Description

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

Prior Art Conventionally, this type of steam iron has been constructed as shown in Fig. 4. That is, a base 2 having a heater 1, a vaporization chamber 3 formed in a part of this base 2, a tank 5 for storing water 4 to be supplied to this vaporization chamber 3, and a space between this tank 5 and the vaporization chamber 3. The opening/closing rod 7 is configured to have a nozzle section 6 configured as shown in FIG. When the nozzle section 6 was operated and the water channel of the nozzle section 6 was opened, the water 4 in the tank 5 was dripped into the vaporization chamber 3 by gravity, and steam was generated.

Problems to be Solved by the Invention However, with such a structure, the steam button 8 is operated to open the waterway of the nozzle part 6 to generate steam, but the vertical stroke of the steam button 8 is It was large and difficult to use. Further, it is difficult for the user to determine whether the water channel of the nozzle portion 6 is open or closed, that is, whether the steam state is in the steam stopped state, which is inconvenient.

Therefore, the present invention simplifies the operation of the steam button and displays the status of the steam selected by the steam button in an easy-to-understand manner.

Means for Solving the Problems In order to solve the above-mentioned conventional drawbacks, the present invention provides a base that is heated by a heater and has a vaporizing chamber formed in a part thereof, a handle attached to the base, and a handle attached to the handle side. A tank is provided to store water to be supplied to the vaporization chamber, a water supply device has a pump function to suck the water in this tank through a water suction pipe and forcefully send it to the vaporization chamber from a discharge pipe, and a part of the handle is A steam button with a switch function attached thereto, a water supply control circuit that sequentially increases the capacity of the water supply device each time the steam button is pressed, and a display device that displays the capacity status of the water supply device. It is something.

Function In the above configuration, the water supply control circuit sequentially increases the capacity of the water supply device each time one steam button is pressed to vary the amount of water supplied to the vaporization chamber, for example, switching between normal steam and increased steam. will be done.

Further, the current capacity of the water supply device, that is, the amount of steam ejected, is displayed on the display device.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 11 is a base having a heater 12, and 13 is this base 11.
A vaporization chamber 14 formed in a part of the base 11
It is a handle installed above. 15 is a temperature setting means, and 16 is a display means such as an LED that indicates the set temperature. 17 is a tank for storing water, 18
1 is a water supply device for feeding the water in the tank 17 to the vaporization chamber 13, 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; 20
is the discharge pipe. Reference numeral 21 denotes a steam selection button constituted by a small switch, the contact of which is normally open, but which closes when pressed by the user. 22 is a water supply control circuit composed of a plurality of electronic components for controlling the operation of the water supply device 18, and each time the steam selection button 21 is pressed, the states of normal steam, increased steam, and steam stop are changed. The water supply device 18 is controlled so as to be repeated in sequence. 23 is a steam display device composed of an LED or the like to indicate the steam status set with the steam selection button 21. It lights up continuously during normal steaming, blinks when increasing steam, and turns off when steam is stopped. The parts can display three types of steam status.

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

First, the temperature setting means 15 selects a temperature of about 180 DEG C. to 200 DEG C., which is a temperature at which steam can be generated. As a result, the heater 12 starts to be energized, and the base 11
temperature rises and steam becomes usable. If the user wants to use normal steam, he or she presses the steam selection button 21 once, and the water supply control circuit 22 activates the water supply device 18 to start spouting steam. Further, the steam display device 23 lights up to inform the user that the normal steam setting is set. 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 selection button 21 again, and the water supply control circuit 22 operates the water supply device 18 so that the increased amount of steam is spouted, and the steam display device 23 changes from continuous lighting to blinking to indicate that the increased amount of steam has been set. When the steam is no longer needed, the water supply device 18 is stopped by pressing the steam selection button 21 again, and the steam display device 23 is also turned off, indicating that the steam has stopped.

Further, as another embodiment of the steam display device according to the present invention, as shown in FIG.
If the increased steam and steam stopped states are configured with separate display members 23a, 23b, and 23c,
Furthermore, the display becomes easier to see and understand.

Effects of the Invention As described above, the present invention has a steam display device that shows the steam status arbitrarily set with the steam selection button, such as normal steam, increased steam, steam stop, etc. To realize an easy-to-use steam iron that can easily check the steam condition and prevent misuse.
