[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In some drawings, some of the detailed reference numerals used in other drawings are omitted. In the following embodiment, directions such as the up-down direction will be described based on a state in which an example of a range hood according to this embodiment is installed.

[0010] 1 to 6 are diagrams that diagrammatically show an example and a modified example of a range hood according to the present embodiment. As shown in Figures 1 and 4(b), the range hood 1 according to this embodiment includes a duct cover 12 that covers the exhaust duct 11 provided on the upper side of the hood section 13, and a performance-imparting cover 20 that is installed to cover the duct cover 12. With this configuration, the exhaust duct 11 is covered by the duct cover 12, so that the exhaust duct 11 does not stand out. In addition, since the duct cover 12 is covered by the performance-imparting cover 20, a performance effect can be imparted, and the feeling of a facility can be reduced compared to conventional duct covers and the like. The hood portion 13 is provided with an extension portion 14 that extends from the lower end side of the duct cover 12 to at least one side. In this embodiment, the performance-imparting cover 20 is installed so that its upper end portion is along the ceiling 2 and its lower end portion is along the outer peripheral end portion 15 of the extension portion 14 of the hood portion 13, and is provided with a cover body 21 that covers the duct cover 12. With this configuration, the duct cover 12, which is disposed in a position recessed from the extension portion 14 of the hood portion 13, can be covered by the cover body 21, so that adhesion of dust, oily smoke, etc. to the upper surface of the duct cover 12 and the extension portion 14 of the hood portion 13 can be prevented. In addition, since the cover body 21 is not disposed in a recessed position, the cleanability of the cover body 21 can also be improved.

[0011] Specifically, as shown in FIG. 1, the range hood 1 is installed above a cooking appliance 8 included in a kitchen device 5 that constitutes a floor cabinet of a kitchen. The kitchen equipment 5 includes a countertop (kitchen counter) 7 incorporating a cooking device 8 and a water tank (sink) 9, and a storage section 6 provided below the countertop 7. The cooking device 8 may be a gas stove, an IH cooking heater, or the like. The top plate 7 is elongated in one direction, with the cooking device 8 mounted on one side in the longitudinal direction and the water tank 9 mounted on the other side in the longitudinal direction. A work space is provided between the cooking device 8 and the water tank 9 on the top plate 7. The storage section 6 includes a first storage section 6A below the cooking device 8, a second storage section 6B below the work space, and a third storage section 6C below the water tank 9. The kitchen apparatus 5 is not limited to a configuration with three storage sections 6A, 6B, 6C, but may have two or less storage sections, or may have four or more storage sections.

[0012] In the illustrated example, the kitchen equipment 5 is not mounted on a wall but is installed in a so-called island type so that space is formed around it. In this case, the range hood 1 is a so-called center hood type that is suspended from the ceiling 2. In other words, the range hood 1 is installed in a manner that forms a space around it, similar to the kitchen equipment 5, but is not mounted on a wall. As shown in FIG. 4(b), the range hood 1 includes a fan box 10 that is provided above the hood portion 13 and that houses a blower. The fan box 10 has a generally rectangular parallelepiped shape that opens downward. The downward opening of the fan box 10 is connected to the hood section 13. An exhaust duct 11 that is connected to the outdoors via the back of the ceiling 2 or the like is connected to the top wall of the fan box 10. The top wall of the fan box 10 may be provided with an appropriate connection section to which the exhaust duct 11 is connected. The blower is installed in the fan box 10 such that the intake port faces the hood section 13 side and the exhaust port faces the exhaust duct 11 side. The blower may be configured to include a casing that houses an appropriate impeller such as a sirocco fan or a turbo fan, and an appropriate motor that rotates the impeller.

[0013] The duct cover 12 is provided so as to surround the fan box 10 and the exhaust duct 11 and to extend from the hood portion 13 to the ceiling 2. The duct cover 12 has four cover portions arranged adjacent to the four side surfaces of the fan box 10. Each cover portion of the duct cover 12 is arranged so that the thickness direction is substantially horizontal, and is a thin plate made of an appropriate metal. The duct cover 12 may have a U-shaped cover portion integrally formed in a substantially U-shape in a plan view so as to be arranged adjacent to each of the three side surfaces of the fan box 10, and a single flat cover portion arranged adjacent to the remaining one side surface of the fan box 10. The duct cover 12 may also be divided into a ceiling 2 side and a hood portion 13 side, that is, an upper and lower portion. This duct cover 12 may be attached to a suitable attachment object such as a hanging bolt that is provided so as to hang down from the ceiling 2, or the fan box 10, the hood portion 13, etc., by using a suitable fastener such as a screw.

