Description

  The present invention relates to a lid applicable to a disposer attached to a sink of a kitchen. Specifically, the center portion is recessed in a circular shape to form a water reservoir portion, and the outer peripheral portion is a lid main body that forms an annular collar portion that is positioned higher than the water reservoir portion, and a first hole that is opened inside the outer edge portion of the collar portion. And the height of the outer edge of the collar is set to be equal to or lower than the height of the first water passage so that the water film can be held on the entire top surface of the lid body. Therefore, it is possible to reduce the amount of noise leaking from the smashing chamber of the disposer to the sink side.

  At present, disposers are sometimes laid on sinks such as kitchens in commercial houses and commercial kitchens. The disposer is a device that is attached mainly under the sink and crushes garbage such as garbage thrown in from the sink and discharges it together with water.

  Previously, problems such as contamination of sewage by crushed dredges were pointed out, but some local governments now accept the installation of disposers that meet certain standards. Furthermore, in a housing complex such as an apartment, a drainage system has been introduced in which a common wastewater treatment tank is provided to purify the water discharged from the disposer and then flow into the sewage. Disposers are expected to be more popular in the future because disposers can process garbage immediately and are highly convenient for users, and local governments can reduce the time and effort of collecting garbage.

  However, the disposer crushes the claw thrown into the crushing chamber with a rotating crushing blade, crushing hammer, crushing unit, etc., and there is a problem that a large noise is generated during crushing processing. In order to prevent these noises from leaking out to the kitchen side, many disposers have devised to improve the soundproofing of the open / close lid that closes the crushing chamber. However, the opening / closing lid requires a water passage hole through which water can be supplied at all times for water supply during crushing treatment or drainage for hand washing or dishwashing, which hinders improvement in soundproofing.

  In relation to this, a pulverizing apparatus shown in Patent Document 1 is disclosed. According to this pulverization processing apparatus, a water receiver having a concave cross-section disposed in a state where a predetermined interval is provided under a lid body having a water passage in the central portion, and a soundproofing surface is provided on the upper surface of the water receiver. A water film is formed. Further, the water receiver has a locking member and is configured to be detachable from the lid body. Further, an annular peripheral wall is provided on the outer periphery of the lower side of the lid body and leaks from the water receiver. The water is led to the crushing part (slag crushing chamber). In addition, an annular plate (flange) provided on the outer peripheral portion of the lid body and forming an engagement portion with the drain port is disposed at a position higher than the upper surface of the sink 1 or the water flow port and the through hole.

JP 2004-66032 A (7th and 8th pages, FIG. 2)

  By the way, according to the cover body of the grinding | pulverization processing apparatus shown in patent document 1, the structure of the cover body which has a water receiving body is comparatively complicated, and there exists a possibility that manufacturing cost may become high. Moreover, since the position of a flange is higher than a water flow opening and a through-hole, the circumference | surroundings of a flange are not sealed by the water supply from a faucet, but the exit of the air from a crushing chamber is ensured on the outer periphery of a flange. As a result, the water supply speed to the crushing chamber is increased, and there is a possibility that the water film cannot be held when sufficient water is not supplied from the faucet. In addition, even when sufficient water is supplied from the faucet, there is a problem that the water film cannot be held unless the water film formation is considered in the structure of the lid.

  Accordingly, the present invention has been created in view of the above-described problems, and a lid that can devise a water film forming method to reduce the amount of noise leaking to the sink side without complicating the structure. The purpose is to provide.

Accordingly, the water that flows into the water reservoir from the sink side and overflows from the water reservoir closes the first water passage hole and the outer edge of the flange substantially simultaneously.

According to the lid according to the present invention, together forming a water reservoir recessed central portion, in the high have position than the outer peripheral portion is water reservoir in the lid body constituting the flange portion of the annular opening to the inside of the flange portion The first water-passing hole is provided, the water reservoir is configured as a surface continuous with the flange, and the height from a predetermined reference surface serving as a height reference to the upper surface of the outer edge of the flange is high. a shall have been set from the predetermined reference plane below height reaching the upper surface of the first water passage hole.

  With this configuration, the water that flows into the water reservoir from the sink side and overflows from the water reservoir closes the first water passage hole and the outer edge of the collar portion substantially simultaneously. Therefore, while supplying the crushed water required for the crushing process from the first water passage hole, the outer edge of the lid body is covered with the water overflowing from the water reservoir, The air outlet can be made small. Thereby, a water film can be hold | maintained on the cover main body upper surface over the whole surface, and the noise amount which leaks out from a crushing chamber to the sink side can be reduced.

  Next, the lid according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing a configuration example of the disposer 1.

The member is suspended to the sink flange 51 side together with the hopper 3. The auxiliary spring portion is constituted by three tension springs provided at intervals of 120 °, for example.

  Inside the hopper 3, a cylindrical housing 4 is mounted so as to be detachable from the hopper 3. A crushing unit 10 is mounted in the housing 4. The crushing unit 10 has the third rotary crushing blade 16 at the lowermost stage, and a fitting portion 37 provided on the lower surface of the hub is fitted to a drive shaft 6c of a speed reduction unit (not shown).

  The lower part of the hopper 3 which is the apparatus main body is a housing (case) for fixing to the kitchen sink S, and a drive motor and a speed reduction unit as drive means are installed in the housing (not shown). The drive motor rotationally drives the rotary crushing blade of the crushing unit 10 via the speed reduction unit. Although details are not shown, the drive shaft 6c for transmitting the driving force to the crushing unit 10 has a fitting portion 37 with the crushing unit 10 formed in a square shaft shape or a spline shaft shape.

