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 relates to a clothing processing device equipped with the drying system. Background Art

[0002] With the progress of society and the advancement of science and technology, people's demands for a higher quality of life are increasing. As common household appliances, clothing handling devices are also subject to increasing expectations. Consequently, the functions of clothing handling devices are becoming increasingly comprehensive and diverse, and their size is shrinking. Among these, clothing handling devices that can dry washed clothes are popular because they are well-suited to rainy and humid weather and shorten the drying time of clothes. Furthermore, due to the significant increase in market demand for ultra-thin clothing handling devices, achieving the maximum washing capacity within a smaller body is also a key development direction for clothing handling devices.

[0003] A clothing processing device with a drying function generally includes a drying system and a drum module disposed within the housing of the clothing processing device. The drum module is mounted within the housing via a shock absorber, and the drying system is connected to the drum module. Conventionally, the drying system includes an air duct and a heat pump system. The condenser and evaporator of the heat pump system are disposed within the air duct, while the compressor is disposed outside the air duct. In existing clothing processing devices, the compressor of the heat pump system is generally disposed behind the drum module, occupying a significant amount of internal space within the housing. For example, Chinese invention patent application number CN201610181823.8 discloses a clothing dryer in which the heat pump unit is integrally disposed below the drum module, and the compressor is disposed below and behind the drum module. Chinese invention patent application number CN201510384704.8 discloses a drying system and clothing drying device in which the air duct and heat pump unit are integrally disposed above the drum module, and the compressor is disposed above and behind the drum module. Such arrangements are not conducive to reducing the overall size of the clothing processing device.

[0004] Therefore, designing a drying system that can ensure the drying effect while making full use of the internal space of the box and avoiding increasing the overall size of the clothes processing equipment has become a technical problem that needs to be solved urgently by those skilled in the art.

[0005] In view of this, the present invention is proposed.

[0060] Example 1

[0061] As shown in FIG. 1 to FIG. 18 , an embodiment of the present invention introduces a drying system 2 , which is applied to a clothes processing device to dry clothes in the clothes processing device.

[0062] The drying system 2 includes an air duct 21, which is arranged above the drum module 1. The air inlet and air outlet ends of the air duct 21 are respectively connected to the drum module 1. A fan 22 is provided on the air duct 21. Under the action of the fan 22, the air flow circulates between the air duct 21 and the drum module 1 to dry the clothes in the drum module 1.

[0063] The air duct 21 is provided with a heating structure 6 and a condensing structure 5. The heating structure 6 heats the air and blows it into the drum module 1. The hot air comes into contact with the clothes in the drum and takes away moisture from the clothes, thereby drying the clothes in the drum module 1.

[0064] As shown in Figures 15 to 18, in this embodiment, the air duct 21 is arranged above the barrel module 1 and installed on the top wall of the box body. The top of the barrel module 1 is provided with an air inlet 11 and an air outlet 12. The air inlet end of the air duct 21 is connected to the air outlet 12 of the barrel module 1, and the air outlet end of the air duct 21 is connected to the air inlet 11 of the barrel module 1.

[0065] The air inlet 11 and air outlet 12 of the barrel module 1 are respectively arranged at the top front end and the top rear end of the barrel module 1, and the air inlet 11 and air outlet 12 are located on both sides of the central axis of the barrel module 1. The air duct 21 is configured as an L-shape. The air duct 21 first extends from the air inlet 11 along the axial direction of the barrel module 1 to the rear end of the barrel module 1, and then extends laterally to connect with the air outlet 12 after extending to be flush with the air outlet 12.

[0178] 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.

[0179] 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.

[0180] 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 .

[0181] 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.

[0182] 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 .

[0183] 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.

[0187] 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.

[0191] 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 .

[0192] Example 4

[0193] 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] 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.

[0200] 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.

[0201] 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.

[0202] 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.

[0203] 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.

[0204] 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 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 has to move the pull-out portion 322 when disassembling and maintaining the filter 31, thereby improving the user experience.

[0205] 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.

[0206] 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.

[0207] 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 .

[0208] 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.

[0209] 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.

[0210] 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 .

[0211] 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.

[0212] 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.

[0213] 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 .

[0214] 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.

[0215] 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.

[0216] Preferably, in this embodiment, the width of the second air duct 212 is less than or equal to the distance between the end of the filter 31 and the front end of the housing 321. Preferably, the diameter of the second gear 3253 is twice the diameter of the first gear 3253.

[0217] In this embodiment, the drawer portion 322 is configured to be plate-shaped, the filter screen 31 is disposed on a first side of the drawer portion 322 , and the transmission device 325 is disposed on a second side of the drawer portion 322 .

When the pull-out portion 322 is pulled out, the filter 31 is pulled out synchronously and accelerated. When the pull-out portion 322 is pulled out to the maximum position, the filter 31 moves to the front end of the pull-out portion 322, and the positioning rib 3222 is inserted into the positioning groove 314.

[0225] Preferably, in this embodiment, a guide opening whose width gradually increases in a direction approaching the positioning rib 3222 is provided at one end of the positioning groove 314 opposite to the positioning rib 3222 , so as to improve the smoothness of the insertion process of the positioning rib 3222 .

[0226] Further preferably, the insertion opening of the positioning rib 3222 and the positioning groove 314 are snap-fitted or interference-fitted, thereby improving the user's feel when pulling the pull portion 322 .