[0014] As shown in FIG. 1(b), the hood portion 13 has an extension portion 14 extending from the lower end side of the duct cover 12 all around the four sides, and is substantially rectangular in plan view. That is, the extension portion 14 is provided in a flange shape on the lower end side of the duct cover 12 all around the four sides. Although described in detail later, the cover body 21 has four cover portions 22, 23, 24, and 27 that are installed along the four sides (15A, 15B, 15C, and 15D) of the extension portion 14 of the hood portion 13. With this configuration, the duct cover 12 can be covered all around the four sides by the cover body 21, and a performance can be provided all around the four sides. In addition, the adhesion of dust, oily smoke, and the like to the upper surface of the extension portion 14 extending in all four directions can be prevented. In addition, the cleaning properties of the cover parts 22, 23, 24, and 27 of the cover body 21 that cover these four sides can be improved. Also, as in this embodiment, the cover 20 is suitable for the range hood 1 that is hung from the ceiling rather than attached to the wall.

[0015] The hood portion 13 is a thin, substantially rectangular parallelepiped shape that opens downward. The hood portion 13 is provided with an appropriate straightening plate that is arranged to form a suction port between the four inner peripheral edges of the hood portion 13 and to cover the suction port of the blower. An appropriate oil filter (metal filter) or the like may be provided between the straightening plate and the suction port of the blower. The hood portion 13 may also be provided with an appropriate lighting device or the like that illuminates the lower side. The hood portion 13 may also be provided with an appropriate operating unit that turns such lighting device and the blower on and off. Such an operating unit may be provided on a side (in the illustrated example, a second end portion 15B described later) on one side (the cooking work space side) in the depth direction (kitchen depth direction) of the kitchen device 5, which is one of the four sides that constitute the outer peripheral end of the extension portion 14.

[0016] The four sides of the extension 14 are provided substantially parallel to the cover parts around the duct cover 12. In the illustrated example, the side on the center side of the kitchen device 5 in the frontage direction (kitchen frontage direction (longitudinal direction of the countertop 7)) is the first end 15A, and the side on the cooking work space side is the second end 15B. In addition, the side on the other side of the kitchen depth direction (dining space side) is the third end 15C, and the side on the outside of the kitchen frontage direction is the fourth end 15D. The dimension (thickness) of the extension 14 in the vertical direction may be about 20 mm to 60 mm. The upper surface of the extension 14 is substantially horizontal, but may be inclined downward as it moves away from the duct cover 12.

[0017] The width dimension of the hood portion 13 along the kitchen width direction is larger than the dimension of the outer periphery of the duct cover 12 along the same direction. The depth dimension of the hood portion 13 along the kitchen depth direction is larger than the dimension of the outer periphery of the duct cover 12 along the same direction. In the illustrated example, the dimensions of the extension portions 14 extending on both sides of the width direction of the duct cover 12 along the same direction are approximately the same, and the dimensions of the extension portions 14 extending on both sides of the depth direction of the duct cover 12 along the same direction are approximately the same. Also, an example is shown in which the dimensions of the extension portions 14 extending in the width direction and the dimensions of the extension portions 14 extending in the depth direction are approximately the same. That is, the duct cover 12 is provided so as to be located at the center of the hood portion 13 in a plan view. The dimensions of the extension portions 14 of the hood portion 13 along each direction are not limited to the above example, and may be various other dimensions.

