Description

[0001] Food waste disposal assembly having grinding and stirring function [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food garbage disposal assembly, and more particularly, to a food garbage disposal assembly capable of sequentially carrying out drying while simultaneously pulverizing and stirring using one driving motor.

Food waste generated in the process of cooking, etc., when landfilled, causes leachate and causes pollution of soil and water quality. If it is incinerated together with general garbage, it causes dioxin emission in the atmosphere. And a separate policy for collecting and collecting them separately is being implemented.

According to such circumstances, in general households, food waste filtered through a drain hole installed in a drain hole of a sink is collected in a plastic container having a lid, and is collected in a food garbage bag or a food garbage container used in a cavity.

However, it is one of the most unpleasant things to do in kitchen work to empty food waste in the sink because cleaning the wet food waste in the sink bowl is not good and it smells bad and water can fall off the floor during the transfer process. It is often the case that the food waste is cleaned after some gathering of food waste rather than cleaning the drainage passage filter at any time. In addition, not only does it cause poor indoor environment such as odor and hygiene, but also leakage of food waste through the filter basket Which may cause clogging of sewage pipes.

As a method for reducing inconvenience related to the treatment of wet food garbage in the sink, a dehydrator for installing a countertop has been developed and used, which removes water to some extent and empties the food waste before it is emptied.

For example, in the domestic registered utility model No. 0152483, the 'Dust dehydration device attached to the drain hole of the sink bowl' is registered in the domestic registered utility model 0273242 'Drainage water dehydration device of the sink', and the dehydrated food waste of the sink registered in the domestic registered utility model 0181576 Device ', a domestic registered utility model 0308516' 'kitchen garbage dewatering device for sink' ', and' demountable food waste sludge dewatering device 'of domestic registered utility model 0383594.

However, according to the above-described prior art, the following problems are common.

That is, in order to crush or crush various kinds of food wastes into a small size, a high rotation number such as a blender commonly used, for example, a shredding blade rotating at 1,000 rpm to 3,000 rpm is required.

The problem is that in the course of drying food waste that is finely crushed by such crushing blades, the moisture contained in the food waste is evaporated, and the properties of the food waste are changed in the form of solids such as rice cakes and rubber. At this time, the solid material may be pulverized again in a powdery form only by stirring the solid material at a slow rate. The solid material may be converted into a small granule form by rotating at a small number of revolutions, usually 10 rpm to 300 rpm.

In this regard, the food waste is usually crushed using a high-speed rotary blade and then transferred to a separate drying apparatus, where the food waste is dried in a powder form while rotating and stirring in a drying furnace using another motor rotating at a slow speed .

As a result, there is a problem that the size of the whole food garbage disposal apparatus increases or the manufacturing cost increases because a transfer passage for drying food waste is required and a separate drying apparatus is required.

In addition, there is a problem that the food waste is clogged during transportation and the odor due to food waste flows out during transportation.

It is therefore an object of the present invention to provide a food garbage disposal assembly capable of reducing the overall size and simplifying the structure by simultaneously crushing the food waste by high- .

Another object of the present invention is to provide a food garbage disposal assembly in which the pulverization and drying of food garbage is carried out in the same tank without transporting the pulverized food garbage.

Preferably, when separating the filtering cylinder from the crushing / stirring apparatus, the stirring shaft to which the crushing shaft coupled with the second joint and the cutter are coupled to the stirring blade is kept coupled to the bottom of the filtering cylinder .

Preferably, the filtering cylinder comprises: an outer case formed in a cylindrical shape having an open end and formed with a plurality of slots extending in the height direction spaced apart along the circumference; And an inner case which is rotatably overlapped in the outer case and has a plurality of exhaust holes formed in a portion corresponding to the slot, the bottom of the outer case has a predetermined thickness, the upper surface is flat, Receiving grooves are formed.

According to the above configuration, the food waste is crushed by high-speed rotation using one motor and the crushed food waste is stirred by the low-speed rotation at the same time, thereby reducing the overall size of the food waste processing assembly and simplifying the structure And the manufacturing cost can be reduced.

In addition, since the food waste is crushed and then dried in the same filtration tank without being transported to a separate apparatus, there is no problem in that the food waste is not clogged during the transporting process and odors are discharged from the food waste.

