Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and in particular relates to a clothing processing device and a condenser assembly thereof. Background Art

[0002] Wall-mounted washing machines, as small-capacity laundry appliances, are becoming more and more popular among consumers.

[0003] Existing wall-mounted drum washing machines generally only have washing and dehydration functions, but cannot dry clothes. Users need to hang clothes to dry after washing. In some southern and coastal cities, it is often rainy and sunny, which makes it difficult to dry washed clothes. However, purchasing both a washing machine and a dryer requires a certain amount of space and financial resources.

[0004] Chinese patent application number CN201811015088.9 discloses a wall-mounted clothing processing device, including a barrel assembly, a drying tunnel assembly, a condenser assembly and an air duct. The condenser assembly includes a condenser shell, one end of the air duct is connected to the condenser shell, and the other end of the air duct is connected to the external space of the clothing processing device. The condenser shell has a water inlet. Along the height direction of the condenser shell, the water inlet is located between the drain outlet and the exhaust outlet, and the air outlet pipe and the water inlet are located on the two opposite side walls of the condenser shell.

[0005] Chinese patent application number CN201921714835.8 discloses a condenser for clothing care, comprising a condensing chamber, a first inlet, and a first outlet. The first inlet is disposed at one end of the condenser to receive hot and humid air, which condenses in the condensing chamber to form dry air. The first outlet is disposed at the other end of the condensing chamber to discharge the dry air. A damper is disposed on the sidewall of the condensing chamber to discharge some of the hot and humid air. The condenser also includes a second inlet disposed at the top of the condensing chamber. Condensation water enters through the second inlet and comes into contact with the hot and humid air in the condensing chamber, causing the hot and humid air to condense. Dry air is discharged from the air outlet, thereby improving condensation efficiency through water cooling.

[0006] In the above patent documents, in the wall-mounted clothes processing equipment, water used as a refrigerant enters the condensation space through a water inlet pipe, which makes the flow direction of the water relatively single after entering the condensation space, and the condensation efficiency is low.

[0007] In view of this, the present invention is proposed. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a condenser assembly for clothing processing equipment. A refrigerant conduit is arranged on the outer wall of the condensation chamber and the refrigerant conduit is arranged at an angle. Therefore, the refrigerant conduit and the inner wall surface of the condenser cover form an intersection line of an elliptical structure, so that the refrigerant completes the first flow distribution of the refrigerant at the same time as it enters the condensation chamber, thereby improving the condensation efficiency of the refrigerant on humid hot air.

[0009] Another object of the present invention is to provide a clothes treating device comprising the above-mentioned condenser assembly.

[0010] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0011] A condenser assembly of a clothes processing device includes a condensing chamber for condensing hot and humid air into dry and cold air;

[0012] A refrigerant conduit for inputting refrigerant into the condensing chamber is provided on the outer wall of the condensing chamber. The intersection line between the inner wall surface of the condensing chamber and the refrigerant conduit is elliptical, and the area defined by the intersection line constitutes the refrigerant inlet of the condensing chamber.

[0013] Furthermore, it also includes a condenser body and a condenser cover, wherein the condenser body and the condenser cover are buckled and connected to form the condensation chamber;

[0014] The refrigerant conduit is arranged on the outer wall of the condenser cover, and the axis of the refrigerant conduit extends in the transverse direction.

[0015] Furthermore, the ratio of the major axis to the minor axis of the intersection line is in the range of 4:1 to 6:1.

[0016] Furthermore, a guide plate protruding from the inner wall surface is provided on the inner wall surface of the condenser cover, and the guide plate has an intersection with the extension line of the long axis of the intersection line.

[0017] Furthermore, the guide plate is an arc-shaped structure, and the convex surface of the guide plate faces the side of the refrigerant inlet.

[0018] Furthermore, a refrigerant redistributor is provided on the inner wall surface of the condenser cover, and a tangent line of the end of the guide plate from which the refrigerant is separated intersects with a range covered by an inlet of the refrigerant redistributor;

[0019] Preferably, the intersection point between the guide plate and the extension line of the major axis of the intersection line is located upstream of the inflection point of the arc-shaped guide plate.

[0020] Furthermore, the refrigerant redistributor includes an arc-shaped plate, the arc-shaped plate protrudes from the inner wall surface of the condenser cover, and the concave surface of the arc-shaped plate faces the side of the refrigerant inlet;

[0021] The recess of the arc-shaped plate forms the inlet of the refrigerant redistributor.

[0022] Furthermore, the arc-shaped plate is provided with at least two through-gaps extending radially along the circumferential direction, and the through-gaps are higher than the lowest position of the arc-shaped plate.

[0023] Furthermore, reinforcing ribs are provided on the outer wall of the condenser cover.

[0024] A clothes treating device comprises the condenser assembly as described above.

