Description

Technical Field

[0002] The integration of kitchen appliances and home furnishings has become an industry consensus. As the most important kitchen appliance, the range hood is becoming increasingly slim. When turned on, the smoke-collecting mechanism changes the range hood to its working mode to ensure good smoke extraction. However, as the range hood housing becomes thinner, the end of the connecting rod in the turned-on state cannot fully extend into the housing. This causes the hinge module of the connecting rod to protrude from the outside of the housing. The hinge module disconnects the oil circuit on the connecting rod, and when condensed oil accumulates to a certain level, it drips from the hinge module onto the cooktop below. Furthermore, this can lead to oil circuit failure, making it impossible to support the desired range hood design.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0036] like Figures 1-7As shown, this utility model embodiment provides a connecting rod oil guiding device, including a receiving plate 1, which includes a first region 101, a second region 102, and a third region 103 connected in sequence. The first region 101 of the receiving plate 1 has a receiving portion 11 at its front end, and the second region 102 of the receiving plate 1 has an upwardly extending connecting portion 12 at its top. The oil passage formed by the receiving plate 1 is such that the oil flows sequentially from the receiving portion 11 through the first region 101, the second region 102, and the third region 103, and then flows out through the third region 103. For clarity, definitions are used. Figure 1 The top of the middle is up, the bottom is down, the left is back, and the right is front.

[0037] like Figures 8-11As shown, the connecting rod oil guiding device provided in this embodiment of the present invention can be used on connecting rod structures 2 that are prone to oil buildup, such as the connecting rods of a range hood. The connecting rod structure 2 includes a first connecting rod 21 and a second connecting rod 22, the ends of which are hinged together by a hinge module 23 (e.g., a pivot). In use, the end of the second connecting rod 22 points forward, and the end of the first connecting rod 21 points backward. Along the direction from back to front, both the first connecting rod 21 and the second connecting rod 22 gradually rise in elevation. A receiving plate 1 is located at the bottom of the first connecting rod 21, a connecting part 12 is fixedly connected to the side of the first connecting rod 21, and a receiving part 11 is located below the hinge module 23, and is situated either to the side of the rear end of the second connecting rod 22 or below the rear end of the second connecting rod 22. Because the oil path from the second link 22 to the first link 21 is disconnected at the articulation module 23, the condensed oil will continuously accumulate at the rear end of the second link 22 and eventually drip down, causing external contamination. In addition, because the articulation module 23 protrudes from the surfaces of the first link 21 and the second link 22, the condensed oil will also continuously accumulate at the articulation module 23 and eventually drip down, causing external contamination. The connecting rod oil guiding device of this utility model can be set at the bottom of the first connecting rod 21. The receiving part 11 is located on the side of the rear end of the second connecting rod 22 or below the rear end of the second connecting rod 22. The bottom surface of the receiving part 11 is always lower than the bottom surface of the rear end of the second connecting rod 22. When the condensed oil accumulates at the rear end of the second connecting rod 22, it will be adsorbed onto the receiving part 11 (when the receiving part 11 is located on the side of the rear end of the second connecting rod 22) or drip directly onto the receiving part 11 (when the receiving part 11 is located below the rear end of the second connecting rod 22) under the action of gravity. Under the action of gravity, it flows along the bottom of the receiving plate 1 towards the first connecting rod 21 and finally drips from the rear end of the receiving plate 1, for example, dripping into the inside of the range hood, thereby avoiding the condensed oil from dripping to the outside and causing pollution. In addition, the receiving part 11 can also catch the condensed oil accumulated on the protruding part of the hinge module 23 from below, and then flow along the bottom of the receiving plate 1 towards the first connecting rod 21 under the action of gravity, and finally drip from the rear end of the receiving plate 1, for example, dripping into the inside of the range hood, thus preventing the condensed oil from dripping to the outside and causing pollution. Finally, when the condensed oil at the bottom of the first connecting rod 21 accidentally falls, it can also be caught by the receiving plate 1 below and drip from the rear end of the receiving plate 1, for example, dripping into the inside of the range hood, thus preventing the condensed oil from dripping to the outside and causing pollution. The connecting rod oil guiding device provided in this embodiment of the utility model can conduct the oil passages of the connecting rods on both sides of the hinge module, thereby solving the oil dripping problem. It has a simple structure, only needs to be fixed to the first connecting rod during installation, is easy to install, and has strong versatility.

[0038] like Figures 1-7As shown, in one embodiment of this utility model, the longitudinal section of the receiving part 11 is a downwardly concave arc shape. The arc shape of the longitudinal section of the receiving part 11 ensures that the first connecting rod 21 can receive the condensed oil droplets from the hinge module during movement, preventing them from flowing out. Furthermore, when the receiving part 11 is located on the rear side of the second connecting rod 22, it also ensures a large overlap area between the receiving part 11 and the second connecting rod 22. Even when the angle between the second connecting rod 22 and the horizontal plane fluctuates within the range of 6 to 20°, there is still an overlap area, thus still achieving the aforementioned oil guiding function. Therefore, it can adapt to connecting rods with different opening angles, exhibiting strong versatility.

