[0002] With the improvement of people's living standards, clothes dryers have gradually become one of the indispensable household appliances in people's daily lives.

[0003] Most of the existing clothes dryers dry clothes by setting a heat pump system in the air duct. The hot air circulates in the drying cylinder and the air duct to take out the humid air in the drying cylinder, then condenses the water vapor in the humid air through the condenser of the heat pump system, heats the air through the evaporator, and blows the hot air into the drying cylinder through the blower, so as to achieve the effect of drying clothes. During the drying process, the blower blows hot air into the drying cylinder through the air supply duct. Due to the relatively fast air flow velocity and the small air inlet of the drying cylinder, the hot air is unevenly distributed in the drying cylinder, resulting in a reduction in the contact area between the hot air and the clothes, and thus reducing the drying efficiency of the clothes dryer.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Utility Model

By arranging the supply air duct 4 as the first supply air duct 41 and the second supply air duct 42 in parallel and respectively communicating the first supply air duct 41 and the second supply air duct 42 with the first air inlet 11 and the second air inlet 12, the area of the supply air duct 4 is increased, the number of air inlets is increased, so that the air flow can enter the drying cylinder 1 evenly through the first air inlet 11 and the second air inlet 12, thereby increasing the contact area between the air flow and the clothes and improving the drying efficiency of the dryer.

[0044] Preferably, as Figure 1 shown, the first supply air duct 41 of the dryer of the present utility model extends along the circumferential direction of the drying cylinder 1, the number of the first air inlets 11 is multiple, and the multiple first air inlets 11 are arranged at intervals along the flowing direction of the air flow in the first supply air duct 41.

[0045] Exemplarily, as Figure 1As shown, the first air supply duct 41 of the present utility model is arranged on the rear wall of the drying cylinder 1 and extends along the circumferential direction of the rear wall. The number of the first air inlets 11 is three, and the three first air inlets 11 are spaced apart along the flowing direction of the air flow in the first air supply duct 41 (counterclockwise as viewed from Figure 1 inside). Such an arrangement enables the air flow in the first air supply duct 41 to enter the drying cylinder 1 evenly through the three first air inlets 11.

[0046] It should be noted that the present utility model does not limit the number of the first air inlets 11. For example, those skilled in the art can also set the number of the first air inlets 11 to four, five, etc. Such adjustments and changes to the specific number of the first air inlets 11 do not deviate from the principle and scope of the present utility model and should all be limited within the protection scope of the present utility model.

[0047] Preferably, as Figure 1 shown, a first wind-blocking member 61 is provided between two adjacent first air inlets 11 in the first air supply duct 41 of the dryer of the present utility model. The first wind-blocking member 61 is used to block part of the air flow, and the blocked air flow enters the drying cylinder 1 through the first air inlet 11 upstream of the first wind-blocking member 61.

[0048] Exemplarily, as Figure 1 shown, a first wind-blocking member 61 is provided between every two adjacent first air inlets 11 of the present utility model. By providing the first wind-blocking plate 61, the blocked air flow can enter the drying cylinder 1 through the first air inlet 11 upstream of the first wind-blocking member 61, so that the air flow in the first air supply duct 41 can be evenly dispersed into multiple first air inlets 11, and thus the air flow enters the drying cylinder 1 evenly.

[0049] It should be noted that the present utility model does not limit the number of the first wind-blocking members 61. For example, those skilled in the art can set one, two or more first wind-blocking members 61 between two adjacent first air inlets 11, etc. Such adjustments and changes to the specific number of the first wind-blocking members 61 do not deviate from the principle and scope of the present utility model and should all be limited within the protection scope of the present utility model.

[0050] Preferably, as Figure 1 shown, a first wind-blocking member 61 is provided between two adjacent first air inlets 11 of the dryer of the present utility model. At least two first wind-blocking members 61 are provided in the first air supply duct 41, and the height of the first wind-blocking member 61 increases along the flowing direction of the air flow.

[0051] Exemplarily, as Figure 1As shown in the figure, the number of the first air inlets 11 of the present utility model is three. A first wind-blocking member 61 is provided between two adjacent first air inlets 11. That is to say, two first wind-blocking members 61 are provided. The height of the first wind-blocking member 61 increases along the flowing direction of the air flow. That is to say, the first wind-blocking members 61 are arranged in a stepped manner along the flowing direction of the air flow. Such a setting can distribute the air flow more evenly into the two first air inlets 11, so that the air flow entering the drying cylinder 1 is more uniform.

[0052] Preferably, as Figure 1 shown, the number of the second air inlets 12 of the dryer of the present utility model is at least two and they are arranged at intervals along the flowing direction of the air flow in the second air supply duct 42.

The two second air inlets 12 are arranged at intervals along the flowing direction of the air flow in the second air supply duct 42 (viewed as counterclockwise from Figure 1 inside). Such a setting enables the air flow in the second air supply duct 42 to enter the drying cylinder 1 evenly through the two second air inlets 12.

[0054] Preferably, as Figure 1 shown, the second air supply duct 42 of the dryer of the present utility model extends along the circumferential direction of the drying cylinder 1. A second wind-blocking member 62 is arranged at the end of the second air supply duct 42. The second wind-blocking member 62 is used to block the air flow to prevent the air flow from colliding with the newly entered air flow.

