Abstract

PURPOSE:To eliminate careless water supply to a vaporizing room even when a communicating path to the vaporizing room is forgotten to be closed at the time when an iron is vertically self-standed under a used state or after the iron is used by providing a valve body opened when the iron is vertically self-standed communicating the front part of a rear tank room and the vaporizing room with the communicating path, and opening and closing this communicating path with an opening and closing valve. CONSTITUTION:A water passing hole 25 is blocked through a spring 26 by a valve body 27 all the time. This valve body 27 has a T-shape, passes through a rear tank room 23, and abuts its rear part on a freely expansible seal packing 28. A bar-shaped operation rod 30, one edge of which penetrates the internal part of a handle body 8 and protrudes to an external part, and the other of which abuts through the seal packing 28 on the valve body 27, protrudes the other edge to the external part when the water passing hole 25 is closed by the valve body 27, and the operation rod 30 is pressed, moves the valve body 27 into a front tank room 22 against the force of the spring 26, and opens the water passing hole 25 when an iron main body 1 is vertically self-standed on a table surface, etc. The careless generation of the steam when the iron main body is self-standed can be eliminated, and the safety can be improved by forming a water tank 7 with the front tank room 22 and the rear tank room 23 in the above-mentioned manner.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a steam iron.

(b) The conventional technology for partitioning the inside of a tank is based on Utility Model Publication No. 62-38656.
However, because the nozzle part is located in the rear water storage chamber, the nozzle part is submerged in water even when the freestanding body is not in use, and water drips into the vaporization chamber, causing constant steam generation. There were drawbacks.

(c) Problems to be Solved by the Invention The present invention prevents inadvertent water from entering the vaporization chamber, even if the iron is standing vertically during use or if the communication path to the vaporization chamber is forgotten to close after use. The purpose is to provide a steam iron that can eliminate supplies.

B) Means for Solving the Problems The present invention divides the interior of a water tank into a front tank chamber having a water supply port and a rear tank chamber that covers the rear and bottom portions of the front tank chamber using partition walls. A water hole is drilled in the rear part of the partition wall to allow water from the front tank chamber to flow to the rear tank chamber, and a valve body is provided to close the water hole when the iron body is in use and open it when the iron body is standing vertically. The front part of the rear tank chamber and the vaporization chamber are connected through a communication passage, and the communication passage is opened and closed by an on-off valve. This is a characteristic feature.

(E) Function With this configuration, only a predetermined amount of water is supplied to the rear tank chamber that communicates with the vaporizing chamber, so when the iron body stands up vertically while using steam, water is supplied from the rear tank chamber. Even if the water supply to the vaporization chamber is left in a state where steam is generated afterwards, there is little residual water in the rear tank chamber, so the remaining water in the vaporization chamber can be eliminated by residual heat.

(f) Example +11 is a steam iron main body, in which the heater (2) is completely buried, and the pace (4) has a vaporizing chamber (31) installed inside.
A cover (6) is installed on the top surface of this pace (4), which is fixed with screws (51), and a water tank (7) and a handle body (81, etc.) provided above this cover f61.

The vaporization chamber (3) was purchased so that it could communicate with the water tank (7) via a communication gasket 0a provided on the vaporization lid (9), and a screw (1?J) was installed on the bottom surface of the pace (4). A pace i[141 that is detachable and has a steam hole U31 is provided.

Also, adjacent to the vaporization chamber (3) is a reversible bimetal plate 0.
5). When this bimetal plate (151) detects the temperature at which steam is generated in the vaporization chamber (3), it reversely curves upward. rod u
Gl is provided.

The water tank (7) has a partition wall with a water supply hole CIIJf, and defines a front tank chamber 1231 that covers at least the rear and bottom portions of the front tank chamber (22). The upper part of the chamber and the upper part of the rear tank chamber communicate with each other, and the rear wall (20
A water passage hole (251 (2511) is bored in a).The water passage hole 125+ is always closed by a valve body - with a spring 1261 interposed.

