Description

Technical Field

[0001] The utility model relates to the technical field of range hood appliances, and more specifically, to an oil slinger for a range hood. Background Art

[0002] A range hood is an essential electrical appliance used to extract cooking fumes in kitchens or canteens. 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 rate 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 cooking fumes, the higher the oil fume separation rate.

[0003] The dynamic shield of a range hood mainly consists of an oil slinger, a motor, and a housing. When the oil slinger rotates, it collides with the cooking fume air, captures the cooking fume molecules, and then throws them out by centrifugal force to complete the capture and collection of kitchen cooking fumes and purify the environmental air. This application aims to solve the problem of relatively low oil fume separation rate and oil removal rate of some existing range hoods by improving the oil slinger. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an oil slinger for a range hood that can improve the oil fume separation rate and oil removal rate.

[0005] The embodiment of the utility model is realized by the following technical solutions: An oil slinger for a range hood includes a central disk and a plurality of blades evenly arranged around the central disk. The central disk is used to be connected to the motor of the range hood; The blades are provided with at least two layers along the axial direction of the central disk, and the blades are provided with smoke guiding ridges to form a bending structure.

[0006] Furthermore, adjacent layers of the blades are arranged with a circumferential offset, and the smoke guiding ridges of adjacent layers of the blades are arranged in opposite directions.

[0007] Furthermore, the central disk includes a positioning disk and an installation disk stacked in sequence. One end of the blade is provided with a positioning opening adapted to and fitting with the edge of the positioning disk, and one end of the blade is connected to the installation disk.

[0008] Furthermore, the size of the blade gradually increases radially outward along the central disk.

[0009] Furthermore, a mounting hole for connecting to the motor is provided in the middle of the central disk.

[0010] Furthermore, the cross-section of the blade is a V-shaped structure.

[0011] Furthermore, the bending angle of the blade is 45° - 60°.

[0012] The technical solution of the embodiment of the present utility model has at least the following advantages and beneficial effects: By setting a double-layer bent blade structure with the two layers of blades staggered, the contact area between the oil throwing disc and the oil fume is increased, which helps the oil droplets to gather. When the oil throwing disc rotates, the oil droplets are more easily centrifuged out, improving the oil fume separation degree and the oil removal rate. Brief Description of the Drawings

[0018] To make the purpose, technical solution and advantages of the embodiment of the present utility model clearer, the technical solution in the embodiment of the present utility model will be clearly and completely described below with reference to the drawings in the embodiment of the present utility model. Obviously, the described embodiment is part of the embodiments of the present utility model, rather than all of them. Usually, the components of the embodiment of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the 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.

[0020] 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.

[0021] The following is further described in conjunction with specific embodiments. Figures 1 - 3 As shown, the present embodiment is an oil-spinning plate of a range hood, comprising a central plate 1 and a plurality of blades 2 uniformly arranged around the central plate 1, the central plate 1 being used to be connected to the motor of the smoke hood; the blades 2 are provided with at least two layers along the axial direction of the central plate 1, and the blades 2 are provided with smoke guide ridges 21 to form a bent structure; specifically, the oil-spinning plate is installed on the motor of the range hood to drive, and when the range hood is working, when the oil mist floats up and passes through the oil-spinning plate, it is diverted along the smoke guide ridges 21 and enters between the two layers of blades 2, and the blades 2 with a bent structure increase the contact area of the oil mist, and the oil particles contact and adhere to the surface of the blades 2 to form accumulation, and under the action of centrifugal force, the oil particles are radially thrown out of the oil-spinning plate along the blades 2; and when the oil-spinning plate stops working, under the action of gravity, the oil particles drip into the bent grooves of the blades 2 along the inclined surface and accumulate, and when the oil-spinning plate is started next time, the oil droplets are larger and easier to be centrifugally thrown out, which has a higher oil removal rate and also improves the oil smoke separation degree.

[0022] Reference Figure 1 As shown, the two adjacent layers of blades 2 in this embodiment are circumferentially staggered, and the smoke guide ridges 21 of the two adjacent layers of blades 2 are arranged in opposite directions; specifically, the smoke guide ridge 21 is arranged at one end facing the oil smoke, and the two side edges of the blades 2 are respectively aligned with the bending grooves of the other layer of blades 2, so that the oil can accumulate and drip into them and be thrown out, avoiding excessive accumulation of oil on the oil-slinging plate, increasing the overall weight of the oil-slinging plate, forming a rotation obstacle, and reducing the efficiency of intercepting oil particles.

[0023] Reference Figure 2 As shown, the center disk 1 in this embodiment includes a positioning disk 12 and a mounting disk 11 stacked in sequence, one end of the blade 2 is provided with a positioning opening 22 that fits with the edge of the positioning disk 12, and one end of the blade 2 is connected to the mounting disk 11; specifically, in order to ensure that the installation angle and the extended length of each blade 2 are consistent, a right-angle positioning opening 22 is provided at one end of the blade 2 and is placed evenly spaced close to the positioning disk 12, and the mounting disk 11 and the blade 2 form an integrated structure.

[0024] Reference Figure 3 As shown, the size of the blades 2 is gradually increased radially outward from the center disk 1, and the two layers of blades 2 are inclined in opposite directions, which is beneficial to the ejection of oil droplets.

[0025] In order to facilitate the installation of the oil-slinging pan, a mounting hole 13 for connecting with the motor is provided in the middle of the center pan 1, and the motor shaft passes through the mounting hole 13 and is fixed with a nut.

[0026] In addition, the cross section of the blade 2 is a V-shaped structure, and the inclined plates on one side of the two blades 2 on the upper layer correspond to the V-shaped grooves of the lower blades 2 respectively, so that the oil droplets can be easily dripped into and collected after gathering.

[0027] Preferably, the bending angle of the blade 2 can be set to 45°-60°.

[0028] 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, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
