Description

  The present invention relates to a garbage dewatering system.

  Garbage generated in the kitchen contains a large amount of moisture, which increases the weight of household garbage and causes bad odor. In conventional kitchen systems, solid-liquid separation of garbage containing moisture such as raw garbage is performed. In a conventional kitchen system, a drainage container connected to a drainage pipe is provided at the bottom of the sink. A garbage basket for collecting garbage is detachably inserted into the drainage container. The garbage basket is formed with a plurality of holes for discharging the water in the garbage basket to the drainage container. The moisture of the garbage in the garbage basket is discharged as drainage into the drainage container through a plurality of holes. That is, solid-liquid separation of garbage is performed by a garbage basket that collects garbage. Here, if the solid-liquid separation of the garbage in the garbage basket is not sufficient, wet garbage will be discarded by hand, resulting in a great stress.

  Conventionally, as shown in Patent Documents 1 and 2, a technique has been proposed in which solid-liquid separation is promoted and debris is dehydrated by rotating a garbage basket and applying centrifugal force to the garbage in the garbage basket. Further, Patent Document 3 discloses a technique of a dredge dewatering device in which the rotation driving force of the draining basket is stopped or the rotation of the draining basket is stopped when the lid of the draining basket is removed or removed during operation. It is disclosed.

The branch pipe 7 is connected to the inlet 27 a of the nozzle 27.

  The lid 4 is fitted to the sink opening 22 to close the sink opening 22. The lid 4 has a cylindrical shape with the top closed. The lid 4 has a disk part 41 and a cylindrical part 42. The cylindrical portion 42 has a cylindrical shape. The disk part 41 has a disk shape and closes the upper end of the cylindrical part 42. A concave portion 43 is formed in the central portion of the disk portion 41 in the radial direction. A knob 44 that protrudes upward is formed at the center of the recess 43 in the radial direction. The knob 44 has a cylindrical shape, and the tip thereof is located above the upper surface of the disk portion 41. Thereby, even if the user is in a state where water is accumulated in the recess 43, the user can pick up the knob 44 and lift the lid 4 without touching the water.

  A plurality of through holes 45 and a plurality of support protrusions 46 are formed in the cylindrical portion 42. The through hole 45 is formed in a rectangular shape and penetrates the cylindrical portion 42 in the radial direction from the inner wall surface to the outer wall surface. The through holes 45 are continuously formed at predetermined intervals in the circumferential direction of the cylindrical portion 42. The support protrusion 46 is formed between the adjacent through holes 45 and 45. The support protrusion 46 is a columnar protrusion having a rectangular cross section, and protrudes outward in the radial direction with respect to the outer peripheral surface of the cylindrical portion 42. In the present embodiment, four support protrusions 46 are arranged at equal intervals in the circumferential direction. The lower end 46a of the support protrusion 46 and the lower end 45a of the through hole 45 are on the same plane.

  The garbage car 3 has a car body 3A and a ring member 3B. As shown in FIGS. 3 and 4, the car body 3A has a bottomed cylindrical shape. The garbage basket 3 is detachably stored in the drainage container 2. The garbage basket 3 has a car opening 32 that is an opening on the side opposite to the bottom 31. That is, the car opening 32 is formed on the sink opening 22 side in a state where the garbage car 3 is stored in the drainage container 2. In a state where the garbage basket 3 is stored in the drainage container 2, the tip of the garbage basket 3 on the sink opening 22 side is positioned between the upper flange portion 25 and the lower flange portion 24 of the drainage container 2 in the axial direction. doing. The car body 3 </ b> A has a bearing portion 33. The bearing portion 33 is formed on the bottom portion 31. The bearing portion 33 is a concave portion that is recessed upward with respect to the outer wall surface of the bottom portion 31. The bearing portion 33 is configured to rotatably support the garbage basket 3 by inserting the shaft end portion of the shaft member 23. The bearing portion 33 has a bottomed cylindrical shape, has an opening with respect to the outer wall surface of the bottom portion 31, and extends from the outer wall surface of the bottom portion 31 toward the car opening portion 32 side (sink opening portion 22 side). Is formed.

  A taper portion 23 a is formed on the shaft member 23 on the sink opening portion 22 side. The tapered portion 23a is formed in a tapered shape whose diameter decreases from the bottom side, which is the base end side, toward the sink opening 22 side, which is the distal end side. The tip of the tapered portion 23a is a curved surface that is convex toward the sink opening 22 side. That is, the shaft member 23 rotatably supports the bearing portion 33 by point contact at the shaft end portion on the sink opening portion 22 side which is the tip thereof. The tapered portion 23a may have a pointed shape with a sharp point.

