DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] This embodiment discloses the following features. The first feature is that the device is equipped with an air flow guide surface, an air collection section having an opening formed in the air flow guide surface, and a blower that draws in air through the opening and forcibly exhausts it to the outside, and electrical equipment is arranged along the air flow guide surface with a gap between them (see Figures 9, 10, 11, etc.). This configuration allows electrical equipment to be installed along the airflow guide surface without impairing suction performance, which eliminates the need to secure a large amount of space around the airflow guide surface for installing electrical equipment, thereby reducing design restrictions when designing the range hood.

[0009] The second feature is that an electrical equipment mounting section is fixed to the air flow guide surface, and the electrical equipment is mounted on this electrical equipment mounting section (see Figs. 9, 10, 11, etc.). According to this configuration, the electrical equipment mounting portion can improve the appearance.

[0010] A third feature is that the electrical equipment mounting section is an airflow adjusting section that adjusts the flow of gas toward the opening (see FIG. 9). According to this configuration, the flow of gas can be adjusted by the electrical equipment mounting section.

[0011] The fourth feature is that, in addition to the airflow adjustment section, a movable straightening plate is provided, which is arranged with a gap between it and the airflow guide surface and forms an intake port between it and the airflow guide surface (see Figures 1 and 3, etc.). According to this configuration, the airflow can be adjusted by the airflow straightening plate.

[0012] As a fifth feature, the airflow adjustment portion and the current plate are arranged side by side so that their surfaces are flush with each other (see Figs. 9, 10, 11, etc.). With this configuration, the flow of gas along the surfaces of the air flow adjustment section and the straightening plate can be regulated, and thus the gas can be efficiently sucked between the gas adjustment section and the straightening plate and the air flow guide surface.

[0013] As a sixth feature, the airflow adjustment portion and the current plate are in contact with each other along a line or a surface (see Figs. 9, 10, 11, 12, etc.). According to this configuration, the appearance of the connection portion between the air flow adjustment portion and the straightening plate can be improved.

[0014] As a seventh feature, a gap capable of sucking in gas is provided between the airflow adjustment portion and the straightening plate (see FIG. 13). According to this configuration, gas can be sucked in through the gap between the airflow adjustment portion and the flow straightening plate.

[0015] As an eighth feature, the current plate is formed larger than the airflow adjustment portion (see Figs. 1 and 2, etc.). This configuration can improve the cleaning performance.

[0016] <First embodiment> Next, specific embodiments having the above-mentioned features will be described in detail with reference to the drawings. The range hood 1 comprises an air collection section 10 that guides gas flowing along an air flow guide surface 11 to an opening 12 formed in the air flow guide surface 11, an air flow adjustment section 20 that adjusts the flow of gas toward the opening 12, a straightening plate 30 that is arranged with a gap between it and the air flow guide surface 11 and separate from the air flow adjustment section 20 and forms an intake port 10a between it and the air flow guide surface 11, a housing 40 that covers the gas flow path from the opening 12 to an exhaust port 40b1, and a blower 50 that is provided in the gas flow path and forcibly exhausts gas sucked in from the opening 12 to the outside through the exhaust port 40b1.

[0017] The air collection section 10 is provided with a generally concave air flow guide surface 11 that opens obliquely downward and has a bottom 11a, and an opening 12 is formed on the central side of this air flow guide surface 11. This air collection section 10 is sometimes referred to as a hood section.

[0018] The air flow guide surface 11 is integrally formed of an inclined flat bottom portion 11a, an upper piece portion 11b bent forward at the upper end side of the bottom portion 11a, and a lower piece portion 11c bent downward at the lower end side of the bottom portion 11a. An oil drain plate introduction port 11c1 for inserting an oil drain plate 37 (described later) is opened in a horizontally elongated rectangular shape and penetrates the lower piece 11c.

[0019] This air flow guide surface 11 guides the air flowing in from the left, right and upper suction ports 10a to an opening 12 near the center of the bottom 11a.

[0020] The opening 12 is a circular through-hole provided near the center of the bottom 11a, and sucks in the air that flows along the air flow guide surface 11 and is guided toward the center of the air flow guide surface 11. The inner edge of this opening 12 curves toward the inside of the housing 40 .

