Description

Technical Field

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

[0002] For clothes processing equipment with drying function, the fan and the horizontal drying duct with a heating tube are arranged on the upper part of the outer drum, and the longitudinal drying duct connects the horizontal drying duct and the adapter of the inner drum. The longitudinal drying duct is generally inserted into the channel provided on the front structure of the outer drum. In order to avoid air leakage between the longitudinal drying duct and the channel provided on the front structure of the outer drum, a seal is generally provided between the longitudinal drying duct and the channel provided on the front structure of the outer drum.

[0003] For example, Chinese patent application number CN201920648614.9 discloses a drying duct sealing structure and a wall-mounted washing machine, including a front outer barrel and a drying duct. The front outer barrel is provided with a flange on the side facing away from the washing cavity, and an air inlet is provided on the side of the flange. An air outlet is provided at the lower part of the drying duct, and the air outlet is directly and sealedly connected to the air inlet.

[0004] Then, although the above solution can solve the problem of air leakage between the longitudinal drying air duct and the channel provided on the front structure of the outer cylinder, it requires additional sealing members, which are difficult to fix.

[0005] A Chinese patent application number CN201920423864.2 discloses a washer-dryer, comprising a front outer barrel; a door sealing ring, the door sealing ring being mounted on the front outer barrel, the door sealing ring having an air guide portion, an air inlet portion being formed on the front outer barrel, the air guide portion being passed through the air inlet portion; a drying duct assembly, the drying duct assembly comprising a drying duct body having an air outlet; a transfer tube, one end of the transfer tube being connected to the air outlet of the drying duct body, the other end of the transfer tube being connected to the air inlet portion, the end of the air guide portion being pressed between the other end of the transfer tube and the air inlet portion.

[0006] In the above solution, the door seal ring is used as a seal between the longitudinal drying air duct and the channel provided on the front structure of the outer drum, which simplifies the seal's fixing structure. However, in this solution, the door seal ring is used as a section of the pipeline before the hot air enters the inner drum. This exposes the door seal ring to high-temperature hot air for a long time, which will inevitably degrade its performance and age, and it will lose its sealing function.

[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 clothing processing device. By inserting the air guide channel into the second channel formed on the window pad and at least flush with the end of the second channel, the second channel on the window pad serving as a sealing structure will not be directly impacted by hot air, thereby avoiding aging of the material of the second channel serving as a sealing structure and thus affecting its sealing function.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0010] A clothes processing device comprising

[0011] A laundry processing drum having a laundry access opening, wherein the laundry access opening is provided with a first passage communicating with the interior of the laundry processing drum;

[0012] a window gasket comprising an annular body and a second channel extending from the annular body, the annular body covering the clothing access opening, the second channel being inserted into the first channel;

[0013] An air guide channel is arranged on the front side of the clothing processing drum, one end of the air guide channel is inserted into the second channel, and the end of one end of the air guide channel is at least flush with the end of the second channel close to the clothing access port.

[0014] Furthermore, at least a section of the outer wall of the air guide channel inserted into the second channel is contracted along the second channel away from the clothing access opening toward the second channel close to the clothing access opening.

[0015] Furthermore, at least a portion of one end of the second channel away from the clothing access opening is provided with an outward folding portion, and one end of the first channel away from the clothing access opening is in contact with and connected to the folding portion.

[0016] Furthermore, the folding portion includes a first flange and a second flange connected to each other;

[0017] The side wall of the second channel, the first flange and the second flange together form an embedded portion of a groove-shaped structure;

[0018] One end of the first channel away from the clothing access opening is inserted into the embedded portion;

[0019] Preferably, the first flange is extended outward from the end of the second channel along its radial direction, and the second flange is extended from the end of the first flange along the axial direction of the second channel toward a side close to the clothing access opening.

[0020] Furthermore, one end of the air guide channel is interference fit with the second channel.

[0021] Furthermore, a first fixing structure is provided on the front side of the clothes processing drum, and a second fixing structure is provided on the outside of the air guide channel;

[0022] A fixing connection piece is provided between the first fixing structure and the second fixing structure.

[0023] Furthermore, a reinforcement portion for increasing strength is provided on at least a section of the inner wall of the air guide channel that is inserted into the second channel.

[0024] Furthermore, the reinforcement portion is a reinforcing rib connecting opposite side walls.

[0025] Furthermore, an end portion of one end of the air guiding channel close to a side wall of the clothes processing drum has a projection on a side wall away from the clothes processing drum.

[0026] Furthermore, it also includes a door body for opening and closing the clothing access opening;

[0027] An end portion of one end of the air guide channel is in contact with the door body at a side away from the clothes processing tub.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0029] 1. The present invention prevents the drying hot air from directly impacting the side wall of the second channel, which can protect the second channel to a certain extent. The second channel as a sealing structure on the window gasket will not be directly impacted by the hot air, thus preventing the aging of the second channel material as a sealing structure and thus affecting its sealing function.

[0030] 2. The present invention sets the outer wall of at least a section of the air guide channel extending into the second channel to be contracted, that is, the air guide channel is in an inverted trumpet shape along the flow direction of the drying hot air, which facilitates the insertion of the air guide channel into the second channel.

[0031] 3. The present invention provides an outward folding portion at least partially on a side of the second channel away from the clothing access opening. When the air guide channel is inserted into the second channel, the folding portion can grip the end of the cover shell and will not shift as the air guide channel is inserted.

[0032] 4. When the air guide channel of the present invention is assembled, an interference space appears between the air guide channel and the second channel. External force is used to press the air guide channel against the second channel, and the elasticity of the second channel is fully utilized to fix the air guide channel.

[0033] 5. The present invention utilizes the structure formed between the longer side wall and the shorter side wall to guide the dry hot air naturally into the interior of the clothing processing drum, thereby increasing the effective air intake, simplifying the assembly structure of the clothing processing equipment, and improving assembly efficiency.

[0056] 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

[0057] 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.

[0058] 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.

[0059] 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.

