Description

Technical Field

[0001] The present disclosure relates to the field of clothing treatment, and in particular, to a rinsing method for a clothing treatment device and a clothing treatment device. Background Art

[0002] In the prior art, the detergent residue in a drum washing machine is an important problem that plagues many users at present. Therefore, eliminating the detergent residue in the rinsing stage is of great significance for healthy washing. The traditional washing method drains water from the bottom. The foam generated during rinsing basically floats on the water surface. After the rinsing water is discharged by the drain pump, the foam remains in positions such as the door seal and the door glass due to the surface tension. Most of the current solutions adopt the method of flushing the door glass with clean water. However, since the traditional bottom drainage method is still maintained, the foam floating on the surface and the detergent in it cannot be discharged with the water, and they accumulate at the lower part of the door glass and the folds of the door seal. Not only will they return to the clothes during rinsing and contaminate the clothes, but also long-term accumulation will cause problems such as mildew. Summary of the Invention

[0003] The present disclosure aims to at least solve one of the technical problems existing in the prior art. To this end, an object of the present disclosure is to provide a rinsing method for a clothing treatment device, which can effectively reduce the amount of detergent residue on the surface of the clothes after rinsing, make the clothing washing healthier, and improve the user experience.

[0004] The present disclosure provides a rinsing method for a clothing treatment device. The clothing treatment device includes a barrel assembly, a drainage assembly, and a door seal assembly. A first drainage channel connects the drainage assembly and the barrel assembly, and a second drainage channel connects the drainage assembly and the door seal assembly;

[0005] The method includes: running a first rinsing mode, closing the first drainage channel and opening the second drainage channel.

[0006] According to the rinsing method of the present disclosure, by controlling the clothing treatment device to run the first rinsing mode during rinsing, the rinsing water flows out of the barrel assembly from the drainage opening at the door seal. Since a large amount of foam and detergent in it accumulate at the door seal during rinsing, a large amount of detergent components are drained away from the first drainage channel, reducing the detergent content in the rinsing water in the barrel assembly. And the detergent in this part of the water will no longer reattach to the clothes with the water flow, which can effectively reduce the amount of detergent residue on the surface of the clothes after rinsing, make the clothing washing healthier, and improve the user experience.

[0007] Optionally, the method further includes: running a second rinsing mode, opening the first drainage channel and the second drainage channel.

[0008] Optionally, the laundry treatment device further includes a first valve assembly disposed in the second drainage channel, and the first valve assembly is configured to conduct or close the second drainage channel; closing the first drainage channel includes closing the first valve assembly.

[0009] Optionally, before running the first rinsing mode, the method includes: obtaining the water level of the tub assembly; determining that the water level is higher than a first preset water level, and controlling the laundry treatment device to select the first rinsing mode, where the first preset water level is higher than the upper surface of the door seal.

[0010] Optionally, the method includes: determining that the water level is lower than or equal to a second preset water level, and closing the first drainage channel and the second drainage channel, where the second preset water level is lower than the first preset water level.

[0011] Optionally, before running the second rinsing mode, the method includes: determining that the water level is lower than a third preset water level, and controlling the laundry treatment device to fill water into the tub assembly, where the third preset water level is lower than the first preset water level.

[0012] Optionally, running the first rinsing mode further includes: controlling the tub assembly to rotate or filling water into the tub assembly.

[0013] Optionally, the method includes: recording the number of times of executing the first rinsing mode; determining that the number of times is greater than or equal to a preset number of times, and controlling the laundry treatment device to run in the second rinsing mode until the rinsing process ends.

[0014] The present disclosure also provides a laundry treatment device, characterized in that the laundry treatment device includes a tub assembly, a drainage assembly, a door seal assembly, a first drainage channel connecting the drainage assembly and the tub assembly, and a second drainage channel connecting the drainage assembly and the door seal assembly; the control unit is configured to control the laundry treatment device to run the first rinsing mode, close the first drainage channel and conduct the second drainage channel.

[0015] The present disclosure also provides a laundry treatment device, including a processor and a memory, and the processor executes the steps of any of the above methods by calling a program or instruction stored in the memory.

