Description

Technical Field

[0001] This invention relates to the field of washer-dryer integrated equipment technology, and in particular to a control method, electronic equipment, and washer-dryer integrated equipment. Background Technology

[0002] Traditional washing machines often leave a certain amount of moisture inside the drum after the spin cycle, especially in areas like the recessed sections where drying is difficult. This damp environment can easily breed bacteria, produce odors, and negatively impact user health. Current technology typically relies on users manually starting the drying cycle to dry the drum. However, for multi-drum washer-dryers, achieving thorough drying of multiple drums requires significant energy consumption, which contradicts users' energy-saving needs. Summary of the Invention

[0003] To overcome the technical problem in related technologies that when multiple drums in a washer-dryer combo equipment have the need for drum drying at the same time, the thorough drying effect and energy saving requirements of multiple drums cannot be simultaneously achieved, this application provides a control method, electronic equipment and washer-dryer combo equipment.

[0004] According to a first aspect of the embodiments of this application, a control method for a washer-dryer combo is provided. The washer-dryer combo includes a drying system and multiple fabric processing drums. Each of the multiple fabric processing drums has an air outlet and an air inlet. The drying system includes multiple air outlet ducts and multiple air inlet ducts. Each air outlet duct is connected to one of the air outlets, and each air inlet duct is connected to one of the air inlets. Each air outlet is equipped with a humidity detection device. The control method includes: Under the condition that the preset detection conditions are met, the humidity value of each air outlet is obtained; the preset detection conditions include at least: each fabric processing cylinder is in standby mode. The target fabric treatment cylinder that meets the conditions for cylinder drying is determined based on the outlet humidity value of each air outlet. The drying parameters are determined based on the outlet humidity value of the target fabric treatment cylinder and the number of target fabric treatment cylinders; the drying parameters include at least the drying time. Run the drum drying program and control the drying system to operate according to the drying parameters to deliver hot airflow into the drum.

[0005] In this embodiment, the drying parameters for the target fabric treatment cylinders are determined by the number of target fabrics to be dried as needed and the outlet humidity value. This ensures that all target fabric treatment cylinders are thoroughly dried while reducing the energy consumption of cylinder drying.

[0006] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, controlling the drying system to operate according to the drying parameters includes: The higher the humidity level of the outlet air, the longer the drying time; and / or, The more treatment tubes the target fabric has, the longer the drying time.

The more target fabric treatment tubes there are, the larger K is. Calculated air humidity × A × K represents the product of the calculated air humidity, A, and K. When there is only one target fabric treatment cylinder, the calculated value of the outlet humidity is the outlet humidity value of that target fabric treatment cylinder; when there are multiple target fabric treatment cylinders, the calculated value of the outlet humidity value of the multiple target fabric treatment cylinders is the average value of the outlet humidity values ​​of the multiple target fabric treatment cylinders.

The drying time is dynamically adjusted based on the drying time correction factor and the basic drying time. Among them, the higher the humidity level, the larger the drying time correction factor; the more target fabric treatment tubes, the larger the drying time correction factor. The drying parameters also include outlet air temperature and / or outlet air velocity, which increase with the increase of the humidity level of the target fabric treatment cylinder, but do not exceed the equipment safety threshold.

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0026] First, the structure of the washer-dryer combo device in this embodiment will be briefly introduced.

[0027] The washer-dryer combo equipment in this embodiment can be a top-loading impeller type washer-dryer combo equipment with the feed inlet facing upwards, or a side-loading drum type washer-dryer combo equipment. The washer-dryer combo equipment includes a housing, multiple fabric processing drums, and a drying system. The multiple fabric processing drums can be arranged side by side or vertically.

[0028] Multiple fabric processing tubes include an inner tube and an outer tube, with the inner tube rotatably disposed inside the outer tube.

[0029] Multiple fabric processing cylinders are each equipped with an air outlet and an air inlet. The hot airflow generated by the drying system enters the fabric processing cylinder through the air inlet, and the airflow inside the fabric processing cylinder flows into the drying system through the air outlet. In a specific example, the air inlet is located near the opening of the fabric processing cylinder, and the air outlet is located near the bottom of the fabric processing cylinder.

