Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and more particularly to an oil fume extractor. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It can quickly remove waste from the stove and fumes produced during cooking and exhaust them outdoors, reducing pollution and purifying the air.

[0003] For example, Chinese utility model patent application number 202321627210.4 discloses a range hood, which includes: a smoke collection hood, in which a smoke collection chamber is formed inside the smoke collection hood, and an air outlet and an oil leakage hole that communicate with the smoke collection chamber are respectively opened at the top and bottom of the smoke collection hood, a smoke gathering chamber that opens towards the smoke inlet on the front of the smoke collection hood, a main smoke inlet that communicates with the smoke collection chamber is opened on the top surface of the smoke gathering chamber, and an oil return hole is opened on the rear wall of the smoke gathering chamber; and an oil filter that is detachably installed at the main smoke inlet.

[0004] The aforementioned patent features an oil mesh at the smoke inlet, located behind the smoke baffle. Cleaning requires removing the mesh and placing it in a water tank. However, the mesh is positioned in the customer's blind spot. Because the user cannot see its exact location, they can only roughly feel its position with their hands, resulting in grease getting onto their hands and causing discomfort. Alternatively, the user may bend over to observe the mesh's location and remove it, but since the smoke baffle remains open, there is a high risk of bumping their head and causing injury. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a range hood that allows for easy disassembly and assembly of the oil filter.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a range hood, comprising:

[0007] The smoke hood has a smoke inlet on its front side;

[0008] The oil filter can be positioned at the first position at the smoke inlet; and

[0009] The smoke baffle can open and close the smoke inlet. When the oil mesh is in the first position and the smoke baffle is in the open smoke inlet state, the smoke baffle is located in front of the oil mesh.

[0010] Its features are:

[0011] The oil mesh can also be positioned in a second position in front of the smoke inlet for easy disassembly and assembly. When the oil mesh is in the second position, it is located below the smoke baffle.

[0012] By allowing the oil filter to extend to the front of the smoke inlet, below the smoke baffle, the oil filter is exposed to the user's view and is no longer obstructed by the smoke baffle. This makes it easier for users to clean and disassemble the filter, and also avoids the risk of bumping their heads when bending over to remove the oil filter.

[0013] In order to drive the oil filter to move, the range hood also includes a motion mechanism that can drive the oil filter to switch between a first position and a second position.

[0014] In order to drive the oil filter to move, the motion mechanism includes a base and a telescopic linkage assembly. The base is located inside the smoke hood, and the linkage assembly is connected between the base and the oil filter.

[0015] To achieve the telescopic function of the linkage assembly, the linkage assembly includes a first link, a second link, a third link, a fourth link, a fifth link, a sixth link, a seventh link, an eighth link, a ninth link, and a tenth link. One end of the first link is rotatably connected to the base, and the other end of the first link is rotatably connected to one end of the second link. The other end of the second link is rotatably connected to one end of the third link. The other end of the third link is rotatably connected to one end of the fourth link. The other end of the fourth link is rotatably connected to one end of the fifth link. The other end of the fifth link is rotatably connected to the side of the oil filter facing the inside of the smoke collection hood. One end of the sixth link is rotatably connected to the base, and the other end of the sixth link is... One end of the seventh link is rotatably connected, the other end of the seventh link is rotatably connected to one end of the eighth link, the other end of the eighth link is rotatably connected to one end of the ninth link, the other end of the ninth link is rotatably connected to the side of the oil mesh facing the inside of the smoke hood, the body portion between the two ends of the second link is rotatably connected to the body portion between the two ends of the sixth link, the body portion between the two ends of the third link is rotatably connected to the body portion between the two ends of the seventh link, the body portion between the two ends of the fourth link is rotatably connected to the body portion between the two ends of the eighth link, one end of the tenth link is rotatably connected to the end of the eighth link away from the seventh link, and the other end of the tenth link is rotatably connected to the body portion between the two ends of the fifth link.