[0025] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0026] The present invention arranges a refrigerant conduit on the outer wall of the condensation chamber and arranges the refrigerant conduit at an angle. Therefore, the refrigerant conduit and the inner wall surface of the condensation chamber form an intersection line of an elliptical structure, so that the refrigerant does not enter the condensation chamber in a single flow direction, but forms a dispersed flow direction on the elliptical surface. Therefore, the refrigerant completes the first flow distribution at the same time as entering, thereby improving the heat and mass exchange rate between the refrigerant and the humid hot air, and then improving the condensation efficiency of the refrigerant on the humid hot air, thereby improving the drying efficiency of the clothing processing equipment.

[0047] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0049] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0050] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0051] like Figures 1 to 15 As shown, the present invention provides a clothing processing device and a condenser assembly thereof. The condenser assembly 30 includes a condensing chamber for condensing hot and humid air into dry, cold air. A refrigerant conduit 33 for supplying refrigerant to the condensing chamber is provided on the outer wall of the condensing chamber. The intersection line 34 between the inner wall of the condensing chamber and the refrigerant conduit 33 is elliptical, and the area defined by the intersection line 34 constitutes a refrigerant inlet 35 for the condensing chamber.

[0052] Further, such as Figure 1 and Figure 2As shown, the laundry processing apparatus further includes a laundry processing drum 10 and a heater assembly 20. The condensing chamber further includes an air inlet for receiving moist, hot air and an air outlet for exhausting the air. The air inlet communicates with the laundry processing drum 10 of the laundry processing apparatus, and the air outlet communicates with the inlet of a fan 25 of the heater assembly 20. The heater assembly 20 includes an air duct, within which are disposed the fan 25 and a heater for heating the air.

[0053] When the laundry processing apparatus is drying clothes, the hot and humid air in the laundry processing drum 10 enters the condensation chamber of the condenser assembly 30 through the air inlet, and the refrigerant enters the condensation chamber through the refrigerant inlet 35. After the hot and humid air condenses in the refrigerant, it becomes dry cold air, which is discharged through the air outlet. After being pressurized and guided by the fan 25 in the air duct and heated by the heater, it becomes dry hot air for drying, which is further circulated into the laundry processing drum 10 to dry the clothes.

[0054] It can be seen that in the condensation chamber, the heat and mass transfer process between the refrigerant and the hot and humid air is the decisive factor in the drying efficiency.

[0055] The present invention sets a refrigerant conduit 33 on the outer wall of the condensing chamber and sets the refrigerant conduit 33 at an angle. Therefore, the refrigerant conduit 33 and the inner wall of the condensing chamber form an elliptical intersection line 34. Figure 3 As shown, the refrigerant does not enter the condensation chamber in a single flow direction, but forms a dispersed flow direction on the elliptical surface. Therefore, the refrigerant completes the first flow distribution at the same time as entering, thereby increasing the heat and mass exchange rate between the refrigerant and the hot and humid air, thereby increasing the condensation efficiency of the refrigerant on the hot and humid air, thereby improving the drying efficiency of the clothing processing equipment.

[0056] In further solutions, such as Figures 4 to 7 As shown, the condenser assembly 30 includes a condenser body 31 and a condenser cover 32. The condenser body 31 and the condenser cover 32 are fastened together to form a condensing chamber. A refrigerant conduit 33 is disposed on the outer wall of the condenser cover 32. The intersection line 34 between the inner wall of the condenser cover 32 and the refrigerant conduit 33 is an ellipse. The area defined by the intersection line 34 constitutes a refrigerant inlet 35 for the condensing chamber. The axis of the refrigerant conduit 33 extends horizontally.

[0057] The refrigerant of the present invention is preferably tap water. Air has a low solubility in tap water, and using tap water as a refrigerant offers the advantages of a reliable source and simple recycling. Furthermore, the water inlet assembly of the wall-mounted laundry treatment device is generally located below the laundry treatment tub 10. Furthermore, the air outlet of the laundry treatment tub 10 is generally located at a lower position, while the refrigerant inlet 35 is located at a higher position. Thus, under the action of lift, the hot and humid air moves upward from the bottom, while under the action of gravity, the refrigerant moves downward from the top. During the cross-convection process, the refrigerant condenses the water vapor in the hot and humid air into condensed water, which is then discharged from the air outlet of the condensation chamber.

[0058] The present invention sets the refrigerant conduit 33 on the outer wall of the condenser cover 32, and extends the axis of the refrigerant conduit 33 in the horizontal direction. On the one hand, it is convenient for the refrigerant conduit 33 to be connected with the water inlet component of the clothing processing equipment. On the other hand, when the refrigerant enters the condensation chamber through the refrigerant conduit 33, the refrigerant can be fully dispersed in the horizontal direction, thereby increasing the area of ​​the refrigerant moving from top to bottom.

