[0050] Aiming at the technical problem that the internal space of the traditional heat pump drying equipment is limited and the volume of the two devices (evaporator and condenser) cannot be enlarged, resulting in limited dehumidification efficiency, this embodiment proposes a drying system, which includes:

[0051] An air duct assembly, comprising a main air duct and an auxiliary air duct, wherein the main air duct has a first air inlet end and a first air outlet end, and the air duct wall of the main air duct is provided with a connecting port, and the auxiliary air duct has a second air inlet end and a second air outlet end, and the second air outlet end is connected to the main air duct through the connecting port;

[0052] The main fan and the auxiliary fan are arranged in the main air duct and the auxiliary fan is arranged in the auxiliary air duct;

[0053] A heat pump assembly, comprising an evaporator and a condenser, wherein the condenser and the evaporator are arranged in a main air duct at intervals, the evaporator is arranged in a position corresponding to the connecting port in the main air duct, and the condenser is located downstream of the evaporator in the air flow direction;

[0054] A condensing device, arranged in the auxiliary air duct, for condensing the airflow in the auxiliary air duct;

[0055] The damper component is movably arranged on a side of the evaporator close to the auxiliary air duct. The damper component has a first position that allows the airflow in the auxiliary air duct to flow directly to the condenser without passing through the evaporator, and a second position that allows the airflow in the auxiliary air duct to flow to the condenser through the evaporator. The damper component can be controlled in the first position or the second position.

[0056] The present embodiment connects the auxiliary air duct with the main air duct, and the evaporator is arranged at a position corresponding to the connecting port, and a movable damper component is arranged on the side of the evaporator close to the auxiliary air duct, so as to control the position of the damper component in different drying stages of the drying process, so that the airflow in the auxiliary air duct is directly blown to the condenser without passing through the evaporator, thereby increasing the excess air volume of the condenser to achieve rapid temperature rise in the drum, or the airflow in the auxiliary air duct is made to flow to the condenser through the evaporator, thereby increasing the excess air volume of the evaporator and the condenser to achieve efficient initialization; and, the present embodiment further arranges a condensing device in the auxiliary air duct, and the start-up state of the condensing device can be controlled according to the wet and hot state in the clothing processing drum during the drying and dehumidification stage, so as to improve the dehumidification efficiency and shorten the drying time.

[0057] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and examples can be combined with each other if there is no conflict.

[0058] This embodiment proposes a drying system, such as Figure 1-Figure 3 As shown, the drying system includes an air duct assembly, a main fan 21, an auxiliary fan 22, a heat pump assembly, a condensing device 6 and a damper component 7, wherein:

[0059] The air duct assembly includes a main air duct 31 and an auxiliary air duct 32. The main air duct 31 has a first air inlet end and a first air outlet end 311, and the air duct wall of the main air duct 31 is provided with a connecting port 322. The auxiliary air duct 32 has a second air inlet end and a second air outlet end, and the second air outlet end is connected to the main air duct 31 through the connecting port 322. The auxiliary air duct 32 can be directly connected to the main air duct 31, and can also be indirectly connected to the main air duct 31 through a connecting air duct 321.

[0060] In the application scenario of the clothes processing device, a circulating air path is formed between the clothes processing drum 1 and the main air duct 31, and a circulating air path is formed between the clothes processing drum 1 and the auxiliary air duct 32. The main fan 21 is provided in the main air duct 31, and is used to make the air flow flow in the circulating air path formed between the clothes processing drum 1 and the main air duct 31, and the auxiliary fan 22 is provided in the auxiliary air duct 32, and is used to make the air flow flow in the circulating air path formed between the clothes processing drum 1 and the auxiliary air duct 32.

[0061] The heat pump assembly includes an evaporator 4 and a condenser 5. The condenser 5 and the evaporator 4 are arranged in the main air duct 31 at intervals. The condenser 5 is located downstream of the evaporator 4 in the air flow direction. The heat pump assembly also includes a compressor and a throttling device. The compressor, the condenser 5, the throttling device and the evaporator 4 are connected in sequence to form a refrigerant circulation flow path. During the clothes drying process, under the action of the main fan 21 and / or the auxiliary fan 22, the hot and humid airflow entering the main air duct 31 blows toward the evaporator 4, and forms dry cold air after the evaporator 4 absorbs heat. 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 clothes processing drum 1 to dry the clothes in the clothes processing drum 1. When the heat pump assembly is turned on, the compressor is in a starting state to allow the refrigerant to circulate in the refrigerant circulation flow path.

