Description

Technical Field

[0001] This utility model relates to the field of smoke extractor technology, specifically to a novel smoke extractor. Background Art

[0002] A range hood is an essential piece of equipment in the kitchen, effectively and quickly removing cooking fumes to prevent smog from bothering cooks. Currently, range hoods can be categorized into those for household use and those for restaurant kitchens. Restaurant kitchen range hoods typically rely solely on internal filters to remove fumes. It's easy to see that this method is relatively ineffective, and the filters are prone to clogging after prolonged use. In such cases, the filters need to be removed, cleaned, or replaced before the range hood can be used normally again.

[0003] In summary, existing kitchen and restaurant exhaust fans still have significant shortcomings in their use. To address these issues, we propose a new type of exhaust fan. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a new type of smoke extractor that is suitable for use in restaurant kitchens. When in use, it can filter oil fumes more effectively and maintain a good filtration effect for a longer period of time, and is not easily clogged.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A new type of smoke extractor includes:

[0007] The machine casing includes a suction port, a smoke exhaust port, and a sewage discharge port. The machine casing is a cylindrical structure with both ends closed, and a suction port is provided at the center of the front end, a smoke exhaust port is provided at the rear end, and a sewage discharge port is provided at the bottom.

[0009] The smoke extraction fan is installed and fixed inside the smoke exhaust outlet.

[0010] As an improvement, an mounting ring is formed on the inner wall of the front end of the housing. After the end of the filter element is fitted onto the mounting ring, it is interference-fitted with the mounting ring. This allows for convenient installation of the filter element.

[0011] As an improvement, the filter element washing mechanism includes a motor, a water supply pipe, strip brushes, a transfer water tank, a water supply pipe, and a sealing plate. The water supply pipe is an L-shaped pipe closed at both ends. The horizontal section is connected to a motor fixed to the rear of the housing. A pair of strip brushes are fixed on the vertical section. The two strip brushes are movably connected to the inner and outer walls of the filter element, respectively. The inner side of the brush handle of the strip brush has a water supply cavity that communicates with the water supply pipe. The side wall of the brush handle covered with bristles has multiple spray holes that communicate with the water supply cavity. The rear side of the filter element is movably connected to a sealing plate fixed to the brush handle of the two strip brushes. The sealing plate blocks the rear opening of the filter element. The transfer water tank is an annular box with an open inner side. It is rotatably fitted onto the horizontal section of the water supply pipe. A water supply pipe that extends upward through the housing is connected to the side. Multiple water inlets located inside the transfer water tank are reserved on the horizontal section of the water supply pipe. It can wash the filter element, making it less prone to clogging and allowing it to maintain good filtration performance for a longer period of time.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] In use, this new type of filter cartridge features a filter cleaning mechanism that allows the filter cartridge to be cleaned directly after a period of use. If it is cleaned after each use, the filter cartridge will maintain a good filtration effect. Compared to existing range hoods, this naturally provides a better oil fume filtration effect. Furthermore, the filter cartridge is less prone to clogging and can maintain a good oil fume filtration effect for a long time. Attached Figure Description
