Description

[0002] Clothing processing equipment, such as dryers or washing machines with drying functions, can heat wet clothes after washing to remove moisture and dry the clothes.

[0003] In related technologies, garment processing equipment such as washer-dryer combos typically incorporate a heat pump drying system, including an evaporator, compressor, and condenser. This system uses an internal airflow loop between the heat pump drying system and the garments to recover heat, allowing the hot air exhausted from the heat pump drying system to dry the clothes. However, because heat pump drying systems primarily rely on internal refrigerant, excessively high refrigerant temperatures can easily lead to adverse effects during the drying process. In particular, when a washer-dryer combo executes its fast-drying program, it usually requires continuous operation of auxiliary heating structures to increase heat source intensity, resulting in a more significant rise in refrigerant temperature and consequently reducing drying efficiency.

Obviously, those skilled in the art can obtain other drawings based on these drawings without creative effort.

[0057] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0058] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0059] The technical solution provided in this disclosure is applicable to a clothing processing device having a accommodating cavity and a drying assembly. The drying assembly has an air duct communicating with the accommodating cavity. The drying assembly includes a condenser, an evaporator, a first auxiliary cooling structure, and a second auxiliary cooling structure. Along the circulation path of the circulating air, the first auxiliary cooling structure is located upstream of the condenser, and the second auxiliary cooling structure is located upstream of the evaporator. Additionally, the drying assembly includes an auxiliary heating structure and a compressor to assist in heating the circulating air entering the accommodating cavity using the auxiliary heating structure. For example, the first auxiliary cooling structure may include an air-cooled heat exchanger, which operates based on a communicating damper and an exhaust port. For instance, by controlling the damper to open, lower-temperature external air can be introduced into the air duct of the circulating air to pre-cool the circulating air passing through the condenser. For example, the second auxiliary cooling structure may include a water-cooled heat exchanger, which operates based on water circulation. For instance, the water circulation can exchange heat with the circulating air to use lower-temperature circulating water to cool the higher-temperature circulating air, thereby pre-cooling the circulating air passing through the evaporator. For example, the garment processing equipment may be a heat pump dryer, a heat pump washer-dryer combo, or other heat pump drying equipment, and is not limited thereto.

[0060] The control method for the clothing processing equipment provided in this embodiment can reduce the temperature of the circulating air passing through the evaporator and condenser by controlling the operation of the first auxiliary cooling structure and the second auxiliary cooling structure during the drying process. This reduces the temperature of the refrigerant flowing in the evaporator and condenser, thereby keeping the refrigerant at the corresponding location within a suitable temperature range. This reduces the adverse effects caused by excessively high refrigerant temperature and helps improve the drying effect.

[0061] In some embodiments, before controlling the operation of the first auxiliary cooling structure, a first detection temperature can be obtained. When it is determined that the first detection temperature meets a first cooling condition, such as when the first detection temperature is greater than a preset temperature threshold, the first auxiliary cooling structure is controlled to operate, such as controlling the operation of an air-cooled heat exchanger to draw in cooler external air through a damper to pre-cool the circulating air passing through the condenser. Exemplarily, the first detection temperature may include the inlet temperature of the circulating air and / or the refrigerant outlet temperature of the compressor.

[0062] In some embodiments, before controlling the operation of the second auxiliary cooling structure, the outlet temperature of the circulating air can be obtained first. When it is determined that the outlet temperature meets the second cooling condition, such as when the outlet temperature is greater than or equal to the input refrigerant temperature of the second auxiliary cooling structure, the second auxiliary cooling structure is controlled to operate, such as controlling the water-cooled heat exchanger to introduce cooling water to pre-cool the circulating air passing through the evaporator. When it is determined that the outlet temperature is less than the input refrigerant temperature of the second auxiliary cooling structure, the second auxiliary cooling structure is controlled to stop operating.

[0063] In some embodiments, after controlling the operation of the second auxiliary cooling structure, the second auxiliary cooling structure can be controlled to alternately open and close according to a preset time rhythm, and the operating parameters of the second auxiliary cooling structure can be obtained, including the operating time and / or the number of opening and closing times; when it is determined that the operating time reaches a time threshold and / or the number of opening and closing times reaches a number threshold, the second auxiliary cooling structure is controlled to stop operating, thus enriching the way to determine when the second auxiliary cooling structure stops operating.

[0064] In some embodiments, when the drying program is running, the compressor and the auxiliary heating structure are controlled to operate simultaneously, and the compressor operates at a first frequency to increase the drying temperature as quickly as possible in a short period of time.

[0065] In some embodiments, by obtaining the refrigerant outlet temperature of the compressor and determining that the refrigerant outlet temperature is equal to or greater than a first temperature threshold, the operating frequency of the compressor is controlled to be adjusted to a second frequency lower than the first frequency, so as to reduce the refrigerant outlet temperature of the compressor and reduce the adverse effects caused by excessively high refrigerant outlet temperature.

