Description

Technical Field

[0001] The present invention belongs to the technical field of clothing treatment, and specifically relates to a clothing treatment device, and also relates to a control method for the clothing treatment device. Background Art

[0002] A washing machine is a commonly used household appliance for washing clothes. The drum assembly of the washing machine is arranged in the machine body, and the rotation of the drum assembly realizes the cleaning of clothes, providing a lot of convenience for people's daily life.

[0003] Nowadays, the classified washing of clothes has gradually entered the needs of users. More and more users pay attention to classifying and washing clothes for children, adults, the elderly, underwear, etc., to avoid cross-contamination caused by mixed washing. Conventional washing machines do not have the function of classified washing of clothes. It is necessary to prepare multiple washing machines or wash clothes in batches with a single washing machine, which requires more space to place multiple washing machines or takes a lot of time. Therefore, multi-drum washing machines have emerged. Generally, a multi-drum washing machine includes a large-capacity laundry drum assembly and a small-capacity laundry drum assembly. The large-capacity laundry drum assembly can be used to wash adult clothes, and the small-capacity laundry drum assembly can be used to wash children's clothes, underwear or socks. In this way, the pollution caused by the mixed washing of adult clothes and children's clothes or underwear is effectively avoided, and the classified washing of clothes is realized.

[0004] The Chinese invention patent with the application number CN201910250293.1 discloses a multi-drum washing machine, which relates to the technical field of washing machines and is invented to provide a multi-drum washing machine that can reduce the vibration of the upper part of the washing machine and reduce noise. The multi-drum washing machine includes a machine shell, and a laundry drum assembly is arranged in the machine shell. The laundry drum assembly includes: at least two upper laundry drums. The upper laundry drums are pulsator-type laundry drums, and each pulsator-type laundry drum includes an inner drum and an outer drum located outside the inner drum. There is a distance between every two outer drums; a lower laundry drum, and the lower laundry drum is located below the upper laundry drums; an upper shock-absorbing structure, and the upper shock-absorbing structure is used to shock-absorb the upper laundry drums, and the upper laundry drums are connected to the machine shell through the upper shock-absorbing structure.

[0005] However, in the above solution, each drum assembly is independently arranged, and there is no cooperation between the drum assemblies. The usage frequency of individual drum assemblies is too low. Generally, the usage frequency of the large-capacity drum assembly is relatively high, and the usage frequency of the small-capacity drum assembly is relatively low. Moreover, the drainage time of the large-capacity drum assembly is too long, increasing the total laundry time of the clothing treatment device and affecting the user experience.

[0006] Therefore, designing a clothing treatment device that can accelerate the drainage efficiency has become a technical problem that needs to be solved urgently by those skilled in the art.

[0007] In view of this, the present invention is specifically proposed. Summary of the Invention

[0008] The present invention provides a laundry treatment device. By arranging an inter-cylinder connecting pipe between the main washing cylinder assembly and the auxiliary washing cylinder assembly, the idle auxiliary washing cylinder assembly can store a certain volume of washing water discharged from the main washing cylinder assembly, shortening the drainage time of the main washing cylinder assembly and solving the problem of low laundry efficiency caused by too long drainage time in existing laundry treatment devices.

[0009] To solve the above technical problems, the basic concept of the technical solution adopted in the present invention is:

[0010] A laundry treatment device includes a cabinet and components installed in the cabinet:

[0011] A main washing cylinder assembly;

[0012] An auxiliary washing cylinder assembly, arranged below the main washing cylinder assembly;

[0013] A drainage pipeline, the first end of which is respectively communicated with the main washing cylinder assembly and the auxiliary washing cylinder assembly through drainage branch pipes, and the second end extends to the outside of the cabinet;

[0014] An inter-cylinder connecting pipe is arranged between the bottom of the main washing cylinder assembly and the auxiliary washing cylinder assembly, and is used for discharging part of the washing water into the idle auxiliary washing cylinder assembly when the main washing cylinder assembly drains water.

[0015] Furthermore, drainage valves are respectively arranged between the main washing cylinder assembly and the auxiliary washing cylinder assembly and the drainage pipeline;

[0016] An on-off valve is arranged between the main washing cylinder assembly and the auxiliary washing cylinder assembly.

