Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a steam iron with a detachable tank.

BACKGROUND ART Conventionally, in this type of steam iron, as shown in Fig. 3, a tank 1' is configured to be detachable from the iron main body 2' in order to facilitate the work of filling and draining water into the tank. 1′
The iron body 2' was attached to the iron body 2'.

Problems to be Solved by the Invention As shown in Fig. 3, the attachment/detachment of the tank in these conventional products requires sliding in the horizontal or diagonal direction, as well as connection with the vaporization chamber. Therefore, vertical movement was required to maintain the fit between the tank and the iron body.
In this way, the ease of attaching and detaching the tank was extremely poor, as complicated operations had to be performed to attach and detach the tank, and it was not possible to maintain the fit between the two unless the specified direction and procedure were followed. .

The present invention solves these problems, and aims to simplify the operation of attaching and detaching the tank by sliding the tank in one direction substantially parallel to the ironing surface of the iron base.

Means for Solving the Problems In order to achieve the above object, the present invention includes an iron main body having a base forming a vaporizing chamber and a handle attached above the base, and an iron main body that is detachably attached to the iron main body. and a tank for storing water to be supplied to the vaporization chamber, a normally closed valve mechanism that opens and closes a water inlet provided at the bottom of the tank, a seal member that connects the water inlet and the vaporization chamber, and the valve mechanism. an opening body that is provided opposite to the tank and holds the valve mechanism of the tank in an open state in response to attachment of the tank to the iron body, and the opening body and the sealing member are urged toward the tank side. The apparatus includes a protrusion and a cam device that integrally displaces the opening body, the sealing member, and the protrusion downward in response to attachment and detachment of the tank to and from the iron body.

Function According to the above configuration, the tank can be reliably connected by the slide insertion operation into the iron body. A pressing member operates in contact with the cam surface at the bottom, and pushes up the sealing member at a position where the opening of the tank and the vaporization chamber are connected, completely connecting the opening and the vaporization chamber.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In Figures 1 and 2,
A water tank 1 is detachably attached to the front of the iron body 2. A water inlet 3 and a valve mechanism 4 are provided at the bottom of the water tank 1, and the valve mechanism 4 is elastically biased by a valve spring 5 to a valve body 6 in a direction to close the water inlet 3. ing. In addition, an open body 8 is urged upwardly by an open body spring 9 and protrudes from the lower surface of the water inlet 7 on the side of the iron body 2 facing the iron body 2, and around this open body 8, the water tank 1 is It has a packing 10 that is a sealing member that elastically maintains close contact with the water inlet 3, and the opening body 8 is a pressing member that moves in contact with a cam-shaped part 11 provided at the bottom of the water tank when the water tank 1 is attached or removed. The protrusion 12 is integrally formed.

However, when the water tank 1 is attached to the iron body 2, the opening body spring 9 of the opening body 8 is connected to the valve spring 5.
Since it is made stronger than the valve mechanism 4 of the water tank 1.
is pushed up, and the valve body 6 is also pushed up, and the water inlet 3 and the water inlet 7 are integrally connected, and water from the water tank 1 is supplied to the base vaporizing chamber 13 of the iron body 2 via the water conduit 14. In this configuration, the operations immediately before the slide insertion operation of the water tank 1, at the time of setting, and at the time of removal will be explained using the figures in FIG.
Figures a, b, and c show the cross-sectional configurations of the water inlet and the water guide port, and d, e, and f of the same figure show the relationship between the respective cam-shaped portions 11 and the projections 12 that come into contact with each other. Figures a and d show the state immediately before setting, and a protrusion 12 is formed integrally with the opening body 8 in contact with the protrusion of the cam-shaped part 11 provided at the bottom of the water tank 1.
is pushed down and therefore packs 10
The opening body 8 is also pushed down at the same time, allowing the water tank 1 to be inserted without contacting the vicinity of the water inlet 3 at the bottom of the water tank 1 or the valve mechanism 4. When the set state as shown in b and e of the same figure is reached, the protrusion 12
enters the concave portion of the cam-shaped portion 11, so that the packing 10 and the opening body 8 hit the valve spring 5 and are pushed up by the force of the opening body spring 9, so that the packing 10 comes into close contact with the bottom of the water tank 1 and does not pass through. Mizuguchi 3
and the water inlet 7 are connected together. Furthermore, when the two are separated as shown in c and f of the same figure, the valve mechanism 4 of the water tank 1 is biased by the valve spring 5 to close the water passage port 3 of the valve body 6, so that the water This prevents the water in the tank 1 from falling. With such a configuration, as shown in FIG. 1, a finger pressing part 15 can be formed on the front part of the iron main body 2, and the tank can be attached and detached by horizontally sliding the water tank 1. I can do it. In addition, in this example, an example was shown in which the tank and the vaporization chamber were connected via a water conduit.
May be directly combined. Further, the steam/dry switching device may also be built into the tank. In short, it is sufficient if the sealing member can be moved in conjunction with sliding movement with the tank.

Effects of the Invention As described above, the steam iron of the present invention includes an iron main body having a base in which a vaporizing chamber is formed and a handle attached above the base, the iron main body being detachably attached to the iron main body, and the vaporizing chamber A tank for storing water to be supplied to the tank, a normally closed valve mechanism for opening and closing a water inlet provided at the bottom of the tank, a sealing member for connecting the water inlet and the vaporization chamber, and a seal member provided opposite to the valve mechanism. an opening body that holds the valve mechanism of the tank in an open state in response to attachment of the tank to the iron body; a protrusion that urges the opening body and the sealing member toward the tank side; By including a cam device that integrally displaces the opening body, the sealing member, and the projection body downward in response to attachment and detachment of the tank to and from the iron body, the tank is made substantially parallel to the hanging surface of the base of the iron body. It can be easily attached and detached by a simple sliding operation in one direction. Also,
The sealing member is not affected by the action of attaching and detaching the tank, preventing twisting and wear of the sealing member, and ensuring the sealing connection between the tank and the iron body over a long period of time.
