Description

Technical Field

[0001] This utility model relates to the field of tableware washing technology, specifically a water-saving tunnel dishwasher. Background Technology

[0002] After use, tableware needs to be washed. The traditional washing method is manual washing, which is inefficient and time-consuming. In order to improve cleaning efficiency and ease of operation, dishwashers are usually used to wash tableware. A tunnel dishwasher is a common type of dishwasher.

[0003] When using a conventional tunnel dishwasher, the dishes are usually placed in a dish rack, and then the dish rack and dishes are pushed in from one end of the machine. They are then transported inside the machine by a conveyor and finally come out from the other end. Throughout the process, a spray device sprays high-pressure water jets to clean the dishes, thereby removing grease and residue.

[0004] Existing tunnel dishwashers have the following problems: they spray and clean dishes through nozzles distributed throughout the equipment, and the water used for spraying is either disposed of as waste or purified and reused. The former wastes resources, while the latter requires centralized treatment after washing, which is cumbersome. Therefore, we propose a water-saving tunnel dishwasher. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a water-saving tunnel dishwasher. By setting up a circulation mechanism, the cleaning process is divided into multiple stages. The cleaning water is reused through circulation between stages and self-circulation within stages. It is easy to operate, saves resources, and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-saving tunnel dishwasher, including a housing, with evenly distributed rinsing nozzles on the upper side of the interior of the housing, and also including a circulation mechanism;

[0007] The circulation mechanism includes a rinsing zone, a cleaning zone, a rinsing zone, a circulation pipe 1, a circulation pipe 2, a water inlet pipe, a drive assembly, and a filter assembly. The interior of the housing is divided into three areas from left to right by a partition: a rinsing zone, a cleaning zone, and a rinsing zone. A circulation pipe 1 is located at a drain outlet on the bottom wall of the rinsing zone, and its outlet extends through the top wall of the rinsing zone. A circulation pipe 2 is located at a drain outlet on the bottom wall of the cleaning zone, and its outlet extends through the top wall of the cleaning zone. A water inlet pipe is located on the top wall of the rinsing zone. A drive assembly is located on the upper surface of the housing, and a filter assembly is located inside the housing. Through the circulation mechanism, the cleaning process is divided into multiple stages. Clean water is reused through circulation between stages and self-circulation within stages, making operation convenient and resource-saving.

[0008] Furthermore, the drive assembly includes a water pump, a confluence valve, and a water inlet pipe. Water pumps are connected in series in the middle of circulation pipe one, circulation pipe two, and the water inlet pipe. Confluence valves are also connected in series in the middle of circulation pipe one and circulation pipe two. The confluence valves are all located behind the adjacent water pumps. A water inlet pipe is provided at the other water inlet of each confluence valve. The input ends of the water pumps and confluence valves are electrically connected to the output end of an external controller to facilitate the normal operation of the cleaning work.

[0009] Furthermore, the filter assembly includes slots, fixing frames, and filter screens. Slots are provided on the inner walls of both the cleaning and rinsing areas. Fixing frames are inserted into the inside of each slot, and filter screens are provided on the lower inside of each fixing frame to facilitate filtration.

[0010] Furthermore, the outlet ends of the first circulation pipe, the second circulation pipe, and the inlet pipe are respectively equipped with spray pipes, and the lower side of the outer surface of the spray pipes is equipped with evenly distributed rinsing nozzles to facilitate spray cleaning.
