Description

[Technical Field]

[0001] The present invention relates to the technical field of household electrical appliances, and more particularly to a loading device, a clothes processing device and a control method thereof. [Background technology]

[0002] A washing machine performs washing, rinsing, and spin-drying to remove dirt from clothes by utilizing the interaction between detergent and water. A dryer is another typical laundry treatment device, and is a household appliance used to dry wet clothes. In recent years, household appliances that combine the functions of a washing machine and a dryer have become widely used.

[0003] As people's quality of life improves, hygiene awareness is also gradually increasing. Especially when it comes to washing clothes at home, more and more people are washing their clothes separately. If existing washing machines are used to perform multiple washes, it is difficult to meet the needs for washing time. If two or more washing machines are purchased to perform separate washes at the same time, not only will energy and water resources be greatly wasted, but the space occupied will be large and unsuitable for home use. Therefore, the use of multi-drum washing machines can meet the above needs and solve the problems of wasting energy, water, and space.

[0004] Existing drum-type washing machines have an upper water holding drum, a lower water holding drum, and a dosing assembly for dosing detergent into the water holding drums. The dosing assembly includes a first dosing case and a second dosing case, both of which have liquid storage cases that can be pushed and pulled. When dosing, the detergent in the second dosing case is sucked into the first dosing case by a suction pump, and the water flow in the first dosing case causes the detergent to flow into the upper water holding drum and / or the lower water holding drum. However, because the second dosing case is not connected to a water injection line, the detergent remaining in the second dosing case cannot be washed into the wash drum and fully utilized by pushing and pulling the liquid storage case, resulting in wasted detergent.

[0005] In view of the above, the present invention is proposed. Summary of the Invention [Problem to be solved by the invention]

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the existing technology and provide a detergent dispenser and a laundry treatment device that washes a second dispenser using a water flow flowing through a first dispenser and a cleaning pipe, thereby achieving the purpose of preventing detergent from remaining in the second dispenser and reducing detergent waste. [Means for solving the problem]

[0007] In order to solve the above technical problems, the basic idea of the technical proposal adopted in the present invention will be described below.

[0008] The present invention provides a dosing device including a first dosing case having a water injection flow path therein and a second dosing case, and further including a cleaning pipeline, the water inlet of the cleaning pipeline being connected to the water outlet of the water injection flow path, and the water outlet of the cleaning pipeline being connected to the water inlet of the second dosing case.

[0009] Furthermore, the first input case and the second input case are installed side by side, the outlet of the water injection flow path is provided in the first input case and is installed facing the surface of the water inlet of the second input case, and the cleaning pipeline is provided between the first input case and the second input case and extends horizontally between the first input case and the second input case.

[0010] Furthermore, a recovery pipeline is provided between the first input case and the second input case to recover the mixed liquid obtained by cleaning the second input case, the liquid inlet of the recovery pipeline being connected to the liquid outlet of the second input case, the liquid outlet of the recovery pipeline being connected to the liquid inlet of the first input case, and the first input case having a liquid outlet.

[0011] Furthermore, a first input lumen and a second input lumen are provided within the first input case, and a first return line corresponding to the first input lumen and a second return line corresponding to the second input lumen are provided between the first input case and the second input case, and the first input lumen has a first liquid outlet provided at the bottom of the first input case, and the second input lumen has a second liquid outlet provided at the side of the first input case.

[0012] Furthermore, the first recovery pipeline and the second recovery pipeline extend horizontally between the first input case and the second input case, the first recovery pipeline, the second recovery pipeline and the cleaning pipeline are installed at the same height, and the first recovery pipeline and the second recovery pipeline are respectively provided on both the front and rear sides of the cleaning pipeline.

[0013] Furthermore, a liquid storage case for storing detergent is provided within the second input case, and an input conduit is provided between the first input case and the second input case, with the liquid inlet of the input conduit communicating with the liquid outlet of the liquid storage case and the liquid outlet of the input conduit communicating with the liquid inlet of the first input case.

[0014] Furthermore, a first liquid storage case and a second liquid storage case are installed in parallel on the left and right sides within the second input case, and a first input pipeline corresponding to the first liquid storage case and a second input pipeline corresponding to the second liquid storage case are installed between the first input case and the second input case, and the liquid outlet of the first input pipeline and the liquid outlet of the second input pipeline are both connected to the first input lumen and the second input lumen.

[0015] Furthermore, the first input pipeline and the second input pipeline extend horizontally between the first input case and the second input case, the first input pipeline, the second input pipeline and the cleaning pipeline are installed at the same height, the first input pipeline and the second input pipeline are arranged side by side in the front and back, and are provided between the cleaning pipeline and the second recovery pipeline.

[0016] Furthermore, a third liquid storage case and a fourth liquid storage case are provided inside the first input case, arranged in parallel on the left and right, and a third input pipeline is provided in the third liquid storage case, and a fourth input pipeline is provided in the fourth liquid storage case, and the liquid outlet of the third input pipeline and the liquid outlet of the fourth input pipeline are both connected to the first input lumen and the second input lumen.

[0017] The present invention further provides a clothing treatment device comprising a housing, and an upper water retention drum and a lower water retention drum arranged within the housing, and further comprising an input device provided by the above-mentioned technical solution, wherein the input device is arranged above the upper water retention drum, the liquid outlet of the second input case is connected to the liquid inlet of the first input case, and the liquid outlet of the first input case is connected to the upper water retention drum and the lower water retention drum respectively.

[0018] The present invention further provides a control method for a clothing treatment device, which adopts the clothing treatment device provided by the above-mentioned technical solution, in which a first input case is connected to a second input case through a cleaning pipe, the clothing treatment device has a cleaning program, and when the cleaning program is executed, the cleaning pipe is opened and the second input case is cleaned by the water flow flowing through the first input case and the cleaning pipe.

[0019] Furthermore, when the time it takes for the water flow to wash the second dispenser case reaches the set wash time, or the number of washes reaches the set number of washes, it is determined that there is no detergent remaining in the second dispenser case.

[0020] Furthermore, the laundry treatment device further includes a water holding drum, and the water pouring stream washes the second input case at the same time that the first input case pours water into the water holding drum, and if the washing time has not reached the set washing time when the water level in the water holding drum reaches the set water level, the water pouring stream waits for the second input case to wash again the next time water is poured into the water holding drum.

