Description

[0002] Existing heat pump drying equipment has the following air circulation channel: hot air superheated by the condenser in the heat pump circulation system is sent into the clothes processing drum, the humid air that has taken moisture from the clothes is sent back to the evaporator for dehumidification, the dehumidified air is heated again by the condenser and sent into the clothes processing drum.

[0003] In related technologies, in order to make reasonable use of the limited space between the clothes processing drum and the shell, the evaporator and condenser are integrated into a single unit.

[0048] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0049] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. 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.

[0050] 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.

[0051] In related technologies, heat pump drying equipment integrates the evaporator and condenser into a single component to make reasonable use of the limited space between the clothes handling drum and the shell. However, due to the limited space of the drying equipment, the volume of the two components cannot be increased, which results in the inability to effectively improve the dehumidification efficiency and further increase the drying efficiency.

[0052] To address the above technical problems, this embodiment proposes a drying system, which includes:

[0053] 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, the auxiliary air duct has a second air inlet and a second air outlet, the air duct wall of the main air duct has a first connecting port, the air duct wall of the auxiliary air duct has a second connecting port, and the connecting air duct connects the first connecting port and the second connecting port.

[0054] The main fan and the auxiliary fan are located in the main air duct and the auxiliary fan is located in the auxiliary air duct.

[0055] A heat pump assembly, comprising an evaporator and a condenser, both located within the main air duct, with the condenser positioned downstream of the evaporator in the direction of airflow.

[0056] A condensation device, which is installed in the auxiliary air duct, is used to condense the airflow in the auxiliary air duct;

[0057] The damper component is movably configured to have a first position that connects the airflow passage between the main air duct and the auxiliary air duct, and a second position that blocks the airflow passage between the main air duct and the auxiliary air duct. The damper component can be controlled to be in the first position or the second position.

[0058] This embodiment adds a connecting air duct between the main air duct equipped with two components and the auxiliary air duct equipped with a condenser device, and further provides a movable damper component. This allows the damper component to be controlled in the first position to connect the main air duct and the auxiliary air duct under high humidity and heat conditions during the drying and dehumidification stage. By further controlling the start of the auxiliary fan and the condenser device, the airflow in the clothes handling drum and the main air duct can enter the auxiliary air duct and be dehumidified by the condenser device in the auxiliary air duct, thereby increasing the dehumidification amount during the drying process and improving the dehumidification efficiency.

[0059] This embodiment can also reduce energy consumption and drying noise by controlling the damper component to be in the second position to block the passage of the main air duct and the auxiliary air duct during the low humidity and heat state of the drying and heating stage and the drying and dehumidification stage, and by controlling the auxiliary fan and the condenser to be turned off.

[0060] In this embodiment, during the drying and cooling stage, the passage of the main air duct and the auxiliary air duct can be blocked by controlling the damper component to be in the second position, and the fan and condenser can be started to accelerate the cooling rate inside the cylinder.

[0061] 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.

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

[0063] The air duct assembly includes a main air duct 31, an auxiliary air duct 32, and a connecting air duct 33. The main air duct 31 has a first air inlet 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.

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

[0065] The heat pump assembly includes an evaporator 4 and a condenser 5, both of which are 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.

[0066] 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.

[0067] 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, regulates the temperature and relative humidity inside the drum, and ensures 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.

[0068] The damper component 7 is movably configured, having a first position that connects the airflow passage between the main air duct 31 and the auxiliary air duct 32, and a second position that blocks the airflow passage between the main air duct 31 and the auxiliary air duct 32. The damper component 7 can be controlled to be in either the first or second position. The damper component 7 can be disposed at any position of the connecting air duct 33. In a preferred embodiment, the damper component 7 is disposed at the end of the connecting air duct 33 near the auxiliary air duct 32 or at the end of the connecting air duct 33 near the main air duct 31.

[0069] For example, the damper component 7 is disposed on the connecting duct 33, and includes a baffle and a motor for driving the baffle to move. The baffle includes a first end 71 and a second end 72 disposed opposite to each other. The connecting duct 33 includes a first sidewall and a second sidewall disposed opposite to each other. The first end 71 is movably connected to the first sidewall. When the damper component 7 is in the first position, the second end 72 is separated from the second sidewall to connect the airflow passage between the main duct 31 and the auxiliary duct 32. When the damper component 7 is in the second position, the second end 72 is sealed to the second sidewall to block the airflow passage between the main duct 31 and the auxiliary duct 32.

