  The input cylinder part 21 is open at the upper and lower ends, and is provided with a connection part 24 to the input opening part 9 of the upper unit 5 at the upper end part. The connecting portion 24 is configured to be fitted with the insertion cylinder portion 21 and the insertion opening, and an O-ring or the like (not shown) is fitted for waterproofing. Here, in the connection part 24, the insertion part length of the site | part in which the injection | throwing-in cylinder part 21 and the injection | throwing-in opening part 9 fit is given a clearance. Moreover, it is good to display a scale so that the minimum required overlap can be seen visually.

  Further, a drain port 25 is provided on the inner peripheral surface on the lower end side of the charging cylinder part 21. A filter 26 is attached to the entrance of the drain port 25. The filter 26 has, for example, a semi-cylindrical shape covering the entrance of the drain port 25, has a function of capturing garbage and passing moisture, and is detachable so that it can be replaced.

  The bottom cover 22 is attached to the lower end of the insertion cylinder part 21 so that opening and closing is possible. The bottom lid 22 includes a disc-shaped lid portion 27 that fits into the opening at the lower end of the charging cylinder portion 21, a shaft portion 28 that protrudes from a part of the outer periphery of the lid portion 27, and a shaft portion 28 in the lid portion 27. And a pressing portion 29 formed at a position facing the.

  The shaft portion 28 of the bottom cover 22 is formed outside the outer periphery of the cover portion 27, and rotates with the shaft portion 28 as a fulcrum, so that the bottom cover 22 opens and closes the opening at the lower end of the input cylinder portion 21 with the cover portion 27. .

  FIG. 5 shows a main configuration of the bottom cover 22. The lid portion 27 of the bottom lid 22 has a configuration in which a disc-shaped first lid portion 27a and a second lid portion 27b having a larger diameter than the first lid portion 27a are integrated, and a step is formed on the outer periphery. And convex. Moreover, the groove | channel 27c is formed in the outer peripheral part over the circumferential direction, and the sealing material 30 is engage | inserted by the groove | channel 27c.

  The sealing material 30 has a tapered surface 30a on the outer periphery, and projects a predetermined amount from the outer periphery of the first lid portion 27a and the outer periphery of the second lid portion 27b.

  A tapered surface 31 is formed at a portion where the lid portion 27 fits in the opening at the lower end of the charging cylinder portion 21 where the bottom lid 22 opens and closes. The tapered surface 31 of the charging cylinder portion 21 has an inclination equivalent to the tapered surface 30 a of the sealing material 30.

  The bottom cover 22 opens and closes by rotating around the shaft portion 28 as a fulcrum. For this reason, the first lid portion 27 a has a diameter that can secure a clearance with which the bottom lid 22 can be opened and closed with respect to the inner diameter of the input cylinder portion 21. 5A, when the bottom lid 22 is closed, the first lid portion 27a and the second lid portion 27a of the sealing material 30 are attached so that the sealing material 30 can be in close contact with the tapered surface 31a of the charging cylinder portion 21. The amount of protrusion from the lid portion 27b is set.

  As shown in FIG. 5A, when the bottom lid 22 is closed, the portion where the sealing material 30 is exposed is the clearance between the first lid portion 27a and the charging cylinder portion 21, and the second lid. This is a clearance portion between the portion 27 b and the charging cylinder portion 21.

  For this reason, there are few parts which touch moisture etc. directly and degradation is prevented. Further, even if solids such as a spoon and a fork are mistakenly inserted, the sealing material 30 is not directly damaged unless it is smaller than the clearance between the lid portion and the charging cylinder portion 21.

  Moreover, since the contact area of the sealing material 30 and the injection | throwing-in cylinder part 21 can be taken widely, adhesiveness improves.

  Further, as shown in FIG. 5B, when the shaft portion 28 is opened and closed with the fulcrum as a fulcrum, the sealing material 30 and the tapered surface 31 of the charging cylinder portion 21 are opened and closed by abutting the surfaces. Thereby, the bottom cover 22 can be opened and closed with a light force.

  In addition, you may give the coating corresponding to a water | moisture content etc. to the exposed part of the sealing material 30 when the bottom cover 22 is closed. Further, a ring or the like made of a material different from that of the sealing material 30 may be fitted to the exposed portion of the sealing material 30 when the bottom cover 22 is closed.

  Furthermore, O-rings having different diameters may be overlapped to form a tapered surface.

  Returning to FIG. 2, the bottom lid 22 has an inclined surface 27 d formed on the top surface of the lid portion 27. The inclined surface 27d is inclined so as to descend toward the drain port 25. Here, when the bottom cover 22 is closed, the lowermost end of the inclined surface 27 d is set to a height that is substantially equal to or slightly above the lower end of the drainage port 25.

  The bottom lid 22 is provided with a push-up convex portion 32 on the lower surface in order to perform an operation of being closed by being pushed by the rotary blade by a rotary motion of the rotary blade described later.

  The push-up convex portion 32 has a shape along the locus of the tip of the rotor blade and a curved surface slightly larger than the locus of the rotor blade when the closing cylinder portion 21 is closed by the bottom cover 22.

  The opening / closing mechanism 23 includes a first lock cam 33 that comes into contact with the link 14 of the upper unit 5, a second lock cam 34 that performs locking and opening assistance in a closed state of the bottom cover 22, a first lock cam 33, and a second lock cam 33. A drive shaft 35 for connecting the lock cam 34 and a drive unit 36 for driving the drive shaft 35.

  The first lock cam 33 has a cam surface eccentric with respect to the drive shaft 35. The first lock cam 33 abuts on the cam abutment surface 14b of the link 14, and the drive shaft 35 is driven to unlock the lid 11.

  As shown in FIG. 6, the second lock cam 34 includes a pushing surface 34 a and a pushing surface 34 b with the drive shaft 35 interposed therebetween.

  The push-up surface 34a of the second lock cam 34 is composed of an upward slope and a plane continuous from the slope, and the second lock cam 34 rotates in a predetermined direction so that the push portion 29 of the bottom lid 22 has a lower side. The bottom lid 22 is pushed up.

  Further, the pressing surface 34b of the second lock cam 34 is configured by a downward slope, and the pressing surface 34b abuts against the pressing portion 29 of the bottom lid 22 from above by the second locking cam 34 rotating in the other direction. Then, the bottom lid 22 is pushed down.

  Here, by setting the point of action of the force by the second lock cam 34 to the bottom cover 22 to be opposite to the shaft portion 28, the bottom cover 22 can be reliably locked when locked in the closed state.

  The drive shaft 35 is supported by the lower unit 6 by a bracket 37, and the first lock cam 33 is attached to the upper end side, and the second lock cam 34 is attached to the lower end side.

