[0051] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0052] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0053] According to an embodiment of the present application, an embodiment of a drainage box assembly is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0054] like Figure 1-7 As shown, the drainage box assembly is applied to a clothes processing device, wherein the clothes processing device is provided with a first tub and a second tub sequentially arranged up and down, and the drainage box assembly includes:

[0055] The box body 1 is provided with a first water inlet 11 for communicating with a first tub of the laundry treatment device, a second water inlet 12 for communicating with a second tub of the laundry treatment device, and a total water outlet 13 for discharging water in the box body 1; the first water inlet 11 is located higher than the second water inlet 12, and the second water inlet 12 is located higher than the total water outlet 13;

[0056] The box body 1 is formed with a first drainage cavity 5 and a second drainage cavity 6 that are connected to each other; the height of the connection position between the first drainage cavity 5 and the second drainage cavity 6 is higher than the height of the water outlet 13;

[0057] The first drainage cavity 5 is used to accommodate water entering from the first water inlet 11, and the second drainage cavity 6 is used to accommodate water entering from the second water inlet 12;

[0058] The main water outlet 13 is communicated with the first drainage cavity 5 , and the water in the second drainage cavity 6 enters the first drainage cavity 5 and is discharged from the main water outlet 13 .

[0059] In one embodiment, a laundry processing device refers to a device that washes or cares for laundry and requires water inlet and outlet. This embodiment does not specifically limit the structure, function, etc. of the laundry processing device. The laundry processing device includes a first tub and a second tub. Specifically, when the laundry processing device is a washing machine, the first tub is the first washing tub of the washing machine, and the second tub is the second washing tub of the washing machine. When the laundry processing device is a care machine, the first tub is the first care tub of the care machine, and the second tub is the second care tub of the care machine.

[0060] In one embodiment, when the first barrel is drained, the water in the first barrel enters the first water inlet 11 through a preset pipe, and the water in the first barrel flows into the first drainage chamber 5 after passing through the first water inlet 11, and then is discharged from the clothing processing device through the main water outlet 13; when the second barrel is drained, the water in the second barrel enters the second water inlet 12 through a preset pipe, and the water in the second barrel flows into the second drainage chamber 6 after passing through the second water inlet 12. When the water in the second drainage chamber 6 accumulates to a certain amount, it enters the first drainage chamber 5 through the connecting pipe between the second drainage chamber 6 and the first drainage chamber 5, and is finally discharged from the clothing processing device from the main water outlet 13.

[0061] As described above, the drainage box assembly includes a box body 1, wherein a first drainage cavity 5 and a second drainage cavity 6 are formed in the box body 1. Water in the second drainage cavity 6 must enter the first drainage cavity 5 before being discharged from the water outlet. This means that during normal drainage, water in the first drainage cavity 5 can be discharged directly from the water outlet without entering the second drainage cavity 6. This reduces the risk of water overflow and improves drainage quality.

[0062] In another embodiment of the present application, the drainage box assembly is further provided with an upper cover 14 cooperating with the box body 1 and a baffle 7 located inside the box body 1, and the baffle 7 is provided with a through hole connecting the first drainage chamber 5 and the second drainage chamber 6, or a gap is provided between the baffle and the upper cover to connect the first drainage chamber 5 and the second drainage chamber 6.

[0063] In one embodiment, a baffle 7 is used to separate the interior space of the box body 1 into a first drainage chamber 5 and a second drainage chamber 6, which are interconnected. Taking the example of a first and second tubs arranged one above the other, the baffle 7 is also vertically arranged, with its lower end connected to the inner bottom wall of the box body 1 and its upper end separated from the inner top wall of the box body 1 by a gap.

[0064] Through the above steps, a simple structure is used to form the first drainage cavity 5 and the second drainage cavity 6 that are interconnected, which helps to reduce the production cost and maintenance cost of the drainage box.

[0065] In another embodiment of the present application, the drainage box assembly further includes a liquid level monitoring device 2;

[0066] The liquid level monitoring device 2 includes a first probe and a second probe, the first probe is located in the first drainage chamber 5, and the second probe is located in the second drainage chamber 6; when the second probe detects water in the second drainage chamber 6 and the first probe detects water in the first drainage chamber 5, the first probe and the second probe output water signals to the outside.

