On the other hand, when the concentration / dispersion switching lever 31E is slid in the rotational biasing direction of the torsion spring 81 from the state where the claws 69A, 69B and the stoppers 79A, 79B are engaged and locked, the claw 69A, 69B and the stoppers 79A, 79B The engagement is released and the concentration / dispersion switching lever 31E returns to the original position by the urging force of the torsion spring 81. Note that another urging body instead of the torsion spring 81 may be used.

  As shown in FIG. 10, one water supply hole 83, two concentrated side water discharge holes 84 </ b> A, and a dispersion side water discharge hole 84 </ b> B are formed in the bottom surface portion of the cylinder holding portion 64 at predetermined intervals. . The water supply hole 83 communicates with the storage chamber 55 inside the tank assembly 13. Further, as shown in FIG. 14, in the tank assembly 13, the concentrated side water discharge hole 84A communicates with the concentrated side water discharge path 85A, and the dispersion side water discharge hole 84B communicates with another dispersion side water discharge path 85B. When the tank assembly 13 is attached to the front part of the main body 1, the front end opening of the concentrated side water discharge passage 85A communicates with the concentrated side auto valve 47A in a watertight state, and the front end opening of the dispersion side water discharge passage 85B is also connected to the dispersion side auto valve. It is configured to communicate with 47B in a watertight state. In FIG. 10, the opening areas of the concentration side water discharge holes 84A and the dispersion side water discharge holes 84B are indicated by hatching.

  Further, on the bottom surface of the rotating cylinder member 65, there is a single curved elongated hole 86 that allows the inside of the cylinder member 65 and the water supply hole 83 to communicate with each other regardless of the operation position of the concentration / dispersion switching lever 31E. / Concentration guide hole 87A that enables communication between the inside of the cylinder member 65 and the concentration side water discharge hole 84A when the dispersion switching lever 31E is switched to the “concentration” side that is the first position, and the concentration / dispersion switching lever Dispersion guide holes 87B that allow the inside of the cylinder member 65 to communicate with the dispersion-side water discharge holes 84B when the 31E is switched to the “dispersion” side, which is the second position, are formed.

  FIG. 10 shows the state inside the tank assembly 13 when the concentration / dispersion switching lever 31E is located on the “concentration” side by a solid line, and the concentration / dispersion switching lever 31E is located on the “dispersion” side. The state inside the tank assembly 13 at this time is indicated by a one-dot chain line. When the concentration / dispersion switching lever 31E is on the “concentration” side, that is, the knob 70 is positioned in front of the iron body 1, the cylinder member 65 rotates in one direction against the bias of the torsion spring 81. The claws 69A and 69B of the switching means 75 get over the stoppers 79A and 79B and are engaged and locked. Therefore, the inside of the cylinder member 65 and the water supply hole 83 communicate with each other through the curved long hole 86, and the hole positions of the concentrated guide hole 87A and the concentrated side water discharge hole 84A coincide with each other. 84A communicates. On the other hand, when the concentration / dispersion switching lever 31E is on the “dispersion” side, that is, the knob 70 is located rearward, the engagement lock between the claws 69A and 69B of the switching means 75 and the stoppers 79A and 79B is released. The cylinder member 65 is rotated in the other direction by the biasing force of the torsion spring 81. Therefore, the inside of the cylinder member 65 and the water supply hole 83 communicate with each other through the curved long hole 86, and the positions of the dispersion guide hole 87B and the dispersion side water discharge hole 84B coincide with each other. 84B communicates.

  As shown also in FIG. 14, a concentrated side cylindrical portion 89 </ b> A and a dispersion side cylindrical portion 89 </ b> B that extend downward are integrally formed on the bottom surface portion of the cylinder holding portion 64. These cylindrical portions 89A and 89B are attached to a common packing 90 in a watertight state, and form a concentrated side water discharge passage 85A that penetrates the inside of the packing 90 from the inside of the concentrated side cylindrical portion 89A and opens the tip (lower end). Then, a dispersion-side water discharge passage 85B is formed which penetrates the inside of the packing 90 from the inside of the dispersion-side cylinder portion 89B and similarly has an open end. On the proximal end side of the concentration side water discharge passage 85A, a concentration side valve mechanism that constantly biases the ball valve 92A with a spring 91A in a direction to close the concentration side water discharge hole 84A is provided, and on the proximal end side of the dispersion side water discharge passage 85B. Is provided with a dispersion-side valve mechanism that constantly biases the ball valve 92B with a spring 91B in a direction to close the dispersion-side water discharge hole 84B.

  These valve mechanisms can prevent water from being discharged from the pump device 52 to the outside of the tank assembly 13 as long as the pump device 52 is not operated by pushing the shot button 31B. When the shot button 31B is pushed, the water fed into the cylinder member 65 from the storage chamber 55 is pushed out, and when the concentration / dispersion switching lever 31E is positioned on the “concentration” side, the elasticity of the spring 91A The ball valve 92A opens the concentration side water discharge hole 84A against this, and a large amount of water is discharged from the concentration side water discharge passage 85A to the concentration side auto valve 47A, and the concentration / dispersion switching lever 31E is positioned on the “dispersion” side. In this case, the ball valve 92B opens the dispersion-side water discharge hole 84B against the elasticity of the spring 91B, and the dispersion-side auto valve 47 extends from the dispersion-side water discharge path 85B. Water and has a configuration that is discharged in large quantities.

  Inside the tank assembly 13, the water in the storage chamber 55 sent out through the valve device 51 and the pump device 52 is exposed to the lower surface side of the tank base 59 and mounted on the concentration side discharge port and the dispersion side discharge port ( A flow guide portion 94 is provided that leads to neither (not shown). The flow guide portion 94 has a mounting concave portion 95 formed on the upper surface of the tank base 59 serving as the inner bottom surface of the tank assembly 13 and a shape suitable for the mounting concave portion 92 and is disposed facing the valve device 51 and the pump device 52. It is comprised by the plate-shaped pressing member 96 made. The pressing member 96 is made of the same thermoplastic resin as the tank base 59 and is fixedly attached to the mounting recess 92 by ultrasonic welding in order to press the valve body of the valve device 61 described above against the tank base 59. When the tank assembly 13 is mounted on the iron body 1, the concentration side discharge port of the tank base 59 communicating with the concentration side water discharge passage 85 </ b> A and the concentration side auto valve 47 </ b> A communicate with each other in a watertight state, and the dispersion side water discharge passage. The dispersion-side discharge port of the tank base 59 communicating with 85B and the dispersion-side auto valve 47B communicate with each other in a watertight state.

  FIG. 15 shows a fluid path from the storage chamber 55 to the ejection hole 9 through the pump device 52. In the figure, reference numeral 101 denotes a continuous flow path from the discharge hole 84 serving as an outlet of the pump device 52 to the discharge hole 9 through the vaporization chamber 8. In this embodiment, when the two flow paths 101, that is, the concentration / dispersion switching lever 31E of the switching means 75 are positioned on the “concentration” side, the water from the pump device 52 is concentrated on the concentration side. Switching to the concentrated side flow path 101A as the first flow path through which the water which is guided to the concentrated side vaporization chamber 8A through the discharge hole 84A and heated and vaporized by the heater 3 is ejected from the steam concentrated ejection hole 9A as the concentrated steam S1. When the concentration / dispersion switching lever 31E of the means 75 is located on the “dispersion” side, water from the pump device 52 is guided to the concentration side vaporization chamber 8B through the dispersion side discharge hole 84B, and is heated and vaporized by the heater 3 there. The concentrated water is provided with a concentrated-side flow channel 101B as a second flow channel in which the discharged water is ejected from the steam dispersed ejection holes 9B as dispersed steam S2.

