Description

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 been configured as shown in FIG. Hereinafter, the configuration will be described.

As shown in FIG. 1, an iron body 1 includes a base member 3 having a vaporizing chamber 2 formed therein, a heater 4 for heating the base member 3, and a hook member 6 fixed to the base member 3 with screws 5. have. The steam button 7
The operation is performed when ironing using steam. By operating the steam button 7, water in the water tank 8 is dropped into the vaporization chamber 2 to generate steam.

In the above configuration, a control circuit (not shown)
Is turned on, the power supply to the heater 4 is started, and the heat generated by the heater 4 heats the base member 3. When the temperature of the base member 3 reaches a predetermined temperature, the control circuit stops energizing the heater 4. In this state, since the base member 3 releases heat even when ironing is started or left naturally, when the temperature decreases, the heater 3 is energized again to control the temperature of the base member 3 to a predetermined temperature.

When ironing using steam, when the steam button 7 is operated after the temperature of the base member 3 reaches a predetermined temperature, the water in the water tank 8 drops into the vaporization chamber 2, The dropped water removes heat from the base member 3 and evaporates, and is spouted as steam.

[0006]

However, in such a conventional configuration, in the case of a cordless iron, the heater 4 is not energized when ironing is performed, so that when steam is used, it drops into the vaporization chamber 2. Since the water removes heat from the base member 3 and rapidly lowers the temperature of the base member 3, the wrinkles of the garment are less likely to elongate, and the time during which steam can be ejected is reduced.

Therefore, when many clothes are ironed at once or when a large amount of steam is generated and used, the temperature of the base member 3 immediately drops, and the heater 4 is energized. While the base member 3 is heated to a predetermined temperature, ironing must be stopped, which causes a problem that the work efficiency is low.

On the other hand, in a cordless iron, the duration during which steam can be jetted is determined by the temperature of the base member 3. That is, if the temperature of the base member 3 is set high, the duration of steam can be prolonged. However, in the conventional configuration, since the hook member 6 is fixed to the base member 3 by the screw 5, the temperature of the base member 3 and the temperature of the hook member 6 are substantially the same, and the hook member 6
It is necessary to set the temperature of the base member 3 to an appropriate temperature depending on the clothing, and there is a limit in raising the temperature of the base member 3. For this reason, in a cordless iron, there was a problem that the duration of steam could not be lengthened and the usability was poor.

[0021]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) As shown in FIG. 1, an iron body 9 includes a base member 11 having a vaporizing chamber 10 formed thereon, a hooking surface member 12 coupled to the lower surface of the base member 11, and a base member 11. A heater 13 for heating is provided, and a steam hole 14 through which steam from the vaporization chamber 10 is blown is opened in the hanging surface member 12. A water tank 15 for storing water is arranged above the base member 11, and a nozzle 17 for supplying water in the water tank 15 to the vaporization chamber 10 by an opening / closing device 16.
Is opened and closed.

The opening / closing device 16 has a steam button 18 formed on the upper part of the water tank 15 so as to be movable up and down, and an opening / closing rod 19 which moves up and down by operation of the steam button 18. Further, the lower end of the opening / closing rod 19 has a hemispherical shape, and is configured to be in contact with and close to the upper end of the nozzle 17. The nozzle 17 is provided above the vaporization chamber 10, and the water in the water tank 15 is dropped into the vaporization chamber 10 from the drip unit 20 via the nozzle 17.

A temperature detecting sensor 21 composed of a thermistor for detecting the temperature of the base member 11 is provided above the base member 11.
The control circuit (not shown) inputs a change in resistance value due to the temperature of No. 1 and controls the heat generation amount of the heater 13 by the control circuit to control the heater 13 to a predetermined temperature.

The base member 11 is made of aluminum or an aluminum alloy, and as shown in FIG. 2, a contact surface 22 made of aluminum is formed on a rough surface by a blasting method such as sand blasting. The contact surface 23 of the surface member 12 with the base member 11 is also formed into a rough surface by the same blast method, and when the base member 11 and the hanging surface member 12 are brought into contact, an air layer 24 is formed. I have.

The operation of the above configuration will be described. First, when the control circuit is turned on, the power supply to the heater 13 is started, and the heat generated by the heater 13 heats the base member 11. Since the hanging member 12 is connected to the base member 11 via the air layer 24, the base member 11 is heated, so that the hanging member 12 is simultaneously heated via the air layer 24.

When the temperature detection sensor 21 in contact with the base member 11 detects that the temperature of the base member 11 has reached a predetermined temperature, the control circuit stops energizing the heater 13. When the temperature of the base member 11 decreases, the power supply to the heater 13 is resumed, and
Is controlled to a predetermined temperature.

