JPS5811346A - Foot warmer with erected wooden frame - Google Patents

Abstract

PURPOSE:To facilitate putting of a quilt and a table top board thereon by a method wherein an operating unit, operating a control circuit controlling a heating body, is provided on the table board putting on the main frame of the foot warmer in the wooden frame and the operating unit on the table board and the control circuit are connected through capacitors. CONSTITUTION:When an user operates the operating unit 4 to control the temperature of theheating body 2 through an electric conduction control or a temperature control, an oscillation signal, outputted from an oscillator 11, is varied by the operating unit 4 through a capacitor element CA and is detected by a detecting unit 12 through the capacitor element CB. Then, it is amplified by an amplifier 13 is inputted into a control unit 14 to control the electric conduction of the heating body 2.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Yagura kotatsu in which a control circuit for controlling the energization of the heating element of the Yagura kotatsu body can be operated wirelessly using an operating section provided on a table board placed on the Yagura kotatsu body. It is.

Conventional Yagura Kotatsu, for example, a Yagura Kotatsu in which a control circuit for controlling the energization of the heating element of the Yagura Kotatsu body is operated by an operation part provided on a table board placed on the Yagura Kotatsu body, is a Yagura Kotatsu that is operated by an operation part provided on the table board and the above-mentioned control circuit. It is constructed by connecting the control circuit that controls the power supply to the heating element of the Yagura Kotatsu body with a lead wire (cord E), so when using the Kotatsu Futon on the Yagura Kotatsu body, the lead wire is Moreover, there was a drawback that the table board could not be placed in any direction because the lead wires were in the way.

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

An embodiment of Hongenbo's Yagura Kotatsu will be described below with reference to the drawings.

As shown in FIG. 1, the Yagura Kotatsu of the present invention is provided with a control circuit (control device) 8 for controlling the heating element load and electricity supply to the heating element 2 in the Yagura Kotatsu main body 1, and an operation section for operating the control circuit 3. 4 is removably installed on a table plate 6 placed on the kotatsu main body 1 via a kotatsu futon 5, and the operating section 4 of the table plate 6 and the control circuit 8 of the kotatsu main body 1 are connected wirelessly by capacitor coupling. It was constructed as follows.

In Fig. 1, 7 is a power plug 8 connected to the power supply.
A power cord with a

Fig. 2 is a block diagram of the control system of the Yagura Kotatsu shown in Fig. 1, where 1 is the main body of the Yagura Kotatsu, 2 is the heating element, 3 is the control circuit, and 4 is the variable function such as a variable capacitor, variable resistor, and variable coil. Operation unit, 6 is a table board, 9A and 9B
are the electrode plates, IOA and IOB arranged on the table plate 6.
is an electrode plate disposed on the Yagura Kotatsu main body 1, and the stray capacitance between the electrode plate 10A and the above electrode plate 9A (, A, and the stray capacitance CB between the above electrode plate 10B and the above electrode plate 9B are capacitor components), and the above control is performed. Ol which connects the circuit 3 and the above-mentioned operation part 4 wirelessly (relay) by capacitor coupling.
1 is an oscillator, 12 is a detection section, +1 is an amplification section, and 14 is a control section.

In the Yagura Kotatsu of the present invention configured as described above, when a user (omitted) operates the operation unit 4 to control the temperature of the heating element 2 by energization rate control or temperature control, the oscillator 11 generates an oscillation signal. Capacitor component CA (electrode 9A
- electrode+OA capacitance t), is varied by the operating section 4, and is detected by the detecting section 12 via the capacitor component CB (electrode 9B-electrode 10B capacitance). Then, it is amplified by the amplifying section 1B, and the heating element 2 is
energization is controlled.

Since the Yagura Kotatsu of the present invention has the above-mentioned configuration,
The futon can be placed on the Yagurakotatsu body very easily, and the table board can be placed in any direction.
