[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] In the description and claims of the present application, terms used for indicating directions, such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", etc., are used to describe various example structural parts and elements of the present application, but these terms are used herein only for the purpose of convenience of description and are determined based on the example orientation shown in the drawings. Since the embodiments disclosed in the present application can be arranged in different directions, these terms indicating directions should only be used as description and should not be considered as limitation, such as "upper" and "lower" are not necessarily limited to the direction opposite or consistent with the direction of gravity.

[0034] Figures 1-9An oil cup device for a range hood and a preferred embodiment of the range hood are shown. The range hood comprises a casing and a centrifugal fan (not shown) arranged in the casing, and the casing generally comprises a fan frame 11 and a smoke collecting hood 12 arranged at the bottom of the fan frame 11, and the inner cavity of the fan frame 11 is in communication with the inner cavity of the smoke collecting hood 12. The centrifugal fan is arranged in the fan frame 11, and the centrifugal fan generates negative pressure when operating, and external oil fume can be sucked into the smoke collecting hood 12 through the air inlet of the smoke collecting hood 12. The bottom of the smoke collecting hood 12 is provided with an oil cup device for receiving oil stains flowing down from the smoke collecting hood 12.

[0035] Referring to Figure 5 and Figure 9 , the smoke collecting hood 12 of the embodiment is rotatably connected to the fan frame 11 in a manner of being able to deflect forward and backward relative to the fan frame 11, and the fan frame 11 can be achieved by a connecting rod mechanism, a gear and rack mechanism or a hinge mechanism. Specifically, when the fan frame 11 and the smoke collecting hood 12 adopt the connecting rod mechanism, the deflection of the smoke collecting hood 12 is achieved by the rotation and displacement of the connecting rod, one end of the connecting rod is hinged to the fan frame 11, and the other end is hinged to the smoke collecting hood 12, and when the connecting rod is manually or driven by a motor, the smoke collecting hood 12 will deflect forward and backward relative to the fan frame 11 by a certain angle around the hinge point. When the fan frame 11 and the smoke collecting hood 12 are connected by the gear and rack mechanism, a rack is installed on the fan frame 11 or the smoke collecting hood 12, and the rotation of the gear driven by the motor is meshed with the rack, thereby driving the smoke collecting hood 12 to move forward and backward along the direction of the rack to achieve deflection. The fan frame 11 and the smoke collecting hood 12 can also be connected by a hinge mechanism, and the deflection of the smoke collecting hood 12 is achieved by changing the angle or position of the hinge. For example, when it is necessary to adjust the position of the smoke collecting hood 12, the hinge fixing device is loosened, and after adjusting to the appropriate angle, it is fixed again to make the smoke collecting hood 12 deflect forward and backward relative to the fan frame 11. The structure design that the smoke collecting hood 12 can deflect forward and backward relative to the fan frame 11 can better capture oil fume on the one hand, and the oil fume generated during cooking will spread in all directions, and the smoke collecting hood 12 can deflect forward and backward to adjust according to the diffusion direction of the oil fume, so that the air inlet is closer to the source of the oil fume, effectively increasing the contact area of the air inlet and the oil fume, thereby more accurately capturing the oil fume, improving the absorption rate of the oil fume, and reducing the residual oil fume in the kitchen. On the other hand, it can adapt to different cooking methods, and different cooking methods will produce different oil fume directions. For example, when frying, the oil fume is relatively concentrated and quickly rises, while when stewing, the oil fume is relatively dispersed and rises slowly. The deflectable design of the smoke collecting hood 12 can flexibly adjust the angle according to the characteristics of the oil fume generated by various cooking methods, to ensure that better oil fume absorption effect can be achieved in different cooking scenes. At the same time, the smoke collecting hood 12 deflecting forward and backward relative to the fan frame 11 also improves the user's convenience, avoids head-on and blocks the line of sight, and is convenient for cleaning and maintenance.

[0036] Referring to Figures 1-5The oil cup device of the embodiment is arranged at the bottom of the fume hood 12 and can swing with the fume hood 12. In order to prevent the oil in the oil cup from spilling or overflowing due to the deflection of the fume hood 12, the oil cup device adopts an inner container 30 component that can maintain a constant vertical state. Specifically, the oil cup device includes an outer oil cup 20, an inner container 30, and an oil guide sheet 40.

[0037] The outer oil cup 20 has an open top and is long and extends in the left-right direction and is arranged at the bottom of the fume hood 12. The inner container 30 is also long and extends in the left-right direction. The inner container 30 is located in the outer oil cup 20 and also has an open top. The length of the inner container 30 is slightly smaller than the length of the outer oil cup 20. The left and right ends of the length of the inner container 30 are rotationally connected to the inner walls of the left and right ends of the outer oil cup 20, and the rotation axis extends in the horizontal direction.

