Description

Technical Field

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

[0002] With the improvement of people's living standards, washer-dryer combos have gradually become one of the essential home appliances due to their convenience of combining washing and drying functions. In washer-dryer combos, the preheating efficiency of the drying system directly affects the overall drying effect and energy consumption. Currently, washer-dryer combos on the market typically start the drying system for preheating only after the washing cycle is completed. This method results in a long waiting time between the end of washing and the start of drying, affecting the user experience.

[0003] In the existing technology, there are some solutions for preheating control of washer-dryer combos. However, existing washer-dryer combos usually only start drying preheating at a specific stage of the washing program (such as the last rinse or spin-drying stage), failing to make full use of the entire washing program for staged preheating, resulting in insufficient preheating efficiency, especially in low-temperature environments where the preheating time is long, affecting the overall drying efficiency. Summary of the Invention

[0004] To overcome the technical problem that washing and drying integrated equipment in related technologies cannot dynamically adjust the drying and preheating state according to the characteristics of each processing stage in the washing process to achieve a gradual increase in the temperature inside the drum, resulting in low preheating efficiency and high energy consumption, this application provides a drying and preheating method, electronic equipment, and washing and drying integrated equipment.

[0022] When the processing parameters in the rinsing stage meet the first drying preheating conditions, the compressor of the heat pump drying system is controlled to preheat for a third time at a third preset power when the air blower is started, and the cooling fan is controlled to start to dissipate heat from the compressor after the preheating is completed; when the processing parameters in the rinsing stage meet the second drying preheating conditions, the electric heating device is controlled to heat the rinsing water to the first water temperature.

[0023] When the processing parameters in the dehydration stage meet the corresponding drying preheating conditions, the compressor of the heat pump drying system is controlled to preheat at the fourth preset power until the dehydration stage ends, while the blower is turned off.

[0024] Among them: the first duration is less than the second duration, the second duration is less than or equal to the third duration, and the first preset power, the second preset power, and the third preset power are all less than the fourth preset power.

[0044] This embodiment combines processing parameters from each washing stage to control the drying preheating state, ensuring that the drum temperature gradually increases with each stage. This multi-stage heat accumulation allows the drum to build up heat before drying, ensuring rapid heating to the target drying temperature upon startup. This reduces the time required for temperature rise during drying, improves drying efficiency, shortens drying time, and reduces energy consumption. Furthermore, by gradually increasing the drum temperature, this embodiment solves problems such as insufficient preheating efficiency, high energy consumption, and unstable operation in washer-dryer combos during the drying preheating stage.

[0047] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the invention. Attached Figure Description

[0048] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.

[0049] Figure 1 This is a control flow diagram of a washer-dryer combo according to an exemplary embodiment.

[0050] Figure 2 This is a control flow diagram of a washer-dryer combo, illustrated by a specific example.

[0051] Figure 3 This is a structural block diagram of an electronic device according to an exemplary embodiment. Detailed Implementation

[0052] 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.

[0053] First, the structure of the washer-dryer combo device in this embodiment will be briefly introduced.

[0054] 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.

[0055] Multiple fabric processing tubes include an inner tube and an outer tube, with the inner tube rotatably disposed inside the outer tube.

[0056] 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.

[0057] 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 air duct. In a specific example, the outlet air duct includes 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 method of the drying system can be electric heating drying or heat pump drying. Heat pump drying is preferred, as it reduces drying energy consumption and improves drying efficiency.

[0058] 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.

[0059] Furthermore, the washer-dryer combo also includes a heating device located at the bottom of the outer drum for heating the washing water.

[0060] Furthermore, the sterilization module also includes a temperature detection device located at the bottom of the outer drum, which can detect the temperature of the incoming water and / or the washing water.

[0061] The drying and preheating method of the washer-dryer integrated equipment in this embodiment will be described in detail below.

[0062] This embodiment provides a drying preheating method for a washer-dryer combo device, referring to... Figure 1 The flowchart shows that the drying and preheating method includes the following steps:

[0063] S11. In the washing program of the washing and drying mode, multiple processing stages are executed sequentially. During the execution of multiple processing stages, the processing parameters of each processing stage are obtained respectively.

[0064] S12. Determine whether the corresponding drying and preheating conditions are met based on the processing parameters of each processing stage.

[0065] S13. When it is determined that the corresponding drying and preheating conditions are met, the drying and preheating means and / or drying and preheating parameters are controlled according to the processing stage of drying and preheating, so that the temperature inside the cylinder is gradually increased as each processing stage proceeds.

