[0052] Embodiments 1-6, this embodiment further provides a dishwasher, comprising a self-cleaning water supply assembly 1 and a residue collection and filtering system as described in Embodiment 1, wherein the water inlet channel 511 of the self-cleaning spray arm 5 is connected to the water collection chamber 21 or tap water through the self-cleaning water supply assembly 1.

[0053] In this embodiment, the water inlet channel 511 of the self-cleaning spray arm 5 is connected to the water collecting chamber 21 through the self-cleaning water supply component 1 as an example. The communication mode between the self-cleaning water supply component 1 and the water collecting chamber 21 includes but is not limited to any of the following:

[0054] refer to Figure 3-5, the first type, the self-cleaning water supply component 1 is connected to the water collection chamber 21 through the drainage pump 4 and the drainage port 221 of the water cup component 2 in sequence. At this time, the self-cleaning water supply component 1 includes a three-way control valve 11, a slag collection cleaning water pipe 12 and a drainage pipe 13. The three-way control valve 11 has a valve cavity, a water inlet, a first water outlet and a second water outlet. The valve cavity is connected to the water inlet, the first water outlet and the second water outlet respectively. The water inlet of the three-way control valve 11 is connected to the drainage port 221 of the water cup component 2 through the drainage pump 4, the first water outlet of the three-way control valve 11 is connected to the sewer through the drainage pipe 13, and the second water outlet of the three-way control valve 11 is connected to the water inlet channel 511 through the slag collection cleaning water pipe 12. Therefore, by switching different waterways through the three-way control valve 11, the water in the water cup component 2 can be provided to the self-cleaning spray arm 5 through the self-cleaning water supply component 1, or the water in the water cup component 2 can be discharged in time, so as to realize the drainage function of the dishwasher.

[0055] refer to Figure 6 , the second type, the self-cleaning water supply assembly 1 is connected to the water collection chamber 21 through the washing pump 7 and the washing water outlet of the water cup assembly 2 in sequence. At this time, the self-cleaning water supply assembly 1 includes a three-way control valve 11 and a slag collection cleaning water pipe 12. The three-way control valve 11 has a valve cavity, a water inlet, a first water outlet and a second water outlet. The valve cavity is connected to the water inlet, the first water outlet and the second water outlet respectively. The water inlet of the three-way control valve 11 is connected to the washing water outlet of the water cup assembly 2 through the washing pump 7. The first water outlet of the three-way control valve 11 is directly connected to the spray arm assembly 6 of the dishwasher. The second water outlet of the three-way control valve 11 is connected to the water inlet channel 511 through the slag collection cleaning water pipe 12. Therefore, by switching different waterways through the three-way control valve 11, the water in the water cup assembly 2 can be provided to the self-cleaning spray arm 5 or the spray arm assembly 6 through the self-cleaning water supply assembly 1, so as to realize the self-cleaning function of the dishwashing and filtering system of the dishwasher.

[0056] refer to Figure 3 The drain pump 4 includes a pump housing 41, an impeller 42, a slag-crushing knife 43 and a driver 44. The pump housing 41 is provided with a pump chamber 411, a drainage inlet 412 and a drainage outlet 413. The pump chamber 411 is connected to the drainage outlet 221 through the drainage inlet 412, and the pump chamber 411 is connected to the sewer or the water inlet of the three-way control valve 11 through the drainage outlet. The impeller 42 and the slag-crushing knife 43 are both rotatably arranged in the pump chamber 411. The driver 44 is arranged at the top of the pump housing 41, and its output end is respectively connected to the impeller 42 and the slag-crushing knife 43, which is used to drive the impeller 42 and the slag-crushing knife 43 to rotate, so that drainage and slag-crushing can be performed simultaneously. Thus, the drain pump 4 has the dual functions of drainage and slag-crushing. Due to the shared slag-crushing and drainage integrated design in the pump housing 41, the slag-crushing and slag-discharging structure of the dishwasher is further optimized and improved, the slag-discharging function of the dishwasher is improved, and the technical problems that the existing dishwasher filter system cannot automatically discharge food residues and has poor foreign body resistance are solved.

