Description

Drying system and clothing processing equipment Technical Field

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

[0002] With the advancement of society and technology, people's demands for a higher quality of life are growing. As common household appliances, clothing handling devices are also attracting higher and higher expectations. Consequently, the functions of clothing handling devices are becoming increasingly comprehensive and diverse. Among them, clothing handling devices that can dry washed clothes are highly popular because they are well-suited to rainy and humid weather and can shorten the drying time of clothes.

[0003] When clothes are dried by a clothing processing device, the circulating airflow will carry the lint shed from the clothes into the drying system. Over time, the lint will clog the drying system (in an electric heating washer-dryer, the lint will get caught in the electric heater and air duct; in a heat pump washer-dryer, the lint will get stuck in the fins), thus affecting the drying efficiency. To solve this problem, a layer (or two layers) of filters are usually installed in the air inlet duct of the drying system to filter out the lint shed from the clothes. To ensure the stability of the drying system, the user needs to maintain the filter and use a pull-out mechanism to pull the filter out and put it in.

[0004] However, to ensure the aesthetics of the clothing processing device, the drawer portion of the drawer mechanism is usually located at the bottom or rear side of the housing. While this arrangement ensures aesthetics, it is very inconvenient for users to disassemble and assemble the device, making it easy for users to forget to clean the filter or install it incorrectly. Therefore, designing a clothing processing device that allows users to easily remove and clean the filter while also ensuring aesthetics has become a technical challenge that those skilled in the art urgently need to solve.

[0005] In addition, the air duct is generally located inside the clothing processing device, with the air outlet of the drum module located at the rear end. The air inlet of the air duct extends to the rear end of the drum module and connects to the air outlet. The filter is placed in the air duct near the air outlet of the drum module. Under this structure, if the filter is to be removed from the side of the box, the user needs to pull it a long distance in the pulling direction, making it difficult to remove and place the filter, which seriously affects the user experience. Therefore, designing a drying system that allows users to easily remove and install the filter has become a technical problem that needs to be solved urgently by those skilled in the art.

[0006] In view of this, the present invention is proposed.

[0128] Example 2

[0129] As shown in FIG. 1 to FIG. 14 , in an embodiment of the present invention, a drying system 2 is introduced. The drying system 2 is applied to a clothes processing device for drying clothes in a drum module 1 of the clothes processing device.

[0130] The drying system 2 is communicated with the drum module 1 of the laundry processing device. Specifically, the drum module 1 includes an inner drum for accommodating laundry to be washed and an outer drum coaxially sleeved outside the inner drum. The drying system 2 is communicated with the outer drum of the drum module 1.

[0131] In this embodiment, the drying system 2 includes a first air duct 211, a second air duct 212 and a fan 22 connected between the first air duct 211 and the second air duct 212. The fan 22 provides power for the flow of the drying airflow. Under the action of the fan 22, the drying airflow flows from the second air duct 212 to the first air duct 211.

[0132] As shown in Figure 1, the outer cylinder is provided with an air inlet 11 for connecting to one end of the first air duct 211 away from the fan 22, and an air outlet 12 for connecting to one end of the second air duct 212 away from the fan 22. The air inlet 11 is arranged at the top front end of the outer cylinder, the air outlet 12 is arranged at the top rear end of the outer cylinder, and the fan 22 is arranged at the upper rear end of the outer cylinder. The setting position of the fan 22 corresponds to the air inlet 11 in the axial direction of the outer cylinder and to the air outlet 12 in the transverse direction. The first air duct 211 is connected between the air inlet 11 of the cylinder module 1 and the air outlet end of the fan 22, and the second air duct 212 is connected between the air inlet end of the fan 22 and the air outlet 12 of the cylinder module 1.

[0133] That is, the air inlet 11 and air outlet 12 are located laterally on either side of the central axis of the drum module 1. The first air duct 211 extends axially along the drum module 1, connecting between the air inlet 11 and the air outlet of the fan 22. The second air duct 212 extends laterally, connecting between the air outlet 12 and the air inlet of the fan 22. When the fan 22 is in operation, air flows out of the air outlet 12 of the drum module 1, passes through the second air duct 212, the fan 22, and the first air duct 211 in sequence, and then returns to the drum module 1.

