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

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

[0054] Figure 5 is a schematic diagram of another garment processing device provided in an embodiment of this disclosure. Detailed Implementation

[0055] 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.

[0056] 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.

[0057] The control method of the clothing processing equipment provided in the embodiments of this disclosure will be analyzed below with reference to the accompanying drawings.

[0058] The technical solution provided in this disclosure is applicable to a garment processing device with a accommodating cavity for accommodating garments. In practical applications, the garment processing device further includes an evaporator, a compressor, a condenser, an auxiliary heating structure, and an air duct for circulating air. The evaporator, compressor, and condenser constitute a heat pump drying system capable of circulating refrigerant, facilitating heat exchange between the above structure and the circulating air during the drying process. The evaporator is located between the accommodating cavity and the compressor, and the auxiliary heating structure is positioned between the compressor and the accommodating cavity to assist in heating the circulating air entering the accommodating cavity. Exemplarily, the auxiliary heating structure can be a heater; the garment processing device can be a heat pump dryer, a heat pump washer-dryer combo, or other heat pump drying equipment, and is not limited thereto.

[0059] The control method for the clothing processing equipment provided in this embodiment detects the temperature to determine if the preset drying conditions are met, thereby determining that the clothing is dry. This achieves accurate perception of the degree of drying of the clothing, ensuring effective drying and improving the drying effect.

[0060] In some embodiments, after the drying program is started, the compressor and auxiliary heating structure can be controlled to operate first, with the compressor operating at a first frequency to quickly increase the drying temperature within a short time. Furthermore, when the compressor outlet temperature exceeds a preset temperature, the auxiliary heating structure can be controlled to continue operating or to be turned off. Specifically, when the auxiliary heating structure is operating, the compressor operates at a second frequency, and when the auxiliary heating structure is turned off, the compressor operates at a third frequency, where both the second and third frequencies are lower than the first frequency, and the third frequency is greater than or equal to the second frequency. This configuration achieves stable, constant-speed drying for clothing.

[0061] In some embodiments, by obtaining the upper limit of the temperature difference between the first detection temperature and the second detection temperature, the temperature difference variation value, and the preset drying temperature difference change amount, it is determined that the temperature difference variation value is less than or equal to the difference between the upper limit of the temperature difference and the preset drying temperature difference change amount, thereby determining that the preset drying conditions are met, thus realizing the accurate judgment of the degree of drying of clothes, thereby ensuring that clothes can be effectively dried.

[0062] In some embodiments, based on determining that the auxiliary heating structure is off, a first duration for which the auxiliary heating structure remains off is obtained, and the first duration is determined to be greater than the first monitoring duration; and / or, based on determining that the compressor is running at a second frequency, a second duration for which the compressor runs at a second frequency is obtained, and the second duration is determined to be greater than the second monitoring duration, which is beneficial for subsequently obtaining an accurate upper limit value of the temperature difference and ensuring the accuracy of the judgment on the degree of drying of clothes.

[0063] In some embodiments, by acquiring ambient temperature, clothing weight, current operating program, and preset correlation, wherein the preset correlation is the interrelationship between ambient temperature, clothing weight, current operating program, and preset drying temperature change, and then based on ambient temperature, clothing weight, current operating program, and preset correlation, the preset drying temperature difference change corresponding to the three is determined, thereby achieving adaptive adjustment of the preset drying temperature change and helping to ensure the accuracy of clothing drying detection.

[0064] In some embodiments, before determining the clothes drying time, a high-temperature protection mode can be entered. Specifically, the third detection temperature of the compressor outlet can be obtained. If the third detection temperature is equal to or greater than the first temperature threshold, the compressor is controlled to run at a third frequency lower than the second frequency. When the third detection temperature is equal to or less than the second temperature threshold, the compressor is controlled to run at the second frequency, wherein the second temperature threshold is less than the first temperature threshold.

[0065] Alternatively, a low-temperature protection mode can be entered. Specifically, the fourth ambient temperature at the evaporator location and the current operating frequency of the compressor can be obtained. If the fourth ambient temperature is equal to or less than the third temperature threshold and the current operating frequency is greater than the reference frequency, the compressor is controlled to operate at the reference frequency. If the fourth ambient temperature is equal to or less than the third temperature threshold and the current operating frequency is less than the reference frequency, the compressor is controlled to continue operating at the current operating frequency. Alternatively, if the fourth ambient temperature is equal to or greater than the fourth temperature threshold, the compressor is controlled to operate at the current operating frequency, where the fourth temperature threshold is greater than the third temperature threshold.

[0066] Specifically, when the detection duration of the compressor restarting at the second frequency is greater than or equal to the third monitoring duration, the clothes are determined to be dry. This enriches the methods for judging the degree of clothes drying.

[0067] The control method and equipment for the garment processing device provided in this disclosure will be described exemplarily below with reference to the accompanying drawings.

