It is done. Thereby, when the base 11 is lower than the vaporization temperature of the liquid, the bimetal is in a return state and both the auto valves 57 and 58 are closed. On the other hand, when the base 11 becomes equal to or higher than the vaporization temperature of the liquid, In an inverted state, both the auto valves 57 and 58 are opened, and the water that has passed through the concentration side auto valve 57 is dropped through the concentration side water passage 54 into the dripping receiver 35 of the concentration side vaporization chamber 32 and dispersed. The water that has passed through the side auto valve 58 passes through the dispersion side water passage 55 and is dropped onto the dripping receiver 38 of the concentrated side vaporization chamber 33.

  Next, the internal structure of the tank assembly 17 will be described with reference to FIGS. 8 to 12. Reference numeral 61 denotes a valve device that is linked to the steam / dry switching lever 21A, and 62 is a pump device that is linked to the shot button 21B. 62 is a mist spraying device interlocked with the mist button 21C. A jet port 64 of the mist jet device 63 is disposed below the water injection lid 18, and water in the tank assembly 17 is jetted from the jet port 64 as a mist-like mist every time the mist button 21 </ b> C is pushed. . Further, inside the tank assembly 17, there are a water storage chamber 65 for storing water from the water inlet lid 18, and an operation unit 21 except for the temperature setting / off button 21D and a mechanism movable chamber 66 for housing its movable mechanism. A partition wall 67 is provided that divides up and down.

  The pump device 62 is provided inside the tank assembly 17 as a liquid supply device that temporarily sends a large amount of water to the concentration side vaporization chamber 32 or the dispersion side vaporization chamber 33 in conjunction with the pressing operation of the shot button 21B. It is done. The pump device 62 includes a cylindrical cylinder member 70 that is rotatably accommodated and held in a concave cylinder holding portion 69 formed in the partition wall 67, and the inside of the cylinder member 70 is slid vertically in a watertight state. A piston 71 that is movably provided, and an elastic body 72 such as a spring that urges the piston 71 that contacts the lower part of the shot button 21 upward so that the shot button 21B always protrudes from the tank assembly 17. I have. In the present embodiment, in order to reduce the number of parts, a part of the cylinder member 70 is configured as a concentration / dispersion switching lever 21E, and the concentration / dispersion switching lever 21E formed to protrude from the outer surface of the cylinder member 70. However, the tank assembly 17 is rotatably exposed from one side surface of the tank assembly 17. As described above, in the present embodiment, a double cylinder structure in which the cylinder member 70 rotates with respect to the cylinder holding portion 69 by the switching operation of the concentration / dispersion switching lever 21E is incorporated in the tank assembly 17. .

  As shown in FIG. 10, one water supply hole 74, two concentrated side water discharge holes 75, and a dispersion side water discharge hole 76 are formed at predetermined intervals on the bottom surface of the cylinder holding portion 69. The water supply hole 74 communicates with the water storage chamber 65 inside the tank assembly 17. The concentrated side discharge hole 75 communicates with a concentrated side discharge port 78 exposed on the bottom surface side of the tank assembly 17 through a concentrated side discharge path 77 provided inside the tank assembly 17. The dispersion side discharge passage 79 provided in the tank assembly 17 communicates with the dispersion side discharge port 80 exposed on the bottom surface side of the tank assembly 17. When the tank assembly 17 is mounted on the main body 1, the concentration side discharge port 78 and the concentration side auto valve 57 communicate with each other in a watertight state, and the dispersion side discharge port 80 and the dispersion side auto valve 58 are similarly watertight. It becomes the composition which communicates with.

  As shown in FIGS. 11 and 12, the bottom surface of the cylinder member 70 has one curve that allows the inside of the cylinder member 70 to communicate with the water supply hole 74 regardless of the operation position of the concentration / dispersion switching lever 21E. A long hole 81 and a concentration guide hole 82 that enables communication between the inside of the cylinder member 70 and the concentration side discharge hole 75 when the concentration / dispersion switching lever 21E is switched to the “concentration” side that is the first position. When the concentration / dispersion switching lever 21E is switched to the “dispersion” side that is the second position, the dispersion guide holes 83 that allow the inside of the cylinder member 70 and the dispersion-side discharge holes 76 to communicate with each other are formed as openings. Is done.

