Description

Control methods, devices, media, and equipment for garment processing equipment

[0001] This disclosure claims priority to Chinese Patent Application No. 202410515784.5, filed on April 26, 2024, entitled “Control Method, Apparatus, Medium and Device for Clothing Processing Equipment”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of clothing processing technology, and in particular to a control method, apparatus, medium, and equipment for clothing processing equipment. Background Technology

[0003] 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.

[0004] In related technologies, clothing 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 clothes 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, even reducing drying efficiency. Furthermore, relying solely on a heat pump drying system results in relatively low drying efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The technical problem to be solved by this disclosure is that the existing technology, which relies mainly on the internal refrigerant for drying, is prone to adverse effects due to excessively high refrigerant temperature during the drying process, and may even reduce the drying effect. Moreover, the drying efficiency is also low when relying solely on the heat pump drying system to dry clothes.

[0065] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments".

[0067] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0068] The technical solution provided in this disclosure is applicable to a garment 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 an evaporator and an auxiliary cooling structure. The auxiliary cooling structure is located on the circulating air path of the air duct and is positioned upstream of the evaporator to pre-cool the circulating air passing through the evaporator. Additionally, the drying assembly may also include a compressor, a condenser, and an auxiliary heating structure. The garment processing device may also include a fresh air structure. The fresh air structure is located on the circulating air path of the air duct and is positioned upstream of the condenser to pre-cool the circulating air passing through the condenser. The compressor is connected between the evaporator and the condenser. The auxiliary heating structure is located on the circulating air path of the air duct and is positioned upstream of the accommodating cavity to heat the circulating air about to pass through the accommodating cavity, thereby improving drying efficiency. For example, the auxiliary cooling structure may be a water-cooled heat exchanger that operates based on a refrigerant, which may be cooling water; the clothing handling equipment may be a heat pump dryer, a heat pump washer-dryer combo, or other heat pump drying equipment, which is not limited herein.

[0069] The control method for the clothing processing equipment provided in this embodiment can pre-cool the circulating air passing through the evaporator during the drying process by controlling the operation of the auxiliary cooling structure, thereby reducing the temperature of the refrigerant in the evaporator. 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 thus improving drying efficiency and ensuring drying effect.

[0070] In some embodiments, before controlling the operation of the auxiliary cooling structure, the outlet temperature of the circulating air can be obtained first. When it is determined that the outlet temperature meets the preset cooling conditions, such as the outlet temperature being greater than or equal to the input refrigerant temperature of the auxiliary cooling structure, the operation of the auxiliary cooling structure is controlled, such as controlling the cooling water entering the water-cooled heat exchanger to reduce the temperature of the circulating air passing through the evaporator, thereby controlling the heating rate of the refrigerant and keeping the refrigerant temperature within a more suitable temperature range.

[0071] In some embodiments, after the auxiliary cooling structure is controlled to operate, if it is determined that the outlet temperature does not meet the preset cooling conditions, such as when the outlet temperature is lower than the input refrigerant temperature of the auxiliary cooling structure, the auxiliary cooling structure is controlled to stop operating, such as when the water-cooled heat exchanger is controlled to stop receiving cooling water.

[0072] In some embodiments, after controlling the operation of the auxiliary cooling structure, the auxiliary cooling structure can be controlled to alternately open and close according to a preset time rhythm, and the operating parameters of the 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 auxiliary cooling structure is controlled to stop operating, thus enriching the way to determine when the auxiliary cooling structure stops operating.

[0073] 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.

[0074] 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 temperature when the refrigerant flows out of the compressor, i.e., the refrigerant outlet temperature, and reduce the adverse effects caused by excessively high refrigerant outlet temperature.

[0075] 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 refrigerant temperature at the compressor outlet, i.e., the 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 refrigerant outlet temperature can be kept within a more suitable temperature range, thereby ensuring a higher temperature during clothing drying and achieving rapid clothing drying.

[0076] 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.

