By forming the pushing surfaces 34a on both side surfaces of the stirring arm 33, the first rotary crushing blade 26 can apply a downward pressing force to the garbage that is in contact with the pushing surface 34a by bidirectional rotation. it can. Thereby, the 1st rotation crushing blade 26 takes in garbage by rotation operation, and pushes it into the crushing blade of a lower stage.

  Moreover, the edge 34b is formed in the lower end side of the pushing surface 34a, respectively, and the 1st rotation crushing blade 26 functions as a crushing blade which crushes raw garbage roughly in cooperation with the 2nd fixed crushing blade 27.

  Further, the first rotary crushing blade 26 has a handle 33 a formed on the upper surface of the stirring arm 33. Since the first rotary crushing blade 26 is configured to rotate integrally with each rotary crushing blade, by forming the handle 33a on the uppermost first rotary crushing blade 26, without directly touching the crushing blade, Each rotary crushing blade can be rotated.

  That is, when the crushing unit 4 shown in FIG. 6 is attached to the hopper 3 as shown in FIG. 1, when adjusting the direction of each rotary crushing blade for connection with the drive shaft 5a, if the handle 33a is operated, The direction of the rotary crushing blade can be adjusted without touching the crushing blade.

  The first rotary crushing blade 26 has a shaft mounting hole 32 a formed through the bearing portion 32. The shaft attachment hole 32a has a substantially D-shaped cross section, and is fitted in a state in which a shaft portion described later of the third rotary crushing blade 28 cannot rotate.

  The second fixed crushing blade 27 includes two arms 36 extending horizontally from the hub 35 at intervals of 180 degrees. Each arm 36 has a flat plate shape, and edges 37a and 37b are formed on the upper and lower ends of both side surfaces, and functions as a crushing blade in cooperation with the first rotary crushing blade 26 and the third rotary crushing blade 28 described above.

  A tab 38 is formed at the tip of each arm 36. The tab 38 is fitted in the vertical groove 31b of the housing 31 shown in FIG. 6 to restrict the rotation of the second fixed crushing blade 27. Further, a leg 38 a is formed on the tab 38, and a gap with a predetermined height is formed between the second fixed crushing blade 27 and the fourth fixed crushing blade 29. Further, the inner diameter of the hub 35 is larger than the diameter of a shaft portion described later of the third rotary crushing blade 28 and has a dimension that does not interfere with the shaft portion of the third rotary crushing blade 28.

  The third rotary crushing blade 28 includes three arms 40 that extend radially from the hub 39 at intervals of 120 degrees. Each arm 40 has a comb tooth portion 40a having a predetermined pitch on the bottom surface.

  The hub 39 of the third rotary crushing blade 28 includes a first shaft portion 39 a on the upper side of the formation surface of the arm 40 and a second shaft portion 39 b on the lower side of the formation surface of the arm 40. The first shaft portion 39a fits rotatably with respect to the hub 35 of the second fixed crushing blade 27. The first shaft portion 39a has a substantially D-shaped cross section on the upper end side, and the shaft mounting hole 32a of the first rotary crushing blade 26 is fitted in a non-rotatable manner. Further, a screw portion 39c to which the nut 41a is fastened is formed at the tip of the first shaft portion 39a.

  The fourth fixed crushing blade 29 is rotatably fitted to the second shaft portion 39b. Further, the second shaft portion 39b is formed with an angular shaft portion 39d that fits in the fifth rotary crushing blade 30 on the lower end side. Further, a screw hole 39e for fastening the screw 41b is formed on the bottom surface of the angular shaft portion 39d.

  The fourth fixed crushing blade 29 has a shape in which a ring 44 surrounds eight arms 43 extending radially in a tangential direction from the hub 42 at equal intervals. On the outer periphery of the ring 44, tabs 44a projecting radially are formed at intervals of 180 degrees. The tab 44a is fitted in the longitudinal groove 31b of the housing 31 shown in FIG. 6 to restrict the rotation of the fourth fixed crushing blade 29.

