Infrared control air-conditioner power-saving circuit

Abstract

The invention discloses an infrared control air-conditioner power-saving circuit which comprises an infrared ray signal receiving module, a control module and an output control module. The output control module receives and processes a signal sent by the infrared ray signal receiving module, and the control module controls power supply output of the output control module according to a processing result, is further connected with an infrared ray transmitting module and controls that the output control module outputs a power supply for an air conditioner and sends a startup signal to the air conditioner when receiving a startup remote control signal. The power supply is automatically cut off when the air conditioner is standby, an air conditioner power supply can be automatically turned on when the air conditioner is remotely controlled through convenient operation, and the energy consumption of air conditioner in the standby mode can be reduced to zero. A warning lamp is further connected between the output control module and the control module in series and gives out a warning signal with actions of the output control module, such as a startup signal, so that an operator is prompted to prevent misoperation.

Description

technical field [0001] The invention relates to an infrared-controlled air-conditioning power-regulating circuit. Background technique [0002] At present, due to the large power consumption of air conditioners, various forms of power savers for air conditioners have been produced, which mainly control the power supply of air conditioners to achieve the purpose of saving energy. Now there is a power saving circuit for air conditioners on the market. By cutting off the power supply when the air conditioner is turned off, the power consumption of the air conditioner in standby mode is saved. The working principle is: after the power is turned off, the current of the air conditioner is detected. When the presence of an infrared remote control signal is detected, the power supply will be connected, that is, the machine will be turned on. [0003] However, the above-mentioned air-conditioning power-conditioning circuit has the following disadvantages: if other electrical applian...

Problems solved by technology

[0003] However, the above-mentioned air-conditioning power-conditioning circuit has the following disadvantages: if other electrical appliances are constantly using the remote controller to emit infrared rays, then the air-conditioning power-converting circuit will continuously detect the infrared rays emitted by these other remote controllers, which will be seriously interfered and impact; when you want to turn on the air conditioner, you must detect infrared rays. When you press the "on" action, but it is too late to detect infrared rays, that is, there is no power. middle

But press the button again, it is in the off state again, but the infrared ray has been detected, that is, the power is turned on, but since the remote control is in the off state at this time, it is an invalid response, and the air conditioner can only be turned on by pressing the switch button again. , that is, the correct signal will be sent after pressing 3 times. This operation is very troublesome and affects the use, especially for older people, whose recognition ability is relatively poor, and it is very inconvenient to use
