Description

Technical Field

[0001] This utility model relates to an integrated oil fume purification machine, specifically a self-cleaning integrated oil fume purification machine, belonging to the technical field of kitchen oil fume treatment equipment. Background Technology

[0002] An oil fume purifier is a device for treating oily fumes and exhaust gases. It is mainly used for the purification and treatment of low-altitude oily fumes emitted from kitchens. It is used in hotels, restaurants, eateries, schools, government offices, factories, and other places, as well as in food frying and cooking industries.

[0003] A self-cleaning integrated oil fume purification machine disclosed in Chinese patent application publication CN221548757U includes a body with a grid plate inclinedly arranged on the bottom surface of the body. The grid plate has an oil fume inlet hole inside, and a cleaning kit is arranged on the bottom surface of the grid plate. The top of the cleaning kit abuts against the grid plate. The grid plate has a rectangular structure, a first sliding groove is arranged on the top of the grid plate, and an oil collection box is arranged on the bottom of the grid plate. Compared with the prior art, the above technical solution has a rectangular grid plate structure, and the cleaning kit is also suitable for cleaning rectangular surfaces, making it more suitable for the operating environment of existing equipment in the industry and having a wider range of applications. However, the above technical solution can only clean the surface of the grid plate where oil fumes enter by sweeping the surface of the grid plate through a moving liquid distribution rod.

[0038] Please refer to this carefully. Figure 3The upper surface of the mounting ring 401 is fixedly connected with support columns 403 arranged in a circular pattern at equal intervals. The tops of several support columns 403 are fixedly connected with an oil fume filter 404. The oil fume filter 404 fixed on the support columns 403 can filter and purify the oil fume again, thereby improving the purification effect of the integrated oil fume purification machine.

[0039] In use, the following steps are taken: First, connect the main body 1 of the range hood, the first water pump 202, the electrostatic dust collection plate 206, the electric slide rail 207, the second water pump 208, the centrifugal fan 302, the electric water nozzle 304, the PTC heater 306, and the micro drain pump 8 to the power supply. When it is necessary to use the self-cleaning range hood to purify the fumes and automatically clean its interior, first manually install the range hood above the kitchen gas stove, and connect the output end of the exhaust pipe 307 to the external exhaust channel, so that the fumes purified by the range hood can be discharged into the atmosphere.

[0040] Next, by manually pulling the sealing plug 10 inside the water inlet pipe 9, the sealing plug 10 can be pulled out of the water inlet pipe 9, allowing the water that needs to be cleaned inside the integrated fume purifier to be transported to the water tank 201 through the water inlet pipe 9. When using the integrated fume purifier to purify fumes, the power supply of the centrifugal fan 302 is controlled by the main body 1 of the fume hood, which drives the rotating fan blades 303 to rotate at high speed, transporting the air inside the main body 1 of the fume hood to the outside through the exhaust pipe 307, thereby enabling the main body of the fume hood to purify fumes. The negative pressure generated inside the range hood 1 allows the oil fumes produced by the gas stove to be drawn into the range hood 1. The fumes then pass through the detachable grille 402 and the oil fume filter 404 for pretreatment, causing the oil to be absorbed into the oil fume filter 404 and flow into the interior of the range hood 1. The oil fumes pass through the pre-filter 205 and the electrostatic dust collection plate 206 in the mounting bracket 204 to adsorb the particulate matter and dust. The purified oil fumes are then discharged through the fan mounting box 301 into the exhaust pipe 307.

[0041] By setting the program, the automatic cleaning structure of the integrated fume purification machine needs to be used to clean its interior at regular intervals. This involves using the first water pump 202 to spray water from the water tank 201 through the inclined spray head 203 onto the inner wall of the main body 1 and the surface of the pre-filter 205 for easy cleaning. The electric slide rail 207 drives the second water pump 208 to move, allowing it to spray water from the water tank 201 through the spray nozzle 209 onto the outer surface of the electrostatic dust collection plate 206 for further cleaning. Finally, the electric water nozzle 304 draws water from the water tank 201 for spraying. The oil stains on the surface of the rotating fan blades 303 are cleaned by moving them to the outside of the rotating fan blades 303. After cleaning, the power of the micro drain pump 8 is controlled to use the power provided by the micro drain pump 8 to pump the oil stains and sewage at the bottom of the range hood body 1 to the outside for collection and treatment through the drain pipe 7. By controlling the power of the centrifugal fan 302 and the PTC heater 306, the centrifugal fan 302 can drive the rotating fan blades 303 to rotate in the opposite direction and blow air into the range hood body 1. The PTC heater 306 can also heat the surrounding air, so as to facilitate the drying of the inside of the integrated range hood with hot air.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
