Iron and double-pipe nipple assembly for iron

The present invention relates to a double tube hose nipple assembly for an iron and an iron, and more specifically, to eliminate the inconvenience of having to install a steam supply hose and a drain water discharge hose with one double steam hose and steam to the outside air. The present invention relates to an iron and iron double hose hose nipple assembly for maintaining the steam temperature properly by changing the flow path of steam so as to prevent the temperature from being lost.

Iron is a tool used to stretch and wrinkle clothing by using heat, pressure, and moderate moisture in the fabric. Such irons have a bactericidal effect because of their high temperature, and are also used when the fibers need to be preserved for a long time because they also kill eggs of mold or pests.

Types include charcoal irons, gas irons, electric irons, steam irons, and steam irons. Previously, many charcoal irons were used, which consisted of cast iron in the shape of a concave bowl of 20 cm in diameter, with a smooth bottom and long wooden handles. These charcoal irons disappeared in the roots of electric irons as conventional irons.

At home, electric irons are usually used for convenience and safety. And, where a large amount of laundry is managed and processed, such as a laundry, usually use a steam iron or a combined electric iron.

On the other hand, a common iron that we commonly say is imagine a small electric iron that can be commonly encountered at home, but in the following, it is used in a laundry or the like, and various hoses or steam devices connected to it, including the iron body, are used. All of them will be described as irons.

As will be described in detail below, in order to iron by using a conventional steam iron or steam combined electric iron (hereinafter, these are referred to as "irons"), an iron or steam as well as a structure for supplying a certain amount of steam to the iron body There is a need for a structure for discharging naturally occurring drain water in the hose.

Thus, according to the related art, a steam supply hose for supplying steam and a drain water discharge hose for discharging drain water have been installed on the iron, respectively.

However, when the steam supply hose and the drain water discharge hose are separately provided as described above, the arrangement relationship with the iron is quite inconvenient, and the ironing work is also troublesome.

Thus, in the prior art, including the Republic of Korea Patent Application No. 96-28302, in order to solve this problem, after forming the steam supply hose and the drain water discharge hose integrally with a double tube type hose, the double pipe hose for iron at a certain point The nipple assembly 130 is mounted, and the nipple assembly 130 diverges steam and drain water in an appropriate direction.

A conventional double tube hose nipple assembly for irons will be described with reference to FIGS. 4A and 4B.

First, as shown in FIG. 4A, the conventional double tube hose nipple assembly 130 for the iron includes a nipple main body 132 and a nipple main body 132 having two branch passages (not shown) formed therein. Consists of a steam pipe connector 137 is coupled to one side, and a drain water pipe connector 139 is coupled to the other side.

The nipple body 132 is composed of a body portion 133 having a non-circular cross section according to its position, and a screw portion 134 for screwing the body portion 133 into a separate pipe. When the front surface of the nipple body 132 is viewed, as illustrated in FIG. 4B, a drain hole 135a through which drain water moves is formed in a central portion thereof, and steam is formed on the radially outer side of the drain hole 135a. It can be seen that the moving steam hole 134a is formed.

Thus, the steam generated in the boiler is introduced into the iron body (not shown) along the steam hose 120 via the steam pipe 141 through the steam pipe connector 137 and the steam hole 134a. Therefore, the worker uses the steam flowing into the iron body to straighten and wrinkle the garment.

While the ironing is performed or while the ironing work is being rested for a while, the bottom or steam hose inside the iron main body due to the temperature difference between the inside of the steam hose 120 and the outside air or the temperature difference between the temperature in the iron main body and the outside air. Drain water is generated inside 120. If the drain water is naturally vaporized in the chamber in the iron body, this is not a problem, but if it continues to accumulate without vaporizing, the performance of the iron is inevitably deteriorated.

Thus, the drain water accumulated in the iron body is properly discharged (drained), first moves along the steam hose 120 to reach the nipple assembly 130. Of course, since the steam hose 120 is a double pipe, the flow path through which the steam moves and the flow path through which the drain water moves cannot be combined together.

The drain water reaching the nipple assembly 130 is first drained through the drain hole 135a and drained along the drain water pipe 142 via the drain water pipe connector 139.

By the way, the conventional iron pipe hose nipple assembly 130 for the iron, it can be seen that the steam hole 134a to which the steam moves is disposed in the radially outer side of the drain hole 135a. Therefore, there is a problem that it is difficult to match the desired steam temperature because the steam is taken away from the outside air in the process of supplying steam from the boiler.

