Abstract
Description
Technical Field
[0001] This utility model relates to the field of commercial kitchen equipment, and in particular to an integrated smart fume hood. Background Technology
[0002] In many industries such as catering and food processing, cooking generates a large amount of oily fumes. These fumes not only pollute the kitchen environment but may also harm human health. To effectively remove these fumes, fan equipment is widely used in the exhaust systems of various kitchens. However, during long-term operation, fans inevitably absorb impurities from the air, such as grease, dust, and food residue. As these impurities accumulate in the fan blades and ducts, the fan's operating efficiency gradually decreases. Typically, the fan needs to be removed from the fume hood for cleaning. Disassembling the fan requires significant manpower and time, leading to prolonged shutdowns of the kitchen exhaust system and disrupting normal production and business operations.
[0003] Therefore, there is a need to design an integrated smart fume hood that can automatically clean impurities on the fan without disassembly, is easy to use, and improves work efficiency. Utility Model Content
[0004] To overcome the shortcomings of existing integrated smart fume hoods, which typically require the fan to be removed from the hood for cleaning, disassembling the fan not only consumes a lot of manpower and time, but also causes the kitchen exhaust system to be shut down for a long time, affecting normal production and operation activities, this utility model provides an integrated smart fume hood that can automatically clean impurities on the fan without disassembly, making it convenient to use and improving work efficiency.

[0020] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.
[0021] An integrated smart smoke hood, such as Figures 1-4 As shown, the device includes a fume hood 1, a mesh plate 2, an air inlet 3, a smoke outlet 5, a filter 6, a fan 7, a purifier 8, a first baffle 9, a cleaning component, and a baffle component. The mesh plate 2 is connected to the inner side of the middle of the fume hood 1. The air inlet 3 is connected to the front of the fume hood 1. A sewage outlet 4 is opened at the rear of the fume hood 1. The smoke outlet 5 is connected to the upper side of the fume hood 1. The filter 6 is slidably clipped to the lower front and upper rear of the smoke outlet 5. The fan 7 is installed at the lower front of the smoke outlet 5. Three purifiers 8 are slidably clipped to the upper rear of the smoke outlet 5. The first baffle 9 is rotatably connected to the upper left of the smoke outlet 5. The first baffle 9 has a handle on its upper side for easy gripping. A cleaning component is located on the right side of the fume hood 1. A baffle component is located on the fume hood 1.
[0022] like Figure 4 and Figure 5 As shown, the cleaning assembly includes a motor 10, a reciprocating lead screw 11, a slider 12, and a spray frame 13. The motor 10 is connected to the upper right side of the front of the smoke outlet 5. The reciprocating lead screw 11 is connected to the output shaft of the motor 10. The reciprocating lead screw 11 is rotatably connected to the smoke outlet 5. The slider 12 is threadedly connected to the reciprocating lead screw 11. The slider 12 is slidably connected to the smoke outlet 5. The spray frame 13 is connected to the left side of the slider 12.
[0023] like Figure 1 , Figure 4 and Figure 5As shown, it also includes a shielding assembly, which includes a baffle 14, a guide rail 15, a frame 16, and a second shield 17. The baffle 14 is slidably connected to the lower part of the smoke hood 1, and the guide rail 15 is connected to the upper right side of the baffle 14. The frame 16 is connected to the inner right side of the smoke outlet 5, and the second shield 17 is slidably connected to the frame 16. The second shield 17 is slidably engaged with the guide rail 15.
[0024] When using this device, first install the exhaust duct 5 in the fume extraction area, then start the fan 7, allowing the fumes to enter the exhaust duct 5 through the air inlet 3, fume hood 1, mesh plate 2, and filter screen 6. The fumes are then filtered and purified by the purifier 8 and filter screen 6. When the fan 7 has been used for a long time and its rotating blades and filter screen have accumulated a lot of impurities, the second baffle 17 can be moved to the left, causing the guide rail 15 to move to the left, opening the second baffle 17 along the guide rail 15. This positions the guide plate 14 above the mesh plate 2. Then, the external conveying pipe is connected through the slider 12, and the motor 10 is started, driving the reciprocating screw 11 to rotate. This causes the slider 12 to move back and forth under the action of the screw, moving the spray frame 13 back and forth, thus cleaning the area. Water is sprayed from the spray frame 13 onto the fan 7, which automatically cleans the impurities on the fan 7 without disassembly, making it convenient to use and improving work efficiency. The wastewater dripping from the spray falls onto the guide plate 14 and is discharged from the wastewater outlet 4. After cleaning, the second baffle 17 is moved to the right to open, which drives the guide rail 15 to move to the right, so that the second baffle 17 moves backward along the guide rail 15 to close. The second baffle 17 covers the spray frame 13, which can easily cover the spray frame 13 and prevent oil fumes from adhering to the spray frame 13 and causing blockage. When it is necessary to clean and replace the purifier 8 and the filter screen 6, the filter screen 6 can be moved outward to remove it, and then the first baffle 9 can be rotated to open it, and then the purifier 8 can be removed.
[0025] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