[0030] The drying system includes air ducts and a blower. The air ducts include inlet air ducts and outlet air ducts, with each outlet air duct connected to an outlet, and each inlet air duct connected to an inlet. In a specific example, the outlet air ducts include a main outlet air duct and multiple branch air ducts. The inlet ends of the multiple branch air ducts are connected to the outlets of multiple fabric processing cylinders, and the outlet ends of the multiple branch air ducts are all connected to the inlet end of the blower through the main inlet air duct. The drying system also includes a heating module, which can be heated by an electric heating device or a thermal condenser.

[0031] Furthermore, the washer-dryer combo also includes multiple humidity detection devices, each set up at the air outlet to detect the humidity of the air coming out of the outlet.

[0032] Furthermore, the washer-dryer combo also includes a microbial detection device, which is installed in the drainage path of the fabric treatment drum. For example, the bottom of the outer drum of the fabric treatment drum is provided with a drain outlet, and the microbial detection device is installed at the drain outlet to determine whether to perform sterilization treatment on the drum environment or airflow by detecting the microorganisms in the drainage of the fabric treatment drum.

[0033] Furthermore, the washer-dryer combo also includes a sterilization module, which is used to sterilize the internal environment of the fabric treatment drum and / or the airflow passing through the fabric treatment drum. This embodiment does not specifically limit the sterilization method of the sterilization module.

[0034] In one example, the sterilization module includes a steam sterilization device located on the outer cylinder. Exemplarily, the drying system is a heat pump drying system, and the steam sterilization device includes a condensate collection section and a heating section. The condensate collection section collects condensate generated by the evaporator of the heat pump drying system, and the heating section, located within the condensate collection section, heats the condensate to generate steam for sterilization. In other possible implementations, a water tank can be provided, filled with water, and then heated by a heating device located within the tank to generate steam.

[0035] In another example, the sterilization module further includes an ultraviolet (UV) sterilization device disposed within an air duct, for example, within an air inlet duct or an air outlet duct. Preferably, the sterilization device is disposed within the main air outlet duct.

[0036] The control method of the washer-dryer combo equipment in this embodiment will be described in detail below.

[0037] Reference Figure 1 The flowchart illustrates the control method for the washer-dryer combo equipment in this embodiment, which includes the following steps: S11. Under the condition that the preset detection conditions are met, obtain the humidity value of the air outlet of each air outlet; S12. Determine the target fabric treatment cylinder that meets the cylinder drying conditions based on the air humidity value of each air outlet. S13. Determine the drying parameters based on the outlet humidity value of the target fabric treatment cylinder and the number of target fabric treatment cylinders; S14. Run the drum drying program and control the drying system to operate according to the drying parameters to deliver hot airflow into the drum.

[0038] In this embodiment, it is first determined whether each fabric processing cylinder meets the preset detection conditions. The preset detection conditions include at least that each fabric processing cylinder is in a standby state. Additionally, it is necessary to ensure that the door is closed and locked, and that the filter components of the drying system are not clogged, to ensure the safety and reliability of the drying program startup and avoid ineffective operation. If at least one fabric processing cylinder is in the running stage, the detection of the outlet humidity value is not performed. If the preset detection conditions are met, the outlet humidity value of each outlet is acquired. Specifically, this is achieved by controlling the start of the air supply fan and acquiring the outlet humidity value through a humidity detection device. After determining the outlet humidity value of each outlet, it is compared with the preset humidity value. If the outlet humidity value is greater than the preset humidity value, it is determined that the environment inside the cylinder is humid, meeting the cylinder drying conditions, and the fabric processing cylinder needs to be dried. Therefore, the fabric processing cylinder with an outlet humidity value greater than the preset humidity value is the target fabric processing cylinder.

[0039] After determining the target fabric treatment cylinder, the number of target fabric treatment cylinders must be further determined. Then, the number of target fabric treatment cylinders and the outlet humidity value of the target fabric treatment cylinders are combined to determine the drying parameters. The drying parameters include at least the drying time, or the drying parameters also include the fan speed and / or drying temperature.

[0040] After determining the drying parameters, the drum drying program is run, and the heating module of the drying system is activated to deliver hot air into the drum according to the drying parameters. The temperature of the hot air is, for example, 50℃~70℃.

[0041] This embodiment can achieve thorough drying of multiple fabric processing cylinders simultaneously when multiple fabric processing cylinders have cylinder drying requirements, and reduces energy consumption during the cylinder drying process.