[0060] like Figures 1 to 15 As shown, the present invention provides a clothes processing device, including a clothes processing drum 100 , a window pad 200 and an air guide channel 300 .

[0061] The laundry processing drum 100 has a laundry access opening 105 for placing laundry into or taking laundry out of the laundry processing drum 100 . A first passage 104 communicating with the interior of the laundry processing drum 100 is provided at the laundry access opening 105 .

[0062] As a preferred embodiment of the present invention, Figures 2 to 5 As shown, the laundry treatment tub 100 includes an outer tub 101 and an inner tub 102 rotatably disposed in the outer tub 101 , and the first channel 104 is directly communicated with the interior of the inner tub 102 .

[0063] The window gasket 200 includes an annular body 201 and a second channel 202 formed by the annular body 201 extending outward. The annular body 201 covers the clothing access opening 105, and the second channel 202 is inserted into the first channel 104. When the door body 400 closes the clothing access opening 105, the annular body 201 acts as a seal between the clothing access opening 105 and the door body 400. Figure 9 shown.

[0064] The function of the air guide channel 300 is to introduce drying hot air into the clothes processing drum 100. The air guide channel 300 is arranged at the front side of the clothes processing drum 100. Figure 5 and Figure 8 As shown, one end of the air guide channel 300 is inserted into the second channel 202, and the other end of the air guide channel 300 is connected to the source of drying hot air, and the end of one end of the air guide channel 300 is at least flush with the end of the second channel 202 close to the clothing access port 105.

[0065] In the above solution, the first channel 104 provides a space for the air guide channel 300, allowing the dry hot air to enter the clothing access opening 105 from the front side of the laundry processing drum 100 and then enter the interior of the laundry processing drum 100. The second channel 202 actually serves as a seal between the first channel 104 and the air guide channel 300, allowing the dry hot air to fully enter the laundry processing drum 100 without leaking through the gap between the first channel 104 and the air guide channel 300.

[0066] When the air guide channel 300 of the present invention is extended into the second channel 202, one end of the air guide channel 300 is at least flush with the end of the second channel 202 close to the clothing access port 105. In this way, when the drying hot air enters the interior of the clothing processing drum 100 from the air guide channel 300, it will not directly impact the second channel 202, that is, it will not directly contact the second channel 202.

[0067] Since the window gasket 200 is made of a flexible material such as rubber, and the second channel 202 is generally integrally formed with the annular body 201, the second channel 202 is also generally made of a rubber material. The present invention prevents the drying hot air from directly impacting the sidewalls of the second channel 202, thereby protecting the second channel 202 to a certain extent. This prevents the second channel 202, which serves as a sealing structure on the window gasket 200, from being directly impacted by the hot air, thus preventing aging of the material of the second channel 202, which could affect its sealing function.

[0068] In some implementations of the present invention, Figures 10 to 12 As shown, at least a section of the outer wall of the air guide channel 300 inserted into the second channel 202 is contracted along the side of the second channel 202 away from the clothing access opening 105 toward the side of the second channel 202 close to the clothing access opening 105.

[0069] As previously mentioned, one end of the air guide duct 300 of the present invention is inserted into the second passage 202 and extends to a position at least flush with the end of the second passage 202 near the door body 400. Therefore, to facilitate the insertion of the air guide duct 300 into the second passage 202, the outer wall of at least the section of the air guide duct 300 extending into the second passage 202 is configured to be constricted. In other words, the air guide duct 300 forms an inverted bell-shaped shape along the flow direction of the drying hot air.

[0070] It should be noted that the cross-sectional shape of the air guiding channel 300 should match the cross-sectional shapes of the second channel 202 and the first channel 104 so that the second channel 202 can fit tightly between the air guiding channel 300 and the first channel 104 .

[0071] In one embodiment, the present invention only limits the outer wall of at least a section of the air guide channel 300 extending into the second channel 202 to be contracted. Therefore, the inner wall of the air guide channel 300 maintains a straight cylindrical structure, which can achieve the purpose of easy insertion without reducing the cross-sectional area of the air guide channel 300, and thus will not reduce the amount of air entering the clothing processing drum 100, thereby improving the drying rate.

[0072] Detailed, such as Figure 12 As shown, a section of the pipe of the air guide channel 300 inserted into the second channel 202 is the air outlet 307. The outer wall of the air outlet 307 is retracted inward by a certain wall thickness, and a shoulder structure is formed on the outer wall of the air outlet 307 and the outer wall of the upper main body of the air guide channel 300. When the air outlet 307 is inserted into the second channel 202, the shoulder structure can play a limiting role.

[0073] In another embodiment, the present invention configures the air guide channel 300 as a whole to be contracted along the flow direction of the drying hot air, making it easier to insert the air guide channel 300 into the second channel 202 .

[0074] The above two embodiments can also be used in combination, so as to form a shoulder structure on the outer wall of the air outlet 307 and make the air outlet 307 as a whole have a contracted structure.

[0075] In the above solution, the longitudinal cross-section of the air guiding channel 300 is in the shape of an inverted trapezoid along the flow direction of the drying hot air, while the transverse cross-section of the air guiding channel 300 is in the shape of a rectangle.

[0076] Detailed, such as Figure 10As shown, the air guide channel 300 includes a first side wall 303, a second side wall 304, a third side wall 305, and a fourth side wall 306, which are connected in sequence. The first side wall 303 and the third side wall 305 are arranged opposite each other, while the second side wall 304 and the fourth side wall 306 are arranged opposite each other. The widths of the first side wall 303 and the third side wall 305 are smaller than the widths of the second side wall 304 and the fourth side wall 306. In the present invention, the second side wall 304 and the fourth side wall 306, which have larger widths, are arranged in a contracted structure along the flow direction of the drying hot air, while the first side wall 303 and the third side wall 305, which have smaller widths, are arranged in a nearly parallel structure along the flow direction of the drying hot air. This gives the air guide channel 300 an overall thin wedge-shaped structure, facilitating its insertion into the second air duct.

