[0036] 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.

[0037] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0038] According to an embodiment of this application, an embodiment of a drying method for a multi-tube garment processing device is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0039] like Figure 1 As shown, the method includes the following steps:

[0040] S101, in response to the drying signals of the multiple drying cylinders, the drying parameters of the multiple drying cylinders are obtained.

[0041] In one embodiment, when at least two drying drums are simultaneously in a drying state, multiple drying signals for the drying drums are generated. Here, "drying drum in a drying state" means that the drying drum is capable of drying the clothes.

[0042] In one embodiment, each drying cylinder has corresponding drying parameters when it is in the drying state. The drying parameters refer to parameters related to the drying of the drying cylinder, such as drying time and drying temperature. This embodiment does not specifically limit these parameters.

[0043] S102, calculate the air volume parameters in each of the drying cylinders based on the drying parameters of each of the drying cylinders.

[0044] In one embodiment, when the drying cylinder is in the drying state, there is a hot airflow inside. The amount of this hot airflow is the air volume in the drying cylinder, and the parameters related to the air volume in the drying cylinder are the air volume parameters. Specifically, the air volume parameters may include air volume values, air velocity, etc., but this embodiment does not specifically limit these parameters.

[0045] It should be noted that drying parameters reflect the drying progress or degree of drying in the drying drum. For example, the degree of drying of the clothes can be estimated based on the temperature and time in the drying parameters. Therefore, the airflow parameters in the drying drum can be determined based on the drying parameters. The calculated airflow parameters are related to the airflow during the subsequent drying process. In other words, the airflow parameters in the drying drum in this embodiment will change. By obtaining the drying parameters, calculating the changed airflow parameters, and then adjusting the airflow in the drying drum based on the calculated changed airflow parameters, the drying drum can complete the drying process faster and better, improving the drying effect.

[0046] S103, adjust the drying air volume in at least one of the plurality of drying cylinders according to the air volume parameters.

[0047] In one embodiment, after calculating the airflow parameters, the drying airflow in at least one of the multiple drying drums is adjusted, that is, the airflow in at least one drying drum is adjusted to increase or decrease the airflow in the drying drum. Increasing the airflow helps to speed up the drying process; decreasing the airflow helps to slow down the drying process, and at the same time helps to reduce the chance of clothing being damaged due to excessive temperature or excessive airflow.

[0048] Through the above steps, the garment processing equipment has multiple drying drums, and these drums can dry simultaneously, improving drying efficiency. When multiple drying drums are drying simultaneously, multiple drying signals are generated for each drum. At this time, airflow parameters are calculated based on the drying parameters of each drum, and then the drying airflow in at least one drum is adjusted according to the airflow parameters. This ensures that the adjusted drying airflow can dry the clothes in the corresponding drum quickly and thoroughly, improving the drying effect.

[0049] In another embodiment of this application, the drying parameters include motor power.

[0050] The step of calculating the air volume parameters in each of the drying cylinders based on the drying parameters of each of the drying cylinders includes:

[0051] Calculate the air volume parameters in each of the drying cylinders based on the motor power corresponding to each of the drying cylinders.

[0052] In one embodiment, each drying drum is equipped with a motor, which is used to dry the clothes. Therefore, the higher the motor power, the easier and faster the clothes are dried; conversely, the lower the motor power, the more difficult and slower the clothes are dried.

[0053] After obtaining the motor power of each drying cylinder, the air volume parameter can be calculated based on the motor power.

[0054] By following the steps above, the air volume parameters can be calculated using the motor power of the drying drum. Since the motor power can be obtained directly, there is no need to add other sensing or measuring devices to the drying drum, which helps to reduce costs and save space.

[0055] In another embodiment of this application, such as Figure 2 As shown, based on the motor power corresponding to each of the drying cylinders, the air volume parameters in each of the drying cylinders are calculated, including:

[0056] S301, compare the initial power and real-time power of the motor corresponding to each of the drying cylinders to obtain the ratio result of each of the drying cylinders.