[0016] The technical solution provided by the present disclosure has the following advantages compared with the prior art:

[0017] According to the rinsing method of the present disclosure, during the rinsing process, the laundry treatment device is controlled to operate in the first rinsing mode, so that the rinsing water flows out of the barrel assembly from the drain outlet at the door seal. Since a large amount of foam and detergent therein generated during rinsing accumulate at the door seal, a large amount of detergent components are drained away through the first drainage channel, reducing the detergent content in the rinsing water in the barrel assembly. Moreover, the detergent in this part of the water will not reattach to the laundry with the water flow again, which can effectively reduce the detergent residue on the surface of the laundry after rinsing, making the laundry washing healthier and improving the user experience. In addition, the present disclosure further includes a second rinsing mode, which can meet the requirement of discharging a large amount of rinsing water, thereby ensuring the rinsing effect.

[0023] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0025] The following will exemplarily illustrate the rinsing method of the laundry treatment device and the laundry treatment device provided by the embodiments of the present disclosure with reference to the accompanying drawings.

[0026] Exemplarily, Figure 1The structural diagram of a laundry treatment device provided by an embodiment of the present disclosure is referred to Figure 1 , the laundry treatment device 1 of the present disclosure is a drum washing machine or a washing and drying integrated machine. The laundry treatment device 1 includes a cabinet (not shown), a tub assembly 101, a door seal assembly 103, and a drainage assembly 102. Among them, the cabinet includes a front door, an upper cover, a lower cover, and side plates, defining the internal space of the laundry treatment device; the tub assembly 101 is disposed in the cabinet and is connected to the cabinet through a shock absorption device. A laundry treatment cavity for placing laundry is formed in the tub assembly 101; in some embodiments, the tub assembly 101 includes an outer tub for containing washing water and an inner tub rotatably disposed in the outer tub. The inner tub can be a structure with holes in the side wall or a structure without drainage holes in the side wall. The laundry treatment cavity is formed in the inner tub, and the laundry treatment cavity communicates with a laundry inlet disposed on the front door; in other embodiments, the tub assembly 101 is a single tub structure without drainage holes in the side wall, and a laundry treatment cavity is formed in the single tub structure; a first drainage port is disposed on the tub assembly 101 for draining the washing water in the tub assembly 101. Preferably, the first drainage port is disposed in the lower half of the tub assembly 101 in the height direction.

[0027] The door seal assembly 103 is disposed between the front door and the tub assembly 101 for connecting the front door and the tub assembly 101. The door seal assembly 103 can be a structure made of a flexible material or a water baffle structure. A spray port (not shown) and a second drainage port (not shown) are disposed on the door seal assembly 101. The spray port is disposed in the upper half of the door seal assembly 103 in the height direction. The spray port is connected to an external water source for spraying and flushing the door glass or the door seal assembly 103 to remove foam or detergent on the door glass or the door seal assembly 103; the second drainage port is disposed in the lower half of the door seal assembly 103, preferably at the lowest point of the door seal assembly 103 in the height direction, for draining the water near the door seal assembly 103.

[0028] The drainage assembly 102 is used to drain the washing water from the laundry treating apparatus 1. The drainage assembly 102 may be a functional component such as a drainage valve, a drainage pump, etc. The drainage assembly 102 is connected to the first drainage port of the tub assembly 101 through the first drainage channel 104. The washing water in the tub assembly 101 flows into the drainage assembly through the first drainage channel 104 and is finally drained from the laundry treating apparatus 1. In some embodiments, a first valve assembly is provided in the first drainage channel 104. The first valve assembly may be provided at any position of the first drainage port, the drainage assembly, and the connecting pipe therebetween. The first valve assembly is used to control the opening or closing of the first drainage channel 104. When the first valve assembly is closed, the washing water in the tub assembly 101 cannot be drained through the first drainage channel 104. In the embodiments of the present disclosure, the drainage assembly 102 is connected to the second drainage port on the door seal assembly 103 through the second drainage channel 105. When the drainage assembly 102 operates, the washing water at the door seal assembly 103 flows into the drainage assembly through the second drainage channel 105 and is finally drained from the laundry treating apparatus 1.

[0029] In the prior art, the detergent residue in the drum washing machine is an important problem that plagues many users at present. Therefore, it is of great significance to eliminate the detergent residue during the rinsing stage for healthy washing. The traditional washing method drains water from the bottom. The foam generated during rinsing basically floats on the water surface. After the rinsing water is drained by the drainage pump, the foam remains at positions such as the door seal and the door glass due to the surface tension. Most of the current solutions adopt the method of flushing the door glass with clean water. However, since the traditional bottom drainage method is still maintained, the foam floating on the surface and the detergent in it cannot be drained with the water, and accumulates at the lower part of the door glass and the folds of the door seal. This not only returns to the clothes to contaminate the clothes during rinsing, but also causes problems such as mildew after long-term accumulation.

