DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a garbage disposal apparatus 10 according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a front view schematically showing a food waste disposal apparatus 10 according to an embodiment of the present invention. Fig. 2 schematically shows the weight measurement unit 200 and the actuator unit 300 shown in Fig. It is a perspective.

1 and 2, a food waste disposal apparatus 10 according to an embodiment of the present invention includes a housing 100, a weight measuring unit 200, and an actuator unit 300. The housing 100 has an inlet 110 and a hopper 130 which are open toward the upper side. In addition, the housing 100 may have opening / closing means (not shown) for opening and closing the inlet 110. The weighing unit 200 is disposed below the inlet 110 and the actuator unit 300 is disposed away from the weighing unit 200.

The weight measuring unit 200 includes a rotating basket 210 for receiving food waste flowing through the inlet 110 and a load cell 230 for measuring the weight of the food waste. Here, the rotating basket 210 is rotatably disposed with respect to the first axis 212. The actuator unit 300 may rotate the rotating basket 210 about the first axis 212. The spin basket (210) includes a basket spin axis (215) extending along a first axis (212).

The weight measuring unit 200 may further include a guide portion 250, a rack gear 270, and a pinion gear 290. The guide portion 250 is disposed on the load cell 230. The rack gear 270 can be disposed on the guide portion 250 and can be slid. The pinion gear 290 is engaged with the rack gear 270 at the upper portion of the rack gear 270. The pinion gear 290 is connected to the rotation axis of the rotating basket 210 extending along the first axis 212. Accordingly, the rotating basket 210 can rotate about the first axis 212 in accordance with the sliding of the rack gear 270. Both ends of the rotating basket 210 can be supported by the bracket 220. The bracket 220 is disposed on the load cell 230. At this time, the bracket 220 may be provided with a bearing.

On the other hand, both the bracket 220, the guide portion 250, the rack gear 270, the pinion gear 290, and the first shafts 212 of the rotating basket 210 are disposed on the load cell 230. That is, all components that rotate the rotating basket 210 are disposed on the load cell 230. In particular, the actuator unit 300 that slides the rack gear 270 is disposed in the housing 100 spaced from the weighing unit 200. Therefore, when measuring the weight of the food waste, the error can be removed and the weight of the food waste can be accurately measured. Particularly, since the cable 311 of the actuator unit 300 does not affect the weight measurement of the load cell 231, accurate weight measurement is possible. When the motor such as the actuator unit 300 is disposed on the load cell 231, the end of the power cable connected to the motor or the like is supported by the housing or the like to affect the load cell 231.

Further, the structure for rotating the rotating basket 210 is simple, and the manufacturing cost is also reduced.

The guide unit 250 may include a main guide plate 251 and an auxiliary guide plate 253. The main guide plate 251 is disposed on the load cell 230 and extends along a second axis intersecting or perpendicular to the first axis 212. The pair of auxiliary guide plates 253 are disposed on opposite sides of the main guide plate 251 so as to face each other. Therefore, the rack gear 270 can be slidably guided between the pair of auxiliary guide plates 253.

The actuator unit 300 includes a first cylinder 310 and a second cylinder 330. The first cylinder 310 may be disposed in the housing 100 so as to face the second cylinder 330 with the rack gear 270 therebetween. In one embodiment, the first cylinder 310 includes a first rod 311 that is advanced or retracted along a second axis perpendicular to the first axis 212. The second cylinder 330 includes a second rod 331 that advances or retreats along the second axis.

When the first rod 311 of the first cylinder 310 advances, the rack gear 270 slides in one direction. The first rod 311 can be advanced back to the maximum after the continuous operation. When the second rod 331 of the second cylinder 330 advances, the rack gear 270 slides in the other direction. The second rod 331 can be advanced back to the maximum after the continuous operation. That is, the first rod 311 and the second rod 331 are spaced from the gravimetric unit 200 during the weight measurement of the food waste. After the weighing, the rotating basket 210 is rotated by the operation of the first rod 311 and the second rod 311 so that the food waste falls down to the lower portion of the rotating basket 210.

3 is a cross-sectional view of a hopper 130 and a rotating basket 210 according to an embodiment of the present invention.

1 to 3, the hopper 130 may include an upper hopper 131 and a lower hopper 133. The upper hopper 131 communicates with the inlet 110 and guides the food waste introduced into the inlet 110 to the lower hopper 133. The hopper 130 has a through hole through which the basket rotating shaft 215 of the rotating basket 210 passes. Here, the hopper 130 has a through-hole having a diameter larger than the diameter of the basket rotation shaft 215. [ Thus, the rotating basket 210 does not contact the hopper 130.

The lower hopper 133 may include a cylindrical portion 133b and a curved portion 133a. The cylindrical portion 133b has a rectangular duct shape and surrounds the rotating basket 210. The first axis 212, which is the rotation axis of the rotating basket 210, traverses the cylindrical portion 133b. The curved portion 133a has a curved surface having the same curvature as the circular plate 213 with respect to the first axis 212. [ The hopper 130 according to the embodiment of the present invention has the curved portion 133a and the cylindrical portion 133b so that the hopper 130 contacts the rotating basket 210 despite the rotation of the rotating basket 210 You can wrap it.

That is, the gap between the rotating basket 210 and the hopper 130 can be minimized. Therefore, the structure of the food waste disposal apparatus 10 can be simplified and miniaturized. In addition, the food waste is prevented from flowing between the rotating basket 210 and the hopper 130, and the weight can be measured without loss of food waste discharged into the inlet 110.