  FIG. 2 is a perspective view illustrating a configuration example of the housing 4. As shown in FIG. 2, the housing 4 is an upright cylindrical tubular body, and on its inner peripheral surface, in this example, is positioned 180 ° apart, and extends downward from the garbage input opening side. A pair of existing fitting portions (groove portions in this example) 4a is formed. The crushing unit 10 is configured to be detachable from the hopper 3 by being inserted and removed from the input opening 7a.

  As shown in FIG. 1, a drain pipe connection port 6 b is provided at the lower end of the hopper 3. Inside the hopper 3, a bottom plate 6a inclined toward the drain pipe connection port 6b is provided, and the center portion of the bottom plate 6a serves as a bearing portion that receives the drive shaft 6c of the reduction unit.

  The opening of the hopper 3 is communicated with the opening of the sink flange 51 through a joint rubber 90, and the opening / closing lid 8 is detachably attached to the inner periphery thereof. When using the disposer 1, the opening opening side is closed by the opening / closing lid 8, so that non-crushed materials such as foreign substances do not enter the hopper 3 (housing 4) during the garbage treatment and are crushed. The garbage that has been collected is prevented from scattering to the kitchen sink S side.

  The drive motor is started in conjunction with the opening / closing lid 8. Therefore, the disposer 1 includes detection means for detecting that the closing opening 7a is closed by using, for example, three permanent magnets 52 provided on the opening / closing lid 8. For example, when it is detected that the closing opening 7a is closed by the magnetic sensor 55 provided on the outer periphery of the sink flange 51, the driving of the drive motor and the like are controlled by a control means (not shown).

  Here, an example of the attaching means 2 of the disposer 1 to the kitchen sink S will be described with reference to FIG. The attachment means 2 has a sink flange 51. The sink flange 51 includes a body portion 51b to which a flange 51c to which a metal disc-shaped cover member is attached is connected. A thread groove is cut in the outer peripheral surface of the body 51b, and the sink nut 54 is screwed into the body 51b from the lower side in a state where the sink base 53 is fitted in the kitchen sink S. The sink base 53 is attached and fixed to the kitchen sink S by tightening the sink nut 54 against the kitchen sink S.

  The sink base 53 has engagement pieces 56 formed at intervals of approximately 120 °, and includes a main body mounting bracket portion 58. Thus, the sink flange 51 is attached and fixed to the kitchen sink S as the attachment means 2.

  FIG. 3 is a schematic sectional view showing the relationship between the hopper 3 and the housing 4. Both the hopper 3 and the housing 4 are cylindrical bodies, and the housing 4 is smaller in diameter than the hopper 3 and is mounted in the hopper 3 with a small clearance. This small gap that forms the ring also functions as a tap water drainage channel 100. The width Wa (gap) of the drainage channel 100 is sufficient if it is about 1 to 2 mm. In FIG. 3, the crushing unit 10 in the housing 4 is omitted.

  The housing 4 is attached and fixed to the hopper 3. A pair of fixing means 5 for the housing 4 to the hopper 3 when the housing is mounted is provided. In this example, a bulging portion 5a having a predetermined width provided on the hopper 3 side and a pair of ridges 5b provided on the outer peripheral surface of the housing 4 with respect to the bulging portion 5a are provided. The By providing the pair of fixing means 5 at positions opposed to each other by 180 °, the mounting position of the housing 4 can be fixed and the rotation of the housing 4 can be prevented when the disposer 1 is in operation.

  A fitting portion 4 a is formed in the housing 4 at a position 90 ° away from the fixing means 5, and a mounting plate (pressing plate) 95 inserted into the fitting portion 4 a is fixed to the housing 4. As a result, the crushing unit 10 is rotatably mounted in the housing 4.

  4-8 shows an example of the crushing unit 10 applicable to this invention. The crushing unit 10 is composed of a plurality of crushing blades. In this example, a total of five crushing blades of a first rotary crushing blade 12, a first fixed crushing blade 13, a second rotary crushing blade 14, a second fixed crushing blade 15 and a third rotary crushing blade 16 are stacked in this order. Thus, the crushing unit 10 is configured.

  As shown in FIG. 1, the first rotary crushing blade 12, the first fixed crushing blade 13, the second rotary crushing blade 14, the second fixed crushing blade 15, and the third rotary crushing blade 16 have almost no vertical spacing. So that the crushed garbage does not enter the gap above and below the crushing blade and remain in the crushing unit 10.

  4 shows a configuration example of the first rotary crushing blade 12 arranged at the uppermost stage of the crushing unit 10, FIG. 4A is a top view thereof, FIG. B is a front view, and FIG. C is a side view of FIG. is there. The first rotary crushing blade 12 includes a single stirring arm 20 that extends horizontally from the side portion of the bearing portion 19. As for the 1st rotation crushing blade 12, the pressing surface 20a is formed in the front and back both surfaces in the rotation direction of the stirring arm 20. As shown in FIG.

  The pushing surface 20 a is an inclined surface (tapered surface) inclined in a direction in which the upper end protrudes from the lower end on both side surfaces of the stirring arm 20. By forming the pushing surfaces 20a on both side surfaces of the agitating arm 20, the first rotary crushing blade 12 can apply a pressing force to the garbage that is in contact with the pushing surface 20a by bidirectional rotation. it can. Thereby, the 1st rotation crushing blade 12 takes in garbage by rotation operation, and pushes it into the crushing blade of a lower stage.

  Moreover, the edge 20b is formed in the lower end side of the both sides | surfaces of the pushing surface 20a, and the 1st rotation crushing blade 12 is a crushing blade which crushes garbage roughly in cooperation with the 1st fixed crushing blade 13 shown in FIG. Function.

