BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam sauna apparatus, and more particularly, to a steam sauna apparatus for improving the accuracy of controlling the temperature in a sauna room at the start of operation.

[0002]

2. Description of the Related Art A steam sauna apparatus which performs heating and humidification by injecting high-temperature steam obtained by a steam generating means into a room and which controls a room temperature by providing a thermistor for detecting temperature in the sauna room is known. Then, the set temperature input by the temperature input means is compared with the detected value of the thermistor, and the steam generating means is controlled so that the room temperature becomes equal to the set temperature. In the above steam sauna device, it is sometimes difficult to control the temperature according to the user's request due to the effect of the fluctuation of the detected temperature based on the uneven temperature distribution in the room. Is provided with an air circulation device having an opening. This air circulation device is provided with a blower in the air circulation path, circulates and stirs the air in the sauna room, and makes the temperature distribution in the room uniform, thereby improving the accuracy of the temperature control (for example, in the case of actual open flat). 2-88
No. 638).

[0003]

However, at the start of the operation of the steam sauna apparatus, since the temperature of the equipment in the sauna room is lower than the steam temperature, dew condensation occurs on the surface including the thermistor for detecting the temperature.

The thermistor has a large difference from the room air temperature due to the water droplets due to the condensation, and as a result, accurate temperature detection is not performed, and thus stable temperature control is not performed.

[0005]

In order to solve the above problems, a steam sauna apparatus is provided in which a small cross section is provided in an air circulation path, and a thermistor is disposed at a position exposed to high-speed airflow by the small cross section. Was configured.

[0006]

The water droplets that have condensed on the surface of the thermistor are blown off by the high-speed airflow through the small cross section, and the temperature of the thermistor becomes almost equal to the temperature of the air in the sauna room. Therefore,
The detected value of the thermistor substantially corresponds to the temperature of the room air. The set temperature input by the temperature input means is compared with the detected value of the thermistor, and the steam generating means is controlled so that the room temperature becomes equal to the set temperature. .

FIG. 1 is a longitudinal sectional view of a first embodiment of a steam sauna apparatus according to the present invention, and FIG. 2 is a longitudinal sectional view of a main part of the second embodiment.

In FIG. 1, a steam sauna apparatus has a steam generating means 2 having an opening 1 a at one end of a sauna room 1.
And openings 1b, 1 in the upper and lower parts of the sauna room 1.
An air circulation device 3 having c is provided.

The steam generating means 2 includes a tank 2a for storing water, a heater 2b for heating water in the tank 2a, a water supply pipe 2c, a drain pipe 2d, and the like. The heating of the heater 2b is controlled by a control device (not shown) to generate high-temperature steam, and the solenoid valves 2e and 2f provided in the water supply pipe 2c and the drain pipe 2d respectively have a level (not shown) for detecting a water level. The water level in the tank 2a is kept constant based on the signal of the meter.

The air circulating device 3 comprises an air circulating passage 3a and a blower 3b provided in the air circulating passage 3a. The air circulating device 3 takes in the air in the upper part of the sauna room 1 and discharges it to the lower part of the sauna room 1, The air in the sauna room 1 is circulated and stirred. As a result, the air temperature in the sauna room 1 becomes uniform.

The air circulation path 3a is provided with a small cross section 3c having a reduced cross section diameter in a part of the air circulation path 3a.
thermistor 3 at a location near the downstream side of
The temperature sensing unit of d is provided.

The position of the thermistor 3d can be arbitrarily selected within a range exposed to a high-speed air flow, such as in the small section 3c, and the small section 3c is located in the air circulation path 3a. Can be selected arbitrarily.

In FIG. 2, the air circulation path 3a is provided with a small section 3c formed of an orifice at a part thereof, and the temperature of the thermistor 3d is set at a position exposed to the high-speed air flow near the small section 3c or downstream thereof. A sensing unit is provided. The thermistor 3d can be integrated into an orifice, and the orifice mounting position can be arbitrarily selected in the air circulation path 3a.

The thermistor 3d is connected to a control device (not shown), and the control device controls the steam generating means 2 so as to adjust the temperature to a target temperature inputted by a remote control command device (not shown).

The operation of the steam sauna apparatus having the above configuration will be described below.

When the operation of the steam sauna apparatus is started, the water level in the tank 2a of the steam generating means 2 is adjusted, and the heater 2b is energized to generate high-temperature steam. 1a.

At the same time, the blower 3 of the air circulation device 3
b is driven, and the air in the sauna room 1
Is discharged to the sauna room 1 through the air circulation path 3a to the lower opening 1c.

As a result, the high-temperature steam supplied from the steam generating means 2 and the air heated and humidified by the high-temperature steam are circulated and agitated, and the temperature in the sauna room 1 is made uniform.

A high-speed air flow is generated in the small section 3c in the air circulation path 3a, and the high-speed air flow reaches near the downstream side of the small section 3c. The temperature sensing portion of the thermistor 3d receives the high-speed air flow, and the high-speed air flow blows off the dew on the surface of the thermistor 3d to prevent the formation of water droplets on the surface of the thermistor 3d, and sufficient heat transfer is performed.

[0021]

[Effects of the Invention] As described above, according to the present invention,
A steam sauna device is constructed by providing a small cross section in the air circulation path and arranging a temperature sensing part of the thermistor at a position exposed to the high speed air flow by the small cross section. Blows off condensation on the surface of the thermistor to prevent the formation of water droplets and supplies sufficient heat to the thermistor.

Therefore, the surface temperature of the thermistor substantially follows the temperature of the passing air in the air circulation path, and enables highly accurate temperature control. As a result, it is possible to avoid temperature fluctuation due to control instability due to feedback delay and abnormal operation due to temperature detection error, thereby enabling highly accurate temperature control.
