In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply that they are different.

[0056] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0057] To address the technical problem of poor dehumidification effect caused by unreasonable air duct design and fan operation strategy in traditional heat pump clothing processing equipment, which affects drying and dehumidification efficiency and leads to high energy consumption during the drying process, this embodiment proposes a drying system, which includes:

[0058] A duct assembly includes a main duct, an auxiliary duct, and a connecting duct. The main duct has a first air inlet and a first air outlet, and the duct wall of the main duct is provided with a first connecting port. The auxiliary duct has a second air inlet and a second air outlet, and the duct wall of the auxiliary duct is provided with a second connecting port. The connecting duct connects the first connecting port and the second connecting port.

[0059] A main fan and an auxiliary fan, wherein the main fan is located in the main air duct and the auxiliary fan is located in the auxiliary air duct;

[0060] A heat pump assembly includes an evaporator and a condenser, both of which are located within the main air duct, with the condenser positioned downstream of the evaporator in the direction of airflow.

[0061] A condensation device is installed in the auxiliary air duct and is used to condense the airflow in the auxiliary air duct.

[0062] This embodiment increases the airflow during the clothes drying process and improves drying efficiency by adding an auxiliary air duct and an auxiliary fan, and connecting the auxiliary air duct to the main air duct. Furthermore, this embodiment further improves the drying efficiency by installing a condenser in the auxiliary air duct. During the drying and dehumidification stage, the condenser condenses the hot, humid airflow entering the auxiliary air duct before it enters the clothes processing drum, reducing the load on the heat pump components and improving dehumidification. During the drying and cooling stage, the condenser cools the airflow entering the auxiliary air duct before it enters the clothes processing drum, improving cooling efficiency and shortening the overall clothes drying time.

[0063] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following implementation methods and examples can be combined with each other.

[0064] This embodiment proposes a drying system, such as Figure 1As shown, the drying system includes an air duct assembly, a main fan 21, an auxiliary fan 22, a heat pump assembly, and a condenser unit 6, wherein:

[0065] 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 and a first air outlet 311, and its duct wall has a first connecting port 312. The auxiliary air duct 32 has a second air inlet and a second air outlet 321, and its duct wall has a second connecting port 322. The connecting air duct 33 connects the first connecting port 312 and the second connecting port 322. In the application scenario of the garment processing equipment, a circulating air path is formed between the garment processing cylinder 1 and the main air duct 31, and a circulating air path is formed between the garment processing cylinder 1 and the auxiliary air duct 32. The main fan 21 is located in the main air duct 31 to facilitate airflow in the circulating air path formed between the garment processing cylinder 1 and the main air duct 31. The auxiliary fan 22 is located in the auxiliary air duct 32 to facilitate airflow in the circulating air path formed between the garment processing cylinder 1 and the auxiliary air duct 32.

[0066] The heat pump assembly includes an evaporator 4 and a condenser 5, both of which are located within the main air duct 31. The condenser 5 is positioned downstream of the evaporator 4 in the direction of airflow. The evaporator 4 and condenser 5 can be installed independently within the main air duct 31, or they can be integrated into a single structure and installed as a whole within the main air duct 31.

[0067] The heat pump assembly also includes a compressor and a throttling device. The compressor, condenser 5, throttling device, and evaporator 4 are sequentially connected to form a refrigerant circulation 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 towards the evaporator 4. After absorbing heat in the evaporator 4, 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 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 start-up state to allow the refrigerant to circulate in the refrigerant circulation path.

[0068] The condenser 6 is located in the auxiliary air duct 32 and is used to condense the airflow within the duct. During the drying process, with the auxiliary fan 22 and the condenser 6 running, the airflow in the auxiliary air duct 32 can be condensed by the condenser 6 and then directly blown into the clothes processing drum 1 through the auxiliary air duct 32. This reduces the temperature and humidity of the airflow entering the clothes processing drum 1, regulating the temperature and relative humidity inside the drum and ensuring that neither device operates under high humidity conditions. Furthermore, after drying, the condenser 6 can also reduce the temperature of the airflow in the auxiliary air duct 32 before sending it into the clothes processing drum 1 to quickly lower the temperature inside the drum, preventing users from being burned by the high-temperature airflow inside the drum when opening the door of the clothes processing equipment.

