Description

Technical Field

[0001] This utility model relates to the technical field of kitchen exhaust equipment, and in particular to a kitchen exhaust equipment that facilitates centralized cleaning of oil stains. Background Technology

[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly remove the waste from the stove and the harmful fumes produced during cooking, expelling them outdoors, reducing pollution, and providing a safety guarantee for air purification. Therefore, range hoods are widely used in modern life.

[0003] When existing range hoods extract cooking fumes, grease forms along the path of the fumes. Due to their structure, this grease tends to accumulate on the inner wall of the range hood's fume collection hood, making it difficult to collect and process the fumes. This results in the fume collection hood becoming clogged with grease, affecting the range hood's efficiency and preventing it from effectively absorbing and expelling fumes from the kitchen. Utility Model Content

[0004] This utility model discloses a kitchen exhaust device that facilitates centralized cleaning of oil stains, mainly solving the problem that oil stains generated by existing range hoods are not easy to be centrally processed.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides a kitchen exhaust device that facilitates centralized cleaning of oil stains, including a smoke collection hood. Two inclined support plates are spaced apart on the smoke collection hood, and the gap between the two support plates forms an oil fume inlet. An oil stain guiding component is installed on the smoke collection hood at the position corresponding to the oil fume inlet.

[0007] An oil collecting cavity is formed between the smoke hood and the support plate. An oil collecting groove is provided below the oil collecting cavity of the smoke hood. Multiple oil guide holes are passed through the bottom of the oil collecting groove. A detachable oil collecting component is provided below the oil collecting groove of the smoke hood. L-shaped brackets are provided at both ends of the smoke hood corresponding to the oil collecting component. A sliding groove is formed between the L-shaped brackets and the surface of the smoke hood.

[0008] The oil collecting component is provided with a concave oil collection groove, and the multiple oil guide holes are all located within the range of the oil collection groove. Both ends of the oil collecting component are provided with sliders, and the sliders cooperate with the grooves.

[0009] In one embodiment, the L-shaped bracket is flexible, and a positioning hole is provided through the L-shaped bracket. The slider is provided with a positioning protrusion at the position corresponding to the positioning hole, and the positioning protrusion is adapted to the positioning hole.

[0010] In one embodiment, a guide pipe is installed in the oil guide hole, the end of the guide pipe protrudes out of the smoke collection hood, and a recessed relief groove is provided on the upper surface of the oil collection component corresponding to the position of the guide pipe.

[0011] In one embodiment, the oil sludge guiding assembly includes a guide frame with a guide groove extending through the upper and lower edges of the guide frame, and a plurality of first through holes extending through the guide frame.

[0012] In one embodiment, an isolation guide is installed on the flow guide frame at the position corresponding to the first through hole. A first isolation plate and a second isolation plate are respectively provided on the left and right sides of the isolation guide. The first isolation plate and the second isolation plate are staggered so that there is a ventilation gap between the ends of the first isolation plate and the second isolation plate away from the flow guide frame. A second through hole is passed through the isolation guide at the position corresponding to the first through hole. The first through hole and the second through hole are connected so that the oil collection chamber of the smoke hood is connected to the outside through the first through hole and the second through hole.

[0013] In one embodiment, the guide frame is provided with a raised mounting protrusion at the edge corresponding to the first through hole, and the mounting protrusion is adapted to the second through hole.

[0014] The advantages or beneficial effects of the above technical solution include at least the following: During the fume extraction process, the fumes are extracted through the fume inlet and the oil sludge guiding component. At this time, the fumes form oil sludge in the oil collection chamber. The oil sludge flows along the inner wall of the oil sludge guiding component and the fume hood to the oil collection tank, and then drips into the oil sludge collection tank of the oil collection component through the oil guide hole. When it is necessary to clean the oil sludge in a concentrated manner, the oil collection component can be directly removed through the sliding groove on the L-shaped bracket in cooperation with the slider of the oil collection component, so as to facilitate the centralized treatment of oil sludge. This can prevent the fume hood from being blocked by oil sludge and ensure the effective absorption and exhaust of fumes in the kitchen. Attached Figure Description

[0035] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0036] See Figures 1 to 3 This utility model provides a kitchen exhaust device that facilitates centralized cleaning of oil stains, including a fume hood 1. Two inclined support plates 2 are spaced apart on the fume hood 1, and the gap between the two support plates 2 forms an oil fume inlet 21. An oil stain guiding component 3 is installed on the fume hood 1 at the position corresponding to the oil fume inlet 21. A fume exhaust fan and a matching motor can be installed in the fume hood 1 for driving, thereby creating a negative pressure in the oil collection chamber 11 to achieve the function of extracting oil fumes.

