Embodiment 1

[0048] see Figure 1 to Figure 4 As shown, this embodiment provides a smoke collection hood assembly, including a cover body 20 , a filter screen 10 and a suction assembly 30 ; the filter screen 10 can be fixed in the cover body 20 through the suction assembly 30 .

[0049] In the smoke collecting hood assembly provided in this embodiment, the filter screen 10 is fixed in the cover body 20 by the suction assembly 30, which can prevent the filter screen 10 from loosening.

[0050]Further, the cover body 20 is used to be installed at the air inlet of the air duct system, and the cover body 20 is provided with an air inlet passage 201 communicated with the air outlet of the air duct system; the filter screen 10 is slidably connected in the air inlet passage 201; The net 10 is in a state of sliding balance as the air permeability of the filter net 10 changes.

[0051] When in use, the cover body 20 is installed on the air outlet of the air duct system of the range hood, and when ...

Embodiment 2

[0082] see Figure 5 with Image 6 As shown, this embodiment also provides a fume collection hood assembly, the fume collection hood assembly of this embodiment is an improvement on the basis of the first embodiment, and the technical solutions of the first embodiment also belong to this implementation For example, the description will not be repeated here. The same components use the same reference numerals as in the first embodiment, and reference is made to the description of the first embodiment.

[0083] In this embodiment, the smoke collecting hood assembly further includes an elastic member 53 , and the elastic member 53 is located between the filter screen 10 and the cover body 20 .

[0084] One end of the elastic member 53 is fixedly connected to the guide column 52 , and the other end of the elastic member 53 is fixedly connected to the cover body 20 . The elastic force of the elastic member 53 is designed to be greater than the suction force of the air duct syste...

Embodiment 3

[0087]This embodiment also provides a range hood, including the fume collecting hood assembly provided in Embodiment 1 of the present invention.

[0088] The range hood provided in this embodiment may be a top suction range hood or a side suction range hood.

[0089] Further, the suction assembly 30 and the switch assembly 40 are respectively connected with the main controller of the range hood.

[0090] Further, the main controller of the range hood is set to a constant current working mode to generate a constant air volume, thereby generating a constant negative pressure.

[0091] Further, when the filter screen 10 triggers the switch assembly 40 , the main controller of the range hood sends a message that the filter screen 10 needs to be replaced. For example, the range hood can also be provided with corresponding display lights or alarms, so as to remind customers to replace the filter screen 10 .

[0092] Further, the air duct system of the range hood is provided with a...

Abstract

The invention provides an exhaust fume collecting hood assembly and a range hood, and relates to the technical field of household appliances. The exhaust fume collecting hood assembly provided by the invention comprises a hood body, a filter screen and a suction assembly; and the filter screen can be fixed in the hood body through the suction assembly. The filter screen is fixed in the hood body through the suction assembly, and the filter screen can be prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a smoke collecting hood assembly and a range hood. Background technique [0002] The oil fume of the existing range hood is filtered through the filter screen arranged at the air inlet. Usually, the filter screen is generally a metal oil screen, and the filter screen is usually placed at the air inlet. After the oil fume is separated, the filter screen filters a part. The impeller, air duct and the inner wall of the body filter part. During use, the existing filter screen is easy to loosen, resulting in poor oil fume filtering effect. In addition, when the oil on the filter screen accumulates to a certain extent, the filter screen will be blocked by the oil stain and cannot continue to absorb oil fumes. At this time, the user needs to replace or clean the filter screen. If the user has no time to replace or clean the filter screen, it will affect the use and bring ba...