[0039] like Figures 1-7 As shown, in one embodiment of this utility model, the connecting part 12 is provided with a connecting hole 13 to facilitate a detachable and quick connection with the first connecting rod 21 via a connector (such as a bolt). Furthermore, the connecting part 12 is located on one side of the receiving plate 1, so that the top surface of the receiving plate 1 can be positioned as far below the first connecting rod 21 and the hinge module 23 as possible, improving the effect of receiving condensate oil. To ensure the stability of the connection, the number of connecting parts 12 can be at least two, and the connecting parts 12 are distributed along the length direction of the receiving plate 1. In this embodiment, the number of connecting parts 12 is two.

[0040] like Figures 1-7 As shown, in order to facilitate the dripping of oil from the rear end of the receiving plate 1, in one embodiment of the present invention, the rear end of the third region 103 of the receiving plate 1 gradually tapers inward to form a pointed tip.

[0041] In order to reduce costs, in one embodiment of this utility model, the connecting rod oil guiding device is a plastic component.

[0042] like Figures 8-11 As shown, this utility model also provides a connecting rod structure, including the aforementioned connecting rod oil guiding device, and further including a first connecting rod 21 and a second connecting rod 22, with the second connecting rod 22 located in front of the first connecting rod 21. The ends of the first connecting rod 21 and the second connecting rod 22 are hinged together by a hinge module 23. The receiving plate 1 is disposed at the bottom of the first connecting rod 21, and the connecting part 12 is fixedly connected to the side of the first connecting rod 21. The receiving part 11 is disposed below the hinge module 23, and the receiving part 11 is located to the side or below the rear end of the second connecting rod 22. For clarity, the direction in which the end of the second connecting rod 22 points is defined as forward, and the direction in which the end of the first connecting rod 21 points is defined as backward. In use, along the direction from back to front, both the first connecting rod 21 and the second connecting rod 22 gradually rise in an upward form. In addition, the bottom surface of the rear end of the second connecting rod 22 is lower than the bottom surface of the first connecting rod 21. In this embodiment, the hinge module 23 is a rotating shaft.

[0043] like Figures 8-11As shown, the linkage structure provided by this utility model allows condensed oil to accumulate at the rear end of the second linkage 22. Under the action of surface tension, the oil droplets are adsorbed onto the receiving part 11 (when the receiving part 11 is located to the side of the rear end of the second linkage 22) or drip directly onto the receiving part 11 (when the receiving part 11 is located below the rear end of the second linkage 22). Under the action of gravity, the oil flows along the bottom of the receiving plate 1 towards the first linkage 21 and eventually drips from the rear end of the receiving plate 1, for example, into the interior of the range hood, thus preventing condensed oil from dripping externally and causing pollution. Additionally, the receiving part 11 can also catch the condensed oil accumulated at the protruding portion of the hinge module 23 from below, allowing it to flow along the bottom of the receiving plate 1 towards the first linkage 21 under gravity and eventually drip from the rear end of the receiving plate 1, for example, into the interior of the range hood, thus preventing condensed oil from dripping externally and causing pollution. Finally, if the condensed oil at the bottom of the first connecting rod 21 accidentally falls, it can be caught by the receiving plate 1 below and drip from the rear end of the receiving plate 1, for example, dripping into the inside of the range hood, thus preventing the condensed oil from dripping to the outside and causing pollution. The connecting rod structure provided in this embodiment of the utility model can guide the oil path flowing from the second connecting rod 22 to the first connecting rod 21, thereby solving the oil dripping problem. It has a simple structure and strong versatility.

[0044] like Figure 11 As shown, in one embodiment of this utility model, the receiving part 11 is located on the rear end side of the second connecting rod 22, and the bottom surface of the receiving part 11 is lower than the bottom surface of the rear end of the second connecting rod 22. A first gap exists between the first connecting rod 21 and the second connecting rod 22, and a second gap exists between the receiving plate 1 and the second connecting rod 22. The width of the second gap is smaller than the width of the first gap. In this embodiment, the receiving part 11 can further reduce the initial gap (first gap) between the first connecting rod 21 and the second connecting rod 22, and its bottom surface is always lower than the bottom surface of the rear end of the second connecting rod 22. When condensed oil accumulates at the rear end of the second connecting rod 22, it is easily adsorbed onto the receiving part 11 under the action of surface tension of the oil droplets.

[0045] like Figures 8-11 As shown, in one embodiment of this utility model, the front end of the first connecting rod 21 is hinged to the rear end of the second connecting rod 22 to avoid the rear end of the second connecting rod 22 from being separated from the hinge module 23, so that the stroke is too large during rotation and it is not easy to guide the condensed oil into the receiving part 11.

[0046] This utility model also provides a range hood, including the aforementioned linkage structure and a housing (not shown in the figure). The housing has an air inlet, and a flap is provided outside the air inlet. The rear end of the first linkage 21 is connected to the housing, and the front end of the second linkage 22 is connected to the flap, allowing the flap to move between a first position and a second position. When the flap is in the first position, it blocks the air inlet; when it is in the second position, it moves away from the air inlet. The linkage connecting the flap to the housing of the range hood is prior art and will not be described further. The range hood also includes a drive component 3 for moving the first linkage, which is prior art and will not be described further. The range hood provided by this utility model embodiment can guide the oil flow from the second linkage 22 to the first linkage 21, thereby solving the oil dripping problem and enabling an ultra-thin housing design. Furthermore, the enclosure is an ultra-thin enclosure, and when the flap is in the second position, the hinge module 23 is located on the outside of the enclosure.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
