Hereinafter, as a specific embodiment of the present invention, a preferred embodiment of the present invention will be described by illustrating the driving mechanism of the present apparatus.

In particular, as will be described later, the outside of the present apparatus is provided with an open switch 110 for opening and closing the middle door, when the outer cover is opened to put food waste, the stirring shaft is stopped, and the middle door is also kept closed. Furthermore, when food is put into the upper middle door and the outer cover is closed, the end portion of the outer cover presses the open switch, and when the outer cover is closed, the middle door is opened by pressing the open switch, in this case, electrically connected stirring The shaft is rotated so that the driving cam is operated at the same time and the intermediate door is closed in order. This will be described in detail below. (The illustration of the outer cover is omitted on Figure 2).

1. Opening mechanism of middle door (The stirring motor stops when the outer cover is opened.)

The middle door 20 is formed inside the main body 10 in which the outer cover C is formed, and the side end portion of the middle door is formed of a fixed shaft 121 and fixed to include a door lever 120 outside the main body. Done. The operation plate 130 which is raised by the rotation of the driving cam 150 is raised to push the fixing lever upward to close the middle door 20. When the operation plate is raised to the highest position by the drive cam, the intermediate door is completely pushed up to close the middle door. In this case, the operation plate is simultaneously caught and fixed to the fixing part P formed on the main body wall at the highest position. . In order to facilitate this role, to form a compound fixing lever 160 on the operating plate that can simultaneously act to push up the fixing lever 120 and to secure the operation plate 130 to the fixing unit. desirable. The composite fixing lever is formed at the end of the operating plate, it is preferable to form a structure that can be fixed to the flexible flexible rotation in the left and right by combining with a predetermined elastic member.

In addition, the open switch 110 is formed to protrude to the upper surface of the main body and the open switch is supported by an elastic body, when pressing the open end of the switch to press the one end of the composite fixing lever 160 When the composite fixing lever 160 is pressed and fixedly rotates to the left side, the intermediate plate is separated from the fixing part P, and the intermediate plate falls freely by gravity. In this case, when the elastic member 131 is placed on the lower side of the intermediate plate, the fall is more stably made. When the operation plate falls, the operation plate supporting the fixed lever disappears, and the intermediate door 20 is opened downward by gravity.

In particular, the pressurization of the open switch 110 is preferably made by the outer cover. Specifically, when the outer cover of the present device is opened, the switch is released, the stirring motor stops, the stirring shaft stops, and the middle door is kept closed. After the food is put in, the outer cover is closed, and when the open switch is pressed by the outer cover, the middle door is opened. When the outer cover is closed, the stirring motor is operated again so that the middle door is closed. . Of course, if the outer cover is closed, the stirring motor will continue to run.

2. Closing mechanism of the middle door (operation of the stirring motor when the outer cover is closed)

When the operating plate 130 is dropped down to fall down, the operating plate is caught by the guide rib 132 formed on the side of the main body and stops, the end portion 140 of the operating plate is the drive cam 150 The front portion of the drive cam is in close contact with the end portion of the drop to the front of the. At this time, the stirring shaft is rotated, the drive cam connected to the stirring shaft is rotated. In this case, the end of the operating plate is maintained in close contact with the front portion of the drive cam, by forming a concave bent in the direction of the central axis at a specific point that meets a virtual straight line connected to the outside from the central axis connected to the stirring shaft It falls into the space of the operation plate guide control unit 152 is formed. This is because the end portion 140 of the operating plate is bent to have elasticity inwardly of the main body, and this elasticity is formed to have elasticity by using the spring agent 141 by forming the operating plate and the end portion separately. It can form (refer FIG. 3 (b)).

The operation plate distal end 140, which is moved to the operation plate guide adjusting unit 152 by a predetermined portion, rides the driving surface F of the driving cam 150. In this case, when it comes into contact with the driving surface, as the moving from the circumferential portion having a short radius from the central axis of the drive cam to the long portion having a long radius, the operating plate is raised, again the operating plate guide adjusting unit 152 If it reaches the end of it, it will be pushed to the highest ascending position. When the operation plate moves up by the driving surface, as described above, the end of the operation plate pushes up the door lever and the middle door is closed.

Referring to Figure 3 will be described in detail the configuration of an embodiment of the present invention.

Shown in (a) is a view of the composite fixed lever 160 of the present invention. The composite lever 160 is coupled to the upper portion of the operating plate, is formed in the shape of an anchor (anchor), the left portion is pressed by the open switch to rotate the fixed portion in the counterclockwise direction as a whole, the upper ring portion It is to be separated from the fixing portion (P) described above to function to lower the operation plate. In addition, the right portion of the composite lever is to act at the same time to push up the fixed lever 120 by the operation plate shown. Of course, in the present preferred embodiment has been described a composite fixing lever having a shape as shown, it is of course included in the gist of the present invention to implement the above-described functions, whatever the shape.

