Abstract

PURPOSE: A microwave oven is provided to equally heat food without changing a position of food by installing heat radiating plates on each inner surface of a cooking chamber. CONSTITUTION: A magnetron(206) is installed in an electronic part chamber(204) for generating electro magnetic waves. The electro magnetic waves are transferred to an inside of a cooking chamber(202) for heating food. Heat radiating plates(208) are attached to upper and lower surfaces, and right and left sides, and a rear surface of the cooking chamber so that the food is heated from upper and lower surfaces, and right and left sides, and the rear surface. An insulating pad(214) is attached to an outer surface of the cooking chamber to minimize heat loss.

Description

Microwave {MICROWAVE OVEN}

The present invention relates to a microwave oven, and more particularly to a microwave oven having additional heating means other than the magnetron.

In general, a microwave oven heats food using electromagnetic waves generated from a magnetron. If a separate heater is added to such a general microwave oven, it is possible to have various cooking functions such as baking or broiling.

1 is a view showing a microwave oven having a conventional heater. As shown in FIG. 1, the magnetron 106 for generating electromagnetic waves is installed in the electric chamber 104, and the electromagnetic waves generated from the magnetron 106 are transferred into the cooking chamber 102 to heat food. A heater 108 that generates heat is fixedly installed on an upper surface of the cooking chamber 102, and heat generated by the heater 108 heats food from the upper side.

Since the heater structure of the conventional microwave oven intensively heats food in one direction, a cooking result in which a portion of the food is taken and partly unripe may be generated depending on the position of the food. In order to prevent this, the user has to open the door of the cooking chamber in the middle of the cooking mode and change the position of the food.

The microwave oven according to the present invention is provided with heating plates on each of the inner surfaces of the cooking chamber so that the food is heated evenly, so that the user can obtain a uniform cooking result without changing the location of the food.

In the microwave oven according to the present invention, the wall surface of the cooking chamber is made of a heating material, which is heated by electromagnetic waves to generate heat. The heating material forms upper and lower surfaces, left and right side surfaces, and a rear surface of the cooking chamber, respectively, so that heat is generated evenly in each direction inside the cooking chamber.

Alternatively, a heating plate may be attached to the wall surface of the cooking chamber of the microwave oven according to the present invention. In this case, the heating plate is made of a heating material that is heated by electromagnetic waves to generate heat, and is attached to the upper and lower surfaces, the left and right sides, and the rear side of the cooking chamber to generate heat evenly in each direction inside the cooking chamber.

A preferred embodiment of the microwave oven according to the present invention as described above will be described with reference to FIG. 2. 2 is a view showing a microwave oven having a heating plate according to the present invention. As shown in FIG. 2, the magnetron 206 for generating electromagnetic waves is installed in the electric field chamber 204, and electromagnetic waves generated from the magnetron 206 are transferred into the cooking chamber 202 to heat food. The heating plate 208 is attached to each side except the front surface of the cooking chamber 202, that is, the upper and lower surfaces, left and right sides, and the rear side, and the heat generated from the heating plate 208 causes the food to be left, right, top and bottom, respectively. Heating. The heat generating plate 208 is heated by electromagnetic waves generated from the magnetron 206 to generate heat. The heat insulating pad 214 is attached to the outer surface of the cooking chamber 202 to prevent heat generated inside the cooking chamber 202 from escaping to the outside, thereby minimizing heat loss.

The heating plate 208 of the microwave oven according to the present invention is made of a heating material such as iron oxide, tin alloy, or ferrite, which is heated by absorbing electromagnetic waves generated from the magnetron 206. Since the heating plate 208 made of such a heating material is attached to each surface inside the cooking chamber 202 of the microwave oven, heat may be evenly transmitted to food in the cooking chamber 202 to cook.

The heating plate 208 of the microwave oven according to the present invention may form a wall surface of the cooking chamber 202 by using a heating material, or form a wall surface of the cooking chamber 202 with a non-heating material and then generate a heating material on the surface thereof. It is also possible to attach and use a heating plate.

Since heat is generated inside the cooking chamber 202 and heat may be emitted to the outside when cooking is performed, the heat insulator 214 is attached to the outside of the cooking chamber 202 so that the heat of the heating plate 208 is external. Should not be released. By attaching the heat insulator 214 to prevent heat loss, energy efficiency can be further increased.

The heat insulating material 214 of the microwave oven according to the present invention may form an outer wall of the cooking chamber 202 by using an insulating material, or may be used by attaching an insulating plate made of an insulating material to the surface of the existing cooking chamber outer wall.

The microwave oven according to the present invention installs heating plates on each of the inner surfaces of the cooking chamber so that the food is heated evenly, so that the user can obtain even cooking results without changing the location of the food.
