[0048] In the related art, the heat pump drying device integrates the evaporator and the condenser into a two-device component to reasonably utilize the limited space between the clothing treatment drum and the shell. However, within the limited space of the drying device, the volume of the two-device component cannot be increased, resulting in the inability to effectively improve the dehumidification efficiency and the drying efficiency cannot be further improved.

[0049] In order to solve the above technical problems, this embodiment proposes a clothes processing device with a drying function, the clothes processing device comprising:

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

[0051] An air duct assembly, comprising a main air duct and an auxiliary air duct, wherein the air inlet ends of the main air duct and the auxiliary air duct are both connected to the air outlet, and the air outlet ends of the main air duct and the auxiliary air duct are both connected to the air inlet;

[0052] A first dehumidification unit, comprising a heat pump assembly and a main fan, the main fan being arranged in the main air duct, the heat pump assembly comprising an evaporator and a condenser, the evaporator and the condenser being arranged in the main air duct, and the condenser being located downstream of the evaporator in the air flow direction in the main air duct;

[0053] A second dehumidification unit includes a condensing device and an auxiliary fan, wherein the condensing device and the auxiliary fan are both arranged in the auxiliary air duct;

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

[0055] The clothing processing device of this embodiment controls the first dehumidification unit and the second dehumidification unit to dehumidify separately or simultaneously in different drying stages, so that dehumidification can be achieved through the first dehumidification unit when the humidity in the drum is low, and dehumidification can be achieved through the first dehumidification unit and the second dehumidification unit simultaneously when the humidity in the drum is high, thereby solving the problem of high operating load of the heat pump component when the humidity of the air flow in the clothing processing drum is high, thereby effectively improving the dehumidification efficiency and shortening the drying time.

[0056] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following implementation modes and examples may be combined with each other if there is no conflict.

[0057] This embodiment provides a clothes processing device with a drying function. The clothes processing device of this embodiment may have only a drying function or may have both a drying function and a washing function. Figure 1 As shown, the clothes processing device includes a housing, a clothes processing drum 1, an air duct assembly, a first dehumidification unit, a second dehumidification unit and a control device. Among them:

[0058] A shell cavity is formed in the shell, and a clothes treatment drum 1 is arranged in the shell cavity. The clothes treatment drum 1 is provided with an air inlet and an air outlet, and the arrangement positions of the air inlet and the air outlet are not clearly defined. In one example, a door seal is arranged at the drum opening of the clothes treatment drum 1, the air inlet is arranged at the door seal, and the air outlet is arranged at the drum bottom of the clothes treatment drum 1, so that a long air flow path is formed between the air inlet and the air outlet, and the air flow can penetrate the clothes, thereby ensuring a uniform drying effect on the clothes.

[0059] In a preferred embodiment, Figure 1 As shown, there are two air inlets and two air outlets respectively, and the air inlet ends 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 outlet ends of the main air duct 31 and the auxiliary air duct 32 are connected to the two air inlets one by one to increase the air intake and air outlet of the clothing processing drum 1.

[0060] The air duct assembly is arranged in the space between the housing and the laundry treatment drum 1, preferably arranged above the laundry treatment drum 1. The air duct assembly includes a main air duct 31 and an auxiliary air duct 32, the air inlet ends of the main air duct 31 and the auxiliary air duct 32 are both connected to the air outlet, and the air outlet ends of the main air duct 31 and the auxiliary air duct 32 are both connected to the air inlet.

[0061] The first dehumidification unit includes a heat pump assembly and a main fan 21, the main fan 21 is arranged in the main air duct 31, and is used to make the air flow circulate in the circulating air path formed between the clothes processing drum 1 and the main air duct 31. The heat pump assembly includes an evaporator 4 and a condenser 5, and the evaporator 4 and the condenser 5 are both arranged in the main air duct 31, and in the air flow direction in 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-device assembly to reduce the difficulty of assembling the evaporator and the condenser in the main air duct.

[0062] The first dehumidification unit also includes a compressor and a throttling device, wherein the compressor, the condenser 5, the throttling device and the evaporator 4 are connected by a refrigerant pipeline 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, and forms dry cold air after absorbing heat in the evaporator 4. The dry cold air flows through the condenser 5 to be heated to form a high-temperature airflow, and the high-temperature airflow finally enters the clothing treatment drum 1 through the air inlet to dry the clothes in the clothing treatment drum 1.

