Abstract
The utility model relates to a wind-powered ventilating hood, which comprises a ventilating pipe, a gas collecting hood and a flow dividing hood. The horn-shaped gas collecting hood and the conical flow dividing hood are orderly sheathed on the end part of the ventilating pipe. Wind flow is gathered at the position of an annular slot which is formed by the gas collecting hood and the flow dividing hood. The flow-rate is quickened, and a low-pressure region is formed. Indoor gas is sucked out to the open air through the ventilating pipe by a ventilating hole which is arranged on the flow dividing hood. The utility model has the advantages of simple structure, low cost, no energy consumption, low noise, high safety and long service life. The utility model can be widely used for sucking gas and ventilating in a room in the area where wind energy is abundant. The utility model can also be installed on the top of a chimney of a stove, so as to play the functions of circulating air and supporting combustion.
Description
The utility model belongs to air interchanger, is specifically related to a kind of range hood that utilizes the wind-force ventilation or bleed.
For air cleaning in the holding chamber, to reduce and pollute, some places of bleeding, taking a breath at needs at present all are equipped with air interchanger.Resident family adopts smoke exhaust, ventilation fan and air conditioner mostly, and the factory building of factory often adopts air exhauster, overhead chimney etc.What have in these methods needs power supply, the cost height that has, and what have has noise or the like.
The purpose of this utility model provides a kind of power supply that do not need, the range hood that only utilizes wind-force just can take a breath or bleed.
Technical solution of the present utility model is: the wind-force range hood is made up of breather pipe, gas skirt, fluid dividing cover three parts, the gas skirt of profile flare and taper fluid dividing cover are sleeved on the end of breather pipe successively, and connect by fixed block: gas skirt and fluid dividing cover suit partly leave the annular gap of air intake, fluid dividing cover and breather pipe suit partly leave the annular gap of exhaust, and fluid dividing cover is provided with passage.
According to design of the present utility model, the also salable breather pipe end that is connected of taper fluid dividing cover, the passage on the fluid dividing cover passes breather pipe, direct and breather pipe internal communication.
The utility model mainly adopts bernoulli principle to realize the purpose of bleeding, suppose that wind promptly axially blows to range hood from the front, in annulus distinguished and admirable the gathering of place of gas skirt and fluid dividing cover, flow velocity is accelerated, inevitable at this place, slit formation low-pressure area, thus by the passage that is provided with on the fluid dividing cover that indoor gas is outdoor by the breather pipe sucking-off.
If wind promptly radially blows to range hood from the side, distinguished and admirable equally can be at the annular space formation low-pressure area of gas skirt and fluid dividing cover, thereby the sucking-off indoor gas reaches the purpose of ventilation.
Further describe the utility model below in conjunction with accompanying drawing:
Accompanying drawing is a wind-force range hood structural representation.
Wherein: 1, breather pipe 2, fluid dividing cover 3, gas skirt 4, fixed block 5, passage
As shown in the figure, the wind-force range hood is made up of breather pipe 1, fluid dividing cover 2, gas skirt 3 three parts, and breather pipe 1 is a straight tube shape, and fluid dividing cover 2 profiles are tapered, gas skirt 3 profile flares.During installation, breather pipe is communicated with indoor, and gas skirt and distinguished and admirable cover are sleeved on the end of breather pipe successively, and connects by fixed block 4.Gas skirt 3 partly is a straight tube shape with fluid dividing cover 2 suits, and suit partly leaves the annular gap of air intake, and fluid dividing cover 2 and breather pipe 1 suit partly leave the annular gap of exhaust, and fluid dividing cover is provided with passage 5.
The utility model is simple in structure, cheap, Non-energy-consumption, and noise is little, and is safe and reliable, the longevity Life is long. Can be widely used in indoor the bleeding, take a breath in the more rich area of wind energy, also can be installed on cooking stove Ventilating air, combustion-supporting effect are played in the chimney top.
Claims (2)
1, a kind of wind-force range hood is characterized in that being made up of breather pipe, gas skirt, fluid dividing cover three parts, and the gas skirt of profile flare and taper fluid dividing cover are sleeved on the end of breather pipe successively, and connect by fixed block; Gas skirt and fluid dividing cover suit partly leave the annular gap of air intake, and fluid dividing cover and breather pipe suit partly leave the annular gap of exhaust, and fluid dividing cover is provided with passage.
2, wind-force range hood according to claim 1 is characterized in that the also salable breather pipe end that is connected of taper fluid dividing cover, and the passage on the fluid dividing cover passes breather pipe, direct and breather pipe internal communication.
