Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electric sauna, particularly an electric sauna for home use.

[Background technology]

Some electric saunas are equipped with a heating time timer that allows you to set the length of time the heat source is energized, as shown in Japanese Utility Model Application Publication No. 61-42928, etc.; Because there was no reservation timer to set whether to start energizing the heat source, the room temperature in the sauna room would rise to the appropriate temperature even if you wanted to take a sauna bath immediately after returning home, or when you woke up. I had to wait for the preheating time.

[Purpose of the invention]

The present invention has been developed in view of these points, and its purpose is to create an electric sauna that allows you to take a bath without waiting for preheating time by setting the time to start energizing the heat source. It is on offer.

[Disclosure of the invention]

Therefore, the present invention provides a heating time timer for setting the time for energizing the heat source, and a time for setting the operation start time of the heating time timer, which is the start time for energizing the heat source, and a reservation for activating the heating time timer at the set time. This device is characterized by being equipped with a timer, so that the user can start energizing the heat source for the time set by the heating time timer at the time the user wants to take a bath. .

The present invention will be described in detail below based on the illustrated embodiment. As shown in FIG. A box-shaped main body 1 is provided with a door 2 at an opening on one side thereof, and a slat-shaped seat 10 and a backrest 11 on which the user sits are installed inside the sauna room. , heaters H ₁ and H ₂ are disposed on the inner wall and below the seat portion 10, respectively. Furthermore, a speaker SP connected to amplifier box A is installed on the ceiling.

Handles 21 and 22 are attached to the outer and inner surfaces of the door 2 to which the window 20 is attached, respectively. Both handles 21 and 22 are fixed so as to sandwich the door 2 by a mounting screw 23 that is screwed from the handle 22 on the inner surface of the door 2 through the door 2 and into the handle 21 on the outer surface of the door 2. The handle 22 on the inside of the door 2
is provided with a recess 24 as a stopper and, as shown in FIG. 6, a stopper 25 for allowing the book B to be hung upright.

A control block 3 for controlling both the heaters H ₁ and H ₂ is disposed in a stile 15 above the opening in the main body 1 where the door 2 is disposed. Frame 1
Panels 30, 3 arranged on the outer and inner surfaces of 5, respectively.
This control block 3, which exposes an operating section and a display section at 1, is an operation control circuit C shown in FIG.
It is constructed by mounting a DC power supply circuit D, etc. on a printed circuit board 32, and the outer panel 3
0, a power switch configured with a breaker
SW, indoor temperature display TD ₁ , temperature setting device TV, heating time timer T ₁ , reservation timer T ₂ , heating indicator lamp L ₁ , reservation indicator lamp L ₂ , and amplifier power switch S are located. In addition, as shown in FIG. 5, on the inner panel 31, an interior light 35,
An indoor temperature indicator TD ₂ , three types of display lamps LD ₁ , LD ₂ , LD ₃ for displaying the elapsed time, a switch CS for turning on/off the elapsed time display, and a temperature sensor TS are located.

Both indoor temperature indicators TD ₁ and TD ₂ above are temperature sensors.
It displays the indoor temperature detected by the TS, and both are configured as light emitting diode arrays. Also, among the three types of display lamps LD ₁ , LD ₂ , and LD ₃ for displaying elapsed time, the display lamp LD ₁ consisting of four rectangular light emitting diodes in the figure is
The display lamp LD ₂ , which is composed of four round light emitting diodes in the figure, displays the minute units, and the display lamp LD ₃ , which is a light emitting diode, blinks every second. This allows display in seconds.

Here, indicator lamp LD ₁ and indicator lamp LD ₂
By setting four of each and lighting only one of each according to the elapsed time, it is possible to display up to 24 minutes in 1-minute increments. For example, 12 minutes is displayed by lighting the 10-minute display lamp LD ₁ and the 2-minute display lamp LD ₂ , as shown in the figure. By blinking the display lamp LD ₃ every second, it is made clear to the user that the time elapsed in seconds and the elapsed time display are operating normally.

Now, as shown in FIG. 1, the control circuit C includes a reservation timer T ₂ , a heating time timer T ₁ , a temperature sensor TS, an indoor temperature indicator TD ₁₉ TD ₂ , and a display lamp LD ₁ for displaying elapsed time. , LD ₂ , LD ₃ , reservation indicator lamp L ₂ , heating indicator lamp L ₁ , etc., are connected to the heaters H ₁ , H ₂ for raising the room temperature inside the main body 1. is connected to the power supply via the reservation timer _T2 , the heating time timer _T1 , and a relay Ry controlled by the operation control circuit C. Further, the interior light 35 is connected to the power source via a reservation timer _T2 .

However, in this electric sauna, when the power switch SW is turned on, the indoor light 35 is turned on.After this, the desired temperature is set on the temperature setting device TV, and the desired energization is applied to the heating time timer _T1 . Once the time is set, the normally open load contact built into the heating time timer _T1 closes and the heater _H1 ,
When energization of _H2 is started and the built-in auxiliary contact of the heating time timer _T1 is closed, the operation control circuit C lights up the heating indicator lamp _LD1 . Then, by comparing the temperature sensor TS output and the input from the temperature setting device TV, the operation of heaters H ₁ and H ₂ is controlled through the relay RY, and the indoor temperature inside the main body 1 is set to the temperature set by the temperature setting device TV. This temperature is displayed in the form of a bar graph by temperature indicators TD ₁ and TD ₂ .

