1 is a perspective view showing an appearance of an oven range of the present invention. FIG. 2 is a photograph for measuring the temperature distribution around the oven part in the case where the duct unit is not provided for comparison with the present invention. 3 is an exploded perspective view of the duct unit of the present invention. 4 is an assembled perspective view of the duct unit of the present invention. 5 is a side cross-sectional view showing the air flow of the duct unit of the present invention. 1 to 5, the structure and operation of the duct unit and the oven range equipped with the duct unit of the present invention will be described.

The oven range includes a free standing type in which the side cover 230 is exposed to the outside and a free standing type in which the side cover 230 on both sides of the oven range is installed in the kitchen furniture 10 and a built-in type built-in type. For example, in the built-in type oven range, the installation of the side cover 230 may be omitted. When the side cover 230 is not provided, heat is accumulated in the side surface of the cavity 210 and the empty space formed by the kitchen furniture 10, and this heat is discharged to the outside by the duct unit of the present invention.

The oven range of the present invention is a hybrid type that can be used for two types of built-in type or free standing type depending on whether or not the oven range is embedded in the kitchen furniture 10 indicated by the virtual line in Fig.

The oven range includes an oven unit 200 for indirectly heating foods into convection heat for baking, baking, and barbecue cooking, and a cooktop unit 100 provided above the oven unit 200 to directly heat the cooking utensil .

Examples of a heat source for heating the oven part 200 include an electric heater, a microwave, a gas flame, and the like. The oven part 200 includes a cavity 210, a door 212, and a side cover 230. At this time, a top panel 220 covering the upper side of the cavity 210 may be further provided.

The cavity 210 serving as a food cooking space is opened and closed by a door 212 and a rack 216 for loading food is installed inside the cavity 210. The inside of the cavity 210 is preferably coated with enamel or other enamel for easy cleaning. The rack 216 is movably supported along the guide member 215 formed in the cavity 210 in the direction of the door 212. By drawing the rack 216, the food is put into the cavity 210 or the cooked food is taken out. The side cover 230 forms an enclosure of the oven range. When the heat insulating material 240 is interposed between the side cover 230 and the cavity 210, the heat of the cavity 210 is blocked from being transmitted to the surroundings. It is preferable to provide the duct unit of the present invention as a more active measure against overheating to prevent overheating.

On the upper surface of the cook top part 100, a heating element 110 is provided to heat the cooking utensil. As the kind of the heating element 110, a gas burner, an electric heater, a far-infrared heater, a microwave, or the like may be used.

The cook top part 100 is provided with a controller 120 for displaying a user menu and controlling the overall operation of the oven range. The controller 120 senses the temperature inside the cavity 210 and the degree of ripening of the food, controls the oven 200 so that no food is burned, and displays various menus and operation states to allow the user to select a desired menu A timer function, and a self-cleaning function for automatically cleaning the inside of the cavity 210. The control unit 210 performs various control functions, such as a display of a remaining column for displaying remaining columns, a reservation function, a timer function, The controller 120 is provided in the form of a PCB equipped with a microprocessor.

On the other hand, when heat is concentrated in a specific area of the oven range, there is a possibility that the controller 120 which is particularly sensitive to static electricity or heat may malfunction or break. Particularly, when the self-clean mode for burning dirt and odors inside the cavity 210 by burning is carried out, the cavity 210 is raised to a high temperature, so that the heat concentration phenomenon becomes conspicuous. In addition, when the oven range is installed as a built-in type, an oven range is installed in the closed space of the kitchen furniture 10, so that the cooling efficiency deteriorates and hot spots may occur in the oven range, May be overheated to, for example, 90 DEG C or higher.

Such an overheating phenomenon can be suppressed by covering the upper side and the side surface of the cavity 210 with the heat insulating material 240. The present invention is not limited to this but includes a duct unit as a means for more actively shielding heat transmitted to the kitchen furniture 10 and the side cover 230 or the controller 120 adjacent thereto.

