A base device and clothing processing equipment

[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 202411220799.5, filed on August 30, 2024, and Chinese Patent Application No. 202422141755.5, filed on August 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of clothing processing technology, and in particular to a base device and clothing processing equipment. Background Technology

[0004] In related technologies, some garment processing equipment utilizes at least two heat exchange devices in conjunction to condense, dehumidify, and heat the airflow. Specifically, one heat exchange device performs a first heat exchange on the airflow entering the duct from the garment processing chamber, while another heat exchange device performs a second heat exchange on the airflow after the first heat exchange. However, the effectiveness of the heat exchange process still needs further improvement.

[0005] Summary of the Invention

[0006] In view of this, the embodiments of this application aim to provide a base device and clothing processing equipment that helps to prevent airflow from flowing directly through the gap between the bottom surface of the first heat exchange device and the bottom wall of the base, thereby improving the effect of airflow heat exchange processing.

[0007] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0008] In a first aspect, embodiments of this application provide a base device, including:

[0009] The base has an air duct, and the base has a first support surface and a second support surface, the second support surface being spaced apart from the bottom wall of the base;

[0010] A first heat exchange device is disposed in the air duct, and the first support surface is located on the bottom side of the first heat exchange device and is used to support the first heat exchange device.

[0011] The second heat exchange device is disposed in the air duct and is located downstream of the first heat exchange device along the airflow direction. The second support surface is located on the bottom side of the second heat exchange device and is used to support the second heat exchange device.

[0012] The first support surface is located at a position lower than the second support surface.

[0013] In some implementations, the height difference between the first support surface and the second support surface is 2mm to 10mm.

[0014] In some embodiments, the base includes a protrusion that protrudes from the upper surface of the bottom wall of the base, and the second heat exchange device is supported on the protrusion such that the bottom surface of the second heat exchange device is spaced apart from the bottom wall of the base.

[0015] In some embodiments, the protrusion includes a plurality of ribs, at least a portion of the top surface of the ribs defining the second support surface.

[0016] In some embodiments, the second heat exchange device extends along a first direction, and a plurality of the ribs are spaced apart along the first direction, the extension direction of the ribs intersecting the first direction.

[0017] In some embodiments, the base device further includes a baffle rib that protrudes from the upper surface of the bottom wall of the base and is disposed on the air outlet side of the second heat exchange device. The baffle rib extends along the length of the second heat exchange device to block the airflow flowing between the bottom surface of the second heat exchange device and the bottom wall of the base.

[0018] In some implementations, the top surface of the retaining rib is positioned higher than the second support surface.

[0019] In some embodiments, the base includes a first region and a drainage channel, the drainage channel being disposed on one side of the first region along a first direction of the base assembly, the drainage channel having a water outlet, the first heat exchange device and the second heat exchange device being arranged along a second direction, wherein the first direction and the second direction intersect, the first heat exchange device and the second heat exchange device are both at least partially located in the first region, and the bottom wall of the drainage channel is located lower than the bottom wall of the first region, so that water in the first region can flow into the drainage channel.

[0020] In some embodiments, the base device further includes a cover plate covering the drainage channel, one end of the first heat exchange device along a first direction of the base device is supported on the bottom wall of the first region, and the other end of the first heat exchange device along the first direction of the base device is supported on the cover plate.

[0021] In some implementations, the bottom wall of the first region includes a first portion, a flat portion, and a second portion, with a second heat exchange device located above the first portion. One end of the first heat exchange device is supported on the flat portion. The second portion extends downward at an angle from the flat portion toward the drainage channel, and is lower than both the first and flat portions, so that liquid in the first region is guided through the second portion to the drainage channel.

[0022] In some implementations, a stepped structure is formed at the junction of the second part and the first part.

[0023] In some embodiments, the first heat exchange device has a drain port, the cover plate has a through port, or the area of ​​the drainage channel not covered by the drainage channel forms a through port, the drain port being located above the cover plate so that the coolant discharged from the drain port can flow into the drainage channel through the through port.

[0024] In some embodiments, the first heat exchange device includes a fin assembly and liquid-cooled piping for the flow of coolant, and the first support surface is in contact with the bottom surface of the fin assembly.

[0025] In some embodiments, the liquid cooling pipeline includes an inlet and an outlet, the inlet and the outlet being located on the side of the fin assembly along a first direction of the base device and close to the drainage channel.

