摘要： A microwave oven includes a cooking chamber in which either microwave cooking or hot air convection cooking can be performed. A cooling chamber is situated rearwardly of the cooking chamber for housing a motor and cooling fan. A rear cover of the cooling chamber includes air intake and air exhaust holes formed therein for circulating a cooling air flow produced by the fan. The cover includes a vertical central surface in which the air intake holes are formed, as well as additional surfaces extending obliquely forwardly from respective edges of the central surface. The additional surfaces include a top surface, a bottom surface, and right and left side surfaces. Each of those additional surfaces, except for one of the side surfaces, includes air exhaust holes. Each of the air exhaust holes includes a rearward projection extending thereabove to resist the entry of water. Each of the air intake holes includes a projection extending forwardly from an edge thereof and inclined toward a central axis of the air exhaust hole to resist the entry of foreign objects. A rearward protrusion formed on the central surface serves to space the air intake openings from a surface located adjacent to the microwave oven.
摘要翻译：微波炉包括可以进行微波烹饪或热空气对流烹饪的烹饪室。冷却室位于烹饪室的后方，用于容纳电动机和冷却风扇。冷却室的后盖包括形成在其中的进气和排气孔，用于使由风扇产生的冷却空气流循环。盖子包括垂直的中心表面，其中形成有进气孔，以及从中心表面的相应边缘向前倾斜延伸的附加表面。附加表面包括顶表面，底表面和左右侧表面。除了一个侧表面之外，这些附加表面中的每一个包括排气孔。每个排气孔包括在其上方延伸以抵抗水进入的向后突出部。每个进气孔包括从其边缘向前延伸并且朝向排气孔的中心轴线倾斜以防止异物进入的突起。形成在中心表面上的向后突起用于将进气口与位于微波炉附近的表面间隔开。

摘要： A microwave oven capable of quickly detecting the abnormal operation and the overheated temperature of a high voltage transformer. The microwave oven including cooking chamber, a magnetron configured to provide a high frequency wave to inside of the cooking chamber, a high voltage transformer (HVT) including a core, a primary coil wound around the core, and a secondary coil wound around the core and configured to transform a voltage, which is provided to the microwave oven, to the magnetron, and a Thermo Protector (TP) configured to block a current from being applied to the primary coil when the HVT is overheated, wherein the TP is disposed at an outer surface of the secondary coil.

摘要： A microwave oven cooks in a microwave cooking mode using a magnetron, or in an oven cooking mode using a convection heater. A passage is provided for conducting outside air to the cooking chamber, and a fan is disposed in the passage for inducing the outside air flow. During the oven cooking mode, the convection heater is activated and the fan is deactivated, while the temperature in the cooking chamber is less than a reference temperature set by a user. When the temperature in the cooking chamber exceeds the reference temperature, the heater is deactivated, and the fan is activated.
