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.

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.

[0047] 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.

[0048] In related technologies, heat pump drying equipment integrates the evaporator and condenser into a single unit to make reasonable use of the limited space between the clothes handling drum and the shell. However, within the limited space of the drying equipment, the volume of the two-unit assembly cannot be increased, resulting in the inability to effectively improve dehumidification efficiency and further enhance drying efficiency.

[0049] To address the above technical problems, this embodiment proposes a clothing processing device with a drying function. The clothing processing device includes:

[0050] A clothing processing drum, which is equipped with an air inlet and an air outlet;

[0051] An air duct assembly includes a main air duct and an auxiliary air duct, wherein the air inlets of the main air duct and the auxiliary air duct are connected to the air outlet, and the air outlets of the main air duct and the auxiliary air duct are connected to the air inlet.

[0052] 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.

[0053] The second dehumidification unit includes a condenser and an auxiliary fan, both of which are located in the auxiliary air duct.

[0054] The control device is configured to, during the clothes drying process, control the first dehumidifying unit and the second dehumidifying unit to dehumidify individually or simultaneously according to the clothes drying stage, or control the first dehumidifying unit and the second dehumidifying unit to dehumidify individually or simultaneously according to the humid and hot state of the clothes processing drum.

[0055] The clothing processing equipment in this embodiment controls the first dehumidification unit and the second dehumidification unit to dehumidify individually or simultaneously in different drying stages. This allows for dehumidification by the first dehumidification unit when the humidity inside the drum is low, and dehumidification by the first and second dehumidification units simultaneously when the humidity inside the drum is high. This solves the problem of high operating load on the heat pump components when the airflow humidity inside the clothing processing drum is high, thereby effectively improving dehumidification efficiency and shortening drying time.

[0056] 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 implementation methods and examples can be combined with each other.

[0057] 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:

[0058] 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.

[0059] In a preferred embodiment, such as Figure 1 As 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.

[0060] 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.

[0061] 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 and condenser in the main air duct.

[0062] 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.

[0063] The second dehumidification unit includes a condenser and an auxiliary fan 22. Both the condenser and the auxiliary fan 22 are located in the auxiliary air duct 32. The auxiliary fan 22 is located in the auxiliary air duct 32 to allow airflow to circulate in the circulating air path formed between the clothes processing drum 1 and the auxiliary air duct 32.

[0064] The control device is configured to, during the clothes drying process, control the first dehumidification unit and the second dehumidification unit to dehumidify individually or simultaneously according to the clothes drying stage, or control the first dehumidification unit and the second dehumidification unit to dehumidify individually or simultaneously according to the humid and hot state of the clothes processing drum.

[0065] Specifically, during the drying and heating stage, the control device controls the first dehumidification unit to dehumidify independently, that is, controls the heat pump assembly and the main fan 21 to start. When the humidity in the clothes processing drum 1 is low, the heat pump assembly heats the airflow in the main air duct 31 and then the main fan 21 sends the hot airflow into the clothes processing drum 1 to raise the temperature inside the clothes processing drum 1. As the temperature inside the clothes processing drum 1 rises, the hot airflow takes away moisture from the clothes to form a high temperature and high humidity airflow.

[0066] During the drying and dehumidification stage, the humidity inside the clothing processing drum 1 is relatively high. At this time, the control device controls the first dehumidification unit and the second dehumidification unit to dehumidify simultaneously, that is, controls the main fan 21 and the heat pump component to start, and controls the auxiliary fan 22 and the condenser to start, so as to increase the dehumidification capacity, reduce the operating load of the heat pump component, improve the dehumidification efficiency, and shorten the drying time.

[0067] In one embodiment, the condensation device is a water-cooled condensation device, which includes 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. The spray flow rate of the spray section 61 can be adjusted according to the water supply flow rate of the water supply section 62. When the spray section 61 is spraying, the water mist sprayed by the spray section 61 condenses the moisture in the auxiliary air duct. For example, the spray section 61 includes a plurality of spray holes, and the spray direction of the plurality of spray holes is towards the interior of the auxiliary air duct 32. Preferably, the plurality of 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.

