Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric iron with improved visibility of a temperature indicator during ironing and when the iron body is self-supporting.

[0002]

2. Description of the Related Art In a conventional electric iron of this type, a substrate having an SCR attached thereto is arranged in a handle as disclosed in Japanese Utility Model Publication No. 51-28480, for example. Advanced electronic circuits such as microcomputers have not been developed, and the circuit configuration is relatively simple.

Therefore, an indicator for displaying the temperature of the base body or the set temperature is not used, and a so-called energizing lamp simply indicating the energized state of the heater is provided below the handle.

However, in recent electric irons, a microcomputer is used to improve the usability, and accordingly, the temperature of the base body or the set temperature is displayed in a plurality of stages on a plurality of indicators. However, since the display is provided vertically on the side surface of the base close to the base body forming the handle body, the lighting state of the display cannot be confirmed unless the face is directed to the side during ironing. The operation was troublesome. In addition, the iron body is made to stand by itself at the time of a short rest or at the beginning of energization of the heater, but even at this time, the position of the user and the display is at right angles and the visibility is poor.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a plurality of temperature indicators can be read at the most recognizable position on the handle and the change in the displayed contents can be instantly read.

[0006]

In order to solve the above problems, the present invention provides a base body having a heater, a grip portion provided on the upper surface of the base body, and an overhang portion provided in front of the grip portion. And a temperature indicator mounted on the upper surface of the grip or overhanging portion, and a button provided on the outer surface of the handle and manually operated, the temperature indicator being in front of the button. And a plurality of light emitting diodes vertically arranged in the same direction as the longitudinal direction of the grip portion. The light emitting diodes are selectively displayed so as to display a desired temperature of the base body.

[0007]

[Operation] By vertically installing the temperature indicator in the same direction as the longitudinal direction of the grip, the temperature indicator and the face (field of view) of the user can be maintained both during ironing and when the iron body is free-standing. Since they face each other, the display can be instantly confirmed at a natural position.

Further, the temperature indicator can effectively utilize the space in the longitudinal direction of the grip portion and can read the change of the displayed contents step by step.

The temperature indicator of the present invention may display either the present temperature of the base body or the set temperature.

[0022]

The temperature indicator is a button which is provided on the outer surface of the handle and is manually operated (for example, a spray button).
Since it is provided in front of the button, when the user operates the button, since the entire hand is located behind the button, the temperature indicator is not obstructed by the entire hand. Therefore, the display of the temperature indicator is easy to see. Further, conventionally, a dial type temperature indicator on the handle or a temperature indicator orthogonal to the longitudinal direction of the handle is easy to see the front display, but difficult to see the back display. On the other hand, since the temperature indicator of the present invention is composed of a plurality of light emitting diodes that are vertically arranged in the same direction as the longitudinal direction of the grip portion, the distance between the user and each light emitting diode is substantially constant. You can instantly check the display status with your natural vision. Further, since the longitudinal shape of the handle is used, no special storage space for vertically installing a plurality of light emitting diodes is required.

Further, it is not necessary to provide a special storage space for vertically installing a plurality of temperature indicators by utilizing the longitudinal shape of the handle.