[0037] An oil collecting cavity 11 is formed between the smoke hood 1 and the support plate 2. An oil collecting groove 12 is provided below the oil collecting cavity 11 in the smoke hood 1. Multiple oil guide holes 121 are passed through the bottom of the oil collecting groove 12. A detachable oil collecting component 4 is provided below the oil collecting groove 12 in the smoke hood 1. L-shaped brackets 13 are provided at both ends of the smoke hood 1 corresponding to the oil collecting component 4. A sliding groove 131 is formed between the L-shaped brackets 13 and the surface of the smoke hood 1.

[0038] The oil collecting component 4 is provided with a concave oil collection groove 41, and multiple oil guide holes 121 are located within the range of the oil collection groove 41. Both ends of the oil collecting component 4 are provided with sliders 42, and the sliders 42 cooperate with the grooves 131.

[0039] With the above structure, during the fume extraction process, the fumes are drawn out through the fume inlet 21 and the oil sludge guiding component 3. At this time, the fumes will form oil sludge in the oil collection chamber 11. The oil sludge flows along the oil sludge guiding component 3 and the inner wall of the fume hood 1 to the oil collection tank 12. Then, it drips into the oil sludge collection tank 41 of the oil collection component 4 through the oil guide hole 121. When it is necessary to clean the oil sludge, the oil collection component 4 can be directly removed through the sliding groove 131 on the L-shaped bracket 13 in cooperation with the slider 42 of the oil collection component 4, so as to facilitate the centralized treatment of oil sludge. This can prevent the fume hood 1 from being blocked by oil sludge and ensure the effective absorption and exhaust of fumes in the kitchen.

[0040] In one embodiment, see Figure 2 The L-shaped bracket 13 is flexible and has a positioning hole 132. The slider 42 has a positioning protrusion 43 corresponding to the positioning hole 132, and the positioning protrusion 43 is adapted to the positioning hole 132. In practical application, with the cooperation of the positioning hole 132 of the L-shaped bracket 13 and the positioning protrusion 43 on the slider 42, the oil collecting component 4 can be positioned when the slider 42 of the oil collecting component 4 is installed in the slide groove 131, so as to prevent the oil collecting component 4 from easily falling out of the slide groove 131. With the flexibility of the L-shaped bracket 13, the positioning protrusion 43 can be disengaged from the positioning hole 132 by pushing or pulling the oil collecting component 4, so that the oil collecting component 4 can be removed.

[0041] In one embodiment, see Figure 2 A guide pipe 14 is installed in the oil guide hole 121, and the end of the guide pipe 14 protrudes from the smoke hood 1. A recessed relief groove 44 is provided on the upper surface of the oil collecting component 4 corresponding to the position of the guide pipe 14. In practical applications, the guide pipe 14 can guide the oil in the oil collecting tank 12 to the oil collection tank 41, preventing oil from remaining on the outer wall of the smoke hood 1 through the edge of the oil guide hole 121. The relief groove 44 can prevent the oil collecting component 4 from being obstructed by the guide pipe 14 during installation and disassembly.

[0042] In one embodiment, see Figure 1 , Figure 4 , Figure 5 and Figure 6 The oil sludge guiding component 3 includes a guide frame 31 with a guide groove 311 extending through its upper and lower edges. Multiple first through holes 312 also extend through the guide frame 31. The lower edge of the guide frame 31 is embedded in the oil collection tank 12. In practical applications, the through-flow of the guide groove 311 allows oil sludge formed on the oil sludge guiding component 3 to flow along the guide frame 31 into the oil collection tank 12. The first through holes 312 allow external oil fumes to enter the oil collection chamber 11 through the first through holes 312.

[0043] An isolation guide 32 is installed on the flow guide frame 31 at the position corresponding to the first through hole 312. A first isolation plate 321 and a second isolation plate 322 are respectively provided on the left and right sides of the isolation guide 32. The first isolation plate 321 and the second isolation plate 322 are staggered so that there is a ventilation gap between the ends of the first isolation plate 321 and the second isolation plate 322 away from the flow guide frame 31. A second through hole 323 is passed through the isolation guide 32 at the position corresponding to the first through hole 312. The first through hole 312 and the second through hole 323 are connected so that the oil collection chamber 11 of the smoke hood 1 is connected to the outside through the first through hole 312 and the second through hole 323. In practical applications, the first isolation plate 321 and the second isolation plate 322 of the isolation guide 32 can isolate and block the first through hole 312, thereby increasing the contact area between the oil fumes passing through the first through hole 312 and the first isolation plate 321 and the second isolation plate 322. This allows the oil stains generated by the oil fumes to be adsorbed onto the first isolation plate 321 and the second isolation plate 322, and allows the oil fumes to flow along the first isolation plate 321 and the second isolation plate 322 into the oil collection tank 12.

[0044] The flow guide 31 has a raised mounting protrusion 313 on the edge corresponding to the first through hole 312, and the mounting protrusion 313 is adapted to the second through hole 323. In practical application, with the cooperation of the mounting protrusion 313 and the second through hole 323, the isolation flow guide 32 can be installed on the flow guide 31 at the position corresponding to the first through hole 312.

[0045] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0046] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