  A handle 21 is formed on the upper surface of the stirring arm 20 in the first rotary crushing blade 12. The handle 21 is provided at a position 90 ° away from the stirring arm 20 so as to extend from the bearing portion 19 to the left and right by the same length. The handle 21 functions as a grip (handle) when pulling up the crushing unit 10.

  Since the handle 21 is used as a gripping portion, the handle 21 is selected to have a length enough for a finger. The bearing portion 19 is provided with an insertion hole 19a through which a shaft head (locking portion) of a rotary drive shaft 36 provided in the third rotary crushing blade 16 described later can be inserted. The insertion hole 19a has a D-shaped cross section. Accordingly, the corresponding portion of the rotary drive shaft 36 is also formed in a D-shaped cross section so that both are rotationally integrated.

  FIG. 5 shows a configuration example of the first fixed crushing blade 13 disposed in the lower stage of the first rotary crushing blade 12, FIG. 5A is a top view, FIG. 5B is a front view, and FIG. The first fixed crushing blade 13 includes two arms 23 extending horizontally from the hub 22 at intervals of 180 °. Each arm 23 has a flat plate shape, and edges are formed on upper and lower ends of both side surfaces, and functions as a crushing blade in cooperation with the first rotary crushing blade 12 and the second rotary crushing blade 14 described above.

  Each arm 23 is provided with a tab 24 that functions as a rotation preventing means at each tip. By fitting the tab 24 to the fitting portion 4 a of the housing 4, the rotation of the first fixed crushing blade 13 is restricted. In this example, a long tab having an entire length selected in consideration of the mounting position (depth) of the first rotary crushing blade 12 with respect to the hopper 3 is used.

  In this example, a tab 24 extending below the arm 23 is provided. As shown in FIG. 5C, the width of the tab 24 is selected to be substantially the same as the width of the fitting portion 4a. This is to reduce backlash after the tab 24 is mounted on the fitting portion 4a and to more smoothly engage the tab 24 with the fitting portion 4a.

  When the second rotary crushing blade 14 is interposed between the first fixed crushing blade 13 and the second fixed crushing blade 15 by the tab 24, a gap having a predetermined height is formed. Therefore, in this example, the length of the tab 24 is selected to be approximately ½ of the length to the cutting edge of the second rotary crushing blade 14.

  The diameter of the inner hole 23a of the hub 22 is larger than the diameter of the shaft part of the second rotary crushing blade 14 and the diameter of the rotary drive shaft 36, and the dimension does not interfere with the shaft part of the second rotary crushing blade 14 and the rotary drive shaft 36. It has become.

  FIG. 6 shows a configuration example of the second rotary crushing blade 14. The second rotary crushing blade 14 is disposed in the lower stage of the first fixed crushing blade 13. 6A is a top view thereof, and FIG. 6B is a cross-sectional view taken along arrow A1-A1 thereof.

  The second rotary crushing blade 14 includes three arms 28 that extend radially from the hub 27 at intervals of 120 °. Each arm 28 has a radius slightly shorter than the inner diameter of the hopper 3 so as not to contact the inner wall of the hopper 3. Each arm 28 is formed with a comb tooth portion 28a having a predetermined pitch on the bottom surface.

  An engagement hole 27 a is formed at the center of the hub 27 of the second rotary crushing blade 14, and the rotary drive shaft 36 is fitted, whereby a rotational force is applied to the second rotary crushing blade 14. Therefore, like the second rotary crushing blade 14, the engagement hole 27 a that comes into contact with the second rotary crushing blade 14 is non-circular (for example, a square hole) so as to be rotationally integrated with the rotary drive shaft 36. The cross section may have a D shape as described above.

  FIG. 7 shows a configuration example of the second fixed crushing blade 15. The 2nd fixed crushing blade 15 is arrange | positioned in the lower stage of the 2nd rotary crushing blade 14 so that it may mesh with the 2nd rotary crushing blade 14. FIG. 7A is a top view, and FIG. 7B is a cross-sectional view taken along line A2-A2.

  The second fixed crushing blade 15 has a shape in which a ring 33 surrounds eight arms 31 extending radially in a tangential direction from the hub 30 at equal intervals. A pair of tabs 33 a are formed on the outer periphery of the ring 33 at intervals of 180 °. The pair of tabs 33 a function as rotation preventing means for fixing the second fixed crushing blade 15 to the housing 4. Therefore, the pair of tabs 33a is formed as a plate that is slightly narrower than the width so that the tabs 33a can be fitted into the fitting portion 4a. This width is substantially the same as the width of the tab 24 of the first fixed crushing blade 13. The rotation of the second fixed crushing blade 15 is regulated by fitting the tab 33a to the fitting portion 4a.

  These tabs 33a have a predetermined height, and the tab 24 of the first fixed crushing blade 13 is in contact with the upper surface of the tab 33a, so that the gap between the first fixed crushing blade 13 and the second fixed crushing blade 15 is reached. A gap having a predetermined height is formed, and the size is selected so that the second rotary crushing blade 14 is just engaged. The center hole 30a of the hub 30 is dimensioned so as not to interfere with the rotation drive shaft 36.

  Of the eight arms 31, the second fixed crushing blade 15 has a comb tooth portion 31a formed on the upper surface of the six arms 31. The comb tooth portion 31a of the second fixed crushing blade 15 has a pitch that meshes with the comb tooth portion 28a of the second rotary crushing blade 14 shown in FIG. 6, and overlaps the second rotary crushing blade 14 and the second fixed crushing blade 15. As a result, the comb teeth portions 28a and 31a are in an engaged state in which a slight gap is formed.