  The length in the axial direction of the tapered portion 23 a is equal to or greater than the depth in the axial direction of the bearing portion 33. For this reason, only a part of the tip end side of the tapered portion 23 a is inserted into the bearing portion 33. In other words, the base end of the taper portion 23 a, that is, the bottom side end is located below the bearing portion 33. Thereby, the garbage basket 3 can rotate in a state where the bearing portion 33 is in contact with only the tip of the tapered portion 23a.

  The ring member 3B is attached to the end of the car body 3A on the sink opening 22 side. The ring member 3B has a ring shape, and the inner diameter thereof is the same as the inner diameter of the car body 3A. Further, the outer diameter of the ring member 3B is larger than the outer diameter of the car body 3A. That is, the ring member 3B projects outward in the radial direction with respect to the car body 3A. In a state where the garbage basket 3 is stored in the drainage container 2, the outer diameter of the garbage basket 3 is smaller than the corresponding inner diameter on the inner peripheral surface of the drainage container 2. That is, the garbage basket 3 can be held in a state in which a gap is maintained between the garbage basket 3 and the inner peripheral surface of the drainage container 2 while being stored in the drainage container 2. In other words, the garbage basket 3 can rotate without contacting the inner peripheral surface of the drainage container 2 in a state where the bearing portion 33 is supported by the shaft member 23. For example, when the central axis (rotation axis) X of the garbage basket 3 is on the central axis of the drainage container 2, the garbage basket 3 can rotate without contacting the inner peripheral surface of the drainage container 2.

  Further, the garbage basket 3 is in contact with the inner peripheral surface of the drainage container 2 by the rotation axis X being inclined with respect to the central axis of the drainage container 2. In the present embodiment, the fact that the rotation axis X of the garbage basket 3 is inclined with respect to the central axis of the drainage container 2 is simply described as “the garbage basket 3 is inclined with respect to the drainage container 2”. When the garbage basket 3 is inclined with respect to the drainage container 2, the outer peripheral surface of the ring member 3 </ b> B comes into contact with the inner peripheral surface of the drainage container 2. A flange portion 37 corresponding to the lower flange portion 24 of the drainage container 2 is formed on the outer peripheral side of the ring member 3B. The flange portion 37 is a protruding portion that protrudes radially outward in the ring member 3B. The flange portion 37 is located above the lower flange portion 24 of the drainage container 2 and faces the lower flange portion 24 in the axial direction.

  When the garbage basket 3 is inclined with respect to the drainage container 2, the flange portion 37 of the garbage basket 3 comes into contact with the lower flange portion 24 of the drainage container 2. That is, the ring member 3 </ b> B can function as a brake member that comes into contact with the inner peripheral surface of the drainage container 2 and stops the rotation of the garbage basket 3 when the rotation axis X of the garbage basket 3 is inclined.

  A plurality of engagement grooves 34 are formed in the ring member 3B. The engagement groove 34 is engaged with an engagement protrusion 52 of the rotating member 5 described later. The engagement groove 34 is formed on the upper surface of the ring member 3B. The engagement groove 34 is formed in a trapezoidal shape when viewed in the axial direction. The engagement groove 34 has a tapered shape in which the circumferential width increases from the outside in the radial direction toward the inside. The radially inner end of the engagement groove 34 is open toward the interior of the car body 3A. In other words, the engagement groove 34 extends outward in the radial direction from the inner peripheral surface of the ring member 3B. The engagement grooves 34 are formed continuously at a predetermined interval in the circumferential direction. For example, the engagement grooves 34 are arranged at equal intervals in the circumferential direction.

  A plurality of fins 35 are formed on the outer peripheral surface of the car body 3A. The fin 35 is formed in the central portion of the car body 3A in the axial direction. The fins 35 are continuously arranged at a predetermined interval in the circumferential direction. For example, the fins 35 are arranged at equal intervals in the circumferential direction. The fin 35 is a plate-like member having an L-shaped cross section when viewed in the axial direction. The fin 35 protrudes in a direction orthogonal to the outer peripheral surface of the car body 3A, that is, in the radial direction, and an end portion on the outer side in the radial direction is bent rearward in the rotational direction. The size of the fin 35 is set such that the tip of the fin 35 in the radial direction of the garbage basket 3 does not contact the inner wall surface of the drainage container 2 in a state where the garbage basket 3 is stored in the drainage container 2. The blade surface 35a of the fin 35 is parallel to the central axis (rotation axis) X of the car body 3A and is orthogonal to the rotation direction.

