Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a canopy kotatsu in which an operating section of a control device for controlling power, temperature, etc. is provided on a table board, and particularly to a canopy kotatsu that is easy to use and has a simple structure.

Conventional control methods for power, temperature, etc. of Yagura Kotatsu are broadly divided into two types: thermostatic type and electronically controlled type. In the thermostatic type, the temperature is controlled by a variable thermostat attached to the Yagura Kotatsu body. In order to do this, you have to put your hand inside the kotatsu futon and set it at the appropriate position each time, which makes it very inconvenient to use.Also, the electronic control type has to be separated from the Yagura Kotatsu body as a remote control and connected with a cord. The setting position of the temperature control can be easily checked and set, but the remote control itself is placed on the floor and gets in the way, and there are many wires including load lines and signal lines from the main body of the Yagura Kotatsu. Since the core cord is connected to the remote control, the configuration is complicated and the cost is relatively high.

The present invention relates to a kotatsu that eliminates the above-mentioned drawbacks.

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. 1 and 2.
In the figure, 1 is the main body of the kotatsu, 2 is the control unit attached to the main body of the kotatsu, 3 is the power cord, 4 is a load cord (multi-conductor cord) connecting the control unit 2 and the heater 5, and 5 is the main body of the kotatsu 1. It is a heater (electric heating part). 6 is the leg of the kotatsu main body 1; 7A and 7B are electrode plates attached to the kotatsu main body 1; 8 is a table plate that is usually placed on the kotatsu main body 1 via a kotatsu futon;
Electrodes 9A and 9B are attached to the table plate so as to face the electrode plates 7A and 7B of the Yagura Kotatsu body 1, respectively, and are paired with the electrode plates 7A and 7B of the Yagura Kotatsu body 1, respectively, for transmitting (sending and receiving) electrical signals. A board 10 is an operating section for adjusting power, temperature, etc., which is provided on the table board 8.
0, the operation signal of the operation unit 10 is transmitted to the control unit 2 via the electrode plates 9A, 9B of the table plate 8 and the electrode plates 7A, 7B of the Yagura Kotatsu main body 1.
The controller 2 energizes the heater 5,
Temperature etc. are controlled.

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

A signal from the control section 2 of the Yagura Kotatsu main body 1 is transmitted to the operation section 10 of the table board 8 via the stray capacitance C _A between the electrode plate 7A of the Yagura Kotatsu main body 1 and the electrode plate 9A of the table board 8. A signal corresponding to the operation (position) is transmitted to the control unit 2 of the Yagura Kotatsu body 1 via the stray capacitance C _B between the electrode plate 9B of the table board 8 and the electrode plate 7B of the Yagura Kotatsu body 1.
will be returned to. Therefore, the control section 2 controls the energization of the heater (electric heating section) 5 of the kotatsu main body 1 in response to the feedback signal (or in response to the signal if it has a temperature sensor).

As described above, the power, temperature, etc. of the Yagura Kotatsu are controlled.

Since the Yagura Kotatsu of the present invention has the above-mentioned configuration, it is easy to use, and since the operation section for variable operation of the control section is provided on the table board placed on the Yagura Kotatsu body, the space for the operation section on the table board is saved. There is a variable resistance on the table board,
Compared to monostable multivibrators, which are equipped with temperature control signal generation means formed from batteries, etc., which serve as their power source, they are extremely small, and there is no need to secure special space on the table board for installing the operating section. Therefore, the operating section can be easily provided at a desired position on the table board, and furthermore, since the battery that serves as a power source for the table board can be eliminated, maintenance and inspection of the battery can be made unnecessary. Then, the operation section on the table board, which only allows variable operation of the control section, and the control section on the main body of the Yagura Kotatsu were connected wirelessly by capacitor coupling via stray capacitance.
Compared to the one in which the temperature control signal generated by the temperature control signal generation means of the electric kotatsu table 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, It 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 body can be controlled more reliably using the operating section on the table board. At the same time, the space on the table plate in which the electrode plate for capacitor coupling is provided can be small, and it can be easily provided at a desired position on the table plate. In addition, since the electrode plates are placed facing the Yagura Kotatsu body and the table board, the spacing between the electrode plates is extremely short, and interference from external noise can be almost eliminated, and capacitor coupling ensures reliable operation. The control circuit can be controlled.
