Description

  The present invention relates to a disposer device applicable to a hammer mill type, a chain mill type, or the like. Specifically, the inside of the hopper and the crushing unit can be efficiently cleaned by detachably configuring a rotating disk or the like constituting the crushing unit.

  As a disposer device (garbage disposal device) for crushing garbage used in general households and restaurants, a hammer mill type, a chain mill type, and the like are known. A hammer mill type disposer device as disclosed in Patent Document 1 or Patent Document 2 is a fixed hammer or a swingable hammer on a rotating disk (hereinafter referred to as a turntable) disposed at the bottom of a cylindrical hopper. Is provided. A vertical rib-shaped annular fixed blade (comb blade-shaped fixed blade) is attached and fixed to the inner peripheral wall of the hopper so as to face the hammer.

  Patent Document 3 discloses a chain mill type disposer device in which a hammer is connected to a rotating disk by a chain instead of a hammer.

  Since the garbage thrown into the hopper is pressed against the inner peripheral surface of the hopper by centrifugal force generated by the rotation of the turntable, the garbage is crushed by the action of the hammer and the fixed blade. The crushed garbage falls downward from between the fixed blade and the fixed blade. The shredded garbage that has fallen is discharged to the drain pipe side.

  Such a disposer device operates a turntable or a rotating disk equipped with a hammer at a high speed of several thousand revolutions (rpm) in order to pulverize the garbage in the hopper. The inlet on the kitchen sink side of the hopper was narrowed.

  Thus, when the inner diameter of the charging port is narrow, cleaning in the hopper is troublesome. This is because if the inside of the hopper is not cleaned, the crushed material remaining in the hopper may be spoiled to cause a bad odor. Therefore, it is preferable that the structure be as easy to clean as possible.

  From this point of view, there has been proposed a disposer device in which the input port is enlarged and the crushing unit in the hopper can be attached and detached (for example, Patent Document 4).

  This disposer device is a hammer mill type, and is configured such that the crushing unit is mounted and fixed in a cylindrical housing and the housing is detachable from the hopper.

  In the detachable disposer device disclosed in Patent Document 4, since the housing itself can be detached from the hopper, it is easy to clean the inner and outer surfaces of the housing. However, since the crushing unit itself is mounted and fixed to the bottom of the housing, it is not possible to clean the crushing unit itself or remove the crushing unit and clean the bottom surface of the housing. Therefore, if crushed material remains on the bottom surface of the housing, it may be difficult to always keep the housing including the crushing unit clean.

  Although the crushing unit itself can be removed, in that case, since the crushing unit is removed from the housing using a tool, the operation is troublesome. Moreover, since the number of parts increases by providing a housing, there is a dislike of incurring a cost increase.

  Therefore, the present invention solves such a conventional problem, and proposes a disposer device that can be applied to a hammer mill type or a chain mill type in which the crushing unit itself can be removed and cleaned while omitting the housing. To do.

In order to achieve the above-mentioned problem, the disposer device according to claim 1 crushes the object to be crushed from the drain opening formed in the sink, and discharges the crushed object to the drain outlet side. Disposer device that
A crushing unit composed of a turntable and a hammer mechanism provided on the turntable;
A drive shaft that is mounted so as to penetrate substantially the center of the rotating disk, and that rotates the rotating disk;
A shaft support means, which is detachably attached to the tip of the drive shaft, and supports the rotary disk to the drive shaft;
It comprises a hopper in which the crushing unit is stored.

  The disposer apparatus according to the present invention includes a cylindrical hopper and a crushing unit disposed in the hopper. The crushing unit has at least a hammer mechanism. The crushing unit can take various configurations.

  The first type of crushing unit is a type in which a crushing unit is constituted by a small-diameter rotating disk connected to a drive shaft and a chain mill type hammer mechanism connected to the rotating disk. The second type of crushing unit is a type in which a crushing unit is configured by adding an annular crushing blade to the first type. The third type is a type in which a crushing unit is configured by a turntable having an outer diameter slightly smaller than the inner diameter of the hopper, a hammer mechanism, and a crushing blade. In the third type crushing unit, the hammer mechanism is composed of only a hammer that is swingably attached to the upper surface of the rotating disk.

  The configuration of the third type crushing unit will be described. This crushing unit has a turntable which is a rotating disk, and has a plurality of hammers near the outer peripheral edge of the upper surface of the turntable. ) Is attached. An annular comb-like crushing blade is attached to the inner peripheral wall of the hopper facing the swing hammer.

  A drive motor for driving the turntable is disposed on the bottom side of the hopper. The drive shaft of the drive motor passes through the shaft hole of the turntable and projects into the hopper by a predetermined length. The turntable is fixed to the drive shaft through a shaft support means.

