[0002] This application is based on and claims priority to Chinese Patent Application No. 202410486417.7, filed on April 22, 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 more particularly to a clothing processing device. Background Technology

[0004] In related technologies, garment processing equipment is equipped with a drying tunnel assembly to house a condensation dehumidification device and heating elements. This drying tunnel assembly is positioned above the drum assembly and has an air duct. After the dry hot airflow exchanges heat and moisture with the garments, the resulting humid hot airflow leaves the drum assembly and flows towards the upward air duct. However, this humid hot airflow needs to change direction after entering the air duct, which easily creates turbulence at the air inlet, causing it to diffuse and fail to concentrate its flow towards the condensation dehumidification device, thus affecting drying efficiency. Furthermore, the airflow tends to stagnate at the air inlet, accumulating lint and debris. This not only contaminates the air duct but also causes blockages, hindering the airflow from the drum assembly into the air duct. Summary of the Invention

A communication port is formed at the junction of the first installation area and the second installation area.

[0010] A flow guide, disposed within the second installation area and located at the air inlet, is used to guide the airflow from the air inlet to the connecting port.

[0011] In some implementations, the second installation area is located behind the first installation area, and the guide has an arc-shaped guide surface adapted to deflect the upward airflow at the air inlet forward to the connecting port.

[0018] In some embodiments, the garment processing equipment further includes a filter device, at least a portion of which is disposed in the first mounting area for filtering airflow passing through the filter device, the filter device having an air inlet that is connected to the communication port.

[0019] In some embodiments, the drying duct assembly includes a bottom cover and a cover plate assembly, the air inlet is disposed on the bottom cover, and the cover plate assembly is connected to the bottom cover along the height direction of the garment processing equipment and defines the air duct.

[0033] This application provides a garment processing device 1. Please refer to Figure 1. The garment processing device 1 includes a drum assembly 10, a drying tunnel assembly 11, and a flow guide 12.

[0034] It should be noted that the clothing processing equipment 1 can be a drum washing machine with drying function, or a washer-dryer combo, etc., and there are no restrictions here.

[0035] The tube assembly 10 has a clothing processing chamber 10a, an air inlet and an air outlet 10b communicating with the clothing processing chamber 10a.

[0036] Exemplarily, the drum assembly 10 includes an inner drum and an outer drum, with the outer drum fitted over the inner drum. The outer drum holds water for washing clothes, and the inner drum holds the clothes. The space inside the inner drum defines a clothes handling chamber 10a. Exemplarily, the inner and outer drums are arranged coaxially, with holes on the side wall of the inner drum. Water from the outer drum can enter the inner drum through the holes to wash the clothes in the clothes handling chamber 10a. In this embodiment, the inner drum can also be referred to as a perforated inner drum. Of course, in some other embodiments, the inner drum can also hold water and clothes on its own, with the outer drum fitted over the inner drum. In this embodiment, the inner drum can also be referred to as a non-perforated inner drum. In still some embodiments, the drum assembly only has an inner drum and no outer drum. The inner drum holds water and clothes on its own. In this embodiment, the inner drum can also be referred to as a non-perforated inner drum.

[0037] The garment processing chamber 10a is connected to the air inlet and the air outlet 10b. When drying the clothes in the garment processing chamber 10a, the dry hot air enters the garment processing chamber 10a through the air inlet to exchange heat and moisture with the clothes in the garment processing chamber 10a. The hot and humid air generated after the heat and moisture exchange leaves the garment processing chamber 10a through the air outlet 10b.

[0038] The drying tunnel assembly 11 has an air duct 11b, which connects an air inlet and an air outlet 10b to form a circulating air duct 11b with the clothing processing chamber 10a. The air duct 11b includes a first mounting area 11f and a second mounting area 11g. An air inlet 11a is provided on the bottom wall of the second mounting area 11g.

