Description

  The present invention relates to a garbage pulverizer, and more particularly to a technique for suppressing pulverization sound during pulverization processing from leaking into a room through a trash input.

  The garbage pulverizer includes a garbage input passage in which a garbage input port is opened in a sink, a crushing chamber communicated with the input passage, and a lid fitted into the input passage from the garbage input port, The raw garbage thrown into the pulverization chamber together with water through the input passage from the trash input is pulverized and discharged in the pulverization chamber. At the time of this pulverization process, the lid is fitted into the input passage from the trash input port. The water flowing in from the dust input port is caused to flow down to the pulverization chamber through a water passage between the outer peripheral surface of the lid and the inner peripheral surface of the input passage.

As described above, in the case of the garbage pulverizer of the type that performs pulverization while supplying water to the pulverization chamber through the input passage from the dust input port opened in the sink, the water passage is performed even when the lid is attached to the dust input port. A gap must be secured.
However, in the case of the garbage pulverizer, even when the garbage is pulverized in the pulverization chamber, a loud pulverization noise is generated. Even if the lid is attached to the trash input, this can be passed from the trash input to the room through the water passage. There was a problem of leaking.

2. Description of the Related Art Conventionally, a garbage pulverizer that suppresses such pulverization noise is known (see Patent Document 1).
The garbage pulverizer is formed in a shape that substantially closes the gap between the outer peripheral surface of the lid and the inner peripheral surface of the charging passage when the lid is mounted in the charging passage. A water supply opening is formed by providing a plate, while a sound insulation plate is provided on the lid, and the sound insulation plate provides resistance to the flow of water falling from the water supply opening, thereby sealing the water supply opening with water flow. ing.

However, in the conventional garbage crushing apparatus described above, in order to close the gap between the outer peripheral surface of the lid and the inner peripheral surface of the charging passage, a partition plate is provided on the lid to form a water supply opening, or a sound insulating plate The number of parts is increased and the structure becomes complicated.
In addition, since the gap between the outer peripheral surface of the lid and the inner peripheral surface of the input passage is closed, the attachment / detachment when the cover is fitted into the input passage from the dust input port becomes tight, and the attachment / detachment work is reduced. There is a problem that dirt cannot easily be attached to the sound insulation board because the sound insulation board cannot be used smoothly and water is received by the sound insulation board.
JP 2000-9313 A

  Note that the applicant of the present application has already proposed as a prior art a garbage crushing apparatus that suppresses crushing noise (Japanese Patent Application No. 2002-205675: Prior Art 1).

The garbage pulverizing apparatus of Prior Art 1 has a large number of streak-like protrusions formed on the outer peripheral surface of the lid body, and is located in the vicinity of the lower end of the lid body in a state of being fitted in the insertion path. A step portion is formed on the surface, and resistance is given to the flow of water by the streak-like protruding portion and the step portion, thereby forming a water seal in which the water passage gap is closed by water itself.
Therefore, according to the garbage pulverizing apparatus of Prior Art 1, the water passage gap is water-sealed, so that the pulverization noise can be suppressed while ensuring the water passage.

Further, in the applicant of the present application, the sink side receiving cylinder attached to the sink and the main body side receiving cylinder attached to the upper end opening of the pulverizer body via the displacement absorbing connecting cylinder are connected by a joint ring. And forming the inside of the sink side receiving cylinder and the main body side receiving cylinder as a garbage input passage leading to the crushing chamber of the pulverizer body, and the input from the dust input port of the sink side receiving cylinder A garbage pulverizer equipped with a lid fitted into the passage has already been proposed as a prior art (Japanese Patent Application No. 2003-322504: Prior Art 2).
In this prior art 2, it projects to the inner peripheral surface of the main body side receiving cylindrical body to form a right-angled stepped portion, and this right-angled stepped portion supports the lower end of the lid body fitted in the charging passage. It was.

Thus, in the structure in which the sink-side receiving cylinder and the main body-side receiving cylinder are separated, the lower end of the lid fitted into the charging passage from the dust inlet is connected to the inside of the main-side receiving cylinder. If it supports by the right-angle-shaped step part formed in the surrounding surface, if the plate | board thickness of a sink changes, the inflow width to a water flow gap will change.
As a result, there is a problem in that the amount of water flowing into the water passage gap is different from the design flow rate, an appropriate water seal cannot be formed, and the effect of suppressing crushing noise is reduced.
In addition, dust and dirt are likely to accumulate at the corners of the right-angled stepped portion, and there is a problem in terms of hygiene.

