Technical Field

[0001] This application relates to the field of garment washing and drying technology, and in particular to a washing and drying control method, apparatus, washing and drying equipment, storage medium, and computer program product. Background Technology

[0002] With the improvement of living standards, washing machines have become an indispensable household appliance. Among them, front-loading washing machines are more widely used than top-loading washing machines due to their greater water conservation. When washing clothes, front-loading washing machines typically use the rotation of the inner drum driven by a motor, along with the lifting ribs on the inner drum wall, to lift and tumble the soaked clothes against the drum wall or the lifting ribs, simulating the principle of beating clothes to achieve cleaning. When drying clothes in a front-loading washing machine, the clothes are also lifted in the same way to allow hot air to fully contact the clothes for drying.

[0003] However, in current drum washing machines, how to effectively identify the state of clothes being lifted during the washing and drying process in order to improve the efficiency of washing and drying is an urgent problem to be solved. Summary of the Invention

[0020] When the clothing trajectory image matches the lower boundary clothing trajectory image, the motor speed of the washing and drying equipment is increased by a second preset speed range so that the lifting state of the clothing meets the target lifting state.

[0021] In one embodiment, acquiring the ultrasonic reflection waveform of clothes in the washer-dryer as they rise with the inner drum includes:

[0022] The ultrasonic generator of the washing and drying equipment is controlled to emit ultrasonic signals to the inner tub at a preset frequency.

[0023] The ultrasonic reflection waveform fed back by the ultrasonic receiver of the washing and drying equipment is received.

[0024] Secondly, this application also provides a washing and drying control device, the device comprising:

[0025] The acquisition module is used to acquire the ultrasonic reflection waveform of the clothes in the washing and drying equipment as they are lifted by the inner drum after the washing and drying equipment is started and running.

[0026] The integration module is used to integrate the ultrasonic reflection waveforms to obtain a clothing trajectory image;

[0027] The adjustment module is used to adjust the motor speed of the washing and drying equipment so that the lifting state of the clothes meets the target lifting state when the lifting state of the clothes is determined to be not in accordance with the lifting state of the clothes trajectory image.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] The washing and drying control method provided in this application embodiment can be applied to, for example... Figure 1The application environment shown is specifically a washer-dryer. The control system 102 of the washer-dryer is connected to the motor 104 and ultrasonic component 106 of the washer-dryer. The control system 102 controls the operation of the motor 104. Specifically, after the washer-dryer starts running, the control system 102 acquires the ultrasonic reflection waveforms of the clothes as they rise with the inner tub from the ultrasonic component 106; it integrates these ultrasonic reflection waveforms to obtain a clothing trajectory image; if the clothing trajectory image indicates that the rising state of the clothes does not meet the target rising state, it adjusts the motor speed of the motor 104 of the washer-dryer to ensure that the rising state of the clothes meets the target rising state. It can be understood that the control system 102 for controlling the motor of the washer-dryer can be a controller directly installed inside the washer-dryer or an external control system based on wireless communication.

[0048] In one embodiment, such as Figure 2 As shown, a washing and drying control method is provided, which is applied to... Figure 1 The control system 102 in the example is used as an example, including the following S200 to S600, wherein:

[0049] S200: After the washing and drying equipment is started, the ultrasonic reflection waveform of the clothes in the washing and drying equipment is acquired during the process of the clothes being lifted by the inner drum.

[0050] The start-up of the washer-dryer can be initiated by the processor upon receiving a start command from the user via an interactive device, which then controls the motor of the washer-dryer to start. The initial motor speed can be either the default speed or a speed determined by the user-defined washer-dryer program set via the interactive device, followed by motor start-up control at that speed. The washer-dryer program can include washing and drying programs. The user can select the appropriate washing and drying programs based on the type of clothing via the interactive device. This process is completed before the washer-dryer starts operating, and the start command is issued accordingly. The specific content of the washing and drying programs selected by the user based on the type of clothing can be determined using methods conventionally practiced by those skilled in the art and will not be detailed in this application.

