Description

Technical Field

[0001] The present application relates to the technical field of clothing washing and care, and in particular to a base device and a clothes drying device. Background Art

[0002] When a heat pump dryer is working, the compressor will work continuously, generating a lot of heat. If the compressor overheats, it will shut down for self-protection and restart after the temperature drops to a certain value. This will increase the drying time. Figures 1 to 3 In order to cool down the compressor 2', a cooling fan 3' is provided near the compressor 2'. When the cooling fan 3' rotates, it draws air from the external environment into the base through the air intake grille 8 in front of the compressor 2' and blows it toward the compressor 2', thereby dissipating heat and cooling the compressor 2'. Figure 3 The arrow direction in the figure indicates the air flow path, but in this solution, the noise radiated outward by the compressor is relatively large; in addition, the air intake grille 8 is arranged in the front, which affects the appearance of the front sealing door 9' and affects the industrial design.

[0003] Due to the need to meet heat dissipation requirements, sound insulation cannot be placed in the airflow path generated by the cooling fan. In related technologies, to reduce noise, the sound wave propagation path is set in a maze form. However, due to the compact structure of the base, there is little free space. Firstly, there is not enough space to set up a maze-like sound wave propagation path. Secondly, the maze-like sound wave propagation path will significantly increase the airflow resistance, resulting in ineffective heat dissipation of the compressor. Summary of the Invention

[0012] In some embodiments, the rotation axis of the cooling fan is arranged parallel to the horizontal plane.

[0013] In some embodiments, the base is provided with a slide groove, and the cooling fan can be inserted into the slide groove from the outside of the base and slide along the slide groove to an installation position.

[0014] In some embodiments, the cooling fan can be inserted into the slide groove from the bottom side of the base, or the cooling fan can be inserted into the slide groove from the front side of the base.

[0015] In some embodiments, the cooling fan is disposed outside the first chamber and is connected to the external environment.

[0016] In some embodiments, the base includes a cover plate and an integrally formed injection-molded body, the injection-molded body is provided with the first chamber and the second chamber, the injection-molded body includes a partition rib located in the second chamber, the partition rib separates the second chamber into an air inlet sub-chamber and a heat exchange sub-chamber, the heat exchange sub-chamber is located on the rear side of the air inlet sub-chamber in the longitudinal direction, the top side of the heat exchange sub-chamber is open, the cover plate closes the opening of the heat exchange sub-chamber, and the top side of the air inlet sub-chamber is open to form an air inlet of the base device.

[0017] In some embodiments, the injection-molded body includes a first bottom wall, a front side wall and a first longitudinal side wall, the front side wall extends along the front side edge of the first bottom wall, the first longitudinal side wall extends along the longitudinal edge of the first bottom wall, the first chamber is located in the area jointly defined by the first bottom wall, the front side wall and the first longitudinal side wall, the end face of the first transverse end of the front side wall is spaced apart from the front end face of the longitudinal side wall to form the opening; the first bottom wall has a support area near the top corner of the opening, the support area is located in the interval space, and the cooling fan is supported on the support area of the first bottom wall.

[0018] In some embodiments, the base includes a limiting plate arranged above the supporting area, the cooling fan is inserted between the supporting area and the limiting plate from the front side of the front side wall, and the cooling fan is fixedly connected to the limiting plate and / or the first bottom wall.

[0019] In some embodiments, the top surface of the support area and the bottom surface of the limiting plate are both provided with sliding grooves, and the top end of the cooling fan and the bottom end of the cooling fan are slidably embedded in the sliding grooves.

[0020] The present application also provides a clothes drying device, including:

[0021] a barrel assembly having a laundry processing chamber;

[0022] A box assembly, wherein the cylinder assembly is arranged in the box assembly;

During the air supply process of the cooling fan, the flow path of the air flow is short and the air volume loss is very small; taking the cooling fan blowing toward the first chamber as an example, the cooling fan draws part of the air in the partition space into the first chamber, and the partition space takes in air from the gap between the base and the ground. Therefore, there is no need to set an air intake grille on the appearance surface of the front side of the box assembly, so that the appearance surface of the front side of the box assembly can maintain good continuity, which can improve the appearance of the drying equipment.

