BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a preferred embodiment of an air purifying apparatus according to the present invention will be described. The present invention relates to the installation of an electronic unit provided in an air purifying apparatus and the wiring process associated therewith, and there is no limitation on the dust collection method of the air purifying apparatus itself as long as the above-described present invention can be realized.
Typically, the fan system is provided with a dust collecting filter unit composed of a HEPA filter or the like, but is not limited to this system. A so-called electric precipitating system, an ion system (fanless system) or a photocatalytic system may be used. In addition, the present invention can be suitably embodied in a high-performance air cleaning device that combines these dust collection methods.

Alternatively, the air purifying apparatus of the present invention does not need to be an air purifying apparatus having only an air purifying mechanism (such as a general household air purifier). It may be a type air cleaning device. As a good example of such a multifunctional air purifying device, a device provided with a regenerative system such as generally referred to as an air purifying fan heater, a warm air system or another heating mechanism, or a general heat exchange system or the like is provided with a cooling mechanism. A device (for example, an air conditioner equipped with an air purifying function equipped with a HEPA filter) is also included in the air purifying apparatus of the present invention as long as the present invention can be realized.

In configuring the air purifying apparatus of the present invention, there is no particular limitation on a portion where the above-mentioned electronic unit collective mounting portion is provided, as long as a space for installing two or three or more electronic units close to each other can be secured.

Alternatively, in a case where a space for providing the electronic unit collective mounting portion inside the housing cannot be ensured, the electronic unit collective mounting portion may be independently provided outside the housing. In this case, it is required to provide a cover member around the periphery to shield the electronic unit collective mounting portion from the outside.
The electronic unit collective mounting portion may be formed by molding a part of a housing or a fan casing itself into a shape in which a plurality of electronic units are directly installed. An electronic unit collective mounting portion formed in a shape for mounting a unit mounting board is particularly preferable. According to the electronic unit collective mounting portion having such a detachable electronic unit mounting board, it is possible to flexibly cope with a change in the shape of an electronic unit to be mounted or additional mounting. That is, when the shape of the electronic unit to be mounted is changed or another new electronic unit is mounted, a new electronic unit mounting board corresponding to the change is mounted on the main body of the apparatus. It is possible to easily deal with such a change in the shape of the electronic unit and a change in the system of the electrical system without changing the shape of the electronic unit collective mounting portion itself.

On the other hand, two or three or more electronic units mounted on the electronic unit collective mounting portion or the electronic unit mounting board are involved in control for operating the air cleaning apparatus of the present invention under predetermined conditions in some form. There is no particular limitation as long as it is an independent electronic unit (electrical component). However, when an air cleaning process or another process (heating operation, humidification operation, etc.) is performed, a function having a mutually related function regarding control of the process is performed. Alternatively, it is particularly preferable that three or more electronic units (hereinafter referred to as “interrelated electronic unit group”) are mounted so as to be arranged close to each other. Preferable examples of such an interrelated electronic unit group include a control unit for controlling the air purification processing capacity (for example, adjusting the rotation speed of a fan motor) and one or two types of so-called dirt sensors for detecting dirt in the air. Combinations with the dirt sensor unit described above can be given. Alternatively, when the air purifying apparatus embodying the present invention is a gas fan heater with an air purifier having both an air purifying mechanism and a gas warm air heating mechanism,
It is selected from a control unit for adjusting the air cleaning treatment capacity, the above-mentioned dirt sensor unit, a control unit for controlling the gas hot air heating operation ability (for example, adjusting the thermal power of the gas burner), and a temperature sensor unit for detecting the room temperature. Combinations of two or more electronic units are also suitable as a group of interrelated electronic units.
