Description

Technical Field

[0001] The present invention relates to the field of washing machines, and in particular to a washing machine control method and a washing machine. Background Art

[0002] In order to save water, some patents have been disclosed that washing machines use circulating water to wash clothes. However, the existing patents mainly use the wastewater generated during washing in the washing machine, filter it and reuse it. Since this method of washing clothes with circulating water requires waiting for the wastewater generated during the washing process of the washing machine to be filtered, the waiting time is long.

[0003] At present, other devices outside the washing machine, especially water-related home appliances, such as water purifiers, water softeners, water purifiers, water heaters, etc., will generate filtered wastewater. At present, the filtered wastewater generated by other devices outside the washing machine is often not reused, but directly discharged, which causes energy waste. If the filtered wastewater generated by other devices outside the washing machine is applied to the inside of the washing machine and continues to supply water for washing after treatment, it will achieve the effect of saving energy and save more operation time than using the washing wastewater inside the washing machine to wash clothes.

[0004] In summary, when washing machines use circulating water to wash clothes, they generally use the wastewater generated during the washing and rinsing processes inside the washing machine for recycling, and the washing machine cannot use the wastewater filtered by other external equipment such as a water purifier to wash clothes. At present, there is a need for a washing machine control method that can use the filtered wastewater generated by other external equipment to supply water to the washing machine. At present, there is also a need for a washing machine suitable for the washing machine control method.

[0005] In view of the above problems, the present invention is proposed. Summary of the invention

[0006] The invention aims to provide a washing machine control method, which can use the filtered wastewater generated by other external equipment to wash clothes. Another object of the invention is to provide a washing machine suitable for the washing machine control method, which can use the wastewater generated by other external equipment to wash clothes.

[0007] The present invention provides a washing machine control method, wherein the water supply mode of the washing machine includes using filtered waste water from other equipment outside the washing machine for water supply. The present invention enables the washing machine to use filtered waste water from other equipment outside for water supply, thereby achieving the effect of saving energy.

[0008] Furthermore, when the washing machine is executing the water supply process, the user selects or the program determines whether the washing machine uses an external clean water source for water supply or uses filtered waste water from other equipment outside the washing machine for water supply. This setting allows the user to independently select or use the program to directly determine whether to use filtered waste water from other external equipment to supply water to the washing machine.

[0009] Furthermore, when choosing to use the filtered wastewater from other equipment outside the washing machine for water supply, detect and determine whether the filtered wastewater from other equipment outside the washing machine meets the conditions for normal water supply to the washing machine; when the water supply conditions are met, start the filtered wastewater supply process of the filtered wastewater from other equipment outside the washing machine to supply water to the washing machine; otherwise, start the normal water supply process of the clean water source outside the washing machine to supply water to the washing machine. When the user chooses to use the filtered wastewater from other equipment outside the washing machine for water supply, if the filtered wastewater from other equipment is insufficient or inconvenient to connect to the washing machine, the user may not be able to connect the washing machine with the filtered wastewater from other external equipment for water supply. The control method of the present invention allows the washing machine to be controlled to continue washing using the external clean water source when the above situation occurs, and the control method is reasonably set.

[0010] Furthermore, when executing the filtered wastewater supply process, the washing machine can switchably connect the filtered wastewater of various different external other devices to the water supply water channel; a variety of washing programs are set in the washing machine, including at least pre-washing, hot water washing, and sterilization washing, and the washing machine can perform the filtered wastewater intake process when executing different washing programs; before performing the filtered wastewater supply process, according to the washing program executed by the washing machine, the user is prompted to connect the washing machine to the filtered wastewater of a specific device to the water supply water channel. Because different washing programs have different water supply requirements, and the water quality of filtered wastewater generated by different external other devices is also different, the user is reasonably prompted to connect to a specific external other device according to the washing program, so that the filtered wastewater provided by other external devices is more suitable for the needs of the washing program to be executed.

[0011] Furthermore, before the filtered wastewater supply process is carried out, the filtered wastewater is directly used and / or filtered and / or heated and / or pressurized according to the washing program executed by the washing machine and other external devices connected to the washing machine water supply waterway, and the treated filtered wastewater is used to supply water to the washing machine. A reasonable filtered wastewater treatment method is selected according to the washing program to be executed by the washing machine and other external devices connected to the washing machine, so that the quality of the filtered wastewater supplied to the washing machine is more suitable for the needs of the washing program to be executed.

