Microwave oven

Abstract

A microwave oven effectively and uniformly cooks large-sized food even though the food inhibits a proper rotation of a cooking tray in a cooking cavity of the microwave oven. An upper wave dispersing unit is provided at a top wall of the cooking cavity and primarily disperses microwaves from the top wall into the cooking cavity. A side wave dispersing unit is provided at a second sidewall of the cooking cavity opposite to a first sidewall of the cooking cavity. The first sidewall partitions the cooking cavity from a machine room of the microwave oven. The side wave dispersing unit secondarily disperses the primarily dispersed microwaves in the cooking cavity. The second sidewall of the cooking cavity has a recess which receives a fan of the side wave dispersing unit. A cover is installed in front of the recess to cover the fan of the side wave dispersing unit. The cover is made of a transparent material and allows a user to view a rotational operation of the side wave dispersing unit.

Description

technical field

[0001] The present invention relates to a microwave oven, and in particular, to a microwave oven capable of uniformly cooking food placed on a cooking tray in a cooking chamber of the microwave oven even when the cooking tray is not rotating. Background technique

[0002] Generally speaking, a microwave oven is an electrically driven oven that uses high-frequency electromagnetic waves to heat and / or cook food contained in its cooking chamber. The high-frequency electromagnetic waves are generated by the oscillation of a magnetron placed in the equipment compartment of the microwave oven. That is, during a cooking operation, the magnetron installed in the equipment chamber radiates the high-frequency electromagnetic waves (microwaves), passing through the cooking chamber. These microwaves pass through the food, repeatedly changing the arrangement of the moisture molecules contained in the food, causing the moisture molecules to vibrate, generating frictional ...
