[0016] And / or, the second damper component is located in the connecting duct near the first connection port.

[0017] According to a second aspect of the embodiments of this application, a garment processing device with a drying function is provided, the garment processing device comprising:

[0018] A garment processing drum, comprising a first air inlet, a second air inlet, and an air outlet;

[0019] The drying system proposed in the first aspect of the embodiments of this application has a first air outlet connected to a first air inlet, a second air outlet connected to a second air inlet, and both the first air inlet and the second air inlet connected to the air outlet.

[0020] The control device is configured to, in steam care mode, control the start-up of the heat pump assembly and the main fan, and control the operating status of the auxiliary fan and the spray device according to the temperature at the target location of the garment treatment drum, as well as control the position status of the first damper component.

[0021] According to the embodiments of this application, the clothing treatment device connects the auxiliary air duct and the main air duct through a connecting air duct, and installs a spray device in the auxiliary air duct. The condenser of the heat pump component heats the water mist to generate wet steam, thereby realizing the steam care function of the heat pump clothing treatment device. It does not occupy the internal space of the clothing treatment device, and can also allow the airflow of the auxiliary air duct to enter the main air duct, thereby increasing the airflow of the condenser and reducing heat waste.

[0027] According to the steam care method of this application embodiment, in steam care mode, the condenser and clothes treatment drum are rapidly heated by controlling the start of the heat pump component and the main fan, so that the heat released by the condenser is sufficient to turn water mist into wet steam. At the same time, the inside of the clothes treatment drum reaches the temperature conditions for steam care, preventing water mist from entering the clothes treatment drum and condensing into water droplets, thus avoiding reducing the steam care effect. Furthermore, this embodiment monitors the temperature at a further target location to determine whether the temperature inside the condenser and drum has reached the temperature conditions for steam care. This allows for the control of the start-up status of the auxiliary fan and the spray device, as well as the position of the first damper component. This ensures that when the temperature at the target location reaches the steam care conditions, the airflow generated by the auxiliary fan drives the water mist sprayed by the spray device, which is then heated by the condenser to generate wet steam that enters the clothes treatment drum for steam care.

[0035] In conjunction with the third aspect, in one optional implementation of the embodiments of this application, the temperature at the target location is the inlet air temperature of the first air inlet.

[0036] In conjunction with the third aspect, in an optional implementation of the embodiments of this application, the steam care method further includes:

[0037] When the conditions for ending steam treatment are met, the heat pump assembly is controlled to shut down;

[0038] The temperature inside the garment processing drum is obtained. If the temperature inside the drum is greater than the second set temperature, the auxiliary fan and the spray device are controlled to start, and the first damper component is controlled to be in the second position.

[0039] When the temperature inside the cylinder is less than or equal to the second set temperature, the main fan, the auxiliary fan, and the spray device are controlled to be in the off state.

[0040] According to a fourth aspect of the present application, a control device is provided, which includes a memory and a processor.

[0058] To address the technical problem that traditional heat pump garment processing equipment cannot achieve steam care, this embodiment proposes a drying system, which includes:

[0059] The air duct assembly includes a main air duct, an auxiliary air duct, and a connecting air duct. The main air duct has a first air inlet and a first air outlet, and the auxiliary air duct has a second air inlet and a second air outlet. The air duct wall of the main air duct is provided with a first connecting port, and the air duct wall of the auxiliary air duct is provided with a second connecting port. The connecting air duct connects the first connecting port and the second connecting port.

[0060] The main fan and the auxiliary fan are located in the main air duct and the auxiliary fan is located in the auxiliary air duct.

[0061] A heat pump assembly includes an evaporator and a condenser, both of which are located in the main air duct. In the direction of airflow, the evaporator is located upstream of the condenser, and the condenser is located downstream of the first connection port.

[0062] A spraying device includes a spraying section and a water supply section. The water supply section is connected to the spraying section and is used to supply water to the spraying section. The spraying section is located at the position of the auxiliary air duct corresponding to the second connecting port, or the spraying section is located upstream of the second connecting port in the airflow direction.

[0063] A first damper component is movably disposed in the auxiliary air duct and located on the side of the spray section near the second air outlet. The first damper component has a first position that blocks the airflow passage between the auxiliary fan and the second air outlet, and a second position that opens the airflow passage between the auxiliary fan and the second air outlet. The first damper component can be controlled in the first position or the second position.

[0064] The drying system in this embodiment connects the auxiliary air duct to the main air duct and installs a spray device in the auxiliary air duct. In the steam care mode, the auxiliary fan starts, and the airflow in the auxiliary air duct drives the water mist sprayed by the spray device to be heated into wet steam by the condenser. The steam then enters the clothes treatment drum and fully contacts and penetrates the clothes, achieving the care functions of wrinkle removal, odor removal, and sterilization.

