For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0051] In the related art, the heat pump drying equipment reasonably utilizes the limited space between the clothing processing drum and the shell by integrating the evaporator and the condenser into a two-device component. However, due to the limited space of the drying equipment, the volume of the two-device component cannot be increased, resulting in the dehumidification efficiency cannot be effectively improved, and the drying efficiency cannot be further improved.

[0052] In order to solve the above technical problems, this embodiment proposes a drying system, which includes:

[0053] An air duct assembly includes a main air duct, an auxiliary air duct and a connecting air duct, wherein the main air duct has a first air inlet end and a first air outlet end, the auxiliary air duct has a second air inlet end and a second air outlet end, the air duct wall of the main air duct has a first connecting port, the air duct wall of the auxiliary air duct has a second connecting port, and the connecting air duct connects the first connecting port and the second connecting port;

[0054] 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;

[0055] A heat pump assembly, comprising an evaporator and a condenser, wherein the evaporator and the condenser are both arranged in the main air duct, and the condenser is located downstream of the evaporator in the air flow direction;

[0056] A condensing device, which is arranged in the auxiliary air duct and is used to condense the airflow in the auxiliary air duct;

[0057] The damper component is movably arranged to have a first position for connecting the airflow path between the main air duct and the auxiliary air duct, and a second position for blocking the airflow path between the main air duct and the auxiliary air duct. The damper component can be controlled in the first position or the second position.

[0058] In this embodiment, a connecting air duct is added between the main air duct provided with the two-device assembly and the auxiliary air duct provided with the condensing device, and a movable air door component is further provided, so that the air door component can be controlled to be in the first position to connect the main air duct and the auxiliary air duct under the high humidity and heat state in the drying and dehumidification stage, and the auxiliary fan and the condensing device are further controlled to start so that the airflow in the clothes processing drum and the main air duct can enter the auxiliary air duct and be dehumidified in the auxiliary air duct by the condensing device, thereby increasing the dehumidification amount in the drying process and improving the dehumidification efficiency;

[0059] This embodiment can also control the damper component to be in the second position to block the passages of the main air duct and the auxiliary air duct in the low-humidity and heat state of the drying temperature rise stage and the drying dehumidification stage, and control the auxiliary fan and the condensing device to be turned off to reduce energy consumption and reduce drying noise;

[0060] This embodiment can also control the damper component to be in the second position to block the passages of the main air duct and the auxiliary air duct during the drying and cooling stage, and control the fan and the condensing device to start to accelerate the cooling speed in the drum.

[0061] 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.

[0062] This embodiment proposes a drying system, such as Figure 1 As shown, the drying system includes an air duct assembly, a main fan 21, an auxiliary fan 22, a heat pump assembly and a condensing device 6, wherein:

[0063] The air duct assembly includes a main air duct 31, an auxiliary air duct 32 and a connecting air duct 33. 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 first connecting port 312. The auxiliary air duct 32 has a second air inlet end and a second air outlet end 321, and the air duct wall of the auxiliary air duct 32 is provided with a second connecting port 322. The connecting air duct 33 connects the first connecting port 312 with the second connecting port 322. In the application scenario of the clothing processing device, a circulating air path is formed between the clothing processing drum 1 and the main air duct 31, and a circulating air path is formed between the clothing 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 circulate in the circulating air path formed between the clothing processing drum 1 and the main air duct 31. The auxiliary fan 22 is provided in the auxiliary air duct 32, and is used to make the air flow circulate in the circulating air path formed between the clothing processing drum 1 and the auxiliary air duct 32.

[0064] In one example, the main air duct 31, the auxiliary air duct 32 and the connecting air duct 33 are all arranged at the top of the clothing processing drum 1, and the main air duct 31 and the auxiliary air duct 32 are symmetrically arranged about the connecting air duct 33 to improve the reliability of the connection between the main air duct 31, the auxiliary air duct 32 and the connecting air duct 33.

[0065] The heat pump assembly includes an evaporator 4 and a condenser 5, both of which are arranged in the main air duct 31, and the condenser 5 is located downstream of the evaporator 4 in the air flow direction. The evaporator 4 and the condenser 5 can be arranged in the main air duct 31 independently of each other, or the evaporator 4 and the condenser 5 can be integrated into a one-two-device structure and arranged in the main air duct 31 as a whole.

[0066] The heat pump assembly also includes a compressor and a throttling device. The compressor, condenser 5, throttling device and 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, the hot and humid airflow entering the main air duct 31 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 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 the starting state to allow the refrigerant to circulate in the refrigerant circulation flow path.

