Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a steam iron for general household use.

BACKGROUND ART Conventionally, in a steam iron of this type in which a tank is detachably attached to the front of the handle, the temperature adjustment structure of the base is as disclosed in, for example, Japanese Patent Laid-Open No. 53-24497.

That is, the temperature control knob is provided below the grip of the handle, and the thermostat connected to and adjusted by this knob is also mounted on the lower base thereof.

Problems that the invention aims to solve However, with this type of configuration, there was a problem that the temperature adjustment accuracy of the base was poor because it was not possible to lengthen the movable piece of the thermostat to increase the temperature adjustment stroke. .

This is due to the following reasons. In other words, since the removable tank is provided in front of the handle, it is difficult to provide the knob in front of the grip of the handle, and it is inevitably provided below the grip of the handle. On the other hand, in thermostats that have a long movable piece as shown in Japanese Patent Publication No. 52-19671, the tank is located above the movable piece, so the knob is attached below the handle as described above. In this case, the operation of the knob cannot be transmitted to the movable piece extending below the tank. The thermostat therefore moves up and down an adjustment shaft that is mounted below the knob and extends upwardly toward the knob. This is because there is no choice but to adopt a so-called seed stacking type.

Therefore, the present invention solves the above-mentioned conventional problems, and improves the temperature adjustment accuracy of the base by increasing the temperature adjustment stroke even in a steam iron with a removable tank that has a knob below the grip of the handle. It is something.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to extend the movable part of the thermostat attached to the rear of the base to the bottom of the tank,
This movable piece and the knob are linked by a substantially L-shaped operating rod.

Effect The effect of this technical means is as follows.
In other words, by making the actuation rod approximately L-shaped,
Since a horizontal part is created that extends rearward from the movable piece, even if a tank is installed above the movable part, it will not interfere with the attachment/detachment operation.Also, since a vertical part is created below the knob, the knob The movement is accurately transmitted to the movable piece via the actuating rod. Therefore, even if the knob is provided below the grip of the handle, it is possible to employ a thermostat in which the movable piece extends below the tank and the temperature adjustment stroke is increased.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In the figure, 1 has a built-in heater;
A base provided with a vaporization chamber 2, and 3 a thermostat with one end fixed to the rear of the upper surface of the base 1. For example, a thermostat having the configuration shown in Japanese Patent Publication No. 19671/1983 is used, and is fixed on the base 1. bimetal 4
The contact 5 is opened and closed by. Reference numeral 6 denotes a movable piece that is urged upward by a spring 7 and extends toward the front of the base 1, and its tip is provided in a substantially L-shape.
It engages with the lower end of the actuating rod 8, which has a horizontal portion 8a and a vertical portion 8b, on the side of the horizontal portion 8a. 9 is base 1
10 is a handle having a grip part 10a attached to the cover 9; 11 is a tank located in front of the handle 10 and detachably provided on the cover 9; , is provided so as to communicate with the vaporization chamber 2 via a nozzle section provided at the bottom. The handle 10 needs to have a grip portion 10a that is long enough for ironing work, and the tank 11 needs to have a sufficient water capacity.
Therefore, the outer shape of the tank 11 has a small upper end surface.
The lower end face is shaped like a large pyramid. Reference numeral 12 designates a temperature adjustment knob attached to the base below the grip portion 10a of the handle 10, and a cam surface 13 is formed on the inner surface of the knob. Touch the top edge of the knob 1
The operating rod 8 is operated up and down by the rotation operation 2 to obtain an adjustment stroke for moving the movable piece 6 of the thermostat 3 in the up and down direction. Reference numeral 14 denotes a support base that supports the knob 12 without wobbling, and is fixed to the base of the handle 10. This support stand 14 has an operating rod 8
A guide hole 15 passing through the vertical portion 8b is integrally provided, and the guide hole 15 faces the cam surface 13. To install the support stand 14 and knob 12,
A protrusion 16 provided on the outer periphery of the lower end of the boss portion of the knob 12
A ring-shaped leaf spring 1 is provided between the
By interposing the knob 7, the knob 12 is made rotatable.

As mentioned above, the movable piece 6 of the thermostat 3 attached to the rear part of the base 1 extends toward the front part of the base 1, and its tip is located below the tank 11. They are linked together via a substantially L-shaped operating rod 8 so that they can be operated by a knob 12 provided below the grip portion 10a of the handle 10. Due to the action of the cam surface 13 due to the rotation of the knob 12, a lateral component force is applied to the operating rod 8 relative to the vertical operating force, but this is regulated by the guide hole 15 of the support base 14. The cam surface 13 is designed to smoothly move the movable piece 6 up and down. Incidentally, if the horizontal portion 8a of the actuating rod 8 is arranged inside the cover 9 as in the embodiment, the upper surface shape of the cover 9 can be simplified and the space for arranging the tank 11 can also be secured.

Effects of the invention As described above, the present invention extends the movable piece of the thermostat attached to the rear of the base to the bottom of the tank, and connects this movable piece to the handle via an approximately L-shaped operating rod. By linking it with the knob attached to the bottom of the grip, the thermostat with a large movable stroke for temperature adjustment allows for highly accurate temperature control, making it possible to iron the fabric at the optimal temperature. In addition to achieving a nice finishing effect, since the knob is provided at the rear of the tip of the movable piece, the lower part of the tank can also be expanded rearward. Therefore, it is possible to secure sufficient tank capacity for ironing and to perform the ironing work efficiently.
