Description

Technical Field

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

[0002] Washing machines are essential appliances for everyday life. With technological advancements, the washing process is becoming increasingly intelligent. Currently, twin-drum, fully automatic front-loading, and pulsator washing machines all automatically fill and drain water during the wash and rinse cycles. The water level in the drum during both the wash and rinse cycles significantly impacts the cleanliness of clothing and prevents damage.

[0003] At present, washing machines generally automatically sense the water level according to the amount of clothes put in, or the user defines a target water level. When the water level reaches the target level, the washing machine stops filling water and starts washing or rinsing.

[0004] However, in real-world scenarios, the amount of laundry loaded can vary, and some clothes may not be properly soaked. The washing machine's automatic water level sensing based on the laundry often deviates, resulting in low water levels. Using a user-defined target water level can also be inappropriate, leading to insufficient or excessive water during the wash. Both methods suffer from inaccurate water level control. If the water level is too low, clothes may dry out during the wash, ultimately resulting in poor washing results. Summary of the Invention

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] The terms "first," "second," "third," "fourth," and so forth (if any) in the description and claims of the present invention and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that, for example, the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product, or apparatus.

[0047] Currently, washing machines generally automatically sense the water level based on the amount of laundry loaded. For example, during the water filling process before washing, the system detects in real time whether the water level has reached the highest point of the laundry. If not, it continues filling until the water level reaches the highest point of the laundry or the maximum water level, and then begins washing. Alternatively, the user can customize the target water level. For example, before washing clothes, the user sets the target water level using the washing machine's operating buttons. When water filling begins, the water filling stops and washing begins when the water level in the drum reaches the target water level. However, in real-world scenarios, the amount of laundry loaded may vary, and some clothes may not be well soaked. The automatic water level sensing based on the laundry often deviates, resulting in low water levels. Using a user-defined target water level often results in inappropriate target water levels, which can easily lead to insufficient or excessive water filling during the washing process. Both methods have the problem of inaccurate water level control. If the water level is too low, clothes will dry out during the washing process, ultimately resulting in poor washing results.

[0048] In response to this defect, the technical concept of the present invention is mainly that: during the clothes washing process, the sound amplitude in the washing stage is detected in real time, and the detected sound amplitude is compared with the preset amplitude threshold. The degree of matching between the sound amplitude and the preset amplitude threshold can be accurately judged by the size of the sound amplitude and the preset amplitude threshold. When the sound amplitude is greater than the preset amplitude threshold, it means that the washing water level in the clothes washing stage is low relative to the current clothes load, and water needs to be added to increase the washing water level. When the sound amplitude is less than the preset amplitude threshold, it means that the current washing water level is high and there is no need to increase the water level. After the washing stage ends and the rinse stage begins, the normal rinse water level is higher than the washing water level. At this time, since the washing water level is higher, there is no need to execute the process of the rinse water level being higher than the washing water level. The rinse water level can be directly determined according to the washing water level. This process not only achieves precise control of the washing water level, but also saves water resources.

[0049] The water level control method for a washing device and the preferred technical solution for the washing device of the present invention will be described below in conjunction with the above-mentioned drawings.

[0050] Figure 1 FIG. 1 is a flow chart of a water level control method for a washing machine according to an exemplary embodiment of the present invention.

[0051] like Figure 1 As shown, the method provided in this embodiment may include the following steps.

[0052] S101 , when it is detected that the current operation phase of the washing device enters the washing phase, detecting the sound amplitude in the drum of the washing device.

[0053] Specifically, when washing clothes, the washing machine usually includes processes such as the washing stage, the rinsing stage, the dehydration stage, and the drying stage. The controller inside the washing machine will monitor the current operation stage in real time. When it detects that the current operation stage enters the washing stage, it sends a detection instruction to the audio sensor. When receiving the detection instruction, the audio sensor starts to detect the sound amplitude of the washing stage.

[0054] In this step, the sound amplitude in the drum of the washing equipment is detected by an audio sensor, and the detection result obtained is more accurate.

[0055] S102 , determining the magnitude of the sound amplitude relative to a preset amplitude threshold; if the sound amplitude is greater than the preset amplitude threshold, determining an increment of the sound amplitude relative to the preset amplitude threshold.