[0066] In some embodiments, when the refrigerant outlet temperature is determined to be equal to or greater than a second temperature threshold, the compressor's operating frequency is adjusted to a third frequency lower than the second frequency to reduce the compressor's refrigerant outlet temperature. When the refrigerant outlet temperature is determined to be equal to or less than the third temperature threshold, indicating that the refrigerant is in a more suitable temperature range, the compressor's operating frequency is restored to the second frequency. The second temperature threshold is greater than the first temperature threshold, and the third temperature threshold is less than the second temperature threshold but greater than the first temperature threshold. Thus, by adaptively adjusting the compressor's operating frequency, the compressor's refrigerant outlet temperature can be kept within a more suitable temperature range, ensuring a higher temperature during clothes drying, thereby achieving rapid clothes drying.

[0067] The control method, apparatus, medium, and equipment of the garment processing equipment provided in this disclosure will be described by way of example below with reference to the accompanying drawings.

[0068] Figure 1This is a schematic flowchart illustrating a control method for a garment processing device according to an embodiment of the present disclosure. The garment processing device to which this control method is applicable includes at least a accommodating cavity for accommodating garments and a drying assembly with an air duct. The air duct is connected to the accommodating cavity, and the drying assembly includes a condenser, an evaporator, a first auxiliary cooling structure disposed upstream of the condenser along the circulation path of the circulating air, and a second auxiliary cooling structure disposed upstream of the evaporator along the circulation path of the circulating air. The upstream of the condenser and the upstream of the evaporator are both located along the circulation path of the circulating air, meaning that in the circulation path of the circulating air in the air duct, the circulating air first passes through the second auxiliary cooling structure, then through the evaporator, and then successively through the first auxiliary cooling structure and the condenser. Furthermore, this control method can be executed by a control device, such as the controller of the garment processing device, which can be implemented in software and / or hardware.

[0069] Reference Figure 1 The control method may include the following steps:

[0070] S110, based on the drying program operation, controls the operation of the first auxiliary cooling structure and the second auxiliary cooling structure.

[0071] The second auxiliary cooling structure is used to pre-cool the circulating air passing through the evaporator, and the first auxiliary cooling structure is used to pre-cool the circulating air passing through the condenser. For example, refer to... Figure 2 Starting from the accommodating cavity 21, the circulating air passes through the accommodating cavity 21, the second auxiliary cooling structure 229, the evaporator 222, the first auxiliary cooling structure 224, the condenser 225, the auxiliary heating structure 226 in the direction of the circulating air circulation path, and then passes through the accommodating cavity 21 again to circulate.

[0072] Specifically, when the drying process is running, the second auxiliary cooling structure first cools the circulating air leaving the containment chamber to lower its temperature in advance, so that the resulting lower-temperature circulating air passes through the evaporator. When the refrigerant flowing in the evaporator exchanges heat with the circulating air, its temperature will not rise too much. Then, the first auxiliary cooling structure cools the circulating air again, so that the cooled circulating air passes through the condenser. At this time, when the refrigerant flowing in the condenser exchanges heat with the circulating air, its temperature will not rise too much. Compared with not setting the first and second auxiliary cooling structures, this method is equivalent to reducing the temperature of the refrigerant flowing in the evaporator and condenser.

[0073] The first auxiliary cooling structure can be positioned close to the condenser, and the second auxiliary cooling structure can be positioned close to the evaporator. For example, the second auxiliary cooling structure can be positioned at the front end of the evaporator, and the first auxiliary cooling structure can be positioned at the front end of the condenser. This ensures that the circulating air cooled by the second auxiliary cooling structure can pass through the evaporator promptly, and the circulating air cooled by the first auxiliary cooling structure can pass through the condenser promptly. This prevents the temperature of the circulating air flowing through the evaporator and condenser from becoming too high, and consequently, prevents the temperature of the refrigerant exchanging heat with the circulating air from becoming too high. Therefore, the pre-cooling effect of the second and first auxiliary cooling structures on the circulating air can be sufficiently used to control the refrigerant temperature from becoming too high. The distance between the second auxiliary cooling structure and the evaporator, and the distance between the first auxiliary cooling structure and the condenser, can be set according to actual cooling requirements and are not limited here.

[0074] It's easy to understand that the refrigerant is located in the refrigerant circulation loop within the garment processing equipment. Structures used to circulate the refrigerant, such as the evaporator, compressor, and condenser, exchange heat with the circulating air during the drying process within this loop. Furthermore, a second auxiliary cooling structure pre-cools the circulating air passing through the evaporator, ensuring that the air subsequently passing through the evaporator is not too hot. Consequently, the refrigerant circulating in the evaporator does not overheat when exchanging heat with this circulating air. Similarly, the first auxiliary cooling structure then cools the circulating air leaving the evaporator, ensuring that the circulating air subsequently passing through the condenser is at a lower temperature. Consequently, the refrigerant circulating in the condenser does not overheat when exchanging heat with this circulating air. This lowers the temperature of the refrigerant circulating in the refrigerant circulation loop, ensuring that the refrigerant remains within a suitable temperature range.

[0075] In contrast to existing technologies that reduce heat source intensity due to excessively high refrigerant temperature, thus extending drying time, the control method for the clothing processing equipment provided in this disclosure reduces these adverse effects and facilitates rapid clothing drying.

