Description

  The present invention relates to a steam iron having a steam jetting function capable of pressing while spraying steam on clothes or the like, and in particular, an iron body having a nozzle for dropping water on an iron base to generate steam. The present invention relates to a structure capable of smoothly supplying water to the base and stably ejecting steam.

  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 steam is used to spout steam onto clothes, etc., if the water supplied from the iron tank to the iron base through the nozzle is not dripped smoothly, steam can be generated successfully. Absent.

  FIG. 5 is a plan view of a conventional steam iron, and FIG. 6 is a side sectional view taken along line YY of FIG.

  Conventionally, this type of iron is configured as shown in FIGS. That is, the vaporizing chamber 3 is formed in the iron base 2 having the heater 1, and this vaporizing chamber is covered with the lid 4. The steam generated in the vaporizing chamber 3 is ejected to the outside through the steam passage 6 through the steam passage 5.

  The tank 9 is detachably provided above the iron base cover 8 in the iron body B. When the tank 9 is attached to the iron body B, the nozzle 10 provided at the bottom of the tank 9 is connected to the elastic cylindrical packing 7 and the outflow guide member. Are connected by a water supply channel 15. And the water put into the tank 9 from the water inlet 11 is supplied to the vaporization chamber 3 through the hole 16 of the elastic cylindrical packing 7 through the water supply path 15 from the nozzle 10. Further, the nozzle 10 is opened and closed by the operation of an open / close lever 13 driven by the steam button 12, and the supply of water to the vaporizing chamber 3 is controlled.

  The elastic cylindrical packing 7 is made of a heat-resistant and heat-insulating material such as silicon rubber, and is attached between the lid 4 of the vaporizing chamber 3 covering the upper surface of the iron base 2 and the iron base cover 8. The coil spring 14 is inserted between the lower surface of the upper end flange and the bottom surface of the vaporizing chamber 3 and fixed so as to be biased upward.

In such a conventional steam iron, the elastic cylindrical packing 7 is in pressure contact with the opening of the water supply channel 15 when the tank 9 is mounted for tight coupling between the removable tank 9 and the vaporizing chamber 3. Therefore, the elastic cylindrical packing 7 is deteriorated and deformed by long-term use. Therefore, in order to compensate for the fact that the elastic force is reduced due to such deformation and the close coupling becomes difficult and the coupling with the opening of the water supply passage 15 of the elastic cylindrical packing 7 is ensured, the elastic cylindrical packing is used. A coil spring 14 for urging 7 toward the tank 9 was provided and pressed against the iron base cover 8.
Japanese Patent No. 3125583 (FIG. 4, paragraphs [0005] to [0010])

  And in the conventional steam iron, the water droplet dripped from the nozzle 10 hangs down spherically by the surface tension in the hole 16 of the elastic cylindrical packing 7, and is dripped by the balance of the water pressure on the water supply channel 15 side and the vapor pressure of the vaporizing chamber 3. However, in such a structure, when the internal pressure of the vaporizing chamber 3 is increased by heating, water droplets from the holes 16 of the elastic cylindrical packing 7 are not accurately dropped. The hole 16 of the elastic cylindrical packing 7 leading to the water supply passage 15 is about 1 mm. However, even if the nozzle 10 is fully opened, it becomes difficult for water to come out, and water does not drip. Accordingly, although the external display of the iron is the steam display, the steam is not ejected, and the function is different from the display.

  Further, since the lower end of the coil spring 14 is supported by the bottom surface 3a of the vaporizing chamber 3 adjacent to the heater 1, the heat of the iron base 2 is transmitted to the elastic cylindrical packing 7 through the coil spring 14 and heated. As a result, there is a problem that deterioration of the elastic cylindrical packing 7 is promoted by this heat.

  Further, since the coil spring 14 is disposed in the vaporizing chamber 3, the elastic characteristics are changed by adhering evaporation residue such as water scale and hardening, so that the sealing action is reduced, and the tank 9 and There is a problem that it is difficult to keep the bonded state of the vaporizing chamber 3 constant over a long period of time.

  Furthermore, since the elastic cylindrical packing 7 is configured to be pressed and fixed to the iron base cover 8 in an unstable state supported by the coil spring 14, the elastic cylindrical packing 7 installed on the lid 4 is used. When the iron base cover 8 is covered and attached from above, care must be taken so that the upward biasing force of the coil spring 14 acts correctly on the elastic cylindrical packing 7.

  As a result of various studies to solve the above problems, the inventors of the present application have made it possible to smoothly drop water droplets dropped from the nozzles and pushed out of the holes of the elastic cylindrical packing through the water supply passages into the vaporization chamber. In addition, it has been found that by providing a guide means for guiding the dripping water, which connects the elastic cylindrical packing and the bottom of the vaporizing chamber, the steam button can quickly guide the water droplet to the bottom of the vaporizing chamber as intended, and vaporize it. The steam iron according to the present invention has been completed.

  That is, the present invention has been made to solve the above-described problems, and water droplets from the nozzles can be accurately dropped into the vaporizing chamber to stably generate steam, which is compatible with the function display of the iron.