[0136] By longitudinally arranging the fan 22 on one side above the drum module 1, the drying system 2 can fully occupy the space on both sides above the drum module 1. At the same time, the air duct 21 can be completely placed above the drum module 1, thereby making the layout more compact and reducing the overall size of the clothing processing equipment. In addition, by arranging the top of the fan 22 to be coplanar with the top of the first air duct 211 and the second air duct 212, it is possible to facilitate the installation of the drying system 2 while ensuring a compact structure and improve the working stability of the drying system 2.

Specifically, the air inlet end of the fan 22 is coaxially arranged on the side of the volute opposite to the second air duct 212, and the drive motor is coaxially arranged on the side of the volute opposite to the second air duct 212. The air outlet end of the fan 22 extends along the axial direction of the barrel module 1 toward the front end of the barrel module 1.

[0140] The volute is arranged longitudinally, and the air inlet end of the fan 22 is arranged at the front end top of the volute and extends along the tangential direction of the volute, thereby ensuring that the top of the fan 22 is coplanar with the tops of the first air duct 211 and the second air duct 212.

[0141] In this embodiment, the first air duct 211 and the second air duct 212 both extend in the horizontal direction, and the motor can be arranged in a vertical layout or in an inclined layout, that is, the axis of the impeller forms a certain angle with the horizontal direction.

[0142] In this embodiment, the impeller is coaxial with the volute.

Specifically, the air inlet end of the fan 22 is arranged facing the second air duct 212, and the top surface of the volute is coplanar with the top surfaces of the first air duct 211 and the second air duct 212. After the drying system 2 is installed, the top surface of the fan 22 is aligned with the top inner wall of the cabinet.

[0145] Preferably, in this embodiment, the fan 22 is tilted to the maximum extent that the air inlet end of the fan 22 is directly opposite the center line of the barrel module 1, that is, the angle at which the axis of the air inlet end of the fan 22 extends along the radial direction of the barrel module 1. At this time, the diameter of the volute of the fan 22 can be maximized.

[0146] In this embodiment, the height of the lower end of the fan 22 is less than the height of the top of the drum module 1, and the height of the upper end of the fan 22 is greater than the height of the top of the drum module 1. Specifically, the height of the upper end of the fan 22 is equal to the height of the top surfaces of the first air duct 211 and the second air duct 212. Preferably, in this embodiment, the fan 22 is arranged vertically, or the top of the fan 22 is arranged to be coplanar with the top surfaces of the first air duct 211 and the second air duct 212, so that the top surface of the fan 22 is in contact with the top inner wall of the box, thereby ensuring the stability of the installation of the drying system 2 and reducing the vibration during the operation of the fan 22, making the operation of the drying system 2 more stable.

[0147] Preferably, in this embodiment, the specific configuration of the fan 22 is arranged according to the longitudinal length of the fan 22. If the longitudinal length of the fan 22 is long, or the laundry processing device requires a fan 22 with a longer longitudinal length, the fan 22 can be arranged in an inclined configuration. If the longitudinal length of the fan 22 is short, or the laundry processing device requires a fan 22 with a shorter longitudinal length, the fan 22 can be arranged in a vertical configuration.

[0148] In this embodiment, the longitudinal length of the fan 22 refers to the longitudinal length of the fan 22 when the air outlet end faces forward, that is, the longitudinal length of the fan 22 refers to the diameter of the volute.

[0149] In this embodiment, a guide pipe 23 connected to the air inlet end of the fan 22 is provided at the end of the second air duct 212, the first end of the guide pipe 23 is connected to the end of the second air duct 212, and the second end of the guide pipe 23 is connected to the air inlet end of the fan 22.

[0151] Preferably, in this embodiment, the diameter of the air inlet end of the fan 22 is smaller than the lateral width of the second air duct 212 away from the air outlet 12, and is larger than the longitudinal width of the second air duct 212 away from the air outlet 12. The left and right sides of the guide tube 23 contract smoothly from the first end to the second end, and the upper and lower sides of the guide tube 23 expand smoothly from the first end to the second end.

[0152] Preferably, the widths of the left and right sides of the guide tube 23 that shrink inwardly from the first end to the second end are the same.

[0153] The guide tube 23 bends and extends downward from the first end to the second end. Preferably, the second end of the guide tube 23 is connected to the air inlet end of the fan 22 in a direction perpendicular to the side of the volute near the air outlet 12. By providing the guide tube 23, a compact layout can be ensured while ensuring smooth air flow and preventing airflow turbulence.

