Background

With the increasing living standard of people, the dish washing machine is used as a kitchen household appliance and is more and more introduced into families. The dish-washing machines on the market are generally divided into a table type dish-washing machine, a cabinet type dish-washing machine and a trough type dish-washing machine, wherein the table type dish-washing machine is an integral independent structure and is generally placed on a table top for use; the cabinet type dish washing machine is also an independent structure, but needs to be embedded into a kitchen cabinet for use; the sink dishwasher is combined with a sink and is generally installed in a kitchen cabinet for use.

At present, the structure of a relatively mature water tank type cleaning machine in the market is mainly described in chinese patent "water tank type cleaning machine" (application number: CN201310750968.1) with publication number CN104224074B, that is, the water tank type cleaning machine comprises a tank body forming a washing space, the tank body comprises a water tank body and a cover plate rotatably connected to the water tank body, a concave draining area is arranged at least at the central part of the bottom of the water tank body, a water pump for pumping water in the draining area to the washing space above the draining area is arranged in the draining area, the draining area is covered with a draining plate with draining holes, and a rotary spray arm which is communicated with the water pump and has water outlet holes is arranged above the draining plate. By arranging the draining area covered with the draining plate and arranging the water pump in the draining area, the water pump is isolated from the washing area, so that the water flowing back to the water pump is filtered by the draining plate.

The water tank body of the existing water tank type cleaning machine is made of stainless steel materials, and the processing mode mainly comprises two modes of welding and deep drawing. For the welding process, the welding deformation of the stainless steel material is large, so that the dimensional precision of the water tank is difficult to control, the integral shape of the water tank body is limited, the structure of the water tank body is single, the development of more functional structures of the water tank type cleaning machine is further restricted, and the welding process has extremely high requirements on a welding die, low welding efficiency and high cost; for the drawing process, the drawing depth of the water tank is directly limited by the deformation limit of the stainless steel material, the depth of the water tank is generally smaller than the opening width of the water tank after the water tank is drawn by the drawing process, and the drawing depth of the water tank is difficult to be larger than the opening width of the tank body in the current worldwide process, so that the water tank occupies a large installation space of a kitchen when being installed, and the washing space of the water tank is limited to a great extent.