  Since the garbage thrown into the hopper is pressed against the inner peripheral surface of the hopper by centrifugal force generated by the rotation of the turntable, the garbage is crushed by the action of the hammer and the crushing blade. The crushed garbage falls downward from between the crushing blade and the crushing blade. The shredded garbage that has fallen is discharged to the drain pipe side.

  A shaft support means for fixing the turntable to the drive shaft is provided at the tip of the drive shaft. The shaft support means is configured to be detachable from the drive shaft, and normally the turntable is fixed to the drive shaft. Since the engagement with the drive shaft is released by loosening the shaft support means, the turntable can be removed from the drive shaft.

  Since the bottom surface of the turntable is the bottom of the hopper, when the turntable is removed from the drive shaft, the inside of the hopper becomes hollow, and the inside of the hopper including the bottom can be cleaned to every corner. The crushing blade can also be cleaned. By removing the turntable, you can clean both the top and bottom surfaces of the turntable, so you can remove all the residue from the crushed material.

  The turntable that has been cleaned is inserted again into the drive shaft, and the turntable can be fixed to the drive shaft by fitting the shaft support means to the drive shaft in this state, so that a normal crushing process can be performed. During the crushing process, the upper surface of the hopper is closed.

  The shaft support means may have various configurations. The simplest is a configuration in which an engaging ball, which is provided on the shaft support body and is movable back and forth in the radial direction, is engaged with an annular groove of the drive shaft to lock the turntable to the drive shaft. This allows the crushing unit to be removed from the hopper with one touch. The same applies to the disposer apparatus using the first and second type hammer mechanisms.

  In this invention, the crushing unit comprised of a rotating disk and a hammer mechanism is configured to be detachable from the hopper.

  According to this, since the crushing unit can be easily detached from the hopper by releasing the shaft support state of the shaft supporting means with respect to the crushing unit, the hopper and the crushing unit can be easily cleaned.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In this invention, the crushing unit is detachably attached to the hopper. Various configurations of the crushing unit are conceivable. At least the following three types of crushing units can be applied.

  The first and second types of crushing units are crushing units used in so-called chain mill type disposer devices, and the third type is a crushing unit applicable to hammer mill type disposer devices.

Accordingly, the first type crushing unit is composed of a small-diameter rotating disk connected to the drive shaft and a chain mill type hammer mechanism connected to the rotating disk.
The crushing unit of the second type is a type in which a crushing unit is configured by adding an annular crushing blade to the first type. In both the first and second type crushing units, a fixed disk having a large diameter is attached to the lower side of the rotating disk, and the hammer mechanism is mounted on the fixed disk so as to be rotatable and swingable. The

  The third type is a hammer mill type in which a crushing unit is constituted by a rotating disk (turn table) having an outer diameter slightly smaller than the inner diameter of the hopper, a hammer mechanism and a crushing blade. In the third type crushing unit, the hammer mechanism is composed of only a hammer that is swingably attached to the upper surface of the rotating disk. Example 1 demonstrates the case where a 3rd type crushing unit is used.

FIG. 1 shows an example of a hammer mill type disposer device according to the present invention.
The disposer device 10 is attached and fixed so as to block the drainage port 12a from below the drainage port 12a of the sink (kitchen sink) 12.

  The disposer device 10 has a hopper 20. The hopper 20 has a cylindrical shape, and is a bottomed cylindrical body having an upper surface opened and a bottom surface closed. The bottom portion 22 of the hopper 20 is inclined toward the discharge port 24 side as shown in the figure, and crushed materials, washing water, etc. flowing down to the bottom portion 22 flow down the bottom portion 22 and pass through the discharge port 24 to the drain pipe side ( (Not shown).

  A drive motor 40 for driving a crushing unit to be described later is disposed on the bottom 22 side of the hopper 20. The drive motor 40 is fixed while being supported by the hopper support member 28.

  A drive shaft (rotary shaft) 42 of the drive motor 40 is attached so as to pass through the bottom portion 22 and be inside the hopper 20 and in the vicinity of the bottom portion 22. The drive shaft 42 has a small diameter portion 42 a on the tip end side, and the crushing unit 50 is attached to the stepped portion 43.

  A crushing unit 50 is mounted in the hopper 20. The crushing unit 50 is provided with a turntable 52 which is a rotating disk (rotating disk) and a hammer mechanism so as to face the outer peripheral edge 52 a of the upper surface of the turntable 52. Since it is a hammer mill type, the hammer mechanism is constituted only by the hammer 54. The hammer 54 is swingably attached. That is, a swing hammer configuration. The turntable 52 is placed so that the hub 53 abuts on a stepped portion 43 provided on the drive shaft 42.

