The embodiment provides an air inlet pipeline of a range hood, and fig. 1 and 2 are schematic structural diagrams of the air inlet pipeline mounted on the range hood. As shown in fig. 1 and 2, the range hood includes a housing 100, and a smoke collecting cavity 101 is concavely disposed at the bottom of the housing 100 for collecting the oil smoke. The air inlet pipeline comprises a cover body structure 1 and an air inlet pipe 2, wherein the cover body structure 1 is arranged in the smoke collecting cavity 101 and used for connecting the shell 100 and the air inlet pipe 2, and the upper end of the air inlet pipe 2 is fixedly connected with the cover body structure 1. The air inlet pipe 2 comprises at least two layers of air inlet branch pipes which are sleeved with each other and can stretch out and draw back. Preferably, as shown in fig. 3, the air inlet pipe 2 in this embodiment includes three layers of air inlet branch pipes, specifically, a first branch pipe 21, a second branch pipe 22 and a third branch pipe 23 which are sequentially arranged from the cover body structure 1 to the direction of the kitchen range, wherein the diameter of the first branch pipe 21 is larger than that of the second branch pipe 22, and the diameter of the second branch pipe 22 is larger than that of the third branch pipe 23, so as to ensure the telescoping reliability and the smoothness of the air flow of the air inlet pipe 2. As shown in fig. 5 and 6, a first groove structure 24 is arranged at the connection position of the first branch pipe 21 and the second branch pipe 22, a second groove structure 25 is arranged at the connection position of the second branch pipe 22 and the third branch pipe 23, and the groove structures are used for storing oil stains when the range hood works so as to prevent the oil stains from polluting the air inlet pipe 2 or dripping on a kitchen range; when the range hood is closed, the oil dirt stored in the groove structure can flow to the upper part of the hood body structure 1 along with the shrinkage of the air inlet pipe 2, and then flows into an oil cup of the range hood.
The hood body structure 1 is connected with the smoke collecting cavity 101 of the range hood, the telescopic air inlet pipe 2 is arranged in the hood body structure 1, and the air inlet pipe 2 extends downwards to be closer to a kitchen range in the cooking process, so that the range hood can suck the oil smoke into the range hood when the oil smoke is in a frying state and before the oil smoke rises, and further, a better oil smoke sucking effect is achieved on the premise that the redundant air quantity is not needed; when cooking is finished, the air inlet pipe 2 is retracted into the smoke collecting cavity 101, so that the appearance and the size of the range hood are not affected. Therefore, the invention reduces the air quantity, prolongs the service life of the motor and reduces the noise under the condition of ensuring the performance of the range hood.
Preferably, as shown in fig. 4, the cover structure 1 has an axisymmetric structure, and includes a mounting hole 11 at the center and four baffles disposed around the mounting hole 11, where the four baffles are sequentially connected to form a cavity with an opening at the lower end for collecting oil smoke; further, the four baffles are all arranged in a downward and outward inclined mode through the mounting holes 11, so that the inlet size of air flow is increased, and the smoke collecting capacity of the range hood is improved. The cover body structure 1 is fixedly connected with the smoke collecting cavity 101 of the range hood through the bottom edges of the baffles, and can be fastened through screws; the mounting hole 11 of the cover body structure 1 is fixedly connected with the upper end of the air inlet pipe 2, and specifically, screw connection or welding can be adopted. In addition, a plurality of ventilation holes 12 are uniformly formed in the cover body structure 1 and around the mounting holes 11, and are used for assisting in sucking and collecting redundant oil smoke in the smoke cavity 101 so as to prevent the phenomenon that the oil smoke is large and the oil smoke is not thoroughly sucked by the air inlet pipe 2 during quick frying. Preferably, the number of the ventilation holes 12 in the embodiment is ten, three of the four baffles are respectively arranged on the two longer baffles, two of the two shorter baffles are respectively arranged, and the diameter of the ventilation holes 12 is preferably 10mm, so as to achieve the best smoke collecting effect.
