As a result, the lid 11 can be inserted into and removed from the insertion opening 9.

<Lid lock structure>
FIG. 5 is a top view showing a configuration example of the upper unit 5 as seen from the charging opening 9. The opening unit 9 of the upper unit 5 shown in FIG. 5 is opened in a circular shape and includes a lid body attaching / detaching unit 10. The lid body attaching / detaching portion 10 is provided so that the lid body 11 shown in FIG. 4 can be attached and detached, and a rib 10 a is provided at a predetermined inner wall position of the input opening portion 9. The structure fits into the groove 11a. When the lid 11 is fitted in the insertion opening 9 in a predetermined direction and rotated by a predetermined amount, the locking groove 11a of the lid 11 is locked with the rib 10a of the lid attaching / detaching portion 10, and the lid 11 is pulled upward. There is no structure.

In this example, the upper unit 5 has a lid lock waterproof structure 90. The upper unit 5 has a drainage channel 94. The drainage channel 94 is provided around the charging opening 9 of the upper unit 5 and has a predetermined slope 8b (see FIG. 8). An upper lid lock mechanism 12 is provided at the most upstream position of the drainage channel 94 to lock the lid body 11.

  FIG. 6 is a perspective view showing an assembly example of the lid lock waterproof structure 90 in the upper unit 5. According to the lid lock waterproof structure 90 shown in FIG. 6, the locking claw 16 of the upper lid locking mechanism 12 is provided at the most upstream position of the drainage channel 94, and a waterproof wall 94 a having a predetermined shape is provided around the locking claw 16. It is done. The convex engaging portion 16 a of the locking claw 16 locks the lid body 11 via a notch 94 c in which a part of the insertion opening 9 of the upper unit 5 is cut out at the most upstream position of the drainage channel 94. It is engaged with the groove 11b. The notch 94 c has a waterproof wall 94 b that spreads out into the drainage channel 94 at the most upstream position of the drainage channel 94. The gap between the waterproof wall 94b and the side surface of the locking claw 16 is rubbed. This is to prevent water from entering.

  FIG. 7 is a top view showing an example of attachment of the eye plate 95 in the upper unit 5. The eye plate 95 shown in FIG. 7 is attached so as to be annularly covered along the drainage channel 94 including the upper lid locking mechanism 12. The eye plate 95 has, for example, a hole 95a for allowing water to pass through the drainage channel 94 and a non-hole 95b that does not allow water to pass, and the non-hole 95b defines an upper region of the upper lid lock mechanism 12. The cover position is set.

  The eye plate 95 has a shape in which a hole corresponding to a portion directly above the upper lid lock mechanism 12 is closed. The eye plate 95 is formed by, for example, cutting out a stainless steel plate having a thickness of about 0.5 mm to 1.5 mm in an annular shape and opening predetermined portions at a predetermined arrangement pitch using a drill or the like. The hole portion 95 a opens a portion corresponding to a region covering the ring shape along the drainage channel 94. The hole 95a may be formed by punching such as press working. The portion that is directly above the upper lid lock mechanism 12 is shaped so as to be closed without opening a hole. Thereby, the eye plate 95 as shown in FIG. 7 is formed.

  As described above, according to the lid lock waterproof structure 90, by attaching the eye plate 95 having the hole portion 95a and the non-hole portion 95b in the predetermined region to the upper unit 5, the sink from the sink is connected to the upper lid lock mechanism 12. The intrusion of the drainage can be prevented by the non-hole portion 95b of the eye plate 95, so that the upper lid lock mechanism 12 can be prevented from being soiled and drained.

Thereby, the garbage processing apparatus 1 equipped with the lid lock waterproof structure 90 can be provided. In addition, the non-hole portion 95b of the eye plate 95 does not disturb the drainage in the hole portion 95a. Even when the garbage 7 is being thrown in, water intrusion from the periphery of the eye plate 95 toward the throwing opening 9 can be suppressed.

  In this example, the case where the waterproof wall 94b is provided has been described. However, the present invention is not limited to this, and the upper lid lock mechanism 12 may be installed without providing the waterproof wall 94b at the most upstream position of the drainage channel 94.

<Upper lid lock mechanism>
FIG. 8 is a front view including a partial cross section showing a configuration example of the upper lid lock mechanism 12. An upper lid locking mechanism 12 is attached to the upper unit 5 shown in FIG. The upper lid lock mechanism 12 includes a solenoid 13a and a rack member 13b that constitute an example of a cam limiting member. The solenoid 13a is attached to a shelf-like portion provided in the upper unit 5, for example.

  The solenoid 13a and the rack member 13b function to limit the rotation direction of the lock cam 33 to which the locking claw 16 is attached. The solenoid 13 a has a movable piece 14, and a rack member 13 b constituting an example of an action portion is attached to the tip of the movable piece 14. The rack member 13b is slidably provided on a cam contact surface that is an outer peripheral surface of the lock cam 33, and is provided so as to be engageable with the notch 33a (see FIG. 11). A compression spring 15 is attached between the solenoid 13a and the rack member 13b, and the rack member 13b is always pressed against the cam contact surface.

  In this example, when the lid body 11 is inserted into the insertion opening 9 of the upper unit 5 and rotated in a predetermined direction by a predetermined angle, the engaging portion 16a of the locking claw 16 shown in FIG. The rack member 13b is engaged with the stop groove 11b and restricts the reverse rotation of the lock cam 33 at a predetermined position (lid lock).

  Further, when the solenoid 13a operates momentarily and overcomes the urging force of the compression spring 15 to pull the rack member 13b, the reverse rotation restriction of the lock cam 33 is released. By releasing the lock, the lid body 11 can be rotated in the reverse direction.

  In this example, the drive shaft 35 of the lock cam 33 is provided with a double torsion coil spring 17 as an example of an urging member. When the reverse rotation restriction to the lock cam 33 is released by the solenoid 13a, the lock cam 33 is notched. At the same time as the rack member 13b comes out of the portion 33a, the lock cam 33 is urged in the reverse rotation direction. Due to the biasing force in the reverse rotation direction, the drive shaft 35 rotates in the same direction, so that the lid body 11 can easily escape from the lock region.

<Cover body detection function>
FIG. 9 and FIG. 10 are top views including a partial cross section showing operation examples (Nos. 1 and 2) of the upper lid detection sensors 19a and 19b. 11 and 12 are transition diagrams of the locking claw 16 showing an operation example of the upper lid lock mechanism 12.

  The upper unit 5 shown in FIG. 9A includes upper lid detection sensors 19a and 19b for detecting the magnets 18a and 18b of the lid body 11. The upper lid detection sensors 19a and 19b are magnetic sensors having Hall elements that detect magnetism and change output. The upper lid detection sensors 19a and 19b are configured to detect the magnets 18a and 18b attached to the side surface concave grooves of the lid body 11.

  The upper lid detection sensor 19a is a position that can be detected first when the lid body 11 is inserted into the insertion opening 9 of the upper unit 5. For example, when the drain port 8 is viewed on the left side, the drain port 8 is As a reference, it is disposed at a first position advanced 90 ° clockwise. Moreover, the upper lid detection sensor 19a is a position where the lid 11 is fitted in the insertion opening 9 and rotated in a predetermined direction, and the rib 11c of the locking groove 11b of the lid 11 is in contact with the locking claw 16. The magnet 18a is provided at a position where it can be detected. The upper lid detection sensor 19b is attached to a second position that is separated from the first position by a predetermined rotation angle, for example, 90 °. In this example, the second position is a position facing the drain port 8.

  A rib 11c, which is an example of a protrusion, is provided in the locking groove 11b of the lid 11 shown in FIG. 11A. The locking claw 16 has a convex engaging portion 16a, and the lock cam 33 has a notch 33a. Assuming this, when the lid is closed, when the lid 11 shown in FIG. 9A is inserted into the closing opening 9 and mounted without rotating (0 ° state = reference position), the upper lid detection sensor 19a is turned on. The upper lid detection sensor 19b remains off. At this time, the rack member 13 b shown in FIG. 11A is in a state of being positioned on the cam contact surface of the lock cam 33. Moreover, the latching claw 16 is in a state located in front of the rib 11c. In this example, the lid 11 is rotated, the rib 11c of the lid 11 is brought into contact with the convex engaging portion 16a of the locking claw 16, and the locking claw 16 is rotated counterclockwise.

  For example, when the lid 11 is rotated by 20 °, the rib 11 c rotates the lock cam 33. By this cam rotation, the rack member 13b shown in FIG. 11A gets over the notch 33a as shown in FIG. 11B. In other words, the rack member 13b enters the notch 33a. Further, when the lid 11 continues to rotate and is rotated by 45 °, as shown in FIG. 11B, the cover 11 enters the lock region beyond the notch 33a of the lock cam 33. At this time, the upper lid detection sensor 19a shown in FIG. 9B is still OFF, and the upper lid detection sensor 19b is still OFF.

  Further, when the lid body 11 is rotated clockwise to a position rotated 90 ° from the reference position, the upper lid detection sensor 19a shown in FIG. 10 is turned on and the upper lid detection sensor 19b is also turned on. The ON operation of the two upper lid detection sensors 19a and 19b is identified by a system controller 92 (not shown). For example, the system controller 92 detects sequential “10”, “00”, “11” of the upper lid detection sensors 19 a and 19 b to determine whether or not the lid body 11 is closed by the closing opening 9. Become. Accordingly, in the upper lid lock mechanism 12, the notch 33a shown in FIG. 11C serves as a stopper, and the rotation of the lid body 11 in the reverse direction (counterclockwise direction) is restricted.

  Further, when the solenoid 13a shown in FIG. 12A is energized for a moment when the lid is opened, the energization releases the rack member 13b from the notch 33a of the lock cam 33, thereby releasing the reverse rotation restriction to the lock cam 33. At this time, the solenoid 13a overcomes the biasing force of the compression spring 15 and pulls the rack member 13b, and at the same time, the double torsion coil spring 17 causes the lock cam 33 in a state in which the rack member 13b is pulled out from the notch 33a in the reverse rotation direction. It is made to energize. In this example shown in FIG. 12A, the lock cam 33 (lid 11) is rotated about 10 ° clockwise in the illustrated state by the rotational biasing force of the double torsion coil spring 17.

  Due to the biasing force in the reverse rotation direction, the drive shaft 35 rotates in the same direction, so that the lid body 11 can easily escape from the lock region. Thereby, the cover body 11 shown in FIG. 12B can be rotated in the reverse direction. At this time, the rack member 13b slides on the cam contact surface that has come out of the lock region by the biasing force of the compression spring 15. In this example, the lid body 11 can be taken out from the closing opening 9 from the vicinity of the position rotated about −40 ° from the lock position (rotated about 40 ° clockwise in the illustrated state). Thus, the lid lock can be released simply by driving the solenoid 13a and pulling the rack member 13b.

  Thus, according to the garbage processing apparatus 1 provided with the upper lid locking mechanism 12, when the lid body 11 is inserted into the insertion opening 9 of the upper unit 5 and rotated by a predetermined angle in the predetermined direction, the locking claw 16 The rack member 13b that is engaged with the locking groove 11b of the lid 11 and attached to the tip of the solenoid 13a that is not energized at a predetermined position limits the reverse rotation of the lock cam 33.

  Accordingly, the rotation of the lid body 11 in the reverse direction can be restricted, and the lid body 11 can be locked to the upper unit 5. In addition, as compared with the conventional lid locking mechanism, the upper lid locking mechanism 12 can be simply configured because it can be separated and independent from the bottom lid locking mechanism. Thereby, the garbage processing apparatus 1 which uses the upper cover lock mechanism 12 as a cover switch mechanism can be provided.

  In addition, since the user is limited by the solenoid 13a via the operation of rotating the lid 11 and the cam mechanism, the space can be reduced by simply pulling the small solenoid 13a for unlocking. Running costs can be achieved. Furthermore, the die cutting structure of the upper unit 5 is simplified, and the cost of the garbage disposal apparatus 1 can be reduced.

  Since the lid locking mechanism 12 is provided in the upper half of the upper unit 5, the dust throwing cylinder portion can be divided into two upper and lower parts compared to the conventional method. Further, since the upper lid lock mechanism 12 is housed in a size in which the sink nut (a sink engaging screw) can be submerged, a simple lock structure in which the current sink nut can be removed and the garbage disposal apparatus 1 can be retrofitted. It is configured.

  FIG. 13 is a cross-sectional view illustrating a configuration example of the bottom lid opening / closing mechanism 23 in the lower unit 6. The lower unit 6 shown in FIG. 13 includes a lid sealing structure 20, a charging cylinder portion 21, a bottom lid 22, and a bottom lid opening / closing mechanism 23. The upper and lower ends of the feeding cylinder portion 21 are opened, and a connecting member 24 is provided at the upper end portion. The connecting member 24 is connected to the charging cylinder 21 and the charging opening 9 of the upper unit 5. As the connecting member 24, a rubber annular joint and a hose band are used. Here, in the connecting member 24, the length of the insertion portion where the insertion tube portion 21 and the insertion opening 9 are fitted has 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 portion 21. A filter 26 is attached to the entrance of the drain port 25. The filter 26 covers the entrance of the drain port 25, for example, has a semi-cylindrical shape, has a function of capturing garbage and passing moisture, and is detachable so that replacement and cleaning can be performed.

  The bottom cover 22 is attached to the lower end of the charging cylinder part 21. For example, the bottom cover 22 is rotatably attached to the lower unit 6. 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 part 28 of the bottom cover 22 is formed outside the outer periphery of the cover part 27, and the bottom cover 22 opens and closes the opening at the lower end of the input cylinder part 21 by the cover part 27 by rotating about the shaft part 28. To do. 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, in a state where the bottom cover 22 is closed, the lowermost end of the inclined surface 27 d is substantially equal to the lower end of the drainage port 25 or slightly higher than the lower end of the drainage port 25.

  The bottom lid 22 is pushed and closed by a protrusion 44a of the stirring blade 44 by a rotational motion of the stirring blade 44 described later. For this reason, a push-up convex portion 32 is provided on the lower surface of the bottom lid 22. The push-up convex portion 32 has a shape along the locus of the tip of the stirring blade 44 and a slightly larger curved surface than the locus of the stirring blade 44 in a state where the closing cylinder portion 21 is closed by the bottom lid 22.

  The lid opening / closing mechanism 23 opens and closes the bottom lid 22 having a pressing portion (engaged portion) 29 at a predetermined position, and a driving unit 36 at a predetermined position on the lower unit outside the input cylinder portion 21. have. The drive part 36 is provided in the bracket 37 of the lower unit 6, for example. The drive unit 36 includes a motor 36a and a gear 36b. A stepping motor is used as the motor 36a. The motor 36a constitutes an example of a drive unit and supplies a rotational force to the gear 36b. The gear 36b has a drive shaft 35 '. The drive shaft 35 ′ is supported by, for example, a bracket 37, and a driving force is transmitted from the motor 36 a via the gear 36 b and the like. A reduction gear is used as the gear 36b, and the rotational speed of the motor is reduced to obtain a torque for driving the cam lock.

