In order to solve the technical problem of high standby power consumption of the household appliance 100, a solution may be to find a lower MCU chip for standby power consumption. However, the workload of replacing the MCU software update is huge, and the reliability verification also requires a long time. Meanwhile, in the standby state, although the lower MCU chip using power consumption can reduce the standby power consumption, the power consumed by the MCU in the standby process still exists, which cannot solve the technical problem of higher standby power consumption of the household appliance 100.

The following is further described with reference to the accompanying drawings.
Referring to fig. 1, the home appliance 100 includes a main control panel 10, a display panel 20, and a power key 30 or a wake-up key 40.
The main control board 10 includes a main power supply. The main power supply is used for outputting a main power supply voltage V of 17VMTo supply power to the first power conversion chip 1 and the second power conversion chip 2. The first power conversion chip 1 is used for converting a main power voltage V of 17VMConverting into a first supply voltage V1 of 5V, and a second power conversion chip 2 for converting a main supply voltage V of 17VMTo a second supply voltage V2 of 5V. In other embodiments, the main power supply may be independent of the main control board 10, and the commercial power accessed by the household appliance 100 is directly converted by a transformer.
The display panel 20 includes a first power conversion chip 1, a second power conversion chip 2, a standby circuit 3, and a load circuit 4.
The first power conversion chip 1 may be a linear power conversion chip. In a specific example, the first power conversion chip 1 may be an LDO (Low Dropout linear Regulator) for outputting a voltage of 5V to power the standby circuit 3.
The second power conversion chip 2 may be a switching power conversion chip. In a specific example, the second power conversion chip 2 may be a DCDC chip (direct current to direct current power conversion chip) for outputting a voltage of 5V to power the load circuit 4.
The standby circuit 3 remains in operation when the household appliance 100 is in a standby state.
Referring to fig. 2, the standby circuit 3 includes a first wake-up circuit 31, a second wake-up circuit 32, a first wake-up circuit 33, and an inverter 34. The standby circuit 3 is simple and stable to control, has fewer components and small consumed power, and is beneficial to reducing the standby power consumption of the household appliance 100.
The first wake-up circuit 31 is configured to receive a first wake-up signal generated by pressing the power key 30 or the wake-up key 40 of the household appliance 100 to generate and output an enable signal. Therefore, the first wake-up signal can be generated by pressing the power key 30 or the wake-up key 40 of the household appliance 100, so that the standby circuit 3 generates an enable signal after receiving the first wake-up signal through the first wake-up circuit 31, and enables the second power conversion chip 2, so that the second power conversion chip 2 is awakened to work, thereby recovering power supply to the load circuit 4, and realizing switching from the standby state to the load operation state. The first wake-up circuit may include a PNP transistor having a base for receiving the first wake-up signal generated by the power button 30 or the wake-up button 40 being pressed.
The second wake-up circuit 32 is configured to receive a second wake-up signal to generate and output an enable signal, where the second wake-up signal is generated by the main control board 10. Therefore, the main control board can generate the first wake-up signal to send a wake-up instruction to the display panel, so that the standby circuit 3 generates an enable signal after receiving the second wake-up signal through the second wake-up circuit 32, and enables the second power conversion chip 2, so that the second power conversion chip 2 is awakened to work, power supply to the load circuit 4 is recovered, and switching from the standby state to the load operation state is achieved.
The third wake-up circuit 33 is configured to receive a third wake-up signal to generate and output an enable signal, wherein the third wake-up signal is generated by the panel control circuit 41. The display panel control circuit 41 includes a display panel 20 control chip. The display panel control chip can continuously detect the first wake-up signal and/or the second wake-up signal when in a working state, and generates a third wake-up signal when detecting the first wake-up signal and/or the second wake-up signal. The first wake-up circuit may include an NPN transistor having a base for receiving the third wake-up signal.
In particular, the first wake-up signal and the second wake-up signal may be pulsed signals. When the first wake-up signal or the second wake-up signal is generated, the first wake-up circuit 31 or the second wake-up circuit 32 and the standby circuit work to wake up the second power conversion chip 2, so as to recover power supply to the load circuit 4, and switch from the standby state to the load operation is realized. However, when the standby circuit is not a pure hardware circuit and has no memory as in the embodiment shown in fig. 1, the enable signal only lasts for the duration of the first wake-up signal and the second wake-up signal. However, since the load circuit 4 is powered back in a short time, so that the panel control circuit 41 is powered back, at this time, the panel control circuit 41 can implement real-time detection of the first wake-up signal and the second wake-up signal, so as to send out a continuous third wake-up signal, so as to continuously generate an enable signal to continuously wake up the second power conversion chip 2, thereby enabling to control and implement long-time power supply to the load circuit 4, and implement switching from the standby state to the load operation state.
The inverter 34 is used to invert the first wake-up signal, the second wake-up signal, and the third wake-up signal to form an enable signal. When one of the first wake-up signal, the second wake-up signal and the third wake-up signal is received, an enable signal can be formed to enable the second power conversion chip 2. The inverter has the advantages of high execution speed, low price, stable performance and low power consumption, can improve the execution speed of the standby circuit, can reduce the power consumption of the household appliance in the standby state, and can reduce the cost of the standby circuit. In other embodiments, the inverter 34 may be replaced by a microprocessor to receive the first wake-up signal, the second wake-up signal and the third wake-up signal and convert the short-duration pulse signal into the continuous enable signal, so as to implement the switching from the standby state to the load operation state with simple control logic, thereby making the system more stable.
