DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless iron used for preheating by heating a heater incorporated in a base of an iron by supplying power from the stand when the iron is placed on the stand. Things.

[0002]

2. Description of the Related Art Conventionally, this kind of cordless iron has
The one shown in FIGS. 14 and 15 has been proposed. That is, when the iron part 1 is placed on the stand part 2,
The heater unit 4 for heating the base unit 3 of the iron unit 1 includes electrode units P1 and P provided on both the iron unit 1 and the stand unit 2.
The heater 4 is connected to the heater control unit 5 provided in the stand unit 2 via P4, P5, and P6, and is supplied with electric power from the commercial power supply 6 to be heated.

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

This is because when the iron 1 is placed on the stand 2, the temperature signal is transmitted from the iron 1 to the stand 2 by contact between the electrode P2 of the iron 1 and the electrode P3 of the stand 2. However, at this time, a large current and voltage are applied between the electrode portions P2 and P3 to break the insulating film formed between the electrodes, thereby enabling stable signal transmission without electrode contact failure.

Thus, the temperature pulse signal input to the stand 2 via the electrodes P2 and P3 is
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. 6 is turned on and off to control the power supply to the heater unit 4 of the iron unit 1 via the electrode P4 of the stand unit 2 and the electrode P1 of the iron unit, thereby performing temperature control.

[0006] The iron unit 1 includes a display unit 12 and a notification unit 13. When the iron unit 1 is detached from the stand unit 2 and the iron unit 1 is in use, the iron unit 1 is used.
It is necessary to detect the base temperature by the temperature detecting section 7 and turn on the display section 12 when the base temperature is high and the apparatus can still be used, to lower the base temperature and return the iron section 1 to the stand section 2 to heat the power supply. In this case, the display unit 12 is turned off, and the notification unit 13 sounds to notify the user.

The second display unit 1 is also provided on the stand unit 2.
4. When the temperature is set by driving the setting unit 11 by placing the iron unit 1 on the stand unit 2 and displaying the temperature setting level on the second display unit 14, the second notification unit 15 is provided. Or when the base temperature of the ironing unit 1 rises and reaches the set temperature level, the control unit 10 compares and detects the output of the temperature signal detecting unit 9 and the output of the setting unit 11 to enable use. This is to indicate that it has become.

[0008] The second notification section 15 notifies the user by using a buzzer when the base temperature of the iron section 1 reaches the set temperature, and notifies the user of the fact that the iron section 1 becomes usable. Further, when the commercial power supply 6 is continuously applied for a predetermined time or more with the iron unit 1 placed on the stand unit 2 for a predetermined time or more, the second notification unit 15 notifies that the power supply has been forgotten to be turned off by a buzzer or the like.

[0009]

However, in such a structure, the usable display temperature level of the display unit 12 of the ironing unit 1 is controlled independently of the setting unit 11 of the stand unit 2. To detect and display temperature,
Since a usable temperature range is different between a case where the temperature is set to a high temperature by the setting unit 11 of the stand unit 2 and a case where the temperature is set to a low temperature, a display error of the display unit 12 of the iron unit 1 is increased.

Further, the ironing unit 1 needs a notifying unit 13 for detecting a decrease in the base temperature by the temperature detecting unit 7 and notifying when it is necessary to mount the ironing unit 1 on the stand unit 2. Further, the iron part 1 is mounted on the stand part 2, and the base temperature is set on the setting part 1.
There is a problem that the second notification unit 15 for notifying when the temperature set in 1 is reached is required, and two sets of notification units are required.

The present invention solves the above-mentioned problems, and
The setting signal set in the stand section, that is, not only the temperature setting level but also various setting signals such as steam setting or mist generation setting are sent to the ironing section, and a display or notification according to the setting level is performed. It is an object of the present invention to provide an inexpensive cordless iron with excellent performance by sending a temperature signal from a unit to a stand unit and controlling the temperature by the stand unit.
