Water in the washing tub 5 enters the first circulating water path 14 under the action of the first circulating water path 15, is treated by the first water treatment unit, and produces water of a first property, which is then passed into the washing tub 5. The water in the washing tub 5 enters the second circulating water path 22 under the action of the second circulating pump 23, is treated by the second water treatment unit, and produces water of a second property, which is then passed into the washing tub 5, thereby achieving mixing of the first and second property waters in the washing tub 5. In a preferred embodiment, the water outlet of the first circulating water channel 14 and / or the water outlet of the second circulating water channel 22 is provided with a sprinkler head with a dispersed water spraying function to achieve sufficient mixing of the water of the first property and the water of the second property.

[0047] In another example, referring to Figure 2 The washing machine includes a circulating water circuit, the water inlet and outlet of which are both connected to the washing tub 5. A circulating pump is provided on the circulating water circuit, and a first water treatment unit is provided in the circulating water circuit. The circulating water circuit forms a first water flow path. The water in the washing tub 5 enters the circulating water circuit under the action of the circulating pump, and after being treated by the first water treatment unit, water of a first nature is generated and passed into the washing tub 5. The washing machine includes an outer tub 4, the washing tub 5 is rotatably provided in the outer tub 4, the second water treatment unit is provided at the bottom of the outer tub 4, and the passage between the outer tub 4 and the washing tub 5 forms a second water flow path. In this embodiment, the second water treatment unit is directly provided in the outer tub 4, thereby saving costs and improving operating efficiency. In a preferred embodiment, a sprinkler head with a dispersed water spraying function is provided at the outlet of the circulating water circuit to achieve sufficient mixing of the water of the first nature and the water of the second nature. In another preferred embodiment, the circulating water circuit includes a first buffer chamber, which is capable of buffering the water of the first nature. The first water treatment unit can be directly installed in the first buffer chamber, treating the water flowing into the first buffer chamber. Alternatively, the first water treatment unit can be located upstream of the first buffer chamber, allowing the water treated by the first water treatment unit to flow into the first buffer chamber for buffering. A second buffer chamber 2610 is provided at the bottom of the outer cylinder 4, with the second water treatment unit installed in the second buffer chamber 2610. The second buffer chamber 2610 is capable of buffering water of a second property and is directly installed in the second buffer chamber 2610.

[0048] In some embodiments, the water of the first property is positively charged water, and the water of the second property is negatively charged water. The washing machine also includes a positive charge concentration detection device and a negative charge concentration detection device. The positive charge concentration detection device is used to detect the positive charge concentration in the first buffer chamber, and the negative charge concentration detection device is used to detect the negative charge concentration in the second buffer chamber 2610. The control device is also configured to mix the positively charged water and the negatively charged water in the washing drum 5 when the positive charge concentration reaches a first target concentration and the negative charge concentration reaches a second target concentration, and use the energy generated by the instantaneous neutralization of the positive charge and the negative charge to kill bacteria and decompose stains at the same time.

[0049] In one achievable manner, referring to Figure 2 The washing machine includes a housing 1, a door 2, a door seal 3, an outer drum 4, a washing drum 5, a motor 6, a water inlet valve 7, a water inlet pipe 8, a detergent dispensing chamber 9, a water tank 10, a heating pipe 11, a drain valve 12, a drain pipe 13, and other main components. The washing machine also includes a circulating water circuit 24, which is equipped with a circulating pump 25 and a first ionization generator 16. The first ionization generator 16 processes the water in the circulating water circuit 24 to produce charged water. A first water outlet 17 is provided at the end of the circulating water circuit 24. The first water outlet 17 is preferably located at the top of the door seal 3 and is equipped with a spray head with a dispersed water spray function. A second ionization generator 19 is provided in a second buffer chamber 2610 at the bottom of the outer drum 4. When the water in the outer drum 4 enters the second buffer chamber 2610 and is processed by the second ionization generator 19, the charged water generated is directly stored in the inner and outer drums 4, namely, the washing water 20. The charged water sprayed from the first water outlet 17, i.e., the first outlet water 18, and the washing water 20 have opposite charges. The two water flows can be mixed in the washing tub 4, quickly neutralized, and release energy instantly to treat the laundry 21, effectively killing most of the bacteria and microorganisms in the laundry, while promoting the decomposition of stain components at the microscopic level, effectively improving the laundry cleaning rate, and will not cause damage or fading of the fabric.

