Description

  The present invention relates to a disposer that can be applied to crushing processing of a cocoon at a kitchen sink. Specifically, the upper housing and the lower housing connected via the elastic tube member and the auxiliary elastic member are provided with an engaging mechanism for temporary holding, and the lower housing is attached to the upper housing during disposer installation work or the like. The elastic tube member and the auxiliary elastic member can be attached with both hands so that the operator can easily and safely perform the operation.

  Currently, disposers are sometimes installed in sinks such as kitchens in general 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 vibration is generated with a large crushing sound during crushing processing.

  In order to reduce the noise caused by such vibrations and to prevent tableware from falling from the sink due to vibrations, many disposers have a disposer body on the upper housing on the sink mounting side and the lower housing on the vibrating portion side. Are separated from each other by anti-vibration rubber or the like to suppress vibration transmitted from the vibrating portion to the sink side.

  Further, when installing the disposer on the sink, it is often the case that a predetermined part of the upper casing is attached to the drain of the sink and then the lower casing is connected to the upper casing from the back side of the sink. Therefore, the shock-proof rubber for cushioning often serves as a connecting part for disposer installation.

  In relation to this, a disposer as shown in Patent Document 1 is disclosed. According to this disposer, a lower housing is attached to a sink flange (upper housing) attached to a sink via a shock-absorbing rubber that prevents vibration transmission, and the lower housing is further connected to a hopper and a bracket. The top and bottom are separated. The separated hopper and bracket are fastened to each other with a plurality of bolts, and the bolts can be buffered by bushes and springs attached to the outer periphery of the shaft portion.

  If comprised in this way, the vibration from the bracket which accommodates a motor housing will be damped, it will become difficult to transmit to a hopper, and it will become possible to prevent the vibration transmission to a sink.

  Further, a disposer mounting device disclosed in Patent Document 2 is also disclosed. According to this disposer mounting device, the disposer (lower casing) is watertightly connected to the sink drain hole via the anti-vibration rubber under the connecting bracket (upper casing) attached by screwing with a nut. In addition to preventing the disposer vibration from being transmitted to the sink, a plurality of spring mounting seats are provided on each of the connecting bracket side member and the disposer side member, and a tension spring is stretched between the spring mounting seats. ing.

  With this configuration, the weight of the disposer is supported by the tension of the spring so that stress other than vibration is not applied to the anti-vibration rubber, so that the anti-vibration rubber can retain its flexibility and improve the anti-vibration performance. It is to become.

The flange 74 is a metal flange that is firmly connected to the hopper 3, and hooking holes 74 a, 74 b, 74 c are opened in a hollow disk-shaped flange plane portion (see FIG. 9 and FIG. 9). 10). For example, the lower hooking portion 61b of the tension spring 61 is attached to the hole 74a.

  Further, the hopper 3 and the sink flange 51 of this example are provided with an engagement mechanism 80 that temporarily holds the hopper side on the sink flange side. Here, two engagement mechanisms 80 are provided on the outer periphery of the disposer 1 at intervals of 180 °. One engagement mechanism 80 is constituted by a sink base side metal fitting 81 and a hopper side metal fitting 82, and the other engagement mechanism 80 is constituted by a sink base side metal fitting 83 and a hopper side metal fitting 84. The Here, the metal bases 81 and 83 on the sink base side constitute an example of an engaged part, and the metal parts 82 and 84 on the hopper side constitute an example of an engaging part.

  The metal fittings 81 and 83 have a metal bowl shape, one end is connected to the sink base 53 on the outer peripheral portion of the sink flange 51, and the other end is extended to the hopper side. The tip of the end is bent for hooking.

  The metal fittings 82 and 84 have one end connected to the flange 74 of the outer peripheral portion of the hopper 3 and the other end extended to the sink flange side, and have the other end extended. The tip is bent so as to be caught by the metal parts 81 and 83.

