Description

Technical Field

[0001] The invention belongs to the field of integrated stoves, and in particular relates to a silent integrated stove and a method for using the silent structure thereof. Background Art

[0002] Integrated stoves, also known as environmentally friendly stoves or integrated environmentally friendly stoves in the industry, are kitchen appliances that integrate multiple functions such as range hoods, gas stoves, disinfection cabinets, and storage cabinets. They have the advantages of saving space, good fume extraction effect, energy saving, low consumption, and environmental protection. The general integrated stove has an oil absorption rate of 95%. The higher the oil fume absorption rate, the better the quality. Some brands of integrated stoves have an oil fume absorption rate of 99.95%. The integrated stove uses the principle of micro-aerodynamics, deep well down-discharge or side suction down-discharge, and the principle of the negative pressure zone of the fluid generated by the down-discharge, so that the oil fume can be sucked down like magic, and the phenomenon of oil fume rising everywhere can no longer be seen. The oil fume absorption rate is more than 95%. The integrated stove is an internationally leading kitchen appliance product developed to solve the problem that traditional range hoods cannot completely eradicate oil fumes and improve the kitchen and home environment. The product organically combines range hoods, stoves, disinfection cabinets, storage cabinets, etc. to completely eradicate kitchen oil fumes.

[0003] The range hood is an important part of the integrated stove. It absorbs the kitchen fumes through the fan. In actual use, the fan will make a loud noise after working, part of which is produced by the fan working and the other part is produced by the collision of air flow. These sounds produce high decibel noise, which is easy to cause discomfort to users. Summary of the invention
