Description

洗衣控制方法和洗衣机 Laundry control method and washing machine

本发明要求 2013年 03月 18日向中国国家知识产? i提交的、申请号为 201310086052.0、名称为 "洗衣控制方法和洗衣机"的中国专利申请的优先权。 The present invention claims the priority of a Chinese patent application filed on March 18, 2013, to the Chinese National Intellectual Property, i, application number 201310086052.0, entitled "Laundry Control Method and Washing Machine".

技术领域 Technical field

本发明涉及洗衣控制技术领域，特别是涉及一种洗衣控制方法和洗衣机。 The present invention relates to the field of laundry control technology, and more particularly to a laundry control method and a laundry machine.

背景技术 Background technique

传统的洗衣机洗涤程序结束之后通常需要执行一次或多次漂洗程序。每个洗衣程序结束后无论衣物是否干净，都需重新更换使用大量清水以执行后续洗衣程序，导致水资源的大量浪费。 It is usually necessary to perform one or more rinsing procedures after the end of the conventional washing machine washing process. After each laundry program, no matter whether the clothes are clean or not, it is necessary to replace the use of a large amount of water to carry out the subsequent washing process, resulting in a large waste of water resources.

为了节省洗衣用水，现有技术提出通过洗衣机中的过滤组件对使用过的洗衣用水进行循环使用的节水洗衣方案。例如，洗衣机进行洗衣控制的过程中，如果完成某一洗衣程序后洗衣机内筒的洗衣用水经过滤组件进行过滤处理后又回流至内筒中，则可在下一洗衣程序中循环使用该洗衣用水而无需另进清水，明显节省洗衣用水量。 In order to save laundry water, the prior art proposes a water-saving laundry scheme for recycling used laundry water through a filter assembly in a washing machine. For example, during the washing control of the washing machine, if the washing water of the inner drum of the washing machine is filtered by the filtering component and then returned to the inner cylinder after completing a certain washing process, the washing water can be recycled in the next washing process without In addition to clear water, the amount of laundry water is obviously saved.

但实际生活中人们不仅存在节省洗衣用水量的需求，同时还对衣物洁净率、洗衣机维护成本等方面存在需求。上述方案仅考虑了节省洗衣用水量单方面因素而盲目节水，实现方式单一，不能对洗衣机节水洗衣流程实现灵活的智能控制，且过滤组件的使用寿命通常较短。 However, in real life, people not only have the need to save the amount of water used for washing, but also have a need for clothing cleanliness and washing machine maintenance costs. The above solution only considers the single factor of saving the water consumption of the laundry and blindly saves water, and the implementation mode is single, and the flexible intelligent control of the washing machine water-saving laundry process cannot be realized, and the service life of the filter component is usually short.

For the sake of clarity and conciseness, not all features of an actual implementation are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such practical embodiment in order to achieve the developer's specific objectives, for example, compliance with system and business related constraints, and these Restrictions may vary from implementation to implementation.

The representations and descriptions of components and processes known to those of ordinary skill in the art that are not relevant to the present invention are omitted.

图 1为本发明实施例一提供的洗衣控制方法的流程图。如图 1所示，本实施例提供的洗衣控制方法包括：步骤 11: 检测洗衣用水的温度和浊度。 FIG. 1 is a flowchart of a laundry control method according to Embodiment 1 of the present invention. As shown in FIG. 1, the laundry control method provided in this embodiment includes: Step 11: Detect the temperature and turbidity of the wash water.

步骤 12: 根据温度检测值和浊度检测值，自动选择在当前洗衣程序中是否经洗衣机的过滤组件循环使用该洗衣用水。 Step 12: Based on the temperature detection value and the turbidity detection value, it is automatically selected whether or not the laundry water is recycled through the filter unit of the washing machine in the current laundry program.

本发明各实施例中，当前洗衣程序可为洗衣流程的某一洗衣程序，例如：当前洗^ ^呈序为洗序。例如：当温度检测值和浊度检测值均满足一定条件时，可自动选择在洗涤程序中循环使用洗衣用水，即在洗涤程序中边洗衣边循环洗衣用水。 In various embodiments of the present invention, the current laundry program may be a certain laundry program of the laundry process, for example: the current washing sequence is washing. For example: When both the temperature detection value and the turbidity detection value satisfy certain conditions, the laundry water can be automatically selected to be recycled in the washing program, that is, the laundry water is circulated while washing in the washing program.