[0021] Furthermore, if the washing time has not yet reached the set washing time when the water level in the water drum reaches the set water level, the water injection stream continues to wash the second input case, and even if the water level in the water drum becomes higher than the set water level, the water drain port of the water drum is opened to discharge some of the water in the water drum, so that the water injection stream continues to wash the second input case.

[0022] Furthermore, when the next water injection into the water holding drum is on standby and the water injection flow is used to clean the second injection case again, if the liquid level in the second injection case exceeds the set liquid level, the liquid in the second injection case is first sucked into the first injection case, and the second injection case is again cleaned using the water injection flow.

[0023] Furthermore, a liquid storage case for storing detergent is provided within the second input case so that it can be pulled out. When it is detected that the liquid storage case within the second input case has been pulled out, the second input case is cleaned before the final rinse water injection, since there is residual detergent in the second input case.

[0024] Furthermore, the clothing treatment device has an upper water retention drum and a lower water retention drum, and the water flow after washing the second input case enters the upper water retention drum and the lower water retention drum, or the water flow after washing the second input case alternatively enters the upper water retention drum and the lower water retention drum.

[0025] Furthermore, the upper water holding drum executes the water injection program prior to the lower water holding drum, and the water flow after cleaning the second input case first enters the upper water holding drum. However, when the lower water holding drum executes the water injection program, if the water level in the upper water holding drum has not reached the set water level and the cleaning time has not reached the set cleaning time, the water flow after cleaning the second input case will enter both the upper water holding drum and the lower water holding drum.

[0026] Furthermore, the upper water holding drum executes the water injection program prior to the lower water holding drum, and the water injection stream after washing the second input case first enters the upper water holding drum. However, if the water level in the upper water holding drum reaches the set water level but the wash time has not yet reached the set wash time, it is determined whether the lower water holding drum is executing the water injection program. If it is, when filling the lower water holding drum with water, the water injection stream after washing the second input case waits for it to enter the lower water holding drum. [Effects of the Invention]

[0027] By using the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0028] The second input case is cleaned using the water flow that flows through the first input case and the cleaning pipe, preventing detergent from remaining in the second input case and reducing detergent waste.

[0037] In an embodiment of the present invention, the second input case 2 is cleaned by the water flow flowing through the first input case 1 and the cleaning pipe 3, preventing detergent from remaining in the second input case 2 and reducing detergent waste.

[0038] The above-mentioned clothing processing devices include the following types:

[0040] As shown in FIG. 1, the second type of clothing treatment device is a two-drum washing machine, which includes a housing 14, a first outer drum and a second outer drum provided in the housing 14, a first inner drum provided in the first outer drum, a second inner drum provided in the second outer drum, and an input assembly, and the input assembly includes a first input case 1 and a second input case 2, and the first inner drum and the second inner drum are inner drums without holes, and the inner drum is used as a water holding drum when washing clothing alone; The first input case 1 and the second input case 2 input detergent into the first inner drum and the second inner drum, or the first outer drum and the second outer drum are water holding drums, and the first input case 1 and the second input case 2 input detergent into the first outer drum and the second outer drum, and the housing 14 may be a first housing 14 and a second housing 14 independent of each other, and the first outer drum and the first inner drum are provided in the first housing 14, and the second outer drum and the second inner drum are provided in the second housing 14.

[0041] In the second type of laundry treatment device, the first input case 1 and the second input case 2 are preferably provided on the upper part of the housing 14 and located above all the drums, the liquid outlet of the second input case 2 is connected to the liquid inlet of the first input case 1, the liquid outlets of the first input case 1 are connected to the upper water holding drum 15 and the lower water holding drum 16, respectively, and the first input case 1 is connected to an external water injection pipe. In addition, the first input case 1 is provided with a water injection channel connected to the washing pipe 3 and a water injection channel for washing the detergent in the first input case 1 and injecting water into the water holding drum, and both water injection channels are connected to an external water injection pipe. The input device includes not only the first input case 1 and the second input case 2 but also other input cases, and the types of detergent dispensed by each input case may be the same or different.

[0042] The first input case 1 includes a case body and a case lid, and the case lid includes an upper lid and a lower lid that engage with each other, and the upper lid engages with the lower lid, thereby forming several independent water injection channels inside the case lid.

[0043] A liquid storage case for storing detergent is provided within the second input case 2, and the liquid storage case is provided so as to be pushable and removable within the second input case 2. When the liquid storage case is removed, liquid may leak, and if the liquid leakage is not treated for a long period of time, it may dry out and harden, or mold may grow. Therefore, the remaining detergent in the second input case 2 is washed using the cleaning pipe 3.

[0044] During addition, the detergent in the second addition case 2 is sucked into the first addition case 1 and mixed with the detergent in the first addition case 1, and the mixed liquid is forced into the upper water holding drum 15 and / or the lower water holding drum 16 by the water flow entering from the first addition case 1.

[0045] During cleaning, the water flow flowing out from the water injection flow path of the first input case 1 passes through the cleaning pipe 3 and enters the second input case 2 to wash away any detergent remaining in the second input case 2, and the mixed liquid obtained after cleaning the second input case 2 passes through the first input case 1 and enters the upper water holding drum 15 and / or the lower water holding drum 16.

[0046] As shown in Figure 2, in this embodiment of the present invention, the first input case 1 and the second input case 2 are installed side by side, the water outlet of the water injection flow path is provided in the first input case 1 and is installed facing the water inlet of the second input case 2, and the cleaning pipeline 3 is provided between the first input case 1 and the second input case 2 and extends horizontally between the first input case 1 and the second input case 2.

[0047] In this embodiment of the present invention, specifically, the first dispenser case 1 and the second dispenser case 2 are arranged on the top of the housing 14 and are located above all the drums, the first dispenser case 1 is arranged on the left side of the housing 14, and the second dispenser case 2 is arranged on the right side of the housing 14, the first dispenser case 1 and the second dispenser case 2 have the same shape and specifications, and are installed side by side, which makes it convenient to manually dispense detergent and makes full use of the space in the housing 14.

