Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen waste processing apparatus for crushing kitchen garbage and the like.

[0002]

2. Description of the Related Art Conventionally, as this type of garbage processing apparatus, one shown in JP-A-2-35945 is known. That is, in this, a rotary plate driven by a rotary driving device such as an electric motor to receive the kitchen waste is disposed in the main body having a kitchen throwing port formed in the upper part, and a cylindrical fixed blade surrounding the rotary plate is provided. A crushing tool provided in the main body and rotatably supporting an upper surface of the rotating plate, the crushing tool consisting of a cubic metal piece facing the fixed blade is rotatably supported, and the garbage thrown into the main body together with the waste water is rotated. After it is received by the plate, it is struck by the centrifugal force on the inner peripheral surface of the fixed blade and is crushed by the impact crushing action of the crushing tool, and the crushed garbage is dropped from between the inner peripheral surface of the fixed blade and the outer peripheral surface of the rotating plate. Then, the gas is discharged from the lower discharge port.

[0003]

However, according to the above-mentioned conventional structure, since the garbage is crushed by utilizing the centrifugal force of the crushing tool, the force applied to the bearing and the main body of the rotary plate is relatively small, Although it is easy to design in terms of strength, it has a drawback in that strong kitchen waste like animal muscle and flexible kitchen waste like plant skin are difficult to crush and remain in the body.

On the other hand, it is also known to use a screw blade instead of using the crushing tool. This can be crushed without being restricted by the material of the kitchen waste, but since a relatively large force is applied to the bearing and the main body, a high-strength design is required, the size is increased, and the manufacturing cost is increased.

The present invention has been made to solve the above-mentioned conventional problems, and can exhibit an excellent crushing ability regardless of the material of the kitchen waste, and the design conditions for strength can be relaxed.
It is an object of the present invention to provide a garbage disposal device that can be made compact and low cost.

[0006]

In order to achieve the above object, the present invention provides a rotary plate which is driven by a rotary drive device in a main body having a garbage throwing port formed in an upper portion thereof to receive the garbage from the garbage throwing port. And a crusher for crushing the garbage with a cylindrical fixed blade that surrounds the rotary plate and is fixed in the main body, and a crushing tool that is rotatably supported on the rotary plate. In the processing apparatus, the main body is provided with an injection port for injecting a refrigerating fluid into the garbage thrown from the garbage throwing port prior to crushing.

[0007]

With the above construction, when the kitchen waste is thrown into the main body, a refrigerating fluid, for example, liquefied gas is injected from the injection port to freeze the kitchen waste. When the kitchen waste is frozen, the rotary drive is operated to rotate the rotary plate, and the kitchen waste is crushed by the crushing tool and the fixed blade. At this time, even if the kitchen waste is tough like animal muscle, it becomes very brittle due to the low temperature brittleness associated with freezing, and is thus crushed into pieces. The crushed kitchen waste falls down between the inner peripheral surface of the fixed blade and the outer peripheral surface of the rotary plate and is discharged.

Further, due to the impact crushing action of the crushing tool and the fixed blade, the burden on bearings is lightened, the design conditions for strength are relaxed, the overall size can be reduced, and the cost can be reduced. Becomes

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1 and FIG. 2, reference numeral 1 is a garbage disposal device provided on the bottom plate of the sink 2, and the main body 3 thereof is
It is composed of an upper case 5 having a conical portion 4 and a cylindrical lower case 6. Both cases 5 and 6 are connected to each other by bolts and nuts 7.

At the upper end of the upper case 5, a kitchen throwing port 8 is formed, and at the inner lower part of the upper case 5, a cylindrical fixed blade 9 is provided. A plurality of vertical grooves 10 are formed on the inner peripheral surface of the fixed blade 9. Reference numeral 11 denotes a sealing partition wall provided below the rotary plate which will be described later and provided in the lower case 6, and reference numeral 12 denotes a discharge port formed in the peripheral wall of the lower case 6.

