Abstract
The utility model provides an air discharging device for a house, which has good leak tightness and good thermal insulation effect, and comprises an exhaust fan and an air port housing connected with the air port of the exhaust fan through a flange, wherein, heat-insulating blades are arranged in the air port housing and connected with a process controller which is connected with the exhaust fan; in the air discharging device for the house, the heat-insulating closed electric air port adopting the heat-insulating blades is utilized, so the leakproofness is improved compared with a general louver air port; when a gas extinguishing system is in operation, the electric heat-insulating blade air port is closed, so the indoor positive pressure can be well sustained; and when the fire is quenched, the air discharging is operated and the electric air port and the blower are opened together for air discharging.
Description
Technical field
The utility model relates to a kind of air exhausting device, especially a kind of house air exhausting device.
Background technology
House exhaust method commonly used is in the exterior wall bottom, room that is provided with extinction using gas axial flow blower to be set in the engineering at present, and outdoor section is installed the stormproof louvre air port or the air grille etc. that hangs down certainly.Through finding that the drawback of this type of way is that tightness is poor, heat insulating ability is poor in the reality use.
These shortcomings can make gas extinguishing system condition of a fire when operation occur, need in the room to a certain degree malleation, and the sealing of common blinds is relatively poor, can not effectively keep indoor malleation.When some had the machine room of special cleanliness factor requirement normally to move at ordinary times, outdoor pollutant and winged insect etc. can get into machine room through the insulation blade, are that air does not satisfy the cleanliness factor requirement in the machine room.The area of heating is infiltrated owing to air grille sealing, heat insulating ability difference cause cold wind in the winter time, strengthens the machine room thermic load for no reason, and is not energy-conservation.
The utility model content
The utility model provides the house air exhausting device of a kind of good airproof performance, high insulating effect.
Realize the house air exhausting device of the utility model purpose; Comprise exhaust blower,, be provided with the insulation blade in the said tuyere shell through flange and the tuyere shell that said exhaust blower air port links to each other; Said insulation blade is connected with operation control, and said operation control links to each other with said exhaust blower.
The blade single face of said insulation blade is provided with heat-insulation layer.
The beneficial effect of the house air exhausting device of the utility model is following:
1, adopts the seal of the airtight electric thermal insulating blade of insulation stronger, be in air-tight state during the gas extinguishing system operation, can finely keep indoor malleation than common air grille.After fire extinguished, when air draft started, electric vent and blower fan are chain to be opened, and carries out air draft.
2, the seal of the airtight electric thermal insulating blade of insulation is stronger than common air grille, is in air-tight state at ordinary times, can prevent effectively that outdoor pollutant from getting into.
3, the airtight electronic air grille of insulation be in air-tight state at ordinary times, insulation material is posted in the air port, so its seal and heat insulating ability are stronger than common air grille; Be in air-tight state at ordinary times; Can effectively stop the cold wind invasion, and reduce the heat transfer coefficient of exterior wall, reach energy-conservation purpose.
Description of drawings
Fig. 1 is the structural representation of the utility model house air exhausting device.
The specific embodiment
As shown in Figure 1; The house air exhausting device of the utility model; Comprise exhaust blower 1,, be provided with insulation blade 4 in the said tuyere shell 3 through the tuyere shell 3 that flange 2 links to each other with said exhaust blower 1 air port; Said insulation blade 4 is connected with operation control 5, and said operation control 5 links to each other with said exhaust blower 1.
The blade single face of said insulation blade 4 is provided with heat-insulation layer.
User mode 1: the machine room that extinction using gas is housed is in breaking out of fire, and fire-suppressant gas discharges, and exhaust blower is in closed condition, and airtight insulation electric vent is in air-tight state, well guarantees indoor malleation.
User mode 2: the machine room that extinction using gas is housed is after fire extinguishing, because fire-suppressant gas has toxicity, needs discharging immediately.Open exhaust blower, open in chain air port simultaneously, and blade is 45, is guaranteeing that air draft takes into account rainproof smoothly simultaneously.
User mode 3: the machine room that extinction using gas is housed is at ordinary times during breaking out of fire, and the air port is airtight cuts the outer heat-insulation layer that pastes.Effectively stop outdoor cold air, pollutant or winged insect to get into machine room, keep machine room cleanliness factor and effectively insulation from the air port.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
Claims (2)
1. house air exhausting device; It is characterized in that: comprise exhaust blower,, be provided with the insulation blade in the said tuyere shell through flange and the tuyere shell that said exhaust blower air port links to each other; Said insulation blade is connected with operation control, and said operation control links to each other with said exhaust blower.
2. house according to claim 1 air exhausting device is characterized in that: the blade single face of said insulation blade is provided with heat-insulation layer.
