Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a range hood. Background Art

[0002] During cooking, due to the heat generated by the heating in the pot, the oil smoke will spread rapidly during the rising process. If the smoke collection effect of the range hood is poor, it is easy for the oil smoke to escape, resulting in insufficient smoke extraction. To address this phenomenon, most of the main solutions are to increase the smoke collection area by using movable panels to prevent the escape of oil smoke; or to move the negative pressure area downward by raising and lowering the oil net, so that the oil smoke can be sucked out before it spreads over a large area.

[0003] In addition, the range hood with large flat glass has gradually become the first choice of market consumers due to its unique appearance and good consistency. At the same time, the panel glass will gradually block the view during the opening process. In order to avoid this problem and improve the smoke collection ability, most range hoods in the relevant technology use the form of lifting and flipping to realize the movement trajectory of the glass panel. However, there are still some problems to a certain extent. For example, the panel is only supported by the motion connecting rod, which makes the motor's motion load large. If dual motor control is used, the cost is high and the motion control is poor, which affects the life of the moving parts. Long-term use is prone to jitter, abnormal noise and other problems. Summary of the invention

[0004] The present invention aims to solve at least one of the problems existing in the existing related technologies to a certain extent. To this end, the present invention proposes a range hood with a simple structure, which can enable the panel of the range hood to achieve a compound movement of flipping and lifting, while also effectively improving the stability of the compound movement of the panel.

[0030] The following embodiments are used to illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific implementation manners of the present invention or making equivalent replacements for some technical features without departing from the spirit of the solution of the present invention shall all be covered within the scope of the technical solution claimed by the present invention.

[0031] As Figures 1 to 6 shown, this embodiment provides a range hood, including:

[0032] The main body 1 of the range hood, and the main body 1 of the range hood has an air inlet 11;

[0033] The opening and closing panel 3 is movably arranged on the main body 1 of the range hood through an opening and closing component 4;

[0034] The oil mesh component 5 is arranged on the opening and closing component 4. The oil mesh component 5 can follow the opening and closing of the opening and closing component 4 to open and close the air inlet 11;

[0035] The lifting panel 2 is slidably arranged on the opening and closing panel 3;

[0036] The driving component 6 is arranged on the main body 1 of the range hood, and the output end of the driving component 6 is connected to the lifting panel 2. One end of the opening and closing panel 3 is hinged to the main body 1 of the range hood, and the other end is linked to the opening and closing component 4. The driving component 6 drives the lifting panel 2 to move relative to the opening and closing panel 3 to drive the opening and closing component 4 to perform a flipping motion, and through the action of the opening and closing component 4 to drive the oil mesh component 5 to open or close the air inlet 11.

[0037] In this embodiment, the overall movement of the range hood is a composite movement of the opening and closing and lifting of the panel. When the driving component 6 drives the lifting panel 2 to rise relative to the opening and closing panel 3, at the same time, the lifting panel 2 drives the opening and closing panel 3 to move through the opening and closing component 4 so that the opening and closing panel 3 and the opening and closing component 4 are synchronously flipped outwards. Through the flipping motion of the opening and closing component 4, the oil mesh component 5 is driven to open the air inlet 11; when the driving component 6 drives the lifting panel 2 to descend relative to the opening and closing panel 3, at the same time, the lifting panel 2 drives the opening and closing panel 3 to move through the opening and closing component 4 so that the opening and closing panel 3 and the opening and closing component 4 are synchronously flipped inwards. Through the flipping motion of the opening and closing component 4, the oil mesh component 5 is driven to close the air inlet 11, and the oil mesh component 5 retracts and hides inside the main body 1 of the range hood. Its structure is simple, the panel of the range hood can realize the composite movement of flipping and lifting, and at the same time, the smoothness of the composite movement of the panel is effectively improved.

[0038] In this embodiment, in order to improve the aesthetic degree of the range hood, a glass panel can be arranged in front of the lifting panel 2. The glass panel is preferably made of glass, but is not limited to glass, and more suitable materials can also be selected according to the actual situation.

