First, the steam generator 10 of the present invention will be described with reference to FIGS. 1 to 5 as follows.

The steam generator 10 of the present invention is heated in a predetermined temperature range (temperature capable of generating steam) by the heating means 120, and water and waste steam (water and steam discharged through the drain pipe in a heated state). Steam is generated by receiving a steam generating medium composed of at least any one of the air and the steam generator 200 for heating the water supplied to the inner bottom surface of the housing 100 to convert to steam.

In the drawings, the housing 100 is illustrated as an upper housing (lid) and a lower housing, but may also be configured as a single housing 100, and the material is preferably made of aluminum in consideration of thermal conductivity and manufacturing cost.

In addition, although shown in the shape of a cylinder on the drawings, it is not preferable to limit the shape just as shown, and any structure having the steam generator 200 to be described later may be manufactured in various shapes.

Heating means 120 is to be connected to the inner lower portion of the housing 100, which is a known technique, so a detailed description thereof will be omitted.

The present invention uses at least one of water and waste steam and air as a steam generating medium.

Waste steam refers to the steam remaining after being used in the steam iron (hereinafter referred to as 'iron'), which is in the form of steam or water (steam is cooled and converted to water), and generally through a drain pipe connected to the steam iron. It is discharged to the outside.

The steam generator 200 may include a guide discharge part 230 formed between the first steam generator 210 and the second steam generator 220, and the first steam generator 210 and the second steam generator 220. It is configured to include).

Although the first steam generating unit 210 is illustrated as a multi-stage type of a disc, all of the first steam generating unit 210 may have a stepped shape in which the center upper portion is high and the height decreases toward the outer circumference portion. The multi-stage configuration, which gradually lowers from the center to the outer circumference, is to increase the contact area and the contact time when the steam generating medium is supplied.

As shown in FIGS. 3 and 4, the second steam generator 220 is formed along the circumferential end of the lower portion of the outer periphery of the guide discharge unit 230, and the second steam generator 220 is also increased and decreased. It consists of repeating staircases.

That is, the auxiliary steam forming means 221 is formed in a stepped shape so that the height is gradually lowered from the upper portion of one point (in the middle of each of the auxiliary steam forming means 221 in the case of FIG. At least a plurality of pieces are formed along the circumference of the 230.

Referring to Figure 3, the auxiliary steam forming means 221 is composed of four, each connection portion of the auxiliary steam forming means 221 is formed at the lowest position (east, south, west, north and south directions) in the second steam generating unit 220, A discharge hole 130 is formed in the portion.

Referring to FIG. 4, the discharge holes 130 are formed to be inclined downward from the inner circumference of the housing 100 toward the center of the housing 100, and each discharge hole 130 is disposed at the lower center of the housing 100. It is connected to the drain pipe 140 formed. Through the discharge hole 130, foreign substances, waste steam, and water in the housing 100 may be discharged to the outside (possibly for washing).

The present invention supplies a steam generating medium in the upper center of the housing 100, that is, the center vertical upper portion of the first steam generating unit (210). Thus, referring to Figure 5, the inlet discharge hole 110 is located in the upper portion of the vertical direction above the center of the first steam generating unit 210, the third transfer pipe (only one transfer pipe for supplying the steam generating medium ( 600 passes through the transfer hole 310 of the inlet discharge pipe 300 coupled with the inlet discharge hole 110 and is connected to a position spaced apart from the upper portion in the vertical direction above the center of the first steam generator 210 by a predetermined interval. As shown, the outer diameter of the third transfer pipe 600 is formed smaller than the diameter of the transfer hole (310).

Since the steam generating medium is transferred through a single pipe, when water, waste steam, and air are simultaneously transferred, the amount of water is controlled to supply the optimum amount to the steam generator.

The inlet discharge pipe 300 is coupled to communicate with the inside of the housing 100 in the inlet discharge hole 110 formed in the housing 100, as shown in Figure 5, the transfer hole 310 is formed in the vertical direction up and down In communication with the transfer hole 310 in the lateral direction of the transfer hole 310 to discharge (supply) the steam generated in the steam generator 200 and introduced into the transfer hole 310 toward the steam supply pipe 800. The steam discharge hole 320 is formed.

Therefore, the steam generating medium passes through the transfer hole 310 of the inlet discharge pipe 300 coupled to the inlet discharge hole 110 provided in the housing 100 as a third transfer pipe 600 which is one transfer pipe. The steam generator 210 is supplied to the steam generator 200 and is converted into steam through the steam generator 200, and then the steam is introduced into the transfer hole 310 of the inlet and outlet pipe 300 coupled to the inlet and outlet hole 110. , The steam introduced into the transfer hole 310 has a structure that is discharged (supplied) to the steam supply pipe 800 side through the steam discharge hole 320 provided in the inlet discharge pipe 300, but not shown, steam discharge hole (320) Between the transfer hole 310 and the third transfer pipe 600 provided in the inlet discharge pipe 300 of the upper may be configured in a closed structure.