  A plurality of dewatering holes 36 are formed in the car body 3A. The dewatering hole 36 is for discharging the water in the garbage basket 3 to the drainage container 2. In the present embodiment, the plurality of dewatering holes 36 are formed so as to penetrate from the inner wall surface to the outer wall surface at the bottom 31 and the outer peripheral surface of the garbage basket 3.

  When the user places the garbage basket 3 in the drainage container 2, the shaft member 23 of the drainage container 2 is inserted into the bearing portion 33 of the garbage basket 3. The bottom side of the bearing portion 33 has a larger diameter than the sink opening 22 side. Thus, when the diameter of the opening of the bearing portion 33 is larger than the diameter of the inner portion, when the user stores the garbage basket 3 in the drainage container 2, the bearing portion 33 can be easily provided. On the other hand, the shaft member 23 can be inserted. When the garbage basket 3 is stored in the drainage container 2, the shaft member 23 comes into contact with the ceiling surface of the bearing portion 33, and the garbage basket 3 is rotatably supported by the shaft member 23.

  As shown in FIGS. 5 and 6, the rotating member 5 is rotatably supported by the lid 4. The rotating member 5 has a disk part 51, an engaging protrusion 52 and a bearing part 53. The disk part 51 has a disk shape and faces the back surface (lower surface) of the disk part 41 of the lid 4 in the axial direction. The bearing portion 53 is disposed in the center portion of the disk portion 51 in the radial direction. The bearing portion 53 is supported by the bolt 47 and rotatably supports the disc portion 51. The bolt 47 is inserted into the through hole of the bearing portion 53 from below and is screwed into the bolt hole 44 a of the knob 44. Thus, the rotating member 5 is supported by the lid 4 via the bolts 47 and can rotate relative to the lid 4. Further, the central axis of the rotating member 5 and the central axis of the lid 4 are on the same line.

  A plurality of through holes 54 are formed in the disk portion 51. The through hole 54 is formed so as to penetrate the disk portion 51 in the axial direction from the front surface to the back surface. The through hole 54 is formed in a fan shape and is continuously formed in the circumferential direction. For example, the through holes 54 are arranged at equal intervals in the circumferential direction.

  The engagement protrusion 52 is formed on the lower surface of the disk portion 51. The engagement protrusion 52 is disposed in the vicinity of the outer edge of the disk portion 51. The engagement protrusion 52 protrudes toward the side opposite to the lid 4 side with respect to the lower surface of the disk portion 51. The engaging protrusion 52 is formed in a shape corresponding to the engaging groove 34 of the garbage basket 3. The engaging protrusion 52 is formed in a tapered shape whose width in the circumferential direction increases from the outside in the radial direction toward the inside. The engaging protrusions 52 are continuously formed at a predetermined interval in the circumferential direction. For example, the engagement protrusions 52 are arranged at equal intervals in the circumferential direction. In the present embodiment, the four engagement protrusions 52 are arranged at equal intervals in the circumferential direction. Since the engaging groove 34 and the engaging protrusion 52 each have a tapered shape in which the width in the circumferential direction is increased from the outside in the radial direction toward the inside, the engaging protrusion 52 can be easily engaged with the engaging groove 34. Can be combined.

  Each engagement protrusion 52 can be engaged with the engagement groove 34 of the garbage basket 3 by the lid 4 fitting into the sink opening 22 of the drainage container 2. When the user holds the knob 44 of the lid 4 and fits the lid 4 into the sink opening 22 as indicated by the arrow Y1 in FIG. 2, the upper surface of the ring member 3B of the garbage basket 3 and the disk portion 51 of the rotating member 5 The lower surface of the is opposed. At this time, if the position of the engagement groove 34 and the position of the engagement protrusion 52 match, the engagement protrusion 52 engages with the engagement groove 34. Even if the position of the engagement groove 34 and the position of the engagement protrusion 52 are misaligned, the user can easily align the engagement protrusion 52 with respect to the engagement groove 34 by rotating the lid 4. Can be engaged. When the engaging protrusion 52 is engaged with the engaging groove 34, the relative rotation between the rotating member 5 and the garbage basket 3 is restricted. That is, the engaging protrusion 52 engages with the engaging groove 34, whereby the rotating member 5 engages with the garbage basket 3 so as to be integrally rotatable.

