[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] Currently, the common method for discharging household appliances is to connect a discharge resistor in parallel with the AC power supply, allowing discharge to occur through this resistor after the power is disconnected. However, this method cannot solve the problem of excessively large discharge capacitors and also increases hardware costs due to the parallel discharge resistor. Therefore, this application provides a device discharge method that can be applied to the main control unit module in household appliances.

[0061] To facilitate understanding of the device discharge method shown in the embodiments of this application, the structure of the target device involved in the embodiments of this application will be described exemplarily below:

[0062] See Figure 1 This is a schematic diagram of a module of the target device. For example... Figure 1 As shown, the target device includes a power input module, a main control unit module, a zero-crossing detection module, and a motor load. In practical applications, because the main control unit module and the zero-crossing signal detection module have energy storage components, they can still operate normally for a period of time when the target device loses power.

[0063] The following will describe in detail a device discharge method provided in the embodiments of this application, with reference to specific implementation methods. Figure 2 As shown, the specific steps are as follows:

[0064] S201, when a power failure is detected in the target device, the type of the target motor in the target device itself is determined.

[0065] The aforementioned target device is a household appliance with a plug, such as an air conditioner.

[0066] The aforementioned target motor refers to the motor inherent in the target equipment itself (i.e.) Figure 1 (The target motor load), for example, if the target device is an air conditioner, then the target motor can be the indoor motor in the air conditioner.

[0067] The motor types mentioned above refer to the type of the target motor, such as tapped motors, PG motors, and DC motors.

[0068] In this embodiment of the application, the motor type of the target motor is stored in a preset storage location. When the target device is detected to be powered off, the main control unit module can read the motor type of the target motor from the storage location.

[0069] Since the target device also has a zero-crossing detection module, in one embodiment, the power failure of the target device can be detected by the following steps: after the target device is powered on, the zero-crossing detection module detects the zero-crossing signal according to a preset cycle. If the zero-crossing detection module does not detect the zero-crossing signal for a preset number of consecutive cycles, it is determined that the target device is powered down. In this way, power failure detection can be achieved by the zero-crossing detection module built into the target device itself, without the need for external hardware devices, thus reducing hardware costs.

[0070] Users can set the detection cycle according to their actual situation. For example, for domestic 50Hz power supplies, a zero-crossing signal can generally be detected once every 20ms, so the detection cycle can be set to 20ms. For unidirectional detection, a zero-crossing signal can generally be detected once every 20ms, so the detection cycle can be set to 20ms.

[0071] As one possible implementation, the preset quantity can be 1. That is, if the zero-crossing detection module does not detect a zero-crossing signal in any cycle (i.e., the zero-crossing signal disappears for one cycle), it is considered that the target device has lost power. In this way, it is possible to quickly determine whether the target device has lost power.

[0072] As another possible implementation, the preset number can be 2. That is, the target device is considered to be powered down only when the zero-crossing detection module does not detect a zero-crossing signal for two consecutive cycles (i.e., the zero-crossing signal disappears for two consecutive cycles). In this way, false power-down detection caused by abnormal power supply or interference from high-power devices near the target device can be reduced, thereby improving the accuracy of power-down detection.

[0073] Understandably, the preset quantity can be other values, but considering that the detection time should not be too long, the preset quantity generally cannot be set too large.

[0074] S202, determine the control strategy for the target motor based on the motor type.

[0075] S203, based on the control strategy, control the target motor to operate so as to discharge the target device.

[0076] The following provides a unified explanation of S202 and S203:

[0077] In this embodiment, the motor type may include, but is not limited to, tapped motors, PG motors, and DC motors. A corresponding control strategy is pre-configured for each type of target motor. After determining the motor type of the target motor, the corresponding control strategy can be determined according to the configuration. Then, based on the control strategy, the target motor is controlled to operate, thereby discharging the target device.

[0078] Specifically, when the motor type is a tapped motor, the control strategy is to control the target motor to operate at the highest gear; when the motor type is a PG motor, the control strategy is to control the target motor to operate in a fully chopper-conducted manner; and when the motor type is a DC motor, the control strategy is to control the target motor to operate at the maximum duty cycle.

[0079] In this way, each type of motor can operate at its maximum power, thereby achieving the fastest possible discharge to the target device.

