Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 to 4, fig. 1 and 2 show two different viewing angle structural schematic diagrams of a range hood in an embodiment of the present invention, fig. 3 shows a structural schematic diagram of a range hood with a first back panel 13 hidden, and fig. 4 shows a cross-sectional view of the range hood. The first housing 10 is formed with a first air inlet 111, a first air outlet 121, and a flue gas channel communicating the first air inlet 111 and the first air outlet 121. The two first air deflectors 30 are arranged in the flue gas channel, and the two first air deflectors 30 are arranged oppositely. One end of each of the two first air deflectors 30 is located at or passes through the first air outlet 121. The other ends of the two first air deflectors 30 are disposed on two opposite sidewalls of the first casing 10, and are opposite to the first air inlet 111. The distance between the two first air deflectors 30 gradually decreases along the direction from the first air inlet 111 to the first air outlet 121. The distance S1 between the other ends of the two first air deflectors 30 is greater than the distance S2 between the two opposite sides of the first air outlet 121.

When the range hood works, after oil smoke enters the first shell 10 through the first air inlet 111, the oil smoke flows into the first air outlet 121 and then encounters the two first air deflectors 30 which are arranged oppositely, the two first air deflectors 30 cooperate with the back panel to guide the oil smoke to the first air outlet 121 and discharge the oil smoke outwards, the distance between the two first air deflectors 30 is gradually reduced in the direction close to the first air outlet 121, the effects of gathering and guiding the oil smoke are achieved, and the exhaust fan can conveniently extract the oil smoke in the first shell 10 outwards through the first air outlet 121. In addition, the other ends of the two first air deflectors 30 are respectively arranged on two opposite side walls of the first shell 10 and are opposite to the first air inlet 111, so that all the gas in the flue gas channel can be kept together under the action of the two first air deflectors 30; two first aviation baffles 30 one end are located or wear to establish first air outlet 121, can guarantee that all gas can both follow the inside outflow of first air outlet 121, can not have the flue gas to reveal from the edge of first air outlet 121. Therefore, compared with the conventional range hood, the two first air deflectors 30 are additionally arranged in the first shell 10, and the two first air deflectors 30 can be used for conveniently pumping and discharging oil smoke outwards, so that the working power of the range hood can be reduced to a certain extent, the noise can be effectively reduced, the service life of the range hood can be prolonged, and the energy source can be saved.

In a specific embodiment, the range hood further includes a second air deflector 20. The second air guiding plate 20 is disposed in the flue gas channel, and is located between the first air inlet 111 and the first air guiding plate 30, for guiding the flue gas from the first air inlet 111 to the first air guiding plate 30. When the range hood works, after oil smoke enters the first shell 10 through the first air inlet 111, the oil smoke can meet the second air deflector 20 arranged at an included angle with the first back panel 13, and the second air deflector 20 plays a role in guiding the oil smoke; before the oil smoke flows to the first air outlet 121, the oil smoke encounters the two first air deflectors 30 which are arranged oppositely, the two first air deflectors 30 cooperate with the back panel to guide the oil smoke to the first air outlet 121 and discharge the oil smoke outwards, the distance between the two first air deflectors 30 is gradually reduced in the direction close to the first air outlet 121, the effects of gathering and guiding the oil smoke are achieved, and the oil smoke in the first shell 10 is conveniently drawn out through the first air outlet 121 by the exhaust fan. Therefore, compared with the conventional range hood, the second air guide plate 20 and the two first air guide plates 30 are additionally arranged in the first shell 10, and the second air guide plate 20 and the two first air guide plates 30 can be used for conveniently pumping and discharging the oil smoke outwards, so that the working power of the range hood can be reduced to a certain extent, the noise can be effectively reduced, the service life of the range hood can be prolonged, and the energy can be saved.

In one embodiment, the first air guiding plate 30 is any one or more combination of a flat plate, an arc plate and a folding plate. When the first air guiding plate 30 is an arc-shaped plate, the first air guiding plate 30 is recessed in a direction away from the first air guiding plate 30 opposite to the first air guiding plate. When the first air guiding plates 30 are straight plates, the two first air guiding plates 30 are arranged at an included angle.

Specifically, the first casing 10 includes a first front surface 11, a first top surface 12 connected to the first front surface 11, and a first rear surface 13 provided at a distance from the first front surface 11. The first air inlet 111 is formed on the first front panel 11, and the first air outlet 121 is formed on the first top panel 12.

It should be noted that the first front panel 11 refers to a panel of the range hood that is normally installed in the kitchen environment and faces the user; the first back panel 13 is a panel facing the wall and normally installed in the kitchen environment.

