Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ironing device for supplying steam generated by a steam generator to an iron body to smooth wrinkles in clothes and the like.

[0002]

2. Description of the Related Art Conventionally, this type of ironing device has a structure as shown in FIGS. 6 and 7, for example. That is, the operation lever 102 for opening and closing the steam valve 101 is pushed down to move the valve body 103 up and down, thereby changing the steam passage area depending on the position to control the steam supply amount to the steam chamber.

[0003]

However, in such a structure, since the steam valve 101 is arbitrarily operated from the fully closed state to the fully opened state by manually operating the operation lever 102, the supply amount of the steam is controlled steplessly. While it has the advantage that
There was a problem that the optimum amount of steam could not be spouted for the type of fabric to be ironed, and for thick and thin fabrics.

That is, the amount of steam ejected is determined by the steam valve 1.
The position of the operation lever changes depending on the opening degree of 01, so that the adjustment of the operation lever position has been performed by the experience of the ironing operator. Therefore, the amount of steam was uncertain, and the variation was further caused by the operator.

Therefore, the present invention makes it possible to supply the optimum amount of steam to the ironing cloth regardless of who operates it, regardless of the experience of the ironing operator, and to simplify the control device. A first object is to obtain an ironing device that can be used. The second purpose is to obtain an ironing device that can prevent the occurrence of drainage.

[0006]

In order to achieve the above first object, the present invention provides a control device for controlling the supply of steam from a steam generator to an iron body, which is a body having a pair of input / output ports. And a steam passage formed by connecting an input port and an output port to the body, and a plurality of valve devices for opening and closing the steam passage.

In order to achieve the second object, the present invention provides a control device for controlling the supply of steam to the iron body.
It is composed of a body having an input port on the lower side and an output port on the upper side, a steam passage formed by connecting the input port and the output port to the body, and a plurality of valve devices for opening and closing the steam passage from the side. A passage is formed substantially below the bottom of the valve chamber of the valve device to communicate with the input port.

[0008]

In the ironing device of the present invention, the steam passage area changes when the combination of operating the plurality of valve devices is changed by the configuration of the control device, and the steam amount corresponding to each passage area is reliably obtained. Since the plurality of valve devices are configured in the body having the pair of input / output ports, a new connecting member for connecting the valve devices to each other is unnecessary. Therefore, installation of the control device in the steam generator,
Also, the connection between the hose and the control device can be easily performed.

Further, since the passage is formed substantially below the bottom of the valve chamber of the valve device and communicates with the input port, the hot water dewed in the valve chamber and adhering to the inner surface is attached to the bottom of the valve chamber by its own weight. The flow passes through the passage and the input port formed substantially downward from the gathering bottom and is returned to the steam generator. Therefore, even if the steam passage is subsequently opened by the control device and the steam is ejected, a good-quality steam with less water content, that is, less drainage can be obtained.

In the steam chamber 11, a steam ejection hole 12 is provided. Reference numeral 13 is a steam generator for generating steam. Supply control of the generated steam is performed by the controller 14, and steam is supplied to the steam chamber 11 of the iron main body 10 via the hose 15 and the connection fitting 16.

Reference numeral 17 denotes an operating means for controlling the opening / closing of the control device 14, which is composed of a plurality of switches 17a, 17b, 17c and is electrically connected to the control device 14 via a power supply control box 18.

Next, the control device 14 will be described.
Reference numeral 19 denotes a body having a plurality of input ports 21a and 21b connected to the steam outlet 20 of the steam generator 13 and an output port 22 connecting the hose 15. The body 19 has input ports 21a and 21b and an output port. A steam passage 23 that connects the two 22 is formed.

One input port 21a is used for the steam generator 1
3 and the other input port 21b is screw cap 2
4 is airtightly closed, and the body 19 is also airtightly attached with valve devices 14a, 14b and 14c which are composed of a plurality of solenoid valves for opening and closing the steam passage 23.

Then, each of the valve devices 14a, 14b, 1
4c is a passage 26a, 26 of each valve seat 25a, 25b, 25c independently of each switch 17a, 17b, 17c of the operating means 17 provided on the iron body 10.
electrically connected to open and close b, 26c,
The passages 26a, 26b, 26c of the respective valve seats 25a, 25b, 25c for opening and closing the respective solenoid valves 14a, 14b, 14c.
Areas are different from each other, for example, in three stages of small, medium and large.

Next, the operation of the structure of this embodiment will be described. First, turn on the switch 17a of the operating means 17.
Then, the solenoid valve 14a of the control device 14 opens the valve seat 25a, and the steam of the steam generator 13 passes through the valve seat 25a opened from the input port 21a, the passage 26a, the hose 15,
It is supplied to the steam chamber 11 through the connecting fitting 16 in sequence and is ejected from the ejection hole 12.

