Description

Technical Field

[0001] This application relates to the field of drying equipment technology, and more specifically, to a drying method, control device, and clothing processing equipment with drying function for clothing processing equipment. Background Technology

[0002] Current drying equipment requires a cooling period after the drying process to lower the drum temperature to a level that will not burn the user. However, the duration of this cooling process is not controllable by the user, who cannot pre-set the cooling time according to their needs, thus failing to meet the user's need to quickly remove clothes after drying. Summary of the Invention

[0003] This application provides a drying method, control device, and clothing processing equipment with drying function for clothing processing, so as to at least solve the technical problem that users cannot pre-determine the cooling time after drying according to their needs.

[0004] According to a first aspect of the embodiments of this application, a drying method for a garment processing device is provided. The garment processing device includes a garment processing drum and a drying system. The drying system includes an air duct, a fan, and a heat pump assembly. The air duct connects the air inlet and air outlet of the garment processing drum. The fan is disposed in the air duct. The heat pump assembly includes an evaporator and a condenser. Both the evaporator and the condenser are disposed within the air duct, and the condenser is located downstream of the evaporator in the airflow direction. The drying method includes:

[0005] During the drying and cooling phase of the clothes drying process, the temperature of the condenser tube and the target location temperature of the clothes handling drum are obtained.

[0006] The fan speed is controlled according to the condenser tube temperature and the target location temperature to cool the target location temperature to the target temperature within the target cooling time.

[0007] According to the drying method of this application, the fan speed is adjusted according to the temperature of the condenser and the target position temperature of the clothes handling drum during the drying and cooling stage. This ensures that the temperature of the target position of the clothes handling drum is cooled to a temperature that will not burn the user within the target cooling time, thus meeting the user's personalized needs. This avoids both excessive fan speed, which increases cooling energy consumption, and insufficient fan speed, which leads to excessively long cooling time and fails to meet the user's need to take out the clothes in a hurry after drying.

[0008] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the target temperature of the clothing processing drum is the outlet temperature and / or the internal temperature of the clothing processing drum.

[0012] The rotational speed of the fan is corrected based on ΔT1 and ΔT2.

[0013] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the step of correcting the fan speed based on ΔT1 and ΔT2 includes:

[0014] If ΔT1 > ΔT2, and ΔT2 > set temperature difference, then the first speed is reduced based on the initial speed; if ΔT2 < set temperature difference, then the second speed is increased based on the initial speed; if ΔT2 = set temperature difference, then the initial speed is maintained.

[0015] If ΔT1≤ΔT2, and ΔT2>set temperature difference, then the third speed is reduced based on the initial speed; if ΔT2<set temperature difference, then the fourth speed is increased based on the initial speed; if ΔT2=set temperature difference, then the initial speed is maintained.

[0016] The set temperature difference is related to the target cooling time, and the first rotation speed is less than the third rotation speed, and the second rotation speed is less than the fourth rotation speed.

[0017] In conjunction with the first aspect, in an optional implementation of this application embodiment, determining the initial rotational speed of the fan during the drying and cooling stage based on the target cooling duration includes:

[0018] The initial speed of the fan during the cooling phase is determined based on the preset correspondence between the target cooling time and the initial speed, and the shorter the target cooling time, the higher the initial speed.

[0019] The fan is controlled to operate at the determined initial speed.

[0020] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the drying method further includes:

[0021] During the cooling phase, the rotation rhythm of the clothing processing drum is also determined according to the fan speed.

[0022] The garment processing drum is controlled to rotate at the aforementioned rotation rhythm.

[0023] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the fan speed and the rotation rhythm of the clothing processing drum have a preset correspondence, and the higher the fan speed, the greater the ratio of the rotation time to the stop time of the rotation rhythm.

When the one or more processors execute the program instructions, the one or more processors are used to implement the drying method proposed in the first aspect of the present application.

[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0034] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply that they are different.

[0035] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0036] Because current drying equipment cannot meet users' needs by allowing them to pre-customize the cooling time after drying, it fails to satisfy personalized user requirements. Therefore, this embodiment proposes a drying method for clothing processing equipment, the drying method including:

[0037] During the drying and cooling phase of the clothes drying process, the temperature of the condenser tube and the target location temperature of the clothes handling drum are obtained.

[0038] The fan speed is controlled based on the condenser tube temperature and the target location temperature to cool the target location temperature to the target temperature within the target cooling time.

[0039] This embodiment adjusts the fan speed based on the condenser temperature and the target temperature of the clothes handling drum during the drying and cooling stage. This ensures that the temperature of the target location of the clothes handling drum is cooled to a level that will not burn the user within the target cooling time, thus meeting the user's personalized needs. It avoids both excessively high fan speeds that increase cooling energy consumption and excessively slow fan speeds that lead to excessively long cooling times, which would not meet the user's need to quickly remove the clothes after drying.