[0063] The second dehumidification unit includes a condensing device and an auxiliary fan 22 , both of which are arranged in the auxiliary air duct 32 . The auxiliary fan 22 is arranged in the auxiliary air duct 32 to allow the air flow to flow in the circulating air path formed between the clothing 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 separately or simultaneously according to the clothes drying stage, or control the first dehumidification unit and the second dehumidification unit to dehumidify separately or simultaneously according to the hot and humid state of the clothes processing drum.

[0065] Specifically, in the drying and heating stage, the control device controls the first dehumidification unit to dehumidify alone, that is, controls the heat pump assembly and the main fan 21 to start, so that when the humidity in the clothing treatment drum 1 is low, the heat pump assembly heats the airflow in the main air duct 31 and sends the hot air flow into the clothing treatment drum 1 through the main fan 21 to increase the temperature in the clothing treatment drum 1. As the temperature in the clothing treatment drum 1 increases, the hot air flow takes moisture from the clothes to form a high-temperature and high-humidity airflow.

[0066] During the drying and dehumidification stage, the humidity in the clothing treatment drum 1 is relatively high. At this time, the control device controls the first dehumidification unit and the second dehumidification unit to dehumidify at the same time, that is, controls the main fan 21 and the heat pump component to start, and controls the auxiliary fan 22 and the condensing device to start, so as to increase the dehumidification amount, reduce the working 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 condensation device, which includes a spray part 61 and a water supply part 62. The spray part 61 is arranged in the auxiliary air duct 32. The water supply part 62 is connected to the municipal water supply pipeline for supplying water to the spray part 61. The spray flow rate of the spray part 61 can be adjusted according to the water supply flow rate of the water supply part 62. When the spray part 61 is in the spraying state, the water mist sprayed by the spray part 61 condenses the moisture in the auxiliary air duct. Exemplarily, the spray part 61 includes a plurality of spray holes, and the spraying direction of the plurality of spray holes is toward the inside of the auxiliary air duct 32. Preferably, the plurality of spray holes are arranged 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 spraying area.

[0068] The control device is also configured to control the spray flow rate of the spray part 61 according to the humidity and heat state of the clothing treatment drum 1 in the dehumidification stage of the clothing drying process. For example, when the clothing treatment drum 1 is in a high humidity and heat state, the control device controls the spray part 61 to spray at a first spray flow rate; when the clothing treatment drum 1 is in a low humidity and heat state, the spray part 61 is controlled to spray at a second spray flow rate, and the second spray flow rate is less than the first spray flow rate. In the low humidity and heat state, the air outlet temperature of the clothing treatment drum is greater than the air outlet temperature of the clothing treatment drum in the high humidity and heat state. Exemplarily, the low humidity and heat state is a state in which the air outlet temperature of the clothing treatment drum 1 is greater than or equal to the first set temperature and less than the second set temperature, and the high humidity and heat state is a state in which the air outlet temperature of the clothing treatment drum 1 is less than the first set temperature.

[0069] This embodiment improves the dehumidification efficiency by controlling the spray part 61 to spray at a larger spray flow rate when the humidity in the barrel is high, and controls the spray part 61 to spray at a smaller spray flow rate when the humidity in the barrel is high, thereby reducing water loss while ensuring the dehumidification efficiency.

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

[0071] The control device is further configured to control the first water supply flow path 621 or the second water supply flow path 622 to supply water to the spray part 61 according to the hot and humid state of the laundry treatment drum 1 during the dehumidification stage of the laundry drying process. That is, when the laundry treatment drum 1 is in a high hot and humid state, the control device controls the first water supply flow path 621 to supply water to the spray part 61. Figure 2 When the laundry treatment drum 1 is in a low heat and humidity state, the second water supply flow path 622 is controlled to supply water to the spray portion 61, referring to Figure 3 The air flow path and water flow path diagram are shown.

[0072] In other possible implementations, the water supply unit 62 includes a water supply path, which is provided with a water valve with adjustable opening. When the clothing treatment drum 1 is in a high humidity and heat state, the control device controls the water valve to open with a larger opening. When the clothing treatment drum 1 is in a low humidity and heat state, the control device controls the water valve to open with a smaller opening.

[0073] In other possible implementations, the condensing device includes a first water condensing tube wound around the inner wall or outer wall of the auxiliary air duct 32, or includes a plurality of first water grooves opened on the inner wall or outer wall of the auxiliary air duct 32, and / or the second condensing device includes a second water condensing tube wound around the inner wall or outer wall of the main air duct 31, or includes a plurality of second water grooves opened on the inner wall or outer wall of the main air duct 31, which are not listed one by one here.

