Hereinafter, with reference to Figure 4 with respect to the air flow inside a preferred embodiment of the hood-use microwave oven according to the present invention configured as described above.

First, the airflow for cooling the electric parts of a microwave oven is demonstrated.

When the cooling fan 57 installed in the electric compartment 54 of the microwave oven is driven, the indoor air is sucked into the inside of the microwave oven through an air vent 52 'formed at the upper end of the front of the cavity assembly 50. The indoor air sucked in this way forms an air flow circulating through the electric compartment 54 by the continuous driving of the cooling fan 57.

The airflow cools the various electrical components installed in the electrical equipment chamber 54 while circulating the electrical equipment chamber 54. And it is introduced into the cooking chamber through a through hole 54 ′ formed at one side of the electrical equipment room 54 so as to communicate with a cooking chamber (not shown) of the microwave oven.                     

Next, the airflow for the hood function will be described.

In the process of cooking food in the gas range 80, smoke including heat and odor is generated. In addition, such smoke includes things such as smell of food and heat, and the air flow introduced into the microwave oven by driving the vent pan assembly 61 of the microwave oven installed above the gas range 80. To form.

The airflow formed by driving the vent fan assembly 61 flows into the inside of the microwave oven, that is, the suction flow path 65 through the suction port 58 'provided in the base plate 58 of the microwave oven. In addition, the airflow flows to the vent pan assembly 61 through the suction passage 65.

When the vent pan assembly 61 is continuously driven, the airflow flows into the inlet of the vent pan assembly 61 and flows into the discharge passage 67 through the outlet of the vent pan assembly 61. The airflow flows along the discharge passage 67 and is discharged into the room through the vent grill 75 provided at the tip thereof.

By the way, since the louver 77 of the vent grill 75 is installed to be inclined downward, the airflow discharged into the room through the vent grill 75 is inclined downward toward the bottom of the microwave oven. Therefore, the airflow is sucked back into the microwave oven through the suction port 58 'together with the new smoke generated in the gas range 80 by the operation of the vent pan assembly 61.

In addition, as described above, the airflow discharged through the vent grill 75 is sucked back through the suction inlet 58 ′, thereby forming a kind of air curtain. Therefore, the phenomenon that the smoke generated in the gas range 80 by the air flow is not sucked into the microwave oven through the suction port 58 ′ and spreads to the indoor space is prevented.

On the other hand, as shown in Figure 4, a part of the airflow may not flow into the interior of the microwave oven can be spread to the indoor space to contaminate the indoor air. However, such a phenomenon can be prevented or minimized by adjusting the inclination and shape of the louver 77.

According to the present invention as described above, it can be seen that the basic technical idea is to install the vent pan assembly for the hood function on the bottom of the electronic lane.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the above teachings. will be.

According to the hood-use microwave oven by this invention comprised in this way, the following effects are anticipated.

First, by minimizing the length of the flow path for the hood function, the flow resistance is reduced to improve the hood performance, and the volume of a space such as a cooking chamber or an electrical equipment room can be relatively increased in a microwave oven of a certain size.

In addition, the smoke generated in the process of cooking food in the cooker installed below the microwave oven can be spread to the indoor space to minimize the phenomenon of contaminating the indoor air.
