[29] As shown in Fig. 1, a trash container 100 in accordance with an embodiment of the present invention includes an outer container 110 and a solar cell 130 installed on the upper surface of the outer container 110. 20 [30] The aforementioned outer container 110 may be implemented in various forms such as a rectangular parallelepiped shape, cylindrical shape, etc. and may be made of materials such as metals, alloys, plastics, glass and others. [31] Further, the outer container 110 has at least one or more a trash inlet 113 into which trash is put. The trash inlet 113 may be implemented in various 25 shapes such as circular, oval, square, etc. The position and size of the trash inlet 113 may be modified in a diversity type. 6 [32] The solar cell 133 installed on the upper surface of the outer container 110 is a device to convert light energy into electrical energy, which may be implemented in various forms such as a panel shape, curved shape and so on and may be installed on even the side surfaces, as well as the upper surface. 5 [33] On the other hand, the outer container 110 includes a protective cover 133 for protecting the solar cell 130 from an external shock and contamination. The protective cover 133 may be implemented in various forms such as a flat shape, round arch shape, etc. and may be made of material such as polycarbonate resins, acrylic resins, fiber-reinforced plastics, or the like. 10 [34] Also, the outer container 110 includes a discharge outlet 115, and the discharge outlet 115 is used as a door for taking out a trash bag (for example, a pay-per trash bag), an inner container, and others and may be implemented in different sizes and shapes. [35] Further, the outer container 110 includes a display unit 117 through which 15 information such as the level of trash, the compression driving, a failure, etc. is provided to the user. [36] Fig. 2 illustrates an exemplary inner side surface of a trash container in accordance with an embodiment of the present invention. [37] As shown in Fig. 2, the trash container 100 further includes an inner 20 container 120 and a compression module 140 that is composed of a driving source such as a motor 141 which is fixedly disposed in the inside of the outer container 110, a pair of screws 142 which is dynamically connected to the motor 141 to move up and down and a compression plate 143 installed in the bottom of the pair of screws for a trash compression. 25 [38] Here, the motor 141 is driven by electric energy to supply electric power. It is preferred that the motor is fixedly disposed on a central stationary plate 144 7 which is fixedly installed in the outer container 110. [39] In addition, the inner container 120 is disposed inside the outer container 110 with a trash bag (e.g., a pay-per trash bag) being covered, which may be implemented in various forms such as cylindrical, square, etc. and may be made 5 of materials such as metals, alloys, plastic, glass, etc. [40] Fig. 3 and Fig. 4 a compression module applied to the present invention, and more specifically, Fig. 3 shows a view in which the compression module is in an original position, and Fig. 4 shows a view in which the compression module is lowered for compression. 10 [41] As shown in Figs. 3 and 4, the motor 141 is fixedly disposed on a central stationary plate 144, and a driving shaft gear 145 is formed on a driving shaft coupled to the motor 141 and rotates in forward and reverse directions with the rotation of the motor 141. [42] Further, the pair of screws 142, which is dynamically connected to the 15 motor the motor 141 to move up and down, is installed perpendicular to the central stationary plate 144, and screw gears 146 are engaged with the driving shaft gear 145 to rotate in forward and reverse directions and is screw-coupled to the screws 141. That is, each of the screw gears 146 has a female screw formed inside thereof which is coupled to each of the screws. 20 [43] Though a pair of screws is shown in order to facilitate the description of the present invention with reference to the drawings, the number of the screw are not limited thereto, and it will be obvious that two or more screws may be employed. When using three or more screws, it is also obvious that a configuration coupled to the screws may be differently changed in line with the 25 screws. [44] When the aforementioned motor 141 is driven in the forward direction by 8 supplying with electrical energy under the control of a control unit (not shown), the screw gears 146 that are engaged with the driving shaft gear 145 is driven in the reverse direction in response to the forward rotation of the driving shaft gear 145 formed on the driving shaft, and the female screws formed inside the screw 5 gears 146 are rotated with the reverse rotation of the screw gears 146 to lower the screws 142. Accordingly, the compression plate 143 installed in the bottom of the screws 142 compresses the trash by pushing in accordance with the lowering of the screws 142. [45] Further, when motor 141 is rotated in a reverse direction under the control 10 of the control unit (not shown), the screw gears 146 that are engaged with the driving shaft gear 145 is forwardly rotated with the reverse rotation of the driving shaft gear 145 formed on the driving shaft, and the female screws formed inside the screw gears 146 are rotated with the forward rotation of the screw gears 146 to raise the screws 142. Accordingly, the compression plate 143 installed in the 15 bottom of the screws 142 is returns the original position with the rising of the