Thereby, the comb tooth portion 31a of the second fixed crushing blade 15 crushes the garbage sent from the upper crushing blade in cooperation with the comb tooth portion 28a of the second rotary crushing blade 14.
As described above, since the number of the arms 28 of the second rotary crushing blade 14 is three and the number of the arms 31 of the second fixed crushing blade 15 is eight, the distance between the arms 31 is narrower than the distance between the arms 28.

  For this reason, when the comb tooth portions 31a are provided on all the eight arms 31, the comb tooth portions 31a of the second fixed crushing blade 15 always exist between the arms 28 of the second rotary crushing blade 14, and a certain degree When the block-shaped garbage of a magnitude | size is thrown in, the situation which the garbage does not enter between the arms 28 of the 2nd crushing blade 14 and becomes difficult to crush occurs.

  Therefore, in the second fixed crushing blade 15, among the eight arms 31, for example, the two arms 32 are not provided with the comb-tooth portion 31 a, so that the second rotary crushing blade 14 is rotated during the rotation operation. 2 When the arm 31 not provided with the comb tooth portion 31a of the fixed crushing blade 15 is positioned between the arms 28 of the second rotary crushing blade 14, a wide space is formed in the circumferential direction.

  Thereby, even when block-shaped garbage having a certain size is introduced, the garbage enters between the arms 28 of the second rotary crushing blade 14, and the comb tooth portion 28 a is rotated by the rotation of the second rotary crushing blade 14. And the garbage is crushed in cooperation with the comb tooth portion 31a of the other arm 31 of the second fixed crushing blade 15.

  In addition, since the crushing ability is reduced when the number of the arms 31 that are not provided with the comb-tooth portions 31a is large in the second fixed crushing blade 15, for example, when the eight arms 31 are provided, the arms 32 that are not provided with the comb-tooth portions 31a. As shown in the drawing, about two are preferable.

  Each arm 32 extends radially along the tangential direction of the hub 30 so that when the second rotary crushing blade 14 rotates, the meshing point with the second fixed crushing blade 15 is shifted in the circumferential direction, The crushing load peak is suppressed and the load is flattened.

  As shown in FIG. 7A, the second fixed crushing blade 15 has pressing surfaces 31 b and 32 a formed on the side surfaces located on the rotation direction side among the side surfaces of the arms 31 and 32. The pressing surfaces 31b and 32a are both wave-like wavefronts, and are formed as wavefronts having a taper whose lower end is shorter than the upper end. By making the pressing surfaces 31b and 32a into wavefronts, the garbage is captured by the concave portions having the taper, and the movement of the garbage in the radial direction is suppressed, so that the garbage can be reliably crushed.

FIG. 8 shows a configuration example of the third rotary crushing blade 16, FIG. 8A is a top view thereof, and FIG. 8B is a front view thereof.
The third rotary crushing blade 16 is configured as a circular plate 35, and a large number of slits 35a are arranged on the entire surface of the circular plate 35 excluding the hub 36 which is a central rotational drive shaft. In the third rotary crushing blade 16 of this example, a plurality of slit groups are formed, and in each slit group, adjacent slits 35a are arranged substantially in parallel.

  The upper surface of the third rotary crushing blade 16 is a flat surface and rotates while contacting the bottom surface of each arm 31 of the second fixed crushing blade 15. The slit 35a penetrates the third rotary crushing blade 16 from the front and back, and a sharp edge is formed at the upper opening side opening edge of the slit 35a.

  The upper surface of the third rotary crushing blade 16 rotates while rubbing against the bottom surface of the arm 31 of the second fixed crushing blade 15, but one side of the arms 31 and 32 of the second fixed crushing blade 15 is inclined to the bottom surface side. Since the wave fronts 31b and 32a are formed, the third rotary crushing blade 16 rotates the third waste crushing blade 16 in contact with the garbage (that is crushed to a certain size) in contact with the wave fronts 31b and 32a. A force for pressing the rotary crushing blade 16 can be applied.

Garbage that has been crushed by the comb tooth portion 28a (FIG. 6) of the second rotary crushing blade 14 and the comb tooth portion 31a (FIG. 7) of the second fixed crushing blade 15 and dropped onto the upper surface of the third rotary crushing blade 16 Although caught in the slit 35a, the garbage is pressed against the slit 35a by the wave fronts 31b and 32a as the third rotary crushing blade 16 rotates. The garbage is crushed by the edge portion of the slit 35a by this rotation operation. The finely crushed food waste falls downward through the slit 35a, passes through the bottom plate 6a of the hopper 3, and is discharged from the drain pipe connection port 6b to the outside.
In addition, the slit 35a forms the opening part (or opening step part) which becomes wide toward the bottom face side, so that the garbage pushed into the slit 35a easily falls.

  A rotary drive shaft 36 is integrally formed with the disk 35 at the center of the third rotary crushing blade 16. The rotary drive shaft 36 is rotationally integrated with the first and second rotary crushing blades 12 and 14 and is rotationally free with respect to the first and second fixed crushing blades 13 and 15. It is made into a shape. Therefore, the rotary drive shaft 36 corresponding to the first and second rotary crushing blades 12 and 14 is a square shaft portion (fitting shaft portion), and the rest are round shafts. And the screw part is cut in the axial head, and it is comprised so that it may function as the latching | locking part 36a.

