[0002] The compressor in the drying equipment is one of the important components to achieve the drying of the drying equipment. When the temperature of the compressor is too high or there is a circuit safety problem, the compressor relay will trip and the compressor will stop working. After the compressor stops working, the compressor needs a long time to cool down before it can resume working.

[0003] In the above implementation, it takes a long time for the compressor to cool down after being disconnected. The compressor can only continue to work when the temperature of the compressor is lower than a certain temperature threshold. This results in a longer drying time for the drying equipment and reduces the heating efficiency of the drying process, affecting the user experience. Summary of the invention

[0004] The present application provides a drying equipment control method, device, drying equipment and storage medium to solve the problem that a long time is required to cool down the compressor after it stops working, resulting in a long drying time of the drying equipment and low heating efficiency during the drying process, which affects the user experience.

[0008] If it is determined that the compressor does not meet the conditions for resuming operation after the cooling time of the compressor reaches a first preset time, the cooling intensity of the compressor cooling device is increased so that the compressor meets the conditions for resuming operation within a second preset time after being shut down; wherein the first preset time is less than the second preset time.

[0009] In a second aspect, the present application further provides a drying equipment control device, which is configured in a drying equipment, wherein the drying equipment includes a compressor and a compressor cooling device, including:

[0015] The scheme of the present application is applied to a drying device, which includes a compressor and a compressor cooling device. It is determined whether the software protection condition is met according to the relevant parameters of the compressor; when it is determined that the software protection condition is met, the compressor is turned off, and the compressor cooling device is turned on to cool the compressor; if it is determined that the compressor does not meet the conditions for resuming work after the cooling time of the compressor reaches the first preset time, the cooling strength of the compressor cooling device is increased so that the compressor meets the conditions for resuming work within the second preset time after being turned off; wherein the first preset time is less than the second preset time.

[0021] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0022] Figure 1 1 is a flow chart of the drying equipment control method provided by the present application. The method can be executed by the drying equipment control device provided by the present application, and the device can be implemented in software and / or hardware. In a specific embodiment, the device can be integrated in the drying equipment. For example, the drying equipment can be a heat pump dryer. The following embodiments will be described by taking the device integrated in the drying equipment as an example. Figure 1 , the method may specifically include the following steps:

[0023] Step 101, determining whether a software protection condition is met based on relevant parameters of the compressor.

[0024] Specifically, the relevant parameters of the compressor are a series of parameters that can characterize the working state of the compressor. Because when an abnormality occurs in the compressor, such as excessive temperature or circuit failure, the relevant parameters of the compressor will also change abnormally. In order to prevent the compressor from experiencing phenomena such as the compressor relay tripping, a software protection condition is set to protect the compressor. When the relevant parameters of the compressor change abnormally, the software protection condition may be met. The software protection condition is a judgment condition based on software settings to perform protection measures on the compressor in advance to avoid the relay tripping phenomenon in the compressor, wherein the execution of protection measures on the compressor refers to a series of operations performed to protect the hardware devices in the compressor, for example, the operations in step 102 and step 103 in the following text. Therefore, it is determined whether the software protection condition is met based on the relevant parameters of the compressor.

[0025] The compressor is installed under the cylinder in the machine shell of the drying equipment, and can transport heat energy to the cylinder of the drying equipment. The drying equipment evaporates the water in the material in the cylinder through heat energy to form water vapor. The water vapor is cooled and flows out through the condenser, thereby achieving the purpose of drying the material.

[0026] Optionally, determining whether the software protection condition is met according to relevant parameters of the compressor may be implemented through steps 1011 to 1012 , or may be implemented through steps 1013 to 1014 .

[0027] In a possible implementation, the relevant parameters of the compressor include the internal temperature and the external temperature of the compressor.

[0028] Step 1011, obtaining the internal temperature and external temperature of the compressor.

[0029] Specifically, the internal temperature of the compressor is the temperature detected inside the compressor when the compressor is working, and the external temperature of the compressor is the temperature detected outside the compressor when the compressor is working, that is, the temperature inside the drying equipment drum. The internal temperature and external temperature of the compressor are obtained by temperature sensors installed inside and outside the compressor.

[0030] Exemplarily, the internal temperature of the compressor may be obtained by a temperature sensor installed at the exhaust port of the compressor, and the external temperature of the compressor may be obtained by a temperature sensor installed at the outlet of the condenser.

