い。When a large amount of heat is stored, the heater main body 12 can perform indoor heating by natural heat radiation by the radiant heat from the front panel 20A of the housing 20. Such heating by radiant heat uniformly heats the entire room, and thus forms an extremely comfortable heating space. In order to efficiently perform indoor heating by such natural heat radiation, the heat insulating material 28 that is close to the heat storage body 26 at least on the front panel 20A side is formed of a heat insulating material having a property of increasing thermal conductivity at high temperatures. It is preferable that the outer heat insulating plate 30 is formed of a heat insulating material having a property that the thermal conductivity hardly increases even at a high temperature. On the contrary, on the back surface or bottom surface side that does not contribute to such radiant heating, the heat insulating material 28 close to the heat storage body 26 is provided.
In order to prevent wasteful natural heat dissipation, it is preferable that the heat insulating material has a property that the thermal conductivity does not increase at high temperature.

することができる。When the heat insulating material 28 and the heat insulating plate 30 are made of a heat insulating material having such a property, when the heat storage body 26 is at a high temperature close to 700 ° C., the surface temperature of the front panel 20A is about 80 ° C. This front panel 20A
With the radiant heat of 1, even when the outside air temperature is low such as in the morning in winter, an extremely strong heating effect can be obtained. Then, when strong heating is not required, such as during the daytime, the temperature inside the heat storage chamber 22 decreases due to the temperature drop of the heat storage body 26 due to the stop of the power supply to the electric heater 32 and the natural heat dissipation, so the heat storage body 26 is reduced. It is possible to increase the heat insulating effect of the heat insulating material 28 adjacent to the heat insulating material 28, thereby reducing the natural heat radiation from the front panel 20A and maintaining the heat storage amount in the heat storage chamber 22.

And an auxiliary sensor 46. The heat storage body temperature sensor 40 detects the temperature of the heat storage body 26, and the auxiliary sensor 46 is heated by a control heater 64 described later, and acts to increase the detected value of the heat storage body temperature sensor 40 in accordance with the outside air temperature. . This allows the main controller 4
When the outside air temperature rises, No. 4 operates the electric switch 48 even when the temperature of the heat storage body 26 is low and the amount of stored heat is small, and opens the main power line I that supplies power to the electric heater 32. Therefore, the heat storage amount of the heat storage body 26 when the outside air temperature is high becomes smaller than the heat storage amount when the outside air temperature is low.
The heat storage amount when the main controller 44 opens this main power line I is set by the manual adjustment dial shown by reference character B in FIG. It can be set to any size within the range. The lamp 32L displays the open / closed state of the main power line I.

The output of the auxiliary controller 68 required to do so is shown. The maximum output of the auxiliary controller 68 is set to 80% because the heat storage body 26 has a temperature at least equal to room temperature and the heat storage body temperature sensor 40 corresponds to this temperature even when the outside air temperature does not require heat storage. This is because the temperature signal is output to the main controller 44.

The dial has a maximum outside air temperature setting range of 12 to 20 ° C. when heat storage is stopped. For example, when the minimum outside air temperature is set to -12 ° C and the maximum outside air temperature is set to 16 ° C, when the outside air temperature sensor 70 (Fig. 3) detects an outside air temperature of, for example, 5 ° C, the heat storage amount required for the heat storage chamber 22 is , 40% of the maximum heat storage amount, and the control signal output from the auxiliary controller 68 to the main controller 44 to secure this heat storage amount is 50%. When the control signal of the auxiliary controller 68 is 0, the heat storage amount in the heat storage chamber 22 is 100% which is the maximum heat storage amount, and when it is 80% that does not require heat storage, the heat storage amount is 0 and equal to room temperature. Alternatively, the temperature becomes the temperature due to the residual heat accumulated before that. Therefore, by setting the maximum outside air temperature and the minimum outside air temperature independently, the proportional relationship between the outside air temperature and the heat storage amount changes during this period, and the regional climate such as cold regions and warm regions or the installation location, etc. It is possible to make fine adjustments according to the characteristics of the person, and further, the characteristics of the person such as the feeling of the cold.

