Abstract

PURPOSE:To obtain an iron having operation convenience by simplifying a temperature setting operation by providing a temperature control means to control the energizing of a heater, and setting the temperature position of steam by performing the pressing operation of a temperature setting means for fixed time or more. CONSTITUTION:The temperature setting position of the steam is set by performing the pressing operation of the temperature setting means 14 for the fixed time or more after inserting a power cord to a receptacle. In other words, a temperature setting position is located at a (disconnected) position in a state where the power cord is inserted to the receptacle, however, temperature setting is immediately performed at the position of the steam by performing the pressing operation of the temperature setting means for the fixed time or more. Thereby, it is possible to perform the temperature setting at the position of the steam with the highest working frequency without operating the temperature setting means for several times by a user, which not only enables the operation to be simplified but prevents a mis-operation performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steam iron for removing wrinkles from clothing and the like.

2. Description of the Related Art Conventionally, a steam iron in which power supply to a heater was controlled by an electronic circuit had a structure as shown in FIG.

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 setting changes sequentially from "Low", "Medium", "High", "Steam", and again to "Off", and the display means 3 indicates the temperature setting. It is designed to show.

Problems to be Solved by the Invention However, in general, steam irons are often used with the temperature set to the "steam" position, and the temperature setting means 4 must be operated many times to set the temperature to the "steam" position. It was inconvenient because I couldn't do it. In addition, if the user makes a mistake and operates the switch too many times, the switch returns to the "off" position, which causes the problem that the user must repeat the setting operation again.

This is due to the following reasons. That is, when the power cord 1 is plugged into an 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,
The most frequently used "steam" position has a surface temperature of 1.
Since it is 60°C to 200°C, it is usually 80°C to 200°C.
When adjusting in the range of degrees Celsius, it is on the high temperature side, so if they are arranged in order from low temperature to high temperature, they will be placed away from the "off" position. Therefore, several operations are required, which is inconvenient and prone to erroneous operations.

Therefore, an object of the present invention is to provide a steam iron that is easy to use by simplifying the temperature setting operation to the "steam" position.

Means for Solving the Problems And in order to achieve the above object, the present invention sets the temperature position of the "steam" by pressing the temperature setting means for a certain period of time or more after the power cord is plugged into an outlet. This is how you set it.

Function: The steam iron of the present invention has the above-mentioned configuration. When the power cord is plugged into an outlet, the temperature setting is set to the "off" position, or when the temperature setting means is pressed for a certain period of time or more, the "steam iron" is immediately turned off. The temperature is set at the position.

As a result, the user can now set the temperature in the most frequently used "steam" position without having to operate the temperature setting means over and over again, making operation not only extremely easy but also eliminating the possibility of incorrect operation. It is.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 10 is a base in which a heater 11 is embedded, and 12 is a handle provided above this base 10. 13 is a temperature control circuit that compares and processes the temperature set by the temperature setting means 14 and the output of the temperature sensor 15 attached to the base 10 using a microprocessor 16;
An electromagnetic switch 17 is provided which controls energization to the heater 11 based on this output. Reference numeral 18 is a display means consisting of an LED or the like that indicates the set temperature, and it shows each stage from "off", which does not energize the heater 11, to "high", where the base temperature is about 200 degrees Celsius, and "steam". Lights up and displays.

Here, to explain in detail the temperature setting means 14 mentioned above, the temperature setting means 14 is normally set to "low" and "low" every time it is operated.
This device changes the temperature setting from "medium", "high", "steam", and then again to "off", but if the temperature setting means is pressed for more than a certain period of time, the temperature is immediately set to the "steam" position. It is.

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

First, when the power cord is plugged into an outlet, the "off" position of the set temperature display means 18 lights up, but of course the heater 11 is not yet energized. Normally, when the user uses steam here, if the user presses the temperature setting means 14 for a certain period of time or more, the temperature is immediately set to the "steam" position, and the "steam" position is also lit on the display means 13 in the same way. Then, energization to the heater 11 is started,
The temperature of the base 10 begins to rise. Thereafter, the temperature control circuit 13 detects the temperature of the base 10 based on the output of the temperature sensor 15, and maintains the temperature of the base 10 within the "steam" temperature range set by the temperature setting means 14, so that ironing can be done without any problem. It can be carried out.

Effects of the Invention As described above, the present invention allows the temperature position of the "steam J" to be set by pressing the temperature setting means for a certain period of time or more, so that the temperature of the "steam" which is usually used most frequently can be set. Settings are extremely simple and convenient, and erroneous operations can be prevented.
