Generally, a wind cabinet assembly of a range hood is fixed on a machine body, an air inlet is arranged on the front side of the machine body, and the range hood sucks oil smoke in a kitchen space into the machine body through the air inlet when in work. In addition, since assembly errors inevitably result in the existence of a ventilation gap in the body, for example, a connection portion between the top panel and the side panel of the body is provided with a ventilation gap, or a connection portion between the top panel and the front panel of the body is provided with a ventilation gap, or a position where the connection case is mounted on the top panel of the body is provided with a ventilation gap. When the fan subassembly is at the smoking in-process, on the one hand, the oil smoke in kitchen space passes through the air intake and from the side of intaking that up inhales the fan subassembly down, still through the ventilation gap from the side of intaking that down inhales the fan subassembly, so the oil smoke can produce the turbulent flow in the side of intaking of fan subassembly, and then greatly influenced the smoking effect.

Referring to fig. 1 to 3 and 5, fig. 1 shows a perspective structure schematic diagram of a range hood according to an embodiment of the present invention, fig. 2 shows a perspective structure schematic diagram of a decorative panel 60, a front panel 11, an air intake net 70, a wind shield 20 and a smoke shield 40 in fig. 1, fig. 3 shows a perspective structure schematic diagram of a top panel 12 and a back panel 13 in fig. 1, and fig. 5 shows a cross-sectional structure schematic diagram of a range hood according to an embodiment of the present invention. An embodiment of the present invention provides a range hood, including: fuselage 10, wind shield 20 and wind cabinet 30. The body 10 is provided with a smoke collecting chamber 101 therein, and the body 10 includes a front panel 11 and a top panel 12 connected to the front panel 11. The bottom of the front panel 11 is provided with an air inlet 111, and the top panel 12 is provided with an air outlet 121. The wind deflector 20 is disposed in the smoke collection cavity 101, and the smoke collection cavity 101 is divided into a first chamber 102 and a second chamber 103 which are isolated from each other by the wind deflector 20. The first chamber 102 is located below the second chamber 103, and the first chamber 102 communicates with the external environment of the fuselage 10 through an air inlet 111. The second chamber 103 is adapted to communicate with a common flue (not shown) via an outlet opening 121. The wind cabinet 30 is disposed in the first chamber 102, and the wind cabinet 30 is provided with a wind outlet end 31. The wind guard 20 is provided with a through opening 21, and the wind outlet end 31 extends into the second chamber 103 through the through opening 21 and is opposite to the wind outlet 121.

When the range hood described above works, the wind cabinet 30 provides a suction force so that the oil smoke in the kitchen space enters the first chamber 102 through the wind inlet 111, then enters the wind inlet side 32 of the wind cabinet 30, and is discharged to the public flue through the wind outlet end 31 and the wind outlet 121 of the wind cabinet 30. When the range hood is in normal use, air in the second chamber 103 is blocked by the wind shield 20 and cannot enter the first chamber 102, namely, turbulence can not be generated with inlet air entering the air inlet side 32 of the air cabinet 30 from the air inlet 111, so that the smoke suction mode of the air cabinet 30 intensively sucks oil smoke entering from the air inlet 111, the smoke suction effect of the range hood is optimized, the working frequency of the air cabinet 30 can be correspondingly reduced, the noise of a fan is reduced to a certain extent, and energy is saved.

Referring to fig. 4 to 6, fig. 4 is a schematic view illustrating a wind deflector 20 of a range hood according to an embodiment of the present invention, and fig. 6 is an enlarged schematic view of a portion a of fig. 5. Further, one end of the wind deflector 20 is provided with a first bent plate 22, and the plate surface of the first bent plate 22 is overlapped and connected with one end of the top panel 12 close to the front panel 11.

Referring to fig. 4, 5 and 7, fig. 7 is an enlarged schematic view of fig. 5 at B. Further, the body 10 includes a back panel 13 spaced opposite the front panel 11, and two side panels 14 spaced opposite each other. The back panel 13 is connected to the top panel 12 and the two side panels 14, respectively. The other end of the wind deflector 20 is provided with a second bent plate 23. The second bent plate 23 is connected to the top of the back plate 13 in an overlapping manner, and two opposite side edges of the wind deflector 20 are respectively in tight interference fit with the inner surfaces of the two side panels 14.