  A lock cam 34, which is an example of a second cam member, is attached to one end of the drive shaft 35 ', and the bottom cover 22 is engaged with a pressing portion 29, which is an example of an engaged portion. The lock cam 34 has a pushing surface 34a that constitutes an example of a fan-shaped (shell-shaped) engaging portion (see FIG. 17). A shaft portion 28 is formed so as to protrude from a part of the outer periphery of the lid portion 27. The pressing portion 29 is formed at a position facing the shaft portion 28 and is pressed by the lock cam 34. The pressing portion 29 of the bottom cover 22 and / or the pressing surface 34a of the lock cam 34 is provided with a gradient in a predetermined direction. The gradient is set so that the gradient increases as the cam body rotates.

  Further, in order to detect the direction of the lock cam 34, a magnet 38 is attached to the drive shaft 35 '. In addition, a cam position detection sensor 39 that constitutes an example of a position detection unit is attached to the bracket 37 so as to detect the magnet 38. Since the lock cam 34 is attached to the drive shaft 35 ′, the lock cam 34 rotates upon receiving the driving force of the drive unit 36. Thereby, the lock and unlock of the bottom lid 22 can be detected.

  In this example, the system controller 92 described in FIG. 49 is provided, and when the bottom cover 22 reaches the insertion cylinder portion 21 of the lower unit 6, the cam position detection sensor 39 detects the arrival of the bottom cover 22, and the cam The position detection signal S39 is output to the system controller 92.

  The system controller 92 controls the motor 36a based on the cam position detection signal S39. When the motor 36a rotates the lock cam 34, for example, the push surface 34a of the lock cam 34 picks up the pressing portion 29 of the bottom cover 22 due to the gradient of the push surface 34a of the lock cam 34, and the push surface 34a of the lock cam 34 The pressing portion 29 of the bottom cover 22 is pressed in the closing direction of the bottom cover 22. As shown in FIG. 14, a seal member 30 is attached to a predetermined position of the bottom cover 22 engaged with the above-described input cylinder part 21, and the bottom cover 22 is watertight with respect to the input cylinder part 21 of the lower unit 6. It is made to be able to hold.

  FIG. 14 is a perspective view illustrating a configuration example of the bottom cover 22 including the seal member 30. A bottom lid 22 shown in FIG. 14 includes a lid main body portion 22 ′ having a flat cylindrical convex portion at the center. A packing 30a constituting an example of the first sealing member is fitted into the convex portion of the lid main body 22 '. An annular silicone rubber having a U-shaped cross section is used for the packing 30a. An O-ring, a Y-type ring, or the like can be used for the packing 30a. The packing 30a only needs to have a shape that expands when pressure is applied from the inner side of the charging cylinder portion 21, and may be, for example, a hollow tube packing. This is because when the pressure is applied to the packing 30a, the pressing force against the seal surface 31 is increased as shown in FIG.

  The lid main body portion 22 ′ has a disc-shaped lid portion 27 that fits into the opening at the lower end of the insertion cylinder portion 21 shown in FIG. 13. The lid portion 27 has four leg portions 27e to 27h (all not shown). For example, four holes 22a to 22d are formed at predetermined positions of the lid main body 22 '. The leg portion of the lid portion 27 is fitted into this hole portion by engaging a packing cover 30b as an example of a second sealing member.

  The packing cover 30b is a flat rubber part and is attached above the packing 30a. The outer periphery of the packing cover 30b has an arc shape, and the crushing load is generally smaller than that of the packing 30a. The packing cover 30b is provided so as to be elastically deformed by abutting an inner wall rib 21a of the charging cylinder portion 21 described later by closing the bottom lid 22. Thereby, when the bottom cover 22 is opened, the garbage 7 is prevented from adhering to the packing 30a, and when the bottom cover 22 is closed, the garbage 7 is prevented from adhering to the seal surface 31 and the packing 30a. The effect can be obtained. Thereby, a reliable and favorable sealing effect can be obtained.

  The packing cover 30b also has four holes at the same position as the lid body 22 '. The packing cover 30 b is disposed so as to cover the packing 30 a attached to the convex portion of the bottom lid 22. In this example, the outer peripheral end portion of the packing cover 30b has a guide shape. The reason why the outer peripheral end portion has a guide shape is that when the bottom lid is opened, the bottom lid 22 that hangs down guides moisture from the upper portion downward along the outer peripheral end portion.

  FIG. 15 is an enlarged view showing an example of a sealing structure in the charging cylinder portion 21 and the bottom lid 22. The lid sealing structure 20 shown in FIG. 15 is a structure that seals between the charging cylinder portion 21 and the bottom lid 22 of the lower unit 6, and includes a plurality of attachments between the charging cylinder portion 21 and the bottom lid 22. A sealing member (sealing member 30) is provided, and one sealing member has a multiple sealing structure that assists the sealing function of the other sealing member.

  The input cylinder portion 21 of the lower unit 6 shown in FIG. 15 has an inner wall rib 21a that constitutes an example of an inner peripheral frame portion, and the inner wall rib 21a is arranged so as to protrude in the lid opening direction. Outside wall ribs 21a are provided outside wall ribs 21b that constitute an example of the outer peripheral frame portion. The outer wall rib 21b has a sealing surface (hereinafter referred to as a sealing surface 31) inclined outward with respect to the lid opening direction. In this example, the sealing surface 31 is disposed outside the inner wall rib 21a of the charging cylinder portion 21 in order to improve water tightness. For this reason, the inner wall rib 21 a extends downward to a height that covers the sealing surface 31.

  In this example, when the bottom cover 22 is closed by the input cylinder part 21, as shown in FIG. 15, the convex part of the bottom cover 22 is inserted in the position which penetrates into the inner wall rib 21a of the input cylinder part 21, and packing 30a. Are combined so as to straddle the inner wall rib 21a of the input cylinder part 21, and the outer peripheral surface of the packing 30a is brought into contact with the seal surface 31 of the outer wall rib 21b, and the packing cover 30b is connected to the inner wall rib 21a of the input cylinder part 21. Combined to hold down. As a result, the packing 30a can be pressed against the seal surface 31 to perform a reliable seal.

  Further, a recess 21c is provided outside the outer wall rib 21b, and a dust seal packing 30c constituting an example of a third sealing member is attached to the recess 21c of the outer wall rib 21b. The dust seal packing 30 c has a ring shape close to a cylinder, and is located outside the seal surface 31. For example, the dust seal packing 30c is attached so that the upper inner peripheral portion thereof is held by the concave portion 21c of the outer wall rib 21b, and when the bottom cover 22 is closed by the input cylinder portion 21, the bottom portion of the dust seal packing 30c is the bottom. Contact is made along the outer peripheral surface of the lid 22. As a result, when the bottom cover 22 is closed, the dust seal packing 30c comes into close contact with the outer peripheral surface of the bottom cover 22, and the packing 30a and the seal surface 31 can be protected from the entrainment caused by the flying of dry dust in the processing container. .

  16A and 16B are cross-sectional views showing an operation example of the bottom lid opening / closing mechanism 23. The bottom lid 22 shown in FIG. 16A opens and closes by rotating around the shaft portion 28 as a fulcrum. For this reason, the lid portion 27 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 charging cylinder portion 21. 16A, when the bottom lid 22 is closed, the seal member 30 protrudes from the lid portion 27 and the lid main body portion 22 ′ so that the seal member 30 can come into close contact with the seal surface 31a of the insertion cylinder portion 21. The amount is set.

  Now, as shown in FIG. 16A, when the bottom lid 22 is closed, the portions where the seal member 30 is exposed are the clearance portion between the lid portion 27 and the loading cylinder portion 21, and the lid body portion 22 ′ and the loading cylinder portion 21. The clearance part. For example, when the bottom cover 22 is closed, according to the seal structure that receives the packing 30a on the sealing surface 31, when the pressure from the inner side of the input cylinder portion 21 is applied, the packing 30a expands so as to expand. .

  Further, since the packing cover 30b is in contact with the inner wall rib 21a on the entire circumference, the solid garbage 7 is in contact with the packing cover 30b and the inner wall rib 21a even if juice or water flows to the packing 30a. Since it cannot pass through the part, it is possible to adopt a structure in which the garbage 7 does not adhere to the packing 30a and the seal surface 31.

  Even when a solid material such as a spoon or fork is erroneously charged, the seal member 30 is not directly damaged unless it is smaller than the clearance between the lid portion 27 and the charging cylinder portion 21. Moreover, since the contact area of the sealing member 30 and the injection | throwing-in cylinder part 21 can be taken widely, adhesiveness improves.

  Further, as shown in FIG. 16B, the bottom cover 22 opens and closes with the shaft portion 28 as a fulcrum, and the seal member 30 and the sealing surface 31 of the charging cylinder portion 21 open and close by abutment of the surfaces. In the figure, the packing cover 30b serves as an umbrella on the packing 30a to prevent the garbage 7 from adhering to the packing 30a when the bottom lid 22 begins to open and the garbage 7 falls into the processing container 42. To do. After the bottom cover 22 is detached from the insertion cylinder portion 21 as shown in FIG. 16B, the bottom cover 22 maintains a suspended posture until it becomes a substantially vertical state by its own weight. In this way, the bottom lid 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 packing cover member 30b when the bottom cover 22 is closed. Furthermore, O-rings having different diameters may be overlapped to form the sealing surface 31.

  Thus, according to the garbage processing apparatus 1 provided with the lid sealing structure 20, the inner wall rib 21 a is provided inside the packing 30 a, the packing cover 30 b, the dust seal packing 30 c, and the seal surface 31, and the input cylinder portion is provided at the bottom lid 22. When 21 is closed, the packing 30 a whose outer peripheral surface is in contact with the sealing surface 31 of the outer peripheral rib 21 b can be covered with the packing cover 30 b pressed by the inner peripheral rib 21 a of the input cylinder portion 21.

  Therefore, the sealing effect of the packing 30a can be improved compared to the conventional method. In addition, the packing cover 30b can prevent the garbage 7 from entering the packing 30a. As a result, the bottom lid 22 can be closed with good water tightness, and the highly reliable garbage disposal apparatus 1 including the lid sealing structure 20 can be provided.

  Further, since there is almost no distance that the packing 30a slides on the seal surface 31 and the packing 30a has a shape that is easy to bend, the torque for closing the bottom cover 22 is small, and the drive source of the lock cam 34 can be set small. It became so.

<Lock cam structure>
17A to 17D are diagrams illustrating a configuration example of a reciprocating rotation type lock cam 34. 17A is a perspective view of the lock cam 34, FIG. 17B is a front view thereof, FIG. 17C is a top view thereof, and FIG. 17D is a rear view thereof. In this example, a pressing surface 34 b that presses the engaged portion of the bottom cover 22 in the direction in which the bottom cover 22 opens is provided above the lock cam 34. As a result, even when the seal member 30 is stuck to the charging cylinder portion 21 after being unlocked due to the stickiness of the garbage 7 or the juice, the pressing surface 34b provided above the lock cam 34 opens the lid. Since the engaged portion of the bottom lid 22 is pressed in the direction, the bottom lid 22 can be detached from the charging cylinder portion 21 with good reproducibility and reliability.

  The lock cam 34 shown in FIG. 17A includes a pushing surface 34a and a pushing surface 34b with the drive shaft 35 'interposed therebetween. The pushing surface 34a is provided in the lower left part of the fan-shaped lock cam 34 shown in FIG. 17C. The pushing surface 34a of the lock cam 34 is composed of an upward slope and a flat surface continuous from the slope, and the lock cam 34 rotates in a predetermined direction so as to come into contact with the pushing portion 29 of the bottom lid 22 from below, and the bottom lid Push 22 up.

  In addition, the pressing surface 34b of the lock cam 34 is formed as a downward slope as shown in FIG. 17B, and the pressing surface 34b contacts the pressing portion 29 of the bottom lid 22 from above by rotating the lock cam 34 in the other direction. Touch the bottom lid 22 down. Here, by making the point of action of the force by the lock cam 34 on the bottom cover 22 opposite to the shaft portion 28, the bottom cover 22 can be reliably locked when locked in the closed state. FIG. 17D shows the posture of the lock cam 34 rotated by 180 °.

  18 and 19 are bottom views showing operation examples (Nos. 1 and 2) of the lock cam 34 related to the bottom cover 22. In this example, the lower unit 6 is provided with a bottom lid opening / closing mechanism 23 that constitutes an example of a fixing mechanism, and the bottom lid 22 is closed and fixed to the charging cylinder portion 21, or the bottom lid 22 is pulled from the charging cylinder portion 21. Removed and opened. For example, when the bottom lid 22 is opened, the lock is released by rotating the lock cam 34 in the reverse direction with respect to the lid closing time. Assuming that the bottom cover 22 does not open even when the lock is released, when the rotation is further advanced, the bottom cover pressing-down surface 34b arranged on the upper side of the lock cam 34 interferes with the bottom cover 22 and the bottom cover 22 22 is pushed down.

  FIG. 18 is a diagram illustrating an example of a state in which the lock cam 34 is at the origin position. In the lock cam 34 shown in FIG. 18, the flat portion of the push-up portion 34a is in contact with the bottom cover 22, and locks the bottom cover 22 in the closed state. In this locked state, the pushing surface 34a of the lock cam 34, which is composed of an upward slope and a plane continuous from the slope shown in FIG. 17B, rotates the lock cam 34 in a predetermined direction so that the bottom cover 22 is pressed. In this state, the bottom cover 22 is pushed up by contacting the portion 29 from below.

  When the bottom lid 22 is opened, the system controller 92 detects whether or not the lid body 11 is closed from the outputs of the upper lid detection sensors 19a and 19b, and confirms that the lid body 11 is closed. 34 is rotated to open the bottom cover 22.

  FIG. 19 is a diagram illustrating a state example in which the lock cam 34 illustrated in FIG. 18 is rotated 180 degrees in the direction of arrow b from the origin position. At this time, as shown in FIG. 17B, it is assumed that the bottom cover 22 does not separate from the charging cylinder portion 21 even if the lock cam 34 rotates from the origin position to around 180 °. This is a state in which the bottom cover 22 does not come off due to its own weight due to juice or dust. In response to this phenomenon, the pressing surface 34b of the lock cam 34 constituted by a downward slope comes into contact with the pressing portion 29 of the bottom cover 22 from the upper side by further rotating the lock cam 34 in the same direction. It is made to push down. After that, the bottom lid 22 hangs down due to natural fall. As a result, as shown in FIG. 16B, the bottom lid 22 can be opened from the input cylinder portion 21, and the garbage from the input opening 9 can be dropped into the processing container.

  When the bottom lid 22 is closed, the system controller 92 detects whether or not the lid 11 is closed from the outputs of the upper lid detection sensors 19a and 19b, and confirms that the lid 11 is closed. Then, the stirring blade 44 is rotated and the rib 44 a of the blade body 46 is pressed against the push-up convex portion 32 on the lower end surface of the bottom lid 22 to close the bottom lid 22. When the system controller 92 detects that the stirring blade 44 has reached directly above, the system controller 92 controls the drive unit 36 to rotate the motor 36a in the reverse direction. At this time, the lock cam 34 is rotated in the direction opposite to that at the time of opening.

