Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a household steam iron for removing wrinkles from clothing and the like.

2. Prior Art Conventionally, this type of steam iron is disclosed in Japanese Patent Application Laid-open No. 59-16, for example.
The configuration was as shown in the No. 8892 publication, and specifically, the configuration was as shown in FIG.

That is, a tank 3 is placed on a base 2 having a vaporization chamber 1, and the water in this tank 3 drips into the vaporization chamber 1 from a nozzle section 4 provided at the bottom of the tank 3 to generate steam. 5 opens and closes the nozzle part 4 via the opening/closing rod 6. In addition to such normal steam, it is possible to temporarily supply a large amount of steam. Its structure is to increase the amount of steam by temporarily sending a large amount of water to the vaporization chamber 1 using a pump device 9 having a suction channel 7 that opens at the bottom of the tank 3 and a discharge channel 8 that opens into the vaporization chamber 1. It can be operated independently from the steam button 5! , a quantity increasing button 10 was provided.

Problems to be Solved by the Invention However, with this type of structure, there is a steam button for normal steam control at the upper front of the iron body, and an increase button for sending a large amount of water to the vaporization chamber at each time. Because of the protruding lines, it was difficult to operate, inconvenient to use, and the structure was complicated.

Therefore, the present invention improves usability by allowing users to select regular steam and increased steam using a single steam button.

Means for Solving the ProblemsThe technical means of the present invention for solving the above problems is a water supply device that supplies water in the tank to the vaporization chamber, and a steam button provided at the upper front part of the iron body. and a water supply control means that processes the signal from the steam button and controls the capacity of the water supply device.

With this configuration, the water supply control means controls the capacity of the water supply device so that the normal amount of steam is ejected when the steam button is pressed for less than a certain period of time, and also controls the ability of the water supply device so that the normal amount of steam is ejected when the steam button is pressed for more than a certain period of time. increases the capacity of the water supply system to emit increased amounts of steam. This allows you to easily select between normal steam and increased steam with a single steam button, and this is possible using electrical signal processing, so the steam button does not need to stick out, making it much easier to operate. improves.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. 1 and 2, 11 is a base having a heater 12, 13 is a vaporization chamber formed in a part of the base 11, and 14 is a handle provided above the base 11.

15 is a temperature setting means, and 16 is an LE indicating the set temperature.
This is a display means consisting of D, etc. Reference numeral 17 denotes a tank for storing water, and a water supply device for conveying the water in the tank 17 to the vaporization chamber 13 during the day, and is constituted by a diaphragm pump using a motor, a solenoid pump, or the like.

19 is a water suction pipe connected to the water supply device 18, and 2o is a discharge pipe. Reference numeral 21 denotes a steam button composed of a small switch, the contact of which is normally open, but which closes when pressed by the user.

Reference numeral 22 denotes a water supply control means composed of a plurality of electronic components to control the operation of the water supply device 18, and if the steam button 21 is pressed for less than a certain period of time, the normal steam pressing operation is performed for more than a certain period of time. If so, the water supply device 18 is controlled so that an increased amount of steam is spouted.

In this case, the certain period of time is preferably about 1 second.

The water supply device 18 is controlled by changing the voltage applied to the water supply device 18 or by changing the on/off ratio of power supply.

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

First, the temperature setting means 15 selects a temperature of approximately 1800 to 200°C at which steam can be ejected.

As a result, the heater 12 starts to be energized, the temperature of the base 11 rises, and the steam becomes usable. Here, if the user uses normal steam, press the steam button 2.
If you press 1 for a certain period of time or less, that is, 1 second or less, which is a time that you do not notice, the normal steam state will be maintained from then on. Furthermore, when you need to increase the amount of steam, such as when ironing fibers that do not easily wrinkle, such as cotton or linen, or when floating wool, etc., press the steam button 21 for more than a certain period of time, that is, consciously for 1 second. If the pressing operation is carried out for a longer time than that, the water supply control means 22 will increase the capacity of the water supply device 18 and eject an increased amount of steam. Here, the increased steam state may be maintained until another operation is performed using the steam button 21, or
If a microcomputer or the like is used as the water supply control means 22, it is easy to enter the increased steam state only while the steam button 21 is pressed and automatically return to the normal steam state when the pressure is stopped. . Furthermore, although no particular mention was made of stopping the steam, a separate switch may be provided for this purpose, but the steam button 21 may also be used for this purpose.

Effects of the Invention As described above, in the present invention, with one steam button, normal steam and increased steam can be selected depending on the time when the steam button is pressed, thereby simplifying the configuration and saving base ratio. It is possible to realize a steam iron that is not only measurable but also easy to use.
