Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a disposer for processing food waste, and particularly has a rotation speed control section of a motor, and crushes a swing hammer according to changes in the rotation speed of the motor. The present invention relates to a disposer that can suitably crush food waste by changing its parts.

[Prior art]

In general, food waste generated from home kitchens ranges from soft items such as vegetables and fruits to hard items such as fish bones and shells.

As shown in FIG. 1, a conventional garbage disposal disposer has a disk 2 that rotates at a constant speed driven by a motor 1.
and a swing hammer 4 which is supported by a rotatable pin 3 and plays an important role in pulverizing garbage, and a fixed blade 5 on the outer periphery of the disk, which discharges the finely pulverized material together with water. It is mainly composed of a shredder 7 that can run up to 6 liters.

To pulverize food waste using such a disposer, first feed the food waste into the casing 9 through the input port 8 of the disposer installed under the outlet of the sink, and then pour it into the casing 9. Pour continuously. Next, by turning on the motor drive switch and rotating the motor 1, the disk 2 and the swing-arm 4 on the disk 2 are rotated.
Rotate. As shown in FIG. 2(a) and Φ), the thrown food waste is initially moved by the rotation of the swing/arm 4 caused by the disc 2, so that the large food waste 10 is moved to the swing part.
The garbage collides with the hammer 4 and is crushed, and the crushed garbage is then transferred to the gap 12 between the tip 11 of the swing hammer and the shredder 7.
Enter into (t+) and tip 11 of the swing
The garbage is further finely crushed by the fixed blade 5 of the shredder, and the crushed garbage 13 passes through the fixed blade 17 together with water and reaches the drain, completing the garbage pulverizing action of the disposer.

As mentioned above, the action of crushing food waste by a disposer can be broadly divided into two stages. In other words, in the first stage, the large garbage is crushed by the swing tommer so that it can be easily crushed in the next stage, and in the second stage, the garbage that has been finely divided in the first stage is crushed by the swing atomer. The tip of the I-mmer and the fixed blade of the shredder make it even finer, making it easier to flow with water.

Generally, the crushing ability of a disposer depends on the rotational speed of the motor, but when the rotational speed is constant, the crushing time in the second stage greatly affects the crushing ability. That is, the smaller the gap (tl) between the tip of the swing hammer and the fixed blade of the shredder, the faster the processing time. This is because the smaller the gap, the smaller the particles of raw garbage that are pulverized and the easier it is for them to pass through the fixed blade.

However, in conventional disposers, the swinging hammer is supported by a pin, so the gap between the tip of the swinging hammer and the fixed blade of the shredder is always constant at the end of rotation, and the rotation speed of the disc by the motor is also constant. Met. Therefore, since the crushing capacity is always constant, there is a drawback that when there is a large amount of garbage or when there is hard garbage, it is not possible to crush it with a capacity that is suitable for the garbage.

[Purpose of the invention]

The purpose of the present invention is to:
In a disposer that has a control unit that can change the rotation speed of the motor, the gap between the tip of the swing hammer and the fixed blade of the shredder changes depending on the change in the rotation speed. It is an object of the present invention to provide a disposer in which the gap becomes smaller in proportion to the number of rotations and the crushing ability is increased.

[Summary of the invention]

That is, the present invention provides a disposer that can change the motor rotational speed and has a controlling part such as a pole number change, by installing a swing hammer that is freely rotatable and supported by a pin and an elastic piece. When crushing large quantities or hard materials, the rotational speed is increased and the gap between the tip of the swing hammer and the fixed blade of the shredder is shortened, making it possible to significantly increase the crushing capacity. It has been treated. Through such improvements, the present invention provides a disposer in which a crushing capacity suitable for the amount of garbage to be treated and the hardness or softness of the garbage can be selected.

The present invention includes a rotating plate, a swing hammer attached to the rotating plate, and an outer periphery of the rotating plate in a casing having a garbage inlet and a garbage holding part in the upper part and a discharge outlet in the lower part. In a disposer that includes a fixed blade disposed facing a surface and a drive device for the rotary plate, the swing hammer and the fixed blade crush food waste by rotating the rotary plate. , the disposer is characterized in that it is attached so as to be slidable in the radial direction of a rotary plate and is provided with an elastic body that biases the swing hammer toward the center of the rotary plate.

[Embodiments of the invention]

Embodiments of the present invention are shown below in Figures 3 to 8.
This will be explained in detail with reference to the drawings.

FIG. 3 is a partial sectional view of an embodiment of the disposer of the present invention. In the figure, in the disposer main body F, the garbage is urged toward the center of the rotary plate by the rotation of the rotary plate 5, and is moved by an elastic body, that is, the spring 20 in the spring guide 20a in FIG. The shredder 7 has a swing hammer 18 attached to the rotary plate 15, a fixed blade 5 disposed opposite to the outer periphery of the rotary plate 15, and a shredder 7 having a crushing hole 19. In the present invention, the rotation speed of the rotating plate is controlled as shown in FIG. It is controlled by changing the rotation speed of the motor using the switch 1516. (In Fig. 4, for example, ■ is a switch for low speed rotation, ■ is a switch for medium speed rotation, and ■ is a switch for high speed rotation.)
Therefore, depending on the rotation speed of the rotary plate 15, the swing hammer 18 slides in the radial direction with respect to the rotation, and the swing hammer 18 has an influence on the above-mentioned crushing ability.
This means that the gap 12 (tl) between the fixed blade 5 and the fixed blade 5 is changed.

The movement of the swing hammer of the disposer of the present invention will be explained with reference to FIGS. 5 and 6. That is, when the rotational speed of the rotary plate 15 is small, as shown in FIG. 5, the centrifugal force acting on the swing hammer 18 is small, and therefore the elongation of the spring 20 is small, so the gap 22 (12) is large and the crushing capacity is not so great. Does not increase. However, as the rotational speed increases, as shown in FIG.
moving in the radial direction 24 relative to the gap 23 (L3)
becomes small, and the crushing capacity increases according to the rotation speed. In order that the swing hammer 18 can be moved by the spring 20 in this manner, the hole for attaching the entire bottle 3 is, for example, an elliptical elongated hole 21.

In other words, the centrifugal force F acting on the swing hammer is proportional to the square of the rotation speed of the rotary plate, as shown in equation 1, and the spring is stretched by the centrifugal force F, causing the swing hammer to move as shown in equation (2). It becomes.

...... ■: Spring constant x distance of movement of the swing hammer From the above l and formula (■), in the present invention, the gap T between the tip of the centrifugal force F5 swing hammer and the fixed blade and the crushing capacity Q are It is clear that each of them has a relationship with the rotational speed N of the rotary plate as shown in FIG. There is no particular restriction on the method of attachment, as long as the swing hammer is biased toward the center and the swing hammer can be moved by changes in centrifugal force depending on the rotational speed of the rotary plate. For example, as shown in FIGS. 8(a) to (C), the elastic body 26-
i The swing hammer 18 is attached to the inner wall of the hole 27, and the swing hammer 18 moves due to the expansion and contraction of the elastic body 26, and when rotating at high speed, the swing hammer 18 is moved by the centrifugal force 2.
A configuration in which the crushing capacity can be increased by moving in the direction of 5 (position 18a) is also suitable.

(Effects of the Invention) According to the present invention, in a disposer having a control unit that controls the rotation speed, an elastic body such as a spring is provided so that the disposer can freely rotate and move in the radial direction by the centrifugal force 25 generated by the rotation of the rotating plate. By installing a swing hammer that can be used, it is possible to select an appropriate crushing capacity depending on the amount of food waste and the hardness or softness of the food waste.