[0030] Exemplarily, Figure 2 is a schematic flow chart of a rinsing method provided by an embodiment of the present disclosure. Refer to Figure 2 and the rinsing method may include the following steps:

[0031] S100. Run the first rinsing mode, close the first drainage channel, and conduct the second drainage channel.

[0032] Here, the laundry treating apparatus 1 according to the embodiments of the present disclosure has washing, rinsing, dewatering, and / or drying processes, and the rinsing process includes a first rinsing mode and a second rinsing mode. The applicant has found that in the conventional rinsing stage, rinsing the relatively high content of washing agent on the surface of the laundry with a relatively high water level will generate a large amount of foam, and as the washing tub rotates during the rinsing process, these foams will continuously move towards the door seal assembly 103 and accumulate at the door seal assembly 103 and the door glass. In order to remove the foam and washing agent accumulated at the door seal assembly 103 and the door glass, in the early stage of rinsing in the embodiments of the present disclosure, that is, in the stage where the rinsing water contains a relatively high amount of washing agent, the first rinsing mode is operated. In this rinsing mode, the first drainage channel is closed and the second drainage channel is opened. In some embodiments, the laundry treating apparatus has a drainage assembly 102, which is connected to both the first drainage channel and the second drainage channel. In this embodiment, the first valve assembly on the first drainage channel is controlled to be closed. Thus, when the drainage assembly 102 operates, the first drainage channel is closed, and the washing agent in the rinsing water cannot be discharged through the first drainage port of the tub assembly 101, and can only be discharged through the second drainage port on the door seal assembly 103. The water flow is unidirectional from the tub to the first drainage port, avoiding the washing agent in the rinsing water from flowing back to the surface of the laundry and adhering again; at the same time, since the drainage capacity of the first drainage channel is relatively strong and the drainage capacity of the second drainage channel is weaker than that of the first drainage channel, draining through the first drainage channel can prevent the rinsing water level in the tub from dropping rapidly during rinsing, resulting in a decline in the rinsing effect. In other embodiments, the drainage assembly 102 includes at least two drainage components, which are respectively connected to the first drainage channel and the second drainage channel. At this time, the first rinsing mode includes closing the drainage component connected to the first drainage channel and opening the drainage component connected to the second drainage channel, so that the water flow is unidirectional from the tub to the first drainage port, and draining through the first drainage channel can prevent the rinsing water level in the tub from dropping rapidly during rinsing, resulting in a decline in the rinsing effect.

[0033] Thus, according to the rinsing method of the present disclosure, during the rinsing process, by controlling the laundry treating apparatus to operate the first rinsing mode, the rinsing water flow flows out of the washing tub through the drainage port at the door seal. Since a large amount of foam and detergent therein generated during rinsing accumulate at the door seal, a large amount of detergent components are drained away through the first drainage channel, reducing the detergent content in the rinsing water in the washing tub, and the detergent in this part of the water will not reattach to the laundry along with the water flow again, which can effectively reduce the detergent residue on the surface of the laundry after rinsing, making the laundry washing healthier and improving the user experience.

[0034] In some embodiments, the rinsing method further includes:

[0035] S200. Operating the second rinsing mode to conduct the first drainage channel and the second drainage channel.

[0036] Here, due to the limited capacity of the rinsing water discharge in the first rinsing mode, after running the first rinsing mode multiple times, the second rinsing mode is run while the first drainage channel and the second drainage channel are turned on, thereby meeting the demand for discharging a large amount of rinsing water and ensuring the rinsing effect.

[0037] In some embodiments, before running the first rinsing mode, the method includes: obtaining the water level of the tub assembly 101; determining that the water level is higher than a first preset water level, and controlling the laundry treatment device to select the first rinsing mode, wherein the first preset water level is higher than the upper surface of the door seal assembly 103.

[0038] Here, a conventional rinsing operation injects rinsing water at a certain water level into the laundry treatment chamber, and usually a sensing structure such as a water level sensor is used to obtain the water level height of the injected rinsing water. In the embodiments of the present disclosure, since the purpose of the first rinsing mode is to discharge the foam or washing agent accumulated at the door seal assembly 103, the condition for executing the first rinsing mode is set to be that the water level is higher than the first preset water level on the upper surface of the door seal assembly 103. Thus, when the second drainage channel is turned on for drainage, the rinsing water at the door seal assembly 103 can flow into the second drainage channel through the second drainage port of the door seal assembly 103, thereby avoiding the situation where the rinsing water cannot be discharged from the second drainage channel due to insufficient water level. In some embodiments, executing the first rinsing mode can be by the user inputting corresponding instructions through a mobile phone APP, a control panel, etc., or the laundry treatment device can select and execute it based on preset conditions. No matter which way, the optimal embodiment is that the water level in the laundry treatment chamber needs to be higher than the position of the upper surface of the door seal assembly 103 so as to ensure that the accumulated washing agent is smoothly discharged.

