Technical Field

[0001] The present invention relates to the technical field of washing machines, and in particular provides a washing machine with an auxiliary water inlet and outlet device and a control method thereof. Background Art

[0002] Most washing machines on the market currently have a water inlet and a drain. When washing / rinsing, a certain amount of water is first injected into the washing drum through the water inlet and then the washing / rinsing operation is performed. After the operation is completed, the water is discharged through the drain. The fixed drain and water inlet affect the water intake and drainage efficiency of the washing machine, and thus affect the washing time. The washing machine takes a long time to intake water during the water intake stage, especially when the water pressure is insufficient, which affects the user experience; and it also takes a long time to drain water during the drainage stage. The time for the water intake and drainage stages is invalid time for the washing process. Therefore, by minimizing the time required for water intake and drainage, the efficiency of the washing machine can be improved and the user experience can be improved.

[0003] Currently, most washing machines improve the efficiency of water intake and drainage through program design. The optimization effect of this method is limited; that is, the optimization can only be achieved to a certain extent through program improvement; however, the improvement of the structure of the water intake and drainage device combined with program control can achieve a good effect of improving the water intake and drainage efficiency.

DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention but not to limit the scope of the present invention.

[0032] like Figure 1 As shown, the embodiment of the present invention discloses a washing machine with an auxiliary water inlet and outlet device. Figure 1 A connection diagram of the internal components of the washing machine is disclosed, and in order to distinguish the components, different washing machine components are filled in the drawings; and Figure 1 The arrows in FIG. 1 indicate the paths for filling water into the dual water paths in the washing tub 11 and draining water from the dual water paths in the washing tub 11; Figure 1 The washing machine of the present invention is specifically a drum washing machine, and the washing drum 11 includes an outer drum 111, an inner drum 112 and an inner drum shaft 113; a shock absorber 14 is connected to the bottom end of the outer drum 111; a door body 12 and a door body sealing gasket 13 are provided on one side of the drum washing machine.

[0033] Continue reading Figure 1 The washing machine with auxiliary water inlet and outlet device of the present invention further comprises a water inlet pipe 1 and a water outlet pipe 5. The water inlet pipe 1 is located above the washing tub 11 and communicates with the inside of the washing tub 11, specifically communicates with the outer tub 111 of the washing tub 11; the water outlet pipe 5 is located below the washing tub 11 and communicates with the bottom of the outer tub 111 of the washing tub 11;

[0034] The washing machine of the present invention further comprises a water inlet storage tank 2 and a water discharge storage tank 6. The water inlet storage tank 2 is installed inside the washing machine and is located above the washing drum 11. The water inlet storage tank 2 is connected to the washing drum 11 through the control of the first valve 4. During the water inlet period of the washing machine, the water inlet pipeline 1 and the water inlet storage tank 2 can simultaneously inject water into the double water paths in the washing drum 11; preferably, the water inlet pipeline 1 and the water inlet storage tank 2 are respectively injected with water at both ends of the top of the washing drum 11 in the horizontal direction.

[0035] The drainage water storage tank 6 is installed inside the washing machine and is located below the washing drum 11. The drainage water storage tank 6 is connected to the washing drum 11 through the control of the second valve 8. During the drainage of the washing machine, the washing drum 11 can simultaneously drain water to the drainage pipeline 5 and the drainage water storage tank 6. Preferably, the drainage pipeline 5 drains water from the middle position of the bottom of the washing drum 11, and the drainage water storage tank 6 drains water from the end of the bottom of the washing drum 11 away from the door body 12.

[0036] As a preferred embodiment of the present invention, the water inlet valve 3 of the present invention is used to control the tap water pipeline to inject water into the water inlet pipeline 1 or the water inlet storage tank 2; during the non-water filling period of the washing machine, the water inlet valve 3 controls the tap water pipeline to inject water into the water inlet storage tank 2; during the water filling period of the washing machine, the water inlet valve 3 controls the tap water pipeline to be connected with the water inlet pipeline 1, and the water inlet pipeline 1 injects water into the washing drum 11; at the same time, the water inlet storage tank 2 controls the injection of water into the washing drum 11 through the first valve 4.

