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 expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0050] To address the technical problem of limited dehumidification efficiency due to the limited internal space of traditional heat pump drying equipment, which prevents the volume of the two devices (evaporator and condenser) from being increased, this embodiment proposes a drying system, which includes:

[0051] An air duct assembly includes 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 a connecting port is provided on the air duct wall of the main air duct, 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 auxiliary fan are located in the main air duct and the auxiliary fan is located in the auxiliary air duct;

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

[0054] A condensing device is provided in the auxiliary air duct and is used to condense the air flow 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 in which the airflow in the auxiliary air duct flows directly to the condenser without passing through the evaporator, and a second position in which the airflow in the auxiliary air duct flows through the evaporator to the condenser. The damper component can be controlled in the first position or the second position.

[0056] This embodiment connects the auxiliary air duct with the main air duct, and the evaporator is set at a position corresponding to the connecting port, and a movable damper component is set on the side of the evaporator close to the auxiliary air duct, so as to realize controlling 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 realize rapid temperature rise in the drum, or the airflow in the auxiliary air duct flows to the condenser through the evaporator, thereby increasing the excess air volume of the evaporator and the condenser to realize efficient initialization; and, this embodiment further sets a condensing device in the auxiliary air duct, and can control the starting state of the condensing device 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 with reference to the accompanying drawings. The following embodiments and examples may be combined with each other unless there is any 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 and a first air outlet 311, and a connecting port 322 is provided on the air duct wall of the main air duct 31. The auxiliary air duct 32 has a second air inlet and a second air outlet, and the second air outlet is connected to the main air duct 31 through the connecting port 322. The auxiliary air duct 32 can be connected to the main air duct 31 directly or indirectly through a connecting air duct 321.

[0060] In the application scenario of the laundry processing device, a circulating air path is formed between the laundry processing drum 1 and the main air duct 31, and a circulating air path is formed between the laundry 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 circulate air in the circulating air path formed between the laundry 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 circulate air in the circulating air path formed between the laundry 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 spaced apart in the main air duct 31. The condenser 5 is located downstream of the evaporator 4 in the direction of air flow. 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 and / or the auxiliary fan 22, the hot and humid air entering the main air duct 31 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 clothing treatment drum 1 to dry the clothes in the clothing treatment 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.

[0062] The condensing device 6 is arranged in the auxiliary air duct 32, and is used to condense the air flow in the auxiliary air duct 32. During the drying process, when the auxiliary fan 22 is started, the air flow 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 portion 61 and a water supply portion 62. The spraying portion 61 is provided at the top of the auxiliary air duct 32, and the spraying direction of the spraying portion 61 is toward the inside of the auxiliary air duct 32. The water supply portion 62 is used to supply water to the spraying portion 61. The water supply portion 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 spraying portion 61. Preferably, the multiple spray holes of the spraying portion 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, improve the dehumidification effect of the air flow in the auxiliary air duct 32 during 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 portion 61 and is sprayed out from the spray holes of the spraying portion 61. In other possible implementations, the condensing device 6 may also be a water condensing pipe wound around the inner wall or outer wall of the auxiliary air duct 32, or a plurality of water troughs 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 through the evaporator 4 to the condenser 5. 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 that drives 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 on the side close to the auxiliary air duct 32, so that the airflow in the auxiliary air duct 32 can flow more smoothly to the condenser 5 or the evaporator 4, further ensuring the uniform distribution and efficient use of the air volume. Further preferably, the distance between the air inlet end of the evaporator and the end of the connecting port 322 close to the main fan 21 is M1, and the distance 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 amount of 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 amount of airflow in the auxiliary air duct 32 is blown to the condenser 5 through the evaporator 4. In other possible implementations, similar technical effects can be achieved by locating the condenser 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 hot and humid 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 includes a housing, a laundry processing drum 1, a control device and the drying system proposed above.