[0039] In some embodiments, the method includes: determining that the water level is lower than or equal to a second preset water level, and closing the first drainage channel and the second drainage channel, wherein the second preset water level is lower than the first preset water level.

[0040] Here, a conventional rinsing operation requires a certain water level. In the first rinsing mode, since the second drainage channel being turned on will cause the water level in the tub assembly to continuously drop, and a lower water level will result in a poor rinsing effect. Therefore, in the embodiments of the present disclosure, a second preset water level lower than the first preset water level is set as the minimum water level required for the rinsing operation. When the water level in the tub assembly of the laundry treatment device is lower than the second preset water level, the first drainage channel and the second drainage channel are closed simultaneously. At this time, the rinsing water no longer flows out of the tub assembly, and the rinsing water level remaining in the tub assembly is maintained at the minimum water level that meets the requirements of the rinsing operation, thereby ensuring the rinsing effect.

[0041] In some embodiments, before running the second rinsing mode, the method includes: determining that the water level is lower than a third preset water level, and controlling the laundry treatment device to fill water into the tub assembly, where the third preset water level is lower than the first preset water level.

[0042] Here, in order to avoid the problem that in the first rinsing mode, the water level in the tub assembly continuously drops due to the opening of the second drainage channel, resulting in poor rinsing effect, in the embodiments of the present disclosure, a third preset water level lower than the first preset water level is set as the water level for replenishing water into the tub assembly during the rinsing operation. In the first rinsing mode, the rinsing water in the tub assembly is discharged from the tub assembly through the second drainage channel, so that the rinsing water level in the tub assembly is lower than the surface of the door seal assembly. At this time, the first rinsing mode can be stopped, and the rinsing water level can be increased by replenishing water into the tub assembly, and the first rinsing mode can be continued after the water level is higher than the first preset water level again. Among them, the way of replenishing water can be to replenish water between the inner and outer tubs through the dosing component, or to directly inject rinsing water into the laundry treatment chamber through the water replenishing channel or directly spray the rinsed load. The present disclosure does not make further limitations on this.

[0043] In some embodiments, running the first rinsing mode further includes: controlling the tub assembly to rotate, or filling water into the tub assembly.

[0044] Here, the applicant has found through research that during the rinsing operation, controlling the rotation of the tub assembly to drive the movement and beating of the load can better remove the washing components on the surface of the load, and the washing components in the water will move towards the direction of the door seal assembly under the fluctuation of the water flow. At this time, more washing agents will be discharged from the second drainage channel along with the water flow, thereby greatly reducing the detergent residue on the surface of the load. In addition, while running the first rinsing mode, spraying water from the spray channel towards the direction of the door seal assembly can give the water flow a downward force in the area of the door seal assembly, thereby making it easier to drive the washing agents in the rinsing water to be discharged through the second drainage channel. The above means can effectively improve the discharge ability of the detergent residue and eliminate the foam generated at the door seal assembly, improving the user experience.

[0045] In some embodiments, the method includes: recording the number of times of executing the first rinsing mode; determining that the number of times is greater than or equal to a preset number of times, and controlling the laundry treatment device to run in the second rinsing mode until the rinsing process ends.

[0046] Here, when the first rinsing mode is executed for a preset number of times, it can be considered that a relatively large proportion of the washing preparation in the rinsing water has been discharged through the second drainage channel. In order to save the duration of the rinsing operation, in the embodiments of the present disclosure, it is set that when the number of runs of the first rinsing mode is greater than or equal to the preset number, the second rinsing mode is executed, and all the rinsing water is discharged from the tub assembly through the first drainage channel, or the operation of feeding water into the tub assembly and draining water through the first drainage channel is performed simultaneously. Thus, through the update of a large amount of rinsing water, the residual amount of the washing preparation is further reduced, and the rinsing effect is improved. The specific preset number can be determined based on actual product design or experiments, and the embodiments of the present disclosure do not make specific limitations thereon.
