Description

Technical Field

[0001] This invention belongs to the field of washing machines, and particularly relates to a clothing processing device and its drying control method and apparatus. Background Technology

[0002] With advancements in home appliance technology and improvements in people's living standards, users are increasingly demanding higher standards for washing machine functionality, performance, and energy consumption. Washer-dryer combos have been popular since their introduction, but simply wearing clothes straight from the dryer is no longer sufficient for today's more discerning users. Users are now more concerned about drying time, drying effect, and energy consumption.

[0003] Most washer-dryer combos on the market now use water-cooled condensation for drying. However, the condition of the clothes inside the drum changes constantly with factors such as temperature and time. Therefore, some preset drying parameters cannot meet the constantly changing condition of the clothes inside the drum, so they cannot effectively improve drying efficiency and will cause some unnecessary water and electricity consumption.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a garment processing equipment and its drying control method and device, which can dynamically adjust the opening degree or on / off ratio of the condensate valve according to different drying stages, thereby improving drying efficiency and saving energy.

[0006] To solve the above-mentioned technical problems, the first aspect of the present invention provides a drying control method for a garment processing device.

[0007] The garment processing equipment is equipped with a condensing air duct that uses condensate as the cooling medium and a condensate valve that controls the supply of condensate. The condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages.

[0008] Alternatively, the condensate valve can be controlled to increase the water supply during the operating phase when the drying efficiency is relatively high.

[0009] Optionally, the condensate valve has four operating modes: fully open, fully closed, partially open, and intermittent. The condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages, including:

[0010] When the drying stage is in a relatively low-efficiency working phase, control the condensate valve to be fully closed.

[0011] When the drying stage is in a relatively efficient working phase, control the condensate valve to open fully, partially, or intermittently.

[0012] Optionally, the drying stage includes a heating stage, a constant temperature heating stage, a heating and dehumidification stage, and a cooling and wrinkle removal stage. The stages with relatively high drying efficiency include the constant temperature heating stage, the heating and dehumidification stage, and the cooling and wrinkle removal stage, while the stages with relatively low drying efficiency include the heating stage.

[0013] Further, optionally, the drying control method also includes:

[0014] Monitor the temperature inside the drum and determine the current drying stage based on the temperature inside the drum.

[0015] Further, optionally, the temperature inside the drum is monitored, and the current drying stage is determined based on the temperature inside the drum, including:

[0016] During the heating phase, it is determined whether the temperature inside the cylinder is greater than or equal to the first preset temperature; if so, the constant temperature heating phase begins.

[0017] During the constant temperature heating stage, it is determined whether the temperature inside the cylinder is greater than or equal to the third preset temperature; if so, the heating and dehumidification stage is entered.

[0018] During the heating and dehumidification stage, determine whether the temperature inside the drum meets the dryness criteria; if so, proceed to the cooling and wrinkle removal stage.

[0019] During the cooling and wrinkle removal stage, it is determined whether the temperature inside the drum is less than or equal to the fourth preset temperature. If so, the drying process ends.

[0020] The fourth preset temperature is lower than the first preset temperature, and the first preset temperature is lower than the third preset temperature.

[0021] Alternatively, the opening degree or on / off ratio of the condensate valve at different drying stages is positively correlated with the weight of the drying load.

[0022] Alternatively, the garment processing equipment is equipped with an electric air heating device, a drying fan, and a washing tub drive motor. The condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages, and is adjusted in coordination with the electric air heating device, the drying fan, and the washing tub drive motor.

[0023] Optionally, the condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages, and is adjusted in conjunction with the air electric heating equipment, drying fan, and washing tub drive motor to achieve the optimal drying effect for that stage, including:

[0024] During the heating phase, the air electric heating equipment and drying fan are controlled to work, the washing tub drive motor is controlled to run at a first preset speed and a first preset speed-stop ratio, and the condensate valve is controlled to close.