[0069] The housing forms a cavity within which a laundry treatment drum 1 is disposed. The laundry treatment drum 1 is provided with an air inlet and an air outlet, the locations of which are not specifically defined. In one example, a door seal is provided at the opening of the laundry treatment drum 1, with the air inlet located within the seal. The air outlet is located at the bottom of the laundry treatment drum 1, creating a long airflow path between the inlet and outlet, allowing airflow to penetrate the laundry, ensuring uniform drying of the laundry.

[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, enter the clothing processing drum 1 through the air inlet to dry the clothes.

[0071] In a preferred embodiment, there are two air outlets, with the first air inlet and the second air inlet communicating with the two air outlets in a one-to-one correspondence, thereby increasing the air intake of the auxiliary air duct 32 and the main air duct 31. Both air outlets can be located at the bottom of the laundry processing drum 1, or at different positions along the axial direction of the laundry processing drum 1, so as to deliver airflow to different positions within the laundry processing drum 1, thereby also improving 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 hot and humid state of the clothes processing drum 1 in the drying and dehumidification stage.

[0073] During the clothes drying process, this embodiment controls the simultaneous activation of the main fan 21 and the auxiliary fan 22 to increase the airflow into the clothes processing drum 1, improve heating and dehumidification efficiency, and shorten drying time. Furthermore, by controlling the position of the damper component 7 according to the clothes drying stage, the airflow path is optimized to achieve rapid heating and dehumidification. Alternatively, during the drying and dehumidification phase, this embodiment controls the operating state of the condensing device 6 according to the heat and humidity of the clothes processing drum 1, further improving dehumidification efficiency and shortening drying time.

[0074] The laundry processing apparatus of this embodiment further includes a temperature detection device disposed within the laundry processing drum 1 for detecting the temperature within the laundry processing drum 1. The control device is configured to, during the drying and cooling phase, control the heat pump assembly and the main fan 21 to be turned off, and to control the activation of the auxiliary fan 22 and the condensing device 6 based on the temperature within the drum.

[0075] After the drying and cooling phase, this embodiment controls the heat pump assembly and main fan 21 to shut down to prevent further temperature rise inside the drum. Furthermore, the drum temperature is monitored and the activation of the auxiliary fan 22 and condensing device 6 is controlled accordingly to ensure that the drum temperature is reduced to a level that will not burn the user.

[0076] Specifically, when the temperature inside the drum is greater than the third set temperature, it means that the temperature inside 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. The condensing device 6 cools the airflow in the auxiliary air duct 32, and the cooled airflow enters the clothing treatment drum 1 to achieve rapid cooling in the drum. When the temperature inside the drum is less than or equal to the third set temperature, it means that the temperature inside 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 process 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 drum 1 along with the airflow in the auxiliary air duct 32, further enhancing the cooling effect of the temperature inside the drum.

[0077] Furthermore, before entering the drying process, the damper component 7 is also controlled to be in the initial position, for example, the first position. Since the clothes 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, which is applied to the clothes processing device with a drying function proposed above. Figure 5 As shown in the drying flow chart, the drying method includes the following steps:

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

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

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

[0082] During the clothes drying process, this embodiment controls the simultaneous activation of the main fan 21 and the auxiliary fan 22 to increase the airflow into the clothes processing drum 1, improving heating and dehumidification efficiency and shortening drying time. Simultaneously, the position of the damper component 7 is controlled according to the clothes drying stage to optimize the airflow path and achieve rapid heating and dehumidification. This embodiment also controls the operating state of the condensing device 6 during the drying and dehumidification phase based on the heat and humidity of the clothes processing drum 1, further improving dehumidification efficiency and shortening drying time.

