Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hair dryer device for drying hair.

Conventional technology The drying time of conventional hair dryers is set in advance using a timer, or the drying state of the hair is detected electrically, and the hot air generator is stopped when a predetermined drying state is reached. . An example of the latter method is Utility Model Publication No. 54-2769.

Problems to be Solved by the Invention The timer method described above heats the hair for a fixed period of time regardless of the humidity state of the hair, so there are problems such as insufficient drying or over-drying, and the drying time is selected based on the hair stylist's taste. However, there are drawbacks that often result in the above-mentioned problems.

Although the latter method solves the above problems, it is necessary to adjust the duration of high-temperature hot air blowing in order to obtain desired hair properties or curls. Furthermore, even if the heating temperature is constant, depending on the temperature, the user may feel hot when the room temperature is high, such as in summer, but not when the room temperature is low, so it is necessary to adjust the heating temperature according to the room temperature. is preferred.

In view of the above, an object of the present invention is to automatically adjust the hot air temperature according to the room temperature, so as not to cause discomfort to the user, and to make it possible to arbitrarily set the drying state of the hair.

As will be described later, the heater 4 is composed of heater elements 4a and 4b arranged in parallel so that the temperature can be rapidly raised to a high temperature at the beginning of heating and then adjusted to a set temperature, and is attached to the heater circuit 6.

The dryer device 1 also includes a humidity detection means 10 for detecting the dry/wet state of the hair. This detection means 10 consists of a clip-shaped attachment electrode 11 that holds the hair, and a control circuit 15, which are connected by a cord 16. This mounting electrode 11 is attached to a clip body 12 made of an electrically insulating material as shown in FIG.
Two metal electrode plates 13 and 14 are attached to the tip of the curler C in parallel with a predetermined distance, forming a pair of upper and lower electrodes. Insert it into the dry hair H and hold it,
A weak current is passed between the electrode plates 13 and 14, and the control circuit 15 determines the degree of dryness from the electrical resistance between the electrode plates 13 and 14. In order to visually check the degree of dryness, a light emitting diode (LED), for example, is provided and blinks.

This control circuit 15 is equipped with relays RY1 and RY2, and when a predetermined drying value is reached, one relay is
RY1 is activated to open the normally closed circuit contact RY11 provided in the heater circuit 6, and after a predetermined period of time, the other relay RY2 is activated to open the fan drive circuit 1.
Open the normally closed circuit contact RY21 provided at 8. The time during this period is appropriately set, for example, by a timer (not shown).

Furthermore, this control circuit 15 is equipped with a variable resistor VR1 for appropriately selecting the timing of operating the relay RY1, that is, the degree of drying. This allows you to achieve the desired degree of dryness or wave that is suitable for your hair type.

The dryer device 1 further includes a heating temperature control mechanism 2.
0. This heating temperature control mechanism 20 is
A first heat sensitive element T1 that measures the temperature inside the room, a second heat sensitive element T2 that measures the temperature inside the room, and thermocircuits 21 and 22 that detect signal currents from the respective heat sensitive elements T1 and T2 and generate activation signals. Equipped with. The thermo circuit 21 for the thermosensitive element T1 for temperature measurement inside the main body includes a relay RY3 that opens a normally closed circuit contact RY31 for one heater element 4a.
Equipped with. Further, the thermo circuit 22 for the indoor temperature measuring thermosensitive element T2 is connected to a normally closed contact for the other heater element 4b via the automatic temperature adjustment means 23.
Connected to relay RY4 which opens RY41.

The adjustment means 23 is the relay RY4 at the beginning of heating.
The relay RY4 is operated in consideration of the room temperature after the inside of the main body 2 reaches a predetermined initial temperature. In order to adjust the operating temperature of this relay 4, the adjusting means 23 is equipped with a variable resistor VR2.

In the figure, 25 is a power switch, MS is an electromagnetic switch activated by closing the start switch 26, 2
7 is a circuit operating power source for the humidity detecting means 10 and the like.

In the above configuration, when using the hair dryer device 1, first the attached electrode 11 of the humidity detection means 10 is inserted into the hair H wound around the curler C and held therein. Then, by turning on the power switch 25 and closing the starting switch 26, the electromagnetic switch MS
is activated, closing contact MS1 and energizing heater 4 and fan drive motor M. Accompanying this, the air temperature gradually rises, and this temperature is detected by the first heat-sensitive element T1. and a predetermined initial temperature e.g. 65℃
When reaching , the thermo circuit 21 switches on relay RY3.
is activated to open the circuit contact RY31 of the heater element 4a. Note that this temperature may be adjusted by providing a variable resistor VR3 in the thermo circuit 21.

In this case, even if the temperature inside the main body 2 is constant,
Depending on the temperature, a user may not feel hot when the room temperature is high, but may feel hot when the room temperature is high. The second thermocircuit 22 for room temperature detection opens and closes the circuit contact RY41 of the other heater element 4b according to the room temperature, and after the above-mentioned initial high temperature has been maintained for some time and the circuit contact RY31 of the heater element 4a is opened. , the adjustment means 23 includes thermo circuits 21 and 22.
The signals from both actuate the relay RY4, open and close the circuit contact RY41 of the other heater element 4b, and lower the temperature inside the main body 2, that is, the hot air temperature, to a temperature corresponding to the room temperature. For example, when the room temperature is 20°C, the temperature is set at approximately 55°C, when the room temperature is lower than that, the temperature is slightly higher, and when the room temperature is higher than that, the temperature is slightly lower. This temperature is detected by the first thermal element T1 and applied to the adjustment means 23.

Note that the set temperature in this case may be adjusted by the variable resistor VR2 attached to the adjustment means 23, since the user may be sensitive to temperature and do not like high temperatures.
This is done by

Drying is performed at the set temperature, and when the hair reaches a predetermined dry state, the control circuit 15 detects this and first operates the relay RY1 to open the heater circuit 6. As a result, the air blown by the fan 3 becomes cold air, and after a predetermined time, the relay RY2 is activated and the fan drive circuit 18 is also opened.

In this case, the degree of dryness is adjusted by the variable resistor VR1 to obtain the desired hair quality or curl.

Incidentally, IL in the figure is an infrared lamp, which is provided as necessary to perform drying more effectively.

Effects of the Invention As described above, according to the present invention, the dryness of the hair is detected electrically, the degree of dryness is arbitrarily adjusted, and when a predetermined degree of dryness is reached, the heater circuit is cut off and cold air is sent. Not only can the entire hair be dried uniformly, but also the waves can be adjusted to the desired condition depending on the properties of the hair, thereby preventing insufficient or excessive drying. Furthermore, since the present invention adjusts the hot air temperature according to the indoor temperature, it has the advantage that drying can always be carried out at a comfortable hot air temperature.
