Description

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

Configuration of conventional examples and their problems Recently, attention has been paid to the positive effects that sauna bathing has on health and beauty, and small box-type sauna devices have been gaining popularity at home. This dish sauna device usually consists of a far-infrared heater placed inside a sealed sauna box, and the temperature inside the sauna box is controlled by turning the heater on and off with a thermostat. ing.

It is also common to have a time switch that controls the energization time and an interior light switch that turns the interior lights on and off.

However, with only radiant heaters such as far-infrared rays, the temperature distribution inside the sauna box is poor, and warm air accumulates at the top, causing cold feet, so in recent years, hot air fans have been installed at the feet. However, insufficient consideration was given to the safety of the warm air fan, resulting in the following problems.

(1) When the blower loses its function, the heater part generates abnormal heat, which may burn out the wood around the hot air fan and cause a fire.

(2) To prevent the above-mentioned dangers, some devices are equipped with overtemperature rise prevention devices, but depending on conditions such as the power supply voltage and the temperature inside the sauna box, they may operate even under normal usage conditions, and the hot air blower may not function properly. There is something to lose.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and aims to provide a sauna device that ensures the operation of the overtemperature rise prevention device and is highly safe and reliable.

Structure of the Invention In order to achieve the above object, the present invention provides heating means for heating the inside of the sauna box, including a blower that blows air both to the heater located in the duct and to the overtemperature rise prevention device located on the top surface of the duct. It is equipped with a hot air fan consisting of a cover that covers the duct and the blower, and according to this configuration, the overtemperature rise prevention device is used because air at the temperature inside the sauna box is sent by the blower to cool the sauna box. The influence of heat from the heater can be ignored, and the temperature inside the sauna box is always maintained. In the unlikely event that the blower stops blowing due to an abnormality, the temperature will rise rapidly due to the heat from the heater and the temperature will quickly exceed 1''! "L'""Function f: 'J if tD T・
2:1, the overheat prevention device maintains a stable temperature under normal usage conditions, so there is no need to worry about malfunctions, and in the event of an abnormality, the hot air fan is equipped with an overheat prevention device that operates quickly and reliably. It is possible to obtain a sauna device equipped with the following.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Fig. 1, 1 is a sauna box, and this sauna box 1 has a rear panel 2 and a pair of front springs/
It is composed of L/3, a pair of side panels 4, a floor spring/I15, a ceiling spring/I/6, and a door 7. A rod-shaped rear heater 8 extending vertically is housed in the widthwise center of the rear spring (v2), and a rod-shaped rear heater (8) that extends vertically is housed in the rear spring (v2). A heater 9 is provided. 10a is a pair of pedestals, and this pedestal 10a is attached to a side spring/L'4, and a drainboard-shaped seat plate 10b is installed. Reference numeral 11 denotes a crosspiece that is disposed close to the seat plate 10b and between the seat plate 10b and the rod-shaped rear heater 8, and this crosspiece 11 prevents the user from coming into contact with the rear heater 8.

Reference numeral 12 denotes a hot air fan, and this hot air fan 12 is located below the seat plate 10b, and contributes to circulating the air inside the sauna box 1 and raising its temperature.

Further, the configuration of the hot air fan 12 will be explained in detail with reference to FIGS. 2 and 3. The hot air fan 12 includes a motor 14 and a duct 15 installed on a base 13, and
A heater 17 wound around a manpower 16 is inserted inside. Further, a blower 18 having a diameter larger than the diameter of the duct 15 is attached to the motor 14.
On the top of the is a thermostat 1 with a temperature overheat prevention device.
9 and a temperature fuse 20 are installed.

A cover 21 covering the above components is installed on the base 13.

To explain the operation of the above-mentioned configuration, first, when the user turns on electricity to the sauna apparatus, the heater 8.9 is energized, and the heater 17 and motor 14 are also energized. As a result, the heater 17 generates heat and the motor 14
The blower 18 is rotated to blow air to the heater section in the duct 15 to produce warm air. Here, the duct 15 is heated by the radiant heat of the heater 17, and the conductive heat further heats the thermostat 19 and the temperature fuse 20. However, according to the configuration of the present invention, since the diameter of the blower 18 is larger than the diameter of the duct 15, the wind flows along the outer periphery of the duct 15.
9 and temperature fuse 2o can be cooled.

In the unlikely event that the blower 18 stops rotating and blowing air due to an abnormality in the motor 14, the upper surface of the duct 16 will be rapidly heated by the radiant heat of the heater 17 and the convection heat in the duct 15, and further by conductive heat. The thermostand 19 operates quickly. And further thermostat 19
If there is an abnormality and the temperature fuse 20 does not operate, the temperature fuse 20 is activated.

Effects of the Invention As described above, according to the present invention, since the overtemperature rise prevention device is configured to be constantly cooled by the air blown by the blower, the temperature remains stable under normal usage conditions, which may result in malfunction. There are no 10 settings, and in the unlikely event that the blower stops, the temperature overheat prevention device will work quickly and reliably, making it possible to provide a safe and highly reliable sauna device at a low cost. It is something.
