The operation principle and the course of work of the present embodiment：

When food refuse is processed, food refuse is put into food refuse disposer by entrance along splash-proof casing 14 first In grinding chamber, then manually opened jettron, exports the unlatching letter of high level after jettron control circuit 6 is toggled Number, control process device brings into operation after single-chip microcomputer U8 receives the open signal of high level；Or can be sent out by remote terminal Wireless signal is penetrated, the wireless receiving circuit of processor receives the signal opened to single-chip microcomputer U8 outputs after wireless signal.

First, when polishing food refuse is started, single-chip microcomputer U8 exports the water delivery control signal of high level, water delivery control electricity Road 3 turns in response to the water delivery control signal of high level, so that magnetic valve M is opened, after magnetic valve M is opened, water source is ceaselessly To being poured in the cavity 101 of processor so that the food refuse in processor becomes wet and slippery, is difficult stuck easy polishing.

After 3 seconds, single-chip microcomputer U8 makes power control circuit be powered to motor, and motor receives power control circuit offer After operating current i.e. start drive the forward direction of sanding apparatus 11 rotation, the uninterrupted water delivery of water delivery device 12 during polishing, So referred to as wet polishing, food refuse is polished in the bull ring 103 on the top of cutterhead 111 first, with turning for cutterhead 111 Dynamic, positive cutter tooth 1112 constantly cuts food refuse, and knife hammer 1111 constantly clashes into food refuse, on the one hand can be by food refuse Smash, on the other hand cause that food refuse is not stalled with the mixture of water in bull ring 103 dynamic, then food refuse is ground The lasting cutting of knife wall 1032 for enclosing 103 bottoms is smashed, and as food refuse is constantly broken, the small rubbish of particle is directly by water Stream is washed away, and the larger rubbish that cannot be washed away of remaining particle forms vortex after mixing with water, and is located at the side on the top of bull ring 103 Tooth 1033 can be formed when vortex is rotated in food refuse and constantly cut food refuse, meanwhile, side tooth 1033 is along cutterhead 111 directions for rotating forward are stepped to be risen and is spaced, and the direction of arrangement is consistent with the ascent direction of vortex, 1033 pairs, side tooth Vortex has barrier effect, so can be on the track that vortex is formed to being vortexed the suppression for carrying out successively.

After food refuse is polished to sufficiently small, i.e., can under the flushing of current by the perforate on cutterhead 111 or Gap between knife wall 1032 is leak into downwards between chassis 113 and cutterhead 111, as grind section 112 is continuous with respect to chassis 113 Rotate, the projection 1131 on cutter tooth 1122 and chassis 113 in grind section 112 is mutually compressed, and the food refuse that will be smashed enters The secondary polishing of row, polishing it is finer.

During polishing, the current value of the moment of current detection circuit 1 detection motor simultaneously exports corresponding electric current Detection signal, the comparison module 21 of single-chip microcomputer U8 compares current detection signal and turns to switching letter to export with the size of first threshold Number, when food refuse is polished to granular size reaches the first preset value, because particle diminishes, motor is when rotation is polished Wait more laborsaving, so that the electric current of motor is smaller, reached when the current value of motor or during less than first threshold, now single-chip microcomputer The water delivery stop signal of the output of comparison module 21 of U8 makes timing module 22 start first time timing, and timing module 22 exports low electricity The first flat timing signal, water delivery control circuit 3 stops conducting after receiving low level first timing signal, and then makes electromagnetism Valve M is turned off, and processor stops water inlet, and sanding apparatus 11 are still operated, i.e., processor proceeds by the dry of very first time preset value Polishing, during dry rubbing, knife hammer 1111, positive cutter tooth 1112 and grind section 112 are clashed into, cut food waste particles, by bulky grain Food refuse further crush, simultaneously for some as the big rubbish of the class light weight list hardness of bone one, dry rubbing will not make These rubbish are floated, and more broken compared to what wet polishing can polish, treatment effect is more preferable.

When wet polishing and dry rubbing is carried out, if the current value of motor is more than the second preset value, it is judged to sanding apparatus 11 are stuck, and motor easily breaks down in this condition for a long time, and the now output of comparison module 21 of single-chip microcomputer turns to switching letter Number to steering controling circuit 4, by changing power supply polarity to change the rotation direction of motor, such as when the positive polishing card of processor When dead, comparison module 21 exports the steering switching signal of high level, and steering controling circuit 4 receives the steering switching letter of high level Motor reverse power supply is given after number, so that processor starts reversion and is polished, after cutterhead 111 and the reversion of grind section 112, card Will be unclamped after reversion to the rubbish between the positive cutter tooth 1112 and knife wall 1032 on cutterhead 111, meanwhile, it is stuck in chassis Rubbish between 113 projection 1131 and the cutter tooth 1122 of grind section 112 also can be pushed out or squeeze in reversion, so as to invert Effectively solve some common card machine situations.

In addition, though suppression of the side tooth 1033 when wet polishing is inverted on bull ring 103 due to sequence to being vortexed Declines processed, but anti-cutter tooth 1113 is located at the inner side of cutterhead 111, and when rotated, the eddy current effect for causing is compared to outside Positive cutter tooth 1112 weaken, cancelled out each other after the influence superposition of the two, eddy current effect during reverse wet polishing can't strengthen, this The direction deflection inner side of outer anti-cutter tooth 1113, further suppress the formation of vortex, so that influence of the eddy current effect to polishing It is smaller.

After first time timing terminates, timing module 22 carries out second timing and exports the second timing signal of high level, The control signal that water delivery control circuit 3 receives high level opens magnetic valve M to re-start bath, and wash by water while after Continuous rotary-grinding device 11 so that processor cleaning it is more clean, by after the duration of the second time preset value, second Timing terminates, and now single-chip microcomputer U8 controls power control circuit stops to machine switched off, so as to finish whole polishing, realizes Capable of being opened by one key, automatically grinding, Based Intelligent Control, to using bringing convenience.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.Should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