[0077] In some embodiments of the present invention, Figure 5 and Figure 8 As shown, at least a portion of the second channel 202 at one end away from the clothing access opening 105 is provided with an outward folding portion 203 , and the first channel 104 at one end away from the clothing access opening 105 is in contact with and connected to the folding portion 203 .

[0078] Specifically, the laundry treatment drum 100 includes an outer drum 101 and an inner drum 102. The outer drum 101 has an open front end, which is sealed by an outer drum front structure 103. The first channel 104 is provided on the outer drum front structure 103. In a preferred embodiment, the first channel 104 is formed on the outer drum front structure 103.

[0079] That is, a cover is provided on the outer cylinder front structure 103 , and the inner wall of the cover and the outer wall of the outer cylinder front structure 103 together form the first channel 104 .

[0080] Since the air guide channel 300 of the present invention needs to be inserted to at least the end of the second channel 202 close to the clothing access opening 105, in other words, the air guide channel 300 of the present invention needs to be inserted into the second channel 202 for a longer length. Moreover, the assembly order of the air guide channel 300 is later and the assembly order of the second channel 202 is earlier. Therefore, during the assembly process, it is easy for the assembled second channel 202 and the annular body 201 to shift from their original positions during the insertion of the air guide channel 300. In summary, in order to avoid the displacement of the second channel 202 and the annular body 201 during the assembly and insertion process, the present invention is provided with an outward folding portion 203 on at least part of the side of the second channel 202 away from the clothing access opening 105, that is, the folding portion 203 is provided at least at a position that cooperates with the cover shell, so that the end of the cover shell away from the clothing access opening 105 conflicts with the folding portion 203. In this way, when the air guide channel 300 is inserted into the second channel 202 , the folded portion 203 can grip the end of the housing and will not shift as the air guide channel 300 is inserted.

[0081] In some embodiments of the present invention, the folding portion 203 includes a first flange 205 and a second flange 206 connected to each other; the side wall of the second channel 202, the first flange 205 and the second flange 206 together constitute an embedded portion 204 with a groove-shaped structure; the end of the first channel 104 away from the clothing access port 105 is inserted into the embedded portion 204.

[0082] Specifically, the cross-section of the folded portion 203 is shaped like a "┐" (┐). Therefore, the sidewalls of the second channel 202 and the folded portion 203 together form a recessed insert 204, forming an inverted "U" shape. When the window gasket 200 is assembled, the end of the cover is inserted into the recessed portion 204 through the opening of the recessed portion 204. In other words, the recessed structure of the recessed portion 204 tightly encases the upper end of the cover that forms the first channel 104, preventing the second channel 202 from being displaced by the air guide channel 300, thereby ensuring a consistently good seal at the connection between the air guide channel 300 and the first channel 104.

[0083] In a specific embodiment, the first flange 205 is extended outward from the end of the second channel 202 along its radial direction, and the second flange 206 is extended from the end of the first flange 205 along the axial direction of the second channel 202 toward the side close to the clothing access port 105.

[0084] Furthermore, the inner side surface of the second flange 206 can be configured as an inclined structure to reduce the size of the opening of the embedded portion 204. Generally, the folded portion 203 and the second channel 202 are integrally formed and are also made of a rubber material. When the opening of the embedded portion 204 is reduced, the opening of the embedded portion 204 is tightened to the upper end of the housing like a tie, further preventing displacement.

[0085] Furthermore, an escape portion cooperating with the folding portion 203 is provided on the outer side of the cover. When the groove-shaped structure of the embedded portion 204 tightly wraps the upper end of the cover constituting the first channel 104, the end of the second flange 206 can be located in the escape portion, so that the fixing effect is better.

[0086] In some embodiments of the present invention, Figures 3 to 8 As shown, one end of the air guide channel 300 is connected to the second channel 202 by interference fit.

[0087] In detail, since a folded portion 203 capable of wrapping the end of the cover constituting the first channel 104 is provided at the end of the second channel 202, the air guide channel 300 cannot achieve direct contact connection with the first channel 104, thereby causing problems affecting the fixation of the air guide channel 300.

[0088] The present invention provides an interference fit between the air guide channel 300 and the second channel 202. That is, a certain amount of external force is required to insert the air guide channel 300 into the second channel 202. Specifically, when the air guide channel 300 is assembled, an interference space is created between the air guide channel 300 and the second channel 202. External force is used to press the air guide channel 300 against the second channel 202, fully utilizing the elasticity of the second channel 202 to secure the air guide channel 300.

[0089] In the above solution, inserting the air guide channel 300 into the end of the second channel 202 can prevent the drying hot air from directly impacting the second channel 202 and causing aging of the second channel 202, thereby utilizing the elasticity of the second channel 202 to achieve the purpose of fixing the second channel 202. It can be seen that the above solutions of this aspect complement each other.

[0090] In further solutions, such as Figure 1 and Figure 2 As shown, a first fixing structure 106 is provided on the front side of the laundry processing drum 100 , and a second fixing structure 302 is provided on the outside of the air guide channel 300 ; a fixing connector is provided between the first fixing structure 106 and the second fixing structure 302 .

[0091] Specifically, the air guide channel 300 is a hollow pipe structure enclosed by a first sidewall 303, a second sidewall 304, a third sidewall 305, and a fourth sidewall 306. A second fixing structure 302, such as a lug with a through hole, is disposed on the exterior of each of the first and third sidewalls 303, 305. Preferably, the second fixing structure 302 is positioned midway between the first and third sidewalls 303, 305 along the direction of the hot drying air flow. Simultaneously, a first fixing structure 106, such as a lug with a screw hole, is disposed on the front side of the laundry treatment drum 100, i.e., the outer drum front structure 103, at a position matching the position of the second fixing structure 302.

[0092] When assembling the air guide channel 300, first insert the air guide channel 300 into the second channel 202, then match the position of the second fixing structure 302 with the first fixing structure 106, and then use the fastening screws to fasten the first fixing structure 106 and the second fixing structure 302 to further fix the air guide channel 300.