  A fitting portion 37 that functions as a part of the rotation drive shaft 36 is provided on the lower surface of the disc 35, and is configured to be rotated and engaged with the drive shaft 6c of the reduction unit described above. In order for the fitting portion 37 to be in a good fitting state with the drive shaft 6c, the inner hole 37a is a square hole or a hexagonal hole. The latter is illustrated in FIG. It is assumed that the fitting length of the fitting portion 37 is selected so that the fitting portion 37 is in a sufficiently fitted state with the drive shaft 6c of the speed reduction unit.

  A crushing unit 10 in which a plurality of crushing blades 12 to 16 are integrated is obtained by screwing and tightening a screw 29a from an upper end of a locking portion 36a that is a shaft head of the rotary drive shaft 36 (FIG. 1). reference). At this time, the tabs 24 of the first fixed crushing blades 13 and the tabs 33a of the second fixed crushing blades 15 are integrated in a state where their positional relationships are adjusted so that they are continuous (in a straight line).

  Then, when the crushing unit 10 is lowered to the bottom surface of the housing 4 with the tabs 24 and 33a fitted along the fitting portion 4a, the fitting portion 37 provided on the third rotary crushing blade 16 is illustrated. 1 is fitted to the drive shaft 6c of the speed reduction unit shown in FIG. A presser plate 95 is attached to the fitting portion 4 a, and the presser plate 95 is fixed to the housing 4.

  Thus, the crushing unit 10 is rotatably attached to the housing 4. The crushing unit 10 crushes garbage while repeating normal rotation and inversion. The crushing unit 10 is configured as described above. Hereinafter, a configuration example of the sink flange 51 provided on the upper side of the disposer 1 and to which the opening / closing lid 8 is attached will be described.

  9A and 9B are diagrams showing a configuration example of the sink flange 51. FIG. The sink flange 51 shown in the top view of FIG. 9A is such that the upper side is fitted and fixed to the kitchen sink S, and the members assembled on the hopper 3 side from the lower side of the sink are connected together with the hopper 3.

  9B shown in FIG. 9A, the upper end of the sink flange 51 is provided with a flange 51c that protrudes outward, and the barrel 51b extends below the upper end. ing. The inside of the trunk portion 51b constitutes a closing opening 7a that is a bag charging portion of the disposer 1. On the outer peripheral surface of the body 51b, a thread groove 51d is cut in a predetermined portion on the upper side so as to be screwed into the sink nut 54 described above. A fitting recess 51e with the joint rubber 90 is provided around the outer peripheral portion on the lower side of the body portion 51b.

  On the other hand, a lock flange 57 (57a to 57d) as a locking means for the opening / closing lid 8 is provided on the inner peripheral surface of the trunk portion 51b. The four lock flanges 57 are provided in a circular arc shape having a predetermined gap and projecting substantially horizontally at the same height. The gaps formed between the lock flanges 57a to 57d constitute a fitting groove portion 57e and a housing insertion / extraction groove portion 57f, respectively. The groove portions 57e and 57f are arranged in pairs at an interval of 180 ° when viewed from the upper surface. In this way, the sink flange 51 is configured.

  10A and 10B are diagrams showing a configuration example of the opening / closing lid 8 as the first embodiment. The open / close lid 8 shown in the top view of FIG. 10A constitutes an example of a lid body, and is attached to the sink flange 51 of the disposer 1 to prevent the soot from jumping out from the soot crushing chamber 7 during the crushing process and 10. The crushing sound, driving sound, etc. from the driving motor and the deceleration unit are prevented from leaking to the kitchen side. Further, the open / close lid 8 also functions as a lid switch, and is configured to be able to drain water when it is mounted other than during crushing.

  The opening / closing lid 8 has a central portion that is recessed in a circular shape as an example and forms a water reservoir 60 as shown in FIG. 10A in FIG. 10A, and the outer peripheral portion is positioned higher than the water reservoir 60. It has a lid body 8 ′ that forms an annular flange 61. In addition, although the hollow of the water reservoir 60 may be polygonal instead of circular, it is preferably circular.

The lid body 8 ′ is formed in a substantially plate shape, and a cylindrical body 67 formed integrally is provided below the lid body 8 ′.
The open / close lid 8 is engaged with the sink flange 51 so that a flange outer edge portion 61 a that is an outer peripheral portion of the flange 61 and an edge portion is in contact with the inner surface of the sink flange 51. In addition, a through hole 68a, which is an example of a first water passage hole, is opened in a predetermined portion of the flange 61 located inside the flange outer edge portion 61a. The through-holes 68a are through-holes that guide water from the faucet to the side of the crushing chamber 7, and here, twelve rectangular holes are provided.

  The flange 61 has a substantially horizontal disk shape, and the through hole 68a and the flange outer edge portion 61a are set to substantially the same height H1. Here, the height H1 is a height relative to a predetermined reference plane of the height H0, and indicates the height of the upper surface of the opening of the through hole 68a and the upper surface of the flange outer edge portion 61a.

  The water reservoir 60 configured as a surface continuous with the flange 61 on the inner side of the flange 61 has a bottom surface plate portion 62 having a height H2 lower than the flange 61 at the bottom portion. A through hole 68b is formed as a second water passage hole for guiding water to the side of the crushing chamber 7. The through holes 68b are circular holes, and eight are provided here. The through hole 68b provided at the height H2 is positioned lower than the through hole 68a at the height H1.

  In addition, the flange 61 has a pair of gaps that are 180 ° apart from each other and the outer peripheral part has a predetermined shape and is recessed in a concave shape. Engagement projections 63 a and 63 b that are substantially parallel to the flange 61 are projected. The engaging convex portions 63 a and 63 b are provided at a low position having a gap W <b> 1 in the height direction with respect to the flange 61.