[0067] In one embodiment, the liquid level monitoring device 2 is used to measure whether there is water in the second drainage cavity 6. In addition, the liquid level monitoring device 2 can be any type of sensor or other device with detection function, such as a liquid level sensor or a radar sensor, and this embodiment does not specifically limit this.

[0068] During drainage of the first bucket, under normal circumstances, water in the first drainage chamber 5 does not flow into the second drainage chamber 6 but is instead discharged directly from the water outlet 13. Therefore, if the drainage volume is excessive, once the liquid level monitoring device 2 detects the presence of water in the second drainage chamber 6, it generates a water presence signal. This allows the controller or user to detect water leakage based on the water presence signal and promptly address the problem. This prevents water from entering the second bucket during drainage, ensuring normal use of the second bucket and improving drainage quality.

[0069] In another embodiment of the present application, a drain valve 3 is installed on the box body 1. The drain valve 3 is arranged between the first water inlet 11 and the drain outlet of the first bucket, and is used to open or close the flow path between the drain outlet of the first bucket and the first water inlet 11;

[0070] The second water inlet 12 is connected to a drainage pump 4 , and the water inlet of the drainage pump 4 is connected to the drainage outlet of the second barrel, and the water outlet of the drainage pump is connected to the second water inlet 12 , for sending water in the second barrel into the second water inlet 12 .

[0071] In one embodiment, the drain valve 3 is installed on the upper cover 14 of the box body 1, and the first bucket is located above the upper cover 14, so the water in the first bucket can automatically flow into the box body 1 under the action of gravity. The second bucket is located at a lower height than the box body 1, so a drain pump 4 is set to drain the water for the second bucket.

[0072] The present application also provides a clothes processing device, such as Figure 8As shown, it includes a first barrel and a second barrel arranged in sequence up and down, the drain outlet of the first barrel is connected to the first water inlet of the drainage box assembly, and the drain outlet of the second barrel is connected to the second water inlet of the drainage box assembly.

[0073] The drainage box further includes a controller, which is electrically connected to the liquid level monitoring device 2 and is used to receive a water signal transmitted by the liquid level monitoring device 2;

[0074] The controller is configured to:

[0075] Acquiring the water presence signal and the status signal of the clothes processing device;

[0076] When the water signal and the status signal meet the water leakage condition, the drainage mode of the first bucket is changed to intermittent drainage.

[0077] In one embodiment, the electrical connection refers to the ability to exchange signals, data, etc. between the controller and the liquid level monitoring device 2 , which may be an optical fiber connection or an electric wire connection, and this embodiment does not specifically limit this.

[0078] In one embodiment, the status signal of the laundry processing device is used to represent the operating status of the laundry processing device, wherein the operating status refers to the working status of the first tub and the second tub, for example, the first tub is washing and the second tub is draining; for another example, the first tub and the second tub are both draining.

[0079] In one embodiment, the water-through condition is used to determine whether water-through occurs. This embodiment does not limit the specific content of the water-through condition. For ease of understanding, for example, in one application scenario, the water-through condition is when a water signal is obtained, whether the status signal indicates that the first bucket is in a draining state and the second bucket is not in a draining state. In other words, the water signal generated by the liquid level monitoring device 2 proves that water-through may occur. Whether water-through has occurred requires further judgment by the controller. The basis for judgment is whether the water signal and the status signal meet the water-through condition.

[0080] In one embodiment, intermittent drainage refers to periodic drainage, i.e., the water discharged from the first bucket enters the first drainage chamber 5 in a cyclical pattern of water entering, no water entering, and water entering again. It should be noted that intermittent drainage refers to the drainage method of the first bucket. Therefore, there are various methods for achieving intermittent drainage, such as providing a switch at the drainage point of the first bucket, which is periodically opened and closed, thereby achieving intermittent drainage of the first bucket. For another example, providing a switch at the first water inlet 11 of the box body 1, which is periodically opened and closed, thereby achieving intermittent drainage of the first bucket. This embodiment does not specifically limit this.

