It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0050] In the subsequent description, suffixes such as "module," "component," or "unit" used to represent components are used solely to facilitate the description of the present invention and do not have specific meanings. Therefore, "module," "component," or "unit" may be used interchangeably. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the various embodiments or technical features described below may be arbitrarily combined to form new embodiments.

[0051] Example 1

[0052] The present invention provides a method for controlling drainage of a washing machine. Figure 1 As shown, the following steps are included:

[0053] S11, obtaining a drainage instruction;

[0054] S12, turning on the drain pump and configuring the drain pump to perform a first draining action for N seconds; wherein, after performing the first draining action for N seconds, a continuous draining water flow is formed at the outlet of the drain pipe outside the washing machine box and fills the drain waterway;

[0055] S13. The drainage pump stops working to drain water through the siphon effect.

[0056] In this embodiment, specifically, Figures 4 to 6As shown, the washing machine is equipped with a drain pump 11 and an upper drain pipe 12 within the casing, and an external drain pipe 13 outside the casing. The routing and height of the upper drain pipe 12 and external drain pipe 13 form a drainage waterway structure that meets siphonic conditions. In the initial drainage phase, the power generated by the drain pump 11 performs a first drainage operation, forming a continuous drainage flow at the outlet of the external drain pipe 13 that fills the drainage waterway. At this point, the siphonic drainage requirements are met, and the drain pump 11 is stopped, allowing drainage to proceed under the siphon effect. This shortens the operating time of the drain pump 11 and reduces the noise impact caused by the operation of the drain pump 11.

[0057] In one embodiment, if Figure 2 As shown, the method further includes the steps of: S141, obtaining the water level value in the washing machine drum;

[0058] S142, comparing the current water level value with the first drainage threshold;

[0059] S143. If the current water level is less than or equal to the first drainage threshold, the drain pump is turned on and the second drainage action is executed until the drainage program ends. Specifically, the real-time water level in the washing machine drum is obtained through the water level detector installed in the washing machine, and the current water level is compared with the first drainage threshold through the computer program on the control panel in the washing machine. As the siphon drainage time increases, the water level in the drum decreases. When the water level in the drum decreases to less than or equal to the first drainage threshold, that is, the water level in the drum is low at this time, which is insufficient to allow the water in the drum to be continuously discharged. This may easily cause bubbles to be mixed in the water in the drainage waterway formed jointly inside and outside the washing machine casing, causing the siphon effect to fail. In order to ensure continuous drainage, the drain pump is turned on at this time, and the remaining water in the drum is discharged under the power provided by the drain pump.

[0060] Furthermore, the execution power of the first drainage action is greater than or equal to the execution power of the second drainage action. Specifically, the execution power of the second drainage action is equivalent to the execution power of the drainage action of a conventional washing machine. When the diameter of the drainage pipe inside the washing machine case is smaller than the diameter of the drainage pipe outside the case, in order to quickly meet the siphon effect, the execution power of the first drainage action is configured to be greater than the execution power of the second drainage action, so that the water in the washing machine drum forms a rapid flow to quickly fill the entire drainage waterway. When the diameter of the drainage pipe inside the washing machine case is the same as the diameter of the drainage pipe outside the case, the execution power of the first drainage action is configured to be equal to the execution power of the second drainage action, and the execution power of the second drainage action can meet the conditions for quickly forming a siphon effect without increasing the execution power of the drainage pump 11.

[0061] Specifically, the duration (N seconds) of the first drainage action performed by the drain pump 11 can be determined through pre-production testing. The drum, drain pump 11, and internal and external drainage pipes of the same specifications are configured to determine the duration (N seconds) of the first drainage action for different operating modes of the washing machine. The corresponding duration (N seconds) for each operating mode is stored in the storage module of the washing machine.

[0062] Furthermore, the step of determining the duration of N seconds includes the following steps:

[0063] Get the outlet water level value of the drainage pipe outside the box;

[0064] When the outlet water level equals the first preset water level, the siphon pipe is deemed full of water. At this point, the drain pump 11's operating duration, t1, equals the first drainage duration, N seconds. Specifically, a water level detector is provided within the outlet 131 of the external drain pipe 13 to detect the outlet water level. The washing machine is equipped with a timer to detect the duration of the outlet water level equaling the first preset water level. Furthermore, to ensure a stable siphon effect, operating duration t1 is delayed by a number of seconds, representing a duration of N seconds. For example, a 2-second delay of t1 results in a total duration of N seconds.

