The utility model solves the problems of the technologies described above adopted technical scheme: a kind of baking box back lampblack-preventing structure, comprise the fan blade of the inner side of liner being fixed on baking box, and the motor outside the inner bag being fixed on baking box, the hole that the axle that the inner bag of described baking box is provided with power supply machine passes, described fan blade is fixed on the shaft and is rotated along with the driving of axle, it is characterized in that: the axle between described inner bag and fan blade is fixed with and fan blade little fan blade separately, the blade of described little fan blade towards direction and fan blade blade towards direction contrary, and the diameter of little fan blade is greater than the diameter in described hole.
Also baking box back can not be entered in order to prevent the oil smoke when fan blade does not rotate, there is lampblack-preventing effect better, what described inner bag was provided with that the periphery of little fan blade with this matches one encloses recessed circle, and the periphery of described little fan blade is to inner bag curving and be positioned at described recessed circle.
In order to make lampblack-preventing better effects if, described little fan blade is disc-shaped part, and its periphery has the circle side face extended towards inner bag.
In order to keep fan blade and little fan blade, and the interval between little fan blade and inner bag, on the axle between described fan blade and little fan blade, fixed cover is provided with locating ring, the axle between described little fan blade and inner bag is arranged with a circle along the outstanding projection of the radial direction of axle.
Preferably, for the ease of fixed electrical machinery, the outside of described inner bag is provided with fixed head, and described motor is fixed on the outside of described fixed head, the hole that the axle that described fixed head is provided with power supply machine passes.
Compared with prior art, the utility model has the advantage of this baking box back lampblack-preventing structure, not only structure is simple, install easy to process, and can prevent the oil smoke of oven inner container from entering the motor overflowing and enter fan blade behind well, affect the running of motor, and then prevent the minimizing causing motor service life, and easy accessibility.
Accompanying drawing explanation
Fig. 1 is the sectional view of the baking box back lampblack-preventing structure of the utility model embodiment.
Fig. 2 is the enlarged drawing of the part A in Fig. 1.
Fig. 3 is the exploded view of the baking box back lampblack-preventing structure of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As Figure 1-3, the lampblack-preventing structure of the utility model embodiment comprises the fan blade 2 of the inner side of the back upper inner-liner 1 being fixed on baking box, and the motor 3 outside the back inner bag 1 being fixed on baking box, the outside of the inner bag 1 at the back of this baking box is provided with fixed head 4, motor 3 is fixed on the outside of fixed head 4, and the axle 31 fixed head 4 and inner bag 1 being respectively equipped with hole 41 and 11 power supply machine 3 passes, one end that the axle of motor 3 is positioned at the inner side of inner bag 1 is fixedly connected with described fan blade 2.Therefore, motor 3 can drive the rotation of fan blade 2 by axle 31.
Because the hole 11 this inner bag 1 supplying axle 31 pass is usually comparatively large, so motor 3 is polluted in the outside that the oil smoke inside inner bag 1 easily overflows inner bag 1 by this hole 11, and then cause fan blade 2 to seize up.Therefore, on this axle 31, a little fan blade 5 is provided with between inner bag 1 inwall and fan blade 2, the blade of this little fan blade 5 towards direction and fan blade 2 blade towards direction to arrange on the contrary, namely this fan blade 5 is towards side air-out in inner bag 1, and this little fan blade 5 should towards opposite direction air-out, this little fan blade 5 is also fixed on axle 31, and along with the driving of axle 31 and fan blade 2 coaxial rotation.In order to keep the interval between little fan blade 5 and fan blade 2, on this axle 31, a locating ring 6 is arranged with between little fan blade 5 and fan blade 2, in order to keep the interval between little fan blade 5 and inner bag 1, on this axle 31, be arranged with the radially outward outstanding projection 7 of a circle along axle 31 between little fan blade 5 and inner bag 1, this projection 71 can be that be fixed on also can be one-body molded with axle 31 on axle 31.The diameter of this little fan blade 5 is greater than the hole 41 and 11 on fixed head 4 and inner bag 11.
Preferably, this little fan blade 5 is discoid parts, and periphery has the circle side face 51 extended towards inner bag 1.So no matter run at fan blade or the effect preventing oil smoke from entering back motor when not running, can be played.The position that the inwall of described inner bag 1 matches with the side face 51 of little fan blade 5 is provided with the recessed circle 12 of a circle, therefore, the side face 51 of this little fan blade 5 just moves in this recessed circle 12, little fan blade 5 had both played the effect in the hole 11 stopped on inner bag 1, produce air-flow again and between fan blade 2, make to enter fan blade 2 oil smoke air-flow behind from inner bag 1 towards fan blade 2 direction, dotted arrow direction as shown in Figure 1, can to move with the axial direction of little fan blade 5 from fan blade 2 and change over tangential direction, scatter away to surrounding from the gap between fan blade 2 and little fan blade 5, prevent oil smoke from entering in fan blade 2 motor 3 behind.This little fan blade 5 also can be other shapes, and the blade that such as multi-disc is separated separately, or the blade of other shapes as long as its periphery is towards inner bag 1 curving, and are positioned at recessed circle 12.
This baking box back lampblack-preventing structure, not only structure is simple, installs easy to process, and can prevent the oil smoke of oven inner container from entering the motor overflowing and enter fan blade behind well, affect the running of motor, and then prevent the minimizing causing motor service life, and easy accessibility.
Although more than describe in detail preferred embodiment of the present utility model, should be expressly understood that, for a person skilled in the art, the utility model can have various modifications and variations.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
