DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater for heating a garment for finishing the clothes, the power supplied to the load is controlled by a switching unit via a driving unit, and the driving unit is controlled by a control unit. The present invention relates to a clothing finisher controlled by a garment.

[0002]

2. Description of the Related Art Conventionally, a clothes finishing machine of this type, for example, an iron as shown in FIG. 8 has been proposed. Hereinafter, the configuration will be described.

As shown in FIG. 1, a rectifying unit 2 for rectifying a voltage of a commercial power supply 1 and a voltage dropping unit 3 for dropping an output voltage of the rectifying unit 2 constitute a power supply unit 4. The heater unit 5 as a load unit is connected in series to the switching unit 6, and the switching unit 6 is on when the commercial power supply 1 is turned on. The drive unit 7 drives the switching unit 6 and is controlled by the control unit 8. The sensor unit 9 detects whether the clothes finishing device main body (iron) is in a use state or a non-use state.

The driving unit 7, the control unit 8, and the sensor unit 9 are configured to rectify the voltage of the commercial power supply 1 by the rectification unit 2 and apply the voltage dropped by the voltage drop unit 3 to operate. .
Reference numeral 10 denotes a thermostat which turns on and off by detecting a base temperature heated by a heater portion (load portion) 5 of the clothes finishing device main body (iron), and keeps the base temperature constant when the switching portion 6 is on. To keep.

[0005] As shown in FIG.
When the clothing finisher main body 11 is used, the clothing finisher main body 11 is moved, and as shown in FIGS. 9B and 9C, the clothing finisher main body 11 is left unattended when not in use. The movement of the clothing finishing device main body 11 is detected, and if it is moving, it is determined that it is in use, and if it is stationary, it is determined that it is not in use.

The sensor section 9 is constructed as shown in FIG. 10. A photocoupler 13 enclosing a light-emitting element and a light-receiving element is provided below the inclined bottom surface of a case 12, and a ball 14 is moved into the case 12. I put it freely. The sensor unit 9 is connected as shown in FIG. 11, and the light of the light emitting element 13a of the photocoupler 13
The light enters the light receiving element 13b and is reflected by the light receiving element 13b.
b is turned on, or the light of the light emitting element 13a is
3b, the light receiving element 13b is turned off.

Therefore, if the collector voltage Vc of the light receiving element 13b is detected and the voltage Vc generates a pulse voltage as shown in FIG.
Is determined to be in use, and if the collector voltage Vc is fixed at a low level or a high level as shown in FIGS.

When a pulse voltage is not input from the sensor unit 9 (ie, when the sensor unit 9 is not in use), the control unit 8 counts a predetermined time, and after the predetermined time elapses, drives the driving unit 7, and the driving unit 7 performs switching. The unit 6 is turned off, and the power supply to the load unit, that is, the heater unit 5 is stopped.

During use of the clothing finisher body 11, a pulse voltage is input from the sensor unit 9 to the control unit 8,
When the pulse voltage rises or falls, the clock of the control unit 8 is reset to 0, the time count does not reach the predetermined time, and the switching unit 6 continues the ON state.

[0010]

However, in such a conventional configuration, the driving unit 7 is connected in parallel with the output of the voltage drop unit 3.
Since the control unit 8 and the sensor unit 9 are connected, when the current flowing to the driving unit 7 is i1, the current flowing to the control unit 8 is i2, and the current flowing to the sensor unit 9 is i3, the current flows to the voltage drop unit 3. The current is (i1 + i2 + i3).

If the voltage applied to each part is V2, the voltage V2 to be applied is relatively low when each part is a circuit composed of a semiconductor such as an integrated circuit or a transistor. Assuming that the voltage is input to the section 2 and the output voltage is V1, (V1-V2) becomes a large value. Therefore, the power consumption in the voltage drop unit 3 is (V1−V2) × (i1 + i2 + i3), and this value is a large value, and the amount of heat generated in the voltage drop unit 3 is large.

Therefore, the voltage drop section 3 cannot be mounted on the printed circuit board, and must be mounted outside the printed circuit board 16 by the lead 15 as shown in FIG. Thus, when the voltage drop section 3 is provided outside the printed circuit board 16,
When the voltage drop section 3 is formed of the resistor 17, it is necessary to use the tube 18 for the purpose of ensuring electrical insulation of the resistor 17 by contact with other portions, or not heating other contact portions. There are problems such as high price and difficulty in assembling. In addition, when the space for mounting the electronic circuit unit is small like an iron, mounting is very difficult.