[0065] Example 2

[0066] The present invention provides a drainage control device, comprising:

[0067] an acquiring unit configured to acquire a drainage instruction;

[0068] The processing unit is configured to control the drain pump to stop working after executing the first drainage action for N seconds, so as to drain water through the siphon effect. Specifically, after the user selects the washing mode through the interface, when the operation reaches the drainage program, the acquisition unit obtains the drainage instruction. The processing unit configures the drain pump to work according to the drainage instruction. After the drain pump executes the first drainage action for N seconds, a continuous drainage water flow is formed at the outlet of the drain pipe 13 outside the box that fills the drainage waterway. At this time, the siphon drainage requirement is met, and the drain pump 11 is stopped to drain water under the siphon effect, shortening the working time of the drain pump 11.

[0069] Further, including:

[0070] Water level detector, used to obtain the water level value in the washing machine drum;

[0071] a matching unit configured to determine whether a current water level value is less than or equal to a first drainage threshold;

[0072] The processing unit is further configured to, when the current water level is less than or equal to the first drainage threshold, control the drain pump to perform a second drainage action until the drainage process ends. Specifically, as the siphon drainage time increases, the water level detector detects a decrease in the water level in the drum. When the matching unit determines that the water level in the drum has dropped to less than or equal to the first drainage threshold, i.e., the water level in the drum is too low to allow for continuous drainage of the water, this can easily lead to bubbles in the water in the drainage channel formed between the inside and outside of the washing machine casing, rendering the siphon effect ineffective. To ensure continuous drainage, the processing unit controls the drain pump to activate, and the remaining water in the drum is drained under the power provided by the drain pump.

[0073] In one embodiment, the water level detector can be disposed within the outer cylinder 20, between the outer cylinder 20 and the inner cylinder and below the outer cylinder 20, or within a gas pipe connected to the inner cylinder. When the water level detector is disposed within a hydraulic air pipe connected to the inner cylinder, the water level within the inner cylinder is determined by measuring the air pressure within the hydraulic air pipe. The higher the water level, the greater the water pressure, and thus the higher the air pressure within the hydraulic air pipe.

[0074] In one embodiment, it includes:

[0075] The matching unit is further configured to determine whether the current water level value is greater than or equal to a second drainage threshold;

[0076] The processing unit is also configured to control the opening and closing of the drainage pump to realize a drainage mode combining drainage by the drainage pump and drainage by the siphon effect when the current water level value is greater than or equal to the second drainage threshold. Specifically, the water level in the drum is different in different operating modes of the washing machine. When in a certain operating mode, the matching unit judges that the water level value in the washing machine drum is less than the second drainage threshold, then the siphon drainage effect is not good at this time, and it may even only be able to maintain a short period of siphon drainage and still need to rely on the drainage pump 11, which causes the drainage pump 11 to start and close multiple times in a short period of time, and the noise reduction effect is not obvious, and starting and closing multiple times in a short period of time is not conducive to the long-term use of the drainage pump 11. Therefore, the matching unit is designed to judge that the current water level value is greater than or equal to the second drainage threshold, and the processing unit controls the formation of a drainage mode combining drainage by the drainage pump and drainage by the siphon effect.

[0077] Example 3

[0078] The present invention provides a method for draining water from a washing machine. Figure 3 As shown, the following steps are included:

[0079] S21, obtaining the water level value in the washing machine drum;

[0080] S22, comparing the current water level value with the second drainage threshold;

[0081] S23. If the current water level is greater than or equal to the second drainage threshold, the washing machine drainage control method described above is executed. Specifically, because the water level in the washing machine drum varies in different operating modes, if the water level in a particular operating mode is less than the second drainage threshold, siphon drainage may be ineffective, or even only maintain short-term siphon drainage before requiring reliance on the drain pump 11. This causes the drain pump 11 to cycle multiple times within a short period of time, resulting in insignificant noise reduction. Furthermore, this cycle of cycling multiple times within a short period of time is detrimental to the long-term use of the drain pump 11.