[0154] In this embodiment, an opening communicating with the outside is provided on the side of one end of the guide tube 23 close to the fan 22 . The opening is connected to the air outside the air duct 21 and is used to introduce external airflow into the air duct 21 under the action of the fan 22 .

[0155] Preferably, the opening is arranged toward the rear end of the drum module 1 and is connected to the outside of the box through a pipeline. In this embodiment, a vent valve is provided on the pipeline, and the control unit of the laundry processing device can control whether to introduce external airflow by controlling the opening and closing of the vent valve.

[0156] In this embodiment, the second air duct 212 is configured as a split structure, including a main body and an upper cover that interlock with each other, and the air guide tube 23 is configured as an integrated structure. The end of the air guide tube 23 is sleeved on the outside of the end of the second air duct 212 away from the air outlet 12 and is fixed by a pipe clamp to ensure the stability of the overall structure of the second air duct 212. Preferably, the inner wall of the air guide tube 23 smoothly transitions with the inner wall of the end of the second air duct 212 away from the air outlet 12.

[0157] The air outlet end of the fan 22 is arranged toward the front end of the barrel module 1 , and the first air duct 211 extends from the air outlet end of the fan 22 toward the front of the barrel module 1 .

[0158] In this embodiment, the shape of the end of the first air duct 211 away from the air inlet 11 is adapted to the shape of the air outlet end of the fan 22, the top of the volute is flush with the top of the first air duct 211, and the bottom wall and left and right side walls of the end of the first air duct 211 smoothly shrink inward in the direction close to the fan 22.

[0159] Preferably, in this embodiment, the inward contraction amplitude of the side wall of the end portion of the first air duct 211 close to the second air duct 212 is greater than the inward contraction amplitude of the side wall away from the second air duct 212 .

[0160] In this embodiment, a first folded edge extending vertically outward is provided at the port of the first air duct 211 away from the air inlet 11, and a second folded edge extending vertically outward is provided at the air outlet port of the fan 22.

[0161] The first side and the second folded edge can be connected in any manner, such as bolt connection, welding, or snap connection.

[0162] The first folded edge and the second folded edge extend circumferentially along the port of the first air duct 211 and the port of the air outlet end of the fan 22, respectively. Specifically, the first side and the second folded edge are respectively arranged on the left and right sides and the lower side of the port of the first air duct 211 and the air outlet end of the fan 22, so that the top surface of the fan 22 and the first air duct 211 can better fit with the top inner wall of the box.

[0163] Preferably, in this embodiment, a sealing structure is provided between any two joint components of the drying system 2 to ensure the sealing of the drying system 2 as a whole.

[0164] In this embodiment, a heating structure 6 is provided within the first air duct 211, and a condensing structure 5 is provided within the second air duct 212. The dry airflow, powered by the fan 22, circulates between the air duct 21 and the drum module 1. The air is heated by the heating structure 6 and blown into the drum module 1. The hot air, upon contact with the clothes in the drum, removes moisture from the clothes, thereby drying the clothes in the drum module 1. The dry airflow exiting the drum module 1 is condensed and dried by the condensing structure 5. The condensed dry airflow then flows back into the fan 22 and first air duct 211 for a heating cycle.

[0165] A condensed water outlet is provided at the lowest point of the second air duct 212. Condensed water generated on the condensation structure 5 drops into the second air duct 212, flows toward the lowest point of the second air duct 212, and is discharged from the condensed water outlet.

[0166] In some possible embodiments, the condensate outlet is connected to a drainage pipe of the clothes processing device.

[0167] Preferably, in this embodiment, the drying system 2 further includes a filter assembly, which includes a filter screen 31 arranged in the second air duct 212 , and the filter screen 31 is used to filter the lint entering the drying system 2 to prevent the lint from entering the fan 22 .

[0168] Further preferably, in this embodiment, the filter 31 is disposed at an end of the second air duct 212 away from the first air duct 211 .

[0169] Example 3

[0170] As shown in FIG. 1 to FIG. 14 , in an embodiment of the present invention, a drying system 2 is introduced. The drying system 2 is applied to a clothes processing device for drying clothes in a drum module 1 of the clothes processing device.

[0171] The drying system 2 is communicated with the drum module 1 of the laundry processing device. Specifically, the drum module 1 includes an inner drum for accommodating laundry to be washed and an outer drum coaxially sleeved outside the inner drum. The drying system 2 is communicated with the outer drum of the drum module 1.