As a solution to this problem, the one shown in FIG. 14 has been proposed. In this case, the drive unit 7, the control unit 8, and the sensor unit 9 are connected to the power supply unit 4 in series.
At this time, the output voltage of the rectifier 2 for rectifying the commercial power 1 is V1, the voltage applied to the driver 7 is V2, the voltage applied to the controller 8 is V3, and the voltage applied to the sensor 9 is V4.
Then, the voltage applied to the voltage drop unit 3 is V1- (V
2 + V3 + V4), which is a relatively small value.

Further, of the current required to operate the drive unit 7, the current required to operate the control unit 8, and the current required to operate the sensor unit 9, What is necessary is just to flow an electric current to the series circuit of the drive part 7, the control part 8, and the sensor part 9.

Therefore, the power consumption of the voltage drop section 3 of the power supply section 4 is represented by [V1− (V2 + V3 +) when the current flowing through the series circuit of the drive section 7, the control section 8, and the sensor section 9 is i1.
V4)] × i1, which is a small value, and the heat generation of the voltage drop unit 3 is small. Therefore, as shown in FIG. 15, the resistor 17 forming the voltage drop section 3 is connected to the printed circuit board 1.
6 can be implemented. This specific circuit diagram is shown in FIG.

However, in this case, since the resistance value of the driving unit 7 is greatly different between when the driving unit 7 is on and when it is off, the driving unit 7 may not operate smoothly.

That is, in FIG. 16, Vac is a commercial AC power supply, and a voltage of a predetermined value is obtained by a power supply unit 4 composed of a diode D1 and a voltage drop resistor R1. This voltage is applied to a series circuit of the driving unit 7, the control unit 8, and the sensor unit 9. The drive unit 7 drives the switching unit 6, and the switching unit 6 turns on and off the commercial AC power supply Vac supplied to the heater unit (load unit) 5. The thermostat 10 detects the temperature of the heater unit 5 and turns on and off the circuit of the heater unit 5 for control.

The switching section 6 is constituted by contacts of a relay, and the coil section RL of the relay constitutes a driving section 7.
Therefore, when the coil portion RL of the relay is turned on, the contact of the relay is closed, and power is supplied to the heater portion 5. When the coil portion RL of the relay is turned off, the contact of the relay is opened, and power is supplied to the heater portion 5. Is stopped.

The transistor Q1 controls the relay coil RL. When the transistor Q1 is turned on, a current flows through the relay coil RL. When the transistor Q1 is turned off, the current flowing through the relay coil RL is reduced. It is shut off and the relay contact turns off.

The diode D2 removes a surge voltage generated at both ends of the relay coil RL to protect the transistor Q1, and the capacitor C1 smoothes the voltage applied to the drive unit 7 to make it DC. . The Zener diode ZD1 is for making the voltage applied to the drive unit 7 a constant voltage. The operations of the control unit 8 and the sensor unit 9 are as described above.

In this circuit configuration, when the transistor Q1 is turned on, the current from the power supply unit 4 flows to the control unit 8 and the sensor unit 9 through the Zener diode ZD1 and the relay coil RL. However, the transistor Q1
Is turned off, the current from the power supply unit 4 has only a path passing through the Zener diode ZD1. Therefore, only when the power supply voltage is high and the voltage V2 applied to the drive unit 7 is equal to or higher than the Zener voltage of the Zener diode ZD1, the control unit 8 Current can be supplied to the sensor unit 9.

Therefore, when the commercial AC power supply Vac drops, no current is supplied to the control unit 8 and the sensor unit 9 and an operation failure occurs. In order to satisfy the operation at a low voltage of the commercial AC power supply Vac, the value of the voltage drop resistor R1 must be set small and the circuit current i1 must be set large, and as a result, the power consumption of the voltage drop resistor R1 is reduced. There was a problem that the heat generation increased.

The present invention solves the above-mentioned conventional problems. The power consumption of the voltage drop section is set small to reduce heat generation, enable mounting on a printed circuit board, and operate at a low voltage of a commercial power supply. It is intended to satisfy the following, and also to satisfy the operation at the time of the momentary power failure of the commercial power supply.

[0024]

According to the present invention, in order to achieve the above object, a commercial power supply is rectified by a rectifying section constituting a power supply section, an output voltage of the rectifying section is dropped by a voltage drop section, and a load section is provided. The power supplied to the power supply is controlled by a switching unit, the switching unit is driven by a driving unit, and the driving unit is controlled by the control unit. The drive unit and the control unit are connected in series to a power supply unit, and the second load unit is connected in parallel to the drive unit.

As a result, heat generation can be reduced by setting the power consumption of the voltage drop section to be small, enabling mounting on a printed circuit board, satisfying the operation of a commercial power supply at a low voltage, and further satisfying the commercial power supply. The operation at the moment of an instantaneous power failure can also be satisfied.
