Description

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

(b) Conventional technology Conventionally, in a steam iron with a removable tank, there is a base with a vaporizing chamber formed therein, a tank placed on the base, and a tank provided at the bottom of the tank that communicates the tank with the vaporizing chamber. A first on-off valve that opens and closes the water passage and the opening leading from the tank to the water passage using a bimetal actuated by the heat of the base, and the opening leading from the water passage to the vaporization chamber that opens and closes using a manual operating device. A device equipped with a second on-off valve and supplying water to the vaporization chamber after the base reaches a predetermined temperature in order to stabilize the ejection of steam is disclosed in, for example, Japanese Utility Model Application No. 56-82994. However, with this steam iron, if the above-mentioned valves are closed when the water in the tank is discarded, water remains in the water passage, so water stains and impurities contained in the water remain in the water passage. accumulates,
The drawback was that water was not supplied from the tank to the vaporization chamber.

(c) Problems to be solved by the invention In consideration of the above-mentioned drawbacks, the present invention aims to prevent water from remaining in the water passage when the iron is not in use.

(d) Means for solving the problems The present invention is a steam iron, and the first feature is a nozzle opening provided at the bottom of the tank that can be opened and closed.
The opening/closing rod, the water passage that guides the water in the tank, the cylindrical packing that connects the nozzle opening and the water passage in a watertight manner, the thermally responsive member provided on the base, and the vertical movement due to the operation of the thermally responsive member. The device is characterized in that it has a second opening/closing rod that allows the upper opening of the packing to be opened and closed.

(e) Function Since the present invention is constructed as described above, when the second opening/closing rod moves upward and closes the upper opening of the packing as the temperature of the base decreases, water flows from the tank to the water passage. The water that remains in the water passage is led to the vaporization chamber and vaporized by the residual heat of the base.

(f) Example This example will be explained based on the drawings. Reference numeral 1 denotes a base made of aluminum in which a heater 2 is embedded, which includes a vaporization chamber 3 close to the heater 2, steam holes 4, 4 that communicate the vaporization chamber with outside air, and the vaporization chamber 3.
and a divided compartment 5 are formed. Reference numeral 6 denotes a base lid that covers the vaporization chamber 3 and the compartment 5, and has an opening 7 communicating with the vaporization chamber 3 formed at a proper location. 8 is an iron cover provided above the base 1; 9
1 is a handle provided on the top surface of the iron cover;
0 is a tank that is detachably provided between the iron cover 8 and the handle 9 and stores water, and has a nozzle 11 formed on its bottom surface. Reference numeral 12 denotes a first opening/closing rod that moves up and down in a cylindrical portion 13 formed in the tank 10 and opens and closes the opening 14 of the nozzle 11 at its lower end, and is always urged upward to open the opening 14 of the nozzle 11. However, when an operating member (not shown) is manually operated, it descends and closes the opening 14 of the nozzle 11. 15 is a cylindrical packing made of silicone rubber, for example, provided between the iron cover 8 and the base lid 6, and the upper edge thereof is bent inward to form a small diameter opening (upper opening) 16.
and a contact surface 17 that contacts the lower surface of the nozzle 11, and this contact surface 17 is connected to the base cover 8.
It protrudes from the top surface. The packing 15 has one lower end extending horizontally to form a water passage 18 communicating with the upper surface of the base lid 6 and the opening 7 of the base lid 6. Reference numeral 19 is a first spring that is installed in the packing 15 and always urges the contact surface 17 upward; 20 is a reversible bimetal that is arranged in the compartment 5 and operates in reverse by sensing the temperature of the base 1; 21 is a second opening/closing rod whose lower end is connected to the approximate center of the thermally responsive member, and when the thermally responsive member 20 operates, it slides up and down through the guide hole 22 provided in the base lid 6. The lower end of the opening 16 of the packing 15 can be opened and closed using its upper end. A second spring 23 is interposed between the base lid 6 and the thermally responsive member 20, and assists the reversing operation of the thermally responsive member 20.

Next, the operation will be explained based on A to C of FIG. First, when ironing is performed using steam, water is stored in the tank 10 and the tank 10 is attached. At this time, the packing 15
The contact surface 17 is pressed against the lower surface of the nozzle 11 and moves slightly downward against the biasing force of the first spring 19. Then, by operating an operation member (not shown), the first
The opening/closing rod 12 is moved upward to open the opening 14 of the nozzle 11. When the temperature of the base 1 is lower than the appropriate temperature for steam generation, such as when the heater 2 is initially energized, the thermally responsive member 20 is in the state shown in FIG. It's blocked. Therefore, even if water does not flow into the water passage 3 and the opening 14 of the nozzle 11 is opened, the vaporization chamber 3
It is not supplied inside. Then, when the base 1 is heated by the heater 2 and reaches the appropriate temperature for vaporizing water, the thermally responsive member 20 is instantly reversed with the help of the second spring 23, as shown in FIG. The opening/closing rod 12 of No. 2 opens the opening 16 of the packing 15. In this state, tank 1
The water in 0 passes through the nozzle 11 and packing 15,
After being preheated by the base lid 6 in the water passage 18, it flows into the vaporization chamber 3, where it is efficiently vaporized and ejected from the steam holes 4, 4. Of course, even during use, the first opening/closing rod 12 can be moved downward by operating an operating member (not shown) to open the opening 14 of the nozzle 11.
It is possible to stop the supply of water to the vaporization chamber 3 by blocking the vaporization chamber 3, and switching between steam and dry mode can be performed arbitrarily by manual operation.

Also, when the tank 10 is removed to drain the water after ironing, the water passage 1
The water remaining in the gas chamber 8 flows into the vaporization chamber 3 and is vaporized by the residual heat of the base 1, and as shown in C, the contact surface 17 of the packing 15 is released by the pressure of the nozzle 11 and moves upward to its original state. Therefore, even if the second opening/closing rod 21 is moving upward, the opening 16 of the packing 15 is opened, and the water remaining in the opening 16 flows through the water passage 18 to the vaporization chamber. 3 and is vaporized by the residual heat of the base 1 as described above.

(g) Effects of the invention Since the invention is constructed as described above,
Since the steam jet can be stabilized and water does not remain in the water passage when the iron is not in use, a highly reliable iron that operates reliably over a long period of time can be obtained.