  The tab 44 a has a predetermined height, and the leg portion 38 a of the second fixed crushing blade 27 is placed on the upper surface of the tab 44 a, so that the tab 44 a is interposed between the second fixed crushing blade 27 and the fourth fixed crushing blade 29. A gap of a predetermined height is formed so that the third rotary crushing blade 28 can enter. Further, the inner diameter of the hub 42 is larger than the diameter of the second shaft portion 39b of the third rotary crushing blade 28, and has a dimension that does not interfere with the second shaft portion 39b.

  In the fourth fixed crushing blade 29, among the eight arms 43, the six arms 43 have comb teeth 43a formed on the upper surface. The comb teeth 43a of the fourth fixed crushing blade 29 has a pitch that meshes with the comb teeth 40a of the third rotary crushing blade 28, and as shown in FIG. 6, the third rotary crushing blade 28 and the fourth fixed crushing blade 29 If 29 is piled up, both the comb-tooth parts 40a and 43a will be in the meshing state in which a slight gap is formed.

  Thereby, the comb tooth portion 43a of the fourth fixed crushing blade 29 crushes the garbage sent from the upper crushing blade in cooperation with the comb tooth portion 40a of the third rotary crushing blade 28.

  As described above, since the number of the arms 40 of the third rotary crushing blade 28 is three and the number of the arms 43 of the fourth fixed crushing blade 29 is eight, the distance between the arms 43 is larger than the distance between the arms 40. narrow.

  For this reason, when the comb teeth 43a are provided on all the eight arms 43, the comb teeth 43a of the fourth fixed crushing blade 29 are always present between the arms 40 of the third rotary crushing blade 28. When a block-shaped raw garbage of a size is thrown in, a phenomenon that the raw garbage does not enter between the arms 40 of the third rotary crushing blade 28 and becomes difficult to be crushed occurs.

  Therefore, in the fourth fixed crushing blade 29, among the eight arms 43, for example, the two arms 43 b are not provided with the comb-tooth portion 43 a, so that the third rotary crushing blade 28 is rotated during the rotation operation. When the arm 43b not provided with the comb tooth portion 43a of the 4 fixed crushing blade 29 is positioned between the arms 40 of the third rotary crushing blade 28, a wide space is formed in the circumferential direction.

  As a result, even when block-shaped garbage having a certain size is introduced, the garbage enters between the arms 40 of the third rotary crushing blade 28, and the comb tooth portion 40a is rotated by the rotation of the third rotary crushing blade 28. And the garbage is crushed in cooperation with the comb teeth 43a of the other arm 43 of the fourth fixed crushing blade 29.

  In addition, since the crushing ability is reduced when the number of the arms 43b not provided with the comb teeth 43a in the fourth fixed crushing blade 29 is large, for example, when the eight arms 43 are provided, the arms 43b without the comb teeth 43a are provided. Is preferably about two.

  In addition, each arm 43 extends radially along the tangential direction of the hub 42, so that when the third rotary crushing blade 28 rotates, the meshing point with the fourth fixed crushing blade 29 is shifted in the circumferential direction. Therefore, the crushing load peak is suppressed and the load is flattened.

  The fifth rotary crushing blade 30 has a disk shape, and a large number of slits 46 are arranged on the entire surface except the central hub 45. In the fifth rotary crushing blade 30 of this example, a plurality of slit groups are formed, and in each slit group, adjacent slits 46 are arranged substantially in parallel.

  The upper surface of the fifth rotary crushing blade 30 is a flat surface and rotates while contacting the bottom surface of each arm 43 of the fourth fixed crushing blade 29. The slit 46 penetrates the fifth rotary crushing blade 30 from the front and back, and a sharp edge is formed at the opening edge of the upper surface side of the slit 46.

  Garbage that has been crushed by the comb tooth portion 40a of the third rotary crushing blade 28 and the comb tooth portion 43a of the fourth fixed crushing blade 29 and dropped onto the upper surface of the fifth rotary crushing blade 30 is caught by the slit 46, and the fifth rotary crushing blade As the blade 30 rotates, it is pressed against the slit 46 and crushed by the edge portion of the slit 46. The finely crushed raw garbage falls downward through the slit 46, passes through the bottom plate 22 of the hopper 3 shown in FIG. 5, and is discharged from the drain pipe connection port 21 to the outside.

