Description
【発明の詳細な説明】 (イ)産業上の利用分野 本発明は例えば電気コタツとして最適な温風式ヒーター
ユニットに関する。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a hot air heater unit which is optimal as an electric kotatsu, for example.
(ロ)従来技術 最近電気コタツは所謂温風式が主流になりつつある。そ
の理由としては古くから用いられてきたヒーター単体に
よる輻射式のみのヒーターユニットは熱が該ユニット内
にこもりヒーターユニットの各部の温度が上昇し危険で
あると共にコタツ内の各部に温度ムラを生じ採暖効果の
悪いものであった。このため、温風式が提唱されファン
によってヒーターユニットの内部の熱を強制的に放出し
且つコタツ内の各部の温度ムラを防止するようにした。
又、この結果、ヒーターユニットを薄くすることがで
き、年中使用する家具調コタツには最適であった。(B) Conventional technology Recently, the so-called warm air type is becoming the mainstream of electric kotatsu. The reason is that the radiant type heater unit with a single heater, which has been used for a long time, is dangerous because heat accumulates in the unit and the temperature of each part of the heater unit rises, and temperature unevenness occurs in each part of the kotatsu It was a bad effect. For this reason, the hot air system has been proposed, and the fan forcibly releases the heat inside the heater unit and prevents the temperature unevenness of each part in the kotatsu.
Further, as a result, the heater unit can be made thin, which is suitable for furniture-like kotatsu used all year round.
ところが、あらたな問題点としてファンを駆動するモー

た前記遮熱板は非常に高温となり十分な効果が得られず
必然的に遮熱板とヒーター或いは遮熱板とモーターとの
距離が長くなりヒーターユニットの厚さを最少限にする
ことができなかった。However, as a new problem, the motor that drives the fan was exposed to the heater, resulting in performance degradation and failure. Therefore, although the motor is covered with a heat shield as in Japanese Utility Model Publication No. 57-195052, for example, the heat shield located in the vicinity of the heater becomes extremely hot and a sufficient effect cannot be obtained. As a result, the distance between the heat shield plate and the heater or the heat shield plate and the motor becomes long, so that the thickness of the heater unit cannot be minimized.
因みに前述のヒーターユニットにおいてもファンによる
風はモーターの一部を若干冷却するが十分な冷却効果が
得られなかった。即ち、モーターに取付けた送風用ファ
ンは該ファンの周縁部の風が一番強く内側に行くに従い
弱く放出する性質を備えているために、ファンの周縁部
と最も離れた位置にあるモーターには冷却される程度の
風量が得られなかった。By the way, even in the above-mentioned heater unit, the wind by the fan slightly cooled a part of the motor, but a sufficient cooling effect was not obtained. That is, since the blower fan attached to the motor has the property that the wind at the peripheral edge of the fan is strongest and weakly discharged toward the inner side, the motor at the position farthest from the peripheral edge of the fan is not The air volume for cooling was not obtained.

きる。(F) Effects of the Invention As described above, the warm air heater unit of the present invention is provided with the cooling blades that apply wind to cool the motor and the warm air blades that apply wind to the heater to warm the air, Since it has a flat fan formed by bending the blade and the warm air blade from the same plane, the rotation of the fan can efficiently cool the motor by the cooling blade, and the warm air blade heats the heater. Can be warmed and released efficiently. In particular, since the fan includes the cooling blade and the warm air blade, it is possible to more efficiently cool the motor and warm the heat of the heater even when the diameter of the fan is increased. Furthermore, since the fan has a flat plate shape in which the cooling blade and the warm air blade are bent from the same surface, the heater unit can be made thinner.