在实际应用中：一方面，过滤组件的滤膜通常存在一定的耐温阈值，将超过该耐温阈值的水引入过滤组件，则会损坏该过滤组件；另一方面，过滤组件的过滤处理性能也有一定的限度，如果将浊度超过一定浊度阈值的洗衣用水引入过滤组件，则会增加过滤组件过滤处理的负荷，降低洗衣用水过滤处理效果而影响衣物洗净率，同时还会缩短过滤组件的使用寿命。 In practical applications: On the one hand, the filter membrane of the filter component usually has a certain temperature threshold, and the introduction of water exceeding the temperature threshold into the filter component may damage the filter component; on the other hand, the filtration performance of the filter component There is also a limit. If the laundry water with turbidity exceeding a certain turbidity threshold is introduced into the filter assembly, the load of the filter component filtration treatment is increased, the laundry water filtration treatment effect is reduced, and the laundry washing rate is affected, and the filter assembly is also shortened. The service life.

本实施例通过检测洗衣用水的温度和浊度，并将温度检测值和浊度检测值共同作为是否循环使用洗衣用水的选择因素，由此在不损坏过滤组件、降低增加过滤组件过滤处理的负荷、满足衣物洗净率要求的基础上，尽可能的节省洗衣用水，实现了对洗衣机节水洗衣流程的智能控制，延长了过滤组件的使用寿命，降低洗衣机的维护成本。 In this embodiment, the temperature and turbidity of the washing water are detected, and the temperature detecting value and the turbidity detecting value are collectively used as a selection factor for circulating the washing water, thereby reducing the load of the filtering component and reducing the filtering process of the filtering component. On the basis of meeting the washing rate requirements of the clothes, the laundry water is saved as much as possible, and the intelligent control of the water-saving laundry process of the washing machine is realized, the service life of the filter assembly is prolonged, and the maintenance cost of the washing machine is reduced.

图 2为本发明实施例二提供的洗衣控制方法的流程图。如图 2所示，本实施例提供的洗衣控制方法包括： 2 is a flow chart of a laundry control method according to Embodiment 2 of the present invention. As shown in FIG. 2, the laundry control method provided in this embodiment includes:

步骤 21: 检测洗衣用水的温度，并将所述温度检测值与预定温度阈值进行比较。 Step 21: Detect the temperature of the laundry water and compare the temperature detection value with a predetermined temperature threshold.

如果在洗衣流程中启用了加热洗衣用水功能或使用温度较高的洗衣用水，则可通过温度传感器对洗衣用水的温度进行检测。 If the heated laundry water function is enabled or the higher temperature laundry water is used in the laundry process, the temperature of the laundry water can be detected by the temperature sensor.

在获取温度检测值之后，可将温度检测值与温度阈值进行比较。温度阈值可根据实际需要预先设置，如根据对洗衣用水进行过滤处理的过滤组件的耐温阈值预先设置，温度阈值小于或等于过滤组件的耐温阈值。根据温度检测值和温度阈值的比较结果，判断将该洗衣用水引入过滤组件进行过滤处理是否会对过滤组件造成损坏。 After the temperature detection value is obtained, the temperature detection value can be compared with the temperature threshold. The temperature threshold may be preset according to actual needs. For example, the temperature threshold of the filter component for filtering the laundry water is preset, and the temperature threshold is less than or equal to the temperature threshold of the filter assembly. Based on the comparison between the temperature detection value and the temperature threshold, it is judged whether the introduction of the laundry water into the filter unit for filtering treatment may cause damage to the filter assembly.