[0093] It should be noted that the above-mentioned lugs and columns are only one embodiment of the technical solution of the present invention, and all other technical solutions that can achieve a relatively fixed connection between the air guide channel 300 and the clothing processing drum 100 are within the protection scope of the present invention.

[0094] Optionally, there may be multiple first fixing structures 106 and second fixing structures 302 , for example, two, disposed on the left and right sides of the air guide channel 300 , which is beneficial for improving the fixing effect between the air guide channel 300 and the outer cylinder front structure 103 .

[0095] In some embodiments of the present invention, Figures 6 to 8 As shown, a reinforcement portion for increasing strength is provided on at least a section of the inner wall of the air guide channel 300 that is inserted into the second channel 202 .

[0096] In detail, as mentioned above, the air guide channel 300 extends at least to the end of the second channel 202, and the air guide channel 300 is subjected to a high frequency of hot and cold shocks at its air outlet 307. In addition, the air guide channel 300 is generally made of hard plastic material. Therefore, in order to prevent the material of the air guide channel 300 from stretching or shrinking and deforming under the action of frequent hot and cold shocks, thereby affecting the assembly strength and the air volume, the present invention provides a reinforcement part on the inner wall of the air outlet 307 of the air guide channel 300 for strengthening the strength of the air guide channel 300.

[0097] In a specific embodiment, a reinforcing rib 301 is provided between the second side wall 304 and the fourth side wall 306 of the air guide channel 300. The reinforcing rib 301 is generally provided in the middle of the second side wall 304 and the fourth side wall 306. Since the width of the second side wall 304 and the fourth side wall 306 is relatively large, that is, the span of the second side wall 304 and the fourth side wall 306 is relatively large, deformation is likely to occur in the middle portion. Placing the reinforcing rib 301 in the middle position can play a role in supporting the second side wall 304 and the fourth side wall 306. Figure 10 shown.

[0098] It should be noted that the reinforcing rib plate 301 is also susceptible to frequent impacts of hot and cold air. Therefore, the reinforcing rib plate 301 should have a certain strength, at least greater than the strength of the side wall of the air guide channel 300.

[0099] In some embodiments of the present invention, Figure 12 As shown, an end portion of one end of the air guiding channel 300 close to a side wall of the laundry processing drum 100 has a projection on a side wall away from the laundry processing drum 100 .

[0100] In other words, the length of one end of the air guiding channel 300 away from the laundry processing drum 100 is greater than the length of one end of the air guiding channel 300 close to the laundry processing drum 100 .

[0101] In detail, in order to reduce the heat loss of the drying hot air, the drying hot air should be directly introduced into the interior of the clothing processing drum 100 as much as possible. Therefore, in the prior art, a transfer pipe is provided at the air outlet 307 of the air guide channel 300. The transfer pipe is an elbow-shaped structure, one end of which is connected to the air guide channel 300, and the other end faces the interior of the clothing processing drum 100, so that the drying hot air can directly enter the clothing processing drum 100 without contacting the door body 400, thereby reducing heat loss and improving drying efficiency.

[0102] However, although the above-mentioned solution of adding a transfer pipe solves the problem of heat loss of the drying hot air, it also increases the assembly structure of the clothing processing device, reduces the assembly efficiency, and increases the cost of the clothing processing device.

[0103] Therefore, the present invention abandons the structure of setting a transfer tube in the prior art, and directly inserts the air outlet 307 of the air guide channel 300 into the position of the annular body 201. At the same time, the length of the end of one end of the air guide channel 300 away from the clothing treatment drum 100 is set to be greater than the length of the end of one end of the air guide channel 300 close to the clothing treatment drum 100, that is, the length of the second side wall 304 is greater than the length of the fourth side wall 306. The structure formed between the longer side wall and the shorter side wall is used to guide the drying hot air naturally into the interior of the clothing treatment drum 100, thereby increasing the effective air intake. Figures 4 to 8 shown.

[0104] The above solution of the present invention simplifies the assembly structure of the clothing processing device and improves the assembly efficiency.

[0105] In further solutions, such as Figures 6 to 8 As shown, it also includes a door body 400 for opening and closing the clothing access opening 105; the end of one end of the air guide channel 300 is in contact with the door body 400 away from the side of the clothing processing drum 100.

[0106] In detail, the door body 400 has an inclined surface. When the door body 400 is closed, the side of the air guide channel 300 away from the clothing processing drum 100 contacts the door body 400. The side wall of the air guide channel 300 with a longer length and the inclined surface of the door body 400 actually constitute an air guide part with an "Λ"-shaped structure that guides the drying hot air into the interior of the clothing processing drum 100.

[0107] The clothes processing device of the present invention is a washer-dryer, which can be a floor-standing drum-type washer-dryer or a wall-mounted washer-dryer.

[0108] The clothes processing device also includes a fan, a heating device 509, a condenser and other structures that can realize the drying function.

[0109] In some embodiments of the present invention, Figure 14 As shown, the outer side wall of the annular body 201 is used to cooperate with the open end of the structure to be installed, and the outer side wall of the annular body 201 is sequentially provided with a first extension wall 207, a second extension wall 208 and a third extension wall 209 extending outward from one end to the other end; a first installation groove 210 for clamping the open end is formed between the first extension wall 207 and the second extension wall 208, and the end of the third extension wall 209 is provided with a first folding portion 212 folded toward the other end of the annular body 201, and the first folding portion 212 has a second installation groove 211 with an opening toward one end of the annular body 201 and for clamping the open end.

[0110] In the above description, one end of the annular body 201 is the end close to the door 400, and the other end of the annular body 201 is the end close to the inner drum 102. From the perspective of the laundry processing device, the end close to the door 400 is the front end of the annular body 201, and the end close to the inner drum 102 is the rear end of the annular body 201. In the following description, one end of the annular body 201 and the front end of the annular body refer to the end close to the door 400, and the other end of the annular body 201 and the rear end of the annular body 201 refer to the end close to the inner drum 102.

