The present disclosure relates to a cooking apparatus. More particularly, the present disclosure relates to a cooking apparatus that is configured to heat and stir-fry a food.
In general, stir-fried food, such as a stir-fried spicy pork, a stir-fried Octopus ocellatus, a bowl of stir-fried rice, etc., is prepared in a stir-frying manner where various ingredients are mixed together and are placed in a cooking container such as a frying pan, a pot, or the like, and then appropriately stir-fried while heating and stirring for a predetermined time.
In particular, in order to prepare stir-fried cooking using meat, such as beef, pork, poultry, etc., and various by-products, and also various seafoods such as Octopus ocellatus, Octopus minor, squid, etc., to be tasty, uniform heat should be evenly applied to food ingredients. For achieving this, a chef should continuously perform mixing of the ingredients for stir-fried food in front of a cooking table.
For example, when a chef grabs a handle of a pan and pulls with a small radius snap, then pushes and raises the pan, food ingredients accommodated at a bottom surface of the pan will rise quickly around an inner circumference of the pan and then flip over again to the bottom surface of the pan. In a similar manner, when the chef grabs the handle of the pan and pushes with a small radius snap, then pulls and raises the pan, the food ingredients accommodated at the bottom surface of the pan will rise quickly around the inner circumference of the pan and then flip over again to the bottom surface of the pan. By performing these repetitive movements, stir-fried cooking performed.
However, in order for the chef to flip the food ingredients by using the pan, a snap of a wrist has to be used, and there is a problem in that strain on a wrist joint or an arm joint occurs due repeating of the repetitive snap movement.
In addition, since one chef may only prepare one food at once, it is difficult to prepare a large amount of foods or different types of stir-fried foods at the same time. Therefore, there is a need for solving the problems.

As illustrated in
In addition, water injected from the injecting portion 93 cleans a remnant that has remained in the inner portion 10, and moves downward. A cleaning water moved along the water collecting portion 92 moves outside the body portion 91 through the water draining portion 94.
A temperature of the inner portion 10 is maintained high, and when pressure of water that is injected from the injecting portion 93, contents attached to the inner portion 10 or oil attached to the inner portion 10 may be easily removed.
Hereinafter, another embodiment that the inner portion 200 of the present disclosure is installed in an oval shape will be described with reference to the accompanying drawings.
When it is assumed that the inner portion 200 is rotated in a counter-clockwise direction, a height of contents positioned at a left side is relatively lower than a height of contents positioned at a right side so that the contents positioned at the right side flow down to the left side and are mixed. In other words, when rotating from a wide area of the floor to a narrow area of the floor, the contents positioned at a higher portion flow down to the left side and are in contact with an inner surface of the inner portion 200. Therefore, as the inner portion 200 is rotated, the food 300 is positioned at the bottom portion of the inner portion 200 so that the mixing of the food 300 may be more easily realized.
When the inner portion 200 has a circular cross-sectional shape, the food 300 positioned at a lower side continuously be in contact with the inner surface of the inner portion 200 so that the mixing does not occur well, and is only mixed by the first stirring portion 60 and the second stirring portion 70.
Therefore, when the inner portion 200 has the oval cross-sectional shape, the mixing of the food 300 may be more easily realized.
As illustrated in
Since the plurality of protruding portions 400 rotated together with the inner portion 10 is provided, the food 300 may well be mixed without having a separate stirring wing, or having the first stirring portion 60 and the second stirring portion.
The plurality of the protrusions 400 may be integrally formed with the inner portion 10. When the inner portion 10 is manufactured, the plurality of protruding portions 400 that protrudes inside the inner portion 10 is formed together. In addition, the plurality of protruding portions 400 may be formed to facilitate the mixing of the food 300.
In order to prevent excessive shaking of the inner portion 10 when the plurality of protruding portions 400 is rotated together with the inner portion 10, an installation place and a shape of the plurality of protruding portions 400 are installed in consideration of a center of gravity and a rotation center of the inner portion 10. The plurality of protruding portions 400 according to the present disclosure may be installed along a circumference of the inner portion 10. In addition, the plurality of protruding portions 400 may be spaced apart to each other at a predetermined angle. For example, when only two protruding portions 400 are installed, each protruding portions 400 may be installed at 180 degrees intervals. In addition, when three protruding portions 400 are installed, each protruding portions may be installed at 120 degrees intervals. As such, when the installation number of the plurality of protruding portions 400 is represented to A, 360 degrees divide the A is a set angle.
In addition, a separately manufactured protruding portions 400 may be coupled to the inner portion 10.
Since there is no gap between the plurality of protruding portions 400 and the inner portion 10, a time and a cost that are required to clean the inner portion 10 may be reduced.
As described above, since the rotation and the inclination angle of the inner portion 10 and 200 are capable of being adjusted by using the first driving portion 30 and the second driving portion 40, a time and a cost for preparing the food 300 may be reduced since the food 300 is automatically heated by the heating portion 80 and the direct-firing portion 100. In addition, the food 300 is easily mixed by the first stirring portion 60 and the second stirring portion 70, and the inclination angle of the inner portion 10 and 200 is capable of being adjusted by using the second driving portion 40 so that various tastes of the food 300 may be prepared since the food 300 is mixed and stir-fried in various manners. In addition, since the cleaning of the inner portion 10 and 200 is automatically performed by the injecting portion 93, time and cost required to clean the inner portion 10 and 200 may be reduced.
As described above, the present disclosure is described with reference to the drawings. However, the present disclosure is not limited by the embodiments and drawings disclosed in the present specification. It will be apparent that various modifications may be made thereto by those skilled in the art within the scope of the present disclosure. Furthermore, although the effect resulting from the features of the present disclosure has not been explicitly described in the description of the embodiments of the present disclosure, it is obvious that a predictable effect resulting from the features of the present disclosure should be recognized.