[0039] Furthermore, the opening and closing component 4 includes a support connecting rod 41. One end of the support connecting rod 41 is hinged to the main body 1 of the range hood, and the other end passes through the opening and closing panel 3 and is hinged to the lifting panel 2. Its structure is simple and the design is reasonable, which can realize the linkage of the composite movement of the lifting panel 2 and the opening and closing panel 3, and avoid problems such as non-synchronization or deviation of the left and right movements.

[0040] Preferably, the oil screen assembly 5 includes an oil screen 51 and an oil screen bracket 52. The opening and closing assembly 4 further includes a connecting rod 53. One end of the connecting rod 53 is hinged to the main body 1 of the range hood, and the other end is hinged to the oil screen bracket 52. The oil screen bracket 52 is hinged to the movable end of the opening and closing panel 3 at the end far from the connecting rod 53. The oil screen 51 is arranged on the oil screen bracket 52. Its structure is simple, and it can move the negative pressure area of the range hood downward to further improve the smoking effect of the range hood.

[0041] Specifically, it further includes a hinge assembly 7. The hinge assembly 7 has a first hinge 71 and a second hinge 72 hinged together through a hinge shaft. The first hinge 71 is arranged on the main body 1 of the range hood, and the second hinge 72 is arranged at the upper end of the opening and closing panel 3. Its design is reasonable, and it can further improve the stability of the flipping movement of the opening and closing panel 3.

[0042] In this embodiment, a connecting support is welded and fixed to the side of the lifting panel 2 close to the opening and closing panel 3. One end of the support connecting rod 41 passes through the opening and closing panel 3 and is hinged to the connecting support through an axially-positioned screw, and the other end is hinged and fixed to the side plate of the main body 1 of the range hood through a riveting joint. The support connecting rods 41 are symmetrically arranged on both sides of the main body 1 of the range hood. Through the support connecting rods 41, the combined movement of the lifting panel 2 and the opening and closing panel 3 is realized in a linkage manner. Its synchronization is good, and problems such as non-synchronization or skew in the left and right movements are avoided. The upper part of the opening and closing panel 3 is fixedly connected to the front end of the main body 1 of the range hood through the hinge assembly 7. The first hinge 71 and the second hinge 72 of the hinge assembly 7 are hinged together through a hinge shaft, so that the opening and closing panel 3 makes a flipping movement around the front end of the main body 1 of the range hood. It makes a synchronous opening and closing movement driven by the lifting movement of the lifting panel 2, so that the opening and closing movement of the opening and closing panel 3 and the lifting movement of the lifting panel 2 achieve a linkage effect. In this embodiment, the lower end of the opening and closing panel 3 is hinged to one end of the oil screen bracket 52, and the other end of the oil screen bracket 52 is hinged to the main body 1 of the range hood. The oil screen bracket 52, the opening and closing panel 3, and the smoke collecting hood of the main body 1 of the range hood together form a four-bar linkage mechanism. During the opening and closing process of the opening and closing panel 3, since the oil screen 51 is fixedly installed on the oil screen bracket 52, when the oil screen bracket 52 is opened synchronously with the opening and closing panel 3, the oil screen 51 extends downward, moving the negative pressure area of the range hood downward, which can further improve the smoking effect of the range hood.

[0043] Preferably, the driving assembly 6 includes a driving device 61, a screw rod, and a slider 62. A chute 31 is provided on the opening and closing panel 3. The output end of the driving device 61 is connected to the screw rod. The slider 62 is slidably arranged on the screw rod and the slider 62 moves cyclically along the screw rod. The end of the slider 62 far from the screw rod passes through the chute 31 and is fixedly connected to the lifting panel 2. Its structure is simple, and it can further improve the stability of the combined movement of the lifting panel 2 and the opening and closing panel 3.

[0044] Furthermore, the driving assembly 6 further includes an elastic element 63. An opening 21 is formed in the lifting panel 2. One end of the elastic element 63 passes through the opening 21 and is connected to the upper end of the opening and closing panel 3, and the other end is connected to the lower end of the lifting panel 2. Its structure is simple and compact, and it can effectively avoid jitter during movement due to excessive load.

