Description

  The present invention relates to a steam iron having a steam blowing function that can be pressed while spraying steam on clothes, etc., and can be used to spread steam widely and deeply in a cloth, suppressing unevenness and obtaining a sure finish. Is to provide.

  When ironing clothes or the like, there is a so-called steam iron having a steam function so that it can be efficiently pressed by spraying steam in order to make it easy to stretch wrinkles and adjust the shape. When steam is used to spout steam onto clothing, etc., the water supplied to the vaporizing base from the iron tank through the nozzle becomes steam, and this steam is the steam injection hole on the bottom of the iron base. If it is not supplied so that the fibers such as clothes are sufficiently passed through, the finishing of the iron will not be successful.

  In particular, due to natural material orientation, many clothing using natural fibers such as cotton and hemp have been seen recently, but these fibers are prone to wrinkles and are difficult to remove. When applying sewage, the water supply to clothing is increased by steam spraying to increase the efficiency of wrinkle stretching. However, simply increasing the amount of water supplied requires finishing so as not to leave the increased amount of water, resulting in increased labor. In addition, if the temperature of the vaporizing chamber is set high in order to stretch wrinkles, problems such as the steam ejection being hindered, the temperature becoming higher than the temperature suitable for the fiber, and the fiber being scorched will occur.

  A conventional iron of this type disclosed in Patent Document 1 has a configuration as shown in FIG.

  That is, FIG. 6 includes a first base 520 having a heater 521, a second base 523 having an ironing surface and a vaporization chamber, and a water tank 533 for storing water. A steam iron in which an air layer 528 is formed between two bases 523 is disclosed. With such a configuration, the first base 520 is heated by the heater 521, but the air layer 528 serving as a heat resistance layer is sandwiched between the first base 520 and the second base 523. A temperature difference is generated between the first base 520 that is the heat supply side and the second base 523 that is the heat receiver and the heat dissipation side. And the temperature of a 1st base can be set high by the part of this temperature difference, and heat storage amount can be increased. When the opening / closing device 535 is opened, the water in the water tank 533 is dropped into the vaporization chamber 525 through the water channel 534. The dropped water is vaporized and becomes steam, and passes above the circumferential rib 526 and is ejected from the steam ejection hole 527 to the outside. Since the temperature of the vaporizing chamber 525 can be controlled to be low, the hydrophilicity of the vaporizing chamber can be secured, and smooth vaporization can be promoted.

  Moreover, what was disclosed by the following patent document 2 has a structure as shown in FIG.

  The steam iron includes a first base 620 for storing heat by inscribed heater 612, a vaporizing chamber 608 provided in the first base 620, a second base 616 having an ironing surface, The heat resistance layer 625 is configured as a steam retention layer 623 in contact with the second base 616, and the steam vaporized in the first base 620 is converted into the steam retention layer 623. The second base 616 is configured to temporarily stagnate at 623 and release a part of the steam heat to the second base 616 and then to be ejected from the second base 616.

  That is, a steam staying layer 623 is provided between the first base and the second base, and the steam generated in the vaporization chamber once stays in the steam staying layer, and then from the steam hole 610 provided in the second base. Due to the jetting configuration, part of the heat energy of the steam is radiated to the second base 616. If the temperature of the steam heated by the first base, which acts as a high-temperature heat storage material, is too high for the fiber, it will have a bad effect such as scorching the fiber, but a part of the heat energy of the steam will be By transferring heat to the base, the temperature of the steam itself can be lowered, and as a result, steam having an appropriate temperature can be provided to the fiber.

  By the way, in these steam irons, it is possible to provide steam at an appropriate temperature to the fibers, but the steam injection is made from a jet opening opened on the ironing surface, and the jet outlet is a horseshoe-shaped groove provided in the base. In this respect, the state of steam jetting does not change, and the finish of ironing is not particularly improved. The steam was limited to the vicinity of the spout, and it was possible to spread the steam widely and deeply in the fabric.