[0050] Preferably, the first ionizer 16 generates positively charged water, while the second ionizer 19 generates negatively charged water. Clothes immersed in the negatively charged water possess a certain degree of sterilization properties, utilizing its strong redox properties to destroy the proteins and genetic material of various bacteria and viruses, thereby achieving a sterilization effect. Furthermore, the positively charged water, when circulated and sprayed on the clothes, can act similarly to a cationic softener, softening the clothes to a certain degree.

[0051] Preferably, a first cache chamber is provided on the circulating water circuit 14, and a first ionization generator 16 is arranged in the first cache chamber for storing prepared washing water with positive charge, and the start and stop of the circulating pump 15 are controlled by a control device and a corresponding algorithm to ensure that when spraying washing water, the negative charge concentration in the washing drum 4 and the positive charge concentration in the first cache chamber reach the set standards, thereby achieving better cleaning and sterilization effects.

[0052] According to an exemplary embodiment, this embodiment proposes a control method for a washing machine, which is used to control any of the washing machines proposed in the above embodiments. Figure 3 The control flow of a washing machine according to an exemplary embodiment is shown as follows Figure 1 , the control method comprises the following steps:

[0053] S31, obtaining a laundry processing mode of the washing machine;

[0054] S32. Determine the timing and / or order of introducing the water of the first property and the water of the second property into the washing tub according to the laundry treatment mode;

[0055] S33. The water of the first property and the water of the second property are introduced into the washing tub in a determined order.

[0056] The laundry treatment modes in this embodiment include one or more of a sterilization wash mode, a gentle wash mode, an oily stain wash mode, and a color protection wash mode. The laundry treatment mode can be determined based on user control instructions. Because different laundry treatment modes produce different laundry treatment effects on laundry, the order and / or timing of introducing the water of the first property and the water of the second property can be adjusted to achieve different laundry treatment effects under different laundry treatment modes.

[0057] In one example, the water of the first nature includes positively charged water, the water of the second nature includes negatively charged water, and the clothing treatment mode includes a first sterilization washing mode. The timing and / or order of introducing the water of the first nature and the water of the second nature into the washing tub is determined according to the clothing treatment mode, including: in the first sterilization washing mode, in the main wash phase, after introducing the negatively charged water into the washing tub for a first set time, the positively charged water is introduced into the clothing treatment tub. Figure 2In a washing machine with this function, during the main wash cycle, the second ionization generator is first turned on to generate negatively charged water, which is then used to soak clothes in the washing machine drum. This strong oxidation-reduction effect can reduce the proteins and genetic material of bacteria and viruses, thereby achieving a certain sterilization effect. After the first set time T1 is reached, the first ionization generator is turned on to generate positively charged water, which is sprayed into the drum through a circulating spray. At this time, the second ionization generator remains on, and the positively charged water and negatively charged water mix in the washing drum, quickly neutralizing and instantly releasing energy, further killing bacteria and microorganisms in the clothes, while also promoting the decomposition of stain components at the microscopic level.

[0058] In one example, the clothing treatment mode includes a second sterilization washing mode, and the timing and / or order of introducing water of the first property and water of the second property into the washing drum is determined according to the clothing treatment mode. It also includes: in the second sterilization washing mode, obtaining the positive charge concentration of positively charged water and obtaining the negative charge concentration of negatively charged water in the main wash stage, and when the positive charge concentration reaches the first target concentration and the negative charge concentration reaches the second target concentration, mixing the positively charged water and the negatively charged water in the washing drum.