[0012] Furthermore, the washing machine control method comprises the following steps:

[0013] Step S1, before the washing machine performs any washing program and supplies water, the user selects a water supply method according to the needs. If the user selects to use an external clean water source for water supply, step S2 is executed; if the user selects to use filtered waste water from other equipment outside the washing machine for water supply, step S3 is executed;

[0014] Step S2, using an external clean water source to supply water to the washing machine and continuing to perform the washing program;

[0015] Step S3, detecting and judging whether the filtered waste water of other equipment outside the washing machine meets the conditions for normal water supply to the washing machine, if it meets the conditions, executing step S4, otherwise executing step S6;

[0016] Step S4, according to the washing program executed by the washing machine, prompting the user to connect the washing machine with the filtered waste water of the specific device through the water supply channel, and then executing step S5;

[0017] Step S5, performing different treatments on the filtered wastewater according to the washing program executed by the washing machine and other external devices connected to the water supply channel of the washing machine, and using the treated filtered wastewater for water supply;

[0018] Step S6, using an external clean water source to supply water to the washing machine, and continuing the washing process.

[0019] Furthermore, when the washing machine needs to run a pre-washing program, the washing machine is controlled to prompt the user to connect the washing machine's water supply circuit with the filtered wastewater of the water purifier and / or water softener and / or water purifier; after the washing machine's water supply circuit is connected with the filtered wastewater of the water purifier and / or water softener and / or water purifier, the washing machine is controlled to directly introduce the filtered wastewater of the water purifier and / or water softener and / or water purifier into the washing machine for pre-washing water supply. Since the pre-washing program is a rough wash of clothes, other fine washing programs are often performed after the pre-washing, so the water quality requirements are relatively low, and it is only necessary to use the filtered wastewater of the water purifier and / or water softener and / or water purifier to directly supply water to the washing machine, so as to achieve the effect of convenient operation and energy saving.

[0020] Furthermore, when the washing machine needs to perform hot water washing and / or sterilizing washing, the washing machine is controlled to prompt the user to connect the water supply circuit of the washing machine with the filtered waste water of the water heater; after the water supply circuit of the washing machine is connected with the filtered waste water of the water heater, the washing machine is controlled to filter the filtered waste water of the water heater, and the filtered waste water after filtering is guided to the washing machine for hot water washing and / or sterilizing washing. Since the water temperature requirement is high when performing hot water washing and / or sterilizing washing, and the filtered waste water in the water heater itself has a certain temperature, when the filtered waste water of the water heater is used to supply water for hot water washing and / or sterilizing washing, the energy consumption required for heating the water supply can be reduced, thereby achieving the effect of energy saving and water saving.

[0021] Furthermore, after controlling the washing machine to filter the filtered waste water of the water heater, the turbidity, water quality and water temperature of the filtered waste water are detected; when the turbidity, water quality and water temperature meet the requirements, the filtered waste water is guided to the washing machine for hot water washing and / or sterilization washing; when the turbidity and water quality meet the requirements, but the water temperature is lower than the required water temperature, the filtered waste water is heated to the required water temperature and then guided to the washing machine for hot water washing and / or sterilization washing; when the turbidity and water quality meet the requirements, but the water temperature is higher than the required water temperature, the filtered waste water is allowed to stand until the water temperature drops to the required water temperature and then guided to the washing machine for hot water washing and / or sterilization washing; when the turbidity and water quality do not meet the requirements, the washing machine is controlled to use an external clean water source to supply hot water washing and / or sterilization washing. Since the hot water washing and / or sterilization washing is in the fine washing stage, there are certain requirements for the water quality and the water temperature; therefore, it is necessary to filter the filtered waste water of the water heater, and to detect whether the quality and water temperature of the filtered waste water after the filtration treatment meet the requirements, so as to ensure that the water supply for hot water washing and / or sterilization washing is qualified.

[0022] The present invention also provides a washing machine, which is applicable to the above-mentioned washing machine control method, and includes a water inlet pipe for supplying water to the washing machine, the water inlet pipe can be connected to the filtered wastewater chamber of other equipment outside the washing machine, and the water inlet pipe is also connected to a device for treating the filtered wastewater. The washing machine provided by the present invention can achieve the effect of using the filtered wastewater of other external equipment for water supply.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0024] 1) The washing machine control method provided by the present invention enables the washing machine to utilize filtered waste water from other external equipment for washing to achieve the effect of saving energy.

