With the improvement of life style, the demand for clothes dryers is gradually rising. When the rear air is fed into the existing drum dryer, the central shaft part of the drum bottom of the drum is used as a supporting part of the drum, the air is usually not fed through holes, and the rear air feeding position usually adopts the holes of concentric circular ring areas at the bottom of the drum. After the hot air of the drum dryer enters the drum from the drum bottom hole, most of the hot air is flushed to the cylindrical inner wall of the drum along the existing inertia, and less hot air is blown to the central shaft part of the drum, so that the clothes at the central shaft part of the drum are dried slowly, and the drying effect of the central and peripheral parts of the drum is uneven.
The utility model provides a roller assembly, which aims to solve the technical problem of how to improve the drying effect of clothes treatment equipment. The drum assembly is applied to a laundry treatment apparatus, for example, a drum dryer, in which laundry is placed in a drum, and the laundry is rotated in a rotation process of the drum, and is contacted with flowing high-temperature air, and the high-temperature air takes away moisture of the laundry (the moisture is evaporated and taken away), so that the laundry is dried rapidly.
In the embodiment of the present utility model, as shown in fig. 1 to 4, fig. 1 is a schematic cross-sectional view of an embodiment of a drum assembly of the present utility model; FIG. 2 is an enlarged view of a portion of FIG. 1 at A; FIG. 3 is a cutaway exploded view of one embodiment of a roller assembly according to the present utility model; fig. 4 is a cross-sectional orthographic view of an embodiment of a roller assembly according to the present utility model.
The roller assembly includes: the drum 10, the barrel bottom of the drum 10 is provided with an air inlet nozzle 20, the opening of the air inlet nozzle 20 faces the rotation axis of the drum 10, and the opening direction of the air inlet nozzle 20 and the rotation axis of the drum 10 form an included angle; the sealing member 30 is mounted on the outer side of the bottom of the drum 10, the sealing member 30 comprises a sealing plate 31 and a sealing edge 32, the sealing plate 31 is connected to the bottom of the drum 10, and the sealing plate 31 is provided with a through-air hole 311 corresponding to the air inlet nozzle 20; the sealing edge 32 is in a conical cylindrical shape, and one end of the sealing edge 32 along the rotation axis of the drum 10 is connected to the periphery of the sealing plate 31, and the other end is used for sealing connection of the air duct component.
In this embodiment, the bottom of the drum 10 is provided with a mounting opening, the air inlet 20 is mounted at the mounting opening, and external air flow can enter the drum 10 through the opening of the air inlet 20. The air inlet 20 is located at the circumferential side of the rotation axis of the drum 10, so that the opening of the air inlet 20 can be directed to the rotation axis of the drum 10 and the opening direction can form an included angle with the rotation axis of the drum 10. The opening direction of the air inlet nozzle 20 forms an included angle with the rotation axis of the drum 10 of more than 0 DEG and less than 90 deg.
The central portion of the drum 10, that is, a portion near the rotation axis, has less variation in position when the drum 10 rotates, and it is difficult for laundry located at the central portion to contact more air flow by changing the position. The opening of the air inlet 20 is directed to the rotation axis of the drum 10, that is, the center of the drum 10, so that the air force entering the drum 10 is firstly blown to the laundry at the center of the drum 10, so that the laundry at the center of the drum 10 can be more fully contacted with the hot air flow, and thus dried more quickly, so that the drying speed of the laundry at the center and the periphery of the drum 10 is more uniform, and the overall drying effect of the laundry in the drum 10 is more uniform.
As can be seen from the operating characteristics of the laundry treatment apparatus, the drum 10 is required to both rotate relative to and communicate with the air duct member to effect air intake. The roller 10 can be matched and communicated with the air duct component through the bottom, and the bottom of the roller 10 is matched with the air duct component through a sealing ring, so that air flow loss is reduced, and drying efficiency is improved.
The roller assembly in this embodiment is in rotational engagement with the air duct member by a seal 30. Wherein, the sealing plate 31 is connected to the outside of the bottom of the drum 10 to achieve a fixed connection of the sealing member 30 with the drum 10. The air through holes 311 on the sealing plate 31 correspond to the air inlet nozzles 20, so that air flow can smoothly pass through the sealing plate 31 and then be blown into the roller 10 from the air inlet nozzles 20.
The sealing edge 32 is used for sealing with the air duct component and is in rotatable fit, and a sealing ring is arranged between the sealing edge 32 and the air duct component. The sealing edge 32 is in a cone-shaped arrangement with one end flaring and the other end necking, wherein the sealing edge 32 can be a flaring end connected with the sealing plate 31 or a necking end connected with the sealing plate 31, and the sealing edge is not limited herein, and only needs to meet the condition that the shape of the sealing edge 32 on the shaft section of the roller 10 forms an included angle with the rotation axis of the roller 10. The sealing edge 32 is in a cone shape, so that the matching area with the air duct component can be increased, and the matching area with the sealing ring is increased, and the communication tightness between the air duct component and the roller 10 can be improved, thereby reducing the loss of air flow and improving the drying efficiency.
The sealing member 30 is separately formed and then connected to the bottom of the drum 10, so that the assembling process of the drum 10 and the sealing member 30 can be simplified, and the assembling efficiency can be improved.
Illustratively, the radial dimension of the sealing edge 32 increases from the end close to the bottom of the drum 10 to the end far away from the bottom of the drum 10, that is, the necking end of the sealing edge 32 is connected to the sealing plate 31, and the flaring end is used for matching with the air duct component, so that the sealing edge 32 and the air duct component are conveniently assembled, and the assembly difficulty is further reduced.
Specifically, the included angle a between the opening direction of the air inlet nozzle 20 and the rotation axis of the drum 10 is set to 10 ° to 80 °, for example, 10 °, 20 °, 30 °, 40 °, 50 °, 55 °, 60 °, 65 ° or 70 °, 75 ° or 80 °. Thus, the air flow of the air intake can be blown to the middle part of the drum 10 in the axial direction and then spread from the middle part towards the drum opening and the drum bottom, so that the drying effect on the clothes at each part in the drum 10 is more uniform.
The number of the air inlet nozzles 20 may be one or two or more. As shown in fig. 1 and 3, the number of the air inlet nozzles 20 is at least two, and the at least two air inlet nozzles 20 are spaced apart along the circumferential direction of the drum 10. The number of the air inlet nozzles 20 is set to be plural, and the air inlet position of the drum 10 can be increased to further improve the drying efficiency of the laundry. In addition, the air flow blown into the drum 10 from each air inlet 20 is blown to the central portion of the drum 10, so that a plurality of air flows are converged at the central portion of the drum 10 to form a swirl flow, thereby improving the effect on the laundry.
