[0001] This application belongs to the field of cleaning technology, and more specifically, relates to a filter element of a cleaning machine and a cleaning machine. Background Technology

[0002] The washing water in the washing machine needs to be circulated into the washing chamber. During the circulation process, the washing water needs to be filtered to prevent clogging of the washing pump and washing components. After washing is completed, the washing water needs to be discharged to the outside through a drain pump. During the discharge process, filtration is usually required to prevent clogging of the drain pump and drain pipes.

[0003] In related technologies, different filtration devices are used for filtration during the washing water circulation process and the discharge process, resulting in low integration. Utility Model Content

[0004] The purpose of this application is to provide a filter element for a cleaning machine and a cleaning machine to solve the technical problem of low integration.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a filter element for a cleaning machine is provided. The cleaning machine includes a body and a pump assembly. The body includes a cleaning chamber, and the pump assembly includes a washing pump and a drain pump. The filter element includes a filter channel, an inlet hole communicating with the filter channel, a first filter screen, and a second filter screen. The first filter screen includes a plurality of first filter holes, and the second filter screen includes a plurality of second filter holes. The inlet hole is adapted to communicate with the cleaning chamber, the first filter holes are adapted to communicate with the inlet of the washing pump, and the second filter holes are adapted to communicate with the inlet of the drain pump. The aperture of the first filter holes is smaller than the aperture of the second filter holes.

[0007] Through the above technical solution, the filter element provided in this application can filter the washing water entering the washing pump using a first filter hole with a relatively small pore size, and can also filter the washing water entering the sewage pump using a second filter hole with a relatively large pore size. The filter element provided in this application can filter the washing water entering the washing pump and the sewage pump separately, which can improve the integration.

[0008] Therefore, the filter provided in this application can solve the technical problem of low integration.

[0009] In some embodiments, the first filter and / or the second filter are arranged in an arc shape. An arc shape for the first filter increases its surface area, and an arc shape for the second filter increases its surface area, thus improving the filtration effect.

[0010] In some embodiments, the first filter screen and / or the second filter screen are flat. This helps to improve the uniformity of force distribution across the first filter screen and / or the second filter screen.

[0011] In some implementations, the first and second filters are at an angle. This allows the first and second filters to be connected to the inlets of different pumps; that is, the first filter hole can be connected to the inlet of the washing pump, and the second filter hole can be connected to the inlet of the sewage pump, which helps to improve integration.

[0012] In some embodiments, the filter element further includes a filter tube and a mounting component. The cavity of the filter tube includes a filter channel. The mounting component is connected to the filter tube. The filter element is adapted to be installed at the bottom of the cleaning chamber by the mounting component. A first filter screen and a second filter screen are disposed on the tube wall of the filter tube. The water inlet of the filter element is disposed on the filter tube.

[0013] In this way, the filter element provided in this application can be installed at the bottom of the cleaning chamber, and the filter element's filter channel, water inlet, first filter screen and second filter screen can be integrated on the filter tube, which is beneficial to improving the integration.

[0014] In some implementations, the mounting component has a water collection tank, and the water inlet of the filter element is connected to the water collection tank. In this way, the water collection tank can guide the washing water to the filter channel, which helps to improve the filtration efficiency.

[0015] In some embodiments, the filter element further includes a positioning part disposed on the mounting component, adapted to engage with the body, and mounted on the bottom of the mounting component. In this way, the filter element provided in this application can be conveniently and stably installed at the bottom of the cleaning chamber.

[0016] In some embodiments, the filter element further includes a handle portion disposed on the mounting component, the handle portion being connected to the upper part of the mounting component.

[0017] This makes the handle easy to grip with a hand or clamping tool, thus facilitating the handling of the filter element.

[0018] Secondly, this application provides a cleaning machine that includes the filter element of any of the above embodiments. The cleaning machine provided by this application has the same or similar technical effects as the filter element of any of the above embodiments, and will not be described in detail here.

[0019] In some embodiments, the cleaning machine provided in this application further includes a filter screen, which abuts between the machine body and the filter element.

[0020] In some embodiments, the pump assembly further includes a connecting housing connected to both the washing pump and the sewage pump. The connecting housing has a connecting cavity and a first connecting hole and a second connecting hole communicating with the connecting cavity. The first connecting hole communicates with the inlet of the washing pump, and the second connecting hole communicates with the inlet of the sewage pump. A filter element is installed in the connecting cavity, with the first connecting hole communicating with a first filter screen and the second connecting hole communicating with a second filter screen.

[0037] Please see Figure 1 and Figure 2This application provides a cleaning machine 100, which includes a body 110 and a cleaning chamber 111. The bottom wall of the cleaning chamber 111 is provided with a circulation inlet 112 and a circulation outlet 1131. The cleaning machine 100 uses washing water to circulate in and out of the circulation inlet 112 and the circulation outlet 1131 to clean items to be cleaned in the cleaning chamber 111 of the body 110. The items to be cleaned can be clothes, tableware, baby bottles, etc.