  The concentrated-side flow path 101A from the concentrated-side discharge hole 84A to the steam concentrated ejection hole 9A includes a concentrated-side steam space 37A serving as a steam passage in addition to the concentrated-side water discharge path 85A serving as the water passage and the concentrated-side water passage 46A. The concentration side auto valve 47A and the concentration side vaporization chamber 8A are arranged in the middle. Further, the dispersion-side flow path 101B from the dispersion-side discharge hole 84B to the steam dispersion ejection hole 9B has a dispersion-side steam space 37B serving as a steam passage in addition to the dispersion-side water discharge passage 85B serving as a water passage and the dispersion-side water passage 46B. The dispersion-side auto valve 47B and the dispersion-side vaporization chamber 8B are disposed in the middle. The concentration side flow path 101A and the dispersion side flow path 101B, including the vaporization chamber 8 and the ejection hole 9, are provided separately, and the position of the concentration guide hole 87A is set to the concentration side discharge by the switching means 75. When the concentration side channel 101A is switched to the open state so as to coincide with the hole 84A, the concentrated steam S1 having a narrow ejection range and a long stroke is ejected from the steam concentration ejection hole 9A serving as the tip outlet, and the switching means. 75, when the position of the dispersion guide hole 87B coincides with the dispersion-side discharge hole 84B and the dispersion-side flow path 101B is switched to the open state, the steam-concentrated ejection holes from the steam dispersion-ejection holes 9B serving as the front end outlets. In a region different from 9A, the dispersed steam S2 having a wide ejection range and a short stroke is ejected.

  The number of the flow paths 101 that can be switched to the closed state by switching only one of them by the switching means 75 may be two or more as long as the space of the iron body 1 allows. Also in this case, each flow path 101 including the vaporization chamber 8 and the ejection hole 9 is provided separately so as not to be connected in the middle, and one flow path 101 that is opened by the switching means is provided. By selectively switching, steam having different ejection ranges and strokes for each channel 101 can be effectively ejected from different regions of the base 4 to clothing or the like.

  Next, in the above-described configuration, the operation relating to the steam function will be described. The water inlet lid 14 is opened and closed, a predetermined amount of water is accommodated in the storage chamber 55 of the tank assembly 13, and the tank assembly 13 is attached to the iron body 1. Set it forward. Subsequently, the iron body 1 is placed on the placing table, and the temperature setting / off button 31D is pushed in the power supply state in which the power supply voltage is supplied to the iron body 1, and the cloth that is the object of ironing, etc. Set the temperature according to. As a result, in the iron body 1, the temperature control device 33 controls the heater 3 to be cut off so that the temperature of the base 4 detected by the temperature detecting means approaches the temperature set by the temperature setting / off button 31D. Thus, the base 4 including the concentrated side vaporizing chamber 8A and the dispersion side vaporizing chamber 8B is heated.

  Here, when the user uses the steam function, when the steam / dry switching lever 31A is switched to the “steam” side, the needle mechanism 61 of the valve device 51 rises in conjunction with it, and the valve body opens, and the flow guide Water can be distributed from the portion 94 to the dispersion side water passage 46B through the dispersion auto valve 47B. When the steam / dry switching lever 31A is switched to the “dry” side, the needle mechanism 61 is lowered to close the valve body, and the flow of water from the tank assembly 13 to the dispersion side water passage 46B is interrupted. In this case, the iron body 1 can be used as a dry iron in which steam is not ejected from all the ejection holes 9.

  Immediately after the heating of the base 4 by the heater 3 is started, the base 4 does not reach the vaporization temperature of water, the bimetals 49A and 49B attached to the base 4 are in a return state, and the auto valves 47A and 47B are Both are blocked. Therefore, in this case, even when the steam / dry switching lever 31A is switched to the “steam” side, the water flow from the tank assembly 13 is blocked by the auto valve 47B, and from there on the steam dispersion jet hole 9B. It is possible to prevent water droplets that are not vaporized from being ejected when ironing.

  Thereafter, when the base 4 is sufficiently heated and rises above the vaporization temperature of water, the bimetals 49A and 49B that have been in the restored state are transformed into an inverted state, and the auto valves 47A and 47B are both opened. Therefore, in this case, with the steam / dry switching lever 31A switched to the “steam” side, the water in the tank assembly 13 is guided to the water passage 46B through the auto valve 47B, and the steam generated in the dispersion side vaporization chamber 8B. However, it becomes possible to eject from the corresponding steam dispersion ejection holes 9B.

  On the other hand, in order to perform so-called shot ejection that temporarily increases the amount of steam ejection, the shot button 31B protruding above the tank assembly 13 is pushed. At this time, depending on the position of the concentration / dispersion switching lever 31E operated by the user, the steam ejection can be switched between “concentration” and “dispersion”.

  Specifically, when the knob 70 of the concentration / dispersion switching lever 31E protruding from one side of the tank assembly 13 is moved from the “dispersion” side to the “concentration” side, the urging force of the torsion spring 81 is resisted. The cylinder member 65 rotates in one direction, the claws 69A and 69B get over the stoppers 79A and 79B, and the cylinder member 65 and the concentration / dispersion switching lever are at positions where the claws 69A and 69B engage with the stoppers 79A and 79B. 31E is held. Accordingly, the inside of the cylinder member 65 and the water supply hole 83 communicate with each other through the curved long hole 86, and the inside of the cylinder member 65 and the concentrated side water discharge hole 84A communicate with each other through the concentrated guide hole 87A, while the dispersion side water discharge hole 84B The bottom of the cylinder member 65 is blocked. Accordingly, when the piston 66 is pushed up together with the shot button 31B by the repulsive force of the elastic body 67, the water stored in the storage chamber 55 is sucked into the cylinder member 65 through the water supply hole 83 inside the tank assembly 13. Next, when the piston 66 is pushed together with the shot button 31B against the repulsive force of the elastic body 67, the water sucked into the cylinder member 65 passes through the concentrated side water discharge passage 85A from the concentrated side water discharge hole 84A. It is discharged and guided from the concentrated side auto valve 47A to the concentrated side water passage 46A on the upper surface side of the base 4.

  Therefore, when the concentration / dispersion switching lever 31E is located on the “concentration” side, only the water guided to the concentration side water passage 46A temporarily increases and drops into the dropping receiving portion 36A of the concentration side vaporization chamber 8A. The steam vaporized in the concentrated side vaporizing chamber 8A is guided from the concentrated side steam space 37A to the steam concentrated ejection hole 9A, and the ejection range is narrowed from the steam concentrated ejection hole 9A provided in one area of the hanging surface 41. Steam S1 having a long stroke can be concentrated and ejected on a cloth or the like.

  The ball valve 92A provided in the concentration side water discharge passage 85A is movable according to the internal pressure of the cylinder member 65, and closes the concentration side water discharge passage 85A while sucking water into the cylinder member 65. When water is discharged from the inside of 65, the concentrated side water discharge passage 85A is opened.

  On the other hand, when the concentration / dispersion switching lever 31E is moved from the “concentration” side to the “dispersion” side, the engagement between the claws 69A and 69B of the cylinder member 65 and the stoppers 79A and 79B is released. The cylinder member 65 is rotated in the other direction by the urging force, and the cylinder member 65 and the concentration / dispersion switching lever 31E are held at predetermined positions. Accordingly, the inside of the cylinder member 65 and the water supply hole 83 communicate with each other through the curved long hole 86, and the inside of the cylinder member 65 and the dispersion side water discharge hole 84B communicate with each other through the dispersion guide hole 87B, while the concentrated side water discharge hole 84A has The bottom of the cylinder member 65 is blocked. Accordingly, when the piston 66 is pushed up together with the shot button 31B by the repulsive force of the elastic body 67, the water stored in the storage chamber 55 is sucked into the cylinder member 65 through the water supply hole 83 inside the tank assembly 13. Next, when the piston 66 is pushed together with the shot button 31B against the repulsive force of the elastic body 67, the water sucked into the cylinder member 65 passes through the dispersion-side water discharge passage 85B from the dispersion-side water discharge hole 84B. Discharged and guided from the dispersion-side auto valve 47B to the dispersion-side water passage 46B on the upper surface side of the base 4.