  The opening / closing lid 8 is mounted from the kitchen sink S side at a rotation angle such that the positions of the engaging convex portions 63 a and 63 b are aligned with the groove portion 57 e of the sink flange 51. At this time, the opening / closing lid 8 is fitted to a depth at which the outer periphery of the flange 61 is placed on the upper surfaces of the lock flanges 57a to 57d.

  When the opening / closing lid 8 fitted in the sink flange 51 is rotated, the lock flanges 57a to 57d enter the gap W1, and the lock flanges 57a to 57d are sandwiched between the flange outer edge portion 61a and the engaging convex portions 63a and 63b. The In this way, the opening / closing lid 8 is attached and fixed to the sink flange 51. In addition, a handle (gripping part) 69 is provided at the center of the bottom plate part 62 in order to operate mounting and turning of the opening / closing lid 8.

  11A and 11B are a bottom view illustrating a configuration example of the body portion 67 and a cross-sectional view taken along line A5-A5 in FIG. 11A. In the body portion 67 shown in FIG. 11A, three case portions 66 having a watertight structure are provided here, and the permanent magnets 52 are accommodated therein (FIG. 11B). The case portion 66 is formed at a predetermined position corresponding to the magnetic sensor 55 provided on the outer peripheral portion of the sink flange 51 (see FIG. 1).

  The magnetic sensor 55 of the disposer 1 detects the rotation position of the opening / closing lid 8 that is rotated, and controls ON / OFF of the crushing process by the crushing unit 10. Here, the rotation position of the opening / closing lid 8 is a position where the crushing process is turned off and a position where it is turned on. Thus, the opening / closing lid 8 functions as a lid switch. The opening / closing lid 8 is configured as described above. The soundproof function of the opening / closing lid 8 will be described below.

  12A to 12C are schematic cross-sectional views showing examples of functions of the opening / closing lid 8. The open / close lid 8 shown in FIG. 12A is attached to the sink flange 51 of the disposer 1. When the crushing process is executed by the manual water supply type disposer 1, water is supplied by manually operating a faucet provided in the vicinity of the kitchen sink S. The water supply speed at this time is set to about 8 l / min, for example. Water to be supplied flows from the kitchen sink S into the crushing crushing chamber 7 through the opening / closing lid 8 as indicated by the broken arrow line.

  The disposer 1 starts the crushing process when the opening / closing lid 8 attached to the input opening 7a is rotated to the rotation position where the crushing process is turned on, and rotates the crushing unit 10 at a speed of, for example, 100 to 200 rpm. Let The soot crushed in the crushing crushing chamber 7 is discharged from the drain pipe connection port 6b through the bottom plate 6a of the hopper 3 by the water supplied to the crushing crushing chamber 7 (see FIG. 1).

  At this time, the water supplied from the faucet first flows into the upper surface of the water reservoir 60, which is the lowest position of the open / close lid 8, as shown in FIG. 12A. Here, if the amount of water supplied is larger than the amount of water flowing from the through-hole 68b to the side of the crushing chamber 7, water accumulates on the upper surface of the water reservoir 60 as shown in FIG. 12B. 12B and 12C show the through hole 68b and the flange outer edge portion 61a in an enlarged manner.

  As shown in FIG. 12C, the water overflowing the water reservoir 60 after being filled with the water reservoir 60 is guided to the upper surface of the flange 61 and flows into the crushing crushing chamber 7 side through the through holes 68a. The through hole 68a and the flange outer edge portion 61a provided in are closed at the same time. At this time, the water film M1 provided on the upper surface of the opening / closing lid 8 seals the through hole 68a, the through hole 68b, and the flange outer edge portion 61a. The water film M <b> 1 functions as a soundproof film that blocks sound from the crushing chamber 7.

  By the way, the crushing chamber 7 is sealed with a drain pipe trap (not shown) whose lower side is connected to the drain pipe connection port 6b. In addition, the open / close lid 8 that closes the upper side is in a state where there is almost no air outlet because the upper surface including the flange outer edge portion 61a is sealed with the water film M1. Therefore, the inflow speed of water flowing into the crushing crushing chamber 7 from the through holes 68a and 68b is relatively slow. As a result, the water film M1 is held at a predetermined thickness.

  However, the soot crushed by the crushing unit 10 flows out from the lower drainage pipe by its own weight or slowly supplied water, and is eventually discharged together with the trap water in the drainage pipe trap. At this time, the crushing crushing chamber 7 becomes negative pressure, and a water absorption phenomenon that strongly draws water from the kitchen sink S side may occur. When the water absorption phenomenon occurs, it is assumed that the water film M1 on the opening / closing lid 8 is broken and the soundproof water seal is released.

On the other hand, in the crushing process by the disposer 1, a large crushing sound is generated in the first half when a large cocoon is crushed.
FIG. 13 is a diagram illustrating a crushing process example of the disposer 1, where the horizontal axis indicates the crushing time for executing the crushing process, and the vertical axis indicates the rotation speed of the crushing unit 10. In the disposer 1 of this example, the normal rotation speed of the crushing unit 10 is set to 140 rpm. In the crushing process shown in FIG. 13, the crushing unit 10 is rotated at a rotation speed of about 98 rpm, which is about 70% of the normal rotation speed, for 5 seconds from the start of the crushing process. The crushing unit 10 is set to rotate at a normal rotation speed of about 140 rpm for up to 2 seconds. As described above, when the crushing process is executed at a low speed for a predetermined time from the start, the crushing sound in the first half can be reduced, and the crushing chamber 7 is prevented from suddenly becoming negative pressure, and the crushing sound is loud. The water film M1 can be reliably held in the first half of the treatment.