[0048] A water injection channel is provided on the top of the first input case 1, and the water outlet of the water injection channel is installed opposite the water inlet of the second input case 2. The cleaning pipe 3 is provided between the first input case 1 and the second input case 2, thereby shortening the length of the cleaning pipe 3, reducing the space occupied, and shortening the cleaning time and improving the cleaning efficiency. A suction pump can be provided in the cleaning pipe 3 to speed up the flow of cleaning water from the first input case 1 through the cleaning pipe 3 into the second input case 2 to clean the second input case 2. In addition, the cleaning pipe 3 extends horizontally between the first input case 1 and the second input case 2, which avoids bending the cleaning pipe 3, reduces obstacles to the water flow, and speeds up the water flow.

[0049] As shown in Figure 2, in an embodiment of the present invention, a recovery pipeline is provided between the first input case 1 and the second input case 2 to recover the mixed liquid obtained by cleaning the second input case 2, and the liquid inlet of the recovery pipeline is connected to the liquid outlet of the second input case 2, and the liquid outlet of the recovery pipeline is connected to the liquid inlet of the first input case 1, and the first input case 1 has a liquid outlet.

[0050] In an embodiment of the present invention, the water flow enters the second input case 2 from the cleaning pipe to clean the second input case 2, and a mixed liquid of water and detergent is obtained after cleaning. In order to fully utilize the mixed liquid in the water holding drum, a recovery pipe is provided between the first input case 1 and the second input case 2, and the recovery pipe injects the mixed liquid from the second input case 2 into the first input case 1, and the mixed liquid further enters the water holding drum through the liquid outlet of the first input case 1.

[0051] Specifically, a first input lumen and a second input lumen are provided within first input case 1, a first return line 4 corresponding to the first input lumen and a second return line 5 corresponding to the second input lumen are provided between first input case 1 and second input case 2, the first input lumen has a first liquid outlet 17 provided at the bottom of first input case 1, and the second input lumen has a second liquid outlet 18 provided at the side of first input case 1. First liquid outlet 17 of the first input lumen communicates with upper water holding drum 15, and second liquid outlet 18 of the second input lumen communicates with lower water holding drum 16.

[0052] During recovery, the first recovery line 4 delivers the mixed liquid to a first input lumen in the first input case 1, where it then flows through a first liquid outlet 17 of the first input lumen into the upper water holding drum 15, and the second recovery line 5 delivers the mixed liquid to a second input lumen in the first input case 1, where it then flows through a second liquid outlet 18 of the second input lumen into the lower water holding drum 16.

[0053] For example, if the first return line 4 continues to send the mixed liquid to the first input lumen and the upper water drum 15 after the water level in the upper water drum 15 reaches the set water level, the water level in the upper water drum 15 may exceed the set water level, preventing the upper water drum 15 from performing normal washing. At this time, if the washing time of the second input case 2 has not reached the set time, the second input case 2 will not be sufficiently washed. Therefore, while the water level in the lower water drum 16 has not reached the set water level, the second return line 5 can send the mixed liquid in the second input case 2 to the second input lumen and the lower water drum 16, allowing the washing time of the second input case 2 to reach the set time, and as a result, the remaining detergent in the second input case 2 can be sufficiently washed.

[0054] As shown in FIG. 2, the first recovery pipeline 4 and the second recovery pipeline 5 extend horizontally between the first input case 1 and the second input case 2, the first recovery pipeline 4, the second recovery pipeline 5 and the cleaning pipeline 3 are installed at the same height, and the first recovery pipeline 4 and the second recovery pipeline 5 are respectively provided on both the front and rear sides of the cleaning pipeline 3.

[0055] Since the first recovery pipeline 4 and the second recovery pipeline 5 extend horizontally, the length of the pipelines can be shortened, the space occupied can be reduced, and bending of the recovery pipelines can be avoided, the water flow can be accelerated, and the cleaning efficiency can be improved. In order to speed up the mixed liquid entering the first input case 1 from the second input case 2, a suction pump can be provided in the first recovery pipeline 4 and the second recovery pipeline 5.

[0056] In an embodiment of the present invention, a liquid storage case for storing detergent is provided within the second input case 2, and an input pipeline is provided between the first input case 1 and the second input case 2, with the liquid inlet of the input pipeline connected to the liquid outlet of the liquid storage case and the liquid outlet of the input pipeline connected to the liquid inlet of the first input case 1.

[0057] In an embodiment of the present invention, a liquid storage case for storing detergent is provided within the second dispenser case 2, and when dispensed, the dispenser pipe sends the detergent in the liquid storage case to the first dispenser case 1, and the detergent flows into the water holding drum by the water flow within the first dispenser case 1.

[0058] As shown in Figure 2, specifically, a first liquid storage case 6 and a second liquid storage case 7 are installed in parallel on the left and right sides within the second input case 2, and a first input pipeline 8 corresponding to the first liquid storage case 6 and a second input pipeline 9 corresponding to the second liquid storage case 7 are provided between the first input case 1 and the second input case 2, and the liquid outlet of the first input pipeline 8 and the liquid outlet of the second input pipeline 9 are both connected to the first input lumen and the second input lumen.

[0059] Two liquid storage cases are provided in the second input case 2, and different detergents or the same detergent may be stored in the two liquid storage cases. The two liquid storage cases are installed side by side on the left and right sides in the second input case 2, so that the space in the second input case 2 can be fully utilized.

[0060] The first input lumen communicates with the first water injection flow path, and the second input lumen communicates with the second water injection flow path. During water injection, the first water injection flow path draws water into the first input lumen and injects it into the upper water holding drum 15, and the second water injection flow path draws water into the second input lumen and injects it into the lower water holding drum 16.

[0061] During loading, the first loading conduit 8 loads the detergent in the first liquid storage case 6 into the first loading lumen and the second loading lumen, respectively, and the second loading conduit 9 loads the detergent in the second liquid storage case 7 into the first loading lumen and the second loading lumen, respectively, so that the detergent in the first liquid storage case 6 mixes with the detergent in the second liquid storage case 7 in the first loading lumen and then in the second loading lumen, and the water flow provided by the first water injection flow path causes the mixed detergent in the first loading lumen to flow into the upper water holding drum 15 through the first liquid outlet 17 of the first loading lumen, and the water flow provided by the second water injection flow path causes the mixed detergent in the second loading lumen to flow into the lower water holding drum 16 through the second liquid outlet 18 of the second loading lumen.

