[0021] The present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and not to limit the present application. In addition, it should be noted that only the parts related to the present application are shown in the drawings for the convenience of description, rather than all the structures.

In a specific embodiment, the device can be integrated in the washing machine. The following embodiments will be described by taking the device integrated in the washing machine as an example, and the device can be integrated in the washing machine by referring to Figure 1 The method can specifically include the following steps:

[0023] Step 101, detecting a real-time power supply voltage of the washing machine.

[0024] Specifically, a voltage detection device can be arranged on a power supply circuit of the washing machine, and the real-time power supply voltage of the washing machine is detected by using the voltage detection device.

[0025] Step 102, determining a voltage interval to which the real-time power supply voltage belongs, the voltage interval including an overvoltage interval and an undervoltage interval, if the real-time power supply voltage belongs to the overvoltage interval, executing step 103, if the real-time power supply voltage belongs to the undervoltage interval, executing step 104.

[0026] For example, an overvoltage threshold and an undervoltage threshold can be set in advance, the overvoltage interval is set according to the overvoltage threshold, and the undervoltage interval is set according to the undervoltage threshold, wherein the overvoltage threshold is greater than the undervoltage threshold.

[0027] Step 103, executing an overvoltage protection strategy according to a state of the washing machine.

[0028] Step 104, executing an undervoltage protection strategy according to the state of the washing machine.

[0029] For example, the state of the washing machine can include standby, running and the like, the standby state means that the washing machine is not working, the running state means that the washing machine is working, and the overvoltage protection strategy and the undervoltage protection strategy are different, that is, when the real-time power supply voltage belongs to the overvoltage interval, different overvoltage protection strategies are adopted according to different states of the washing machine, and when the real-time power supply voltage belongs to the undervoltage interval, different undervoltage protection strategies are adopted according to different states of the washing machine.

[0030] In the embodiment of the present application, the real-time power supply voltage of the washing machine can be detected, the voltage interval to which the real-time power supply voltage belongs can be determined, the voltage interval including an overvoltage interval and an undervoltage interval, if the real-time power supply voltage belongs to the overvoltage interval, an overvoltage protection strategy is executed according to the state of the washing machine, if the real-time power supply voltage belongs to the undervoltage interval, an undervoltage protection strategy is executed according to the state of the washing machine. That is, in the embodiment of the present application, the real-time power supply voltage of the washing machine and the state of the washing machine are detected, and in the case of undervoltage and overvoltage, different protection strategies are adopted to protect the washing machine according to the state of the washing machine, so that the washing machine can be more reasonably and appropriately protected, and the influence of voltage difference on the washing effect and the service life of the washing machine is reduced.

[0031] The control method of the washing machine provided by the embodiments of the present application is further described below, as shown in the figure, the method can include the following steps: Figure 2

[0032] Step 201, obtaining the voltage fluctuation value of the target region, the target region is the region where the current washing machine is located.

[0033] For example, the current washing machine can be any washing machine, which can have a networking function, when the washing machine reaches the user's home, the washing machine can connect to the server through the networking function, and obtain the voltage fluctuation value of the target region through the server. The specific method of obtaining the voltage fluctuation value can be as follows:

[0034] (1) Obtain the position information of the washing machine, and determine the target region according to the position information.

[0035] Specifically, the washing machine can have a positioning module, and the position information of the washing machine can be obtained by using the positioning module, and then the region where the washing machine is located is determined according to the position information, which is the target region. For example, the position information obtained by the washing machine positioning is Beijing Jiaotong University, and it can be determined that the target region is Haidian District, Beijing.

[0036] (2) Send a voltage query request to the server, and the identification information of the target region is included in the query request, so that the server queries the voltage fluctuation value of the target region based on the identification information.

[0037] That is, the washing machine can send a voltage query request carrying the identification information of the target region to the server, and the identification information can be the name, code, or code of the target region. After receiving the voltage query request, the server can query the voltage fluctuation value of the region identified by the identification information within a certain time period, which can be represented by the variance or standard deviation of the voltage. For example, the target region is Haidian District, Beijing, and the voltage query request can carry "Haidian District, Beijing". After receiving the query request, the server can query the power supply voltage data of Haidian District, Beijing in the last week, the last ten days, or the last month, and calculate the variance or standard deviation of the voltage according to the queried power supply voltage data. The calculated variance or standard deviation of the voltage is taken as the voltage fluctuation value of Haidian District, Beijing.

