[0032] In the embodiment of the present invention, the second delivery box 2 is flushed by using the water flow flowing through the first delivery box 1 and the flushing pipeline 3, thereby avoiding residual detergent in the second delivery box 2 and reducing the waste of detergent.

[0033] The clothes processing device includes the following:

[0034] The first type of clothing processing device: The clothing processing device is a drum washing machine, which includes an outer shell 14, an outer drum, an inner drum rotatably arranged in the outer drum, and a dispensing assembly, the dispensing assembly includes a first dispensing box 1 and a second dispensing box 2; the inner drum is a hole-free inner drum, and the inner drum is used as a water storage drum when washing clothes independently, and the first dispensing box 1 and the second dispensing box 2 dispense detergent into the inner drum; or, the outer drum is a water storage drum, and the first dispensing box 1 and the second dispensing box 2 dispense detergent into the outer drum.

[0035] like Figure 1 As shown, the second type of clothing processing device: the clothing processing device is a double-drum washing machine, which includes an outer shell 14, a first outer drum and a second outer drum arranged in the outer shell 14, a first inner drum arranged in the first outer drum, a second inner drum arranged in the second outer drum, and a dispensing component, the dispensing component includes a first dispensing box 1 and a second dispensing box 2; the first inner drum and the second inner drum are inner drums without holes, and the inner drums are used as water drums when washing clothes independently, and the first dispensing box 1 and the second dispensing box 2 dispense detergent into the first inner drum and the second inner drum; or, the first outer drum and the second outer drum are water drums, and the first dispensing box 1 and the second dispensing box 2 dispense detergent into the first outer drum and the second outer drum, wherein the outer shell 14 can be a first outer shell 14 and a second outer shell 14 independent of each other, the first outer drum and the first inner drum are arranged in the first outer shell 14, and the second outer drum and the second inner drum are arranged in the second outer shell 14.

[0036] In the second type of clothing processing device, preferably, the first delivery box 1 and the second delivery box 2 are arranged on the top of the shell 14 and above all the cylinders, the liquid outlet of the second delivery box 2 is connected with the liquid inlet of the first delivery box 1, and the liquid outlet of the first delivery box 1 is respectively connected with the upper water holding cylinder 15 and the lower water holding cylinder 16; the first delivery box 1 is connected with the external water inlet pipeline; it should be noted that the first delivery box 1 is provided with a water inlet channel connected with the flushing pipeline 3, a water inlet channel for flushing the detergent in the first delivery box 1 and for feeding water into the water holding cylinder, and each water inlet channel is connected with the external water inlet pipeline; the delivery device includes not only the first delivery box 1 and the second delivery box 2, but also other delivery boxes, and the type of detergent delivered by each delivery box may be the same or different.

[0037] The first delivery box 1 comprises a box body and a box cover, wherein the box cover comprises an upper cover and a lower cover which are buckled with each other, and the upper cover and the lower cover are buckled with each other, so that a plurality of independent water inlet channels are formed inside the box cover.

[0038] A liquid storage box for storing detergent is provided in the second delivery box 2. The liquid storage box can be pushed and pulled in the second delivery box 2. When the liquid storage box is pushed and pulled, liquid will leak. If the leaked liquid is not treated for a long time, it will become dry, hard, moldy, etc. Therefore, the flushing pipeline 3 is used to flush the residual detergent in the second delivery box 2.

[0039] When dispensing, the detergent in the second dispensing box 2 is sucked into the first dispensing box 1 and mixed with the detergent in the first dispensing box 1. The mixed liquid is flushed into the upper water cylinder 15 and / or the lower water cylinder 16 by the water flow entering from the first dispensing box 1.

[0040] During flushing, the water flowing out from the water inlet channel of the first delivery box 1 enters the second delivery box 2 through the flushing pipeline 3 to flush the residual detergent in the second delivery box 2. The mixed liquid obtained after flushing the second delivery box 2 enters the upper water cylinder 15 and / or the lower water cylinder 16 through the first delivery box 1.

[0041] like Figure 2 As shown, in the embodiment of the present invention, the first delivery box 1 and the second delivery box 2 are arranged side by side on the left and right, the water outlet of the water inlet channel is arranged on the first delivery box 1 and faces the water inlet of the second delivery box 2, and the flushing pipeline 3 is arranged between the first delivery box 1 and the second delivery box 2 and extends horizontally between the first delivery box 1 and the second delivery box 2.

