[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0044] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or mutual communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0045] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0046] In the prior art, a ventilation shell is provided at the rear of the dryer. The structure of the ventilation shell is complex and cannot completely cover the messy structure at the rear of the dryer, resulting in an unsightly appearance of the rear side of the clothing processing device. The high-temperature airflow in the ventilation cavity is transmitted to the surface of the dryer through the ventilation shell, resulting in a high surface temperature of the dryer and a high risk of scalding the user, affecting the safety of the dryer during operation. In addition, the dryer cannot effectively isolate the fan noise, which reduces the user's experience of using the dryer.

[0047] To this end, the embodiment of the present invention designs a ventilation shell assembly 10 with a metal cover 3 covering the ventilation shell 2 on the outermost side. Thus, the metal cover 3 is arranged at the rear of the dryer, so that the rear surface of the dryer can have a more beautiful appearance, and the ventilation shell 2 that is in direct contact with the high-temperature airflow is separated from the outside world, reducing the risk of burns during use by users. The metal cover 3 can also be used to effectively isolate the fan noise, thereby achieving noise reduction of the dryer.

[0048] Reference below Figure 1-Figure 7 A ventilating housing assembly 10 of a clothes dryer according to an embodiment of the present invention will be described.

[0049] The ventilation shell assembly 10 of the clothes dryer according to the embodiment of the present invention includes: a support plate 1 , a ventilation shell 2 and a metal cover 3 .

[0050] The ventilation shell 2 and the clothing processing drum assembly are respectively arranged on both sides of the support plate 1. The ventilation shell 2 is arranged on the first side of the support plate 1 in the thickness direction, that is, the rear side of the support plate 1. The clothing processing drum assembly is arranged on the second side of the support plate 1 in the thickness direction, that is, the front side of the support plate 1. The clothing processing drum assembly defines a clothing processing chamber. The base is arranged on the second side of the support plate 1 in the thickness direction, below the clothing processing drum assembly, and defines an air duct. In order to achieve communication between the air duct and the clothing processing chamber, the ventilation shell 2 and the support plate 1 define a ventilation chamber 201. The ventilation chamber 201 is used to connect the clothing processing chamber and the air duct of the dryer. A fan is arranged in the ventilation chamber 201, and the fan can drive the high-temperature airflow in the ventilation chamber 201 from the air duct to the clothing processing chamber. In particular, a lot of noise will be generated during the operation of the fan, and the heat of the high-temperature airflow will also be transferred to the surface through the ventilation shell 2.

[0051] Furthermore, the metal cover 3 is arranged on the first side of the support plate 1 in the thickness direction, that is, the same side of the ventilation shell 2. In other words, the metal cover 3 and the ventilation shell 2 are arranged on the rear side of the support plate 1 at the same time. The metal cover 3 covers the ventilation shell 2 to isolate the ventilation shell 2 from the outside world. On the one hand, it can isolate the noise generated by the operation of the fan inside the ventilation shell 2 to achieve noise reduction of the dryer. On the other hand, it separates the ventilation shell 2 that is in direct contact with the high-temperature airflow from the outside world, reducing the risk of burns during user use.

[0052] Furthermore, the shape of the metal cover 3 is roughly the same as that of the support plate 1. Thus, the metal cover 3 can cover the entire support plate 1, so that the support plate 1 and the structure arranged at the rear of the support plate 1 can be covered inside the metal cover 3, that is, they can be protected by the metal cover 3, avoiding the structure inside the metal cover 3 from being damaged by the external environment, and can also achieve the purpose of unifying the appearance of the rear of the dryer and improving the beauty of the appearance of the rear of the dryer.

[0053] According to the ventilation shell assembly 10 of the clothes dryer in the embodiment of the present invention, the ventilation shell assembly 10 of the clothes dryer improves the aesthetics of the rear appearance of the clothes dryer, reduces the risk of burns during use by users, and achieves noise reduction of the clothes dryer.

[0054] Reference Figure 1 and Figure 2 The ventilation shell 2 and the metal cover 3 are spaced apart, thereby preventing heat from being directly transferred from the ventilation shell 2 to the metal cover 3. The air barrier formed by the direct spacing between the ventilation shell 2 and the metal cover 3 is used to achieve heat insulation, thereby reducing the risk of burns during use by users. In addition, the ventilation shell and the metal cover 3 are spaced apart, which can also prevent the vibration caused by the operation of the wind wheel in the ventilation cavity 201 from being directly transferred to the metal cover 3, thereby achieving vibration isolation and noise reduction.

