Abstract

PROBLEM TO BE SOLVED: To improve operability by increasing the dripping amount of water by a control lever in the case that a set temperature by an adjustment knob is 'high', reducing the dripping amount of the water in the case that it is 'low' and stopping the dripping of the water to a vaporization chamber regardless of the position of the adjustment knob by the operation of a steam knob. SOLUTION: At the time of setting a base temperature to 'low' by the adjustment knob 42, steam is not generated. However, in the case of requiring the small amount of the steam depending on the kind of fabric or the like, a changeover button 41 is operated, a pressurizing part 38 is pressed down, a dripping shaft 22 is slightly elevated through the control lever 26 in the inclination part 31 of a drive part 32, the small amount of the water is dripped to the vaporization chamber 4 and the small amount of the steam is generated. Also, when the base temperature is set to 'middle' by the adjustment knob 42, an abutting part 39 is pressed down by a guide part 43, the dripping shaft 42 is largely elevated and thus, the increased amount of the steam is generated. At the time, when turning to a dry state, the changeover button 41 is pressed down, a slider 37 is elevated by a spring 34 and steam generation is stopped.

By operating the opening / closing mechanism, the water in the water tank is dripped into the vaporization chamber through the drip nozzle by the opening of the opening / closing mechanism. To evaporate into steam, and the steam is sequentially jetted from the lower surface of the base.

On the other hand, recently, there has been provided a mechanism provided with a mechanism for increasing the amount of steam in order to surely perform wrinkle expansion, and an operation display section thereof is shown in FIG.

The operation of the prior art shown in this drawing is to control the amount of water dripping at the same time as the temperature adjustment in conjunction with a temperature adjustment knob for setting the temperature of the base. The settings when not performing are in different temperature setting positions.

[0005]

In the operation shown in FIG. 8, the temperature setting must be changed when the amount of water dropped is to be changed, which is troublesome.

[0006] Further, there is a method in which the amount of water dripping is controlled by using an electric pump from a water tank of the iron body using a microcomputer. However, this method is expensive and the water in the water tank becomes empty. In this case, the electric pump idled, causing a failure.

The present invention provides a simple operation in which a user can set a desired base temperature and drop water or not by using an adjustment knob without worrying about the amount of water dropped. The steam can be selected, and the steam can be arbitrarily stopped as needed even when the steam is selected.

[0008]

According to the present invention, there is provided a vaporization chamber heated by a heater and a base having a thermostat for controlling energization of the heater, and water provided above the base and dripped into the vaporization chamber. A control lever provided with a storage tank, a handle attached above the base, a switch button for adjusting the amount of water dropped into the vaporization chamber and switching between “steam” and “dry” at the top, and the thermostat A temperature control lever provided with an adjustment knob on an upper portion for setting the temperature of the base by changing the amount of displacement of the base, linking the control lever and the temperature adjustment lever to the adjustment knob, and setting the base set by the adjustment knob. If the set temperature is “high” according to the temperature, increase the amount of water dripped by the control lever,
In the case of "low", in which the amount of water dripping by the control lever is reduced, the switching button stops dripping of water into the vaporization chamber regardless of the position of the adjustment knob.

The upper surface of the chamber (4) is covered with a vaporizing lid (7) to which a tubular packing (6) made of an elastic material and having a drip hole (not shown) is provided.

The thermostat (5) has a contact (8) and a transmission arm (9) connected in series to the heater (3), and changes the position of the transmission arm by an external operation to change the degree of opening of the contact. When the base temperature reaches the set temperature, the contact (8) is opened to cut off the power supply to the heater (3).

A handle (10) has a handle (11) fixed above the base (2) and a back cover (12). A terminal (13) is provided inside the back cover with the thermostat (5). And a power cord (14) connected to the heater (3), and a storage space (15) is formed in front of the grip (11).

A drop control mechanism (18) is provided detachably above the front portion of the base (2) and controls the amount of water dropped into the injection port (17) and the vaporization chamber (4).
The drip control mechanism (18) includes a nozzle body (19) having a nozzle hole (not shown) that is tightly connected to the cylindrical packing (6), and a pressing spring (20). ), A drop shaft (22) urged upward by a push-up spring (21), which is urged downward and has a lower resilience than the push-down spring, and one end (23) of the drop shaft is relatively moved. Hang on the upper part and connect the other end (24) to the tank (1).
6) Exposed to the outside from the side wall,
5) a control lever (26) pivotally supported by
One end of the control lever (26) is hooked between the push-down spring (20) and the push-up spring (21), and the other end is free.

(27) A temperature which penetrates part of the handle (10) in the vertical direction, the upper end (28) faces the storage space (15), and the other end is engaged with the transmission arm (9). The adjusting lever is urged upward by the pushing force of the transmission arm.