  In the turntable 52, the shaft hole 53a is a square hole (for example, a square hole) so that the rotational driving force is transmitted from the drive shaft. The drive shaft 42 penetrating the shaft hole 53a is also formed as the same prismatic body.

  The turntable 52 differs depending on the size of the hopper 20, but has a diameter of about 15 cm and is formed of a metal plate (steel plate) having a thickness of about 3 to 5 mm. The size of the turntable 52 is smaller than the inner diameter of the drain port 12a of the kitchen sink 12 so that the turntable 52 can be removed from the kitchen sink 12.

  In the example of FIG. 1, as shown in FIG. 2, a pair of swing hammers 54a and 54b are pivotally mounted (rotatable) about the fulcrums 56a and 56b at a position of approximately 180 °. In the case of FIG. 1, the swing hammer 54 is attached so that the tip portion thereof is flush with the outer peripheral edge 52 a of the turntable 52.

  An annular crushing blade 58 is attached to the inner peripheral wall 21 of the hopper 20 that faces the swing hammer 54. The crushing blade 58 is a comb tooth having a vertical rib shape. The pitch of the comb teeth is arbitrary, but a pitch that can be crushed as finely as possible is used. In the case of FIG. 1, the height is the sum of the thickness of the turntable 52 and the thickness of the swing hammer 54, but this is an example. The height may be at least slightly higher than the thickness of the swing hammer 54.

  In the example shown in FIG. 1, the outer diameter of the crushing blade 58 is made substantially equal to the inner diameter of the hopper 20 in order to make it easy to determine the mounting position of the crushing blade 58 and to stably fix the crushing blade 58. . An annular step portion 30 is provided at a predetermined position on the inner peripheral wall 21 of the hopper 20, and is mounted and fixed in a state where the lower end surface of the crushing blade 58 is in contact with the step portion 30. The crushing blade 58 is fixed to the inner peripheral wall 21 of the hopper 20 using an adhesive or a screw.

  When the turntable 52 is mounted on the drive shaft 42, the tip end portion (small diameter portion) 42a of the drive shaft 42 protrudes from the upper surface of the hub of the turntable 52 by a predetermined length, and the turntable 52 is driven using this protrusion. It fixes to the axis | shaft 42. A shaft support means 60 is used for the fixing. Details of the shaft support means 60 are shown in FIGS.

  In order to fix the turntable 52 to the drive shaft 42, an annular groove 62 is formed at a predetermined position of the small diameter portion 42 a protruding from the hub 53 of the drive shaft 42. The annular groove 62 is a groove for engagement with an engagement ball 63, which will be described later. Therefore, the annular groove 62 is a semicircular annular recess.

  On the other hand, the shaft support body 64 fitted to the small diameter portion 42a has a fitting recess 65 having a predetermined depth therein. The fitting recess 65 has an inner diameter slightly larger than that of the small diameter portion 42a. A lock ring 66 is attached to the outer periphery of the shaft support body 64. A biasing spring 70 wound in a ring shape is attached to the annular recess 64a formed on the outer peripheral surface of the shaft support body 64, and one end side thereof is supported by the annular recess 64a.

  The other end side of the biasing spring 70 is supported by the inner surface of the annular protrusion 68 formed on the inner surface of the lock ring 66. In other words, the chord-wound urging spring 70 is mounted in the annular space 69 created by the annular recess 64a and the annular protrusion 68, whereby the lock ring 66 is always locked (direction of the drive motor 40). Be energized by. A plurality of through holes are formed radially in the shaft support body 64 facing the annular groove 62, and the engagement balls 63 are inserted into the through holes. A steel ball or a resin ball is used as the engagement ball 63.

  Even if the urging force of the urging spring 70 is applied to the lock ring 66, an annular stopper (O-ring) 72 is attached to the outer surface of the distal end of the shaft support body 64 and on the inner surface of the lock ring 66. The lock ring 66 is prevented from coming off the shaft support main body 64.

  Now, a procedure for pivotally supporting (fixing) the turntable 52 to the rotating shaft 42 using the pivotal support means 60 configured as described above will be described. FIG. 1 shows the shaft support state, and FIG. 3 shows the release state.

  When the shaft support main body 64 is mounted on the small diameter portion 42 a with the lock ring 66 pulled up, the engagement ball 63 is in a free state, and therefore the engagement ball 63 is in a position facing the annular groove 62. When inserted, the engagement ball 63 can be dropped into the annular groove 62.

