BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a bath and a clothes dryer, and a bath and a sauna while maintaining the function of the bath.

[0002]

2. Description of the Related Art 1). In a conventional clothes dryer, clothes are put into a rotating drum and dried with warm air, or by blowing warm air from the ceiling of a bathroom to dry. Therefore, it is independent of the bathtub. 2). In the conventional sauna, a method of forming a sauna room in a box shape and heating it by electric heat is adopted. Therefore, it is independent of the bathtub.

[0003]

[Problems to be Solved by the Invention] 1). Conventional clothes dryers and saunas are installed independently of each other regardless of the bathtub. In view of this, the present invention has a function of the bath as it is, and the hot air from the hot air generator is spread on the bottom of the bath.
It sends it to the blowing mat and the snowboard, and blows warm air from here to heat clothes and the human body in the flow. Therefore, warm air blowing
Just put away the mat and the drainboard, then the bath water
The heating efficiency is good due to the chimney effect of the bath . 2). In the conventional box-type sauna, the temperature difference between the upper and lower sides of the box is large, and the air temperature is high at the top and low at the bottom. For this,
The face is hot, but the legs are cold. In view of this, according to the present invention, a person can relax in the bathtub by relaxing the legs, and warm air is constantly blown up from the bottom of the bathtub and circulates. The face is outside. Therefore, each part of the body is heated uniformly with no temperature difference, and is the negative pressure in the upper part of the tank due to the warm air circulation?
It is said that the outside air, which is cooler than the surroundings of the face, flows in and is refreshing.
The heating efficiency is also very good.

[0004]

[Means for Solving the Problems] 1). Warm air blowing that retains the function of the bath and spreads warm air from the hot air generator on the bottom of the bath
Out by blow warm air from此feeding the mat to form a drying chamber by and tub and tub top space. 2). Keep the bath function and bathe warm air from the hot air generator
And blown warm air from此sent to a warm air blowing slatted expanded to the vessel bottom, the sauna room is formed by the tub and the bath cover, and by circulating warm air.

[0005]

[Operation] 1). The function as a bath or bath is the same as before. 2). The hot air generator is hung on the wall surface in contact with the bathtub, and the hot air is blown evenly from the mat placed on the bottom of the bathtub and exhausted from the ventilation fan or ventilation hole at the top of the bathtub. Thus, a stream of rising warm air is created and clothes are suspended in it. Bathtub for this
And 100% of the upper space can be used to dry many clothes
The heating efficiency is good due to the stack effect of the bathtub . 3). A warm air generator is hung on the wall surface in contact with the bathtub, and hot air is blown up evenly from the slatto placed on the bottom of the bathtub to form a sauna room, and a person lays in it to make a sauna. The warm air blown up enters the recirculation duct from the duct insertion port provided in the middle of the lid and returns to the warm air generator. Thus, the upper part of the tank becomes a negative pressure and the cold outside air keeps on your face.
It's relatively comfortable and the heating efficiency is very good . 4). The inner wall of the bathtub is kept at about 40 ° C for clothes drying and 50 ° -70 ° C for sauna. Therefore, a large amount of long-wave infrared rays (far infrared rays) is radiated from the wall surface, which is absorbed by clothes and the human body and is combined with warm air to enhance the heating effect. 5). The hot air generator is located on the floor of the washroom, outside the bathroom, or in the ceiling of the bathroom.
You may install it on the back .