Numeral (29) is a position holding mechanism for the dropping shaft (22), which is constantly urged upward by a coil spring (30) and tilts laterally to contact the other end (24) of the control lever (26). A sliding rod (33) including a driving part (32) having a part (31); and a rotor (3) rotatably connected to an upper part of the sliding rod and urged upward by a spring (34).
5) a slider (37) meshingly connected to an upper portion of the operating rod, and changing the meshing position of the operating rod (36) with the vertical movement; A pusher (40) provided on the upper part of the hand and having a pressing part (38) and an abutting part (39). ) Drops and closes the nozzle hole, resulting in “dry” (steam stopped)
And the control lever (2
In step 6), the drip shaft (22) is pulled up to open the nozzle hole to make “steam” (steam generation).

(41) is a switch button for "steam" and "dry" provided on the front side of the grip (10) and having one side located above the pressing portion (38) of the slider (37). The slider (37) is pushed down by repeating the pushing operation, and the pushing is repeated to select a desired position.

Reference numeral (42) denotes an adjustment knob slidably mounted in the front-rear direction in the storage space (15) on the front side of the grip (10). ) Slides to move the drip shaft (22) up and down to set the steam to "small" or "increase", a first guide portion (43) having a large inclination, and the temperature control. By changing the position of the transmission arm (9) by applying the upper end of the lever (28), the base temperature is set to "off", "low", and "medium" and "high" as shown in FIG. And a second guide portion (44) having a gentle slope for setting a desired temperature.

Therefore, when the adjustment knob (42) sets the base temperature to "low", the first guide portion (43) cannot push down the contact portion (39) and no steam is generated. When the button (41) is pressed, the pressing portion (38) can be slightly pressed down, and the drip shaft (22) rises slightly, and the temperature becomes "low" and "small amount steam". (This is the state shown in FIG. 5 and will be described later in detail).

The control knob (42) sets the base temperature to "medium".
When the first guide portion (43) is set to the contact portion (3)
9) is sufficiently depressed to raise the drip shaft (22) greatly to increase the amount of dripping into the vaporization chamber (4), and the second guide portion (44) depresses the transmission arm (9) to heat the heater (3).
The power supply time to the battery is increased, and the temperature becomes "medium" and "increased steam". (It is the state of FIG. 6 and will be described later in detail).

The temperature control knob (42) raises the base temperature to "high".
When the first guide portion (43) is set to the contact portion (3)
In a state in which 9) has been sufficiently depressed and the amount of dripping into the vaporization chamber (4) has been increased, the second guide portion (44) further depresses the transmission arm (9) to energize the heater (3). By increasing the time, the temperature becomes "high" and "increased steam". (This is the state shown in FIG. 7 and will be described later in detail).

Next, the operation will be described. First, when the base temperature is set to “low”, when the temperature is set to “low”, the base temperature is relatively low.
As shown in (1), the first guide portion (43) of the adjustment knob (42) does not push down the contact portion (39) and does not automatically generate steam. However, soft steam may be required depending on the type of fabric or its drying condition. In such a case, the switching button (41) is pressed to press the pressing portion (3).
8) By pressing down, the entire presser (40) is pressed down, and the inclined portion (31) of the drive section (32) slightly presses down the other end of the control lever (26), and the drip shaft (22).
Is slightly raised to slightly open the nozzle hole, and a small amount of water is dropped into the vaporization chamber (4) to generate "a small amount of steam".

When the base temperature is set to "medium",
Due to the relatively high base temperature, it has the ability to generate more steam. From this, when the temperature control knob (42) is moved to the "middle" position as shown in FIG. 6, the transmission arm (9) is pushed down and the heater (3) is turned off.
And the first guide part (43)
Automatically pushes down the contact portion (39) and slides the sliding rod (33).
Is greatly depressed, and the other end of the control lever (26) is further depressed to greatly raise the drip shaft (22), open the nozzle hole largely, and drop much water into the vaporization chamber (4).

In this state, to switch to the "dry" state in which the generation of steam is stopped, the switch (41) is depressed so that the presser (40) is depressed, and the slider (37) held at the lowered position is held. ) Is released from the holding state, and is raised by the spring (34). One end of the control lever (26) is pressed down and the drip shaft (22) is pressed down by the spring (20) to close the nozzle hole and set to "dry".

Subsequently, when the base temperature is set to "high", the transfer arm (9) is set to the above "medium" with the movement of the temperature control knob (42) to the "high" position. , The energization time to the heater (3) is extended to increase the base temperature, and the first guide portion (43) automatically pushes down the contact portion (39) as shown in FIG. As in the case of the above-mentioned "medium" setting, the nozzle hole is largely opened to obtain "increased steam".

In this setting state, the adjustment knob (4
Depressing the switch button (41) irrespective of the position of 2) can stop the generation of steam and make it "dry".

[0026]

As described above, according to the present invention, the control lever and the temperature control lever are linked to the adjustment knob, and the set temperature is set to "high" according to the base temperature set by the adjustment knob.
In the case of, increase the amount of water dripped by the control lever,
In the case of reducing the amount of water dripping by the control lever, the steam knob stops dripping water into the vaporization chamber regardless of the position of the adjustment knob. The amount of steam generated can be automatically changed according to the type of fabric, and the operation is simplified, and even if steam generation is set by the adjustment knob, the generation of steam is stopped by the switch button, And a use form suitable for a dry state.

That is, when the fabric is in a semi-dry state, it can be brought into a dry state by raising the base temperature in a state without steam.
