[0061] With the improvement of people's living standards, clothing processing devices have long become one of the indispensable household appliances in daily life. Twin-tub washing machines can wash different types of clothes separately, which can avoid cross-contamination.

[0062] On the one hand, users generally reserve a floor drain outlet for the clothing processing device, and the drain pipes of the two clothing processing barrels in the twin-barrel washing machine need to be connected to the drainage box and integrated into a main drain pipe for drainage. On the other hand, due to various external factors, such as excessive water pressure in a clothing processing barrel or blockage of the drainage box, the liquid in one clothing processing barrel may flow into the other clothing processing barrel in the drainage box, resulting in cross-contamination of the two clothing processing barrels, affecting the user experience.

[0063] Example 1

[0064] Based on this, Figures 1-6 As shown, the drainage box 15 according to an embodiment of the present invention includes:

[0065] Box body 1, box body 1 includes a top wall, a bottom wall and side walls;

[0066] The top wall, the bottom wall and the side walls form a cavity;

[0067] A partition structure is provided in the box body 1, which divides the cavity into a first drainage cavity 101, a second drainage cavity 102 and a main drainage cavity;

[0068] The second drainage cavity 102 and the main drainage cavity extend from the bottom wall to the top wall, and the second drainage cavity 102 is arranged around the periphery of the main drainage cavity or on one side of the main drainage cavity;

[0069] The first drainage cavity 101 extends from the top wall toward the lower wall and is inserted into the main drainage cavity;

[0070] A first communication port is provided between the upper portion of the second drainage chamber 102 and the upper portion of the main drainage chamber, and a second communication port is provided between the lower portion of the first drainage chamber 101 and the lower portion of the main drainage chamber, and the position of the first communication port is higher than that of the second communication port;

[0071] The top wall is provided with a first water inlet 2 communicating with the first drainage cavity 101, the side wall is provided with a second water inlet 3 communicating with the second drainage cavity 102, and the bottom wall is provided with a main drainage port 4 communicating with the main drainage cavity;

[0072] The second water inlet 3 is lower than the first communicating port, and the main drain port 4 is lower than the second communicating port.

[0073] Specifically, the box body 1 can be a rectangular shell 7, and the outer shell of the box body 1 is sealed to prevent liquid leakage. The internal space of the box body 1 can be divided into a first drainage chamber 101 and a second drainage chamber 102 by a partition plate or a structural design on the shell 7 of the box body 1, wherein the first drainage chamber 101 is a chamber extending in the longitudinal direction, and the top of the first drainage chamber 101 is connected to the first water inlet pipe, and the bottom is connected to the drain pipe, so that the liquid discharged into the box body 1 by the first water inlet pipe can directly enter the drain pipe for drainage, and the second drainage chamber 102 is located on the side of the first drainage chamber 101, or it can be arranged around the first drainage chamber 101, the bottom end of the side of the second drainage chamber 102 is connected to the second water inlet pipe, and the top end of the side is connected to the first drainage chamber 101, so that after the liquid in the second water inlet pipe enters the box body 1, it can start to accumulate from the bottom of the second drainage chamber 102 until it rises to the top of the second drainage chamber 102, and then enter the first drainage chamber 101, and then enter the drain pipe from the first drainage chamber 101 for drainage.

[0074] Among them, such as Figure 4 and attached Figure 5As shown, the direction of the arrow is the direction of the liquid discharged from the second water inlet 3 in the box body 1. Specifically, the first drainage chamber 101 and the second drainage chamber 102 divide the interior of the box body 1 into two parts, thereby separating the liquid entering the box body 1 from the first water inlet 2 and the second water inlet 3. Due to the gravity of the water itself, the liquid in the second drainage chamber 102 overflows into the first drainage chamber 101, and will flow downward along the first drainage chamber 101 to the main drainage port 4, instead of flowing upward to the first drainage port, causing the liquid in the second drainage port to enter the first drainage port; the liquid in the first drainage port is directly discharged into the interior of the first drainage chamber 101, and will flow directly downward from the interior of the first drainage chamber 101 to the main drainage port 4, instead of flowing upward in the first drainage chamber 101 to the second drainage chamber 102, causing the liquid in the first drainage pipe to enter the second drainage port, thereby realizing liquid separation and avoiding cross-flow, which causes mutual contamination between the barrels and affects the customer experience.

