[0046] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

In addition, in order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0048] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. 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.

[0049] Because traditional drying equipment has limited heat transfer and air flow efficiency due to unreasonable air duct design and fan operation strategy, it has poor dehumidification effect on clothes, and also leads to increased equipment failure rate and energy waste.

[0050] In order to solve the above technical problems, 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 spaced apart from each other, the evaporator being disposed in a position corresponding to the communication port in the main air duct, and the condenser being disposed in the main air duct and downstream of the evaporator in the direction of air flow;

[0054] 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 to the condenser through the evaporator. The damper component can be controlled in the first position or the second position.

[0055] This embodiment connects the auxiliary air duct to the main air duct and positions the evaporator at the main duct's connection port, optimizing the airflow path and ensuring even distribution and efficient utilization of airflow in the evaporator area. Furthermore, this embodiment incorporates a damper component on the side of the evaporator near the auxiliary air duct, automatically adjusting its position to optimize the airflow path according to the drying stage. This allows for flexible adjustment and efficient utilization of air volume during the drying process, significantly improving the drying equipment's heating rate and dehumidification efficiency.

[0056] The following is a detailed description of the technical solution of this embodiment with reference to the accompanying drawings. The following embodiments and examples can be combined with each other unless they conflict.

[0057] Example 1

[0058] like Figure 1-Figure 3 As shown, this embodiment provides a drying system, which includes an air duct assembly, a main fan 21, an auxiliary fan 22, a heat pump assembly, and a damper component 7. 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 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 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 connected to the main air duct 31 directly or indirectly through a connecting air duct 321.

[0059] 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.

[0060] The heat pump assembly includes an evaporator 4 and a condenser 5 that are spaced apart. The evaporator 4 is located in the main air duct 31 at a position corresponding to the connecting port 322. The condenser 5 is located in the main air duct 31 and 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. 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, and forms dry and cold air after the evaporator 4 absorbs heat. 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.

[0061] 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.

[0062] 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 according to the humidity and heat state of the clothing processing drum 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.

[0063] For example, in the drying temperature rising stage at the early stage of drying, by controlling the damper component 7 to be in the first position, the air flow in the auxiliary air duct 32 can be directly blown to the condenser 5, thereby effectively increasing the air flow of the condenser 5. Figure 2 The airflow path is shown by the arrow in the middle. Since the condenser 5 can be used as a heat source during the heating stage, this can accelerate the transfer and distribution of heat, causing the temperature in the clothes processing drum 1 to rise rapidly, shortening the heating time and improving energy efficiency. After entering the drying and dehumidification stage, by adjusting the damper component 7 to the second position, the airflow in the auxiliary air duct 32 can flow through the evaporator 4 to the condenser 5, thereby increasing the airflow between the evaporator 4 and the condenser 5. Figure 3The airflow path is shown by the arrow in the middle. The evaporator 4 acts as a dehumidifying element at this stage. The high air volume passing through the evaporator 4 helps to quickly absorb and discharge the moisture in the clothes processing drum 1, achieving efficient dehumidification and ensuring the drying effect of the clothes.

[0064] In a preferred embodiment, the area of ​​the communication 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 more smoothly to the condenser 5 or the evaporator 4, further ensuring uniform distribution and efficient use of the air volume. In other feasible embodiments, similar effects can be achieved by arranging the condenser in a position not opposite the communication port.

[0065] Preferably, the condenser 5 is located between the connecting port 322 and the air inlet, and the air inlet end of the condenser is located downstream of the connecting port 322 in the direction of airflow, to ensure that when the damper component is in the first position, all airflow in the auxiliary air duct flows to the condenser. More preferably, the distance between the air inlet end of the evaporator and the end of the connecting port 322 close to the main fan is M1, and the distance between the air outlet end of the evaporator and the end of the connecting port away from the main fan is M2, where M1 = M2. This allows the airflow in the auxiliary air duct 32 to more smoothly enter the air inlet end of the condenser 5 when the damper component is in the first position, thereby improving the heating effect, and to more smoothly enter the air inlet end of the evaporator 4 when the damper component is in the second position, thereby improving the dehumidification effect.

[0066] In an optional implementation, 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 first end 72 that are relatively arranged. The first end 71 is movably connected to the side of the evaporator 4 close to the auxiliary air duct 32, and when the damper component 7 is in the first position, the first end 72 is connected to the side of the auxiliary air duct 32 away from the first air outlet end 311, so that the airflow in the auxiliary air duct 32 cannot flow to the evaporator 4, but can only flow directly to the condenser 5. When the damper component 7 is in the second position, the first end 72 is close to the auxiliary air duct 32, so that the airflow in the auxiliary air duct 32 cannot flow directly into the condenser 5, but first flows to the evaporator 4, and then flows into the condenser 5 through the evaporator 4. This embodiment can optimize the air path by adjusting the relative position between the baffle and the connecting port 322, has low production costs, and is easy to promote and implement.

[0067] Furthermore, before entering the drying process, the damper component is also controlled to be in the initial position, such as the first position. Since the clothes drying process generally enters the drying and heating stage first, by placing the damper component in the first position first, the movement of the damper component can be reduced and power consumption can be reduced.