[0066] In this embodiment, when the washer-dryer is running in washer-dryer mode, the processing parameters for each processing stage are acquired before each stage is executed during the washing program. For example, the processing stages include a water inlet stage, a main wash stage, a rinsing stage, and a spin-drying stage. The processing parameters are dynamically determined based on the processing stage. For instance, the processing parameters corresponding to the water inlet stage include the inlet water temperature; the processing parameters corresponding to the main wash stage include the washing mode; the processing parameters corresponding to the rinsing stage include the number of rinses; and the processing parameters corresponding to the spin-drying stage include the spin-drying speed.

[0067] After obtaining the corresponding processing parameters for each processing stage, it is determined whether the corresponding drying preheating conditions are met based on the processing parameters. If the drying preheating conditions are met, the drum environment is dried and preheated in the corresponding processing stage so that the drum temperature increases step by step as each processing stage proceeds. Furthermore, by combining the characteristics of different processing stages and adopting different drying preheating methods and / or drying preheating parameters, a better preheating effect can be obtained with lower preheating energy consumption. After the washing program ends and the drying program begins, the target drying temperature can be quickly reached, effectively shortening the drying time and reducing energy consumption.

[0068] In one example, the drying preheating method includes hot water preheating and hot air preheating. When the drying preheating method is hot water preheating, the drying preheating parameters include at least one of preheating water temperature and preheating power; when the drying preheating method is hot air preheating, the drying preheating parameters include at least one of preheating power, preheating duration, preheating air temperature, preheating air velocity, blower start / stop status, and cooling fan start / stop status. In the case of a heat pump drying system, the cooling fan is used to dissipate heat from the compressor of the heat pump system.

[0069] In one alternative implementation, the drying preheating means and / or drying preheating parameters are controlled according to the processing stage in which drying preheating is performed, including:

[0070] When the processing parameters of multiple processing stages meet the corresponding drying and preheating conditions, drying and preheating treatments are controlled for each of the multiple processing stages. The drying and preheating intensity is related to the processing stage; the later the processing stage is executed, the stronger the drying and preheating intensity. The drying and preheating intensity is adjusted according to the drying and preheating parameters. This embodiment gradually increases the drying and preheating intensity to ensure that the target drying temperature is reached or even close to the target temperature before entering the drying process, while maintaining low preheating energy consumption.

[0071] In one optional implementation, the processing stages include a washing water intake stage, a main wash stage, a rinsing stage, and a spin-drying stage. During the washing water intake stage, the main wash stage, and the spin-drying stage, preheating is performed using hot air preheating. During the rinsing stage, a combined approach of hot air preheating and hot water preheating is used to further ensure a gradual increase in drum temperature without significantly increasing energy consumption. Preferably, the combined approach of hot air preheating and hot water preheating during the rinsing stage includes: performing hot air preheating first, followed by hot water preheating during the rinsing stage.

[0072] In the specific implementation, the drying system is a heat pump drying system, which uses hot air generated by the heat pump drying system to preheat the inside of the drum to further reduce energy consumption.

[0073] In one alternative implementation, an electric heating device is installed at the bottom of the outer drum of the washer-dryer combo to heat the water inside the drum, and the drying system adopts a heat pump drying system.

[0074] Combination Figure 2 The flowchart shows that during the operation of the washer-dryer combo, the washing and drying process is first executed in the washing and water intake stage. When the processing parameters of the washing and water intake stage reach the preset drying and preheating conditions, the compressor of the heat pump drying system is controlled to preheat for a first preset time at the first preset power while the blower is started.

[0075] After the washing and water intake stage ends, the main washing stage begins. If the processing parameters of the main washing stage meet the corresponding drying and preheating conditions, the system will control the compressor of the heat pump drying system to switch to the second preset power to continue preheating for the second duration while the air blower is running.

[0076] After the main wash stage, the rinsing stage begins. If the processing parameters meet the first drying preheating conditions, the blower must be kept running. At this time, the compressor is controlled to preheat at the third preset power for the third duration. Immediately after the preheating stage, the cooling fan is started to effectively dissipate heat from the compressor and prevent overheating. If the processing parameters in the rinsing stage meet the second drying preheating conditions, the electric heating device is started to heat the rinsing water to the preset first water temperature.

[0077] After the rinsing stage ends, the dehydration stage begins. If the processing parameters of this stage meet the corresponding drying preheating conditions, the system will control the compressor of the heat pump drying system to preheat at the fourth preset power until the dehydration stage ends.

[0078] In this configuration, the first preheating time is shorter than the second preheating time, the second preheating time is less than or equal to the third preheating time, and the first, second, and third preset power are all less than the fourth preset power. This ensures that the preheating process is gradually adjusted according to the needs of different stages, achieving efficient and energy-saving operation. Preferably, the first, second, and third preset power are all the same.