  When the hand is released from the lock ring 66 in this state, the lock ring 66 is pushed back by the action of the biasing spring 70. At that time, the engagement ball 63 is urged in the direction of the annular groove 62 by the annular protrusion 68, thereby being pushed into the annular groove 62. Here, a state in which the lower end surface of the lock ring 66 (which is also the lower end surface of the shaft support main body 64) is in contact with the hub 53 is the terminal end movement position of the lock ring 66.

  The reason why the lower end surface of the lock ring 66 is brought into contact with the upper surface of the hub 53 in this way is to eliminate backlash when the turntable 52 is attached and to prevent vibration during the crushing process.

  When the lock ring 66 moves to the end, the engagement ball 63 is pushed toward the annular groove 62 by the annular convex portion 68, whereby the shaft support body 64 is locked to the drive shaft 42. That is, the turntable 52 is locked to the drive shaft 42 by the shaft support means 60.

  It is also possible to provide latch means (for example, a latch lever) for the lock ring 66 to latch the locked state.

  The crushing process is performed with the turntable 52 locked. When the crushing process is performed, the opening of the hopper 20 is closed by a lid 80 as shown in FIG. In this example, the crushing process starts when it is detected that the lid 80 is closed by the lid 80 and the lid 80 is locked to the hopper 20 in order to ensure safety during the crushing process.

  When the crushing process is completed and the internal crushing unit 50 is desired to be removed from the hopper 20, the engagement of the shaft support means 60 may be released. To release the lock, the lock ring 66 is pulled up as shown in FIG. Then, the pressure on the engagement ball 63 by the annular convex portion 68 is released, and the shaft support means 60 can be separated from the drive shaft 42 by pulling up the shaft support body 64 using the handle 67. By separating the shaft support means 60 from the drive shaft 42, the crushing unit 50, that is, the turntable 52 can be detached from the drive shaft 42 and the hopper 20 with one touch.

  When the turntable 52 is removed from the drive shaft 42, the inside of the hopper 20 becomes hollow, and the inside of the hopper including the bottom portion 22 can be cleaned to every corner. The cleaning becomes easy. The crushing blade 58 can also be cleaned. By removing the turntable 52, the upper and lower surfaces of the turntable 52 can be cleaned, so that all the residue of the crushed material can be removed. Since the opening of the hopper 20 is large, cleaning becomes easier. Since no housing is required, an effect of reducing the number of parts can be expected.

  In the first embodiment described above, the hammer 54 provided on the turntable 52 is a swing hammer that can swing freely, but the hammer 54 may be fixed to the turntable 52 and used.

  In the first embodiment, the drive shaft 42 of the drive motor 40 directly drives the turntable 52. However, a gear mechanism or a speed reduction mechanism including a pulley and a belt member is rotated between the drive shaft 42 and the turntable 52. An output shaft from the rotating mechanism can be used as a drive shaft.

  Instead of the engagement ball 63 described above, a ring member having a substantially C shape may be used. In this case, if the basic shape of the substantially C-shaped ring member is provided in substantially the same shape as the annular groove 62, the engagement between the annular groove 62 and the substantially C-shaped ring member is substantially the same as that of the C-shaped ring member itself. This is done by bullet deformation. At that time, the lock ring 66 allows the elastic deformation of the substantially C-shaped ring member by pulling up the lock ring 66, and when the lock ring 66 is moved to the end, the elastic ring of the substantially C-shaped ring member is allowed. It works to prevent the deformation. Of course, in a state where the lock ring 66 is moved to the end, the C-shaped ring member may be urged by the lock ring 66 and pushed into the annular groove 62.

  FIG. 4 shows another example of the shaft support means 60. In the case of FIG. 1, the turntable 52 is locked to the drive shaft 42 by cooperation of an annular groove (hereinafter referred to as an engagement groove) 62 and an engagement ball 63. The axial support means 60 of Example 2 shown in FIG. 4 is comprised as follows.

  As shown in FIG. 4, the shaft support means 60 also has a lock ring 66 that is mounted on the outer peripheral surface of the shaft support body 64 so as to be able to advance and retract. An engaging portion 90 is provided on the inner surface of the lock ring 66. The engaging portion 90 is a cylindrical body whose tip side (hub 53 side) is divided into two, and the rib 93 of the engaging portion 90 is loosely engaged with the support portion 92 of the shaft support body 64. ing.

  The front end portion of the engaging portion 90 opens in a trumpet shape, and the inner peripheral surface of the lock ring 66 is also inclined along the outer peripheral surfaces (inclined surfaces) 91a and 91b of the trumpet-shaped openings 90a and 90b. 67. The contact surface 67 functions as a pressing surface for the engaging portion 90 when locked.

