Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a control method for clothing processing equipment and clothing processing equipment. Background Technology

[0002] Condensation drying is a common drying technology widely used in washer-dryer combos and other garment drying equipment. The principle of condensation drying is as follows: a heating device heats the air to create hot air, which is then blown into the clothes inside the drum by a fan. The hot air exiting the drum becomes cool, humidified air, which then flows through a condenser for dehumidification. The condenser liquefies the water vapor in the cool, humid air and discharges it through a drain pipe. The dehumidified air is then reheated by the heating device and continues to move into the drum. This cycle repeats until the clothes are completely dried.

[0003] In existing technologies, clothing processing equipment with condenser drying function maintains a constant drying air velocity and drying time during the drying process. This can lead to technical problems such as incomplete drying when there are many clothes to be dried due to the relatively low drying air velocity and relatively short drying time; or energy waste when there are few clothes to be dried due to the relatively high drying air velocity and relatively long drying time.

[0004] Therefore, there is an urgent need for a control method for clothing processing equipment and clothing processing equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a control method for clothing processing equipment and improve clothing processing efficiency. During the drying process, the speed and working time of the drying fan can be adaptively adjusted according to the specific conditions of the clothes to be dried.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A control method for garment processing equipment is provided for controlling the drying process of the garment processing equipment. The garment processing equipment includes a drying fan, an air duct, and a condenser. The drying fan and the condenser are both disposed within the air duct. The control method for the garment processing equipment includes the following steps:

[0008] S1. Set the initial speed of the drying fan and obtain the initial humidity difference between the return air inlet and the air inlet of the air duct;

[0009] S2. Control the speed of the drying fan to increase by a set value, and control the drying fan to operate at the current speed for a first duration, then obtain the current humidity difference between the return air inlet and the air inlet;

[0010] S3. Adjust the speed and working time of the drying fan according to the current humidity difference until the current humidity difference is less than the humidity difference threshold, and then control the drying program to end.

[0011] Optionally, in step S3, adjusting the speed and operating time of the drying fan according to the current humidity difference includes the following steps:

[0012] S31. Determine whether the current humidity difference is greater than the previous humidity difference, wherein the previous humidity difference is the humidity difference obtained before the current humidity difference;

[0013] S32. Adjust the speed and working time of the drying fan according to the judgment result.

[0014] Optionally, step S32 includes:

[0015] If the determination result is that the current humidity difference is greater than the previous humidity difference, then determine whether the current speed of the drying fan is less than the maximum speed of the drying fan; if the current speed of the drying fan is less than the maximum speed of the drying fan, then return to step S2; if the current speed of the drying fan is not less than the maximum speed of the drying fan, then control the drying fan to maintain the current speed unchanged and continue to rotate for a second duration.

[0016] If the determination result is that the current humidity difference is not greater than the previous humidity difference, then the drying fan is controlled to maintain the current speed unchanged and continue to rotate for a second duration.

[0017] Optionally, step S3 further includes;

[0018] S33. At a third time interval, obtain the current humidity difference between the return air vent and the air inlet;

[0019] S34. Determine whether the current humidity difference is less than the humidity difference threshold;

[0020] If so, the drying process will end.

[0021] If not, return to step S33.

[0022] Optionally, in step S34, when the current humidity difference is less than the humidity difference threshold, the drying fan is controlled to continue working for a fourth duration, and then the drying program is controlled to end.

[0023] Optionally, a first humidity sensor is provided at the return air vent, and a second humidity sensor is provided at the air inlet. The humidity difference is the value obtained by subtracting the humidity value collected by the second humidity sensor from the humidity value collected by the first humidity sensor.

[0024] A garment processing device, comprising a drying fan, an air duct, and a condenser, wherein the drying fan and the condenser are both disposed within the air duct, and the drying process of the garment processing device is controlled by the aforementioned garment processing device control method.

[0025] Optionally, the condenser is a semiconductor condenser.

[0026] Optionally, the condenser includes:

[0027] A condenser box is disposed in the air duct, and the condenser box has openings at both ends, and both openings are connected to the air duct.

[0028] A semiconductor refrigeration element is disposed in the condenser box;

[0029] A condenser blade is disposed on one side of the semiconductor refrigeration chip and located inside the condenser box;

[0030] Heat dissipation blades are disposed on the other side of the semiconductor cooling chip and located outside the condenser box.