[0025] At the end of the heating phase, the air electric heating equipment and drying fan should be stopped.

[0026] Optionally, the condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages, and is adjusted in coordination with the air electric heating equipment, the drying fan, and the washing tub drive motor, including:

[0027] During the constant temperature heating stage, it is determined whether the temperature inside the cylinder has dropped to the second preset temperature;

[0028] If so, control the air electric heating equipment and drying fan to start working, and control the condensate valve to enter water at the first preset opening degree or the first preset start-stop ratio;

[0029] At the end of the constant temperature heating stage, the control air electric heating equipment, drying fan, and condensate valve stop working.

[0030] Optionally, the condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages, and is adjusted in coordination with the air electric heating equipment, the drying fan, and the washing tub drive motor, including:

[0031] During the heating and dehumidification stage, determine whether the temperature inside the cylinder has dropped to the second preset temperature;

[0032] If so, control the air electric heating equipment and the drying fan to start working, and control the condensate valve to enter water in the fully open mode;

[0033] At the end of the heating and dehumidification phase, the air electric heater stops working.

[0034] Optionally, the condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages, and is adjusted in coordination with the air electric heating equipment, the drying fan, and the washing tub drive motor, including:

[0035] During the cooling and wrinkle removal stage, the condensate valve is controlled to enter water in a fully open mode, and the washing tub drive motor is controlled to run at a second preset speed and a second preset speed-stop ratio.

[0036] When drying is finished, control the drying fan, condensate valve, and washing tub drive motor to stop running;

[0037] The second preset speed is less than the first preset speed, and the second preset speed-to-stop ratio is less than the first preset speed-to-stop ratio.

[0038] A second aspect of the present invention also provides a drying control device for a garment processing apparatus, comprising one or more processors and a non-transitory computer-readable storage medium storing program instructions, wherein when the one or more processors execute the program instructions, the one or more processors are configured to implement any of the methods provided in the first aspect.

[0039] A third aspect of the present invention also provides a garment processing apparatus that employs any of the methods provided in the first aspect, or includes the control device provided in the second aspect.

[0040] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0041] Based on the existing drying system structure, this invention maintains the drying process at a high efficiency level for an extended period through the coordinated operation of air electric heating, a fan, a condensate valve, and the rotation of the inner drum and a motor. Unlike previous methods with fixed on / off parameters, this invention allows for the efficient use of condensate water during the high-efficiency drying phase, reducing water consumption during lower or saturated drying phases, thereby lowering water consumption. Furthermore, the control of the air electric heating, fan, condensate valve, and motor effectively improves drying efficiency. For a water-cooled washer-dryer, this invention achieves higher dehumidification efficiency within the same time and energy consumption.

[0054] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0055] In the description of this invention, it should be noted that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0056] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0057] Most washer-dryer combos on the market currently use water-cooled condensation for drying. However, the condition of the clothes inside the drum changes constantly due to factors such as temperature and time. Preset drying parameters cannot meet the constantly changing conditions of the clothes inside the drum, thus failing to effectively improve drying efficiency and causing unnecessary water and electricity consumption. Therefore, this embodiment provides a drying control method for a garment processing device. The garment processing device is equipped with a condensation duct using condensate as the cooling medium and a condensate valve to control the supply of condensate.

[0058] The drying control method of this embodiment will be described below with reference to the accompanying drawings.

[0059] Combination Figure 1 A schematic diagram of the process, the drying control method includes S2:

[0060] S2, the condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages.

[0061] In this embodiment, the condensate valve is dynamically adjusted in opening degree or on / off ratio according to different drying stages, thereby controlling the amount of condensate entering the system. This ensures that only an appropriate amount of condensate is introduced for heat exchange, maintaining the temperature inside the cylinder and evaporation efficiency, thus reducing water consumption and improving drying efficiency. The condensate valve includes both an adjustable valve body and a non-adjustable valve body. When adjusting the on / off ratio to control the condensate flow, a non-adjustable valve body is preferred; when adjusting the opening degree to control the condensate flow, an adjustable valve body is preferred.