  Therefore, when the concentration / dispersion switching lever 31E is positioned on the “dispersion” side, only the water guided to the dispersion-side water passage 46B temporarily increases and drops into the dripping receiver 36B of the dispersion-side vaporization chamber 8B. The steam vaporized in the dispersion side vaporization chamber 8B is guided from the dispersion side steam space 37B to the steam dispersion ejection holes 9B, and the steam dispersion provided in a wide area of the hanging surface 41 different from the steam concentration ejection holes 9A. From the ejection hole 9B, the steam S2 having a wide ejection range and a short stroke can be dispersed and ejected on a cloth or the like.

  Further, the ball valve 92B provided in the dispersion side discharge path 80B moves according to the internal pressure of the cylinder member 65, and closes the dispersion side discharge path 80B when sucking water into the cylinder member 65, while the cylinder member 65 When water is discharged from the inside of 65, the dispersion side discharge path 80B is opened.

  In the present embodiment, there is an advantage that the shot ejection can be switched between “concentration” and “dispersion” by operating the switching means 75 according to the usage 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, steam is ejected from the steam concentrated ejection holes 9A concentrated on one area of the hooking surface 41 while increasing the steam pressure. It is possible to satisfactorily perform wrinkle stretching, and in the case of shot ejection on the “dispersion” side, moisture can be given to the fabric over a wide range.

  In this embodiment, when the shot button 31B for increasing steam is pushed, the steam is ejected from either “concentration” or “dispersion”, but the steam / dry switching lever 31A is moved to the “steam” side. It is also possible to adopt a configuration in which steam is ejected from either “concentration” or “dispersion” even during normal steam ejection without switching and pressing the shot button 31B. Furthermore, in addition to the concentration side channel 101A and the dispersion side channel 101B, another channel 101 is added to switch the switching means 75 so that the area of the hooking surface 41 other than “concentration” or “dispersion”. It is also possible to eject steam with a range and stroke different from “concentration” and “dispersion”.

  In the present embodiment, a slidable concentration / dispersion switching lever 31E is provided as an operation lever operated by the user of the switching means 75 on the right side as viewed from the front of the iron body 1, and the left side facing this A tank lock button 15 that can be pushed is provided as an operation button for detaching the tank assembly 13 from the iron body 1. The reason for this is that when the user is right-handed and the concentration / dispersion switching lever 31E is located in front of the grip portion 25 and is on the right side of the iron body 1, the grip portion 25 is held with the right hand by ironing or the like. If the tip end surface of the knob 70 is slid with the thumb while gripping, not only can the steam spray from the base 4 be switched between concentrated and dispersed, but the tank button 15 can be moved to the left side of the iron body 1. The tank assembly 13 can be easily detached from the iron body 1 by pressing the tank lock button 15 with the thumb as it is from the state where both sides of the tank assembly 13 are sandwiched with the right hand from the front side of the iron body 1. Because it can.

  Therefore, when the user is left-handed, the tank lock button 15 may be disposed on the right side of the iron body 1, and the concentration / dispersion switching lever 31E may be disposed on the left side of the iron body 1. Two types of tank assemblies 13 suitable for the dominant and left-handed may be prepared, and one of them may be mounted on the iron body 1 according to the user's dominant hand. As a result, it is possible to easily eject steam from different areas of the base 4 by operating the concentration / dispersion switching lever 31E as necessary from the state in which the grip portion 25 is gripped by hand. Can provide.

  In the present embodiment, a switching means 75 including a concentration / dispersion switching lever 31E exposed to the outside so that a user can operate and a cylinder member 65 that rotates in cooperation with the concentration / dispersion switching lever 31E is configured. Then, depending on the rotational position of the cylinder member 65, water sucked into the cylinder member 65 is selectively ejected as the concentrated steam S1 from the steam concentrated ejection hole 9A or as the dispersed steam S2 from the steam dispersed ejection hole 9B. When the concentration / dispersion switching lever 31E is slid in the direction in which the concentrated steam S1 is ejected from the steam concentrated ejection hole 9A, a stopper 79A that gets over the claws 69A and 69B of the cylinder member 65 and locks it. , 79B are provided integrally with the cover member 80 inside the tank assembly 13. As a result, once the concentration / dispersion switching lever 31E is operated until the claws 69A, 69B of the cylinder member 65 get over the stoppers 79A, 79B, the switching means 75 does not become a halfway position, and the stopper 79A. , 79B, the switching means 75 can be engaged and locked at the position determined.

  The switching means 75 includes a torsion spring 81 that constantly biases the rotation of the cylinder member 65 in the direction in which steam is ejected from the steam dispersion ejection hole 9B. Therefore, when the engagement / lock between the claws 69A and 69B of the cylinder member 65 and the stoppers 79A and 79B is released by sliding the concentration / dispersion switching lever 31E, the urging force of the torsion spring 81 acts on the cylinder member 65. The switching means 75 including the cylinder member 65 can be urged to a position where the dispersed steam S2 is ejected from the steam dispersed ejection hole 9B.

  As described above, in the present embodiment, the combination of the stoppers 79A and 79B and the torsion spring 81 serving as the urging member allows the switching means 75 to be moved from the base 4 to the concentrated steam when the finger is not touching the concentration / dispersion switching lever 31E. It can be placed either at the position where S1 is ejected or at the position where dispersed steam S2 is ejected from the base 4, and steam ejection in an unintended state of the switching means 75 can be prevented. In particular, when the engagement means between the claws 69A and 69B of the cylinder member 65 and the stoppers 79A and 79B is released by urging the switching means 75 in a specific direction by the torsion spring 81, there is always one distributed side flow. Only the path 101B is opened, and the other concentrated side flow path 101A can be regulated to be always closed, and the switching means 75 can be prevented from stopping halfway.

  Concave and convex knurled eyes 76 are formed on the tip surface of the knob 70 of the concentration / dispersion switching lever 31E. Thereby, when the finger is pressed against the tip surface of the knob 70 and the concentration / dispersion switching lever 31E is slid back and forth, it is possible to prevent the finger from slipping and becoming difficult to operate. Further, the knob 70 is normally positioned on the “dispersion” side that is the rear side of the slide groove 73 by the bias of the torsion spring 81, and when the slide operation is performed forward along the slide groove 73 from the slide groove 73, On the “concentration” side which is the front side, the claws 69A and 69B of the cylinder member 65 and the stoppers 79A and 79B are engaged, and the concentration / dispersion switching lever 31E is set at that position. Therefore, normally, the dispersed steam S2 is ejected over a wide range from the steam dispersed ejection hole 9B, and when necessary, the concentrated / dispersed switching lever 31E is slid in front of the iron body 1 so that the concentrated steam S1 is ejected from the steam concentrated ejection hole 9A. It becomes possible to spout to a pinpoint.

  The stoppers 79A and 79B are both formed as elastic pieces that are more elastically deformed than the claws 69A and 69B. The elastic moduli of the stoppers 79A and 79B are determined by the degree of cut forming the stoppers 79A and 79B with respect to the massive cover body 80 of the cover member 78, and the cuts are deeper and the stoppers 79A and 79B are formed longer. It becomes easy to elastically deform. Therefore, when the concentration / dispersion switching lever 31E is slid to engage and lock the stoppers 79A and 79B and the claws 69A and 69B, or release the engagement lock, the claw 69A and 69B come before. The stoppers 79A and 79B are elastically deformed, and the force applied to the switching means 75 can be reduced.