Effect of the Invention INDUSTRIAL APPLICABILITY The present invention can exhibit many new functions such as clothes drying and a sauna by retaining the bath function and adding a few parts as additional options. Therefore, it is very effective and convenient in a place such as an apartment where there is not enough space. Further, since the structure is simple and the number of parts is small, this can be provided at low cost. 2. When you use a bathtub to dry clothes and perform a sauna in the bathroom, the inner surface of the bathtub is heated by warm air, causing a large amount of infrared rays (far infrared rays) with a long wavelength to be emitted from the bathtub surface. It is absorbed by clothing and the human body, increasing the heating effect together with warm air. Warm air temperature is 40 ° C for clothes drying
Position, and therefore the peak wavelength of infrared radiation emitted from the bath surface (wavelength that emits the most infrared rays at that temperature)
Is 9.3 μm, while in the case of a sauna the warm air temperature is 50
It is about 70 ° C to 70 ° C. Therefore, if the average temperature is 60 ° C., the peak wavelength is 8.7 μm. As shown in FIG. 13, when a bath made of FRP is used, as shown in FIG.
The relationship between the infrared emissivity (emissivity) of R and P and the wavelength is shown. In the figure, the infrared emissivity of FRP is about 67% when the peak wavelength is 9.3 μm (clothes dry), and about 73% when the peak wavelength is 8.7 μm (sauna). Therefore, in this temperature range, F / R / P emits a large amount of infrared rays. Even if the bathtub is made of wood such as cypress, the infrared emissivity of wood in that temperature range is as high as about 80%, and a large amount of infrared rays can be emitted regardless of which bathtub is used, and an infrared heating effect can be expected. High drying efficiency can be obtained by the synergistic effect of warm air in clothes drying and sauna. 3. In a commercially available clothes dryer, clothes are put in a rotating drum and dried with warm air. Further, a clothes dryer having a structure in which hot air generated from a heat exchanger for hot water installed in the ceiling of a bathroom is blown downward from the ceiling and at the same time exhausted by an adjacent ventilation hole or fan is also commercially available. In this case, hot water from a water heater installed in the house or outside of the house is supplied to the heat exchanger by piping. Compared with these commercially available clothes dryers, the clothes dryer of the present invention has the following major features. 1). Compared with warm air drying by putting clothes in a rotating drum, (1). Since I put clothes in the drum, only small clothes such as underwear can be dried. Also, the amount per serving is small.
On the other hand, the present invention can hang and dry large items such as clothes, kimonos, towels, and blankets. (2). Commercial dryers only dry with warm air,
In the present invention, due to the synergistic effect of warm air and infrared rays, the drying efficiency is high and the drying time is short. (3). Midnight power can be utilized in the clothes dryer of the present invention. If you wash it at night and set the dryer in it, the drying will finish the next morning. Therefore, it is especially convenient for double-income households and can be dried at low cost. (4). While commercial drum rotating clothes dryers are expensive, the clothes dryer of the present invention is only a bath option and is very inexpensive. 2). Next, a comparison is made with a hot water dryer installed in the ceiling of the bathroom. (1). FIG. 14 shows a dryer installed behind the ceiling.
In the figure, (53) hot water is supplied (returned) to a heat exchanger (57) through a pipe (54) from a water heater installed inside or outside the house. (55) The fan sucks the air in the upper part of the bathroom through the (56) suction port, part of which is discharged into the room through the (58) exhaust port, and part of it is outdoors by the (60) fan through the (61) exhaust port. Is discharged to. Thus, some air in the bathroom (59) creates a stream of warm air and circulates. In this case, hang (9) on (8) mounted near the ceiling of the bathroom to dry. This drying method has the following major drawbacks. I. Because cold air has the property of being down and warm air rising, this method causes the reverse chimney of the air flow. For this reason, (59) does not reach the lower part, but returns to the upper part of the bathroom. B. Therefore, as shown in the figure, the long clothes do not dry easily at the bottom, and the drying efficiency is extremely poor. C. Further, since the clothes are hung on the upper part close to the ceiling, the hanger is too expensive to attach and detach the clothes, and the workability is very poor. D. Due to poor drying efficiency, it is necessary to increase the heat capacity of the heat exchanger more than necessary. In the case of the present invention, 770-1,