[0069] In the application scenario of clothing processing equipment, the drying system of this embodiment can dehumidify and cool the airflow in the auxiliary air duct 32 through the condenser 6, thereby improving the dehumidification efficiency of the drying and dehumidification stage and shortening the cooling time of the drying and cooling stage, thus improving the user experience.

[0070] Specifically, during the clothes drying process, in the early drying and heating stage, the main fan 21 and the heat pump assembly are turned on. The condenser 5 in the heat pump assembly heats the airflow in the main air duct 31 and sends it into the clothes processing drum 1 to raise the temperature inside the clothes processing drum 1.

[0071] When the temperature inside the cylinder rises to a certain level and the cylinder is in a high humidity and heat state, the auxiliary fan 22 and the condenser 6 are turned on. The condenser 6 lowers the airflow temperature in the auxiliary air duct 32, thereby reducing the temperature inside the cylinder and increasing the relative humidity to the dew point temperature. The high temperature and high humidity gas condenses into water and is discharged outside the cylinder, avoiding the two devices from operating under high operating conditions. In addition, the left and right air ducts simultaneously send air into the cylinder, further improving the dehumidification efficiency and accelerating the drying speed.

[0072] When the inside of the cylinder is in a low humidity and heat state, a large amount of drying airflow is not required, and the auxiliary fan 22 and condenser 6 are turned off.

[0073] After drying, the temperature inside the drum is still high, which may cause burns when removing clothes. At this time, the heat pump component stops starting, and the auxiliary fan 22 and condenser 6 start. The damper component is in the first position, and the airflow in the auxiliary air duct 32 is cooled by the condenser 6 before entering the clothes handling drum 1, thereby increasing the cooling speed. During the cooling phase, the main fan 21 can remain running to increase the air intake of the clothes handling drum 1 to further accelerate the cooling speed, or it can be shut down to reduce energy consumption.

[0074] In one example, the condensing device 6 is a water-cooled condensing device, which includes a spray section 61 and a water supply section 62. The spray section 61 is located at the top of the auxiliary air duct 32, and the spray direction of the spray section 61 faces the interior of the auxiliary air duct 32. The water supply section 62 is connected to the spray section 61 and is used to supply water to the spray section 61. The water supply section 62 includes a water supply pipe and a water valve located on the water supply pipe. The water supply pipe is connected to the municipal water supply line in the user's home, and the water valve controls the water supply line to supply water to the spray section 61. During the drying and cooling stage, the water mist sprayed from the spray section 61 can also enter the clothes processing drum 1 with the airflow in the auxiliary air duct 32, further accelerating the cooling speed.

[0075] Preferably, the multiple spray holes of the spray section 61 are arranged along the width direction of the auxiliary air duct 32 to improve the uniformity of water mist distribution in the airflow. Simultaneously, during the drying and dehumidification stages and the drying and cooling stages, it also enhances the cooling and dehumidification effect on the airflow within the auxiliary air duct 32. When the condenser 6 is turned on, the water valve opens, allowing water from the water supply pipe to continuously flow into the spray section 61 and spray out from the spray holes of the spray section 61.

[0076] More preferably, the spray section 61 is located at the position corresponding to the second connecting port 322 in the auxiliary air duct 32, or the spray section 61 is located upstream of the second connecting port 322 in the airflow direction, and the spray direction of the spray section is towards the auxiliary air duct, so that the water mist sprayed by the spray device can enter the connecting air duct 33 with the airflow in the auxiliary air duct 32, and finally enter the main air duct 31 and blow directly onto the evaporator 4 to reduce the load on the evaporator 4, or blow directly onto the condenser 5 without passing through the evaporator 4, and heat the water mist into wet steam through the condenser 5, thereby realizing the steam care function.