[0057] Combine the following Figure 5 To illustrate the working principle of the dishwasher of this embodiment:

[0058] See also Figure 5 The drainage function control method of the dishwasher is mainly controlled by the conversion structure of the three-way control valve 11. When the dishwasher enters the drainage stage, the three-way control valve 11 controls the first water outlet to open and the second water outlet to close. At this time, the drainage waterway is connected, the driver 44 in the drainage pump 4 works, and the drainage impeller 42 and the slag crushing knife 43 work at the same time. At this time, the dishwasher can not only realize the drainage function, but also realize the slag crushing function, thereby enhancing the drainage and slag discharge capacity of the dishwasher.

[0059] The self-cleaning function control method of the dishwasher is mainly controlled by the conversion structure of the three-way control valve 11. When the dishwasher enters the final drying end stage, the self-cleaning spray arm 5 starts to work. The three-way control valve 11 controls the first water outlet to be closed and the second water outlet to be opened. At this time, the self-cleaning water circuit is connected, the driver 44 in the drainage pump 4 works, and the drainage impeller 42 and the slag crushing knife 43 work at the same time to supply the water in the water cup assembly 2 to the self-cleaning spray arm 5. The spray arm body 52 rotates 360 degrees in all directions under the action of the water flow to clean the filter assembly 3; during the cleaning process, since the slag crushing knife 43 also rotates and works, it can not only realize the automatic cleaning function of the slag collection and filtering system, but also realize the slag crushing function. When the dishwasher is finished cleaning, the three-way control valve 11 switches the water circuit and starts the drainage function.

[0060] It can be seen that the automatic cleaning function of the residue filtering system has been realized before the end of the program, thereby solving the problem that the residue filtering system does not need to be removed for separate cleaning, thereby basically solving the problem of the residue filtering system being free of cleaning, and at the same time dealing with the residue problem to prevent odor from being generated in the dishwasher cavity.

[0061] Combine the following Figure 6 To illustrate the working principle of the dishwasher of this embodiment:

[0062] See also Figure 6 , the tableware washing function control method of the dishwasher: it is mainly controlled by the conversion structure of the three-way control valve 11. When the dishwasher enters the washing stage, the three-way control valve 11 controls the first water outlet to open and the second water outlet to close. At this time, the washing water circuit is connected, and the washing pump 7 works to provide the spray arm assembly 6 with the water required for washing the tableware, forming a cycle cleaning, and finally achieving the cleanliness of the tableware.

[0063] The self-cleaning function control method of the dishwasher is mainly controlled by the conversion structure of the three-way control valve 11. When the dishwasher enters the final drying end stage, the self-cleaning spray arm 5 starts to work. The three-way control valve 11 controls the first water outlet to be closed and the second water outlet to be opened. At this time, the self-cleaning water circuit is connected, and the washing pump 7 works to supply the water in the water cup assembly 2 to the self-cleaning spray arm 5. The spray arm body 52 rotates 360 degrees in all directions under the action of the water flow to clean the filter assembly 3; during the cleaning process, since the drainage pump 4 works, and the drainage impeller 42 and the slag crushing knife 43 in the drainage pump 4 work at the same time, not only the automatic cleaning function of the slag collection and filtering system can be realized, but also the slag crushing and drainage functions can be realized.

A cleaning component 82 for cleaning the inside of the range hood is provided inside the range hood module 8, and the cleaning component 82 is connected to the first water outlet of the three-way control valve 11 through the range hood cleaning pipe 45, thereby providing a water supply solution for the range hood module, freeing the user's hands, and at the same time eliminating the cleaning water cup of the range hood module.

[0066] When the three-way control valve 11 controls the first water outlet to open and the second water outlet to close, the drain pump 4 is started and the water cup assembly 2 is drained. When the turbidity of the water in the water cup assembly 2 is high, this part of the water is directly discharged to the sewer. When the turbidity of the water in the water cup assembly 2 is low and the range hood module 8 needs to be cleaned, under the action of the drain pump 4, this part of the water is supplied to the cleaning assembly 82 inside the range hood module 8 through the range hood cleaning pipe 45. After cleaning the inside of the range hood, the cleaning water is collected in the oil collecting chamber 81, and then discharged to the sewer through the sewage pipe 46 and the drain pipe 13 of the dishwasher.