[0017] Furthermore, the maximum washing capacity of the main washing cylinder assembly is greater than or equal to the maximum washing capacity of the auxiliary washing cylinder assembly, and the axis of the auxiliary washing cylinder assembly is parallel to the axis of the main washing cylinder assembly.

[0018] Furthermore, the main washing cylinder assembly is arranged in the upper middle part of the cabinet, and there are two auxiliary washing cylinder assemblies, which are respectively arranged on the left and right sides of the axis of the main washing cylinder assembly below the main washing cylinder assembly;

[0019] Preferably, the two auxiliary washing cylinder assemblies are symmetric about the vertical bisecting plane of the axis of the main washing cylinder assembly.

[0020] Furthermore, the barrel openings of the main washing cylinder assembly and the auxiliary washing cylinder assembly are respectively coaxially arranged at the front ends of the main washing cylinder assembly and the auxiliary washing cylinder assembly. Clothing feeding ports corresponding to the barrel openings are arranged on the front side wall of the cabinet, and the clothing feeding ports are connected to the barrel openings through a window gasket structure;

[0021] The rear ends of the main washing drum assembly and the auxiliary washing drum assembly are connected to the box body through shock absorber assemblies.

[0022] Furthermore, the axial extension length of the two auxiliary washing drum assemblies is less than that of the main washing drum assembly;

[0023] The shock absorber assemblies for installing the auxiliary washing drum assemblies and the shock absorber assemblies for installing the main washing drum assembly are arranged axially misaligned along the main washing drum assembly.

[0024] Furthermore, fixing columns are arranged inside the box body, below the main washing drum assembly and parallel to the axis of the main washing drum assembly; the shock absorber assemblies for installing the auxiliary washing drum assemblies include:

[0025] At least one first shock absorber connected between the auxiliary washing drum assembly and the side wall of the box body on the side away from the fixing column, at least one second shock absorber connected between the auxiliary washing drum assembly and the bottom side wall of the box body, and at least one third shock absorber connected between the auxiliary washing drum assembly and the fixing column.

[0026] Furthermore, the fixing columns are arranged between the two auxiliary washing drum assemblies and extend in the horizontal direction;

[0027] Preferably, the height of the fixing columns is flush with the axis height of the two auxiliary washing drum assemblies.

[0028] The present invention also provides a control method for the above-mentioned clothing treatment device, including the following steps:

[0029] When the main washing drum assembly drains water, part of the water is discharged into the idle auxiliary washing drum assembly, and at the same time, the connection between the idle auxiliary washing drum assembly and the drainage pipeline is disconnected;

[0030] After the main washing drum assembly finishes draining water, the idle auxiliary washing drum assembly is connected to the drainage pipeline, and the washing water temporarily stored in the idle auxiliary washing drum assembly is discharged.

[0031] Furthermore, during the process of the auxiliary washing drum assembly executing the washing program, if there is still a demand for water intake in the future, and at the same time, the main washing drum assembly is idle, then before the auxiliary washing drum assembly intakes water, water is first intaken into the main washing drum assembly;

[0032] When the auxiliary washing drum assembly intakes water, the main washing drum assembly and the water inlet pipeline are used to supply water to the auxiliary washing drum assembly simultaneously;

[0033] Preferably, the water intake volume of the auxiliary washing drum assembly is divided into two parts. The first part is introduced into the main washing drum assembly before the water intake node of the auxiliary washing drum assembly, and the second part is introduced into the auxiliary washing drum assembly at the water intake node of the auxiliary washing drum assembly. When the second part is introduced, the water in the main washing drum assembly is also introduced into the auxiliary washing drum assembly;

[0034] The ratio of the volume of the first inlet water to the volume of the second inlet water is equal to the ratio of the flow rate of water supplied from the main washing cylinder assembly to the auxiliary washing cylinder assembly to the flow rate of water supplied from the water inlet pipeline to the auxiliary washing cylinder assembly.

[0035] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0036] 1. By arranging an inter-cylinder connecting pipe between the main washing cylinder assembly and the auxiliary washing cylinder assembly, the present invention enables the idle auxiliary washing cylinder assembly to store a certain volume of washing water discharged from the main washing cylinder assembly. That is, when draining the main washing cylinder assembly, when opening the drain valve of the main washing cylinder assembly, opening the inter-cylinder connecting pipe can accelerate the drainage speed of the washing water in the main washing cylinder assembly and shorten the drainage time of the main washing cylinder assembly.

