Abstract

The invention discloses a standby circuit of a household appliance and a standby control method. The standby circuit of the household appliance comprises a 5V power dump circuit and a main control chip, wherein the 5V power dump circuit is arranged between a 5V load and a 5V power supply, and the main control chip is connected with the 5V power dump circuit and used for controlling the 5V power dump circuit to cut off power supplied to the 5V load when the main control chip receives a shutdown signal or a standby signal. By means of the standby circuit of the household appliance, the 5V power dump circuit is arranged between the 5V power supply and the 5V load, so that the 5V power supply only supplies power to the main control chip and other devices and does not supply power to other 5V loads when the household appliance is in a standby state, and therefore the energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a standby circuit and a standby control method of household appliances. Background technique [0002] In the prior art, the standby power consumption of household appliances is relatively high. According to a social survey on household standby energy consumption completed by the University of Oxford, the average household standby energy consumption accounts for 8% of the total electricity consumption. Therefore, reducing the standby power consumption of household electrical appliances is of great significance to energy saving and will bring huge economic benefits to the society. At present, household appliances usually use such as figure 1 Design scheme for low power standby as shown or as figure 2 The design scheme of low-power standby is shown. Such as figure 1 As shown, the standby circuit only includes one output power supply, and the feedback circuit of the switchin...
