[0001]
BACKGROUND OF THE INVENTION
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.
[0002]
[Prior art]
Conventionally, a garbage input passage having a waste input port opened to a sink, a grinding chamber communicating with the input passage, and a lid fitted into the input passage from the dust input port, The garbage disposed in the pulverization chamber through the input passage is pulverized and discharged in the pulverization chamber, and the water flowing from the dust input port is covered with the lid body fitted into the input passage from the dust input port. 2. Description of the Related Art There is known a garbage pulverizer that is allowed to flow through a gap between an outer peripheral surface of a body and an inner peripheral surface of a charging passage.
[0003]
In this way, in the case of the garbage pulverizer of the type that pulverizes while supplying water to the pulverization chamber through the input path from the dust input port opened in the sink, the water supply to the pulverization chamber is provided even if the lid is attached to the trash input port. A route must be secured.
However, in the case of this garbage pulverizer, a large pulverization noise is generated when pulverizing garbage in the pulverization chamber, and this noise leaks into the room through the gap between the outer peripheral surface of the lid and the inner peripheral surface of the input passage. There was a problem of getting out.
[0004]
For example, Japanese Patent Application Laid-Open No. 2001-9313 is known as a garbage pulverizer that suppresses such pulverization noise.
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.
[0005]
[Problems to be solved by the invention]
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.
[0006]
The present invention has been made to solve the above-described problems. To the last, water flows down from the gap between the outer peripheral surface of the lid and the inner peripheral surface of the charging passage, and resists the flowing water. Is provided with a water seal in a gap that becomes a leakage portion of the pulverized sound, thereby insulating the sound, thereby providing a garbage pulverizing apparatus that can achieve reliable sound insulation while having a simple structure. It is said.

[0010]
The garbage pulverizing apparatus A of this embodiment is attached to the outer surface of the bottom surface of the sink 9 provided in the sink, and the trash that is connected to the input passage 1 of the garbage that has the trash input 10 opened in the sink, and is connected to the input passage 1. A chamber 2 and a lid 3 fitted into the introduction passage 1 from the dust introduction port 10 are provided.
[0011]
When using this garbage crushing apparatus A, garbage is introduced into the sink 9 from the garbage input port 10 and supplied to the crushing chamber 2 from the input passage 1. At this time, garbage may be thrown in from the garbage inlet while flowing water.
Thereafter, the lid 3 is fitted into the introduction passage 1 from the dust introduction port 10 while flowing water, and the water is passed through the gap S between the outer peripheral surface 31 of the lid 3 and the inner peripheral surface 11 of the introduction passage 1 in this state. The raw garbage is finely pulverized by the pulverization mechanism 20 provided in the pulverization chamber 2 while flowing down into the pulverization chamber 2.
The raw garbage crushed by the crushing mechanism 20 in the crushing chamber 2 is sent together with water to a solid-liquid separator (not shown), where it is separated into raw garbage and water, and the separated raw garbage is separated into a garbage tank (illustrated). (Omitted) and then dried by heating and drastically reduced. On the other hand, the separated water is drained into a water pipe (not shown).
[0012]
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 an outer peripheral surface 31 of the cylindrical body 30 on the inner periphery of the charging passage 1. Three ribs 34 projecting so as to be fitted into the locking grooves 12 formed on the surface 11 are formed at equal intervals (120 ° intervals), and the ribs 34 are fitted into the locking grooves 12. In such a state, the lid 3 is mounted in the charging passage 1 from the dust inlet 10 to position the lid 3 in the charging passage 1.
A magnet switch 35 serving as a power switch is built in one of the three ribs 34. The magnet switch 35 is installed in the charging passage 1 at the same time as the crushing chamber 1. The crushing mechanism 20 provided in 2 is operated.
Note that the power switch is not limited to the magnet switch 35, and for example, a mechanical switch or the like in which a switch button or a switch lever is pushed down by the attachment of the lid 3 can be used.
[0013]
A gap S between the outer peripheral surface 31 of the cylindrical body 30 and the inner peripheral surface 11 of the charging passage 1 is formed with a width sufficient to allow water necessary for pulverization to flow down into the pulverization chamber 2, and the rib 34 and On the outer peripheral surface 31 of the cylindrical body 30 between the ribs 34, a large number of streak-like protrusions 36 are formed at regular intervals so as to protrude opposite to the inner peripheral surface 11 of the charging passage 1. A streak groove 37 is formed between the protrusions 36 and 36.
In this case, the streak-like projecting portion 36 is formed so as to project from the bulging portion 38 formed on the outer peripheral surface 31 of the cylindrical body 30, and the tip end surface thereof is located substantially at the center (half) of the gap S. Is formed. The bulging portion 38 is not necessarily formed, and the line-like protruding portion 36 may be provided directly from the outer peripheral surface 31 of the cylindrical body 30.
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 31 of the lid 3, and the upper part of the outer circumference of the lid 3 above the line-like protrusions 36 The protrusion 36 and the streak-like groove 37 are formed on the flat peripheral surface 31a.
[0014]
As the streak-like protruding portion 36, as shown in the embodiment (FIGS. 1 and 2), 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. 5, it is formed in an oblique 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.
[0015]
Therefore, in the state where the lid 3 configured as described above is fitted into the charging passage 1, the gap S is narrowed by the line-like protrusions 36, so The protrusion 36 can provide resistance, and the flowing water can be temporarily retained upstream of the streaky protrusion 36 (in the sink 9 or the dust inlet 10).
In addition, 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. Therefore, the water flows down the gap S while the water is dispersed. Can be made.
[0016]
As a result, a water seal that closes the gap S is formed, and the flow of water to the pulverization chamber 2 is reduced while suppressing the pulverization sound at the time of pulverizing the garbage from leaking into the room from the garbage inlet 10. Can be secured.
[0017]
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 flowing in from the dust inlet 10 can be increased, and the water can be more reliably dispersed. A water seal can be formed.
Further, if the lid 3 is provided with the magnet switch 35, pulverization starts as soon as the lid 3 is mounted, and a water seal can be formed simultaneously with the start of the pulverization. .
[0018]
In addition, FIG. 6 is a test result comparing the noise level when using the lid body (silent lid) of the present invention in which the streak-like projections are formed and the lid body (standard lid) not having the streaky projections. As can be seen from this graph, the silent lid of the present invention was able to be reduced by about 10 decibels from the standard lid.
[0019]
【The invention's effect】
As described above, in the garbage crushing apparatus according to the present invention (Claim 1), a water seal is formed in the gap between the outer peripheral surface of the lid and the inner peripheral surface of the input passage, which is a leakage site of the crushing sound. Therefore, while the structure is simple, it is possible to ensure the flow of water necessary for pulverization and ensure sound insulation.
[0020]
In addition, if a flat peripheral surface is formed on the upper outer peripheral surface of the lid, the amount of water flowing in from the dust inlet can be increased, and a water seal that more reliably disperses the water is formed. be able to.
[0021]
If a power switch is provided on the lid (claim 2), a water seal can be formed simultaneously with the start of crushing, so that crushing noise can be suppressed from the beginning.
