[0027] A return air duct 7 is installed at the top of the drying chamber 1. A return air fan 8 is installed on the right side of the return air duct 7. A dehumidification outlet 9 is installed in the middle of the top of the drying chamber 1. The top left side of the return air duct 7 is connected to the drying host 11 through a return air pipe 10. An air inlet pipe 12 is installed on the right side of the drying host 11, and the right side of the air inlet pipe 12 is connected to the drying chamber 1. The inspection door assembly 6 includes a door frame 61, a support frame 62, a screw assembly 63, a rear door leaf 64, an elastic sealing block 65, a front door leaf 66, a movable rod 67, an operating rod 68, and a collar 69. The support frame 62 is fixed on the left side of the door frame 61. A fan 8 is installed on the rear side of the inside of the door frame 61. The room is equipped with a rear door 64, and an elastic sealing block 65 is provided on the right side of the rear door 64. The elastic sealing block 65 is fixedly connected to the door frame 61. A front door 66 is provided on the front side of the interior of the door frame 61. Screw assemblies 63 are connected to the left sides of both the rear door 64 and the front door 66. Both sets of screw assemblies 63 are connected to the support frame 62. The right side of the interior of the front door 66 is penetrated by a movable rod 67. The front end of the movable rod 67 is fixedly connected to the operating rod 68. A collar 69 is fixed to the rear end of the movable rod 67. The rear end of the door frame 61 is fixedly connected to the front right side of the drying room 1. The rear side of the door frame 61 is connected to the drying room 1 through a connecting door 4.

[0028] The inspection frame assembly 5 includes a support frame 51, a connecting block 52, and a crossbar 53. The connecting block 52 is fixed to the right side of the front end of the support frame 51, and the right end of the crossbar 53 is fixedly connected to the connecting block 52. The support frame 51 fits against the left and right side walls inside the door frame 61, and the collar 69 is fitted onto the outside of the crossbar 53 and is slidably connected to the crossbar 53.

[0029] A slot 641 is provided in the middle of the right side of the rear door 64, and the position of the slot 641 is horizontally aligned with the position of the sealing block 654. The front end face of the sealing block 654 is inclined, and both the sealing block 654 and the connecting block 52 are in contact with the inner wall of the slot 641. When the support frame 51 moves to the front end of the rear door 64, the slot 641 is blocked by the sealing block 654. When the support frame 51 moves backward into the drying chamber 1, it squeezes the sealing block 654, causing the sealing block 654 to shrink. After the rear door 64 is closed, the inner wall of the slot 641 is inserted into the connecting block 52, and the slot 641 is blocked by the connecting block 52 to prevent the heat inside the drying chamber 1 from being lost through the slot 641.

[0030] A cooling fan is installed at the top of the door frame 61, and a temperature sensor is installed inside the door frame 61. The temperature sensor detects the temperature inside the door frame 61, and the cooling fan exhausts heat from the inside of the door frame 61.

[0031] Please see Figure 5An energy-saving circulating drying device, wherein the elastic sealing block 65 includes a limiting frame 651, a slider 652, a spring 653 and a sealing block 654. The slider 652 is provided on the left side inside the limiting frame 651. The right side of the slider 652 is elastically connected to the right side wall inside the limiting frame 651 through the spring 653. The right end of the sealing block 654 extends into the limiting frame 651 and is fixedly connected to the slider 652. The limiting frame 651 is fixed inside the right side wall of the door frame 61.

[0032] Please see Figure 6 An energy-saving circulating drying device includes a screw assembly 63 comprising a movable plate 631, a screw 632, a limiting rod 633, and a motor 634. The upper and lower sides of the interior of the movable plate 631 are transversely penetrated by the screw 632 and the limiting rod 633, respectively, and the inner wall of the movable plate 631 is threadedly connected to the screw 632. The output shaft of the motor 634 is connected to the screw 632 via a coupling. The motor 634 is fixed to the left side of the support frame 62. The left and right ends of the limiting rod 633 are fixedly connected to the support frame 62 and the door frame 61, respectively. The right side of the screw 632 is rotatably connected to the left side wall of the door frame 61 via a bearing seat. The movable plates 631 of the two sets of screw assemblies 63 are fixedly connected to the rear door 64 and the front door 66, respectively.

[0033] When using it, first place the items to be dried on the drying rack 3 and the support frame 51, open the double door 2, push the drying rack 3 into the drying room 1, and then close the double door 2.

[0034] During the installation of the support frame 51, the movement of the front door 66 and rear door 64 is controlled by the motors 634 of the two sets of screw assemblies 63. The motors 634 drive the screws 632 to rotate via their output shafts. The rotation of the screws 632 drives the movable plate 631 to move through the threaded engagement with the movable plate 631. The movable plates 631 of the two sets of screw assemblies 63 respectively drive the front door 66 and rear door 64 to move. Pulling the operating lever 68 forward causes the operating lever 68 to drive the collar 69 to move forward via the movable lever 67. By controlling the front door 66 to open, the support frame 51 is pushed into the inspection door assembly 6. Inside, at this time, the crossbar 53 at the front end of the support frame 51 is aligned with the collar 69 laterally. The front door 66 is closed, so that the collar 69 on the back side of the front door 66 is fitted onto the outside of the crossbar 53. The rear door 64 is opened, and the operating lever 68 is pushed to push the support frame 51 into the drying chamber 1. The support frame 51 moves backward to press the sealing block 654, so that the sealing block 654 contracts, and the connecting block 52 moves to the position of the sealing block 654. Then the rear door 64 is closed, and the slot 641 on the right side of the rear door 64 is inserted into the connecting block 52 to ensure the sealing effect of the rear door 64 and prevent the heat inside the drying chamber 1 from being lost through the slot 641.

[0035] When drying the items, the drying host 11 generates hot air and blows it into the drying chamber 1 through the air inlet pipe 12 to dry the items. The hot air is also blown into the return air duct 7 through the return air fan 8 and then introduced into the air box of the drying host 11 through the return air duct 10 to recycle the hot air and achieve energy saving. The temperature and humidity inside the drying chamber 1 are monitored by the temperature and humidity sensor. When the humidity inside the drying chamber 1 is high, the water vapor is discharged through the vent 9.

[0036] During the drying process, when it is necessary to check the drying status of the dried goods, the rear door 64 is opened, and the front door 66 is closed to reduce heat loss inside the drying chamber 1. The support frame 51 is moved forward into the door frame 61 by the operating lever 68, and the rear door 64 is closed. At this time, the sealing block 654 is pushed out by the elastic potential energy generated by the spring 653 and inserted into the slot 641 on the right side of the rear door 64 to seal the slot 641. The cooling fan on the door frame 61 then ventilates the interior of the door frame 61. The heat dissipation mechanism prevents burns from hot air inside the door frame 61. After heat dissipation, the front door 66 can be opened to check the drying status of the items on the support frame 51. After the check is completed, if it is necessary to continue drying the items on the support frame 51, the front door 66 is closed, the rear door 64 is opened, the inspection frame assembly 5 is moved into the drying chamber 1 for re-drying, and the rear door 64 is closed. This allows for the inspection of the drying status of the items during the drying process, which helps to determine the required drying time and improve the drying effect.