  Further, the bracket 37 is attached with a stepping motor 36a and a gear 36b constituting the drive unit 36, and a driving force is transmitted to the drive shaft 35 from the stepping motor 36a through the gear 36b and the like.

  Further, a magnet 38 is attached to the drive shaft 35 in order to detect the orientation of the first lock cam 33 and the second lock cam 34. A cam position detection sensor 39 that detects the magnet 38 is attached to the bracket 37.

  Now, the upper end of the drive shaft 35 is supported by the shaft support portion 15 of the upper unit 5, and the slide lock 13 is moved via the link 14 by the rotation of the first lock cam 33.

  Since the first lock cam 33 and the second lock cam 34 are attached to the drive shaft 35, the first lock cam 33 and the second lock cam 34 are rotated in conjunction with each other by receiving the drive force of the drive unit 36. Thereby, a series of operations of locking and unlocking the bottom lid 22 and unlocking the lid 11 is performed by one drive source.

<Configuration of rotor blade>
FIG. 7 is a perspective view illustrating a configuration example of the rotary blade 44, and FIG. 8 is a cross-sectional view illustrating a configuration example of the rotary blade 44. FIG. 9 is a cross-sectional view of the processing vessel 42 cut along a plane along the axial direction of the rotary blade 44.

  The rotary blade 44 includes a hollow shaft portion 45 and a hollow blade portion 46 which is formed continuously with the shaft portion 45. The inside of the shaft portion 45 communicates with the inside of the wing portion 46.

  As shown in FIG. 9, one end portion of the shaft portion 45 is rotatably inserted into one bearing portion 42a of the processing vessel 42, and the other end portion is rotatably inserted into the other bearing portion 42b of the processing vessel 42. The rotary blade 44 is rotatable with respect to the processing container 42.

  The wing portion 46 extends in a direction intersecting with the axial direction of the shaft portion 45, and a plurality of groove portions 47 are formed at the tip thereof to form a comb shape.

  In the wing portion 46, a plurality of slits (spout ports) 48 are formed on one inclined surface 46a. The slit 48 is arranged along the slope 46 a in parallel with the axial direction of the rotary blade 44.

  Each slit 48 extends along the wing portion 46 and communicates between the inside and outside of the rotary wing 44. As shown in FIG. An intrusion prevention unit 46b for dust or dry dust is formed. Thus, it is configured that it is difficult for dust to enter the inside of the wing portion 46 through the slit 48 from the vertical direction with respect to the wing portion 46. In order to form the intrusion prevention part 46b, the slope 46a is made thick, and the center 46c of the wing part 46 is offset with respect to the center 45c of the shaft part 45 so that the slope 46a is inclined. is there.

Here, the blade portion 46 of the rotary blade 44 is formed such that a tip of the blade portion 46 opens with respect to the circumferential surface of the stirring / drying space 43 of the processing vessel 42. As shown in FIG. 10, the wiper 50 protrudes from the tip of the wing 46 and comes into contact with the inner peripheral surface of the processing container 42.

  The rotary blade 44 is configured by combining the first member and the second member, and the wiper 50 is sandwiched between the dividing surfaces of the blade portion 46, and is positioned and fixed by screws and bosses (not shown).

<Configuration of processing container>
As shown in FIG. 1, the processing container 42 includes an origin position detection sensor 51 a that detects the position of the rotary blade 44 and a bottom lid push-up position detection sensor 51 b. FIG. 1 shows a state where the rotary blade 44 is at the origin position. In this example, the origin position of the rotary blade 44 is a state in which the blade portion 46 is vertically downward. As will be described later, when the rotary blade 44 is rotated to the position detected by the bottom lid push-up position detection sensor 51b with the bottom lid 22 of the lower unit 6 open, the bottom lid 22 is pushed up by the rotary blade 44 and The operation of closing the lid 22 is performed.

  The processing container 42 includes a PTC heater 52 (heating means). The PTC heater 52 is a heater having a positive thermistor characteristic. When the temperature rises, the resistance value rises. As a result, the consumed current is controlled and the temperature rise is moderated. The temperature reaches a saturation region and becomes stable, and self-temperature control is performed.

  As described above, the PTC heater 52 has a characteristic that the consumption current decreases as the heater temperature rises, and then the current consumption is stabilized at a low value when the temperature reaches a certain temperature saturation region. There is an advantage that power consumption can be saved and an abnormal increase in the temperature of the heating element can be prevented.

  The PTC heater 52 is affixed to the outer periphery near the bottom of the processing container 42, covered with a heat insulating material, and the inside of the processing container 42 is heated.

  FIG. 11 and FIG. 12 are perspective views showing a configuration example of the processing container 42. The processing container 42 is provided with a discharge port 53 at a front position. The discharge port 53 is, for example, a rectangular opening. The processing container 42 includes guide ribs 54 on the left and right sides of the discharge port 53.

  The operation lever 60 includes a magnet 60b. Further, the processing container 42 includes a discharge opening / closing detection sensor 61. The discharge opening / closing detection sensor 61 is a magnet sensor, and detects the magnet 60b when the operation lever 60 is operated and the plate 60a is in a position where it enters the locking hole 57 of the guide rib 54. Accordingly, it can be detected that the plate 60a of the operation lever 60 enters the locking hole 57 of the guide rib 54 and the cover unit 58 is in the locked state with the discharge port 53 closed.

  Returning to FIG. 1, the cover unit 58 includes a plurality of sets of cutters (crushing means) 62 on the back surface side. Each cutter 62 protrudes into the processing container 42 from the back surface of the cover unit 58 at the position where the discharge port 53 is closed, and the position in the circumferential direction and the position in the axial direction are shifted from each other.

  Each cutter 62 is formed in a fan shape, and a blade 62a is formed on one side edge thereof. Further, a shaft portion (not shown) is provided on one end side of the blade portion 62a, and is urged in a direction in which the blade portion 62a protrudes by a spring member (not shown). As a result, when an excessive force is applied to the cutter 62, the shaft portion can be rotated around the fulcrum and can be retracted from the inner surface of the processing container 42 into the cover unit 58.

The discharge plate 64 is attached between the guide ribs 54 and extends obliquely downward from the vicinity of the lower end of the discharge port 53 to cover a part of the lower side of the discharge port 53.

<Rotary blade drive mechanism>
FIG. 15 is an explanatory diagram showing the configuration of the driving mechanism and the air blowing mechanism of the rotary blade. The rotating blade 44 (not shown in FIG. 15) has a spur gear 65 attached to one shaft portion 45 protruding from the processing vessel 42. A counter gear 66 that meshes with a flat gear 65 is attached to the processing container 42, and a small gear 68 that is attached to a motor 67 is engaged with the counter gear 66.