[0018] The frontage and depth dimensions of hood portion 13 are larger than the frontage and depth dimensions of the top plate of cooking appliance 8 disposed below. The frontage dimension of hood portion 13 may be approximately 500 mm to 1200 mm, and may be set to, for example, 600 mm, 750 mm, 900 mm, etc., corresponding to the frontage dimension of the top plate of cooking appliance 8. The depth dimension of hood portion 13 may be approximately 400 mm to 800 mm. The range hood 1 configured as described above may be fixed, for example, by hanging it from a hanging bolt provided so as to hang down from the ceiling 2 via an appropriate mounting portion. The hood portion 13, duct cover 12, and fan box 10 that constitute this range hood 1 are not limited to the above-mentioned configuration, and may be appropriately configured similarly to known range hoods.

[0019] As shown in Fig. 1 and Fig. 4(b), the range hood 1 is provided with holding parts (18, 19) that detachably hold the cover body 21 of the effect-imparting cover 20. With this configuration, the cover body 21 can be detached from the range hood 1, making it easy to perform maintenance work including cleaning. It is also easy to replace the cover body 21 of the effect-imparting cover 20 that imparts effect. In this embodiment, the holding parts (18, 19) are supported on the side of the object to which the range hood 1 is fixed (the ceiling 2 in the illustrated example) rather than on a member that constitutes the range hood 1. With this configuration, the load on the range hood 1 can be reduced.

[0020] The cover body 21 of the effect-imparting cover 20 is decorated. With this configuration, it is possible to impart effect by the decoration. As shown in FIG. 5(b), the range hood 1 includes a light source (lower light source) 32 that irradiates the cover body 21 of the effect-imparting cover 20 with light. With this configuration, it is possible to impart dramatic effects with light. The lower light source 32 is installed between the duct cover 12 and the cover body 21 of the effect-imparting cover 20, and the cover body 21 is provided with the transmission parts 22b, 23b, 24b, and 27b that transmit the light from the lower light source 32. With this configuration, it is possible to make the lower light source 32 less noticeable, while still imparting dramatic effects with the light passing through the transmission parts 22b, 23b, 24b, and 27b of the effect-imparting cover 20.

[0021] Specifically, the cover body 21 is installed so as to be located on the outer periphery side of the duct cover 12 and so as to form a space between the cover body 21 and the duct cover 12. The cover body 21 includes a first cover portion 22 arranged along the first end 15A of the extension portion 14 of the hood portion 13, and a second cover portion 23 arranged along the second end 15B. The cover body 21 also includes a third cover portion 24 arranged along the third end 15C, and a fourth cover portion 27 arranged along the fourth end 15D. The first cover portion 22 is arranged substantially parallel to and opposite the cover portion of the duct cover 12 on the center side of the kitchen frontage direction. The second cover portion 23 is arranged substantially parallel to and opposite the cover portion of the duct cover 12 on the cooking work space side. The third cover portion 24 is arranged substantially parallel to and opposite the cover portion of the duct cover 12 on the dining space side. The fourth cover portion 27 is disposed substantially parallel to and opposite to the cover portion of the duct cover 12 that is on the outer side in the kitchen frontage direction.

[0022] As shown in Fig. 4 and Fig. 5, the cover parts 22, 23, 24, 27 are arranged so that the outer peripheral surface (in the illustrated example, the surface of the frame parts 22a, 23a, 24a, 27a described later) facing the side opposite to the duct cover 12 is substantially flush with the end faces of the ends 15A, 15B, 15C, 15D which are the leading end faces in the extension direction of the extension part 14. In other words, the cover body 21 is arranged so that its outer peripheral surface is substantially flush with the outer peripheral end face of the extension part 14. With this configuration, cleaning properties can be further improved. Also, even if an operating part is present on the outer peripheral end face of the extension part 14, the operating part will not be covered by the cover body 21. These cover portions 22, 23, 24, and 27 are disposed so that their lower end surfaces abut against or are close to the upper surface of the extension portion 14. In addition, these cover portions 22, 23, 24, and 27 are disposed so that their upper end surfaces abut against or are close to the ceiling 2.