In the invention, the telescopic movement of the air inlet pipe 2 can be realized by adopting a manual mode for pushing and pulling, and can also be driven by adopting a driving device. Preferably, the driving device is provided in this embodiment, and the extending end of the driving device is connected with other air inlet branch pipes except the uppermost air inlet branch pipe in the air inlet pipe 2, so as to drive the corresponding air inlet branch pipe to realize telescopic movement. Here, the driving device may be a driving cylinder mechanism, or may be a mechanism in which a motor is matched with a rack and pinion, or a mechanism in which a motor is matched with a screw nut, so long as the driving device can drive the air inlet branch pipe to do linear reciprocating motion, and in this embodiment, the driving cylinder mechanism is selected. Further, the driving cylinder mechanism comprises a first cylinder 31 and a second cylinder 32, wherein the body of the first cylinder 31 is fixed at the bottom outside the first branch pipe 21, and the extending end of the first cylinder 31 is fixed at the bottom outside the second branch pipe 22, so that when the piston rod of the first cylinder 31 moves, the second branch pipe 22 can be driven to stretch; the body of the second cylinder 32 is fixed on the top of the inner side of the second branch pipe 22, and the extension end of the second cylinder 32 is fixed on the top of the inner side of the third branch pipe 23, so that when the piston rod of the second cylinder 32 moves, the third branch pipe 23 can be driven to stretch and retract. In addition, a distance sensor, such as a magnetic induction coil, a magnetic induction ring, etc., is further installed at the bottom of the third branch pipe 23, so as to sense the distance from the bottom of the air inlet pipe 2 to the kitchen range, so as to ensure that the air inlet pipe 2 is always at an optimal height, and effectively improve the effect of fume exhaust of the air inlet pipe.
Specifically, the wall thickness of the air inlet pipe 2 is 1mm, the length of the first branch pipe 21 is 100mm, and the diameter is 104mm; the second branch pipe 22 has a length of 150mm and a diameter of 92mm; the third branch 23 has a length of 152mm and a diameter of 80mm. The arrangement ensures that when the air inlet pipe 2 is in a fully extended state, the total length of the air inlet pipe is kept at about 400mm, and the distance from the smoke collecting cavity 101 of the range hood to a kitchen range is 650mm-700mm, so that the distance from the bottom end of the third branch pipe 23 to the kitchen range is 250mm-300mm in the extended state, and the position is just in a frying state of lampblack, so that the collecting effect of lampblack is better, and the lampblack absorbing capacity of the range hood can be effectively enhanced on the premise of not changing the air quantity of the range hood. In addition, the depth of the smoke collecting cavity 101 of the embodiment is larger than the length of the air inlet pipe 2 in the fully contracted state, so that the air inlet pipe 2 is in a hidden state in the head-up state, and a user cannot see the air inlet pipe 2, thereby improving the aesthetic property of the range hood.
The embodiment also provides a range hood, which is not provided with an oil net, but adopts the air inlet pipeline of the range hood to replace the oil net, and is also provided with an impeller and a net disc structure in a centrifugal air duct so as to realize the separation effect on oil fume. The working process of the range hood is as follows: firstly starting the range hood, then controlling the second branch pipe 22 to slide downwards by the driving device, and then controlling the third branch pipe 23 to slide downwards, detecting the distance between the range hood and a kitchen range in real time by a distance sensor at the lower end of the third branch pipe 23 in the sliding process, and adjusting the telescopic length of the air inlet pipe 2 according to the detected distance; when cooking is finished, the range hood is closed, and the air inlet pipe 2 is retracted into the cover body structure 1 (as shown in fig. 7). Because the range hood absorbs the oil smoke cleanly in the oil smoke frying stage, the effect of oil smoke suction is greatly enhanced, and the air quantity of the range hood can be properly reduced according to the needs, so that the noise of the range hood is reduced.
