Background Art [2] A waste food Operator is an apparatus that can sanitarily dispose garbage by compressing and heating/drying the garbage thereby removing odor from the garbage.

[3] With a rapid increase of the world population, garbage generated on a daily basis is also increasing rapidly such that millions of tons of garbage all over the world. Since all of the garbage cannot be disposed, most of the garbage is buried in a landfill site, causing the garbage odor problem. The problems associated with the garbage are very severe. For example, salts contained in the buried garbage may cause ground pollution.

[4] To solve these problems, many countries have developed a various waste food Operators. One of them is disclosed in Korean Utility Model Publication No.

1997-0006559, entitled"WASTE FOOD OPERATOR".

[5] However, the waste food Operator has a screw-shaped agitating blade installed in a horizontal direction. Thus, a size of the waste food Operator is very large. When such a garbage disposal is installed in a restaurant, it occupies a large space making it in- convenient to use.

[6] Disclosure of Invention Technical Problem [7] To solve the above problems, the present invention provides a manufacturing Technology of waste food Operator with Rotate Function by Screw, in which a screw- shaped agitating blade for agitating garbage and microorganism-decomposition sawdust is vertically installed such that a large-sized waste food Operator can be installed in a small space.

[29] Best Mode for Carrying Out the Invention [30] Hereinafter, a waste food Operator having a screw rotation-agitation function according to the present invention will be described in detail with reference to the ac- companying drawings.

[31] FIG. 1 is a perspective view of a waste food Operator having a screw rotation- agitation function according to the present invention.

[32] Referring to FIG. 1, the waste food Operator 100 has a shape of a vertically elongated box and includes a plurality of panels 110 to form an outer appearance. The panels 110 include a top panel 112 forming a top external appearance, a bottom panel 116 forming a bottom external appearance, side panels 114 forming a side external appearance, a front panel 117 forming a front external appearance, and a rear panel 118 forming a rear external panel.

[33] The top panel 112 closes a top side of the waste food Operator 100 and is rotatable installed to selectively open an inside of the waste food Operator. The bottom panel 116 forms the bottom external appearance as described above and also supports a load of a plurality of components installed inside the waste food Operator.

[34] The side panels 114 are formed with the same size and allow an insertion of the garbage and a discharge of the microorganism-decomposition sawdust. That is, the side panels 114 include a left side panel 114'forming a left side surface and a right side panel 114"forming a right side surface. A rectangular outlet O is formed at a lower portion of the left side panel 114'and an inlet I is perforated near the center of the right side panel 114".

[35] Accordingly, when the garbage is inserted into the waste food Operator through the inlet I, the garbage is fermented while being agitated with the microorganism-de- composition sawdust, and then is eliminated. The sawdust whose microbial de- composition ability becomes degraded after a predetermined time elapses is discharged through the outlet O.

[36] FIG. 2 is a perspective view illustrating electronic components installed in the waste food Operator having the screw rotation-agitation function according to the present invention, and FIG. 3 is a longitudinal sectional view of a wall surface to which the preferred embodiment of the present invention is applied.

[37] Referring to FIG. 2, a heating wire C is installed in the inside the panels such that the garbage placed into the waste food Operator can be fermented within a short period of time. Since the heat wire C emits heat when a power is supplied thereto, the heat wire C helps the ferment of the garbage.

[38] A heat insulator H is installed in a left side of the heat wire C (see FIG. 3) such that the heat emitted from the heat wire C is transmitted to the panels 110, thereby preventing heat loss. An inner panel 110'is installed in a right side of the heat wire C.

The inner panel 110'is in contact with the heat wire C.

[39] Accordingly, the heat emitted from the heat wire C is not transmitted to the panels 110, but is transmitted to the inner panel 110'. Thus, the inside of the garbage disposal apparatus is maintained at a high temperature without losing heat.

[40] In the inner upper side surrounded by the panels 110, a partition panel (120 in FIG.

2) is provided which has a shape of a rectangular panel whose size corresponds to a cross-sectional area of the inner space of the panels 110. The partition panel 120 partitions the inner space of the waste food Operator into upper and lower spaces. The partition panel 120 is attached to the inner panel 110'in such a state that it is supported by a r-shaped reinforcement member.

[41] Accordingly, when the installation of the partition panel 120 is finished, an electrical component chamber 130 and an eliminating chamber 140 are provided at an upper portion and a lower portion of the partition panel 120, respectively. A plurality of electrical components are installed in the electrical component chamber 130, and the garbage is decontaminated in the eliminating chamber 140. Loads of the plurality of electrical components can be supported by the partition panel 120, which is supported by the reinforcement member S.

