Description

Technical Field

[0001] The present invention relates to an oil fume guiding plate, specifically an oil fume extractor with an opening and closing function at the smoke suction port. Background Art

[0002] In modern family life, the oil fume extractor, as an indispensable electrical appliance in the kitchen, is widely used to remove oil fumes, steam and odors generated during cooking to keep the indoor air clean and comfortable. According to the position and structure of the smoke suction port, the oil fume extractors are mainly divided into two types: top suction type and side suction type. Among them, the side suction type oil fume extractor has gradually become the first choice of consumers due to its characteristics such as the smoke suction port being close to the cookware, the installation height being relatively low, and the high smoke suction efficiency.

[0003] In the existing design of oil fume extractors, the movable panel usually serves as a shielding component for the smoke suction port, playing the roles of controlling the inhalation of oil fumes, preventing foreign objects from entering, and beautifying the appearance. The traditional movable panel mostly adopts an outward opening method, that is, the panel is flipped outward around the smoke suction port through a hinge or a similar mechanism. However, this design exposes the following several significant disadvantages in actual use: 1. Occupying cooking space: When the outward-opening movable panel is in the open state, it will extend into the kitchen space, occupying the user's cooking area. Especially in the case of a small kitchen area, when the user operates the cookware or moves the body, they need to deliberately avoid the movable panel. This avoidance behavior not only increases the inconvenience during the cooking process but also may interfere with the user's operation rhythm, significantly reducing the comfort of the cooking experience.

[0004] 2. Generating a sense of depression: For the side suction type oil fume extractor, its smoke suction port is usually located at a relatively close position above the cookware. When the movable panel is flipped outward, the panel is often within the user's line of sight and may even partially block the line of sight. This design is likely to cause a sense of oppression visually. Especially during long-term cooking, the user may feel depressed and uncomfortable due to the protrusion of the panel, affecting the usage experience.

[0005] 3. Existing safety hazards: After the movable panel is flipped outward, its protruding part may collide with the user's head, hand or other kitchen objects, bringing certain safety risks. Especially during the peak cooking period, when there is frequent personnel movement and crowded space in the kitchen, this design may lead to accidental bruises or operation mistakes, further reducing the safety of use. Therefore, it is necessary to make further improvements to it. Summary of the Invention

[0006] The purpose of the present invention is to overcome the disadvantages of the existing technology and provide an oil fume extractor with an opening and closing function at the smoke suction port, which has a simple structure, low production cost, can effectively improve the space utilization rate, high safety, a reliable and stable opening and closing process of the movable panel, and a neat and beautiful appearance.

[0007] The object of the present invention is achieved in the following way: An oil fume extractor with a smoking port opening and closing function, which includes a main body. The front end face of the main body is covered with a fixed panel. A smoking port is opened below the fixed panel. A movable panel is covered and installed outside the smoking port.

The movable panel realizes the opening and closing of the smoking port under the drive of the driving mechanism. Among them, the driving mechanism includes track seats arranged on both sides of the main body. A track groove is opened through the track seats. A sliding plate extends into the track groove through the first guide post and the second guide post on it and slides. Among them, the driving mechanism further includes a power device, which is connected to the sliding plate and drives it along the track groove.

[0008] The track groove includes a long waist-shaped lifting groove. The bottom side wall of the lifting groove is inclined downward to form a plurality of settling grooves. The lifting groove and the settling groove are communicated.

[0009] There are two settling grooves. The first guide post and the second guide post slide into the settling grooves to realize the opening and closing of the movable panel.

[0010] Two sets of power devices are provided and are symmetrically installed on the left and right in the main body.

[0011] The power device includes a slide rail arranged on the main body. A connecting plate is slidably installed in the slide rail. The power device further includes a first lower connecting rod, a second lower connecting rod and an upper connecting rod. The connecting plate is hinged to the sliding plate through the first lower connecting rod and the second lower connecting rod. The connecting plate is connected to the electric mechanism through the upper connecting rod. The electric mechanism pushes the connecting plate to slide along the slide rail, indirectly driving the sliding plate to slide along the track groove.

[0012] The electric mechanism is a reduction motor. The output shaft of the reduction motor is connected with a driving arm, and the driving arm is hinged to the upper connecting rod.

[0013] The electric mechanism is an electric push rod, and the output shaft of the electric push rod is connected to the connecting plate.

