Description

Power saving outlet device {a plug socket for saving power}

The present invention relates to a power-saving outlet device, and more particularly, to set and control the sensing mode and the driving mode of a plurality of single tap devices in a remote main device, and to provide standby power consumption of an electronic device connected to each single tap device. The present invention relates to a power-saving outlet device that directly measures reservation power consumption and determines whether a standby mode, a reservation mode, and a driving mode of a corresponding electronic product are determined using the measured standby power consumption and the reservation power consumption.

Among household appliances that are distributed in each household, there are products that need to be constantly powered (eg refrigerators, kimchi refrigerators), and products that do not need constant power sources (eg televisions, washing machines, computer systems, air conditioners, etc.). .

In the case of electronics that do not require constant power, it is sufficient to supply power only when the electronics are driven, but users are always plugging the electronics into an outlet. Standby power consumption is also consumed.

In addition, a computer system or a home theater system may be driven by several electronic products at the same time. In order to use the computer system or the home theater system, the user may have to turn on or off the power of several electronic products.

In other words, the computer system plugs peripherals such as the main body of the computer, the monitor and the printer into the outlet, and operates the power button separately provided in each electronic product (main unit, the monitor and the printer) only when the computer system is used. Turn on the power. However, when the user does not use the computer system, the placenta only turns off the power of the computer main body but does not turn off the power of the monitor device and the printer. In addition, in the case of the computer main body, the plug is left plugged into an outlet, so that a large amount of standby power is generated in each electronic product of the computer system, that is, the computer main body, the monitor unit, and the printer.

Similarly, in the home theater system, electronic devices such as a television, a DVD device, and a speaker are driven at the same time. In many cases, a user turns off only the TV and does not turn off the power of the DVD device and the speaker. By leaving the plug in the outlet, the standby power is generated in TVs, monitors and printers.

Even in the case of electronic products that do not require constant power, standby power is generated because the plug is constantly plugged into the outlet. Thus, standby power consumed in the standby mode of electronic products occupies 10% of the total power consumption. have. This is a national waste of power.

Various power-saving outlet devices have been proposed to reduce or eliminate power consumption due to standby power consumption.

However, most power-saving receptacle devices are not universal because their use is limited, and even though the standby power is different for each electronic product, when the set power value is reached, the power supply is unconditionally cut off. It may be blocked.

Among electronic products, washing machines, dishwashers, and rice cookers are electronic products that frequently use a reservation function. When the user sets the reservation function of the electronic device and the power supplied to the electronic device is cut off, all the reserved data is lost. Must be supplied. However, even in the reservation standby state, much power consumption does not occur as in the driving mode, and a little more power consumption occurs than the standby power consumption. Therefore, the conventional power saving type outlet device has a reservation standby state in which the user reserves the driving of electronic products. There is a risk that the power supply will be cut off.

The communication unit 15 may be a power line communication (PLC) device or a wireless communication device.

3 is a schematic functional block diagram of a single tap apparatus according to the present invention.

The single tap device includes a drive power generation unit 21, a control unit 22, a sensor unit 23, a communication unit 24, a storage unit 25, a drive switch 26, and a switching control unit 27. ), A current sensing unit 28, and a single sphere 29. The single sphere 28 is fitted with a plug of an electronic product. Typically, single tap devices are present in the corners that are invisible to people, making it difficult for users to unplug their electrical outlets when not in use. In the present invention, the sensor unit 23 and the drive switch 26 are connected in a long line or wirelessly so that the sensor unit 23 and the drive switch 26 can be separated from other components of the single tap device, so that the other components of the single tap device are inconspicuous corners. Even if the sensor unit 23 and the drive switch 26 can be installed on the front or side of the electronic product, the user can accurately detect whether the user is approaching the electronic product and the user can easily operate the drive switch 26. Make sure

The drive power generation unit 21 generates the drive power required for the single tap device 20 from the commercial power source and supplies it to each part of the single tap device 20. The driving power generation unit 21 receives a commercial AC power and converts it into a DC power for driving circuits of each unit.