[0057] In one embodiment, the motor power corresponding to each drying cylinder includes both the initial motor power and the real-time motor power. When both drying cylinders are in the drying state, the initial motor power and the real-time motor power of the first drying cylinder are compared to obtain the ratio result for the first drying cylinder; the initial motor power and the real-time motor power of the second drying cylinder are compared to obtain the ratio result for the second drying cylinder. It should be noted that in the specific calculation of the ratio result, the real-time motor power is used as the numerator and the initial motor power is used as the denominator for the comparison.

[0058] S302, compare the ratio results of the multiple drying cylinders to obtain the air volume parameter among the multiple drying cylinders.

[0059] In one embodiment, if there are two drying cylinders simultaneously in the drying state, the ratio of the two drying cylinders is compared to obtain the airflow parameter between the two drying cylinders. If there are three or more drying cylinders simultaneously in the drying state, the ratio of one drying cylinder can be used as a reference, and the ratios of the other drying cylinders can be compared with the reference ratio to obtain the airflow parameter between multiple drying cylinders; alternatively, the ratios of all drying cylinders can be compared simultaneously to obtain the airflow parameter between multiple drying cylinders.

[0060] By following the steps above and determining the air volume parameters through a simple calculation process, we can improve calculation efficiency, reduce the probability of calculation errors, and save computing resources.

[0061] In another embodiment of this application, the drying progress of each drying cylinder is determined based on the ratio result corresponding to each drying cylinder.

[0062] In one embodiment, a progress table is preset, which includes a ratio result and the progress, and the ratio result and the progress correspond one-to-one. For example, when the ratio result is 2, the progress is 80%. After knowing the ratio result corresponding to each drying drum, the corresponding value of the progress can be retrieved from the progress table according to the ratio result as the drying progress.

[0063] In another embodiment, since the motor power reflects the drying performance of the drying drum, the drying progress of each drying drum can be determined by combining it with the drying time. For example, when the ratio is 1.5 and the drying time is less than 10 minutes, the drying progress is determined to be 60%. That is, the larger the ratio and the longer the drying time, the greater the drying progress.

[0064] By using the ratio results to determine the drying progress through the above steps, the drying progress can be easily output. Users can then know the remaining drying time based on the drying progress, which helps improve the user experience. Furthermore, the remaining drying time can be calculated based on the drying progress and displayed to inform the user, further enhancing the user experience.

[0065] In another embodiment of this application, adjusting the drying air volume in at least one of the plurality of drying cylinders according to the air volume parameter includes:

[0066] S501, based on the linear function relationship between the air volume of the multiple drying cylinder inlets / outlets, the corresponding air volume parameter is used as the independent variable in the linear function relationship to calculate the opening value of at least one drying cylinder inlet / outlet among the multiple drying cylinders.

[0067] In one embodiment, the larger the opening value of the air inlet / outlet of the drying cylinder, the greater the air inlet / outlet volume of the drying cylinder, and the greater or smaller the air volume inside the drying cylinder, thereby achieving the adjustment of the drying air volume inside the drying cylinder.

[0068] S502, adjust the opening of the air inlet / outlet of the at least one drying cylinder according to the opening value, so as to adjust the drying air volume in at least one of the plurality of drying cylinders.

[0069] In one embodiment, once the opening value is determined, the opening of the corresponding air inlet and / or outlet of the drying cylinder can be adjusted according to the opening value. After the opening changes, the actual air intake / exhaust volume will change.

[0070] By adjusting the opening of the air inlet / outlet through the above steps, the drying air volume inside the drying drum can be changed without adjusting the fan or other components. This method is convenient, quick, and highly accurate, helping to complete the drying process within the specified or calculated time and ensuring the drying effect.

[0071] In another embodiment of this application, the linear function relationship is: K n =a n Q n +b n ;

[0072] Among them, K n a is the opening value of the air inlet / outlet of the nth drying cylinder; n b is the coefficient for the nth drying drum; n Q is a constant term for the nth drying drum; n Let a be the air volume parameter corresponding to the nth drying cylinder; n is a positive integer; a is a non-zero constant; b is a constant.

[0073] In another embodiment of this application, the drying parameters include the temperature inside the drying drum.

[0074] The step of calculating the air volume parameters in each of the drying cylinders based on the drying parameters of each of the drying cylinders includes:

[0075] The air volume parameters of each drying cylinder are obtained by taking the temperature difference between each drying cylinder.

