Description

Technical Field

[0001] The utility model relates to the technical field of smoke machine equipment, and more specifically, to an oil slinger disc. Background Art

[0002] A range hood is an essential electrical appliance used to extract oil fumes during cooking in a kitchen or a canteen. With the gradual improvement of people's awareness of environmental protection and health, higher requirements are placed on the environmental protection indicators of range hoods. Among them, the oil separation degree of a range hood has become an important performance indicator to describe the range hood. The stronger the ability of the range hood to filter oil particles in the oil fumes, the higher the oil fume separation degree.

[0003] The dynamic shield of a range hood mainly consists of an oil slinger disc, a motor, and a housing. The exhaust gas leads to the oil slinger disc for the high-speed rotating range hood. The gas can pass through normally, but the oil particles will hit the oil slinger disc for the high-speed rotating range hood and be thrown out, achieving the effect of separating smoke and gas and purifying the environmental air. The conventional oil slinger disc has a straight plate structure, and its contact surface with the flue gas is too small, resulting in insufficient separation effect. This application improves the oil slinger disc to solve the problems of relatively low oil fume separation degree and oil removal rate of some existing range hoods. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an oil slinger disc to increase the collision contact area of oil fumes, facilitate the aggregation of oil particles to achieve oil fume separation, and thus improve the oil removal rate.

[0005] The embodiment of the utility model is realized by the following technical solutions: An oil slinger disc includes a central disc. An outer edge of the central disc is provided with first spokes and second spokes extending outward, and the first spokes and the second spokes are arranged alternately around the outer edge of the central disc; Drainage grooves are formed on both sides of the first spokes and the second spokes; At least two branch bars are provided at one end of the first spoke away from the central disc.

[0006] Further, it further includes a ring for connecting the first spokes and the second spokes, and the ring is coaxial with the central disc.

[0007] Further, the first spokes and the second spokes are arranged radially along the central disc.

[0008] Further, the branch bars are in a "Y" - shaped structure.

[0009] Further, a plurality of oil leakage notches are evenly formed on the central disc.

[0010] Further, arc - shaped convex heads are provided on side end faces of the first spokes and the second spokes, and the arc - shaped convex heads are provided at one end of the first spokes and the second spokes away from the central disc.

[0011] Further, a plurality of communication ports communicating with the oil drainage grooves are formed in the first spoke and the second spoke, and the communication ports are arranged alternately and staggeredly along both side edges of the oil drainage grooves.

[0012] Further, a plurality of oil blocking strips are formed on the side end faces of the first spoke and the second spoke.

[0013] Further, an extension edge strip is provided on one side end face of the first spoke and the second spoke.

[0014] The technical solution of the embodiment of the present utility model has at least the following advantages and beneficial effects: By providing oil drainage grooves on the spokes of the oil slinger, the increased number of groove sides increases the collision area of the oil fume;

[0015] And in cooperation with the oil blocking strips and communication ports on the side faces of the spokes, the flowing stroke of the oil fume is extended, the oil fume separation degree is higher, and the oil removal is more sufficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0028] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] Embodiment 1: Further illustrated below with specific Embodiment 1, referring to Figures 1 - 2 as shown, this embodiment is an oil slinger, including a center disc 1. An outwardly extending first spoke 2 and a second spoke 3 are provided on the outer edge of the center disc 1, and the first spoke 2 and the second spoke 3 are arranged alternately around the outer edge of the center disc 1; Oil drainage grooves 21 are provided on both sides of the first spoke 2 and the second spoke 3; At least two branch bars 22 are provided at one end of the first spoke 2 away from the center disc 1; Specifically, by providing the oil drainage grooves 21 on the first spoke 2 and the second spoke 3 of the oil slinger, when the oil slinger rotates driven by a motor, the collision area with the oil fume is increased, that is, the side surface of the oil drainage groove 21. The oil fume enters the oil drainage groove 21 to form a vortex, and can more effectively friction and collide with its inner wall, thereby aggregating on the surface, and then being thrown out along the oil drainage groove 21 by the centrifugal force of the oil slinger. The branch bars 22 further increase the oil fume contact surface, and at the same time, play a role in shunting when the oil fume is too heavy. Through the above structure, the oil fume separation effect and oil removal rate of the disc are improved.

