BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grinding furnace of a food processor, and more particularly, to a grinding furnace for grinding a food waste by improving the shape of a grinding screw mounted on the grinding furnace, To a grinding furnace of a food processor.

There are methods of treating food waste such as a fermentation treatment method, an incineration treatment method, a method of recycling to feed and fertilizer (compost), a method of landfilling into soil, etc. However, the above- Such as odor or discomfort due to collection, transportation or storage, and environmental pollution. Accordingly, there is an urgent need for a method that can reduce environmental pollution caused by food waste, and can be recycled and used.

Generally, a device for treating food waste connected to a household sink can remove moisture from food waste through a series of processes such as dehydration, cutting and drying, and reduce the volume of the food waste, thereby greatly reducing the amount of the waste.

Conventionally, a device for treating food garbage includes a feeding port into which food waste is fed, a dehydration / cutting section for cutting and chopping the food waste while compressing and dewatering the food waste, a feeding section for moving the dehydrated and cut food waste to one side, A drying unit for drying the food waste by removing water by high temperature while uniformly turning over and dispersing the food waste dewatered and cut by the rotating blades, and a discharge tray for discharging and storing dried food waste.

In recent years, free standing food processing machines that can be installed freely in the home as well as in a sink type have been widely used. The free standing type food processing machine is also used in the same manner as in the case of a sink type, And so on.

The stirring, pulverizing and drying processes are mainly performed in a drying furnace of a food processor. In particular, in the vertical drying furnace, when the stirring and grinding processes are performed, there is a problem that the food is not circulated vertically in the drying furnace. That is, stirring is performed only by the height of the blade of the rotating screw, which is responsible for stirring / crushing, in the drying furnace, so that the introduced foodstuffs can not be finely crushed as a whole. In addition, when a light material such as starch or the like is injected, it may not be well pulverized and may be aggregated into agglomerates, resulting in an excessive load on the rotating screw and the motor.

Meanwhile. In recent years, free-stand type food processing machines have been widely used among consumers because they are not installed in a conventional sink, but the complaint that food waste is left inside the drying chamber without being crushed finely among consumers This is because of the tendency that the satisfaction of the consumers is lowered, so it needs to be improved.

In order to solve the above-mentioned problems, the present invention is characterized in that a shape of a pulverizing screw is formed into a spiral shape in a radial direction around a vertical rotation axis, and a central portion of an inner bottom surface of a pulverizing drying furnace corresponding to the pulverizing screw is constituted by a convex spherical structure, And an object of the present invention is to provide a grinding furnace of a food processor that increases efficiency.

According to another aspect of the present invention, there is provided a pulverizing furnace for a garbage disposal apparatus, including a housing accommodating food waste, and a pulverizing screw rotatably coupled to the housing, Is characterized in that the center of the crush plate is a spherical shape convex upward.

The pulverizing screw has a concave shape on the lower surface corresponding to the crushing plate, and the food waste can be crushed by interaction with the crushing plate.

The pulverizing screw may include a rotating shaft disposed vertically in the housing and a rotating blade extending in a spiral shape from a center of the rotating shaft.

The rotary vane may have a structure continuously extending from one side of the rotary shaft to the other side of the rotary shaft.

The rotary vane may be formed with a circumferential hole formed radially between the rotary vane and the rotary shaft.

One or more crushing grooves may be formed at a lower end of the rotary vane and a crushing projection may be provided on the crushing plate to correspond to a locus formed by the crushing groove when the rotary vane is driven.

An edge of the crush plate may be provided with a discharge hole through which the crushed garbage is discharged in the housing.

The pulverizing furnace of the food processor may further include a feed screw rotatably coupled to the housing, wherein the pulverizing screw has the same rotation center line as the feed screw.

Wherein the housing comprises an upper housing in which the conveying screw is disposed and a lower housing in which the pulverizing screw is disposed, the food waste stirred by the conveying screw by the conveying hole formed in the crushing plate of the upper housing, Lt; / RTI >

In the pulverizing furnace of the food processor of the present invention as described above, the food waste introduced by the interaction between the pulverizing groove formed in the rotary blade of the pulverizing screw and the pulverizing protrusion formed on the pulverizing plate can be finely pulverized. In this case, since the central portion of the crushing plate takes the shape of a spherical surface protruding upward, the contents can naturally move to the edge of the crushing plate at the same time as the crushing, thereby facilitating the discharge to the outside. In addition, the food garbage introduced through the rotation of the rotary vanes in the forward and reverse directions is uniformly dispersed, thereby preventing a phenomenon of aggregation on one side.

These and other objects, features and other advantages of the present invention will become more apparent by describing in detail preferred embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a pulverizer of a food processor according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The pulverizing screw 130 is rotatably coupled to the housing 110. [ The rotation center line 101 forms a rotation center of the conveying screw 120 and the pulverizing screw 130 as an imaginary line passing through the center axis of the housing 110.

The housing 110 includes an upper housing 111 in which the conveying screws 120 are disposed and a lower housing 116 in which the pulverizing screws 130 are disposed. 112 to move the food waste agitated by the feed screw 120 to the lower housing 116. The conveying screw 120 includes a first rotating body 121 and a stirring blade 122 extending in the radial direction from the first rotating body 121. The stirring vane 122 may be tapered so as to be gradually tapered away from the first rotating body 121. Under the above-described structure, the stirring vane 122 flows through the inlet 102 formed in the upper housing 111 The food waste can naturally flow into the transfer hole 112 while preventing the food waste from collecting in the center of the upper housing 111.