[0040] The drying method of this embodiment will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and examples can be combined with each other.

[0041] First, the main body implementing the drying method of this embodiment will be described in detail.

[0042] The drying method of this embodiment is applied to a garment processing device, which may have only a drying function or may have both a washing function and a drying function.

[0043] In one example, the garment processing device includes a housing and a garment processing cylinder, wherein the garment processing cylinder is disposed within the housing. The cylinder wall of the garment processing cylinder has an air outlet, the cylinder opening of the garment processing cylinder has a door seal, and the door seal has an air inlet.

[0044] The garment processing equipment also includes an air duct assembly, which is disposed in the space between the housing and the garment processing drum, preferably above the garment processing drum. The air duct assembly includes an inlet air duct, an outlet air duct, and a fan. The outlet air duct connects the outlet to the inlet of the fan, and the inlet air duct connects the outlet of the fan to the inlet.

[0045] The garment processing equipment also includes a heat pump assembly for dehumidifying the airflow within the air duct assembly. The heat pump assembly includes a compressor, evaporator, throttling device, and condenser. The compressor is located in the space between the housing and the outer cylinder, preferably at the bottom of the outer cylinder. The evaporator and condenser are integrated into a two-electrode housing located between the fan and the air inlet duct, with the condenser positioned close to the air inlet duct. The compressor, condenser, throttling device, and evaporator are connected sequentially to form a refrigerant circulation loop.

[0046] During the clothes drying process, the hot, humid airflow entering the air duct assembly is blown towards the evaporator by the fan. After absorbing heat in the evaporator, it forms dry, cold air. This dry, cold air then flows through the condenser and is heated to form a high-temperature airflow. Finally, this high-temperature airflow enters the clothes processing drum to dry the clothes inside. When the heat pump assembly is on, the compressor is in the start-up state, allowing the refrigerant to circulate in the refrigerant circulation path.

[0047] The garment processing equipment also includes a first temperature detection device and a second temperature detection device. The first temperature detection device is used to detect the temperature of the condenser tube, and the second temperature detection device is used to detect the temperature at a target location in the garment processing drum, such as the inside of the garment processing drum or the air outlet of the garment processing drum.

[0048] Next, the drying method of this embodiment will be described in detail with reference to the accompanying drawings.

[0049] This embodiment proposes a drying method for a garment processing device, referring to... Figure 1 The drying process flow chart shows the following steps:

[0050] S11. During the drying and cooling stage of the clothes drying process, obtain the temperature of the condenser tube and the temperature at the target location of the clothes handling drum.

[0051] In this embodiment, before drying, the user can select or input the target cooling duration for the drying and cooling stage through the control terminal of the clothing processing equipment. During the drying process, the heat pump component is started first, that is, the compressor is started and the fan is started. The airflow circulates between the clothing processing drum and the air duct. The evaporator is used to cool and dehumidify the humid airflow entering the air duct, and the condenser is used to heat the airflow processed by the evaporator. The heated airflow enters the clothing processing drum, causing the temperature inside the clothing processing drum to rise.

[0052] The drying process of the garment processing equipment includes a drying and heating stage and a drying and dehumidification stage. In the initial stage of drying, the temperature inside the garment processing drum decreases, requiring the introduction of hot air to raise the temperature. Once the conditions for ending the drying and heating stage are met, the drying and dehumidification stage begins. For example, the drying and heating stage is considered complete when the inlet air temperature of the garment processing drum reaches a first set temperature.

[0053] During the drying and dehumidification stage, as the temperature inside the drum rises, the humidity inside the clothes processing drum gradually increases. At this time, it is necessary to continuously supply dry and hot airflow into the drum to dehumidify the clothes. When the end conditions of the drying and dehumidification stage are reached, it is determined whether the drying condition has been met. For example, when the outlet air temperature of the clothes processing drum reaches the second set temperature, it is determined that the end condition of reaching the drying and dehumidification temperature has been met.

[0054] Once the drying criteria are met, it indicates that the clothes inside the drum are dry, and the drying and cooling stage begins. For example, the drying criteria are determined by the number of times the temperature difference between the inlet and outlet air temperatures of the clothes processing drum reaches a set temperature difference.

[0055] After entering the cooling stage, the compressor is stopped to prevent the clothes handling drum from continuing to heat up. At this time, the fan needs to be kept running to deliver cold air into the clothes handling drum to cool it down. Since the condenser still has residual heat after the compressor stops, during the cooling process, the fan airflow blowing over the condenser will carry this residual heat into the clothes handling drum, affecting its cooling speed. Therefore, this embodiment monitors the condenser tube temperature and the target temperature of the clothes handling drum to control the fan speed in subsequent steps.

