Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0042] This application provides a garment processing device and its drying control method, apparatus, and computer storage medium, which will be described in detail below.

[0043] With technological advancements and increasing functional demands in household life, heat pump clothes dryers have become a popular product in the market. A heat pump clothes dryer is a type of clothing processing equipment with drying capabilities. For example, a washer-dryer combo combines washing, dehydration, and heat pump drying functions, making it widely popular among consumers. However, in current technology, most heat pump washer-dryer combos are integrated designs, meaning the washing module and heat pump drying module share a single enclosure. This high degree of integration results in a compact internal space, limiting the size and installation space of the core heat exchanger in the heat pump drying module, leading to a longer drying time. Furthermore, the heat pump system takes a long time to reach its optimal operating temperature, which also affects the overall drying time.

[0044] Therefore, this application provides a garment processing device with a drying function. For example, the garment processing device is a drum dryer or a drum washer-dryer combo. Specifically, the garment processing device includes a drum, an air duct, a heat pump system, and an auxiliary heating device. The drum defines the space for the load. The drum is rotatably mounted inside the garment processing device and is driven to rotate by the device's drive mechanism. The air duct is located inside the device and communicates with the drum for air circulation. The heat pump system includes a compressor and a condenser. The compressor compresses the medium to generate high-pressure, high-temperature gas, which is transported to the condenser through a pipe. Driven by a fan, the air in the drum is transported through the air duct to the condenser for heat exchange, heating the air. The heated air is then returned to the drum through the air duct, further increasing the gas temperature in the drum.

[0045] The auxiliary heating device is used to compensate for the heating of hot air, further increasing the heating rate of the hot air to reduce the heating time and improve drying efficiency. The auxiliary heating device includes a positive temperature coefficient (PTC) heater. PTC heaters have advantages such as rapid heating, reduced current after reaching the set temperature (saving energy), and automatic temperature control to prevent overheating once the temperature reaches a certain value, meeting the requirements of heat pump washer-dryer combos for strict temperature control and low energy consumption. The auxiliary heating device is installed inside the air duct, near the air inlet of the drum. After the heat pump drying mode is activated, it assists in heating, causing the temperature of the circulating air inside the drum to rise, helping the heat pump system quickly reach the optimal operating temperature, reducing drying time, and improving drying efficiency. This helps solve the problem of long drying times caused by insufficient heat exchange due to limited space, small condenser size, and limited installation space.

[0046] The technical solution of this application further provides a drying control method to solve the technical problem of poor drying quality and environmental unfriendliness caused by the mismatch of operating parameters between the heat pump system and the auxiliary heating device. During the operation of the heat pump system and the auxiliary heating device, their operating states directly affect the temperature rise rate and heating time of the gas inside the drum, thus affecting the drying quality and efficiency of the load. For example, if both the heat pump system and the auxiliary heating device operate at higher parameters, the drying efficiency will increase, but it may cause wrinkles and deformation of the clothes; conversely, if both the heat pump system and the auxiliary heating device operate at lower parameters, the clothes may not be able to dry properly.

[0047] The garment processing equipment further includes a controller, which is signal-connected to the heat pump system and the auxiliary heating device. The controller executes the drying control method provided in the embodiments of this application. Specifically, refer to... Figure 1 The diagram shown is a flowchart of one embodiment of the drying control method in this application. The drying control method includes:

[0048] S100, in response to the drying command, controls the heat pump system to start;

[0049] Drying commands can be issued by the user to the garment handling device, such as through voice input (e.g., "Hey T, start drying"), app input, or keypad input. Drying commands can also be generated automatically when the garment handling device enters the drying program after washing. Upon receiving a drying command, the heat pump system is activated. When the heat pump system starts, the compressor drives the medium to circulate within the medium pipeline, and the fan drives the air inside the drum to circulate and exchange heat with the condenser, thereby heating the air inside the drum.

[0050] In some embodiments, the drum may rotate at a preset speed during drying, depending on user selection; in other embodiments, the drum may not rotate during drying.

[0051] S200, Obtain the status parameters of the heat pump system;

[0052] In this embodiment, after the heat pump system is started, its status parameters are acquired; these status parameters characterize the heating rate of the air inside the drum. In some embodiments, the status parameters are acquired after the heat pump system has been running stably. For example, the status parameters are acquired after the heat pump system has been running for a preset period of time, so as to accurately match the operating parameters of the auxiliary heating device, ensuring that the status parameters and operating parameters are matched. This helps to prevent damage to the dried clothes and also improves drying efficiency.

