown in Figure 10 The dishwasher 10 also includes a check valve 620 arranged on the connecting pipe 534 to prevent liquid from flowing from the second turbine shell 531 to the water tank 310 through the connecting pipe 534.

[0091] By arranging the check valve 620 on the connecting pipe 534, water can be prevented from flowing back to the water tank 310 through the connecting pipe 534, so that the liquid can only be discharged to the outside of the second turbine shell 531 through the second water outlet 5312. Thus, the drainage efficiency is ensured.

[0092] Similarly, in order to avoid the water entering the second turbine shell 531 through the connecting pipe 534 from flowing back to the water tank 310 through the bypass pipe 600, as shown in Figure 10 The check valve 620 is also arranged on the bypass pipe 600 to prevent liquid from flowing from the second turbine shell 531 to the water tank 310 through the bypass pipe 600.

[0093] By arranging the check valve 620 on the bypass pipe 600, water can be prevented from flowing back to the water tank 310 through the bypass pipe 600, so that the liquid can only be discharged to the outside of the second turbine shell 531 through the second water outlet 5312. Thus, the drainage efficiency is ensured.

[0094] In some embodiments, the check valve 620 is also arranged on the drain pipe 700 to prevent the water discharged to the outside of the second turbine shell 531 from flowing back into the second turbine shell 531, thereby ensuring the drainage efficiency. At the same time, it can also avoid water remaining in the second turbine shell 531.

[0095] The check valve 620 can be a check rubber tongue, or can also be any other suitable check valve 620.

[0096] After the end of the dish washing, there are a lot of high-temperature steam left in the cavity, and a lot of water left on the dishes. At this time, the dishes need to be dried. Specifically, as shown in the drawings, a through hole is formed in the inner container 200 and communicates with the cavity. The dish washing machine 10 further comprises a second power member 800 for driving the rotating shaft 533 to rotate. The second power member 800 can be connected to the rotating shaft 533. Figure 11

[0097] In this way, when the dishes need to be dried, the second power member 800 is started to drive the rotating shaft 533 to rotate. In the process of rotating the rotating shaft 533, the first turbine 520 and the second turbine 532 will rotate at the same time, and negative pressure will be generated in the first turbine shell 510 and the second turbine shell 531. In this way, the high-temperature steam in the cavity can be sucked out and discharged to the outside through the water tank 310, the connecting pipe 534, the second turbine shell 531 and the drain pipe 700, which can directly reduce the moisture in the air in the cavity.

[0098] At the same time, in the process of discharging the water vapor, the external air also enters the cavity through the through hole and then flows to the outside of the second turbine shell 531. In the process of flowing, the air can take away the moisture on the dishes to achieve drying of the dishes.

[0099] And because the air passes through the water tank 310, the connecting pipe 534 and the second turbine shell 531, the air can dry the moisture in the water tank 310, the connecting pipe 534 and the second turbine shell 531 in the process, so that the inside can be kept dry.

[0100] Compared with the related art of directly using a fan to dry the moisture on the dishes, the scheme in the present application first discharges the high-temperature steam in the air, which can avoid the moisture in the air from adhering to the dishes after the moisture on the dishes is dried, so the scheme in the present application can have better drying effect.

[0101] At the same time, compared with the related art of naturally drying the dishes by opening the door, the scheme in the present application does not need to open the door, which can avoid small organisms such as cockroaches from entering the cavity. At the same time, because the steam in the present application is discharged into the sewer through the drain pipe 700, it can avoid the steam from being directly discharged into the kitchen, so as to ensure the dryness of the kitchen.

[0102] The second power member 800 can be a motor, so that the output shaft of the motor is coaxially arranged with the rotating shaft 533, and the output shaft of the motor is connected with the rotating shaft 533, so as to drive the rotating shaft 533 to rotate by the motor.

[0103] ​Alternatively, the second power member 800 comprises a worm wheel, a worm gear and a motor, the worm wheel is sleeved on the rotating shaft 533 and fixedly connected with the rotating shaft 533, so that the worm wheel and the worm gear are engaged, and the motor drives the worm gear to rotate.

[0104] In this way, when the second power member 800 is started, the motor is started, so that the motor drives the worm gear to rotate, and drives the worm wheel to rotate, thereby driving the rotating shaft 533 to rotate. The cooperation of the worm wheel and the worm gear can facilitate the position setting of the motor and the space layout.

[0105] After the drying is completed, there may still be some moisture in the cavity, and the user may forget or not have time to take out the tableware to the outside of the cavity.

[0106] In this case, in order to avoid the tableware from mildewing or having an odor, the dishwasher 10 further comprises a timing device and a controller, the timing device is used for setting a preset working time of the second power member 800 and a preset interval time length of adjacent two times of working of the second power member 800. The controller is electrically connected with the second power member 800 and the timing device.

[0107] The controller is configured to acquire the preset working time and the preset interval time length of adjacent two times of working of the second power member 800. In a case where an actual interval time length of adjacent two times of working of the second power member 800 is greater than or equal to the preset interval time length of adjacent two times of working of the second power member 800, the controller controls the second power member 800 to start and run for the preset working time.

[0108] Through the above setting, when the tableware is not taken out from the cavity in time, the storage mode can be started. Specifically, when the actual interval time length of adjacent two times of working of the second power member 800 is greater than or equal to the preset interval time length, the second power member 800 is started, so that the external air enters the cavity through the through hole, and then is discharged to the outside through the water tank 310, the connecting pipe 534, the second turbine shell 531 and the drain pipe 700, so as to realize the renewal of the air in the cavity, so that the air in the cavity is kept fresh, and the tableware is prevented from having an odor.

[0109] The preset working time can be 5 minutes, 10 minutes or 15 minutes. The actual situation can be set.

[0110] In addition, the preset interval time length of adjacent two times of working of the second power member 800 can be two hours, three hours or four hours. The actual situation can be set.

At the same time, the water entering the second turbine shell 531 drives the second turbine 532 to rotate, and the second turbine 532 drives the first turbine 520 to rotate through the shaft 533, so as to disturb the water in the sink 310, so that the water in the sink 310 washes the filter screen assembly 470, and the fine particles attached to the filter screen assembly 470 fall into the water and are then discharged to the outside of the second turbine shell 531.