[0055] Exemplarily, as Figure 1 shown, the second air supply duct 42 of the present utility model is arranged on the rear wall of the drying cylinder 1 and extends along the circumferential direction of the rear wall. The second air supply duct 42 is located inside the first air supply duct 41. A second wind-blocking member 62 is arranged at the end of the second air supply duct 42. By arranging the second wind-blocking member 62, when the air flow flows in the second air supply duct 42 for one week, the second wind-blocking member 62 can block the air flow, avoiding the collision and conflict between the air flow and the air flow newly blown by the fan 5, thus affecting the air supply efficiency, and can also make the air flow enter the drying cylinder 1 more evenly through the second air inlets 12.

[0056] Preferably, as Figure 3 shown, lifting ribs 13 extending in the first direction are arranged on the inner side wall of the drying cylinder 1 of the present utility model. The first direction is the axial direction of the drying cylinder 1.

[0057] Exemplarily, as Figure 3As shown, lifting ribs 13 are provided on the inner sidewall of the drying cylinder 1 of the present utility model in the front-back direction. During the rotation of the drying cylinder 1, the lifting ribs 13 can lift the clothes to a certain height and shake them loose, and then the clothes fall from the lifting ribs 13 to the bottom of the drying cylinder 1. During this repeated lifting process, the contact area between the clothes and the hot air can be increased, improving the drying efficiency.

[0058] It should be noted that the present utility model does not limit the number and structural form of the lifting ribs 13. For example, those skilled in the art can set the lifting ribs 13 as multiple ones spaced circumferentially along the drying cylinder 1, or can also set the lifting ribs 13 in the shape of fan blades or humps, etc. Such adjustments and changes to the specific number and structural form of the lifting ribs 13 do not deviate from the principle and scope of the present utility model and should all be limited within the protection scope of the present utility model.

[0059] Preferably, as Figure 3 shown, the number of the lifting ribs 13 of the present utility model is multiple, and the multiple lifting ribs 13 are spaced circumferentially along the drying cylinder 1.

[0060] Exemplarily, as Figure 3 shown, the number of the lifting ribs 13 of the present utility model is two, and the two lifting ribs 13 are symmetrically arranged on the inner wall of the drying cylinder 1.

[0061] Of course, the lifting ribs 13 of the present utility model can also be set as three or four spaced apart, etc., and those skilled in the art can set them according to specific usage requirements.

[0062] Preferably, as Figure 3 shown, the width of the lifting rib 13 of the present utility model in the second direction gradually increases from the end of the lifting rib 13 towards the middle of the lifting rib 13, and the second direction is the radial direction of the drying cylinder 1.

[0063] Exemplarily, as Figure 3 shown, the lifting rib 13 of the present utility model is in the shape of a triangular prism.

The width of the triangular prism in the left-right direction gradually increases from the front and back ends towards the middle. That is to say, the two ends of the lifting rib 13 are narrow and the middle is wide. Such a structural design enables the clothes to gather towards the front and back ends of the drying cylinder 1 when being lifted along with the lifting rib 13, so that the clothes are more evenly distributed in the drying cylinder 1, further increasing the contact area between the clothes and the hot air and improving the drying efficiency.

[0064] Preferably, as Figure 2 shown, a first air guiding plate 71 is provided on the sidewall at the connection of the return air duct 2 of the clothes dryer of the present utility model with the air outlet, and the first air guiding plate 71 extends along the flowing direction of the air flow.

[0065] Exemplarily, as Figure 2 shown, the connection of the return air duct 2 of the present utility model with the air outlet is arc-shaped. When the air flow passes through, eddy currents will be generated, thereby reducing the air flow velocity, which in turn affects the air supply efficiency of the return air duct 2. By providing the first air guide plate 71, the air flow can be guided to avoid the generation of eddy currents.

[0066] It should be noted that the present utility model does not limit the number of the first air guide plates 71. For example, those skilled in the art can set the first air guide plates 71 to three, four, etc. Such adjustments and changes to the specific number of the first air guide plates 71 do not deviate from the principle and scope of the present utility model and should all be limited within the protection scope of the present utility model.

[0068] Exemplarily, as Figure 1 shown, the position of the air supply duct 4 of the present utility model near the air outlet of the fan 5 is arc-shaped.

By providing the second air guide plate 72, the air flow can be guided to avoid the generation of eddy currents.

[0069] It should be noted that the present utility model does not limit the number of the second air guide plates 72. For example, those skilled in the art can set the second air guide plates 72 to three, four, etc. Such adjustments and changes to the specific number of the second air guide plates 72 do not deviate from the principle and scope of the present utility model and should all be limited within the protection scope of the present utility model.

By providing the perturbation structure 14, when the clothes are gathered at the rear end of the drying cylinder 1, the perturbation structure 14 can shake the clothes loose and push them towards the middle position of the drying cylinder 1, preventing the clothes from knotting.

[0072] Preferably, as Figure 2 shown, the number of the first air guide plates 71 of the dryer of the present utility model is multiple, and the multiple first air guide plates 71 are distributed at intervals along the circumferential direction of the return air duct 2.

[0073] Exemplarily, as Figure 2 shown, the number of the first air guide plates 71 of the present utility model is three, and the three first air guide plates 71 are distributed at intervals along the circumferential direction of the return air duct 2.

[0074] Preferably, as Figure 1 shown, the number of the second air guide plates 72 of the clothes dryer of the present utility model is multiple, and the multiple second air guide plates 72 are distributed at intervals along the circumferential direction of the air supply duct 4.

[0077] Exemplarily, as Figure 3 shown, a plurality of through holes 141 are arranged at intervals on the disturbance structure 14 of the present utility model. By providing the plurality of through holes 141, the air permeability of the disturbance structure 14 is increased, so that when the disturbance structure 14 pushes and shakes the clothes, the contact area between the hot air and the clothes can also be increased, thereby improving the drying efficiency.