  As described above, the iron of the present embodiment has a plurality of steam ejection holes 9 that become steam, a base 4 that is heated by the heater 3, and a tank that includes a storage chamber 55 that stores water that is liquid. A tank assembly 13 formed on the base 4, a vaporizing chamber 8 for heating and vaporizing water from the tank assembly 13, a cover 11 covering the upper surface side of the base 4, and a cover 11 disposed on the cover 11. A grip portion 25 having a cavity 28 made up of 12 and a handle cover 26, and a switching means 75 provided on the right or left side surface portion of the tank and including a concentration / dispersion switching lever 31E as a manually operable switching lever; , And a torsion spring 81 as an urging body that urges the switching means 75 to rotate in one specific direction. And here, the water from the tank assembly 13 is led from the discharge holes 84 of the pump device 52 to the respective vaporization chambers 8, and the concentrated side vaporization chambers are formed as a plurality of flow paths 101 for ejecting steam from the ejection holes 9. 8A and the concentrated side flow path 101A including the steam concentrated ejection holes 9A, and the dispersion side vaporization chamber 8B and the dispersion side flow path 101B including the steam dispersed ejection holes 9B are provided separately. One of the dispersion side channels 101B is configured to be switched to an open state.

  In this case, as the flow path 101 for ejecting steam, a plurality of concentration side flow paths 101A and dispersion side flow paths 101B are provided independently, and one flow path 101 that is opened by the switching means 75, that is, the concentration side. By selectively switching between the flow path 101A and the dispersion side flow path 101B, either the concentrated steam S1 or the dispersed steam S2 having different ejection ranges or strokes can be ejected. Further, by urging the switching means 75 in a specific direction by the torsion spring 81, only the dispersion-side flow path 101B, which is one flow path, is always open unless the switching means 75 is engaged and locked. The concentrated side flow path 101A, which is a path, can be regulated so as to be always closed, and the switching means 75 can be prevented from stopping halfway, and an easy-to-use iron can be provided.

  In the present embodiment, the surface of the switching means 75 is formed in an uneven knurled shape with knurled eyes 76.

  In this case, the finger contact at the time of operation of the switching means 75 is good, and slippage can be suppressed and operability can be improved.

  16-19 has shown the iron of 2nd embodiment of this invention. In addition, the same code | symbol is attached | subjected to the structure which is common in the iron of 1st embodiment, and the same description is abbreviate | omitted as much as possible in order to avoid duplication.

  In this embodiment, the sliding agent 111 for reducing the friction with clothes is given to the hanging surface 41 of the base 4. Separately, in order to enhance the hydrophilicity with the liquid heated by the heater 3 in the base 4, a hydrophilic film forming agent 112 is formed on the entire inner wall of the vaporizing chamber 8 where water is dropped. . The film forming agent 112 is a silicon-based inorganic compound such as colloidal silica, and the film forming agent 112 is diluted with water 113 having high hardness.

  The valve device 51 that is linked to the steam / dry switching lever 31A includes a steam opening / closing rod 116 that is a steam opening / closing member that is slidably supported in an upright state by a cylindrical support member 115 formed on the partition member 57, and a support member. A packing 117 provided on the bottom surface of the concave portion of the body 115, and a spring 118 as a biasing member that constantly urges the packing 117 toward the bottom surface of the concave portion of the support member to protect the close contact state of the mechanism movable chamber 56; The above-described needle mechanism 61 is configured. An elastic valve body 119 formed at the lower end of the steam opening / closing bar 116 is provided facing the center of the outflow hole 120 formed at the bottom of the tank assembly 13.

  Under the valve device 51, a water passage joint 121 serving as a water conduit communicating with the vaporization chamber is provided. The water flow joint 121 is disposed on the upper surface side of the cover 11, and a heat shield plate 122 that blocks heat from the base 4 is interposed between the water flow joint 121 and the base 4. A vaporization chamber lid 10 that covers the upper surface opening of the vaporization chamber 8 is provided below the heat shield plate 122. 124 is a nozzle provided in the middle of the water passage joint 121, and an opening / closing valve 125 for opening and closing the nozzle 124 is provided through an opening 126 provided in common for the heat shield plate 122 and the vaporization chamber lid 10. It protrudes downward toward the bimetal storage portion 50 that is a recess of the base 4. In the bimetal storage unit 50, an inversion-type bimetal 49 corresponding to a heat sensitive body is stored. When the vaporization chamber 8 in the vicinity of the bimetal storage unit 50 reaches a predetermined temperature, the bimetal 49 is contained in the bimetal storage unit 50. The nozzle 124 is opened by reversing and pushing up the on-off valve 125 against the bias of the spring 127.

  The temperature control device 33 provided in the grip 25 includes a switch unit 132 of the setting button 131 constituting the temperature setting / off button 31D and a plurality of light emitting diodes corresponding to the temperature display lamp 32, that is, the LED 133. A power storage device 134 such as a capacitor that stores and holds the set temperature and enables setting of the setting button 131 is mounted on the upper surface of the substrate 135 on which the pattern wiring is provided. The light from the LED 133 is transmitted through the sheet-like temperature display nameplate 136 attached to the surface of the grip portion 25 and displays the current set temperature.

  A water repellent coating 137 is formed on the surface of the outflow hole 120 through which the liquid flows out of the tank assembly 13. Here, as the water-repellent coating 137, a fluororesin-based coating is applied.

  In the present embodiment, when the steam / dry switching lever 31A is switched to the “steam” side, the steam opening / closing rod 116 of the valve device 51 rises in conjunction with it, and the valve body 119 opens the outflow hole 120. At this time, if the vaporizing chamber 8 has reached a predetermined temperature, the bimetal 49 is reversed and the nozzle 124 is opened, and the water stored in the tank assembly 13 passes through the nozzle 124 from the outflow hole 120. A normal amount of steam can be ejected from the ejection hole 9 by dripping into 8.

  On the other hand, when the steam / dry switching lever 31A is switched to the “dry” side against the bias of the spring 118, the steam opening / closing rod 116 is lowered, the valve body 119 closes the outflow hole 120, and the tank assembly. The flow of water from the inside of 13 to the vaporizing chamber 8 is blocked. Therefore, in this case, the iron body 1 can be used as a dry iron in which steam is not ejected from all the ejection holes 9.

  When a normal amount of steam is ejected, water inside the tank assembly 13 is dropped into the vaporizing chamber 8 through the outflow hole 120. Conventionally, a hydrophilic material such as a copper oxide film is formed on the surface of the outflow hole 120 as a film forming component. A proposal has been made to apply a water-resistant coating so that water can easily pass through the outflow hole 120. However, since the outflow hole 120 has a small hole shape, the surface tension of water acts, so that water does not drip from the outflow hole 120, steam does not come out from the ejection hole 9, and steam only comes out intermittently. There was a problem.

  Further, when ironing, due to the temperature rise of the iron body 1 itself by heating the base 4 with the heater 3, the water inside the tank assembly 13 is also warmed and bubbles are generated. When these bubbles are entangled in the small-hole-shaped outflow holes 120, there is a problem that steam is not emitted from the ejection holes 9 or steam is produced only intermittently. In order to smoothly eject the steam, Switching operation of the dry switching lever 31A was performed to remove the entanglement of bubbles, and the iron body 1 was shaken strongly back and forth to break the surface tension and forcibly eject steam.

