Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a kotatsu in which an operating section of a control circuit for controlling power, temperature, etc. is disposed on a table board, and the operating section and the control circuit are connected wirelessly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the Yagura Kotatsu of the present invention will be described below with reference to the drawings.

The Yagura Kotatsu of the present invention is constructed as shown in Figs. and 4B is electric power,
These are operation units for controlling the temperature and the like, and in this case, they are provided at two locations on opposite sides of the table board 1. 5
A and 5B are the knobs of the operating parts 4A and 4B, 6 is a release that connects the operating parts 4A and 4B, and 7 is a variable part that changes the temperature setting by sliding the knob 5A or 5B in the left and right direction. be. 9 is a control circuit, 10A and 10B are electrode plates arranged on the Yagura Kotatsu body 2, and the table plate 1
The electrode plates 10A and 10 of the Yagura Kotatsu main body 2 are paired with the electrode plates 11A and 11B arranged in the kotatsu body 2, respectively.
B and the electrode plates 11A and 11B of the table plate 1 are coupled with a capacitor to form a means for transmitting electric signals between the variable part 7 of the table plate 1 and the control circuit 9 of the kotatsu. Reference numeral 12 denotes a heater which is controlled by the control circuit 9 to have a predetermined amount of heat generated.

Next, the operating state of the Yagura Kotatsu constructed as described above will be explained.

The signal from the control circuit 9 is transmitted to the variable part 7 via the stray capacitance C _A between the electrode plates 10A and 11A, and the variable part 7 is varied by sliding the knob 5A of the operating part 4A or the knob 5B of the operating part 4B. An electric signal corresponding to the amount of change or the position of change is fed back to the control circuit 9 via the stray capacitance C _B between the electrode plates 11B and 10B. The control circuit 9 then controls the energization of the heater 12 of the kotatsu in response to the feedback signal (or in response to the signal if it has a temperature sensor).

In the above case, since the knob 5A of the operating section 4A or the knob 5B of the operating section 4B is mechanically interlocked by the release 6, which knob 5A, 5
The variable portion 7 can also be made variable by sliding B.

Since the Yagura Kotatsu of the present invention has the above-described configuration, it is possible to control the power, temperature, etc. inside the Kotatsu by operating the operation parts provided at multiple locations at different positions on the side surface of the table board. The operating section can be operated extremely easily and reliably from any location on the board, making it convenient to use.Moreover, since the operating section is provided at multiple locations at different positions on the side of the table board, items can be placed on the table board. The control panel does not get in the way even when
Moreover, since only the operating section for operating the control circuit is provided on the table board, the space for the operating section on the table board is made up of variable resistors, monostable multivibrators, and batteries that power them. It is extremely small compared to a device that is provided with a control signal generating means, 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. Furthermore, since the battery that serves as the power source for the table board can be eliminated, maintenance and inspection of the battery can be eliminated, and the stray capacitance between the table board holding part and the control circuit of the Yagura Kotatsu body can be reduced by using electrode plates. Since the wireless connection is made via the electric kotatsu table, the temperature control signal generated by the temperature control signal generation means on the table of the electric kotatsu is transmitted to the temperature control signal detection means provided on the frame base of the electric kotatsu via a medium consisting of a coil and an iron core. Compared to those that use the Yagura Kotatsu, it is less affected by the noise that occurs when controlling the temperature of equipment around the Yagura Kotatsu, such as electric carpet heating equipment, and the control of the Yagura Kotatsu itself is more reliable with the operation part on the table board. The circuit can be controlled, and the space on the table plate where the electrode plate is provided can be small, and the electrode plate can be easily provided at a desired position on the table plate.