[0065] 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 embodiments and examples can be combined with each other.

[0066] This embodiment proposes a drying system, such as Figures 1-4 As shown, the drying system includes an air duct assembly, a main fan 21, an auxiliary fan 22, a heat pump assembly, a spray device 6, and a first damper component 701, wherein:

[0067] 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.

[0068] The heat pump assembly includes an evaporator 4 and a condenser 5. Both the evaporator 4 and the condenser 5 are located within the main air duct 31, with the evaporator 4 located upstream of the condenser 5 and the condenser 5 located downstream of the first connecting port 312 in the airflow direction. The evaporator 4 and the condenser 5 can be independently located within the main air duct 31, or they can be integrated into a single structure and housed as a whole within the main air duct 31.

[0069] 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.

[0070] The sprinkler system 6 includes a sprinkler section 61 and a water supply section 62. The water supply section 62 is connected to the sprinkler section 61 and is used to supply water to the sprinkler 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. The water valve controls the water supply line to supply water to the sprinkler section 61. When the sprinkler system 6 is turned on, the water valve opens, allowing water in the water supply pipe to continuously flow into the sprinkler section 61 and spray out from the sprinkler holes of the sprinkler section 61.

[0071] The spray unit 61 is located in the auxiliary air duct 32 at a position corresponding to the second connecting port 322, or the spray unit 61 is located upstream of the second connecting port 322 in the airflow direction, and the spray direction of the spray unit is towards the inside of the auxiliary air duct. In steam care mode, when the auxiliary fan 22 is running, the water mist sprayed by the spray device 6 can enter the connecting air duct 33 with the airflow of the auxiliary fan 22, and then enter the main air duct 31 through the connecting air duct 33. It is heated by the condenser 5 in the main air duct 31 to form wet steam, which is then introduced into the garment treatment drum 1 to achieve steam care for the garments.

[0072] The first damper component 701 is movably disposed in the auxiliary air duct 32 and located on the side of the spray section 61 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 either the first or the second position. In this embodiment, in the steam care mode, the first damper component 701 can be controlled in the first position to prevent the water mist sprayed by the spray device 6 from directly entering the clothes treatment drum 1 without heating and wetting the clothes.

[0073] In addition, during the drying and dehumidification stage of the drying process, by placing the first damper component 701 in the second position, the airflow condensed by the spray device 6 in the auxiliary air duct 32 is directly introduced into the clothes processing drum 1 to accelerate the dehumidification efficiency inside the drum; during the drying and cooling stage, by placing the first damper component 701 in the second position, water mist can be directly introduced into the clothes processing drum 1 to accelerate the cooling speed inside the drum.

[0074] In this embodiment, the evaporator 4 can be positioned relative to the first communication port 312 in various ways.

[0075] In one feasible way, such as Figure 3 and Figure 4 As shown, the first connecting port 312 is located between the evaporator 4 and the condenser 5, as referenced. Figure 3 and Figure 4 In the orientation of the evaporator 4, the evaporator 4 is located above the first connecting port 312, and the condenser 5 is located below the first connecting port 312. That is, the first connecting port 312 is located between the air outlet side of the evaporator 4 and the air inlet side of the condenser 5. In the steam care mode, the water mist entering the connecting air duct 33 can flow directly to the condenser 5 without passing through the evaporator 4 and be heated by the condenser 5.

[0076] In one feasible manner (not shown in the example figure), the condenser 5 is positioned corresponding to the first connecting port 312, the area of ​​the first connecting port 312 is larger than the side area of ​​the condenser 5 near the auxiliary air duct 32, the distance between the air inlet end of the condenser 5 and the end of the first connecting port 312 near the main fan 21 is L1, and the distance between the air outlet end of the condenser 5 and the end of the first connecting port 312 away from the main fan 21 is L2, L1≥L2, so that the airflow in the auxiliary air duct 32 can flow more smoothly to the condenser 5.

[0077] In one feasible manner (not shown in the example figure), the evaporator 4 is positioned corresponding to the first connecting port 312, and the area of ​​the first connecting port 312 is larger than the side area of ​​the evaporator 4 near the auxiliary air duct 32. The air inlet of the condenser 5 is located downstream of the first connecting port 312 in the airflow direction. Preferably, the distance between the air inlet of the evaporator 4 and the end of the first connecting port 312 near the main fan 21 is M1, and the distance between the air outlet of the evaporator 44 and the end of the first connecting port 312 away from the main fan 21 is M2, where M1≤M2. This ensures that at least part of the airflow in the auxiliary air duct 32 can be blown directly to the condenser 5 without passing through the evaporator 44.

