Shell assembly of range hood and range hood

Abstract

The invention discloses a shell assembly of a range hood and the range hood. The range hood comprises a shell, a partition and a fan assembly, wherein an opening is formed in the front side of the shell; the partition is arranged in the shell, and divides the inside of the shell into a front side cavity and a rear side cavity which are arrayed in the front-to-back direction; a main air inlet is formed in the partition; at least one of the partition and the shell defines an auxiliary air inlet; the auxiliary air inlet is close to the edge of the partition; the air feeding end opening of the fan assembly is formed at the main air inlet and is communicated with the front side cavity; an auxiliary air opening is formed in the fan assembly; the main air inlet and the air feeding end opening define a main air duct; the auxiliary air opening and the auxiliary air inlet define an auxiliary air duct. According to the range hood disclosed by the invention, the shell assembly and the fan assembly are used for defining the main air duct and the auxiliary air duct, so that the lampblack catching capacity of the range hood can be improved, the air feeding efficiency is improved, and the air volume and the air pressure are increased; therefore, the lampblack absorption effect of the range hood can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of kitchen electrical equipment, in particular, to a shell assembly of a range hood and the range hood. Background technique [0002] With the improvement of people's health awareness, the range hood has gradually become an indispensable electrical appliance in every family. At present, the large air volume and suction power recognized by consumers has become the main selling point of the market, but the hood itself has the contradiction that the greater the air volume, the greater the noise. There are more and more complaints about noise in the market, and the industry has been looking for new noise reduction solutions. However, considering the system and structure of the range hood itself, it is very difficult to maintain low noise while maintaining a large air volume and high static pressure. things. The fan system is the core power system of the range hood, and the commonly used fan system is a...

AI Technical Summary

Problems solved by technology

This structure will greatly affect the distribution of the negative pressure area of ​​the main main air inlet, and then affect the effect of the main main air inlet on absorbing oil fume

On the other hand, the air intake from the lower side increases the flow path of the oil fume into the fan, which in turn increases the loss of the flow head

[0004] The lower main air inlet greatly affects the distribution of the negative pressure area of ​​the main main air inlet, which in turn affects the oil fume suction effect of the main main air inlet

Moreover, the air intake from the lower side increases the flow path of the oil fume into the fan, which in turn increases the flow pressure loss

On the other hand, for domestic hood users, there are basically two cookers and stoves under each range hood, and the lower side air intake scheme cannot well meet the needs of users

More importantly, the opening on the lower side will affect the appearance of the hood, and it is easy to cause oil dripping and oil leakage

In consideration of manufacturability, its complex structure, high cost, and complicated actual installation process are not conducive to mass production
