Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention supplies warm air to a rotating drum to dry clothes, and at least has antibacterial properties.
The present invention relates to a clothes dryer capable of performing antibacterial, antifungal, deodorant, and insect repellent treatment on clothes by volatilizing and diffusing a drug having any one of antifungal, deodorant, and insect repellent properties.

[0002]

2. Description of the Related Art Conventionally, clothes dryers have been constructed in such a manner that clothes which are damp due to washing or the like are dried by putting the clothes in a rotating drum and passing hot air through the clothes while rolling and stirring the clothes. ing.

In recent years, some of such clothes dryers have a sterilizing and acaricidal function. This exhibits a bactericidal and acaricidal effect by moist heat drying by maintaining the clothes at a predetermined temperature or higher during constant rate drying in the drying process.

On the other hand, clothes on which a drug having an antibacterial, antifungal and anti-mite action is adsorbed are commercially available. This antibacterial treated garment is treated with an antibacterial agent before its purchase, and when repeated washing, the antibacterial agent is washed off by its mechanical force, and the antibacterial effect is gradually reduced in many cases.
Hand-washing is displayed as a selection method. Further, in commercially available antibacterial clothing, bleaching is prohibited because the bleach decomposes the antibacterial agent even if stains adhere to it.

Among these, in the antibacterial treated garment utilizing the natural vegetable oil having antibacterial properties, the natural vegetable oil exhibits its antibacterial action when vaporized, so that the natural vegetable oil on the clothes gradually decreases. As is clear from this, it is extremely difficult to maintain the initial performance in the long term. Therefore, it is very expensive, but the antibacterial agent is made into microcapsules, and the microcapsules are gradually broken and vaporized by physical action such as friction when worn.

[0006]

In the conventional clothes dryer having the bactericidal and acaricidal effect, clothes can be dried hygienically, but after the drying is completed, the clothes are stored in a chest of drawers or the like. Contamination of mites and other bacteria during wearing. In other words, even if the product can be dried hygienically, it is a temporary effect that cannot be maintained continuously.

[0007] Further, commercially available antibacterial treated clothes generally have a problem of durability that the antibacterial action gradually decreases after repeated washing. In order to exert the antibacterial property for a long period of time, a large amount of the drug must be adsorbed in the initial stage, and therefore, when the antibacterial treated garment is worn, beneficial skin-resident bacteria may be sterilized. In addition, a highly technical means of microencapsulating natural vegetable oil as a drug is used, resulting in expensive clothing. As a result, antibacterial clothing can be used as MRS in hospitals.
There is a problem that only limited clothes such as hospital clothes for A and pajamas with antibacterial properties imparted with natural antibacterial agents for atopic dermatitis are provided.

[0008] Furthermore, for clothes treated with a natural antibacterial agent for pediatric atopic dermatitis and the like, it is necessary to purchase new antibacterial treated clothes in accordance with the growth of fast-growing children. Although it is possible to directly spray the antibacterial agent with a spray etc. to exert the antibacterial effect, it is necessary to adhere an appropriate amount from the viewpoint of safety and effect, but it is not possible to uniformly adhere the antibacterial agent to the clothes as much as necessary. It's extremely difficult. There is also a risk of inhaling the antibacterial agent or adhering the antibacterial agent to other things.

[0009] In addition, in order to have a comfortable and hygienic clothing life against the backdrop of the weak skin (dry skin) of the aged and the increase of the bedridden aged, and the home for the aged, antibacterial in order to welcome an aging society. Deodorant bedding and bedding are expected.

The present invention solves the above-mentioned problems, and a first object of the present invention is to enable the antibacterial treatment to be performed efficiently after drying the washed clothes.

Further, in addition to achieving the above-mentioned first object, the amount of the dew condensation of the drug volatilized and diffused from the drug supply means on the inner wall of the rotary drum is suppressed to be low, and the drug volatilized and diffused is efficiently attached to the clothes. The second purpose is to do so.

A third object of the present invention is to allow the operation to be terminated with the clothes being dried when antibacterial treatment is not required.