[0062] Alternatively, the drying control method may further include the following steps:

[0063] The condensate valve is controlled to increase the water supply during the relatively high drying efficiency stage.

[0064] Regarding evaporation efficiency: The drying fan and electric air heating equipment operate continuously, maintaining a relatively high temperature inside the drum, resulting in high efficiency. Regarding condensation efficiency: Sufficient condensate water comes into contact with the humid, hot air for heat exchange; ensuring an appropriate amount of condensate water is introduced for heat exchange, and minimizing excess condensate water as it lowers the drum temperature and reduces evaporation efficiency; during the drying process, the moisture in the clothes continuously decreases, naturally reducing the amount of moisture evaporated, thus requiring less condensate water. Therefore, controlling the amount of condensate water is crucial to maintaining the drum temperature and evaporation efficiency.

[0065] During the drying process, the clothes are fully heated and evaporate, making it difficult for the temperature inside the drum to rise. When evaporation reaches saturation, the heat will increase the temperature inside the drum, which can easily rise to its upper limit, maximizing evaporation efficiency. At this point, increasing the water supply to the condensate valve, such as keeping it normally open, allows the drum to maintain a saturated state with the highest evaporation efficiency for an extended period. This also allows more condensate to come into contact with the humid air for condensation and heat exchange, removing most of the moisture from the load. This is also when the condensation efficiency is highest, thus achieving the optimal drying effect at this stage.

[0066] Alternatively, the condensate valve may have four operating modes: fully open, fully closed, partially open, and intermittent. The partially open mode refers to controlling the condensate valve to open to any degree between its adjustable maximum and minimum opening to control the amount of condensate. The intermittent operating mode refers to controlling the condensate valve to control the amount of condensate by controlling the opening and closing ratio of the condensate valve.

[0067] Further, optionally, combined Figure 2 The flowchart shows that step S2 includes S21 to S22, where:

[0068] S21, when the drying stage is in a working stage with relatively low drying efficiency, control the condensate valve to open in the fully closed mode.

[0069] S22, when the drying stage is in a relatively high drying efficiency working stage, control the condensate valve to open fully, half-open, or intermittently.

[0070] Specifically, during the high-efficiency drying stage, the amount of condensate can be increased by adjusting the opening degree or on / off ratio of the condensate valve according to the actual situation inside the drum, or by continuously feeding water in a fully open mode. This ensures that most of the water is consumed during the high-efficiency drying stage, while reducing water consumption during the low-efficiency or saturated drying stages, thereby achieving the goal of reducing water consumption and improving drying efficiency.

[0071] Optionally, the drying stage includes a heating stage, a constant temperature heating stage, a heating and dehumidification stage, and a cooling and wrinkle removal stage. The stages with relatively high drying efficiency include the constant temperature heating stage, the heating and dehumidification stage, and the cooling and wrinkle removal stage, while the stages with relatively low drying efficiency include the heating stage.

[0072] Specifically, the heating stage is the initial stage of the drying process, entered after weighing. Drying efficiency is low during this stage, and condensation does not occur. After the heating stage, the constant-temperature heating stage begins. This stage is longer and the temperature rises more slowly, allowing the clothes to be fully heated and evaporating heat. Therefore, the temperature inside the drum does not rise easily, but the introduction of condensate water ensures condensation and heat exchange. After the constant-temperature heating stage, the drying efficiency reaches saturation, and the heating and dehumidification stage begins. Evaporation efficiency is highest during this stage. Increasing the condensate water flow at this point maintains the drum at its highest saturation level for an extended period, while also keeping the condensation efficiency high for a longer time. After the load is deemed dry, the cooling and wrinkle-removing stage begins. During this stage, the condensate water flow is controlled by adjusting the opening degree or on / off ratio of the condensate water valve, causing the temperature inside the drum to drop rapidly.

