[0049] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0050] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply that they are different.

[0051] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0052] Because heat pump drying equipment only heats the airflow through the condenser and dehumidifies the airflow through the evaporator, the temperature rise inside the drum is slow and the dehumidification efficiency is low, resulting in a long drying time.

[0053] To address the above technical problems, this embodiment proposes a clothing processing device with a drying function. The clothing processing device includes:

[0054] A clothing processing drum, which is equipped with an air inlet and an air outlet;

[0055] The air duct assembly includes a main air duct and an auxiliary air duct, the air inlets of the main air duct and the auxiliary air duct are connected to the air outlets, and the air outlets of the main air duct and the auxiliary air duct are connected to the air inlets.

[0056] The first dehumidification unit includes a heat pump assembly and a main fan. The main fan is located in the main air duct. The heat pump assembly includes an evaporator and a condenser. Both the evaporator and the condenser are located in the main air duct, and in the airflow direction within the main air duct, the condenser is located downstream of the evaporator.

[0057] The second dehumidification unit includes a heating device, a condensing device, and an auxiliary fan. The heating device, condensing device, and auxiliary fan are all located in the auxiliary air duct, and in the direction of airflow in the auxiliary air duct, the heating device is located downstream of the condensing device.

[0058] The control device is configured to control the operating status of the first dehumidification unit and the second dehumidification unit according to the target temperature of the clothes processing drum during the clothes drying process.

[0059] This embodiment controls the states of the first and second dehumidification units according to the target temperature of the clothes processing drum during the drying process. This allows the drum temperature to be rapidly raised to the target drying temperature, increasing the drum heating rate. It also enables rapid condensation of moisture inside the drum, thereby improving dehumidification efficiency.

[0060] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following embodiments and examples can be combined with each other.

[0061] This embodiment proposes a clothing processing device with a drying function. This clothing processing device may have only a drying function, or it may have both drying and washing functions simultaneously. Figure 1 As shown, the garment processing equipment includes a housing, a garment processing drum 1, an air duct assembly, a first dehumidification unit, a second dehumidification unit, and a control device. Wherein:

[0062] A cavity is formed inside the housing, and a clothes processing drum 1 is housed within the cavity. The clothes processing drum 1 has an air inlet and an air outlet, the positions of which are not specifically defined. In one example, the opening of the clothes processing drum 1 is sealed, the air inlet is located at the seal, and the air outlet is located at the bottom of the drum. This creates a relatively long airflow path between the air inlet and the air outlet, allowing the airflow to penetrate the clothes and ensuring a uniform drying effect.

[0063] In a preferred embodiment, such as Figure 1As shown, there are two air inlets and two air outlets. The air inlets of the main air duct 31 and the auxiliary air duct 32 are connected to the two air outlets one by one, and the air outlets of the main air duct 31 and the auxiliary air duct 32 are connected to the two air inlets one by one, so as to increase the air intake and air output of the clothing processing drum 1.

[0064] The air duct assembly is disposed in the space between the housing and the clothing processing tube 1, preferably above the clothing processing tube 1. The air duct assembly includes a main air duct 31 and an auxiliary air duct 32. The air inlets of the main air duct 31 and the auxiliary air duct 32 are connected to the air outlets, and the air outlets of the main air duct 31 and the auxiliary air duct 32 are connected to the air inlets.

[0065] The first dehumidification unit includes a heat pump assembly and a main fan 21. The main fan 21 is located in the main air duct 31 and is used to circulate airflow in the circulating air path formed between the clothes handling drum 1 and the main air duct 31. The heat pump assembly includes an evaporator 4 and a condenser 5. Both the evaporator 4 and the condenser 5 are located within the main air duct 31, and in the airflow direction within the main air duct 31, the condenser 5 is located downstream of the evaporator 4. Preferably, the evaporator 4 and the condenser 5 are combined into a two-unit assembly to reduce the assembly difficulty of the evaporator 4 and the condenser 5 in the main air duct 31.

[0066] The first dehumidification unit also includes a compressor and a throttling device. The compressor, condenser 5, throttling device, and evaporator 4 are connected by refrigerant pipelines to form a refrigerant circulation loop. Under the action of the main fan 21, the hot and humid airflow entering the main air duct 31 from the first air outlet is blown toward the evaporator 4. After the evaporator 4 absorbs heat, it forms dry and cold air. The dry and cold air flows through the condenser 5 and is heated to form a high-temperature airflow. The high-temperature airflow finally enters the clothes processing drum 1 through the air inlet to dry the clothes in the clothes processing drum 1.

