Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply device for a sauna, and more particularly to a power supply device for a sauna suitable for use in a dry sauna using a large sauna stove.

[0002]

2. Description of the Related Art In a private room type dry sauna used in general households and various facilities, a sauna stove using a heater as a heat source is used to keep the room temperature at, for example, 80 degrees.
Although it is heated to a high temperature of ℃ to 110 ℃, the conventional sauna stove is normally powered by AC100V 1.3K
Electric heaters around W are used, and when the sauna room is large and requires a large amount of heat source, a large sauna stove in which the number of heaters is increased is used.

Therefore, for example, in the case of a large sauna stove using three 1.3 kW heaters, the total is 3.9 K.
Since it requires W power, it is not possible to take this power supply from one household outlet in terms of capacity. Therefore, conventionally, electrical work for three-phase (three types) power supply was performed and a dedicated outlet was used. It was built and had a sauna stove plug connected to it.

[0004]

As described above, when using a large sauna stove, it is necessary to carry out electrical work without exception. For example, when the sauna is to be housed in a general household or is displayed in a model room. If there is no three-phase power supply at the installation site, it will be necessary to request electrical work in advance, or to carry out a separate power supply work together with people involved in electrical work on the day. If you forget, there is a problem that you can not actually use (drive) even if you install a sauna,
In addition, due to lack of manpower recently, electrical work was delayed due to the lack of dispatch of people involved in the construction, even if delivered it could not be operated on the spot, or the delivered sauna would be installed in a state where it could not be used for many days. In some cases, there was a problem that greatly affected the sales of saunas.

Therefore, the technical problem of the present invention is that for the time being, even if a three-phase power supply is not installed, a household AC100 is used.
It is an object of the present invention to provide a power supply device for a sauna, which allows a sauna to be used safely as usual until a large sauna stove is operated by using a V power supply and electric work is performed.

[0006]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows. In a sauna where the heater of the sauna is composed of multiple heaters,

(1) Each of the above heaters should be provided with a power supply circuit which can be connected to a separate household power supply via an earth leakage breaker and a magnet switch.

(2) In any of these power supply circuits,
An abnormality monitoring circuit that monitors the safe driving of the sauna stove,
A control device having a magnet for operating each of the above magnet switches is incorporated, and when the abnormality monitoring circuit detects an abnormality, each magnet is activated to open the magnet switch of each power supply circuit.

(3) The abnormality monitoring circuit is composed of a thermal fuse and a thermoswitch.

[0010]

The above means operates as follows. The element of (1) above is that each heater of the sauna stove has a separate household power source (household outlet, AC100V).
If the total power of these heaters is within the allowable range of the main circuit breaker, each heater will be heated and the sauna will operate normally without the need for three-phase power supply work. In addition, when a leak occurs in the electric system including these heaters, the leak breaker connected in each power circuit operates, so it is possible to reliably prevent the most dangerous leak accident in the sauna. To do.

According to the above-mentioned element (2), when various abnormalities occur in the heater of the sauna stove, as soon as the abnormality monitoring circuit detects the abnormalities, the magnet is excited to operate and provided in the power supply circuit of each heater. Since each magnet switch is opened and each heater is turned off, it is possible to reliably prevent a fire accident or the like in the sauna due to an abnormality in the heater.

The element of (3) above immediately detects temperature abnormality of each heater and immediately cuts off energization to the heater, so that fire accident of the sauna due to heater failure is prevented and used safely. To enable that. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