Referring to FIGS. 6 and 7, in one embodiment, the first bending plate 22 is detachably connected to the top plate 12 by a first fastening member 24. The plate surface of second bent plate 23 is detachably connected to back plate 13 by second fastening member 25. Therefore, the air deflector can be conveniently detached or installed on the inner wall of the machine body 10, and meanwhile, the sealing performance of the connecting part of the air deflector and the inner wall of the machine body 10 can be ensured.

Specifically, the first fastening member 24 and the second fastening member 25 are, for example, screws, bolts, pins, rivets, clips, and the like, and are not limited herein and may be provided according to actual situations. In addition, the first bending plate 22 and the second bending plate 23 are not limited to being mounted on the body 10 by fasteners, but may alternatively be fixedly mounted on the body 10 by welding, bonding, or the like.

It should be noted that the "first bending plate 22" and the "second bending plate 23" may be a part of the "wind deflector 20", that is, the "first bending plate 22" and the "second bending plate 23" are integrally formed with the "other part of the wind deflector 20"; or a separate member which is separable from the rest of the wind deflector 20, i.e., the first bent plate 22 and the second bent plate 23 may be separately manufactured and then combined with the rest of the wind deflector 20 to form a single body. As shown in fig. 4, in one embodiment, the "first bent plate 22" and the "second bent plate 23" are integrally formed as a part of the "wind deflector 20".

Referring to fig. 2, 5 and 8, fig. 8 is an enlarged schematic view of fig. 5 at C. In one embodiment, the range hood further includes a smoke barrier 40. The smoke barrier 40 is installed on the body 10 and is disposed to overlap the front panel 11, and the smoke barrier 40 is used to isolate the front panel 11 from the smoke collection chamber 101. The inlet side 32 of the hood 30 is spaced from the smoke barrier 40 to form an inlet air channel 104. Therefore, on one hand, the smoke baffle 40 can separate the front panel 11 and the electrical components 50 arranged on the front panel from the smoke collection cavity 101, so that the oil smoke sucked by the range hood during operation can not invade the electrical components 50 to cause the failure of the electrical components 50, and the core parts can be prevented from being damaged; on the other hand, because the smoke baffle 40 is disposed inside the smoke collection cavity 101 and located right in front of the wind cabinet 30, the wind cabinet 30 and the smoke baffle 40 enclose to form a narrow air intake channel 104, according to bernoulli's principle, when the fluid flows in the channel, the cross-sectional area through which the fluid passes is smaller under the condition of the same flow rate, the flow rate is larger, and thus the oil and smoke absorption effect of the range hood is more significant.

Referring to fig. 2, 5 and 8, in one embodiment, an electrical component 50 is disposed on the front panel 11. The electrical component 50 is at least one of a control switch, a lighting spotlight and a circuit control board.

It is understood that the electrical component 50 may also be other core components disposed on the front panel 11, and is disposed according to actual requirements, and is not limited herein.

Referring to fig. 2, fig. 5 and fig. 8, further, two electrical components 50 are illustrated in fig. 2 and fig. 5, wherein one electrical component 50 is a control switch, and the other electrical component 50 is an illumination spot lamp. Accordingly, the front panel 11 is provided with an installation opening 113 corresponding to the size of the electrical component 50, and the electrical component 50 is provided in the installation opening 113.

Further, the range hood further comprises a decorative panel 60. The decorative panel 60 is superposed on the front panel 11. The front panel 11 is provided with a smoke blocking surface 112 adjacent to the air inlet 111. The decorative panel 60 is provided with a protruding portion 61 protruding to an area below the smoke stop surface 112, and the protruding portion 61 is disposed opposite to an upper area of the air inlet 111. Thus, because the smoke blocking surface 112 and the protruding part 61 play a role in blocking rising oil smoke, when the rising oil smoke touches the smoke blocking surface 112 of the front panel 11 arranged above the air inlet 111, the rising oil smoke is blocked and scattered by the smoke blocking surface 112 of the front panel 11, so that the oil smoke cannot continue to rise, and meanwhile, the protruding part 61 of the decoration panel 60 can effectively prevent the oil smoke from diffusing outwards, thereby ensuring that the smoke machine can completely suck the residual oil smoke into the machine body 10, preventing the oil smoke from being on the face, and protecting the physical and psychological health of a cooker; in addition, the underneath air inlet 111 bends the smoke channel inside the range hood, thereby improving the oil-fat separation degree of the range hood.