[0172] The drying system 2 includes an air duct 21, and the drum module 1 is provided with an air inlet 11 and an air outlet 12 for communicating with the air duct 21. Specifically, the air inlet 11 is provided at the top front end of the drum module 1, and the air outlet 12 is provided at the top rear end of the drum module 1. The air inlet 11 and the air outlet 12 are located on either side of the central axis of the drum module 1 in the transverse direction. The air duct 21 includes a first air duct 211 extending rearwardly from the air inlet 11 along the axial direction of the drum module 1, and a second air duct 212 extending transversely from the rear end of the first air duct 211 and connected to the air outlet 12.

[0173] The drying system 2 also includes a filtering device 3, which includes a filter screen 31 arranged in the air duct 21 for filtering hair debris entering the air duct 21. The filter screen 31 is detachably installed in the air duct 21, and the filtering device 3 also includes a pulling mechanism 32 for removing the filter screen 31.

[0174] In this embodiment, the filter 31 is arranged in the air duct on the upper rear side of the barrel module 1 and is taken in and out from the side of the box. If a conventional pulling mechanism is used, the pulling part needs to be pulled out a long distance to pull out the filter. This embodiment improves the pulling mechanism to address this defect.

[0175] Specifically, in this embodiment, the second air duct 212 extends horizontally in the left-right direction at the top rear side of the cartridge module. The filter 31 is disposed within the second air duct 212 and extends in the front-to-back direction. The pull-out portion of the pull-out mechanism is drawn from the front panel of the housing. Conventional pull-out mechanisms require the front end of the pull-out portion to be pulled out the distance between the panel and the rear side of the second air duct in order to remove the filter. This embodiment aims to remove the filter with a shorter pull-out distance.

[0176] In this embodiment, the filter 31 is disposed within the second air duct 212, near one end of the air outlet 12 of the cartridge module 1. The filter 31 is disposed at a certain angle to the extension direction of the second air duct 212, covering the cross-section of the filter 31 along the width direction, so that all airflow passing through the second air duct 212 is filtered by the filter 31. The extension direction of the filter 31 can be perpendicular to the extension direction of the second air duct 212, or it can be non-perpendicular, as long as the projection of the filter 31 can cover the cross-section of the second air duct 212.

[0177] The filter 31 is arranged in the second air duct 212 in a manner that can be pulled out from one side of the second air duct 212. The user can pull out the filter 31 to take it in and put it in. The pulling mechanism 32 is arranged on the side of the second air duct 212 and is connected to the filter 31. Thus, the filter 31 can be pulled out and put in by the pulling mechanism 32.

[0178] Preferably, in this embodiment, the access opening of the filter 31 is arranged at the front side of the second air duct 212, and the user pulls out and takes out the filter 31 from the front end of the clothes processing device.

[0179] Specifically, the pulling mechanism 32 includes a shell 321 and a pulling portion 322 installed in the shell 321. The shell 321 is configured as a strip, extending from the removal port of the filter 31 along the pulling direction of the filter 31. The pulling portion 322 is slidably arranged in the shell 321. The pulling portion 322 is connected to the filter 31, and the pulling portion 322 extends in the shell 321 along the pulling direction of the filter 31. Therefore, the user can pull out and remove the filter 31 through the pulling portion 322 to realize the disassembly, replacement, maintenance and cleaning of the filter 31.

[0180] The existing pull-out portion 322 is generally directly connected to the end of the filter 31. When the user takes out the filter 31, the user needs to first pull out the pull-out portion 322 completely, and then continue to pull out the pull-out portion 322 to pull out the filter 31. The sum of the lengths of the pull-out portion 322 and the filter 31 needs to be pulled out. The disassembly process is very inconvenient, which seriously affects the user experience.

[0181] In this regard, in an embodiment of the present invention, the pull-out portion 322 of the pull-out mechanism 32 is retractable from the end of the housing 321 away from the air duct 21 and is disposed within the housing 321. The pull-out portion 322 is connected to the filter 31 via a transmission device 325. During the pulling process, the pull-out portion 322 drives the filter 31 to slide relative to the pull-out portion 322. In this embodiment, the filter 31 within the air duct 21 is pulled out using the pull-out mechanism 32. By connecting the pull-out portion 322 of the pull-out mechanism 32 to the filter 31 via a transmission device 325, the filter 31 is driven to slide relative to the pull-out portion 322. This allows the user to move the filter 31 in the same direction at a relatively fast speed when moving the pull-out portion 322. This shortens the distance the user must move the pull-out portion 322 when disassembling and maintaining the filter 31, thereby improving the user experience.