[0026] Secondly, embodiments of this application also provide a garment processing device, comprising:

[0027] The first cylindrical assembly has a first garment processing chamber;

[0028] And the base device in any of the above embodiments, wherein the air duct is connected to the first clothing processing chamber.

[0029] In some embodiments, the garment processing equipment includes a housing, a second tubular assembly, and a frame disposed within the housing. A base device is disposed on the frame, and the base device divides the space within the housing into at least a first space and a second space along the height direction. The first tubular assembly is disposed in the first space, and the second tubular assembly is disposed in the second space.

[0030] In some implementations, the first cylindrical assembly is positioned higher than the second cylindrical assembly.

[0031] In the base device of this application embodiment, the first support surface is located lower than the second support surface. That is, the bottom surface of the first heat exchange device is located lower than the bottom surface of the second heat exchange device. This, to a certain extent, prevents the airflow from directly flowing through the gap between the bottom surface of the first heat exchange device and the bottom wall of the base into the second heat exchange device. This forces the airflow to undergo heat exchange in the first heat exchange device before entering the second heat exchange device, thereby improving the heat exchange effect of the airflow.

[0046] Please refer to Figures 3 to 10. This application embodiment provides a base device 10, including a base 11, a first heat exchange device 12, and a second heat exchange device 13.

[0047] The base 11 has an air duct for airflow. Please refer to Figures 3, 6, 8, 9 and 10. The arrows in Figures 3, 6, 8, 9 and 10 indicate the flow path of the airflow in the air duct.

[0048] Please refer to Figure 4. The base 11 has a first support surface 111 and a second support surface 112. The second support surface 112 is spaced apart from the bottom wall 11a of the base 11.

[0049] It should be noted that the first support surface 111 can be a continuous surface or an abstract surface defined by multiple structures, and the second support surface 112 can be a continuous surface or an abstract surface defined by multiple structures.

[0050] The first heat exchange device 12 is disposed in the air duct, and the first support surface 111 is located on the bottom side of the first heat exchange device 12 and is used to support the first heat exchange device 12. That is, the first heat exchange device 12 is placed on the first support surface 111.

[0051] In some embodiments, the first heat exchange device 12 has a first bottom surface 12b that contacts the first support surface 111, and the two are substantially at the same height. It should be noted that the first bottom surface 12b can be a continuous surface or an abstract surface defined by multiple structures of the first heat exchange device 12.

[0052] The second heat exchange device 13 is located in the air duct and downstream of the first heat exchange device 12 along the airflow direction. The second support surface 112 is located on the bottom side of the second heat exchange device 13 and is used to support the second heat exchange device 13. That is, the second heat exchange device 13 is placed on the second support surface 112.

[0053] In some embodiments, the second heat exchange device 13 has a second bottom surface 13b that contacts the second support surface 112, and the two are substantially at the same height. It should be noted that the second bottom surface 13b can be a continuous surface or an abstract surface defined by multiple structures of the second heat exchange device 13.

[0054] It should be noted that the heat exchange device is used to exchange heat with the airflow passing through the air duct, thereby achieving condensation dehumidification or heating of the airflow.

[0055] The first support surface 111 is located below the second support surface 112. That is, the first bottom surface 12b of the first heat exchange device 12 is located below the second bottom surface 13b of the second heat exchange device 13.

[0056] The base device 10 provided in this application embodiment requires the airflow to pass through the first heat exchange device 12 before flowing to the second heat exchange device 13 when the airflow passes through the air duct. Because the first support surface 111 is lower than the second support surface 112, a height difference exists between the first and second bottom surfaces, causing the airflow to pass through the first heat exchange device 12 before passing through the second heat exchange device 13. Although there is a gap between the second bottom surface 13b of the second heat exchange device 13 and the bottom wall 11a of the base, the first bottom surface 12b, being lower than the second bottom surface 13b, provides some shielding effect on this gap, allowing the airflow to pass through the first heat exchange device 12 before passing through the second heat exchange device 13. In other words, when the airflow enters the air duct and undergoes heat exchange, it passes through the first heat exchange device 12 before passing through the second heat exchange device 13, maximizing the heat exchange effect and improving the heat exchange efficiency.

