Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a cleaning machine for cleaning tableware and fruits and vegetables. Background Art

[0002] A dishwasher is a device that sprays cold or hot water onto dishes to remove dirt adhering to the dishes and clean the dishes. The dishes are placed in a dish rack inside a dishwasher cabinet. Generally, a dishwasher includes a pump and a nozzle for spraying washing water, a heater for generating hot water, etc.

[0003] As disclosed in a Chinese patent with the application number 201320889945.4 by the applicant, a sink-type cleaning machine includes a box body forming a washing space. The box body includes a sink body and a cover plate rotatably connected to the sink body. The bottom of the sink body has at least a concave water drainage area in the central part. A water pump for pumping water in the water drainage area to the washing space above the water drainage area is provided in the water drainage area. The water drainage area is covered with a water drainage plate with water drainage holes. A rotating spray arm for the water pump to discharge water is provided above the water drainage plate. A slag basket accommodated in the water drainage area is arranged on the water drainage plate, and a drainage port corresponding to the bottom of the slag basket is opened at the bottom of the water drainage area.

[0004] For the cleaning machine with the above structure, after the slag basket is used for a long time, a lot of residues and dirt may adhere to the slag basket. The residues and dirt are difficult to be manually cleaned. Over time, it is easy to block the slag net and the bottom of the slag basket, which not only affects the water return efficiency and is easy to be blocked, but also easy to breed bacteria and cause secondary pollution.

The drainage pump and the drainage valve are used to connect the slag collection box and the flushing assembly, and a water flow loop is formed among the slag collection basket, the drainage pump, the slag collection basket and the flushing assembly. In the state of slag collection after cleaning, the water outlet of the slag collection box can be closed through the drainage valve, and the drainage pump operates to suck the water flow and part of the residues into the slag collection box. The water separated from the residues then flushes the inner side wall of the slag collection basket through the water guide pipe and the flushing assembly, and the flushed residues enter the slag collection box through the drainage pump again. Thus, the flushing of the slag collection basket and the separation and collection of the residues are realized, so as to keep the slag basket clean, and further maintain a high water return efficiency, avoid the blockage of the slag basket and the growth of bacteria.

[0009] Preferably, the slag collection box is communicated with the drainage pump through a laterally extending diversion pipeline. The drainage valve has a water inlet communicated with the side of the slag collection box, and the water inlet is arranged opposite to the water incoming direction of the drainage pump. The drainage valve is used for controlling the opening and closing of the water inlet. The water outlet is arranged downstream of the water inlet. With the above arrangement, the slag collection box acts as a buffer chamber in the slag collection state, which is beneficial to realizing no residual water in the drainage assembly.

[0010] Preferably, a check valve sheet allowing residues to enter the slag collection box and preventing the residues from flowing back from the slag collection box to the drainage pump is arranged in the diversion pipeline near the slag collection box. With this structure, the backflow of the residues in the slag collection box can be avoided, which affects the cleaning.

A filter screen for filtering the water flowing upward through the water guide pipe is arranged between the open mouth and the cover plate. With such a structure, the residues can be separated by quantity and locked in the slag collection box, so as to avoid the residues flowing back to the flushing assembly, resulting in the blockage of the flushing assembly or affecting the cleaning effect of the slag collection basket.

[0012] Preferably, a clamping edge extending upward is provided at the top edge of the slag collecting basket. The flushing assembly is formed into an annular body that can be placed on the clamping edge. A water collecting cavity is formed inside the annular body, and spray holes for spraying the water in the water collecting cavity into the slag collecting basket are formed in the bottom wall of the annular body. With the above structure, it is convenient to install the flushing assembly and restrict the flushing range of the flushing assembly.

[0013] Preferably, the height of the water collecting cavity gradually increases from the outer edge of the annular body to the center. The bottom wall of the water collecting cavity forms a guiding surface that gradually slopes downward from the outside to the inside along the radial direction. The spray holes are multiple and are formed in the guiding surface. With the above structure, it is beneficial to avoid the mutual impact of water flows in the water collecting cavity, improve the water flow stability, and further improve the flushing effect.

[0014] Preferably, at least a part of the guiding surface extends radially inward into the clamping edge. The filter plate forms a guiding water surface that gradually slopes downward from the outside to the inside along the radial direction at the periphery of the slag collecting opening. A water absorption channel with a gradually decreasing height along the radial direction is restricted between the guiding surface and the guiding water surface. With such a structure, it is beneficial to utilize the Venturi effect to increase the water flow velocity at the slag collecting opening and further improve the slag collecting effect.

[0015] Preferably, the spray holes include a first spray hole and a second spray hole, and the first spray hole is located at the periphery of the second spray hole. Further, the first spray hole is arranged to gradually incline toward the center of the slag collecting basket from top to bottom, and the second spray hole is arranged to gradually incline toward the inner side wall of the slag collecting basket from top to bottom. There are multiple first spray holes and multiple second spray holes, and the first spray holes and the second spray holes are arranged at intervals in the circumferential direction of the annular body. With the above structure, the flushing area of the inner arm of the slag collecting basket is enlarged to eliminate the cleaning dead angle and improve the flushing effect on the inner arm of the slag collecting basket.

[0016] Compared with the prior art, the advantages of the present utility model are as follows: A slag collecting box and a flushing assembly are arranged at the bottom of the box body of the present utility model.

The drainage valve 6 is used to control the opening and closing of the water inlet 61. The water outlet 50 is opened downstream of the water inlet 61 and is located at the bottom wall of the pipeline. With the above arrangement, the slag collection box 5 acts as a buffer chamber in the slag collection state, which is beneficial to realizing no residual water in the drainage assembly.

[0026] A check valve 521 that allows residues to enter the slag collection box 5 and prevents the residues from flowing back from the slag collection box 5 to the drainage pump 4 is arranged in the diversion pipeline 52 near the slag collection box 5. With this structure, the residues in the slag collection box 5 can be prevented from flowing back, which affects the cleaning.

[0027] An opening is provided at the top of the slag collecting box 5. A cover plate 511 is detachably provided at the lower end of the water guide pipe 51 to cover the opening. A filter screen 512 capable of filtering the water flowing upward through the water guide pipe 51 is provided between the opening and the cover plate 511. With such a structure, the residue is weighed and locked in the slag collecting box 5 to prevent the residue from flowing back into the flushing assembly, causing blockage of the flushing assembly or affecting the cleaning effect of the slag collecting basket.

[0028] A clamping edge 22 extending upward is provided at the top edge of the slag collecting basket 2. The flushing assembly 7 is formed into an annular body that can be placed on the clamping edge.
