Abstract

PURPOSE: To improve the efficiency of ironing work by informing user of the lowering of the temperature of a base during using and displaying that the temperature is equal to or lower than a fixed temperature at the time of placing an iron main body on a placing part. CONSTITUTION: In the state of placing the iron main body 12 on a stand 20, a temperature control means 25 inputs base temperature information from a temperature detecting means 17 and heats the base 14 to a set temperature by a heater 13. In the case of ironing by using steam, when a time t2 shorter than a time t1 until the temperature of the base 14 is lowered to a temperature where steam can not be generated passes, a reporting means 27 reports it. The time t2 is obtained by storing the temperature of the base 14 when the main body 12 is removed and converting it from a temperature lowering speed. In order to generate steam at the temperature of a base 14 at the time of resupplying power to the main body 12 by the stand 20, if the temperature is low, the means 25 reports this to a display part 28. In addition, power is supplied for the heater 13 until the temperature 14 is raised to the set temperature.

Description

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

2. Description of the Related Art Conventionally, as shown in FIG. 3, a cordless iron of this type includes a base 2 having a heater 1, a vaporizing chamber 3 provided on the base 2, a tank 4 disposed above the base 2, A thermostat 6 mounted on the base 2 and an iron main body 7 supporting a power supply terminal 6 connected to the heater 1.
The stand 11 was comprised of an electrode 8 connected to the power supply terminal 6, a power cord 9 connected to the electrode 8, and a stand 11 having a placing part 10 on which the iron main body 6 was placed.

Problems to be Solved by the Invention However, with such a structure, when the iron main body 7 is removed from the stand 11 and the iron main body 5 is not supplied with electricity, the temperature of the base 2 may change. Even if the water in the tank 4 is supplied to the vaporization chamber 3 as it gradually decreases, is it still water? The disadvantage was that the temperature in the trench dropped to a point where it could not be vaporized and turned into steam, and the water leaked out, causing the fabric to become soft. 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 status of the base 2 is not known, the iron body 7 is
Frequently placing the iron on the stand 11 significantly impairs the efficiency of ironing work.

Therefore, the present invention notifies the operator when the temperature of the base drops, informs the operator when it is time to place the iron body on the stand, and furthermore, if the base temperature is below a certain temperature when the iron body is placed on the stand, a display will be displayed. This is to inform the user of the condition, to prevent ironing when the base temperature is low, and to eliminate the waste of placing the iron body on the stand when it is not necessary.

Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
temperature detection means for detecting the temperature of the base; placement detection means for detecting whether or not the iron body is placed; and notification means for notifying when the base temperature drops during ironing;
The display part f which displays if the base temperature is below a certain temperature when the entire iron body is placed! r: Something to be provided.

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 generated, the temperature of the base gradually decreases, but the temperature is detected by the temperature detection means, so the temperature of the base is The notification means performs all notifications before the temperature reaches a point where steam cannot be generated. Furthermore, when the iron is placed on the stand, if the temperature of the base is below a certain level, the display will display the status and notify the operator of the need for power supply, preventing ironing after the base temperature has dropped. Furthermore, it is possible to eliminate the waste of unnecessarily placing the iron body on the stand.

Embodiment Hereinafter, one embodiment 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 vaporizing chamber 15 provided in the base 14, a tank 1e 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. Reference numeral 20 denotes a stand, which includes 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 main body 12 is placed on the stand 2o, the outputs of the temperature detection means 17 and the placement detection means 23 are input, and the temperature is set using the temperature setting button 24. a temperature control means 26 that heats the base 14'i to the temperature that has been set; a switching means 26 that is driven by the output of the temperature control means 26 and turns on/off the power supply to the heater 13; and a notification by the temperature control means 26. A notification means 27, a display section 28 using a light emitting diode, etc., and a placing section 2 on which the entire iron main body 12 is placed.
9, and a power cord 30 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 25 inputs the base temperature information from the temperature detection means 17 via 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
Heat 4.

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 20, and the iron is applied using steam. When the base 14 reaches a temperature at which water can be vaporized, the iron main body 12 is removed from the stand 2o. When the iron main body 12 is set to use steam, water passes from the tank 16 to the vaporization chamber 15, and the water is vaporized by the heat of the base 14, generating steam. This steam makes full use of the steam to do all the ironing.

However, when this steam is generated, the heat of vaporization is removed.
The temperature of the base 14 gradually decreases.

The temperature control means 26 sets the iron body 12 on the stand 2o.
A time t shorter than the time t1 from when the temperature of the base 14 drops to a temperature at which steam cannot be generated after removal from the base 14
2 has elapsed, the temperature control means 26 interlocks the notification means 27 to issue a notification. At the bottom of the groove described above, when the iron main body 12 is removed from the placement part 29, 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 temperature control means 25 detects when the iron body 12 is removed from the placement part 28 based on the output, and stores the temperature of the base 14 just before that time, and calculates the time n calculated from the rate of temperature decrease of the base 14. It is set to be notified after t2. In other words, when the iron body 12 is removed from the placement part 29 when the temperature of the base 14 is high, the time T2 until the notification is reached is long, and as the temperature at the time of removal is lower, the time t2 until the notification is reached is longer.
2 becomes gradually shorter. Therefore, it is possible to accurately notify the operator when it is time to sew the iron main body 12 onto the stand 20 before the temperature of the base 14 reaches a temperature at which water cannot be vaporized. Further, when the iron main body 12 is placed on the stand 2o, the temperature control means 25 confirms that the iron body 12 is in the placed state based on the output from the placement detection means 23, stops the notification, and starts power supply. Next, the operation when the base temperature decreases and the iron main body 12 is placed on the stand 20 will be described. Iron body 12 on stand 20
If the temperature control means 26 determines from the output of the temperature detection means 17 that the temperature of the base 14 is sufficient to generate all the steam when placing the base 14 on the base 14 and resupplying power, the temperature The detection means 26 opens and closes the switching means 26 to fully control the energization of the heater 13 and maintain the temperature of the base 14 at the set temperature. To generate electricity, if the temperature is low and constant T, the temperature control means 26 drives the display 28 to notify the operator of the need for power supply.At the same time, the temperature control means 26 controls the temperature of the base 14 The switching means 26 until the set temperature is reached.
1 to supply power to the heater 13. Further, if the temperature control means 26 determines that the base temperature has reached the set temperature, the display will be displayed.

The drive of the section 28 is stopped and the operator is informed that steam can be used. As described above, in order to notify the worker that the base temperature is decreasing by the notification means 27 and the display unit 28 while ironing, water does not evaporate due to the low temperature of the base and leaks out from the steam hole as it is. There is no longer a problem where the wrinkle smoothing effect cannot be obtained, and the usability is further improved.

Effects of the Invention As described above, the present invention provides notification by the notification means before the temperature of the base drops to such a level that the effect of ironing wrinkles cannot be obtained or water cannot evaporate, and the iron body is placed on the stand. By informing the operator of the timing and if the temperature is below a certain level when the iron is placed, the display notifies the operator of the need for power supply, which prevents ironing when the base temperature is low, and furthermore allows the iron to be placed on the stand. This has the effect of eliminating the waste of placing the iron on the iron when it is not necessary, and allowing efficient ironing.
