Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposer for crushing garbage such as vegetable scraps and fish bones, and more particularly to a disposer suitable for crushing lumpy garbage such as relatively large root vegetables and fish heads.

[0002]

2. Description of the Related Art Conventionally, among the disposers for crushing garbage such as vegetable scraps and fish bones, there has been disclosed a disposer having a structure shown in FIGS. 1 and 2 as an efficient crusher for garbage of different sizes. (Japanese Patent Laid-Open No. 55-3877). That is, 1 is an upper casing, and a charging port 1 is provided above.
4, a water supply port 15 on the side, and a crushing chamber 12 on the lower side.
Is provided. Reference numeral 3 denotes a lower casing having a discharge port 13, a drive motor 11 is connected to the lower portion, and a rotary shaft 10 inserted into the lower casing 3 via a shaft sealing device 20.
The rotating disk 8 is attached to the stationary blade 4, and the striking blade 5 fixed to the upper surface in the vicinity of the outer circumference of the rotating disk 8 is opposed to the fixed blade 4 provided on the inner peripheral surface of the crushing chamber 12. Further, by eccentric the rotating shaft of the rotating disk 8 with respect to the center of the fixed blade 4,
The gap A between the fixed blade 4 and the striking blade 5 is made different at each portion in the circumferential direction.

With such a structure, the kitchen waste W thrown in from the charging port 14 falls on the rotating disk 8 rotated by the drive motor 11, but the kitchen W is driven by the centrifugal force of the rotating disk 8. Moves on the rotating disk 8 in the outer peripheral direction, hits the striking blade 5 and is crushed, and the striking blade 5 and the fixed blade 4
Is sent to the gap A of the impact blade 5 and cut by the outer peripheral surface of the striking blade 5 and the fixed blade 4, falls into the lower casing 3 together with water, and is discharged from the discharge port 13 to the outside. At this time, since the gap A is different in each portion in the circumferential direction as described above, when compared with a model in which the gap A is the same everywhere, the kitchen waste W of a size matching each gap enters the gap A and is cut. As a result, kitchen wastes of various sizes can be efficiently and finely crushed.

[0004]

However, in the above-mentioned prior art, although the gap A is different in each portion in the circumferential direction, since the gap in each portion is always constant, kitchen garbage of various sizes easily enters the gap. However, since there is no means for finely crushing it further, there is a drawback that it takes a lot of time to shear this with a fixed blade for relatively large kitchen waste.

The present invention has been made in order to solve the above problems, and the present invention provides a disposer capable of efficiently pulverizing massive kitchen waste such as relatively large root vegetables and fish heads. To aim.

[0006]

In order to solve the above problems, according to claim 1 of the present invention, a plurality of striking blades fixed to a rotating plate are used as the rotary blades, and a radial gap between the fixed blade and the striking blades is used. The gap changing means is used so that the value changes around the rotation axis of the motor. By changing the radial gap between the fixed blade and the striking blade, you can catch a large chunk of kitchen waste such as root vegetables and fish heads at a large gap, and squeeze the gap that changes due to rotation to crush them. The kitchen waste can be efficiently crushed into small pieces.

According to the second aspect of the present invention, a plurality of striking blades fixed to the rotating disc are used as the rotating blades, and the rotating plate for fixing the striking blades has an elliptical shape. A gap varying means was used in which the radial gap between the fixed blade and the striking blade was periodically changed by fixing the striking blade near the long side and near the short side of the elliptical plate. As a result, it is possible to efficiently grind these kitchen wastes into small pieces by catching a large amount of kitchen waste such as root vegetables and fish heads in a large space and squeezing it between the spaces that change due to rotation.

According to a third aspect of the present invention, a plurality of striking blades fixed to the rotating disc are used as the rotating blades, and the center of the rotating disc to which the striking blades are fixed is mounted eccentrically from the rotation center of the fixed blade. A gap varying means was used in which the gap between the fixed blade and the striking blade was periodically changed by rotating the motor around the rotation center of the blade. As a result, it is possible to efficiently grind these kitchen wastes into small pieces by catching a large amount of kitchen waste such as root vegetables and fish heads in a large space and squeezing it between the spaces that change due to rotation.

