The warm air dried by the heat pump device in the air duct passes through the rear air duct and the rolling bottom into the dryer drum. The dry warm air passes through the dryer drum and takes away the residual water on the lifted clothes, turning into humid warm air. The humid warm air passes through the air duct at the lower end of the door body and enters the chassis, where it is condensed, dried and heated by the heat pump device, thus forming a cycle to dry the clothes.

[0003] The existing clothes dryer has multiple openings at the bottom for ventilation. However, the openings at the bottom of the clothes dryer are now round. After the dry warm air enters the clothes dryer from the rear air duct, the dry warm air will blow directly toward the door. When there are a lot of clothes, the edge of the inner wall of the clothes dryer and the edge of the bottom of the clothes dryer cannot be blown by the dry warm air. The dry warm air does not contact the clothes sufficiently, and some clothes may not be dry enough, resulting in poor drying effect and long drying time, which increases the power consumption of drying and affects the user experience.

[0042] Embodiment 1

[0043] Based on this, Figure 1-Figure 8As shown, a clothes drying drum according to an embodiment of the present invention comprises:

[0044] The cylinder 1 comprises a side wall and a bottom wall, the side wall is formed with a delivery port at the front end of the cylinder, the side wall is formed with an air outlet near the delivery port, the side wall and the bottom wall surround a cylinder cavity, and the air outlet is connected to the cylinder cavity;

[0045] The bottom wall 2 is provided with an air guide structure 3, which is used to introduce the air of the drying system directly into the cylinder cavity through the bottom wall 2 and flow to the air outlet in a swirling manner.

[0046] Specifically, the dryer can be a drum, and the dryer can be cylindrical. One end of the dryer is a loading port for storing and taking out clothes 11, and the other end is the bottom wall 2 of the dryer. The dry warm air of the dryer enters the dryer from the bottom wall 2 of the dryer to dry the clothes 11 in the dryer.

[0047] The air guide structure 3 has a ventilation hole 32 and an air guide cover 31. The arc center of the ventilation hole 32 can be concentric with the bottom wall 2. The dry warm air discharged from the rear air duct 5 of the dryer can enter the drying drum through the ventilation hole 32 to dry the clothes 11 in the drying drum.

[0048] The clothes drying drum can rotate counterclockwise in the rear view. Figure 1 The arrow in the figure indicates the direction of rotation of the dryer drum.

[0049] According to the clothes drying drum of the embodiment of the present invention, an air guiding structure 3 is provided on the bottom wall 2 of the drum body 1, so that the dry warm air discharged from the rear air duct 5 of the dryer can enter the interior of the drum body 1 through the air guiding structure 3, and the dry warm air can be guided by the air guiding cover 31 and the ventilation holes 32 provided in the air guiding structure 3, so that after the dry warm air enters the drum body 1, it is not directly blown to the feeding port, but a spiral airflow is formed inside the drum body 1, so that the contact stroke of the dry warm air and the clothes 11 can be lengthened, and the dry warm air can be blown to the edges of the side walls and the bottom wall 2 of the drum body 1, and the clothes 11 at the edges of the inner side walls of the dryer and the edges of the bottom of the dryer can be dried, so that the dry warm air can be blown into the gaps between the clothes 11 more, so that the dry warm air can fully contact the clothes 11, and the clothes 11 in the drum body 1 can be evenly dried, thereby shortening the overall drying time, reducing the power consumption for drying, and improving the user experience.

[0050] In some embodiments, the plurality of air guide structures 3 form a plurality of groups with different rotational distributions, and each group has a plurality of air guide structures 3 distributed from near to far;

[0051] Multiple groups of wind guide structures are distributed in a spiral shape.

[0052] Specifically, the multiple groups of air guide structures distributed in a spiral shape can enable the dry warm air to better form a spiral airflow when entering the interior of the barrel 1, thereby drying the clothes 11 at different positions.

[0053] In some embodiments, each air-guiding structure 3 includes a ventilation hole 32 and an air-guiding cover 31 that penetrate the bottom wall 2 along the thickness of the bottom wall 2, and the ventilation hole 32 and the air-guiding cover 31 extend from near to far along the rotation direction of the air-guiding structure 3 group in which they are located, wherein the air-guiding cover 31 is arranged at the far end of the ventilation hole 32, and the air-guiding cover 31 protrudes toward the outside of the bottom wall.

