Description
Technical Field
[0001] This utility model relates to a side-suction range hood, and in particular to a side panel flipping structure for a range hood and the range hood itself. Background Technology
[0002] The suction inlet of a side-suction range hood is located on the side of the range hood casing. Some side-suction range hoods have a movable side panel that can be flipped open and closed to cover the suction inlet. When the range hood is not working, the side panel flips open to cover the suction inlet, keeping the outward-facing side of the range hood aesthetically pleasing and flat. When the range hood is working, the side panel flips open to expose the suction inlet.
[0003] Existing range hood side panel flip structure, such as Figure 1 As shown, an electric telescopic rod 4 powered by a motor 3 is installed inside the range hood housing 1. The side panel 2 is movably connected to the range hood housing 1 via a mounting base 9 fixed inside the housing and a movable flap 5. The flap 5 is hinged to the mounting base 9 in the middle, one end of the flap is fixed to the side panel 2, and the other end is hinged to the electric telescopic rod 4. The motor 3 is also hinged to the range hood housing. When the motor operates, it extends the electric telescopic rod, which drives the side panel 2 to flip and open automatically, opening the smoke inlet. When the motor operates, it shortens the electric telescopic rod, which drives the side panel 2 to flip and close, covering the smoke inlet again. The side panel requires the motor to operate to extend and retract the electric telescopic rod, which in turn drives the flap 4 to rotate. When the motor malfunctions, the side panel cannot open automatically, rendering the range hood unusable. This requires waiting for a professional to repair the motor, causing considerable inconvenience. If the user forcibly pulls the side panel open manually, the side panel, flap 4, and electric telescopic rod will be linked, potentially damaging the motor. Furthermore, manually opening the side panel may prevent it from closing properly. Utility Model Content
[0004] To address the technical problems of existing side-suction range hoods where the side panel flipping structure cannot open automatically in case of motor failure, forcibly opening it manually will damage the motor, and the side panel may not be able to close after opening, this utility model provides a range hood side panel flipping structure that allows the side panel to be manually opened or closed even when the motor fails, without affecting or damaging the motor.
[0005] The technical solution adopted by this utility model to solve the technical problem is as follows: a side panel flipping structure for a range hood, including a side panel covering the smoke inlet and a drive mechanism with a motor. The drive mechanism drives the side panel to flip outward and open through a flip plate. Both the side panel and the flip plate are rotatably connected to the range hood housing. The drive mechanism is installed inside the range hood housing. The flip plate is characterized by being composed of a first rotating component and a second rotating component with a split structure. Both rotating components are rotatably connected to the range hood housing. The first rotating component and the second rotating component abut against each other and can rotate in the same direction. The drive mechanism is connected to the first rotating component and can drive it to rotate. The side panel is connected to the second rotating component and the two can drive each other to rotate in the same direction.
[0006] This invention replaces the original integrated flap with two separate rotating components, allowing the side panel to be opened independently by manual operation without linkage to the drive mechanism. Manually opening or closing the side panel does not affect the drive mechanism and will not damage the drive motor. Because the two rotating components are separate and rotate in the same direction, during normal operation, the drive mechanism drives the first rotating component to rotate, which in turn pushes the second rotating component to rotate in the same direction. The side panel flips open to open the smoke inlet as the second rotating component rotates. After the side panel is fully open, the drive mechanism maintains this state, keeping the first rotating component, the second rotating component, and the side panel still. When the side panel needs to be closed, the drive mechanism drives the first rotating component to rotate in the opposite direction to return it to its original position. Simultaneously, the first rotating component pushes against the second rotating component, causing it to slowly rotate in the opposite direction. The second rotating component then flips open to close the side panel under gravity. The side panel rotates synchronously back to its original position. If the drive mechanism malfunctions and cannot work, the side panel can be manually flipped open. At this time, the second rotating component rotates with the side panel, disengages from the first rotating component, and gradually moves away. After the side panel is opened to the correct position, it can be held in place by placing an object on the stove surface. When the side panel needs to be closed, remove the object and hold the side panel so that it slowly flips open and closes under the action of gravity. The second rotating component rotates back to its original position with the side panel. Whether the side panel is open or closed, the rotation of the second rotating component will not affect the first rotating component and the drive mechanism, nor will it cause damage to the motor of the drive mechanism.
[0007] As a further improvement and supplement to the technical solution, this utility model adopts the following technical measures: the driving mechanism is an electric telescopic rod equipped with a motor, one end of the motor is hinged to the inner wall of the range hood body, and one end of the electric telescopic rod is hinged to the first rotating component; or the driving mechanism is a stepper motor, which is connected to the first rotating component to make it rotate. The driving mechanism can drive the first rotating component to rotate in various forms. When the driving mechanism uses an electric telescopic rod, the electric telescopic rod pushes and pulls the first rotating component to make it rotate through length changes and swings. The first rotating component can then push or resist the second rotating component, causing it to open the side panel or slowly close with the side panel. When the driving mechanism directly uses a stepper motor, the stepper motor drives the first rotating component to rotate, pushing or resisting the second rotating component, causing it to open the side panel or slowly close with the side panel.
