This paper relates to a kitchen crusher that is installed below the sink inlet of the sink and serves to crush and discharge various food wastes. It is to provide.

In general, the kitchen crusher is a grinding chamber 16 is formed below the frame 15 forming the body as shown in Figure 1 and the rotary blade is installed in the grinding chamber is coupled to the rotary shaft 17, The fixed blade 4 is attached to the inner wall of the grinding chamber.

In addition, the rotary blade is composed of the blade body 11, the striking blade 12, the rotary plate 13, as shown in Figures 2 to 3, and the striking blade 12 and the rotary plate 13 are rivets ( 14) is coupled to the blade main body 11, the gear portion (4a) is formed on the inner wall of the fixed blade (4) like the fourth.

And one side of the grinding chamber is connected to the discharge pipe 18 for discharging the crushed food waste to the outside.

Accordingly, when the device is operated, the rotary blade coupled to the rotary shaft 17 is rotated by the driving force of the motor. At this time, when food waste is introduced together with water through the waste inlet of the sink, the grinding chamber 16 is connected to the frame 15. The solid solids (for example, meat bones or fish bones) of the food wastes that are introduced into the ground are crushed by the rotating blow blade 12, and the fibrous residues such as rice grains or kimchi together with the solids crushed by the rotary centrifugal force of the rotary blades. It is crushed by colliding with the fixed blade 4 while moving in the outward direction.

In addition, the crushed dirt is discharged downward through the gear portion (4a) formed in the fixed blade (4) is discharged to the discharge pipe (18).

However, the conventional kitchen waste grinder as described above is due to the rotary centrifugal force of the rotary blade and the shape (step shape) of the hitting blade 12 and the rotating plate 13 to impinge the fibrous debris such as kimchi or vegetables between the blades. And, since it is a structure that is discharged after being crushed, it can be finely ground fibrous residue.

Therefore, the coarse grains of the particles are sandwiched between the rotary blade and the fixed blade is often impossible to discharge. In this case, the motor is overloaded and the rotation is stopped, as well as the motor burnout.

The purpose of the present invention is to improve the structure of the rotary blade so that the fibrous debris can be finely ground.

In order to achieve the above object, the striking blade attached to the rotary blade in this paper is installed at an angle to the axial direction of the rotary blade and is bent at an obtuse angle.

Therefore, food waste is finely crushed while gathering at the blade portion for hitting, and a vertical bent surface and a roulette are formed on the outer circumference of the blade body, so that the fibrous residue can be more finely crushed.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 5 to 7.

5 is a plan view showing a rotary blade in the present invention, wherein the rotary blade is composed of a blade body 1 and a striking blade 2 fixed to an upper surface of the blade body.

Strike blade (2) is approximately bent at an obtuse angle It is in the shape of a ruler and is fixed to the blade main body 1 by being inclined by a predetermined angle α relative to the axial direction of the blade main body 1, and is fixed to the upper surface of the blade main body 1 and the cutting blade 2. A constant angle β is formed between the bent surfaces.

In addition, the bent surface (1a) is bent downwardly formed on the edge portion of the blade body (1), the bent surface (1a) is inclined by a certain angle (γ) in the opposite direction of the rotation direction of the blade body (l) 3) is formed.

This lottery (3) is located inside the gear portion (4a) of the fixed blade (4) during assembly, a fine gap is formed between the rocket and the gear portion.

Therefore, when food waste is introduced into the grinding chamber together with water, the solids are crushed by the striking blade 2, and the fibrous residue is finely crushed between the bent surface 1a and the fixed blade 4 of the blade body 1.

That is, when the fibrous debris falls on the upper surface of the blade body (1), it is collected at the bent portion of the blade (2) by the inclination angle inclined by the angle of the axial direction α of the blade body and is pushed outward again by the rotational centrifugal force. The fibrous dregs pushed outwardly are finely pulverized by causing friction between the roulette 3 formed on the bent surface 1a of the blade body 1 and the gear portion 4a formed on the fixed blade 4. After the discharge pipe is discharged.

In addition, since the roulette 3 formed on the bent surface 1a is formed to be inclined by the angle of γ in the direction opposite to the rotational direction of the blade body 1, fine grinding is performed between the gear portion of the fixed blade and the bent surface 1a. If the fibrous debris is caught, the debris caught by the lottery (3) is protruded in the reverse direction, and the protruding debris is bent angle portion formed between the bent portion of the striking blade (2) and the upper surface of the blade body (1) Gathered again in the outward circulating action is to be finely crushed until the size to pass through the gap between the bent surface (1a) and the gear portion.

As described above, by providing a blade device for finely crushing and discharging the fibrous debris, it is possible to prevent the overload of the motor caused by the finely ground fibrous debris between the blades and to stop the motor. This can prevent the sink's outlet blockage in advance.

Claims (2)

Fixed to be inclined at an angle to the axial direction of the blade body (1) of several striking blades (2) in the shape bent to the blade body (1) of the rotary blade and bent in a vertical direction to the circumferential surface of the blade body (1) Blade device of the kitchen crusher, characterized in that to form the bent surface (1a) and the lottery (3). The blade device of claim 1, wherein the kitchen waste grinder is bent at an obtuse angle of the striking blade (2).
