できない。 Conventionally, electric heating devices installed in the interior of a car, for example at the top of the steering column, consist of a blow-off part, a heater part, an electric fan, and a case that houses these parts, and the heater part is assembled and fixed to the case. There is. Therefore, for example, when only blowing air in the summer, the power to the heater section should be stopped.
Although it is possible to blow air by energizing only the electric fan, the amount of air blown is not sufficient for the occupants to feel cool due to the large pressure loss at the heater section. On the other hand, if the setting is simply to increase the amount of air blown, a cool feeling can be obtained in the summer, but when the heater is used in the winter, the temperature of the hot air decreases due to the increase in power consumption and the entrainment of outside air due to the high wind speed. This leads to a decrease in the feeling of heating. In addition, if the voltage supplied to the electric fan is made variable using a resistor, etc., the device becomes larger because it is necessary to use an electric fan that has the air volume required for summer use, making it unsuitable for use as a heating device installed above the steering column, etc. Appropriate. Furthermore, it is possible to install the heater section so that it can rotate relative to the case, and when the heater is not in use, it can be rotated to an angle that reduces ventilation resistance depending on the shape of the heater section, but it is also possible to install it at the top of the steering column, etc. In a heating device, since the case is small and the cross-sectional area of the ventilation path is small, it is hardly expected that ventilation resistance will be reduced by changing the support angle of the heater section.

するものである。 Therefore, the present invention solves the above problem by installing the heater section in an easily attachable and detachable manner to the case, attaching the heater section when heating is required, and removing the heater section from the case when heating is not required, such as in the summer. It is.
