For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1 and Figure 2 As shown, the oil guide structure provided by the utility model comprises a fixed outer shell 1 and a movable inner shell 2 which are slidably connected. The fixed outer shell 1 is fixedly connected to the wall, and the movable inner shell 2 is lifted and lowered from the bottom opening of the fixed outer shell. The movable inner shell 2 is provided with a smoke inlet, and the oil smoke enters the movable inner shell 2 through the smoke inlet and then enters the fixed outer shell 1. The movable inner shell 2 can be lifted and lowered relative to the fixed outer shell 1, so that the vertical position of the smoke inlet can be adjusted to adapt to different cooking scenes.

[0035] An oil cup 4 is provided at the bottom of the movable inner shell 2 , and the oil stains in the movable inner shell 2 can directly fall into the oil cup 4 .

[0036] The fixed housing 1 is provided with an oil collecting cavity for collecting the oil generated on the side wall of the fixed housing 1. The inner wall of the fixed housing 1 receives the oil flowing down from various positions through a groove structure on the circumference, and then finally gathers in the oil collecting cavity.

[0037] like Figure 2 and Figure 3As shown, the oil guide structure also includes an oil guide nozzle 3, which is roughly a columnar structure. The oil guide nozzle 3 is connected between the fixed outer shell 1 and the movable inner shell 2. The oil guide nozzle 3 includes a drainage end 31 and an oil drop end 32 that are relatively arranged, and the oil drop end 32 is lower than the drainage end 31. The inclination angle b of the oil guide nozzle 3 relative to the horizontal plane is greater than 6°. The drainage end 31 is connected to the oil gathering chamber. The oil in the oil gathering chamber flows from the drainage end 31 to the oil drop end 32 under the action of gravity, and the downward projection of the oil drop end 32 falls into the oil cup 4.

[0038] The oil stains generated on the side wall of the fixed outer shell 1 flow downward and gather in the oil collecting chamber, and then drip into the oil cup 4 in a direction through the oil guide nozzle 3 connected to the oil collecting chamber. When the movable inner shell 2 moves up and down, the horizontal position of the oil cup 4 remains unchanged. Therefore, the oil guide nozzle 3 can accurately complete the transfer of the oil stains and prevent the oil stains on the fixed outer shell 1 from dripping onto the stove.

[0039] In this embodiment, there are two oil guide nozzles 3, which are respectively located on the left and right side walls of the fixed housing 1, so that the problem of oil stains dripping on the left and right sides of the fixed housing 1 can be solved.

[0040] An escape recess 21 which is sunken from outside to inside is arranged on the outer wall of the movable inner shell 2 . The escape recess 21 extends vertically, and the oil guide nozzle 3 is located in the escape recess 21 .

[0041] like Figure 3 As shown, in this embodiment, the purpose of avoiding the oil guide nozzle 3 can be achieved by setting the avoidance recess 21 on the left and right side walls of the movable inner shell 2. At the same time, in the top view direction, part of the opening of the oil cup 4 is also exposed, and from top to bottom, the oil can drip into the oil cup 4 along the avoidance recess. The movable inner shell 2 and the oil cup 4 can be completely hidden in the fixed outer shell 1, and the shape and area of ​​the top surface opening of the oil cup 4 can be roughly equal to the shape and area of ​​the bottom surface of the movable inner shell 2, so that the interior of the movable inner shell 2 has a wider smoke guide channel, that is, in the left and right direction, the length of the movable inner shell 2 is roughly equal to the length of the fixed outer shell 1, and only the recess for avoiding the oil guide nozzle 3 is set at a part of the side wall of the movable inner shell 2 to prevent the oil guide nozzle 3 from interfering with the up and down movement of the movable inner shell 2.