[0057] In some embodiments, the first heat exchange device 12 can be a heat-absorbing device, and the second heat exchange device 13 can be a heat-releasing device. In other embodiments, both the first heat exchange device 12 and the second heat exchange device 13 can be heat-absorbing devices. In still other embodiments, both the first heat exchange device 12 and the second heat exchange device 13 can be heat-releasing devices.

[0058] A heat absorption device is a device that absorbs heat from an airflow and cools it down. During the cooling process, water vapor in the airflow is condensed into water, thus achieving the function of condensation and dehumidification of the airflow.

[0059] A heat-generating device refers to a device that heats the airflow.

[0060] In this embodiment, the first heat exchange device 12 and the second heat exchange device 13 described above are both used as heat absorption devices. In this embodiment, the first heat exchange device 12 and the second heat exchange device are used to condense and dehumidify the airflow. The airflow entering the duct first flows through the first heat exchange device 12 and then through the second heat exchange device 13. This allows the airflow to undergo double condensation and cooling, improving the condensation and dehumidification effect of the airflow.

[0061] Please refer to Figure 4. The base device 10 also includes a third heat exchange device 14, which is located downstream of the second heat exchange device 13 along the airflow direction. The third heat exchange device 14 is used to heat the airflow.

[0062] Referring to Figure 1, this application also provides a garment processing device, including a first cylindrical assembly 20 and a base device 10 according to any embodiment of this application. The first cylindrical assembly 20 has a first garment processing chamber, and an air duct communicates with the first garment processing chamber. The first cylindrical assembly 20 is used to care for garments.

[0063] Clothing processing equipment can at least be used to dry clothes. The specific type of clothing equipment is not limited here. For example, it can be a dryer or a washer-dryer combo.

[0064] In some embodiments, the clothing handling equipment includes a heat pump system, which includes components such as a compressor, evaporator, and condenser, with the compressor, condenser, and evaporator connected in series in a refrigerant circuit.

[0065] The working principle of a heat pump system is as follows: The compressor draws in low-pressure gaseous refrigerant, compresses it, and discharges it as high-pressure gas. The discharged high-pressure gaseous refrigerant enters the condenser, where it is cooled by the ambient air around the condenser and condenses into a high-pressure liquid (simultaneously transferring heat to the surrounding air). In other words, the air around the condenser is heated. The high-pressure liquid refrigerant flows through a throttling device to reduce pressure, becoming a low-pressure, low-temperature gas-liquid two-phase mixture. This mixture enters the evaporator, where the liquid refrigerant evaporates and cools (simultaneously absorbing heat from the surrounding air). In other words, the air around the evaporator is cooled. The refrigerant is then drawn back into the compressor and pressurized. This cycle repeats continuously, achieving heat exchange.

[0066] In some embodiments, the evaporator may serve as the first heat exchange device 12 and / or the second heat exchange device 13 described above. The condenser may serve as the third heat exchange device 14 described above.

[0067] In this embodiment, the drying principle of the clothing processing equipment is as follows: the hot and humid airflow discharged from the first clothing processing chamber 21 enters the air duct, undergoes the first condensation and dehumidification by the first heat exchange device 12, and then undergoes the second condensation and dehumidification by the second heat exchange device 13. The airflow after condensation and dehumidification is heated by the third heat exchange device 14, and the heated airflow returns to the first clothing processing chamber 21 through the air duct. This cycle is repeated to achieve continuous drying of clothing.

[0068] The specific types of the first heat exchange device 12 and the second heat exchange device 13 are not limited. For example, in some embodiments, both the first heat exchange device 12 and the second heat exchange device 13 serve as evaporators in the aforementioned heat pump system; that is, the heat pump system can be configured with two evaporators. In other embodiments, one of the first heat exchange device 12 and the second heat exchange device 13 is the evaporator in the aforementioned heat pump system. For example, the first heat exchange device 12 is an evaporator, and the second heat exchange device 13 is a liquid cooling device for circulating coolant; or, the second heat exchange device 13 is an evaporator, and the first heat exchange device 12 is a liquid cooling device. In still other embodiments, both the first heat exchange device 12 and the second heat exchange device 13 can be liquid cooling devices.

