Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention Field of Industrial Application The present invention particularly relates to a steam iron used for commercial purposes.

Conventional technology In particular, commercial steam irons are frequently used, so the valve device that controls the water supply to the vaporization chamber is removable and can be disassembled and cleaned to prevent blockages caused by water scale and dirt. It is common that the

Conventionally, this type of steam iron has been constructed as shown in FIGS. 3 and 4. Reference numeral 1 designates a vaporizing chamber disposed on the pace 2 and having a heater 3, and 4 a valve device detachably attached to the vaporizing chamber 1.

This valve device 4 includes a valve box 6 having an outflow hole 6 at the bottom, a valve crown 8 that is fastened to the valve box 6 to form a valve chamber 7, and a valve box 6.
The outflow hole 5 is welded to the side surface of the valve chamber 7 in conjunction with a metal water conduit pipe 1o that serves as an inflow passage 9 to the valve chamber 7 and an operating lever 11.
It consists of a plunger 12 that opens and closes. Generally, the water conduit 1o integrated into the valve box 6 was bent and extended to the rear side of the main body 13 and connected to a tank (not shown) via a rubber hose 14.

Problems to be Solved by the Invention However, with such a structure, the valve device 4 is placed above the high-temperature vaporization chamber 1, so it is heated considerably, and the outflow hole 6. Water scale inside the valve chamber 7 and in the inlet passage 9' near the joint between the valve box 6 and the water conduit 9.

And dust is likely to occur due to dust. If the valve device is removed and disassembled for cleaning, there will be no problem since the inside of the outflow hole 6 and the valve chamber 7 will be in a direction that is easier to clean than the outside, but in the inflow passage 9', it will be located where it entered. Therefore, cleaning was difficult and time-consuming.

Therefore, the present invention is designed to allow easy cleaning by removing the valve device and disassembling it even if blistering occurs due to adhesion of water scale and dirt.

The means to solve the problems and the technical means to solve the above problems are to make the valve box, valve seal, and plunger that opens and closes the outlet, which make up the valve device, disassemble and attach them removably. At the same time, a waterway is formed in the plunger to supply water to the vaporization chamber.

In other words, when a water channel is formed in the generally rod-shaped plunger, the shape of the water channel is necessarily linear, so even if water scale or dirt adheres to this water channel, This makes it easier to insert the straight cleaning pin that is normally used, making cleaning easier.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. 1 and 2, 21 is a base having a heater 22, 23 is a vaporization chamber formed on the pace 21, and 24 is a base having a heater 22;
25 is a water tank provided outside, and 25 is a water supply pipe that supplies water to the vaporization chamber 23 via a valve device 26, which is made of a combustible material such as silicone rubber. The valve device 26 is fastened to a valve box 28 which has an outflow hole 27 formed on the bottom surface thereof, which protrudes so as to face the vaporization chamber 23, and a threaded portion 28& formed on the upper part of the inner surface of this valve box 28, thereby forming a valve chamber 29. a valve seal 30,
It is composed of a plunger 31 having a substantially rod-shaped tip that opens and closes the outflow hole 27. The plunger 31 slidably passes through the valve seal 30, and has an opening/closing body 32 made of a heat-resistant elastic material such as fluororubber at its lower end, while a water supply pipe 25 is stopped at its upper end! 633. The plunger 31 is hollow and has a water channel 34 that communicates the water supply pipe 26 and the valve chamber 29.
is formed. 36 is an opening/closing spring that urges the plunger 31 toward the outflow hole 27 via the opening/closing body 32; 36 is an O-ring that seals the valve box 28 and the valve seal 3o; and 37 is a seal that seals the plunger 31 and the valve seal 30. O-ring 38 is a washer placed between O-ring 37 and opening/closing spring 36. 39 is an operating lever for opening and closing the valve device 26;
It is rotatably attached to a support fitting 41 fixed to the upper part with a screw 40, and has a lever knob 43 placed at one end just beside the front part of the handle 42, and the other end has a lever knob 43 located at the upper part of the plunger 31. The hole 4 of the engaging body 46 is attached to the stepped portion 311L formed in the hole 4 with a screw 44 so as not to come off.
51L, and when the operating lever 39 rotates, the plunger 31 moves up and down.

46 is a recess 232 in which the valve device 26 is formed on the vaporization chamber 23
It is a holding plate that is a steel plate that can be attached to the L removably.
It is attached with screws 47.

48 is a backing made of fluororubber or the like that seals the valve box 28 and the vaporization chamber 23.

49 is a steam chamber communicating with the vaporization chamber 23, 6o is a steam outlet, and 61 is a base cover.

Next, the operation of the configuration of this embodiment will be explained.

First, the case of normal use will be explained.

The water in the water tank 24 is connected to the water supply pipe 26 and the plunger 3.
The liquid flows sequentially through the water channel 34 of No. 1 and reaches the valve chamber 29. At this time, when the lever knob 43 is pushed down, the plunger 31 rises, the previously closed outflow hole 27 opens, water is supplied into the vaporization chamber 22, and the water is instantly vaporized and steam flows into the steam chamber 49. The steam is ejected from the steam ejection hole 60.

Furthermore, when the lever knob 43 that had been pressed down is released, the plunger 31 is pushed down by the repulsive force of the opening/closing spring 350, closing the outflow hole 27 and stopping the supply of water to the vaporization chamber 22.

Next, a case where the inside of the valve device 26 is cleaned will be explained.

To remove the valve device 26 from the iron body, remove the stopper 33.
Remove the water supply pipe 26 from the plunger 31, loosen the screws 40 and 44, and remove the engaging body 45 and the support fitting 4.
1, remove the setscrews 47 of the presser plate 46 to remove the iron components, such as the handle 42 and the cover 61.
This can be done without removing it. By loosening the valve seal 30 of the removed valve device 26, the valve box 28, valve seal 30° plunger 31 are separated. Even if water scale or dirt adheres to the inside of the outflow hole 27, the valve chamber 29, and the water channel 34, it can be easily scraped off to the outside with a relatively easily available straight bottle 62.

In addition, the function of the plunger 31 is not only to open and close the outflow hole 2T, but also to serve as an inflow path for water to the valve device 26, so that the valve device 26 can be configured compactly and can be installed by removing it. Another advantage is that it can be done quickly.

Effects of the Invention As described above, the present invention allows the valve device to be detachably attached to the main body, the valve box, valve seal, and plunger that constitute the valve device to be disassembled, and to supply water to the vaporization chamber to the plunger. With a water channel formed, it is possible to easily clean water scale and dirt that has adhered to the inside of the valve device, and it also has the following effects.

In other words, the plunger has the function of opening and closing the outflow hole, and the function of acting as an inflow passage for water into the valve device is added at the same time, allowing the valve device to be configured compactly and making it easy to install and remove the valve device. It can be done.