It should be noted that the "protrusion 61" may be "a part of the decorative panel 60", that is, the "protrusion 61" and "the other part of the decorative panel 60" are integrally formed; the "projection 61" may be manufactured separately and integrated with the "other portion of the trim panel 60" as a single unit. As shown in fig. 5 and 8, in one embodiment, the "protrusion 61" is a part of the "decorative panel 60" that is integrally formed.

The decorative panel 60 is fixed to the front panel 11 by means of a fixing member such as a bolt, a screw, a pin, a rivet, a clip, or the like, and may be fixed to the front panel 11 by means of bonding, welding, or the like.

Referring to fig. 2, 5 and 8, in one embodiment, the smoke barrier 40 has at least one annular protrusion 42 or annular recess 41 on the surface. Thus, when the smoke baffle 40 is arranged at the position right in front of the wind cabinet 30 in the smoke machine, the noise generated in the wind cabinet 30 during the work of the smoke machine can be effectively separated and rebounded, so that the noise is reduced when a user cooks the smoke machine.

Referring to fig. 2, a plurality of protrusions 42 or recesses 41 are provided, and a plurality of protrusions 42 or recesses 41 are sequentially nested from the central portion to the peripheral portion of the surface of the smoke barrier 40. Therefore, the noise generated in the wind cabinet 30 can be effectively isolated and rebounded when the range hood works. Specifically, the concave portion 41 or the concave portion 41 is obtained by pressing the plate surface of the smoke barrier 40. In addition, the specific shape of the convex portion 42 or the concave portion 41 is, for example, a zigzag shape, a circular ring shape, an elliptical ring shape, or the like, and is not limited herein, and may be set according to the actual situation.

Generally speaking, there is a period of time from the generation of the oil smoke to the inhalation of the range hood, and if the oil smoke cannot be completely inhaled by the wind cabinet 30 in this period of time, the scattered oil smoke will generate a vortex flow inside the machine body, and thus the vortex flow is diffused to the outside of the machine body 10, which affects the use of the cooker.

Referring to fig. 2, 5 and 8, in one embodiment, the distance d between the air inlet side 32 of the wind cabinet 30 and the surface of the smoke barrier 40 is 10mm to 60 mm. As an example, the spacing d is specifically 10mm, 20mm, 30mm, 40m, 50mm and 60 mm. Therefore, the air inlet channel 104 is narrow, the flow speed of the oil smoke sucked by the range hood is increased when the oil smoke passes through the air inlet channel 104, and the oil smoke can reach the inside of the air cabinet 30 and be discharged to the public flue more quickly, so that the oil and smoke suction effect of the range hood is greatly improved. Of course, the distance d is not limited to be in the range of 10mm-60mm, and may be other values, and is not limited herein.

Referring to fig. 2 and 3, in an embodiment, the body 10 further includes a connecting shell 15 disposed at the air outlet 121. The connection housing 15 is adapted to communicate with a common flue. In this way, the soot in the body 10 is smoothly communicated to the common flue through the connection housing 15. Specifically, the connecting shell 15 is a shroud disposed circumferentially around the air outlet 121. Furthermore, a check valve is provided on the connection housing 15. Thus, when the wind cabinet 30 is in operation, the wind cabinet 30 sucks the oil smoke in the kitchen space into the body 10 through the wind inlet 111, and sends the oil smoke out to the common flue through the wind outlet 121 via the connecting shell 15 and the check valve. When the wind cabinet 30 stops working, the check valve can prevent the oil smoke in the common flue from entering the machine body 10 through the connection shell 15, thereby preventing the oil smoke in the common flue from flowing backward into the kitchen space.

Referring to fig. 1 to 3, in an embodiment, the range hood further includes an air inlet net 70 disposed at the air inlet 111. The net surface of the air inlet net 70 is provided with filter holes 71. Therefore, when the range hood works, in the process that oil smoke in a kitchen is sucked into the machine body 10 through the air inlet 111, the filtering holes 71 of the air inlet net 70 can filter the oil smoke, and large-particle impurities are prevented from being sucked into the machine body 10 to damage the fan. The shape of the filter holes 71 may be, for example, a strip-shaped hole, a square-shaped hole, a circular hole, an elliptical hole, etc., and is not limited herein and may be set according to actual conditions. Optionally, the net surface of the air inlet net 70 is a concave surface recessed toward the inside of the body 10. Therefore, the air inlet net 70 with the net surface concave inwards can improve the smoke collecting effect at the air inlet 111.

Referring to fig. 1 to 3, the range hood further includes an oil receiving cup assembly 80 disposed at the bottom of the body 10. The oil cup assembly 80 is used to receive oil droplets that fall down the front of the fuselage 10.