[0021] An oil collecting device 70 (see FIG. 3) that collects oil by rotating a disk-shaped filter is provided in a position close to the inner edge of the opening 12 inside the housing 40. This oil collecting device 70 can be replaced with one having a different structure or can be omitted.

[0022] The airflow adjustment unit 20 is a hollow box-shaped member that is long in the left-right direction and is positioned approximately parallel to and spaced from the upper part of the bottom 11a. One and the other longitudinal ends of the airflow adjustment unit 20 are fixed to the bottom 11a via brackets 21 that are approximately pillar-shaped.

[0023] The gap between the upper end edge of the airflow adjustment section 20 and the bottom 11a, the gap between the left end edges of the airflow adjustment section 20 and the straightening plate 30 and the bottom 11a, and the gap between the right end edges of the airflow adjustment section 20 and the straightening plate 30 and the bottom 11a each function as an intake port 10a for drawing in external gas.

[0024] The distance between the airflow adjustment portion 20 and the bottom portion 11a is appropriately adjusted so as to accelerate the gas sucked into the suction port 10a.

[0025] The rear surface of airflow adjustment unit 20 has protruding portion 20a narrowing the distance between it and bottom portion 11a at the center in the left-right direction, and has recessed portions 20b, 20b on both left and right sides of protruding portion 20a that are recessed so as to widen the distance between it and bottom portion 11a. That is, the rear surface of airflow adjustment unit 20 is formed in a substantially convex shape having protruding portion 20a and recessed portions 20b, 20b on both sides (see FIG. 5).

[0026] Further, an inwardly inclined surface 20c is formed at the upper end of the airflow adjustment portion 20. This inclined surface 20c suppresses turbulence in the flow of gas that is sucked in between the bottom portion 11a and accelerated.

[0027] The airflow adjustment section 20 also functions as an electrical component mounting section for mounting electrical components such as a first illumination section 61 and an operation section 62 (see FIG. 9).

[0028] Further, the airflow adjustment section 20 and a straightening plate 30 described later function as a light blocking member that blocks the light emitted from the first illumination section 61 from being directly irradiated downwardly of the range hood 1.

[0029] The first illumination section 61 is an elongated light-emitting body that spans the width direction of the airflow adjustment section 20, and is configured, for example, by a plurality of LEDs.

[0030] The first illumination section 61 is attached to the rear surface side within the air flow adjustment section 20 so as to emit light between the air flow adjustment section 20 as a light blocking member and the air flow guide surface 11. More specifically, the first lighting unit 61 is fixed inside the air flow adjustment unit 20 via a bracket or the like, and its irradiation direction is inclined toward the upper air intake port 10a side. The light of the first lighting unit 61 is emitted from the back surface of the air flow adjustment unit 20 and illuminates the air flow guide surface 11 (see FIG. 9).

[0031] The airflow adjustment section 20 is provided with a first light-transmitting cover 63 that is light-transmitting and located on the side of the irradiation direction of the first illumination section 61. The first light-transmitting cover 63 is made of a light-transmitting plate-like member that is transparent, colored transparent, translucent, etc., and is formed into a long shape that spans the width of the airflow adjustment unit 20, and is fixed so that it is approximately flush with the back surface of the airflow adjustment unit 20 (see Figure 5). The material of the first light-transmitting cover 63 may be glass, a heat-resistant and flame-retardant synthetic resin material, or the like.

[0032] The first light-transmitting cover 63 can prevent oil, moisture, foreign matter, and the like from adhering to the first illumination section 61, and thus can reduce the occurrence of breakdowns in the first illumination section 61.

[0033] The operation unit 62 is composed of an electronic circuit 62a for turning the first illumination unit 61 on and off and adjusting the illuminance, a plurality of operation switches 62b, and the like. The electronic circuit 62 a is contained within the airflow adjustment unit 20 . The operation switch 62b is a capacitance type switch that is electrostatically turned on and off when the user's finger touches it so that the user can operate it from below. As another example of this operation switch 62b, it may be a pressure-sensitive switch that is exposed on the surface side of the airflow adjustment unit 20 and is operated by pressing it.