[0055] In some embodiments, reference Figure 1 and Figure 2A sound insulation material piece 4 is provided between the ventilation shell 2 and the metal cover 3. The sound insulation material piece 4 can directly absorb the noise generated during the operation of the wind wheel between the ventilation shell 2 and the metal cover 3, and can also achieve direct heat insulation between the ventilation shell 2 and the metal cover 3, thereby reducing the risk of burns during use by users and achieving noise reduction of the dryer.

[0056] In some embodiments, the ventilation shell 2 is a plastic part to reduce the weight of the ventilation shell 2 and achieve lightweight dryer. In addition, the plastic part has low thermal conductivity efficiency and has better thermal insulation effect, avoiding heat loss of the airflow in the ventilation cavity 201.

[0057] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, the support plate 1 is fixedly connected to the metal cover 3, so that the metal cover 3 is fixedly supported by the high-strength support plate 1, ensuring the stability of the metal cover 3. In addition, the metal cover 3 can cover the support plate 1 and the structure arranged on the rear side of the support plate 1, ensuring the aesthetics of the rear surface of the dryer.

[0058] Specifically, the support plate 1 is provided with a first connection hole 14, and the metal cover 3 is provided with a first mating hole 34. The support plate 1 and the metal cover 3 are connected by a first fixing member. The first fixing member passes through the first connection hole 14 and the first mating hole 34. The support plate 1 and the metal cover 3 are connected by the first fixing member. This achieves a detachable connection between the metal cover 3 and the support plate 1, reducing assembly difficulty and lowering the maintenance cost of the clothes dryer. Furthermore, the metal cover 3 and the support plate 1 do not require a complex connection structure; they can be connected by simply drilling holes at corresponding positions. This reduces the difficulty of manufacturing the metal cover 3 and the support plate 1, and reduces the production cost of the clothes dryer.

[0059] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The first connecting hole 14 is provided at the edge of the support plate 1, and the first matching hole 34 is provided at the edge of the metal cover 3 to avoid the ventilation shell 2 and other structures provided in the middle of the support plate 1. The edges of the support plate 1 and the metal cover 3 can be fitted together to ensure the stability of the connection between the metal cover 3 and the support plate 1.

[0060] Furthermore, by providing the first matching hole 34 at the edge of the metal cover 3 , the integrity of the overall appearance of the rear side of the metal cover 3 can be ensured, thereby improving the aesthetic appearance of the rear side of the clothes dryer.

[0061] Reference Figure 1 、 Figure 2 and Figure 6A portion of the metal cover 3 extends away from the support plate 1, forming a first recess 35 on the inner wall of the metal cover 3. The ventilated shell 2 is located within the first recess 35. In other words, the first recess 35 and the support plate 1 together define a space for accommodating the ventilated shell 2. The clothes dryer utilizes this space to achieve thermal and sound insulation, reducing the risk of burns during use and achieving noise reduction.

[0062] The edge portion of the metal cover 3 surrounding the first recess 35 is fitted with the support plate 1 , and the first matching hole 34 is opened on the structure of the edge portion of the metal cover 3 , so that the metal cover 3 and the support plate 1 are more tightly connected, ensuring the stability of the connection between the two.

[0063] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 6 The support plate 1 has a limiting protrusion 15 on one side facing the metal cover 3. The setting of the limiting protrusion 15 can not only enhance the strength of the support plate 1, but also cooperate with the metal cover 3 to make the connection between the two tighter.

[0064] Specifically, at least a portion of the side wall of the first recess 35 cooperates with the side wall of the limiting protrusion 15. Thus, the limiting protrusion 15 can cooperate with the side wall of the first recess 35 to limit the metal cover 3, thereby reducing the force exerted on the first fixing part used to connect the support plate 1 and the metal cover 3, and ensuring the stability of the setting of the metal cover 3.

[0065] Moreover, at least a portion of the side wall of the first recess 35 cooperates with the side wall of the limiting protrusion 15, and can also locate the installation position of the metal cover 3 during the installation process of the metal cover 3, thereby reducing the installation difficulty and ensuring the accurate installation position of the metal cover 3.

