Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an oil guide structure for a range hood and a range hood. Background Art

[0002] The range hood is an important appliance for extracting and exhausting oil smoke in the kitchen. The range hood generally includes a housing, which has a smoke collecting chamber and a smoke inlet connected to the smoke collecting chamber. A fan for negative pressure oil smoke extraction is installed in the smoke collecting chamber, and an oil net for filtering grease in the oil smoke and a smoke baffle for controlling the opening or closing of the smoke inlet are installed in the smoke collecting chamber. A driving mechanism for driving the smoke baffle to open and close is also installed in the smoke collecting chamber.

[0003] However, during the use of the range hood, some grease will still follow the fumes into the smoke collecting chamber through the mesh of the oil net. The grease that enters the smoke collecting chamber cannot be discharged smoothly and is easily adsorbed on the inner wall of the smoke collecting chamber. Over time, in winter, the grease is easy to condense and form grease, which is easy to breed bacteria and emit odor, endangering human health. In summer, the grease is easy to accumulate into droplets. After the grease on the top wall of the smoke collecting chamber accumulates into droplets, it will directly drip from the mesh of the oil net onto the stove or cooking pot, seriously affecting the user experience. For this reason, the prior art usually installs an oil guide structure in the smoke collecting chamber to facilitate the flow of grease. However, since a drive mechanism is also installed in the smoke collecting chamber, the grease that enters the smoke collecting chamber may also directly adhere to the drive mechanism. Over time, it is easy to corrode the drive mechanism, causing damage to the drive mechanism and affecting the normal use of the drive mechanism. Utility Model Content

[0059] It is understandable that the upper end of the second oil guide surface 310 extends to the vicinity of the front side wall 112, which is only for Figures 2 to 7In order to prevent the oil smoke from flowing upward to the top wall 111 of the smoke collecting chamber 110, in some embodiments, the upper end of the second oil guiding surface 310 may be directly extended to abut against the front side wall 112 of the smoke collecting chamber 110, and the present invention does not make any specific limitation on this.

[0060] It can be understood that the second oil guide plate 300 is installed on the smoke collecting chamber 110. Specifically, the second mounting plate 230 can be installed on the inner wall of the smoke collecting chamber 110 by fasteners such as screws or bolts, or the second mounting plate 230 can also be installed on the inner wall of the smoke collecting chamber 110 by a snap-on structure or other connecting structures. The present invention does not make specific limitations on this.

[0061] Reference Figures 2 to 7 In some embodiments, the second oil guide surface 310 includes a first surface 311 and a second surface 312, the first surface 311 is adjacent to or abuts against the front side wall 112 and extends backward along a top-to-bottom direction, and the second surface 312 is connected to the lower end of the first surface 311 and extends backward along a top-to-bottom direction; in the vertical direction, the projection of the lower end of the second surface 312 is located on the rear side of the projection of the oil net 120.

[0062] In the above structure, by dividing the second oil guide surface 310 into a first surface 311 and a second surface 312, and in the vertical direction, the projection of the lower end of the second surface 312 is located on the rear side of the projection of the oil net 120, it is convenient to guide the grease to flow and drip to the bottom of the smoke collecting chamber 110, reduce the grease dripping to the front side wall 112 of the smoke collecting chamber 110 and flow along the front side wall 112 to the bottom of the smoke collecting chamber 110, thereby speeding up the guidance of the grease to drip to the bottom of the smoke collecting chamber 110.

[0063] It can be understood that the second oil guide surface 310 includes a first surface 311 and a second surface 312. Figures 2 to 7 In some embodiments, the second oil guide plate 300 includes a first plate and a second plate. The second plate is formed by bending the lower edge of the first plate backward.

In addition, the third oil guide surface 410 can also guide the oil smoke to flow to the air inlet of the fan 130.

