Ventilation structure for over the range

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven for hood, and more particularly, to an exhaust structure for discharging exhaust gas from the bottom of the hood for microwave oven to the outside using a back plate structure installed at the rear of the electric compartment.

In general, a microwave oven with a hood refers to a microwave oven having an exhaust function for exhausting heat and smoke generated in the gas oven range in addition to the cooking function which is a function of the microwave oven.

1 is a perspective view showing the internal structure of a common hood microwave oven.

As shown, the microwave oven 1 is formed in the cavity assembly 2 in the cavity assembly 2 and the cooking chamber S, which is a space for heating and cooking food, and the side of the cooking chamber S. The located electrical room E is formed.

The electrical equipment chamber (E) has built-in components for supplying microwaves, which are heating sources for heating food. That is, the electric chamber E is equipped with a magnetron 22 for oscillating microwaves, and a high voltage transformer 24 for raising the voltage in order to apply a high voltage to the magnetron 22.

In the upper part of the electric compartment E, a cooling fan 18 is installed in order to prevent high temperature heat generated by microwaves being activated and the microwave oven is operated. If the heat of the magnetron 22 and the high-pressure transformer 24, etc. are not radiated, the reliability of the parts is adversely affected, and thus, the electrical component of the electrical chamber is cooled in order to prevent them.

A bottom plate 10 is formed at a lower portion of the electrical equipment room E, and a bottom plate 10 extending rearward is installed, and a base plate 12 is installed below a predetermined interval of the bottom plate 10.

The base plate 12 is formed with an inlet (not shown) through which heat and smoke generated from the gas oven range are sucked.

The space between the bottom plate 10 and the base plate 12 has an exhaust passage 11 through which heat and smoke generated in the gas oven range pass, which is a characteristic of a microwave oven with a hood.

On the other hand, the rear exhaust duct 15 which communicates with the exhaust passage 11 and passes through the exhaust passage 11 to the exhaust motor assembly 35 at the rear end of the electric compartment E is a back plate 14 and an air guide. It is formed between (16). That is, the vent plate 13 is formed in a section in which the bottom plate 10 extends to the rear of the electric compartment E, so that the exhaust gas on the exhaust passage 11 can escape to the rear exhaust duct 15. It is configured to be.

The back plate 14 is installed perpendicular to the base plate 12 to form a rear surface of the electric chamber E, and is combined with a rear mounting plate 14 ′ to form a rear wall of the microwave oven.

In addition, the air guide 16 is formed at a predetermined interval on the front surface of the back plate 14, the space in which the electrical components of the electrical equipment room (E) is installed and the space where the rear exhaust duct 15 is formed. Compartment.

Next, an air flow formed in the exhaust chamber exhaust duct according to the related art according to FIG. 2 will be described. As shown, the exhaust gas generated in the gas oven range (not shown) of the lower portion of the microwave oven is introduced into the bottom of the microwave oven through the inlet (not shown) of the base plate 12, the base plate ( 14) and through the exhaust passage 11 between the bottom plate 10 to the rear end of the lower part of the electrical equipment room (E), and again through the vent 13 formed in the bottom plate 10 of the rear end of the electrical equipment room (E) After flowing into the rear exhaust duct 15 formed between the air guide 16 and the back plate 14, the ascend to the exhaust motor assembly 35 installed in the upper part of the electric chamber E and discharged to the exhaust port 36. It can be seen that airflow is formed.

In the conventional structure, however, the exhaust gas is guided to the upper side of the exhaust fan, and a separate air guide is manufactured to partition the space where the electrical components of the electrical equipment are installed and the rear exhaust duct. Due to the configuration of the air guide, the components of the microwave oven are increased, the production cost is increased, as well as the assembly process is complicated, there is a problem in that the productivity is a problem.

The present invention has been made to solve the above problems, an object of the present invention is to form a rear exhaust structure of the electric compartment simply by configuring a rear exhaust duct without an air guide.