[0025] 2) The control method of the washing machine provided by the present invention, when using the filtered wastewater of other equipment outside the washing machine for water supply, if the other equipment outside is not convenient to be connected with the water supply waterway of the washing machine, or if there is less filtered wastewater from other equipment outside, that is, when the filtered wastewater from other equipment outside is not suitable for supplying water to the washing machine, the washing machine is controlled to use the external clean water source for normal water supply. This setting is more reasonable and can ensure the normal operation of the washing program of the washing machine.

[0026] 3) The washing machine control method provided by the present invention can prompt the user to use the filtered wastewater of different external devices for washing according to the different washing programs that the washing machine needs to execute, and set the corresponding filtered wastewater treatment method. That is, according to the characteristics of the washing program that the washing machine needs to execute, the filtered wastewater of the appropriate external device is selected for water supply and a reasonable filtered wastewater treatment method is set, so that the use of filtered wastewater can be more reasonable. For example, when the washing machine performs a pre-washing program, since it is just a simple rough wash and then other washing programs will be performed, it is only necessary to use the filtered wastewater in the water purifier and other equipment for direct pre-washing; and when the washing machine needs to perform a rinsing program, since the requirements for rinsing water are high, it is necessary to filter the filtered wastewater in the water purifier and other equipment before rinsing.

[0027] 4) When the present invention is performing the pre-washing procedure, the user is prompted to connect the water supply channel of the washing machine with the filtered waste water of the water purifier and / or water softener and / or water purifier, and directly introduce the filtered waste water of the water purifier and / or water softener and / or water purifier into the washing machine for pre-washing. Since pre-washing is a rough wash and has a relatively low requirement for water quality, the requirement can be met by directly using the filtered waste water of the water purifier and / or water softener and / or water purifier, making the water supply operation for pre-washing simple and energy-saving.

[0028] 5) When performing hot water washing and / or sterilizing washing, the present invention prompts the user to connect the water supply waterway of the washing machine and the filtered wastewater of the water heater. Since hot water washing and / or sterilizing washing have high requirements for water temperature, and the filtered wastewater in the water heater itself has a certain temperature, the filtered wastewater of the water heater is used to supply water for hot water washing and / or sterilizing washing, which can reduce the energy consumed by heating water supply and achieve energy saving and water saving effects. And since hot water washing and / or sterilizing washing belong to fine washing procedures, there are certain requirements for water quality and water temperature, so it is necessary to filter the filtered wastewater of the water heater, and detect the water quality and water temperature of the filtered wastewater after filtering. Filtered wastewater with unqualified water quality cannot be used as a water supply source, and filtered wastewater with unqualified water temperature needs to be further treated to make the water temperature qualified before use; such a setting can ensure that the water supply for hot water washing and / or sterilizing washing meets the requirements, thereby ensuring the effect of hot water washing and / or sterilizing washing.

[0029] 6) The present invention also provides a washing machine, which can utilize filtered waste water from other external devices to supply water to the washing machine through the configuration of the internal structure of the washing machine.

DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] Example 1

[0038] In order to save water, some existing patents of washing machines can recycle the waste water generated by internal washing, but there is a lack of patents that use filtered waste water generated by other equipment outside the washing machine for washing. Therefore, this embodiment provides a washing machine control method that can reasonably use the filtered waste water generated by other equipment outside the washing machine to supply water to the washing machine.

[0039] The washing machine control method provided by the present invention sets a variety of water supply methods for the washing machine, including normal water supply from an external clean water source and water supply using filtered waste water from other equipment outside the washing machine. The washing machine is normally supplied with water from an external clean water source, including using tap water to supply the washing machine and using clean water in a water storage container to supply the washing machine. The arrangement of the present invention allows the user to independently select or the program to determine the appropriate water supply method when executing different washing programs of the washing machine. And by setting up the use of filtered waste water from other equipment outside the washing machine for water supply, the washing machine can use filtered waste water from other equipment to achieve the effect of saving energy. The washing programs in the washing machine include pre-washing, hot water washing, sterilization washing, etc. Many washing programs require water to be supplied to the washing machine to complete washing. For example Figure 1 As shown in , when the washing machine executes any washing program and needs water supply, it can be selected by the user or determined by the program as needed to choose to use an external clean water source or filtered waste water from other equipment outside the washing machine.