[0073] Further, optionally, combined Figure 3 The process diagram shows that the drying control method also includes S1:

[0074] S1, monitor the temperature inside the drum, and determine the current drying stage based on the temperature inside the drum.

[0075] As the drying process progresses, the temperature inside the drum changes, which can be represented by T. In this embodiment, the temperature sensors used for the drum temperature are those found in conventional garment processing equipment (such as washer-dryer combos), including those for the air inlet, air outlet, and water temperature. The current drum temperature is determined by combining the temperature sensor readings with the drying program parameters to identify the current drying stage.

[0076] Further, optionally, combined Figure 4a The flowchart shows that S1 includes S11 to S14, where:

[0077] S11, during the heating stage, determine whether the temperature inside the cylinder is greater than or equal to the first preset temperature (T1); if so, enter the constant temperature heating stage;

[0078] The heating stage is the initial stage of the drying process, which begins after weighing is completed. During the heating stage, the heating stage ends when the temperature inside the drum reaches the first preset temperature, and the process transitions to the constant temperature heating stage.

[0079] S12, during the constant temperature heating stage, determine whether the temperature inside the cylinder is greater than or equal to the third preset temperature (T3); if so, proceed to the heating and dehumidification stage.

[0080] S13, during the heating and dehumidification stage, determine whether the temperature inside the cylinder meets the dryness condition T. 判干 If so, proceed to the cooling and wrinkle removal stage;

[0081] S14, during the cooling and wrinkle removal stage, determine whether the temperature inside the drum is less than or equal to the fourth preset temperature (T4). If so, the drying process ends.

[0082] Among them, the fourth preset temperature T4 is less than the first preset temperature T1, and the first preset temperature T1 is less than the third preset temperature T3.

[0083] Further, optionally, combined Figure 4b The flowchart shows the process of monitoring the inlet temperature T during the heating phase. 进风 And the temperature T inside the cylinder, determine T 进风 Does it satisfy ≥T? off (T off The start of the heating phase is determined by whether the temperature inside the cylinder meets or exceeds the preset value (T1). During the constant-temperature heating phase, the temperature T at the air inlet is also monitored. 进风 Determine T based on the temperature inside the cylinder. 进风 Does it satisfy ≥T? off (T offThe start of the constant temperature heating stage is determined by whether the temperature inside the drum meets the preset value (or whether it is ≥T1). During the heating and dehumidification stage, as the moisture content of the drying load decreases, the change in temperature inside the drum, ΔT, gradually increases. The start time is determined by whether ΔT meets the preset value (or whether it is ≥T1). 判干 To determine when this phase is about to end.

[0084] Further optionally, the drying control method further includes:

[0085] The opening degree or on / off ratio of the condensate valve at different drying stages is positively correlated with the weight of the drying load.

[0086] Common garment drying equipment typically introduces water at a fixed flow rate after reaching the target temperature for the first time, continuing until drying is complete. During the drying process, the moisture content of the garments continuously decreases, resulting in less water evaporation and thus less condensate required. Therefore, it's crucial to control the amount of condensate to maintain the drum temperature and evaporation efficiency. This embodiment uses weighing to determine the drying load weight and, based on this weight, determines the on / off ratio of the condensate valve at different drying stages. This ensures that only an appropriate amount of condensate is introduced for heat exchange at each stage, minimizing excess condensate that lowers the drum temperature and reduces evaporation efficiency, thereby improving drying efficiency, achieving better drying results, and saving water.

[0087] Specifically, the drying load weight is determined by its range. Taking three ranges as an example, these represent heavy, moderate, and light drying loads, respectively. For the same drying stage, different drying loads require more condensate, resulting in a larger on / off ratio or opening degree for the condensate valve. Conversely, lighter loads require less condensate, leading to a smaller on / off ratio or opening degree for the condensate valve. In particular, when the drying load weight is light, a fixed on / off ratio or opening degree can be used to control the condensate valve's water inlet.