[0066] Furthermore, at least a portion of the side wall of the first recess 35 cooperates with the side wall of the limiting protrusion 15, which can also improve the sealing of the space defined between the first recess 35 and the support plate 1. Improving the sealing of the space can improve the isolation effect of the metal cover 3 on the noise generated during the operation of the fan inside the ventilation cavity 201, thereby achieving better noise reduction.

[0067] like Figure 1 and Figure 2 As shown, the support plate 1 has a first ventilation area and a second ventilation area arranged at intervals. The first ventilation area corresponds to the clothes processing drum assembly and can connect the ventilation cavity 201 and the clothes processing cavity. The second ventilation area corresponds to the air duct on the base and can connect the air duct and the ventilation cavity 201. The first ventilation area and the second ventilation area are both circular, and the line connecting the center of the first ventilation area and the center of the second ventilation area is inclined relative to the height direction of the metal cover 3.

[0068] Among them, the first ventilation area is provided with a first opening 11, which is used to connect the ventilation cavity 201 and the clothing processing cavity. The second ventilation area is provided with a second opening 12, which is used to connect the air duct and the ventilation cavity 201. Thus, the ventilation cavity 201 is connected with the clothing processing cavity through the first opening 11 and is connected with the air duct through the second opening 12.

[0069] Furthermore, corresponding to the first recess 35, a first protrusion 31 is formed on the outer wall of the metal cover 3. The first protrusion 31 protrudes rearward. The thickness of the first protrusion 31 affects the overall front-to-back thickness of the dryer. To reduce the dryer's size and prevent further increase in thickness, a further structure is provided alongside the first protrusion 31 to prevent it from affecting the space occupied by the dryer in this direction.

[0070] Among them, the first protrusion 31 includes a first side wall 311 and a second side wall 312 arranged opposite to each other. The first side wall 311 and the second side wall 312 are both inclined relative to the height direction of the metal cover 3 and are respectively arranged on both sides of the line connecting the center of the first ventilation area and the center of the second ventilation area, so as to define a space inclined relative to the height direction of the metal cover 3 between the first side wall 311 and the second side wall 312, and the space is provided with a first protrusion 31, and the first protrusion 31 corresponds to the ventilation shell 2 covering the first ventilation area and the second ventilation area.

[0071] The metal cover 3 is formed as a whole in a rectangular shape. The first inclined wall and the edge of the metal cover 3 define a space on the outer wall of the metal cover 3 that is parallel to the first protrusion 31, and the space can be used to install part of the structure of the dryer. The second inclined wall and the edge of the metal cover 3 define another space on the outer wall of the metal cover 3 that is parallel to the first protrusion 31, and the space can be used to install another part of the structure of the dryer. Since the above two parts of the space are parallel to the first protrusion 31, the structure provided in these two parts of the space will not affect the size of the space occupied in the front-to-back direction of the dryer.

[0072] Furthermore, the first protrusion 31 has a simple structure, which facilitates the production and processing of the metal cover 3 and helps to improve the integrity and aesthetics of the rear surface of the dryer.

[0073] Specifically, the first side wall 311 is located above the second side wall 312, that is, the first side wall 311 and the two adjacent edges of the metal cover 3 correspond to the upper corner of the metal cover 3, and the second side wall 312 and the two adjacent edges of the metal cover 3 correspond to the lower corner of the metal cover 3.

[0074] like Figure 5 and Figure 7 As shown, a first mounting portion 32 is provided between the first side wall 311 and two adjacent edges of the metal cover 3 for mounting the winding box 5 .

[0075] The clothes dryer has a power cord, which includes a connected plug and a wiring harness. At least a portion of the wiring harness and the plug of the power cord are stored and limited by the winding box 5.

[0076] Specifically, the winding box 5 is arranged on the first mounting portion 32 and defines a wire harness storage groove 53 between the winding box 5 and the first mounting portion 32. At least a portion of the wire harness is arranged in the wire harness storage groove 53. That is to say, all the wire harnesses of the power cord can be stored in the wire harness storage groove 53, or only a portion of the wire harness can be stored in the wire harness storage groove 53. Different designs can be made according to the layout of the power cord.

[0077] The wire harness storage groove 53 defined between the winding box 5 and the first mounting portion 32 opens to all directions. During the wire harness storage process, part of the wire harness can be wound into the wire harness storage groove 53. During the winding process, the winding box 5 and the first mounting portion 32 stop the wire harness on the inner and outer sides respectively to prevent the wire harness from escaping from the wire harness storage groove 53.