  When the system controller 92 detects that the lock cam 34 has returned to the home position from the output of the cam position detection sensor 39 during the closing operation of the bottom cover 22, the system controller 92 stops the rotation of the motor 36a. As a result, the lock cam 34 stops rotating and closes and fixes the bottom lid 22.

  As described above, in a state where the lock cam 34 is at the origin position, the pushing surface 34 a is in contact with the bottom lid 22 and pushed up. When the bottom cover 22 is closed by the lock cam 34, the lower end surface of the push-up convex portion 32 is outside the rotation locus of the blade body 46 of the stirring blade 44, and the closed bottom cover 22 is in the stirring blade 44. There is no hindrance to the rotation.

<Other lock cam structures>
20A to 20D are diagrams showing a configuration example of a rotary circulation type lock cam 34 '. 20A is a perspective view of the lock cam 34 ′, FIG. 20B is a front view thereof, FIG. 20C is a top view thereof, and FIG. 20D is a rear view thereof.

  In this example, the lock cam 34 'is halved in fan shape compared to the lock cam 34 shown in FIG. 17A. For example, when the wide angle that forms the fan shape of the lock cam 34 is 90 °, the wide angle that forms the fan shape of the lock cam 34 ′ is about 45 °, which is a half thereof. The reason why the wide angle is halved in this way is that the lock cam 34 'is rotated in one direction without reciprocating rotation.

  Also in this example, a pressing surface 34b 'that presses the engaged portion of the bottom lid 22 in the direction in which the bottom lid 22 opens is provided above the lock cam 34'. Thus, even when the seal member 30 is stuck to the charging cylinder portion 21 after being unlocked due to the stickiness of the garbage 7 or the juice, the pressing surface 34b ′ provided above the lock cam 34 ′ is provided. Since the engaged portion of the bottom lid 22 is pressed in the lid opening direction, the bottom lid 22 can be detached from the charging cylinder portion 21 with good reproducibility and reliability.

  The lock cam 34 'shown in FIG. 20A includes a pushing surface 34a' and a pushing surface 34b 'with the drive shaft 35' interposed therebetween. The pushing surface 34a 'is provided at the lower left portion of the fan-shaped lock cam 34' shown in FIG. 20C. The pushing surface 34a 'of the lock cam 34' is composed of an upward slope and a flat surface continuous from the slope, and the lock cam 34 'rotates in a predetermined direction so as to come into contact with the pushing portion 29 of the bottom lid 22 from below. The bottom lid 22 is pushed up.

  Further, the pressing surface 34b 'of the lock cam 34' is formed as a downward slope as shown in FIG. 20B, and the pressing surface 34b 'is pressed by the pressing portion 29 of the bottom lid 22 as the locking cam 34' rotates in one direction. And the bottom lid 22 is pushed down. Here, by making the point of action of the force by the lock cam 34 ′ on the bottom cover 22 opposite to the shaft portion 28, the bottom cover 22 can be reliably locked when locked in the closed state. FIG. 20D shows the posture of the lock cam 34 ′ rotated by 180 °.

  FIGS. 21 to 23 are bottom views showing operation examples (parts 1 to 3) of other lock cams 34 ′ related to the bottom cover 22. Also in this example, the lower unit 6 is provided with the bottom lid opening / closing mechanism 23, and the bottom lid 22 is closed and fixed to the charging cylinder portion 21, or the bottom lid 22 is pulled off from the charging cylinder portion 21 and opened.

  FIG. 21 is a diagram showing an example of a state where the lock cam 34 'is at the origin position. In the lock cam 34 'shown in FIG. 21, the flat portion of the push-up portion 34a' shown in FIG. 20A comes into contact with the bottom lid 22 to lock the bottom lid 22 in the closed state. In this locked state, as shown in FIG. 20B, the push-up surface 34a ′ of the lock cam 34 ′ configured by an upward slope and a plane continuous from the slope rotates the lock cam 34 ′ in a predetermined direction. This is a state (origin position) in which the bottom cover 22 is pushed up by abutting against the pressing portion 29 of 22 from below.

  When the bottom lid 22 is opened, the system controller 92 detects whether or not the lid body 11 is closed from the outputs of the upper lid detection sensors 19a and 19b, and confirms that the lid body 11 is closed. The bottom lid 22 is opened by rotating 34 '.

  FIG. 22 is a bottom view showing a state example of the bottom lid 22 at the first open position. In the first opening position shown in FIG. 22, the lock cam 34 ′ is rotated 90 ° from the origin position, and the pressing portion 29 of the bottom cover 22 overlaps both the pressing surface 34a ′ and the pressing surface 34b ′ of the locking cam 34 ′. It is not in the state. This state is a position where the bottom cover 22 can be opened by its own weight. Even in this example, even if the lock cam 34 ′ shown in FIG. 20B rotates about 90 ° from the origin position, the bottom cover 22 may not be removed by its own weight due to juice or dust.

  FIG. 23 is a bottom view showing a state example of the bottom lid 22 at the second open position. In the second opening position shown in FIG. 23, the lock cam 34 ′ rotates 270 ° (180 ° from the first opening position) in the direction of the arrow b from the origin position, and the pressing portion 29 of the bottom cover 22 presses the locking cam 34 ′. In this state, neither the upper surface 34a 'nor the pressing surface 34b' overlaps.

  In this state, with respect to the above-described phenomenon, the pressing surface 34b ′ of the lock cam 34 ′ configured with a downward slope comes into contact with the pressing portion 29 of the bottom cover 22 from the upper side by the rotation of the lock cam 34 ′ in the same direction. After the bottom lid 22 is forcibly pushed down, it is a position just before the bottom lid 22 is opened by its own weight (or a position immediately after the opening is started). After that, the bottom lid 22 hangs down due to natural fall. As a result, as shown in FIG. 16B, the bottom cover 22 can be opened from the input cylinder portion 21, and the garbage from the input opening 9 is dropped into the processing container.

  When the bottom lid 22 is closed, the system controller 92 detects whether or not the lid 11 is closed from the outputs of the upper lid detection sensors 19a and 19b, and confirms that the lid 11 is closed. The stirring blade 44 is rotated, and the rib 44 a of the blade body 46 is pressed against the push-up convex portion 32 on the lower end surface of the bottom lid 22 to close the bottom lid 22. When the system controller 92 detects that the stirring blade 44 has reached directly above, the system controller 92 controls the drive unit 36 to rotate the motor 36a in the reverse direction. At this time, the lock cam 34 'rotates 90 ° in the same direction as when opened.

  When the system controller 92 detects that the lock cam 34 ′ has returned to the home position from the output of the cam position detection sensor 39 during the closing operation of the bottom cover 22, the system controller 92 stops the rotation of the motor 36 a. As a result, the lock cam 34 ′ stops rotating and closes and fixes the bottom cover 22.

  Thus, according to the garbage processing apparatus 1 provided with the lid opening / closing mechanism 23 of the rotating lid type, the pushing surface 34a of the lock cam 34 is provided with a gradient in a predetermined direction, and the bottom lid 22 is provided with the input cylinder portion 21. , When the motor 36a rotates the lock cam 34, the pushing surface 34a picks up the pressing portion 29 of the bottom lid 22 due to the gradient of the pushing surface 34a, and the pushing surface 34a moves in the bottom lid closing direction. The pressing portion 29 of the bottom lid 22 is pressed.

  Therefore, as compared with a method in which a driving force is applied to the rotating shaft of the bottom cover 22 and the bottom cover 22 is directly pressed against the charging cylinder portion 21 of the lower unit 6, the bottom cover 22 is attached with a lower torque and a higher tightening force. It can be locked to the charging cylinder part 21. As a result, the bottom cover 22 can be brought into close contact with the input cylinder portion 21 with good water tightness, and the sealing effect of the sealing member 30 pressed against the sealing surface 31 can be improved. In addition, since the parts constituting the lid opening / closing mechanism 23 are simple and the two functions of the bottom lid locking function and the lid forcibly opening function are performed by one part of the lock cam, the cost of the garbage disposal apparatus 1 can be reduced.

<Configuration of garbage crushing and drying equipment>
FIG. 24 is a perspective view illustrating a configuration example of the processing container 42 in the garbage processing apparatus 1. In this example, the stirring blade 44 reciprocates and rotates in the semi-cylindrical processing container 42 to stir and crush the garbage 7. In this example, five shafts 48a to 48e are protruded from the shaft portion 45, and a stirring blade body 46 is attached to the tips of these shafts 48a to 48e.

<Processing vessel structure>
The processing container 42 shown in FIG. 24 constitutes one of the main parts of the garbage crushing and drying apparatus 4 shown in FIG. 1, and the upper part is opened and the bottom part is semicylindrical. In this example, a discharge port 53 (see FIGS. 30, 31, and 42) is provided in front of the processing container 42 in the drawing, and the discharge unit 53 includes a cover unit 58 that constitutes an example of an opening / closing lid. Is movably attached. The discharge port 53 is provided at a position on the front surface of the processing container 42. The discharge port 53 is, for example, a rectangular opening. On both the left and right sides of the discharge port 53, guide ribs 54a and 54b are provided as shown in FIG. The guide rib 54 is an example of a side plate.

  Under each of the left and right guide ribs 54a and 54b, hook portions 57a and 57b are provided to engage the locking shafts 60a and 60a of the cover unit 58. In the drawing, the shaft 60 a (, 60 b) 56 and the hook portion 57 a (, 57 b) shown in the in-circle diagram constitute the lock mechanism 50 in the cover unit 58. The lock mechanism 50 will be described with reference to FIG.

  The lower unit 6 shown in FIG. 13 is attached to the upper part of the processing container 42. Further, the processing vessel 42 has a stirring / drying space 43 formed therein, and a stirring blade (stirring means) 44 is attached. At least the lower half of the stirring / drying space 43 has a cylindrical shape along the locus of the stirring blade 44.

  The processing container 42 includes an origin position detection sensor 51a for detecting the position of the stirring blade 44 and a bottom lid push-up position detection sensor 51b. In the example shown in FIG. 24, the stirring blade 44 is stopped at a position facing the discharge port 53 with the shaft portion 45 interposed therebetween. In this example, the origin position of the stirring blade 44 is a state in which the stirring blade body 46 is vertically downward. As will be described later, when the stirring 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 stirring blade 44 and The operation of closing the lid 22 is performed.

  A PTC heater 52 (heating means) is provided on the outer periphery near the bottom of the processing container 42 (see FIG. 3). For example, the PTC heater 52 is covered with a heat insulating material, is attached to the bottom, and heats the inside of the processing container 42. The temperature in the processing container 42 is about 45 ° C. when the garbage 7 is initially stirred, and is maintained at about 65 ° C. when the state changes to a dry powder.

  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, since the current consumption decreases as the temperature of the PTC heater 52 rises and then reaches a saturation region at a constant temperature, the current consumption is stabilized at a low value. There is an advantage that the temperature of the heating element can be prevented from rising abnormally.

  The processing container 42 described above is provided with a pair of bearing portions 42a and 42a, and a shaft portion 45 is rotatably attached to the bearing portions 42a and 42a. In this example, a stirring blade structure 40 including a shaft portion 45 is provided.

<Composition of stirring blade>
FIG. 25 is a perspective view showing an example of a stirring blade structure in the garbage processing apparatus 1. A stirring blade structure 40 shown in FIG. 25 includes a stirring blade 44 that stirs the garbage 7 and a shaft portion 45. The stirring blade 44 includes a stirring blade body 46 and shafts 48a to 48e that constitute an example of a rod-shaped body. The stirring blade body 46 has a plate shape, and has, for example, five hook-shaped portions 46a to 46e on one side. Five shafts 48a to 48e are attached to the other side of the stirring blade body 46 in correspondence with the individual bowl-shaped portions 46a to 46e. The shafts 48a to 48e are attached to a shaft portion 45 having a predetermined thickness.

  The stirring blade body 46 includes a stirring plate 47 and a reinforcing plate 49 (see FIG. 26). The stirring plate 47 constitutes an example of a stirring blade member, and a resin molded product provided with flanges 46a to 46e is used. The back surface of the stirring plate 47 is lined with a reinforcing plate 49. As the reinforcing plate 49, a metal plate having corrosion resistance, for example, a stainless steel (SUS) plate is used. The other side of the stirring plate 47 is a protrusion 47a. A rib 44a having a predetermined shape is provided on the protrusion 47a. When the bottom cover 22 is closed, the bottom cover 22 is pushed up by the rib 44a. .

  FIG. 26 is a perspective view showing an assembly example of the stirring blade 44. In the stirring blade 44 shown in FIG. 26, the stirring blade body 46 is attached to the five shafts 48 a to 48 e in a state where the stirring plate 47 provided with the flanges 46 a to 46 e is lined with the reinforcing plate 49. The stirring plate 47 lined with the reinforcing plate 49 is attached to the shafts 48a to 48e with 11 screws 86, for example. The five shafts 48 a to 48 e of the stirring blade body 46 are fitted and fixed in five holes 45 a provided in the shaft portion 45, respectively. Thereby, the stirring blade 44 having the stirring blade structure 40 can be assembled.

  FIG. 27 is a cross-sectional view showing an example of attachment of the stirring blade 44 in the processing container, and is a view in which the processing container 42 is cut along a plane along the axial direction of the shaft portion 45. According to the stirring blade structure 40 shown in FIG. 27, the shaft portion 45 of the stirring blade 44 is attached to the bearing portions 42 a and 42 b provided on both outer sides of the processing vessel 42. The stirring blade 44 has a predetermined opening width (gap) d1 between the bowl-shaped portion 46a and the bowl-shaped portion 46b of the stirring blade body 46. Similarly, the other flange portions 46b and 46c, the flange portions 46c and 46d, and the flange portions 46d and 46e have predetermined opening widths d2, d3, and d4, respectively. Four crushing blades 62 (see FIG. 29) are passed between the flanges 46a to 46e having the opening widths d1 to d4. Thereby, conveyance of the garbage 7 to the crushing blade 62 and conveyance of the garbage 7 to the discharge port 53 at the time of discharge | emission operation can be performed smoothly.

  Further, a predetermined arrangement width w1 is provided between the shaft 48a and the shaft 48b attached to the shaft portion 45. The other shafts 48b and 48c, shafts 48c and 48d, and shafts 48d and 48e have the same arrangement widths w2, w3, and w4. Air for drying is passed between the shafts 48a to 48e having the arrangement widths w1 to w4.

  The stirring plate 47 is attached only to the tips of the shafts 48a to 48e, and a structure in which only five shafts 48a to 48e are provided between the shaft portion 45 and the stirring plate is employed. With this structure, excess garbage 7 falls from the gap to the rear of the stirring blade 44. Thereby, stirring load can be reduced. As will be described later, the agitating blade 44 reciprocates on the lower side in the processing container 42 and then rotates so as to make one round in the processing container 42 at regular intervals. By this rotation, the garbage 7 that has fallen to the rear of the stirring blade 44 can be crushed and dried during the next reciprocating rotation.