[0077] Figure 1 is a schematic flowchart of a control method for a garment processing device according to an embodiment of this disclosure. The garment processing device to which this control method is applicable includes at least a receiving cavity for accommodating garments and a drying assembly with an air duct. The air duct is connected to the receiving cavity, and the drying assembly includes an evaporator and an auxiliary cooling structure disposed upstream of the evaporator on the circulating air path of the air duct. The upstream of the evaporator is a position set according to the circulating air path, meaning that according to the circulating air path in the air duct, the circulating air first passes through the auxiliary cooling structure and then through the evaporator. 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. Referring to Figure 1, the control method may include the following steps:

[0078] S110, based on the drying program operation, controls the operation of the auxiliary cooling structure.

[0079] The auxiliary cooling structure is used to pre-cool the circulating air passing through the evaporator. Specifically, when the drying process is running, the container cavity discharges high-temperature and high-humidity steam. The auxiliary cooling structure then cools the high-temperature and high-humidity steam, so that the resulting cooled circulating air with a lower temperature enters the evaporator. This lower-temperature circulating air exchanges heat with the refrigerant flowing in the evaporator, slowing down the rate of temperature rise of the refrigerant.

[0080] The auxiliary cooling structure is located on the circulating air path between the housing and the evaporator, specifically near the upstream end of the evaporator. For example, the auxiliary cooling structure can be located at the front end of the evaporator. This allows the circulating air cooled by the auxiliary cooling structure to pass through the evaporator promptly, effectively mitigating the temperature rise of the refrigerant flowing in the evaporator and better utilizing the cooling effect of the auxiliary cooling structure. The distance between the auxiliary cooling structure and the evaporator can be set according to actual cooling requirements and is not limited here.

[0081] It is 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 through this loop. Furthermore, by utilizing an auxiliary cooling structure to pre-cool the circulating air passing through the evaporator, the subsequent circulating air 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. Compared to scenarios without an auxiliary cooling structure, this method effectively lowers the temperature of the refrigerant circulating in the evaporator, thereby gradually lowering the temperature of the refrigerant circulating in the compressor and condenser, ensuring the refrigerant remains within a suitable temperature range. Therefore, compared to existing technologies that reduce heat source intensity due to excessively high refrigerant temperatures, resulting in longer drying times, the control method for the garment processing equipment provided in this disclosure reduces these adverse effects and facilitates rapid garment drying.

[0082] The control method for the garment processing equipment provided in this disclosure includes: controlling the operation of an auxiliary cooling structure based on the operation of a drying program. Thus, during the drying process, by controlling the operation of the auxiliary cooling structure, the circulating air passing through the evaporator can be pre-cooled, reducing the temperature of the refrigerant in the evaporator. 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, improving drying efficiency, and guaranteeing the drying effect.

[0083] In some embodiments, based on FIG1, before controlling the operation of the auxiliary cooling structure in S110, the following steps are also included:

[0084] Obtain the outlet temperature of the circulating air.

[0085] The outlet temperature is one of the parameters used to determine whether to control the operation of the 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.

[0086] 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 preset cooling conditions, so as to control the operation of the auxiliary cooling structure when it is determined that the preset cooling conditions have been met.

[0087] To address this, the operation of the auxiliary cooling structure in S110 includes the following steps:

[0088] The auxiliary cooling structure is controlled to operate based on the fact that the outlet temperature meets the preset cooling conditions.

[0089] The preset cooling condition is used to determine whether the auxiliary cooling structure needs to be controlled. Specifically, if the outlet temperature meets the preset cooling condition, the auxiliary cooling structure is controlled to cool the circulating air leaving the containment chamber (i.e., the high-temperature and high-humidity steam mentioned above) to form a lower-temperature circulating air. Conversely, if the outlet temperature does not meet the preset cooling condition, the auxiliary cooling structure is not controlled.

[0090] In some embodiments, the preset cooling conditions in the above steps include:

[0091] The outlet temperature is greater than or equal to the input refrigerant temperature of the auxiliary cooling structure.

[0092] It should be noted that the 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 auxiliary cooling structure. For example, the refrigerant circulating in the heat pump drying system may be Freon, while the refrigerant in the auxiliary cooling structure may be water; this is not limited or elaborated upon here.