[0078] The winding box 5 includes a main body 51 and a protrusion 52. The protrusion 52 extends in a direction away from the main body 51. The wiring harness is limited by the main body 51 and the first mounting portion 32. The top of the protrusion 52 is connected to the first mounting portion 32. The surfaces of the main body 51 and the first mounting portion 32 are respectively located on both sides of the protrusion 52. Therefore, the setting of the protrusion 52 separates the main body 51 from the outer surface of the first mounting portion 32, and a wiring harness storage groove 53 is defined between the surfaces of the main body 51 and the first mounting portion 32.

[0079] The winding box 5 can store the wiring harness of the power cord, fix the wiring harness of the power cord, avoid damage to the power cord, limit the direction of the wiring harness, and arrange the wiring harness reasonably. Users cannot see the wiring harness from the appearance of the whole machine, which is not only more beautiful, but also avoids the wiring harness arrangement taking up more packaging space, thereby reducing transportation costs.

[0080] The winding box 5 is detachably mounted on the first mounting portion 32 , so that the winding box 5 and the metal cover 3 can be formed separately and then assembled together, which is beneficial to the production and processing of the winding box 5 , reduces production difficulty, and reduces production costs.

[0081] In some embodiments, the winding box 5 is connected to the first mounting portion 32 via a fastener. The winding box 5 also has a plug receiving slot 54. The plug is arranged in the plug receiving slot 54. On the one hand, the plug can be stored to prevent the plug from falling off, being squeezed and deformed, and ensuring the safety of the plug during transportation. On the other hand, the plug is fixed in cooperation with the plug receiving slot 54, that is, the plug end of the power cord is fixed by the plug receiving slot 54, and the other end of the power cord is also fixed. As a result, both ends of the power cord are fixed. During the wiring harness winding process of the power cord, the entire wiring harness is tightened. Since both ends of the power cord are fixed, the wiring harness is always kept in a tightened state. As a result, the wiring harness is not easy to loosen or fall off after being stored.

[0082] Moreover, due to the arrangement of the winding box 5, the external environment is not easy to damage the wiring harness located in the wiring harness storage slot 53 and the plug located in the plug storage slot 54. The winding box 5 can protect the wiring harness from being damaged by the external environment on the outside of the wiring harness, thereby avoiding damage to the wiring harness due to friction during transportation and improving the safety of the power cord during transportation.

[0083] Furthermore, there is a second mounting portion 33 between the second side wall 312 and the two adjacent edges of the metal cover 3 for installing the water flow structure. According to the different structural requirements of the dryer, the second mounting portion 33 can be used to install other structures of the dryer or clothing processing equipment, which is not limited here.

[0084] For a clothing processing device with both drying and washing functions, the second mounting portion 33 can be used to install a water flow structure, which includes a water inlet pipe and a water inlet three-way valve, so as to make the overall structure of the clothing processing device more compact and realize the miniaturization of the clothing processing device.

[0085] Reference Figure 6 The ventilation shell 2 has a volute tongue portion 202, and the projection of the volute tongue portion 202 on the plane where the support plate 1 is located is located between the first ventilation area and the second ventilation area. The shape and size of the volute tongue portion 202 can improve the flow characteristics of the airflow and reduce wind resistance, so that the airflow can flow more smoothly from the second opening 12 to the first opening 11, reducing noise and vibration.

[0086] Since the structure of the volute tongue portion 202 is relatively complex, and the ventilation shell 2 is a plastic part with a simple molding process, the production and processing difficulty of the dryer can be reduced by arranging the volute tongue portion 202 on the ventilation shell 2.

[0087] In some embodiments, the side wall opposite to the volute tongue portion 202 is tangent to the first ventilation area and the second ventilation area at the same time to reduce the airflow resistance and ensure the ventilation performance in the ventilation cavity 201. The first protrusion 31 of the metal cover 3 is set according to the shape of the ventilation shell 2, and the side wall of the ventilation shell 2 opposite to the volute tongue portion 202 is spaced apart from the second side wall 312. Therefore, in order to reserve enough space for the external structure arrangement of the metal cover 3 as much as possible, the side wall of the ventilation shell 2 opposite to the volute tongue portion 202 is inclined in the same direction as the second side wall 312.

