Abstract

PURPOSE:To increase durability of a water feeder supplying water to an electric iron body and realize a reliable iron device by feeding water to the iron body smoothing creases of clothes when it is placed on a stand. CONSTITUTION:An electric iron device is provided with a water feeder 28 supplying water in a water storage tank 27 equipped in a stand 24 to the tank 17 of the iron body 10 and a water level detector 18 checking the water level within the water tank 17 of iron body 10. When the tank 17 of iron body 10 is detected by the level indicator 18 to be in full water, the drive of water feeder 28 is stopped for a certain interval. In this way, intermittent actuation of the water feeder 28 due to intermittent full water signals of the water level detector 18 resulting from water splashing or fluctuation of water level at the time when water is fed into the tank 17 of iron body 10 can be prevented.

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, the water supply device of this type of ironing device was generally driven according to a time chart as shown in FIG.

That is, when the iron is placed on the stand, water is supplied when the output signal from the water level detection means is in the "empty" state, and when the iron is in the "full" state, the water supply and drainage device is stopped. The operation was synchronized with the output signal from the water level detection means.

0004

However, in such a method, as shown in FIG. 4, when the output signal from the water level detection means is unstable, the water supply device also operates unstablely. In other words, when water is supplied to the tank of the iron body, the output signal from the water level detection means intermittently outputs a "full" state signal due to splashing of the water in the tank or fluctuations in the water level, so the water supply device is not driven. There was a problem in that this was done intermittently, which significantly shortened the life of the water supply device.

[0005] Accordingly, an object of the present invention is to improve the durability of a water supply device and realize a highly reliable ironing device.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides water level detection means to
When "full water" is detected, the water supply system is stopped for a certain period of time.

[0007]

[Function] With the above configuration, the ironing device of the present invention has the above structure, so even if the water level detection means intermittently outputs a "full water" signal during water supply, the water supply device is stopped, so the intermittent operation of the water supply device is prevented. This can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 to 4, reference numeral 10 denotes an iron body, and a base 1 has a vaporizing chamber 12 covered with a lid 1.
3. A heater 14 that heats the base 13; a temperature detection means 15 such as a thermistor that detects the temperature of the base 13;
, a tank 17 connected to the vaporization chamber 12 via a water conduit 16, a water level detection means 18 comprising an electrode or the like for detecting the amount of water in the tank 17, and a water inlet 19 for supplying water to the tank 17. , a valve device 20 for opening and closing this water inlet 19, the temperature detection means 15, and the water level detection means 1.
a signal processing means 22 composed of a plurality of electronic components that processes and superimposes the output signals of 8 and outputs them to the signal terminal 21;
It has a power supply pin connected to the heater 14.

Reference numeral 24 denotes a stand, and a water supply port 2 is connected to the signal terminal 21 and the power supply pin 23 of the iron body 10, respectively.
6. A water storage tank 27 for storing water, a water supply device 28 comprising a pump, etc. for supplying the water stored in the water storage tank 27 to the tank 17 via the water supply port 26 and the valve device 20, and the signal A control means 2 comprising a plurality of electronic components that receives an output signal from the processing means 22 and controls energization of the heater 14 and driving of the water supply device 28.
9. Temperature setting means 30 for setting the base 13 to a desired temperature, set temperature display means 31 for displaying the set temperature state with an LED or the like, and tilting the iron main body 10 with the base facing downward. It has a mounting section 34 for holding.

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 30 of the stand 24 is operated to set the base 13 to a desired temperature, the temperature detection means 15
The signal processing means 22 outputs a signal to the control means 29 via the signal terminal 21 in response to the output.

In response to this signal, the heater 14 is energized via the power supply pin 23 and the power supply terminal 25, and the base 13
will rise to the set temperature. Further, when the power is turned on, the control means 29 starts operating, and at the same time, the signal processing means 22 outputs a signal to the control means 29 via the signal terminal 21 in accordance with the output of the water level detection means 18. That is, if the water in the tank 17 of the iron body 10 is not full, the water supply device 28 is driven in response to this signal until a full water signal is obtained from the signal terminal 21, and the water in the water storage tank 27 is supplied to the water supply device. 28, water supply port 26, valve device 2
0, is sent to the tank 17 through the inlet 19.

[0012] Here, the water level detection means 18 once detects "full water".
If detected, the drive of the water supply device is stopped for a certain period of time (T1) regardless of the content of the signal. In addition, the iron body 1
When the 0 is removed from the mounting part 34 and ironed, the water in the tank 17 is sent to the vaporization chamber 12 through the water conduit 16, vaporized in the vaporization chamber 12, and ejected as steam from the bottom surface of the base 13. The amount of water in the tank of the iron itself decreases.

Next, when the iron main body 10 is placed on the inclined placing portion 34, the signal terminal 21 and the power supply pin 23 are connected to the power supply terminal 25, and the valve device 20 and the water supply port 26 are also connected in the same manner. Therefore, as mentioned above, the heater 14 is energized and the tank 17 is supplied with water at the same time, and once the water level detection means 18 detects "full water", the water level is energized for a certain period of time (T1) regardless of the content of the signal. Driving of the water supply device 28 is stopped.

Here, the above-mentioned fixed time (T1) is set according to the water level signal output due to water splashing in the tank 17 of the iron main body 10 or shaking of the water surface when water is supplied, as shown in FIG. If the setting is set slightly longer than the time (Ta) for which the intermittent "full water" state signal is output, the water supply device 28
is not driven intermittently.

Specifically, if the unstable time of the water level signal output that occurs near the water crossing the water level detection means 18 during water supply is 0.5 seconds, the setting of the constant time (T1) is It may be longer, for example, about 1 to 2 seconds.

[0016] In the above embodiment, a certain period of time (T1)
The setting was set to be slightly longer than the time (Ta) during which the intermittent "full water" state signal of the water level signal output due to water splashing in the tank 17 or shaking of the water surface is output. As shown in the figure, the water supply device is stopped for a certain period of time (
The setting of T1) may be set to be the same as the time (Tb) from when the iron is removed from the stand after "full water" is detected until the iron is returned to the stand again.

Specifically, the water supply device 28 is driven only once at most during one cycle in which the iron is placed on the stand and the iron main body 10 is removed from the stand 24 again. Therefore, the water supply device 28
Since the water supply device 28 is not driven intermittently, the durability and reliability of the water supply device 28 can be improved. The point is that the water supply device does not need to be driven intermittently.

[0018]

Effects of the Invention As described above, the present invention stops the driving of the water supply device for a certain period of time when the water level detection means detects that the tank is "full of water," so that the water level detection means generates a "full water" signal at the time of water supply. Even in the case of intermittent output, the water supply device is stopped, which prevents intermittent operation of the water supply device, improving the durability and reliability of the water supply device, and also preventing intermittent operation of the water supply device. Sound can also be reduced.