[0023] These cover portions 22, 23, 24, and 27 may be flame retardant, and preferably non-flammable. In this embodiment, the cover portions 22, 23, 24, 27 include substantially rectangular flat-plate-shaped transmitting portions 22b, 23b, 24b, 27b, and frame portions 22a, 23a, 24a, 27a provided to surround the four periphery ends of the transmitting portions 22b, 23b, 24b, 27b. The transparent parts 22b, 23b, 24b, and 27b may be non-combustible and light-transmitting plate materials such as glass plates and fiber-reinforced plastics. The transparent parts 22b, 23b, 24b, and 27b may be smoked glass or frosted glass, or may be plate materials with various patterns (decorations) such as checkered, malle, aqua, rain, and mist. The transparent parts 22b, 23b, 24b, and 27b may be configured such that a light-transmitting film that imparts a pattern (decoration) such as Japanese paper or a resin film is laminated on a base material made of a non-combustible and light-transmitting plate material as described above. In the illustrated example, the transparent parts 22b, 23b, 24b, and 27b are provided with a cross-hatched pattern (decoration), but are not limited to such an example, and may be provided with various other patterns (decorations).

[0024] The frame parts 22a, 23a, 24a, 27a are larger in thickness dimension along the thickness direction of each cover part 22, 23, 24, 27 than the thickness dimension along the same direction of the transmission parts 22b, 23b, 24b, 27b. The frame parts 22a, 23a, 24a, 27a are provided with holding grooves that constitute holding parts that hold the four peripheral ends of the transmission parts 22b, 23b, 24b, 27b. The frame parts 22a, 23a, 24a, 27a may be formed in a square column shape (square tube shape) and may be made of a suitable metal. The frame parts 22a, 23a, 24a, 27a of each cover part 22, 23, 24, 27 may be formed in a frame shape by welding, fasteners, or the like as appropriate.

[0025] In this embodiment, as shown in Fig. 3, the cover body 21 including the above-mentioned four cover parts 22, 23, 24, 27 is configured such that the second cover part 23 and the third cover part 24 are integrally provided on both ends of the first cover part 22 in the kitchen depth direction. That is, the first cover part 22, the second cover part 23, and the third cover part 24 are integrally formed in a substantially U-shape in plan view. The first cover part 22, the second cover part 23, and the third cover part 24 may be integrated by joining their respective frame parts 22a, 23a, 24a by welding or an appropriate fastener. The first cover portion 22, the second cover portion 23, and the third cover portion 24 are configured to be detachably held by the fourth cover portion 27 held by holding portions (18, 19) described below. With this configuration, the cover body 21 can be attached and detached more easily than, for example, a configuration in which four independent cover portions are held by appropriate holding portions.

[0026] The end faces of the second cover part 23 and the third cover part 24 on the side opposite to the first cover part 22 side are brought into contact with or close to the back faces (the faces facing the duct cover 12 side) of both ends of the fourth cover part 27 in the kitchen depth direction (see FIG. 4(a)). That is, the fourth cover part 27, the second cover part 23 and the third cover part 24 are brought into contact with the fourth cover part 27. That is, when the cover body 21 is installed, the side end faces on both sides of the fourth cover part 27 in the kitchen depth direction are the faces exposed on the indoor side of the cover body 21. Also, each surface facing the side opposite to the duct cover 12 in the thickness direction of each cover part 22, 23, 24, 27 is the face exposed on the indoor side of the cover body 21. These surfaces and side end faces may be subjected to an easy-cleaning treatment. Such an easy-cleaning treatment may be any treatment that makes it easy to clean these surfaces and side end faces, and may be, for example, a water-repellent treatment or a hydrophilic treatment, or a photocatalytic coating. The easy-cleaning treatment is not limited to coating or painting, but may be a treatment such as surface modification.

[0027] As shown in Fig. 2(b), Fig. 3 and Fig. 5, the second cover part 23 and the third cover part 24 are provided with held parts (25, 26) that are detachably held by the holding parts (30, 31) provided on the fourth cover part 27. The held parts (25, 26) are provided on the end faces of the second cover part 23 and the third cover part 24 on the side different from the first cover part 22 side. In the illustrated example, the held parts (25, 26) include upper end held parts 25, 25 provided on the upper end of each end face of the second cover part 23 and the third cover part 24, and lower end held parts 26, 26 provided on the lower end of each end face. These upper end held parts 25, 25 and lower end held parts 26, 26 are provided on the frame parts 23a, 24a of the second cover part 23 and the third cover part 24. In the illustrated example, the upper end held parts 25, 25 are formed in a potbellied hole shape formed so that a large diameter part through which the head of a bolt-shaped upper end holding part 30 of the fourth cover part 27 described later can be inserted and a small diameter part through which the shaft part of the upper end holding part 30 can be inserted are connected. These upper end held parts 25, 25 are provided so as to open at each end face of the second cover part 23 and the third cover part 24, and so that the small diameter part is higher than the large diameter part. The lower end held parts 26, 26 will be described later.