  FIG. 11 shows the state inside the tank assembly 17 when the concentration / dispersion switching lever 21E is positioned on the “concentration” side. In this case, the inside of the cylinder member 70 is passed through the curved long hole 81. And the water supply hole 74 communicate with each other, the hole positions of the concentration guide hole 82 and the concentration side discharge hole 75 coincide with each other, and the inside of the cylinder member 70 and the concentration side discharge hole 75 communicate with each other. FIG. 12 shows the internal state of the tank assembly 17 when the concentration / dispersion switching lever 21E is positioned on the “dispersion” side. In this case, the cylinder member 70 of the cylinder member 70 passes through the curved long hole 81. The interior and the water supply hole 74 communicate with each other, the hole positions of the dispersion guide hole 83 and the dispersion side discharge hole 76 coincide with each other, and the inside of the cylinder member 70 and the dispersion side discharge hole 76 communicate with each other.

  The concentrated discharge port 78 and the concentrated discharge port 80 provided with the valve body constitute a part of the valve device 61, and when the steam / dry switching lever 21A is switched to the “dry” side, When the tank assembly 17 is removed from the main body 1, the valve bodies of the concentration side discharge port 78 and the dispersion side discharge port 80 are closed in order to prevent water discharge from the tank assembly 17 to the outside. On the other hand, when the steam / dry switching lever 21A is switched to the “steam” side while the tank assembly 17 is correctly attached to the main body 1, the valve bodies of the concentration side discharge port 78 and the dispersion side discharge port 80 are both opened. Water stored in the water storage chamber 65 is led from the concentration side discharge port 78 and the dispersion side discharge port 80 to the concentration side auto valve 57 and the dispersion side auto valve 58 through the valve device 61. Further, when the shot button 21B is pushed against the elastic body 72, the water fed into the cylinder member 70 from the water storage chamber 65 positions the concentration / dispersion switching lever 21E on the “concentration” side. In this case, when the concentration / dispersion switching lever 21E is positioned on the "dispersion" side through the concentration side discharge hole 75, the concentration side discharge port 78 leads to the concentration side auto valve 57. The discharge port 80 leads to the dispersion-side auto valve 58.

  Next, the effect | action regarding a steam function is demonstrated especially about the iron of the said structure. The water injection lid 18 is opened and closed, a predetermined amount of water is accommodated in the tank assembly 17, and the tank assembly 17 is set in front of the iron body 1. Subsequently, while the iron body 1 is placed on the placing table 2 and the power supply voltage from the cord 3 is supplied to the iron body 1, the temperature setting / off button 21D is pushed and operated. Set the temperature according to the fabric to be used. As a result, in the iron body 1, the heater 31 is controlled so that the temperature of the base 11 detected by the temperature detecting means approaches the temperature set by the temperature setting / off button 21D, and concentrated side vaporization is performed. The base 11 including the chamber 32 and the dispersion side vaporization chamber 33 is heated.

  Further, when the user uses the steam function, when the steam / dry switching lever 21A is switched to the “steam” side, the valve bodies of the discharge ports 78 and 80 constituting the valve device 61 open in conjunction therewith, Water can flow from the inside of the tank assembly 17 to the water passages 54 and 55 through the auto valves 57 and 58. When the steam / dry switching lever 21A is switched to the “dry” side, the valve bodies of the discharge ports 78 and 80 are closed, and the flow of water from the tank assembly 17 to the water passages 54 and 55 is interrupted. In this case, the iron body 1 can be used as a dry iron in which steam is not ejected from the steam concentrated ejection holes 43 or the steam dispersion ejection holes 44.