[0034] While the first lighting section 61 is an indirect light, the range hood 1 is also provided with a second lighting section 65 that directly illuminates the area below the range hood 1. The second illumination section 65 is attached to the rear side of the upper portion of the air flow guide surface 11 (in the illustrated example, the upper piece portion 11b) within the housing 40 via a bracket or the like (see FIG. 2). A second light-transmitting cover 66 is provided on the irradiation direction side of the second illumination unit 65 so as to be substantially flush with the upper piece portion 11b.

[0035] The second illumination section 65 and the second light-transmitting cover 66 are provided in an elongated shape along the width direction of the air flow guiding surface 11 . The materials and parts constituting the second illumination section 65 and the second light-transmitting cover 66 may be similar to those of the first illumination section 61 and the first light-transmitting cover 63 described above.

[0036] In addition, the straightening plate 30 is located below the airflow adjustment section 20 so as to be spaced apart from and follow the bottom 11a of the airflow guide surface 11, and is arranged side by side with the airflow adjustment section 20 so that their surfaces are flush with each other (see FIG. 1). The current plate 30 is a member having a generally rectangular plate shape in a plan view, and is formed to be longer in the inclined direction along the bottom 11a than the airflow adjustment unit 20. The surface area of ​​the current plate 30 in the direction along the bottom 11a is larger than the surface area of ​​the airflow adjustment unit 20 in the same direction.

[0037] The diagonally lower end face of the airflow adjustment section 20 is in face contact with the end face of the opposing straightening plate 30. In this way, in the range hood 1, a gap that could serve as an intake port is not formed between the airflow adjustment section 20 and the straightening plate 30, and the connecting portion between the airflow adjustment section 20 and the straightening plate 30 has a good appearance. As another example, the airflow adjustment portion 20 and the flow straightening plate 30 may be in contact with each other along a line.

[0038] On the back surface of this straightening plate 30, a wind speed adjusting protrusion 31 is provided which rises toward the air flow guide surface 11 side (specifically, the bottom portion 11a side) and has a narrower distance from the air flow guide surface 11. The current plate 30 is configured to rotate about a horizontal rotation axis 34a that is aligned with the airflow guide surface 11, and the wind speed adjusting protrusion 31 is disposed on the centrifugal direction side of the rotation axis 34a.

[0039] The wind speed adjusting convex portion 31 protrudes in a convex shape from the central portion of the rectifying plate 30 toward the air flow guide surface 11 relative to the peripheral edge side, and the tip surface is formed into a flat surface that fits along the air flow guide surface 11. The protruding height of this wind speed adjusting convex portion 31 is substantially the same as the protruding height of the convex portion 20a of the airflow adjusting portion 20 according to the illustrated example.

[0040] An inclined surface 31a inclined inwardly toward the tip surface is provided on the peripheral edge of the wind speed adjusting protrusion 31. In the illustrated example, this inclined surface 31a is formed by forming the side surface of the wind speed adjusting protrusion 31 into a flat surface inclined inwardly toward the tip of the wind speed adjusting protrusion 31. This inclined surface 31a suppresses turbulence in the airflow flowing from the side toward the inside of the suction port 10a.

[0041] Moreover, the wind speed adjusting protrusion 31 is provided so as to include at least a part of the opening 12 and at least a part of the air flow guide surface 11 (more specifically, the bottom portion 11a) around the opening 12 when viewed from the direction facing the opening 12. In other words, the wind speed adjusting protrusion 31 is provided so as to overlap at least a part of the opening 12 and at least a part of the air flow guide surface 11 around the opening 12 when viewed from the direction facing the opening 12. In particular, according to a preferred example of the present embodiment, the wind speed adjusting convex portion 31 is disposed so as to include the entire opening 12 when viewed from the direction facing the opening 12 (see FIG. 4). According to this arrangement, the gas sucked into the opening 12 can be accelerated evenly and efficiently around the entire circumference of the opening 12 .

[0042] At least a part of the peripheral side of the back surface of the straightening plate 30 is provided with a corner-side lower surface portion 32 that rises lower than the tip surface of the wind speed adjusting protrusion 31 toward the airflow guide surface 11 (see FIG. 3). As another example, it is also possible to configure the corner-side lower surface portion 32 not to rise. According to the illustrated example, the corner-side lower surface portions 32 are provided at two corners on the upper side (in other words, on the centrifugal direction side centered on the rotation axis 34a) of the straightening vane 30. Each corner-side lower surface portion 32 is formed in a flat surface shape lower than the tip of the wind speed adjusting protrusion 31.