[0077] In other possible implementations, the condensation device 6 may include water condensation pipes that are wound around the inner or outer wall of the auxiliary air duct 32, or may include multiple water tanks that are opened on the inner or outer wall of the auxiliary air duct 32, which will not be listed here.

[0078] In one alternative implementation, such as Figure 2 As shown, the drying system also includes a first damper component 701 and a second damper component 702, wherein:

[0079] The first damper component 701 is movably disposed in the auxiliary air duct 32 and located on the side of the condenser 6 near the second air outlet 321. The first damper component 701 has a first position that blocks the airflow passage between the auxiliary fan 22 and the second air outlet 321, and a second position that opens the airflow passage between the auxiliary fan 22 and the second air outlet 321. The first damper component 701 can be controlled in the first position or the second position. The second damper component 702 is movably disposed in the connecting air duct 33. The second damper component 702 has a third position that blocks the airflow passage between the connecting air duct 33 and the main air duct 31, and a fourth position that opens the airflow passage between the connecting air duct 33 and the main air duct 31. The second damper component 702 can be controlled in the third position or the fourth position.

[0080] In this embodiment, by setting a first damper component 701 and a second damper component 702, the airflow path between the auxiliary air duct 32, the connecting air duct 33 and the main air duct 31 can be flexibly adjusted to further improve dehumidification efficiency and shorten drying time.

[0081] Specifically, during the drying and heating stage, the second damper component 702 is positioned in the third position to prevent the airflow in the main air duct 31 from entering the connecting air duct 33 and causing heat loss, thereby reducing the heating effect inside the cylinder.

[0082] And / or, during the drying and dehumidification stage, when the clothes processing drum 1 is in a high humidity and heat state, the first damper component 701 is positioned in the second position so that the airflow dehumidified by the condenser in the auxiliary air duct 32 can directly enter the clothes processing drum 1 through the auxiliary air duct 32 to regulate the temperature and humidity inside the clothes processing drum 1. Alternatively, when the clothes processing drum 1 is in a high humidity and heat state, while the first damper component 701 is in the second position, the second damper component 702 is controlled to be in the third position to avoid mutual interference between the airflows in the main air duct 31, which would reduce the cooling and dehumidification effect.

[0083] And / or, during the drying and dehumidification stage, when the clothes processing drum 1 is in a low humidity and heat state, the second damper component 702 is placed in the third position to prevent the airflow in the main air duct 31 from entering the connecting air duct 33 and causing heat loss, thereby reducing the dehumidification effect inside the drum.

[0084] And / or, during the drying and cooling stage, the first damper component 701 is controlled in the second position and the second damper component 702 is controlled in the third position at the same time, so that the airflow in the auxiliary air duct 32 after being cooled by the condenser can directly enter the clothes processing drum 1 through the auxiliary air duct 32 to quickly cool the clothes processing drum 1, and avoid the low-temperature airflow in the auxiliary air duct 32 from being heated by the residual heat of the condenser 5 after entering the main air duct 31, thus reducing the cooling effect on the clothes processing drum 1.

[0085] For example, the first damper component 701 includes a first baffle and a first motor that drives the first baffle to move. The first baffle includes a first end 711 and a second end 712 that are disposed opposite to each other. The auxiliary air duct 32 includes a first sidewall and a second sidewall that are disposed opposite to each other. The first end 711 is movably connected to the first sidewall. When the first damper component 701 is in the first position, the second end 712 is connected to the second sidewall to block the airflow passage between the auxiliary fan 22 and the second air outlet 321. When the first damper component 701 is in the second position, the second end 712 is separated from the second sidewall to open the airflow passage between the auxiliary air duct 32 and the second air outlet 321.

