Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking device for cutting and crushing foods such as vegetables and meat using a cutter, and for stirring liquids such as juices and sauces.

BACKGROUND ART Conventionally, this type of cooking appliance has had a structure as shown in FIGS. 12 to 13. That is, 1 is an electric motor, which is fixed to the chassis 2, and the chassis 2 is connected to the main body 4.
7 is a shaft of the electric motor 1, and a small pulley 8 is attached to the shaft 7 with a nut 3. Small pulley 8 drives large pulley 10 via belt 9. The main shaft 11 is attached to the chassis 2 via an oilless bearing 12. A connector 13 is fixed to the tip of the main shaft 11.
3, the cutter mount 14 is detachable, and a notch 15 provided in a part of the connector 13 fits into a substantially pentagonal protrusion 16 provided on the inner surface of the cutter mount 14, thereby transmitting the power of the electric motor 1. It is becoming more and more common. Two knife-shaped cutters 17 are attached to the cutter mounting base 14 at different levels. A container 18 is positioned and placed on the main body 4 by a substantially cylindrical rib 19 at its lower end. Container lid 2
0 covers the upper end opening of the container 18, and by pushing down the container lid with a switch operation rib 21 provided in a part, the switch operation rib 21 pushes down the switch lever 22 and closes the contact of the switch 23, and power is supplied to the motor 1. supply is becoming available. When the external force on the container lid 20 is removed, the switch lever 22 is pushed up by the spring 24, and the contacts of the switch 23 are opened to cut off the power supply to the motor 1.

25 is a back plate that covers the lower opening of the main body 4, and screws 2
6 is attached to the main body 4. 27 is a leg.

The approximately pentagonal protrusion 16 formed on the cutter mount 14 is formed on the inner surface of the cylindrical portion 28, and fits into the notch 15 of the connector 13 to transmit power. A protrusion 30 at the upper end of the notch 15 whose width is smaller than the inner part 29 of the notch 15 serves to prevent the cutter mounting base 14 from lifting up. The inclined surface 32 provided on the upper end surface of the cylindrical portion 31 of the connector 13 plays the role of guiding the approximately pentagonal protrusion 16 to the notch portion 15 when the cutter mount 14 is fitted to the connector 13. ing.

Problems to be Solved by the Invention However, in a structure in which the notch 15 of the connector 13 and the protrusion 16 of the cutter mount 14 are fitted in only one place, it is difficult to insert the cutter mount 14 into the container 18. If it is set in the main body 4 as it is, there is a high probability that the notch 15 of the connector 13 and the protrusion 16 of the cutter mount 14 will not match, and in this state, the protrusion 16 of the cutter mount 14 will rest on the inclined surface 32 of the connector 13. becomes. When there is nothing in the container 18 other than the cutter 17, the protrusion 16 is guided along the slope 32 to the notch 15 by the weight of the cutter 17. 1
7 and the object to be cut are placed in the main body 4, and when the object to be cut is inside as shown in Fig. 14, the object to be cut is placed between the cutter 17 and the container 18 in the above-mentioned state, that is, the moment the cutter 17 and the container 18 ride on the object. Even if an object is inserted and the cutter mount 14 is pushed down, the protrusion 16 of the cutter mount 14 is not guided to the notch 15 of the connector 13, and operation cannot be performed unless the object to be cut is removed again. Ta.

Therefore, the present invention provides a cooking utensil that prevents the cut object from entering the lower part of the cutter even if the cutter and the cut object are placed in the main body with the cutter and the cut object inside the container, and also improves the ease of cleaning of the inner wall of the cutter mounting base. It is something.

Means for Solving the Problems The technical means of the present invention for solving the above problems is that the shape of the connector is the same as that of the conventional one, and a notch similar to the connector is formed on the cylindrical inner surface of the cutter mounting base. An intermediate shaft is provided between the connector and the cutter mount, and is provided with a substantially pentagonal protrusion that engages with each notch so that it can be fitted from above the cutter mount.

