Technical Field

[0001] The utility model relates to the field of smoke exhaust fans, in particular to a self-filtering kitchen pipeline smoke exhaust fan. Background Technique

[0002] The kitchen pipeline smoke exhaust fan is a ventilation device specially designed for the kitchen, mainly used to remove the oil fume, peculiar smell, heat and moisture generated during the cooking process, so as to keep the kitchen environment clean and the air circulating. The fan quickly sucks away the oil fume generated in the kitchen through strong wind power, preventing the oil fume from accumulating in the kitchen and reducing the impact on the air quality.

[0003] However, most traditional kitchen pipeline smoke exhaust fans cannot effectively filter and intercept the oil fume, resulting in the accumulation of oil fume dirt on the pipeline and the fan blades, thus affecting the smoke exhaust efficiency of the kitchen pipeline smoke exhaust fan.

[0004] Therefore, the technicians in this field provide a self-filtering kitchen pipeline smoke exhaust fan to solve the problems raised in the above background technique. Content of the Utility Model

Then, the second layer of interception and adsorption of the oil fume is carried out through the aluminum filter screen composed of multiple filter meshes, so that the oil fume can be intercepted by the interception mechanism to a large extent. Finally, under the action of the cleaning mechanism, warm water or cleaning liquid is sprayed on the aluminum filter screen, and the newly adsorbed oil fume stains are cleaned through the flow of the liquid. The sewage is guided into the arc-shaped water storage channel under the action of the inclined plate and then discharged through the drain port, thus reducing the possibility of dirt formed by the accumulation of oil fume, improving the interception and filtration effect of the smoke exhaust fan, and further extending the service life of the smoke exhaust fan.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Referring to Figures 1-6 An embodiment provided by the present utility model:

[0037] A self-filtering kitchen duct smoke exhaust fan, comprising a duct shell 1. In the middle of the outer wall of the duct shell 1, a placement ring 2 is fixedly connected. On one side of the outer wall of the placement ring 2, a power connector 3 is fixedly connected. At the front end of the outer wall of the placement ring 2, a control panel 4 is fixedly connected, enabling the user to conveniently control the kitchen duct smoke exhaust fan through the control panel 4. At the upper end of the outer wall of the duct shell 1, a fixed flange 5 is fixedly connected, and by setting the fixed flange 5, the kitchen duct smoke exhaust fan is fixed at the required position. At the lower end of the inner wall of the duct shell 1, an interception mechanism 7 is fixedly connected. The interception mechanism 7 includes a placement rack 701.

At the lower part of the inner wall of the placement rack 701, a plurality of second annular inclined plates 705 are fixedly connected. At the center of the upper surface of the second annular inclined plate 705, a ventilation slot 706 is opened;

[0038] In the middle of the inner wall of the duct shell 1, a cleaning mechanism 8 is fixedly connected. The cleaning mechanism 8 includes a fixed ring 801, a solenoid valve 804, and a fixing plate 805. Inside the fixed ring 801, a shunt pipe 802 is fixedly connected. On the inner wall of the fixed ring 801, a plurality of nozzles 803 are fixedly connected. On the inner wall of the fixing plate 805, an arc-shaped water storage channel 806 is fixedly connected. At the rear end of the outer wall of the arc-shaped water storage channel 806, a drain port 807 is fixedly connected.

[0039] Compared with most traditional kitchen duct smoke exhaust fans, this kitchen duct smoke exhaust fan is provided with an interception mechanism 7 and a cleaning mechanism 8. Under the action of the first annular inclined plate 704 and the second annular inclined plate 705, the first layer of blocking and interception of oil fume is carried out, reducing the possibility of oil fume adsorbing on the inner wall of the duct shell 1 to form dirt. Then, the aluminum filters 702 composed of multiple layers of filters are used to carry out the second layer of interception and adsorption of oil fume, enabling the oil fume to be intercepted by the interception mechanism 7 to a greater extent. Finally, under the action of the cleaning mechanism 8, warm water or cleaning liquid is sprayed on the aluminum filters 702, and the just-adsorbed oil fume stains are cleaned through the flow of the liquid. The sewage is guided into the arc-shaped water storage channel 806 under the action of the inclined plate and then discharged through the drain port 807, thereby reducing the possibility of dirt formed by the accumulation of oil fume, improving the interception and filtration effect of this smoke exhaust fan, and further extending the service life of this smoke exhaust fan.

[0040] At the upper end of the inner wall of the shell 1, an exhaust mechanism 6 is fixedly connected. The exhaust mechanism 6 includes a housing 601, a stainless steel filter screen 602, a fixing frame 603, a servo motor 604, and a fan blade 605, so that the kitchen duct smoke exhaust fan can suck and discharge oil fume. The stainless steel filter screen 602 is fixedly connected to the upper and lower ends of the inner wall of the housing 601 respectively. The fixing frame 603 is fixedly connected to the middle of the inner wall of the housing 601. By setting the stainless steel filter screen 602, oil fume particles can be adsorbed, reducing the damage to the exhaust mechanism 6. The servo motor 604 is fixedly connected to the center of the upper surface of the fixing frame 603, and the fan blade 605 is fixedly connected to the output end of the servo motor 604, so that the servo motor 604 can control the fan blade 605 to form the required wind force. The inner wall of the placement rack 701 is threadedly fitted with a plurality of fixing bolts 703. By setting the fixing bolts 703, the user can disassemble the first annular inclined plate 704 and the second annular inclined plate 705 from the placement rack 701. The electromagnetic valve 804 is fixedly connected to the rear end of the outer wall of the placement ring 2, and the electromagnetic valve 804 is fixedly connected to the shunt pipe 802, so that the electromagnetic valve 804 can control whether to convey the required liquid into the shunt pipe 802.

[0041] Working principle: First, the device is fixed on the ventilation duct through the fixing flange 5, the power is turned on, and the electromagnetic valve 804 is connected to the warm water pipe or the cleaning liquid conveying pipe. Under the action of the exhaust mechanism 6, the oil fume generated under the device is sucked. The oil fume first passes through the first annular inclined plate 704 and the second annular inclined plate 705. Some oil fume particles will accumulate on the bottom surface of the annular inclined plate. The remaining oil fume particles are adsorbed under the interception of the aluminum filter screen 702 composed of multiple layers of aluminum material filter screens. Only the last part will be adsorbed on the inner wall of the shell 1 and the stainless steel filter screen 602. After use, the cleaning mechanism 8 is started. When the oil fume particles have not formed dirt, they will be melted by the warm water or cleaning liquid sprayed by the nozzle 803 to form sewage, and flow along the inner wall of the shell 1 or the first annular inclined plate 704 and the second annular inclined plate 705 into the arc-shaped water storage channel 806, and then the sewage is discharged through the drain port 807, so that the possibility of forming dirt is concentrated on the first annular inclined plate 704, the second annular inclined plate 705, and the arc-shaped water storage channel 806. Furthermore, the user only needs to clean the first annular inclined plate 704, the second annular inclined plate 705, and the arc-shaped water storage channel 806 to complete the cleaning and maintenance of the device.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
