Installation method of refrigeration range hood and kitchen refrigeration range hood

Abstract

The invention discloses a refrigeration range hood and a mounting method for the kitchen refrigeration range hood. The refrigeration range hood comprises an indoor unit, a cooking fume module and a controller. The indoor unit comprises an air inlet, an air outlet, a refrigeration air flue communicating with the air inlet and the air outlet, and a first draught fan arranged inside the refrigeration air flue. The cooking fume module comprises a fume exhaust air flue communicating with a fume collecting cavity, and a first draught fan arranged inside the fume exhaust air flue. The controller is electrically connected with the first draught fan and the second draught fan, and used for reducing the operation gear of the first draught fan when it is detected that the second draught fan is in high-gear operation. The refrigeration range hood is high in cooperation degree of refrigeration and fume exhaust, and good in overall refrigeration or fume exhaust effect.

Description

technical field [0001] The invention relates to the technical field of oil fume extraction equipment, in particular to a refrigeration range hood and an installation method for a kitchen refrigeration range hood. Background technique [0002] In order to improve the sultry working environment in the kitchen and save kitchen space, an existing solution is to adopt a refrigerating range hood that can simultaneously extract oil fume and refrigerate. [0003] The air inlet and outlet of the existing refrigerating range hoods for cooling are relatively close to the lower end of the refrigerating range hood. In this way, a negative pressure adjacent to the smoke collection cavity or a cold air curtain adjacent to the smoke collection cavity will be formed during cooling and air supply. At the same time, due to the independent control of the cooling fan for cooling and air supply and the smoke exhaust fan for extracting oil fume, when both the cooling hood and the smoke exhaust fan...

AI Technical Summary

Problems solved by technology

[0004] 1. If the air inlet of the refrigeration is adjacent to the smoke collection chamber, the negative pressure formed at the air inlet and the negative pressure formed in the smoke collection chamber will have a mutual weakening effect, and cause part of the oil fume to enter the cooling air duct;

[0005] 2. If the cooling air outlet is adjacent to the smoke collection chamber, the air curtain formed by the cold wind blown from the air outlet will hinder the air flow to the smoke collection chamber, and at the same time, part of the cold air will be discharged outside through the smoke collection chamber without fully mixing with the air for heat exchange;

[0006] Therefore, the existing refrigerating range hoods are prone to the problems of poor cooling effect and / or poor smoke exhaust effect under some working conditions