FIG. 4 is a view showing one embodiment of the storage unit 400 shown in FIG. 1, and FIG. 5 is a view showing the transfer unit 500 shown in FIG.

1, 2, 4 and 5, a food waste disposal apparatus 10 according to an embodiment of the present invention includes a storage unit 400, a transfer unit 500, a processing unit 600, and a control unit 700. [ As shown in FIG. The storage unit 400 receives the food waste dropped from the rotating basket 210. The transfer unit 500 transfers the food waste accommodated in the storage unit 400 to the processing unit 600. The processing unit 600 can dry and disassemble the food waste. The control unit 700 can control the operations of the weighing unit 200, the actuator unit 300, the storage unit 400, the transfer unit 500 and the processing unit 600. [

The storage unit 400 may include a storage vessel 410, a pair of drive shafts 430, a rotating shaft 450, a ribbon screw 470, a stirring plate 490 and a scraper 420. The lower portion of the storage container 410 may have a semi-cylindrical shape. A rotating shaft 450 is disposed inside the storage container 410. The rotating shaft 450 traverses the storage container 410. The storage container 410 may have a pair of bearings 431 disposed facing each other. Each of the pair of drive shafts 430 is supported by bearings 431. The rotating shaft 450 may be connected to the driving shaft 430 by a flange 451.

The ribbon screw 470 may be secured to the rotating shaft 450 with a ribbon support 471. The ribbon screw 470 may extend in a spiral shape along the longitudinal direction of the rotating shaft 450. The stirring plate 490 may be fixed to the rotating shaft 450 with a stirring support 491. The stirring plate 491 may have a rectangular plate shape.

In one embodiment, the ribbon screw 470 is spaced further from the outer circumferential surface of the rotating shaft 450 than the stirring plate 490. That is, the first distance 472, which is the shortest distance from the rotating shaft 450 to the ribbon screw 470, is larger than the second distance 492, which is the longest distance from the rotating shaft 450 to the stirring plate 490. Thus, the ribbon screw 470 can stir food waste adjacent to the inner surface of the storage container 410, and the stirring plate 490 can stir the food waste adjacent to the rotating shaft 450. The ribbon screw 470 moves the food waste from one end of the rotating shaft 450 to the other end and the stirring plate 490 moves the food waste to the other end of the rotating shaft 450 at one end.

Meanwhile, the scraper 420 may be disposed on at least one of the rotating shaft 450 and the driving shaft 430. In one embodiment, the scraper 420 may be disposed between the flange 451 and the bearing 431. The scraper 420 can scrape off the food waste attached to the surface of the storage container 410 adjacent to the bearing 431 while rotating along with the rotation of the rotating shaft 450 or the driving shaft 430. As a result, the food waste can be prevented from flowing into the bearing.

The transfer unit 500 includes a transfer screw 510, a top gate 530 and a bottom gate 550. The transfer screw 510 can transfer the food waste introduced into the lower gate 550 to the processing unit 600 through the upper gate 530.

The configuration of the garbage disposal apparatus 10 according to the embodiment of the present invention has been described so far. Hereinafter, the operation of the food waste disposal apparatus 10 according to an embodiment of the present invention will be described.

Referring to FIGS. 1 to 5, the food waste flows through the inlet 110. The food waste falls into the rotating basket (210). The rotating basket (210) is wrapped tightly by the hopper (130) while rotating about the first axis. Therefore, it is possible to prevent the loss of food waste and accurately measure the food waste per household.

The control unit 700 measures the weight of the food waste through the weight measuring unit 200. At this time, a rotating basket 210 or the like is disposed on the load cell 230, and the actuator unit 300 is not spaced apart from the load cell 230. Therefore, the weight of the food waste can be measured without error.

After the weight is measured, the controller 700 drives the actuator unit 300 to rotate the rotating basket 210. For example, the controller 700 drives the first cylinder 310 and then the second cylinder 330. That is, the first rod 311 advances to slide the rack gear 270 in one direction. Thereafter, the first rod 311 is moved backward. When the second rod 331 advances, the rack gear 270 slides in the other direction. Thereafter, the second rod 331 is moved backward. In this process, the rotating basket 210 may be rotated about the first axis 212. The structure for rotating the rotating basket 210 by advancing and retracting the first rod 311 and the second rod 331 is to prevent contact with the load cell 230 to eliminate an error.

By the rotation of the rotating basket (210), the food waste falls to the storage container (410). The control unit 700 arbitrarily rotates the rotating shaft 450 to stir the food waste concentrated at a specific position of the storage container 410 with the ribbon screw 470 or the stirring plate 490 to thereby cool the entire . At this time, the controller 700 blocks the lower gate 550.

The control unit 700 drives the rotating shaft 450 and the feed screw 510 to transfer the food waste to the processing unit 600. [ At this time, the controller 700 opens the lower gate 550 and the upper gate 530. Food waste can be introduced into the outlet 440 by the ribbon screw 470. Further, the food waste is conveyed to the processing unit 600 by the conveying screw 510. That is, the control unit 700 distinguishes between the case of distributing the food waste concentrated in the storage container 410 and the case of transferring the food waste to the processing unit 600, and the storage unit 400 and the transfer unit 500 . Food waste can be dried and disassembled by the treatment unit 600.

Although the invention made by the present inventors has been described concretely with reference to the above embodiments, the present invention is not limited to the above embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.