  Of course, the crushing process can also be executed at the normal rotation speed of 140 rpm from the start. Also in this case, since the water supply from the through holes 68a and 68b is relatively slow due to the water film M1, it takes a predetermined time for the crushed soot to flow out of the water distribution pipe. Accordingly, when the crushing chamber 7 is under negative pressure, the crushing process proceeds, and the amount of noise leaking to the kitchen sink S side is often reduced to a level where there is no problem.

  As described above, according to the opening / closing lid 8 according to the first embodiment of the present invention, the annular flange 61 whose central portion is recessed in a circular shape to form the water reservoir 60 and whose outer peripheral portion is higher than the water reservoir 60 is provided. The opening / closing lid 8 is provided with a through hole 68a opened inside the flange 61, and the height of the flange outer edge 61a is set to the same height as the through hole 68a.

  Therefore, the water that flows into the water reservoir 60 from the kitchen sink S side and overflows from the water reservoir 60 blocks the through hole 68a of the flange 61 and the flange outer edge portion 61a almost simultaneously. Thereby, since the exit of the air from the crushing crushing chamber 7 can be made small, the inflow speed of the water which flows into the crushing crushing chamber 7 from the through-hole 68a can be slowed. Accordingly, since the water film M1 can be held over the entire surface of the open / close lid 8, the amount of noise leaking from the smashing chamber 7 to the kitchen side can be reduced.

Further, since the occurrence of water absorption phenomenon can be suppressed for a relatively long time from the start of the crushing process, the soundproof effect can be maintained by holding the water film M1 in the first half of the crushing process with a large crushing sound.
The open / close lid 8 described in detail in the present embodiment can also be applied to a disposer that automatically supplies water from a faucet provided in the kitchen sink S.

  14A to 14C are schematic cross-sectional views showing a configuration example and a function example of the opening / closing lid 208 as the second embodiment. The open / close lid 208 shown in FIG. 14 constitutes an example of a lid, and is engaged with the sink flange 51 of the disposer 1 shown in FIG. The open / close lid 208 engaged with the sink flange 51 closes the cocoon crushing chamber 7 of the disposer 1. In this example, the same names and reference numerals as those in the first embodiment have the same function and the same structure, so that the description thereof is omitted.

  The opening / closing lid 208 has a lid body 208 ′ that forms an annular flange 71 whose central portion is recessed in a circular shape to form the water reservoir 70 and whose outer peripheral portion is positioned higher than the water reservoir 70. A body 77 is integrally extended on the back side of the lid body 208 '.

  The water reservoir 70 has a bottom plate portion having a height H2 from a reference plane having a height H0, and the bottom plate portion is provided with a plurality of through holes 78b as an example of a second water passage hole. . When the opening / closing lid 208 is attached to the disposer 1, the outer peripheral portion of the flange 71 is in contact with the inner surface of the sink flange 51.

  In the opening / closing lid 208 of this example, the flange 71 that constitutes an example of the flange has an inclination that the outer side is lower than the inner side. The outermost edge portion of the flange 71 constitutes a flange outer edge portion 71a, and a through hole 78a, which is an example of a first water passage hole, is provided inside the flange outer edge portion 71a.

  The outer flange outer edge portion 71a is set to a height H1 with respect to a predetermined reference plane having a height H0, and the inner through hole 78a is opened at a position having a height H3 with respect to the predetermined reference plane. Yes. Here, due to the inclination of the flange 71, the outer height H1 is lower than the height H3 of the portion where the inner through-hole 78a is located. That is, the flange outer edge portion 71 a is set lower than the through hole 78 a of the flange 71.

  When water is supplied from the faucet during the crushing process in the manual water supply type disposer 1, first, water flows into the water reservoir 70 from the kitchen sink S side as shown in FIG. 14A. Furthermore, as shown in FIG. 14B, the water that has been supplied and overflowed from the water reservoir 70 first flows into the upper surface of the flange 71 and closes the engaging portion between the flange outer edge portion 71a and the sink flange 51.

  Therefore, when the height of the water film reaches the height H3 of the through-hole 78a, there is no air outlet from the crushing chamber 7 other than the through-hole 78a. Thereby, since the speed of the water supplied from the through holes 78a and 78b to the smashing chamber 7 can be reduced, a water film M2 as shown in FIG.

  Thus, according to the opening / closing lid 208 according to the second embodiment of the present invention, the flange outer edge 71a is positioned lower than the through hole 78a. Therefore, the water film M2 can be reliably formed on the upper surface of the opening / closing lid 208, and the soundproofing effect by the water seal can be maintained.

  FIG. 15 is a perspective view showing a configuration example of an opening / closing lid 308 as a third embodiment.

  The pair of protrusions 59a and 59b is provided at a higher position having a predetermined gap W2 than the arc-shaped lock flange 307 formed integrally with the body portion 301b. An opening / closing lid 308 that closes the upper part of the crushing chamber 7 is formed in the gap W2 by using a gap W2 between the protrusions 59a and 59b formed on the inner peripheral surface of the body 301b of the sink flange 151 and the lock flange 307. The annular flange 81 of the opening / closing lid 308 is inserted and fixed. Further, a groove portion 59f for housing insertion / extraction is provided as a gap portion of the lock flange 307 at a position approximately 90 ° apart from the pair of protrusions 59a, 59b. In this way, the sink flange 151 is configured.

  17A and 17B are diagrams showing a configuration example of the flange 81 and the water passage holes 65a and 65b.

At that time, it is possible to obtain a soundproofing effect by the lid member 44b configured substantially the same as the opening / closing lid 8 of the first embodiment.