[0067] The condensing device 6 is arranged in the auxiliary air duct 32, and is used to condense the airflow in the auxiliary air duct 32. During the drying process, when the auxiliary fan 22 and the condensing device 6 are started, the airflow in the auxiliary air duct 32 can be condensed by the condensing device 6 and then directly blown into the clothes processing drum 1 through the auxiliary air duct 32, thereby reducing the temperature and humidity of the airflow entering the clothes processing drum 1, adjusting the temperature in the drum and the relative humidity in the drum, and ensuring that the two devices do not operate under high humidity conditions. In addition, after the drying is completed, the condensing device 6 can also reduce the temperature of the airflow in the auxiliary air duct 32 and send it into the clothes processing drum 1 to quickly reduce the temperature in the drum, so as to prevent the user from being scalded by the high-temperature airflow in the drum after opening the door of the clothes processing device.

[0068] The damper component 7 is movably arranged, and has a first position for connecting the airflow passage between the main air duct 31 and the auxiliary air duct 32, and a second position for blocking the airflow passage between the main air duct 31 and the auxiliary air duct 32. The damper component 7 can be controlled in the first position or the second position. The damper component 7 can be arranged at any position of the connecting air duct 33. In a preferred embodiment, the damper component 7 is arranged at one end of the connecting air duct 33 close to the auxiliary air duct 32 or at one end of the connecting air duct 33 close to the main air duct 31.

[0069] Exemplarily, the damper component 7 is arranged on the connecting air duct 33, which includes a baffle and a motor that drives the baffle to move, the baffle includes a first end 71 and a second end 72 that are relatively arranged, the connecting air duct 33 includes a first side wall and a second side wall that are relatively arranged, the first end 71 is movably connected to the first side wall, the second end 72 is separated from the second side wall when the damper component 7 is in the first position, and the air flow path between the main air duct 31 and the auxiliary air duct 32 is connected, and the second end 72 is sealedly connected to the second side wall when the damper component 7 is in the second position, and the air flow path between the main air duct 31 and the auxiliary air duct 32 is blocked.

[0070] In this embodiment, the position of the damper component 7 can be adjusted during the clothes drying process to flexibly adjust the air flow path between the auxiliary air duct 32, the connecting air duct 33 and the main air duct 31, thereby improving the dehumidification efficiency in the dehumidification stage, shortening the drying time, and accelerating the cooling effect in the cooling stage.

[0071] In an optional implementation, in the direction of air flow in the main air duct 31, the evaporator 4 is located downstream of the first connecting port 312. On the one hand, this prevents the evaporator 4 and the condenser 5 from affecting the excess air volume between the connecting air duct 33 and the main air duct 31; on the other hand, it prevents the air flow in the main air duct 31 from entering the connecting air duct 33 after being condensed by the evaporator 4 or heated by the condenser 5, thereby reducing the condensation effect of the condensing device 6.

[0072] And / or, in the direction of air flow in the auxiliary air duct 32, the condensing device 6 is located downstream of the second connecting port 322, so as to prevent the air flow from the main air duct 31 from entering the clothing processing drum 1 through the auxiliary air duct 32 without being condensed by the condensing device 6, thereby reducing the dehumidification effect.

[0073] In an optional implementation, the condensation device 6 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, and the spraying direction of the spray part 61 is toward the inside of the auxiliary air duct 32. The water supply part 62 is connected to the spray part 61 for supplying water to the spray part 61.

[0074] The water supply unit 62 includes a water supply pipe and a water valve provided 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 spray unit 61. In the drying and dehumidification stage, the water mist sprayed by the spray unit 61 can condense the airflow in the auxiliary air duct 32, thereby reducing the humidity of the airflow in the auxiliary air duct 32. In the drying and cooling stage, the water mist sprayed by the spray unit 61 can also enter the clothes processing drum 1 along with the airflow in the auxiliary air duct 32, further increasing the cooling speed.

[0075] Preferably, the multiple spray holes of the spray part 61 are arranged along the width direction of the auxiliary air duct 32 to improve the uniformity of the distribution of the water mist in the airflow, and at the same time, the cooling and dehumidification effect of the airflow in the auxiliary air duct 32 can be improved in the drying and dehumidification stage and the drying and cooling stage. When the condensing device 6 is turned on, the water valve is opened, so that the water in the water supply pipe continuously flows into the spray part 61 and is sprayed out from the spray holes of the spray part 61.