[0056] Among them, the preset amplitude threshold can be determined in advance through a large amount of washing test data. For example, in a washing test, the washing data of each test is determined, and the washing data includes the washing water level and the clothing load. When the washing water level and the clothing load are determined, the sound amplitude of the washing stage corresponding to the washing data is detected and recorded, and a set of optimal washing data is selected according to the clothing washing effect, that is, it is determined under which washing data the washed clothes are both clean and wear-free (that is, the washing water level and the clothing load are well matched). The sound amplitude corresponding to the optimal washing data can be used as the preset amplitude threshold.

[0057] Specifically, the sound amplitude during the wash phase can reflect the compatibility between the current wash water level and the laundry load. Therefore, the sound amplitude is compared to a preset amplitude threshold. If the sound amplitude exceeds the threshold, it indicates that the current wash water level is too low. Continuing to wash will wear out the laundry, and the wash water level needs to be adjusted. The increment in sound amplitude relative to the threshold is then determined.

[0058] In one or more possible embodiments, the increment of the sound amplitude relative to the preset amplitude threshold is determined by determining the difference between the sound amplitude and the preset amplitude threshold, and taking the ratio of the difference to the preset amplitude threshold as the increment.

[0059] S103, controlling the washing water level according to the increment.

[0060] Specifically, the increment of the sound amplitude detected in real time relative to the preset amplitude threshold is different, and the control of the washing water level is also different, so the washing water level is controlled by the increment.

[0061] In this embodiment, when it is monitored that the current operation stage of the washing device enters the washing stage, the sound amplitude in the drum of the washing device is detected; then the size of the sound amplitude and the preset amplitude threshold are judged, and the matching degree between the sound amplitude and the preset amplitude threshold can be accurately judged through the size of the sound amplitude and the preset amplitude threshold. If the sound amplitude is greater than the preset amplitude threshold, it means that the current washing water level is low, and then the increment of the sound amplitude relative to the preset amplitude threshold is determined; finally, the washing water level is controlled by the increment, so that the washing water level can be accurately controlled during the washing process, thereby enhancing the washing effect.

[0062] Figure 2 is a flow chart of a water level control method for a washing machine according to another exemplary embodiment of the present invention. Figure 2 Based on the illustrated embodiment, a water level control method for a washing device is further described in detail.

[0063] like Figure 2 As shown, the method provided in this embodiment may include the following steps.

[0064] S201 , when it is detected that the current operation phase of the washing device enters the washing phase, detecting the sound amplitude in the drum of the washing device.

[0065] Specifically, when washing clothes, the washing machine usually includes processes such as the washing stage, the rinsing stage, the dehydration stage, and the drying stage. The controller inside the washing machine will monitor the current operation stage in real time. When it detects that the current operation stage enters the washing stage, it sends a detection instruction to the audio sensor. When receiving the detection instruction, the audio sensor starts to detect the sound amplitude of the washing stage.

[0066] In this step, the sound amplitude in the drum of the washing equipment is detected by an audio sensor, and the detection result obtained is more accurate.

[0067] S202, recording the target washing water level of the washing equipment during the washing stage.

[0068] Specifically, the controller in the washing device records and saves the target washing water level of the washing stage sensed by the sensor, so that the target washing water level can be used when controlling the rinsing water level of the rinsing stage when the sound amplitude is less than the preset amplitude threshold.

[0069] S203, determining the size of the sound amplitude and a preset amplitude threshold. If the sound amplitude is greater than the preset amplitude threshold, executing steps S2041 to S2043; if the sound amplitude is less than the preset amplitude threshold, executing steps S2044 to S2045.

[0070] Specifically, the sound amplitude during the washing stage can reflect the matching between the current washing water level and the clothing load. Therefore, it is necessary to judge the size of the sound amplitude and the preset amplitude threshold. When the sound amplitude is greater than the preset amplitude threshold, it means that the current washing water level is too low. If washing continues, it will wear out the clothes, and the washing water level needs to be adjusted. When the sound amplitude is less than the preset amplitude threshold, it means that the current washing water level is too high.

[0071] In one or more possible embodiments, Figure 2 As shown, the step of controlling the washing water level according to the increment includes:

[0072] S2041: Determine an increment of the sound amplitude relative to the preset amplitude threshold.

[0073] Specifically, the increment of the sound amplitude relative to the preset amplitude threshold is determined by determining the difference between the sound amplitude and the preset amplitude threshold, and taking the ratio of the difference to the preset amplitude threshold as the increment.

[0074] S2042: Determine the water replenishment amount according to the increment.