[0086] And / or, the second damper component 702 includes a second baffle and a second motor that drives the second baffle to move. The second baffle includes a third end 721 and a fourth end 722 that are disposed opposite to each other. The connecting duct 33 includes a third sidewall and a fourth sidewall that are disposed opposite to each other. The third end 721 is movably connected to the third sidewall. When the second damper component 702 is in the third position, the fourth end 722 is connected to the fourth sidewall to block the airflow passage between the connecting duct 33 and the evaporator 4. When the damper component is in the fourth position, the fourth end 722 is separated from the fourth sidewall to open the airflow passage between the connecting duct 33 and the main duct 31.

[0087] In one alternative implementation, the evaporator 4 is located downstream of the first connection port 312 in the airflow direction, so that when the second damper component 702 is in the fourth position, the airflow entering the connecting air duct 33 from the auxiliary air duct 32 can flow directly to the evaporator 4, increasing the airflow into the evaporator 4 and the condenser 5 and increasing the dehumidification efficiency.

[0088] In one alternative implementation, the first damper component 701 is located near the second connection port 322 in the auxiliary air duct 32. When the first damper component 701 is in the first position and the auxiliary fan 22 is running, the airflow in the auxiliary air duct 32 can enter the connecting air duct 33 more smoothly.

[0089] And / or, the second damper component 702 is located near the first connection port 312 of the connecting duct 33, so that when the second damper component 702 is in the third position and the main fan 21 is running, excessive airflow is prevented from entering the connecting duct 33, thus ensuring the airflow volume of the main duct 31.

[0090] This embodiment proposes a clothing processing device with a drying function, such as... Figure 5 As shown, the clothing processing device of this embodiment may have only a drying function, or it may have both drying and washing functions simultaneously. The clothing processing device includes a housing, a clothing processing drum 1, a control device, and the drying system described above. Wherein:

[0091] A cavity is formed inside the shell, and a clothes processing cylinder 1 is provided inside the cavity. The clothes processing cylinder 1 is provided with a first air inlet, a second air inlet, and an air outlet. The first air outlet 311 is connected to the first air inlet, and the second air outlet 321 is connected to the second air inlet. Both the first air inlet and the second air inlet are connected to the air outlet so that the hot and humid airflow in the clothes processing cylinder 1 can flow into the main air duct 31 and / or the auxiliary air duct 32 through the air outlet. After being dehumidified and heated by the heat pump component in the main air duct 31, it enters the clothes processing cylinder 1 through the first air inlet to dry the clothes.

[0092] The locations of the first air inlet, the second air inlet, and the air outlet are not explicitly defined. In one example, the opening of the garment processing drum 1 is sealed with a door, and the first and second air inlets are located at the door. The air outlet is located at the bottom of the garment processing drum 1. This creates a relatively long airflow path between the first and second air inlets and the air outlet, allowing the airflow to penetrate the garments and ensuring a uniform drying effect.

[0093] In a preferred embodiment, there are two air outlets, with the first air inlet and the second air inlet respectively connected to 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. The two air outlets can be both located at the bottom of the clothes processing drum 1, or they can be located at different positions in the axial direction of the clothes processing drum 1, so as to form a circulating airflow at different positions in the clothes processing drum 1, which can also improve the drying effect of the clothes.

[0094] The control device is configured to control the operating status of the auxiliary fan 22 and the condenser 6 according to the stage of the clothes drying process, or to control the operating status of the auxiliary fan 22 and the condenser 6 according to the humid and hot state inside the clothes processing drum.

[0095] The clothing processing equipment in this embodiment improves the dehumidification efficiency of the drying and dehumidification stage and the cooling speed of the drying and cooling stage by adjusting the working status of the auxiliary fan 22 and the condenser 6 in different stages of the clothing drying process, thereby shortening the overall drying time and reducing drying energy consumption.

[0096] In one alternative implementation, the control device is further configured to control the position state of the first damper component 701 and / or the second damper component 702 according to the drying stage of the clothes during the clothes drying process.

[0097] In this embodiment, by setting a first damper component 701 and a second damper component 702, the airflow path between the auxiliary air duct 32, the connecting air duct 33 and the main air duct 31 can be flexibly adjusted to further improve dehumidification efficiency and shorten drying time.