Referring to fig. 3 to 5, fig. 5 is a schematic structural diagram illustrating an exploded door panel 40 of the range hood, and in an embodiment, the first housing 10 further includes two side panels 14 disposed opposite to each other. The two side panels 14 are respectively connected to two sides of the first front panel 11. One side of the second air guiding plate 20 is provided with a gap, and is abutted against or connected with one side panel 14, and the other side of the second air guiding plate 20 is provided with a gap, is abutted against or connected with the other side panel 14. As a specific example, as shown in fig. 1 or 4, one side of the second air guiding plate 20 interferes with one side panel 14, and the other side of the second air guiding plate 20 interferes with the other side panel 14. In this way, the width (W shown in fig. 5) of the second air guiding plate 20 is long enough to guide the oil smoke entering the first casing 10 through the first air inlet 111, i.e. to have a better smoke guiding effect.

Referring to fig. 3 and 4, in an embodiment, one side of the bottom end of the first air guiding plate 30 is spaced from, abutted against or connected to one of the side panels 14, and the other side of the bottom end of the first air guiding plate 30 is spaced from, abutted against or connected to the other side panel 14. Referring to fig. 7, as a specific example, one side of the bottom end of the first wind guiding plate 30 is indirectly connected to one of the side panels 14 (indirect connection means that the two are not directly connected, but for example, a pushing mechanism 50 is further connected therebetween), and the other side of the bottom end of the first wind guiding plate 30 is indirectly connected to the other side panel 14 (indirect connection means that the two are not directly connected, but for example, a pushing mechanism 50 is further connected therebetween). Therefore, the distance between the bottom ends of the two first air deflectors 30 is large enough, so that the two first air deflectors 30 can guide the oil smoke in the first shell 10 to the first air outlet 121, and a good smoke guide effect is achieved.

Referring to fig. 3 and 4, in an embodiment, the second air guiding plate 20 is opposite to the first air inlet 111, and covers the first air inlet 111 in a projection of the first front panel 11. Therefore, the oil smoke entering the first housing 10 through the first air inlet 111 can be guided, i.e. the oil smoke guiding effect is good.

Referring to fig. 3 and 4, in an embodiment, the second air guiding plate 20 is located below the first air guiding plate 30, and a distance between the second air guiding plate 20 and the first back plate 13 gradually decreases from bottom to top. In this way, the second air guiding plate 20 is disposed obliquely relative to the first back panel 13, and can guide the oil smoke entering the first casing 10 through the first air inlet 111, that is, has a better smoke guiding effect.

Specifically, the second wind deflector 20 is any one or a combination of a straight plate, an arc plate and a folding plate. The setting is not limited herein, and may be set according to actual requirements.

Referring to fig. 3 and 8, fig. 8 is a schematic structural diagram illustrating the second air guiding plate 20 and the first air guiding plate 30 of the range hood of the embodiment are disposed on the first back panel 13. In one embodiment, the first air guiding plate 30 is provided with a first flange 31 near the side of the first front panel 11, and the first flange 31 is closely attached to the first front panel 11. The first air guiding plate 30 is provided with a second flange 32 on a side close to the first back plate 13, and the second flange 32 is tightly attached to the first back plate 13. Thus, the two first air deflectors 30 can guide the oil smoke in the first casing 10 to the first air outlet 121, i.e. have a better smoke guiding effect.

It should be noted that the "first flange 31 and the second flange 32" may be a part of the first air deflector 30, that is, the "first flange 31, the second flange 32" and the "other part of the first air deflector 30" are integrally formed; or the first flange 31 and the second flange 32 may be manufactured separately from the other parts of the first wind deflector 30, and then combined with the other parts of the first wind deflector 30 to form a whole. As shown in fig. 8, in an embodiment, the first flange 31 and the second flange 32 are integrally formed as a part of the first air guiding plate 30.

Referring to fig. 5 to 7, in an embodiment, the range hood further includes a door panel 40 movably disposed on the first front plate 11, and a pushing mechanism 50 connected to the door panel 40. The pushing mechanism 50 is used for driving the door panel 40 to move relative to the first front panel 11, so that the door panel 40 opens or closes the first air inlet 111. Thus, when the range hood works, the pushing mechanism 50 drives the door panel 40 to move to open the first air inlet 111 (as shown in fig. 1 and 3, the first air inlet 111 is in an open state), and the range hood normally discharges smoke; when the range hood is stopped, the pushing mechanism 50 drives the door panel 40 to move to close the first air inlet 111 (as shown in fig. 6 and 7, the first air inlet 111 is in a closed state), so that the oil smoke in the common flue can be prevented from flowing backwards and being discharged outwards through the first air inlet 111.

Referring to fig. 3, specifically, the bottom end of the first air guiding plate 30 is installed at a non-driving portion of the pushing mechanism 50. Of course, the bottom end of the first air guiding plate 30 may also be installed at other positions inside the first casing 10 according to actual requirements, for example, directly installed on the side wall of the first casing 10, and the like, which are not limited herein, and may be installed according to actual requirements. As an example, when the range hood is not provided with the door panel 40 and the pushing mechanism 50, the bottom end of the first air guiding plate 30 may be directly mounted on the sidewall of the first casing 10.

