Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless iron for preheating when an iron part is placed on a stand part and the heater part built in the base part of the iron part is heated by supplying electric power from the stand part. It is about.

[0002]

2. Description of the Related Art Conventionally, a cordless iron of this type has been proposed as shown in FIGS. 6 and 7, and its configuration will be described below.

As shown in the figure, when the iron part 1 is placed on the stand part 2, a heater part 4 for heating the base part 3 of the iron part 1 is provided on both the iron part 1 and the stand part 2. It is connected via P1, P4 and P5, P6 to the heater control unit 5 provided in the stand unit 2, and electric power is supplied to the heater unit 4 from the commercial power supply 6 to heat it.

The temperature detecting section 7 provided in the ironing section 1 detects the temperature of the base section 3 of the ironing section 1 and sends the signal to the temperature signal transmitting section 8. The temperature signal transmission unit 8 converts the output signal of the temperature detection unit 7 into a pulse voltage and outputs it to the electrode P2.

This is because when the iron part 1 is placed on the stand part 2, the temperature signal is transmitted from the iron part 1 to the stand part 2 by the contact between the electrode P2 of the iron part 1 and the electrode P3 of the stand part 2. Yes, but at this time the electrode part P
This is because a large current and voltage are applied between P2 and P3 to destroy the insulating film generated between the electrodes and to enable stable signal transmission without electrode contact failure.

In this way, the temperature pulse signal input to the stand unit 2 via the electrodes P2 and P3 is detected by the temperature signal detecting unit 9
Is detected by the control unit 10, the control unit 10 determines whether the temperature is higher or lower than a set temperature which is an input signal from the setting unit 11, and outputs the result to the heater control unit 5, and the heater control unit 5 uses the commercial power source. The voltage from 6 is turned on and off, the power supply to the heater section 4 of the iron section 1 is controlled through the electrode P4 of the stand section 2 and the electrode P1 of the iron section, and the temperature is controlled.

Further, the ironing part 1 is provided with a display part 12 and a notifying part 13, and when the ironing part 1 is detached from the stand part 2 and the ironing part 1 is in use, the base temperature of the ironing part 1 is set to a temperature. When it is detected by the detection unit 7 that the base temperature is high and still usable, the display unit 12 is turned on, and when the base temperature is lowered and the iron unit 1 needs to be returned to the stand unit 2 to be heated by power supply, the display unit 12 Turn off 12
The notification unit 13 is made to sound to notify.

The second display unit 1 is also provided on the stand unit 2.
4. The second notification unit 15 is provided, and when the iron unit 1 is placed on the stand unit 2 and the setting unit 11 is driven to set the temperature, this temperature setting level is displayed on the second display unit 14. When it is displayed or when the base temperature of the ironing part 1 rises and reaches the set temperature level, the output of the temperature signal detection part 9 and the output of the setting part 11 are compared and detected by the control part 10 and can be used. Is displayed.

The second notification section 15 is a buzzer when the base temperature of the ironing section 1 reaches the set temperature as described above, and a sound when it is ready for use. Furthermore, when the iron unit 1 is placed on the stand unit 2 and the commercial power source 6 is continuously applied for a predetermined time or longer, the second notifying unit 15 considers that the user has forgotten to turn off the power source and notifies the user with a buzzer or the like. To do.

[0010]

However, in such a conventional structure, the usable display temperature level of the display section 12 of the iron section 1 is independent of the setting section 11 of the stand section 2 and is the base of the iron section 1. To detect and display the temperature,
There is a problem that the display error of the display unit 12 of the ironing unit 1 becomes large because the usable temperature range differs depending on whether the setting unit 11 of the stand unit 2 sets a high temperature or a low temperature. It was

Further, the ironing section 1 needs a notifying section 13 for detecting a decrease in the base temperature by the temperature detecting section 7 and notifying when the ironing section 1 needs to be placed on the stand section 2. Further, in the stand unit 2, the iron unit 1 is placed on the stand unit 2, and the base temperature is set to the setting unit 1.
The 2nd alerting | reporting part 15 alert | reported when the temperature set by 1 is reached is required, and two alerting | reporting parts are needed.