[0068] 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. The control method can be executed by a control device, such as a 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:

[0069] S110. Obtain the detected temperature during the drying process.

[0070] The detected temperatures include a first detected temperature at the inlet of the accommodating cavity and a second detected temperature at the outlet of the accommodating cavity. Specifically, the first detected temperature is the temperature of the circulating air just before it passes through the accommodating cavity, and the second detected temperature is the temperature of the circulating air when it leaves the accommodating cavity (or the temperature of the circulating air leaving the accommodating cavity). It should be noted that during the drying process, the first detected temperature is usually higher than the second detected temperature, and the rate of increase of the first detected temperature is faster than that of the second detected temperature. For example, the first detected temperature may be 75°C, and the second detected temperature may be 68°C; these are not limited here.

[0071] Thus, during the drying process, by acquiring the detection temperature at the corresponding location, such as the first detection temperature at the inlet of the container cavity and the second detection temperature at the outlet of the container cavity, it is possible to further determine whether the subsequent preset drying conditions are met, so as to achieve real-time and accurate judgment of the degree of drying of the clothes.

[0072] S120: Based on the detected temperature, determine that the preset drying conditions are met, and determine that the clothes are dry.

[0073] Among them, the preset drying conditions are used to judge the degree of drying of clothes during the operation of the drying program.

[0074] Specifically, if the preset drying conditions are met based on the first and second detection temperatures, the clothes are determined to be dry; otherwise, if the preset drying conditions are not met based on the first and second detection temperatures, the clothes are determined to be not dry.

[0075] In this way, by acquiring the first and second detection temperatures and determining whether the preset drying conditions are met, the degree of drying of the clothes can be accurately perceived, avoiding the problem in related technologies where the accuracy of the degree of drying of clothes is not high due to structural limitations or other factors, resulting in poor drying of clothes.

[0076] The control method for a clothing processing device provided in this embodiment includes: acquiring a detected temperature during the drying process, the detected temperature including a first detected temperature at the inlet of the accommodating cavity and a second detected temperature at the outlet of the accommodating cavity; determining that the preset drying conditions are met based on the detected temperature, and thus determining that the clothing is dry. In this way, by determining that the preset drying conditions are met through temperature detection, and then determining that the clothing is dry, accurate perception of the degree of drying of the clothing is achieved, ensuring effective drying of the clothing and improving the drying effect.

[0077] For example, Figure 2 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 the temperature changing over time. In the figure, 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). L21 represents the curve of the temperature of the refrigerant flowing from the compressor changing over time; L22 represents the curve of the temperature of the circulating air just before it passes through the receiving cavity changing over time; L23 represents the curve of the temperature of the circulating air leaving the receiving cavity changing over time; L24 represents the curve of the difference between the first and second detected temperatures changing over time; R1, R2, R3, and R4 represent the first, second, third, and fourth intervals, respectively.

[0078] 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 condenser cavity, and between the evaporator and the condenser cavity, to sense the temperature of the refrigerant flowing out of the compressor, the temperature of the circulating air just before it passes through the condenser cavity, and the temperature of the circulating air leaving the condenser cavity.

[0079] Specifically, in the first, second, third, and fourth intervals, the temperature of the refrigerant flowing from the compressor, the first detection temperature, the second detection temperature, and the difference between the first and second detection temperatures all exhibit corresponding trends. For example, regarding the first detection temperature, it gradually increases during the initial stage of the drying program, such as in the first interval, and reaches a relatively stable equilibrium temperature during the later stages of the drying program, such as in the second interval. As for the second detection temperature, it shows a continuous upward trend throughout the entire process from the start to the end of the drying program.

[0080] In view of this, the degree of drying of clothes during the drying process can be determined by the changing trend of the difference between the first detection temperature and the second detection temperature, so as to ensure that the clothes can be effectively dried. In this regard, the control methods related to the drying process will be described in detail below through various embodiments.

[0081] In some embodiments, based on Figures 1 and 2, the control method further includes the following steps:

[0082] The operation of the compressor and auxiliary heating structure is controlled based on the start of the drying program.

[0083] Both the compressor and the auxiliary heating structure are heat sources, and the compressor operates at the first frequency.

[0084] Specifically, after the drying program is started, preferably during the initial stage of the drying program, i.e., the first interval, the compressor and the auxiliary heating structure can be controlled to run simultaneously, with the compressor running at a first frequency, thereby increasing the heat source intensity and thus enabling the drying temperature to be raised as quickly as possible in a short time. In other embodiments, the auxiliary heating structure can be controlled to turn on after the compressor has run at the first frequency for a preset time, such as 1 minute, 2 minutes or other duration, so that the auxiliary heating structure and the compressor run together. Here, the timing of the compressor and the auxiliary heating structure turning on is not limited.

