Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a range hood door panel assembly mounting structure and a range hood having the door panel assembly mounting structure. Background Technology

[0002] Range hoods are primarily used to extract cooking fumes in the kitchen, preventing them from polluting the kitchen. A typical range hood consists of a housing and a door assembly. The housing has a smoke collection chamber inside, and a smoke inlet connected to the chamber is located at the bottom of the housing. The door assembly is rotatably mounted to the smoke inlet via a door assembly mounting structure, allowing it to open or close. In existing technology, a rotating component is located on each of the left and right sides of the door assembly. External force acts on one of these rotating components to control the opening or closing of the smoke inlet. The side of the door assembly with the rotating component subjected to external force is the active end, and the other side is the driven end. However, with this door assembly mounting structure, when closing the smoke inlet, the external force only acts on the active end, resulting in insufficient self-locking force on the driven end. This prevents the driven end of the door assembly from fully closing the smoke inlet, thus affecting the aesthetics of the range hood. Summary of the Invention

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an installation structure for a range hood door panel assembly, which can achieve pre-locking of the driven end, thus solving the problem that the driven end of the door panel assembly cannot completely close the smoke inlet when the smoke inlet is closed.

[0004] This utility model also proposes a range hood having the above-mentioned range hood door panel assembly installation structure.

[0005] A range hood door panel assembly mounting structure according to a first aspect of the present invention includes a door panel assembly, an active rotating assembly, and a driven rotating assembly. The door panel assembly has an active end and a driven end. The active rotating assembly is located at the active end of the door panel assembly. A first mounting structure and a pre-tightening structure are provided between the active rotating assembly and the door panel assembly. The active rotating assembly is connected to the door panel assembly through the first mounting structure. The pre-tightening structure includes a first mounting hole, a second mounting hole, and a connector. The first mounting hole is disposed in the active rotating assembly, and the second mounting hole is disposed in the door panel assembly. The driven rotating assembly is located at the driven end of the door panel assembly. A second mounting structure is provided between the driven rotating assembly and the door panel assembly. The driven rotating assembly is connected to the door panel assembly through the second mounting structure. When both the active rotating assembly and the driven rotating assembly are connected to the door panel assembly, the first mounting hole is offset relative to the second mounting hole in a direction away from the door panel assembly. The connector passes through the first mounting hole and the second mounting hole so that the driven end of the door panel assembly swings toward the driven rotating assembly.

[0006] According to an embodiment of the present utility model, the installation structure of a range hood door panel assembly has at least the following beneficial effects:

[0007] The range hood door panel assembly installation structure of this utility model embodiment includes a pre-tightening structure between the active rotating assembly and the door panel assembly. This pre-tightening structure allows the active rotating assembly and the door panel assembly to move closer together under elastic deformation. After connection, a rebound force is generated between the active rotating assembly and the door panel assembly, pushing the active end of the door panel assembly away from the active rotating assembly. Correspondingly, a pressure is generated between the driven rotating assembly and the door panel assembly, pushing the driven end of the door panel assembly towards the driven rotating assembly. When closing the smoke inlet, the driven end of the door panel assembly, under pressure, can first adhere to the housing, followed by the active end. This solves the technical problem of traditional door panel assembly installation structures where the driven end of the door panel assembly cannot completely close the smoke inlet due to insufficient self-locking force, resulting in a more aesthetically pleasing range hood.

[0008] According to some embodiments of the present invention, the first mounting structure includes a third mounting hole, a fourth mounting hole, and a connector. The third mounting hole is disposed in the active rotating component, and the fourth mounting hole is disposed in the door panel component. The third mounting hole and the fourth mounting hole correspond to each other. The connector passes through the third mounting hole and the fourth mounting hole to connect the active rotating component and the door panel component together. The second mounting structure includes a fifth mounting hole, a sixth mounting hole, and a connector. The fifth mounting hole is disposed in the driven rotating component, and the sixth mounting hole is disposed in the door panel component. The fifth mounting hole and the sixth mounting hole correspond to each other. The connector passes through the fifth mounting hole and the sixth mounting hole to connect the driven rotating component and the door panel component together.

[0009] According to some embodiments of the present invention, a driving device is also included, which is connected to the active rotating component and is capable of driving the active rotating component to swing in the back-and-forth direction.

[0010] According to some embodiments of the present invention, the driving device includes a motor and a transmission assembly. The transmission assembly includes a lead screw and a lead screw sleeve. The output end of the motor is connected to the lead screw sleeve in a transmission connection. The lead screw sleeve is threaded to the outer periphery of the lead screw. The motor can drive the lead screw sleeve to rotate in the forward or reverse direction. The lead screw moves back and forth along the axial direction and drives the active rotation assembly to drive the door panel assembly to swing in the back and forth direction.