[0028] In addition, the compressor acts as a noise source, and the sound waves generated by the compressor enter the partition space through the opening. Since the front side of the partition space is blocked by the box assembly, the sound waves will not directly pass through the box assembly, but will continue to reflect between the base, the ground, and the box assembly, and the energy will be attenuated. Part of the sound waves will radiate outward from the gap between the base and the ground. At this time, the sound waves radiated outward by the drying equipment are reverberation sounds, and there is no direct sound. The sound wave energy it emits is continuously attenuated due to reflection during the propagation process, which can effectively reduce the noise radiated outward by the drying equipment during operation and improve the user experience.

[0042] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0043] In the description of the embodiments of the present application, the directions or positional relationships of "upper", "lower", "top", "bottom", "longitudinal" and "lateral" are based on the attached drawings. Figure 4 and attached Figure 8 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0044] It should be noted that Figure 4 、 Figure 5 、 Figure 7 as well as Figure 8 The orientation shown is the same.

[0045] An embodiment of the present application provides a base device for use in a clothes drying device.

[0046] See also Figure 4 as well as Figure 5 The base device includes a base, a compressor 2, and a cooling fan 3. The base has a first chamber 101 and a second chamber 102, which are arranged laterally and are independent of each other. A partition 1a is defined between the sidewalls of the first chamber 101 and the sidewalls of the second chamber 102, which is connected to the external environment of the clothes drying apparatus. In other words, this partition 1a is located outside the clothes drying apparatus and is connected to the atmospheric environment. An opening 101a is provided on the sidewall of the first chamber 101 corresponding to the partition 1a, connecting the first chamber 101 with the external environment of the clothes drying apparatus. The compressor 2 is disposed in the first chamber 101, and the cooling fan 3 is disposed at the opening 101a, allowing airflow exchange between the first chamber 101 and the external environment.

[0047] The embodiment of the present application also provides a clothes drying device, including a barrel assembly, a box assembly, a circulation air duct, an evaporator, a condenser, and a base device of any embodiment of the present application. The barrel assembly has a clothing processing chamber and a clothing delivery port, and the user can take clothes in and out of the clothing delivery port. The barrel assembly is arranged in the box assembly; the circulation air duct is connected to the clothing processing chamber; the second chamber 102 is located on the circulation air duct, that is, the airflow in the circulation air duct flows through the second chamber 102, the evaporator and the condenser are located in the second chamber 102, and the evaporator is located upstream of the condenser along the direction of airflow, that is, the airflow first flows through the evaporator and then flows through the condenser. The lower end cover of the box assembly is arranged at the edge of the base, and the box assembly blocks the front side of the partition space 1a and the front side of the first chamber 101. In other words, the airflow will not pass through the part of the box assembly located at the front side of the partition space 1a and the front side of the first chamber 101.

[0048] In the embodiment of the present application, one side along the longitudinal direction is the front side, and the other side along the longitudinal direction is the rear side.

[0049] It should be noted that the evaporator, the condenser and the compressor 2 constitute part of a heat pump system, that is, the clothes drying device in the embodiment of the present application uses heat pump technology to dry clothes.

[0050] The working principle of the heat pump system is as follows: Compressor 2 sucks in low-pressure gaseous refrigerant, which is compressed by compressor 2 and discharged at high pressure. The discharged high-pressure refrigerant enters the condenser, is cooled by the air at room temperature, and condenses into a high-pressure liquid (while transferring heat to the surrounding air). In other words, the air around the condenser will be heated and heated; the high-pressure liquid refrigerant flows through the expansion valve to throttle and reduce pressure, and then becomes a low-pressure, low-temperature gas-liquid two-phase mixture and enters the evaporator. The liquid refrigerant therein evaporates and cools in the evaporator (while absorbing heat from the surrounding air). In other words, the air around the evaporator will be cooled and cooled. The low-pressure gaseous refrigerant produced is again sucked in by compressor 2 and pressurized. This cycle repeats continuously to achieve heat exchange. It should be noted that the above-mentioned expansion valve can also be replaced by a capillary tube.

[0051] The working process and principle of the clothes drying device of the embodiment of the present application are as follows: the dry hot air flow in the circulating air duct enters the clothing processing chamber from the downstream of the circulating air duct along the airflow direction. In the clothing processing chamber, the dry hot air flow flows over the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs moisture from the clothes, and turns into a humid hot air flow. The humid hot air flow enters the second chamber 102 upstream of the circulating air duct and flows through the evaporator and condenser in the second chamber 102 in sequence. In the process of flowing through the evaporator, the humid hot air flow is condensed and dehumidified by the evaporator to form a low-temperature dry air flow. The low-temperature dry air flow is heated to a dry hot air flow when passing through the condenser. The dry hot air flow enters the clothing processing chamber again from the downstream of the circulating air duct, and the cycle continues in this way to achieve continuous and efficient drying of clothes.

