Embodiment Construction
[0026] The invention provides a standby power consumption control system of an outdoor unit of an air conditioner and an outdoor unit, which are suitable for an air conditioner system in which the internal and external units of the air conditioner adopt zero live wire communication, and the power supply of the indoor unit is obtained from the outdoor unit. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] Please also see image 3 and Figure 4 , The outdoor unit of the air conditioner provided by the present invention includes a wake-up module 110 , a power supply circuit module 120 , a switching power supply 130 and a control module 140 ....

The invention discloses a standby power consumption control system for an outdoor unit of an air conditioning chamber and the outdoor unit. The outdoor unit comprises a wake-up module, a power supply loop module, a switching power supply and a control module, wherein the wake-up module is used for transmitting a power source output by an indoor unit to the power supply loop module for charging; after charging voltage reaches starting voltage of the switching power supply, the switching power supply starts supplying power to the control module; the control module controls the wake-up module to disconnect and then controls the power supply loop to directly connect with an input power supply, and after being subjected to full-wave rectification by the power supply loop module, input alternating current supplies power to the switching power supply; the wake-up module is firstly disconnected and then the power supply loop module is controlled to connect with the input power supply, thereby avoiding interference on communication; by carrying out the full-wave rectification, the problem that the capacitance service life and work of the switching power supply are affected due to the fact that capacitance voltage fluctuation is relatively large by adopting half-wave rectification is solved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an outdoor unit standby power consumption control system of an air conditioner and the outdoor unit. Background technique [0002] How to reduce the standby power consumption of air conditioners is an important research and development direction in the field of air conditioners. It is easy to reduce the standby power consumption of the indoor unit, but the scheme for reducing the standby power consumption of the outdoor unit needs to be improved. At present, there are mainly two ways to reduce the standby power consumption of the outdoor unit. [0003] see figure 1 , which is a schematic diagram of an application embodiment of an existing air conditioner standby control system. When the air conditioner is in standby mode, the outdoor unit disconnects all power supplies through the relays (K1R, Ka, Kb), and the two external relays (K3R and K4R) connected to the transmi...