[0037] It should be noted that the present invention selectively controls the connection between the tap water pipeline and the water inlet pipeline 1 and the water inlet storage tank 2 through the water inlet valve 3; for example, when the user starts washing, the program controls the washing machine to weigh, and during the weighing period, the program synchronously controls the water inlet valve 3 so that the tap water pipeline is connected to the water inlet storage tank 2 and water is injected; during the water injection period after the weighing is completed, the water inlet valve 3 controls the tap water pipeline to inject water into the water inlet pipeline 1, and at the same time the first valve 4 is opened, and the water in the water in the water inlet storage tank 2 and the water in the water inlet pipeline 1 are injected into the washing drum 11 at the same time, and the two water circuits are injected with water at the same time, which can save the injection time.

[0038] As a preferred embodiment of the present invention, the water inlet valve 3 of the present invention is used to control the tap water pipeline to inject water into the water inlet tank 2, that is, the water inlet valve 3 is used to control the opening and closing of the self-opening water pipeline and the water inlet tank 2; the water inlet tank 2 is connected to the washing drum 11 through the first valve 4; one end of the water inlet pipeline 1 is connected with the water inlet tank 2, and the other end thereof is connected with the inside of the washing drum 11; during the water inlet period of the washing machine, the washing machine controls the water inlet valve 3 to open to inject water into the water inlet tank 2, and the water inlet tank 2 injects water into the washing drum 11 through the first valve 4 and the water inlet pipeline 1.

[0039] As a preferred embodiment of the present invention, refer to Figure 1 The second valve 8 of the present invention is used to control the washing drum 11 to drain water into the drainage water storage tank 6; a drain port 7 and a drain valve are provided at the bottom of the washing drum 11, the drain port 7 is connected to the drainage pipeline 5, and the drain port 7 is controlled to open or close the drainage by the drain valve; and the drainage water storage tank 6 is connected to the drainage pipeline 5; during the drainage of the washing machine, the drain valve and the second valve 8 are opened, and the washing drum 11 can drain water simultaneously through the drain port 7 to the drainage pipeline 5 and through the second valve 8 to the drainage water storage tank 6.

[0040] Those skilled in the art can understand that the outlet of the drainage water storage tank 6 of the present invention is connected to the drainage pipe 5. When the water in the washing drum 11 is discharged simultaneously through the dual water channels, the water in the drainage water storage tank 6 can be discharged through the drainage pipe 5. Therefore, the present invention can achieve dual water channel drainage by only setting up one drainage pipe 5 and drainage water storage tank 6.

[0041] like Figure 1 As shown, a drainage pump 9 is provided on the drainage pipeline 5 of the present invention, and the drainage pipeline 5 is divided into two sections. The water inlet of the drainage pump 9 is connected with the drainage outlet of the washing drum 11 through the first section of the drainage pipeline 5, and the water outlet of the drainage pump 9 is connected with the second section of the drainage pipeline 5 for drainage; and the outlet of the drainage water storage tank 6 is connected with the water inlet of the drainage pump 9 through a pipeline.

[0042] The specific drainage process of the washing machine of the present invention, for example, when the program detects that the washing is finished and starts to drain, in addition to being discharged to the drainage pump 9 through the normal drainage port 7, the second valve 8 is controlled to be opened at the same time, and the water in the washing drum 11 is discharged to the drainage water storage tank 6 through the second valve 8. The double water circuit speeds up the drainage speed, and the water in the washing drum 11 can be discharged faster, shortening the washing time; when the program detects that the drainage pump 9 has no water to drain, the water in the drainage water storage tank 6 is discharged to the drainage pump 9 and discharged through the drainage pump 9.

[0043] It should be noted that the timing of determining when the water in the drainage water storage tank 6 is drained by the drainage pump 9 can be determined by first detecting the water level in the washing tub 11. When the water level in the washing tub 11 is zero or less than a preset value, the water in the drainage water storage tank 6 can be drained by the drainage pump 9. The second method is to detect the discharge flow of the drainage pump 9. When the discharge flow of the drainage pump 9 is zero or less than a preset value, the water in the drainage water storage tank 6 can be drained by the drainage pump 9. Those skilled in the art can specifically select a liquid level measuring device for detecting the water level in the washing tub 11 and a flow detection device for detecting the discharge flow of the drainage pump 9.

[0044] As a preferred embodiment of the present invention, the washing machine of the present invention is also provided with a circulation pipeline 10; one end of the circulation pipeline 10 is connected to the water outlet end of the drainage pump 9, and the other end thereof is connected to the interior of the washing drum 11, so that the water in the drainage water storage tank 6 can be discharged into the washing drum 11 through the drainage pump 9 and the circulation water pipeline 10 for recycling.

