Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of oil fume suction guide plates, specifically a kind of oil fume exhaustor with opening and closing function of smoke suction port. BACKGROUND

[0002] In modern family life, as an indispensable electrical equipment in the kitchen, the oil fume exhaustor is widely used to remove the oil fume, steam and odor generated during cooking to maintain the cleanliness and comfort of indoor air. According to the different positions and structures of the smoke suction port, the oil fume exhaustor is mainly divided into two types: top suction type and side suction type. Among them, the side suction type oil fume exhaustor gradually becomes the first choice of consumers due to its characteristics of close proximity to the pot, low installation height and high smoke suction efficiency.

[0003] In the existing design of the oil fume exhaustor, the movable panel is usually used as a shielding component of the smoke suction port to control the suction of oil fume, prevent foreign matter from entering and beautify the appearance. The traditional movable panel adopts an outwardly flipping opening mode, i.e. the panel is flipped outward and unfolded around the smoke suction port through a hinge or similar mechanism. However, this design has the following significant disadvantages in actual use:

[0004] 1. Invasion of cooking space: the outwardly flipping movable panel extends into the kitchen space in the open state, invading the user's cooking area. Especially in the case of small kitchen area, the user needs to deliberately avoid the movable panel when operating the pot or moving the body. This avoiding behavior not only increases the inconvenience of the cooking process, but also may interfere with the user's operation rhythm, significantly reducing the comfort of the cooking experience.

[0005] 2. Feeling of oppression: for the side suction type oil fume exhaustor, the smoke suction port is usually located close to the position above the pot. 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 visually easily causes a sense of oppression, especially during long-term cooking, the user may feel oppressed and uncomfortable due to the protrusion of the panel, affecting the use experience.

[0006] 3. Safety hazard: after the movable panel is flipped outward, its protruding part may collide with the user's head, hands or other kitchen objects, causing certain safety risks. Especially during the cooking peak period, the personnel in the kitchen move frequently and the space is crowded, this design may cause accidental injury or operation error, further reducing the safety of use, therefore it is necessary to make further improvement.

[0035] The track groove 5 comprises a lifting groove 51 in the shape of a long waist. A plurality of settling grooves 52 are formed in the bottom side wall of the lifting groove 51 and are in communication with the lifting groove 51.

[0036] The settling grooves 52 are provided with two first guide columns 61 and two second guide columns 62, which are slid into the settling grooves 52 to open and close the movable panel 3.

[0037] The power device 7 is provided with two sets of power devices, which are symmetrically installed in the host computer 1.

[0038] The power device 7 comprises a sliding rail 71 arranged on the host computer 1, and a connecting plate 72 is slidably installed in the sliding rail 71.

[0039] The power device 7 further comprises a first lower connecting rod 73, a second lower connecting rod 74, and an upper connecting rod 75. The connecting plate 72 is hingedly connected 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 an electric mechanism through the upper connecting rod 75. The electric mechanism drives the connecting plate 72 to slide along the sliding rail 71, thereby indirectly driving the sliding plate 6 to slide along the track groove 5.

[0040] The electric mechanism is a reduction motor 9. An output shaft 91 of the reduction motor 9 is connected to a driving arm 8, and the driving arm 8 is hingedly connected to the upper connecting rod 75.

[0041] The electric mechanism is an electric push rod. An output shaft of the electric push rod is connected to the connecting plate 72.

[0042] The output shaft 91 of the reduction motor 9 is connected to a synchronous shaft 92, which is horizontally installed in the host computer 1. The synchronous shaft 92 is connected to the driving arm 8 at both ends. The synchronous shaft 92 drives the two sets of power devices 7 to move synchronously.

[0043] The host 1 is connected with the bottom plate 10 and the protection plate 12 on both sides, and the driving mechanism is installed between the bottom plate 10 and the protection plate 12.

[0044] Working principle: the front end of the host is covered with a fixed panel, and a smoke suction port is formed below the fixed panel. The movable panel is installed at the outer end of the smoke suction port.

[0045] The driving mechanism is fixedly connected to the back of the movable panel and realizes the opening and closing function of the smoke suction port under the driving of the driving mechanism.

