行なうことができない欠点があった。(B) Prior art] Warm air type kotatsu, which discharges hot air into the cod, have been known for a long time, and their heat source can be a normal nichrome wire heater, a lamp, a sheathed heater, or a kotatsu with a positive characteristic whose resistance value changes depending on the temperature. - Mister is used. To control the hot air temperature mentioned above, for example, if a nichrome wire heater is used as the heat source, a thermostat connected in series to the heater is placed between the heater and the hot air outlet to sense the temperature at the outlet. However, there was a drawback that accurate temperature control could not be performed.
その理由として、ファンにより吸気した風の温度をＡ’

感知をすることができなかった。The reason for this is that the temperature of the air taken in by the fan is A'
C, and the temperature rise when heated by the heater is B'C.
Then, the temperature sensed by the thermostat is A 'C + B
However, since the resistance value of the heater varies depending on the variation in individual parts and the amount of heat generated varies, B and C were temperatures that varied, making it impossible to accurately sense the temperature inside the kotatsu. .

- Since it is pressed against the thermostat (16) before heating, the thermostat directly senses the atmospheric temperature inside the kotatsu body (1), allowing accurate temperature control. When the futon is lifted to put the feet in and out, cold outside air is introduced into the warm air unit 6 inside the kotatsu body (1), but this cold air is immediately detected by the thermostat (16). Control is performed according to the atmosphere inside the kotatsu.

る。(F) Effects of the Invention As described above, the present invention has a wind tunnel that is installed inside the kotatsu body and has a fan and a heater inside to form a ventilation passage, and the air taken in by the fan is introduced into the ventilation passage to generate warm air. A thermostat is installed between the fan and the heater, facing into the wind barrel, and connected in series with the heater. This means that the ambient temperature can be sensed, allowing accurate temperature control. Therefore, even if the amount of heat generated varies due to variations in the resistance value of the heater, this temperature will not affect it. In addition, since the Nermoscook I- is provided with a thermostat in the cold air passage compared to the case where the thermostat is provided on the hot air discharge side, there is no need to pay special consideration to the heat resistance temperature of the internal parts of the thermostat. In addition, by removing the thermostat from between the heater and the discharge side, the heater can be moved closer to the discharge side, allowing hot air to be efficiently discharged into the kotatsu body without overheating the excess wind barrel. can do.
