The present invention relates to an oven for cooking food by heating food by gas heat or electric heat, and in particular, prevents the door of the oven from overheating, thereby preventing heat loss due to burn prevention and twisting and maintaining durability. It relates to a door cooling device of the oven to enable safe cooking.

In a conventional oven, as illustrated in FIGS. 1 and 2, a gas stove 10 is disposed at an upper portion to heat a cooking vessel and cook, and a gas heat is provided at a lower side of the stove 10. The oven part 20 which heats food and cooks is arrange | positioned, The grill part 30 which grill-cooks fish is arrange | positioned under the oven range part 20, The said gas stove part 10 On the front side of the), an operation unit 40 for operating functions such as function selection of cooking and temperature control time setting is arranged.

An oven door 21 and a grill door 31 are disposed in the oven range part 20 and the grill part 30 so as to be openable and close, and easy opening and closing on one side of the oven door 21 and the grill door 31. The handles 23 and 33 are respectively disposed to make it easy.

The oven door 21 has an oven door 21 on both sides of the oven door 21 to prevent the oven door 21 from overheating due to high temperature heat while the food is heated in the cooking chamber 25 of the oven range 20. Discharge port 27 is formed to discharge the raised air to the outside by the convection phenomenon, the outside air is provided in the lower portion of both ends of the oven door 21 to compensate for the amount of air discharged The inlet 29 is formed to flow into the interior of the 21.

However, the cooling device configured as described above has a disadvantage in that the oven door 21 is not cooled sufficiently by cooling only by the natural convection phenomenon, and the handle 23 is hardly cooled. As the outlets 27 and 29 are located at the side ends of the oven door 21, there is a problem that the assembly with the cooking utensils (sinks, etc.) of the modern kitchen is not smooth.

Conventionally, as shown in FIG. 3 in order to solve the above problems, The outlets 27 and 29 are formed on the front side of the product, and the fan 51 is installed inside the oven door 21 by the bracket 53, and the suction port 29 is opened by the rotational force of the fan 51. Forced suction of air through the forcibly circulated to the discharge port 27, to increase the cooling effect.

However, the cooling device of the oven door 21 configured as described above is noisy as the fan 51 is installed inside the oven door 21, and is also discharged through the upper outlet 27 of the oven door 21. When the hot air is discharged out to the user to open the oven door 21 is inconvenient to use, there is a problem that the handle 23 is rather heated due to the discharged hot air.

Therefore, the present invention is devised to solve the above-described problems, an object of the present invention is to improve the flow of air passing through the oven door to provide a door cooling device of the oven to increase the cooling effect of the door. There is.

The present invention for achieving the above object, in the oven cooking room for heating and cooking food by gas heat or electric heat, and in the oven oven provided with an oven door on one side to open and close the oven cooking room, Suction is provided to have a curved portion in the upper and lower parts of the oven door to facilitate the exhaust An exhaust duct, a communication duct communicating with and disposed in the exhaust duct to form a flow path, a fan duct disposed at one end of the communication duct to form a flow path of air sucked by the rotating fan, and the fan duct And a fan exhaust duct disposed in communication with the fan duct and the hot air exhaust duct to discharge one air through the hot air exhaust duct.

In addition, the present invention, in the oven provided with an oven range having an oven door to heat and cook food by gas heat or electric heat, and a grill unit having a grill door for grill cooking of fish, Suction inside the oven door and grill door to cool the oven door and grill door at the same time A fan disposed at one end of the communication duct to form an exhaust duct, a communication duct disposed in communication with the exhaust duct of the oven door and an exhaust duct of the grill door, and a flow path of air sucked by the rotating fan. It consists of a duct and a fan exhaust duct disposed in communication with the fan duct and the hot air exhaust duct so as to discharge the air passing through the fan duct through the hot air exhaust duct.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to FIG. 4.

In addition, the same code | symbol is attached | subjected about the part same as the part shown in FIGS. 1-3, and the overlapping description is abbreviate | omitted.

As shown in FIG. 4, a gas stove 10 is provided at an upper portion to heat and cook cooking vessels, and a lower portion of the stove 10 is used to heat food by gas heat to cook. The oven 20 is disposed, a lower portion of the oven 20, grill portion 30 for cooking fish is disposed, the front side of the stove 10, the selection of cooking functions, The operation part 40 which operates a function, such as a temperature control time setting, is arrange | positioned, The oven door 21 and the grill part 30 are arrange | positioned so that the oven door 21 and the grill door 31 can be opened and closed. On one side of the oven door 21 and the grill door 31, handles 23 and 33 are disposed to facilitate opening and closing, and the oven range 20 and the grill part 30 are partition walls ( 24 and 34 are divided into an oven cooking chamber 25 and a grill cooking chamber 35, respectively.

Cooling means 60 is disposed at one side of the oven door 21 and the partition wall 24 to prevent the oven door 21 from being overheated by gas heat or electric heat that is heated in the oven cooking chamber 25.

The cooling means 60 is a suction disposed inside the oven door 21 so that air passes through the inside of the oven door 21. Exhaust ducts 61 and 62, a communication duct 63 disposed in communication with the exhaust duct 62 so as to pass air discharged from the exhaust duct 62, and one end of the communication duct 63. A fan duct 65 which forms a flow path of air sucked by the fan 64 which is disposed and rotated in the air; and the fan to discharge air passing through the fan duct 65 through the hot air exhaust duct 66. A fan exhaust duct 67 disposed in communication with the exhaust port side of the duct 65 and the hot air exhaust duct 66 is formed.

One side of the fan exhaust duct 67 is projected and disposed so as to pass through the operation unit 40 so as to have a predetermined height so that the hot heat of the operation unit 40 is discharged simultaneously, thereby cooling the operation unit 40. It is also performed at the same time.
