Technical Field

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

[0002] The cleaning machine uses cleaning fluid in the cleaning chamber to clean the items. The cleaning fluid can be discharged through the water outlet at the bottom of the cleaning chamber to remove wastewater or for recirculation. The water outlet at the bottom of the cleaning chamber is usually equipped with a filter to filter the cleaning fluid.

[0003] In related technologies, filter components are installed and fixed by means of snap-fit ​​connections, threaded connections, etc., which are inconvenient for disassembly and cleaning. Utility Model Content

[0004] The purpose of this application is to provide a cleaning machine and its filter assembly to solve the problem that filter components are inconvenient to disassemble and clean.

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

[0006] In a first aspect, a filter assembly for a cleaning machine is provided. The cleaning machine has a cleaning chamber and a water outlet communicating with the cleaning chamber. The water outlet is disposed on the bottom wall of the cleaning chamber. The filter assembly includes a mounting plate and a filter screen. The mounting plate is adapted to be installed at the water outlet and is used for interference fit with the wall of the water outlet. The mounting plate is provided with a through hole, and the filter screen is disposed at the through hole and fixedly connected to the mounting plate.

[0007] Through the above technical solution, the filter assembly provided in this application fixes the filter screen to the mounting plate, and the mounting plate is installed at the water outlet, so that it can be installed on the bottom wall of the cleaning chamber, allowing the filter screen to filter the cleaning liquid flowing through the water outlet. In addition, the mounting plate and the wall of the water outlet of the cleaning chamber are interference-fitted, eliminating the need for fixation by other structures, thus facilitating disassembly and assembly, and making it easier to clean impurities on the filter screen after disassembly.

[0008] Therefore, the filter assembly of the cleaning machine provided in this application can solve the problem of inconvenient disassembly and cleaning of filter components.

[0009] In some implementations, the filter screen satisfies at least one of the following conditions:

[0010] The filter screen is made of nylon.

[0011] The filter screen and mounting plate are integrally molded;

[0012] The mesh count of the filter screen is greater than or equal to 50 and less than or equal to 500;

[0013] The thickness of the filter screen is greater than or equal to 0.1 mm and less than or equal to 0.3 mm.

[0014] Through the above technical solution, the filter screen is made of nylon, which can have good corrosion resistance and high temperature resistance.

[0015] Alternatively, compared to fixing the filter screen and mounting plate together in other ways, the filter screen and mounting plate are integrally molded, which helps to improve the overall strength of the filter assembly.

[0016] Optionally, the mesh size of the filter screen is greater than or equal to 50 and less than or equal to 500, which is beneficial to improving the filtration effect on fine impurities.

[0017] Optionally, the thickness of the filter screen is greater than or equal to 0.1 mm and less than or equal to 0.3 mm, which helps to reduce manufacturing costs while meeting the filtration effect.

[0018] In some implementations, the mounting plate is made of plastic. This prevents the mounting plate from rusting and provides good corrosion resistance.

[0019] In some embodiments, the filter assembly further includes a sealing ring disposed on the outer peripheral wall of the mounting plate and surrounding the mounting plate, the mounting plate being used for an interference fit between the sealing ring and the wall of the outlet hole.

[0020] In this way, the sealing ring can seal the installation seam between the mounting plate and the wall of the water outlet, which helps to prevent the cleaning fluid from leaking at the installation seam and has a good waterproof effect.

[0021] In some embodiments, the outer peripheral wall of the mounting plate is provided with a sealing groove, into which the sealing ring is embedded. This arrangement increases the sealing path and improves the sealing effect of the sealing ring.

[0022] In some embodiments, the filter assembly further includes at least one limiting plate connected to the edge of the mounting plate and located on one side of the mounting plate in the thickness direction, the limiting plate being used to overlap with the bottom wall of the cleaning chamber.

[0023] In this way, the filter assembly can be limited by the limiting plate, which can prevent it from falling off the mounting hole.

[0024] In some implementations, the mounting plate is provided with a water collection tank, and the through-hole is located at the lowest point of the water collection tank. In this way, the cleaning fluid can flow to the filter screen at the through-hole, which helps to improve the filtration effect.

[0025] In some embodiments, the depth of at least a portion of the water collection tank gradually increases along the edge of the mounting plate in the direction of the through hole.

[0026] In this way, the cleaning fluid can flow smoothly to the filter screen at the through holes, allowing impurities to accumulate preferentially on the filter screen, thereby improving the filtration effect.

