[0037] It should be noted that these figures and descriptions are not intended to limit the scope of the concept of this application in any way, but rather to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0039] In the description of this application, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "longitudinal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] like Figures 1 to 5As shown in the illustration, this application describes a self-cleaning dishwasher, including a washing chamber 100. The washing chamber 100 has an opening on one side and a door 500 corresponding to the opening, allowing the user to place tableware into the washing chamber 100 for washing and other treatments using water. The dishwasher in this application can be any existing model, such as a top-loading sink dishwasher, a front-loading built-in dishwasher, a pull-out drawer dishwasher, etc.

[0042] Meanwhile, a recessed water collection tank 200 is provided on the bottom wall below the washing chamber 100 of the dishwasher, so that all the washing water in the washing chamber 100 is collected and flows into the water collection tank 200. Then, the washing water passage 301 connected to the water collection tank 200 is connected to the spray structure 400 installed in the washing chamber 100. A washing pump 311 is installed on the washing water passage 301. The washing pump 311 provides water flow driving force to drive the washing water in the water collection tank 200 to the spray structure 400 through the washing water passage 301. Finally, water is sprayed into the washing chamber 100 through the spray holes provided on the spray structure 400, so that the spray water washes and rinses the dishes to be processed in the washing chamber 100. The aforementioned spray structure 400 can be any existing structure capable of spraying and washing the tableware in the washing chamber 100 with water, such as a spray arm that can rotate around an axis, with multiple spray holes arranged on the spray arm facing different directions, so as to drive the spray arm to rotate around the axis using the spray water flow, and spray water into various areas of the washing chamber 100 through the spray holes during the rotation process.

[0043] Furthermore, the dishwasher is equipped with a drain water path 302, on which a drain pump 321 is installed. The drain water path 302 discharges the washing water in the water collection tank 200 after the dishwasher has finished working. Of course, the washing pump 311 and the drain pump 321 can also be combined into one unit. By utilizing the pump's own forward and reverse rotation, or by cooperating with the opening and closing of the valve body on the water path 300, water can be supplied from the water collection tank 200 to the washing water path 301 or the drain water path 302 respectively.

[0044] In existing dishwashers, during use, food residue on dishes in the washing chamber 100 is washed down to the bottom of the chamber by the washing water and then collected in the water collection tank 200. To prevent residue from entering the water pipe 300, a filter assembly 2 is typically installed in the water collection tank 200 to trap the residue, thus preventing blockages and damage to the pump. However, after use, the residue trapped by the filter assembly 2 remains in the water collection tank 200, requiring manual disassembly and cleaning by the user, resulting in a cumbersome second manual operation.

[0045] To solve the above problems, the technical solution adopted in this application is as follows:

[0046] like Figures 1 to 5 As shown, a self-cleaning dishwasher includes: a washing chamber 100, a water collection tank 200 in the washing chamber 100, and a self-cleaning filter structure installed in the water collection tank 200. The self-cleaning filter structure intercepts and filters the residue in the washing chamber 100, and can crush the intercepted residue in real time to prevent the residue in the dishwasher from accumulating and remaining at the filter structure, thereby achieving the effect of cleaning and maintenance-free filter components 2 of the dishwasher, greatly improving the convenience of using the dishwasher for users.

[0047] In this embodiment, the specific structure of the dishwasher-compatible self-cleaning filter structure described above is as follows:

[0048] like Figures 1 to 5 As shown, a self-cleaning filter structure for a dishwasher includes a filter chamber 1, in which a filter assembly 2 and a pulverizing assembly 3 are disposed; and a drive device 4 having two power output ends 41, which are respectively connected to at least a portion of the filter assembly 2 and / or at least a portion of the pulverizing assembly 3, driving the pulverizing assembly 3 to generate relative movement with the filter assembly 2, thereby pulverizing the residue intercepted by the filter assembly 2.

[0049] With the above settings, the filter component 2 filters and intercepts dishwasher residue, and the filter component 2 and the crushing component 3, which move in opposite directions, crush the intercepted residue to achieve the effect of automatic cleaning of the filter component 2. This results in a significant technological advancement in making the dishwasher's filter component 2 maintenance-free.