[0028] As shown in FIG. 2(b), the holding portions (30, 31) of the fourth cover portion 27 are provided on the back surfaces of both ends in the kitchen depth direction in correspondence with the held portions (25, 26) of the second cover portion 23 and the third cover portion 24. In the illustrated example, the holding portions (30, 31) include upper end holding portions 30, 30 provided at the upper ends of both ends in the kitchen depth direction, and lower end holding portions 31, 31 provided at the lower ends of both ends. These upper end holding portions 30, 30 and lower end holding portions 31, 31 are provided on the frame portion 27a of the fourth cover portion 27. 5(a), the upper end holding parts 30, 30 are provided so as to protrude from the back surface of the fourth cover part 27 in the thickness direction of the fourth cover part 27, and are configured so as to have a head part with a larger diameter than the shaft part provided on the tip side of the shaft part on the base end side. The head part of these upper end holding parts 30, 30 is inserted through the large diameter part of the upper end held parts 25, 25, and is hooked and locked on the hole edge of the small diameter part of the upper end held parts 25, 25.

[0029] The lower end holding parts 31, 31 and the lower end held parts 26, 26 may have one being a catch part (latch part) and the other being a strike part (latch receiving part) that is engaged and held by the other. Such lower end holding parts 31, 31 and lower end held parts 26, 26 may be so-called push latches (push catches) that are engaged and released by a pressing operation. The first cover part 22, the second cover part 23 and the third cover part 24 may be arranged so that a small gap is formed between them and the ceiling 2 so that the held parts (25, 26) can be engaged with and disengaged from the holding parts (30, 31) of the fourth cover part 27. Such a gap may be, for example, about 5 mm to 20 mm. The lower end holding portions 31, 31 and the lower end held portions 26, 26 are not limited to the configuration described above, but may have one being a magnet and the other being an attached portion that is attracted to the magnet, or may be a hook-and-loop fastener, or may have various other configurations. Similarly, the upper end holding portions 30, 30 and the upper end held portions 25, 25 are not limited to the above-described configuration, but may be configured to include a hooking recess and a hooking protrusion that is hooked onto the hooking recess, or may have various other configurations.

[0030] As shown in Fig. 2(b) and Fig. 4(b), the fourth cover part 27 is provided with held parts (28, 29) that are held by the holding parts (18, 19). The held parts (28, 29) are provided on the back surface of both end parts of the fourth cover part 27 in the kitchen depth direction. In the illustrated example, the held parts (28, 29) are provided adjacent to the center side in the kitchen depth direction of the upper end holding parts 30, 30 and the lower end holding parts 31, 31 provided at both ends in the kitchen depth direction, respectively, and include upper end held parts 28, 28 on the upper end side and lower end held parts 29, 29 on the lower end side. These upper end held parts 28, 28 and lower end held parts 29, 29 are provided on the frame part 27a of the fourth cover part 27. The holding portions (18, 19) are provided on both sides in the kitchen depth direction of the duct cover 12, on the outside in the kitchen width direction, in correspondence with the held portions (28, 29). These holding portions (18, 19) are provided on hanging bolts 17, 17 constituting a hanging holding portion provided so as to hang down from the ceiling 2. These hanging bolts 17, 17 are provided so as to be located between the fourth cover portion 27 and the cover portion of the duct cover 12 facing it. These holding portions (18, 19) include upper end holding portions 18, 18 that hold upper end held portions 28, 28, and lower end holding portions 19, 19 that hold lower end held portions 29, 29.

