Description

[Detailed explanation of the idea] (1) Technical field of invention The present invention relates to a steam iron.

(2) Prior art and its problems Generally, a steam iron has a vaporizing chamber formed in the base, water is dripped into this vaporizing chamber from a water storage tank by a drip nozzle, and the steam generated here is communicated to the vaporizing chamber. It is made to eject from the spout of the base.

Then, during use, after adjusting the temperature of the base to a temperature suitable for steam generation using the adjustment dial of the temperature controller, the dripping nozzle is opened to allow water to drip into the vaporization chamber of the base to generate steam. ing. In this case, a base temperature adjustment operation and a water dripping operation are required.

Therefore, a device has been proposed in which when the adjustment dial is set to steam, temperature control and opening/closing of the dripping nozzle are performed simultaneously using a cam that is linked to the dial.

However, according to the conventional method, when operating the operating part that performs temperature control and opening/closing of the dripping nozzle at the same time, each setting part is formed continuously, so the operating part is easy to move, resulting in some misoperation. However, there is a risk that it may be set to an undesired state.

Furthermore, conventionally known devices are equipped with a click mechanism that clicks in correspondence with each fiber scale when the adjustment dial is rotated to a desired state.

However, the conventional adjustment dial with a click mechanism requires a separate click mechanism, which complicates the structure and increases cost.

(3) Purpose of the invention The present invention is an attempt to solve the above-mentioned problems, and is a steam iron in which temperature setting and steam and dry settings can be set simultaneously by operating one operating body. It is an object of the present invention to provide an apparatus that can perform a click operation at low cost and without impairing reliability without providing a click mechanism.

(4) Structure of the invention The present invention includes a heater provided on the base, a vaporizing chamber and a spout communicating with the vaporizing chamber, a handle body and a water storage tank provided on the base, and a water storage tank provided with a handle body and a water storage tank. A drip nozzle for supplying water to the vaporization chamber is provided, a valve lever for opening and closing the drip nozzle is provided for vertical movement, and a temperature controller is installed on the base to adjust the temperature of the base using a heater. An operating rod for controlling the temperature regulator is connected to the temperature regulator, a cam having a cam surface for vertically moving the valve rod and the operating rod is provided on the handle body, and an operating body is connected to the cam. On one of the cam surfaces that opens and closes the dripping nozzle by moving the valve rod up and down, the valve rod is pressed down to form a dry region where water does not drip, and the valve rod is raised to form a dry area where water is dripped. The other cam surface that forms a steam region and controls the temperature regulator by moving the operating rod up and down forms a temperature setting section corresponding to each fiber, and the operating rod is attached to the one cam surface. At least one concave portion is formed at a position where the valve lever comes into contact when the operating body is aligned with the temperature setting portion by operating the cam, and a click operation is performed between the cam and the valve lever. It is.

(5) Embodiment of the invention An embodiment of the invention will be described below with reference to the drawings.

In Fig. 1, reference numeral 1 denotes a base formed by aluminum die-casting.A heater 2 is embedded in this base 1, and a vaporization chamber 3 is formed on the upper surface of the base 1, and is connected to the vaporization chamber 3. A spout 4 is provided on the lower surface of the base 1. A lid plate 5 is attached to the upper surface of the vaporization chamber 3.

A cover 6 is attached to the base 1, a heat shield plate 7 is provided on the cover 6, a handle body 8 is watertightly connected to the heat shield plate 7, and a water storage tank 9 is disposed within the handle body 8. is formed, and a handle 10 is formed on the upper part of the handle body 8. A water inlet 11 is formed at the upper front surface of the water storage tank 9, and a water inlet cover 12 is attached to the water inlet 11 so as to be openable and closable.

Further, a drip nozzle 13 facing the vaporization chamber 3 is attached to the lower part of the water storage tank 9, and a valve rod 14 penetrating through the water storage tank 9 is provided to the drip nozzle 13 so as to be movable up and down. The rod 14 is always urged upward by a coil spring 15.

