Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and in particular relates to a control method of a clothing processing device and the clothing processing device. Background Art

[0002] Water on the earth is constantly circulating and changing. However, freshwater resources are not inexhaustible, but the most precious and irreplaceable natural resources. my country is a country with uneven distribution of freshwater resources. In daily life, as soon as we turn on the tap, water flows out continuously, and we may not feel the water crisis at all. But in fact, some areas in my country are already in a state of serious water shortage, and the water we depend on for survival is also becoming increasingly scarce. At present, there are more than 1 billion people in the world who do not have access to clean water, and 3.1 million people die every year from illnesses caused by drinking unclean water.

[0003] Improving the utilization rate of water resources and reducing water waste are effective ways to save water. The key to effective water conservation is to use "recycled water" to achieve water resource reuse. If the use of recycled water can be adopted throughout society, it will not only bring considerable economic and environmental benefits, but also create a good atmosphere of cherishing water resources in society.

[0004] With the continuous improvement of people's living standards, washing machines have become one of the essential electrical appliances in every household. Washing machines are also household appliances with high water consumption. Therefore, improving the water-saving performance of washing machines is an important research and development direction for major manufacturers at this stage.

[0005] A Chinese patent with application number CN202221238742.4 provides a drum washing machine, which includes a casing, a washing basin with a bottom recessed into the casing at the upper end of the casing, a water outlet at the bottom of the washing basin, and the water outlet is connected to the drain pipe of the drum washing machine through a drainage pipe. Clothes to be washed can be placed in the washing basin at the upper end of the casing of the drum washing machine for local washing, and the sewage in the washing basin can be discharged into the drain pipe of the drum washing machine through the drainage pipe to prevent the sewage from flowing through the drum and causing secondary contamination to the clothes in the drum.

[0006] In the above scheme, the water is not classified according to its degree of dirtiness, but is directly discharged. If the washing water is relatively clean, it can be reused. Discharging it directly will cause a waste of water resources.

[0007] In view of this, the present invention is proposed. Summary of the invention

[0008] The main purpose of the present invention is to solve the above technical problems and to provide a control method of a clothes processing device and a clothes processing device.

[0009] To achieve the above object, the technical solution of the present invention is:

[0010] In a first aspect, the present invention provides a control method for a clothes processing device, wherein the clothes processing device uses all or part of the recycled water for washing or rinsing, and the control method specifically comprises:

[0011] Obtain water quality information of reclaimed water;

[0012] determining whether to use the grey water to wash or rinse the clothes in the clothes processing device according to the water quality information;

[0013] The water quality information at least includes the turbidity and chromaticity of the reclaimed water.

[0014] Furthermore, if the turbidity of the reclaimed water is greater than or equal to the first set value, the reclaimed water is directly discharged; if it is less than the first set value, the next step is performed;

[0015] If the chromaticity of the medium water is less than the second set value, the medium water is used to wash or rinse the clothes in the clothes processing device; if the chromaticity of the medium water is greater than or equal to the second set value, the next step is performed;

[0016] The clothes processing device determines whether to use the recycled water to wash or rinse the clothes in the clothes processing device according to the received instruction.

[0017] Further, the clothes processing device sends a prompt to the user, and the user sends an instruction to the clothes processing device whether to use the recycled water to wash or rinse the clothes in the clothes processing device;

[0018] Alternatively, the clothing processing device compares the color of the clothes washed last time and this time, or the color of the recycled water and the clothes washed this time. If the colors are the same, an instruction is issued to use the recycled water to wash or rinse the clothes in the clothing processing device; if the colors are different, an instruction is issued to directly discharge the recycled water.

[0019] Furthermore, if the grey water is used for washing or rinsing original clothes, an instruction to use the grey water to wash or rinse the clothes in the clothes processing device is issued.

[0020] Furthermore, the waiting time between the generation of the grey water and its use by the clothes processing device is less than or equal to a set time. If the waiting time reaches the set time, the grey water is directly discharged.

[0029] 2. The control method of the clothing treatment device of the present invention obtains the water quality information of the grey water and determines whether to use the grey water to wash or rinse the clothes based on the water quality information. This ensures that the clothes are in a good washing environment and avoids damage to the clothes or influence on the washing effect due to water quality problems. By setting the thresholds of turbidity and chromaticity and selectively using or discharging the grey water, it can effectively avoid the situation that the grey water with poor water quality is still used to wash clothes, thereby ensuring the washing quality.

[0030] 3. The control method of the clothes treatment equipment of the present invention takes into account the timeliness of the use of grey water, and sets the waiting time for the use of grey water within the set time. If this time is exceeded, the grey water will be directly discharged. This can avoid the increase of harmful substances in the grey water due to long waiting time, thereby affecting its use quality.

