Description

Technical Field

[0001] The present invention relates to the technical field of clothing washing, drying and the like, and in particular to a drum assembly for a clothing processing device and the clothing processing device. Background Art

[0002] A clothes dryer uses methods such as raising the temperature, lowering the temperature, increasing the airflow speed, and expanding the evaporation area to quickly dry clothes. Existing clothes dryers are generally divided into two categories: direct exhaust type and condensation type. In direct exhaust type machines, hot air is blown into the drum and then directly enters the exhaust pipe through the clothes and is discharged to the outside. In condensation type machines, the internal air circulates in the drum and the air duct. First, after the clothes to be dried are placed in the drum, the warm air generated by the heater is supplied to the drum. The supplied warm air contacts the clothes in the drum and dries the clothes. At this time, the high-temperature and humid air generated by the drying of the clothes first passes through the lint filter in order to remove foreign matter in the air. After that, it enters the air duct through the turbo fan and is introduced into the condenser for steam condensation and cooling, becoming low-temperature and low-humidity air and entering the air duct at the rear of the machine. It is then heated again by the heater and enters the inside of the drum through the drum air inlet. However, the inventor found that the air supply entering the drum could not be adjusted.

[0033] Figure 1 is a schematic structural diagram of a barrel assembly according to an embodiment of the present invention. Figure 1 Shown and referenced Figures 2 to 5, an embodiment of the present invention provides a barrel assembly for a clothing processing device, comprising a rotatable barrel 10 and an air inlet shielding device. An air inlet structure 11 for supplying air to the interior of the barrel 10 is provided on the rear end face of the barrel 10. For example, the air inlet area of ​​the air inlet structure 11 extends along the circumferential direction of the barrel 10, and can extend one circle so as to be connected end to end. Further, the air inlet structure 11 is a plurality of air inlets evenly distributed on the rear end face of the barrel 10. Optionally, the air inlet may be circular, square, triangular, elongated, etc. In some optional embodiments, the air inlet structure 11 is sequentially provided with a plurality of air inlet areas along the circumferential direction of the barrel 10, and a plurality of air inlets are evenly distributed in each air inlet area. Optionally, the plurality of air inlet areas are evenly distributed along the circumferential direction of the barrel 10.

[0034] The air inlet shielding device is disposed on the inner side or the outer side of the rear end surface of the cylinder 10 , and is configured to controllably shield the air inlet structure 11 to change the air supply position and / or air supply area of ​​the air inlet structure 11 .

[0035] In the drum assembly of the embodiment of the present invention, since the air inlet structure 11 is provided on the rear end surface of the drum 10, an air inlet shielding device is also provided. The action of the air inlet shielding device can change the air supply area of ​​the air inlet structure 11, and then change the air supply volume, adjust the air volume entering the drum, and achieve air volume control to improve the clothing treatment effect, such as drying clothes of different types or categories, improving the drying effect, etc. Alternatively, the air supply position can also be changed, for example, under the condition of a determined air supply area, it is determined where in the air supply structure is conductive and where inconductive, so that the clothes in the drum 10 can be reasonably treated.

[0036] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the wind inlet shielding device includes a plurality of stacked wind shields 21, the innermost or outermost wind shield 21 is rotatably arranged relative to the barrel 10 around the central axis of the barrel 10 or fixedly arranged, and each of the remaining wind shields 21 is rotatably arranged relative to the barrel 10 around the central axis of the barrel 10. Any two wind shields 21 are relatively rotatably arranged around the central axis of the barrel 10.

[0037] That is to say, in some optional embodiments, one wind hood 21 is fixedly arranged on the cylinder 10, and the other wind hoods 21 are rotatably arranged. When the air volume needs to be adjusted, the corresponding wind hood 21 is rotated. Further, after the maximum relative rotation of each two adjacent wind hoods 21, the corresponding edges of the two wind hoods 21 are in contact or at least part of the area overlaps, that is, the wind hood 21 can be continuously covered to control the air volume according to demand. In some alternative embodiments of the present invention, after the maximum relative rotation of each two adjacent wind hoods 21, the corresponding edges of the two wind hoods 21 are spaced apart. In other optional embodiments, all the wind hoods 21 are rotatably mounted on the cylinder 10, and the starting position of the wind hood 21 covering can be adjusted relative to the cylinder 10.