[0052] Heat pump drying equipment achieves high energy utilization and low energy consumption. At the same time, the drying temperature of the heat pump system is much lower than the heating temperature of the electric heating element, ensuring the drying quality of clothes.

[0053] It should be noted that the compressor continuously generates heat during operation, resulting in a high surface temperature. The compressor then transfers this heat to the surrounding air, causing the temperature of the first chamber and the surrounding air to rise. During the drying process, the temperature inside the cabinet assembly is relatively high. Therefore, relying solely on natural convection cannot meet the compressor's heat dissipation requirements.

[0054] In the base device of the embodiment of the present application, the hot air in the first chamber 101 is forced to convect with the cold air of the external environment under the action of the cooling fan 3, thereby improving the heat dissipation efficiency; since the cooling fan 3 and the opening 101a are arranged in the separation space 1a, the cooling fan 3 directly transports the hot air flow to the outside of the drying equipment or transports the cold air of the external environment into the first chamber 101. During the air supply process of the cooling fan 3, the flow path of the air flow is short, the air volume loss is small, and the heat exchange efficiency is high.

[0055] It should be noted that when the clothes drying device is placed on the ground, the base is supported on the ground by the supporting legs, that is, there is a certain gap between the bottom surface of the base and the ground.

[0056] Taking the cooling fan 3 blowing toward the first chamber 101 as an example, the cooling fan 3 draws the air in the partition space 1a into the first chamber 101, and the partition space 1a takes in air from the gap between the base and the ground. Therefore, there is no need to set the air intake grille in the related technology on the appearance surface of the front side of the box assembly, so that the appearance surface of the front side of the box assembly can maintain good continuity, which can enhance the appearance of the drying equipment.

[0057] In addition, the compressor 2 acts as a noise source, and the sound waves generated by the compressor 2 enter the partition space 1a through the opening 101a. Since the front side of the partition space 1a is blocked by the box assembly, the sound waves will not directly pass through the box assembly, but will continue to reflect between the base, the ground, and the box assembly, and the energy will be attenuated. The sound waves will eventually radiate outward from the gap between the base and the ground. At this time, the sound waves radiated outward by the drying equipment are reverberation sounds, and there is no direct sound. The sound wave energy it emits is continuously attenuated due to reflection during the propagation process, which can effectively reduce the noise radiated outward by the drying equipment during operation and improve the user experience.

[0058] The specific structural type of the cooling fan 3 is not limited. For example, in the embodiment of the present application, the cooling fan 3 is an axial flow fan, that is, the cooling fan 3 takes in air from one axial side and discharges air from the other axial side.

[0059] The cooling fan 3 can be a blowing fan, that is, the cooling fan 3 blows air toward the inside of the first chamber 101 to allow air in the external environment to flow into the first chamber 101; the cooling fan 3 can also be a suction fan to draw the air in the first chamber 101 into the external environment.

[0060] When the cooling fan 3 is a blower fan, the cooling fan 3 continuously blows air into the first chamber 101. The air in the first chamber 101 can be discharged from the first chamber 101 through the joint between the base and the housing, or the joint between the housing and other structures. When the cooling fan 3 is a suction fan, the cooling fan 3 continuously draws the air in the first chamber 101 into the space 1a. Air from the external environment can be replenished into the first chamber 101 through the joint between the base and the housing, or the joint between the housing and other structures.

[0061] For example, in some embodiments, the cooling fan 3 is a blowing fan, that is, the side of the cooling fan 3 facing the partition space 1a is the air suction side, and the side of the cooling fan 3 facing the first chamber 101 is the air outlet side. In other words, the cooling fan 3 directly blows the relatively low-temperature air in the external environment directly to the first chamber 101, and the low-temperature air can dissipate heat for the compressor 2 in a timely and effective manner.

