The sound insulating plate 84 is provided with a cylindrical fitting portion 90, which is assembled to the shaft portion 82 in a state where the fitting portion 90 is fitted to the shaft portion 82. I have.

The fitting portion 90 has a predetermined height vertically, and the upper end thereof is in contact with the partition plate 70. Then, by the contact, a sound insulation portion 88 described later in the sound insulation plate 84 is formed.
A predetermined space is secured between the partition plate 70 and the water supply opening 86 of the partition plate 70. That is, in this example, the fitting portion 90 also functions as a spacer portion.

The shaft portion 82 is provided with a male screw portion 92 at the lower end thereof, and a nut 94 is screwed into the male screw portion 92 so that the sound insulating plate 84 is pressed against the partition plate 70 from below.

As shown in FIG. 6A, the partition plate 7
A pair of water supply openings 86 that penetrate the partition plate 70 are formed at positions 0 that are 180 degrees apart in the circumferential direction. Here, the water supply opening 86 has a long shape in the radial direction.

On the other hand, the sound insulation plate 84 is provided with the water supply openings 8.

A vertical engaging hole 96 is formed at the lower end of the safety lid 48, specifically at the lower end of the lower peripheral wall 74. This engagement hole 96 has an inwardly directed rib 98 as shown in FIGS. 7 (I) and 7 (B), and a switch 100 for operating the apparatus main body 22 (see FIG. 6 (B)). Specifically, by engaging the dish-shaped head 102 at the tip,
The switch 100 is turned on.

As clearly shown in FIGS. 7 (I) and 7 (A), a notch-shaped guide portion 104 is continuous with the engagement hole 96 at a portion adjacent to the engagement hole 96 in the circumferential direction. The guide portion 104 guides the switch 100 to the engagement hole 96 when the safety lid 48 is inserted downward into the insertion passage 66.

Next, the operation of the crusher 20 of this embodiment will be described. In the crushing apparatus 20 of this embodiment, first, food waste is introduced into the crushing chamber 50 of the apparatus main body 22 through the introduction passage 66 with the safety lid 48 removed. After that, the safety lid 48 is pushed into the insertion passage 66 and attached, so that the spoon and other articles in the sink 14 do not fall into the crushing chamber 50.

When the safety cover 48 is pushed in, the switch 100 is turned into the engagement hole 9 of the safety cover 48 as shown in FIG.
6 and is pulled, and the apparatus main body 22 is now in the operating state. That is, the rotating plate 56 is vigorously rotated by the motor 60, and the garbage in the crushing chamber 50 is finely crushed.

In this pulverization process, the water discharged from the sink faucet 18 is continuously supplied into the pulverization chamber 50 through the charging passage 66, and the garbage is pulverized under the water supply.

In the initial stage of the pulverization, the sink faucet 18
The water spouted from the container is temporarily stored in a container formed between the partition plate 70 of the safety lid 48 and the upper peripheral wall 72 and the inner surface of the charging passage 66. The water supply amount required at the time of pulverization is, for example, about 8 liters / minute, but when water is supplied at such a water amount, the size of the water supply opening 86 is previously selected so that the water supply is stored in the container portion. ing. When the water is collected in the container portion, the stored water forms a water sealing action, and the crushing sound from the crushing chamber 50 is prevented from leaking into the room through the charging passage 66 and the drain port 64 in a favorable manner.

Thereafter, when the pulverization is carried out violently, the amount of drainage from the pulverization chamber 50 is also increased,
At the same time, a force for strongly sucking the water stored in the container portion toward the pulverizing chamber 50 is applied. For this reason, the water stored in the container portion flows vigorously into the crushing chamber 50 side, and the stored water inside the container portion subsequently disappears. Therefore, at this point, the water sealing effect by the stored water, that is, the sound insulation effect of the crushing sound is also lost.

The water supply from the drain port 64 to the crushing chamber 50 is continued thereafter. Water supply at this time is a safety lid 48
Flows downward through the water supply opening 86 of the partitioning plate 70 at the time of the water supply opening 8 in the crushing device 20 of this embodiment.
Since the sound insulation portions 88 are provided at predetermined intervals below the 6, the flow resistance is given to water falling from the water supply opening 86. Therefore, the whole or most of the water supply opening 86 is sealed by the water flow, and the leakage of the crushing sound from the crushing chamber 50 is suppressed by the water sealing of the water supply opening 86 by the water flow.

As described above, in the garbage crushing apparatus 20 of the present embodiment, the sound insulating portion 88 of the sound insulating plate 84 gives the flow resistance to the water dropped from the water supply opening 86, and the flow resistance makes the whole water supply opening 86 uniform. Alternatively, most of it can be sealed with a water stream. Thereby, leakage of the crushing sound from the crushing chamber 50 can be effectively suppressed.

In the initial stage of pulverization when the suction force of water to the pulverizing chamber 50 does not work so strongly, the water collected in the container on the partition plate 70 provides a good sound shielding effect, and the pulverizing chamber 5
Prevent leakage of crushing noise from zero.

In this embodiment, a cylindrical anti-vibration joint 3 made of an elastic material is provided between the mounting flange 32 and the apparatus main body 22.
9, the device main body 22 is hung by the vibration isolating joint 39, and a lid receiving portion 126 is formed on the vibration isolating joint 39, and the safety lid 48 is formed by the lid receiving portion 126. Since the device is configured to receive and support, direct vibration transmission from the device main body 22 to the mounting flange 32 can be satisfactorily blocked at the vibration-proof joint 39, and the device main body 22 and the safety lid 48 The vibration transmission can be interrupted by the vibration isolating joint 39 between the two. Therefore, according to the present embodiment, the problem that the vibration of the apparatus main body 22 is transmitted to the mounting flange 32 and further to the sink 14 and the noise is generated by the vibration can be satisfactorily solved.

FIG. 8 shows another embodiment of the present invention. In this embodiment, the apparatus main body 22 and the cabinet 1 suspended by the mounting flange 32 via the vibration isolating joint 39 are shown.
6 and an elastic support 132 between the concrete floor 134 and the bottom plate 130, thereby elastically supporting the apparatus body 22. Thus, the vibration itself of the apparatus main body 22 is suppressed, and the vibration noise can be further reduced. Although the embodiment of the present invention has been described in detail, this is merely an example, and the present invention can be configured in variously modified forms without departing from the gist thereof.
