Detailed Description

In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 2 and 3, fig. 2 is a schematic structural diagram of an embodiment of a washing and drying all-in-one machine provided by the present invention; fig. 3 is a partially enlarged view of a portion a in fig. 2.

The washing and drying integrated machine has a drying function, and can quickly dry washed clothes so as to adapt to the acceleration of the life rhythm of people or the humid climate in the south.

In this embodiment, the drum of the washing and drying integrated machine comprises an inner drum 11 and an outer drum 12 with one open end, wherein the outer drum 12 is fixed, and the inner drum 11 can rotate relative to the outer drum 12. A certain gap is provided between the inner cylinder 11 and the outer cylinder 12.

The washing and drying integrated machine further comprises a choke ring 20, and the choke ring 20 is arranged between the inner cylinder 11 and the outer cylinder 12 to at least partially block a gap between the inner cylinder 11 and the outer cylinder 12.

As above, when the hot air of the washing and drying integrated machine enters the inner barrel 11, if part of the hot air enters the gap between the inner barrel 11 and the outer barrel 12, the part of the hot air will not be lost completely under the blocking of the choke ring 20, and finally will still flow into the inner barrel 11.

In a specific embodiment, the choke coil 20 is fixedly mounted on the outer wall of the inner tube 11 at the inner periphery thereof and is overlapped with the inner wall of the outer tube 12 at the outer periphery thereof, or the choke coil 20 is fixedly mounted on the inner wall of the outer tube 12 at the outer periphery thereof and is overlapped with the outer wall of the inner tube 11 at the inner periphery thereof.

That is, one of the inner and outer circumferences of the choke ring 20 is fixed to one of the inner and

outer cylinders

11 and 12 and the other overlaps the other of the inner and

outer cylinders

11 and 12, so that the choke ring 20 is not damaged when the inner cylinder 11 rotates, so that the choke ring 20 can either rotate together with the inner cylinder 11 or block the rotation of the inner cylinder 11.

More specifically, the choke ring 20 has an inner periphery in contact with the outer wall of the inner cylinder 11 and an outer periphery in contact with the inner wall of the outer cylinder 12.

Thus, the choke ring 20 can completely block the gap between the inner cylinder 11 and the outer cylinder 12, so that even if hot air enters between the inner cylinder 11 and the outer cylinder 12, the hot air can be blocked and completely flows into the inner cylinder 11 to participate in the clothes drying process.

In addition to the above, the choke ring 20 may be provided as follows: one of the inner and outer peripheries of the choke ring 20 is fixed to one of the inner and

outer cylinders

11 and 12, and the other is disposed in close proximity to the other of the inner and

outer cylinders

11 and 12.

Thus, a small gap is left between the non-fixed end of the choke ring 20 and the inner cylinder 11 or the outer cylinder 12, which can basically achieve the function of plugging the gap between the inner cylinder and the outer cylinder, and meanwhile, the inner cylinder 11 is not prevented from rotating relative to the outer cylinder 12 at all.

In comparison, the inner and outer circumferences of the choke ring 20 are in contact with the inner and

outer cylinders

11 and 12, respectively, so that the gap between the inner and outer cylinders can be completely sealed, and the loss of hot air by-pass can be completely avoided. In practical application, a specific setting mode can be selected according to factors such as installation cost and the like.

In a specific scheme, the choke ring 20 is preferably made of a flexible material, such as rubber, and the inner periphery or the outer periphery of the choke ring 20 is overlapped with the inner cylinder 11 or the outer cylinder 12, so that when the inner cylinder 11 rotates, collision or friction is inevitable, and the choke ring 20 made of the flexible material is selected, so that on one hand, abrasion can be relieved, and on the other hand, noise generated during friction can be reduced.

In a specific scheme, the fixed installation mode of the choke ring 20 is bonding or screw connection, that is, when the inner circumference of the choke ring 20 is fixedly installed with the inner cylinder 11, the bonding or screw connection mode can be adopted, and when the outer circumference of the choke ring 20 is fixedly installed with the outer cylinder 12, the bonding or screw connection mode can also be adopted, so that the device is simple and reliable.

In addition, when the inner periphery of the choke ring 20 is fixedly installed with the inner cylinder 11, the choke ring can be fixed with the inner cylinder 11 by utilizing the elasticity of the choke ring, for example, the choke ring 20 is made of rubber made of flexible materials, has certain elasticity, can be directly sleeved on the inner cylinder 11 by virtue of the elasticity of the choke ring to realize fixation, and is more convenient and faster compared with bonding or screw connection; meanwhile, the periphery of the choke ring 20 can be attached to the outer cylinder 12 by elasticity to block the gap between the inner cylinder 11 and the outer cylinder 12.

In the specific scheme, the cross section of the choke ring 20 is arc-shaped, and the lap joint end of the choke ring is tangent to the cylinder wall; it can be understood that if the inner periphery of the choke ring 20 is fixedly connected with the inner cylinder 11, the outer periphery is a lap joint end and is in tangential lap joint with the outer cylinder 12; if the periphery of the choke ring 20 is fixed with the outer cylinder 12, the inner periphery is a lap joint end and is in tangential lap joint with the inner cylinder 11; this is advantageous for increasing the contact surface between the choke ring 20 and the inner cylinder 11 or the outer cylinder 12, and for closing the gap between the inner cylinder 11 and the outer cylinder 12. Wherein, the outer convex surface of the choke ring 20 can be towards the front end of the roller or towards the rear end of the roller.

Please refer to fig. 4 to fig. 6; FIG. 4 is a schematic structural diagram of a drum of the washing and drying integrated machine with hot air entering the drum in the specific embodiment; FIG. 5 is a schematic view showing the flow of hot air from the inlet drum to the outlet drum in the exemplary embodiment; fig. 6 is a partially enlarged view of a portion B in fig. 5.

