Description

DETAILED DESCRIPTION OF THE INVENTION A field of industrial application concerns cordless irons in which the power cord is removed from the iron body.

Conventional Structures and Problems Currently, the most common electric irons have a built-in heater that is powered by a power cord attached to the iron body. However, these electric irons have disadvantages in that the power cord led out from the main body gets in the way during ironing work, and the operating range of the iron is restricted by the length of the power cord. Therefore, the iron body has only a power supply terminal that is connected to the heater without leading out the power cord, and a power supply terminal that connects to the power supply terminal and supplies power when the iron body is placed. A device has been developed in which a stand is provided separately and the iron body is separated from the stand during ironing work. Some of these cordless irons are equipped with a steam generator and a heat storage material that can store enough heat to withstand steam generation, so that they can be used as steam irons. The steam iron is 1'1
How to place the iron body on the stand from the iron side If you do not turn off the steam by operating the steam button or steam lever when placing the steamer, not only will the steam continue to come out and water will be wasted, but the table will become wet due to condensation from the steam.

There is a problem that the amount of heat is taken away by the steam generation, which increases the heat storage time and the waiting time.
To provide a cordless iron which can prevent unnecessary spouting of steam by automatically stopping steam generation when an iron body is placed on a mounting table.

Structure of the Invention In order to achieve this object, the cordless iron of the present invention is provided with an electric actuator that operates an opening/closing rod in the iron body to control the supply of water, and the iron body is placed on a mounting table. Electric actuator turns on when power is supplied
L, the steam generation is stopped.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an iron main body, and a storage chamber 4 for accommodating a heat storage material 3 is formed on the upper surface of a base 2, and a vaporization chamber 5 is formed approximately at the center of the storage chamber 4. Storage room 4
Heat transfer fins 6 are formed inside to improve heat conduction between the heat storage material 3 and the base 2. The storage chamber 4 and the vaporization chamber 5 are covered by a base lid 7 to form respective chambers. Further, a heating element 8 for heating the base 2 and the heat storage material 3 is buried in the base 2. water tank 9
Water 1Q for steam generation is stored in the tank, and when the steam button 11 is operated, the opening/closing rod 12 is moved upward to open and close the water supply hole 13, and water is dripped into the vaporization chamber 6. Further, the opening/closing rod 12 is also linked with an electric actuator 14 made of a lunoid, and the electric actuator 14 is
When N is pressed, the opening/closing rod 12 is forcibly moved downward and the water supply hole 1 is closed.
3 is closed. Steam generated in the vaporization chamber 5 is ejected from the ejection hole 16 communicating with the vaporization chamber 5 to the bottom surface of the base 2. The temperature control dial 16 is connected to the temperature control device 1a (second
(shown in the figure) so that the temperature of the base 2 can be adjusted.

The heating element 8 is electrically connected to the power supply terminal 18 via the temperature control device 17. Further, a cover 19 is attached to the base 2 to cover the upper surface thereof, and a locking part 20 is fixed to the upper part of the cover 19.

Reference numeral 21 denotes a mounting table, on which the iron main body 1 can be placed in a substantially horizontal state.

When the iron main body 1 is placed, the power terminal 24 which is electrically connected to the power cord 23 is connected to the power supply terminal 18 to supply power into the iron main body 1. Still power! A spring 25 is attached to the connector 24 to bring it into elastic contact with the power supply terminal 18.

FIG. 2 is an electrical circuit diagram of this embodiment, in which the power supply terminal 24 is electrically connected to the power supply 26, the heating element 8 is electrically connected to the power supply terminal 18 via the temperature control device 17, and the electric actuator 14 is parallel to the power supply terminal 18. It is connected to the.

The operation of the configuration as described above will be explained next.

First, the iron body 1 is placed on the mounting table 21, the temperature control dial 16 is set to the steam scale, and the power cord 23 is connected to the power source.The electric actuator 14 is turned on and the opening/closing rod 12 is closed, and at the same time heat is generated. When the body 8 begins to generate heat, the base 2 is heated to a predetermined temperature, and the temperature is maintained by the temperature control device 17. At this time, the storage chamber 4 and the heat transfer fins 6 are also heated, and heat is stored in the heat storage system 3.

When ironing is performed, the iron main body 1 is separated from the mounting table 21, and the work can be done without being hindered by the power cord due to the amount of heat stored in the heat storage material 3. To generate steam, operate the steam button 11 to open the opening/closing rod 12, and the water 10 in the water tank 9 will drip into the vaporization chamber 6 through the water supply hole 13, and steam will be generated from the spout hole 15. Emit steam.

Now, when the iron main body 1 is placed on the mounting table 21 again in the middle of ironing, the power supply terminal 18 and the power supply terminal 24 are connected and the heating element 8 is heated and supplies heat to the heat storage material 3. At the same time, the electric actuator 14 is also turned on, and even if the opening/closing rod 12 is in the open state, it is forcibly opened to stop the water dripping and the steam to stop. Therefore, the mounting plate 22 will not get wet due to steam condensation.
Heat can be efficiently stored in the heat storage material 3 without losing excess heat due to steam generation.

Next, in order to iron again, iron body 1
When the electric actuator 14 is separated from the mounting table 21, the electric actuator 14 becomes 0.
FFL, the opening/closing rod 12 returns to the open state and blows out steam.

As shown in 2, when the iron main body 1 is placed on the mounting table 21, the electric actuator 14 is turned ON [, and opened/closed 4J12.
is forcibly closed, and when it is disconnected, it turns OFF and the opening/closing rod 12
By opening the steam button 11, the steam can be ejected and stopped automatically without having to operate the steam button 11 each time.

In this embodiment, the electric actuator 14 is made of a solenoid, but it may be of the type in which a heater is wound around a bimetal, for example.

In short, the same effect can be obtained as long as the opening/closing rod 12 can be operated electrically.

Effects of the Invention As described above, the present invention includes an electric actuator that controls the supply of water by operating an opening/closing rod inside the iron body, so that when the iron body is placed, steam is automatically generated. It can be stopped, preventing unnecessary steam from blowing out without having to manually stop the steam each time.
To provide a cordless iron that can efficiently supply electricity to the iron body without causing dew condensation on a mounting table due to steam.