[0059] In a preferred embodiment of the present invention, the ratio of the major axis to the minor axis of the intersection line 34 is in the range of 4:1 to 6:1.

[0060] In detail, the shape of the intersection line 34 is an ellipse, and the ratio of the major axis to the minor axis of the ellipse is between 4:1 and 6:1, so that the ellipse as a whole is slender, further allowing the refrigerant to be fully dispersed in the lateral direction, increasing the area of ​​the refrigerant moving from top to bottom.

[0061] In addition, the ratio between the major axis of the ellipse and the transverse dimension of the condenser cover 32 should be between 2:5 and 3:5.

[0062] In some embodiments of the present invention, in order to further guide the flow direction of the refrigerant in the condensing chamber, a guide plate 36 protruding from the inner wall surface is provided on the inner wall surface of the condenser cover 32, and the guide plate 36 has an intersection with the extension line of the long axis of the intersection line 34.

[0063] Detailed, such as Figure 6 and Figure 7 As shown, after the refrigerant enters the condensing chamber through the elliptical refrigerant inlet 35, although the elliptical structure performs a first refrigerant distribution, if the refrigerant enters at a high speed, a large amount of refrigerant will move along the long axis of the elliptical structure, which is not conducive to the dispersion of the refrigerant. Therefore, the present invention provides a guide plate 36 downstream of the refrigerant inlet 35. When the refrigerant flows along the long axis of the elliptical structure, it will impact the guide plate 36. Under the blocking effect of the guide plate 36, the refrigerant flow direction is changed, and the second refrigerant distribution is achieved.

[0064] The guide plate 36 may be a flat plate structure. The guide plate 36 of the flat plate structure has a reflection effect on the refrigerant, thereby changing the flow direction of the refrigerant.

[0065] However, in a preferred embodiment of the present invention, the guide plate 36 is an arc-shaped structure, and the convex surface of the guide plate 36 faces one side of the refrigerant inlet 35. The convex structure of the guide plate 36 has a diverging effect on the refrigerant, further enhancing the contact area between the refrigerant and the humid hot air.

[0066] In a further solution, a refrigerant redistributor is provided on the inner wall surface of the condenser cover 32 , and a tangent line of the end of the guide plate 36 from which the refrigerant is separated intersects with a range covered by an inlet of the refrigerant redistributor.

[0067] In a preferred solution, the intersection point between the guide plate 36 and the extension line of the long axis of the intersection line 34 is located upstream of the inflection point of the arc-shaped guide plate 36 .

[0068] Specifically, to further enhance the refrigerant's condensation effect on hot and humid air, the present invention incorporates a refrigerant redistributor on the inner wall of the condenser cover 32, which performs a third refrigerant redistribution. Guide plates 36 disperse the refrigerant in all directions of the condensing chamber, but some refrigerant still flows along the inner wall of the condenser cover 32 under the influence of guide plates 36. Therefore, to ensure that this portion of refrigerant fully covers the inner wall of the condenser cover 32, a refrigerant redistributor is provided downstream of guide plates 36.

[0069] It should be noted that the tangent line of the end of the guide plate 36 where the refrigerant is separated should fall into the inlet of the refrigerant redistributor so that this part of the refrigerant can be redistributed.

[0070] In some embodiments of the present invention, Figure 8 As shown, the refrigerant redistributor includes an arc-shaped plate, which protrudes from the inner wall surface of the condenser cover 32, and the concave surface of the arc-shaped plate faces one side of the refrigerant inlet 35; the notch of the arc-shaped plate constitutes the inlet of the refrigerant redistributor, and the two sides of the arc-shaped plate constitute the outlet of the refrigerant redistributor.

[0071] In detail, the concave surface of the arc-shaped plate faces one side of the refrigerant inlet 35, so that the refrigerant flowing along the guide plate 36 falls on the concave surface of the arc-shaped plate. Under the blocking effect of the arc-shaped plate, the flow direction of the refrigerant is changed to achieve the third refrigerant distribution.

[0072] In some other embodiments of the present invention, the arc-shaped plate is provided with at least two through-gaps 371 extending radially along the circumference, and the through-gaps 371 are higher than the lowest position of the arc-shaped plate.

[0073] In detail, at least two through gaps 371 separate the arc-shaped plate into at least a first arc-shaped plate 37, a second arc-shaped plate 38 and a third arc-shaped plate 39. The first arc-shaped plate 37, the second arc-shaped plate 38 and the third arc-shaped plate 39 are in an embracing structure. The refrigerant flowing down the guide plate 36 falls on the concave surfaces of the first arc-shaped plate 37, the second arc-shaped plate 38 and the third arc-shaped plate 39. Under the dispersion effect of the first arc-shaped plate 37, the second arc-shaped plate 38 and the third arc-shaped plate 39, the flow direction of the refrigerant is changed.