[0031] Step 1012: When the internal temperature is greater than or equal to the first preset temperature, and / or the external temperature is greater than or equal to the second preset temperature, it is determined that the software protection condition is met.

[0032] Specifically, the first preset temperature is a temperature threshold at which the preset internal temperature reaches the software protection condition, and the second preset temperature is a temperature threshold at which the preset external temperature reaches the software protection condition.

[0033] Optionally, the first preset temperature and the second preset temperature are values ​​determined according to empirical data.

[0034] Optionally, the first preset temperature and the second preset temperature can also be adjusted according to the usage scenario of the drying device. For example, the first preset temperature and the second preset temperature can be determined according to the current ambient temperature outside the drying device. For example, the current ambient temperature is obtained by a temperature sensor installed outside the drying device, and a mapping relationship between the ambient temperature and the first preset temperature and a mapping relationship between the ambient temperature and the second preset temperature are generated by historical experience data. Then, the first preset temperature and the second preset temperature corresponding to the current ambient temperature are determined based on the mapping relationship between the ambient temperature and the first preset temperature and the mapping relationship between the ambient temperature and the second preset temperature. This implementation method can determine the software protection conditions according to the current environment, so that the drying device control method can be applied in different environments, improves the flexibility of the drying device control method, and expands the application scenarios of the drying device.

[0035] When the internal temperature is greater than or equal to the first preset temperature, and / or the external temperature is greater than or equal to the second preset temperature, it is determined that the software protection condition is met and the compressor needs to be software protected.

[0036] Optionally, when the internal temperature is greater than or equal to a third preset temperature, and / or the external temperature is greater than or equal to a fourth preset temperature, the compressor cooling device is turned on to cool the compressor.

[0037] The third preset temperature is lower than the first preset temperature, and the fourth preset temperature is lower than the second preset temperature.

[0038] Specifically, when the internal temperature is greater than or equal to the third preset temperature, and / or the external temperature is greater than or equal to the fourth preset temperature, the compressor cooling device is turned on to continuously cool the compressor, so that the time for the internal temperature of the compressor to reach the first preset temperature is delayed, and the time for the external temperature of the compressor to reach the second preset temperature is also delayed, so that the compressor can complete the drying without meeting the software protection condition.

[0039] In another possible implementation manner, the relevant parameters of the compressor include electrical parameters of the compressor.

[0040] Step 1013, obtaining electrical parameters of the compressor.

[0041] Specifically, the electrical parameters of the compressor may include at least one of the parameters of the compressor such as rotation speed, voltage, power, etc. The electrical parameters of the compressor are obtained by monitoring various parameters of the compressor when it is working.

[0042] Step 1014: When the electrical parameters of the compressor meet the preset conditions, it is determined that the software protection condition is met.

[0043] Specifically, the preset condition may include at least one of the following: the speed of the compressor reaches a speed threshold, the voltage reaches a voltage threshold, or the power reaches a power threshold, etc. When the electrical parameters of the compressor meet the preset conditions, it means that an abnormal situation has occurred in the operation of the compressor, the electrical parameters have also undergone abnormal changes, and the software protection conditions have been met.

[0044] Optionally, the rotation speed threshold, voltage threshold and power threshold in the preset conditions are values ​​determined based on empirical data.

[0045] Optionally, the speed threshold, voltage threshold and power threshold in the preset conditions can also be adjusted, for example, the speed threshold, voltage threshold and power threshold can be determined according to the model or design parameters of the compressor. For example, by obtaining the model of the compressor, the current standard speed, current rated voltage and current rated power of the compressor are determined. The mapping relationship between the standard speed and the speed threshold, the mapping relationship between the rated voltage and the voltage threshold, and the mapping relationship between the rated power and the power threshold are generated by historical experience data. Then, according to the mapping relationship between the standard speed and the speed threshold, the mapping relationship between the rated voltage and the voltage threshold, and the mapping relationship between the rated power and the power threshold, the speed threshold corresponding to the current standard speed of the compressor, the voltage threshold corresponding to the current rated voltage, and the power threshold corresponding to the current rated power are determined. This implementation method can realize the determination of software protection conditions according to the model or design parameters of the current compressor, so that the drying equipment control method can be applied to different drying equipment, expanding the application scenario of the drying equipment control method.

