Description

  The present invention relates to a steam iron provided with a detachable attachment nozzle for ejecting steam, which increases the spray speed and pressure of steam.

  The steam iron opens a steam outlet at one location on the bottom of the bottom plate, heats the bottom plate with an electric heater provided on the bottom plate, and heats a predetermined amount of water injected into the iron. Thus, steam is generated and ejected through the steam outlet. And when ironing the fabric of the object to be stretched, the fabric of the object is spread on an ironing board, etc., and the bottom of the steam iron is pressed against this and slid while pressing, so that the fabric becomes hot. While moistening with steam, the heat of the bottom plate is blown away to stretch the straw.

  By the way, with such a steam iron stretcher, it is a work while pressing the fabric, so fine manual work is required to stretch the shirts around the shirt buttons, slack tacks, and pockets. Not only that, the ironing may cause the fabric to become shiny, and it is necessary to apply a drapery, which is troublesome and time consuming.

  For this reason, in recent years, steam irons have been developed and are beginning to spread using steam with a high energy amount, which can stretch the ridges by lightly pressing the iron without pressing it against the fabric and sliding it. The steam iron has a main body formed of a heat-resistant resin and a pair of electrodes on the inner surface side of the bottom plate. Is arranged.

  And when using the said steam iron, salt is mixed with the water accommodated in the case, and it melt | dissolves, and it heats by supplying with electricity through the said electrode to this salt water, and generate | occur | produces a steam | vapor with a high energy amount. It is like that. That is, by supplying steam having a high energy amount from the outlet into the recess of the bottom plate and penetrating the dough, the kneading can be performed with light pressure. In addition, thin fabric products such as Y-shirts and blouses can be stretched just by holding the steam iron in hand and applying high-energy steam blown from it, and the body is heat resistant. Since it is made of synthetic resin and lightweight, it can be stretched in a short time with a simple operation of simply spraying steam from the iron that is held on the hanger and the time just before going out. This is very useful when there is no room.

  However, in the case of the above-described conventional steam iron, in the case of a thin fabric material or its processed product that is easy to remove the cocoon by wetting, it was possible to stretch the cocoon by applying steam while hung on the hanger, If the fabric is thick, or if the target fabric is a material such as cotton, which is difficult to return the cocoon, or a processed product thereof, it is not possible to penetrate the interior of the fabric with sufficient steam to stretch the cocoon. For this reason, it has been necessary to repeatedly apply steam several times over the entire surface of the target fabric, which took time.

  The present invention solves the above problems, and its purpose is to increase the effect of penetration into the dough by increasing the speed and pressure of steam by attaching to a steam iron. It is to provide a steam iron with an attachment nozzle.

  In order to achieve the above object, the present invention provides a case for airtightly covering an upper portion of a bottom plate, heating means for generating water vapor by heating water contained in a sealed space inside the case, and water vapor in the sealed space. A taper-shaped steam blow-out hole that guides the gas to a steam blow-out opening formed on the bottom surface of the bottom plate, and an attachment nozzle that is detachably fitted in the steam blow-out hole. A tapered cylindrical portion that is detachably fitted into the blowing hole, a lid plate that is integrally formed at the tip of the cylindrical portion and closes the opening of the steam outlet, and is formed through the lid plate. And a plurality of vapor jetting pores.

  According to a second aspect of the present invention, in the first aspect of the present invention, the attachment nozzle removing tab is integrally projected and formed at least at one location on the outer peripheral portion of the lid of the attachment nozzle.

  Furthermore, the invention of claim 3 is the invention according to claim 1 or 2, wherein the lid plate of the attachment nozzle is formed in a curved shape bulging toward the outside, and the vapor ejection pores are normal to the curved surface. It is characterized in that it is formed so as to penetrate along the direction and arranged radially.

  Therefore, in the present invention, due to the nozzle effect of a plurality of pores, even when saturated steam of 100 ° C. or less, the steam blowing speed / pressure is increased, and the steam is sufficiently infiltrated into the target fabric, and the wetting effect Since the ironing operation is performed after increasing the height, the effect of stretching the heel is high, and it is also suitable for a fabric material having a temperature limit.