[0062] As shown in FIG. 2 , the first input pipeline 8 and the second input pipeline 9 extend horizontally between the first input case 1 and the second input case 2, the first input pipeline 8, the second input pipeline 9 and the cleaning pipeline 3 are installed at the same height, and the first input pipeline 8 and the second input pipeline 9 are arranged side by side in the front and rear and are provided between the cleaning pipeline 3 and the second recovery pipeline 5.

[0063] Since the first input pipe 8 and the second input pipe 9 extend horizontally, the length of the pipes can be shortened, the space occupied can be reduced, and bending of the input pipes can be avoided, which reduces obstacles to the detergent, speeds up the flow of the detergent, and improves the cleaning efficiency. In order to speed up the detergent entering the input cavity from the liquid storage case, a suction pump can be provided in the first input pipe 8 and the second input pipe 9.

[0064] As shown in Figures 3 and 4, a detection assembly is further provided in the second input case 2, and the detection assembly includes a position reach detection device 19 that detects whether the liquid storage case has been pushed into the second input case 2 and reached a position, and a liquid level detection device 20 that detects whether the liquid level in the second input case 2 has reached a set liquid level.

[0065] The position arrival detection device 19 detects whether the user has pushed or pulled the liquid storage case, and if the liquid storage case has been pushed or pulled, the arrival detection device 19 can store this and washes the second input case 2 when pouring water for rinsing other than the final time.

[0066] The probe of the position arrival detection device 19 is fitted into the second input case 2 from the top of the second input case 2 and suspended within the second input case 2, and when the liquid storage case is pushed into the second input case 2, the probe can detect the second input case 2, and the position arrival detection device 19 may be of various types such as a microswitch, a dry reed switch, etc.

[0067] The probe of the liquid level detection device 20 is fitted into the second input case 2 from the top of the second input case 2 and is suspended within the second input case 2, and the liquid level detection device 20 may be of various types such as a float switch.

[0068] If the liquid in the second input case 2 exceeds the set water level when cleaning the second input case 2, the liquid level may cover the steel needles. If the second input case 2 is further cleaned, the cleaning water may overflow, which may damage electrical equipment near the second input case 2 and pose a safety risk.

[0069] In an embodiment of the present invention, a third liquid storage case 10 and a fourth liquid storage case 11 are provided inside the first input case 1, arranged in parallel on the left and right sides, a third input pipeline is provided in the third liquid storage case 10, and a fourth input pipeline is provided in the fourth liquid storage case 11, and the liquid outlet of the third input pipeline and the liquid outlet of the fourth input pipeline are both connected to the first input lumen and the second input lumen.

[0070] In an embodiment of the present invention, two liquid storage cases are provided within the first dispenser case 1, and the two liquid storage cases may store different detergents or the same detergent. The two liquid storage cases are installed side by side on the left and right sides within the first dispenser case 1, thereby making full use of the space within the first dispenser case 1.

[0071] During loading, the third loading pipeline loads the detergent in the third liquid storage case 10 into the first loading lumen and the second loading lumen, respectively, the fourth loading pipeline loads the detergent in the fourth liquid storage case 11 into the first loading lumen and the second loading lumen, respectively, the detergent in the third liquid storage case 10 mixes with the detergent in the fourth liquid storage case 11 in the first loading lumen and then in the second loading lumen, the water flow provided by the first water injection flow path causes the mixed detergent in the first loading lumen to flow into the upper water holding drum 15 through the first liquid outlet 17 of the first loading lumen, and the water flow provided by the second water injection flow path causes the mixed detergent in the second loading lumen to flow into the lower water holding drum 16 through the second liquid outlet 18 of the second loading lumen, and both the third loading pipeline and the fourth loading pipeline are equipped with suction pumps.

[0072] As shown in FIG. 1 , the first liquid outlet 17 of the first input lumen communicates with the upper water holding drum 15 via the fifth input line 12, and the second liquid outlet 18 of the second input lumen communicates with the lower water holding drum 16 via the sixth input line 13.

[0073] When the first and second dispenser cases 1 and 2 dispense simultaneously, all of the detergents in all of the liquid storage cases are sucked into the first and second dispenser bores, and all of the detergents are mixed in the first and second dispenser bores, and the water flow causes the detergent mixed in the first dispenser bore to flow into the upper water holding drum 15, and the detergent mixed in the second dispenser bore to flow into the lower water holding drum 16.

[0074] In an embodiment of the present invention, when the time taken for the water flow to wash the second dispenser case 2 reaches the set wash time, or when the number of washes reaches the set number of washes, it is determined that there is no detergent remaining in the second dispenser case 2.

[0075] In an embodiment of the present invention, whether or not there is any detergent remaining in the second dispenser case 2 is determined based on whether or not the washing time has reached the set washing time or whether or not the number of washings has reached the set number of washings.

[0076] When the washing time reaches the set washing time or the number of washing times reaches the set number of washings, it is considered that there is no detergent remaining in the second dispenser case 2, and when the washing time has not reached the set washing time or the number of washings has not reached the set number of washings, it is considered that detergent remains in the second dispenser case 2, and it is necessary to continue pouring water into the second dispenser case 2.

[0077] Each time cleaning of the second input case 2 is completed, there may be residual cleaning water in the second input case 2 due to negative pressure. In this case, a liquid suction pump can be used to suck the residual water into the first input case 1, and then the water flow can be used to cause it to flow into the water holding drum.

[0078] If it is detected that the reservoir in the second dispenser 2 has been removed, there is residual detergent in the second dispenser 2, so the second dispenser 2 is washed before the final rinse. The reason why the wash water does not flow into the water holding drum together with the residual detergent during the final rinse is that if detergent is allowed to flow into the water holding drum, the final rinse may not be clean.

[0079] Furthermore, the laundry treatment device further includes a water holding drum, and the water pouring stream washes the second input case 2 at the same time that the first input case 1 pours water into the water holding drum, but if the washing time has not reached the set washing time when the water level in the water holding drum reaches the set water level, the next time water is poured into the water holding drum, the water pouring stream will wait for the second input case 2 to wash again.

[0080] At the same time that the first input case 1 injects water into the water holding drum, the water injection flow can pass through the cleaning pipe 3 from inside the first input case 1 into the second input case 2 and clean the second input case 2, thereby realizing that the water injection channel can inject water into the water holding drum during water injection and can also clean the second input case 2.