[0076] The control method for the garment processing equipment provided in this disclosure includes: controlling the operation of a first auxiliary cooling structure and a second auxiliary cooling structure based on the operation of a drying program. Thus, during the drying process, by controlling the operation of the first and second auxiliary cooling structures, the temperature of the circulating air passing through the evaporator and condenser can be reduced, thereby reducing the temperature of the refrigerant flowing in the evaporator and condenser. This ensures that the refrigerant at the corresponding location is within a suitable temperature range, reducing the adverse effects caused by excessively high refrigerant temperature and improving the drying effect.

[0077] In some embodiments, Figure 1 Based on this, before controlling the operation of the first auxiliary cooling structure in S110, the following steps are also included:

[0078] Obtain the first detection temperature.

[0079] The first detected temperature includes the inlet temperature of the circulating air and / or the refrigerant outlet temperature of the compressor. The inlet temperature of the circulating air represents the temperature of the circulating air just before it passes through the receiving cavity. For example, a temperature sensor or a temperature and humidity sensor can be installed at the inlet of the receiving cavity to collect the inlet temperature of the circulating air and transmit it to the control device so that the control device can obtain the inlet temperature. The refrigerant outlet temperature of the compressor represents the temperature of the refrigerant when it flows out of the compressor. For example, a temperature sensor or a temperature and humidity sensor can be installed at the outlet of the compressor to collect the refrigerant outlet temperature of the compressor and transmit it to the control device so that the control device can obtain the refrigerant outlet temperature.

[0080] In other embodiments, other methods may be used to monitor the inlet temperature of the circulating air and the refrigerant compression temperature of the compressor, which are not limited here.

[0081] It is understandable that, since the temperature of the circulating air at different locations in the garment processing equipment is correlated, and the temperature of the refrigerant is correlated with the temperature of the circulating air, in other embodiments, the temperature of the circulating air at other locations or the temperature of the refrigerant can also be used to characterize the current operating status of the garment processing equipment, which is not limited here.

[0082] It should be noted that the first detected temperature is one of the parameters used to determine whether to control the operation of the first auxiliary cooling structure. Specifically, based on the operation of the drying program, by acquiring the inlet temperature of the circulating air and / or the refrigerant outlet temperature of the compressor, it is possible to further determine whether the first cooling condition is met, so that the operation of the first auxiliary cooling structure can be controlled when the first cooling condition is determined to be met.

[0083] To address this, S110 controls the operation of the first auxiliary cooling structure, specifically including the following steps:

[0084] Based on the first detected temperature meeting the first cooling condition, the operation of the first auxiliary cooling structure is controlled.

[0085] The first cooling condition is a criterion used to determine whether the operation of the first auxiliary cooling structure needs to be controlled. Specifically, if the first detected temperature meets the first cooling condition, the operation of the first auxiliary cooling structure is controlled, that is, the first auxiliary cooling structure is controlled to pre-cool the circulating air passing through the condenser; conversely, if the first detected temperature does not meet the first cooling condition, the operation of the first auxiliary cooling structure is not controlled.

[0086] In some embodiments, the first cooling condition in the above steps includes:

[0087] The first detected temperature is greater than the preset temperature threshold.

[0088] The preset temperature thresholds for the inlet temperature of the circulating air and the refrigerant outlet temperature of the compressor are different. It should be noted that the preset temperature threshold for the inlet temperature of the circulating air is usually lower than the preset temperature threshold for the refrigerant outlet temperature of the compressor. For example, the preset temperature threshold for the inlet temperature of the circulating air can be 60°C, and the preset temperature threshold for the refrigerant outlet temperature of the compressor can be 70°C. In other embodiments, the above preset temperature thresholds can be set to other values ​​according to actual cooling requirements, which are not limited here.

[0089] For example, when the temperature of the circulating air entering the tank is greater than a preset temperature threshold such as 60°C, it is determined that the first detected temperature meets the first cooling condition, thereby controlling the operation of the first auxiliary cooling structure; conversely, when the temperature of the circulating air entering the tank is less than 60°C, it is determined that the first detected temperature does not meet the first cooling condition, thereby not controlling the operation of the first auxiliary cooling structure.

[0090] Alternatively, when the refrigerant outlet temperature of the compressor is greater than a preset temperature threshold such as 70°C, the first detection temperature is determined to meet the first cooling condition, thereby controlling the operation of the first auxiliary cooling structure; conversely, when the refrigerant outlet temperature of the compressor is less than 70°C, the first detection temperature is determined not to meet the first cooling condition, thereby not controlling the operation of the first auxiliary cooling structure.

[0091] In this embodiment of the present disclosure, when the first detected temperature is greater than the preset temperature threshold, it indicates that the temperature of the circulating air entering the drum and / or the refrigerant discharge temperature of the compressor is high. At this time, by controlling the operation of the first auxiliary cooling structure, the temperature of the circulating air passing through the evaporator can be reduced, thereby reducing the temperature of the refrigerant, avoiding the adverse effects caused by excessively high refrigerant temperature, and ensuring high drying efficiency.