[0088] like Figure 1-Figure 3 As shown, the ventilation shell 2 includes an inner shell 21 and an outer shell 22. A ventilation cavity 201 is defined between the inner shell 21 and the support plate 1. The outer shell 22 is sleeved on the outside of the inner shell 21 and has the same contour as the inner shell 21. The outer shell 22 is sleeved on the outside of the inner shell 21 and plays the role of sound insulation and heat insulation outside the inner shell 21, avoiding heat loss of high-temperature airflow flowing inside the ventilation cavity 201, absorbing the noise generated by the operation of the wind wheel, reducing the risk of burns during user use, and realizing noise reduction of the dryer.

[0089] Further, refer to Figures 1-4 and Figure 6 The inner shell 21 and the outer shell 22 are connected by a second fixing member. Specifically, a second connecting hole 211 is provided on the inner shell 21, and a second matching hole 221 is provided on the outer shell 22. The inner shell 21 and the outer shell 22 are connected by the second fixing member. The second fixing member passes through the second connecting hole 211 and the second matching hole 221 to connect the inner shell 21 and the outer shell 22.

[0090] The inner shell 21 and the outer shell 22 are connected via a second fixing member. Only connecting holes need to be provided on the inner shell 21 and the outer shell 22 without the need to design other connecting structures, thereby reducing design and processing costs.

[0091] Furthermore, the shell 22 and the support plate 1 are connected by a third fixing member. Specifically, a third connecting hole 222 is provided on the shell 22, and a third matching hole 13 is provided on the support plate 1. The shell 22 and the support plate 1 are connected by the third fixing member. The third fixing member passes through the third connecting hole 222 and the third matching hole 13 to connect the shell 22 to the support plate 1.

[0092] The inner shell 21 and outer shell 22 are connected via a third fixing member. Only connecting holes need to be provided on the support plate 1 and outer shell 22, eliminating the need for additional connecting structures. This reduces design and processing costs. Furthermore, the inner shell 21 is indirectly connected to the support plate 1 through its connection to the outer shell 22, eliminating the need for a connecting structure between the inner shell 21 and support plate 1, further ensuring the sealing of the ventilation cavity 201.

[0093] According to the second embodiment of the present invention, the clothes processing device is as follows: Figure 8As shown, it includes: a first clothing processing module and a second clothing processing module, the first clothing processing module and the second clothing processing module are stacked, wherein at least one of the first clothing processing module and the second clothing processing module is a dryer and includes the ventilation shell assembly 10 of the dryer of the above embodiment, and the other can be a washing machine.

[0094] Since the outermost rear portion of the ventilation shell assembly 10 of the clothes dryer is provided with a metal cover 3 covering the ventilation shell 2, the metal cover 3 and the rear cover 102 of the washing machine are both made of metal and have a unified appearance, making the appearance of the clothes processing device more beautiful.

[0095] The following combination Figures 1-8 A specific embodiment of a clothes treating apparatus is described.

[0096] The laundry processing apparatus according to an embodiment of the present invention includes: a first laundry processing module and a second laundry processing module.

[0097] like Figure 8 As shown, a first laundry processing module and a second laundry processing module are stacked, with the first laundry processing module stacked above the second laundry processing module. The first laundry processing module is a clothes dryer, and the second laundry processing module is a washing machine. The clothes dryer includes a ventilated housing assembly 10, which includes a metal cover 3. The washing machine includes a rear cover 102. The metal cover 3 and the rear cover 102 are both made of metal and have a unified appearance, making the laundry processing device more aesthetically pleasing.

[0098] The clothes dryer further comprises: a clothes processing drum assembly and a base, and the ventilation shell assembly 10 further comprises: a support plate 1 , a ventilation shell 2 and a winding box 5 .

[0099] The ventilation shell 2 and the clothing treatment drum assembly are respectively arranged on both sides of the support plate 1. The ventilation shell 2 is arranged on the first side of the support plate 1 in the thickness direction, that is, the rear side of the support plate 1. The clothing treatment drum assembly is arranged on the second side of the support plate 1 in the thickness direction, that is, the front side of the support plate 1. The clothing treatment drum assembly defines a clothing treatment chamber. The base is arranged on the second side of the support plate 1 in the thickness direction, below the clothing treatment drum assembly, and defines an air duct. The ventilation shell 2 and the support plate 1 define a ventilation chamber 201, and the ventilation chamber 201 is used to connect the clothing treatment chamber and the air duct of the dryer. A fan is arranged in the ventilation chamber 201, and the fan can drive the high-temperature airflow in the ventilation chamber 201 from the air duct to the clothing treatment chamber. Among them, a lot of noise is generated during the operation of the fan, and the heat of the high-temperature airflow is also transferred to the surface through the ventilation shell 2.