[0051] Specifically, the inner tub of the washer-dryer is connected to the motor via a belt or directly, and the inner tub rotates under the drive of the motor. The space inside the inner tub of the washer-dryer is the washing and drying space. The clothes to be washed and dried are placed in the washing and drying space, and are lifted up by the force of the inner tub's rotation and the lifting ribs set on the inner wall of the inner tub.

[0052] Furthermore, the ultrasonic reflection waveform is the waveform formed by the ultrasonic waves reflected back from the clothes in the inner tub during the washing and drying process, which can be used to form the trajectory of the clothes during this process. It can be understood that, in one embodiment, acquiring the ultrasonic reflection waveform of the clothes during the process of the clothes being lifted by the inner tub in the washing and drying equipment includes: controlling the ultrasonic generator of the washing and drying equipment to emit ultrasonic signals to the inner tub at a preset frequency; and receiving the ultrasonic reflection waveform fed back by the ultrasonic receiver of the washing and drying equipment. Specifically, the ultrasonic generator is connected to the control system, and after the control system sets the output frequency of the ultrasonic generator to a preset frequency, it immediately begins to emit ultrasonic waves into the inner tub at the preset frequency. During the process of the clothes being lifted by the inner tub, the reflected ultrasonic waves are received by the ultrasonic receiver and then fed back to the control system. The ultrasonic generator can be implemented using an ultrasonic transducer, and the ultrasonic receiver can be implemented using an ultrasonic sensor. In addition, to record the trajectory of the clothes during the process of being lifted by the inner tub in the most accurate way, the ultrasonic component is preferably set at a position facing the cross-section of the washing and drying equipment towards the inner tub, such as on the door or door seal of the washing and drying equipment, or it can be set at other positions in the washing and drying equipment, as long as it can achieve the acquisition of the ultrasonic reflection waveform of the clothes during the process of being lifted by the inner tub.

[0053] It is understandable that the washer-dryer will start operating and enter different working modes based on the different function activation commands received from the user through the interactive device. For example, if the user commands that the clothes need to be washed separately, the washer-dryer will start operating and enter the washing mode, and follow the washing program selected by the user; if the user commands that the clothes need to be dried separately, the washer-dryer will start operating and enter the drying mode, and follow the drying program selected by the user; if the user commands that the clothes need to be washed first and then dried, the washer-dryer will start operating and enter the washing mode first, and then directly enter the drying mode after the washing program is completed, and follow the drying program selected by the user.

[0054] S400: Integrates the images of each ultrasonic reflection waveform to obtain an image of the clothing trajectory.

[0055] It can be understood that each ultrasonic reflection waveform received by the ultrasonic receiver represents the position of the clothing in the inner tub after being lifted up by the inner tub, reflecting ultrasonic waves. Correspondingly, based on multiple consecutively received ultrasonic reflection waveforms, the movement trajectory of the clothing after being lifted up by the inner tub can be obtained. Specifically, after receiving each ultrasonic reflection waveform, the control system can integrate the ultrasonic reflection waveforms in the order of reception, stitching them together frame by frame to obtain an image of the clothing trajectory.

[0056] In this embodiment, a clothing trajectory image represents the process of clothing starting from the bottom of the inner tub, rising with the inner tub, and then falling back to the bottom of the inner tub. This clothing trajectory image can be obtained by cropping after image integration, or by directly integrating the ultrasonic reflection waveforms within a preset time period. The preset time period represents the approximate length of time it takes for the clothing to start from the bottom of the inner tub, rise with the inner tub, and then fall back to the bottom of the inner tub.

[0057] S600: If the lifting state of the clothes does not meet the target lifting state according to the clothing trajectory image, adjust the motor speed of the washing and drying equipment so that the lifting state of the clothes meets the target lifting state.

[0058] The target lifting state refers to the lifting state in which clothes achieve the best washing or drying effect. This can be understood as follows: when clothes are washed in this lifting state, they are tossed up by the rotating inner drum and then fall, impacting the inner wall of the drum with maximum force; when clothes are dried in this lifting state, they are lifted by the rotating inner drum and, under the action of hot air, can fully unfold and dry to the maximum extent. It can be understood that the target lifting state in washing mode and the target lifting state in drying mode can be the same or different. If different target lifting states are set, the corresponding target lifting state must be selected according to the current operating mode of the washer-dryer before comparison.

