Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a steam iron equipped with a removable tank for use in general households.

Structure of the conventional example and its problems Conventionally, this type of steam iron
As shown in Publication No. 4497, the tank forms the outer shell of the iron attached to the front part of the iron body, and is made of partially transparent or translucent plastic so that the amount of water inside can be easily checked. Usually, the tank is installed at intervals on the top side of the iron body.

This is to prevent the tank from being overheated by heat from the base, but it also raises the bottom of the tank and extends it backwards to compensate for the reduction in tank capacity. It is set up.

As a result, the tank is inconvenient and cannot be attached or detached unless it is moved in two directions, making it extremely inconvenient to use.

In addition, the lower end of the nozzle member at the bottom of the tank is directly fitted and connected to the opening of the vaporization chamber, which is heated to a high temperature, so the nozzle member itself is heated to a high temperature and the tank requires the use of expensive materials. In addition to being expensive, the thermal influence on the nozzle member also makes the dripping of water unstable.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, improves the operability when attaching and detaching the tank, and rationally eliminates thermal effects on the tank.

Structure of the Invention In order to achieve the above object, the present invention includes an iron body with a handle attached to the top side of the base having a vaporization chamber, and a tank detachably attached to the iron body. By providing an opening in the tank, attaching a nozzle member connected to the vaporization chamber to this opening, and fitting this nozzle member into an opening in a heat shield plate provided on the upper surface side of the base, the tank can be easily installed. This not only restricts the position of the tank but also prevents the nozzle member from overheating.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a base with a built-in heater 2 and a vaporization chamber 3 formed therein, 4 is a steam ejection hole that releases the steam generated in the vaporization chamber 3, and 5 is a base installed on the base 1 and facing the vaporization chamber 3. The cover 6 is a flexible cylindrical member that protrudes from the recess 5a and is attached to the vaporization chamber 3, and is made of a heat-resistant material such as silicone rubber. .

Reference numeral 7 denotes a heat shield plate attached to the cover 5, which forms an open lower part a facing the recessed part 5a, and has an inclined part 7b extending upwardly on its upper surface side.

8 is a handle installed on the cover 5; 9 is a tank that can be attached to and detached from the iron main body A; the bottom part has a nozzle part 9a that communicates with the vaporization chamber 3 through a cylindrical member 6; An opening/closing rod 9b is provided opposite to the nozzle portion 9a, and this opening/closing rod 9b is always urged upward by a spring 9C.

Further, an operating button 9d protruding from the upper surface of the tank 9 is provided at the upper end of the opening/closing rod 9b, and the nozzle portion 9a can be opened and closed by vertically moving the operating button 9d.

10 is an O on the inner peripheral edge of the opening 11 provided at the bottom of the tank 9.
A nozzle member is removably attached via an annular backing 10a such as a ring, which fixes the nozzle portion 9a, and is provided with a rib 10b protruding toward the base 1 so as to surround the nozzle portion 9a.

The annular backing 10a is made of a heat-resistant and sealable material such as silicone rubber, and is attached to the outer peripheral wall of the nozzle member 10 so as to surround it, and is compressed between it and the inner peripheral edge of the opening 11. Sealed by positioning.

When attaching the tank 9 to the iron body A, use the rib 10
By fitting b into the open lower a, the nozzle part 9a
A state of connection between the cylindrical member 6 and the cylindrical member 6 is obtained.

The surface of the tank 9 constitutes the outer shell of the iron, and the bottom surface is provided in substantially the same shape as the outer shells of the heat shield plate 7 and the cover 5, and the tank 9 itself has a substantially trapezoidal shape.

Moreover, the nozzle member 10 is fitted into the open lower part a and is not exposed to the surface of the iron.

12 is a locking portion protruding toward the handle 8 side on the rear surface of the tank 9;
Reference numeral 3 denotes a locking device provided on the handle 8 side facing this locking portion 12, which is always urged toward the tank 9 side by a spring 13a, and is engaged with the locking portion 12 to hold the tank 9 in the iron body A. It is to be held in the state that it is attached to.

When removing the tank 9, the locking device 13 is slid in the direction of the arrow A to release the engagement with the locking portion 12, so that the tank 9 can be removed in the direction of the arrow.

Reference numeral 14 denotes a spring device attached to the heat shield plate 7, and its biasing force acts in a direction to push up the tank 9 from below when the tank 9 is attached to the iron main body A.

In the above configuration, when the tank 9 is attached to the iron main body A, the tank 9 is operated in the direction of the arrow, and the rib 10b of the nozzle member 10 is fitted into the open lower a using the inclined portion 7b of the heat shield plate 7 as a guide.

The position of the nozzle part 9a and the cylindrical member 6 is regulated so as to be coupled and liquid-tightly connected to the vaporizing chamber 3, and the locking device 13 is engaged with the locking part 12, so that the iron main body A It is kept attached to the

Further, the tank 9 is fitted into the open lower a of the heat shield plate 7 via the nozzle member 10, so that the nozzle part 9a and the cylindrical member 6
are guided to positions corresponding to each other, and the base 1
Since a heat insulating space is formed between the tank 9 and the nozzle member 10, overheating of the tank 9 can also be prevented.

In the above embodiment, the nozzle member 10 is provided with a rib 10b that surrounds the nozzle portion 9a and is fitted into the open lower a, but even if the member fitted into the open lower a is the outer wall of the nozzle member 10, It may be part of.

In short, when the tank 9 is attached to the iron main body A, it is only necessary that the nozzle member 10 to which the nozzle 9a is attached can be inserted into the opening lower a to regulate its position.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the nozzle member attached to the bottom of the tank is fitted into the opening of the heat shield plate provided on the upper surface side of the base, so that the nozzle part and the cylindrical member are connected to each other. are set in a coupled state with their positions regulated, making it extremely easy to attach the tank, and also to prevent misalignment between the nozzle part and the cylindrical member, resulting in a reliable seal.

In addition, the tank and the vaporization chamber are connected and sealed via the nozzle part provided on the nozzle member and the flexible cylindrical member, and the nozzle member is fitted into the opening of the heat shield plate outside the vaporization chamber. , it is possible to prevent adverse effects on the tank due to heat from the base.