[0067] The second dehumidification unit includes a heating device 9, a condensing device 6, and an auxiliary fan 22. The heating device 9, the condensing device 6, and the auxiliary fan 22 are all located in the auxiliary air duct 32. The auxiliary fan 22 is used to make the airflow circulate in the circulating air path formed between the clothes processing drum 1 and the auxiliary air duct 32.

[0068] The control device is configured to control the operating status of the first and second dehumidification units based on the target temperature of the clothes handling drum 1 during the clothes drying process. During drying, the heat pump assembly, main fan 21, and auxiliary fan 22 are first activated. The heat pump assembly heats the airflow within the main air duct 31, and the heated airflow enters the clothes handling drum 1, raising its internal temperature. Simultaneously, the target temperature of the clothes handling drum 1 is detected. The target temperature can be at least one of the inlet and outlet air temperatures of the clothes handling drum 1. The target temperature reflects the humidity and heat state inside the drum. By controlling the first and second dehumidification units based on the humidity and heat state inside the drum, the heating and dehumidification efficiency inside the drum is improved, effectively shortening the drying time and enhancing the user experience.

[0069] In one alternative implementation, the heating device 9 includes an electric heater disposed within the auxiliary air duct 32. Exemplarily, the electric heater includes a resistance wire. In the direction of airflow within the auxiliary air duct 32, the heating device 9 is located downstream of the condensing device 6.

[0070] The condensation device 6 is a water-based condensation device, comprising a spray section 61 and a water supply section 62. The spray section 61 is disposed in the auxiliary air duct 32, and the water supply section 62 is connected to the municipal water supply pipeline for supplying water to the spray section 61. When the spray section 61 is in spray mode, the water mist sprayed by the spray section 61 condenses the moisture inside the auxiliary air duct 32. For example, the spray section 61 includes multiple spray holes, the spray direction of which faces the interior of the auxiliary air duct 32. Preferably, the multiple spray holes are disposed on the top wall of the auxiliary air duct 32 and arranged along the width direction of the auxiliary air duct 32 to increase the spray area.

[0071] In other possible implementations, the condensation device 6 includes a first water condensation pipe wound around the inner or outer wall of the auxiliary air duct 32, or includes multiple first water tanks opened on the inner or outer wall of the auxiliary air duct 32, and / or, the second condensation device 6 includes a second water condensation pipe wound around the inner or outer wall of the main air duct 31, or includes multiple second water tanks opened on the inner or outer wall of the main air duct 31, which will not be listed here.

[0072] In one optional implementation, the garment processing equipment further includes a first temperature detection device located at the air inlet for detecting the inlet air temperature of the garment processing drum 1. Preferably, the first temperature detection device is located at the air inlet corresponding to the air outlet of the main air duct 31. The control device is configured to control the heating device 9 and the condensing device 6 to alternately start based on the inlet air temperature during the garment drying process.

[0073] Specifically, during the drying process of the garment processing equipment, under the action of the main fan 21, the airflow in the garment processing drum 1 enters the main air duct 31 through the air outlet. The airflow in the main air duct 31 passes through the evaporator 4 and condenser 5 to form a high-temperature airflow, which is then sent back into the garment processing drum 1. Simultaneously, to increase the heating rate of the garment processing drum 1, the auxiliary fan 22 and the heating device 9 are also activated. Under the action of the auxiliary fan 22, the airflow entering the auxiliary air duct 32 from the air outlet is heated by the heating unit and then sent back into the garment processing drum 1, thereby accelerating the temperature rise inside the drum. (Refer to...) Figure 2 The diagram shows the water flow path and air flow path.

[0074] Furthermore, the inlet air temperature of the clothes processing drum 1 is monitored during the heating process; the higher the inlet air temperature, the higher the temperature inside the drum. If the inlet air temperature is lower than the third set temperature, it indicates that the drying airflow has not reached a temperature sufficient to vaporize the moisture on the clothes. In this case, the heating device 9 needs to be kept on to accelerate the heating inside the drum. When the inlet air temperature is greater than or equal to the third set temperature, the drying airflow can vaporize the moisture on the clothes, forming humid air. In this case, the heating device 9 can be turned off to reduce energy consumption. (Refer to...) Figure 3 The airflow path diagram is shown.