[0080] In practical applications, in order to exit the discharge mode in a timely manner, in another embodiment, the time required for discharge according to step S203 can be measured in advance, and a discharge duration can be set according to this time. The timing starts when S203 is executed. When the timing duration reaches the discharge duration, the discharge mode is exited, that is, the control of the target motor is stopped. In this way, the discharge mode can be exited in a timely manner after the discharge is completed, reducing the waste of computing resources.

[0081] In this application, upon detecting a power outage in the target device, the type of the target motor inherent in the target device is determined. Then, a control strategy for the target motor is determined based on the motor type. Finally, the target motor is controlled to operate based on the control strategy to discharge the target device. The solution provided in this application allows for discharge using the target motor inherent in the target device when it loses power. Compared to existing technologies that use external discharge resistors, this method can meet the requirement of a larger discharge capacitor, solving the problem of excessively large discharge capacitors. Furthermore, the solution provided in this application eliminates the need for external hardware devices during the discharge process, reducing the hardware costs required for the discharge process.

[0082] In another embodiment of this application, before determining the motor type of the target motor possessed by the target device itself, the following steps are further included:

[0083] S301, Detect whether the target motor is in standby mode.

[0084] S302, when the target motor is in standby mode, identify other running loads and stop supplying power to those other loads.

[0085] The following provides a unified explanation of S301 and S302:

[0086] In practical applications, the main control unit module can record the operating status of each load in real time. Each load has two possible states: one is running, and the other is standby (i.e., not running). When the target device loses power, it determines whether the target motor is in standby state based on the currently recorded operating status of each load, and determines other loads that are running.

[0087] Based on this, in this embodiment, when the target device loses power, if the target motor is running, steps S201-S203 can be executed directly to discharge the target device. If the target motor is in standby mode, in order to ensure that the main control unit module can successfully execute steps S201-S203, power supply to other running loads (such as the swing load on an air conditioner) can be stopped, thereby ensuring power supply to the main control unit module.

[0088] In another embodiment of this application, after controlling the target motor to operate based on the control strategy, the following steps are further included:

[0089] S401, Detect whether the target device has been re-powered.

[0090] S402, when the target device is detected to be powered on again, the operating parameters of the target device before the power failure are obtained.

[0091] S403, control the operation of the target device based on the operating parameters.

[0092] The following provides a unified explanation of S401-S403:

[0093] In this embodiment, after controlling the target motor to run based on the control strategy, a zero-crossing detection module can be used to continue detecting the zero-crossing signal. When the zero-crossing signal is detected again, it means that the target device is powered on again. At this time, the operating parameters of the target device before the power failure can be obtained, and the device can be controlled to run according to these operating parameters. In this way, after the target device is powered on again, it can quickly resume operation according to the operating parameters before the power failure without the need for manual adjustment by the user.

[0094] Based on the same technical concept, embodiments of this application also provide a device discharge apparatus, such as... Figure 5As shown, the device includes:

[0096] The second determining module 502 is used to determine the control strategy for the target motor based on the motor type;

[0097] The control module 503 is used to control the target motor to operate based on the control strategy in order to discharge the target device.

[0099] Detect whether the target motor is in standby mode;

[0100] If the target motor is in standby mode, identify other running loads and stop supplying power to those other loads.

[0101] In one possible implementation, the apparatus further includes a third determining module, the third determining module being configured to:

[0102] After the target device is powered on, the zero-crossing signal is detected by the zero-crossing detection module at a preset cycle. If the zero-crossing signal is not detected by the zero-crossing detection module for a preset number of consecutive cycles, it is determined that the target device is powered off.

[0103] In one possible implementation, the apparatus further includes an acquisition module, the acquisition module being configured to:

[0104] Detect whether the target device has been repowered;

[0105] Upon detecting that the target device has been powered back on, obtain the operating parameters of the target device before the power failure;

[0106] The target device is controlled to operate based on the aforementioned operating parameters.

[0107] In one possible implementation, the second determining module is specifically used for:

[0108] When the motor type is a tapped motor, the control strategy is to control the target motor to run at the highest gear.

Then, a control strategy for the target motor is determined based on the motor type. Finally, the target motor is controlled to operate based on the control strategy to discharge the target device.
