DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron used for removing wrinkles of clothes and the like in ordinary households.

[0002]

2. Description of the Related Art Conventionally, this type of iron has the configuration shown in FIG.

Hereinafter, description will be made with reference to FIG. First, reference numeral 1 denotes an iron body, which is provided with a water tank 2 for storing detachable water.
Opening / closing device 4 for opening / closing a passage for supplying the water inside the water passage 3
have.

[0004] The opening and closing device 4 includes a steam button 5 formed on the upper part of the water tank 2 so as to be movable up and down, an opening and closing stick 6 which moves up and down by operating the steam button 5 and has a latch mechanism, and an opening and closing stick 6. And a button spring 7 for urging the steam button 5 upward. Further, the lower end of the opening / closing rod 6 has a hemispherical shape, and can be in contact with the upper end of the water channel 3 to close the water path to the water channel 3. Waterway 3
Is provided above the vaporizing chamber 8, and the water in the water tank 2 is dropped into the vaporizing chamber 8 through the water passage 3 from a dripping hole 9 provided at the lower end. On the surface to be ironed, a steam hole 10 through which steam from the vaporizing chamber 8 gushes is formed.

[0005] Reference numeral 11 denotes a first base made of aluminum in which the vaporization chamber 8 and the heater 12 are provided. Above the first base 11, a temperature is formed by a thermistor for detecting the temperature of the first base 11. A detection sensor 13 is provided, and a change in resistance value due to the temperature of the temperature detection sensor 13 is transmitted to the control circuit 14 so that the control circuit 1
4 controls the calorific value of the heater 12 to control it to an appropriate temperature.

Reference numeral 15 denotes a heat resistance layer having a heat conductive action in contact with the lower portion of the first base 11, and 16 denotes a heat resistance layer.
A second base made of aluminum having an ironing surface in contact with the lower side. The heat resistance layer 15 is made of silicon rubber having a lower thermal conductivity than the second base 16 made of aluminum and having heat resistance.

Reference numeral 17 denotes a first steam path opened below the vaporization chamber 8 of the first base 11, and reference numeral 18 denotes a heat conduction steam path opened to the heat resistance layer 15 immediately below the first steam path. Has a steam hole 10 formed in a second base 16.

The operation of the above configuration will be described. First, when the operator turns on the switch of the control circuit 14, the heater 12 is energized. The heat generated by the heater 12 directly heats the first base 11. However, since the heat resistance layer 15 is in contact with the first base 11 and the second base 16 is in contact with the heat resistance layer 15, the heat of the first base 11 is
The second base 16 is also heated at the same time. After a while, the temperature detection sensor 13 in contact with the first base 11 detects that the first base 11 has reached a predetermined temperature, and the control circuit 14 turns off the heat of the heater 12.
When the temperature decreases, the heater 12 starts to generate heat by the temperature detection sensor 13, and the temperature is adjusted within a certain temperature range. However, a certain temperature difference occurs between the first base 11 which is directly heated by the heater 12 and the second base 16 which releases heat from the ironing surface. This is because there is a constant equilibrium between the first base 11 which is the heat supply side and the second base 16 which is the heat release side because the heat resistance layer 15 having a low thermal conductivity is interposed therebetween. Is caused.

That is, although the temperature of the ironing surface is appropriate for the fibers, the temperature of the first base 11 can be made higher than that, and a large amount of heat can be stored.

Next, the steam will be described. Similar to the conventional example, when the steam button 5 is pressed against the urging force of the button spring 7 to lower the piston 19 and release the latch mechanism, the opening / closing rod 6 rises and the water channel 3 Passage is released. Then, the water in the water tank 2 is dropped into the vaporization chamber 8 from the drip hole 9 through the water channel 3 due to the head difference. The dropped water removes heat from the first base 11 to be vaporized and becomes steam, and is ejected from the steam hole 10 through the first steam path 17 through the heat conduction steam path 18.

As described above, since the amount of stored heat is increasing,
Even when the temperature of the ironing surface decreases, the high temperature of the first base 11 replenishes heat, so that steam can be used continuously for a longer time.

[0012]

However, in such a conventional structure, the steam temperature rises to near the temperature of the first base, so that the temperature becomes higher than the temperature suitable for the fiber. There was a problem that bad effects such as burning were caused.

In view of the above, an object of the present invention is to solve the above-mentioned conventional problems and to provide an iron capable of lowering the temperature of steam to around a temperature suitable for the fiber.

[0014]

In order to solve the above-mentioned problems, an iron according to the present invention comprises a first base for inscribing heat by inscribing a heater, and a vaporization chamber provided on the first base. , Consisting of three layers, a second base having an ironed surface and a heat resistance layer sandwiched therebetween, and a steam retention layer in contact with the second base, which is vaporized by the first base. The steam thus generated is temporarily retained in the steam retaining layer, a part of the heat of the steam is radiated to the second base, and then the steam is jetted from the second base.

[0015]