步骤 22: 如果所述温度检测值小于或等于所述温度阈值，则检测该洗衣用水的浊度，并将浊度检测值与预定的浊度阈值进行比较。如果温度检测值小于或等于温度阈值，则说明该洗衣用水的温度没有超过过滤组件滤膜的耐温值，洗衣用水的温度满足要求；在此基础上，进一步判断洗衣用水的浊度是否满足一定的要求。 Step 22: If the temperature detection value is less than or equal to the temperature threshold, detect the turbidity of the laundry water, and compare the turbidity detection value with a predetermined turbidity threshold. If the temperature detection value is less than or equal to the temperature threshold, it indicates that the temperature of the washing water does not exceed the temperature resistance value of the filter component filter, and the temperature of the washing water meets the requirement; on this basis, further determining whether the turbidity of the washing water satisfies a certain value Requirements.

步骤 23: 如果浊度检测值小于或等于所述浊度阈值，则在当前洗衣程序中经所述过滤组件循环使用该洗衣用水，否则在当前洗衣程序中不经所述过滤组件循环使用该洗衣用水。 Step 23: If the turbidity detection value is less than or equal to the turbidity threshold, the laundry water is recycled through the filter assembly in the current laundry program, otherwise the laundry is recycled in the current laundry program without the filter assembly. Use water.

可通过浊度传感器对洗衣用水的浊度进行检测，浊度阈值可根据实际需要预先设置。可选的，可在当前洗衣程序（如洗涤程序或漂洗程序）执行一定时长后，检测当前洗衣用水的浊度。如果浊度检测值小于浊度阈值，说明当前洗衣用水较脏，该情形下可优先考虑衣物洗净率、过滤组件过滤处理负荷等因素，洗衣机自动选择不经过滤组件循环使用该洗衣用水。如果浊度检测值大于或等于浊度阈值，说明当前洗衣用水较为干净，该情形下可优先考虑洗衣节水量，洗衣机自动选择经过滤组件循环使用该洗衣用水，即经洗衣筒排出的洗衣用水经过滤组件过滤处理后再次回流到洗衣筒内循环使用。 The turbidity of the washing water can be detected by the turbidity sensor, and the turbidity threshold can be set in advance according to actual needs. Optionally, the turbidity of the current laundry water can be detected after a current laundry program (such as a washing program or a rinsing program) is performed for a certain period of time. If the turbidity detection value is less than the turbidity threshold, it indicates that the current laundry water is dirty. In this case, factors such as laundry washing rate, filtration component filtration processing load, etc. may be prioritized, and the washing machine automatically selects the laundry water to be recycled without using the filtering component. If the turbidity detection value is greater than or equal to the turbidity threshold, the current laundry water is relatively clean. In this case, the laundry water saving amount can be prioritized, and the washing machine automatically selects the circulating water to be used by the filtering component, that is, the washing water discharged through the washing tub. The filter assembly is filtered and then recirculated to the drum for recycling.

步骤 24: 如果所述温度检测值大于预定的温度阈值，则在当前洗衣程序中不经所述过滤组件循环使用该洗衣用水。 Step 24: If the temperature detection value is greater than a predetermined temperature threshold, the laundry water is not recycled in the current laundry program without the filter assembly.

如果洗衣用水的温度检测值大于温度阈值，则自动选择在当前洗衣程序不经过滤组件循环使用该洗衣用水。该情形可将该洗衣用水排出洗衣机外而另进清水以继续洗衣，以避免温度过高的洗衣用水经过滤组件过滤处理的过程中对过滤组件造成损坏。 If the temperature detection value of the laundry water is greater than the temperature threshold, the laundry water is automatically selected to be recycled in the current laundry program without the filter assembly. In this case, the laundry water can be drained out of the washing machine and the water can be further washed to continue the washing to avoid damage to the filter assembly during the filtration process of the excessively high temperature of the washing water.

可见，本实施例首先确保洗衣用水温度不会损坏过滤组件，再权衡衣物洗净率、过滤组件过滤处理负荷和洗衣用水量，以在降低增加过滤组件过滤处理的负荷、满足衣物洗净率要求的基础上尽可能的节省洗衣用水，实现了对洗衣机节水洗衣流程的智能控制，延长了过滤组件的使用寿命，降低洗衣机的维护成本。 It can be seen that this embodiment firstly ensures that the temperature of the washing water does not damage the filter assembly, and then weighs the washing rate of the laundry, the filtering treatment load of the filtering component, and the amount of washing water, so as to reduce the load of the filtering process of the filtering component and meet the washing rate requirement of the laundry. On the basis of saving laundry water as much as possible, the intelligent control of the water-saving laundry process of the washing machine is realized, the service life of the filter assembly is prolonged, and the maintenance cost of the washing machine is reduced.