[0053] S300, determine the operating parameters of the auxiliary heating device based on the status parameters of the heat pump system;

[0054] In this embodiment, the operating parameters are determined based on the state parameters, so that the auxiliary heating device can operate according to the working state of the heat pump system. This allows the auxiliary heating device to provide precise auxiliary heating based on the working state of the heat pump system, which helps to avoid damaging the dried clothes and also improves the drying efficiency.

[0055] S400, control the auxiliary heating device to start and operate with the stated operating parameters.

[0056] After the heat pump system is running, the auxiliary heating device is controlled to operate according to the operating parameters determined by the state parameters of the heat pump system. This provides precise assistance to the hot air heated by the heat pump system, thereby raising the temperature of the hot air again. This helps to prevent damage to the dried clothes and also improves the drying efficiency.

[0057] In the technical solution of this application embodiment, in response to the drying command, the heat pump system is started; after the heat pump system is started, the status parameters of the heat pump system are acquired; the operating parameters are determined according to the status parameters, so that the auxiliary heating device can operate according to the working status of the heat pump system, so that the auxiliary heating device operates with the operating parameters determined by the status parameters of the heat pump system and thus performs precise auxiliary heating, which helps not damage the dried clothes and also helps to improve the drying efficiency.

[0058] In some embodiments, a mapping relationship exists between status parameters and operating parameters, which is determined through performance testing experiments. This mapping relationship is stored in the memory of the garment processing device. During drying, the operating parameters are determined by invoking the mapping relationship and retrieving the status parameters.

[0059] As an optional implementation of the above embodiments, the heat pump system includes a compressor and a condenser; the status parameters include the exhaust temperature of the compressor and the outlet temperature of the condenser. Figure 2 As shown, determining the operating parameters of the auxiliary heating device based on the state parameters of the heat pump system includes:

[0060] S310, determine the operating parameters of the auxiliary heating device based on the exhaust temperature and / or the outlet temperature.

[0061] In this embodiment, the compressor's exhaust temperature and / or the condenser's outlet temperature directly affect the heating rate and efficiency of the air. Therefore, by determining the operating parameters of the auxiliary heating device based on the exhaust temperature and / or the outlet temperature, the operating parameters are matched to the exhaust temperature and / or the outlet temperature. This allows for targeted thermal compensation of the hot air in the heat pump system, helping to prevent damage to dried clothes and improve drying efficiency. For example, when both the exhaust and outlet temperatures are high, the required compensation amount of hot air is smaller, and the operating parameters are lower, preventing the temperature from rising too quickly and damaging the quality of the clothes. Conversely, when both the exhaust and outlet temperatures are low, the required compensation amount of hot air is larger, and the operating parameters are higher, preventing the temperature from rising too slowly, which could lead to low drying efficiency or clothes not being completely dried.

[0062] As an optional implementation of the above embodiments, the operating parameters include operating power; such as Figure 3 As shown, determining the operating parameters of the auxiliary heating device based on the exhaust temperature and / or the outlet temperature includes:

[0063] S311, if the exhaust temperature is greater than the first preset temperature and the outlet temperature is greater than the second preset temperature, then the operating power of the auxiliary heating device is determined to be the first power.

[0064] In this embodiment, the first preset temperature and the second preset temperature are determined based on the equipment's performance testing. When the exhaust temperature is greater than the first preset temperature and the outlet temperature is greater than the second preset temperature, the heat pump system heats the air inside the drum more quickly, and at this time, the operating power of the auxiliary heating device is the first power.

[0065] As an optional implementation of the above embodiments, such as Figure 3 As shown, determining the operating parameters of the auxiliary heating device based on the exhaust temperature and / or the outlet temperature further includes:

[0066] S312, if the exhaust temperature is less than the first preset temperature or the outlet temperature is less than the second preset temperature, then obtain the load parameters inside the drum;

[0067] S313, if the load parameter is greater than the preset parameter, then the operating power of the auxiliary heating device is determined to be the second power; wherein, the first power is less than the second power.

[0068] In this embodiment, when the exhaust temperature is lower than a first preset temperature or the outlet temperature is lower than a second preset temperature, the heating rate of the air inside the drum by the heat pump system is relatively slow. At this time, the load parameters are obtained. If the load parameters are greater than preset parameters, the current state parameters of the heat pump system are insufficient to dry the load or result in low drying efficiency. In this case, the operating power of the auxiliary heating device is determined to be a second power. If the second power is greater than the first power, the auxiliary heating device operates at a higher power to increase the heating rate of the air inside the drum, thereby satisfying the requirements for drying quality and drying efficiency.