The engaged portion and the engaging portion of the engaging mechanism 80 are in a position where the hopper side is rotated by a predetermined amount with respect to the sink flange side, for example, a first posture in which the auxiliary spring member 60 is inclined (see FIG. 11) and the relative position between the sink flange side and the hopper side in a normal installation state in which the sink flange side and the hopper side face each other, for example, the second position where the auxiliary spring member 60 is vertical. It is arrange | positioned so that it may not engage in the position which maintains this attitude | position (refer FIG. 12).
The first posture and the second posture indicate the relative positional relationship between the sink flange side and the hopper side, and do not indicate the posture of the auxiliary spring member 60.

  A tub 3 housing 4 is mounted inside the hopper 3 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 and the peripheral part of the hopper 3 which is the apparatus main body are a housing (case) for fixing to the kitchen sink S. Although not shown in the figure, a drive motor and a speed reduction unit are installed as drive means. Is done. In this example, a drive motor or the like is installed in a housing 1 a provided on the side of the hopper 3. 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.

  A drain pipe connection port 6b (not shown) is provided at the lower end of the hopper 3, and a water pipe 6bb shown in FIG. 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 7 is closed by a magnetic sensor (not shown) provided on the outer periphery of the sink flange 51, the drive of the drive motor and the like are controlled by a control means (not shown).

  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 an annular shape functions as a drainage channel 100 for tap water. 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 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 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 upper and lower gaps of 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 part 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 at the 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 threaded part is cut | disconnected 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).

  When the crushing unit 10 is lowered to the bottom surface of the housing 4 in a state where the tabs 24 and 33a are 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 disposer 1 having the crushing unit 10 is configured as described above. Hereinafter, the engagement mechanism 80 of the disposer 1 will be described.

  FIG. 9 is a perspective view of the disposer 1 showing a configuration example of the engagement mechanism 80. In the disposer 1 shown in FIG. 9, the rotation position of the hopper 3 with respect to the sink flange 51 is set to the normal use position (second posture), and the auxiliary spring member 60 is arranged substantially vertically. Two engagement mechanisms 80 are provided on the outer periphery of the disposer 1.

  One engagement mechanism 80 includes a hook-shaped metal member 81 and a metal member 82. The metal fitting 81 of this example is composed of a strip-shaped plate piece (metal piece) whose upper end portion 81 a is continuous with the sink base 53. The metal fitting 81 is bent downward substantially perpendicular to the sink base 53 and extends to the hopper side with a predetermined length. Furthermore, the tip of the extended lower end 81b is bent outward.

  The metal fitting 82 is formed of a strip-shaped plate piece having a lower end portion 82a continuous with the flange 74, is bent upward substantially perpendicularly from the flange 74, and extends to the sink flange side by a predetermined length. The tip of the extended upper end 82b is bent inward.

  The metal fitting 81 and the metal fitting 82 are extended to a position where they can be engaged when the sink flange 51 and the hopper 3 are connected. In this example, since the engagement position is relatively high, the metal fitting 82 is made longer than the metal fitting 81. However, the metal fitting 81 and the metal fitting 82 may have the same length with the engagement position being an intermediate portion. The metal fitting 81 may be longer than the metal fitting 82 by setting the engagement position to a low position.

  By setting the metal fitting 81 and the metal fitting 82 to suitable lengths, the hopper 3 is held at a height that can be connected to the sink flange 51 when the engagement mechanism 80 is engaged. Moreover, the metal fittings 83 and 84 which the other engagement mechanism 80 has are also comprised similarly (refer FIG. 1). The two engagement mechanisms 80 are disposed so as to have an engagement direction different from the expansion / contraction direction of the auxiliary spring member 60. Here, the engaging direction of the engaging mechanism 80 is a direction in which the engaged portion and the engaging portion face each other.

  FIG. 10 is a top view of the disposer 1 showing an arrangement example of the auxiliary spring member 60 and the engagement mechanism 80. The disposer 1 shown in FIG. 10 is in a state in which the lid 8 is removed, and members such as the kitchen sink S, the casing 1a, and the crushing unit 10 are omitted for simplicity. In FIG. 10, the center 0 of the opening 51a of the sink flange 51 and the positions of the holes 71a to 73a and the holes 74a to 74c are indicated by dots.

