Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is directed to an electric processor called a food processor, which is used mainly in households to chop carrots, onions, etc., or to cut meat cubes into minced pieces. It is related to cooking utensils.

Structure of conventional example and its problems In this type of conventional electric cooker, a container is fixed to a main body with a built-in electric motor, and a cutter with two knife-shaped cutters attached at the top and bottom is installed inside the container. It was common practice to insert an object to be cut, such as a carrot, and fix the container lid to the container, and then operate a switch to transmit the rotation of the electric motor to the knife cutter to cut the object.

In the conventional system configured in this way, it is necessary to operate the switch after fixing the container lid to the container, so two operations are required: fixing the container lid and operating the switch.
Therefore, there was a problem in terms of ease of use.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems and aims to improve operability.

Structure of the Invention In order to achieve the above object, the present invention has a main body in which a part of the main body containing an electric motor is made to protrude in the vicinity of the opening of the container, and a thin slit with at least one end face open is formed on the upper surface of this protruding part. A sliding plate is provided on the bottom of this groove that is linked to a switch that completely controls the energization of the motor. On the other hand, the container lid that covers the opening of the container installed on the main body is provided with the slit. A protrusion is formed that fits into the shaped groove, and by moving the container lid up and down, the protrusion operates the sliding plate to turn on and off the switch. According to this configuration, The switch can be turned on and off simply by moving the container lid up and down, which significantly improves its operability, and the sliding plate that interlocks with the switch is a part of the main body that houses the electric motor. provided on the bottom surface of a narrow slit-shaped groove provided in the container lid, and a protrusion provided on the container lid is inserted into the groove,
Since the sliding plate is operated by this protrusion, for example, the sliding plate may be easily moved by a fingertip other than the protrusion (-1: No, and therefore its safety is reduced. It is something that can be obtained at an extremely high price.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 9, reference numeral 1 denotes an electric motor, which is attached to a chassis 2 with screws 3, and the chassis 2 is attached to a main body 4 via a cushion rubber 5 with screws. 7 is a rotating shaft of the electric motor 1, and a pinion 8 is attached to this rotating shaft 7. Reference numeral 9 denotes an output gear, which is driven by the pinion 8 and is mounted at 1° from the main shaft. Further, the main shaft 10 is attached to the chassis 2 via an oilless bearing 11,
A connector 12 is attached to the tip. A cutter mount 13 is detachably attached to the connector 12, and the cutter mount 13 includes:
Since the upper part of the connector 12 fits into a groove provided in the cutter mount 13, the force of the electric motor 1 is transmitted through these. Further, two knife cutters 14 are attached to the cutter mounting base 13KU, upper and lower. 15 is a container detachably attached to the main body 4, and 16 is a container lid that covers the opening of the container 15, and is detachably attached to the container 16.

17 is a projection provided on the outside of the container lid 16; 18 is a main body 4;
This upper body 18 is an upper body that covers the upper surface of the.

A narrow slit-shaped groove 19 is formed on the upper surface of the container lid 16 into which a protrusion 17 provided on the container lid 16 can be slid up and down. 20 is a small hole provided in the bottom surface 21 of the groove 19, and a sliding plate 23 is inserted into this small hole 20 with a rubber gasket 22 as a seal.
is inserted.

24 is a coil spring supporting the sliding plate 23.

This microswitch 25 is a microswitch for operating the 25-volt electric motor 1, and its contacts are operated by a sliding plate 23. 26 is the end opening 1 of the groove 19
127 is a back plate that covers the lower part of the main body 4, and 28 is a leg attached to the back plate 27.

Next, the operation and operation of the electric cooker will be explained. The container 15 is attached to the main body 4, and the knife cutter 14
The cutter mounting base 13 with the attached cutter mount 13 is fitted into the connector 12. Next, the object to be cut, such as carrots, is put into the container 15,
Then, the container lid 16 is set so as to fit into a narrow slit-shaped groove 19 provided in an upper body 18 that covers the opening of the container 16 and in which the protrusion 17 covers the upper surface of the main body 4. At this time, since the sliding plate 23 and the coil spring 24 push up the projection 17, the container 15 and the container lid 1
There is a slight gap between 6 and 6. From this state, when the container lid 16 is pushed downward with external force by hand, the container 1
Since the container lid 16 moves downward by the gap between the container lid 16 and the container lid 16, the protrusion 17 pushes down the sliding plate 23. As a result, the sliding plate 23 turns on the microswitch 25, causing the electric motor 1 to rotate. This electric motor 1
The rotation is transmitted to the knife cutter 14 and the object to be cut is cut. After cutting the object to be cut, when the external force that was pushing down the container lid 16 is removed, the coil spring 24 moves against the sliding plate 2.
3, the microswitch 25 is activated in the OFF state to stop the rotation of the electric motor 1.

Here, in the conventional electric cooker, the container is fixed to the main body and the container lid is fixed to the container, and then the electric motor is operated by a separately provided switch, but in one embodiment of the present invention, , the switch 25 is turned on only while an external force is applied to the container lid 16, and the switch 25 is turned off immediately when the external force is removed. established,
The feature is that a protrusion 17 provided on the container lid 16 is fitted into this groove 19. In other words, the sliding plate 23 for operating the switch 25 is inserted into the narrow slit-shaped groove 1.
9, the sliding plate 23 cannot be easily moved with fingertips other than the protrusion 1 of the container lid 16, as shown in FIG. This is extremely expensive. Also, the slit-shaped groove 1
At least one end surface of the groove 9 has an opening surface 26 as shown in FIGS. 7 and 8, so even if liquid foreign matter such as water enters the groove 19, it cannot flow out through the opening surface 26. , Therefore, the small hole 2 provided in the bottom surface 21 of the groove portion 19
0 and the rubber packing 22 will not enter the inside of the main body 4. In addition, since the sliding plate 23 and the like that operate the groove 19 and the microswitch 25 are all provided on the main body 4 side instead of on the container 15 side, the container 15 and container lid 16, which are easily soiled, can be made into a simple shape. As a result, cleaning after use can be facilitated. Furthermore, the bottom surface 21 [S of the slit-shaped groove portion 19
If a downward slope is provided toward the opening surface 26 with the entire position of the sliding plate 23 as a reference as shown in FIG. Since this improves the resistance, it is possible to further prevent foreign matter from entering the main body 4 through the small hole 20 and from becoming stuck.

Effects of the Invention As described above, according to the present invention, the switch can be turned on and off by simply moving the container lid up and down, so the operability is significantly improved, and the switch is interlocked with the switch. The sliding plate is provided on the bottom of a thin slit-shaped groove provided in a part of the main body that houses the electric motor, and a protrusion provided on the container lid is inserted into the groove. Since the sliding plate is made to move, the sliding plate will not be easily moved by, for example, a fingertip other than the protrusion, and therefore, extremely high safety can be achieved. .
