Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a so-called food processor, which is used mainly for chopping carrots, onions, etc., and cutting cubes of meat into minced pieces for general household use. This is related to electric cookers.

Conventional structure 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 stand with two knife-shaped cutters attached to the top and bottom is installed inside the container. It was common practice to insert the object to be cut, such as a knife, to fix the container lid to the container, and then operate a switch to transmit the rotation of the electric motor to the knife cutter, thereby cutting 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. There was a problem with this point.

Purpose of the invention The present invention solves the above-mentioned conventional problems.
In addition to improving operability, the container lid can be positioned and prevented from rotating when attached to the container, and the container lid can be easily removed even when the cutter suddenly stops rotating. The purpose of this invention is to provide an electric cooker without

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 the electric motor projects to the vicinity of the opening of the container, and at least one end of the main body has an opening on the upper surface of the projecting part to the outside of the projecting part. A sliding plate interlocked with the switch is provided on the bottom of the groove, and a container lid that covers the opening of the container installed on the main body has a slit-like groove formed on the main body. Forms a protrusion that goes into the groove,
By moving the container lid up and down, the protrusion operates a sliding plate to turn on and off the switch,
When the switch is in the OFF state, fit the protrusion provided on the container into the slit-like groove provided on the main body, and align the shape of the slit-like groove and the protrusion provided on the container lid with the inner circumference of the container. It is formed in a non-circular shape. With this configuration, the switch can be turned on and off by simply moving the container lid up and down, which significantly improves operability and eliminates the need for protrusions. When the container lid is attached to the container by fitting the slit-shaped groove,
Since the shape of the slit-shaped groove and the protrusion provided on the container lid are not circular with respect to the inner circumference of the container, the position of the container lid can be regulated and prevented from rotating. When the external force that operated the switch is removed by pressing the container lid, even if the main body swings slightly due to the reaction caused by the sudden stop of rotation of the cutter, the container lid will not come off from the container. .

A cutter mount 13 is detachably attached to the connector 12, and the upper part of the connector 12 fits into a groove provided in the cutter mount 13, so that the electric motor 1 power is now being transmitted. In addition, the cutter mounting base 13
Two upper and lower knife cutters 14 are attached to the. Reference numeral 15 is a container lid that is detachably attached to the main body 4. A container 16 is a container lid that covers the opening of the container 15, and is detachably attached to the container 15. 1
7 is a protrusion provided on the outside of the container lid, 18 is the main body 4
The upper body 18 has a thin slit-like shape in which a protrusion 17 provided on the container lid 16 is vertically slidably fitted into the upper body, and at least one end is opened to the outside of the upper body 18. A groove portion 19 is formed. Reference numeral 20 denotes a small hole provided in the bottom surface 21 of the groove portion 19, and a sliding plate 23 is inserted into the small hole 20 with a rubber gasket 22 as a seal. 24 is a coil spring supporting the sliding plate 23. Reference numeral 25 denotes a microswitch for operating the electric motor 1, and a contact point of this microswitch 25 is operated by a sliding plate 23. 26 is a back plate that covers the lower part of the main body 4, and 27 is a leg attached to the back plate 26.

Next, the operation and operation of the electric cooker will be explained. A container 15 is installed on the main body 4, and a cutter mount 13 to which a knife cutter 14 is attached is fitted into the connector 12. Next, the object to be cut, such as carrots, is put into the container 15, and the container lid 16 is
is set so that it covers the opening of the container 15 and the protrusion 17 fits into a narrow slit-shaped groove 19 provided in the upper body 18 covering the upper surface of the body 4.
At this time, since the sliding plate 23 is urged by the coil spring 24 and pushes up the protrusion 17, a slight gap h is generated between the container 15 and the container lid 16. From this state, when the container lid 16 is pushed downward with external force by hand, the gap h between the container 15 and the container lid 16 is
Since the container lid 16 moves downward by that amount, the protrusion 17 pushes down the sliding plate 23. As a result, the sliding plate 23 turns on the micro switch 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 pushes up the sliding plate 23, so the micro switch 25 is turned off and the electric motor 1 is turned off.
stop the rotation.

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 activated only while applying an external force to the container lid 16.
is turned on, and as soon as the external force is removed, switch 25 is turned on.
In the configuration in which the upper body 18 of the main body 4 is turned off, a thin slit-shaped groove 19 with at least one end opening outward of the upper body 18 is provided on the upper surface of the upper body 18 of the main body 4, and the container lid 16 is installed on the container 15 and the upper body 18. If the micro switch 25 is in the OFF state, the groove 19
It is characterized in that the protrusion 17 of the container lid 16 fits into the container lid 16, and the groove 19 and the protrusion 17 are provided in a shape that is not circular and concentric with the inner circumference of the container 15.
In other words, the liquid that has entered the groove 19 can easily flow out, and once the container lid 16 is attached to the container 15, the position of the container lid 16 is regulated and the rotation is prevented, and the container lid 16 can be moved around the inner circumference of the container 15. Even if an attempt is made to rotate the container lid 16, the container lid 16 is held at a predetermined position without coming off. Furthermore, even if the main body 4 swings slightly due to the reaction caused by the sudden stop of rotation of the cutter 14 when the external force that operated the micro switch 25 is removed by pushing the container lid 16, the container lid 16 can be easily removed from the container 15. It does not come off, and the container 1
5 is set freely in the main body 4, the container lid 16 can always be placed in a predetermined position.

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. Since the slit-shaped groove is opened, the liquid in the groove can be easily drained, and when the container lid is attached to the container by fitting the protrusion and the slit-shaped groove, the slit-shaped groove and the container Since the shape of the protrusion on the lid is not circular and concentric with the inner circumference of the container, it is possible to regulate the position of the container lid and prevent it from rotating. Moreover, with this configuration, the switch can be operated by pushing the container lid. Even if the main body swings a little due to the reaction caused by the sudden stop of rotation of the cutter when the external force that was causing the cutter to stop rotating is removed, the container lid will not easily come off from the container.