[0081] Through the above content, the drainage mode of the first bucket is changed to intermittent drainage, so that the water output of the box body 1 is greater than the water input, so that the water in the first drainage chamber 5 is not easy to enter the second drainage chamber 6, avoiding the water cross-flow phenomenon, and the water discharged from the first bucket is not easy to enter the second bucket, thereby ensuring the drainage quality.

[0082] In another embodiment of the present application, the drainage box further includes a drainage valve 3 , which is disposed at the first water inlet 11 and is used to open or close the first water inlet 11 ;

[0083] The controller is electrically connected to the drain valve 3, and the controller is configured as follows:

[0084] When the water signal and the status signal meet the water cross-contamination condition, the drain valve 3 is controlled to open intermittently, so that the drainage mode of the first barrel is intermittent drainage.

[0085] In one embodiment, a drainage valve 3 is provided on the box body 1 to control the rhythm of water entering the first water inlet 11, thereby achieving the purpose of intermittent drainage.

[0086] Through the above content, the water entering the first drainage chamber 5 is conveniently and accurately controlled to achieve intermittent water inflow, so that the water outflow of the box body 1 is greater than the water inflow, thereby ensuring the drainage quality.

[0087] In another embodiment of the present application, the controller is configured to:

[0088] In response to a status signal of the laundry processing apparatus, when the status signal indicates that the first tub is in a draining state and the second tub is not in a draining state, the liquid level monitoring device 2 is controlled to detect whether there is water in the second drainage chamber 6 .

[0089] In one embodiment, the liquid level monitoring device 2 does not detect whether there is water in the second drainage cavity 6 in real time, but performs the detection action after receiving the control instruction from the controller.

[0090] Through the above content, it is convenient to save the power of the liquid level monitoring device 2 and extend the service life of the liquid level monitoring device 2.

[0091] In another embodiment of the present application, the liquid level monitoring device 2 includes a first probe and a second probe, the first probe is located in the first drainage cavity 5, and the second probe is located in the second drainage cavity 6;

[0092] When the second probe detects water in the second drainage chamber 6 and the first probe detects water in the first drainage chamber 5, the electrical connection lines between the first and second probes and the controller are connected, so that the signals transmitted by the first and second probes form the water signal.

[0093] In one embodiment, devices for detecting whether there is water are provided in both the first drainage cavity 5 and the second drainage cavity 6, and the controller can only receive a water signal when both the first probe and the second probe detect water in the corresponding drainage cavity, thereby reducing the judgment logic of the controller.

[0094] Specifically, in one embodiment, the first probe and the second probe are both used to detect water level values, and the controller is configured to:

[0095] Acquire a water signal formed by signals transmitted by the first probe and the second probe, wherein the water signal includes a first water level value detected by the first probe and a second water level value detected by the second probe;

[0096] When the first water level value is less than a first threshold value and the second water level value is greater than a second threshold value, it is determined that no water leakage occurs, wherein the first threshold value is less than or equal to the second threshold value;

[0097] When the first water level value is greater than the first threshold value and the second water level value is less than the second threshold value, it is determined that water leakage occurs.

[0098] In another embodiment of the present application, the controller is configured to:

[0099] When the water signal is received, determining whether the status signal indicates that the first tub is in a draining state and the second tub is not in a draining state;

[0100] If yes, it is determined that the water flow condition is met;

[0101] Otherwise, it is determined that the water flow condition is not met.

[0102] or,

[0103] The controller is configured to:

[0104] When the water signal is received, determining whether the status signal indicates that the first tub is in a draining state and the second tub is not in a draining state;

[0105] If yes, determine whether the water level value of the second drainage chamber 6 in the water signal exceeds a preset water level threshold;

[0106] If the water level exceeds the threshold, it is determined that the water leakage condition is met;

[0107] If the first bucket is not in the draining state or the second bucket is in the draining state or the water level value does not exceed the water level threshold, it is determined that the water leakage condition is not met.

[0108] Through the above steps, the status signal of the clothing processing equipment can be used to complete the judgment of the water leakage condition, thereby accurately judging whether there is a water leakage phenomenon, which is conducive to accurately and quickly identifying the water leakage phenomenon, thereby facilitating timely treatment of the water leakage phenomenon, ensuring that sewage is not easy to enter the second bucket, and improving the drainage quality.