[0040] When the user chooses to use the filtered wastewater from other devices outside the washing machine for water supply, the user may find that the filtered wastewater from other external devices is not convenient to connect to the water supply waterway of the washing machine, or the amount of filtered wastewater from other external devices is too small to be suitable for supplying water to the washing machine. In the above case, the filtered wastewater from other external devices may not be used to supply water to the washing machine. Figure 1 As shown in , the washing machine detects and determines whether the filtered wastewater of other external equipment can supply water to the washing machine normally. For example, within the set time, it is detected whether the water supply waterway of the washing machine is connected to the filtered wastewater of other external equipment; if it is detected that the washing machine is connected to the filtered wastewater of other external equipment for the water supply waterway, the washing machine is controlled to use the filtered wastewater for water supply; otherwise, the washing machine is controlled to use the external clean water source for normal water supply. That is, when it is not suitable to use the filtered wastewater of other external equipment for water supply, the user only needs not to connect the filtered wastewater of other external equipment with the water supply waterway of the washing machine. When the set time is reached, the washing machine will automatically determine that it is impossible to use the filtered wastewater of other external equipment to supply water to the washing machine, and control the clean water source outside the washing machine to supply water to the washing machine to ensure that the washing machine runs the washing program normally. After the water supply waterway of the washing machine is connected to the filtered wastewater chamber of other external equipment, it can also detect whether the filtered wastewater of other external equipment is sufficient to supply water to the washing machine by setting a water level detection device. When the amount of filtered wastewater of other external equipment is small, the washing machine is controlled to use the external clean water source to supply water to the washing machine. This setting is more reasonable and can ensure that the washing machine can perform the washing program normally under any circumstances.

[0041] When the filtered wastewater from other external devices meets the conditions for supplying water to the washing machine, the washing machine can be connected to the filtered wastewater from a variety of different external devices through the water supply waterway. For example, the water supply waterway of the washing machine can be switched to be connected to the filtered wastewater from a large number of household water-circuit appliances such as water purifiers, water softeners, and water purifiers, so as to achieve the effect of using filtered wastewater to save water. Figure 1 As shown in , according to the washing program that the washing machine needs to execute, the user is prompted to connect the water supply circuit of the washing machine with the filtered wastewater of a specific device. The washing machine needs to execute different washing programs, and the quality requirements for the water supply source are different. For example, when performing rough washing programs such as pre-washing, since it is just a simple cleaning before other washing programs, the quality requirements for the water supply source are relatively low; when performing rinsing and other programs, since rinsing itself is to clean the clothes with foam, the quality requirements for the water supply source are high and the water supply needs to be relatively clean. The quality of the filtered wastewater of different external other equipment is also different. Therefore, according to the different washing programs that the washing machine needs to execute, it is possible to reasonably select the filtered wastewater connected to different external other equipment, so that the selected filtered wastewater of other external equipment is more suitable for the washing program to be executed, thereby making the application of filtered wastewater more reasonable.

[0042] like Figure 1 As shown in , after the water supply circuit of the washing machine is connected to the filtered waste water of other external equipment, the washing machine is controlled to set different treatment methods for the filtered waste water according to the washing program to be executed and the other external equipment connected to the water supply circuit. As can be seen from the above, different washing programs have different requirements on the quality of the water supply source. Even when executing certain specific washing programs, the water quality of the water supply source is required to be relatively clean and / or the water flow is relatively turbulent and / or the water temperature is relatively high. Therefore, the filtered waste water directly introduced at this time may not meet the requirements. This requires that the introduced filtered waste water be treated. Different treatment methods for filtered waste water include: direct use treatment, filtering treatment, heating treatment, and pressurized treatment. As mentioned above, different washing programs have different requirements on the quality of the water supply, and the quality of the filtered waste water of different external equipment is also different. Therefore, a more reasonable control method is as follows: Figure 1 As shown in , the treatment method for the filtered wastewater is selected according to the washing program to be executed and other external equipment connected to the water supply channel.

[0043] This embodiment takes the washing machine executing the pre-washing program as an example to illustrate how to reasonably use the filtered wastewater of other equipment outside the washing machine to supply water to the washing machine according to the control method provided in this embodiment. When the washing machine needs to execute the pre-washing program, the washing machine is controlled to prompt the user to connect the water supply waterway of the washing machine with the filtered wastewater of the water purifier and / or water softener and / or water purifier. Since the pre-washing is a rough washing program with lower requirements on the quality of the water supply and no special requirements on the water supply such as high temperature, the filtered wastewater of the more commonly used household electrical appliance water purifier and / or water softener and / or water purifier can be used to supply water to the washing machine.

