Exhaust apparatus for ventilation hood micro-wave oven

Abstract

The invention discloses a ventilation hood micro-wave oven exhausting equipment, it includes regulating room, which is used to regulate food, and outer box hood, a exhausting passage is formed between the room and the hood, a space part with laminas, is formed between the outer bottom of the regulating room and the under box lid of outer box hood. The lamina space provides big caliber centre of a circle lamia, which sends the air, absorbed from under box lid, into exhausting pipe. Within the microwave oven standard, the invention sets big caliber centre of a circle lamia around the air absorbing port, reduces air absorbing resistance, increases air absorbing quantity. The plate, which is used to absorb outer air, is a big caliber absorbing plate, the quality of absorbing / exhausting is increased, it can achieve air absorbing and exhausting even at 800rpm, which is more lower than traditional speed, so the noise of ventilation hood is decreased.

Description

Technical field [0001] The present invention relates to a microwave oven equipped with a vent hood capable of exhausting polluted air in the room (kitchen) on the microwave oven. More specifically, it relates to a microwave oven that can reduce the air inhalation resistance and achieve the minimum noise of the vent hood. Exhaust device for microwave ovens for ventilation hoods that fully inhale and exhaust air. Background technique [0002] Generally speaking, a microwave oven for a fume hood is usually installed on the upper side wall of a gas stove in a home kitchen, and it is a household appliance that performs a function of ventilating the indoor air while conditioning by microwave. [0003] Combine below figure 1 , A brief introduction to the general setting state of this kind of ventilated microwave oven. [0004] Such as figure 1 As shown, the microwave oven 1 for a fume hood is arranged on the upper side wall surface 3 of the gas stove 2 in the home kitchen, and the ven...

AI Technical Summary

Problems solved by technology

[0016] But, adopt the microwave oven of conventional technology because the suction force that two suction exhaust blades 13 produce makes air from the long, curved exhaust passage 22 that product interior forms to suck in, and the exhaust volume that is discharged from air discharge port 19a Compared with the air suction port 20a, the suction volume sucked in is less, so when the two suction and exhaust vanes 13 are rotated at high speed (about 3200rpm) in order to increase the suction volume, there will be serious flow noise and motor noise due to the disk.