[0074] In some embodiments of the present invention, Figure 5 As shown, in order to prevent the deformation of the condenser cover 32 caused by a large temperature gradient in the condensation chamber, a reinforcing rib 321 is provided on the outer wall of the condenser cover 32 .

[0075] In detail, the reinforcing ribs 321 include transverse reinforcing ribs 321 , longitudinal reinforcing ribs 321 and arc-shaped reinforcing ribs 321 , and the reinforcing ribs 321 are cross-arranged on the outer wall surface of the condenser cover 32 .

[0076] In some embodiments of the present invention, the laundry treatment drum 10 includes an outer drum and an inner drum, and the condenser body 31 is integrally formed with the outer drum. Figure 3 shown.

[0077] The clothes processing device of the present invention is preferably a drum washer-dryer, more preferably a wall-mounted washer-dryer.

[0078] In some embodiments of the present invention, the air duct includes a fan 25 housing for installing the fan 25, a drying duct body 21 for installing the heater, and an air guide channel 22 provided on the front side of the outer cylinder and communicating with the inner cylinder.

[0079] In detail, the fan 25 shell includes a fan lower shell 261 and a fan upper shell 26 that are snap-fitted together, and the drying tunnel body 21 includes a drying tunnel lower shell 212 and a drying tunnel upper shell 211 that are snap-fitted together, wherein the fan lower shell 261 and the drying tunnel lower shell 212 are integrally formed.

[0080] Specifically, such as Figure 1 As shown, the air outlet of the fan 25 housing is connected to the air inlet of the drying tunnel body 21, and is used to introduce air into the drying tunnel body 21 to be heated by the heating device 24. The air discharged from the condensing assembly is heated in the drying tunnel body 21 and then introduced into the clothes processing drum 10 of the wall-mounted clothes processing device through the air guide channel 22 to remove moisture from the clothes, thereby achieving the purpose of drying the clothes.

[0081] It can be seen that the sealing performance between the housing of the fan 25 and the drying tunnel body 21 directly affects the drying efficiency of the clothes processing equipment.

[0082] like Figure 14As shown, the present invention provides a seal 27 between the fan upper shell 26 and the drying tunnel upper shell 211, so that a sealed connection is formed between the fan upper shell 26 and the drying tunnel upper shell 211, ensuring the sealing between the fan 25 shell and the drying tunnel body 21, preventing air leakage, and thus improving the drying efficiency.

[0083] In a further embodiment, the seal 27 includes a body and a boss 271 protruding from the surface of the body; the drying tunnel upper shell 211 and / or the fan upper shell 26 are provided with a mounting hole 262; the body is clamped between the drying tunnel upper shell 211 and the fan upper shell 26, and the boss 271 is embedded in the mounting hole 262.

[0084] In detail, the shapes and sizes of the drying tunnel upper shell 211 and the fan upper shell 26 at least at the connection point should match each other so that the drying tunnel upper shell 211 and the fan upper shell 26 can be assembled.

[0085] Therefore, it can be understood that the shape and size of the main body of the sealing member 27 also match the shape and size of the connection between the drying tunnel upper shell 211 and the fan upper shell 26.

[0086] like Figure 15 As shown, for example, the main body of the sealing member 27 is a sheet-like sealing strip. When assembling the drying tunnel upper shell 211 and the fan upper shell 26, the drying tunnel upper shell 211 and the lower shell are first fixedly connected, and then the sealing member 27 is placed at the connection between the drying tunnel upper shell 211 and the fan upper shell 26. Finally, the fan upper shell 26 and the lower shell are fixedly connected. In this way, the sealing member 27 is compressed between the drying tunnel upper shell 211 and the fan upper shell 26. Furthermore, the sealing member 27 can be made of a flexible material such as rubber.

[0087] Moreover, a plurality of bosses 271 protruding from the surface are provided on the surface of the main body of the seal 27, and mounting holes 262 are also provided on the drying tunnel upper shell 211 and / or the fan upper shell 26. When the seal 27 is placed at the connection between the drying tunnel upper shell 211 and the fan upper shell 26, the bosses 271 are correspondingly inserted into the mounting holes 262. When the fan upper shell 26 is fixedly connected to the lower shell, the mounting holes 262 are also aligned with the bosses 271. As a result, the seal 27 is pressed between the drying tunnel upper shell 211 and the fan upper shell 26. At the same time, the bosses 271 are fixed in the mounting holes 262, which can prevent the seal 27 from slipping and further enhance the sealing performance.

[0088] Furthermore, the mounting hole 262 can be a mounting column with a through hole protruding outward from the outer wall of the fan upper shell 26 , and the through hole constitutes the mounting hole 262 .