[0056] The target temperature of the garment processing drum is one of the outlet temperature and / or the internal temperature of the garment processing drum, preferably the internal temperature of the garment processing drum, which can more accurately reflect the internal temperature of the garment processing drum.

[0057] S12. Control the fan speed according to the condenser tube temperature and the target location temperature to cool the target location temperature to the target temperature within the target cooling time.

[0058] In this embodiment, after determining the condenser tube temperature and the target location temperature, the fan speed is adjusted based on the user-selected target cooling time combined with the condenser tube temperature and the target location temperature. This ensures that the cooling time of the clothes handling drum at the adjusted fan speed matches the user's target cooling time, thus meeting the user's personalized needs. Specifically, if the user urgently needs to remove the dried clothes, the cooling can be achieved quickly; otherwise, if the user is not in a hurry to remove the dried clothes but has energy-saving requirements, the cooling can be achieved slowly.

[0059] It should be noted that the clothing processing equipment in this embodiment has a minimum cooling time, meaning that the target drying time selected or entered by the user must be greater than or equal to the minimum cooling time. When the user selects the minimum cooling time, the fan generally rotates at its maximum speed. The minimum cooling time is, for example, 5 to 10 minutes.

[0060] In one alternative implementation, refer to Figure 2 The drying process flow chart, which controls the fan speed based on the condenser tube temperature and the target location temperature, includes the following steps:

[0061] S21. Control the initial speed of the fan during the drying and cooling stage according to the target cooling time;

[0062] S22. Determine the first temperature change value ΔT1 of the condenser tube temperature per unit time, and the second temperature change value ΔT2 of the target location temperature per unit time.

[0063] S23. Correct the fan speed based on ΔT1 and ΔT2.

[0064] In this embodiment, after entering the drying and cooling stage, the initial speed of the fan in the cooling stage is first determined. The initial speed is related to the target cooling time. Generally, the shorter the target cooling time, the higher the initial speed.

[0065] In a preferred embodiment, controlling the initial speed of the fan during the drying and cooling stage according to the target cooling duration includes: determining the initial speed of the fan during the cooling stage corresponding to the current target speed based on a preset correspondence between the target cooling duration and the initial speed. After determining the target cooling duration, the corresponding initial speed of the fan can be determined by looking up a table. After entering the cooling stage, the fan is controlled to rotate at the determined initial speed.

[0066] During the drying and cooling stage, the condenser tube temperature and the target location temperature are continuously monitored. The first temperature change ΔT1 of the condenser tube temperature per unit time and the second temperature change ΔT2 of the target location temperature per unit time are calculated. The first temperature change ΔT1 reflects the cooling rate of the condenser, and the second temperature change ΔT2 reflects the cooling speed of the garment processing drum. The first temperature change ΔT1 and the second temperature change ΔT2 are then compared, and the second temperature change ΔT2 is compared with the set temperature difference to adjust the fan speed. The unit time is, for example, 10 seconds, 20 seconds, or 30 seconds. The set temperature difference is related to the target cooling duration; the longer the target cooling duration, the smaller the set temperature difference. The set temperature difference corresponding to the current target cooling duration can be determined by pre-establishing the correspondence between the target cooling duration and the set temperature difference.

[0067] For example, the fan speed is corrected based on ΔT1 and ΔT2, including: if ΔT1 > ΔT2, it means that the cooling rate of the condenser is faster than that of the clothes handling drum, and the condenser loses heat faster. If ΔT2 > the set temperature difference, it means that the cooling rate inside the drum is too fast. If the fan rotates at the initial speed, the cooling time will be shorter than the target cooling time, but the cooling energy consumption will increase. Therefore, the first speed needs to be reduced based on the initial speed. If ΔT2 < the set temperature difference, it means that the cooling rate inside the drum is too slow. If the fan rotates at the initial speed, the cooling time will be longer than the target cooling time, which cannot meet the user's needs. Therefore, the second speed needs to be increased based on the initial speed. If ΔT2 = the set temperature difference, it means that the cooling rate inside the drum is more appropriate. If the fan rotates at the initial speed, the cooling time will be equivalent to the target cooling time. Therefore, the initial speed is maintained.

[0068] If ΔT1 < ΔT2, it indicates that the cooling rate of the condenser is slower than that of the clothes-washing drum, and the condenser dissipates heat more slowly. If ΔT2 > the set temperature difference, it indicates that the cooling rate inside the drum is too fast. If the fan rotates at the initial speed, the cooling time will be shorter than the target cooling time, but the cooling energy consumption will increase. Therefore, the third speed needs to be reduced based on the initial speed. If ΔT2 < the set temperature difference, it indicates that the cooling rate inside the drum is too slow. If the fan rotates at the initial speed, the cooling time will be longer than the target cooling time, which cannot meet the user's needs. Therefore, the fourth speed needs to be increased based on the initial speed. If ΔT2 = the set temperature difference, it indicates that the cooling rate inside the drum is appropriate. If the fan rotates at the initial speed, the cooling time will be equivalent to the target cooling time. Therefore, the initial speed should be maintained.

