Description

[Detailed explanation of the idea] (1) Technical field of invention The present invention relates to a steam iron.

(2) Prior art and its problems Generally, a steam iron has a vaporizing chamber formed in the base, water is dripped into this vaporizing chamber from a water storage tank by a drip nozzle, and the steam generated here is communicated to the vaporizing chamber. It is made to eject from the spout of the base.

Then, during use, after adjusting the temperature of the base to a temperature suitable for steam generation using the adjustment dial of the temperature controller, the dripping nozzle is opened to allow water to drip into the vaporization chamber of the base to generate steam. ing. In this case, a base temperature adjustment operation and a water dripping operation are required.

Therefore, a device has been proposed in which when the adjustment dial is set to steam, temperature control and opening/closing of the dripping nozzle are performed simultaneously using a cam that is linked to the dial.

However, according to the conventional method, when operating the operating part that performs temperature control and opening/closing of the dripping nozzle at the same time, the dry ironing area and the steam ironing area are formed continuously. It is possible to move smoothly into the area without any resistance, and there is a risk that even a small amount of erroneous operation may cause the device to be set to an undesired state. That is, it is difficult to align the operating section near the boundary between the dry ironing area and the steam ironing area.

In addition, when you finish ironing and store the iron, even if you intend to store it in a dry state with the operating section aligned, it easily switches to a steam state, which may cause the base to corrode and make it unusable. .
