[0022] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0023] Figure 1 The flowchart of the control method of the drying device provided by some embodiments of the present application is shown. Although the logical order is shown in the flowchart, in some cases, the operations shown or described may be performed in a different order than that shown in the drawings. The flow of the control method may include:

[0024] S101, monitoring the current humidity inside the drying equipment.

[0025] When the drying equipment is running, the internal drum rotates, and the items to be dried are placed in the drum. The fan of the drying equipment blows high-temperature, low-humidity air into the drum, and the air flows away the moisture inside the drum to dry the items. By monitoring the humidity inside the drying equipment, the degree of drying can be determined.

[0026] The current humidity refers to the humidity value when the monitoring device collects humidity data, and the current humidity may change gradually over time. For example, the data collection location of the current humidity may be at the exhaust port, and the degree of drying may be determined by monitoring the air humidity at the exhaust port. For another example, the data collection location of the current humidity may also be inside the drum.

[0027] The monitoring of the current humidity may be performed by collecting humidity data at preset time intervals.

[0028] S102: When the current humidity rises to exceed a first humidity threshold, increasing the current fan speed of the drying device to a first fan speed.

[0029] During the drying process, the current humidity inside the drying device will experience a process of rising first and then falling. When the current humidity rises to exceed the first threshold, it means that the humidity in the drum will continue to rise in the next period of time. At this time, the current fan speed can be increased to make the air in the drum circulate quickly and take away the water vapor.

[0030] The first humidity threshold may be a preset fixed value or a variable value adjusted according to load conditions.

[0031] The first fan speed may be a preset fixed value or a variable value adjusted according to load conditions.

[0032] S103: When the current humidity drops below a second humidity threshold, the current fan speed is reduced to a second fan speed, wherein the second fan speed is lower than the first fan speed.

[0033] As mentioned above, the current humidity inside the drying equipment will experience a process of first rising and then falling. After the current humidity enters the falling stage, the humidity in the barrel will gradually decrease. When the current humidity drops to less than the second threshold, the temperature in the barrel is at a high level because it has been dried for a period of time. Even if the current fan speed is appropriately reduced, the water vapor in the barrel can be taken away quickly. Therefore, after the current humidity drops to less than the second humidity threshold, the current fan speed can be reduced to balance the drying speed while reducing energy consumption.

[0034] The second humidity threshold may be a preset fixed value or a variable value adjusted according to load conditions. In some embodiments, the second humidity threshold may be the same value as the first humidity threshold.

[0035] The second fan speed may be a preset fixed value or a variable value adjusted according to the load condition. After the current humidity rises to exceed the first humidity threshold, the current fan speed rises to the first fan speed, and then maintains the first fan speed. After the current humidity has gone through the rising stage and entered the falling stage, after the current humidity drops to less than the second humidity threshold, the current fan speed may drop from the first fan speed to the second fan speed. The second fan speed is less than the first fan speed.

[0036] Some embodiments of the present application provide a control method for a drying device, comprising: monitoring the current humidity inside the drying device; when the current humidity rises to exceed a first humidity threshold, increasing the current fan speed of the drying device to a first fan speed; and when the current humidity drops to less than a second humidity threshold, dropping the current fan speed to a second fan speed, wherein the second fan speed is less than the first fan speed. Some embodiments of the present application provide a control method for a drying device that can increase the drying speed.

[0037] In some embodiments, after operation S103, the following steps may also be performed:

[0038] When the current humidity drops below the third humidity threshold, the drying is terminated.

[0039] During the drying process, the humidity change in the drum is monitored in real time. When the current humidity drops below the third humidity threshold, it indicates that the humidity in the drum has reached a lower level and the drying can be ended. The third humidity threshold is less than the second humidity threshold.

[0040] The control method of the drying equipment provided in some embodiments of the present application can monitor the current humidity in the drum in real time, and can terminate the drying in time when the current humidity is less than a third humidity threshold, so as to avoid over-drying of the items.

