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 device usually consists of a far-infrared heater placed inside a sealed sauna box.
The temperature inside the sauna box can be controlled by turning on and off the heater with a bimetallic heater or a thermostat that uses liquid expansion.
This is done by turning it off.

In this case, the thermostat is turned on and off by detecting the temperature inside the sauna box, but the sensible temperature felt by the person entering the sauna box is calculated as: "sensible temperature = temperature inside the sauna box + radiant heat from the heater" Become. For this reason, the following problems have occurred.

(1) The sensible temperature is not only the temperature inside the sauna box, but also the radiant heat from the heater, so depending on whether the heater is turned on or off, it gets hotter or colder, making it impossible to obtain a constant comfortable temperature.

(2) Similarly, I was unable to sweat comfortably, so I had to go out of my way to go outside the sauna box and readjust the thermostat settings.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and aims to relieve the troublesome operation of sauna equipment and provide a comfortable sauna bath.

Structure of the Invention In order to achieve the above object, the present invention provides a heating means for heating the inside of a sauna box, a detection means for the heating means, and a calculation for calculating the outputs of the first detection means and the second detection means. and a comparison means for comparing the output of the calculation means with a value set by the temperature setting means, and a control means for controlling the heating means based on the output of the comparison means. For example, the user can experience a constant temperature and, as a result, enjoy a comfortable 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 includes a rear panel 2, a pair of front panels 3, a pair of side panels 4, a floor panel 5,
It is composed of a ceiling panel 6 and a door 7. A rod-shaped rear heater 8 extending vertically is housed in the center of the width direction of the rear panel 2, and rod-shaped front heaters are installed below each corner formed by a pair of front panels 3 and a pair of side panels 4. 9 is provided. The first quarter has a slat-like seat board on which the person inside the sauna box 1 can sit. 11
A crosspiece 11 is disposed close to the seat plate 1o and between the seat plate 10 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 freely closed.
A power supply box 13 is provided in which a calculation means (13a) and a control means (+ in 13) are housed. Reference numeral 14 designates an operating section, and reference numeral 15 designates a cover provided to protrude into the sauna box 1. A sensor 16 for detecting the temperature within the sauna box 1 is contained within the cover 15. 17 is a sensor that detects the temperature near the heater;
is provided inside the cover 18 of the front heater 9.

Next, the operation of the above structure will be explained with reference to the block diagram in FIG. 3 and the time-temperature characteristic diagram of each part in FIG. 4.

When the temperature setting means 14a sets the temperature to 10, the calculating means 132L performs calculations based on the temperatures detected by the sauna box temperature sensor 16 and the heater temperature sensor 17 and based on T2. Here, the sensible temperature T3
is approximated by T, ==T, +AT2.

The degree of radiant heat is constant for each heater. This is a large value for far-infrared heaters that emit far-infrared rays.

Then, the control means 13k) compares the temperature to set by the temperature setting means 141 and the sensible temperature T3 calculated by the calculating means 132L, and controls the heaters 8 and 9 to increase the sensible temperature or It is equipped with a first detection means for detecting the neighboring temperature and a second detection means for detecting the ambient temperature in the sauna box, and the output of the calculation means for calculating the output of these detection means and the temperature setting means are set by the temperature setting means. Since the heating means is controlled by a controller and stage based on the output of the comparison means, the user can feel a constant temperature, and the result is , the heater can be turned on and off like before.
By turning it off, you won't get hot or cold while taking a bath, and you won't have to worry about resetting the thermostat while taking a bath, so you can enjoy a comfortable sauna bath at a constant temperature. It is.
