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, this type of cordless iron has a base 2 having a heater 1, a thermostat 3 mounted on the base 2, and a setting for changing the temperature setting of the thermostat 3. A dial 4, an iron body 6 having a power supply terminal 5 electrically connected to the heater 1, and the power supply terminal 5.
It consisted of an electrode 7 connected to the iron body, a power cord 8 connected to the electrode 7, and a stand 10 provided with a placement part 9 on which the iron body 6 is placed.

Problems to be Solved by the Invention However, with such a structure, even if the iron body 6 is removed from the stand 10 and ironing is performed without power being supplied, the temperature setting dial 4 of the thermostat 3 cannot be turned. Because it is possible to change the temperature setting, even if you set the temperature to suit each fabric, it is possible to accidentally press the setting dial 4 while ironing.
Touching the iron could cause the temperature to be set unsuitably for the fabric, damaging the fabric or cutting off the electricity, significantly impairing ironing efficiency.

Therefore, the present invention makes it possible to set the temperature of the base only when the iron body is placed on the stand, thereby preventing the temperature from being set incorrectly during ironing, and ensuring that the temperature is always suitable for the fabric. This allows you to iron your clothes with the iron.

Means for Solving the Problems Technical means of the present invention for solving the above problems include a base heated by a heater, a temperature detection means for electrically detecting the temperature of the base, and a power supply to the heater. An iron body having a terminal and an output terminal of a temperature detection means, an iron body on which the iron body is removably placed, a power supply electrode connected to a power supply terminal, an input terminal connected to an output terminal of the temperature detection means, and an iron. A placement detection means for detecting the placement state of the main body, a temperature control means for controlling energization to the heater based on an output signal of the temperature detection means inputted through the input terminal, and the above-mentioned placement detection means, The stand includes a temperature setting means that changes the set temperature of the temperature control means when the placement detection means detects the placement of the iron main body.

Effects The effects of this technical means are as follows.

That is, when the iron body is on the stand, the placement detection means detects it and the temperature control means can freely set the temperature, but when the iron body is not on the stand, the placement detection means detects it and the temperature control means can set the temperature freely. This prevents a decrease in work efficiency and damage to the fabric due to unexpected temperature setting changes during ironing.

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

In FIG. 1, reference numeral 20 denotes an iron body, which includes a base 22 having a heater 21, and a temperature detection means 23 such as a thermistor for detecting the temperature of this base 22.
, an output terminal 24 for outputting temperature information from the temperature detection means 23 , and a power supply terminal 25 connected to the heater 21 . 26 is a stand, and a placing part 27 on which the iron main body 20 is placed.
, a placement detection means 28 for detecting whether or not the iron main body 20 is placed; an electrode 29 electrically connected to the power supply terminal 25; and an input terminal for inputting temperature information output from the output terminal 24. 30, a temperature control means 32 using an electronic circuit or the like that controls the energization of the heater 21 so that the temperature is set by the output from the temperature setting means 31 using a tact switch or the like, and this temperature control means A display section 33 using an LED or the like that displays the set temperature of 32;
It has a power cord 34.

FIG. 2 shows an example of the arrangement of the display section 33 and the temperature setting means 31, and the display section 33 can display an off state and six setting states from low to high.

To explain the operation in the above configuration, first, when the iron body 20 is placed on the placement part 27 of the stand 26, the placement detection means 28 detects that the iron body 20 is placed on the temperature control means 32.
Output to. When the iron main body 20 is in the placed state, the temperature setting means 32 receives input from the temperature setting means 31. When the temperature of the base 22 is set by the temperature setting means 31, the temperature control means 32 inputs the temperature information of the base from the temperature detection means 23 through the output terminal 24 and the input terminal 30, and the temperature of the base 22 is adjusted. The heater 21 is energized via the electrode 29 and the power supply terminal 25 until the set temperature is reached, and after reaching the set temperature, the heater 2
1 is turned on and off to maintain the set temperature. Also, at this time, the display section 33 is displaying the set temperature. After reaching the set temperature, remove the iron main body 20 from the mounting part 27 of the stand 26 and remove the iron main body 20 when ironing is being performed.
The placement detection means 28 detects that the temperature control means 32 is not placed. When the iron body 20 is not placed, the temperature control means 32
does not accept input from the temperature setting means 31, and no matter how much the temperature setting means 31 tries to change the temperature setting, the temperature control means 32 maintains the set temperature before removing the iron main body 20, and the display section 33
continues to display the temperature. In order to supply power again, place the iron main body 20 on the mounting part 2 of the stand 26.
7, the temperature control means 32 receives input from the temperature setting means 31 and can freely change the set temperature. In addition, by providing the display section 33 on the stand 26 as shown in FIG. 2 and arranging it in front of the mounting section 27, the set temperature can be easily confirmed from the display section 33.

Effects of the Invention As described above, the present invention makes it possible to set the temperature only when the iron body is placed on the placement part of the stand, and ironing can be done by removing the iron body from the placement part. This prevents the temperature setting from being changed unexpectedly when the iron is on, and also prevents accidents such as turning off the power to the iron or damaging the fabric due to incorrect settings.