This has a very important meaning, when supplying the steam generating medium through the eccentric place instead of the center can not use the entire heating plate, such as the steam generating unit 200, the problem is solved through the structure supplied from the upper center It was.

In addition, by forming a structure that is discharged again through the center of the upper portion of the steam generated in addition to the structure to supply from the upper portion, the transfer path of water supplied from the steam generating medium supply hole to the steam discharge hole 320 is generally formed Is to prevent that. In other words, if steam is discharged from one of the eccentric positions instead of the center, even if water is supplied from the center to maximize the water heating area, the water flows in only one direction due to the pressure from which steam is discharged. Since only one portion of the heating efficiency is reduced, the present invention is a structure that solves this.

Meanwhile, the guide discharge part 230 is formed between the first steam generator 210 and the second steam generator 220.

Guide discharge portion 230 is formed in the upper direction around the end side of the first steam generating portion 210, the constant size of the water droplets moved from the center of the first steam generating portion 210 to the outer end (circumferential portion) Only the following water droplets are guided to be discharged to the second steam generator 220.

That is, referring to FIG. 3, protrusions are formed at a predetermined interval, and a portion in which the discharge hole 130 is located is wider than protrusions of other portions, and other portions have protrusions of the same size at regular intervals. Since it is formed, only water droplets having a diameter or less corresponding to the interval between the protrusions are discharged to the second steam generator 220.

The water droplets discharged to the second steam generating unit 220 are heated once again in the auxiliary steam forming unit 221 and converted into steam, and the converted steam flows in the upper vertical center of the first steam generating unit 210. It is discharged to the outside through the transfer hole 310 of the discharge pipe (300).

In addition, according to the present invention, by supplying air (air) together, the steam pressure inside the steam generator is rapidly increased, generating a high temperature dry steam with less moisture, and supplying the optimum dry steam when using the iron while reducing condensate and waste water. Can be.

First, an embodiment of the steam generation structure of the steam iron according to the present invention will be described with reference to FIG. 6.

The steam generator 10 has an inlet discharge pipe 300 having a transport hole 310 formed in the vertical direction in the vertical direction and having a steam discharge hole 320 communicating with the transport hole 310 on the side thereof, and transported to the inlet discharge hole 110. Since the lower part of the hole 310 is coupled to communicate with each other, the detailed configuration of the steam generator 10 is described in detail above, and thus description thereof will be omitted.

The first transfer pipe 400 is connected to the first transfer pump 410 as a tube for transferring water.

The second transfer pipe 500 is a pipe for transferring air, and a second transfer pump 510 such as an air compressor is connected.

Although only the form in which water and air are transported in the drawings, only the waste steam and air may be transported.

The third transfer pipe 600 is to transfer the steam generating medium (water and air) introduced through the first transfer pipe 400 and the second transfer pipe 500 to a single pipe, the first check valve ( 610 is provided is connected to the steam generator 10 through the transfer hole 310 of the inlet and outlet pipe (300). Therefore, the third transfer pipe 600 is not limited to the bar as shown to refer to a pipe that is mixed with water and air or waste steam and air is transferred to a single pipe. Steam generated by the configuration of the first check valve 610 is supplied only to the iron 900 through the steam supply pipe (800).

Steam ball feed medium supplied through the third transfer pipe 600 is converted into steam in the housing 100, the converted steam is steam supply pipe 800 connected between the steam discharge hole 320 and the steam iron (900) It is discharged to the steam iron 900 through. Accordingly, the steam iron 900 is to receive the steam through the steam supply pipe (800).

Next, another embodiment of the steam iron using the steam generator of the present invention will be described with reference to FIG. 7.

Another embodiment is a structure for supplying water, waste steam, and air to the steam generator 10 as a steam supply medium, which is an optimal embodiment.

Since the structure of the steam generator 10, the first transfer pipe 400, the second transfer pipe 500 and the steam supply pipe 800 is the same as the embodiment, it can be referred to the above description.

In another embodiment, the fourth transfer pipe is connected to the drain pipe of the steam iron 900 so that the waste steam is transferred to the first transfer pipe 400 side, and has a second check valve 710 as a check valve. 700 is further provided. The configuration of the second non-return valve 710 may prevent the waste steam from flowing back to the drain pipe of the iron 900.

On the other hand, the waste steam and water is mixed and supplied to the third transfer pipe 600 by the third transfer pump 620, mixed with the air supplied through the second transfer pipe 500 is finally one transfer pipe It is supplied into the housing 100 of the steam generator 10 through the third transfer pipe (600).

Since there is pressure in the waste steam itself, there is no need for a separate transfer pump such as the third transfer pump 620. However, since the waste steam cools down and the supply may not be performed smoothly, the waste steam has a third transfer pump 620 to transfer. It is preferable.

By the above structure, the waste steam can be recycled, and the heat remaining in the waste steam can be recycled, thereby reducing power consumption and water consumption.
