Description

Electric pressure cooker

The present invention relates to an electric pressure cooker, and more particularly, to an electric pressure cooker capable of automatically sealing and separating the inner container containing the rice cooker lid and rice.

In the old cooking method, where rice was put in a container and water was cooked using a guesswork, the cooker was cooked using thermal power. Electric rice cooker is common.

In addition, a pressure cooker for cooking by raising the pressure of the vessel at the time of cooking using a boiling point of water different according to the pressure was developed. The higher the rate at which the alpha of the starch is alpha, the higher the sweetness, and the higher the rate at which the starch is alpha, the higher the water temperature is near 100 ° C. Higher. In other words, the higher the pressure of the container, the higher the boiling point of water, so the rice in the container becomes more alpha and the taste of the rice is better.

One way to increase the pressure in the container is to ensure that the container containing the rice is sealed during cooking and that the steam generated during cooking is not leaked until a certain pressure, so that the inside of the container is high pressure by steam.

Referring to Figure 1, the operation of the conventional electric pressure rice cooker (Korean Utility Model Publication No. 90-11191) for implementing such a method, the pot body (1) containing the rice in the body 10 is built And the pot body is covered with a cover (9) rotatably coupled to the body. When the cover is covered with the pot body, the pot lid 7 coupled to the bottom of the pot body is coupled to the pot body. Then, the coupling stones 7a of the pot lid are placed in the cutouts 2b and 4b of the pot body and the coupling wheel, respectively. Then, when the handle 5 provided on the pot body rotates, the engaging wheel 4 is rotated so that the engaging portion 4c of the engaging wheel is caught by the engaging stone 7a of the pot lid, so that the pot lid and the pot body are sealed and coupled to each other. If you rotate the pot lid and the pot body is to be separated. Reference numeral 3 is a steam exhaust device.

However, in the conventional electric pressure cooker as described above, since the steam generated during cooking remains inside the pot body even after the cooking is completed, the pot lid and the pot body are firmly coupled by the residual pressure of the steam. Due to this, the handle could not be easily rotated, and thus the pot lid was difficult to be separated from the pot body after cooking.

In addition, the handle also becomes a high temperature due to the heat generated during cooking, there was a disadvantage that the user is burned when grabbing the handle to separate the cooker body and the cooker body after cooking.

In addition, the handle protrudes out of the cooker body, so there was an unsightly disadvantage.

The present invention has been made to solve the above drawbacks, the object of the present invention is to operate by the driving force of the motor to provide a device for combining and separating the inner container and rice cooker lid containing rice, the inner container containing the lid and rice To provide an electric pressure cooker that can be easily coupled, separated.

Another object of the present invention is to provide a device that automatically combines and separates the container containing rice and the inner container while operating by a motor when the switch is turned on, so that the user does not need to operate a handle protruding from the outside of the rice cooker, while aesthetically beautiful. Electric pressure cooker, there is no need to hold the handle of the high temperature by the heat generated during cooking by hand to provide an electric pressure cooker with no fear of burns.
