Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen electrical equipment, and more specifically, particularly relates to a commercial kitchen smoke exhaust machine. Background Art

[0002] Commercial kitchens are quite common nowadays, especially in Chinese restaurants and canteens. Users will use cooking utensils to prepare dishes in commercial kitchens. Since smoke is more likely to be generated in the process of cooking, smoke exhaust fans are generally installed above the cooking utensils to absorb and discharge the smoke to ensure the air environment in the kitchen.

[0003] At present, when installing commercial kitchen range hoods, the range hood is generally installed on the wall, and then the exhaust pipe is installed to the exhaust port on the top of the range hood and sealed with tin foil, and finally the exhaust pipe is passed through the outside of the wall. However, fallen leaves, dust and other debris outside the wall, and even biological organisms can easily enter the interior of the range hood through the exhaust pipe, affecting the normal use of the range hood.

[0004] The existing Chinese patent publication number is CN209840223U, which discloses a kitchen smoke exhaust machine, including a smoke exhaust machine body and a smoke exhaust pipe, one end of the smoke exhaust pipe is movably mounted with a fixed sleeve, one side of the bottom of the inner cavity of the fixed sleeve is provided with a groove, the middle of the groove is movably mounted with a gear, the gear is meshed with a toothed disc, the toothed disc is fixedly sleeved on the outside of a movable rod, one end of the movable rod is movably sleeved with one side of the inner cavity of the groove, and a baffle is fixedly mounted on one side of the movable rod, and a load-bearing block is fixedly mounted on one side of the top of the baffle. The kitchen smoke exhaust machine, through the coordinated use of the baffle, the fixed sleeve and the movable rod, blocks the smoke outlet when the smoke exhaust machine is not working, preventing debris from entering the smoke exhaust machine along the smoke exhaust pipe, and at the same time, the gear and the toothed disc ensure that the two baffles rotate upward at the same time, and the load-bearing block and the groove ensure that the baffle can automatically fall back to the smoke outlet, thereby improving practicality. When the above-mentioned range hood is actually used, the wind carrying oil smoke in the exhaust pipe will continuously blow the baffle when the range hood is working, making it easy for kitchen oil smoke to adhere to and accumulate on the baffle, thereby reducing the exhaust efficiency. In addition, excessive accumulation of oil smoke can easily breed bacteria, which is not conducive to kitchen hygiene.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a commercial kitchen smoke exhaust fan is provided to achieve a more practical purpose. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a commercial kitchen smoke exhaust machine, which is achieved by the following specific technical means:

[0015] 1. The circular baffle, torsion spring shaft and smoke exhaust pipe are used in coordination in the utility model. When the smoke exhaust machine is not working, the torsion spring shaft is used to drive the circular baffle to rotate until it overlaps with the inner wall of the smoke exhaust pipe, thereby blocking the smoke outlet and preventing debris from entering the smoke exhaust machine through the smoke exhaust pipe. At the same time, a cleaning liquid is placed in the cleaning box, and the valve is opened regularly. The cleaning liquid can be sprayed out through the nozzle to wash the oil stains attached to the circular baffle. The rotating shaft is then driven to rotate by the motor, thereby driving the two U-shaped frames to rotate back and forth on the front and rear sides of the circular baffle. The sponge block inside the U-shaped frame is used to wipe and clean the front and rear end surfaces of the circular baffle, thereby improving practicality.

[0016] 2. By setting up a collection pipe, a collection box, a connecting plate and a fixed plate for use together, the sewage or oil flowing down the circular baffle can enter the interior of the collection box along the two collection pipes for collection. The connecting plate can be removed from the fixed plate by screws and nuts, so that the collection box can be removed from the connecting pipe sleeve. The collection box can be disassembled and cleaned regularly, thereby improving the use effect of the collection box. BRIEF DESCRIPTION OF THE DRAWINGS