Referring to fig. 5 to 7, in an embodiment, the pushing mechanism 50 is disposed inside the first housing 10, a bracket 60 is connected to a pushing end of the pushing mechanism 50, and the bracket 60 is connected to the door 40. Thus, the door panel 40 is mounted on the bracket 60, and the mounting effect is stable. In addition, in order to avoid the support 60 to hinder the flue gas in the flue gas channel, a hollow-out opening is arranged on the support 60, so that the flue gas can smoothly pass through the support 60. In addition, it should be noted that the arrangement mode of the bracket 60 in the flue gas channel can be determined according to actual requirements, as long as the flow of the flue gas in the flue gas channel is not affected, and the bracket does not physically interfere with the two first air deflectors 30 and the second air deflector 20. For example, the bracket 60 may be movably disposed in an area between the second wind deflector 20 and the two first wind deflectors 30.

Of course, as an alternative, the pushing end of the pushing mechanism 50 may also be directly connected to the door panel 40, and is not limited herein.

In one embodiment, the pushing mechanism 50 includes, but is not limited to, an electric push rod, a motor pulley drive, a motor gear drive, or a motor screw drive, or an air cylinder. For example, when the pushing mechanism 50 is an electric push rod, a motor belt drive mechanism, a motor gear drive mechanism, or a motor screw drive mechanism, the non-driving portion refers to all portions other than the driving shaft on the motor; for another example, when the pushing mechanism 50 is a cylinder, the non-driving portion refers to all portions other than the piston on the cylinder.

Referring to fig. 3 and 7, in one embodiment, the first housing 10 is provided with guide rails 70 at opposite sides thereof, and the bracket 60 is movably disposed on the guide rails 70. Therefore, in the process that the pushing mechanism 50 pushes the bracket 60 to move, the operation effect of the bracket 60 and the door panel 40 is relatively stable under the guiding effect of the guide rail 70.

Referring to fig. 3 and 7, specifically, two pushing mechanisms 50 are provided, the two pushing mechanisms 50 are respectively located at two opposite sides in the first housing 10, and both pushing mechanisms 50 are connected to the bracket 60. In this manner, the carriage 60 can stably run along the guide rail 70 under the common driving action of the two pushing mechanisms 50. Of course, the pushing mechanism 50 may be one or another number, and is not limited herein.

Referring to fig. 3 and 7, in an embodiment, at least one limiting block 15 is disposed on an inner wall of the first casing 10, and the limiting block 15 is configured to be in interference fit with the bracket 60. When the pushing mechanism 50 drives the door panel 40 to move to the position of completely opening the first air inlet 111, the limiting block 15 abuts against the bracket 60 to limit the bracket 60 from moving further. In addition, when the pushing mechanism 50 drives the door panel 40 to move to a position of completely closing the first air inlet 111, the bracket 60 abuts against the second air guiding plate 20, and the second air guiding plate 20 restricts the bracket 60 from moving further.

Referring to fig. 2 to 4, in one embodiment, the range hood further includes a second housing 80 and a suction fan (not shown). The second housing 80 is disposed on the first top panel 12, the second housing 80 is provided with a second air inlet 81 and a second air outlet 82, the second air inlet 81 is in butt joint with the first air outlet 121, and the second air outlet 82 is used for communicating with a common flue (not shown). The exhaust fan is installed in the second housing 80 for providing power to discharge the oil smoke in the second housing 80 through the second air outlet 82. Thus, under the power action of the exhaust fan, the oil smoke in the first casing 10 enters the second casing 80 through the first air outlet 121, and is discharged to the outside through the second air outlet 82 of the second casing 80.

Further, a wind cabinet is provided inside the second casing 80. The exhaust fan is installed in the interior of the wind cabinet, and the second air inlet 81 is penetrated through and fixed on the inner wall of the wind cabinet at the top end of the first air deflector 30. So, the wind cabinet inner wall has great installation space, can guarantee that the board top can install more stably, simultaneously, adorns at the wind cabinet inner wall, can guarantee that the flue gas does not outwards reveal.

In one embodiment, the second housing 80 is removably connected to the first housing 10.

Referring to fig. 6 and 7, in an embodiment, a connecting pipe 83 is disposed at the second air outlet 82, a stop valve 84 is disposed on the connecting pipe 83, and the connecting pipe 83 is used for communicating with the common flue.

Referring to fig. 1, 3 and 4, in an embodiment, the range hood further includes an oil cup 90 disposed below the first housing 10. The oil cup 90 and the bottom end of the second air deflector 20 are provided with a gap 91. Therefore, the oil stains on the first front panel 11 and the second air deflector 20 can flow into the oil cup 90 through the gap 91, and the oil cup 90 can store the oil stains, so that the oil stains are prevented from falling into the external environment to cause pollution.