[0085] It should be noted that the first frequency is a high frequency. For example, the first frequency can be 60Hz-70Hz, such as 60Hz, 65Hz or other frequencies. In other embodiments, the first frequency can also be other frequencies or frequency ranges known to those skilled in the art. It can be set according to the clothing drying requirements of the control method provided in the embodiments of this disclosure, and is not limited here.

[0086] In some embodiments, based on Figures 1 and 2, the control method further includes the following steps:

[0087] If the compressor outlet temperature is higher than the preset temperature, the auxiliary heating structure can be kept running or shut down.

[0088] When the compressor outlet temperature is higher than the preset temperature, the drying cycle can enter the second zone.

[0089] The compressor outlet temperature is the temperature of the refrigerant flowing out of the compressor. For example, the preset temperature can be 80°C, 85°C, or other temperatures. Preferably, taking 85°C as an example, when the compressor outlet temperature is determined to be greater than 85°C, the auxiliary heating structure can be controlled to continue operating, or the auxiliary heating structure can be controlled to be turned off, i.e., stop operating. The value of the preset temperature is not limited here.

[0090] Specifically, when the auxiliary heating structure is in operation, the compressor operates at a second frequency; when the auxiliary heating structure is off, the compressor operates at a third frequency, and both the second and third frequencies are lower than the first frequency. It is understood that the second and third frequencies may be equal or unequal.

[0091] For example, if the second frequency and the third frequency are equal, the second frequency and the third frequency can be 45Hz-55Hz. Specifically, the second frequency and the third frequency can both be 50Hz, 55Hz or other frequencies. If the second frequency and the third frequency are not equal, the second frequency can be greater than the third frequency, or the second frequency can be less than the third frequency. The second frequency and the third frequency can be adaptively set according to the clothes drying requirements of the embodiments of this disclosure, and are not limited here.

[0092] It should be noted that while the compressor operates at a second (or third) frequency lower than the first frequency, the auxiliary heating structure is kept running or turned off, which can achieve stable constant-speed drying for clothes.

[0093] Furthermore, the operating status of the auxiliary heating structure is also related to the type of the current drying program. Specifically, within the second interval, it can be further determined, based on the type of the current drying program, whether to control the auxiliary heating structure and the compressor to continue operating together, or to control the auxiliary heating structure to be turned off and only control the compressor to continue operating.

[0094] For example, the drying program may include a fast drying program and a slow drying program. For the fast drying program, the auxiliary heating structure and the compressor can be controlled to run together in the second zone, thereby ensuring the heat source intensity, reducing the drying time of clothes, and facilitating the rapid drying of clothes. For the slow drying program, the auxiliary heating structure can be controlled to turn off in the second zone, and only the compressor can be controlled to continue running, thereby reducing the heat source intensity, extending the drying time of clothes, and achieving the drying of clothes at a slower speed. The operating status of the auxiliary heating structure and the compressor in the second zone can be set according to the type of the current drying program, which is not limited here.

[0095] In some embodiments, the third frequency in the above steps is greater than or equal to the second frequency.

[0096] Preferably, in this embodiment of the disclosure, the third frequency is greater than or equal to the second frequency. For example, taking the third frequency being greater than the second frequency as an example, the third frequency can be 55Hz and the second frequency can be 45Hz. Alternatively, the third frequency and the second frequency can also be other values ​​that satisfy this relative size relationship. The specific values ​​of the third frequency and the second frequency are not limited here.

[0097] In some embodiments, based on Figures 1 and 2, step S120 determines whether the preset drying conditions are met based on the detected temperature, specifically including the following steps:

[0098] Step 1: Based on the detected temperature, obtain the upper limit of the temperature difference between the first and second detected temperatures, the temperature difference variation value, and the preset dryness judgment temperature difference change amount.

[0099] The upper limit of the temperature difference is used to characterize the maximum temperature difference formed by the first detection temperature and the second detection temperature within the second interval.

[0100] Specifically, referring to L24 in Figure 2, in the early stage of the second interval, the temperature difference between the first and second detection temperatures does not continue to rise, but fluctuates randomly. To facilitate the determination of the upper limit of the temperature difference, the temperature difference value at any moment in the second interval can be saved and recorded. When a certain temperature difference value is determined to be the largest value in the previous historical records or greater than any temperature difference value in the historical records, and L24 shows a downward trend after that temperature difference value, then the temperature difference value is determined to be the maximum temperature difference value, that is, the upper limit of the temperature difference (see the highest point of L24 in the second interval).

[0101] For example, if the temperature difference between the first and second detection temperatures obtained at a preset time within the second interval is 28℃, 29℃, 30℃, 28℃, and 30℃ respectively, and 30℃ is determined to be the largest value in the previous historical records, and L24 shows a decreasing trend when the temperature difference between the first and second detection temperatures is subsequently obtained, then 30℃ is determined to be the upper limit of the temperature difference.

