Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a safety device for an electric cooker that cuts vegetables, meat, etc. with a rotating cutter.

Structure of conventional examples and their problems In conventional electric cookers, the braking mechanism was mainly an electric means that applied the back electromotive force of the electric keyaki due to inertia, but in the case of a commutator motor. Brush wear 9
Various problems remain, such as an increase in the number of poles due to circuit reversal, and the resulting complication of wiring connections. There are also some brake systems that use mechanical brakes, but these have the disadvantage that the brake shoes and brake drum are always in contact with each other when the vehicle is stopped, resulting in reduced performance.

At present, major problems remain in terms of durability, etc.

OBJECTS OF THE INVENTION In view of the above-mentioned problems, the present invention provides a safety device for an electric cooking appliance that safely and reliably suppresses the inertial rotation of the cutter when the power is turned off, and has improved durability.

Structure of the Invention In order to achieve the above object, the safety device for an electric cooker of the present invention has a main body containing a built-in electric motor, a container placed on the main body, and a cutting blade. A cooking device comprising a driven cutter and a container lid that covers the frontage of the container, which is interlocked with a protrusion provided on the outer periphery of the container lid, an opening/closing arm, and a brake shoe provided in the main body. This configuration includes a brake mechanism that opens and closes the power supply circuit using a brake arm when the container lid is opened and closed, and that temporarily suppresses the inertial rotation of the cutter when the power is turned off. With this configuration, inertial rotation of the cutter can be safely and reliably suppressed, and durability can also be improved.

Description of examples An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a main body with a built-in electric motor 2, and a container 3 is detachably installed on the upper part of the main body.

Reference numeral 4 denotes a container lid equipped to cover the upper opening of the container 3, and a projection 5 is arranged on a part of its outer periphery. A cutter 6 has a cutting blade and is rotated at high speed by an electric motor 2, and is housed inside the container 3. 8 is the main axis,
A cutter 6 is detachably attached to the end of the shaft protruding into the container 3.

9 is a brake shoe, and 10 is a brake drum that is interlocked with the electric motor 2. Further, reference numeral 11 denotes a brake arm, which is properly supported by a guide groove 12 vertically provided on the outside of the container 3, and whose lower end is connected to a spring that interlocks with the brake shoe 9 via a connecting rod 13 supported by the main body 1. It is connected to the middle of 14.

The spring 15 is used to constantly push up the arm 11. Reference numeral 16 denotes an arm for opening and closing the power supply, which is always urged upward, and is arranged in parallel with the arm 11, and operates by a similar interlocking mechanism to open and close a power switch (not shown). Further, the protrusion 6 has a downwardly chevron-like shape along the vicinity of the outer periphery of the container lid, and acts on the two arms 11 and 16 with a slight time delay when the container lid 4 is properly fitted.

And the above-mentioned brake drum 10.7-m11.1
6 and the protrusion 6 constitute a brake mechanism.

In the above configuration, when the container lid 4 is opened, as shown in FIG. 2 C9 and FIG. I haven't been.

FIG. 2C9 FIG. 3A shows the device when the container lid 4 is attached. At this time, only the arm 16 is pushed by the protrusion 6, the power is turned on, the electric motor 2 rotates, The cutter 6 rotates to cut the material.

On the other hand, the arm 11 is located at the base of the protrusion 6 and is not in operation, so that no brake is applied. When the container lid 4 is removed from this state (FIG. 2C and FIG. 3B), the arm 16 first comes off the top of the protrusion 5 and rises upward, and the power is turned off and the arm 11 is pushed by the protrusion 6. The spring 14 is pressed through the connecting rod 13, and the brake shoe 9 is pressed against the brake drum 1o to apply the brake.

Even if an attempt is made to remove the container 3 in this state, the lower end of the arm 11 is stuck inside the main body 1 and cannot be removed. If you try to remove it, see Figure 2 A.

The container lid 4 must be moved to the state shown in FIG. 3A, and therefore the brake is applied only during the attachment and detachment of the container lid 4, which prevents deterioration of braking performance due to unnecessary long-term contact of the brake shoe 9. This will not cause damage and will improve durability. Incidentally, when the container lid 4 is installed as shown in FIG.

Effects of the Invention As is clear from the description of the embodiments above, the present invention provides a simple and reliable brake mechanism as a safety device for electric cookers, thereby suppressing inertial rotation when the cutter is powered off, thereby achieving safety. In addition to being able to improve durability, by making it work only when attaching and detaching, it greatly contributes to improving durability.