[0078] In one feasible way, such as Figure 1 and Figure 2 As shown, the air inlet of the evaporator 4 is located downstream of the evaporator 4 in the airflow direction. In steam care mode, the water mist entering the connecting air duct 33 is heated by the condenser 5 after passing through the evaporator 4. The position of the evaporator 4 relative to the first connecting port 312 in this embodiment also allows the airflow entering the connecting air duct 33 from the auxiliary air duct 32 to flow directly to the evaporator 4 during the cooling and dehumidification stage of the drying process, increasing the airflow into the evaporator 4 and condenser 5 and increasing the dehumidification efficiency.

[0079] In one optional implementation, the drying system further includes a second damper component 702, which 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 either the third or the fourth position. In this embodiment, in steam treatment mode, the airflow passage between the main air duct 31 and the connecting air duct 33 can be opened by controlling the second damper component 702 in the fourth position, so that the water mist entering the auxiliary air duct 32 can be blown towards the condenser 5 of the main air duct 31.

[0080] In addition, during the heating stage of the drying process, the second damper component 702 can be controlled in the third position to prevent the airflow in the main air duct 31 from entering the connecting air duct 33, thereby reducing the hot air output of the main air duct 31 and thus reducing the heating effect. During the cooling stage of the drying process, the second damper component 702 can be controlled in the third position to prevent the water mist sprayed by the spray device 6 from entering the main air duct 31 through the connecting air duct 33 and being heated by the residual heat of the condenser 5 before entering the clothes processing drum 1, thereby reducing the cooling effect on the clothes processing drum 1.

[0081] This embodiment sets up a second damper component 702 and coordinates the control of the first damper component 701 with the first damper component 701 to flexibly adjust the airflow path between the auxiliary air duct 32, the connecting air duct 33 and the main air duct 31, so as to achieve the best clothing treatment effect.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] This embodiment proposes a clothing processing device with a drying function. This device 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:

[0087] 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.

[0088] 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.

[0089] 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, to increase 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 deliver airflow to different positions in the clothes processing drum 1, which can also improve the drying effect of clothes.

[0090] The control device is configured to, in steam care mode, control the start of the heat pump assembly and the main fan 21, and control the working status of the auxiliary fan 22 and the spray device 6 according to the temperature at the target position of the garment treatment drum 1, as well as control the position status of the first damper component 701.

[0091] In this embodiment, under steam care mode, the heat pump component is started first, and the main fan 21 is rotated at a set speed to rapidly heat up the condenser 5 and the clothes handling drum 1. This ensures that the heat released by the condenser 5 is sufficient to turn the water mist into wet steam, and at the same time, the inside of the clothes handling drum 1 reaches the temperature conditions for steam care. This prevents water mist from entering the clothes handling drum 11 during the steam care process and condensing into water droplets, which would wet the clothes and reduce the steam care effect.

[0092] Furthermore, this embodiment further monitors the temperature at the target location to determine whether the temperature inside the condenser 5 and the cylinder has reached the temperature conditions for steam treatment. This allows for the control of the activation status of the auxiliary fan 22 and the spray device 6, as well as the control of the position of the first damper component 701. As a result, when the temperature at the target location reaches the steam treatment conditions, the airflow generated by the auxiliary fan 22 drives the water mist sprayed by the spray device 6 to be heated by the condenser 5 to generate wet steam, which then enters the clothing treatment cylinder 1 to perform steam treatment on the clothing.

[0093] Specifically, if the temperature at the target location is lower than the first set temperature, it means that the heat released by the condenser 5 is insufficient to turn the water mist sprayed by the spray device 6 into wet steam. At the same time, the low temperature inside the cylinder makes it easy for the wet steam to condense and wet the clothes. At this time, the auxiliary fan 22 and the spray device 6 are controlled to be in the off state.

[0094] When the temperature at the target location is greater than or equal to the first set temperature, it indicates that the heat released by the condenser 5 is sufficient to turn the water mist sprayed by the spray device 6 into wet steam. Simultaneously, the temperature inside the cylinder reaches a level where the wet steam is unlikely to condense. At this point, the auxiliary fan 22 and the spray device 6 are activated, and the first damper component 701 is positioned in the third position. This allows the water mist sprayed by the spray device 6 to enter the connecting duct 33 and the main duct 31 along with the airflow in the auxiliary duct 32, and be heated by the condenser 5 to form wet steam, which then enters the garment processing cylinder 1 to provide steam treatment for the garments inside. The airflow direction is referenced... Figure 6 As indicated by the middle arrow.