[0054] Specifically, the air guide hood 31 can be a shell that protrudes from the bottom wall 2 toward the outside of the drying drum, and the inner side of the air guide hood 31 can form an inclined air duct, and the air outlet and air inlet of the air guide hood 31 are the air outlet and air inlet of the air duct, and the air inlet of the air guide hood 31 has the same rotation direction as the drum body 1, so that more dry warm air can be guided into the inclined air duct while the drum body 1 rotates. The air outlet of the air guide hood 31 is connected with the ventilation holes 32, so that after the dry warm air enters the inclined air duct, it can enter the interior of the drum body 1 through the ventilation holes 32, and with the continuous rotation of the drum body 1, it can enter the drum body 1 to form a spiral airflow, so that the dry warm air can be dispersed to the surroundings of the drum body 1 under the action of the air guide structure 3, and the clothes 11 at the edge of the inner wall of the drum body 1 and the bottom edge of the drum body 1 can be dried, thereby ensuring the drying effect of the dry warm air on the clothes 11 at various locations in the drum body 1.

[0055] In some embodiments, the air guide structure further includes an air guide groove, which extends in the same direction as the ventilation hole 32 and the air guide cover 31 , and is disposed at the proximal end of the ventilation hole 32 , and is concave toward the inner side of the bottom wall.

[0056] Specifically, the air guide groove recessed toward the inner side of the cylinder can enable the air guide structure to better guide the air, thereby increasing the airflow intensity of the dry warm air entering the cylinder.

[0057] In some embodiments, the bottom wall 2 is provided with a plurality of wind guide structures 3, the wind guide structure 3 has ventilation holes 32 and wind guide covers 31, the cross section of the ventilation holes 32 on the plane of the bottom wall 2 is arc-shaped, the wind guide covers 31 have an air inlet and an air outlet, the air inlet has the same rotation direction as the cylinder 1 and protrudes toward the outside of the bottom wall 2, the air outlet is connected with the ventilation holes 32, the ventilation holes 32 have a first end and a second end in sequence along the rotation direction of the cylinder 1, wherein the first end is the distal end of the ventilation holes, and the second end is the proximal end of the ventilation holes;

[0058] The air outlet is connected to the first end of the ventilation hole 32 .

[0059] Specifically, the first end of the ventilation hole 32 can connect the dry warm air in the air guide cover 31 to the interior of the drum 1, and the other positions of the ventilation hole 32 can directly connect the dry warm air to the interior of the drum 1. Through the arrangement of the ventilation hole 32 and the air guide cover 31, the ventilation hole 32 can simultaneously connect the directly blown dry warm air and the guided dry warm air to the interior of the drum 1, so that the dry warm air can dry the clothes 11 in the central area and the edge area of ​​the drum 1 at the same time, so that the dry warm air can dry the clothes 11 more evenly, thereby improving the drying efficiency of the dryer and reducing the energy consumption of the dryer.

[0060] In some embodiments, the inclination angle a∈[20°, 80°] between the top of the air guide cover 31 and the bottom wall 2 is.

[0061] Specifically, the top of the air guide cover 31 and the bottom wall 2 have a certain inclination angle, and the inclination angle a is between 20° and 80°, so as to avoid the inclination angle being too small, resulting in less dry warm air entering, or the inclination angle being too large, resulting in the inability to disperse the dry warm air to the surroundings. The inclined air guide cover 31 can make the dry warm air entering the drum 1 better form spiral wind and disperse it to the surroundings, so as to evenly dry the clothes 11 inside the drum 1, thereby improving the drying efficiency of the dryer and reducing the energy consumption of the dryer.

[0062] In some embodiments, the wind guide structure 3 is spread over the bottom wall 2;

[0063] Alternatively, the air guide structure 3 is arranged at the edge area of ​​the bottom wall 2 , and a circular ventilation hole is arranged in the middle area of ​​the bottom wall 2 .

[0064] Specifically, the air guide structure 3 can be evenly arranged on the bottom wall 2, or the air guide structure 3 and the circular ventilation holes can be mixed and arranged on the bottom wall 2. In the case of mixed arrangement, the air guide structure 3 and the circular ventilation holes can also be evenly arranged.

[0065] Among them, the middle area can be within the half-circle at the center of the bottom wall 2, and the edge area can be the edge of the corresponding half-circle outside the bottom wall 2. The air guide structure 3 arranged on the outer circle can better guide the dry warm air to the clothes 11 on the inner edge of the cylinder 1, and the circular through holes in the inner circle can directly guide the dry warm air to the clothes 11 in the middle area. The combination of the two structures can better dry the clothes 11 in the cylinder 1.

