In addition, a plurality of grooves groove 422 are formed on the side plate 420s forming both side surfaces of the oven cavity 410. The groove 422 is formed so that the rack (424) for supporting the food can be mounted so that the food can be cooked at an appropriate position when cooking the food, and can be variously applied according to the size and type of food. Various types of grooves 422 and racks 424 are formed.

On the other hand, with reference to Figures 7 and 8 will be described in more detail the coupling of the upper heater as follows.

The heater support 460 is installed below the upper plate 420u, and the upper heater 430 is mounted below the heater support 460. A plurality of heater accommodating grooves 462 recessed upward is formed on a lower surface of the heater support 460.

The heater accommodating groove 462 is for accommodating the upper heater 430 and is formed somewhat larger than the diameter of the upper heater 430. In addition, the heater receiving groove 462 is formed in the same shape as the shape of the upper heater 430 so that the entire upper heater 430 can be accommodated inside the heater receiving groove 462.

In addition, a plurality of exhaust holes 464 are formed in the upper end portion of the heater accommodation groove 462, that is, the protruding portion of the heater accommodation groove 462 along the shape of the heater accommodation groove 462. The exhaust hole 464 is a passage through which the exhaust gas inside the oven cavity 410 moves, and is discharged through the exhaust hole 464 after the exhaust gas is burned by the upper heater 430.

Hereinafter, the operation of the oven unit of the electric oven range according to the present invention having the configuration as described above.

A user opens the oven door 600, puts food in the oven cavity 410, and closes the oven door 600 to seal the oven cavity 410. When the oven cavity 410 is sealed, the operation knob 340 of the controller 300 is operated to operate the heaters inside the oven cavity 410.

The interior of the oven cavity 410 is heated by the operation of the upper heater 430, the lower heater 440 and the convection heater 450, the convection fan 452 formed on the rear of the oven cavity 410 As a result, tropical flow occurs more smoothly inside the oven cavity 410. Foods are cooked evenly by the action of the heaters 430, 440, 450 and the convection pan 452.

When food is heated in the oven cavity 410 at high temperature heat, harmful gases such as carbon monoxide are generated in the food, and these harmful gases are continuously generated during cooking and filled inside the oven cavity 410.

On the other hand, the flow of the exhaust gas containing the harmful gas filled in the oven unit 400 will be described with reference to FIG.

The noxious gas filled in the oven cavity 410 flows into the space spaced apart from the upper heater 430 and the heater accommodation groove 462 formed by the heater accommodation groove 462 and the fixing bracket 470. The gas is burned and decomposed by the high temperature heat generated by the upper heater 430.

In addition, the exhaust gas combusted by the upper heater 430 to remove noxious gas flows into the heater support 460 by the exhaust hole 464. The exhaust gas introduced into the heater support 460 passes through the exhaust port 420u 'formed at one side of the upper plate 420u and is guided by the vent tube 700 and discharged to the lower side of the control unit 300. do.

On the other hand, the outlet direction of the vent tube 700 may be formed to the rear or upward of the control unit 300, if necessary, exhaust gas in which noxious gas is burned without the vent tube 700, the top burner unit It may be possible to exhaust the air through a natural gap formed between the 200 and the controller 300 or between the top burner 200 and the oven 400.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, in the present invention, the heater support 460 is configured to shield the entirety of the upper plate 420u, but the heater support 460 is configured to shield a part of the upper plate 420u as necessary. It would be possible.

In this case, the shape of the heater accommodating groove 462 formed in the heater support 460 may also be available in various shapes, unlike the shape of the upper heater 430.

As described in detail above, the oven exhaust structure of the electric oven range according to the present invention burns exhaust gas generated in the oven cavity by heat generated from the upper heater without a filter device and discharges the exhaust gas upward through the exhaust hole. You have a configuration.

Therefore, the harmful gas can be removed by forming the heater support with the exhaust hole without complicated assembly work such as connecting the filter device and the vent tube during the manufacturing process of the product, thereby simplifying the assembly work. There is an effect to be improved.

In addition, it is relatively difficult to assemble, and by constructing an electric oven range having a sufficient harmful gas removal effect without applying a costly filter device will have a significant effect of reducing the production cost.

In addition, since the use of the harmful gas removal method using the heat of the upper heater is possible to use permanently, there is an effect of inducing user satisfaction because no additional maintenance cost occurs.