[0041] Figure 2 The flowchart of the control method of the drying device provided by some embodiments of the present application is shown. Although the logical order is shown in the flowchart, in some cases, the operations shown or described may be performed in a different order than that shown in the drawings. The flow of the control method may include:

[0042] S201, pre-drying is performed according to a preset fan speed.

[0043] Among them, pre-drying can be a process performed before the formal drying process begins, and can be used to determine relevant operating parameters of the drying equipment in the formal drying stage.

[0044] In the pre-drying stage, the drying device operates with preset parameters. For example, the drying device dries at a preset drum speed and a preset fan speed. In some embodiments, the compressor may not be started in the pre-drying stage.

[0045] S202, determining the load mass according to the motor power of the drying equipment.

[0046] After the pre-drying starts, the motor power is collected, wherein the motor power may be the power of the motor that drives the drum and the fan at the same time, or the power of the motor that drives the fan alone.

[0047] In some embodiments, a pre-established mapping table of motor power and load mass (load weight) may be stored in the drying device, and the load mass may be obtained by searching the mapping table according to the motor power.

[0048] In other embodiments, the load mass may be calculated based on a functional relationship between the motor power and the load mass.

[0049] S203. Determine an initial fan speed according to the load mass.

[0050] The initial fan speed is the initial value of the fan speed after the drying equipment enters the formal drying process.

[0051] When the load inside the drying equipment is small (the load mass is small), the demand for circulating air volume is low, and a lower fan speed can be used. When the load inside the drying equipment is large, the wind resistance is large, the demand for circulating air volume is high, and a higher fan speed is required. Therefore, the corresponding initial fan speed can be determined according to the load mass.

[0052] In some embodiments, when the load mass is less than or equal to half of the nominal load, the initial fan speed is determined to be a first initial value; when the load mass is greater than half of the nominal load, the initial fan speed is determined to be a second initial value, wherein the second initial value is greater than the first initial value.

[0053] In some embodiments, different mass levels of the load mass may be preset, and after the load mass falls into a certain mass level, the initial fan speed is determined to be the speed corresponding to the mass level.

[0054] In other embodiments, the initial fan speed is determined according to a mapping relationship between the load mass and the initial fan speed.

[0055] Some embodiments of the present application provide a control method for drying equipment, which determines the load mass according to the motor power during the pre-drying process, and then flexibly determines the initial fan speed according to the load mass, thereby being able to adapt to different load conditions.

[0056] Figure 3 The flowchart of the control method of the drying device provided by some other embodiments of the present application is shown. Although the logical order is shown in the flowchart, in some cases, the operations shown or described may be performed in a different order than that shown in the drawings. The flow of the control method may include:

[0057] S301, pre-drying is performed according to a preset fan speed.

[0058] S302, determining the initial circulation air volume according to the motor power.

[0059] After the pre-drying starts, the motor power is collected, wherein the motor power may be the power of the motor that drives the drum and the fan at the same time, or the power of the motor that drives the fan alone.

[0060] The initial circulating air volume refers to the circulating air volume in the drum when the pre-drying operation parameters are used.

[0061] In some embodiments, a pre-established mapping table between motor power and initial circulation air volume may be stored in the drying device, and the initial circulation air volume may be obtained by querying the mapping table according to the motor power.

[0062] In other embodiments, the initial circulating air volume may be calculated based on a functional relationship between the motor power and the initial circulating air volume.

[0063] S303. Determine the current circulation air volume according to the initial circulation air volume.

[0064] Among them, the current circulating air volume is the actual circulating air volume in the drum after entering the formal drying process, and the current circulating air volume can change with the change of the fan speed. Under the same other conditions, the greater the current fan speed, the greater the corresponding current circulating air volume.

[0065] In some embodiments, the current circulating air volume is determined according to the initial circulating air volume, the preset fan speed and the current fan speed. The initial circulating air volume and the preset fan speed are the operating parameters of the pre-drying stage, and the current fan speed is the actual fan speed after entering the formal drying process. Based on the fan similarity principle, the ratio of the current circulating air volume to the initial circulating air volume is equal to the ratio of the current fan speed to the preset fan speed, and the current circulating air volume can be obtained accordingly.

