Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a wall-mounted or screen-type panel heater.

(Prior Art) This type of panel heater generally consists of two heater sections, upper and lower, and is equipped with a temperature regulator such as a thermostat to control these upper and lower heater sections. In this prior art panel heater, the upper and lower heater sections had the same heat generation density (output), and the thermostats had the same set temperature. However, with this structure, even when the temperature is still relatively high, such as in late autumn or early spring, the upper and lower heater parts are energized, resulting in uncomfortable warmth, and the feet are cold and the face is hot, making it feel too hot. Furthermore, when the thermostat in the lower heater section is activated due to wind blowing or people passing by, the heat in the upper heater section escapes downwards, making it difficult for the thermostat in the upper heater section to detect this. There was a drawback that the power remained energized.

(Purpose of the invention) An object of the invention is to provide a panel heater that can perform comfortable heating by controlling the upper and lower heater portions well.

(Structure of the invention) The panel heater of the invention consists of two heater sections, upper and lower, and is equipped with a temperature regulator that controls the upper and lower heater sections, but the lower heater section has a higher heat generation density than the upper heater section. The set temperature of the temperature regulator of the upper heater portion is set lower than the set temperature of the temperature regulator of the lower heater portion.

In this way, the heat generation density of the lower heater section is made higher than that of the upper heater section, so the lower side of the room is warmer than the upper side, and the temperature setting of the temperature controller is set higher for the upper heater section than for the lower heater section. Since the temperature is lowered, the upper heater section is energized for a short time, allowing comfortable temperature control.

(Embodiment) An embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 1A and 1B show a panel heater 10 according to the present invention, and the panel heater 10A in FIG. 1A heats a wall 12. The panel heater 10B of FIG. 1B is shown to be of the screen type. The screen-type panel heater 10B consists of a planar heating element 18 provided on a heat insulating material 16, a back plate 20 is provided on the back surface thereof, and a metal top plate 22 is provided on the front surface. There is.

As shown in FIG. 2, each panel heater 10A, 10B has upper and lower heater portions 24A, 24B provided in two stages, upper and lower, and a temperature control device such as a thermostat that controls the energization of each heater portion. It consists of vessels 26A and 26B. These heater parts 24A, 24B and temperature regulator 26A,
26B are connected in series, as shown in FIG. 3, and both series circuits are connected to the power switch 28B.
It is connected in parallel to the AC power supply 30 via.
In addition, in FIG. 3, the reference numeral 32 indicates the upper heater portion 2.
4A from the lower heater portion 24B so that only the lower heater portion 24B is energized.

In the panel heater 10 of the present invention, the lower heater part 24B has a higher heat generation density than the upper heater part 24A, and the set temperature of the temperature controller 26A of the upper heater part 24A is equal to the setting of the temperature controller 26B of the lower heater part 24B. It is set lower than the temperature.

In this way, when the room temperature is low, both temperature regulators 26A and 26B are closed and the upper and lower heater parts 24A and 24B are energized to warm the entire room, and when the room temperature is high, the temperature regulator 26B is closed.
The chisel closes to keep your feet warm. Further, since the lower heater portion 24B has a higher heat generation density than the upper heater portion 24A, the temperature at the feet is always higher and comfortable heating can be performed. FIG. 4 shows the state of the room temperature using the panel heater of the present invention, and as can be seen from this figure, the feet are always warmer.

One specific example of this invention has a width of 830 mm.
It is a wall-mounted heater with a height of 1300 mm and a depth of 25 mm.The planar heating element is 600 x 750 mm, the upper heater part is 380W, and the lower heater part is 430W.The thermostat setting temperature is 80°C at the top and 90°C at the bottom. And so. It was confirmed that this panel heater was able to provide comfortable heating.

(Effects of the Invention) As described above, the present invention has the practical benefit of being able to comfortably heat the entire room by properly controlling the upper and lower heater parts so that the feet are always warmer than the face.
