Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and in particular, relates to a washing machine control method and a washing machine. Background Art

[0002] The existing drainage method of the pulsator washing machine is static drainage, that is, after the main wash or rinse process is completed, the inner drum is drained in a static state. After the water is drained to the set water level, the inner drum is controlled to operate at a step-by-step increasing speed to perform dehydration.

[0003] Under this drainage method, the clothes in the barrel are prone to eccentric and uneven distribution during dehydration due to the rotation of the washing process, especially when some large clothes, clothes that absorb heavy water, or multiple types of clothes are washed together. As a result, the inner barrel is prone to hit the box and the control lever during dehydration, and the dehydration success rate is low. Summary of the invention

[0004] The purpose of the present invention is to provide a washing machine control method and a washing machine, which change the static drainage and dehydration mode of the pulsator washing machine, control the inner drum to rotate during drainage, and evenly disperse the laundry in advance before dehydration, thereby reducing the probability of hitting the box body and the control rod during dehydration and improving the success rate of dehydration.

[0005] The present invention is implemented by the following technical solutions: A washing machine control method is proposed, comprising: Control the inner barrel to be still and start the drainage process; Check the water level in the bucket during drainage; When the water level drops to a first set water level, the inner barrel is controlled to rotate according to a set speed; After draining to the lower limit water level, the dehydration process is started at the set speed.

[0006] Compared with the prior art, the advantages and positive effects of the present invention are as follows: in the control method of the washing machine proposed by the present invention, after the washing process or the rinsing process is completed, the drainage process is entered. In the drainage process, the inner barrel is first controlled to be stationary according to the conventional drainage method and the drainage valve is opened to start drainage. Then, the water level in the barrel is monitored during the drainage process. When the water level in the barrel drops to the first set water level, the inner barrel is controlled to rotate at a set speed. The inner barrel rotates at the set speed to drive the water in the barrel to form a rotating water flow. The rotating water flow drives the laundry to rotate, so that the laundry is evenly distributed during the drainage process. That is, in the design of the present invention, the drainage is implemented synchronously with the rotation of the inner barrel. During the drainage process, the laundry is evenly distributed based on the rotation of the inner barrel, which does not affect the progress of the drainage process. When the water level drops to the lower limit water level, the laundry is basically evenly distributed at the bottom of the inner barrel. At this time, the inner barrel does not stop, and directly enters the dehydration process at the set speed. Since the laundry has been evenly distributed before entering the dehydration process, there is no eccentricity, which reduces the possibility of the inner barrel hitting the box and the control rod during dehydration, so that the dehydration process can proceed smoothly. Compared with the existing dehydration method of the pulsator washing machine, the dehydration success rate can be significantly improved.

[0007] In some embodiments of the present invention, controlling the inner barrel to rotate according to a set speed specifically includes: When the water level drops to a first set water level, the inner barrel is controlled to rotate according to a first set speed; After the first set time, the inner barrel is controlled to rotate according to the second set speed; When the water level drops to the second set water level, the inner barrel is controlled to rotate according to the third set speed until it reaches the lower limit water level; Wherein, the first set speed is lower than the second set speed, and the second set speed is lower than the third set speed; then, After draining water to the minimum water limit, the dehydration process is entered at the third set speed.

[0008] In this embodiment, when the water level in the barrel drops to the first set water level, the inner barrel is first controlled to rotate at the first set speed, and the inner barrel rotating at the first set speed drives the water flow, so that the laundry in the barrel is slowly and evenly distributed along with the rotating water flow while draining. After the first set time, the speed of the inner barrel is increased to the second set speed, and the second set speed is higher than the first set speed, so that the range of the water area near the inner barrel is expanded, and the laundry is further evenly distributed with the rotating water flow with an expanded range on the basis of the initial uniform distribution. When the water level drops to the second set water level, the speed of the inner barrel is increased again to the third set speed. On the one hand, the range of the water area near the inner barrel is further diffused, so that the laundry is finally evenly distributed under the action of the rotating water flow with a further expanded range. At the same time, because the range of the rotating water flow caused by the high speed is larger, the laundry is initially dispersed toward the inner wall of the inner barrel based on the centrifugal effect, which is more conducive to the implementation of the dehydration process. When the water level drops to the lower limit water level, the laundry is evenly distributed in advance before dehydration and moves closer to the inner wall of the inner barrel. At this time, the dehydration process is directly switched to the dehydration process at the third set speed, which can significantly improve the dehydration success rate and dehydration efficiency.