[0046] Step 102: When it is determined that the software protection condition is met, the compressor is turned off, and a compressor cooling device is turned on to cool the compressor.

[0047] Specifically, after determining that the software protection condition is met, the compressor is turned off and the compressor cooling device is turned on. The compressor cooling device is a device installed inside the drying device that can provide flowing air to the compressor to reduce the temperature of the compressor. For example, the compressor cooling device can be a heat dissipation fan installed near the compressor.

[0048] Exemplarily, when the internal temperature of the compressor is equal to the first preset temperature, it is determined that the software protection condition is met. At this time, the compressor is turned off, and a heat dissipation fan installed near the compressor is turned on to cool the compressor.

[0049] Step 103: If it is determined that the compressor does not meet the conditions for resuming operation after the compressor cooling time reaches the first preset time, the cooling intensity of the compressor cooling device is increased so that the compressor meets the conditions for resuming operation within a second preset time after being shut down.

[0050] Among them, the first preset time length is shorter than the second preset time length.

[0051] Specifically, the compressor recovery condition is a condition under which the compressor can resume operation after the abnormal condition is resolved.

[0052] Optionally, the resumption working condition may be that the temperature of the compressor is less than or equal to a preset resumption working temperature threshold.

[0053] Optionally, the condition for resuming work may also be that the temperature difference between the temperature of the compressor and the current ambient temperature is less than a threshold value. Based on this, the current ambient temperature can be obtained through a temperature sensor outside the drying device. For example, the condition for resuming work of the compressor may be that the temperature difference between the temperature of the compressor and the current ambient temperature is equal to 0. After the duration of cooling the compressor reaches a first preset duration, if the compressor still does not meet the condition for resuming work, the cooling intensity of the compressor cooling device is increased to increase the cooling speed of the compressor, and finally the condition for resuming work can be met within a second preset duration after the compressor is turned off, and work can be restarted to complete the drying process of the drying device.

[0054] It should be noted that the temperature of the compressor in this embodiment may be the internal temperature of the compressor and / or the external temperature of the compressor.

[0055] For example, the first preset time is 2 minutes, and the second preset time is 3 minutes. After the compressor is cooled for 2 minutes, the internal temperature of the compressor is still greater than the current ambient temperature. At this time, the cooling strength of the compressor cooling device is increased, for example, the speed of the cooling fan is increased to increase the cooling speed of the compressor. The increased cooling speed can make the internal temperature of the compressor equal to the current ambient temperature within 1 minute.

[0056] The scheme of the present application is applied to a drying device, which includes a compressor and a compressor cooling device. It is determined whether the software protection condition is met according to the relevant parameters of the compressor; when it is determined that the software protection condition is met, the compressor is turned off, and the compressor cooling device is turned on to cool the compressor; if it is determined that the compressor does not meet the conditions for resuming work after the cooling time of the compressor reaches the first preset time, the cooling strength of the compressor cooling device is increased so that the compressor meets the conditions for resuming work within the second preset time after being turned off; wherein the first preset time is less than the second preset time. That is, the scheme of the present application, on the one hand, when the relevant parameters of the compressor meet the software protection condition, the compressor is turned off and cooled, which avoids the tripping of the compressor relay and enhances the safety of the compressor when it is used. On the other hand, by adding a compressor cooling device and adjusting the cooling intensity of the compressor cooling device, it is ensured that the compressor can be cooled at a faster speed, so that the compressor can meet the conditions for resuming work within the second preset time after being shut down, that is, it can meet the conditions for resuming work in a shorter time, reducing the cooling time of the compressor, thereby avoiding the problem of increased drying time of the drying equipment due to long-term shutdown of the compressor for cooling, reducing the drying time of the drying equipment, increasing the heating efficiency of the dryer, and improving the user experience.

[0057] Figure 2 is another flow chart of the drying equipment control method provided by the present application. Figure 1 Based on the illustrated embodiment and various optional implementation schemes, the cooling strength of the compressor cooling device is increased in detail, and the process after the drying is completed is described in detail. Figure 2 As shown, the method may include the following steps:

[0058] Step 201, determining whether a software protection condition is met based on relevant parameters of the compressor.