[0031] Optionally, the condenser further includes a cooling fan, which is located outside the condenser box and can blow air toward the cooling blades.

[0032] The beneficial effects of this invention are:

[0033] The clothing processing equipment control method proposed in this invention sets the initial speed of the drying fan and obtains the initial humidity difference between the return air inlet and the air inlet of the air duct in the initial stage of the drying process. Then, the speed of the drying fan is increased by the set value, and the drying fan operates at the current speed for a first duration. Subsequently, the current humidity difference between the return air inlet and the air inlet is obtained. Next, based on the current humidity difference, the speed and operating time of the drying fan are adjusted until the current humidity difference is less than a humidity difference threshold, at which point the drying process ends. In this way, the speed and operating time of the drying fan can be adaptively adjusted according to the specific conditions of the clothes to be dried during the drying process. This avoids the technical problem of incomplete drying due to relatively low drying speed and relatively short drying time when there are many clothes to be dried, and also avoids the technical problem of energy waste due to relatively high drying speed and relatively long drying time when there are few clothes to be dried.

[0034] The garment processing equipment proposed in this invention uses the aforementioned garment processing equipment control method to control the drying process. During the drying process, the rotation speed and operating time of the drying fan can be adaptively adjusted according to the specific conditions of the garments to be dried. This avoids the technical problem of incomplete drying due to relatively low drying air speed and relatively short drying time when there are many garments to be dried; and also avoids the technical problem of energy waste due to relatively high drying air speed and relatively long drying time when there are few garments to be dried.

[0052] Example 1

[0053] This embodiment provides a control method for a garment processing device, used to control the drying program of the garment processing device.

[0054] Specifically, see Figure 1 and Figure 2The garment processing equipment includes a drying fan 1, an air duct 2, and a condenser 3. Both the drying fan 1 and the condenser 3 are located inside the air duct 2.

[0055] Specifically, the garment processing equipment also includes a housing (not shown in the figure), within which an outer cylinder 4 and an inner cylinder 5 are coaxially arranged, with a gap between them, which forms part of the air duct 2. In addition to the gap between the outer cylinder 4 and the inner cylinder 5, the air duct 2 also includes an outer cavity 23. The two ends of the outer cavity 23 are the air inlet 22 and the air return outlet 21 of the air duct 2, respectively. The outer cavity 23 is located on the outer periphery of the gap between the outer cylinder 4 and the inner cylinder 5 and connects between the air inlet 22 and the air return outlet 21 of the air duct 2. The drying fan 1 and the condenser 3 are both located within the outer cavity 23 of the air duct 2, with the drying fan 1 positioned near the air inlet 22 and the condenser 3 positioned near the air return outlet 21.

[0056] When the garment processing equipment executes the drying program, the clothes to be dried are located inside the inner drum 5. The inner drum 5 rotates around its own axis under the drive of the inner drum drive motor, thereby causing the clothes to tumble. The drying fan 1 blows out high-temperature, low-humidity air, which enters the gap between the outer drum 4 and the inner drum 5 through the air inlet 22, and then enters the inner drum 5 to dry the clothes. Subsequently, the high-temperature, low-humidity air becomes low-temperature, high-humidity air. The low-temperature, high-humidity air flows from the return air inlet 21 into the outer cavity 23. When it passes through the condenser 3, the condenser 3 condenses and dehumidifies the low-temperature, high-humidity air, which then becomes low-temperature, low-humidity air. The low-temperature, low-humidity air flows to the drying fan 1 and is heated again by the drying fan to form high-temperature, low-humidity air. This cycle repeats until the clothes to be dried in the inner drum 5 are completely dried.

[0057] To avoid the clothing processing equipment maintaining a constant drying speed and drying time during the drying process, thus failing to adapt to the specific conditions of the clothes to be dried, this embodiment refers to... Figure 3 The control method for garment processing equipment includes the following steps:

[0058] S1. Set the initial speed of the drying fan 1 and obtain the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2;

[0059] S2. Increase the speed of the drying fan 1 by the set value, and control the drying fan 1 to work at the current speed for a first duration, and then obtain the current humidity difference between the return air vent 21 and the air inlet 22;

[0060] S3. Adjust the speed and working time of the drying fan 1 according to the current humidity difference until the current humidity difference is less than the humidity difference threshold, and then control the drying program to end.