当然，在其他实施例中也可以采用先判断浊度再结合温度判断是否经过滤组件循环使用洗衣用水的方式。例如：检测洗衣用水的浊度，并将所述浊度检测值与预定浊度阈值进行比较。如果所述浊度检测值小于或等于所述浊度阈值，则检测该洗衣用水的温度，并将温度检测值与预定的温度阈值进行比较。如果温度检测值小于或等于所述温度阈值，则在当前洗衣程序中经所述过滤组件循环使用该洗衣用水，否则在当前洗衣程序中不经所述过滤组件循环使用该洗衣用水。如果所述浊度检测值大于预定的浊度阈值，则在当前洗衣程序中不经所述过滤组件循环使用该洗衣用水。该方案首先考虑衣物洗净率、过滤组件过滤处理负荷，再确保洗衣用水温度不会损坏过滤组件，二者均满足一定条件时尽可能的节省洗衣用水，实现了对洗衣机节水洗衣流程的智能控制，延长了过滤组件的使用寿命，降低洗衣机的维护成本。 Of course, in other embodiments, it is also possible to determine whether the turbidity is combined with the temperature to determine whether the washing water is recycled through the filter assembly. For example: The turbidity of the laundry water is measured and the turbidity detection value is compared to a predetermined turbidity threshold. If the turbidity detection value is less than or equal to the turbidity threshold, the temperature of the laundry water is detected, and the temperature detection value is compared with a predetermined temperature threshold. If the temperature detection value is less than or equal to the temperature threshold, the laundry water is recycled through the filter assembly in the current laundry program, otherwise it is not in the current laundry program. The filter assembly recycles the wash water. If the turbidity detection value is greater than a predetermined turbidity threshold, the laundry water is not recycled for use in the current laundry program without the filtration assembly. The scheme first considers the laundry washing rate, the filtration component to filter the processing load, and then ensures that the washing water temperature does not damage the filter assembly. When both meet certain conditions, the laundry water is saved as much as possible, and the intelligent water-saving laundry process of the washing machine is realized. Control, extending the life of the filter assembly and reducing the maintenance cost of the washing machine.

在上述技术方案的基础上，洗衣控制方法还可包括：在循环使用洗衣用水的洗衣程序结束之后，自动执行清洗过滤组件的步骤。本方案在经过滤组件对洗衣用水进行过滤处理后实现过滤组件的自动清洗，以及时清理过滤组件的滤膜上拦截的污物，避免了因污物的长期残留造成过滤组件清洗困难，有利于延长过滤组件的使用寿命，降低洗衣机的维护成本。 Based on the above technical solution, the laundry control method may further include: automatically performing the step of cleaning the filter assembly after the end of the washing process for recycling the laundry water. The solution realizes the automatic cleaning of the filter component after filtering the laundry water through the filter component, and timely cleans the dirt intercepted on the filter membrane of the filter component, thereby avoiding difficulty in cleaning the filter component due to long-term residue of the dirt, which is beneficial to the cleaning. Extend the life of the filter assembly and reduce the maintenance cost of the washing machine.

可选的，清洗过滤组件的步骤包括：气洗步骤和水洗步骤。气洗步骤：使气体经过过滤组件，以吹散所述过滤组件的滤膜上拦截的污物。水洗步骤：用水冲洗滤膜，并将冲洗后的出洗衣机外。 Optionally, the step of cleaning the filter assembly comprises: a gas washing step and a water washing step. Air wash step: The gas is passed through a filter assembly to blow off the dirt trapped on the filter membrane of the filter assembly. Washing step: Rinse the filter with water and rinse it out of the washing machine.