  The present invention has been made to solve the above-described problems. In the pulverization process, the water flowing in from the dust input port in the state where the lid is fitted into the input passage from the dust input port is passed through the gap. In the garbage pulverizer with a structure in which the sink side receiving cylinder and the main body receiving cylinder are separated from each other, even if the thickness of the sink changes, even if the sink thickness changes, It is an object of the present invention to provide a garbage pulverizer capable of effectively suppressing pulverization noise by supporting a lid so that the inflow amount of water can be maintained substantially constant and forming an appropriate water seal. .

In order to solve the above-mentioned problem, the garbage pulverizer of the present invention (Claim 1)
The sink side receiving cylinder attached to the sink and the main body side receiving cylinder attached to the upper end opening of the pulverizer body via the displacement absorption connecting cylinder are connected by a joint ring,
The inside of the sink side receiving cylinder and the main body side receiving cylinder is formed as a garbage input passage leading to the crushing chamber of the crusher body,
A garbage pulverizer comprising a lid adapted to be fitted into the input passage from the input port of the sink side receiving cylinder,
The raw garbage introduced into the pulverization chamber together with water through the input passage from the trash input port is pulverized and discharged in the pulverization chamber, and the lid is fitted into the input passage from the trash input port during the pulverization process. In the garbage pulverizer, the water flowing from the trash input port flows down to the pulverization chamber through a water passage gap between the outer peripheral surface of the lid and the inner peripheral surface of the input passage.
A tapered step is formed to project from the inner peripheral surface of the main body side receiving tube,
A vertical streak-like spacer is formed on the outer peripheral surface of the lid for holding the water passage gap between the outer peripheral surface of the lid and the inner peripheral surface of the charging passage. An inclined step is formed at the upper end of the
By supporting the inclined step portion of the vertical streak-like spacer with the mouth edge of the dust input port in a state where the lid is fitted into the input passage from the dust input port, the width of the inlet to the water flow gap Is formed to keep constant,
And it was set as the structure formed so that the lower end of a cover body might be located in the non-contact with respect to the said taper-shaped step part.

  Further, in the garbage pulverizing apparatus (Claim 1), a large number of line-like protrusions are formed on the outer peripheral surface of the lid body, and the lid body flows into the garbage inlet port while being fitted in the inlet passage. Water is passed through the water gap while giving resistance to the flow of the water flowing through the water gap, and the water seal is passed through the water seal with the water gap closed by the water flowing down the water gap. There is an aspect (Claim 2) that can be formed in the gap.

  In the present invention (Claim 1), in the pulverization process, the water flowing from the dust input port is caused to flow down to the pulverization chamber through the water gap with the lid fitted in the input passage, and the sink side In the garbage pulverizing apparatus having a structure in which the receiving tube body and the main body receiving tube body are separated, a lid that supports the inclined step portion of the vertical streak-like spacer formed on the cover body by the rim of the dust inlet Since it is formed in the body support structure, even if the thickness of the sink changes, the inlet width to the water passage gap can be kept constant, and the amount of water flowing into the water passage gap can be kept almost constant. It is possible to form an appropriate water seal and effectively suppress crushing noise.

In addition, the water flowing in from the dust input port flows down to the pulverization chamber through the water passage gap. At this time, resistance is also given to the flowing-down water by the tapered step portion formed in a tapered shape.
As described above, the tapered step portion is provided and the lower end of the lid is formed so as to be in the vicinity of the tapered step portion in a non-contact manner. A smooth flow can be secured, and an effective crushing process with a smooth flow of water can be performed at the same time as effective crushing noise suppression by the water seal.
In the above lid support structure, when the thickness of the sink changes, the distance between the lower end of the lid and the tapered step changes accordingly. In this case, the step is tapered. Since it is formed in a stepped portion, the amount of change can be reduced compared to the right-angled stepped portion of Prior Art 2, the change in flow resistance against flowing water can be reduced, and an appropriate water seal Can be formed.
Further, since the stepped portion is formed in a tapered stepped portion, it is possible to prevent dust and dirt from accumulating at the corner.

  Further, in the present invention (Claim 2), a large number of streak-shaped protrusions formed on the outer peripheral surface of the lid body provide resistance to the flow of water flowing in from the dust inlet so that the water passage gap is provided. Since it is the structure which forms a water seal and is sound-insulated, a water seal can be formed reliably and the suppression of a pulverization sound more reliably can be performed.

Hereinafter, embodiments of the present invention will be described with reference to the examples shown in the drawings.
FIG. 1 is a longitudinal sectional view showing a main part of the garbage crushing apparatus of the embodiment, and FIGS. 2 and 3 are cross-sectional views showing the main part of the garbage crushing apparatus. 4 and 5 are side views showing other examples of the lid.