  The disposer 1 shown in FIG. 10 is in a rotation position (first posture) in which the sink flange 51 and the hopper 3 are relatively rotated by a predetermined amount, such as during installation work, and the engagement mechanism 80 is engaged. ing. Here, the separation angle between the engagement mechanism 80 and the auxiliary spring member 60 (for example, the tension spring 61) is arranged so as to be different in the vertical direction. That is, the separation angle θ1 between the upper metal fitting 81 and the hole 71a and the separation angle θ2 between the lower metal fitting 82 and the hole 74a are set to different angles.

  Here, the separation angle θ1 is an angle formed by a line connecting the center 0 and the metal fitting 81 and a line connecting the center 0 and the hole 71a, and the separation angle θ2 is the center 0 and the metal fitting 82. Is an angle formed by the line connecting the center 0 and the line connecting the center 0 and the hole 74a. Therefore, in the first posture in which the engagement mechanism 80 is engaged, the hole 71a and the hole 74a have a separation angle θ3 (θ1−θ2).

  Further, in this example, the hole 71a and the hole 72a are separated by 115 °, and the hole 71a and the hole 73a are separated by 130 °. Thus, by changing the separation angles of the holes 71a, 72a, 73a, the rotational position of the disposer 1 after installation can be regulated.

  Further, the hole 72a, the hole 74b, and the hole 73a and the hole 74c are arranged with a separation angle θ3 from each other. In this way, by making the separation angles θ3 related to the three tension springs 61 to 63 equal, the sink flange 51 and the hopper 3 face each other as shown in FIG. 2), all of the three tension springs 61 to 63 are arranged substantially vertically. Below, the installation method of the disposer 1 to the kitchen sink S is demonstrated.

  FIGS. 11 and 12 are top views showing installation examples (parts 1 and 2) of the disposer 1, and the kitchen sink S is not shown for the sake of explanation. The sink flange 51 shown in this figure is attached to the kitchen sink S on the upper side.

  When the upper opening of the hopper 3 is connected to the lower opening of the sink flange 51, first, the engagement mechanism 80 is engaged as shown in FIG. At this time, the metal parts 81 and 82 and the metal parts 83 and 84 are arranged vertically so that the bent portions of the metal parts 82 and 84 on the hopper side are hooked on the bent parts of the metal parts 81 and 83 on the sink flange side. At this time, the rotation position of the hopper side with respect to the sink flange side maintains the first posture.

  At this time, one pipe end of the joint rubber 90 is fitted to the opening of the sink flange 51 or the hopper 3 in advance, and the other pipe end is simultaneously engaged with the engagement mechanism 80. Fit into the other opening. At this time, the disposer 1 is in a temporary holding state in which the hopper side is suspended to the sink flange side by the engagement mechanism 80.

  In this state, the auxiliary spring member 60 and the joint rubber 90 are fixed. In this example, first, hose bands 91 and 92 are loosely wound around the pipe end portions 90a and 90b of the joint rubber 90, and are clamped and fixed to such an extent that the hopper side can rotate. At this time, since the hopper side is temporarily held by the engaging mechanism 80, the hose bands 91 and 92 can be attached with both hands.

  Next, the auxiliary spring members 60 (tensile springs 61 to 63) are sequentially attached. For example, the upper hook 61a of the tension spring 61 is hooked in the hole 71a, and the lower hook 61b is hooked in the hole 74a. Here, since the hole 71a and the hole 74a have a separation angle θ3, the auxiliary spring member 60 is attached with an inclination. Also at this time, since the hopper side is temporarily held by the engaging mechanism 80, both ends of the tension springs 61 to 63 can be hooked with both hands.

  When the auxiliary spring member 60 is attached, as shown in FIG. 12, the hopper side member is placed at the relative rotation position (second posture) during normal use in which the three tension springs 61 to 63 are arranged substantially vertically. Rotate. In this relative rotation position, the separation angle θ3 is zero. At this time, the engagement of the engagement mechanism 80 is released, but the hopper side member is suspended by the auxiliary spring member 60 and the joint rubber 90. Therefore, the member on the hopper side can be held with both hands and rotated.