At this time, as the temperature of the hanging surface member 12,
For example, assuming that the temperature of 200 degrees Celsius is appropriate for the fiber, the air layer 24 is interposed between the base member 11 and the hanging member 12, so that the distance between the base member 11 and the hanging member 12 is low. Causes a temperature difference. For this reason, the hanging surface member 1
If the temperature of 2 is constant, the temperature of the base member 11 can be increased by the temperature difference, so that more heat can be stored than before.

Therefore, the heat storage amount can be increased without increasing the weight of the iron body 9. As a result, even if many clothes are ironed at once, the temperature drop of the entire base can be suppressed to a small extent, so that wrinkles can be surely extended and power is temporarily supplied to heat the iron on the way. This eliminates the need to perform ironing, which facilitates ironing work and improves usability.

FIG. 3 shows an experimental result of how the thermal conductivity changes when the roughness of the rough surface of at least one contact surface of the base member 11 or the hook member 12 is changed. Things. In this experiment, when the roughness was changed, the temperature difference between the surface temperatures of the base member 11 and the hook member 12 was measured. As a result, the roughness of the rough surface
When (ten-point average roughness) = 10 μm or more, it can be said that the temperature difference between the base member 11 and the hooking surface member 12 increases rapidly.

Therefore, the roughness of at least one of the surfaces where the base member 11 and the hooking surface member 12 are in contact with each other is reduced to 10
By setting the thickness to at least μm, the temperature of the base member 11 can be increased by the temperature difference, and the heat storage amount can be increased. As a result, even if many clothes are ironed at once, the temperature drop of the entire base is reduced. Can be suppressed,
Wrinkling can be reliably performed, and there is no need to temporarily supply power to heat the iron in the middle, so that ironing work is facilitated and usability can be improved.

Next, the operation as a steam iron will be described. When the steam button 18 is pressed to release the latch mechanism, the opening / closing rod 19 is raised and the nozzle 17 is opened. For this reason, the water in the water tank 15 is dripped into the vaporization chamber 10 from the dripping part 20 through the nozzle 17. The dropped water removes heat from the base member 11, evaporates and becomes steam, and squirts from the steam hole 14.

At this time, the base member 11 and the hanging surface member 1
Since the air layer 24 is interposed between the base member 11 and the base member 11, a temperature difference occurs between the base member 11 and the hanging member 12. If the temperature of the hanging member 12 is kept constant, the temperature of the base member 11 becomes lower. High temperature can be achieved by the difference. Therefore, the base member 11
The time required for the temperature to drop to a temperature at which steam does not occur becomes longer, and the steam duration can be lengthened, so that wrinkles can be surely stretched and the iron is temporarily heated during heating. There is no need to supply power, ironing work becomes easy, and usability can be improved.

In the case of a steam iron, the roughness of at least one of the surfaces where the base member 11 and the hanging surface member 12 are in contact with each other is set to 10 μm or more.
As a result of raising the temperature of the base member 11 by the temperature difference,
The time required for the temperature of the base member 11 to drop to a temperature at which steam is not generated is prolonged, wrinkles can be reliably increased, and there is no need to temporarily supply power to heat the iron on the way, and ironing is performed. Work becomes easy, and usability can be improved.

In this embodiment, both the base member 11 and the hanging member 12 have rough contact surfaces formed by sandblasting.
Either one of the two may be formed on a rough surface. In addition, although it is formed on a rough surface by sand blasting, it is formed on a rough surface by a method other than the blast method, for example, a method of forming irregularities during molding to make a rough surface, mechanical processing such as cutting or pressing. Is also good.

In this embodiment, the cordless iron has been described. However, the same effect can be obtained even with a cord, and the effect is exhibited when a large amount of steam is used or when large clothes are ironed at once. Is what you do. Furthermore, the weight of the iron body 9 can be reduced by the amount corresponding to the increase in the amount of heat storage, and the amount of heat storage can be made equal to that of the conventional case. In this case, there is also an effect that the operation becomes easy as the iron becomes lighter.

(Embodiment 2) As shown in FIG. 4, the base member 25 is made of aluminum, and the base member 25 is made of a material having a lower thermal conductivity than the base member 25, such as ceramic, iron, or stainless steel. The contact surface 27 of the base member 25 with the hooking surface member 26 is formed rough by sandblasting (blasting), and
The contact surface 28 with the base member 25 is also roughened by sand blasting (blasting), and when the base member 25 and the hanging surface member 26 are brought into contact, the air layer 2
9 are formed. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described. The base member 25 is heated by the heat generated by the heater 13. Since the hanging member 26 is coupled to the base member 25 via the air layer 29, the heating of the base member 25 causes the hanging member 26 to be simultaneously heated via the air layer 29.