[0039] Specifically, after the hot and humid airflow leaves the clothing processing chamber 10a through the air outlet 10b, it enters the air duct 11b through the air inlet 11a. After condensation and dehumidification in the air duct 11b, it forms a low-temperature dry airflow. After being heated, it forms a dry hot airflow. The dry hot airflow then leaves the air duct 11b and enters the clothing processing chamber 10a through the air inlet.

[0040] The following is a brief description of the drying process and principle of the clothing processing device 1 in this embodiment.

[0041] When the clothing processing equipment 1 dries clothes, the hot dry airflow leaves from the air duct 11b and enters the clothing processing chamber 10a through the air inlet. In the clothing processing chamber 10a, the hot dry airflow flows over the surface of the wet clothes, exchanges heat and moisture with the clothes, absorbs the moisture from the clothes, and becomes a humid hot airflow. The humid hot airflow enters the air inlet 11a of the air duct 11b through the air outlet 10b, and flows sequentially through the condenser and dehumidifier and the heating element. During the flow through the condenser and dehumidifier, the water vapor in the humid hot airflow is cooled and condenses into water droplets. After being condensed and dehumidified by the condenser and dehumidifier, the humid hot airflow becomes a low-temperature dry airflow. When the low-temperature dry airflow passes through the heating element, it is heated into a dry hot airflow. The dry hot airflow re-enters the clothing processing chamber 10a through the air duct 11b and the air inlet, and so on, to achieve continuous and efficient drying of clothes.

[0042] 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.

[0043] It is understandable that the air duct 11b is defined by the internal structure of the drying duct assembly 11, and the air inlet 11a is located on the bottom wall of the second mounting area 11g. That is, the drying duct assembly 11 is connected to the air outlet 10b of the clothing processing chamber 10a through the bottom wall of the second mounting area 11g. The airflow from the air outlet 10b of the cylinder assembly 10 to the air inlet 11a generally has a downward flow trend.

[0044] For example, the drying tunnel assembly 11 can be disposed on the top side of the cylinder assembly 10, and the air inlet 11a can be disposed directly above the air outlet 10b, so that the airflow flowing out of the air outlet 10b is concentrated and flows upward to the air inlet 11a.

[0045] Air inlet 11a is located in the second installation area 11g. That is, during the flow of air in the air duct 11b, the air first enters the second installation area 11g through air inlet 11a, and then flows to the first installation area 11f. The first installation area 11f can be equipped with a condensation and dehumidification component and a heating component, so that the airflow is condensed, dehumidified and heated when it flows from the second installation area 11g into the first installation area 11f.

[0046] The first installation area 11f and the second installation area 11g are interconnected. A connection port 11h is formed at the junction of the first installation area 11f and the second installation area 11g. That is, the airflow from the second installation area 11g flows to the first installation area 11f through the connection port 11h.

[0047] The air guide 12 is disposed in the second installation area 11g and located at the air inlet 11a, and is used to guide the airflow of the air inlet 11a to the connecting port 11h.

[0048] The flow guide 12 is a structure with a flow guiding function. Specifically, the flow guide 12 can guide the airflow at the air inlet 11a, so that the airflow at the air inlet 11a flows along a predetermined trajectory to the connecting port 11h, thereby facilitating the airflow from the air inlet 11a to the first installation area 11f.

[0049] In related technologies, after the hot and humid airflow leaves the cylinder assembly and enters the air duct, it needs to change its flow direction. This easily leads to turbulence at the air inlet of the air duct, causing it to spread in all directions and fail to concentrate its flow towards the condenser dehumidifier, thus affecting drying efficiency. Furthermore, the airflow tends to stagnate at the air inlet, accumulating the lint it carries. This not only contaminates the air duct but also causes blockages due to the accumulated lint, hindering the airflow from the cylinder assembly into the air duct. Specifically, when the airflow flows at the air inlet of the air duct, part of it is located on the side of the air inlet closer to the connecting opening, allowing it to flow more easily towards the connecting opening. The other part is located on the side of the air inlet farther from the connecting opening. The inner edge of the air inlet and the side wall of the second installation area are spaced apart to form a stepped surface. The airflow on the side of the air inlet farther from the connecting opening is unguided and tends to stagnate on the stepped surface, causing the lint it carries to accumulate and contaminate the air duct.

