Description

  The invention of this application relates to a ventilation facility. More specifically, the invention of this application relates to a duct air supply type ventilation facility for distributing and supplying air to each room.

  In recent years, the demand for a healthy and comfortable life due to the improvement of the living environment has increased, and in particular, indoor ventilation and purification of indoor air have been attracting attention as the insulation and sealing performance of residences and the like have improved. Indoor ventilation is performed by introducing fresh outside air, but it is necessary to purify the outside air in an area where the outside air is a problem, and the actual situation depends on the surrounding residential environment. Especially in the vicinity of highways, suspended particulate matter and nitrogen oxides emitted from diesel vehicles, which are the cause of air pollution, have become a problem, and asthma caused by these and the onset of allergies due to pollen, etc. There is a strong demand for the introduction of clean-up of outside air.

  From the viewpoint of introducing outside air purification, the ventilation equipment in a building such as a house has been provided with an outside air inlet (1) and a filter (5) in the space behind the ceiling as illustrated in FIG. The intermediate duct fan (2) is installed, and the duct (3) connected to the air supply port (7) of each room (4) is disposed from the intermediate duct fan (2). The air taken in from the outside air inlet (1) is freed of pollen, nitrogen dioxide, suspended particulate matter, etc. by the filter (5), passed through the duct (3) by the intermediate duct fan (2), and the air inlet ( 7) to each room (4). The air in each room (4) is exhausted to the outside through the vent (13) through the vent (14) communicating with the outside of the room, such as the toilet (15) and the washroom (16). Is done. In this way, in order to create a healthy and comfortable air environment, by creating an air flow throughout the house, generation of mold and ticks is suppressed, and moisture generated from condensation, building materials, furniture, etc. Formaldehyde and volatile organic compounds can be discharged.

  However, in the conventional ventilation equipment illustrated in FIG. 3, the air is purified by removing suspended particulate matter and the like in the air by the filter (5). There was a problem that odor, bacteria, viruses, etc. attached to the inner wall surface of the duct (3) leading to the room could not be removed. Therefore, in order to introduce even cleaner air into each room, it is desirable to clean the inside of the duct, but such a ventilation facility has not been reported yet.

  On the other hand, air purification has attracted particular attention in relation to indoor air pollution, the occurrence of ticks, and the occurrence of allergies caused by pollen from the outdoors. Various types of air purifiers have been developed and put into practical use as means for removing dust and odors. This air purifier has a so-called filter system as a dust collection function and a deodorization function. The dust collection function is sufficiently practical, but the deodorization function exhibits a sufficiently satisfactory performance. There is no current situation. For this reason, when an odorous substance adheres to clothes, walls, furniture, etc., it has been difficult to remove with the above air cleaner.

  Therefore, as a method for solving this problem, an air cleaner (Patent Document 1) provided with electrostatic atomizing means has been developed. Here, the electrostatic atomization means that water is atomized by applying a liquid such as water to a high voltage. And the odor adhering to the indoor wall surface etc. is removed by the charged fine particle water generated by atomization. Furthermore, according to the air cleaner provided with this electrostatic atomizer, bacteria and viruses can be removed.

And since the charged fine particle water generated from the electrostatic atomizer is charged to the same polarity, it is sprayed over a wide range by repulsive force. For this reason, according to the air cleaner provided with this electrostatic atomizer, an odor, a microbe, and a virus are removed over a wide range.