A temperature display TD ₂ is installed on the inside of the main body 1 to inform the user of the indoor temperature while taking a bath.A temperature display TD ₁ is also installed on the outside of the main body 1 because the indoor temperature is This is so that the user can know before taking a bath whether or not the temperature has reached the appropriate temperature for the bath.

The elapsed time during this sauna bath can be known by turning on the switch CS installed on the inner surface of the main body 1 and displaying the elapsed time using three display lamps LD ₁ , LD ₂ , and LD ₃ . can. Note that this time elapsed display has no relation to the time set in the heating time timer _T1 , and is only a function of the switch CS.
Shows the elapsed time from the time you entered.

When the time set in the heating time timer T ₁ has elapsed, the load contacts and auxiliary contacts built into the heating time timer T ₁ open, the power to the heater H ₁₉ H ₂ is cut off, and the heating indicator lamp L ₁ turns off. goes out.

When the operation start time of heating time timer T ₁ is set in reservation timer T ₂ , at that point the normally closed load contact built into reservation timer T ₂ opens and the built-in auxiliary contact closes. , even if the heating time timer T ₁ is set, the heater H ₁ ,
No power is supplied to H ₂ or the interior light 35, and the reservation indicator lamp L ₂ lights up. Then, at the time set by reservation timer T ₂ , the built-in load contact of reservation timer T ₂ closes and the built-in auxiliary contact opens.
The reservation indicator lamp L ₂ is turned off, the interior light 35 and the heating indicator lamp L ₁ are turned on, and the heaters H ₁ and H ₂ are energized through the heating time timer T ₁ . From then on, as in the previous case, heaters H ₁ and H ₂
energization is under the control of the operation control circuit C,
It operates only for the time set by heating time timer _T1 .

The reservation timer T ₂ here may be of the type that has a built-in clock and literally sets the activation time of the heating time timer T ₁ as the time, but the heating time timer It may also be of the type that sets the activation time of _T1 . In any case, by setting the heating time timer _T1 to operate a little before the desired sauna time, you can take a sauna bath at the desired time without waiting for the preheating time. . In addition, since power is supplied to the heaters H ₁ and H ₂ only through the heating time timer T ₁ , even if you are unable to take a bath at the set time, the time set by the heating time timer T ₁ will still elapse. If this is done, the power supply to the heaters H ₁ and H ₂ will be cut off, so it is safe.

Note that even if the reservation timer _T2 is set without setting the heating time timer _T1 , the operation control circuit C does not turn on the reservation indicator lamp _L2 and prompts the setting for the heating time timer _T1 . It is set as. FIG. 2 shows a schematic flow of the above operation. The temperature indicators TD ₁ and TD ₂ are also turned on and off at the same timing as the heating indicator lamp L ₁ .

The heater H ₂ placed at the back under the seat 10 is
This was installed in consideration of the fact that the temperature at your feet will not rise very high if you use just the heater _H1 , and it reduces the difference in indoor temperature above and below, and at the same time shortens the time it takes for the indoor temperature to reach the desired temperature.

The amplifier box A and speaker SP are provided so that the output terminal of a radio or tape recorder can be connected to the input terminal Ain of the amplifier box A so that the user can enjoy music etc. while taking a bath.
Amplifier box A receives power from power supply circuit D for operation control circuit C. Although the amplifier power switch S is provided on the outer surface of the main body 1, it may also be provided on the indoor side.

By the way, as mentioned above, the control box 3 is provided in the frame part 15, and since the frame part 15 is designed to protrude toward the indoor side in order to save space on the main body 1, the control box 3 is installed inside the sauna room. Temperature is becoming more likely to affect electronic components through the panel 31. For this purpose, as shown in Figure 4,
A ventilation hole 17 is provided on the lower surface of the frame part 15 and on the outside of the doorstop 16, and a ventilation hole 18 is also provided above the frame part 15, so that outside air flows into the frame part 15 from the ventilation hole 17, and ventilation Cooling is achieved by allowing the liquid to exit from the opening 18. A cover 19 that protrudes diagonally from the top surface of the main body 1 and covers the ventilation hole 18 at intervals prevents the ventilation hole 18 from being blocked even if the user places something on the top surface of the main body 1. It is for the purpose of

〔Effect of the invention〕

As described above, in the present invention, a heating time timer is used to set the time for energizing the heat source, and a heating time timer is used to set the operation start time of the heating time timer, which is the time to start energizing the heat source. Since it is equipped with a reservation timer to be activated, it is possible to start energizing the heat source according to the time when the user wants to take a bath.For this purpose, by setting the reservation timer, It is a device that allows you to take a bath without having a preheating time at the time, and you can take a bath first thing in the morning or immediately after returning home. Moreover, this reservation timer is set before the heating time timer starts operating. The time is set, and since the power is turned on to the heat source only through the heating time timer, even if the user forgets that they have made a reservation, the power will be turned on to the heat source after the specified time. It is safe because the current is cut off.