[0011] According to some embodiments of this utility model, the lead screw sleeve is a worm gear, and the output end of the motor is connected to a worm, which meshes with the worm gear.

[0012] According to some embodiments of the present invention, the active rotation assembly includes a first rotating bracket, a first fixed plate, and a connecting rod. The first rotating bracket is connected to the door panel assembly. The first rotating bracket has a first rotating hole, and the first fixed plate has a second rotating hole. The first rotating hole and the second rotating hole correspond to each other. A connecting member passes through the first rotating hole and the second rotating hole, allowing the first rotating bracket to be rotatably connected to the first fixed plate. The first rotating bracket has a third rotating hole, and the connecting rod has a fourth rotating hole. The third rotating hole and the fourth rotating hole correspond to each other. A connecting member passes through the third rotating hole and the fourth rotating hole, allowing the first rotating bracket to be rotatably connected to the connecting rod. The connecting rod has a fifth rotating hole, and the lead screw has a sixth rotating hole. The fifth rotating hole and the sixth rotating hole correspond to each other. A connecting member passes through the fifth rotating hole and the sixth rotating hole, allowing the connecting rod to be rotatably connected to the lead screw.

[0013] According to some embodiments of the present invention, the distance from the first rotating hole to the third rotating hole is less than the distance from the fourth rotating hole to the fifth rotating hole.

[0014] According to some embodiments of the present invention, the first fixing plate has a limiting flange, which can abut against the first rotating bracket and restrict the first rotating bracket from swinging forward.

[0015] According to some embodiments of the present invention, the active rotation assembly further includes an elastic element, which is disposed between the first rotating bracket and the first fixed plate, or between the first rotating bracket and the connecting rod.

[0016] According to a second aspect of the present invention, a range hood includes a range hood body, wherein the range hood body is configured with the above-mentioned range hood door panel assembly mounting structure.

[0017] A range hood according to an embodiment of the present utility model has at least the following beneficial effects:

[0018] This embodiment of the range hood employs the aforementioned door panel assembly installation structure. A pre-tightening structure is provided between the active rotating assembly and the door panel assembly. This pre-tightening structure allows the active rotating assembly and the door panel assembly to move closer together under elastic deformation. After connection, a rebound force is generated between the active rotating assembly and the door panel assembly, pushing the active end of the door panel assembly to move away from the active rotating assembly. Correspondingly, a pressure is generated between the driven rotating assembly and the door panel assembly, pushing the driven end of the door panel assembly to move closer to the driven rotating assembly. When closing the smoke inlet, the driven end of the door panel assembly, under pressure, can first adhere to the housing, followed by the active end. This solves the technical problem of traditional door panel assembly installation structures where the driven end cannot completely close the smoke inlet due to insufficient self-locking force, resulting in a more aesthetically pleasing range hood.

[0035] Reference Figures 1 to 4 According to a first aspect embodiment of the present invention, a range hood door panel assembly mounting structure includes a door panel assembly 100, an active rotating assembly 200, and a driven rotating assembly 300. The door panel assembly 100 has an active end and a driven end. The active rotating assembly 200 is located at the active end of the door panel assembly 100. A first mounting structure 230 and a pre-tightening structure 240 are provided between the active rotating assembly 200 and the door panel assembly 100. The active rotating assembly 200 is connected to the door panel assembly 100 through the first mounting structure 230. The pre-tightening structure 240 includes a first mounting hole 241, a second mounting hole 242, and a connector. The first mounting hole 241 is disposed in the active rotating assembly 200. 00, the second mounting hole 242 is provided in the door panel assembly 100; the driven rotating assembly 300 is located at the driven end of the door panel assembly 100, and a second mounting structure 330 is provided between the driven rotating assembly 300 and the door panel assembly 100, and the driven rotating assembly 300 is connected to the door panel assembly 100 through the second mounting structure 330; when the active rotating assembly 200 and the driven rotating assembly 300 are connected to the door panel assembly 100, the first mounting hole 241 is offset relative to the second mounting hole 242 in a direction away from the door panel assembly 100, and the connector passes through the first mounting hole 241 and the second mounting hole 242 so that the driven end of the door panel assembly 100 swings toward the driven rotating assembly 300.

[0036] By adopting the above structure, the pre-tightening structure 240 allows the active rotating component 200 and the door panel component 100 to approach and connect to each other under elastic deformation. After connection, a rebound force is generated between the active rotating component 200 and the door panel component 100, pushing the active end of the door panel component 100 to move away from the active rotating component 200. Correspondingly, a pressure is generated between the driven rotating component 300 and the door panel component 100, pushing the driven end of the door panel component 100 to move towards the driven rotating component 300. When closing the smoke inlet, the driven end of the door panel component 100 can first adhere to the housing under pressure, and the active end adheres to the housing later. This solves the technical problem of the traditional door panel component installation structure where the driven end of the door panel component 100 cannot completely close the smoke inlet due to insufficient self-locking force, resulting in a better aesthetic appearance of the range hood.

