Description

  The present invention relates to a deodorizing apparatus that adsorbs an odor component having an unpleasant odor, and more particularly, to a deodorizing apparatus with further improved deodorizing performance.

  Conventionally, a deodorizer using activated carbon is placed in a refrigerator to deodorize the refrigerator. In recent years, deodorizers that adsorb odorous components by placing them in entrances, toilets, shoe boxes, and the like have also been provided. However, this type of adsorption deodorizer is simply placed at the entrance, toilet, shoe box, etc., so it does not come into contact with the surrounding air, and only contacts the air in the vicinity of the deodorizer. Therefore, the deodorization speed and applicable space are limited, and there is a problem that it takes a long time to adsorb the odor component.

  In addition, it is assumed that the deodorizing filter is mounted on the indoor unit of the air conditioner because it has antibacterial properties against the deodorization of living odors such as indoor cigarettes and toilets and indoor air pollution by organic substances. 1 can be mentioned.

  In this patent document 1, a deodorizing filter is provided in the air flow path of an indoor unit, and deodorization is performed by adsorbing odor components contained in the air sucked into the indoor unit. However, in this Patent Document 1, odor components can be adsorbed only in a room where an indoor unit is provided, and deodorization can be performed at an entrance, a toilet, a shoe box, a closet or the like where the indoor unit is not installed in a general household. Has the problem of not being able to.

FIG. 9 shows an air purifier 50 of the type installed indoors. A blower outlet 52 is provided at the rear of the upper surface of the main body casing 51, and lower suction ports 53 are provided at the lower part of the main body casing 51. Side suction ports 54 are provided on the side surfaces. Indoor air is sucked into the main body casing 51 from the lower suction port 53 and the side surface suction port 54, and air purified by a streamer discharge unit (described later) provided in the main body casing 51 is blown out from the air outlet 52. The

  FIG. 10 is a diagram showing the flow of air flow in the air purifier 50. Air is sucked from the suction ports 53 and 54 by the fan 56 rotated by the fan motor 55, and the sucked air is prefiltered. 57, purified through the plasma ionization unit 58, the photocatalytic filter 59, and the plasma catalytic filter 60, and blown out from the outlet 52.

The deodorizing cartridge 5 is attached to the cartridge storage portion 62. The deodorizing cartridge 5 is stored and regenerated by streamer discharge.

  Here, in the air cleaner 50, as shown in FIG. 10, the main air flow path F <b> 1 through which the air that has been sucked in is purified and blown out from the air outlet 52 into the room passes, and the vicinity of the air outlet 52. And a bypass air flow path F2 for returning the air to the upstream side. Then, as shown in FIGS. 10 to 12, the cartridge housing portion 62 is disposed in the bypass air flow path F <b> 2, and the bypass air flow is supplied to the deodorizing cartridge 5 housed in the cartridge housing portion 62, so that the deodorizing cartridge 5. The odor component adsorbed on the deodorizer is decomposed and regenerated.

  As a result, when the odor component is adsorbed by the deodorization cartridge 5 (deodorization cartridge 5) at an arbitrary place in the deodorization apparatus 1 and the adsorption performance is deteriorated, the deodorization cartridge 5 is stored in the cartridge housing portion 62 of the air purifier 50. The deodorizing cartridge 5 can be regenerated and the deodorizing cartridge 5 can be regenerated. Therefore, the deodorizing cartridge 5 can be returned to the deodorizing apparatus 1 again to adsorb odor components. Therefore, the deodorizing cartridge 5 can be reused many times, and it is easy to use.

  Further, the deodorizing cartridge 5 of the deodorizing device 1 is a member previously attached to the air purifier 50. By using the accompanying deodorizing cartridge 5 in the deodorizing device 1, the deodorizing cartridge 5 is used. The deodorizing efficiency of the deodorizing cartridge 5 can be increased compared with the case where it is used alone, and the usability of the deodorizing cartridge 5 can be further improved.

  In addition, in the deodorizing cartridge 5 of the deodorizing apparatus 1, in addition to streamer discharge, active species may be generated by an ultraviolet lamp and a photocatalyst, and the deodorizing effect may be regenerated while adsorbing odor components, or plasma discharge. It may be regenerated using active species such as ozone produced by In addition, the regeneration of the deodorizing cartridge 5 may use a regeneration-only machine in addition to using the air purifier 50. As shown in FIG. 13, the streamer discharge unit 60 is disposed on one side of a box body 65 having a lid 64, and a deodorizing cartridge is placed in a floating air passage 66 of active species generated by the discharge unit 60. 5 is arranged to perform reproduction. Furthermore, although the example which uses the activated carbon 12 as an adsorption | suction element was shown, the other deodorizing functional material which can adsorb | suck paper and a odor can also be used. Further, the difference in gas adsorption amount between the air inlet and outlet sides of the deodorizing cartridge 5 in the deodorizing apparatus 1 may be measured, and the adsorption performance of the odor component may be displayed on the display unit 38. Furthermore, a function of removing dust sucked by the fan 4 by a dust collecting filter before suction to the deodorizing cartridge 5 may be provided.