[0050] For ease of description, this application takes the example of the water collection tank 200 of the dishwasher directly forming the filter chamber 1. Of course, an independent chamber can also be set in the water collection tank 200 to form the filter chamber 1, or an independent chamber can be set in the washing chamber 100 or the water channel 300 to form the filter chamber 1. Setting the cleaning-free filter structure in other parts of the washing chamber 100 of the dishwasher or the water channel 300 still falls within the protection scope of this application.

[0051] Example 1

[0052] like Figures 1 to 3 As shown in the figure, this embodiment introduces a self-cleaning filter structure for a dishwasher, which includes a filter chamber 1, a filter assembly 2 and a pulverizing assembly 3 disposed in the filter chamber 1; and a driving device 4 having two power output ends 41, which are respectively connected to at least a portion of the filter assembly 2 and / or at least a portion of the pulverizing assembly 3, driving the pulverizing assembly 3 to generate relative movement with the filter assembly 2, and pulverizing the residue intercepted by the filter assembly 2.

[0053] In this embodiment, the drive device 4 has a first power output terminal 411 and a second power output terminal 412; the first power output terminal 411 is connected to the filter assembly 2, and the second power output terminal 412 is connected to the pulverizing assembly 3. Through this arrangement, relative movement occurs between the filter assembly 2 and the pulverizing assembly 3. This relative movement is used to pulverize the residue intercepted by the filter assembly 2, thereby achieving the effect of automatically cleaning the filter assembly 2.

[0054] In this embodiment, the filter assembly 2 includes a filter element 20, which can be a cylindrical filter screen that rotates around a vertical axis. The cylindrical filter screen divides the filter chamber 1 into a filtered chamber 102 on the outer periphery and a chamber to be filtered 101 on the inner periphery. The upper opening of the chamber to be filtered 101 is connected to the washing chamber 100, and the filtered chamber 102 is connected to the water passage 300. This allows the washing water in the washing chamber 100 to flow into the water passage 300 after passing through the chamber to be filtered 101, the filter element 20, and the filtered chamber 102 in sequence, thereby achieving the effect of filtering and intercepting the residue in the washing water and trapping it in the chamber to be filtered 101.

[0055] In this embodiment, the pulverizing component 3 includes a pulverizing element 30, which is any or a combination of existing grinding structures such as blade structure, grinding disc structure, roller structure, grinding sleeve structure, etc. The pulverizing element 30 is used to pulverize the residue by means of rotational force. The pulverizing element 30 is disposed in the filter chamber 101 and is in direct contact with the residue filtered and intercepted by the filter element 20, so that the filter element 20 and the pulverizing element 30 rotate relative to each other around the axis and the intercepted residue is pulverized by means of relative rotational force.

[0056] In this embodiment, the drive device 4 is installed on the outside of the filter chamber 1. The drive device 4 has two power output ends 41, a first power output end 411 and a second power output end 412. The first power output end 411 and the second power output end 412 are respectively output shafts 431 that pass through the bottom wall of the filter chamber 1 and enter the filter chamber 101. The first power output end 411 is coaxially connected to the filter element 20 and the crushing element 30 is coaxially connected to the second power output end 412. They are used to drive the crushing element 30 and the filter element 20 to rotate around the shaft respectively. The relative movement generated by the rotation of the two around the shaft is used to crush the residue.

[0057] Meanwhile, in this embodiment, in order to achieve the effect of relative rotation between the filter element 20 and the pulverizer 30, the first power output terminal 411 and the second power output terminal 412 respectively output a first rotation speed and a second rotation speed. The rotation direction and rotation speed of the first rotation speed and the second rotation speed are at least partially different, so that the filter element 20 and the pulverizer 30 generate relative rotation, and the residue between them is ground and pulverized by the relative rotation action.

[0058] Of course, in this embodiment, only the cylindrical filter screen as the filter component 2 and the pulverizer 30 set inside the cylindrical filter screen are used as examples for discussion. Other structural forms of filter component 2 and pulverizer 3 can also be set. The driving device 4 drives the filter component 2 and the pulverizer 3 to move in different directions and at different speeds, so that the filter component 2 and the pulverizer 3 generate relative movements. The relative movements are used to pulverize the residue in the filter chamber 1, so that the pulverized residue is carried by the flowing water and flows through the filter component 2 and out of the filter chamber 1, thereby achieving the effect of self-cleaning and maintenance-free filter component 2.

