Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ironing device for removing wrinkles from clothing.

0002

[Prior Art] Conventionally, this type of ironing device has adopted a structure as shown in, for example, Japanese Unexamined Patent Publication No. 58-29498, and more specifically, it has a structure as shown in FIG. . That is, the stand 1 has a water storage tank 2 and a mounting part 3.
By placing the iron main body 4 on the above-mentioned placing section 3, water is supplied to a tank 5 within the iron main body 4.

0003

[Problems to be Solved by the Invention] However, with such a structure, water is supplied to the iron body 4 by using the water head pressure of the water storage tank 2 by communicating the iron body 4 with the water storage tank 2. However, there was a problem in that the time required to supply a predetermined amount of water to the iron body 4 was not constant. That is, as the water level in the water storage tank 2 changes, the water head pressure also changes, and as a result, the water supply rate also changes.

[0004] One possible solution to this problem is to supply water using a water supply device such as a pump, but in order to drive this water supply device, an electronic circuit must be installed in the iron body or stand. The iron body requires a water amount detection means for the tank 2 and a water amount signal generation circuit for transmitting the water condition detected by the water amount detection means to the stand side as a signal.

[0005] The conventional iron body side equipped with an electronic circuit has a temperature detection means for detecting the temperature of the heater, and a circuit that drives a circuit to display or notify by the output of this temperature detection means when the iron body is detached from the stand. However, in addition to these electronic circuits, a new water flow signal generation circuit is required.

[0006] In other words, if such a water amount signal generating circuit is further installed and operated, the capacity of the power supply installed in the conventional iron body will be exhausted quickly, and in order to maintain the same power life as the conventional iron, it is necessary to However, the problem is that the capacitance increases and the mounting area of the electronic circuit also increases, making it difficult to mount it in the narrow space of a small device such as an iron.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an ironing device that can reliably supply water to the iron body and has a smaller mounting area for electronic circuits.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the ironing device of the present invention includes a water amount detection means for detecting the water amount in a tank in the iron body, and an output signal of this water amount detection means. A water amount signal generation circuit that generates a signal, a water supply device that is driven by the output from the water amount signal generation circuit, and a placement detection means that detects that the iron main body is placed on the stand. When the placement detection means does not detect placement of the iron body, the operation of the water amount signal generation circuit is stopped.

[0009]

[Operation] Due to the above configuration, the ironing device of the present invention, when the iron body is placed on the stand during use,
Since the power supply installed in the iron body is charged, the water quantity detection means and the water quantity signal generation circuit are driven without depleting the power supply capacity, and the water supply device can be operated to supply water to the iron body.

Furthermore, when the iron body is removed from the stand, the placement detection means stops driving the water amount detection means and the water amount signal generation circuit, thereby reducing power consumption. Therefore, water can be reliably supplied to the iron body using a small, low-capacity power source.

Next, the operation of this embodiment will be explained. First, to iron the iron body 10
Place it on the mounting part 34 of the stand 24, turn on the power,
When the temperature setting means 32 of the stand 24 is operated to set the base 13 to a desired temperature, the temperature detecting means 15
The signal processing circuit 35 outputs a signal to the control means 37 via the signal terminal 21 in response to the output.

In response to this output signal, the heater 14 is energized via the power supply pin 22 and the power supply terminal 25, and the base 13 rises to the set temperature. When the base 13 reaches the appropriate temperature, the iron body 10 is heated. The LED of the attached appropriate temperature display circuit 16 lights up.

Furthermore, when the power is turned on, the control means 3
