In addition, in order to facilitate the clear description of the technical solution of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.

[0034] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0035] In the related art, the compressor of heat pump drying equipment will start and stop frequently due to various factors, such as abnormal power outage, high-frequency operation of multiple loads, abnormal ambient temperature detection, filter blockage, etc. The frequent start and stop of the compressor will have a direct impact on the dryness judgment of drying. The dryness judgment stage generally ends the drying by reaching the target dryness judgment number through the accumulated dryness judgment number. If the dryness judgment condition cannot be met for a long time, the drying time will be extended, which seriously affects the user experience.

[0036] In order to solve the above technical problems, this embodiment proposes a method for judging dryness of a heat pump drying device, and the method for judging dryness includes:

[0037] During the dryness judgment process, the number of dryness judgments M executed and the number of compressor shutdowns X during the M dryness judgment processes are accumulated;

[0038] Determine the conversion value Nz of the number of dryness determinations performed according to the number of dryness determinations performed M and the number of compressor shutdowns X;

[0039] Determine the remaining number of dryness determinations Ns according to the preset number of dryness determinations N and the conversion value Nz of the number of dryness determinations already made;

[0040] The dryness determination process ends after the remaining dryness determination times Ns are completed.

[0041] This embodiment determines the conversion value of the number of dry judgments by combining the number of dry judgments and the number of compressor shutdowns, and then determines the remaining number of dry judgments based on the preset number of dry judgments and the conversion value of the number of dry judgments, so as to solve the problem that it is difficult to meet the dry judgment conditions due to frequent start and stop of the compressor, or it is difficult to meet the number of dry judgments even though the dry judgment conditions are met, and to avoid the heat pump drying equipment running for the longest drying time and increasing energy consumption. At the same time, when the compressor frequently stops for protection, the ideal drying effect cannot be achieved, and the clothes may not be dried, consuming more electricity. This embodiment can end the drying in advance by combining the number of dry judgments and the number of compressor shutdowns, which plays a certain energy-saving role.

[0042] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and examples can be combined with each other if there is no conflict.

[0043] First, the execution subject of the dryness determination method of this embodiment is introduced in detail. The dryness determination method of this embodiment is applied to a heat pump drying device, which may have only a drying function or both a drying function and a washing function.

[0044] The clothing treatment device comprises a shell, an outer drum and a clothing treatment drum, wherein the outer drum is arranged in the shell, and the clothing treatment drum is rotatably arranged in the outer drum. An air outlet is arranged on the wall of the outer drum, a door seal is arranged on the drum mouth of the clothing treatment drum, an air inlet is arranged at the door seal, and a plurality of flow holes are arranged on the wall of the clothing treatment drum, and the plurality of flow holes can allow air or water to flow between the outer drum and the clothing treatment drum.

[0045] The clothes processing device further includes an air duct assembly, which is arranged in the space between the housing and the outer drum, preferably arranged above the outer drum. The air duct assembly includes an air inlet duct, an air outlet duct and a fan, the air outlet duct connects the air outlet with the air inlet end of the fan, and the air inlet duct connects the air outlet of the fan with the air inlet.

[0046] The clothing processing device also includes a heat pump system, which includes a compressor, an evaporator, a throttling device and a condenser. The compressor is arranged in the space between the shell and the outer cylinder, preferably at the bottom of the outer cylinder. The evaporator and the condenser are integrated in a two-device box body, and the two-device box body is located between the fan and the air inlet duct, and the condenser is arranged close to the air inlet duct. The compressor, the condenser, the throttling device and the evaporator are connected in sequence to form a refrigerant circulation loop.

[0047] The clothes processing device further comprises a first temperature detection device and a second temperature detection device, wherein the first temperature detection device is used to detect the air inlet temperature of the clothes processing drum, and is preferably arranged at the air inlet. The second temperature detection device is used to detect the air outlet temperature of the clothes processing drum, and is preferably arranged at the air outlet.

[0048] The following is a detailed description of the determination method of this embodiment.

[0049] Combination Figure 1 The present embodiment provides a drying process flow chart of a heat pump drying device, and the drying process flow chart of the ...

[0050] S11. During the dryness determination process, the number of dryness determinations M that have been executed and the number of compressor shutdowns X during the M dryness determination processes are accumulated.