[0059] Combine Figure 2 A washing machine is also available. Figure 3 According to the control flow chart, after the second sterilization wash mode is activated, the washing water level L2 in the washing tub is first detected. When it reaches the first set water level, the second ionization generator is activated to produce positively charged water in the washing tub. The circulation pump is then activated to fill the first buffer chamber with water. When the water level L1 in the first buffer chamber is detected to have reached the second set water level, the first ionization generator is activated to produce negatively charged water, and the circulation pump is simultaneously turned off to stop water inflow.

[0060] During the main wash stage, after detecting that the negative charge concentration N1 in the first buffer chamber and the positive charge concentration N2 of the washing water in the drum have reached their target concentrations, the circulation pump is turned on to spray the negatively charged water into the washing drum and mix it with the positively charged washing water. The energy generated by instantaneous neutralization is used to further kill bacteria and decompose stains.

[0061] Continue to detect the negative charge concentration N1 in the first buffer chamber and the charge concentration N2 of the washing water in the drum. When either value falls below its corresponding target concentration value, turn off the circulation pump and stop spraying. Repeat this cycle until the washing is completed or a command to stop preparing ionized water is received.

[0062] In one example, the laundry treatment mode includes a gentle washing mode, and the timing and / or order of introducing the water of the first property and the water of the second property into the washing tub is determined according to the laundry treatment mode. The method further includes: in the gentle washing mode, after the positively charged water is introduced into the washing tub for a second set time, the negatively charged water is introduced into the washing tub. Figure 2In a washing machine with this feature, during the main wash cycle, the first ionization generator is activated to generate positively charged water, similar to the cationic function of softener, which is sprayed into the washing tub to soften the clothes. After the second set time T2 is reached, the second ionization generator is activated to generate negatively charged water. During this time, the first ionization generator remains activated. The positive and negative charged water mix in the washing tub, quickly neutralizing and releasing energy instantly. This has a certain bactericidal effect and promotes the decomposition of stain components at the microscopic level. Simultaneously, during the rinse cycle, the first ionization generator can also be activated to generate positively charged water for spraying, further enhancing the softening effect.

[0063] In one example, the water of the first nature includes acidic water, the water of the second nature includes alkaline water, and the laundry treatment mode includes an oily stain washing mode. The timing and / or order of introducing the water of the first nature and the water of the second nature into the washing tub is determined according to the laundry treatment mode, including: in the oily stain washing mode, introducing alkaline water into the washing tub during the main wash phase, and introducing acidic water into the washing tub during the rinsing phase. Figure 2 During the main wash cycle, the alkaline electrolyzed water generator at the bottom of the outer drum activates to produce alkaline water, increasing the cleaning efficiency of oil stains. During the rinse cycle, the acidic electrolyzed water generator in the water circulation circuit activates to produce acidic water, which is sprayed into the inner drum to quickly neutralize alkaline residue in the clothes, achieving a rinsing effect and also sterilizing the clothes.

[0064] In one example, the clothing treatment mode includes a color protection washing mode, and the timing and / or order of introducing the water of the first property and the water of the second property into the washing drum is determined according to the clothing treatment mode. It also includes: in the color protection washing mode, acidic water is introduced into the washing drum during the main wash stage, and alkaline water is introduced into the washing drum during the rinsing stage. For chemical fiber clothing, since they are generally dyed in an acidic environment using acid dyes or reactive dyes, they are prone to fading when washed under alkaline conditions. Therefore, an acidic electrolytic water generator can be turned on in the main wash stage to produce weakly acidic water, which can effectively prevent chemical fiber clothing from fading and at the same time have a sterilizing effect on the clothing. In the rinsing stage, an alkaline electrolytic water generator is turned on to generate alkaline water to neutralize the acidic residues in the clothing, achieving a rinsing effect.
