In the present embodiment, food processor further includes the synchronous motor being located at below motor, radiator fan and synchronous motor It is sequentially connected, synchronous machine drives radiator fan is rotated to radiate to each component in engine base.

The advantage of this embodiment is that driving radiator fan rotation by the way that individual synchronous motor is arranged so that radiation air Fan can be controlled individually, when that need not radiate or not need motor rotation, can individually be controlled motor or synchronous motor, both be protected in this way Heat dissipation effect is demonstrate,proved, and does not expend electric energy, saves resource.

In addition to above preferred embodiment, the utility model also has other embodiments, and those skilled in the art can root It is made various changes and modifications according to the utility model, without departing from the spirit of the utility model, the utility model should all be belonged to Range defined in appended claims.