  When the engagement protrusion 52 is engaged with the engagement groove 34, the support protrusion 46 of the lid 4 comes into contact with the upper flange portion 25 of the drainage container 2. Thereby, the positioning of the lid 4 in the vertical direction is performed. In a state where the support protrusion 46 is in contact with the upper flange portion 25, the engagement protrusion 52 is engaged with the engagement groove 34 and is separated from the bottom of the engagement groove 34. That is, the engagement protrusion 52 can be engaged with the engagement groove 34 without pressing the garbage basket 3 downward.

  Further, the cylindrical portion 42 of the lid 4 is engaged with the sink opening 22 of the drainage container 2 so that the lid 4 is positioned in the radial direction. The outer diameter of the cylindrical portion 42 and the inner diameter of the sink opening 22 are corresponding sizes. For example, the inner diameter of the sink opening 22 is slightly larger than the outer diameter of the cylindrical portion 42. As a result, the cylindrical portion 42 is fitted into the sink opening 22, whereby the shaft member 23 of the drainage container 2 and the bolt 47 of the lid 4 are aligned. Therefore, the garbage basket 3 and the rotating member 5 are located on the same axis and can rotate together. In addition, by aligning the drainage container 2 and the lid 4, the garbage basket 3 is held by the rotating member 5 at a position spaced radially from the inner peripheral surface of the drainage container 2. That is, the garbage basket 3 can rotate while maintaining a gap in the radial direction with respect to the inner peripheral surface of the drainage container 2. The engaging protrusion 52 of the rotating member 5 engages with the engaging groove 34 of the garbage basket 3 so that the rotating member 5 can rotatably support the upper portion of the garbage basket 3. Therefore, the upper part of the garbage basket 3 is supported by the rotating member 5 and the lower part is supported by the shaft member 23, so that the rotating shaft can be rotated without shaking.

  The through hole 45 of the lid 4 is for discharging the water of the sink 102. With the support protrusion 46 of the lid 4 in contact with the upper flange portion 25 of the drainage container 2, the through-hole 45 of the lid 4 allows the sink 102 and the inside of the lid 4 to communicate with each other. Therefore, in a state where the lid 4 is fitted to the drainage container 2, the water in the sink 102 flows into the lid 4 through the through hole 45 and flows into the garbage basket 3 through the through hole 54 of the rotating member 5. can do. When the user uses the kitchen faucet 106 and the sink 102 for cooking or washing, water in the sink 102 flows into the garbage basket 3 through the through holes 45 and 54, and the garbage is collected by the garbage basket 3. The water that has flowed into the garbage basket 3 is discharged into the sewage through the plurality of dewatering holes 36.

  Thus, in the state where the lid 4 is fitted to the drainage container 2, the water in the sink 102 is always discharged. Therefore, it is possible to prevent water from remaining in the sink 102. That is, when the dehydration of the garbage in the garbage basket 3 is completed and the lid 4 is removed, the sink 102 can be kept in a state where no water is accumulated.

  The water ejected from the nozzle 27 of the drainage container 2 is directed to the blade surface 35a of the fin 35 as indicated by an arrow Y2 in FIG. The ejection of water from the nozzle 27 is started, for example, when a dehydration switch is turned on by the user. As shown in FIG. 1, the dust dewatering system 1 includes a lid sensor 9 that detects that the lid 4 is fitted in the drainage container 2. The lid sensor 9 detects the fitting of the lid 4 when the lid 4 is inserted into the sink opening 22 to a depth sufficient for the engagement protrusion 52 to fit into the engagement groove 34. The lid sensor 9 is connected to the control unit 6. The control unit 6 is a control unit having a computer. The control unit 6 has a function of controlling the dust dewatering system 1.

  An on-off valve 8 is connected to the control unit 6, and the on-off valve 8 is controlled by the control unit 6. The controller 6 opens the on-off valve 8 when it is detected by the lid sensor 9 that the lid 4 is fitted to the drainage container 2 and the dehydration switch is ON. When the on-off valve 8 is opened, high-pressure water is supplied from the pipe 104 to the nozzle 27 via the branch pipe 7, and water is ejected from the nozzle 27. The water ejected from the nozzle 27 hits the blade surfaces 35 a of the fins 35 of the garbage basket 3 and rotates the garbage basket 3. The fin 35 is capable of efficiently converting the received water pressure into a rotational force with respect to the garbage basket 3 by bending the radially outer end toward the rear in the rotational direction.