[0061] Optionally, in step S1, the initial speed of the drying fan 1 is set as needed, preferably not exceeding one-quarter of the maximum speed of the drying fan 1. For example, taking a drying fan 1 with a maximum speed of 1000 rpm as an example, its initial speed does not exceed 250 rpm.

[0062] Optionally, in step S2, the setting value is 50 rpm to 200 rpm. For example, the setting value can be selected as 50 rpm, 100 rpm, 150 rpm or 200 rpm.

[0063] Optionally, the first duration is 5 min to 20 min. For example, the first duration can be selected as 5 min, 10 min, 15 min, or 20 min.

[0064] It is understandable that in step S3, the condensing efficiency of condenser 3 (that is, the drying efficiency of the clothes to be dried) can be determined based on the specific situation of the current humidity difference.

[0065] The clothing processing equipment control method provided in this embodiment sets the initial rotation speed of the drying fan 1 in the initial stage of the drying process and obtains the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2. Then, the rotation speed of the drying fan 1 is increased by the set value, and the drying fan 1 operates at the current rotation speed for a first duration. Subsequently, the current humidity difference between the return air inlet 21 and the air inlet 22 is obtained. Next, based on the current humidity difference, the rotation speed and operating time of the drying fan 1 are adjusted until the current humidity difference is less than a humidity difference threshold, at which point the drying process ends. In this way, during the drying process, the rotation speed and operating time of the drying fan 1 can be adaptively adjusted according to the specific conditions of the clothes to be dried, avoiding the technical problem of incomplete drying due to relatively low drying speed and relatively short drying time when there are many clothes to be dried; and also avoiding the technical problem of energy waste due to relatively high drying speed and relatively long drying time when there are few clothes to be dried.

[0066] Furthermore, a first humidity sensor 211 is installed at the return air vent 21, and a second humidity sensor 221 is installed at the air inlet 22. The humidity difference is the value obtained by subtracting the humidity value collected by the second humidity sensor 221 from the humidity value collected by the first humidity sensor 211.

[0067] Example 2

[0068] This embodiment provides a control method for a garment processing device, used to control the drying program of the garment processing device.

[0069] Specifically, see Figure 1 and Figure 2The garment processing equipment includes a drying fan 1, an air duct 2, and a condenser 3. Both the drying fan 1 and the condenser 3 are located inside the air duct 2.

[0070] Specifically, the garment processing equipment also includes a housing (not shown in the figure), within which an outer cylinder 4 and an inner cylinder 5 are coaxially arranged, with a gap between them, which forms part of the air duct 2. In addition to the gap between the outer cylinder 4 and the inner cylinder 5, the air duct 2 also includes an outer cavity 23. The two ends of the outer cavity 23 are the air inlet 22 and the air return outlet 21 of the air duct 2, respectively. The outer cavity 23 is located on the outer periphery of the gap between the outer cylinder 4 and the inner cylinder 5 and connects between the air inlet 22 and the air return outlet 21 of the air duct 2. The drying fan 1 and the condenser 3 are both located within the outer cavity 23 of the air duct 2, with the drying fan 1 positioned near the air inlet 22 and the condenser 3 positioned near the air return outlet 21.

[0071] When the garment processing equipment executes the drying program, the clothes to be dried are located inside the inner drum 5. The inner drum 5 rotates around its own axis under the drive of the inner drum drive motor, thereby causing the clothes to tumble. The drying fan 1 blows out high-temperature, low-humidity air, which enters the gap between the outer drum 4 and the inner drum 5 through the air inlet 22, and then enters the inner drum 5 to dry the clothes. Subsequently, the high-temperature, low-humidity air becomes low-temperature, high-humidity air. The low-temperature, high-humidity air flows from the return air inlet 21 into the outer cavity 23. When it passes through the condenser 3, the condenser 3 condenses and dehumidifies the low-temperature, high-humidity air, which then becomes low-temperature, low-humidity air. The low-temperature, low-humidity air flows to the drying fan 1 and is heated again by the drying fan to form high-temperature, low-humidity air. This cycle repeats until the clothes to be dried in the inner drum 5 are completely dried.