[0037] 2. By arranging that when the main washing cylinder assembly is idle, a certain amount of washing water is pre-stored, and when the auxiliary washing cylinder assembly is filling with water, the water inlet pipeline and the main washing cylinder assembly are used to supply water to the auxiliary washing cylinder assembly simultaneously, the present invention can shorten the water inlet duration of the auxiliary washing cylinder assembly and further improve the laundry efficiency of the laundry treatment device.

[0038] 3. By arranging that the main washing cylinder assembly and the auxiliary washing cylinder assembly are respectively installed in the box body through shock absorber assemblies, the main washing cylinder assembly and the auxiliary washing cylinder assembly will not interfere with each other during laundry, thereby ensuring the shock absorption effect on each washing cylinder assembly.

[0039] Meanwhile, the present invention has a simple structure and remarkable effects, and is suitable for popularization and use.

By providing the fixing column 15, it is possible to avoid interference between the shock absorber assemblies for installing different drum assemblies and ensure the shock absorption effect on each drum assembly.

[0068] Preferably, in this embodiment, the extending direction of the fixing column 15 is parallel to the axis of the main washing drum assembly 2.

[0069] Specifically, the fixing column 15 is arranged between the two auxiliary washing drum assemblies 3 and extends in the horizontal direction. The height of the fixing column 15 is flush with the axis height of the two auxiliary washing drum assemblies 3.

[0070] Preferably, in this embodiment, the axis of the fixed column 15 and the axis of the main washing cylinder assembly 2 are in the same vertical plane, and the two auxiliary washing cylinder assemblies 3 have the same model.

[0071] Specifically, in this embodiment, the maximum washing capacity of the auxiliary washing cylinder assembly 3 is less than that of the main washing cylinder assembly 2. Specifically, for ordinary clothing treatment equipment, the maximum washing capacity of the main washing cylinder assembly 2 can be set from 6 kg to 10 kg, and the maximum washing capacity of the auxiliary washing cylinder assembly 3 can be set from 1 kg to 2.5 kg. For wall-mounted clothing treatment equipment, the maximum washing capacity of the main washing cylinder assembly 2 can be set from 3 kg to 5 kg, and the maximum washing capacity of the auxiliary washing cylinder assembly 3 can be set from 0.2 kg to 1 kg.

[0072] Preferably, the two auxiliary washing cylinder assemblies 3 are symmetric about the left and right of the axial vertical bisecting plane of the main washing cylinder assembly 2.

[0073] The barrel openings of the main washing cylinder assembly 2 and the auxiliary washing cylinder assemblies 3 are coaxially arranged at the front ends of the main washing cylinder assembly 2 and the auxiliary washing cylinder assemblies 3 respectively.

[0075] In this embodiment, the clothing feeding port corresponding to the barrel opening of the main washing cylinder assembly 2 and the clothing feeding port corresponding to the barrel opening of the auxiliary washing cylinder assembly 3 are both arranged on the front side wall of the box body 1. A door body for closing the clothing feeding port is arranged on the front side wall of the box body 1.

[0076] In some possible embodiments, the door body is provided with one, and the shape of the door body is adapted to the shape of the front side wall of the box body 1 of the clothing treatment equipment. The door body can open or close the clothing feeding port of the main washing cylinder assembly 2 and the clothing feeding ports of the two auxiliary washing cylinder assemblies 3 at the same time.

[0077] In some other possible embodiments, the door body is provided with three, and a door body is respectively arranged at the clothing feeding port of each washing cylinder assembly.

[0078] Specifically, in this embodiment, one end of the door body is hinged to the front side wall of the box body 1, and the other end is clamped to the front side wall of the box body 1.

[0079] In this embodiment, observation windows for users to observe the washing conditions inside each washing cylinder assembly are respectively provided in each door body part.

[0080] As Figure 2 and Figure 3 shown, in this embodiment, the laundry treatment device further includes a water inlet pipeline 11. One end of the water inlet pipeline 11 is used to be connected to a water source, and the other end of the water inlet pipeline 11 is provided with three water inlet branch pipes 12. The end of the water inlet pipeline 11 far from the water source is respectively communicated with the main washing cylinder assembly 2 and two auxiliary washing cylinder assemblies 3 through the three water inlet branch pipes 12.