[0051] Specifically, when the heat pump type clothes processing equipment executes the drying program, the drying parameters will be monitored and analyzed in real time to ensure that the clothes processing equipment can complete the drying task efficiently and accurately. These drying parameters mainly include the air inlet temperature, air outlet temperature and / or humidity in the drum. By continuously monitoring these parameters, the equipment can determine whether the clothes have reached the ideal drying state. Specifically, when the drying parameters such as the air inlet temperature, air outlet temperature and / or humidity in the drum reach the preset drying conditions, the drying process is entered.

[0052] In the drying process, the number of drying judgments M executed is accumulated, and the number of drying judgments M is related to the number of times the drying parameters reach the preset drying condition, that is, the number of drying judgments M is accumulated once each time the drying parameters reach the preset drying condition. Exemplarily, in the clothes drying process, by obtaining the inlet and outlet air temperatures of the clothes processing drum, and determining the inlet and outlet air temperature difference according to the inlet and outlet air temperatures, when the inlet and outlet air temperature difference reaches the drying temperature difference, it is determined that the preset drying condition is met. In the subsequent drying process, the number of drying judgments M is accumulated once each time the inlet and outlet air temperature difference reaches the drying temperature difference.

[0053] During the drying process, the clothes processing equipment may start and stop frequently due to abnormal power outages, high-frequency operation of multiple loads, abnormal ambient temperature detection, filter blockage and other problems, and the frequent start and stop of the compressor will cause the drying time to be too long. This embodiment also accumulates the number of compressor shutdowns X, and combines the number of drying judgments M with the number of compressor shutdowns X to determine the remaining number of drying judgments to be executed, so as to solve the problem that it is difficult to meet the drying judgment condition due to frequent start and stop of the compressor, or it is difficult to meet the drying judgment number even if the drying judgment condition is met, so as to avoid the drying time being too long.

[0054] S12, determining a conversion value Nz of the number of dryness determinations performed according to the number of dryness determinations performed M and the number of compressor shutdowns X.

[0055] Specifically, after determining the dryness determination times M and the compressor shutdown times X, the dryness determination times conversion value Nz can be determined according to the dryness determination times M and the compressor shutdown times X. The determination method of the dryness determination times conversion value Nz can be related to the compressor shutdown times, or can be directly a function of the dryness determination times M and the compressor shutdown times X, which is not specifically limited here. After determining the dryness determination times conversion value Nz, in subsequent steps, it can be combined with the preset dryness determination times to determine the remaining dryness determination times Ns.

[0056] S13, determining the remaining number of dryness determination times Ns according to the preset number of dryness determination times N and the converted value Nz of the number of dryness determination times already determined.

[0057] Specifically, after determining the conversion value Nz of the number of dry judgments, a comprehensive judgment can be made by combining the preset number of dry judgments pre-stored in the control device of the clothing processing equipment. The number of dry judgments of the clothing processing equipment can be effectively controlled to automatically end the drying process after the preset number of dry judgments is reached, thereby avoiding excessive drying time and energy waste due to frequent shutdown of the compressor.

[0058] S14, the dryness determination process ends after the remaining dryness determination times Ns are completed.

[0059] After determining the remaining dryness determination times Ns, the dryness determination process can be ended when the number of dryness determinations subsequently executed reaches the remaining dryness determination times Ns.

[0060] In an optional implementation, the method for determining the conversion value Nz of the number of dry-run times varies according to the number of shutdowns of the compressor.

[0061] In one example, the dryness-judged times conversion value Nz is determined based on the executed dryness-judgment times M and the compressor shutdown times X, including: when the compressor shutdown times are greater than the set shutdown times X0, the dryness-judged times conversion value Nz satisfies the formula: Nz=f(M, X), wherein the greater the compressor shutdown times X, the greater the dryness-judged times conversion value Nz; the greater the dryness-judgment times M, the greater the dryness-judgment times conversion value Nz. Exemplarily, the dryness-judged times conversion value Nz satisfies the formula: Nz=f(M, X)=M+(X-X0); wherein: Nz is the dryness-judged times conversion value, M is the executed dryness-judgment times, X is the compressor shutdown times, X0 is the set shutdown times X0, and X0≥0. Preferably, the dryness-judged times conversion value Nz=M+(X-1).

[0062] In another example, the dryness determination times conversion value Nz is determined according to the executed dryness determination times M and the compressor shutdown times X, and further includes: when the compressor shutdown times are less than or equal to the set times X0, the dryness determination times conversion value Nz=M.

[0063] Determining the converted value Nz of the number of dry judgments performed based on the number of dry judgments M and the number of compressor shutdowns X is not limited to the method provided in the above example. In other feasible methods, each compressor shutdown can be converted into one dry judgment, that is, Nz=M+X; or, the number of compressor shutdowns is multiplied by a preset coefficient k1 and converted into one dry judgment, that is, Nz=M+k1×X, 0<k1<1.