[0102] It is easy to understand that the temperature difference variation value is the real-time changing temperature difference value (or temperature range). For example, continuing to refer to L24 in Figure 2, after reaching the maximum temperature difference, it will gradually decrease to a certain temperature difference over time; for this, the temperature difference variation value can be any temperature difference within the second interval, such as: the temperature difference variation value can be the maximum temperature difference, the minimum temperature difference, or other temperature differences between the maximum and minimum temperature differences, which are not limited here.

[0103] Among them, the preset drying temperature difference change is the main parameter used to determine whether the preset drying conditions are met. Specifically, based on the operation of the drying program, by obtaining the upper limit of the temperature difference, the temperature difference variation value, and the preset drying temperature difference change, it is possible to further determine whether the subsequent preset drying conditions are met, so that the clothes can be dried when it is determined that the preset drying conditions are met.

[0104] Step 2: Based on the difference between the temperature difference variation value and the preset drying temperature difference variation value, determine whether the preset drying conditions are met.

[0105] Conversely, if the temperature difference variation is greater than the difference between the upper limit of the temperature difference and the preset temperature difference variation for drying, then the preset drying conditions are not met, and the clothes are determined to be not dried.

[0106] The preset drying temperature difference variation depends at least on the type of drying program (or the currently running program), the weight of the clothes, and the ambient temperature. The preset drying temperature difference variation is adaptively adjusted according to the type of drying program, the weight of the clothes, and the ambient temperature, thereby ensuring that the clothes can be effectively dried. The selection process of the preset drying temperature difference variation will be illustrated later and will not be repeated here.

[0107] It is easy to understand that, preferably, in the embodiments of this disclosure, other temperature differences after the upper limit of the temperature difference are selected as the temperature difference variation value to ensure the drying effect of the clothes.

[0108] For example, referring to L24 in Figure 2, the preset temperature difference change can be 3.2℃, and the upper limit of the temperature difference can be 29.4℃. It can be seen that the difference between the two is 26.2℃. Therefore, the temperature difference change value after the upper limit of the temperature difference is compared with 26.2℃ in real time. When a temperature difference value after the upper limit of the temperature difference is detected to be equal to 26.2℃, it is determined that the preset drying conditions are met, and then it is determined that the clothes are dry at this time.

[0109] Specifically, the temperature difference between the inlet and outlet of the accommodating cavity can be represented by dT. The maximum temperature difference (or upper limit of temperature difference) corresponding to the highest point of L24 in the second interval can be represented by dT_max. The preset temperature difference change can be represented by β. In this regard, after decreasing by β relative to dT_max, the corresponding temperature difference change value (i.e., dT) is obtained. This indicates that the preset drying conditions are met, indicating that the clothes have been dried. The second interval of the drying process ends, and the third interval begins.

[0110] It should be noted that although existing garment processing equipment typically uses temperature sensing to determine the degree of drying, such as judging the dryness of clothes after a certain temperature is reached, the fixed values ​​set in these technical solutions are relatively absolute and singular. Therefore, during the drying process, they cannot sensitively respond to changes in the ambient temperature and are easily affected by other variables such as the tolerance of the auxiliary heating structure and the accuracy of the negative temperature coefficient thermistors. For example, if the temperature reading of the negative temperature coefficient thermistor installed at the entrance of the accommodating cavity is too high or too low, the temperature will not reach the actual fixed value. As a result, existing garment processing equipment does not accurately judge the degree of drying of clothes, leading to poor drying.

[0111] To address this, the technical solution provided in this disclosure determines that the clothes are dry when the temperature difference variation reaches the difference between the upper limit of the temperature difference and the preset dryness judgment temperature difference change. Compared with the existing technical solution that judges clothes dryness by reaching a fixed temperature, the upper limit of the temperature difference and the preset dryness judgment temperature difference change in this disclosure can be adaptively changed with various variable factors in the drying process. After the preset dryness judgment temperature difference change decreases relative to the upper limit of the temperature difference, the corresponding temperature difference variation value is obtained to judge that the clothes are dry. In this way, the drying detection of clothes is achieved by using dynamic relative values, which is not easily affected by changes in ambient temperature and deviations of components such as the tolerance of auxiliary heating structure. This allows for accurate perception of the degree of drying of clothes and ensures effective drying of clothes.

[0112] In some embodiments, based on Figures 1 and 2, before obtaining the upper limit of the temperature difference in the above steps, the following steps are also included:

[0113] Step 1: Ensure the auxiliary heating structure is turned off.

[0114] Specifically, as shown in Figure 2, for the second interval, the auxiliary heating structure can be controlled to be turned off, and the compressor can be operated at the second frequency, so as to determine the upper limit of the temperature difference based on the above working state of the auxiliary heating structure and / or the compressor.

