Abstract

PURPOSE:To enable the fine adjustment of warming and power consumption by a construction wherein shielding bodies arranged in front of a radiating body are moved appropriately to enable the arbitrary setting of an area of radiation. CONSTITUTION:When a radiating body 6, which is prepared by using a resistance heating element 5 having a positive resistance temperature coefficient as indicated by a curve, is covered at about 50% with sielding bodies 7a and 7b, the temperature of the covered parts of the radiating body 6 becomes high (about 100 deg.C), since the radiation is interrupted, and simultaneously the resistance values of these parts increase, which results in the sharp reduction of a consumped power. In the remaining 50-percent part of the radiating body which is not covered with the shielding bodies, the same radiation density is maintained, and the surface temperature thereof is stabilized at about 80 deg.C. By moving the shielding bodies 7a and 7b appropriately in this way, a required quantity of radiation is taken out of a part wherefrom the warmth is desired to take out, and thus warming can be performed effectively. In addition, an energy can be further saved by forming the surfaces of the shielding bodies 7a and 7b on the radiating body side to be specular and the surfaces thereof on the other side to be colored black.

していた。(Constitution of Conventional Example and Problems thereof) Conventionally, for example, heating adjustment of a radiant panel heater has been performed using a circuit configuration shown in FIG. In Fig. 1, reference numerals 1 and 2 are resistance heating elements, and by connecting one or both of resistance heating elements 1 and 2 to a power source 4 using a switch 3, the temperature of the radiator is adjusted and heating is controlled. Ta. However, in this case, although the amount of heat generated can be adjusted by switching the switch 3, since it is a two-point switch, it is difficult to finely adjust the heating temperature. Although it is possible to select an appropriate temperature by increasing the number of resistive heating elements, such a switching method not only causes unevenness in the surface temperature of the radiator due to the arrangement of the resistive heating elements. , productivity will also decrease. In actual use, non-uniformity in the surface temperature of the radiator may be solved as long as it is possible to match the portion where the heat is desired to be collected and the high temperature portion of the radiator surface, but this is extremely difficult from a structural standpoint. When using a thermostat to adjust the surface temperature of a radiator, in order to ensure high reliability and high safety when using a large current like a panel heater, it is necessary to adjust the thermostat's temperature when it is on and when it is off. The difference from the temperature must be set to about 20 degrees or more, and therefore, although it is good to use a thermostat to prevent excessive temperature rise, it is not suitable for adjusting the temperature on the surface of the radiator. Further, although it is possible to control using a thermistor, a relay, etc., the circuit structure is complex and has the disadvantage of reducing productivity.

なる。Figure 3 shows the resistance-temperature characteristics of the PTC heating element 5 used in this example, with the horizontal axis representing temperature and the vertical axis representing 20°C.
The resistance ratio (RA2o) is taken based on the resistance value of . When the PTC heating element 5 having such characteristics is used, when the shields 7a and 7b are moved and completely removed from the front surface of the radiator 6, the surface temperature of the radiator 6 is stabilized at about 80°C. Also, a part of the radiation surface of the radiator 6 is shielded by a shielding body 7a.
, 7b, the radiation from the covered portion almost disappears, the surface temperature of the radiator at that portion rises by about 100° C., the resistance value increases, and the power consumption becomes extremely small.

When electricity is applied to a panel heater stabilized in becomes stable when it drops to about 500W. Furthermore, when the radiator 6 is covered by about 50% with the shields 7a and 7b, the covered part of the radiator becomes high temperature (approximately 100 degrees Celsius) because it is blocked from radiation, and the power consumption of this part is the lowest. Approximately 1 during stable operation according to the PTC characteristics shown in Figure 3.
15, the total power consumption in this case is about 300W. On the other hand, the remaining 50% of the radiators not covered by the shield maintain the same radiation density.

きる。As described above, in this embodiment, by appropriately moving the shielding bodies 7a, 7t), the required amount of radiation can be taken out only in the area to be heated, thereby effectively heating the area. Furthermore, if the surfaces of the shielding bodies 7a and 7b on the radiator side are mirror-finished, the shielded radiant heat is totally reflected and returned to the radiator 6, which improves the shielding efficiency and saves energy. 1. The radiation system of the shields 7a and 7b can be improved by making the opposite sides black so that some of the heat lost in the shielding can be reused as radiation.

A configuration in which a shielding body is arranged may also be used.

一般に、輻射量は輻射体温度の４乗に比例する。Generally, the amount of radiation is proportional to the fourth power of the temperature of the radiator.

効果的な採暖調節を可能にするものである。For this reason, adjust the power consumption, for example 7? ! If the power consumption is halved, less than half the amount of radiation can be obtained. Furthermore, when the radiation density decreases, radiation may not be felt at all in many cases, depending on the room temperature and usage conditions. From this point of view, the configuration according to the present invention adjusts heating by the area of the radiator as described above, so the radiation density is almost the same even if the area is small, making it very comfortable and effective heating. It allows for adjustment.