[0043] A movement operation unit 35 for manually rotating and moving the straightening plate 30 is provided on each of the two corner lower surface portions 32, 32. The movement operation portion 35 in the illustrated example includes a bracket 35a rising from the corner-side lower surface portion 32, and a screw-like member 35b rotatably inserted into the bracket 35a. The screw-shaped member 35b is inserted into the bracket 35a with the threaded portion facing inward (toward the wind speed adjusting protrusion 31 side). The threaded portion is screwed into a screwed member 36 (see FIG. 3) protruding from the bottom portion 11a.

[0044] As other examples of the moving operation unit 35, it is possible to apply structures other than those shown in the figures, such as a configuration in which the moving operation unit 35 is engaged and disengaged from the air flow guide surface 11 by operating a push button or other operations, or a configuration in which the moving operation unit 35 is attached and detached to the air flow guide surface 11 by operating a push button or other operations.

[0045] The rectifying plate 30 has a peripheral portion made up of a plurality of sides, and at least one of the plurality of sides is provided with a side lower surface portion 33 that does not rise toward the air flow guide surface 11 (see FIG. 3). According to the illustrated example, the side low surface portion 33 is continuous around the entire periphery of the edge of the side low surface portion 33. The side low surface portion 33 is formed in a flat surface that is lower than the tip of the wind speed adjusting convex portion 31 and lower than the corner side low surface portion 32. As other examples, the side low surface portion 33 may be flush with the corner side low surface portion 32, or the side low surface portion 33 may be lower than the tip of the wind speed adjusting convex portion 31 and higher than the corner side low surface portion 32.

[0046] Of these side-side lower surface portions 33, the side-side lower surface portions 33 corresponding to the lower sides of the straightening plate 30 have hinges 34 attached to both the left and right sides (see FIG. 6). The hinges 34 have one piece that rotates about a rotation shaft 34a as a fulcrum attached to the side-side lower surface portion 33, and the other piece that is attached to the air flow guide surface 11.

[0047] In the illustrated example, the shape of the rear surface of the straightening plate 30 from the left and right side lower surfaces 33, 33 to the wind speed adjustment convex portion 31 is approximately the same as the shape of the rear surface of the airflow adjustment portion 20 from the recesses 20b, 20b on both sides to the convex portion 20a (see Figures 5 and 6).

[0048] In addition, an oil drain plate 37 is connected to the lower end side of the current plate 30. The oil drain plate 37 is formed in a curved shape extending from the lower end side of the straightening plate 30 toward the inside of the oil drain plate inlet 11c1 on the lower side of the air flow guide surface 11. Oil, moisture, etc. adhering to the back side of the straightening plate 30 flows down the oil drain plate 37 to the back side of the air flow guide surface 11 and is stored in a recessed oil reservoir 41 provided on the lower end side of the housing 40.

[0049] In addition, the housing 40 has therein an intake chamber 40a located on the back side of the airflow guide surface 11 and a blower chamber 40b communicating with the upper part of the intake chamber 40a. The gas sucked in from the opening 12 passes through the intake chamber 40a and the blower chamber 40b and is exhausted from the exhaust port 40b1 on the upper end side.

[0050] In the illustrated example, the suction chamber 40a is formed in a horizontal triangular prism shape, and the front, rear, left, right, and top surfaces are covered by multiple panels. Of these panels, the surface of the panel exposed to the front surface constitutes the airflow guide surface 11. An opening (not shown) is provided in the top panel 40a1, and the panel constituting the blower chamber 40b is connected to communicate with this opening.

[0051] The suction chamber 40a is provided with the above-mentioned oil collecting device 70. The gas that is sucked into the opening 12 and passes through the oil collecting device 70 is guided to the blower chamber 40b.

[0052] The front, rear, left, right and top of the fan chamber 40b are covered with panels. A cylindrical exhaust port 40b1 is connected to the upper end of each of these panels so as to communicate with the inside of the fan chamber 40b.

[0053] A blower 50 is provided in the blower chamber 40b. In the illustrated example, the blower 50 is a sirocco fan, which draws in air from the front and expels it to the upper exhaust port 40b1. As another example of the blower 50, a blower other than the above, such as a propeller fan, can be used.