に下がる。FIG. 5 shows the relationship between the heat storage body temperature sensor 40 and the auxiliary sensor 46 when the main controller 44 operates the electric switch 48. FIG. 5A shows the operation when the auxiliary controller 68 is not used. In this case, when the detected value 40s of the heat storage body temperature sensor 40 reaches the set value of the B dial, the main controller 44 It operates and shuts off the above-mentioned electric switches 48, 48a. Further, FIG. 5B shows the operation when the main controller 44 and the auxiliary controller 68 are used. In this case,
Detected value 40s of heat storage body temperature sensor 40 and auxiliary sensor 46
When the sum of the detected value 46 s and the detected value 46 s reaches the set value of the B dial, that is, the maximum heat storage position, the main controller 44 operates and heat storage is stopped. Of course, it is also possible to dispose the B dial at a position other than the maximum heat storage position, and in this case as well, the output of the auxiliary controller 68 is proportional to the outside air temperature, so that the heat storage temperature of the heat storage chamber 22 and thus the heat storage amount further decreases. .

(B)). Further, the outside air temperature at which the maximum amount of heat is stored and the outside air temperature that does not require heat storage are set via the E1 and E2 dials of the auxiliary controller 68, and the rate of change of the stored heat amount with respect to changes in the outside air temperature is determined. When the difference between the set temperatures of the E1 dial and the E2 dial is large, the amount of stored heat changes significantly even if the outside air temperature changes slightly, and conversely, when the difference in the set temperature is small, the heat storage amount changes with respect to the outside air temperature change. Fluctuations in quantity are reduced.

４の加熱も停止される。The operation of the heat storage heating device 10 is as follows. For example, when electric power is supplied in a low-priced time zone such as 11 o'clock at night, electric current is supplied to the electric heater 32 in the heat storage chamber 22 via the electric switch 48 to heat the heat storage body 26. The temperature of the heat storage body 26 gradually rises,
This temperature is detected by the main controller 44 through the heat storage body temperature sensor 40. On the other hand, the auxiliary controller 68
The outside air temperature is detected via the outside air temperature sensor 70, and in accordance with the relationship shown in FIG. 4, a control signal corresponding to this outside air temperature is output to heat the control heater 64. This control heater 6
The temperature of 4 is supplied to the main controller 44 via the auxiliary sensor 46.
Detected in. Thereby, as shown in FIG. 5B, when the sum of the detected value 40 s of the heat storage body temperature sensor 40 and the detected value 46 s of the auxiliary sensor 46 reaches the maximum heat storage position, the main controller 44 outputs electric power. The switch 48 is opened to stop heating the heat storage body 26. At the same time, the switch 48a inserted in series with the control heater 64 is also opened, and the control heater 6
The heating of 4 is also stopped.

不足のない熱量が蓄熱室２２内に蓄熱される。When the outside air temperature is high, the output of the auxiliary controller 68 is large, so that the control heater 64 is heated to a higher temperature, whereby the detection value 46s of the auxiliary sensor 46 is increased.
Becomes larger and the detected value 40s of the heat storage body temperature sensor 40 is relatively small, and thus the temperature of the heat storage chamber 22 is low, the main controller 44 operates and the electric switch 48
Opens. On the other hand, when the outside air temperature is low, the output of the auxiliary controller 68 is small, and the heating temperature of the control heater 64 is low. As a result, the detection value 46s of the auxiliary sensor 46 is small, and the heat storage body temperature sensor 40 is relatively low. Detection value of 4
When 0 s is large and therefore the heat storage chamber 22 is heated to a higher temperature, the main controller 68 operates. As a result, the heat storage chamber 22 always stores a sufficient amount of heat with respect to the outside air temperature in the heat storage chamber 22.

In this case, in addition to the case where the B dial is mechanically directly operated, it can be performed by electronic control, for example. By doing so, the auxiliary sensor 46 becomes unnecessary.
