Description

Safety device for food processor container lid

Technical field

The technical solution relates to a safety device for securing the lid of a food processor container where the lid is coupled to a motor mode switch.

BACKGROUND OF THE INVENTION

Known safety devices for this purpose, designed as safety fuses, are solved by mechanically coupling the lid of the food processor container and the electric motor stop control. In such an embodiment, however, the motor cannot be used as an electric brake to stop the rotating blades at the desired time.

Another known solution consists in a microswitch operated lid. In this case, however, due to insufficient number of contact pairs and their maximum current carrying capacity, the motor circuit cannot be switched to electric brake mode.

It is also known that a hinged or hinged lid acts directly or via an intermediate member on a motor mode switch, but additional mechanical locking is required to prevent the lid from automatically detaching, which makes the safety device more complex.

The essence of the technical solution

These drawbacks are largely eliminated by the technical solution of the safety device for securing the lid of the food processor container, where the lid is coupled to a motor circuit mode switch consisting of an inch of the food container lid rotatable from lower position with lid open to upper position with lid extending into a recess in the housing of the robot vessel, wherein the actuator extends into the thumb path, one end mounted rotatably about a pivot relative to the body of the robot vessel carrier and provided with a detent recess for the thumb to arrest the closed lid in the on position. On the one hand, the actuator is in contact with a slide switch fixedly fixed in the beam and on the other hand it is shaped to engage with a rotating lid thumb to convert the rotational movement of the lid into a linear movement to operate the slide switch.

The safety device according to the technical solution is simple and reliable. It allows both the motor circuit to be switched to electric brake mode and to working mode, while the lid is reliably secured against spontaneous release.

Overview of the drawings

The technical solution is explained in more detail by means of the drawings, in which Fig. 1 shows the safety device in the open state, Fig. 2 shows the safety device in the closed state.

Examples of technical solution

The safety device for securing the lid of the food processor container has a thumb 2 arranged on the circumference of the food processor container rotary lid 1 which extends into the recesses in the container housing 8. The thumb 2 is in the open state of the safety device (as seen in Fig. 1) at the bottom of the recess, below and at a distance from the actuator 3, i.e. in its lower position with the lid open i, 2) in the upper part of the recess, in its upper position with the lid 1 closed, where it is in the locking contact with the actuator 3.

A housing 7 is provided in the housing 8 in which a fixed bearing is provided for the slide switch 6 of the motor circuit mode. The switch 6 is in continuous contact with the actuator 3, pivotally mounted about the pin 5 relative to the body of the beam 7 via its axially extending thumb. The actuator 3 extends into the travel of the thumb 2 when the lid 1 is rotated and shaped to come into force contact with the thumb 2. The free end of the actuator 3 is provided with a positive locking recess 4 for the thumb 2 of the lid 1 in order to lock the closed lid even in the closed position of the safety device.

When closing the lid 1 of the food processor container, the thumb 2 moves along a circular path from its lower position when the lid I is open to its upper position when the lid I is closed. an actuator 3, after which it slides to its free end and rotates it around the pin 5. The actuator 3 which is in contact with the withdrawable thumb of the switch 6 converts the rotary motion of the thumb 2 into a linear motion to control the slide switch 6. 6 and pushes it into the switch 6. Thus, the switch 6 is brought from the open state to the closed state. At the end of the movement of the thumb 2 from its lower position to the upper thumb 2 position, it engages in the locking recess 4 of the actuator 3 and the lid 1 is thereby locked when the safety device is engaged.
