Description

Technical Field

[0001] This utility model relates to a cleaning machine for cleaning tableware and / or fruits and vegetables. Background Technology

[0002] A dishwasher, or cleaning machine, is a device that sprays cold or hot water onto dishes to remove dirt and grime and clean them. Dishes are placed in a dish rack inside the dishwasher cabinet. A typical dishwasher includes a pump and nozzles for spraying washing water, a heater for generating hot water, and a wastewater basket and drain pump. The wastewater basket filters food residue, and the drain pump discharges the filtered wastewater.

[0003] For example, the Chinese utility model patent disclosed in patent application number CN202222172825.4 (publication number CN218279557U) entitled "A Cleaning Machine" includes a box and a slag basket. The bottom of the box is provided with a drain outlet. The slag basket is located at the bottom of the box and its lower port is arranged corresponding to the drain outlet. The outer bottom of the box is provided with a drain pump and a drain valve for providing power for drainage. It also includes a water return structure that can draw the drainage back to the drain outlet and flush the slag basket upwards by the drain pump when the drain valve is closed.

[0004] After a dishwasher has been used for a period of time, the waste basket needs to be disassembled and cleaned regularly. However, existing waste baskets are usually disassembled and removed from the sink by rotating them. For example, Chinese utility model patent application number CN202022034350.3 (publication number CN213405934U) discloses a cleaning system and a cleaning machine including the same. The inner circumferential surface of the central tube is provided with a mounting protrusion extending circumferentially around the central tube, and the mounting protrusion is located below the side opening. The waste basket includes a bracket and a mounting groove circumferentially arranged around the bracket. One end of the mounting groove forms an opening, and the mounting protrusion can be inserted into the mounting groove through the opening. When installing the waste basket, the waste basket is placed into the connecting port, the bracket of the waste basket extends into the central tube, the opening of the mounting groove is aligned with the mounting protrusion, and the waste basket is rotated to insert the mounting protrusion into the mounting groove, thereby fixing the waste basket to the central tube. When removing the waste basket, the waste basket is rotated in the opposite direction to remove it from the connecting port.

[0005] This rotating disassembly method is not convenient enough, and it is difficult for users to disassemble and assemble. In addition, the existing waste basket is generally rigidly connected to the cabinet, which poses a risk of waste leakage and reduces the cleaning effect of the dishwasher. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a cleaning machine with a slag basket that is easy to disassemble and install and does not leak slag, in light of the current state of the technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a cleaning machine, comprising...

[0008] A slag basket, used to filter out residue;

[0009] The box body has a recessed water return area at the bottom, the top of which is covered by a filter plate, and the bottom of which is provided with a drain outlet. The slag basket passes through the filter plate and is connected to the drain outlet at the bottom.

[0010] The feature is that the slag basket can move up and down relative to the filter plate, the bottom of the box extends downward around the drain outlet to form a tube, the lower part of the slag basket can be detachably inserted into the tube, and a first sealing ring is provided between the lower part of the slag basket and the tube. When the lower part of the slag basket is inserted into the tube, the first sealing ring is interference-fitted with the lower part of the slag basket.

[0011] To prevent slag leakage between the slag basket and the filter plate, the filter plate has perforations for the slag basket to pass through. A flange is provided on the outer peripheral wall of the slag basket, with the slag inlet located above the flange. When the lower part of the slag basket is inserted into the tube, the flange presses against the top wall surface of the filter plate located around the perforations. The flange acts as a shield, preventing residue from leaking through the gap between the slag basket and the filter plate without entering the inlet; simultaneously, the flange also helps to vertically position the slag basket.

[0012] Preferably, the lower outer wall of the slag basket is tapered, wider at the top and narrower at the bottom. This ensures that when the user installs the slag basket, the bottommost part is the smallest and does not come into contact with the soft rubber structure, facilitating downward insertion. As the user continues to press down, the contact area between the slag basket and the first sealing ring gradually increases, improving not only the sealing performance of the slag basket but also providing a better installation feel.

[0013] Preferably, the top wall of the first sealing ring is conical, wider at the top and narrower at the bottom, which guides the installation of the slag basket into the pipe body.

[0014] In order to circulate the water and eventually discharge the waste liquid, the cleaning machine also includes a drainage mechanism. The drainage mechanism has a pump casing located at the bottom of the housing. The water inlet of the pump casing is fitted onto the pipe body, and a second sealing ring is provided between the pump casing and the pipe body to prevent water leakage between the pump casing and the pipe body.

[0015] Preferably, the first and second sealing rings are connected by a connecting portion, and the first and second sealing rings, along with the connecting portion, together constitute a sealing element. The longitudinal section of this sealing element is a U-shape with an open top. This structure is simple, and the sealing element can be injection molded or wrapped around the bottom of the tube body, thus simultaneously installing the first and second sealing rings.

[0016] To fix the pump casing relative to the housing, the pump casing and the housing are connected by a connector.