[0081] In this embodiment, a water inlet valve is respectively provided on each of the three water inlet branch pipes 12, and / or a switching valve is provided at the connection between the water inlet branch pipe 12 and the water inlet pipeline 11, and water is selectively supplied to any one or more washing cylinder assemblies through the water inlet valve and / or the switching valve.

[0082] In this embodiment, the laundry treatment device further includes a drainage pipeline 13. One end of the drainage pipeline 13 is respectively communicated with the main washing cylinder assembly 2 and the auxiliary washing cylinder assemblies 3 through drainage branch pipes 14, and the second end extends to the outside of the cabinet 1. Specifically, three drainage branch pipes 14 are provided, which are respectively connected to the bottoms of the two auxiliary washing cylinder assemblies 3 and one main washing cylinder assembly 2, and drainage valves are respectively provided between the main washing cylinder assembly 2 and each auxiliary washing cylinder assembly 3 and the drainage pipeline 13.

[0083] Preferably, in this embodiment, an inter-cylinder connecting pipe 4 is provided between the bottom of the main washing cylinder assembly 2 and the auxiliary washing cylinder assemblies 3, and a cut-off valve is provided on the inter-cylinder connecting pipe 4 between the main washing cylinder assembly 2 and the auxiliary washing cylinder assemblies 3.

[0084] In this embodiment, the inter-cylinder connecting pipe 4 is provided as a flexible pipe.

[0085] Preferably, in this embodiment, an inter-cylinder connecting pipe 4 is provided between the bottom of the main washing cylinder assembly 2 and the auxiliary washing cylinder assemblies 3, and a cut-off valve is provided on the inter-cylinder connecting pipe 4.

[0086] By providing the inter-cylinder connecting pipe 4 between the main washing cylinder assembly 2 and the auxiliary washing cylinder assemblies 3, when the main washing cylinder assembly 2 does not execute a washing program, it can be used to store a certain amount of washing water. When the auxiliary washing cylinder assemblies 3 are filling with water, the main washing cylinder assembly 2 and the water inlet pipeline 11 are used to supply water to the auxiliary washing cylinder assemblies 3 simultaneously, thereby being able to shorten the water inlet time of the auxiliary washing cylinder assemblies 3 and improve the laundry efficiency of the laundry treatment device.

[0087] Specifically, before water is supplied to the auxiliary washing drum assembly 3, water is first supplied to the idle main washing drum assembly 2 through the water inlet pipeline 11, so that a certain amount of water is stored in the idle main washing drum assembly 2. Then, when the auxiliary washing drum assembly 3 is being filled with water, while the water inlet pipeline 11 supplies water to the auxiliary washing drum assembly 3, the on-off valve on the inter-drum connecting pipe 4 is opened to drain the water in the idle main washing drum assembly 2 into the auxiliary washing drum assembly 3, thereby accelerating the water inlet speed of the auxiliary washing drum assembly 3 and quickly reaching the preset value of the water volume in the auxiliary washing drum assembly 3.

[0088] In this embodiment, when the water inlet pipeline 11 supplies water to the auxiliary washing drum assembly 3, it is only connected to the water inlet branch pipe 12 corresponding to the auxiliary washing drum assembly 3.

[0089] Preferably, in this embodiment, when the main washing drum assembly 2 drains water, the on-off valve on the inter-drum connecting pipe 4 between the idle auxiliary washing drum assembly 3 and the main washing drum assembly 2 can be opened while the drain valve corresponding to the main washing drum assembly 2 is opened, and part of the washing water is discharged into the idle auxiliary washing drum assembly 3.

[0090] In this embodiment, the clothing treatment device is installed on a bearing surface such as a cabinet or a wall, and is a wall-mounted clothing treatment device. Preferably, the cabinet 1 of the wall-mounted clothing treatment device is installed on the wall through expansion bolts.

[0091] Embodiment Two

[0092] The present invention also provides a control method for the clothing treatment device in the above Embodiment One.