Particularly, since the oven range of the present invention is a hybrid type which can also serve as a freestanding type and a built-in type, it is preferable that the controller 120 is provided on the upper side of the oven part 200 and on the front side of the cooktop part 100. Accordingly, the duct unit has a structure capable of concentrating circulation of the air in the upper part of the oven part 200, which is the position where the controller 120 is provided, so that heat is not concentrated. The front direction is defined as a direction toward the door 212 and the rear direction is defined as a direction toward a rear wall inside the cavity 210. [

On the other hand, when the oven range of the present invention is installed in the free standing type, air around the oven part 200 can be circulated by natural convection through the empty space between the side cover 230 and the oven part 200. However, when the oven range of the present invention is installed in a built-in type, sufficient natural convection can not be obtained. Accordingly, since the controller 120 or the side cover 230 is likely to overheat, the cooling fan 250 and the duct unit are provided to forcibly circulate air to prevent overheating.

Referring to the temperature distribution photograph shown in FIG. 2, a portion having a high temperature is indicated in red. When the duct unit of the present invention is not provided, a hot spot is formed in red on the upper side of the oven unit 200. Heat is concentrated on the upper part of the oven part 200 due to heat generation of the cavity 210, and more particularly, heat is concentrated on the entire upper side of the oven part 200. This is because air circulation around the cavity 210 is not smooth on the upper side of the oven part 200, particularly on the upper side of the oven part 200. The temperature of the upper part of the oven part 200 is higher than that of the oven part 200 due to the rise of the hot air, This can be caused by the fact that the front surface is formed with a small amount of empty space for air flow.

1, 3, and 4, the duct unit includes an intake duct 270, an exhaust duct 260, and a cooling fan 250. Here, it is preferable that the duct unit further includes a front slot 130 and an upper slot 223.

When the heat insulating material 240 is provided on the side surface of the cavity 210, the heat is accumulated in the space between the heat insulating material 240 and the side cover 230.

Such heat is discharged to the outside by the duct unit. The duct unit sucks the heat accumulated in the inner space of the side cover 230 and discharges the heat to the outside of the oven unit 200 to thereby suppress the generation of hot spots on the upper side of the side cover 230. When the oven range is built- Thereby preventing the temperature of the furniture 10 from rising.

The intake duct 270 sucks the heat accumulated in the side surface of the cavity 210 and the inner space formed by the side cover 230 and is disposed on the upper surface of the exhaust duct 260 and is disposed on the front surface of the intake duct 270 272 preferably have a sufficient width to cover the top surface slot 223. [

The exhaust duct 260 is located above the cavity 210 as a passage for air connecting the cooling fan 250 and the front slot 130. When the upper panel 220 is provided on the upper side of the cavity 210 and the heat insulating material 240 is interposed between the upper side of the cavity 210 and the upper panel 220, the exhaust duct 260 is disposed on the upper panel 220 Located. The exhaust duct 260 discharges the heat inside the side cover 230 flowing through the rear face 273 of the intake duct 270 to the outside of the oven part 200 through the front slot 130.

The front slot 130 is an air flow passage formed on the upper side of the door 212 and communicates with the front surface 262 of the exhaust duct 260 to discharge the heat to the outside.

The upper surface slot 223 is a passage through which the heat of the inner space of the side cover 230 is drawn into the intake duct 270 and is provided at both side edges of the upper panel 220 covering the upper side of the cavity 210. It is necessary to concentrate the flow of the air in this portion in order to concentrate the upper surface of the controller 120 and the upper surface of the oven part 200 where the hot spot is located so that the upper surface slot 223 is locally formed on the front surface of both side edges of the upper panel 220 .

Although not shown in the drawings, when the upper surface slot 223 is formed over the entire length of both side edges of the upper panel 220, the upper surface slot 223, which is located on the front surface of the oven part 200, The length, and the width of the intake duct 270 are designed so that the intake duct 270 can be covered. Accordingly, the flow of air is concentrated on the entire upper side of the side cover 230 to prevent the occurrence of the hot spot and the overheating of the controller 120.

That is, irrespective of whether or not the top surface slot 223 is formed over part of both side edges of the top panel 220 or both side edges of the top panel 220, the total length d in the depth direction of the oven part 200 It is preferable that intake of the intake duct 270 is performed through the upper surface slot 223 disposed at the front side of the oven part 200 from a point where the intake duct 270 is half.

The cooling fan 250 is disposed on the rear surface of the intake duct 270 and rotates to generate an air flow force. The rear surface of the cooling fan 250 and the intake duct 270 are connected by a cooling fan hole 253.

Although not shown, the controller 120 senses the concentration of heat around the oven part 200 through the side cover 230, the inside of the cavity 210, the upper side of the cavity 210, The hot spot is intensively cooled as shown in Fig.