[0115] Step 2: Obtain the first duration of continuous shutdown of the auxiliary heating structure, and determine that the first duration is longer than the first monitoring duration.

[0116] The first monitoring duration is the duration used to measure the length of time the auxiliary heating structure remains continuously off. For example, the first duration may be 8 minutes, 10 minutes, 12 minutes, or other durations; the first monitoring duration is usually 10 minutes or more, such as 10 minutes, 13 minutes, 15 minutes, or other durations, which are not limited here.

[0117] It should be noted that when the first duration is longer than the first monitoring duration, the upper limit of the temperature difference is determined to ensure the stability of temperature sensing and thus facilitate obtaining an accurate and stable upper limit of the temperature difference. For example, taking a first monitoring duration of 10 minutes as an example, if the first duration is 8 minutes, then the first duration is shorter than the first monitoring duration, and therefore the upper limit of the temperature difference will not be calculated in this case; conversely, if the first duration is 12 minutes, then the first duration is longer than the first monitoring duration, and therefore the upper limit of the temperature difference can be calculated.

[0118] It is understandable that the temperature of the circulating air is relatively high when it leaves or enters the drying chamber, in order to heat the clothes for drying. Since the temperature of the circulating air is related to the intensity of the heat source, its temperature will fluctuate drastically when the compressor's operating frequency changes or the auxiliary heating structure is turned off, thus affecting the stability of temperature sensing and leading to instability. To address this, calculating the upper limit of the temperature difference only after the auxiliary heating structure has been continuously turned off for a period longer than the initial monitoring period—for example, calculating the upper limit of the temperature difference 10 minutes after the auxiliary heating structure has been turned off—can ensure the stability of temperature sensing and improve the accuracy of the obtained upper limit of the temperature difference.

[0119] In conjunction with the corresponding embodiments above, before obtaining the upper limit of the temperature difference in the above steps, the following steps are also included:

[0120] Step 1: Determine that the compressor is running at the second frequency.

[0121] Specifically, as shown in Figure 2, for the second interval, the compressor can be controlled to operate at a second frequency to determine the upper limit of the temperature difference based on the compressor's above operating state.

[0122] Step 2: Obtain the second duration of continuous operation of the compressor at the second frequency, and determine that the second duration is longer than the second monitoring duration.

[0123] The second monitoring duration is the duration used to measure the length of time the compressor operates continuously at a second frequency for a second duration. For example, the second monitoring duration may be 10 minutes or more, 15 minutes or more, or other duration ranges; the second duration may be 9 minutes, 11 minutes, 12 minutes, or other durations, and is not limited herein.

[0124] In addition, the second monitoring duration may be the same as or different from the first monitoring duration. For example, if the first monitoring duration is 10 minutes or more, specifically 10 minutes, the second monitoring duration may also be 10 minutes. Alternatively, the second monitoring duration may be 15 minutes, 16 minutes, or other durations different from the first monitoring duration, which will not be elaborated or limited here.

[0125] It should be noted that when the second duration is longer than the second monitoring duration, the upper limit of the temperature difference is determined to ensure the stability of temperature sensing, thereby facilitating the acquisition of an accurate and stable upper limit of the temperature difference.

[0126] For example, if the second monitoring duration is 10 minutes, and the second duration is 9 minutes, then the second duration is less than the second monitoring duration, so the upper limit of the temperature difference will not be calculated. Conversely, if the second duration is 13 minutes, then the second duration is greater than the second monitoring duration, so the upper limit of the temperature difference can be calculated.

[0127] Similarly, given that the temperature of the circulating air changes drastically with the intensity of the heat source, thus affecting the stability of temperature sensing and causing instability, to address this, the upper limit of the temperature difference is calculated only after the compressor has been running at the second frequency for a second duration longer than the second monitoring duration. For example, the upper limit of the temperature difference is calculated only after the compressor has been running at the second frequency for 10 minutes. This ensures the stability of temperature sensing and improves the accuracy of the obtained upper limit of the temperature difference.

[0128] In some embodiments, based on Figures 1 and 2, obtaining the preset temperature difference change in the above steps specifically includes the following steps:

[0129] Step 1: Obtain ambient temperature, clothing weight, currently running program, and preset associations.

[0130] For example, the garment handling equipment may install sensors with temperature sensing and / or weight sensing functions at the corresponding locations. For example, for sensors with temperature sensing functions, a temperature sensor or a temperature and humidity sensor may be installed at the corresponding locations. Based on this, the current ambient temperature and the weight of the garment can be sensed by the relevant sensors and transmitted to the control device so that the control device can obtain the current ambient temperature and the weight of the garment. The specific type of sensor is not limited here.