[0093] As Figure 4 shown, the control method of the clothing treatment device includes the following steps:

[0094] When the main washing drum assembly 2 drains water, obtain the state of the auxiliary washing drum assembly 3;

[0095] If there is an auxiliary washing drum assembly 3 without a washing program, then, when the drain valve corresponding to the main washing drum assembly 2 is opened, the on-off valve between the auxiliary washing drum assembly 3 without a washing program and the main washing drum assembly 2 is opened simultaneously.

[0096] In this embodiment, the "auxiliary washing drum assembly 3 without a washing program" refers to the auxiliary washing drum assembly 3 that has not executed a washing program, that is, the idle auxiliary washing drum assembly 3.

[0097] Preferably, in this embodiment, when the main washing cylinder assembly 2 drains water into the idle auxiliary washing cylinder assembly 3, the drain valve corresponding to the auxiliary washing cylinder assembly 3 is closed, which can prevent the washing water discharged from the auxiliary washing cylinder assembly 3 from occupying the drain pipeline 13, thereby affecting the drainage speed of the main washing cylinder assembly 2 into the drain pipeline 13.

[0098] Preferably, in this embodiment, the maximum flow rate of the drain pipeline 13 and the flow rate of the drain pipeline 13 when the main washing cylinder assembly 2 drains water alone are obtained. When the main washing cylinder assembly 2 drains water, the drain valve corresponding to the auxiliary washing cylinder assembly 3 is adjusted to make the flow rate of the drain pipeline 13 close to the maximum flow rate.

[0099] Preferably, in this embodiment, a detection module for detecting the flow rate in the drain branch pipe 14 corresponding to the main washing cylinder assembly 2 is provided on the drain branch pipe 14 corresponding to the main washing cylinder assembly 2, for detecting the flow rate of the drain branch pipe 14 corresponding to the main washing cylinder assembly 2 in real time when the main washing cylinder assembly 2 drains water.

[0100] In this embodiment, during the drainage process of the main washing cylinder assembly 2, the opening degree of the drain valve corresponding to the idle auxiliary washing cylinder assembly 3 is gradually increased. When the flow rate measured by the detection module starts to decrease, the adjustment of the opening degree of the drain valve corresponding to the idle auxiliary washing cylinder assembly 3 is stopped until the main washing cylinder assembly 2 finishes draining water.

[0101] More preferably, in this embodiment, a first detection module is provided on the drain branch pipe 14 corresponding to the main washing cylinder assembly 2, and a second detection module is provided on the drain pipeline 13. During the drainage process of the main washing cylinder assembly 2, the opening degree of the drain valve corresponding to the idle auxiliary washing cylinder assembly 3 is gradually increased. When the flow rate of the drain branch pipe 14 corresponding to the main washing cylinder assembly 2 starts to decrease, and / or when the flow rate of the drain pipeline 13 reaches the maximum flow rate, the adjustment of the opening degree of the drain valve corresponding to the idle auxiliary washing cylinder assembly 3 is stopped until the main washing cylinder assembly 2 finishes draining water.

[0102] After the main washing cylinder assembly 2 finishes draining water, the idle auxiliary washing cylinder assembly 3 is connected to the drain pipeline 13, and the washing water temporarily stored in the idle auxiliary washing cylinder assembly 3 is drained.

[0103] As Figure 5 shown, in this embodiment, during the process of the auxiliary washing cylinder assembly 3 executing the washing program, if there is a subsequent water inlet requirement, and at the same time, the main washing cylinder assembly 2 is idle, then, before the auxiliary washing cylinder assembly 3 intakes water, water is first supplied to the main washing cylinder assembly 2;

[0104] When the auxiliary washing cylinder assembly 3 intakes water, the main washing cylinder assembly 2 and the water inlet pipeline 11 are used to supply water to the auxiliary washing cylinder assembly 3 simultaneously;

[0105] When the main washing drum assembly 2 is executing a washing program, when the auxiliary washing drum assembly 3 is being filled with water, only the water supply pipe 11 is used to supply water to the auxiliary washing drum assembly 3.