[42] A circular through-hole (122 in FIG. 1) is formed in the center of the partition panel 120. The through-hole 122 accommodates one end of a screw-shaped agitating blade 152, which will be described later, and guides a rotation thereof. An upper bearing (132 in FIG. 2) having the same center as the through-hole 122 is installed in an upper side of the through-hole 122, thereby helping the rotation of the screw-shaped agitating blade 152.

[43] Meanwhile, as described above, the plurality of electrical components are installed in the electrical component chamber 130. That is, an agitator motor 134 is installed in an upper side of the upper bearing 132. The agitator motor 134 is connected to an upper portion of the screw-shaped agitating blade 152 and generates a rotating force when a power is applied thereto. Thus, the agitator motor 134 allows the garbage to be agitated within the waste food Operator 100.

[44] A deodorizing unit 136 is installed in a left side with spaced apart from the agitator motor 134. The deodorizing unit 136 eliminates the odor from the eliminating chamber 140 out of the waste food Operator 100. Although not shown, it is preferable that a hole should be formed at a lower portion of the deodorizing unit 136, more particularly at one side of the partition panel 120, such that it is connected with the eliminating chamber 140.

[45] Also, a deodorizing hole 113 is formed at a predetermined portion of the top panel 112 such that the odor introduced from the eliminating chamber 140 to the electrical component chamber 130 can be discharged out of the waste food Operator 100 due to the operation of the deodorizing unit 136.

[46] A heater temperature controller 138 is installed in a right side of the electrical component chamber 130 and controls temperature of the heat wire C. The heater temperature controller 138 is connected to a control box 180, which is attached to an outer surface of the panel 110 and controls the waste food Operator 100. In such a con- figuration, the heater temperature controller 138 maintains an inside temperature of the eliminating chamber 140 to a preset temperature.

[47] An agitator timer 139 is installed in front of the heater temperature controller 138.

The agitator timer 139 is operated by the control box 180. By controlling an operation time of an agitator 150, the agitator timer 139 can prevent an excessive operation of the waste food Operator 100.

[48] FIG. 6 is a longitudinal sectional view of the agitating unit that is installed according to the preferred embodiment of the present invention.

[49] Referring to FIG. 6, the agitator 150 that is a main element is installed in an internal center of the eliminating chamber 140. The agitator 150 includes a screw-shaped agitating blade 152 having an outer surface formed in a spiral shape, and a hollow agitating cylinder 154 for accommodating the screw-shaped agitating blade 152.

[50] The screw-shaped agitating blade 152 rotates to move the garbage upward in such a state that it is installed vertically elongated. As described above, an upper portion of a rotational center shaft 152'passes through the upper bearing 132 and is connected to the agitator motor 134, and a lower portion of the rotational center shaft 152'is inserted into the lower bearing 132'and is supported upward such that it is rotatable.

[51] Also, the screw-shaped agitating blade 152 functions to agitate the garbage. That is, an outer diameter of the screw-shaped agitating blade 152 is formed corresponding to an inner diameter of the agitating cylinder 154. An upward flow is controlled by a flow regulating panel 160 provided at an upper portion, so that the garbage is agitated.

[52] In more detail, in the rotation of the screw-shaped agitating blade 152, the garbage flowing upward is restricted by the inner periphery of the agitating cylinder 154 and is in contact with a bottom of the flow regulating panel 160 such that a strong pressure is applied thereto. Also, the garbage is guided by a flange 162 formed at an outer side of the flow regulating panel 160 and thus is dropped downward. In this manner, the garbage is effectively agitated.

[53] Referring again to FIG. 2, a plurality of cylindrical supporters 142 are installed at a lower portion of the agitating cylinder 154 such that the agitating cylinder 154 is maintained spaced apart from the bottom panel 116. Both ends of each supporter 142 are respectively attached to a lower portion of the agitating cylinder 154 and an upper surface of the bottom panel 116. Accordingly, the supports 142 can support the load of the agitating cylinder 154 and regulate the flow of the garbage.

[54] An inlet shielding panel 144 for shielding an upper portion of the inlet I is attached to a right inner surface of the eliminating chamber 140. The inlet shielding panel 144 interferes a traveling direction of the garbage dropped from the flow regulating panel 160 so as to prevent the garbage from blowing out of the inlet I.