[0131] The preset correlation is the interrelationship between ambient temperature, clothing weight, operating program, and preset dryness temperature change. For example, the preset correlation may be a lookup table, correlation formula, or other form of correlation known to those skilled in the art, established based on ambient temperature, clothing weight, operating program, and preset dryness temperature change, in order to determine the preset dryness temperature change corresponding to the ambient temperature, clothing weight, and current operating program through the preset correlation; this is not limited here.

[0132] Step 2: Based on the ambient temperature, the weight of the clothing, the current operating program, and the preset correlation, determine the preset temperature difference change.

[0133] For example, regarding ambient temperature, ambient temperature can be divided into high ambient temperature, normal ambient temperature, and low ambient temperature. For instance, high ambient temperature can be greater than 27°C, normal ambient temperature can be 18°C ​​to 27°C, and low ambient temperature can be less than 18°C. Regarding the weight of clothing, the weight of clothing can be divided into less than 2kg, less than 3kg, less than 5kg, and less than 7kg.

[0134] For the current operating program, the operating program can be divided into a 90-minute wash-dry program, a 1 / 3 / 5kg quick-dry program, a standard program, a night program, and a low-temperature program (referring to the program with low temperature inside the cavity). Based on the above divisions, a subsequent lookup table can be formed. In addition, other divisions can be made according to the drying needs of the clothes, such as ambient temperature, weight of the clothes, and the current operating program, which are not limited here.

[0135] For example, a wash-dry 90 program represents a program where the total time for washing and drying clothes is 90 minutes, and a 1 / 3 / 5kg quick-dry program represents a program for quickly drying clothes weighing around 1kg, 3kg, or 5kg. The working content of other programs can be understood in conjunction with existing drying programs, and will not be elaborated here.

[0136] For example, preferably, Table 1 is a preset lookup table for the change in dry temperature provided in an embodiment of this disclosure.

[0137] Table 1

[0138] As shown in Table 1, Table 1 shows the changes in preset dry temperature differences for different operating programs and different clothing weights, based on an ambient temperature of high ambient temperature.

[0139] The first column, “High ambient temperature,” represents the current ambient temperature as high. “Wash & Dry 90,” “1 / 3 / 5k Quick Dry,” “Standard,” “Night,” and “Low temperature” represent different types of programs. The second row, “Below 2k,” “Below 3k,” “Below 5k,” and “Below 7k,” represents different ranges of clothing weight. The numbers between different types of programs and different ranges of clothing weight represent the changes in the preset drying temperature difference.

[0140] It should be noted that Table 1 is a preferred search scheme for the preset dry temperature difference change amount provided by the embodiments of this disclosure, so as to set the corresponding preset dry temperature difference change amount according to different types of programs and different ranges of clothing weight when the ambient temperature is high, so as to realize the adaptive adjustment of the preset dry temperature difference change amount.

[0141] For example, preferably, Table 2 is another preset lookup table for the change in dry temperature provided in the embodiments of this disclosure.

[0142] Table 2

[0143] As shown in Table 2, Table 2 illustrates the changes in preset drying temperature differences for different operating programs and different garment weights, assuming an ambient low temperature. The first column, "Ambient Low Temperature," represents the current ambient low temperature; "Wash & Dry 90," "1 / 3 / 5K Quick Dry," "Standard," "Night," and "Low Temperature" represent different program types. The second row, "Below 2K," "Below 3K," "Below 5K," and "Below 7K," represent different ranges of garment weights. The numbers between different program types and different garment weight ranges represent the changes in preset drying temperature differences.

[0144] It should be noted that Table 2 is another preferred search scheme for the preset dry temperature difference change amount provided by the embodiments of this disclosure, so as to set the corresponding preset dry temperature difference change amount according to different types of programs and different ranges of clothing weight when the ambient temperature is low, so as to realize the adaptive adjustment of the preset dry temperature difference change amount.

[0145] In some embodiments, by combining Tables 1 and 2, the obtained ambient temperature, clothing weight, and current operating program are substituted into Table 1 or Table 2, and the corresponding preset drying temperature difference change is determined based on the substituted ambient temperature, clothing weight, and operating program. Thus, this embodiment of the present disclosure adaptively adjusts the preset drying temperature difference change based on ambient temperature, clothing weight, and current operating program, improving the accuracy of sensing the degree of clothing drying and thereby ensuring the drying effect of the clothing.

[0146] In some embodiments, based on Figures 1 and 2, before determining that the clothes are to be dried in S120, the following steps are also included:

[0147] Step 1: Obtain the third detection temperature at the compressor outlet.

[0148] The third detection temperature is the temperature of the refrigerant flowing from the compressor. Specifically, during the drying process, the third detection temperature at the compressor outlet can be obtained, and based on the magnitude of the third detection temperature, it can be determined whether the compressor's operating frequency needs to be adjusted to ensure that the temperature at the corresponding location is within a suitable range, reducing the adverse effects caused by excessively high temperatures at the corresponding location and ensuring the drying effect of the clothes.