[0009] In some embodiments of the present invention, the method further comprises: determining the first set time and the second set water level based on the type of washing course, the weight of the laundry, and the type of the laundry.

[0010] The type of washing process, the weight of the laundry and the type of laundry affect the time during which the laundry can be effectively and evenly distributed as it rotates with the water flow. If the time is too short, the laundry cannot be effectively and evenly distributed. Therefore, in this embodiment, the first set time for rotation at the first set speed at the first set water level is determined according to the type of washing process, the weight of the laundry and the type of laundry. After the laundry is evenly distributed under the action of the inner drum at the first set speed and the first set time, a sufficient second set water level is required to disperse the laundry near the inner wall of the inner drum at a third set speed. At the second set water level, the laundry can be preliminarily dispersed toward the inner wall of the inner drum based on the centrifugal effect. Therefore, in this embodiment, the second set water level is determined according to the type of washing process, the weight of the laundry and the type of laundry.

[0011] In some embodiments of the present invention, the method further comprises: before entering the dehydration process at the set speed, controlling the rotation of the inner barrel to satisfy a second set time.

[0012] In this embodiment, after the water is drained to the lower limit water level, the laundry that has fallen to the bottom of the barrel has been basically evenly distributed, and the inner barrel continues to rotate at the set speed for the second set time. During this time period, the laundry is based on the rotation of the inner barrel, and the part located at the center of the bottom of the barrel moves toward the inner wall of the inner barrel due to centrifugal force, so that the laundry is not only evenly distributed before the dehydration process, but also moves toward the inner wall of the inner barrel, which is more conducive to the start and execution of the dehydration process.

[0013] In some embodiments of the present invention, the method further comprises: The first set water level and the set rotation speed are determined based on the type of washing course, the weight of the laundry and the type of the laundry, so that the water flow caused by the inner tub at the set rotation speed can drive all the laundry in the tub to rotate.

[0014] The type of washing process, the weight of the laundry and the type of washing all affect the washing water level, which in turn affects the first set water level that can ensure that the laundry is driven by the water flow and rotates with the water flow. If the first set water level is insufficient, the laundry cannot be effectively driven by the water flow and cannot be effectively evenly distributed. If the first set water level is too high, the power consumption of the inner barrel rotation will increase. The rotation speed of the inner barrel determines the strength of the water flow driven by the water near it, and whether the laundry can be driven to rotate by the water flow is affected by the weight and type of laundry. The influence of the type, insufficient inner drum speed will result in the laundry being unable to be effectively driven by the water flow and unable to be effectively evenly distributed, and too high an inner drum speed will increase the power consumption of the inner drum rotation. Therefore, the set speed at which the laundry can be driven by the water flow and rotate with the water flow is affected by the weight of the laundry and the type of laundry; therefore, in this embodiment, in order to ensure that the rotation of the inner drum can effectively drive the laundry to be evenly distributed and avoid consuming unnecessary power consumption, the first set water level and the set speed are determined according to the type of washing process, the weight of the laundry and the type of laundry; in specific implementation, it can be obtained according to a set mathematical model or a table lookup method, and this embodiment is not specifically limited.

[0015] A washing machine is provided, which is configured with a drainage process and a dehydration process, comprising: A controller, used to control the inner barrel to stop, start and control the drainage process; A water level detection module, used to detect the water level in the barrel during drainage; The controller receives the detection data of the water level detection module, and controls the rotation of the inner drum according to the set speed when the water level drops to the first set water level; after draining to the lower limit water level, controls the washing machine to enter the dehydration process at the set speed.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: the washing machine proposed by the present invention enters the drainage process after the washing process or the rinsing process is completed. During the drainage process, the inner barrel is first controlled to be stationary according to the conventional drainage method and the drainage valve is opened to start drainage. Then, the water level in the barrel is monitored during drainage. When the water level in the barrel drops to the first set water level, the inner barrel is controlled to rotate at a set speed. The inner barrel rotates at the set speed to drive the water in the barrel to form a rotating water flow. The rotating water flow drives the laundry to rotate, so that the laundry is evenly distributed during drainage. That is, in the design of the present invention, drainage and inner barrel are integrated. The rotation is implemented synchronously. During the drainage period, the laundry is evenly distributed based on the rotation of the inner drum, which does not affect the progress of the drainage process. When the water level drops to the lower limit water level, the laundry is basically evenly distributed on the bottom of the inner drum. At this time, the inner drum does not stop, but directly enters the dehydration process at the set speed. Since the laundry has been evenly distributed before entering the dehydration process, there is no eccentricity, which reduces the possibility of the inner drum hitting the box and the control lever during dehydration, so that the dehydration process can proceed smoothly. Compared with the existing dehydration method of the pulsator washing machine, the dehydration success rate can be significantly improved, thereby improving the user experience.

