Abstract

PURPOSE:To prevent water leakage at the time of removing an iron body from a stand to enhance safety and improve reliability by driving a water feeding device in the opposite direction to water feeding time for a determined time, in case of separating the inlet port of the iron body from the water feed port of the stand. CONSTITUTION:When an iron body 10 is removed from a placing part 31 for ironing, a control means 21 detects the removal of the iron body 10 due to no temperature signal inputted thereto, and starts to drive a water feeding device 27 with reverse rotation to water feeding time. This reverse rotating drive is stopped within a determined time. When the iron body 10 is removed from the placing part 31 during this drive, the water stored in the internal space of the packing 36 of a feed valve device 25 is returned to a storage tank 26 through a water passage in the feed valve device 25, without leaking out of a stand 23. As no water is leaked from the outlet of the feed valve device 25, the possibility of electric shock by leaked water and the failure of a control circuit are eliminated, and safety and reliability are improved.

It has a set temperature display means 30 for displaying on an ED or the like, and a mounting section 31 for mounting the iron main body 10 on the front side with one step downward.

Here, the above-mentioned valve device 19 and water supply valve device 25 will be explained in detail. As shown in FIG.
2, a ball A34 that is freely movable in the water channel A33, and a ball A34 that allows the opening 32 to move freely within the water channel A33.
4 and a spring A35 that urges it to close. On the other hand, the water supply valve device 25 includes a waterway B38 having a notch 36 and an opening 37 for sealing connection when connected to the waterway A33;
8, the ball B39 is freely movable, and the small opening 37
It is composed of a spring B40 that urges the opening and closing shaft 41 to be closed by the hole B38, an opening and closing shaft 41, and a shaft guide 42 that movably holds this opening and 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 water channel A33
The opening 32 is closed by a ball A34. Similarly, the mouth 37 of the water channel B38 is also blocked by the hole B39. Here, place the iron body 10 on the stand 2.
3, the opening/closing shaft 41 overcomes the resistance of the spring A35 and the spring B40 to separate the balls A34 and B39 from the opening 32 and the edge 37, respectively, and as a result, a water passage is formed. It becomes like this.

Next, the operation of the configuration of this embodiment will be explained.

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 at the same time, the water supply device 27 is driven to rotate in the forward direction. 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 open to the operation of the opening/closing shaft 41, ball A34, ball B39, etc. Water in the water storage tank 26 is sent to the tank 17 through a water supply device 27, a water supply valve device 25, a valve device 19, and an inlet 18.

Here, when the iron main body 10 is removed from the mounting portion 31 and ironing is performed, the signal terminal 20 and the power supply pin 22 are separated from the power supply terminal 24, so that no temperature signal is input to the control means 21. The control means 2] detects that the iron body 10 has been removed from the stand 23, and starts driving the water supply device 27 in the opposite direction to the rotation when water is supplied. This reverse rotation drive stops after a predetermined time, but when the iron main body 10 is removed from the placement part during this drive, the water that has accumulated in the internal space of the backing 36 of the water supply valve device 25 is released to the outside of the stand 23. It does not leak and is returned to the water storage tank 26 through the water channel in the water supply valve device 25.

As mentioned above, even if the iron main body 10 is removed from the stand 23 and ironing is performed while the water supply device 27 is operating to supply water, water will not leak from the connection part of the water channel, that is, the outlet of the water supply valve device 25. Since there is no risk of electric shock due to leaking water or failure of control circuits, etc., safety and reliability are improved.

In the above embodiment, an example of a cordless iron is shown in which the iron body does not have a power cord, but a corded ironing device having a power cord in the iron body may also be used. The point is that when the iron body is removed from the stand, the water supply device may start rotating in the opposite direction from when water is being supplied.

Effects of the Invention As described above, in the present invention, when the inlet of the iron main body and the water supply port of the stand are separated, the water supply device is driven to rotate in the opposite direction to that when water is supplied for a predetermined period of time, and water accumulates near the outlet of the water channel. In order to send the water that was being stored to the water storage tank inside the stand,
It is possible to prevent leakage of water, prevent failure of circuits, etc., and improve reliability and safety by preventing electric shock due to electric leakage.