[0059] Specifically, if the lifting state of the clothes, as determined by the clothing trajectory image, does not meet the target lifting state, it indicates that the current motor speed of the washer-dryer is not achieving the optimal washing or drying effect and needs adjustment. Adjusting the motor speed to ensure the clothes are lifted to the target lifting state can be done by increasing or decreasing the motor speed, depending on the state of the clothing trajectory image.

[0060] The above-mentioned washing and drying control method acquires the ultrasonic reflection waveforms of the clothes as they are lifted by the inner drum after the washing and drying equipment starts running; integrates the ultrasonic reflection waveforms to obtain a clothing trajectory image; if the lifting state of the clothes does not meet the target lifting state based on the clothing trajectory image, the motor speed of the washing and drying equipment is adjusted to make the lifting state of the clothes meet the target lifting state. By effectively identifying the lifting state of the clothes during the operation of the drum washing machine in real time, the motor speed is adjusted to ensure that the clothes are continuously in the target lifting state, so that the clothes are fully tumbled against the inner wall of the inner drum after being lifted, thereby improving the efficiency of washing and drying clothes.

[0061] It is understood that before S600, there is also S500: determining whether the lifting state of the clothing meets the target lifting state based on the clothing trajectory image. In one embodiment, such as... Figure 3 As shown, S500 includes S520 to S540:

[0062] S520: If the clothing trajectory image matches the target clothing trajectory image, determine that the lifting state of the clothing satisfies the target lifting state.

[0063] The target clothing trajectory image is obtained by integrating the ultrasonic reflection waveforms of the clothing as it is lifted by the inner tub in the target lifting state. For example... Figure 4 As shown, when clothes are washed along this trajectory, they are tossed up by the rotation of the inner tub and then fall, striking the inner wall of the tub with maximum force. When clothes are dried along this trajectory, they are lifted by the rotation of the inner tub and, under the action of hot air, can fully unfold and dry to the maximum extent. It can be understood that the target clothing trajectory image and its corresponding target tossing state can be determined in advance through experiments. By measuring parameters such as the landing point and tumbling force of the clothes on the inner wall of the tub under different clothing trajectory images and tossing states, the clothing trajectory image under the tossing state with the greatest tumbling force can be determined as the target clothing trajectory image for the washing mode. Furthermore, the target trajectory image for the drying mode can be the same as that for the washing mode, or it can be determined in advance through experiments as well.

[0064] Specifically, when the currently integrated clothing trajectory image matches the target clothing trajectory image, it can be determined that the current lifting state of the clothing meets the target lifting state. Here, "clothing trajectory image matches the target clothing trajectory image" can mean that the clothing trajectory image and the target clothing trajectory image are completely identical, or that the difference between the clothing trajectory image and the target clothing trajectory image is within an allowable range.

[0065] S540: If the clothing trajectory image does not match the target clothing trajectory image, it is determined that the lifting state of the clothing does not meet the target lifting state. Correspondingly, if the currently actually integrated clothing trajectory image is inconsistent with the target clothing trajectory image, or if the difference between the currently actually integrated clothing trajectory image and the target clothing trajectory image is not within the allowable difference range, it is determined that the current lifting state of the clothing does not meet the target lifting state.

[0066] In one embodiment, such as Figure 5 As shown, S600 adjusts the motor speed of the washing and drying equipment to ensure that the clothes are lifted to a target lifting state, including S620 to S640, wherein:

[0067] S620: When the falling curve of the clothing trajectory image is inside the falling curve of the target clothing trajectory image, control the motor speed of the washing and drying equipment to increase so that the lifting state of the clothing meets the target lifting state.

[0068] The falling curve of the clothing trajectory image represents the portion of the clothing falling from the bottom of the inner drum after being lifted to its highest point, influenced by gravity. It can be understood that when the falling curve of the clothing trajectory image obtained from the current ultrasonic reflection waveform integration is inside the falling curve of the target clothing trajectory image, it indicates that the clothing has not yet reached its highest point before beginning to fall. Correspondingly, the motor speed of the washer-dryer needs to be increased to raise the clothes to a higher position before they fall, thus satisfying the target lifting state.

