[0057] Embodiment 1

[0058] This embodiment describes the control method of the washing machine of the present application in detail.

[0060] Step 1: Obtain the running mode of the washing machine. The running mode of the washing machine can be manually input by the user.

[0061] Step 2: When the washing machine is in the barrel cleaning mode, obtain the cleaning parameters in the barrel body 101. The cleaning parameters in the barrel body 101 can be obtained by a sensor or a timer.

[0062] Step 3: When the cleaning parameters in the barrel body 101 exceed the preset cleaning parameter value, control the plasma generator 103 in the water box 102 to be turned on in the rinsing stage of the barrel body 101. The nitrate generated by the operation of the plasma generator 103 is dissolved in water to form disinfectant water containing nitrate ions, and the disinfectant water enters the barrel body 101 to kill bacteria and disinfect.

[0063] The control method of the washing machine of the embodiment comprises the following steps: obtaining the operation mode of the washing machine; when the washing machine is in the drum cleaning mode, obtaining the cleaning parameter in the drum 101; when the cleaning parameter in the drum 101 exceeds the preset value of the cleaning parameter, in the rinsing stage of the drum 101, the step of controlling the opening of the plasma generator 103 in the water box 102, the nitrate generated by the working of the plasma generator 103 is dissolved in water to form the disinfectant water containing nitrate ions, and the disinfectant water is made to enter the drum 101 for sterilization and disinfection; the water in the water box 102 covers the discharge needle discharge end of the plasma generator 103, when the plasma generator 103 works, air can be introduced into the discharge needle discharge end of the plasma generator 103, the nitrogen in the air is converted into nitrate by the high-energy electrons released by the plasma generator 103, the nitrate is dissolved in water, at this time, the disinfectant water containing nitrate ions is prepared in the water box 102, and the disinfectant water is discharged into the drum 101 to disinfect and sterilize the drum 101.

[0064] The control method of the washing machine of the embodiment can determine whether to open the plasma generator 103 to prepare disinfectant water based on the cleaning parameter in the drum 101, and the disinfectant water can kill bacteria in the drum 101, so the sterilization method of the embodiment has the advantages of high sterilization efficiency and flexible sterilization mode, and solves the technical problems of low sterilization efficiency and insufficient flexibility of sterilization mode in the prior art by using high-temperature washing for sterilization.

[0065] According to a preferred embodiment, when the cleaning parameter in the drum 101 does not exceed the preset value of the cleaning parameter, in the rinsing stage of the drum 101, the plasma generator 103 in the water box 102 is controlled to be closed, as shown in Figure 2 When the cleaning parameter in the drum 101 does not exceed the preset value of the cleaning parameter, it means that the degree of disinfection and sterilization required in the drum 101 has not been reached, at this time, in the rinsing stage of the drum 101, the plasma generator 103 in the water box 102 is controlled to be closed, and the conventional drum cleaning program is run to the end.

[0066] According to a preferred embodiment, when the plasma generator 103 is in the open state and the concentration of nitrate ions in the water box 102 is less than the minimum value of the preset concentration, the first water valve 104 and the second water valve 107 are controlled to be closed; when the plasma generator 103 is in the open state and the concentration of nitrate ions in the water box 102 is within the preset concentration range, the first water valve 104 is controlled to be opened, the drain valve 105 and the water pump 106 are controlled to be closed, and the disinfectant water in the water box 102 enters the drum 101, as shown in Figure 2Preferably, the preset concentration range is such that the nitrate ion concentration is such that the pH of the solution in the water box 102 is 0-7. The control method of the washing machine according to the preferred embodiment of the present application controls the first water valve 104 to open when the concentration of the nitrate ions in the water box 102 is within the preset concentration range, so that the sterilization water in the water box 102 can enter the tub 101 along with the rinsing water, thereby ensuring the sterilization and disinfection effect of the sterilization water on the tub.

[0067] According to a preferred embodiment, when the water inflow in the tub 101 reaches a preset water inflow, the first water valve 104 is controlled to close, the drain valve 105 and the water pump 106 are controlled to close, the impeller 109 in the communication water pipe 108 is controlled to open, and the washing water in the tub 101 is caused to return to the tub 101 again through the communication water pipe 108, as shown in FIG. 4. Figure 2 The control method of the washing machine according to the preferred embodiment of the present application causes the washing water in the tub 101 to return to the tub 101 again through the communication water pipe 108 by controlling the impeller 109 in the communication water pipe 108 to open, thereby accelerating the mixing of the washing water in the tub 101 and accelerating the sterilization and disinfection efficiency.

[0068] According to a preferred embodiment, the control method of the washing machine further comprises the steps of detecting the turbidity of the rinsing water in the tub 101 and controlling the opening and closing of the water pump 106 and the water inflow pipe 110 based on the turbidity of the rinsing water, as shown in FIG. 5. Figure 2 Specifically, the turbidity of the rinsing water is measured before the end of the rinsing. The control method of the washing machine according to the preferred embodiment of the present application controls the opening and closing of the water pump 106 and the water inflow pipe 110 based on the turbidity of the rinsing water, thereby not only ensuring the cleaning effect on the tub 101 but also saving water.

[0069] Preferably, when the turbidity of the rinsing water is less than or equal to a first preset turbidity, the impeller 109 in the communication water pipe 108 is controlled to close, the drain valve 105 is controlled to close, the water pump 106 and the second water valve 107 are controlled to open, and the rinsing water in the tub 101 is caused to enter the water box 102, as shown in FIG. 6. Figure 2 When the turbidity of the rinsing water is less than or equal to the first preset turbidity, it indicates that the rinsing water is still relatively clean, which can be pumped into the water box 102 by the water pump 106 and used again to prepare a nitrate water solution for sterilization and disinfection of the tub 101, thereby achieving the purpose of saving water.

