[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a juicer for squeezing juice from vegetables and fruits, and a safety device for a cooking machine such as a mixer for cutting and stirring with a cutter.

[0002]

2. Description of the Related Art A safety device for a cooking machine of this type has been disclosed in the prior art.
As shown in 63-189110 (A47J 19), a switch having a switch bar for controlling the drive of the electric motor and disabling the operation when pressed is provided, and the guide plate is provided by the container when the container is placed on the main body. This guide plate pushes one end of a seesaw-shaped lever and raises the other end, and raises an arm provided at the other end. By this operation, the arm is disengaged from the switch bar and the switch can be operated.

Further, when the container is not placed on the main body, the switch cannot be operated because the arm holds the switch bar.

[0004]

In the above-mentioned safety device, since the center of rotation of the lever is at the same distance as the arm mounting position and the distance at which the guide plate presses the lever, It is good if the container to be placed on the body is heavy to some extent, such as a juicer, but if it is a light cup such as an ice cream cup, even if it is placed on the body, the guide plate can not be easily pressed and the clamp etc. I needed a fixture. For this reason, a separate component for fixing is required, and the container and the main body must be formed so that they can be fixed.

Therefore, it is an object of the present invention to provide a safety device for a cooking machine that can operate reliably even with a light weight such as an ice cream cup without providing a fixture such as a clamp.

[0006]

In order to solve such a problem, the present invention provides a main body containing an electric motor, a container mounted on the main body, and a rotary drive in the container by the electric motor. A cutter, a switch provided in the main body for controlling the drive of an electric motor, a switch bar provided in the switch for disabling the operation of the switch by a pressing operation, and a container provided in the main body is placed. And a pusher that is moved by pressing the push bar, and an arm that is horizontally rotatably supported in the main body and that presses the switch bar at one end and a slope that is pressed by the pusher at the other end. And a spring for urging the link in the direction of pressing the switch bar with an arm, the link rotation center is more than the dimension from the rotation center to one end. Characterized in that a longer dimension of the other end.

When the container is placed on the main body, the pusher is pressed by the weight of the container, and when the pusher is lowered, the pusher presses the inclined surface provided at the other end of the link that rotates in the main body. . This pressing causes the link to rotate, the arm provided at one end moves with the rotation of the link, and the arm holding the switch bar disengages from the switch bar so that the switch can be pressed. On the other hand, since the link urges the switch bar in the direction of pressing the switch bar, the switch cannot be pressed when the container is removed from the main body. In addition, the rotation axis of the link presses the inclined surface of the pusher by making the length from the other end where the inclined surface pressed by the pusher is formed longer than the length from the one end where the arm is formed. Even if the force applied is small, the link easily rotates and the operation of the switch bar by the arm becomes reliable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS.

Reference numeral 1 is a main body containing an electric motor (not shown),
Boss 2 from the inside of the upper end of the main body 1 to the approximately central portion downward
Is formed. In addition, a pusher -3 protruding near the center on the upper surface of the main body 1 is provided so as to be vertically movable. The electric motor is turned on and off below the outer wall of the main body 1.
A switch 4 for operating the FF is provided. The switch 4
Is provided with a switch bar 5, the switch bar 5 is operated so that the switch 4 cannot be manually turned on when the switch bar 5 is pressed, and the switch bar 5 is operated when the switch bar 5 is released.
Is operated so that it can be turned on manually.

Reference numeral 6 denotes a container having an upper surface opening which is placed on the main body.
A container lid 7 made of synthetic resin is placed from above so as to cover the upper opening of the container 6.

Reference numeral 9 is a link provided at the lower end of the boss 2 in the main body 1 so as to be horizontally rotatable. The attachment position of the link 9 to the boss 2, that is, the rotation center position 10
As shown in FIGS. 2 and 3, H> h, where H is the length from the position 10 to the slope 11 described below and h is the length from the rotation center position 10 to the arm 12 described below. ing. The arm 12 is integrally formed so as to hang down from one end of the link 9 on the side closer to the switch 4, and the lower end of the arm 12 is positioned so as to press the switch bar 5. Also,
The inclined surface 11 is formed at the other end of the link 9 near the center of the main body 1, and is positioned so that the lower end of the pusher-3 abuts on the inclined surface 11.

Numeral 13 is a spring for urging the link 9 in a direction in which the arm 12 constantly presses the switch bar 5, and is laid across the inside of the main body 1 and the upper portion of the arm 12.

Next, the operation will be described. With the container 6 placed on the main body 1 and covered with the container lid 7 from above, the switch 4 is manually turned on to rotate the electric motor, and cooking is performed using this rotation. .

The use condition at this time will be described in detail. When only the container 6 is placed on the main body 1 or nothing is placed on the main body 1, the pusher 3 is kept raised as shown in FIG. Since the arm 12 keeps pressing the switch bar 5 by the spring 13 provided on the link 9, the switch 4 cannot be manually pressed.

When the container 6 and the container lid 7 are placed on the main body 1, as shown in FIG. 3, the pusher-3 on the main body 1 is pressed and the slope 11 contacting the lower end of the pusher-3 is removed. The lower end of the pusher-3 slides, and the link 9 rotates against the spring 13. Then, the arm 4 formed at the other end of the link 9 separates from the switch bar 5 held by the arm 12 and the switch 4 is manually turned on.

At this time, the rotation center position 10 of the link 9 is set to H>
Since it is h, the link 9 easily rotates even if the pusher 3 exerts a small force on the slope 11, and even if it is a light bottle such as an ice cream bottle, it can be rotated just by placing it, and it can be clamped as before. The attachment can be easily replaced without having to fix it with a fixing tool such as. Furthermore, since the slope 11 is directed upward so as to be close to the pusher-3, the length of the pusher-3 may be short and the slope 11 can be pressed down stably.

[0017]

As described above, according to the present invention, even if a light weight cup, such as an ice cream bottle, is placed on the main body, the safety device operates, so that a separate component such as a fixing tool is not required and the cost is reduced. It does not take effect and is excellent in terms of operation.
