FIG. 1 is a perspective view showing an outer shape of a food waste grinding and drying apparatus 11 according to an embodiment of the present invention, and FIG. 2 is a view showing the lid of the grinding and drying apparatus shown in FIG. 1 opened .

As shown in the figure, the food waste pulverization and drying apparatus 11 according to the present embodiment includes a case 13 having a box shape and having a pulverizing cylinder 21 therein, a support 13 for supporting the case 13, And a lid 15 which is openably and closably provided on the upper portion of the case 13.

The case 13 is a part including a pulverizing cylinder 21, a driving part, a discharger 23, and the like, and the upper end thereof is finishing in consideration of aesthetics. That is, a cover plate 13b is provided between the outer peripheral surface of the upper end of the pulverizing casing 21 and the inner wall of the upper end of the case 13, so that the inner space of the case 13 is not visible to the outside.

The cover plate 13b is fixed to the inner wall surface of the case 13 by accommodating the upper end portion of the pulverizing tub 21 at its central portion and also serves to support the pulverizing tub 21 so as not to be shaken. It goes without saying that the cover plate 13b can be separated from the case 13 as necessary. In this way, the crusher 21 can be separated from the case 13.

In addition, a discharge port (19) is disposed on the front surface of the case (13). The discharge port (19) is a passage through which the processed material after the pulverization is discharged. That is, when food waste is put into the crusher 21, the lid 15 is closed, and the control unit 17 is operated, the processed material is discharged through the discharge port 19. [ The processed product is in the state that the food garbage is pulverized and dried.

The lid 15 is rotatably mounted on the upper end of the case 13 and rotates up and down to open and close the pulverizing cylinder 21. [ The upper end of the case 13 and the upper end of the crushing tube 21 have the same height so that when the lid 15 is closed the upper end of the crushing case 21 and the case 13 abuts against the bottom surface of the lid 15.

As will be described later, the lid 15 has a hollow internal space (15d in Fig. 3), and has discharge means for discharging the air inside the pulverizing cylinder to the outside of the pulverizing cylinder in the internal space 15d. The discharging means includes an air supply / exhaust fan (27, 25), a dehumidifier (39 in FIG. 4), a sterilizer (41), and the like. The discharging means will be described later.

As shown in Fig. 2, an exhaust hole 15b and an air supply hole 15c are formed in the bottom surface of the lid 15. As shown in Fig. The exhaust hole 15b is a hole for upwardly passing the damp air in the crusher 21 and the air supply hole 15c is a passage for sending the air inside the lid 15 to the crusher 21.

On the upper surface of the lid 15, a control unit 17 is also located. The control unit 17 is, for example, an on-off button, a crushing button, a discharge button, a drying button, and the like as various control switches for controlling the crushing and drying apparatus 11. The operation of the control unit 17 will also be described later.

Reference numeral 15a denotes a handle groove. The finger end can be inserted into the handle groove 15a and the lid 15 can be lifted.

FIG. 3 is a view for explaining the internal structure of the food waste grinding and drying apparatus 11 shown in FIG. For convenience, the pedestal 14 is omitted in the drawing.

As shown, the food waste pulverization and drying apparatus 11 according to the present embodiment includes a box-shaped case 13 having an internal space 13a, a motor 31 provided inside the case 13, A crushing part 61 disposed above the motor 31 for receiving power from the motor 31 and for crushing food waste and a crushing part 61 for crushing the crushed material from the crushing part 61 to the outside of the case 13 And an ejector 23 for ejecting the ink.

One exhaust fan 25 and two air supply fans 27 and a filter 29 are provided in the inner space 15d provided by the lid 15.

First, the motor 31 is vertically installed at the center of the inner bottom of the case 13, and generates a rotation torque by electric power supplied from the outside. Further, a lower clutch 33 is fixed to the driving shaft of the motor 31. The lower clutch 33 is a member having teeth formed on its upper surface, and transmits the rotational force of the motor 31 to the upper clutch 35.

The crushing unit 61 includes a crushing cylinder 21 opened to the top, a main blade 47 installed to be rotatable in the crushing cylinder 21 to crush food waste introduced into the crushing cylinder, A fixed blade (45, 51) tightly fixed to the inner wall surface of the pulverizing casing (21), a rotating blade (45, 51) rotating with the main blade (47) And has wing blades (43, 53) for crushing food garbage.