[0111] Specifically, the front end of the annular body 201 is capable of sealingly engaging with the door 400 of the laundry processing device, while its rear end forms a clearance with the front end of the inner drum 102 of the laundry processing device to allow the inner drum 102 to move. Its outer wall is configured to engage with the outer drum front structure 103 of the laundry processing device. Specifically, the annular body 201 fits within the front inner portion of the outer drum 101, with the front and rear ends of the annular body 201 being very close to the door 400 and inner drum 102, respectively. Furthermore, when the door 400 is closed, the window gasket 200 is squeezed against the outer drum 101, sealing it and preventing water from leaking out.

[0112] The present invention enhances the stability of the window gasket 200 by providing a first extending wall 207, a second extending wall 208, and a third extending wall 209 on the outer side of the annular body 201, forming a first mounting groove 210 and a second mounting groove 211 that mate with the open end of the outer cylinder front structure 103. In particular, the second mounting groove 211 opens toward the user. When the user opens the door 400, the second mounting groove 211 firmly engages the outer cylinder front structure 103, preventing the window gasket 200 from falling off the outer cylinder front structure 103 along with the door 400. Furthermore, the second extending wall 208 and the third extending wall 209 give the window gasket 200 an arched structure, increasing its strength and preventing deformation and difficulty in rebounding caused by frequent compression of the observation window glass by the door 400, which could compromise the sealing effect.

[0113] The outer cylinder front structure 103 described in the present invention is a component separately arranged in front of the outer cylinder 101, which can be used to support and fix the window pad 200, and cooperate with the front side of the outer cylinder 101 to form a relatively closed structure, and play a role in shielding part of the structure and beautifying the appearance structure of the clothing processing equipment. It can be understood by referring to the content of the prior art.

[0114] In some embodiments of the present invention, a second folding portion 213 extending outward is provided at the end of the first folding portion 212 , and a plurality of positioning holes 215 are provided on the second folding portion 213 at intervals along the circumferential direction.

[0115] Correspondingly, a positioning structure 1033 for inserting into the positioning hole 215 is also provided on the outer cylinder front structure 103. When assembling the window gasket 200, the positioning hole 215 can be first placed on the positioning structure 1033 and then subsequent assembly steps can be carried out, which can avoid the window gasket 200 from being misaligned during the assembly process.

[0116] In addition, after the window gasket 200 is assembled with the outer cylinder front structure 103, the sleeve connection relationship between the positioning hole 215 and the positioning structure 1033 can further improve the stability of the window gasket 200, thereby preventing the window gasket 200 from being pulled off when the door body 400 of the clothing processing equipment is opened, thereby affecting the sealing effect.

[0117] In some embodiments of the present invention, a third folding portion 214 extending inward is provided at the end of the first folding portion 212, and the third folding portion 214 and the surface of the first folding portion 212 enclose a foreign matter receiving groove 216; the third folding portion 214 is provided with a water guide hole 217 for draining water in the foreign matter receiving groove 216.

[0118] During operation, foreign objects, such as coins, pins, and buttons, can easily fall from the lower half of the inner drum 102 into the gap between the inner and outer drums 102 and 101. Therefore, it is understood that the third folded portion 214 need not extend along the circumference of the annular body 201; it only needs to cover the lower half. However, the existing window gasket 200 structure fails to block foreign objects, making it difficult to address the problems of foreign objects such as coins, pins, and buttons easily falling into the gap between the inner and outer drums 101, causing noise or drainage blockage. To address this technical issue, the third folded portion 214 is extended inward from the end of the first folded portion 212. Together, the third folded portion 214 and the upper surface of the first folded portion 212 define a foreign object receiving groove 216 with a receiving cavity. If the laundry contains small objects such as coins, pins, and buttons, these small objects will be trapped in the foreign object receiving groove 216.

[0119] Although the above solution solves the problem of noise or drainage blockage caused by foreign matter falling into the gap between the inner and outer drums 101, while intercepting the foreign matter, part of the washing water will inevitably be trapped in the foreign matter receiving tank 216. If this part of the washing water cannot be drained in time, bacteria will breed over time, affecting the cleaning effect of the clothing processing equipment.

[0120] Therefore, this embodiment further provides a water guide hole 217 on the third folded portion 214 to guide the retained wash water. It is understood that the size of the water guide hole 217 should not be too large to prevent small objects from passing through the water guide hole 217 and entering the gap between the inner and outer drums 101, thereby weakening the effectiveness of the foreign matter receiving groove 216. It is also understood that the water guide hole 217 should be located at a low position and the number is not limited to one.

[0121] It can be seen that this embodiment solves the problem of foreign matter falling without causing the problem of washing water being trapped.

[0122] In a further solution, a water collecting groove 218 is provided on the inner side wall of the annular body 201 , and the water collecting groove 218 is communicated with the foreign matter receiving groove 216 .

[0123] Specifically, when the door 400 of the laundry processing apparatus is closed, the inner sidewall of the annular body 201 and the glass observation window of the door 400 are in the same radial direction. Since there is a clearance gap between the window gasket 200 and the inner drum 102, it can be seen that during the washing process, wash water will still splash onto the inner sidewall of the annular body 201 through the clearance gap. Therefore, the present invention provides a sump 218 on the inner sidewall of the annular body 201 to collect splashed wash water, and connects the sump 218 to the foreign matter receiving groove 216. When wash water splashes onto the inner sidewall of the annular body 201, it flows into the sump 218 under the action of gravity, then into the foreign matter receiving groove 216, and finally into the outer drum 101 through the water guide hole 217.

[0124] In some embodiments of the present invention, the water collection trough 218 is a groove arranged at a low position of the annular body 201, and the outlet of the water collection trough 218 is located at the other end of the annular body 201, and the bottom wall of the water collection trough 218 is inclined outward from one end of the annular body 201 to the other end, so as to facilitate the introduction of washing water into the foreign matter holding tank 216.

