Description

Technical Field

[0001] The present application relates to the field of clothing processing, and in particular to a drum washing machine and a control method, device and storage medium thereof. Background Art

[0002] In the related art, due to structural reasons, the inner drum and outer barrel of a drum washing machine are interconnected. After long-term use, a large amount of lint, bacteria, mildew and other dirt will accumulate between the inner drum and the outer barrel. During washing, the dirt between the inner drum and the outer barrel will cross-contaminate the clothes in the inner drum, resulting in unclean washing of the clothes, affecting the user experience.

[0003] As users have higher and higher demands for healthy washing, drum washing machines with no holes in the inner drum have emerged. Drum washing machines with no holes in the inner drum can isolate the clothes in the inner drum, so that they are only washed inside the inner drum, and there is no water in the outer drum or the water in the outer drum will not flow back into the inner drum, thus avoiding the dirt between the inner and outer drums from contaminating the clothes.

[0004] However, in order to prevent the water in the outer drum from entering the inner drum and contaminating the clothes in the inner drum, the water level in the inner drum of a drum washing machine without a hole in the inner drum cannot be higher than the front edge of the inner drum (such as Figure 1 If the water level in the inner drum 1 is higher than the inner drum front edge 1A, a lot of water will gradually accumulate in the outer drum 2 and will gradually flow back to the inner drum 1, contaminating the clothes in the inner drum 1). Due to the small amount of rinsing water, under the same number of rinsing times, the rinsing performance of the drum washing machine with a non-porous inner drum will be worse than that of a conventional washing machine. Summary of the invention

[0005] In view of this, an embodiment of the present application provides a drum washing machine and a control method, device and storage medium thereof, aiming to effectively improve the clothing rinsing performance of a drum washing machine with a non-porous inner drum.

[0006] The technical solution of the embodiment of the present application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides a method for controlling a drum washing machine, comprising:

[0008] During the rinsing water inlet process, if it is determined that the water level of the outer tub meets the preset conditions, rinsing is started;

[0009] During the rinsing process, control the water inlet to the inner drum and the water outlet to the outer drum;

[0010] Wherein, the preset conditions at least include: the water level of the outer tub is greater than the rated minimum water level; during the rinsing process, the water level of the outer tub is greater than the rated minimum water level and less than the rated maximum water level.

[0011] In some embodiments, during the rinsing process, controlling water inflow into the inner drum and water out of the outer drum includes:

[0012] During the rinsing process, the inner drum is controlled to continuously inlet water, and the outer drum is controlled to continuously drain water or intermittently drain water.

[0013] In some embodiments, during the rinsing process, controlling water inflow into the inner drum and water out of the outer drum includes:

[0014] During the rinsing process, the inner drum is controlled to intermittently supply water, and the outer drum is controlled to drain water continuously or intermittently.

[0015] In some embodiments, determining that the water level of the outer barrel meets a preset condition includes:

[0016] If the load of the clothes is a large load, determining that the water level of the outer tub is greater than or equal to the set water level and less than the rated maximum water level;

[0017] If the load of the clothes is a small load, it is determined that the water level of the outer tub is greater than the rated minimum water level and less than the set water level.

[0018] In some embodiments, the set water level is the water level corresponding to the lower edge of the inner drum, and the rated maximum water level is the water level corresponding to the lower edge of the clothing opening.

[0019] In some embodiments, the method further comprises:

[0020] If it is determined that the number of rinses is less than the set number, the rinse cycle is performed until the number of rinses reaches the set number, and then the rinse cycle is exited.

[0021] In a second aspect, an embodiment of the present application provides a control device for a drum washing machine, comprising:

[0022] The control module is used to determine that the water level of the outer tub meets the preset conditions during the rinsing water inlet process, and then start rinsing; during the rinsing process, control the water inlet of the inner tub and the water outlet of the outer tub;

[0023] Wherein, the preset conditions at least include: the water level of the outer tub is greater than the rated minimum water level; during the rinsing process, the water level of the outer tub is greater than the rated minimum water level and less than the rated maximum water level.

[0024] In a third aspect, an embodiment of the present application provides a drum washing machine, comprising: an outer drum and an inner drum rotating relative to the outer drum, the drum washing machine also comprising: a processor and a memory for storing a computer program that can be run on the processor, wherein the processor, when running the computer program, executes the steps of the method described in the first aspect of the embodiment of the present application.