The main blade 47 and the wing blades 43 and 53 engage with the blade shaft 37 to rotate upon rotation of the shaft of the blade shaft 37 to crush food waste.

An upper clutch 35 is fixed to the lower end of the blade shaft 37. The upper clutch 35 meshes with the lower clutch 33 and transmits the rotational force of the motor 31 to the blade shaft 37. By applying the upper and lower clutches 35 and 33 in this way, it is possible to separate the pulverizing cylinder 21 from the motor 31. [

The structure of the interior of the pulverizing cylinder 21 will be described in detail with reference to FIGS. 5 to 8. FIG.

The ejector 23 is for discharging the pulverized material to the outside of the case 13. [ A semicircular hole (21c in Fig. 9) is formed on the bottom surface 21b of the pulverizing cylinder 21 to discharge the processed material in the pulverizing cylinder 21. [

The detailed configuration of the ejector 23 will be described first with reference to FIG.

As shown in the drawing, the discharge unit 23 includes an upper casing 23a tightly fixed to a bottom surface of the pulverizing casing 21, and a lower casing 23a coupled to a lower portion of the upper casing 23a to provide a receiving space 23g. A casing 23b, a discharge rotor 23n rotatably installed in the accommodating space 23g, a discharge motor 23c for driving the discharge rotor 23n, and a speed reducer 23d.

First, the upper casing 23a has an inlet port 23e and an outlet port 19 having the same size as the semicircular hole 21c. The inlet port 23e is a hole through which the processed product having passed through the semicircular hole 21c passes downward. The processed product having passed through the inlet 23e is accumulated in the receiving space 23g and then discharged to the outlet 19 according to the operation of the outlet rotor 23n.

In addition, a fixing sensor 23m is provided on the inner circumferential surface of the upper casing 23a. The fixed sensor 23m is a sensor corresponding to the moving sensor 23k fixed to the discharging rotor 23n. In a state where the moving sensor 23k and the fixed sensor 23m face each other, a blocking plate 23t to be described later cuts off the charging port 23e.

That is, the movement sensor 23k and the fixed sensor 23m are designed to face each other at a position where the blocking plate 23t blocks the charging port 23e. The movement sensor 23k and the fixed sensor 23m generate a state signal facing each other and send it to the control unit 17. [ As a result, the control unit 17 can know whether the current inlet 23e is closed or open through the movement sensor 23k and the fixed sensor 23m.

The lower casing 23b is coupled to a lower portion of the upper casing 23a to constitute a discharge cylinder case 23u and supports the discharge rotor 23n rotatably. Further, a shaft hole 23v is provided at the bottom of the lower casing 23b. The shaft hole 23v is a hole through which the drive shaft 23f of the speed reducer 23d passes.

The discharge rotor 23n includes a semicircular shielding plate 23t for opening and closing the charging port 23e through a rotational motion and a semicircular shielding plate 23t integrally formed at a lower portion of the shielding plate 23t and directly connected to the driving shaft 23f, A pushing blade 23r extending in the opposite direction around the rotation axis and an elastic blade 23s fixed to the pushing blade 23r and in contact with the inner wall surface of the discharge case 23u, And a movement sensor 23k provided at one side of the pushing blade 23r.

The discharge rotor 23n is rotated by the rotational force transmitted from the speed reducer 23d and discharges the processed product A to the outside of the case 13 through the process shown in FIG.

The pushing wings 23r and the elastic wings 23s take the form of, for example, a wavy shape, and serve to push the processed material into the discharge cylinder case 23u toward the discharge port 19 side.

The elastic blade 23s is a synthetic resin or rubber plate having an elastic force and is fixed to the one-side pushing blade 23r and is in contact with the inner wall surface of the discharge cylinder case 23u in an elastically deformed state. The elastic blade 23s has an elastic restoring force and resiliently urges the inner wall surface of the discharge cylinder case 23u in the direction of the arrow f in Fig.

Particularly, during the process of rotating the discharge rotor 23n, the elastic blade 23s jumps in the direction of the arrow z due to its elastic restoring force as it approaches the discharge port 19 side as shown in Fig. 10E. The processed product A staying in the inside of the discharge port 19 is struck by the elastic blade 23s and is thrown out of the discharge port 19. [

Although only one resilient vane 23s is shown in the figure, it can of course be mounted on the opposite side.

