Abstract
The utility model relates to a negative pressure direct discharge type cooking fume exhausting fan, comprising a cover for a cooking fume exhauster, a spiral casing and a fan. The utility model is characterized in that the spiral casing is a pipeline whose middle part is salient; a guide bar which is parallelly fixed with the pipeline is arranged in one end of the pipeline; one end of the guide bar is tangential with the outer circumference of the blades of the fan and is identical with the rotary direction of the blades. The fan is a centrifugal fan which is made up of a motor and the blades. The connecting lines between the shaft of the centrifugal fan and both ends of the pipeline make a vertical angle. One end of the spiral casing, where the guide bar is arranged, is fixedly connected with the cover for a cooking fume exhauster. Due to the adoption of the structure of the utility model, the utility model has the advantages that cooking fume can be directly exhausted, without passing through the blades and the motor, the fan and the blades are seldom polluted, the load of the motor is small, and energy is saved.
Description
The utility model belongs to oily fume exhauster, is specifically related to a kind of negative pressure straight-line kitchen hood.
The kitchen hood of selling on the existing market all is to be made of oil smoke hood, spiral case, smoke exhaust pipe and the axial flow blower that is made of motor and fan blade basically, axial flow blower be fixed in the spiral case and the axle of axial flow blower parallel with spiral case air inlet axle.Therefore, during these kitchen hood fume exhausts, oil smoke need could be discharged through behind the blower fan, so its pollution to blower fan is very serious.
The purpose of this utility model provides a kind of to the minimum pollution of blower fan, and energy-conservation negative pressure straight-line kitchen hood.
For achieving the above object, negative pressure straight-line kitchen hood of the present utility model has oil smoke cover, spiral case, blower fan, it is characterized in that: (1) spiral case is the pipeline that the middle part has convex, there is the blower fan that is fixedly linked with it at the convex place of pipe, and the inner of pipeline has and the tangent gib block identical with its direction of rotation of draught fan impeller excircle.(2) centrifugal blower of blower fan for constituting by motor and fan blade.The axle of centrifugal blower and the vertical angle that is wired to of pipe ends mouth.(3) the spiral case end and the oil smoke hood that have a gib block is fixedly linked.
It is the tube connector of angle that one or both ends can be arranged between above-mentioned spiral case and the oil smoke hood, and this tube connector one end is connected with the oil smoke hood, and the other end is fixedlyed connected with the end that spiral case has gib block.
Because negative pressure straight-line kitchen hood of the present utility model adopts said structure, compare with existing kitchen hood, changed the air inlet of blower fan, so negative pressure straight-line kitchen hood of the present utility model when work, when being the blower fan rotation, oil smoke gas is discharged through the gib block straight line.And without fan blade and motor.Therefore, negative pressure straight-line kitchen hood of the present utility model has the following advantages:
(1) oil smoke gas needn't directly be discharged through fan blade and motor, so seldom producing centrifugal blower, pollutes in oil smoke, thus the hardship of removing cleaning from.
(2) fractional load that is exposed to outside the pipeline projection of the fan blade of centrifugal blower is big, and the fan blade that is positioned at the pipeline bossing is in negative pressure state, and load is little, so motor speed can significantly improve, power consumption is little.
In addition, adopt the angle tube connector between oil smoke cover and the spiral case, can also reduce and use height, make full use of the effective suction field, improve the suction rate, and do not influence operation.
Fig. 1: the utility model negative pressure straight-line kitchen hood partial sectional view.
The A of Fig. 2: Fig. 1 is to view.
Fig. 1, Fig. 2 have described an embodiment of the present utility model.It has oil smoke hood 1, one end is angle tube connector 2, spiral case 3 and centrifugal blower 4, groove 5.Angle tube connector one end is fixedlyed connected with the oil smoke hood, and the pipeline that the other end and spiral case have gib block fixes.Spiral case is the pipeline that there is projection at the middle part, and fixing with it and the gib block 6 parallel with pipeline are arranged in pipeline one end.With it fixing centrifugal blower is arranged, the vertical angle that is wired to of the axle of centrifugal blower and the pipe ends mouth of spiral case in the bossing of pipeline.
Claims (2)
1, a kind of negative pressure straight-line kitchen hood, comprise the oil smoke hood, spiral case and blower fan, it is characterized in that: (1) described spiral case is the pipeline that the middle part has projection, have parallel with pipeline and fixing with it gib block in one end of pipeline, gib block one end is tangent and identical with its direction of rotation with impeller of blower outer garden week; (2) centrifugal blower of described blower fan for constituting by motor and fan blade; (3) axle and the vertical angle that is wired to of pipe ends of centrifugal blower; (4) the spiral case end and the oil smoke hood that have a gib block is fixedly linked.
2, negative pressure straight-line kitchen hood according to claim 1 is characterized in that: described oil smoke hood and spiral case have and are fixedly connected with angle between gib block one end and take over.