[0066] In some embodiments, the wind guide structure 3 further has a first wind guide plate 33 , which is disposed on a side of the ventilation hole 32 away from the arc center, and the first wind guide plate 33 is connected to a side of the wind guide cover 31 .

[0067] Specifically, the first air guide plate 33 can be an extension of the air guide cover 31, so that the air guide cover 31 can take in more dry warm air when it rotates with the drum 1, thereby improving the air guide effect of the air guide cover 31, increasing the strength of the clothes 11 at the inner edge of the drum 1, and improving the drying efficiency of the dryer.

[0068] In some embodiments, the inclination angle b∈[20°, 90°] between the first air guide plate 33 and the bottom wall 2 .

[0069] Specifically, the first air guide plate 33 can be tilted at a certain angle relative to the bottom wall 2, and the tilt angle b is between 20° and 90°. The tilting at a certain angle can enable the first air guide plate 33 to better play a guiding role, allowing dry warm air to enter the air guide cover 31, and then enter the interior of the cylinder 1 from the air guide cover 31. The limitation of the tilt angle b can avoid the first air guide plate 33 from being tilted too small or too large, which will affect the air guiding effect of the first air guide plate 33.

[0070] In some embodiments, the wind guide structure 3 further has a second wind guide plate, which is located inside the wind guide cover 31 and is parallel to the top of the wind guide cover 31 .

[0071] Specifically, the second air guide plate can make the air guide cover 31 form an inclined air duct, so that the spiral airflow formed by the dry warm air introduced into the drum 1 by the air guide cover 31 can be stronger, thereby improving the drying effect of the clothes 11 at various locations on the inner edge of the drum 1, making the dry warm air dry the clothes 11 more evenly, thereby improving the drying efficiency of the dryer and reducing the energy consumption of the dryer.

[0072] In some embodiments, the air guide cover 31 is in a trumpet shape with an air outlet larger than an air inlet.

[0073] Specifically, the trumpet-shaped air guide cover 31 can make the dry warm air guided by the air guide cover 31 into the interior of the drum 1 more dispersed, and can quickly dry the clothes 11 at the inner edge of the drum 1 while also taking into account the clothes 11 at other positions, thereby improving the drying efficiency of the dryer and reducing the energy consumption of the dryer.

[0074] Embodiment 2

[0075] like Figure 7 and Figure 8 As shown, an embodiment of the present application also provides a drying system, comprising: the aforementioned drying drum and a drying air duct connected between the air outlet of the drying drum and the air guide structure; the drying air duct comprises a front air duct connected to the air outlet of the drying drum, a rear air duct 5 connected to the air guide structure and an intermediate air duct located between the front air duct and the rear air duct, the intermediate air duct is located at the bottom of the drying drum and flows through the heat pump device; the air outlet of the rear air duct 5 is directly opposite to the bottom wall of the drying drum.

[0076] Specifically, the warm air in the drying system is circulated by the centrifugal impeller 6 driven by the motor. When the centrifugal impeller 6 rotates, a negative pressure is formed on the side of the heat pump device 8. The dry warm air dried by the heat pump device 8 enters the drum through the rear air duct 5, the through holes on the rear side plate 4 and the air guide structure 3 on the drum chassis. The dry warm air contacts the clothes 11 in the drum, takes away the moisture on the clothes 11, and enters the dryer base 9 through the air duct under the door body 10. There is a heat pump device 8 in the air duct of the base 9, which is used to condense the moisture in the warm air, heat it after drying, form warm air of suitable temperature, and continue to circulate under the drive of the centrifugal impeller 6.

[0077] The rear air duct 5 in the drying system and the bottom of the drying barrel, that is, facing the bottom wall 2 of the cylinder 1, allows the dry warm air to be directly blown to the air guide structure 3, reducing the loss of the dry warm air, and through the air guide cover 31 and the ventilation holes 32 in the air guide structure 3, the dry warm air in the cylinder 1 can form a spiral airflow, and the clothes 11 at the inner edge of the cylinder 1 are also dried, so that the drying effect of the clothes 11 is more uniform, and the drying efficiency of the clothes 11 is improved, thereby reducing the energy consumption required for drying the clothes 11, reducing the time required for drying the clothes 11, and improving the customer's experience.

[0078] in, Figure 8 The direction of the arrow in the figure indicates the flow direction of the dry warm air.