[0062] It should be noted that the cooling fan 3 should be positioned as close to the compressor 2 as possible to promptly remove the heat generated by the compressor 2 and effectively dissipate heat and cool the compressor 2. For example, in one embodiment, the compressor 2 is located within the air supply range of the cooling fan 3. That is, without the need for any diversion structure, the airflow from the cooling fan 3 can blow directly onto the surface of the compressor 2, i.e., the airflow still has a certain flow rate when it reaches the surface of the compressor 2. The applicant of this application has discovered through careful observation that the heat generation area of the compressor 2 is mainly concentrated in the middle and upper part of the compressor 2. To this end, in some embodiments of this application, the rotation axis of the cooling fan 3 is tilted relative to the horizontal plane and the air is delivered obliquely upward. On the one hand, the cooling fan 3 can blow as much air as possible toward the middle and upper part of the compressor 2, providing more targeted heat dissipation to the heat generation area of the compressor 2. On the other hand, the design dimensions of the base device in the height direction are limited. In this embodiment, while the external dimensions of the cooling fan 3 remain unchanged, the inclined cooling fan 3 requires a smaller installation dimension in the height direction. Therefore, under the same installation height, a larger cooling fan 3 can be used to increase the air volume and improve the heat dissipation effect.

[0063] The inclination angle of the rotation axis of the cooling fan 3 relative to the horizontal plane is not limited. For example, the inclination angle is greater than 0° and does not exceed 35°, for example, 5°, 10°, 15°, 20°, 25°, 30°, 35°, etc. This inclination angle range can take into account the installation dimensions in the height direction while allowing the air flow to directly blow to the upper middle part of the compressor 2.

[0064] It should be noted that the rotation axis of the heat dissipation fan 3 refers to the rotation axis of the blades of the heat dissipation fan 3 .

[0065] In other embodiments, the rotation axis of the heat dissipation fan 3 is arranged parallel to the horizontal plane, that is, the heat dissipation fan is placed approximately vertically.

[0066] It should be noted that there is no limitation on the placement of the cooling fan 3 as long as there is a suitable installation space.

[0067] For example, in some embodiments, in a top projection of the base, the rotation axis of the cooling fan 3 is parallel to the longitudinal direction. It should be noted that in this embodiment, the rotation axis of the cooling fan 3 can be parallel to the horizontal plane or inclined relative to the horizontal plane.

[0068] In other embodiments, in a top projection of the base, the rotation axis of the cooling fan 3 is perpendicular to the longitudinal direction. It should be noted that in this embodiment, the rotation axis of the cooling fan 3 can be parallel to the horizontal plane or inclined relative to the horizontal plane.

[0069] In some further embodiments, in a top-down projection of the base, the rotation axis of the cooling fan 3 is tilted relative to the longitudinal direction and delivers air diagonally rearward. In other words, the rotation axis of the cooling fan 3 forms a certain acute angle with the longitudinal direction, meaning it is neither parallel nor perpendicular. In this embodiment, the cooling fan 3 has a larger space on the air inlet side of the compartment 1a, reducing air inlet resistance while also ensuring that the cooling fan 3 has appropriate installation dimensions in both the longitudinal and transverse directions. The cooling fan 3 can be located inside or outside the first chamber 101, as long as it facilitates airflow.

[0070] For example, in some embodiments, see Figure 9 The cooling fan 3 is disposed outside the first chamber 101 and is connected to the external environment to avoid occupying the space of the first chamber 101 and to avoid interference with the compressor 2. It should be noted that the cooling fan 3 does not extend beyond the front side of the base to avoid interference between the cooling fan 3 and the box assembly.

[0071] The installation method of the cooling fan 3 and the base is not limited, as long as the cooling fan 3 can be fixed on the base. For example, the cooling fan 3 can be fixed on the base by screws, screws, etc.

[0072] For some examples, see Figure 4 and Figure 5 The base is provided with a slide groove 11a, into which the cooling fan 3 can be inserted from the outside of the base and slide along the slide groove 11a to the installation position. Specifically, during the assembly process, the cooling fan 3 can be inserted into the slide groove 11a from the outside of the base. After the cooling fan 3 is slid to the installation position, the cooling fan 3 can be fixed in the installation position by screw connection or other means. The installation process of the cooling fan 3 will not interfere with other components, and the assembly is convenient. The slide groove 11a also serves as a guide and limiter for the cooling fan 3.

[0073] It should be noted that the cooling fan 3 can be inserted into the sliding slot 11 a from any orientation, for example, from top to bottom, from bottom to top, from front to back, etc.

[0074] For example, in some embodiments, the cooling fan 3 can be inserted into the chute 11a from the bottom side of the base. That is, the chute 11a extends generally in the height direction, and the entrance of the chute 11a is located on the bottom side of the base. During assembly, the base is inverted so that the bottom side of the base faces upward, and the cooling fan 3 is inserted into the chute 11a. The cooling fan 3 is then fixedly connected to the base. In this embodiment, the structure of the chute 11a does not affect the structure of the top side of the base, nor does it affect the assembly relationship between the base and the housing assembly.

