Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a flow guide structure of a range hood and the range hood. Background Art

[0002] When the existing wall-mounted range hood starts the cleaning function or is in normal use, oil droplets and washing liquid will pass through the oil ring and flow down the liquid outlet at the rear end of the oil ring. When the amount of oil and / or washing liquid is too much, the oil and / or washing liquid will rush onto the outer shell, and then eject out of the range hood, causing the range hood to leak oil. When the amount of oil and / or washing liquid is too little, the oil and / or washing liquid will flow back along the lower side of the oil ring, drip onto the smoke guide plate set in the smoke hood, and then eject out of the range hood, causing the range hood to leak oil.

[0036] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation methods of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0037] Please refer to Figure 1-Figure 10 The utility model provides a flow guide structure of a range hood, comprising a mounting portion 11 and a flow guide portion 12. The mounting portion 11 is mounted on the inner side wall of the smoke hood 2 of the range hood. The flow guide portion 12 is mounted on the mounting portion 11 and is located at the lower side of the liquid outlet 30 of the oil ring 3 of the range hood. The flow guide portion 12 is tilted downward from front to back to receive the oil stains and / or washing liquid flowing out of the liquid outlet 30 of the oil ring 3, so that the oil stains and / or washing liquid in the oil ring 3 can flow to the inner side wall of the smoke hood 2 through the flow guide portion 12, and then flow along the inner side wall of the smoke hood 2 to the bottom of the smoke hood 2, and then flow through the oil holes opened at the bottom of the smoke hood 2 to the oil cup mounted on the lower side of the smoke hood 2. The problem in the prior art that when the oil stains and / or washing liquid in the oil ring 3 flow out from the liquid outlet 30, the oil stains and / or washing liquid hit the inner wall of the smoke hood 2 due to the large amount of the oil stains and / or washing liquid, and then splash out of the smoke hood 2 from the smoke hood 2; or the problem that the oil stains and / or washing liquid reflux along the bottom side of the oil ring 3 due to the small amount of the oil stains and / or washing liquid, and then drip onto the smoke guide plate 22 arranged under the oil ring 3, and splash out of the smoke hood 2 from the smoke guide plate 22.

[0038] Specifically, when the amount of oil stains and / or washing liquid is large, the oil stains and / or washing liquid move along the Fig. 9 The direction indicated by the middle arrow G splashes onto the guide portion 12; when the amount of oil and / or washing liquid is small, the oil and / or washing liquid flows along Fig. 9 The water drips onto the guide portion 12 in the direction indicated by the middle arrow H.

[0039] Optionally, a baffle 13 is further included, and a baffle 13 is provided on the left and right sides of the guide part 12 to prevent oil stains and / or washing liquid dripping onto the oil guide part from splashing out from the left and / or right sides of the oil guide part, thereby achieving an oil blocking effect.

[0040] Optionally, a liquid guide gap 10 is provided between the baffle 13 and the lower end of the guide portion 12 so that the oil stains and / or washing liquid on the guide portion 12 can flow out to the inner wall of the smoke hood 2 through the liquid guide gap 10 on the left and / or right side of the guide portion 12.

[0041] Optionally, the mounting portion 11, the guide portion 12 and the barrier portion 13 are integrally formed, which can ensure the strength of the guide structure 1 on the one hand, and prevent oil and / or washing liquid from overflowing through the gap between the guide portion 12 and the barrier portion 13, or through the gap between the mounting portion 11 and the guide portion 12 on the other hand.

[0042] On the other hand, the utility model provides a range hood, comprising a fume hood 2, a bellows assembly 5 arranged on the upper side of the fume hood 2, an oil ring 3 arranged between the fume hood 2 and the bellows assembly 5, and the above-mentioned guide structure 1 of the range hood.

[0043] Optionally, an oil receiving groove 31 is provided on the oil ring 3, and the oil receiving groove 31 is used to receive oil and / or washing liquid in the bellows assembly 5. The oil receiving groove 31 is inclined downward from front to back, and the liquid outlet 30 is provided at both ends of the rear side of the oil receiving groove 31. The smoke hood 2 includes a smoke hood body 21, and a smoke collecting chamber 200 with a smoke inlet 20 on the front side is formed in the smoke hood body 21. The mounting portion 11 is mounted on the inner wall of the rear side plate 211 of the smoke hood body 21.

[0044] Optionally, a raised liquid guiding portion 2111 raised toward the center of the smoke collecting chamber 200 is further provided on the inner wall of the rear side panel 211. The raised liquid guiding portion 2111 is arranged below the guide structure 1 and is inclined from bottom to top so that the oil and / or washing liquid flowing out of the liquid guiding notch 10 can gradually flow along the raised liquid guiding portion 2111 to the bottom of the smoke collecting hood 2.

[0045] Optionally, at least two raised liquid-guiding portions 2111 are provided, and the two raised liquid-guiding portions 2111 are arranged at intervals to ensure a flow-guiding effect.

[0046] Specifically, the oil stains and / or washing liquid in the oil ring 3 are moved along Figure 4 The air flows in the direction indicated by the arrow E to the bottom of the smoke hood.

[0047] Optionally, the smoke hood 2 also includes a smoke guide plate 22 arranged in the smoke collecting chamber 200. The smoke guide plate 22 is inclined upward from front to back and forms an oil passage 100 between the smoke guide plate 22 and the rear side plate 211. The oil and / or washing liquid flowing out of the liquid guide gap 10 flows along the raised liquid guide portion 2111 in the oil passage 100 to the bottom end of the smoke hood 2. The smoke guide plate 22 can better block the oil and / or washing liquid in the oil passage 100, which plays an aesthetic role and can also prevent some oil and / or washing liquid from splashing out of the smoke hood 2 when dripping.

[0048] Optionally, the smoke guide plate 22 includes a smoke guide plate body 221 and a flow guide end 222 disposed at the upper end of the smoke guide plate 22, the smoke guide plate body 221 is disposed upwardly inclined from front to back, and the flow guide end 222 is disposed downwardly inclined from front to back and is located below the oil ring 3, when oil stains and / or washing liquid are accumulated on the lower side of the oil ring 3, the oil stains and / or washing liquid on the lower side of the oil ring 3 can drip onto the flow guide end 222, and then flow into the oil passage 100 along the flow guide end 222. Even if the oil stains and / or washing liquid on the lower side of the oil ring 3 drip onto the flow guide end 222 and splash, the splashed oil stains and / or washing liquid will only splash onto the rear side plate 211, thereby preventing the oil stains and / or washing liquid from splashing out of the smoke collecting hood 2.

[0049] Optionally, a flap assembly 4 is further included, the upper end of which is mounted on the upper side of the smoke collecting hood 2 and can swing relative to the smoke collecting hood 2 to close and open the smoke inlet 20 .

[0050] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all belong to the protection scope of the present invention.
