[Problem to be solved by the invention] In the hair dryer as described above, in order to obtain the "air volume x air temperature" suitable for the purpose of use, each switch of the air volume variable means and the air temperature variable means must be operated several times. There is a need to. For example, if the air volume and air temperature are controlled using three-level switches (strong/medium/low, high/medium/low), the selections for "air volume" and "air temperature" are "strong" and "high," respectively. If you try to change from "Strong" to "Weak" and "Low", you will need to perform a total of four operations: two steps from "Strong" to "Weak" and two steps from "High" to "Low" (for example,
JP-A-62-246310).

[0005] The present invention was made in view of the above circumstances, and its purpose is to
To provide an easy-to-use hair dryer that instantly adjusts air volume x air temperature.

[0006]

[Means for Solving the Problems] In order to achieve the above object, a housing having an inlet and an outlet, a blowing means and a heating means built into the housing, and a blowing means and a heating means arranged in several stages are provided. an air volume variable means and an air temperature variable means for controlling the air volume and air temperature to vary the air volume and air temperature; and a switch operation means for selecting a stage of controlling the air volume and air temperature of the air volume variable means and the air temperature variable means. In the hair dryer, the switch operation means includes an input section for inputting control data for controlling the air volume variable means and the air temperature variable means to predetermined levels, a storage section for storing the control data, and a storage section for reading the stored control data. The configuration includes a calling section and a control section that drives and controls the blowing means and the heating means according to the called control data.

It has a handle part 1f that is grasped and held during operation, and a cord holding part 1g that holds a power cord B on the handle part 1f.

Reference numeral 2 denotes a blowing means, which comprises a fan (not shown) configured to send air from the suction port 1a to the discharge port 1b, and a motor fixed to the output shaft of the fan.

3 is a heating means, and a heater stand 3a is supported by engaging with ribs etc. formed on the inner wall of the housing 1.
and a heater (not shown) formed of a resistance wire wound around the heater stand 3a, and is held in the flow path 1c of the housing 1 on the discharge port 1b side.

Reference numeral 4 denotes an air volume variable means, in which a plurality of resistors 5 and contact switches 6 for short-circuiting the resistors 5 are connected in series, and a power supply section 15 and a blower means 2, which will be described later, are connected in series.
is connected between one terminal of the motor. This contact switch 6 is controlled to open and close by a control section 13, which will be described later. The circuit resistance between the power supply section 15 of the air volume variable means 4 and the motor becomes smaller as the number of "closed" contact switches 6 increases. As this circuit resistance becomes smaller, the voltage applied to the motor becomes higher, the rotational speed of the motor increases, and the amount of air sent by the air blowing means 2 increases. Conversely, as the number of "open" contact switches 6 increases, the circuit resistance increases, the voltage applied to the motor decreases, the rotational speed of the motor decreases, and the amount of air sent by the ventilation means 2 decreases.

Reference numeral 7 denotes an air temperature variable means, in which a plurality of parallel-connected resistors 5 and contact switches 6 for short-circuiting the resistors 5 are connected in series, and a power source section and a heating means 3, which will be described later, are connected in series.
is connected between one terminal of the heater. This contact switch 6 is controlled to open and close by a control section 13, which will be described later. The circuit resistance between the power supply section 15 of the air temperature variable means 7 and the heater becomes smaller as the number of contact switches 6 that are "closed" increases, and conversely, as the number of "open" contact switches 6 increases, the circuit resistance resistance increases. This air temperature variable means 7 raises the temperature of the heater by increasing the voltage applied to the heater as the circuit resistance becomes smaller, thereby increasing the temperature of the air passing through the heating means 3. Further, as the circuit resistance increases, the voltage applied to the heater is lowered to lower the temperature of the heater, thereby keeping the temperature of the air passing through the heating means 3 low.