[0027] In some embodiments, the mounting plate includes support ribs, the filter screen is connected to the support ribs, the support ribs are disposed in the through holes and connected to the hole walls of the through holes, the through holes include multiple non-communicating hole areas, the hole areas are formed between the support ribs and the hole walls of the through holes.

[0028] In this way, the support ribs can support the filter screen, which can improve the strength of the filter screen without affecting the filtration effect.

[0029] In some embodiments, the mounting plate also includes a handheld plate connected to the support ribs. This allows the filter assembly provided in this application embodiment to be easily handled and disassembled via the handheld plate.

[0030] Secondly, this application provides a cleaning machine, which includes a filter assembly according to any of the above embodiments. The cleaning machine has a cleaning chamber and a water outlet communicating with the cleaning chamber. The water outlet is disposed on the bottom wall of the cleaning chamber, and a mounting plate is installed at the water outlet and is interference-fitted with the wall of the water outlet.

[0031] The cleaning machine provided in this application has the same or similar technical effects as the filter components of any of the above embodiments, and will not be described again here.

[0032] In some embodiments, the water outlet is located at the lowest point of the cleaning chamber, and / or the upper surface of the filter screen is lower than the lowest point of the cleaning chamber.

[0033] In this way, the water in the cleaning chamber can flow to the outlet and be filtered by the filter screen, which helps to prevent the cleaning fluid and its impurities from accumulating in other parts of the cleaning chamber.

[0034] In some embodiments, the cleaning machine provided in this application has a flat heating chamber located below the filter screen and communicating with the water outlet; the cleaning machine includes a heater, the heater includes a heating plate, the heating plate is disposed on the bottom wall of the heating chamber, and the orthographic projection of the filter screen in the bottom wall surface of the heating chamber overlaps with the orthographic projection of the heating plate in the bottom wall surface of the heating chamber.

[0035] In this way, the cleaning machine provided in this application can use a heater to heat the cleaning liquid that has been filtered through the filter screen, which is beneficial to improving the cleaning effect.

[0036] In some implementations, the ratio of the heating plate area to the filter screen area is greater than or equal to 0.8. This increases the heating area of ​​the heating plate, which helps to improve heating efficiency.

[0037] In some embodiments, the cleaning machine has a water outlet channel located on one side of the heating chamber and communicating with it, with the bottom wall of the water outlet channel being lower than the upper surface of the heating plate. This allows the cleaning fluid in the heating chamber to easily flow into the water outlet channel, improving the circulation efficiency of the cleaning fluid. Attached Figure Description

The sewage pump is not the focus of protection in this application and is not limited here.

[0057] In some embodiments, please refer to Figure 2 and Figure 3 , Figure 2 For along Figure 1 The cross-sectional view of the AA line shows that the cleaning machine 1000 provided in this application embodiment includes a heater 300, which is disposed below the cleaning chamber 100. A heating chamber 1001 is formed between the heater 300 and the cleaning chamber 100, and the water outlet 103 is connected to the heating chamber 1001.

[0058] In this way, the cleaning machine 1000 provided in this application embodiment can use the heater 300 to heat the cleaning fluid flowing through the heating chamber 1001. This can heat the cleaning fluid entering the cleaning chamber 101 from the water inlet 102, which is beneficial to improving the cleaning effect.

[0059] Optionally, the cleaning machine 1000 provided in this embodiment includes a filter assembly 200, which is installed at the water outlet 103, and the heater 300 can be disposed directly below the filter assembly 200. In this way, the filter assembly 200 can filter the cleaning liquid flowing out of the water outlet 103, and the filtered cleaning liquid can flow directly onto the heater 300 for heating. At this point, the cleaning liquid is evenly dispersed, which helps to improve the heating effect.

[0060] In some embodiments, please continue reading Figure 2 and combined Figure 3 and Figure 4 , Figure 3 This is a top view of the heater 300 in the heating chamber 1001 provided in an embodiment of this application. Figure 4 This is one of the three-dimensional structural schematic diagrams of the filter assembly provided in the embodiments of this application. The filter assembly 200 provided in the embodiments of this application includes a mounting plate 10 and a filter screen 20. The mounting plate 10 is installed at the water outlet 103, and the mounting plate 10 is interference-fitted with the wall of the water outlet 103. The mounting plate 10 is provided with a through hole, and the filter screen 20 is disposed at the through hole and fixedly connected to the mounting plate 10.

[0061] Through the above technical solution, the filter assembly 200 provided in this application embodiment fixes the filter screen 20 to the mounting plate 10, and the mounting plate 10 is installed at the water outlet 103, so that it can be installed on the bottom wall of the cleaning chamber 101, allowing the filter screen 20 to filter the cleaning liquid flowing through the water outlet 103. In addition, the mounting plate 10 and the wall of the water outlet 103 of the cleaning chamber 101 are interference-fitted, requiring no other structure for fixation, thus facilitating disassembly and assembly, and making it convenient to clean impurities on the filter screen 20 after disassembly.