[0062] The condensing device 6 is arranged in the auxiliary air duct 32, and is used for condensing the airflow in the auxiliary air duct 32. During the drying process, when the auxiliary fan 22 is started, the airflow in the auxiliary air duct 32 can be condensed by the condensing device 6 and then blown to the evaporator 4, thereby reducing the load of the evaporator 4.

[0063] In one example, the condensing device 6 is a water condensing device, which includes a spraying part 61 and a water supply part 62. The spraying part 61 is arranged at the top of the auxiliary air duct 32, and the spraying direction of the spraying part 61 is toward the inside of the auxiliary air duct 32. The water supply part 62 is used to supply water to the spraying part 61. The water supply part 62 includes a water supply pipe and a water valve arranged on the water supply pipe. The water supply pipe is connected to the municipal water supply pipeline in the user's home. The water valve controls the water supply pipeline to supply water to the spraying part 61. Preferably, the multiple spray holes of the spraying part 61 are arranged along the width direction of the auxiliary air duct 32 to improve the uniformity of the distribution of water mist in the air flow, and at the same time, the dehumidification effect of the air flow in the auxiliary air duct 32 can be improved in the drying and dehumidification stage. When the condensing device 6 is turned on, the water valve is in an open state, so that the water in the water supply pipe continuously flows into the spraying part 61 and sprays out from the spray holes of the spraying part 61. In other achievable embodiments, the condensing device 6 may also be a water condensing tube wound around the inner wall or outer wall of the auxiliary air duct 32, or a plurality of water grooves opened on the inner wall or outer wall of the auxiliary air duct 32, which are not listed here one by one.

[0064] The damper component 7 is movably arranged on a side of the evaporator 4 close to the auxiliary air duct 32. The damper component 7 has a first position in which the airflow in the auxiliary air duct 32 flows directly to the condenser 5 without passing through the evaporator 4, and a second position in which the airflow in the auxiliary air duct 32 flows to the condenser 5 through the evaporator 4. The damper component 7 can be controlled in the first position or the second position.

[0065] Exemplarily, the damper component 7 includes a baffle and a motor for driving the baffle to move, the baffle includes a first end 71 and a second end 72 that are relatively arranged, the first end 71 is movably connected to a side of the evaporator 4 close to the auxiliary air duct 32, the second end 72 is connected to a side of the auxiliary air duct 32 away from the first air outlet end 311 when the damper component 7 is in the first position, and the second end 72 is connected to a side of the auxiliary air duct 32 close to the first air outlet end 311 when the damper component 7 is in the second position.

[0066] Preferably, the area of ​​the connecting port 322 is larger than the side area of ​​the evaporator 4 near the auxiliary air duct 32, so that the airflow in the auxiliary air duct 32 can flow to the condenser 5 or the evaporator 4 more smoothly, further ensuring the uniform distribution and efficient use of the air volume. Further preferably, the interval between the air inlet end of the evaporator and the end of the connecting port 322 near the main fan 21 is M1, and the interval between the air outlet end of the evaporator 4 and the end of the connecting port 322 away from the main fan 21 is M2, M1 = M2, thereby ensuring that when the damper component 7 is in the first position, the airflow in the auxiliary air duct 32 is blown directly to the condenser 5 without passing through the evaporator 4, and when the damper component 7 is in the second position, the airflow in the auxiliary air duct 32 is blown to the condenser 5 through the evaporator 4. In other achievable embodiments, similar technical effects can be obtained when the condenser is located at a position not opposite to the connecting port.

[0067] In the application scenario of clothing processing equipment, the drying system of this embodiment can realize the regulation of the position state of the damper component 7 according to the wet and hot state of the clothing processing drum 1 during the drying process, adjust the air duct connection state in real time, optimize the air flow path, and significantly improve the heating and dehumidification efficiency.

[0068] This embodiment also 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 4 As shown, the laundry processing device comprises a housing, a laundry processing drum 1, a control device and the drying system proposed above.

[0069] 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 provided at the drum opening of the clothes treatment drum 1, and the air inlet is arranged at the door seal. The air outlet is opened at the bottom of the clothes treatment drum 1, so that a long airflow path is formed between the air inlet and the air outlet, and the airflow can penetrate the clothes, thereby ensuring a uniform drying effect on the clothes.

[0070] The first air outlet end 311 is connected to the air inlet, and the first air inlet end and the second air inlet end are both connected to the air outlet, so that the hot and humid air flow in the clothing processing drum 1 can flow into the main air duct 31 and / or the auxiliary air duct 32 through the air outlet, and after being dehumidified and heated by the heat pump component in the main air duct 31, it enters the clothing processing drum 1 through the air inlet to dry the clothes.