[0038] Optionally, the cleaning machine 100 provided in this application embodiment can be a washing machine, dishwasher, baby bottle cleaning machine 100, etc.

[0039] Please see Figure 3 The cleaning machine 100 provided in this application embodiment includes a pump assembly 20, which is installed on the side of the machine body 110 away from the cleaning chamber 111 (e.g., below).

[0040] Optionally, the pump assembly 20 includes a washing pump 21. The washing water in the washing machine 100 needs to be circulated into the washing chamber 111 by the washing pump 21. During the circulation process, the washing water needs to be filtered to prevent clogging of the washing pump 21 and the washing assembly (not shown in the figure). The washing pump 21 has a washing outlet 211 that communicates with the circulation inlet 112. The washing water entering the washing pump 21 can return to the washing chamber 111 through the washing outlet 211 and the circulation inlet 112.

[0041] Optionally, the pump assembly 20 includes a sewage pump 22. After washing, the washing water needs to be discharged to the outside through the sewage pump 22. During the discharge process, filtration is usually required to prevent clogging of the sewage pump 22 and the sewage pipe (not shown in the figure). The washing water entering the sewage pump 22 can be discharged to the outside through the sewage outlet 221 of the sewage pump 22.

[0042] The inventors discovered that in related technologies, different filtration devices are used for filtration during the washing water circulation process and the discharge process, resulting in low integration.

[0043] To resolve the aforementioned technical issues, please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The cleaning chamber 111 is provided with a mounting groove 113, and the circulation outlet 1131 is disposed in the mounting groove 113. The cleaning machine 100 provided in this application embodiment also includes a filter element 10, which is installed in the mounting groove 113, that is, the filter element 10 is installed at the bottom of the cleaning chamber 111 through the mounting groove 113.

[0044] The filter element 10 can filter the washing water that enters the washing pump 21 and the sewage pump 22 from the circulation outlet 1131 in the washing chamber 111.

[0045] Optionally, the mounting groove 113 is located at the bottom of the cleaning chamber 111, and the circulation outlet 1131 is located on the bottom wall of the mounting groove 113.

[0046] Please see Figure 6 The filter element 10 includes a filter channel 101 and an inlet 102 communicating with the filter channel 101. The inlet 102 can communicate with the cleaning chamber 111. In this way, the washing water in the cleaning chamber 111 can first enter the inlet 102 of the filter channel 101 through the circulation outlet 1131, and then the washing water is filtered by the filter channel 101 and enters the washing pump 21 and the sewage pump 22.

[0047] Optionally, the filter element 10 includes a first filter screen 103 communicating with the filter channel 101. The first filter screen 103 includes a first filter hole 1031 communicating with the filter channel 101 and can communicate with the inlet of the washing pump 21. In this way, the filter element 10 can filter the washing water entering the washing pump 21 from the circulation outlet 1131 in the washing chamber 111.

[0048] Optionally, the first filter screen 103 is arranged in an arc shape, which can increase the area of ​​the first filter screen 103 and thus increase the number of first filter holes 1031, which is beneficial to improving the filtration effect.

[0049] Optionally, the first filter screen 103 is flat, which helps to improve the uniformity of force distribution throughout the first filter screen 103 and facilitates manufacturing.

[0050] Optionally, the filter element 10 is connected to the filter channel 101 via a second filter screen 104. The second filter screen 104 includes a second filter hole 1041, which is connected to the filter channel 101 and can also be connected to the inlet of the sewage pump 22. In this way, the filter element 10 can use the second filter screen 104 to filter the washing water entering the sewage pump 22 from the circulation outlet 1131 in the cleaning chamber 111.

[0051] Optionally, the second filter screen 104 is arranged in an arc shape, which can increase the area of ​​the second filter screen 104, thereby increasing the number of second filter holes 1041, which is beneficial to improving the filtration effect.

[0052] Optionally, the second filter screen 104 is flat, which helps to improve the uniformity of force distribution throughout the second filter screen 104 and facilitates manufacturing.

[0053] Optionally, the aperture of the first filter hole 1031 is smaller than the aperture of the second filter hole 1041. This allows the filter element 10 to filter out impurities in the washing water entering the washing pump 21 through the first filter screen 103, preventing clogging of the washing pump 21 and the washing components. Furthermore, the second filter hole 1041 of the filter element 10 allows dirt to pass through, so that the washing wastewater containing dirt is discharged to the outside through the drain pump 22.