[0100] The metal cover 3 and the ventilation shell 2 are simultaneously arranged on the rear side of the support plate 1. The metal cover 3 covers the ventilation shell 2 to isolate the ventilation shell 2 from the outside world. On the one hand, it can isolate the noise generated by the operation of the fan inside the ventilation shell 2 to achieve noise reduction of the dryer. On the other hand, it separates the ventilation shell 2 that is in direct contact with the high-temperature airflow from the outside world, reducing the risk of burns during user use.

[0101] Furthermore, the shape of the metal cover 3 is roughly the same as that of the support plate 1. Thus, the metal cover 3 can cover the entire support plate 1, so that the support plate 1 and the structure arranged at the rear of the support plate 1 can be covered inside the metal cover 3, that is, they can be protected by the metal cover 3, avoiding the structure inside the metal cover 3 from being damaged by the external environment, and can also achieve the purpose of unifying the appearance of the rear of the dryer and improving the beauty of the appearance of the rear of the dryer.

[0102] The ventilation shell 2 and the metal cover 3 are spaced apart, thereby preventing heat from being directly transferred from the ventilation shell 2 to the metal cover 3. The air barrier formed by the direct spacing between the ventilation shell 2 and the metal cover 3 is used to achieve heat insulation, thereby reducing the risk of burns during use by users. In addition, the ventilation shell and the metal cover 3 are spaced apart, which can also prevent the vibration caused by the operation of the wind wheel in the ventilation cavity 201 from being directly transferred to the metal cover 3, thereby achieving vibration isolation and noise reduction.

[0103] A sound insulation material 4 is provided between the ventilating housing 2 and the metal cover 3. The sound insulation material 4 may be a sound insulation cotton. The sound insulation material 4 not only absorbs noise generated during the operation of the impeller directly between the ventilating housing 2 and the metal cover 3, but also provides direct heat insulation between the ventilating housing 2 and the metal cover 3, reducing the risk of burns during use and achieving noise reduction for the clothes dryer.

[0104] The ventilation shell 2 is a plastic part to reduce the weight of the ventilation shell 2 and achieve lightweight clothes dryer. In addition, the plastic part has low thermal conductivity efficiency and has better heat preservation effect, avoiding heat loss of airflow in the ventilation cavity 201.

[0105] The support plate 1 is fixedly connected to the metal cover 3, so that the high-strength support plate 1 can be used to fix and support the metal cover 3, ensuring the stability of the metal cover 3. In addition, the metal cover 3 can cover the support plate 1 and the structure arranged behind the support plate 1, ensuring the aesthetics of the rear surface of the dryer.

[0106] Specifically, the support plate 1 is provided with a first connection hole 14, and the metal cover 3 is provided with a first mating hole 34. The support plate 1 and the metal cover 3 are connected via a first fixing member. The first fixing member passes through the first connection hole 14 and the first mating hole 34. The support plate 1 and the metal cover 3 are connected via the first fixing member, thereby achieving a detachable connection between the metal cover 3 and the support plate 1. The first connection hole 14 is provided at the edge of the support plate 1, and the first mating hole 34 is provided at the edge of the metal cover 3 to avoid the ventilation shell 2 and other structures provided in the middle of the support plate 1. The edges of the support plate 1 and the metal cover 3 can be arranged in a close fit, ensuring the stability of the connection between the metal cover 3 and the support plate 1. In addition, the first mating hole 34 is provided at the edge of the metal cover 3 to ensure the integrity of the overall appearance of the rear side of the metal cover 3, thereby improving the aesthetics of the rear side of the dryer.

[0107] A portion of the wall of the metal cover 3 extends in a direction away from the support plate 1 to form a first recess 35 on the inner wall of the metal cover 3, and the ventilation shell 2 is located in the first recess 35. The support plate 1 has a limiting protrusion 15 on the side facing the metal cover 3. The setting of the limiting protrusion 15 not only enhances the strength of the support plate 1, but also cooperates with the metal cover 3 to make the connection between the two tighter. At least a portion of the side wall of the first recess 35 cooperates with the side wall of the limiting protrusion 15. Thus, the limiting protrusion 15 can cooperate with the side wall of the first recess 35 to limit the metal cover 3, reducing the force applied to the first fixing member connecting the support plate 1 and the metal cover 3, and ensuring the stability of the metal cover 3.