[0068] The control device is also configured to control the spray flow rate of the spray section 61 according to the humidity and heat state of the clothes handling drum 1 during the dehumidification stage of the clothes drying process. For example, when the clothes handling drum 1 is in a high humidity and heat state, the control device controls the spray section 61 to spray at a first spray flow rate; when the clothes handling drum 1 is in a low humidity and heat state, the control device controls the spray section 61 to spray at a second spray flow rate, where the second spray flow rate is less than the first spray flow rate. The outlet air temperature of the clothes handling drum in the low humidity and heat state is greater than that in the high humidity and heat state. For example, the low humidity and heat state is defined as the outlet air temperature of the clothes handling drum 1 being greater than or equal to a first set temperature and less than a second set temperature, and the high humidity and heat state is defined as the outlet air temperature of the clothes handling drum 1 being less than the first set temperature.

[0069] In this embodiment, the spray section 61 is controlled to spray at a larger spray flow rate when the humidity inside the cylinder is high, so as to improve the dehumidification efficiency. When the humidity inside the cylinder is high, the spray section 61 is controlled to spray at a smaller spray flow rate, so as to reduce water loss while ensuring dehumidification efficiency.

[0070] In one example, the water supply unit 62 includes a first water supply path 621 and a second water supply path 622, both of which are connected to the spray unit 61. The water flow rate of the first water supply path 621 is greater than that of the second water supply path 622. The first water supply path 621 is equipped with a first water valve, which controls the opening and closing of the water flow path between the first water supply path 621 and the spray unit 61. The second water supply path 622 is equipped with a second water valve, which controls the opening and closing of the water flow path between the second water supply path 622 and the spray unit 61.

[0071] The control device is also configured to, during the dehumidification phase of the clothes drying process, control the first water supply path 621 or the second water supply path 622 to supply water to the spray section 61 based on the humid and hot state of the clothes handling drum 1. That is, when the clothes handling drum 1 is in a high humid and hot state, the control device controls the first water supply path 621 to supply water to the spray section 61, as per [reference needed]. Figure 2 The diagram shows the airflow and waterflow paths; when the clothes handling drum 1 is in a low humidity and heat state, the second water supply path 622 is controlled to supply water to the spray section 61, as shown in the diagram. Figure 3 The diagram shows the airflow path and waterflow path.

[0072] In other possible implementations, the water supply unit 62 includes a water supply path with an adjustable water valve. When the clothes handling drum 1 is in a high humidity and heat state, the control device controls the water valve to open to a larger degree, and when the clothes handling drum 1 is in a low humidity and heat state, the control device controls the water valve to open to a smaller degree.

[0073] In other possible implementations, the condensation device includes a first water-cooled condenser 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 includes a second water-cooled condenser 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.

[0074] In one alternative implementation, the heat pump assembly further includes a compressor 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 control device is also configured to control at least one of the following during the dehumidification phase of the clothes drying process: the operating frequency of the compressor, the speed of the main fan 21, and the speed of the auxiliary fan 22, based on the humid and hot state of the clothes handling drum 1.

[0075] Specifically, when the clothes processing drum 1 is in a high humidity and heat state, the control device controls the compressor to run at a first frequency to increase the dehumidification capacity and improve the dehumidification efficiency; when the clothes processing drum 1 is in a low humidity and heat state, the control device controls the compressor to run at a second frequency to reduce energy consumption, with the first frequency being greater than the second frequency.

[0076] And / or, when the clothes processing drum 1 is in a high humidity and heat state, the control device controls the main fan 21 to run at a first speed to increase the dehumidification capacity and improve the dehumidification efficiency; when the clothes processing drum 1 is in a low humidity and heat state, the control device controls the main fan 21 to run at a second speed to reduce energy consumption, wherein the first speed is greater than the second speed.

[0077] And / or, when the clothes processing drum 1 is in a high humidity and heat state, the control device controls the auxiliary fan 22 to run at a third speed to increase the dehumidification capacity and improve the dehumidification efficiency; when the clothes processing drum 1 is in a low humidity and heat state, the control device controls the auxiliary fan 22 to run at a fourth speed to reduce energy consumption, with the third speed > the fourth speed.