  Therefore, in this embodiment, in order to eliminate such drawbacks and to stably eject steam from the ejection holes 9 without performing a troublesome operation, the surface of the outflow hole 120 is not a hydrophilic film but a water repellent film 137. Has been given. The water repellent coating 137 weakens the mutual attractive force between the water that has reached the outflow hole 120 from the inside of the tank assembly 13 and the surface of the outflow hole 120, so that surface tension is applied to the small outflow hole 120. Without being able to drop water smoothly. In particular, by applying a fluororesin-based coating as the water-repellent coating 137, even if the water temperature in the tank assembly 13 rises and bubbles are generated, bubbles are entangled in the outflow holes 120 due to the fluidity of the fluororesin. First, water can be dripped smoothly. Therefore, it is possible to stably and smoothly eject steam from the ejection holes 9 without performing troublesome operations, and provide an easy-to-use iron.

  Furthermore, in this embodiment, since the hydrophilic film forming agent 112 is adhered to the vaporizing chamber 8 inside the base 4, water is supplied to the vaporizing chamber 8 heated from the pump device 52 every time the shot button 31B is pressed. Even if a large amount is dripped at a high speed, the water that has touched the hydrophilic film forming agent 112 diffuses there and is surely vaporized in the middle of reaching the ejection hole 9. Thereby, only steam can be ejected from the ejection hole 9 without leaving a hot water drop, and clothes and the like can be comfortably ironed.

  Such technical features of the present embodiment can be applied to the iron of the first embodiment. For example, in the iron according to the first embodiment, the vaporization chamber 8 is divided into a concentration side vaporization chamber 8A and a dispersion side vaporization chamber 8B, and the concentration side ejection hole 9A is formed from the dropping receiving portion 36A of the concentration side vaporization chamber 8A. It is not possible to secure a sufficient distance between the concentration side passage 44A reaching the dispersion side and the dispersion side passage 44B from the dropping receiving portion 36B of the dispersion side vaporization chamber 8B to the dispersion side ejection hole 9B, but the inner walls of the concentration side passage 44A and the dispersion side passage 44B By covering the entirety with the hydrophilic film forming agent 112, only steam can be ejected from the concentrated side ejection hole 9A and the dispersion side ejection hole 9B without leaving any hot water droplets.

  The film forming agent 112 is not limited to the entire inner wall of the vaporizing chamber 8, but the vapor discharge holes 38 </ b> A and 38 </ b> B and the upper concave portions 39 </ b> A and 39 </ b> B formed in the base 5, and the bulging portions 40 </ b> A and 40 </ b> B formed in the hanging surface member 6. You may apply and form on the surface of all the inner walls which can contact water and steam at least inside the base 4 including the ejection holes 9A and 9B.

  In addition, a mixed liquid in which Ludox (registered trademark), pure water as water 113, and Contrex (registered trademark) are mixed at a ratio of 1: 6: 0. Alternatively, a film forming agent 112 that becomes a hydrophilic film may be formed. Ludox (Model No .: HS-40) is a colloidal silica aqueous dispersion with excellent antifouling properties, transparency and hydrophilicity. It is a coating composition that maintains surface hydrophilicity even at high temperatures. The component is hard water containing 234 mg of calcium and 37 mg of magnesium per 500 ml, and is added for the purpose of adding chalk to enhance the hydrophilicity in the base 4. Thereby, the film forming agent 112 excellent in adhesion and hydrophilicity is formed on the entire inner wall surface of the base 4.

  20-22 has shown the iron of 3rd embodiment of this invention. In addition, the same code | symbol is attached | subjected to the structure which is common in the iron of 1st embodiment and 2nd embodiment, and it abbreviate | omits as much as possible in order to avoid duplication.

  In FIG. 20 showing the overall configuration of the iron body 1, reference numeral 141 denotes a vibration motor as an electric vibrator incorporated in the iron body 1. The vibration motor 141 operates in response to a control signal from a temperature control device 33 (not shown here), and mechanical vibration generated thereby is a water supply path via an appropriate transmission mechanism 142. This is applied to the heat shield plate 122 described above. In addition, when the movable part of the vibration motor 141 can be directly connected to the heat shield plate 122, the transmission mechanism 142 may be unnecessary. In FIG. 20, the transmission path of vibration from the vibration motor 141 to the heat shield plate 122 by the transmission mechanism 142 is indicated by arrows.

  Reference numeral 144 denotes a tank water passage provided at the bottom of the tank assembly 13 and including the lower part of the valve device 51. Reference numeral 145 denotes a water flow portion provided on the upper surface side of the cover 11 and including the water flow joint 121. The tank water-passing part 144 and the water-passing part 145 are provided at positions where they contact each other when the tank assembly 13 is mounted on the iron body 1. A heat shield plate 122 is attached and fixed to the lower side of the water passage joint 121. When the tank assembly 13 is mounted on the iron body 1, if vibration is applied to the heat shield plate 122 by the vibration motor 141, the vibration is reduced. Is transmitted from the water flow joint 121 to the tank water flow portion 144.

  In addition, in FIG. 20, although one part structure is abbreviate | omitted not shown, the structure similar to 1st Embodiment or 2nd Embodiment is provided.

  21 shows the tank water passage 144 in a state where the water passage from the tank assembly 13 is closed, and FIG. 22 shows the tank water passage 144 in a state where the water passage from the tank assembly 13 is closed. Is shown. A valve body 119 serving as a needle of the valve device 51 is provided facing an outflow hole 120 formed in the center of the valve 146, and a valve 146 serving as a valve seat of the valve device 51 is attached to the bottom of the tank assembly 13. Is done.

  As described above, when the steam / dry switching lever 31A is switched to the “dry” side against the bias of the spring 118, the steam opening / closing rod 116 of the valve device 51 is lowered as shown in FIG. The valve body 119 comes into contact with the valve 146 in a state of being elastically deformed, and closes the outflow hole 120 in a watertight manner. Thereby, the water flow path from the inside of the tank assembly 13 to the vaporizing chamber 8 is blocked, and the iron body 1 can be used as a dry iron in which steam is not ejected from all the ejection holes 9.

  On the other hand, when the steam / dry switching lever 31A is switched to the “steam” side, as shown in FIG. 22, the steam opening / closing rod 116 of the valve device 51 rises, the valve body 119 moves away from the valve 146, and the valve body 119 A gap 147 is formed between the outer peripheral surface of the valve and the inner peripheral surface 146 of the valve. As a result, the water passage from the inside of the tank assembly 13 to the vaporizing chamber 8 is opened, and the water flowing from the gap 147 passes through the nozzle 124 when the vaporizing chamber 8 reaches a predetermined temperature and the bimetal 49 is reversed. A normal amount of steam can be ejected from the ejection hole 9 by dropping into the vaporizing chamber 8.

  Here, during normal use, water passes through the gap 147 between the small outflow holes 120 provided in the valve 146 without any problem. As described above, the iron body 1 is obtained by heating the base 4 with the heater 3. When the temperature in itself increases, the water in the tank assembly 13 is also warmed and bubbles B are generated. When the bubbles B adhere to the valve 146 and cannot be removed, the gap 147 is blocked by the bubbles B, and the water is discharged from the gap 147. The phenomenon that no longer occurs.

  Therefore, in this embodiment, in order to stably eject the steam from the ejection hole 9, the vibration is transmitted to the valve 146 provided in the valve device 51 of the tank assembly 13 by applying vibration to the heat shield plate 122. A vibration motor 141 is provided as a vibrator that eliminates the bubbles B adhering to the valve 146.