[0075] In this step, the amount of water to be replenished is determined based on the increment, including: if the increment is less than or equal to a first threshold, determining the amount of water to be replenished is a first value; if the increment is greater than the first threshold and less than or equal to a second threshold, determining the amount of water to be replenished is a second value; if the increment is greater than the second threshold and less than or equal to a third threshold, determining the amount of water to be replenished is a third value.

[0076] The first threshold is smaller than the second threshold, the second threshold is smaller than the third threshold, the first value is smaller than the second value, and the second value is smaller than the third value.

[0077] Specifically, when the sound amplitude is greater than the preset amplitude threshold, it means that the current water level is low and water needs to be added. The amount of water to be added is determined based on the increment of the sound amplitude relative to the preset amplitude threshold. Generally, the larger the increment, the greater the amount of water to be added.

[0078] It should be noted that the amount of water added does not exceed the upper limit of the water capacity of the washing equipment. During the water adding process, the washing equipment automatically senses the water level through the sensor. When it senses that the water level has reached the upper limit, it stops adding water, thereby avoiding the water capacity exceeding the upper limit and damaging the washing equipment.

[0079] It should be noted that the first threshold value can be 20%, the second threshold value can be 30%, and the third threshold value can be 40%. The first value, the second value and the third value need to be determined based on the overall capacity of the washing equipment. For example, the first value can be 5 liters (L), the second value can be 10L, and the third value can be 20L.

[0080] For example, when the sound amplitude is greater than the preset amplitude threshold, it is considered that the washing water level is low during the laundry load washing process, and the water replenishment program needs to be set; when the increment of the sound amplitude relative to the preset amplitude threshold is greater than zero and less than or equal to 20%, the controller of the washing device automatically controls the replenishment of 5L of water based on the current washing water level according to the preset program; when the increment of the sound amplitude relative to the preset amplitude threshold is greater than 20% and less than or equal to 30%, the controller of the washing device automatically controls the replenishment of 10L of water based on the current washing water level according to the preset program; when the increment of the sound amplitude relative to the preset amplitude threshold is greater than 30% and less than or equal to 40%, the controller of the washing device automatically controls the replenishment of 20L of water based on the current washing water level according to the preset program.

[0081] S2043: Add water into the drum according to the replenished water amount to adjust the washing water level.

[0082] Specifically, after determining the replenishment water volume corresponding to the increment of the sound amplitude relative to the preset amplitude threshold, the controller of the washing equipment controls the water inlet valve of the washing equipment to open, starts to inject water according to the replenishment water volume, and controls the water inlet valve to close when the injected water volume reaches the determined replenishment water volume.

[0083] It should be noted that the washing equipment automatically senses the water level through sensors, and stops adding water when it senses that the water level has reached the upper limit, thereby avoiding the water capacity exceeding the upper limit and damaging the washing equipment.

[0084] S2044: Determine a reduction in the sound amplitude relative to the preset amplitude threshold.

[0085] Specifically, a difference between a preset amplitude threshold and the sound amplitude is determined, and a ratio of the difference to the preset amplitude threshold is used as a reduction in the sound amplitude relative to the preset amplitude threshold.

[0086] S2045: Control the rinsing water level of the washing device in the rinsing stage according to the reduction amount.

[0087] In this step, the rinsing water level of the washing device in the rinsing stage is determined based on the reduction amount, including: when monitoring that the current operation stage of the washing device enters the rinsing stage from the washing stage, if it is determined that the reduction amount is less than or equal to the fourth threshold value, then determining that the rinsing water level is equal to the target washing water level; if it is determined that the reduction amount is greater than the fourth threshold value and less than or equal to the fifth threshold value, then determining that the rinsing water level is less than the target washing water level, and the water volume corresponding to the rinsing water level is reduced by a fourth value compared with the water volume corresponding to the target washing water level; if it is determined that the reduction amount is greater than the fifth threshold value and less than or equal to the sixth threshold value, then determining that the rinsing water level is less than the target washing water level, and the water volume corresponding to the rinsing water level is reduced by a fifth value compared with the water volume corresponding to the target washing water level.

[0088] The fourth threshold is smaller than the fifth threshold, and the fifth threshold is smaller than the sixth threshold.

[0089] It should be noted that the fourth threshold value may be 20%, the fifth threshold value may be 30%, the sixth threshold value may be 40%, the fourth value may be 5 liters (L), and the fifth value may be 10L.