[0031] As shown in FIG. 4(b), the upper end holding parts 18, 18 are provided so as to be located near the ceiling 2 of the hanging bolts 17, 17. These upper end holding parts 18, 18 are hook parts having a protruding piece protruding upward at the tip of a piece extending from the hanging bolts 17, 17 toward the fourth cover part 27. The upper end held parts 28, 28 are hook parts having a protruding piece protruding downward at the tip of a piece extending from the upper end of the back surface of the fourth cover part 27 toward the duct cover 12. In other words, the upper end held parts 28, 28 are hooked and held by the upper end holding parts 18, 18. The fourth cover part 27 may be arranged so that a small gap is formed between the ceiling 2 and the upper end holding parts 18, 18 so that the upper end held parts 28, 28 can be engaged and disengaged with respect to the upper end holding parts 18, 18. Such a gap may be, for example, about 5 mm to 20 mm. The lower end holding portions 19, 19 are provided so as to be located near the lower ends of the hanging bolts 17, 17. As shown in Figures 2 and 4(b), these lower end holding portions 19, 19 constitute lock receiving portions that receive locking portions 29b, 29b of lower end held portions 29, 29 operated by operating portions 29a, 29a to the locking side and the unlocking side.

[0032] The operating portions 29a, 29a of the lower end held portions 29, 29 are provided so as to be exposed on the front surface side of the fourth cover portion 27. Such operating portions 29a, 29a may be operating portions provided with a cross hole, a slot, or the like that can be rotated around an axis along the thickness direction of the fourth cover portion 27 by a tool such as a screwdriver or a coin. The locking parts 29b, 29b are provided so as to protrude from the rear surface of the fourth cover part 27 in the thickness direction of the fourth cover part 27. The locking parts 29b, 29b rotate around an axis along the thickness direction to the lock side and the unlock side with the operation of the operating parts 29a, 29a. In the illustrated example, the locking parts 29b, 29b are configured to have a lock piece part protruding in the radial direction at the tip part in the protruding direction. The lower end holding parts 19, 19 are provided with an appropriate recess for receiving the locking parts 29b, 29b in the unlocked state and for engaging the locking parts 29b, 29b in the locked state. The holding parts (18, 19) and the held parts (28, 29) are not limited to the above-mentioned configurations and may have various other configurations.

[0033] When installing the cover body 21 configured as above, as shown in Fig. 4(b), the upper end held portions 28, 28 of the fourth cover portion 27 are hooked and held by the upper end holding portions 18, 18. Then, the locking portions 29b, 29b in the unlocked state are inserted into the recesses of the lower end holding portions 19, 19, and the operating portions 29a, 29a are operated from the unlocked side to the locked side to enter the locked state. 5(a) and (b), the first cover part 22, the second cover part 23, and the third cover part 24 are held by the fourth cover part 27 held by the holding parts (18, 19) as described above. That is, the upper end held parts 25, 25 of the second cover part 23 and the third cover part 24 are held by the upper end holding parts 30, 30 of the fourth cover part 27, and the lower end held parts 26, 26 of the second cover part 23 and the third cover part 24 are held by the lower end holding parts 31, 31 of the fourth cover part 27. In this way, the cover main body 21 is installed.

[0034] On the other hand, when removing the cover body 21, the lower end held portions 26, 26 of the second cover part 23 and the third cover part 24 are detached from the lower end holding portions 31, 31 of the fourth cover part 27. Then, the second cover part 23 and the third cover part 24 are slightly displaced upward, and these upper end held portions 25, 25 are detached from the upper end holding portions 30, 30 of the fourth cover part 27. Then, the operating portions 29a, 29a are operated from the locked side to the unlocked side to set the locking portions 29b, 29b in an unlocked state and are detached from the recesses of the lower end holding portions 19, 19. Then, the fourth cover portion 27 is slightly displaced upward to detach the upper end held portions 28, 28 from the upper end holding portions 18, 18. This allows the cover body 21 to be removed.