所述气洗步骤和水洗步骤的执行时序可根据实际需要设置，因此对过滤组件清洗的实现方式非常灵活，可更好满足实际应用的多样化需求。 The execution timing of the air washing step and the water washing step can be set according to actual needs, so the implementation of cleaning the filter assembly is very flexible, and can better meet the diversified needs of practical applications.

例如：在清洗所述过滤组件的过程中：所述气洗步骤和所述水洗步骤分时执行，如可先执行所述气洗步骤再执行所述水洗步骤。该方案对过滤组件先后进行气洗和水洗，即首先通过气体的抖散作用将滤膜表面的污物剥离滤膜表面，然后再用水进行冲洗，故与单独的用水洗相比，该方案能够节省冲洗水，而且克服了单独水洗时，污物在超滤膜上不易冲洗掉的缺点，能将超滤膜清洗的更干净、彻底。 For example: During the cleaning of the filter assembly: the air washing step and the water washing step are performed in a time-sharing manner, such as performing the air washing step and then performing the water washing step. The solution sequentially washes and washes the filter components, that is, firstly, the dirt on the surface of the filter membrane is peeled off from the surface of the filter membrane by the dissipating action of the gas, and then washed with water, so that the solution can be compared with the separate water washing. It saves the flushing water and overcomes the disadvantage that the dirt is not easily washed out on the ultrafiltration membrane when it is washed separately, and the ultrafiltration membrane can be cleaned more thoroughly.

又例如：在清洗所述过滤组件的过程中：所述气洗步骤和所述水洗步骤同时执行，如：在控制气体经过过滤组件以吹散所述过滤组件的滤膜上拦截的污物的同时，用水冲洗滤膜，并将冲洗后的水排出洗衣机外。该方案对过滤组件同时进行气洗和水洗，与单独的用水^目比，能够节省冲洗水，而且克服了单独水洗时，污物在超滤膜上不易冲洗掉的缺点，能将超滤膜清洗的更干净、彻底。 For another example: during the cleaning of the filter assembly: the air washing step and the water washing step are performed simultaneously, such as: controlling the gas intercepted on the filter membrane of the filter assembly to pass the filter assembly to blow off the filter assembly At the same time, rinse the filter with water and drain the rinsed water out of the washing machine. The solution simultaneously purifies and washes the filter assembly, and saves the flushing water compared with the water alone, and overcomes the disadvantage that the dirt is not easily washed off on the ultrafiltration membrane when the water is washed separately, and the ultrafiltration membrane can be removed. Cleaner and cleaner.

图 3为本发明实施例三提供的洗衣机的原理框图。如图 3所示，本实施例提供的洗衣机包括：自动控制模块 31。 3 is a schematic block diagram of a washing machine according to a third embodiment of the present invention. As shown in FIG. 3, the washing machine provided in this embodiment includes: an automatic control module 31.

自动控制模块 31用于检测洗衣用水的温度和浊度，并根据温度检测值和浊度检测值，自动选择当前洗衣程序中是否经洗衣机的过滤组件循环使用该洗衣用水。本实施例通过检测洗衣用水的温度和浊度，并将温度检测值和浊度检测值共同作为是否循环使用洗衣用水的选择因素，由此在不损坏过滤组件、降低增加过滤组件过滤处理的负荷、满足衣物洗净率要求的基础上，尽可能的节省洗衣用水，实现了对洗衣机节水洗衣流程的智能控制，延长了过滤组件的使用寿命，降低洗衣机的维护成本。 The automatic control module 31 is configured to detect the temperature and turbidity of the washing water, and automatically select whether the filter component of the washing machine is circulated in the current washing program according to the temperature detecting value and the turbidity detecting value. Use this laundry water. In the present embodiment, the temperature and turbidity of the washing water are detected, and the temperature detecting value and the turbidity detecting value are collectively used as a selection factor for recycling the washing water, thereby reducing the load of the filtering component and reducing the filtering process of the filtering component. On the basis of meeting the washing rate requirements of the clothes, the laundry water is saved as much as possible, and the intelligent control of the water-saving laundry process of the washing machine is realized, the service life of the filter assembly is prolonged, and the maintenance cost of the washing machine is reduced.

