Abstract

PURPOSE: To prevent ironing from being performed after the temperature lowers and to prevent water from leaking out from a base by providing a control circuit for informing operator of the state by a display part in the case that the temperature of the base becomes lower than a fixed temperature. CONSTITUTION: In the case of detaching the iron main body 1 from a stand 9 and performing ironing while generating steam, the temperature of the base 3 gradually lowers, the temperature is detected by a temperature detection means 6 and the control circuit 12 displays the decline of the temperature at the display part 11 at the time of mounting this iron 1 to the stand 9. In such a manner, by informing the operator of the need of feeding power, water leakage or the like due to ironing using the steam at a low temperature is prevented.

Description

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

BACKGROUND ART Conventionally, a cordless iron of this type has a base having a heater, a vaporization chamber provided on the base, a tank disposed above the base, and a temperature detection means for detecting the temperature of the base. An iron main body having a power supply terminal connected to the heater, an electrode connected to the power supply terminal and a display section using a light emitting diode, etc., controlling power supply to the heater and displaying a set temperature on the display section. It consisted of a stand with a control circuit to perform.

Problems to be Solved by the Invention However, with such a configuration, if the iron body is removed from the stand and used while producing steam without power being supplied to the iron body, the water in the tank will be supplied to the vaporization chamber. , steam is generated, but the heat of vaporization is taken away from the base, and the temperature of the base decreases. However, since the drop in temperature is not displayed, there is a problem in that when the temperature of the base reaches a point where the water supplied from the tank cannot be vaporized, the water supplied to the lower vaporization chamber leaks and wets the fabric. Furthermore, in order to prevent the temperature of the base from dropping, the iron itself had to be frequently placed on a stand, which was very inconvenient.

Therefore, in the present invention, when the temperature of the pace falls below a certain temperature, the condition is displayed on one display section, the user is informed that power supply is required, and ironing can be continued even after the temperature has decreased. This prevents water from leaking from the pace.

Means for solving the problems and technical means of the present invention for solving the above problems are as follows:
It is equipped with a control circuit that notifies you of the condition through a display when the pace drops below a certain temperature after reaching the set temperature.

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 pace gradually decreases, but the temperature is detected by the temperature detection means and the iron is placed on the stand. At times, the control circuit indicates on the display that the temperature is dropping and notifies the need for power supply, which prevents ironing while the temperature is dropping and eliminates water leakage from the pace.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Fig. 1, reference numeral 1 denotes the iron body, which includes a pace 3 having a heater 2, a vaporizing chamber 4 in which this pace 3 is installed, a tank 6 placed above the pace 2, a thermistor etc. that detects the temperature of the pace 3, etc. temperature detection means 6, a transmission terminal 7 for transmitting the output of this temperature detection means 6, and a heater 2.
It has a power supply terminal 8 connected to. Reference numeral 9 denotes a stand, which has an electrode 1o connected to the power supply terminal 8, a display section 11 using a light emitting diode, etc., processes the output from the temperature detection means 6, controls the temperature of the pace 3, and has a display section. 1
1, a setting button 13 for changing the set temperature of the control circuit 12, and the output of the temperature detection means 6 is sent to the transmission terminal 7) to the control circuit. It has a terminal 14 for sending temperature signals and a power cord 16 for supplying power to the entire device. Figure 2 shows a cordless iron where the display section 11 and setting button 13 of this device are arranged, and the display section using a light emitting diode etc. is turned off.
They are arranged in the order of low temperature → medium temperature → high temperature.

The operation of the above configuration will be explained with reference to FIG. First, when the power cord 16 is connected to an outlet while the iron body 1 is placed on the stand 9, the display section 11 displays an off state. Next, press the setting button 13 to set the control circuit 12 to adjust the temperature to a pace temperature that matches the fabric to be ironed.
Displays the set temperature. In this embodiment, the following explanation will be continued assuming that the maximum temperature is set. The display section 11 displays the maximum temperature. The control circuit 12 then controls the temperature signal terminal 1.
The base temperature and the set temperature are compared based on the output from the temperature detection means 6 obtained through the transmission terminal 7 and the base temperature, and the heater 2 is energized through the electrode 10 and the power supply terminal 8 until the pace 3 reaches the set temperature. I do. Further, as the temperature of the pace 3 increases, the control circuit 12 displays the current temperature of the pace 3 on the display section 11 together with the set temperature. If the current temperature of PACE 3 is low, the maximum temperature and low temperature are displayed, and as the temperature of PACE 3 increases, the current temperature display moves from low to high. Then, when the temperature of pace 3 reaches the maximum temperature of the set temperature, the display of the current temperature is stopped and only the set temperature is displayed.

Furthermore, the control circuit turns on and off the power supply to the heater 3 in order to maintain the temperature of the pace 3 at the set temperature. next,
When the iron main body 11 is removed from the stand 9 and ironed, the water in the tank 5 falls into the vaporization chamber 4 and the pace 3
It vaporizes due to the heat and comes out of the Pace 3 hole as steam. The steam and heat will smooth out the wrinkles in the fabric, but the temperature of the Pace 3 will be lower. In order to raise the temperature, the iron body 11 is placed on the stand 9 and power is supplied again.The control circuit 12 compares the output of the temperature detection means 6 with the set temperature and the base temperature, and if the base temperature is lower, power is supplied.

In this case, if the temperature of the pace 3 is below a certain temperature, which is too low to vaporize water, the control circuit 12 displays the current temperature on the display section 11 again, indicating that the base temperature is inappropriate for steam ironing. Therefore, the user is informed that power supply is necessary. Then, when the base temperature reaches the set temperature by power supply, the current temperature display will stop. Also, if the base temperature has not fallen below a certain temperature, the display section 11 will display only the set temperature as before,
The control circuit 12 performs power supply and temperature adjustment operations. Figure 3 is a flowchart showing the control procedure for the display.After that, even if the iron body 9 was attached to and detached from the stand many times during ironing operations, the base temperature remained below a certain temperature according to this control procedure. Since the current temperature is displayed when the iron is pressed, water leakage caused by ironing with steam at low temperatures can be prevented.

Effects of the Invention As described above, the present invention uses a display to notify the operator that the base temperature has fallen below a certain temperature, thereby preventing the worker from ironing while the base temperature has dropped. By leaking through the base without vaporizing, ironing can be done efficiently without getting the fabric wet, making it easier to use the layers.