[0017] Compared with the prior art, the advantages of this utility model are as follows: This utility model enables the slag basket to move up and down relative to the filter plate, and forms a tube at the drain outlet of the box. The lower part of the slag basket can be inserted into the tube, realizing the connection between the slag basket and the drain outlet. Furthermore, a first sealing ring is provided between the slag basket and the tube. The first sealing ring not only prevents slag leakage between the slag basket and the tube, but also ensures a stable connection between the two and plays a positioning role. At the same time, under the action of external force, the slag basket can be separated from the tube.

[0018] This invention allows for easy assembly and disassembly of the slag basket from the housing simply by inserting and removing it. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an adhesive connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model patent based on the specific circumstances.

[0027] like Figures 1-5 As shown, the washing machine of this preferred embodiment includes a slag basket 1, a housing 2, and a drainage mechanism 3. The slag basket 1 is used to filter the residue in the water after washing the tableware. In this embodiment, the function of the slag basket 1 is the same as that of the prior art, and the structure of the slag basket 1 can also adopt the prior art.

[0028] The bottom of the housing 2 is provided with a recessed return water area 21, the top of which is covered by a filter plate 22, and the bottom of the return water area 21 is provided with a drain outlet 23. The sludge basket 1 passes through the filter plate 22 and its lower part is connected to the drain outlet 23. The lower part of the sludge basket 1 forms a liquid discharge port, which is the prior art.

[0029] The bottom of the box 2 extends downward around the drain outlet 23 to form a tube 24. The lower part of the slag basket 1 is detachably inserted into the tube 24. A first sealing ring 41 is provided between the lower part of the slag basket 1 and the tube 24. When the lower part of the slag basket 1 is inserted into the tube 24, the first sealing ring 41 is interference-fitted with the lower part of the slag basket 1.

[0030] The slag basket 1 can move up and down relative to the filter plate 22. The filter plate 22 has a perforation 221 for the slag basket 1 to pass through. A flange 11 is provided on the outer peripheral wall of the slag basket 1. The slag inlet of the slag basket 1 is located above the flange 11. When the lower part of the slag basket 1 is inserted into the tube 24, the flange 11 presses against the top wall surface of the filter plate 22 located around the perforation 221. The flange 11 serves to block and prevent residue from leaking through the gap between the slag basket 1 and the filter plate 22 without entering the slag inlet; at the same time, the flange 11 also serves to position the slag basket 1 vertically.

[0031] In addition, the lower outer wall of the slag basket 1 is conical, wider at the top and narrower at the bottom. In this embodiment, the lower part of the slag basket 1 is a conical structure 10, wider at the top and narrower at the bottom. This way, when the user installs the slag basket 1, the bottom part of the slag basket 1 is the smallest and does not come into contact with the first sealing ring 41, making it easy to insert downwards. As the user continues to press down to insert, the contact area between the slag basket 1 and the first sealing ring 41 gradually increases, which not only improves the installation sealing performance of the slag basket 1, but also creates a better installation feel.

[0032] Meanwhile, the top wall of the first sealing ring 41 is cone-shaped with a larger top and a smaller bottom, which guides the installation of the slag basket 1 into the tube body 24.

[0033] In this embodiment, the slag basket 1 can be easily installed and removed from the housing 2 simply by vertically inserting and removing it. In other words, the slag basket 1 is installed with an insert-type structure; when cleaning the slag basket 1, the user can simply pull it out for cleaning and insert it back in after cleaning. The lower part of the slag basket 1 forms an interference fit with the first sealing ring 41, which not only solves the slag leakage problem through sealing with the first sealing ring 41, but also the friction between the lower part of the slag basket 1 and the first sealing ring 41 securely mounts the slag basket 1 onto the housing 2.

[0034] The structure of the drainage mechanism 3 can adopt existing technology, and the function of the drainage mechanism 3 is the same as that of existing technology. The drainage mechanism 3 has a pump casing 31 located at the bottom of the box 2. The pump casing 31 is connected to the box 2 by a connector 32 (such as a bolt). The water inlet 30 of the pump casing 31 is fitted onto the pipe body 24, and a second sealing ring 42 is provided between the pump casing 31 and the pipe body 24 to prevent water leakage between the pump casing 31 and the pipe body 24.

[0035] In this embodiment, the first sealing ring 41 and the second sealing ring 42 are connected by the connecting part 43. The first sealing ring 41, the second sealing ring 42, and the connecting part 43 together constitute the sealing element 4, which has a U-shaped longitudinal section with an open top. This structure is simple. The sealing element 4 is injection molded or wrapped around the bottom of the tube body 24, that is, soft rubber is wrapped around both the inner and outer sides of the tube body 24, thus simultaneously installing the first sealing ring 41 and the second sealing ring 42. The sealing element 4 can be made of flexible materials such as rubber or silicone.