[0044] When the user connects the filtered wastewater of the water purifier and / or water softener and / or water purifier to the water supply of the washing machine, the washing machine is controlled to directly introduce the filtered wastewater of the water purifier and / or water softener and / or water purifier into the washing machine for pre-washing water supply; after the pre-washing program is completed, the washing machine is controlled to discharge the filtered wastewater, and use clean water to perform other washing programs on the clothes. From the above, it can be seen that the quality of the water supply for the pre-washing program is relatively low. In order to save energy, there is no need to perform any treatment on the filtered wastewater, and it can be directly used for pre-washing. Since the pre-washing is only a rough wash, it is necessary to use clean water from an external water source to perform a fine wash program on the clothes to ensure the quality of the washed clothes. That is, the solution provided in this embodiment of using filtered wastewater from other external equipment for water supply when executing the pre-washing program is reasonably designed and can save energy while ensuring the washing effect.

[0045] Example 2

[0046] This embodiment provides a washing machine control method based on the above embodiment. The washing machine control method provided in this embodiment takes the washing machine needing to execute hot water washing and / or sterilization washing as an example.

[0047] When the washing machine needs to perform hot water washing and / or sterilization washing, the washing machine is controlled to prompt the user to connect the washing machine with the filtered waste water of the water heater through the water supply waterway. Since the water supply requirement for hot water washing and / or sterilization washing is high water temperature, the use of high temperature water during sterilization washing can have a certain sterilization effect. And since the filtered waste water in the water heater sometimes has a certain water temperature, the filtered waste water in the water heater can be used when hot water washing and / or sterilization washing require a high water supply temperature.

[0048] And because hot water washing and / or sterilization washing belong to fine washing procedures, the water supply quality requirements for washing are relatively high when hot water washing and / or sterilization washing are performed. When hot water washing and / or sterilization washing are required and the filtered wastewater connected to the water heater is supplied, the washing machine is controlled to filter the filtered wastewater of the water heater, and the filtered wastewater after filtering is guided to the washing machine for hot water washing and / or sterilization washing. That is, the filtered wastewater drawn from the water heater needs to be re-filtered. And the quality of the filtered wastewater needs to be tested after re-filtration. After the washing machine is controlled to filter the filtered wastewater of the water heater, the turbidity, water quality and water temperature of the filtered wastewater are tested. Only when the turbidity, water quality and water temperature of the filtered wastewater meet the requirements for hot water washing and / or sterilization washing, the filtered wastewater can be introduced into the washing machine for hot water washing and / or sterilization washing. The requirements for water quality, such as turbidity and water quality, depend on the quality of the filtered wastewater in the water heater. When the quality of the filtered wastewater is poor, even after re-filtration, the water quality of the filtered wastewater may not meet the requirements. In order to ensure the quality of washing, the filtered wastewater of the water heater can only be abandoned for water supply. If the water temperature does not meet the requirements, the water temperature itself can be adjusted. You only need to adjust the temperature of the filtered wastewater to a suitable temperature and then use the filtered wastewater of the water heater for water supply.

[0049] Specifically: when the turbidity, water quality and water temperature meet the requirements, the filtered waste water is guided into the washing machine for hot water washing and / or sterilization washing; when the turbidity and water quality meet the requirements, but the water temperature is lower than the required water temperature, the filtered waste water is heated to the required water temperature and then guided into the washing machine for hot water washing and / or sterilization washing; when the turbidity and water quality meet the requirements, but the water temperature is higher than the required water temperature, the filtered waste water is allowed to stand until the water temperature drops to the required water temperature and then guided into the washing machine for hot water washing and / or sterilization washing; when the turbidity and water quality do not meet the requirements, the washing machine is controlled to use an external clean water source to supply hot water washing and / or sterilization washing.

[0050] The present embodiment provides a solution for using the filtered waste water of the water heater to supply water for hot water washing and / or sterilization washing during the hot water washing and / or sterilization washing of the washing machine. With the help of the temperature of the filtered waste water in the water heater itself, the heating consumption for the water supply during hot water washing and / or sterilization washing can be reduced, thereby achieving the effect of saving energy. In addition, when using the filtered waste water of the water heater to supply water for hot water washing and / or sterilization washing, the filtered waste water is reasonably tested to ensure that the filtered waste water of the water heater meets the quality requirements of the water supply for hot water washing and / or sterilization washing before supplying water, thereby further ensuring the quality of washing.

