The present invention provides an exhaust and cooling device for a wall-mounted microwave oven, and more particularly, a cooling device capable of cooling an exhaust device and an overheating component by sucking steam containing oil or dust generated during food cooking and discharging it to the outside. A device for exhausting and cooling a wall-mounted microwave oven integrally formed with a device.

In general, a wall-mounted microwave oven is widely used in homes because of the efficient cooking and simplicity of cooking. Especially, a wall-mounted microwave oven is installed at the top of an electric or gas stove at home to exhaust smoke or steam generated during cooking to the outside. A wall-mounted microwave oven equipped with

U. S. Patent No. 4,786, 774 shows a wall-mounted microwave oven equipped with the exhaust device and the cooling device as described above. The exhaust device has a fan blade 1a connected to the upper and lower sides of the suction port and the wall-mounted microwave oven formed on the bottom plate. By installing a blower (1) consisting of a fan motor (1b) to connect the blower pipes (2) connecting them between the left and right sides of the wall-mounted microwave oven is a structure in which air is sucked from the bottom and discharged to the top.

In addition, the cooling device has a suction port 6 formed in the upper part of the apparatus chamber so that relatively cool air is introduced by the cooling fan installed in the apparatus chamber 9, and the apparatus is cooled after the high pressure transformer and the magnetron installed in the apparatus chamber 9 are cooled. After cooling the turntable motor driving the discharge port 5 formed at the top of the chamber 9 and the turntable 21 installed in the cooking chamber 3, the discharge port 8 and the inside of the cooking chamber 3 formed at the upper part of the cooking chamber 3 are cooled. Through the discharge port 7 formed in the upper end of the cooking chamber 3 through.

However, as the blower used to suck smoke or steam to the top is located at the top of the microwave and a powerful force is required to exhaust the air from the bottom to the top, the blower's rotational speed is increased and thereby occurs in the fan motor. There was a problem that the noise is increased by the vibration.

In addition, the above-described cooling device has a problem in that only the components of the apparatus chamber and the turntable motor for driving the turntable of the cooking chamber are cooled, but the overheat generated in the blower cannot be cooled.

The present invention has been made to solve the above-mentioned conventional problems, by improving the exhaust device and the cooling device installed in the wall-mounted microwave oven to cool the parts of the equipment room, turntable motor and blower by the air sucked by the cooling device. It is also an object of the present invention to provide an exhaust and cooling device for a wall-mounted microwave oven configured to allow the blower to operate stably.

The object of the present invention is to install the blower used in the exhaust device in the lower part of the wall-mounted microwave oven to discharge the air to the top and the air flowing into the inside of the wall-mounted microwave oven by the operation of the cooling fan installed in the equipment room It is configured to prevent the overheat by applying the air to the blower by forming a discharge port on the bottom surface of the device chamber that is in contact with the blower to improve the position of the discharge port to be discharged to the blower part of the air cooling the overheated parts of the equipment room It features.

Hereinafter, the exhaust and cooling device of the wall-mounted microwave oven of the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view showing the exhaust and cooling device of the wall-mounted microwave oven according to an embodiment of the present invention, the exhaust device for introducing the air containing oil or dust to the outside to discharge the overheating of the components operated by the operation of the microwave oven. It consists of a cooling device for cooling.