  When the garbage basket 3 rotates, a centrifugal force acts on the garbage in the garbage basket 3 while the garbage basket 3 is rotating. The garbage is pressed against the inner wall surface of the garbage basket 3 by centrifugal force, and the moisture of the garbage is discharged to the drainage container 2 through the plurality of dewatering holes 36 to dehydrate the garbage. When the dehydration switch is turned off by the user and when the lid sensor 9 no longer detects that the lid 4 is fitted to the drainage container 2, the control unit 6 closes the on-off valve 8. That is, the controller 6 automatically stops the ejection of water from the nozzle 27 when the lid 4 fitted to the sink opening 22 is detached from the sink opening 22 as indicated by the arrow Y3 in FIG.

  When the on-off valve 8 is closed and the branch pipe 7 is closed, the supply of water to the nozzle 27 is stopped, and the nozzle 27 stops ejecting water. As a result, the garbage basket 3 stops rotating. When the rotation axis X of the garbage basket 3 is inclined, as shown in FIG. 7, the flange portion 37 of the garbage basket 3 comes into contact with the lower flange portion 24 of the drainage container 2, and the rotation of the garbage basket 3 is braked. The rotation of 3 stops. The garbage G is pressed against the inner wall surface of the garbage basket 3 and dehydrated.

  After the dehydration of the garbage G in the garbage basket 3 is completed and the dehydration switch is turned off, the user removes the lid 4 from the sink opening 22, removes the garbage basket 3 from the drainage container 2, and removes the garbage in the garbage basket 3. The dewatered garbage G is discarded. The water hitting the blade surfaces 35 a of the plurality of fins 35 during dehydration travels along the outer peripheral surface of the garbage basket 3 or the inner peripheral surface of the drainage container 2 and is discharged into the sewage through the drainage pipe 105. Accordingly, when the garbage basket 3 and the drainage container 2 are exposed to water during the rotation of the garbage basket 3, the dirt basket 3 and the drainage container 2 can be cleaned. Thereby, cleaning of the drainage container 2 and the garbage basket 3 by a user can be simplified.

  Here, a predetermined time is required from the stop of the ejection of water by the nozzle 27 until the rotation of the garbage basket 3 stops. If the lid 4 is removed before the rotation of the garbage basket 3 stops, the garbage basket 3 that has been rotated will be exposed. If the rotating garbage basket 3 is exposed, it is not preferable because water splashes from the garbage basket 3 to the sink 102. Further, it is not preferable that the garbage basket 3 keeps rotating while the user can touch it. When the lid 4 is removed, it is preferable that the rotation of the garbage basket 3 is quickly stopped.

  The center of gravity of the garbage basket 3 of this embodiment is eccentric with respect to the rotation axis X of the garbage basket 3. As a result, when the lid 4 is removed, the flange portion 37 of the garbage basket 3 comes into contact with the lower flange portion 24 of the drainage container 2 and the rotation of the garbage basket 3 is braked, and the rotation of the garbage basket 3 is quickly stopped. Even if the center of gravity of the garbage basket 3 is eccentric with respect to the rotation axis X, the rotating member 5 remains in the garbage while the lid 4 is fitted to the sink opening 22 and the rotating member 5 is engaged with the garbage basket 3. By supporting the car 3, the rotation axis X of the garbage car 3 is suppressed from being inclined with respect to the central axis of the drainage container 2. On the other hand, when the lid 4 is removed from the sink opening 22 and the engagement between the rotating member 5 and the garbage basket 3 is released, the garbage basket 3 is not supported by the rotating member 5. Since the center of gravity of the garbage basket 3 is eccentric with respect to the rotational axis X, the rotational axis X of the garbage basket 3 is inclined with respect to the central axis of the drainage container 2, and the ring member 3B is placed on the inner peripheral surface of the drainage container 2. Contact. As a result, when the lid 4 is removed, the garbage basket 3 comes into contact with the inner peripheral surface of the drainage container 2 and stops rotating in a short time.

  Thus, according to the garbage dewatering system 1 of the present embodiment, even if the garbage basket 3 is rotating at the time when the lid 4 is removed, the garbage basket 3 is quickly stopped by removing the lid 4. To do. Even if water is ejected from the nozzle 27, the garbage basket 3 comes into contact with the inner peripheral surface of the drainage container 2 and stops rotating. Therefore, it is suppressed that the garbage basket 3 exposed when the lid 4 is removed continues to rotate. The bearing portion 33 of the garbage basket 3 is supported by a tapered portion of the shaft member 23. In other words, the shaft member 23 supports the garbage basket 3 in the axial direction, but does not support the garbage basket 3 with respect to a force for tilting the rotation axis X. That is, the shaft member 23 allows the rotation axis X of the garbage basket 3 to be inclined with respect to the vertical axis while supporting the bearing portion 33.