In addition, there is a disadvantage in that the drain water 135a (hereinafter, the configuration corresponding thereto is a drain water flow passage 35a) having a relatively fine diameter is easily caught and foreign water is not easily discharged. .

Therefore, the object of the present invention is to eliminate the inconvenience of having to install the steam supply hose and drain water discharge hose with one dual steam hose, and to prevent steam from being deprived of its temperature by the outside air. It is to provide a double tube hose nipple assembly for irons and irons that can maintain the proper steam temperature while saving energy by changing the flow path.

In addition, another object of the present invention is to provide a double tube hose nipple assembly for irons and irons capable of finely discharging drain water while preventing foreign matter from easily trapping in the drain water flow passage.

The steam pipe connector is equipped with a steam pipe for delivering steam; One end of the steam flow passage part is disposed at the connection part for the steam pipe, and the other end passes through the body part of the nipple body and extends to the outside of the body part to connect steam from the steam pipe to the steam pipe connection part, the steam flow path part. And transfers to the iron body through the steam hose.

On the other hand, the above object is also achieved by an iron for arranging the double tube hose nipple assembly for ironing according to any one of claims 1 to 3 to branch the steam and the drain water in some section.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, and in the description of each embodiment, the same reference numerals will be given to the same components.

1 is an overall configuration diagram of an iron double tube hose nipple assembly according to a first embodiment of the present invention, Figure 2a is an enlarged view of the iron double hose hose nipple assembly, Figure 2b is a front view of Figure 2a. .

As shown in FIG. 1, the iron according to the first embodiment of the present invention consists of an iron body 10, a double steam hose 20, a steam pipe 41, and a nipple assembly 30.

Of course, in FIG. 1, a separate drain water pipe 42 is further illustrated, and a drain nipple 46 is shown in the drain water pipe 42, and the nipple assembly 30 is formed by the drain hose 48. It can be seen that the drain nipple 46 is connected.

However, since the drain hose 48 may be directly connected to the drain water pipe 42, the drain nipple 46 is not necessarily configured. However, if configured as shown in Figure 1 has the advantage that can be set more safely and effectively iron.

Iron body 10 as a main part for unfolding and pleating the clothes, as shown in Figure 1, the body portion 12, and the steam control valve 13 provided on the upper portion of the body portion 12 and , The valve lever 14 for operating the steam control valve 13, and the handle portion 16 for holding the iron body (10). Of course, the shape, size and shape of the iron body 10 may be sufficiently changed depending on the article.

In the body portion 12, first and second chambers 12a and 12b partitioned in the vertical direction are formed. In addition, the valve pin 15 is mounted in a space in which the steam control valve 13 and the first and second chambers 12a and 12b communicate with each other. One side of the body portion 12 is formed with a connector 21 for coupling the dual steam hose 20 to the iron body (10).

Looking at the inside of the iron body 10 adjacent to the connector 21, the steam discharge portion 20a extending from the double steam hose 20 to transfer steam and the drain water generated in the iron body 10 are sucked in. A drain water suction part 20b is formed.

The dual steam hose 20, which serves to deliver steam or discharge drain water, is formed of a double tubular body and has a Teflon material, which can be flexibly bent as previously applied by the present applicant.

Since the dual steam hose 20 has a double pipe inside thereof, the flow path through which steam actually moves and the flow path through which the drain water moves are different. That is, the steam is the central region of the double steam hose 20. To the outside of the drain water. Therefore, the steam and the drain water cannot be combined together in the double steam hose 20.

On the other hand, as shown in Figures 2a and 2b, the dual tube hose nipple assembly 30 for the iron according to the present invention, the radial direction of the steam flow passage 34a and the steam flow passage 34a forming the flow path of steam The nipple body 32 having a drain water flow channel hole 35a formed on the outside, the connection portion 37 for the steam pipe which is connected to one side of the nipple body 32 and communicates with the steam flow path portion 34, and the nipple body It is coupled to the other side of 32 has a drain water pipe connector (39) in communication with the drain water passage (35).

The nipple main body 32 has a non-circular cross-section body portion 33 and a tubular steam flow passage portion extending outward from the center inside of the body portion 33 to form a steam flow passage 34a ( 34 and a tubular shape arranged to surround the steam flow passage 34 on the radially outer side of the steam flow passage 34 to form an annular drain flow passage 35a between the steam flow passage 34 and the steam flow passage 34. The drain water flow path part 35 is provided.

The steam pipe connector 37 is equipped with a steam pipe 41 for transmitting steam, between which the steam switch 45 is additionally mounted. In addition, the drain 39 is connected to the drain nipple 46 and the drain water switch 47, and the drain water switch 47 is connected to the drain water pipe 42. ) Is integrally coupled to. Of course, the steam switch 45 and the drain water switch 47 as described herein is for selectively blocking the line, it is not necessarily a configuration to be provided.

