{Food Waste Mixing Apparatus}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food waste stirring apparatus, and more particularly, to a food waste stirring apparatus for asymmetrically configuring a shape of a stirring blade disposed in an stirring tank into which food waste is introduced, To an agitating device.

Generally, a certain amount of food waste is discharged every day from households or restaurants, and such food waste is disposed of only after the water has been filtered through a simple screen. This conventional food garbage disposal method increases the quantity of food garbage, and if food garbage is not frequently discarded, odor is generated to pollute the surrounding air.

It is urgently required to develop a household food waste disposer capable of solving such problems in order to effectively suppress the occurrence of food waste and to recycle it. In general, 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. On the other hand, development of freestanding type disposer which can be used as a portable type rather than a type installed in a sink is also diversified, and an improvement work on the shape of the stirring wing is performed in order to improve the stirring / . In addition, it is also necessary to improve the grinding efficiency by the interaction between the inner surface of the agitating cylinder where the agitating blade is seated and the agitating blade.

Conventionally, during the process of stirring the food using the stirring blades in the stirring bar, the food moves gradually toward the edge side of the stirring bar, and as it rotates, it is gathered in a spherical shape and becomes larger, so that the stirring blades are no longer able to perform the stirring operation . In such a state, in the case of the food processor type in which the operation is delayed in the food processing apparatus following the stirring, crushing and drying, or in which the crushing must be performed in the form of powder, the crushing motor is overloaded to cause a failure.

In order to solve the above-mentioned problems, the present invention is characterized in that, in order to solve the above-mentioned problems, the present invention is characterized in that a shape of a stirring blade arranged in an agitating cylinder for rotational driving is formed in an asymmetrical shape, Which is capable of increasing the stirring performance of the food waste.

In order to achieve the above object, the present invention provides a food waste stirring apparatus comprising: an agitating barrel into which food waste is introduced and agitated; a stirring vane rotatably mounted in the agitating barrel; And a blade driving motor connected to the rotating part to provide rotational power to the stirring blade, wherein the stirring blade has a rotating part coupled to a lower center of the stirring barrel, a rotating part extending from one side of the rotating part, And a second blade extending from the other side of the rotating portion and maintaining an inner side surface of the stirring tube and a second moving width narrower than the first moving width, And an arch portion protruding upward.

The second blade may be extended from the rotation part with a predetermined curvature in a clockwise or counterclockwise direction.

The pulverizing rib is provided at an inner edge of the stirring bar to have a predetermined thickness and the pulverizing rib is capable of pulverizing and stirring the food waste in the stirring bar by interaction with the first blade and the second blade.

The pulverizing ribs may be formed by projecting 'L' on the side surface and the bottom surface of the stirring barrel.

Wherein the crushing protrusions are formed on the lower surface of the stirring barrel and the crushing protrusions interfere with the first stirring groove formed in the arch portion or the second stirring groove formed in the lower end of the second blade, Stirring can be carried out.

The food waste stirring apparatus may further include a discharge device disposed at a lower portion of the stirring bar, wherein the discharge device includes a main drive gear having a discharge port, an auxiliary drive gear for transmitting power to the main drive gear, And the discharge port corresponds to the discharge groove formed in the lower surface of the stirring barrel, so that discharge of the food wastes can be interrupted.

The above-described food waste stirring apparatus of the present invention prevents the food waste introduced into the stirring tank from being biased toward one side when the stirring blade having the asymmetrically configured blade rotates in the forward or reverse direction in the stirring tank . The stirring wing allows the food waste to be crushed into a small shape by the interaction with the crushing ribs and the crushing protrusions formed on the inner surface of the stirring bar, thereby improving the drying efficiency when the drying process is simultaneously performed.

In addition, since the load applied to the motor for driving the stirring blades is reduced due to the agglomeration prevention effect of the stirring blade by the present invention, the probability of occurrence of a failure is lowered.

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. Hereinafter, a food waste stirring apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The overall structure of the food waste stirring apparatus 100 will be described with reference to Figs. 1 to 4. Fig. The food waste stirring apparatus 100 includes an agitation barrel 110 into which food waste is introduced and agitated, a stirring vane 120 rotatably mounted in the agitation barrel 110, A stirring blade 110 connected to the agitating vane 120 to provide a rotating power to the agitating vane 120 and a discharge driving motor 140 connected to the agitating vane 120 to discharge the dried food waste in the agitating cylinder 110, And a discharge device 130 for opening and closing the discharge pipe 115.

The stirring barrel 110 includes a hollow cylindrical body 111 having an opening 110a formed at an upper end thereof, a coupling hole 112 formed at the center of the lower end of the body 111, a crushing rib 112 protruding from the side surface of the body 111 A crushing protrusion 114 formed at a predetermined height at the lower end of the body 111 and a discharge hole 115 formed through the lower end of the body 111. The pulverizing ribs 113 may protrude from the side surface and the bottom surface of the agitating cylinder 110 by 'L'.

