When the drying equipment is drying clothes, the first drying air duct 2 and the second drying air duct 3 can blow hot air into the drying drum 1 at the same time, which increases the amount of hot air and can make the water in the clothes evaporate quickly into water vapor, thereby improving the drying efficiency of the drying equipment.

[0040] It should be noted that the present invention does not limit the setting positions of the first drying duct 2 and the second drying duct 3. For example, those skilled in the art may set the first drying duct 2 and the second drying duct 3 simultaneously or separately at the top end, bottom end, left end or right end of the drying drum 1, etc. Such adjustments and changes to the specific setting positions of the first drying duct 2 and the second drying duct 3 do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

For example, a person skilled in the art may set the air outlets and return air outlets of the first drying air duct 2 and the second drying air duct 3 simultaneously or separately at the top end, bottom end, left end or right end of the drying cylinder 1, etc. Such adjustments and changes to the specific setting positions of the air outlets and return air outlets of the first drying air duct 2 and the second drying air duct 3 do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0042] It should be further explained that the present invention does not limit the type of electric heating components. For example, a person skilled in the art may set the electric heating components as heating wires or heating plates, etc. Such adjustments and changes to the specific types of electric heating components do not deviate from the principles and scope of the present invention and should be limited within the scope of protection of the present invention.

[0043] Preferably, if Figure 2 As shown, the rear wall of the drying drum 1 of the present invention is provided with a first air inlet and a second air inlet, and the air outlet of the first drying air duct 2 and the air outlet of the second drying air duct 3 are respectively connected to the first air inlet and the second air inlet.

[0044] For example, Figure 2 As shown, the utility model provides a first air inlet and a second air inlet on the rear wall of the drying drum 1, the air outlet of the first drying air duct 2 is connected with the first air inlet, and the air outlet of the second drying air duct 3 is connected with the second air inlet. By arranging the first air inlet and the second air inlet on the rear wall of the drying drum 1 at the same time, the hot air in the first drying air duct 2 and the second drying air duct 3 do not affect each other when blowing into the drying drum 1, thereby improving the air outlet efficiency.

[0045] Preferably, if Figure 1 As shown, the front end of the side wall of the drying cylinder 1 of the present invention is provided with a first exhaust port and a second exhaust port, and the return air port of the first drying air duct 2 and the return air port of the second drying air duct 3 are connected to the first exhaust port and the second exhaust port respectively.

[0046] For example, Figure 1As shown, the front end of the side wall of the drying cylinder 1 of the utility model is provided with a first exhaust port and a second exhaust port, the return air port of the first drying air duct 2 is connected with the first exhaust port, and the return air port of the second drying air duct 3 is connected with the second exhaust port. By arranging the first exhaust port and the second exhaust port at the front end of the side wall of the drying cylinder 1 at the same time, the return air of the first drying air duct 2 and the second drying air duct do not affect each other, thereby improving the return air efficiency.

[0047] Preferably, if Figure 1 and Figure 2 As shown, the first drying air duct 2 of the utility model is located below the drying drum 1 , and the second drying air duct 3 is located above the drying drum 1 .

[0048] For example, Figure 1 and Figure 2 As shown, the first drying air duct 2 of the utility model is installed at the bottom of the drying drum 1 along the front-to-back direction, and the second drying air duct 3 is installed at the top of the drying drum 1 along the front-to-back direction. This arrangement has a more reasonable layout and makes the heat pump system more efficient.

[0049] Preferably, the electric heating component of the present invention is arranged close to the air outlet of the second drying air duct 3 .

[0050] That is to say, the wind in the second drying air duct 3 is heated by the electric heating component and then directly sent into the drying drum 1 through the air outlet, so that the hot air temperature is higher and the drying efficiency is improved.

[0051] Of course, the electric heating component of the utility model can also be arranged close to the return air outlet of the second drying air duct 3. In this way, the air in the second drying air duct 3 is heated at the return air outlet and then fully mixed in the second drying air duct 3 before entering the drying drum 1, thereby making the temperature of the hot air more uniform and the drying effect better. Technical personnel in this field can reasonably set the position of the electric heating component according to actual usage requirements.

[0052] Preferably, if Figure 3 As shown, the inner side wall of the drying drum 1 of the present invention is provided with lifting ribs 11 extending along a first direction, and the first direction is the axial direction of the drying drum 1 .

[0053] For example, Figure 3 As shown, the inner wall of the drying drum 1 of the utility model is provided with lifting ribs 11 in the front-to-back direction. As the drying drum 1 rotates, the lifting ribs 11 can lift the clothes to a certain height and shake the clothes, and the clothes then fall from the lifting ribs 11 to the bottom of the drying drum 1. In this repeated lifting process, the contact area between the clothes and the hot air can be increased, thereby improving the drying efficiency.

[0054] It should be noted that the present invention does not limit the number and structural form of the lifting ribs 11. For example, a person skilled in the art may set the lifting ribs 11 to be multiple and spaced apart along the circumference of the drying drum 1, or may set the lifting ribs 11 to be fan-shaped or hump-shaped, etc. Such adjustments and changes to the specific number and structural form of the lifting ribs 11 do not deviate from the principle and scope of the present invention, and shall be limited within the protection scope of the present invention.