  As in this example, by increasing the clearance between the stirring blades 44 and the space between the shafts 48a to 48e, a flow path for the drying air in the processing vessel 42 is secured, and a smooth air flow can be achieved. . Since the gap between the shafts 48a to 48e is larger than that in the conventional method, and the garbage 7 is easily dropped from the stirring blade 44, the garbage 7 that has dropped to the rear of the stirring blade 44 is substantially stirred. For example, what has fallen behind the stirring blade 44 can be collected again by one rotation operation of the stirring blade 44 performed at an operation speed of once / 30 seconds. The excess garbage 7 being stirred is appropriately dropped behind the stirring blade, so that the garbage 7 in the processing vessel 42 does not stay at a fixed position on the stirring blade 44.

  A gear unit 65 is engaged with one end of the shaft portion 45 to which the above-described stirring blade 44 is attached. A motor 67 that constitutes a drive unit is attached to the gear unit 65, and the drive force is transmitted to the shaft portion 45 of the stirring blade 44 via the gear unit 65. For example, the gear unit 65 has a flat gear, a small gear, and a counter gear (not shown). When the motor 67 is rotated, a driving force is transmitted to the stirring blade 44 via the small gear, the counter gear, and the flat gear. The stirring blades 44 are reciprocally rotated and rotated about the shaft portion 45 as a central axis. The motor 67 is an example of a driving unit.

  As the motor 67, a DC motor capable of normal rotation and reverse rotation is used. A system controller 92 is connected to the motor 67, and a motor control signal S 67 is output to the motor 67 to perform forward and reverse control of the stirring blade 44. For example, the system controller 92 controls the motor 67 so that the stirring blade 44 is reciprocally rotated in a predetermined region including the crushing blade 62 and the stirring blade 44 is rotated in the processing container 42 after a predetermined time has elapsed. .

  Thus, according to the garbage processing apparatus 1 provided with the stirring blade structure 40, five shafts are provided on the other side of the stirring blade body 46 having the five bowl-shaped portions 46a to 46e on one side. 48a to 48e are attached, and the shafts 48a to 48e are attached to predetermined shaft portions 45 corresponding to the individual hook-like portions 46a to 46e.

  Accordingly, when the garbage 7 is agitated, the air flows into the individual gaps of the five bowl-shaped portions 46a to 46e of the stirring blade body 46 and the individual spaces of the five shafts 48a to 48e of the shaft portion 45, respectively. Since the path can be formed, the air for drying can be circulated using each air path. As a result, the shaft portion 45 can be made thinner compared to the conventional rotor blade structure that blows out air from the rotor blade shaft, thereby reducing the space required for the stirring blade parts, reducing the size of the application device, and reducing its cost. Can be planned.

  FIG. 28 is a perspective view illustrating a configuration example of the cover unit 58. The cover unit 58 shown in FIG. 28 is detached from the discharge port 53 and separated from the processing container 42. The cover unit 58 includes a handle 60. The handle 60 has a T shape and includes shafts 60a and 60a on the left and right.

  FIG. 29 is a perspective view illustrating a configuration example of the crushing blade 62. The crushing blade 62 shown in FIG. 29 constitutes an example of crushing means, and is provided on the back side of the cover unit 58 serving as an example of a predetermined position inside the processing container 42. In this example, four crushing blades 62 are fixed to the back side of the cover unit 58. Each crushing blade 62 protrudes into the processing container 42 from the back surface of the cover unit 58 in a position where the discharge port 53 is closed, and the position of the stirring blade 44 in the rotational circumferential direction and the position of the shaft portion 45 of the stirring blade 44 in the axial direction. Are displaced from each other. Each crushing blade 62 is punched and cut from a metal plate of a predetermined size, formed into a fan shape, and a serrated blade portion 62a is formed on one side edge portion thereof.

  For example, the four crushing blades 62 are fixed in a staggered manner inside the cover unit 58. In this example, the uppermost crushing blade 62 provided in a staggered manner by the four crushing blades 62 is disposed at a position substantially equal to the height of the shaft portion 45 of the processing container 42 (see FIG. 3). This is because, in the reciprocating rotation operation, when the garbage 7 is scraped up extremely upward, most of the garbage 7 falls rearward from the stirring blade 44, and the garbage 7 does not reach the crushing blade 62. For this reason, the height of the garbage 7 is set so as not to fall excessively backward.

  30 to 37 are explanatory views showing the configuration of the cover unit 58. FIG. 30 is a perspective view showing a state in which the cover unit 58 is opened, and the discharge port 53 is indicated by a broken line. 31 and 32 are cross-sectional views showing a state where the cover unit 58 is opened. FIG. 31 shows a state in which the cover unit 58 is in a discharge position described later, and FIG. 32 shows a state in which the cover unit 58 is in an attachment / detachment position described later.

  FIG. 37 is an explanatory diagram of the lock mechanism 50 of the cover unit 58. FIG. 37A is a view in which the cover unit 58 closes the processing container 42. FIG. 37B is a diagram in which the operation lever unlocks the cover unit 58. FIG. 37C is a view in which the cover unit 58 is opened from the processing container 42.

  As shown in FIGS. 30 to 37, the cover unit 58 is formed in a shape that covers the discharge port 53, and is rotatably attached to the suspension base portion 42 g of the processing container 42 by the cover unit rotation shaft 55. As shown in FIG. 28 and the like, near the lower end of the cover unit 58, a handle 60 having a shaft 60a and formed in a T shape is provided. Both end portions of the shaft 60 a protrude from the both side surfaces of the cover unit 58 by a predetermined amount. Further, shaft grooves 42h formed in an arc shape are provided on both side surfaces of the cover unit 58, and the shaft 60a is movable in the shaft groove 42h.

  Furthermore, the shaft 60a is urged below the shaft groove 42h by a spring or the like (not shown). When no force is applied to the handle 60 and the shaft 60a, as shown in FIG. It will be in the state located in the lowest part. As shown by an arrow p in FIG. 37B, by pushing the handle 60 downward, the shaft 60a moves upward in the Schft groove 42h as shown by an arrow q.

  Further, a hook portion 57 formed in a bowl shape is provided at a location corresponding to the shaft 60a in the vicinity of the lower end portion of the discharge port 53 of the processing container 42. As shown in FIG. 37A, when the cover unit 58 is closed and the shaft 60a is fitted into the hook-shaped hook portion 57, the cover unit 58 is in a locked state with the discharge port 53 closed.

  Further, by providing the cover unit rotating shaft 55 with, for example, a rotary damper or a one-way hinge, the cover unit 58 is fixed at a predetermined rotational position. The rotary damper generates a biasing force in the rotational direction of the shaft by including a spring or the like that connects the inner ring and the outer ring. By providing a rotary damper so as to urge the cover unit 58 in the direction to open the discharge port 53 with respect to the cover unit rotation shaft 55, the cover unit 58 is fixed at a predetermined rotational position.

  The one-way hinge generates a torque in one direction and does not generate torque in the other direction and is in an idling state. By providing a one-way hinge so that torque is generated in the cover unit 58 in the direction of closing the discharge port 53 with respect to the cover unit rotation shaft 55, the cover unit 58 is similarly fixed at a predetermined rotational position.

  The shaft 60a includes a magnet. The hook portion 57 includes a discharge port opening / closing detection sensor 61. The discharge port opening / closing detection sensor 61 is a magnet sensor, and detects the magnet when the shaft 60a is in a locking position by the hook portion 57. Accordingly, it can be determined based on the open / close detection signal S61 that the shaft 60a is locked by the hook portion 57 and the cover unit 58 is in the locked state with the discharge port 53 closed. The discharge opening / closing detection sensor 61 is an example of an opening / closing detection means.

  FIG. 33 to FIG. 36 are explanatory views of attachment / detachment of the cover unit 58 to / from the processing container 42, and only a part of the members is shown for explanation. Further, in FIGS. 33 to 36, a part of the members are seen through and indicated by broken lines. FIG. 33 shows a state where the cover unit 58 is in the discharge position. FIG. 34 shows a state in which a stopper 42i described later is slid upward by a predetermined amount. FIG. 35 shows a state in which the cover unit 58 is slightly rotated from the discharge position in the direction of opening the discharge port 53. FIG. 36 shows a state where the cover unit 58 is removed from the processing container 42.

  As shown in FIGS. 3 and 30 to 36, a stopper 42 i is provided on the upper portion of the exhaust port 53 of the processing container 42. As shown in FIGS. 33 and 34, the stopper 42i is attached so as to be slidable by a predetermined amount in the vertical direction. The stopper 42i includes a rotation restricting pin contact portion 42ii with which a later-described rotation restricting pin 58a comes into contact.

  As shown in FIGS. 33 to 36, the cover unit 58 is rotatably supported on the cover unit rotation shaft 55 by a U-shaped portion 58b provided on the upper portion. Further, the cover unit 58 includes a rotation restricting pin 58a at the upper part.

  In a state where the stopper 42i is positioned at the lowermost position and the cover unit 58 is rotated so as to be positioned at the discharge position, as shown in E of FIG. 33, the rotation restricting pin 58a is brought into contact with the restricting pin contact portion 42ii of the stopper 42i. It comes into contact. At this time, as shown in F, the engaging portion 58c of the cover unit 58 and the engaging portion 42k of the processing container 42 are engaged. Here, the discharge position is, for example, a position rotated about 27 degrees from the position where the cover unit 58 closes the discharge port 53.

  As shown in FIGS. 34 and 35, when the stopper 42i is slid upward by a predetermined amount, the rotation restricting pin 58a and the stopper 42i are not in contact with each other, and the cover unit 58 is rotated from the discharge position to the opening direction of the discharge port 53. It becomes possible to make it. Here, when the cover unit 58 is rotated from the discharge position in the direction to open the discharge port 53, the engagement portion 58c of the cover unit 58 is engaged with the processing container 42 as shown in G of FIG. 34 and H of FIG. Since the joint portion 42k is overcome, vibration is generated in the cover unit 58 and a clicking sound is generated.

  As shown in FIG. 35, by rotating the engagement portion 58c of the cover unit 58 over the engagement portion 42k of the processing container 42, the cover unit 58 is pulled down as shown in FIG. 58 can be removed from the processing container 42.

  The removed cover unit 58 can be attached to the processing container 42 by performing a procedure reverse to the procedure described above. Here, the stopper 42i is slidable in the vertical direction. For this reason, when the cover unit 58 is attached to the cover unit rotating shaft 55 and when the attached cover unit 58 is rotated in the direction to close the discharge port 53, the stopper 42i slides upward, The rotation operation is not hindered by the stopper 42i. Accordingly, it is possible to perform the attachment of the cover unit 58 to the processing container 42 and the rotation in the closing direction of the discharge port 53 without operating the stopper 42i.

  The position where the engagement unit 58c of the cover unit 58 gets over the engagement unit 42k of the processing container 42 and the cover unit 58 is detachable from the processing container 42 is referred to as an attachment / detachment position of the cover unit 58.

<Front panel configuration>
FIG. 38 is an explanatory view showing a state in which the front panel 41a is opened. As shown by the arrows in FIG. 38, the front panel 41a is attached to the cover 41 so as to be freely opened and closed. The cover 41 includes a sensor 93 that detects opening and closing of the front panel 41a. For example, a button switch is used as the sensor 93.

<Intake mechanism>
As shown in FIGS. 2 and 38, the front panel 41 a includes an air inlet 73 for taking air into the cover 41. The intake port 73 includes a check valve 72 that functions as a check valve. For example, when the pressure in the cover 41 becomes negative due to intake air by driving the blower fan 69, the check valve 72 opens and is able to take in outside air from the intake port 73. Further, by stopping the driving of the blower fan 69, when the pressure difference between the inside of the cover 41 and the outside is zero or the pressure in the cover 41 becomes a positive pressure, it is closed by a spring or its own weight.

  As a result, the check valve 72 is opened at the intake port 73 by the intake air by driving the blower fan 69, and the outside air is taken in. Thereby, the blower fan 69 blows air into the processing container 42. When the driving of the blower 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 73.

<Blower mechanism>
FIG. 39 to FIG. 42 are configuration diagrams schematically showing an air blowing mechanism as a drying means and an exhaust mechanism as an exhaust means of the garbage processing apparatus 1. FIG. 39 is a schematic plan view of the garbage processing apparatus 1 and is shown by a broken line in a state where a part thereof is seen through for explanation. FIG. 40 is a schematic perspective view showing a state in which the garbage disposal apparatus 1 is viewed obliquely from the front, and FIG. 41 is a schematic perspective view showing a state in which the garbage disposal apparatus 1 is viewed from the oblique rear. FIG. 42 is a perspective view of the processing container 42 and shows an example including a filter dust removal unit of a first example to be described later.

  As shown in FIGS. 39 to 41, the garbage processing apparatus 1 includes a blower fan 69 on a side portion of the processing container 42. The blower fan 69 is a so-called sirocco fan. The blower fan intake port 69 a of the blower fan 69 is in a state of communicating with the intake port 73 described above inside the cover 41. Further, a blower fan exhaust port 69b is connected by a blower duct 70 to a process container intake port 42u provided on a side surface of a container upper case 42c attached to the upper part of the process container 42. Further, as shown in FIGS. 39 and 42, a rectifying plate 42j extending in the vertical direction is provided in the vicinity of the processing container intake port 42u of the processing container 42 in parallel with the processing container intake port 42u. The rectifying plate 42j is more preferably provided with an extending portion 42jj as shown in FIG. This is because it is possible to reliably guide the intake air. The blower fan 69 is an example of a drying unit and an example of a blower unit. The rectifying plate 42j and the extending portion 42jj may have a shape that spreads toward the bottom as shown in FIG. 42 (b).

  Further, the processing container intake port 42u may be provided on the upper surface of the container upper case 42c, and the blower fan exhaust port 69b may be connected to the processing container intake port 42u provided on the upper surface of the container upper case 42c by the air duct 70. When the processing container intake port 42u is provided on the upper surface of the container upper case 42c, the rectifying plate 42j and the extending portion 42jj may not be provided. This is because, as will be described later, as compared with the case where the processing container intake port 42u is provided on the side surface of the container upper case 42c, it is possible to reliably blow air toward the lower side of the processing container 42. The processing container inlet 42u is an example of a blower opening provided in the processing container.

  By providing the processing container air inlet 42u on the side surface or upper surface of the container upper case 42c attached to the upper part of the processing container 42, the processing container air inlet 42u is clogged with garbage or the like thrown into the processing container 42u. Can be prevented.

<Exhaust mechanism>
FIG. 43 is an explanatory diagram showing a configuration of an exhaust mechanism that is an example of exhaust means from the processing container 42. 43A is a perspective view showing an outline of the exhaust mechanism, and FIG. 43B is a cross-sectional view showing an outline of the exhaust mechanism. FIG. 43 shows an example provided with a filter dust removal unit 71 of a first example described later. FIG. 44 is a cross-sectional view showing the filter dust removal unit 71 of the first example. 45 is a perspective view showing the filter dust removal unit 80 of the second example, and FIG. 46 is a cross-sectional view showing the filter dust removal unit 80 of the second example.