[0062] Therefore, the filter assembly 200 of the cleaning machine 1000 provided in this application embodiment can solve the problem of inconvenient disassembly and cleaning of filter components.

[0063] Optionally, the water outlet 103 is located at the lowest point of the cleaning chamber 101.

[0064] Optionally, the upper surface of the filter screen 20 is lower than the lowest point of the cleaning chamber 101.

[0065] Optionally, the water outlet 103 is located at the lowest point of the cleaning chamber 101, and the upper surface of the filter screen 20 is lower than the lowest point of the cleaning chamber 101.

[0066] In this way, the water in the cleaning chamber 101 can flow to the water outlet 103 and can be filtered by the filter screen 20, which helps to prevent the cleaning fluid and its impurities from accumulating in other parts of the cleaning chamber 101.

[0067] Please continue reading. Figure 2 , Figure 3 and Figure 4Optionally, the heating chamber 1001 is flat, which facilitates the uniform dispersion of the cleaning fluid within the heating chamber 1001, thereby improving the heating effect of the heater 300 on the cleaning fluid. Furthermore, the heater 300 includes a heating plate 310, which is disposed on the bottom wall of the heating chamber 1001; for example, the heating plate 310 can be part of the bottom wall of the heating chamber 1001. It is understood that the flat heating chamber 1001 allows the heating plate 310 to be close to the filter screen 20, enabling heating of the filter screen 20 and melting of grease on the filter screen 20, thus preventing grease from solidifying on the filter screen 20.

[0068] Optionally, the heating chamber 1001 is located below the filter screen 20, and the orthographic projection of the filter screen 20 in the bottom wall of the heating chamber 1001 overlaps with the orthographic projection of the heating plate 310 in the bottom wall of the heating chamber 1001. This allows the filtered cleaning liquid to be directly sprayed onto the heating plate 310, which is beneficial to improving the heating effect.

[0069] For example, the orthographic projection of the filter screen 20 in the bottom wall of the heating chamber 1001 is located within the orthographic projection of the heating plate 310 in the bottom wall of the heating chamber 1001.

[0070] For example, the orthographic projection of the heating plate 310 in the bottom wall of the heating cavity 1001 is located within the orthographic projection of the filter screen 20 in the bottom wall of the heating cavity 1001.

[0071] Please continue reading. Figure 2 , Figure 3 and Figure 4 In some embodiments, the ratio of the area of ​​the heating plate 310 to the area of ​​the filter screen 20 is greater than or equal to 0.8. This increases the heating area of ​​the heating plate 310, which is beneficial to improving heating efficiency.

[0072] Optionally, the ratio of the area of ​​the heating plate 310 to the area of ​​the filter screen 20 is greater than or equal to 0.9.

[0075] Please continue reading. Figure 2 , Figure 3 and Figure 4In some embodiments, the cleaning machine 1000 has a water outlet channel 1002, which is located on one side of the heating chamber 1001 and communicates with it. The bottom wall of the water outlet channel 1002 is lower than the upper surface of the heating plate 310. This allows the cleaning fluid in the heating chamber 1001 to easily flow to the water outlet channel 1002, improving the circulation efficiency of the cleaning fluid. It is understood that with an improved heating effect of the heater 300, the cleaning fluid can reach the preset temperature more quickly, further improving the cleaning effect.

[0076] Optionally, the water outlet channel 1002 can be provided with a drain port 1004 and a circulation port 1003. The drain port 1004 can be connected to a drain pump so that the washing liquid after washing can be discharged from the drain port 1004. The circulation port 1003 can be connected to a washing circulation pump so that the washing circulation pump can pump the washing liquid in the water outlet channel 1002 into the water inlet 102 so that the washing liquid can circulate into the washing chamber 101.

[0077] In some embodiments, the filter screen 20 is a nylon filter screen, which gives the filter screen 20 good corrosion resistance and high temperature resistance.

[0078] Optionally, the filter screen 20 is integrally formed with the mounting plate 10.

[0079] Optionally, the filter screen 20 is welded to the mounting plate 10.

[0080] Optionally, the filter screen 20 is fused to the mounting plate 10.

[0081] It is understandable that, compared to the filter screen 20 and the mounting plate 10 being fixedly connected by other means, the filter screen 20 and the mounting plate 10 are integrally formed, which is beneficial to improving the overall strength of the filter assembly 200.

