Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides a sauna device, particularly a small-sized sauna device incorporated in a unit bath, and which can be used in a small-scale residence.

[Prior art]

A sauna bath consisted of a specially built large room with a heater attached to it, and the high temperature air generated by this was supplied into the room, or an electric heater was installed inside a wooden box that accommodated several people. There are things etc.

In the former case, the concrete structure itself constitutes a sauna bath, and although it can be used by a large number of people at once, it is a large-scale structure that can only be used for commercial purposes.

On the other hand, the latter is usually used by a small number of people such as a family, and the dimensions of the box that makes up the small room are 100 to 200 cm deep, 150 to 250 cm wide, and 180 to 180 cm high.
It is 200cm long and is too large to be installed in a private residence, especially a bathroom, and the households that can install it are limited to owners of very large houses, especially in urban areas. It is often difficult.

In addition, with the arrival of an aging society, health management is being considered, and as part of this, moderate exercise and the use of sauna baths are recommended.

However, at present, the number of users of sauna baths is limited to a small number of enthusiasts, and for example, sauna baths are hardly used by housewives or children.

The reason for this is that, as mentioned above, it is necessary to go to the sauna on special occasions, and the housing situation is too small to accommodate a sauna box.

[Problems to be solved by the invention]

As mentioned above, the washing areas in bathrooms installed in ordinary homes and condominiums are relatively large, and it is advantageous to be able to use these washing areas, as well as sauna baths that can be easily used by the whole family. be.

However, conventional commercial sauna baths cannot be used by just anyone, and mobile sauna baths, which are used by ordinary households that own a small number of large houses, have relatively large boxes. can be,
There were problems in that it was too large to be used in a general household consisting of a normal-sized house and that it could not be installed in the same location as the shower.

[Purpose of the invention]

As mentioned above, conventional sauna baths are limited to those that are built into buildings or relatively large ones that use a box body, and have the problem of being suitable only for large houses, but the present invention solves these problems. The primary purpose is to solve problems.

Recently, baths installed in condominiums and business hotels often use so-called "unit baths," which are molded from synthetic resin and have a bathtub and washing area integrated into one.

The present invention has focused on this, and a second object of the present invention is to provide a unit bath in which a miniaturized sauna heater can be incorporated into the previous unit bath, or in which the sauna heater can be incorporated.

[Summary of the invention]

To achieve the above object, a small sauna device according to the present invention is a bath in which a bathtub and a washing area are integrally molded from synthetic resin, and a heater is arranged in a corner of the washing area, and a drainboard is arranged in the front part of the bath, The heater consists of a reflecting plate, a heating body provided in front of the reflecting plate, and a heat-resistant glass facing the reflecting plate so as to house the heater inside, forming a vertically oriented duct. A fan is provided to draw in air and exhaust the heated air from below, and the lower part of the drainboard is used as a part of the heated air passage to exhaust the heated air.

That is, in the present invention, a sauna heater is installed in the corner of the washing area of a combined body in which a bathtub and a washing area are integrally molded from synthetic resin, and the lower part of a drainboard placed in the washing area is heated with hot air. It is a passageway.

As the sauna heater, for example, the device described in Japanese Patent Application No. 152,617/1988, which was already proposed by the present inventor, can be used.

The above-mentioned invention provides a heat-generating section consisting of a reflecting plate, a transparent wall provided in front of the reflecting plate, a heating element provided on the reflecting plate, and an air blower that blows air between the reflecting plate and the transparent wall. 1, a ventilated floor placed in front of the lower part of the heat generating part, and a flexible reflective wall forming a small chamber.

The technical concept of the sauna device is that infrared rays are radiated from the front of the human body, reflected by surrounding flexible reflective walls, and radiated from the back and sides of the human body.

