Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a standby control method, device, equipment, control circuit, and washing machine. Background Technology

[0002] As washing machines are constantly being updated, users' requirements for standby power consumption are gradually increasing. In order to meet the needs of users in different situations and regions, various low-power control technologies are constantly emerging.

[0003] Currently, low-power technologies used in most mobile devices can achieve standby power consumption of 1W. However, these technologies suffer from problems such as complex control circuits and the inability to automatically power on. For example, non-zero standby power consumption, i.e., ultra-low power consumption, typically involves cutting off the power supply to the main load or putting the main chip into a sleep state to reduce the overall standby power consumption. However, after cutting off the overall power supply, users cannot power on the device by touching the power button or other methods; they need to manually power on the device, which is inconvenient and costly.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0055] The standby control method provided in this application can switch the power supply mode in the standby state of the washing machine to achieve zero power consumption standby relative to the power grid.

[0056] Example 1

[0057] Figure 1 The diagram illustrates the implementation flow of a standby control method provided by an embodiment of the present invention.

[0058] See Figure 1 The standby control method provided in this embodiment of the invention may include steps 101 to 102.

[0059] Step 101: Obtain the detection data of the washing machine, and determine the status of the washing machine based on the detection data.

[0060] In some embodiments, step 101 includes:

[0061] While the washing machine is running, the machine detects the motor stop time and determines the relationship between the stop time and the pre-stored critical time.

[0062] If the downtime is greater than or equal to the critical time, the liquid level of the washing machine is detected, and the relationship between the liquid level and the pre-stored critical liquid level is determined.

[0063] If the liquid level value is less than or equal to the critical liquid level value, then the drum temperature value of the washing machine is detected, and the relationship between the drum temperature value and the pre-stored critical temperature value is determined.

[0064] If the drum temperature value is less than or equal to the critical temperature value, the washing machine is determined to be in standby mode.

[0065] In some embodiments, step 101 further includes:

[0066] If the downtime is less than the critical time, the washing program continues.

[0067] If the liquid level value is greater than the critical liquid level value, a first fault alarm message is generated;

[0068] If the cylinder temperature value is greater than the critical temperature value, a second fault alarm message is generated.

[0069] In some embodiments, the washing machine enters a low-power or zero-power state while in standby mode. Before switching washing machine states, it is possible to fully identify whether the washing machine is in standby mode to achieve precise control. The process of determining whether the washing machine is in standby mode is as follows.

[0070] When the washing machine starts running and no shutdown signal is received, the system detects the motor's stop time and compares it with a pre-stored motor stop threshold time. The threshold time can be set according to the washing machine model and the current washing mode or program. During washing machine operation, the motor may temporarily stop according to the program settings, but these stops are short. By comparing the stop time with the threshold time, it can be determined whether the washing machine is in normal washing mode or standby mode.

[0071] If the motor stop time does not reach the critical time, the washing program will continue; if the motor stop time is greater than or equal to the critical time, the washing machine may have entered standby stop state, and then proceed to the subsequent standby judgment process.

[0072] Furthermore, the liquid level inside the washing drum is detected and compared with a pre-stored critical liquid level. If the liquid level is greater than the critical liquid level, it indicates that the washing machine has not drained the water after the motor stopped, which is an abnormal phenomenon. In this case, the washing machine is determined to have malfunctioned, the washing process is terminated, and the fault code is reported.

[0073] If the liquid level is less than or equal to the pre-stored critical liquid level, it indicates that the washing machine motor has stopped and the water has been drained. Based on this, the subsequent standby judgment process will begin.

[0074] Furthermore, the temperature of the washing machine drum is detected and compared with a pre-stored critical temperature value. If the temperature value is greater than the critical temperature value, it indicates that the washing machine's water and electricity heating and drying components are still heating after the washing machine motor has stopped and the water has been drained. In this case, the washing machine is determined to be faulty, and the fault code is reported.

[0075] If the temperature value is less than or equal to the critical temperature value, it means that the washing machine motor has stopped, the water has been drained, and the washing machine drum has stopped heating.

[0076] Based on the above three judgment conditions, the embodiments of the present invention can fully determine that the washing machine is in standby mode, and then execute the low power switching program.

[0077] Step 102: If the washing machine is in standby mode, control the washing machine to disconnect the mains power supply and use the backup power supply.