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

[0071] In one alternative implementation, the evaporator 4 is located downstream of the first connecting port 312 in the airflow direction within the main air duct 31. This avoids the evaporator 4 and condenser 5 affecting the airflow between the connecting air duct 33 and the main air duct 31, and also prevents the airflow in the main air duct 31 from being condensed by the evaporator 4 or heated by the condenser 5 before entering the connecting air duct 33, thereby reducing the condensing effect of the condensing device 6.

[0072] And / or, in the direction of airflow within the auxiliary air duct 32, the condenser 6 is located downstream of the second connecting port 322 to prevent airflow from the main air duct 31 from entering the clothes processing drum 1 through the auxiliary air duct 32 without being condensed by the condenser 6, thus reducing the dehumidification effect.

[0073] In one alternative implementation, the condensation device 6 is a water condensation device, which includes a spray section 61 and a water supply section 62. The spray section 61 is located in the auxiliary air duct 32, and the spray direction of the spray section 61 is towards 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.

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

[0077] This embodiment also 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:

[0078] A cavity is formed inside the shell, and a clothes processing cylinder 1 is provided inside the cavity. The clothes processing cylinder 1 has an air inlet and an air outlet. The first air outlet 311 and the second air outlet 321 are both connected to the air inlet, and the first air inlet and the second air inlet are both 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.

[0079] The locations of the air inlet and outlet are not explicitly defined. In one example, the opening of the garment processing drum 1 is sealed, and the air inlet is located at the seal. The air outlet is located at the bottom of the garment processing drum 1. This creates a long airflow path between the air inlet and outlet, allowing the airflow to penetrate the garments and ensuring a uniform drying effect.

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

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

[0082] This embodiment adjusts the auxiliary fan 22, condenser 6, and damper component 7 according to the clothing processing stage, thereby flexibly adjusting the airflow path between the auxiliary air duct 32, connecting air duct 33, and main air duct 31 based on the temperature and humidity conditions inside the drum, to further improve dehumidification efficiency and shorten drying time.

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

[0084] In one optional implementation, the garment processing equipment further includes a first temperature detection device and a second temperature detection device. The first temperature detection device 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.

[0085] The drying process of the garment processing equipment in this embodiment will be described in detail below.

[0086] The clothes drying process includes a drying heating stage, a drying dehumidification stage, and a drying cooling stage, executed sequentially. During the drying heating stage, the control device first starts the main fan 21 and the heat pump assembly. The airflow circulates between the clothes handling drum 1 and the main air duct 31. The auxiliary fan 22 and the water-cooled condenser are in the off state. At this time, the control damper component 7 is in the second position to prevent the airflow in the main fan 21 from entering the clothes handling drum 1 through the connecting air duct 33 and the auxiliary air duct 32 without being dehumidified and heated by the heat pump assembly, thus reducing the heating effect. (Refer to...) Figure 2 The airflow path diagram is shown.

[0087] When the air inlet temperature of the garment processing drum 1 reaches the third set temperature at the end of the drying and heating stage, the drying and heating stage ends and the drying and dehumidification stage begins.

[0088] During the drying and dehumidification stage, when the drum is in a high humidity and 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. After being cooled and dehumidified by the condenser 6, it is directly introduced into the clothes processing drum 1, thereby reducing the humidity inside the drum, reducing the load on the evaporator 4, and thus improving the dehumidification efficiency.