[0079] In a preferred embodiment, when the processing parameters for the washing water intake stage, the main wash stage, and the rinsing stage all meet the corresponding drying preheating conditions, the hot air velocity in the washing water intake stage is less than the hot air velocity in the main wash stage and less than or equal to the hot air velocity in the rinsing stage. This is because the presence of low-temperature washing water may accelerate heat loss within the drum during the washing water intake, main wash, and rinsing stages. Therefore, different hot air velocities are used in different processing stages to reduce heat loss. Specifically, in the water intake stage, the preheating power is relatively low, and a higher air velocity is used to accelerate the airflow within the drum to remove the cooling energy generated during the water intake process. In the rinsing stage, the preheating power is relatively high, so a relatively low air velocity is used to maintain the warm environment within the drum, thereby maintaining the drum temperature and reducing energy consumption.

[0080] It should be noted that the hot air velocity, the hot air velocity during the main wash, and the compressor frequency during the hot air preheating process in the rinsing stage are all relatively low, for example, the compressor frequency range is 0~50Hz. Using a low air velocity for a short period of time during the rinsing stage will not cause the compressor to be overloaded.

[0081] Preferably, the drying system includes a compressor and a cooling fan, the cooling fan being used to dissipate heat from the compressor; the drying preheating method further includes: after the first drying preheating process in the rinsing stage is completed, the cooling fan is also started to dissipate heat from the compressor, so as to avoid the compressor accumulating a large load due to continuous start-stop after multiple preheating in different processing stages. At this time, the cooling fan is started to quickly reduce the load on the compressor, ensuring the efficient operation of the compressor in subsequent processing stages and drying procedures.

[0082] In one optional implementation, the processing parameters corresponding to the washing water inlet stage include the inlet water temperature; combined with Figure 2 The flowchart, which determines whether the corresponding drying preheating conditions are met based on the processing parameters of each processing stage, also includes: in the washing water inlet stage, determining whether the inlet water temperature is lower than a first water temperature, for example, 15 ℃. If the inlet water temperature is lower than the first water temperature, it is determined that the corresponding drying preheating conditions are met.

[0083] In this embodiment, when the inlet water temperature is lower than the first water temperature, the washing and water intake stage will result in a lower temperature environment inside the drum. During the drying process, heating up at this ambient temperature will require higher drying power and a longer heating time, significantly increasing preheating energy consumption. Therefore, preheating is necessary to reduce preheating energy consumption. If the inlet water temperature is greater than or equal to the first water temperature, preheating is unnecessary; water can be directly added to the target inlet water level.

[0084] After reaching the target water level, the water intake phase ends and the main wash phase begins.

[0085] In one optional implementation, the processing parameters corresponding to the main wash stage include the washing mode; combined with Figure 2 The flowchart, based on the processing parameters of each processing stage, determines whether the corresponding drying preheating conditions are met. It also includes: in the main wash stage, determining whether the washing mode is a heated washing mode; if the washing mode is a heated washing mode, further determining whether the target washing water temperature is lower than a preset water temperature, for example, 60℃. If the target washing water temperature is lower than the preset water temperature, and the washing water is heated to the target washing water temperature, then the corresponding drying preheating conditions are met; if the washing mode is not a heated washing mode, then the corresponding drying preheating conditions are met.

[0086] In this embodiment, when the washing mode is a heated washing mode and the target washing water temperature is lower than the second water temperature, it indicates that washing is performed at this target washing water temperature, and the drum's internal temperature is also relatively low. To reduce preheating energy consumption in the drying process, preheating is also required during the main wash stage. To avoid excessive system power consumption due to simultaneous water heating and preheating, preheating is performed after the washing water temperature reaches the target washing water temperature. Heating the washing water also provides heat to the drum's internal environment, thereby reducing preheating energy consumption. If the target washing water temperature is greater than or equal to the second water temperature, preheating is unnecessary. The hot water from the heated water will keep the drum warm, eliminating the need for preheating; the preset main wash duration can be run directly at the target washing water temperature. Furthermore, if the washing mode is not a heated washing mode and room temperature water is used, the room temperature water will result in a relatively low drum temperature, requiring direct preheating.

[0087] In a preferred embodiment, combined with Figure 2 The flowchart shows that, in the heated washing mode, the preheating parameters during the washing stage are adjusted according to the target washing water temperature. Specifically, the higher the target washing water temperature, the lower the preheating power, thus further reducing energy consumption while ensuring the temperature inside the drum is increased.

[0088] After the target washing time is reached, the main wash phase ends and the rinsing phase begins.

[0089] In one optional implementation, the processing parameters corresponding to the rinsing stage include the number of rinsing cycles. Figure 2 The flowchart determines whether the corresponding drying and preheating conditions are met based on the processing parameters of each stage, including:

[0090] During the rinsing stage, determine whether the current rinsing number is the last rinsing; if the current rinsing number is not the last rinsing, determine that the first drying preheating condition is met; if the current rinsing number is the last rinsing, determine that the second drying preheating condition is met.