[0078] In some embodiments, step 102 includes:

[0079] Disconnect the power grid and shut down the motor system, drying system, and electric heating system of the washing machine;

[0080] The touch control system of the washing machine is powered by a backup power source.

[0081] In some embodiments, the switching process includes a direct low-power switching procedure, which sends a signal to disconnect the power grid and connects the photovoltaic function system, enabling the entire unit to achieve zero standby power consumption.

[0082] In some embodiments, the method provided by the present invention further includes:

[0083] In the standby state of the washing machine, in response to the power-on command, the washing machine is controlled to cut off the backup power supply and use the mains power supply.

[0084] Specifically, the method provided in this embodiment of the invention can use the parameters obtained by the in-cylinder sensor to determine the overall operating state S of the machine when the controller does not receive an active shutdown signal. Using the overall operating state S, the main chip U1 controls the integrated chip U2 through the C channel. The integrated chip U2 controls the switching between the mains power and the low-voltage power supply system through four channels I1, I2, O1, and O2.

[0085] The method provided in this invention can effectively control the standby power consumption and status of a washing machine. It can promptly control the switching of mains power for the overall function of the washing machine, rationally allocate the energy consumption of the entire machine, and save mains power. During the washing process, whether the washing machine has finished washing or has not started, it can accurately determine the timing of switching to grid power, significantly reducing the overall power consumption and achieving "zero power consumption" in standby mode.

[0086] Example 2

[0087] Figure 2 This diagram illustrates another implementation flow of the standby control method provided in an embodiment of the present invention.

[0088] See Figure 2 In a specific example, the standby control method provided by this embodiment of the invention is implemented as follows.

[0089] After the system starts running, the motor running time is detected to obtain the motor downtime T.

[0090] Specifically, if the machine does not receive an active shutdown signal, the machine detects and records the motor's downtime T starting from the moment the washing machine motor stops rotating. For example, if the initial time is Ta and the current time is Tb, then the current motor downtime is T = Tb - Ta.

[0091] If the motor running time T is less than the pre-stored critical time T1, then the predetermined program 1 is executed. In a specific example, the predetermined program 1 is to continue executing the current washing cycle.

[0092] If the motor stop time is greater than or equal to the pre-stored critical time T1, the liquid level L inside the washing machine is detected. If the motor stop time exceeds the critical time, further determination is made as to whether the washing machine should stop running.

[0093] Specifically, a liquid level detector is installed inside the washing machine. After the washing machine system starts executing the washing program, the liquid level detector begins to detect and record the liquid level L in the tub.

[0094] If the liquid level L is greater than the pre-stored critical liquid level L1, then pre-defined procedure 2 is executed. In a specific example, pre-defined procedure 2 terminates the current washing cycle, retrieves the fault location, and reports a fault code. This situation indicates that even after the washing machine has stopped running for more than the critical time, there is still water exceeding the critical liquid level inside the washing machine, indicating a malfunction that needs to be investigated.

[0095] If the liquid level of the washing machine is less than or equal to the pre-stored critical liquid level L1, then the drum temperature V of the washing machine is detected.

[0096] Specifically, a drum temperature detector is installed inside the washing machine to detect the temperature value V inside the drum.

[0097] If the drum temperature V is greater than the preset critical drum temperature V1, then pre-defined program 3 is executed. In a specific example, pre-defined program 3 detects the temperature of the water heating and drying components. If the temperature of the water heating or drying components is abnormal, the washing process is terminated and a fault code is reported. This situation indicates that after the motor stops and the water is drained, the drum temperature is too high, and the water heating or drying components of the washing machine have malfunctioned.

[0098] If the drum temperature V is less than or equal to the pre-stored critical drum temperature V1, then pre-defined program 4 is executed. In a specific example, pre-defined program 4 is to execute a low-power switching program. This type of situation occurs when the washing machine is in a shutdown state, with the motor stopped, water drained, and the heating device functioning normally, causing it to switch to a low-power state.

[0099] In a specific example, executing the low-power switching procedure includes sending a message to disconnect the power grid and activate the photovoltaic standby function system, so that the entire unit consumes zero power to the power grid during standby.