  The garbage pulverizer includes a sink-side receiving cylinder 2 attached to the sink 1, a body-side receiving cylinder 4 attached to the upper end opening 90 of the crusher body 9, and the sink-side receiving cylinder 2. And a joint ring 5 for connecting the main body side receiving tube 4.

The sink-side receiving cylinder 2 has a dust inlet 20 opened on the upper surface and an outer peripheral flange 21 formed on the upper end.
The sink-side receiving tube 2 is fitted into a mounting hole 10 formed in the sink 1 from above, and an inner peripheral edge portion 11 of the mounting hole 10 is connected to the outer peripheral flange 21 and an inner ring of a joint ring 5 described later. 50, the mounting structure is sandwiched between the packings 23, 23.

The main body side receiving cylinder 4 is attached to the upper end opening 90 of the pulverizer main body 9 via an elastic cylinder 6 as a displacement absorbing connecting cylinder, and a tapered step 42 projects from the inner peripheral surface thereof. Is formed.
In this case, the lower end portion of the elastic cylinder 6 is fixed to the upper end opening 90 of the pulverizer body 9 by the retaining ring 60, and the outer peripheral surface of the main body side receiving cylinder 4 is attached to the inner peripheral surface of the elastic cylinder 6. It has a mounting structure that is fitted with uneven parts.
The displacement absorbing connecting cylinder is for preventing vibration generated from the crusher main body 9 from being transmitted to the sink, and is not necessarily elastic, but a bellows tube or a flexible tube. Can be used.

  The insides of the sink-side receiving cylinder 2 and the main-side receiving cylinder 4 are formed as a garbage input passage T that reaches the pulverization chamber (not shown) of the pulverizer body 9. The lid 3 is fitted from the dust inlet 20 of the sink side receiving cylinder 2.

The pulverizer body 9 pulverizes and discharges the garbage that has been introduced into the pulverization chamber together with water from the dust input port 20 through the input passage T, and discharges the lid 3 from the dust input port 20 to the input passage T. In the fitted state, the water flowing in from the dust inlet 20 is allowed to flow down through the water passage gap S between the outer peripheral surface of the lid 3 and the inner peripheral surface of the input passage.
The garbage that has been crushed in the crushing chamber is sent to a solid-liquid separator (not shown) together with water, where it is separated into garbage and water, and the separated garbage is collected in a garbage tank (not shown). The amount of water is reduced by heating and drying, while the separated water is drained to a water distribution pipe (not shown).

  The joint ring 5 is for connecting the sink side receiving cylinder 2 and the main body receiving cylinder 4, and includes an inner ring 50, an outer ring 51, and a lock piece 52.

The inner ring 50 is formed such that the upper end portion is screwed to the sink side receiving tube 2 from the lower end and the lower end portion is fitted to the main body side receiving tube 4 from the upper end.
In this case, the inner ring 50 is formed by sandwiching the inner peripheral edge portion 11 of the mounting hole 10 of the sink 1 between the upper end of the inner ring 50 and the outer peripheral flange 21 of the sink-side receiving cylinder 2. The sink side receiving tube 2 is screwed to the sink side receiving tube 2 so that the sink side receiving tube 2 is attached thereto.

The outer ring 51 is rotatably provided on the outer periphery of the inner ring 50, and a cam surface 54 is formed on the inner peripheral surface thereof.
The cam surface 54 is formed at equal intervals at four locations on the inner peripheral surface of the outer ring 51, and the shallow groove portion 55 having a shallow depth from the inner peripheral surface of the outer ring 51, and the inner peripheral surface of the outer ring 51. The deep groove portion 56 has a deep depth, and the inclined groove portion 57 that makes the shallow groove portion 55 and the deep groove portion 56 continuous is formed.
In addition, the outer peripheral surface of the outer ring 51 is formed in a polygonal surface so as to serve as a finger when the outer ring 51 is turned by hand.
Further, it is sufficient that the cam surface 54 has a plurality of locations (three or more locations), and it is not always necessary to form them at regular intervals.