  When the relative rotational position between the sink flange side and the hopper side reaches a predetermined relative rotational position that is a relative rotational position during normal use, finally, the hose bands 91 and 92 are firmly tightened. The disposer 1 can be installed in the kitchen sink S as described above.

  Thus, according to the disposer 1 as the first embodiment of the present invention, the sink flange 51 connected via the joint rubber 90 and the auxiliary spring member 60 and the outer peripheral portion of the hopper 3 can be engaged with each other. An engaging mechanism 80 is provided.

  With this configuration, the hopper 3 can be temporarily held on the sink flange 51 when the disposer 1 is installed. Therefore, when connecting the sink flange 51 and the hopper 3, the operator can use both hands to connect the joint rubber 90 and the auxiliary spring member. 60 can be attached. Therefore, the efficiency of the work can be improved and the work can be safely performed alone.

  Further, since the expansion / contraction direction of the auxiliary spring member 60 and the engagement direction of the engagement mechanism 80 are different, the engagement mechanism 80 does not hinder expansion / contraction of the auxiliary spring member 60 after the disposer 1 is installed. Therefore, the stretchability of the auxiliary spring member 60 and the joint rubber 90 during normal use can be ensured.

  In this example, a pair of engagement mechanisms 80 are provided. However, the present invention is not limited to this, and three or more engagement mechanisms 80 may be provided. In that case, three or more engagement mechanisms 80 may be arranged at equal intervals, but instead of being arranged at equal intervals, the rotational positions of the upper and lower housings may be defined.

  Similarly, in this example, the three tension springs 61 to 63 are provided as the auxiliary spring member 60. However, the present invention is not limited to this, and the number of auxiliary spring members 60 can be changed as appropriate. Further, in this example, the tension springs 61 to 63 are not arranged at equal intervals so that the rotation position of the lower housing can be defined. However, the tension springs 61 to 63 may be arranged at equal intervals. Good.

  In addition, in this example, the tip of the engaged portion is bent outward and the tip of the engaging portion is bent inward, but this is not a limitation, and the tip of the engaged portion is bent inward. Then, the tip of the engaging portion may be bent outward. Alternatively, one may be a belt-like engaged portion that is not bent, and the other may be a hook-like engaging portion. Furthermore, the engaged portion can be disposed in the lower housing and the engaging portion can be disposed in the upper housing.

  A tube-shaped member may be provided on the outer peripheral portion of the spring of the auxiliary spring member 60 so as to cover the expansion / contraction portion of the auxiliary spring member 60. By doing in this way, the outer periphery of the auxiliary spring member 60 and the tubular member are in sliding contact with each other to suppress vibration of the auxiliary spring member 60 and improve the durability of the auxiliary spring member 60.

  Further, by changing the natural frequency of the auxiliary spring member 60 by attaching a tubular member, resonance is avoided when the natural frequency of the auxiliary spring member 60 matches the frequency of the disposer 1. You can also In such a case, the vibration transmitted from the hopper side to the kitchen sink side can be reduced by mounting the tubular member. Further, a buffer member such as a sponge may be inserted into the inner diameter portion of the auxiliary spring member 60 instead of the tubular member.

  FIG. 13 is a schematic cross-sectional view showing a configuration example of a joint rubber 90 'as a second embodiment. The disposer 1 shown in FIG. 13 is in a state after installation, and the joint rubber 90 ′ connects the sink flange 51 and the hopper 3 in a watertight manner. In this example, those having the same names and symbols as in the first embodiment have the same function and the same structure, and therefore the description thereof is omitted.

  The joint rubber 90 'has hose band recesses 93a and 93b at the pipe ends 90a and 90b. The hose bands 91 and 92 wound around the recesses 93a and 93b are restricted from moving in the width direction by the recesses 93a and 93b.

  The joint rubber 90 'has an annular impact absorbing portion 96 between the tube end portion 90a and the tube end portion 90b. The shock absorbing portion 96 is curved so that the inner peripheral surface protrudes in an annular shape, and has an annular recess 97 that is recessed in an annular shape on the back surface side. Therefore, when the housing 4 vibrates, it can be elastically supported by the portion protruding in the tubular shape, and the generation of abnormal noise can be suppressed.