Further, an automatic temperature regulator 16 is mounted on the base 1 to control the temperature of the base 1 by the heater 2, and a movable adjustment part of the temperature regulator 16 is connected to the water tank 9 in the handle body 8 in a watertight manner. The lower end of an operating rod 17, which is provided so as to be vertically movable through the isolated space, is connected to the operating rod 17.

Furthermore, a support plate 18 is attached to the upper part of the handle body 8, and a cam 20 is attached to this support plate 18 by a shaft 19.
is rotatably mounted on a shaft, and the cam 20 is formed with cam surfaces 21 and 22 that abut the upper ends of the valve rod 14 and the operating rod 17. A lever 23 as an operating body extends integrally from the cam 20, and an indicator knob 24 is attached to the front end of the lever 23. A cap 25 is attached to the handle body 8 so as to cover the cam 20, and a display plate 26 is affixed to the upper surface of the cap 25 so as to face the rotating part of the indicator knob 24.

Then, when the lever 23 is rotated, the cam 20
rotate together, and the valve rod 14 moves up and down in response to changes in the height of one of the cam surfaces 21, opening and closing the drip nozzle 13 to switch between the steam state and the dry state, and the other cam surface 22. The operating rod 17 moves up and down in response to changes in height, and operates the temperature regulator 16 to adjust the temperature at which the base 1 is heated by the heater 2.

Both cam surfaces 21 and 22 of the cam 20 are
They are formed in a relationship as shown in FIG. That is, by moving the valve rod 14 up and down, the drip nozzle 13
One cam surface 21 that opens and closes the valve rod 1
A dry region in which water is not dripped by pressing down the valve 4 and a steam region in which water is dripped by raising the valve rod 14 are continuously formed. The other cam surface 22, which controls the temperature regulator 16 by moving the operating rod 17 up and down, has a range from the lowest temperature to the highest temperature, for example, for each fiber such as chemical fiber, wool, cotton, linen, etc. Corresponding temperature setting sections are sequentially formed. Furthermore, the one cam surface 21
, when the lever 23 is rotated and the indicator knob 24 is aligned with each temperature setting section, the valve lever 1
A concave portion 27 that bulges upward is formed at a position where the upper end portion of 4 abuts. This recess 27 is formed to a depth such that when the upper end of the valve stem 14 fits therein, the drip nozzle 13 will not be in the open state when the indicator knob 24 is in the dry iron area.

As shown in FIG. 3, the display board 26 displays "dry iron" and "steam iron" areas and temperature setting sections corresponding to each fiber in accordance with the control by the cam 20. There is.

That is, if you want to use it as a dry iron, by matching the knob 24 to the fiber name in the "dry iron" range, you can obtain the temperature and dry iron condition suitable for that fabric.
If you want to use it as a steam iron,
If the knob 24 is set in the "steam iron" range, a steam iron condition can be obtained.

Furthermore, when adjusting the indicator knob 24 to each fiber scale, the upper end of the valve rod 14 engages with the recess 27 of the cam 20, and a click operation occurs between the cam 20 and the valve rod 14, so that the lever 23 is rotated. It is also moderate and easy to adjust the scale.

In addition, in the above embodiment, a lever is shown as the operating body for the cam, but a dial may also be used.

Further, although the water storage tank is shown as being formed by the handle body and the heat shield plate, a separate tank may be used.

Further, although the temperature of the steam iron area is variable, it may be set to a constant temperature. Furthermore, in the steam iron area, the fiber name that matches the temperature of the hanging surface of the base at that time is displayed.
The fiber name does not need to be displayed.

(6) Effects of the invention According to the invention, when temperature setting and steam and dry settings are simultaneously performed using the operating body, appropriate moderation is provided by the click operation, there is less risk of malfunction, and moreover, the click operation can be cammed. Since the click operation is performed between the valve lever and the valve lever, it is possible to perform an inexpensive and reliable click operation without providing a special click mechanism.