[0093] The input refrigerant temperature of the auxiliary cooling structure is the temperature of the refrigerant input to the 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.

[0094] In this embodiment, when the outlet temperature of the circulating air is greater than or equal to the input refrigerant temperature of the 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 preset cooling condition, thereby controlling the operation of the auxiliary cooling structure. Conversely, when the outlet temperature of the circulating air is lower than the input refrigerant temperature of the 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 preset cooling condition, and therefore the operation of the 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.

[0095] In some embodiments, the auxiliary cooling structure includes a water-cooled heat exchanger, and the refrigerant is cooling water; based on Figure 1, controlling the operation of the auxiliary cooling structure in S110 specifically includes the following steps:

[0096] Control the cooling water supply to the water-cooled heat exchanger.

[0097] 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.

[0098] For example, when the clothing processing equipment performs the washing operation, the temperature of the tap water can be obtained and recorded. Then, when the clothing processing equipment performs the drying operation, the outlet temperature can be compared with the previously recorded tap water temperature to obtain the 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 preset cooling conditions, thereby controlling the inlet and outlet of tap water in the water-cooled heat exchanger to cool the circulating air leaving the container.

[0099] 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.

[0100] 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, the temperature will not rise too much. This delays the rise in refrigerant temperature 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.

[0101] In some embodiments, based on Figure 1, after controlling the operation of the auxiliary cooling structure in S110, the following steps are further included:

[0102] The auxiliary cooling structure is stopped because the outlet temperature is lower than the input refrigerant temperature of the auxiliary cooling structure.

[0103] 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 preset cooling conditions. In this case, the auxiliary cooling structure is controlled to stop operating, such as controlling the auxiliary cooling structure to stop the intake and discharge of tap water, which is equivalent to shutting down the auxiliary cooling structure.

[0104] It is understandable that when the outlet temperature is lower than the input refrigerant temperature of the 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 auxiliary cooling structure. In this way, water resources are saved and water waste is avoided.

[0105] In some embodiments, based on Figure 1, after controlling the operation of the auxiliary cooling structure in S110, the following steps are further included:

[0106] Step 1: Control the auxiliary cooling structure to alternately turn on and off according to a preset time rhythm, and obtain the operating parameters of the auxiliary cooling structure.

[0107] The preset time interval includes the duration of the auxiliary cooling structure being on and the duration of the auxiliary cooling structure being off. For example, taking the auxiliary cooling structure alternating on and off once as an example, the duration of the auxiliary cooling structure being on can be 1 minute, and the duration of the auxiliary cooling structure being off can be 2 minutes; alternatively, the duration of the auxiliary cooling structure being on can be 3 minutes, and the duration of the auxiliary cooling structure being off can be 2 minutes. In other embodiments, the duration of the auxiliary cooling structure being on and off can also be other values. The time interval for alternating on and off of the auxiliary cooling structure can be set according to the operational requirements of the auxiliary cooling structure, and is not limited here.

[0108] Furthermore, the timing of each alternating on and off of the auxiliary cooling structure can be the same or different. For example, taking two alternating on and off cycles of the auxiliary cooling structure, in scenarios with different timing, when the auxiliary cooling structure first alternates on and off, its on duration can be 1 minute and its off duration can be 2 minutes; when the auxiliary cooling structure alternates 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 cycles can be 3 minutes and the duration of both off cycles can be 1 minute, and there is no limitation here.

[0109] 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 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 auxiliary cooling structure turns on and off during the alternating on / off process.

[0110] For example, only the running time of the auxiliary cooling structure can be obtained, or only the number of times the auxiliary cooling structure is opened and closed can be obtained, or both the running time and the number of times the auxiliary cooling structure is opened and closed can be obtained together; there is no limitation here.

[0111] In this way, by obtaining the operating parameters of the auxiliary cooling structure, it is easier to determine whether the operating parameters meet the relevant conditions of subsequent steps, and to control whether the auxiliary cooling structure stops operating based on the judgment results.

[0112] 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 auxiliary cooling structure to stop operating.

