Abstract

The utility model relates to a unidirectional scavenging window for a building, which can avoid mutual gas blowby between floors. A movable door 2 and a door frame 1 are arranged on a wall passage which is communicated with gas passages and each living room in the building. A door handle is arranged on the movable door, the shape of the door handle is similar to a table tennis racket, the movable door is hinged with the door frame through the door handle, simultaneously the end of the door handle is provided with apendulum 3, and the swing groove 6 of the pendulum 3 is arranged on the door frame 1. In the family provided with an exhausting fume kitchen range, fume flow with power can blow a swing angle towards the movable door 2. The fume enters the gas passage and is exhausted to the outer part of the building, the exhausting fume kitchen range stops working, the movable door restores the prime position under the action of the pendulum, and the mutual gas blowby of each floor resident is avoided.

Description

The unidirectional air hole of building

The utility model relates to the transom window that can realize unidirectional ventilation between every layer of resident family of a kind of building and airway.

Kitchen, washroom are equipped with the louvered transom window by the natural ventilation design in every layer of resident family of building, can discharge indoor flue gas and foul smell by airway.At present, on the family wear that has smoke exhaust range, borrow transom window and airway to make flue, because the about ventilation of louvered transom window; Each layer flue gas usually has scurries logical phenomenon mutually, and the lower floor position occupies the chamber toward the upper strata scurries, and when cooking as lower floor, its smell is all scurried into upper strata, contaminated environment, is unfavorable for physical and mental health.

It is not enough in the above-mentioned prior art that the purpose of this utility model is to avoid, and provide a kind of building interlayer not scurry logical unidirectional air hole mutually.

The purpose of this utility model can reach by the following technical programs: on airway in the building and wall duct that each layer resident family is communicated with valve and doorframe are housed, door handle is arranged on the valve, hinged by door handle and doorframe, the door handle end is equipped with pendulum simultaneously, and the groove of pendulum swing is arranged on the doorframe.Above-mentioned valve and door handle shape such as table tennis bat can rotate around swivel pin, form free pendulum mass and can realize its purpose.

The utility model can have following effect than above-mentioned prior art: this transom window is made of valve and doorframe, is closed condition under the normality, and the inside and outside does not have gas-blowing phenomenon; When smoke exhaust range is worked, under the effect of power flow of flue gas, can make valve swing an angle, open airway.Flue gas can be got rid of; Smoke exhaust range quits work, and valve recovers former sealing state under the action of gravity of pendulum, is applicable to the transom window of dress smoke exhaust range, has prevented the phenomenon of the mutual gas blowby of floor gap.

Fig. 1 is the utility model sectional drawing;

Fig. 2 is Fig. 1 vertical view.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

The corridor both sides are provided with by the airway of first floor to top floor, are communicated with each layer resident family by the wall duct, and this duct is also as the smoke vent that smoke exhaust range is housed.Shown in Fig. 1,2, valve 2 and doorframe 1 are housed on the above-mentioned duct, with the bonding doorframe 1 of sand mud, can be square or rectangle, the shutoff duct valve 2 arranged.Valve directly is slightly smaller than the footpath, duct, makes the two for movingly; Door handle 5 is arranged on the valve 2, and shape such as table tennis bat are hinged by door handle 5 with doorframe 1; Can on the doorframe of hinged place, be shaped in advance and sit ear 7, make jointed shaft, can make the valve free deflection with bearing pin 4.For the valve after making partially can set back, pendulum (weight) hammer 3 is equipped with in the end of doorframe 5, and the space (groove) 6 of pendulum swing is arranged on the doorframe.Handle live during installation down, and around bearing pin 4 swings the time, shape such as human body one leg ride on the horizontal bar, valve shape such as upper body, and door handle such as other one leg, pendulum affects up and down mutually as a pin on this leg.

Can form angle between above-mentioned door handle 5 and the valve 2, wherein handle is following in the above for valve, and the center line of the two (2,5) can help the effect of pendulum on a vertical guide.