[0089] Under high humidity and heat conditions, the damper component 7 can be controlled to the first position. At this time, the airflow in the auxiliary air duct 32 is interconnected with the airflow in the main air duct 31. Part of the airflow in the auxiliary air duct 32 can enter the main air duct 31 through the connecting air duct 33 to increase the airflow of the evaporator 4 and improve the dehumidification efficiency of the evaporator 4. Alternatively, part of the airflow in the main air duct 31 can enter the auxiliary air duct 32 through the connecting air duct 33 to increase the airflow of the condenser 6 and improve the dehumidification efficiency of the condenser 6. (Refer to...) Figure 3 The airflow path diagram is shown. The airflow direction between the auxiliary air duct 32 and the main air duct 31 can be determined according to the rotational speed of the main fan 21 and the auxiliary fan 22. For example, when the rotational speed of the main fan 21 is greater than that of the auxiliary fan 22, the airflow in the main fan 21 enters the auxiliary air duct 32 through the connecting air duct 33. When the rotational speed of the auxiliary fan 22 is greater than that of the main fan 21, the airflow in the auxiliary air duct 32 enters the main air duct 31 through the connecting air duct 33. The airflow path between the main air duct 31 and the auxiliary air duct 32 can be flexibly adjusted according to the requirements of the wind speed of the main fan 21 and the auxiliary fan 22, and no specific limitation is made here.

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

[0091] 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 damper component 7 can be positioned in the second 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 2 The airflow path diagram.

[0092] Specifically, the outlet air temperature of the clothes processing drum under low humidity and heat conditions is higher than that under high humidity and heat conditions. For example, the low humidity and heat condition is when the outlet air temperature of the clothes processing drum 1 is greater than or equal to a first set temperature and less than a second set temperature, and the high humidity and heat condition is when the outlet air temperature of the clothes processing drum 1 is less than the first set temperature.

[0093] 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.

[0094] 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 fourth set temperature, the drying and cooling stage begins. At this time, the condenser 6 and auxiliary fan 22 are activated. The airflow in the auxiliary air duct 32 is cooled by the condenser 6 and then enters the clothes processing drum 1 to achieve rapid cooling. Furthermore, if the condenser 6 has a spray section 61, the water mist sprayed by the spray section 61 can also enter the clothes processing drum 1 with the airflow, further enhancing the cooling effect on the clothes processing drum 1. Additionally, the first damper component 7 is controlled to be in the second 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 being heated by the residual heat of the condenser 5 after entering the main air duct 31 via the connecting air duct 33, thus reducing the cooling effect on the clothes processing drum 1. Figure 4 The airflow path diagram.

[0095] 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.

[0096] This embodiment proposes a drying method for a garment processing device. The drying method is applied to the garment processing device described above, with reference to... Figure 6 The drying process flow chart shows the following steps:

[0097] S61. During the clothes drying process, determine the clothes drying stage or the humid and hot state of the clothes processing drum.

[0098] S62. Control the starting status of the auxiliary fan and condenser device and the position status of the damper components according to the clothes drying stage, or control the starting status of the auxiliary fan 22 and condenser device 6 and the position status of the damper components according to the humid and hot state of the clothes processing drum.

[0099] For example, the starting states of the auxiliary fan 22 and the condenser 6, and the position state of the damper component 7 are controlled according to the clothes drying stage, including: during the drying heating stage, both the condenser 6 and the auxiliary fan 22 are controlled to be in the off state, and the damper component 7 is controlled to be in the second position; and / or, during the drying dehumidification stage, the starting states of the auxiliary fan 22 and the condenser 6, and the position state of the damper component 7 are controlled according to the humid and hot state of the clothes processing drum 1; and / or, during the drying cooling stage, both the condenser 6 and the auxiliary fan 22 are controlled to be in the on state, and the damper component 7 is controlled to be in the second position.

[0100] For example, the activation status of the auxiliary fan 22 and the condenser 6, as well as the position status of the damper component, are controlled according to the humidity and heat state of the clothes processing drum 1. This includes: when the clothes processing drum 1 is in a high humidity and heat state, both the auxiliary fan 22 and the condenser 6 are activated, and the damper component 7 is in a first position; when the clothes processing drum 1 is in a low humidity and heat state, both the auxiliary fan 22 and the condenser 6 are deactivated, and the damper component 7 is in a second position; wherein, the outlet air temperature of the clothes processing drum in the low humidity and heat state is greater than that in the high humidity and heat state. For example, the low humidity and heat state is a state where the outlet air temperature of the clothes processing drum 1 is greater than or equal to a first set temperature and less than a second set temperature, and the high humidity and heat state is a state where the outlet air temperature of the clothes processing drum 1 is less than the first set temperature.

[0101] For example, during the drying and cooling stage, the main fan 21 is also controlled to be in the off state.
