【考案の詳細な説明】
本考案は、面状発熱体を熱源としてやぐら内を
加熱するやぐらこたつに関する。[Detailed Description of the Invention] The present invention relates to a tower kotatsu that heats the inside of a tower using a planar heating element as a heat source.
従来のやぐらこたつの発熱体としては赤外線ラ
ンプ、コルツランプ、シーズヒータ等があるが、
発熱体自体の形状が大きく、その保護網の大きさ
も法規制の温度域に入るためには大きくならざる
を得ず、こたつ内のスペースはその分狭くならざ
るを得ない。また、ランプを用いたものは可視光
分だけその熱損失分が多く。 Conventional heating elements for Yagura Kotatsu include infrared lamps, Kortz lamps, sheathed heaters, etc.
The shape of the heating element itself is large, and the size of its protective net must also be large in order to stay within the legally regulated temperature range, and the space inside the kotatsu must be reduced accordingly. Also, with lamps that use visible light, there is a lot of heat loss due to the amount of visible light.
また、シーズヒータの場合にはこたつ内の温度
分布が均一でなく、立上り特性も採暖者が満足で
きるものでなかつた。 Furthermore, in the case of a sheathed heater, the temperature distribution within the kotatsu was not uniform, and the rise characteristics were not satisfactory to the person taking the heat.

くい。等の欠点を有していた。 Therefore, the Yagura Kotatsu, which combines an infrared lamp and a sheet heating element, was devised to increase the space inside the kotatsu. (For example, see Japanese Utility Model Application Publication No. 49-133075.) However, in this system, (a) although the power consumption is low, since an infrared lamp is used, heat loss occurs due to visible light. (b) Since an infrared lamp is used, the thickness of the heat generating device is inevitably thicker, and although the space inside the kotatsu is wider than when using only an infrared lamp, it is not satisfactory to the person taking the heat. (c) There is a heat radiating plate and a protective net below the lamp, and most of the heat radiated from the lamp is absorbed by the protective net, so only a small amount of the radiated heat reaches the floor. (d) Due to the characteristics of radiant heat (radiated perpendicular to the heating surface), the temperature distribution inside the kotatsu is difficult to be uniform. It had the following drawbacks.

などの熱ロスとなり不経済であるといつた問題を
有していた。 Therefore, in recent years, flat heating elements made of mica, asbestos, glass wool, etc. coated with highly radioactive materials and thin tower kotatsu using carbon heaters have become known.
(For example, see Japanese Utility Model Application Publication No. 49-68583.) However, in the conventional tower kotatsu that uses a planar heating element, the planar heating element is located below the lower end surface of the kotatsu beam, so the surface of the heating element is The generated convection heat is transferred along the back surface of the top plate, resulting in the temperature distribution inside the kotatsu being high at the top and low at the bottom, and the heat stagnant at the top heats up the top plate. The problem was that it caused heat loss and was uneconomical.
本考案は、上記事情にもとづきなされたもの

つを提供しようとするものである。 The present invention was developed based on the above circumstances, and its purpose is to utilize the characteristics of radiant heat to fully utilize the characteristics of radiant heat, and to use the generated convection heat to reduce the damage caused by the heating of top plates, futons, etc. The purpose is to provide a tower kotatsu that suppresses upward heat transfer loss as much as possible.

The heat insulating plate 9 is attached to seal the upper end opening of the rectangular cylindrical frame 15 of the protector 4. First and second air layers (insulating layers) 1 having a completely sealed structure are formed between the mutually opposing surfaces of the planar heating element 7 and the reflecting plate 8 and between the mutually opposing surfaces of the reflecting plate 8 and the heat insulating plate 9.
6 and 17 further include a third air layer (insulation layer) 1 having a semi-sealed structure between the mutually opposing surfaces of the insulation board 9 and the top plate 2.

る。 The protector 4 has a structure including the frame 15 that surrounds the side surface of the heat generating device 5 and a net 21 such as a lath net that covers the lower surface of the heat generating device 5. The edge extends downward from the lower surface of the planar heating element 7 and forms a convection prevention wall 22 .

を暖めることになる。 Next, the effect will be explained. When the heater 10 is energized, the planar heating element 7 generates heat, and in conjunction with this heat generation, far infrared rays are emitted from the far infrared radiation layer 14. The emitted far-infrared rays are irradiated downward through each mesh of the net body 21, thereby warming the inside of the tower 1.

に採暖に供される。 At this time, since the lower end edge of the frame 15 of the protector 4 extends downward from the lower surface of the planar heating element 7 to form a convection prevention wall 22, the radiator 4
Thermal energy including convective heat emitted from the far-infrared radiation layer 14 is transmitted downward, and the thermal energy from the entire surface of the far-infrared radiation layer 14 is effectively used for heating.

換する割合が大きくなる。 On the other hand, the thermal energy emitted from the back surface (top surface) of the planar heating element 7 is reflected and insulated by the reflective plate 8 present through the first air layer (insulating layer) 16 having a completely sealed structure. The heat insulating plate 9 exists on the plate 8 via a second air layer (insulating layer) 17 having a completely sealed structure, and the heat insulating effect is further enhanced. Furthermore, a third air layer (insulating layer) 18 with a semi-sealed structure is provided between the heat insulating board 9 and the top plate 2.
is formed, the heat transfer loss to the top plate 2 is extremely small, and the ratio of input energy to radiant energy is increased.
