Description

Kitchen waste disposer

Technical Field

The utility model belongs to the technical field of machinery, a kitchen garbage disposer is related to, especially a kitchen garbage disposer's shearing mechanism.

Background

The kitchen waste disposer is mainly used for treating large, small, hard and soft wastes which are easy to deteriorate in daily life in families, restaurants, hotels and dining halls, and comprises the following steps: melon and fruit peel, vegetable root and leaf, fresh corncob, shrimp and crab peel, poultry ossicle, fishbone, thin shell skin, leftover vegetable and rice and other easily-rotten garbage. The main structure of a household garbage disposer comprises a shell with an inlet and an outlet, and a grinding mechanism arranged in the shell, wherein kitchen garbage enters from the inlet and is ground by the grinding mechanism and then discharged from the outlet. Therefore, the core structure of the grinding mechanism is a grinding mechanism which comprises a gear ring and a cutter head matched with the gear ring, the grinding mode is that a plurality of rugged rough surfaces are arranged on the gear ring, the garbage materials with larger shapes are firstly crushed into small particles by a fixed impact block on the upper side surface of the cutter head, and the small particles are pushed by the impact block to be finely ground on the rough surface of the gear ring to form powder or smaller particles meeting the requirements. For example, the composite cutter head of a food waste disposer disclosed in chinese patent application No. 201510390730 has a first cutter head fixed to the first cutter head and a forked block integrated with the upper part thereof, a fork point located at the edge of the disk and a fork rod pointing to the center of the disk, and a second cutter head fixed to the first cutter head and opposite to the first cutter head and also having a forked block and a cutter rod above the tail thereof. The first and second knife blocks fixed on the first knife disc and the convex teeth of the knife ring rotate relatively at high speed to beat and crush the food waste into granular slurry at high speed. The grinding type kitchen waste disposer is often stuck by hard particles with larger shapes during grinding due to the fact that particles crushed by impact are not fine enough, so that a motor is burnt, and stability is not high.

In order to solve the problems, one solution is to enlarge the gap between the impact block and the gear ring to solve the problem of grinding seizure, so that the probability of seizure of the cutter head can be reduced. Although the improved structure through the expanded distance can prevent the impact block from being stuck to a certain extent, the broken particles hit by the impact block are not in accordance with the requirement of direct discharge, and the overlarge particles can influence secondary grinding and further influence stability.

The solution that still commonly uses is the power of increase motor, directly pulverizes the rubbish that blocks through bigger motor moment of torsion, but the ring gear of abrasive type refuse handling machine all is through sheet metal structure, and too big moment of torsion can make the ring gear warp and lead to the grinding effect variation, and then influences stability to the energy consumption is higher.

Disclosure of Invention

The utility model discloses there is above-mentioned problem to current technique, has provided a surplus garbage disposer in kitchen, the utility model aims to solve the technical problem that how to make surplus garbage disposer in kitchen stability better.

The utility model discloses a following technical scheme realizes: the utility model provides a kitchen garbage disposer, includes the casing, is equipped with annular ring gear and sets up the relative ring gear pivoted blade disc in the ring gear in the casing, its characterized in that, the interior anchor ring of ring gear has interval distribution's cutting tooth the side of going up of blade disc articulates there is two at least cutting knives, at least one blade of cutting knife can be by to cutting tooth and with cut the tooth and form the shearing.

The working process of the kitchen waste disposer is as follows:

the cutter head is driven by the motor to rotate at a high speed, kitchen garbage materials falling into the upper surface of the cutter head can be thrown onto the inner annular surface of the gear ring under the action of centrifugal force, the cutting knife hinged on the cutter head is sheared by the gear ring and the cutting teeth on the gear ring under the action of centrifugal force, the garbage materials with larger shapes are pushed to move relative to the gear ring during shearing, because the inner annular surface of the gear ring is provided with the cutting teeth which are distributed at intervals, a layer of the surface layer of the garbage materials with larger particles is sheared off by the cutting teeth under the shearing action of the cutting knife and the cutting teeth, one part of the sheared garbage materials can be remained between two adjacent cutting teeth, the other part of the sheared garbage materials falls into the upper surface of the cutter head and is thrown onto the gear ring again under the action of centrifugal force, and the garbage materials remained between the two adjacent cutting teeth can be sheared with, when the garbage materials left between the cutting teeth are sheared into small particles meeting the requirements, the garbage materials fall to the lower part of the cutter head along the gaps between the cutting teeth, and the process is repeated until all the garbage materials are sheared into small particles meeting the requirements.

