Embedded microwave oven having novel draught structure of electric fitting chamber

Abstract

The invention discloses an embedded microwave oven having a novel draught structure of an electric fitting chamber. The embedded microwave oven comprises a cavity, wherein a cooking chamber is formed in the cavity; the cooking chamber is communicated with the exterior of the microwave oven; the electric fitting chamber is arranged in the right cavity of the cooking chamber; the electric fitting chamber is communicated with the cooking chamber and communicated with the exterior of the microwave oven; an intermediate partition plate is arranged on the upper part of the electric fitting chamber; an electric fitting chamber cooling fan is arranged at the opening of the intermediate partition plate; a hollow draught cover is arranged below the electric fitting chamber cooling fan; an opening is formed at a position, corresponding to the electric fitting chamber cooling fan, of the top of the draught cover; the opening is correspondingly formed at one end, toward the direction of the cooking chamber, of the draught cover; and the opening is also formed at the bottom of the draught cover. By the draught cover of the microwave oven, the cooling fan can cool all electronic parts which are positioned below the cooling fan, so a cooling effect is achieved, air in the whole electric fitting chamber can be introduced into the cooking chamber at the same time, and water vapor which is generated by cooking foods is effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of microwave ovens, in particular to an embedded microwave oven with a novel structure for introducing air into an electric equipment room. Background technique [0002] A microwave oven is a device that generates microwaves from an electric current and irradiates the microwaves to the surface of the object to be heated in the cavity to heat the object. As everyone knows, microwave oven is a kind of modern cooking stove that heats food with microwave. The microwave it uses is a kind of electromagnetic wave. The energy of this electromagnetic wave is not only much greater than that of ordinary radio waves, but also has special characteristics. When the microwave hits metal, it will reflect, and the metal has no way to absorb or conduct it; microwave can pass through insulation such as glass, ceramics, and plastics. Materials, but will not consume energy; and food containing water, not only can not pass thro...

Problems solved by technology

The high-voltage transformer 8 and the magnetron 9 are wrapped in the air-introduction hood, and the air-induction hood is only open at both ends and the rest is sealed. Specifically, the opening at one end communicates with the cooling fan 17, and the opening at the other end communicates with the cooking chamber 4. Therefore, the cooling fan 17 that the existing embedded microwave oven has only blows the air sucked from the outside of the microwave oven to the high-voltage transformer 8 and the magnetron 9, and then directly blows to the cooking chamber 4, so that the electric equipment chamber cannot be directly blown. Other electronic parts (such as high-voltage capacitor 10) in 5 are cooled down, and this air-introduction hood is only opened at two ends, can only introduce the air that flows through high-voltage transformer 8 and magnetron 9, the air volume that the air-induction hood inhales Small, which seriously affects the air volume flowing into the cooking chamber 4, and cannot guarantee that the air blown from the electrical equipment chamber 5 into the cooking chamber 4 has enough wind force to effectively remove the water vapor produced by cooking food, thus affecting the food quality. cooking effect