  When the motor 67 is rotated, a driving force is transmitted to the rotary blade 44 through the small gear 68, the counter gear 66, and the flat gear 65, and the rotary blade 44 rotates about the shaft portion 45 as a central axis.

<Blower mechanism for rotor blade>
A fan (drying means) 69 is attached to the cover 41. The fan 69 is a so-called sirocco fan, and the exhaust port 69a is connected to one end of the shaft portion 45 of the rotary blade 44 (not shown in FIG. 15) through a duct 70. Here, the connection between the duct 70 and the shaft portion 45 has a configuration in which the shaft portion 45 is rotatable with respect to the duct 70 while maintaining airtightness.

<Intake mechanism>
FIG. 16 is a perspective view showing an intake mechanism of the cover. The cover 41 includes an intake port 71 as shown in FIG. The cover 41 has airtightness and sucks outside air from the intake port 71. The intake port 71 is provided with a check valve 72 as shown in FIG. For example, the check valve 72 is opened when the pressure in the cover 41 becomes negative due to intake air by driving the fan 69 shown in FIG. Further, by stopping the driving of the fan 69, when the pressure difference between the inside and the outside of the cover 41 becomes zero or positive pressure, the fan 69 is closed by a spring or its own weight.

  As a result, the check valve 72 is opened at the intake port 71 by the intake air generated by driving the fan 69 and intakes the outside air. As a result, the fan 69 blows air into the rotor blades 44.

  When the driving of the fan 69 is stopped, the check valve 72 is closed to prevent the air inside the cover 41 from leaking out of the cover through the air inlet 71.

As shown in FIG. 11, the processing container 42 has an exhaust port 74 formed in the upper portion, and the filter unit 75 shown in FIG. 17 is attached to the exhaust port 74. In addition, a check valve unit 76 is attached to the upper portion of the processing container 42 along with the filter unit 75.

  FIG. 18 is an explanatory diagram showing the configuration of the filter unit. The filter unit 75 includes a cover 77, a filter 78, and a brush 79. The cover 77 includes a first joint 80 attached to the exhaust port 74 of the processing container 42, a claw 81 formed in the first joint 80, and screwing formed in a portion facing the claw 81. Part 82 is provided. Further, a second joint portion 84 attached to the intake port 83 of the check valve unit 76 is provided.

  Here, the 2nd junction part 84 is made to incline from a perpendicular surface with respect to the 1st junction part 80 in the direction which an upper end side protrudes with respect to a lower end side.

  The filter 78 is provided between the first joint 80 and the second joint 84. The brush 79 is attached to the cover 77 so as to be movable along the surface of the filter 78. An operating rod 79a is attached to the brush 79, and the filter 78 can be cleaned by moving the brush 79 along the surface of the filter 78 by operating the operating rod 79a from the outside of the cover 77. Here, in order to make the degree of contamination of the filter 78 visible from the outside of the cover 77, for example, the cover 77 may be formed of a transparent resin.

  When the filter unit 75 fits the claw portion 81 of the cover 77 into the locking hole 85 of the processing container 42 shown in FIG. 11 and fixes the screwing portion 82 to the processing container 42 with a screw (not shown), the first joint 80 is Close contact with the exhaust port 74. Further, since the second joint portion 84 is formed with a downward slope, the second joint portion 84 is in close contact with the intake port 83 of the check valve unit 76 by a force pressing the first joint portion 80 against the exhaust port 74.

  Accordingly, the filter unit 75 can be attached to the processing container 42 and the check valve unit 76 in a state where the portion on the intake side and the portion on the exhaust side are in close contact with each other, and the exhaust is prevented from leaking to the outside.

  Further, since the airtightness can be maintained by tightening the screws, the replacement is easy, and the filter 78 that can no longer perform its intended function even by cleaning with the brush 79 is easily replaced together with the filter unit 75. Therefore, the performance of the entire apparatus can be maintained.

  The check valve unit 76 includes a solenoid valve (not shown) and the like, and is configured to open and close the exhaust passage. As shown in FIGS. 15 and 17, the exhaust port 74 of the processing container 42 is connected to a drain pipe downstream from the drain trap 87 by a duct 86 through a filter unit 75 and a check valve unit 76. If the drainage water flows backward due to clogging of the drainage pipe or the like, the inflow of water is detected by a sensor, and the check valve is closed to prevent the backflow of drainage into the filter unit 75 and further into the processing container 42.

  In addition, as shown in FIG. 11, when the drain cock 42e for draining water is provided in the lower part of the processing container 42, when the water more than processing capacity enters into the processing container 42, this can be discharged | emitted outside. It is. Further, by making a part of the processing container 42 transparent, it is possible to visually confirm that, for example, water has accumulated.

<Processing container division mechanism>
The processing container 42 is configured by combining a first case 42c and a second case 42d as shown in FIG. The first case 42c and the second case 42d are integrated so as to be disassembled by, for example, screwing, and the divided surfaces of the first case 42c and the second case 42d are the bearing portions 42a and 42b of the rotor blade 44.

  Accordingly, as shown in FIG. 19, when the first case 42c is removed, the rotor blades 44 can be removed and replaced. Here, the lower unit 6 is provided in the second case 42d on the back side of the apparatus, and remains on the apparatus main body side even when the first case 42a is removed. That is, as shown in FIG. 1, the lower unit 6 is connected to the upper unit 5 attached to the sink 2, so that when the processing container 42 is disassembled, the lower unit 6 remains on the apparatus main body side. Disassembly is easy.

<Control configuration of garbage disposal device>
FIG. 20 is a control block diagram of the garbage processing apparatus. The control device 91 includes a system controller (control means) 92. The system controller 92 is connected to the above-described top lid detection sensor 19, cam position detection sensor 39, origin position detection sensor 51a, bottom lid push-up position detection sensor 51b, discharge opening / closing detection sensor 61, and the like.

  The system controller 92 detects from the output of the upper lid detection sensor 19 whether the lid 11 is in a locked state by closing the closing opening 9. Further, from the output of the cam position detection sensor 39, the positions of the first lock cam 33 that unlocks the lid 11 and the second lock cam 34 that locks and unlocks the bottom lid 22 are detected. Further, the position of the rotary blade 44 is detected from the outputs of the origin position detection sensor 51a and the bottom lid push-up position detection sensor 51b, and the opening / closing of the cover unit 58 is detected from the output of the discharge port opening / closing detection sensor 61.

  The system controller 92 is connected to a stepping motor 36a, a motor 67, a PTC heater 52, and a fan motor that drives the fan 69. The system controller rotates and stops the rotation of the fan motor that drives the stepping motor 36a, the motor 67, and the fan 69 according to a predetermined program from the output of each sensor. Further, the PTC heater 52 is turned on and off. Furthermore, a stepping motor or the like that drives the check valve of the check valve unit 76 may be connected to the system controller 92.