[0149] Step 2: Based on the third detected temperature being equal to or greater than the first temperature threshold, control the compressor to operate at a third frequency, where the third frequency is less than the second frequency; or, based on the third detected temperature being equal to or less than the second temperature threshold, control the compressor to operate at a second frequency, where the second temperature threshold is less than the first temperature threshold.

[0150] Specifically, in conjunction with the corresponding steps above, when the temperature difference change value is obtained by decreasing β relative to dT_max in the second interval, if the third detection temperature is determined to be equal to or greater than the first temperature threshold, it indicates that the third detection temperature is high. Then, the compressor is controlled to run at a third frequency lower than the second frequency, which is equivalent to entering the high temperature protection mode of the compressor, thereby reducing the third detection temperature at the compressor outlet.

[0151] Correspondingly, as the compressor operating frequency decreases, the third detection temperature at the compressor outlet also decreases. When the third detection temperature is equal to or less than the second temperature threshold, it indicates that the third detection temperature at the compressor outlet is within a suitable temperature range. Then, the compressor is controlled to run at the second frequency again, which is equivalent to deactivating the compressor's high-temperature protection mode.

[0152] For example, the first temperature threshold can be 95°C, the second temperature threshold can be 90°C, the second frequency can be 50Hz, and the third frequency can be 40Hz. Specifically, if the compressor's operating frequency is 50Hz, and the third detected temperature is determined to be equal to or greater than 95°C, the compressor's operating frequency is adjusted to 40Hz. After the compressor has been running at 40Hz for a period of time, if the third detected temperature is determined to be equal to or less than 90°C, the compressor's operating frequency is restored to 50Hz. In other embodiments, the first temperature threshold, the second temperature threshold, the second frequency, and the third frequency can be set to other values, as long as the above magnitude relationship is satisfied, which is not limited here.

[0153] In some embodiments, FIG3 is a schematic diagram of a garment processing device provided in this disclosure. Referring to FIG3, the garment processing device includes a receiving cavity 31, a compressor 32, an auxiliary heating structure 33, and an evaporator 34. In addition, in actual application, the garment processing device is also provided with a condenser 35 located between the compressor 32 and the auxiliary heating structure 33. In FIG3, the direction of the refrigerant circulation loop for the evaporator 34, the compressor 32, and the condenser 35 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. The evaporator 34 is located between the receiving cavity 31 and the compressor 32, and the auxiliary heating structure 33 is disposed between the condenser 35 and the receiving cavity 31 to heat up the circulating air passing through the receiving cavity 31, thereby increasing the temperature of the circulating air and improving the drying efficiency.

[0154] In some embodiments, based on Figures 1 and 2, before determining that the clothes are to be dried in S120, the following steps are also included:

[0155] Step 1: Obtain the fourth ambient temperature and the current operating frequency of the compressor at the location of the evaporator.

[0156] The fourth temperature detection is actually the ambient temperature around the evaporator. Specifically, during the drying process, the fourth temperature detection relative to the environment at the evaporator location and the current operating frequency of the compressor can be obtained. By combining the fourth temperature detection and the current operating frequency of the compressor, it can be determined whether the operating frequency of the compressor needs to be adjusted to ensure that the temperature at the corresponding location is within a suitable temperature range, thereby reducing the adverse effects caused by excessively low temperatures at the corresponding location and improving the safety performance of the clothing processing equipment.

[0157] It is understandable that a sensor with temperature sensing function, such as a temperature sensor or a temperature and humidity sensor, can be installed on the evaporator to sense the ambient temperature around the evaporator, i.e., the fourth detection temperature.

[0158] Step 2: Based on the fourth detected temperature being equal to or less than the third temperature threshold, and the current operating frequency being greater than the reference frequency, control the compressor to operate at the reference frequency; or, based on the fourth detected temperature being equal to or less than the third temperature threshold, and the current operating frequency being less than the reference frequency, control the compressor to continue operating at the current operating frequency.

[0159] Alternatively, based on the fourth detected temperature being equal to or greater than the fourth temperature threshold, the compressor is controlled to operate at the current operating frequency, where the fourth temperature threshold is greater than the third temperature threshold.

[0160] Among them, when the fourth detection temperature is equal to or less than the third temperature threshold, the reference frequency is used as a benchmark to determine whether the compressor needs to adjust its current operating frequency.

[0161] Specifically, in conjunction with the corresponding steps above, within the second interval, when the temperature difference change value is obtained by decreasing β relative to dT_max, if the fourth detection temperature is determined to be equal to or less than the third temperature threshold, it indicates that the fourth detection temperature is low. At the same time, if the current operating frequency of the compressor is greater than the reference frequency, the compressor is controlled to operate at the reference frequency, which is equivalent to entering the low temperature protection mode of the compressor, thereby increasing the fourth detection temperature at the evaporator location.