[0064] Further preferably, after executing the i-th number of remaining dryness determination times Ns, if the compressor stops, the conversion value of the number of dryness determinations is re-determined to obtain Nz′ and the remaining number of dryness determinations Ns′ is obtained, Ns′=N-Nz′ where Nz′=f((M+i), (X+1)), and then the dryness determination process is terminated after the remaining number of dryness determinations Ns′ is completed. In the dryness determination process of this embodiment, the conversion value of the number of dryness determinations Nz is recalculated each time the compressor stops, thereby ensuring that the conversion value of the number of dryness determinations Nz can be updated in real time according to the number of compressor shutdowns X, further reducing the impact of frequent compressor shutdowns on the dryness determination time.

[0065] In an optional implementation, the remaining number of dryness judgments Ns is determined based on the preset number of dryness judgments N and the conversion value Nz of the number of dryness judgments already made, including: the remaining number of dryness judgments Ns satisfies the formula: Ns=f(N, Nz); wherein: the larger the conversion value Nz of the number of dryness judgments already made is, the smaller the remaining number of dryness judgments Ns is.

[0066] Exemplarily, the remaining dryness judgment times Ns satisfies the formula: Ns=f(N, Nz)=N-Nz; wherein: N is the preset dryness judgment times, Nz is the converted value of the dryness judgment times, and Ns is the remaining dryness judgment times.

[0067] Determining the remaining number of dryness judgments Ns based on the preset number of dryness judgments N and the converted value Nz of the number of dryness judgments that have been made is not limited to the method provided in the above example. In other achievable methods, the converted value Nz of the number of dryness judgments that have been made can also be multiplied by a preset coefficient k2 and then combined with the preset number of dryness judgments N to determine the remaining number of dryness judgments Ns, that is, Ns=N-k2×Nz, 0<k2<1.

[0068] The following is a detailed description of the determination method of this embodiment with reference to a specific example.

[0069] Combination Figure 2 The dryness determination flow chart is as follows, and the dryness determination method includes the following steps:

[0070] S21, the drying process starts, and enters S22;

[0071] S22: The temperature difference between the inlet air temperature and the outlet air temperature reaches the dry temperature difference, and the process goes to S23;

[0072] S23, determine whether the compressor is shut down, if so, execute step S26; if not, execute step S24;

[0073] S24, the accumulated temperature difference between the inlet air temperature and the outlet air temperature reaches the number of times M of the dry temperature difference and the operation is maintained, and the process proceeds to S25;

[0074] S25, judging whether the number M meets the preset number N of drying times, if so, the drying is finished; if not, returning to step S24;

[0075] S26, the accumulated temperature difference between the inlet air temperature and the outlet air temperature reaches the dryness determination temperature difference M times, and then enters S27;

[0076] S27, determine whether the number of compressor shutdowns is ≥ 2, if yes, execute step S28, if no, execute step S211;

[0077] S28, when the number of compressor shutdowns is ≥ 2, the number of dryness determinations M is accumulated +1 each time the compressor is shut down, and the process goes to S29;

[0078] S29, the temperature difference between the inlet air temperature and the outlet air temperature reaches the dry temperature difference or the compressor stops, and the process goes to S210;

[0079] S210, judging whether the drying times meet NM-(X-1) times, if yes, the drying ends, if no, return to S29;

[0080] S211, after the compressor is restarted, the temperature difference between the inlet air temperature and the outlet air temperature reaches the dry temperature difference again, and the process goes to S212;

[0081] S212, determine whether the drying times (NM) are met, if so, the drying is completed; if not, return to step S211.

[0082] In general, the drying judgment method of this embodiment accumulates the number of drying judgments M and optimizes the problem of long drying judgment time caused by frequent start and stop of the compressor. For example, in actual drying operation, the compressor is frequently started and stopped for protection due to abnormal power outages, high-frequency operation of multiple loads, incorrect ambient temperature detection and other factors. The accumulated number of drying judgments M and the number of compressor shutdowns X can be combined to determine the conversion value Nz of the number of drying judgments, and then finally the remaining number of drying judgments Ns to be executed is determined according to the preset number of drying judgments N and the conversion value Nz of the number of drying judgments. Finally, the drying judgment can be completed by executing the remaining number of drying judgments, thereby effectively avoiding the problem of long drying judgment time or even inability to complete the drying judgment due to frequent shutdown of the compressor.