[0025] In some embodiments, a closable drainage hole is provided on the wall of the inner cylinder.

[0026] In a fourth aspect, an embodiment of the present application further provides a storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the method described in the first aspect of the embodiment of the present application are implemented.

[0027] The technical solution provided by the embodiment of the present application starts rinsing when the water level of the outer drum meets the preset conditions during the rinsing water inlet process, which can effectively prevent the water level of the outer drum from being too high, causing dirt to flow back into the inner drum and contaminate the clothes. In addition, during the rinsing process, the inner drum water inlet and the outer drum water outlet are controlled, so that the rinsed water with detergent in the inner drum gradually overflows into the outer drum and is discharged in time, and new and clean water is injected into the inner drum to rinse the clothes. In this way, under the premise of the same rinsing time and number of rinsing times, the drum washing machine with a hole-free inner drum can achieve a rinsing effect equivalent to or even better than that of an ordinary washing machine.

[0034] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0036] In the related art, drum washing machines generally adopt a structure with a perforated inner drum, that is, the inner drum and the outer drum are interconnected, and the water level in the inner drum can be judged based on the water level detected by the water level sensor corresponding to the outer drum, so as to control the washing water level or the rinsing water level to be in a reasonable range. However, after long-term use, a large amount of lint, bacteria, mildew and other dirt will accumulate between the inner drum and the outer drum. During washing, the dirt between the inner drum and the outer drum will cross-contaminate the clothes in the inner drum, resulting in unclean washing of the clothes, affecting the user experience.

[0037] Based on this, an embodiment of the present application provides a control method for a drum washing machine based on a hole-free inner drum. The drum washing machine can be a washer-dryer with a drying function or a washing machine without a drying function, and the embodiment of the present application does not limit this.

[0038] Exemplarily, the drum washing machine includes: an outer drum and an inner drum that rotates relative to the outer drum. The inner drum is a hole-free inner drum structure. It is understandable that the inner drum has a clothing opening for taking clothes in and out, and the clothing opening forms the front edge of the inner drum and can allow water to enter the inner drum. In order to facilitate the drainage of the inner drum, a closable drainage hole can be provided on the wall of the inner drum. For example, an electromagnetic switch or a centrifugal switch based on the centrifugal force of rotation can be provided at the drainage hole, and the embodiment of the present application does not limit this.

[0039] In actual applications, during the washing and / or rinsing stage, the drainage holes on the inner drum can be closed to isolate the inner drum and the outer drum to prevent the dirt between the inner drum and the outer drum from contaminating the clothes. During the drainage and dehydration stage, the drainage holes on the inner drum can be opened to drain all the residual water in the inner drum.

[0040] It is understandable that lifting ribs can be provided on the inner wall surface of the inner drum, so as to continuously lift the clothes during washing, thereby achieving washing without causing the clothes to fall and hit, so as to clean the clothes.

[0041] It should be noted that the structure of the hole-free inner cylinder in the embodiment of the present application results in a lack of communication between the inner cylinder and the outer cylinder. The traditional water level sensor can only detect the water level of the outer cylinder but cannot obtain the water level of the inner cylinder. As a result, how to achieve precise control of the water level in the inner cylinder has become a technical problem that needs to be solved urgently.

[0042] like Figure 2 As shown, the control method of the drum washing machine in the embodiment of the present application includes:

[0043] Step 201, during the rinsing water inlet process, if it is determined that the water level in the outer tub meets a preset condition, rinsing is started.

[0044] Step 202, during the rinsing process, control the water inlet into the inner drum and the water outlet from the outer drum.

[0045] In the embodiment of the present application, the preset condition at least includes: the water level in the outer tub is greater than the rated minimum water level; during the rinsing process, the water level in the outer tub is greater than the rated minimum water level and less than the rated maximum water level.