[0055] Preferably, if Figure 3 As shown, the utility model has a plurality of lifting ribs 11 , and the plurality of lifting ribs 11 are distributed at intervals along the circumference of the drying drum 1 .

[0056] For example, Figure 3 As shown, the number of the lifting ribs 11 of the present invention is two, and the two lifting ribs 11 are symmetrically arranged on the inner wall of the drying cylinder 1.

[0057] Of course, the lifting ribs 11 of the present invention can also be set to three or four, etc., which are distributed at intervals. Those skilled in the art can set them according to specific usage requirements.

[0058] Preferably, if Figure 3 As shown, the width of the lifting rib 11 of the present invention along the second direction gradually decreases from the end of the lifting rib 11 toward the middle of the lifting rib 11 , and the second direction is the radial direction of the drying drum 1 .

[0059] For example, Figure 3 As shown, the lifting rib 11 of the utility model is in the shape of a triangle, the bottom end of the triangle is installed on the inner wall of the drying drum 1, the pointed top of the triangle extends toward the inside of the drying drum 1, and the width of the triangle along the left and right directions gradually decreases from the front and rear ends toward the middle, that is, the two ends of the lifting rib 11 are wide and the middle is narrow. Such a structural design allows the clothes to gather to the middle position of the drying drum 1 when being lifted by the lifting rib 11, thereby making the clothes more evenly distributed in the drying drum 1, further increasing the contact area between the clothes and the hot air, and improving the drying efficiency.

[0060] It should be noted that the connection between the lifting rib 11 and the drying drum 1 is the bottom wall, the top of the lifting rib 11 is the top wall, the front and rear sides of the lifting rib 11 are the front wall and the rear wall respectively, and the other two sides are the left wall and the right wall, wherein the left wall and the right wall are the lifting surfaces of the lifting rib 11 for lifting clothes, that is, the width of the left wall and the right wall is a structural form that is wide at both ends and narrow in the middle.

[0061] In practical applications, the wall surfaces of the left wall and the right wall can be flat surfaces or inclined surfaces, such as Figure 3As shown in the figure, the right wall of the lifting rib 11 located on the right side of the drying cylinder 1 (the right wall is located on the upper side of the lifting rib 11 as seen in the figure) is arranged to be inclined downward in the direction from back to front, that is, the rear end of the wall surface of the right wall is high and the front end is low. Similarly, the wall surface of the left wall is also arranged to be inclined downward in the direction from back to front, that is, the rear end of the wall surface of the left wall is high and the front end is low. The lifting rib 11 located on the left side of the drying cylinder 1 and the lifting rib 11 located on the right side of the drying cylinder 1 are arranged symmetrically relative to the center of the rotating shaft of the drying cylinder 1, that is, the left wall and the right wall of the lifting rib 11 located on the left side of the drying cylinder 1 are symmetrically arranged relative to the center of the rotating shaft of the drying cylinder 1. The wall surface of the wall is arranged upwardly and inclined in the direction from back to front, that is, the rear end of the wall surface of the left wall is low and the front end is high. Through such an arrangement, when the drying drum 1 rotates clockwise, the clothes on the lifting ribs 11 gather toward the middle and can also move toward the rear end of the drying drum 1. When the drying drum 1 rotates counterclockwise, the clothes on the lifting ribs 11 gather toward the middle and can also move toward the front end of the drying drum 1, thereby making the shaking effect of the clothes more significant, further increasing the contact area between the clothes and the hot air, and improving the drying efficiency.

[0062] Preferably, if Figure 3 As shown, a disturbance structure 12 is provided on the rear inner wall of the drying drum 1 of the present invention.

[0063] For example, Figure 3 As shown, a disturbance structure 12 is provided in the middle position of the rear inner wall of the drying drum 1 of the utility model. The disturbance structure 12 is hemispherical. By providing the disturbance structure 12, when the clothes are gathered at the rear end of the drying drum 1, the disturbance structure 12 can shake the clothes and push them to the middle position of the drying drum 1, thereby preventing the clothes from being tangled.

[0064] Preferably, a disturbance structure 12 is provided on the inner wall of the window 4 of the drying device.

[0065] Exemplarily, a disturbance structure 12 is provided in the middle position of the window 4 of the drying drum 1 of the utility model, and the disturbance structure 12 is hemispherical. By providing the disturbance structure 12, when the clothes are gathered at the window 4 of the drying drum 1, the disturbance structure 12 can shake the clothes and push them to the middle position of the drying drum 1, thereby preventing the clothes from being tangled.

[0066] Preferably, if Figure 3 As shown, a plurality of through holes 121 are provided on the disturbance structure 12 of the present invention.

[0067] For example, Figure 3As shown, a plurality of through holes 121 are arranged at intervals on the disturbance structure 12 of the utility model. By providing a plurality of through holes 121, the air permeability of the disturbance structure 12 is increased, so that when the disturbance structure 12 pushes and shakes the clothes, the contact area between the hot air and the clothes can be increased, thereby improving the drying efficiency.