[0050] The garment processing device 1 provided in this application embodiment has a guide member 12 that can guide the hot and humid airflow leaving the drum assembly 10 through the air inlet 11a, facilitating the formation of an airflow path. This allows the hot and humid airflow to flow concentratedly towards the connecting port 11h, thereby increasing drying efficiency and reducing the probability of turbulence affecting drying efficiency. Furthermore, the airflow carrying lint can be concentrated towards the connecting port 11h after being guided by the guide member 12, reducing the residence time and area of ​​the airflow at the air inlet 11a, thereby reducing the accumulation of lint at the air inlet 11a, increasing the cleanliness of the air duct 11b, and improving drying reliability.

[0051] In some embodiments, the second mounting area 11g is located behind the first mounting area 11f, and the guide member 12 has an arc-shaped guide surface that is adapted to deflect the upward airflow at the air inlet 11a forward to the connecting port 11h.

[0052] Understandably, "back side" refers to the side of the garment processing equipment 1 that is furthest from the user in the front-back direction after installation.

[0053] It is understandable that the second installation area 11g is located behind the first installation area 11f, that is, the connecting port 11h is arranged in the front-to-back direction, and the airflow from the second installation area 11g into the connecting port 11h flows roughly from back to front.

[0054] Specifically, the airflow flows from bottom to top at the air inlet 11a. The guide element 12 guides the airflow at the air inlet 11a, deflecting it forward to the connecting port 11h, and then into the first installation area 11f. That is, the airflow through the air inlet 11a flows from bottom to top, and the airflow through the connecting port 11h flows from back to front. The guide element 12 changes the direction of airflow, causing the airflow to concentrate towards the first installation area 11f, reducing the probability of turbulence. The arc-shaped guide surface also reduces airflow resistance and increases the reliability of the guide.

[0055] In some embodiments, referring to FIG3, the flow guide 12 divides the second installation area 11g into a first subspace 11d and a second subspace 11e, wherein the first subspace 11d is located on the side of the flow guide 12 facing the connection port 11h, and the first subspace 11d and the second subspace 11e are not connected to each other, so that the airflow at the air inlet 11a flows to the connection port 11h through the first subspace 11d.

[0056] In other words, the guide member 12 can divide the second installation area 11g into a first subspace 11d and a second subspace 11e by its own structure. When the hot and humid airflow flows from the outlet to the inlet 11a, the first subspace 11d and the second subspace 11e are not connected. That is, under the action of the guide member 12, the hot and humid airflow can concentrate and flow to the connecting port 11h through the first subspace 11d, while flowing less or almost not in the second subspace 11e, reducing turbulence and increasing the stability of airflow. Furthermore, it can also reduce the probability of airflow staying on the side of the guide member 12 away from the connecting port 11h, causing lint to accumulate on the guide member 12, thus increasing the cleanliness of the air duct 11b.

[0057] The specific structure of the flow guide 12 is not limited.

[0058] In some embodiments, please refer to Figures 3 and 5. The drying tunnel assembly 11 includes a bottom cover 111, an air inlet 11a is disposed on the bottom cover 111, and the flow guide 12 includes a connecting seat 121 and a flow guide shroud 122 connected to each other. The connecting seat 121 is connected to the bottom cover 111, and the flow guide shroud 122 has a communicating flow guide cavity 122a and an airflow outlet 122b. The airflow outlet 122b is located on the side of the flow guide 12 facing the communicating port 11h.

[0059] In other words, the guide 12 is connected to the bottom cover 111 through the connecting seat 121, and guides the hot and humid airflow through the guide shroud 122. The hot and humid airflow is guided by the guide shroud 122 at the air inlet 11a, flows through the guide cavity 122a, flows out from the air outlet 122b, and then flows to the connecting port 11h.

