Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch mechanism in a portable food processing mixer, and more particularly, to a drive motor installed inside a main body when a container containing food to be treated is not set in the main body. It is related to a safety switch mechanism that makes it impossible to operate.

[0002]

2. Description of the Related Art As a food processing mixer for crushing, kneading, liquefying food, etc., there has been heretofore been used, for example, Jikkaihei 1-138333.
The one disclosed in Japanese Patent No. 9 has been proposed. This conventional food processing mixer has a main body having a built-in drive motor, a cutter support tool detachably arranged on the upper part of the main body, and a container which is attached and fixed to the cutter support tool to form an airtight processing chamber. The output shaft of the drive motor protruding from the upper surface of the main body and the input shaft of the blade rotatably supported by the blade support are configured to interlock with each other via the connecting mechanism. The switch of the drive motor provided in the main body is operated by the pressing piece provided on the cover that covers the outside of the container.

[0003]

However, in the conventional switch mechanism, since the switch is operated by the pressing piece provided on the cover, it is necessary to make the cover body easy to operate the switch. In addition to the problem that the number of parts increases, there is also the problem that the operability is poor because the pressing piece provided on the cover body that is unstablely set must be operated to pull it down.
The present invention has been made paying attention to such a point, and provides a switch mechanism that can be operated in a comfortable posture and that can not rotate the drive motor unless the container is set correctly. The purpose is to do.

[0004]

In order to achieve the above-mentioned object, the present invention provides an upper part of a main body located on a side part of a container with a tool support having a container fixedly mounted on the upper part of the main body. The switch operation part of the drive motor is arranged,
A drive motor actuating switch is arranged below the switch operating part, and the push button is mounted on the peripheral wall of the main body so that the switch operating part can be moved in and out, and a substantially inverted L that is swingably supported on the back surface of the push button. It is composed of a V-shaped actuating rod and a connecting spring mounted on the back side of the push button and the actuating rod in a state where the upper end of the actuating rod is advanced to the container mounting area side. If the push button of the switch operating part is pressed while not in operation, the operating rod moves in parallel, and it becomes impossible to operate the drive motor operating switch at the lower end of the operating rod, and the container is loaded in the container mounting area. When the push button of the switch operating part is pressed in this state, the upper end of the operating rod is received by the peripheral wall of the container, and the operating rod swings around the contact point as a fulcrum, and the drive motor operates at the lower end of the operating rod. Switch It is characterized in that was configured to work.

[0005]

According to the present invention, the switch operating portion of the drive motor is arranged on the upper portion of the main body located on the side portion of the container with the blade supporting tool to which the container is attached and fixed being mounted on the upper portion of the main body. A drive motor operation switch is arranged in the lower part, and a push button in which the switch operation part is attached to the peripheral wall of the main body so as to be able to move in and out, and a substantially inverted L-shaped operation that is swingably supported on the back surface of this push button. It is composed of a rod and a connecting spring mounted on the back side of the push button and the operating rod with the upper end of the operating rod advanced to the container mounting region side. When the push button of the switch operating part is pressed, the operating rod moves in parallel and the drive motor operating switch becomes inoperable at the lower end of the operating rod, and the switch operating part is pushed with the container mounted in the container mounting area. Bo When the push lever is pressed, the tip of the upper end of the operating rod is received by the peripheral wall of the container, and the operating rod swings around the contact point as a fulcrum to operate the drive motor operating switch at the lower end of the operating rod. Therefore, with the tool support and container set in the main body, by pressing the push button while holding the main body from the side,
The drive motor actuation switch can be activated to rotate the blade. Further, when the container is not set in the main body, even if the push button is pressed, the drive motor operation switch cannot be activated, and the blade cannot be rotated.