[0008] The first and second rotating components are rotatably connected to the same mounting base, which is fixed to the inner wall of the range hood housing. By first rotatably connecting the two rotating components to a single mounting base, and then fixing the mounting base to the inner wall of the range hood housing, the two rotating components are no longer separately installed on the inner wall of the housing, which simplifies the manufacturing process and improves production efficiency.
[0009] The rotation axes of the first and second rotating components coincide. By aligning the rotation axes of the two rotating components, the contact between them remains stable during their contact and rotation in the same direction, preventing relative slippage and reducing frictional losses and noise caused by slippage.
[0010] The first and second rotating components are respectively provided with a first plane and a second plane of matching dimensions, and they make contact through the two planes. The first and second rotating components complete the rotation in the same direction by making contact through the matching planes. The planar structure is simple and easy to process.
[0011] The first and second rotating components are respectively provided with a first pad and a second pad on their adjacent sides, and they abut against each other through the adhesion of the two pads. The outer surfaces of the first and second pads respectively form a first plane and a second plane. The two rotating components abut against each other by attaching a pad to their adjacent sides, thereby reducing friction and noise generated by the abutment. The thickness of the two pads can be adjusted to fit the gap between the two rotating components after installation, ensuring that the two rotating components can abut against each other.
[0012] The second rotating component has a locking hole through which a stop bar can pass. When the side panel is flipped open to the correct position, the second rotating component partially extends out of the smoke inlet, positioning the locking hole outside the smoke inlet. By inserting the stop bar through the locking hole and abutting against the edge of the smoke inlet on the range hood housing, the second rotating component and the side panel are locked in place. When the side panel is manually flipped open, the second rotating component rotates synchronously with the side panel and partially extends out of the smoke inlet. At this time, by inserting the stop bar through the locking hole and using the stop bar to abut against the edge of the smoke inlet on the range hood housing, the current position of the second rotating component and the side panel can be locked, keeping the baffle in the open state and thus opening the smoke inlet.
[0013] The second objective of this invention is to provide a range hood, specifically a side-draft range hood with a suction inlet on its lower side. This side-draft range hood features a side panel flip-up structure at the suction inlet, characterized in that the side panel flip-up structure is one of the aforementioned range hood side panel flip-up structures. Using this aforementioned side panel flip-up structure, the side panel for opening and closing the suction inlet can be manually and independently opened without affecting the drive mechanism. Opening the side panel will not affect the drive mechanism, and there is no need to worry about damaging the motor of the drive mechanism.
[0014] The range hood has two side panel flipping structures, located at both ends of the smoke inlet. The side panels of both structures share a common common side panel. The range hood can have one side panel flipping structure at each end of the smoke inlet, with the side panel being a single common panel. Two drive mechanisms can synchronously drive the side panel to flip open. Even if the motor of one drive mechanism fails, the side panel can still be manually flipped open without affecting the drive mechanism or its motor.
[0015] The range hood has one flip-up side panel structure, located either in the middle or at one of the two ends of the smoke inlet. The range hood has only one flip-up side panel structure located in the middle or at one of the two ends of the smoke inlet.
[0016] The beneficial technical effects of this utility model are: the original one-piece flip plate is changed into two separate components, so that the side plate can be manually operated to flip and open independently without linkage with the drive mechanism. At the same time, the opening of the side plate will not affect the drive mechanism, nor will it cause damage to the motor of the drive mechanism. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 2-4 As shown, Embodiment 1 is a side panel flipping structure for a range hood, including a side panel 2 covering the smoke inlet 12 and a drive mechanism with a motor 3. The drive mechanism drives the side panel 2 to flip outward and open via a flip plate. Both the side panel 2 and the flip plate are rotatably connected to the range hood housing 1. The drive mechanism is installed inside the range hood housing 1. The flip plate consists of a first rotating component 6 and a second rotating component 7 with a split structure. Both rotating components are rotatably connected to the range hood housing 1. The first rotating component 6 and the second rotating component 7 abut against each other and can rotate in the same direction. The drive mechanism is connected to the first rotating component 6 and can drive it to rotate. The side panel 2 is connected to the second rotating component 7, and the two can drive each other to rotate in the same direction. In this embodiment, the drive mechanism is preferably equipped with an electric telescopic rod 4 with a motor 3. One end of the motor 3 is hinged to the inner wall of the range hood housing 1, and one end of the electric telescopic rod 4 is hinged to the first rotating component 6.
[0024] In this embodiment, the flap is designed as two rotating parts of a split structure. The side plate can be opened and closed independently by manual operation without linkage with the drive mechanism. The opening and closing of the side plate will not affect the drive mechanism, nor will it cause damage to the motor of the drive mechanism.