当前洗衣程序可为洗衣流程的某一洗衣程序，例如：当前洗衣程序为洗涤程序。可选的，自动控制模块 31可包括：温度检测单元 311、自动控制单元 312和浊度检测单元 313。 The current laundry program can be a laundry program for the laundry process, for example: The current laundry program is a washing program. Optionally, the automatic control module 31 may include: a temperature detecting unit 311, an automatic control unit 312, and a turbidity detecting unit 313.

在一种可选的实施方式中可以先判断温度再结合浊度判断是否经过滤组件循环使用洗衣用水。该情形下，温度检测单元 311用于检测洗衣用水的温度。浊度检测单元 313用于检测该洗衣用水的浊度。自动控制单元 312用于将所述温度检测值与预定温度阈值进行比较，如果所述温度检测值小于或等于所述温度阈值，则将浊度检测值与预定的浊度阈值进行比较，如果浊度检测值小于或等于所述浊度阈值，则在当前洗衣程序中经所述过滤组件循环使用该洗衣用水，否则在当前洗衣程序中不经所述过滤组件循环使用该洗衣用水。自动控制单元 312还用于如果所述温度检测值大于预定的温度阈值，则在当前洗衣程序中不经所述过滤组件循环使用该洗衣用水。 In an alternative embodiment, the temperature can be determined by combining the turbidity to determine whether the wash water is recycled through the filter assembly. In this case, the temperature detecting unit 311 is for detecting the temperature of the laundry water. The turbidity detecting unit 313 is for detecting the turbidity of the laundry water. The automatic control unit 312 is configured to compare the temperature detection value with a predetermined temperature threshold, and if the temperature detection value is less than or equal to the temperature threshold, compare the turbidity detection value with a predetermined turbidity threshold, if turbid If the degree of detection is less than or equal to the turbidity threshold, the laundry water is recycled through the filter assembly in a current laundry program, otherwise the laundry water is not recycled in the current laundry program without the filter assembly. The automatic control unit 312 is further configured to recycle the laundry water without the filter assembly in the current laundry program if the temperature detection value is greater than a predetermined temperature threshold.

该方案首先确保洗衣用水温度不会损坏过滤组件，再权衡衣物洗净率、过滤组件过滤处理负荷和洗衣用水量，以在降低增加过滤组件过滤处理的负荷、满足衣物洗净率要求的基础上尽可能的节省洗衣用水，实现了对洗衣机节水洗衣流程的智能控制，延长了过滤组件的使用寿命，降低洗衣机的维护成本。 The solution first ensures that the temperature of the washing water does not damage the filter assembly, and then weighs the washing rate of the laundry, the filtration treatment load of the filter unit, and the amount of laundry water, in order to reduce the load on the filtration treatment of the filter unit and meet the requirements of the laundry washing rate. The laundry water is saved as much as possible, and the intelligent control of the water-saving laundry process of the washing machine is realized, the service life of the filter assembly is prolonged, and the maintenance cost of the washing machine is reduced.

In this case, the turbidity detecting unit 313 is for detecting the turbidity of the laundry water. The temperature detecting unit 311 is for detecting the temperature of the laundry water. The automatic control unit 312 is configured to compare the turbidity detection value with a predetermined turbidity threshold, and if the turbidity detection value is less than or equal to the turbidity threshold, compare the temperature detection value with a predetermined temperature threshold, If the temperature detection value is less than or equal to the temperature threshold, the laundry water is recycled through the filter assembly in a current laundry program, otherwise the laundry water is not recycled in the current laundry program without the filter assembly. The automatic control unit 312 is further configured to recycle the laundry water without using the filter assembly in a current laundry program if the turbidity detection value is greater than a predetermined turbidity threshold. The solution first considers the washing rate of the clothes, the filtration treatment load of the filter components, and ensures that the temperature of the washing water does not damage the filter components.

The filter assembly cleaning module is used to automatically clean the filter assembly after the end of the laundry program that recycles the wash water. The solution realizes automatic cleaning of the filter assembly after filtering the laundry water through the filter assembly, and timely cleans the dirt intercepted on the filter membrane of the filter assembly, thereby avoiding difficulty in cleaning the filter assembly due to long-term residue of the dirt, which is beneficial to the cleaning. Extend the life of the filter assembly and reduce the maintenance cost of the washing machine.

