[0028] Example:

[0029] like Figures 1 to 4 As shown, this embodiment provides a range hood, comprising:

[0030] A smoke collecting hood 1, wherein a smoke collecting cavity 11 is defined in the smoke collecting hood 1, and a smoke inlet 12 connected to the smoke collecting cavity 11 is provided on the front wall at the lower end of the smoke collecting hood 1;

[0031] A flap 2, the upper end of which is hinged to the upper end of the smoke collecting hood 1 to open and close the smoking port 12;

[0032] The inner cover 3 has a mounting opening on the front wall of the upper end of the smoke collecting cover 1. The front end of the inner cover 3 is connected to the flap 2, and the rear end thereof is movably connected to the smoke collecting chamber 11 so that the flap 2 drives the inner cover 3 to extend out of the mounting opening or retract into the smoke collecting chamber 11.

[0033] The oil fume channel 4 has a smoke inlet 31 on the bottom wall of the inner cover 3 . The oil fume channel 4 is arranged inside the inner cover 3 , and the smoke inlet end of the oil fume channel 4 is connected to the smoke inlet 31 , and the smoke outlet end of the oil fume channel 4 is connected to the smoke collecting chamber 11 .

[0034] The hood 3 is provided with a smoke inlet 31 and a smoke outlet 12, and the smoke inlet 31 and the smoke outlet 12 are provided at the bottom wall of the hood 3. The smoke inlet 31 and the smoke outlet 12 are connected to each other through the smoke outlet 4. The smoke inlet 31 and the smoke outlet 12 are connected to each other through the smoke outlet 4. The range hood has both the top and side smoke intake functions. The inner hood 3 is driven forward through the flipping movement of the flap 2 to extend the inner hood 3 out of the mounting opening, thereby synchronously opening the smoke inlet 31 and the smoke outlet 12, and then a part of the smoke generated by cooking enters the smoke collecting chamber 11 through the smoke outlet 12, and the other part enters the smoke collecting chamber 11 through the smoke inlet 31 and the smoke outlet 12 in turn, or drives the inner hood 3 to move backward through the mounting opening to retract the inner hood 3 into the smoke collecting chamber 11, thereby synchronously closing the smoke inlet 31 and the smoke outlet 12. The range hood has a simple structure, which can further improve the smoke collection effect of the range hood, thereby effectively reducing the occurrence of smoke escape.

[0035] Furthermore, it also includes an isolation cover 5, which is arranged at an internal position of the inner cover 3. A cavity is defined in the isolation cover 5 to form an oil fume channel 4, and the oil fume channel 4 and the internal space of the inner cover 3 are independently spaced apart.

[0036] In this embodiment, since a accommodating cavity is defined at an internal position of the inner cover 3, the isolation cover 5 is arranged in the accommodating cavity, and a cavity is defined in the isolation cover 5 so that the cavity forms an oil fume passage 4. The isolation cover 5 is used to allow the oil fume passage 4 and the internal space of the inner cover 3 to be independently spaced apart, that is, the oil fume passage 4 and the accommodating cavity of the inner cover 3 are not connected together, thereby isolating the oil fume in the oil fume passage 4 from the accommodating cavity of the inner cover 3, thereby preventing the oil fume from entering the accommodating cavity area of ​​the inner cover 3.

[0037] Preferably, an oil retaining edge 51 is bent from front to back on the left end and / or right end of the front wall of the isolation cover 5 , and the surface of the oil retaining edge 51 is attached to the left wall and / or right wall of the isolation cover 5 .

[0038] Specifically, an oil-blocking portion is bent from the back to the front on the left wall and / or the right wall of the isolation cover 5 , and the surface of the oil-blocking portion is attached to the front wall of the isolation cover 5 .

[0039] Preferably, an oil guide plate 53 is further included, and a smoke exhaust port 52 communicating with the smoke collecting chamber 11 is opened at the rear end of the isolation cover 5. The fixed end of the oil guide plate 53 is connected to the upper end of the smoke exhaust port 52, and the free end thereof extends from front to back and downward.

[0040] In the present embodiment, since the shape of the isolation cover 5 is preferably a rectangle, but not limited to a rectangle, other more suitable shapes can be selected according to actual needs. In the present embodiment, the shape of the isolation cover 5 is described by taking a rectangle as an example, and other shapes are not repeated. When the shape of the isolation cover 5 is a rectangle, the isolation cover 5 has a left wall and a right wall that are arranged correspondingly. Since the bottom wall and the rear wall of the isolation cover 5 are both open to form an opening, the isolation cover 5 also has a front wall and a top wall, and the opening at the lower end of the isolation cover 5 is arranged at the position of the smoke inlet 31 so that the oil fume channel 4 in the isolation cover 5 is connected to the smoke inlet 31, and at the same time, the opening at the rear end of the isolation cover 5 is connected to the smoke collecting chamber 11 so that the oil fume channel 4 in the isolation cover 5 is connected to the internal space of the smoke collecting chamber 11, so that the smoke inlet 31 and the smoke collecting chamber 11 are connected to each other through the oil fume channel 4 in the isolation cover 5.

