Description

Technical Field

[0001] The present application relates to the technical field of kitchen sewage discharge, and in particular to a central kitchen sewage discharge device. Background Art

[0002] Since food processing operations such as cooking, steaming, boiling and frying are required in the kitchen, a large amount of oil smoke will be generated. After long-term use, the oil smoke will adhere to the surface of the kitchen, which will directly affect the overall cleaning effect. Therefore, it is necessary to use a smoke exhaust device to quickly exhaust the oil smoke out of the room in time. During the oil smoke exhaust process, the oil stains in the oil smoke will remain on the filter of the smoke exhaust device. After long-term use, personnel are required to clean the filter.

[0003] The utility model patent with announcement number CN219510868U proposes a central kitchen smoke exhaust device, including a mounting frame, the left and right sides of the mounting frame are fixedly connected with mounting plates, the front sides of the two mounting plates are threaded with mounting bolts, four connecting rods are installed on the inner top wall of the mounting frame, a strip frame is installed on the bottom end of the connecting rod, and a fan is installed on the inner wall of the strip frame.

[0004] The above-mentioned central kitchen smoke exhaust device, when the filter screen inside the smoke exhaust frame needs to be disassembled and cleaned, it is only necessary to turn on the two motors to make the screw drive the movable plate to move outward, and the movable plate drives the limiting card plate to disengage from the limiting groove on the surface of the smoke exhaust frame through the two top rods. After the smoke exhaust frame loses the restriction, it disengages from the installation frame, thereby facilitating the cleaning operation of the filter screen. The utility model provides another solution to this problem. Utility Model Content
