Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a steam iron for general household use.

BACKGROUND OF THE INVENTION Conventionally, this type of steam iron has had a construction as shown in FIG. That is, the vaporization chamber 2 is provided in the base 1,
A tank 3 is arranged above the base 1, and a pump device 4 provided in the tank 3 sucks up water from the tank 3 and sends it to the vaporization chamber 2. In addition, when the pump device 4 is locked with its button 6 pressed deeply,
The ball valve 6 was in pressure contact with the valve port to shut off the waterway.

Problems to be Solved by the Invention However, with such a structure, if there is water in the tank 4 when pouring water or finishing ironing, the button 6 should be pressed.
There was a problem with the water in the tank spilling out if you pushed it in deeply to lock it, that is, forgetting to switch it to dry mode.

The present invention solves these problems and prevents water from spilling from the tank even when the tank is removed from the iron body.

Means for Solving the Problem In order to solve this problem, the present invention has a structure in which a normally closed valve is provided in the tank and a pump device is provided on the iron body side.

Effect With this configuration, the passage for supplying tank water to the vaporization chamber and the pump device with the opening/closing device for controlling the water in the tank are located on the main body rather than on the tank, so when the tank is attached to the main body at the bottom of the tank. It is now possible to install a normally closed valve that sends water from the tank to the passage, making it possible to create a steam iron that does not spill water even if you forget to operate the opening/closing device and remove the tank from the main body. .

EXAMPLE The example will be explained below with reference to FIGS. 1 and 2. In the figure, 11 is an iron pace, and a vaporizing chamber 12 is integrally formed with the vaporizing chamber lid 1.
Covered by 3. A water conduit mounting plate 14 is fixed onto the pace 11 with screws 15. A headrace 18 is formed on the headrace mounting plate 14 by overlapping a headrace main body 16 and a headrace backing 17 made of heat-resistant rubber.

A seal lip 17& that faces the shape of the headrace 18 is formed on the sealing surface of the headrace backing 17 with the headrace main body 16. The water conduit seal backing 17 is positioned on the pace 11 side. Headrace main body 1
6 incorporates a valve device 19, which is linked to a thermally responsive member 20 incorporated in the pace 11 via a valve spring 21.
The water conduit 18 is opened and closed by vertical movement.

The upper surface opening of the headrace body 16 is covered with a lid backing 22, which is attached to the headrace body 16 with a mounting bracket 23 and constitutes a part of the headrace 18. An elastic connection backing 24 is attached around the inlet 18a of the water conduit 18, and its upper surface is in close contact with the peripheral plane 26b of the tank outlet 251L formed at the bottom of the tank 26 to connect the tank 26 and the water conduit 18. Let's communicate. The tank outlet 26& at the bottom of the tank is normally open by a normally closed valve 26, and when the tank 26 is set, it is pushed open by a push-up part 27 formed as a part of the connection backing 24, and the water in the tank 26 is released. is made to flow into the water conduit 18. A drip nozzle 28 is provided at the outlet 18b of the water conduit 18, and this drip nozzle 28 communicates the water conduit 18 and the vaporization chamber 12 through the opening 132L of the vaporization chamber lid 13. A ball valve 29 is disposed in a hollow portion 30 forming a part of the headrace 18 of the headrace main body 16, and a spring 32 is moved up and down by operating a button 31 to freely open the headrace 1.
8 can stop the flow of water.

A pump device 3a is provided integrally with the iron body 34 and is activated by operating the button 31.

Next, to explain the flow of water step by step, as shown in FIG. It flows along the water conduit 18. Furthermore, ball valve 2
9. It flows through the valve device 19 and into the vaporization chamber 12 from the drip nozzle 28 as shown by arrows E and F. Here tank 26
is installed in the main body, the water in the tank 26 is sent to the vaporization chamber 12 through the path as described above. When the button 31 is pressed down, the pump device 33. The spring 32 and the ball valve 29 are pushed away from the water conduit main body 16 to close the passage 18 and no water is supplied to the vaporization chamber 12.

The valve device 19 is opened and closed by a thermally responsive member 20, closes the passage 18 when the pace 11 is cold, and opens the passage 18 when the temperature reaches a predetermined temperature, and operates regardless of the operation of the button 31. Further, when the button 31 is moved up and down, a large amount of water is sent to the vaporization chamber 12 by the pump device 33, and the amount of steam can be increased. Further, when the tank 26 is removed from the main body 34, the normally closed valve 26 closes the opening 261L of the tank 26, and no water spills from the tank.

Effects of the Invention As is clear from the description of the above embodiments, the present invention has a pump device that also serves as an opening/closing device for the water passage attached to the iron body, and the tank has no opening/closing device.
Since it is equipped with a normally closed valve, there is no chance of water spilling from the tank due to forgetting to press the button on the tank, and if the tank is equipped with a pump device, there is no need to discard parts due to poor welding during tank manufacturing. By having a pump device, it can produce a large amount of steam that is effective for smoothing out wrinkles, making it an easy-to-use and efficient iron.
