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

0002

2. Description of the Related Art Conventionally, this type of ironing device has a structure as shown in FIG. 4, as shown in, for example, Japanese Patent Application Laid-Open No. 58-29498.

That is, the water supply table 1 is provided with a placing part 3 for placing the iron 2 and a water tank 4, and by placing the iron 2 on the above-mentioned placing part 3, the water tank 4 of the water supply table 1 is installed.
By using the water head difference between the iron 2 and the iron 2 tank, water was supplied to the tank inside the iron 2.

0004

[Problem to be Solved by the Invention] However, with such a structure, when the water inlet provided at the rear of the iron is fitted into the water inlet provided on the placement part of the water supply stand, the water supply stand is closed. Since water is supplied by the difference in water head between the water tank and the tank inside the iron, the time for which water is supplied changes depending on the difference in water head and the degree of fitting of the connection part, and the worker may have to wait until sufficient water is supplied. This caused the inconvenience of removing the iron and causing the water inside the iron to run out during the ironing process.

[0005] Therefore, during a short break during ironing work, the worker must always check whether water has been supplied to the tank within the iron body, which poses the problem of extremely poor work efficiency. Ta.

[0006] Also, when storing the ironing device after ironing work, if water remains inside the iron body, water may leak, or when you want to iron the ironing work without producing steam. There was also the problem that steam would come out due to water remaining inside the iron itself.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide an ironing device that is easy to use and has improved ironing workability.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a water supply device that supplies water in a water storage tank to a tank of an iron body, and a drainage system that returns water in the iron body to a water storage tank. The apparatus is provided with a control means for controlling the driving of the water supply device and the drainage device, and a display device for displaying the driving state of the water supply device and the drainage device.

[0009]

[Function] With the above structure, the ironing device of the present invention allows the display device to display that water is being supplied when the control means drives the water supply device by the operator's operation after starting ironing work. This allows the operator to know that the water supply device is in operation.

[0010] Furthermore, when the ironing work is completed and the iron is to be stored, the drainage device is activated to drain the water in the tank within the iron body. During this time, the display device will be able to display that the water is being drained, allowing the operator to confirm that the water is being drained before storing it away.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 3, reference numeral 10 denotes an iron body, which includes a base 12 in which a vaporization chamber 11 for generating steam is formed, a heater 13 that heats the base 12, and a temperature sensor such as a thermistor that detects the temperature of the base 12. A means 14, a tank 15 connected to the vaporization chamber 11, a water inlet 16 for supplying water to the tank 15, and a plurality of electronic components that process the output signal of the temperature detection means 14 and output it to a signal terminal 17. Temperature signal processing means 1
8. It has a power supply pin 19 connected to the heater 13.

Reference numeral 20 denotes a stand on which the iron body 10 is placed, and a plurality of power supply terminals 21 are respectively connected to the signal terminal 17 and the power supply pin 19 of the iron body 10, and are connected to the water inlet 16 of the iron body 10. Water supply port 22,
A water storage tank 23 for storing water, a water supply device 24 consisting of a pump, etc. for supplying the water stored in the water storage tank 23 to the tank 15 via the water supply port 22 and the water inlet 16, and the water in the tank 15. A drainage device 25 that returns water to the water storage tank 23, and a plurality of electronic components that receive the output signal of the temperature signal processing means 18 and control the energization of the heater 13 and the driving of the water supply device 24 and the drainage device 25. Control means 26 are provided.

Further, the stand 20 includes temperature setting means 27 for setting the base 12 to a desired temperature.
A temperature display means 28 that displays the set temperature state using an LED or the like, a display device 29 that displays the driving states of the water supply device 24 and the drainage device 25, and the iron main body 10 are placed at a predetermined position on the placement section. It has a placement detection means 30 that is configured with a limit switch or the like that detects that the device is placed.

Next, the operation of the configuration of this embodiment will be explained. First, to iron, place the iron main body 10 on the placement part of the stand 20, turn on the power, and operate the temperature setting means 27 of the stand 20 to set the base 12 to a desired temperature. , a signal from the temperature signal processing means 18 is transmitted to the control means 26 in the stand 20 via the signal terminal 17 in response to the output of the temperature detection means 14 in the base 12.

The control means 26 learns the temperature of the base 12 from the transmitted signal and compares it with the value set by the temperature setting means 27. As a result of the comparison, if the temperature of the base 12 is higher than the set value, the control means 26 does not energize the heater 13, and if it is lower than the set value, the control means 26 energizes the heater 13 via the power supply pin 19 and the power supply terminal 21. As a result, base 1
The temperature of No. 2 rises to the set temperature.

Furthermore, the control means 26 controls the temperature setting means 2.
When the steam setting is set in step 7, the water supply device 24 is driven to supply water from the water storage tank 23 of the stand 20 to the tank 15 through the water supply port 22 and the water fill port 16.
At the same time, the display device 29 displays that the water supply device 24 is being driven.

[0017] The operator sees this display and knows that the water supply device 24 is in operation, and starts the ironing work after the water supply is finished. This allows ironing to be done after sufficient water has been supplied.

Next, when the ironing work is finished and the ironing device is to be stored, the operator operates the temperature setting means 27. In this case, the control means 26 stops energizing the heater 13, simultaneously drives the drainage device 25, and displays the information on the display device 29.

Furthermore, even when the steam setting is changed to the dry setting, while the drainage device is being driven, the display device can display that it is being driven.

[0020] In the above embodiment, an example was shown in which the operation of the water supply device or the drainage device is displayed using an LED, but in addition to the display on an LCD or the like, a notification means may also be used. It is only necessary to know that someone is supplying water or discharging water.

Further, in the above embodiment, the display device and the temperature display means are each provided independently, but they may be used in common as long as the operating status of the water supply device or the drainage device is displayed so as to be understood.

[0022]

[Effects of the Invention] As described above, the present invention provides a display device that displays that the water supply device or drainage device is operating when the iron body is placed on the stand and water is being supplied or drained. This allows the operator to know that the device is in operation. Therefore, since the ironing work can be started after water is reliably supplied, the work can be done efficiently without the steam jetting stopping during use.

[0023] Also, when the ironing work is finished, the operator can store the iron after confirming that the water has been drained. Therefore, dangers such as electric shock due to water leakage can be prevented and safety can be improved.