  Therefore, when the lid 4 is removed from the drainage container 2 and is no longer supported by the rotating member 5, the rotation axis X of the garbage basket 3 is easily inclined, and the garbage basket 3 comes into contact with the inner peripheral surface of the drainage container 2. Stop rotating immediately. Further, since the center of gravity of the garbage basket 3 is eccentric with respect to the rotation axis X, the inclination of the garbage basket 3 is promoted, and the garbage basket 3 is easily brought into contact with the inner peripheral surface of the drainage container 2. Therefore, according to the garbage dewatering system 1 of the present embodiment, it is possible to suppress the garbage basket 3 from continuing to rotate with a simple configuration without requiring a complicated mechanism.

  Further, when dewatering the garbage G, the rotating member 5 supports the ring member 3B of the garbage basket 3 so that the rotation of the rotational axis X of the garbage basket 3 is suppressed. Therefore, the difference in diameter between the ring member 3B and the ring member 3B in the drainage container 2 and the corresponding inner wall surface can be made small. Thus, even if the difference in diameter is slight, the garbage basket 3 can rotate while the ring member 3B does not contact the inner wall surface while being supported by the rotating member 5. On the other hand, when the lid 4 is removed from the drainage container 2, the rotation axis X of the garbage basket 3 is shaken, and the ring member 3 </ b> B approaches the inner wall surface of the drainage container 2. If the difference in diameter between the ring member 3B and the inner wall surface of the drainage container 2 is made small, the lid 4 is removed from the drainage container 2 and the rotation axis X is slightly inclined, so that the garbage basket 3 is drained. Stops in contact with the inner wall surface of 2.

  As a means for decentering the center of gravity of the garbage basket 3 with respect to the rotation axis X, for example, the garbage basket 3 may be molded in advance so that the center of gravity is eccentric with respect to the rotation axis X, and the garbage basket 3 is weighted after molding. You may make it attach. The center of gravity of the car body 3A may be eccentric with respect to the rotation axis X, or the center of gravity of the ring member 3B may be eccentric with respect to the rotation axis X.

  The rotation of the garbage basket 3 and the rotating member 5 is performed by engaging the garbage basket 3 and the rotating member 5 so that the center of gravity of the rotating member 5 is eccentric with respect to the rotation axis of the rotating member 5. The center of gravity of the body may coincide with the rotation axis X. Alternatively, when the garbage basket 3 and the rotating member 5 are engaged, the center of gravity of the rotating body including the garbage basket 3 and the rotating member 5 is more eccentric with respect to the rotation axis X than the center of gravity of the garbage basket 3 alone. The degree may be reduced. By doing in this way, it is possible to make the rotation of the garbage basket 3 smoother when the garbage G is dehydrated.

  In the garbage dewatering system 1 of this embodiment, even if the center of gravity of the garbage basket 3 is not decentered with respect to the rotation axis X, the rotation of the garbage basket 3 is quickly stopped when the lid 4 is removed. In the garbage basket 3, the distribution of the garbage G is biased, so that the center of gravity of the garbage basket 3 including the garbage G is eccentric with respect to the rotation axis X. As shown in FIG. 7, the garbage G is pressed against the inner wall surface of the garbage basket 3 by the rotation of the garbage basket 3, and at this time, the distribution of the garbage G is biased. Thus, the center of gravity of the garbage basket 3 including the garbage G is decentered with respect to the rotational axis X, so that when the lid 4 is removed, the rotational axis X is inclined with respect to the central axis of the drainage container 2 and the garbage basket 3 is drained. 2 in contact with the inner peripheral surface. Therefore, even if the center of gravity of the garbage basket 3 is on the rotation axis X, when the lid 4 is removed after the garbage G is dehydrated, the rotation of the garbage basket 3 is quickly stopped.