<Garbage input operation>
First, in the state where the lid 11 is open, the bottom lid 22 closes the lower end of the charging cylinder portion 21 as shown in FIG. As shown in FIG. 2, the pressing portion 29 of the bottom lid 22 is pushed up by the pushing portion 34 a of the second lock cam 34.

  As a result, as shown in FIG. 5, the sealing material 30 attached to the bottom cover 22 is in a state where the tapered surface 30 a is pressed against the tapered surface 31 of the input cylinder part 21.

  When the garbage is thrown from the throwing opening portion 9 communicating with the throwing cylinder portion 21, the thrown garbage is collected on the bottom cover 22. As described above, since the sealing material 30 of the bottom cover 22 is pressed against the tapered surface 31 of the input cylinder part 21, leakage of moisture contained in raw garbage from the bottom cover 22 is suppressed.

  And since the inclined surface 27d is formed in the upper surface of the bottom cover 22, a water | moisture content is drained from the drain outlet 25 to the upstream of a drain trap along the inclined surface 27d. Here, since the filter 26 is attached to the drain port 25, the garbage does not pass through the filter 26, and moisture is drained to the drain port 25.

  As shown in FIG. 5A, when the bottom cover 22 is closed, the portion where the sealing material 30 is exposed on the input opening 9 side is the clearance between the cover part 27 of the bottom cover 22 and the input cylinder part 21. Part. For this reason, even if a fork etc. are accidentally thrown in, the sealing material 30 is not damaged.

  FIG. 21 is a flowchart showing a flow of processing at the time of throwing in garbage. In order to process the garbage thrown into the loading opening 9 with the garbage processing apparatus 1, the closing opening 9 is first closed with the lid 11 (step A1).

  When the lid body 11 is fitted into the closing opening 9 and rotated in a predetermined direction, the locking claw 16 of the slide lock 13 is fitted into the locking hole 11b of the lid body 11, and the rotation of the lid body 11 is restricted. Moreover, the rib 11a of the cover body 11 fits into the rib 10a of the input opening 9, and restricts the upward movement of the cover body 11. As a result, the lid 11 is locked in the closing opening 9 in the closed state.

  When the locking claw 16 of the slide lock 13 is fitted into the locking hole 11 b of the lid body 11, the upper lid detection sensor 19 detects the magnet 18 of the lid body 11. As a result, the system controller 92 detects that the lid 11 is fitted in the opening insertion portion 9 and locked in the closed state (step A2).

  When the upper lid detection sensor 19 detects the lock of the lid 11, the system controller 92 detects the position of the rotary blade 44 from the output of the origin position detection sensor 51 a. That is, when the rotor blade 44 is rotating, when the origin position detection sensor 51a detects the rotor blade 44, the rotation of the motor 67 is stopped and the rotor blade 44 is stopped at the origin position (step A3).

  Further, the system controller 92 stops the rotation of the fan motor that drives the fan 69. In this example, when the rotation of the fan 69 is stopped, the check valve 72 is closed due to the pressure between the inside of the cover 41 and the outside. Further, the check valve of the check valve unit 76 is closed by the stepping motor, and the PTC heater 52 is stopped (step A4).

  When the upper cover detection sensor 19 detects the lock of the lid 11, the system controller 92 starts driving the stepping motor 36 a after a predetermined time has elapsed. Here, the system controller 92 performs the processes of Step A3 and Step A4 described above until a predetermined time elapses after the upper lid detection sensor 19 detects the lock of the lid 11.

  FIG. 22 is an explanatory view showing the operation of the lock cam for locking and unlocking the bottom lid, with the upper row showing the lid (upper lid) and the lower row showing the lock mechanism of the bottom lid. FIG. 22A shows a state where the first lock cam 33 and the second lock cam 34 are at the origin position. In the state where the first lock cam 33 is at the origin position, the locking claw 16 of the slide lock 13 protrudes from the closing opening 9. Further, in the state where the second lock cam 34 is at the origin position, the push-up portion 34a is in contact with the bottom lid 22 and pushed up.

  When the system controller 92 detects the lock of the lid 11 by the upper lid detection sensor 19 and a predetermined time has elapsed, the system controller 92 drives the stepping motor 36a to rotate the second lock cam 34 in the direction of arrow a to open the bottom lid 22 ( Step A5).

  FIG. 22B shows a state in which the second lock cam 34 is rotated 90 degrees in the direction of arrow a from the origin position. When the second lock cam 34 is rotated 90 degrees in the direction of the arrow a from the origin position, the push-up portion 34a gradually moves away from the bottom lid 22, but in this state, the bottom lid 22 is still held.

  Here, since the second lock cam 34 and the first lock cam 33 are coupled by the drive shaft 35 as shown in FIG. 2, when the second lock cam 34 is rotated, the first lock cam 33 is also rotated in conjunction with it. . When the first lock cam 33 rotates 90 degrees in the direction of arrow a from the origin position, the first lock cam 33 moves away from the link 14. In this state, the slide lock 13 does not move.

  FIG. 22C shows a state in which the second lock cam 34 is rotated 130 degrees in the direction of arrow a from the origin position. When the second lock cam 34 is rotated 130 degrees in the direction of arrow a from the origin position, the push-up portion 34a is separated from the bottom lid 22. Thereby, the lock | rock in the closed state of the bottom cover 22 by the 2nd lock cam 34 is cancelled | released.

  Since the bottom lid 22 opens in the vertical direction, when the lock by the second lock cam 34 is released, the bottom lid 22 opens with the shaft portion 28 as a fulcrum by its own weight and the weight of garbage. FIG. 23 shows a state where the bottom cover 22 is opened. Thereby, the garbage on the bottom cover 22 is put into the processing container 42.

  At this time, since the rotary blade 44 is stopped at the origin position, the bottom lid 22 does not come into contact with the rotary blade 44 during the opening operation of the bottom lid 22.

  Normally, the bottom cover 22 is automatically opened by its own weight or the like when the lock by the second lock cam 34 is released. However, it is conceivable that the bottom cover 22 is not opened by its own weight due to the sticking of the sealing material 30 or the like. Therefore, the bottom lid 22 is forcibly opened by the second lock cam 34.

  FIG. 22D shows a state in which the second lock cam 34 is rotated 180 degrees from the origin position in the direction of arrow a. When the second lock cam 34 is rotated 180 degrees from the origin position in the direction of arrow a, the pressing portion 34b presses the pressing portion 29 of the bottom lid 22 from above. As a result, a force for forcibly opening the bottom lid 22 is applied, and the sealing material 30 can be forcibly opened even if it is not opened by its own weight due to sticking or the like (step A6).

