Description

Technical Field

[0001] This utility model relates to an oil cup and a range hood that uses the oil cup. Background Technology

[0002] Range hoods typically have an oil cup at the bottom to collect grease. Existing oil cups often employ a horizontally movable, plug-and-play structure for installation at the bottom of the range hood body. For example, the Chinese utility model patent "Long Strip Oil Cup and Range Hood" (CN211551721U, application number 201921465650.8) discloses an oil cup that uses a horizontally movable method for installation. This type of oil cup is usually exposed at the bottom of the range hood, providing ample horizontal operating space. However, as users' demands for aesthetically pleasing range hoods have increased, some range hoods have begun to conceal the oil cup at the bottom. Due to the need for concealed installation, the oil cup is obstructed by an external baffle, limiting sufficient horizontal movement space. This makes the current horizontally movable plug-and-play solution unsuitable for range hoods with concealed oil cup installations. Utility Model Content

[0003] The first technical problem to be solved by this utility model is to provide an oil cup that is low in cost, can be vertically disassembled and assembled, and is easy to hide inside a range hood, in contrast to the above-mentioned prior art.

[0004] The second technical problem to be solved by this utility model is to provide a range hood with a concealed oil cup and an aesthetically pleasing overall appearance, in contrast to the above-mentioned prior art.

[0005] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: an oil cup, which is set in the lower part of the machine body and includes a cup body. The feature is that it also includes a connecting component, which includes a fixing member, a movable member, and a connecting member. The fixing member has a cavity with a downward opening. The movable member is movably set in the cavity of the fixing member. The connecting member is set at the lower end of the movable member. The cup body is detachably connected to the connecting member.

[0006] In order to enable the connector to automatically open and close relative to the movable part based on the descent and rise of the movable part, and further realize the locking and unlocking action of the cup body, simplifying the user operation, the connector is rotatably connected to the movable part by a torsion spring. The connector has a tendency to separate and open relative to the movable part based on the elastic force of the torsion spring. As the movable part moves upward, the connector moves closer to the movable part under the constraint of the cavity.

[0007] The cup body is provided with a connecting part, which is sandwiched between the movable part and the connecting part based on the relative proximity of the connecting part and the movable part.

[0008] To effectively prevent the cup from falling due to accidental contact, the connecting part of the cup includes a horizontally arranged connecting plate, and the connecting member includes a snap-fit ​​plate. The snap-fit ​​plate flips up to the bottom of the movable member as the movable member moves upward, so as to clamp the connecting plate between the bottom surface of the movable member and the snap-fit ​​plate.

[0009] In order to effectively achieve the positioning of the cup body in both the use and disassembly states, the inner wall of the cavity of the fixing component is provided with a guide groove that can constrain the positioning of the movable component relative to the fixing component, and the movable component is provided with a positioning rod that is inserted into the guide groove.

[0010] To ensure that the positioning rod can swing freely within the guide rail groove based on the direction of the guide rail groove, the positioning rod is Z-shaped, with one end of the positioning rod passing through the movable part and the other end of the positioning rod inserted into the guide rail groove.

[0011] With a simple structure, the guide rail groove includes a first guide rail segment and a second guide rail segment. The first guide rail segment is V-shaped and the second guide rail segment is W-shaped. The first guide rail segment is located outside the second guide rail segment, and the two ends of the first guide rail segment and the second guide rail segment are respectively connected.

[0012] In order to provide downward pressure to the positioning rod so that it always fits against the motion track and ensures the stability of the motion, an elastic element is provided between the upper end of the movable part and the inner top surface of the cavity. The elastic element has a tendency to press down on the movable part.

[0013] To facilitate component assembly, the fastener includes a first component and a second component that are relatively mating.

[0014] To ensure the balance of cup assembly and disassembly, the connecting components include two sets, which are respectively located at the left and right ends of the machine body, and the left and right ends of the cup body are respectively connected to the connecting components at the corresponding ends.

