Disclosed herein is a range hood having improved sound characteristics by improving a structure thereof. The range hood includes a case including an inlet through which air is introduced, and a fan module arranged inside the case to suck air through the inlet. The fan module includes a fan configured to move air by rotating, a motor configured to supply a driving force to rotate the fan, a fan frame provided to accommodate the fan and the motor therein, the fan frame including a fan inlet and a fan outlet, and a sound generating member provided to generate a sound of a predetermined frequency band when in contact with the air discharged through the fan outlet.

A portable hood may include a base, a head, a column, and a roll filter unit. The roll filter unit may include a purification filter installed in the head and discharged to an outside of the head after moving past a suction inlet. Accordingly, one of purification filters, for example, an oil mist filter, may be provided as a roll filter, so cleanliness, maintenance, and replacement of the filter is easy.

An air duct which extends substantially in a longitudinal direction (X), having a duct wall which encloses a flow cross section and has, on its inner side, at least one fastening means for fastening at least one functional element, which can be accommodated in the air duct, in a variable position in the longitudinal direction (X) of the duct.

A hob (1) with one or more cooking locations (2), which, as viewed from above, exhibits one or more recesses (4) only in the area (25) around its geometric center (3), which are respectively connected with one or more devices (5) for removing cooking vapors through suction. These devices (5) for removing cooking vapors through suction downwardly remove the cooking vapors that arise above the cooking locations (2) by suction in a direction vertically below the hob (1), and such a hob (1), which in the assembly unit is designed with a device (36) for operating the hob (2) and downwardly removing cooking vapors by suction.

The present invention discloses a panel mechanism of a range hood. The range hood comprises a left side plate (3), a right side plate (4), and a plurality of hanging pieces (5); the panel mechanism comprising a panel (1) and a panel frame (2), the panel frame (2) comprises a center plate (20), a left hanging bar (21), a right hanging bar (22) and a support bar (26), the left hanging bar (21) and the right hanging bar (22) has a plurality of hanging slots (23,24), each hanging slot (23,24) engages one hanging piece (5); the first hanging slot (23) is bent backward from the top to the down; and the second hanging slot (24) is sloped backward from the top to the down; the opening of each of the first hanging slot (23) and the second hanging slot (24) is bigger than the inner end of the first hanging slot (23) and the second hanging slot (24), enabling the first hanging slot (23) and the second hanging slot (24) to be hung on the corresponding hanging pieces (5) more easily. Therefore, it is easy for assembly and disassembly.

A fume extraction device for installation in an item of kitchen furniture includes an air duct, a top side provided with an air inlet opening, an appliance housing arranged below the air inlet opening and having a side wall provided with an air outlet opening which is connected to the air duct, a fan arranged in the appliance housing, and a noise filter element received in the appliance housing and including a filter material which is chemically inert.

Disclosed is a range hood, including: a case provided with a smoke inlet; and a fan provided inside the case. An air inlet area is formed between an air inlet of the fan and a side wall of the case, the air inlet area is provided with a spacer, and the spacer is configured to divide the air inlet area into at least two air inlet sub-areas. The air inlet sub-areas are located at different positions of the air inlet area. The airflow entering the case from the smoke inlet flows to the air inlet of the fan, and the airflow flows to the sub-air inlet area in different directions. The space blocks airflows in different directions, to prevent turbulence at the intersection of airflows in different directions.
