Description

Fume exhaust fan

Technical Field

The utility model belongs to the technical field of kitchen appliances and specifically relates to 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 more and more extensive application due to the advantages of neatness, lightness, small occupied space and the like. The top-suction type range hood generally includes a fume collecting hood, a fan housing located on the fume collecting hood, and a volute, an impeller, and a motor for driving the impeller are installed in the fan housing.

Chinese utility model patent like application number 201320774041.7 discloses a range hood with guide plate, including collection petticoat pipe and guide plate, be equipped with the air intake on the collection petticoat pipe, the guide plate is just to the air intake.

The ceiling type range hood has a poor oil fume suction effect due to the problem of the hanging height. In order to promote the effect of the range hood, the better proposal is that the smoke exhaust capacity around the smoke collecting cavity of the range hood is increased by adding the smoke guide plate below the smoke collecting cover, but the problems brought simultaneously are: because the oil smoke will collide the smoke guide plate and then pop out when the oil smoke is more, the phenomenon that part of the oil smoke escapes towards the front side user direction can occur.

In order to improve the phenomenon of oil smoke escape, holes are formed in the smoke guide plate, but the problem of great pressure relief around the smoke guide plate is caused after the holes are formed, so that the oil smoke absorption effect around the guide plate is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that not enough to above-mentioned prior art provides a range hood, can improve the phenomenon that the oil smoke orientation escaped to the front side user direction to and prevent the pressure release problem because of trompil appears on the guide plate.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a range hood, includes collection petticoat pipe and smoke deflector, the main air intake has been seted up on the collection petticoat pipe, smoke deflector is located main air intake below, its characterized in that: the position that leads on the cigarette board, be close to cigarette board front side is provided with the auxiliary power device who is used for the air current suction of leading cigarette board below to the cigarette board top, auxiliary power device is including lieing in the supplementary air intake of leading cigarette board below and lieing in the supplementary air outlet of leading cigarette board top, supplementary air intake extends in left right direction.

In order to achieve the best smoke suction and exhaust effect of the auxiliary power device, a case is arranged above the smoke collection cover, a main fan is arranged in the case, an air inlet of the main fan faces forwards, and an auxiliary air outlet of the auxiliary power device can correspond to the space between the air inlet of the main fan and the inner wall of the front side of the case.

Preferably, the auxiliary power device may be a cross-flow fan or an axial-flow fan.

In order to effectively prevent the oil smoke from escaping towards the direction of a user, the auxiliary air inlet of the auxiliary power device extends towards the front side direction of the range hood.

In order to realize the best smoke suction and exhaust effect of the auxiliary power device, the auxiliary power device is arranged on the smoke guide plate and corresponds to the middle position of the main air inlet in the left-right direction, and the length of the auxiliary power device is smaller than that of the main air inlet in the left-right direction.

Compared with the prior art, the utility model has the advantages of: through setting up auxiliary power device near smoke deflector front side, not only can prevent only to lead to the problem that smoke deflector smoking effect all around descends because of pressure release by a wide margin after trompil on smoke deflector, but also can improve the phenomenon that the oil smoke escaped to the user direction behind the striking smoke deflector. The auxiliary air inlet is arranged in a left-right extending mode, the smoking range of the front side of the range hood is expanded, and the auxiliary power device can rapidly suck away oil smoke escaping towards the direction of a user.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

For convenience of description, in this specification, "front", "rear", "left", "right", "up" and "down" refer to directions of the extractor hood relative to a user when in use.

Referring to fig. 1, a range hood, which is a ceiling range hood, includes a fume collecting hood 1, a cabinet 4 disposed above the fume collecting hood 1, and a fume guide plate 2 disposed below the fume collecting hood 1.

Referring to fig. 2 to 4, the smoke collecting hood 1 is provided with a main air inlet 11, and the smoke guide plate 2 is located below the main air inlet 11. An auxiliary power device 3 for sucking the airflow below the smoke guide plate 2 to the upper part of the smoke guide plate 2 is arranged on the smoke guide plate 2 and close to the front side of the smoke guide plate 2. In order to arrange the auxiliary power device 3 on the smoke guide plate 2, a through hole 21 is arranged on the smoke guide plate 2, and the auxiliary power device 3 is arranged in the through hole 21 and is fixedly connected with the smoke guide plate 2. Set up auxiliary power device 3 and be close to 2 front sides of smoke deflector, not only can prevent only to lead to the problem that smoke effect all around of smoke deflector 2 descends because of pressure release by a wide margin after trompil on smoke deflector 2, but also can improve the phenomenon that the oil smoke escaped to user's direction after striking smoke deflector 2.

The auxiliary power unit 3 includes an auxiliary air inlet 31 located below the smoke guide plate 2, and an auxiliary air outlet 32 located above the smoke guide plate 2.