  When the system controller 92 rotates the second lock cam 34 and the first lock cam 33 180 degrees in the direction of arrow a from the origin position, the system controller 92 stops driving the stepping motor 36a. Here, the rotation angle of the second lock cam 34 and the first lock cam 33 is controlled by the rotation phase of the stepping motor 36a after the origin position is detected by the cam position detection sensor 39.

  Note that while the first lock cam 33 is rotated 180 degrees from the origin position in the direction of arrow a, the first lock cam 33 is away from the link 14 and the slide lock 13 does not move. Thereby, the cover 11 remains locked in the closed state. For this reason, the lid 11 cannot be opened with the bottom lid 22 open, and the backflow of odor from the processing container 42 and the inflow of moisture into the processing container 42 are prevented.

  Now, the time from when the top lid detection sensor 19 detects the lock of the lid 11 to when the stepping motor 36a is started and when the bottom lid 22 is opened is set to several seconds, for example, about 5 seconds.

  This is because the garbage thrown into the loading opening 9 is considered to contain moisture, so that even after the lid 11 is closed, the garbage is cut off by waiting on the bottom lid 22 before the processing container. This is because the battery is put into 42.

  When the system controller 92 stops the driving of the stepping motor 36a by rotating the second lock cam 34 and the first lock cam 33 180 degrees in the direction of arrow a from the origin position, the rotor 67 is moved by the motor 67 as shown in FIG. In the direction of arrow c (step A7).

  When the rotor blade 44 at the origin position is rotated in the direction of the arrow c with the bottom cover 22 opened, the bottom cover 22 exists in the rotation locus of the rotor blade 44, so that the blade portion 46 of the rotor blade 44 is at the bottom. It contacts the push-up convex part 32 of the lid 22. Further, as shown in FIG. 25, when the rotary blade 44 is rotated until it is detected by the bottom lid push-up detection sensor 51b, the rotary blade 44 pushes up the bottom lid 22 and the bottom lid 22 rotates with the shaft portion 28 as a fulcrum. Close with movement.

  When the bottom lid push-up detection sensor 51b detects the rotary blade 44, the system controller 92 stops the rotation of the motor 67. As a result, the bottom lid 22 closes the charging cylinder portion 21 while being supported by the rotating blades 44.

  Here, if the bottom cover push-up detection sensor 51b does not detect the rotating blade 44 even after a predetermined time has elapsed since the rotation of the motor 67 is started, the system controller 92 reverses the motor 67 by a predetermined amount to rotate the rotating blade. Return 44 to the origin position or a little beyond the origin position, and retry. If the bottom lid push-up detection sensor 51b does not detect the rotor blade 44 even after a plurality of retries, an alarm is generated and an error occurs.

  At this time, since the bottom cover 22 is considered to be open, the system controller 92 keeps the cover 11 locked in the closed state and closes the check valve of the check valve unit 76. As it is, the diffusion of odor and the intrusion of moisture into the processing container 42 are prevented.

  As shown in FIG. 1, the sink 2 has a drain port 8 formed in parallel with the input opening 9, and the drain port 8 is not blocked by the lid 11, so the lid 11 is closed. Even so, it can function as a normal sink.

  When the bottom lid push-up detection sensor 51b detects the rotating blade 44 and stops the rotation of the motor 67, the system controller 92 rotates the stepping motor 36a, and the second lock cam 34 and the first lock cam 33 are moved to the position shown in FIG. From the state of d), it is rotated in the direction of arrow b.

  When the second lock cam 34 rotates in the direction of the arrow b to the state shown in FIG. 22B, the push-up portion 34 a contacts the pressing portion 29 of the bottom lid 22 and pushes up the bottom lid 22. When the second lock cam 34 rotates in the direction of the arrow b to the state shown in FIG. 22A, the push-up operation by the push-up portion 34 is completed (step A8).

  Here, the first lock cam 33 does not contact the link 14 while rotating in the direction of the arrow b from the state of FIG. 22D to the state of FIG. 22A, so the slide lock 13 does not move. Thereby, the cover 11 remains locked in the closed state.

  FIG. 26 is an explanatory view showing the operation of the lock cam for unlocking the lid. FIG. 26A shows a state in which the first lock cam 33 and the second lock cam 34 are at the origin position.

  FIG. 26B shows a state in which the first lock cam 33 is rotated 9 degrees in the direction of arrow b from the origin position. When the first lock cam 33 rotates 9 degrees in the direction of the arrow b from the origin position, it contacts the cam contact surface 14b of the link 14.

  FIG. 26C shows a state in which the first lock cam 33 is rotated 75 degrees from the origin position in the direction of arrow b. When the first lock cam 33 is rotated 75 degrees in the arrow b direction from the origin position, the cam contact surface 14b of the link 14 is pushed, and the link 14 is rotated in the arrow d direction with the shaft portion 14a as a fulcrum.

  One end of the link 14 is rotatably connected to the other end of the slide lock 13 with the shaft portion 14a interposed therebetween. Thereby, the rotation operation of the link 14 is converted into the slide movement operation of the slide lock 13, and the locking claw 16 is retracted from the locking hole 11b of the lid body 11 shown in FIG.

  Thereby, the lock | rock of the cover body 11 is cancelled | released and it can remove from the insertion opening part 9 by rotating in a predetermined direction (step A9).

  While the second lock cam 34 is rotated 75 degrees from the origin position in the direction of arrow b, the flat portion of the push-up portion 34a is in contact with the bottom lid 22 and locks the bottom lid 22 in the closed state.

  When the system controller 92 rotates the first lock cam 33 and the second lock cam 34 by 75 degrees in the arrow b direction from the origin position, the system controller 92 stops driving the stepping motor 36a. And it is detected from the output of the upper cover detection sensor 19 whether the cover body 11 was removed (step A10).

  If the lid 11 remains attached, the stepping motor 36a is kept stopped, and the unlocked state of the lid 11 is maintained.

  When the lid 11 is removed, the system controller 92 rotates the stepping motor 36a from the state shown in FIG. 26C to the arrow a, and returns it to the origin position shown in FIG. 26A (step A11).

  When the system controller 92 detects from the output of the cam position detection sensor 39 that the first lock cam 33 and the second lock cam 34 have returned to the origin position, the system controller 92 stops the rotation of the stepping motor 36a.

  As described above, in the state where the first lock cam 33 is at the origin position, the locking claw 16 of the slide lock 13 projects from the closing opening 9. Further, in the state where the second lock cam 34 is at the origin position, the push-up portion 34a is in contact with the bottom lid 22 and pushed up. Thereby, it will be in the state which can throw in garbage from the insertion opening part 9. FIG.

