Description

Technical Field

[0001] The invention relates to a kitchen appliance, in particular to a washing machine for washing dishes, vegetables or fruits. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are increasingly entering households. Dishwashers on the market are generally divided into three types: tabletop, cabinet, and tank. Among them, tabletop dishwashers are integrated independent structures and are generally placed on the table for use; cabinet dishwashers are also independent structures, but need to be embedded in kitchen cabinets for use; tank dishwashers are combined with sinks and are generally installed in kitchen cabinets for use.

[0003] At present, the structure of the relatively mature water tank type cleaning machine on the market is mainly as described in the Chinese patent "Water Tank Type Cleaning Machine" (application number: CN201310750968.1) with the authorization announcement number CN104224074B, that is, it includes a box body forming a washing space, the box body includes a water tank body and a cover plate rotatably connected to the water tank body, the bottom of the water tank body has a concave drain area at least in the central part, and the drain area is provided with a water pump that pumps the water in the drain area out to the washing space above the drain area, the drain area is covered with a drain plate with drain holes, and a rotating spray arm connected to the water pump fluid and having a water outlet hole is arranged above the drain plate. By setting a drain area covered with a drain plate and setting the water pump in the drain area, the water pump is isolated from the washing area, so that the water flowing back into the water pump is first filtered by the drain plate.

[0004] The sink body of the above-mentioned existing sink-type cleaning machine is made of stainless steel material, and the processing methods are mainly welding and drawing. 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, low welding efficiency and high cost; for the drawing process, the deformation limit of the stainless steel material directly limits the drawing depth of the sink. The sink drawn by the drawing process generally has a depth less than the opening width of the sink. At present, it is difficult for the processes around the world to achieve a drawing depth greater than the opening width of the sink body, which causes the sink to occupy a larger installation space in the kitchen during installation and greatly limits the washing space of the sink.

[0005] The plastic sink body is highly plastic, and the depth of the sink body can be increased as needed, so that the kitchen space can be effectively utilized. However, since the water pump of the cleaning machine is located at the bottom of the sink body, the spray arm at the bottom of the sink body needs to be installed and used in conjunction with the water pump, resulting in that although the depth of the sink body is increased, the space in the top area of ​​the sink body cannot be effectively utilized. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a cleaning machine which can make the upper space of the water tank body be used independently and improve the space utilization rate of the water tank body in view of the current status of the prior art.