[0038] In the embodiments of the present application, the rated working voltage of the washing machine is the same as the theoretical power supply voltage of the target region, for example, both are 220V, but the theoretical power supply voltage of the target region can be different from the actual power supply voltage, for example, the actual power supply voltage of the target region can fluctuate around 220V. Therefore, the voltage fluctuation value of the target region needs to be obtained to guide the voltage protection process according to the voltage fluctuation value.

[0039] ​(3) receiving the voltage fluctuation value fed back by the server.

[0040] The above describes that the server directly feeds back the voltage fluctuation value of the target region to the washing machine. In actual application, the server can also feed back the power supply voltage data of the target region in a request period to the washing machine, and the washing machine calculates the voltage fluctuation value of the target region according to the power supply voltage data fed back by the server. The request period can be set according to actual needs, such as the last week, the last ten days, or the last month, which is not limited here.

[0041] Step 202, determine whether the voltage fluctuation value exceeds the preset fluctuation value, if yes, execute step 203, otherwise execute step 217 to end the processing.

[0042] The preset fluctuation value can be set according to actual needs or control requirements, such as 3V, 5V, etc. If the voltage fluctuation value exceeds the preset fluctuation value, it means that the voltage fluctuation of the region where the washing machine is located is large, which has a great influence on the washing effect of the washing machine and the service life of the washing machine, and the voltage difference protection needs to be performed on the washing machine. Therefore, the real-time power supply voltage of the washing machine can be detected. If the voltage fluctuation value does not exceed the preset fluctuation value, it means that the voltage fluctuation of the region where the washing machine is located is small, and no processing is required.

[0043] Step 203, detecting the real-time power supply voltage of the washing machine.

[0044] Step 204, determining whether the real-time power supply voltage belongs to the overvoltage interval or the undervoltage interval, if yes, executing step 205, if no, executing step 211.

[0045] In the embodiment of the application, the overvoltage threshold and the undervoltage threshold can be set in advance, the overvoltage interval is set according to the overvoltage threshold, and the undervoltage interval is set according to the undervoltage threshold. In addition, the target interval can also be set according to the overvoltage threshold and the undervoltage threshold.

[0046] In a specific embodiment, for example Figure 3 As shown in the figure, the overvoltage threshold is represented by U1, the undervoltage threshold is represented by U2, U3 is U2 plus a preset value, and U4 is U1 minus a preset value. The preset value can be set according to actual needs, such as 5V, 10V, etc. That is, U1>U4>U3>U2, the overvoltage interval can be [U1, ∞), the undervoltage interval can be (0, U2], and the target interval can be [U3, U4]. In addition, [U2, U1] can be understood as a normal interval.

[0047] Step 205, detecting and acquiring the state of the washing machine.

[0048] For example, the state of the washing machine can include standby, running, etc., the standby state means that the washing machine is not working, and the running state means that the washing machine is working.

[0049] Step 206, determine whether the state is standby or running, if it is standby, execute step 207, if it is running, execute step 208.

[0050] Step 207, prohibit the washing machine from starting, generate an overvoltage prompt information and display the overvoltage prompt information.

[0051] The overvoltage prompt information can be voice prompt information, text prompt information, etc. For example, the overvoltage prompt information can be an overvoltage prompt code PH (i.e. Power High), which can be displayed as PH on the display interface of the washing machine.

[0052] Step 208, record the first duration of the real-time power supply voltage belonging to the overvoltage interval, and when the first duration exceeds the first preset duration, cut off the power supply to all loads and send an alarm signal.

[0053] For example, all loads can be various loads in the washing machine that use the real-time power supply voltage to provide power, which can include motors, drainage, water inlet, forward and reverse rotation, etc. Since the voltage is too large at this time, the continuous operation of these loads can easily cause burning, so the power supply to these loads is cut off to protect these loads. In addition, the alarm signal can be a sound, light, etc.

[0054] Step 209, record the running breakpoint of the washing machine.

[0055] That is, record the washing program running breakpoint of the washing machine, which can be, for example, X minutes of washing, Y minutes of dehydration, Z minutes of drying, etc.