[0113] For example, if the running time of the auxiliary cooling structure reaches a time threshold, or the number of times the auxiliary cooling structure is opened and closed reaches a number threshold, or the running time of the auxiliary cooling structure reaches a time threshold and the number of times the auxiliary cooling structure is opened and closed reaches a number threshold, the auxiliary cooling structure can be controlled to stop running. The number of relevant conditions that should be met when the auxiliary cooling structure stops running is not limited.

[0114] The number of times threshold can be a threshold for the total number of times the auxiliary cooling structure is turned on and off, or it can be a threshold for the number of times the auxiliary cooling structure is turned on and a threshold for the number of times the auxiliary cooling structure is turned off.

[0115] 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 auxiliary cooling structure is turned on and off, if the running time of the auxiliary cooling structure reaches 5 minutes and the total number of times the auxiliary cooling structure is turned on and off reaches 8, then the auxiliary cooling structure is controlled to stop running; or, the auxiliary cooling structure can be controlled to stop running when the running time of the auxiliary cooling structure reaches 5 minutes; or, the auxiliary cooling structure can be controlled to stop running when the total number of times the 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.

[0116] Additionally, when the threshold number is the threshold for the number of times the auxiliary cooling structure is turned on and the threshold number for the number of times the auxiliary cooling structure is turned off, please refer to the corresponding examples above for understanding, which will not be elaborated upon or limited here.

[0117] In some embodiments, FIG2 is a schematic diagram of a garment processing device provided in this disclosure. Referring to FIG2, the garment processing device includes a receiving cavity 21 and a drying assembly 22 with an air duct 221. The drying assembly 22 includes an evaporator 222, an auxiliary cooling structure 223, a compressor 224, a condenser 225, an auxiliary heating structure 226, and a fresh air structure (described exemplarily below). Exemplarily, FIG2 shows the refrigerant circulation loop for the evaporator 222, the compressor 224, and the condenser 225 through the direction of the thick dashed arrows, and the circulation path of the circulating air through the direction of the thin dashed arrows. The compressor 224 is connected between the evaporator 222 and the condenser 225. The auxiliary heating structure 226 can be disposed between the condenser 225 and the receiving cavity 21 to heat up the circulating air that is to pass through the receiving cavity 21, thereby increasing the inlet temperature of the circulating air and improving the drying efficiency.

[0118] It should be noted that the garment processing equipment may also include a housing. Based on this, the spatial relative positions of the compressor 224, evaporator 222, and condenser 225 are illustrated as follows: the compressor 224 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 224.

[0119] Specifically, by using the auxiliary cooling structure 223 to pre-cool the circulating air passing through the evaporator 222, the temperature of the refrigerant in the evaporator 222 is reduced, and the temperature of the refrigerant flowing out of the compressor and the refrigerant in the condenser 225 is also reduced sequentially. In this way, a refrigerant circulation loop with a lower temperature is formed as a whole.

[0120] For example, Figure 3 is a schematic diagram of the drying process of a garment processing device provided in an embodiment of this disclosure, specifically a schematic diagram of temperature changing over time. In this diagram, the horizontal axis X1 represents the running time of the drying program in minutes, and the vertical axis Y1 represents the temperature in degrees Celsius (°C). L31 represents the curve of the temperature of the refrigerant flowing out of the compressor (i.e., the refrigerant discharge temperature) changing over time; L32 represents the curve of the temperature of the circulating air entering the containment chamber (i.e., the circulating air inlet temperature) changing over time; L33 represents the curve of the temperature of the circulating air leaving the containment chamber (i.e., the circulating air outlet temperature) changing over time; L34 represents the curve of the difference between the inlet temperature and the outlet temperature changing over time; R1, R2, R3, and R4 represent the first, second, third, and fourth intervals, respectively.

[0121] It is understandable that temperature sensors, such as negative temperature coefficient 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 discharge temperature, the inlet temperature of the circulating air, and the outlet temperature of the circulating air, respectively.

[0122] 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.

[0123] In some embodiments, based on Figures 1 and 3, the control method further includes the following steps:

[0124] 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.

[0125] 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.

[0126] 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, and can be set according to the clothes drying requirements of the control method provided in the embodiments of this disclosure, and is not limited thereto.