[0046] Firstly, the driving mechanism includes a track seat arranged on both sides of the host. A long waist-shaped lifting groove is arranged in the track seat, and a plurality of settlement grooves are formed on the bottom side wall of the lifting groove and downwardly inclined. The lifting groove and the settlement groove are in communication with each other.

[0047] 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 gradually moved upward along the settlement groove, separated from the locking of the settlement groove, and enter the lifting groove. In this process, the movable panel is pushed out and away from the smoke suction port, and the movable panel moves outward. After the second guide column and the second guide column enter the lifting groove, the power device continues to drive the sliding plate to move upward along the lifting groove. In this process, the movable panel vertically rises and translates, and at this time the smoke suction port is opened and the range hood starts to work.

[0048] When the range hood needs to close the smoke suction port, the power device reversely drives the sliding plate, and the sliding plate is locked in the original lifting groove and gradually slides downward along the lifting groove. In this process, the movable panel vertically descends and translates, and at this time the smoke suction port starts to close, and the movable panel gradually covers the outer end of the smoke suction port. When the sliding plate descends to the bottom of the lifting groove, the first guide column and the second guide column slide into the settlement groove. Due to the downward inclined design of the settlement groove, the guide column enters the deep part of the settlement groove under the action of the gravity of the movable panel or the driving force of the power device, and at this time the sliding plate is locked at the lowest position of the settlement groove, and at this time the movable panel is retracted inwardly and returns to the original position, and the movable panel tightly closes the smoke suction port.

[0049] Through the cooperation of the settling tank and the lifting tank, the "pushing out and then moving up to open, and moving down to shrink and close" mode of the movable panel makes the movable panel not occupy the space outside the kitchen during the opening process, and the user can operate freely without avoiding, avoiding the safety hazard caused by the outward movable panel. In the state of opening of the movable panel, the sliding plate can be controlled to stay at a specific position through the track groove, ensuring that the movable panel can be stably connected, and in the closed state of the movable panel, the movable panel can be locked at the bottom of the settling tank, ensuring the sealing performance of the movable panel in the closed state, and the movable panel after closing is consistent with the fixed panel.

[0050] Further, the "pushing out and then moving up to open, and moving down to shrink and close" mode of the movable panel reduces the installation precision requirement, and a large installation gap is not required between the movable panel and the fixed panel, avoiding the problems of oil fume leakage due to too large gap or collision due to too small gap.

[0051] In the installation distribution of the power device, one set can be provided, and the opening power provided by the one set of power device is enough to meet the use of most oil smoke machines on the market; or two sets can be provided, which are symmetrically installed in the main machine and connected with each other through a synchronous shaft, to ensure synchronous movement of the driving mechanism, and the two sets of symmetrically distributed power devices meet the use of high-power oil smoke machines, avoiding the problems of inclined rising or stuck pause caused by single-sided driving, especially suitable for the case of large panel, and high applicability.

[0052] The above-mentioned power device can include a slide rail fixed on the main machine, a connecting plate slidably installed in the slide rail, and the connecting plate is hingedly connected with the sliding plate through a first lower connecting rod and a second lower connecting rod; and an upper connecting rod is connected with the connecting plate and an electric mechanism, respectively. When the electric mechanism is started, a driving force is generated to drive the connecting plate to slide along the slide rail, and the sliding plate slides along the track groove, so as to realize the opening and closing of the movable panel.

[0053] The electric mechanism can be a reduction motor, and a driving arm connected with the output shaft of the reduction motor is hingedly connected with the upper connecting rod. The reduction motor provides stable driving force and accurate action with low noise, and is suitable for scenes requiring smooth opening and closing. The electric mechanism can be an electric push rod, and the output shaft of the electric push rod is connected with the connecting plate. The electric push rod has simple structure and large thrust, and is suitable for designs requiring large driving force, thereby improving the stability and reliability of the driving mechanism.

[0054] In conclusion, the oil fume machine realizes the opening and closing of the smoke suction port, the movable panel is in the movement track of "pushing outwards and then translating upwards", not only overcomes the problems of space occupation, depression and safety hazards in the traditional design, but also provides a stable and reliable operation experience through the innovative driving mechanism.
