Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a heater that performs pair heating by using an electric carpet and an electric kotatsu in combination, and achieves a particularly efficient heating effect.

[Prior Art] Conventionally, an electric kotatsu is placed on top of an electric carpet, and the two are used together to perform pair heating.

[Problem that the invention attempts to solve]

However, in the past, even when they were used together, the temperature had to be controlled by each controller, and efficient combined operation of an electric carpet and an electric kotatsu was not possible.

Therefore, this invention was made in view of the above-mentioned problems, and provides a heater that can efficiently operate both an electric carpet and an electric kotatsu by controlling the temperature of both using a pair heating controller. It is something to do.

[Means for solving problems]

The heater according to this invention is equipped with a sensor wire at a predetermined location on the electric carpet to detect the heat generation of the carpet, and a radiant wire on the surface of the carpet to detect the radiant heat temperature of the electric kotatsu placed on the carpet. A heat detection sensor is provided, and the electric carpet is provided with a first sensor that controls the temperature of the electric carpet according to a detection signal from the radiant heat detection sensor.
a controller, a second controller that controls the temperature of the electric kotatsu according to a detection signal from the sensor wire, and operates simultaneously with one of the first or second controller, or both the first and second controllers. It consists of a setting circuit that allows the electric carpet or electric kotatsu to be used alone,
and a pair heating controller section that allows selection of combination use of both.

[Effect]

According to the pair heating controller of this invention, the temperature of the electric carpet can be controlled according to the heat generation temperature of the electric carpet, and the temperature of the electric kotatsu can be controlled according to the radiant heat of the electric kotatsu detected on the electric carpet side. Moreover, since the temperature can be controlled for both at the same time, it is easy to switch the control when controlling either the electric carpet or the electric kotatsu, or both in combination.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of the electric circuit in FIG. 2, which shows a schematic diagram when an electric carpet and an electric kotatsu are used together. In both figures, 1 is an electric carpet, 2 is an electric kotatsu, and 3 is an electric carpet 1.
A pair heating controller 5 is provided on the central surface of the electric carpet 1 and is equipped with an outlet exclusively for the kotatsu, and is connectable to the electric kotatsu controller 4; The pair heating controller 3 can select whether to use the electric carpet 1 or the electric kotatsu 2 alone or in combination.
and a setting circuit 3a that can set the heating temperature, input of the set temperature, and heater wire 1 of the electric carpet 1.
a first controller 3b that controls the temperature of the heater wire 1a based on a detection signal from the sensor wire 1b that detects the temperature of the electric kotatsu 2; The second controller 3c controls the temperature of the kotatsu heater 2a based on the detection signal from the heat detection sensor 5.

The radiant heat detection sensor 5 is provided on the central surface of the electric carpet 1 to detect the radiant heat temperature of the electric kotatsu 2 placed thereon. 1
The temperature is detected by adding the radiant heat temperature of the kotatsu at the center floor of electric kotatsu 2 to the surface temperature of electric kotatsu 2.
The temperature is -10° lower than the guaranteed temperature.

Further, when the setting circuit 3a selects the mote for single use of the electric carpet 1 or the electric kotatsu 2, the respective controllers 3b or 3
Only the setting circuit 3 is made to operate, especially the setting circuit 3.
When the single use mode of the electric kotatsu 2 is selected by c, the second controller 3c operates, and the mode selection signal causes the original electric kotatsu controller 4 to be in an input/output short-circuited state.

Therefore, according to the above configuration, the temperature of both the electric carpet 1 and the electric kotatsu 2 can be controlled by the pair heating controller 3, and the setting circuit 3a
This makes it possible to switch between modes for single use and combined use, allowing for efficient combined operation.

[Effect of idea]

As described above, according to this invention, it is possible to perform mode switching and temperature control for both electric carpet and electric kotatsu for single or combined use using a pair heating controller. This has the advantage that it can be easily performed on the electric carpet side.