  In the state where the bottom cover 22 is locked in the closed state by the second lock cam 34, the lower end surface of the push-up convex portion 32 is outside the rotation locus of the wing portion 46 of the rotary blade 44, and the bottom of the closed state is closed. The lid 22 does not hinder the rotation of the rotary blade 44.

<Crushing and drying operation>
The garbage input from the garbage input device 3 to the garbage crushing and drying device 4 by the input operation described above is crushed and dried in the processing container 42.

  The crushing / drying operation in the processing container 42 requires the bottom lid 22 to be closed. Therefore, when the bottom lid 22 is closed by the above-described charging operation and it is detected that the bottom lid 22 is normally closed, the system controller 92 starts the crushing and drying operation.

  That is, the PTC heater 52 is turned on and the processing container 42 is heated. Further, the fan 69 is rotated, and air blowing is started from the slit 48 of the blade portion 46 of the rotary blade 44. Further, the rotation of the motor 67 is started, and the rotary blade 44 is rotated in the direction of arrow c.

  When the rotary blade 44 is rotated in the direction of the arrow c, the garbage in the processing container 42 is scraped up by the blade portion 46 while receiving air from the slit 48. When the blade portion 46 of the rotary blade 44 passes through the cutter 62 provided in the cover unit 58, the cutter 62 passes through the groove portion 47 of the blade portion 46, so that the raw garbage scraped up by the blade portion 46 is removed from the cutter 62. It is crushed by.

  Since a plurality of cutters 62 are provided along the axial direction of the rotary blade 44, the garbage can be crushed finely. Further, since the positions of the cutters 62 are also shifted with respect to the circumferential direction, for example, an event in which one object is simultaneously cut by a plurality of cutters 62 hardly occurs, and an excessive force is applied to the rotary blades 44. prevent.

  A wiper 50 is attached to the tip of the blade portion 46 of the rotary blade 44, and the wiper 50 comes into contact with the inner surface of the processing container 42 near the bottom of the processing container 42. This prevents garbage from adhering to the processing container 42.

  In this way, by rotating the rotating blade 44, the garbage is stirred in the processing container 42, and the moisture is evaporated by blowing air from the slit 48 and dried. Further, the evaporation of moisture is promoted by heating the processing vessel 42 with the PTC heater 52.

  Since the PTC heater 52 has a self-temperature control function, it can reduce power consumption without consuming more power than necessary.

  In order to make the air blown from the rotor blades 44 warm air, a heater is provided in the air flow path from the fan 69 and temperature management is required, which makes the structure complicated. By sticking to 42 and using, the raw garbage in the processing container 42 can be heated, and drying can be accelerated | stimulated, performing normal temperature ventilation from the rotary blade 44. FIG. Moreover, by drying, the activity of microorganisms can be weakened and the generation of odor can be suppressed.

  The air in the processing container 42 is exhausted from the exhaust port 74 to the drain pipe downstream from the drain trap through the filter unit 75 and the check valve unit 76. Since the exhaust port 74 is disposed in the upper part of the processing container 42, it prevents moisture from flowing in directly. In addition, by using the filter unit 75, dry dust powder that has been crushed and dried is prevented from being exhausted.

  As described above, by providing the filter unit 75 with the brush 79 that can be operated from the outside, the filter 78 can be cleaned without removing the filter unit 75, and clogging of the filter 78 can be prevented. Instead of providing the brush 79, the filter 78 may be detachable so that it can be cleaned.

  In addition, since the exhaust from the processing container 42 is performed downstream of the drain trap, water does not normally flow backward. However, if the drain pipe is clogged, water may flow backward. For this reason, a sensor for detecting the inflow of water is provided in the path from the check valve 76 to the drain pipe, and if the water flows back, the check valve 76 is closed and the water into the processing vessel 42 is closed. Prevent backflow.

<Cover unit opening and closing operation>
During the crushing and drying operation described above, the cover unit 58 closes the discharge port 53 of the processing container 42. The dry dust powder crushed and dried in the processing container 42 is discharged from the discharge port 53 by an operation described later. Therefore, the opening / closing operation of the cover unit 58 prior to the discharging operation will be described with reference to FIG.

  The cover unit 58 closes the discharge port 53 in a state where the guide boss 59 is positioned at the closing guide portion 55 a of the guide groove 55. At this time, by operating the operation lever 60, the plate 60 a is fitted into the locking hole 57 of the guide rib 54. As a result, the cover unit 58 is locked with the discharge port 53 closed. Further, when the plate 60 a of the operation lever 60 is fitted into the locking hole 57 of the guide rib 54, the system controller 92 can detect from the output of the discharge port opening / closing detection sensor 61 that the cover unit 58 is closed.

  When the operating lever 60 is operated to retract the plate 60 a from the locking hole 57, the cover unit 58 can be pulled forward along the guide groove 55. At this time, the guide boss 59 moves in the guide groove 55 from the closing guide portion 55a to the lifting guide portion 55b. Thereby, the cover unit 58 can be lifted up and down along the lifting guide portion 55b.

  When the cover unit 58 is raised until the guide boss 59 reaches the upper end of the elevating guide part 55b, the guide boss 59 is pushed from the elevating guide part 55b to the open guide part 55c by pushing the cover unit 58 along the guide groove 55. Moving. Accordingly, the cover unit 58 is held in a state where the front of the discharge port 53 is opened and is erected above the discharge port 53.

  Here, since the cutter 62 is provided on the back surface of the cover unit 58, even if the cover unit 58 is opened as shown in FIG. 27, the cutter 62 is located between the back surface of the cover unit 58 and the processing container 42. It is not possible.

  As shown in FIG. 1, since the processing container 42 is accommodated in the cover 41, it is impossible to put a hand from the upper side of the opened cover unit 58 to the back side, so that the cutter 62 cannot be touched. It has become.

  Further, as shown in FIG. 27, a slight gap is formed between the lower portion of the opened cover unit 58 and the discharge port 53. However, since the gap is narrow, the hand cannot be put in and the hand is touched by the cutter 62. I can't do that.

  When replacing the cutter 62, the cover unit 58 is replaced. First, the lock lever 56 is moved to open the attachment / detachment guide portion 55d. Then, the cover unit 58 is moved along the raising / lowering guide part 55b of the guide groove 55, the guide boss 59 is positioned on the attachment / detachment guide part 55d, and the cover unit 58 is pulled forward.

  Thereby, the guide boss 59 is removed from the guide groove 55, and the cover unit 58 can be removed from the processing container 42. In order to attach the cover unit 58 to the processing container 42, the reverse procedure of removal may be performed.