[0042] In the embodiment of the present invention, specifically, the first delivery box 1 and the second delivery box 2 are arranged at the top of the housing 14 and above all the tubes, the first delivery box 1 is arranged on the left side of the housing 14, and the second delivery box 2 is arranged on the right side of the housing 14, the first delivery box 1 and the second delivery box 2 have the same shape and specification, and the first delivery box 1 and the second delivery box 2 are arranged side by side. The first delivery box 1 and the second delivery box 2 are arranged in this way to facilitate manual delivery of detergent and make full use of the space of the housing 14;

[0043] A water inlet channel is provided on the top of the first delivery box 1. Since the water outlet of the water inlet channel is arranged face to face with the water inlet of the second delivery box 2, the flushing pipeline 3 is provided between the first delivery box 1 and the second delivery box 2, which can shorten the length of the flushing pipeline 3, reduce the space occupied, and reduce the flushing time, thereby improving the flushing efficiency. In order to speed up the flushing water flow from the first delivery box 1 to the second delivery box 2 through the flushing pipeline 3 and flush the second delivery box 2, a suction pump can be provided on the flushing pipeline 3; and the flushing pipeline 3 extends horizontally between the first delivery box 1 and the second delivery box 2 to avoid bending of the flushing pipeline 3, reduce obstruction to the water flow, and speed up the flow of water.

[0044] like Figure 2 As shown, in an embodiment of the present invention, a recovery pipeline for recovering the mixed liquid obtained by flushing the second delivery box 2 is provided between the first delivery box 1 and the second delivery box 2, the liquid inlet of the recovery pipeline is connected with the liquid outlet of the second delivery box 2, and the liquid outlet is connected with the liquid inlet of the first delivery box 1, and the first delivery box 1 has a liquid outlet.

[0045] In the embodiment of the present invention, the water flow enters the second delivery box 2 from the flushing pipeline 3 to flush the second delivery box 2, and a mixed liquid of water and detergent is obtained after flushing. In order to fully utilize the mixed liquid into the water storage cylinder, a recovery pipeline is provided between the first delivery box 1 and the second delivery box 2. The recovery pipeline delivers the mixed liquid from the second delivery box 2 to the first delivery box 1, and the mixed liquid then enters the water storage cylinder from the liquid outlet of the first delivery box 1;

[0046] Specifically, a first delivery box 1 is provided with a first delivery cavity and a second delivery cavity, a first recovery pipeline 4 corresponding to the first delivery cavity and a second recovery pipeline 5 corresponding to the second delivery cavity are provided between the first delivery box 1 and the second delivery box 2, the first delivery cavity has a first liquid outlet 17 provided at the bottom of the first delivery box 1, and the second delivery cavity has a second liquid outlet 18 provided at the side of the first delivery box 1. The first liquid outlet 17 of the first delivery cavity is communicated with the upper water cylinder 15, and the second liquid outlet 18 of the second delivery cavity is communicated with the lower water cylinder 16;

[0047] During recycling, the first recycling pipeline 4 delivers the mixed liquid into the first delivery chamber in the first delivery box 1, and the mixed liquid then enters the upper water storage cylinder 15 from the first liquid outlet 17 of the first delivery chamber, and the second recycling pipeline 5 delivers the mixed liquid into the second delivery chamber in the first delivery box 1, and the mixed liquid then enters the lower water storage cylinder 16 from the second liquid outlet 18 of the second delivery chamber;

[0048] For example, when the water level in the upper water cylinder 15 reaches the set water level, if the first recovery pipe 4 continues to send the mixed liquid into the first delivery chamber and the upper water cylinder 15, the water level in the upper water cylinder 15 will exceed the set water level, resulting in the upper water cylinder 15 being unable to wash normally. At this time, the flushing time of the second delivery box 2 has not reached the set time, and the second delivery box 2 is not flushed sufficiently. Therefore, before the water level in the lower water cylinder 16 reaches the set water level, the second recovery pipe 5 can send the mixed liquid in the second delivery box 2 into the second delivery chamber and the lower water cylinder 16, so that the flushing time of the second delivery box 2 can reach the set time, so that the residual detergent in the second delivery box 2 can be fully cleaned.

[0049] like Figure 2 As shown, further, the first recovery pipeline 4 and the second recovery pipeline 5 extend horizontally between the first delivery box 1 and the second delivery box 2, the first recovery pipeline 4, the second recovery pipeline 5 and the flushing pipeline 3 are arranged at the same height, and the first recovery pipeline 4 and the second recovery pipeline 5 are respectively arranged on the front and rear sides of the flushing pipeline 3.