[0162] Alternatively, if the current operating frequency of the compressor is less than the reference frequency when the fourth detection temperature is equal to or less than the third temperature threshold, the compressor is controlled to continue operating at the current operating frequency. This indicates that the current operating frequency of the compressor is more appropriate when the fourth detection temperature is lower, so there is no need to adjust the current operating frequency of the compressor.

[0163] For example, if it is determined that the fourth detection temperature is equal to or greater than the fourth temperature threshold, indicating that the fourth detection temperature is not too low, the compressor is controlled to run at the current operating frequency, which is equivalent to deactivating the compressor's low temperature protection mode.

[0164] The fourth temperature threshold is greater than the third temperature threshold. For example, preferably, taking a third temperature threshold of -4℃, a fourth temperature threshold of 0℃, and a reference frequency of 50Hz as an example, specifically: when the fourth detection temperature is equal to or less than -4℃, if the compressor's current operating frequency is less than 50Hz (e.g., 45Hz), the compressor is controlled to continue operating at the current frequency. Conversely, if the compressor's current operating frequency is greater than 50Hz (e.g., 60Hz), the compressor is controlled to operate at 50Hz, i.e., enter the compressor's low-temperature protection mode, until the fourth detection temperature is equal to or greater than 0℃, at which point the compressor's operating frequency is controlled to return to 60Hz, i.e., the compressor's low-temperature protection mode is deactivated.

[0165] Based on the above examples, it can be seen that in other embodiments, the current operating frequency of the compressor, the third temperature threshold, the fourth temperature threshold, and the reference frequency can be set to other values, which can be adjusted according to the clothing drying requirements of the embodiments of this disclosure, and are not limited here.

[0166] It is easy to understand that when the fourth detection temperature is low, the refrigerant pipes of the evaporator are prone to frost formation, which can easily lead to safety problems during the operation of the clothing processing equipment. To address this, by performing the above-mentioned steps for the compressor, the ambient temperature around the evaporator is further increased, making it less prone to frost formation and thus avoiding the above-mentioned safety problems, thereby improving the safety performance of the clothing processing equipment.

[0167] In some embodiments, based on Figures 1 and 2, before determining that the preset drying conditions are met based on the detected temperature in step S120, the following steps are also included:

[0168] Obtain the detection duration for the compressor to restart at the second frequency, and determine that the detection duration is greater than or equal to the third monitoring duration.

[0169] The third monitoring duration is used to determine whether the clothes are dry. It should be noted that when the compressor enters high-temperature or low-temperature protection mode, the frequency reduction protection will decrease the difference between the first detection temperature at the inlet of the cavity and the second detection temperature at the outlet of the cavity. This decrease could be due to either the clothes being dry or the compressor implementing frequency reduction protection. If the latter is the case, and the clothes have already been determined to be dry in previous steps (e.g., when the difference between the temperature difference variation and the upper limit of the temperature difference reaches the preset dryness judgment temperature difference variation), a false judgment will occur. To avoid such false judgments, the compressor needs to be controlled to run at the second frequency for a period of time (i.e., the monitoring duration), and the monitoring duration must be greater than or equal to the third monitoring duration to determine that the clothes are effectively dried, thus improving the accuracy of sensing the degree of dryness.

[0170] Specifically, after deactivating the compressor's high-temperature protection mode or low-temperature protection mode, if the detection duration of the compressor continuing to run at the second frequency is greater than or equal to the third monitoring duration, then the clothes are determined to be dry; conversely, if the detection duration of the compressor continuing to run at the second frequency is less than the third monitoring duration, then the clothes are determined to be not dry.

[0171] For example, the third monitoring duration can be 5 minutes, 10 minutes, 15 minutes or other durations. Taking a third monitoring duration of 5 minutes as an example, if the detection duration is 6 minutes, it can be known that the detection duration is longer than the third monitoring duration, thus determining that the clothes are dry; if the detection duration is 4 minutes, it can be known that the detection duration is shorter than the third monitoring duration, thus determining that the clothes are not dry.

[0172] Specifically, referring to Figure 2, when the temperature difference change value (i.e., dT) is obtained after the decrease of β relative to dT_max, if the compressor enters the high temperature protection mode or low temperature protection mode, the temperature sensing process of the second interval needs to continue. When the high temperature protection mode or low temperature protection mode is released and the detection time is greater than or equal to the third monitoring time, it is determined that the clothes have been dried, and then the second interval of the drying cycle ends and the third interval begins.

[0173] 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 60°C, in order to cool the clothes inside the container cavity. The size of the preset temperature is not limited here.

[0174] Based on the above embodiments and the same inventive concept, this disclosure also provides a control device for a garment processing equipment.
