Problems solved by technology

[0004] Existing range hoods have a single driving mode for the impeller, and the impeller is driven by an electric motor to generate negative pressure to exhaust the oil fume.
It can even be said that this driving mode of driving the impeller by the electric motor has become a common-sense technical means in the field, and those of ordinary skill in the field involved in the present invention have no motivation to seek new impellers without creative work.

Embodiment 1

[0037] The present invention provides an embodiment of a range hood, which includes a fan assembly, a smoke collecting hood, a casing and a filtering device.

[0038] The fan assembly of this range hood embodiment includes a motor module and a housing part 4, such as Figures 1 to 4 shown. The motor module includes a rotor unit and a stator unit. The casing part 4 is fixed in the casing, and the casing part 4 is a hollow cylindrical structure. The rotor unit is arranged inside the casing part 4 , and the stator unit is arranged outside the casing part 4 .

[0039] The rotor unit includes a plurality of permanent magnets (not shown in the figure) and an impeller, and each permanent magnet is fixed on the impeller. Each permanent magnet is evenly arranged around the axis of the impeller. The impeller rotates around the axis of the impeller to generate negative pressure to extract oil fume. It can be seen that the impeller of the range hood for exhausting oil fume is also us...

Embodiment 2

[0046] The present invention also proposes another embodiment 2 of the range hood, which is further improved on the basis of the above embodiment 1 of the range hood. The main differences between the second embodiment of the range hood and the first embodiment of the range hood are as follows.

[0047] The range hood embodiment 2 adopts a fan assembly with a different structure. The fan assembly used in Embodiment 2 of the range hood includes a protective cover 10, a first plate body 12, a second plate body 13, a motor module and a housing part 4, such as Figures 5 to 7 shown. What needs to be explained here is that in order to facilitate the display of related structures, Figure 7 The housing part 4 is shown with the wall at one side of the housing part 4 removed, and the protective cover 10 is also not installed.

[0048]The motor module includes a rotor unit and a stator unit. The rotor unit is arranged inside the casing part 4 , and the stator unit is arranged outsid...

The draught fan assembly of the smoke ventilator comprises impellers and also comprises a motor module; the motor module comprises a rotor unit and a stator unit; and the impeller is configured as a part of the rotor unit. The invention puts forward a new impeller driving mode.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of range hoods, in particular to the field of fan assemblies of range hoods. [0003] 【Background technique】 [0004] In existing range hoods, the driving mode of the impeller is very single, and the impeller is driven by an electric motor to generate negative pressure to exhaust the oil fume. It can even be said that this driving mode of driving the impeller by the electric motor has become a common-sense technical means in the field, and those of ordinary skill in the field involved in the present invention have no motivation to seek new impellers without creative work. Drive mode solution. [0005] References to prior art herein are not intended to be an admission that such prior art was known to those of ordinary skill in the art to which the present invention pertains prior to the filing date of this application, unless supported by sufficient evidence. [0006] 【Content of invention】 [0007] The main...
