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 CN211551721U (application number 201921465650.8), entitled "Long Strip Oil Cup and Range Hood," 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, obstructed by an external baffle, lacks sufficient horizontal movement space. This makes the current purely 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 simple in structure, reliable in installation, occupies little space, requires no additional power source, and can be installed in the range hood in a vertically concealed manner.

[0004] The second technical problem to be solved by this utility model is to provide a range hood that is low in cost, has a convenient hidden oil cup for easy disassembly and assembly, and has 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 disposed below the machine body, includes a cup body and a connecting component disposed at the lower part of the machine body; the connecting component includes a first component disposed on the machine body and a second component disposed on the first component that moves up and down, and the cup body is detachably connected to the lower end of the second component.

[0006] To ensure the smooth up-and-down movement of the cup, the connecting components include two sets, which are respectively located on the left and right sides of the machine body, and the left and right ends of the cup body are respectively connected to the connecting components on the corresponding sides.

[0007] To facilitate the handling of the cup, the lower end of the second component is provided with a forward-opening snap-fit ​​groove, and the cup is provided with a snap-fit ​​plate that matches and is placed in the snap-fit ​​groove.

[0008] Preferably, the second component is provided with a connecting plate, and part of the connecting plate is bent to the lower part of the second component to form the snap-fit ​​groove between it and the lower end surface of the second component.

[0009] To ensure the cup body is firmly connected to the second component, the second component is provided with a mounting groove facing the opening of the snap-fit ​​groove. The mounting groove is provided with a first elastic member and a pressing member. The first elastic member is disposed between the pressing member and the upper wall of the snap-fit ​​groove, and the first elastic member has a tendency to press the pressing member downward.

[0010] To further enhance the firmness of the connection between the cup body and the second component, and to facilitate the disassembly of the cup body, the snap-fit ​​plate is provided with an opening into which the pressing member can be inserted, and the longitudinal section of the pressing member in the front-back direction is conical.

[0011] In order to provide guidance for the vertical movement of the second component and improve the stability of the vertical movement of the cup, the first component has a cavity extending vertically, and the second component is disposed vertically within the cavity.

[0012] The structure is simple. The inner wall of the cavity of the first component is provided with a guide rail groove with unidirectional circulation guidance, and the second component is provided with a positioning rod whose end can be inserted into the guide rail groove.

[0013] The guide rail groove includes a first guide rail segment, a second guide rail segment, a third guide rail segment, and a fourth guide rail segment connected in sequence. The first and fourth guide rail segments are arranged in a V-shape and connected at their lower ends. The connection point of the first and fourth guide rail segments forms the starting point of the guide rail groove. The second and third guide rail segments are also arranged in a V-shape and connected at their lower ends. The connection point of the second and third guide rail segments forms the locking point of the guide rail groove, which is located above the starting point. The upper ends of the first and second guide rail segments are connected, forming a first inflection point at the connection point. The upper ends of the third and fourth guide rail segments are connected, forming a second inflection point at the connection point. Both the first and second inflection points are located above the locking point.

[0014] In order to make the positioning rod fit more closely with the guide rail groove, so as to realize the cyclic movement of the positioning rod in the guide rail groove and ensure the stability of the cup body's up and down movement, a second elastic element is provided between the upper end of the second component and the top wall of the cavity. The second elastic element has a tendency to press the second component downward.

[0015] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a range hood, including a body and the aforementioned oil cup, wherein the cup is installed in the lower part of the body in a way that allows it to move up and down through 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 is mounted on the machine body by moving the cup body in the vertical direction based on the connecting component. In this way, the oil cup can be hidden and installed at the bottom of the range hood body. When it is necessary to remove the cup body, the cup body can be exposed from the bottom of the machine body by moving the second component in the connecting component downward, which makes it easy to remove the cup body.

[0017] Range hoods using this oil cup can have the oil 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, in this embodiment, the oil cup is located at the lower part of the machine body 100. The oil cup includes a cup body 1 and a connecting component located at the lower part of the machine body 100.