[0125] In addition, a water-sealing rib 219 is provided on the inner wall of the annular body 201, and the water-sealing rib 219 extends toward the observation window of the door body 400. When the door body 400 of the clothing processing device is closed, the water-sealing rib 219 and the observation window of the door body 400 have an interference fit, and the sealing effect is good to prevent water leakage and seepage.

[0126] It can be understood that the above-mentioned water collecting tank 218 is arranged on the inner wall of the annular body 201 and is located on the rear side of the water sealing rib 219.

[0127] In other embodiments of the present invention, Figure 9As shown, the annular body 201 is composed of a first body and a second body connected to each other, the diameter of the first body is larger than the diameter of the second body; the first body is provided with a water sealing rib 219 extending inward, and the water sealing rib 219 and the second body are arranged to form the water collecting trough 218; the second body is provided with a water guiding channel 220, one end of the water guiding channel 220 is connected to the water collecting trough 218, and the other end is connected to the foreign matter receiving groove 216.

[0128] In detail, both the first and second bodies are annular in structure, forming a stepped structure. A water-sealing rib 219 is provided on the first body. Together with the sidewalls of the second body, the water-sealing rib 219 forms a water collection trough 218, which collects wash water splashed onto the inner sidewall of the annular body 201. Furthermore, a water guide channel 220 is provided between the water collection trough 218 and the foreign matter receiving groove 216. Wash water splashed onto the inner sidewall of the second body of the annular body 201 collects in the water collection trough 218, where it is then guided into the foreign matter receiving groove 216 by the water guide channel 220, ultimately entering the outer tub 101 through the water guide hole 217.

[0129] In the above solution, the annular body 201 is configured as a stepped structure, which further increases the strength of the window gasket 200 .

[0130] In some embodiments of the present invention, the outer side wall of the annular body 201 is provided with a plurality of reinforcing ribs 221 connecting the second extension wall 208 and the third extension wall 209 .

[0131] As mentioned above, Figure 1 As shown, the present invention provides a first extension wall 207, a second extension wall 208, and a third extension wall 209 extending outward on the outer sidewall of the annular body 201. The outer sidewall of the annular body 201 is assembled with the outer cylinder front structure 103. When the door 400 is closed, the annular body 201 of the window gasket 200 is pressed toward the outer cylinder front structure 103. To enhance the radial strength of the annular body 201, the present invention provides a reinforcing rib 221 on the outer sidewall of the annular body 201, connecting the second extension wall 208 and the three sidewalls.

[0132] A plurality of reinforcing ribs 221 are evenly spaced apart along the circumference of the annular body 201 , and the reinforcing ribs 221 extend along the axial direction of the annular body 201 .

[0133] The cross section of the reinforcing rib 221 is an inverted trapezoidal structure, that is, the end connected to the outer wall of the annular body 201 is thicker, and the end away from the annular body 201 is thinner.

[0134] In some embodiments of the present invention, the first extension wall 207 includes a first folded edge, a second folded edge, and a third folded edge.

[0135] One end of the first folded edge is connected to the annular body 201; one end of the second folded edge is connected to the other end of the first folded edge; one end of the third folded edge is connected to the other end of the second folded edge; an annular mounting groove 222 for mounting a clamp is provided at the turning connection between the second folded edge and the third folded edge.

[0136] Detailed, such as Figure 9 As shown, the first extension wall 207 includes a first folded edge and a second folded edge. The outer side wall of the annular body 201, the first folded edge, the second folded edge and the third extension wall 209 are sequentially connected on the outer side of the annular body 201 to form a first mounting groove 210 with a right-angled cross-section. A second mounting plate 1032 is correspondingly provided on the outer cylinder front structure 103. During assembly, the second mounting plate 1032 is inserted into the first mounting groove 210 to assemble the window gasket 200 on the outer cylinder front structure 103. The assembly method is simple and convenient, and the structure is simple and easy to process and form.

[0137] Furthermore, the front end of the first folded edge is provided with an annular retaining groove for inserting and mating with the annular ridge provided on the door body 400. The annular retaining groove provided at the front end of the first folded edge is adapted to the annular ridge provided on the door body 400. After assembly, the annular ridge on the door body 400 is embedded in the annular retaining groove, which effectively compresses the window gasket 200 axially, pressing the window gasket 200 tightly against the outer cylinder 101. This not only effectively improves the stability and reliability of the window gasket 200, but also effectively improves the sealing reliability of the window gasket 200, significantly reducing the risk of water leakage at the door body 400.

[0138] Furthermore, an annular mounting groove 222 for mounting a clamp is provided at the turning point between the second folded edge and the third folded edge. After assembly, the clamp can exert effective radial compression on the window gasket 200, pressing the window gasket 200 tightly against the outer tube 101, thereby further improving the stability and reliability of the window gasket 200 and further improving the sealing reliability of the window gasket 200, thereby significantly reducing the risk of water leakage at the front sealing door.

[0139] In some embodiments of the present invention, the outer cylinder front structure 103 includes a first mounting plate 1031 and a second mounting plate 1032 , and the first mounting plate 1031 and the second mounting plate 1032 are interference-fitted with the first mounting groove 210 and the second mounting groove 211 , respectively.

[0140] In detail, the outer cylinder front structure 103 has an open end, and the first mounting plate 1031 and the second mounting plate 1032 are ring-mounted structures disposed at the open end.

[0141] In some embodiments of the present invention, the clothes processing apparatus further includes a drying tunnel body 500 , and the heating device 509 is disposed in the drying tunnel body 500 .

[0142] like Figure 15 As shown, the drying tunnel body 500 comprises an interlocking upper shell 501 and a lower shell 502. The outer wall of the lower shell 502 is flat at its air outlet, while the upper shell 501 is curved at its air outlet. The air guide duct 300 has an outwardly folded edge at the end of the air inlet. The outer wall of the lower shell 502 is sealed to a portion of the folded edge 308 of the air guide duct 300, while the end of the upper shell 501 is sealed to the end face of the remaining folded edge 309 of the air guide duct 300.