[0074] In an optional implementation, the heat pump assembly further includes a compressor, which is disposed outside the laundry treatment tub 1, wherein the exhaust end of the compressor is connected to the condenser 5, and the suction end of the compressor is connected to the evaporator 4. The control device is further configured to control at least one of the operating frequency of the compressor, the rotation speed of the main fan 21, and the rotation speed of the auxiliary fan 22 according to the hot and humid state of the laundry treatment tub 1 during the dehumidification phase of the laundry drying process.

[0075] Specifically, when the laundry treatment drum 1 is in a high humidity and heat state, the control device controls the compressor to operate at a first frequency to increase the dehumidification amount and improve the dehumidification efficiency; when the laundry treatment drum 1 is in a low humidity and heat state, the control device controls the compressor to operate at a second frequency to reduce energy consumption, and the first frequency>the second frequency;

[0076] And / or, when the laundry treatment drum 1 is in a high humidity and heat state, the control device controls the main fan 21 to operate at a first speed to increase the dehumidification amount and improve the dehumidification efficiency; when the laundry treatment drum 1 is in a low humidity and heat state, the control device controls the main fan 21 to operate at a second speed to reduce energy consumption, and the first speed>the second speed;

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

[0078] In an optional implementation, the control device further includes a first temperature detection device and a second temperature detection device, wherein the first temperature detection device is disposed at the air inlet for detecting the air inlet temperature of the laundry treatment drum 1, and the second temperature detection device is disposed at the air outlet for detecting the air outlet temperature of the laundry treatment drum 1. The control device is configured to determine the laundry drying process according to the air inlet temperature and / or the air outlet temperature.

[0079] Specifically, when the inlet air temperature is less than the third set temperature, it is determined that the laundry processing drum 1 is in the drying and heating stage; when the inlet air temperature reaches the third set temperature and the outlet air temperature is less than the second set temperature, it is determined that the laundry processing drum 1 is in the drying and dehumidification stage; when the outlet air temperature is greater than the second set temperature, it is determined that the laundry processing drum 1 enters 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 for a set number of times, the drying ends and enters the drying and cooling stage.

[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, controls the condensing device and the auxiliary fan 22 to start, and the airflow in the auxiliary air duct 32 is condensed by the condensing device and the temperature is reduced. The cooled airflow flows into the clothing processing drum 1 to reduce the temperature in the drum. When the temperature in the drum is reduced to a temperature that will not scald the user, the drying and cooling stage ends, and the condensing device and the auxiliary fan 22 are turned off.

[0081] In this embodiment, the temperature in the drum is cooled by the auxiliary fan 22 and the condensing device during the drying and cooling stage, so as to avoid blowing the waste heat of the condenser 5 into the clothes processing drum 1 when the main fan 21 is started, thereby reducing the cooling speed of the clothes processing drum 1.

[0082] This embodiment also proposes a drying method for a clothes processing device, and the drying method is applied to the clothes processing device proposed above, referring to Figure 4 The drying process flow chart of the present invention comprises the following steps:

[0085] In an optional implementation, controlling the first dehumidification unit and the second dehumidification unit to dehumidify individually or simultaneously according to the clothes drying stage, or controlling the first dehumidification unit and the second dehumidification unit to dehumidify individually or simultaneously according to the hot and humid state of the clothes processing drum, includes:

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

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

[0088] Wherein, when the first dehumidification unit is dehumidifying, the main fan 21 and the heat pump assembly are in the starting state; when the second dehumidification unit is dehumidifying, the auxiliary fan 22 and the condensing device are in the starting state.

[0089] In an optional implementation, the drying method further comprises:

[0090] In the dehumidification stage, the spray flow rate of the spray part 61 is also controlled according to the hot and humid state of the laundry treatment tub 1 .

[0091] In an optional implementation, the spray flow rate of the spray part 61 is controlled according to the hot and humid state of the clothes processing drum 1, including:

[0092] When the laundry treatment drum 1 is in a high-humidity and high-heat state, the spraying part 61 is controlled to spray at a first spraying flow rate;

[0093] When the laundry treatment tub 1 is in a low-humidity and low-heat state, the spraying part 61 is controlled to spray at a second spraying flow rate, and the second spraying flow rate is less than the first spraying flow rate;