[0042] In other feasible schemes, the top opening area of ​​the oil cup 4 may be set larger than the bottom area of ​​the movable inner shell 2, that is, in the left-right direction, the length of the oil cup 4 along the left-right direction is larger than the length of the movable inner shell 2 along the left-right direction. In this way, when viewed from top to bottom, a portion of the opening of the oil cup 4 is not blocked by the movable inner shell 2, and the unblocked portion of the opening of the oil cup 4 is aligned vertically with the oil drop end 32 of the oil guide nozzle 3.

[0043] like Figure 4 and Figure 5As shown, the inner wall of the oil cup 4 is connected with an inner hanging foot, and the inner hanging foot has a first end and a second end which are arranged opposite to each other, the first end of the inner hanging foot is connected to the inner wall of the oil cup 4, and the second end of the inner hanging foot is located inside the oil cup 4 and is used to connect with the movable inner shell 2; the inner hanging foot is located directly below the oil drop end 32; an oil leakage hole 5 is arranged on the inner hanging foot to guide oil pollution into the oil cup 4.

[0044] In this embodiment, the oil cup 4 is connected to the movable inner shell 2 by means of an inner hanging foot, and the inner hanging foot is hidden inside the oil cup 4, which is more beautiful after being connected to the movable inner shell 2. The inner hanging foot can be located directly below the oil drop end 32, receiving the oil dripping from the oil drop end 32, and then draining it into the oil cup 4 from the oil leakage hole 5.

[0045] In other feasible solutions, the oil cup 4 is also connected by means of an inner hanging foot, but the position of the inner hanging foot is not directly below the oil guide nozzle 3, and the oil dripping from the oil guide nozzle 3 can fall directly into the oil cup 4.

[0046] In another feasible scheme, the oil cup 4 can also be connected by means of an external hanging foot, that is, one end of the external hanging foot is connected to the outer wall of the oil cup 4, and the other end is located outside the oil cup 4, and the opening part of the oil cup 4 corresponds to the bottom of the avoidance recess 21.

[0047] The inner hanging foot includes a first plate portion 41, a second plate portion 42 and a third plate portion 43 which are connected in sequence from the first end toward the second end. One end of the first plate portion 41 is connected to the inner wall of the oil cup 4, the other end of the first plate portion 41 is connected to one end of the second plate portion 42, and the second plate portion 42 is bent at an angle relative to the first plate portion 41, the other end of the second plate portion 42 is connected to the third plate portion 43, and the second plate portion 42 and the third plate portion 43 are bent at an angle; the third plate portion 43 is connected to the movable inner shell 2.

[0048] like Figure 4 and Figure 5 As shown, in this embodiment, the first plate portion 41 and the third plate portion 43 are both arranged roughly in the horizontal direction, while the second plate portion 42 is arranged roughly in the vertical direction. The first plate portion 41, the second plate portion 42 and the third plate portion 43 are connected in a "Z" shape. The horizontally arranged first plate portion 41 is opposite to the oil drop end 32 to receive the oil stains, and the second plate portion 42 serves to lift the third plate portion 43, thereby facilitating the connection of the third plate portion 43 with the movable inner shell 2.

[0049] From the first end toward the second end, the first plate portion 41 is inclined downward, and the oil leakage hole 5 is provided at the lowest point of the first plate portion 41 .

[0050] The oil dripping onto the first plate portion 41 may directly slide into the oil cup 4, or may slide onto the oil leakage hole 5 as in the present embodiment, and then flow into the oil cup 4 from the oil leakage hole 5. The angle a between the first plate portion 41 and the horizontal plane is greater than 6°.

[0051] In order to prevent the oil stains on the first plate portion 41 from overflowing from the oil cup 4, the highest point of the first plate portion 41 is lower than the opening edge of the oil cup 4, and the height difference between the two is greater than 5 mm. Even if the oil stains on the first plate portion 41 solidify, they will not easily overflow the edge of the oil cup 4.

[0052] The lifting hood provided by the utility model includes the above-mentioned oil guide structure. Because the lifting hood provided by the utility model adopts the above-mentioned oil guide structure, the lifting hood provided by the utility model also has the advantages of the oil guide structure.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
