Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sauna device for general household use.

Conventional Structure and Problems Recently, attention has been paid to the positive effects that sauna bathing has on health, and small box-type sauna devices have become popular at home. This type of sauna equipment usually consists of a far-infrared heater placed inside a sealed sauna box, and the temperature inside the sauna box is controlled by turning on the heater with a thermostat that uses bimetal or liquid expansion. This is done by turning it off. In other words, in conventional sauna equipment, the temperature inside the sauna box rises when the heater is turned on, and the temperature inside the sauna box falls when the heater is turned off. However, it had the following problems.

(1) The temperature inside the box fluctuated greatly when the heater was turned on and off, making it difficult to cast at a predetermined temperature.

(2) When the heater is on, the temperature inside the box is almost uniform due to heat radiation from the heater, but when the heater is off, high-temperature air moves to the top of the box due to natural convection, and the temperature increases. As the low-temperature air moves to the bottom of the box, there is a temperature difference between the top and bottom of the box, causing a phenomenon of hot heads and cold feet.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems and aims to reduce the temperature difference between the upper and lower parts of the sauna box.

Structure of the Invention In order to achieve the above object, the present invention includes a sauna box having several doors on the front that can be opened and closed with hinges,
A rod-shaped heater is arranged at each front corner of the sauna box, and a cover is provided that protrudes inward and is located above the rod-shaped heater located on the opposite side of the door opening, and within this cover, This system is equipped with a sensor that detects the air temperature inside the sauna box and controls the heater. According to this configuration, even when the door is opened to take a sauna bath, the sensor prevents the temperature inside the sauna box from decreasing. Because it instantly detects and turns on the heater,
The drop in temperature inside the sauna box can be suppressed to a minimum, and the temperature difference between the upper and lower parts of the sauna box can also be reduced, so that a comfortable sauna bath can be enjoyed immediately after taking a bath.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 1 is a sauna box, and this sauna box 1 is composed of a rear panel 2, a pair of front panels 3, a pair of side panels 4, a floor panel 6, a ceiling panel 6, and a door 7. f. A rod-shaped rear heater 8 extending vertically is housed in the center of the width direction of the rear panel 2, and a rear heater 8 is housed in the rear panel 2 at the bottom of the corner formed by a pair of front panels 3 and a pair of side panels 4. A rod-shaped front heater 9 is provided. 10 is a slatted seat board on which a person entering the sauna box 1 can sit. 1
Reference numeral 1 denotes a crosspiece disposed close to the seat plate 10 between the seat plate 1Q and the rod-shaped rear heater 8, and this crosspiece 11 prevents people from coming into contact with the rear heater 8.

The door 7- is attached to one front panel 3 by a hinge 12 so as to be openable and closable, and the other front panel 3 is provided with a power supply box 13.
Components for controlling the temperature of the sauna box 1 are housed in the sauna box 1. 14 is an operation knob provided on the power supply box 13;
Reference numeral 16 denotes a cover located above the bar-shaped front heater 9 located on the opposite side of the hinge 12 of the door 7 and protruding into the sauna box 1. A sensor 16 such as a thermistor is provided to detect the air temperature within the air conditioner 1.

The operation of the above configuration will be explained next.

Without hesitation, open door 7 and enter Sauna Hox 1.
The person receives heat radiation from a rear heater 8 and a pair of front heaters 9. On the other hand, the temperature of the air flowing along the surfaces of the rear heater 8 and front heater 90 increases as the heat from the heaters 8.9 is transferred through convection heat transfer, so that the temperature of the air inside the sauna box 1 also gradually increases.

This air temperature is sensed by a sensor 16, and a control circuit housed in a power supply box 13 turns on and off a rear heater 8 and a pair of front heaters 9, thereby controlling the temperature inside the sauna box 1.

Here, the sensor 16 is located in the cover 16 located above the front heater 9, and the heat capacity of the sensor 16 itself is very small, so it can be sensitively detected.For example, when taking a sauna bath, Even when the door 7 is opened, the sensor 16 immediately detects a drop in the temperature inside the sauna box 1 and turns on the front heater 9, so the drop in temperature inside the sauna box 1 can be kept to a minimum. , therefore sauna box 1
It is possible to control the temperature difference between the upper and lower parts of the sauna to a small extent, and as a result, you can enjoy a comfortable sauna bath.

FIG. 3 shows the temperature distribution over time in the sauna box in one embodiment of the present invention, and FIG.
The figures show the temperature distribution over time in a conventional sauna box. In these figures, the solid line is the temperature in the lower part of the sauna box, and the broken line is the temperature in the lower part of the sauna box. As is clear from these figures, in one embodiment of the present invention, the temperature of the upper and lower parts of the sauna box can be brought close to a predetermined temperature in a uniform state.

Effects of the Invention As described above, according to the present invention, rod-shaped heaters are arranged at the front corners of the sauna box, and the rod-shaped heaters are positioned above and inward on the opposite side of the door hinge. A protruding cover is provided, and within this cover is a sensor that detects the air temperature inside the sauna box and controls the heater, so even when the door is opened to take a sauna bath, the sensor does not activate the sauna hook. It instantly detects a drop in the temperature inside the sauna box and turns on all the heaters, thereby minimizing the temperature drop inside the sauna box and reducing the temperature difference between the top and bottom inside the sauna box. This has the excellent effect of allowing you to enjoy a comfortable sauna bath immediately after taking a bath.
