[0002] After dehydration, clothes in a washing and drying machine often cling to the walls of the drum. If the machine goes directly into the drying cycle, the clothes clinging to the walls are unable to reach the hot air blown into the drum, resulting in uneven drying. Current washing and drying machines cannot accurately detect the clinging of clothes, which can lead to poor drying results, long drying times, and a poor user experience. Summary of the Invention

[0007] Determining a wind speed difference between the inlet wind speed and the outlet wind speed;

[0008] Determining the magnitude of the wind speed difference and a set wind speed difference;

[0009] When the wind speed difference is less than the set wind speed difference, stopping the drying process;

[0010] When the wind speed difference is greater than or equal to the set wind speed difference, a wind speed change rate of the outlet wind speed is determined, and the drying time of the drying program is adjusted according to the wind speed change rate.

[0011] In some embodiments, adjusting the drying time of the drying process according to the wind speed change rate includes:

[0012] Determining the magnitude of the wind speed change rate and a set wind speed change rate;

[0013] When the wind speed change rate is less than the set wind speed change rate, the drying time of the drying program is shortened.

[0014] In some embodiments, when the wind speed difference is less than the set wind speed difference, the washer-dryer is also controlled to execute a shaking program, and / or a prompt message is sent to the user.

[0015] In some embodiments, before entering the drying process and after completing the dehydration process of the washing process, the control method includes:

[0016] Obtain the weight and eccentricity of the clothes in the laundry treatment drum;

[0017] The subsequent operation program of the washing and drying device is determined according to the weight of the clothes and the eccentricity value.

[0018] In some embodiments, determining a subsequent operation procedure of the washer-dryer according to the laundry weight and the eccentricity value includes:

[0019] Determining the difference between the weight of the clothes and the set weight;

[0020] When the weight of the clothes is less than or equal to the set weight, controlling the washing and drying device to enter a drying program;

[0021] When the weight of the clothes is greater than the set weight, the eccentricity change rate of the eccentricity value is determined, and the subsequent operation program of the washing and drying device is determined according to the eccentricity change rate.

[0022] In some embodiments, determining a subsequent operation procedure of the washer-dryer according to the eccentricity change rate includes:

[0026] In some embodiments, when the eccentricity change rate is less than or equal to the set eccentricity change rate, in the subsequent drying program, the steps of obtaining the inlet wind speed and outlet wind speed of the drying air of the clothing processing drum and regulating the drying process according to the inlet wind speed and the outlet wind speed are performed.

[0027] The second aspect of the present invention proposes a control device, which includes one or more processors and a non-temporary computer-readable storage medium storing program instructions.

[0039] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0040] Figure 1 This is a control flow diagram of a washing and drying device according to an exemplary embodiment. Figure 1 , refer to Figure 1 , the control method comprises the following steps:

[0041] S11 . In a drying process, obtaining the inlet and outlet speeds of the drying air of the clothes processing drum.

[0042] In this embodiment, during the drying process of clothes, the drying system of the washing and drying device supplies drying air into the clothes processing drum, and then further determines the distribution state of the clothes in the clothes processing drum by obtaining the air inlet speed and air outlet speed of the clothes processing drum. In one example, the washing and drying device further includes an outer drum, and the clothes processing drum is coaxially arranged in the outer drum and can rotate in the outer drum. An air inlet and an air outlet are provided on the outer drum, the air outlet end of the air supply duct of the drying system of the washing and drying device is provided at the air inlet, and the air inlet end of the return air duct of the drying system is provided at the air outlet, and the air supply duct inputs drying air into the clothes processing drum through the air inlet. Exemplarily, the air supply duct inputs drying air of a constant wind speed into the clothes processing drum through the air inlet, and a wind speed detection device is provided at the air outlet, and the wind speed detection device detects the wind speed of the outlet. In this embodiment, the wind speed of the outlet can be a wind speed detected in real time, or the wind speed of the outlet can be detected once every set time, or it can be the average wind speed of multiple wind speeds detected continuously.

[0043] S12. Regulating the drying process of the drying program according to the inlet air speed and the outlet air speed.