[0014] The output shaft of the reduction motor is connected with a synchronous shaft. The synchronous shaft is horizontally installed in the main body. Both ends of the synchronous shaft are respectively connected to the driving arm. The synchronous shaft drives the left and right two sets of power devices to move synchronously.

[0015] Both sides of the main body are connected with a bottom plate and a protective plate. The driving mechanism is installed between the bottom plate and the protective plate.

[0016] The beneficial effects of the present invention are: 1. The structure is simple, the manufacturing cost is low, and the market competitiveness is improved.

[0017] The "open by extrapolating and then moving up, close by moving down and then contracting inward" method of the movable panel. During the opening process of the movable panel, it does not occupy the external space of the kitchen, ensuring high safety.

[0018] In the open state of the movable panel, the sliding plate can be controlled to stay at a specific position through the track groove, ensuring the stable connection of the movable panel. In the closed state of the movable panel, the movable panel can be locked at the bottom of the settling groove, ensuring the sealing performance of the movable panel in the closed state. At the same time, the closed movable panel is coordinated with the fixed panel.

[0019] Reduce the requirements for installation accuracy. There is no need to reserve a large installation gap between the movable panel and the fixed panel, avoiding problems such as oil fume leakage due to too large a gap or collision during opening due to too small a gap, and improving the external beauty of the range hood.

[0028] The following further specifically describes the present invention with reference to the drawings. A range hood with a smoking port having an opening and closing function includes a main body 1. The front end face of the main body 1 is covered with a fixed panel 2. A smoking port 11 is opened below the fixed panel 2. A movable panel 3 is covered and installed outside the smoking port 11. A driving mechanism is installed on the main body 1. The back of the movable panel 3 is fixedly connected to the driving mechanism. The movable panel 3 realizes the opening and closing of the smoking port 11 under the drive of the driving mechanism. Among them, the driving mechanism includes track seats 4 arranged on both sides of the main machine 1. A track groove 5 is formed through the track seat 4. The sliding plate 6 extends into the track groove 5 through the first guiding column 61 and the second guiding column 62 thereon and slides therein. Among them, the driving mechanism further includes a power device 7. The power device 7 is connected to the sliding plate 6 and drives it along the track groove 5.

[0029] The track groove 5 includes a waist-shaped lifting groove 51. The bottom side wall of the lifting groove 51 is inclined downward to form a plurality of settling grooves 52. The lifting groove 51 and the settling grooves 52 are communicated.

[0030] There are two settling grooves 52. The first guiding column 61 and the second guiding column 62 slide into the settling grooves 52 to realize the opening and closing of the movable panel 3.

[0031] There are two sets of the power devices 7, which are symmetrically installed on the left and right in the main machine 1.

[0032] The power device 7 includes a slide rail 71 arranged on the main machine 1. A connecting plate 72 is slidably installed in the slide rail 71. The power device 7 further includes a first lower connecting rod 73, a second lower connecting rod 74 and an upper connecting rod 75. The connecting plate 72 is hinged to the sliding plate 6 through the first lower connecting rod 73 and the second lower connecting rod 74. The connecting plate 72 is connected to the electric mechanism through the upper connecting rod 75. The electric mechanism pushes the connecting plate 72 to slide along the slide rail 71, indirectly driving the sliding plate 6 to slide along the track groove 5.

[0033] The electric mechanism is a reduction motor 9. The output shaft 91 of the reduction motor 9 is connected with a driving arm 8. The driving arm 8 is hinged to the upper connecting rod 75.

[0034] The electric mechanism is an electric push rod. The output shaft of the electric push rod is connected to the connecting plate 72.

[0035] The output shaft 91 of the reduction motor 9 is connected with a synchronous shaft 92. The synchronous shaft 92 is horizontally installed in the main machine 1. The two ends of the synchronous shaft 92 are respectively connected with the driving arms 8. The synchronous shaft 92 drives the two sets of power devices 7 on the left and right to move synchronously.

[0036] Both sides of the main machine 1 are connected with a bottom plate 10 and a protection plate 12. The driving mechanism is installed between the bottom plate 10 and the protection plate 12.

[0037] Working principle: A fixed panel covers the front end face of the main machine. A smoking port is formed below the fixed panel. The movable panel is covered and installed at the outer end of the smoking port.

[0038] A driving mechanism is installed in the main unit, which is fixedly connected to the back of the movable panel and realizes the opening and closing function of the smoking port under the drive of the driving mechanism.

