Description

[Detailed description of the invention] 〔Technical field〕 This invention relates to saunas.

[Background technology]

In recent years, as interest in health has increased, health equipment has been actively developed. One such device is a sauna that can be used at home.

However, conventional saunas are not very user-friendly due to the following points.

Even if the sauna is for home use, the temperature inside the sauna must be kept quite high (80 to 110°C) when taking a bath. An electric heater is used as a heat source to heat the sauna room. Therefore, it takes 30 to 50 minutes after starting the drive to reach the temperature at which bathing is possible. Therefore, it is not possible to take a bath directly in the sauna whenever you want. For example, it is not possible to take a bath immediately after playing sports, or a busy businessman cannot take a bath immediately after returning home.

In addition, if multiple people are using the electric heater, the last person must turn off the electric heater, but safety management such as always checking who is the last one is necessary.

[Purpose of the invention]

In view of the above circumstances, it is an object of the present invention to provide an easy-to-use sauna that allows you to take a bath at any time you want and does not require management to stop the heater.

[Disclosure of the invention].

In order to achieve the above object, the present invention provides a sauna equipped with an electric heater as a heat source, characterized in that a drive timing setting means is provided for setting a drive start time and a drive stop time of the electric heater. This is the summary.

Hereinafter, one embodiment of the sauna according to the present invention will be explained in detail with reference to the accompanying drawings. Fig. 1 shows the electric system around the drive timing setting means for the electric heater in one embodiment of the sauna according to the present invention. This is a rough version of the block diagram. Figure 7 shows this sauna cut away to show the inside of the room.

Sauna 21 uses an electric heater (electric stove) as a heat source.
It has 3. Electric heater 3 is placed within heater enclosure 22. A sauna stone may be used to soften the radiant heat from the electric heater 3. Switches and timers for driving the electric heater 3 are provided in an outdoor control box 23.

The sauna 21 is provided with drive timing setting means for setting the drive start timing and drive stop timing of the electric heater 3.

This drive timing setting means includes an ON timer 5 and an OFF timer 6 attached to the control box 23. The ON timer 5 is for setting the timing at which the switch (for example, a relay contact) 2 located between the power source 1 and the electric heater 3 is closed, while the OFF timer 6 is for
This is for setting the timing to open the closed switch 2. When the ON timer 5 changes from the reset state to the set state, the OFF timer 6 enters the reset state only for a set delay time. When the OFF timer 6 is in the reset state, the switch 2 is closed, and when the OFF timer 6 is in the set state, the switch 2 is open. The bather sets the delay time of the ON timer 5 so that the switch 2 closes 30 to 50 minutes before the desired time to take a bath, and the time when the switch 2 opens is after the last person has finished bathing. OF
Set the delay time of F timer 6.

Next, how the electric heater 3 is driven by the switch 2, ON timer 5, and OFF timer 6 will be explained with reference to the time chart shown in FIG.

At time TI (for example, before dispatch), the ON timer 5 and OFF timer 6 are set. The delay time is set to time TWA so that the ON timer 5 enters the cent state at time T2 (30 to 50 minutes before the desired bathing time) and is brought into the reset state. On the other hand, the delay time of the OFF timer 6 is changed from the time T2 when the switch 2 is closed to the time T3 when the last person has finished bathing.
The time between T. Set to 8.

When the ON timer 5 goes into the set state at time T2, the OFF timer 6 goes into the reset state as the ON timer 5 operates at this time. Then, the switch 2 is closed and the electric heater 3 starts to be driven. After 30 to 50 minutes, the sauna 21 room will reach bathing temperature. For example, if you set the time T2 at which the switch 2 is closed to 30 to 50 minutes before returning home, you will be able to take a bath in the sauna 21 immediately after returning home for 6 hours T2.
After oN elapses, OFF timer 6 returns to cent state, so
Switch 2 is now in an open state.

Therefore, the driving of the electric heater 3 is automatically stopped. However, by this time everyone has finished bathing. There is no need for the last person to stop the driving of the electric heater 3.