[0044] In this embodiment, after obtaining the inlet and outlet air speeds, the distribution state of the clothing within the laundry treatment drum can be determined based on the inlet and outlet air speeds. Examples of distribution states include a clinging state and a loose state. Depending on the distribution state of the clothing within the laundry treatment drum, the inlet and outlet air speeds vary differently. For example, when the clothing within the drum is clinging to the wall, cavities form within the drum, the area of ​​clothing exposed by the hot air is small, and the inlet and outlet air speeds vary little. When the clothing within the drum is loose, no cavities form within the drum, the area of ​​clothing exposed by the hot air is large, and the inlet and outlet air speeds vary significantly. In one example, hot air is delivered to the laundry treatment drum at a constant speed within the drying system. The outlet air speeds corresponding to different states of clothing within the drum vary. Therefore, the distribution state of the clothing within the laundry treatment drum can be determined based on the obtained inlet and outlet air speeds.

[0045] Figure 2 This is a control flow diagram of a washing and drying device according to an exemplary embodiment. Figure 2 , refer to Figure 2 The steps of regulating the drying process of the drying program according to the inlet air speed and the outlet air speed include:

[0046] S21. Determine the wind speed difference between the inlet wind speed and the outlet wind speed;

[0047] S22, determining the magnitude of the wind speed difference and the set wind speed difference;

[0048] S23. When the wind speed difference is less than the set wind speed difference, stop the drying process; when the wind speed difference is greater than or equal to the set wind speed difference, determine the wind speed change rate of the outlet wind speed and adjust the drying time of the drying process according to the wind speed change rate.

[0049] In this embodiment, after entering the drying cycle, the drying system introduces dry hot air into the laundry drum. After the hot air passes through the laundry, it is mixed with moisture and discharged from the laundry drum. After obtaining the inlet and outlet air speeds of the laundry drum, it is necessary to determine the speed difference between the inlet and outlet air speeds. This is because after the hot air enters the laundry drum at a constant speed, the area of ​​the laundry contacted by the hot air will affect the outlet air speed. For example, if the laundry in the laundry drum is loose, the area of ​​the laundry contacted by the hot air is large. In this case, the outlet air speed is low, and the speed difference between the inlet and outlet air speeds is large. If the laundry in the laundry drum is clinging to the wall, the area of ​​the laundry contacted by the hot air is small. In this case, the outlet air speed is high, and the speed difference between the inlet and outlet air speeds is small. After determining the speed difference between the inlet and outlet air speeds, the speed difference between the inlet and outlet air speeds is compared with the set speed difference. When the speed difference between the inlet and outlet air speeds is greater than or equal to the set speed difference, the clothes are evenly distributed in the laundry processing drum, no cavities are formed in the laundry processing drum, and the hot air contacts a large area of ​​the clothes, and the clothes are determined to be in a dispersed state. When the speed difference between the inlet and outlet air speeds is less than the set speed difference, the clothes are severely stuck to the wall of the laundry processing drum, cavities are formed in the laundry processing drum, and the hot air contacts a small area of ​​the clothes, and the clothes are determined to be in a stuck state.

[0050] Specifically, if it is determined that the clothes are in a state of sticking to the wall, the drying process is stopped. If it is determined that the clothes are in a loose state, the wind speed change rate of the air outlet speed is determined, and the drying time of the drying process is adjusted based on the wind speed change rate. If the clothes are determined to be in a state of sticking to the wall, it means that the clothes in the clothes processing drum are seriously sticking to the wall. At this time, the drying process needs to be stopped to prevent the clothes on the outer layer from being over-dried due to continued high-temperature airflow, thereby damaging the outer layer clothes. In one example, after stopping the drying process, a shaking process can be further performed to shake the clothes loose, and / or a prompt message can be sent to the user to remind the user that the clothes are seriously sticking to the wall. After the shaking process ends, the user can choose to continue the drying process or directly end the drying process. If the clothes are determined to be in a loose state, the wind speed change rate of the air outlet speed needs to be further determined to judge the drying status of the clothes in the clothes processing drum, and then the drying time of the drying process is adjusted based on the wind speed change rate. The wind speed change rate is the rate of change of the air outlet speed within a first set time period. The first setting time can be set according to the material of the clothes being dried. For example, for silk clothes with low water absorption, the moisture content of the clothes changes quickly. At this time, the first setting time should be set to a shorter time interval, such as 5s or 10s; for cotton clothes with high water absorption, the moisture content of the clothes changes slowly. At this time, the first setting time should be set to a longer time interval, such as 30 or 40s.

[0051] Figure 3 This is a control flow diagram of a washing and drying device according to an exemplary embodiment. Figure 3, refer to Figure 3 The steps of adjusting the drying time of the drying program according to the wind speed change rate include:

[0052] S31, determining the magnitude of the wind speed change rate and the set wind speed change rate;

[0053] S32. When the wind speed change rate is less than the set wind speed change rate, shorten the drying time of the drying program.

