DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless iron for reducing wrinkles of clothes and the like.

[0002]

2. Description of the Related Art Conventionally, this type of cordless iron has a configuration as shown in FIGS. Hereinafter, the configuration will be described. As shown in FIG.
Is buried in the base 2 and the vaporization chamber 3
And a water tank 4 is arranged above the base 2.

The water in the water tank 4 passes through a hole 6 provided in a heat insulating plate 5 covering the upper surface of the base 2, passes through a water guide 7 disposed between the heat insulating plate 5 and the base 2, and becomes a vaporization chamber. 3. A nozzle 9 which is manually opened and closed by a valve device 8 is provided at the bottom of the water tank 4, and is connected to the water guide 7 by a rubber cover 10 to form a water passage. In the heater 1, reference numeral 1a denotes a non-heating element that does not include a heating element.

On the other hand, the water guide 7 is provided with a thermally responsive valve device 12 which is opened and closed by a thermally responsive member 11 provided on the base 2, and when the temperature of the vaporization chamber 3 is lower than the appropriate temperature for vaporizing water. In addition, the water guide 7 is shut off by the thermally responsive valve device 12, and the water in the water tank 4 is not supplied to the vaporization chamber 3 even when the valve device 8 is manually opened.

The thermal fuse 13 shuts off power supply to the heater 1 when the base 2 is abnormally heated. Thermistor 14 transmits temperature information of base 2 to control means 15. The vaporization chamber lid 16 covers the upper part of the vaporization chamber 3. The handle 17 forms the grip of the iron body and also forms the upper part of the water tank 4. The stand 18 mounts the iron body and supplies power.

[0006]

However, in such a conventional cordless iron configuration, when the iron body is detached from the stand 18 for ironing,
The base 2 and the vaporization chamber 3 are cooled by the heat of vaporization necessary for heat release and steam generation. As a result, when the temperature drops to a predetermined temperature, the thermally responsive member 11 operates and the thermally responsive valve device 1
2, the water guide 7 is shut off, and the steam is not generated after a certain time has passed.

However, in the cordless iron having the conventional configuration, it is conceivable to increase the heat capacity of the base 2, that is, increase the weight of the base 2 in order to increase the duration of steam generation after detachment. ,
Since the weight of the iron body increases, there is a problem that the usability is deteriorated for the user.

Conventionally, except when actually ironing, for example, a state in which the iron body is floated from a cloth to move the iron body, or before the iron body is detached from the stand 18 and ironed. When the steam is not actually required, for example, from the time of ironing to the time when the iron body is placed on the stand 18, since the steam is generated, the base 2 is unnecessarily used. Has been cooled, and as a result, there has been a problem that the steam duration is short.

[0009] The present invention solves the above-mentioned problems, and prevents unnecessary cooling of the base by generating steam only when the iron body is actually used, thereby increasing the weight of the iron body more than necessary. The purpose is to extend the duration of the steam that can be squirted without causing the steam to squirt.

[0010]

In order to achieve the above object, the present invention provides a base heated by a heater, a vaporization chamber provided on the base, a water tank disposed above the base, A water supply channel for supplying water from the water tank to the vaporization chamber, a handle forming a grip portion of the iron, horizontal detection means for detecting the horizontal state of the base hanging surface, and an output of the horizontal detection means from the water tank to the vaporization chamber A shut-off device for shutting off supply of water to the iron, a main body having a power source for operating the horizontal detection means and the shut-off device, and a stand for mounting the iron main body. When inclined from a state by a predetermined angle or more, the shutoff device is operated by the output from the horizontal detection means to stop the supply of water to the vaporization chamber. It is one of means for solving the problems.

[0011] Further, a base heated by a heater, a vaporization chamber provided in the base, a water tank disposed above the base, and a water conduit for supplying water from the water tank to the vaporization chamber. A handle forming an iron grip portion, contact detection means for detecting the presence or absence of contact of the base surface with a cloth or the like, and supply of water from the water tank to the vaporization chamber by an output of the contact detection means.

