Abstract

The present invention is to install an energy-saving electric iron that can improve the safety and reduce the use of electric energy by installing two additional switches that can control the power supply to the commonly used household electric iron.

Description

Electric iron for energy saving

Commonly used household electric iron is composed of a temperature controller for supplying electricity to the electric plug, and adjusts the temperature of the ironing hot plate according to the object to be ironed. Since the temperature is controlled by only one thermostat, if the iron is placed on the iron while ironing, there is a risk of fire, and even if it is standing using the rear panel, power is continuously supplied and wastes power.

In the present invention, by installing the handle switch of the handle portion and the back plate switch of the back plate portion technology for controlling the power supplied to the iron.

1 is an energy-saving electric iron proposed in the present invention, Figure 2 is a schematic diagram of an electric iron used in the prior art. The size of the knob switch and the rear panel switch can vary depending on the characteristics and shape of the product.

As shown in FIG. 1, the electric iron proposed in the present invention is to use a knob switch and a back plate switch to the existing electric iron shown in FIG. 2. Table 1 shows the state of the power supply according to the operation of the knob switch and the rear panel switch.

Knob switch Backplane switch Power supply On On A% On Off 100% Off On B% Off Off 0%

In Table 1, On indicates that the switch is pressed and Off indicates that the switch is not pressed. As shown in Table 1, the power consumption varies according to the on and off states of the knob switch and the rear panel switch. In this case, 100% of power means power required for the temperature set in the temperature controller. Only when the knob switch is turned on and the rear panel switch is turned off, 100% of the power is supplied. This state corresponds to a state where the iron is placed on an iron to be ironed. The knob switch is turned on and the rear panel switch is turned on when the knob switch is held by a person for ironing while the electric iron is upright using the rear panel. Prevent waste. In addition, when the knob switch is off and the back plate switch is on, it corresponds to the state where the electric iron is erected using the back plate of the iron during ironing, and in this case, only B% of power is supplied to reduce the waste of power. . Lastly, when both the knob switch and the rear panel switch are turned off, the iron switch is placed on the ironing object and the person does not grasp the knob switch, and it is not only a waste of power but also prevents overheating of the heating plate to prevent safety. Power supply is cut off to improve.

Coil springs or leaf springs can be used to ensure that the knob and rear panel switches are automatically in the off position when no human gripping or weighting of the iron is applied.

Here, A% and B% are numbers of 0% or more and 100% or less, and when the iron is standing up using the back plate of the electric iron or when a person grips the handle switch for ironing while standing, the power supply is turned off. It means you can shut it down and provide some power. If the back panel switch is turned off and the power supply is turned off, then when you want to iron again, it is considered when the hot plate may need a lot of power to heat up to the temperature required for ironing.

In addition, by adding a timer function to the rear panel switch, when the rear panel switch is turned on, the power supply is gradually reduced from 100% to 0% as time passes, thereby reducing the waste of power.

By additionally installing two switches in the existing electric iron, it is possible to achieve safety in use and reduction of power energy.

Claims (4)