[0054] In this embodiment, after determining the wind speed change rate, the wind speed change rate is compared with the set wind speed change rate. When the wind speed change rate is greater than or equal to the set wind speed change rate, it indicates that the moisture content of the clothes is high and the hot air from the air outlet carries a large amount of water vapor, resulting in a large wind speed change rate. In this case, the current drying process is maintained until the specified drying time is reached. When the wind speed change rate is less than the set wind speed change rate, it indicates that the moisture content of the clothes is low and the hot air from the air outlet carries a small amount of water vapor, resulting in a small wind speed change rate. In this case, the drying time can be shortened, thereby improving drying efficiency.

[0055] It should be noted that the inlet wind speed, set wind speed difference and set wind speed change rate involved in this embodiment are reference values ​​obtained based on multiple tests and calculations. The corresponding reference values ​​will be taken according to the weight, material, washing mode, etc. of the clothes. For example, the inlet wind speed corresponding to cotton and linen clothes is 12m / s, the set wind speed difference range is 2.50m / s~5.20m / s, and the set wind speed change rate range is 0.12m / s. 2 ~0.31m / s 2 The corresponding wind speed for woolen clothes is 10m / s, the range of setting wind speed difference is 4.40m / s~6.30m / s, and the range of setting wind speed change rate is 0.21m / s 2 ~0.54m / s 2 The wind speed corresponding to the shirt is 8m / s, the wind speed difference is set to 2.30m / s~3.80m / s, and the wind speed change rate is set to 0.04m / s. 2 ~0.19m / s 2 .

[0056] Figure 4 This is a control flow diagram of a washing and drying device according to an exemplary embodiment. Figure 4 , refer to Figure 4 After the dehydration process of the washing program ends and before entering the drying program, the control method includes the following steps:

[0057] S41. Obtain the weight and eccentricity value of the clothes in the clothes processing tub.

[0058] In this embodiment, a washer-dryer operates according to a user-selected laundry program. The laundry program includes a washing program and a drying program. The washer-dryer can execute either the washing program or the drying program, or it can execute the washing program and the drying program sequentially. This embodiment primarily relates to a control method for a laundry processing device to sequentially execute the washing program and the drying program. After completing the dehydration process of the washing program, the washer-dryer first determines whether the drying program should be executed. If the drying program is not required, the device directly enters the subsequent washing process and ends the washing program. If the drying program is required, the weight and eccentricity of the laundry in the laundry processing drum are obtained before the drying program is executed. The laundry weight can be detected using a weighing sensor, or by measuring the motor speed under different loads, or by measuring parameters such as the time required to reach a certain speed, current, or voltage. The eccentricity value can be determined based on the motor speed fluctuation, or by using an eccentricity algorithm or torque current. Detecting the laundry weight and eccentricity value is a relatively mature technical method in the field of laundry processing devices. However, this is not the focus of this embodiment and will not be discussed in detail here.

[0059] S42. Determine the subsequent operation procedure of the washing and drying device according to the weight of the clothes and the eccentricity value.

[0060] After determining the weight and eccentricity of the laundry, the distribution state of the laundry within the laundry treatment drum can be determined based on the weight and eccentricity. For example, the distribution states of the laundry within the laundry treatment drum include a lightly loaded state, a heavily loaded, clinging state, and a heavily loaded, loose state. When the laundry treatment drum is in a lightly loaded state, the laundry is relatively light, and regardless of whether the laundry clings to the wall of the laundry treatment drum, the subsequent drying cycle allows for quick and even drying. When the laundry treatment drum is in a heavily loaded, clinging state, the laundry is heavy. During the subsequent drying cycle, the laundry clinging to the wall of the laundry treatment drum is difficult to reach with the hot air blown into the laundry treatment drum, resulting in uneven drying and prolonged drying time. When the laundry treatment drum is in a heavily loaded, loose state, although the laundry is heavy, the laundry does not cling to the wall of the laundry treatment drum. During the subsequent drying cycle, the hot air blown into the laundry treatment drum allows for even drying of the laundry. Therefore, after determining the distribution state of the clothes in the clothes processing drum, the subsequent operation program of the washing and drying device can be determined. For example, the subsequent operation program directly enters the drying program, or first executes the shaking program and then the drying program.