[0072] To avoid the clothing processing equipment maintaining a constant drying speed and drying time during the drying process, thus failing to adapt to the specific conditions of the clothes to be dried, this embodiment refers to... Figure 3 The control method for garment processing equipment includes the following steps:

[0073] S1. Set the initial speed of the drying fan 1 and obtain the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2;

[0074] S2. Increase the speed of the drying fan 1 by the set value, and control the drying fan 1 to work at the current speed for a first duration, and then obtain the current humidity difference between the return air vent 21 and the air inlet 22;

[0075] S3. Adjust the speed and working time of the drying fan 1 according to the current humidity difference until the current humidity difference is less than the humidity difference threshold, and then control the drying program to end.

[0076] Optionally, in step S1, the initial speed of the drying fan 1 is set as needed, preferably not exceeding one-quarter of the maximum speed of the drying fan 1. For example, taking a drying fan 1 with a maximum speed of 1000 rpm as an example, its initial speed does not exceed 250 rpm.

[0077] Optionally, in step S2, the setting value is 50 rpm to 200 rpm. For example, the setting value can be selected as 50 rpm, 100 rpm, 150 rpm or 200 rpm.

[0078] Optionally, the first duration is 5 min to 20 min. For example, the first duration can be selected as 5 min, 10 min, 15 min, or 20 min.

[0079] The clothing processing equipment control method provided in this embodiment sets the initial rotation speed of the drying fan 1 in the initial stage of the drying process and obtains the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2. Then, the rotation speed of the drying fan 1 is increased by the set value, and the drying fan 1 operates at the current rotation speed for a first duration. Subsequently, the current humidity difference between the return air inlet 21 and the air inlet 22 is obtained. Next, based on the current humidity difference, the rotation speed and operating time of the drying fan 1 are adjusted until the current humidity difference is less than a humidity difference threshold, at which point the drying process ends. In this way, during the drying process, the rotation speed and operating time of the drying fan 1 can be adaptively adjusted according to the specific conditions of the clothes to be dried, avoiding the technical problem of incomplete drying due to relatively low drying speed and relatively short drying time when there are many clothes to be dried; and also avoiding the technical problem of energy waste due to relatively high drying speed and relatively long drying time when there are few clothes to be dried.

[0080] Furthermore, a first humidity sensor 211 is installed at the return air vent 21, and a second humidity sensor 221 is installed at the air inlet 22. The humidity difference is the value obtained by subtracting the humidity value collected by the second humidity sensor 221 from the humidity value collected by the first humidity sensor 211.

[0081] Specifically, see Figure 4 In this embodiment, step S3, adjusting the speed and operating time of the drying fan 1 according to the current humidity difference, includes the following steps:

[0082] S31. Determine whether the current humidity difference is greater than the previous humidity difference. The previous humidity difference is the humidity difference obtained before the current humidity difference.

[0083] S32. Adjust the speed and working time of the drying fan 1 according to the judgment result.

[0084] It should be noted that in step S31, the current humidity difference is the latest humidity difference updated in real time; the previous humidity difference is the humidity difference before the latest humidity difference.

[0085] For example, in this embodiment, when executing the clothing processing equipment control method, the following steps are performed:

[0086] S1. Set the initial speed of the drying fan 1 and obtain the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2;

[0087] S2. Increase the speed of the drying fan 1 by the set value, and control the drying fan 1 to work at the current speed for a first duration, and then obtain the current humidity difference between the return air vent 21 and the air inlet 22;

[0088] S31. Determine whether the current humidity difference is greater than the previous humidity difference. The previous humidity difference is the initial humidity difference.

[0089] S32. Adjust the speed and working time of the drying fan 1 according to the judgment result.

[0090] Example 3

[0091] This embodiment provides a control method for a garment processing device, used to control the drying program of the garment processing device.

[0092] Specifically, see Figure 1 and Figure 2 The garment processing equipment includes a drying fan 1, an air duct 2, and a condenser 3. Both the drying fan 1 and the condenser 3 are located inside the air duct 2.

[0093] Specifically, the garment processing equipment also includes a housing (not shown in the figure), within which an outer cylinder 4 and an inner cylinder 5 are coaxially arranged, with a gap between them, which forms part of the air duct 2. In addition to the gap between the outer cylinder 4 and the inner cylinder 5, the air duct 2 also includes an outer cavity 23. The two ends of the outer cavity 23 are the air inlet 22 and the air return outlet 21 of the air duct 2, respectively. The outer cavity 23 is located on the outer periphery of the gap between the outer cylinder 4 and the inner cylinder 5 and connects between the air inlet 22 and the air return outlet 21 of the air duct 2. The drying fan 1 and the condenser 3 are both located within the outer cavity 23 of the air duct 2, with the drying fan 1 positioned near the air inlet 22 and the condenser 3 positioned near the air return outlet 21.