[0092] In some embodiments, the first auxiliary cooling structure includes an air-cooled heat exchanger, which includes a connected damper and an exhaust port, and the exhaust volume of the exhaust port can be equal to the intake volume of the damper; external air can enter through the damper and exit through the exhaust port; during this process, the external air entering the circulating air path can also pass through the containment cavity before being discharged. Exemplarily, the exhaust port can be located at the front end of the water box assembly and connected to the air outlet duct through an air passage formed inside the water box assembly. The air outlet duct is connected to the containment cavity, thereby enabling the air after passing through the containment cavity to pass through the air outlet duct and the air passage inside the water box assembly before being discharged through the exhaust port.

[0093] Based on this, Figure 1 Based on this, the operation of the first auxiliary cooling structure is controlled in S110, specifically including the following steps:

[0094] Control the operation of the air-cooled heat exchanger to draw in outside air through the damper.

[0095] In this process, the temperature of the outside air is lower than that of the circulating air; this cooler outside air can also be referred to as cold outside air. The operation of the air-cooled heat exchanger is controlled to keep the damper open, drawing in cooler outside air. This cooler outside air is used to pre-cool the circulating air that is about to pass through the condenser, thereby reducing the temperature of the refrigerant that exchanges heat with the circulating air.

[0096] Specifically, when the first detected temperature meets the first cooling condition, the air-cooled heat exchanger is controlled to draw in cooler air from the outside environment through the damper. This outside air can pre-cool the circulating air passing through the condenser, so that the resulting cooler circulating air enters the condenser. This circulating air is then used to cool the refrigerant flowing in the condenser. This can also be understood as the refrigerant heating rate being relatively slow in the technical solution provided in this embodiment. At the same time, based on the refrigerant circulating in the refrigerant circulation loop, the temperature rise of the refrigerant flowing in the evaporator and compressor is also reduced. When the circulating air flows to the evaporator along the circulation path, because the circulating air temperature is low, the refrigerant will not heat up too much when exchanging heat with the circulating air in the refrigerant circulation loop, thereby delaying the rise of the refrigerant temperature in the refrigerant circulation loop and reducing the rate of refrigerant temperature rise.

[0097] In this way, the cooler outside air drawn in by the damper cools the refrigerant flowing through the condenser, slowing down the temperature rise of the refrigerant in the refrigerant circulation loop and keeping the temperature of the circulating air entering the drum rising. This helps to achieve rapid drying of clothes while keeping the refrigerant within a suitable temperature range.

[0098] In some embodiments, before controlling the operation of the second auxiliary cooling structure in S110, the following steps are also included:

[0099] Obtain the outlet temperature of the circulating air.

[0100] The outlet temperature is one of the parameters used to determine whether to control the operation of the second auxiliary cooling structure. It represents the temperature of the circulating air as it exits the container after passing through the clothes contained within. For example, a temperature sensor or a temperature and humidity sensor can be installed at the outlet of the container to collect the outlet temperature of the circulating air and transmit it to the control device. In other embodiments, other methods can be used to monitor the outlet temperature of the circulating air, which are not limited here.

[0101] Specifically, based on the operation of the drying program, by obtaining the outlet temperature of the circulating air, it is possible to further determine whether it meets the second cooling condition, so as to control the operation of the second auxiliary cooling structure when it is determined that the outlet temperature meets the second cooling condition.

[0102] To address this, S110 controls the operation of the second auxiliary cooling structure, specifically including the following steps:

[0103] The second auxiliary cooling structure is controlled to operate based on the fact that the outlet temperature meets the second cooling condition.

[0104] The second cooling condition is used to determine whether the operation of the second auxiliary cooling structure needs to be controlled. Specifically, if the outlet temperature meets the second cooling condition, the second auxiliary cooling structure is controlled to operate, and the circulating air leaving the containment chamber is cooled by the second auxiliary cooling structure to form a lower temperature circulating air; conversely, if the outlet temperature does not meet the second cooling condition, the operation of the second auxiliary cooling structure is not controlled.

[0105] In some embodiments, the second cooling condition in the above steps includes:

[0106] The outlet temperature is greater than or equal to the input refrigerant temperature of the second auxiliary cooling structure.

[0107] It should be noted that the second auxiliary cooling structure and the heat pump drying system are independently operating structures, and the type of refrigerant circulating in the heat pump drying system may be different from that in the second auxiliary cooling structure. For example, the refrigerant circulating in the heat pump drying system may be Freon, while the refrigerant in the second auxiliary cooling structure may be water; this is not limited or elaborated upon here.

[0108] The input refrigerant temperature of the second auxiliary cooling structure is the temperature of the refrigerant input to the second auxiliary cooling structure, which is the temperature of the refrigerant before it has exchanged heat with the circulating air, i.e., the temperature of the refrigerant before it exchanges heat with the circulating air.

