Displacement configuration of range hood and range hood

Abstract

The invention relates to a displacement configuration of a range hood, which comprises an impeller, an annular connecting member and a net disk, wherein the net disk is connected with the impeller bythe connecting member and comprises a framework coaxially arranged with the impeller and meshes arranged on the framework and used for intercepting oil drops, a circle of oil guide structure enclosingthe meshes is arranged on the connecting member, and the oil guide structure comprises an oil guide slot and an oil discharge hole communicated with the oil guide hole and used for discharging oil inthe oil guide slot. The invention also relates to a range hood configured with the displacement configuration of the range hood. According to the displacement configuration, due to the arrangement ofthe oil guide slot, oil drops on the meshes can be collected and are prevented from flowing to the center of the net disk, and due to the collection effect of the oil guide slot, oil drops dischargedfrom the oil discharge hole is large in mass, and therefore, the oil drops can fly along a straight line more easily and fall into an already arranged oil collecting device, and the problem that relatively small oil drops fly apart towards the inside of the impeller due to wind effect is avoided.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to an oil discharge structure of a range hood and the range hood. Background technique [0002] The range hood is one of the commonly used kitchen appliances. Its function is to "suck away" the smoke generated by cooking during cooking, also known as smoke separation, so as to reduce the spread of smoke in the indoor air and external emissions. When cooking produces a large amount of oil droplets splashing to the suction port of the range hood, the ideal state is that the range hood can suck these oil droplets into the range hood and separate the oil droplets and collect them in the oil tank. When the oil accumulates to a certain amount, The user pours out the waste oil, and so on. The actual range hood products, due to the current functional limitations, most of them suck oil droplets into the fan, and the oil droplets will stick to the inside of the fan or the impeller, which fi...

Problems solved by technology

The grid disk can intercept oil droplets. Theoretically, under the action of centrifugal force, the oil droplets intercepted by the grid disk will be thrown into the oil collection ring located on the outer peripheral side of the grid disk under the action of centrifugal force. However, when the machine is shut down or the impeller running speed changes suddenly At this time, the oil intercepted on the grid plate will spread out in an irregular track along the edge of the grid plate or flow into the impeller along the intermediate shaft, or flow to the lower end of the grid plate under the action of gravity, and enter the range hood shell, resulting in secondary Pollution