[0076] In one embodiment, if the garment processing equipment has only two drying drums, the temperatures of the two drying drums are compared. In another embodiment, if the garment processing equipment has three or more drying drums, the temperature of one drying drum can be used as a reference, and the temperatures of the other drying drums can be compared to the reference temperature.

[0077] By using the above steps, the air volume parameters can be calculated using the temperature inside the drying drum. Temperature can more directly reflect the degree of drying, thus making it easier to obtain highly accurate air volume parameters.

[0078] In another embodiment of this application, the multiple drying cylinders include an upper drying cylinder and a lower drying cylinder, wherein the upper drying cylinder and the lower drying cylinder share a common air duct, heating device and air supply device.

[0079] There are two drying cylinders, arranged one above the other, sharing a common air duct, heating device, and air supply device. In one embodiment, the air duct is connected to the air outlets and inlets of both the upper and lower drying cylinders, forming a circulating air duct.

[0080] This application also provides a drying device, such as... Figure 3As shown, the drying method described above includes:

[0081] First drying cylinder 1, second drying cylinder 2, air duct, air supply device 3, heating device and air distribution device 4;

[0082] Both the first drying drum 1 and the second drying drum 2 are used for drying clothes;

[0083] The air supply device 3 is used to provide flow power for the airflow in the air duct;

[0084] The heating device is used to heat the airflow within the air duct;

[0085] The air duct includes a main air duct 5, a first air duct 51, a second air duct 52, a third air duct 53, and a fourth air duct 54. The air supply device 3 and the heating device are both located in the main air duct 5. The air outlet of the main air duct 5 is connected to the air inlet of the first air duct 51 and the air inlet of the second air duct 52. The air outlet of the first air duct 51 is connected to the air inlet of the first drying cylinder 1, and the air outlet of the second air duct 52 is connected to the air inlet of the second drying cylinder 2. The air outlet of the first drying cylinder 1 is connected to the air inlet of the third air duct 53, and the air outlet of the second drying cylinder 2 is connected to the air inlet of the fourth air duct 54. The air inlet of the main air duct 5 is connected to the air outlets of the third air duct 53 and the fourth air duct 54.

[0086] The air outlet of the main air duct 5 is provided with the air distribution device 4. The air distribution device 4 is used to selectively open or close the air inlet of the first air duct 51 and the air inlet of the second air duct 52, and / or, the air inlet of the main air duct 5 is provided with the air distribution device 4. The air distribution device 4 is used to selectively open or close the air outlet of the third air duct 53 and the air outlet of the fourth air duct 54.

[0087] Specifically, the air distribution device 4 can be a rotatable switch. Taking the air distribution device 4 installed at the outlet of the main air duct 5 as an example, when the air distribution device 4 is switched to the first position, the air inlet of the first air duct 51 is fully open. That is, the airflow in the main air duct 5 can sequentially pass through the air outlet of the main air duct 5, the air distribution device 4, the air inlet of the first air duct 51, the air outlet of the first air duct 51, and the air inlet of the first drying drum 1, and enter the first drying drum 1 to dry the clothes. At the same time, the air inlet of the second air duct 52 is fully open. That is, the airflow in the main air duct 5 can sequentially pass through the air outlet of the main air duct 5, the air distribution device 4, the air inlet of the second air duct 52, the air outlet of the second air duct 52, and the air inlet of the second drying drum 2, and enter the second drying drum 2 to dry the clothes. When the air distribution device 4 is switched to the second position, the air inlet of the first air duct 51 is completely blocked, and the air inlet of the second air duct 52 is completely blocked, preventing the airflow in the main air duct 5 from entering the first drying cylinder 1 and the second drying cylinder 2. When the air distribution device 4 is switched to the third position, the air inlet of the first air duct 51 is partially blocked, and the air inlet of the second air duct 52 is partially blocked. The partial blocking can be one-tenth or half of the air duct; this embodiment does not specify a particular limit. Furthermore, the air distribution device 4 can also be in the fourth position where the air inlet of the first air duct 51 is completely blocked, but the air inlet of the second air duct 52 is fully open; and in the fifth position where the air inlet of the second air duct 52 is completely blocked, but the air inlet of the first air duct 51 is fully open; this embodiment does not specify a particular limit.