[0088] Alternatively, the garment processing equipment is equipped with an electric air heating device, a drying fan, and a washing drum drive motor, combined with... Figure 5 The flowchart in S2 also includes:

[0089] The condensate valve is controlled to dynamically adjust its opening degree or on / off ratio according to different drying stages. In the process, it works in conjunction with the air electric heating equipment, the drying fan, and the washing tub drive motor to achieve the optimal drying effect for that stage.

[0090] The drying process of the garment processing equipment in this embodiment is divided into four stages based on the temperature inside the drum: the heating stage, the constant temperature heating stage, the heating and dehumidification stage, and the cooling and wrinkle removal stage. In each stage, the operating states of the air heater, fan, condensate valve, and motor are different to achieve the optimal drying effect for that stage.

[0091] Further, optionally, combined Figure 6a The process diagram shows that in S2, the condensate valve is dynamically adjusted in opening degree or on / off ratio according to different drying stages. This adjustment works in conjunction with the air heating equipment, drying fan, and washing tub drive motor to achieve the optimal drying effect for that stage, including S21 to S22.

[0092] S21, during the heating stage, control the air electric heating equipment and the drying fan to work, control the washing tub drive motor to run at the first preset speed and the first preset speed-stop ratio, and control the condensate valve to close.

[0093] S22, at the end of the heating phase, control the air electric heating equipment and the drying fan to stop working.

[0094] Specifically, the heating stage is the initial stage of the drying process, which begins after weighing. During this stage, the air heater and fan operate, and the motor continuously rotates in both directions at a first preset speed V1 and a first preset speed-to-stop ratio X1. The condensate valve is closed. In this stage, to ensure a rapid rise in the drum temperature, the motor operates to allow the load to be heated evenly and to evaporate a small amount of moisture. When the drum temperature reaches the first preset temperature (or the upper limit temperature of the air inlet), the air heater and drying fan stop operating, and the heating stage ends.

[0095] Further, optionally, combined Figure 6b The process diagram shows that in S2, the condensate valve is dynamically adjusted in opening degree or on / off ratio according to different drying stages. This adjustment works in conjunction with the air heating equipment, drying fan, and washing tub drive motor to achieve the optimal drying effect for that stage. S23 to S25, where:

[0096] S23, during the constant temperature heating stage, determine whether the temperature inside the cylinder has dropped to the second preset temperature (T2); if so, execute S24;

[0097] S24, control the air electric heating equipment and drying fan to start working, and control the condensate valve to enter water at the first preset opening degree or the first preset start-stop ratio;

[0098] S25, at the end of the constant temperature heating stage, controls the air electric heating equipment, drying fan and condensate valve to stop working.

[0099] Specifically, in the constant temperature heating stage: After the heating stage ends, when the temperature inside the drum rapidly drops to T2 (or the lower limit temperature of the air inlet), the air electric heater, fan, and condensate valve begin to operate. The condensate valve starts accepting water at a first preset on / off ratio or a first preset opening degree. The on / off ratio and flow rate of the condensate valve are determined based on the washer-dryer's specifications. For example, the inlet flow rate for a 12kg machine can be higher than that for a 10kg machine; the on / off ratio settings for 1600W and 800W air electric heaters are different. During this stage, due to the entry of condensate, the temperature inside the drum rises slowly, and the evaporation efficiency gradually increases. Simultaneously, the fixed on / off ratio of condensate ensures condensation heat exchange during this stage, removing some of the moisture from the load. When the temperature inside the drum reaches the third preset temperature (or the upper limit temperature of the air inlet), the evaporation efficiency reaches saturation, the air electric heater and drying fan stop operating, and the constant temperature heating stage ends.

[0100] Further, optionally, combined Figure 6c The process diagram shows that in S2, the condensate valve is dynamically adjusted in opening degree or on / off ratio according to different drying stages. This adjustment, in conjunction with the air heating equipment, drying fan, and washing tub drive motor, aims to achieve the optimal drying effect for that stage, including S26 to S28.