[0045] In this embodiment, the driving device 61 is preferably a motor, but is not limited to a motor. A suitable driving device 61 can also be selected according to actual needs. In this embodiment, the driving device 61 is described by taking a motor as an example, and other types of driving devices 61 will not be elaborated. In this embodiment, the opening and closing panel 3 is connected to the hinge assembly 7 so that the opening and closing panel 3 does not need to bear its own load. Therefore, setting the motor on the opening and closing panel 3 can make the structural strength of the fixed position of the motor better. In addition, the combined movement of the opening and closing panel 3 and the lifting panel 2 is realized by a single motor drive. A chute 31 is formed in the vertical direction at the middle position of the opening and closing panel 3. The output end of the motor is connected to a screw rod. A spiral guide rail is arranged on the outer side wall of the screw rod. A slider 62 is slidably arranged on the screw rod. The slider 62 circulates on the screw rod through a ball nut, so that the rotational movement of the motor can be converted into a linear movement. One end of the slider 62 away from the screw rod passes through the chute 31 and is fixedly installed with the lifting panel 2. The motor works to drive the slider 62 to rise and fall to drive the lifting panel 2 to synchronously rise and fall relative to the opening and closing panel 3, so that the opening and closing panel 3 makes an opening and closing movement. In this embodiment, the elastic element 63 is preferably a spring, but is not limited to a spring. A suitable elastic member can be selected according to actual needs. In this embodiment, the elastic element 63 is described by taking a spring as an example, and other types of elastic members will not be elaborated. In addition, since the mass of the lifting panel 2 itself is relatively large, during the single-motor drive process, the motor bears a large load, and jitter may occur more easily during movement, and the service life of the motor will also be affected. Therefore, springs are symmetrically arranged on both sides of the lifting panel 2. The upper end of the spring is connected to the opening and closing panel 3 through a fixed support, and the lower end of the spring is connected to the lifting panel 2 through a fixed support. When the lifting panel 2 is in the initial state, the spring is in a stretched state. When the lifting panel 2 rises, the spring slowly returns to its natural state, and the part of the gravity of the lifting panel 2 is balanced by the elastic force of the spring, so as to avoid jitter during movement due to excessive load.

[0046] Furthermore, a guiding slide rail 8 is further included. The guiding slide rail 8 is arranged on both sides of the opening and closing panel 3. The opening and closing panel 3 is slidably connected to the lifting panel 2 through the guiding slide rail 8. Its structure is simple, and it can ensure the stability of the relative sliding between the lifting panel 2 and the opening and closing panel 3.

[0047] Preferably, a limiting member is provided on the lifting panel 2, and the limiting member cooperates with the guiding slide rail 8 to limit the movement of the lifting panel 2. With reasonable design, the lifting of the lifting panel 2 can move according to a preset stroke.

[0048] In this embodiment, guiding slide rails 8 are symmetrically arranged on both sides of the opening and closing panel 3. The opening and closing panel 3 is slidably connected to the lifting panel 2 through the guiding slide rails 8, so as to guide the sliding movement between the lifting panel 2 and the opening and closing panel 3, and further ensure the stability of the relative sliding between the lifting panel 2 and the opening and closing panel 3. In addition, a limiting member is fixedly installed on the lifting panel 2 so that the lifting panel 2 moves up and down within a preset stroke range. The limiting member is preferably made of rubber material and is fixedly installed near the guiding slide rail 8, and is limited at a position 3 mm to 5 mm before the maximum position of the stroke of the lifting panel 2. The range hood controls the movement stroke of the lifting panel 2 by detecting the locked-rotor current of the motor at the limit position.

[0049] Specifically, it further includes baffles 32 arranged on both sides of the opening and closing panel 3. The smoke machine main body 1 has a smoke collecting cavity 12. The baffles 32 extend out of the smoke collecting cavity 12 or retract into the smoke collecting cavity 12 along with the flipping movement of the opening and closing panel 3. With simple structure and reasonable design, the baffles 32 and the opening and closing panel 3 can together form a smoke gathering plate to expand the smoke gathering area of the range hood.