The discharge motor 23c is turned on and off when the discharge button of the controller 17 is pressed. The rotational force output from the discharge motor 23c is output to the drive shaft 23f through the speed reducer 23d.

Reference numeral 21e denotes a center hole. The center hole 21e is a hole through which the blade shaft (37 in Fig. 3) passes.

Returning to FIG. 3, the description will be continued.

As described above, one exhaust fan 25 and two air supply fans 27 are provided in the inner space 15d of the lid 15. The exhaust fan 25 serves to draw air in the inside of the crusher 21 and the air supply fan 27 serves to remove air from the outside of the crusher 21, And a part of the air drawn up by the exhaust fan 25 into the crusher 21.

An exhaust pipe 25a is connected to the exhaust fan 25 and a filter 29 is attached to the exhaust pipe 25a. Therefore, the air raised from the crusher 21 by the exhaust fan 25 passes through the filter 29, is purified, and then is discharged to the atmosphere.

The arrangement of the air supply fan 27 and the exhaust fan 25 is appropriately designed in consideration of the positions of the air supply holes 15c and the exhaust holes 15b.

On the other hand, the size of the case 13 can be changed variously. If it is for home use, it can be stored in the lower part of the sink ball. In addition, a wheel (not shown) may be provided in the lower portion of the case 13 in addition to the pedestal 14. In the case of installing the wheels, the crushing and drying apparatus 11 can be moved very easily to a desired place.

Fig. 4 is a view showing another example of the food waste grinding and drying apparatus 11 shown in Fig. 1. Fig.

The same reference numerals as those of the above-mentioned reference numerals indicate the same members having the same function.

Referring to FIG. 4, it can be seen that a dehumidifier 39 and a sterilizer 41 are installed in the inner space 15d of the cover 15. The dehumidifier 39 sucks air in the crusher 21 to remove moisture, and then transfers the moisture to the sterilizer 41 through the connection manifold 39a.

The sterilizer 41 receives air from the dehumidifier 39 and sterilizes the air and exhausts the air through the exhaust pipe 41b or sends it to the crusher 21 through the dry air supply pipe 41e. Inside the sterilizer 41, a UV lamp 41a for sterilizing air is provided.

FIG. 5 is a partially cutaway perspective view for explaining the construction of the crushing unit 61 in the food waste crushing and drying apparatus according to the embodiment of the present invention, FIG. 6 is a view for explaining the operation principle of the crushing unit shown in FIG. Respectively.

As shown in the figure, the crushing unit 61 includes a crushing cylinder 21 having a cup shape and opened to the top, a pair of main blades 47 provided in the crushing cylinder 21, Includes a wing blade (43) and a helical fixing blade (45).

The main blade 47 and the straight wing blade 43 are fixed to the blade shaft 37 and rotate by the rotation of the shaft of the blade shaft 37 to cut and crush the surrounding food waste. The blade shaft 37 is a shaft member that has passed through a center hole 21e at the center of the bottom surface 21b, and receives the rotational force of the motor to rotate in the axial direction.

The main blades 47 are vertically spaced with a spacer 49 therebetween. The main blade 47 crushes food waste located at the center of the inside of the crushing space 21a.

The straight wing blade 43 takes the form of a band and its central portion is fixed to the blade shaft 37 and rotates together with the main blade 47 to cut and crush the food waste.

The linear wing blades 43 include a horizontal extending portion 43a extending in the opposite direction while being fixed to the blade shaft 37 and a pair of upper and lower extending portions 43a, And a linear cutting portion 43b. Particularly, the linear cutting portion 43b is spaced apart from and parallel to the inner wall surface of the pulverizing casing 21, and has blade portions 45a at both ends in the width direction.

On the other hand, a spiral-shaped fixing blade 45 is provided on the inner wall surface of the pulverizing cylinder 21. The helical fixing blade 45 is a metal member having a rectangular cross-sectional shape and extends spirally from the upper end of the pulverizing cylinder toward the bottom surface 21b. Particularly, at both end portions in the width direction of the helical fixing blade 45, a blade portion 45a is formed. The number of the helical fixing blades 45 may vary depending on the case.

The helical fixing blade 45 and the straight cutting portion 43b are mutually interviewed. That is, the linear cutting portion 43b rotates in a state of being interposed in the helical fixing blade 45. In particular, the straight cutting portion 43b is deflected in the direction of arrow a by the centrifugal force generated during rotation, and contacts the helical fixing blade 45 more closely.