[0094] When the garment processing equipment executes the drying program, the clothes to be dried are located inside the inner drum 5. The inner drum 5 rotates around its own axis under the drive of the inner drum drive motor, thereby causing the clothes to tumble. The drying fan 1 blows out high-temperature, low-humidity air, which enters the gap between the outer drum 4 and the inner drum 5 through the air inlet 22, and then enters the inner drum 5 to dry the clothes. Subsequently, the high-temperature, low-humidity air becomes low-temperature, high-humidity air. The low-temperature, high-humidity air flows from the return air inlet 21 into the outer cavity 23. When it passes through the condenser 3, the condenser 3 condenses and dehumidifies the low-temperature, high-humidity air, which then becomes low-temperature, low-humidity air. The low-temperature, low-humidity air flows to the drying fan 1 and is heated again by the drying fan to form high-temperature, low-humidity air. This cycle repeats until the clothes to be dried in the inner drum 5 are completely dried.

[0095] To avoid the clothing processing equipment maintaining a constant drying speed and drying time during the drying process, thus failing to adapt to the specific conditions of the clothes to be dried, this embodiment refers to... Figure 3 The control method for garment processing equipment includes the following steps:

[0096] S1. Set the initial speed of the drying fan 1 and obtain the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2;

[0097] S2. Increase the speed of the drying fan 1 by the set value, and control the drying fan 1 to work at the current speed for a first duration, and then obtain the current humidity difference between the return air vent 21 and the air inlet 22.

[0098] S3. Adjust the speed and working time of the drying fan 1 according to the current humidity difference until the current humidity difference is less than the humidity difference threshold, and then control the drying program to end.

[0099] Optionally, in step S1, the initial speed of the drying fan 1 is set as needed, preferably not exceeding one-quarter of the maximum speed of the drying fan 1. For example, taking a drying fan 1 with a maximum speed of 1000 rpm as an example, its initial speed does not exceed 250 rpm.

[0100] Optionally, in step S2, the setting value is 50 rpm to 200 rpm. For example, the setting value can be selected as 50 rpm, 100 rpm, 150 rpm or 200 rpm.

[0101] Optionally, the first duration is 5 min to 20 min. For example, the first duration can be selected as 5 min, 10 min, 15 min, or 20 min.

[0102] It is understandable that in step S3, the condensing efficiency of condenser 3 (that is, the drying efficiency of the clothes to be dried) can be determined based on the specific situation of the current humidity difference.

[0103] The clothing processing equipment control method provided in this embodiment sets the initial rotation speed of the drying fan 1 in the initial stage of the drying process and obtains the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2. Then, the rotation speed of the drying fan 1 is increased by the set value, and the drying fan 1 operates at the current rotation speed for a first duration. Subsequently, the current humidity difference between the return air inlet 21 and the air inlet 22 is obtained. Next, based on the current humidity difference, the rotation speed and operating time of the drying fan 1 are adjusted until the current humidity difference is less than a humidity difference threshold, at which point the drying process ends. In this way, during the drying process, the rotation speed and operating time of the drying fan 1 can be adaptively adjusted according to the specific conditions of the clothes to be dried, avoiding the technical problem of incomplete drying due to relatively low drying speed and relatively short drying time when there are many clothes to be dried; and also avoiding the technical problem of energy waste due to relatively high drying speed and relatively long drying time when there are few clothes to be dried.

[0104] Furthermore, a first humidity sensor 211 is installed at the return air vent 21, and a second humidity sensor 221 is installed at the air inlet 22. The humidity difference is the value obtained by subtracting the humidity value collected by the second humidity sensor 221 from the humidity value collected by the first humidity sensor 211.

[0105] Specifically, see Figure 4 In this embodiment, step S3, adjusting the speed and operating time of the drying fan 1 according to the current humidity difference, includes the following steps:

[0106] S31. Determine whether the current humidity difference is greater than the previous humidity difference. The previous humidity difference is the humidity difference obtained before the current humidity difference.

[0107] S32. Adjust the speed and working time of the drying fan 1 according to the judgment result.

[0108] It should be noted that in step S31, the current humidity difference is the latest humidity difference updated in real time; the previous humidity difference is the humidity difference before the latest humidity difference.

