Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric mixer used in general households.

Conventional configurations and their problems In general, electric mixers are designed so that the switch button that operates the motor control switch can only be activated after the container is placed on the mixer body. As shown in the figures and FIG.
When placed on the switch, the movable shaft 2 is moved downward, and the rotatable lever 3 is moved by the movable shaft 2 from the solid line state to the dotted line state, and as a result, the sliding plate 5 of the switch 4 is moved from the lever 3 is released, it moves to the right from the state shown in FIG.
As a result, the operating plate 7 to which the switch button 6 is fixed faces the notch 5a of the sliding plate 5, so when the switch button 6 is pushed against the spring force of the spring 8 in this state, the operating plate 7 7 engages with the notch 5a of the sliding plate 5, and the motor control switch 4 is turned on. On the other hand, when the container is not placed on the mixer main body 1, the lever 3 returns to the state shown by the solid line and moves the sliding plate 5 to the left, resulting in the state shown in FIG. In this state, the protrusion 7 of the operation plate 7 to which the switch button 6 is fixed is
Since the point a faces the flat part 5b of the sliding plate 5, the switch button 6 cannot be pressed and therefore the motor control switch 4 cannot be turned on.

However, in the above conventional configuration, the lever 3 for operating the sliding plate 5 of the switch 4 is
Since the moving direction of the switch button 6 is the same as the moving direction of the sliding plate 5, consideration should be given to changing the position of the switch button 6 relative to the mixer main body 1 and using it differently, as shown in FIGS. 3 and 4. If it is necessary to do so, a lever for the right hand and a lever for the left hand must be provided, resulting in a problem that the structure becomes complicated and the cost increases.

Purpose of the invention In view of the above conventional problems, the present invention provides an electric mixer in which the safety device can be operated with the same lever even when the switch button is used by changing the position of the switch button on the mixer main body. The purpose is to

Structure of the invention In order to achieve the above object, the present invention is a rotatable shaft whose one end is connected to the lower end of a movable shaft provided on the mixer main body so as to be movable up and down, and whose central part is supported by the shaft on the mixer main body. the other end of the lever
It is shaped like a letter, and with this configuration, even if the switch button is to be used by changing its position relative to the mixer body, the same lever can operate the switch's sliding plate. .

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. 5 to 10, 11 is the mixer main body, 12 is a container that is detachably placed on the mixer main body 11, and 13 is the mixer main body 11.
The upper end of this movable shaft 13 protrudes upward from the mixer main body 11, and when the container 12 is placed on the mixer main body 11, the rib provided inside the lower part of the container 12 14 and moves downward. 15 connects the shaft 1 to the mixer main body 11 via a lever support 16.
This lever 15 is a rotatable lever whose central part is supported by
The lower ends of are connected. Reference numeral 18 denotes a motor control switch attached to the mixer main body 11, and the switch 18 is provided with a sliding plate 19 having an inclined surface 19a at its end, which is in contact with the side surface of the other end of the lever 15. . Reference numeral 20 denotes a plurality of operating plates that move in a direction perpendicular to the sliding plate 19;
A switch button 21 is fixed to each. Further, the sliding plate 19 is formed with a notch 19b in which the convex portion 20' of the operating plate 20 engages, and a flat part 19c adjacent to the notch 19b, at a position facing the plurality of operating plates 20. ing. A coil spring 22 is attached between one end of the lever 15 and the lever support 16, and this coil spring 22 constantly urges the movable shaft 13 connected to the one end of the lever 15 upward. 23 is a spring for returning the operating plate 20, and this spring 23 always urges the switch button 21 upward. 24 is the sliding plate 19
This spring 24 biases the end inclined surface 19a of the sliding plate 19 in a direction in which it always comes into contact with the side surface of the other end of the lever 15. 25 is a U-shaped portion formed at the other end of the lever 15.

The operation in the above configuration will be explained. When the container 12 is placed on the mixer main body 11 as shown in FIG. 17 as a fulcrum. As a result, the other end of the lever 15 moves upward to the state shown in FIG. ' are opposed to each other, so when the switch button 21 is pressed in this state, the operating plate 20 moves downward and the protrusion 20' engages with the notch 19b. As a result, the sliding plate 19 is locked and the motor control switch 18 is turned on.

On the other hand, in this state, when the container 12 is removed from the mixer main body 11, the movable shaft 13 is pushed upward by the spring force of the coil spring 22, and the other end of the lever 15 is moved downward, as shown in FIG. do. At this time, the other end of the lever 15 is connected to the inclined surface 19.
The sliding plate 19 is moved from the state shown in FIG.
Push it to the left to move it, as shown in Figure b.
As a result, the convex portion 20' of the operating plate 20 is
As shown in FIG. 9b, since the shape faces the flat part 19c of the sliding plate 9, even if the switch button 21 is pressed in this state, the convex part 2' of the operating plate 20
comes into contact with the flat surface 19c of the sliding plate 19, and therefore, in this state, the motor control switch 18 cannot be turned on.

8a and 8b show an embodiment in which the switch button 21 is used by changing the position of the switch button 21 with respect to the mixer main body 11. In this embodiment, the seventh
Although the direction of the sliding plate 19 is opposite to that of the embodiment shown in FIGS. 7a and 7b, in this embodiment as well, the lever 15 in the embodiment shown in FIGS. Since a U-shaped portion 25 is formed at the end, the sliding plate 19 can be operated using this lever 15.

Effects of the invention As described above, according to the invention, one end of the movable shaft is connected to the lower end of the movable shaft provided in the mixer main body so as to be movable up and down, and the center part is supported by the shaft on the mixer main body. Since the other end of the lever is formed into a U-shape, even if you change the position of the switch button on the mixer body and use it for different purposes, you can operate the sliding plate of the switch with the same lever. As a result, the structure and assembly become simple, and the cost can be reduced.