[0017] In some embodiments of the present invention, when the controller controls the inner barrel to rotate according to the set speed, the controller specifically includes: When the water level drops to a first set water level, the inner barrel is controlled to rotate according to a first set speed; After the first set time, the inner barrel is controlled to rotate according to the second set speed; When the water level drops to the second set water level, the inner barrel is controlled to rotate according to the third set speed until it reaches the lower limit water level; Wherein, the first set speed is lower than the second set speed, and the second set speed is lower than the third set speed; then, After draining to the minimum water limit, the dehydration process is entered at the third set speed.

[0018] In some embodiments of the present invention, the controller is further used to: before entering the dehydration process at the set speed, control the rotation of the inner barrel to meet a second set time.

[0019] In some embodiments of the present invention, the controller is also used to determine the first set water level and the set speed based on the type of washing process, the weight of the laundry and the type of laundry, so that the water flow caused by the inner barrel at the set speed can drive all the laundry in the barrel to rotate.

[0020] In some embodiments of the present invention, the controller is further configured to determine the first set time and the second set water level based on the type of washing process, the weight of the laundry, and the type of the laundry.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0028] The washing machine control method proposed in the present invention aims to solve the technical problem that the pulsator washing machine is prone to hit the cabinet and the control rod due to the eccentricity of the clothes during dehydration. Specifically, Figure 1 As shown, the following steps are included: Step S1: Control the inner barrel to be still and start the drainage process.

[0029] When the washing process or the rinsing process is finished, the inner barrel is controlled to be still and the drainage process is started. The starting of the drainage process includes starting the drainage pump and the drainage valve.

[0030] Step S2: Detect the water level in the bucket during drainage.

[0031] A water level sensor or other existing water level detection method is used to obtain water level change data during drainage.

[0032] Step S3: When the water level drops to the first set water level, the inner barrel is controlled to rotate according to the set speed.

[0033] When the water level in the barrel drops to the first set water level, the inner barrel is controlled to rotate at a set speed. The inner barrel rotates at the set speed to drive the water in the barrel to form a rotating water flow, and the rotating water flow drives the laundry to rotate, so that the laundry is evenly distributed during drainage. That is, in the design of the present invention, drainage and the rotation of the inner barrel are implemented synchronously. During drainage, the laundry is evenly distributed based on the synchronous rotation of the inner barrel, which does not affect the progress of the drainage process.

[0034] Step S4: After draining to the lower limit water level, enter the dehydration process at the set speed.

[0035] When the water level drops to the lower limit, the laundry is basically evenly distributed at the bottom of the inner drum. At this time, the inner drum does not stop, but directly enters the dehydration process at the set speed. Since the laundry has been evenly distributed before entering the dehydration process, there is no eccentricity, which reduces the possibility of the inner drum hitting the box and the control lever during dehydration, so that the dehydration process can proceed smoothly. Compared with the existing dehydration method of the pulsator washing machine, the dehydration success rate can be significantly improved.

[0036] The following describes in detail the control of the washing machine control method during the washing machine drainage period according to the present invention with reference to several specific embodiments.

[0037] In some embodiments of the present invention, Figure 2 As shown, the control of the drainage process includes the following steps: S21: Control the inner barrel to be still and start the drainage process.

[0038] S22: Determine a first set water level and a set rotation speed based on the type of washing process, the weight of the laundry and the type of laundry, so that the water flow caused by the inner tub at the set rotation speed can drive all the laundry in the tub to rotate.

[0039] The type of washing process, the weight of the laundry and the type of washing all affect the washing water level, which in turn affects the first set water level that can ensure that the laundry is driven by the water flow and rotates with the water flow. If the first set water level is insufficient, the laundry cannot be effectively driven by the water flow and cannot be effectively and evenly distributed. If the first set water level is too high, the power consumption of the inner drum rotation will increase.