[0069] Specifically, a liquid cooling device for circulating coolant refers to a device into which coolant can be introduced. As the coolant flows through the liquid cooling device, it helps to maintain a relatively low temperature on the outer surface of the liquid cooling device. When the airflow in the duct flows over the outer surface of the liquid cooling device, heat exchange occurs between the liquid cooling device and the airflow. The liquid cooling device absorbs the heat from the airflow and transfers the heat to the coolant in the liquid cooling device. The coolant heats up, while the airflow temperature drops. The water vapor in the airflow reaches saturation and condenses into condensate on the outer surface of the liquid cooling device, thereby achieving the purpose of condensation and dehumidification of the airflow by the liquid cooling device.

[0070] The specific type of coolant is not limited. In some embodiments, the coolant is water, such as tap water or salt water. In other embodiments, the coolant may be other liquids.

[0071] For example, the first heat exchange device 12 is a liquid cooling device, the second heat exchange device 13 is an evaporator, and the third heat exchange device 14 is a condenser. In this embodiment, the first heat exchange device 12 performs a first condensation and dehumidification on the airflow entering the air duct, reducing the temperature and humidity of the airflow and intercepting some impurities such as lint. After the first condensation and dehumidification, the airflow flows through the second heat exchange device 13 for a second condensation and dehumidification, further condensing and dehumidifying the airflow. Since the airflow has already undergone a first condensation and dehumidification before flowing through the second heat exchange device 13, it helps to reduce the evaporation temperature of the evaporator while ensuring the condensation and dehumidification effect on the airflow, thereby reducing the power consumption of the heat pump system. It is understood that in other embodiments, the first heat exchange device 12 can be an evaporator or a liquid cooling device for circulating coolant, the second heat exchange device 13 can be a condenser, and the third heat exchange device 14 can be an electric heating element.

[0072] The specific type of coolant is not limited. In some embodiments, the coolant is water, such as tap water or salt water. In other embodiments, the coolant may be other liquids.

[0073] In this embodiment, the drying principle of the clothing processing equipment is as follows: the hot and humid airflow discharged from the first clothing processing chamber 21 is condensed and dehumidified by the first heat exchange device 12. The condensed and dehumidified airflow is then heated for the first time by the second heat exchange device 13. After the first heating, the airflow is heated for the second time by the third heat exchange device 13. The heated airflow then returns to the first clothing processing chamber 21 through the air duct, and this cycle is repeated to achieve continuous drying of the clothing. In this embodiment, the airflow undergoes two heating cycles, resulting in a higher temperature of the airflow returning to the first clothing processing chamber 21, which helps to improve the drying effect.

[0074] It is understood that, in this embodiment, the third heat exchange device 14 may not be provided.

[0075] In other embodiments, the third heat exchange device 14 may also be an electric heating element.

[0076] It should be noted that the low-temperature dry airflow is relative to the humid and hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the humid and hot airflow. In the embodiments of this application, the low temperature can be room temperature.

[0077] In some embodiments, the garment handling equipment includes a housing, a second cylinder assembly 30, and a frame 40 disposed within the housing.

[0078] The frame 40 is the main support structure, used for the fixed installation and support of other components of the garment processing equipment.

[0079] The base device 10 is located on the frame 40, and the base device 10 and its load transmit the force to the frame 40.

[0080] In some embodiments, referring to Figure 2, the frame 40 includes at least four columns 41, which extend along the height direction. In a horizontal projection, the four columns 41 are distributed at the four vertices of the quadrilateral.

[0081] In this embodiment of the application, the height direction is the top-bottom direction in Figures 2 and 4, that is, it includes both the direction from top to bottom and the direction from bottom to top.

[0082] For example, the base device 10 can be connected to each of the four columns 41 described above. The base device 10 is located within the area defined by the four columns 41.

[0083] The base device 10 divides the space inside the box into at least a first space and a second space along the height direction. The first cylindrical assembly 20 is disposed in the first space, and the second cylindrical assembly 30 is disposed in the second space.

[0084] In some embodiments, the first garment processing chamber 21 is at least capable of drying garments. The second drum assembly 30 has a second garment processing chamber 31, which is at least capable of washing garments.

[0085] In some embodiments, the first space is located above the second space, that is, the position of the first cylindrical assembly 20 is higher than the position of the second cylindrical assembly 30. In other embodiments, the first space may also be located below the second space, that is, the position of the second cylindrical assembly 30 is higher than the position of the first cylindrical assembly 20.

