[0028] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0029] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0031] The embodiment of the utility model provides a top suction and side suction hybrid range hood capable of guiding oil, such as Figure 1-3 As shown, it includes a main box 100, a smoke hood and an oil cup 400. The smoke hood includes a top suction part 200 and a side suction part 300. The main box 100 is fixed on the top of the top suction part 200, and the oil cup 400 is fixed on the bottom of the side suction part 300. A fan is arranged in the main box 100. The top suction part 200 and the side suction part 300 both have inner cavities that are connected to each other. The inner cavities are used for smoke flow. The internal space of the main box 100 is connected with the inner cavity of the top suction part 200. The top suction part 200 includes a bottom plate 210 located at the bottom thereof. The bottom plate 210 is provided with a plurality of smoke inlet holes 201. The front side of the side suction part 300 is provided with a smoke inlet 301. When the fan in the main box 100 is working, the oil smoke can enter the smoke hood through the smoke inlet holes 201 and the smoke inlet 301 respectively, and then flow to the main box 100, and then be discharged through the corresponding smoke exhaust channel, thereby achieving the extraction of oil smoke.

[0032] The bottom plate 210 is arranged obliquely relative to the horizontal direction, and the height of the bottom plate 210 gradually increases in the direction extending forward, so the rear side of the bottom plate 210 has a small height and the front side has a large height. An oil collecting tank 220 extending in the left-right direction is arranged at the rear side of the bottom plate 210, and an oil leakage hole 221 is arranged at at least one end of the oil collecting tank 220 in the left-right direction, that is, the oil leakage hole 221 is arranged at the left end of the oil collecting tank 220, or the oil leakage hole 221 is arranged at the right end of the oil collecting tank 220, or the oil leakage hole 221 is arranged at both the left end and the right end of the oil collecting tank 220, and the oil in the oil collecting tank 220 can flow out through the oil leakage hole 221. An oil guide structure 500 is provided in the side suction part 300. The oil guide structure 500 is located at the side portion corresponding to the oil leakage hole 221 in the left-right direction of the side suction part 300. When the oil leakage hole 221 is provided at the right end of the oil collecting tank 220, the oil guide structure 500 is provided on the right side of the side suction part 300. When the oil leakage hole 221 is provided at the left end of the oil collecting tank 220, the oil guide structure 500 is provided on the left side of the side suction part 300. When the oil leakage hole 221 is provided at both the left and right ends of the oil collecting tank 220, the oil guide structure 500 is provided on both the left and right sides of the side suction part 300. The oil guide structure 500 is docked with the oil leakage hole 221 to receive the oil flowing out of the oil leakage hole 221, and the oil guide structure 500 is used to guide the oil to flow toward the rear side wall of the side suction part 300. A through hole 302 is provided at the bottom of the side suction part 300 . The through hole 302 is located above the oil cup 400 . The oil flowing into the bottom of the side suction part 300 can flow to the oil cup 400 through the through hole 302 .

[0033] In this embodiment, the oil attached to the bottom plate 210 will automatically move to the rear side of the bottom plate 210 under the action of gravity, and then flow into the oil collecting tank 220. The oil in the oil collecting tank 220 will then flow out from the oil leakage hole 221, and will be guided to the rear side wall of the side suction part 300 through the oil guide structure 500. The oil will flow downward along the rear side wall of the side suction part 300, and finally flow into the oil cup 400 through the perforation 302 at the bottom of the side suction part 300. The oil cup 400 collects the oil. This structure mainly guides the oil to the rear side wall of the side suction part 300, and the oil is not easy to flow to the front side of the side suction part 300. Therefore, the oil is not easy to flow to the surface of the smoke hood, and it is not easy to form oil marks on the surface of the smoke hood, which improves the user experience. At the same time, since the oil guide structure 500 is located on the side of the side suction part 300 in the left and right directions, it has little effect on the airflow sucked from the smoke inlet 301, which is convenient for the smooth flow of oil smoke to ensure the oil smoke absorption effect.

[0034] In some embodiments, Figure 2 , Figure 4 and Figure 5As shown, the oil guide structure 500 includes an oil guide side plate 510 arranged in the vertical direction and an oil guide member 520 fixed on the oil guide side plate 510. The oil guide member 520 is located below the oil leakage hole 221 to receive the oil dripping from the oil leakage hole 221, and the oil guide member 520 is used to guide the oil to flow toward the rear side wall of the side suction part 300. The oil guide side plate 510 is used to support and fix the oil guide member 520, and can also be used to guide part of the oil. Part of the oil can flow downward along the oil guide side plate 510 and then flow into the oil cup 400.

[0035] Further, the oil guide member 520 includes a mounting plate 521 and an oil guide plate 522 connected to the mounting plate 521, and the mounting plate 521 is fixed on the oil guide side plate 510 to install and fix the oil guide plate 522. The oil guide plate 522 is tilted relative to the horizontal direction, and the height of the oil guide plate 522 gradually decreases in the direction of extending backward, so that the oil can move toward the rear end along the oil guide plate 522. The rear end of the oil guide plate 522 abuts against the rear side wall of the side suction part 300, and the oil can flow directly to the rear side wall of the side suction part 300 along the oil guide plate 522, or the rear end of the oil guide plate 522 is spaced from the rear side wall of the side suction part 300 by a preset distance, and the preset distance is determined by those skilled in the art according to actual conditions. Due to the existence of the preset distance, a gap is formed between the oil guide plate 522 and the rear side wall of the side suction part 300, and the oil can flow downward through the gap.