  Accordingly, the valve 146 that forms a water passage from the tank assembly 13 can be vibrated by the vibration motor 141 in a state where the water inside the tank assembly 13 is warmed, and the bubble B generated in the water is transferred to the valve 146. Without adhering, the phenomenon that the air bubbles B block the gap 147 can be prevented, and the steam can be stably ejected from the ejection holes 9.

  In addition, if the water-repellent coating 137 (not shown here) in the second embodiment is formed on the surface of the outflow hole 120, the steam can be ejected from the ejection hole 9 more stably.

  Further, when the iron of the present embodiment is a cordless iron that relays the mounting table and supplies power to the iron body 1, the vibration motor 141 is energized during power supply when the iron body 1 is placed on the mounting table. It is preferable to do this. That is, when the gripping part 25 is gripped by hand and the ironing body 1 is detached from the mounting table, the vibration motor 141 is not energized so that no mechanical vibration is transmitted to the gripping part 25. , You can avoid discomfort during use.

  Further, when the temperature of the base 4 detected by a temperature detecting means (not shown) reaches a predetermined value during power feeding with the iron body 1 placed on the mounting table, the vibration motor 141 is controlled to be energized. preferable. The bubble B is generated by the difference between the temperature of the water inside the tank assembly 13 and the temperature of the valve 146. Therefore, when the base 4 reaches a predetermined temperature due to the warming state of the base 4, the vibration motor 141 is turned off. By operating, the bubble B can be effectively eliminated, and unnecessary operation of the vibration motor 141 can be avoided, and the discomfort of the operation sound can be reduced.

  In addition, it is also possible to apply the technical feature of this embodiment to the iron of 1st embodiment or 2nd embodiment.

  FIGS. 23-25 has shown the iron of 4th embodiment of this invention. In addition, the same code | symbol is attached | subjected to the structure which is common in the iron of 1st embodiment-3rd embodiment, and it abbreviate | omits as much as possible in order to avoid duplication.

  FIG. 23 is a view of the inner surface, that is, the lower surface side of the base 5, and FIG. 24 is a view of the inner surface, that is, the upper surface side, of the hanging surface member 6. The base 4 of the second embodiment or the third embodiment is configured by attaching and fixing the illustrated inner surface of the base 5 and the inner surface of the hanging surface member 6 facing each other.

  23 and FIG. 24, 38 is a vapor discharge hole formed at the outlet of the vaporizing chamber 8, 39 is an upper recess formed in the lower surface of the base 5, and 40 is a concave bulge formed on the upper surface of the hanging surface member 6. A shot steam path 151 serving as a steam flow path from the vaporizing chamber 8 to the ejection hole 9 is formed inside the base 4 by the upper concave portion 39 and the bulging portion 40 that are partly opposed to each other. Is done. In addition, the arrow S in a figure has shown the flow of steam.

  The shot steam passage 151 corresponds to a mechanism for ejecting steam from the vaporization chamber 8 toward at least one ejection hole 9, and a specific one of the plurality of ejection holes 9 with the steam discharge hole 38 as a base end. A steam introduction portion 152 extending toward the ejection hole 9-1; a steam reservoir portion 153 which communicates with the steam introduction portion 152 and surrounds the specific ejection hole 9-1; and a steam reservoir portion 153 The vortex generator 154 provided in a spiral groove shape from the bottom surface toward the specific ejection hole 9-1 and the vapor reservoir 153 communicate with the ejection hole 9- other than the specific ejection hole 9-1 from the vapor reservoir 153. And a steam guide portion 155 extending toward the second side. In addition, on the upper surface side of the hook member 6, the specific jet hole 9-1 and its surroundings are disposed so that the steam reaching the steam guide portion 155 flows in a concentrated manner toward the specific jet hole 9-1. A cap 156 that covers a part of the steam guide 155 is provided.

  The specific ejection hole 9-1 is provided at the front center of the hanging surface 41, and the other ejection holes 9-2 are provided around the front of the hanging surface 41. The hole 9-1 is not particularly limited, and a plurality of specific ejection holes 9-1 may be provided. In the above-described shot steam passage 151, the steam reservoir 153 and the vortex generator 154 correspond to vortex generators that generate vortices in the steam ejected from the specific ejection holes 9-1.

  Next, the operation of the above configuration will be described with reference to FIG. For comparison, a steam flow path from the conventional vaporization chamber 8 is shown in FIG. Arrows S in these drawings indicate the flow of steam.

  First, the conventional steam flow path will be described. When the shot button 31B is pushed in a state where the base 4 is heated to a predetermined temperature, the pump device 52 is interlocked to temporarily move a large amount into the vaporizing chamber 8. Water is sent out, and water is heated and vaporized in the vaporizing chamber 8. As a result, the vapor generated in the vaporizing chamber 8 enters the shot vapor passage 151 ′ from the vapor discharge hole 38, but conventionally, the vapor from the vaporizing chamber 8 is directly guided to the ejection hole 9 along the shot vapor passage 151 ′. In addition, since it is configured to be ejected from the ejection hole 9 to the cloth or the like, there is a problem that the vapor diffuses in the vicinity of the ejection hole 9 and the permeation force to the cloth or the like is reduced. Therefore, when taking a stubborn wrinkle on a shirt or the like, it is necessary to operate the shot button 31B a plurality of times, which is inconvenient.

  On the other hand, the steam flow path of the present embodiment is the same as the conventional one until the steam generated in the vaporization chamber 8 enters the shot steam passage 151 from the steam discharge hole 38, but a specific ejection from the steam introduction part 152. The steam led to the steam reservoir 153 near the hole 9-1 is temporarily stored there, and then flows along the spiral vortex generator 154 toward the specific ejection hole 9-1. A vortex is spun from -1 toward the fabric. As described above, in the present embodiment, in order to cause the vortex to be swirled around the steam ejected from the specific ejection hole 9-1, the flow path by the steam reservoir 153 and the vortex flow generation section 154 is provided above the specific ejection hole 9-1. It is possible to increase the penetrating power of the steam to the cloth or the like by causing the steam to be swirled and thereby providing the propelling force to the steam itself.

  That is, in the present embodiment, at least one ejection hole 9 and an iron provided with a shot steam passage 151 serving as a path for guiding the steam from the vaporization chamber 8 to the ejection hole 9, ejects from a specific ejection hole 9-1. A steam reservoir 153 and a vortex generator 154 are provided as a vortex generator for causing the steam to vortex.

  Thereby, a vortex can be wound around the steam ejected from the specific ejection hole 9-1 to provide a propulsive force, and it is possible to realize a steam ejection having a stronger osmotic force than before.

  Furthermore, by providing a cap 156 as a cover member that covers a part of the vortex generator 154 so as to face at least the specific jet hole 9-1, the steam guide 155 is directed toward the specific jet hole 9-1. Thus, it is possible to concentrate and flow the steam without dispersing it, and it is possible to realize a steam jet having a stronger osmotic force from the specific jet hole 9-1.

  In addition, it is also possible to apply the technical feature of this embodiment to the iron of 1st embodiment-3rd embodiment.

  Similarly, a nozzle 124B is provided in the middle of the second passage from the dispersion pump device 52B to the dispersion side vaporization chamber 8B inside the water flow coupling 121, and an on-off valve 125B for opening and closing the nozzle 124B is provided with a heat shield. From the opening part 126B provided in common with the board 122 and the vaporization chamber lid | cover 10, it protrudes below toward the bimetal accommodating part 50B. The bimetal 49B is stored in the bimetal storage 50B, and when the vaporization chamber 8B near the bimetal storage 50B reaches a predetermined temperature, the bimetal 49B is reversed inside the bimetal storage 50B and resists the bias of the spring 127B. Then, the nozzle 124B is opened by pushing up the on-off valve 125B.

