2. Description of the Related Art Conventionally, air purifiers have been used to purify indoor air that has been contaminated by dust, odors, unpleasant gas components, etc. in homes. Conventionally, air purifiers used in homes are generally filter type air purifiers equipped with a dust collection filter that captures dust and an adsorbent / absorbent filter that adsorbs and absorbs odors and gas components such as activated carbon. Met. However, in this case, the purification performance is impaired due to the dust collection filter becoming clogged and the adsorption / adsorbent-containing filter becoming saturated, so cleaning and replacement of the filter is always required, and maintenance is troublesome. It had the drawback of being expensive.

[0003] Another effective method for cleaning dirty indoor air in a house is to replace the clean outdoor air with the dirty indoor air by ventilation. However, in this case, if the outside air is not clean, it may have the opposite effect.For example, if a large amount of pollen is scattered in the atmosphere or the atmosphere is polluted by exhaust gas, soot, odor of dust, etc. Was to worsen the condition of indoor air. However, ventilation of the house was also necessary from the viewpoint of preventing oxygen deficiency and gas poisoning. By the way, in recent years, by exchanging heat between the outdoor air taken indoors and the indoor air exhausted outdoors, a heat exchange ventilation system that reduces indoor heat loss due to ventilation during heating and cooling has been adopted as ventilation equipment for homes. Has been done.

[0004]

In view of the above-mentioned conventional circumstances, there has been a demand for an air purification apparatus capable of satisfactorily and rationally purifying and ventilating indoor air in a house. Considering the entire housing space, conventionally, indoor air purification and ventilation are performed separately for each room unit, and an air conditioning system that can perform ventilation and purification of multiple rooms at once is desired. It was a thing.

Therefore, according to the present invention, a house has a ventilation function for taking in outside air into a room and a cleaning function for purifying outside air and indoor air at the same time, and maintenance for replacing air is not required. The present invention provides a simple air cleaner. Further, the present invention provides a house air conditioning system capable of performing ventilation and cleaning of a plurality of rooms in a house with one device at a time.