[0031] 4. The laundry treatment device of the present invention is equipped with a water quality detection module of a turbidity sensor and a colorimetric sensor, and a water storage tank for containing grey water, which has good practicality.

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The accompanying drawings are part of the present invention and are used to provide a further understanding of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but do not constitute an improper limitation of the present invention. Obviously, the accompanying drawings described below are only some embodiments. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without creative work. In the accompanying drawings:

[0033] Figure 1It is a flow chart of the present invention.

[0034] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but are intended to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] [Example 1]

[0037] This embodiment provides a control method for a clothes processing device, and the clothes processing device in this specification includes but is not limited to various forms of washing machines and shoe washing machines. Further, the clothes processing device can use all or part of the recycled water for washing or rinsing, and the recycled water refers to the water that has been used, especially the washing water or rinsing water that has been used. When the recycled water is sufficient for this use, all the recycled water is used for washing or rinsing. When the recycled water is insufficient for this use, the insufficient part can be supplemented with clean water.

[0038] The control method specifically includes:

[0039] Obtain water quality information of reclaimed water;

[0040] determining whether to use the grey water to wash or rinse the clothes in the clothes processing device according to the water quality information;

[0041] Water quality information includes at least the turbidity and color of the reclaimed water.

[0042] Among them, turbidity can reflect the impurity content of the reclaimed water, and the turbidity value is positively correlated with the impurity content; chromaticity can reflect the quantitative degree of the color of the reclaimed water, and the larger the chromaticity, the darker the color. It should be noted that since clothes often use a variety of pigments and dyes, especially dark clothes will inevitably fade when washed with water, and dyed reclaimed water does not necessarily have a lot of impurities. If reclaimed water with a high degree of dyeing is used to wash or rinse light-colored clothes, it will cause the light-colored clothes to be stained. However, if it is used for the same piece of clothing or clothes of the same color system, there will be no staining problem. Therefore, this description proposes a new idea for the recycling of reclaimed water.

[0043] Furthermore, the turbidity of the reclaimed water is measured before it is reused. If the turbidity of the reclaimed water is greater than or equal to the first set value, it means that the impurity content in the reclaimed water is high, and it is difficult to achieve the effect of cleaning clothes if it is reused. In this case, the reclaimed water is directly discharged; if the turbidity of the water is less than the first set value, it means that the impurity content in the reclaimed water is small and it is relatively clean, and it can be used for washing clothes or rinsing next time, and the next step is carried out at this time;

[0044] The chromaticity of the recycled water is measured. If the chromaticity of the recycled water is less than the second set value, it means that the recycled water is lighter in color, and such water has a lower risk of staining, and can be used to wash and rinse most clothes. In this case, the recycled water is used to wash or rinse the clothes in the clothes processing device. If the chromaticity of the recycled water is greater than or equal to the second set value, it means that the recycled water is darker in color and is not suitable for washing or rinsing light-colored clothes. In this case, the next step is performed.

[0045] The laundry processing device decides whether to use the recycled water to wash or rinse the laundry in the laundry processing device according to the received instruction. It should be noted that the above first setting value and second setting value can be the preferred values ​​obtained by analyzing big data or experimental results, or can be adjusted or set by the user according to his own preferences, which is not limited here.

[0046] Furthermore, the clothing processing device sends a prompt to the user through a display screen, voice, or mobile phone APP, and the user decides whether to use the recycled water for the next step of washing or rinsing based on experience, and sends an instruction to the clothing processing device through a display screen, voice, or mobile phone APP, whether to use the recycled water to wash or rinse the clothes in the clothing processing device;

[0047] Alternatively, the clothing treatment device compares the color of the last and current washing clothes or the color of the recycled water and the current washing clothes. If the two colors are the same, it will issue an instruction to use the recycled water to wash or rinse the clothes in the clothing treatment device. If the two colors are different, it will issue an instruction to directly discharge the recycled water. Specifically, the clothing treatment device is provided with a camera module. Each time the clothing treatment device is started and the clothes are put in, the camera module will be started. The control system module will obtain the captured image and analyze and store the color of the clothes. Before using the recycled water, the clothing treatment device compares the colors of the current clothes and the clothes that produce the recycled water, or compares the colors of the recycled water and the current clothes to find out whether the two are of the same color.

[0048] In some embodiments, the grey water may be used for washing or rinsing the original clothes, and the color comparison may be omitted to simplify the steps. For example, the method for determining whether the grey water is used for the original clothes may be that after the grey water is generated, the door of the clothes treatment device has not been opened, and it can be determined that the grey water is currently used for washing or rinsing the original clothes.

