Near-suction range hood

Abstract

The invention discloses a near-suction range hood. The near-suction range hood comprises a shell, a cabinet and a fan system, wherein the cabinet and the fan system are located above the shell. The shell comprises a panel which is located at the front end and is inclined to the horizontal direction. The near-suction range hood is characterized in that the fan system comprises a first three-elementfan and a second three-element fan which are arranged in parallel; the fan system is arranged in the cabinet, at least two smoke guide plates are arranged on the front side of the panel, and the smoke guide plates are arranged on the front side of the panel and are arranged side by side in the left-right direction at intervals; an air inlet channel is formed by gaps between the smoke guide platesand the panel and gaps between adjacent smoke guide plates; and at least one of the smoke guide plates can stretch relative to the panel so as to be close to the panel to close the air inlet channelor be away from the panel to open the air inlet channel. At least two smoke guide plates which are arranged side by side and are arranged at intervals are arranged on the front side of the panel, so that airflow passing through an outer rectifying layer can be effectively segmented, rectified and guided, turbulent flow and turbulence in the airflow are reduced, and smooth airflow is formed.

Description

technical field [0001] The invention relates to kitchen appliances, in particular to a near-suction 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 range hoods. Near-suction range hoods use vortex wind pressure to move away, and absorb most of the fumes that are close to the stove in an arc, which can reduce adverse effects on human health. Influence, and the power source is closer to the stove, basically it will not reduce the suction effect of the power source. [0003] For example, the Chinese patent application number 201320064301.1 discloses a highly efficient and environmentally friendly side suction range hood, which includes a deflector with an air inlet and a fan system behind the deflector. A top plate is arranged above the plate, and a smoke baffle is arranged in front of the air inlet. The gap between the deflector and th...

Problems solved by technology

[0004] As mentioned above in the prior art, the negative pressure area is small, and the negative pressure distribution on the air inlet surface is uneven. After the oil fume enters the smoke collection chamber, it is easy to cause turbulence and turbulent flow, which affects the efficiency of oil suction fume, and the deflector plate is difficult to Clean; the fan system usually uses a multi-blade centrifugal fan, and the multi-blade centrifugal fan is placed in the lower triangle. In order to ensure a high air intake efficiency, the fan system is relatively large

Moreover, this arrangement of the fan, because the impeller has a pre-rotation effect on the gas and the direction of the gas will gradually change during the 90° turning process of the gas flowing into the impeller, the purely consistent inlet and outlet angles are not good for the actual working ability of the impeller. ;In addition, the fan is far away from the air outlet pipe, it is difficult to overcome the resistance of the pipe, the fan faces the user directly, lacks noise reduction measures, and the noise is high