[0106] Preferably, the water intake volume of the auxiliary washing drum assembly 3 is divided into two parts. The first part is introduced into the main washing drum assembly 2 before the water intake node of the auxiliary washing drum assembly 3, and the second part is introduced into the auxiliary washing drum assembly 3 at the water intake node of the auxiliary washing drum assembly 3. When the second part is introduced, the water in the main washing drum assembly 2 is simultaneously introduced into the auxiliary washing drum assembly 3;

[0107] The ratio of the volume of the first part of the water intake to the volume of the second part of the water intake is equal to the ratio of the flow rate of water supplied from the main washing drum assembly 2 to the auxiliary washing drum assembly 3 to the flow rate of water supplied from the water supply pipe 11 to the auxiliary washing drum assembly 3.

[0108] Through the above settings, the water intake efficiency of the auxiliary washing drum assembly 3 can be increased, the water intake time of the auxiliary washing drum assembly 3 can be shortened, and thus, the laundry efficiency of the auxiliary washing drum assembly 3 can be increased.

[0109] Embodiment III

[0110] In this embodiment, the auxiliary washing drum assembly 3 includes a first auxiliary washing drum assembly 3 and a second auxiliary washing drum assembly 3. The first auxiliary washing drum assembly 3 is arranged above the main washing drum assembly 2, and the second auxiliary washing drum assembly 3 is arranged below the main washing drum assembly 2. Inter-cylinder connecting pipes 4 are respectively arranged between the first auxiliary washing drum assembly 3 and the second auxiliary washing drum assembly 3 and the main washing drum assembly 2.

[0111] In an embodiment of the present invention, a control method for the above-mentioned laundry treatment device is also provided.

[0112] As Figure 6 shown, the control method of the laundry treatment device includes the following steps:

[0113] S1: During the process of the main washing drum assembly 2 executing a washing program, it is judged whether there is still a water intake requirement in the subsequent process. If the judgment result is "yes", then S2 is executed;

[0114] S2: Obtain the state of the first auxiliary washing drum assembly 3. If there is a first auxiliary washing drum assembly 3 without a washing program, then, before the main washing drum assembly 2 is filled with water, water is introduced into the first auxiliary washing drum assembly 3 without a washing program;

[0115] S3: When the main washing drum assembly 2 is filled with water, the first auxiliary washing drum assembly 3 and the water supply pipe 11 are used to supply water to the main washing drum assembly 2 simultaneously.

[0116] In this embodiment, the "first auxiliary washing cylinder assembly 3 without a washing program" refers to the first auxiliary washing cylinder assembly 3 that has not executed a washing program, that is, the idle first auxiliary washing cylinder assembly 3.

[0117] In this embodiment, by providing the main washing cylinder assembly 2 and the first auxiliary washing cylinder assembly 3, it is possible to achieve classified washing of different clothes and avoid cross-infection. By providing an inter-cylinder connecting pipe 4 between the first auxiliary washing cylinder assembly 3 and the main washing cylinder assembly 2, when the first auxiliary washing cylinder assembly 3 is not executing a washing program, it can be used to store a certain amount of washing water. When the main washing cylinder assembly 2 is filling with water, the first auxiliary washing cylinder assembly 3 and the water inlet pipeline 11 are used to supply water to the main washing cylinder assembly 2 simultaneously, thereby shortening the water inlet time of the main washing cylinder assembly 2 and improving the laundry efficiency of the clothing processing equipment.

[0118] In this embodiment, there can be one or two "first auxiliary washing cylinder assemblies 3 without a washing program". If both of the two first auxiliary washing cylinder assemblies 3 are idle, then before filling the main washing cylinder assembly 2 with water, fill the two idle first auxiliary washing cylinder assemblies 3 with water, and use the two first auxiliary washing cylinder assemblies 3 to store the water for filling the main washing cylinder assembly 2. When filling the main washing cylinder assembly 2 with water, simultaneously use the two first auxiliary washing cylinder assemblies 3 and the water inlet pipeline 11 to fill the main washing cylinder assembly 2 with water, which can further shorten the water inlet time of the main washing cylinder assembly 2, reduce the waiting time of the main washing cylinder assembly 2, and thus improve the washing efficiency.

[0119] Preferably, in this embodiment, when only one first auxiliary washing cylinder assembly 3 is idle, it is equivalent to dividing the water inlet of the main washing cylinder assembly 2 into two parts. One part is pre-stored by the first auxiliary washing cylinder assembly 3, and the other part is input by the water inlet pipeline 11.