  The slit 46 is formed with a stepped portion in the middle, and the opening on the bottom surface side is enlarged from the opening on the upper surface side so that the garbage pushed into the slit 46 can easily fall.

  The hub 45 of the fifth rotary crushing blade 30 has a square hole portion 45a into which the angular shaft portion 39d of the third rotary crushing blade 29 is fitted on the upper surface side. Further, a square hole 45b into which the drive shaft 5a shown in FIG. Further, a through hole 45c through which the screw 41b passes is formed between the square hole part 45a and the square hole part 45b.

  Next, the assembled state of each crushing blade will be described with reference to FIGS. The hub 42 of the fourth fixed crushing blade 29 is rotatably fitted to the second shaft portion 39 b of the third rotary crushing blade 28, and the angular shaft portion 39 d of the second shaft portion 39 b is the corner of the fifth rotary crushing blade 30. It fits into the hole 45a.

  Then, the screw 41b is fastened to the screw hole 39e of the square shaft portion 39d from the square hole portion 45b side of the fifth rotary crushing blade 30, and the third rotary crushing blade 28 and the fifth rotary crushing blade 30 are configured integrally. .

  Further, the hub 35 of the second fixed crushing blade 27 is rotatably fitted to the first shaft portion 39a of the third rotary crushing blade 28, and the shaft mounting hole of the first rotary crushing blade 26 is further fitted to the first shaft portion 39a. 32a is non-rotatably fitted.

  And the nut 41a is fastened to the screw part 39c of the 1st axial part 39a, and the 1st rotation crushing blade 26 and the 3rd rotation crushing blade 28 are comprised integrally, and the 1st rotation crushing blade 26 and the 3rd rotation crushing blade are comprised. The blade 28 and the fifth rotary crushing blade 30 are integrated with the second fixed crushing blade 27 and the fourth fixed crushing blade 29 in between.

  In addition, the attachment of each crushing blade integrated into the housing 31 as described above is performed by fitting the tab 38 of the second fixed crushing blade 27 and the tab 44a of the fourth fixed crushing blade 29 into the vertical groove 31b of the housing 31. Thus, the second fixed crushing blade 27 and the fourth fixed crushing blade 29 are held by the housing 31 so as not to rotate.

  Then, by holding the holding metal 31d in the vertical groove 31b and fixing with a screw (not shown), the crushing blades are held in the up-and-down direction impossible by the holding metal 31d and the flange portion 31a. Thereby, the 1st rotation crushing blade 26, the 3rd rotation crushing blade 28, and the 5th rotation crushing blade 30 become rotatable with respect to the housing 31.

  As shown in FIG. 6, the first rotary crushing blade 26, the second fixed crushing blade 27, the third rotary crushing blade 28, the fourth fixed crushing blade 29, and the fifth rotary crushing blade 30 have almost no vertical spacing. The dimensions are set so as to overlap with each other so that the crushed raw garbage does not enter the upper and lower gaps of the crushing blade and remain in the crushing unit 4.

It hits.

  8A and 8B show the flow of water in the water contact portion 12, FIG. 8A is a front sectional view of the main part, and FIG. 8B is a side sectional view of the main part. In the lid 8, the water that flows down by hitting the water contact portion 12 flows laterally by the step portion 12 a and flows into the bottom portion 11 as shown in FIGS. 8A and 8B.

  Further, as shown in FIG. 8 (b), a part of the water hitting the water contact portion 12 flows upward along the slope of the water contact portion 12, and then flows horizontally as shown in FIG. 8 (a). Flows in the direction and into the bottom 11. And the water which flowed into the bottom part 11 is dripped from the several water supply port 13 which penetrated the bottom part 11, and is supplied in the hopper 3. FIG.

  The lid 8 closes the upper opening of the water reservoir 11a with the upper lid 8b. Thereby, a user does not recognize the amount of water at the time of water supply. In addition, the water hitting the water pad 12 is prevented from scattering to the sink S.