[0086] In some embodiments, the height difference h1 between the first support surface 111 and the second support surface 112 (see Figure 5) is 2mm to 10mm, i.e., 2mm ≤ h1 ≤ 10mm. Within this range, the height difference between the first support surface 111 and the second support surface 112 maintains the obstruction effect of the first heat exchange device 12 on the airflow, ensuring that the airflow passes through the first heat exchange device 12 before entering the second heat exchange device 13, while also preventing the base device 10 from being excessively tall in the height direction of the clothing processing equipment.

[0087] For example, the height difference h1 between the first support surface 111 and the second support surface 112 is 5 mm.

[0088] In some embodiments, referring to Figures 3 and 4, the base 11 includes a bottom shell 117 and a top cover 118. The top cover 118 is disposed on the top side of the bottom shell 117. The top surface of the first heat exchange device 12 facing the top cover is lower than the top surface 13a of the second heat exchange device 13. Thus, a first clearance space is formed between the top surface 12a of the first heat exchange device 12 and the top cover 118, which allows other components to be installed, thus helping to make the base device 10 compact.

[0089] It is understood that the top surface 12a of the first heat exchange device 12 refers to the surface of the first heat exchange device 12 where the structure closest to the top cover 118 is located. It can be a continuous surface or an abstract surface defined by multiple structures of the first heat exchange device 12. The top surface 13a of the second heat exchange device 13 refers to the surface of the second heat exchange device 13 where the structure closest to the top cover 118 is located. It can be a continuous surface or an abstract surface defined by multiple structures of the second heat exchange device 13.

[0090] In some embodiments, the height difference h2 between the top surface 13a of the second heat exchange device 13 and the top surface 12a of the first heat exchange device 12 (see Figure 5) is 3mm to 15mm, i.e., 3mm ≤ h2 ≤ 15mm. This range ensures that a suitable first clearance space is formed between the top surface 12a of the first heat exchange device and the top cover 118, which satisfies the installation requirements without reducing the height dimension of the first heat exchange device 12 due to a large height difference (taking the position of the top surface 13a of the second heat exchange device 13 as a reference; if the height difference is too large, it means that the height of the first heat exchange device 12 is too low, affecting the heat exchange effect between the first heat exchange device 12 and the airflow).

[0091] For example, the height difference h2 between the top surface 13a of the second heat exchange device 13 and the top surface 12a of the first heat exchange device 12 is 5 mm.

[0092] In some embodiments, the base device 10 includes a functional component disposed between the top surface 12a of the first heat exchange device 12 and the top cover 118. That is, the functional component is disposed in the first clearance space.

[0093] It should be noted that functional components refer to components that can provide functions other than heat exchange.

[0094] In some embodiments, referring to FIG5, at least a portion of the top cover 118 protrudes upward to form a second clearance space 118a below the top cover 118, and the functional component is at least partially disposed within the second clearance space 118a. That is, the functional component is disposed within the clearance space formed by the first clearance space and the second clearance space 118a.

[0095] In some embodiments, the dimension h3 of the second clearance space 118a along the height direction is 1mm to 4.5mm, i.e., 1mm ≤ h3 ≤ 4.5mm. This range allows the top cover 118 to not protrude a large dimension upwards while still providing a second clearance space 118a to accommodate the spray device 17.

[0096] For example, the second clearance space 118a has a height dimension h3 of 1.5 mm. In some embodiments, referring to FIG. 4, the functional component includes a spray device 17. Referring to FIG. 5, the spray device 17 has at least one spray nozzle 172. The spray nozzle 172 is used to spray liquid toward at least one of the second heat exchange device 13, the first heat exchange device 12, and the bottom wall 117a of the bottom shell 117. That is, the spray device 17 is installed in the clearance space formed between the top surface of the first heat exchange device 12 and the top cover 118.

[0097] Understandably, in some embodiments, the spray nozzle 172 can spray liquid toward the second heat exchange device 13 to remove impurities such as lint adhering to the surface of the second heat exchange device 13. In some embodiments, the spray nozzle can spray liquid toward the first heat exchange device 12 to remove impurities such as lint adhering to the surface of the first heat exchange device 12. In some embodiments, the spray nozzle can spray liquid toward the bottom wall 117a of the bottom shell 117 to clean the bottom wall 117a of the bottom shell 117. In some embodiments, the spray nozzle 172 can spray liquid toward any two of the first heat exchange device 12, the second heat exchange device 13, and the bottom wall 117a of the bottom shell 117. In some embodiments, the spray nozzle can spray liquid toward all of the second heat exchange device 13, the first heat exchange device 12, and the bottom wall 117a of the bottom shell 117.