[0037] It should be noted that when both the active rotating component 200 and the driven rotating component 300 are connected to the door panel assembly 100, the first mounting hole 241 is misaligned relative to the second mounting hole 242 in a direction away from the door panel assembly 100. At this time, the connector cannot simultaneously pass through the first mounting hole 241 and the second mounting hole 242. Pressure needs to be applied to the door panel assembly 100 to cause it to elastically deform in a direction closer to the active rotating component 200, thereby aligning the first mounting hole 241 with the second mounting hole 242, allowing the connector to pass through both holes. When the pressure is removed, the door panel assembly 100 has a rebound force to return to its original shape. The connector passing through the first mounting hole 241 and the second mounting hole 242 prevents the door panel assembly 100 from returning to its original shape. At this time, the rebound force of the door panel assembly 100 continues to act and pushes the active end of the door panel assembly 100 to move in a direction away from the active rotating component 200. When the driven end of the door panel assembly 100 is subjected to pressure, since the door panel assembly 100 is connected to the driven rotating assembly 300 through the second mounting structure 330, the driven end of the door panel assembly 100 cannot undergo elastic deformation along the direction close to the driven rotating assembly 300. At this time, after the external pressure is removed, the rebound force from the driving end becomes the pressure that pushes the driven end of the door panel assembly 100 to move along the direction close to the driven rotating assembly 300.

[0038] It is understood that the connectors are usually bolts, screws, connecting pins or other connectors that can be inserted into the mounting holes, and this utility model does not specifically limit them.

[0039] Reference Figures 1 to 3In some embodiments of this utility model, the first mounting structure 230 includes a third mounting hole 231, a fourth mounting hole 232, and a connector. The third mounting hole 231 is disposed in the active rotating component 200, and the fourth mounting hole 232 is disposed in the door panel component 100. The third mounting hole 231 and the fourth mounting hole 232 correspond to each other. The connector passes through the third mounting hole 231 and the fourth mounting hole 232 to connect the active rotating component 200 and the door panel component 100 together. The second mounting structure 330 includes a fifth mounting hole 331, a sixth mounting hole 332, and a connector. The fifth mounting hole 331 is disposed in the driven rotating component 300, and the sixth mounting hole 332 is disposed in the door panel component 100. The fifth mounting hole 331 and the sixth mounting hole 332 correspond to each other. The connector passes through the fifth mounting hole 331 and the sixth mounting hole 332 to connect the driven rotating component 300 and the door panel component 100 together.

[0040] Reference Figures 1 to 7 In some embodiments of this utility model, a driving device 400 is also included. The driving device 400 is connected to the active rotating component 200 and can drive the active rotating component 200 to swing in the back-and-forth direction.

[0041] By adopting the above structure, the drive device 400 can drive the active rotation component 200 to swing in the front and back direction, and the active rotation component 200 drives the door panel component 100 to swing in the front and back direction, so that there is no need to manually open or close the door panel component 100, which is convenient for daily use.

[0042] It is understood that the driving form of the driving device 400 can be electric motor driven, hydraulic drive, pneumatic drive, magnetic drive or other driving forms, and this utility model does not make specific limitations in this regard.

[0043] Reference Figures 1 to 7 In some embodiments of this utility model, the driving device 400 includes a motor 410 and a transmission assembly 420. The transmission assembly 420 includes a lead screw and a lead screw sleeve. The lead screw has an external thread, and the lead screw sleeve has an internal thread. The output end of the motor 410 is connected to the lead screw sleeve in a transmission connection. The lead screw sleeve is threaded to the outer circumference of the lead screw. The motor 410 can drive the lead screw sleeve to rotate in the forward or reverse direction. The lead screw moves back and forth along the axial direction and drives the active rotation assembly 200 to drive the door panel assembly 100 to swing in the back and forth direction.

[0044] By adopting the above structure, the rotational force output by the motor 410 can be converted into the force of the lead screw moving back and forth through the lead screw sleeve, thereby driving the door panel assembly 100 to swing in the back and forth direction. The motor 410 can also precisely control the opening angle of the door panel assembly 100 through the control system to meet various usage needs.

[0045] Reference Figures 1 to 7In some embodiments of this utility model, the lead screw sleeve is a worm gear, and the output end of the motor 410 is connected to a worm, which meshes with the worm gear.

[0046] By adopting the above structure, when the motor 410 outputs power through the worm gear structure, the motor 410 can be positioned perpendicular to the lead screw, thereby making the drive device 400 shorter and more compact, allowing it to be installed in a smaller housing. Simultaneously, the meshing of the worm gear and worm is smooth, reducing the likelihood of tooth breakage and jamming, effectively minimizing dead spots and thus lowering the probability of malfunctions.