[0182] Preferably, in this embodiment, the second air duct 212 is a flat pipe extending horizontally and having a rectangular cross-section. The taking-in and putting-out opening of the filter 31 is opened on the front side of the second air duct 212. The pulling direction of the filter 31 is perpendicular to the extension direction of the second air duct 212, that is, the filter 31 is pulled along the front-to-back direction.

[0183] The shell 321 is arranged on the front side of the second air duct 212 and extends horizontally in the front-to-back direction. The rear port of the shell 321 is connected to the take-in and put-out port on the second air duct 212. The front end of the filter 31 at least partially extends into the shell 321 and is transmission-connected to the pull-out part 322. The pull-out part 322 pulls the filter 31 out of the channel in the shell 321.

[0184] In this embodiment, the pull-out portion 322 is connected to the filter screen 31 through a transmission device 325 . The transmission device 325 is a gear 3253 rack transmission device 325 , which includes a first rack 3251 , a second rack 3252 and a gear 3253 .

[0185] In some possible embodiments, the first rack 3251 is installed on the shell 321 and extends along the pulling direction of the pulling portion 322. The second rack 3252 is installed on the filter 31 and is parallel to the first rack 3251. The first rack 3251 and the second rack 3252 are arranged opposite to each other. The gear 3253 is installed on the pulling portion 322 through a rotating shaft and is arranged between the first rack 3251 and the second rack 3252. The two sides are respectively engaged with the first rack 3251 and the second rack 3252 for transmission.

[0186] Thus, when the user pulls the pull-out portion 322, the gear 3253 rotates under the action of the first rack 3251, and drives the filter 31 to produce a same-direction displacement relative to the pull-out portion 322 through the second rack 3252. That is, during the movement of the pull-out portion 322, the filter 31 is driven by the gear 3253 rack to synchronously produce a faster same-direction displacement, thereby shortening the moving length of the pull-out portion 322 when the user disassembles and maintains the filter 31.

[0187] In this embodiment, the number of the gear 3253 is one. In this case, the moving speed of the filter 31 relative to the housing 321 is twice the moving speed of the drawer 322 relative to the housing 321 .

[0188] Preferably, in this embodiment, the gears 3253 can also be set to be two coaxially arranged and circumferentially limited connected, and the two gears 3253 are respectively engaged with the first rack 3251 and the second rack 3252. Thus, by changing the size of the two gears 3253, the speed difference between the filter 31 and the pull-out part 322 can be changed, that is, the moving speed of the filter 31 relative to the pull-out part 322 can be changed.

[0189] In other possible embodiments, the first rack 3251 of the transmission device 325 is installed on the pulling portion 322 and extends along the pulling direction of the pulling portion 322. The second rack 3252 is installed on the filter 31, parallel to the first rack 3251, and arranged opposite to the first rack 3251. The gear 3253 is installed on the shell 321, including a first gear 3253 and a second gear 3253 coaxially arranged and circumferentially limited, and a third gear 3253 arranged between the first gear 3253 and the first rack 3251, or between the second gear 3253 and the second rack 3252. One of the first gear 3253 and the second gear 3253 is meshed with the first rack 3251 or the second rack 3252 through the third gear 3253, and the other of the first gear 3253 and the second gear 3253 is directly meshed with the first rack 3251 or the second rack 3252.

[0190] In this embodiment, the function of the third gear 3253 is to keep the moving direction of the filter 31 consistent with the moving direction of the drawer 322 .

[0191] Preferably, in this embodiment, the pull-out portion 322 drives the first gear 3253 and the second gear 3253 to rotate synchronously in the first direction through the first rack 3251, the second gear 3253 drives the third gear 3253 to rotate in the second direction, and the third gear 3253 drives the filter 31 and the pull-out portion 322 to move in the same direction through the second rack 3252.

[0192] In this embodiment, the ratio of the diameters of the first gear 3253 and the second gear 3253 is equal to the ratio of the displacement of the pull-out portion 322 relative to the housing 321 and the displacement of the filter screen 31 relative to the housing 321.