[0075] According to the drainage box 15 of the embodiment of the present invention, the first drainage chamber 101 and the second drainage chamber 102 are connected to the first water inlet 2 and the second water inlet 3 respectively. During the drainage process, the liquid in the first drainage port enters the first drainage chamber 101 and is directly discharged through the main drainage port 4, while the liquid in the second water inlet 3 first enters the bottom of the second drainage chamber 102, and will first accumulate in the second drainage chamber 102, and then overflow from the second drainage chamber 102 into the first drainage chamber 101, and finally be discharged from the main drainage port 4. The liquid discharged from the first water inlet 2 and the second water inlet 3 are effectively separated by the first drainage chamber 101 and the second drainage chamber 102, thereby avoiding the cross-flow of the liquid entering the drainage box 15 from the first water inlet 2 and / or the second water inlet 3, which affects the customer's usage experience.

[0076] In some embodiments, the separator structure includes a first separator and a second separator, wherein

[0077] The first partition extends from the bottom wall toward the top wall, dividing the lower portion of the cavity into a second drainage cavity 102 and a main drainage cavity. A first communication gap is formed between the top end of the partition and the top wall, and the first communication gap constitutes a first communication port.

[0078] The second partition extends from the top wall to the bottom wall and is inserted into the main drainage cavity. The second partition is annular and forms a cylindrical cavity. The cylindrical cavity constitutes the first drainage cavity 101.

[0079] A second communication gap is formed between the lower end of the cylindrical cavity formed by the second partition and the bottom wall, and the second communication gap forms a second communication port.

[0080] Specifically, the partition has water-proof properties, and the interior of the box body 1 is divided into a first drainage chamber 101, a second drainage chamber 102 and a total drainage chamber through the partition, thereby separating the liquid entering the box body 1 through the first drainage port and the second drainage port to avoid liquid leakage.

[0081] In some embodiments, the first partition is in the shape of a plate or a ring;

[0082] When the first partition is plate-shaped, the second drainage cavity 102 is located on one side of the main drainage cavity;

[0083] When the first partition is annular, the second drainage cavity 102 is disposed around the outer periphery of the main drainage cavity.

[0084] Specifically, the first partition can be a plate-shaped, dividing the total drainage chamber into two parts. The first partition can also be an annular retaining rib 5 protruding upward from the lower wall inside the box body 1. The partition and the box body 1 adopt an integrated structure to ensure the sealing performance of the partition itself. Moreover, the partition is annular, and the first drainage chamber 101 can be set as a cylinder, while the second drainage chamber 102 is a ring arranged around the first drainage chamber 101. Compared with simply dividing the box body 1 into left and right sides, this design of the partition can increase the length of the connection between the first drainage chamber 101 and the second drainage chamber 102, and increase the connection area. When the liquid in the second drainage chamber 102 is full and overflows upward, it can enter the first drainage chamber 101 more quickly and conveniently.

[0085] In some embodiments, the first partition is integrally formed with the box body 1 or inserted through the first water inlet 2; and / or

[0086] The second partition is integrally formed with the box body 1 or inserted through the main drain port 4 .

[0087] Specifically, the first partition plate and the second partition plate can be made into an integral part with the box body 1 to ensure the sealing performance, and can also be assembled and assembled later, which is more convenient for adapting to different types of pipelines.

[0088] In some embodiments, the first partition extends into the bottom of the second partition.

[0089] Specifically, the first partition can extend into the bottom of the second partition, and the liquid in the first drain port enters the first partition. After the liquid in the first partition is discharged, it is directly discharged to the main drain port 4, further reducing the possibility of the liquid in the first partition splashing into the second drain chamber 102 and then flowing back from the second drain chamber 102 to the second drain port, causing liquid leakage.

[0090] In some embodiments, the flow area of ​​the first water inlet 2 is smaller than the flow area of ​​the first drainage chamber 101, the flow area of ​​the second water inlet 3 is smaller than the flow area of ​​the second drainage chamber 102, the flow area of ​​the second drainage chamber 102 is smaller than the flow area of ​​the first connecting port, and the flow area of ​​the first drainage chamber 101 and the flow area of ​​the first connecting port are both smaller than the flow area of ​​the total drainage port 4.