[0046] It is understandable that during the rinsing water inlet process, if it is determined that the water level of the outer drum meets the preset conditions, rinsing is started, thereby achieving the effect of controlling the water level of the inner drum based on the water level sensor of the outer drum, and effectively preventing the water level of the outer drum from being too high, causing dirt to flow back into the inner drum and contaminate the clothes. In addition, during the rinsing process, controlling the water inlet of the inner drum and the drainage of the outer drum can make the rinsed water with detergent in the inner drum gradually overflow into the outer drum and be drained away in time, while new and clean water is injected into the inner drum to rinse the clothes. In this way, under the premise of the same rinsing time and number of rinsing times, the drum washing machine with a hole-free inner drum can achieve a rinsing effect equivalent to or even better than that of an ordinary washing machine.

[0047] Exemplarily, during the rinsing process, controlling water inflow into the inner drum and water out of the outer drum includes:

[0048] During the rinsing process, the inner drum is controlled to continuously inlet water, and the outer drum is controlled to continuously drain water or intermittently drain water.

[0049] Here, during the rinsing process, the water inlet valve that guides water into the inner drum can be controlled to be continuously turned on, and the drain valve of the outer drum can be controlled to continuously drain water or to drain water intermittently based on a set start-stop ratio. It should be noted that by controlling the drain valve to drain water continuously or intermittently, during the rinsing process, while the inner drum is continuously supplied with water, the water level of the outer drum can always be greater than the rated minimum water level and less than the rated maximum water level.

[0050] It should be noted that during the rinsing process, the drainage holes on the inner drum are in a closed state, and the water after rinsing clothes in the inner drum can overflow into the outer drum through the clothing opening and be discharged in time by the drainage valve of the outer drum, thereby preventing the water in the outer drum from flowing back into the inner drum and contaminating the clothes.

[0051] Exemplarily, during the rinsing process, controlling water inflow into the inner drum and water out of the outer drum includes:

[0052] During the rinsing process, the inner drum is controlled to intermittently supply water, and the outer drum is controlled to drain water continuously or intermittently.

[0053] Here, during the rinsing process, the water inlet valve that guides water into the inner drum can be controlled to be intermittently turned on based on a set start-stop ratio, and the drain valve of the outer drum can be controlled to drain water continuously or intermittently based on a set start-stop ratio. It should be noted that based on the control of the water inlet valve and / or the drain valve, during the rinsing process, while the inner drum is continuously or intermittently supplied with water, the water level of the outer drum can always be greater than the rated minimum water level and less than the rated maximum water level.

[0054] It should be noted that during the rinsing process, the drainage holes on the inner drum are in a closed state, and the water after rinsing clothes in the inner drum can overflow into the outer drum through the clothing opening and be discharged in time by the drainage valve of the outer drum, thereby preventing the water in the outer drum from flowing back into the inner drum and contaminating the clothes.

[0055] In some embodiments, determining that the water level of the outer barrel meets a preset condition includes:

[0056] If the load of the clothes is a large load, it is determined that the water level of the outer tub is greater than or equal to the set water level and less than the rated maximum water level;

[0057] If the load of the clothes is a small load, it is determined that the water level of the outer tub is a rated minimum water level and is less than the set water level.

[0058] Exemplarily, the set water level is the water level corresponding to the lower edge of the inner drum, and the rated maximum water level is the water level corresponding to the lower edge of the clothing opening.

[0059] It is understandable that a water level sensor for detecting the water level is provided in the outer barrel, so that the water level in the outer barrel can be detected. For the structure of the outer barrel and the inner barrel with holes, due to the connection structure between the inner barrel and the outer barrel, the water level will drop after the injected water is absorbed by the clothes. The water level sensor senses the drop in the water level and can replenish water in time to maintain the water level in the inner barrel at the set height. Under such water inlet logic, the washing program can take in different amounts of water according to loads of different masses and materials to fully wet the clothes, thereby achieving the best washing and rinsing effects.

[0060] In the embodiment of the present application, considering the influence of the inner drum rotation, the clothes absorbing water, etc. on the water level in the inner drum, it is possible to reasonably judge whether the water level in the inner drum is reasonable based on the change in the water level in the outer drum caused by the water in the inner drum overflowing into the outer drum. In this way, for the structure of the inner drum without holes, during the rinsing water inlet process, rinsing is started after determining that the water level in the outer drum meets the preset conditions, which can ensure that the clothes are fully wetted and save water when the amount of clothes is reduced.