It is brought into contact with 1. 3G is a rod-shaped operating rod that penetrates the inside of the handle body (8) at one end and protrudes to the outside, and the other end contacts the valve body 9 through the seal gasket (3G). When the hole 1251 is closed, the other end is made to protrude outside, and when the iron body is vertically supported on a table or the like as shown in Figure 1, the cocoon operation lever is pressed and the valve is closed. The body Cmk is moved into the front tank chamber (23) against the force of the spring and opened to the water passage hole 5. In the front part of the rear tank chamber f231, there is a hole ζot communicating with the communication gasket 0α. This hole (2) and the four gaskets (101) form a communication path (t) that communicates with the vaporization chamber (31) and the front part of the rear tank chamber +231.

The forward tank 'AI,! An on-off valve ω for opening and closing the communication path (to) is conveniently provided at the front of the bottom surface of 4. This on-off valve (9) is telescopic so that it can move up and down, and is normally closed to the communication path C151. This on-off valve (
9) is the guide part +31N installed inside the front tank room.
It is supported by a press rod that is slidably mounted on the shaft.

For this pressure breakthrough, a curved rod is attached that is freely bendable and has one end supported and fixed on a protrusion (G) of a partition wall that partitions the bottom of the front tank chamber. And this curved rod (turn)
The partition wall opening 1 and the tank chamber 1231L are located approximately at the center of the lower surface of the tank.
A presser (c) penetrating the bottom of D is provided so as to be able to freely move up and down. The lower end of this presser is in contact with the upper part of the moving rod (+61).

(The steam rod is placed above the pressure rod 091 so that it can move up and down freely with a spring @ρ interposed, and a steam button ■ is provided at the top.When this steam & IJ uJt is set in the upper position, When steam is generated, steam rod 1 (4) and pressure rod 1 are
A gap is created between the pressure rod 3Eli and the pressure rod 9: when it rises by this gap and comes into contact with the steam rod, the opening/closing valve (9) also rises and opens the communication path (to), leading to the vaporization chamber 131. water can be supplied.

10,000, when the steam button ■ is pressed and set to the lower position, it is a dry time when no steam is generated, and the steam release does not always press the pressure rod t31', and the vaporization chamber (3)
There is no water supply to the area.

To explain the operation of such planting, first, as shown in Figure 1,
The iron body +11 is made to stand up almost vertically and the water supply port 1211
When water is supplied to the front tank chamber from the front tank chamber, since the operating lever is pressed, the valve body cn opens and water is also supplied to the rear tank chamber. At this time, the steam button and steam lever are raised to generate steam.

Next, as shown in Fig. 2, the heater (2) is turned on and the heater (2) is energized, and when the temperature near the vaporization chamber (3) reaches a temperature suitable for generating steam, the bimetal plate 151 is turned upward and curved. , push up the movable rod (IGI and pressing rod) and lift the curved rod as shown in Figure 6, as a result, the pressing rod (39
Raise the on-off valve (2) and fully open the communication path (to).
Water from the rear tank chamber 231 is guided dropwise to the vaporization chamber (31) to generate steam.

Therefore, since the communication path (to) is located in the front part of the iron body Il+, even if the communication path (to) is opened and the iron body (11 is made independent) in the steam generation state as shown in FIG. 4, the vaporization chamber ( Since the water in the rear tank chamber 1231 is not supplied into the tank 31, no steam is inadvertently spouted out horizontally.

Also, as shown in Fig. 5, with the iron main body in a horizontal position and in a state where steam is generated, the communication passage 85 is opened to allow communication to the heater (2)! Even if the rear tank chamber (3) is shut off and left alone, almost no water will remain in the rear tank chamber (3) due to its small volume.
3) and can prevent deterioration of the steam hole U31.

Also, as is clear from Figure 3, the rear tank room [231
The water level inside is the front tank Wc! *The water level can be obtained higher than the vaporization chamber! 31 can be lowered by 711i to water 7 with appropriate water pressure.

(G) More than the effects of the invention, by forming a water tank with a water tank in the front and the rear, it is safe to avoid inadvertent generation of steam when the iron body stands on its own, and it is safe to use after use.
This eliminates shallow water entering the vaporization chamber, prevents deterioration, and allows for an appropriate supply of water droplets into the vaporization chamber.