[0069] As an optional implementation of the above embodiments, determining the operating parameters of the auxiliary heating device based on the exhaust temperature and / or the outlet temperature further includes:

[0070] If the load parameter is less than the preset parameter, then the operating power of the auxiliary heating device is determined to be the first power.

[0071] In this embodiment, when the exhaust temperature is lower than a first preset temperature or the outlet temperature is lower than a second preset temperature, the heating rate of the air inside the drum by the heat pump system is relatively slow. At this time, the load parameters are obtained. If the load parameters are lower than preset parameters, the current heat pump system status parameters are sufficient to dry the load, or the current drying efficiency meets the drying requirements. In this case, the operating power of the auxiliary heating device is determined to be the first power. The auxiliary heating device operates at a lower power to increase the heating rate of the air inside the drum, thus meeting the requirements for drying quality and efficiency.

[0072] In the above embodiments, the load parameters can be load humidity and load weight.

[0073] In this embodiment, both the load humidity and load weight decrease during the drying process. Therefore, in this embodiment, when the auxiliary heating device is running at the second power, if the load humidity or load weight decreases below the corresponding preset humidity or preset weight, the auxiliary heating device reduces to the first power and continues to operate, so that the temperature (and its rate of change) is adapted to the current condition of the load, thereby avoiding damage to the load (clothing).

[0074] As an optional implementation of the above embodiments, such as Figure 4 As shown, after the auxiliary heating device is started and operated according to the specified operating parameters, the drying control method includes:

[0075] S500, obtain the air inlet temperature of the air inlet of the roller;

[0076] S600, if the air inlet temperature reaches the third preset temperature, the auxiliary heating device is controlled to stop operating.

[0077] In this embodiment, after the auxiliary heating is activated, the inlet air temperature of the drum is obtained, which is the temperature of the gas after being heated by the heat pump system and the auxiliary heating device. Once this gas temperature reaches a third preset temperature, the air temperature inside the drum meets the drying quality and efficiency requirements of the load, at which point the auxiliary heating device is turned off. Because the gas in the drum is in an internal circulation state, the heat pump system can maintain the inlet air temperature above the third preset temperature (for a period of time) after the auxiliary heating device is turned off. By turning off the auxiliary heating device, the energy-saving effect of the equipment can be improved.

[0078] Furthermore, in some embodiments, after the auxiliary heating device is shut down and stops operating, if the inlet air temperature is lower than the fourth preset temperature (the fourth preset temperature is lower than the third preset temperature), the auxiliary heating device is restarted and runs again with the aforementioned operating parameters until the inlet air temperature reaches the third preset temperature. In this way, the auxiliary heating device can be started and stopped intermittently, which helps to save energy while maintaining drying efficiency. In some embodiments, the fourth preset temperature can be between 90% and 98% of the third preset temperature; it can be a factory setting or a percentage adjusted by the user according to their needs.

[0079] In some embodiments, the third preset temperature is determined after the device has undergone performance testing.

[0080] Reference Figure 5 This example illustrates a specific embodiment of the drying control method provided in this application. Controlled by a drying command, the heat pump system starts; the compressor's exhaust temperature and the condenser's outlet temperature are acquired; it is determined whether the exhaust temperature is greater than a first preset temperature and whether the outlet temperature is greater than a second preset temperature; if yes, the auxiliary heating device starts and operates at a first power; if no, the load weight is acquired; it is determined whether the load weight is less than a preset weight; if yes, the auxiliary heating device starts and operates at the first power; if no, the auxiliary heating device starts and operates at a second power; the second power is greater than the first power. After the auxiliary heating device starts, the inlet air temperature of the drum is acquired; until the inlet air temperature reaches a third preset temperature, the auxiliary heating device stops operating; if the inlet air temperature is less than the third preset temperature, the auxiliary heating device continues to operate and reacquires the inlet air temperature of the drum. Following the above steps, drying stops when the heat pump system finishes operating.

[0081] In the drying control method of the clothing processing equipment provided in this application embodiment, the auxiliary heating device can shorten the time for the heat pump system to reach the optimal working state; by monitoring the compressor exhaust, condenser outlet and drum inlet air temperatures, as well as the weight of the clothes, the auxiliary heating module can be intelligently controlled to start / stop and heating power, thereby achieving energy saving and improving the drying efficiency of the clothing processing equipment; the auxiliary heating device made of positive temperature coefficient material can heat up quickly and save electricity, and has an automatic constant temperature and overheat protection function, meeting the clothing processing equipment's requirements for precise temperature control and low energy consumption.