[0026] The oil cup is set according to the specific model of the range hood.

[0027] The connecting assembly includes a first component 2 disposed on the body 100 and a second component 3 disposed on the first component 2 that moves up and down. The cup body 1 is detachably connected to the lower end of the second component 3.

[0028] When installing the oil cup, connect the cup body 1 to the lower end of the second component 3, and push the cup body 1 upwards so that the cup body 1 and the second component 3 move upwards relative to the first component 2. After moving upwards into position, the cup body 1 is in the working position relative to the machine body 100, thus enabling the collection of oil stains. When it is necessary to remove the cup body 1 for cleaning, move the second component 3 downwards. The second component 3 and the cup body 1 move downwards synchronously. After moving downwards into position, the cup body 1 will be exposed below the machine body 100. At this time, the cup body 1 can be removed from the second component 3.

[0029] The connecting component provides the cup body 1 with the function of moving up and down relative to the body 100, which provides convenience for the range hood with the oil cup installed in a hidden manner. The cup body 1 can be hidden behind the front baffle of the body 100 or exposed below the front baffle based on the up and down movement.

[0030] The elongated cup body 1 is a common oil cup structure in range hoods. If only one set of connecting components is used to connect the cup body 1, its vertical movement stability is poor. To improve the stability of the cup body 1's vertical movement, at least two sets of connecting components can be provided. In this embodiment, the connecting components include two sets, respectively located on the left and right sides of the body 100, with the left and right ends of the cup body 1 connected to the corresponding connecting components. Each set of connecting components has the same structure and is symmetrically arranged on the left and right sides of the body 100. Specifically, the first component 2 in each of the two sets of connecting components is fixedly installed inside the left and right sides of the body 100.

[0031] In assembling and removing the cup body 1, the lower part of the second component 3 relative to the first component 2 is moved downwards, so that the lower end of the second component 3 is exposed below the body 100, thereby facilitating the user to install the cup body 1 on the second component 3 or remove the cup body 1 from the second component 3. To reduce the difficulty of assembling and disassembling the cup body 1 on the second component 3, the lower end of the second component 3 is provided with a forward-opening snap-fit ​​groove 31, and the cup body 1 is provided with a snap-fit ​​plate 11 that matches and is placed in the snap-fit ​​groove 31. Specifically, the second component 3 is provided with a connecting plate 32, and part of the connecting plate 32 is bent outwards to the lower part of the second component 3 to form a snap-fit ​​groove 31 between it and the lower end surface of the second component 3. The side plates on the left and right sides of the cup body 1 are bent horizontally to form snap-fit ​​plates 11. When installing the cup body 1 on the second component 3, the snap-fit ​​plate 11 on the cup body 1 is inserted into the snap-fit ​​groove 31 from front to back, thus realizing the installation of the cup body 1 on the second component 3. To prevent the cup body 1 from falling off the second component 3, the rear side of the connecting plate 32 can be bent upward to form a limiting surface, which serves to limit the backward movement of the locking plate 11. When it is necessary to remove the cup body 1 from the second component 3, hold the cup body 1 and move it forward to move the locking plate 11 forward out of the locking groove 31, thus removing the cup body 1.