[0071] In a preferred embodiment, there are two air outlets, and the first air inlet end and the second air inlet end are connected to the two air outlets in a one-to-one correspondence, so as to increase the air intake of the auxiliary air duct 32 and the main air duct 31. The two air outlets can be both arranged at the bottom of the laundry processing drum 1, or at different positions in the axial direction of the laundry processing drum 1, so as to deliver airflow to different positions in the laundry processing drum 1, and also improve the drying effect of the clothes.

[0072] The control device is configured to control the start-up of the main fan 21, the auxiliary fan 22 and the heat pump assembly during the clothes drying process, control the position state of the damper component 7 according to the clothes drying stage, and / or control the working state of the condensing device 6 according to the wet and hot state of the clothes processing drum 1 in the drying and dehumidification stage.

[0073] In the process of drying clothes, this embodiment controls the main fan 21 and the auxiliary fan 22 to start at the same time to increase the air intake of the clothes treatment drum 1, improve the heating and dehumidification efficiency, and shorten the drying time. At the same time, the position state of the damper component 7 is controlled according to the clothes drying stage to reasonably optimize the air flow path to achieve rapid heating and dehumidification. Alternatively, this embodiment also controls the working state of the condensing device 6 according to the wet and hot state of the clothes treatment drum 1 during the drying and dehumidification stage to further improve the dehumidification efficiency and shorten the drying time.

[0074] The clothes processing device of this embodiment further includes a temperature detection device, which is arranged in the clothes processing drum 1 and is used to detect the temperature inside the clothes processing drum 1. The control device is configured to control the heat pump component and the main fan 21 to be turned off during the drying and cooling stage, and to control the start-up state of the auxiliary fan 22 and the condensing device 6 according to the temperature inside the drum.

[0075] In this embodiment, after the drying and cooling stage, the heat pump assembly and the main fan 21 are controlled to be turned off to prevent the temperature in the drum from continuing to rise. At the same time, the temperature in the drum is further monitored, and the start-up state of the auxiliary fan 22 and the condensing device 6 is controlled according to the temperature in the drum to ensure that the temperature in the drum is reduced to a temperature that will not burn the user.

[0076] Specifically, when the temperature in the barrel is greater than the third set temperature, it means that the temperature in the barrel is relatively high. At this time, the condensing device 6 and the auxiliary fan 22 are controlled to be in the starting state, and the condensing device 6 cools the airflow in the auxiliary air duct 32. The cooled airflow enters the clothing treatment barrel 1 to achieve rapid cooling in the barrel. When the temperature in the barrel is less than or equal to the third set temperature, it means that the temperature in the barrel has reached a temperature that will not scald the user. At this time, the condensing device 6 and the auxiliary fan 22 are controlled to be closed, and the drying program ends. When the condensing device 6 includes a spray part 61 and a water supply part 62, the water mist sprayed by the spray part 61 can also enter the clothing treatment barrel 1 with the airflow in the auxiliary air duct 32, further improving the cooling effect of the temperature in the barrel.

[0077] Furthermore, before entering the drying process, the damper component 7 is also controlled to be in an initial position, such as the first position. Since the clothing drying process generally enters the drying and heating stage first, by first placing the damper component 7 in the first position, the movement of the damper component 7 can be reduced and power consumption can be reduced.

[0078] This embodiment proposes a drying method for a clothes processing device, and the drying method is applied to the clothes processing device with a drying function proposed above, referring to Figure 5 As shown in the drying flow chart, the drying method comprises the following steps:

[0079] S51, during the clothes drying process, controlling the heat pump assembly to start, controlling the main fan 21 to start at a first speed, and controlling the auxiliary fan 22 to start at a second speed;

[0080] S52, determining the clothes drying stage, and controlling the position state of the air door component 7 according to the clothes drying stage;

[0081] S53 . When the clothes drying stage is a drying and dehumidifying stage, the working state of the condensing device 6 is controlled according to the hot and humid state of the clothes processing tub 1 .

[0082] In the process of drying clothes, this embodiment controls the main fan 21 and the auxiliary fan 22 to start at the same time to increase the air intake of the clothes treatment drum 1, improve the heating and dehumidification efficiency, and shorten the drying time. At the same time, the position state of the damper component 7 is controlled according to the clothes drying stage to reasonably optimize the air flow path to achieve rapid heating and dehumidification. In the drying and dehumidification stage, this embodiment further controls the working state of the condensing device 6 according to the wet and hot state of the clothes treatment drum 1 to further improve the dehumidification efficiency and shorten the drying time.

[0083] Furthermore, the position state of the damper component 7 is controlled according to the stage of drying the clothes, including: in the drying and heating stage, the damper component 7 is controlled to be in the first position; in the drying and dehumidification stage, the damper component 7 is controlled to be in the second position.