[0109] In this embodiment, when the outlet temperature of the circulating air is greater than or equal to the input refrigerant temperature of the second auxiliary cooling structure, it indicates that the temperature of the circulating air about to pass through the second auxiliary cooling structure is not lower than the temperature of the input refrigerant. Through heat exchange between the circulating air and the refrigerant, the temperature of the circulating air can be reduced. For example, the outlet temperature of the circulating air can be 90°C, and the input refrigerant temperature of the second auxiliary cooling structure can be 10°C. In this case, the outlet temperature is determined to meet the second cooling condition, thereby controlling the operation of the second auxiliary cooling structure. Conversely, when the outlet temperature of the circulating air is lower than the input refrigerant temperature of the second auxiliary cooling structure, it indicates that the temperature of the circulating air about to pass through the second auxiliary cooling structure is lower than the temperature of the input refrigerant. Through heat exchange between the circulating air and the refrigerant, the temperature of the circulating air cannot be reduced. For example, the outlet temperature of the circulating air can be 70°C, and the input refrigerant temperature of the second auxiliary cooling structure can be 75°C. In this case, the outlet temperature is determined not to meet the second cooling condition, and therefore the operation of the second auxiliary cooling structure will not be controlled to avoid further increases in the circulating air temperature, thus avoiding adverse effects caused by excessively high temperatures and affecting drying efficiency.

[0110] In some embodiments, the second auxiliary cooling structure includes a water-cooled heat exchanger, and the refrigerant is cooling water; Figure 1 Based on this, the operation of the second auxiliary cooling structure is controlled in S110, specifically including the following steps:

[0111] Control the cooling water supply to the water-cooled heat exchanger.

[0112] The cooling water is usually tap water used by the garment processing equipment to perform the washing operation. In addition, it should be noted that, based on the working principle of the water-cooled heat exchanger, when the water-cooled heat exchanger is running, it will continuously receive and discharge cooling water, so as to achieve parallel intake and discharge of cooling water and realize the cooling water circulation.

[0113] For example, when the clothing processing equipment performs a washing operation, the temperature of the tap water can be acquired and recorded. Then, when the clothing processing equipment performs a drying operation, the outlet temperature can be compared with the previously recorded tap water temperature to obtain a comparison result. For example, when the outlet temperature of the circulating air is greater than or equal to the temperature of the tap water, it indicates that the outlet temperature meets the second cooling condition, thereby controlling the inlet and outlet of tap water in the water-cooled heat exchanger to cool the circulating air leaving the containment chamber.

[0114] It is understood that a temperature sensor for sensing water temperature, such as a negative temperature coefficient (NTC) thermistor or other sensor with temperature sensing function, can be provided at the bottom of the receiving cavity to monitor the temperature of tap water. In other embodiments, the temperature sensor may be placed in other locations that are convenient for sensing the temperature of tap water, and this is not limited to these locations.

[0115] In this way, by cooling the circulating air leaving the containment cavity through a water-cooled heat exchanger before entering the evaporator, the circulating air passing through the evaporator will not be too hot. Consequently, when the refrigerant flowing in the evaporator exchanges heat with the circulating air, its temperature will not rise too much. This slows down the temperature rise of the refrigerant in the refrigerant circulation loop and allows the temperature of the circulating air entering the containment cavity to continue to rise, which is beneficial for both the refrigerant and the circulating air entering the containment cavity to be within a suitable temperature range.

[0116] As can be seen from the above embodiments, by using the second auxiliary cooling structure and the first auxiliary cooling structure to cool the circulating air in sequence, the overall temperature of the refrigerant in the refrigerant circulation loop is lower when the circulating air exchanges heat with the refrigerant in the refrigerant circulation loop. This enhances the cooling effect on the refrigerant in the refrigerant circulation loop and better delays the rise in the temperature of the refrigerant in the refrigerant circulation loop.

[0117] In some embodiments, Figure 1 Based on this, after controlling the operation of the second auxiliary cooling structure in S110, the following steps are also included:

[0118] The second auxiliary cooling structure is stopped because the outlet temperature is lower than the input refrigerant temperature of the second auxiliary cooling structure.

[0119] Specifically, in conjunction with the above embodiments, when the outlet temperature of the circulating air is lower than the temperature of the tap water, it indicates that the outlet temperature does not meet the second cooling condition. In this case, the second auxiliary cooling structure is controlled to stop operating, such as controlling the second auxiliary cooling structure to stop the intake and discharge of tap water, which is equivalent to shutting down the second auxiliary cooling structure.

[0120] It is understandable that when the outlet temperature is lower than the input refrigerant temperature of the second auxiliary cooling structure, the outlet temperature of the circulating air is not very high. Therefore, the circulating air passing through the evaporator will not be too hot, and there is no need to control the operation of the second auxiliary cooling structure. In this way, water resources are saved and water waste is avoided.

[0121] In some embodiments, Figure 1 Based on this, after controlling the operation of the second auxiliary cooling structure in S110, it also includes:

[0122] Step 1: Control the second auxiliary cooling structure to alternately turn on and off according to a preset time rhythm, and obtain the operating parameters of the second auxiliary cooling structure.

[0123] The preset time interval includes the duration of the second auxiliary cooling structure being on and the duration of the second auxiliary cooling structure being off. For example, taking the second auxiliary cooling structure alternating on and off once as an example, the duration of the second auxiliary cooling structure being on can be 1 minute, and the duration of being off can be 2 minutes; or, the duration of the second auxiliary cooling structure being on can be 3 minutes, and the duration of being off can be 2 minutes. In other embodiments, the duration of the second auxiliary cooling structure being on and off can also be other values. The time interval for alternating on and off of the second auxiliary cooling structure can be set according to the operational requirements of the second auxiliary cooling structure, and is not limited here.

