Secondly, there is a method of replacing existing equipment with an air purifying function, such as an outside air intake device such as a ventilation fan and an indoor air circulation device such as an air conditioner. Thirdly, there is a method in which an opening for ventilation is added to the outer wall of the building, and an electric air cleaner is attached to the opening.

[0003]

Some sash windows, sash doors and the like have ventilation holes in the frame portions, and these are provided only with a net material that prevents insects from entering. Therefore, invasion of pollen, dust and the like cannot be prevented. Therefore, as long as this vent is open,
Even if the third method is applied, those effects are reduced by half, and even with the first measure, that is, the method of installing an air purifier in the room, pollen and dust entering the room are cleaned with air. May cause harm to the human body before being removed by suction.

Further, pollen and dust, which have once entered the room, adhere to curtains or accumulate on the back side of furniture, etc., so that they are again fluttered by the airflow generated in the room and cause secondary damage. It also leads to bringing. In the above-described second and third methods, the facility cost is high and a large-scale construction is required, so that there is a case where the feasibility is low. In addition, the appearance inside and outside the building may be degraded, leading to a feeling of oppression.

The present invention has been made in view of the above circumstances, and it is possible to reliably clean the air flowing into a building, and at the same time, the construction and the like can be performed inexpensively and easily. It is an object of the present invention to provide an air purifier that does not deteriorate the air quality.

That is, in the air purifying apparatus according to the present invention, for example, a case in which a filter is provided for various natural ventilation openings provided in a building, such as a sash window or a ventilation port provided in a frame portion of a sash door, is provided. It is configured to be attached.

[0007] Therefore, when outside air containing pollen, dust, and the like attempts to flow into the building through the natural ventilation opening, the pollen, dust, and the like are removed by the filter, and clean air enters the building. Only will be passed. With such a configuration, since no electric part is provided, there is an advantage that the structure of the entire apparatus is small, simple, and inexpensive, and construction and the like can be easily performed.

[0008] In addition, in this manner, an air purifying device, which is converted into a household electric appliance, is installed in the room, and existing facilities such as an outside air intake device such as a ventilation fan and an indoor air circulating device such as an air conditioner are air-purifying functions. If it is replaced with the one with the attached, pollen, dust and the like can be almost completely removed in the building.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment of an air cleaning device 1 according to the present invention. The air purifying apparatus 1 is configured by attaching a case 6 containing a filter 5 to a natural ventilation opening 2 provided in a building.