[0089] It should be noted that the assembly order of the above components can be adjusted according to actual conditions.

[0090] The lower shell, the drying tunnel upper shell 211 and the fan upper shell 26 may be partially or entirely made of sheet metal parts.

[0091] In some embodiments of the present invention, the drying tunnel upper shell 211 and / or the fan upper shell 26 are provided with grooves for mounting the body, which can further limit the body of the seal 27 and prevent the seal 27 from slipping.

[0092] In some embodiments of the present invention, Figure 8 and Figure 11 As shown, the drying tunnel body 21 of the present invention is further provided with an installation opening 219 opposite the air outlet. This installation opening 219 can be formed by a combination of openings provided on the drying tunnel upper shell 211 and the drying tunnel lower shell 212. Furthermore, the heating device 24 includes a heating tube 241 and a terminal 242 provided at the end of the heating tube 241. The heating tube 241 is installed within the airflow channel of the drying tunnel body 21. The extension direction of the heating tube 241 is consistent with the airflow direction within the drying tunnel body 21, and the terminal 242 is installed within the installation opening 219. Preferably, the heating tube 241 includes several extension sections that are consistent with the airflow direction within the drying tunnel body 21. Except for the extension section connected to the terminal 242, each extension section has a bend at each end connecting to the adjacent extension section.

[0093] In the above scheme, the mounting opening 219 for mounting the terminal block 242 is arranged opposite to the air outlet, and the extension direction of the heating tube 241 is made consistent with the direction of the airflow in the drying tunnel body 21. This can reduce the number of elbows in the spiral structure of the heating tube 241, thereby reducing the impact of the elbows on the airflow, reducing the flow loss of the airflow in the drying tunnel body 21, and achieving the purpose of improving the drying efficiency.

[0094] In addition, since the overall size of the wall-mounted clothes processing device is relatively small, the above-mentioned installation structure of the present invention arranges the heating pipe 241 in the front-to-back direction, maximizes the channel space of the drying channel body 21, increases the area of ​​the heating pipe 241, and improves the drying rate.

[0095] In addition, a fixing structure for fixing the end of the heating tube 241 is provided near the air outlet of the drying tunnel body 21. The heating tube 241 is fixed by fastening the fixing structure to the drying tunnel body 21, thereby providing stability to the heating tube 241.

[0096] Furthermore, the fixing structure may be a metal sheet, specifically a copper sheet, a stainless steel sheet, or the like.

[0097] Furthermore, a fan 25 is disposed within the fan housing 25, so that the fan housing 25 serves as a conduit for conveying air into the drying tunnel body 21. To further increase the size of the heating tube 241, the present invention provides for an angle between the air outlet direction within the fan housing 25 and the air inlet direction within the drying tunnel body 21. The air outlet of the drying tunnel body 21, where the heating tube 241 is disposed, can be located at the front of the laundry processing drum 10, while the mounting opening 219 for the wiring terminal 242 can be located at the rear of the laundry processing drum 10. Consequently, the drying tunnel body 21 can be arranged from front to rear above the laundry processing drum 10, significantly increasing the channel space within the drying tunnel body 21. This allows the extension of the heating tube 241 to be as long as possible, minimizing the number of bends.

[0098] In the above solution, the drying tunnel lower shell 212 and the lower shell of the fan 25 are integrally formed into a lower shell, which can reduce the assembly process. However, the drying tunnel upper shell 211 and the fan upper shell 26 are not configured to be integrally formed. In this way, when the heating tube 241 or the fan 25 fails, the drying tunnel upper shell 211 or the fan upper shell 26 can be opened separately for repair or replacement.

[0099] In some embodiments of the present invention, Figure 8 and Figure 9 As shown, the outer wall of the drying tunnel lower shell 212 is flat at the air outlet, while the upper shell 211 is curved at the air outlet. The air guide channel 22 has an outwardly folded edge at the air inlet end. The outer wall of the drying tunnel lower shell 212 is sealed to a portion of the folded edge 221 of the air guide channel 22, while the end of the drying tunnel upper shell 211 is sealed to the end face of the remaining folded edge 222 of the air guide channel 22.

[0100] Detailed, such as Figure 9 and Figure 11 As shown, using the example of a drying tunnel body 21 positioned above the laundry tub 10 of a wall-mounted laundry treatment appliance, the curved surface structure of the drying tunnel upper shell 211 is formed by a flat surface bent downward. The outer wall of the drying tunnel lower shell 212 is flat at the air outlet. In other words, the sidewalls of the drying tunnel lower shell 212 do not curve downward. In other words, the air outlet of the drying tunnel body 21 does not have an elbow structure.