[0076] In other achievable embodiments, the condensing device 6 may include a water condensing tube wound around the inner wall or outer wall of the auxiliary air duct 32, or include 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.

[0077] This embodiment also proposes a clothes processing device with a drying function, such as Figure 5 As shown, the clothes processing device of this embodiment may have only a drying function, or may have both a drying function and a washing function. The clothes processing device includes a housing, a clothes processing drum 1, a control device, and the drying system proposed above. Among them:

[0078] A shell cavity is formed in the shell, and a clothing processing drum 1 is arranged in the shell cavity. The clothing processing drum 1 is provided with an air inlet and an air outlet. The first air outlet end 311 and the second air outlet end 321 are both 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 humid and hot 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 first air inlet to dry the clothes.

[0079] The positions of the air inlet and the air outlet are not clearly defined. In one example, a door seal is provided at the opening of the laundry treatment drum 1, and the air inlet is provided at the door seal. The air outlet is provided at the bottom of the laundry 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.

[0080] In a preferred embodiment, there are two air inlets and two air outlets respectively, the first air inlet end and the second air inlet end are connected to the two air outlets one-to-one respectively, and the first air outlet end 311 and the second air outlet end 321 are connected to the two air inlets one-to-one respectively, so as to increase the air intake volume of the auxiliary air duct 32 and the main air duct 31.

[0081] The control device is configured to control the start-up state of the auxiliary fan 22 and the condensing device 6 and the position state of the damper component 7 according to the clothes drying stage or the wet and hot state of the clothes processing drum during the clothes drying process.

[0082] This embodiment adjusts the auxiliary fan 22, the condensing device 6 and the damper component 7 according to the clothing processing stage, thereby realizing flexible adjustment of the air flow path between the auxiliary air duct 32, the connecting air duct 33 and the main air duct 31 according to the temperature and humidity conditions in the drum, so as to further improve the dehumidification efficiency and shorten the drying time.

[0083] In actual applications, when the damper component is in the first position, the control device can control the opening and closing status and / or wind speed of the main fan and the auxiliary fan to enable the airflow in the main fan to enter the auxiliary air duct. The specific implementation method is not specifically limited here.

[0084] In an optional implementation, the clothing processing equipment also includes a first temperature detection device and a second temperature detection device. The first temperature detection device is arranged at the first air inlet, and is used to detect the inlet air temperature of the clothing processing drum 1. The second temperature detection device is arranged at the first air outlet, and is used to detect the outlet air temperature of the clothing processing drum 1. During the drying process, the inlet air temperature and / or the outlet air temperature of the clothing processing drum 1 are monitored to determine the drying stage of the clothes and the wet and hot state in the drum, thereby realizing the regulation of the drying process.

[0085] The drying process of the clothes processing device of this embodiment is described in detail below.

[0086] The clothes drying process includes a drying heating stage, a drying dehumidification stage and a drying cooling stage which are executed in sequence. In the drying heating stage, the control device first controls the main fan 21 and the heat pump assembly to start, and the air flow circulates between the clothes processing drum 1 and the main air duct 31. The auxiliary fan 22 and the water-cooled condensing device are in a closed state. At this time, the damper component 7 is controlled to be in the second position to prevent the air flow in the main fan 21 from entering the clothes processing drum 1 through the connecting air duct 33 and the auxiliary air duct 32 without being dehumidified and heated by the heat pump assembly, thereby reducing the heating effect. Figure 2 The airflow diagram is shown.

[0087] When the air inlet temperature of the clothes processing drum 1 reaches the third set temperature at which the drying temperature rising stage ends, the drying temperature rising stage ends and the drying and dehumidifying stage begins.

[0088] In the drying and dehumidification stage, when the drum is in a high humidity and heat state, the humidity in the drum is high, the load on the evaporator 4 is large, and the dehumidification efficiency is low. At this time, the condensing device 6 is controlled to start, and the auxiliary fan 22 is controlled to start to allow the air flow in the drum to enter the auxiliary air duct 32 and be cooled and dehumidified by the condensing device 6 before being directly passed into the clothing processing drum 1, thereby reducing the humidity in the drum, reducing the load on the evaporator 4, and thus improving the dehumidification efficiency.