[0069] Specifically, there are multiple ways to control the increase of the motor speed in a washer-dryer. One approach is to gradually increase the motor speed in preset steps while simultaneously acquiring real-time images of the clothing trajectory until it matches the target clothing trajectory, indicating that the clothing's lifting state meets the target lifting state. Alternatively, one could first acquire the height difference between the falling curve of the clothing trajectory image and the falling curve of the target clothing trajectory image, analyze this height difference to determine the motor speed adjustment amount, and then control the increase of the washer-dryer motor speed according to this adjustment amount, ensuring the clothing's lifting state meets the target lifting state.

[0070] S640: When the falling curve of the clothing trajectory image is outside the falling curve of the target clothing trajectory image, the motor speed of the washing and drying equipment is reduced so that the lifting state of the clothing meets the target lifting state.

[0071] Conversely, if the falling curve of the clothing trajectory image obtained by integrating the current ultrasonic reflection waveform is outside the falling curve of the target clothing trajectory image, it indicates that the clothing has reached its highest point and continues to rotate upward along the inner wall of the drum, without falling. Correspondingly, it is necessary to control the motor speed of the washing and drying equipment to reduce the speed of the drum so that the clothing starts to fall as soon as it reaches its highest point, thus satisfying the target lifting state.

[0072] Specifically, there are several ways to control the reduction of the motor speed in a washer-dryer. One approach is to gradually reduce the motor speed in preset steps while simultaneously acquiring real-time images of the clothing trajectory until it matches the target clothing trajectory, indicating that the clothing's lifting state meets the target lifting state. Alternatively, one could first acquire the height difference between the falling curve of the clothing trajectory image and the falling curve of the target clothing trajectory image, analyze this height difference to determine the motor speed adjustment amount, and then control the reduction of the washer-dryer's motor speed according to this adjustment amount, ensuring the clothing's lifting state meets the target lifting state.

[0073] It is understandable that, prior to S620 or S640, if the clothing trajectory image indicates that the clothing is not lifted by the inner drum's rotational force, or if the clothing is continuously rotating against the inner wall of the inner drum, the lifting state of the clothing can be quickly adjusted to near the target lifting state by significantly adjusting the motor speed of the washer-dryer. This reduces the number of times the motor speed needs to be adjusted, improves the efficiency of motor speed adjustment, and reduces adjustment time.

[0074] In one embodiment, such as Figure 6 As shown, S600 also includes S610: when the clothing trajectory image matches the boundary clothing trajectory image, the motor speed of the washing and drying equipment is controlled to change by a preset speed range so that the lifting state of the clothing meets the target lifting state.

[0075] The boundary clothing trajectory image is used to represent the state where the clothing is not lifted by the rotational force of the inner tub, or where the clothing continues to rotate while adhering to the inner wall of the inner tub. In one embodiment, the boundary clothing trajectory image includes an upper boundary clothing trajectory image and a lower boundary clothing trajectory image. Correspondingly, the upper boundary clothing trajectory image is the clothing trajectory image in the lifted state where the clothing continues to rotate while adhering to the inner wall of the inner tub, for example... Figure 7 As shown. The lower boundary clothing trajectory image, that is, the clothing trajectory image when the clothing is in a lifted state without being lifted by the rotational force of the inner tub, for example. Figure 8 As shown.

[0076] Specifically, the preset rotational speed range represents the amount by which the motor speed of the washer-dryer needs to be adjusted when the clothes change from the boundary clothing trajectory image state to the target clothing trajectory image state. Correspondingly, by controlling the motor speed of the washer-dryer to change directly according to this preset rotational speed range, the lifting state of the clothes can be made to meet the target lifting state.

[0077] In one embodiment, such as Figure 9 As shown, S610 includes S612 to S614, wherein:

[0078] S612: When the clothing trajectory image matches the upper boundary clothing trajectory image, the motor speed of the washer-dryer is reduced by a first preset speed range to ensure that the lifting state of the clothing meets the target lifting state. Specifically, the first preset speed range represents the amount by which the motor speed of the washer-dryer needs to be adjusted when the clothing changes from the upper boundary clothing trajectory image state to the target clothing trajectory image state. The motor speed of the washer-dryer can be directly reduced by the first preset speed range to ensure that the lifting state of the clothing meets the target lifting state.

