Description

Technical Field

[0001] The utility model belongs to the technical field of range hoods, and particularly relates to a range hood. Background Art

[0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction type and near (side)-suction type. The near-suction type range hood uses the principle of eddy current wind pressure to absorb most of the oil fumes close to the cooking range in an arc shape, which can reduce the adverse effects on human health.

[0003] At present, a smoke baffle is arranged at the air inlet of the range hood. Driving the smoke baffle to rotate outward to open the air inlet or driving the smoke baffle to rotate inward to close the air inlet has the following defects in the use process: during the process of the smoke baffle opening outward, it is easy to collide with cookware with a relatively high height, and only cookware with a relatively low height can be used, so the applicability is limited; after the smoke baffle opens outward, the top edge of the smoke baffle is easy to interfere with the bottom of the upper cabinet or the door of the cabinet. Therefore, a certain gap needs to be reserved between the top of the body and the bottom of the cabinet, but the existence of the gap is likely to cause dust accumulation and is not easy to clean.

[0004] The existing patent document (publication number: CN207539970U) discloses "a near-suction type range hood", which also has the above technical problems. Summary of the Invention

[0005] The purpose of the utility model is to solve the above technical problems existing in the prior art, and provide a range hood with novel structure, which can change the shielding area of the smoke baffle for the air inlet, and further change the smoke inlet area of the air inlet, and is suitable for different oil fume conditions; compared with the existing flip-type smoke baffle, the smoke baffle will not collide with cookware with a relatively high height, and can be suitable for cookware with a relatively high height, and has strong applicability.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

The structure of this oil fume extractor is novel, it can change the shielding area of the smoke baffle for the air inlet, and then change the smoke inlet area of the air inlet, which is suitable for different oil fume conditions; compared with the existing flip-type smoke baffle, the smoke baffle will not collide with cookware with a relatively high height, and it can be applied to cookware with a relatively high height, with strong applicability.

[0008] Further, the body is provided with a smoke gathering part extending horizontally outwards, and a smoke inlet hole is provided on the bottom surface of the smoke gathering part. During the smoking process, most of the oil fume is sucked into the flue through the air inlet, and a small part of the oil fume continues to rise and is sucked into the flue through the smoke inlet hole, forming a double air inlet structure, which has the functions of top suction and side suction, effectively preventing the oil fume from escaping to both sides, and improving the smoking efficiency and smoking effect.

[0009] Further, the air inlet is separated into two smoke inlets communicating with the flue by a partition plate, a protective cover is provided in the flue, the protective cover divides the flue into two smoke exhaust chambers communicating with the smoke exhaust port, and the protective cover cooperates with the partition plate to cover the driving mechanism.

[0010] Further, a connecting piece is provided on the back surface of the smoke baffle, the connecting piece includes a first panel and an L-shaped base, the smoke baffle is fixed on the first panel, the first panel is fixed on the L-shaped base, and both the first V-shaped block and the second V-shaped block are rotatably connected between the L-shaped base and the transmission seat. The structure of the connecting piece is simple. The L-shaped base connects the smoke baffle through the first panel, with a large contact area and high connection strength, which is beneficial to the transmission of force, and thus drives the smoke baffle to move more smoothly.

[0011] Further, the connecting rod component includes a first connecting rod and a second connecting rod, the output end of the driving component is rotatably connected to the first connecting rod, the first connecting rod is rotatably connected to the second connecting rod, and the second connecting rod is rotatably connected to the transmission seat.

During the installation of the oil cup, the inner fold is placed in the escape gap, so that the lower convex is in conflict with the elastic arch, and the elastic arch is pressed down by the lower convex so that the elastic arch no longer blocks the lower convex. After the lower convex passes through the elastic arch, the elastic arch returns to its original state, blocking the lower convex from retreating, and cooperates with the blocking effect of the wall on the oil cup to achieve the oil cup being limited at the bottom of the machine body, replacing the bolt fixing method, and the disassembly and assembly is labor-saving and convenient.

[0014] Furthermore, the front side of the oil cup extends upward to form a positioning part. During the installation of the oil cup, the lower convex part first meets the elastic arched part, and then the lower convex part presses down the elastic arched part and then passes over the elastic arched part. The elastic arched part returns to its original state and blocks the lower convex part from retreating. When the positioning part sticks to the front bottom of the body, it indicates that the installation is in place. At this time, the positioning part blocks the oil cup from continuing to move backward. The oil cup is blocked at the same time, front, back, left, and right, and cannot move freely, and the installation stability is high.

[0015] Furthermore, a guide rail is provided in the flue, and the transmission seat is slidably connected to the guide rail through a slider, so that the transmission seat can slide in a directional manner without shaking left and right, and has high stability, and the transmission seat is limitedly connected to the guide rail and cannot be freely separated from the guide rail.

[0019] 2. During the smoking process, most of the oil smoke is sucked into the flue through the air inlet, and a small part of the oil smoke continues to rise and is sucked into the flue through the smoke inlet hole, forming a double air inlet structure with the functions of top suction and side suction, effectively preventing the oil smoke from escaping to both sides, and improving the smoking efficiency and smoking effect.

[0020] 3. The protective cover cooperates with the partition to cover the driving mechanism, which plays a certain protective role on the driving mechanism, reduces the oil smoke from infecting the driving mechanism, and thus reduces the failure rate of the driving mechanism.

[0021] 4. The air inlet is divided into two left and right smoke inlets communicated with the flue by a partition. The protective cover divides the flue into two left and right smoke exhaust chambers communicated with the smoke exhaust port.

[0041] As Figure 9 and Figure 10As shown, when the air inlet 4 is closed, the second V-block 13 conflicts with the stop pin 9, and the driving assembly 10 starts and drives the first connecting rod 15 to rotate, and the first connecting rod 15 drives the second connecting rod 16 to swing, and the second connecting rod 16 pulls up the transmission seat 11 to move the transmission seat 11 upward.

Figure 1 and Figure 3 shown.

[0044] The connecting member 20 has a simple structure, and the L-shaped base 22 is connected to the smoke baffle 7 through the first panel 21. The contact area is large and the connection strength is high, which is conducive to the transmission of force and thus drives the smoke baffle 7 to move more smoothly.

During the smoking process, most of the oil smoke is sucked into the flue through the air inlet 4, and a small part of the oil smoke continues to rise and is sucked into the flue through the smoke inlet hole 24, forming a double air inlet structure with the functions of top suction and side suction, effectively preventing the oil smoke from escaping to both sides, and improving the smoking efficiency and smoking effect.
