The opening/closing shaft 44 is configured by a spring 843 that urges the opening/closing shaft 44 to be closed, and a shaft guide 45 that movably holds the opening/closing shaft 44. The opening/closing shaft 44 has an outer diameter smaller than an inner diameter of the mouth 40 of the water channel B41, and is configured to be able to freely move within the mouth 40. In this configuration, when the iron main body 10 is removed from the stand 24, the opening 35 of the water channel A36 is closed by the ball A37, as described above.

Similarly, the mouth 40 of the water channel B41 is also blocked by the ball B42. Here, when the iron main body 10 is placed on the mounting part 34 of the stand 24, the opening/closing shaft 44 overcomes the resistance of the spring A38 and spring B43, opening the ball A37 and the hole B42 to the opening 35 and the edge 40, respectively.
further apart, so that water passages are formed.

Next, the operation of the configuration of this embodiment will be explained. First, in order to iron, the iron body 10 is placed on the placing part 34 of the stand 24, the power is turned on, and the temperature setting means 30 of the stand 24 is operated to set the base 13 to a desired temperature. Then, the signal processing means 22 outputs a signal to the control means 29 via the signal terminal 21 in accordance with the output of the temperature detection means 15. Heater 1 responds to this signal.
4 is energized via the power supply pin 23 and the power supply terminal 25, and the base 13 rises to the set temperature. moreover,
When the power is turned on, the control means 29 starts operating, and at the same time, the signal processing means 22 outputs a signal to the control means 29 via the signal terminal 21 in accordance with the output of the water amount detection means 18. That is, if the water in the tank 17 of the iron body 10 is not full, the water supply device 28 is driven in response to this signal until a full water signal is obtained from the signal terminal 21. As mentioned above, the iron body 10 is placed on the stand 24.
When the water supply port 26 of the valve device 20° is placed in the open state due to the operation of the opening/closing shaft 44, ball A37, ball B42, etc., the water in the water storage tank 27 is transferred to the water supply device 28, The water is sent to the tank 17 through the water supply port 26, the valve device 20, and the inlet 19. Here, iron body 1
When the iron is removed from the mounting part 34 and ironed, the water in the tank 17 flows through the water conduit 16 to the vaporization chamber 12.
The steam is vaporized in the vaporization chamber 12 and ejected from the bottom surface of the base 13 as steam.

Next, when the iron main body 10 is placed on the inclined placing part 34, the signal terminal 21 and the power supply pin 23 are connected to the power supply terminal 25, and the valve device 20 and the water supply port 26 are also connected in the same way. The heater 14 is energized and the tank 17 is supplied with water as shown in FIG.

If ironing is continued with steam emitted in this way, the amount of water in the water storage tank 27 will decrease, and eventually there will be no water left, resulting in an "empty" state. At this time, when the iron body 10 is placed on the stand 24, the water supply device 2 waits until the full water signal is obtained from the signal terminal 21 as described above.
8 continues driving. When this state continues for a preset predetermined time (T1), the water supply display means 32 turns from off to on, and furthermore, the water supply notification means 33 starts reporting. Therefore, the operator can know the "empty" state of the water storage tank 27 through this display and notification, and can immediately fill the water storage tank 27 with water.

The above-mentioned predetermined time (T1) can be set using the iron main body 10.
If the setting is set to be slightly longer than the time required for the water supply device 28 to operate until the tank 17 changes from the "empty" state to the "full" state, during normal ironing when water remains in the water storage tank 27, The water supply display means 32 and the water supply notification means 33 do not display or notify. Specifically, if it takes about 5 seconds for the water supply device 28 to drive the tank 17 of the iron body 10 from an empty state to a full state, the predetermined time should be set to be longer than that, for example. It may be about 7 to 8 seconds.

In the above embodiment, when a water supply device such as a pump is driven for a predetermined time (T1) or more, both the water supply display means and the water supply notification means display and notify, but either one may be used, and the point is Any device may be used as long as the operator can visually, audibly, or the like detect this when the water supply device is driven for a predetermined time (T1) or longer.

In FIG. 4, when the water supply device 28 such as a pump has been driven for a predetermined time (T1) or more, the drive of the water supply device 28 is stopped, and as explained in the above embodiment, the stand 2
If the water supply device 28 continues to operate until water is supplied to the water storage tank 27 when the water storage tank 27 of No. 4 becomes "empty", the "empty" state of the water storage tank 27 will be repeated frequently. If this occurs, the durability of the water supply device 28 may be impaired. In order to prevent this, when the water supply device 28 has been driven for a predetermined time (T1) or more, the drive of the water supply device 28 is stopped to improve reliability.

The predetermined time (T1) in this embodiment is also set to be slightly longer than the time required for the water supply device 28 to operate until the tank 17 of the iron body 10 changes from the "empty" state to the "full J" state, as in the previous embodiments. Then, during normal ironing when water remains in the water storage tank 17, the water supply device 28 will not stop when necessary, and a stable jet of steam can be obtained during the ironing work.
This can improve the durability of the water supply device.

Effects of the Invention As described above, in the present invention, when the water supply device is continuously operated for a predetermined period of time or more, it is possible to detect by display or notification that the water in the water storage tank of the stand has run out. The water tank can be replenished with water, allowing for efficient steam ironing work.

Also, if the water in the stand's water tank runs out,
Since the driving of the water supply device is immediately stopped, the water supply device is not driven continuously for a long period of time, and the durability of the water supply device is improved and a highly reliable ironing device can be realized.