[0038] In some embodiments of the present invention, each wind shield 21 has a first edge and a second edge extending in the radial direction of the cylinder 10 to adapt to the structure of the cylinder 10. For example, each wind shield 21 is fan-shaped. The angle between the first edge and the second edge of each wind shield 21 is 20° to 50°, for example, 30°. In order to adapt to different air supply control requirements, the sizes of each two adjacent wind shields 21 can be designed to be equal or unequal.

[0039] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, among every two adjacent wind hoods 21, one wind hood 21 drives the other wind hood 21 to rotate. The innermost or outermost wind hood 21 is fixedly arranged relative to the cylinder 10. The wind inlet shielding device also includes a driving arm 26, which is installed on the outermost or innermost wind hood 21 corresponding to the fixed wind hood 21. The rear end surface of the cylinder 10 can also be referred to as the bottom wall of the cylinder 10. The driving arm 26 drives the wind hood 21 to rotate relative to the cylinder 10, thereby realizing the change of the area covering the rear end of the cylinder 10, that is, the air volume control entering different areas of the cylinder 10 is realized by changing the size of the area covering the bottom wall of the cylinder 10.

[0040] In some embodiments of the present invention, Figure 3As shown, the air inlet shielding device is an integral flexible structure, such as a flexible cover or a foldable wind cover 22, wherein an edge of the flexible cover or the foldable wind cover 22 extending outward from the central axis of the cylinder 10 is rotatably arranged relative to the cylinder 10 around the central axis of the cylinder 10 or fixedly arranged. Another edge of the flexible cover or the foldable wind cover 22 extending outward from the central axis of the cylinder 10 is rotatably arranged relative to the cylinder 10 around the central axis of the cylinder 10. Two edges of the flexible cover or the foldable wind cover 22 extending outward from the central axis of the cylinder 10 are relatively rotatably arranged around the central axis of the cylinder 10. By setting the flexible cover or the foldable wind cover 22, the structure of the air inlet shielding device can be simple, compact and small in size. Further, one edge of the flexible cover or the foldable wind cover 22 extending outward from the central axis of the cylinder 10 is fixed to the cylinder 10, and a driving arm 26 is arranged on the other edge extending outward from the central axis of the cylinder 10.

[0041] In some embodiments of the present invention, Figure 4 As shown, the cylinder assembly also includes a driving device, which is configured to drive the air inlet shielding device to operate so as to controllably shield the air inlet structure 11, thereby changing the air supply position and / or air supply area of ​​the air inlet structure 11.

The clutch mechanism 29 is configured to controllably rotate the second shaft alone, and to rotate the second shaft and the first shaft synchronously. The clothing processing device may have a motor 30, and the motor 30 is used to drive the second shaft. When the drum 10 needs to rotate, the motor 30 drives the second shaft to rotate, and the second shaft drives the first shaft to rotate through the clutch mechanism 29, so that the second shaft and the first shaft rotate synchronously. When the air supply needs to be adjusted, the clutch mechanism 29 rotates the second shaft alone, at which time the air inlet shielding device moves, the drum 10 does not move, and the air inlet shielding device can adjust the air supply. Furthermore, the clutch mechanism 29 may be an electromagnetic clutch mechanism or a mechanical clutch mechanism.

The air inlet shielding device is mounted on the cylinder 10, and the air inlet shielding device includes a plurality of shielding parts, each shielding part is configured to controllably shield an air inlet area to increase or decrease the air supply area of ​​the air inlet area, thereby changing the air supply position and / or air supply area of ​​the air inlet structure 11. Each shielding part may include a plurality of folded and relatively rotatable wind shields, or each shielding part may be a flexible shield or a foldable wind shield.

[0044] In some embodiments of the present invention, the air inlet shielding device can be installed on the stationary structure of the clothing processing device.

Another edge of the flexible cover or the foldable wind shield 22 extending outward from the central axis of the barrel 10 is rotatably arranged around the central axis of the barrel 10 of the stationary structure of the clothing processing device. Two edges of the flexible cover or foldable wind cover 22 extending outward from the central axis of the cylinder 10 are relatively rotatably arranged around the central axis of the cylinder 10 .