[0100] In summary, the method provided by the embodiments of the present invention can accurately determine the timing of the whole machine cutting off the power grid during the standby process, reduce the standby power consumption of the whole machine, and achieve a zero power consumption standby state relative to the power grid.

[0107] In some embodiments, the standby determination module 201 is specifically used for:

[0108] While the washing machine is running, the machine detects the motor stop time and determines the relationship between the stop time and the pre-stored critical time.

[0109] If the downtime is greater than or equal to the critical time, the liquid level of the washing machine is detected, and the relationship between the liquid level and the pre-stored critical liquid level is determined.

[0110] If the liquid level value is less than or equal to the critical liquid level value, then the drum temperature value of the washing machine is detected, and the relationship between the drum temperature value and the pre-stored critical temperature value is determined.

[0111] If the drum temperature value is less than or equal to the critical temperature value, the washing machine is determined to be in standby mode.

[0112] In some embodiments, the standby determination module 201 is specifically used for:

[0113] If the downtime is less than the critical time, the washing program continues.

[0114] If the liquid level value is greater than the critical liquid level value, a first fault alarm message is generated;

[0131] Example 5

[0132] On the other hand, a control circuit is provided, including a sensor module, a backup power supply, a backup power supply interface, a power grid interface, a power supply switching chip, and a main chip.

[0133] The sensor module is installed in the washing machine, and the output terminal of the sensor module is connected to the input terminal of the main chip. The control output terminal of the main chip is connected to the control input terminal of the power supply switching chip.

[0134] The power grid interface is connected between the power grid and the first power input terminal of the power supply switching chip;

[0135] The backup power interface is connected between the backup power supply and the second power input terminal of the power switching chip.

[0136] The first output terminal of the power supply switching chip is connected to the first power supply input terminal of the main chip, and the second output terminal of the power supply switching chip is connected to the second power supply input terminal of the main chip.

[0137] The power supply output terminal of the main chip is connected to the load.

[0138] In some embodiments, backup power sources include, but are not limited to, photovoltaic power supply devices, battery pack devices, etc.

[0139] Figure 5 A schematic diagram of the control circuit structure for the standby control method provided in an embodiment of the present invention is shown.

[0140] See Figure 5 In a specific example, the machine's operating state S is determined based on parameters collected by sensors inside the washing machine, until it is determined that the washing machine is in standby mode, and a predetermined program 4 is executed.

[0141] The main chip U1 sends control commands to the integrated chip U2 via the C communication circuit, and the integrated chip U2 performs actions through the control signal C. This includes switching between high and low voltage for the two inputs and two outputs.

[0142] I1 is the high-voltage output line of the power grid, and after passing through U2, the output voltage O1 supplies power to the entire downstream unit.

[0143] The machine is equipped with a photovoltaic power supply. The photovoltaic power supply outputs low voltage, which is input to U2 through the I2 line. Then, the same voltage O2 is output through U2 to power the back-end main chip U1 and the auxiliary low voltage system.

[0144] Specifically, when U2 is working, it has only one input I1 or I2 and only one output, namely the corresponding O1 or O2.

[0145] When the power switching command is issued to U1, a circuit conversion operation is performed, cutting off I1 and O1 while simultaneously turning on I2 and O2, thus achieving the conversion between high-voltage and low-voltage power. After U1 is powered by O2, it enters standby mode, with only the low-voltage system operating. The voltage of the low-voltage system can be adjusted according to the parameters of the control system components. When the entire unit is powered internally, the mains input is zero, and no current flows through the power lines, allowing the entire unit to achieve a zero-power standby state relative to the mains.

[0146] The present invention provides a method for determining the overall operating status of a washing machine based on parameters acquired by sensors inside the washing machine drum, even when the controller does not receive an active shutdown signal. Using this operating status, the main chip U1 controls the integrated chip U2 via channel C. The integrated chip U2 then controls the switching between mains power and low-voltage power supply via four channels I1, I2, O1, and O2, precisely and effectively controlling the power consumption and status of the machine during standby. The circuit provided in this invention can flexibly and effectively control the machine's ability to switch to power-off mode based on the washing function status, rationally allocating energy consumption and saving mains power. Furthermore, it can accurately determine the timing for switching to mains power during washing or before startup, automatically switching the energy mode to effectively reduce overall energy consumption and achieve zero standby power consumption.
