Description

[Detailed description of the invention] The present invention relates to a drip-type steam iron.

In conventional drip-type steam irons, if you forget to close the drip valve after using the iron and store the iron, the remaining water in the tank will leak out from the drip pulp and this will affect the number of times you iron the iron. There is a risk that the product will corrode if it gets wet, and there are also problems such as getting the box in which it is stored wet. In addition, when drying eyelids at low temperatures, if the opening/closing button is left in the open position, the dripping water will not turn into steam, but will leak out and wet the fabric.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to eliminate the above-mentioned drawbacks of the conventional method by automatically opening and closing the dripping pulp through the deformation action of a bimetal that is sensitive to the temperature of the iron's pace. The purpose is to provide a drip-type steam iron.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

In FIG. 1, 1 is a handle, 2 is a body cover, 3 is a pace, 4 is a tank, 5 is a tank water inlet, 6 is an iron temperature setting dial, 7 is a cord, and 18 is a valve opening temperature dial. A valve seat for dropping pulp 8 is provided in a dripping port formed in the tank 4, and this dripping port opens into a steam generation chamber IO formed on the upper surface of the pace 3. A steam passage 11 is bored between the steam generation chamber 20 and the bottom surface of the pace 3. Dripping pulp 8
A 21 dollar portion formed at the lower end of the valve rod 9 approaches and separates from the valve seat to open and close the drip opening. And the top end of the red 9 with the tank 4. Next, we will explain about the bimetal 12 that opens and closes the dripping valve 8 fully automatically.The bimetal Z2 forms a band-shaped plate when moved around, and one end of the bimetal Z2 is integrally protruded from the upper surface of the pace 3 and connects the hole 4& formed in the tank 4. It is fixed to the inserted receiving portion 3a, and the other end is attached to the valve rod 9 on the outside of the tank 4 via an engaging means 13 shown in FIG. The engagement means I3 includes a pair of flanges 14.14 fixed to the valve rod 9 with a gap therebetween, and a two-pronged fork member 16 inserted between the pair of flanges to loosely insert the valve rod 9 into the groove 15. It consists of The fork member 16 is fixed to the other end (free end) of the bimetal 12 and transmits the vertical movement of the other end due to thermal deformation of the bimetal 12 to the valve rod 9 via the flange 14.14. While opening and closing the dripping valve 8, the valve rod 9 is moved horizontally toward the other end of the bimetal.
The groove 15 slides to release the water without affecting the water. The above-mentioned engaging means I3 is not limited to that of this embodiment, but may be one in which an interlocking element provided on the bimetal side is slidably inserted into a fine hole provided on the valve rod 9 side. There is no problem as long as it has a mechanism that satisfies the above functions. If the bimetal 12 has a short arm and the valve body has a small lifting height,
This engaging means 13 may be omitted and the Pymetal k12 may be directly fixed to the valve rod 9.

A valve opening temperature setting means 17 is provided in a portion of the valve rod 9 that passes through the front end of the handle 1. As shown in FIG. 3, the valve-opening temperature setting means 17 rotates the valve-opening temperature dial z8 to change the compressive force of the spring 19, transmits the stretching force to the dropping pulp 8 via the valve rod 9, and causes the bimetal 12 to The opening and closing of the dropping pulp 8 can be delayed or accelerated. For example, the valve opening hot water temperature diagram fiv1B is partially inserted in a notch-shaped groove 1' provided at the front end of the handle I, and
The valve rod 9 passes through the center of the threaded body 20 integrally connected to this, and this threaded body 20 is connected to the valve rod 9.
It can be rotated around the center. and screw body 20
An adjustment plate 22 that is prevented from rotating by a guide 21 but can be moved up and down is screwed together, and a coil spring 19 is interposed between the adjustment plate 22 and a lunge 23 installed in the pulp pad 9. equipped. However, the spring Z9 uses its spring force to keep the dripping valve 8 in a normally closed state. The upper end of the valve rod 9 passing through the front end of the handle 1 is exposed on the handle I and moves up and down slightly as the dripping pulp 8 is opened and closed. Therefore, the valve rod exposed portion 9' can be used as a valve opening/closing display means and a manual valve closing means.

Since this embodiment is constructed as described above, when it is used, first fill the tank 4 with water, set the iron temperature setting dial 6 and the valve opening temperature dial 18 to the required scales, and turn on the switch. Then, the pace 3 and the attachment part 3a are heated, and the bimetal 12 is heated through the attachment part 3a due to the temperature rise. The bending deformation of the bimetal 12 due to the rise in temperature of the bimetal 12 acts to lift the valve rod 9 in the valve opening direction (upward) via the engagement means 13'ft, but due to the bias of the suge ring 19, the bimetal 12 moves to the valve opening temperature dial Z8. The valve opening set temperature, that is,
The dripping pulp 8 does not open until the steam generation chamber ZO reaches a temperature sufficient to instantaneously vaporize the dripping water. When the bimetal temperature reaches the set temperature, the deforming force of the bimetal I2 resists the sgelling 19 and automatically opens the dropping pulp 8. When the dripping pulp 8 is opened in this manner, the water in the tank 4 is dripped into the steam generation chamber 10 through the valve, and is turned into steam by the steam generation chamber 10, which is heated to a sufficiently high temperature. Then, the steam is ejected from the steam passage 11 due to its own steam pressure, making it possible to install the eye with the steam. On the other hand, the pace 3 continues to be heated until it reaches the temperature set by the iron temperature setting dial 6, and when the set temperature is reached, the current supply is cut off by a thermomechanism (not shown). During this time, the displacement of the free end of the bimetal 1-2 caused by thermal deformation is absorbed by the engagement means 13. Furthermore, while steam is being generated, by pressing the valve rod exposed portion 9' provided at the front end of the handle I, the dripping valve 8 can be manually closed as necessary to stop the steam from blowing out, allowing dry ironing. . Also, when you have finished ironing and want to store the iron, you can simply turn off the iron. That is, when the iron is cooled and the temperature drops below the valve opening set temperature, the deformation of the bimetal 12 is restored, and the dripping valve 8 is automatically closed by the deformation force and the biasing force of the sgel ring Z9.

This eliminates the need to close the drip valve, which was required in the past, when ironing with residual heat from the iron or when storing the iron. Therefore, there is no leakage of water from the dripping valve, and there is no risk of problems such as wetting the cloth or the storage area or inviting corrosion of the iron itself.

Note that the spring 19 is not necessarily required in the present invention.

As mentioned above, the present invention is a drip-type steam iron that has a built-in bimetal and automatically opens and closes the drip valve by deformation of this bimetal, so the structure is extremely simple, and steam is automatically spouted when the temperature is higher than the set temperature. It can automatically prevent steam blowout and water leakage when the temperature is below the set temperature. Therefore, it is possible to provide a steam iron that is easy and reliable to handle, and that does not invite corrosion of the sheer iron itself that wets cloth or the iron storage area due to unnecessary water leakage.