[0124] Furthermore, the timing of each alternating on and off of the second auxiliary cooling structure can be the same or different. For example, taking the second auxiliary cooling structure alternating on and off twice, in scenarios with different timing, when the second auxiliary cooling structure alternating on and off for the first time, its on duration can be 1 minute and its off duration can be 2 minutes; when the second auxiliary cooling structure alternating on and off for the second time, its on duration can be 4 minutes and its off duration can be 1 minute; in scenarios with the same timing, the duration of both on-times of the second auxiliary cooling structure can be 3 minutes each, and the duration of both off-times can be 1 minute each, without limitation.

[0125] The operating parameters include operating time and / or the number of on / off cycles. It is understood that operating time is the total duration for which the second auxiliary cooling structure alternately turns on and off according to a preset time rhythm; the number of on / off cycles refers to the number of times the second auxiliary cooling structure turns on and off during the alternating on / off process.

[0126] For example, only the operating time of the second auxiliary cooling structure may be obtained, or only the number of times the second auxiliary cooling structure is opened and closed may be obtained, or both the operating time and the number of times the second auxiliary cooling structure is opened and closed may be obtained together; there is no limitation here.

[0127] In this way, by obtaining the operating parameters of the second auxiliary cooling structure, it is easier to determine whether the operating parameters meet the relevant conditions of subsequent steps, so as to control whether the second auxiliary cooling structure stops operating based on the judgment result.

[0128] Step 2: Based on the running time reaching the time threshold and / or the number of opening and closing times reaching the number of times threshold, control the second auxiliary cooling structure to stop operating.

[0129] For example, if the operating time of the second auxiliary cooling structure reaches a time threshold, or the number of times the second auxiliary cooling structure is opened and closed reaches a number threshold, or the operating time of the second auxiliary cooling structure reaches a time threshold and the number of times the second auxiliary cooling structure is opened and closed reaches a number threshold, the second auxiliary cooling structure can be controlled to stop operating. No restrictions are placed on the relevant conditions that the second auxiliary cooling structure should meet when it stops operating.

[0130] The number of times threshold can be a threshold for the total number of times the second auxiliary cooling structure is turned on and off, or it can be a threshold for the number of times the second auxiliary cooling structure is turned on and a threshold for the number of times the second auxiliary cooling structure is turned off.

[0131] For example, taking a time threshold of 5 minutes and a number of times threshold, such as a threshold of 8 times for the total number of times the second auxiliary cooling structure is turned on and off, if the running time of the second auxiliary cooling structure reaches 5 minutes and the total number of times the second auxiliary cooling structure is turned on and off reaches 8, then the second auxiliary cooling structure is controlled to stop running; or, the second auxiliary cooling structure can be controlled to stop running when the running time of the second auxiliary cooling structure reaches 5 minutes; or, the second auxiliary cooling structure can be controlled to stop running when the total number of times the second auxiliary cooling structure is turned on and off reaches 8. Here, the specific values ​​of the time threshold and the number of times threshold are not limited.

[0132] Additionally, when the threshold number is the threshold for the number of times the second auxiliary cooling structure is turned on, and the threshold number for the number of times the second auxiliary cooling structure is turned off, please refer to the corresponding examples above for understanding, which will not be elaborated upon or limited here.

[0133] In some embodiments, Figure 2 This is a schematic diagram of the structure of a garment processing device provided in an embodiment of this disclosure, with reference to... Figure 2 The garment processing equipment includes a receiving cavity 21 and a drying assembly 22 with an air duct 221, and the drying assembly 22 includes an evaporator 222, a compressor 223, a first auxiliary cooling structure 224, a condenser 225, an auxiliary heating structure 226, and a second auxiliary cooling structure 229; exemplarily, Figure 2 The refrigerant circulation loop for the evaporator 222, compressor 223 and condenser 225 is shown by the direction of the thick dashed arrow, and the circulation path of the circulating air is shown by the direction of the thin dashed arrow; wherein, the auxiliary heating structure 226 can be set between the condenser 225 and the accommodating cavity 21 to heat up the circulating air that is to pass through the accommodating cavity 21, thereby increasing the temperature of the circulating air and thus improving the drying efficiency.

[0134] It should be noted that the garment processing equipment may also include a housing. Based on this, the spatial relative positions of the compressor 223, evaporator 222, and condenser 225 are illustrated as follows: the compressor 223 may be located at the bottom of the housing, and both the evaporator 222 and the condenser 225 may be located at the top of the housing, with the evaporator 222 and the condenser 225 respectively connected to the compressor 223.

[0135] In addition, a base is usually provided on the top of the housing of the garment processing equipment. The damper is located on the base and is connected to the air duct 221 where the condenser 225 is located. In this way, after the damper cools the circulating air by drawing in the outside air, the cooled circulating air passes through the relevant structures according to the circulating air path. For example, the circulating air passes through the condenser 225 and the auxiliary heating structure 226 in sequence before entering the accommodating cavity 21.

