Abstract
A double speed-varying part for exhaust channel is composed of a comic casing with big top end, and an air draught channel with air inlet and outlet. The internal diameter of said air draught channel is gradually reduced from air inlet to air outlet. Its advantages are simple structure and high exhaust effect.
Description
Technical field:
The present invention relates to a kind of Double speed transmission part of the exhausting duct that in the exhast duct air-flow is played chronotropic action that is installed in.
Background technology:
The component for variable-pressure and the diversion component that use in the existing transformation class exhast duct, there is following defective in its structure design: component for variable-pressure and diversion component are installed in respectively on two of exhast duct or three tube walls, because the issuable error of installing and locating can influence the air draft effect, also is inconvenient to install; Simultaneously, the air-flow that rises in the exhast duct has from the transformation venturi and passes through, and also has to pass through from the gap between diversion component, component for variable-pressure and the duct wall, and the air-flow of multiply different in flow rate compiles, and produces turbulent flow, also can influence the air draft effect.Wreak havoc accident having stood SARS, especially had Hong Kong to wash in a pan two cross-infections such as big garden and The People's Hospital of Peking University's courtyard, cause after the lesson of epidemic situation diffusion, people will pay close attention to the cross pollution of the floor up and down that the kitchen exhast duct causes more.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art and provide a kind of air-inducing passage and speed change side are attached together to be one, simple in structure, easy for installation, Double speed transmission part of the exhausting duct that air draft is effective, the ingredient of two speed change parts gives processing respectively, attach together then and be one, then more easy.
Technical scheme of the present invention is: comprise housing, the outer shape of housing is the big cone in little top, bottom, and housing comprises speed change side, air intake side and end face, is provided with air-inducing passage in housing.Air-inducing passage be shaped as the kettle mouth shape air-inducing passage that reduces gradually to the air outlet aperture by air intake, air outlet is arranged on the end face of housing, air intake is arranged on the air intake side.

The profile of housing of the present invention is the big cone in little top, bottom, as if the monocline face timber wedge that the carpenter uses, last thick point down, be similar to the right-angled triangle of handstand, the bevelled side of two speed change parts is the speed change side, the inboard of speed change side is chewed the shape air-inducing passage or is induced duct for kettle, the air intake of induced duct is in the vertical side of two speed change parts, air outlet is at the end face of two speed change parts, the induced duct aperture is reduced to air outlet gradually by air intake, the housing of two speed change parts, the speed change side, kettle is chewed the end, kettle is chewed head and is given processing respectively and attach together then and be one, giving processing mode and can be housing and kettle chews head and is processed as one, housing and kettle are chewed head and kettle and are chewed the end and be processed as one, housing and speed change side are processed as one, housing and speed change side and kettle are chewed the end and are processed as one, it can also be the speed change side, kettle is chewed the end and is processed as one, more than the various processing modes that give, attach together at last and be two speed change parts.The speed change side is made of inclined-plane and vertical plane, inclined-plane and vertical plane are with the cambered surface smooth transition, cambered surface can be made in the inclined-plane of speed change side, can be cambered surface also with whole speed change side, can also be an inclined-plane with whole speed change side, the upper end that kettle is chewed a work plane is a perpendicular, the lower end is the cambered surface by air intake upper edge and perpendicular smooth transition, kettle is chewed the upper end of head can make the inclined-plane that parallels with the speed change side, kettle is chewed head can be hollow object, also can make solid, kettle is chewed the end toply is the cambered surface from induced duct air intake lower edge to speed change side smooth transition, this cambered surface also can be used as plane or inclined-plane, and it is that thin shell piece also can be made solid that kettle is chewed the end.
The operating principle of two speed change parts is: 1., two speed change parts pack that air intake that exhast duct, its vertical side be adjacent to tube wall and air-inducing passage is communicated with the air outlet of exhast duct into and with screw fastening after, the speed change side of two speed change parts with the tube wall of its face has been formed one and little gas channel greatly down, because the cause on inclined-plane, the taper hole that this gas channel reduces gradually for section from bottom to top.Rise to two speed change parts from the air-flow of exhast duct bottom, enter gas channel, air-flow continues to rise, speed is accelerated gradually, up penetrate to air outlet, this moment is fastest, static pressure is very little, even reach negative pressure, at same horizontal plane and immediately in the vicinity air-inducing passage air outlet in this negative pressuren zone, if cutting out, do not use by the smoke exhaust ventilator in the kitchen in this floor room, the air-flow that penetrates from gas channel not only can not recharge face and can produce the suction use to it to air-inducing passage, because the upper end of speed change side is that one section vertical plane is parallel with the tube wall on its opposite, constitute straight hole, the air-flow that penetrates from gas channel not only can scattering but also is keep-uped pressure steadily, helps air-flow and continues to rise.More than effect is exactly one of speed change of so-called two speed changes.2., another chronotropic action of air-inducing passage, kitchen exhaust gas enters air-inducing passage, chewing shape air-inducing passage to air outlet by kettle up discharges, because the air-inducing passage aperture is by air intake reducing gradually to air outlet, the air-flow with certain blast that smoke exhaust ventilator is sent into flow velocity in the air-inducing passage hole is accelerated gradually, to air outlet place speed maximum, static pressure is very little herein, even reach negative pressure, can produce suction to gas channel nearby uses, because there is one section straight hole at the air outlet place of air-inducing passage, the same air-flow that penetrates not only can scattering but also is keep-uped pressure steadily, the air-flow that helps making the air-flow of this burst ejaculation and drive gas channel together rises, second chronotropic action of Here it is two speed change parts.
Main feature of the present invention is: the ingredient of two speed change parts both can be an overall structure, also can adopt and give processing respectively and attach together then and be one, interior its functional effect of realizing of the exhast duct of packing into, it is simple to have processing method, easy for installation, smoke discharging effect good, prevent to pour in down a chimney, the advantage of smoke blowing taint of odour.
