Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a steam iron in which water from a water tank is evaporated by a heater and steam is ejected from the bottom of the iron body.

(B) Conventional technology In the past, as in, for example, Japanese Utility Model Application Publication No. 55-238, a water receiving plate that turns over when the temperature reaches a temperature suitable for generating steam is disposed directly inside the steam generation chamber and is attached to a tank. Since the water in the tank is directly opposed to the opening that allows water to drip, the water in the tank will drip onto this water receiving plate, resulting in the water receiving plate rusting or water dripping onto the hot water receiving plate. Therefore, there was a drawback that the temperature difference became large and the product deteriorated.

fl Problems to be Solved by the Invention The present invention solves the above-mentioned drawbacks and aims to prevent rust or deterioration of the thermally responsive member that operates the second opening/closing rod that opens and closes the nozzle opening.

B) Means for Solving the Problems The present invention forms a compartment in the base separated from the vaporizing chamber, and a thermally responsive member that operates by detecting the temperature of the base is provided in this compartment, and the thermally responsive member operates by detecting the temperature of the base. A second opening/closing rod is provided on the upper surface of the member to open and close the nozzle opening from the bottom surface in conjunction with the operation of the thermally responsive member, and the second opening/closing rod opens and closes the nozzle until the thermally responsive member reaches a predetermined temperature. The opening is closed.

(e) Since the operational heat-responsive member is placed in a compartment separated from the vaporization chamber,
Embodiment This embodiment will be described based on the drawings, which can prevent rust or deterioration of this thermally responsive member. (1) is the heater (
2), a vaporization chamber (3) close to the heater (2), steam holes (4) communicating the vaporization chamber with outside air, and the vaporization chamber (3).
and a compartment (5) divided into four cylindrical partition walls.

(6) is a base lid that covers the vaporization chamber (3) and the compartment (5), and has an opening (7) at a suitable location that communicates with the vaporization chamber (3). (8) is an iron cover provided above the base (1), (9) is a handle provided on the top surface of the iron cover, and (lO) is the iron cover (8).
It is a tank that is detachably installed between the handle and the handle (9) and stores water, and has a nozzle (11) formed on its bottom surface. (12) Cylindrical part (13
), and opens and closes the opening (14) of the nozzle (11) at its lower end, and is always urged upward to open the opening of the nozzle (01). When you manually operate the operating member that does not operate, it descends and the nozzle (11
) for closing the opening (141). (19 is a cylindrical flexible heat-resistant resin backing made of silicone rubber, for example, provided between the iron cover (8) and the base lid (6), A small diameter hole (16) is formed by bending the upper edge inward, and a contact surface (171) that contacts the lower surface of the nostle circle is formed on the upper surface, and this contact surface (171) is formed on the upper surface of the base cover (8). The backing (15) has its lower end extending horizontally so that it extends along the opening (7) of the base lid (6) together with the upper surface of the base lid (6).
) forms a water passage head that communicates with A first spring is installed in the backing (2) and always urges the contact surface α'7) upward; A thermally responsive member (21) such as a reversible bimetal that senses and reverses its operation is a second opening/closing rod whose lower end is connected to the upper surface of the approximately central portion of the thermally responsive member. ) is vertically slidable through a guide hole (2) provided in the backing (19), and the lower end of the hole α0 of the backing (19) can be opened and closed using its upper end.

The cause is a second spring interposed between the base lid (6) and the thermally responsive member (2), which assists the reversal operation of the thermally responsive member (2).

Next, the operation will be explained based on the marks to eIζ in FIG. First, when ironing using steam,
Attach the tank (1■ holds water and this tank 10). At this time, the backing a9 comes into contact lI[iα′7
1 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 operating member (not shown), the first opening/closing rod α2 is moved upward. Then, open the 0-angle opening of the nozzle (11J).If 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 (i) As shown in the figure, it is in an upwardly inverted curved state, and the second opening/closing rod (21J
is blocking the opening of the hole α in the backing 0ω. Therefore, water does not flow into the water passage (3) and the nozzle (11J opening (
Even if 141 is opened, no gas is supplied into the vaporization chamber (3). Then, when the base (1) is heated by the heater (2) and the water is vaporized and steam generation reaches the appropriate temperature, the thermally responsive member The second opening/closing rod α2 opens the hole (10) on the backing side. In this state, the water in the tank (10) passes through the nozzle αD, the backing a9, and then into the water passage a8). After being preheated from the base lid (6), it flows into the vaporization chamber (3), is efficiently vaporized, and is ejected from the steam holes (4). The operation member (not shown) is operated to move the first opening/closing rod (12) downward, and the opening (14) of the nozzle aυ is opened.
It is possible to stop the supply of water to the vaporization chamber (3) by blocking J, and switching between steam and dry can be performed arbitrarily by manual operation.

Also, when the tank α0) is removed to discard the water in the tank αω after ironing is completed, the water remaining in the water passage aQ flows into the vaporization chamber (3) and is vaporized by the residual heat of the base (1). At the same time, as shown in (/1), the contact surface opening η of the packing opening 5 is released by the pressure of the nozzle (11) and moves upward to its original state, so even if the second opening/closing rod (21) is Even in the moving state, the backing (hole 06 of 19) is opened, and the water remaining in this hole Q6) flows into the vaporization chamber (3) through the water passage (marked 1) and Same as base (1
) is vaporized by the residual heat.

In addition, since the compartment (5) is completely separated from the vaporization chamber (3) formed in the base (11) by the partition wall, water droplets from the tank (101) can pass through the vaporization chamber (3). It does not enter into the compartment (5), and therefore the thermally responsive member (3) located therein is prevented from rusting or deteriorating due to water.

In addition, since the hole (16) is formed of a flexible heat-resistant resin backing (151), even if there is variation in the position of the second opening/closing rod's upward movement, the second opening/closing rod's 0
! Even if the abutting surface of the backing (2υ) is deformed, the second opening/closing rod (2υ) will surely fit into the hole (16
(g) Effects of the Invention Since the present invention is configured as described above, it is possible to prevent rust or deterioration due to water droplets on the thermally responsive member that operates the opening/closing rod that opens and closes the hole. It is possible.
