Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dowel kotatsu in which a control circuit for power, temperature, etc. is provided on the main body of the dowel kotatsu, and an operating section of the control circuit is provided on a table board.

Hereinafter, one embodiment of the Yagura Kotatsu of the present invention will be described with reference to FIGS. 1 to 3.

In Figures 1 to 3, 1 is a table board;
2A and 2B are electrode plates provided at predetermined positions on the table board 1; 3 is an operating section provided on the side surface of the table board 1; 4 is the main body of the kotatsu; and 5 is provided on the top plate 6 of the kotatsu main body 4. Electric heating part (heater),
Reference numeral 7 designates the legs of the canopy kotatsu body 4; 8 denotes a heat insulator such as a futon that covers the canopy kotatsu body 4 and keeps the inside of the canopy kotatsu warm; 9A and 9B designate electrode plates provided on the canopy kotatsu body 4; They are paired with the electrode plates 2A and 2B of 1, respectively, and the stray capacitances C _A and _CB generated between the electrode plates 9A and 2A and 2B and 9B perform capacitor coupling, and wireless electrical signal transmission is performed. 1
Reference numeral 0 denotes a variable section linked to the operation section 3 of the table plate 1, and 11 a control circuit for temperature, power, etc., which controls the supply of electricity to the heater 5 by the variable operation of the variable section 10. Control circuit mounting part 12
The control circuit 11 is provided integrally with at least one electrode plate 9A or 9B of the electrode plates 9A and 9B provided on the Yagura Kotatsu main body 4, and the control circuit 11 is provided with a temperature sensing sensor. If the heater 5 is provided in the kotatsu main body 4, the energization of the heater 5 is also controlled by the signal from the temperature sensor. 13 is a cord connecting between the control circuit 11 and the heater 5.

Next, to explain the operating state of the Yagura Kotatsu configured as described above, a signal from the control circuit 11 is transmitted to the variable part 10 via the stray capacitance C _A between the electrode plates 9A and 2A, and the variable part 10 is Operation unit 3
A signal corresponding to the variable amount (change amount) or variable position (change position) of the variable portion 10 that is varied by the operation of is sent to the control circuit via the stray capacitance C _B between the electrode plate 2B and the electrode plate 9B. He will be returned on the 11th. Therefore, the control circuit 11 controls the energization of the heater 5 of the kotatsu main body 4 in response to the feedback signal to maintain the temperature at a predetermined temperature. At this time, if a temperature sensor is provided, energization of the heater 5 is controlled in response to a signal from the sensor to maintain a predetermined temperature.

As described above, in the Yagura Kotatsu of the present invention, only the operating section of the control circuit is provided on the table board, so the space for the operating section on the table board is used for variable resistors, monostable multivibrators, batteries that power them, etc. It is extremely small compared to a device that is provided with a temperature control signal generating means formed by a method, and there is no need to secure a special space for installing the operating section on the table board, and the operating section can be easily installed at a desired position on the table board. In addition, since the battery used as a power source on the table board can be eliminated, maintenance and inspection of the battery can be eliminated, and furthermore, a capacitor can be connected between the operation unit and the control circuit via stray capacitance. Since the electric gotatsu table is connected wirelessly, the temperature control signal generated by the temperature control signal generation means on the table of the electric gotatsu is transmitted to the temperature control signal detection means provided on the frame base of the electric gotatsu via a medium consisting of a coil and an iron core. The control circuit of the Yagura Kotatsu itself is less affected by the noise that occurs when controlling the temperature of surrounding equipment such as electric carpet heating equipment, and the control circuit of the Yagura Kotatsu itself is more reliable than that of the Yagura Kotatsu. In addition, the space required on the table plate for providing the electrode plate for capacitor coupling can be small, and it can be easily provided at a desired position on the table plate. In addition, the control circuit and at least one of the electrode plates on the kotatsu body side are integrally attached to the kotatsu body using the control circuit attachment part, making it extremely easy to attach the electrode plate to the kotatsu body and simplifying the manufacturing process. The structure can be simplified, and therefore the number of members for mounting the electrode plate can be reduced, making it possible to reduce the cost.