[0127] In some embodiments, based on Figures 1 and 3, the control method further includes the following steps:

[0128] Step 1: Obtain the refrigerant discharge temperature of the compressor.

[0129] 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.

[0130] Step 2: Based on the refrigerant outlet temperature being equal to or greater than the first temperature threshold, control the compressor's operating frequency to be adjusted to the second frequency, which is less than the first frequency.

[0131] Specifically, the constant-speed drying condition can be that the refrigerant discharge temperature is equal to or greater than a first temperature threshold; correspondingly, the first temperature threshold is a temperature threshold for the constant-speed drying scenario of clothing, wherein: constant-speed drying means that the clothing processing equipment continuously and stably dries the clothing at a preset drying speed.

[0132] Specifically, within the first interval, if the refrigerant discharge temperature is determined to be equal to or greater than the first temperature threshold, i.e., the above constant-speed drying conditions are 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.

[0133] 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.

[0134] 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.

[0135] In some embodiments, based on Figures 1 and 3, the control method further includes the following steps:

[0136] Based on the refrigerant outlet temperature being equal to or greater than the second temperature threshold, the compressor's operating frequency is adjusted to a third frequency, where the second temperature threshold is greater than the first temperature threshold and the third frequency is less than the second frequency.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] In some embodiments, based on Figures 1 and 3, the control method further includes the following steps:

[0142] 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. The third temperature threshold is less than the second temperature threshold and greater than the first temperature threshold, so that the auxiliary heating structure continues to operate until the dryness condition is met.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] In view of the defects in the existing drying process, as can be seen from Figure 3 and the above corresponding embodiments, the control method of the clothing processing equipment provided in this disclosure, on the basis of turning on the heater, adaptively adjusts the operating frequency of the compressor to keep the refrigerant outlet temperature of the compressor in a more suitable temperature range, that is, the refrigerant outlet temperature does not exceed 100°C, while the inlet temperature of the circulating air is always maintained at about 80°C.

[0148] Compared to the existing method of shutting off the heater during the drying cycle, the present embodiment controls the heater to remain on during the first and second intervals of the drying cycle until the drying conditions are met, thus ensuring the heat source intensity and maximizing the temperature of the circulating air entering the drum, thereby facilitating the rapid drying of clothes.

[0149] In addition, based on the operation of the auxiliary cooling structure, the operating frequency of the compressor can be adaptively adjusted, which can effectively reduce the temperature of the refrigerant at the corresponding location, so that the refrigerant and the circulating air entering the accommodating cavity are both in a more suitable temperature range, so as to ensure that the heater can continue to be turned on until the drying conditions are met (or until the clothes are dry), without having to turn off the heater due to the high temperature of the refrigerant being pressed out. The specific details of the drying conditions will be explained later.

[0150] In some embodiments, the control method of the garment processing equipment further includes the following steps:

[0151] Step 1: Obtain the inlet and outlet temperatures of the circulating air.

[0152] The inlet temperature is a parameter used to determine whether to stop the auxiliary heating structure, representing the temperature of the circulating air when it enters the containment chamber. Specifically, by obtaining the inlet temperature of the circulating air, it is possible to further determine whether it meets the subsequent dryness criteria, so that when the dryness criteria are met, the auxiliary heating structure can be stopped.

[0153] Step 2: Based on the fact that the inlet temperature and outlet temperature meet the dryness judgment conditions, control the auxiliary heating structure to stop operating.

[0154] The drying condition is related to the inlet and outlet temperatures of the clothes. This drying condition is used to determine whether the auxiliary heating structure needs to be stopped. Specifically, if the inlet and outlet temperatures meet the drying condition, it indicates that the clothes are dry, and the auxiliary heating structure is stopped. Conversely, if the inlet and outlet temperatures do not meet the drying condition, it indicates that the clothes are not dry, and the auxiliary heating structure continues to operate. The specific details of the drying condition will be explained by example later.

[0155] In some embodiments, referring to L34 in FIG3, the difference between the inlet temperature and the outlet temperature can be represented by dT. L34 has a maximum point in the second interval, and the difference corresponding to the 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.