[0098] It is understood that the bottom wall 117a of the bottom shell 117 in this embodiment is the same as the bottom wall 11a of the base 11.

[0099] It should be noted that in embodiments where the spray nozzle 172 can spray liquid toward the second heat exchange device 13, the second heat exchange device 13 is a liquid cooling device or evaporator for circulating coolant.

[0100] Furthermore, the liquid sprayed from the spray nozzle 172 can directly contact the airflow, which helps to cool the airflow and thus facilitates condensation and dehumidification. It should be noted that in this embodiment, the airflow may not flow through the spray device 17.

[0101] In some embodiments, referring to Figure 7, the spray device 17 extends along a first direction, and there are multiple spray nozzles 172 arranged along the first direction. The spray nozzles 172 are located above the windward side 123 of the first heat exchange device 12, and are used to spray liquid onto the windward side 123. In this embodiment, the liquid sprayed from the spray nozzles 172 flows from top to bottom, that is, the liquid flows from the top of the windward side 123 to the bottom of the windward side 123. At this time, the liquid is basically not sprayed obliquely onto the first heat exchange device 12 along the airflow direction. Therefore, the liquid will not wash the impurities attached to the windward side 123 into the interior of the first heat exchange device 12, which is conducive to the removal and cleaning of impurities.

[0102] It should be noted that the windward surface 123 of the first heat exchange device 12 refers to the surface of the first heat exchange device 12 that first contacts the airflow when it flows through it. The windward surface 123 is not a continuous surface; the airflow needs to pass directly through the windward surface 123.

[0103] For example, as shown in Figures 8 and 9, the base 11 includes a protrusion that protrudes from the upper surface of the bottom wall 11a of the base. The second heat exchange device 13 is supported on the protrusion so that the bottom surface of the second heat exchange device 13 is spaced apart from the bottom wall 11a of the base 11, that is, the second bottom surface 13b is spaced apart from the bottom wall 11a of the base 11.

[0104] In this embodiment, the top surface of the protrusion defines the aforementioned second support surface 112. This arrangement allows the liquid generated during the heat exchange process of the second heat exchange device 13 to drain into the gap between the second bottom surface 13b of the second heat exchange device 13 and the bottom wall 11a of the base 11, facilitating the timely discharge of the liquid from this gap and reducing the risk of the lower part of the second heat exchange device 13 being soaked by the precipitated liquid.

[0105] It should be noted that the specific shape of the protrusion is not limited, as long as it can create a gap between the second bottom surface 13b of the second heat exchange device 13 and the bottom wall 11a of the base 11.

[0106] For example, as shown in FIG8, the protrusion includes a plurality of ribs 114, and the top surface of at least a portion of the ribs 114 defines a second support surface 112, that is, the plurality of ribs 114 jointly support the second heat exchange device 13. In some embodiments, the second heat exchange device 13 extends along a first direction, and the plurality of ribs 114 are spaced apart along the first direction, and the spacing between two adjacent ribs 114 can guide the liquid precipitated from the second heat exchange device 13.

[0107] In some embodiments, the extending direction of the rib 114 intersects with the first direction. That is, the guiding direction of the rib 114 for water flow intersects with the first direction.

[0108] It should be noted that the extension direction of the rib 114 refers to the direction shown by the straight line connecting the start and end points of the rib 114.

[0109] For example, as shown in FIG6, the base device 10 further includes a baffle 15, which protrudes from the upper surface of the bottom wall 11a of the base 11 and is disposed on the air outlet side of the second heat exchange device 13. The baffle 15 extends along the length direction of the second heat exchange device 13 and is used to block the airflow flowing between the bottom surface of the second heat exchange device 13 and the bottom wall 11a of the base 11.

[0110] In this embodiment, the baffle 15 can block the airflow between the bottom surface of the second heat exchange device 13 and the bottom wall 11a of the base 11, which can reduce the probability that the airflow will directly reach the third heat exchange device 14 without passing through the heat exchange function of the second heat exchange device 13, thereby helping to improve the heat exchange effect of the airflow and improve the drying effect.