[0015] The technical solution adopted by this utility model to solve the second technical problem mentioned above is as follows: a range hood, including a body and a baffle disposed on the front side of the body, and also including the aforementioned oil cup, wherein the cup is detachably connected to the lower part of the body and located behind the baffle via a connecting component.

[0016] Compared with the prior art, the advantages of this utility model are as follows: The oil cup in this utility model can be connected to the movable part through a connector, and based on the cooperation between the fixed part and the movable part in the connection structure, it can move up and down relative to the body as the movable part moves up and down. In this way, it is convenient to hide the oil cup at the bottom of the range hood body. When it is necessary to remove the cup, the downward movement of the movable part can expose the cup from the bottom of the body, thus facilitating the removal or installation of the cup.

[0017] Range hoods using this oil cup can have the cup concealed within the machine body, improving the overall aesthetics of the range hood and making it easy to remove and clean. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 6 As shown, the oil cup in this embodiment is located at the lower part of the machine body 100. The oil cup includes a cup body 1 and a connecting component 200.

[0026] The connecting assembly 200 includes a fixing member 2, a movable member 3, and a connecting member 4. The fixing member 2 is fixedly mounted on the body 100 and has a downward-opening cavity 21. The movable member 3 is movably mounted within the cavity 21 of the fixing member 2. The connecting member 4 is located at the lower end of the movable member 3, and the cup body 1 is detachably connected to the connecting member 4. Thus, based on the up-and-down movement of the movable member 3, the cup body 1 can also move up and down relative to the body 100, thereby facilitating its movement behind the baffle 300 on the front side of the body 100, ensuring the overall aesthetics of the range hood when the oil cup is in use, or allowing it to protrude below the baffle 300 on the front side of the body 100, making it easy for the user to remove the cup body 1.

[0027] The elongated cup body 1 is a common oil cup structure in range hoods. If only one set of connecting components 200 is used to connect the cup body 1, its vertical movement stability is poor. To improve the stability of the vertical movement of the cup body 1, at least two sets of connecting components 200 can be provided. In this embodiment, the connecting components 200 include two sets, which are respectively located at the left and right ends of the body 100. The left and right ends of the cup body 1 are respectively connected to the connecting components 200 at the corresponding ends. The structure of each set of connecting components 200 is the same and they are symmetrically arranged at the left and right ends of the body 100. Specifically, the fixing members 2 in the two sets of connecting components 200 are respectively fixedly located inside the left and right ends of the body 100. As the movable member 3 moves downward relative to the fixing member 2, the movable member 3 can be exposed below the body 100, causing the cup body 1 to be exposed below the baffle 300 on the front side of the body 100.

[0028] The connector 4 in the connecting assembly 200 is used to realize the connection and disassembly of the cup body 1 on the movable part 3. Simply put, the connector 4 can use a hook. However, using a hook cannot guarantee the connection stability of the cup body 1 on the movable part 3. In addition, the operation of assembling and disassembling the oil cup is relatively complicated.

[0029] In this embodiment, the connecting member 4 can lock the cup body 1 based on the rising of the movable member 3, and can automatically release the cup body 1 based on the falling of the movable member 3. Specifically, the connecting member 4 is rotatably connected to the movable member 3 by a torsion spring 5. The connecting member 4 tends to separate and open relative to the movable member 3 based on the elastic force of the torsion spring 5. As the movable member 3 moves upward, the connecting member 4 moves closer to the movable member 3 under the constraint of the cavity 21. In addition, the cup body 1 is provided with a connecting part 11, which is clamped between the movable member 3 and the connecting member 4 based on the relative proximity of the connecting member 4 and the movable member 3. Specifically, when the movable member 3 moves upward relative to the fixed member 2, the connecting member 4 can overcome the elastic force of the torsion spring 5 and retract into the cavity 21 of the fixed member 2. Based on the constraint of the cavity 21, it moves closer to the movable member 3, thereby clamping the connecting part 11 of the cup body 1 between the movable member 3 and the connecting member 4, thus realizing the connection of the cup body 1 to the movable member 3. When the movable part 3 moves downward relative to the fixed part 2, the connecting part 4, as the movable part 3 protrudes out of the cavity 21, opens away from the movable part 3 based on the elastic force of the torsion spring 5, thereby releasing the connecting part 11 of the cup body 1 and realizing the detachment of the cup body 1 from the connecting assembly 200. Based on the specific structure of the connecting part 4 relative to the movable part 3 in this embodiment, the connecting part 4 can automatically realize the opening and closing action relative to the movable part 3 as the movable part 3 descends and rises, further realizing the locking and loosening action of the cup body 1, simplifying the user operation, and the user no longer needs to perform additional actions of suspending and disassembling the cup body 1 relative to the connecting part 4.