The lock piece 52 is fitted in a through hole 58 formed in the inner ring 50 so as to face the cam surface 54, and is provided so as to be able to advance and retract in the radial direction of the inner ring 50. A head 59 for preventing dropout is formed.
Therefore, when the upper end portion of the main body side receiving cylinder 4 is fitted to the lower end portion of the inner ring 50, the outer ring 51 is connected to the deep groove portion 56 of the cam surface 54 as shown in FIG. , The tip of the lock piece 52 is retracted into the through hole 58, and the lock piece 52 obstructs the fitting between the inner ring 50 and the main body side receiving cylinder 4. There is nothing.
Then, from this state, as shown in FIG. 3, if the outer ring 51 is rotated to a position where the shallow groove portion 55 of the cam surface 54 faces the lock piece 52, the lock piece 52 is moved to the head 59 by the shallow groove portion 55. Is pushed, the tip of the lock piece 52 advances from the through hole 58 and engages with a locking groove 41 formed on the outer peripheral surface of the main body side receiving cylinder 4, and the inner ring 50 and the main body side receiving cylinder 4 are engaged. The fitting state can be fixed.

The outer ring 51 needs to be fixed at a position where the lock piece 52 is pushed in by the shallow groove portion 55.
In this case, as shown in FIG. 4, a flat support portion 50a is formed on the outer periphery of the inner ring 50, and the front end surface of the stopper member 5a is applied to the flat support portion 50a. The protrusion 5b formed on the outer ring 51 is fitted into a groove 5c formed above and below the flat portion 50a, and the rear end surface of the stopper member 5a is screwed to a stopper plate 5d screwed to the outer peripheral surface of the outer ring 51. Thus, the outer ring 51 and the inner ring 50 are fixed via the stopper member 5a.

  The stopper member 5a is provided with an outlet. In this case, when the lid 3 to be described later is fitted into the garbage input port 20 when the garbage is pulverized, the reed switch 5e incorporated in the stopper member 5a is activated in response to the magnet provided on the lid 3, and pulverized. The machine starts moving and crushes trash.

Next, the configuration of the lid 3 will be described.
The lid 3 has a flange 32 formed at the upper end of the cylindrical body 30, a handle 33 projecting from the upper surface of the flange 32, and the cylindrical body 30 has an outer peripheral surface and an input passage on the outer peripheral surface. A plurality of (three in the embodiment) vertical streak-like spacers 34 for holding the water flow gap S between the inner peripheral surface of T are formed at equal intervals (120 ° in the embodiment). Yes.
An inclined step portion 31 is formed at the upper end portion of the vertical streak-like spacer 34.

The water passage gap S between the outer peripheral surface of the cylindrical body 30 and the inner peripheral surface of the charging passage T is formed with a width sufficient to allow water necessary for pulverization to flow down to the pulverization chamber, and On the outer peripheral surface of the cylindrical body 30 between the vertical streak-like spacer 34 and the vertical streak-like spacer 34, a large number of streak-like protrusions 36 are formed at regular intervals. A streak groove 37 is formed between them.
In this case, the streak-like projecting portion 36 is formed so as to project from the outer peripheral surface of the cylindrical body 30, and the tip end surface thereof is formed so as to be located at substantially the center (half) of the water passage gap S.
Further, the large number of the line-like protrusions 36 are formed from the middle in the vertical direction to the lower end of the outer peripheral surface of the lid 3, and the upper part of the outer peripheral surface of the lid 3 above the line-like protrusions 36 is a line-like protrusion. The part 36 and the streak-like groove 37 are formed on the flat peripheral surface 31a.

  As the streak-like protruding portion 36, as shown in the embodiment (FIGS. 5 and 6), it is formed in a longitudinal streak shape extending in a direction parallel to the axial direction of the cylindrical body 30, as shown in FIG. As shown in FIG. 8, it is formed in a diagonal line extending in an oblique direction with respect to the axial direction of the cylindrical body 30, as shown in FIG. There is something formed.

  The support structure of the lid 3 is such that the inclined step portion 31 of the vertical streak-like spacer 34 is connected to the dust inlet 20 in a state where the lid 3 is fitted into the inlet passage T from the dust inlet 20. By supporting by the lip 20a, the width of the inlet S1 to the water flow gap S is formed to be kept constant, and the lower end of the lid 3 is not in contact with the tapered step portion 42 in the vicinity. It is formed to be located.

When using this garbage crushing apparatus, garbage is introduced from the garbage input port 20 while flowing water through the sink 1 and is supplied from the input passage T to the crushing chamber.
Thereafter, the lid 3 is fitted into the introduction passage T from the dust introduction port 20 while flowing water, and the water passage gap between the outer peripheral surface of the lid 3 and the inner peripheral surface of the introduction passage T in this state. While letting water flow down to the crushing chamber through S, the garbage is finely crushed by a crushing mechanism provided in the crushing chamber.

