Problems solved by technology

[0004] In this case, not only a detection unit for detecting the air volume or air temperature is required, but also the detection unit needs to be wired, so there is a problem that the cost becomes high and the assemblability is not good.
Moreover, in the switching of the above-mentioned heater supply power, although there is no problem in normal use, for example, in order to accurately dry the scalp, when the air outlet is used close to the scalp, the air temperature will be too high and the air outlet will have to be adjusted. Leaving the scalp, or problems with the wind being too low to dry the scalp well

Embodiment Construction

[0024] One embodiment of the present invention will be described based on the drawings. The heating and air blowing device of this embodiment is connected to the power supply unit D and used. Such as figure 1 As shown, the heating air supply device has: used to drive the fan (refer to Figure 7 12) of the motor M; the heating part H for heating the air flowing by the fan; the detection part N for detecting the voltage or current that energizes the motor M; and receiving the signal from the detection part N (detection result) And the control part C which controls the electric power supplied to the heating part H. As shown in FIG. For example, the control unit C is configured to perform duty ratio control of the electric power supplied to the heating unit H in a preset state corresponding to the detection result.

[0025] figure 2 This is an example in which the power supply unit D is a DC power supply V. In this example, the heating part H is a resistor R, and the detecti...

Abstract

Provided is a heating blow-off apparatus, comprising a fan for blow-off, an electric motor, a heating portion, a detecting portion, and a control portion, wherein the electric motor is used for driving the fan; the heating portion is used for heating the air driven by the fan to flow; the detecting portion is used for detecting the voltage or current electrifying the electric motor; and the control portion is used for controlling the electricity provided for the heating portion according to the detecting result of the detecting portion.

Description

technical field [0001] The invention relates to a heating and blowing device, in particular to a heating and blowing device capable of changing the blowing capacity. Background technique [0002] In the device of AC (alternating current) power supply used in hair dryers used for drying hair and hair sets, the air blowing capacity is usually changed by half-wave or full-wave energization of the air blowing motor (for example, Refer to Japanese Patent Publication No. 60-003485B). At this time, the electric power supplied to the heater for heating can only be controlled according to the air volume or the air temperature so that the air temperature does not become too high when the air volume is reduced. [0003] Therefore, conventionally, a means for detecting the position of a mechanical switch for switching the air volume is provided to switch the heater power supply, or the heater power supply is switched according to the wind temperature detected by the temperature sensor....
