Tighten to 13 and PTC heater Shiko 1
Fix 9 together. The heating plate 24 has a protrusion s25 slightly closer to the front end of the central portion, and a communication hole 26 is formed corresponding to the dogleg groove 16. A protective case 27 was attached to include the protrusion 25 and the communication hole 26 on the heating plate 24, a hole 28 was formed in the upper part corresponding to the protrusion 25, and the lower end was attached inside the protective case 2. The upper end of the coil spring 29 extends upward from the protrusion 25 .

A heat insulating rubber 30 is attached to the upper edge of the nine upright pieces 8 of the assembled hot plate 3, and is pressed against the lower case 5 and screws 7
Fixed by Further, one end of the lead wire 21 is soldered to the terminal pin 31, and the terminal box 32 is fixed to the positioning recess 33 of the lower case 5.

On the other hand, as shown in FIG.
A water absorbent body 38 is inserted into the lower end of the K and is extended, and this water absorbent body 38 is capped with a protective plate 39 having holes. In addition, a protrusion 40 (Fig. 4) is formed on the 11m of the water tank 34, and a KL-shape # (not shown) is formed on the storage cylinder 41 formed on the upper case 4. It is installed by inserting and rotating, and the vertical width of the horizontal groove is increased so that the water tank surface 2 can move in and out. At this time, the waterproof gasket 37 is brought into close contact with the small diameter tube 41a inside the storage tube 41. When the upper case 4 is placed over the case 5 and integrated with the screws 6, a gasket 42 is fitted on the outer surface of the small diameter cylinder 41aO, and the gasket 42 is used to tighten the small diameter cylinder 41a.
a and the agricultural insurance case 27 communicate without water leakage, and the upper end of the coil spring 29 comes into elastic contact with the protective plate 39, and the water supply tank 3
4 is pushed up.

43 is a screw cover and name plate.

The iron stand 44 on which the steam iron is placed is made of synthetic resin, and has the same planar shape as the lower case 5 as shown in FIGS. A protrusion 46 that engages with the locking recess 9 of the hot plate 3 is formed, and when the lower surface of the lower case 5 comes into contact with the upper edge of the iron stand 44, the concave part 9 and the protrusion 46 engage, and the hot plate 3 Cover the second side. At this time, a positioning plate 47 erected at the bottom of the iron stand 44 positions the rear end of the hot plate 3 to facilitate attachment to the iron stand 44.

The iron stand 44 also has spring mounting protrusions 48 and 49 facing each other at predetermined positions on the rear side of the inner surface thereof, and a mounting hole 50 is formed on these opposing surfaces.
Grooves 5] and 52 are formed in the vertical direction. The pair of springs 53 are approximately U-shaped, and the intermediate rod 53sh is bent into a U-shape to form vertical portions 54 at both ends thereof.
b t'iThe tip thereof is bent outward to form a rotating shaft 55, and the mounting hole 50 is closed by the spring action of both ends 53b.
When both ends 53b engage with the horizontal $51, it falls onto the iron stand 44 as shown in FIG. 11, and 1lFl! When the four rods 53b engage with the vertical grooves 52, they stand up as shown in FIG. 10 and are assembled so that they can be raised and lowered.

We will explain how this steam iron works and how to use it. That is, first, the water supply tanks 3 and 4 are removed from the storage cylinder 41, the water supply cylinder 36 is removed from the water supply tank 34, and water is supplied into the water supply tank 34.

-! Next, from the state shown in Fig. 8, the iron holder 44 is pulled to release the projection 46, the spring 53 is erected, and the steam iron is placed on the intermediate bar 53a of the spring 53 (Fig. 1θ). At this time, the dimensions of the hot plate 3#'i are set so as to be positioned on the arcuate edge of the hot plate 3 by the vertical portion 54 of the spring 53, as shown in the image lines P and P' in FIG. It is stably fixed without moving forward, backward, left or right. Next, insert the plug 55 into the terminal bin 31, and power cord (not shown)
The other plug blade is inserted into an outlet (not shown) K to supply current to the PTC heater element 19. This heats the hot plate 3 and the hot plate 24, and when the hot plate 3 reaches an appropriate temperature, it is pressed against a handkerchief, blouse, etc. to iron it. At this time, when the water supply tank 2 is pressed with the index finger Y as shown in FIG.
As a result, the water absorbent body 38 is heated, the water in the water absorbent body 38 is vaporized, and steam is generated from the holes in the protection plate 39. The generated steam flows from the communication hole 26 in the protective case 27 to the groove 16.
The steam enters into the water and is further ejected to the outside from the steam ejection hole 15.

By the way, in the above operation, the temperature of the heating plate 24 is set to, for example, 140°C, the temperature of the heating plate 3 is set to tf-i2o°C,
It is desirable to lower the latter. That is, the temperature required for the heating plate 24 to generate steam is about 135° C. or higher, and when the temperature reaches a high temperature (for example, 160° C. or higher), the temperature increases, so at first it becomes water beads and scatters. Based on the fact that steam is emitted after the heating plate 24 is cooled, that is, there is a time delay before the temperature of the heating plate 24 becomes too low, and the heating plate 3 is
This is because there is no need to make the temperature as high as 4.

With this structure, this steam iron has the following effects. That is, (1) because the heating plate 3 is placed on one side of the heater element 19 and the heating plate 24 is placed on the other side, it is possible to efficiently switch between wet and dry irons, and it can also be used for both wet and dry irons. This makes manufacturing easier.

When the temperature of the heating plate 24 is set higher than that of the heating plate 3, the heating of the heating plate 3 and the heating for generating steam are balanced, allowing efficient ironing.

(3) Since the heater element 19 is a PTC heater element, it can be made smaller. Also, compared to thermostats that control power on and off, heat can be refilled and supplied at all times. In the case of a thermostat, it is difficult to continuously generate steam using a small amount of electricity because it cannot provide sufficient heat when the thermostat is off.

(4) PTC heater element 19't-Since it is sandwiched between the heating plate 3 and the heating plate 24, the structure is simplified.

(5) Since the PTC heater element 19 is located at the center of the hot plate 3, heat is evenly transmitted to the part 4 of the hot plate 3, resulting in a great wrinkle smoothing effect.

(6) $1 on the outer periphery of the steam nozzle formed on the hot plate 3
6 is formed, steam does not flow directly to the steam ejection hole 15 due to the groove 16, and bumping can be prevented.

(7) The power supply to the steam iron main body is provided by a separate cord plug 55 which is detachably connected to the terminal bin 31 of the main body, making it convenient to carry.

As described above, the electric iron of the present invention has the effect of being able to be used both as a wet type and as a dry type, since it has a hot plate serving as an iron base on one side of the heater and a hot plate serving as a steam heat source on the other side. be.