[0060] In this embodiment, the structure of the guide member 12 is simple. The connecting seat 121 is connected to the bottom cover 111, which facilitates the stable installation of the guide member 12 on the drying tunnel assembly 11. Thus, when the airflow passes through the guide member 12, the guide member 12 can stably accept the impact of the airflow. An airflow passage is formed inside the guide shroud 122, so that the airflow flows along a predetermined trajectory to the connecting port 11h. The airflow outlet 122b is located on the side of the guide member 12 facing the connecting port 11h, which enables the airflow to flow out from the guide cavity 122a and then concentrate and quickly flow to the second installation area 11g.

[0061] In some embodiments, please refer to FIG5, the connecting seat 121 is an annular structure surrounding the air inlet 11a, the air guide shroud 122 is bowl-shaped and covers the annular structure, and the air outlet 122b penetrates the side wall of the air guide shroud 122 and extends to the annular structure.

[0062] In other words, the connecting seat 121 is roughly annular, with the annular structure surrounding the air inlet 11a. This means that the connecting seat 121 is arranged around the air inlet 11a, allowing the airflow exiting from the air inlet 11a to flow primarily within the guide member 12, reducing the probability of airflow leakage at the air inlet 11a and the connecting seat 121, and increasing the reliability of the guide member 12. The airflow outlet 122b penetrates the side wall of the guide shroud 122 and extends to the annular structure. Therefore, the airflow outlet 122b has a large area, allowing sufficient airflow to exit the guide member 12 and enter the connecting port 11h per unit time, resulting in a large airflow volume and improved guide efficiency.

[0063] The bowl-shaped structure refers to the air cover 122 being an arc-shaped structure similar in shape to a bowl, which can reduce airflow resistance.

[0064] The connecting seat 121 and the flow guide 122 can be a separate structure or an integrated structure, without any limitation. That is, the flow guide 12 can be a separate structure or an integrated structure.

[0065] In some embodiments, referring to Figure 4, the central angle α corresponding to the circumferential extension length of the part where the flow guide 122 is connected to the annular structure is 150° to 210°, that is, 150°≤α≤210°, for example, 150°, 155°, 159°, 160°, 165°, 172°, 176°, 180°, 188°, 193°, 205°, 210°, etc.

[0066] In this embodiment, the central angle corresponding to the circumferential extension length of the part where the flow guide 122 is connected to the annular structure is appropriate. On the one hand, this ensures that the flow guide 122 has sufficient area to guide the airflow toward the connecting port 11h, reducing the probability of the airflow overflowing outward after passing through the flow guide 12 and increasing the flow guiding effect of the flow guide 122. On the other hand, it also ensures that the area of ​​the airflow outlet 122b is not too small, and that there is sufficient airflow per unit time, increasing the flow guiding efficiency.

[0067] In some embodiments, referring to Figures 5 and 6, the flow guide 122 includes a first sidewall 1221 and two second sidewalls 1222. The bottom end of the first sidewall 1221 extends along the inner edge of the annular structure. The two opposite ends of the first sidewall 1221 in the circumferential direction are respectively connected to the two second sidewalls 1222. In a direction away from the first sidewall 1221, the bottom ends of the two second sidewalls 1222 extend from the inner edge of the annular structure toward the outer edge of the annular structure.

[0068] That is, the guide 12 gradually expands from the first sidewall 1221 to the second sidewall 1222. Please refer to Figure 6. The dashed line R is the part of the inner edge of the annular structure that is not shown in the figure. The first sidewall 1221 is within the range defined by the dashed lines R, L1, and L2. The two second sidewalls 1222 extend in directions away from each other.