  Next, the operation at the time of ironing in the above-described configuration will be described. First, in the full-surface steam that ejects steam from the entire surface of the hanging surface 41, the user puts the iron body 1 into a power supply state and goes to the temperature setting / off button 31D. When an arbitrary temperature is set by the pushing operation, the heater 3 is energized and the temperature of the base 4 rises. When the base 4 reaches a certain temperature or more, the bimetals 49A and 49B are reversed to push up the on-off valves 125A and 125B, thereby opening the nozzles 124A and 124B.

  Further, when the dispersion shot button 31BB is pushed down with a finger, the pressure of the water sucked into the cylinder member 65B rises in conjunction with the piston 66B, the steel ball 176B is pushed down, and the dispersion side water supply hole 83B is hermetically sealed, Another steel ball 177B is pushed down to open the dispersion-side water discharge hole 84B. Therefore, when the nozzle 124B is open, the water is forced to flow from the water outlet 173B of the water flow joint 121 to the dispersion side vaporization chamber 8B through the junction 172 and heated by the heater 3 when the nozzle 124B is open. Due to the amount of heat in the dispersion-side vaporization chamber 8B, water instantly vaporizes into steam, and the steam emitted from the vapor discharge holes 38B of the dispersion-side vaporization chamber 8B passes through the steam dispersion discharge holes 9B as an increased amount of steam from the entire hanging surface 41. Erupted.

  Thereafter, when the finger is released from the dispersion shot button 31BB, the piston 66B is pushed up together with the shot button 31BB by the repulsive force of the elastic body 67B, and the pressure inside the cylinder member 65B is lowered. At this time, the steel ball 176B is pushed up to open the dispersion-side water supply hole 83B, whereas the steel ball 177B is pushed up and the dispersion-side water discharge hole 84B is hermetically sealed, so that the water stored in the storage chamber 55 is dispersed. It is sucked into the cylinder member 65B through the side water supply hole 83B. By repeating the operation on the dispersion shot button 31BB as described above, steam having a jet output greater than normal can be generated from the entire surface of the hanging surface 41.

  Similarly, in the concentrated steam that ejects steam from a part of the hanging surface 41, when the concentrated shot button 31BA is pushed down with a finger, the pressure of the water sucked into the cylinder member 65A increases in conjunction with the piston 66A, The steel ball 176A is pushed down to hermetically seal the concentrated side water supply hole 83A, and another steel ball 177A is pushed down to open the concentrated side water discharge hole 84A. Therefore, when the nozzle 124A is open, the water is forced to flow from the opening 171A through the concentration side auto valve 47A to the concentration side vaporization chamber 8A from the water outlet 173A of the water passage joint 121 and heated by the heater 3. Due to the amount of heat in the concentrated side vaporizing chamber 8A, water is instantly vaporized to become steam, and the steam discharged from the steam discharge hole 38A of the concentrated side vaporizing chamber 8A passes through a part of the hanging surface 41 through the steam concentrated discharge hole 9A. It is spouted out as an increase steam.

  Thereafter, when the finger is released from the concentrated shot button 31BA, the piston 66A is pushed up together with the concentrated shot button 31BA by the repulsive force of the elastic body 67A, and the pressure inside the cylinder member 65A is reduced. At this time, the steel ball 176A is pushed up to open the concentrated side water supply hole 83A, whereas the steel ball 177A is pushed up and the concentrated side water discharge hole 84A is hermetically sealed, so that the water stored in the storage chamber 55 is concentrated. The air is sucked into the cylinder member 65A through the side water supply hole 83A. By repeating the above operation on the concentrated shot button 31BA, it is possible to generate steam having a jet output that is higher than normal from a part of the hanging surface 41.

  Thus, in the present embodiment, by providing two pump devices 52 and two vaporization chambers 8, it is possible to switch the ejection range of the increased steam to the entire hanging surface 41 and a part of the hanging surface 41. Specifically, for example, for a large fabric, the dispersion pump device 52B is operated by the dispersion shot button 31BB, and the steam temporarily increased in the dispersion side vaporization chamber 8B By using the full-increase steam that is ejected from 9B, the uniform pump device 52A is operated by the centralized shot button 31BA for finely crumpled areas where water is uniformly applied to the fabric and is partially wrinkled. Then, by using concentrated concentrated steam that causes the steam temporarily increased in the concentrated side vaporizing chamber 8A to be ejected from a partial steam concentrated ejection hole 9A of the hanging surface 41, moisture is concentrated on the fabric. Can do. Therefore, depending on the type and state of the fabric, it is possible to selectively use the spray range of the increased steam, and the ironing time can be shortened.

  When the concentration pump device 52A is operated by forming the volume of the dispersion side vaporization chamber 8B larger than the volume of the concentration side vaporization chamber 8A as the two vaporization chambers 8 formed in the base 5 of the base 4. When the dispersion pump device 52B is operated, it is possible to change the momentum of the increased steam ejected from the hooking surface 41. In particular, in the concentrated increasing steam than the above-described full increasing steam, it is possible to eject steam with a strong momentum from the steam concentrated ejection hole 9A. It can be extended and an easy-to-use iron can be provided.

  As described above, the iron according to the present embodiment is a base 4 having the vaporizing chamber 8, a hooking surface 41 disposed as the lower surface of the base 4, and a handle that is provided above the base 4 and has the handle 12 at the top. A grip assembly 25, a tank assembly 13 serving as a water storage cassette tank disposed above the base 4, and a water supply that is a liquid from the tank assembly 13 according to the temperature of the base 4 disposed above the base 4. The bimetal 49 and the on-off valve 125 as an opening / closing device that adjusts the flow rate, the water passage joint 121 that guides water from the tank assembly 13 to the vaporizing chamber 8, and a large amount of water from the tank assembly 13 are supplied to the vaporizing chamber 8 at a time. When the centralized pump device 52A serving as the first pump device is operated, water from the tank assembly 13 is provided. Dispersion pump device 52B which is pumped to concentrated side vaporizing chamber 8A serving as the first vaporizing chamber, and partially increasing steam is ejected from steam concentrated spraying hole 9A serving as the first ejection hole of hanging surface 41, and serves as the second pump device. Is operated, the water from the tank assembly 13 is pumped to the dispersion side vaporization chamber 8B serving as the second vaporization chamber, and the increased amount of steam is ejected from the steam dispersion ejection holes 9B serving as the second ejection holes of the hanging surface 41. It has become.

  Therefore, when the centralized pump device 52A is operated and when the distributed pump device 52B is operated, the range in which the increased amount of steam is ejected from the hooking surface 41 can be changed, and the concentrated / dispersed as in the first embodiment. The switching lever 31E is not required, and it is possible to selectively use the range in which the increased amount of steam is ejected.

  In the present embodiment, the steam generated in the dispersion side vaporizing chamber 8B is ejected from the entire hanging surface 41 through the steam dispersed ejection holes 9B, while the steam generated in the concentrated side vaporizing chamber 8A is discharged to one part of the hanging surface 41. The dispersion side vaporization chamber 8B is formed to be larger than the concentration side vaporization chamber 8A.

  Therefore, when the centralized pump device 52A is operated and when the dispersion pump device 52B is operated, it is possible to change the momentum of the increased amount of steam ejected from the hooking surface 41, and it is possible to use the momentum of the increased amount of steam properly. Become.

  Furthermore, in this embodiment, depending on the selection of the pump device 52 to be operated, steam is ejected from a part of the hanging surface 41 from the concentrated side vaporizing chamber 8A through the steam concentrated ejection hole 9A, and steam is dispersed and ejected from the dispersion side vaporizing chamber 8B. Through the hole 9 </ b> B, it is configured such that steam can be selectively executed from the entire hanging surface 41.