[0075] In other embodiments, please refer to Figure 5 , Figure 5 The arrow in the figure indicates the direction of insertion of the cooling fan 3. The cooling fan 3 can be inserted into the chute 11a from the front side of the base, and the entrance of the chute 11a is located at the front side of the base. In this embodiment, the structure of the chute 11a does not affect the structure of the top side of the base, nor does it affect the assembly relationship between the base and the housing assembly.

[0076] It should be noted that the cooling fan 3 can be inserted into the chute 11a from front to back, which means that the cooling fan 3 is assembled from the front side of the base, and the cooling fan 3 is inserted into the chute 11a in a direction generally from front to back. In this embodiment, the extension direction of the chute 11a can be parallel to the longitudinal direction or inclined at a certain angle relative to the longitudinal direction.

[0077] For some examples, see Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 as well as Figure 10The base includes a cover plate 12 and an integrally formed injection molded body 11. The injection molded body 11 is provided with a first chamber 101 and a second chamber 102. The injection molded body 11 includes a partition rib 111 located in the second chamber 102. The partition rib 111 separates the second chamber 102 into an air inlet sub-chamber 102a and a heat exchange sub-chamber 102b. The evaporator and condenser are placed in the heat exchange sub-chamber 102b. The heat exchange sub-chamber 102b is located on the longitudinal rear side of the air inlet sub-chamber 102a. The top side of the heat exchange sub-chamber 102b is open. The cover plate 12 closes the opening of the heat exchange sub-chamber 102b. The partition space 1a is located between the first chamber 101 and the air inlet sub-chamber 102a. During the assembly process, after the evaporator and condenser are placed in the heat exchange sub-chamber 102b, the cover plate 12 is closed in the opening of the heat exchange sub-chamber 102b. It should be noted that the joint between the cover plate 12 and the heat exchange sub-chamber 102b should have good sealing performance to reduce the possibility of air leakage.

[0078] See also Figure 7 and Figure 8 The top side of the air inlet sub-chamber 102a is open to form an air inlet 102c of the base assembly. Specifically, the hot and humid airflow in the laundry processing chamber flows downward from the front side of the drum assembly to the air inlet 102c. For example, a first filter assembly (not shown) can be provided near the partition rib 111 of the air inlet sub-chamber 102a to filter impurities such as lint from the airflow exiting the drum assembly.

[0079] For example, see Figure 4 and Figure 5 The front side of the air inlet chamber 102a is open. The air inlet chamber 102a is used to place a second filter assembly (not shown in the figure) to perform secondary filtration on the air entering the heat exchange chamber 102b to prevent lint from entering the evaporator and condenser and affecting the heat exchange efficiency. Figure 6 and Figure 10 The clothes drying apparatus includes a sealing plate 4 that removably seals the opening of the air inlet sub-chamber 102a. During the drying process, the sealing plate 4 seals the front opening of the air inlet sub-chamber 102a to prevent air leakage. To replace or clean the second filter assembly, the sealing plate 4 is removed from the base assembly, the second filter assembly is removed from the opening of the air inlet sub-chamber 102a, and the cleaned second filter assembly is then placed back into the air inlet sub-chamber 102a.

[0080] For some examples, see Figure 4The injection-molded body 11 includes a first bottom wall 112, a front side wall 114 and a first longitudinal side wall 113 extending along the longitudinal direction of the base. The front side wall 114 extends along the front side edge of the first bottom wall 112, and the first longitudinal side wall 113 extends along the longitudinal edge of the first bottom wall 112. The first chamber 101 is located in the area jointly defined by the first bottom wall 112, the front side wall 114 and the first longitudinal side wall 113.

[0081] The end surface of the first transverse end of the front side wall 114 is spaced apart from the front end surface of the first longitudinal side wall 113 to form the above-mentioned opening 101 a . That is, the top corner of the first bottom wall 112 is located outside the first chamber 101 .

[0082] Exemplarily, the top of the front end of the first longitudinal side wall 113 and the top of the first transverse end of the front side wall 114 are connected together by a rib plate, so that the structural strength of the base can be enhanced and the structural reliability of the base can be improved.

[0083] For example, in one embodiment, please refer to Figure 4 The injection molded body 11 includes a second bottom wall 117 and a second longitudinal side wall 116. The second longitudinal side wall 116 extends along the longitudinal edge of the second bottom wall 117. The front end of the first longitudinal side wall 113 and the front end of the second longitudinal side wall 116 are spaced apart. The front end of the first bottom wall 112 and the front end of the second bottom wall 117 are spaced apart. The spacing space 1a is located between the first longitudinal side wall 113 and the second longitudinal side wall 116.