The amount of steam at this time is determined by the sectional area of the passage 26a of the solenoid valve 14a, and the passage 26a
a is a passage 2 opened by the other solenoid valves 14b and 14c
Since it is set smaller than 6b and 25c, and the other solenoid valves 14b and 14c are closed, a small amount of steam can be obtained.

Similarly, when the switch 17b is turned on, the solenoid valve 14b is opened and a medium amount of steam is obtained.
When the switch 17c is turned on, the solenoid valve 14c is opened and a large amount of steam is obtained. In this way, when the operating means 17 and the valve device of the control device 14 are electrically connected in pairs, if the number of pairs is n, the amount of steam that can be selected will be (n remainder of 2 -1).

Further, when both the switches 17a and 17b are turned on, the steam passage area at this time is determined by the solenoid valve 14
The sum of the areas of the passages 26a and 26b of a and 14b gives a small + medium amount of steam. Therefore, in the ironing work, the operator only needs to select and operate the switches 17a, 17b, 17c of the operation means 17,
It is possible to reliably obtain a steam amount suitable for various fabrics.

Further, in the installation work of the control device 14, each valve device 14 for switching the steam amount to the body 19 having the pair of input / output ports 21a and 22.
Since a, 14b, 14c are integrally configured, the valve devices are connected to each other and each valve device 14a, 14b, 14c is connected.
To the steam generator 13, and each valve device 14
A new connecting member is unnecessary for connecting the a, 14b, 14c and the hose 15.

Therefore, since the connecting work can be omitted accordingly, the control device 14 can be installed in the steam generator 13 and the hose 15 can be installed in the control device 14 quickly and easily.

In the above embodiment, the input port 21a is used.
Although the configuration in which the steam generator 13 is connected to the side has been described, the steam generator 13 may be connected to the input port 21b side and the input port 21a may be closed with the screw cap 26. In this case, it is convenient when the installation space of the controller 14 in the steam generator 13 is small. The point is that even if a plurality of input / output ports are provided, a pair of input / output ports can be formed.

Next, another embodiment of the control device for the ironing device according to the present invention will be described. In FIGS. 4 and 5, reference numeral 30 denotes a body provided with an input port 31 on the lower side and an output port 32 on the upper side, and a steam passage 33 that connects the input port 31 and the output port 32 is formed in the body 30.

A valve seat 34a having two steam passage areas, that is, a small steam passage and a large steam passage on the side of the steam passage 33,
34b and valve devices 35a and 35b, which are two electromagnetic valves for opening and closing the valve seats 34a and 34b, are hermetically attached. Further, the valve chambers 36a, 36 of the solenoid valves 35a, 35b are
In b, the passages 37a and 37b are extended substantially downward from the bottom to communicate with the input port 31.

The operation of this configuration will be described. When the valve seats 34a, 34b of the solenoid valves 35a, 35b are opened, steam is supplied to the iron body (not shown) through the steam passage 33 in the control device 39 by the internal pressure of the steam generator 38.

Next, when the opened valve seats 34a and 34b are closed, the steam in the steam passage from the valve seats 34a and 34b to the iron main body on the output port 32 side loses the pressure of the steam generator 38. Although it tries to stay, most of the kinetic energy up to that point is ejected from the iron body.

On the other hand, the steam in the steam passage 33 from the valve seats 34a, 34b to the steam generator 38 on the input port 31 side remains as it is, and if the ironing work is stopped and left as it is for a while, the inside of the valve chambers 36a, 36b is stopped. Condensate with. However, the moisture condensed in the valve chambers 36a, 36b is collected by its own weight at the bottoms of the valve chambers 36a, 36b, passes through the passages 37a, 37b extending substantially downward from the bottoms, the input port 31, and is returned to the steam generator 38. Be done.

Therefore, even if the ironing work is stopped and left for a while and the electromagnetic valves 35a and 35b are opened to eject the steam, a good quality steam having less water content, that is, less drainage can be obtained. ..

[0028]

As described above, in the ironing device of the present invention, the steam passage area changes when the combination of operating the plurality of valve devices is changed by the configuration of the control device, and the steam amount corresponding to each passage area is changed. Since the plurality of valve devices are integrally formed in the body having a pair of input / output ports, the valve devices are connected to each other, and the connection between each valve device and the steam generator, and Requires no new connecting member for connecting each valve device to the hose.

Therefore, the control device can be easily installed in the steam generator and the hose can be easily installed in the control device.

Further, since the passage is extended substantially downward from the bottom of the valve chamber of the valve device and communicates with the input port, the moisture that is condensed inside the valve chamber and adheres to the inner surface is collected by its own weight on the bottom of the valve chamber. To a steam generator through a passage extending generally downwardly from and an input port.

Accordingly, even if the steam passage is opened by the control device and the steam is jetted next, a good quality steam having less water content, that is, less drainage can be obtained, and a good finishing effect without stains on the fabric can be obtained. Is what you get.