[0040] The rotation speed of the inner barrel determines the strength of the water flow driven by the water near it, and whether the laundry can be driven by the water flow to rotate is affected by the weight and type of laundry. The rotation speed of the inner barrel determines the strength of the water flow driven by the water near it, and whether the laundry can be driven by the water flow to rotate is affected by the weight and type of laundry. Insufficient inner barrel rotation speed will result in the laundry being unable to be effectively driven by the water flow and unable to be effectively and evenly distributed. Excessively high inner barrel rotation speed will increase the power consumption of the inner barrel rotation. Therefore, the set rotation speed at which the laundry can be driven by the water flow and rotate with the water flow is affected by the weight and type of laundry.

[0041] Therefore, in this embodiment, in order to ensure that the rotation of the inner drum can effectively drive the laundry to be evenly distributed and avoid unnecessary power consumption, in order to achieve uniform distribution of the laundry while draining, the first set water level and the set speed are determined according to the type of washing process, the weight of the laundry and the type of laundry.

[0042] In specific implementation, it can be obtained according to a set mathematical model (for example, a weighted model with the type of washing process, the weight of the laundry and the type of laundry as parameters, and the model outputs the water level level and the inner barrel speed) or a table lookup method (with the type of washing process, the weight range of the laundry and the type of laundry as influencing items, and the corresponding water level and inner barrel speed are obtained according to empirical statistics), which is not specifically limited in this embodiment.

[0043] S23: Detect the water level in the barrel during drainage.

[0044] S24: When the water level drops to the first set water level, the inner barrel is controlled to rotate according to the set speed.

[0045] When the water level in the barrel drops to the first set water level, the inner barrel is controlled to rotate at a set speed. The inner barrel rotates at the set speed to drive the water in the barrel to form a rotating water flow, and the rotating water flow drives the laundry to rotate, so that the laundry is evenly distributed during drainage. That is, in the design of the present invention, drainage and the rotation of the inner barrel are implemented synchronously. During drainage, the laundry is evenly distributed based on the synchronous rotation of the inner barrel, which does not affect the progress of the drainage process.

[0046] S25: After draining to the lower limit water level, the inner barrel is controlled to rotate to meet the second set time.

[0047] In this embodiment, after the water is drained to the lower limit water level, the laundry that has fallen to the bottom of the barrel has been basically evenly distributed, and the inner barrel continues to rotate at the set speed for the second set time. During this time period, the laundry is based on the rotation of the inner barrel, and the part located at the center of the bottom of the barrel is dispersed and moved toward the inner wall of the inner barrel due to centrifugal force. This allows the laundry to be not only evenly distributed before the dehydration process, but also move closer to the inner wall of the inner barrel, which is more conducive to the start and execution of the dehydration process.

[0048] The lower limit water level here is, for example, 0 water level, for example, a water level determined by the amount of water that can be dispersed during the dehydration process, etc.

[0049] S26: Entering the dehydration process at the set speed.

[0050] In some embodiments of the present invention, Figure 3 As shown, the control of the drainage process includes the following steps: Step S31: After the washing process or the rinsing process is finished, the inner tub is controlled to be stationary and the drainage process is started.

[0051] Step S32: During drainage, the water level in the barrel is detected, and when the water level drops to a first set water level, the inner barrel is controlled to rotate according to a first set speed.

[0052] When the water level in the barrel drops to the first set water level, the inner barrel is first controlled to rotate at the first set speed. The inner barrel rotating at the first set speed drives the water nearby to form a rotating water flow, so that the laundry in the barrel is slowly and evenly distributed along the rotating water flow while being drained.

[0053] Step S33: After the first set time, the inner barrel is controlled to rotate according to the second set speed.

[0054] After the first set time, the inner barrel speed is increased to a second set speed, which is higher than the first set speed, so that the water area near the inner barrel is expanded, and the laundry is further evenly distributed on the basis of the initial uniform distribution with the expanded range of rotating water flow.

[0055] Step S34: When the water level drops to the second set water level, the inner barrel is controlled to rotate according to the third set speed until it reaches the lower limit water level.