  In addition, the structure of the bearing part 33 and the shaft member 23 is not limited to what was illustrated. For example, the bearing portion 33 of the present embodiment is formed as a separate member that can be attached to and detached from the car body 3A, but is not limited thereto. The bearing portion 33 may be one in which the central portion of the bottom of the car body 3A is recessed toward the sink opening 22 side. Moreover, the shape of the shaft member 23 should just be what supports the bearing part 33 to an axial direction by point contact. In the garbage dewatering system 1 according to the present embodiment, the amount of the bearing portion 33 of the garbage basket 3 protruding into the garbage basket 3 can be made small so that the capacity of the garbage basket 3 can be sufficiently secured.

(Modification of the first embodiment)
A modification of the first embodiment will be described. In the present modification, the difference from the first embodiment is that when the lid 4 is removed, the shaft member 23 is pushed out of the bearing portion by the spring mechanism. FIG. 8 is a view showing a bearing portion according to this modification when the lid 4 is removed from the drainage container 2, and FIG. 9 is a diagram showing this modification when the lid 4 is fitted to the drainage container 2. It is a figure which shows this bearing part.

  The bearing part 133 has a cylindrical part 133a, a spring 133b, and a disk part 133c. The cylindrical portion 133a has a bottomed cylindrical shape, has an opening with respect to the outer wall surface of the bottom portion 31, and extends from the outer wall surface of the bottom portion 31 toward the sink opening portion 22 side. The disk part 133c has a disk shape, and the outer diameter of the disk part 133c is determined corresponding to the inner diameter of the cylindrical part 133a. The disk part 133c is arrange | positioned in the cylindrical part 133a, and the disk part 133c and the cylindrical part 133a are connected via the spring 133b. The spring 133b biases the disk portion 133c toward the bottom side.

  When the lid 4 is removed from the drainage container 2, as shown in FIG. 8, the garbage basket 3 is pushed upward by the urging force of the spring 133b, and the shaft member 23 is pushed out from the cylindrical portion 133a of the bearing portion 133. . When the user fits the lid 4 into the drainage container 2, the rotating member 5 is engaged with the garbage basket 3, and the garbage basket 3 is moved to the bottom side by the pressing force with which the lid 4 and the rotating member 5 are engaged. Pressed. As a result, as shown in FIG. 9, the garbage basket 3 is pushed down against the biasing force of the spring 133 b, and the shaft member 23 is inserted into the cylindrical portion 133 a of the bearing portion 133.

  Therefore, in the refuse dewatering system 1 having the bearing portion 133 of this modification, when the lid 4 is fitted in the sink opening 22 of the drainage container 2, the shaft member 23 is inserted into the bearing portion 133 and the disk portion. The garbage basket 3 is rotatably supported via 133c. Here, the insertion depth of the shaft member 23 and the diameter of the shaft member 23 are set so that the outer peripheral surface of the shaft member 23 supports the inner peripheral surface of the cylindrical portion 133a in a state where the shaft member 23 is inserted into the bearing portion 133. May be. If it does in this way, stability of rotation of garbage basket 3 at the time of dehydration can be raised. On the other hand, when the lid 4 is removed from the drainage container 2, the garbage basket 3 is lifted by the urging force of the spring 133 b, and the shaft member 23 is pushed out from the bearing portion 133. As a result, the rotation axis X of the garbage basket 3 is inclined more easily than the state in which the shaft member 23 is inserted into the bearing portion 133, and the garbage basket 3 comes into contact with the inner peripheral surface of the drainage container 2 to rotate the garbage basket 3. Stops.

  In addition, when the lid | cover 4 is removed from the drainage container 2, you may make it the disc part 133c incline. FIG. 10 is a diagram illustrating a state in which the disk portion 133c is inclined. When the shaft member 23 is inserted into the cylindrical portion 133a, the disc portion 133c is orthogonal to the rotation axis X as shown in FIG. 9, and when the shaft member 23 is pushed out, the disc is shown in FIG. The central axis of the portion 133 c is inclined with respect to the rotational axis X of the garbage basket 3. In this way, when the lid 4 is removed from the drainage container 2, the rotation axis X is quickly inclined, and the garbage basket 3 is brought into contact with the inner peripheral surface of the drainage container 2 to stop the rotation of the garbage basket 3. Can be made. As a means for inclining the disk portion 133c, for example, a protrusion can be provided on the inner peripheral surface of the cylindrical portion 133a. When the lid 4 is removed from the drainage container 2 and the disk portion 133c moves toward the bottom side, the disk portion 133c can be tilted by the engagement of the disk portion 133c with the protrusion.

  In addition, when the lid 4 is removed from the drainage container 2, the center axis of the bearing portion 133 is inclined with respect to the center axis of the shaft member 23, or the center axis of the bearing portion 133 with respect to the center axis of the shaft member 23. A configuration for decentering may be used.