[0059] Example 2

[0060] like Figure 1 and Figure 4 As shown in the figure, this embodiment introduces a self-cleaning filter structure for a dishwasher, which includes a filter chamber 1, a filter assembly 2 and a pulverizing assembly 3 disposed in the filter chamber 1; and a driving device 4 having two power output ends 41, which are respectively connected to at least a portion of the filter assembly 2 and / or at least a portion of the pulverizing assembly 3, driving the pulverizing assembly 3 to generate relative movement with the filter assembly 2, and pulverizing the residue intercepted by the filter assembly 2.

[0061] In this embodiment, the filter assembly 2 includes a first filter element 21 and a second filter element 22; the first power output terminal 411 of the drive device 4 is connected to the first filter element 21, and the second power output terminal 412 of the drive device 4 is connected to the second filter element 22. Through this arrangement, different components of the filter assembly 2 can generate relative movements, using these relative movements to crush the intercepted residue. The crushed residue then flows through the filter assembly 2 with the water flow and exits the filter chamber 1, thereby achieving a self-cleaning and maintenance-free effect for the filter assembly 2.

[0062] In this embodiment, the first filter element 21 and the second filter element 22 are inner and outer cylindrical filter screens; the outer first filter element 21 is coaxially connected to the first power output end 411, and is used to drive the first filter element 21 to generate a first rotation around the axis; the inner second filter element 22 is coaxially connected to the second power output end 412, and is used to drive the second filter element 22 to generate a second rotation around the axis; wherein, at least part of the direction of rotation and speed of the first rotation and the second rotation are different. Optionally, the rotation directions of the first rotation and the second rotation are different, so as to utilize the relative non-directional rotation around the axis between the first filter element 21 and the second filter element 22 to realize the crushing of the residue between the two filter elements 20, so that the crushed residue can flow out of the filter chamber 1 with the water flow.

[0063] In this embodiment, a pulverizing component 3 can also be provided in the inner second filter element 22. When the second filter element 22 rotates around its axis, it rotates relative to the pulverizing component 3. This relative rotational motion pulverizes the residue trapped on the inner periphery of the second filter element 22, allowing the pulverized residue to pass through the first filter element 21 and enter the space between the first and second filter elements 21 for further pulverization. Of course, to achieve the above effect, the mesh size of the first filter element 21 needs to be larger than that of the second filter element 22, so that larger pulverized residues can pass through the second filter element 22 but not the first filter element 21, achieving the effect of batch-wise pulverization of the residue.

[0064] Furthermore, in this embodiment, the first filter element 21 and / or the second filter element 22 are provided with radially arranged concave and convex portions, so as to improve the crushing effect by utilizing the staggered concave and convex portions on the two filter elements 20, so that the relative rotational motion between the two filter elements 20 can further improve the crushing efficiency of the residue.

[0065] Of course, in this embodiment, only the inner and outer double-sided cylindrical filter screen is used as the filter component 2 as an example for discussion. Other structural forms of filter component 2 and crushing component 3 can also be set. The driving device 4 drives different parts of filter component 2 to move in different directions and at different speeds, so that the different parts of filter component 2 and filter component 2 and crushing component 3 generate relative movements. The relative movements are used to crush the residue in filter chamber 1, so that the crushed residue is carried by the flowing water and flows through filter component 2 and out of filter chamber 1, thereby achieving the effect of self-cleaning and maintenance-free filter component 2.

[0066] Alternatively, in this embodiment, the first filter element 21 or the second filter element 22 is connected to the pulverizing assembly 3 to drive the pulverizing assembly 3 to rotate together with the first filter element 21 or the second filter element 22, thereby improving the pulverizing effect on the residue trapped by the filter element. Of course, when the filter element 2 and the pulverizing assembly 3 adopt other existing structural forms, the first power output terminal 411 and / or the second power output terminal 421 of the driving device 4 can also be simultaneously connected to at least a portion of the pulverizing assembly 3 and at least a portion of the filter element 2; for example, the first power output terminal 411 of the driving device 4 can be simultaneously connected to the first pulverizing element 31 and the first filter element 21, causing the first pulverizing element 31 and the first filter element 21 to rotate together; the second power output terminal 412 can be simultaneously connected to the second pulverizing element 32 and the second filter element 22, causing the second pulverizing element 32 and the second filter element 22 to rotate together, and causing differential rotation between the different pulverizing elements 30 and the different filter elements 20, thereby further improving the residue pulverizing efficiency. (Not shown in the accompanying drawings)

[0067] Example 3

[0068] like Figure 1 and Figure 5 As shown in the figure, this embodiment introduces a self-cleaning filter structure for a dishwasher, which includes a filter chamber 1, a filter assembly 2 and a pulverizing assembly 3 disposed in the filter chamber 1; and a driving device 4 having two power output ends 41, which are respectively connected to at least a portion of the filter assembly 2 and / or at least a portion of the pulverizing assembly 3, driving the pulverizing assembly 3 to generate relative movement with the filter assembly 2, and pulverizing the residue intercepted by the filter assembly 2.