[0042] In one optional implementation, the drying system is controlled to operate according to drying parameters, including: The higher the outlet humidity value, the longer it takes to completely dry the fabric treatment cylinder, and therefore the longer the drying time; and / or, the more target fabric treatment cylinders there are, the more target fabric treatment cylinders the hot air flow needs to enter, the greater the heat loss, and therefore the longer the drying time.

[0043] In one alternative implementation, the drying parameters are determined by the outlet humidity value and the number of target fabric treatment cylinders, and further include: The calculated outlet humidity, the number of target fabric treatment tubes, and the drying time must meet the following requirements: Drying time = Calculated outlet humidity × A × K, where A is the base drying time. The value of A is not specifically limited and can be designed based on the performance of the drying system. For example, A = 15 minutes. The value of K is related to the number of target fabric treatment tubes; the more target fabric treatment tubes there are, the larger K becomes. Calculated outlet humidity × A × K represents the product of the calculated outlet humidity, A, and K.

[0044] When there is only one target fabric treatment cylinder, the calculated value of the outlet humidity is the outlet humidity value of that target fabric treatment cylinder; when there are multiple target fabric treatment cylinders, the calculated value of the outlet humidity value of the multiple target fabric treatment cylinders is the average value of the outlet humidity values ​​of the multiple target fabric treatment cylinders.

[0045] This embodiment can periodically detect the air humidity value of each air outlet when multiple fabric processing cylinders are in standby mode, in order to avoid excessive ambient humidity causing dampness inside the cylinders.

[0046] In one optional implementation, the target fabric processing cylinder that meets the cylinder drying conditions is determined based on the outlet humidity value of each air outlet. This includes: determining the target fabric processing cylinder that meets the cylinder drying conditions by comparing the outlet humidity value of each target fabric processing cylinder with a preset humidity threshold. The cylinder drying conditions are that the outlet humidity value is greater than the preset humidity threshold, and the preset humidity threshold is dynamically adjusted according to the ambient humidity. For example, the higher the ambient humidity, the lower the preset humidity threshold, which effectively prevents the damp environment inside the cylinder from worsening. Conversely, the lower the ambient humidity, the higher the preset humidity threshold. In this case, the external environment will not exacerbate the humidity situation inside the cylinder, which can reduce the number of times the cylinder drying process runs in a dry environment and save energy.

[0047] In one alternative implementation, refer to Figure 2 The flowchart describes how drying parameters are determined based on the outlet humidity value of the target fabric treatment cylinder and the number of target fabric treatment cylinders, including: S21. Determine the number of target fabric treatment tubes and the proportion of target fabric treatment tubes for each humidity level; S22. Determine the drying time correction factor based on the proportion of each humidity level and the number of treatment tubes for the target fabric. S23. The drying time is dynamically adjusted based on the drying time correction coefficient and the basic drying time. The higher the humidity level, the larger the drying time correction coefficient; the more target fabric treatment cylinders there are, the larger the drying time correction coefficient; the drying parameters also include the outlet air temperature and / or outlet air velocity, which increase with the increase of the humidity level of the target fabric treatment cylinders, but do not exceed the equipment safety threshold.

[0048] By adjusting the drying parameters in the above manner, the drying effect and efficiency of the target fabric treatment cylinder can be further improved.

[0049] In a preferred embodiment, the preset detection conditions further include: at least one fabric treatment drum completing the washing program within a preset time period. This allows for timely drying of the inside of the fabric treatment drum after the washing program is completed, reducing bacterial growth within the drum. The preset time period is, for example, 5 to 30 minutes.

[0050] It should be noted that the washing program defined in this embodiment only performs the washing, rinsing and dehydration process of the fabric, without drying, so as to distinguish it from the washing and drying program that requires both washing and drying.

[0051] Reference Figure 3 The flowchart and control method also include the following steps: S31. Determine the microbial content in the drain of the first target fabric treatment drum during the washing program. The first target fabric treatment drum is the target fabric treatment drum that has undergone the washing program within a preset time period. S32. Determine the second target fabric treatment tube that meets the sterilization conditions based on the microbial content; S33. Before, after and / or during the drying process of the second target fabric treatment cylinder, the sterilization module is activated to sterilize the second target fabric treatment cylinder.