[0079] S614: When the clothing trajectory image matches the lower boundary clothing trajectory image, the motor speed of the washer-dryer is increased by a second preset speed increment to ensure that the lifting state of the clothing meets the target lifting state. Specifically, the second preset speed increment represents the amount by which the motor speed of the washer-dryer needs to be adjusted when the clothing changes from the lower boundary clothing trajectory image state to the target clothing trajectory image state. The motor speed of the washer-dryer can be directly increased by the second preset speed increment to ensure that the lifting state of the clothing meets the target lifting state.

[0080] It is understood that the values ​​of the first preset speed range and the second preset speed range are not fixed and can be determined based on data from actual experiments. Furthermore, if, after adjusting the first and second preset speed ranges, the lifting state of the clothes still does not meet the target lifting state, the motor speed of the washer-dryer can be further adjusted according to steps S620 or S640 until the lifting state of the clothes meets the target lifting state.

[0081] To facilitate a better understanding of the above air conditioning control method, a detailed explanation is provided below with reference to specific embodiments.

[0082] The washing method of a drum washing machine involves using the rotation of the drum to lift and tumble the soaked clothes against the lifting ribs inside the drum, creating a beating effect to clean the clothes. Similarly, drying in a drum washing machine requires lifting the clothes to allow hot air to fully contact them for faster drying. Therefore, recognizing and controlling the landing point and the shape of the clothes during washing or drying has a positive effect on the washing and drying results. Currently, most methods for recognizing clothing trajectories use built-in cameras to observe the movement of the clothes. However, when there is no light inside the drum or the lighting is poor, the camera may have difficulty recognizing the clothing trajectories due to brightness issues. Furthermore, since users do not need to observe the image inside the drum in real time, the practicality of using a camera to observe the clothing trajectories in real time is not high.

[0083] Based on this, this application proposes a method for identifying clothing trajectories using ultrasound, and continuously adjusting the speed of the drum drive motor by comparing it with the system's optimal trajectory, so that the clothes can achieve the optimal trajectory and landing point during washing, drying or care, thereby achieving the best washing or drying effect and realizing intelligent washing and drying of clothes.

[0084] Specifically, ultrasound is a high-frequency sound wave with good directionality. The principle of ultrasound imaging is to use an ultrasound generator to emit ultrasound waves to scan an object. Taking advantage of the different reflection intensities of different media, an ultrasound receiver receives, processes, and feeds the reflected signals back to the main control system to achieve an imaging effect. When the ultrasound generator emits at a certain frequency, real-time imaging can be achieved through image synthesis by the control system.

[0085] The washing process involves the inner drum rotating and lifting the wet clothes using ribs. After reaching a certain height, the clothes are thrown out and fall back into the drum, creating a tumbling effect that washes the clothes. The drying process involves hot, dry air blowing onto the tumbled clothes to remove moisture. Therefore, the tumbling process is crucial. The optimal trajectory for the clothes is that they are thrown out as the drum rotates, thoroughly tumbled during washing, and fully unfolded after being lifted and blown out during drying (care). If the drum speed is too slow or the clothes are too heavy after absorbing water, the clothes will roll continuously in the direction of rotation and cannot be lifted. Conversely, if the drum speed is too fast or the clothes are light, they will simply stick to the drum and rotate, failing to achieve optimal washing or drying results.

[0086] This application utilizes the characteristics of real-time ultrasonic imaging. An ultrasonic generator and receiver are placed on the washing machine door. During washing and drying, the generator emits sound waves at a specific frequency. Through processing by the receiver and control system, the trajectory of the clothes can be analyzed in real time, and the motor speed and drum speed can be adjusted to achieve the optimal lifting height, shape, and landing point for the clothes. When it is detected that the clothes cannot be lifted during washing or drying, the drum speed is increased, causing the clothes to be lifted under higher centrifugal force. If, during washing, the landing point is not on the lifting ribs after lifting, the drum speed is adjusted based on the left or right of the landing point on the lifting ribs to adjust the landing point of the clothes within the drum. By continuously adjusting the motor speed, the optimal condition of the clothes during washing and drying is achieved, realizing intelligent washing and drying. Ultrasonic imaging does not require good lighting conditions and can achieve real-time imaging even in dimly lit working environments.