This is a second problem solving means.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the first aspect of the present invention, the present invention is directed to a vaporization chamber when a base surface of an iron body is in a horizontal state or within a range of a predetermined inclination angle. Will be supplied with water. That is,
When the base surface of the iron body is inclined by a predetermined angle or more, water is not supplied to the vaporization chamber, so that unnecessary cooling of the base can be prevented, and the duration during which steam can be jetted can be increased.

Further, according to the second means for solving the above problems, when the base surface of the iron body is in contact with an object such as cloth, water is supplied into the vaporizing chamber, so that the base becomes unnecessary. Cooling can be prevented, and the duration during which steam can be ejected can be increased.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted. As shown in the figure,
The base 19 is heated by the heater 1, and the thickness of the base 19 below the heater 1 is gradually reduced so that the frontmost portion is thicker at A and the rearmost portion is B. That is, the heater 1 is included in the base 19 so as to have a relationship of A> B.

A heating wire (heating element portion) 20 is wound inside the heater 1, and a terminal of the heating wire 20 is a non-heating element within a range in which the heater 1 is included in the vaporization chamber 3. It is connected to a terminal rod 21. That is, the heating wire 20 of the heater 1 is provided only at a position located on the bottom surface of the vaporization chamber 3. The cylindrical portion 22 forms an outer shell of the heater 1, and the insulating portion 23 insulates and holds the space between the cylindrical portion 22 and the terminal rod 21. 24 is an insulator.

The control circuit 26 controls energization of the heater 1 included in the base 19 in a state where the iron body is placed on a stand (not shown). Thermistor 14
Transmits the temperature information of the base 19 to the control circuit 26.
The horizontal detecting means 28 detects the horizontal state of the iron main body. The shutoff device 29 controls the flow of water from the water tank 4 to the vaporization chamber 3 in cooperation with the horizontal detection means 28.

When the iron body is inclined from a predetermined angle, the shut-off device 29 is output from the horizontal detecting means 28.
Is operated to stop the supply of water to the vaporization chamber 3. The power supply circuit 30 connects the iron body to the stand 1
Even in the state in which the control unit 26 is separated from the control unit 8, the power supply for operation is supplied to the control circuit 26, the horizontal detection unit 28, the shutoff device 29, and the like.

The operation of the above configuration will be described. First, when the control circuit 26 is operated with the iron main body mounted on the stand 18, the heater 1 is energized and the base 19 reaches a predetermined temperature. A signal from the thermistor 14 attached to the base 19 is transmitted to the control circuit 26, and the power supply to the heater 1 is stopped by an operation of a relay or the like.

At this time, water for generating steam is stored in a water tank 4 provided inside the iron main body. When a predetermined amount of water is supplied, a water level line is set to a hole provided in the heat insulating plate 5. Since it is located below the section 6, water does not drip into the vaporization chamber 3 regardless of the operation of the nozzle 9 or the thermally responsive valve device 12 which is manually opened and closed.

Next, when the iron body is detached from the stand 18 and the iron body is leveled in order to perform ironing, the water level line in the water tank 4 is higher than the hole 6 of the heat insulating plate 5. The water in the water tank 4 passes through the water guide 7 and is dropped into the vaporization chamber 3, where it is vaporized and ejected as steam.

Since the heater 1 is inclined with respect to the bottom surface of the base 19 so as to have a relation of A> B, the heat capacity of the vaporization chamber 3 becomes large. The rate of temperature decrease is slow.

As described above, according to the present embodiment, during the operation of detaching from the stand 18 for supplying power to the iron body at the time of use and repeatedly placing the iron, the base 19 is detached and steam is generated.
Is cooled, and the thermally responsive valve device 12 is
Operates, and the time during which the water guide 7 is cut off is prolonged.

At the time of mounting, the base 1 near the vaporization chamber 3 is mounted.
Since the heat is heated around the center 9, the heat capacity can be sufficiently recovered even in a short mounting time, so that the heat capacity of the base 19 can be effectively increased without increasing the weight of the iron body more than necessary, and steam is generated. The temperature difference between the front and rear portions of the base 19 caused by the heat of vaporization at the time can be reduced. Therefore, the steam duration can be increased by effectively utilizing the heat capacity of the base 19.