[0056] Step 210, continuously detect the real-time power supply voltage, and after the real-time power supply voltage changes from belonging to the overvoltage interval to belonging to the target interval, record the second duration of the real-time power supply voltage belonging to the target interval, and when the second duration exceeds the second preset duration, restore the power supply to all loads and continue running from the running breakpoint.

[0057] Step 211, detect and obtain the state of the washing machine.

[0058] Step 212, determine whether the state is standby or running, if it is standby, execute step 213, if it is running, execute step 214.

[0059] Step 213, prohibit the washing machine from starting, generate an overvoltage prompt information and display the overvoltage prompt information.

[0060] The under-voltage prompt information can be voice prompt information, text prompt information, etc.

[0061] At step 214, a third duration of the real-time power supply voltage belonging to the under-voltage interval is recorded, and a pulse signal feedback record of the motor of the washing machine is obtained, and when the third duration exceeds a third preset duration and the pulse signal feedback record meets a preset condition, the power supply to the motor is cut off and an alarm signal is sent.

[0062] The pulse signal feedback record is used to record the pulse signal feedback of the motor, and when the voltage is normal, the motor in the washing machine operates normally, and the motor feedbacks the pulse signal at a certain frequency, when in the under-voltage state, the motor operates slowly or stops operating, and the frequency of the feedback pulse signal may be reduced, or even no pulse signal is fed back.

[0063] The preset condition can include that no pulse signal feedback from the motor is received within a specified duration or the number of pulse signals feedback from the motor within a specified duration is less than a preset number value. For example, the preset condition is that no pulse signal feedback from the motor is received within 1 minute or the number of pulse signals feedback from the motor within 1 minute is less than 2.

[0064] In the under-voltage state, only the power supply to the motor is cut off, and the power supply to other loads is still normal, and other loads such as drainage, water inlet, forward and reverse rotation, etc. can allow part of the functions of the washing machine to be used, and reduce the influence of voltage difference on the washing program.

[0065] At step 215, the running breakpoint of the washing machine is recorded.

[0066] At step 216, the real-time power supply voltage is continuously detected, and after the real-time power supply voltage changes from belonging to the under-voltage interval to belonging to a target interval, a fourth duration of the real-time power supply voltage belonging to the target interval is recorded, and when the fourth duration exceeds a fourth preset duration, the power supply to the motor is restored, and the running is continued from the running breakpoint.

[0067] The first preset duration, the second preset duration, the third preset duration, and the fourth preset duration can be set according to actual needs, and the four can be the same or different. For example, the first preset duration and the second preset duration are the same, both are 100 milliseconds, and the third preset duration and the fourth preset duration are the same, both are 6 seconds.

[0068] At step 217, the process ends.

[0069] In addition, in the embodiment of the present application, the breakpoint operation is resumed by detecting that the real-time power supply voltage belongs to the target interval and recording the duration that the real-time power supply voltage belongs to the target interval, compared with the breakpoint operation resumed by detecting that the real-time power supply voltage belongs to the normal interval and recording the duration that the real-time power supply voltage belongs to the normal interval, the washing machine can be ensured to operate at a more suitable voltage, and the stability of the washing machine operation is improved.

[0070] In the embodiment of the present application, the washing machine can obtain a voltage fluctuation value of a target region, the target region being a region where the washing machine is currently located; it is determined whether the voltage fluctuation value exceeds a preset fluctuation value; if the voltage fluctuation value exceeds the preset fluctuation value, the real-time power supply voltage of the washing machine is detected; it is determined to which voltage interval the real-time power supply voltage belongs, the voltage interval including an overvoltage interval and an undervoltage interval; if the real-time power supply voltage belongs to the overvoltage interval, an overvoltage protection strategy is executed according to the state of the washing machine, and if the real-time power supply voltage belongs to the undervoltage interval, an undervoltage protection strategy is executed according to the state of the washing machine. That is, in the embodiment of the present application, when the voltage fluctuation of the local washing machine is large, the real-time power supply voltage of the washing machine and the state of the washing machine are detected, and in the case of undervoltage and overvoltage, different protection strategies are adopted to protect the washing machine in combination with the state of the washing machine, so that the washing machine can be more reasonably and appropriately protected, and the influence of voltage difference on the washing effect and the service life of the washing machine is reduced.