[0050] The first recovery pipeline 4 and the second recovery pipeline 5 extend horizontally, which can shorten the length of the pipeline, reduce the space occupied, avoid bending of the recovery pipeline, reduce obstruction to the water flow, speed up the flow of water, and improve the recovery efficiency; in order to speed up the mixed liquid from the second delivery box 2 into the first delivery box 1, a suction pump can be set on the first recovery pipeline 4 and the second recovery pipeline 5.

[0051] In an embodiment of the present invention, a liquid storage box for storing detergent is provided in the second delivery box 2, a delivery pipeline is provided between the first delivery box 1 and the second delivery box 2, the liquid inlet of the delivery pipeline is connected to the liquid outlet of the liquid storage box, and the liquid outlet is connected to the liquid inlet of the first delivery box 1.

[0052] In the embodiment of the present invention, a liquid storage box for storing detergent is provided in the second delivery box 2. When delivering detergent, the delivery pipeline delivers the detergent in the liquid storage box into the first delivery box 1, and the detergent is flushed into the water storage cylinder by the water flow in the first delivery box 1;

[0053] like Figure 2 As shown, specifically, a first liquid storage box 6 and a second liquid storage box 7 are arranged side by side on the left and right inside the second delivery box 2, a first delivery pipeline 8 corresponding to the first liquid storage box 6, and a second delivery pipeline 9 corresponding to the second liquid storage box 7 are provided between the first delivery box 1 and the second delivery box 2, and the liquid outlet of the first delivery pipeline 8 and the liquid outlet of the second delivery pipeline 9 are both connected to the first delivery cavity and the second delivery cavity.

[0054] Two liquid storage boxes are provided in the second delivery box 2. Different detergents or the same detergents can be stored in the two liquid storage boxes. The two liquid storage boxes are arranged side by side in the second delivery box 2, so that the space in the second delivery box 2 can be fully utilized.

[0055] The first delivery chamber is connected to a first water inlet channel, and the second delivery chamber is connected to a second water inlet channel. When water is delivered, the first water inlet channel introduces water into the first delivery chamber to enter the upper water cylinder 15, and the second water inlet channel introduces water into the second delivery chamber to enter the lower water cylinder 16.

[0056] During delivery, the first delivery pipeline 8 delivers the detergent in the first liquid storage box 6 into the first delivery chamber and the second delivery chamber respectively, and the second delivery pipeline 9 delivers the detergent in the second liquid storage box 7 into the first delivery chamber and the second delivery chamber respectively. The detergent in the first liquid storage box 6 and the detergent in the second liquid storage box 7 are mixed in the first delivery chamber and in the second delivery chamber. The water flow provided by the first water inlet flow channel flushes the mixed detergent in the first delivery chamber into the upper water holding cylinder 15 through the first liquid outlet 17 of the first delivery chamber, and the water flow provided by the second water inlet flow channel flushes the mixed detergent in the second delivery chamber into the lower water holding cylinder 16 through the second liquid outlet 18 of the second delivery chamber.

[0057] like Figure 2As shown, further, the first delivery pipeline 8 and the second delivery pipeline 9 extend horizontally between the first delivery box 1 and the second delivery box 2, the first delivery pipeline 8, the second delivery pipeline 9 and the flushing pipeline 3 are arranged at the same height, the first delivery pipeline 8 and the second delivery pipeline 9 are arranged front to back and are arranged between the flushing pipeline 3 and the second recovery pipeline 5.

[0058] The first delivery pipeline 8 and the second delivery pipeline 9 extend horizontally, which can shorten the length of the pipeline, reduce the space occupied, avoid bending of the delivery pipeline, reduce obstruction to the detergent, speed up the flow of the detergent, and improve the recovery efficiency; in order to speed up the entry of the detergent from the liquid storage box into the delivery cavity, a suction pump can be set on the first delivery pipeline 8 and the second delivery pipeline 9.

[0059] like Figure 3 and Figure 4 As shown, further, a detection component is provided in the second delivery box 2, and the detection component includes a position detection device 19 for detecting whether the liquid storage box is pushed into the second delivery box 2 and a liquid level detection device 20 for detecting whether the liquid level in the second delivery box 2 reaches a set liquid level;

[0060] The in-place detection device 19 detects whether the user has pushed or pulled the liquid storage box. If the liquid storage box has been pushed or pulled, the in-place detection device 19 will memorize it and rinse the second delivery box 2 when it is not the last rinse.