In the upper case 5, a rotary plate 13 for receiving the kitchen waste M fed from the garbage pouring port 8 is arranged at a position surrounded by the fixed blade 9. On the upper surface of the rotary plate 13, a pair of swing hammers 14 as an example of a crushing tool,
14 is provided, each base end portion of the swing hammer 14 is rotatably supported via a pin 15, and each free end faces the inner peripheral surface of the fixed blade 9.

An electric motor 16 as an example of a rotary driving device and a housing 17 thereof are provided below the partition wall 11. The upper end of the rotary shaft 18 of the electric motor 16 is
The nut 19 is connected to the center of the rotary plate 13. As a result, the electric motor 16 rotates the rotary plate 13 around the axis X.

Reference numeral 20 is a through hole formed in the partition wall 11 for penetrating the rotary shaft 18, 21 is a sealing material for the through hole 20, and 22 is a bearing for the rotary shaft 18. Reference numeral 23 denotes an injection port attached to the peripheral wall of the upper case 5 for injecting a refrigerating fluid, for example, a liquefied gas g, to the kitchen waste M injected from the garbage injection port 8. The injection port 23 is connected to the liquefied gas cartridge 25 via a fixed amount discharge valve 24. 26 is the cartridge 2
It is a heat insulating cover that covers the flow path from 5 to the injection port 23.

Reference numeral 27 denotes a water supply pipe for supplying water W from the water supply or the like into the main body 3 from the garbage input port 8 and an electromagnetic valve 28 is interposed. Reference numeral 29 is a controller with a switch that operates the constant quantity discharge valve 24, the electric motor 16 and the solenoid valve 28 in this order.

The operation of the above structure will be described below with reference to FIG. First, while putting the kitchen waste M into the main body 3 through the kitchen waste input port 8 (step S1) and turning on the switch of the controller 29 (step S2), the constant amount discharge valve 24 is opened (step S3), and the liquefied gas cartridge is supplied. The liquefied gas g in 25 is jetted from the jet port 23 toward the kitchen M through the fixed amount discharge valve 24. Therefore, the garbage M receives the liquefied gas g and is frozen.

The controller 29 activates the electric motor 16 with a certain time difference from the start of the injection of the liquefied gas g (step S4). As a result, the rotary plate 13 rotates about the axis X via the rotary shaft 18, and the swing hammers 14 and 14 rotate. And the frozen kitchen waste M
After being received by the upper surface of the rotary plate 13, it is struck by the centrifugal force on the inner peripheral surface of the fixed blade 9, and is crushed by the impact force of the rotating swing hammers 14, 14.

At this time, since the kitchen waste M is fragile due to freezing, it can be effectively crushed even if it is as strong as animal muscle or as flexible as plant skin. Furthermore, since it is a method of impact crushing by utilizing the centrifugal force of the swing hammers 14 and 14, an unreasonable force is not applied to the bearings 22 and the like, and therefore, a high-strength design is not required, resulting in compactness and Cost reduction can be achieved.

After several tens of seconds have passed since the electric motor 16 was started, the controller 29 opens the electromagnetic valve 28 (step S5), and the water W is supplied into the main body 3 by the water supply pipe 27. Then, the crushed garbage M is dropped together with the water W from between the inner peripheral surface of the fixed blade 9 and the outer peripheral surface of the rotary plate 13 as shown by an arrow a in FIG. After this, the controller 29 turns off the switch.
When set to F (step S6), all circuits are stopped (step S6).

By the way, in the above-mentioned embodiment, the liquefied gas of the liquefied gas cartridge 25 is used as the freezing fluid g, and this is supplied to the ejection port 23 through the constant amount discharge valve 24. However, the cold air from the refrigerator may be directly sent to the jet port 23 as the refrigerating fluid g.

[0020]

As described above, according to the present invention, the kitchen waste crushed by the cylindrical fixed blade surrounding the rotary plate disposed in the main body and the crushing tool pivotally supported on the rotary plate is crushed. At that time, since the freezing fluid is sprayed from the spray port provided on the peripheral wall of the main body to the kitchen waste to be frozen, the kitchen waste of various materials is fragile due to low temperature brittleness and can be effectively crushed. it can. Moreover, the strength design is simpler than that of the method of cutting with a screw blade, and it can be manufactured compactly and at low cost.