[0059] Specifically, the relevant parameters of the compressor are a series of parameters that can characterize the working state of the compressor. Because when the compressor is abnormal, such as overtemperature or circuit failure, the relevant parameters of the compressor will also change abnormally. In order to prevent the compressor from tripping, etc., a software protection condition is set to protect the compressor. When the relevant parameters of the compressor change abnormally, the software protection condition may be reached. Therefore, it is determined whether the software protection condition is reached based on the relevant parameters of the compressor.

[0060] Step 202: When it is determined that the software protection condition is met, the compressor is turned off, and a compressor cooling device is turned on to cool the compressor.

[0061] Specifically, after determining that the software protection condition is met, the compressor is turned off and the compressor cooling device is turned on. The compressor cooling device is a device installed inside the drying device that can provide flowing air to the compressor to reduce the temperature of the compressor. For example, the compressor cooling device can be a heat dissipation fan installed near the compressor.

[0062] Step 203: When the duration of cooling the compressor is less than a first preset duration, control a first number of fans among a plurality of fans of the compressor cooling device to operate at a first wind speed.

[0063] Among them, the cooling force of the compressor cooling device includes wind speed, and the compressor cooling device includes multiple fans.

[0064] Exemplarily, the compressor cooling device has two fans, and the first preset duration is 2 minutes. When the duration of cooling the compressor is less than 2 minutes, the two fans of the compressor cooling device are controlled to operate at a first wind speed.

[0065] Step 204: If it is determined that the compressor does not meet the conditions for resuming operation after the compressor cooling time reaches the first preset time, the cooling intensity of the compressor cooling device is increased so that the compressor meets the conditions for resuming operation within a second preset time after being shut down.

[0066] Specifically, after the cooling time of the compressor reaches a first preset time, if the compressor still does not meet the conditions for resuming work, the cooling intensity of the compressor cooling device is increased to increase the cooling speed of the compressor, and finally the conditions for resuming work can be met within a second preset time after the compressor is turned off, and work can be restarted to complete the drying process of the drying equipment.

[0067] Optionally, the cooling intensity of the compressor cooling device also includes the temperature of the gas delivered to the compressor by the compressor cooling device, and the compressor cooling device also includes a cold air module. The second number of fans are controlled to operate at the second wind speed, and the cold air module is controlled to be turned on.

[0068] The second wind speed is greater than the first wind speed, the cold air module is used to reduce the temperature of the gas delivered to the compressor by the compressor cooling device, and the second number is greater than or equal to the first number. For example, the cold air module can be a heat absorbing material.

[0069] Specifically, the cooling intensity can be increased by the following methods: Method 1, the cooling intensity of the compressor can be increased by increasing the number of fans in the cooling module; Method 2, the cooling intensity of the compressor can be increased by increasing the wind speed of the fans in the cooling module; Method 3, the cooling intensity of the compressor can be increased by turning on the cold air module and reducing the temperature of the gas delivered to the compressor by the compressor cooling device; Method 4, combining the above methods 1 and 2 to increase the cooling intensity of the compressor; Method 5, combining the above methods 1 and 3 to increase the cooling intensity of the compressor; Method 6, combining the above methods 2 and 3 to increase the cooling intensity of the compressor; Method 7, combining the above methods 1, 2 and 3 to increase the cooling intensity of the compressor.

[0070] Exemplarily, the compressor cooling device includes 3 fans and a cold air module. The first preset time is 2 minutes, and the second preset time is 3 minutes. When the time for cooling the compressor is less than 2 minutes, the 2 fans of the compressor cooling device are controlled to operate at the first wind speed. After the time for cooling the compressor reaches 2 minutes, the compressor does not meet the conditions for resuming work. The 3 fans of the compressor cooling device are controlled to operate at the second wind speed, and the cold air module is turned on to reduce the temperature of the gas delivered to the compressor by the compressor cooling device, so that the cooling speed of the compressor is increased. The increased cooling speed can make the compressor meet the conditions for resuming work within 1 minute.

[0071] Optionally, the cooling strength of the compressor cooling device also includes the position of the air outlet. Increasing the cooling strength of the compressor cooling device also includes: controlling at least one fan of the second number of fans to move toward the compressor, and / or controlling the cold air module to move toward the compressor.

[0072] Specifically, the closer the air outlet of the fan is to the compressor, the greater the wind force the compressor bears, and the faster the compressor cools down. Therefore, the cooling force of the compressor can be increased by adjusting the air outlet position of the compressor cooling device.