[0016] In order to drive the linkage assembly to extend and retract, the motion mechanism also includes a motor, an eleventh link, and a twelfth link. The motor is mounted on the base and includes a motor shaft. One end of the eleventh link is fixedly connected to the motor shaft, and the other end of the eleventh link is rotatably connected to one end of the twelfth link. The other end of the twelfth link is rotatably connected to the body portion between the two ends of the first link.

[0017] To make the oil mesh more stable when moving, the combination of the base, connecting rod assembly, eleventh connecting rod and twelfth connecting rod has two sets, one set and the electric mechanism form the active end, and the other set forms the driven end. The active end and the driven end are respectively arranged on the left and right sides of the oil mesh.

[0018] The motion mechanism also includes a synchronous shaft for synchronizing the action of the active end and the driven end. The synchronous shaft is rotatably disposed between two bases. One end of the synchronous shaft is connected to the motor shaft of the motor. The ends of the eleventh links of the active end and the driven end that are away from the twelfth link are fixedly connected to the synchronous shaft.

[0019] To achieve the connection between the oil filter and the connecting rod assembly, the range hood also includes an oil filter bracket disposed between the connecting rod assembly and the oil filter. The oil filter bracket includes a first connecting part connected to the oil filter and a second connecting part connected to the connecting rod assembly. The second connecting part extends from the first connecting part in a direction away from the oil filter. The end of the fifth connecting rod away from the fourth connecting rod is rotatably connected to the second connecting part. The end of the ninth connecting rod away from the eighth connecting rod is rotatably connected to the second connecting part. The connection point between the fifth connecting rod and the second connecting part is higher than the connection point between the ninth connecting rod and the second connecting part.

[0020] To enable quick assembly and disassembly of the oil filter, one end of the first connecting part is provided with a tongue, and the other end of the first connecting part is provided with a first magnetic suction element. The oil filter is provided with a socket that engages with the tongue and a second magnetic suction element that engages with the first magnetic suction element.

[0021] Furthermore, on a vertical plane parallel to the left-right direction of the range hood, when the oil mesh is in the first position and the smoke baffle is in the open state, the projection of the oil mesh on the vertical plane falls within the projection range of the smoke baffle on the vertical plane.

[0022] Compared with existing technologies, the advantages of this invention are as follows: By allowing the oil filter to extend to the front of the smoke inlet, below the smoke baffle, the oil filter is exposed to the user's view and is no longer obstructed by the smoke baffle, thus facilitating cleaning and disassembly, and avoiding the risk of bumping one's head when bending over to remove the oil filter. The oil filter and the oil filter bracket are fixed together by a tongue and a magnetic attraction, making it easy to install and remove the oil filter. Attached Figure Description

The other end of the twelfth link 35 is rotatably connected to the body portion between the two ends of the first link 331.

[0039] The aforementioned combination of base 31, link assembly 33, eleventh link 34, and twelfth link 35 comprises two sets. One set, together with motor 32, constitutes the driving end, while the other set constitutes the driven end. The motion mechanism also includes a synchronous shaft 36 for synchronizing the actions of the driving and driven ends. The synchronous shaft 36 is rotatably disposed between the two bases 31.

[0041] One end of the first connecting part 41 is provided with a tongue 411, and the other end of the first connecting part 41 is provided with a first magnetic member 412. The oil mesh 2 is provided with a socket 21 that engages with the tongue 411 and a second magnetic member 22 that magnetically engages with the first magnetic member 412.

[0042] See Figure 7During cleaning, pressing the cleaning button opens the smoke baffle 5 to its maximum position, then the oil filter 2 extends forward (from its top in the first position to its front in the second position). Once in its final position, the smoke baffle 5 returns to its half-position, at which point the oil filter 2 is located below the smoke baffle 5 and partially extends forward beyond it, thus being fully exposed and easily accessible for the user. The oil filter 2 is fixed to the oil filter bracket 4 using a tongue and magnetic attraction. During installation, first insert the oil filter 21 into the tongue 411 of the oil filter bracket 4, then magnetically engage the first magnetic attraction component 412 with the second magnetic attraction component 22. Extending the oil filter 2 facilitates cleaning and disassembly, while also avoiding the risk of bumping one's head when bending over to retrieve it.