[0061] For example, Figure 3 As shown, the outer drum 2 is provided with a water level sensor for detecting the water level, the inner drum 1 is rotatably provided in the outer drum 2, and the clothing opening of the inner drum 1 forms the inner drum front 1A. The water level P1 is the lowest water inlet level during the rinsing process (i.e., the rated lowest water inlet level), and its height is mainly determined by the accuracy of the water level sensor. The rinsing water level P must be higher than P1 for the washing machine to work normally; the water level P2 is the water level corresponding to the lower edge of the inner drum (i.e., the aforementioned set water level); the water level P3 is the water level corresponding to the lower edge of the clothing opening (i.e., the aforementioned rated highest water level). In order to prevent the dirty water in the outer drum from flowing back into the inner drum, the rinsing water level P must be lower than the water level P3.

[0062] In the embodiment of the present application, the rinsing water level P can be adjusted according to the size of the clothing load, and can be compared with the set threshold value according to the clothing load determined before washing. If the clothing load is greater than the set threshold value, the clothing load is determined to be a large load, and if the clothing load is less than or equal to the set threshold value, the clothing load is determined to be a small load. For a small load, the rinsing water level P can be set between P1 and P2. At this time, the amount of water injected into the inner drum is sufficient to rinse the clothes; for a large load, the rinsing water level P can be set between P2 and P3. After more water is injected, the clothes in the inner drum can be fully rinsed. Setting the rinsing water level in this way can not only ensure that the clothes are fully rinsed, but also effectively save water resources.

[0063] Exemplarily, the control method further includes:

[0064] If it is determined that the number of rinses is less than the set number, the rinse cycle will be performed until the number of rinses reaches the set number, and then the rinse cycle will be exited.

[0065] It is understandable that if there are multiple rinsing requirements, the aforementioned rinsing water inlet and rinsing control can be repeatedly performed until rinsing is completed and rinsing is exited.

[0066] Exemplarily, before rinsing water, the control method further includes:

[0067] Run the wash cycle, drain and spin.

[0068] It is understandable that the drum washing machine can first wash the clothes in the inner drum based on the washing program, and after draining and dehydrating, perform the aforementioned rinsing control.

[0069] It should be noted that during the drainage and dehydration stage, the drainage holes on the inner drum can be opened to drain the residual water in the inner drum, so as to facilitate subsequent sufficient rinsing.

[0070] Exemplarily, after exiting rinsing, the control method further includes:

[0071] Drain and dehydrate.

[0072] It is understandable that after the drum washing machine performs the rinsing control, it can perform the final drainage and dehydration to reduce the water content of the washed clothes. Preferably, the drum washing machine can also perform a drying process on the clothes, and the relevant process is not repeated here.

[0073] The present application is further described in detail below in conjunction with application examples.

[0074] like Figure 4 As shown, the control method of the drum washing machine of this application embodiment includes:

[0075] Step 401, rinse water is fed in, and the water is fed in to the rinse water level P.

[0076] Here, after the drum washing machine completes the washing program and drains and spins, it can perform rinsing water intake until the water reaches the rinsing water level P, that is, the water level sensor detects that the water level in the outer tub reaches the rinsing water level P.

[0077] Here, the corresponding rinsing water level P can be determined based on the laundry load. If the laundry load is a small load, the rinsing water level P can be set between P1 and P2; if the laundry load is a large load, the rinsing water level P can be set between P2 and P3.

[0078] Step 402, start rinsing.

[0079] Step 403, water is introduced into the inner drum and drainage is started at the same time.

[0080] It is understandable that during the rinsing process, the inner drum is filled with water and the outer drum is drained. Here, during the rinsing process, the water inlet valve controlling the water inlet of the inner drum can continuously or intermittently fill water, and the drainage pump of the outer drum can continuously or intermittently drain water, which is not specifically limited here.

[0081] It should be noted that during the rinsing process, the water level in the outer tub needs to be greater than P1 and less than P3, that is, the normal operation of rinsing needs to be met, and the water in the outer tub cannot flow back into the inner tub.

[0082] Step 404, rinsing is completed and water supply is stopped.

[0083] It is understandable that if there are multiple rinsing requirements, the aforementioned rinsing water intake and rinsing control can be repeatedly performed until rinsing is completed, water intake is stopped, and rinsing is exited.

