Abstract
The utility model discloses a pressure changing non-return air exhaust device which is installed in an air exhaust channel and is composed of a main partition plate and a change inducing box. The main partition plate is a rectangular plate, the upper part of which is provided with a hole, the change inducing box is a semi-closed box body, the lower bottom surface of which is an inclined plane, and the change inducing box is installed on one side of the hole. An inclined partition plate is arranged at the lower end of the main partition plate and on the opposite side of the change inducing box, and a butterfly wing-shaped air shielding plate dragged by a spring is fixed at the upper end of the change inducing box through a hinge. The utility model thoroughly eliminates the phenomena of fume crossing, smell crossing, and upwind back flow of original fume channels and can improve the fume exhausting efficiency of existing air channels.
Description
The utility model relates to a kind of transformation non-return air exhausting device.
For solving the kitchen fume problem, in building construction, all to design air exhaust channel.At present, the air exhaust channel that building or one-storey house adopted mainly is main formula air exhaust channel and brick air exhaust channel, promptly build near the position in kitchen airtight cylindrical channel is arranged at dwelling house, and leave hole at the place, kitchen and range hood usefulness is installed for family, this air channel exists shortcomings such as smoke blowing taint of odour, exhaust air rate is little, resistance is big, especially can be subjected to the influence of weather at the exhaust outlet place, have the top layer strong wind to pour in down a chimney into the defect in the inlet chamber in the air channel.
The purpose of this utility model is exactly the shortcoming that solves existing dwelling house air exhaust channel, and a kind of transformation non-return air exhausting device is provided.
The purpose of this utility model is achieved in that transformation non-return air exhausting device is installed just can overcome above-mentioned shortcoming on the air exhaust channel of existing dwelling house, transformation non-return air exhausting device by main dividing plate, lead and become box and form, main dividing plate is the rectangular plate that top has the hole, leading the change box is the semiclosed box body on inclined-plane into bottom surface, lead and become the side that box is installed in the hole, lead the offside that becomes box in the lower end of main dividing plate and be provided with an inclined clapboard, it and main dividing plate are 45.Also be fixed with butterfly wing shape barge board by hinge leading the upper end that becomes box by spring or tension piece tractive.
The phenomenon that this device has thoroughly been eliminated chimney smoke leakage taint of odour in the past, poured in down a chimney against the wind behind this device of installation, can improve smoke exhaust efficiency greatly in existing air channel, simplify construction sequence, guarantees the quality in air channel.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1: transformation non-return air exhausting device structural representation;
Fig. 2: transformation non-return air exhausting device scheme of installation;
Among the figure: 1-inclined clapboard, 2-main dividing plate, 3-lead become box, 4-barge board,
5-spring or tension piece, 6-hole;
Transformation non-return air exhausting device by main dividing plate 2, lead and become box 3 and form, as shown in Figure 1, main dividing plate 2 has the rectangular plate in hole 6 for top, leading change box 3 is the semiclosed box body on inclined-plane into bottom surface, lead and become the side that box 3 is installed in hole 6, it has the guiding elbow and changes the double action of flue area, and regulates the dynamic pressure and the static pressure of air-flow by changing the flue area.If one-storey house or at the top layer of building, also be fixed with butterfly wing shape barge board 4 by hinge leading the upper end that becomes box 3 by spring or tension piece 5 tractives, when proper functioning, the angle of barge board 4 is very little, help smoke evacuation, do the time spent when external blast is arranged at the top, will force barge board 4 to open, blast is big more, the degree that barge board 4 is opened is big more, it is a force balance, regulates the dynamic component in pressure, change cross section that it has guaranteed that interior wind effluxes, and has solved the phenomenon of irritating in the exogenous wind effectively; Lead the offside that becomes box 3 in the lower end of main dividing plate 2 and be provided with an inclined clapboard 1, it and main dividing plate 2 are 45.
During use transformation non-return air exhausting device is placed in the existing rectangle air exhaust channel, as shown in Figure 2, main dividing plate 2 is separated into main, two air channels with air channel, only hole, the position of inclined clapboard 1 is below the kitchen exhaust mouth, it carries out the majority separation with branch air duct, guaranteed not collaborate in the branch air duct, mixed cigarette, and oil gas is behind the long branch flue of process, oil gas separates, prevents that greasy dirt from entering main flue channel.After this device is installed, can improve smoke exhaust efficiency greatly in existing air channel, simplify construction sequence, guarantee the quality in air channel.
Claims (2)
1, a kind of transformation non-return air exhausting device by main dividing plate (2), lead and become box (3) and form, it is characterized in that: main dividing plate (2) has the rectangular plate of hole (6) for top, leading change box (3) is the semiclosed box body on inclined-plane into bottom surface, lead the side that change box (3) is installed in hole (6), lead the offside that becomes box (3) in the lower end of main dividing plate (2) and be provided with an inclined clapboard (1).
