Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a circulating spray dishwasher. Background Technology

[0002] As people's living standards continue to improve, the demand for automated and efficient dishwashing is growing. Dishwashers, as an important part of kitchen appliances, are gradually entering ordinary households and the catering industry. In existing technologies, traditional dishwashers generally adopt a one-time spray washing mode, which has low water resource utilization during the washing process. The washing liquid and clean water are usually discharged after one spray, resulting in significant waste.

[0003] Therefore, we propose a circulating spray dishwasher to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a circulating spray dishwasher.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] During use, this utility model circulating spray dishwasher is connected to an external power source. The dishes and chopsticks to be washed can be placed on the rack, and the rack can be slid into the cabinet through the guide rail before the cabinet door is closed.

[0016] Then, the external water supply pipeline is connected through the water inlet pipe. At this time, under the pumping action of the pump in the storage tank, the washing liquid in the storage tank enters the water inlet pipe, and then the mixture of cleaning water and washing liquid enters the inner ring shell.

[0017] At this time, the pressure pump works, drawing the mixture in the inner ring shell through the suction main pipe, and then discharging it through two water pressure rotary nozzles. The mixture is sprayed out by rotating on the two water pressure rotary nozzles to spray and rinse the bowls and chopsticks on the shelf.

[0018] After one use, the mixture carrying impurities falls through the mesh plate into the outer ring shell. At this time, the main suction pipe and the water inlet pipe are closed, and the suction branch pipe is opened. Under the action of the pressure pump, the suction branch pipe sucks the mixture in the outer ring shell and then sprays it for a second time through the water pressure rotating nozzle. The number of times the mixture is circulated is specified according to the cleaning needs. During this process, the impurities in the mixture can be filtered out through the filter screen design.

[0019] Finally, open the bottom valve to drain the mixture after multiple cycles, then open the water inlet pipe to fill the inner ring shell with clean rinsing water, and perform a final rinse on the dishes and utensils on the shelf.

[0020] Furthermore, an electric heating structure can be added inside the inner and outer ring shells to heat the rinsing water, and a drying component can be installed at the top of the inner wall of the cabinet to dry the dishes and utensils with hot air after cleaning.

[0021] This utility model adopts an inner and outer ring shell design, which allows the cleaning liquid to flow into the outer ring shell after one spray and be drawn back into the nozzle for a second spray, significantly improving the utilization efficiency of the washing liquid.

[0022] By configuring a filter screen during the circulation process, residues and impurities in the mixture can be effectively filtered out, preventing nozzle clogging and improving the cleanliness of the washing liquid.

[0023] By repeatedly using the mixture, the consumption of water and detergent during the cleaning process is greatly reduced, resulting in good energy-saving and environmental protection effects. Attached Figure Description
