Embodiment Construction

[0035]The present invention will be further described in detail below with reference to the accompanying drawings embodiments.

[0036]Such asFigure 1 to 11As shown, the suction hood includes a smoke shield 5 and a fan system, wherein the fan system includes a windforce 1, a fan 11, an air outlet plate 12, a first driving assembly 3, and a first drive assembly 3. The second drive assembly 4.

[0037]Such asfigure 2 ,image 3 ,Figure 5 ,Figure 8 andFigure 9 As shown, the set of smoking hoisting holes 5 is connected to the bottom of the fan frame 1, and the smoking cover 5 is provided with an inducing port 51 in which the inner phase fluid in the windforce 1 is provided.

[0038]Such asimage 3 ,Figure 5 andFigure 9 As shown, the fan 11 is provided in the windforce 1, in the natural state, the fan 11 is tilted backwards from top to bottom. The foregoing fan 11 includes a volute 111 and an impeller 112 disposed in the volute 111, and the rotation axis of the impeller 112 is gradually inclined upw...

Abstract

The invention relates to a fan system and a range hood applying the fan system. The fan system comprises a fan frame and a fan, wherein the fan is arranged in the fan frame, and comprises a volute and an impeller; an air inlet and an air outlet are formed in the volute; and vent holes are formed in an air outlet plate. The fan system is characterized in that the front side edge or the rear side edge of the air outlet plate is rotationally connected with the fan frame; the air outlet plate is connected with the fan frame through a first driving assembly which can enable at least part of the air outlet plate to move up and down relative to the fan frame; and the volute is connected with the air outlet plate through a second driving assembly capable of enabling the volute to move back and forth relative to the air outlet plate. The distance and the inclination angle between the air inlet of the volute and the relative vertical wall plate of the fan frame can be adjusted and changed according to actual working conditions, so that the situation that local loss of the air outlet is increased due to the fact that the inclination angle is too large is avoided, the fan efficiency is improved, and the problem that noise is increased due to the fact that the inclination angle is too small is solved.

Description

Technical field[0001]The present invention relates to the technical field of suction hood, and more particularly to a fan system and an oil-proof smoke applied to the fan system.Background technique[0002]The oil hood has become one of the indispensable kitchen home appliances in modern families. The oil-hhoto machine is to operate with fluid kinetic principles, and the crankshaving fans inside the suction hood are used to use the filter filter section. Grease particles. The centrifugal fan includes a volute, an impeller mounted in a volute and a motor that drives the impeller. When the impeller is rotated, a negative pressure suction is generated in the center of the fan, and the fumes below the suction hood are suck in the fan. After the fan is accelerated, it is collected by the volute, and the discharge is guided outdoor.[0003]The existing suction hood wind turbine system is fixed to the top rear plate assembly or the winder assembly, in order to meet the rising trajectory of the...