Further, the front surface of the heater forms a kind of duct, and the air sucked in from the top is heated while passing through the front surface of the heater. Hot air is then blown out from beneath the feet upwards from the bottom of the drainboard installed in the washing area. The hot air ejected from the feet rises along the human body, is sucked into the fan through the intake hole provided in front of the head, and descends through the duct in front of the heater as described above.

Since heaters are usually small, they cannot heat the entire bathroom to a temperature suitable for a sauna bath. Therefore, it is necessary to heat the air in a small area where the human body is located. Therefore, it is a good idea to surround the front of the heater with a small chamber. This small room is preferably constructed with a reflective wall so that infrared rays are emitted from the back and sides of the human body.

When a small room constructed of reflective walls is used as a regular bath, it is preferably placed in a corner of the bath, and in this sense a reflective curtain is used.

Lightweight partitions can be used instead of curtains if the reflective walls are easily foldable. This partition may be, for example, a board made of synthetic resin foam, or a lightweight panel made of cardboard paper as a core material and covered with a reflective synthetic resin sheet. In addition, a board made of synthetic resin foam or cardboard paper is used as a core material, a synthetic resin layer is formed on the surface of the board, and a reflective synthetic resin film is pasted on the side facing the human body, or a reflective coating is used. A material with a film formed thereon can be used.

The appropriate place to install the heater is in the triangular corner of the washing area. As will be described later, the heater has a triangular shape in plan view, and can be easily installed as is, and wiring is easy.
Also, since it only occupies a small corner, it does not make the washing area feel cramped.

The washing area needs to form a duct through which hot air blows out. Specifically, a drainboard is provided in a washing area, and hot air heated by a heater is blown between the lower surface of the drainboard and the upper surface of the washing area, and the air is blown from the bottom of the drainboard toward the top.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of a unit bath in which a small sauna device is installed, and FIG. 2 is a plan view of the same.

In addition, Fig. 3 is a sectional view taken along the line A-A in Fig. 2 showing the state of use of the sauna equipment, and Fig. 4 is a sectional view taken along the line B-B in Fig. 3.

A heater 6 is installed in a corner of the washing area 4,
A flexible reflective wall 8 hangs down from the ceiling 7 so as to be openable and closable. A drainboard 9 is provided above the washing area 4. In addition, 10 is a drainage hole.

The heater 6 has a reflector 16 provided inside a main body 15, and a heating element 1 at the center of the front surface of the reflector 16.
A plurality of 7 are provided in the vertical direction. A heat-resistant glass 18 is provided on the front surface of the heating body 17 and closes the front surface of the main body 15.
A duct 19 is formed in the space between the reflector 16 and the heat-resistant glass 18.

A fan 20 is installed at the top of the duct 19.
(Shirotskovan) is provided. Air is sucked through the opening 21 on the front side of the fan 20, discharged into the duct 19, heated by the heating element 17, and discharged through an outlet 2 formed at the lower part of the heat-resistant glass 18.
2 to the lower part of the drainboard 9. The direction of the support rod fixing the upper plate of the drainboard 9 is determined so that the hot air blown out from the lower part of the duct 19 is guided to the lower surface of the drainboard 9.

The space between the back of the reflector 16 and the main body 15 is filled with a heat insulating material such as glass wool. Further, an evaporation plate 24 is provided at the lower part of the duct 19, and hot air is caused to collide with the water contained in the evaporation plate 24 to generate steam. Further, a mesh 25 is provided on the front surface of the heat-resistant glass 18 to prevent the glass from being damaged.

Although various types of heaters can be used as the heater 17, it is preferable to use one that can emit a large amount of far infrared rays, such as a ceramic heater. A suitable ceramic heater is one in which a nichrome wire is used as a heat generating source to heat the heat radiating portion of the ceramic molded body.

The fan 20 is preferably of a type that is small and capable of blowing a large amount of air, and a Sirotskov fan is suitable for this purpose. The air volume of this fan 20 can be appropriately adjusted in consideration of the indoor temperature.

