Description

[Detailed description of the invention]

[00011

[Field of Industrial Application] The present invention relates to an ironing device in which water is supplied to an iron for removing wrinkles from clothing by placing the iron on a stand. [0002] Conventionally, this type of ironing device has been disclosed in Japanese Patent Laid-Open No. 58-29498, for example.
The water supply stand has a place for placing the iron and a water tank.
By placing the iron on the above-mentioned placement section, the difference in water head between the water tank of the water supply table and the iron tank is utilized.
Water was supplied to the tank inside the iron. [0003]

[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 iron tank, even if the water inlet and the water supply inlet are not fully fitted, water will be supplied if the water channel is opened. As a result, not only is it not possible to reliably supply water to the iron, but there is also a risk that water may leak from the fitting portion. [0004f Therefore, if the iron is placed tilted or placed slowly during a short break during ironing work, the risk of water leakage will increase, so the operator should always be careful about how the iron is placed. It was extremely difficult to work. Also, if water leaks,
There were also problems with safety, such as stains on clothing and the risk of electric shock. [0005] Therefore, the present invention solves the above conventional problems, and aims to provide an ironing device that prevents water leakage, improves ironing workability, and enhances safety. . [0006]

[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, a control means for controlling the drive of this water supply device, Further, a placement detection means for detecting that the iron body is placed on the placement portion is provided, and water supply is started after a predetermined period of time has elapsed since the iron body was placed on the stand. [0007]

[Operation] The operation of this technical means is as follows. That is, when the iron body is placed on the stand, the placement detection means detects that the iron body is placed on the stand. At this time, the water inlet of the iron body and the water inlet of the stand are connected, but the timing of this placement detection and the connection of the water inlet of the iron body and the water inlet of the stand may vary depending on how the iron is placed. be done. Therefore, after the placement detection means detects that the iron body is placed at a predetermined position on the stand, the water supply device is activated after a predetermined period of time has elapsed. Therefore, water is supplied only after the water inlet of the iron body and the water inlet of the stand are reliably connected, and water leakage can be prevented. [00081

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 and 2, reference numeral 10 denotes an iron body, a base 12 having a vaporization chamber 11 for generating steam, and a heater 13 for heating this base 12.
, a temperature detection means 14 such as a thermistor for detecting the temperature of the base 12, a tank 15 connected to the vaporization chamber 11,
A water inlet 16 for supplying water to the tank 15, a temperature signal processing means 18 comprised of a plurality of electronic components that processes the output signal of the temperature detection means 14 and outputs it to the signal terminal 17, connected to the heater 13. It has a power supply pin 19. [0009] Reference numeral 20 denotes a stand on which the iron body 10 is placed, and is connected to a plurality of power supply terminals 21 each connected to the signal terminal 17 and the power supply pin 19 of the iron body 10, and 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 including a pump 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 temperature signal processing. A control means 25 constituted by a plurality of electronic components that receives an output signal from the means 18 and controls energization of the heater 13 and driving of the water supply device 24, and a temperature for setting the base 12 to an arbitrary temperature. The mounting includes a setting means 26, a temperature display means 27 for displaying the set temperature state using an LED or the like, and a limit switch for detecting that the iron main body 10 is placed at a predetermined position on the mounting section. It has position detection means 28. [00101 Next, the operation of the configuration of this embodiment will be explained. First, to perform ironing, place the iron body 10 on the placement part of the stand 20, turn on the power, and operate the temperature setting means 26 of the stand 20 to set the base 12 to a desired temperature. , the temperature signal processing means 14 outputs a signal to the control means 25 via the signal terminal 17 in response to the output of the temperature detection means 14. In response to this signal, the heater 13 is energized via the power supply bottle 19 and the power supply terminal 21, and the base 12 rises to the set temperature. [00111 Furthermore, when the power is turned on, the control means 2
5 starts operating, the placement detection means 28 detects that the iron body 10 is placed, and a predetermined time (T) has elapsed since the placement of the iron body 10 was detected. Thereafter, the water supply device 27 is driven by the control means 28, and the water in the water storage tank 26 is supplied to the tank 15 of the iron body 10. [0012] Here, when the iron main body 10 is removed from the mounting part and ironing is performed, the water in the tank 15 is sent to the vaporization chamber 11, vaporizes in this vaporization chamber 11, and is ejected from the bottom surface of the base 12 as steam. do. [0013] Next, when the iron main body 10 is placed on the placing section, the iron main body 10 is
is detected, and the signal terminal 17 and power supply bottle 19 are connected to the power supply terminal 21. Further, as described above, after a predetermined time (T) has elapsed since the placement of the iron main body 10 is detected by the placement detection device 28, the water supply device 27 is driven by the control device 28, and water is supplied to the tank 15. [0014] The predetermined time (T) is set by assuming that the time required for the water inlet 16 and the water inlet 22 to be reliably connected after the placement of the iron main body 10 is detected by the normal placement detection means 28 is set to 0. If it is about 5 seconds, for example 1
If you set it to about seconds or more, water inlet 16, water inlet 22
Water is supplied after the iron body 10 is securely connected, and no matter how the iron body 10 is placed on the stand 20, water leakage from the connection between the iron body 10 and the stand 20 can be prevented. , water can be reliably supplied to the iron body. [0015] Therefore, when the iron body 10 is placed on the stand 20, which is frequently repeated during work, even if the iron body 10 is placed tilted or placed slowly, the connection of the water channel is ensured. Since water is supplied after the ironing process has been completed, water leakage is reliably prevented, which not only improves ironing efficiency but also eliminates the risk of getting clothes wet and staining, further improving safety. It is something that can be done. [0016] In the above embodiment, an example was shown in which a limit switch that opens and closes depending on the weight of the iron body is used as a placement detection means for detecting placement of the iron body on the stand. The stand may be a reed switch that is provided with a magnetic material and that opens and closes using the magnetic material, or a Hall element that changes the output.
In short, any device that can detect that the iron body is placed on the stand is sufficient. [0017] [Effects of the Invention] As described above, the present invention reliably prevents water from leaking from the connection between the iron body and the stand by supplying water after a predetermined time has elapsed after the iron body is placed on the stand. It can be prevented. Therefore, the frequent operation of placing the iron on the stand during short breaks during ironing work is facilitated, improving usability and increasing safety by preventing dangers such as electric shock due to water leakage.