At this time, as the temperature of the hanging surface member 26,
For example, assuming that 200 degrees Celsius is an appropriate temperature for the fiber, the hanging member 26 is made of a material having a lower thermal conductivity than the base member 25 formed of aluminum such as ceramic, iron, and stainless steel. When it is difficult to conduct heat between the base member 25 and the hanging surface member 26, a temperature difference occurs. If the temperature of the hanging surface member 26 is kept constant, the temperature of the base member 25 can be increased by the temperature difference. it can.

Further, the base member 25 and the hanging surface member 26
, An air layer 29 is interposed therebetween, so that a temperature difference occurs between the base member 25 and the hanging surface member 26. If the temperature of the hanging surface member 26 is kept constant, the temperature of the base member 25 can be increased by the temperature difference, so that more heat can be stored than before.

Therefore, the heat storage amount can be increased without increasing the weight of the iron body 9. As a result, even if a large number of clothes are ironed at once, the temperature of the entire base can be kept low, so that the wrinkles can be surely stretched, and power is supplied temporarily to heat the iron on the way. There is no need to do so, ironing work becomes easier, and usability can be improved.

Also, when used as a steam iron, a temperature difference occurs between the base member 25 and the hanging surface member 26. If the temperature of the hanging surface member 26 is constant, the temperature of the base member 25 is reduced by the temperature difference. Since the temperature can be raised to a high temperature, the time required for the temperature of the base member 25 to drop to a temperature at which steam is not generated is prolonged, wrinkling can be reliably performed, and it is necessary to temporarily supply power to heat the iron on the way. And ironing work becomes easier, and usability can be improved.

In this embodiment, the base member 25 is made of aluminum, and the hanging surface member 26 is made of ceramic.
It is made of a material having a lower thermal conductivity than the base member 25 such as iron and stainless steel.
Although the surface 28 is formed as a rough surface, the contact surfaces 27 and 28 need not be formed as a rough surface.

Further, even when the contact surfaces 27 and 28 are formed as rough surfaces, one of the contact surfaces 27 and 28 may be formed as a rough surface.

(Embodiment 3) As shown in FIG. 5, the base member 30 is made of aluminum, and the contact surface 32 with the hanging member 31 made of aluminum is roughened by sand blasting (blasting method). The contact surface 33 of the hanging surface member 31 with the base member 30 is also formed in a rough surface by sandblasting (blasting) so that the air layer 34 is formed when the base member 30 and the hanging surface member 31 are brought into contact. I have to. The hanging surface member 31 has a fluororesin-containing film 35 formed on a surface including a contact surface with the base member 30 and an ironing surface. Other configurations are the same as those in the first embodiment.

The operation of the above configuration will be described. The base member 30 is heated by the heat generated by the heater 13. The base member 30 includes an air layer 34 and a fluorine resin-containing film 35.
The base member 30 is heated by the heating, so that the base member 30 is also heated via the air layer 34 and the fluororesin-containing film 35 at the same time.

At this time, as the temperature of the hanging surface member 31,
For example, if 200 degrees Celsius is an appropriate temperature for the fiber, an air layer 34 and a fluororesin-containing coating 35 are interposed between the base member 30 and the hanging surface member 31,
A temperature difference occurs between the base member 30 and the hanging surface member 31. Therefore, assuming that the temperature of the hanging surface member 31 is constant,
The temperature of the base member 30 can be raised by the temperature difference.

Therefore, even if a large number of clothes are ironed at once, the temperature of the entire base can be slowed down, so that the wrinkles can be surely spread and the iron must be heated halfway. There is no need to temporarily supply power, ironing work becomes easier, and usability can be improved.

Also, when used as a steam iron, a temperature difference occurs between the base member 30 and the hanging surface member 31, and if the temperature of the hanging surface member 31 is kept constant, the temperature of the base member 30 is reduced by the temperature difference. Since the temperature can be raised to a high temperature, the time required for the temperature of the base member 30 to decrease to a temperature at which steam is not generated is prolonged, wrinkling can be reliably performed, and it is necessary to temporarily supply power to heat the iron on the way. And ironing work becomes easier, and usability can be improved.

In this embodiment, the base member 30 and the hanging member 31 are both made of aluminum. However, the hanging member 31 has a lower thermal conductivity than the base member 30 made of ceramic, iron, stainless steel or the like. Although the contact surfaces 32 and 33 may be formed of a material, and the respective contact surfaces 32 and 33 are formed as rough surfaces, the contact surfaces 32 and 33 may not be formed as rough surfaces.

Further, even when the contact surfaces 32 and 33 are formed as rough surfaces, one of the contact surfaces 32 and 33 may be formed as a rough surface.

In this embodiment, the hanging surface member 31 is
Although the fluororesin-containing film 35 is formed on the surface including the contact surface 33 with the base member 30 and the ironing surface, the fluororesin-containing film 3 is formed only on the contact surface 33 with the base member 30.
5 may be formed.
