In general, an over-the-range microwave oven (OTR) is installed above a gas oven range or an electric oven range, and is generated in a gas oven range or an electric oven range to produce heat as well as directed upward. There is an exhaust function for exhausting a gas or the like containing food particles generated in the air to the outside. A hood-use microwave oven having such an exhaust function usually has a structure in which an exhaust motor is installed just below its upper surface, more specifically just below its rear end, in order to perform this function.

Such a microwave oven has a structure that has an exhaust motor cover to change the exhaust direction of the exhaust motor to the front, top or rear of the hood microwave oven just above the exhaust motor installation place. The exhaust motor cover is sufficiently detachable without being expert in the art, and is usually configured in such a manner that the exhaust motor cover is tightly fixed by one or more screws while being fitted to a part of the outer case of the microwave oven. .

However, such an exhaust motor cover is not only manufactured separately through a separate manufacturing process, but also an exhaust motor cover manufactured separately in this manner must be fastened by one or more screws to be fitted to a part of the microwave oven outer case for a hood. It was a waste of time.

A, B, C and D: Connection

In order to achieve the above object, the present invention,

An exhaust motor cover on one side of which a first fastening protrusion having a fastening hole is formed and at least two second inserting protrusions formed on the other side thereof; And

The exhaust motor cover and two or more parts are integrally formed, and when the exhaust motor cover is rotated by 180 ° about the surface center axis of the exhaust motor cover, the fastening hole coaxial with the fastening hole of the first fastening protrusion is inherently formed. Provided is an exhaust motor cover integrated structure including an outer case formed on the second insertion protrusion side and having a first insertion hole formed on the first fastening protrusion side to allow the first insertion hole to be coupled to the second insertion protrusion.

In addition, according to the present invention, there is provided at least one exhaust damper assembly that can be assembled by receiving the exhaust damper inside the exhaust motor cover.

As mentioned above, the integrated structure of the hood-only microwave oven outer case and the exhaust motor cover according to the present invention can be manufactured in an integrated structure of the hood-only microwave oven outer case and the exhaust motor cover in only one process. As a result, the cost and time are reduced compared to the conventional two or more processes.

Hereinafter, with reference to the accompanying drawings will be described in detail the integrated structure of the exhaust motor cover according to a non-limiting embodiment of the present invention.

1 shows a structure in which the hood-only microwave oven outer case 30 and the exhaust motor cover 20 are integrated, and in FIG. 2, the exhaust motor cover 20 is formed from the hood-only microwave oven outer case 30. It is shown that a part of the component is inserted and fastened to the microwave oven outer case 30 in a state of being separated and rotated 180 °.
