Description
[0001] The present invention relates to an apparatus for controlling standby power of an air conditioner, and more particularly, to an apparatus for controlling standby power of an air conditioner, more specifically, by switching a standby power mode and a normal operation mode by using a parallel contact switching unit, And more particularly to a standby power control apparatus for an air conditioner that is easy to maintain a switching circuit.
Generally, an air conditioner supplies cold air by compressing a refrigerant into a high-temperature and high-pressure gas and switching a refrigerant flow path to heat-exchange the refrigerant. Generally, the air conditioner is a household electric appliance with high power consumption, because it uses rotating equipment with high power consumption. In recent years, the power consumption of the air conditioner is reduced by using an inverter, and a circuit device for interrupting the standby power in the state that the power is off is inherent.
FIG. 1 illustrates a standby power control apparatus of a conventional air conditioner. 1, a

Korean Patent Laid-Open No. 10-2005-0055452 discloses a " standby power saving air conditioning system and its operation method ". The preceding document automatically controls the on / off state of the power switch for connecting or disconnecting the circuit between the power cord and the power source according to the driving state of the microcomputer. The prior art has a problem in that a power supply line of one of the input power supply lines is opened and closed, so that a small power consumption is generated even when the power supply switch is opened. Further, the on / off control of the power switch for performing the mechanical switching by the microcomputer does not solve the conventional problems as described above.
The present invention relates to an air conditioner of a new structure which can reduce the cost of a product by eliminating the use of an expensive magnetic switch by switching between a normal operation mode and a standby power mode by using a parallel contact switching unit and a photocoupler, And an object thereof is to provide a standby power control device.
An apparatus for controlling standby power of an air conditioner according to an embodiment of the present invention includes: a rectifying unit for receiving and rectifying three-phase power; A power factor improving unit connected to an output terminal of the rectifying unit to improve the power factor of the input power source by connecting an inductor L1 and a capacitor C1; And a first contact (CS1) provided between the rectifying part and the power factor improving part for switching the output of the rectifying part and a rush current blocking resistor (R1) connected in series to the first contact (CS1) And a second switching path comprising a switching path and a second contact CS2 connected in parallel to the first switching path to form a bypass path and to switch the output of the rectifying part on the bypass path, part; A light emitting diode (PC1-1) connected in parallel to the capacitor (C1) at an output terminal of the power factor improving unit and detecting an output power of the power factor improving unit (PC1-1); A power supply for receiving power from two phases of the three-phase power source to generate a signal power source; A phototransistor (PC1) which is provided in the input power line of the power supply and constitutes a photocoupler with the power detection LED (PC1-1) and is turned on by the light output of the power detection light emitting diode (PC1-1) -2); A remote control unit for transmitting a control signal for closing the first contact point CS1 according to a normal operation start signal of the air conditioner and transmitting a control signal for opening the first contact point CS1 according to a standby power cutoff signal of the air conditioner, controller; And a control unit which operates in response to power supply of the power supply and controls the second contact (CS2) to be opened by receiving a standby power cutoff signal from the remote controller while closing the second contact (CS2) .
The standby power control device of the air conditioner according to another embodiment of the present invention alternately generates the normal operation start signal and the standby power cutoff signal according to a toggle input of a power button provided to the remote controller.
According to the apparatus for controlling the standby power of the air conditioner of the present invention, the circuit is safely protected from the inrush current when switching to the normal operation mode by using the parallel contact switching unit and the photo coupler. In switching to the standby power mode, It is possible to prevent the consumption of standby power by shutting off the power supply. It is possible to reduce the cost of the product by excluding the use of the magnetic switch at the 3-phase power input terminal of the air conditioner and switch the mode by only the parallel contact control. There is no easy and mechanical wear and there is an effect that the life can be lengthened.