[0075] As the humidity inside the cylinder increases, the operating load of the heat pump components increases, and the dehumidification efficiency decreases. At this time, the heat pump components, main fan 21 and auxiliary fan 22 are kept on, and the condenser 6 is turned on to reduce the temperature inside the cylinder, so that the hot and humid air inside the cylinder reaches the dew point temperature. The high temperature and high humidity air condenses into water and is discharged outside the cylinder, thereby reducing the operating load of the heat pump components.

[0076] Because the temperature inside the drum drops rapidly after the condenser 6 is turned on, when the temperature inside the drum is lower than the third set temperature, the humidity inside the drum decreases and the condensation efficiency of the clothes decreases. At this time, the heating device 9 is turned on again and the condenser 6 is turned off to increase the heating rate inside the drum, so that the moisture in the clothes can be quickly vaporized into moisture, and the humidity inside the drum can be increased. This process is repeated until the clothes are dry.

[0077] In a preferred embodiment, during the condensation process of the condensation device 6, the spray flow rate of the spray device is controlled according to the inlet air temperature. The higher the inlet air temperature, the larger the spray flow rate, to further improve condensation efficiency. During the heating process of the heating device 9, the heating power of the heating device 9 is controlled according to the inlet air temperature. The higher the inlet air temperature, the lower the heating power of the heating device 9, to reduce heating energy consumption.

[0078] In one optional implementation, the garment processing equipment further includes a second temperature detection device located at the air outlet for detecting the outlet temperature of the garment processing drum 1. Preferably, the second temperature detection device is located at the air outlet corresponding to the air inlet of the main air duct 31.

[0079] The heat pump assembly also includes a compressor and a throttling device. The compressor is located outside the clothes handling drum 1, with its discharge end connected to the condenser 5 and its suction end connected to the evaporator 4. The throttling device is located in the refrigerant pipeline between the condenser 5 and the evaporator 4. The compressor, condenser 5, throttling device, and evaporator 4 are connected in sequence to form a refrigerant circulation loop. Under the action of the main fan 21, the airflow in the main air duct 31 absorbs heat through the evaporator 4 to form dry, cold air. This dry, cold air flows through the condenser 5 and is heated by the condenser 5 to form a high-temperature airflow. The high-temperature airflow finally enters the clothes handling drum 1 through the air inlet to dry the clothes in the drum 1. The operating frequency of the compressor in this embodiment is adjustable.

[0080] The control device is configured to control the operating frequency of the compressor based on the outlet air temperature during the drying and dehumidification stage.

[0081] Specifically, during the drying and dehumidification stage, the outlet air temperature is also monitored. The outlet air temperature reflects whether the clothes processing drum 1 is in a high-humidity / heat state or a low-humidity / heat state. If the outlet air temperature is lower than the first set temperature, it indicates that the drum is in a high-humidity / heat state, with high humidity. The frequency limit for alternating operation of the heating device 9 and the condensing device 6 is insufficient to meet the current humidity / heat load. In this case, the compressor can be controlled to operate at a higher first frequency. If the outlet air temperature is greater than or equal to the first set temperature but less than the second set temperature, it indicates that the drum is in a low-humidity / heat state, with low humidity. Alternating operation of the heating device 9 and the condensing device 6 can meet the current humidity / heat load. In this case, the compressor is controlled to operate at a lower second frequency. If the outlet air temperature is greater than or equal to the third set temperature, dehumidification is complete.

[0082] After the dehumidification stage, the drying stage begins. During the drying stage, drying ends when the temperature difference between the inlet and outlet air reaches the set number of times the drying temperature difference is reached, and the drying and cooling stage begins.

[0083] In a preferred embodiment, during the drying and cooling stage, the control device controls the heat pump assembly, heating device 9 and main fan 21 to shut down, and controls the condenser 6 and auxiliary fan 22 to remain running. The airflow in the auxiliary air duct 32 is condensed by the condenser 6 and its temperature is reduced. The cooled airflow enters the clothes processing drum 1 to reduce the temperature inside the drum. When the temperature inside the drum is reduced to a temperature that will not burn the user, the drying and cooling stage ends and the condenser 6 and auxiliary fan 22 are shut down.

[0084] In this embodiment, the heating device 9 is built into the auxiliary air duct 32. During the drying and heating stage, the hot air heated by the condenser 5 of the heat pump system is sent into the clothes processing drum 1 by the main fan 21. At the same time, the auxiliary fan 22 is turned on, activating the heating device 9 and the condenser 6 in the auxiliary air duct 32 to heat the air passing through the auxiliary air duct 32. The air heated by the heating device 9 in the auxiliary air duct 32 and the air heated by the condenser in the main air duct 31 are then sent into the clothes processing drum 1 by the auxiliary fan 22 and the main fan 21. Compared to heating the drum solely through the heat pump system, the simultaneous heating of the drum's ambient temperature by both air ducts shortens the heating stage time, thereby shortening the overall drying process time.