  As shown in FIGS. 3, 42, and 43, the processing container 42 has an exhaust port 74 formed in the upper part. The exhaust port 74 is an example of an exhaust port provided in the processing container. As shown in FIG. 43, at the upper part of the exhaust port 74, a filter unit 75 which is an example of dust collecting means, a filter dust removing unit 71 of the first example which is an example of dust removing means (or a filter of the second example). A dust removal unit 80) and an exhaust fan 97 as suction means are provided. The filter unit 75 has a filter 78 provided at a position covering the exhaust port 74. First, the case where the garbage processing apparatus 1 includes the filter dust removal unit 75 of the first example will be described with reference to FIGS. 42, 43, and 44.

  The filter dust removing unit 71 of the first example is a comb-like plate having an L-shaped cross section that is rotatably attached to a shaft 79a as shown by an arrow g in FIG. 43B as an example of a vibration imparting mechanism. 79 and a cam 77 that is driven by a motor 79 b and presses the plate 79. The plate 79 is an example of an impact piece.

  As shown in FIG. 44A, the plate 79 is urged in a direction in which the filter contact portion 79c comes into contact with the filter 78 by a spring 71a. As shown by the arrow I in FIGS. 44 (b) and 44 (c), when the cam 77 is rotated by the motor 79b, the plate 79 is reciprocally rotated by the shaft 79a as shown by the arrow J, and the filter contacts An impact is applied to the filter 78 by the portion 79c, and the dust attached to the filter 78 can be removed. The spring 71a is an example of a biasing unit.

  Next, the case where the garbage processing apparatus 1 includes the filter dust removal unit 80 of the second example will be described. As shown in FIGS. 45 and 46, the filter dust removal unit 80 of the second example includes a brush 80b that is rotatably attached by a shaft 80a as an example of a vibration applying mechanism. The brush 80b is formed in a spiral shape around the shaft 80a. As shown in FIG. 46, the tip of the brush 80b is in contact with the filter 78.

  As shown by the arrow in FIG. 46, the shaft 80a is rotated by the motor 80c, so that an impact is applied to the filter 78 by the brush 80b, and dust attached to the filter 78 can be removed.

  Returning to FIG. 43, even if any one of the filter dust removal unit 71 of the first example or the filter dust removal unit 80 of the second example is provided, a suction means is provided on the upper portion of the filter dust removal unit. Exhaust fan 97 is provided. Further, the filter unit 75 can be removed and replaced, and the performance of the entire apparatus can be maintained.

  The exhaust port 74 is connected to the exhaust duct A85 via the filter 78, the filter dust removing unit 71 (or the filter dust removing unit 80), and the exhaust fan 97. The exhaust duct A85 is provided with a check valve 76 that is rotatably attached as indicated by an arrow r as a check valve. The check valve 76 opens, for example, by exhausting air by driving the blower fan 69 or the exhaust fan 97. As a result, as shown by the arrow in FIG. 43 (a) and the arrow f in FIG. 43 (b), the exhaust duct 74 can be exhausted from the exhaust port 74. Further, the check valve 76 is configured to close by its own weight by stopping the driving of the blower fan 69 and the exhaust fan 97.

  As shown in FIG. 43, the filter 78 is located upstream of the exhaust fan 97 in the exhaust path. Thereby, the granular powder scattered from inside the processing container 42 is collected by the filter 78, and the granular powder can be prevented from adhering to the exhaust fan 97.

  As shown in FIGS. 39 to 41, the exhaust duct A85 is connected to the drain pipe 87 via an elbow duct 85a and an exhaust duct B86. By providing such a configuration, the check valve 76 is opened by driving the blower fan 69 or the exhaust fan 97, and the air in the processing container 42 is discharged from the drain pipe 87 via the exhaust duct A85 and the exhaust duct B86. Exhausted inside. Further, by stopping the driving of the blower fan 69 and the exhaust fan 97, the check valve 76 is closed and the air in the drain pipe 87 is prevented from entering the processing container 42.

  In the examples shown in FIGS. 3, 42, and 43, the exhaust port 74 is provided on the upper surface of the processing container 42. However, the side surface of the processing container 42 is positioned higher than a predetermined position (for example, the exhaust port 53 The exhaust port 74 may be provided at a higher position. By providing the discharge port 74 on the upper surface of the processing container 42 or at a position higher than a predetermined position, it becomes possible to prevent the discharge port 74 from being clogged with garbage or the like introduced into the processing container 42.

<Structure of dry waste powder storage means installation mechanism / dry waste powder storage means>
As shown in FIGS. 3 and 40, the processing container 42 includes a dust storage tray installation unit 111 and bag adapter installation units 110 a and 110 b below the discharge port 53. The garbage storage tray installation unit 111 is formed in a planar shape. The bag adapter installation portions 110a and 110b are formed in a stepped shape having a predetermined height on the left and right sides of the discharge port 53 with the garbage storage tray installation portion 111 interposed therebetween.

  As shown in FIG. 3, the processing container 42 includes a discharge plate 64 below the discharge port 53. The discharge plate 64 is attached between the pair of guide ribs 54 a and 54 b, and extends obliquely forward and 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.

  FIG. 47 is an explanatory diagram showing the configuration of the bag adapter 120. The bag adapter 120 is formed in a rectangular frame shape having a handle 120a. The frame shape of the bag adapter 120 and the position of each bag adapter installation part 110a, 110b of the garbage processing apparatus 1 correspond to each other.

  FIG. 48 is an explanatory diagram showing the configuration of the dust storage tray 121. The trash storage tray 121 includes a handle 121a and is formed in a rectangular parallelepiped shape with an open top. The shape of the rectangular parallelepiped of the garbage storage tray 121 corresponds to the shape of the garbage storage tray installation unit 111 of the garbage processing apparatus 1.

<Division structure of processing container>
As shown in FIG. 42, a container upper case 42 c is attached to the upper part of the processing container 42. The lower unit 6 described above is combined with the container upper case 42c. The processing container 42 and the container upper case 42c are attached so as to be disassembled by screwing, for example. Thus, when the container upper case 42c shown in FIG. 38 is removed, the stirring blade 44 of the processing container 42 shown in FIG. 24 can be removed and replaced.

  An opening 42f is provided on the upper surface of the container upper case 42c, and the lower unit 6 shown in FIG. 13 is attached to the opening 42f. Here, the lower unit 6 is connected to the upper unit 5 attached to the sink 2a via a connecting member 24. Since the lower unit 6 remains on the apparatus main body side when the processing container 42 is disassembled, the processing container 42 is easily disassembled.

<Control configuration of garbage disposal device>
FIG. 49 is a block diagram illustrating a configuration example of a control system of the garbage processing apparatus 1. The system controller 92 shown in FIG. 49 constitutes an example of a control unit (means). The system controller 92 constitutes an example of a control unit, and is based on a cam position detection signal S39 output from the cam position detection sensor 39. The output of the motor 36a is controlled. The system controller 92 includes, for example, an A / D converter 92a, a CPU (Central Processing Unit) 92b, a work RAM (Random Access Memory) 92c, and a ROM (Read Only Memory) 92d. The The ROM 92d stores system program data for controlling the whole garbage disposal apparatus and information for controlling the operation mode. The RAM 92c temporarily stores control commands when the operation mode is executed. When the power is turned on, the CPU 92b reads the system program data from the ROM 92d, starts the system, and controls the entire apparatus.

  An operation unit 98 is connected to the system controller 92, and an operation signal S98 such as ON / OFF information of a power switch (not shown) and confirmation information when a foreign object is clogged is output to the system controller 92. The CPU 92b performs various motors based on the operation signal S98, a plurality of sensors 19a, 19b, 39, 51a to 51c, 61, 93 and a current / voltage conversion unit (hereinafter referred to as an IV conversion unit 68) for detecting a stirring blade motor current value. The outputs of 67, 69c, 97a, 36b, 79b (or 80c), the upper lid solenoid 13a, the PTC heater 52, the monitor 91, the buzzer 96, and the like are controlled. Eight sensors 19 a, 19 b, 39, 51 a to 51 c, 61 including a front panel open / close detection sensor 93 are connected to the system controller 92. The A / D converter 92a converts each sensor output from analog to digital and outputs data corresponding to each signal.

[Detection system]
38, when the front panel 41a is opened and closed in the cover 41 shown in FIG. 38, the sensor 93 detects the opening and closing of the front panel 41a and outputs a panel open / close detection signal S93 to the system controller 92. 24. When the cover unit 58 shown in FIG. 24 is opened or closed from the discharge port 53 shown in FIG. 31, the sensor 61 for detecting the opening / closing of the discharge port detects opening / closing of the cover unit 58 and opens / closes the discharge port. The detection signal S61 is output to the system controller 92. As a result, the CPU 92b can determine whether the cover unit 58 is opened or closed from the output of the sensor 61.

  The upper lid opening / closing detection sensors 19a and 19b (upper lid sensors 1 and 2) detect the opening and closing of the lid body 11 to the opening 9 shown in FIG. 9 and send the upper lid opening / closing detection signals S19a and S19b to the system controller 92. To be output to. In the system controller 92, the CPU 92b determines whether the lid 11 is locked based on the opening / closing detection data D19 after A / D converting the two upper lid opening / closing detection signals S19a, S19b output from the upper lid detection sensors 19a, 19b. . For example, the CPU 92b recognizes that the lid 11 is closed to the closing opening 9 when the open / close detection data D19 is sequentially detected as “10”, “00”, “11”. As a result, the system controller 92 can detect from the outputs of the upper lid detection sensors 19a and 19b whether or not the lid body 11 blocks the closing opening 9 and is locked.

  The stirring blade origin position detection sensor 51a detects the rotational position of the stirring blade 44 in the processing container 42 shown in FIG. 3, and outputs a stirring blade origin position detection signal S51a to the system controller 92. . The stirring blade bottom lid push-up position detection sensor 51b detects the push-up position of the stirring blade 44 in the processing container 42 shown in FIG. 3, and outputs the stirring blade push-up position detection signal S51b to the system controller 92. Made. Thus, the CPU 92b can determine the position of the stirring blade 44 from the outputs of the sensors 51a and 51b. The stirring blade discharge position detection sensor 51c detects the discharge position of the stirring blade 44 in the processing container 42 shown in FIG. 3, and outputs a stirring blade discharge position detection signal S51c to the system controller 92. .

  The bottom lid closing detection sensor (cam position detection sensor) 39 detects the rotational position of the bottom lid 22 with respect to the closing cylinder 21 shown in FIG. 13 and outputs a cam position detection signal S39 to the system controller 92. The As a result, the CPU 92b can identify the state of the lock cam 34 that locks and unlocks the bottom cover 22 from the output of the cam position detection sensor 39. The system controller 92 controls the motor so as to shift to the stirring operation using the cam position detection signal S39 as a trigger.

[Drive system]
The above-described system controller 92 is connected to various motors 67, 69c, 97a, an output system such as the upper lid solenoid 13a, the PTC heater 52, the monitor 91, and the buzzer 96. The system controller includes motors 67, 69c, 97a, upper lid solenoid 13a, PTC heater 52, monitor 91, buzzer 96, and the like based on the outputs of the sensors 19a, 19b, 39, 51a to 51c, 61 and a predetermined program. Is made to drive.

  The motor 69c for the blower fan is configured to input a motor drive voltage V69c from the system controller 92 and drive the blower fan 69 shown in FIG. Thus, the intermittent operation control of the blower fan 69 can be performed in the CPU 92b at the time of crushing and drying the garbage.

  The motor 97a for the exhaust fan drives the exhaust fan (not shown) by inputting a motor drive voltage V97a from the system controller 92 when discharging the granular powder. Thus, the intermittent operation control of the exhaust fan can be performed in the CPU 92b when the granular powder is discharged. Odor leakage into the room can be reduced.

  The motor 67 for the stirring blade is configured to input a motor drive voltage V67 from the system controller 92 and to reciprocate and rotate the stirring blade 44 shown in FIG. Thereby, the reciprocating rotation control and rotation control of the stirring blade 44 can be performed in the CPU 92b during the operation of the stirring blade. For example, in the system controller 92, the stirring blade 44 is moved to a position that is out of the lower projection area of the charging cylinder portion 21 of the processing container 42 and out of the rotation locus of the bottom lid 22 before the bottom lid 22 is opened. Then, the motor 67 is controlled to stop. Thereby, the stop position of the stirring plate 47 at the time of throwing in the garbage can be set at a place deviated from the area below the throwing cylinder part 21 (dust dropping area).

  In this example, regarding the rotation of the shaft portion 45 of the processing container 42, when the direction in which the stirring blade 44 meshes with the crushing blade 62 is set to the normal rotation, the system controller 92 reversely rotates the shaft portion 45 and puts the processing container 42 in The motor 67 is controlled so as to move the stirring blade 44 to a position deviating from the lower projection area of the cylindrical portion 21. Thereby, the garbage 7 can be driven to the back side of the stirring blade 44.

  Further, when the lid 11 is unlocked, the upper lid solenoid 13a shown in FIG. 49 receives the solenoid drive voltage V13a from the system controller 92 and drives the upper lid solenoid 13a shown in FIG. 11B for a moment. As a result, the user can remove the lid 11 from the closing opening 9. After unlocking the upper lid, the CPU 92b may determine that the lid 11 has been removed from the closing opening 9, and shift to another control. For example, a reciprocating rotation operation of the stirring blade 44 after the bottom lid 22 is closed, a motor intermittent operation including a rotation operation and a stop, and the like.

  The filter dust removing motor 79b (or 80c) receives the motor drive voltage V79b (or V80c) from the system controller 92 when the garbage crushing and drying operation is stopped, and the motor 79b (or FIG. 45 shown in FIG. 45) is input. The motor 80c) is driven. Thus, the filter dust removal control can be executed in the CPU 92b during filter cleaning.

  The PTC heater 52 is heated from the bottom of the processing container 42 shown in FIG. 3 by inputting the heater driving voltage V52 from the system controller 92 when the garbage is crushed and dried. As a result, the ON / OFF control of the PTC heater 52 can be executed by the CPU 92b during the intermittent stirring blade operation.

  When a foreign object is clogged, the buzzer 96 inputs an alarm signal S96 from the system controller 92 and sounds a buzzer (not shown) to notify the user of an abnormality. Thereby, when the foreign matter is clogged, the buzzer sounding control can be executed in the CPU 92b.

  50A to 50C are time charts illustrating an example of intermittent operation in the garbage processing apparatus 1. In this example, in order to suppress the power consumption of the motor 67 for driving the stirring blades, control for intermittently driving the stirring blades 44 is employed. During the stirring and drying operation, the powdered granular material is swollen and stuck to the filter 78, thereby causing the filter 78 to be clogged and reducing the exhaust air volume. In this example, the stirring operation is performed. By stopping the blower fan 69 at the same time, the filter dust removal unit 71 of the first example or the filter dust removal unit 80 of the second example described above is used by utilizing the fan stop period. 78 is scraped off to drop the granular powder adhered to the filter 78.