[0081] If the wash time does not reach the set wash time during the first water filling of the water holding drum, there will still be residual detergent in the second wash case, so the second input case 2 can be continuously washed after the water holding drum enters the second water filling, so that the total of the two wash times can reach the set wash time.

[0082] For example, when pouring water into the water holding drum during the washing stage, since there is already a large amount of washing water in the water holding drum, even if the water level in the water holding drum has not yet reached the set water level, the water level in the water holding drum can reach the set water level if water is poured into the water holding drum in a relatively short time. At this time, the washing time for the second input case 2 has not yet reached the set washing time, and therefore, when pouring water into the water holding drum during the rinsing stage, it is possible to wait to continue washing the second input case 2.

[0083] Furthermore, if the water level in the water drum reaches the set water level but the wash time has not yet reached the set wash time, the water inlet will continue to wash the second input case 2; even if the water level in the water drum is higher than the set water level, the water drum drain will be opened to discharge some of the water in the water drum, so the water inlet will continue to wash the second input case 2; if the water level in the water drum is higher than the set water level, the washing machine will not be able to operate normally; in this case, the washing of the second input case 2 must be stopped, and the washing machine will issue an alarm to inform the user that the clothes cannot be washed and to inform the user that some of the water in the water drum will be discharged so that the water level in the water drum is lower than the set water level, but the water inlet will continue to wash the second input case 2; after the wash time reaches the set wash time, the washing machine will start the wash program again.

[0084] The washing machine is provided with a time sensor, which is used to measure the washing time of the second input case 2, and the washing machine is provided with a controller, the time sensor, the liquid level detection device 20 and the position arrival detection device 19 are connected to the controller, and the time sensor transmits the measured washing time to the controller.

[0085] Furthermore, when the next water injection into the water holding drum is on standby and the water injection flow is to wash the second injection case 2 again, if the liquid level in the second injection case 2 exceeds the set liquid level, the liquid in the second injection case 2 is first sucked into the first injection case 1, and the second injection case 2 is again washed using the water injection flow.

[0086] When cleaning the second input case 2, if the liquid level detection device 20 detects that the liquid in the second input case 2 has exceeded a set water level, the liquid level in the second input case 2 is sucked into the first input case 1, preventing the liquid in the second input case 2 from overflowing due to excessive liquid in the second input case 2 and damaging electrical equipment near the second input case 2, which could pose a safety risk.

[0087] In an embodiment of the present invention, the laundry treatment device has an upper water holding drum 15 and a lower water holding drum 16, and the water flow after washing the second input case 2 enters the upper water holding drum 15 and the lower water holding drum 16, or the water flow after washing the second input case 2 alternatively enters the upper water holding drum 15 and the lower water holding drum 16.

[0088] Furthermore, the upper water holding drum 15 executes the water injection program prior to the lower water holding drum 16, and the water flow after washing the second input case 2 first enters the upper water holding drum 15. However, when the lower water holding drum 16 executes the water injection program, if the water level in the upper water holding drum 15 has not reached the set water level and the washing time has not reached the set washing time, the water flow after washing the second input case 2 will enter both the upper water holding drum 15 and the lower water holding drum 16.

[0089] Furthermore, the upper water holding drum 15 executes the water injection program before the lower water holding drum 16, and the water flow after washing the second input case 2 first enters the upper water holding drum 15. However, if the water level in the upper water holding drum 15 reaches the set water level but the washing time has not yet reached the set washing time, it is determined whether the lower water holding drum 16 is executing the water injection program. If it is, when the lower water holding drum 16 is filling with water, it waits for the water flow after washing the second input case 2 to enter the lower water holding drum 16. [Example]

[0090] As shown in Figure 5, the present invention provides a control method for a clothing processing device, which has a first input case 1 and a second input case 2, the first input case 1 is connected to the second input case 2 via a cleaning line 3, the clothing processing device has a cleaning program, and when the cleaning program is executed, the cleaning line 3 is opened and the second input case 2 is cleaned by the water flow flowing through the first input case 1 and the cleaning line 3.

[0091] In an embodiment of the present invention, the second input case 2 is cleaned by the water flow flowing through the first input case 1 and the cleaning pipe 3, preventing detergent from remaining in the second input case 2 and reducing detergent waste.

[0092] The above-mentioned clothing processing devices include the following types:

[0093] First type of clothing treatment device: The clothing treatment device is a drum type washing machine, which comprises a housing 14, an outer drum, an inner drum rotatably arranged within the outer drum, and an input assembly, the input assembly including a first input case 1 and a second input case 2, the inner drum is an inner drum without holes, and the inner drum serves as a water holding drum when washing clothes alone, and the first input case 1 and the second input case 2 input detergent into the inner drum, or the outer drum serves as a water holding drum, and the first input case 1 and the second input case 2 input detergent into the outer drum.

[0094] Second type of clothing treatment device: The clothing treatment device is a two-drum washing machine, which includes a housing 14, a first outer drum and a second outer drum provided in the housing 14, a first inner drum provided in the first outer drum, a second inner drum provided in the second outer drum, and an input assembly, the input assembly including a first input case 1 and a second input case 2, the first inner drum and the second inner drum are inner drums without holes, and the inner drum is used as a water holding drum when washing clothes alone, and the first input The case 1 and the second input case 2 input detergent into the first inner drum and the second inner drum, or the first outer drum and the second outer drum are water holding drums, and the first input case 1 and the second input case 2 input detergent into the first outer drum and the second outer drum, and the housing 14 may be a first housing 14 and a second housing 14 independent of each other, and the first outer drum and the first inner drum are provided within the first housing 14, and the second outer drum and the second inner drum are provided within the second housing 14.

[0095] As shown in Fig. 1, in the second type of laundry treatment device, the first input case 1 and the second input case 2 are preferably provided on the upper part of the housing 14 and located above all the drums, the liquid outlet of the second input case 2 is connected to the liquid inlet of the first input case 1, the liquid outlets of the first input case 1 are connected to the upper water holding drum 15 and the lower water holding drum 16, respectively, and the first input case 1 is connected to an external water injection pipe. In addition, the first input case 1 is provided with a water injection channel connected to the washing pipe 3 and a water injection channel for washing the detergent in the first input case 1 and injecting water into the water holding drum, and both water injection channels are connected to an external water injection pipe. The input device may include not only the first input case 1 and the second input case 2 but also other input cases, and the types of detergent dispensed by each input case may be the same or different.