[0032] However, relying solely on the interaction between the snap-fit ​​groove 31 and the snap-fit ​​plate 11 can easily lead to the risk of the cup body 1 falling off. To address this issue, in this embodiment, the second component 3 is provided with an installation groove 33 facing the opening of the snap-fit ​​groove 31. The installation groove 33 contains a first elastic member 4 and a pressing member 5. The first elastic member 4 is positioned between the pressing member 5 and the upper wall of the snap-fit ​​groove 31, and it has a tendency to push the pressing member 5 downwards. Thus, when the snap-fit ​​plate 11 is inserted into the snap-fit ​​groove 31, the pressing member 5 presses against the snap-fit ​​plate 11 under the action of the first elastic member 4, ensuring the stability of the snap-fit ​​plate 11 within the snap-fit ​​groove 31. To further enhance the firmness of the connection between the cup body 1 and the second component 3, and to facilitate the disassembly of the cup body 1, in this embodiment, an opening 111 is also provided on the snap-fit ​​plate 11 for the pressing member 5 to abut. The longitudinal section of the pressing member 5 is tapered. This tapered structure facilitates the mounting plate 11 to overcome the pressing force of the pressing member 5 and be assembled into or removed from the mounting groove 31. When the mounting plate 11 is placed in the mounting groove 31, under the elastic force of the first elastic member 4, the pressing member 5 presses against the opening 111 of the mounting plate 11, thereby better ensuring the stability of the mounting plate 11 in the mounting groove 31. Only when the user applies a large force can the mounting plate 11 overcome the pressure of the pressing member 5 and move. Other occasional contact with the cup body 1 cannot move the position of the cup body 1 relative to the second member 3, thus effectively solving the risk of the cup body 1 falling off.

[0033] The first component 2 has a cavity 21 extending vertically, and the second component 3 is movably disposed in the cavity 21. The cavity 21 provides vertical guidance for the second component 3, thereby improving the stability of the second component 3 moving vertically relative to the first component 2, and thus improving the stability of the cup body 1 moving vertically.

[0034] To ensure that the second component 3 remains in the working position when the cup body 1 is in use, and in the disassembly / assembly position when the cup body 1 is disassembled, the first component 2 and the second component 3 can employ various existing structures capable of vertical movement and positioning. For example, the second component 3 and the first component 2 can be installed using a tight fit, with relative positioning achieved through friction between the first component 2 and the second component 3. Alternatively, the connecting component can employ a telescopic rod structure as used in existing technologies.

[0035] To facilitate operation and ensure the stability of the cup body 1 in both its working and disassembly positions, in this embodiment, the inner wall of the cavity 21 of the first component 2 is provided with a guide groove 22 that provides unidirectional circulation guidance, and the second component 3 is provided with a positioning rod 6 whose end can be inserted into the guide groove 22. The guide groove 22 provides two stopping positions for the positioning rod 6, thereby satisfying the need for the cup body 1 to remain in the working and disassembly positions. Specifically, the guide groove 22 includes a first guide section 221, a second guide section 222, a third guide section 223, and a fourth guide section 224 connected in sequence. The first guide section 221, the second guide section 222, the third guide section 223, and the fourth guide section 224 together form a V-shaped closed area. The specific connection relationship between the first guide rail segment 221, the second guide rail segment 222, the third guide rail segment 223, and the fourth guide rail segment 224 is as follows: the first guide rail segment 221 and the fourth guide rail segment 224 are arranged in a V-shape and connected at their lower ends; the connection point of the first guide rail segment 221 and the fourth guide rail segment 224 forms the starting point 225 of the guide rail groove 22. The second guide rail segment 222 and the third guide rail segment 223 are arranged in a V-shape and connected at their lower ends; the second guide rail segment 222, the second guide rail segment 223, the third guide rail segment 224, the fourth guide rail segment 224, the fifth guide rail segment 224, the sixth guide rail segment 224, the seventh guide rail segment 224, the eighth guide rail segment 224, the ninth guide rail segment 224, the eleventh guide rail segment 225, the eleventh guide rail segment 224 ... The connection of the three guide rail segments 223 forms a locking point 226 for the guide rail groove 22, which is located above the starting point 225. The upper ends of the first guide rail segment 221 and the second guide rail segment 222 are connected to form a first inflection point 227 at the connection. The upper ends of the third guide rail segment 223 and the fourth guide rail segment 224 are connected to form a second inflection point 228 at the connection. Both the first inflection point 227 and the second inflection point 228 are located above the locking point 226.