[0095] Preferably, when the temperature at the target location is greater than or equal to the first set temperature, the control device also controls the speed of the main fan 21 to be lower than the set speed, so that the airflow with water mist in the auxiliary air duct 32 can be heated more by the condenser 5, thereby improving the steam treatment effect.

[0096] The steam care mode in this embodiment can be executed according to the user's instructions, or it can be entered directly after the drying process. Because the clothes are at a high temperature and have many wrinkles after drying, the steam can fully contact the clothes and penetrate them to achieve the wrinkle removal effect.

[0097] In one alternative implementation, the garment processing device includes a second damper component 702, which 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 to be in the third position or the fourth position.

[0098] The control device is also configured to control the position of the second damper component 702 according to the temperature at the target location in steam care mode. Specifically, when the temperature at the target location is lower than the first set temperature, the second damper component 702 is controlled to be in the third position to prevent airflow in the main air duct 31 from entering the connecting air duct 33, thereby reducing the airflow volume of the main air duct 31 and reducing the heating efficiency of the garment processing equipment. When the inlet air temperature is greater than or equal to the first set temperature, the second damper component 702 is controlled to be in the fourth position so that the water mist entering the auxiliary air duct 32 can enter the main air duct 31 and be heated by the condenser 5 to form wet steam, which is then formed into the garment processing drum 1 to achieve steam care for the garments.

[0099] In one optional implementation, the garment processing equipment includes a first temperature detection device 8, which is located at the first air inlet and is used to detect the inlet air temperature of the garment processing drum 1, with the target location being the first air inlet. In other possible implementations, the target location may also be the inlet air temperature at the first air inlet of the garment processing drum 1, or the internal temperature of the garment processing drum 1.

[0100] In one alternative implementation, the garment processing equipment includes a second temperature detection device disposed inside the garment processing drum 11, for detecting the temperature inside the garment processing drum 11.

[0101] The control device is configured to control the start-up status of the auxiliary fan 22 and the spray device 6, as well as the position status of the first damper component 701, based on the temperature inside the cylinder when the steam treatment end conditions are met, so as to ensure that the temperature inside the cylinder is reduced to a temperature that will not burn the user.

[0102] Specifically, upon reaching the end condition for steam treatment, the heat pump assembly is first shut down to prevent further heating inside the drum. Then, the internal temperature of the garment processing drum 1 is measured. If the internal temperature exceeds the second set temperature, it indicates a high internal temperature. At this point, the auxiliary fan 22 and the spray device 6 are activated, and the first damper component 701 is positioned in the second position, allowing the water mist sprayed by the spray device 6 to enter the garment processing drum 1 through the auxiliary air duct 32, achieving rapid cooling inside the drum. The main fan 21 can remain activated to increase the airflow into the garment processing drum 1, further enhancing the cooling speed. The main fan 21 can also be shut down to reduce energy consumption. For example, when the steam treatment duration reaches the set duration, the steam treatment end condition is determined to have been met.

[0103] Preferably, when the temperature inside the cylinder is higher than the second set temperature, the speed of the auxiliary fan 22 is increased to a speed higher than that during the steam treatment process, so as to shorten the cooling time.

[0104] If the temperature inside the cylinder is less than or equal to the second set temperature, it means that the temperature inside the cylinder has reached a level that will not burn the user. At this time, the main fan 21, auxiliary fan 22 and spray device 6 are turned off, and the steam treatment stage ends.

[0105] This embodiment proposes a steam care method for clothing treatment equipment. The steam care method is applied to the clothing treatment equipment with drying function mentioned above, as described above. Figure 8 The flowchart shown illustrates the steam care method, which includes the following steps:

[0106] S81. In steam care mode, control the heat pump component to start and control the main fan 21 to rotate at the set speed;

[0107] S82. Obtain the temperature at the target location of the clothing processing drum 1, and control the working status of the auxiliary fan 22 and the spray device 6, as well as the position status of the first damper component 701, based on the temperature at the target location.

[0108] In one optional implementation, controlling the operating state of the auxiliary fan 22 and the spray device 6, and controlling the position state of the first damper component 701, based on the temperature at the target location, includes:

[0109] When the temperature at the target location is greater than or equal to the first set temperature, the auxiliary fan 22 and the spray device 6 are started, and the first damper component 701 is controlled to be in the first position.

[0110] In one alternative implementation, the steam care method further includes controlling the position state of the second damper component 702 according to the temperature at the target location.