The pulverizing screw 130 includes a second rotating shaft 132 disposed vertically in the housing 110, a rotating blade 133 extending spirally from the center of the second rotating shaft 132, and a second rotating shaft 132 And a connecting rod 131 extending from an end of the connecting rod. The fastening rod 131 is inserted into the first rotating body 121 of the feed screw 120 so that it serves as a guide for driving the pulverizing screw 130 and the feed screw 120 about the axis of rotation 101 . Here, since the pulverizing screw 130 and the feed screw 120 can rotate independently of each other, the coupling surfaces of the coupling rod 131 and the screws 120 and 130 can be coupled using bearings or the like.

The rotary vane 133 may be continuous from the outer peripheral surface of the second rotary shaft 132 to the outer peripheral surface of the second rotary shaft 132 without interruption. That is, it can be realized as a spiral wound around the second rotating shaft 132.

A circumferential hole 134 is formed in the rotary vane 133 between the first rotary shaft 132 and the second rotary shaft 132 in the radial direction. The avoidance hole 134 may include a first escape hole 134a and a second escape hole 134b that maintain a constant distance from the rotation of the pulverizing screw 130. The excessive force of the food waste may cause the rotating blade 133, the driving power may be excessively consumed. Therefore, in order to prevent such a problem, a certain portion of the food may be passed through.

One or more crushing grooves 136 are formed at the lower end of the rotary vane 133 and the crushing plate 136 of the lower housing 116 is rotated in a direction corresponding to the locus of the crushing groove 136 when the rotary vane 133 is driven 119 are formed with arc-shaped crushing protrusions 118. The crushing groove 136 includes a first crushing groove 136a and a second crushing groove 136b which are formed in order from the outer circumferential surface of the rotary vane 133, The crushing projections 118a and the second crushing projections 118b are formed.

At the edge of the crush plate 119 of the lower housing 116, a discharge hole 117 through which the crushed food waste is discharged in the housing 110 is provided.

Hereinafter, the grinding action due to the interaction between the rotary vane 133 and the crush plate 119 of the lower housing 116 will be described with reference to Figs. 4 to 6. Fig. The crushing plate 119 of the lower housing 116 in which the crushing screw 130 is located has a spherical shape whose center is convex upward and the crushing screw 130 is connected to the crushing protrusion 118 formed on the crushing plate 119, It is possible to finely crush the food waste introduced into the food waste.

The first crushing groove 136a forms a first locus 141 on the crushing plate 119 and the second crushing groove 136b is formed on the crushing plate 119 when the crushing screw 130 is rotationally driven Thereby forming a second locus 142. That is, the first crushing protrusion 118a is located on the path formed by the first locus 141 and the second crushing protrusion 118b is located on the path formed by the second locus 142, 130, the crushing protrusion 118 is rotationally driven into the crushing groove 136. The trajectories 141 and 142 form concentric circles having different radii.

According to the present invention, the upward and downward movement of the food waste accommodated in the lower housing 116 is controlled according to the rotating direction of the pulverizing screw 130. Referring to FIGS. 3 and 6, the following will be described. When the pulverizing screw 130 is viewed from the top, the food waste pushed down from the lower surface of the lower housing 116 due to the shape of the rotary vane 133 in the case of the forward rotation 130 rotating in the clockwise direction, In the case of the counterclockwise rotation (104), the predetermined food garbage dump on the lower housing (116) is pushed downward to be flattened so that the biasing of the food garbage does not occur as a whole . Herein, the forward direction or the reverse direction may vary according to the shape of the rotary vane 133, which is considered to be merely a limitation for convenience of explanation in the present invention.

Hereinafter, the operation of the crushing furnace 100 according to the present invention will be described with reference to Figs. 1 to 6 again. First, the food waste is put in an appropriate amount through the inlet 102 of the upper housing 111 along with the rotation of the feed screw 120. The food waste contained in the upper housing 111 falls freely into the lower housing 116 through the feed hole 112 in accordance with the rotation of the stirring vane 122. The pulverizing screw 130 of the lower housing 116 allows the upper and lower parts of the grinding water to agitate the receptacle by rotational driving along the forward or reverse direction to prevent the aggregation of food waste. The grinding grooves 136 formed in the rotary vane 133 enable the grinding grooves 136 to finely grind the food by the interaction with the grinding protrusions 118 formed in the spherical grinding plate 119 during the rotation driving of the grinding screw 130 . Thereafter, the pulverized food waste flows smoothly into the discharge hole 117 formed at the edge of the crushing plate 119, so that the food waste can be discharged. A separate opening / closing device (not shown) may be provided at the lower end of the discharge hole 117, and the discharge speed may be adjusted by adjusting the opening / closing device.

As described above, according to the present invention, the food waste introduced by the interaction between the crushing groove formed in the rotary blade of the crushing screw and the crushing protrusion formed on the crushing plate can finely crush the food waste. In this case, since the central portion of the crushing plate takes the shape of a spherical surface protruding upward, the contents can naturally move to the edge of the crushing plate at the same time as the crushing, thereby facilitating the discharge to the outside.

Although the preferred embodiments of the present invention have been described, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that numerous modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims. And equivalents should also be considered to be within the scope of the present invention.
