Energy-saving environment-friendly side-draft type range hood

Abstract

The invention relates to an energy-saving environment-friendly side-draft type range hood. The energy-saving environment-friendly side-draft type range hood comprises an exhaust smoke collecting hood with an air inlet and a fan system arranged behind the exhaust smoke collecting hood, wherein the air inlet is communicated with the fan system, a smoke deflector is arranged in front of the air inlet, and a smoke collecting cavity is formed by a gap between the exhaust smoke collecting hood and the smoke deflector; the energy-saving environment-friendly side-draft type range hood is characterized in that a top plate is arranged above the exhaust smoke collecting hood, an upwardly-concave smoke collecting cushion chamber is formed in the top plate, the smoke collecting cushion chamber is communicated with the smoke collecting cavity, the volume of the smoke collecting cushion chamber is 2-12L, and the maximum air-suction volume per second of the range hood is 150-350L / s. The energy-saving environment-friendly side-draft type range hood can achieve good oil smoke suction and energy-saving and environment-friendly effects without reducing the oil smoke separation degree or increasing the motor power.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to an energy-saving and environment-friendly side suction range hood. Background technique [0002] Current side draft hoods, such as figure 1 , including a smoke collection hood with an air inlet, a fan system behind the smoke collection hood, the air inlet is connected to the fan system, a smoke guide plate is arranged in front of the air inlet, and the gap between the smoke collection hood and the smoke guide plate forms a smoke collection cavity, There is a top plate above the smoke collecting hood. The top plate of the current side suction range hood is horizontal. The oil fume rises to the top plate and enters the smoke collecting chamber from the gap between the smoke guide plate and the top plate. Spillage, especially when a large amount of oily fume rises, such as the moment when the dish is put into the pot during cooking, the instantaneous amount of oily fume exceeds the m...

AI Technical Summary

Problems solved by technology

The gap between the smoke guide plate and the top plate is increased to make the oil fume enter the smoke collection chamber faster, but this design reduces the area of ​​the smoke guide plate, reduces the separation effect of grease, and affects the environmental protection of the oil fume discharged outside. The flat roof still cannot effectively prevent the oil fume from overflowing; increasing the width of the roof can only prevent the oil fume from overflowing from the front of the roof to a certain extent, but it cannot reduce the oil fume overflowing from the left and right sides of the roof, and even after increasing the width of the roof, a large amount of oil fume It is located under the flat top plate, which instead leads to an increase in the amount of oil fume overflowing from the left and right sides. Neither of these two methods can achieve a better oil fume inhalation effect; and increasing the motor power of the range hood can better achieve oil fume discharge. However, the cost of this method is relatively high, and if the power of the motor is increased in order to expel a large amount of oily fume generated instantly, the higher motor power will cause waste of energy during the time period when relatively little oily fume is generated during the cooking process, which is not energy-saving and environmentally friendly.
