Description COOKING APPARATUS CAPABLE OF ADJUSTING ITS HEIGHT [0002]

Disclosure of the present invention relates to a cooking apparatus capable of adjusting the height of a food cooker such as a grill or a vessel, and is configured to be able to move a cooking compartment supporting the food cooker upward or downward, To the cooking device.

Herein, the background art relating to the present invention is provided, and they are not necessarily referred to as known arts.

In general, when grilling meat (hereinafter referred to as "meat") such as chicken or pork or beef, the grill or grill plate is placed on the top of a cooking device supplied with charcoal or gas heat, and then a gas or charcoal It uses heat to feed the meat and grill it.

However, when the meat is baked by using the gas or the charcoal grill such as charcoal, the meat is directly heated so that the outside of the meat can be easily cooked while the inside is not cooked. When the meat is cooked to the inside, Sometimes the outside gets on first and the meat is thrown away.

In order to solve this problem, a cooking apparatus capable of height adjustment is provided in the Korean registered utility model 20-0468275, Korean registered utility model 20-0454953, Korean public utility model 20-2008-0003396, and Korean registration office 20-0317013 However, in these cases, since the height adjustment is performed in units of the set interval, it is difficult to finely adjust the height according to the strength of the thermal power.

In this regard, Korean Utility Model No. 20-0454953 proposes to adjust the height by using a rack and a pinion. However, since the pin is used to fix the adjusted height, it is not easy to fix, There was this difficult problem.

In addition, in the conventional cooking apparatuses capable of adjusting the height, the height adjustment structure and the adjustment height fixing structure are separated from each other, so that it is very difficult or inconvenient for the user to adjust the height.