[0089] Under high humidity and heat conditions, the damper component 7 can be controlled to the first position, at which time the airflow in the auxiliary air duct 32 is connected to the airflow in the main air duct 31, and part of the airflow in the auxiliary air duct 32 can enter the main air duct 31 through the connecting air duct 33 to increase the excess air volume of the evaporator 4 and improve the dehumidification efficiency of the evaporator 4, or part of the airflow in the main air duct 31 can enter the auxiliary air duct 32 through the connecting air duct 33 to increase the excess air volume of the condensing device 6 and improve the dehumidification efficiency of the condensing device 6, refer to Figure 3 The airflow path diagram shown. The airflow direction between the auxiliary air duct 32 and the main air duct 31 can be determined according to the rotation speeds of the main fan 21 and the auxiliary fan 22. For example, when the rotation speed of the main fan 21 is greater than that of the auxiliary fan 22, the airflow in the main fan 21 enters the auxiliary air duct 32 through the connecting air duct 33. When the rotation speed of the auxiliary fan 22 is greater than that of the main fan 21, the airflow in the auxiliary air duct 32 enters the main air duct 31 through the connecting air duct 33. The flow path of the airflow between the main air duct 31 and the auxiliary air duct 32 can flexibly adjust the wind speeds of the main fan 21 and the auxiliary fan 22 according to demand, which is not specifically limited here.

[0090] In other feasible embodiments, under high humidity and heat conditions, the airflow in the auxiliary air duct 32 is independent of the airflow in the main air duct 31 , that is, the damper component 7 can be controlled to the second position, at which time the airflow between the auxiliary air duct 32 and the main air duct 31 does not flow.

[0091] When the cylinder is in a low-humidity and heat state, the humidity in the cylinder is low, and the dehumidification effect can be achieved by using only the evaporator 4. At this time, the auxiliary fan 22 and the condensing device 6 are controlled to be closed to reduce energy consumption. At this time, the damper component 7 can be further controlled to be in the second position to prevent the airflow in the main air duct 31 from entering the auxiliary air duct 32 through the connecting air duct 33 without dehumidification, thereby reducing the dehumidification effect. Figure 2 Airflow diagram.

[0092] The air outlet temperature of the laundry processing drum in the low heat and humidity state is greater than the air outlet temperature of the laundry processing drum in the high heat and humidity state. Exemplarily, the low heat and humidity 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 heat and humidity state is a state in which the air outlet temperature of the laundry processing drum 1 is less than the first set temperature.

[0093] When the outlet air temperature of the clothing treatment drum 1 is greater than the second set temperature, it indicates that the drying and dehumidification stage has been completed, and the drying and drying judgment stage is entered. In the drying and drying judgment stage, when the temperature difference between the inlet air temperature and the outlet air temperature reaches the dryness judgment temperature difference for the set number of times, it indicates that the clothes in the drum have been dried, and at this time, the heat pump component is controlled to be closed.

[0094] In order to prevent the user from being scalded by the hot air flow in the drum when opening the door, the temperature in the drum needs to be monitored before the drying program ends. When the temperature in the drum is higher than the fourth set temperature, the drying and cooling stage is entered. At this time, the condensing device 6 needs to be controlled to start, and the auxiliary fan 22 needs to be controlled to start. The airflow in the auxiliary air duct 32 is cooled by the condensing device 6 and then passed into the clothing treatment drum 1 to achieve rapid cooling of the drum. In addition, when the condensing device 6 has a spray part 61, the water mist sprayed by the spray part 61 can also enter the clothing treatment drum 1 with the airflow, further improving the cooling effect on the clothing treatment drum 1. Furthermore, the first damper component 7 is controlled to be in the second position, and the damper component 7 is controlled to be in the second position, so that the cooled airflow in the auxiliary air duct 32 is directly passed into the clothing treatment drum 1, and the low-temperature airflow in the auxiliary air duct 32 is prevented from entering the main air duct 31 through the connecting air duct 33 and being heated by the residual heat of the condenser 5, thereby reducing the cooling effect on the clothing treatment drum 1. Refer to Figure 4 Airflow diagram.

[0095] In the cooling stage, the main fan 21 can be kept in the started state to increase the air intake of the clothes processing drum 1 and further improve the cooling efficiency. The main fan 21 can also be in the turned-off state to reduce energy consumption.

Exemplarily, the low heat and humidity state is a state in which the air outlet temperature of the laundry treatment drum 1 is greater than or equal to the first set temperature and less than the second set temperature, and the high heat and humidity state is a state in which the air outlet temperature of the laundry treatment drum 1 is less than the first set temperature.