The sensor unit 23 includes a human body sensor, an infrared sensor, and an RF reception sensor. The human body sensor detects the proximity of a person by detecting infrared rays emitted from the human body, and includes a band pass filter for increasing the reliability of the detected signal, an amplifying circuit, and an AD converter for converting an analog signal into a digital signal. . The infrared sensor is a sensor for detecting an infrared signal transmitted from an infrared remote controller, and transmits a certain carrier frequency at the time of transmission to increase the reliability of the detected signal. The receiving side receives a signal matching the preset carrier frequency as valid data. The RF reception sensor is composed of an RF reception antenna and a reception tuner device for detecting an RF signal transmitted from a transmitter.

The communication unit 24 performs communication between the main device and the single tap device, and may be a power line communication (PLC) device or a wireless communication device. The storage unit 25 stores a user set value (sensing mode and driving mode), a standby mode determination reference value, and a reservation mode determination reference value transmitted from the main device.

The switching controller 26 switches the commercial power applied to the single sphere 28 of the single tap device, and applies or cuts power to the electronic products connected to the single sphere 28. The switching control unit 26 may be configured as an SSR or a relay. The driving switch 26 is a mechanically driven switch, and the user may directly control the driving switch 26 to control the controller 22 to apply electric power to the electronic product.

The controller 22 sets the power application condition to the electronic device connected to the single sphere 29 according to the sensing mode set from the main device 10. That is, when the sensing mode is the human body detection, when the human body sensor detects the human body, power is applied to each sphere. When the sensing mode is the infrared remote control signal detection, the infrared sensor detects the infrared remote control signal to apply power to each sphere. When the sensing mode is the RF signal detection, when the RF receiving sensor detects a high frequency (RF) signal, power is applied to each sphere. If there is no sensing mode, power is applied to each sphere when the drive switch 26 is operated.

In addition, the controller 22 sets a power application condition to the electronic device connected to each sphere according to the driving mode set from the main device 10. If the driving mode is general, power is always applied to each sphere. When the driving mode is power saving, it is determined whether the electronic device connected to the single sphere 29 is in the standby mode, and when the electronic product is in the standby mode, the power applied to the single sphere 29 is cut off. If the driving mode is a reservation, the standby mode and the reservation mode of the electronic product are judged to be cut off in the standby mode, but in the reserve mode, the power is continuously supplied.

When the sensing mode is human body detection, the controller supplies power to the single sphere 29 when there is a person approaching the electronic product. If the electronic device is not driven and the standby mode is maintained for a predetermined time after the power supply, the control unit cuts off the power supply to the electronic product. However, the washing machine or dishwasher must be complicated before the user operates the electronic product. In the case of the washing machine, the laundry and the detergent are put in the washing conditions (bing, washing time, washing course, reservation, Rinsing frequency, water temperature, dehydration conditions) must be operated, and even in the dishwasher, dishes to be placed in the dishwasher must be put in the detergent and the dishwashing conditions must be operated. The power to the electronic product may be cut off while the work required for driving the washing machine and the dishwasher is performed. Therefore, even if the sensing mode is set to detect the human body, when the user operates the driving switch, the control unit may supply power to the electronic product.

In addition, the reservation power consumption when the user has set a washing machine or dishwasher reservation is much lower than the driving power consumption of the electronic products. At this time, if the driving mode is set to the reservation, the controller compares the power consumption of the electronic product with the standby mode determination reference value and the reservation mode determination reference value to determine whether to supply or block power to the electronic product.

The current sensing unit 28 measures the power consumption of the electronic products connected to each sphere, and includes a current sensing sensor, a band pass filter, a signal amplifier, and an AD converter. When the standby power consumption and the reservation power consumption information is requested from the main device 10, the current detection unit 28 measures the power consumption of the electronic products connected to the single sphere 29 to obtain standby power consumption and reservation power consumption information. To provide. In addition, when the single tap device is driven, the power consumption of the electronic device connected to the single sphere 29 is measured and provided to the controller 22. Then, the controller 22 determines whether the standby mode and the reservation mode of the electronic product from the power consumption. The current sensing unit 28 may measure power consumption for a predetermined period, obtain an average value thereof, and set the average value to standby power consumption, reservation power consumption, and power consumption of the electronic product.

The operation of the power saving type outlet device according to the present invention configured as described above will be described.

First, the assertion value sets the sensing mode, the driving mode, the standby mode determination reference value, and the reservation mode determination reference value of the plurality of single tap devices.

The main device 10 sets the sensing mode of the plurality of single tap devices 20 by directly inputting the sensing mode (human body detection / infrared remote control signal detection / RF signal detection / nothing) from the user through the input / output unit 13. There is a method of setting and receiving, and a method of setting an optimal sensing mode according to the type of the electronic product by receiving the type of the electronic product connected to the single tap device 20 from the user through the input / output unit 13.

