Abstract

The present invention relates to a water tank cleaning machine, comprising a tank body, an air guide duct, and an air guide box body. The tank body comprises a surrounding edge, a vertical tube, and a tank bottom connected in sequence from top to bottom. The bottom edge of the surrounding edge is connected to the top edge of the vertical tube by flanging, and the bottom edge of the three-dimensional body is connected to the top edge of the tank bottom by flanging. The relatively independent surrounding edge, vertical tube, and tank bottom are connected by splicing, which reduces the process difficulty of welding or drawing each part, and the thickness of each part can be adjusted as needed, which saves materials and reduces costs to the maximum extent; the vertical tube part can form a second installation groove with a larger depth. After the air guide box body is embedded in the second installation groove, the second air outlet can be moved down to make it closer to the tank bottom, so that the water accumulated in the tank bottom can be dried more effectively. The splicing structure between the surrounding edge and the top of the vertical tube is used to embed the air guide duct, which is mainly used to dry the upper part of the tank body and the door body. The combination of upper and lower air supply effectively improves the drying effect.

Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, in particular to a sink cleaning machine. Background Art

[0002] At present, the sinks of sink-type cleaning machines on the market are generally made of stainless steel, and the processing methods are mainly welding and deep drawing.

[0003] Among them, for the welding process, due to the large welding deformation of stainless steel materials, it is difficult to control the dimensional accuracy of the sink, which limits the overall shape of the sink body, resulting in a single structure of the sink body, which in turn restricts the development of more functional structures of the sink-type cleaning machine. In addition, the welding process has extremely high requirements for the welding mold. To achieve good sealing at the welding point will lead to low welding efficiency and high cost, and if the sealing effect at the welding point is poor, it cannot meet the requirements. For the deep drawing process, the sink drawn by the deep drawing process generally has a depth smaller than the opening width of the sink, making it difficult to increase the depth of the sink. At the same time, the upper, middle and lower parts of the trough body have different requirements for material thickness due to different load-bearing requirements. However, at present, whether the trough body is manufactured by welding or deep drawing, it is limited by the process and can only be made into a structure with consistent thickness everywhere, resulting in material waste and increased costs.

[0004] In addition, the current sink-type washing machines need to meet the requirement of high water level without overflow when washing fruits and vegetables. The drying air inlet is generally set at the upper part, which cannot effectively dry the bottom where the water accumulates, resulting in poor overall drying effect of the tank; the top wall of the door is also prone to water dripping, affecting the user experience. In addition, the air outlet is mainly installed at the middle height of the tank body, and is passively discharged by the pressure difference between the inside and the outside. The gas has poor fluidity and is not conducive to drying the tank. Summary of the invention

[0057] The junction between the second branch air duct 4122 and the extension part 4128 forms a smoothly transitioned inverted U-shaped flow guide structure 001 at the inner corner and an inclined flow guide slope 002 at the outer corner. This structure is conducive to reducing wind speed loss, maintaining a large gas flow rate, and improving the drying effect.

At the same time, the splicing structure between the surrounding edge 11 and the top of the vertical tube 12 is used to embed the air guide duct 2, which is mainly used to dry the upper part of the groove body 1 and the door body. The combination of upper and lower air supply effectively improves the drying effect.