[0066] In some embodiments, after operation S303, the following steps may also be performed:

[0067] S304: Determine the target compressor speed of the drying equipment according to the current circulating air volume.

[0068] The refrigerant can be compressed to high temperature and high pressure by the compressor of the drying equipment, and then enter the heat release device to exchange heat with the surrounding air, so that the air is heated and the refrigerant is cooled and liquefied. The heated air can be blown into the drum by the fan. The liquefied high-pressure refrigerant is decompressed by the throttling mechanism to become a low-temperature and low-pressure liquid refrigerant, and then enters the heat absorber to exchange heat with the surrounding air, dehumidify and cool the high-humidity air flowing out of the drum, and the refrigerant is heated to become a vapor refrigerant and return to the compressor.

[0069] When the current circulating air volume is at a low level, the heat exchange demand is also low, and a lower compressor speed can be used. If a high compressor speed is still maintained at this time, the compressor may overheat and be damaged.

[0070] The target compressor speed is the speed of the compressor in the formal drying process. The target compressor speed can be adjusted according to the change of the current circulating air volume.

[0071] In some embodiments, when the current circulating air volume is greater than the circulating air volume threshold, the target compressor speed is determined to be the first compressor speed; or when the current circulating air volume is less than the circulating air volume threshold, the target compressor speed is determined to be the second compressor speed, wherein the second compressor speed is less than the first compressor speed.

[0072] In some embodiments, different air volume levels of the current circulating air volume may be preset, and after the current circulating air volume falls into a certain air volume level, the target compressor speed is determined to be the speed corresponding to the air volume level.

[0073] In other embodiments, the target compressor speed is determined based on a mapping relationship between the current circulating air volume and the target compressor speed.

[0074] In some embodiments of the present application, a control method for drying equipment is provided, in which the initial circulating air volume is determined according to the motor power during the pre-drying process, and then the current circulating air volume is determined according to the initial circulating air volume. Furthermore, the compressor speed can be adjusted according to the current circulating air volume, which can reduce energy consumption while avoiding overheating and damage to the compressor.

[0075] Figure 4 An example diagram of a control method for a drying device provided by some other embodiments of the present application is shown. The process of the control method may be as follows:

[0076] Pre-drying is performed according to a preset fan speed. Other operating parameters of the pre-drying stage may also be preset, such as the drum speed. The compressor may not be started during the pre-drying stage.

[0077] The load mass and the initial circulation air volume are determined according to the motor power of the drying device. The load mass and the initial circulation air volume can be determined by searching a pre-established mapping table.

[0078] The initial fan speed is determined according to the load mass. The initial fan speed is the fan speed when the formal drying process begins.

[0079] The current circulating air volume is determined according to the initial circulating air volume, the preset fan speed and the current fan speed. When entering the drying process, the current fan speed is the initial fan speed.

[0080] It is determined whether the current circulating air volume is greater than the circulating air volume threshold. If so, the target compressor speed is determined to be a first compressor speed, and the compressor is operated at the first compressor speed; if not, the target compressor speed is determined to be a second compressor speed, and the compressor is operated at the second compressor speed. The second compressor speed is less than the first compressor speed.

[0081] During the formal drying process, monitor the current humidity inside the drying equipment.

[0082] When the current humidity rises to exceed the first humidity threshold, the current fan speed of the drying device is increased to the first fan speed. At this time, it can be determined whether the current circulating air volume is greater than the circulating air volume threshold. If so, the target compressor speed is determined to be the first compressor speed, and the compressor operates at the first compressor speed; if not, the target compressor speed is determined to be the second compressor speed, and the compressor operates at the second compressor speed.

[0083] When the current humidity drops below the second humidity threshold, the current fan speed is reduced to the second fan speed. At this time, it can be determined whether the current circulating air volume is greater than the circulating air volume threshold. The determination method and the subsequent process are the same as above and will not be repeated here.
