Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] see Figure 1 ~ Figure 3 , a range hood, comprising a smoke collection hood 1, a chassis 2 arranged above the fume collection hood 1, a fan system 4 is arranged in the chassis 2. An air inlet 11 is provided on the fume collecting hood 1, so that the fan system 4 in the cabinet 2 can suck oily fume into the cabinet 2 through the air inlet 11 and discharge it to the public flue.

[0027] An air duct 25 is formed in the cabinet, and the air duct 25 is preferably gradually narrowed from bottom to top.

[0028] In this embodiment, the blower system 4 is a three-way blower, and the three-way blower can adopt the existing technology, as disclosed in the Chinese patent application number 201310418009.X. The fan system 4 can be a single ternary fan, two parallel ternary fans or two series ternary fans. Since the ternary fan has the characteris...

Abstract

The invention discloses a range hood. The range hood comprises a cooking fume collection hood, a case arranged above the cooking fume collection hood, and a cooking fume filter device. An air inlet isformed in the cooking fume collection hood. A duct is formed in the case. The cooking fume filter device comprises an oil screen arranged at the air inlet. The whole oil screen is in the shape of a cone which becomes smaller from top to bottom and extends downwards from the air inlet. The range hood is characterized in that the cooking fume filter device further comprises a rotary filter screen arranged in the case and located at an inlet of the duct. The oil screen and the rotary filter screen are arranged, the oil screen can rectify and guide the air flow, and the air flow can evenly distributed at the air inlet through the rotary filter screen; and through the combination of the oil screen and the rotary filter screen, effective rectification and guidance of the air flow can be achieved, turbulent currents and disordered currents in the air flow are reduced, the air flow is made smooth, and vortexes formed before the air flow enters a fan system are reduced.

Description

technical field [0001] The invention relates to kitchen appliances, in particular to a range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and near-suction types. Top-suction range hoods use the principle of rising hot air to absorb and discharge the naturally rising oil fumes generated during cooking. It has more and more widespread applications. [0003] The oil fume filter device is an important component of the range hood, and the technical improvement of the oil fume filter device has always been a technical hotspot in the range hood field. Existing range hoods are equipped with filter screens for the purpose of collecting oil fumes and dust generated during cooking, such as a range hood disclosed in Chinese Patent Application No. As well as the box and the fan assembly, the oil receiving box is set under the oil filter screen, and the oil fume is ...
