DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heater, and particularly to a control means thereof.

[Conventional technology]

Conventionally, hot air heating systems that heat indoor air have the advantage of allowing people to live their lives without worrying about heating because the entire room is heated. However, in this case, warm air rises to the top of the room, creating a temperature difference between the top and bottom of the room. By using such hot air heating in combination with floor heating, you can ensure the temperature of your feet.
It is possible to eliminate the temperature difference between the top and bottom of the room. In addition, in this case, since the heating method uses radiation, it is possible to obtain a comfortable feeling even if the room temperature is lower than in the case of heating only with the hot air heater, and it is possible to obtain a comfortable thermal environment where the head is cold and the feet are warm.

The aforementioned control line will now be explained. A person's thermal sensation is determined by the relationship between the amount of heat produced by the human body and the amount of heat released outside the body. Generally, when there is a balance between the amount of heat produced and the amount of heat released, people feel comfortable, neither hot nor cold. In heating, a sense of comfort can be achieved by reducing the amount of heat radiated to the outside of the body. As the indoor air temperature rises, the amount of heat radiated from a person's body decreases, allowing occupants to feel comfortable even if the floor temperature is low. Similarly, if the floor temperature is high, you can feel comfortable without raising the room temperature too high. In this way, people's sensations are determined by the relationship between floor temperature and room temperature. As shown in FIG. 9, the environment of the upper limit temperature Tab of the room temperature and the corresponding lower limit temperature Tfl of the bed temperature, the lower limit temperature Tal of the room temperature and the corresponding upper limit temperature Tfh of the bed temperature

The room temperature Tan is detected by the room temperature detector 4 at O3. Step F204 is an operation as a target temperature calculation means,
As shown in FIG. 9, the room temperature target temperature Tas is determined from the received floor temperature Tfn using the control line CL. In step F2O3, if the room temperature Tan does not exceed the target temperature Tas (for example, Tan1), the warm air heater 1 is operated by the heater control device 10 (Fig. 7) in step F206, and in step F2O3, the room temperature Tan is set to the target temperature Tas.
