Micro-wave oven air discharging electric motor units possessing oil smoke suction function

Abstract

The invention discloses a microwave furnace exhaust motor set with function of absorbing oil smoke, comprising a motor, motor shafts, exhaust fans, and wind scoopers. The motor generates drive force when a power source is connected; the motor shafts are respectively connected with two sides of the motor and are rotated by the drive of the motor; the exhaust fans are respectively connected with the two sides of the motor and are rotated by the rotation of the motor shaft; and the wind scoopers are respectively connected with the two sides of the motor, and the wind scoopers of the exhaust fans are used for guiding air current when the exhaust fans are rotated, and at least one axial fan is arranged in the exhaust fans. The microwave furnace exhaust motor set can obviously improve cooling effect of electric appliance parts of a magnetron and so on which are arranged inside an electric appliance room of a microwave furnace, and effectively prevent corrosion of the electric appliance parts, thereby prolonging service life of the electric appliance parts, lightening weight of the integral exhaust motor set, and reducing manufacturing cost at the same time.

Description

technical field [0001] The invention relates to a microwave oven, in particular to an exhaust motor unit of the microwave oven with the function of absorbing oil fume. Background technique [0002] Microwave ovens with both the function of absorbing oil fume are usually installed on the upper side of the gas stove in the kitchen, and have the function of discharging gas such as oil fume and water vapor generated when the gas stove is used for cooking. [0003] figure 1 It is a schematic diagram of the air flow of the microwave oven with the function of absorbing oil fume in the prior art; figure 2 It is a perspective view of the prior art exhaust motor unit. [0004] like figure 1 and figure 2 As shown, an exhaust motor unit 20 is provided on the upper side of the cooking chamber 10 of the microwave oven 1 with the function of absorbing oil fume. The exhaust motor unit 20 is provided with centrifugal fans 22 and 24 on both sides, and the centrifugal fans 22 and 24 are...

Problems solved by technology

[0006] As mentioned above, the air flowing in from the air inlets 14a, 14b contains smoke, water vapor, etc. generated when cooking with a gas stove, so before entering the interior of the microwave oven 1, its temperature is already higher than that of the outside air. Therefore, when the air dissipates heat to the electrical components such as the magnetron inside the electrical appliance chamber 22, the cooling effect is not ideal.

At the same time, components such as smoke and water vapor contained in the air are likely to corrode the electrical components such as the magnetron inside the electrical room 22 and shorten the service life of these components, thus reducing the credibility of the customer on the product as a whole.

[0007] Moreover, the centrifugal fan used in the prior art is relatively bulky, heavy, and expensive, so the manufacturing cost of the exhaust motor unit also increases.