[0078] In one optional implementation, the control device further includes a first temperature detection device and a second temperature detection device. The first temperature detection device is disposed at the air inlet for detecting the inlet air temperature of the clothes processing drum 1, and the second temperature detection device is disposed at the air outlet for detecting the outlet air temperature of the clothes processing drum 1. The control device is configured to determine the clothes drying process based on the inlet air temperature and / or the outlet air temperature.

[0079] Specifically, when the inlet air temperature is lower than the third set temperature, the clothes processing drum 1 is determined to be in the drying and heating stage; when the inlet air temperature reaches the third set temperature and the outlet air temperature is lower than the second set temperature, the clothes processing drum 1 is determined to be in the drying and dehumidification stage; when the outlet air temperature is higher than the second set temperature, the clothes processing drum 1 is determined to enter the drying judgment stage. In the drying judgment stage, when the temperature difference between the inlet air temperature and the outlet air temperature reaches the drying judgment temperature difference a set number of times, the drying ends and the drying and cooling stage begins.

[0080] In a preferred embodiment, during the drying and cooling stage, the control device controls the heat pump assembly and the main fan 21 to shut down, and controls the condenser and the auxiliary fan 22 to start. The airflow in the auxiliary air duct 32 is condensed by the condenser 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 and the auxiliary fan 22 are shut down.

[0081] In this embodiment, during the drying and cooling stage, the temperature inside the drum is reduced by the auxiliary fan 22 and the condenser device, so as to avoid the residual heat of the condenser 5 being blown into the clothes processing drum 1 when the main fan 21 is started, thus reducing the cooling speed of the clothes processing drum 1.

[0082] This embodiment also proposes a drying method for a garment processing device. The drying method is applied to the garment processing device mentioned above, with reference to... Figure 4 The drying process flow chart shows the following steps:

[0083] S41. During the clothes drying process, determine the humid and hot state of the clothes drying stage or the clothes processing drum.

[0084] S42. Control the first dehumidification unit and the second dehumidification unit to dehumidify individually or simultaneously according to the clothes drying stage, or control the first dehumidification unit and the second dehumidification unit to dehumidify individually or simultaneously according to the humid and hot state of the clothes processing drum.

[0085] In one optional implementation, the first dehumidifying unit and the second dehumidifying unit are controlled to dehumidify individually or simultaneously according to the clothes drying stage, or the first dehumidifying unit and the second dehumidifying unit are controlled to dehumidify individually or simultaneously according to the humid and hot state of the clothes processing drum, including:

[0086] During the drying and heating stage, the first dehumidification unit is controlled to dehumidify independently;

[0087] During the dehumidification stage, the first dehumidification unit and the second dehumidification unit are controlled to dehumidify simultaneously.

[0088] When the first dehumidification unit is dehumidifying, the main fan 21 and the heat pump assembly are in the start-up state; when the second dehumidification unit is dehumidifying, the auxiliary fan 22 and the condenser are in the start-up state.

[0089] In one alternative implementation, the drying method further includes:

[0090] During the dehumidification stage, the spray flow rate of the spray section 61 is also controlled according to the humid and hot state of the clothing treatment drum 1.

[0091] In one optional implementation, controlling the spray flow rate of the spray section 61 according to the humid and hot state of the clothing treatment drum 1 includes:

[0092] When the garment processing drum 1 is in a high humidity and heat state, the spray section 61 is controlled to spray at a first spray flow rate.

[0093] When the garment processing drum 1 is in a low humidity and heat state, the spray section 61 is controlled to spray at a second spray flow rate, where the second spray flow rate is less than the first spray flow rate.

[0094] Specifically, the outlet air temperature of the clothing processing drum in the low humidity and heat state is greater than that in the high humidity and heat state. For example, the low humidity and heat state is defined as the outlet air temperature of the clothing processing drum 1 being greater than or equal to a first set temperature and less than a second set temperature, while the high humidity and heat state is defined as the outlet air temperature of the clothing processing drum 1 being less than the first set temperature.

[0095] In one alternative implementation, the drying method further includes:

[0096] When the clothes processing drum 1 is in a high humidity and heat state, the compressor is controlled to run at a first frequency; when the clothes processing drum 1 is in a low humidity and heat state, the compressor is controlled to run at a second frequency, and the first frequency is greater than the second frequency.
