Description

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

Prior Art A conventional iron using an electronic circuit was as shown in Fig. 3.

In other words, when the power cord 1 is plugged into an outlet, the heating element is not energized, and the display means 2 indicating the temperature setting position is illuminated at the "off" position. The temperature is set to "low" and "medium" by the user operating the temperature setting means 3 once at a time.

It can be switched to "high" in sequence, and from "high" it returns to "off" again. Also, if you leave the iron unattended, for example, with the temperature setting set to "high" and a visitor or telephone is left unattended, the power to the heater will be cut off after a certain period of time.
The temperature setting also returned to "off".

Problems to be Solved by the Invention However, in such a configuration, when the iron that has been turned off due to neglect is to be used again, the temperature setting means 3 must be set several times in order to set the temperature setting to "high" again. There was the inconvenience of having to operate it multiple times.

Means for Solving the Problem The technical means of the present invention for solving the above problem is that when an iron that has been turned off due to neglect is to be used again, by operating the temperature setting means 3 once, This will return the temperature to the setting before leaving it.

For production The effect of technical means is as follows.

In other words, if the user sets the temperature to "high" and leaves the iron unattended while the iron is being ironed due to a visitor or a phone call, etc., the forget-to-turn-off timer will operate after a certain period of time and the power to the heater will be cut off and the temperature will rise. The setting is set to "off". If the user wants to continue ironing again, by operating the temperature setting means once, an electronic control circuit using a microcomputer etc. will adjust the set temperature before leaving the iron on.
In other words, it is reset to "high".

As a result, the user can easily obtain the temperature setting when the heater is shut off due to the iron being left unattended.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 and 2, 4 is a base in which a heater 6 is embedded, and 6 is a bar provided above this base 4.

A control circuit 7 compares and processes the temperature set by the temperature setting means 8 and the output of the temperature sensor 15 attached to the base 4 using the microcomputer 9. 1o is a display means consisting of an LED or the like that indicates the set temperature, and normally lights up to display each stage from "off", which does not energize the heater 5, to "high", when the base temperature is approximately 200'C. do. Reference numeral 11 denotes a notification means such as a buzzer, which normally emits several electronic sounds when the temperature of the base 4 reaches a set temperature and becomes usable. Reference numeral 12 denotes a state determining means for determining whether the iron is in a stationary state or in motion. When the iron is left in a stationary state for a certain period of time or more, the control circuit 7 cuts off the power to the heater 5 in response to this signal. 13 is a power cord that supplies power to the heater 5 and the control circuit 7.

The microcomputer 9 mentioned above will now be described in detail. This microcomputer 9 has state determining means 12
If the stationary state continues for a certain period of time or more, the power supply to the heater 6 is cut off, and at the same time, the temperature setting display means 10 is turned off. Then, the temperature setting information immediately before the power supply to the heater 5 is cut off is stored, and when the temperature setting means 8 is operated again after the power supply is cut off, the stored temperature position is set at the first operation. It is programmed to set the temperature.

Next, the operation of the configuration of this embodiment will be explained.

First, when ironing is to be carried out, the temperature is set to an arbitrary temperature, for example "high", using the temperature setting means 8 to start energizing the heater 5, and the temperature of the base 4 begins to rise. From then on, the control circuit 7 controls the temperature sensor 14.
The temperature of the base 4 is detected by the output of the temperature setting means 8, and in order to maintain the temperature of the base 4 within the high temperature range set by the temperature setting means 8, the power supply to the heater 6 is controlled by electromagnetic switching AG, etc. This allows the user to iron the clothes.

During the ironing process, for example, due to a visitor or a phone call, the ironing process was temporarily interrupted and the iron was left unattended.
After a predetermined period of time has elapsed, the microcomputer 9 cuts off the power to the heater 5 and the temperature setting is turned off.

Then, when the user finishes his work and starts ironing again, by operating the temperature setting means once, the set elasticity changes from "off" to "high" which was set before work was interrupted. You can continue working.

Effects of the Invention As described above, the present invention provides an iron that can be used again even after the iron has been left in a stationary state for a certain period of time, the power to the heater has been cut off, and the temperature setting has also been turned off.
A microcomputer or the like stores the temperature setting before the heater is turned off, and the temperature can be reset to this temperature by just one operation of the temperature setting means, greatly improving usability.

Claims (1)

[Claims] A base having a heater, a temperature setting means for arbitrarily setting the temperature of the base, a state determining means for determining whether the iron is in use or stationary, and a signal from the state determining means to cause the iron to stand still for a certain period of time. If the temperature setting means is operated again after cutting off the electricity supply to the heater, the control circuit shuts off the electricity supply to the heater in the first operation. An iron that allows you to select the set temperature before power is cut off.