[0109] Further, see Figure 5 In this embodiment, step S32 includes:

[0110] If the determination result is that the current humidity difference is greater than the previous humidity difference, then determine whether the current speed of the drying fan 1 is less than the maximum speed of the drying fan 1; if the current speed of the drying fan 1 is less than the maximum speed of the drying fan 1, then return to step S2; if the current speed of the drying fan 1 is not less than the maximum speed of the drying fan 1, then control the drying fan 1 to maintain the current speed unchanged and continue to rotate for the second duration.

[0111] If the determination result is that the current humidity difference is not greater than the previous humidity difference, then control the drying fan 1 to maintain the current speed unchanged and continue to rotate for the second duration.

[0112] Optionally, the second duration is 5 min to 20 min. For example, the second duration can be selected as 5 min, 10 min, 15 min, or 20 min.

[0113] Understandably, comparing the current humidity difference with the previous humidity difference allows us to determine the current drying status of the clothes to be dried. For example, if the current humidity difference is not greater than the previous humidity difference, it means that the condensation efficiency remains basically unchanged; if the current humidity difference is greater than the previous humidity difference, it means that the condensation efficiency has improved during the process.

[0114] That is, in this embodiment, when the current humidity difference is greater than the previous humidity difference, and the current speed of the drying fan 1 is less than the maximum speed of the drying fan 1, it is necessary to return to the loop and execute steps S2-S32. In step S2, the speed of the drying fan is increased by the set value again, and the drying fan is controlled to work at the current speed for a first duration. Then, the current humidity difference at the return air inlet and the air inlet is obtained; that is, the latest current humidity difference is obtained at this time; the previous humidity difference at this time is the previous current humidity difference. In this way, the speed and working time of the drying fan can be adjusted multiple times according to the changes in the current humidity difference, so that the actual speed and working time of the drying fan can be adaptively adjusted according to the specific drying conditions of the clothes to be dried.

[0115] When the current humidity difference is greater than the previous humidity difference, and the current speed of the drying fan 1 is greater than the maximum speed of the drying fan 1, the speed of the drying fan cannot be increased further. Therefore, the drying fan 1 is controlled to maintain its current speed and continue to rotate for a second duration to continuously dry the clothes to be dried.

[0116] Alternatively, if the current humidity difference is not greater than the previous humidity difference, it means that the condensation efficiency cannot be improved further. Therefore, the drying fan 1 is controlled to maintain its current speed and continue to rotate for a second duration to continuously dry the clothes to be dried.

[0117] For example, in this embodiment, when executing the clothing processing equipment control method, the following steps are performed:

[0118] Set the initial speed of the drying fan 1 and obtain the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2;

[0119] The speed of the drying fan 1 is increased by a set value, and the drying fan 1 is controlled to operate at the current speed for a first duration. Then, the current humidity difference between the return air vent 21 and the air inlet 22 is obtained.

[0120] Determine if the current humidity difference is greater than the previous humidity difference, where the previous humidity difference is the initial humidity difference; the result is that the current humidity difference is greater than the previous humidity difference.

[0121] Continue to determine whether the current speed of drying fan 1 is less than the maximum speed of drying fan 1; the result is that the current speed of drying fan 1 is less than the maximum speed of drying fan 1.

[0122] At this point, return to step S2, that is, control the speed of the drying fan 1 to increase by the set value, and control the drying fan 1 to work at the current speed for a first duration, and then obtain the current humidity difference between the return air vent 21 and the air inlet 22.

[0123] Then, it is determined whether the current humidity difference is greater than the previous humidity difference, where the previous humidity difference is the value of the previous current humidity difference. If the determination result is that the current humidity difference is not greater than the previous humidity difference, it means that the condensation efficiency remains basically unchanged after increasing the speed of the drying fan 1. Therefore, the drying fan 1 is controlled to maintain the current speed unchanged and continue to rotate for the second duration.

[0124] Once the current humidity difference is less than the humidity difference threshold, the drying process ends.

[0125] Example 4

[0126] See Figure 6 This embodiment provides a control method for a garment processing device, which is a further improvement on the control method for a garment processing device based on Embodiment 3.

[0127] Specifically, in this embodiment, step S3 further includes;

[0128] S33, at the third interval of time, obtain the current humidity difference between the return air vent 21 and the air inlet 22;

[0129] S34. Determine whether the current humidity difference is less than the humidity difference threshold.