  Immediately after the heating of the base 11 by the heater 31 is started, the base 11 does not reach the vaporization temperature of water, the bimetal attached to the base 11 is in a return state, and both the auto valves 57 and 58 are closed. . Therefore, in this case, even when the steam / dry switching lever 21A is switched to the “steam” side, the flow of water from the tank assembly 17 is blocked by the auto valves 57 and 58, and the steam concentrating jet hole from that point onward. It is possible to prevent the water droplets that are not vaporized from being ejected at the time of ironing or the like by the nozzles 43 and the steam dispersed ejection holes 44.

  Thereafter, when the base 11 is sufficiently heated and rises above the vaporization temperature of water, the bimetal that has been in the restored state is transformed into an inverted state, and the auto valves 57 and 58 are both opened. Therefore, in this case, with the steam / dry switching lever 21A switched to the “steam” side, the water inside the tank assembly 17 is guided to the water passages 54, 55 through the auto valves 57, 58, and the concentration side vaporization chamber 32 is supplied. Alternatively, the steam generated in the dispersion side vaporization chamber 33 can be ejected from the corresponding steam concentration ejection holes 43 and the steam dispersion ejection holes 44.

  During such normal steam operation, in order to perform so-called shot ejection that temporarily increases the amount of steam ejection, the shot button 21B protruding above the tank assembly 17 is pushed. At this time, depending on the position of the concentration / dispersion switching lever 21E operated by the user, the steam ejection can be switched between “concentration” and “dispersion”.

  Specifically, when the concentration / dispersion switching lever 21E protruding to one side of the tank assembly 17 is moved to the “concentration” side position shown in FIG. The hole 74 communicates, and the inside of the cylinder member 70 and the concentrated side discharge hole 75 communicate with each other through the concentrated guide hole 82, while the dispersion side discharge hole 76 is blocked by the bottom surface portion of the cylinder member 70. Therefore, when the piston 71 is pushed up together with the concentration / dispersion switching lever 21 </ b> E by the repulsive force of the elastic body 72, the water stored in the water storage chamber 65 inside the tank assembly 17 passes through the water supply hole 74 and the cylinder member 70. When the piston 71 is pushed together with the concentration / dispersion switching lever 21 </ b> E against the repulsive force of the elastic body 72, the water sucked into the cylinder member 70 is collected into the concentration side discharge hole 75. From the concentrated side auto valve 57 on the upper surface side of the base 11 to the concentrated side water passage 54.

  Therefore, when the concentration / dispersion switching lever 21E is positioned on the “concentration” side, only the water guided to the concentration side water passage 54 temporarily increases and drops into the dropping receiving portion 35 of the concentration side vaporization chamber 32. The steam vaporized in the concentration side vaporization chamber 32 is guided from the concentration side steam space 36 to the steam concentration injection hole 43 and concentrated on the cloth or the like from the steam concentration injection hole 43 provided in one area of the hanging surface 41. Steam can then be ejected.

  Although not shown, the water supply passage from the water storage chamber 65 to the water supply hole 74 is provided with a first ball valve, and the concentration side discharge passage 77 from the concentration side discharge hole 75 to the concentration side discharge port 78 includes Another second ball valve is provided. These ball valves move according to the internal pressure of the cylinder member 70. When water is sucked into the cylinder member 70, the water supply passage is opened and the concentration side discharge passage 77 is closed, while the inside of the cylinder member 70 is closed. When water is discharged from the water, the water supply passage is closed and the concentrated discharge passage 77 is opened.

  On the other hand, when the concentration / dispersion switching lever 21E is moved to the “dispersion” side position shown in FIG. 12, the inside of the cylinder member 70 and the water supply hole 74 communicate with each other through the curved long hole 81, and the cylinder member 70 of the cylinder member 70 passes through the dispersion guide hole 83. The inner side and the dispersion side discharge hole 76 communicate with each other, whereas the concentrated side discharge hole 75 is closed by the bottom surface portion of the cylinder member 70. Therefore, when the piston 71 is pushed up together with the concentration / dispersion switching lever 21 </ b> E by the repulsive force of the elastic body 72, the water stored in the water storage chamber 65 inside the tank assembly 17 passes through the water supply hole 74 and the cylinder member 70. When the piston 71 is pushed and operated together with the concentration / dispersion switching lever 21E against the repulsive force of the elastic body 72, the water sucked into the cylinder member 70 is dispersed into the dispersion side discharge hole 76. From the dispersion side auto valve 58 to the dispersion side water passage 55 on the upper surface side of the base 11.