[0143] Specifically, using the example of a drying tunnel body 500 positioned above the laundry treatment drum 100 of a laundry treatment apparatus, the curved surface structure of the drying tunnel upper shell 501 is formed by a flat surface bent downward. The outer wall of the drying tunnel lower shell 502 is flat at the air outlet. In other words, the sidewalls of the drying tunnel lower shell 502 do not curve downward. In other words, the air outlet of the drying tunnel body 500 does not have an elbow structure.

[0144] The folded edge at one end of the air inlet of the air guide channel 300 is formed by folding the end of the air inlet outward. Part of the folded edge 308 is used to connect to the lower shell 502 of the drying tunnel, and the other part of the folded edge 308 is used to connect to the end of the upper shell 501 of the drying tunnel.

[0145] In specific plans, such as Figure 13 As shown, when the air guiding channel 300 is connected to the clothes processing drum 100 , the second side wall 304 is close to the clothes processing drum 100 , and the fourth side wall 306 is away from the clothes processing drum 100 .

[0146] The first side wall 303, the second side wall 304, the third side wall 305, and the fourth side wall 306 are all folded outward to form hems. Therefore, the hem corresponding to the second side wall 304 is the partial hem 308, which is connected to the drying tunnel lower shell 502. The hems corresponding to the first side wall 303, the third side wall 305, and the fourth side wall 306 are the remaining hems 309, which are connected to the drying tunnel upper shell 501.

[0147] When the drying tunnel body 500 is assembled with the air guide channel 300, the drying tunnel lower shell 502 is first sealed and connected with part of the folded edge 308 of the air guide channel 300, and then the drying tunnel upper shell 501 is sealed and connected with the remaining folded edge 309 of the air guide channel 300, and then the drying tunnel upper shell 501 is buckled and connected with the drying tunnel lower shell 502.

[0148] In the above solution, by configuring the drying tunnel body 500 as a separate structure consisting of an upper drying tunnel shell 501 and a lower drying tunnel shell 502, and connecting the upper drying tunnel shell 501 and the lower drying tunnel shell 502 to the air inlet of the air guide duct 300, 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 500 and the air guide duct 300, facilitating installation. Furthermore, the air outlet of the drying tunnel body 500 does not need to be designed as a nearly 90° elbow, reducing the manufacturing difficulty of the drying tunnel body 500. This improves the product qualification rate of the drying tunnel body 500, reduces the cost of the drying assembly, and improves the overall market competitiveness of the clothing processing equipment.

[0149] In other words, the structure of the drying tunnel body 500 of the present invention and the connection method between it and the air guide channel 300 are essentially that the outer wall surface of the drying tunnel lower shell 502 and the partial folded edge 308 of the air guide channel 300 form a surface sealing connection, and the drying tunnel upper shell 501 is connected with the drying tunnel lower shell 502 and the remaining folded edge 309 of the air guide channel 300 by snapping.

[0150] In addition, the above connection structure can also improve the sealing performance between the drying tunnel body 500 and the air guide channel 300.

[0151] In some embodiments of the present invention, the surface of the partial folded edge 308 formed by the folding of the second side wall 304 is lower than the surface of the remaining folded edge 309 formed by the folding of the remaining side walls, forming a mounting space for the air outlet portion of the drying tunnel lower shell 502. The drying tunnel lower shell 502 includes a bottom wall and side walls. After the bottom wall of the drying tunnel lower shell 502 is connected to the folded edge of the second side wall 304, the upper edge of the side wall at the air outlet of the drying tunnel lower shell 502 is flush with the surface of the folded edge formed by the folding of the first side wall 303, the third side wall 305, and the fourth side wall 306. In other words, the mating surface of the drying tunnel lower shell 502 and the drying tunnel upper shell 501 should remain flush with the surface of the remaining folded edge 309.

[0152] The above solution can increase the space at the junction of the drying tunnel body 500 and the air guide channel 300, thereby preventing the heated air from forming vortices there, which would affect the air intake efficiency.

[0153] In some specific embodiments of the present invention, the sealing connection between the outer wall surface of the drying tunnel lower shell 502 and the partial folded edge 308 of the air guide channel 300 includes the following three solutions.

[0154] In the first solution, a sealing gasket installation groove 310 is provided on the surface of the partial folded edge 308 , a sealing gasket 315 is provided in the sealing gasket installation groove 310 , and the outer wall surface of the drying tunnel lower shell 502 and the sealing gasket installation groove 310 jointly squeeze the sealing gasket 315 .

[0155] Preferably, a recessed sealing gasket installation groove 310 is provided on the surface of the partial folded edge 308, so that the sealing gasket 315 is embedded in the sealing gasket installation groove 310. When the drying duct lower shell 502 and the air guide channel 300 are assembled, the sealing gasket 315 can be installed in place, and then the drying duct lower shell 502 and the partial folded edge 308 are fixedly connected to squeeze the sealing gasket 315. At the same time, the buckling surface of the drying duct lower shell 502 is flush with the surface of the remaining folded edge 309, thereby ensuring the integrity of the installation surface of the drying duct lower shell 502 and the remaining folded edge 309, and further improving the sealing performance.

[0156] In the second solution, a lower sealing gasket installation groove 310 is provided on the surface of the partial folded edge 308, and an upper sealing gasket installation groove 310 is provided on the outer wall surface of the drying tunnel lower shell 502. The lower sealing gasket installation groove 310 and the upper sealing gasket installation groove 310 together constitute a sealing gasket installation groove 310, and a sealing gasket 315 is provided in the sealing gasket installation groove 310.

[0157] This solution differs from the first solution in that a sealing gasket installation groove 310 for installing a sealing gasket 315 is provided on both the surface of the partial folded edge 308 and the outer wall surface of the drying tunnel lower shell 502. When assembling the drying tunnel lower shell 502 and the air guide duct 300, the sealing gasket 315 can be installed in any of the sealing gasket installation grooves 310. The drying tunnel lower shell 502 is then fixedly connected to the partial folded edge 308, squeezing the sealing gasket 315 while simultaneously aligning the engagement surface of the drying tunnel lower shell 502 with the surface of the remaining folded edge 309. This ensures the integrity of the mounting surface between the drying tunnel lower shell 502 and the remaining folded edge 309, further improving sealing performance.