One end of the steam flow path part 34 is disposed at the connection part 37 for the steam pipe, and the other end passes through the body part 33 of the nipple body 32 and extends to the outside of the body part 33. . Thus, the steam generated in the boiler, flows through the steam pipe 41, and after reaching the steam pipe connector 37, the double steam hose (20) through the steam flow path 34a of the steam flow path 34 Flows into). Then, it is discharged into the iron body 10 through the steam discharge portion 20a formed at the end of the double steam hose (20).

At this time, the flow path of the steam is formed in the center region of the nipple body 32 as described above can overcome the disadvantage that the steam is in contact with the outside air and the temperature is taken away. Therefore, there is an advantage that can always maintain the temperature of the steam properly.

On the other hand, the drain water flow path part 35 disposed outside the steam flow path part 34 is molded integrally by the body part 33 and a single material for the convenience of molding. I am doing it. Of course, in some cases, these may be manufactured separately and then forcedly bonded by welding or soldering.

The drain water flow passage 35a formed between the steam flow passage portion 34 by the drain water flow passage portion 35 communicates with the inside of the nipple body except for the thickness of the steam flow passage portion 34, and thereafter, for drain water piping. Communicates with the connector 39.

As a result, the drain water naturally generated in the iron body 10 is transferred to the double steam hose 20 through the drain water suction part 20b, and then flows into the nipple body through the drain water flow passage 35a. Then, it is discharged to the drain water pipe 42 via the drain water pipe connector 39, the drain hose 48, the drain nipple 46 and the drain water switch 47.

At this time, since the drain water flow path hole 35a of the present invention is formed in a ring shape between the steam flow path part 34 and the drain water flow path part 35, foreign substances are trapped in this area unlike in the prior art to discharge the drain water. It will be able to properly resolve this blockage.

By this structure, the steam generated in the boiler (not shown) passes through the steam pipe 41 and the steam switch 45 to reach the connection pipe 37 for steam pipe. After such a stream flows into the dual steam hose 20 through the steam flow passage 34a of the steam flow passage 34, and then through the steam discharge unit 20a formed at the end of the dual steam hose 20 iron body ( 10) It is released inside. Thus, the worker uses the steam flowing into the iron body 10 to stretch and wrinkle the garment.

While the ironing is performed, drain water is generated on the bottom surface of the iron main body 10 due to the temperature difference between the inside of the double steam hose 20 and the outside air, or the temperature difference between the temperature in the iron main body 10 and the outside air. do. If the drain water generated in this way is naturally vaporized in any one of the chambers 12a and 12b in the iron body 10, this is not a problem, but if it continues to accumulate without vaporizing, the performance of the iron may be deteriorated.

Accordingly, the drain water accumulated in the iron body 10 is appropriately discharged (drained). First, the drain water flow passage 35a is moved to the double steam hose 20 through the drain water suction part 20b. Through the nipple is introduced into the body. Then, the water is discharged to the drain water pipe 42 through the drain water pipe connector 39, the drain hose 48, the drain nipple 46, and the drain water switch 47.

As described above, according to the present invention, not only can the steam temperature be properly maintained by changing the moving flow path of the steam so as to prevent the steam from being taken away by the outside air, but also the foreign matter in the drain water flow channel hole 35a It can prevent the fitting easily and drain the drain water smoothly.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

In the above embodiment, the steam iron is illustrated and described. However, as shown in FIG. 3, the idea of the present invention can be sufficiently applied even in the case of a combined electric iron.

However, in the case of the steam combined electric iron of FIG. 3, the drain water is more likely to exist in the double steam hose 20 than in the iron main body 10. Therefore, since a structure for discharging the drain water existing in the double steam hose 20 is required, the steam discharge unit 20a and the drain water suction unit 20b are removed unlike in FIG. 1. However, even if the drain water present in the double steam hose 20, the above method can be used as it is, it is possible to use for a long time without failure while maintaining the performance of the iron to the maximum.

As described above, according to the present invention, it is possible to solve the inconvenience of having to install the steam supply hose and the drain water discharge hose with one double steam hose and to prevent the steam from being deprived of its temperature by the outside air. By changing the moving flow path of, there is an effect of maintaining the steam temperature properly while saving energy.

In addition, according to the present invention, it is possible to finely discharge the drain water while preventing the foreign matter easily caught in the drain water flow passage.