[0061] The probe of the in-place detection device 19 is embedded in the second delivery box 2 from the top of the second delivery box 2 and suspended in the second delivery box 2. When the liquid storage box is pushed into the second delivery box 2, the probe can detect the second delivery box 2; the in-place detection device 19 can be in various forms such as a micro switch and a reed switch.

[0062] The probe of the liquid level detection device 20 is embedded in the second delivery box 2 from the top of the second delivery box 2 and is suspended in the second delivery box 2. The liquid level detection device 20 can be in various forms such as a float switch.

[0063] If the liquid in the second delivery box 2 exceeds the set water level when flushing the second delivery box 2, the liquid level will submerge the steel needle. If the second delivery box 2 continues to be flushed, the flushing water will overflow, which will damage the electrical components near the second delivery box 2 and cause safety hazards.

[0064] In an embodiment of the present invention, a third liquid storage box 10 and a fourth liquid storage box 11 are arranged side by side on the left and right inside the first delivery box 1, a third delivery pipeline is arranged on the third liquid storage box 10, and a fourth delivery pipeline is arranged on the fourth liquid storage box 11. The liquid outlet of the third delivery pipeline and the liquid outlet of the fourth delivery pipeline are both connected to the first delivery cavity and the second delivery cavity.

[0065] In the embodiment of the present invention, two liquid storage boxes are arranged in the first delivery box 1, and different detergents or the same detergents can be stored in the two liquid storage boxes. The two liquid storage boxes are arranged side by side in the first delivery box 1, so that the space in the first delivery box 1 can be fully utilized;

[0066] During delivery, the third delivery pipeline delivers the detergent in the third liquid storage box 10 into the first delivery chamber and the second delivery chamber respectively, and the fourth delivery pipeline delivers the detergent in the fourth liquid storage box 11 into the first delivery chamber and the second delivery chamber respectively. The detergent in the third liquid storage box 10 and the detergent in the fourth liquid storage box 11 are mixed in the first delivery chamber and in the second delivery chamber. The water flow provided by the first water inlet flow channel flushes the mixed detergent in the first delivery chamber into the upper water storage cylinder 15 through the first liquid outlet 17 of the first delivery chamber, and the water flow provided by the second water inlet flow channel flushes the mixed detergent in the second delivery chamber into the lower water storage cylinder 16 through the second liquid outlet 18 of the second delivery chamber. Suction pumps are provided on both the third delivery pipeline and the fourth delivery pipeline.

[0067] like Figure 1 As shown, the first liquid outlet 17 of the first delivery chamber is connected to the upper water storage cylinder 15 via the fifth delivery pipeline 12 , and the second liquid outlet 18 of the second delivery chamber is connected to the lower water storage cylinder 16 via the sixth delivery pipeline 13 .

[0068] When the first delivery box 1 and the second delivery box 2 are delivered at the same time, the detergents in all the liquid storage boxes are sucked into the first delivery chamber and the second delivery chamber, all the detergents are mixed in the first delivery chamber and mixed in the second delivery chamber, and the water flow flushes the mixed detergents in the first delivery chamber into the upper water cylinder 15 and the mixed detergents in the second delivery chamber into the lower water cylinder 16.

[0069] In the embodiment of the present invention, when the time for the incoming water flow to flush the second delivery box 2 reaches the set flushing time or the number of flushing times reaches the set flushing times, it is determined that there is no detergent residue in the second delivery box 2.

[0070] In the embodiment of the present invention, whether there is detergent residue in the second dispensing box 2 is determined by whether the flushing time reaches the set flushing time or whether the flushing times reach the set flushing times;

[0071] When the flushing time reaches the set flushing time or the number of flushing times reaches the set number of times, it is considered that there is no detergent residue in the second delivery box 2; when the flushing time does not reach the set flushing time or the number of flushing times does not reach the set number of flushing times, it is considered that there is detergent residue in the second delivery box 2, and water needs to continue to flow into the second delivery box 2.

[0072] After each flushing of the second delivery box 2, there will be residual flushing water in the second delivery box 2 due to negative pressure. At this time, a liquid pump is used to extract the residual water into the first delivery box 1, and then the water flow can be flushed into the water storage cylinder.

[0073] If it is detected that the liquid storage box in the second delivery box 2 has been pulled out, there is detergent residue in the second delivery box 2. The second delivery box 2 is rinsed before the last rinse, and the rinse water and the residual detergent are flushed into the water drum at the same time. The reason for not rinsing in the last rinse is that the detergent will be flushed into the water drum, resulting in an unclean final rinse.