[0120] Specifically, when the main washing cylinder assembly 2 is running a washing program before the water inlet node, water is filled into the idle first auxiliary washing cylinder assembly 3 so that the idle first auxiliary washing cylinder assembly 3 stores a part of the water. When the main washing cylinder assembly 2 is filling with water, no more water is supplied to the idle first auxiliary washing cylinder assembly 3, and the water inlet pipeline 11 only supplies water to the main washing cylinder assembly 2. At the same time, the on-off valve on the inter-cylinder connecting pipe 4 is opened to allow the water stored in the first auxiliary washing cylinder assembly 3 to enter the main washing cylinder assembly 2.

[0121] Preferably, the water inlet time of the first auxiliary washing cylinder assembly 3 into the main washing cylinder assembly 2 is the same as the water inlet time of the water inlet pipeline 11 into the main washing cylinder assembly 2.

[0122] When both of the two first auxiliary washing cylinder assemblies 3 are idle, it is equivalent to dividing the water inlet of the main washing cylinder assembly 2 into three parts. Two of the water inlets are stored separately by the two first auxiliary washing cylinder assemblies 3, and the third part is fed into the main washing cylinder assembly 2 through the water inlet pipeline 11. When the main washing cylinder assembly 2 runs the washing program before the water inlet node, it first feeds the two parts of water into the two first auxiliary washing cylinder assemblies 3 for storage. When the main washing cylinder assembly 2 takes in water, it simultaneously supplies water to the main washing cylinder assembly 2 by using the two cylinder assemblies and the water inlet pipeline 11. The duration of water inlet from the first auxiliary washing cylinder assembly 3 into the main washing cylinder assembly 2 is the same as the duration of water inlet from the water inlet pipeline 11 into the main washing cylinder assembly 2.

[0123] When the clothing treatment device leaves the factory, it obtains the water supply flow rate from the first auxiliary washing cylinder assembly 3 to the main washing cylinder assembly 2 and the water supply flow rate from the water inlet pipeline 11 to the main washing cylinder assembly 2.

[0124] When the clothing treatment device is in operation, it obtains in advance the water intake required by the main washing cylinder assembly 2 before water inlet.

[0125] When only one of the two first auxiliary washing cylinder assemblies 3 is idle, the water intake of the main washing cylinder assembly 2 is divided into two parts. The first part is fed into the idle first auxiliary washing cylinder assembly 3 before the water inlet node of the main washing cylinder assembly 2, and the second part is fed into the main washing cylinder assembly 2 at the water inlet node of the main washing cylinder assembly 2. When the second part is fed in, the water in the idle first auxiliary washing cylinder assembly 3 is simultaneously fed into the main washing cylinder assembly 2.

[0126] In this embodiment, the ratio of the volume of the first part of water inlet to the volume of the second part of water inlet is equal to the ratio of the water supply flow rate from the first auxiliary washing cylinder assembly 3 to the main washing cylinder assembly 2 to the water supply flow rate from the water inlet pipeline 11 to the main washing cylinder assembly 2.

[0127] In this embodiment, when the first part of water inlet is greater than the capacity of the first auxiliary washing cylinder assembly 3, before the water inlet node of the main washing cylinder assembly 2, the first auxiliary washing cylinder assembly 3 is filled with water, and at the water inlet node of the main washing cylinder assembly 2, the remaining water inlet is directly fed into the main washing cylinder assembly 2 through the water inlet pipeline 11.

[0128] When both of the two first auxiliary washing cylinder assemblies 3 are idle, the water intake of the main washing cylinder assembly 2 is divided into three parts. Before the water inlet node of the main washing cylinder assembly 2, the first part of water inlet and the second part of water inlet are respectively fed into the two first auxiliary washing cylinder assemblies 3, and the third part of water inlet is fed into the main washing cylinder assembly 2 through the water inlet pipeline 11 at the water inlet node.

[0129] In this embodiment, the ratio among the first part of water inlet, the second part of water inlet, and the third part of water inlet is equal to the ratio of the water supply flow rates from the first first auxiliary washing cylinder assembly 3, the second first auxiliary washing cylinder assembly 3, and the water inlet pipeline 11 to the main washing cylinder assembly 2.