  Therefore, by operating either the concentrated shot button 31BA or the distributed shot button 31BB and selecting the pump device 52 to be operated, it is possible to inject steam in the desired ejection range as it is.

  Next, another modification of the present embodiment is shown in FIGS. In each of these drawings, the water-permeable joint 121 of this example has an auto valve 47, an on-off valve 125, an opening 126, and a spring 127, while the nozzles 124A and 124B and the water outlets 173A and 173B. The two water outlets 173A are communicated with the concentrated side vaporizing chamber 8A, and the water outlet 173B is communicated with the dispersion side vaporizing chamber 8B.

  Along with this, only one concave bimetal storage portion 50 formed in the base 4 and one bimetal 49 stored in the bimetal storage portion 50 are disposed below the on-off valve 125. Further, only one pump device 52 is built in the tank assembly 13, and when the shot button 31B is pushed down with a finger, the piston 66A is interlocked to increase the water pressure inside the cylinder member 65, and the steel ball 176 is pushed down. The water supply hole 83 is hermetically sealed and another steel ball 177 is pushed down to open the water discharge hole 84. On the other hand, when the finger is released from the shot button 31B, the piston 66 is moved together with the shot button 31 by the repulsive force of the elastic body 67. When the pressure inside the cylinder member 65 is pushed up and the steel ball 176 is pushed up to open the concentrated water supply hole 83, the steel ball 177 is pushed up and the water discharge hole 84 is hermetically sealed. It has become.

  On the bottom surface of the nozzle 124B extending from the on / off valve 125 to the water outlet 173B, an inclined surface 180 is formed in which the on / off valve 125 side is low and the water outlet 173B side is high, and on the inclined surface 180 inside the nozzle 124B. In addition, a steel ball 181 which is a valve body is arranged to be able to roll. When the iron body 1 is in a horizontal state, the steel ball 181 moves to the on-off valve 125 side to open the water outlet 173B, and when the iron body 1 is in a vertical state, the steel ball 181 moves to the water outlet 173B side. And configured to close the water outlet 173B. On the other hand, the nozzle 124A extending from the on-off valve 125 to the water outlet 173A is always open without providing a valve body.

  In this example, when the iron body 1 is horizontal, that is, when the hanging surface 41 is pressed against clothes laid on an ironing board (not shown) and the ironing operation is performed, the steel ball 181 moves to the front of the nozzle 124B, Since the water outlet 173B is in an open state, when the shot button 31B is pushed down, water inside the cylinder member 65 is dropped into the concentrated side vaporizing chamber 8A through the nozzle 124A and dispersed side vaporized through the nozzle 124B. It is also dropped into the chamber 8B, and an increased amount of steam is jetted from the entire hanger surface 41 through the steam concentrating ejection holes 9A and the steam dispersion ejection holes 9B.

  In addition, when the iron body 1 is self-supporting, that is, when the hanging surface 41 is directed to clothes hung on a hanger (not shown), the steel ball 181 moves to the rear of the nozzle 124B and closes the water outlet 173B. When the button 31B is pressed down, the water inside the cylinder member 65 flows only to the nozzle 124A and is dripped into the concentration side vaporization chamber 8A, and an increased amount of steam is injected from a part of the hanging surface 41 through the steam concentration discharge hole 9A. The

  Therefore, also in this case, by providing the vaporizing chamber 8 in two parts, the ejection range of the increased steam can be switched between the entire hanging surface 41 and a part of the hanging surface 41. Therefore, depending on the type and state of the fabric, it is possible to selectively use the range of ejection of the increased steam, and the ironing time can be shortened.

  Further, depending on the posture of the iron body 1, the steam is ejected from a part of the hanging surface 41 through the steam concentrating jet hole 9A from the concentrating side vaporizing chamber 8A, and the hung through the steam dispersing jet hole 9B from the dispersion side vaporizing chamber 8B. Since the operation of ejecting steam from the entire surface 41 is automatically selected, it is possible to inject steam into a desired ejection range without selecting it one by one on the user side.

  Furthermore, in this case as well, by forming the volume of the dispersion side vaporization chamber 8B larger than the volume of the concentration side vaporization chamber 8A, the momentum of the increase steam ejected from the hanging surface 41 can be changed, and the increase steam momentum is used properly. It becomes possible.

  In addition, it is also possible to apply the technical feature of this embodiment to the iron of 1st embodiment-4th embodiment.

  40 to 43 show an iron according to a sixth embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the structure which is common in the iron of 1st embodiment-5th embodiment, and it abbreviate | omits as much as possible in order to avoid duplication.

  In the present embodiment, only one pump device 52 is installed in the tank assembly 13, and the auto valve 47, the nozzle 124, the on-off valve 125, the opening 126, the spring 127, the water, A configuration in which only one outlet 173 and only one vaporizing chamber 8 of the base 4 are provided, and steam is ejected from all the ejection holes 9 formed in the hooking surface 41 through the vapor discharge holes 38 of the vaporizing chamber 8. It has become. However, as described in the first to fifth embodiments, these configurations may be appropriately increased to a plurality.

  In order to increase the number of times the increased steam is used and the duration of the steam ejection, it has been conventionally performed to increase the weight of the base 4 having the vaporizing chamber 8 to ensure the heat capacity. However, since the weight of the iron body 1 increases with the base 4, when the ironing operation is performed or when the iron body 1 is used in a self-supporting manner, a burden is placed on the wrist, and usability is poor.

  Therefore, in the present embodiment, the heat insulating material 191 is disposed around the vaporizing chamber 8 so that the number of times of use of the increased steam and the duration of the steam ejection can be increased with a simple configuration. The heat insulating material 191 is stored and held in a recess 192 formed in the vicinity of the vaporizing chamber 8 so as not to jump out of the iron body 1.

  In this case, when the shot button 31B is pushed while the on-off valve 125 opens the nozzle 124, the water dripped from the water outlet 173 of the water flow joint 121 into the vaporizing chamber 8 is vaporized, and all the ejection holes 9, the increased amount of steam is ejected from the hanging surface 41, but by disposing the heat insulating material 191 around the vaporization chamber 8, the heat radiation from the base 4 is suppressed by the heat insulating material 191, and the temperature drop of the base 4 is delayed. Can be made. Therefore, it is possible to increase the number of times the increased steam is used and the duration of steam ejection with a simple configuration in which the heat insulating material 191 is added. Further, in the cordless iron, the number of times of power supply to the iron body 1 is reduced by the amount of the temperature drop of the base 4 being delayed, and an energy saving effect can be obtained.

  Sodium acetate is used for the heat insulating material 191. Sodium acetate is crystallized by applying a stimulus, and the temperature drop in the vaporizing chamber 6 can be delayed by utilizing the heat (solidification heat) generated at that time. As a thing which gives irritation | stimulation to the sodium acetate which comprises the heat insulating material 191, Preferably the bimetal 193 corresponded to a heat sensitive body is used. The bimetal 193 is housed and held in the recess 192 together with the heat insulating material 191, and when the base 4 is heated to a predetermined temperature or more by energization of the heater 3, the bimetal 193 is inverted to give the heat insulating material 191 a stimulating force. it can.

  Thus, in this embodiment, the heat insulating material 191 is made of sodium acetate, so that the weight of the iron body 1 is hardly increased and the number of times the increased steam is used and the duration of the steam ejection can be increased. . Therefore, the burden on the wrist is reduced when the iron body 1 is used, and an easy-to-use iron can be provided. Further, by appropriately selecting the bimetal 193, it becomes possible to give a stimulus to the heat insulating material 191 at a desired temperature.

  In addition, it is also possible to apply the technical features of this embodiment to the irons of the first to fifth embodiments.
