Technical field
The utility model relates to the kitchen appliance field, particularly a kind of radiation fan and have the electromagnetism stove of radiation fan.
Background technique
The radiation fan that uses in the electromagnetism stove of prior art is made up of following basic structure: blower tray, stator, flabellum.Stator includes stator frame, is connected in the circuit board of stator frame, reaches the power supply wiring that an end is welded in circuit board.Blower tray is provided with fixing column, stator is sheathed on the fixing column and by being full of to cooperate and realizes circumferentially fixing, yet this kind mode is deposited in use for some time, stator and fixing column matching loose can appear, cause flabellum stator frame oscillating motion in start and stop and running, the drive circuit board rocks, and makes that wiring and the circuit board root in the stator bears alternate load, causes the broken string accident after repeatedly using.Reduce fan and electromagnetism stove complete machine working life.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned problems of the prior art and a kind of long-life radiation fan is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: blower tray is provided with the stationary axle of fixed stator, and stator is set on the stationary axle, is provided with the bounding means that the restriction stator rotates between stationary axle and stator.
Aforementioned in a preferred embodiment bounding means can be located on the stator.
Aforementioned in another preferred embodiment bounding means is located on the stationary axle.Bounding means is a fin and one-body molded with stationary axle, and stator comprises position shelf, and position shelf is provided with the groove that cooperates with the stationary axle of blower tray, and the inwall of groove is provided with the draw-in groove that holds bounding means.
This enforcement is novel also to provide a kind of electromagnetism stove with radiation fan, radiation fan comprises blower tray and stator, and blower tray is provided with the stationary axle of fixed stator, and stator is set on the stationary axle, be provided with the bounding means that the restriction stator rotates between stationary axle and stator, bounding means is located on the stationary axle.
Stator and blower tray are closely fixed by being located at bounding means therebetween in the utility model radiation fan, the circumferential spacing means of fixation of stator and stationary axle utilization in this creation, prevent to become flexible when fan cooperates generation between stator and blower tray stationary axle in start and stop and running, thereby avoided the wiring in the stator and the joint of circuit board to bear alternate load, the broken string accident that causes, the working life of prolongation radiation fan and electromagnetism stove.

Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
As Figure 1-3, be the mode of execution one of a kind of long-life radiation fan 100 of the utility model, it comprises blower tray 1, stator 2, and and the flabellum 3 of stator 2 cooperatings.2 of blower tray 1 and stators are provided with the bounding means 4 that restriction stator 2 rotates.Blower tray 1 is provided with the stationary axle 11 of fixed stator 2, and stator 2 is set on the stationary axle 11, and bounding means 4 is located at 2 of stationary axle 11 and stators.
Stator former 2 comprises position shelf 21, and position shelf 21 is provided with the groove 22 that cooperates with the stationary axle 11 of blower tray 1, and the inwall of groove 22 is provided with the draw-in groove 23 that holds bounding means.Stator former 2 also comprises circuit board 24 that is fixed in position shelf 21 and the wiring 25 that is connected with power supply, and an end of wiring 25 is welded in circuit board 24.Position shelf 21 comprises steel framework 211, moulds framework 212 and is wound to steel framework 211 and mould the enameled cable 213 of framework 212, and an end of enameled cable 213 is electrically connected with circuit board 24.
When mounted, position shelf with stator 2 is inserted on the stationary axle 11 of blower tray 1 earlier, the bounding means 4 of stationary axle 11 is stuck in the draw-in groove 23 of position shelf 2, again metal axle sleeve 5 is pressed in the through hole 112 of stationary axle 11, then flabellum 3 is loaded on the support, flabellum 3 is provided with metal shaft 31 and passes metal axle sleeve 5, and radiation fan 100 comprises that also a U type snap ring 6 snaps in metal shaft 31 ends, and it is whole to make each assembly finally finish assembling.
This creation mode of execution two and aforementioned embodiments one be different be in: bounding means 4 is located on the stator 2, and stationary axle 11 surfaces of blower tray 1 are provided with the draw-in groove that cooperates with bounding means 4.
This enforcement is novel also to provide a kind of electromagnetism stove with radiation fan, and what its radiation fan adopted is the structure of aforementioned radiation fan 100.
In use, stator 2 is closely fixed by being located at bounding means 4 therebetween with the stationary axle 11 of blower tray 1 in the utility model; Utilize circumferentially spacing means of fixation, prevent to take place to become flexible when flabellum 31 stator 2 in start and stop and running cooperates with 11 of blower tray 1 stationary axle, thereby avoided the joint of wiring 25 and circuit board 24 in the stator 2 to bear alternate load, the broken string accident that causes prolongs 100 working lifes of radiation fan.