[0054] It is understood that the filter element 10 provided in this application embodiment can filter the washing water entering the washing pump 21 using the first filter hole 1031 with a relatively small pore size, and can also filter the washing water entering the sewage pump 22 using the second filter hole 1041 with a relatively large pore size, so that some dirt can be discharged with the washing wastewater. That is, the filter element 10 provided in this application embodiment can filter the washing water entering the washing pump 21 and the sewage pump 22 respectively, which can improve the integration.

[0055] Therefore, the filter element 10 provided in this application embodiment can solve the technical problem of low integration.

[0056] Please see Figure 3 and Figure 6 In some embodiments, the first filter hole 1031 and the second filter hole 1041 are arranged at an angle. This facilitates the connection of the first filter hole 1031 and the second filter hole 1041 to the inlet of different pumps, that is, the first filter hole 1031 can be connected to the inlet of the washing pump 21, and the second filter hole 1041 can be connected to the inlet of the sewage pump 22.

[0057] Therefore, the filter element 10 can filter the washing water entering the washing pump 21 and the sewage pump 22 respectively, thereby improving the integration.

[0058] For example, the first filter hole 1031 and the second filter hole 1041 are offset circumferentially along the filter channel 101.

[0059] For example, the first filter hole 1031 and the second filter hole 1041 are arranged circumferentially along the filter channel 101.

[0060] In this way, when the first filter hole 1031 and the second filter hole 1041 are spaced apart circumferentially along the filter channel 101, the first filter hole 1031 and the second filter hole 1041 can be positioned axially (e.g., along the filter channel 101) in the filter channel 101. Figure 3 Located in the same position as the filter channel 101 in the Z direction, it is advantageous to arrange the first filter hole 1031 and the second filter hole 1041.

[0061] Optionally, the axial direction of the first filter hole 1031 intersects the axial direction of the second filter hole 1041.

[0062] Furthermore, when the axial direction of the first filter hole 1031 intersects the axial direction of the second filter hole 1041, the axial direction of the washing pump 21 and the axial direction of the sewage pump 22 can also intersect. That is, the washing pump 21 has a first axis 001, the sewage pump 22 has a second axis 002, and the extending direction of the first axis 001 (e.g., Figure 3 The X direction in the middle can intersect with the extension direction of the second axis 002 (e.g., Figure 3 (in the Y direction). This helps to reduce the size of the pump assembly 20, thereby reducing the space occupied by the pump assembly 20.

[0063] Optionally, please refer to Figure 3 The axial direction of the first filter hole 1031 is perpendicular to the axial direction of the second filter hole 1041.

[0064] Please refer to the following: Figure 6 , Figure 7 and Figure 8 In some embodiments, at least a portion of the second filter hole 1041 is located on the side of the first filter hole 1031 away from the inlet 102.

[0065] It is understandable that washing wastewater is more likely to concentrate at the end of the filter channel 101 away from the inlet 102. The filter element 10 provided in this application embodiment has at least a portion of the second filter hole 1041 disposed on the side of the first filter hole 1031 away from the inlet 102, which can filter the washing wastewater and facilitate the timely discharge of the washing wastewater, thereby avoiding the clogging of the first filter hole 1031 by dirt in the washing wastewater to a certain extent.

[0066] Please continue reading. Figure 6 In some embodiments, the filter element 10 further includes a filter tube 1, the cavity of which includes a filter channel 101, a first filter screen 103 and a second filter screen 104 disposed on the wall of the filter tube 1, and an inlet 102 disposed on the filter tube 1. In this way, the filter channel 101, the inlet 102, the first filter screen 103 and the second filter screen 104 of the filter element 10 can be integrated on the filter tube 1, which is beneficial to improving the integration.

[0067] For example, the water inlet 102 is located at one end of the filter tube 1, and the other end of the filter tube 1 is closed. In this way, the axis of the filter channel 101 is the axis of the filter tube 1, which facilitates processing.

[0068] Optionally, the filter element 10 also includes an installation component 2, which is connected to the filter tube 1. The filter element 10 can be installed at the bottom of the cleaning chamber 111 through the installation component 2 for easy installation.

[0069] Optionally, the mounting component 2 is provided with a water collection tank 201, and the water inlet 102 is connected to the water collection tank 201. In this way, the water collection tank 201 can guide the washing water to the filter channel 101, which helps to improve the filtration efficiency.

[0070] For example, the water inlet 102 is provided on the bottom wall of the water collection tank 201.

[0071] Please see Figure 6 and Figure 7 The filter element 10 also includes a handheld part 3 disposed on the mounting component 2. The handheld part 3 is easy to be held by a human hand or a clamping tool, thereby facilitating the handling and placement of the filter element 10.

[0072] Optionally, the handheld part 3 is located on one side of the mounting part 2 along the axial direction of the filter channel 101.

[0073] For example, the handheld part 3 is connected to the upper part of the mounting part 2.