[0091] Specifically, the flow areas of the first water inlet 2 and the total drain outlet 4 can be the inner diameters of the first water inlet 2 and the total drain outlet 4 respectively. The inner diameter of the first water inlet 2 is smaller than the inner diameter of the first drain cavity 101, which can make the drainage efficiency of the first drain cavity 101 greater than the water inlet efficiency of the first water inlet 2, and can make the liquid discharged into the box body 1 by the first water inlet 2 smoothly enter the total drain outlet 4 through the first drain cavity 101, and the flow area of ​​the second drain outlet can be the inner diameter of the second water inlet 3. The flow area of ​​the first drain cavity 101 is is the cross-sectional area of ​​the first drainage chamber 101, the flow area of ​​the second drainage chamber 102 is the cross-sectional area of ​​the second drainage chamber 102, the flow area of ​​the first connecting port is the drainage cross-sectional area between the first drainage chamber 101 and the second drainage chamber 102, the flow area of ​​the first drainage chamber 101 and the flow area of ​​the first connecting port are both smaller than the flow area of ​​the total drainage port 4, which can enable the liquid discharged into the box body 1 from the second water inlet 3 and the first drainage port to be discharged smoothly through the total drainage port 4, avoiding the accumulation of a large amount of liquid in the box body 1, resulting in liquid channeling.

[0092] In some embodiments, the box body 1 includes: an upper cover 6 and a shell 7;

[0093] The upper cover 6 is covered on the top of the shell 7 and is detachably connected to the shell 7 . The first water inlet 2 is arranged on the upper cover 6 , and the second water inlet 3 is arranged at the bottom of the side wall of the shell 7 .

[0094] Specifically, the shell 7 can be a rectangular shell 7 with an opening at the top. The upper cover 6 is adapted to the opening and can be snapped onto the shell 7. The upper cover 6 is detachably connected to the shell 7. The shell box body 1 can be assembled or disassembled for maintenance by disassembling the upper cover 6. When there is a blockage in the box body 1, it can be easily unblocked and repaired.

[0095] Example 2

[0096] As attached Figure 7 As shown, the embodiment of the present application further provides a clothes processing device, comprising: an upper tub 8, a lower tub 9 and the aforementioned drainage box 15;

[0097] One of the upper tub 8 and the lower tub 9 is connected to a first drainage system 10 , and the other is connected to a second drainage system 16 ;

[0098] The first drainage system 10 and the second drainage system 16 are respectively connected to the first water inlet 2 and the second water inlet 3 of the drainage box 15 , and the main drainage port 4 of the drainage box 15 is connected to the third drainage system 17 .

[0099] Specifically, the upper barrel 8 and the lower barrel 9 can be two clothing processing barrels of the clothing processing device, respectively. The upper barrel 8 and the lower barrel 9 are arranged in the whole machine frame 18, wherein the upper barrel 8 can be connected to the first water inlet through the first drainage system 10, and the lower barrel 9 is connected to the second water inlet through the second drainage system 16, or the upper barrel 8 can be connected to the second water inlet 3 through the second drainage system 16, and the lower barrel 9 is connected to the first water inlet 2 through the first drainage system 10. After the upper barrel 8 and the lower barrel 9 are connected to the drainage box 15, the drainage box 15 is connected to the third drainage system 17 through the main drainage port 4, and the liquid in the upper barrel 8 and / or the lower barrel 9 is discharged through the third drainage system 17.

[0100] Among them, the drainage box 15 is located in the middle area of ​​the upper barrel 8 and the lower barrel 9, and the lower barrel 9 is connected to the first water inlet 2 through the first drainage system 10. When the upper barrel 8 is connected to the second water inlet 3 through the second drainage system 16, the water in the lower barrel 9 is pumped into the drainage box 15 by the water pump, and the liquid in the first drainage chamber 101 in the drainage box 15 overflows and flows to the second drainage chamber 102, and then enters the second water inlet 3. Due to the gravity of the water, it will not immediately enter the upper barrel 8, so that the drainage box 15 has a better anti-flow effect.

[0101] In some embodiments, the first drainage system 10 includes: a control valve 11, a drainage channel 13 and a tee pipe 12;

[0102] The downward end of the three-way pipe 12 is the first water inlet pipe 2, and the three-way pipe 12 is integrally formed with the upper cover 6 of the drainage box. The other two ends of the three-way pipe 12 are respectively connected to the control valve 11 and the drainage channel 13, and the drainage channel 13 is connected to the upper barrel 8 or the lower barrel 9.