[0052] In this embodiment, when each fabric treatment drum is running a washing program, a microbial detection device detects the microbial content in the wastewater to determine whether the internal environment of the fabric treatment drum needs to be sterilized.

[0053] After identifying the target fabric treatment drum requiring drum drying, it is also necessary to determine if a first target fabric treatment drum has undergone a washing program within a preset time period. If so, the microbial content in the wastewater of the first target fabric treatment drum is further measured. If the microbial content exceeds a preset level, this fabric treatment drum is designated as the second target fabric treatment drum. Since the microbial content in the wastewater of the second target fabric treatment drum exceeds the standard, sterilization treatment is required. Because the hot airflow during drum drying cannot achieve thorough and effective sterilization, additional sterilization methods are needed to sterilize the inside of the drum. Sterilization treatment can be performed before, after, or during drum drying, or at least two of these three times to ensure sufficient sterilization of the drum environment.

[0054] In one alternative implementation, refer to Figure 4 The flowchart and control method also include the following steps: S41. Before starting the sterilization process, the washing information of the second target fabric treatment drum during the most recent washing program is also determined. S42. Control the sterilization strategy for the second target fabric treatment drum based on the washing information.

[0055] In this embodiment, after determining the second target fabric treatment drum that requires sterilization, before sterilizing the second target fabric treatment drum, the washing information of the last washing program performed on the second target fabric treatment drum is first determined. The washing information includes the washing mode and / or fabric material. This is because different washing information reflects different conditions inside the drum.

[0056] For example, for highly absorbent fabrics such as cotton and linen, there is less residual water and relatively less microbial residue after the washing cycle; while for less absorbent fabrics such as down, there is more residual water and relatively more microbial residue in the drum after the washing cycle. For washing modes with longer wash times, cleaning is more thorough, resulting in relatively less microbial residue in the drum; while for washing modes with shorter wash times, cleaning is less thorough, resulting in relatively more microbial residue in the drum. For washing modes with higher spin speeds, there is less residual water and relatively less microbial residue in the drum after the washing cycle; for washing modes with lower spin speeds, there is more residual water and relatively more microbial residue in the drum after the washing cycle. For washing modes with higher water temperatures, there is relatively less microbial residue in the drum after the washing cycle; for washing modes with lower water temperatures, there is relatively more microbial residue in the drum after the washing cycle.

[0057] Therefore, by adopting different sterilization strategies based on the washing information of the last executed washing program before sterilization treatment, better sterilization effect can be achieved while reducing sterilization energy consumption.

[0058] For example, the sterilization module includes a steam sterilization device and an ultraviolet sterilization device. The steam sterilization device is located in the fabric treatment drum and is used to introduce high-temperature steam into the fabric treatment drum to sterilize the internal environment of the drum. The ultraviolet sterilization device is located in the air inlet duct and / or air outlet duct to sterilize the airflow passing through the fabric treatment drum. A sterilization strategy for the second target fabric treatment drum is controlled based on washing information, including: The lower the washing water temperature, the longer the UV sterilization time and the stronger the steam sterilization intensity. Lower water temperatures result in more microorganisms remaining in the drum, hence the need for longer UV sterilization time and stronger steam sterilization.

[0059] The lower the spin speed of the washing mode, the longer the UV sterilization time and the stronger the steam sterilization intensity. The lower the spin speed, the more water remains in the drum, and the more microorganisms remain in the water. Therefore, a longer UV sterilization time and a stronger steam sterilization intensity are used.

[0060] The shorter the washing cycle, the longer the UV sterilization time and the stronger the steam sterilization intensity. Shorter washing cycles result in less thorough cleaning and more residual microorganisms in the water; therefore, a longer UV sterilization time and stronger steam sterilization intensity are used.

[0061] The less absorbent the fabric, the longer the UV sterilization time and the stronger the steam sterilization intensity. Less absorbent fabric retains more moisture inside the chamber, which in turn harbors more microorganisms; therefore, a longer UV sterilization time and a stronger steam sterilization intensity are required.

[0062] It should be noted that the steam sterilization intensity can be adjusted by controlling the steam temperature and / or steam duration. For example, the higher the steam temperature and the longer the steam duration, the stronger the steam sterilization intensity.

