Abstract

PURPOSE:To realize comfortable heating, by detecting the temperature of at least one of plural heating apparatuses, and alternately executing electric conduction to plural heating apparatuses in accordance with the temperature. CONSTITUTION:On an electric carpet 2, an electric ''kotatsu'' (food warmer with a quilt over it) 8 is placed, and a cord 20 of the ''kotatsu'' 8 is connected to the carpet 2. When the temperature of an electric heating part 9 of the ''kotatsu'' 8 is lower than a prescribed value, and a thermostat 10 is closed, a relay 4 is opened, electric conduction to a heater 3 of the carpet 2 is stopped, and heating by only the ''kotatsu'' 8 is executed. When the temperature of the ''kotatsu'' 8 becomes a prescribed value, the thermostat 10 is opened, electric conduction to a heater 11 of the ''kotatsu'' 8 is stopped, the relay 4 is closed, and the heater 3 of the carpet 2 is conducted. When the temperature of the electric heating part 9 of the ''kotatsu'' 8 becomes lower than a prescribed value, the thermostat 10 is closed again, electric conduction to the heater 11 is started, and electric conduction to the heater 3 is stopped. In this way, comfortable heating is executed alternately from the upper and lower sides.

The heater 11 of the electric roof kotatsu 8, which is disposed in the electric heating section 9 of the electric roof kotatsu 8, is connected between the heater 11 and the heating section c.

In the above configuration, the electric carpet 2 is provided with a heater 3 inside so as to be located on the entire surface of the electric carpet body 12 as shown in FIGS. 2 and 3. A connection part for connecting a heater 3, etc. to one end corner, and a relay 4. A storage case (joint box) 13 containing the connector 5 and the like is disposed, and one end of the connection cord 14 is connected to the connection part of the storage case 13, and a controller (controller) for controlling the electric carpet 2 is connected to the other end of the connection cord 14. controller) 1
5 is connected to the controller 15, and the other end of a power cord 17 having a connector (power plug) 16 connected to an AC power source 1 is connected to the controller 15 at one end. As shown in the figures and FIG. 3, a heater 11 consisting of an infrared lamp, a semiconductor heater, etc. is mounted on the lower surface of the upper plate 19 of the Yagura Kotatsu main body 18. An electric heating section 9 including a thermostat 10 for detecting heat generated by the heater IHC is attached, and a heater 11 of the electric heating section 9 is installed. Connect the other end of an onion connection cord 20 having a connector 6 connected to the connector 5 of the electric carpet body 12 at one end to a thermostand 10 or the like, cover the Yagura Kotatsu body 18 with a heat retainer 21,
The heater 3 of the electric carpet 2 is configured to be used by placing a top plate 22 on top of the heat insulator 21, and the heater 3 of the electric carpet 2 can be used alone between the electric carpet 2 and the main body 18 of the electric bed. The temperature of the space 23 formed does not rise to a predetermined temperature, but rises above the predetermined temperature by the heater 11 of the electric roof kotatsu 8.Next, the temperature control of the present invention configured as described above To explain the usage condition of the device, an electric canopy kotatsu 8 is placed on a predetermined position on the electric carpet 2, and the electric canopy kotatsu 8 is
Connect the connecting body 6 of the connecting cord 20 to the connector 5 of the storage case 13 of the electric carpet 2 and the first connecting piece 6 of the connecting body 6.