[0101] S26, During the heating and dehumidification stage, determine whether the temperature inside the cylinder has dropped to the second preset temperature; if so, proceed to S27.

[0102] S27 controls the air electric heating equipment and drying fan to start working, and controls the condensate water valve to enter water in the fully open mode;

[0103] S28 controls the air electric heating to stop working at the end of the heating and dehumidification stage.

[0104] The second preset temperature T2 is less than the first preset temperature T1 and greater than the fourth preset temperature T4. Specifically, during the heating and dehumidification stage: after the constant temperature heating stage ends, when the temperature inside the cylinder rapidly drops to the second preset temperature (or the lower limit temperature of the air inlet), the air electric heater, fan, and condensate valve start working. The condensate valve continuously supplies water at a flow rate of Z. When the temperature inside the cylinder reaches the third preset temperature (or the upper limit temperature of the air inlet), the evaporation efficiency of the load is at its highest. The condensate valve being constantly open at a flow rate of Z allows the cylinder to maintain a saturated state with the highest evaporation efficiency for a long time. Furthermore, the constant opening allows more condensate to contact the humid air for condensation and heat exchange, removing most of the moisture from the load. This is also when the condensation efficiency is highest. Due to the reduction in load moisture, the temperature inside the cylinder more easily reaches the third preset temperature (or the upper limit temperature of the air inlet). The constantly open condensate valve extends the heating time and shortens the cooling time, keeping the condensation efficiency at a high level for a longer period. When the temperature inside the cylinder reaches the dryness condition satisfying ΔT ≥ T... 判干When the load is determined to be dry, the heating and dehumidification phase ends, and the air electric heater stops working. The condensate inlet flow rate Z is determined by the condensate valve, which is fixed; therefore, the flow rate is the optimal value derived from experiments and machine specifications.

[0105] Further, optionally, combined Figure 6d The process diagram shows that in S2, the condensate valve is dynamically adjusted in opening degree or on / off ratio according to different drying stages. This adjustment, in conjunction with the air electric heating equipment, drying fan, and washing tub drive motor, aims to achieve the optimal drying effect for that stage. This includes S29 to S30, where:

[0106] S29, during the cooling and wrinkle removal stage, control the condensate water valve to enter water in a fully open mode, and control the washing tub drive motor to run at a second preset speed and a second preset speed-stop ratio;

[0107] S30 controls the drying fan, condensate valve, and washing tub drive motor to stop operating when drying is complete. Drying is complete when the temperature inside the tub is less than or equal to the fourth preset temperature.

[0108] The second preset speed is lower than the first preset speed, and the second preset speed-to-stop ratio is lower than the first preset speed-to-stop ratio. Specifically, the cooling and wrinkle-removing stage begins after the load is judged to be dry. The air electric heater stops working, while the fan and condensate valve continue to operate in their previous states. The motor continues to rotate forward and backward at the second preset speed and the second preset speed-to-stop ratio. The condensate valve continues to supply water at a flow rate of Z. The continuous water supply from the condensate valve allows the temperature inside the drum to drop rapidly. The lower speed of the fan and the lower speed-to-stop ratio of the motor effectively remove wrinkles caused by prolonged high-temperature drying, allowing the load to reach a soft state suitable for immediate wear after drying. When the temperature inside the drum is less than or equal to the fourth preset temperature, the load inside the drum has been sufficiently cooled and wrinkle-removed, and drying is complete.

[0109] It should be noted that:

[0110] (1) Temperature inside the cylinder: T4 < T2 < T1 < T3, the temperature range is 45℃ to 65℃. The specific value is related to the structure and the specifications of the drying system components, and is not specifically limited here.

[0111] (2) The condensate inlet flow rate is determined by the condensate valve. For a single model, the condensate valve is fixed. Therefore, the condensate inlet flow rate is the optimal value obtained from experiments and machine specifications.
