険があった。However, in a state where the legs are folded, as shown in FIG. 1 of the present application, the distal ends of the plurality of legs 1,1,1,1 hit the heater unit 2, and the guard 3 of the heater unit is deformed. As a result, when the distance between the guard and the heater is longer than the designed dimension and the guard is used as a kotatsu, the guard becomes hot and there is a risk of burns. Also, when the leg is folded and used (low table), if the heater is erroneously supplied with electricity, there is a danger that the temperature of the leg rises and thermal deformation occurs.

12の温度調節用のコントローラである。(F) Example An example of the present invention will be described with reference to the drawings. Reference numeral 4 denotes a frame formed in a square (square), and a plurality of inner rails 5a, 5b, 5c, 5
d and a plurality of outer bars 6a, 6b, 6c, 6d surrounding the inner bar. The inner bars 5a, 5b, 5c, and 5d are combined with a girder to form a rectangular storage portion 7 at the center and each end is inclined and combined with the outer bars 6a, 6b, 6c, and 6d. I have. As shown in FIG. 2, the storage portion has its entire outer periphery separated from the frame 4, the corner portion faces the side of the outer bar, and the side portion faces the corner portion of the frame body described later. It is arranged facing the legs. Reference numerals 8a, 8b, 8c, and 8d denote a plurality of legs foldably provided at the corners 9a, 9b, 9c, and 9d of the frame 4, and a base 10 fixed to the frame 4 side and the base 10. And a leg 11 which is rotatably supported so as to be freely foldable in a diagonal direction of the frame 4. Numeral 12 denotes a rectangular heater unit which is housed and fixed in the housing part 7 in a state of being fitted thereto.
A heater and a fan (both not shown) are housed therein. Although not shown, two heaters are provided in parallel with the inner bars 5c and 5d. Sides 14a, 1 of the heater unit 12
4b, 14c, and 14d are fixed toward the corners 9a, 9b, 9c, and 9d of the frame 4, and the sides 14a, 14b, 14c, and 14d are provided.
Is parallel to the side of the storage section 7. Reference numeral 13 denotes a connecting portion provided at the center of the side 14a of the heater unit 12, which is connected to the above-described heater and is provided toward the leg 8a. Each side 14a, 14b of the heater unit 12,
14c and 14d are fixed toward the corners 9a, 9b, 9c and 9d of the frame 4. 15 is a connector 16 connected to the connecting portion 13
Heater unit having a power cord 17 and a power plug 18
Twelve temperature controllers.
斯して、隅角部9a,9b,9c,9dから収納部７を形成する
内桟5a,5b,5c,5dまでの距離は脚11,11,11,11の長さより
も長くなる。換言すれば、脚11,11,11,11は、前記隅角
部から収納部７を形成する内桟5a,5b,5c,5dまでの距離
よりも短い長さとし、折りたたんだ状態ではその先端が
ヒータユニット12はもとより内桟5a,5b,5c,5dまでもと
どかない長さに設定している。Thus, the distance from the corners 9a, 9b, 9c, 9d to the inner bars 5a, 5b, 5c, 5d forming the storage section 7 is longer than the length of the legs 11, 11, 11, 11. In other words, the length of the legs 11, 11, 11, 11 is shorter than the distance from the corner portion to the inner bars 5a, 5b, 5c, 5d forming the storage portion 7, and the ends of the legs 11, 11, 11, 11 in the folded state. The length of the heater unit 12 as well as the inner rails 5a, 5b, 5c, and 5d is set so as not to be lost.
コタツを使用する場合は、夫々の脚11,11,11,11を起
立して垂直状態としコネクター16を連結部13に連結しヒ
ータユニット12によりコタツ内を暖める。When using the kotatsu, the legs 11, 11, 11, 11 are raised to a vertical state, the connector 16 is connected to the connecting portion 13, and the inside of the kotatsu is heated by the heater unit 12.
シーズンオフ、掃除等により壁等に立てかける場合
は、夫々の脚11,11,11,11を折りたたむわけであるが、
この場合、第２図の様に脚は内桟5a,5b,5c,5dから離れ

9aから引き出すことができる。When leaning against a wall etc. during the off-season, cleaning, etc., each leg 11, 11, 11, 11 is folded,
In this case, as shown in FIG. 2, the legs are separated from the inner bars 5a, 5b, 5c, 5d, and one leg 11 is located on the lower surface of the connector 16. This is the case where all the legs 11, 11, 11, 11 are folded and used as a so-called low table on a floor with the legs facing downwards (not shown).
Even if the foot is erroneously stepped on the upper part of the connector 16 without placing the on the upper surface of the frame 4, the connector 16 hits the leg 11 and prevents the deformation of the connector 16 and the connecting portion 13. Also, since the connector 16 can be connected from the corner 9a, the power cord 17 can be pulled out directly to the corner 9a side, so that the power cord 17 is set to the shortest distance and the corner
Can be withdrawn from 9a.
（ト） 発明の効果 以上の様に本発明は、ヒータユニットの側辺を枠体の
隅角部側に向けて固定したものであるから、脚体の折り
たたみ時に該脚体がヒータユニットに当たらないため、
ヒータユニットの変形を防止することができる。(G) Effect of the Invention As described above, in the present invention, since the side of the heater unit is fixed to the corner of the frame, the leg may hit the heater unit when the leg is folded. Because there is no
The deformation of the heater unit can be prevented.
特に、ヒータユニットの収納部は、その側辺を枠体の

できる。In particular, since the housing of the heater unit is formed such that its sides are directed toward the corners of the frame and the periphery thereof is spaced apart from the frame, the external force applied to the frame is transferred to the inside of the frame before the force is transmitted to the housing. Because the heater unit is not dispersed and a large force is not directly applied to the heater unit, and the side of the heater unit is stored and fixed in the storage unit in parallel with the side of the storage unit,
A large-sized heater unit that makes full use of the space of the storage unit can be stored. This uniformly heats a wide area in the electric kotatsu, in other words, it can be mounted on a frame (kotatsu) of a large size.
さらに、内桟の夫々は組み合わせて井桁を形成し、そ

することがない。In addition, each of the inner crosspieces is combined to form a girder, and each end is fixed to the outer crosspiece at an angle, so that the storage section is supported at all ends of the inner crosspiece while being separated from the frame. Thus, the strength of the storage portion and the frame body is increased, and the frame body is not deformed even if the leg body is folded and the frame body is swung right and left when leaning.

邪魔にならない脚体側に導くことができる。In addition, the side of the storage unit faces the leg and is provided at the center of the side of the heater unit, and is located in the space between the inner crosspiece and the corner of the frame, and is directed toward the leg. Since the connector section of the controller is provided, the space in the connection direction required for the connector connection operation can be maximized, and the operation can be performed within a sufficient moving distance from the corner of the frame. As a result, the operation can be simplified, and the cord to be taken out of the heater unit can be guided in a natural state to the leg side which does not disturb the warmer.