[0074] Optionally, the handheld part 3 and the first filter hole 1031 are located on different sides of the mounting part 2.

[0075] Optionally, the farthest surface of the handle 3 away from the first filter hole 1031 is not higher than the farthest surface of the mounting component 2 away from the first filter hole 1031. Optionally, the top surface of the handle 3 is not higher than the top surface of the mounting component 2. This can prevent the handle 3 from being scratched or bumped during installation, transportation, or use, which helps to improve safety.

[0076] Please refer to the following: Figure 3 , Figure 7 , Figure 8 and Figure 9 In some embodiments, the filter element 10 further includes a positioning part 4, which is disposed on the mounting component 2 and is used to engage with the body 110. In this way, the filter element 10 provided in this application embodiment can be conveniently and stably installed on the inner wall of the cleaning chamber 111.

[0077] Optionally, the positioning part 4 is installed at the bottom of the mounting part 2. That is, the filter element 10 can be installed on the bottom wall of the cleaning chamber 111.

[0078] Optionally, please refer to Figure 3 The bottom wall of the mounting slot 113 of the body 110 is provided with a snap-fit ​​part 1132, which is used to snap-fit ​​with the positioning part 4.

[0079] Optionally, please refer to Figure 9The positioning part 4 protrudes from the surface of the mounting component 2, which facilitates the engagement of the positioning part 4 and the snap-fit ​​member 1132. In addition, compared to the positioning part 4 being recessed in the surface of the mounting component 2, the positioning part 4 protruding from the surface of the mounting component 2 can help reduce the size of the mounting component 2.

[0080] In some embodiments, the first filter hole 1031 and the second filter hole 1041 are disposed on one side of the mounting component 2, and the positioning part 4 is disposed on the side of the mounting component 2 facing the first filter hole 1031. In this way, while the filter element 10 is being installed onto the filter tube 1, the positioning part 4 can be snapped into the snap-fit ​​part 1132, facilitating installation. Furthermore, the filter element 10 provided in this embodiment can be positioned using the positioning part 4, ensuring that the first filter screen 103 and the second filter screen 104 are installed in the correct positions.

[0081] Please see Figure 8 Optionally, the handle 3 and the positioning part 4 are located on different sides of the mounting component 2. This facilitates the positioning and installation of the filter element 10 by clamping the handle 3.

[0082] Optionally, the positioning part 4 is provided with a cavity 401, which can save materials. In addition, the positioning part 4 with a cavity 401 is easier to deform, making it easier for the positioning part 4 and the snap-fit ​​part to snap together.

[0083] Furthermore, the cavity 401 is provided in the positioning part 4, and the depth of the cavity 401 can be increased by utilizing the size of the positioning part 4, which is beneficial for saving materials and reducing the overall size of the filter element 10.

[0084] The cleaning machine 100 provided in this application includes the filter element 10 of any of the above embodiments. The cleaning machine 100 provided in this application has the same or similar technical effects as the filter element 10 of any of the above embodiments, and will not be described again here.

[0085] In some embodiments, the cleaning machine 100 provided in this application also includes a filter screen (not shown in the figure), which abuts between the machine body 110 and the filter element 10.

[0086] Understandably, the filter screen can further filter the water filtered by the filter element 10, which helps to improve the filtration effect.

[0087] It is understandable that the filter screen can be configured with a first mesh corresponding to the first filter hole 1031, and can also be configured with a second mesh corresponding to the second filter hole 1041.

[0088] Optionally, the aperture of the first mesh is smaller than the aperture of the second mesh.

[0089] In some embodiments, the pump assembly 20 further includes a connecting housing 23, which is connected to both the washing pump 21 and the sewage pump 22. Optionally, the connecting housing 23 can be integrally formed with the housings of the washing pump 21 and the sewage pump 22 for ease of manufacturing. For example, the connecting housing 23 can be manufactured by casting with the housings of the washing pump 21 and the sewage pump 22.

[0090] Optionally, the connecting shell 23 is provided with a connecting cavity 231 and a first connecting hole 233 and a second connecting hole communicating with the connecting cavity 231.

The filter element 10 is installed in the connecting cavity 231, the first connecting hole 233 is connected to the first filter hole 1031, and the second connecting hole is connected to the second filter hole 1041.

[0091] In this way, the connecting shell 23 can be adapted to the filter element 10, thereby enabling the filter element 10 to achieve the filtration effect.

[0092] Optionally, the communicating shell 23 has a connecting hole 232, through which the filter element 10 can mate with the communicating shell 23. For example, the filter tube 1 of the filter element 10 can be inserted into the communicating cavity 231 through the connecting hole 232.

[0093] Optionally, the first connecting hole 233 is sealed to the first filter hole 1031, and the second connecting hole is sealed to the second filter hole 1041. This prevents washing water leakage.