[0158] In a third solution, a sealing gasket installation groove 310 is provided on the outer wall surface of the drying tunnel lower shell 502 , a sealing gasket 315 is provided in the sealing gasket installation groove 310 , and the sealing gasket installation groove 310 and the surface of the partial folded edge 308 jointly squeeze the sealing gasket 315 .

[0159] This solution differs from the first solution in that a sealing gasket installation groove 310 for mounting a sealing gasket 315 is provided on the outer wall surface of the drying tunnel lower shell 502. When assembling the drying tunnel lower shell 502 and the air guide duct 300, the sealing gasket 315 can be installed in the sealing gasket installation groove 310, and then the drying tunnel lower shell 502 is fixedly connected to the partial folded edge 308, squeezing the sealing gasket 315 while simultaneously aligning the engagement surface of the drying tunnel lower shell 502 with the surface of the remaining folded edge 309. This ensures the integrity of the mounting surface between the drying tunnel lower shell 502 and the remaining folded edge 309, further improving sealing performance.

[0160] In a further solution, the drying tunnel lower shell 502 is provided with a first fastening structure at its air outlet, and the partial folded edge 308 is provided with a second fastening structure 312 , and the first fastening structure and the second fastening structure 312 are connected.

[0161] In detail, in order to further improve the sealing performance between the drying tunnel body 500 and the air guide channel 300, after the sealing gasket 315 is squeezed, the drying tunnel lower shell 502 and the partial folded edge 308 need to be connected with fasteners to make them relatively fixed, and the integrity of the installation surface of the drying tunnel lower shell 502 and the remaining folded edge 309 can be ensured.

[0162] In a preferred embodiment, the first fastening structure is a protruding lug on the sidewall of the drying tunnel lower shell 502, with screw holes provided in the lug. Similarly, the second fastening structure 312 is a fixing plate extending further from the folded edge of the air guide duct 300, also with screw holes provided in the fixing plate. After the drying tunnel lower shell 502 and the partial folded edge 308 of the air guide duct 300 are properly assembled, the lug and fixing plate are tightened with screws.

[0163] In some embodiments of the present invention, the drying tunnel upper shell 501 is provided with a first positioning structure 504 at its air outlet, and the remaining folded edge 309 of the air guide channel 300 is provided with a second positioning structure 313, and the first positioning structure 504 is connected to the second positioning structure 313.

[0164] Specifically, the drying tunnel body 500 is generally irregular in shape, and therefore, misalignment may occur when assembling the drying tunnel lower shell 502 and the air guide channel 300. The present invention provides positioning structures 1033 on both the drying tunnel lower shell 502 and the air guide channel 300. During assembly, the positioning structures 1033 are first used to determine the approximate positional relationship between the drying tunnel lower shell 502 and the air guide channel 300 before proceeding to the next assembly step. This ensures that the drying tunnel lower shell 502 and the air guide channel 300 are assembled without misalignment, improves assembly accuracy, and further enhances sealing performance, thereby preventing hot air from leaking at the connection between the drying tunnel body 500 and the air guide channel 300. This ensures the thermal efficiency of the hot air and improves the drying energy efficiency of the clothing processing device.

[0165] There are three implementation schemes for the above-mentioned buckling connection of the drying tunnel upper shell 501, the drying tunnel lower shell 502 and the remaining folded edge 309 of the air guide channel 300.

[0166] In the first solution, an upper sealing groove is provided on the contour line of the upper fastening surface of the drying tunnel upper shell 501; a first lower sealing groove is provided on the contour line of the upper fastening surface of the drying tunnel lower shell 502, and a second lower sealing groove is provided on the contour line of the remaining folded edge 309. The second lower sealing groove and the first lower sealing groove 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.

[0167] In a preferred embodiment, ribs are provided on the fastening surface of the drying tunnel upper shell 501 to form an upper sealing groove, ribs are provided on the fastening surface of the drying tunnel lower shell 502 to form a first lower sealing groove, and ribs are provided on the surface of the remaining folded edge 309 to form a second lower sealing groove. The first and second lower sealing grooves work together to form the complete lower sealing groove. When assembling the drying tunnel upper shell 501, the drying tunnel lower shell 502, and the air guide duct 300, the sealing body can be first installed in either the upper or lower sealing groove. The drying tunnel upper shell 501, the drying tunnel lower shell 502, and the air guide duct 300 are then fastened together to squeeze the sealing body and achieve a sealing effect.

[0168] In the second solution, an upper sealing groove is provided on the contour line of the fastening surface of the drying tunnel upper shell 501; the fastening surface of the drying tunnel lower shell 502 and the surface of the remaining folded edge 309 are planar structures; a sealing ring is provided in the upper sealing groove, and the upper sealing groove, the fastening surface of the drying tunnel lower shell 502 and the surface of the remaining folded edge 309 jointly press the sealing ring.

[0169] The difference between this solution and the first solution is that only the upper sealing groove is provided on the buckling surface of the drying tunnel upper shell 501, and the buckling surface of the drying tunnel lower shell 502 and the surface of the remaining folded edge 309 are used to jointly extrude the sealing body to achieve a sealing effect.

[0170] In the third solution, a lower sealing groove is provided on the surface of the buckling surface of the lower shell 502 of the drying tunnel and the surface of the remaining folded edge 309 along the contour line; the surface of the buckling surface of the upper shell 501 of the drying tunnel is a planar structure; a sealing ring is provided in the lower sealing groove, and the lower sealing groove and the buckling surface of the upper shell 501 of the drying tunnel jointly press the sealing ring.

[0171] The difference between this solution and the first solution is that the lower sealing groove is only provided on the buckling surface of the drying tunnel lower shell 502 and the surface of the remaining folded edge 309, and the buckling surface of the drying tunnel upper shell 501 is used to squeeze the sealing body to achieve the sealing effect.