[0096] A liquid storage case for storing detergent is provided within the second input case 2, and the liquid storage case is provided so as to be pushable and removable within the second input case 2. When the liquid storage case is removed, liquid may leak, and if the liquid leakage is not treated for a long period of time, it may dry out and harden, or mold may grow. Therefore, the remaining detergent in the second input case 2 is washed using the cleaning pipe 3.

[0097] During addition, the detergent in the second addition case 2 is sucked into the first addition case 1 and mixed with the detergent in the first addition case 1, and the mixed liquid is forced into the upper water holding drum 15 and / or the lower water holding drum 16 by the water flow entering from the first addition case 1.

[0098] During cleaning, the water flow flowing out from the water injection flow path of the first input case 1 passes through the cleaning pipe 3 and enters the second input case 2 to wash away any detergent remaining in the second input case 2, and the mixed liquid obtained after cleaning the second input case 2 passes through the first input case 1 and enters the upper water holding drum 15 and / or the lower water holding drum 16.

[0099] As shown in Figure 2, the arrows in the pipelines in Figure 2 indicate the direction of fluid flow. In this embodiment of the present invention, the first input case 1 and the second input case 2 are installed side by side, the water outlet of the water injection flow path is provided in the first input case 1 and is installed facing the water inlet of the second input case 2, and the cleaning pipeline 3 is provided between the first input case 1 and the second input case 2 and extends horizontally between the first input case 1 and the second input case 2.

[0100] In this embodiment of the present invention, specifically, the first dispenser case 1 and the second dispenser case 2 are arranged on the top of the housing 14 and are located above all the drums, the first dispenser case 1 is arranged on the left side of the housing 14, and the second dispenser case 2 is arranged on the right side of the housing 14, the first dispenser case 1 and the second dispenser case 2 have the same shape and specifications, and are installed side by side, which makes it convenient to manually dispense detergent and makes full use of the space in the housing 14.

[0101] The first input case 1 comprises a case body and a case lid, the case lid comprising an upper cover and a lower cover which engage with each other, and the upper cover engages with the lower cover, thereby forming several independent water injection channels inside the case lid, a water injection channel is provided on the top of the first input case 1, the water outlet of the water injection channel is installed opposite the water inlet face of the second input case 2, and a cleaning pipe 3 is provided between the first input case 1 and the second input case 2, thereby shortening the length of the cleaning pipe 3, reducing the space occupied, as well as reducing cleaning time and improving cleaning efficiency, a suction pump can be provided in the cleaning pipe 3 to speed up the flow of cleaning water from the first input case 1 through the cleaning pipe 3 into the second input case 2 to clean the second input case 2, and the cleaning pipe 3 extends horizontally between the first input case 1 and the second input case 2, avoiding bending of the cleaning pipe 3, reducing obstacles to the water flow and speeding up the water flow.

[0102] As shown in Figure 2, in an embodiment of the present invention, a recovery pipeline is provided between the first input case 1 and the second input case 2 to recover the mixed liquid obtained by cleaning the second input case 2, and the liquid inlet of the recovery pipeline is connected to the liquid outlet of the second input case 2, and the liquid outlet of the recovery pipeline is connected to the liquid inlet of the first input case 1, and the first input case 1 has a liquid outlet.

[0103] In an embodiment of the present invention, the water flow enters the second input case 2 from the cleaning pipe to clean the second input case 2, and a mixed liquid of water and detergent is obtained after cleaning. In order to fully utilize the mixed liquid in the water holding drum, a recovery pipe is provided between the first input case 1 and the second input case 2, and the recovery pipe injects the mixed liquid from the second input case 2 into the first input case 1, and the mixed liquid further enters the water holding drum through the liquid outlet of the first input case 1.

[0104] 2, specifically, a first input lumen and a second input lumen are provided within first input case 1, a first return line 4 corresponding to the first input lumen and a second return line 5 corresponding to the second input lumen are provided between first input case 1 and second input case 2, the first input lumen has a first liquid outlet 17 provided at the bottom of first input case 1, and the second input lumen has a second liquid outlet 18 provided at the side of first input case 1. First liquid outlet 17 of the first input lumen communicates with upper water holding drum 15, and second liquid outlet 18 of the second input lumen communicates with lower water holding drum 16.

[0105] During recovery, the first recovery line 4 delivers the mixed liquid to a first input lumen in the first input case 1, where it then flows through a first liquid outlet 17 of the first input lumen into the upper water holding drum 15, and the second recovery line 5 delivers the mixed liquid to a second input lumen in the first input case 1, where it then flows through a second liquid outlet 18 of the second input lumen into the lower water holding drum 16.

[0106] For example, if the first return line 4 continues to send the mixed liquid to the first input lumen and the upper water drum 15 after the water level in the upper water drum 15 reaches the set water level, the water level in the upper water drum 15 may exceed the set water level, preventing the upper water drum 15 from performing normal washing. At this time, if the washing time of the second input case 2 has not reached the set time, the second input case 2 will not be sufficiently washed. Therefore, while the water level in the lower water drum 16 has not reached the set water level, the second return line 5 can send the mixed liquid in the second input case 2 to the second input lumen and the lower water drum 16, allowing the washing time of the second input case 2 to reach the set time, and as a result, the remaining detergent in the second input case 2 can be sufficiently washed.

[0107] Furthermore, the first recovery pipeline 4 and the second recovery pipeline 5 extend horizontally between the first input case 1 and the second input case 2, the first recovery pipeline 4, the second recovery pipeline 5 and the cleaning pipeline 3 are installed at the same height, and the first recovery pipeline 4 and the second recovery pipeline 5 are respectively provided on both the front and rear sides of the cleaning pipeline 3.

[0108] Since the first recovery pipeline 4 and the second recovery pipeline 5 extend horizontally, the length of the pipelines can be shortened, the space occupied can be reduced, and bending of the recovery pipelines can be avoided, the water flow can be accelerated, and the cleaning efficiency can be improved. In order to speed up the mixed liquid entering the first input case 1 from the second input case 2, a suction pump can be provided in the first recovery pipeline 4 and the second recovery pipeline 5.