  Here, about 8 L / min of water is supplied to the lid 8, but the number and size of the first water supply port 13 a, the second water supply port 13 b, and the third water supply port 13 c are different from each other. When water of about 8 L / min is supplied to the body 8, some water is set to be stored in the water storage part 11a.

  Note that, in the lid body 8 that does not include the water contact portion 12, the water discharged from the supply port 18 hits the inner peripheral surface of the water storage portion 11 a facing the supply port 18 and flows along the inner peripheral surface. And when there exists a convex part in the internal peripheral surface of the water storage part 11a, it contacts a convex part and flows into the bottom part 11. FIG. Then, the amount of water that flows into the portion close to the convex portion increases, and the amount of water dripped from the water supply port 13 near the convex portion increases.

  In addition, in the lid body 8 that includes the water pad 12 but does not include the stepped portion 12a, the water that hits the water pad 12 flows down as it is and flows into a portion near the water pad 12. The amount of water increases, and the amount of water dripping from the water supply port 13 close to the water pad 12 increases.

  On the other hand, in the lid body 8 provided with the water contact portion 12 and the step portion 12a, the water discharged from the supply port 18 is diffused, and water is allowed to flow substantially uniformly throughout the bottom portion 11 to store water in the water storage portion 11a. can do. Thereby, water can be supplied into the housing 31 from each water supply port 13 substantially equally.

  FIG. 9 is an explanatory view showing the flow of water from the lid body 8, and next, the flow of water from each water supply port 13 will be described. The plurality of water supply ports 13 are arranged radially from the vicinity of the center of the bottom portion 11 of the water storage portion 11a to the outer peripheral side, so that water can be supplied to the entire inside of the housing 31 of the crushing unit 4 in the hopper 3.

  In this example, among the plurality of water supply ports 13, the first water supply port 13 a arranged on the outer peripheral side of the water storage portion 11 a is inclined outward from the upper surface to the lower surface of the bottom portion 11 on the side surface on the outer peripheral side. The guiding slope 15 is formed.

  Thereby, the water passing through the first water supply port 13 a flows along the guide slope 15 toward the inner peripheral surface of the housing 31, and mainly flows along the inner peripheral surface of the housing 31. Therefore, the garbage attached to the inner peripheral surface of the housing 31 and the garbage attached to the inner peripheral surface of the housing 31 in the crushing process to be described later can be actively dropped downward by the flow of water.

  The second water supply port 13 b has an annular protrusion 16 formed on the lower surface side of the bottom 11, and the third water supply port 13 c has an angular ring-shaped protrusion 17 formed on the lower surface side of the bottom 11. Here, if the opening of the second water supply port 13b and the third water supply port 13c is the same height as the lower surface of the bottom portion 11, the water passing through the second water supply port 13b or the third water supply port 13c is It does not fall directly below, but flows laterally along the bottom surface of the bottom 11.

  On the other hand, by providing the protrusion 16 on the lower surface side of the second water supply port 13b and providing the protrusion 17 on the lower surface side of the third water supply port 13c, the second water supply port 13b and the third water supply port 13b are provided. The water that has passed through the water supply port 13c falls directly below. Thereby, water can be directly supplied to the vicinity of the center in the housing 31.

  The control unit 25 shown in FIG. 1 detects that the lid 8 has been attached to the charging opening 7 with the lid switch 24, and when a certain time has passed since the electromagnetic valve 23 was opened and water supply was started. Then, rotational driving of the motor 6 is started.

  Specifically, a rotation operation that repeats the forward rotation and the reverse rotation operation is performed every few seconds, for example, every 5 seconds. The rotation speed of the motor 6 is set to about 100 rpm, and the generation of noise and vibration is suppressed.

  Next, the crushing process will be described. When the motor 6 rotates, in the crushing unit 4, the first rotary crushing blade 26, the third rotary crushing blade 28, and the fifth rotary crushing blade 30 rotate together. In contrast, the second fixed crushing blade 27 and the fourth fixed crushing blade 29 do not rotate.