[55] Accordingly, it is preferable that the inlet shielding panel 144 should have a width corresponding to a width of the right side panel 114"so as to completely shield the upper portion of the inlet I. It is apparent that an inlet door 145 can be further provided to selectively shield the inlet I by the rotation of the inlet I.

[56] A sawdust guider 170 is installed in a lower portion of the inlet shielding panel 144.

The sawdust guider 170 guides the garbage and the microorganism-decomposition sawdust, which are introduced through the inlet I, to the center portion of the waste food Operator 100, more particularly to a lower portion of the agitator 150. The sawdust guider 170 is inclined slightly.

[57] Also, like the panels 110, the sawdust guider 170 is configured to emit heat. That is, the sawdust guider 170 includes a first guide plate 172 forming a bottom surface and a second guide plate 174 forming a top surface. The first guide plate 172 and the second guide plate 174 form an outer appearance of the sawdust guider 170.

[58] A heat wire C and a heat insulator H are installed inside the first guide plate 172 and the second guide plate 174. This structure helps the ferment of the garbage.

[59] As described above, the outlet O is formed at a lower left side of the eliminating chamber 140. An outlet door 176 is installed at a portion spaced apart from a right side of the outlet O. When the garbage agitated by the waste food Operator 100 is discharged to the outside, the outlet door 176 selectively rotates to open the inside.

[60] A joint pipe 178 is installed at an outer side of the outlet door 176. The joint pipe 178 is formed by bending a rectangular plate several times. Both ends of the joint pipe 178 are attached to one side of the second guide plate 174 and the outlet O, such that the sawdust can be discharged out of the waste food Operator 100.

[61] Hereinafter, a manufacturing Technology of waste food Operator will be described with reference to FIGs. 1 to 9.

[62] FIG. 5 is an exploded perspective view of components included in the waste food Operator having the screw rotation-agitation function according to the present invention, and FIG. 6 is a longitudinal sectional view of an agitating unit that is installed according to the preferred embodiment of the present invention. FIGs. 7 and 8 are front views of the panels according to the preferred embodiment of the present invention. FIG. 9 is a longitudinal view illustrating a process of inserting garbage and discharging microorganism-decomposition sawdust.

[63] Referring to FIG. 5, a plurality of steel plates are cut and bent to make the panels 110 to form the inner/outer appearances of the waste food Operator 100. (Panel making step) [64] In more detail, the top panel 112, one bottom panel 116, one front panel 117, one rear panel 118, one partition panel 120 and one inlet shielding panel 114 are prepared, and two first guide plates 172 and two side panels 114 are prepared. Of course, the inner panel 110'installed inside each panel 110 is also prepared as many as the number of the panels.

[65] When the panel making step is finished, the bottom panel 116, the side panel 114 and the rear panel 118 are welded with one another to form the outer appearance of the rectangular box whose top and front sides are opened. (Appearance forming step) [66] After the outer appearance is formed in the above manner, the partition panel 120 is attached on the upper portion of the waste food Operator 100 while maintaining a horizontal state with respect to the ground surface to thereby partition the inner space into the electrical component chamber 130 and the eliminating chamber 140, as shown in FIG. 1. (Inside partitioning step).

[67] After the inner space of the waste food Operator is partitioned by the partition panel 120, right/left vibrations of the panels 110 are restricted by the partition panel 120, which is supported upward by the reinforcement member S. Consequently, it is apparent that the installation of the components is easy.

[68] Then, the sawdust guider 170 is installed such that the garbage and the sawdust inserted through the inlet I can be collected in the inner center of the waste food Operator 100, more particularly to the lower portion of the agitator 150. (Guider installing step) [69] The sawdust guider 170 is configured with a plurality of components and is assembled through several processes. That is, the assembling step of the sawdust guider 170 includes the steps of: attaching the first guide plate 172 on the inner wall of the panel 110; installing the heat insulator H on the first guide plate 172; burying the heat wire C in the heat insulator H; and placing and fixing the second guide plate 174 on the heat insulator H. Here, the second guide plate 174 forms the top surface of the sawdust guider 170.

[70] Accordingly, the sawdust guider 170 can increase the inner temperature of the waste food Operator 100 by the heat wire C that generates heat when the power is applied thereto. Also, since the heat loss is prevented by the heat insulator H, it is possible to ferment and eliminate the garbage with a small power consumption.

[71] If the installation of the sawdust guider 170 is finished, the screw-shaped agitating blade 152 for agitating the garbage is inserted into the hollow agitating cylinder 154.