[0098] In one optional implementation, the garment processing equipment further includes a first temperature detection device 8 and a second temperature detection device. The first temperature detection device 8 is located at the first air inlet and is used to detect the air inlet temperature of the garment processing drum 1. The second temperature detection device is located at the first air outlet and is used to detect the air outlet temperature of the garment processing drum 1. During the drying process, by monitoring the air inlet temperature and / or air outlet temperature of the garment processing drum 1, the drying stage of the garment and the humid and hot state inside the drum can be determined, thereby achieving the control of the drying process.

[0099] The drying process of the garment processing equipment in this embodiment will be described in detail below.

[0100] The clothes drying process includes a drying heating stage, a drying dehumidification stage, and a drying cooling stage, executed sequentially. During the clothes drying process, the main fan 21 and heat pump assembly are first started, and the airflow circulates between the clothes handling drum 1 and the main air duct 31. At this time, the second damper component 702 is controlled to be in the third position to prevent the airflow in the main fan 21 from entering the clothes handling drum 1 through the connecting air duct 33 and auxiliary air duct 32 without being dehumidified and heated by the heat pump assembly, thereby reducing the heating effect. (Refer to...) Figure 3 The airflow path is shown. Since the auxiliary fan 22 is in the off state at this time, the position of the first damper component 701 is not adjusted.

[0101] When the inlet and / or outlet air temperatures of the garment processing drum 1 reach the target temperature for the end of the drying and heating phase, the drying and heating phase ends, and the drying and dehumidification phase begins.

[0102] During the drying and dehumidification stage, when the drum is in a high-humidity and high-heat state, the humidity inside the drum is high, the evaporator 4 has a large load, and the dehumidification efficiency is low. At this time, by controlling the condenser 6 to start, the auxiliary fan 22 is started, so that the airflow inside the drum enters the auxiliary air duct 32 and is dehumidified by the condenser 6, thereby reducing the humidity inside the drum and reducing the load on the evaporator 4. Furthermore, by controlling the first damper component 701 to be in the second position, the airflow in the auxiliary air duct 32 can be cooled and dehumidified by the condenser 6 and then directly introduced into the clothes processing drum 1, thereby reducing the humidity inside the drum. The start of the auxiliary fan 22 also increases the air intake of the clothes processing drum 1, further improving the dehumidification efficiency. Figure 4 The airflow path is shown.

[0103] Under high humidity and heat conditions, the second damper component 702 can be controlled in the third position, at which time the airflow in the auxiliary air duct 32 is independent of the airflow in the main air duct 31. Alternatively, the second damper component 702 can be controlled in the fourth position, at which time the airflow in the auxiliary air duct 32, after being cooled and dehumidified by the condenser 6, can also enter the main air duct 31 through the connecting air duct 33, and then be further cooled and dehumidified by the evaporator 4, thereby reducing the load on the evaporator 4 and further improving the dehumidification effect.

[0104] When the cylinder is in a low-humidity and high-temperature state, the humidity inside the cylinder is low, and the evaporator 4 alone is sufficient for dehumidification. At this time, energy consumption is reduced by shutting down both the auxiliary fan 22 and the condenser 6. Furthermore, the second damper component 702 can be positioned in a third position to prevent airflow from the main duct 31 from entering the auxiliary duct 32 via the connecting duct 33 without dehumidification, thus preventing a reduction in dehumidification efficiency. (Refer to...) Figure 3 The airflow path is shown.

[0105] The low humidity and heat state is the state in which the air outlet temperature of the clothes 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 the state in which the air outlet temperature of the clothes processing drum 1 is less than the first set temperature.

[0106] When the outlet air temperature of the clothes processing drum 1 is greater than the second set temperature, it indicates that the drying and dehumidification stage has been completed, and then the drying and judging stage begins. In the drying and judging stage, the clothes in the drum are dried when the temperature difference between the inlet air temperature and the outlet air temperature reaches the judging temperature difference a set number of times. At this time, the heat pump component is controlled to shut down.