[0101] The folded edge at one end of the air inlet of the air guide channel 22 is formed by folding the end of the air inlet outward. Part of the folded edge 221 is used to connect with the lower shell 212 of the drying tunnel, and the other part of the folded edge 221 is used to connect with the end of the upper shell 211 of the drying tunnel.

[0102] Specifically, the air guide channel 22 includes a first side wall, a second side wall, a third side wall, and a fourth side wall connected end to end. The width of the first and third side walls is smaller than the width of the second and fourth side walls. When the air guide channel 22 is connected to the laundry treatment drum 10, the second side wall is close to the laundry treatment drum 10, while the fourth side wall is away from the laundry treatment drum 10.

[0103] The first side wall, the second side wall, the third side wall, and the fourth side wall are all folded outward to form folded edges. Therefore, the folded edge corresponding to the second side wall is the partial folded edge 221, which is connected to the drying tunnel lower shell 212. The folded edges corresponding to the first side wall, the third side wall, and the fourth side wall are the remaining folded edges 222, which are connected to the drying tunnel upper shell 211.

[0104] When the drying tunnel body 21 is assembled with the air guide channel 22, the lower shell portion 212 of the drying tunnel is first sealed and connected with part of the folded edge 221 of the air guide channel 22. Then, the upper shell 211 of the drying tunnel is sealed and connected with the remaining folded edge 222 of the air guide channel 22. Finally, the upper shell 211 of the drying tunnel is buckled and connected with the lower shell portion 212 of the drying tunnel.

[0105] In the above solution, by configuring the drying tunnel body 21 as a separate structure consisting of an upper tunnel shell 211 and a lower tunnel shell 212, and connecting each of these to the air inlet of the air guide duct 22, a structure with a partially surface-sealed connection and a partially end-face-sealed connection is formed. This simplifies the connection between the drying tunnel body 21 and the drying duct, facilitating installation. Furthermore, the air outlet of the drying tunnel body 21 does not need to be designed as a nearly 90° elbow, reducing the manufacturing difficulty of the drying tunnel body 21 and thereby improving the product qualification rate of the drying tunnel body 21. This reduces the cost of the laundry processing equipment and overall enhances the market competitiveness of wall-mounted laundry processing equipment.

[0106] In other words, the structure of the drying tunnel body 21 of the present invention and the connection method between it and the air guide channel 22 are essentially that the outer wall surface of the drying tunnel lower shell 212 and the partial folded edge 221 of the air guide channel 22 form a surface sealing connection, and the drying tunnel upper shell 211 is buckled and connected with the drying tunnel lower shell 212 and the remaining folded edge 222 of the air guide channel 22.

[0107] In addition, the above-mentioned connection structure can also improve the sealing performance between the drying tunnel body 21 and the air guide channel 22.

[0108] In some embodiments of the present invention, Figure 9 、 Figure 11 and Figure 13As shown, the surface of the partial hem 221 formed by the folding of the second side wall lies below the plane of the surface of the remaining hem 222 formed by the folding of the remaining side walls, creating a mounting space for the air outlet portion of the drying tunnel lower shell 212. The drying tunnel lower shell 212 includes a bottom wall and side walls. After the bottom wall of the drying tunnel lower shell 212 is connected to the hem of the second side wall, the upper edge of the side wall at the air outlet of the drying tunnel lower shell 212 is flush with the surface of the hem formed by the folding of the first, third, and fourth side walls. In other words, the mating surface of the drying tunnel lower shell 212 and the drying tunnel upper shell 211 should remain flush with the surface of the remaining hem 222.

[0109] The above solution can increase the space at the junction of the drying tunnel body 21 and the air guide channel 22, thereby preventing the heated air from forming vortices there, which would affect the air intake efficiency.

[0110] In some specific embodiments of the present invention, the sealing connection between the outer wall surface of the drying tunnel lower shell 212 and the partial folded edge 221 of the air guide channel 22 includes the following three solutions.

[0111] The first option, such as Figure 9 As shown, a sealing gasket installation groove 223 is provided on the surface of the partial folded edge 221 , a sealing gasket 23 is provided in the sealing gasket installation groove 223 , and the outer wall surface of the drying tunnel lower shell 212 and the sealing gasket installation groove 223 jointly squeeze the sealing gasket 23 .

[0112] Preferably, a recessed sealing gasket installation groove 223 is provided on the surface of the partial folded edge 221, so that the sealing gasket 23 is embedded in the sealing gasket installation groove 223. When the drying tunnel lower shell part 212 and the air guide channel 22 are assembled, the sealing gasket 23 can be installed in place, and then the drying tunnel lower shell part 212 and the partial folded edge 221 are fixedly connected to squeeze the sealing gasket 23. At the same time, the buckling surface of the drying tunnel lower shell part 212 is flush with the surface of the remaining folded edge 222, thereby ensuring the integrity of the installation surface of the drying tunnel lower shell part 212 and the remaining folded edge 222, and further improving the sealing performance.