[0109] As shown in FIG. 2, in an embodiment of the present invention, a liquid storage case for storing detergent is provided within the second input case 2, and an input pipeline is provided between the first input case 1 and the second input case 2, with the liquid inlet of the input pipeline connected to the liquid outlet of the liquid storage case and the liquid outlet of the input pipeline connected to the liquid inlet of the first input case 1.

[0110] In an embodiment of the present invention, a liquid storage case for storing detergent is provided within the second dispenser case 2, and when dispensed, the dispenser pipe sends the detergent in the liquid storage case to the first dispenser case 1, and the detergent flows into the water holding drum by the water flow within the first dispenser case 1.

[0111] As shown in Figures 1 and 2, specifically, a first liquid storage case 6 and a second liquid storage case 7 are installed in parallel on the left and right sides within the second input case 2, and a first input pipeline 8 corresponding to the first liquid storage case 6 and a second input pipeline 9 corresponding to the second liquid storage case 7 are provided between the first input case 1 and the second input case 2, and the liquid outlet of the first input pipeline 8 and the liquid outlet of the second input pipeline 9 are both connected to the first input lumen and the second input lumen.

[0112] Two liquid storage cases are provided in the second input case 2, and different detergents or the same detergent may be stored in the two liquid storage cases. The two liquid storage cases are installed side by side on the left and right sides in the second input case 2, so that the space in the second input case 2 can be fully utilized.

[0113] The first input lumen communicates with the first water injection flow path, and the second input lumen communicates with the second water injection flow path. During water injection, the first water injection flow path draws water into the first input lumen and injects it into the upper water holding drum 15, and the second water injection flow path draws water into the second input lumen and injects it into the lower water holding drum 16.

[0114] During loading, the first loading conduit 8 loads the detergent in the first liquid storage case 6 into the first loading lumen and the second loading lumen, respectively, and the second loading conduit 9 loads the detergent in the second liquid storage case 7 into the first loading lumen and the second loading lumen, respectively, so that the detergent in the first liquid storage case 6 mixes with the detergent in the second liquid storage case 7 in the first loading lumen and then in the second loading lumen, and the water flow provided by the first water injection flow path causes the mixed detergent in the first loading lumen to flow into the upper water holding drum 15 through the first liquid outlet 17 of the first loading lumen, and the water flow provided by the second water injection flow path causes the mixed detergent in the second loading lumen to flow into the lower water holding drum 16 through the second liquid outlet 18 of the second loading lumen.

[0115] Furthermore, the first input pipeline 8 and the second input pipeline 9 extend horizontally between the first input case 1 and the second input case 2, the first input pipeline 8, the second input pipeline 9 and the cleaning pipeline 3 are installed at the same height, and the first input pipeline 8 and the second input pipeline 9 are arranged side by side in the front and back and are provided between the cleaning pipeline 3 and the second recovery pipeline 5.

[0116] Since the first input pipe 8 and the second input pipe 9 extend horizontally, the length of the pipes can be shortened, the space occupied can be reduced, and bending of the input pipes can be avoided, which reduces obstacles to the detergent, speeds up the flow of the detergent, and improves the cleaning efficiency. In order to speed up the detergent entering the input cavity from the liquid storage case, a suction pump can be provided in the first input pipe 8 and the second input pipe 9.

[0117] As shown in Figures 3 and 4, a detection assembly is further provided in the second input case 2, and the detection assembly includes a position reach detection device 19 that detects whether the liquid storage case has been pushed into the second input case 2 and reached a position, and a liquid level detection device 20 that detects whether the liquid level in the second input case 2 has reached a set liquid level.

[0118] The position arrival detection device 19 detects whether the user has pushed or pulled the liquid storage case, and if the liquid storage case has been pushed or pulled, the arrival detection device 19 can store this and washes the second input case 2 when pouring water for rinsing other than the final time.

[0119] The probe of the position arrival detection device 19 is fitted into the second input case 2 from the top of the second input case 2 and suspended within the second input case 2, and when the liquid storage case is pushed into the second input case 2, the probe can detect the second input case 2, and the position arrival detection device 19 may be of various types such as a microswitch, a dry reed switch, etc.

[0120] The probe of the liquid level detection device 20 is fitted into the second input case 2 from the top of the second input case 2 and is suspended within the second input case 2, and the liquid level detection device 20 may be of various types such as a float switch.

[0121] If the liquid in the second input case 2 exceeds the set water level when cleaning the second input case 2, the liquid level may cover the steel needles. If the second input case 2 is further cleaned, the cleaning water may overflow, which may damage electrical equipment near the second input case 2 and pose a safety risk.

[0122] In an embodiment of the present invention, a third liquid storage case 10 and a fourth liquid storage case 11 are provided inside the first input case 1, arranged in parallel on the left and right sides, a third input pipeline is provided in the third liquid storage case 10, and a fourth input pipeline is provided in the fourth liquid storage case 11, and the liquid outlet of the third input pipeline and the liquid outlet of the fourth input pipeline are both connected to the first input lumen and the second input lumen.

[0123] In an embodiment of the present invention, two liquid storage cases are provided within the first dispenser case 1, and the two liquid storage cases may store different detergents or the same detergent. The two liquid storage cases are installed side by side on the left and right sides within the first dispenser case 1, thereby making full use of the space within the first dispenser case 1.

[0124] During loading, the third loading pipeline loads the detergent in the third liquid storage case 10 into the first loading lumen and the second loading lumen, respectively, the fourth loading pipeline loads the detergent in the fourth liquid storage case 11 into the first loading lumen and the second loading lumen, respectively, the detergent in the third liquid storage case 10 mixes with the detergent in the fourth liquid storage case 11 in the first loading lumen and then in the second loading lumen, the water flow provided by the first water injection flow path causes the mixed detergent in the first loading lumen to flow into the upper water holding drum 15 through the first liquid outlet 17 of the first loading lumen, and the water flow provided by the second water injection flow path causes the mixed detergent in the second loading lumen to flow into the lower water holding drum 16 through the second liquid outlet 18 of the second loading lumen, and both the third loading pipeline and the fourth loading pipeline are equipped with suction pumps.

[0125] As shown in FIG. 1 , the first liquid outlet 17 of the first input lumen communicates with the upper water holding drum 15 via the fifth input line 12, and the second liquid outlet 18 of the second input lumen communicates with the lower water holding drum 16 via the sixth input line 13.