[0156] 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.

[0157] Referring to Figure 3, the control method of the clothing processing equipment provided in this embodiment of the present disclosure achieves that the refrigerant discharge temperature of the compressor does not exceed 100°C and the inlet temperature of the circulating air is always maintained at around 80°C by controlling the compressor and auxiliary heating structure such as the heater to operate simultaneously.

[0158] In some embodiments, the drying component in the garment processing equipment further includes a fresh air structure located upstream of the condenser in the circulating air path of the air duct to pre-cool the circulating air passing through the condenser.

[0159] In some implementations, the auxiliary cooling structure and fresh air structure can be started based on the drying process. The auxiliary cooling structure first cools the circulating air leaving the containment chamber to pre-cool it down, so that the resulting lower-temperature circulating air passes through the evaporator. This prevents the refrigerant flowing in the evaporator from overheating when exchanging heat with the circulating air. Then, the fresh air structure cools the circulating air again, so that the cooled circulating air passes through the condenser. At this point, the refrigerant flowing in the condenser also prevents overheating when exchanging heat with the circulating air. Compared to not having a fresh air structure and auxiliary cooling structure, this method is equivalent to lowering the temperature of the refrigerant flowing in the evaporator and condenser.

[0160] 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, an 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, a fresh air system further 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 overall reduction in the refrigerant temperature within the circulation loop ensures that the refrigerant remains within a suitable temperature range.

[0161] 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.

[0162] The following is an exemplary description of the operation and control methods of the fresh air structure.

[0163] For example, based on Figures 1 and 3, the control method further includes the following steps:

[0164] Step 1: Obtain the first detection temperature.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] It should be noted that the first detected temperature is one of the parameters used to determine whether to control the operation of the fresh air structure. Specifically, based on the operation of the drying program, by obtaining the inlet temperature of the circulating air and / or the refrigerant outlet temperature of the compressor, it is possible to further determine whether they meet the relevant subsequent conditions, so as to control the operation of the fresh air structure when the relevant conditions are determined to be met.

[0169] For example, the first detected temperature may include only the inlet temperature of the circulating air, or only the refrigerant outlet temperature of the compressor, or both the inlet temperature of the circulating air and the refrigerant outlet temperature of the compressor; this is not limited here.

[0170] Step 2: Based on the first detection temperature being greater than the fourth temperature threshold, control the operation of the fresh air structure.

[0171] Among them, the relevant condition mentioned above can be that the first detection temperature is greater than the fourth temperature threshold.

[0172] Specifically, the fourth 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 fourth temperature threshold corresponding to the inlet temperature of the circulating air is usually lower than the fourth temperature threshold corresponding to the refrigerant outlet temperature of the compressor. For example, the fourth temperature threshold corresponding to the inlet temperature can be 60°C, and the fourth temperature threshold corresponding to the refrigerant outlet temperature can be 70°C. In other embodiments, the above fourth temperature thresholds can be set to other values ​​according to the actual pre-cooling requirements, which are not limited here.

[0173] For example, when the first detected temperature is greater than the fourth temperature threshold, that is, when the first detected temperature meets the above relevant conditions, it can be known that the first detected temperature is relatively high. Therefore, there is a cooling demand in the refrigerant circulation loop in the clothing processing equipment, thereby controlling the operation of the fresh air structure to reduce the temperature of the refrigerant in the refrigerant circulation loop based on the fresh air structure, so that the first detected temperature will not be too high. The specific process of the operation of the fresh air structure will be explained later.

[0174] In this embodiment of the present disclosure, when the first detected temperature is greater than the fourth 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 fresh air 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.

[0175] In some embodiments, the fresh air 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.

[0176] Based on this, controlling the operation of the fresh air structure in the above steps specifically includes the following steps:

[0177] The air-cooled heat exchanger is controlled to draw in outside air through the damper.

[0178] 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.

