Microwave oven having hood < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a microwave oven, and more particularly, to a microwave oven combined with a hood for easy fastening of a lamp.

Microwave ovens are one of the cooking appliances that heat and cook food by means of heat emitted from a high frequency and / or a heater called a microwave. The microwave oven is provided with a magnetron which irradiates an internal space of a cooking chamber, which is a space in which a high frequency is oscillated by a supplied power source to cook food.

The microwave oven shields a cooking chamber for providing a cooking space for food and then irradiates a high frequency generated from the magnetron to an internal space of the shielded cooking chamber to cook food by heating the food.

Also, in recent years, various heating sources have been installed for quick and efficient cooking of food. Such a heating source includes a magnetron, a heater for heating the shielded cooking chamber by radiating heat by supplied electricity, and the like.

As described above, various heat sources are installed, so that the food can be cooked more quickly, and various foods can be cooked.

In this way, various heating sources are installed to shorten the cooking time and cook various foods by heating the food, but in order to cool various heating sources and a plurality of electric parts, the flow of cooling air must be accompanied .

Among these microwave ovens, a microwave oven having a hood function is collectively referred to as a microwave oven combined with a hood or an over-range type microwave oven. The hood combination microwave oven performs a hood function of sucking and discharging air containing exhaust gas generated in the course of cooking food in another cooking device provided below.

Therefore, the hood-use microwave oven further includes an air flow path for a hood function, and has an air flow path different from a general microwave oven. That is, the hood suction flow path for suctioning the exhaust gas in the external space and the hood exhaust flow path for exhausting the suctioned exhaust gas are further included.

The present invention proposes a hood-use microwave oven in which an exhaust duct is installed to facilitate service.

In the present invention, a hood combined microwave oven which facilitates assembly of a lamp is proposed.

A microwave oven combined with a hood according to the present invention comprises: a body forming an outer appearance; An upper plate which divides an internal space of the main body into an upper space and a lower space; A blowing fan located in an inner space of the main body to flow air; An exhaust duct for separating a space through which air flows into the outer space of the main body by the blowing fan and a space where the electrical parts are installed in the upper space; A duct cover made of a flame retardant material in the exhaust duct; A lamp positioned in an inner space of the exhaust duct to emit light; And a lamp support for supporting the lamp; .

According to the present invention as described above, it is possible to expect an easy effect of fastening the lamp for lighting the cooking chamber. As the fastening of the lamp is facilitated, the assemblability of the product is improved and the productivity of the product is improved.

In addition, since the cover of the exhaust duct is made of a flame retardant material, safety can be expected to be improved. When the flame-retardant cover is removed, services such as lamps and other electric parts can be provided, . ≪ / RTI >

Further, since the weight of the exhaust duct is reduced, it is possible to reduce the cost, and the weight of the exhaust duct can be reduced, thereby reducing the cost of transporting the product.

When the lamp 85 is fixed by the lamp support portion 88 and the duct cover 81, the lamp 85 can be fixed without being fastened by other fastening members.

The upper space 70 is formed with a space for air to move through the vent grill 77.

The upper plate (15) is provided with an exhaust port (19). The air outlet (19) serves as an outlet through which air is discharged to the outside of the cooking chamber (30).

Inside the body 10, a side plate 17 and a lower plate 18 are provided. The side plates (17) form both sides of the cooking chamber (30). The left side of the side plate 17 in the drawing forms a flow path through which the combustion gas of the other cooking device flows between the side plate 17 and the upper panel 13. Further, among the side plates 17, the right side in the figure substantially defines the cooking chamber 30 and the electric field chamber 40.

The lower plate (18) forms the bottom surface of the cooking chamber (30) and the electric field chamber (40). This lower plate 18 is parallel to the upper plate 15. A lower end of the side plate 17 is fixed to the upper surface of the lower plate 18.

The duct cover 81 may be fixed to the exhaust duct 80 by means of fasteners or the like to shield the installation opening 80a. The duct cover 81 may be made of a material having a predetermined strength, for example, a metal material.

Meanwhile, the exhaust duct 80 is provided with a separating member 87. The separating member 87 divides the space between the upper plate 15 and the exhaust duct 80 into two spaces. At this time, the two spaces partitioned by the separating member 87 are communicated with the installation opening 80a.

Further, a part of the separating member is exposed above the exhaust duct 80 through the installation opening 80a.

A plurality of parts are provided on the upper plate 15 corresponding to a space between the upper plate 15 and the exhaust duct 80 and substantially below the exhaust duct 80. In this embodiment, the stirrer device and the lamp 85 are located in the space between the upper plate 15 and the exhaust duct 80.

At this time, the stirrer device and the lamp 85 are positioned in the spaces defined by the separating member 87, respectively. That is, the stirrer device is located in the space on the right side of the figure partitioned by the separating member 87, and the lamp 85 is located in the left space in the drawing among the spaces partitioned by the separating member 87 . Therefore, the lamp 85 can be exposed to the upper side of the exhaust duct 80 through the installation opening 80a.

More specifically, the stirrer device diffusively reflects high-frequency waves radiated to the inside of the cooking chamber 30. The stirrer device includes a stirrer cover 83 which forms a predetermined space communicating with the cooking chamber 30, a stirrer cover 83 which is installed inside the stirrer cover 83 and rotates for diffused reflection of high frequency And a stirrer fan motor 82 installed outside the stirrer cover 83 and providing a driving force for driving the stirrer fan.

In this state, the duct cover 81 is fixed to the exhaust duct 80 to shield the installation opening 81a. When the duct cover 81 is fixed to the exhaust duct 80, one side of the supporting portion 85a is brought into close contact with the bottom surface of the duct cover 81. [ Accordingly, upward movement of the lamp 85 is restricted, and the installation of the lamp 85 is completed.

Meanwhile, when the lamp 85 needs to be replaced or repaired, the lamp 85 is separated from the lamp 85 in the reverse order of the installation of the lamp 85 described above. That is, first, the duct cover 81 is separated from the exhaust duct 80 to open the installation opening 81a. Then, the lamp 85 is taken out through the installation opening 81a.

The lamp 85 can be replaced or repaired by removing only the duct cover 81 by opening and closing the space where the lamp 85 is located by the duct cover 81, Assemblability, and productivity are improved.