[0084] Step 405, draining and dehydrating.

[0085] For example, the drainage holes on the inner drum can be opened, and the inner drum can be driven to rotate at a high speed, so that the excess water on the clothes and the water in the inner drum can be drained through the centrifugal force.

[0086] In order to implement the method of the embodiment of the present application, the embodiment of the present application also provides a control device for a drum washing machine, which corresponds to the control method of the drum washing machine mentioned above, and each step in the embodiment of the control method of the drum washing machine mentioned above is also fully applicable to the embodiment of the control device of the present drum washing machine.

[0087] like Figure 5 As shown, the control device of the drum washing machine includes: a control module 501, which is used to determine that the water level of the outer drum meets the preset conditions during the rinsing water inlet process, and then start rinsing; during the rinsing process, control the water inlet of the inner drum and the water outlet of the outer drum;

[0088] Wherein, the preset conditions at least include: the water level of the outer tub is greater than the rated minimum water level; during the rinsing process, the water level of the outer tub is greater than the rated minimum water level and less than the rated maximum water level.

[0089] In some embodiments, the control module 501 is specifically used to:

[0090] During the rinsing process, the inner drum is controlled to continuously inlet water, and the outer drum is controlled to continuously drain water or intermittently drain water.

[0091] In some embodiments, the control module 501 is specifically used to:

[0092] During the rinsing process, the inner drum is controlled to intermittently supply water, and the outer drum is controlled to drain water continuously or intermittently.

[0093] In some embodiments, the control module 501 determines that the water level of the outer tub meets a preset condition, including:

[0094] If the load of the clothes is a large load, determining that the water level of the outer tub is greater than or equal to the set water level and less than the rated maximum water level;

[0095] If the load of the clothes is a small load, it is determined that the water level of the outer tub is greater than the rated minimum water level and less than the set water level.

[0096] Exemplarily, the set water level is the water level corresponding to the lower edge of the inner drum, and the rated maximum water level is the water level corresponding to the lower edge of the clothing opening.

[0097] In some embodiments, the control module 501 is further configured to:

[0098] If it is determined that the number of rinses is less than the set number, the rinse cycle will be performed until the number of rinses reaches the set number, and then the rinse cycle will be exited.

[0099] In some embodiments, before rinsing, the control module 501 is further used to:

[0100] Run the wash cycle, drain and spin.

[0101] In some embodiments, after exiting the rinse cycle, the control module 501 is further configured to:

[0102] Drain and dehydrate.

[0103] In actual application, the control module 501 can be implemented by a processor in the control device of the drum washing machine. Of course, the processor needs to run the computer program in the memory to implement its function.

[0104] It should be noted that: the control device for the drum washing machine provided in the above embodiment only uses the division of the above program modules as an example when controlling the drum washing machine. In actual applications, the above processing can be assigned to different program modules as needed, that is, the internal structure of the device is divided into different program modules to complete all or part of the above-described processing. In addition, the control device for the drum washing machine provided in the above embodiment and the control method embodiment of the drum washing machine belong to the same concept. The specific implementation process is detailed in the method embodiment and will not be repeated here.

In addition to the data bus, the bus system 604 also includes a power bus, a control bus and a status signal bus. However, for the sake of clarity, in Figure 6 Various buses are labeled as bus system 604 .

[0107] The drum washing machine of the embodiment of the present application further includes: an outer drum and an inner drum rotating relative to the outer drum. It is understandable that the inner drum has a clothing opening for taking out and putting clothes, and the clothing opening forms the front edge of the inner drum and can allow water to enter the inner drum. In order to facilitate the drainage of the inner drum, a closable drainage hole can be provided on the wall of the inner drum. For example, an electromagnetic switch or a centrifugal switch based on the centrifugal force of rotation can be provided at the drainage hole, and the embodiment of the present application does not limit this.

[0110] The control method of the drum washing machine disclosed in the embodiment of the present application can be applied to the processor 601, or implemented by the processor 601. The processor 601 may be an integrated circuit chip with signal processing capabilities. In the implementation process, each step of the control method of the drum washing machine can be completed by the hardware integrated logic circuit in the processor 601 or the instructions in the form of software.
