Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through an intermediary, so to speak, communicating between the two elements. The specific meaning of the above terms in the present invention can be understood as specific cases to those skilled in the art. The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1-3, the air oven with a low overall height of the present invention includes a core 1 and a detachably connected housing 2, a space is left between the top side of the core 1 and the housing 2, a protective housing 3 is convexly disposed on the top side of the core 1, one side of the protective housing 3 is communicated with the outside air, a fan 4 is rotatably connected in the protective housing 3, and a rotating shaft of the fan 4 passes through the protective housing 3 and is detachably connected with a driven gear 5; the side that lies in protective housing 3 on the top side of core 1 still is equipped with motor 6, and the last detachable connection of motor 6 has driving gear 7, and driving gear 7 meshes with driven gear 5 mutually, and shell 2 corresponds driving gear 7 and driven gear 5's position still is equipped with flip 8. The utility model discloses utilize the linkage of motor 6 and gear, drive fan 44, effectively reduce the total height of complete machine appearance, save complete machine cost of manufacture, also can make the effective use space of furnace chamber bigger to the accessible lifts flip 8 at shell 2 top sides and changes the gear, thereby realizes at the uniform velocity of fan blade, with higher speed or rotation at a slow speed. This device is through locating motor 6 in one side, further utilize the space between core 1 and the shell 2, compare in prior art need locate the top of fan with driving motor etc. and cause the distance between core 1 top side and the shell 2 top side too big, this device can reduce the complete machine height relatively, fan 4 cooperation protective housing 3 protrusion in core 1 top side, one side of protective housing 3 is through the pipeline of induced air and the louvre intercommunication of core 1 dorsal part department, can be equivalent to going into the wind gap and let fan 4 drive new trend to the heating tube heating, and blow to waiting to roast food, so the cavity of fan 4 below just can have more usage spaces, so that the setting of heating tube etc. and motor 6 drives the rotation of fan 4 through driving gear 7 and driven gear 5's transmission, just also can make the difference in height between core 1 top side and the shell 2 reduce to the height that is a little higher than motor 6, and according to the actual load demand, change different driving gear 7 and driven gear 5, just can be under the condition that need not change motor 6's rotational speed, directly change fan 4's rotational speed, thereby can adopt motor 6 that the height is lower cost is lower as the driving piece.

Furthermore, two sides of the motor 6 extend outwards to form mounting seats 9, and the bottom of the mounting seat 9 is fixedly connected with the top side of the core body 1 through screws. The motor 6 is secured to the top side of the core 1 by inserting screws, with the bottom extending out of a sufficient position, by means of a mounting 9 in the form of a Z, thus ensuring a stable and detachable connection of the motor 6. And still be equipped with between driving gear 7 and driven gear 5 and protective housing 3 and motor 6 and connect baffle 10, the bottom edge of connecting baffle 10 outwards extends and is used for being connected with the top side of protective housing 3 and mount pad 9, and the position that corresponds fan 4 and motor 6 on connecting baffle 10 is equallyd divide respectively through bearing and the bell and spigot joint of corresponding rotation axis mutually. One end of the connecting partition plate 10 is fixed with the protective shell 3, and the other end of the connecting partition plate is matched with the mounting seat 9, so that the motor 6 is wrapped and protected to a certain extent. Moreover, the top side of the connecting partition plate 10 is a plane, and the bottom of the connecting partition plate 10 is in smooth transition and is respectively matched with the heights of the protective shell 3 and the mounting seat 9. The connecting partition 10 serves to fix and protect the motor 6 by connecting the protective case 3 and the motor 6, and also to relatively fix the protruding heights of the two rotation shafts through bearings, and to align the positions above the motor 6 and the protective case 3, so that the driving gear 7 and the driven gear 5 are installed and engaged with each other, are not easily separated when rotated, and allow the gears to be relatively separated from the fan 4 and the motor 6.

And wherein, this device still includes layering 11, and driving gear 7 and driven gear 5 are equallyd divide and rotate through the erection column respectively and connect on the both ends of layering 11, and the bottom of two erection columns is respectively with the rotating shaft joint of fan 4 and motor 6. The layering 11 mainly connects driving gear 7 and driven gear 5, so that replace together, the erection column rotates with layering 11 relatively and is connected, driving gear 7 and driven gear 5 just can directly fix the cup joint on the erection column, and the protrusion of erection column bottom forms the pothook, only need with its joint to fan 4 or motor 6's rotation axis top, can make motor 6 loop through driving gear 7 and driven gear 5 and link mutually with fan 4, like this when dismantling the change gear train, driving gear 7 and driven gear 5 just can install in place more conveniently, need not to carry out further adjustment once more to the meshing condition etc.. The transmission ratio of the driving gear 7 and the driven gear 5 is 1:2-2:1, the transmission ratio of the driving gear 7 and the driven gear 5 can be set to 1:2, 1:1, 2:1 and the like, and under the condition that the rotating speed of the motor 6 is not changed, the fan 4 is respectively corresponding to the operating modes of low speed, medium speed and high speed so as to adapt to different loads. Further, the height of the protective case 3 is greater than that of the fan 4 to facilitate installation of the fan 4.
