Abstract

PURPOSE: To report the timing to place an iron body on a stand and the start of a power feeding state to a worker by providing an alarm means with which an alarm is issued when the temperature of a base is lowered during ironing and that alarm is stopped when the iron body is placed on a placing part. CONSTITUTION: When ironing is performed while detaching the iron body 12 from a placing part 28, the time of detaching the iron body 12 from the placing part 28 is detected by an output from a placing detecting means 23, the temperature of a base 14 just before that is stored by a temperature control means 25, and the alarm is issued after the lapse of time t2 converted from the temperature decrease speed of the base 14. Therefore, before the temperature of disabling the vaporization of water at the temperature of the base 14, the timing to place the iron body 12 on a stand 20 can exactly be reported to the worker. When the iron body 12 is placed on the stand 20, that alarm is stopped by confirming a placing state from the output from the placing detecting means 23 by the temperature control means 25 and power feeding is started. Thus, the start of the power feeding state can easily be confirmed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cordless iron for general household use.

BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 3, a cordless iron of this type has a base 2 having a heater 1, a vaporizing chamber 3 provided in the base 2, and a tank 4 disposed above the base.
, a thermostat 6 mounted on the base 2, an iron body 7 having a power supply terminal 6 connected to the heater 1, an electrode 8 connected to the power supply terminal 6, a power cord 9 connected to the electrode 8, and the iron. It was composed of a stand 11 provided with a placing portion 1of on which the main body 6 is placed.

Problems to be Solved by the Invention However, with such a structure, if the iron main body 7 is removed from the stand 11 and used while generating steam without power being supplied to the iron main body 6, the temperature of the base 2 gradually decreases. Even if the water in the tank 4 is supplied to the vaporization chamber 3, the temperature drops to a point where the water cannot be vaporized into steam, resulting in the water leaking out and wetting the fabric. Further, even when the iron is used without generating steam, there is a problem in that when the iron is used for a long time, the wrinkles of the clothes are not smoothed out due to the drop in the temperature of the base 2, even though ironing is performed. Furthermore, since the temperature state of the base 2 is not known, frequently placing the iron body 7 on the stand 11 in order to prevent the base temperature from decreasing significantly impairs the efficiency of ironing work.

Therefore, the present invention not only notifies the operator when the temperature of the base drops and informs the operator when it is time to place the iron body on the stand, but also stops the notification when the iron body is placed on the placing part and makes the power supply state. This is to notify the worker that the

Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
A temperature detection means detects the temperature of the base, a horizontal placement means detects whether or not the iron body is placed, and when the base temperature decreases during ironing, it is notified and the iron body is placed on the placement part. It is equipped with a notification means that stops the notification when the device is placed.

action The effect of this technical means is as follows.

In other words, when the iron body is removed from the stand and ironing is performed while steam is being emitted, the temperature of the base gradually decreases, but the temperature is detected by the temperature detection means, so the temperature of the base gradually decreases. The alarm means alerts the operator before the temperature reaches a point where it is no longer possible to generate steam, informing the operator of the need for power supply, which prevents ironing after the base temperature has dropped, and also prevents the iron from being unnecessarily placed on the stand. You can eliminate wasted money. Moreover, since this notification stops when the iron body is placed on the placement section, it is possible to easily confirm that the iron body is in the power supply state.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

1 and 2, reference numeral 12 denotes an iron body, which includes a base 14 having a heater 13, a vaporization chamber 15 provided in the base 14, a tank 16 disposed above the base 14, and the base 14. a temperature detection means 17 for detecting the temperature of the heater 13; a power supply terminal 18 connected to the heater 13;
It has an output terminal 19 connected to the temperature detection means 17. 2o is a stand, which has an electrode 21 connected to the power supply terminal 18 and an input terminal 2 connected to the output terminal 19.
2, a placement detection means 23 for detecting whether or not the iron body 12 is placed on the stand 2o, and a temperature setting button 24 by inputting the outputs of the temperature detection means 17 and the placement detection means 23. a temperature control means 26 that controls the base 14 at a temperature that has been adjusted; a switching means 26 that is driven by the output of the temperature control means 25 to turn on and off the power supply to the heater 13; and a notification means 27 that uses the temperature control means 26 to issue an alarm. , a placing section 28 on which the iron main body 12 is placed, and a power cord 29 that supplies power to the entire device.

To explain the operation of the above configuration, first, when the iron main body 12 is placed on the stand 2o, the built-in electrode 21 is in contact with the power supply terminal 18 and the stand 2o, so that power can be supplied.

When the temperature of the base 14 is set in the temperature control means 26 by the temperature setting button 24, the temperature control means 26 inputs the base temperature information from the temperature detection means 17 through the output terminal 19 and the input terminal 22, and the temperature is the same as the set temperature. Turn on the switching means 26 to supply power to the heater 13 until the base 1
Heats 4ft.

Next, a case will be described in which the temperature of the base 14 rises and becomes ready for use, the iron main body 12 is removed from the stand 2o, and the iron is applied using steam. When the base 14 reaches a temperature that can vaporize water, remove the iron body 12 from the stand 20. If the iron body 12 is set to use steam, water will pass from the tank 16 to the vaporization chamber 16 and the base 14 will be removed. The heat vaporizes the water and generates steam. This steam is used to perform ironing.

However, when this steam is generated, the heat of vaporization is taken away and the temperature of the pace 14 gradually decreases.

The temperature control means 26 holds the iron body 12 on a stand 20.
The time t from when the base 14 is removed until the temperature of the base 14 drops to a temperature at which steam cannot be generated.

When a shorter time t2 has elapsed, the temperature control means 25 drives the notification means 27 to issue a notification. In the above configuration, when the iron main body 12 is removed from the placement part 28, the base temperature information cannot be obtained from the temperature detection means 17, so the notification start timing of the notification means 27 is determined from the placement detection means 23 The iron main body 12 is moved from the placing section 28 by the output of
The temperature control means 26 detects when the base 14 is removed, stores the temperature of the pace 14 immediately before that, and is set to notify the user after a time t2 calculated from the rate of temperature decrease of the base 14. When the temperature of the iron body 12f and pace 14 is high and the iron body 12f is removed from the placement part 28, the time t2 until the notification is longer is longer, and as the temperature at the time of removal is lower, the time t2 until the notification is Therefore, before the temperature of the pace 14 reaches a temperature at which water cannot be vaporized, it is possible to accurately notify the operator when to place the iron main body 12 on the stand 20. When the iron main body 12 is placed on the stand 20, the temperature control means 25 confirms that the device is in the state based on the output from the placement detection means 23, stops the notification, and starts supplying power.Ironing is performed as described above. Notifying means 27 when
This notifies the operator that the base temperature is decreasing, which prevents water from leaking out of the steam hole without being vaporized due to the low temperature of the base, and prevents the wrinkle smoothing effect from being lost. Since the notification stops when the iron body is placed on the placement part, it is easy to confirm that the iron has entered the power supply state, and an iron that is even easier to use can be realized.

Effects of the Invention As described above, the present invention uses a notification means to notify the user before the ironing temperature drops to such a point that the wrinkle smoothing effect cannot be achieved by ironing or water cannot evaporate and steam cannot be produced. In addition to notifying the user when it is time to place the main body on the stand, the above-mentioned notification also stops the notification when the iron main body is placed on the stand and the power is supplied to the stand, thereby making it easier to use when the base temperature is low. This prevents ironing and also eliminates the waste of placing the iron on the stand when it is not necessary, as well as making it easy and certain that the iron has entered the power supply state by stopping the notification. This has the effect of making ironing more efficient.