[0054] Next, the characteristic functions and effects of the range hood 1 having the above configuration will be described in detail. When power is supplied to the range hood 1 and the blower 50 rotates, the range hood 1 generates an airflow that flows from the air inlet 10a through the opening 12 toward the air outlet 40b1. More specifically, gas (eg, air, smoke, etc.) from the left, right and upper suction ports 10 a passes between the airflow adjustment portion 20 , the straightening plate 30 and the airflow guide surface 11 and is guided to the opening 12 . At this time, the gas is rapidly accelerated as it passes through the gap narrowed by the wind speed adjusting convex portion 31 of the straightening vane 30 and the convex portion 20a of the airflow adjusting portion 20. Therefore, the gas around the range hood 1 is sucked into the suction port 10a and efficiently guided to the opening 12. Then, the gas that has entered the opening 12 passes through the suction chamber 40a and the blower chamber 40b in the housing 40 and is forcibly exhausted from the exhaust port 40b1.

[0055] In the illustrated example, the protruding height of the wind speed adjusting convex portion 31 of the straightening plate 30 and the protruding height of the convex portion 20a of the airflow adjusting portion 20 are made approximately the same, but it is possible to replace the airflow adjusting portion 20 with one having a convex portion 20a of a different height to adjust the speed of the gas sucked in from the upper suction port 10a.

[0056] Furthermore, according to the above embodiment, if dirt accumulates after long-term use, the user can loosen the screw-shaped member 35b, place their fingers in the recessed portions such as the corner side lower surface portion 32 and the edge side lower surface portion 33, and rotate the straightening plate 30 to open it, thereby easily cleaning the back side of the straightening plate 30 and the air flow guide surface 11.

[0057] Furthermore, when the operation switch 62b is operated to turn on the first illumination unit 61, part of the light emitted from the first illumination unit 61 passes through the first light-transmitting cover 63 and travels toward the air flow guide surface 11. Furthermore, this light is reflected by the air flow guide surface 11 and travels toward the outside of the air intake 10a (see FIG. 9). Incidentally, the light emitted from the first illumination section 61 and heading directly downward is blocked by the airflow adjustment section 20 and the airflow straightening plate 30 which serve as light blocking members.

[0058] Therefore, when the first lighting section 61 emits light, it is possible to obtain an appropriate brightness that is not too bright, and in turn, to improve the aesthetic appearance of the range hood 1. Moreover, since the airflow adjustment section 20 and the rectifying plate 30 function as light blocking members, it is possible to prevent users, etc. from looking directly at the first lighting section 61 and feeling dazzled.

[0059] Moreover, when it is desired to brighten a stove or the like below the range hood 1, the second illumination section 65 may be turned on.

[0060] Furthermore, according to the range hood 1 having the above-described configuration, since the airflow adjustment section 20 is used as an electrical equipment mounting section, there is no need to secure a large amount of space for mounting electrical equipment in the frame-shaped section around the air collection section 10 or the like. Therefore, design restrictions imposed on the range hood 1 can be reduced.

[0061] <Second embodiment> Next, other embodiments of the present invention will be described. Note that the embodiments described below are partial modifications of the range hood 1 having the above configuration, so the modifications will be mainly described in detail and overlapping detailed descriptions will be omitted.

[0062] In the range hood 2 shown in FIG. 10, electrical components such as a first lighting unit 61 and an operating unit 62 and a first light-transmitting cover 63 are not provided on the airflow adjustment unit 20 but on the airflow straightening plate 30.

[0063] In this range hood 2, the straightening plate 30 has a first lighting section 61 fixed thereto via a bracket or the like, and a first light-transmitting cover 63 is fixed on the irradiation direction side of the first lighting section 61 so as to be flush with the tip end face of the wind speed adjusting protrusion 31. The first lighting section 61 is fixed so as to illuminate the airflow guide surface 11 with its radiation direction inclined toward the upper air intake port 10a side. Furthermore, the rectifying plate 30 has an operation unit 62, which is composed of an electronic circuit 62a and an operation switch 62b, fixed therein, and the operation switch 62b is exposed on the surface side.