[0050] Particularly, it further includes an oil cup 9, and the oil cup 9 is arranged at the bottom of the smoke machine main body 1. With reasonable design, it is convenient to collect the grease on the oil mesh 51.

[0051] In this embodiment, the baffle 32 extends outside the smoke collecting cavity 12 or retracts into the smoke collecting cavity 12 along with the flipping movement of the opening and closing panel 3. When the baffle 32 extends outside the smoke collecting cavity 12 along with the opening and closing panel 3, the baffle 32 and the opening and closing panel 3 together form a smoke gathering plate to expand the smoke gathering area of the range hood. At the same time, the oil net 51 is located at the lower position of the range hood main body 1, which can make the negative pressure area of the range hood main body 1 lower. In this way, the oil fume generated during the cooking process can be sucked and discharged clean before it spreads. In addition, a lighting lamp for illumination is adhesively fixed on the opening and closing panel 3, which is convenient for users to operate and thus improves the user experience. In addition, when the oil net 51 is in the open state, the oil net 51 is the main contact part with the oil fume. Since the oil net 51 is arranged to be inclined downward from the end close to the opening and closing panel 2 to the end close to the connecting rod 53, the grease condensed on the oil net 51 flows along the front and back direction of the oil net 51, then flows into the smoke collecting cavity 12 along the outer shell of the range hood main body 1, and finally is introduced into the bottom plate to enter the oil cup 9. In the closed state, since the end of the oil net 51 close to the opening and closing panel 2 is obliquely above the end close to the connecting rod 53, the condensed oil on the oil net 51 is directly introduced into the bottom plate to enter the oil cup 9. In this way, the range hood has a good oil path structure.

[0052] As Figure 6 shown, where the solid line is the open position of the component and the dotted line is the closed position of the component. The working principle of the range hood in this embodiment is as follows: The AB rod is the connecting rod 53, the BC rod is the oil net bracket 52, the CE rod is the opening and closing panel 3, and the DF rod is the support connecting rod 41. Among them, both point A and point F are hinged and installed on the range hood main body 1. When the driving device 61 drives the lifting panel 2 to move upward, through the action of the lifting panel 2, point D is driven to rotate clockwise around the hinge point F, thereby driving the CE rod to rotate clockwise around point E to push forward. In this way, through the action of the CE rod, point C is driven to move forward, and thus the flipping of the BC rod is realized.

[0053] The working steps of the range hood in this embodiment are as follows:

[0054] When the range hood is working, the lifting panel 2 moves upward under the action of the driving device 61. Through the action of the lifting panel 2, the support connecting rod 41 is driven to move obliquely upward, so that the opening and closing panel 3 flips outward. At the same time, the opening and closing panel 3 drives the oil net 51 to open the air inlet 11. The fan assembly of the range hood works to suck the air in the kitchen through the oil net 51 and discharge the oil fume to the common flue or outdoors. And after the oil net 51 is opened, the direction of the air inlet 11 is basically the same as the direction of the oil fume rising and is very close to the oil fume source, which can quickly suck in the oil fume. At the same time, the lifting panel 2 and the opening and closing panel 3 further play a role in blocking the oil fume from escaping forward; when the range hood stops working, the lifting panel 2 moves downward, and the support connecting rod 41 rotates along the rear lower direction to drive the opening and closing panel 3 to flip inward and close, thereby driving the oil net 51 to close.

[0055] With the above solution, compared with the prior art, when the range hood in this embodiment is in use, the compound movement of the lifting panel 2 and the opening and closing panel 3 drives the oil mesh 51 to turn outwards, and the cooking fumes are discharged outwards through the air inlet 11. And after the oil mesh 51 is opened, the direction of the air inlet 11 is basically the same as the direction of the rising fumes and is very close to the smoke source during cooking, so that the fumes can be quickly sucked in. At the same time, the lifting panel 2 and the opening and closing panel 3 further play a role in blocking the fumes from escaping forward, thereby greatly improving the fume suction effect.

[0056] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
