2. Description of the Related Art Conventionally, various devices for drying wet hands after cleaning have been proposed. For example, hot air heated by a heater is blown on the hand to evaporate the water content of the hand and blow it off. Configured devices are known. In this type of hand dryer, the temperature of the hot air is set to a relatively low level because the hot air is directly applied to the hand, and there is a problem that it takes time to dry.

Therefore, recently, a hand drying apparatus has been proposed in which the drying time is shortened by blowing off the moisture of the hand by a high-speed air flow (Japanese Patent Laid-Open No. 6-209879, etc.). According to the hand dryer using this high-speed air flow,
When a wet hand is inserted into the hand insertion part, the high-speed airflow blows the moisture of the hand to the back side of the hand insertion part, and this blown water is drained from the drain port on the back bottom of the hand insertion part through the drain hose. It is designed to drain into a drain tank that is detachably attached to the bottom of the device. When water has accumulated in the drain tank to some extent, remove the drain tank from the bottom of the equipment and drain it.

[0004]

In the above hand dryer using the high-speed air flow, the drain tank is regularly cleaned to drain the water accumulated in the drain tank, and the water overflows from the drain tank. The floor and the like are not flooded, and the user is not discomforted.

However, the drain tank is a flat container with a shallow bottom, and if some water is collected during removal, the water may spill from the drain tank onto the floor surface, etc. As a result, the drain tank could not be replaced quickly, which was troublesome.

In addition, if it is used for a long period of time, water stains may adhere to the inner wall of the drain tank, and mold may be generated.
There is a possibility that it may cause an offensive odor, and that the drain tank may be difficult to clean due to the scale and mold.

Therefore, according to the present invention, the water accumulated when the drain tank is removed does not spill and the scale of water does not adhere to the inner wall of the drain tank.
An object of the present invention is to provide a drain tank for a hand dryer, a method for replacing the drain tank, and a water absorber for the drain tank.

[0008]

In order to achieve the above object, the drain tank of the hand dryer of the present invention is detachably mounted on a hand dryer which is dried by blowing away water from the hand by a high-speed air stream. In the drain tank of the hand dryer for containing the blown water,
A water absorbent body containing a water absorbent resin for absorbing water that has been blown away by the high-speed air flow and has flowed into the drain tank is disposed in the drain tank.

Further, in the method for replacing the drain tank of the hand dryer according to the present invention, the water absorption containing the water absorbent resin for absorbing the water blown into the drain tank by the high-speed air flow and flowing into the drain tank. It is characterized in that the drain tank is removed from the hand dryer when the body is arranged and the water absorber has absorbed a predetermined amount of water, and another drain tank in which a new water absorber is arranged is attached.

Further, the water absorber for the drain tank of the hand dryer of the present invention is constructed by enclosing a water absorbent resin, a powder deodorant, a powder bacteriostatic agent and an antioxidant in a bag made of a non-woven fabric. Is characterized by.

According to the drain tank of the hand dryer of the present invention, the water blown off by the high-speed air flow and drained into the drain tank is absorbed by the water-absorbent resin of the water-absorbing body and accumulated in the drain tank. It does not cause scale, mold, or odor.

Further, according to the method of replacing the drain tank of the hand dryer of the present invention, the water blown off by the high-speed air flow and drained into the drain tank is absorbed by the water-absorbent resin of the water-absorbing body, and the drain water is drained. Since it does not collect in the tank, there is no risk that the water accumulated in the drain tank will spill onto the floor surface etc. when replacing the drain tank. Also, when cleaning the removed drain tank, almost no water accumulates in the drain tank,
There is no risk of water stains or mold adhering to the inner wall of the drain tank, and this can be done simply by discarding the water absorbing body that has absorbed water and rinsing the inside of the drain tank with cleaning water containing detergent.

Further, according to the water absorbent for the drain tank of the hand dryer of the present invention, the water absorbent resin absorbs the water drained in the drain tank, while the bacteriostatic agent causes bacteria to be generated in the drain tank. In addition, the antioxidant suppresses the oxidation of the water drained in the drain tank, suppresses the generation of mold, and the deodorant absorbs the bad odor in the drain tank to deodorize it.
