First embodiment

Referring to fig. 1, 3 and 4, the present embodiment provides a dishwasher, which includes a water tank 100, a filter assembly 200, a water pumping assembly 300 and a main wash basin 400;

the water tank 100 is provided with a sewage inlet 101 and a purified water outlet 102; the sewage inlet 101 is used for introducing sewage from the main washing tank 400; the purified water outlet 102 is used for introducing purified water filtered by the filter assembly 200 into the main washing tank 400;

one end of the water pumping assembly 300 is communicated with the sewage inlet 101 or the purified water outlet 102, and the other end of the water pumping assembly 300 is communicated with the main washing tank 400;

the filter assembly 200 is disposed between the sewage inlet 101 and the clean water outlet 102, and filters water introduced into the water tank 100.

The water tank 100 of the dishwasher provided in this embodiment is externally disposed on the main tub 400 of the dishwasher and is communicated with the main tub 400 through the pumping unit 300. The water tank 100 is provided with a sewage inlet 101 and a purified water outlet 102, sewage in the main wash basin 400 can enter the water tank 100 through the sewage inlet 101, and the sewage is filtered by the filter assembly 200 inside the water tank 100, flows out of the purified water outlet 102 of the water tank 100, and flows back to the main wash basin 400, so that the tableware can be washed conveniently. Since the sewage is filtered in the water tank 100, food residues are left in the water tank 100, thereby preventing the food residues from remaining in the main washing tub 400 of the dishwasher to be mixed with the main washing water, which is advantageous for dish cleaning. Meanwhile, the main washing water is not easy to become dirty due to filtration in the washing process, so that water does not need to be changed frequently, and water resources can be saved.

In an alternative embodiment, the water pumping assembly 300 includes a first water pump 301, a first water inlet pipe 302 and a first water outlet pipe 303;

one end of the first water inlet pipeline 302 is connected with the input end of the first water suction pump 301, and the other end of the first water inlet pipeline extends into the main washing tank 400;

The water tank 100 of the present embodiment is communicated with the main tub 400 of the dishwasher through the pumping unit 300. Specifically, the water tank 100 is disposed above the outer sidewall of the main tub 400, and the pumping assembly 300 is disposed between the sewage inlet 101 and the main tub of the dishwasher. The first water pump 301 is fixed through a water pump mounting plate arranged on the outer side wall of the main wash basin 400, and the fixing mode can be welding, threaded connection and the like; the first water inlet pipe 302 extends into the main washing tank 400 of the dishwasher, and under the action of the first water pump 301, sewage in the main washing tank 400 is pumped into the water tank 100 above the main washing tank 400 through the first water outlet pipe 303.

In the above technical solution, further, the diameter of the port of the first water inlet pipeline 302, which extends into one end of the main wash basin, is larger than the diameter of the pipe body of the first water inlet pipe.

Referring to fig. 2, one end of the first water inlet pipe 302 extending into the main wash tank of the dishwasher is trumpet-shaped, and the trumpet-shaped water inlet can enlarge the bottom water inlet breadth, so that the food waste around the trumpet-shaped opening is more uniformly sucked into the first water inlet pipe 302, and the formation of local vortex is avoided; in addition, the bell mouth is more favorable for the introduction of food residues, and the food residues are prevented from being directly blocked at the water inlet.

In the above technical solution, further, the filter assembly 200 includes a filter screen 201 and a filter screen support 202;

the filter screen support 202 is disposed on an inner wall of the water tank 100, and supports the filter screen 201.

The filter screen support 202 of the present embodiment is in a ring shape, the outer ring is matched with the inner wall of the water tank 100, i.e. is enclosed on the inner wall of the water tank 100, and the contour size of the inner ring is smaller than the contour size of the filter screen 201, so as to support the filter screen 201. It should be emphasized that the ring shape of the screen support is only a preferred embodiment of the present embodiment, and the screen support may also be other support structures, such as a plurality of supporting seats or fasteners uniformly arranged along the circumference of the inner wall of the water tank 100.

In the above technical solution, further, the filter screen 201 includes a side filter screen and a bottom filter screen;

the side filter screens are arranged around the inner wall of the water tank 100;

the bottom filter screen is arranged on the lower edge of the side filter screen.

For the clearance of making things convenient for food waste, the filter screen of this embodiment includes lateral part filter screen and bottom filter screen, and the bottom filter screen can cross most food waste of separation, and the lateral part filter screen can avoid food waste to pile up in the gap of filter screen 201 in water tank 100 inner wall.

In the above technical solution, further, the filter assembly 200 further includes two handles 203;

the two handles 203 are symmetrically arranged on two opposite edges of the upper edge of the side wall filter screen.

The handle 203 facilitates taking out and putting in the filter screen 201, and further facilitates cleaning of food residues.

In the above technical solution, further, a liquid level meter 103 is arranged on the water tank 100;

the liquid level meter 103 is used to detect the water level inside the water tank 100.

This embodiment sets up level gauge 103 in the inside of water tank 100 for the detection of water level in water tank 100, when food residue volume is big, the return water speed slows down, and the water level in the water tank 100 can rise, reaches the take the altitude when the water level, and level switch triggers, and the water pump stop work needs the manual work to clear up the filter screen this moment.

In the above technical solution, further, an overflow hole 104 is provided at a position of the water tank 100 near the top edge;

the overflow aperture 104 can communicate with the main wash tank 400.

This embodiment sets up overflow hole 104 in the top of level gauge 103, if level gauge 103 breaks down or filter screen 201 blocks up seriously, the water level rises too fast, and in order to prevent that the water level is too high and with rivers to equipment outside, set up 2 overflow holes 104 in the top of level gauge 103, this overflow hole 104 and main wash basin 400 intercommunication, when the condition that has the unusual water level to rise takes place, the water in the water tank 100 can overflow back to in the main wash basin 400 of dish washer.