In other embodiments, the standby circuit may include other wake-up circuits besides the first wake-up circuit 31, the second wake-up circuit 32 and the first wake-up circuit 33, so as to receive the wake-up signal, and enable the standby circuit to generate the enable signal to enable the second power conversion chip 2.
The load circuit 4 includes one or more of a display panel control circuit 41, a screen display circuit, a WIFI circuit, and a USB circuit. When the household appliance 100 is in the standby state, the load circuit 4 is not operated. The display panel control circuit 41 and the display panel 20 control chip are used to control the cooperation between the circuits when the household appliance 100 is in the load operation state, and the display panel 20 control chip can communicate with the main control panel 10 in the load operation state. The screen display circuit includes a TFT screen for displaying screen display data on the TFT screen. The WIFI circuit comprises a WIFI module and is used for realizing wireless communication with the outside through the WIFI module. The USB circuit is used for realizing the communication with the outside through a USB interface in a wired connection way. The load circuit is used for executing functions of screen display, WIFI connection, USB access and the like of the display panel. The second power conversion chip 2 may be configured to output a second power supply voltage V2 to supply power to the display panel control circuit 41 and the screen display circuit, and the second power conversion chip 2 is further configured to output a WIFI power supply voltage VDDWIFI to supply power to the WIFI module of the WIFI circuit, and output a USB power supply voltage VDDUSB to supply power to the USB power supply circuit.
The load circuit 4 may further include a third power conversion chip 45. The third power conversion chip 45 may be an LDO, and is used to convert a voltage of 5V into a voltage of 3.3V to power other devices of the load circuit.
It can be understood that when the household appliance 100 is in the load operation state, the first power conversion chip 1, the second power conversion chip 2, the standby circuit 3 and the load circuit 4 operate simultaneously. When the household appliance 100 is in the standby state, the first power conversion chip 1 and the standby circuit 3 keep working, the enable terminal 21 of the second power conversion chip 2 is at low level or high level so as to enable the second power conversion chip 2 not to work, thereby the power supply of the load circuit 4 is cut off, only the first power conversion chip 1 and the standby circuit 3 work in the standby state of the household appliance 100, other peripheral circuits do not work, and therefore the standby power consumption of the household appliance 100 can be greatly reduced.
When the household appliance 100 is in a load operation state, the display panel control chip and the main control panel 10 are in communication with each other to maintain the cooperation between the main control panel 10 and the display panel 20 during the operation of the household appliance 100. When the household appliance 100 is in a standby state, the display panel control chip and the main control panel 10 are disconnected from each other, and the display panel control chip cannot work, so that power consumption can be reduced, and the standby power consumption of the household appliance 100 can be greatly reduced.
In a specific example, when the household appliance 100 is in the load operation state, the LDO, the DCDC chip, the standby circuit 3, and the load circuit 4 operate simultaneously. When the household appliance 100 enters the standby state, the pin of the enabling terminal of the DCDC can be controlled to be at a low level, so that the DCDC chip does not work, the load circuit of the whole display panel is powered off, that is, most circuits are powered off, and the display panel 20 and the main control panel 10 do not communicate with each other, thereby greatly reducing the power consumption of the household appliance 100 in the standby state.
The household appliance 100 may further include a fourth power conversion chip, and the fourth power conversion chip may convert the 5V first supply voltage V1 output by the first power conversion chip 1 into a 3.3V fourth supply voltage V4, so as to supply power to a device requiring 3.3V in the standby circuit. Alternatively, the fourth power conversion chip may be connected to the main power supply, thereby connecting the main power supply voltage VM conversionAnd a fourth supply voltage V4 of 3.3V, thereby supplying the devices requiring 3.3V in the standby circuit.
In summary, in order to solve the technical problem that the standby power consumption of the household electrical appliance 100 is high, the present application designs a household electrical appliance 100 having a new standby power consumption control mode. The display panel 20 of the household appliance 100 is provided with a first power conversion chip 1 which always keeps supplying power and a second power conversion chip 2 whose working state can be controlled. The second power conversion chip 2 is a main power supply of the display panel 20, the standby circuit 3 is awakened by three wake-up signals to enable the operating state of the second power conversion chip 2, when standby is required, the second power conversion chip 2 does not operate, most circuits of the display panel 20 are not powered, and only the circuit powered by the first power conversion chip 1 is powered. In this way, in the standby state, the second power conversion chip 2 and the load circuit 4, etc., which do not need to supply power, are completely powered off. The first power conversion chip 1 only supplies power to the standby circuit 3, so that the standby power consumption is optimal, and the power conversion circuit has the advantages of high reliability, strong universality and the like.
The household appliance 100 may be a washing machine, a dryer refrigerator, an air conditioner, a television, and other household appliances, which are not limited in this embodiment.