[0113] In the second solution, a lower sealing gasket installation groove 223 is provided on the surface of the partial folded edge 221, and an upper sealing gasket installation groove 223 is provided on the outer wall surface of the lower shell portion 212 of the drying tunnel. The lower sealing gasket installation groove 223 and the upper sealing gasket installation groove 223 together constitute a sealing gasket installation groove 223, and a sealing gasket 23 is provided in the sealing gasket installation groove 223.

[0114] This solution differs from the first solution in that a sealing gasket mounting groove 223 for mounting the sealing gasket 23 is provided on both the surface of the partial folded edge 221 and the outer wall surface of the drying tunnel lower shell 212. When assembling the drying tunnel lower shell 212 and the air guide duct 22, the sealing gasket 23 can be installed in any of the sealing gasket mounting grooves 223. The drying tunnel lower shell 212 is then fixedly connected to the partial folded edge 221, squeezing the sealing gasket 23 while simultaneously aligning the engagement surface of the drying tunnel lower shell 212 with the surface of the remaining folded edge 222. This ensures the integrity of the mounting surface between the drying tunnel lower shell 212 and the remaining folded edge 222, further improving sealing performance.

[0115] In a third solution, a sealing gasket installation groove 223 is provided on the outer wall surface of the drying tunnel lower shell 212 , a sealing gasket 23 is provided in the sealing gasket installation groove 223 , and the sealing gasket installation groove 223 and the surface of the partial folded edge 221 jointly squeeze the sealing gasket 23 .

[0116] This solution differs from the first solution in that a sealing gasket mounting groove 223 for mounting a sealing gasket 23 is provided on the outer wall surface of the drying tunnel lower shell portion 212. When assembling the drying tunnel lower shell portion 212 and the air guide duct 22, the sealing gasket 23 can be installed in the sealing gasket mounting groove 223. The drying tunnel lower shell portion 212 is then fixedly connected to the portion of the folded edge 221, and the sealing gasket 23 is squeezed. At the same time, the fastening surface of the drying tunnel lower shell portion 212 is flush with the surface of the remaining folded edge 222, thereby ensuring the integrity of the mounting surface of the drying tunnel lower shell portion 212 and the remaining folded edge 222, further improving the sealing performance.

[0117] In further solutions, such as Figure 10 As shown, the drying tunnel lower shell 212 is provided with a first fastening structure 213 at the air outlet, and the partial folded edge 221 is provided with a second fastening structure 224 , and the first fastening structure 213 and the second fastening structure 224 are connected.

[0118] In detail, in order to further improve the sealing performance between the drying tunnel body 21 and the air guide channel 22, after the sealing gasket 23 is extruded, the drying tunnel lower shell 212 and the partial folded edge 221 need to be connected with fasteners to make them relatively fixed, and the integrity of the installation surface of the drying tunnel lower shell 212 and the remaining folded edge 222 can be ensured.

[0119] In a preferred embodiment, the first fastening structure 213 is a protruding lug provided on the sidewall of the drying tunnel lower shell 212, with screw holes provided in the lug. Similarly, the second fastening structure 224 is a fixing plate extending further from the folded edge of the air guide channel 22, also with screw holes provided in the fixing plate. After the drying tunnel lower shell 212 and the partial folded edge 221 of the air guide channel 22 are assembled, the lug and fixing plate are tightened with screws.

[0120] In some embodiments of the present invention, Figures 10 to 13 As shown, the drying tunnel upper shell 211 is provided with a first positioning structure 214 at the air outlet, and the remaining folded edge 222 of the air guide channel 22 is provided with a second positioning structure 225 , and the first positioning structure 214 is connected to the second positioning structure 225 .

[0121] In detail, generally, the shape of the drying tunnel body 21 is irregular, so when assembling the drying tunnel lower shell 212 and the air guide channel 22, misalignment may occur. The present invention provides positioning structures on both the drying tunnel lower shell 212 and the air guide channel 22. During assembly, the positioning structures are first used to determine the approximate positional relationship between the drying tunnel lower shell 212 and the air guide channel 22 before proceeding to the next assembly process. This ensures that the drying tunnel lower shell 212 and the air guide channel 22 are assembled without misalignment, improves assembly accuracy, and further improves sealing performance, thereby preventing hot air from leaking at the connection between the drying tunnel body 21 and the air guide channel 22, thereby ensuring the heat utilization rate of the hot air and improving the drying energy efficiency of the wall-mounted clothes processing device.

[0122] There are three implementation schemes for the above-mentioned buckling connection of the drying tunnel upper shell 211, the fan upper shell 26, the lower shell and the remaining folded edges 222 of the air guide channel 22.