[0107] To prevent users from being scalded by the hot airflow inside the drum when opening the door, the drum temperature needs to be monitored before the drying program ends. If the drum temperature exceeds the third set temperature, the drying and cooling stage begins. This involves starting the condenser 6 and auxiliary fan 22. The airflow in the auxiliary air duct 32 is cooled by the condenser 6 and then enters the clothes processing drum 1 for rapid cooling. Furthermore, if the water condenser has a spray section 61, the water mist sprayed from the spray section 61 can also enter the clothes processing drum 1 with the airflow, further enhancing the cooling effect. Additionally, the first damper component 701 is controlled to the second position, and the second damper component 702 is controlled to the third position, allowing the cooled airflow in the auxiliary air duct 32 to directly enter the clothes processing drum 1. This prevents the low-temperature airflow in the auxiliary air duct 32 from entering the main air duct 31 and being heated by the residual heat of the condenser 5, thus reducing the cooling effect on the clothes processing drum 1.

[0108] During the cooling phase, the main fan 21 can remain running to increase the air intake of the clothes handling drum 1 and further improve the cooling efficiency. The main fan 21 can also be turned off to reduce energy consumption.

[0109] This embodiment also provides a drying method for a garment processing device. The drying method is applied to the garment processing device with drying function described above, as referred to below.

[0112] In one optional implementation, the starting state of the auxiliary fan 22 and the condenser 6 is controlled according to the clothes drying stage, or the operating state of the auxiliary fan 22 and the condenser 6 is controlled according to the humid and hot state inside the clothes processing drum 1, including:

[0113] During the drying and dehumidification stage, the start-up status of the auxiliary fan 22 and the condenser 6 is controlled according to the humid and hot state of the clothes processing drum 1.

[0114] And / or, during the drying and cooling stage, both the condenser 6 and the auxiliary fan 22 are kept in the start state.

[0115] In one alternative implementation, the activation status of the auxiliary fan 22 and the condenser 6 is controlled according to the humid and hot state of the clothing treatment drum 1, including:

[0116] When the clothes processing drum 1 is in a high humidity and heat state, the auxiliary fan 22 and the condenser 6 are both in the start state.

[0118] The low humidity and heat state is the state in which the air outlet temperature of the clothes 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 the state in which the air outlet temperature of the clothes processing drum 1 is less than the first set temperature.

[0119] In one alternative implementation, the drying method further includes:

[0120] During the drying and heating stage, the second damper component 702 is controlled to be in the third position;

[0121] And / or, when the clothes processing drum 1 is in a high humidity and heat state, the first damper component 701 is controlled to be in the second position, or the first damper component 701 is controlled to be in the second position and the second damper component 702 is controlled to be in the third position; when the clothes processing drum 1 is in a low humidity and heat state, the second damper component 702 is controlled to be in the third position.

[0122] And / or, during the drying and cooling stage, the first damper component 701 is controlled to be in the second position and the second damper component 702 is controlled to be in the third position.

[0125] In one specific implementation of the embodiments of this application, reference is made to Figure 5 Clothing processing equipment and Figure 7 The drying process flowchart shows that the clothing drying method includes the following processes:

[0139] In summary, this embodiment optimizes the airflow path between the clothes handling drum 1 and the main air duct by connecting the auxiliary air duct 32 and the main air duct 31 through the connecting air duct 33. Furthermore, by installing an auxiliary fan 22 in the auxiliary air duct 32, the air intake of the clothes handling drum 1 during the drying process is increased. The installation of a condenser 6 in the auxiliary air duct 32 controls the relative humidity inside the drum, reducing the load on the evaporator 4 and rapidly lowering the temperature inside the drum after drying. This embodiment also adjusts the positions of the first damper component 701 and the second damper component 702 to ensure optimal airflow within the duct during the drying stage, further improving dehumidification efficiency and increasing the rate of temperature reduction inside the drum after drying, thereby reducing drying energy consumption.