[0126] When the first and second dispenser cases 1 and 2 dispense simultaneously, all of the detergents in all of the liquid storage cases are sucked into the first and second dispenser bores, and all of the detergents are mixed in the first and second dispenser bores, and the water flow causes the detergent mixed in the first dispenser bore to flow into the upper water holding drum 15, and the detergent mixed in the second dispenser bore to flow into the lower water holding drum 16.

[0127] In an embodiment of the present invention, when the time taken for the water flow to wash the second dispenser case 2 reaches the set wash time, or when the number of washes reaches the set number of washes, it is determined that there is no detergent remaining in the second dispenser case 2.

[0128] In an embodiment of the present invention, whether or not there is any detergent remaining in the second dispenser case 2 is determined based on whether or not the washing time has reached the set washing time or whether or not the number of washings has reached the set number of washings.

[0129] When the washing time reaches the set washing time or the number of washing times reaches the set number of washings, it is considered that there is no detergent remaining in the second dispenser case 2, and when the washing time has not reached the set washing time or the number of washings has not reached the set number of washings, it is considered that detergent remains in the second dispenser case 2, and it is necessary to continue pouring water into the second dispenser case 2.

[0130] If it is detected that the reservoir in the second dispenser 2 has been removed, there is residual detergent in the second dispenser 2, so the second dispenser 2 is washed before the final rinse. The reason why the wash water does not flow into the water holding drum together with the residual detergent during the final rinse is that if detergent is allowed to flow into the water holding drum, the final rinse may not be clean.

[0131] As shown in FIG. 5, the laundry treatment device further includes a water drum, and when the first input case 1 injects water into the water drum, the water flow washes the second input case 2 at the same time. If the washing time has not yet reached the set washing time when the water level in the water drum reaches the set water level, the next time water is injected into the water drum, the water flow will wait for the water flow to wash the second input case 2 again.

[0132] At the same time that the first input case 1 injects water into the water holding drum, the water injection flow can pass through the cleaning pipe 3 from inside the first input case 1 into the second input case 2 and clean the second input case 2, thereby realizing that the water injection channel can inject water into the water holding drum during water injection and can also clean the second input case 2.

[0133] If the wash time does not reach the set wash time during the first water filling of the water holding drum, there will still be residual detergent in the second wash case, so the second input case 2 can be continuously washed after the water holding drum enters the second water filling, so that the total of the two wash times can reach the set wash time.

[0134] Each time cleaning of the second input case 2 is completed, there may be residual cleaning water in the second input case 2 due to negative pressure. In this case, a liquid suction pump can be used to suck the residual water into the first input case 1, and then the water flow can be used to cause it to flow into the water holding drum.

[0135] For example, when pouring water into the water holding drum during the washing stage, since there is already a large amount of washing water in the water holding drum, even if the water level in the water holding drum has not yet reached the set water level, the water level in the water holding drum can reach the set water level if water is poured into the water holding drum in a relatively short time. At this time, the washing time for the second input case 2 has not yet reached the set washing time, and therefore, when pouring water into the water holding drum during the rinsing stage, it is possible to wait to continue washing the second input case 2.

[0136] Furthermore, if the water level in the water drum reaches the set water level but the wash time has not yet reached the set wash time, the water inlet will continue to wash the second input case 2; even if the water level in the water drum is higher than the set water level, the water drum drain will be opened to discharge some of the water in the water drum, so the water inlet will continue to wash the second input case 2; if the water level in the water drum is higher than the set water level, the washing machine will not be able to operate normally; in this case, the washing of the second input case 2 must be stopped, and the washing machine will issue an alarm to inform the user that the clothes cannot be washed and to inform the user that some of the water in the water drum will be discharged so that the water level in the water drum is lower than the set water level, but the water inlet will continue to wash the second input case 2; after the wash time reaches the set wash time, the washing machine will start the wash program again.

[0137] The washing machine is provided with a time sensor, which is used to measure the washing time of the second input case 2, and the washing machine is provided with a controller, the time sensor, the liquid level detection device 20 and the position arrival detection device 19 are connected to the controller, and the time sensor transmits the measured washing time to the controller.

[0138] Furthermore, when the next water injection into the water holding drum is on standby and the water injection flow is to wash the second injection case 2 again, if the liquid level in the second injection case 2 exceeds the set liquid level, the liquid in the second injection case 2 is first sucked into the first injection case 1, and the second injection case 2 is again washed using the water injection flow.

[0139] When cleaning the second input case 2, if the liquid level detection device 20 detects that the liquid in the second input case 2 has exceeded a set water level, the liquid level in the second input case 2 is sucked into the first input case 1, preventing the liquid in the second input case 2 from overflowing due to excessive liquid in the second input case 2 and damaging electrical equipment near the second input case 2, which could pose a safety risk.

[0140] In an embodiment of the present invention, the laundry treatment device has an upper water holding drum 15 and a lower water holding drum 16, and the water flow after washing the second input case 2 enters the upper water holding drum 15 and the lower water holding drum 16, or the water flow after washing the second input case 2 alternatively enters the upper water holding drum 15 and the lower water holding drum 16.

[0141] Furthermore, the upper water holding drum 15 executes the water injection program prior to the lower water holding drum 16, and the water flow after washing the second input case 2 first enters the upper water holding drum 15. However, when the lower water holding drum 16 executes the water injection program, if the water level in the upper water holding drum 15 has not reached the set water level and the washing time has not reached the set washing time, the water flow after washing the second input case 2 will enter both the upper water holding drum 15 and the lower water holding drum 16.

[0142] Furthermore, the upper water holding drum 15 executes the water injection program before the lower water holding drum 16, and the water flow after washing the second input case 2 first enters the upper water holding drum 15. However, if the water level in the upper water holding drum 15 reaches the set water level but the washing time has not yet reached the set washing time, it is determined whether the lower water holding drum 16 is executing the water injection program. If it is, when the lower water holding drum 16 is filling with water, it waits for the water flow after washing the second input case 2 to enter the lower water holding drum 16.

[0143] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above through preferred embodiments, this is not intended to limit the present invention. Anyone familiar with the technology of this patent may use the technical content presented above to create equivalent embodiments of equivalent modifications by making slight changes or additions, and the implementation methods of the above embodiments may also be further combined or substituted, without departing from the content of the technical solutions of the present invention.
