Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam iron for smoothing wrinkles on clothes and the like.

[0002]

2. Description of the Related Art Conventionally, a steam iron capable of adjusting the amount of water supplied to a vaporization chamber is disclosed in, for example, Japanese Utility Model Publication No. 32-151.
As described in Japanese Patent Publication No. 90, etc., it is possible to spout steam in an amount suitable for clothing.

Further, there is also a steam iron in which a temperature controller for controlling the temperature of the base to an arbitrary temperature and a control valve rod of a nozzle for supplying water to the vaporizing chamber can be operated by one knob, for example, Jikkaku Sho-39-. No. 17297, etc., it is possible to supply and stop the water to the vaporization chamber in accordance with the temperature of the base adjusted by the temperature controller.

By combining these conventional techniques, it is possible to control the amount of water supplied to the vaporization chamber in accordance with the temperature of the base adjusted by the temperature controller. When turned off, the nozzle can be closed, the amount of water supplied can be increased as the temperature is raised, and the amount of steam ejected can be changed corresponding to the vaporization capacity of the base.

[0005]

However, in such a structure, the temperature set by the temperature controller and the temperature of the base may not always coincide with each other during ironing work. If mistaken, there was a problem that hot water that did not vaporize from the hanging surface of the base gushed to wet clothes, and that the gushed hot water caused a worker to get burned.

That is, if the temperature of the base is set to an arbitrary temperature when the ironing work is started, energization of the heater is started and the nozzle is opened in a state corresponding to the set temperature. Therefore, if you start using before the base reaches the set temperature, the water supplied to the vaporization chamber will exceed the vaporization capacity of the base that has not been heated to the predetermined temperature, and it will spout as hot water without vaporizing. .

Further, if the set temperature of the base is raised even during the ironing work, the amount of water supplied to the vaporizing chamber increases at the same time, and a similar state occurs, which may cause the risk of wetting clothes or getting burned.

[0008] Therefore, it is a first object of the present invention to obtain a safe steam iron which can be satisfactorily finished at a temperature and steam suitable for clothes to be ironed. The second purpose is to obtain a safe steam iron which can prevent danger if it is used incorrectly.

[0009]

In order to achieve the first object, the steam iron of the present invention includes a base heated by a heater, a vaporization chamber formed in the base, and a vaporization chamber supplied to the vaporization chamber. A tank for storing water, a water guiding section for supplying the water in the tank to the vaporization chamber, a heat responsive body attached to the base, and a vertically movable operation rod linked to the heat responsive body, One end is attached to the operating rod so as to face the water guiding portion, and in response to the operation of the heat responsive body, supply and stop of water from the water guiding portion to the vaporization chamber, and the amount of water supplied to the vaporization chamber. Is provided with a valve device for controlling the.

In order to achieve the second object, the steam iron of the present invention forms a predetermined amount of gap between the heat responsive body and the operating rod, and the vaporization chamber allows water to evaporate in the gap. The heat responsive body and the operating rod are set to work together when the temperature is reached.

[0011]

With the above structure, the steam iron of the present invention is capable of operating the valve device through the operating rod by displacing the heat responsive body as the temperature of the base rises. The amount of water supplied can be controlled according to the temperature of the base.

Therefore, when the temperature of the base is low and the vaporizing ability is small, the amount of water supplied is small. Allows steam to be ejected at a suitable temperature.

Further, a gap of a predetermined amount is formed between the heat responsive body and the operating rod, and when the vaporization chamber reaches the temperature at which water can be evaporated, the heat responsive body and the operating rod are linked to each other. With this setting, the water guiding portion can be kept closed until the vaporizing chamber is heated to the temperature at which water can be evaporated. Therefore, even if the base is set to a predetermined temperature, water will not be supplied to the vaporization chamber until the base reaches that temperature.