  In the stirring operation shown in FIG. 50A, the high level section is a stirring blade drive period T1 in which the drive motor 67 of the stirring blade 44 is energized. The low level section is a stirring blade drive stop period in which the drive motor 67 is not energized. In this example, the stirring blade driving period T1 is set to 150 seconds (2 minutes 30 seconds). In the stirring blade driving period T1, the reciprocating rotation operation and the forward rotation operation of the stirring blade 44 are performed. By performing the reciprocating rotation operation of the stirring blade 44, the paste-like dust adhered to the rotation direction surface of the stirring blade 44 is peeled off from the stirring blade 44 by the frictional force with the inner wall of the processing container during the reverse rotation. To fall.

  In the fan drive shown in FIG. 50B, a high level section is a fan drive period in which the blower fan motor 69b of the blower fan 69 is energized, and a low level section is a fan stop period in which the blower fan 69b is in a non-energized state. T2. In this example, the fan stop period T2 is set to 30 seconds. Of course, the set value is not limited to 30 seconds.

  In the filter scraping operation shown in FIG. 50C, the low level section is a filter cleaning non-execution period in which the filter dust removal motor 79b (or 80c) is in a non-energized state, and the high level section is the motor 79b. (Or 80c) is the filter cleaning period T3 during which power is supplied. The filter cleaning period T3 is set to 5 seconds, and the granular powder material is scraped off from the filter 78. The filter cleaning period T3 is a stirring blade drive stop period, and is executed at a timing that predicts the time during which each fan stops completely and the air flow stops within the fan stop period set to T2 = 30 seconds. Is done.

  At this time, when the garbage processing apparatus 1 includes the filter dust removal unit 71 of the first example, the motor drive voltage V79a is output from the system controller 92 to the filter dust removal motor 79b. By driving the motor 79b shown in FIG. 43A, the cam 77 rotates, and the L-shaped portion at the tip of the plate 79 supported by the shaft 79a hits the filter 78, and the granular powder material adhered thereto. Scrap off. Thereby, the filter 78 can be automatically cleaned.

  When the garbage processing apparatus 1 includes the filter dust removal unit 80 of the second example, the motor 80c for filter dust removal outputs a motor drive voltage V80c from the system controller 92. When the motor 80c shown in FIG. 45 is driven, the shaft 80a rotates and an impact is applied to the filter 78 by the brush 80b to scrape off the attached granular powder. Thereby, the filter 78 can be automatically cleaned.

  After the granular powder is dropped, the motor driving signal S69 is output to the blower fan 69 again as shown in FIG. At this time, since the stirring operation shown in FIG. 50A is stopped at a low level, the granular powder does not soar, the granular powder does not adhere to the filter 78, the exhaust air volume increases, and the drying performance is improved. become able to.

<Air volume control by fan>
When the amount of dust in the processing container 42 increases and becomes full, the discharge operation is promoted. However, the amount of dust scraped up by the stirring blade 44 increases as the amount of dust increases. . When the amount of dust processing increases, the pressure loss of the blower fan 69 increases. Also, pressure loss increases when dirt is deposited in the exhaust pipe. Normally, when the pressure loss increases, the rotational speed of the blower fan 69 increases, so that the system controller 92 executes the blower control.

  FIG. 51 is a table showing an example of a control table in the system controller 92. The control table shown in FIG. 51 is described in the ROM 92d in the system controller 92, for example. According to this control table, when the amount of dust is large, contents are set such that the rotation speed is “large” and the air volume is “large”. When the amount of dust is medium, the contents are set so that the rotation speed is “medium” and the air volume is “medium”. When the amount of dust is small, the contents are set so that the rotation speed is “small” and the air volume is “small”. The system controller 92 executes the automatic operation mode based on the control table.

  In this example, the rotational speed of the blower fan 69 is detected, and the rotational speed of the blower fan 69 is controlled so that a constant air volume can be maintained with reference to the control table shown in FIG. For example, after selecting the rotation speed for driving the blower fan 69 with the specified air volume from the air volume specified in the control table and the current applied voltage, the selected rotation speed is compared with the actual rotation speed, and the rotation is performed. The motor drive voltage V69a is controlled so that the numbers are the same.

<Intake and exhaust operation>
Next, the intake / exhaust operation in the garbage processing apparatus 1 will be described with reference to FIGS. FIG. 52 is a plan view showing the flow of intake and exhaust air in the garbage processing apparatus 1 in a state where the front panel 41a and the discharge port 53 are closed and only the blower fan 69 is driven. 53 is a cross-sectional view showing the flow of air in the processing container 42 in a state where the front panel 41a and the discharge port 53 are closed and only the blower fan 69 is driven.

  First, when the blower fan 69 is driven, air outside the cabinet 2b is sucked into the cabinet 2b from the gallery 2e formed on the door 2c of the cabinet 2b as shown by an arrow A in FIG. Further, as shown by an arrow B in FIG. 2, air outside the cabinet 2b is sucked into the cabinet 2b through the air inlet 2f and the air vent 2g formed in the kicked portion 2d of the cabinet 2b. As shown in the arrow C in FIG. 2 and the arrow h in FIG. 52, the air in the cabinet 2b is sucked into the cover 41 from the air inlet 73 of the front panel 41a, and blown from the blower fan suction port 69a. 69 is inhaled. The air sucked into the blower fan 69 is blown into the blower duct 70 from the blower fan exhaust port 69b as shown by an arrow i in FIG. 52, and blown into the process vessel 42 from the process vessel intake port 42u.

  As shown by arrows j in FIG. 52 and arrows in FIG. 53, the air blown into the processing container 42 is flown by a rectifying plate 42j and an extending portion 42jj provided in the processing container inlet 42u in the processing container 42. After flowing downward in the stirring / drying space inside the processing container 42, it flows toward an exhaust port 74 provided in the upper part of the processing container 42. At this time, the air flow inside the processing container 42 follows a semi-cylindrical shape inside the processing container 42. As described above, even when the processing container intake port 42u is provided on the upper surface of the container upper case 42c and the rectifying plate 42j and the extending portion 42jj are not provided, the air blown into the processing container 42 is Similarly to the example shown in FIG. 52, after flowing downward in the stirring / drying space inside the processing container 42, it flows toward the exhaust port 74 provided in the upper part of the processing container 42. The air that has flowed to the exhaust port 74 flows into the drain pipe 87 through the exhaust duct A85, the elbow duct 85a, and the exhaust duct B86, as indicated by arrows k and l in FIG.

  As described above, in the garbage processing apparatus 1, air is reliably blown down to the agitation / drying space inside the processing container 42. Thereby, in the crushing drying operation | movement mentioned later, ventilation is reliably performed with respect to the garbage located in the bottom part of the processing container 42, and it becomes possible to perform the drying process of a garbage with high efficiency. Moreover, in the garbage processing apparatus 1, the lower half of the processing container 42 is formed in a semi-cylindrical shape. For this reason, compared with the case where the inside of a processing container is formed in the rectangular parallelepiped, for example, the flow of the air in the processing container 42 becomes smooth, and it becomes possible to perform the drying process of garbage with high efficiency.

  Furthermore, in the garbage processing apparatus 1, as described above, since the processing container intake port 42c and the exhaust port 74 are provided in the upper part of the processing container 42, the processing container intake port 42c and the exhaust port 74 are formed by garbage. It becomes possible to prevent clogging.

  The garbage disposal apparatus 1 includes a louver 2e of the door c of the cabinet 2b under the sink 2a and an intake 2f of the kick-in part 2d as intakes for sucking air outside the cabinet into the cabinet. As a result, the pressure loss when sucking air outside the cabinet 2b is reduced compared to a garbage disposal device installed in a cabinet that does not include the louver 2e and the intake port 2f, and is necessary for the intake of the garbage disposal device 1. Air volume is secured. Thereby, the fall of the efficiency of the crushing drying process of the garbage processing apparatus 1 mentioned later can be prevented. In addition, it is possible to reduce wind noise during intake as compared with a garbage disposal device installed in a cabinet that does not include the louver 2e and the intake port 2f.

  Moreover, in the garbage processing apparatus 1, the air exhausted from the processing container 42 flows to the drain pipe 87 through the exhaust duct A85, the elbow duct 85a, and the exhaust duct B86. Thereby, it is possible to prevent the odor of the garbage 7 from leaking into the living room or the like. Furthermore, as described above, in the garbage processing apparatus 1, since the air volume necessary for intake is secured, exhaust is performed with the necessary air volume.

  Furthermore, while the crushing and drying operation described later is stopped, the air in the processing container 42 can be ventilated by periodically sucking and exhausting the processing container 42 by the blower fan 69.

  Subsequently, an operation example in the garbage processing apparatus 1 will be described with reference to FIGS. 16A, 18, 19, and 54 to 58. FIG. 54 is a flowchart showing an operation example when throwing in garbage and closing the bottom lid. 55 to 57 are cross-sectional views showing operation examples (Nos. 1 to 3) when the bottom cover is closed. In this example, an operation example in which the top lid is locked in steps SA1 to SA4, the bottom lid 22 is unlocked in steps SA5 and SA6, and the bottom lid 22 is locked in steps SA7 to SA9 will be described.

  In this example, after the lid 11 is locked to the input opening 9, the bottom lid is unlocked. Further, the garbage crushing and drying apparatus 4 is provided with a stirring blade 44 for crushing the garbage 7, the stirring blade 44 is provided with a rib 44 a, and the bottom lid 22 separated from the charging cylinder portion 21 of the lower unit 6 is When the bottom cover 22 is closed, the rib 44a of the stirring blade 44 is pressed against the bottom cover 22 to close it.

<Garbage input operation>
First, in the state where the lid 11 is opened, the bottom lid 22 closes the lower end of the charging cylinder portion 21 as shown in FIG. Further, as shown in FIG. 13, the pushing portion 29 of the bottom lid 22 is pushed up by the pushing portion 34 a of the lock cam 34. As a result, as shown in FIG. 15, the seal member 30 attached to the bottom cover 22 is in a state where the packing 30 a is pressed against the seal surface 31 of the input cylinder part 21.

  When the garbage 7 is thrown from the throwing opening 9 connected to the throwing cylinder part 21, the thrown garbage is collected on the bottom cover 22. As described above, since the sealing member 30 of the bottom lid 22 is pressed against the sealing surface 31 of the charging cylinder portion 21, leakage of moisture contained in raw garbage from the bottom lid 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. 16A, when the bottom lid 22 is closed, the portion where the sealing member 30 is exposed on the side of the closing opening 9 is the clearance portion between the lid portion 27 of the bottom lid 22 and the charging cylinder portion 21. is there. For this reason, even if a fork or the like is mistakenly inserted, the seal member 30 is not damaged.

[Process when throwing in garbage]
In order to process the garbage thrown into the loading opening 9 with the garbage processing apparatus 1, first, the closing opening 9 is closed with the lid 11 in step SA1 of the flowchart shown in FIG. At this time, when the user fits the lid body 11 into the insertion opening 9 and rotates the lid body 11 in a predetermined direction, the latching claw 16 of the upper lid lock mechanism 12 fits into the latching groove 11 b of the lid body 11. Rotation is regulated. 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.

  In step SA2, the sensors 19a and 19b detect the position of the lid 11. For example, the upper lid detection sensor 19a detects the magnet 18a of the lid 11 at a position where the latching claw 16 fits into the latching groove 11b of the lid 11. Further, the lid 11 is rotated, and the upper lid detection sensor 19b is rotated to a position where both the magnet 18b is detected. The upper lid detection sensor 19a outputs a position detection signal S19a to the system controller 92, and the upper lid detection sensor 19b outputs a position detection signal S19b to the system controller 92. When the system controller 92 detects “1, 00, 11” with respect to the position detection signals S19a and s19b, the system controller 92 recognizes that the lid 11 is fitted in the opening insertion portion 9 and locked in the closed state.

  When the system controller 92 detects the lock of the lid 11 by the upper lid detection sensors 19a and 19b, the system controller 92 detects the position of the stirring blade 44 from the output of the origin position detection sensor 51a in step SA3. That is, when the stirring blade 44 is rotating, the origin position detection sensor 51a detects the stirring blade 44, so the rotation of the motor 67 is stopped and the stirring blade 44 is stopped at the origin position O ″.

  Next, the system controller 92 stops the rotation of the fan motor that drives the blower fan 69 in step SA4. In this example, when the rotation of the blower 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 (not shown) is closed by the motor, and the PTC heater 52 is stopped.

  When the upper controller 11a, 19b detects that the lid 11 is locked, the system controller 92 starts driving the motor 36a after a predetermined time has elapsed. Here, the system controller 92 performs the above-described processing of Step SA3 and Step SA4 after a predetermined time elapses after the lock of the lid body 11 is detected by the upper lid detection sensors 19a and 19b.

[When opening the bottom cover]
Next, in step SA5 shown in FIG. 54, the bottom cover lock is released by the lock cam. As shown in FIG. 18, in the state where the lock cam 34 is at the origin position O ′, the push-up portion 34a abuts against the bottom lid 22 and is pushed up as shown in FIG. 16A. Further, the system controller 92 detects the lock of the lid 11 by the upper lid detection sensors 19a and 19b, and when a predetermined time has elapsed, the system controller 92 drives the motor 36a to rotate the lock cam 34 in the direction of arrow a and open the bottom lid 22. At this time, the lock cam 34 is connected to the motor 36a via the drive shaft 35 'and the reduction gear 36b as shown in FIG. 3, so that when the motor 36a rotates, the lock cam 34 also rotates.

  When the lock cam 34 is rotated about 130 degrees in the direction of the arrow a from the origin position O 'by driving the motor 36a, the bottom cover 22 is separated from the push-up portion 34a. Thereby, the lock | rock in the closed state of the bottom cover 22 by the lock cam 34 is cancelled | released, and the bottom cover 22 opens with the axial part 28 as a fulcrum by the dead weight and the weight of garbage.

  FIG. 55 shows a state where the bottom cover 22 is opened. The bottom cover 22 after unlocking shown in FIG. 55 is opened in a state of hanging in a substantially vertical direction. The garbage on the bottom lid 22 is put into the processing container 42, and the bottom lid 22 hangs down in the processing container 42. The garbage 7 has fallen behind the stirring blade 44. At this time, since the stirring blade 44 is stopped at the origin position O ″, the bottom lid 22 does not contact the stirring blade 44 during the opening operation of the bottom lid 22.

  Normally, when the bottom cover 22 is unlocked by the lock cam 34, the bottom cover 22 is automatically opened by its own weight, as shown in FIG. 16B. Conceivable. Therefore, in step SA6, the bottom cover 22 is forcibly opened by the lock cam 34 (bottom cover forced lock release). FIG. 19 is a bottom view showing a state in which the lock cam 34 is rotated 180 ° from the origin position O ′ in the direction of arrow a. As shown in FIG. 19, when the lock cam 34 is rotated 180 ° in the direction of the arrow a from the origin position O ′, the pressing surface 34 b 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 seal member 30 can be forcibly opened even if it is not opened by its own weight due to sticking or the like.

  When the system controller 92 rotates the lock cam 34 by 180 ° from the origin position O ′ in the direction of the arrow a, the system controller 92 stops driving the motor 36 a. Here, the rotation angle of the lock cam 34 is controlled by the rotation phase of the motor 36 a after the origin position O ′ is detected by the cam position detection sensor 39. At this time, the lid 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 lid 11 is locked by the upper lid detection sensors 19a and 19b until the motor 36a starts to be driven and the bottom lid 22 is opened is set to about 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.