[0038] Referring to Figure 2 and Figure 4 , the inner container 30 is detachably connected in the outer oil cup 20. Specifically, the inner walls of the two ends of the length of the outer oil cup 20 each have a second protruding buckle 22 that protrudes outward into the outer oil cup 20. That is, the second protruding buckle 22 at the left end of the outer oil cup 20 protrudes to the right, and the second protruding buckle 22 at the right end protrudes to the left. The ends of the second protruding buckles 22 at the two ends of the outer oil cup 20 each have a second limiting stop 221 that extends to the side. The main body of the second protruding buckle 22 is a cylindrical structure, and the second limiting stop 221 is also a circular stop structure. The two ends of the length of the inner container 30 each have a vertically extending sliding groove 31. The sliding groove 31 is a strip-shaped sliding groove 31 with an inner width and an outer width. Specifically, the bottom of the sliding groove 31 has a mounting opening 311 for the second protruding buckle 22 to slide into, and the side of the sliding groove 31 has a clearance opening 312. The width of the clearance opening 312 is greater than the outer diameter of the main body of the second protruding buckle 22 and less than the outer diameter of the second limiting stop 221. The top edge of the clearance opening 312 is concave in a circular arc shape, so as not to interfere with the rotation of the second protruding buckle 22 relative to the inner container 30. After the sliding groove 31 of the inner container 30 and the second protruding buckle 22 on the outer oil cup 20 are assembled in place, the two second protruding buckles 22 of the outer oil cup 20 can be rotationally constrained in the two sliding grooves 31 of the inner container 30. When the outer oil cup 20 deflects forward and backward with the fume hood 12, the inner container 30 can adjust its posture under the action of its own gravity and maintain a vertical state.

[0039] The second protruding buckle 22 described above can be connected to the inner wall of the outer oil cup 20 by adhesion or welding.

[0040] The two ends of the length direction of the inner container 30 also have a handle part 32 for the user to hold, wherein the handle part 32 is a plate body extending upward from the top opening edge of the inner container 30, and a handle hole 320 is formed in the handle part 32. The operator or user can directly pull the inner container 30 upward through the handle hole 320 to take out the inner container 30 from the outer oil cup 20, and the same is true when placing the inner container 30 into the outer oil cup 20, which is more convenient and fast.

[0041] The outer oil cup 20 of the embodiment is in a T-shaped structure as a whole, including a first cup body 201 extending leftward and rightward, and a second cup body 202 extending rearward from the middle part of the first cup body 201. The inner container 30 is arranged in the first cup body 201, and the second cup body 202 is used to be fixedly installed with the bottom of the smoke collecting hood 12. Among them, the top of the second cup body 202 has two insertion pieces 24 folded inward toward the second cup body 202 on the left and right sides, and the bottom of the smoke collecting hood 12 is correspondingly provided with two insertion grooves 120, and the two insertion pieces 24 of the second cup body 202 are inserted into the two insertion grooves 120 of the smoke collecting hood 12 from front to back.

[0042] The first oil cup is also provided with a decorative plate 23 on the front side wall, which can be a glass plate for the user to conveniently wipe and clean.

[0043] Referring to Figure 2 and Figure 3 , the oil guide piece 40 is detachably connected to the inner wall of the outer oil cup 20, wherein the oil guide piece 40 is also a long strip extending along the left and right directions, the top of the oil guide piece 40 is arranged adjacent to the top opening edge of the outer oil cup 20, and the oil guide piece 40 is inclined downward to the inside of the outer oil cup 20 as a whole. The inner container 30 is located below the oil guide piece 40, and during the rotation of the inner container 30 relative to the outer oil cup 20, the vertical projection of the lower edge of the oil guide piece 40 is always located in the top opening of the inner container 30. Therefore, even if the smoke collecting hood 12 is in a relative inclined state during the operation of the range hood, the oil guide piece 40 can guide the collected oil into the inner container 30, avoiding the oil falling into the outer oil cup 20 or dripping on the outer wall of the inner container 30, which makes the cleaning of the oil cup difficult and affects the user experience.

[0044] The oil guide piece 40 is in an L-shaped structure, including a vertical part 41 used to abut and connect with the inner wall of the outer oil cup 20, and an inclined part 42 extending downward to the inside of the outer oil cup 20 from the bottom of the vertical part 41, and the inner container 30 is located below the inclined part 42 of the oil guide piece 40. The vertical part 41 of the oil guide piece 40 is in a flat plate structure, which can be conveniently connected and fixed with the inner wall of the outer oil cup 20.

[0045] The inner wall of the outer oil cup 20 has a first protruding buckle 21 protruding inwardly into the outer oil cup 20, and the vertical portion 41 of the oil guiding sheet 40 is provided with a connecting hole 410 for connecting with the first protruding buckle. Generally, the connecting hole 410 on the oil guiding sheet 40 can be a conventional circular hole, a waist-shaped hole or an oval hole, etc. In order to further ensure the firmness of the connection between the oil guiding sheet 40 and the outer oil cup 20, the end of the first protruding buckle 21 has a first limiting baffle 211 extending to the side, and the connecting hole 410 is provided as a gourd-shaped hole with the upper part being smaller and the lower part being larger. When installing the oil guiding sheet 40, the first limiting baffle 211 of the first protruding buckle 21 passes through the gourd-shaped hole, and then the oil guiding sheet 40 is released, and the first limiting baffle 211 of the first protruding buckle 21 can form a limit with the upper area of the peripheral edge of the gourd-shaped hole.

[0046] The length of the oil guiding sheet 40 is consistent with the length of the inner container 30, and both ends of the oil guiding sheet 40 in the length direction have oil blocking protruding baffles 43 extending upward. When the amount of oil collected is large, the oil blocking protruding baffles 43 at both ends of the oil guiding sheet 40 can block the oil fume from flowing to the left and right sides, avoiding dripping outside the inner container 30.
