Cooking fume exhauster

Technical Field

The utility model relates to an oil smoke purifier, especially a range hood.

Background

The range hood has become one of indispensable kitchen household electrical appliances in modern families, and the range hood generally comprises a top suction type range hood and a side suction type range hood, and the top suction type range hood has increasingly wide application due to the advantages of neatness, lightness, small occupied space and the like. The top-suction range hood generally includes a smoke collecting hood, a fan housing located on the smoke collecting hood, and a volute, an impeller, and a motor for driving the impeller are installed in the fan housing.

In order to improve the effect of absorbing oil smoke, the existing ceiling-mounted range hood usually has a smoke guide plate arranged below the air inlet to move the negative pressure region downward and promote the absorption of oil smoke by using the wall attachment effect. The chinese patent with application number 202210480173.2 discloses a collection petticoat pipe, includes collection petticoat pipe body, still includes: the smoke collecting cavity is inwards sunken from the bottom of the smoke collecting hood body; the oil cup is arranged on the rear side of the bottom of the smoke collecting hood body; the front end of the smoke guide plate is arranged in the smoke collecting cavity in a turnover mode, and the rear end of the smoke guide plate is hinged with the smoke collecting cover body and at least partially extends to the position right above the oil cup.

However, for most families, the left and right cooking benches of the kitchen range rarely have the cooking condition at the same time, when the right (left) cooking bench is used for cooking, and the left (right) cooking bench is idle, the negative pressure area needs to be reasonably utilized, so that the negative pressure area can deviate to the right (left) side, and the oil smoke absorption effect on the right side of the range hood is improved. The current solution is usually to use two smoke guide plates, which results in a complex mechanism and increased cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art existence, provide a range hood, utilize the mounting structure of smoke deflector to conveniently realize removing about the smoke deflector, and then realize removing about the negative pressure zone, and then improve the oil absorption cigarette effect.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and to simplify the description, rather than to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, since the disclosed embodiments of the invention may be arranged in different orientations, these directional terms are for illustrative purposes only and should not be considered limiting, as "upper", "lower", and the like are not necessarily limited to directions opposite to or coincident with the direction of gravity. Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Referring to fig. 1 to 4, a range hood, which is a ceiling range hood, includes a smoke collecting hood 1, a fan frame 2 disposed on the smoke collecting hood 1, and a fan (not shown) disposed in the fan frame 2.

An air inlet 11 is arranged on the fume collecting hood 1, and a fume guide plate 3 is arranged below the air inlet 11. In order to facilitate the installation and movement of the smoke guide plate 3, the smoke collecting hood 1 is provided with a hook support 41, the upper surface of the smoke guide plate 3 is provided with a hook 42, and the hook 42 can adopt the prior art, such as that disclosed in the prior Chinese patent (201320774041.7-a range hood with a flow guide plate) of the applicant.

The hook bracket 41 includes a bracket body 411 and a support bar 412, the support bar 412 extending in a left-right direction (the left-right direction refers to a direction to a user in a mounted state when used). In this embodiment, the hook brackets 41 have four, and are disposed on the outer periphery of the intake vent 11. The corresponding hooks 42 are also four, one hook support 41 for each hook 42. The smoke guide 3 has a substantially rectangular shape, and hooks 42 are provided near four corners of the smoke guide 3. Two hook supports 41 arranged in the front and back are arranged corresponding to the left side of the smoke guide plate 3, and two hook supports 41 arranged in the front and back are arranged corresponding to the right side of the smoke guide plate 3. The support bar 412 of the left hanger bracket 41 may extend rightward from the corresponding bracket body 411, and the support bar 412 of the right hanger bracket 41 may extend leftward from the corresponding bracket body 411. That is, the support bars 412 of the hook brackets 41 on the left and right sides extend toward each other. Preferably, the support bar 412 extends horizontally. The hook 42 is hung on the support bar 412, so that the smoke guide plate 3 can move left and right along the support bar 412, and the left and right distribution of the negative pressure area is changed.

In order to prevent the hook 42 from falling off the support rod 412 when the support rod 412 moves, the end of the support rod 412 away from the support body 411 is provided with a stop piece 413, which can play a role of stopping the hook 42 and prevent the hook 42 from moving continuously in a direction away from the support body 411. The hook 42 moves between the holder body 411 and the stopper 413 and can stay at any position therebetween (by setting a friction force to maintain the position of the smoke guide plate 3), thereby realizing various positions of the movement of the negative pressure region.

Referring to fig. 4 and 5, the position of the hook 42 (left limit, the hook 42 on the left abuts against the support body 411 of the hook support 41 on the left) makes the smoke guide plate 3 approach the left side of the smoke collecting cover 1, which results in the negative pressure area moving and expanding to the right, when the cooking bench on the left is not used, and when the cooking bench on the right is used, the oil smoke absorption effect on the right can be ensured, similarly referring to fig. 6 and 7, the position of the hook 42 (right limit, the hook 42 on the right abuts against the support body 411 of the hook support 41 on the right) can ensure the oil smoke absorption effect on the left.

In the above embodiment, alternatively, the positions of the hanger bracket 41 and the hanger 42 may be interchanged.
