Description

a microwave oven

technical field

The utility model relates to a microwave oven, in particular to a microwave oven with a barbecue function, which belongs to the transformation technology of the microwave oven.

Background technique

Existing microwave ovens with barbecue function use heat pipes to heat food from top to bottom mainly through heat radiation. The disadvantage is that the temperature in the oven cavity rises slowly. On the top plate, close to the outer cover, part of the heat is transferred to the heating tube cover itself when the heating pipe is working, and this part of the heat can not contribute to heating food except that it causes the temperature of the outer cover near it to rise, resulting in waste.

Utility model content

The purpose of the utility model is to consider the above problems and provide a microwave oven that not only accelerates the temperature rise of the oven cavity, but also reduces the waste of heat to a certain extent, and lowers the temperature of the outer cover.

The technical scheme of the utility model is: a microwave oven, including a housing, a microwave generator, a heating pipe, a heating pipe cover, a heat shield, an air duct and a fan, wherein the heating pipe cover is installed on the top of the housing, and its Make a hollow cavity to accommodate the heat pipe, the heat pipe is installed in the hollow cavity made of the heat pipe cover, the heat shield is covered around the heat pipe cover, and the microwave generator and the fan are installed on one side of the shell correspondingly , which is characterized in that one end of the air duct is arranged corresponding to the microwave generator, the other end communicates with the heat shield, and the heat pipe cover communicates with the space surrounded by the heat shield through an opening or several holes.

Above-mentioned fan is microwave generator cooling fan, or special fan.

The utility model adopts a structure in which one end of the air guide pipe is correspondingly arranged with the microwave generator, and the other end communicates with the heat shield, and the heating pipe cover communicates with the space surrounded by the heat shield through the opening or several holes. Part of the front-blown wind passes through the microwave generator and is blown into the heat shield through the air guide pipe, and the heat on the surface of the heating pipe cover in the heat shield is brought into the furnace cavity through the holes on the heat pipe cover. Therefore, this utility model The new type can not only accelerate the temperature rise of the furnace cavity, but also provide cooling protection for the heating pipe and its surrounding parts, reduce the temperature requirements of the parts, and prolong their service life. The utility model is an ingenious design, simple structure, and low cost. , New microwave oven with good effect.