  Therefore, when the concentration / dispersion switching lever 21E is positioned on the “dispersion” side, only the water guided to the dispersion-side water passage 55 temporarily increases and drops on the dropping receiving portion 38 of the dispersion-side vaporizing chamber 33. The steam vaporized in the dispersion side vaporization chamber 33 is guided from the dispersion side vapor space 39 to the steam dispersion ejection holes 44, and from the steam dispersion ejection holes 44 provided in a wide area of the hanging surface 41 and the inclined surface 46, Steam can be spouted dispersed in cloth.

  Also in this case, a third ball valve that is movable in accordance with the internal pressure of the cylinder member 70 is provided in the dispersion side discharge passage 79 from the dispersion side discharge hole 76 to the dispersion side discharge port 80, and is provided inside the cylinder member 70. When water is sucked in, the water supply path from the water storage chamber 65 to the water supply hole 74 is opened and the dispersion side discharge path 79 is closed, while when water is discharged from the inside of the cylinder member 70, the water supply path is closed and the dispersion side discharge is performed. The path 79 is opened.

  In the present embodiment, there is an advantage that the shot ejection can be switched between “concentrated” and “dispersed” in accordance with the use application of the iron. For example, the above-mentioned “concentration” side shot (increase steam) jetting is optimal for wrinkle stretching of clothes hung on a hanger, stubborn wrinkle stretching of clothes, and substitution of a mist function. On the other hand, the shot dispersion on the “dispersion” side is most suitable for wrinkling of clothes in the state of ironing, and for wrinkling of fibers such as chemical fibers that are difficult to wrinkle.

  In general, clothing that is hung on a hanger cannot be pressed to press the hanging surface 41 against the clothing, so that the wrinkle is difficult to stretch, and the steam pressure is reduced by that amount if the steam is blown from the entire conventional hanging surface, Can't stretch wrinkles firmly. However, in the “concentrated” side shot ejection as in the present embodiment, the steam pressure is increased and the steam is ejected from the steam concentrated ejection holes 43 that are concentrated on one area of the hanging surface 41. It is possible to perform the wrinkle stretching well. In addition, in the “dispersion” side shot ejection, it becomes possible to give moisture to the fabric over a wide range.

  FIG. 13 shows a wrinkle level comparison chart stipulated in JIS C 9804 “Performance Measuring Method for Home Electric Iron”. FIG. 14 shows the evaluation result of the test regarding the relationship between the steam pressure and the wrinkle elongation due to the shot ejection. The wrinkle level number on the vertical axis in the figure corresponds to the number on the wrinkle level comparison chart shown in FIG. doing. In this test, when a weight of 500 g is lowered on the cotton fabric and the distance from the fabric to the hanging surface 41 is 2 cm, 10 cm, and 20 cm, the wrinkle level is evaluated when a shot is ejected once from each distance. did.

  As shown in FIG. 14, the longer the steam distance (shot ejection length) injected from the hanging surface 41 during shot ejection, that is, the higher the steam pressure, the better the wrinkle of the fabric can be extended. When the distance to the hanging surface 41 was 2 cm or 10 cm, it was confirmed that the evaluation of the wrinkle level “2” defined in JIS C 9804 was obtained when the shot ejection length was 120 cm or more. Therefore, in the iron of the present embodiment, the steam concentration ejection hole 43 is set with a target value of a shot ejection length of 120 cm so that the wrinkle extension of the level “2” can be achieved especially in the “concentration” side of the shot ejection. Number, range, and opening area. In addition, in the “dispersion” side shot ejection, the number, range, and opening area of the steam concentration ejection holes 43 are defined by setting the shot ejection length to be 80 cm.

