Description

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

Conventionally, as shown in FIG. 3, a cordless iron of this type has a base 2 having a heater 1, a vaporization chamber 3 provided on the base 2, a tank 4 disposed above the base 2, and a base 2 having a heater 1. An iron main body 7 having a thermostat 5 mounted on a base 2 and 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 iron main body 7;
It consisted of a stand 11 equipped with a mounting section 10 on which the .

Problems to be Solved by the Invention However, with such a structure, the iron main body 7 is placed on the mounting portion 10 of the stand 11, and power is supplied to the heater 1 via the electrode 8 and the power supply terminal 6. Ironing is performed by raising the temperature of base 2, but if ironing is performed before base 2 reaches the temperature set by thermostat 5, wrinkles due to ironing will occur because the temperature of base 2 is low. No stretching effect is obtained. Furthermore, even when water is sent from the tank 4 to the vaporization chamber 3 for steam ironing, the water does not turn into steam and leaks out, causing fabric leakage.

Therefore, the present invention prevents ironing at low temperatures by notifying the user that the base temperature has not reached the set temperature when the iron body is removed from the stand's placement part before the base temperature reaches the set temperature. It is intended to do so.

Means for Solving the Problems In order to achieve the above objects, the present invention provides a base heated by a heater, a temperature detection means for electrically detecting the temperature of the base, a power supply terminal to the heater, and a temperature detection means. An iron main body having an output terminal, a removably placed iron main body, a power supply electrode connected to a power supply terminal, an input terminal connected to an output terminal of a temperature detection means, and a state in which the iron main body is placed. a placement detection means for detecting the
Controlling the energization of the heater based on the output signal of the temperature detection means that is linked to the output from the position detection means and input via the input terminal;
The stand includes a temperature control means that operates a notification means if there is no output from the position detection means when the base temperature is below a set value.

Effects The effects of this technical means are as follows.

In other words, if the iron body is removed from the stand resting part and ironing is performed before the base temperature reaches the set temperature, the temperature detection means will detect that the base temperature is lower than the set value. is detected, the notification means notifies the operator that the base temperature has not reached the set temperature and notifies the operator to place the iron body on the stand. This will prevent the iron from being used.

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

FIG. 1 shows an embodiment of the present invention. Reference numeral 12 denotes an iron body, which includes a base 14 having a heater 13 and a vaporizing chamber 1 provided in the base 14.
5, and a tank 1 disposed above the base 14.
6, a temperature detection means 17 for detecting the temperature of the base 14, a power supply terminal 18 connected to the heater 13, and an output terminal 19 for transmitting the output of the temperature detection means 17. 20 is a stand,
An electrode 21 connected to the power supply terminal 18, an input terminal 22 connected to the output terminal 19, a placement detection means 23 for detecting whether or not the iron main body 12 is placed on the stand 20, and a base 14. Temperature setting button 24 for setting or changing the desired temperature
, a notification means 25 such as a buzzer, a power cord 27 for supplying power to the equipment, a switching means 26 for turning on and off electricity to the heater 13 , the temperature detection means 17 , the position detection means 23 and the temperature detection means 25 . Temperature control means 28 receives the output from the setting button 24 to set the temperature of the base 14, opens and closes the switching means 26 to control the temperature, and drives the notification means, and a placing section 29 on which the iron main body 12 is placed. It is configured.

The operation of the above configuration will be explained based on the flowchart of the control procedure of the temperature control means 28 shown in FIG.
When the device is placed on the device 29 and the power cord 27 is connected to a household outlet, power is supplied to the device and the temperature control means 28 starts controlling. First, the temperature control means 28 goes through step 30 (hereinafter steps will be omitted).
), the output of the temperature setting button 24 is input, and the temperature of the base 14 is set. and temperature control means 2
8, in S31, the presence or absence of placement is determined based on the output of the placement detection means 23. Next, in step 32, the temperature control means 28 stops the notification if the notification means 25 is giving notification, and in step 34, the temperature control means 28 stops the notification.
is turned on, and the heater 13 is supplied with electric power via the power cord 27, the switching means 26, the electrode 21, and the power supply terminal 18 to heat the heater 13. Next, in S35, the temperature control means receives the output of the temperature detection means 17 via the input terminal 22 and the output terminal 19, compares the base temperature with the set temperature, and returns to step 31 if the set temperature has not been reached. . If the set temperature has not been reached
When returning to S31, if the iron main body 12 was removed from the placement part 29, the temperature control means 2
3, in S31, it is determined that there is no placement based on the output of the placement detection means 23, and in S33, the notification means 25 is driven to notify that it has not arrived. Unless the iron body 12 is placed
Repeat S31 and S33 to continue reporting non-arrival. Furthermore, even when the temperature is set without placing the iron main body 12 on the placing part 29, the temperature setting means 28 is
Repeat S31 and S33 to notify non-arrival. When the operator recognizes the non-arrival notification and places the iron main body 12 on the placement part 29, the heater 13 is energized and the temperature of the base 14 increases. When the temperature of the base 14 reaches the set temperature, the temperature control means 28 compares the base temperature and the set temperature in S35 and advances the control to S36. From now on, the temperature control means 28 is S36 and the base 1
4 is detected by the temperature detection means 17, and the temperature of the base 1 is detected by the temperature detection means 17.
The switching means 26 is opened and closed to control the electricity supply to the heater 14 so that the temperature of the heater 14 is maintained at the set temperature.

As described above, when the iron main body 12 is removed from the mounting portion 29 before the base temperature reaches the temperature set by the temperature setting means 28, the notifying means 25 notifies that the base temperature has not reached the temperature set by the temperature setting means 28. Therefore tank 1
Even when steam is used by passing water from the base 14 to the vaporization chamber 15, problems such as water leakage due to the low temperature of the base 14 and wrinkles not being smoothed due to the low temperature of the base can be prevented.

Effects of the Invention As described above, in the present invention, when the iron main body is removed from the mounting part before the base temperature reaches the set temperature, the notification means notifies the operator that the iron main body has not been reached, and the iron main body is placed on the stand. Since the main body is notified to be placed on the stand, it is possible to prevent ironing due to low temperatures and eliminate inconveniences such as water leakage from the steam hole and wrinkles in clothes not being smoothed out.
