Abstract

PURPOSE:To perform semipermanent moldproofness, sterilization, and deodorization of the interior of an air conditioner at a low cost, by a method wherein a heater to generate far infrared rays is disposed in the air flow passage of an air conditioner. CONSTITUTION:Spores, germs, odor particles of mold floating in air passing from the suction port of a decorative cover 6 through an air filter 1 are removed through the sterilizing action of far infrared rays by energization of a heater 12 to generate far infrared rays. By means of far infrared rays reflected by a reflection plate 13 and far infrared rays radiated directly from a heater, mold adhered to a heat exchanger 5, a dew tray 2, a blower 4, a casing 3, and a wind direction plate 7 is prevented from breeding. A heater to generated far infrared rays is formed such that a far infrared ray radiation layer 17 may be coated on a general heater having a heat generating wire 14 covered with a filler 15 and a metallic pipe 16, and a semipermanent effect can be provided at a low cost.

Description

[Detailed description of the invention] [Industrial application field] The present invention is used for the interior of air conditioners, especially for mold prevention and sterilization.

The present invention relates to an air conditioner suitable for deodorizing.

[Conventional technology]

As described in Japanese Utility Model Application Publication No. 59-17824 (shown in Figs. 3 and 4), a conventional example is to attach a tape impregnated with a disinfectant to the air filter frame so that the air filter does not get sucked into the vicinity of the filter. This prevents the growth of mold spores, etc.

[Problem to be solved by the invention]

The above conventional technology can prevent the growth of mold on the surface of the filter and the windward surface of the heat exchanger.

No consideration was given to preventing mold on the back side of the heat exchanger, bacteria, and odors in the air flow path after passing through the filter.

The purpose of the present invention is to prevent the growth of mold in an air conditioner, sterilize it, and deodorize the air sucked and discharged.

[Means to solve the problem]

The above object is achieved by disposing a heater that generates far-infrared rays in the air flow path.

[Effect]

By energizing a heater that generates far-infrared rays placed on the leeward side of the heat exchanger in the air flow path, far-infrared rays can prevent the growth of mold spores that have reached the back side of the heat exchanger, as well as sterilize and deodorize them. There is an effect. Also.

The air sucked in through the air suction port, passed through the air conditioner, and discharged becomes m* air due to the same effect.

When the far-infrared M heater is energized during dehumidification operation of the air conditioner, it functions as auxiliary heating during heat pump heating operation, such as heating dehumidification operation.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Figure 1 is a longitudinal sectional view of an air conditioner equipped with a far infrared ray heater, and Figure 2 is a structural diagram showing an example of a heater that generates far infrared rays.

Mold spores, bacteria, odor particles, etc. floating in the air passing through the air filter TFT from the air inlet of the decorative cover 6 of the air conditioner are already known to the public by energizing the heater 12 that generates far-infrared radiation. can be removed by far-infrared-like sterilization. Also.

The far infrared rays reflected by the reflector 131C and the far infrared rays radiated directly from the heater cause the heat exchanger 5. Dew saucer 2.
Blower 4. Casing 3 # Wind direction board 7 attached (can prevent and prevent mold growth. Also).

In the dehumidification operation of electronically controlled air conditioners.

It is known that the room temperature drops, but by energizing the heater 12, l) comfortable dehumidifying operation with a slight heating effect can be performed. During warm N operation, the heater 12 can work auxiliaryly. Figure 2 shows an example of a heater that generates a far-infrared layer, but it is a general example in which the heating wire 14 is covered with a filler 15 and a metal pipe 16. It is sufficient to coat the heater with the far-infrared emitting layer 17, and the performance is obtained at low cost and the effect is semi-permanent.

[Effect of appearance]

According to the present invention, by arranging a heater that generates far infrared rays in the air flow path of an air conditioner, mold prevention, sterilization, and deodorization within one machine can be performed semi-permanently and at low cost.

In addition, the heater allows dehumidifying operation with a slight heating effect.