[0069] In this embodiment, the first sidewall 1221 extends along the inner edge of the annular structure, meaning there is no gap between the bottom of the first sidewall 1221 and the inner edge of the connecting seat 121. In other words, no step surface is formed between the bottom of the first sidewall 1221 and the inner edge of the annular structure. When the airflow from the outlet 10b enters the inlet 11a, it will not stay between the bottom of the first sidewall 1221 and the inner edge of the connecting seat 121 and accumulate lint, thus increasing the cleanliness of the air duct 11b. The bottom ends of the two second sidewalls 1222 extend from the inner edge of the connecting seat 121 toward the outer edge of the connecting seat 121, which allows the airflow to have sufficient outflow space when it flows out of the guide member 12, increasing the guiding efficiency.

[0070] In some embodiments, please refer to Figures 1 to 3, the clothing processing device 1 includes a connecting pipe 13, which connects an air outlet 10b and an air inlet 11a.

[0071] In other words, the cylinder assembly 10 is connected to the drying tunnel assembly 11 through the connecting pipe 13, so that the airflow flows out from the air outlet 10b and then flows into the air inlet 11a through the connecting pipe 13, and then enters the air duct 11b.

[0072] The form of the connecting pipe 13 is not limited; for example, it can be a commonly used water supply and drainage pipe.

[0073] For example, in some embodiments, the connecting pipe 13 is a corrugated pipe. A corrugated pipe is a flexible pipe that allows for a non-rigid connection between the cylinder assembly 10 and the drying tunnel assembly 11. This reduces the impact of vibrations caused by the rotation of internal components of the cylinder assembly 10 on the drying tunnel assembly 11, thereby enhancing the stability of the garment processing equipment 1. In addition, it reduces the positional accuracy requirements of the air outlet 10b and the air inlet 11a, improving the design flexibility of the positions of the air outlet 10b and the air inlet 11a.

[0074] The first end of the connecting pipe 13 extends into the air inlet 11a and has a flange 131. The flange 131 surrounds the air inlet 11a, and the annular structure presses the flange 131 against the bottom cover 111.

[0075] The flange 131 refers to a flange extending radially from the outer wall of the first end of the connecting pipe 13. It does not imply that the formation of this structure depends on the flange process in the manufacturing process. The flange 131 can be formed in any way, such as by stamping, casting or injection molding.

[0076] The flange 131 surrounds the air inlet 11a, meaning that the size of the flange 131 is larger than that of the air inlet 11a. The annular structure presses the flange 131 against the bottom cover 111, that is, the flange 131 is sandwiched between the connecting seat 121 and the bottom cover 111.

[0077] For example, the garment processing device 1 may be provided with a connector that connects the connecting seat 121, the bottom cover 111, and the connecting tube 13. During connection, the connector can pass through the connecting seat 121, the flange 131, and the bottom cover 111 in sequence and connect them. After connection, the connecting seat 121 and the bottom cover 111 press the flange 131 tightly. In this way, the flange 131 is subjected to more uniform stress deformation along the circumference, and the contact between the flange 131 and the connecting seat 121 and the bottom cover 111 is tighter, resulting in better sealing. In addition, the connector does not directly apply force to the flange 131, reducing local stress concentration on the flange 131 and improving the service life of the flange 131. The connector can be a fastener such as a screw, and there are no restrictions on its use.

[0078] Furthermore, during the assembly of the connecting pipe 13, the first end of the connecting pipe 13 can be inserted into the air inlet 11a, so that the flange 131 is hung on the bottom cover 111. At this time, even if the operator lets go, the flange 131 will not come off from the air inlet 11a, and the assembly reliability is high.

[0079] It should be noted that the material of the flange 131 is not limited. For example, the flange 131 can be made of plastic material, such as polyethylene plastic or polypropylene plastic, which can undergo adaptive deformation when pressed by the connecting seat 121 and the bottom cover 111 to fit tightly with the connecting seat 121 and the bottom cover 111.

[0080] In some embodiments, the garment processing device 1 further includes a filter device 14, at least a portion of which is disposed in the first mounting area 11f for filtering the airflow passing through the filter device 14.