[0047] Reference Figures 1 to 7 In some embodiments of this utility model, the active rotation assembly 200 includes a first rotation bracket 210, a first fixing plate 250, and a connecting rod 260. The first rotation bracket 210 is connected to the door panel assembly 100. The first rotation bracket 210 has a first rotation hole 211, and the first fixing plate 250 has a second rotation hole 251. The first rotation hole 211 and the second rotation hole 251 correspond to each other. A connecting member passes through the first rotation hole 211 and the second rotation hole 251, so that the first rotation bracket 210 and the first fixing plate 250 are rotatably connected. The first rotating bracket 210 has a third rotating hole 212, and the connecting rod 260 has a fourth rotating hole 261. The third rotating hole 212 and the fourth rotating hole 261 correspond to each other. A connecting member passes through the third rotating hole 212 and the fourth rotating hole 261 so that the first rotating bracket 210 and the connecting rod 260 are rotatably connected. The connecting rod 260 has a fifth rotating hole 262, and the lead screw has a sixth rotating hole 4211. The fifth rotating hole 262 and the sixth rotating hole 4211 correspond to each other. A connecting member passes through the fifth rotating hole 262 and the sixth rotating hole 4211 so that the connecting rod 260 and the lead screw are rotatably connected.

[0048] By adopting the above structure, the first rotating bracket 210, the first fixed plate 250 and the connecting rod 260 are a three-bar linkage mechanism. Compared with the traditional two-bar linkage mechanism, the size of the first rotating bracket 210 can be smaller, thereby making the active rotating component 200 occupy less space in the box and enabling the active rotating component 200 to adapt to narrower and thinner boxes.

[0049] Reference Figures 1 to 7 In some embodiments of this utility model, the distance from the first rotating hole 211 to the third rotating hole 212 is less than the distance from the fourth rotating hole 261 to the fifth rotating hole 262.

[0050] By adopting the above structure, the lever arm of the first rotating hole 211 to the third rotating hole 212 is smaller than that of the fourth rotating hole 261 to the fifth rotating hole 262. According to the lever arm conversion principle, the driving thrust of the drive device 400 can be converted into the flipping force of the door panel assembly 100 to a large extent, and the drive device 400 can drive the door panel assembly 100 to open or close more easily.

[0051] Reference Figures 1 to 7 In some embodiments of this utility model, the first fixing plate 250 has a limiting folded edge 252, which can abut against the first rotating bracket 210 and restrict the first rotating bracket 210 from swinging forward.

[0052] By adopting the above structure, the limiting fold 252 restricts the first rotating bracket 210 from swinging forward to control the maximum opening angle of the door panel assembly 100, and at the same time can effectively solve the problem that the door panel assembly 100 is prone to loosening when it is at the maximum opening angle.

[0053] Reference Figure 5 and Figure 6 In some embodiments of this utility model, the active rotation component 200 further includes an elastic element 270, which is an elastic washer. The elastic element 270 is sleeved on the connector and is disposed between the first rotating bracket 210 and the first fixing plate 250, or between the first rotating bracket 210 and the connecting rod 260.

[0054] By adopting the above structure, the elastic element 270 can provide additional pressure and fastening force during connection, making the connection more stable. In addition, the elastic element 270 can also reduce the wear caused by friction between the first rotating bracket 210 and the first fixed plate 250 or between the first rotating bracket 210 and the connecting rod 260 due to mutual rotation. This makes the door panel assembly installation structure have a longer service life and is safer and more reliable.

[0055] It should be noted that the elastic element 270 is usually sleeved on the connector, or the elastic element 270 can be directly set on the surface of the first rotating bracket 210, the first fixing plate 250, the first rotating bracket 210 or the connecting rod 260.

[0056] Reference Figures 1 to 7 According to a second aspect of the present invention, a range hood includes a range hood body, and the range hood body is equipped with a range hood door panel switch structure as described in the above embodiment.

[0057] The range hood of this embodiment employs the aforementioned door panel opening and closing structure. The pre-tightening structure 240 allows the active rotating component 200 and the door panel component 100 to connect close to each other under elastic deformation. After connection, a rebound force is generated between the active rotating component 200 and the door panel component 100, pushing the active end of the door panel component 100 to move away from the active rotating component 200. Correspondingly, a pressure is generated between the driven rotating component 300 and the door panel component 100, pushing the driven end of the door panel component 100 to move closer to the driven rotating component 300. When closing the smoke inlet, the driven end of the door panel component 100, under pressure, can first adhere to the housing, and the active end adheres to the housing later. This solves the technical problem of insufficient self-locking force of the driven end of the door panel component 100 in traditional door panel assembly installation structures, resulting in the inability of the driven end to fully close the smoke inlet. This also improves the aesthetics of the range hood.

[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