[0039] First, the driving mechanism includes track seats arranged on both sides of the main machine. A long waist-shaped lifting groove is arranged through the track seat, and a plurality of sedimentation grooves are formed on the bottom side wall of the lifting groove, and the lifting grooves are connected to each other.

[0040] When the range hood needs to work, the power device drives the sliding plate, and the first guide column and the second guide column of the sliding plate are originally stuck in the sedimentation tank, gradually move up along the sedimentation tank, break away from the lock of the sedimentation tank, and enter the lifting tank. In this process, the movable panel is pushed outward, away from the suction port, and performs an outward push movement. After the second guide column and the second guide column enter the lifting tank, the power device continues to drive, driving the sliding plate to move upward along the lifting tank. In this process, the movable panel rises vertically and moves horizontally, at this time the suction port is opened, and the range hood starts to work.

[0041] When the range hood needs to close the smoke outlet, the power device drives the sliding plate in the reverse direction, causing the sliding plate to be locked in the original lifting slot and gradually slide down along the lifting slot. During this process, the movable panel vertically descends and translates, and the smoke outlet begins to close, and the movable panel gradually covers the outer end of the smoke outlet. When the sliding plate descends to the bottom of the lifting slot, the first guide column and the second guide column slide into the sedimentation tank. Due to the downward tilting design of the sedimentation tank, the guide column enters the depth of the sedimentation tank under the action of the movable panel's own gravity or the driving force of the power device. At this time, the sliding plate is locked in the lowest position of the sedimentation tank, and the movable panel retracts inward to return to its original position, and the movable panel tightly closes the smoke outlet.

[0042] Through the cooperation between the settling tank and the lifting tank, the movable panel can be pushed outward and then moved upward to open, and moved downward and then retracted to close, so that the movable panel will not occupy the external space of the kitchen during the opening process, and the user can operate it freely without avoiding it, avoiding the safety hazards brought to the user by the protruding movable panel. When the movable panel is open, the sliding plate can be controlled to stay in a specific position through the track groove, ensuring that the movable panel can be stably connected. When the movable panel is closed, the movable panel can be locked at the bottom of the settling tank, ensuring the sealing of the movable panel when it is closed. At the same time, the closed movable panel is coordinated with the fixed panel.

[0043] Furthermore, the movable panel's "push outward and move upward to open, move downward and retract inward to close" method reduces the installation accuracy requirements. There is no need to reserve a large installation gap between the movable panel and the fixed panel, avoiding problems such as oil smoke leakage due to a large gap or collision due to a small gap when opened.

[0044] In the installation distribution of the power device, it can be set as a single set. The opening power provided by a single set of power devices is sufficient to meet the use of most range hoods on the market. It can also be set as two sets, symmetrically installed on the left and right inside the main unit, and the two sets of power devices are connected to each other through a synchronous shaft to ensure the synchronous movement of the drive mechanism. The two symmetrically distributed power devices meet the use of high-power range hoods, avoiding problems such as tilting upward or jamming and pausing that may be caused by single-sided driving, especially suitable for the case of a larger panel, with strong applicability.

[0045] The above-mentioned power device may include a slide rail fixed to the main unit. A connecting plate is slidably installed inside the slide rail and is hinged to a sliding plate through a first lower connecting rod and a second lower connecting rod. The upper connecting rod is respectively connected to the connecting plate and the electric mechanism. When the electric mechanism is started, it brings a driving force to push the connecting plate to slide along the slide rail, driving the sliding plate to slide along the track groove, thereby realizing the opening and closing of the movable panel.

[0046] The electric mechanism can be set as a reduction motor. The driving arm connected to the output shaft of the reduction motor is hinged to the upper connecting rod. The reduction motor provides a stable driving force, and the action is precise and the noise is low, which is suitable for use in scenarios that require smooth opening and closing. The electric mechanism can be set as an electric push rod. The output shaft of the electric push rod is connected to the connecting plate. The electric push rod has a simple structure and a large thrust, which is suitable for designs that require a large driving force, improving the stability and reliability of the drive mechanism.

[0047] In summary, the range hood of the present invention realizes the opening and closing of the smoke suction port. Under the movement track of "pushing outwards first and then translating upwards" of the movable panel, it not only overcomes problems such as occupying space, a sense of depression and potential safety hazards in traditional designs, but also provides a smooth and reliable operation experience through an innovative drive mechanism. This technical solution provides a new solution for the function optimization of range hoods and the satisfaction of user needs, so it can be widely promoted and used.