[0030] If the clamping of the connecting part 11 in the cup body 1 is achieved vertically, it is easy for it to fall off due to accidental contact. Therefore, in this embodiment, the clamping of the connecting part 11 in the cup body 1 is achieved horizontally, so that the cup body 1 can be stably connected to the movable part 3 and avoid falling off due to accidental contact. Specifically, the connecting part 11 of the cup body 1 includes a horizontally arranged connecting plate 111, that is, part of the side plate of the cup body 1 is bent upward and horizontally to form the connecting plate 111. The connecting part 4 includes a snap-fit ​​plate 41, which flips to the bottom of the movable part 3 as the movable part 3 moves upward, so as to clamp the connecting plate 111 between the bottom surface of the movable part 3 and the snap-fit ​​plate 41. Specifically, the connecting part 4 is a plate structure with an L-shaped cross section, wherein the vertical plate part is rotatably connected to the movable part 3, while the horizontal plate part constitutes the snap-fit ​​plate 41, which is used to cooperate with the connecting plate 111 to lock the cup body 1. When the cup body 1 needs to be installed, the movable part 3 moves down and is exposed outside the cavity 21 of the fixed part 2. At this time, the connecting part 4 is in an inclined state due to the elastic force of the torsion spring 5, that is, the vertical plate part of the connecting part 4 is inclined relative to the vertical, and the snap-fit ​​plate 41 is inclined downward relative to the horizontal. At this time, there is a large gap between the snap-fit ​​plate 41 and the bottom surface of the movable part 3. The user holds the cup body 1, puts the connecting part 11 on the cup body 1 against the bottom surface of the movable part 3, and then places it between the bottom surface of the movable part 3 and the connecting plate 111. Then the user pushes the cup body 1 upward. The movable part 3 is pushed upwards simultaneously. As the movable part 3 continues to rise, the connecting part 4 overcomes the elastic force of the torsion spring 5 and moves closer to the movable part 3. When the movable part 3 is in place, the snap-fit ​​plate 41 in the connecting part 4 clamps the connecting plate 111 from below between the bottom surface of the movable part 3 and the snap-fit ​​plate 41, thus connecting the cup body 1 to the movable part 3. At the same time, the cup body 1 is also in its highest position, thus hiding behind the baffle 300 located below the body 100 and on the front side of the body 100, achieving the hidden installation of the cup body 1. When it is necessary to remove the cup body 1 from the movable part 3, the user holds the cup body 1. As the movable part 3 moves downwards relative to the fixed part 2, the connecting part 4, based on the action of the torsion spring 5, gradually opens away from the movable part 3. Then, the snap-fit ​​plate 41 releases its clamping on the connecting plate 111. After the movable part 3 moves downwards to its position, the connecting part 4 is fully opened relative to the movable part 3, and the cup body 1 automatically detaches from the movable part 3.

[0031] Based on the aforementioned description of the oil cup assembly and removal operations, while the movable part 3 can move up and down relative to the fixed part 2, after the movable part 3 moves up or down to its designated position, it also needs to be stabilized at that position. This necessitates an additional structure to position the movable part 3 relative to the fixed part 2. A simple solution would be to use an electric drive to achieve this movement; however, electric drive structures are costly and space-consuming, impacting the internal layout of the range hood.

