Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a garbage crusher used in a kitchen or the like.

[0002]

[Prior art]

 Raw garbage from kitchens such as homes is often stored in a corner of a sink before it is thrown into a garbage bucket, but recently, the method of throwing it away from the drain of the sink is a crusher (disposer). Is increasing due to the spread of.

This crusher has a mechanism in which a crushing tooth for crushing raw garbage is rotated by a motor. This crusher is attached to the drainage port of the sink to crush the garbage that enters from the drainage port and let it flow with water.

Now, this crusher emits a rotating sound of a motor and the like and a crushing sound of crushing raw garbage during use. The rotating sound is emitted as a continuous sound during use, and the crushing sound when garbage is added overlaps with this and becomes noise.

Generally, a crusher is hidden in a sink and is attached to the sink so that it is more or less sound-proof. Regarding the other crushing sound, the raw trash input port of the crusher is looking out from the drain port, and every time a person inputs garbage, the crushing sound leaks directly from the drain port in front of me. Come on.

On the other hand, due to recent advances in sound deadening technology, various attempts have been made to reduce the noise of the crusher, for example, the proposal in JP-A-55-5746. As described above, the conventional technique for the noise of the crusher was a technique for reducing the noise.

[0007]

[Problems to be Solved by the Invention] However, even if the noise of the crusher is reduced in this way, there is a limit, and the rotation noise and the crushing noise are still noises in daily life. In particular, since the crushing device has an input port for garbage, the sound source of the crushing noise cannot be sealed, and the volume is generally higher than the rotating sound. In addition, the smashing sound is not only loud in volume, but it is also a sound that smashes garbage, which causes a problem of making people feel unclean and uncomfortable.

Therefore, it is necessary to continue improving the technique for reducing these sounds as much as possible, but on the other hand, on the assumption that these noises are not completely eliminated, they are accepted as sounds that are not annoying as much as possible. However, another noise countermeasure will be needed.

The present invention has been devised in view of such circumstances, and its purpose is to make the rotation sound feel smaller due to the characteristics of the ear, and the crushing sound is the sound of garbage. It is an object of the present invention to provide a garbage crusher capable of removing uncleanness and discomfort.

[0010]

[Means for Solving the Problems]

 The present invention provides, as a means for solving the above-mentioned problems, "a garbage crusher having a melody device for generating and eliminating a melody in synchronization with the start and stop of the crushing teeth of the garbage crusher. Is the content.

[0011]

[Action]

 By adopting the above-mentioned means in the present invention, the melody sounds while the crusher is in use, and the user does not feel uncomfortable due to the crushing sound or the like. This is because the present invention makes effective use of how the human ear feels and illusions. In the present invention, it is possible to eliminate the discomfort by selecting the melody emitted from the melody device of the above means and adjusting the volume and sound quality of the melody according to the characteristics of the human ear.

That is, to explain this with reference to FIG. 4, the rotating sound 61 is rather smooth in the middle frequency range, and is a constant sound with no change in intensity or pitch. It has been empirically known that when a melody sound 50 louder than the rotation sound 61 and having a high and low strength and a high and low sound is overlaid, the human ear picks up only this melody sound 50. That is, although the actual rotation sound 61 is conventionally heard in the ear, it cannot be heard by the human sense.

In addition, even with the rotating sound, a startling sound 62 with a pronounced groan is emitted particularly at the time of starting, but at the same time, the melody sound 50 also starts to sound. Although this melody sound 50 always has the same volume, it feels loudest to the ear at the beginning of the melody sound, and as a result, it has the effect of canceling the start-up sound 62 of rotation.

On the other hand, the shattering sound 63 is synthesized or drowned out with the melody sound 50, and sounds like noise mixed in the melody. Of course, the melody sound 50 is not the original clear sound, but at least it is difficult for people nearby to recognize it as the sound of garbage, and the unpleasant sensation is greatly reduced.

[0015]

【Example】

 Next, an embodiment of the crusher according to the present invention will be described with reference to FIGS. The inside of the main body of the crusher 100 in this embodiment is divided into a machine room A in which the crushing device 10 is housed and an electric room B in which the melody device 20 is housed.

The electric chamber A is provided at the bottom of the crusher 100, and the bottom of the bottom is a removable bottom cover C. The melody device 20 has a melody IC 21 and a speaker 23 as main components. The switch 30 of the crusher 100 is provided at a position (not shown) around the sink so that the user can easily operate it, thereby synchronizing the start and stop of the melody device 20 and the crusher 10. .

Therefore, when the switch 30 is turned on, the melody device 20 as well as the crushing device 10 is powered on, whereby the melody emitted from the melody IC 21 starts to sound through the speaker 22. The speaker 22 is attached to the inside of the bottom pig C so that the speaker 22 faces downward, and the part of the bottom pig has a slatted shape, and a window is provided for emitting the melody to the outside.

Now, when the user switches on the crusher 100 configured as described above, the crushing device 10 and the melody device 20 are simultaneously started. In other words, the rotating sound 61 and the melody sound 50 are emitted at the same time, but the user especially hears the melody sound 50. Next, when you throw in the garbage, you will hear a sound like noise mixed in the melody. Actually, this is the shattering sound 63.

Although the user sometimes puts in the garbage all at once, it is often the case that he puts out the garbage that comes out halfway through the cooking into a small amount, and it is troublesome to turn the switch 30 on and off each time. . In such a case, it is desirable to keep the switch 30 turned on while cooking, but the sound of the conventional crusher 100 for a long time is a concern, and the melody of this embodiment is a concern. I won't.

Since the speaker 22 is attached integrally with the crusher 100 and faces downward, it is omnidirectional with respect to the horizontal direction, and even if the user moves around in kitchen work, it is uniform regardless of the standing position. In addition, the noise countermeasure effect of the present invention can be obtained.

Since the omnidirectionality described above does not impose any restrictions on the installation direction of the crusher 100, and because the crusher 100 is integrated, the installation work is the same as in the past and no burden is imposed. No increase. Further, since the speaker 22 is on the inside of the bottom surface, even if water is splashed for some reason, the speaker itself is hard to get wet and is safe. Further, the melody device 20 is also provided with its own switch 23, and if it is turned off in advance, the melody does not sound even while the crushing device 10 is operating, which is an abnormality due to, for example, a hearing check of the rotating sound 61. Useful for checking the presence or absence of

[0022]

[Effect of device]

 As described above, according to the present invention, by the above means, it is possible to obtain the effect that the rotation sound is hardly discerned by the melody sound and the shattering sound is changed to the extent that a strange sound is mixed in the melody. The effect of not giving discomfort to the person is obtained.