可选的，所述过滤组件清洗模块包括：气洗控制单元和水洗控制单元。气洗控制单元，用于控制气体经过过滤组件，以吹散所述过滤组件的滤膜上拦截的污物。水洗控制单元，用于控制水流冲洗滤膜，并将冲洗后的水排出洗衣机外。 Optionally, the filter component cleaning module comprises: an air washing control unit and a water washing control unit.

The solution sequentially washes and washes the filter components, that is, firstly, the dirt on the surface of the filter membrane is peeled off from the surface of the filter membrane by the vibration of the gas, and then washed with water, so that the solution can be compared with the water alone.

Reduce the maintenance cost of the washing machine. For the working mechanism of the washing machine, refer to the corresponding description of the above method embodiment, and details are not described herein again.

下面不妨结合如图 4所示的洗衣机为例，举例说明本发明实施例洗衣控制方法的一个可选的洗衣流程： In the following, an optional washing process of the laundry control method of the embodiment of the present invention is exemplified by taking the washing machine shown in FIG. 4 as an example:

进水步骤：清水经过进水阀 1进入到洗涤剂投放盒 2，将洗涤剂冲入到洗涤内筒 3内，参与洗涤。 Inlet step: The clean water passes through the inlet valve 1 and enters the detergent delivery box 2, and the detergent is flushed into the washing inner cylinder 3 to participate in the washing.

洗涤步骤：洗涤内筒内的衣物。洗涤结束之后，通过温度传感器 20 检测洗衣用水的温度，如果温度检测值小于或等于过滤组件滤膜的耐温阈值（即温度阈值），则通过浊度传感器 5检测洗衣用水的浊度。根据浊度检测值和预定的浊度阈值的比较结果，执行下述（方案 1 )或（方案 2 )。 Washing step: Wash the laundry in the inner cylinder. After the washing is finished, the temperature of the washing water is detected by the temperature sensor 20, if the temperature detecting value is less than or equal to the temperature threshold of the filter component filter. The value (i.e., the temperature threshold) is used to detect the turbidity of the laundry water by the turbidity sensor 5. Based on the comparison result of the turbidity detection value and the predetermined turbidity threshold, the following (Scheme 1) or (Scheme 2) is performed.

(方案 1 )如果浊度检测值小于或等于预定的浊度阈值，则在漂洗程序中经过滤组件循环使用该洗衣用水。为便于区分描述，将循环使用洗涤程序中的洗衣用水对衣物进行漂洗的漂洗程序，也可称为循环洗涤或膜过滤漂洗程序。例如：水泵 6开启，第一换向阀 7转换至过滤管路 13，洗衣用水依次经水泵 6、送水管路 12、第一换向阀 7、过滤管路 13、过滤组件 9，回流管路 18进入内筒进行过滤漂洗。膜过滤漂洗完毕，进入过滤组件清洗阶段，第一换向阀 7关闭，第二换向阀 10打开，气泵 8开，气流经过过滤组件 9的滤膜，第二换向阀 10形成气洗回路进行气洗。气洗结束，气泵 8关闭，水泵 6开，第一换向阀 7和第二换向阀 10开，桶内的过滤水经水泵 6，送水管路 12，第一换向阀 7，过滤管路 13，过滤组件 9，清洗管路 17，第二换向阀 10，第二排水管路 16排放对过滤组件进行水洗。过滤组件清洗清洗完毕之后进行脱水排放。 (Scheme 1) If the turbidity detection value is less than or equal to a predetermined turbidity threshold, the laundry water is recycled through the filter assembly in the rinsing process. To facilitate the differentiation of the description, a rinsing procedure that circulates the laundry using the laundry water in the washing program may also be referred to as a cycle washing or membrane filtration rinsing procedure. For example: the water pump 6 is turned on, the first reversing valve 7 is switched to the filter line 13, and the washing water is sequentially passed through the water pump 6, the water supply line 12, the first reversing valve 7, the filter line 13, the filter assembly 9, the return line 18 enter the inner cylinder for filtration and rinsing. After the membrane filtration rinse is completed, the filter assembly cleaning stage is entered, the first reversing valve 7 is closed, the second reversing valve 10 is opened, the air pump 8 is opened, the airflow passes through the filter membrane of the filter assembly 9, and the second reversing valve 10 forms a gas washing circuit. Air wash. At the end of the air washing, the air pump 8 is closed, the water pump 6 is opened, the first reversing valve 7 and the second reversing valve 10 are opened, the filtered water in the tub is passed through the water pump 6, the water supply line 12, the first reversing valve 7, the filter tube The road 13, the filter assembly 9, the purge line 17, the second diverter valve 10, and the second drain line 16 discharge water for the filter assembly. After the filter assembly is cleaned and cleaned, it is dehydrated and discharged.