Effect The effect of this technical means is as follows.
That is, if the intermediate shaft and cutter mount are set in the container and only those are placed in the main body, the protrusion formed on the intermediate shaft will be guided to the connector slope by the weight of the cutter mount, as in the conventional case.
Engages with the notch in the connector. This was not possible with the conventional method, as the cutter mounting base can be pressed downward by its own weight plus the weight of the workpiece even if the notch in the connector and the protrusion on the intermediate shaft do not match when the cutter is loaded into the main body while the materials are in the container at the same time. , and only the intermediate shaft is lifted up. If you press down on the intermediate shaft in this state, the connector and cutter mounting base will rotate without lifting up, and the protrusions on the intermediate shaft will be guided and engaged with each notch, allowing you to start operation just by fitting and pushing the container lid. It is.

Embodiment An embodiment of the present invention will be described below based on the accompanying drawings. The structure of the main body part is the same as the conventional example, so the explanation is omitted, and only the fitting parts of the connector, intermediate shaft, and cutter mounting base are shown in Figures 1 to 1.
This will be explained based on Figure 1.

In Fig. 5, 43 is a connector attached to the main shaft 41, and a notch 43' is formed in a part of the connector (detailed explanation of the notch is omitted because it has the same shape as the conventional one.) 33 is the intermediate shaft at the bottom. A substantially pentagonal projection 35 is formed on the inner wall of the cylindrical portion 34, a substantially pentagonal projection 36 is formed on the outer wall portion, and a flange 37 having a larger diameter than the cylindrical portion 34 is formed at the upper end. Reference numeral 44 denotes a cutter mounting base on which two knife-like cutters 47 are mounted with a step difference, and a cutout portion 45 is formed in the inner wall surface of the upper cylinder, and the upper end portion is a fitting portion 40 into which the flange 37 of the intermediate shaft is fitted. It forms.
The approximately pentagonal protrusion 35 formed on the intermediate shaft 33 is formed on the inner surface of the cylindrical portion 34 and fits into the notch 45 of the connector 13.
A substantially pentagonal protrusion 36 is formed on the outer surface of the cylindrical portion 34 , fits into the notch 45 of the cutter mount 44 to transmit power, and extends from the inner part 49 of the notch 45 of the cutter mount 44 . The cutter mount 44 is lifted up until the flange 37 of the intermediate shaft and the fitting part 40 of the cutter mount 44 are completely fitted into the protrusion 50 at the upper end of the notch with a reduced width. This serves to prevent the bottom surface of the container 48 from coming into contact with the bottom surface of the container 48.

Further, the inclined surface 51 on the upper part of the inner wall of the cutter mount 44 serves to guide the protrusion 36 of the intermediate shaft to the notch 45. In other words, with the above configuration, the container lid is pushed, the switch contacts close, and power is supplied to the motor, which is then connected to the connector 43 via the small pulley, belt, large pulley, and main shaft.
When rotates in the direction of the arrow in Fig. 2, the intermediate shaft receives a rotational force A and a downward force B from the connector as shown in Fig. 14, and the intermediate shaft is prevented from lifting upward (this part is different from the conventional example). ) The intermediate shaft and cutter mount 44 are fitted together as shown in FIG. 12, and as shown in FIG.
The flange 37 of the intermediate shaft 33 and the fitting portion 40 fit together, and the shaft rotates with a slight gap between the bottom of the container and the lower end of the cutter mount.

Next, other embodiments of the present invention will be described. In the present invention, notches are provided in the connector and cutter mounting base, and a substantially pentagonal protrusion is provided in the intermediate shaft, but the same effect can be obtained even if this relationship is reversed (not shown).

Effects of the Invention The present invention has a structure in which an intermediate shaft, which is located between a connector and a cutter mount and is formed with a protrusion that engages with the connector and the cutter mount, is interposed from above the cutter mount so that it can be fitted freely. Even if the cutter part and the workpiece are placed in the container at the same time and set in the main body, the cutter part will not lift up and can be operated and cut as is.In addition, when cleaning the cutter mounting base, the intermediate shaft can be removed. Since the central inner wall portion is hollow, it is easy to wash, and both usability and cleanability can be improved.