According to the fourth aspect of the present invention, a plurality of striking blades fixed to the rotating disk are used as the rotating blades, and the striking blades are arranged so that the gaps between the individual striking blades and the fixed blades are different. A gap varying means was used in which the gap between the fixed blade and the striking blade was periodically changed by rotating this rotating disk with a motor. As a result, it is possible to efficiently grind these kitchen wastes into small pieces by catching a large amount of kitchen waste such as root vegetables and fish heads in a large space and squeezing it between the spaces that change due to rotation.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 3, a crushing chamber 12 and a discharge chamber 7 continuing below the crushing chamber are provided in a casing, a drive motor 11 is connected below the discharge chamber 7, and the drive motor 11 A rotary plate 8 facing the fixed blade 4 of the crushing chamber 12 is fixed to the upper part of the rotary shaft 10, and a striking blade 5 fixed to the rotary plate 8 is arranged near the outer periphery of the rotary plate 8. Further, the rotation of the drive motor 11 causes the gap G between the striking blade 5 and the fixed blade 4 to periodically change. By periodically changing the gap G, a relatively large root vegetable or a large amount of kitchen waste such as a fish head is caught at a large gap, and the fixed blade 4 cuts it while squeezing it while squeezing it into the gap that changes due to rotation. At the same time, it is dropped into the discharge chamber 7.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 3, 1 is an upper casing, 2 is an intermediate casing, 3 is a lower casing, 4 is a fixed blade fixed to the upper casing, and 8 is a rotation fixed to an upper part of a rotary shaft 10 of a drive motor 11. A plate, 5 is a striking blade fixed to the rotary plate, 7 is a discharge chamber, and 10 is a drive motor 11.
Rotating shaft, 11 is a drive motor, 12 is a crushing chamber for crushing the garbage thrown from the inlet 14, 13 is an outlet for the crushed garbage, 14 is an inlet for the garbage, 15 is a water inlet, W is an inlet Indicates a kitchen garbage.

Next, the operation will be described. First, the drive motor 1
When the rotary plate 8 is rotated by 1, the kitchen waste W is charged from the charging port 14 of the upper casing 1, and when it is charged on the rotating plate 8 together with the water supplied from the water supply port 15, the kitchen waste W moves to the rotating plate 8. The upper part is sent to the outer peripheral direction of the rotating plate by centrifugal force,
The striking blade 5 is crushed, pressed against the fixed blade 4, cut by the fixed blade, and then dropped into the discharge chamber 7 through the gap G. At this time, the gap G between the fixed blade 4 and the striking blade 5 cyclically changes according to the rotation of the drive motor 11, so that it is easy to catch garbage of various sizes. In particular, it is possible to efficiently catch lumps of kitchen waste such as relatively large root vegetables and fish heads, which have been difficult to catch in a model with a constant gap, and to pinch them into the changing gap G to crush them.

Next, an example of a method of periodically changing the gap G between the fixed blade 4 and the striking blade 5 according to the rotation of the drive motor 11 will be described. In the example shown in FIG. 4, the rotary plate 8 has an elliptical shape, and the striking blades 5 are fixed near the long side and the short side of the ellipse, respectively. From the above, the fixed blade 4 and the impact blade 5
The gap G can be changed periodically according to the rotation of the drive motor 11.

Next, in the example shown in FIG. 5, the rotary plate 8 has a circular shape, is arranged at a position eccentric from the center of the fixed blade 4, and the striking blade 5 is fixed in the vicinity of the outer periphery thereof. By rotating the rotary plate 8 located at a position eccentric from the center of the fixed blade 4 with a drive motor coaxial with the center of the fixed blade 4, the gap G between the fixed blade 4 and the striking blade 5 can be adjusted according to the rotation of the drive motor 11. Can be changed periodically.

Next, in the example shown in FIG. 6, the rotary plate 8 is formed in a circular shape, and the plurality of striking blades 5 fixed near the outer circumference of the rotary plate 8 are positioned at different gaps G from the fixed blade 4. The gap G between the fixed blade 4 and the striking blade 5 can be cyclically changed according to the rotation of the drive motor 11 by fixing the fixed blade 4 to the fixed blade 4.

[0017]

As described above, according to the present invention, the gap between the fixed blade and the striking blade is changed around the rotation axis of the motor. By changing the gap between the fixed blade and the striking blade, you can catch the bulky kitchen waste such as root vegetables and fish heads where the space is large, and squeeze the kitchen waste by pinching it in the space that changes due to rotation. Can be efficiently crushed into small pieces. In other words, it is possible to provide a very convenient disposer that can be thrown in without worrying about the size of the garbage.