  The annular recess 97 is provided with the outer peripheral surface of the joint rubber 90 ′ recessed inwardly in a U-shape, and a vibration buffering space S <b> 1 from the hopper side is held inside the annular recess 97. Here, the annular recess 97 is recessed to the inside of the opening edge of one of the openings of the hopper 3 or the sink flange 51. In this example, the top of the opening of the hopper 3 is recessed to the inner side of the top 3a that is an impact transmitting portion. Thereby, when the hopper 3 vibrates, an annular recessed part bends and can absorb a vibration efficiently.

  Further, of the inner peripheral surface of the joint rubber 90 ′, the surfaces F <b> 1 to F <b> 3 that come into contact with water from the sink flange 51 are formed so as to be inclined toward the bottom surface of the crushing chamber 7. This makes it difficult for water to collect in the joint rubber 90 ′, so that corrosion, deterioration, etc. of the joint rubber 90 ′ can be prevented, and hygiene can be improved.

  Similarly, the sink flange 51 and the surfaces F4 and F5 of the hopper 3 serving as a joint portion with the joint rubber 90 ′ are also inclined toward the bottom surface of the crushing chamber 7. Here, the surfaces F1 and F4 joined to each other have substantially the same inclination angle, and the surfaces F3 and F5 have substantially the same inclination angle. As a result, the joint portions between the joint rubber 90 ′ and the respective housings are brought into close contact with each other, so that water, garbage, etc. do not enter the joint portions, and it is hygienic and can prevent corrosion deterioration and the like.

  Thus, according to the joint rubber 90 ′ as the second embodiment of the present invention, the space S <b> 1 is provided in the vibration transmission direction of the hopper 3. With this configuration, it is possible to efficiently absorb the vibration from the hopper 3 and reduce the vibration transmitted to the kitchen sink side.

  Furthermore, since the inner surface of the joint rubber 90 'is inclined, water and garbage that come in contact with the joint rubber 90' fall without being deposited. In addition, since the joint portion between the joint rubber 90 'and each casing is in close contact, garbage and water do not enter the joint portion. As a result, deterioration of the joint rubber 90 'can be prevented, vibration isolation can be maintained over a long period, and hygiene can be improved.

  FIG. 14 is a perspective view showing a configuration example of a disposer 200 as a third embodiment. A disposer 200 shown in FIG. 14 is an automatic water supply type garbage disposal machine having a water supply unit for crushing treatment. In this example, those having the same names and symbols as in the first embodiment have the same function and the same structure, and therefore the description thereof is omitted.

  The disposer 200 has a cylindrical hopper 3 into which garbage or the like is charged, and a sink flange 51 is connected to the upper portion of the hopper 3 through a joint rubber 90 in a watertight manner. The sink flange 51 is fitted and fixed to the drain of the kitchen sink S via the attachment means 2.

  The opening of the sink flange 51 forms a charging opening 7a that is a basket charging portion from the kitchen sink S side (see FIG. 1). Further, the inside of the hopper 3 that communicates with the charging opening 7 a forms a crushing chamber 7. A cylindrical housing 4 detachably attached to the hopper 3 is mounted inside the hopper 3. A crushing unit 10 is mounted in the housing 4 and crushes garbage while repeating normal rotation and inversion. The opening on the upper side of the crushing chamber 7 is closed by an opening / closing lid 208. The opening / closing lid 208 is composed of two upper and lower lid members.

  The lid member on the upper side of the opening / closing lid 208 is a flat plate, and a handle is provided at the center. The lower lid member has a bottomed water reservoir, and a plurality of through holes are formed in the bottom surface of the water reservoir. Further, for example, three permanent magnets for detecting rotation are provided in a predetermined portion of the lower lid member, and the open / close lid 208 also functions as a lid switch.