[0081] It is understandable that after the dry hot airflow exchanges heat and moisture with the clothes in the garment processing chamber, it will inevitably carry lint from the clothes. After entering the air duct, the lint is easy to stick to various corners of the air duct, affecting the drying efficiency and increasing the risk of dry burning of lint, thus affecting the service life of the garment processing equipment.

[0082] In this embodiment, a filter device 14 is provided to filter impurities such as lint carried by the airflow passing through the air duct 11b, thereby reducing the probability of lint from clothing sticking to the air duct 11b, improving drying efficiency, reducing the risk of dry burning of lint, and improving the working reliability and service life of the clothing processing equipment 1.

[0083] The filter device 14 has an air inlet 14a, which is connected to the connecting port 11h.

[0084] Specifically, the hot and humid airflow flows from bottom to top into the air inlet 11a, and after being guided by the guide member 12, it changes direction and flows from front to back into the connecting port 11h, and then flows through the air inlet 14a to the filter device 14. The filter device 14 intercepts and stores impurities such as lint carried in the airflow, thereby reducing the impurity content in the airflow flowing out of the filter device 14.

[0085] It is understood that the specific structure of the condenser dehumidifier and the heating element is not limited. For example, the condenser dehumidifier can dehumidify the airflow by condensing water, and the heating element can be a resistance wire heating element.

[0086] In other embodiments, the clothing processing device 1 includes an evaporator and a condenser, wherein the condensing dehumidification component is the evaporator and the heating component is the condenser.

[0087] The evaporator and condenser are located within the first installation area 11f. The evaporator is located downstream of the filter device 14 along the airflow direction, and the condenser is located downstream of the evaporator along the airflow direction.

[0088] In other words, after the airflow passes through the filter device 14, it comes into contact with the evaporator and condenser in sequence and exchanges heat, thus leaving the air duct 11b and entering the clothing processing chamber 10a.

[0089] Specifically, the hot and humid airflow leaves the garment processing chamber 10a and enters the air duct 11b. At the air inlet 11a, it is guided by the guide component 12 to the filter device 14. The filter device 14 filters out impurities carried in the airflow. When it flows through the evaporator, it absorbs heat and lowers its temperature, becoming a low-temperature dry airflow. Then it flows through the condenser, where it absorbs heat and raises its temperature, becoming a dry hot airflow. The dry hot airflow leaves the air duct 11b and re-enters the garment processing chamber 10a. This cycle continues to achieve continuous drying of the garments.

[0090] Of course, in some embodiments, the garment processing device 1 also includes a compressor for compressing the refrigerant. The compressor has an intake port and an exhaust port. The compressor draws in refrigerant with a lower temperature and lower pressure from the intake port and compresses the refrigerant by driving a piston through the operation of a motor. The condenser is connected to the exhaust port of the compressor and is used to cool the refrigerant. The condenser heats up and then heats the airflow. The evaporator is connected to the intake port of the compressor and is used to heat the refrigerant. The evaporator absorbs heat and then condenses and dehumidifies the airflow.

[0091] Understandably, in some examples, the garment processing device 1 also includes a heater located within the air duct 11b and downstream of the evaporator in the direction of airflow. The heater is used to heat the airflow, meaning that the heater and the condenser work together to heat the airflow, thereby increasing the drying temperature and improving drying efficiency.

[0092] The filter device 14 can also reduce the chance of impurities such as lint sticking to the heater, reduce the risk of lint burning, and further improve the working reliability and service life of the garment processing equipment 1.

[0093] In some embodiments, referring to Figures 1 and 3, the filter device 14 is drawn away from the air duct 11b in the front-back direction and away from the guide member 12.

[0094] In other words, the filter device 14 and the air duct 11b can be detachably coupled, that is, the air inlet 14a and the connecting port 11h of the filter device 1 can be detachably coupled. When the filter device 14 needs to be cleaned, it can be pulled out from the back to the front, cleaned, and then installed in the air duct 11b from the front to the back. This makes it convenient for users to install and clean. In addition, the filter device 14 will not interfere with the guide component 12 during the extraction or installation process, and there is no need to remove the guide component 12 first, which makes the operation very convenient.