[0084] In the drying and heating stage, the damper component 7 is controlled to be in the first position so that the airflow in the auxiliary air duct 32 can be blown directly to the condenser 5 without passing through the evaporator 4, increasing the air flow of the condenser 5 and causing the temperature in the laundry treatment drum 1 to rise rapidly. Figure 2 In the drying and dehumidification stage, the damper component 7 is controlled to be in the second position, so that the airflow in the auxiliary air duct 32 passes through the evaporator 4 and the condenser 5, increasing the excess air volume of the evaporator 4 and the condenser 5 and improving the dehumidification efficiency. Figure 3 The drying stage can be determined according to the air inlet temperature of the laundry processing drum 1, and can also be determined according to the drying time.

[0085] Furthermore, the working state of the condensing device 6 is controlled according to the wet and hot state of the clothes processing drum 1, including:

[0086] When the laundry treatment drum 1 is in a high-humidity and heat state, the condensing device 6 is controlled to be in a start-up state, so that the water mist sprayed by the condensing device 6 condenses the airflow in the auxiliary air duct 32, so as to reduce the load of the evaporator 4, and at the same time increase the excess air volume of the evaporator 4 and the condenser 5, improve the dehumidification efficiency, and shorten the drying time. When the laundry treatment drum 1 is in a low-humidity and heat state, the condensing device 6 is controlled to be in a closed state, which increases the excess air volume of the evaporator 4 and the condenser 5, ensures the dehumidification effect, and reduces energy consumption.

[0087] Among them, the high humidity and heat state of this embodiment refers to the state in which the humidity in the drum is high under a high temperature environment, and the low humidity and heat state refers to the state in which the humidity in the drum is low under a high temperature environment. Specifically, the air outlet temperature of the laundry processing drum in the low humidity and heat state is greater than the air outlet temperature of the laundry processing 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 laundry processing 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 laundry processing drum 1 is less than the first set temperature.

[0088] In an optional implementation, the drying method also includes: in the drying heating stage, controlling the speed of the main fan 21 to be lower than the first speed, and controlling the speed of the auxiliary fan 22 to be higher than the second speed, so as to increase the air flow directly blown to the condenser 5 without passing through the evaporator 4, thereby further accelerating the heating efficiency of the clothing processing drum 1.

[0089] And / or, in the drying and dehumidification stage, and the clothing treatment drum 1 is in a high humidity and heat state, the rotation speed of the auxiliary fan 22 is controlled to be higher than the second rotation speed to increase the air flow directly blown to the condenser 5 without passing through the evaporator 4, thereby further accelerating the dehumidification efficiency of the clothing treatment drum 1.

[0090] And / or, in the drying and dehumidification stage, when the clothes processing drum 1 is in a low-humidity and heat state, the auxiliary fan 22 is controlled to stop to reduce energy consumption.

[0091] In an optional implementation, the clothing drying method also includes: in the drying and cooling stage, controlling the heat pump assembly and the main fan 21 to be turned off; obtaining the drum temperature of the clothing processing drum 1, and when the drum temperature is greater than a third set temperature, controlling the auxiliary fan 22 and the condensing device 6 to be in a started state; when the drum temperature is less than or equal to the third set temperature, controlling the auxiliary fan 22 and the condensing device 6 to be turned off.

[0092] In the drying and cooling stage, the present embodiment controls the heat pump assembly and the main fan 21 to be turned off to prevent further temperature rise in the drum. At the same time, the temperature in the drum is further monitored, and the start-up state of the auxiliary fan 22 and the condensing device 6 is controlled according to the temperature in the drum to ensure that the temperature in the drum is reduced to a temperature that will not scald the user. Exemplarily, when the steam care duration reaches the set care duration, it is determined that the steam care end condition is met. In the drying and cooling stage, the damper component 7 can be in the first position or the second position, or in other positions other than the first position and the second position, preferably in the first position to shorten the flow path of the airflow entering the clothing treatment drum 1.

[0093] Specifically, when the temperature in the drum is greater than the second set temperature, it means that the temperature in the drum is relatively high. At this time, the condensing device 6 and the auxiliary fan 22 are controlled to be in the starting state, so that the air in the auxiliary air duct 32 passes through the condensing device 6 and cools down before entering the clothing processing drum 1, thereby achieving rapid cooling in the drum. Preferably, when the temperature in the drum is greater than the second set temperature, the speed of the auxiliary fan 22 is increased to be greater than the first initial speed to shorten the cooling time. When the temperature in the drum is less than or equal to the second set temperature, it means that the temperature in the drum has reached a temperature that will not scald the user. At this time, the condensing device 6 and the auxiliary fan 22 are controlled to be turned off, and the drying program ends.