[0090] For example, when the sound amplitude is less than a preset amplitude threshold, it is determined that the washing water level is high during the laundry load wash process and no water replenishment is required. After the washing stage, the rinse stage begins. Under normal circumstances, the rinse water level is one level higher than the washing water level (i.e., the rinse water level is greater than the wash water level). In this case, since the wash water level is high, the rinse water level can be automatically controlled according to the recorded target wash water level. When the sound amplitude decreases to 20% of the preset amplitude threshold, the washing machine controller automatically controls the rinse water level to equal the target wash water level according to a preset program, and does not execute the inherent program flow of the rinse water level exceeding the wash water level. When the sound amplitude decreases to 30% of the preset amplitude threshold, the washing machine controller automatically controls the rinse water level to be 5L less than the target wash water level according to a preset program, and does not execute the inherent program flow of the rinse water level exceeding the wash water level. When the sound amplitude decreases to 40% of the preset amplitude threshold, the washing machine controller automatically controls the rinse water level to be 10L less than the target wash water level according to a preset program, and does not execute the inherent program flow of the rinse water level exceeding the wash water level.

[0091] In this embodiment, the sound amplitude of the washing stage is detected in real time by an audio sensor, and then the controller of the washing equipment automatically replenishes water to adjust the washing water level in the washing stage or automatically controls the rinsing water level in the rinsing stage according to the increase or decrease in the sound amplitude relative to the preset amplitude threshold, thereby ensuring the accuracy of the washing water level and the rinsing water level and saving water resources.

[0092] In one or more possible embodiments, Figure 3As shown, after detecting the sound amplitude in the washing stage, the audio sensor provided in the washing device 301 can also send the sound amplitude to the cloud server 302, and the cloud server determines the increase or decrease in the sound amplitude relative to the preset amplitude threshold, and controls the washing device to automatically replenish water and adjust the washing water level in the washing stage or automatically control the rinsing water level in the rinsing stage according to the increase or decrease.

[0093] In this embodiment, the cloud server processes relevant data of sound amplitude to control the water level of the washing equipment, thereby reducing the computing resources of the original controller of the washing equipment and improving the operating efficiency of the washing equipment.

[0094] Figure 4 It is a schematic diagram of the internal structure of a washing device shown in an exemplary embodiment of the present invention.

[0095] like Figure 4 As shown, the washing device provided in this embodiment includes: an audio sensor 401 and a controller 402;

[0099] Furthermore, the controller is specifically configured to:

[0100] determining the amount of water to be replenished according to the increment;

[0103] If the increment is less than or equal to a first threshold, determining the replenished water amount to be a first value;

[0104] If the increment is greater than the first threshold and less than or equal to the second threshold, determining the replenishment water amount to be the second value;

[0105] If the increment is greater than the second threshold and less than or equal to the third threshold, determining the replenished water amount to be the third value;

[0106] The first threshold is smaller than the second threshold, and the second threshold is smaller than the third threshold.

[0107] Furthermore, the first value, the second value and the third value are all smaller than the upper limit of the water capacity of the washing equipment.

[0108] Furthermore, the controller is further configured to:

[0109] If the sound amplitude is less than the preset amplitude threshold, determining a decrease in the sound amplitude relative to the preset amplitude threshold;

[0110] According to the reduction amount, the rinsing water level of the washing device in the rinsing stage is controlled.

[0111] Furthermore, before determining whether the sound amplitude is greater than a preset amplitude threshold, the controller is further configured to:

[0112] The target washing water level of the washing equipment during the washing stage is recorded.

[0113] Furthermore, the controller is specifically configured to:

[0114] When it is detected that the current operation phase of the washing equipment enters the rinsing phase from the washing phase,

[0115] If it is determined that the reduction amount is less than or equal to a fourth threshold, determining that the rinsing water level is equal to the target washing water level;

[0116] If it is determined that the reduction amount is greater than the fourth threshold and less than or equal to the fifth threshold, it is determined that the rinsing water level is less than the target washing water level, and the water volume corresponding to the rinsing water level is less than the water volume corresponding to the target washing water level by a fourth value;

[0117] If it is determined that the reduction amount is greater than the fifth threshold and less than or equal to the sixth threshold, it is determined that the rinsing water level is less than the target washing water level, and the water volume corresponding to the rinsing water level is less than the water volume corresponding to the target washing water level by a fifth value;

[0118] The fourth threshold is smaller than the fifth threshold, and the fifth threshold is smaller than the sixth threshold.