[0095] For example, the air inlet 14a and the connecting port 11h are sealed together in the front-to-back direction.

[0096] Specifically, after being guided by the guide member 12 at the air inlet 11a, the airflow flows through the connecting port 11h to the air inlet 14a, and then enters the filter device 14 for filtration. The filter device 14 is sealed to the connecting port 11h, which can reduce the probability of leakage of airflow during the process of flowing to the air inlet 14a, increase the stability of airflow, and reduce the probability of turbulence.

[0097] It is understood that the filter device 14 may also have an air outlet, which may be located on one side of the filter device 14 in the left-right direction.

[0098] In other words, the air inlet 14a and the air outlet of the filter device 14 are arranged in different directions, which facilitates the connection of the filter device 14 with other structures in different directions. For example, the evaporator and the condenser can be arranged side by side with the filter device 14 in the left and right directions, and the airflow from the air outlet can flow to the evaporator and the condenser in roughly the left and right directions.

[0099] The specific structure of the drying tunnel assembly 11 is not limited.

[0100] In some embodiments, the drying duct assembly 11 includes a bottom cover 111 and a cover plate assembly, with an air inlet 11a disposed on the bottom cover 111, and the cover plate assembly docking with the bottom cover 111 along the height direction of the garment processing equipment 1 and defining an air outlet duct 11b.

[0101] The cover assembly is used to cover the bottom cover 111 and close the top opening of the bottom cover 111, thereby forming an air duct 11b between the cover assembly and the bottom cover 111 to allow airflow and improve drying reliability.

[0102] The specific construction of the cover plate assembly is not limited.

[0103] In some embodiments, referring to Figures 1 to 3, the garment processing device 1 further includes an evaporator and a condenser, which are disposed in the first mounting area 11f. The cover assembly includes a first cover 112 and a second cover 113. The first cover 112 covers the top side of the first mounting area 11f, and the second cover 113 covers the top side of the second mounting area 11g. The first cover 112 and the second cover 113 are detachably connected.

[0104] In other words, when it is necessary to remove the guide 12 from the bottom cover 111 for cleaning or replacement, or to connect the drying tunnel assembly 11 with the connecting pipe 13 to connect the air inlet 11a with the air outlet 10b, it is only necessary to disconnect the second cover 113 from the first cover 112. There is no need to remove the first cover 112 and the second cover 113 at the same time. This makes the operation simple and convenient and reduces the disassembly and assembly process.

[0105] The detachable connection method of the first cover plate 112 and the second cover plate 113 is not limited, and can be threaded connection, snap-fit, etc., without restriction.

[0106] In some embodiments, please refer to Figures 2 to 5. The top wall of the flow guide 122 is provided with an operation port 122c, which extends to the airflow outlet 122b. The second cover plate 113 has a positioning post 1131 protruding toward the flow guide 12, which extends into the operation port 122c.

[0107] In this embodiment, the positioning post 1131 extends into the operating port 122c, facilitating the installation and positioning of the second cover plate 113 and the guide member 12. It also enables positioning of the guide member 12 when the second cover plate 113 aligns with the second installation area 11g, increasing installation reliability. The operating port 122c extends to the airflow outlet 122b, thus providing sufficient space for operators to connect the connecting seat 121, the bottom cover 111, and the connecting pipe 13.

[0108] In some embodiments, the cover assembly includes a seal disposed on the second cover 113 for sealing the operating port 122c when the second cover 113 is placed over the top side of the second mounting area 11g.

[0109] In this embodiment, the sealing element makes it less prone to air leakage at the joint between the second cover plate 113 and the guide member 12, reducing the probability of airflow flowing out of the second cover plate 113 through the operation port 122c, and increasing the stability of airflow within the air duct 11b.