  In the invention of claim 2, since the tab can be removed as a lever when removing the attachment depending on the type of the fabric, the detaching operation is easy.

  In the invention of claim 3, it is possible to supply steam with high blast speed and pressure concentrated on the portion facing the attachment nozzle to the fabric to be stretched, and to make the vapor permeability to the fabric as possible as possible. Can be improved.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings. 1 and 2 show a steam iron to which the present invention is applied. The steam iron 1 includes a boat-shaped flat bottom plate 2 made of a heat-resistant synthetic resin molded body, and a sealed case 3 made of the same heat-resistant synthetic resin molded body fitted and fixed on the bottom plate 2 in a sealed state. I have.

  As for case 3, the front part 4 protrudes upwards, and the hollow part 5 is formed in the center part. An L-shaped handle portion 6 provided integrally with the rear portion of the case 3 projects forward and overhangs above the hollow portion 5. Further, as shown particularly in FIG. 2, a water inlet 4a is opened on the top surface of the front portion 4 of the case 3, and a watertight screw cap 7 is detachably attached to the water inlet 4a. A switch 8 is attached to the front end of the handle portion 6, and a power cord 9 connected to the switch 8 projects from the rear end.

  Further, as shown in FIG. 2, a sheet heater 10 connected to the power cord 9 via a switch 8 is inserted into the bottom plate 2 as a heating means by integral molding. The bottom surface of the bottom plate 2 is formed with a satin-like texture 2a, and ensures slipperiness with respect to the fabric in contact therewith. In addition, on the front side of the bottom surface of the bottom plate 2, a concave portion 2b having a predetermined area having a substantially hexagonal shape in which the front portion has a substantially isosceles triangle shape and the rear portion has a rectangular shape is formed. A steam outlet 2c is opened on the inner bottom surface of the section on the center line on the iron tip side.

  As shown particularly in FIG. 2, a blowing passage forming member 14 that defines a steam blowing hole 12 is integrally provided at the upper portion of the bottom plate 2 and protrudes into the case 3 at the steam blowing port 2 c. The blowing passage forming member 14 has a tapered cylindrical shape with its upper end closed, and a plurality of steam outlets 14 a for preventing priming are opened at the periphery of the upper end portion of the blowing passage forming member 14.

  The iron 1 includes a temperature sensor such as a bimetal (not shown). When the water in the interior becomes empty and the temperature further rises from the boiling temperature, the power can be automatically turned off. A switch that turns off the power even when 1 is laid down can be incorporated.

  Accordingly, in the iron 1 described above, the screw cap 8 is removed, a fixed amount of water is injected from the water injection port 4a through a measuring cup (not shown), and the screw cap 8 is attached to the water injection port 4a again to ensure water tightness. If the power cord 9 is connected to an outlet via a plug and the switch 8 is turned on, the heater 10 is heated. By heating the heater 10, the bottom plate 2 is heated, and at the same time, the temperature of the internal water rises, becomes saturated steam at the boiling point thereof, and blows out steam through the steam outlet 14 a and the steam outlet 12 of the outlet passage forming member 14. It blows out from the mouth 2c. In a state where the iron 1 is placed on the fabric, the iron 1 wraps around the recess 2b from directly below the steam outlet 2c, and saturated steam is supplied to the target fabric through these surfaces.

  By the way, since the above-mentioned steam injection speed and steam pressure correspond to the opening diameter R of the steam outlet 2c, the spray speed is rather moderate and is in a low pressure state. That is, the shape of the blowout port 2c and the blowout hole 12 is set so as to best suit the dough material due to moisture retention of the steam, so that the wrinkles are easily returned and the saturated steam temperature is about 100 ° C. . Therefore, it is difficult to say that there is sufficient vapor permeability for other fabric materials such as thick cotton.

  Therefore, in the present invention, as shown in FIGS. 3 and 4, an attachment nozzle 20 for ejecting steam to the opening of the outlet 2c is detachably attached. The attachment nozzle 20 is made of a heat-resistant resin molding similar to the bottom plate 2 and the case 3 of the iron 1, and can be attached to and removed from the inner periphery of the steam outlet 12, that is, the inner periphery of the outlet passage forming member 14. A tapered cylindrical portion 21 to be fitted, a lid plate 22 that is integrated at the tip of the cylindrical portion 21 and closes the opening surface of the steam outlet 2c, and penetrates the inside and outside of the lid plate 22 to form the steam. A plurality of pores 23 communicating with the inside of the outlet and a tab 24 for detachment operation integrally extending from a part of the outer side of the cover plate 22 are provided.

