[0002] Dryer is widely used in many industries, especially in traditional industries such as textile, printing and dyeing, food processing, its high efficiency and low energy consumption characteristics make it become the key equipment to improve production efficiency. In addition, with the rise of agricultural modernization and rural e-commerce, the demand for drying equipment in agricultural product processing industry is also growing.

[0003] However, at present, some drum drying devices cannot effectively utilize heat due to single design structure, resulting in high required drying temperature and long time consumption, which seriously affects the thermal energy conversion rate. The root cause lies in that in the existing dryer, hot air enters the drum through the densely arranged small holes in the upper half of the drum for heat exchange with clothes, and then flows out through the small holes in the lower half of the drum.

Moreover, the more clothes required to be dried in the drum, the greater the air resistance, resulting in heat loss. As a result, most of the hot air is lost. Once the hot air is lost, higher temperature and longer time are required to dry the objects to be dried. SUMMARY

[0036] Refer to the instruction manual. Figures 1 to 5 A preferred embodiment of the dryer according to the present invention, which reduces heat loss, will be described in detail below:

[0037] The dryer that reduces heat loss includes a mounting body 10, a drum assembly 20, a drying assembly 30, and a set of air-jetting assemblies 40.

[0038] The installation body 10 forms an installation cavity 11, wherein the installation body 10 forms an opening 12 communicating with the installation cavity 11 and capable of being capped towards a substantially horizontal direction at the side of the installation body 10. In addition, the installation body 10 further forms an air inlet 13 and an air outlet 14 communicating with the installation cavity 11.

[0039] The drum assembly 20 comprises a rotating drum 21 and a driving unit 22, wherein the rotating drum 21 is rotatably connected to the driving unit 22, and the rotating drum 21 is rotatably held in the installation cavity 11 in a substantially horizontal direction.

[0040] An opening 2101 is formed at the axial end of the rotating drum 21, wherein the opening 2101 is arranged towards the opening 12, and the outer wall of the rotating drum 21 is provided with a plurality of holes for the hot air to enter or flow out.

[0041] Specifically, the driving unit 22 comprises a mounting bracket 221, a motor 222, a belt 223, a belt pulley 224 and a transmission shaft 225, the mounting bracket 221 is fixedly mounted on the installation body 10, the motor 222 is fixedly mounted on the mounting bracket 221, one end of the transmission shaft 225 is fixedly mounted on the rotating drum 21, and the other end is fixedly connected with the belt pulley 224, one end of the belt 223 is rotatably mounted on the output end of the motor 222, and the other end is rotatably mounted on the belt pulley 224. When the motor 222 rotates in the forward direction, the output end of the motor 222 drives the belt 223 to rotate clockwise, and in turn the belt 223 drives the belt pulley 224 to rotate clockwise, the belt pulley 224 drives the transmission shaft 225 to rotate, and the transmission shaft 225 transmits the torque to the rotating drum 21, thereby driving the rotating drum 21 to rotate.

[0042] In this way, on the one hand, the moisture of the clothes dried in the rotating drum 21 can be discharged from the holes of the rotating drum 21 through the centrifugal principle, and in turn discharged from the air outlet 14, on the other hand, the required clothes can be uniformly heated by the rotation of the rotating drum 21, thereby improving the working efficiency of the dryer capable of reducing the loss of hot air.

[0043] Further, a through hole is formed in the installation body 10 and sealingly fitted with the transmission shaft 225.

[0044] The drying assembly 30 is arranged in the installation body 10, and is capable of forming hot air, wherein the formed hot air can be introduced into the drum assembly 20 from the radial direction of the rotating drum 21 through the holes on the rotating drum 21 via the air inlet 13, and then flows out via the air outlet 14.

[0045] As a preferred, the drying assembly 30 is arranged to form hot air from the top of the installation body 10 downwardly toward the drum assembly 20 in the installation cavity 11. In addition, the air outlet 14 is arranged at the bottom of the installation cavity 11, and is arranged opposite to the air inlet 13, so as to effectively prolong the time for the hot air formed by the drying assembly 30 to stay in the rotating drum 21.

[0046] In particular, the drying assembly 30 comprises a heating member 31 and a blowing member 32, both of which are fixedly arranged in the installation body 10, and the heating member 31 is arranged on the hot air flow path formed by the blowing member 32, wherein the outlet of the blowing member 32 is communicated with the air outlet 14.

[0047] It is worth mentioning that the drying machine capable of reducing the loss of hot air comprises at least one set of wind binding assembly 40, which is arranged in the installation cavity 11 in a manner of binding the hot air flowing out of the air outlet 14 to pass through the rotating drum 21.

[0048] In one embodiment, one set of the wind binding assembly 40 is arranged at the air outlet 14 and between the outer wall of the rotating drum 21 and the air outlet 14, so as to bind the hot air formed from the radial direction of the rotating drum 21 to exchange heat with the clothes in the inner cavity of the rotating drum 21 via the holes on the rotating drum 21, and then be guided out of the air outlet 14.

[0049] In another embodiment, at least one set of the wind binding assembly 40 is arranged between the air inlet 13, the outer wall of the rotating drum 21 in the installation cavity 11 and the drying assembly 30.

[0057] Further, the mounting body 10 is provided with a filtering lint collecting box 60 near the air outlet 14, so that the lint generated by the clothes during the rotation of the rotating drum 21 can be discharged to the filtering lint collecting box 60 through the holes of the rotating drum 21, thereby being cleaned and improving the working stability of the drying machine capable of reducing hot air loss.

[0058] Specifically, the drying machine capable of reducing hot air loss further comprises an adjusting structure 70 comprising at least one waist-shaped hole 71 and at least one locking element 72, wherein the waist-shaped hole 71 is arranged on the mounting plate 41 and the mounting body 10, and the locking element 72 is installed on the waist-shaped hole 71.

[0059] Specifically, a plurality of axial mounting plates 411 and a plurality of arc-shaped mounting plates 412 are installed on the air inlet 13 and the air outlet 14, wherein the axial mounting plates 411 are fixedly installed on the axial direction of the rotating drum 21 through the waist-shaped holes of the axial mounting plates 411 and the waist-shaped holes 71 of the adjusting structure 70 by using bolts and other fasteners, the arc-shaped mounting plates 412 are fixedly installed on the radial direction of the rotating drum 21 through the waist-shaped holes of the arc-shaped mounting plates 412 and the waist-shaped holes 71 of the adjusting structure 70 by using bolts and other fasteners, and the mounting positions of the axial mounting plates 411 and the arc-shaped mounting plates 412 can be adjusted in time according to the rotating position of the rotating drum 21 through the waist-shaped holes 71 of the mounting body 10.