[0087] like Figure 10 The diagram shows the workflow of an ultrasonic transceiver, including steps 101 to 103:

[0088] 101: An ultrasonic generator emits scanning ultrasonic waves intermittently into the drum at a certain frequency when washing, drying, or caring for clothes in a washing machine.

[0089] 102: The other end is an ultrasonic receiver, which receives the sound waves reflected inside the drum and feeds the sound waves back to the ultrasonic control system in a timely manner (which can be the same as the washing machine control system).

[0090] 103: After receiving the waveform feedback from the receiver, the control system processes the waveform and generates a corresponding image. Based on the images generated from waveforms of a certain frequency, a real-time trajectory is synthesized. According to the trajectory image, the speed of the drum drive motor is adjusted in real time to optimize the trajectory of the clothes, ensuring that the washed clothes fall on the lifting ribs, achieving the best washing and drying effect.

[0091] like Figure 11 The diagram shows the workflow of the washing and drying control method provided in this application under washing mode, including steps 201 to 213:

[0092] 201: Users select the washing program based on the type of clothing;

[0093] 202: The washing machine's control module will select the washing parameters according to the preset program and complete preparations such as weighing, water intake, and detergent dispensing;

[0094] 203: The motor drives the drum to rotate according to the preset parameters, and the washing of clothes begins;

[0095] 204: The ultrasonic control system 206 drives the ultrasonic generator to work and scan the clothes inside the drum at a set frequency;

[0096] 205: The ultrasonic receiver receives the waveform reflected by the clothes in the drum, sorts it out, and transmits it to the control system 206;

[0097] 207: The control system 206 receives various waveforms, integrates them into an image, and synthesizes them into a trajectory diagram of the clothing;

[0098] 208: Based on the trajectory diagram, determine whether the clothing is lifted by the roller lifting ribs?

[0099] 209: If 208 is incorrect, it means that the drum speed is too low and the clothes cannot be lifted by the centrifugal force of the drum. Therefore, the drum speed needs to be increased appropriately to lift the clothes.

[0100] 210: If 208 is true, then determine whether the garment is constantly rotating against the sleeve?

[0101] 211: If 210 is true, it means that the drum speed is too high and the centrifugal force on the clothes is too great. The drum speed needs to be reduced appropriately so that the clothes will not keep rolling against the drum.

[0102] 212: If 210 is not true, then determine whether the washing process is complete after a period of time.

[0103] If 212 is not correct, it means the clothes are not finished washing, and the drum speed will be adjusted again.

[0104] 213: If 212 is true, it proves that the washing process of the clothes has been completed, and the washing process ends.

[0105] like Figure 12 The diagram shows the workflow of the washing and drying control method provided in this application under drying mode, including steps 301 to 313:

[0106] 301: The user selects the drying (care) program based on the type of clothing, or the system selects the drying program based on the washing data from the previous stage;

[0107] 302: The washing machine's control module will select drying (care) parameters according to the preset program and complete preparatory work such as weighing;

[0108] 303: During drying, the drum rotates at a set speed to begin drying (care for) the clothes;

[0109] 304: The ultrasonic control system 306 drives the ultrasonic generator to work and scan the clothes inside the drum at a set frequency;

[0110] 305: The ultrasonic receiver receives the waveform reflected by the clothes in the drum, sorts it out, and transmits it to the control system 306;

[0111] 307: The control system 306 receives various waveforms, integrates them into an image, and synthesizes them into a trajectory diagram of the clothing;

[0112] 308: Based on the trajectory diagram, determine whether the clothing is lifted by the roller lifting ribs?

[0113] 309: If 308 is incorrect, it means that the drum speed is too low and the clothes cannot be lifted by the centrifugal force of the drum. In this case, the drum speed needs to be increased appropriately so that the clothes can be lifted.
