Fire-resistant safety range hood

Abstract

The invention discloses a refractory safe kitchen ventilator. The kitchen ventilator comprises a cone-shaped soot collecting hood, an electric motor, a transmission shaft, fan blades, a refractory fire-proof plate, a soot discharging cylinder, suspensions, a protective cabinet, a first bearing, a second bearing, a transmission shaft, a first bevel gear, a third bearing and a second bevel gear. The kitchen ventilator disclosed by the invention is simple and reasonable in structure; the maintenance workload for clearing oil dirt is greatly reduced, and the fire resistance and the safety performance of the kitchen ventilator are significantly improved.

Description

technical field [0001] The invention belongs to the improvement of the structure of oil fume suction and exhaust equipment, in particular to a fire-resistant safety range hood. Background technique [0002] Although various existing oil fume suction and exhaust devices are becoming more and more perfect, and the oil fume suction and exhaust effect is good, the oil fume will still adhere to the motor and other electromechanical components that are traditionally installed in the fume collection hood of the oil fume suction and exhaust device during the process of being sucked and exhausted. In addition, in general, when the cooking oil in the frying pan below the fume collecting hood catches fire, its flame rushes upwards into the fume collecting hood cavity and burns the oil fume suction and exhaust device, and even causes a fire. Therefore, the structure of the existing oil fume suction and exhaust device is too complicated and unreasonable, the workload of grease removal an...

Problems solved by technology

[0002] Although various existing oil fume suction and exhaust devices are becoming more and more perfect, and the oil fume suction and exhaust effect is good, the oil fume will still adhere to the motor and other electromechanical components that are traditionally installed in the fume collection hood of the oil fume suction and exhaust device during the process of being sucked and exhausted. In addition, under normal circumstances, when the cooking oil in the frying pan under the fume collecting hood catches fire, its flame rushes upward into the chamber of the fume collecting hood and burns the oil fume suction and exhaust device, even causing a fire

Therefore, the structure of the existing oil fume suction and exhaust device is too complex and unreasonable, the workload of grease removal and maintenance is heavy, and the fire resistance (fire prevention) performance is deviated