(b) shows the working plate distal end 140 of the present invention.

End portion 140 of the operating plate is preferably formed to have a predetermined elasticity in the lateral direction of the main body, for this purpose is formed of a material having an elastic material, or as a separate member through the elastic body 141 as shown Can be formed. Due to the elastic body, the distal end of the operating plate has a curved shape to slightly enter inward, and the curved surface makes contact with the driving surface of the driving cam as described above.

(c) shows the drive cam 150.

The drive cam of the present invention can be formed by changing any structure as long as the cam of the structure that can basically change the rotational force of the stirring shaft to linear motion. For example, various cam structures, such as a flat cam, a disc cam, a translation cam, a cylindrical cam, can be utilized, and in this preferred embodiment, an embodiment of the disc cam is illustrated.

The driving cam 150 has a predetermined thickness and has a closed shape in which a diameter gradually decreases along a circumference at a specific point A that meets an imaginary straight line connected to the outside from a central axis connected to the stirring shaft. Has The radius (r ₁ ) of the specific point (A) and the central axis of the drive cam is formed in a shape that gradually decreases the radius along the circumferential surface, in particular to form the largest radius (r ₂ ) at point B.

In addition, the operating plate guide adjusting portion 152 is formed between the A and B points, which is formed in a shape to form a concave bent in the central axis direction. This is because when the operating plate is lowered by the pressure of the open switch described above, the operating plate is generally in close contact with the front of the driving plate and falls, and when the driving cam is rotated, the operating plate guide is adjusted while rubbing against the front of the driving plate. When the part 152 is reached, the operating plate end portion 140 is elastically entered into the operating plate guide adjusting portion 152, and the operating plate end portion 140 is brought into contact with the driving surface of the driving cam which is continuously turned. The operating plate will rise.

As described above, the configuration of the drive cam may be applied to any case as long as the cam structure has a structure capable of raising the linear height by the operation plate in addition to the above configuration.

In particular, the operating plate is a follower in the form of a flat plate like the end of the operating plate in the configuration of the cam, but also can be varied in accordance with the shape of the cam, of course. For example, it may be configured in various forms such as a translational flat-face follower, a translational roller follower, a translational point follower.

4 is an operation state diagram illustrating the operation of the drive cam of the present invention and the operation of the operation plate in stages.

In FIG. 4A, when the open switch 110 is pressed, the operation plate 130 is lowered. This lowering action is caused by the force of the driving plate falling freely by gravity and the aforementioned elastic body. The operation plate 130 falls to the front portion of the driving cam 150 when descending. In addition, the operation plate 130 is caught by the guide ribs 132, which are protrusions formed on the inner side of the main body, so that only a predetermined portion thereof can move along the driving surface of the driving cam by the elastic member. When the open switch is pressed (for example, when the outer cover is pressed down), the switch is turned on and the stirring shaft is driven.

As the driving cam rotates as shown in FIG. 4B, the operating plate distal end reaches the operating plate guide adjusting unit 152 at some point, and is moved in such a way that it slightly enters inwardly. In this case, as described above, the end of the operating plate comes into contact with the driving surface of the driving cam, and gradually rises as the driving surface rotates.

What is shown in Figure 4c is a process in which the operating plate is raised upward in accordance with the rotation of the drive surface. As shown in FIG. 4D, at the point where the specific point B of the driving cam and the end of the operating plate 140 come into contact with each other, the composite fixing lever 160 pushes the fixing lever 120 completely and the middle door is closed. At the same time it is caught by the upper portion fixed portion (P) of the compound fixing lever 160 to prevent the operating plate to go down arbitrarily again. The stirring shaft continues to stir until after the outer cover is opened or the open switch is released.

As shown in FIG. 4E, the outer cover is opened and the food waste is closed in the middle door, and then the outer cover is closed, or when the open switch is pressurized, the end of the open switch presses the compound fixing lever 160 at the fixing part P. The process of leaving the operating plate 130 is repeated.

Description of the configuration mechanism of the present embodiment basically described on the basis of the position of the operating plate is two fixed levers on the left and two complex fixing levers, the middle door is divided into two parts, but the structure was described In the case of forming the middle door as one, such a configuration may be formed as one. In particular, the structure in which the middle door is divided into two parts at the center may be formed as shown in FIG. 1B even in this embodiment.
