Referring to FIGS. 1 to 5, according to an exemplary embodiment of the inventive concept, a cooking vessel 100 mainly includes a main body 110 and a heat transferred part 120 to increase heat transfer from a flame on a gas stove and to prevent cooked food from quickly cooling down.


In an exemplary embodiment of the inventive concept, the cooking vessel 100 may include, but is not limited to, a frying pan, a pot, a caldron, and other kitchen utensils for cooking food, such as e.g., boiling, frying, or roasting food.


The main body 110 of the cooking vessel 100 has a cooking space 111 therein. Food is contained in the cooking space 111 and is cooked.


The main body 110 may be formed of, e.g., a metal or reinforced glass that is resistant to heat generated from a gas stove upon cooking.


According to an exemplary embodiment of the inventive concept, the main body 110 has a truncated cone shape in which a cross-sectional area increases upwardly. However, the main body 110 may include, but is not limited to, a circular cylinder shape and various polygonal shapes.


The heat transferred part 120 may include a lower part of the main body 110. The heat transferred part 120 includes a surface to which heat from a flame is transferred. Conventional cookware (not shown) has an overall flat bottom. However, according to an exemplary embodiment of the inventive concept, the bottom of the cooking vessel 100 may be different in shape from the bottom of the conventional cookware.


For example, according to an exemplary embodiment of the inventive concept, the heat transferred part 120 of the cooking vessel 100 includes a plurality of flame transfer grooves 130 that are recessed from an upper part of the heat transferred part 120. The plurality of flame transfer grooves may increase an area through which heat is transferred from a flame to the cooking vessel 100 (the area is also referred to as “heat transfer area”).


For example, the flame transfer grooves 130 may be arranged radially with respect to a center of the heat transferred part 120.


According to an exemplary embodiment of the inventive concept, a middle portion 120a of the heat transferred part 120 may include a flat surface with no groove. The middle portion 120a may be substantially coplanar with the inner bottom of the flame transfer grooves 130.


Each flame transfer groove 130 may be shaped as a fan. The flame transfer grooves 130 each include a flame inward transfer lower part 140 that is recessed from an upper part of the heat transferred part 120 and a flame additional transfer side wall part 150 that connects the upper part of the heat transferred part 120 with the flame inward transfer lower part 140. A flame (or heat from the flame) may be transferred to all of the flame inward transfer lower part 140, the upper part of the heat transferred part 120, and the flame additional transfer side wall part 150.


According to an exemplary embodiment of the inventive concept, the upper part of the heat transferred part 120, the flame inward transfer lower part 140, and the flame additional transfer side wall part 150 each have a flat surface.


For example, the upper part of the heat transferred part 120, the flame inward transfer lower part 140, and the flame additional transfer side wall part 150 may be shaped as substantially a linear square wave when viewed from a side of the cooking vessel 100. According to an exemplary embodiment of the inventive concept, the upper part of the heat transferred part 120 may have substantially the same area as the flame inward transfer lower part 140. Alternatively, the heat transferred part 120 may differ in area from the flame inward transfer lower part 140.


According to an exemplary embodiment of the inventive concept, when the heat transferred part 120 includes the plurality of flame transfer grooves 130 that are recessed from the upper part of the heat transferred part 120, a flame transfer area may be increased. For example, a flame may be transferred to the flame transfer grooves 130 as well as the heat transferred part 120. In other words, the flame may be transferred to the flame inward transfer lower parts 140 and the flame additional transfer side wall parts 150, thus leading to an increased heat transfer from the flame to the cooking vessel 100.


Referring to FIG. 4, areas L2 of the flame additional transfer side wall parts 150 are added to an area L1 of the heat transferred part 120, thus increasing the overall flame transfer area. Accordingly, the heat transfer from the flame to the cooking vessel 100 may be increased.


When the cooking vessel 100 is placed on a cold floor or table after cooking is done, the upper part of the heat transferred part 120 of the cooking vessel 100 is brought in contact with the floor or table, with the flame inward transfer lower parts 140 and the flame additional transfer side wall parts 150 not contacting the floor or table. The flame inward transfer lower parts 140 and the flame additional transfer side wall parts 150 may remain in contact with external heat (e.g., heat from air). Thus, the cooked food in the cooking vessel 100 may be prevented from quickly cooling down.


Accordingly, the cooking vessel 100 with the structure shown in FIGS. 1 to 5 may increase heat transfer from flames to the food and retain the transferred heat for a long time, thus reducing cooking time and keeping the cooked food warm.



FIG. 6 is a side view illustrating a cooking vessel according to an exemplary embodiment of the inventive concept, and FIG. 7 is an enlarged view of a main part illustrating the cooking vessel shown in FIG. 6, according to an exemplary embodiment of the inventive concept.


Referring to FIGS. 6 and 7, according to an exemplary embodiment of the inventive concept, the cooking vessel 200 includes a main body 210 and a heat transferred part 220.


The heat transferred part 220 includes a plurality of flame transfer grooves 230, each of which includes a flame inward transfer lower part 240 and a flame additional transfer side wall part 250.


In this structure, an upper part of the heat transferred part 220 and the flame inward transfer lower part 240 each have a flat surface, and the flame additional transfer side wall part 250 has an inclined surface, e.g., with respect to the floor. The upper part of the heat transferred part 220 and the flame inward transfer lower part 240 may be parallel with each other.


The flame inward transfer lower part 240 may have an area greater than an area of the upper part of the heat transferred part 220. When the cooking vessel 200 is placed on a table, the upper part of the heat transferred part 220 having a relatively smaller area is brought in contact with the table, thus further preventing the cooked food from quickly cooling down.


According to an exemplary embodiment of the inventive concept, the cooking vessel 200 having the structure shown in FIGS. 6 and 7 may receive more heat from a gas stove flame and may prevent the cooked food from quickly cooling down.

According to an exemplary embodiment of the inventive concept, the area of the flame inward transfer lower parts 340 may be greater than the area of the upper part of the heat transferred part 320. In such case, when the cooking vessel 300 is placed on a table, the upper part of the heat transferred part 320 having relatively a smaller area is brought in contact with on the table with the flame inward transfer lower parts 340 and the flame additional transfer side wall parts 350 not contacting the table, thus preventing the cooked food from quickly cooling down.


According to an exemplary embodiment of the inventive concept, the cooking vessel 300 having the structure shown in FIGS. 8 and 9 may receive more heat from a gas stove flame and may prevent the cooked food from quickly cooling down.
