Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) The present invention relates to a steam iron.

(Prior art) Generally, a steam iron has a vaporization chamber formed on the top surface of a base containing a built-in heating element, water in a water storage tank is dripped into this vaporization chamber via a valve, and the steam generated here is vaporized. The steam is ejected from a steam outlet in the base that communicates with the chamber.

The heating element is usually set to have a capacity of 600 to 800W. This capacity is used to maintain the base surface at an appropriate temperature for ironing.
Suitable for use as a source of heat to vaporize water to generate steam. However, when used as a dry iron, the amount of heat required to vaporize the water is not required, so a sufficient ironing effect can be obtained even if the capacity is less than the above-mentioned capacity.

Therefore, it is conceivable to have a device in which the capacity of the heating element can be arbitrarily switched as needed. However, when using such an iron as a steam iron, first set the temperature controller on the base to the steam temperature, then change the heating element capacity switch to high capacity, and then
You can use it as a steam iron for the first time by opening the valve by operating the steam switching button. If the operation becomes complicated in this way, it is easy to make operational errors during use, and if
When used as a steam iron, if the base temperature is set to a temperature unsuitable for vaporizing water, or if the capacity of the heating element is set to a small capacity, there may not be enough heat to vaporize water. As a result, a problem arises in that water droplets that are not fully vaporized may be ejected from the hanging surface of the base.

Conventionally, for example, as shown in Japanese Utility Model Publication No. 39-17297, a single operating body has been used to open and close a valve that drips water into the vaporization chamber, and to adjust a temperature controller that controls the temperature of the base. However, it is not possible to switch the capacity of the heating element depending on whether it is used as "dry" or "steam".

(Problems to be solved by the invention) As mentioned above, the device that switches the capacity of the heating element requires not only opening/closing the valve and setting the temperature, but also switching the capacity of the heating element, which is cumbersome to operate. At the same time, operational errors are also likely to occur.

This invention attempts to solve the above-mentioned problems by consolidating the opening and closing of the valve, temperature adjustment of the base, and switching of the capacity of the heating element into a single operation, thereby eliminating the complexity of the operation and making it easier to operate. The purpose is to prevent mistakes.

[Structure of the idea]

(Means for Solving the Problems) The steam iron of the present invention includes a water storage tank provided on a base that has a heating element and is formed with a vaporizing chamber and a steam outlet communicating with the vaporizing chamber. A valve for controlling the inflow of water in the tank into the vaporization chamber, a temperature regulator for controlling the temperature of the base caused by the heating element, and a switch for switching the capacity of the heating element to large or small are provided,
The first, second, and third valves are in contact with the operating parts of these valves, temperature regulators, and switches, respectively.
A cam is provided which forms a cam surface and has an operating body, and the first, second and third cam surfaces of this cam set the temperature controller to an arbitrary set temperature when the valve is closed. , the switch is switched to the small capacity side, and when the valve is open, the temperature regulator is set to a temperature suitable for steam generation, and the switch is switched to the large capacity side.

Further, a vaporizing chamber 3 is formed on the upper surface of the base 1, and a steam outlet 4 is provided on the lower surface of the base 1 in communication with the vaporizing chamber 3. A lid plate 5 is attached to the upper surface of the vaporization chamber 3.

A cover 6 is attached to the base 1, and a handle bottom plate 7 which also serves as a heat shield is provided on the cover 6. A handle body 8 is watertightly connected to the handle bottom plate 7. Handle 10 on top of 8
is formed, and a water storage tank 9 is formed in the handle body 8, and a water inlet 11 is formed at the upper front surface of this water storage tank 9, and a water inlet cover 12 is attached to this water inlet 11 so as to be openable and closable. .

In addition, the vaporization chamber 3 is provided at the bottom of the water storage tank 9.
A dripping valve 13 facing the water tank 9 is attached to the valve 13, and a valve rod 14 as a valve operation part that penetrates the water storage tank 9 is provided to be movable up and down. It is always energized in the upward direction.

Further, a temperature regulator 16 is attached to the base 1 to control the temperature of the base 1 by the heating element 2, and the movable part of the temperature regulator 16 is isolated from the water storage tank 9 in a watertight manner within the handle body 8. The lower end of an operating rod 17 serving as a temperature regulator operating section is connected to the lower end of the operating rod 17, which is provided so as to be able to move up and down through the space.

Further, a switch 18 is provided at the upper part of the handle body 8 to open and close the auxiliary heating element 2b to change the overall capacity of the heating element 2 to a large or small capacity.