In addition, the method of setting the driving mode of the plurality of single tap device 20 by the main device 10 includes a method of directly receiving a driving mode (general / power saving / reserving) from the user via the input / output unit 13, There is a method of selecting the type of electronic device connected to the single tap device 20 from the user through the input / output unit 13 and setting an optimal driving mode according to the type of the electronic product.

For example, in the case of the refrigerator, the sensing mode is set to none and the driving mode is set to general so that the refrigerator is constantly supplied with power.

In the case of a microwave oven or an air conditioner, the sensing mode is set to detect a human body and the driving mode is set to power saving, so that power is supplied to the electronic product when a person approaches the electronic product.

In the case of a washing machine, dishwasher, or rice cooker, the sensing mode is set to detect the human body and the driving mode is set to reservation so that when a person approaches the electronic device, power is supplied to the electronic product, even if no one is near. Allow the power to be supplied while the appliance is operating in the reserved mode.

Next, the claim value requests the standby power consumption and the reserved power consumption information from each single tap device 20 to obtain the standby power consumption and the reservation power consumption information of the electronic device connected to the single tap device 20. Then, the current sensing unit 28 of the single tap device 20 measures the power consumption of the electronic product. At this time, since the main device 10 and the single tap device 20 do not know whether the corresponding electronic product is in the standby mode or the reservation mode, the user guides the electronic product to maintain the standby mode or the reservation mode.

When the standby power consumption information is received from the single tap device 20, the main device 10 sets the standby mode determination reference value using the standby power consumption received from the single tap device 20. However, when the standby power consumption is measured to set the standby mode determination reference value, if the corresponding electronic product is not in the standby mode, the measured standby power consumption may be high or low. If the measured standby power consumption is higher than the upper threshold value or lower than the lower threshold value, an error is generated and the standby power consumption of the electronic product is measured again. In addition, the reservation mode determination reference value is set using the reserved power consumption received from the single tap device 20. If the received power consumption is equal to or lower than the standby power consumption, it is recognized as an error and is reserved for the consumption of the electronic product. Measure power again.

The asserted value stores the sensing mode, the driving mode, the standby mode determination reference value, and the reservation mode determination reference value for each single tap device, and delivers them to the single tap device.

The single tap device 20 receives the sensing mode, the driving mode, the standby mode determination reference value, the reservation mode determination reference value set by the user from the main device 10, and stores the received value in the storage unit 25. Accordingly, the electric power to the electronic device connected to the single sphere 29 is applied or cut off.

If there is no sensing mode and the driving mode is normal, the single tap device is driven in the same manner as the general single tap device, and power is continuously supplied to all the spheres of the single tap device.

If there is no sensing mode, power is supplied to all the spheres of the single tap device only when the user operates the drive switch.

In the case of electronic products, such as a washing machine, a dishwasher, and an electric rice cooker, in which a user accesses and operates the electronic product, and a reservation function is used, the sensing mode is set to human detection and the driving mode is set to reservation.

At this time, if the human body sensor of the sensor unit 23 detects the human body or the drive switch 26 is pressed, the control unit 22 to operate the switching control unit 27 so that power is supplied to the single sphere (29). The current sensing unit 28 continuously monitors the power consumption of the electronic device connected to the single sphere 29.

If the electronic device is not driven and maintains the standby mode for a predetermined time, the controller 22 operates the switching controller 27 to cut off the power supplied to the single sphere 29.

Even if the electronics are not driven, if the reservation mode is maintained, the control unit 22 continuously supplies power to the single sphere 29.

When the electronic product is driven and is switched to the standby mode, the controller 22 operates the switching controller 27 to cut off the power supplied to the single sphere 29.

By doing so, when the user approaches the electronic product to do other work, even when the human body is detected, the standby power consumption can be reduced by cutting off the power supplied to the electronic product. In addition, even when the power supplied to the electronic product is cut off while the user performs the work necessary for driving the electronic product, the user may operate the driving switch to supply power to the electronic product. In addition, standby power and reservation power consumption are measured to determine the standby mode and reservation mode of electronic products based on the measured values. In the mode, power is supplied to enable driving according to a reservation set by a user.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only for describing the best embodiment of the present invention and not for limiting the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