  In a state where the lid 3 configured as described above is fitted into the charging passage T from the dust inlet 20, the inclined step portion 31 of the vertical streak-like spacer 34 formed in the lid 3 is the rim of the dust inlet 20. Since it is supported by 20a, the width of the inlet S1 to the water flow gap S is kept constant even when the thickness of the sink 1 to which the garbage crusher is attached varies from construction site to construction site. The amount of water flowing into the water flow gap S can be kept constant, and an appropriate water seal can be formed to effectively suppress crushing noise.

In addition, the water flowing in from the dust inlet 20 flows down to the pulverization chamber through the water passage gap S. At this time, the inside of the inlet passage T is positioned so as not to contact the lower end of the lid 3 in the vicinity. Since a tapered step 42 is formed on the peripheral surface (the inner peripheral surface of the main body-side receiving cylinder 4), resistance is given to the flowing water by the tapered step 42.
In this way, the tapered step 42 is provided, and the lower end of the lid 3 is formed so as to be located in the vicinity of the tapered step 42 in a non-contact manner, so that resistance is given to the flowing water. The smooth flow of water can be ensured by the taper, and the effective pulverization process with the smooth flow of water by the taper can be performed simultaneously with the suppression of the effective pulverization sound by the water seal.

Further, in the lid support structure in which the lid 3 is supported by the rim 20a of the dust inlet 20, if the thickness of the sink 1 changes, the distance between the lower end of the lid 3 and the tapered step portion 42 is accordingly changed. However, in this case, since the stepped portion is formed in the tapered stepped portion 42, the amount of change can be reduced compared to the right-angled stepped portion.
For example, as shown in FIG. 9, in the case of the right-angled stepped portion 7, the thickness of the sink 1 is increased, and the height of the lower end of the lid 3 is increased from the position X1 indicated by the broken line to the position X2 indicated by the solid line. When rising by Z, the distance between the lower end of the lid 3 and the right-angled stepped portion 7 increases from x1 to x2, and the change amount x increases.
Further, as shown in FIG. 10, in the case of the tapered step 42, the thickness of the sink 1 is increased, and the lower end of the lid 3 is moved from the position Y1 indicated by the broken line to the position Y2 indicated by the solid line, as shown in FIG. The distance between the lower end of the lid 3 and the tapered step portion 42 increases from y1 to y2, and only the change amount y increases.
Thus, when formed in the tapered step 42, the amount of change can be reduced compared to the right-angled step 7 (x> y), thereby reducing the change in the flow resistance against the flowing water, An appropriate water seal can be formed.
Further, since the stepped portion is formed in the tapered stepped portion 42, it is possible to make it difficult for dust and dirt to collect in the corner portion.

Further, in the state where the lid 3 is fitted from the dust inlet 20 into the inlet passage T, the water passage gap S is narrowed by the streak-like projecting portion 36, so that the flow of water flowing from the dust inlet 20 is reduced. The streak-like projecting portion 36 gives resistance, and the water flowing down can be temporarily retained on the upstream side (in the sink 9 or the dust inlet 20) from the streaky projecting portion 36.
Then, the water is dispersed by this stay, and the water flows using a large number of streak grooves 37 formed between the streak protrusions 36 and 36 as a guide. Can flow down.

  As a result, a water seal that closes the water passage gap S is formed, and the flow of water to the pulverization chamber is suppressed while preventing the pulverization sound at the time of pulverizing the garbage from leaking into the room from the garbage inlet 20. Can be secured.

  Further, as described above, if the flat peripheral surface 31a is formed at the upper part of the outer peripheral surface of the lid 3, the amount of water that flows in from the dust inlet 20 can be increased, and the water can be more reliably dispersed. A water seal can be formed.

In the embodiment, the sink side receiving cylinder 2 and the inner ring 50 of the joint ring 5 are connected by screwing, and the main body receiving cylinder 4 and the inner ring 50 are connected by the lock piece 52. However, on the contrary, the present invention is also applied to a case where the sink side receiving cylinder and the inner ring are connected by a lock piece, and the main body side receiving cylinder and the inner ring are connected by screwing. Applicable.
Also, the connection between the sink-side receiving cylinder and the inner ring and the connection between the main-body receiving cylinder and the inner ring can be connected together by a locking piece, and the sink-side receiving cylinder and the joint ring can be screwed together. The present invention can also be applied to those in which the main body side receiving tube and the joint ring are connected by screwing together.

Further, in the garbage pulverizing apparatus of the present invention, the vibration isolating means may be assembled in advance to the pulverizer body.
As the vibration isolating means, a support member is attached to the main body side receiving cylinder from above the displacement absorption connecting cylinder (for example, an elastic cylinder), and a vibration absorbing elastic body is interposed between the support member and the pulverizer body. The anti-vibration structure can be made.
