[Technical Field of the Invention] The present invention relates to a heating element unit for a tower kotatsu that is used by being attached to the inner top surface of a tower. [Technical background of the invention and its problems] There is a conventional Yagura Kotatsu that uses a lemon-shaped lamp heater as its heat source. This type of lamp heater has a large diameter (usually 68
mm), for this reason, the net-like guard covering the lamp heater is placed at a low position below the inner ceiling of the tower, which tends to get in the way when temperature is being taken. In addition, only the surface temperature of the lamp heater becomes high, and strong radiant heat is locally radiated from the surface of the lamp heater, resulting in uneven temperature distribution within the tower, resulting in a lack of comfort in heating. Furthermore, the filament temperature of the lamp heater is high (2400〓), so the peak wavelength λp of its radiation is often in the visible light range of about 1.2 μm, and it is difficult to use it in the far-infrared range, which has good heat absorption efficiency for the human body. It's becoming difficult. By the way, a planar heating element is sometimes used as the heat source for a yagura kotatsu, but in this case, even though the radiant heat can be dissipated from a wide area, no visible light is emitted at all, so it is difficult to get a visual sense of warmth. Moreover, there is a drawback that it is not possible to visually confirm whether the current is flowing. [Purpose of the invention] The present invention was made with attention to these points, and its purpose is to secure a large heating space in the lower part of the inside of the tower, and to prevent the inside of the tower from far infrared rays and visible light. An object of the present invention is to provide a heating element unit for a tower kotatsu, which can heat each part substantially uniformly and efficiently. [Summary of the invention] The invention consists of a rod-shaped light emitting heat source attached to the surface of a radiant plate having a far-infrared radiation layer on the surface. [Embodiment of the invention] An embodiment of the invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a tower, and holding bars 2 are provided on the inner top surface of the tower 1. A metal reflecting plate 3 is supported inside the holding bars 2 via pins 4 inserted through the holding bars 2. Radiating plates 5 are attached to the lower surface of the reflecting plate 3 at regular intervals via heat-insulating supporting pieces 6. A far-infrared radiation layer 7 formed by coating a zirconia-based ceramic material, a metal oxide, a silicate compound, etc. is applied to the lower surface of the radiation plate 5. For example, two parallel rows of inverted U-shaped cross sections are formed on the far-infrared radiation layer 7. Concave grooves 8, 8 are formed. A rod-shaped luminescent heat source, for example, a quartz tube heater 9, which is made by inserting a heater wire into a quartz tube, is attached to each of the grooves 8, 8, and these quartz tube heaters 9, 9 are placed in contact with the radiant plate 5. The radiation plate 5 is connected to the holder 10 through the holder 10, respectively.
installed on. Further, the periphery and lower part of the radiation plate 5 are covered and protected by a net-like guard 11. In the heating element unit constructed in this manner, when the quartz tube heaters 9 are energized, they emit visible light and generate heat. Then, the heat of the quartz tube heaters 9, 9 is absorbed by the radiant plate 5, and as a result, the temperature of the radiant plate 5 rises to about 95 to 150°C, and
The temperature rise on the surface of the quartz tube heaters 9, 9 is suppressed, and the temperature is maintained at a relatively low temperature of about 170 to 185°C. As the temperature of the radiating plate 5 rises, far infrared rays having a peak wavelength of about 7 μm are uniformly radiated from the entire surface of the radiating plate 5 through the far infrared radiation layer 7 to the lower part of the tower 1. The inside of the tower 1 is heated by this far infrared rays and radiation generated by the heat generated by the quartz tube heaters 9, 9, but the quartz tube heaters 9, 9 are kept at a relatively low temperature, and the far infrared rays are radiated from the entire surface of the radiator plate 5. As a result, the temperature distribution inside the tower 1 becomes uniform, a soft feeling of warmth is obtained, and far-infrared rays improve heat absorption to the human body, making it possible to achieve efficient warming. In addition, a visual sense of warmth can be obtained by the visible light from the quartz tube heaters 9, and energization can also be visually confirmed. Furthermore, since this heating element unit is made up of rod-shaped quartz tube heaters 9, 9 attached to a flat radiant plate 5, the entire structure is flat and thin, and for this reason, the guard 11 is placed at an upper position within the tower 1. As a result, a large heating space can be secured within the tower 1, improving usability. The following table compares the specifications of the device of the present invention and that of a conventional device using a lemon-shaped lamp heater.

Moreover, it has the effect of securing a large space for heating inside the tower and improving its usability.