screws 142. [46] As described above, with the embodiment of the invention, a pair of screws 142 composed of the compression module is used to compress the trash, and a balanced force can be transmitted to the compression plate 143 more than 20 when using a single screw by the use of the pair of screws 142, thereby accomplishing the stable compression of the trash. [47] Further, the use of the pair of the screw 142 can prevent the slap phenomenon between gears occurred when using a single screw. [48] On the other hand, the compression plate 143 is installed on the bottom of 25 the pair of screws 142 to compress the trash. The compression plate includes a first compression plate 143a which is fixedly installed on the bottom of the pair of 9 screws 142 and has an hole formed in the center thereof and a second compression plate 143b which is connected at a distance to the bottom of the first compression plate 143a and integrally moves along with the first compression plate 143a to compress the trash by coming in direct contact with the trash piled 5 up in the inner container 120 and pushing the trash. [49] In this case, the second compression plate 143b is preferably connected to the first compression plate 143a so that the distance to the first compression plate 143a is variable. With the compression of the trash, the second compressor 143b may become close to the first compression plate 143a. 10 [50] On the other hand, the trash container 100 in accordance with the present invention includes a force detection module 150 to detect force over a certain threshold exerted to the compression plate 143. [51] Fig. 5 and Fig. 6 shows schematically a configuration of a force detection module applied to the present invention. Fig. 5 shows a view of the force 15 detection module when the compression is not performed and Fig. 6 shows a view of the force detection module when the compression is performed. [52] The force detection module 150 applied to the present invention includes a switch 151, a protrusion 153, and a leaf spring 155. [53] Here, the switch 151 is arranged at the top of the center of the hole 20 formed in the first compression plate 143a. When the switch 151 is pressed by the leaf spring 155 that is bent with the compression of the trash, and the switch 151 transmits a detection signal to a control unit (not shown). [54] As described above, upon receiving the detection signal transmitted from the switch 151 of the force detection module, the control unit (not shown) controls 25 the deriving of the motor 141 to terminate the lowering compression and raise the screw 142 so that the compression plate 143 returns to the original position. 10 [55] The protrusion 153 is protruded toward the first compression plate 143a at the center of the second compression plate 143b. If the second compression plate 143b is raised by the reaction corresponding to the compression of the trash, the protrusion 153 pushes up the leaf spring 155 from below, thereby bending the 5 leaf spring 155 upwardly. [56] The leaf spring 155 is disposed above the protrusion 153 between the first compression plate 143a and the second compression plate 143b. It is preferable that the leaf spring 155 is arranged so that the distance between the first compression plate 143a and the second compression plate 143b is varied 10 through the use of a connecting member 157. [57] As the second compression plate 143b rises by the reaction corresponding to the compression of the trash, the leaf spring 155 is bent to press the switch 151 by the movement of the protrusion 153 and the first compression plate 143a in opposite directions. 15 [58] That is, the leaf spring 155 is bent by the force to push up from below exerted by the protrusion 153 and then presses the switch by passing through a hole 143a-1 formed at the center of the first compression plate the first compression plate 143a. [59] The leaf spring 155 is preferably made of a material more flexible than the 20 first compression plate 143a and the second compression plate 143b. That is, the leaf spring is preferably made of a material such as resilient metals, alloys, etc. [60] At this time, the resistance of the leaf spring 155 may be controlled by adjusting the material, length, and thickness of the leaf spring 155, the size of the 25 hole 143a-1 formed in the center of the first compression plate 143a, the distance between the leaf spring 155 and the switch 151, and the size of the protrusion 11 153, thereby controlling the compressive force limit. [61] Here, the hole 143a-1 formed in the first compression plate 143a is preferably formed larger than the protrusion 153, and the leaf spring 155 is preferably formed larger than the hole 143a-1 formed in the first compression 5 plate 143a. [62] On the other hand, the trash container 100 in accordance with the present invention further includes a height sensing module 160 to detect the height of the trash piled up in the inner container 120. [63] Fig. 7 shows schematically a configuration of a height sensing module 10 applied to the present invention. [64] The height sensing module 160 includes a fluorescent tape 161, a camera 163 and an image analysis unit 165. [65] The fluorescent tape 161 is used to recognize the height of the trash piled up in the inner container 120 and is installed inside the inner container 120 but is 15 installed in a position higher than the upper end of the inner container 120. [66] The camera 163 is installed at the same height as the fluorescent tape 161 on the opposite side of the fluorescent tape 161 and photographs the fluorescent tape 161 to send the photographed image to the video analysis unit 165. 