[0064] Therefore, according to the range hood 2 shown in Figure 10, similarly to the above-mentioned range hood 1, the light emitted from the first lighting section 61, which is indirect lighting, can improve the aesthetic appearance of the range hood 2, and can prevent users, etc. from looking directly at the first lighting section 61 and feeling dazzled. In addition, there is no need to secure a large amount of space for mounting electrical equipment in the frame-like portion surrounding the air collection section 10, which in turn reduces design restrictions when designing the range hood 1.

[0065] <Third embodiment> In the range hood 3 shown in FIG. 11, electrical components such as a first lighting unit 61 and an operating unit 62 and a first light-transmitting cover 63 are not provided on the airflow adjustment unit 20 and the straightening plate 30, but are attached to the airflow guide surface 11.

[0066] The airflow guide surface 11 of the range hood 3 has a first lighting section 61 fixed to the back side of the bottom 11a via a bracket or the like, and a first light-transmitting cover 63 fixed to the irradiation direction side of the first lighting section 61 so as to be flush with the surface of the bottom 11a. The first lighting section 61 is oriented so that its irradiation direction is inclined toward the upper air intake 10a side, toward the inner surface of the airflow adjustment section 20.

[0067] Therefore, the light of the first illumination unit 61 is emitted from the air flow guide surface 11 and illuminates the rear surface of the air flow adjustment unit 20 serving as a light blocking member. Then, a part of the light reflected by the rear surface of the air flow adjustment unit 20 leaks to the outside through the suction port 10a.

[0068] In addition, an operating section 62 consisting of an electronic circuit 62a and an operating switch 62b etc. is fixed to the rear side of the airflow guide surface 11, which is located above the airflow adjustment section 20, and the operating switch 62b is exposed on the front side. Incidentally, the operating portion 62 may be provided on the upper portion 11b, similarly to the range hood 1 described above.

[0069] Therefore, according to the range hood 3 shown in FIG. 11, similar to the range hood 1 described above, the first light-transmitting cover 63 can function as indirect lighting, and design restrictions due to the installation of electrical equipment can be reduced.

[0070] <Fourth embodiment> 12, the airflow adjustment portion 20 is inclined with respect to the airflow straightening plate 30. The airflow adjustment portion 20 is fixed to the airflow guide surface 11 by a bracket 21. More specifically, the upper end side of the airflow adjustment portion 20 is inclined forward with respect to the surface of the current plate 30. The lower end side of the airflow adjustment portion 20 is in linear contact with the upper end side of the current plate 30. Therefore, the distance between the airflow adjustment portion 20 and the bottom portion 11a gradually narrows from the upper suction port 10a toward the opening portion 12.

[0071] Therefore, according to the range hood 4 shown in FIG. 12, similarly to the range hood 1 described above, the gas sucked in through the suction ports 10a on the left, right and upper sides can be accelerated and efficiently guided to the opening 12. In particular, in this range hood 4, the suction capacity of the upper suction port 10a is greater than the suction capacity of the left and right side suction ports 10a, 10a, so that even in a situation where a relatively large amount of smoke, etc. accumulates on the ceiling side, the smoke, etc. can be efficiently sucked into the upper suction port 10a.

[0072] <Fifth embodiment> The range hood 5 shown in FIG. 13 has a gap s between the airflow adjustment portion 20 and the airflow straightening plate 30, through which gas can be sucked in. That is, the air flow adjustment portion 20 is fixed to the air flow guide surface 11 by the bracket 21 in a state separated from the current plate 30 .

[0073] 13, the range hood 5 can draw in air from the gap s in addition to the suction ports 10a on the left, right, and upper sides, and can improve the suction capacity of the upper part of the air collection section 10. Therefore, like the range hood 4, it is useful in situations where smoke and the like tends to accumulate on the ceiling side.

[0074] Although not shown in the above modified example, the range hood 2 (see FIG. 10) can be provided with a second lighting section 65, etc., in the same manner as the range hood 1. Moreover, the range hoods 4 and 5 (see FIGS. 12 and 13) can be provided with a first lighting section 61 and a second lighting section 65, etc.

[0075] <Other Modifications> According to the embodiment of the air collection section 10 described above, the air flow guide surface 11 is formed in a concave shape and an opening 12 is provided at the bottom 11a thereof. However, as another example of the air collection section 10, it is also possible to form the air flow guide surface 11 as a flat surface over the entire surface and provide an opening 12 on the flat surface.