[0136] For example, Figure 3 This is a schematic diagram of the drying process of a garment processing device provided in this embodiment of the present disclosure, specifically a schematic diagram of temperature changing over time. The horizontal axis X1 represents the drying program's running time in minutes, and the vertical axis Y1 represents the temperature in degrees Celsius (°C). L31 represents the curve showing the temperature of the refrigerant flowing from the compressor (i.e., the refrigerant discharge temperature) changing over time; L32 represents the curve showing the temperature of the circulating air entering the containment chamber (i.e., the circulating air inlet temperature) changing over time; L33 represents the curve showing the temperature of the circulating air leaving the containment chamber (i.e., the circulating air outlet temperature) changing over time; L34 represents the curve showing the difference between the inlet and outlet temperatures changing over time; R1, R2, R3, and R4 represent the first, second, third, and fourth intervals, respectively.

[0137] It is understandable that relevant sensors, such as negative temperature coefficient (NTC) thermistors, can be installed between the compressor and condenser, between the auxiliary heating structure and the container, and between the evaporator and the container to sense the refrigerant outlet temperature, the inlet temperature of the circulating air, and the outlet temperature of the circulating air, respectively.

[0138] Specifically, in the first, second, third, and fourth intervals, the refrigerant discharge temperature, inlet temperature, outlet temperature, and the difference between the inlet and outlet temperatures each exhibit corresponding trends. Corresponding measures can be taken to address these trends, ensuring that the inlet temperatures of both the refrigerant and the circulating air are within a suitable range, thereby improving the drying effect. The drying process of the garment processing equipment and the related measures will be explained below through various embodiments.

[0139] In some embodiments, Figure 1 and Figure 3Based on this, the control method also includes the following steps:

[0140] Based on the drying program operation, the compressor and auxiliary heating structure are controlled to operate simultaneously, and the compressor operates at the first frequency.

[0141] Both the compressor and the auxiliary heating structure are heat sources. The auxiliary heating structure can be considered as an auxiliary heat source, such as a heater. Specifically, after the drying program is started, in the initial stage of the drying program, i.e., the first interval, the heat source intensity is increased by controlling the simultaneous operation of the compressor and the auxiliary heating structure, and by controlling the compressor to operate at a first frequency, thereby enabling the drying temperature to be increased as quickly as possible in a short period of time.

[0142] It should be noted that the first frequency is a high frequency. For example, the first frequency may be 75Hz, 80Hz, 90Hz or other higher frequencies, which can be set according to the clothes drying needs of the embodiments of this disclosure, and are not limited thereto.

[0143] In some embodiments, Figure 1 and Figure 3 Based on this, the control method also includes the following steps:

[0144] Step 1: Obtain the refrigerant discharge temperature of the compressor.

[0145] Specifically, during the drying process, the refrigerant outlet temperature of the compressor can be obtained, and it can be further determined whether it meets the corresponding constant-speed drying conditions. When it is determined that the refrigerant outlet temperature meets the corresponding constant-speed drying conditions, the compressor can be controlled to adjust its operating frequency to reduce the refrigerant outlet temperature of the compressor.

[0146] Step 2: Based on the refrigerant outlet temperature being equal to or greater than the first temperature threshold, adjust the compressor's operating frequency to the second frequency.

[0147] The second frequency is lower than the first frequency. Specifically, the constant-speed drying condition can be that the refrigerant outlet temperature is equal to or greater than the first temperature threshold. For example, in the first interval, the refrigerant flowing in the evaporator and condenser is cooled by the second auxiliary cooling structure and the first auxiliary cooling structure, respectively. Although this can reduce the rate of increase of the refrigerant outlet temperature, the refrigerant outlet temperature will still gradually rise. Therefore, if it is determined that the refrigerant outlet temperature is equal to or greater than the first temperature threshold, that is, when the above constant-speed drying condition is met, the first interval of the drying cycle ends and the second interval begins. In the second interval, the compressor is controlled to operate at a second frequency lower than the first frequency, while the heater remains on to achieve stable constant-speed drying of the clothes.

[0148] For example, the first temperature threshold can be 85°C. Specifically, when the refrigerant outlet temperature is equal to or greater than 85°C, the first interval of the drying cycle ends and the second interval of constant-speed drying begins. The value of the first temperature threshold is not limited here.

[0149] In addition, the second frequency can be 50Hz-70Hz, for example, the second frequency can be 55Hz, 60Hz, 65Hz or other frequencies. In other embodiments, the second frequency can also be other frequencies or frequency ranges known to those skilled in the art, and can be adaptively set relative to the first frequency, which is not limited here.

[0150] In some embodiments, Figure 1 and Figure 3 Based on this, the control method also includes the following steps:

[0151] Based on the refrigerant outlet temperature being equal to or greater than the second temperature threshold, the compressor's operating frequency is adjusted to the third frequency.

[0152] Among them, the second temperature threshold is greater than the first temperature threshold, and the third frequency is less than the second frequency.

[0153] Specifically, the constant-speed drying condition can also be that the refrigerant outlet temperature is equal to or greater than the second temperature threshold. In conjunction with the above embodiment, specifically, within the second interval of constant-speed drying, if the compressor's operating frequency is adjusted to the second frequency, and the refrigerant outlet temperature continues to rise and reaches the second temperature threshold, i.e., the above constant-speed drying condition is met, then in the second interval, the compressor is controlled to operate at a third frequency lower than the second frequency, while the heater remains continuously on.