[0071] Reference Figures 2 to 11 In some embodiments, the front side wall 112 of the smoke collecting chamber 110 is provided with a fourth oil guide plate 500 located above the oil net 120, and the side surface of the fourth oil guide plate 500 facing away from the front side plate has a fourth oil guide surface 510 extending backward from top to bottom; an oil guide groove 520 is provided below the fourth oil guide surface 510, and the oil guide groove 520 is located above the oil net 120 and arranged along the length direction of the oil net 120, and the two ends of the oil guide groove 520 extend correspondingly to be flush with the two ends of the oil net 120, or the two ends of the oil guide groove 520 extend correspondingly to the outside of the oil net 120.

[0072] In the above structure, by setting the fourth oil guide plate 500, the grease on the front side wall 112 of the smoke collecting chamber 110 can flow downward along the front side wall 112 to the fourth oil guide plate 500, and flow downward along the fourth oil guide surface 510, and finally drip into the oil guide groove 520. The grease in the oil guide groove 520 can diffuse and flow to both sides. The grease flowing to the two ends of the oil guide groove 520 can flow downward along the inner side wall of the smoke collecting chamber 110 to the bottom of the smoke collecting chamber 110, and will not flow to the oil net 120 and drip from the mesh of the oil net 120 into the stove or cooking pots, thereby making the kitchen environment more hygienic.

[0073] It is understandable that the housing 100 is installed with a glass panel 150 located above the oil net 120, the inner surface of the glass panel 150 is the front side wall 112 of the smoke collecting chamber 110, and the fourth oil guide plate 500 is installed on the glass panel 150. Specifically, the fourth oil guide plate 500 can be installed on the glass panel 150 by bonding.

[0074] Reference Figures 2 to 11 In some embodiments, the cross-sectional shape of the oil guiding groove 520 is “V”-shaped, and in the vertical direction, the lower end of the fourth oil guiding surface 510 is aligned with the lowest point of the oil guiding groove 520 .

[0075] In the above structure, by setting the cross-sectional shape of the oil guide groove 520 to be "V"-shaped, it is easy to guide the flow of grease in the oil guide groove 520, so that the grease can quickly flow to both ends of the oil guide groove 520. By aligning the lower end of the fourth oil guide surface 510 with the lowest point of the oil guide groove 520 in the vertical direction, the grease on the fourth oil guide surface 510 can drip directly to the bottom of the oil guide groove 520, saving the time for the grease to flow down along the side wall of the oil guide groove 520 to the bottom of the oil guide groove 520, thereby facilitating the improvement of the oil guide efficiency.

[0076] Reference Figure 1 An embodiment of the utility model further provides a range hood, which is provided with the range hood oil guide structure of any of the above embodiments.

[0077] In the above structure, by setting the oil guide structure of the range hood of any of the above embodiments, the oil guide structure of the range hood is provided with an oil guide plate assembly, and the oil guide plate assembly includes a first oil guide plate 200. The first oil guide plate 200 can block the oil smoke from flowing upward to the top wall 111 of the smoke collecting chamber 110, so that the grease in the oil smoke can adhere to the first oil guide surface 210 of the first oil guide plate 200 and flow along the first oil guide surface 210 to the lower end of the first oil guide surface 210, and finally drip directly to the bottom of the smoke collecting chamber 110, or drip to the front side wall 112 of the smoke collecting chamber 110 and flow along the front side wall 112 to the bottom of the smoke collecting chamber 110, and will not drip from the mesh of the oil net 120 to the stove or cooking pots, making the kitchen environment more hygienic. In addition, the first oil guide plate 200 is also provided with a first mounting plate 220 extending upward, and the first mounting plate 220 and the first oil guide plate 200 are mutually enclosed to form a mounting groove 240, so that the driving mechanism for driving the smoke guide plate to open and close can be installed in the mounting groove 240, and the first oil guide surface 210 can prevent the oil smoke from flowing upward into the mounting groove 240, so as to protect the driving mechanism and reduce the probability of grease adhering to the driving mechanism and affecting the normal operation of the driving mechanism. As a result, the range hood can guide the grease to flow to the bottom of the smoke collecting chamber 110 while protecting the driving mechanism, thereby increasing the service life of the range hood and greatly improving the user experience.

[0078] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