[0069] Since ΔT1 < ΔT2, the condenser loses heat more slowly. Therefore, the third speed is set to be greater than the first speed, and the fourth speed is set to be less than the second speed, in order to avoid the condenser taking too long to dissipate heat and thus affecting the cooling rate inside the cylinder.

[0070] In one alternative implementation, refer to Figure 3 The drying process flow chart shows that the drying method also includes the following steps:

[0071] S31. During the cooling phase, the rotation rhythm of the clothes handling drum is also determined according to the fan speed.

[0072] S32. Control the clothes processing drum to rotate at a certain rhythm.

[0073] In this embodiment, considering the slow cooling rate inside the drum, the fan speed cannot be increased indefinitely. Therefore, even when the fan speed reaches its maximum, the cooling rate inside the drum may still not reach the target temperature within the target cooling time. In this case, during the drying and cooling stage, the rotation of the clothes handling drum can also be controlled. By combining the rotation of the clothes handling drum with the fan speed, the cooling rate inside the drum can be better matched with the target cooling time.

[0074] Specifically, during the cooling phase, the cooling rhythm of the garment processing drum is determined based on the fan speed. There is a pre-defined correspondence between the fan speed and the drum's rotation rhythm; the higher the fan speed, the greater the ratio of rotation time to stop time. This is because a higher fan speed means that to achieve the target temperature within the drum within the target cooling time, the cooling rate needs to be accelerated. This can be achieved by extending the drum's rotation time and shortening its stop time. Conversely, a lower fan speed means that to achieve the target temperature within the drum within the target cooling time, the cooling rate needs to be slowed down. This can also be achieved by shortening the drum's rotation time and extending its stop time.

[0075] In a preferred embodiment, when the drying process ends and the cooling and drying phase begins, the display screen of the garment processing equipment also displays the target cooling time set by the user, and the target cooling time is updated in the form of a countdown as the cooling phase progresses, so that the user can clearly understand the remaining cooling time.

[0076] In summary, this embodiment uses the user-defined target cooling time as the control guide and continuously monitors the condenser tube temperature and the target position temperature of the clothes handling drum to regulate the fan speed during the drying and cooling stage. This ensures that the target position temperature of the clothes handling drum reaches a temperature that will not burn the user when the target cooling time is reached. This satisfies both the user's need to quickly remove the dried items after drying and the user's desire to reduce cooling energy consumption, thus improving the user experience.

Parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0078] It should be noted that, Figure 1 Step S12 in the illustrated embodiment can be Figure 2 The steps S21 to S31 in the illustrated embodiment are replaced; Figure 1 Step S12 in the illustrated embodiment can be combined with... Figure 3 The combination of steps S31 to S32 in the illustrated embodiment is intended to cool the target location temperature to the target temperature within the target cooling time.

[0088] S409. Determine whether ΔT1>ΔT2 is satisfied. If the result is yes, proceed to S410. If the result is no, proceed to S411.

[0089] S4010. If ΔT2 > set temperature difference, then reduce the first speed based on the initial speed; if ΔT2 = set temperature difference, then maintain the initial speed; if ΔT2 < set temperature difference, then increase the second speed based on the initial speed.

[0090] S411. If ΔT2 > set temperature difference, then reduce the third speed based on the initial speed; if ΔT2 = set temperature difference, then maintain the initial speed; if ΔT2 < set temperature difference, then increase the fourth speed based on the initial speed.

Determine the first temperature change value ΔT1 of the condenser tube temperature per unit time, and the second temperature change value ΔT2 of the target location temperature per unit time; The rotational speed of the fan is corrected based on ΔT1 and ΔT2; The step of correcting the fan speed based on ΔT1 and ΔT2 includes: If ΔT1 > ΔT2, and ΔT2 > set temperature difference, then the first speed is reduced based on the initial speed; if ΔT2 < set temperature difference, then the second speed is increased based on the initial speed; if ΔT2 = set temperature difference, then the initial speed is maintained. If ΔT1 < ΔT2, and ΔT2 > the set temperature difference, then the third speed is reduced based on the initial speed; if ΔT2 < the set temperature difference, then the fourth speed is increased based on the initial speed; if ΔT2 = the set temperature difference, then the initial speed is maintained. The set temperature difference is related to the target cooling time, and the first rotation speed is less than the third rotation speed, and the second rotation speed is less than the fourth rotation speed.