  FIG. 15 shows a comparison result of performance between the conventional product and this embodiment. The shot ejection amount per time was 0.7 ml for both the conventional product and this embodiment. In this embodiment, the shot ejection length that is equal to or greater than the target value is measured for both “concentrated” and “dispersed” shot ejections. In terms of shots, it was found that the range of steam jet from the iron body 1 was narrowed from 30 cm to 10 cm in “concentrated” shot jets compared to “dispersed”.

  FIG. 16 shows the evaluation results of the test on how the state of the fabric changes before and after the shot ejection. In this test, a weight of 500 g was lowered on a cotton fabric, a shot was ejected once at a distance of 10 cm from the fabric and left for 1 minute, and then evaluated in comparison with the wrinkle level comparison chart shown in FIG. As a result, the wrinkle level changes from “7” to “4” before and after the shot injection in the “dispersion” side shot ejection, and the wrinkle level becomes “4” before and after the shot injection in the “concentration” side shot ejection. 7 ”to“ 5 ”(“ 2 ”when the diameter of the sprayed area is 5 cm). In other words, it was confirmed that the wrinkle was effectively removed with the “concentrated” shot, although the range of wrinkle extension was narrow.

  FIG. 17 shows the evaluation results of the test for the difference in the amount of moisture adhering to the fabric in the shot ejection. In this test, shot ejection was performed 10 times from a height of 2 cm, 10 cm, and 20 cm on the cotton fabric, and the amount of water adhering to the fabric was measured. As a result, in the “dispersion” side shot ejection, the amount of water reaching the fabric decreases significantly as the distance to the fabric increases as the shot ejection length becomes shorter than the “concentration” side shot ejection. However, in the “concentrated” side shot ejection, the amount of water reaching the fabric does not decrease even when sprayed at a distance of 20 cm from the fabric. In other words, in the “concentration” side of the shot ejection, more moisture can be intensively contained in the fabric, and stubborn wrinkles can be removed.

  Next, the outer shape of the iron body 1 in the present embodiment will be described with reference to FIG. In this figure, for convenience of explanation, the configuration of each part described above is partially omitted. The outer surface of the iron body 1 to which the tank assembly 17 is attached is such that the handle portion 24 of the handle 16 is located behind the uppermost end 91 at the highest position with the hanging surface 41 of the base 11 placed on a flat floor. Is provided. The rear end 24A of the grip portion 24 is opened without being connected to the base portion 25, and has a so-called open handle shape in which a hand can be inserted from the rear end side of the iron body 1 and the grip portion 24 can be gripped.

  In addition, on the front side of the iron body 1, a front end 93 that protrudes forward most forward is formed on the front surface 93 from the uppermost end 91 to the lowermost end 92 that is the lower end of the cover 15. That is, when the front surface 93 of the iron body 1 is unilaterally directed from the uppermost end 91 to the lowermost end 92 and forward of the iron body 1, the positions of the lowermost end 92 and the refront end 94 coincide with each other. In the embodiment, the positions of the lowermost end 92 and the refront end 94 do not coincide with each other. Preferably, the refront end 94 is positioned on the tank assembly 17, so that the front front 93 of the iron body 1 extends from the refront end 94 to the lowermost end 92. A reverse warped portion 95 curved in a convex shape toward the rear of the iron body 1 is formed.

  By the way, the conventional iron has a shape in which the front surface 93 of the iron body 1 is unidirectionally directed to the front of the iron body 1 from the uppermost end 91 to the lowermost end 92. It is difficult to arrange the pump device 62 that moves the 71 in the vertical direction on the front side of the tank assembly 17 and thus the iron body 1. Therefore, the mechanism that can be mounted on the front side of the iron body 1 is restricted, and the center of gravity of the iron body 1 is naturally positioned at the rear, and the rear end 24 </ b> A of the handle portion 24 that serves as the grip portion of the handle 16 is particularly In the open handle shape that is not connected, there is an anxiety that the hand that grips the handle portion 24 slides down from the rear end 24A.