[0130] If so, control the drying program to end;

[0131] If not, return to step S33.

[0132] Optionally, the third duration is 5-20 minutes. For example, the third duration can be selected as 5 minutes, 10 minutes, 15 minutes, or 20 minutes.

[0133] Understandably, in step S32, the last step is to control the drying fan 1 to maintain the current speed and continue to rotate for a second duration when the condensation efficiency can no longer be improved, so as to continuously dry the clothes to be dried.

[0134] Then, step S33 is executed. In step S33, at a third time interval, the current humidity difference between the return air vent 21 and the air inlet 22 is obtained; then it is determined whether the current humidity difference is less than the humidity difference threshold.

[0135] If the result indicates that the current humidity difference is less than the humidity difference threshold, it means that the clothes are basically dry, and the drying program can be stopped at this point.

[0136] If the judgment result is that the current humidity difference is not less than the humidity difference threshold, it means that the clothes are not yet dry and need to continue drying. At this time, the drying fan 1 is still working. Return to step S33, after a third time interval, obtain the current humidity difference at the return air vent 21 and the air inlet 22 again, and then execute step S34 to further determine whether the clothes have been dried.

[0137] More preferably, in this embodiment, in step S34, when the current humidity difference is less than the humidity difference threshold, the drying fan 1 is controlled to continue working for a fourth duration, and then the drying program is controlled to end. This setting can further ensure that the clothes are completely dried.

[0138] Optionally, in this embodiment, the humidity difference threshold is no greater than 1%-5%. For example, the humidity difference threshold can be selected as 1%, 2%, 3%, 4%, or 5%.

[0139] Optionally, in this embodiment, the fourth duration is 5-10 minutes. For example, the first duration can be selected as 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, or 10 minutes.

[0140] Example 5

[0141] This embodiment provides a garment processing device.

[0142] Specifically, see Figure 1 and Figure 2 The garment processing equipment includes a drying fan 1, an air duct 2, and a condenser 3. Both the drying fan 1 and the condenser 3 are located inside the air duct 2.

[0143] In this embodiment, the drying program of the clothing processing equipment is controlled by any one of the clothing processing equipment control methods of Embodiment 1 to Embodiment 4.

[0144] The garment processing equipment provided in this embodiment uses the above-described garment processing equipment control method to control the drying process.

[0145] In the initial stage of the drying process, the initial speed of the drying fan 1 is set, and the initial humidity difference between the return air inlet 21 and the air inlet 22 of the air duct 2 is obtained. Then, the speed of the drying fan 1 is increased by the set value, and the drying fan 1 operates at the current speed for a first duration. Subsequently, the current humidity difference between the return air inlet 21 and the air inlet 22 is obtained. Next, based on the current humidity difference, the speed and operating time of the drying fan 1 are adjusted until the current humidity difference is less than the humidity difference threshold, at which point the drying process ends. In this way, during the drying process, the speed and operating time of the drying fan 1 can be adaptively adjusted according to the specific conditions of the clothes to be dried. This avoids the technical problem of incomplete drying due to relatively low drying speed and relatively short drying time when there are many clothes to be dried, and also avoids the technical problem of energy waste due to relatively high drying speed and relatively long drying time when there are few clothes to be dried.

[0146] Specifically, see Figure 1 and Figure 2 The garment processing equipment includes a drying fan 1, an air duct 2, and a condenser 3. Both the drying fan 1 and the condenser 3 are located inside the air duct 2.

[0147] Specifically, the garment processing equipment also includes a housing (not shown in the figure), within which an outer cylinder 4 and an inner cylinder 5 are coaxially arranged, with a gap between them, which forms part of the air duct 2. In addition to the gap between the outer cylinder 4 and the inner cylinder 5, the air duct 2 also includes an outer cavity 23. The two ends of the outer cavity 23 are the air inlet 22 and the air return outlet 21 of the air duct 2, respectively. The outer cavity 23 is located on the outer periphery of the gap between the outer cylinder 4 and the inner cylinder 5 and connects between the air inlet 22 and the air return outlet 21 of the air duct 2. The drying fan 1 and the condenser 3 are both located within the outer cavity 23 of the air duct 2, with the drying fan 1 positioned near the air inlet 22 and the condenser 3 positioned near the air return outlet 21.