[0056] When the water level drops to the second set water level, the speed of the inner drum wheel is increased to the third set speed again. On the one hand, the water area near the inner drum is further expanded, so that the laundry is finally evenly distributed under the action of the further expanded rotating water flow. At the same time, because the rotating water flow caused by the high speed has a larger range, the laundry is initially dispersed toward the inner wall of the inner drum based on the centrifugal effect, which is more conducive to the implementation of the dehydration process.

[0057] Step S35: Control the washing machine to enter the dehydration process at the third set speed.

[0058] When the water level drops to the lower limit, the laundry is evenly distributed in advance and moves closer to the inner wall of the barrel before dehydration. At this time, the dehydration process is directly switched to the third set speed, which can significantly improve the dehydration success rate and dehydration efficiency.

[0059] In the present embodiment, during the whole drainage process, the rotation speed of the impeller is gradually increased. First, a preliminary uniform distribution of the laundry is implemented with a slow and small-range rotating water flow. Then, the rotation speed of the inner barrel is gradually increased, and the rotating water flow range is gradually expanded to gradually improve the uniform distribution effect. In the later stage of uniform distribution, the laundry is dispersed toward the inner wall of the inner barrel at a relatively high rotation speed. Finally, the dehydration process is directly switched to a slightly higher rotation speed, which can significantly improve the dehydration success rate and save the execution time of the dehydration process. Moreover, due to the implementation of uniform distribution in the early stage, the laundry has been initially evenly distributed, which makes it easier to gradually increase the rotation speed of the inner barrel in the later stage.

[0060] In actual applications, factors such as the type of washing process, the weight of the laundry, and the type of laundry all affect the time it takes for the laundry to be effectively and evenly distributed as the water rotates. If the time is too short, the laundry cannot be effectively and evenly distributed. If the time is too long, the execution time of the drainage process will be increased and the subsequent distribution processing effect will be delayed. Therefore, if the time is too short, the laundry cannot be effectively and evenly distributed. Figure 4 As shown, in this embodiment, Figure 3 Before step S33 of the illustrated embodiment, step S330 is added to determine a first set time for rotation at a first set speed at a first set water level according to the type of washing process, the weight of the laundry and the type of the laundry.

[0061] After the laundry is evenly distributed under the action of the inner drum at the first set speed and the first set time, in order to disperse the laundry near the inner wall of the inner drum at the third set speed, a sufficient second set water level is required. At the second set water level, the laundry can be preliminarily dispersed toward the inner wall of the inner drum based on the centrifugal effect. Therefore, in this embodiment, Figure 3In the illustrated embodiment, step S340 is added before step S34 to determine the second set water level according to the type of washing course, the weight of the laundry and the type of the laundry.

[0062] As mentioned above, in specific implementation, the first set time and the second set water level can be obtained according to a set mathematical model or a table lookup method, and this embodiment does not specifically limit this.

[0063] The present invention also proposes a washing machine, which is configured with the above washing machine control method, and includes: a controller and a water level detection module, wherein the controller controls the inner drum to be stationary, starts and controls the drainage process after the washing process or the rinsing process is completed; the water level detection module detects the water level in the drum during drainage; the controller receives the detection data of the water level detection module, and when the water level drops to a first set water level, controls the inner drum to rotate according to a set speed; after draining to the lower limit water level, controls the washing machine to enter the dehydration process at the set speed.

[0064] In some embodiments of the present invention, when the controller controls the rotation of the inner barrel according to the set speed, specifically includes: when the water level drops to a first set water level, controlling the rotation of the inner barrel according to a first set speed; after a first set time, controlling the rotation of the inner barrel according to a second set speed; when the water level drops to a second set water level, controlling the rotation of the inner barrel according to a third set speed until the lower limit water level; wherein the first set speed is lower than the second set speed, and the second set speed is lower than the third set speed; then, after draining water to the lower limit water level, the controller controls the inner barrel to enter the dehydration process at the third set speed.

[0065] In some embodiments of the present invention, the controller is further used to: before entering the dehydration process at a set speed, control the rotation of the inner barrel to meet a second set time.

[0066] In some embodiments of the present invention, the controller is also used to determine a first set water level and a set rotation speed based on the type of washing process, the weight of the laundry and the type of laundry, so that the water flow caused by the inner barrel at the set rotation speed can drive all the laundry in the barrel to rotate.

[0067] In some embodiments of the present invention, the controller is further configured to determine the first set time and the second set water level based on the type of washing course, the weight of the laundry and the type of the laundry.