  That is, in a state where the lock lever 56 is moved to open the attachment / detachment guide portion 55d, the guide boss 59 of the cover unit 58 is fitted into the attachment / detachment guide portion 55d, and the cover unit 58 is pushed in. As a result, the guide boss 59 fits into the lifting guide portion 55 b of the guide groove 55. When the cover unit 58 is lowered until the guide boss 59 reaches the lower end of the elevating guide part 55b, the guide boss 59 is moved from the elevating guide part 55b to the closing guide part 55a by pushing the cover unit 58. As a result, the cover unit 58 is held with the discharge port 53 closed.

  Further, by moving the lock lever 56 and closing the attachment / detachment guide portion 56d, the cover unit 58 is prevented from being inadvertently detached from the processing container 42 when the cover unit 58 is opened and closed.

<Discharge operation>
FIG. 28 is a flowchart showing the flow of processing during discharge. When it is detected from the output of a sensor (not shown) that the front panel 41a of the cover 41 shown in FIG. 1 is opened (step B1), the system controller 92 detects the position of the rotor blade 44 from the output of the origin position detection sensor 51a. To do. That is, when the rotor blade 44 is rotating, when the origin position detection sensor 51a detects the rotor blade 44, the rotation of the motor 67 is stopped and the rotor blade 44 is stopped at the origin position (step B2). Further, the rotation of the fan 69 is stopped. In this example, when the rotation of the fan 69 is stopped, the check valve 72 is closed. Further, the PTC heater 52 is stopped (step B3).

  If the upper lid detection sensor 19 detects the lid 11 when the front panel 41a is opened, the above-described closing operation may be performed, and the discharging operation cannot be performed. To emit.

  As shown in FIG. 29A, the user rotates the bag mounting arm 63 around the shaft portion 63a and pulls it out to the front of the apparatus. And the edge of the opening part of the bag 101 is pinched | interposed between the spatula of the bag attachment arm 63, and the bag 101 is made into the open state (step B4).

  In order to prevent the cover unit 58 from being opened before attaching the bag 101, a mechanism that cannot open and close the cover unit 58 unless the bag attaching arm 63 is pulled out may be provided.

  When the user pulls out the bag attachment arm 63 and attaches the bag 101, the user operates the operation lever 60 of the cover unit 58 to remove the plate 60a from the locking hole 57 of the guide rib 54, and opens the cover unit 58 as described above. (Step B5).

  Here, the system controller 92 detects from the output of the discharge opening / closing detection sensor 61 that the operating lever 60 of the cover unit 58 has been operated and the plate 60 a has been removed from the locking hole 57 of the guide rib 54.

  As shown in FIG. 29B, the user returns the bag mounting arm 63 to which the bag 101 is mounted to the original position, covers the discharge port 53 with the opening of the bag 101, and performs a predetermined operation button on the operation unit (not shown). Is pressed (step B6).

  When a predetermined operation button on the operation unit is pressed, the system controller 92 executes a dust discharge mode (step B7). Here, the dust discharge mode is executed when both unlocking by the operation lever 60 and pressing of the operation button are detected.

  In the dust discharge mode, the system controller 92 drives the motor 67 to first rotate the rotary blade 44 at the origin position in the direction of arrow c as shown in FIG. The system controller 92 controls the rotation amount of the rotor blade 44 by controlling, for example, the drive time so that the rotation amount of the rotor blade 44 stops at a position where the tip of the blade portion 46 does not exceed the lower end of the discharge port 53. To do. This stop position is referred to as a dust discharge position.

  When the rotary blade 44 is rotated from the origin position to the dust discharge position, the crushed and dried dry dust powder collected at the bottom of the processing container 42 is scraped up by the blade portion 46 of the rotary blade 44 and is discharged from the discharge port 53. Discharged.

  As shown in FIG. 29 (b), since the bag 101 is attached to the discharge port 53 by the bag mounting arm 63, the dry dust powder discharged from the discharge port is collected in the bag 101. Here, while the rotary blade 44 rotates from the origin position to the dust discharge position, the wiper 50 moves while being in contact with the inner wall of the processing container 42, so that dry dust powder can be prevented from remaining as much as possible. The clearance between the inner wall of the processing container 42 and the tip of the wiper 50 may be such that the dry dust powder does not fall downward.

  In addition, by providing the discharge plate 64 below the discharge port 53, when the bag 101 covers the discharge port 53, the discharge plate 64 enters the bag 101, and dry dust powder enters the bag 101 during the discharge operation. Prevents scattering outside without entering.

  When the system controller 92 rotates the rotating blade 44 from the origin position to the dust discharge position, the system controller 92 reverses the motor 67 and rotates the rotating blade 44 by a predetermined amount in the direction of arrow d as shown in FIG. As shown in FIG. 32, the system controller 92 controls the rotation amount of the rotor blade 44 by controlling, for example, the drive time so that the rotation amount of the rotor blade 44 stops at a predetermined position beyond the origin position. This stop position is referred to as a return position.

  The system controller 92 performs a reciprocating operation from the dust discharge position to the return position a plurality of times, then stops the rotary blade 44 at the origin position, and informs the user that the dust discharge operation has ended with a buzzer or a lamp. Notification is made (step B8).

  In this way, by performing the reciprocating operation of the rotary blade 44 from the dust discharge position to the return position, the dry dust powder collected at the bottom of the processing container 42 can be collected and reliably discharged from the discharge port 53. The reciprocating motion of the rotary blade 44 is between about 90 degrees.

  As described above, by setting the dust discharge position of the rotor blade 44 to a position where the tip of the blade portion 46 does not exceed the lower end of the discharge port 53, safety during the return operation of the rotor blade 44 is ensured. In addition, at the dust discharge position, the direction of the slits of the rotor blades 44 should not be horizontal or higher.

  This is because in the dust discharge mode, the air blowing by the fan 69 is stopped, so the air blowing from the slit 48 is not performed. For this reason, when the angle of the slit 48 becomes horizontal or higher, the dry dust powder or the like is removed from the slit 48. There is a possibility of entering the inside of the rotor blade 44. Accordingly, in the dust discharge mode, the rotation amount of the rotary blade 44 is controlled so that the slit 48 does not become horizontal or higher.

  Here, in the reciprocating operation of the rotary blade from the dust discharge position to the return position, for example, the origin position detection sensor 51a does not move even after a predetermined time has elapsed since the rotary blade 44 started to rotate in the arrow d direction from the dust discharge position. When the passage of the rotary blade 44 is not detected, it is determined that the foreign blade or the like is clogged and the rotary blade 44 can no longer rotate.

