Description

Technical Field

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

[0002] Dishwashers have been widely used in home kitchens. Dishwashers are generally provided with a spray arm for spraying water, a concave water return area is provided at the bottom of the cabinet, the top of the water return area is covered with a filter plate, and a water pump is used to pump water from the water return area to the spray arm above the filter plate to realize the circulation spraying of washing water.

[0003] The applicant's prior patent ZL 202121479018.6 "A Cleaning Machine" discloses a structure including an inner tank and a water cup, which is installed at the bottom of the inner tank to form a water return area that is recessed relative to the washing chamber. Usually, in order to take into account the water return and drying effects at the bottom of the inner tank, the bottom of the inner tank is made of metal. The bottom wall of the inner tank of the above-mentioned patent forms a diversion slope that gradually slopes downward from the edge to the water return area to guide the water flow to the water return area. When the area of ​​the water return area is large, the diversion slope can basically meet the diversion requirements, but when the area of ​​the water return area is small, some food residues may be retained on the bottom wall of the inner tank, affecting the residue collection effect.

[0004] In order to solve the above problems, the present application proposes a solution CN202320985194.X "Inner tank and cleaning machine for cleaning machine", and a first guide slope and a second guide slope are arranged in sequence from the edge of the bottom wall inward inside the inner tank. The second guide slope is closer to the return water outlet, and the slope of the second guide slope is greater than that of the first guide slope. In the process of diverting the return water, secondary acceleration of the return water is achieved, which is beneficial to greatly increase the return water speed, avoid residue accumulation on the bottom wall of the inner tank, and improve the residue collection effect.

[0005] Although the above solution solves the problem of backflow and residue collection on the bottom wall of the inner tank, due to the small size of the water cup, after the installation of functional parts such as the water pump, heating element, and drain valve pump, water often accumulates at the bottom of the water cup, resulting in poor drying effect and easy breeding of bacteria.

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] like Figure 1 , 2 As shown, the cleaning machine of this embodiment includes an inner tank 1, and the bottom wall of the inner tank 1 is provided with a concave water return area 11, which is formed into a triangular structure with a smooth transition at the corner. The bottom wall of the water return area 11 is divided into three mutually connected fan-shaped areas with the central part of the triangular structure as the center and each smoothly transitioned corner as the outer edge. The first fan-shaped area 10 is arranged lower than the second fan-shaped area 20 and the third fan-shaped area 30. The second fan-shaped area 20 and the third fan-shaped area 30 gradually tilt downward from their arc edges to the center to form a diversion structure for converging water to the first fan-shaped area 10. The second fan-shaped area 20 and the third fan-shaped area 30 are symmetrically arranged relative to the connecting edge of the two. This structure is conducive to improving the effect of no residual water at the bottom of the water return area.

[0028] A drainage port 13 is provided in the central part of the first sector area 10, a slag collection basket is installed in the return water area 11 above the drainage port 13, and a drainage assembly is installed at the bottom of the inner tank 1 below the drainage port 13. Such a structure is used to improve the return water efficiency, and the bottom of the return water area is free of residual water after drainage.

[0029] The first sector-shaped area 10 gradually slopes downward from its edge to the drain outlet 13 to form a water-guiding structure. This structure is beneficial to further improve the effect of eliminating residual water in the first sector-shaped area.

[0030] The first sector area 10 is formed with a first mounting platform 14 arranged around the periphery of the drain port 13 and used to mount the drain assembly, and the first mounting platform 14 is arranged horizontally. The first mounting platform 14 is set as a platform mainly to improve the reliability of the drain assembly after installation. The height difference between the edge of the first sector area 10 and the first mounting platform 14 is 5 to 10 mm. This structure is conducive to achieving a better drainage effect.

[0031] The first fan-shaped area 10 gradually slopes downward from its arc edge to the edge of the first mounting platform 14 to form a first water guide slope 101, and the first fan-shaped area 10 gradually slopes downward from its straight edge to the first mounting platform 14 to form a second water guide slope 102. The first water guide slope 101 and the second water guide slope 102 together form a water guide structure, which is conducive to achieving the drainage effect of the first fan-shaped area 10 and achieving no residual water.

[0032] The second fan-shaped area 20 gradually tilts downward from its arc edge to the center to form a first diversion slope 201, and the third fan-shaped area 30 gradually tilts downward from its arc edge to the center to form a second diversion slope 301. The slopes of the first diversion slope 201 and the second diversion slope 301 are 3 to 6 degrees, preferably 4 degrees. The first diversion slope 201 and the second diversion slope 301 together constitute the diversion structure of this embodiment. The above structure can utilize the structure of the fan-shaped area to converge water from the large edge to the center point, and flow into the lower first fan-shaped area 10, so as to achieve no residual water in the second fan-shaped area 20 and the third fan-shaped area 30.

[0033] The first guide slope 201 and the second guide slope 301 are concave at the connection to form a guide groove 15 for guiding water to the first fan-shaped area 10. This structure is conducive to further improving the effect of no residual water in the second fan-shaped area 20 and the third fan-shaped area 30. The guide groove 15 gradually slopes downward from the side wall of the return water area 11 to the first arc-shaped area 10, and the inclination is 2 to 5 degrees. This structure is conducive to achieving a better drainage effect.

The second mounting platform 16 is set as a platform, mainly to improve the reliability of the water pump drive after installation. The second guide slope 301 is provided with a mounting opening 17 for mounting the heating element, and the edge of the mounting opening 17 extends upward to form an assembly edge 171. The above structure is conducive to improving the installation reliability of the heating element.

[0035] A smoothly transitional arc surface 18 is formed between the bottom wall and the side wall of the water return area 11. The larger the R angle of the arc surface 18, the better, generally above R10, so as to achieve no residual water at the root of the water return area.

[0036] The side wall of the water return area 11 gradually tilts outward from bottom to top relative to the water return area 11 to form a guide surface 19. The slope of the guide surface 19 is 8 to 18 degrees, preferably 10 degrees. The above structure is conducive to improving the water return effect, and cooperates with the above arc surface to improve the effect of no residual water at the root of the water return area.

[0037] In this embodiment, the bottom wall of the triangular water return area 11 is set to be relatively uniform to obtain three fan-shaped areas. The three fan-shaped areas are naturally connected by utilizing the characteristics of the triangular structure. The second fan-shaped area 20 and the third fan-shaped area 30 gradually tilt downward from their arc edges to the center to form a diversion structure for converging water to the first fan-shaped area 10, which is beneficial for guiding the accumulated water in the second and third fan-shaped areas to the first fan-shaped area for installing the base station, which is not only beneficial for improving the water return efficiency, but also facilitates the realization of no residual water at the bottom of the water cup, which is convenient for drying.
