Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a steam iron for general household use.

Prior Art A steam iron using a conventional electronic control circuit has a structure as shown in Fig. 3.

That is, when the power cord 1 is plugged into an outlet, the heater 2 is not energized, and the display means 3 indicating the temperature setting position is illuminated at the "off" position. Each time the user operates the temperature setting means 4, the temperature is set to "low", "medium", "high",
The display changes to "steam" and then to "off" in sequence, which is indicated by the display means 3.

Problems that the invention aims to solve However, in general, steam irons use "steam"
It is inconvenient that the "steam" position cannot be set unless the temperature setting means 4 is operated many times. If it is turned off too much, it will return to the "off" position, causing problems such as having to repeat the setting operation from the beginning.

This is due to the following reasons.

That is, when the power cord 1 is plugged into the outlet, the temperature setting is always in the "off" position, and the user needs to set the temperature using the temperature setting means 4 before starting ironing work. And since the most frequently used "steam" position has a surface temperature of 160°C to 200°C, it is usually 80°C to 200°C.
Adjustment within the temperature range of ℃ requires high temperature measurement, so if it is placed in order from low temperature to high temperature, it will be placed far from the ``off'' position, requiring several degrees of operation, which is inconvenient and prone to erroneous operation.

Therefore, the present invention simplifies the temperature setting operation for the "steam" position and improves usability.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to set the base temperature to "steam" by operating the temperature setting means once after plugging the power cord into the outlet. It has been made possible.

Effect The effect of this technical means is as follows.
In other words, when the power cord is plugged into an outlet, the temperature setting is in the "off" position, but
When the temperature setting means is operated once, the temperature is immediately set to the "steam" position.

As a result, the user does not have to operate the temperature setting means over and over again, and the most frequently used "steam"
The temperature can be set at any position, which not only makes operation very easy, but also eliminates erroneous operations.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 5 is a base in which a heater 6 is embedded, and 7 is a handle provided above this base 5. 8, a microcomputer 11 receives the temperature set by the temperature setting means 9 and the output of the temperature sensor 10 attached to the base 5.
The electromagnetic switch 12 controls the energization to the heater 6 based on this output.
It is equipped with Reference numeral 13 denotes a display means consisting of an LED or the like, which indicates the set temperature, and lights up to indicate each stage from "off", which does not energize the heater 6, to "high", when the base temperature is about 200 degrees Celsius. . 14
is a power cord that supplies power to the heater 6, temperature control circuit 8, and the like.

Here, to explain the temperature setting means 9 in detail, the temperature setting means 9 first sets the temperature at the "steam" position in the first operation, and then changes the temperature to "low", "medium", "high" and then on each subsequent operation. "Off" and "Steam" again
It changes the temperature setting.

Furthermore, as shown in FIG. 3, the ``off'' and ``steam'' positions may be placed apart for display reasons.
In short, it is sufficient to set the temperature at the "steam" position in the first operation, and the order of temperature settings thereafter is not particularly critical.

Next, the operation of the configuration of this embodiment will be explained.

First, when the power cord 14 is plugged into an outlet, the "off" position of the set temperature display means 13 lights up, but of course the heater 6 is not energized yet. Here, in order to use steam, the user simply operates the temperature setting means 9 once, and the temperature setting immediately changes to "steam", and similarly the display means 1
3 also lights up in the "steam" position. Then, power supply to the heater 6 is started, and the temperature of the base 5 starts to rise. From then on, the temperature control circuit 8 detects the temperature of the base 5 based on the output of the temperature sensor 10,
The temperature of the base 5 is maintained within the "steam" temperature range set by the temperature setting means 9, and ironing can be performed without any trouble.

Effects of the Invention As described above, the present invention enables switching from the "off" state to the "steam" state by operating the temperature setting means once.
By setting the base temperature to "steam" and displaying on the display means that the base temperature is set to "steam", it is possible to set the base temperature to "steam", which is the most frequently used setting for steam irons. , can be easily and conveniently performed with a single operation using the temperature setting means, and
Since there is no need to go through other set temperatures, erroneous operations can be reliably prevented.