  The cylindrical portion 21 has the same taper shape as the inner surface taper shape of the blowing passage forming member 14, and the attachment nozzle 20 can be fixed and attached by taper fitting without requiring a fixing means. . Further, when the attachment nozzle 20 is removed, the attachment nozzle 20 can be easily removed by placing the finger on the tab 24 and prying it.

  The lid plate 22 is formed in a curved surface shape that slightly bulges toward the outside, and 5 in a radial manner in a total of five locations including the central portion of the curved surface and four locations spaced 90 ° from the periphery of the central portion. Two pores 23 are arranged, and the pores 23 are formed so as to penetrate along the normal direction of the curved surface. Each of these pores 23 has a reverse taper shape in which the inner surface side is increased in diameter and the diameter is decreased toward the outer surface side, and the nozzle effect is enhanced.

  A locking projection 25 is integrally formed on the outer peripheral edge of the cover plate 22 on the side opposite to the tab 24. The locking projection 25 protrudes in a columnar shape toward the back surface side of the lid plate 22 by an amount corresponding to the thickness of the lid plate 22, and is integrally formed by projecting by a semicircle also radially outward of the lid plate 22. ing. Then, when attaching the attachment nozzle 20 to the outlet 2c, the outer peripheral surface of the locking projection 25 is abutted and locked while rotating to the oblique side of the isosceles triangle portion in the front part of the recess 2b. Further, the tapered cylindrical portion 21 is pressed into the steam blowing hole 12 with a predetermined surface pressure to be fixedly locked. That is, when the attachment protrusion 20 is pushed in, the locking protrusion 25 has its tip abutted against the inner bottom surface of the recess 2b, and the flange portion of the outer peripheral portion of the lid plate 22 is spaced apart from the inner bottom surface of the recess 2b. This prevents the tapered cylindrical portion 21 from being taper-fitted to the steam blowing hole 12 by excessive surface pressure, and allows the tab 24 to be easily picked when removed due to its separation. The improvement of the nature is aimed at. Furthermore, the locking engagement of the attachment nozzle 20 is made more reliable by bringing the outer peripheral surface of the locking projection 25 into contact with the oblique side of the isosceles triangular portion in the front part of the recess 2b and press-fitting.

  In the steam iron with an attachment nozzle for steam ejection configured as described above, when the heater 10 is heated by inserting water W into the iron 1 as shown in FIG. Saturated steam is ejected radially through each pore 23 of the attachment nozzle 20 as shown by arrows in the horizontal use state of FIG. 5A and the vertical use state of FIG. Both the jet velocity and the pressure are much higher than when the attachment nozzle 20 is not provided (FIG. 2). Therefore, steam can be concentrated on the portion facing the attachment nozzle 20 with respect to the fabric, so that the vapor permeability to the fabric is improved as much as possible even at the same temperature.

  FIG. 6 shows an example in which the heater employed as the heating means in the above embodiment is replaced with an electrode. As shown in the figure, in this embodiment, a planar heater is not inserted in the bottom plate 2, and a pair of electrodes 30 are arranged on the inner surface side of the bottom plate 2 in place of the planar heater. It is fixed and attached at a predetermined interval in the width direction. The electrode 30 is supplied with AC commercial power from the power cord 9 via the switch 8, and the water in the case 3 is mixed and dissolved to form salt water. The heat generation is improved and the generation of steam is promoted. In addition, the amount of water measured by the measuring cup and injected into the case 3 is set to a maximum of half or less of the internal volume of the case 3, so that when the iron 1 is laid sideways, one of the pair of electrodes One is not soaked in salt water, and the current is cut off so that the generation of heat and steam is stopped.

  Although only one type of attachment nozzle 20 is disclosed in the illustrated example, it is possible to prepare a plurality of types of attachments with different hole diameters and numbers of holes and use them according to the target fabric material. Of course.