[0103] Specifically, the tee pipe 12 is located above the drainage box body 1, and a branch of the tee pipe 12 pointing vertically downward is the first water inlet pipe 2, and this branch of the tee pipe 12 is integrally formed with the upper cover 6. When the upper cover 6 is buckled on the box body 1, the connection operation between the first drainage system 10 and the drainage box is completed, which can facilitate assembly and improve production efficiency.

[0104] The other two branches of the tee pipe 12 are connected to the control valve 11 and the drainage channel 13 respectively. The drainage channel 13 can discharge the liquid in the upper barrel 8 or the lower barrel 9 to the tee pipe 12. If it is the connected upper barrel 8, the liquid can be automatically discharged under the action of gravity. If it is the connected lower barrel 9, a water pump can be added to drive the liquid to move. The control valve 11 can switch the first water inlet pipe 2 or adjust the liquid flow therein.

[0105] In some embodiments, the invention further comprises: a water level sensor, the water level sensor being disposed inside the first drainage cavity 101; and

[0106] The control module controls the drainage speed of the first drainage system 10 and / or the third drainage system 17 based on the water level signal of the water level sensor.

[0107] Specifically, the control module can be integrated into the original controller of the clothing processing device. The control valve 11 can be a flow proportional valve having an electrically adjustable opening mechanism to adjust the flow rate. The water level sensor can detect the liquid height in the first drainage chamber 101. When liquid accumulates in the first drainage chamber 101 and rises to the top, it indicates that the liquid in the first drainage chamber 101 is about to overflow into the second drainage chamber 102. At this time, the control module adjusts the control valve 11 to change the instantaneous flow of the first drainage system 10 through the control valve 11, or changes the flow of the first drainage system 10 over a period of time by opening and closing the control valve 11 to slow down the drainage speed of the first drainage system 10. Alternatively, a water pump can be added to the third drainage system 17 to increase the drainage speed of the third drainage system 17 through the water pump in the third drainage system 17 to prevent the liquid in the first drainage chamber 101 from overflowing into the second drainage chamber 102 and then flowing into the second water inlet pipe 3, causing crossflow.

[0108] In some embodiments, controlling the drainage speed of the first drainage system 10 includes:

[0109] Control the flow area of ​​the control valve 11, or control the opening and closing rhythm of the control valve 11.

[0110] Specifically, the volume of liquid flowing through the control valve 11 within a period of time can be changed by changing the opening and closing size of the control valve 11, changing the flow area of ​​the liquid in the control valve 11, or opening and closing the control valve 11 continuously. By reducing the drainage speed of the first drainage system 10, a large amount of water accumulation in the drainage box can be avoided, which may lead to crossflow.

[0111] In some embodiments, a water pump is provided in the third drainage system 17 to control the drainage speed of the third drainage system 17, including:

[0112] Control the pumping speed of the water pump.

[0113] Specifically, the water pumping speed can be changed by changing the power of the water pump, thereby speeding up the drainage of the third drainage system 17, and a large amount of water is accumulated in the drainage box, resulting in crossflow.

[0114] Example 3

[0115] The embodiment of the present application further provides a control method for a clothes processing device, comprising: if the liquid in the first drainage chamber 101 is about to overflow, slowing down the drainage speed of the first drainage system 10 and / or speeding up the drainage speed of the third drainage system 17 .

[0116] Specifically, if the liquid in the first drainage chamber 101 overflows, it will enter the second drainage chamber 102 and then flow to the second water inlet 3, causing crossflow. Therefore, before the liquid in the first drainage chamber 101 overflows, the clothing processing device can be controlled by the control module, and the drainage speed of the first drainage system 10 can be adjusted by the control valve 11 to slow down the drainage speed, that is, the amount of liquid entering the drainage box per unit time is reduced, thereby avoiding continued water accumulation in the drainage box and preventing liquid from entering the second drainage chamber 102. In addition, the water pump in the third drainage system 17 can be turned on simultaneously or separately to increase the drainage speed of the third drainage system 17 through the water pump, or to increase the power of the water pump to further increase the drainage speed of the third drainage system 17 to avoid the liquid being higher than the first drainage chamber 101 and causing crossflow.

[0117] In some embodiments, if the water in the first drainage cavity 101 is about to overflow, the process includes:

[0118] Monitor the water level in the first drainage chamber 101. If the water level in the first drainage chamber 101 reaches the top of the first drainage chamber 101, it is determined that the liquid in the first drainage chamber 101 is about to overflow.