[0068] Example 2

[0069] This embodiment proposes 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 of this embodiment includes a housing, a laundry processing drum 1, a control device and the drying system proposed in the first embodiment.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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, and to control the position state of the damper component 7 according to the clothes drying stage.

[0074] 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 based on the humidity and heat conditions within the clothes processing drum 1, achieving rapid heating and dehumidification, improving energy utilization, and effectively reducing energy consumption.

[0075] In an optional implementation, the laundry processing apparatus further includes a first temperature detection device and a second temperature detection device. The first temperature detection device is used to detect the inlet air temperature of the laundry processing drum 1, and the second temperature detection device is used to detect the outlet air temperature of the laundry processing drum 1. Preferably, the first temperature detection device is located at the first air outlet, and the second temperature detection device is located at the air inlet. The control device is further configured to determine the laundry drying stage based on the inlet air temperature and / or the outlet air temperature.

[0076] Specifically, if the inlet air temperature is lower than the first set temperature, the drying and heating phase is determined to be in progress. If the inlet air temperature reaches the first set temperature and the outlet air temperature is lower than the second set temperature, the drying and dehumidification phase is determined to be in progress. If the outlet air temperature is higher than the second set temperature, the initial drying phase ends and the drying determination phase begins. In other implementations, the drying phase can also be determined based on the humidity in the drum or the elapsed drying time.

[0077] The first set temperature and the second set temperature are related to the type of the clothes processing device, and their specific values ​​can be measured through experiments and stored in the control program.

[0078] Example 3

[0079] 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 in the second embodiment. Figure 5 The drying process flow chart of FIG. 1 shows a drying process flow chart of FIG. 1 , wherein the drying process includes the following steps:

[0080] 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;

[0081] S52: Determine the clothes drying stage, and control the position state of the damper component 7 according to the clothes drying stage.

[0082] In an optional implementation, controlling the position state of the damper component 7 according to the clothes drying stage includes:

[0083] During the drying and heating stage, the damper component 7 is controlled to be in the first position;

[0084] In the drying and dehumidifying stage, the damper component 7 is controlled to be in the second position.

[0085] In an optional implementation, the drying method further includes: adjusting the rotation speed of the main fan 21 and / or the auxiliary fan 22 according to the drying stage of the clothes.

[0086] In an optional implementation, adjusting the rotation speed of the main fan 21 and / or the auxiliary fan 22 according to the clothes drying stage includes:

[0087] During the drying and heating stage, the speed of the auxiliary fan 22 is controlled to be higher than the second speed, or the speed of the main fan 21 is controlled to be lower than the first speed and the speed of the auxiliary fan 22 is controlled to be higher than the second speed, so as to increase the air intake of the auxiliary air duct, increase the air flow that does not pass through the evaporator diameter and blow to the condenser, and improve the heating efficiency.

[0088] In the drying and dehumidification stage, the speed of the main fan 21 is controlled to be higher than the first speed, and the speed of the auxiliary fan 22 is controlled to be higher than the second speed, so as to increase the air flow through the evaporator and condenser, thereby quickly dehumidifying.

[0089] In an optional implementation, referring to Figure 6 The drying process diagram of the clothes is shown in Figure 1, which shows that the clothes drying stage includes the following steps:

[0090] S61, obtaining the air inlet temperature and air outlet temperature of the laundry processing drum 1;

[0091] S62: If the air inlet temperature is lower than the first set temperature, it is determined that the drying temperature is in the rising stage;

[0092] S63: When the air inlet temperature reaches the first set temperature and the air outlet temperature is lower than the second set temperature, it is determined that the system is in the drying and dehumidification stage.

[0093] The above control method has been described in detail in Embodiments 1 and 2 and will not be repeated here.

[0094] In the above embodiments of the present application, the descriptions of the various embodiments have their own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments. The steps shown in the relevant flow charts can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flow charts, in some cases, the steps shown or described can be executed in an order different from that shown here. In other words, the order of steps described in the foregoing embodiments is only an example, and reasonable adjustment of the order of steps based on the content of the embodiments of the present application is also within the scope of protection of the embodiments of the present application.

[0095] In a specific implementation of the embodiment of the present application, referring to Figure 7 The drying process flow chart of clothes includes the following processes:

[0096] S701, drying program starts;

[0097] S702: Control the compressor to start, control the main fan to start at a first speed, and control the auxiliary fan to start at a second speed;

[0101] S706, detecting the outlet air temperature;

[0102] S707: Determine whether the outlet air temperature is higher than the third set temperature Tw. If yes, the wet load in the drum is low and dehumidification is not required, and the process proceeds to step S710. If no, the process proceeds to step S708.

[0103] S708: Entering the drying and dehumidification stage, controlling the damper component to the second position, controlling the main fan speed to be higher than the first speed, and controlling the auxiliary fan speed to be higher than the second speed, so that the air volume passing through the evaporator and condenser is increased, and rapid dehumidification is achieved in the cylinder;

[0104] S709: Determine whether the air outlet temperature is higher than the second set temperature T2. If yes, the drying and dehumidification phase ends and the process proceeds to S710. If no, the process returns to S706.

[0105] S710, determine whether the drying condition is met, if the determination result is yes, the drying process ends, if the determination result is no, return to S702.

[0107] This not only speeds up the heating process but also enhances the dehumidification capacity, thereby significantly improving the overall drying efficiency.