  That is, the water supplied from the water supply unit 42 first flows into the upper surface of the lowest water reservoir 40 of the lid member 44b. Here, if the amount of water supplied is larger than the amount of water flowing from the through hole 48 b to the side of the crushing chamber 7, the water accumulates on the upper surface of the water reservoir 40. The water that overflows by filling the water reservoir 40 closes the through hole 48a of the flange 41 and the flange outer edge 41a provided at the same height almost simultaneously. At this time, the water film provided on the upper surface of the lid member 44 b functions as a soundproof film that seals the through holes 48 a, the through holes 48 b, and the flange outer edge portion 41 a, and blocks the crushing sound from the crushing chamber 7.

  As described above, according to the opening / closing lid 408 according to the fourth embodiment of the present invention, the annular flange 41 whose central portion is recessed in a circular shape to form the water reservoir 40 and whose outer peripheral portion is positioned higher than the water reservoir 40 is provided. The lid member 44b is provided with a through hole 48a provided inside the flange 41, and the flange outer edge portion 41a is provided at the same height as the through hole 48a.

  Therefore, since the air outlet on the side of the opening 7a of the smashing chamber 7 can be made small, the inflow speed of the water flowing into the smashing chamber 7 from the through holes 48a and 48b can be slowed. Thereby, since a water film can be hold | maintained over the whole surface of the cover member 44b, the amount of noise which leaks from the crushing crushing chamber 7 to the kitchen side can be reduced.

  FIG. 23 is a perspective view showing a configuration example of an opening / closing lid 508 as a fifth embodiment. The open / close lid 508 shown in FIG. 23 is an example of a lid that can be attached to the automatic water supply type disposer 400, and includes upper and lower lid members 504a and 504b.

Has been. That is, the sink flange 151 is used in place of the sink flange 51 in the disposer 400 to which the opening / closing lid 508 is attached.

  FIG. 24 is a side view showing a configuration example of the lid members 82 and 83 attached to the lid member 504b. The lid members 82 and 83 shown in FIG. 24 are configured as separate members from the opening / closing lid 508, as in the third embodiment. The lid members 82 and 83 in this example are mounted so as to manipulate the opening state of the water passage hole 65a 'of the lid member 504b.

  As shown in FIG. 18B, on the back surface of the lid member 82, a cylindrical portion 82a is provided at one end, and a protrusion 82b is provided at the other end. An operation knob 82c projects from the upper surface of the projection 82b.

  The lid member 82 is attached to the open / close lid 508 by fitting the cylindrical portion 82a into one water passage hole 65b '(left side in FIG. 24). At this time, the lid member 82 blocks the water passage hole 65b '. Further, when the lid member 82 is rotated by the knob 82c with the cylindrical portion 82a as a fulcrum, the protrusion 82b is fitted into one water passage hole 65a ', and the lid member 82 passes through the water passage hole 65a'. It will be blocked.

  Here, the lid member 82 is incorporated between the lid member 504a and the lid member 504b so that the knob portion 82c protrudes from the water passage portion 506 to the upper surface of the lid member 504a. Therefore, the knob portion 82 c can be rotated within the opening range of the water flow portion 506. Thereby, the size of the opening of the water passage hole 65a 'can be adjusted.

  Similarly to the lid member 82, one lid member 83 also has a cylindrical portion 83 a on the back side, a protrusion, and a knob portion 83 c, and is incorporated in the opening / closing lid 508 so that the knob portion 83 c protrudes from the water passage portion 506. ing. The lid member 83 adjusts the size of the opening of the other water flow hole 65a '(the right side in FIG. 24).

  Furthermore, a water conduit 503 communicating with the water supply unit 42 is provided in the lid member 504 b of the opening / closing lid 508. The water guide section 503 is configured substantially the same as the water guide path 43 of the fourth embodiment, and guides water from the water supply section 42 to the upper surface of the lid member 504b. The water conduit 503 has an inclination that the end on the water discharge side that discharges water to the lid member 504 b is higher than the end on the water supply side that communicates with the water supply unit 42.

  A configuration example of the lid member 504a viewed from the back side is shown in FIG. The handle 509 of the lid member 504a shown in FIG. 25 constitutes a concave portion 509 'when viewed from the back side.

  Ribs 501 and 502 are integrally formed with the lid member 504a on the outer peripheral portion of the concave portion 509 '. When the lid members 504a and 504b are connected, the ribs 501 and 502 are provided at positions arranged on the upper surface of the water channel from the water supply unit 42, and guide the water flowing through the water channel into the concave part 509 ′. It is made like.

  Thus, according to the opening / closing lid 508 as the fifth embodiment of the present invention, the ribs 501 and 502 are provided on the back surface of the upper lid member 504a.

  With this configuration, water supplied from the water supply unit 42 of the disposer 400 is guided from the water channel of the lid member 504b to the concave portion 509 ′ of the lid member 504a, so that the course of water is directed to the upper surface of the lid member 504b. Become. Therefore, since water can be efficiently supplied to the upper surface of the lid member 504b, a water film can be held over the entire surface of the lid member 504b, and the amount of noise leaking from the crushing chamber to the kitchen side can be reduced.

  A water passage hole 65a 'provided on the upper surface of the lid member 504b is configured to be selectively sealed by the lid members 82 and 83 which are separate members. Thus, for example, when crushing a small amount of straw, the water passage hole 65a 'is opened to improve the air flow between the inside and the outside of the crushing chamber, and smoothly supply the crushing water to the crushing chamber. Can be done.

  The present invention is very suitable when applied to a disposer attached to a sink such as a kitchen of a general house or a commercial kitchen.
