[0002] A smoke exhaust fan is a machine that can quickly remove odors, high temperatures, and oily fumes generated during food processing in the kitchen. This machine is characterized by its good high-temperature resistance and high efficiency. The fan impeller is one of the essential parts of a smoke exhaust fan. When the fan impeller is used for a long time, it needs to be cleaned to prevent oil stains from adhering to the impeller and affecting the smoke exhaust effect.

[0003] Currently, most impeller cleaning methods involve cleaning personnel using handheld spray guns and cloths to rinse and wipe various parts of the impeller. However, this method of handheld spray guns and cloths can easily cause high-pressure cleaning agents and oil to splash, affecting the cleaning environment and potentially entering the eyes or other sensitive areas of the cleaning personnel, posing a safety hazard. Furthermore, it increases the workload for cleaning personnel, making it inconvenient for cleaning and failing to meet customer needs.

[0004] Therefore, those skilled in the art have provided a kitchen exhaust fan impeller cleaning device to solve the problems mentioned in the background art. Utility Model Content

A rotary motor 9 is fixedly installed at the bottom of the inner cavity of the concave plate 5. The output end of the rotary motor 9 passes through the concave plate 5. The mold plate 5 is fixedly connected to the shaft 6. Heating plates 10 are fixedly installed on both the left and right sides of the inner cavity of the heating box 1. Support components 11 are provided at the four corners of the bottom of the heating box 1. A drain pipe 13 is connected to the bottom of the left side of the heating box 1. One end of the drain pipe 13 is threadedly connected to a pipe cap. Guide rods 14 are fixedly connected to the left and right sides of the top of the lifting plate 4. The top of the guide rods 14 extends to the top of the concave frame 2. Slide cylinders 15 are embedded on both the left and right sides of the top of the concave frame 2. The inner surface of the slide cylinder 15 is slidably connected to the outer surface of the guide rod 14. A toggle plate 16 is provided on both the left and right sides of the bottom of the limiting plate 7. The connection between the toggle plate 16 and the limiting plate 7 is welded.

[0033] In this embodiment: By setting up a concave plate 5, a rotating shaft 6, a limiting plate 7, a positioning plate 8, and a rotary motor 9, the present invention can easily clamp and limit the rotation of the impeller. By setting up a concave frame 2, an electric cylinder 3, and a lifting plate 4, the impeller can easily enter and exit the heating box 1. By setting up the heating box 1 and the heating plate 10, the rotating impeller can be steamed and cleaned. By setting up the above structure, the impeller can be easily cleaned, thereby meeting the customer's cleaning needs, avoiding oil splashing, environmental pollution, and safety hazards.

[0034] Example 2:

[0035] Reference Figure 1 , Figure 2 and Figure 3 The support assembly 11 includes a stud 111, the top of which is fixedly connected to the connection of the heating box 1, a support cylinder 112 is threadedly connected to the outer surface of the stud 111, a caster wheel 113 is movably connected to the bottom of the stud 111, a locking plate is provided on one side of the caster wheel 113, and a reinforcing plate 12 is fixedly connected to the bottom of the support cylinder 112.

[0036] In this embodiment: By setting studs 111, support cylinders 112 and casters 113, the present invention can move and support the device, and at the same time adjust its horizontal state.

[0037] The implementation principle of this utility model is as follows: When in use, the staff moves the device to the designated cleaning area using the universal wheels 113. Then, the staff rotates the support cylinders 112 in sequence, so that the support cylinders 112 drive the reinforcing plate 12 to rotate and move downward on the outer surface of the stud 111 to contact the ground. Thus, the four support cylinders 112 and the reinforcing plate 12 work together to support the device and adjust its horizontal state.

[0038] Next, the staff connected the device to the mains power. When it was necessary to clean the fan impeller, the staff added a certain amount of water to the inner cavity of the heating box 1. Then, the staff activated the external controller of the heating plates 10 on both sides, so that the heating plates 10 on both sides were energized and heated, thereby heating the water in the inner cavity of the heating box 1. At the same time, the staff moved the impeller, so that the impeller hub was inserted into the outside of the rotating shaft 6. Meanwhile, the top of the impeller was tightly fitted with the positioning plate 8. Then, the staff rotated the moving limit plate 7, so that the limit plate 7 moved upward on the outer surface of the rotating shaft 6 and pressed against the impeller, thereby clamping and limiting the impeller.

[0039] Next, the operator activates the external controller of the electric cylinder 3, causing the telescopic end of the electric cylinder 3 to move the lifting plate 4 downwards. The lifting plate 4 then moves the concave plate 5 downwards, which in turn moves the rotating shaft 6 downwards. This causes the rotating shaft 6 to insert the impeller into the hot water inside the heating chamber 1, where the hot water softens and sterilizes the oil on the impeller surface. Then, the operator activates the external controller of the rotary motor 9, causing the output end of the rotary motor 9 to rotate the rotating shaft 6. The rotating shaft 6 then rotates the impeller, allowing the rotating impeller and the high-temperature cleaning water to work together to remove the oil, thus cleaning the impeller. This device is simple to operate and easy to use, meeting customer cleaning needs while preventing oil splashing, environmental pollution, and potential safety hazards.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
