Description

Technical Field

[0001] The utility model relates to the field of kitchens and bathrooms, in particular to a range hood that can be automatically raised and lowered. Background Art

[0002] Range hoods are used to absorb cooking fumes when cooking, but currently domestic range hoods are all fixedly installed, and the distance between the range hood and cooking utensils is also fixed. When users use cooking methods that produce a lot of oil smoke, such as stir-frying and frying, range hoods installed at conventional heights are difficult to absorb the oil smoke completely. Even if the air volume is increased, some oil smoke will still escape, and the oil fume absorption effect is not ideal. At the same time, the noise will also increase, affecting the user experience.

[0003] According to the above, the existing range hood structure needs to be further improved. Utility Model Content

DETAILED DESCRIPTION

[0036] In the description of the present invention, it should be understood that the directions or positional relationships indicated by “up”, “down”, “left”, “right”, “horizontal”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0037] See also Figures 1 to 6 An automatically elevating range hood 1 includes a drive mechanism 2, a lifting mechanism 3, and a range hood 4. The lifting mechanism 3 is movably mounted on and vertically connected to the drive mechanism 2. The lifting mechanism 3 includes a connecting plate 31 and guide rails 32 disposed on either side of the connecting plate 31. The side of the lifting mechanism 3 facing away from the guide rails 32 is connected to the range hood 4. The lifting mechanism 3 of this embodiment allows the range hood 4 to be adjusted in height. For cooking methods that produce a lot of oil smoke, such as stir-frying and deep-frying, the range hood 4 can be lowered to bring the air inlet 5 closer to the oil smoke, achieving better oil smoke absorption without increasing the air volume.

[0038] See also Figures 1 to 8 The lifting mechanism 3 further includes a slider 33 and a hook 34. The slider 33 is slidably mounted on the guide rail 32. The connecting plate 31 is connected to the guide rail 32 via the slider 33. The hook 34 is disposed on a side of the connecting plate 31 adjacent to the range hood 4. The range hood 4 is hooked to the connecting plate 31 via the hook 34. The connecting plate 31 has flanges 311 at its upper and lower sides, and the hook 34 is disposed between the flanges 311. In this embodiment, the connecting plate 31 is fixedly connected to the range hood 4 via the hook 34 and is connected to the left and right guide rails 32 via the slider 33, allowing the range hood 4 to be smoothly raised or lowered when adjusting its height.

[0039] See also Figures 7 and 8 To provide the power for lifting and lowering, the drive mechanism 2 includes a motor 21, a drive rod 22, and a moving block 23. The motor 21 is mounted above the drive rod 22 via a mounting plate 24. The moving block 23 is movably mounted on the drive rod 22 and is fixedly connected to the connecting plate 31. In this embodiment, the drive mechanism 2 uses the motor 21 and drive rod 22 to drive the moving block 23 in the direction of the drive rod 22, ensuring that the range hood 4 can rise and fall in a straight line.

[0040] See also Figures 7 and 8 In order to limit the moving direction of the movable block 23, a limit block 25 is provided on the lower side of the driving rod 22, and limit brackets 26 are provided on both sides of the driving rod 22. The limit brackets 26 extend from the mounting plate 24 to the limit block 25, and the movable block 23 is movably set on the limit brackets 26.

[0041] See also Figures 9 and 10 The range hood 4 includes an air inlet 5 and a range hood body 6 . The air inlet 5 is arranged at the lower side of the range hood body 6 . A through hole 61 is provided on the range hood body 6 . The range hood body 6 is hung on the hook 34 through the through hole 61 .

[0042] See also Figure 11 The range hood body 6 includes a cover plate 62 and side plates 63 provided on both sides of the cover plate 62 . The cover plate 62 and the side plates 63 together form the range hood body 6 with an open bottom.

[0043] See also Figures 9 to 11 The air inlet 5 includes a suction portion 7 and an oil baffle 8. The oil baffle 8 is tilted and positioned above the suction portion 7. Together, the suction portion 7 and the oil baffle 8 form an air inlet 5 with an upper opening. The range hood body 6 and the air inlet 5 are sealed to each other. The oil baffle 8 is provided with filter holes 81, which are evenly distributed throughout the oil baffle 8. The oil baffle 8 of this embodiment is used to separate oil smoke, causing oil droplets to condense on the oil baffle 8, while the smoke is drawn into the range hood 4 through the filter holes 81.

[0044] See also Figure 12 In order to collect the oil droplets, the suction part 7 includes an oil collecting plate 71, and an oil collecting groove 72 is provided on the lower side of the oil collecting plate 71. The oil collecting groove 72 is set as a concave cavity with an open top. An oil inlet hole 711 is provided on the oil collecting plate 71, and the oil collecting groove 72 is set on the lower side of the oil inlet hole 711.

[0045] See also Figures 13 to 18 The automatically liftable range hood 1 can be used in conjunction with the wall cabinet 9. When the range hood 4 is not in use, it can be stored in the wall cabinet 9. When it is needed, the range hood 4 can be pulled out of the wall cabinet 9 for use.

[0046] The present invention adjusts the height of the range hood 4 through the lifting mechanism 3, so that the air inlet 5 of the range hood 4 can be as close to the oil smoke as possible under different cooking methods. Therefore, the range hood 4 can better absorb oil smoke without increasing the air volume. When installed in conjunction with the wall cabinet 9, the range hood 4 can be extended out of the wall cabinet 9 when in operation and can be stored in the wall cabinet 9 when in storage, making the kitchen more tidy and coordinated. Compared with the existing technology, the automatic lifting range hood 1 of the present invention can adapt to various cooking methods and has a better oil smoke absorption effect.
