Motor body 1 uses motor for double-ended drive ontology, and one end far from its output shaft is coaxially solid on the rotor of motor body 1
Surely there is countershaft 32, impeller 33 is coaxially fixed on countershaft 32, impeller 33 includes the concentrator bowl 331, Yi Jiduo connecting with countershaft 32
It is a to surround the arc-like sheet 332 being arranged at intervals on 331 inner wall of concentrator bowl.Concentrator bowl 331 is annular in shape and center axis thereof and electricity
The pivot center of 1 output shaft of machine ontology is overlapped, and side of the arc-like sheet 332 far from countershaft 32 is welded and fixed with 331 inner wall of concentrator bowl,
Arc-like sheet 332 is arc-shaped along the axial profile of motor body 1, and arc-like sheet 332 and concentrator bowl 331 are axial in angle.32 band of countershaft
Dynamic arc-like sheet 332, drives the air in concentrator bowl 331 to do centrifugal movement, air is after spiral boosting when arc-like sheet 332 rotates
Into between adjacent arc-like sheet 332, and motor body 1 is blowed under the guidance of arc-like sheet 332, improve 1 surface of motor body
Air velocity is accelerated overflowing for vapor and is dissipated, improves dehumidification efficiency.
Air guide ring 333 is provided on impeller 33 between 1 output shaft of motor body and concentrator bowl 331, air guide ring 333 is in
Funnel-form and air guide ring 333 and countershaft 32 are coaxial fixed, and air guide ring 333 is welded and fixed with arc-like sheet 332.Air guide ring 333 is by electricity
The side diameter of machine ontology 1 is greater than the other side, increases the opening area of 33 inlet side of impeller with this, facilitates the convergence of air, together
When reduce the opening area of 33 air side of impeller, improve wind pressure to improve the air velocity on 1 surface of motor body, improve motor sheet
The effect on moisture extraction of body 1.
The implementation principle of the present embodiment are as follows: before motor body 1 is opened, operator, which opens contact-making switch, keeps heating sheet 31 logical
Electricity heats motor body 1 by heating sheet 31, accelerates the evaporation rate of the water on motor body 1.Simultaneously vapor by
It is expanded outwardly after thermal expansion along convection holes 11 and stomata 12, accelerates the discharge of vapor with this.Air heats temperature increases simultaneously
Afterwards, the convection current aggravation of gas molecule, is accelerated the discharge of vapor with this, plays the effect of dehumidifying.Cowling 22 is opened simultaneously, this
When motor body 1 with extraneous air-flow exchange quickening, accelerate the drying of motor body 1 with this, accelerate the discharge of vapor.Simultaneously
Facilitate operator to open casing 2 and checks failure and maintenance.And it is reduced when the closing of cowling 22 and enters motor by convection holes 11
Dust in ontology 1 avoids convection holes 11 from blocking and dehumidifying is made to be obstructed.
Temperature sensor 4 detects the temperature of motor body 1, and heat gathers and triggers temperature and passes after motor body 1 is dried
Sensor 4, controller control contact-making switch and disconnect.Operator's slide-and-lock bar 53 later, it is same that the compression of spring element 532 generates elastic force
When concede space make barb 51 be inserted into sliding slot 521 in, check lock lever 53 spring element 532 elastic force effect under along the chute 521 sliding
When be engaged by clamping with barb 51, lock cowling 22 and fixing seat 52 with this, to lock cowling 22, avoid motor body
Cowling 22 occurs to loosen and make the unbalance generation noise of motor body 1 or break down when 1 operating.
When motor body 1 operates, motor body 1 drives countershaft 32 to rotate, the rotation of 32 impeller 33 of countershaft, 33 band of impeller