20 [67] The image analysis unit 165 analyzes the image received from the camera 163, determines that the trash is piled up above a certain height if the fluorescence tape 161 is not visible in the image and transmits a detection signal to the control unit 180. [68] That is, as shown in Fig. 7A, while the fluorescence tape 161 is visible in 25 the image received from the camera 163 when the trash is piled up below the upper end of the inner container 120, the fluorescence tape 161 is invisible in the 12 image received from the camera 163 since it is covered with the trash when the trash is piled up above the upper end of the inner container 120. Thus, when the fluorescence tape 161 is invisible in the image, the image analysis unit 165 transmits the detection signal to the control unit 180 so that the trash can be 5 compressed. [69] In addition, when the image analysis unit 165 detects smoke and flames in the image by analyzing the image received from the camera 163, it determines that a fire breaks out and notifies it to the control unit 180. [70] Meanwhile, the trash container 100 in accordance with the present 10 invention further includes a safety module 170 that prevents the trash from being thrown into the inner container by closing the inlet when the compression plate 143 is lowered for compression. [71] Fig. 8 shows schematically a configuration of the safety module applied to the present invention. 15 [72] In Fig. 8, an opening and closing door 171 has an intermediate portion that is rotatably hinged by a hinge shaft 173 in a trash inlet passageway and opens or closes the trash inlet passageway in accordance with the rising or falling of the compression plate 143. [73] That is, the opening and closing door 171 opens the trash inlet 20 passageway, with help of a weight body 175 that is installed on a portion extended toward a direction of the compression plate with reference to the hinge shaft 173, by pushing up the weight body by the compression plate 143 and rotating the opening and closing door 171 in an opening direction when the compression plate 143 is raised. On the other hand, when the compression 25 plate 143 is lowered, the opening and closing door 171 rotates in a closing direction due to the weight of the weight body 175, thereby closing the inlet 13 passageway. [74] Here, a support 179 is installed at the end of the compression plate 143 in a direction of the trash inlet passageway to push up the weight body 175 when the compression plate 143 is raised and support the weight body 175 so as to 5 prevent it from being fallen down when the rising of the weight body 175 is completed. [75] On the other hand, a stopper 177 is installed inside the trash inlet passageway and serves to restrict the closing position of the opening and closing door 171. The stopper may be made of a material such as magnets. 10 [76] Fig. 9 is a block diagram of electrical components of a trash container in accordance with an embodiment of the present invention. [77] In Fig. 9, the solar cell 130 is arranged in the outer container and functions to convert light energy of sun rays into electrical energy. An array may be formed by one or more solar cells 130. The solar cell 130 may have various 15 shapes such as a panel type, curved type, etc. and is not particularly limited. The solar cell 130 may be arranged at least a portion of the outer surface of the outer container 110. For example, the solar cell 130 may be arranged at least one of at least a portion of the upper surface, at least a portion of the rear surface, and at least a portion of the side surface of the outer container 110. The solar 20 cell 130 includes a photo absorption layer. For example, the material used as the photo absorption layer may be a crystalline silicon (c-Si), amorphous silicon (a-Si), multi-crystal silicon (mc-Si), nanocrystalline silicon (nc-Si), compound semiconductor such as CIGS (CulnGaSe 2 ), CdTe, etc., organic compound, material having multi-junction, or the like. Amorphous silicon may be a 25 hydrogenated amorphous silicon (a-Si: H), and multicrystalline may be hydrogenated multi-crystalline silicon (mc-Si: H). nanocrystalline silicon may be 14 hydrogenated nanocrystalline silicon (nc-Si: H). The photo absorption layer may form a PIN junction or PN junction. The PIN junction may be formed in an order of P, I and N or may be formed in an order of N, I and P. The PN junction may be formed in an order of P and N, or may be formed in an order of N and P. 5 [78] A charger 135 is charged with the electrical energy converted by the solar cell 130 and supplies the charged electrical energy to the motor 141 that is a driving source of the compression module 140 under a control of the control unit 180. [79] The compression module 140 is installed inside the outer container 110 10 and is supplied with the electrical energy from the charger 135 to run and compress the trash piled up in the inner container 120 under the control of the control unit 180. [80] The height sensing device 160 serves to sense the height of the trash piled up in the inner container 120. When the height sensing module senses the 15 trash piled up over a preset height, it sends a sensing signal to the control unit 180. [81] Thus, in response to the sensing signal received from the height sensing device 160, the control unit 180 drives the compression module 140 to compress the trash. 