[0083] Furthermore, the position state of the damper component 7 is controlled according to the clothes drying stage, 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 air flow in the auxiliary air duct 32 can be blown directly to the condenser 5 without passing through the evaporator 4, thereby increasing the air flow of the condenser 5 and rapidly heating the clothes processing drum 1. Figure 2 In the drying and dehumidification stage, the damper component 7 is controlled to be in the second position, so that the air flow in the auxiliary air duct 32 passes through the evaporator 4 and the condenser 5, increasing the air flow of the evaporator 4 and the condenser 5 and improving the dehumidification efficiency. Figure 3 The drying stage can be determined according to the inlet air 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 heat and humidity state of the laundry treatment tub 1, including:

[0086] When the laundry tub 1 is in a high-humidity and high-heat state, the condensing device 6 is controlled to be in an activated state, so that the water mist sprayed by the condensing device 6 condenses the airflow in the auxiliary air duct 32, thereby reducing the load on the evaporator 4. At the same time, the airflow through the evaporator 4 and condenser 5 is increased, improving the dehumidification efficiency and shortening the drying time. When the laundry tub 1 is in a low-humidity and low-heat state, the condensing device 6 is controlled to be in an inactivated state, which increases the airflow through the evaporator 4 and condenser 5, ensuring the dehumidification effect while reducing energy consumption.

[0087] In this embodiment, the high-humidity and heat state refers to a state in which the humidity inside the drum is high in a high-temperature environment, while the low-humidity and heat state refers to a state in which the humidity inside the drum is low in 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. For example, the low-humidity and heat state refers to a state in which the air outlet temperature of the laundry processing drum 1 is greater than or equal to a first set temperature and less than a second set temperature, while the high-humidity and heat state refers to 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 rate that blows directly 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 when the clothes processing drum 1 is in a high humidity and heat state, the speed of the auxiliary fan 22 is controlled to be higher than the second 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 clothes processing drum 1.

[0090] And / or, in the drying and dehumidification stage, when the clothes processing drum 1 is in a low-humidity and low-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 component and the main fan 21 to turn off; obtaining the temperature inside the clothing processing drum 1, and when the temperature inside the drum is greater than the third set temperature, controlling the auxiliary fan 22 and the condensing device 6 to be in the started state; when the temperature inside the drum is less than or equal to the third set temperature, controlling the auxiliary fan 22 and the condensing device 6 to turn off.

[0092] In the drying and cooling stage, this embodiment controls the heat pump assembly and the main fan 21 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. 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, if the temperature inside the drum is greater than the second set temperature, indicating that the temperature inside the drum is high, the condensing device 6 and the auxiliary fan 22 are controlled to be in the activated state, so that the air in the auxiliary air duct 32 is cooled by the condensing device 6 before entering the clothing processing drum 1, achieving rapid cooling of the drum. Preferably, if the temperature inside the drum is greater than the second set temperature, the speed of the auxiliary fan 22 is increased to greater than the first initial speed to shorten the cooling time. If the temperature inside the drum is less than or equal to the second set temperature, indicating that the temperature inside the drum has reached a temperature that will not burn the user, the condensing device 6 and the auxiliary fan 22 are controlled to be turned off, and the drying process ends.

[0109] In general, this embodiment connects the auxiliary air duct 32 with the main air duct 31, and sets a condensing device 6 in the auxiliary air duct 32. The evaporator 4 is set at a position corresponding to the connection port 322. The position of the damper component 7 provided on the side of the evaporator 4 near the auxiliary air duct 32 is controlled to achieve rapid heating, dehumidification, and cooling of the laundry treatment drum 1. In the drying and heating stage, by controlling the damper component 7 to be in the first position, the air flow in the auxiliary air duct 32 flows directly to the condenser 5 without passing through the evaporator 4, thereby increasing the air flow of the condenser 5 and achieving rapid heating in the drum. In the drying and dehumidification stage, by controlling the damper component 7 to be in the second position, the air flow in the auxiliary air duct 32 is cooled by the condensing device 6 before flowing to the evaporator 4, thereby reducing the load on the evaporator 4 and improving the dehumidification efficiency. In the drying and cooling stage, the air flow in the auxiliary air duct 32 is cooled by the condensing device 6 before entering the laundry treatment drum 1, achieving rapid cooling in the drum and preventing the user from being burned by the high temperature in the drum when opening the door of the laundry treatment device to take out the clothes.