[0036] The mounting plate 521 and the oil guide plate 522 may be integrally connected, and the two may be formed by bending a plate. The mounting plate 521 may be closely fixed on the oil guide side plate 510 to prevent the oil from flowing directly downward along the oil guide side plate 510, so that more oil can move toward the rear end along the oil guide plate 522. The mounting plate 521 may be fixed on the oil guide side plate 510 by screws, welding, or pasting.

[0037] Furthermore, in the direction perpendicular to the oil guide side plate 510 and away from the oil guide side plate 510, the height of the oil guide plate 522 gradually increases, and the height of the side of the oil guide plate 522 away from the oil guide side plate 510 is greater, so that the oil is not easy to move to the side of the oil guide plate 522 away from the oil guide side plate 510, and the oil mainly moves along the oil guide plate 522 to its rear end to improve the oil guiding effect.

[0038] In some embodiments, the front side of the oil guide side plate 510 is connected to the front guide plate 530, and the front guide plate 530 can be used to install the smoke baffle 310. The rear side of the front guide plate 530 is provided with a protruding boss 540, and the boss 540 is provided with a penetrating mounting hole 541. Since the boss 540 protrudes from the rear side of the front guide plate 530, it has a certain blocking effect on the oil. The oil flowing along the front guide plate 530 is not easy to pass through the mounting hole 541 on the boss 540, so as to reduce the risk of oil leakage from the mounting hole 541, and further make it difficult for the oil to flow to the outer surface of the smoke hood.

[0039] In some embodiments, Figure 1-3 As shown, the side suction part 300 includes a smoke baffle 310 located on the front side thereof, and the smoke inlet 301 is arranged below the smoke baffle 310. The rear end of the bottom plate 210 extends to the rear side of the smoke baffle 310, so that the oil is not easy to flow to the front side of the smoke baffle 310. At the same time, the bottom plate 210 and the smoke baffle 310 are spaced apart by a preset distance, and the two are not in contact. The oil on the bottom surface of the bottom plate 210 basically does not flow to the smoke baffle 310, further making it difficult for the oil to flow to the outer surface of the smoke hood.

[0040] The preset distance may be 5 mm.

[0041] The side suction portion 300 may further include a rear side panel located at its rear side, a left side panel located at its left side, a rear side panel located at its rear side and a bottom panel located at its bottom. The smoke shield 310, the rear side panel, the bottom panel, the left side panel and the right side panel together form an inner cavity of the side suction portion 300. The inner side wall of the rear side panel may form the rear side wall of the side suction portion 300 of the above embodiment.

[0042] In some embodiments, Figure 2 , Figure 3 and Figure 6 As shown, a rear baffle plate 230 protruding upward is provided on the rear side of the bottom plate 210, and an oil collecting groove 220 is formed between the rear baffle plate 230 and the bottom plate 210. The rear baffle plate 230 can prevent the oil from continuing to flow backward along the bottom plate 210, so that the oil is collected in the oil collecting groove 220, and the oil in the oil collecting groove 220 can move to the left and right ends thereof, and then flow out through the oil leakage hole 221.

[0043] In some embodiments, Figure 3 and Figure 6As shown, the bottom plate 210 forms a first preset angle a with the horizontal direction; the bottom plate 210 also includes an oil mesh plate 240, and the smoke inlet 201 is arranged on the oil mesh plate 240; the oil mesh plate 240 is arranged obliquely, and the height of the oil mesh plate 240 gradually increases in the direction of forward extension, and the oil mesh plate 240 forms a second preset angle b with the horizontal direction, and the second preset angle b is greater than the first preset angle a. The oil on the oil mesh plate 240 can move backward along the oil mesh plate 240 under the action of gravity, and the oil on the front side of the oil mesh plate 240 can move backward along the bottom plate 210. Since the second preset angle b is greater than the first preset angle a, the oil mesh plate 240 is equivalent to tilting upward, which can increase the bottom area of ​​the bottom plate 210 to improve the smoke collection effect, so that more oil smoke can pass through the smoke inlet 201.

[0044] Furthermore, the first preset angle a can be set to be greater than or equal to 7°, and the second preset angle b can be set to be greater than or equal to 12°.

[0045] In some embodiments, the side suction part 300 includes an oil collecting plate 320 at the bottom thereof, the oil collecting plate 320 is fixedly connected to the rear side wall of the side suction part 300, and the through hole 302 is provided on the oil collecting plate 320. The oil flowing downward along the rear side wall of the side suction part 300 will flow onto the oil collecting plate 320, and then flow into the oil cup 400 from the through hole 302 on the oil collecting plate 320.

[0046] The oil collecting plate 320 can be tilted relative to the horizontal direction to improve its oil guiding effect, and at the same time, it also guides the airflow sucked from the smoke inlet 301. The oil collecting plate 320, the two oil guiding side plates 510, the smoke baffle plate 310 and the rear side plate can enclose a cavity of the side suction part 300.

[0047] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