Note that the sauna 21 detects the temperature inside the sauna 21 with a temperature detector 8, turns off the electric current of the electric heater 3 while the set temperature is reached (for example, by opening the switch 2), and turns it off again when the temperature drops. It is equipped with an automatic temperature control means 9 that automatically causes current to flow.

Microscopically, at this time, the driving of the electric heater 3 has stopped, but such a temporary stop is a so-called pause, and in this specification, the driving of the electric heater 3 is stopped. It doesn't mean a complete stop.

In this way, in the sauna 21, you can take a bath whenever you want by just setting the ON timer 5 and OFF timer 6 once, and the electric heater 3 automatically stops driving at a predetermined time, making management easy. There's no need to do it. Therefore, the sauna 21 becomes extremely convenient to use.

Next, other embodiments will be explained.

FIG. 2 is a block diagram of the electrical system around the drive timing setting means in another embodiment of the sauna according to the present invention. FIG. 5 is a time chart of this electrical system block diagram.

There are two switches 2.2 between the power supply 1 and the electric heater 3.
' are inserted in series, and ON timers 5 and O, respectively.
It is designed to be opened and closed by FF timer 6. That is, switch 2 is open when the ON timer is in the reset state, and closed when the ON timer is in the set state. The switch 2' is closed when the OFF timer 6 is in the reset state, and is closed when the OFF timer 6 is in the cent state.

At time Tl, the ON timer 5 and OFF timer 6 are set as follows. The delay time is set to time TwA so that the ON timer 5 is set to the set state at time T2 (30 to 50 minutes before the desired bathing time), and the ON timer 5 is set to the reset state. On the other hand, O
The delay time of the FF timer 5 is calculated from the time TWA and the time T2 when the switch 2 closes to the time T when the last person has finished bathing.
The time T between 3. Set the time to match H. At this time, switch 2' is closed but switch 2 is open, so electric heater 3 is not driven.

After time TwA has elapsed, the ON timer 5 is set.

Then, both switches 2 and 2' are closed, and the electric heater 3 starts to be driven. After 30 to 50 minutes, the sauna 21 room will reach bathing temperature. For example, if the switch 2 is set to close 30 to 50 minutes before returning home, the user can take a bath in the sauna 21 immediately after returning home.

Furthermore, time T. After N elapses, the OFF timer 6 returns to the set state. Therefore, although the switch 2 remains closed, the switch 2' is opened and the driving of the electric heater 3 is automatically stopped.

FIG. 3 is a block diagram of the electrical system around the drive timing setting means in another embodiment of the sauna according to the present invention.

The basic operation is the same as the embodiment shown in FIG.

In the embodiment shown in FIG. 1, the ON timer 5 closes the switch 2 via the OFF timer 6, but in this embodiment, the ON timer 5 directly closes the switch 2. different.

In the embodiment shown in FIG. 6, the drive start timing and drive stop timing of the electric heater 3 are set in the time setting device 12 by time. The setting signal of the time setter 12 is sent to the comparison controller IO. On the other hand, this comparison controller 1O is also sent a real time signal from a time signal device (for example, an IC clock) 11. Comparison controller 1
0 compares the set signal and the real time signal, closes the switch 2 when it is time to start driving, and opens the switch 2 when it comes time to stop driving. Although this embodiment has a high-class circuit configuration and is slightly more expensive, it is convenient because it allows direct setting by time.

The switch 2 in the above embodiment may be the main switch of the sauna 21, or may be a switch provided in series after the main switch.

This invention is not limited to the above embodiments. It goes without saying that the embodiments shown in FIGS. 2 and 3 may also be provided with automatic temperature control means. The delay time of the OFF timer may be fixed to a constant time.

〔Effect of the invention〕

The sauna according to the present invention is provided with drive timing setting means for setting the drive start timing and drive stop timing of the electric heater for the heat source. Therefore, you can take a bath when you want to take a bath, and there is no need to control whether or not to stop the heater, making it easier to use.
