The current hotel type apartment is limited by the floor height of 1.9m, and a range hood with small height and size is required. Referring to fig. 4, although the height of the existing range hood (the overall height of the smoke collecting hood 1 'and the air rack 2') can be 400mm, the overall height is at least more than 600mm because the air outlet hood 5 'and the smoke exhaust pipe 6' are also arranged above the range hood, and the height of the kitchen floor cabinet is 800mm, so that the distance from the range hood to the table top of the cabinet is only 500mm at most. However, the suspension height of a normal European-style range hood should be 650-750 mm, but due to the limitation of floor height of hotel apartments, the range hood can be installed only by sacrificing the suspension height and shortening the distance from the range hood to a cabinet.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, provide one kind and need not to sacrifice range hood's hanging height, the less range hood of volume.
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, sets up the fan frame of collection petticoat pipe top and sets up the fan in the fan frame, the fan includes air intake and air outlet, its characterized in that: the air inlet of the fan is transversely arranged and faces downwards, the air outlet of the fan is longitudinally arranged and faces to the side, and the smoke collecting hood is at least provided with a control switch which can control the operation of the range hood at the front part and the rear part respectively.
In order to realize hand back triggering, each control switch comprises at least two photoelectric sensors which are arranged at intervals left and right, and the distance between every two adjacent photoelectric sensors is not less than 25 mm.
In order to realize air outlet on the left side or the right side of the fan frame, a through hole communicated with an air outlet of the fan is formed in the left side or the right side of the fan frame.
In order to realize the connection with the public flue, an air outlet cover communicated with an air outlet of the fan is arranged at the through hole on the fan frame.
In order to control the range hood conveniently, control switches are arranged on the periphery of the bottom of the smoke collecting cover.
Compared with the prior art, the utility model has the advantages of: the fan is transversely arranged, so that the longitudinal occupied space of the fan frame is reduced, the longitudinal height of the range hood is reduced, and the suspension height of the range hood is increased; the front side and the rear side of the fume collecting hood are respectively provided with a control switch for controlling the range hood, so that the range hood supports bidirectional installation and use of the front side and the rear side; the control switch is provided with the photoelectric sensors at intervals, so that a user can conveniently control the range hood by using the back of the hand without being influenced by oil on the hand or a shovel held in the hand.

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 and 2, 4 and 5, a range hood is a ceiling range hood, and includes a fume collecting hood 1, a fan frame 2 disposed above the fume collecting hood 1, and a fan 3 disposed in the fan frame 2, where the fan 3 includes an air inlet 31 and an air outlet 32. In order to reduce the height of the range hood, the air inlet 31 of the fan 3 is transversely arranged and faces downwards, and the air outlet 32 of the fan 3 is longitudinally arranged and faces to the side, so that the fan 3 which is transversely arranged as a whole is formed. Through the fan 3 of horizontal arrangement, the whole height of fan 3 has been reduced from this to reduced the vertical occupation space of fan frame 2, reduced range hood's vertical height, increased range hood's suspension height, solved among the prior art because of range hood's vertical height overlength makes the too low problem of suspension height when installing.
Referring to fig. 2, a through hole 21 communicated with an air outlet 32 of the fan 3 is formed at the left side or the right side of the fan frame 2. An air outlet cover 5 communicated with an air outlet 32 of the fan 3 is arranged at the through hole 21 on the fan frame 2.
Referring to fig. 3 and 5, in order to support the range hood to be installed and used on both the front side and the rear side, the fume collecting hood 1 is provided with control switches 4 capable of controlling the operation of the range hood at least on the front portion and the rear portion of the range hood, each control switch 4 includes at least two photoelectric sensors 41 arranged at intervals left and right, and the distance between two adjacent photoelectric sensors 41 is not less than 25 mm. In this embodiment, in order to facilitate the operation, the control switches 4 are disposed around the bottom of the fume collecting hood 1, and the photoelectric sensors 41 are spaced around the bottom of the fume collecting hood 1.
Because hotel formula apartment common flue sets up on range hood's left side or right side, the range hood of this embodiment can be according to actual conditions, confirms orientation left side or right side of air outlet 32 of fan 3 for discharge fume 6 connects on the left side or the right side of fan frame 2, thereby decides collection petticoat pipe 1 front side or dorsal part installation use.
The sensing distance of the photosensor 41 is less than 10mm (the vertical direction is the sensing direction of the photosensor). The traditional switch is touched and sensed by finger belly, but the range hood is very inconvenient to operate when cooking or other things exist in hands. In the embodiment, after the range hood is powered on, each of the photoelectric sensors 41 starts to detect, the range hood needs to be turned on or off, at least two adjacent photoelectric sensors 41 need to be simultaneously detected to jump, and meanwhile, if no other photoelectric sensor 41 is triggered within a certain time (e.g., 0.5s), the range hood is turned on or turned off. The width of a single finger of a person can not reach 25mm, so that the back of the hand can be used for touching the control switch 4 if the range hood needs to be operated, and the range hood is not influenced by oil on the hand or a shovel held in the hand. Because the photoelectric sensor 41 is installed on the bottom of the smoke collecting hood of the range hood on one circle, the control switch 41 supports the forward and reverse installation of the range hood. In addition, under the condition that the range hood is started, the sensors are sequentially triggered from left to right, so that the range hood is shifted up, and the sensors are sequentially triggered from right to left, so that the range hood is shifted down.
According to the range hood installed in the mode, the smoke exhaust pipe 6 is connected to the left side or the right side of the fan frame 2 instead of being connected to the top of the fan frame 2 in the prior art, so that the overall height of the smoke exhaust pipe 6 and the range hood can be 300, the distance between the smoke exhaust pipe 6 and a cabinet is 50mm, and the suspension height of the range hood is 750mm, so that the range hood meets the installation requirement.