(方案 2 )如果浊度检测值大于预定的浊度阈值，则在漂洗程序中不经过滤组件循环使用该洗衣用水，可另将洗涤程序中内筒的洗衣用水排放至洗衣机外，向内筒中另进清水继续洗衣。如：水泵 6开启，第一换向阀 7和第二换向阀 10开，洗涤程序中内筒的洗衣用水经过送水管路 12、第一排水管路 15和第二排水管路 16排出，清水依次经过进水阀 1、洗涤剂盒 2 i¾A到内筒 3内，漂洗程序。 (Scheme 2) If the turbidity detection value is greater than the predetermined turbidity threshold value, the washing water is recycled in the rinsing process without passing through the filtering component, and the washing water of the inner cylinder in the washing program may be discharged to the outside of the washing machine, in the inner cylinder Into the clear water to continue the laundry. For example, the water pump 6 is opened, the first reversing valve 7 and the second reversing valve 10 are opened, and the washing water of the inner cylinder in the washing process is discharged through the water supply pipe 12, the first drainage pipe 15 and the second drainage pipe 16, The clean water passes through the inlet valve 1, the detergent box 2 i3⁄4A to the inner cylinder 3 in sequence, and the rinsing process.

可根据实际需要包括多次漂洗。该情形下，第 N-1次漂洗程序结束之后，通过浊度传感器检测洗衣用水的浊度，根据浊度检测值和预定的浊度阈值的比较结果，如果浊度检测值小于或等于浊度阈值，则经过滤组件循环使用该洗衣用水，控制方案参见上述（方案 1 ); 如果浊度检测值大于浊度阈值，则不经过滤组件循环使用该洗衣用水，将该洗衣用水排出洗衣机外，并另进清水以执行第 N次漂洗程序。控制方案参见上述（方案 2 )。如此循环控制，直至完成各次漂洗程序。 Multiple rinses can be included as needed. In this case, after the end of the N-1th rinsing procedure, the turbidity of the washing water is detected by the turbidity sensor, and if the turbidity detecting value is less than or equal to the turbidity, based on the comparison result of the turbidity detecting value and the predetermined turbidity threshold value. Threshold, the laundry water is recycled through the filter component, and the control scheme is as described above (Scheme 1); if the turbidity detection value is greater than the turbidity threshold, the laundry water is recycled without using the filter component, and the laundry water is discharged out of the washing machine. Additional water is added to perform the Nth rinsing procedure. See the above (Scheme 2) for the control scheme. This cycle is controlled until each rinsing process is completed.

总之，上述技术方案将温度检测值和浊度检测值共同作为是否循环使用洗衣用水的选择因素，由此在不损坏过滤组件、降低增加过滤组件过滤处理的负荷、满足衣物洗净率要求的基础上，尽可能的节省洗衣用水，实现了对洗衣机节水洗衣流程的智能控制，延长了过滤组件的使用寿命，降低洗衣机的维护成本。虽然已经详细说明了本发明及其优点，但是应当理解在不脱离由所附的权利要求所限定的本发明的精神和范围的情况下可以进行各种改变、替代和变换。 In summary, the above technical solution uses the temperature detection value and the turbidity detection value together as a selection factor for whether or not to recycle the laundry water, thereby reducing the load of the filtration component and reducing the load of the filter component and satisfying the requirement of the laundry washing rate.