When the iron body is placed on the stand 18, the heater 1 is energized to heat the base 19, but the heating wire 20, which is the heating element of the heater 1, is entirely contained in the vaporization chamber 3. Therefore, all of the supplied electric power contributes to the temperature rise around the vaporization chamber 3 except for the loss, and the temperature rise speed of the base 19 around the vaporization chamber 3 cooled at the time of steam generation is increased. Will do.

As described above, according to the present embodiment, since the heating wire 20 of the heater 1 is provided only at the position located on the bottom surface of the vaporization chamber 3, the heating wire 20 is placed on the stand 18 and the base 19 is supplied during power supply.
The temperature difference between the front and rear portions of the base 19 caused by the heat of vaporization when steam is generated can be reduced.

After the iron body is placed on the stand 18 and the base 19 has reached a predetermined temperature, the iron body is detached from the stand 18 and an object such as cloth is ironed on the base 19. When the bottom surface is in a horizontal state, the horizontal detecting means 28 is in a state of not outputting a signal. During this time, the control circuit 26 continues to output a signal to the shutoff device 29 so as to open the water channel.

When the operation of returning the iron body to the stand 18 is performed, or when the iron body is inclined at a predetermined angle or more in order to change the ironing position, the horizontal detecting means 28 is controlled by the control circuit. 26, the control circuit 26 controls the shutoff device 29 to shut off the water passage from the water tank 4 to the vaporization chamber 3.

As described above, the water is dripped into the vaporization chamber 3 only when the surface of the iron body on which the base 19 is hung is horizontal, that is, only when the ironing is actually performed. Therefore, unnecessary steam is generated. Without base 1
9 will not be cooled needlessly. As a result, the steam duration can be increased.

Further, even when the temperature of the vaporization chamber 3 of the base 19 becomes lower than the appropriate vaporization temperature of water, the control circuit 26 controls the shutoff device 29 by the signal of the thermistor 14 to vaporize from the water tank 4. Needless to say, it has a function of blocking the water channel to the chamber 3.

Next, a second embodiment of the present invention will be described with reference to FIG. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted. As shown in the figure, the control circuit 31 controls energization to the heater 1 included in the base 19 in a state where the iron body is placed on a stand (not shown). The thermistor 32 transmits temperature information of the base 19 to the control circuit 31. Contact detection means 33
Detects that the bottom surface of the base 19 of the iron body has come into contact with a solid material such as cloth. The shutoff device 34 controls the flow of water from the water tank 4 to the vaporization chamber 3 in conjunction with the contact detection means 33.

When the bottom surface of the base 19 is not in contact with the cloth or the like, the shut-off device 3
4, the supply of water to the vaporization chamber 3 is stopped. The power supply circuit 35 supplies power for operation to the control circuit 31, the contact detection means 33, the cutoff device 34, and the like even when the iron main body is detached from the stand.

The operation of the above construction will be described. The iron body is placed on a stand, and after the base 19 has reached a predetermined temperature, the iron body is detached from the stand to iron an object such as cloth. If so,
The contact detection means 33 is in a state of not outputting a signal,
During this time, the control circuit 31 continues to output a signal to the shutoff device 34 to open the water channel.

When the operation of returning the iron body to the stand is performed, or the iron body is floated from a solid material such as cloth to change the ironing position,
The contact detecting means 33 sends a signal to the control circuit 31, and the control circuit 31 controls the shutoff device 34 to shut off the water path from the water tank 4 to the vaporization chamber 3.

As described above, according to the present embodiment, water drops into the vaporizing chamber 3 only when the bottom surface of the base 19 of the iron body comes into contact with a solid material such as cloth. No generation occurs, and the base 19 is not cooled unnecessarily. As a result, the steam duration can be increased.

Similarly to the first embodiment, even when the temperature of the vaporization chamber 3 of the base 19 becomes equal to or lower than the appropriate vaporization temperature of water, the control circuit 31 sends a signal from the thermistor 32 to the shut-off device 34. , The function of shutting off the water path from the water tank 4 to the vaporization chamber 3 is needless to say.

Needless to say, there is no problem even if a function of temporarily generating increased steam is provided by forming a water channel to another vaporization chamber 3 without passing through the shut-off device 34.