[0085] In this embodiment, the condenser 6 is also built into the auxiliary air duct 32. The condenser 6 can effectively cool the high-temperature environment inside the cylinder, and the high-temperature and high-humidity gas condenses into water when it reaches the dew point temperature and is discharged outside the cylinder. In the traditional dehumidification stage, relying solely on the condensation effect of the evaporator 4 in the main air duct 31 cannot quickly cool the environment inside the cylinder, which would increase the workload of the heat pump components and result in a long cooling time. By turning on the auxiliary fan 22 and the condenser 6, the air is condensed by the condenser 6 in the auxiliary air duct 32 and then sent into the cylinder by the auxiliary fan 22 to reduce the temperature of the environment inside the cylinder and achieve the dehumidification effect.

[0086] During the drying and heating stage, the main fan 21 is turned on, and air heated by the condenser 5 in the heat pump system is sent into the clothes processing drum 1 through the main air duct 31. Simultaneously, the auxiliary fan 22 is turned on, and air heated by the heating device 9 is sent into the clothes processing drum 1 through the auxiliary air duct 32, gradually increasing ventilation and heating inside the drum until the temperature reaches the clothes drying temperature. When the inlet air temperature of the clothes processing drum 1 reaches the third set temperature, the heating device 9 is turned off and the condenser 6 is turned on. Air processed by the condenser 6 is sent into the drum through the auxiliary air duct 32, lowering the drum temperature and increasing the relative humidity until the dew point temperature is reached. The high-temperature, high-humidity gas condenses into water and is discharged outside the drum. During dehumidification, the ambient temperature inside the drum decreases under the action of the condenser 6. A lower ambient temperature reduces the efficiency of water condensation from the clothes. When the inlet air temperature of the clothes processing drum 1 drops to the third set temperature, the heating device 9 is turned on and the condenser 6 is turned off to raise the ambient temperature inside the drum.

[0087] When the air inlet temperature reaches the third set temperature, the condenser 6 is turned on again and the heating device 9 is turned off. When the air inlet temperature of the clothes processing drum 1 is lower than the third set temperature, the ambient temperature inside the drum is low and the condensation efficiency of the clothes water is reduced. At this time, the heating device 9 is turned on and the condenser 6 is turned off to raise the temperature.

[0088] Furthermore, during the dehumidification stage, when the outlet air temperature of the clothes processing drum 1 is lower than the first set temperature, the humidity and heat load inside the drum is low. The compressor can be kept running at a low frequency by controlling the alternating start of the heating device 9 and the condensing device 6. When the outlet air temperature of the clothes processing drum 1 is greater than or equal to the first set temperature and less than the second set temperature, the humidity and heat load inside the drum is high. The frequency limit for alternating start of the heating device 9 and the spray unit can no longer meet the current humidity and heat load. At this time, the frequency of the variable frequency compressor should be appropriately increased to improve the dehumidification efficiency.

[0089] This process is repeated until the clothes are dry. In summary, the clothing processing equipment of this embodiment, through optimization of its structure and control methods, can effectively improve dehumidification efficiency and shorten drying time.

[0090] It should be noted that the first set temperature, the second set temperature, and the third set temperature can be a single temperature value or a temperature range. The first set temperature, the second set temperature, and the third set temperature can be flexibly set according to the actual situation.

[0091] This embodiment also proposes a drying method for a garment processing device. The drying method is applied to the garment processing device with drying function described above, referring to... Figure 4 The drying process flow chart shows the following steps:

[0092] S41. During the clothes drying process, obtain the temperature at the target position of the clothes processing drum 1;

[0093] S42. Control the working status of the first dehumidification unit and the second dehumidification unit according to the target location temperature;

[0094] The target location temperature includes at least one of the inlet air temperature and the outlet air temperature of the clothing processing drum 1.

[0095] In one alternative implementation, refer to Figure 5 The drying process flow chart, which controls the operating status of the first and second dehumidification units based on the target location temperature, includes the following steps:

[0096] S51. During the drying process, control the start of the main fan 21, auxiliary fan 22 and heat pump assembly;

[0097] S52. Obtain the air inlet temperature of the garment processing drum 1;