  However, in the present embodiment, a reverse warp portion 95 directed toward the rear of the iron body 1 is formed on the front surface 93 of the iron body 1, and the number of mechanisms that can be mounted therein is increased, thereby providing the interior of the tank assembly 17. The pump device 62 and the like can be disposed on the front side of the conventional device. As a result, the center of gravity of the iron body 1 is moved forward, and even if it is an open handle shape, anxiety when gripping the handle portion 24 of the handle 16 can be eliminated.

  As described above, the iron according to the present embodiment includes the heater 31 as a heating means, the iron body 1 as a main body including the tank assembly 17 that stores liquid water, and the hanging surface 41 at the bottom. A base 11 heated by the heater 31, and a concentration side vaporization chamber 32 and a second vaporization chamber which are provided in the base 11 and serve as a first vaporization chamber which receives supply of water from the tank assembly 17 and generates steam. One or a plurality of steam concentrating jets as a steam concentrating jet part that is provided in a concentrated manner at one location near the front of the central portion of the hanging surface 41 and that discharges steam generated in the concentrating side vaporizing chamber 32. A hole 43 and a steam-dispersed spray hole 44 serving as a steam-dispersed spray portion that is provided in a substantially dispersed manner on the hooking surface 41 and ejects steam generated in the dispersion-side vaporization chamber 33. Eteiru.

  In this case, the steam is intensively ejected from the steam concentrating orifices 43 provided in a region of the hanging surface 41 corresponding to the concentrated side vaporizing chamber 32, while corresponding to the dispersion side vaporizing chamber 33. Steam can be ejected from different regions of the hanging surface 41 as needed by widely dispersing and ejecting the steam from the steam dispersed ejection holes 44 that are dispersed and provided on almost the entire hanging surface 4.

  Further, in the present embodiment, a concentration / dispersion switching lever 21E is further provided as a switching means that enables switching of the steam ejection from either the steam concentration ejection hole 43 or the steam dispersion ejection hole 44, and is provided at the upper part of the iron body 1. A handle 16 is provided, and a concentration / dispersion switching lever 21E is disposed in front of the iron body 1 with respect to the handle 16.

  In this way, the concentration / dispersion switching lever 21 is provided in front of the iron body 1 with respect to the handle 16, so that the concentration / dispersion switching lever 21 can be operated with a finger while holding the handle portion 24 of the handle 16 by hand. In addition, the spray of steam can be switched to either concentrated or dispersed, and an iron that is easy to use can be provided.

  In addition, since the concentration / dispersion switching lever 21 is formed integrally with the cylinder member 70 constituting the pump device 62 as an effect of the embodiment, the number of parts inside the tank assembly 17 can be reduced. In addition, since the concentration / dispersion switching lever 21 is provided so as to project from one side surface of the tank body 17 so as to rotate in the front-rear direction, the concentration / dispersion switching lever 21 is moved to the concentration / dispersion switching lever 21 while holding the handle portion 24 of the handle 16 by hand. By simply moving your finger in the forward / backward direction with your finger, you can easily switch the steam jet to either concentrated or dispersed.

  Further, since the at least one steam concentrated ejection hole 43 is provided immediately below the steam exhaust hole 37 adjacent to the steam exhaust hole 37, the steam is increased from the steam exhaust hole 37 through the steam concentrated ejection hole 43 with the increased injection pressure. Can be ejected.

  Further, the handle 16 of the present embodiment has a shape in which the rear end 24A of the handle portion 24 is opened without being connected to the iron body 1, and the front surface 92 of the iron body 1 faces the rear of the iron body 1. A reverse warped portion 95 curved in a convex shape is formed.

  In this case, a reverse warp portion 95 directed toward the rear of the iron body 1 is formed on the front surface 92 of the iron body 1, and the center of gravity of the iron body 1 is moved forward by increasing the number of mechanisms that can be mounted on the front side of the iron body 1. Even if it is an open handle shape, it is possible to wipe away anxiety when gripping the handle 16.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, as in this embodiment, the base is not limited to the one having only two vaporization chambers, but has three or more vaporization chambers, or another ejection portion other than the steam concentration ejection portion and the steam dispersion ejection portion. What exists in a hanging surface is interpreted as being contained in the iron of this invention.