[0084] It should be noted that the portions of the first longitudinal side wall 113 and the second longitudinal side wall 116 located outside the partition space 1 a may be combined into one.

[0085] See also Figure 4 and Figure 11 The first bottom wall 112 has a support area 112 a at a top corner near the opening 101 a . The support area 112 a is located in the spacing space 1 a . The cooling fan 3 is supported on the support area 112 a of the first bottom wall 112 .

[0086] It should be noted that, because compressor 2 is relatively large in height, the space at the top corner of the first bottom wall is left vacant in the related art. Furthermore, in the related art, the fan is positioned directly in front of the compressor, occupying a relatively large space, which results in a smaller vertical dimension of the first chamber and a smaller effective space for component placement. In the embodiment of the present application, cooling fan 3 fully utilizes the space at the top corner of first bottom wall 112, thereby increasing the effective space of first chamber 101.

[0087] For some examples, see Figure 4The base includes a limiting plate 115 disposed above the support area 112a. The cooling fan 3 is inserted between the support area 112a and the limiting plate 115 from the front side of the front side wall 114. The cooling fan 3 is fixedly connected to the limiting plate 115 and / or the first bottom wall 112. The limiting plate 115 fixes the top of the cooling fan 3, and the first bottom wall 112 fixes the bottom of the cooling fan 3.

[0088] The specific structure of the limiting plate 115 is not limited, as long as it can facilitate the positioning and connection of the top of the cooling fan 3.

[0089] For some examples, see Figure 4 The top surface of the support area 112a and the bottom surface of the limiting plate 115 are both provided with a slide groove 11a. The top end of the cooling fan 3 slides in engagement with the slide groove 11a on the limiting plate 115, while the bottom end of the cooling fan 3 slides in engagement with the slide groove 11a on the support area 112a. It should be noted that the "sliding engagement" refers to the sliding engagement of the cooling fan 3 with the corresponding slide groove 11a during assembly.

[0090] It should be noted that the specific structure of the sliding groove 11 a is adapted according to the contour shape of the cooling fan 3 .

[0091] For example, see Figure 4 The top of the cooling fan 3 has two rib edges 31 spaced apart along the axial direction, and the bottom of the cooling fan 3 has two rib edges 31 spaced apart along the axial direction. The top surface of the support area 112a is provided with two slide grooves 11a, and the limiting plate 115 is provided with two slide grooves 11a. During the assembly process, each rib edge 31 slides in the corresponding slide groove 11a.

[0092] For some examples, see Figure 6 、 Figure 8 as well as Figure 10 The cabinet assembly includes a cabinet body and an integrally formed front door 9. The cabinet body is generally U-shaped, with an open front. The front door 9 is positioned within the open portion of the cabinet body and covers the front of the first chamber 101 and the front of the partition space 1a. This ensures a consistent appearance and enhances the aesthetics of the laundry processing device.

[0093] It should be noted that the front sealing door 9 is provided with an avoidance opening at the position of the sealing plate 4 to avoid the sealing plate 4.

[0094] For some examples, see Figure 8The base device also includes a motor 51, a wind wheel 52 and a pulley 53. The motor 51 is arranged in the first chamber 101, and the wind wheel 52 is arranged outside the first chamber 101 and is located on the circulating air duct downstream of the first chamber 101. The motor 51 drives the wind wheel 52 to rotate. During the rotation of the wind wheel 52, negative pressure is formed in the first chamber 101, and positive pressure is formed in the circulating air duct downstream of the wind wheel 52.

[0095] The pulley 53 is rotatably disposed on the outer casing of the motor 51, and the motor shaft of the motor 51 drives the pulley 53 to rotate through a first belt. In this embodiment, the motor 51 has a dual motor shaft, one of which drives the wind wheel 52 to rotate, and the other motor shaft drives the pulley 53 to rotate. The pulley 53 drives the cylinder assembly to rotate through a second belt. Specifically, the second belt is wound around the circumference of the cylinder assembly and between the pulley 53.

[0096] When the clothes drying device is drying clothes, the motor 51 can simultaneously drive the wind wheel 52 and the pulley 53 to rotate, and the pulley 53 drives the drum assembly to rotate. During the rotation of the drum assembly, the clothes are turned over and shaken in the clothes processing chamber, which can accelerate the heat exchange between the clothes and the dry hot air flow.

[0097] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0098] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
