Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a steam iron equipped with a removable tank for use in general households.

Structure of the conventional example and its problems Conventionally, this type of steam iron
As shown in Publication No. 4497, it was thought that a tank could be detachably attached to the iron body to facilitate water supply and drainage work, but from the perspective of the finishing effect on fabrics, it was thought that it would be possible to simply switch between dry and steam. The steam ejection state cannot be changed arbitrarily according to the condition of the fabric, which makes it difficult to work.In addition, since the tank is detachable from the iron body, it is difficult to maintain airtightness when connecting the tank to the base side. However, there were drawbacks such as a complicated structure.

Purpose of the invention The present invention solves the above-mentioned drawbacks of the conventional steam iron, and by adding a steam concentration/dispersion switching device to a removable tank steam iron, it improves usability such as water supply and drainage, improves the finishing effect, and improves the switching system. The purpose of the present invention is to simplify the liquid-tight structure of a valve device and to rationally link it with an operating rod provided on the side of a tank that is detachably attached to an iron body.

Structure of the Invention In order to achieve the above object, the present invention includes a base forming a vaporization chamber, a tank detachably attached above the base, and a bottom surface of the base for discharging the steam generated in the vaporization chamber. a steam passage leading to the concentration hole and the distribution hole, respectively;
The switching valve device includes a switching valve device that opens and closes a switching port formed in the steam passage, and an operation rod that is provided in the tank facing the switching valve device so as to be movable up and down, and the switching valve device has a cylindrical upper portion. The seal structure is simplified by surrounding the seal with a backing and protruding from the upper surface of the base.

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

In the figure, 1 is a base with a built-in heater 2 and a vaporization chamber 3; 4 is a first steam passageway for introducing the steam generated in the vaporization chamber 3 into a concentration hole 4a provided on the bottom surface of the base 1; 5 is a vaporization A second steam passage 6 is installed on the base 1 to guide the steam generated in the chamber 3 to the dispersion hole 5b provided on the lower surface of the base 1 through the switching port 5a. The cover 7, which has a recess 6a on the side, is a flexible connecting member that protrudes upward from the recess 6a and is attached to the vaporization chamber 3. It is made of a heat-resistant material such as silicone rubber, and has a is provided with an insertion hole 7a.

Reference numeral 8 denotes a cylindrical switching valve backing formed integrally with this connecting member 7, whose lower part faces the switching port 5a, and which liquid-tightly surrounds the upper part of the switching valve device 9 protruding from the recess 6a. A flange 8a provided integrally with the member 7 at its lower part is pressed and fixed onto the base 1 by the recess 6a of the cover 6.

The switching valve device 9 is always urged upward by the elastic force of the switching valve backing 8, and acts in a direction to close the switching port 5a from below.

Reference numeral 10 denotes a heat shield plate attached to the cover 6, which has an opening 10a facing the recess 6a, and whose peripheral edge is an inclined surface expanding upward.

11 is a handle installed on the cover 6, 12 is a tank detachably installed on the iron body A, and a nozzle portion 13 connected to the vaporizing chamber 3 via a connecting member 7 is provided at the bottom.

Reference numeral 14 denotes a nozzle member to which this nozzle portion 13 is fixed, and is removably attached to the tank 12 via an O-ring 15, and is provided protruding toward the base 1 side so as to surround the nozzle portion 13 and the switching valve device 7, and is provided with an opening 10a. Rib 14a that fits into
is formed.

Reference numeral 16 denotes an opening/closing rod provided in the tank 12 so as to be able to move up and down, and is constantly urged upward by a spring 16a.
With the lower end facing the nozzle part 13, the nozzle part 13 is opened by vertically moving the steam button 16b on the upper part of the tank 12.
Open and close.

Reference numeral 17 denotes an operating frame that is movable up and down through a guide portion 18 that protrudes upward in the tank 12, and a spring 18a.
The lower end thereof protrudes from the tank 12 and faces the switching valve device 7.

The operating frame 17 moves up and down in conjunction with a cam 16c fixed to the opening/closing rod 16, which rotates while moving up and down when the steam button 16b is pressed.

Numeral 19 is a locking portion provided on the upper rear surface of the tank 12 protruding toward the handle 11 side, and 20 is a locking portion provided on the handle 11 opposite to this locking portion 19.
With a locking device provided on the side, the tank 1 is always held by a spring 20a.
2 side, and engages with the locking portion 19 to lock the tank 1.
2 is held attached to the iron main body A.

In the above structure Ji, when the tank 12 is removed from the iron body, the locking device 20 is slid in the direction of arrow A to release the engagement with the locking portion 19.

Then, the tank 12 can be removed in the direction of the arrow.

Water supply or drainage work to the tank 12 can be performed in a state separated from the iron main body A, and during this time, the heating or cooling of the iron A main body can be performed simultaneously in parallel with the water supply and drainage work of the tank 12.

Also, when attaching the tank 12 to the iron body A,
By operating the tank 12 in the direction of arrow C and fitting the rib 14a into the opening 10a using the inclined surface of the heat shield plate 10 as a guide, the nozzle part 13 is connected to the connecting member 7 and the vaporization chamber 3 is connected.
The operating frame 17 is also disposed with its lower end facing above the switching valve device 9 .

By engaging the locking device 20 with the locking portion 19, the iron main body A is kept attached.

In addition, in the steam operation, the water in the tank 12 is
3, becomes steam in the vaporization chamber 3, passes through the first steam passage 4, and is discharged from the concentration hole 4a.

Then, when the operation frame 17 is lowered via the cam 16c by operating the steam button 16b and the switching valve device 9 is pushed down to open the switching port 5a, the steam is also guided to the second steam passage 5, and is guided through the dispersion hole. 5b, the steam can be ejected over a wide range of the lower surface of the base 1, and the switching can be done as desired depending on the nature, characteristics, and circumstances of the fabric to be finished.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the upper part of the switching valve device disposed at the switching port of the steam passage is surrounded by a cylindrical backing and is provided to protrude toward the upper surface of the base.
It is easy to link with the operation frame provided on the removable tank, and since the backing is cylindrical and a part of it tightly surrounds the switching valve device, the tank can be removed and the switching valve device can be opened easily. Even if the upper part is exposed to the surface and an external force is applied, the elastic force of the backing flexibly responds to the application, making it possible to always maintain the desired setting state.

Therefore, with a steam iron with a removable tank, you can take full advantage of the feature that you can iron by inserting the front part of the base into, for example, a cuff, etc., with the tank removed. This is particularly effective in this type of iron, where irons are often used.