[0111] In some embodiments, the second heat exchange device 13 extends along a first direction, and the first heat exchange device 12 and the second heat exchange device 13 are arranged along a second direction, wherein the first direction and the second direction intersect, for example, the first direction and the second direction are substantially perpendicular.

[0112] It should be noted that the specific directions of the first and second directions are not limited. For example, the first direction is the direction shown in Figures 3, 6, 8, 9 and 10, and the second direction is the direction shown in Figures 3, 6, 8, 9 and 10.

[0113] For example, as shown in FIG6, the retaining rib 15 extends along a first direction.

[0114] For example, one end of the protruding rib 114 is connected to the retaining rib 15, and the other end extends toward one side in the first direction.

[0115] In some embodiments, the top surface of the baffle 15 is positioned higher than the second support surface 112, so that the baffle 15 can better prevent airflow from directly reaching the third heat exchange device 14 without passing through the heat exchange function of the second heat exchange device 13.

[0116] In some embodiments, the base 11 includes a first region 115 and a drainage channel 116. The drainage channel 116 is located on one side of the first region 115 along a first direction of the base device 10 and has an outlet. The first heat exchange device 12 and the second heat exchange device 13 are arranged along a second direction, wherein the first direction and the second direction intersect.

[0117] The first heat exchange device 12 and the second heat exchange device 13 are both located at least partially in the first region 115, and the bottom wall 116a of the drain channel 116 is located below the bottom wall 115a of the first region 115, so that the liquid in the first region 115 can flow to the drain channel 116.

[0118] In this example, the liquid generated during the heat exchange process between the first heat exchange device 12 and the second heat exchange device 13 is discharged to the first region 115, and the liquid in the first region 115 can be discharged from the base device 10 through the drainage channel 116.

[0119] In some embodiments, the first direction is the left-right direction of the garment processing equipment. The first heat exchange device 12 and the second heat exchange device 13 are arranged along the front and back of the garment processing equipment.

[0120] In some embodiments, as shown in Figures 5 and 8, the base device 10 further includes a cover plate 16. The cover plate 16 covers the drainage channel 116. By providing the cover plate 16 in the drainage channel 116, it is possible to minimize the formation of water vapor in the drainage channel 116 under the negative pressure of the airflow and prevent it from entering the downstream of the air duct, thereby minimizing the entry of water vapor into the first clothing processing chamber 21.

[0121] As shown in Figure 5, one end of the first heat exchange device 12 along the first direction of the base device 10 is supported on the bottom wall 115a of the first region 115, and the other end of the first heat exchange device 12 along the first direction of the base device 10 is supported on the cover plate 16.

[0122] In this embodiment, the portion of the cover plate 16 that contacts the first heat exchange device 12 forms part of the first support surface 111. Thus, the cover plate 16 also provides support for the first heat exchange device 12, helping to improve the installation stability of the first heat exchange device 12. Furthermore, by fully utilizing the space above the drainage channel 116, it helps to reduce the space occupied by the first heat exchange device 12 in the first region 115 in the first direction, resulting in a more compact structure for the base device 10.

[0123] In some embodiments, referring to FIG6, the first heat exchange device 12 has a drain port 1212, and the cover plate 16 has a through port 161. Alternatively, the area of ​​the drainage channel 116 not covered by the cover plate 16 forms the through port 161. The drain port 1212 is located above the cover plate 16 so that the coolant discharged from the drain port 1212 can flow into the drainage channel 116 through the through port 161. In this way, the coolant of the first heat exchange device 12 can be directly discharged into the drainage channel 116 through the through port 161 without passing through the first area 115, thereby improving the drainage effect of the base device 10.

[0124] It should be noted that the cover plate 16 has a liquid outlet 161, and the shape of the liquid outlet 161 is independently defined by the cover plate 16. The area not covered by the cover plate 16 refers to the area where the liquid outlet 161 is located outside the overall outline of the cover plate 16. For example, if the length of the drain channel 116 is 100cm, the length of the cover plate 16 is 80cm, and there is a 20cm gap between the end of the cover plate 16 and the end of the drain channel 116, then this gap constitutes the aforementioned liquid outlet 161.

[0125] In some embodiments, in the horizontal projection, the drain port 1212 is located within the projection range of the through port 161. Thus, along the height direction of the garment processing equipment, the coolant discharged from the drain port 1212 can directly flow through the through port 161 under the action of gravity and enter the drainage channel 116, which helps to improve drainage efficiency. Moreover, there is no need to arrange drainage pipes from the drain port 1212 to the through port 161, which helps to save layout space and layout costs.

