Description

[Detailed description of the invention] The present invention relates to a shell peeling machine that peels the shells of boiled eggs, etc. by operating a rotating body that is a stirring member, and the protruding plate with protrusions constituting the rotating body is replaced. This structure prevents deterioration of shell peeling performance due to wear of the protrusion plate, and
If necessary, the protrusion plate can be installed by selecting the protrusion degree, number, shape, etc. of the protrusions, and exhibits performance corresponding to the boiled state of boiled eggs and peeling other than boiled eggs, such as potatoes. It is.

Peeling the shell of a boiled egg generally involved applying an impact to a part of the boiled egg to create a crack in the shell, and then using the crack as a tightening tool to peel the shell with your fingers, which took a lot of time. Therefore, a mechanical method has been proposed, and some methods involve peeling shells by agitating a rotating body, but in this method, protrusions are integrally provided on the rotating body, and the protrusions are subject to severe wear due to the egg shells. It was necessary to replace the entire rotating body each time, which was very uneconomical.

The present invention makes it possible to construct a new rotating body equipped with protrusions with good shell peeling performance without having to replace the entire rotating body when the protrusions wear out.Examples of the invention will be described below. do. In the figure,
1 is a cylindrical body with a bottom, and a bottom plate 2 is located in the middle of the height direction.
A water storage tank 1a is formed above the bottom plate 2 by arranging them in a liquid-tight manner. Note that the bottom plate 2 constitutes the bottom of the water storage tank 1a. A rotating shaft 3 protrudes above the bottom plate 2 by passing through its center.
A pin 4 is attached to the rotating body 5, which is a substantially disc-shaped stirring member, to prevent it from turning. The rotary shaft 3 is rotatably supported by a bearing 7 mounted on a shaft case 6, and the rotatable portion 3 above this shaft support portion is held watertight by an oil seal 8 and the shaft diameter is increased. This creates a step difference. Reference numeral 9 denotes a cap having a substantially inverted dish shape, through which the rotary shaft 3 passes through the central portion, and the penetrating portion of the cap 9 is engaged with the step. Further, the lower end surface of the cap 9 is close to the bottom of the water storage tank 1a made of the bottom plate 2.
A is an air pocket formed inside the cap 9.

Reference numeral 10 denotes a planetary gear reduction mechanism connected to the lower end of the rotating shaft 3 below the bottom plate 2. This planetary gear reduction mechanism 10 includes an internal gear, a plurality of planetary gears meshing with the internal gear, a sun gear meshing with the planetary gears, an output section for linking the planetary motion of the planetary gears to the rotating shaft 3, etc. Be prepared.

Reference numeral 11 denotes a motor shaft of a motor 12, the end of which is connected to the sun gear, and the rotation of this motor shaft 11 is decelerated by the speed reduction mechanism 10 and transmitted to the rotating shaft 3. The motor 12 is concentrically fixed to the shaft case 6 via a motor mounting plate 13. A sealing material 14 is sandwiched between the shaft case 6 and the lower surface of the bottom plate 2, and the shaft case 6 is tightened and fixed in a watertight manner with a nut 15 from inside the water storage tank 1a.

The rotating body 5 is composed of a metal or resin disk portion 17 integrally formed with a boss portion 16 in the center having a hole that fits into the rotation shaft 3, and a metal or resin protrusion plate 18. , boss part 16
A notch portion communicating with the hole and into which the pin 4 fits is formed, and the rotary shaft 3 has a structure that can be attached to and detached from the rotating shaft 3 in the longitudinal direction of the shaft. A constricted portion is provided at the upper part of the boss portion 16, and the rotating body 5
It is a handle that you put your finger on when putting on and taking off. The disc part 17 has a diameter that ensures an appropriate clearance between the disc part 17 and the inner surface of the peripheral wall of the main body 1, and has a hole part 17a for fixing the projection plate 18 with screws B. Projection plate 1
8 has a plurality of hemispherical protrusions 19 projecting upward, and is removably fixed to the disk portion 17 with screws B.

The bottom plate 2 has an end portion pushed in to form a stepped portion 20, and this center portion is further extended downward in the shape of a pipe to form a drainage hole 21. The stepped portion 20 of this drainage hole 21 has a filter 22 which has a large number of holes in a net shape and collects waste such as egg shells during drainage.
is installed in a removable manner.

Reference numeral 23 denotes a drainage pipe, one end of which fits into the drainage hole 21 and the other end connected to a drainage hose 24, through which the water in the water storage tank 1a can be discharged to the outside of the machine.

The drain hose 24 is bendable and has a cap having a hook 25 at its tip, and the hook 25 is hooked to a hose hook 26 provided on the upper side of the main body 1, thereby allowing drainage. The hose 24 is held in an upright position.

27 is a leg made of resin that supports the body, and is fixed to an L-shaped leg fitting 28 fixed to the inner surface of the lower end of the body 1. 29 is press-fitted into a hole provided in the leg 27 to increase the diameter of the peripheral wall of the hole, and the bottom cover 30
This is a fixing pin for fitting and fixing the leg 27 to.
A time switch 31 is operated by a knob 32 to control the energization of the motor 12.

In the above configuration, when peeling boiled eggs, the drain hose 24 is raised, water is stored in the water storage tank 1a of the main body 1, an appropriate number of boiled eggs are put in, and the time switch 31 is set to start the motor 12. The rotating body 5 is rotated. The boiled egg receives rotational force from the protruding plate 18
At the same time as the boiled egg collides with the protrusion 19 of the boiled egg, a crack is created in the shell, through which water enters and the gap between the contents and the shell gradually expands, the resistance of the water increases, and the contents and shell gradually separate. is separated and shell peeling is completed.

By carrying out the above-mentioned shell-peeling action, the protrusions 19 of the protrusion plate 18 are worn out, and when the wear becomes obvious, cracks are less likely to occur in the shell when it collides with the shell of a boiled egg. In this case, it is sufficient to remove the screw B and replace the protruding plate 18 with a new protruding plate, and the disk portion 17 does not need to be replaced and can be used as is.
Therefore, it is more economical than replacing the entire rotating body as in the conventional case.

Additionally, there are some differences in the hardness of boiled eggs depending on when they are boiled. In order to peel a soft boiled egg shell, it is necessary to consider the shape, height, number, etc. of the protrusions 19 on the protrusion plate 18. However, since the protruding plate 18 is replaceable as described above, it is possible to obtain a protrusion that can efficiently peel the shell without damaging the boiled egg.

In addition, if there is a protrusion shape suitable for peeling other than boiled eggs, such as potatoes and potatoes, the protrusion plate having the protrusion can be combined into one disc part 1.
7, just replace it and install it.

As described above, according to the present invention, it is possible to selectively attach a protruding plate according to the purpose to one disc part of a rotating body, expanding the range of use of the device, and reducing the wear of the protrusions on the protruding plate. In some cases, only the protrusion plate needs to be replaced, which is economical, and storage of the protrusion plate takes up less space than that of the rotating body and is easier to handle.