[0091] In this embodiment, hot air preheating is used before the final rinse to maintain a warm environment inside the drum, and hot water preheating is used during the final rinse to reduce heat loss during the injection of rinse water. In a preferred embodiment, the hot air preheating parameters and hot water preheating parameters during the rinsing process are determined according to the fabric material. For example, for heat-resistant fabrics, such as cotton fabrics, a higher preheating water temperature and a lower hot air temperature are used; for heat-sensitive fabrics, a lower preheating water temperature and a higher preheating air temperature are used. During the rinsing stage, the hot water preheating and hot air preheating work together to increase the drum temperature with lower preheating energy consumption.

[0092] It should be noted that if the rinsing is only done once, the rinsing water will be preheated directly during that rinsing.

[0093] After the preset main wash duration is reached, the main wash phase ends and the rinsing phase begins.

[0094] In one optional implementation, the processing parameters corresponding to the dehydration stage include the dehydration rotation speed; combined with Figure 2 The flowchart describes how the processing parameters for each stage determine whether the corresponding drying preheating conditions are met. This includes: in the dehydration stage, determining whether the dehydration speed reaches the preset dehydration speed; and if the dehydration speed reaches the preset dehydration speed, determining that the corresponding drying preheating conditions are met. The preset dehydration speed is, for example, 900 rad. When the dehydration speed reaches the target dehydration speed, the high-speed rotation of the inner cylinder allows airflow to circulate within the cylinder and the air ducts of the drying system, thereby reducing the need for the blower and lowering energy consumption.

[0095] This embodiment also provides an electronic device, which includes one or more processors and a non-transitory computer-readable storage medium storing program instructions. When the one or more processors execute the program instructions, the one or more processors are used to implement the drying and preheating method of the washer-dryer integrated device provided in the foregoing embodiments of this application.

[0096] Specifically, such as Figure 3 As shown, the electronic device includes a processor 100, at least one communication bus 200, a user interface 300, at least one external communication interface 400, and a memory 500. The communication bus 200 is configured to enable communication between these components. The user interface 300 may include a display screen, and the external communication interface 400 may include standard wired and wireless interfaces. The memory 500 stores a drying preheating method for a washer-dryer combo. The processor 100 is used to employ the aforementioned method when executing the drying preheating method for the washer-dryer combo stored in the memory 500.

[0097] The electronic device in this embodiment can be a controller for a washer-dryer combo, including a central processing unit (CPU), a memory, and an input / output interface. The memory stores program instructions for implementing the drying and preheating method, and the CPU executes these program instructions to control the various components of the washer-dryer combo to operate according to the drying and preheating method described above.

[0098] Specifically, the electronic device performs the following functions by executing program instructions: in the washing program of the washing and drying mode, multiple processing stages are executed sequentially, and the processing parameters of each processing stage are acquired during the execution of the multiple processing stages; the processing parameters are dynamically determined according to the processing stage.

[0099] Determine whether the corresponding drying and preheating conditions are met based on the processing parameters of each processing stage; if the corresponding drying and preheating conditions are met, control the drying and preheating methods and / or drying and preheating parameters according to the processing stage in which drying and preheating are performed, so that the temperature inside the cylinder increases step by step as each processing stage proceeds.

[0100] The program instructions in the electronic device also include functional modules that control the drying system to deliver hot air into the drum at different preheating intensities during the washing water intake stage, main wash stage, rinsing stage and dehydration stage. The specific control process is the same as described above.

[0101] The electronic device also includes a sensor interface for connecting water temperature sensors, air temperature sensors, etc., to obtain various parameter data during the washing program. Additionally, the electronic device has a control interface for sending control signals to actuators such as the compressor and cooling fan.

[0102] By using this electronic device to perform the drying preheating method described above, the heating efficiency of the washer-dryer combo in the drying process can be effectively improved, the time it takes for the temperature inside the drum to reach the target drying temperature can be shortened, the overall drying time can be reduced, and thus the drying effect can be improved.

[0103] This embodiment also provides a washer-dryer combo device, which operates according to the drying and preheating method for washer-dryer combo devices provided above, or includes the electronic equipment provided above.

[0104] The washer-dryer combo equipment of this embodiment includes a drying system, which includes, for example, a compressor, a cooling fan, and a blower. This washer-dryer combo equipment, when the processing parameters at each stage meet the corresponding drying preheating conditions, can control the drying preheating methods and / or drying preheating parameters according to the processing stage in which drying preheating is performed. This allows the drum temperature to gradually increase with each processing stage, shortening the time it takes for the drum temperature to reach the set temperature, thereby reducing the overall drying time and improving the drying effect.