[0109] In another embodiment of the present application, the first barrel is located above the second barrel, and a drainage pump 4 is provided at the second water inlet 12 for introducing water in the second barrel into the second drainage cavity 6 .

[0110] In another embodiment of the present application, the baffle 7 is closer to the second water inlet 12 than to the first water inlet 11 .

[0111] In one embodiment, if Figure 5 As shown, the baffle 7 is arranged closer to the right side in the figure, so that the straight-line distance between the baffle 7 and the first water inlet 11 is greater than the straight-line distance between the baffle 7 and the second water inlet 12.

[0112] Through the above steps, the water outlet 13 is located in the first drainage chamber 5, and the baffle 7 is closer to the second water inlet 12, which helps to increase the capacity of the first drainage chamber 5, thereby accommodating more water and reducing the occurrence of water leakage.

[0113] For ease of understanding, Figure 2-7 As shown, the drainage box installed in the washing machine is used as an example for explanation.

[0114] The drainage box includes a controller and a box body 1. The box body 1 includes a removably connected upper cover 14 and a box body. The upper cover 14 has three openings: a first water inlet 11, which connects to the drain outlet of the washing machine's upper drum; a second opening for installing a drain valve 3; and a third opening that connects to the interior of the box body. The drain valve 3 is used to block the first water inlet 11 or to open the water flow path between the first water inlet 11 and the box body. The box body is provided with a second water inlet 12 and a water outlet 13. The second water inlet 12 connects to the drain outlet of the washing machine's lower drum, and a drain pump 4 is located between the lower drum drain and the second water inlet 12. When the lower drum needs to be drained, the drain pump 4 is activated, draining the water in the lower drum into the second water inlet 12, where it then enters the box body.

[0115] The baffle 7 is fixedly connected to the inside of the box body, which divides the inside of the box body into two interconnected chambers. Among them, the first drainage chamber 5 is directly connected to the first water inlet 11, and the water discharged from the upper bucket falls directly into the first drainage chamber 5; the second drainage chamber 6 is directly connected to the second water inlet 12, and the water discharged from the lower bucket falls directly into the second drainage chamber 6. Among them, the water outlet 13 is connected to the first drainage chamber 5, and the baffle 7 is vertically arranged and the upper end (with Figure 6 As an example, there is a gap between the second drainage chamber 6 and the top wall of the box body. When the water level in the second drainage chamber 6 is higher than the baffle 7, the water in the second drainage chamber 6 enters the first drainage chamber 5 through the gap and is then discharged from the water outlet 13.

[0116] A liquid level monitoring device 2 is provided inside the box body, and the liquid level monitoring device 2 includes two liquid level probes 8, wherein a liquid level probe 8 is provided in each of the first drainage chamber 5 and the second drainage chamber 6. The liquid level probe 8 is used to detect whether there is water in the corresponding chamber or to detect the water level in the corresponding chamber. When there is water in both the first drainage chamber 5 and the second drainage chamber 6 or the water levels are both greater than a preset threshold, the two liquid level probes 8 form a signal path with the controller, and the controller can obtain the detection signal (i.e., water signal) uploaded by the two liquid level probes 8. Specifically, a logic circuit can be provided to realize that when there is water in both the first drainage chamber 5 and the second drainage chamber 6 or the water levels are both greater than a preset threshold, the two liquid level probes 8 form a signal path with the controller, such as an AND gate circuit, which is not specifically limited in this embodiment.

[0117] The present application also provides a drainage method for the drainage box described above. Figure 8 Shown, including:

[0119] S102: When the water signal and the status signal meet the water leakage condition, the drainage mode of the first bucket is changed to intermittent drainage.

[0120] Specifically, when the water signal and the status signal meet the water leakage condition, the drain valve is controlled to open intermittently, so that the drainage mode of the first barrel is intermittent drainage.

[0121] Specifically, determining whether the status signal indicates that the first tub is in a draining state and the second tub is not in a draining state;

[0122] If yes, it is determined that the water flow condition is met;

[0123] Otherwise, it is determined that the water flow condition is not met.

[0126] If the water level exceeds the threshold, it is determined that the water leakage condition is met;

[0127] If the first bucket is not in the draining state or the second bucket is in the draining state or the water level value does not exceed the water level threshold, it is determined that the water leakage condition is not met.