This kitchen remains garbage processor adopts articulated cutting knife and ring gear to form and cuts and handle the rubbish material, only directly becomes the tiny particle that meets the requirements with the independent mode of shearing with the rubbish material, does not set up any striking piece through striking breakage on the blade disc, has abandoned through striking piece striking breakage and has ground into likepowder abrasive treatment mode through the ring gear. Compared with the existing mixed garbage material treatment modes such as impact crushing, cutting, grinding and the like, the method only adopts a shearing mode, and particularly, the method also adopts shearing to treat hard garbage with large shape and is difficult to realize. When the kitchen waste disposer meets waste materials with larger shapes and hard shapes, the kitchen waste disposer only cuts the waste materials. Especially when meeting the especially big stereoplasm rubbish of shape, the cutting knife also can swing to the maximum position and make blade and cutting tooth form the biggest opening to adapt to the especially big stereoplasm rubbish material of shape, avoid dying the cutter head card, and the moment of blade is big more when the distance of blade and the axle center of cutter head is more nearest, and then can have sufficient power cutting and cut off a little rubbish material when the blade passes through especially big stereoplasm rubbish material, can not cause the cutter head card to die and then lead to the condition that the motor burns out, and stability is better. Therefore, the conventional method that the cutter must be fixed on the cutter disc to normally cut is solved by the shearing mode of the structure, a better shearing effect is achieved, and the cognition that the object is difficult to shear by the hinged cutter is overcome. The shearing here is the motion that two staggered opposite cutting edges are close to each other, when one cutting edge is motionless, the cutting edge that another moving cutting edge is motionless is shearing the cutting, and two staggered cutting edges can have the interval, just can cut out littleer granule like the scissors when the interval of staggering the cutting edge is little enough. The present case utilizes articulated cutting knife and cutting tooth cooperation, thereby reduces gradually after cutting the rubbish material of large granule and cuts the clearance gradually and form the tiny particle that meets the requirements.

In foretell kitchen garbage disposer, the cutting knife includes the handle of a knife of rectangular shape, and the inner of handle of a knife articulates on the blade disc, and the outer end of handle of a knife has the block that exceeds handle of a knife thickness, the outward flange of terminal surface is first blade before the block, the inward flange of terminal surface is higher than handle of a knife thickness part and is the second blade before the block. When rubbish material granule is too big, cut the rubbish material by the second blade in advance, cut by first blade after rubbish material granule reduces again. The increased weight of the block can also increase the shear force.

In the kitchen waste disposer, the cutter is provided with a yielding groove which can increase the distance between the cutting edge and the inner ring surface of the gear ring. The further increase clearance can make the rubbish material of big shape handle to can not die the cutter head card, increase the stability of work.

In the kitchen waste disposer, the abdicating groove is arranged on the rear end face of the knife handle, and the front end face of the knife handle opposite to the abdicating groove is convex. The structure makes up the problem that the strength of the cutter handle is reduced by arranging the abdicating groove.

In the kitchen waste disposer, the cutting teeth are divided into at least two types, namely rough cutting teeth and finish cutting teeth, and the length of the finish cutting teeth is longer than that of the rough cutting teeth, so that the distance between the notches formed at the top ends of the finish cutting teeth is smaller than that between the notches formed at the top ends of the rough cutting teeth.

In the kitchen waste disposer, a rough cutting ring is arranged above the gear ring, a plurality of cutting guide surfaces which protrude towards the direction of the ring center and are inclined downwards are arranged on the inner ring surface of the rough cutting ring, the outer edge of each guide surface is a cutting edge, and a notch is formed between one guide surface and the top end surface of one fine cutting tooth. The guide surface and the cutting tooth top end surface form a notch, and the guide surface can enable garbage materials to be gradually guided to the fine cutting notch for cutting.

In foretell kitchen garbage disposer, every cutting tooth is rectangular shape and vertical setting, and the leading edge of every cutting tooth has the blade, and the blade sets up downwards to one side. The oblique downward setting can be the bore that enlarges the lower export of material way between two adjacent cutting teeth for the material falls down more easily, can not cause the jam, can also form the point contact of similar scissors with the blade of cutting knife, compares and just can cut off with line contact can use a small amount of moment.

In the kitchen waste disposer, the rear edge of each cutting tooth is an arc-shaped surface. The rear edge of the cutting tooth is an arc-shaped surface and can be easily separated when the cutting knife is reversed and retreated. Secondly, the sharp-pointed noise can be produced when the first blade of cutting knife is high-speed through cutting tooth periphery face when corotation, and makes the cutting tooth trailing edge into the arcwall face, thereby makes the air current carry out the water conservancy diversion along the arcwall face and lowers and change sharp-pointed noise.

In the kitchen waste disposer, the impeller is arranged on the lower side surface of the cutter head, extends downwards and is close to the bottom of the shell. The discharge of the material at the bottom of the housing is accelerated by means of an impeller, by means of which an agitating effect can be created, enabling the material to be suspended in the water instead of being deposited at the bottom.

In the kitchen waste disposer, the upper outer edge of the impeller can be sheared by the cutting teeth.
