Description

TECHNICAL FIELD

[0001] The present application relates to a cleaning machine for cleaning dishes, fruits and vegetables. BACKGROUND

[0002] With the increasing improvement of people's living standards, dishwashers as a kind of kitchen household appliances are increasingly entering families. The dishwashers on the market are generally divided into three types: table type, cabinet type and slot type. Among them, the table type dishwasher is a whole independent structure, which is generally placed on the table for use; the cabinet type dishwasher is also an independent structure, but needs to be embedded in the kitchen cabinet for use; the slot type dishwasher is combined with the sink, which is generally installed in the kitchen cabinet for use.

[0003] Compared with the table type and cabinet type dishwashers, the slot type dishwasher has a smaller volume and can clean a smaller number of dishes at a time, but consumes less energy for each cleaning. The applicant's prior application ZL201310752030.3 "Open sink cleaning machine" discloses a slot type dishwasher, which adopts an open type water pump, and the spray arm serves as a part of the water pump volute, and simultaneously has the functions of water pumping and water column spraying. The Chinese patent application for invention with the application publication number CN106859563A "Energy-saving dishwasher" (application number: CN201611232345.5) discloses a table type or cabinet type dishwasher, which includes a cavity for accommodating tableware and providing a cleaning space, a spraying system for spraying water to clean the tableware, and a pump body for pumping water and supplying water to the spraying system; the spraying system is arranged in the cavity; the water pumping end of the pump body is communicated with the cavity, and the water supplying end is communicated with the spraying system; the spraying system includes an inner water pipe and two or more sets of spraying devices, and the two or more sets of spraying devices are arranged on the inner water pipe; the water supplying end of the pump body is connected with a water distribution device, the water distribution device is provided with two or more water outlets corresponding to the two or more sets of spraying devices, and the spraying devices are communicated with the corresponding water outlets; during operation, the water distribution device opens one or more water outlets according to the instruction, so that one or more sets of spraying devices perform cleaning work.

[0004] In the above-mentioned dishwasher capable of bottom spraying and top spraying, the bottom water supply and the top water supply generally need to be separated by a water distribution device, and the pipeline of the top water supply is communicated with the water distribution device through the filter screen plate. For the dishwasher using a closed type water pump, since the water pump does not need to be installed in cooperation with the filter screen plate, the filter screen plate does not need to be disassembled, but for the dishwasher using an open type water pump, it is difficult to disassemble the filter screen plate on the basis of cooperation between the filter screen plate and the water supply pipeline, so that the area below the filter screen plate is difficult to clean. SUMMARY

[0005] The technical problem to be solved by the present invention is to provide a cleaning machine which can connect the filter screen plates with the water supply pipe and clean the underside of the filter screen plates by reasonably splicing the filter screen plates in response to the current status of the existing technology.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a cleaning machine, comprising a box body, a first water outlet structure, a second water outlet structure and a water pumping mechanism, the bottom of the box body is provided with a concave draining area, the top of the draining area is covered with a draining plate, the first water outlet structure is provided at the bottom of the box body and is located above the draining plate, the second water outlet structure is provided above the first water outlet structure and is fluidically connected to the water pumping mechanism through a water supply pipe, and is characterized in that: the draining plate includes a first part and a second part that can be spliced ​​with each other, the bottom wall of the draining area extends upward to form an assembly table arranged close to the lower wall surface of the first part, and a water diversion chamber is provided below the assembly table that is fluidically connected to the water pumping mechanism, the lower end of the water supply pipe passes through the first part and is connected to the water diversion chamber and presses the first part onto the assembly table, and the second part is detachably connected to the bottom of the box body.

[0007] In the above solution, a U-shaped groove is provided at the inner edge of the first part, and correspondingly, a clamping edge is extended downward from the corresponding edge of the second part to form a clamping edge that can be clamped in the U-shaped groove. The above structure facilitates the splicing of the first and second parts and maintains the sealing of the splicing. On the other hand, the connection between the water supply pipe and the water diversion chamber is already formed when the water supply pipe leaves the factory, that is, the first part is constrained to the bottom of the box body and cannot be disassembled. However, in order to facilitate cleaning of the part in the drainage area, the second part needs to be removable. The clamping edge of the second part is pressed and held in the U-shaped groove. When the second part is disassembled, the constraint relationship between the second part and the box body is cancelled, and the second part can be directly moved upward and removed, which is convenient for disassembly and assembly.

[0008] Preferably, the U-shaped groove is formed by sinking the inner edge of the first part. When assembled, the upper wall of the first part and the upper wall of the second part remain roughly flush at the junction. This structure helps maintain a good water flow guidance effect and avoids obstruction of water flow and affecting the return water effect.

[0009] Preferably, the assembly platform has a water outlet connected to the water diversion chamber, the first portion has an assembly opening corresponding to the water outlet, and the lower end of the water supply pipe has a plug portion that passes through the assembly opening and is sealed with the water outlet. The connection between the water supply pipe and the plug portion is formed with a boss that can press against the first portion. This structure helps to improve the compactness and sealing of the connection between the water supply pipe, the first portion, the assembly platform, and the water diversion chamber.

[0010] Preferably, the inner wall of the assembly opening is provided with a through-going slot, and the outer peripheral wall of the insertion part is provided with a protruding clamping member which can be clamped with the lower wall of the first part through the slot. This structure can prevent the water supply pipe from being loosened from the first part, and can prevent the lower end of the water supply pipe from being separated.

[0011] Preferably, the upper wall of the assembly base is provided with an assembly sleeve extending upward around the water passage, and the outer peripheral wall of the insertion part is arranged close to the inner peripheral wall of the assembly sleeve in the assembled state, and a sealing ring is arranged between the outer peripheral wall of the insertion part and the inner peripheral wall of the assembly sleeve. This structure can further improve the sealing performance of the connection.

[0012] Preferably, the outer edge of the first part is downwardly extended to form a first surrounding edge arranged close to the inner peripheral wall of the draining area, and the outer edge of the second part is downwardly extended to form a second surrounding edge arranged close to the inner peripheral wall of the draining area. This structure can improve the compactness of the connection between the draining plate and the box body, and can prevent residues from being accumulated in the connection gap.