[Bottom lid closing operation]
Next, in step SA7, the system controller 92 rotates the lock cam 34 from the origin position O ′ by 180 ° in the direction of the arrow a to stop driving the motor 36a. Further, the stirring blade 44 is rotated by the motor 67 from the position shown in FIG. 55 in the direction of the arrow c shown in FIG. That is, when the agitating blade 44 at the origin position O ″ is rotated in the direction of the arrow c with the bottom lid 22 open, the bottom lid 22 exists in the rotation trajectory of the agitating blade 44. 44a contacts the push-up convex portion 32 of the bottom lid 22. Further, as shown in Fig. 57, when the stirring blade 44 is rotated until it is detected by the bottom lid push-up detection sensor 51b, the stirring plate 47 of the stirring blade 44 is moved. The bottom cover 22 is pushed up, and the bottom cover 22 is closed by a rotating operation with the shaft portion 28 as a fulcrum.

  Continuing with this operation, in step SA8, the system controller 92 rotates the motor 36a when the bottom lid push-up detection sensor 51b detects the stirring blade 44 and stops the rotation of the motor 67, and the lock cam 34 is moved to FIG. Rotate in the indicated arrow b direction. As a result, the lock cam 34 shifts from the open state shown in FIG. 19 to the closed state shown in FIG. At this time, when the lock cam 34 rotates in the arrow b direction from the open state shown in FIG. 19 to the closed state shown in FIG. 18, the pushing surface 34 a of the bottom lid 22 contacts the pressing portion 29 of the bottom lid 22. The bottom cover 22 is pushed up. Then, when the lock cam 34 rotates in the arrow b direction to the closed state shown in FIG. 18, the push-up operation by the push-up surface 34 is completed. In step SA9, the operation is terminated by returning to the lock cam origin.

[Exception handling]
The system controller 92 stops the rotation of the motor 67 when the bottom lid push-up detection sensor 51b detects the stirring blade 44. As a result, the bottom cover 22 closes the charging cylinder portion 21 while being supported by the stirring blade 44. Here, if the bottom lid push-up detection sensor 51b does not detect the stirring blade 44 even after a predetermined time has elapsed after the rotation of the motor 67 is started, the system controller 92 reverses the motor 67 by a predetermined amount to rotate the stirring blade. 44 is returned to the origin position O ′ or slightly beyond the origin position O ′, and retry is performed. If the bottom lid push-up detection sensor 51b does not detect the stirring blade 44 even after a plurality of retries, an alarm is generated and an error occurs.

  At the time of this error, it is considered that the bottom lid 22 is in an open state, so the system controller 92 keeps the lid 11 locked in the closed state. As shown in FIGS. 3 and 4, a drainage channel 94 led to the drainage port 8 is formed around the opening 9 of the sink 2 a, and the drainage channel 94 is blocked by the lid 11. Therefore, even when the lid 11 is closed, the function as a normal sink is achieved.

  FIG. 58 is a cross-sectional view showing an example of the stirring operation in the processing container. The stirring blade 44 of the processing container 42 shown in FIG. 58 is controlled to reciprocate and rotate. During the agitating blade intermittent operation described above, the standby position when the agitating blade 44 is stopped is at a position α that is retracted like the agitating blade 44 shown by a two-dot chain line in FIG. As a condition of the standby position, it is mentioned that the air blown into the stirring blade 44 hits the garbage 7 without being obstructed, and this involves the bottom lid 22 when the bottom lid 22 is closed. This is because the dust on the stirring blade 44 does not get in the way during the closing operation of the stirring blade 44. Note that if the uppermost position (hereinafter also referred to as the return point) β of the crushing blade 62 is the standby position of the stirring blade 44, In the stop position α, it is not necessary to reverse the stirring blade 44.

  In this example, the operating range of the stirring blade 44 is narrowed and reciprocally rotated. For example, when the rotation range of the stirring blade 44 is θαβ and θαβ = 120 °, the stirring blade 44 has a rotation operation range of 240 ° per reciprocal rotation operation. By limiting the operation range, the number of times that the garbage 7 passes through the crushing blade 62 is increased (the crushing speed is increased) as compared with the case where the stirring blade 44 is rotated 360 °, so that the garbage 7 can be efficiently crushed. It becomes like this.

  In this example, the reciprocating rotation of the stirring blade 44 causes the lower portion of the garbage 7 in the processing container 42 having a semi-cylindrical shape to stick to the stirring blade 44 by the frictional force between the inner wall of the processing container 42. Garbage changes in the opposite direction. Thereby, the garbage 7 stuck on the stirring blade 44 can be peeled off from the stirring blade 44.

  In this example, in order to stir again the garbage 7 that has fallen backward, a sequence that rotates the stirring blade 44 once every predetermined time (for example, 30 seconds) is set up. As described above, by increasing the crushing efficiency, it is not necessary to always operate the stirring blade 44, and the intermittent operation can be performed in a certain time (for example, 150 seconds).

  Thus, by rotating the stirring blade 44 back and forth within a narrow operating range, the number of times that the garbage passes through the crushing blade 62 per unit time can be increased, and the crushing speed can be increased in total. it can. The operation range of the stirring blade 44 is set to the return position β up to almost horizontal, and a structure in which a large amount of dust is not dropped on the rear side of the stirring blade 44 can be adopted. The lower side is configured to return the dust that has fallen rearward from the gap between the stirring blades 44 to the front of the stirring blades 44 by rotating the stirring blades 44 to a position set as the standby position α from directly below the vertical position. Can do.

<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 system controller 92 supplies the heater driving voltage V52 to the PTC heater 52 to turn it on, and heats the processing container 42. In addition, the motor driving voltage V69b is supplied to the motor 69b to rotate the blower fan 69, and air blowing is started between the shafts 48a to 48e of the stirring blade body 46 of the stirring blade 44. Further, the rotation of the motor 67 is started, and the stirring blade 44 is rotated in the direction of arrow c.

  When the agitating blade 44 is reciprocated in the direction of the arrow c, the garbage in the processing container 42 is scraped up by the agitating blade body 46 while receiving the air that has passed through the shafts 48a to 48e. When the stirring blade body 46 of the stirring blade 44 passes through the crushing blade 62 provided in the cover unit 58, the crushing blade 62 passes through the gap between the stirring plates 47 of the stirring blade body 46. The raised garbage is crushed by the crushing blade 62. Thereafter, the stirring blade 44 is controlled to rotate once.

  Further, since a plurality of crushing blades 62 are provided along the axial direction of the stirring blade 44, the garbage can be crushed finely. Furthermore, since the positions of the crushing blades 62 are also shifted with respect to the circumferential direction, for example, an event in which one object is simultaneously cut by the plurality of crushing blades 62 is unlikely to occur, and an excessive force is applied to the stirring blade 44. Prevent joining.

  Thus, by rotating the agitating blade 44 after reciprocatingly rotating, the garbage is agitated in the processing container 42 and the moisture is evaporated by the air passing through the shafts 48a to 48e 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 into the processing container 42 into warm air, a heater is provided in the air passage from the air blowing fan 69 shown in FIG. However, by using the PTC heater 52 attached to the processing container 42, drying can be promoted by heating raw garbage in the processing container 42 while blowing air at room temperature. 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 downstream drainage pipe 87 through the exhaust duct A85 and the exhaust duct B86, as indicated by arrows k and l in FIG. 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, through the filter unit 75, dry dust powder that has been crushed and dried is prevented from being discharged together with the exhaust gas.

  As described above, by providing the filter unit 75 with the L-shaped plate 79 that can be automatically cleaned, the filter 78 can be cleaned without removing the filter unit 75, and clogging of the filter 78 can be prevented. it can. Further, the plate 79 may be provided, and the filter 78 may be detachable so as to be washable.

  In addition, since the exhaust from the processing container 42 is performed downstream of the drain trap 84, the sewage does not normally flow backward. However, when the drain pipe 87 is clogged, the sewage may flow backward. For this reason, a sensor for detecting the inflow of sewage is provided in the path from the check valve 76 to the drain pipe. If the sewage flows back, the check valve 76 is closed and the sewage into the processing container 42 is closed. Prevent backflow.

  Thus, according to the garbage processing apparatus 1 provided with the stirring operation mechanism with reciprocating rotation operation and rotation operation, the system controller 92 is based on the uppermost blade portion 62a of the crushing blade 62 (return point β). Then, the motor 67 is controlled so that the stirring blade 44 reciprocates. As a result, by setting the upper position of the operating range θαβ of the stirring blade 44 to the horizontal position, large litter can be prevented from dropping from a high position, so that the impact sound of falling large litter is prevented and the main body of the apparatus is silenced. I can do it now.

  Thus, according to the garbage processing apparatus 1 provided with the garbage crushing and drying apparatus 4, the system controller 92 reciprocally rotates the stirring blade 44 in a predetermined region including the crushing blade 62, and after a predetermined time, The motor 67 is controlled so as to rotate the stirring blade 44 in the processing container 42.

  Accordingly, the number of times that the garbage 7 is sandwiched between the crushing blade 62 and the stirring blade 44 and is crushed per unit time is determined by rotating the stirring blade 44 in the processing vessel 42 during all the time. Since the amount of waste 7 can be increased as compared with the case of crushing the garbage 7, the garbage 7 can be efficiently crushed powder. Moreover, compared to the conventional method, the amount of garbage 7 that is placed on the stirring blade 44 and does not crush can be reduced, and the processing time per unit amount can be shortened. Thereby, the dry-type garbage processing apparatus 1 provided with the high crushing drying function can be provided now.

  Moreover, according to the garbage processing apparatus 1 provided with the garbage crushing and drying apparatus 4, when the garbage 7 is put into the processing container 42, the system controller 92 is configured to dispose the processing container before the bottom cover 22 is opened. The motor 67 is controlled so that the stirring blades 44 are moved to a position where they are out of the lower projection region of the input cylinder portion 42 and out of the rotation locus of the bottom cover 22 and stopped.

  Therefore, the opening operation of the bottom cover 22 can be performed without hindrance, and more garbage 7 can be thrown into the lower projection area of the throwing cylinder part 21. As a result, the existing garbage 7 in the processing container 42 can be avoided from the input area, the space for storing the garbage can be increased, and new garbage 7 can be stored in the lowermost part of the processing container 42.

<Detection of foreign matter and amount of dust in processing container>
FIG. 59 is a block diagram illustrating a configuration example of a dust amount detection and foreign matter detection system. 59 includes an IV conversion unit 68, a monitor 91, a system controller 92, and an operation unit 98.

  The IV conversion unit 68 constitutes an example of a detection unit, is connected to a motor 67 for a stirring blade, detects a motor current Im flowing into the motor 67, and outputs an analog detection voltage Vm. An analog / digital (hereinafter referred to as A / D) converter 92a is connected to the IV conversion unit 68, and the detection voltage Vm is A / D converted to output current information Dm to the CPU 92b. The ROM 92d stores first to fourth threshold data Dth1 to Dth4. The IV conversion unit 68 and the system controller 92 are examples of detection means. The IV conversion unit 68 is an example of a measurement unit, and the system controller 92 is an example of a calculation unit. The monitor 91 is an example of a display device.

  First, the foreign object detection function will be described. In this example, since hard objects such as bird bones are also crushed, the crushed objects repeat the crushing operation several times. Only when the motor lock phenomenon of the motor 67 is detected continuously, the energization to the motor 67 is stopped and the stirring blade 44 is stopped. At this time, since it is difficult to remove the foreign matter while it is sandwiched between the crushing blade 62 and the stirring blade 44, a function (structure) is adopted that reverses the stirring blade 44 to a position where the foreign matter can be easily taken out.

  The system controller 92 first compares the current information Dm obtained from the IV converter 68 via the A / D converter 92a and the set first threshold data Dth1, and current information (value) exceeding the threshold data Dth1. The number of continuous detections of Dm is detected. Thereafter, the number of continuous current information Dm is compared with the set second threshold data Dth2, and the motor 67 is stopped when the number of continuous current information Dm exceeds the threshold data Dth2. This is because it is assumed that a foreign object such as a spoon or chopstick is caught between the stirring blade 44 and the crushing blade 62a. Then, the system controller 92 performs processing to output an alarm to the monitor 91 or the like or to sound the buzzer 96. The monitor 91 is provided on the operation panel surface of the cover 41, for example.

  In this example, when the number of continuous current information Dm exceeds the threshold data Dth2, the system controller 92 controls the motor 67 to stop the stirring blade 44 at a position away from the crushing blade 62 region. Here, when the discharge port 53 of the garbage processing apparatus 1 is directly facing the right hand, the counterclockwise direction is the forward rotation and the clockwise direction is the reverse rotation with respect to the rotation of the shaft portion 45 of the processing container 42. When the stirring blade 44 is stopped, the system controller 92 rotates the shaft portion 45 in the reverse direction when the number of continuous current information Dm exceeds the second threshold data, and stirs it at a position away from the region of the crushing blade 62. The wings 44 are stopped. This is to make it easier to remove foreign matters such as spoons and chopsticks sandwiched between the stirring blade 44 and the crushing blade 62a. After removing the foreign matter, the user operates the operation unit 98 to output a transmission signal S98 indicating the completion of the foreign matter removal to the system controller 92. As described above, when the current Im to the stirring blade driving motor 67 is read and exceeds the threshold value Dth2 continuously, the motor 67 can be stopped.

  Next, the dust amount detection function will be described. FIG. 60 is an explanatory diagram showing the change over time of the current information Dm of the motor 67. FIG. As described above, in the crushing and stirring operation for garbage, the reciprocating and rotating operations of the stirring blade 44 are periodically performed. Therefore, the current information Dm during the crushing and stirring operation changes periodically as shown in FIG. Further, the motor current Im flowing into the motor 67 becomes maximum when the reciprocating rotation operation is started. For this reason, as indicated by K in FIG. 60, the value of the current information Dm is maximized in each cycle before and after the stirring blade 44 transitions from the rotational operation to the reciprocating rotational operation.

  Further, as the amount of the garbage 7 in the processing container 42 increases, the load on the stirring blade 44 during the crushing and drying operation also increases. For this reason, when the amount of the garbage 7 in the processing container 42 increases, the maximum value of the current information Dm in each cycle also becomes a large value.

  The system controller 92 compares the integrated value Da for the predetermined period of the maximum value of the current information Dm in each period with the third threshold data Dth3. When the integrated value Da is larger than the threshold value data Dth3, the system controller 92 notifies the user that the amount of the garbage 7 in the processing container 42 is equal to or greater than a predetermined amount. And the like, and the buzzer 96 is sounded. Accordingly, the user recognizes that the amount of the garbage 7 in the processing container 42 is equal to or greater than a predetermined amount, and discharges the garbage 7 in the processing container 42 before introducing new garbage. It becomes possible.