When using the small sauna device of the present invention having the above configuration, the front part of the heater 6 is covered with the flexible reflective wall 8 to form a small section, the heating element 17 is energized, and the fan 20 is is driven to circulate the air within the small compartment and raise its temperature. The temperature inside the small compartment is

heats the front and back of the human body by sitting in front of it. The user 26 sweats considerably due to the above operation, but after that, the user 26 uses a bath, shower, etc. in combination to cleanse the human body and sweat profusely as in the case of using a normal sauna bath. According to the results of actual use, heating the human body from behind, and using a bath to sweat and heat the body when sweating causes sweating in a short time and provides a good refreshing feeling. You can feel it.

In addition, when the sauna device of the present invention is continuously used, the skin surface becomes smoother and more glossy, which makes it easier for cosmetics to adhere to it, probably as a result of promoting the excretion of subcutaneous waste products. It has been confirmed that this will happen.

As the heating element 17, five 400W ceramic heaters were used, and single-phase three-wire 200V was supplied. The amount of electricity used in this case was 3KWH.

In addition, in this embodiment, the bathtub 3 and the washing area 4
Although we have described a sauna device in which the heater 6 is built into a unit bath that is integrally molded with synthetic resin, it is also possible to integrally mold the heater case and the hot air guide part that constitutes a part of the drainboard. is clear.

Furthermore, as shown by the dotted line in FIG. 2, a structure in which the part where the heater is installed protrudes slightly outward from the washing area can also be used.

The unit bath is usually integrally molded from synthetic resin, but may also be formed from a metal plate such as a stainless steel plate.

〔Effect of the invention〕

The small sauna device according to the present invention is a bath in which a bathtub and a washing area are integrally molded from synthetic resin.
A heater is placed in the corner of the washing area, and a drainboard is placed in front of it, and the heater consists of a reflective plate and a heating element installed in front of it, and a piece of heat-resistant glass that faces the reflective plate and houses the heating element inside. A fan is provided in this duct to draw in air and exhaust heated air from below, and the lower part of the drainboard is connected to a passage for heated air. It is constructed so that heated air is partially exhausted, and the following effects can be achieved.

(1) Since the heater is equipped with heat-resistant glass on the front and a heating element behind it, the user in front of the heater receives a large amount of heat rays. In addition, while the air passes through the inside of this heater as a duct, it is heated to a high temperature, and this heated air is supplied to the bottom of the drainboard, and hot air that is hotter than the user's body temperature is ejected from the user's feet, which is heated to a high temperature. As it rises and circulates while enveloping the whole body, it can promote large amounts of sweat.

In addition, since heat-resistant glass forms part of the duct, it is constantly cooled by the large amount of air that passes through the duct, preventing localized high temperatures and maintaining a relatively low temperature. - If you come into contact with it, you will not be seriously injured.

(2) Since the heater is extremely compact, it can be incorporated into a conventional unit bath. This means that unit baths already installed in housing complexes, business hotels, or general residences can be converted into sauna baths. Therefore, even housewives and children of ordinary households who have not been accustomed to sauna baths can use sauna baths with peace of mind.

Furthermore, if a business hotel is equipped with the sauna device according to the present invention, office workers who are tired from daytime work can easily relieve fatigue before going to bed.

(3) The present invention can be implemented without significantly changing the structure of the unit bus.

(4) In the sauna device of the present invention, it is also possible to integrally incorporate a heater in a factory, and by incorporating a unit bath into a building, the sauna device can be easily installed.

(5) There is a regular bath and a sauna bath, so if you sweat in the sauna bath, you can soak in the regular bath to warm up, and then use the sauna bath, which is more effective than a regular sauna. You can use it.

(6) Since the sauna device of the present invention is installed in a bathroom, it is suitable to use a shower, and it is possible to selectively use three different usage conditions: a sauna bath, a regular bath, and a shower. Extremely effective.
