The main function of the arranged moisture exhaust and fresh air heat recovery unit 12 is to effectively discharge moisture outdoors and at the same time recover heat back into the room, achieving the purpose of more energy-saving operation.
[0025] The central uniform heat conduction mechanism 2 includes a base 21 fixedly installed on the top surface of the floor drying kiln 1, and a first side frame 22 and a second side frame 23 are fixedly installed on both sides of the base 21. A plurality of groups of equally spaced circulation channels 24 are penetrated through the first side frame 22 and the second side frame 23.

[0029] It should be particularly noted here that the moisture exhaust and ventilation heat recovery unit, the temperature probe, and the digital display temperature controller are all prior arts, and no more elaboration will be made here.
[0030] In this embodiment, the implementation scenario is specifically as follows: when drying solid wood floors, the solid wood floors to be dried can be stacked at intervals with a certain gap on the floor drying rack 3 in sequence.

At the same time, the door body 111 is closed, and then the overall equipment is started to run. At this time, the air energy steam generator 4 generates steam, which is introduced into the interior of the floor drying kiln 1 between the first side frame 22 and the second side frame 23 on the top surface through the air outlet pipe 5. At the same time, the steam is conveyed in the direction away from each other by multiple groups of first heat conduction fans 25 and second heat conduction fans 26 to both side walls of the floor drying kiln 1. At the same time, under the action of the return air axial flow fan 61, it passes through the floor drying rack 3 to the center of the interior of the floor drying kiln 1, and finally returns through the return air pipe 6 and circulates. When the temperature inside the floor drying kiln 1 rises to a certain value, the electric hot air blower 7 works, absorbs and heats the air recovered through the return air pipe 6, and then is introduced through the air outlet pipe 5 again and circulates continuously. After drying, the door body 111 is opened, and the floor drying rack 3 is moved out. Overall, by increasing the number of circulating air and changing the direction of the circulating air, the uniformity of temperature distribution can be improved, effectively enhancing the drying uniformity of the solid wood floor, thereby greatly reducing the expansion and contraction rate of the solid wood floor.