[0082] Example 4

[0083] The present invention provides a washing machine, such as Figures 4 to 7 As shown, a washing machine 100 is included. The washing machine 100 includes the drainage control device and the drainage assembly 10 as described above. The drainage assembly 10 includes:

[0084] The drainage pump 11 is provided in the drainage waterway in the washing machine body to generate water flow power;

[0085] The upper drain pipe 12 is provided in the washing machine casing, and its water outlet end extends upward and out of the casing;

[0086] The water inlet of the external drainage pipe 13 is connected to the water outlet of the upper drainage pipe 12, and the water outlet extends downward so that the upper drainage pipe 12 is connected to the external drainage pipe 13 to form a siphon pipe;

[0087] During drainage, the drainage control device acts to fill the drainage channel in the washing machine box and the drainage pipe 13 outside the box to form siphon drainage.

[0088] Specifically, during drainage, water flows upward in the upper drain pipe 12, flows into the external drain pipe 13, and then flows downward along the external drain pipe 13. The upper drain pipe 12, the external drain pipe 13 cooperate with the washing machine drum to meet the external conditions of the siphon condition. When the drain pump 11 is turned on, the washing machine drum is drained so that the upper drain pipe 12 and the external drain pipe 13 are filled with water, the siphon drainage is activated, the drain pump 11 is turned off, and the operating time of the drain pump 11 is shortened, thereby achieving a noise reduction effect.

[0089] In one embodiment, the external drainage pipe 13 is curved and includes a vertically arranged first pipe 132 and a horizontally arranged second pipe 133. The height of the first pipe 132 and its assembly with the upper drainage pipe 12 are designed to meet the requirements of the siphon effect. The provision of the second pipe 133 facilitates the assembly of the external drainage pipe 13 with external pipelines.

[0090] In one embodiment, a first transmission pipe 14 is further included, which is connected to the upper drain pipe 12 and is respectively connected to the drain pump 11. Specifically, the first transmission pipe 14 and the upper drain pipe 12 are provided in the washing machine casing. On the one hand, due to space limitations within the casing, the first transmission pipe 14 and the upper drain pipe 12 cooperate to facilitate the layout of the drainage piping within the casing; on the other hand, it facilitates the assembly of the drain pump 11 with the drainage waterway within the casing. That is, the drain pump 11 is connected to the first transmission pipe 14 and the upper drain pipe 12, respectively, thus completing the assembly of the drain pump 11.

[0091] Furthermore, it also includes a second transmission pipe 15 and a filter structure 16; the second transmission pipe 15 is connected to the drum of the washing machine; the first transmission pipe 14 and the second transmission pipe 15 are connected through the filter structure 16. Specifically, the second transmission pipe 15 is provided so that the filter structure 16 can be set on the drainage waterway in the washing machine body to filter out stains and lint in the water discharged from the drum to avoid affecting the subsequent siphon drainage. In addition, the washing machine is also provided with a circulating water pipe to form a circulating waterway in the washing machine 100 to save water. The circulating water pipe is connected to the drain pump 11. After the water from the washing machine drum is discharged into the second transmission pipe 15, it is filtered by the filter structure 16 and enters the first transmission pipe 14; the water in the first transmission pipe 14 can enter the upper drain pipe 12 and / or the circulating water pipe through the drain pump 11. The water entering the upper drain pipe 12 is subsequently discharged outside the box, and the water entering the circulating water pipe is used to form the circulating water for the washing machine.

[0092] Furthermore, the second transmission pipe 15 is provided at the bottom of the outer tube 20 to communicate with the drain port provided at the bottom of the outer tube 20 .

[0093] Furthermore, the first transmission pipe 14 has a curved structure to shorten the distance between the filter structure 16 and the drainage pump 11 , effectively utilizing the space inside the box, and facilitating the miniaturization design of the drainage assembly 10 .

[0094] Furthermore, the second transmission pipe 15 is a curved structure, which extends downward along the cylinder drainage pipe and then extends toward the rear of the cylinder, so that the upper drainage pipe 12 can be arranged behind the cylinder to avoid the height design of the upper drainage pipe 12 being limited by the cylinder.

[0095] In one embodiment, a timer is further included to obtain the execution time of the drain pump 11 so as to cooperate with the drain pump 11 to perform the first drainage action for N seconds.