[0041] In addition, since the isolation cover 5 is formed by sheet metal processing, in order to prevent oil droplets from seeping out from the splicing gap between the adjacent two side walls of the isolation cover 5, an oil retaining edge 51 is bent from front to back on the left end and / or right end of the front wall of the isolation cover 5, and the surface of the oil retaining edge 51 is attached to the left wall and / or right wall of the isolation cover 5, so that the oil retaining plates at the left and right ends of the front wall of the isolation cover 5 are correspondingly attached to the side walls of the isolation cover 5, thereby preventing oil droplets from seeping out from the front wall, left wall, and right wall of the isolation cover 5. At the same time, the laser welding process of the gap can be eliminated to reduce the manufacturing cost. Of course, in order to achieve the same technical effect, an oil baffle is provided on the left wall and / or the right wall of the isolation cover 5, and the surface of the oil baffle is attached to the front wall of the isolation cover 5, so that the oil baffles on the left and right side walls of the isolation cover 5 are correspondingly attached to the front wall of the isolation cover 5, thereby preventing oil droplets from seeping out of the splicing gaps between the front wall, left wall and right wall of the isolation cover 5.

[0042] More preferably, if the rear end of the isolation cover 5 is not open, a smoke exhaust port 52 connected to the smoke collecting chamber 11 is opened at the rear end of the isolation cover 5, and the fixed end of the oil guide plate 53 is connected to the upper end of the smoke exhaust port 52, and the free end thereof extends from front to back and downward, so that the grease on the oil guide plate 53 can flow into the smoke collecting chamber 11 when the smoke inlet 31 is opened and closed.

[0043] Furthermore, a connecting component is included, through which the isolation cover 5 is installed on the inner cover 3.

[0044] Specifically, it also includes a fixing seat 7, which is arranged at an internal position of the inner cover 3, a mounting hole 71 is opened on the fixing seat 7, and a connecting hole 54 is opened on the isolation cover 5. The connecting member passes through the connecting hole 54 and is connected with the mounting hole 71.

[0045] Preferably, a smoke outlet 32 ​​is provided on the rear wall of the inner cover 3 , and the oil smoke passage 4 is connected to the smoke collecting chamber 11 through the smoke outlet 32 ​​.

[0046] In this embodiment, a fixing seat 7 is protruded upward on the bottom wall of the inner space of the inner cover 3, and a mounting hole 71 is provided on the fixing seat 7. A connecting hole 54 is provided on the front wall of the isolation cover 5, and the connecting member is connected to the mounting hole 71 after passing through the connecting hole 54. More preferably, a mounting seat is protruded outward on the left and right sides of the rear end of the isolation cover 5, and a through hole is provided on the mounting seat. At the same time, a matching hole is provided on the rear wall of the inner cover 3, so that the connecting member can pass through the through hole and connect with the matching hole, thereby installing the isolation cover 5 in the inner space of the inner cover 3. In addition, a smoke outlet 32 ​​can be provided on the rear wall of the inner cover 3, and the oil smoke channel 4 is connected to the smoke collecting chamber 11 through the smoke outlet 32, so that the external oil smoke passes through the smoke inlet 31, the oil smoke channel 4, and the smoke outlet 32 ​​in sequence and then flows into the smoke collecting chamber 11.

[0047] Furthermore, it also includes an electric control component 6 , which is arranged at an inner position of the inner cover 3 and is located outside the oil fume passage 4 .

[0048] In particular, the electric control assembly 6 at least includes a switch panel 61 and / or an illumination lamp 62 disposed inside the inner cover 3 , wherein the switch panel 61 is connected to the flap 2 , and / or the illumination lamp 62 is connected to the bottom wall of the inner cover 3 .

[0049] In the present embodiment, in order to prevent grease from damaging the electric control component 6, the electric control component 6 can be arranged in the internal space of the inner cover 3, that is, a switch panel 61 and / or a lighting lamp 62 are respectively arranged at the internal position of the inner cover 3, wherein the switch panel 61 is connected to the flap 2, and / or the lighting lamp 62 is connected to the bottom wall of the inner cover 3. Since the internal space of the inner cover 3 itself is a relatively closed cavity, the grease in the smoke collecting chamber 11 can be prevented from entering the internal space of the inner cover 3. At the same time, the isolation cover 5 is used to isolate the oil smoke in the oil smoke channel 4 from entering the internal space of the inner cover 3, so that the oil smoke in the oil smoke channel 4 can be isolated from the electric control component 6, thereby preventing the oil smoke from entering the installation area of ​​the electric control component 6. In this way, the oil smoke can be prevented from damaging the electric control component 6, and the service life of the electric control component 6 can be further improved.

[0050] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
