Description

Technical Field

[0001] The present application relates to the technical field of range hoods, and in particular to a range hood. Background Art

[0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Range hoods use centrifugal fans installed inside the range hoods to absorb and exhaust oil fumes, and use filters to filter out some grease particles. Range hoods are mainly top-suction and side-suction types. Among them, top-suction range hoods use the principle of oil fume rising to create a negative pressure area directly above the stove to absorb and exhaust the naturally rising oil fume generated during cooking. However, when cooking with a small amount of oil fume, the oil fume above the pot is easily disturbed by the ambient air, causing the oil fume to escape to the surroundings, resulting in poor oil fume extraction effect. Currently, top-suction range hoods on the market often have a ring-suction butterfly wing plate below the air inlet, using the wall attachment effect to improve the oil fume extraction effect.

[0003] During the cooking process, many users often only use one side, or stir-fry on one side and cook soup on the other side. However, the existing range hoods cannot adjust the air volume on the left and right sides according to the usage of the stove or the difference in oil smoke generated, so as to match the user's cooking situation.

[0004] Therefore, it is necessary to provide an improved range hood to solve at least one of the above-mentioned problems in the prior art. Utility Model Content

[0006] Furthermore, the lifting assembly includes at least two lifting mechanisms; one end of the lifting mechanism is fixedly connected to the range hood body, and the other end of the lifting mechanism is connected to the guide plate; each of the lifting mechanisms can be used to drive the guide plate to move relative to the range hood body.

[0007] Furthermore, the lifting mechanism is rotatably connected to the guide plate.

[0028] It should be noted that the left air inlet 5 of the range hood is arranged corresponding to the left stove, and the right air inlet 6 is arranged corresponding to the right stove.

[0029] In some embodiments, the lifting assembly 21 includes at least two lifting mechanisms 211; one end of the lifting mechanism 211 is fixedly connected to the range hood body 1, and the other end of the lifting mechanism 211 is connected to the guide plate 22; each lifting mechanism 211 can be used to drive the guide plate 22 to move relative to the range hood body 1.

[0030] Specifically, the lifting mechanism 211 can be a lifting cylinder, the fixed end of the lifting cylinder is fixedly connected to the range hood body 1, and the telescopic end of the lifting cylinder is fixedly connected to the guide plate 22, so that the lifting cylinder can drive the guide plate 22 to achieve lifting movement, thereby adjusting the distance between the guide plate 22 and the corresponding stove, thereby improving the wall attachment effect between the oil smoke and the guide plate 22, and improving the smoking effect.

[0031] In other embodiments, the range hood further includes a control device, which can be electrically connected to the range hood body 1 and the guide plate adjustment assembly 2 respectively, so that the start and stop of the range hood body 1 can be controlled through the control device, and the movement of the guide plate adjustment assembly 2 can be controlled.

[0041] It should be noted that the oil collecting cup 3 is used to collect impurities such as grease left along the guide plate 22. The oil collecting cup 3 is always arranged below the guide plate 22. The oil collecting cup 3 can be raised and lowered simultaneously with the guide plate 22 through the telescopic mechanism 4, thereby improving the oil collecting effect of the oil collecting cup 3; at the same time, when the guide plate 22 rotates, the oil collecting cup 3 will not rotate with the guide plate 22 in order to prevent the oil inside it from flowing out.

[0042] In some embodiments, the telescopic mechanism 4 is detachably connected to the oil collecting cup 3 .

[0043] In the embodiment of the present application, the telescopic mechanism 4 and the oil collecting cup 3 are detachably connected to facilitate cleaning of the oil collecting cup 3.