[0123] In the first solution, an upper sealing groove is provided on the contour line of the upper fastening surface of the upper shell 211 of the drying tunnel; a first lower sealing groove 216 is provided on the contour line of the upper fastening surface of the lower shell, and a second lower sealing groove 226 is provided on the contour line of the remaining folded edge 222. The second lower sealing groove 226 and the first lower sealing groove 216 together constitute a lower sealing groove adapted to the upper sealing groove; a sealing ring is provided between the upper sealing groove and the lower sealing groove.

[0124] In the preferred embodiment, Figure 11 As shown, ribs are provided on the mating surfaces of the drying tunnel upper shell 211 and the fan upper shell 26 to form an upper sealing groove. Ribs are provided on the mating surface of the lower shell to form a first lower sealing groove 216. Ribs are provided on the surface of the remaining folded edge 222 to form a second lower sealing groove 226. The first lower sealing groove 216 and the second lower sealing groove 226 work together to form the complete lower sealing groove. When assembling the drying tunnel upper shell 211, the fan upper shell 26, the lower shell, and the air guide duct 22, the sealing ring can be first installed in either the upper or lower sealing groove. The drying tunnel upper shell 211, the fan upper shell 26, the lower shell, and the air guide duct 22 can then be fastened together to squeeze the seal body and achieve a sealing effect.

[0125] In the second solution, an upper sealing groove is provided along the contour line of the fastening surfaces of the drying tunnel upper shell 211 and the fan upper shell 26; the fastening surface of the lower shell and the surface of the remaining folded edge 222 are planar structures; a sealing ring is provided in the upper sealing groove, and the upper sealing groove, the fastening surface of the lower shell and the surface of the remaining folded edge 222 jointly press the sealing ring.

[0126] The difference between this solution and the first solution is that only upper sealing grooves are provided on the fastening surfaces of the drying tunnel upper shell 211 and the fan upper shell 26, and the fastening surface of the lower shell and the surface of the remaining folded edge 222 are used to jointly extrude the sealing body to achieve a sealing effect.

[0127] In the third solution, a lower sealing groove is provided on the surface of the buckling surface of the lower shell and the surface of the remaining folded edge 222 along the contour line; the buckling surface of the drying tunnel upper shell 211 and the fan upper shell 26 is a planar structure; a sealing ring is provided in the lower sealing groove, and the lower sealing groove and the buckling surfaces of the drying tunnel upper shell 211 and the fan upper shell 26 jointly press the sealing ring.

[0128] The difference between this solution and the first solution is that the lower sealing groove is only provided on the buckling surface of the lower shell and the surface of the remaining folded edge 222, and the sealing effect is achieved by squeezing the sealing body using the buckling surfaces of the drying tunnel upper shell 211 and the fan upper shell 26.

[0129] In some embodiments of the present invention, Figure 11 As shown, the drying tunnel upper shell 211 and the fan upper shell 26 are respectively provided with a plurality of first connection structures 217 for connecting with the lower shell; the fan upper shell 26 is also provided with a plurality of second connection structures 218 for connecting with the clothing processing drum 10 of the wall-mounted clothing processing device.

[0130] In the above embodiment, the second connecting structure 218 secures the laundry treatment drum 10 while also compressing the lower housing. If the first connecting structure 217 between the upper fan housing 26 and the lower housing becomes loose, the second connecting structure 218 still provides the compressive force to prevent the lower housing from loosening. If the second connecting structure 218 becomes loose, the first connecting structure 217 still maintains its function, ensuring the sealing of the fan housing 25 is not affected. This shows that the dual-functional connecting structure of the present invention improves the overall reliability and fault tolerance of the fan housing 25.

[0131] Preferably, the second connecting structure 218 includes a first folding portion formed by folding the edge of the fan upper shell 26 toward the lower shell and a second folding portion formed by extending outward from the end of the first folding portion; the second folding portion is provided with a through hole connected to the clothing processing drum 10.

[0132] It should be noted that the laundry processing tub 10 should be provided with a structure compatible with the second connecting structure 218. For example, when a through hole is provided on the second connecting structure 218, a screw column 11 should be provided on the laundry processing tub 10 to fasten the second connecting structure 218 to the laundry processing tub 10 via screws.

[0133] Preferably, the second connection structure 218 can be led out from the first connection structure 217 .

[0134] In further solutions, such as Figure 12 As shown, a third connection structure 227 for connecting to the clothes processing drum 10 of the wall-mounted clothes processing device is provided on the outer wall of the air guide channel 22 .

[0135] In the above scheme, the air guide channel 22 is arranged on the front side of the clothing processing drum 10. Therefore, a third connecting structure 227 for connecting to the clothing processing drum 10 is arranged on the outer wall of the air guide channel 22, which can improve the stability of the connection between the air guide channel 22 and the clothing processing drum 10 of the present invention.

[0136] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