[0036] When the second component 3 is at its lowest position relative to the first component 2, the positioning rod 6 is located at the starting point 225 of the guide rail groove 22. After the cup body 1 is installed at the lower end of the second component 3, when it is necessary to move the cup body 1 upward and hide it inside the body 100, push the cup body 1 upward. The cup body 1 drives the second component 3 to move upward relative to the first component 2. At this time, the positioning rod 6 moves upward along the first guide rail section 221. When it reaches the first inflection point 227, the positioning rod 6 enters the second guide rail section 222. At this time, the user can release the cup body 1. The positioning rod 6 moves to the locking point 226 based on the guidance of the second guide rail section 222. The position of the first component 2 relative to the second component 3 is stable at this position. At this time, the cup body 1 is hidden inside the body 100. When it is necessary to remove the cup body 1, the user pushes the cup body 1 upward from the bottom of the body 100. The second component 3 moves upward with the cup body 1. At this time, the positioning rod 6 enters the third guide rail section 223. Under the guidance of the third guide rail section 223, the positioning rod 6 reaches the second inflection point 228. Then, the positioning rod 6 enters the fourth guide rail section 224. The user can release the cup body 1. Under the guidance of the fourth guide rail section 224, the positioning rod 6 moves downward along the fourth guide rail section 224. Correspondingly, the second component 3 moves downward relative to the first component 2. When the positioning rod 6 moves to the starting point 225, the positioning rod 6 stabilizes at the starting point 225. Correspondingly, the second component 3 remains stationary relative to the first component 2. At this time, the cup body 1 has moved to the position exposed above the body 100 as the second component 3 moves downward. The user can then proceed with the subsequent action of removing the cup body 1.

[0037] To facilitate the relative assembly of the first component 2 and the second component 3, the first component 2 in this embodiment includes two relatively mating component bodies. After the two component bodies are mated, they form the aforementioned cavity 21, and the guide groove 22 is provided on the inner wall of one of the component bodies.

[0038] In addition, a second elastic element 7 is provided between the upper end of the second component 3 and the top wall of the cavity 21. The second elastic element 7 has a tendency to press the second component 3 downward. Based on the elastic force of the second elastic element 7, when the user releases the upward pushing force on the cup body 1, the elastic force of the second spring can better overcome the friction between the positioning rod 6 and the inclined guide groove 22, driving the second component 3 to move downward. At the same time, based on the elastic force of the second spring, the positioning rod 6 on the second component 3 can better fit the guide groove 22, so as to realize the cyclic movement of the positioning rod 6 within the guide groove 22, ensuring the stability of the cup body 1's vertical movement.

[0039] In this utility model, the oil cup is mounted on the body 100 in a vertical direction by moving the cup body 1 along the connecting component. This makes it easy for the oil cup to be hidden and installed at the bottom of the body 100 of the range hood. When it is necessary to remove the cup body 1, the cup body 1 can be exposed from the bottom of the body 100 by moving the second component 3 in the connecting component downward, thus making it easy to remove the cup body 1.

[0040] 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 components. At the same time, the connecting components occupy little space within the body 100.

[0041] The oil cup in this embodiment can be applied to range hoods of various structures, and is particularly suitable for range hoods that require concealed installation of the oil cup. Specifically, the range hood in this embodiment includes a body 100 and the aforementioned oil cup. The cup body 1 is concealed in the lower part of the body 100 via a connecting assembly. That is, when the cup body 1 is in normal use, the baffle or other structures at the front of the body 100 can cover the front of the cup body 1, and no space needs to be reserved in front of the cup body 1 for it to be removed. When the oil cup needs to be removed, the second component 3 in the connecting assembly moves down through the aforementioned operation, thereby causing the cup body 1 to be exposed below the overall body 100, that is, below the baffle or other structures at the front of the body 100, thus facilitating the removal of the cup body 1.

[0042] Based on the characteristics of the oil cup, this oil cup is particularly suitable for installation in range hoods that require the oil cup to be concealed within 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 second component 3 allows the cup body 1 to be exposed below the body 100, making it easier to remove the cup body 1 from the second component 3.