[0069] In this embodiment, the pulverizing component 3 includes a first pulverizing element 31 and a second pulverizing element 32; the first power output terminal 411 of the driving device 4 is connected to the first pulverizing element 31, and the second power output terminal 412 of the driving device 4 is connected to the second pulverizing element 32. Through this arrangement, the different components of the pulverizing component 3 can generate relative movements, using these relative movements to pulverize the residue intercepted by the filter component 2. This allows the pulverized residue to pass through the filter component 2 with the water flow and exit the filter chamber 1, thereby achieving a self-cleaning and maintenance-free effect for the filter component 2. Simultaneously, through this arrangement, even when the different components of the pulverizing component 3 are rotating, relative movements can still occur between the pulverizing element and the filter component 2, achieving the effect of pulverizing residue.

[0070] In this embodiment, the filter assembly 2 includes a filter element 20 composed of a cylindrical filter screen, which divides the filter chamber 1 into a filtered chamber 102 on the outer periphery and a chamber to be filtered 101 on the inner periphery; the pulverizing assembly 3 is disposed in the chamber to be filtered 101, so as to directly contact the residue filtered and intercepted by the filter element 20, so that the filter element 20 and the pulverizing assembly 30 rotate relative to each other around the axis, and the intercepted residue is pulverized by the relative rotational force.

[0071] In this embodiment, the pulverizer 30 is any or a combination of existing grinding structures such as blade structure, grinding disc structure, roller structure, grinding sleeve structure, etc. The rotational force of the pulverizer 30 is used to pulverize the residue. The pulverizer 30 is placed in the filter chamber 101 to directly pulverize the residue intercepted by the filter assembly 2, so that the pulverized residue is discharged with the drainage.

[0072] In this embodiment, the first crushing component 31 and the second crushing component 32 of the crushing assembly 3 are any one or a combination of blade structure, grinding disc structure, roller structure, and grinding sleeve structure, so as to utilize the relative rotation of the two around the axis to generate a crushing force between them to crush the intercepted residue.

[0073] In this embodiment, the shaft of the first crusher 31 is connected to the first power output end 411 to drive the first crusher 31 to generate a first rotation; the shaft of the second crusher 32 is connected to the second power output end 412 to drive the second crusher 32 to generate a second rotation; wherein, at least part of the direction of rotation and speed of the first rotation and the second rotation are different. Optionally, the rotation directions of the first rotation and the second rotation are set to be different to increase the grinding force between the two crushers 30 by using opposite rotations, thereby improving the crushing effect on the residue.

[0074] Example 4

[0075] This embodiment, based on embodiments one to three above, also has the following technical features:

[0076] like Figures 1 to 5 As shown, in this embodiment, the first power output end 411 and the second power output end 412 of the driving device 4 output power in the same or different directions and at the same or different speeds, so as to drive different components of the filter structure to rotate at different speeds, thereby achieving the effect of crushing residues by using differential rotation.

[0077] In this embodiment, to achieve the above-mentioned effect, the driving device 4 can be any existing driving structure that can achieve the above objective. Specifically, it can be as follows:

[0078] Yes, such as Figure 3 As shown, in this embodiment, the driving device 4 includes a dual-rotor motor 42; the dual-rotor motor 42 has a first rotor 421 and a second rotor 422 that can be driven to rotate independently, the first rotor 421 is connected to a first output shaft to form a first power output end 411, and the second rotor 422 is connected to a second output shaft to form a second power output end 412.

[0079] It's alright, such as Figure 2 As shown, in this embodiment, the driving device 4 includes a drive motor 43 and a transmission device 44. The transmission device 44 has an input section 441, a first output section 442, and a second output section 443. The transmission device 44 has a first transmission structure, through which the input section 441 is connected to the first output section 442, and through a second transmission structure, it is connected to the second output section 443, for transmitting different forms of power to different output sections.