[0076] Furthermore, according to the air collection section 10 of the above embodiment, the surface having the opening 12 (the bottom 11a in the illustrated example) faces diagonally downward, but as other examples of the air collection section 10, it is also possible to have the surface having the opening 12 facing directly downward, or the surface having the opening 12 facing directly to the side.

[0077] In addition, the wind speed adjustment convex portion 31 in the above embodiment is formed so as to include the entire opening 12 and a part of the air flow guide surface 11 around the opening 12 when viewed from the direction opposite the opening 12 (see Figure 4), but as another example of this wind speed adjustment convex portion 31, it is possible to form it so as to include a part of the opening 12 and a part of the air flow guide surface 11 around the opening 12 when viewed from the direction opposite the opening 12.

[0078] In addition, in a particularly preferred embodiment of the straightening plate 30 in the above-mentioned embodiment, a corner side low surface portion 32 is provided at each of the two upper corners, and an edge side low surface portion 33 is provided at each of the four sides. However, other examples of this straightening plate 30 include a mode in which a corner side low surface portion 32 is provided at only one corner, a mode in which a portion that does not rise toward the air flow guide surface 11 is provided at a portion of the peripheral side that is not a corner, and a mode in which a portion that does not rise toward the air flow guide surface 11 is provided only at some sides.

[0079] In addition, in the above embodiment, the straightening plate 30 is rotated around the rotation axis 34a on one end as a fulcrum, but as other examples, it is possible to have the straightening plate 30 slidably or to have the straightening plate 30 detachably mounted.

[0080] In addition, in the above embodiment, the air flow adjustment unit 20 and the straightening plate 30 are used as shading members that block part of the light from the first lighting unit 61. As another example, however, a shading member may be provided as a separate member from the air flow adjustment unit 20 and the straightening plate 30, spaced apart from the air flow guide surface 11, and the first lighting unit 61 may be provided so as to emit light between this shading member and the air flow guide surface 11.

[0081] In addition, according to the above embodiment, the first lighting section 61 is provided so as to emit light between the light-shielding member (in the illustrated example, the air flow adjustment section 20 and the straightening plate 30) and the air flow guide surface 11, but as another example, it is also possible to provide the first lighting section 61 so as to emit light from the outside between the light-shielding member and the air flow guide surface 11 toward the space between the light-shielding member and the air flow guide surface 11.

[0082] In addition, in the above embodiment, the airflow adjustment section 20 or the straightening plate 30 is used as an electrical equipment mounting section for mounting electrical equipment, but as another example, it is also possible to fix an electrical equipment mounting section which is a member other than the airflow adjustment section 20 and the straightening plate 30 to the airflow guide surface 11, and mount the electrical equipment on this electrical equipment mounting section.

[0083] In addition, in the above embodiment, electrical components such as the first lighting unit 61 and the operating unit 62 are provided in either the air flow adjustment unit 20, the straightening plate 30, or the air flow guide surface 11, but as an example other than the illustrated example, it is also possible to provide the electrical components in multiple locations among the air flow adjustment unit 20, the straightening plate 30, and the air flow guide surface 11.

[0084] In the above embodiment, the airflow is adjusted using two members, the airflow adjustment section 20 and the rectifying plate 30, but as another example, it is possible to use a single member in which the airflow adjustment section 20 and the rectifying plate 30 are integrated, or an embodiment in which the airflow is adjusted using three or more members. In this case, the single member or the three or more members can be used as the electrical equipment mounting section and the light blocking member, respectively.

[0085] In addition, in the above embodiment, the electrical equipment is the first lighting unit 61, the electronic circuit 62a, the operating switch 62b, etc., but other examples of the electrical equipment can be sensors, motors, and other electrical components, etc.

[0086] In addition, in the range hood 3 configured as described above, both the operating unit 62 and the first lighting unit 61 are attached to the air flow guide surface 11. As another example, however, it is also possible to attach the first lighting unit 61 to the air flow guide surface 11 and the operating unit 62 to the air flow adjustment unit 20, or conversely, to attach the operating unit 62 to the air flow guide surface 11 and the first lighting unit 61 to the air flow adjustment unit 20.

[0087] Furthermore, the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the gist of the present invention. [Explanation of symbols]