[0154] For example, the second temperature threshold can be 95°C. Specifically, when the refrigerant outlet temperature is equal to or greater than 95°C, the compressor is controlled to operate at a third frequency. The size of the second temperature threshold is not limited here, as long as the second temperature threshold is greater than the first temperature threshold.

[0155] In addition, the third frequency may differ from the second frequency by a preset frequency, such as 10Hz, 13Hz, 15Hz or other frequencies. Taking a 10Hz difference between the third and second frequencies as an example, if the second frequency is 50Hz, then the third frequency is 10Hz lower than the second frequency, that is, the third frequency is 40Hz. In other embodiments, the third frequency may also be other frequencies or frequency ranges known to those skilled in the art, and may be set relative to the second frequency, which is not limited here.

[0156] Thus, by adjusting the compressor's operating frequency to a third frequency when the refrigerant outlet temperature is equal to or greater than the second temperature threshold, the refrigerant outlet temperature of the compressor can be reduced.

[0157] In some embodiments, Figure 1 and Figure 3 Based on this, the control method also includes the following steps:

[0158] Based on the refrigerant outlet temperature being equal to or less than the third temperature threshold, the compressor's operating frequency is controlled to return to the second frequency.

[0159] The third temperature threshold is less than the second temperature threshold, but greater than the first temperature threshold.

[0160] Specifically, the constant-rate drying condition can also be that the refrigerant outlet temperature is equal to or less than the third temperature threshold. In conjunction with the above embodiment, specifically, within the second interval of constant-rate drying, as the compressor operating frequency decreases, the refrigerant outlet temperature of the compressor also decreases. When the refrigerant outlet temperature decreases to meet the above constant-rate drying condition, i.e., the refrigerant outlet temperature is equal to or less than the third temperature threshold, the compressor operating frequency is controlled to return to the second frequency, while the heater remains continuously on.

[0161] For example, the third temperature threshold can be 90°C. Specifically, when the refrigerant outlet temperature is equal to or less than 90°C, the compressor is controlled to resume operation at the second frequency. The size of the third temperature threshold is not limited here, as long as the third temperature threshold is less than the second temperature threshold.

[0162] It should be noted that in the existing drying cycle, if only the compressor is controlled to run and the heater is turned off, although the refrigerant outlet temperature of the compressor can be maintained within a relatively safe temperature range, that is, the refrigerant outlet temperature is maintained at around 85°C, the inlet temperature of the circulating air can only be maintained at around 60°C, thereby reducing the drying speed and prolonging the drying time of the clothes.

[0163] Conversely, if the compressor and heater are operated simultaneously, the temperature of the circulating air entering the drum can be raised to about 80°C to achieve rapid drying of clothes. However, in the middle and later stages of drying, the refrigerant discharge temperature of the compressor will exceed 100°C, which may cause safety problems for the compressor. Therefore, the heater needs to be turned off to avoid the above safety accidents. In this way, by reducing the heat source intensity, the drying speed is reduced and the drying time of clothes is extended.

[0164] In response to the shortcomings of existing drying processes, combined with Figure 3As can be seen from the above corresponding embodiments, the control method of the clothing processing equipment provided in this disclosure, based on turning on the heater, adaptively adjusts the operating frequency of the compressor to keep the refrigerant outlet temperature of the compressor within a suitable temperature range, that is, the refrigerant outlet temperature does not exceed 100°C, while the inlet temperature of the circulating air can be maintained at around 80°C. This solves the problem of poor drying effect caused by the refrigerant temperature rising too high when the fast drying program is running.

[0165] Compared to the existing method of turning off the heater during the drying cycle, the embodiments of this disclosure control the heater to remain on during the first and second intervals of the drying cycle, thereby ensuring the heat source intensity and maximizing the temperature of the circulating air entering the drum, which in turn facilitates the rapid drying of clothes.

[0166] Furthermore, based on the operation of the first and second auxiliary cooling structures, the operating frequency of the compressor can be adaptively adjusted, which can effectively reduce the temperature of the refrigerant at the corresponding location, keeping the refrigerant within a suitable temperature range to ensure that the heater can continue to operate.

[0167] In some embodiments, refer to Figure 3 The difference between the inlet temperature and the outlet temperature of L34 can be represented by dT. L34 has a maximum point in the second interval, and the difference corresponding to this maximum point can be represented by dT_max. If L34 meets the corresponding drying condition, that is, after decreasing by a preset value (represented by β) relative to dT_max, the corresponding dT is obtained, then the clothes are determined to be dry, and the second interval of the drying cycle ends, and the third interval begins.

[0168] Specifically, in the third zone, the heater is turned off, and the compressor is controlled to run at the second frequency for a preset time before entering the fourth zone. Correspondingly, in the fourth zone, the fan is turned on and the compressor is turned off until the temperature inside the container cavity is lower than the preset temperature, such as 50°C, in order to cool the clothes inside the container cavity. The size of the preset temperature is not limited here.

[0169] Combination Figure 3 The control method for the clothing processing equipment provided in this embodiment controls the compressor and auxiliary heating structure, such as a heater, to operate simultaneously, so that the refrigerant outlet temperature of the compressor does not exceed 100°C and the inlet temperature of the circulating air is maintained at around 80°C.