The back panel 13, the top panel 12 and the two side panels 14 may be integrally formed, that is, manufactured by integral molding, or welded to form an integral structure; it may of course be separate and independent components which are then assembled together using bolts, screws, pins, rivets, clips, etc.

Referring to fig. 2, further, in order to facilitate the installation of the smoke barrier 40, flanges 16 are provided on both the side panels 14 and the top panel 12. Three sides of the smoke barrier 40 are detachably connected with the flanges 16 of the two side panels 14 and the top panel 12 respectively through mounting members (not shown). In addition, the other side edge of the smoke baffle 40 is detachably connected with one side edge of the air inlet net 70 through a mounting piece, and the other three side edges of the air inlet net 70 are respectively and correspondingly detachably connected with the flanges 16 of the two side panels 14 and the bottom edge 131 of the back panel 13 through the mounting piece.

Referring to fig. 1 to 3, in one embodiment, the front panel 11 extends from one side of the body 10 to the other side of the body 10. Further, the projecting portion 61 of the decorative panel 60 extends from one of the side surfaces of the body 10 to the other side surface of the body 10. Therefore, the protruding part 61 of the decoration panel 60 can effectively prevent the oil smoke from diffusing outwards, so that the smoke machine can be ensured to completely suck the residual oil smoke into the machine body 10, the oil smoke does not face the face, and the physical and psychological health of a cooker is protected.

Referring to fig. 8, further, when the extractor hood is installed on a wall surface of a kitchen, a distance between a height of a bottommost edge of the protruding portion 61 with respect to the ground and a height of a bottommost edge of the smoke blocking surface 112 with respect to the ground is S (not shown), and S is within 0.2 mm. Specifically, S is 0mm, 0.1mm and 0.2 mm. Therefore, on one hand, a better cigarette gathering effect can be realized, and the oil smoke is prevented from being on the face; on the other hand, the oil smoke will not enter the interior of the body 10 through the air inlet 111.

The height of the bottommost edge of the protruding portion 61 with respect to the ground may be higher than the height of the bottommost edge of the smoke stop surface 112 with respect to the ground, or may be lower than the height of the bottommost edge of the smoke stop surface 112 with respect to the ground. It should be further noted that, the wall surface mentioned in the present embodiment refers to a wall body arranged along the vertical direction F (as shown in fig. 8).

Referring to FIG. 8, in one embodiment, the distance between the bottommost edge of the protrusion 61 and the topmost edge of the smoke stop surface 112 is L (as shown in FIG. 8), which is 10mm to 40 mm. In this embodiment, L is, for example, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, and 40 mm. Therefore, the size of the protruding part 61 is designed reasonably, on one hand, the size of the protruding part 61 is not too small, a good cigarette gathering effect can be achieved, and oil smoke is prevented from getting on the face; on the other hand, the protrusion 61 is not too large, i.e. the oil smoke is not prevented from entering the inside of the body 10 through the air inlet 111.

Referring to fig. 8, in an embodiment, when the range hood is installed on a wall surface of a kitchen, an inclination angle of the mouth surface of the air inlet 111 with respect to the vertical direction F is a1, an inclination angle of the smoke blocking surface 112 with respect to the vertical direction F is a2, and an inclination angle of the panel surface of the decoration panel 60 with respect to the vertical direction F is a 3. Wherein a1 is 50-70 degrees, a2 is 70-80 degrees, and a3 is 20-40 degrees.

It should be noted that the front side of the body 10 refers to a surface of the body 10 facing a user when the range hood is installed in a kitchen space. The back of the body 10 means that the surface of the body 10 facing the wall, that is, the surface opposite to the front of the body 10, after the range hood is installed in the kitchen space. The top surface of the body 10 refers to a surface of the body 10 away from the ground after the range hood is installed in the kitchen space. The side of the body 10 refers to a surface of the body 10 located on both sides of the front surface of the body 10 or the back surface of the body 10.

It should be noted that the external environment of the body 10 is the installation environment of the range hood, specifically, for example, the environment of a kitchen space.

It should be noted that while one of the elements is described as being connected to another element and one of the elements is described as being attached to another element, it should be understood that the two elements may be connected by, for example, bolts, screws, pins, rivets, or other mounting means, or may be fixedly connected by snapping, welding, or integral molding. Wherein, the integrated molding mode can adopt the processes of extrusion, casting, press fitting, injection molding and the like.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