030Kcal / hr, 0.9-1.2K in electric capacity
w. On the other hand, the dryer installed above the ceiling is 280
It is 0 to 3,500 Kcal / hr and 3.3 to 4.1 Kw in terms of electric capacity. Therefore, it is uneconomical. E. The dryer installed on the ceiling is complicated in structure and very expensive as compared with the present invention. Also, a water heater and indoor piping are required. F. It can be installed only when a house is newly built or modified, and adjustment and maintenance are complicated. (2). As shown above, the clothes dryer of the present invention is superior in all respects to the dryer installed on the ceiling. 3). Next, referring to FIG. 15, a commercially available drying system shown in FIG.
When the system of the present invention is installed in the bathroom under the same conditions as
Indicates. In the figure, (62) the outside air from the intake hole is
It is heated in (3) and becomes hot air.
Pass through 2) and (5), enter (6) and blow up from (10).
ing. In this case, blow up uniformly over the entire surface of the bathtub.
The bathtub acts as a chimney, and the warm air
It becomes the flow of (63) and is sucked into (11) of the ceiling. Or
The bathtub and its upper part have a chimney effect,
Is hung. The chimney effect is the atmospheric density of Pa.
(Kg / m ³ ), Pb is blown and the density of warm air (kg / m ^3
3 ), if the effective height is H (m), ventilation as a chimney
The force (ΔP) is ΔP = H (Pa−Pb) kg / m ² .
A hot air flow is generated in the bathroom. Due to this effect, (1). Even if a lot of clothes are hung, it can be dried efficiently.
it can. For example, even in a small bathtub of 3/4 tsubo, 1 Kw of electricity
It is possible to completely dry 7 kg of clothes by force in 4 hours.
it can. The thermal efficiency of drying in this case reaches about 38%
It This is similar to a commercial rotary dryer
It (2). Warm air is blowing out from the bottom of the bathtub, so clothes
Can be hung low as shown. Therefore, in women
Is very easy to handle. Insert the hanger into the metal fitting on the wall.
It is crowded. Therefore, when not in use, it should be removed.
Yes. (3). Figure 15 shows an electric heat dryer installed behind the ceiling in the bathroom.
Although installed, a dryer with hot water is installed as shown in Fig. 14.
You may. 4. The sauna of the present invention has the following major features as compared with commercial products. 1). Despite the low sauna temperature of 50 ° to 70 ° C., the sauna effect is large due to the warm air circulation and the large amount of infrared rays emitted. 2). In the commercial sauna, sit on the stool installed in the room. Therefore, the temperature difference between the top and bottom of the sauna room is large. Because of this, his face was hot and his legs were cold, and there was a large difference in body temperature. For this reason, the indoor temperature is raised more than necessary for sweating. On the other hand, the sauna of the present invention is a sauna in which the body is lying down and the legs are extended, and since the body is in the warm air and infrared rays, there is no temperature difference between the body and it is sufficient at low temperature. Get sweating. The legs are extended so you can fully relax. 3). In the present invention, the face is always outside the sauna room.
Also, since hot air is circulated, the upper part of the bath is always under negative pressure.
It Therefore, cold outside air is flowing around the face, and the face is comfortable without becoming hot or stuffy. 4). A commercial sauna cannot be used if the indoor temperature is low during bathing. Therefore, it takes 20 to 30 minutes to be able to take a bath in winter. Especially in a Finnish sauna, it takes about one hour to take a bath. On the other hand, in the sauna of the present invention, since the human body is always receiving warm air from the back and bottom and entering the inside thereof, it is possible to take a bath directly if the warm air circulates. You can take a bath in about 3 minutes even in winter. 5). While commercially available box-type saunas are expensive, the sauna of the present invention is a bath option and is extremely inexpensive. 5. The warm air generator used in the clothes drying and sauna of the present invention is small and lightweight and easy to carry, and can be used for various purposes other than clothes drying and sauna. For example, the bathroom can be dried by placing it on the wash floor of the bathroom and discharging hot air into the bathroom. If you move to the room, you can also heat the room and clean the air.
