A control means 28 composed of a plurality of electronic components for controlling the drive of the base 13, a temperature setting means 29 for setting the base 13 to an arbitrary temperature, and a set temperature display means for displaying the set temperature state with an LED or the like. 30, the iron main body 1
It has a mounting part 31 on which the 0 is mounted at an angle with the base facing downward.

Here, the above-mentioned valve device 19 and water supply valve device 25 will be explained in detail. As shown in FIG.
A water channel A33 having
It is composed of a spring A35 that urges the valve to close. The water supply valve device 25 includes a backing 36 for sealing connection when connected to the water channel A33, a water channel 838 having a small opening 37, a ball B39 disposed freely in the water channel 838, and a ball B39 that closes the small opening 37 with the ball B38. Spring B40 that urges
．． It is composed of an opening/closing pongee 41 and a shaft guide 42 that movably holds this opening/closing shaft 41. The opening/closing shaft 41 has an outer diameter smaller than an inner diameter of the mouth 37 of the water channel B38, and is configured to be able to freely move within the mouth 37. In this configuration, when the iron main body 10 is removed from the stand 23, the opening 32 of the water channel A33
is blocked by ball A34. Similarly, the mouth 37 of the water channel B38 is also blocked by the ball B39. Here, when the iron main body 10 is placed on the mounting portion 31 of the stand 23, the opening/closing shaft 41 is moved to the spring A35.
, each ball A3 overcomes the drag force of spring B40.
4. Move the ball B39 away from the opening 32 and the edge 37, so that a water passage is formed.

The operation of the above configuration will now be described.

First, to iron, place the iron main body 10 on the placing part 31 of the stand 23, turn on the power, and operate the temperature setting means 29 of the stand 23 to set the base 13 to a desired temperature. In response to the output of the temperature detection means 15, the temperature signal processing means 21 outputs a signal to the control means 28 via the signal terminal 20. In response to this signal, the heater 2 is energized via the power supply pin 22 and the power supply terminal 24, and the base 13 rises to the set temperature.

Further, when the power is turned on, the control means 28 starts operating and the water supply device 27 is driven at the same time. When the iron main body 10 is placed on the stand 23 as described above, the water channels of the valve device 19 and the water supply valve device 25 are connected to the opening/closing shaft 4.
1. Since the ball A34, ball B39, etc. are in an open state, the water in the water storage tank 26 is drained to the water supply device 27,
The water is sent to the tank 17 through the water supply valve device 25, the valve device 19, and the inlet 18.

Here, when the iron main body 10 is removed from the mounting part 31 and ironing is performed, water in the tank 17 is sent to the vaporizing chamber 12 through the water conduit 16, vaporizes in this vaporizing chamber 12, and returns to the base 13 as steam. It gushes out from the bottom. At this time, the water supply device 27 is in the driving state, but since the water channel is blocked by the ball B39 as described above,
Water does not flow out from the water supply valve device 25.

Next, when the iron main body 10 is placed on the inclined placing part 31, the signal terminal 20 and the power supply pin 22 are connected to the power supply terminal 24, and the valve device 19 and the water supply device 25 are also connected in the same way, so the above-mentioned The heater 2 is energized and the tank 17 is supplied with water as shown in FIG.

Therefore, simply by placing the iron main body 10 on the above-mentioned inclined mounting portion 31, the connection of the water channels is reliably performed, so there is no need to pay attention to the connection state of the water channels, and the iron main body 10 can be placed in an independent state. Since there is no need to set the device down, the usability is greatly improved.

Furthermore, since it is a cordless iron that energizes the heater 14 while it is placed on the stand 23, there is no tangle of cord during ironing, and there is no need to worry about the cord getting tangled during ironing.
3 can be easily placed, and the usability is further improved.

In the above embodiment, an example was shown in which the water in the water storage tank is supplied to the tank in the iron body using a water supply device such as a pump, but a supply method that utilizes the water head difference between the water storage tank and the tank in the iron body may also be used. The point is that when the iron body is placed on the stand, a waterway is formed and water can be supplied.

Next, other embodiments of the present invention will be described.

FIG. 4 shows another embodiment in which the water supply device 27 is driven in response to the placement of the iron body 10 on the stand 23. First, place the iron body 10 on the stand 23
When the base 13 is set to a desired temperature by the temperature setting means 29, the temperature signal processing means 21 controls the control means 2 via the signal terminal 20 according to the output of the temperature detection means 15.
Outputs a signal to 8. In response to this signal, the heater 2 is energized via the power supply pin 22 and the power supply terminal 24. Further, the temperature signal is transmitted from the temperature signal terminal 2 to the control means 28.
The control means 28 recognizes that the iron body 10 is placed on the stand 23 and drives the water supply device 27 to supply the water in the water storage tank 26 to the iron body 1.
Supply to tank 17 in 0.

Next, when the iron main body 10 is removed from the mounting part 31 of the stand 23 and ironing is performed, the signal terminal 20 and the power supply pin 22 are not in contact with the power supply terminal 24, respectively.
No temperature signal is input to the control means 28. Since there is no input signal, the control means 28 detects that the iron body 10 is not on the stand 23 and stops driving the water supply device 27. Again, the iron main body 10 is tilted on the mounting section 3.
1, the signal terminal 20 and the power supply pin 22 are connected to the power supply terminal 24, and the valve device 19 and the water supply valve device 25 are connected to the power supply terminal 24.
are connected in the same way, so that the heater 2 is energized and the tank 17 is supplied with water as described above.

Therefore, simply by placing the iron main body 10 on the above-mentioned inclined mounting portion 31, the waterway can be reliably connected, and water is supplied to the tank after the waterway is securely connected. Since there is no need to pay attention to the connection state of the iron body 10, and there is no need to place the iron body 10 in a free-standing state, the usability is greatly improved.

Furthermore, since it is a cordless iron that energizes the heater 14 while it is placed on the stand 23, there is no tangle of cord during ironing, and there is no need to worry about the cord getting tangled during ironing.
3 can be easily placed, and the usability is further improved.

In the above embodiment, an example was shown in which the detection of the placement of the iron body on the stand is determined based on the presence or absence of a temperature signal from the signal terminal, but for example, a limit switch or the like is activated by the placement of the iron body on the stand. The water supply device may be detected in a non-contact manner by an object or reed switch, etc., and the point is that the water supply device is activated after detecting that the iron body is placed on the stand, and when the iron body is removed, the water supply device is activated. It is fine as long as it stops.

FIG. 5 shows still another embodiment, in which the water capacity of the tank 17 in the iron main body 10 is smaller than the water capacity of the water storage tank 26 of the stand. In this case, since the tank 17 of the iron body 10 can be configured to be small, the iron body 10 itself can also be configured to be small.

Furthermore, since the amount of water stored in the iron body 10 is small, the total weight of the iron body 10 when ironing is also reduced, resulting in a small, light and easy-to-use ironing device.

Effects of the Invention As described above, the present invention controls the energization of the heater circuit and the water supply to the tank in response to the placement of the iron body on the stand, thereby eliminating the need to pay attention to the connection state of the water channel. Both irons are easier to use by simply placing the iron on the stand, allowing electricity to be applied to the heater and water to be supplied to the tank.

Further, by operating the water supply device in response to the placement of the iron body on the stand, water can be reliably supplied to the tank of the iron body.

Furthermore, since the capacity of the tank of the iron body is set to be smaller than the capacity of the water storage tank of the stand, the size and weight of the iron body can be reduced, making it possible to realize an ironing device that is easier to use.