As shown in FIG. 2, a main heating element 2a is connected to the power source via a temperature regulator 16, and an auxiliary heating element 2b is connected to the main heating element 2a in parallel with the switch 1.
8.

Further, as shown in FIG. 1, a support plate 20 is attached to the upper part of the handle body 8, a cam 21 is rotatably mounted on this support plate 20, and the valve rod is mounted on the lower surface of this cam 21. A first cam surface 22 that contacts the upper end of the switch 14 and a second cam surface 23 that contacts the upper end of the operating rod 17 are formed, and the operating piece 19 of the switch 18 contacts the upper surface of the cam 21. The third
A cam surface 24 is formed. A lever 25 as an operating body extends from the cam 21, and an instruction knob 26 is attached to the front end of the lever 25. Also, a cam 2 is attached to the handle body 8.
A cap 27 is attached to cover one part, and a display plate 28 is affixed to the upper surface of the cap 27 so as to face the rotating part of the indicator knob 26.

Then, when the lever 25 is rotated, the cam 21 rotates together, and the valve rod 14 moves up and down in response to the change in height of the first cam surface 22, opening and closing the valve 13 to change the steam state and dry state. At the same time as changing the state, the operating rod 17 moves up and down in response to the change in height of the second cam surface 23, actuating the temperature regulator 16, and controlling the heating elements 2, that is, the main heating element 2a and the auxiliary heating element 2b. The heating temperature of the base 1 is adjusted, and the operating piece 19 of the switch 18 moves up and down in response to changes in the height of the third cam surface 24.
By turning on and off the power supply to the auxiliary heating element 2b, the capacity of the heating element 2 as a whole can be switched between two levels: large and small.

The first, second, and third cam surfaces 22, 23, and 24 of the cam 21 are formed in the following relationship. First, move the valve rod 14 up and down to open the valve 1.
The first cam surface 22 that opens and closes the valve rod 1

A temperature regulator 16 is formed in the steam region of the first cam surface 21 to set the temperature to a temperature suitable for generating steam (approximately 160 to 190° C.). Furthermore, the third cam surface 24, which moves the operating piece 19 of the switch 18 up and down to turn on and off the energization to the auxiliary heating element 2b, is connected to the auxiliary heating element 2b within the steam area of the first cam surface 22. The energization is turned on in the dry region and turned off in the dry region. And, on the display board 28,
A temperature scale and "dry" and "steam" are displayed in correspondence with the control state by the cam 21. In this manner, the first, second, and third cam surfaces 22, 23, and 24 of the cam 21 adjust the temperature regulator 16 to an arbitrary set temperature when the valve 13 is closed, and the switch 18 When the valve 13 is switched to the small capacity side and the valve 13 is open, the temperature regulator 16 is set to a temperature suitable for steam generation, and the switch 18 is switched to the large capacity side.

In such a configuration, when the lever 25 is rotated by the indicator knob 26 and set at an arbitrary temperature scale position in the dry region, the valve 13 is closed, the power supply to the auxiliary heating element 2b is turned off, and the heating element 2 is turned off. Although the capacity of only the main heating element 2a is small, a sufficient ironing effect can be obtained as a dry iron.
Economical.

Next, when the lever 25 is set in the steam region, the valve 13 is opened, the temperature regulator 16 is set to a temperature suitable for steam generation, the auxiliary heating element 2b is energized, and the steam is generated. Automatically switches to the temperature and heating element capacity required for generation.

In the above embodiment, the heating element is provided with a main heating element and an auxiliary heating element, and the capacity is switched by turning on and off the auxiliary heating element, but as shown in FIG. body 2 is connected via a temperature regulator 16 and a switch 18, and this switch 18
If a half-wave rectifying element 29 is connected in parallel with the heating element 2, the capacity can be switched even with one heating element 2.

In addition, the cam operating body is not limited to levers.
It can also be a dial. Moreover, a separate tank may be used as the water storage tank.

[Effect of idea]

According to the present invention, by operating one operating body,
You can open and close the valve to switch between dry iron and steam iron, operate the temperature controller to adjust the temperature of the base, and flip the switch to change the heating element capacity.For example, you can change the operating body to steam iron. When set, the temperature of the base can be set to a temperature suitable for steaming at the same time as the valve is opened, and the heating element can be switched to a large capacity, making it possible to use it as a steam iron. Not only can the operation be made easier, but also water can be prevented from being splashed from the hanging surface due to operational errors.
