Grinding structure in kitchen garbage processor

Technical Field

The invention belongs to the technical field of kitchen waste treatment, and relates to a grinding structure in a kitchen waste processor.

Background

The kitchen garbage disposer is relatively common auxiliary equipment in modern kitchens, is arranged at the bottom of a water tank, is internally provided with a grinding structure, and kitchen garbage is directly flushed into the kitchen garbage disposer from the water tank to be crushed, ground and the like and then discharged into a sewer. For example, patent application number 201310197438.9 discloses a garbage disposer, it includes the shell, be equipped with the water leakage mouth on the shell, be equipped with grinding chamber in the shell, grinding mechanism and drive arrangement and grinding chamber, grinding mechanism and drive arrangement constitute the garbage disposer main part, grinding mechanism is located the grinding chamber, grinding mechanism mainly comprises the impact hammer, the feeding blade, the side blade, grinding plate and auxiliary cutterhead, auxiliary cutterhead fixed mounting is in the grinding chamber and with grinding plate parallel arrangement, the side blade is equipped with straight sword and external horizontal sword, auxiliary cutterhead is equipped with built-in horizontal auxiliary tooth, horizontal sword on the side blade is located the top of grinding tooth on the grinding plate, auxiliary tooth on the auxiliary cutterhead is located the below of grinding tooth. When the garbage is used, garbage is discharged into a grinding chamber together with water, firstly, the garbage is crashed in the grinding chamber through the impact hammer, then is cut and crashed by the straight cutter, then is subjected to primary grinding and cutting by the transverse cutter and the grinding teeth on the grinding disc, and finally is subjected to secondary grinding and cutting by the grinding teeth on the grinding disc and the horizontal auxiliary teeth on the auxiliary cutter disc. Through the structure, the obtained crushed particles are smaller, and the discharge becomes simpler, so that the sewer is not blocked.

However, in practice, kitchen waste contains both hard residues such as bones and soft long fiber residues such as vegetables and peel, and hard residues such as bones and the like are well treated after the primary grinding cutting by impact hammers, the horizontal blades and the grinding teeth on the grinding disc and the secondary grinding cutting by the grinding teeth and the horizontal auxiliary teeth on the auxiliary cutter disc, but the soft long fiber residues are hard to be ground by the upper grinding mechanism consisting of the horizontal blades and the grinding teeth on the grinding disc and the lower grinding mechanism consisting of the grinding teeth and the auxiliary grinding teeth on the auxiliary cutter disc because of being soft and slender, and thus soft long fiber residues are accumulated in the machine for a long time to cause internal blockage and blockage of the machine.

Disclosure of Invention

The invention aims to solve the problems in the prior art, provides a grinding structure in a kitchen waste processor, and solves the problem that the inside of the kitchen waste processor is easy to be blocked due to incomplete fiber waste treatment.

The aim of the invention can be achieved by the following technical scheme:

the utility model provides a grinding structure in kitchen garbage treater, includes grinding ring, lower grinding ring and rotates the grinding disc subassembly that sets up between the two, lower grinding ring has a plurality of lower grinding teeth along circumference, and grinding disc subassembly middle part border has and is located lower grinding teeth top and cooperate the well grinding teeth that forms grinding mechanism down with it, its characterized in that, each lower grinding tooth distributes in the inboard of grinding ring down, grinding disc subassembly lower part border has the cutting part that sets up along the level, and the cutting part is located the inboard of each lower grinding tooth, and the cutting part flushes or roughly flushes with lower grinding tooth.

The grinding structure is arranged in the shell of the kitchen garbage processor, wherein the upper grinding ring and the lower grinding ring are fixed in the shell and are separated by the rubber pressing ring, an output shaft of a motor arranged in the shell upwards penetrates through the grinding disc assembly and is fixed in the circumferential direction, and therefore the grinding disc assembly is driven to rotate relative to the upper grinding ring and the lower grinding ring when the output shaft of the motor rotates. The kitchen garbage processor is connected below the water tank water outlet, kitchen garbage is flushed into the shell of the kitchen garbage processor when the water tank is drained and falls into an area formed by the inner side of the upper grinding ring and the upper side of the grinding disc assembly, the motor drives the lower cutting disc and the grinding disc to rotate at a high speed, and the kitchen garbage is gradually thrown to the inner wall position of the upper grinding ring and is crushed under the action of centrifugal force. Then, the kitchen waste flows downwards along with the water, and is ground in the horizontal direction by a lower grinding mechanism consisting of the lower side surface of each middle grinding tooth and the upper side surface of each lower grinding tooth.

The lower grinding mechanism has a good grinding treatment effect on harder kitchen wastes, but fibers cannot be well treated by the lower grinding mechanism because of being thinner and softer. Further, since the lower edge of the grinding disc assembly is provided with the cutting part which is horizontally arranged, the cutting part is positioned at the inner side of each lower grinding tooth and is flush or approximately flush with the lower grinding tooth, during the rotation of the grinding disc assembly, kitchen waste of fibers can be continuously extruded between the cutting part and each lower grinding tooth, and then during the subsequent rotation of the grinding disc assembly relative to the lower grinding ring, the kitchen waste of fibers is continuously pulled and fully cut by the cooperation of the cutting part and each lower grinding tooth, so that the machine internal blockage possibly caused by incomplete treatment of the kitchen waste of fibers can be avoided, and the use reliability is improved.