[0179] For example, when the inlet temperature is greater than the fourth temperature threshold, such as 60°C, or the refrigerant outlet temperature is greater than the fourth temperature threshold, such as 70°C, it indicates that the first detection temperature meets the relevant conditions. Then, the air-cooled heat exchanger is controlled to draw in cooler air (i.e., external cold air) from the outside environment through the damper. This external 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 used to cool the refrigerant flowing in the condenser. It can also be understood that in the technical solution provided by this embodiment, the refrigerant temperature rise rate is relatively slow. 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 and compressor along the circulating air path, because the circulating air temperature is low, the refrigerant will not rise too much when exchanging heat with the circulating air, thereby delaying the rise of the refrigerant temperature in the refrigerant circulation loop and reducing the refrigerant temperature rise rate.

[0180] 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.

[0181] It is easy to understand that when the garment processing equipment draws in outside air through the damper, the outside air occupies part of the space in the air duct, so that the air in the air duct with the same volume as the outside air can be discharged from the exhaust port, which helps to stabilize the air pressure in the air duct.

[0182] In some embodiments, the control method of the garment processing equipment further includes the following steps:

[0183] The fresh air structure is shut down if the first detected temperature is lower than the fifth temperature threshold.

[0184] The fifth temperature threshold is lower than the fourth temperature threshold. Furthermore, the fifth temperature threshold typically differs for the inlet temperature of the circulating air and the refrigerant outlet temperature of the compressor.

[0185] Similarly, the fifth temperature threshold corresponding to the inlet temperature of the circulating air is usually lower than the fifth temperature threshold corresponding to the refrigerant outlet temperature of the compressor. For example, based on the premise that the fifth temperature threshold is lower than the fourth temperature threshold, the fifth temperature threshold corresponding to the inlet temperature can be 40°C, and the fifth temperature threshold corresponding to the refrigerant outlet temperature can be 50°C. In other embodiments, the fifth temperature thresholds corresponding to the inlet temperature and the refrigerant outlet temperature can be set to other values, which are not limited here.

[0186] Specifically, when the first detected temperature is less than the fifth temperature threshold, it can be known that the first detected temperature is relatively low. Therefore, there is no need for cooling in the refrigerant circulation loop within the clothing processing equipment. There is no need to reduce the temperature of the refrigerant in the refrigerant circulation loop based on the fresh air structure, and thus the operation of the fresh air structure will not be controlled. That is, the fresh air structure will be stopped. For a detailed understanding of the specific working process of the fresh air structure, please refer to the relevant content above.

[0187] In some embodiments, the control method of the clothing processing equipment further includes the following step: controlling the fresh air structure to stop operating when the operating parameters of the fresh air structure reach a preset parameter threshold.

[0188] The operating parameters include operating time or operating cycle count. The operating cycle count is the number of times the fresh air structure is turned on and off within a preset time. The operating time is the duration of the fresh air structure during operation. Correspondingly, the preset parameter threshold can be a cycle count threshold for the operating cycle count or a time threshold for the operating time.

[0189] It should be noted that garment processing equipment is usually also equipped with a cover structure for switching the on / off state of the fresh air structure. For example, for the air damper, when the cover structure covers the air damper, the air damper is in the closed state; and when the cover structure lifts the air damper, the air damper is in the open state so that the fresh air structure can operate.

[0190] For example, the duration of each opening of the fresh air structure can be 1 minute, and the duration of each closing can be 2 minutes. Taking this as an example, the fresh air structure can alternately open and close 5 times within a preset time according to the above duration. Alternatively, the fresh air structure can be opened 2 times and then closed 3 times. In other embodiments, the fresh air structure can also be controlled to operate at other operating cycles, which are not limited here.

[0191] Specifically, after controlling the operation of the fresh air structure, if the fresh air structure, such as the damper, is controlled to open and close alternately according to a preset number of operating beats, then when the number of operating beats of the fresh air structure reaches the beat threshold, such as when the number of times the fresh air structure alternates opening and closing reaches 5 times, the fresh air structure can be controlled to stop operating; or, when the operating time of the fresh air structure reaches the time threshold, such as 2 minutes, 4 minutes or other durations, the fresh air structure can be controlled to stop operating. Here, the specific size of the beat threshold and the time threshold is not limited.