In this way, the linear cutting portion 43b rotates in contact with the helical fixing blade 45, so that the crossing motion between the blade portions 43c and 45a is performed. That is, the food waste placed between the spiral fixed blade 45 and the blade portion of the straight cutting portion 43b is cut by the crossing motion of the blade portion.

The food waste to be crushed by the main blades 47 in the crusher 21 is pushed by the centrifugal force against the wall surface of the crusher 21 during the crushing so that the food waste pushed by the crusher 21 is cut into a straight cut portion 43b and the helical fixed blade 45. [0064] In particular, since the straight cutting portion 43b covers most of the wall surface in the pulverizing cylinder 21, the grinding ratio is high and the working time is very short.

FIG. 7 is a view showing another constitution of the crushing section 61 in the food waste crushing and drying apparatus 11 according to the embodiment of the present invention, and FIG. 8 is a view showing the operation principle of the crushing section shown in FIG. It is a flat section for explaining.

As shown in the drawing, a spiral wing blade 53 and a linear fixed blade 51 are applied to the crushing unit 61 according to another example.

The spiral wing blade 53 includes a horizontally extending portion 53b having a center portion fixed to the blade shaft 37 and extending in the opposite direction and a bending portion 53b integrally formed with the end portion of the horizontally extending portion 53b, And a helical cutting portion 53c extending upward in the spiral direction.

The linear fixed blade 51 is a member extending linearly from the upper end of the pulverizing casing 21 toward the bottom surface 21b. The linear fixed blade 51 is a rod-shaped member having a rectangular cross section and has blade portions 51a at both ends in the width direction. The number of the linear fixed blades 51 to be installed may vary as needed.

The helical cutting portion 53c takes the form of a band, and the two pieces form a pair and are symmetrical about the blade shaft 37.

Needless to say, the blade portion 53a is also formed at both end portions in the width direction of the helical cutting portion 53c.

The helical cutting portion 53c is rotated in a state in which the linear fixed blade 51 is interposed. The linear fixed blade 51 is more closely contacted by the centrifugal force generated during rotation.

When rotating, the helical cutting portion 53c having the above-described configuration intersects with the linear fixed blade 51, cutting and crushing the food waste therebetween.

Since the helical cutting portion 53c is inclined in a spiral manner and the straight fixing blade 51 extends vertically, crossing motion is possible and the food waste introduced between the blade portions 53a and 51a can be cut.

10A to 10E are views showing the operation principle of the above-described discharger 23. 10A is a state in which the charging port 23e is completely shut off, and FIG. 10B is a state in which the charging port 23e is fully opened.

Referring to FIG. 10A, it can be seen that the blocking plate 23t completely blocks the charging port 23e. The inlet 23e is always closed except when discharging the processed product.

In addition, the elastic blade 23s is pushed against the inner wall surface of the discharge cylinder case 23u and repelled in the direction of the rotation shaft 23p. The movement sensor 23k faces the fixed sensor 23m.

In this standby state, the food waste is put into the crusher 21, the lid 15 is closed, and when the crushing button of the control unit 17 is pressed, the main blade 47 and the wing blade 43 , 53) rotates to crush food waste. At this time, the food waste is dried simultaneously by pressing the dry button.

After the crushing and drying are completed, the crushing and drying is completed and the drain button is pressed. When the discharge button is pressed, the discharge motor 23c is operated, and the discharge rotor 23n is rotated accordingly. As the discharge rotor 23n rotates continuously, the charging port 23e is repeatedly opened and closed.

The processed product A in the pulverizing cylinder 21 falls through the semicircular hole 21c and the charging port 23e into the discharge cylinder case 23u while the charging port 23e is opened. As shown in Fig. 10B, the processed product A falls while the blocking plate 23t is deflected from the inlet 23e and collects in the discharge cylinder case 23u.

The processed product A collected in the discharge case 23u is pushed by the pushing blade 23r toward the discharge port 19 side in accordance with the rotation of the discharge rotor 23n in the direction of the arrow n (see FIGS. 10c and 10d) )

10E, when the discharge blade 23n rotates, the elastic blade 23s (which is hooked to the discharge cylinder case 23u) bounces in the direction of the arrow z, Is strongly pushed against the elastic blade (23s) and pushed out of the discharge port (19). The above process is repeated and the discharge of the processed product A in the discharge case 23u is completed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