[0032] Of course, in the simplest case, the moving part 3 can be made of a material with a high coefficient of friction, and the position of the moving part 3 relative to the fixed part 2 can be maintained by the friction between the moving part 3 and the fixed part 2, but this structure is unreliable.

[0033] In addition, the relative positioning structure of the fixed part 2 and the movable part 3 can also adopt the following structure: the inner wall of the cavity 21 of the fixed part 2 is provided with positioning grooves at the highest and lowest positions, and the movable part 3 is connected to a positioning post by a spring. The positioning of the movable part 3 relative to the fixed part 2 is achieved by the positioning post engaging with the corresponding positioning groove. However, this structure is prone to jamming during vertical movement, and the spring is also prone to fatigue and positioning failure during long-term use.

[0034] To ensure the smooth movement of the movable part 3 relative to the fixed part 2, and to guarantee the long-term reliability of the relative positioning of the fixed part 2 and the movable part 3, in this embodiment, the inner wall of the cavity 21 of the fixed part 2 is provided with a guide groove 22 for positioning the movable part 3 relative to the fixed part 2. The movable part 3 is provided with a positioning rod 6 that is inserted into the guide groove 22. The guide groove 22 includes a first guide section 221 and a second guide section 222. The first guide section 221 is V-shaped, and the second guide section 222 is W-shaped. The first guide section 221 is located outside the second guide section 222, and the two ends of the first guide section 221 and the second guide section 222 are respectively connected to form a closed loop guide groove 22. The height of the first guide section 221 matches the height difference between the highest and lowest positions of the movable part 3 relative to the fixed part 2, and the overall height of the second guide section 222 is much smaller than the height of the first guide section 221.

[0035] For ease of description, the lowest bend of the first guide rail segment 221 is defined as the starting point 223, the connection point between the first guide rail segment 221 and one end of the second guide rail segment 222 is defined as the release point 224, and the connection point between the other end of the first guide rail segment 221 and the second guide rail segment 222 is defined as the inflection point 225. In the W-shaped second guide rail segment 222, the lower bend near the release point 224 is defined as the unlocking point 226, the lower bend near the inflection point 225 is defined as the locking point 227, and the upper bend in the second guide rail segment 222 is defined as the middle release point 228.

[0036] In use, when the movable part 3 is in its lowest position relative to the fixed part 2, the positioning rod 6 is located at the starting point 223 of the guide rail groove 22. At this time, the connecting part 4 is open relative to the movable part 3, allowing the connecting part 11 of the cup body 1 to be pushed upwards towards the bottom surface of the movable part 3. As the movable part 3 moves upwards relative to the fixed part 2, the positioning rod 6 gradually moves along one side of the first guide rail section 221 to the inflection point 225. The user can then release the cup body 1. Based on the downward pressing force of the elastic member 7 on the movable part 3, the positioning rod 6 moves along the second guide rail section 222 to the locking point 227. At this time, the movable part 3 is stably positioned relative to the fixed part 2. Correspondingly, the connecting part 4 is constrained within the cavity 21 and cooperates with the movable part 3 to clamp the connecting part 11 on the cup body 1, completing the installation of the cup body 1. The cup body 1 is in a high position and can be hidden behind the baffle 300 on the front side of the machine body 100. When it is necessary to remove the cup body 1, the user pushes the cup body 1 upward from the lower part of the body 100. The movable part 3 moves upward with the cup body 1. At this time, the positioning rod 6 moves along the second guide rail section 222 to the middle release point 228. After the user releases the upward pushing force on the cup body 1, under the action of the elastic member 7, the positioning rod 6 continues to move along the second guide rail section 222 to the unlocking point 226. At this time, since the unlocking point 226 is basically at the same height as the cup body 1, the connecting part 4 still maintains the locking effect on the connecting part 11 of the cup body 1 based on the restriction of the cavity 21. The user can push the cup body 1 upward again, causing the movable part 3 to move upward. The corresponding positioning rod 6 moves along the second guide rail section 222 to the release point 224. Then the user releases the upward pushing force on the cup body 1. Under the action of the elastic member 7, the positioning rod 6 moves to the other side of the first guide rail section 221 and moves down to the starting point 223. At this time, the lower part of the movable part 3 is exposed outside the fixed member 2. The corresponding connecting member 4 opens the lock on the cup body 1 relative to the movable part 3 based on the action of the torsion spring 5. At this time, the cup body 1 can be taken away.

