用する家具調コタツには最適であつた。(b) Prior Art Recently, the so-called hot air type has become mainstream in electric kotatsu, replacing the simple radiation type heating unit that has been used for a long time. The reason for this is that in the former heater unit, heat is trapped inside the unit, causing the temperature of each part of the heater unit to rise, which is dangerous, and also causes temperature unevenness in various parts of the kotatsu, resulting in a poor heating effect. For this reason, a hot air type was proposed, which uses a fan to forcibly release the heat inside the heater unit, preventing temperature unevenness in various parts of the kotatsu, and making the heater unit thinner. It was perfect.

ーター或いはフアンまたは遮熱片に及んだ場合が
ある。 However, since the motor was located close to the heater, the motor was exposed to the heater, resulting in performance deterioration and failure. For this reason, for example,
As in Publication No. 55-22016, a heat shield piece that blocks radiant heat from the heater is provided on the member that supports and fixes the motor, but if the height of this heat shield piece is high, it will cover the motor enough to block the heat. However, if the fan blades were to be approached and a shock was applied to the heater unit for some reason, there was a risk that the fan would deform and hit the heat shield, causing the motor to lock up. The first cause of the deformation of the fan mentioned above is that aluminum, which is the easiest to form, is used as the material for the fan, but another factor is that the distortion caused by the deformation of each part can cause damage to the motor, fan, or heat shield. In some cases, this may have occurred.
因みに、遮熱片の高さを低くしてフアンと遮熱
片との距離を離すことが考えられるが、この場合
は遮熱片によるモーターへの熱遮断効果が十分に
得られない欠点となつた。 Incidentally, it is possible to increase the distance between the fan and the heat shield by lowering the height of the heat shield, but in this case, the disadvantage is that the heat shield does not provide sufficient heat insulation to the motor. Ta.

を防止する。(F) Effects of the invention As described above, the present invention has a mounting bracket for fixing the motor that is bent upward along the periphery of the motor and has a plurality of shields whose ends are located below the blower blades of the fan. In addition to forming a thermal wall, a cut portion is provided at the upper corner of the heat shielding wall with its end lowered along the rotating direction of the fan, so that the radiant heat from the heater to the motor is transferred to the heat shielding wall. This prevents deterioration of the performance of the motor and prevents the fan from deforming and hitting the heat shielding wall because the heat shielding wall has a cut portion with its end lowered at the corner on the rotation direction side of the fan. This also prevents the motor from locking up. Further, the heat shielding wall can reinforce the mounting hardware and prevent dust from entering the motor side.