[0148] When the garment processing equipment executes the drying program, the clothes to be dried are located inside the inner drum 5. The inner drum 5 rotates around its own axis under the drive of the inner drum drive motor, thereby causing the clothes to tumble. The drying fan 1 blows out high-temperature, low-humidity air, which enters the gap between the outer drum 4 and the inner drum 5 through the air inlet 22, and then enters the inner drum 5 to dry the clothes. Subsequently, the high-temperature, low-humidity air becomes low-temperature, high-humidity air. The low-temperature, high-humidity air flows from the return air inlet 21 into the outer cavity 23. When it passes through the condenser 3, the condenser 3 condenses and dehumidifies the low-temperature, high-humidity air, which then becomes low-temperature, low-humidity air. The low-temperature, low-humidity air flows to the drying fan 1 and is heated again by the drying fan to form high-temperature, low-humidity air. This cycle repeats until the clothes to be dried in the inner drum 5 are completely dried.

[0149] Furthermore, a first humidity sensor 211 is installed at the return air vent 21, and a second humidity sensor 221 is installed at the air inlet 22. The humidity difference is the value obtained by subtracting the humidity value collected by the second humidity sensor 221 from the humidity value collected by the first humidity sensor 211.

[0150] Alternatively, in this embodiment, the condenser 3 is a semiconductor condenser.

[0151] Semiconductor condensers have the advantages of high-efficiency cooling, high-precision temperature control, environmental friendliness and low maintenance costs.

[0152] Specifically, in this embodiment, the condenser 3 includes a condenser box 31, a semiconductor cooling chip 32, condenser blades 33, and heat dissipation blades 34.

[0153] The condenser box 31 is disposed in the air duct 2, and the condenser box 31 has openings at both ends, and both openings are connected to the air duct 2.

[0154] The semiconductor cooling chip 32 is disposed in the condenser box 31.

[0155] The condenser blade 33 is disposed on one side of the semiconductor cooling chip 32 and located inside the condenser box 31.

[0156] The heat dissipation blade 34 is located on the other side of the semiconductor cooling chip 32 and outside the condenser box 31.

[0157] Specifically, the condenser box 31 is a hollow structure open at both ends. Its internal hollow cavity is the condensation chamber, with condensing blades 33 located inside and heat dissipation blades 34 located outside. When the thermoelectric cooler 32 is energized, one side is the low-temperature side and the other side is the heating side. The low-temperature side is in contact with the condensing blades 33, ensuring the condensing blades 33 remain at a low temperature. When low-temperature, high-humidity air passes through the condensation chamber, the condensing blades 33 have a cooling effect, resulting in a lower temperature inside the condensation chamber, thus dehumidifying the air. The heat dissipation blades 34 are in contact with the heating side to dissipate the heat generated by the thermoelectric cooler 32.

[0158] Furthermore, in this embodiment, the condenser 3 also includes a cooling fan 35, which is disposed on the outside of the condenser box 31 and can blow air toward the cooling blades 34. The cooling fan 35 can accelerate the heat dissipation of the cooling blades 34 and improve its heat dissipation effect.

[0159] Since the power of the low-temperature side of the thermoelectric cooler 32 is relatively low, the condenser blade 33 is not suitable for placement at the location with the fastest airflow velocity in the air duct. Preferably, in this embodiment, the condenser blade 33 is located on the side wall of the air duct 2 to avoid the low-temperature, high-humidity airflow blowing directly onto the condenser blade.

[0160] The efficiency of the semiconductor condenser is related to the air velocity (i.e., the rotational speed of the drying fan 1). The lower the air velocity, the lower the evaporation rate; if the air velocity is too high, it will affect the temperature rise of the condensing blades 33, resulting in a decrease in condensation efficiency. In this embodiment, the above-mentioned clothing processing equipment control method can ensure the optimal condensation efficiency of the semiconductor condenser.

[0161] Further, see Figure 2 In this embodiment, the garment processing equipment also includes a drainage system. The drainage system includes a drain pipe 41, the inlet end 411 of which is located at the bottom of the outer cylinder 4 and communicates with the gap between the inner cylinder 5 and the outer cylinder 4, and a drain pump 42 is provided on the drain pipe 41.

[0162] Wastewater discharged from the inner cylinder 5, as well as condensate condensed by the condenser 3, can be discharged through the drain pipe 41.

[0163] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
