A connecting body 13 is connected to the heat insulating plate 9 from the inner wall of the handle body 10 so as to hang downward.

  A concave portion 19 is provided at a lower position corresponding to the wall body 13 on the upper surface of the heat insulating plate 9, and the lower end 13 a of the wall body 13 is extended to fit into the concave portion 19. The wall 13 and the recess 19 are long in the width direction of the iron body 1, that is, in a direction substantially orthogonal to the front-rear direction.

  Reference numeral 14 denotes a lead plate connected to the power supply pin 15 of the iron body 1. The lead plate 14 is passed through a through-hole 16 provided as a hole in a part of the heat insulating plate 9 and is placed in the grip portion 11. The temperature control means 17 for controlling the temperature of the surface 6 is connected to the wiring screw 18. The wall body 13 is configured at a position between the connection body 12 and the through-hole 16.

  A rear wall 21 formed long in the width direction of the iron body 1 is disposed on the upper surface of the heat insulating plate 9 between the through hole 16 and the position facing the wall body 13 of the handle body 10 in the front-rear direction. It is extended toward. The height position of the upper end 21 a of the rear wall body 21 is set to be higher than the lower end 13 a of the wall body 13.

  In addition, since the other structure is the same as that of the steam iron demonstrated as a prior art example, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  The operation and action of the steam iron configured as described above will be described below. The basic operation as a steam iron is the same as that well known in the art, and a detailed description thereof will be omitted.

  First, when the water in the water tank 7 is supplied to the vaporizing chamber 4 by operating the steam button 8, steam is generated in the vaporizing chamber 4 heated by the heater 2, and is ejected to the outside through the steam hole 5. Can be ironed.

  At this time, as shown by arrows in FIGS. 1 and 2, a part of the steam ejected from the steam hole 5 enters between the base 3 and the heat insulating plate 9 and enters the handle body 10 through the through hole 16. To do. However, when the steam comes into contact with the wall body 13 provided at the position between the connecting body 12 and the through-hole 16 on the inner wall of the handle body 10, the steam is cooled by the wall body 13 and changed into water droplets, and the water droplets travel along the wall body 13. Since the wall body 13 is arranged so as to be close to the heat insulating plate 9, a condensed water film 20 is formed between the wall body 13 and the heat insulating plate 9, and the steam is connected to the inside of the wall body 13, that is, connected. Since the connection body 12 is not exposed to steam because it does not enter the body 12 side, the strength does not become weak due to deterioration or the like, and a highly safe steam iron can be provided.

  Moreover, since the recessed part 19 was provided in a part of the heat insulation board 9 under the wall body 13 and the wall body 13 was extended so that the lower end 13a might be fitted in the recessed part 19, steam was cooled by the wall body 13 and it became water droplets. The water droplets move downward along the wall 13 and accumulate in the recesses 19, so that a dew condensation film 20 is more easily formed between the wall 13 and the heat insulating plate 9, and the steam is Since the connection body 12 is not exposed to steam because it does not enter the inside of the body 13, that is, the connection body 12 side, the strength does not become weak due to deterioration or the like, and a highly safe steam iron is provided. Can do.

Furthermore, since the wall 13 is extended so that the lower end 13a fits in the recess 19, the dew condensation water film 20 can be strongly held in the recess 19. Condensation water film 20 may be cut or water droplets may move forward and invade connection body 12 in response to acceleration or when ironing body 1 is placed in the middle of ironing. Thus, it is possible to prevent the strength from being weakened and to prevent the water droplets from moving backward and adversely affecting the electrical system of the lead plate 14 and the wiring screw 18.

  Further, the rear wall 21 is located between the through hole 16 and the position facing the wall 13 of the handle body 10 on the upper surface of the heat insulating plate 9, that is, upstream of the flow of steam entering the wall 13. Further, the height of the upper end 21a is set at a position higher than the lower end 13a of the wall body 13, so that the maze effect makes it difficult for steam to enter the connecting body 12 side and the upper end of the rear wall body 21. It is possible to guide the steam that has entered through 21a to come into contact with the wall body 13 with certainty, and the steam can be more reliably formed into water droplets.

  In the present embodiment, the wall body 13 is integrated with the handle body 10, but as shown in FIG. 3, the wall body 13 and the handle body 10 are formed of separate members, and the wall body 13 is made of metal. Then, the steam is more easily cooled and changed into water droplets than the resin or the like by the wall body 13, and a condensed water film 20 is more easily formed between the wall body 13 and the heat insulating plate 9. Since it is harder to enter the inside than the body 13 and the connection body 12 is not exposed to steam, the strength does not become weak due to deterioration or the like, and a steam iron with higher safety can be provided.

  In this embodiment, both the wall body 13 and the rear wall body 21 are formed long in the width direction of the iron body 1. However, even if the wall body 13 and the rear wall body 21 are limited to the front portion corresponding to the through-hole 16, Regardless of the difference, the effects of the present invention can be obtained.

  As described above, the steam iron according to the present invention forms a condensed water film between the handle body and the heat insulating plate even when steam enters the iron body, so that the fastening portion is deteriorated and weakened. Therefore, it is possible to provide a highly safe steam iron, which can be widely applied to household and commercial steam irons.
