DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer which is attached to a drain of a home sink to crush food garbage. In particular, the present invention relates to improvements for effectively pulverizing garbage.

[0002]

2. Description of the Related Art Conventionally, a general household disposer is configured to throw garbage into a crushing chamber from a garbage input port of a disposer body connected to a sink drain, and to provide a turntable disposed in the crushing chamber. The garbage is crushed and discharged by rotating the table. Specifically, for example, as disclosed in Japanese Patent Application Laid-Open No. 12-51729, fixed teeth are provided on the outer peripheral side of the turntable, and a pulverizing hammer is mounted on the turntable. Grind the garbage between the fixed teeth and the grinding hammer by rotating. And the garbage after this pulverization falls from the gap between the fixed teeth and the turntable,
It is discharged to the discharge pipe with running water.

[0003]

Incidentally, in this type of disposer, it is required to pulverize as much as possible in order to prevent the discharged garbage from being clogged in the piping. As a means to meet this requirement,
It is conceivable to set the gap between the crushing hammer and the fixed teeth as small as possible, or to set the driving time of the disposer longer.

[0004] As described above, when the gap between the grinding hammer and the fixed teeth is set small, it becomes possible to finely pulverize the garbage inserted between the two. However, this configuration makes it difficult for relatively large garbage (eg, bird bones) to enter between the crushing hammer and the fixed teeth, and causes a problem that such garbage remains in the disposer and cannot be crushed. there is a possibility.

On the other hand, if the garbage is pulverized by setting the drive time of the disposer to be longer, power consumption is increased due to the extension of the drive time, which is not practical. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a disposer capable of reliably pulverizing garbage of various sizes without requiring a long drive time. Is to do.

[0007]

Means for Solving the Problems-Summary of the Invention-In order to achieve the above object, the present invention provides a finer garbage crushed by this crushing mechanism in addition to a conventional garbage crushing mechanism. A means for crushing is provided.

-Solution Means- A first solution means is provided with crushing teeth provided on an upper surface of a turntable, and fixed teeth provided on an outer peripheral side of the turntable. Accordingly, a disposer for crushing garbage between crushed teeth and fixed teeth is assumed. The disposer is provided with second crushing teeth on the lower surface of the turntable for further crushing crushed garbage falling from a gap between the fixed teeth and the turntable.

According to this particular matter, first, garbage is crushed between the crushing teeth and the fixed teeth with the rotation of the turntable. Thereafter, the crushed garbage is crushed by the second crushing teeth when falling from the gap between the fixed teeth and the turntable, and thereby becomes a finely crushed state. For this reason, it is possible to finely pulverize garbage without having to set a small gap between the crushing teeth and the fixed teeth or to set a longer driving time of the disposer.

The second solution specifically specifies the configuration of the second crushed teeth. That is, in the first solving means, the second crushing teeth are rotatably and integrally attached to the lower surface of the turntable, and the outer ends of the second crushing teeth are projected outside the outer peripheral edge of the turntable. I have.

According to this specific matter, the second crushing teeth can be rotated by using the rotation drive source of the turntable, and the fine crushing operation can be performed efficiently. Further, since the outer end of the second crushing teeth faces the gap between the turntable and the fixed teeth, it is possible to crush the garbage falling through this gap without fail.

A third solution relates to another means for finely pulverizing garbage. In other words, it is assumed that a disposer performs crushing processing of garbage introduced into the crushing chamber by a crushing mechanism. In this disposer, a pulverizing mechanism comprising a plurality of pulverizing units each including a pulverizing tooth provided on an upper surface of a turntable and a fixed tooth provided on an outer peripheral side of the turntable is configured. Then, the garbage is crushed between the crushing teeth and the fixed teeth with the rotation of the turntable in each crushing section, and the crushed garbage is sequentially supplied from the crushing section on the front side to the crushing section on the rear side. I have.

According to this specific matter, the garbage is gradually pulverized by a plurality of pulverizing operations by each pulverizing section. For this reason, according to this configuration, it is also possible to finely pulverize garbage without having to set a small gap between the crushing teeth and the fixed teeth or to set a longer driving time of the disposer.

The fourth and fifth solving means specifically specify the difference in the configuration between the former-stage pulverizing section and the latter-stage pulverizing section. That is, in the fourth solution, in the third solution, each crushing unit is configured to drop crushed garbage to a downstream side from a gap between the turntable and the fixed teeth. The gap between the turntable and the fixed teeth in the crushing section is set smaller than the gap between the turntable and the fixed teeth in the preceding crushing section. According to a fifth aspect of the present invention, in the third or the fourth aspect, the number of fixed teeth in the crushing section on the subsequent stage is
The number is set to be larger than the number of fixed teeth in the crushing section on the front stage side.

According to these specific items, it becomes possible to reliably pulverize the raw garbage coarsely pulverized in the first-stage pulverizing section in the second-stage pulverizing section, and to efficiently reduce the load in each of the pulverizing sections. Fine grinding operation can be realized.

As described above, according to the present invention, the following effects are exhibited.

According to the first and second aspects of the present invention, the second crushing teeth for further crushing the crushed garbage falling from the gap between the fixed teeth and the turntable are provided to finely crush the garbage. ing. In other words, fine crushing of garbage is not performed by setting the gap between the crushing teeth and the fixed teeth to be small or setting the driving time of the disposer to be long. Therefore, even large-sized garbage can be satisfactorily penetrated between the crushing teeth and the fixed teeth to perform crushing, and does not cause an increase in power consumption. As a result, it is possible to provide a disposer that can surely pulverize garbage of various sizes without requiring a long drive time, and can reliably avoid clogging of the discharge pipe. In addition, since the outer end of the second crushing teeth is projected outside the outer peripheral edge of the turntable, garbage falling through the gap between the turntable and the fixed teeth can be crushed reliably, and fine crushing can be performed. The reliability of the function can be improved.

According to the third aspect of the present invention, the garbage is gradually pulverized by a pulverizing operation of a plurality of pulverizing units. This also makes it possible to provide a disposer that can surely pulverize garbage of various sizes without requiring a long drive time and can reliably avoid clogging of the discharge pipe.

Further, the invention according to claims 4 and 5 employs a configuration in which the fine pulverizing performance of the subsequent-stage pulverizing section is improved as compared with the preceding-stage pulverizing section. For this reason, it is possible to reliably pulverize garbage, and it is possible to realize an efficient pulverizing operation while appropriately suppressing the load on each pulverizing unit.