[0111] In one alternative implementation, controlling the position state of the second damper component 702 based on the temperature at the target location includes:

[0112] If the temperature at the target location is lower than the first set temperature, control the second damper component 702 to be in the third position;

[0113] When the temperature at the target location is less than or equal to the first set temperature, the second damper component 702 is controlled to be in the fourth position.

[0114] In one alternative implementation, if the temperature at the target location is greater than or equal to a first set temperature, the rotational speed of the main fan 21 is also controlled to be lower than the set rotational speed.

[0115] In one alternative implementation, the temperature at the target location is the inlet air temperature of the first air inlet.

[0116] In one alternative implementation, refer to Figure 9 The flowchart shown indicates that the steam care method also includes the following steps:

[0117] S91. When the conditions for ending steam treatment are met, control the heat pump components to shut down;

[0118] S92. Obtain the temperature inside the garment processing drum 1;

[0119] S93. When the temperature inside the cylinder is greater than the second set temperature, control the auxiliary fan 22 and the spray device 6 to be in the start state, and control the first damper component 701 to be in the second position; when the temperature inside the cylinder is less than or equal to the second set temperature, control the main fan 21, the auxiliary fan 22 and the spray device 6 to be in the off state.

[0120] The detailed scheme of the above-mentioned steam care method has been described in detail in the embodiments of the drying system and clothing treatment equipment, and will not be repeated here.

[0121] In the above embodiments of this application, the descriptions of each embodiment have their own emphasis. Parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments. The steps illustrated in the related flowcharts can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown here. In other words, the order of steps described in the foregoing embodiments is merely an example. Reasonable adjustments to the order of steps based on the content of the embodiments of this application are also within the protection scope of the embodiments of this application.

[0122] In one specific implementation of the embodiments of this application, reference is made to Figure 7 The garment processing equipment shown Figure 10 The flowchart shown illustrates that the steam care method for garment processing equipment includes the following processes:

[0123] S101, Steam Care Mode Activated;

[0124] S102, control the heat pump assembly to be in the start state, control the main fan 21 to be in the start state at a set speed, control the second damper component 702 to be in the third position, and the condenser 5 heats up the airflow temperature entering the clothes processing drum 1 from the main air duct 31.

[0125] S103. Obtain the air temperature at the first air inlet;

[0126] S104. Determine whether the air inlet temperature is greater than or equal to the first set temperature. If the result is yes, proceed to S105. If the result is no, return to S102.

[0127] S105. Control the main fan 21 to run at a speed lower than the set speed, control the auxiliary fan 22 and the spray device 6 to start, control the first damper component 701 to be in the first position, and control the second damper component 702 to be in the fourth position. At this time, the airflow in the auxiliary air duct 32 is humidified by the spray device 6 and then enters the main air duct 31 through the connecting air duct 33. It is heated and evaporated into steam by the condenser 5 and finally enters the drum to steam care for the clothes. The steam can effectively soften the clothes and remove the wrinkles on the clothes.

[0128] S106. Determine whether the steam care termination condition has been met. If the result is yes, proceed to S107. If the result is no, return to S105.

[0129] S107. Turn off the heat pump assembly;

[0130] S108. Determine whether the temperature inside the cylinder is higher than the second set temperature. If the determination result is yes, proceed to S109. If the determination result is no, proceed to S110.

[0131] S109. Control the first damper component 701 to the second position, maintain the start-up state of the main fan 21, auxiliary fan 22 and spray device 6, cool the inside of the clothes processing drum 1, and return to S108.

[0132] S110, control the main fan 21, auxiliary fan 22 and spray device 6 to shut down, and the steam care mode ends.

[0133] In summary, this embodiment connects the auxiliary air duct 32 to the main air duct 31, and installs a spray device 6 in the auxiliary air duct 32. The condenser 5 is located downstream of the first connecting port 312 in the airflow direction. This allows for steam treatment during the steam conditioning process. By controlling the first damper component 701 in the first position and controlling the spray device 6 to spray water mist into the auxiliary air duct 32, the water mist travels with the airflow in the auxiliary air duct 32 through the connecting air duct 33 into the main air duct 31. The water mist is then condensed and heated to form wet steam, which enters the garment processing drum 1 to achieve steam treatment of the garments. After steam treatment, by controlling the first damper component 701 in the second position, the water mist sprayed by the spray device 6 can be used to quickly cool the inside of the drum, preventing users from being burned by the high temperature inside the drum when opening the door of the garment processing equipment to remove the garments.

[0134] This application embodiment also provides a control device, including a memory and a processor.