[0025] When the motor is functioning normally, it extends the electric telescopic rod, which in turn pushes the first rotating component to rotate. The first rotating component then pushes the second rotating component to rotate in the same direction. The side panel flips open to reveal the smoke inlet as the second rotating component rotates. Once the side panel is fully open, the electric telescopic rod maintains its current length, keeping the first rotating component, the second rotating component, and the side panel in place. Figure 3 In this state, the side panels automatically open under the operation of the electric telescopic rod, from... Figure 2 The state becomes Figure 3 The side panel is in a closed state. When the side panel is closed, the electric telescopic rod drives the first rotating component to rotate in the opposite direction to return to its original position. At the same time, the first rotating component abuts against the second rotating component, causing it to slowly rotate in the opposite direction. Under the action of gravity, the side panel flips and closes, driving the second rotating component to rotate synchronously back to its original position, and the side panel returns to its original position. Figure 2 The state.
[0026] When the motor malfunctions and cannot work, the side plate can be manually flipped open. At this time, the second rotating component rotates with the side plate, disengaging from the first rotating component and gradually moving away from it. The side plate then... Figure 2 The state becomes Figure 4 Once the side panel is fully open, it can be held in place by placing an object on the stovetop. When the side panel needs to be closed, remove the object and hold the panel in place so that it slowly rotates and closes under gravity. The second rotating component returns to its original position as the side panel rotates, and the side panel returns to its original position. Figure 2 The second rotating component will not affect the first rotating component or the electric telescopic rod, regardless of whether the side panel is manually flipped open or closed, nor will it damage the motor on the electric telescopic rod.
[0027] Furthermore, the drive mechanism in this embodiment can be replaced by a stepper motor instead of an electric telescopic rod. The stepper motor is connected to the first rotating member 6 to make it rotate. When the stepper motor is working properly, it drives the first rotating member to rotate, pushing or blocking the second rotating member, causing the second rotating member to automatically open the side plate or slowly close it with the side plate. If the stepper motor fails, the side plate can be opened or closed manually as in the previous embodiment.
[0028] Furthermore, the first rotating component 6 and the second rotating component 7 are rotatably connected to the same mounting base 9, which is fixed to the inner wall of the range hood housing 1. The range hood housing is mostly made of stainless steel sheet and frame. By unifying the two rotating components with a single mounting base and fixing the mounting base to the inner wall of the range hood housing, it is not necessary to separately install the two rotating components on the inner wall of the housing, which helps to simplify the manufacturing process and improve production efficiency.
[0029] The first rotating component 6 and the second rotating component 7 are rotatably connected to the mounting base 9, and their axes of rotation coincide. Simultaneously, the first rotating component 6 and the second rotating component 7 each have a first plane and a second plane of matching dimensions, and they abut against each other through these two planes. By aligning the axes of rotation of the two rotating components, the contact between them remains stable during their abutment and rotation in the same direction, preventing relative slippage and reducing frictional losses and noise caused by slippage. The first rotating component and the second rotating component achieve rotation in the same direction through abutment contact via matching planes; the planar structure is simple and easy to manufacture.
[0030] The first rotating member 6 and the second rotating member 7 are also provided with a first pad 10 and a second pad 11 on their adjacent sides, respectively, and are abutted against each other by the two pads. The outer surfaces of the first pad 10 and the second pad 11 form a first plane and a second plane, respectively. The two rotating members each have a pad attached to their adjacent sides for contact, realizing the abutment between the two rotating members and reducing the friction and noise generated by the abutment. The two pads can also be further adjusted in thickness to fit the installation gap between the two rotating members, ensuring the abutment between the two rotating members.
[0031] The second rotating part 7 has a locking hole 8 through which the baffle rod can pass. When the side plate 2 is flipped open to the position, the second rotating part 7 extends out of the smoke inlet 12 and the locking hole 8 is on the outside of the smoke inlet 12. As long as the baffle rod passes through the locking hole 8 and abuts against the edge of the smoke inlet 12 of the range hood housing 1, the second rotating part 7 and the side plate 2 are locked. At this time, the baffle rod abuts against the edge of the smoke inlet of the range hood housing surface, locking the current position of the second rotating part and the side plate, keeping the baffle in the open state, and keeping the smoke inlet open.
[0032] Example 2 is a range hood, see reference. Figures 2-4 As shown, the range hood is a side-draft range hood with a smoke inlet 12 on its lower side. The side-draft range hood has a side panel flipping structure at the smoke inlet 12, which is the same side panel flipping structure described in Example 1. The range hood side panel flipping structure can be one or two locations. In the case of two locations, the two side panel flipping structures are located at opposite ends of the smoke inlet 12, and the side panels 2 of the two flipping structures share a common side panel. In the case of one location, it is located in the middle of the smoke inlet 12 or at one of the two ends of the smoke inlet 12.
[0033] The side-suction range hood uses the aforementioned side panel flipping structure. The side panel for opening and closing the smoke inlet can be manually operated independently without being linked to the drive mechanism. The opening and closing of the side panel will not affect the drive mechanism, and there is no need to worry about damaging the motor of the drive mechanism.