(Second Embodiment)
A second embodiment will be described. In the second embodiment, components having the same functions as those described in the first embodiment are given the same reference numerals, and duplicate descriptions are omitted. This embodiment is different from the first embodiment in that the rotation axis X of the garbage basket 3 is positively inclined by the water ejected from the nozzle 27 and hitting the blade surface 35a of the fin 35.

  As shown in FIG. 2, the number of nozzles 27 provided in the drainage container 2 is one. Moreover, the water ejection direction by the nozzle 27 is a direction orthogonal to the blade surface 35a. For this reason, the garbage basket 3 receives a force for inclining the rotation axis X together with a force for rotating the garbage basket 3 due to water ejected from the nozzle 27 and hitting the blade surface 35 a of the fin 35. Here, the force for inclining the rotation axis X is a force acting on the garbage basket 3 in a direction perpendicular to the rotation axis X. While water is ejected from the nozzle 27, the garbage basket 3 continues to receive a force for inclining the rotation axis X. In a state where the lid 4 is detached from the sink opening 22, the water hitting the blade surface 35 a generates a force for inclining the rotation axis X with respect to the garbage basket 3, and the garbage basket 3 is inclined with respect to the drainage container 2. In addition, the jet direction of the water by the nozzle 27 is not limited to the direction orthogonal to the blade surface 35a. The water jetting direction may be a direction in which the water hitting the blade surface 35 a generates a force for inclining the rotation axis X with respect to the garbage basket 3.

  When the lid 4 is removed, the lid sensor 9 no longer detects that the lid 4 is fitted to the drainage container 2, and the water that is ejected from the nozzle 27 by the lid valve 9 is closed. The garbage basket 3 receives a force for inclining the rotation axis X until it stops hitting, and the rotation axis X is inclined. Therefore, when the lid 4 is removed, the garbage basket 3 can be inclined with respect to the drainage container 2 by the force of water ejected from the nozzle 27. Therefore, the garbage basket 3 can be brought into contact with the inner peripheral surface of the drainage container 2 in a short time after the lid 4 is removed.

  Further, in the present embodiment, a predetermined delay time is provided from when the lid 4 is removed by the user and the lid 4 is detached from the sink opening 22 until the ejection of water by the nozzle 27 is stopped. Thereby, even after the lid 4 is removed, the ejection of water is not stopped until the delay time elapses, and the force for inclining the rotation axis X continues to act on the garbage basket 3. Therefore, the garbage basket 3 can be quickly brought into contact with the inner peripheral surface of the drainage container 2 to stop the rotation of the garbage basket 3.

  The controller 6 keeps the on-off valve 8 open until a predetermined delay time elapses after the lid sensor 9 no longer detects that the lid 4 is fitted to the drainage container 2. To do. This delay time is determined based on, for example, the time required for bringing the garbage basket 3 into contact with the inner peripheral surface of the drainage container 2. When the delay time elapses, the control unit 6 closes the on-off valve 8.

  In the present embodiment, the number of nozzles 27 provided in the drainage container 2 is one, but is not limited thereto. There may be a plurality of nozzles 27. The plurality of nozzles 27 may be arranged so that the resultant force of each nozzle 27 acting on the fin 35 has a component force that causes the rotation axis X to be inclined. Further, when a plurality of nozzles 27 are arranged in the drainage container 2, when water is ejected from all the nozzles 27, the force for inclining the rotation axis X to the garbage basket 3 does not act, and the predetermined nozzle 27 When the jet of water is stopped, a force for inclining the rotation axis X may be applied to the garbage basket 3. When the nozzles 27 are arranged in this way, water is ejected to all the nozzles 27 when the lid 4 is fitted to the drainage container 2, and water is ejected from the predetermined nozzle 27 when the lid 4 is removed. If stopped, the garbage basket 3 can be brought into contact with the inner peripheral surface of the drainage container 2 by the force of water.

  The center of gravity of the garbage basket 3 is decentered with respect to the rotation axis X as in the first embodiment, and the garbage basket is driven by the force of water ejected from the nozzle 27 when the lid 4 is removed as in the present embodiment. 3 rotation axis X may be inclined.

  The contents disclosed in the above embodiments can be executed in appropriate combination.

  As described above, the garbage dewatering system according to the present invention is suitable for suppressing the rotation of the garbage basket when the garbage basket is exposed, for example, when the lid of the drainage container is removed.
