Description

[Detailed description of the invention] [Technical field] This invention relates to an electric cooking tool for making salad dressings, etc., and improves the means for tightening the cup and bottom lid of the stand to the stand, which has a built-in drive motor, battery, etc. It is something that

[Background technology]

This type of electric cooking utensil includes a cup 1 having a stirring member 9 therein as shown in FIGS. 1 and 2.
It consists of a stand 2 containing a drive motor 11 for the stirring member 9, a battery 12, etc., and a stand bottom cover 3. The cup 1 can be removed from the stand 2 and placed upright on a tabletop or in a refrigerator. When inserting or removing the battery 12, the stand bottom cover 3 is removed from the stand 2.

Therefore, these cup 1 and stand bottom cover 3
It is said that it is convenient to use a method of fitting and unfitting the stand 2 in which the stand 2 is held in the hand and rotated. The problem is the direction of rotation for fitting and removing the cup 1 and the stand bottom cover 3.

Now, for example, if the cup 1 and the stand bottom cover 3 can be rotated in different directions to fit and unfit, then when one of the cup 1 and the stand bottom cover 3 is rotated and removed, the other will be tightened and rotated automatically. As a result, it becomes difficult to remove the cup 1 or stand bottom cover 3 on the side that has been turned in the tightening direction. Furthermore, if the cup 1 and the stand bottom cover 3 are turned in different directions, it is easy to make a mistake in turning each direction.

On the other hand, if both the cup 1 and the stand bottom cover 3 can be rotated in the same direction to engage and disengage them, not only will there be fewer mistakes in the direction of rotation, but when one is removed, the other will be tightened and turned in the same way. There will be no more problems. However, on the other hand, when you turn one to remove it, the other tends to rotate and come off in the same way. In particular, if the cup 1 comes off first when removing the stand bottom cover 3, the user will end up grasping only the stand 2, which shortens the effective grip length, making it difficult to remove the stand bottom cover 3. .

[Purpose of invention]

Focusing on this fact, this invention adopts a form in which the cup and the bottom cover of the stand are both rotated in the same direction to fit and unfit, and it is possible to solve the above-mentioned co-rotation problem as much as possible, and it is especially compact. This eliminates the problem that the cup comes off first when removing the bottom cover of the stand, which is thin and difficult to hold in the hand, thereby making it easier to remove the bottom cover of the stand.

[Summary of the idea]

That is, the present invention is characterized in that the cup and stand bottom cover are both rotated in the same direction to fit and unfit, and the degree of tightening of the stand bottom cover to the stand is smaller than the degree of tightening of the cup.