  Thereby, the garbage thrown into the hopper 3 is stirred by the stirring arm 33 of the first rotary crushing blade 26 and roughly crushed in cooperation with the arm 36 of the lower second fixed crushing blade 27. The crushed garbage is sent between the arms 40 of the third rotary crushing blade 28.

  Here, the stirring arm 33 of the first rotary crushing blade 26 is formed with a pushing surface 34a. Since the pushing surface 34a is a slope inclined in the direction in which the upper end protrudes with respect to the lower end, the garbage is subjected to a force for pushing downward by the rotating operation of the first rotary crushing blade 26.

  Thereby, the uptake | capture property of the garbage in an initial crushing stage improves. In particular, it is possible to improve the uptake of garbage, such as grapefruit peel, which is relatively large, light and curved, and the crushing process can be completed within a predetermined processing time. Can prevent delays.

  The garbage sent between the arms 40 of the third rotary crushing blade 28 is rotated between the comb tooth portion 40a of the arm 40 and the arm 43 of the lower fourth fixed crushing blade 29 by the rotation of the third rotary crushing blade 28. Finely crushed by meshing with the comb teeth 43a.

  Here, the 4th fixed crushing blade 29 is provided with the arm 43b which does not provide the comb-tooth part 43a in the some arm 43, By the rotation of the 3rd crushing blade 28, the comb-tooth part 43a is provided. When the non-arm 43b is located between the arms 40 of the third rotary crushing blade 28, a large space is formed in the circumferential direction. As a result, even large garbage such as a block can enter between the arms 40 of the third rotary crushing blade 28, and the rotation of the third rotary crushing blade 28 results in the comb teeth 40 a of the third rotary crushing blade 28 and the fourth fixed portion. It is finely crushed by meshing with the comb teeth 43a of the other arm 43 of the crushing blade 29.

  Thereby, the garbage which mixed various sizes can be crushed with the combination of a small number of fixed crushing blades and rotary crushing blades.

  The raw garbage crushed by the cooperation of the third rotary crushing blade 28 and the fourth fixed crushing blade 29 is discharged from the slit 46 by the cooperation of each arm 43 of the fourth fixed crushing blade 29 and the fifth rotary crushing blade 30. Is done.

  That is, when garbage comes into contact with the upper arm 43 by the rotation of the fifth rotary crushing blade 30, the garbage is pressed against the slit 46 and crushed by the edge of the opening edge on the upper surface side of the slit 46. Fall down the street.

  As described above, the slit 46 has a stepped portion, and the opening on the bottom surface side is larger than the opening on the upper surface side. Therefore, the raw garbage pushed into the slit 46 passes through the step portion and moves to a wide portion, and falls downward without being clogged by the slit 46.

  Here, water is supplied through the lid 8 during the crushing process, but the water is supplied almost uniformly from the peripheral surface of the housing 31 to the center. The garbage attached to the blade can be efficiently flowed downward. Thereby, the processing time until the garbage is crushed and the crushed garbage is discharged can be shortened.

  In the garbage processing apparatus 1, for example, after the motor 6 is rotationally driven for a certain time, the control unit 25 stops the driving of the motor 6. The driving time of the motor 6 is set in consideration of the time required for crushing a standard amount of garbage thrown into the hopper 3 and discharging it from the drain pipe connection port 21.

  Then, after the drive of the motor 6 is stopped, the electromagnetic valve 23 is closed after a predetermined time has elapsed, and the supply of water to the lid 8 is stopped.

  In addition, the magnitude | size and number of each water supply port 13 are not restricted to the example shown in FIG. Further, in this example, the water supply to the inside of the lid body 8 is configured to be performed from one place, but two sets of the piping 10 and the supply port 9 of the hopper 3 and the supply port 18 of the lid body 8 are provided, It is good also as a structure which supplies water from two places. Even in this configuration, both supply ports 18 are arranged to face the water pad 12 so that water is applied to the water pad 12 and then stored.

  Further, the garbage disposal apparatus may be a hammer mill type or a chain mill type other than the grinder type.

  The present invention is installed in a kitchen or the like of a building and can improve the convenience of processing garbage.