[0063] In one optional implementation, the control method further includes: adjusting the drying parameters of the second target fabric treatment drum according to the washing conditions of the last washing program executed by the second target fabric treatment drum; the drying parameters include drying time and hot air volume; wherein: The lower the spin speed of the washing mode, the more water remains in the drum, so a longer drying time is used, and / or a larger hot air volume is used in terms of hot air distribution.

[0064] The less absorbent the fabric, the more moisture remains inside the drum, so a longer drum drying time should be used, and / or a larger hot air volume should be used in terms of hot air distribution.

[0065] It should be noted that when there is only one target fabric treatment cylinder and the target fabric treatment cylinder needs to increase the hot air volume, the hot air volume can be increased directly by increasing the speed of the blower.

[0066] If there are multiple target fabric processing cylinders, and only some of them require increased hot air volume, then the hot air outlet volume is distributed by the air volume distribution structure set in the air duct, so that more airflow flows to the target fabric processing cylinders that require increased hot air volume.

[0067] In other feasible methods, the humidity detection device and the microbial detection device can be linked for control. A data fusion algorithm can be introduced into the system to comprehensively analyze the data from the humidity detection device and the microbial detection device. The drying + sterilization program will only be activated when both high humidity and high microbial content are detected simultaneously, thus avoiding unnecessary energy consumption.

[0068] The technical solution of this embodiment will be described in detail below with reference to a specific example.

[0069] Combination Figure 5The flowchart illustrates a control method for a multi-drum washer-dryer integrated equipment. The specific implementation steps are as follows: S01: When the spin-drying stage of the washing program of any fabric treatment drum is completed and all fabric treatment drums are in standby mode, the humidity detection process is started. When the washing machine completes the spin-drying program, the control system automatically enters the detection process to determine whether each fabric treatment drum needs to be dried. S02: Detect the humidity of the air outlet of each fabric processing cylinder to determine whether to start the cylinder drying program. A humidity sensor is installed at the air outlet of each fabric processing cylinder. During the humidity detection process, the air supply fan is started, the humidity sensor detects the humidity at the air outlet, and compares it with the preset humidity, for example, 60%. If the humidity of the air outlet of the fabric processing cylinder exceeds the preset humidity, it is determined that there is residual moisture inside the fabric processing cylinder, and the cylinder drying program needs to be started; if multiple fabric processing cylinders detect high humidity at the same time, the system determines that multiple fabric processing cylinders need to be dried synchronously; otherwise, there is no need to proceed to the next step. S03: Start the drum drying program and dynamically adjust the drying time. For fabric processing drums with high humidity detected, the system automatically starts the drum drying program, and the heating module in the drying duct is activated. The heating module is, for example, an electric heater. The drying time is T = humidity value × A × K, where K is a coefficient and A is a constant greater than 0. For example, A is 15 minutes. The value of K is related to the number of fabric processing drums that need to be dried. When only one fabric processing drum needs to be dried, the coefficient is 1; when multiple fabric processing drums need to be dried, K is 1.5. Furthermore, when multiple fabric processing drums need to be dried, the humidity value is the average humidity value of the multiple fabric processing drums that need to be dried. S04: Obtain the microbial content in the drain detected during the washing program. A nanoscale biosensor is set at the drain outlet. The system detects the microbial content in the drain in real time during the draining process of the washing program. If the detected microbial content exceeds the preset content, the sterilization mode is triggered. Otherwise, the drying continues until the drying is finished. S05: When the microbial content exceeds the preset level, the sterilization mode is triggered. A miniature condensate collector at the bottom of the fabric treatment drum collects the condensate generated during drying and / or drum drying. The miniature heating tube inside the condensate collector and the ultraviolet sterilization device in the air duct are activated simultaneously. The miniature heating tube heats the condensate to generate steam, and a temperature sensor monitors the water temperature in real time. When the water temperature exceeds 90℃, the heating tube is turned off after 30 seconds, and the residual heat inside the drum and the drying device continue to carry out sterilization and drying. S06: After completing the drum drying and sterilization processes, the system automatically enters standby mode, automatically shuts down all actuators, and switches the washer-dryer combo to standby mode.

[0070] This embodiment also provides an electronic device, which includes one or more processors and a non-transitory computer-readable storage medium storing program instructions.
