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

Embodiment 1

[0039] like Figure 1-2 As shown, in order to discharge the oil droplets intercepted on the network disk 2 in a relatively regular manner, the technical solution adopted in this embodiment is that an oil guide structure 4 is also provided on the network disk 2, and the oil guide structure 4 is arranged along the The radial distribution of the mesh disk 2 is on the periphery of the mesh wire 22. The oil guide structure 4 includes an annular oil guide groove 41 and is arranged on the side of the oil guide groove 41 away from the axis of the mesh disk 2 to discharge the oil in the oil guide groove 41. A plurality of oil discharge ports 42, the oil discharge ports 42 are evenly distributed along the circumferential direction of the grid plate 2.

[0040] Specifically, the oil guide groove 41 is an annular groove arranged on the outer edge of the grid plate 2 and recessed toward the impeller 1 along the axial direction of the grid plate 2, and the oil discharge port 42 extends from...

Embodiment 2

[0048] like image 3 As shown, the difference between this embodiment and Embodiment 1 is that the oil discharge port 42 is a straight outlet, specifically, the oil discharge port 42 is parallel to The direction of the bottom surface runs through the side wall of the oil guide groove 41, and the oil discharge port 42 is a straight outlet, which can achieve a better effect of discharging oil droplets.

Embodiment 3

[0050] like Figure 4-7 As shown, in order to discharge the oil droplets intercepted on the grid plate 2 in a more regular manner, the technical solution adopted in this embodiment is that the oil discharge structure of the present invention also includes an annular connecting piece 3, on the connecting piece 3 Also be provided with the oil guide structure 4 that surrounds mesh wire 22 in a circle, described oil guide structure 4 comprises oil guide groove 41 and is arranged on the side of oil guide groove 41 far away from grid disk 2 axle centers and is used for the oil in oil guide groove 41 discharges. There are four oil discharge ports 42, and the oil discharge ports 42 are evenly distributed along the circumferential direction of the grid plate 2. The outer peripheral side of the mesh disk 2 is connected to the inner peripheral side of the front end of the impeller 1 through a connecting piece 3 . The oil guide groove 41 is an annular groove arranged on the end face of t...

Abstract

The invention relates to a kitchen ventilator oil discharge structure. The kitchen ventilator oil discharge structure comprises an impeller and a mesh disc arranged on the front side of the impeller;the mesh disc comprises a skeleton which is coaxially arranged with the impeller and mesh wires which are arranged on the skeleton and used for intercepting oil drops, a ring of an oil guiding structure is arranged on the mesh disc and located at the periphery of the mesh wires, and the oil guiding structure comprises an annular oil guiding groove and oil discharge outlets which communicate with the oil guiding groove and used for discharging oil in the oil guiding groove. The invention further relates to a kitchen ventilator with the kitchen ventilator oil discharge structure. According to the kitchen ventilator oil discharge structure, the oil drops on the mesh wires can be collected by arranging the oil guiding groove, the condition that the oil drops flow to the center of the mesh discis avoided, the mass of the oil drops discharged out of the oil discharge outlets is large through the collecting effect of the oil guiding groove, therefore, the oil drops can fly along a straight line more easily and fall into an arranged oil collecting device, and the problem that small oil drops fly into the impeller due to the influence of wind power after being tossed out can be 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...
