In the case of the air cleaner having the above-mentioned structure, the adsorption type deodorizing filter is generally made of activated carbon, zeolite or the like. Since the odorous components are adsorbed in the pores, the deodorizing performance is greatly reduced due to the surface pores of the deodorizing material being blocked by the odor adsorption.In addition, there are catalytic deodorizing methods and odor decomposition methods using ozone. also for the treatment air volume even household air cleaner is 1 m ³ / min ~4m ³ / min, the catalyst system ozone scheme both fairly large-scale apparatus is required, there is a disadvantage that the cost is too high It was

[0008]

The air purifier of the present invention eliminates the above-mentioned drawbacks, and is an air purifier equipped with an adsorption type deodorizing filter such as activated carbon or zeolite which is general and inexpensive during normal operation. In order to initialize the deodorizing performance, a closed circulation path centered on the filter is constructed in the fuselage, and a circulation fan, air heating section, and odor decomposition means are provided in the circulation path. It was done.

[0009]

With the above structure, the performance of the deodorizing filter can be maintained for a long time with a small-scale device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the air cleaner of the present invention will be described below with reference to FIGS.

In FIGS. 1 and 2, the main body case 10 is constructed by forming a housing with resin or the like, and an exhaust port 11 for exhausting the air in the main body case 10 is provided on the upper part of the main body case 10. Has been. Also, the main body case 1
In front of 0 is a suction port that consists of a grill that sucks in air 1
Two are provided.

A fan motor 13 is fixed and supported by a support member 14 inside the main body case 10. The blower fan 15 is fixed to the rotating shaft 13a of the fan motor 13, and the air sucked from the suction port 12 by the rotation of the blower fan 15 is sent to the discharge port 11. There is an inner case 16 made of a metal plate or the like, which is interposed between the suction port 12 and the air blown by the fan motor 13 and the blower fan 15.

A plurality of holes 16 are formed in the front and rear surfaces of the inner case 16.
There is a, and on the back side of the front and rear surfaces of the inner case 16, there is provided a slide plate 18 which is held by a rail metal fitting 17 and moves left and right. The slide plate 18 has a plurality of holes 16a in the inner case 16.
There is a plurality of holes 18a in the same arrangement as the slide plate 18
When the slide plate 18 is moved to the left, the holes 16a of the inner case 16 and the holes 18a of the slide plate 18 overlap each other. When the slide plate 18 is moved to the right, the holes of the slide plate 18 do not have holes. It acts so as to block 16a.

A connecting fitting 19 of the slide plate 18 partially protrudes from the inner case 16, and a solenoid 20 connected to the connecting fitting 19 can move the slide plate 18 to the left and right. The filter case 20a can be inserted almost in the center of the inner case 16,
A dust collecting (dust removing) filter 21 and a deodorizing filter 22 are housed in 0a. The inner case 16 has a front space 23 and a rear space 24 with the filter case 20 as a boundary. Back space 2
4 is provided with a suction port, and the ventilation unit 2 for circulation of this suction port
There is a circulation motor 26 that connects 5 and drives the circulation blower. A duct 27 is connected to the air blowing side of the circulation air blower 25, and the duct 27 is connected to the front space 23 of the inner case 16. In the duct 27, an ozone generator 28,
An ozone decomposition filter 29 and an air heater 30 are arranged.

With the above construction, during normal operation of the air cleaner, the fan motor 13 is energized to rotate the blower fan 15, and at the same time the solenoid 20 causes the slide plate 18 to move to the left side so that the plural holes 16a of the inner case 16 are formed. Make it open. As a result, the air entering through the inlet 12 of the main body case 10 passes through the dust collecting filter 21 and the deodorizing filter 22 in the inner case 16, the dust particle odor is removed, and the air is blown to the blower fan 15. Through outlet 11
Released more. The deodorizing filter 22 used here is of an adsorption type such as activated carbon or zeolite.

Next, the performance initializing operation of the deodorizing filter 22 will be described in the process in which the surface adsorption holes of the deodorizing filter are closed by the normal cleaning operation and the performance is deteriorated.

When the odor adsorption progresses, the deodorizing filter 22 is left in the atmosphere to re-emit the adsorbed odor. It is known that reheating is activated by further heating. Therefore, when the performance of the deodorizing filter deteriorates,
When the initialization operation is performed by programmed automatic operation or manual operation, the slide plate 18 is moved by the solenoid 20.
Moves to the right and the plural holes 16a of the inner case 16 are closed. Next, the circulation motor 26, the ozone generator 28, and the air heating motor 30 are energized. The blower 25 for circulation is driven by the energization of the circulation motor 26, the air in the rear space 24 is sucked in, the ozone generator 28 part, the ozone decomposition filter 2
9. The air heater 30 is passed through the duct 27 to be sent to the front space 23. Further filters 21,2
Circulation takes place in a closed cycle through 2 to the rear space 24.

During this circulation process, the warm air (about 80 ° C.) emitted from the air heater 30 heats the filters 21 and 22 to re-emit the adsorbed odor. The re-emitted odor is sucked into the circulation air blower 25 from the rear space 24, decomposed into odor by the ozone generator 28, and excess ozone is removed by the ozone decomposition filter. Deodorization filter 22 in cycle of odor re-emission by heating → odor decomposition by ozone → ozone removal
Will be refreshed. At this time, the main blower motor 13 is not driven.