The stirring blade 120 includes a rotation part 121 coupled to the coupling hole 112 of the stirring bar 110, a first blade 122 extending from one side of the rotation part 121, and a second blade 122 extending from the other side of the rotation part 121 And a second blade 125 which is extended. Here, the end of the first blade 122 is characterized by being relatively distant from the inner surface of the body 111 as compared with the end of the second blade 125. By this structure, the foodstuff flowing inside the body 111 is stirred through different moving widths, so that an environment can be smoothly mixed. 2, a first moving width 117 corresponding to a distance between the end of the first blade 122 and the inner surface of the body 111 during the rotation of the stirring vane 120, And a second moving width 118 corresponding to the distance between the end of the first body 111 and the inner surface of the body 111 is formed. Here, the first moving width 117 is formed to be wider than the second moving width 118, so that the moving food waste can be agitated at various sizes.

The discharge device 130 includes a main drive gear 131 that directly opens and closes the discharge hole 115 of the agitation cylinder 110, an auxiliary drive gear 133 that meshes with the main drive gear 131 and transmits power, And a discharge drive motor 134 coupled to the auxiliary drive gear 133 and generating power. The main driving gear 131 has a serrated periodic gear 131a formed on the outer circumferential surface thereof and a serrated auxiliary gear 133a formed on the outer circumferential surface of the auxiliary driving gear 133 and engaged with each other. The main drive gear 131 has a discharge port 132 whose shape corresponds to the discharge hole 115. The discharge port 132 is located below the discharge hole 115 in accordance with the rotation of the main drive gear 131 The discharge of the food waste in the stirring bar 110 is determined.

The wing driving motor 140 is coupled to the rotation part 121 of the stirring vane 120 through the coupling hole 112 formed at the center thereof. That is, the stirring vane 120 can be rotated by the vane driving motor 140 and the stirring vane 120 can be controlled by adjusting the power applied to the vane driving motor 140 by using a separate control device (not shown) Can be controlled.

Hereinafter, the stirring vane 120, which is a component of the present invention, will be described with reference to Figs. 5 to 7. Fig. The rotating portion 121 of the stirring vane 120 is formed with a through hole 121a through which the fastening hole 141 of the vane driving motor 140 is coupled. The first blade 122 is composed of a rectilinear section 123 extending in a radial direction from one side of the rotation section 121 and an arcuate section 124 convex upward from the rectilinear section 123. In the process of forming the arch portion 124, a first agitating groove 128 is formed. The second blade 125 has an inclined plate 126 extending in the radial direction from the other side of the rotation part 121 and a second stirring groove 127 formed at the lower end of the inclined plate 126.

The agitating grooves 128 and 127 formed in the agitating blade 120 all perform a stirring operation of food and food but have a structure in which the first agitating grooves 128 are higher than the second agitating grooves 127 from the bottom of the body 111 And when the food is stirred through the first stirring groove 128, a relatively large mass of food flows. On the other hand, the second agitating groove 127 allows a large agglomerate of food to be divided into small pieces through the first agitating grooves 128.

In the present invention, the second blades 125 can be extended from the rotating part 121 with a certain curvature so that the food in the stirring bar 110 can be mixed evenly. That is, the inclined plate 126 is formed to be bent in one direction in the process of extending from the rotation unit 121. In the embodiment of the present invention, for example, the inclined plate 126 is curved in a counterclockwise direction when viewed from above.

When the direction of rotation of the stirring vane 120 is the same as the direction of bending of the inclined plate 126 in the above structure, the stirring vane 120 serves to gather the food in the stirring cylinder 110 inward. That is, if the stirring vane 120 rotates in the counterclockwise direction, the food is gradually collected toward the rotating portion 121 side.

On the other hand, if the rotating direction of the stirring vane 120 is opposite to the bending direction of the inclined plate 126, the stirring vane 120 acts to disperse the food in the stirring cylinder 110 outwardly. That is, if the stirring vane 120 rotates in the clockwise direction, the food is gradually dispersed toward the outer peripheral side of the stirring bar 110.

Hereinafter, the agitating action of the food waste using the food waste stirring apparatus 100 according to the present invention will be described with reference to FIGS. 1 to 7. FIG.

After the food is put into the stirring bar 110, the wing driving motor 140 is operated to rotate the stirring wing 120 in the forward or reverse direction. Here, the forward direction can be arbitrarily determined depending on the situation, but in the present invention, the forward direction can be defined as the same direction as the counterclockwise direction in which the inclined plate 126 is bent.

When the stirring blade 120 rotates in the normal direction first, the food moves along the second blade 125 and moves toward the rotating portion 121. In this process, the first stirring groove 128 of the first blade 122 And the second agitating grooves 127 of the second blade 125 make the food stir well by the interaction with the crushing protrusions 114. Here, the second agitating groove 127 functions to finely stir and crush the food having passed through the first agitating groove 128 of the first blade 122.

When the stirring blade 120 rotates in the opposite direction, the food moves to the inner peripheral surface side of the stirring barrel 110 along the second blade 125. The food moved to the bottom edge side of the stirring barrel 110 flows into the first and second moving widths 117 and 118 and stirring is caused by the interaction between the ends of the blades 122 and 125 and the pulverizing ribs 113. Here, since the dimension of the second movement width 118 is smaller than the dimension of the first movement width 117, the food is more finely disintegrated when it is passed over the second movement width 118.

The present invention is characterized in that a large mass of food is divided through the first agitating groove 128 formed in the arch portion 124 of the first blade 122 regardless of the rotational direction of the agitating blade 120, Through the second agitating groove 127 of the second agitating member. As a result, the first blades 122 and the second blades 125 are formed asymmetrically with respect to the rotating portion 121 to perform rotational driving, so that food is not agglomerated in the stirring barrel 110, .

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.