[0045] It should be noted that when the water discharged from the washing tub 11 to the drainage water storage tank 6 is relatively clean, the water in the drainage water storage tank 6 can be recycled; in a specific embodiment, a filtering device is provided in the circulation pipeline 10 to filter the water in the drainage water storage tank 6 for recycling. To determine whether to recycle the water in the drainage water storage tank 6, the turbidity of the water in the washing tub 11 or the drainage water storage tank 6 can be detected by a liquid turbidity detection device. When the turbidity measurement value is less than a preset value, it is determined that the water in the drainage water storage tank 6 can be recycled.

[0046] like Figure 1 As shown, the water inlet tank 2 and the drainage tank 6 of the present invention are both installed inside the washing machine; those skilled in the art can specifically set the installation positions of the water inlet tank 2 and the drainage tank 6. For example, the water inlet tank 2 and the drainage tank 6 of the present invention can also be installed outside the washing machine, that is, the washing machine only retains the water inlet valve 3 and the first valve 4, and realizes dual water-way water injection through the two valves; and the washing machine only retains the drainage valve and the second valve 8, and realizes dual water-way drainage through the two valves.

[0047] like Figure 2 As shown, the embodiment of the present invention also discloses a control method of the washing machine with the auxiliary water inlet and outlet device, comprising the following steps:

[0048] Step S1, detecting whether the washing machine is in the water intake period;

[0049] Step S2, if not, the washing machine controls the water to be injected into the water inlet storage tank 2;

[0050] Step S3, if yes, then water is simultaneously injected into the washing tub 11 through the water inlet pipe 1 and the water inlet storage tank 2;

[0051] Step S4, detecting whether the washing machine is in the drainage period;

[0052] Step S5, the washing tub 11 is drained simultaneously through the drainage pipeline 5 and the drainage water storage tank 6;

[0053] As a preferred implementation mode of the present invention, the control method further includes:

[0054] Step S6, detecting whether the drainage pipe 5 has completed drainage from the washing tub 11;

[0055] Step S7: If yes, the drainage water storage tank 6 drains water through the drainage pipeline 5.

[0056] As a preferred embodiment of the present invention, the "drainage water storage tank 6 drains water through the drainage pipeline 5" in step S7 specifically includes:

[0057] A drainage pump 9 is provided on the drainage pipeline 5 , and the water in the drainage water storage tank 6 is circulated and discharged into the washing tub 11 through the drainage pump 9 ; or the water in the drainage water storage tank 6 is discharged to the outside through the drainage pump 9 .

[0058] As a preferred embodiment of the present invention, the step S6 of "detecting whether the drainage pipeline 5 has completed drainage from the washing drum 11" specifically includes:

[0059] Detect whether the water level in the washing tub 11 is less than a preset value. If so, execute step S7; or detect whether the flow rate at the water outlet of the drainage pump 9 is less than a preset value. If so, execute step S7.

[0060] In summary, the present invention adopts a dual water inlet and dual water outlet method for the washing drum, which can reduce the water inlet and drainage time and shorten the washing time; and the structural design and logical control of the present invention do not require user processing, and can automatically determine the completion of the dual water inlet and dual water outlet control, saving user time and improving the user experience.

[0061] It should be noted that the above implementation mode is only used to illustrate the principles of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above method so that the present invention can be applied to more specific application scenarios.

[0062] For example, in a replaceable embodiment, the present invention can remove the water inlet storage tank 2 and the drainage water storage tank 6, and adopt two water inlet valves 3 and two drainage valves to realize the functions of dual waterway water inlet and dual waterway drainage; specifically, two water inlet pipes 1 can be respectively connected to the tap water pipe, and the two water inlet valves 3 can be used to control the on-off of the two water inlet pipes 1; and two drainage pipes 5 are used for drainage, and the on-off of the two drainage pipes 5 can be respectively controlled by two drainage valves, thereby realizing the effect of dual waterway water inlet and dual waterway drainage.

[0063] For example, in an alternative embodiment, the drain outlet 7 of the washing drum 11 of the present invention can be configured to be connected to the drain water tank 6, and the washing drum 11 is connected to the drain water tank 6 through the second valve 8, and the drain water tank 6 is connected to the drain pipe 5, so that during drainage of the washing machine of the present invention, the washing drum 11 simultaneously drains water into the drain water tank 6 through the drain outlet 7 and the second valve 8, and the drain water tank 6 is drained through the drain pipe 5 and the drain pump 9.

[0064] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
