Description

Surface-mount device for saving electric power of home appliances}

The present invention relates to an external power saving device for home appliances, and more particularly, to an external power saving device for home appliances that can be used to easily connect to the power supply of all home appliances to save electricity wasted at home.

As a general electric saving method, air conditioners are used with fans with windows and doors closed and curtains or blinds protected from direct sunlight, while fans are kept open and at a distance from the windy side. Circulate, the refrigerator cools hot foods and arranges them at appropriate intervals to circulate cold air, reduces the number of door openings and closings, the washing machine collects the laundry and puts them all together, and the washing time does not exceed 10 minutes. The common knowledge of power saving such as turning off lights in empty rooms is known.

Selecting energy-efficient products for home appliances, replacing the lighting fixtures with power savings, and using a switch type with a switch for the power supply are hardware saving measures. In industries with high electricity consumption, various power control power saving devices may be purchased separately.

However, the above power saving common sense is often not practiced in real life in most homes, and particularly, it is difficult to expect effective power saving in a situation in which a TV, a PC, etc. are habitually turned on. In case of purchasing a power-saving device or replacing an existing home appliance, there is a disadvantage in that a cost is required.

Accordingly, the present invention focuses on the above points, and can be easily connected to the power supply of all home appliances, and automatically cuts off the power when no activity is detected for a certain time, thereby efficiently saving electricity wasted at home. It is an object of the present invention to provide an external power saving device for home appliances.

When stopped above, the timer unit 36 is output to the driving unit 40.

The detection unit 20 may further include an illuminance control unit 38 so as to change a set time of the timer unit 36 in association with an indoor lighting device.

The body 10 may further include a clamp 16 for attaching and detaching on the home appliance.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

1 is a perspective view showing a power saving mechanism according to the present invention, Figure 2 is a block diagram showing the main circuit connection of the power saving mechanism according to the present invention.

The present invention includes a body 10, a detection unit 20, a substrate 30, and a drive unit 40 in an integrated configuration in a mechanism that is detached from the power supply unit of the home appliance to control the power supply. Although FIG. 1 illustrates a three-prong outlet (also called a multi-tap), the same can be applied to a multi-prong outlet such as two-hole, four-hole, five-hole outlet, and the like.

The body 10 of the present invention includes terminal blocks 12 and 14 for relaying power. At least one input terminal block 12 and one or more output terminal blocks 14 are configured in the body 10. The input terminal block 12 is a part coupled to the power supply side, and the output terminal block 14 is a part connected to the home appliance which is the load side.

The detection unit 20 of the present invention is installed on the front of the body 10 to generate a signal linked to the movement of a person. Human movement is detected by the heat of the human body, and in this case, an infrared sensor can be used, which is classified into a quantum type and a thermal type. The electrons use photodiodes or photoconductive elements and use the electromotive force and the change in conductivity caused by the electrons excited by the incident light energy. The latter uses pyroelectric infrared sensors or thermopiles and uses temperature changes due to absorption of infrared energy based on radiation from black objects. Although both forms differ in sensitivity, responsiveness, wavelength dependence, etc., any of the above-described forms may be used for the detection unit 20 of the present invention.

The drive unit 40 of the present invention is installed inside the body 10 to intercept the connection of the terminal block 12,14. The driving unit 40 uses a relay driven by a DC power supply, and a contact capacity of about 15A is appropriate. The power of the input terminal block 12 is interrupted to the output terminal block 14 in accordance with the on-off state of the drive unit 40. The interruption of the power source according to the operation of the driving unit 40 refers to the substrate 30 (FIG. 2) described later.

The substrate 30 of the present invention is mounted inside the body 10 with the detector 20 and the driver 40 at the input and output ends, and detects a change in the input signal of the detector 20 to drive the driver 40. Adjust the operating time of). The detection unit 20 includes an infrared sensor installed in the body 10 and a circuit for processing a signal therefrom. The substrate 30 is installed in a position where it does not interfere with the detector 20 and the driver 40 and is interconnected in a circuit.

In FIG. 2, the substrate 30 of the present invention includes a DC power supply unit 32 for generating a DC power supply from the input terminal block 12, an amplifying unit 34 for amplifying a signal of the detection unit 20, and the amplified signal. The timer unit 36 is output to the driving unit 40 when the input of the signal is interrupted for more than a predetermined time. The DC power supply unit 32 is composed of a rectifier circuit, and the amplifier 34 is composed of an amplifier circuit in which an OP amplifier is used. The timer unit 36 may use a timer relay in the simplest form, and a timer / counter IC and a microprocessor may be used for more complicated control.

In operation, a signal is generated from the detector 20 while a person (user) is active when the body 10 is inserted into the wall outlet and connected to the power source of the household appliance to operate the household appliance. When the user is away from the home appliance (for example, a warm air heater), the signal is not generated from the detector 20, and accordingly, the timer 36 operates to start counting time. When the set time has elapsed, a signal is output to the driving unit 40 so that the contact point 40a is opened and the power supply of the input terminal block 12 is short-circuited without communicating with the output terminal block 14. Therefore, unnecessary electricity consumption of home appliances is prevented, and fire caused by heating of the heater is also prevented.

At this time, the detection unit 20 further includes an illuminance control unit 38 to vary the set time of the timer unit 36 in association with a lighting device in the room. Illumination control unit 38 is a circuit for implementing various operations depending on whether the indoor lighting is on or off. As an example, when the user goes to bed at night and forgets to use the home appliance, the illuminance control unit 38 may shorten the setting time of the timer unit 36 so that the power is quickly turned off. As another example, when the illuminance of the room is greater than or equal to a predetermined value, the operation of the timer unit 36 may be stopped to maintain the contact 40a of the driving unit 40 in a normal cloth state.

Types with separate on / off switches are available on the market. Applying the configuration of the present invention to such a multi-tap can be used in three modes of manual on-off mode and automatic mode.

3 is a perspective view showing a power saving mechanism according to a modification of the present invention.

The body 10 'according to a modification of the present invention may further include a clamp 16 for attaching and detaching on a home appliance. In the figure, a state (10) is mounted with a clamp (16) to a support of a fan-type hot air heater. The configuration and operation of the detector 20, the substrate 30, and the driver 40 provided in the body 10 'are the same as those of FIG. 1 described above. The clamp 16 adopts a configuration using a band and a screw so as to be tightly fixed by loosening the band and tightening the screw regardless of the size of the mounting object.

At this time, if the input terminal block 12 of FIG. 1 is a plug having a protruding terminal pin, all of FIG. 3 may have the same outlet shape as the output terminal block 14. The body (10 ＇) and the wall outlet 50 is connected to a separate wire, the power line of the home appliance is directly connected to the body (10＇).

In Figures 1 to 3 because the mechanism according to the configuration of the present invention is not embedded in the home appliances, and separated into an external type, it is possible to operate several household appliances of different types as needed.