  When notified by the buzzer, lamp, or the like that the dust discharge operation has been completed, the user pulls out the bag mounting arm 63 (step B9) and closes the discharge port 53 with the cover unit 58. Then, the operating lever 60 of the cover unit 58 is operated to fit the plate 60a into the locking hole 57 of the guide rib 54 (step B10).

  Here, when the operation lever 60 of the cover unit 58 is operated and the plate 60 a is fitted in the locking hole 57 of the guide rib 54, the system controller 92 detects the lock of the cover unit 58 from the output of the discharge opening / closing detection sensor 61.

  The user further removes the bag containing the dry dust from the bag mounting arm 63 and discards it. Then, the bag mounting arm 63 is returned to the base. Finally, the front panel 41a of the cover 41 is closed (step B11).

  When it is detected from the output of the panel opening / closing detection sensor 93 that the front panel 41a of the cover 41 has been closed, the system controller 92 has detected the lock of the cover unit 58 from the output of the outlet opening / closing detection sensor 61. It will be in the standby state of the throwing-in garbage operation. If it is detected that the front panel 41a of the cover 41 is closed, but the lock of the cover unit 58 is not detected, the system controller 92 issues an alarm with a buzzer or a lamp.

  Here, in the above discharge operation example, the procedure for operating the operation button after opening the cover unit 58 is described. However, the procedure for opening the cover unit 58 after operating the operation button may be used. In this case, after a predetermined time lag, taking into account the time from when the operation button is operated and unlocking is detected from the output of the outlet opening / closing detection sensor 61 to when the cover unit 58 is actually opened, The rotating operation of the rotary blade 44 in the dust discharge mode described above is executed.

  Although not shown, a tray that can be pulled out is provided in the space formed in the lower portion of the processing container 42, so that the dry dust powder spilled during the discharging operation can be prevented from falling into the cover 41.

  Now, when a foreign object such as a fork is accidentally introduced from the insertion opening 9 shown in FIG. 1, the opening area of the discharge port 53 is larger than the bottom cover 22, so that the foreign substance dropped in the processing container 42 can be used. It is possible to discharge from the discharge port 53 by the discharge operation described above.

<Detection of amount of dust in processing container>
As the amount of dust in the processing container 42 increases, the processing capacity decreases. For this reason, the amount of dust in the processing container is detected, and when the amount of dust is large, the above-described discharge operation is promoted.

  FIG. 33 shows the configuration and operation of dust amount detection. The full tank detection sensor 88 is provided at a predetermined height on the side of the processing container 42, and detects the magnet 89 a provided on the fin 89 when the fin 89 is pushed up by garbage or the like by the operation of the rotary blade 44.

  As shown in FIG. 33 (b), when the amount of dust is large, when the fan 44 is rotated in the direction of arrow c by the stirring / drying operation, the full tank detection sensor 88 is turned on until the garbage passes through the fins 89. Therefore, the ON time of the full tank detection sensor 88 becomes longer.

  Accordingly, when the ON time of the full tank detection sensor 88 exceeds a predetermined time, the system controller 92 determines that the amount of dust in the processing container 42 has exceeded a specified amount. As a specific example, when the total on-time of the full tank detection sensor 88 is detected for a fixed time of about 30 minutes, and the total on-time of the full tank detection sensor 88 is about 10 minutes, An alarm is issued with a buzzer or lamp to prompt the execution of the discharge operation. Further, the above-described charging operation is not performed. Further, an alarm may be issued in a state where additional garbage can be added.

<Air volume control by fan>
As described above, when the amount of dust in the processing container 42 becomes full, the discharge operation is urged. However, when the amount of dust scraped up by the rotor blades 44 increases as the amount of dust increases, the pressure loss of the fan 69 increases. Will increase. Moreover, pressure loss also increases due to contamination in the piping. Normally, when the pressure loss increases, the rotational speed of the fan 69 increases. For this reason, the rotational speed of the fan 69 is detected, and the rotational speed of the fan 69 is controlled with reference to the table shown in FIG.

  For example, after selecting the rotational speed for driving the fan 69 with the instructed air volume from the instructed air volume and the current applied voltage, the selected rotational speed is compared with the actual rotational speed, and the rotational speed is The applied voltage is controlled to be the same.

<Installation of garbage disposal equipment>
In the garbage disposal apparatus 1, the processing container 42 and its peripheral devices are attached to the inside of the cover 41 as described above to constitute the apparatus main body. Further, the lower unit 6 constituting the garbage input device 3 is attached to the processing container 42. And the cover 41 is a form which the insertion cylinder part 21 and the drive shaft 35 of the lower unit 6 expose from the upper surface.

  In order to install the garbage processing apparatus 1, as shown in FIG. 35, first, the apparatus main body including the lower unit 6 is attached at a predetermined position below the sink 2.

  Next, the upper unit 5 is fitted into the opening of the sink 2 from above. At this time, as shown in FIG. 2, the insertion opening 9 of the upper unit 5 and the connection portion 24 of the insertion cylinder portion 21 of the lower unit 6 are fitted. Here, in the connecting portion 24, the length of the insertion portion of the portion where the insertion tube portion 21 and the insertion opening 9 are fitted has a clearance, and a scale is displayed so that the minimum required overlap can be visually confirmed. . Thereby, it can be determined easily and reliably at the time of construction that the input opening 9 and the input cylinder part 21 that require waterproofing are securely connected.

  Further, the tip of the drive shaft 35 on the lower unit 6 side is fitted into the shaft support portion 15 of the upper unit 5. When the distal end of the drive shaft 35 is fitted into the shaft support portion 15 of the upper unit 5, the first lock cam 33 is in a positional relationship that allows contact with the cam contact surface 14 b of the link 14.

  As described above, the cam contact surface 14b of the link 14 has a width in the vertical direction. Similarly, the contact range between the tip of the drive shaft 35 and the shaft support 15 is also given a width in the vertical direction.

  For this reason, the difference in the vertical dimension due to the installed sink 2 is absorbed by the dimensions of the connecting portion 24, the cam contact surface 14b, and the shaft support portion 15, so that fine adjustment in the height direction of the apparatus main body is unnecessary. It is. The upper unit 5 is fixed to the sink 2 by a method in which a fixing ring (not shown) is screwed into the upper unit 5. Note that the mounting and fixing of the upper unit 5 can be appropriately selected in accordance with the sink by an existing technique.

  Thereby, the leveling operation | work accompanying the height adjustment of an apparatus main body, etc. become unnecessary, and shortening of construction time, the assembly defect at the time of construction, etc. reduce. Further, since the cover 41 is not provided with a height adjusting mechanism, a gap between the lower portion of the cover 41 and the installation surface can be reduced, and accumulation of dust and the like due to long-term use can be prevented.

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