[0073] Exemplarily, the compressor cooling device includes three fans and a cold air module. Any one of the three fans can be controlled to move toward the compressor, and / or the air outlet of the cold air module can be controlled to move toward the compressor.

[0074] Step 205, when the compressor meets the conditions for resuming operation, the compressor cooling device is turned off and the compressor is turned on again for drying.

[0075] Specifically, when the compressor meets the resumption of working conditions, it means that the compressor can restart working. For example, when the internal temperature of the compressor is less than or equal to the current ambient temperature, the compressor cooling device is turned off and the compressor is restarted for drying.

[0076] Step 206, after the drying is completed, turn on the cooling device in the drum of the drying equipment, and / or control the compressor to enter the refrigeration mode, and deliver gas to the drum of the drying equipment until the temperature in the drum of the drying equipment is less than or equal to the current ambient temperature, turn off the cooling device in the drum of the drying equipment, and / or turn off the compressor.

[0077] Specifically, after drying is completed, the temperature inside the drying device is relatively high, and the user may be burned by the high temperature when taking items out of the drying device. The in-drum cooling device of the drying device is a device installed around the drum of the drying device for cooling the drum of the drying device. At this time, the in-drum cooling device of the drying device is turned on to reduce the temperature inside the drum of the drying device, and / or the compressor is controlled to enter the cooling mode and deliver gas to the drum of the drying device until the temperature inside the drum of the drying device is less than or equal to the current ambient temperature, and the in-drum cooling device of the drying device is turned off, and / or the compressor is turned off. After the temperature inside the drum is less than or equal to the current ambient temperature, the user will not be exposed to the higher temperature air inside the drum, thereby improving safety.

[0078] For example, after drying, the temperature inside the dryer reaches 60° C. and the ambient temperature is 24° C. The compressor is controlled to enter the cooling mode and deliver gas to the drum of the drying device until the temperature inside the dryer drops to 24° C. The compressor is turned off to facilitate users to take clothes out of the dryer.

[0079] It should be understood that although Figure 2 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages do not necessarily have to be executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages does not have to be performed sequentially, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0080] The solution of the present application is applied to drying equipment, which includes a compressor and a compressor cooling device. The cooling strength of the compressor cooling device can be increased by increasing the wind speed of the fan in the compressor cooling device, increasing the number of fans, turning on the cold air module, adjusting the position of the air outlet, etc., to ensure that the compressor can be cooled at a faster speed, so that it can meet the conditions for resuming work in a shorter time, shortening the drying time. After the drying is completed, the temperature in the barrel of the drying equipment is lowered by turning on the cooling device in the barrel of the drying equipment or turning on the cooling mode of the compressor, thereby avoiding the possibility of users being exposed to high-temperature air and improving the user experience.

[0081] Figure 3 is a structural diagram of a drying equipment control device provided in the present application, and the device is suitable for executing the drying equipment control method provided in the present application. The drying equipment control device is configured in the drying equipment, and the drying equipment includes a compressor and a compressor cooling device, such as Figure 3 As shown, the device may specifically include:

If the cooling time of the compressor reaches a first preset time, and it is determined that the compressor does not meet the resumption of work condition, the intensity increasing module 303 increases the cooling intensity of the compressor cooling device so that the compressor meets the resumption of work condition within a second preset time after being shut down, and is also used for:

[0092] When the duration of cooling the compressor is less than the first preset duration, a first number of fans among the plurality of fans of the compressor cooling device are controlled to operate at a first wind speed.

[0095] In one embodiment, the cooling force of the compressor cooling device also includes the air outlet position, and the force increasing module 303 increases the cooling force of the compressor cooling device, and further includes:

[0096] Control at least one of the second number of fans to move toward the compressor, and / or control the cold air module to move toward the compressor.

[0099] The refrigeration module is used to turn on the cooling device in the drum of the drying equipment after drying is completed, and / or control the compressor to enter the refrigeration mode, and transport gas to the drum of the drying equipment until the temperature in the drum of the drying equipment is less than or equal to the current ambient temperature, turn off the cooling device in the drum of the drying equipment, and / or turn off the compressor.

[0100] Those skilled in the art can clearly understand that for the convenience and simplicity of description, only the division of the above-mentioned functional modules is used as an example for illustration. In actual applications, the above-mentioned functions can be assigned to different functional modules as needed, that is, the internal structure of the device is divided into different functional modules to complete all or part of the functions described above.