[0070] Preferably, when the turbidity of the rinsing water is greater than the first preset turbidity, the impeller 109 in the communication water pipe 108 is controlled to close, the drain valve 105 is controlled to open, and the water inflow pipe 110 is controlled to open, as shown in FIG. 7. Figure 2The first preset turbidity degree can be set based on actual conditions, and is not limited herein. When the turbidity degree of the rinsing water is greater than the first preset turbidity degree, it indicates that the rinsing water is relatively turbid and is not suitable for reuse, and thus the rinsing water is drained through the drain valve 105, and then water is introduced again through the water inlet pipe 110 to prepare the nitrate water solution.

[0071] According to a preferred embodiment, the cleaning parameter in the tub 101 includes the turbidity degree of the main washing water in the tub 101 and / or the time interval from the last time the tub cleaning mode is started. Without limitation, the cleaning parameter in the tub 101 can also be other set parameters. The control method of the washing machine according to the preferred technical solution of the present embodiment includes the turbidity degree of the main washing water in the tub 101 and the time interval from the last time the tub cleaning mode is started, and the two parameters can be used to accurately determine whether the tub 101 needs to be disinfected and sterilized, so as to accurately control the on-off state of the plasma generator 103.

[0072] Preferably, when the turbidity degree of the main washing water in the tub 101 is greater than or equal to a second preset turbidity degree and / or the time interval from the last time the tub cleaning mode is started is greater than or equal to a preset number of days, the plasma generator 103 in the water box 102 is controlled to be turned on during the rinsing stage of the tub 101, as shown in FIG. 4. Figure 2 The second preset turbidity degree can be set based on actual conditions, and is not limited herein. The preset number of days is, for example, 20-50 days. When the turbidity degree of the main washing water in the tub 101 is greater than or equal to the second preset turbidity degree and / or the time interval from the last time the tub cleaning mode is started is greater than or equal to the preset number of days, it indicates that the tub 101 has not been cleaned for a long time and / or has a large amount of impurities, and thus the plasma generator 103 in the water box 102 is controlled to be turned on, so that the disinfectant water prepared by the operation of the plasma generator 103 can be used to disinfect and sterilize the tub 101, thereby ensuring the cleaning effect of the tub 101.

[0073] Preferably, when the turbidity degree of the main washing water in the tub 101 is less than the second preset turbidity degree and / or the time interval from the last time the tub cleaning mode is started is less than the preset number of days, the plasma generator 103 in the water box 102 is controlled to be turned off during the rinsing stage of the tub 101, as shown in FIG. 5. Figure 3 When the turbidity degree of the main washing water in the tub 101 is less than the second preset turbidity degree and / or the time interval from the last time the tub cleaning mode is started is less than the preset number of days, it indicates that the tub 101 does not need to be disinfected and sterilized, and thus the plasma generator 103 in the water box 102 is controlled to be turned off, and the conventional tub cleaning program is run to the end.

[0074] According to a preferred embodiment, when the washing machine is in washing mode, it acquires the washing parameters within the tub 101; when the washing parameters within the tub 101 exceed a preset value, the plasma generator 103 in the water tank 102 is turned off during the rinsing stage; when the washing parameters within the tub 101 do not exceed the preset value, the plasma generator 103 in the water tank 102 is turned on during the rinsing stage. The nitrate ions generated by the plasma generator 103 dissolve in the water to form disinfectant water containing nitrate ions, and this disinfectant water enters the tub 101. Figure 3 As shown. The preferred control method of the washing machine in this embodiment can determine whether to turn on the plasma generator 103 to prepare disinfectant water based on the washing parameters inside the tub 101, so as to kill bacteria on the clothes and thus ensure the cleaning effect of the clothes.

[0075] Preferably, the washing parameters within the tub 101 include the heating temperature and heating duration during washing within the tub 101. However, this is not a limitation; the washing parameters within the tub 101 can also be other preset parameters. In this preferred embodiment, the washing machine control method uses the heating temperature and heating duration within the tub 101 as the washing parameters. These two parameters allow for the determination of the washing effect on the clothes, thereby enabling accurate control of the on / off state of the plasma generator 103.

[0076] More preferably, when the heating temperature inside the tub 101 during washing is greater than or equal to the preset heating temperature, and the heating time is greater than or equal to the preset heating time, the plasma generator 103 in the water tank 102 is turned off during the rinsing stage of the clothes. Figure 3 As shown. The preset heating temperature is, for example, 40–95°C; the preset heating time is, for example, 3–60 minutes. When the heating temperature in the tub 101 during washing is greater than or equal to the preset heating temperature and the heating time is greater than or equal to the preset heating time, it indicates that the clothes have undergone pasteurization. At this time, the clothes have been well sterilized, and there is no need to prepare disinfectant water during the rinsing stage. At this time, the plasma generator 103 in the water tank 102 is turned off.

[0077] More preferably, when the heating temperature during washing in the tub 101 is less than the preset heating temperature and / or the heating time is less than the preset heating time, the plasma generator 103 in the water tank 102 is turned on during the rinsing stage of the clothes. Figure 4 As shown. When the heating temperature in the tub 101 during washing is less than the preset heating temperature and / or the heating time is less than the preset heating time, it indicates that the clothes have not undergone pasteurization. At this time, the clothes have not received adequate sterilization treatment. During the rinsing stage, disinfectant water needs to be prepared. At this time, the plasma generator 103 in the water tank 102 is turned on to prepare disinfectant water, which is used to kill bacteria on the clothes, thereby ensuring the cleaning effect of the clothes.
