Abstract
The utility model relates to an indoor air-conditioning device, particularly an air exchanging fan. The utility model is characterized in that the air exchanging fan is provided with an energy-conducting ventilating pipe which is composed of a conduction pipe and a sleeve pipe, the conduction pipe is arranged in the sleeve pipe, and the energy-conducting ventilating pipe is provided with an electric fan. The utility model can make indoor air positioned at the positive-pressure state and keep sufficient oxygen indoors; in the process of sucking outdoors fresh and pure air and dicharging indoors dirty air, two airflows with temperature difference are carried out with energy conduction and delivery (exchange) through the pipe wall of the conduct pipe during flowing; the air exchanging fan has the advantages of energy recovery, energy saving, etc.
Description
Affiliated technical field
The utility model relates to a kind of indoor air conditioner, specifically a kind of ventilation fan.
Background technology
We know, the effect of ventilation fan is to be discharged into indoor foul atmosphere outdoor, or send into outdoor clean air indoor, present ventilation fan generally is used for being discharged into indoor foul atmosphere outdoor, it generally is provided with the case shell, fan, motor, fan and motor are installed in the case shell, the two ends of case shell are respectively air inlet and air outlet, what have is provided with anti-air grid at the air outlet place, to prevent the wind facies mutual interference of outdoor wind and indoor discharge, influence the air draft effect, in the small gap inlet chamber that outdoor air then exists through between indoor and outdoor, so that indoor energy keeps certain atmospheric density, in the building that cuts off the outdoor air inflow, the unidirectional ventilation fan that turns round can make room air density reduce, thereby causes very dangerous situation.
Therefore, optimal ventilation fan should possess when discharging indoor foul atmosphere, in the fresh air inlet chamber outside the suction chamber, make indoor energy keep certain atmospheric density, to create the environment that adapts to people's life or work most, for this reason, dual direction ventilating fan was proposed once in the industry.
Quanbeiqingyuan Century Co., Ltd. of Korea S in 2000 has applied for Chinese utility model patent for this reason, the patent No. is: 00259083, patent name is: " suction and discharge formula air-filtering ventilation fan ", it is provided with the case shell, be respectively equipped with motor in the case shell, air intake fan and go out fan, case shell upper end (or lower end) is provided with the air-out passage, case shell lower end (or upper end) is provided with air intake passage, because room air and outdoor air have certain temperature difference, as winter indoor since the heating and temperature than outdoor height, summer indoor because cooling and temperature is lower than outdoor, the ventilation fan of this structure is when taking a breath, the air that the temperature difference is bigger is discharged indoor respectively or is sent into indoorly, has caused the waste of energy.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of ventilation fan, and it is when discharging indoor foul atmosphere, in the fresh air inlet chamber outside the suction chamber, make indoor energy keep certain atmospheric density, and the fresh air in the inlet chamber can absorb the airborne energy of discharge.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of ventilation fan is characterized in that being provided with and leads the energy ventilation duct, leads and can be made up of conduit and sleeve pipe by ventilation duct, and conduit is located in the sleeve pipe, leads to be provided with electric fan by ventilation duct.
Other favourable structure of the present utility model forms the object of dependent claims.
In order to guarantee ventilation of the present utility model, lead the energy effect, electric fan is located on the conduit, under the effect of electric fan, outdoor air enters conduit to indoor air-supply, so that air-conditioned room is in satisfactory barotropic state, because room air is under the barotropic state, indoor air can be by the interlayer row who leads the energy ventilation duct to outdoor, room air enters leads the energy ventilation duct in outdoor discharge process, the energy that himself carries (heat or cold) in conduit passes to conduit by outdoor to the indoor air that enters, pass with the reception room of realizing energy, in order more to help indoor discharge air and the outdoor energy exchange that enters between the air, can on conduit, be provided with fin.
The utility model can be provided with electric fan at the interlayer of leading the energy ventilation duct, is beneficial to the exchange of room air and outdoor air, and the utility model can also be provided with air filter on conduit, to purify the air in the inlet chamber.
The beneficial effects of the utility model are: can make indoor air be in barotropic state, make the indoor oxygen that can keep abundance, the air of the fresh cleaning outside suction chamber, give off in the process of indoor foul atmosphere, two strands exist air tube wall by conduit in flowing of the temperature difference to carry out energy transmission (exchange), have the characteristics of energy recovery, conserve energy.