[0049] In some embodiments, the waiting time between the generation of grey water and its use by the clothing treatment device is less than or equal to the set time. If the waiting time reaches the set time, the grey water is directly discharged. The longer the grey water is retained, the easier it is for bacteria, viruses and other substances to grow, which will cause secondary pollution to the clothing and is not good for the health of the user. Therefore, the grey water is discharged after the set time is reached to avoid the increase of harmful substances in the grey water due to long waiting time.

[0050] [Example 2]

[0051] This embodiment provides a clothes processing device, which adopts the control method of the clothes processing device in Embodiment 1.

[0052] Furthermore, the clothing processing device is provided with a water quality detection module for detecting the quality of the grey water; the water quality detection module at least includes a turbidity sensor and a chromaticity sensor.

[0053] In some embodiments, the clothes treating apparatus has a water storage tank for containing grey water, and the water storage tank is connected to a water inlet and a water outlet of the clothes treating apparatus through pipes.

[0054] The water tank can be arranged outside the clothes processing device, or arranged inside the clothes processing device, but no matter where it is arranged, it is preferred that a transparent observation window is provided on the water tank or the clothes processing device so that the user can observe the color of the water in the water tank.

[0055] Preferably, the water quality detection module is disposed in the water storage tank, and after obtaining the water quality information of the grey water, it is determined whether to use the grey water to wash or rinse the clothes in the clothes processing device according to the water quality information.

[0056] Preferably, the clothes processing device is also provided with a water tank cleaning program, and the water tank is cleaned regularly or at a time selected by the user.

[0057] More preferably, after each user laundry program of the clothing processing device ends, a water tank cleaning program is added before the program ends. Specifically, it is determined whether the water tank is used in this washing program. If the water tank has been used, the water tank is automatically cleaned. If the water tank is not used in this washing program, the water tank cleaning program is skipped.

[0058] In some embodiments, the grey water comes from the clothes processing device itself and / or other washing devices. Further, the other washing devices are connected to the clothes processing device, or the other washing devices are integrated with the clothes processing device.

[0059] Specifically, the clothing processing device can be a single device, such as a separate washing machine, which produces grey water after washing or rinsing. After water quality monitoring, it is determined whether the grey water can be reused for the next washing or rinsing.

[0060] The clothing processing device may also be a combination of multiple devices, such as a combination of two washing machines, which may be two interconnected washing machines or an integrated dual-system washing machine. The first washing machine generates grey water after washing or rinsing, and the grey water is monitored for water quality to determine whether it can be reused for washing or rinsing in itself or in the second washing machine. In this case, it is preferred that the clothing processing device is provided with a camera module, and the clothing processing device compares the color of the current clothing and the clothing that generates the grey water, or the color of the current clothing and the grey water, to decide whether to use the grey water for washing or rinsing.

[0061] When the clothing processing device is a combination of multiple devices, it may also be a combination of a hand-washing tank and a washing machine. Preferably, the hand-washing tank is integrally provided on the washing machine, and the drainage pipe of the hand-washing tank is connected to the water inlet and outlet pipes of the washing machine. Sometimes the user washes part of the clothing by hand in the hand-washing tank and then puts it into the washing machine for automatic washing. Sometimes the user washes some small pieces of clothing by hand and washes other clothes in the washing machine. When the user finishes hand washing, he can visually observe the water quality of the hand washing water, and can decide by himself and operate on the device whether to use the reclaimed water for washing or rinsing in the washing machine below according to the actual situation. In this case, it is the user's priority to decide whether to use the reclaimed water for washing or rinsing.

[0062] Of course, grey water can also come from a variety of the same or different devices, and is not limited to washing equipment. The device is not necessarily connected to the clothing processing equipment. For example, the user can manually add grey water used for hand washing clothes into the water storage tank, and use the water quality detection module to determine whether to use the grey water for washing or rinsing.

[0063] The beneficial effects of the present invention are:

[0064] 1.

This ensures that the clothes are in a good washing environment and avoids damage to the clothes or influence on the washing effect due to water quality problems. By setting the thresholds of turbidity and chromaticity and selectively using or discharging the grey water, it can effectively avoid the situation that the grey water with poor water quality is still used to wash clothes, thereby ensuring the washing quality.

[0066] 3. The control method of the clothes treatment equipment of the present invention takes into account the timeliness of the use of grey water, and sets the waiting time for the use of grey water within the set time. If this time is exceeded, the grey water will be directly discharged. This can avoid the increase of harmful substances in the grey water due to long waiting time, thereby affecting its use quality.