In this embodiment, the air inlet of the hot air in the drying process is arranged above the door body 13, specifically, obliquely above, and is shown as the upper left of the door body 13 in fig. 4, that is, the hot air heated by the heating system of the washing and drying all-in-one machine flows into the drum from the upper left of the door body 13.

Referring to fig. 5, the hot air flows in from the upper left of the door 13, enters the inner cylinder 11, and then flows out from the rear end (right side in the figure) of the drum, and if some of the hot air enters the gap between the inner cylinder 11 and the outer cylinder 12 during the hot air flowing process, the hot air is blocked by the choke ring 20 to flow back to the inner cylinder 11, and finally flows out from the rear end of the drum. Therefore, hot air of the system can enter the inner barrel 11 to participate in drying, bypass loss is avoided, energy consumption is reduced, and drying efficiency is improved.

The hollow arrows in fig. 4 and 5 show the flow path of the hot air.

Wherein, the door body 13 is provided with a curved surface structure 131 so as to guide the hot air passing through the air inlet to the inner cylinder 11. Therefore, after hot air enters from the air inlet, the hot air is guided into the inner barrel 11, and the wind resistance of the hot air entering the inner barrel 11 is reduced.

In a specific scheme, the door body 13 is a symmetrical structure, and the air inlet is located on a symmetrical axis L of the door body 13. In the orientation shown in fig. 4, the air inlet is located at the upper left of the door body 13, and the symmetry axis L of the door body 13 inclines to the left; certainly, during actual setting, the air inlet can also be positioned at the upper right of the door body 13, and at this time, the symmetric axis L of the door body 13 is inclined to the right; of course, the air inlet may be disposed right above the door 13, and at this time, the symmetry axis L of the door 13 is parallel to the vertical direction.

In a specific embodiment, the curved surface structure 131 of the door 13 is in the following form: approximately along the symmetry axis of the door 13, the inner wall surface of the door 13 from the near side to the far side from the air inlet gradually approaches the inner cylinder 11, as can be understood with reference to fig. 5. It is to be noted that, for the sake of understanding, the axis of symmetry of the door body 13 shown in fig. 5 is parallel to the vertical direction.

In practice, the air inlet on the upper left of the door 13 is usually arranged on the door seal between the inner cylinder 11 and the outer cylinder 12, in this scheme, the air inlet can also be arranged on the outer cylinder 12, and the arrangement of the choke ring 20 avoids the bypass of hot air, so that the arrangement of the air inlet on the outer cylinder 12 does not cause the loss of hot air.

In a specific embodiment, the choke ring 20 may be provided between the circumferential walls of the inner tube 11 and the outer tube 12, as shown in fig. 2 and 3, and of course, the choke ring 20 may be provided between the bottom walls of the inner tube 11 and the outer tube 12 as long as the gap between the inner tube 11 and the outer tube 12 can be closed, and the hot air bypass loss can be avoided.

In contrast, if the choke ring 20 is disposed between the circumferential walls of the inner and

outer cylinders

11 and 12, the choke ring 20 is located at a short distance from the air inlet of the drum, and if hot air enters between the inner and

outer cylinders

11 and 12, the distance that the choke ring 20 blocks the flow back to the inner cylinder 11 is relatively short, which can reduce the loss along the way, and therefore, in practice, it is preferable to dispose the choke ring 20 between the circumferential walls of the inner and

outer cylinders

11 and 12.

In a specific embodiment, a plurality of choke rings 20 are disposed between the inner tube 11 and the outer tube 12, so that the effect of the choke rings 20 in preventing the bypass of the hot air can be improved.

During specific setting, in two adjacent choke rings 20, the inner periphery of one is fixedly mounted with the inner cylinder 11, the outer periphery is lapped on the outer cylinder 12, the outer periphery of the other is fixedly mounted with the outer cylinder 12, and the inner periphery is lapped on the inner cylinder 11, so that the fixed ends of the two adjacent choke rings 20, the inner cylinder 11 and the outer cylinder 12 are designed in a staggered manner, and the plugging effect of the choke rings 20 on the gap between the inner cylinder 11 and the outer cylinder 12 can be enhanced.

Certainly, in the specific arrangement, the orientations of the outer convex surfaces of the choke rings 20 are different from each other, which is more beneficial to blocking the bypass of the hot air.

Specifically, referring to fig. 7, fig. 7 shows four specific arrangements of the choke ring between the cylindrical peripheral walls of the inner and

outer cylinders

11 and 12.

As shown in fig. 7, the choke ring 20a has an inner periphery fixedly attached to the outer wall of the inner cylinder 11 and an outer periphery overlapping the inner wall of the outer cylinder 12, and an outer peripheral surface of the choke ring 20a faces the rear end of the drum, i.e., the right side in the figure.

The outer circumference of the choke ring 20b is fixedly mounted on the inner wall of the outer cylinder 12, the inner circumference is lapped on the outer wall of the inner cylinder 11, and the outer convex surface of the choke ring 20b faces the front end of the roller, namely the left side in the figure.

The outer periphery of the choke ring 20c is fixedly mounted with the inner wall of the outer cylinder 12, the inner periphery is lapped on the outer wall of the inner cylinder 11, and the outer convex surface of the choke ring 20c faces the rear end of the roller.

The inner circumference of the choke ring 20d is fixedly mounted with the outer wall of the inner cylinder 11, the outer circumference is lapped on the inner wall of the outer cylinder 12, and the outer convex surface of the choke ring 20d faces the front end of the roller.