  Further, the disposer 200 is provided with a water supply unit 42 for automatic water supply. The water supply unit 42 has a water supply opening that can be opened and closed in accordance with a predetermined command. The water supply port is arranged so that water can be discharged toward the gap between the two lid members of the opening / closing lid 208. The water supply unit 42 is connected to a water pipe 43 drawn out as a water supply route different from the faucet for the kitchen sink S.

  When the opening / closing lid 208 is rotated to a rotation position at which the crushing process is turned on, the disposer 200 opens the water supply port of the water supply unit 42 and rotates the crushing unit 10. At this time, the water supplied from the water pipe 43 to the water supply unit 42 is supplied from the water supply port to the upper surface of the lid member on the lower side of the opening / closing lid 208 and supplied from the through hole to the cocoon crushing chamber 7.

  Also in the disposer 200 of this example, an auxiliary spring member 60 is provided on the further outer peripheral portion of the joint rubber 90 to reinforce the hanging strength of the joint rubber 90. The auxiliary spring member 60 has one end in the expansion / contraction direction attached to the outer peripheral portion of the sink flange 51 (the holes 71a, 72a, 73a of the spring seats 71 to 73 of the sink base 53) and the other end to the hopper. 3 is attached to the outer peripheral portion (holes 74 a, 74 b, 74 c of the flange 74), and members below the hopper 3 are suspended from the sink flange 51. The auxiliary spring member 60 is composed of, for example, three tension springs 61 to 63.

  Furthermore, the hopper 3 and the sink flange 51 of this example are also provided with a pair of temporary holding engagement mechanisms 80 that are engaged when the disposer 200 is installed. One engagement mechanism 80 includes a metal fitting 81 on the sink flange side and a metal fitting 82 on the hopper side. The engagement mechanism 80 is disposed to have an engagement direction different from the expansion / contraction direction of the auxiliary spring member 60, and is normally disengaged.

  In addition, the separation angle between the attachment portions (hole portions 71a, 72a, 73a, hole portions 74a, 74b, 74c) of the tension springs 61 to 63 and the metal fittings 81 to 84 in this example is set in the same manner as in the first embodiment. (See FIG. 10).

  FIG. 15 is a top view illustrating an installation example of the disposer 200. When the disposer 200 is installed, the members below the hopper 3 are usually connected to the sink flange 51 attached to the kitchen sink S from the back side of the sink.

  First, the engaging mechanism 80 is engaged, and the hopper side is temporarily suspended on the sink flange side. At the same time, the pipe ends of the joint rubber 90 are fitted into the respective openings.

  In this temporary holding state, the auxiliary spring member 60, the hose bands 91 and 92, and the water pipe 43 are attached. In this example, the hose bands 91 and 92 are first loosely attached, and then the auxiliary spring member 60 (tensile springs 61 to 63) and the water distribution pipe 43 are sequentially attached.

  When attaching the water distribution pipe 43, the water distribution pipe 43 is firmly connected to the opening 42 a outside the water supply section 42 with a hose band (not shown). At this time, since the hopper side is temporarily held, the attaching operation can be performed with both hands.

  When the auxiliary spring member 60, the hose bands 91 and 92, and the water distribution pipe 43 are attached, the hopper side member is rotated to a normal relative rotation position as shown in FIG. At this time, the engagement of the engagement mechanism 80 is released, but the hopper side member is suspended by the joint rubber 90 and the auxiliary spring member 60. Therefore, the hopper side member can be held with both hands and rotated.

  Finally, the joint rubber 90 is firmly connected by the hose bands 91 and 92, so that the disposer 200 can be suspended and fixed to the kitchen sink.

  As described above, according to the disposer 200 as the third embodiment of the present invention, the engagement mechanism 80 for temporary holding is provided on the outer peripheral portions of the sink flange 51 and the hopper 3.

  With this configuration, the hopper side can be temporarily held on the sink flange side. Therefore, when connecting the sink flange 51 and the hopper 3, the operator can connect the hose bands 91 and 92, the auxiliary spring member 60, and the water distribution pipe 43 with both hands. It can be attached with. Accordingly, it is possible to improve work efficiency such as installation work of an automatic water supply type disposer. Moreover, the said operation | work can be done safely alone.
