Description

Technical Field

[0001] The present disclosure relates to the technical field of range hoods, and in particular to an oil cup mounting structure of a range hood. Background Art

[0002] As a common household appliance in home kitchens, range hoods play a vital role in controlling the oil smoke generated during cooking. Range hoods are usually equipped with an oil cup, also known as an oil collection cup, which collects the oil droplets generated inside the range hood to prevent the oil droplets from falling onto the stove or kitchen utensils below.

[0003] In the traditional range hood design, the oil cup is connected to the slot at the bottom of the range hood through the ears on both sides of the top. The slot is close to the bottom of the range hood and is too narrow. The user needs to bend over to align the ears with the slot, which affects the user experience. At the same time, due to space limitations and obstructed vision, it is difficult for the user to accurately grasp the required force when installing or removing the oil cup, increasing the risk of deformation of the ears. Uneven strength of the left and right hands may also cause oil to spill and pollute the kitchen environment. Summary of the invention

[0037] Figure 1 A schematic diagram of an oil cup installation structure of a range hood according to an embodiment of the present disclosure is shown. Figure 1The oil cup installation structure of the range hood includes a body 1, an oil cup 2 and a lifting device 3. The lifting device 3 includes a linear drive module and a limit assembly. The lifting device 3 is used to drive the oil cup 2 to perform lifting and lowering movements. The limit assembly includes a slide rail 321, a first connecting rod 322, a second connecting rod 323 and a second limit component 324. The bottom of the linear drive module is fixedly connected to the middle of the first connecting rod 322, the two ends of the first connecting rod 322 are slidably connected to the slide rail 321, the first end of the second connecting rod 323 is fixedly connected to the first connecting rod 322, and the second end of the second connecting rod 323 is fixedly connected to the second limit component 324. The lifting device 3 allows the user to have sufficient operating space when installing and removing the oil cup 2, thereby reducing the difficulty of installing and removing the oil cup 2 for the user.

[0038] The first limiting components 21 are fixedly provided at both ends of the upper side of the oil cup 2. Figure 4 A schematic diagram showing the disassembly state of the oil cup and the limit assembly according to an embodiment of the present disclosure is shown as follows: Figure 4 The first stopper 21 is provided with a first protrusion extending downward. The second stopper 324 is provided with a groove matching the first protrusion, and the oil cup 2 is detachably connected to the second stopper 324. The matching design of the first stopper 21 and the second stopper 324 ensures the stability of the oil cup 2 during use, reduces the risk of oil spillage or accidental fall-off of the oil cup 2, and reduces the difficulty of users installing and removing the oil cup 2, thereby improving the user experience.

[0039] like Figure 4 A second protrusion is provided on the upper surface of the second limiting component 324, and the second protrusion matches the second end of the second connecting rod 323 and is used to limit the direction of the second limiting component 324 during installation. Figure 5 FIG. 1 shows a top view of a second position-limiting component according to an embodiment of the present disclosure. The present disclosure does not limit the shape of the second protrusion. In one embodiment, as shown in FIG. Figure 5 The second protrusion is two semicircular protrusions. The matching design of the second protrusion and the second connecting rod 323 ensures that the second limiting component 324 is in the correct direction during the installation process, avoids the deviation of the installation position, provides an intuitive installation guide for the installer, and makes the installation process simpler and faster.

[0040] like Figure 1 A first opening is provided at the bottom of the body 1, and the second end of the second connecting rod 323 passes through the first opening and is fixedly connected to the second limiting component 324, and the second connecting rod 323 is symmetrically distributed on both sides of the oil cup 2. The second connecting rod 323 is symmetrically distributed on both sides of the oil cup 2, which helps to maintain the balance of the oil cup 2 and avoid shaking or tilting due to uneven weight.

[0041] like Figure 4The limiting assembly also includes a locking member 325. The locking member 325 is located above the second limiting member 324. The thickness of the locking member 325 is greater than the thickness of the edge of the first limiting member 21. The locking member 325 is used to abut against the bottom of the body 1 so that the first limiting member 21 is spaced a preset distance from the body 1. The present disclosure does not limit the material of the locking member 325. In one embodiment, the locking member 325 is made of rubber. In the process of the lifting device 3 driving the oil cup 2 to move upward, the locking member 325 contacts the bottom of the body 1 and is compressed to produce a certain deformation. The second connecting rod 323 rises to the extreme position. At this time, the first opening at the bottom of the body 1 for the second connecting rod 323 to pass through is closed by the locking member 325. Figure 2 A schematic diagram of the range hood according to the embodiment of the present disclosure when the oil cup is not lowered is shown, there is a very small gap between the first limiting component 21 and the body 1, and the oil cup 2 is fixed in the current position. The thickness of the locking member 325 is greater than the thickness of the edge of the first limiting component 21, avoiding contact between the first limiting component 21 and the body 1, reducing wear caused by friction, and extending the service life of the first limiting component 21.

[0042] like Figure 4 The limiting assembly also includes a screw 326. A threaded hole matching the screw 326 is provided at the bottom of the second connecting rod 323. A second opening is provided on the second limiting component 324. A third opening is provided on the locking member 325. The screw 326 passes through the second opening, the third opening and the threaded hole in sequence to form a connection relationship with the second connecting rod 323. The second limiting component 324 is fixed at the bottom of the second connecting rod 323.

[0043] Figure 3 A schematic diagram is shown of the range hood lowering the oil cup according to an embodiment of the present disclosure. When the range hood lowers the oil cup 2, the user can lift the oil cup 2 upwards, thereby easily removing the oil cup 2 from the second limiting component 324. After pouring out the oil, align the first limiting component 21 of the empty oil cup with the second limiting component 324 to ensure that the oil cup 2 is firmly fixed.

[0044] Figure 6 A schematic structural diagram of a lifting device according to an embodiment of the present disclosure is shown. Figure 7 Schematic diagram showing the connection state of the screw sleeve and the screw rod according to an embodiment of the present disclosure. Figure 6 , Figure 7As shown, the linear drive module includes a drive device 311, a screw 312 driven by the drive device 311 to rotate around its own axis, a screw sleeve 313 and a push rod 314, the screw sleeve 313 is threadedly connected to the screw 312, the upper end of the push rod 314 is fixedly connected to the screw sleeve 313, and the lower end of the push rod 314 is fixedly connected to the middle of the first connecting rod 322. The threaded connection between the screw sleeve 313 and the screw 312 enables the screw sleeve 313 to move up and down along the screw 312 under the rotation drive of the screw 312, the push rod 314 moves up and down with the screw sleeve 313, and correspondingly drives the first connecting rod 322 to move up and down, the lower end of the push rod 314 is fixedly connected to the middle of the first connecting rod 322, and in the process of driving the oil cup 2 to move, it is ensured that the oil cup 2 maintains a balanced state. The linear drive module also includes a shell 315, and the inner wall of the shell 315 is provided with a longitudinal protrusion, Figure 8 A cross-sectional view showing the connection between the screw sleeve and the housing according to an embodiment of the present disclosure is shown. Figure 8 The outer wall of the screw sleeve 313 is provided with a longitudinal groove matching the longitudinal protrusion, which is used to limit the screw sleeve 313 to move up and down along the longitudinal protrusion. The cooperation between the longitudinal groove and the longitudinal protrusion ensures that the screw sleeve 313 can only move up and down, preventing any lateral or oblique movement, thereby preventing the oil cup 2 from accidentally shifting or tilting during the movement.

[0045] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