[0030] Embodiment 1 further includes a ring 4 for connecting the first spoke 2 and the second spoke 3, and the ring 4 is coaxial with the central disk 1; specifically, by providing the ring 4, two-point connection is achieved to improve the strength at the outermost end and prevent the oil slinger from breaking due to excessive rotation speed.

[0031] It should be noted that the first spoke 2 and the second spoke 3 are arranged radially along the central disk 1.

[0032] As Figure 2 shown, the main body and the branch strip 22 of the first spoke 2 are in a "Y" shape structure, and its inclination angle is about 30°. Without affecting the oil-catching efficiency, the air resistance and noise are reduced.

[0033] As Figure 1 shown, a plurality of oil leakage slots 11 are evenly formed on the central disk 1, which are spaced around the middle part of the central disk 1. The oil leakage slots 11 are kidney-shaped holes through which the flue gas can pass, increasing the oil fume collision area.

[0034] Embodiment 2: Referring to Figure 3 and Figure 4 shown, based on Embodiment 1, the difference is that arc-shaped convex heads 5 are provided on the side end faces of the first spoke 2 and the second spoke 3, and the arc-shaped convex heads 5 are provided at one end of the first spoke 2 and the second spoke 3 away from the central disk 1; specifically, during the rotation of the oil slinger, the arc-shaped convex heads 5 at its outermost end can play a certain guiding role and increase the contact area of the oil fume flow.

[0035] As Figure 4 shown, a plurality of communication ports 211 communicating with the oil drainage grooves 21 are formed in the first spoke 2 and the second spoke 3, and the communication ports 211 are alternately arranged at staggered positions along both sides of the oil drainage grooves 21, extending the travel path of the flue gas, increasing the contact time, and improving the oil particle separation degree.

[0036] Embodiment 3: Referring to Figure 5 and Figure 6As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that a number of oil-blocking strips 7 and straight strips 8 perpendicular to the oil-blocking strips 7 are provided on the side end faces of the first spoke 2 and the second spoke 3; specifically, the oil-blocking strips 7 enhance the oil-catching effect and increase the oil fume collision area. When the oil fume air moves axially along the oil-throwing motor under the suction force generated by the negative pressure of the fan, it collides with the radial oil-catching bars; when the oil fume air moves centrifugally along the spokes of the oil-throwing disc under the centrifugal force generated by the rotation of the oil-throwing disc, it collides with the axially arranged oil-blocking strips 7. The oil-blocking strips 7 and the straight strips 8 can be used alone or in combination to improve the efficiency of capturing oil fume. At the same time, the comb-like structure on the side of the spokes of the oil-throwing disc can act as a vortex generator to "filter" the large air vortices flowing through the surface into fine small vortices, suppressing the generation of turbulent boundary layer noise; when the air flow passes through the trailing edge, vortex shedding separation will occur, and the spokes can make the separation process discrete, suppressing the aerodynamic noise caused by vortex detachment.

[0037] Embodiment 4: Referring to Figure 4 As shown, on the basis of the above-mentioned Embodiment 1, 2 and 3, an extension edge strip 6 is provided on one side end face of the first spoke 2 and the second spoke 3.

[0038] Embodiment 5: Referring to Figure 7 and Figure 8 As shown, the difference from Embodiment 1 is that oil-blocking strips 7 are provided in the first spoke 2, the second spoke 3 and the oil leakage notch 11, and the oil-blocking strips 7 are all arranged on one side and in the same direction.

[0039] In summary, by providing the strips and the communication ports 211, the oil-throwing disc has a better air and oil fume passing effect, reduces the wind resistance, is not easy to accumulate oil and block, has a large collision area in contact with the flue gas, high oil-catching efficiency and high oil removal rate.

[0040] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