[0082] In some embodiments, the mesh count of the filter screen 20 is greater than or equal to 50 and less than or equal to 500, which helps to improve the filtration effect on fine impurities.

[0094] In some embodiments, the mounting plate 10 is a plastic plate. This prevents the mounting plate 10 from rusting and provides good corrosion resistance.

[0095] In some embodiments, please continue reading Figure 4 and combined Figure 5 , Figure 5 For along Figure 4 The cross-sectional view of the BB line shows that the filter assembly 200 also includes a sealing ring 40. The sealing ring 40 is disposed on the outer peripheral wall of the mounting plate 10 and surrounds the mounting plate 10. The mounting plate 10 is used for interference fit with the wall of the outlet hole 103 through the sealing ring 40.

[0096] In this way, the sealing ring 40 can seal the installation seam between the mounting plate 10 and the hole wall of the water outlet 103, which helps to prevent the cleaning fluid from leaking at the installation seam and has a good waterproof effect.

[0097] Alternatively, please continue reading Figure 4 and Figure 5 and combined Figure 6 , Figure 6 The second schematic diagram of the three-dimensional structure of the filter assembly provided in the embodiment of this application shows that the outer peripheral wall of the mounting plate 10 is provided with a sealing groove 11, and the sealing ring 40 is embedded in the sealing groove 11. In this way, the contact area between the sealing ring 40 and the mounting plate 10 is increased, which can increase the sealing path and improve the sealing effect of the sealing ring 40.

[0098] In some embodiments, please continue reading Figure 4 and Figure 5 The filter assembly 200 provided in this application embodiment also includes at least one limiting plate 30. The limiting plate 30 is connected to the edge of the mounting plate 10 and is located on one side in the thickness direction of the mounting plate 10. The limiting plate 30 is used to overlap with the bottom wall of the cleaning chamber 101.

[0099] In this way, the filter assembly 200 provided in this application embodiment can be limited by the limiting plate 30, which can prevent it from falling off from the mounting hole.

[0100] Optionally, the filter assembly 200 provided in this application embodiment may include a plurality of limiting plates 30. For example, there are two limiting plates 30, one of which is a first limiting plate 31 and the other is a second limiting plate 32, wherein the first limiting plate 31 and the second limiting plate 32 are arranged opposite to each other.

[0101] It is understood that, in addition to using the limiting plate 30 to limit the position of the filter assembly 200 provided in this application embodiment, the mounting plate 10 can also be removed through the limiting plate 30, thereby facilitating the disassembly and assembly of the mounting plate 10.

[0102] In some embodiments, please refer to Figure 5 The mounting plate 10 is equipped with a water collection tank, and the through hole is located at the lowest point of the water collection tank. In this way, the cleaning fluid can flow to the filter screen 20 at the through hole, which helps to improve the filtration effect.

[0103] Optionally, the bottom of the water collection tank can be a concave conical or arc-shaped structure.

[0104] Optionally, at least a portion of the depth of the water collection tank gradually increases along the edge of the mounting plate 10 towards the through hole. This allows the cleaning fluid to flow smoothly to the filter screen 20 at the through hole, enabling impurities to preferentially accumulate on the filter screen 20, thereby improving the filtration effect.

[0105] It is understandable that the bottom of the water collection tank is provided with an inclined guide surface 12, and the height of the guide surface 12 gradually decreases along the edge of the mounting plate 10 towards the through hole.

[0106] In some embodiments, the mounting plate 10 includes a support rib 50, the filter screen 20 is connected to the support rib 50, the support rib 50 is disposed in a through hole and connected to the hole wall of the through hole, the through hole includes a plurality of non-communicating hole areas, the hole areas being formed between the support rib 50 and the hole wall of the through hole.

[0107] In this way, the support rib 50 can support the filter screen 20, which can improve the strength of the filter screen 20 without affecting the filtration effect of the filter screen 20.

[0108] It is understandable that the filter screen 20 can also be divided into multiple filtration areas, with each filtration area corresponding to a different pore area.

[0109] For example, the different filtration zones of the filter screen 20 have different mesh sizes. In this way, the impurities accumulated on the filter screen 20 are unevenly distributed, and even if one filtration zone is blocked, other filtration zones can still perform filtration, thereby improving the filtration effect.

[0110] In some embodiments, the mounting plate 10 further includes a handheld plate 60 connected to the support rib 50. This allows the filter assembly 200 provided in this application embodiment to be easily removed and reassembled via the handheld plate 60.

[0111] The above are merely specific embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