[0130] In this embodiment, when the first portion of the incoming water is greater than the capacity of the first first auxiliary washing cylinder assembly 3, and / or when the second portion of the incoming water is greater than the capacity of the second first auxiliary washing cylinder assembly 3, before the water inlet node of the main washing cylinder assembly 2, the first first auxiliary washing cylinder assembly 3 and / or the second first auxiliary washing cylinder assembly 3 are filled with water, and at the water inlet node of the main washing cylinder assembly 2, the remaining incoming water is directly introduced into the main washing cylinder assembly 2 through the water inlet pipeline 11.

[0131] In this embodiment, the water inlet pipeline 11 can supply water to the two idle first auxiliary washing cylinder assemblies 3 simultaneously, or can supply water to the two idle cylinder assemblies in sequence.

[0132] Preferably, in this embodiment, flow meters are respectively arranged on the three water inlet branch pipes 12 for detecting the water inflow, and the water inflows of the two first auxiliary washing cylinder assemblies 3 and the main washing cylinder assembly 2 are precisely controlled through the flow meters. The flow meters are communicatively connected to the control unit.

[0133] In this embodiment, the washing program includes a washing stage and a rinsing stage.

[0134] The control method of the clothing treatment device is specifically as follows:

[0135] When the washing stage of the main washing cylinder assembly 2 runs to drainage or dehydration, water is supplied to the first auxiliary washing cylinder assembly 3 without a washing program.

[0136] When the main washing cylinder assembly 2 starts to enter the rinsing stage, the water supply to the first auxiliary washing cylinder assembly 3 without a washing program is stopped, and the first auxiliary washing cylinder assembly 3 and the water inlet pipeline 11 are used to supply water to the main washing cylinder assembly 2 simultaneously.

[0137] Specifically, the time point of "supplying water to the first auxiliary washing cylinder assembly 3 without a washing program" can be set according to the time required to fill the two first auxiliary washing cylinder assemblies 3 with water, and the time required to fill the two first auxiliary washing cylinder assemblies 3 with water is less than or equal to the remaining time of the washing stage when "supplying water to the first auxiliary washing cylinder assembly 3 without a washing program".

[0138] In this embodiment, the water inflow of the main washing cylinder assembly 2 can be determined by the amount of clothing in the main washing cylinder assembly 2.

[0139] Preferably, in this embodiment, when the dosing module doses the washing additive into the main washing cylinder assembly 2, the washing additive is first dosed into the first auxiliary washing cylinder assembly 3 without a washing program.

[0140] The first auxiliary washing cylinder assembly 3 operates to dissolve the washing additive and then introduces it into the main washing cylinder assembly 2.

[0141] Specifically, the control method of the clothing treatment device further includes:

[0142] S1.0: When it is necessary to put washing additives into the main washing cylinder assembly 2, obtain the status of the first auxiliary washing cylinder assembly 3. When there is an idle first auxiliary washing cylinder assembly 3, execute S2.0; when there is no idle first auxiliary washing cylinder assembly 3, execute S3.0;

[0143] S2.0: Put a preset amount of washing additives into an idle first auxiliary washing cylinder assembly 3;

[0144] S2.1: The first auxiliary washing cylinder assembly 3 operates to dissolve the washing additives. Then, the solution of the washing additives is introduced into the main washing cylinder assembly 2;

[0145] S3.0: Put a preset amount of washing additives into the main washing cylinder assembly 2.

[0146] In this embodiment, the dosage of the washing additives can be determined according to the amount of clothes and the degree of dirt in the main washing cylinder assembly 2.

[0147] Preferably, in this embodiment, after the solution of the washing additives in the first auxiliary washing cylinder assembly 3 is introduced into the main washing cylinder assembly 2, the first auxiliary washing cylinder assembly 3 is filled with water, so that the water flushes the first auxiliary washing cylinder assembly 3 and is introduced into the main washing cylinder assembly 2 to ensure the dosing accuracy.

[0148] When the main washing cylinder assembly 2 drains water, obtain the status of the second auxiliary washing cylinder assembly 3;

[0149] If there is a second auxiliary washing cylinder assembly 3 without a washing program, then when the drain valve corresponding to the main washing cylinder assembly 2 is opened, the on-off valve between the second auxiliary washing cylinder assembly 3 without a washing program and the main washing cylinder assembly 2 is opened simultaneously.