20 [82] Meanwhile, the force detection module 150 is installed on the compression plate 143 in direct contact with the trash to compress the trash and detects a force above a preset threshold exerted by the compression plate 143. When the force detection module 150 detects the force above a preset threshold exerted on the compression plate 143, it transmits the detection signal to the 25 control unit 180. [83] Thus, upon receiving the detection signals from the force detection 15 module 150, the control unit 180 terminates the falling compression depending on the detection signal and controls the compression module 140 to return the compression plate 143 to the original position. [84] A communication unit 190 communicates with a remote control center 5 under a control of the control unit 180. [85] If the control unit 180 receives the sensing signal from the height sensing module 160 within a certain period of time after returning the compression plate 143 to the original position by controlling the compression module 140 based on the detection signal received from the force detection module the force detection 10 module 150, it determines that the trash is fully filled with the inner container 120 and then transmits a trash collection requesting signal through the communication unit 190 to the remote control center. [86] In addition, if the control unit 180 is notified of the outbreak of fire from the image analysis unit 165 of the height sensing module 160, it transmits a fire 15 signal to the remote control center so as to enable initial fire suppression. [87] Fig. 10 is a flowchart describing a method for controlling the trash container in accordance with an embodiment of the present invention. [88] First, when the height sensing module 160 detects a state where the trash is piled up above a preset height in the inner container 120, it sends a sensing 20 signal to the control unit 180 in block S10. [89] Upon receiving the sensing signal from the height sensing module 160 through block S1 0, the control unit 180 supplies the electrical energy to the motor that is a driving source of the compression module 140 to drive the motor 141 based on the sensing signal from the height sensing module 160 in block S20. 25 [90] When the motor 141 is driven through block S20, the pair of screws 142 that are dynamically coupled to the motor 141 are lowered and the compression 16 plate 143 installed on the bottom of the compression plate 143 presses and compresses the trash in block S30. [91] During the compression of the trash through block S30, when a force above a preset threshold exerted on the compression plate 143 is detected by the 5 force detection module 150 in block S40, the control unit 180 controls the driving of the motor 141 to terminate the lowering compression based on the detection signal received from the force detection module 150 and raises the screws 142 to return the compression plate 143 to the original position in block S50. [92] After returning the compression plate 143 to the original position through 10 block S50, if the sensing signal is received from the height sensing module 160 that detects a state where the trash is piled up above the preset height within a certain period of time in block S60, it is determined that the inner container 120 is full of the trash and the trash collection requesting signal to the remote control center through the communication unit 1790 in block S70. 15 [93] Meanwhile, the image analysis unit 165 of the height sensing module 160 analyzes the image provided by the camera 163, determines that a fire breaks out when detecting smoke and flames in the image through the analysis of the image received from the camera 163, and notifies the outbreak of fire to the control unit 180. In response to the outbreak of fire, the control unit 180 20 transmits the fire signal to the remote control center. [94] While the present invention has been described with reference to specific items such as concrete components, limited embodiments and drawings, it is merely supplied to aid in full understanding of the present invention, is not limited to the above embodiments, and may be made various changes and modifications 25 of the disclosure to a person having ordinary skill in the art to which the invention belongs. 17 [95] Therefore, the spirit of the present invention is defined by the appended claims rather than by the foregoing embodiments, and all changes and modifications that fall within bounds of the claims, or equivalents of such bounds are intended to be embraced by the scope of the present invention. 5 INDUSTRIAL APPLICABILITY [96] In accordance with the trash container and the method for controlling the trash container of the present invention, it is possible to reduce maintenance costs associated with the trash collection by compressing the trash and reducing 10 the volume of the trash when the trash is piled up in the trash container so that the trash container is filled with much more trash. [97] Further, it is possible to compress the trash with a stable force by compressing the trash through the use of the compression module including a pair of screws. 15 [98] Further, it is possible to maintain the aesthetics since the trash container is collected in a timely manner by transmitting a trash collection trash collection requesting signal to a remote control center when a certain amount of the trash is piled up in the trash container. [99] In addition, it is possible to enable an early fire suppression by detecting a 20 fire break out in the trash container and transmitting a fire outbreak signal to the remote control center. 18
