Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mounted under a sink drain of a sink installed in a kitchen, and is attached to a garbage throwing port of a disposer for crushing food waste such as vegetables and fish. The present invention relates to a splash guard for disposers that prevents crushed garbage from jumping out.

[0002]

2. Description of the Related Art A disposer is installed under a sink in a kitchen, and disposes of garbage such as kitchen waste discharged from the sink with water (drain may be used) while crushing it finely and discharging it to drain pipes and drains. This is a facility for crushing food waste with a rotating blade and a fixed blade that rotate at high speed in a cylindrical crushing chamber. The above-mentioned disposer supplies water into the processing chamber and continuously feeds raw garbage into the operating disposer, and the continuous type in which raw garbage is thrown into the stopped disposer and water is fed into the grinding chamber. It is classified into a batch system in which a lid is opened, water is supplied and crushed, and a fixed amount is treated.

[0003]

However, in the conventional disposer, the continuous type and the batch type crush the water while supplying water to the crushing chamber. Therefore, during the crushing, noise such as crushing noise and draining noise is used through the opening. Reach the person and cause discomfort. In particular, the continuous type produces a loud noise because it cannot be covered. Further, a splash guard is provided in the path between the charging port and the crushing chamber in order to prevent the crushed material from jumping out from the charging port, and noise is somewhat reduced by forming a water film at the splash guard opening by water supply. However, if the amount of water supply is small, or if the water supply position on the sink is far from the garbage input port, sound is likely to leak because the water film formation is not stable. Although it is possible to reliably form a water film in the opening and reduce noise by supplying a large amount of water, it is uneconomical to supply water in excess of the water supply amount necessary for crushing and transportation.

As a means for solving the above problem, for example, Japanese Patent Laid-Open No. 11-244723 discloses a method of installing a soundproofing device at a charging port. However, in the present invention, since the water storage container and the sound insulation cylinder are used for soundproofing, the apparatus becomes complicated, the cost increases and the maintenance frequency also increases, and it is not realistic to adopt the disposer. The present invention has been made in view of the above problems, and an object thereof is to provide a splash guard for a disposer, which has a simple structure and can reduce noise generated from the disposer.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic vertical cross-sectional view showing the entire disposer to which a disposer splash guard 8 of the present invention (hereinafter, simply referred to as a splash guard) is attached. This disposer basically comprises a casing 1 having a cylindrical shape with a bottom, and a crusher 2 for garbage, and a crushing chamber 3 for garbage is provided in an upper part of the casing 1 so that A discharge chamber 4 for crushed raw garbage is provided in the lower part, and a crusher 2 is provided at the boundary between the crush chamber 3 and the discharge chamber 4 in the casing 1.
Is provided. At the upper end of the casing 1, the grinding chamber 3
A tray 13 is provided at an inlet 11 for feeding raw garbage into the sink, and the inlet 11 is connected to the inner bottom of the sink by a connecting member 5.
The garbage can be put into the crushing chamber 3 from the inside of the sink by connecting the trash. A splash guard 8 is attached to the inside of the connecting member 5, and an inner peripheral surface thereof has a convex shape so that the splash guard 8 can be fixed. In addition, a discharge port 4 for discharging raw garbage crushed in the crushing chamber 3 to the discharge chamber 4 is provided in the lower portion of the outer peripheral wall of the casing 1.
1 is provided, and a discharge pipe 6 extending to a waste water treatment device (not shown) is connected to the discharge port 41 thereof.

On the other hand, the crusher 2 has a disk-shaped turntable 21, a pair of swing hammers 22 pivotally supported on the upper surface of the turntable 21, and a casing 1.
And an annular fixed tooth 23 provided on the inner peripheral surface of the turntable 21 facing the outer peripheral surface of the turntable 21. The rotation of the turntable 21 fixes the garbage thrown on the turntable 21 mainly to the swing hammer 22. Tooth 23
It can be crushed by. The turntable 21 of the crusher 2 described above is fixed to the drive shaft 25 of the motor 24 assembled in the lower portion of the casing 1, and can be rotated by driving the motor 24. In the case of the continuous type, the motor 24 is driven by an operation switch installed outside, and in the case of the batch type, when the metal detector 7 attached to the outer periphery of the connecting member 5 detects the attachment of the eye plate 13, Automatically drive and crush. Incidentally, reference numeral 12 in the figure denotes a water shut lid.

FIG. 2 is a schematic vertical sectional view of the splash guard 8 and shows an example of the present invention. Figure 3
Is a top plan view thereof. As described above, this splash guard is mounted in the connecting member 5 of the disposer shown in FIG. As shown in FIGS. 2 and 3, the splash guard inner wall 8a has a bowl shape,
The bottom 8b has a flat shape. In addition, weirs 8d having openings 8c at equal intervals are provided along the circumferential direction of the upper end surface of the splash guard 8.

The height of the weir 8d is preferably 2 to 10 mm. If this height is less than 2 mm, the water does not flow evenly, and if it is 10 mm or more, the resistance of the water supply increases. The width of the opening 8c is preferably 2 to 15 mm. If the width of the opening 8c is less than 2 mm, the water flows unevenly, and if it exceeds 15 mm, the amount of water flowing from the opening near the water supply position increases. It is preferable that the number of openings 8c is 2 to 10 at equal intervals.
If the number of openings 8c is less than 2 or exceeds 10,
Water does not flow evenly.

A method of crushing raw garbage with a disposer using the above splash guard will be described again with reference to FIG. In the case of the continuous type, water was supplied into the disposer in which the splash guard 8 was set (water supply amount 8 L / min), and the disposer was operated. Then, with the disposer activated, garbage was put in through the inlet 11. In the case of the batch type, the eye plate 13 was removed, and a certain amount of raw garbage was introduced into the disposer in which the splash guard 8 was set through the inlet 11, and then water was supplied (water supply amount 8 L / min). Next, by closing the charging port 11 with the eye plate 13, the metal detector detects and the crushing is automatically started. At that time, the inner wall of the splash guard 8 has a bowl shape and a flat shape toward the bottom, and by providing weirs having openings at equal intervals along the circumferential direction of the upper end surface, water is supplied to the inlet port. Even if it flows in from the direction, it flows down evenly on the splash guard, so that the water film can be formed faster and more reliably, and noise is reduced.

FIG. 4 shows the results of measuring the noise when crushing raw garbage when using the splash guard of the present invention and when using a splash guard having a straight running water portion and no weir. From Fig. 4, the noise level is about 10
It was found that the sound pressure at each frequency was reduced by reducing the dB.
