[0002]

2. Description of the Related Art Conventionally, a cordless iron of this type has been proposed as shown in FIGS. That is, when the iron unit 1 is placed on the stand unit 2, the heater unit 4 for heating the base unit 3 of the iron unit 1 is connected to the stand unit 2 via the electrode unit 5 provided on both the iron unit 1 and the stand unit 2. Is connected to the second control circuit section 6 provided in the first section, and power is supplied to the heater section 4 to be heated.

The first control circuit 7 provided in the ironing section 1
Controls the temperature of the base unit 3 by detecting and processing the temperature of the base unit 3 and sending the detected temperature signal to the second control circuit unit 6 of the stand unit 2 via the electrode unit 8. It has become.

The first control circuit unit 7 includes a base unit 3
A temperature detecting section 9 for detecting the temperature of the display section, a display section 10 driven by an output of the temperature detecting section 9, and a detected temperature signal obtained by detecting the temperature of the base section 3 by the temperature detecting section 9. A temperature signal transmission circuit for sending to the second control circuit unit 6 is provided.

[0005] Further, the iron part 1 is connected to a stand part 2.
Has a power supply unit 12 connected to the commercial power supply 11 of the stand unit 2 via the electrode unit 8 when supplying the power to the first control circuit unit 7 of the ironing unit 1. The output voltage of the power supply unit 12 is input to the power storage unit 13, and charges the power storage unit 13 when the iron unit 1 is placed on the stand unit 2.

When the iron unit 1 is placed on the stand unit 2 and the base temperature rises and reaches the set temperature, the iron unit 1 is detached from the stand unit 2 and ironing is started. Therefore, the output voltage of the power supply unit 12 is zero. Therefore, the first control circuit unit 7 of the ironing unit 1
3 operates with the output voltage. Among the first control circuit units 7 driven by the output voltage of the power storage unit 13, the temperature detection unit 9 detects the base temperature lowered by ironing, operates the display unit 10, and switches the iron unit 1 to the stand unit 2.
To notify that the base needs to be heated.

However, in such a structure, even when the ironing unit 1 is detached from the stand unit 2, the entire first control circuit unit 7 is stored in the power storage unit 13.
Iron unit 1 is operated by stand unit 2
A signal other than the circuit that needs to operate when the device is disconnected from the base unit, that is, a temperature signal transmitted to the second control circuit unit 6 of the stand unit 2 by processing a detected temperature signal that detects the temperature of the base unit 3 Since power is supplied to the circuit, the power consumption is increased, and the power storage unit 13 having a large capacity is required to secure a sufficient time for operating the temperature detection unit 9 and the display unit 10. However, there is a problem that the circuit configuration becomes large.

Accordingly, an object of the present invention is to provide a cordless iron that is easy to use by reducing the circuit configuration with a small-capacity power storage unit.

[0009]

In order to achieve the above object, the present invention comprises an ironing section and a stand section having a commercial power supply on which the ironing section is mounted. A heater for heating the base, a temperature detector for detecting the temperature of the base, a display driven by the temperature detector, and a temperature signal detected by the temperature detector transmitted to the stand. A control circuit unit having a temperature signal transmission unit, a power supply unit connected to a commercial power supply of the stand unit by electrodes provided on both the iron unit and the stand unit, and a power storage unit charged by an output of the power supply unit, A voltage detection unit that detects a voltage of the power supply unit and a voltage of the power storage unit, and a switching unit that operates by an output of the voltage detection unit, wherein the switching unit includes the iron unit. When detached from the stand unit, it is obtained by from the power storage unit by the output of the voltage sensing unit configured to supply power only to the display unit and the temperature detecting portion of the control circuit unit.

[0010]

According to the present invention, when the iron is placed on the stand, the power supply of the iron is connected to the commercial power supply of the stand. A power supply having a capacity is obtained, whereby power is supplied to the entire control circuit unit that performs various functions of the ironing unit, and the power supply unit charges the power storage unit.

When the iron is detached from the stand for ironing and the control circuit of the iron operates by the output voltage of the power storage unit, the voltage detector detects a different voltage from the output voltage of the power supply. By detecting the output voltage of the section and operating the switching section, it becomes possible to selectively supply power to only a part of necessary control sections of the control circuit section of the iron section. Therefore, the load on the power storage unit can be reduced, and the power storage unit with a small capacity can be driven for a predetermined time.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 20 denotes an iron unit having a base unit 22 heated by a heater unit 21, and a cordless iron including a stand unit 24 having a commercial power supply 23.

When the iron unit 20 is mounted on the stand unit 24, power is supplied from the commercial power supply 23 of the stand unit 24 to the heater unit 21 through the first control circuit unit 25 and the electrode unit 26 provided in the iron unit 20. The base 22 is heated.

The first control circuit section 25 has a temperature detecting section 27 for detecting the temperature of the base section 22 and a display section 28 driven by the output of the temperature detecting section 27. Base unit 2 detected by detection unit 27
2 is provided with a temperature signal transmission unit (not shown) for performing signal processing on the temperature of 2 and transmitting the processed signal to the second control circuit unit 30 provided in the stand unit 24 through the electrode unit 29.

Reference numeral 31 denotes a power supply unit connected to the commercial electrode 23 by the electrode 29 when the iron unit 20 is placed on the stand unit 24. Each circuit unit of the iron unit 20 is operated by the commercial power supply 23 of the stand unit 24. The voltage is converted into a voltage required for operation, and the output of the power supply unit 31 is input to the power storage unit 32 to charge the power storage unit 32. 33 is a voltage detection unit that detects the output voltage of the power storage unit 32 that outputs a voltage different from the output voltage of the power supply unit 31 and the voltage of the power supply unit 31;
Reference numeral 34 denotes a switching unit that selectively supplies power to the first control circuit unit 25 based on the output of the voltage detection unit 33.

Next, the operation of the configuration of this embodiment will be described. First, when the iron unit 20 is placed on the stand unit 24, the power supply unit 31 has an output voltage.

The processing signal is transmitted to the electrode unit 29.
The second control circuit unit 30 provided in the stand unit 24 through the
In addition to operating the temperature signal transmission unit to transmit to, for example,
It is also conceivable that the water level of a water tank (not shown) provided in the ironing section 20 is detected, and this water level signal is sent to the second control circuit section 30 of the stand section 24 through the electrode 29 together with the temperature signal. , All the functions of the first control circuit unit 25 operate.

Then, when the temperature of the base portion 22 rises and reaches the set temperature, the ironing portion 20 is detached from the stand portion 24 and ironing is performed. At this time, since the power supply unit 31 of the ironing unit 20 is disconnected from the commercial power supply 23, power is not supplied and the output voltage of the power supply unit 31 is zero.

However, the power storage unit 32 is connected to the iron unit 2.
