Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cooking machine that processes foods such as meat and vegetables using a rotating cutter.

BACKGROUND TECHNOLOGY Conventional cooking machines, such as mixers, rotate a cutter at the bottom of a container at high speed using an electric motor.
Mainly, solid ingredients and liquid ingredients such as water or milk are placed together in a container, and the ingredients are finely ground and stirred to make drinks or prepare food for cooking.

Generally, as shown in FIG. 5, when fitting the lid 6 of these cooking machines with the container 5, the lid 6 is made of an elastic material, and the outer diameter A of the lid 6 that fits into the container 5 is set to the container 5. The lid 6 is inserted into the container while being bent, and is held in the container by the elastic force of the lid 6.

Problems that the invention aims to solve When holding a lid on a container using the elastic force of the lid, the outer diameter of the lid should always be aligned with the inner diameter of the container while the lid is inserted into the container. The force that tries to shrink works, and due to environmental conditions such as ambient temperature and humidity, and changes over time, the outer diameter of the lid gradually decreases, causing the lid to lose its holding power and cause the container to close. There was a risk that the lid would fall off the container just by turning it upside down. Moreover, in order to improve these points, the structure becomes complicated and handling becomes inconvenient.

Means for Solving the Problems The present invention was made in order to solve the above-mentioned problems with conventional cooking machines, and includes a slider for locking the lid on the top of the handle of the cooking container. The lid is provided with a concave portion and an engaging portion, and these are engaged with the outer periphery of the container and the slider, thereby reliably fixing the lid to the container.

Operation When the concave part of the lid is engaged with the outer peripheral edge of the upper part of the container and the lid is rotated using the concave part as a fulcrum, the engaging part of the lid approaches the slider on the upper part of the handle. Then, when the slider is pushed toward the center, it is engaged with the locking body, and the slider returns to the outside due to the biasing force of the coil spring, allowing engagement with the lid. The lid is always held by engagement at two or more places.