[0108] Moreover, at least a portion of the side wall of the first recess 35 cooperates with the side wall of the limiting protrusion 15, and can also locate the installation position of the metal cover 3 during the installation process of the metal cover 3, thereby reducing the installation difficulty and ensuring the accurate installation position of the metal cover 3.

[0109] Furthermore, at least a portion of the side wall of the first recess 35 cooperates with the side wall of the limiting protrusion 15, which can also improve the sealing of the space defined between the first recess 35 and the support plate 1. Improving the sealing of the space can improve the isolation effect of the metal cover 3 on the noise generated during the operation of the fan inside the ventilation cavity 201, thereby achieving better noise reduction.

[0110] The support plate 1 has a first ventilation area and a second ventilation area arranged at intervals. The first ventilation area corresponds to the laundry treatment drum assembly and can connect the ventilation cavity 201 and the laundry treatment cavity. The second ventilation area corresponds to the air duct on the base and can connect the air duct and the ventilation cavity 201. The first ventilation area and the second ventilation area are both circular, and the line connecting the center of the first ventilation area and the center of the second ventilation area is inclined relative to the height direction of the metal cover 3.

[0111] Among them, the first ventilation area is provided with a first opening 11, which is used to connect the ventilation cavity 201 and the clothing processing cavity. The second ventilation area is provided with a second opening 12, which is used to connect the air duct and the ventilation cavity 201. Thus, the ventilation cavity 201 is connected with the clothing processing cavity through the first opening 11 and is connected with the air duct through the second opening 12.

[0112] Corresponding to the first recess 35, a first protrusion 31 is formed on the outer wall of the metal cover 3, protruding rearward. The first protrusion 31 comprises a first sidewall 311 and a second sidewall 312, both of which are arranged opposite each other. Both the first sidewall 311 and the second sidewall 312 are inclined relative to the height of the metal cover 3 and are located on either side of a line connecting the centers of the first and second ventilation zones. A first mounting portion 32 is provided between the first sidewall 311 and two adjacent edges of the metal cover 3 for mounting the winding box 5. A second mounting portion 33 is provided between the second sidewall 312 and two adjacent edges of the metal cover 3 for mounting a water flow structure, which includes a water inlet pipe and a three-way water inlet valve.

[0113] The ventilation shell 2 has a volute tongue portion 202, and the side wall of the ventilation shell 2 opposite to the volute tongue portion 202 is spaced apart from the second side wall 312. Therefore, in order to reserve enough space for the external structure arrangement of the metal cover 3 as much as possible, the side wall of the ventilation shell 2 opposite to the volute tongue portion 202 is inclined in the same direction as the second side wall 312.

[0114] The ventilation housing 2 includes an inner housing 21 and an outer housing 22. A ventilation cavity 201 is defined between the inner housing 21 and the support plate 1. The outer housing 22 is sleeved on the outside of the inner housing 21 and conforms to the contour of the inner housing 21. The outer housing 22 sleeves on the outside of the inner housing 21 and provides sound insulation and heat preservation outside the inner housing 21. This prevents heat loss from the high-temperature airflow flowing within the ventilation cavity 201, absorbs noise generated by the operation of the impeller, reduces the risk of burns during user use, and achieves noise reduction of the clothes dryer. The inner housing 21 and the outer housing 22 are connected by a second fixing member. Specifically, the inner housing 21 is provided with a second connecting hole 211, and the outer housing 22 is provided with a second matching hole 221. The inner housing 21 and the outer housing 22 are connected by the second fixing member. The second fixing member passes through the second connecting hole 211 and the second matching hole 221 to connect the inner housing 21 and the outer housing 22. The shell 22 and the support plate 1 are connected by a third fixing member. Specifically, a third connecting hole 222 is provided on the shell 22, and a third matching hole 13 is provided on the support plate 1. The shell 22 and the support plate 1 are connected by the third fixing member. The third fixing member passes through the third connecting hole 222 and the third matching hole 13 to connect the shell 22 to the support plate 1.