[0051] Example 3

[0052] This embodiment provides a washing machine suitable for the above-mentioned washing machine control method on the basis of the above-mentioned embodiment. The washing machine provided in this embodiment includes a water inlet pipe 2 for supplying water to the washing machine, and the water inlet pipe 2 can be connected to the filter wastewater chamber 3 of other equipment outside the washing machine, and a device for treating the filtered wastewater is also connected to the water inlet pipe 2. That is, by setting the water inlet pipe 2 that can extend to the outside of the washing machine, the filter wastewater chamber 3 of other external equipment can be connected by the water inlet pipe 2, so that the washing machine can use the filtered wastewater of other external equipment to supply water to the washing machine. When in use, the user only needs to insert the water inlet pipe 2 into the filter wastewater chamber 3 of other equipment outside the washing machine, which can be connected manually or automatically.

[0053] like Figure 2 As shown in the figure, this embodiment also provides a specific scheme for setting a washing machine to connect with other external equipment to filter wastewater chamber 3. The washing machine includes an inner barrel 8 for washing clothes, a liquid storage container 1 for supplying water to the inner barrel 8, and the liquid storage container 1 is provided with a water supply inlet pipe 2, which extends to the outside of the liquid storage container 1 and is sequentially connected with a first water valve 9, a liquid detection device, a circulating filter pump 7, and a filter wastewater chamber 3 of other equipment outside the washing machine. That is, the washing machine of this embodiment is provided with a liquid storage container 1, and the liquid storage container 1 is used to store the filtered wastewater in other external equipment that supplies water to the washing machine. The liquid storage container 1 can be used to store the filtered wastewater when it is not washed. The first water valve 9 and the liquid detection device are arranged near the liquid storage container 1 on the water inlet pipe 2, so that it can be judged whether to store the filtered wastewater in the liquid storage container 1 by detecting the quality of the filtered wastewater, so that only the filtered wastewater that meets the quality requirements can be stored in the liquid storage container 1. Among them, the liquid detection device is connected to the first water valve 9; the liquid detection device includes a turbidity detection element 5, a water quality detection element 6, a water temperature detection element, etc.

[0054] Liquid level detection elements are provided in the inner barrel 8 and the liquid storage container 1; the liquid storage container 1 is provided with a drain pipe 10, and the filtered wastewater stored in the liquid storage container 1 is supplied to the inner barrel 8 by the drain pipe 10. The drain pipe 10 extends to the outside of the liquid storage container 1 and is connected to the circulation pump 11, the second water valve 12, and the inner barrel 8 in sequence; all liquid level detection elements are connected to the circulation pump 11 and the second water valve 12 respectively. Since the filtered wastewater has been filtered by the filter circulation pump 7 before entering the liquid storage container 1, when the drain pipe 10 discharges the filtered wastewater into the inner barrel 8, it is not necessary to filter it again, and only the circulation pump 11 is required. The setting of the liquid level detection elements and the second water valve 12 in the inner barrel 8 and the liquid storage container 1 makes it possible to judge whether water is supplied to the inner barrel 8 through the drain pipe 10 through the water levels in the inner barrel 8 and the liquid storage container 1.

[0055] like Figure 2As shown in the figure, the inner barrel 8 is connected to the tap water pipe 13, and a third water valve 14 is arranged between the tap water pipe 13 and the inner barrel 8; the liquid level detection element in the inner barrel 8 and the liquid storage container 1 is connected to the third water valve 14. Through the arrangement of the liquid level detection element in the inner barrel 8, the liquid storage container 1 and the third water valve 14, when the water level is still not enough for washing after the filtered waste water is injected into the inner barrel 8, or when the liquid level in the liquid storage container 1 is insufficient, the tap water pipe 13 can be controlled by the third water valve 14 to supply water to the washing machine. In this embodiment, multiple water valves 4 can also be combined into a multi-way water valve to control the use of filtered waste water or tap water to supply water to the inner barrel 8.

[0056] The arrangement of the washing machine in this embodiment enables the washing machine to be connected to other external devices to filter the waste water chamber 3, and the filtered waste water can be used to supply water to the washing machine, thereby achieving the effect of saving water.

[0057] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
