Description

[Detailed description of the invention] (Technical field) The present invention relates to a drying switching device for a hair dryer.

(Background technology) The hair dryer has a heater to get hot air.

It has a built-in blower, etc., and this heater subt'! t'
It is controlled by the it control circuit.

FIG. 1(a) shows a schematic diagram of this type of control path in the past, and shows a heater l1lI'C triac T.
RI are connected in series, and this triac T
Is RI used as a sensor to detect heater temperature? The thermistor Th and the thermistor 'rh are connected to the capacitor C which is connected to the thermistor Th and the capacitor C which is connected to the thermistor Th and the thermistor 'rh. In order to change the set temperature in this way, a variable resistor RV is connected in series with the thermistor 'v11 to change the integration time.

However, this control means is not suitable. 6, Figure 1 (
If there is an inflection point 'ro in the characteristic value of the resistance change with respect to the resistance change shown in (b), then there is an inflection point 'ro' shown in (c). jru inflection 1 straight 'f's k (thermistor T

Although it is very easy to become compassionate, there is a drawback /ζ.

The thermistor Th, which has a large resistance change per 17K, jl, and ^114, had the disadvantage that it was necessary to keep up with the requirements of the JI variable resistor Rv, and it was difficult to change the design rules.

In order not to hit &'CI-, 7"C, there is no water. Therefore, in this case, the hotter 1b^ wind should be discharged from the air outlet of the dryer.

On the other hand, in Figure (B), contrary to Figure (A), it is not necessary to install one windbreak wall on the outlet side of the hair dryer, and in this case, the heater H
The warm air sent from the side hits the 11th contact sensor -Th', and the wall l prevents the warm air from reaching the sensor ν~-T.

This is a control circuit.

Next, the present invention will be explained in detail.

As shown in Figures (a) and (b), the sensor Y island degree is Not in the upper row. In this case, the sensor Th' ri74 h"j,
Since it consists of a thermistor with a positive characteristic, its resistance value decreases. (7
As a result, the contact time to the condenser C connected in the same line as the thermistor T11 becomes faster, and the control angle becomes smaller than 11'.
Since triac TRI is turned on at point r, heater J
, l to +THTiI41 becomes longer and the heater temperature increases to 144-j, 4). Therefore, the J game IL! is sent out from the air outlet 4! 71.10 can a).

- If you want to lower the power and wind YM1, set the air outlet 41kill &C, and turn the heater on.
If the JL is placed against the windbreak wall 11'c:,r, this warm air will pass through the thermistor'l"b.
9-'rh' is also affected, so sensor hood 1 rule 1

(Effects of the Invention) As described above, according to the present invention, 1. , I', a freely rotatable windbreak wall is provided near the sensor 1, and the windbreak wall is located between the sensor and the sensor, or On the other hand, since it is possible to receive the hot J response from the heater, it is possible to control the characteristics of the sensor by using the VC position.
There is no variable 11 (4,49%) resistance between the C sensor and the capacitor, which has the advantage of stable operation.

The configuration of the control circuit is approximately 17i'i (8, η

Furthermore, as before, there is a possibility that I/ciiJ da 4I (resistance will be filled with dirt in the variable resistor; j) l, -Ci, ;1・111゛1: will decrease. There is, but there is no word for ↓ of Q to in light of tree 1.

In addition, in the case of the type of Acnonamen t/k, the windbreak wall rotates through the interlocking mechanism at Acnonamen 7), and the wind vortex can be automatically switched. There are advantages.