[0074] Furthermore, the clothing treatment device further comprises a water drum, and when the first delivery box 1 is supplied with water into the water drum, the inflowing water flow rinses the second delivery box 2, and if the water level in the water drum reaches the set water level and the rinsing time does not reach the set rinsing time, the inflowing water flow rinses the second delivery box 2 again when waiting for the next time water is supplied into the water drum;

[0075] When the first delivery box 1 is feeding water into the water cylinder, the water flow can enter the second delivery box 2 from the first delivery box 1 through the flushing pipeline 3 to flush the second delivery box 2, so that the water flow can be fed into the water cylinder and flush the second delivery box 2 when the water inlet waterway is fed with water;

[0076] If the flushing time cannot reach the set flushing time when the water drum is filled with water for the first time, resulting in detergent residue in the second washing box, you can wait until the water drum is filled with water for the second time to continue flushing the second delivery box 2, so that the sum of the two flushing times can reach the set flushing time.

[0077] For example, when water is introduced into the water tank during the washing stage, since a large amount of washing water is already stored in the water tank, the water level in the water tank has not reached the set water level. When water is introduced into the water tank, it only takes a short time to irrigate the water tank, and the water level in the water tank can reach the set water level. At this time, the flushing time for the second delivery box 2 has not reached the set flushing time. Therefore, you can wait until water is introduced into the water tank during the rinsing stage to continue flushing the second delivery box 2.

[0078] Furthermore, if the water level in the water drum reaches the set water level, but the flushing time has not reached the set flushing time, the incoming water flow continues to flush the second delivery box 2, and the water level in the water drum is higher than the set water level, the drain port of the water drum is opened, part of the water in the water drum is discharged, and the incoming water flow continues to flush the second delivery box 2; if the water level in the water drum is higher than the set water level, the washing machine cannot operate normally. Therefore, at this time, it is necessary to stop flushing the second delivery box 2, and the washing machine alarm prompts that the clothes cannot be washed, and prompts the user to remove part of the water in the water drum, so that the water level in the water drum is lower than the set water level, and the incoming water flow continues to flush the second delivery box 2. After the flushing time reaches the set flushing time, the washing machine is restarted to execute the washing program.

[0079] The washing machine is provided with a timing sensor, which is used to detect the flushing time of the second delivery box 2. The washing machine is provided with a controller, and the timing sensor, the liquid level detection device 20 and the arrival detection device 19 are connected to the controller. The timing sensor transmits the detected flushing time to the controller.

[0080] Furthermore, when waiting for the next time water to flow into the water storage cylinder and the incoming water flow to flush the second delivery box 2, if the liquid level in the second delivery box 2 exceeds the set liquid level, the liquid in the second delivery box 2 is first sucked into the first delivery box 1, and then the second delivery box 2 is flushed by the incoming water flow.

[0081] When flushing the second delivery box 2, if the liquid level detection device 20 detects that the liquid level in the second delivery box 2 exceeds the set liquid level, the liquid in the second delivery box 2 is sucked into the first delivery box 1 to prevent the liquid in the second delivery box 2 from overflowing due to excessive liquid, thereby damaging the electrical components near the second delivery box 2 and causing safety hazards.

[0082] In an embodiment of the present invention, the clothing processing device has an upper water cylinder 15 and a lower water cylinder 16, and the incoming water flow after flushing the second delivery box 2 enters the upper water cylinder 15 and the lower water cylinder 16, or the incoming water flow after flushing the second delivery box 2 selectively enters the upper water cylinder 15 and the lower water cylinder 16.

[0083] Furthermore, the upper water cylinder 15 executes the water inlet procedure before the lower water cylinder 16, and the water flow after flushing the second delivery box 2 first enters the upper water cylinder 15. If, when the lower water cylinder 16 executes the water inlet procedure, the water level in the upper water cylinder 15 does not reach the set water level, and the flushing time does not reach the set flushing time, then the water flow after flushing the second delivery box 2 enters the upper water cylinder 15 and enters the lower water cylinder 16 at the same time.

[0084] Furthermore, the upper water cylinder 15 executes the water inlet procedure before the lower water cylinder 16. The water flow after flushing the second delivery box 2 first enters the upper water cylinder 15. When the water level in the upper water cylinder 15 reaches the set water level, the flushing time has not reached the set flushing time, and it is determined whether the lower water cylinder 16 executes the water inlet procedure. If it is executed, the water flow after flushing the second delivery box 2 enters the lower water cylinder 16 while waiting for the lower water cylinder 16 to fill with water.