[0126] For example, referring to Figures 8, 9, and 10, the bottom wall 115a of the first region 115 includes a first portion 1151, a flattened portion 1152, and a second portion 1153. The second heat exchange device 13 is located above the first portion 1151, and one end of the first heat exchange device 12 is supported on the flattened portion 1152. In this embodiment, the flattened portion 1152 forms part of the first support surface 111.

[0127] The second part 1153 extends downward from the flat part 1152 toward the drainage channel 116. The second part 1153 is lower than the first part 1151 and lower than the flat part 1152, so that the liquid in the first region 115 is guided through the second part 1153 to the drainage channel 116.

[0128] In this embodiment, the second part 1153 mainly serves as a drain and guide. The liquid generated during the heat exchange process between the second heat exchange device 13 and the airflow passes through the first part 1151 and flows into the second part 1153, and then is guided through the second part 1153 to the drain channel 116. The liquid generated during the heat exchange process between the first heat exchange device 12 and the airflow is directly guided through the second part 1153 to the drain channel 116. Since the second part 1153 is located lower than the first part 1151, it helps to reduce the probability that the liquid in the second part 1153 will flow downstream along the upper surface of the bottom wall 115a of the first region 115 under the carrying effect of the airflow.

[0129] In some embodiments, a plurality of ribs 114 are provided on the first portion 1151, and the plurality of ribs 114 are arranged at intervals along a first direction, the extending direction of the ribs 114 intersects the first direction, and the interval between the plurality of ribs 114 forms a flow channel for the liquid in the first portion 1151.

[0130] In some embodiments, one end of the rib 114 is connected to the baffle 15, and the other end extends toward the first direction and toward the side where the drainage channel 16 is located, so that the water in the first part 1151 can be quickly discharged to the second part 1153 along the guide channel.

[0131] In some embodiments, the first bottom surface 12b of the first heat exchange device 12 is located higher than the junction of the first part 1151 and the second part 1153. On the one hand, this reduces the probability that the first heat exchange device 12 will block the liquid flowing from the first part 1151 to the second part 1153. On the other hand, it also reduces the probability that the liquid flowing from the first part 1151 to the second part 1153 will scour the first heat exchange device 12.

[0132] For example, as shown in Figures 8 to 10, a stepped structure 1154 is formed at the junction of the second part 1153 and the first part 1151, so that the liquid in the second part 1153 cannot flow back to the first part 1151 with the airflow. The stepped structure 1154 can better block the liquid in the second part 1153, improve the drainage effect of the base device 10, and further reduce the probability that the liquid in the second part 1153 will flow downstream of the air duct along the upper surface of the bottom wall 115a of the first region 115 under the carrying effect of the airflow.

[0133] In some embodiments, the first heat exchange device 12 includes a fin assembly 122 and a liquid-cooled pipe 121 for flowing coolant, and the first support surface 111 is in contact with the bottom surface of the fin assembly 122. That is, the first bottom surface 12b of the first heat exchange device 12 is the bottom surface of the fin assembly 122.

[0134] In some embodiments, the liquid cooling pipeline 121 includes a liquid inlet 1211 and a liquid outlet 1212, which are located on the side of the fin assembly 122 along the first direction of the base device 10 and close to the drainage channel 116. The liquid inlet 1211 and the liquid outlet 1212 being located on the same side of the fin assembly 122 facilitates pipeline layout.

[0135] The inlet 1211 needs to be connected to the water supply component, and the area above the drain channel 116 provides sufficient space for the inlet 1211 and the water supply component. The drain outlet 1212 is located on the side close to the drain channel 116 to facilitate the discharge of coolant from the liquid cooling pipe 121, allowing the coolant in the liquid cooling pipe 121 to be discharged directly to the drain channel 116 without passing through the first area 115, so that the coolant can be discharged in a timely manner.

[0136] In some embodiments, the position of the liquid inlet 1211 is higher than the position of the liquid outlet 1212. The height difference between the liquid inlet 1211 and the liquid outlet 1212 allows the liquid coolant to flow under its own gravity, thereby reducing the pressure requirement of the coolant flowing into the liquid inlet 1211.
