Specifically, the motor 2 is connect by shaft coupling 3 with the motor transmission shaft 6.Further, the shaft coupling 3
It is connect by transmission axle 4 with the motor transmission shaft 6.The i.e. described motor realizes that power passes by the secondary docking of the shaft coupling
It is defeated.In this way, can avoid damage of the microwave to motor, and also have by the outside that the motor is placed in the drying cavity
The space for having saved inside cavity of effect, convenient for microwave action in being entirely oven-dried object, to reach best drying effect.And
By processing two mounting grooves in the motor transmission shaft, consequently facilitating being docked with the simply described sealing structure realization of structure.
Wherein enclosure space is integrally formed by four part sealing plates in the sealing structure, and motor transmission shaft 6 is passed through the microwave drying
The mounting hole entirety environmental sealing of cavity 1, effectively prevents microwave from leakage.
Further, in order to realize ideal sealing effect, in one embodiment, referring to Fig. 2, each institute
Stating sealing plate includes gear part 8 and bending part 9, and the bending part 9 is set to the side of the gear part 8, wherein being located at described
The bending part 9 of two sealing plates of 6 top half of motor transmission shaft, which respectively corresponds, to be inserted in two mounting grooves, phase
The gear part for two sealing plates for being located at 6 top half of motor transmission shaft with answering mutually reclines, and is installed on described
On the side wall of microwave drying furnace cavity 1, positioned at the bending part 9 of two sealing plates of 6 lower half portion of motor transmission shaft
It respectively corresponds and is inserted in two mounting grooves, be correspondingly situated at two sealings of the motor transmission shaft lower half portion
The gear part of plate mutually reclines, and is installed on the side wall of the microwave drying furnace cavity.The structure of the i.e. described sealing plate 7 is band
There is the rectangular box structure on dovetail side, wherein the gear part is the dovetail part of rectangular box, the bending part is rectangular box
Main part.By the way that the sealing plate 7 is designed to such structure, so that each sealing in two mounting grooves
The bending part of plate is deeply inserted in the mounting groove, sets the sealing mounting hole to play the role of certain gear, further
So that the gear part for two sealing plates that horizontal direction is set side by side mutually reclines, and installed by setting gear part 8 on ground
In in the microwave drying cavity 1, can further seal in this way the motor transmission shaft 6 close to it is described installation hole peripheral seam
Gap.For example, two gear parts 8 mutually to recline are fixed by bolts on the microwave drying cavity 1.Institute each in this way
It states sealing plate one end to be fixedly installed in by bolt arrangement part on the side wall of the microwave drying cavity, the other end stablizes grafting
In in the mounting groove on the motor transmission shaft 6, the sealing plate steadily can be installed on the microwave drying cavity in this way
On.
In order to further increase the stability of the entire sealing structure, in one embodiment, referring to Fig. 3, often
The bending part 9 of one sealing plate is provided with connection flange 10, and the connection flange 10 is for being fixedly connected positioned at same institute
State two sealing plates 7 in mounting groove.I.e. positioned at 1 lateral wall of microwave drying cavity two sealing plates 7 it
Between connection realized by connection flange 10 on respective bending part 9.For example, described in two be located in the same mounting groove
