[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron having a handle and a circuit board and operation buttons.

[0002]

2. Description of the Related Art A conventional iron having a circuit board arranged on a handle body, particularly a grip portion thereof (see, for example, US Pat. No. 4,347,4).
No. 28) has an operation part for generating steam or spraying the front end of the grip part, so that the circuit board is arranged behind the operation part. .

[0003]

However, in the above structure, the mounting position of the circuit board is restricted, so that the circuit board cannot be placed in front of the handle body, and the space inside the handle body cannot be effectively used. Also, LED on the circuit board
There is also a problem in that the display becomes difficult to see because the display is located at the rear when the display is arranged. Then, this invention makes it a subject to solve the said problem.

[0004]

In order to solve the above problems, the present invention provides a circuit board accommodated in a handle body, a water tank provided below the circuit board, and a water tank provided in the water tank. A water supply device that draws in water from the water tank and discharges it to the outside, an operation button that is partially exposed to the outside of the handle body and the other part is supported by the handle body and is operated up and down, and the operation button and the water supply device are connected together An operating rod and a temperature indicator provided on the circuit board in front of the operating button are provided, and the operating rod penetrates the circuit board so as to divide the electric parts on the circuit board into front and rear.

[0005]

According to the present invention, the parts on the circuit board are arranged in front and back, and the operating rod is arranged so as to pass through the section of the circuit board. The board can be placed, and parts such as the display can be mounted in a position that is easy to see in the front. Further, the operating rod is located in a sparse part of the electric component, and when operating the operating button, it is possible to secure a region where the operating rod or the operating button can operate without hitting the electric component.

The handle body (6) is, as shown in FIG.
A fixing part (6) fixed to the rear part of the upper surface of the base body (5).
a), a grip portion (6b) and an overhanging portion (6c), and forming a bulging portion (6d) for locking the water tank (7) and forming an inclined surface portion (6e). ing. A front portion of the inclined surface portion (6e) is stepped down substantially horizontally to form a step portion (18), and an engaging hole (20) is formed in the step portion (18). The bulging portion (6d) and the base body (5) form a storage space (H). Light emitting diodes (D), (D), (D), and (D) for displaying a desired temperature are arranged inside the overhanging portion (6c), and a touch switch (21) for selectively displaying the light emitting diodes is arranged. The operation button (22) is slightly exposed.

Various electric parts (23), (23) and (23) are provided inside the grip portion (6b) and a circuit board (24).
It is arranged through. The electric parts mounted on the circuit board (24) are arranged such that the light emitting diode (D) group and the other electric part (23) group are separated from each other at a predetermined distance in the front and rear. The operation button (22) is arranged in this divided portion, and an operation rod (22a) that links the operation button (22) and a water supply device (40) described later is vertically penetrated through the circuit board (24). Are arranged. With this configuration, when the operation button (22) is operated, the operation button (22) and the operation rod (22)
It is possible to prevent a situation in which a) hits an electric part and interferes with the operation, and the circuit board (24) is provided over the entire length of the space inside the handle body (6) regardless of the position of the operation button (22). The display device such as a light emitting diode or the like can be arranged in a front easy-to-see position.

As shown in FIG. 7, the water tank (7) has a U-shaped planar shape, and a pair of tank extension portions (abutting against the bulging portion (6d) and the inclined surface portion (6e). 7a)
Along with the formation of (7a), an engaging portion (7b) that engages with the stepped portion (18) is formed. The water tank (7)
An opening / closing lid (26) for injecting water is provided in the front part of the upper surface of the above, and the opening / closing lid (26) is pressed down by the inclined surface portion (6e) of the handle body (6). A lock rod (27), which is engaged with and disengaged from the engagement hole (20), is freely retractable through a first spring (28) on the upper surface of the water tank (7), and the tank (7) is internally provided. An opening and closing rod (30) is formed on the bottom surface of (1) to open a drip hole (29) communicating with the injection hole (14) and is vertically provided via a second spring (31). (32) is a lock release button that pushes down the lock rod (27) downward to release the engagement with the engagement hole (20), a part of which is exposed on one side surface of the engaging portion (7b). The third spring (3
When pressed against 4), the lock rod (27) is pressed down against the first spring (28), and when released, the springs (34) and (28) spring out to their original positions. It is a thing. Further, (36) is provided with the leaf spring (37) and the second spring (31) through the opening / closing rod (3).
Open / close button that moves 0) up and down, the 4th spring (3
8) is always urged to project outward and is pressed against the small fourth spring (38) to maintain the pressing inside the engaging portion (7b). Is formed. That is, when the open / close button (36) is pressed, first the hooking portion (36a) is caught inside the water tank (7), and the open / close rod (30) is pushed down by the leaf spring (37) to lower the open / close rod. The lower end of (30) closes the drip hole (29). When the opening / closing rod (30) is returned to its original position, the drip hole (29) will be opened. The opening / closing button (36) is disposed on the other side surface of the engaging portion (7b) of the water tank (7) so that a part of the opening / closing button (36) is exposed. It is considered so that it will be at the position where it can be picked.

Reference numeral (40) is a water supply device which sucks the water in the water tank (7) and directly discharges it to the outside by pressing the operation button (22). The water supply device (40) is provided so as to be exposed to the outside of the water tank (7). Discharge part (41) and communication pipe (4
2), suction pipe (43), ball check valve (44)
And a piston part (45) which is moved up and down by the button (22).

[0012]

As a part of the operation button is exposed to the outside of the handle body and the other part is supported by the handle body, no stress is applied to the circuit board even when the operation button is operated up and down. Further, since the operating rod is connected to both the operating button and the water supply device and the operating rod penetrates the circuit board, stress is applied to the water supply device when the operating button is pressed. Therefore, since no stress is applied to the circuit board, there is no risk of damage. Further, the operating rod is arranged so as to penetrate the front and rear sections of the electric component on the circuit board, and the indicator is provided on the circuit board in front of the operation button. Therefore, the display is arranged in a front easy-to-see position, and the display becomes easy to see. Further, since the operation lever is directly operated by pressing the operation button and moving the operation rod, drainage can be performed without using another opening / closing device and the like, and the drainage device can be simplified.