  After the integrated value Da becomes larger than the threshold data Dth3, the system controller 92 compares the integrated value Da with the fourth threshold data Dth4. When the integrated value Da is larger than the fourth threshold data Dth4, the system controller 92 outputs an alarm to the monitor 91 or the like, or displays a buzzer 96 on the assumption that the garbage 7 in the processing container 42 is full. A process such as ringing is performed, and a new garbage input operation is prohibited. Accordingly, the user recognizes that the garbage 7 in the processing container 42 is full, and can discharge the garbage 7 in the processing container 42 after the crushing and drying process is completed. In addition, it is possible to prevent the garbage exceeding the specified amount from being thrown into the processing container 42.

  According to the garbage processing apparatus 1 according to the present invention, the motor current Im of the motor 67 of the stirring blade 44 that stirs the garbage 7 in the processing container 42 is measured, and the inside of the processing container 42 is measured based on the measurement result. The amount of garbage 7 is calculated. This makes it possible to detect the amount of garbage 7 in the processing container 42 with a smaller number of parts compared to a conventional garbage processing apparatus that uses a separate mechanical sensor. Further, by not using a mechanical sensor, it is possible to prevent a decrease in the reliability of the apparatus.

<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.

  As shown in FIG. 37A, when the cover unit 58 is closed and the shaft 60a is fitted into the hook-shaped hook portion 57, the cover unit 58 is in a locked state with the discharge port 53 closed. Further, when the shaft 60 a is fitted into the hook portion 57, the system controller 92 can detect that the cover unit 58 is closed from the output of the discharge port opening / closing detection sensor 61.

  As shown by the arrow p in FIG. 37B, when the handle 60 is pushed down from the state where the cover unit 58 is locked, the shaft 60a moves upward in the shaft groove 42h as shown by the arrow q, and the shaft 60a The hook portion 57 is unlocked. As a result, as shown by the arrow in FIG. 37C, the cover unit 58 can be rotated to open the discharge port 53. At this time, the system controller 92 can detect that the cover unit 58 is open from the output of the outlet opening / closing detection sensor 61.

  As described above, for example, the cover unit rotation shaft 55 provided in the suspension base portion 42g includes fixing means for fixing the cover unit 58 at a predetermined position, such as a rotary damper and a one-way hinge. It is fixed at an arbitrary position such as a discharge position shown. For this reason, when the cover unit 58 is opened, the cover unit 58 is not closed due to its own weight, and it is possible to prevent the hand from touching the crushing blade 62 or the hand holding the cover unit 58. It becomes.

  In the discharge operation described later, the cover unit 58 is fixed at the discharge position. When taking out a spoon or the like that has been accidentally dropped into the processing container 42, the cover unit 58 is removed from the processing container 42 by the method described above.

  As shown in FIG. 31, in the state where the cover unit 58 is at the discharge position, a slight gap is formed between the lower part of the opened cover unit 58 and the discharge port 53. The crushing blade 62 cannot be touched.

  Further, as described above, the cover unit 58 is configured to be removable from the processing container 42, and when the crushing blade 62 is replaced, the cover unit 58 is replaced. Also, the cover unit 58 is removed from the processing container 42 when taking out a foreign object such as a spoon.

<Discharge operation>
FIG. 61 is a flowchart showing the flow of processing during discharge. As shown in FIG. 38, when the sensor 93 detects that the front panel 41a of the cover 41 has been opened (step B1), the system controller 92 detects the position of the stirring blade 44 from the output of the origin position detection sensor 51a. . That is, when the stirring blade 44 is rotating, when the origin position detection sensor 51a detects the stirring blade 44, the rotation of the stirring blade motor 67 is stopped and the stirring blade 44 is stopped at the origin position (step B2). .

  In addition, the system controller 92 stops the rotation of the blower fan 69. In this example, when the rotation of the blower fan 69 is stopped, the check valve 72 is closed. Further, the system controller 92 stops the PTC heater 52 and rotates the exhaust fan 97. (Step B3). When the front panel 41a is opened and the above-described closing operation is being performed, the discharging operation cannot be performed, so an alarm such as a buzzer or a lamp is issued.

  62 and 63 are explanatory views showing a state in which the bag adapter 120 to which the bag 101 is attached is installed in the bag adapter installation unit 110 (110a, 110b). 62 is a perspective view, and FIG. 63 is a cross-sectional view. FIG. 64 is a cross-sectional view showing a state in which the trash storage tray 121 is installed in the trash storage tray installation unit 111. After the completion of step B3, as shown in FIGS. 62 to 64, the bag adapter 120 to which the bag 101 is attached or the garbage storage tray 121 is installed in the garbage processing apparatus 1 (step B4).

  FIG. 65 is a sectional view showing a state in which the cover unit 58 is opened with the bag adapter 120 to which the bag 101 is attached, and FIG. 66 is a view in which the cover unit 58 is opened with the dust storage tray 121 installed. It is sectional drawing which shows a state. After step B4, as shown in FIGS. 65 and 66, the cover unit 58 is opened to the discharge position shown in FIG. Here, the system controller 92 detects from the output of the outlet opening / closing detection sensor 61 that the shaft 60a has been detached from the hook portion 57.

  65 and 66, in the state where the bag adapter 120 to which the bag 101 is attached and the dust storage tray 121 are installed, the end portions of the bag adapter 120 and the dust storage tray 121 on the processing container 42 side are It is located on the back side of the discharge plate 64 provided below the discharge port 53. Thereby, when the cover unit 58 is opened, dry dust powder falling from the discharge port 53 and the cover unit 58 can be prevented from being scattered around without being stored in the bag 101 or the dust storage tray 121. .

  67 and 68 are explanatory views showing a state in which the bag adapter 120 is fixed to the garbage processing apparatus 1. 67 is a perspective view, and FIG. 68 is a cross-sectional view. When the bag adapter 120 to which the bag 101 is attached is installed after the end of step B5, as shown in FIGS. 67 and 68, the bag adapter 120 to which the bag 101 is attached is fixed (step B6, step B7). . In a state where the end of the bag adapter 120 on the processing container 42 side is hooked on the discharge plate 64, each handle rib 54 and the cover unit 58 are covered with the bag 101, the handle 120 a side is lifted, and the bag is fixed by a fixing means (not shown). The adapter 120 is fixed.

  When using the trash storage tray 121, the user presses the discharge button provided on the operation unit 98 after step B6, and when using the bag adapter 120 with the bag 101 attached after step B7 (step B8).

  In the garbage processing apparatus 1, for example, the system controller 92 executes the dust discharge mode only while the user presses the discharge button of the operation unit 98 (step B9). Here, the dust discharge mode is executed when both unlocking of the cover unit 58 by the handle 60 and pressing of the discharge button are detected.

  69 to 71 are explanatory diagrams of the operation in the dust discharge mode. In the dust discharge mode, the system controller 92 drives the stirring blade motor 67 to first rotate the stirring blade 44 at the origin position in the direction of the arrow as shown in FIG. The system controller 92 uses the detection signal from the discharge position detection sensor 51 c so that the amount of rotation of the stirring blade 44 stops at a position where the tip of the stirring blade body 46 does not exceed the lower end of the discharge port 53. Control the rotation of Here, without using the discharge position detection sensor 51c, for example, measurement means for measuring the drive time of the stirring blade 44, the detection result of the position of the stirring blade 44 by the origin position detection sensor 51a, and the stirring blade 44 from the origin position. The rotation amount of the agitating blade 44 may be controlled by controlling the driving time of the agitating blade 44 by calculating means for discriminating the position of the agitating blade 44 from the measurement result of the rotational driving time. This stop position is referred to as a dust discharge position.

  When the stirring 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 vessel 42 is lifted up by the stirring blade body 46 of the stirring blade 44 and is discharged to the discharge port. 53 is discharged.

  At this time, as shown in FIGS. 66 and 68, since the bag adapter 120 or the garbage storage tray 121 to which the bag 101 is attached is installed in the discharge port 53, the dry dust powder discharged from the discharge port 53 is It is stored in the bag 101 or the trash storage tray 121.

  Further, by providing the discharge plate 64 below the discharge port 53 and the guide ribs 54 on both sides of the discharge port 53, it is possible that the dry dust powder does not enter the bag 101 or the dust storage tray 121 and is scattered outside during the discharge operation. It is preventing.

  When the system controller 92 rotates the stirring blade 44 from the origin position to the dust discharge position, the system controller 92 reverses the stirring blade motor 67 and rotates the stirring blade 44 by a predetermined amount in the direction of the arrow as shown in FIG. As shown in FIG. 71, the system controller 92 controls the rotation amount of the stirring blade 44 by controlling, for example, the drive time so that the rotation amount of the stirring 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 the reciprocating rotation operation from the dust discharge position to the return position a plurality of times, then stops the stirring blade 44 at the origin position, and indicates that the dust discharge operation has been completed with a buzzer or a lamp. The user is notified (step B10).

  In this manner, by performing the reciprocating rotation of the stirring 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 rotation of the stirring blade 44 is between about 90 degrees.

  As described above, in the garbage processing apparatus 1, the stirrer blade 44 is placed in a position where the tip of the stirrer blade main body 46 does not exceed the lower end of the discharge port 53 in the dust discharge mode. It does not pass through the range of the opening of the discharge port 53. Thereby, there is no possibility that a human hand or the like is pinched by the stirring blades 44 in the processing container 42 in the dust discharge mode, and the operation of discharging the dry dust powder can be performed safely.

  In the garbage disposal apparatus 1, the garbage discharge mode is operated only while the user presses the discharge button of the operation unit 98. Accordingly, the user's hand is on the discharge button during the operation of the dust discharge mode, so that the user accidentally puts his hand into the discharge port 53 and is injured due to contact with the operating stirring blade 44 and crushing blade 62. Can be prevented.

  Further, in the garbage processing apparatus 1, the exhaust fan 97 rotates in a state where the front panel 41a is opened. Thus, during the dust discharge mode operation, the air in the processing container 42 is exhausted from the exhaust port 74 to the drain pipe 87 through the exhaust duct A85 and the like, and the air in the processing container 42 leaks to the room side through the discharge port 53. Can be prevented.

  In the reciprocating rotation operation of the rotary blade from the dust discharge position to the return position in step B9, for example, the rotation of the stirring blade 44 from the dust discharge position in the direction of the arrow in FIG. If the position detection sensor 51a does not detect the passage of the stirring blade 44, it is determined that the stirring blade 44 cannot be rotated due to clogging with foreign matters, and the rotation of the stirring blade 44 is stopped, and an alarm is issued with a buzzer or a lamp. .

  When notified by a buzzer, a lamp, or the like that the garbage discharging operation has been completed, the user removes the bag adapter 120 or the garbage storage tray 121 attached with the bag 101 from the garbage processing apparatus 1 (step B11).

  After removing the bag adapter 120 or the garbage storage tray 121 from the garbage processing apparatus 1, the user operates the handle 60 to close the cover unit 58 and fit the shaft 60a to the hook portion 57 to lock the cover unit 58. (Step B12). Here, when the shaft 60 a fits into the hook portion 57, the system controller 92 detects the lock of the cover unit 58 from the output of the discharge port opening / closing detection sensor.

  After closing the discharge port 53, the user closes the front panel 41a of the cover 41 (step B13). If it is detected from the output of the sensor 93 that the front panel 41a of the cover 41 is closed, and the system controller 92 detects 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 for the garbage throwing 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.

  After step B13 ends, the system controller 92 stops the exhaust fan 97 (step B14). Further, the user discards the dry waste powder stored in the bag 101 or the dust storage tray 121.

  Here, in the above-described discharge operation example, the operation is performed in the dust discharge mode only while the user presses the discharge button. However, after the user presses and releases the discharge button, the reciprocating operation of the stirring blade 44 from the dust discharge position to the return position may be performed a predetermined number of times.

  In the example of the discharging operation described above, the rotation of the stirring blade 44 from the dust discharge position to the return position may be performed at a faster speed than the rotation from the return position to the dust discharge position. As a result, the time required for the discharging operation can be shortened.

  Further, a return position sensor for detecting the position of the stirring blade 44 may be provided at a position corresponding to the return position, and the return position detection sensor may be used to control the reciprocating rotation of the stirring blade 44 in step B9 in FIG. Good.

  In the above-described operation example, when the stirring blade 44 is rotating when the front panel 41a is opened, the rotation of the stirring blade motor 67 is stopped when the origin position detection sensor 51a detects the stirring blade 44. Thus, the stirring blade 44 is stopped at the origin position. However, when the front panel 41a is opened with the stirring blade 44 rotating, if the stirring blade 44 is in a position other than the discharge port 53, the stirring blade 44 may be stopped on the spot. When the stirring blade 44 stops at a position other than the discharge port 53, when the dust discharge mode is executed and the stirring blade 44 operates, the user accidentally puts a hand into the discharge port 53 and makes contact with the stirring blade 44. Injury can be prevented.

  As described above, according to the garbage processing apparatus 1 according to the present invention, the dry dust powder is discharged from the processing container 42 without touching the dry dust powder, and the bag 101 or the dust set in the discharge port 53 is discharged. It can be stored in the storage tray 121. For this reason, it becomes possible to easily perform the operation of disposing of the processed dry waste powder.

  In the flowchart at the time of the discharging process shown in FIG. 61, it is assumed that the exhaust fan 97 rotates when the opening of the front panel 41a is detected. However, the exhaust fan 97 may rotate when the opening of the discharge port 53 is detected instead of the opening of the front panel 41. Even if the exhaust fan 97 rotates when the opening of the discharge port 53 is detected, the air in the processing container 42 is exhausted from the exhaust port 74 to the drain pipe 87 through the exhaust duct A85 and the like during the dust discharge mode operation. Thus, it is possible to prevent the air in the processing container 42 from leaking to the room side through the discharge port 53.

  Further, a sensor for detecting the attachment / detachment of the filter unit 75 described above may be provided separately, and the exhaust fan 97 may be rotated when the removal of the filter unit 75 from the apparatus main body is detected. Thereby, the air in the processing container 42 is exhausted from the exhaust port 74 to the drain pipe 87 through the exhaust duct A85 and the like, and the air in the processing container 42 is prevented from leaking from the attachment portion of the filter unit 75 to the room side. Can do.

<Installation of garbage disposal equipment>
FIG. 72 is a side view showing an installation example of the garbage processing apparatus. 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 exposes the insertion cylinder part 21 of the lower unit 6 from the upper surface.

  In order to install the garbage processing apparatus 1, first, as shown in FIG. 72, the apparatus main body including the lower unit 6 is attached to a predetermined position below the sink 2a. Next, the upper unit 5 is fitted into the opening of the sink 2a from above. At this time, as shown in FIG. 3, the insertion opening 9 of the upper unit 5 and the insertion cylinder portion 21 of the lower unit 6 are fitted by the connecting member 24. Here, in the connecting member 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 observed. is there. 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.

  In this example, since the difference in the vertical dimension under the sink 2a is absorbed by the connecting member 24, fine adjustment in the height direction of the apparatus main body is facilitated. Then, the upper unit 5 is fixed to the sink 2 a by screwing a fixing ring (not shown) 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.

  INDUSTRIAL APPLICABILITY The present invention is extremely suitable when applied to a dry-type garbage disposal apparatus that is incorporated under a sink in a kitchen or a dishwasher and pulverizes vegetable scraps, bread crumbs, chicken eggshells, and the like into dry granules.