Furthermore, since the food waste is agitated while grinding or drying is performed, the grinding efficiency and drying efficiency are improved.

≪ Driving of drive motor 111 >

The rotation of the cover unit 350 actuates a drive switch (not shown) to drive the milling / stirring apparatus 100 and the drying unit 160 according to a predetermined process.

The power is applied to the driving motor 111 and the motor shaft 112 rotates as the driving motor 111 rotates so that the first joint 113 coupled to the end of the motor shaft 112 rotates At the same time, the driving gear 132, which is engaged with the motor shaft 112, rotates.

<Grinding of Food Waste by Cutter 144>

The engagement protrusion 113a of the first joint 113 automatically engages with the engagement protrusion 142a of the second joint 142 and the rotation of the stirring shaft 142a of the second joint 142 is released, The engaging projection 151a of the engaging projection 151 engages with the engaging projection 134a of the spur gear 134. [

In this state, when the first joint 113 rotates, the second joint 142 coupled thereto rotates, and as a result, the cutter 144 coupled to the crushing shaft 141 and the upper end of the crushing shaft 141 is rotated at a high speed .

The food waste remaining in the filter box 200 by the high speed rotation of the cutter 144 is finely crushed. The cutter 144 can rotate at a speed of, for example, 1,000 rpm to 3,000 rpm.

At this time, as described above, since the discharge hole 222 of the inner case 220 is kept away from the slot 212 of the outer case 210, the moisture generated in the pulverizing process is not discharged, ).

&Lt; Agitation by stirring blade 152 >

When the driving gear 132 rotates in accordance with the rotation of the motor shaft 112 as described above, the driving gear 132 is set in advance through the reduction unit 130 including the plurality of reduction gears 133, And finally the spur gear 134 rotates.

As a result, as the stirring shaft 151 coupled with the spur gear 134 rotates, the stirring blade 152 coupled to the stirring shaft 151 rotates at a slow speed. The rotation speed for stirring may be, for example, 10 rpm to 300 rpm.

At this time, the food garbage finely ground by the cutter 144 rotating at a high speed is closely attached to the side wall of the inner case 220 of the filter box 200 by the centrifugal force due to the rotation of the cutter 144, It rotates at a slow speed and removes the food garbage which is adhered to it so that it can be crushed again.

The vertical part of the stirring blade 152 is arranged close to the side wall of the inner case 220 and the side wall itself forms a rugged surface by the discharge hole 222 of the inner case 220, The garbage can be removed.

According to this configuration, the food waste is crushed while the cutter 144 is rotated at a high speed by using the single drive motor 111, and at the same time the stirring blade 152 is rotated at low speed to stir the crushed food waste, The overall size of the processing assembly can be reduced, the structure can be simplified, and the manufacturing cost can be reduced.

In addition, since the food waste is simultaneously stirred while being pulverized, the pulverization efficiency is improved.

<Drying process>

When the pulverization of the food waste by the cutter 144 is completed, power is supplied to the drying unit 130 according to a predetermined process, heat generated in the heater 162 is transferred to the filter box 200, Water is heated to generate steam.

In this process, the cutter 144 rotates at a high speed to generate a vortex in the filter box 200 so that heat is convected, and the stirring blade 151 rotates at a low speed to mix the food wastes, thereby improving the drying efficiency.

According to this configuration, even if the moisture contained in the food waste is evaporated while the food waste is finely pulverized by the cutter 144 and the quality of the food waste changes in the form of a solid such as rice cakes or rubber, 151) rotates at a slow speed to pulverize solids into powder, thereby increasing the grinding efficiency.

In addition, since the food waste is crushed and then dried in the same filtration tank without being transported to a separate apparatus, there is no problem in that the food waste is not clogged during the transporting process and odors are discharged from the food waste.

The water vapor is exhausted to the condensing unit 400 through the exhaust pipe 410 connected to the outside of the sink flange 360 through the space between the cover unit 350 and the sink flange 360.

When the water remaining in the filter box 200 is completely removed through the drying process, the entire process is terminated according to a predetermined process.

The user may open the cover unit 350 and pull out the filter box 200 from the case 300 to dispose of the food waste that has been finely pulverized and dried in the filter box 200. [