[0061] Figure 5 This is a control flow diagram of a washing and drying device according to an exemplary embodiment. Figure 5 , refer to Figure 5 , according to the weight of the clothes and the eccentricity value, the subsequent operation procedures of the washing and drying equipment are determined, including:

[0062] S51, determining the difference between the weight of the clothes and the set weight;

[0063] S52. When the weight of the clothes is less than or equal to the set weight, the washer-dryer is controlled to enter the drying program; when the weight of the clothes is greater than the set weight, the eccentricity change rate of the eccentricity value is determined, and the subsequent operation program of the washer-dryer is determined according to the eccentricity change rate.

[0064] In this embodiment, after obtaining the weight of the clothes, the clothes are first compared with the set weight to determine whether the clothes in the clothes processing drum are lightly loaded or heavily loaded. The set weight is the critical weight value for judging whether it is heavily loaded or lightly loaded, and is a reference value obtained through multiple tests and calculations. When the weight of the clothes is less than or equal to the set weight, it is determined that the clothes in the clothes processing drum are lightly loaded. At this time, there are fewer clothes in the clothes processing drum. At this time, regardless of whether the clothes are attached to the wall of the clothes processing drum, they can be dried quickly and evenly in the subsequent drying process, so the drying process is directly entered. When the weight of the clothes is greater than the set weight, it is determined that the clothes in the clothes processing drum are heavily loaded. At this time, it is necessary to further determine the eccentricity change rate through the obtained eccentricity value. The eccentricity change rate is the eccentricity change rate within the second set time length.

[0065] Figure 6 This is a control flow diagram of a washing and drying device according to an exemplary embodiment. Figure 6 , refer to Figure 6 The steps of determining the subsequent operation procedure of the washer-dryer according to the eccentricity change rate include:

[0066] S61, determine the size of the eccentricity change rate and the set eccentricity change rate,

[0067] S62. When the eccentricity change rate is less than or equal to the set eccentricity change rate, the washer-dryer is controlled to enter the shaking program and the drying program in sequence; when the eccentricity change rate is greater than the set eccentricity change rate, the washer-dryer is controlled to enter the drying program.

[0068] In this embodiment, since the washing and drying device shakes and distributes the clothes before dehydration, the clothes are made to stick closely to the wall of the clothes processing drum to reduce the eccentricity value. Generally speaking, the smaller the eccentricity change rate, the more evenly the clothes stick to the wall of the drum, and the tighter they stick, the larger the eccentricity change rate, the looser the clothes. Therefore, by comparing the eccentricity change rate of the clothes processing drum with the set eccentricity change rate, it is possible to further determine whether the clothes in the clothes processing drum are in a state of sticking to the wall or in a loose state under multi-load conditions. When the eccentricity change rate is less than or equal to the set eccentricity change rate, it means that there are a lot of clothes in the clothes processing drum, and the clothes are seriously stuck to the wall, and the gaps between the clothes are small. If the drying program is directly entered, the hot air cannot reach the clothes that are tightly attached to the wall of the clothes processing drum, which will cause uneven drying of the clothes and prolonged drying time. In this case, it is necessary to first enter the shaking program to shake the clothes loose, and then enter the drying program to dry the clothes, so as to improve the uniform drying effect and shorten the drying time. If the eccentricity change rate exceeds the set eccentricity change rate, the laundry is considered loose and there is no need to shake the laundry out; the drying process can be started directly to dry the laundry evenly. The set eccentricity change rate is the critical eccentricity value at which the laundry stops drying due to sticking to the wall. It is a reference value derived from multiple tests and calculations.

[0069] In some embodiments, when the eccentricity change rate is less than or equal to the set eccentricity change rate, in the subsequent drying process, the steps of obtaining the inlet and outlet wind speeds of the drying air of the clothing processing drum and regulating the drying process according to the inlet and outlet wind speeds are executed.

[0070] In this embodiment, when the eccentricity change rate is less than or equal to the set eccentricity change rate, the clothes are in a multi-load wall-adhering state in the washing drum. After the washing and drying device executes the shaking-out program, there is no need to cyclically judge the eccentricity value and execute the shaking-out program until the eccentricity change rate meets the requirements, because cyclically judging the eccentricity value and executing the shaking-out program is likely to prolong the washing time. At this time, the drying program is directly entered, and the wall-adhering state of the clothes in the clothing processing drum is further judged in the subsequent drying program, and the drying is regulated according to the judgment result.

[0071] This embodiment utilizes different data at different stages to determine and address the status of clothing within the laundry tub, improving the accuracy of determining if clothing is sticking to the wall, effectively enhancing drying efficiency and reducing drying time. Furthermore, this invention minimizes interference with the normal washing process, eliminating the need for repeated determination of wall sticking and corresponding processing. This minimizes drying time while maintaining effective drying results.
