Description

Technical Field

[0001] This utility model relates to the field of range hoods, and in particular to a flip-type range hood. Background Technology

[0002] Traditional range hoods primarily consist of a control panel and an exhaust duct. The control panel captures cooking fumes, and the pre-filtered gas is exhausted through the exhaust duct. Current products generally use a fixed design, with the angle between the control panel and the horizontal plane preset to a theoretically optimal value of 45°. However, in actual cooking conditions, fumes may exceed the static coverage area of ​​the control panel, causing fumes to escape from the edges, making it difficult to achieve a fast and thorough fume capture effect.

[0003] Based on the above, the existing flip-type range hoods need further improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a flip-up range hood. The panel can be flipped at multiple angles through a rocker mechanism, so that the panel can be flipped to the smoke collection area for targeted suction, thereby improving the oil fume capture effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flip-up range hood, including a panel, a suction duct, and a rocker mechanism. The panel is a hollow structure, and the suction duct is connected to the panel through a connecting part. The connecting part is rotatably mounted on the suction duct through the rocker mechanism and drives the panel to flip.

[0006] This invention utilizes a rocker mechanism to achieve multi-angle adjustment of the panel, allowing it to rotate freely. This overcomes the limitations of traditional fixed-angle range hoods, enabling dynamic directional suction and improving the efficiency of fume collection. Compared to existing technologies, the rotating range hood of this invention offers higher suction efficiency, better suction effect, and a superior user experience.

[0011] Preferably, a first rotating rod and a second rotating rod are provided between the two side walls of the connecting part. The first rotating rod passes through the first limiting groove, and the second rotating rod passes through the second limiting groove. The first connecting rod is rotatably mounted on the first rotating rod, and the connecting part is rotatably mounted on the second rotating rod. The first rotating rod limits the first limiting plate, and the second rotating rod limits the second limiting plate, so that one end of the first limiting plate and the second limiting plate are connected to the connecting part.

[0012] Preferably, the suction duct is formed by a partition, and a baffle is provided on the suction duct to divide the suction duct into an intake duct and an outlet duct. The intake duct is connected to the panel through a connecting part, and the outlet duct is connected to the outside.

The air inlet of the blower is located on the air intake duct, and its air outlet is installed on the mounting hole and communicates with the air outlet duct. The electrical control box is located on the air outlet duct through the baffle. The blower draws in external oil fumes through the connecting part and the panel and discharges them through the air outlet and the air outlet duct.

[0014] Preferably, the baffle is provided with a flange, and the baffle is fixed to the suction duct by the flange.

[0015] Preferably, it also includes a hook component, which has at least one hook, and the suction duct has a positioning hole that is adapted to the hook. The suction duct is hung on the hook component through the positioning hole. Attached Figure Description

[0027] See Figures 1 to 4 This utility model discloses a flip-up range hood 1, including a panel 2, a suction duct 3 and a rocker mechanism 4. The panel 2 is a hollow structure. The suction duct 3 is connected to the panel 2 through a connecting part 5. The connecting part 5 is rotatably mounted on the suction duct 3 through the rocker mechanism 4 and drives the panel 2 to flip.

[0028] See Figure 4 The rocker mechanism 4 includes a first link assembly 6 and a second link assembly 7. The first link assembly 6 includes a first link 61 and a second link 62. One end of the first link 61 is hinged to the second link 62, and the other end is rotatably mounted on the connecting part 5. The other end of the second link 62 is rotatably mounted on the suction duct 3. The second link assembly 7 includes a connecting plate 71, a third link 72, and a fourth link 73.

In this design, the positions of the two end points of the first link assembly 6 are fixed, while the internal hinges of the first link assembly 6 and the second link assembly 7 are slidable. This allows the panel 2 to remain connected to the suction duct 3 while being able to rotate within a certain angle range, thereby aligning the suction angle of the panel 2 with the position of the smoke, achieving directional suction of the smoke, and resulting in better suction effect.

[0029] See Figures 3 to 4 The first connecting rod assembly 6 and the second connecting rod assembly 7 are symmetrically arranged in the suction duct 3.

The first hinge point 63 is slidably disposed on the first limiting groove 411, and the second hinge point 74 is slidably disposed on the second limiting groove 421. In this design, the first limiting groove 411 and the second limiting groove 421 are used to limit the movement trajectory of the first hinge point 63 and the second hinge point 74, so that the connecting part 5 drives the panel 2 to rotate smoothly.

[0032] See Figure 7 Specifically, the first limiting plate 41 is set in the shape of a "┐" and the second limiting plate 42 is set in the shape of a strip.

The edge of ventilation opening 21 extends toward the suction duct 3 to form connecting part 5. Connecting part 5 is disposed in the suction duct 3. When panel 2 is flipped, connecting part 5 surrounds and connects panel 2 and suction duct 3.

[0035] See Figures 3 to 6 To position the connecting part 5 to the first limiting groove 411 and the second limiting groove 421, a first rotating rod 51 and a second rotating rod 52 are provided between the two side walls of the connecting part 5.

[0038] See Figure 3 The suction duct 3 is formed by a partition, and a baffle 31 is provided on the suction duct 3. The baffle 31 divides the suction duct 3 into a suction duct 32 and an exhaust duct 33.