(Blade inserting step) Then, the agitator 150 including the screw-shaped agitating blade 152 and the agitating cylinder 154 is installed in the inner space, which is defined by the panels, in a vertically direction. (Agitator installing step) [72] As shown in FIG. 6, the agitator installing step includes the steps of: respectively inserting both ends of the rotational center shaft 152'into the upper bearing 132 and the lower bearing 132'and regulating their release; connecting the rotational center shaft 152'and the agitator motor 134 such that they are interfaced with each other; installing the supporter 142 in the bottom of the agitator cylinder 154 such that the agitator cylinder 154 is maintained spaced apart from the ground surface; and installing the flow regulating panel 160.

[73] In this manner, the garbage mixed with the sawdust flows repeatedly upward and downward by the rotating force of the agitator motor 134 and the interference of the flow regulating panel 160, so that the garbage is agitated.

[74] After the agitator installing step is finished, the outlet door 176 and the joint pipe 178 are installed such that they rotates at one side of the sawdust guider to allow the sawdust to be discharge to the outside. (Outlet door installing step) The inlet door 145 and the outlet shielding plate 144 are installed such that the garbage and the sawdust are prevented from blowing out of the panels 110. (Inlet shielding step) [75] Then, the heat wire C is attached to the inner side of the panel 110 and the heat wire C is built so that it cannot be exposed. In this manner, the heat loss within the waste food Operator 110 is minimized, and the ferment and elimination effect of the garbage are maximized.

[76] If the heat wire C is built in the inside of the panels 110, the step of making the eliminating chamber 140 is finished. A plurality of electrical components are installed in the upper portion of the partition panel 120, that is, inside the electrical component chamber 130. (Electrical component installing step) The electrical components include the agitator motor 134, the deodorizing unit 136, and the heater temperature controller 138.

[77] If the installation of the electrical components is finished, the inside of the waste food Operator 100 is made completely. The electrical component chamber 130 and the eliminating chamber 140 are completely shielded by installing the top panel 112 and the front panel 117 on the top and front sides of the waste food Operator 100. (Internal shielding step) [78] Then, the control box 180 is attached on the front left upper portion of the panel 110 (Control box attaching step) and is electrically connected to the electrical components.

Thus, the waste food Operator 100 is made completed.

[79] Hereinafter, the operation of the waste food Operator according to the present invention will be described with reference to arrows indicated in FIGs. 4 to 9.

[80] As shown in FIG. 9, the inlet I is opened by rotating the inlet door 145 in such a state that the power is supplied to the waste food Operator 100. The garbage and the sawdust are inserted into the waste food Operator.

[81] The garbage and the sawdust inserted through the inlet I are slid by the sawdust guider 170, such that they are collected in the center of the waste food Operator, more particularly in the lower portion of the agitator 150.

[82] At this point, the control box 180 is manipulated to drive the agitator motor 134, the heater temperature controller 138 and the deodorizing unit, which are installed in the electrical component chamber 130.

[83] As shown in FIG. 4, due to the operation of the agitator motor 134, the screw- shaped agitating blade 152 is rotated about the rotational center shaft 152'such that the garbage and the sawdust are agitated with each other. Due to the operation of the heater temperature controller 138, the inside of the waste food Operator is heated such that the garbage is fermented rapidly. Due to the deodorizing unit 136, the odor in the waste food Operator 100 is discharged through the inside of the electrical component chamber 130 and the deodorizing hole 113 to the outside.

[84] In the process of agitating the garbage and the sawdust, the top surface in the lower portion of the screw-shaped agitating blade 152 moves the garbage and sawdust, which are inserted between the supporters 42, upward along the inside of the agitator cylinder 154. Since the upward movement of the garbage and the sawdust is regulated by the bottom surface of the flow regulating panel 160, the garbage and the sawdust again move downward. By repeating this process, the garbage and the sawdust are agitated.

[85] If the garbage is fermented sufficiently due to the sawdust through the above process, the garbage is gradually eliminated as the time elapses. The sawdust whose microbial decomposition ability is degraded by the longtime use is discharged through the outlet O by opening the outlet door 176. Accordingly, the process of the garbage using the waste food Operator is completed.

[86] It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.

[87] Industrial Applicability [88] According to the present invention, a volume of the waste food Operator can be minimized by vertically installing the agitator, thereby increasing the usage convenience.

[89] Also, even when an installation space for the waste food Operator is small, the waste food Operator can be installed and operated, thereby increasing the space utilization.

[90] Further, since the garbage is eliminated, it is very sanitary.
