Embodiment 1

[0056] The embodiment of the present application provides a power control method, figure 1 It is a schematic flow chart of the power control method in the embodiment of the present application, such as figure 1 As shown, the power control method is applied to household appliances, which at least include air conditioners.

[0057] Specific steps can include:

[0058] Step 101: When the subsequent control module is in the standby state, the standby wake-up module receives a standby wake-up instruction, responds to the standby wake-up instruction, and generates a first control signal;

[0059] It should be noted that the subsequent control module is the main control module of the household appliance, and is used to control the working state (including the running state and the standby state) of the household appliance. Here, the subsequent control module is in a standby state, that is, the household appliance is in a standby state.

[0060] Exemplarily, by pressing the power-o...

Embodiment 2

[0084] Based on the first embodiment above, the present application provides a power control circuit, figure 2 It is a schematic diagram of the first component structure of the power control circuit in the embodiment of the present application. Such as figure 2 As shown, the power control circuit mainly includes: a main power supply module 201 , a power supply switch module 202 , a subsequent control module 203 and a standby wake-up module 205 .

[0085] The second input terminal of the power supply switch module 202 is connected with the main power supply module 201; The output end is connected, and is also connected to the output end of the standby wake-up module 205; the main power supply module 201 is used to supply power to the subsequent control module 203 through the power supply switch module 202;

[0086] When the subsequent control module 203 is in the standby state, the power supply switch module 202 receives the first control signal sent by the standby wake-up ...

Embodiment 3

[0096] Based on the second embodiment above, the present application provides a power control circuit, image 3 It is a schematic diagram of the second composition and structure of the power control circuit in the embodiment of the present application.

[0097] Such as image 3 As shown, the power control circuit includes a main power supply module, a power supply switch module, and a post-stage control module ( image 3 Not shown in , one port is the P port, the other port is the MCU-OFF port), the second control module and the standby wake-up module (including the auxiliary power supply module and the first control module).

[0098] The power supply switch module includes: a second switch device (such as a relay RL) and a forward diode D3. The specific connection method is: the second input end of RL (i.e. the second input end of the power supply switch module) is connected to the output end of the main power supply module, and the output end of RL (i.e. the output end of ...

Abstract

The invention discloses a power control method, a power control circuit, a power control device and a household electrical appliance, and the method comprises the steps: a rear-stage control module is in a standby state, a standby wake-up module receives a standby wake-up instruction, and by responding to the standby wake-up instruction, a first control signal is generated; a power supply switch module is triggered to be in a closed state according to the first control signal so as to control the main power supply module to supply power to the rear-stage control module, and the rear-stage control module is awakened from a standby state to an operation state; the rear-stage control module is switched from the running state to the standby state and generates a second control signal; and the power supply switch module is triggered to be in an off state according to the second control signal to control the power supply circuit between the main power supply module and the rear-stage control module to be disconnected. Therefore, when the rear-stage control module is in the standby state, the power supply circuit between the main power supply module and the rear-stage control module is disconnected, and the main power supply module cannot supply power to the rear-stage control module, that is, the rear-stage control module is in the standby state in the power-off state, so that the power consumption is reduced.

Description

technical field [0001] The present application relates to power control technology, in particular to a power control method, a power control circuit, a device, and a household appliance. Background technique [0002] After the integrated air conditioner on the market is connected to the mains, the electronic control system it carries is on standby in the charged state, so that the air conditioner will continue to consume power in the standby state. Contents of the invention [0003] In order to solve the above technical problems, the present application provides a power control method, a power control circuit, a device, and a household appliance. [0004] The technical scheme of the present application is realized like this: [0005] In a first aspect, a power control method is provided, the method comprising: [0006] When the subsequent control module is in the standby state, the standby wake-up module receives the standby wake-up instruction and responds to the standb...
