Abstract

PURPOSE:To aim at the miniaturization of a body and improvement in its working property by installing a steam-dry selector means, maintaining both opening and closing states in a water passage, in a cap attached to a water inlet free of detachment. CONSTITUTION:A cap 33 is attached to a water inlet 8 free of detachment with a support member 15 screwed. A steam-dry selector means 48 consists of an operating button 39, a rotator 40, a second spring 43, a presser 42 and a support plate 44. In the case of drying, if the operating button is pushed, a claw 41 of the rotator 40 hits on a short first stopping groove 37 and engaged therewith, while the rotator 40 and the operating button 39 are held upward by the second spring 43. In this case, since depressing force of the presser 42 comes weak, an actuating lever 14 is pushed up by a first spring 32, and thereby a valve 31 hits on a valve seat 30, preventing water from flowing into an evaporating chamber 4. In the case of steaming, if the operating button 39 is depressed again, it depresses the actuating lever 14, separating the valve 31 from the valve seat 30, and water in a tank 7 gets into the evaporating chamber 4 from a nozzle hole 11 and evaporated into steam, thus it is sprayed out of a steam hole.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a steam iron in which a water inlet provided in a tank is directly blocked by camping.

(b) Conventional technology The tank of a general steam iron, for example,
- As shown in Publication No. 12799, a water supply and drainage port is provided at the top of the tank, and when supplying and draining water, the push button provided at the top of the nozzle is operated to open the water supply and drainage port and connect it to the water supply and drainage port. Water is supplied and drained from the water supply and drainage fittings. However, this type of structure for blocking the water supply and drainage ports is effective when the iron body is large and the overall height is set large in advance, but if the overall height is small (not matching the set), it is effective. The reason for this is that if the iron body is small, there is not enough space above the water supply and drainage port (water inlet) of the tank, and there is a valve inside the tank that opens and closes the water supply and drainage port. Examples include not being able to pay for purchases.

(C) Problems to be Solved by the Invention The present invention provides a steam/dry switching means on the can knob that closes the water inlet of the tank, and makes use of the space inside the cap by assembling the can alone. to reduce the space occupied by the above-mentioned turning means, and to
To simplify the assembly, disassembly, and cleaning of a dry switching means.

(d) Means for Solving the Problems The present invention provides a base having a heater and a steam hole and forming a vaporizing chamber communicating with the steam hole, and a water inlet provided above the base communicating with the vaporizing chamber. A tank having a water inlet communicating with the water inlet, a water passage provided between the vaporization chamber and the water inlet, and a cap removably attached to the water inlet, the cap indicating an open state and a closed state of the water passage. The structure is provided with a steam/dry switching means for holding.

(E) Function The present invention is equipped with a steam/dry switching means for opening and closing the water passage provided between the tank and the vaporization chamber on the cap that is detachably attached to the water inlet of the tank, so that the inside of the cap can be switched between steam and dry. It can be used as a storage space for tools, the iron body can be made smaller, and the cap can be assembled by itself, greatly improving work efficiency. Also,
A closure means for blocking the base prevents water from flowing out from the steam hole when the cap is removed.

A temperature control knob changes the set temperature of the thermostat (49) via the shaft (57). (58)
is a back cover provided at the rear of the base (1), and (59) is a power cord led out from the iron cover (50).Next, the operation will be described. First, when pouring water into the tank (7), loosen the cap (33), remove it, and pour water into the support member (15).The water enters the cavity (34) and flows through the water guide (17) into the tank. (7) Water is poured into the tank.

Thereafter, the cap (33) is screwed onto the engaging portion (19).

When using it in a dry state, press the operation button (39) as shown in Figure 2 (a), and the claws (41) (
41) hits the short first stop grooves (37) and is locked, and the rotor (4) is stopped by the second spring (43).
0) and the control button (39) are held upward. In this case, the claws (41) (41) of the rotor (40) and the first stop groove (
37037) is the same as that disclosed in Japanese Utility Model Publication No. 52-57275. As the operating button (39) rises as described above, the pressing force of the pusher (42) becomes weaker, so the operating rod (14) is pushed up by the first spring (32) and the valve (31) moves toward the valve seat (30). ) to prevent water from flowing into the vaporization chamber (4).

When using it in a steam state, when the operation button (39) is pushed down again, the rotor (4o) is pushed down as shown in Fig. 2 (b), and the claws (41) (41) are moved into the long second stop groove (38).
) (38) and was locked (Jetko Sho 52-57)
(See Japanese Patent No. 275) The second spring (43) is compressed and pushes down the pusher (42). - Due to this pushing down, the lower end of the pusher (42) presses the upper end of the operating rod (14), impinges on the first spring (32), pushes down the operating rod (14), and moves the valve (31) from the valve seat (30). Let go. Therefore, the water in the tank (7) flows into the nozzle cover (12) through the water inlet (17) and the through hole (29), enters the vaporization chamber (4) through the nozzle hole (11), and is vaporized. It is ejected from the steam hole (3). In the above state, the needle (13) is inserted into the nozzle hole (11).
), the gap between the needle (13) and the nozzle hole (11) is large to ensure a sufficient water passage.

When supplying water into the tank (7), the cap (33) must be removed. At this time, even if the operation button (39) is in the raised or lowered position, after removing the cap (33), the cap (33) must be removed. 1 spring (43) actuates the rod (14)
rises and the valve (31) hits the valve seat (3o), causing the water passage (2
6) Occlude.

In the present invention, a support member is provided at the water inlet of the tank, but the same applies to a structure in which a cap is attached directly to the water inlet.

(G) Effects of the Invention As described above, the present invention provides a cap that is removably attached to the water inlet of the tank, and is equipped with a steam/dry switching means for opening and closing the water passage that communicates the inside of the tank with the vaporization chamber. The internal space can be used effectively and the iron itself can be made smaller. Furthermore, the steam/dry switching means can be assembled using the cap alone, making the work easier. Furthermore, since the water passage is automatically closed by the closing means when the cap is removed, it is possible to prevent water from flowing out from the steam hole.