[0037] Based on the W-shape of the second guide rail segment 222, the second guide rail segment 222 has two downward bending positions, which avoids the problem of the cup body 1 falling off due to accidental upward contact, and improves the reliability of the connection of the cup body 1 on the moving part 3.

[0038] In order to ensure that the positioning rod 6 can swing freely within the guide rail groove 22 based on the direction of the guide rail groove 22, the positioning rod 6 is Z-shaped. One end of the positioning rod 6 is inserted through the movable part 3, and the other end of the positioning rod 6 is placed in the guide rail groove 22. As the positioning rod 6 is placed in different positions within the guide rail groove 22, the positioning rod 6 swings adaptively.

[0039] In addition, an elastic element 7 is provided between the upper end of the movable part 3 and the inner top surface of the cavity 21. The elastic element 7 has a tendency to press down on the movable part 3. Based on the elastic element 7, the unidirectional movement of the positioning rod 6 relative to the guide rail groove 22 can be guaranteed. At the same time, it can ensure that the swing rod does not derail when it moves in a closed loop in the guide rail groove 22. In addition to satisfying the reciprocating motion of the movable part 3, the spring also provides a downward force to the positioning rod 6, so that it always fits in contact with the movement track and ensures the stability of the movement.

[0040] To facilitate the assembly of components such as movable part 3, connecting part 4, torsion spring 5, and elastic part 7 within the cavity 21, in this embodiment, the fixing part 2 includes a first component 23 and a second component 24 that are relatively mated. During installation, the movable part 3, connecting part 4, torsion spring 5, and elastic part 7 are first assembled into one of the components, and then the other component is mated and connected to that component.

[0041] The oil cup in this invention can be connected to the movable part 3 via the connector 4. Based on the cooperation between the fixed part 2 and the movable part 3 in the connection structure, it can move up and down relative to the body 100 as the movable part 3 moves up and down. In this way, the oil cup can be hidden and installed at the bottom of the range hood body 100. When it is necessary to remove the cup body 1, the downward movement of the movable part 3 can expose the cup body 1 from the bottom of the body 100, thereby facilitating the removal or installation of the cup body 1.

[0042] Meanwhile, the up-and-down movement of the cup body 1 only requires simple manual operation, without the need for an additional power source, which reduces the cost of the connecting component 200. Furthermore, the connecting component 200 occupies less space within the body 100.

[0043] The oil cup in this embodiment can be applied to range hoods of various structures, and is especially suitable for range hoods where the oil cup needs to be installed in a concealed manner.

[0044] The range hood in this embodiment is a type of range hood that requires a concealed installation of the oil cup. The range hood includes a body 100, a baffle 300 located on the front side of the body 100, and the aforementioned oil cup. The cup body 1 is detachably connected to the lower part of the body 100 and located behind the baffle 300 via a connecting assembly 200. The baffle 300 on the front side of the body 100 can cover the front of the cup body 1. No space needs to be reserved in front of the cup body 1 for it to be removed forward. When the oil cup needs to be removed, the aforementioned operation causes the movable part 3 in the connecting assembly 200 to move downwards, thereby exposing the cup body 1 below the baffle 300, making it easy to remove the cup body 1.

[0045] Based on the structural characteristics of the oil cup, this oil cup is particularly suitable for installation on range hoods that require the oil cup to be concealed on the body 100. After concealed installation, the oil cup is not visible from the front of the range hood, greatly improving the overall aesthetics of the range hood. At the same time, the downward movement of the movable part 3 allows the cup body 1 to be exposed below the baffle 300, making it easier for the user to remove the cup body 1.

[0046] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of the invention. However, the use of these terms is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