  Engaging claws 94a and 94b having a wedge shape in this example are integrally formed on the outer peripheral surfaces 91a and 91b of the trumpet-shaped openings 90a and 90b. An engagement groove 62 is provided in the small-diameter portion 42a facing the engagement claws 94a and 94b. Therefore, the shape of the engagement groove 62 is a wedge-shaped annular recess corresponding to the engagement claws 94a and 94b.

  A biasing spring 70 is mounted in a space 69 formed between the outer peripheral surface of the engaging portion 90 and the inner surface of the lock ring 66, and biases the lock ring 66 in the locking direction.

  Now, in the shaft support means 60 configured as described above, FIG. 4 shows a locked state, and FIG. 5 shows an opened state thereof.

  Since the lock ring 66 is always urged downward by the action of the urging spring 70, the contact surface of the lock ring 66 as shown in FIG. Since the outer peripheral surfaces 91 a and 91 b are pressed by 67, the engaging claws 94 a and 94 b are fitted in the engaging grooves 62, and the locked state, that is, the turntable 52 is locked to the drive shaft 42.

  As shown in FIG. 5, when the lock ring 66 is pulled up against the biasing spring 70, the pressure on the engagement portion 90 by the lock ring 66 is released, so that the tip of the engagement portion 90 has a trumpet shape. Open. As a result, the engagement between the engagement claws 94a and 94b and the engagement groove 62 is released, and the shaft support means 60 can be removed from the drive shaft 42.

  It is also possible to provide latch means (for example, a latch lever) for the lock ring 66 to latch the locked state.

  In the first and second embodiments, the present invention is applied to the hammer mill type disposer apparatus 10, but the present invention can also be applied to a chain mill type disposer apparatus. The third embodiment shows a chain mill type disposer device 100 using a second type hammer mechanism. FIG. 6 is a sectional view of an essential part thereof, and FIG. 7 is a plan view thereof.

  The hammer mechanism 120 shown has a fixed disk 110 that supports the hammer mechanism body. As shown in FIG. 7, a plurality of outer peripheral ends of the fixed disk 110 are provided so as to protrude radially with respect to the inner peripheral wall 20a of the hopper 20, in this example, a pair of mounting positions provided at positions opposed to each other by 180 °. It is placed and fixed on the section 112.

  The drive shaft 42 passes through the center of the fixed disk 110. A turntable 114 is attached to the drive shaft 42 that penetrates. The rotating disk 114 is smaller in diameter than the fixed disk 110 and is rotatably mounted on the upper surface of the fixed disk 110. The rotating disk 114 is integrated with the drive shaft 42 by the shaft support means 60 attached to the tip of the drive shaft 42. The main body of the hammer mechanism 120 is connected to the left and right ends of the turntable 114.

  The main body of the hammer mechanism 120 includes a pair of hammers 122 (122a, 122b) placed on the fixed disk 110 and a pair of connecting chains 124 (124a, 124b) that connect the hammer 122 to the rotating disk 114. Is done. Since the hammer 122 is connected to the turntable 114 by the connecting chain 124, the hammer 122 is attached to the turntable 114 so as to be swingable. A crushing blade 58 similar to that described above is attached to the inner peripheral wall 20a of the hopper 20 facing the hammer 122.

  The rotational force from the drive shaft 42 is transmitted only to the turntable 114, and the garbage put into the hopper 20 is cooperated by the crushing blade 58 and the swingable hammer 122 by the rotation of the drive shaft 42. The garbage that has been crushed and crushed by the action falls from the valley of the crushing blade 58 to the bottom 22 of the hopper, and is discharged to the drain outlet 24 side along with the crushed water.

  Although the outer peripheral surface of the fixed disk 110 shown in FIG. 7 is flat, this uneven | corrugated | grooved part can also be functioned as a crushing blade by attaching | subjecting an unevenness | corrugation to the outer peripheral edge of the fixed disk 110 which opposes the crushing blade 58. FIG. In addition, the concavo-convex portion can be made to function as a drop concave portion for dropping the crushed material.

  It goes without saying that also in the third embodiment, the shaft support means 60 shown in the first and second embodiments can be adopted.

  Even in such a chain mill type disposer device 100 having the second type hammer mechanism 120, the rotary table 114 including the hammer mechanism 120 can be easily removed from the hopper 20 by removing the shaft support means 60. The same effect as in Example 1 and below can be obtained. It can be easily understood that a similar effect can be obtained even with a chain mill type disposer device having a first type hammer mechanism.
