However, in such a structure, since the iron body 4 and the water tank 2 are communicated with each other, the water head pressure of the water tank 2 is used to supply water to the iron body 4. However, there is a problem that the time for supplying a predetermined amount of water to the iron body 4 is not constant. That is, the water head pressure changes as the water level in the water tank 2 changes, and as a result, the water supply speed also changes.

Further, in such a structure that uses the water head pressure of the water tank 2, the water tank 2 must be installed above the iron body 4, so that when the iron body 4 is placed on the stand 1 or removed. In order to improve the operability and reduce the size of the device, even if the height of the iron body 4 is lowered and the height of the iron body 4 is set so as to be tilted forward and upward, as described above, The water tank 2 still had to be provided above the iron body 4, and it was not possible to promote miniaturization of the entire apparatus.

As a means for solving such a problem, a method of forcibly supplying or draining water by using a water supply / drainage device such as a pump device can be considered, but the drainage operation is performed without the water tank being securely mounted. When it is done, water in the iron body leaks out, and there is a problem that stains or stains are attached to clothes or the like being ironed. Further, if the leaked water adheres around the electric control parts in the stand, there is a risk of malfunction or electric shock.

Therefore, an object of the present invention is to provide a safe ironing device which is free from the risk of stains or stains on clothes or malfunctions or electric shock due to careless water leakage caused by a user's mishandling.

[0007]

In order to achieve the above-mentioned object, the ironing device of the present invention uses the output signal of the water amount detecting means of the iron body to supply water in the water tank to the iron body tank. And a water supply / drainage device for discharging the water from the tank to the water storage tank, and a water storage tank detection means for detecting whether or not the water storage tank is mounted on the stand, and the water storage tank is not mounted on the stand by the water storage tank detection means. At this time, the driving of the water supply / drainage device is stopped.

[0008]

According to the ironing device of the present invention, even if the user mistakenly performs draining operation while the water tank is removed from the stand, the ironing device of the present invention can stop the driving of the water supply / drainage device by the water tank detecting means. become able to.
Therefore, it becomes possible to reliably prevent water from leaking from the iron body, and such inadvertent water leakage can be used safely without the risk of stains or stains on clothes, malfunctions or electric shock. You can do it.
