[0003]

However, the conventional technique has the following problems. First, when the hot air generator is mounted on a ceiling or a high wall surface, the efficiency of heating and drying the bathroom is poor because the warm air is light. In addition, if the wind speed is increased enough to agitate the air sufficiently, a considerable amount of wind will be applied to the wet naked skin, so the heat of evaporation is deprived, and the wind is too strong even if it is cold or cold, so it is comfortable However, there are also problems such as a loud noise. Next, on a wall mounted at a low position, or mounted on a counter or bathtub, high-temperature warm air blows out to places that are easy for people to touch, and hot air blowing parts become hot, making you feel hot, There is even a risk of burns. In addition, the unevenness of temperature and the degree of contact with the wind are large, and it is hard to say that it is comfortable. In any case, the backside of the bathtub, that is, the backside of the bathtub and adjacent to it, which is the most pretentive and causes the propagation of bacteria, mold, and other microorganisms and the accompanying bad odor and odor. It is not possible to dry the floor pan bathtub rest and wall panels. In addition, actual opening 48
In the prefabricated bathroom and drying room described in No. 37939, if the feeding port is provided so as to face the backside space of the bathtub, the backside of the bathtub can be dried. Has a drawback in that the clothes are not efficiently dried because the hot air does not directly hit them. Further, separately from the warm air device, an exhaust port for exhaust air after drying is provided on the ceiling of the bathroom, which leads to an increase in cost. Also, in the bathroom apparatus disclosed in Japanese Patent Application Laid-Open No. 2-128721,
By forced convection or heating by the electric heating unit provided in the bathtub mounting part, around the bathtub mounting part, that is, the back of the bathtub is to be dried, but in the former, only forced convection,
It is apparent that the electric heating section provided in the latter floor pan generally lacks the heating ability, and not only is it not possible to sufficiently dry the backside of the bathtub, but it is not suitable for heating or drying clothes.

The present invention has been made to solve the above-mentioned problems of the prior art, and is effective in heating a bathroom and drying a bathroom and clothes, is safe and comfortable at the time of use, and has a back surface of a bathtub. An object of the present invention is to provide an inexpensive bathroom heating / drying device capable of drying a part.

First, at the time of bathroom heating or bathroom drying, hot air is blown directly into the backside space of the bathtub, so that the backside of the bathtub, which is the most damp, is placed on the backside of the bathtub and the bathtub on the floor pan adjacent thereto. Drains and gratings (drain lids) connected to the back of the bathtub, such as parts and wall panels, can be dried to prevent the propagation of bacteria, mold, and other microorganisms, and the associated odor and odor. I made it.

Next, since the warm air is blown directly into the backside space of the bathtub, from the backside space of the bathtub, the area around the apron of the bathtub (horizontal / bottom) or through the grating (drain lid) from a low position. Since warm air blows out into the bathroom (washing area), heating and drying of the bathroom are efficient, and warm air blows out from the same place, that is, a wide area, indirectly into the bathroom (washing area). It is safe and comfortable to use because it does not become hot enough to cause burns on easy-to-burn parts, and it does not hit the body directly with high temperature or high wind speed, and it can reduce uneven temperature and unevenness of wind contact .

When the clothes are dried, the switching device
Since warm air is blown from the upper horizontal wall surface of the bathtub or the upper surface of the bathtub rim, the warm air is blown directly to the laundry, so that the efficiency of drying clothes can be improved.

Furthermore, the use of multiple members, such as the use of a hot air supply and exhaust for the air outlet and duct and the provision of a ventilation function for the hot air generator, saves space and space. We are trying to save construction and reduce costs.