[0035] The light source (lower light source) 32 is not shown in Figures 2(b) to 5(a), but is held by a light source holder 33 provided on the back side of the cover body 21, as shown in Figure 5(b). The lower light source 32 may be provided at a plurality of locations spaced apart in the circumferential direction on the inner circumferential side of the cover body 21, or may be provided so as to extend in the circumferential direction. Such a lower light source 32 may be configured with an LED (light emitting diode) as a light emitting element, or may be a light guide that emits light from the light emitting element from a side surface, or the like. The light source holding portion 33 is provided in a region near the lower end on the back side of the cover body 21 so that a space is formed between the light source holding portion 33 and the upper surface of the extension portion 14 of the hood portion 13. In the illustrated example, the light source holding portions 33, 33 for holding the lower light sources 32, 32 are provided on the back sides of the frame portions 22a, 27a of the first cover portion 22 and the fourth cover portion 27 constituting the cover body 21, respectively, but the present invention is not limited to such an example. Instead of or in addition to the frame portions 22a, 27a of the first cover portion 22 and the fourth cover portion 27, the light source holding portions 33, 33 for holding the lower light sources 32, 32 may be provided on the back sides of the frame portions 23a, 24a of the second cover portion 23 and the third cover portion 24, respectively.

[0036] The lower light source 32 is provided so as to irradiate light toward the transmitting parts 22b, 27b of the cover parts (the first cover part 22 and the fourth cover part 27 in the illustrated example) provided with the light source holding part 33 that holds the lower light source 32. In other words, the lower light source 32 is provided so that the light from the lower light source 32 passes through the transmitting parts 22b, 27b from the diagonally lower side to the diagonally upper side. The lower light sources 32, 32 provided on the first cover portion 22 and the fourth cover portion 27 may further irradiate light toward the transmission portions 23b, 24b of the second cover portion 23 and the third cover portion 24. The position and number of the lower light sources 32 are not limited to those shown in the figures, and various other modifications are possible. Also, a suitable operation unit for turning the lower light source 32 on and off may be provided at a suitable location on the hood portion 13 or the cover body 21. Also, for example, the lower light source 32 may be turned on and off in conjunction with the turning on and off of the blower of the range hood 1. With such a configuration, the on and off state of the blower of the range hood 1 can be recognized from a distant position.

[0037] The cover body 21 is not limited to the above-mentioned configuration. For example, the first cover part 22 and the second cover part 23 may be integrally formed in a substantially L-shape in plan view, and the third cover part 24 and the fourth cover part 27 may be integrally formed in a substantially L-shape in plan view. Furthermore, each of these cover parts 22, 23, 24, and 27 may be separate. In these cases, the holding parts (18, 19) and the held parts (28, 29) may be modified as appropriate and necessary. The holding parts (30, 31) and the held parts (25, 26) that join the cover parts together may also be modified as appropriate and necessary. Instead of providing the holding parts (18, 19) on the hanging bolt 17 hanging from the ceiling 2, the holding parts (18, 19) may be provided on the range hood 1 side, or may be provided on both the ceiling 2 side and the range hood 1 side. In the above example, the cover body 21 is disposed so that its outer peripheral surface is substantially flush with the outer peripheral end surface of the extension portion 14, but the lower end surface of the cover body 21 may be disposed so that it is substantially flush with the lower surface of the hood portion 13. That is, the lower end of the cover body 21 is disposed so as to be aligned with the outer peripheral end surface of the extension portion 14 may be configured so that the outer peripheral surface of the cover body 21 is substantially flush with the outer peripheral end surface of the extension portion 14, or may be configured so that the lower end surface of the cover body 21 is substantially flush with the lower surface of the hood portion 13. In the latter case, the lower end surface of the cover body 21 may also be subjected to an easy-cleaning treatment. In addition, the cover body 21 is not limited to a shape having an outer periphery that is substantially rectangular parallelepiped, and may be configured so that a part or the entire circumference of the outer peripheral surface is curved. The cover body 21 may have various other configurations.

[0038] Next, an example of a range hood equipped with a modified example of the effect-imparting cover will be described with reference to FIG. In each of the following modified examples, differences from the previously described example will be mainly described, and explanations of similar configurations will be omitted or briefly described. In each modified example, explanations of the same effects as those of the previously described example will be omitted or briefly described.

[0039] FIG. 6(a) illustrates a schematic diagram of an example of a range hood equipped with an example of an effect-imparting cover according to a first modified example. In this modified example, the main difference from the above-described example is the configuration of a cover body 21A of an effect-imparting cover 20A installed on a range hood 1A. In this modified example, the cover body 21A is provided so as to be located on the inner circumferential side (the duct cover 12 side) of the outer circumferential end portion 15 of the extension portion 14 of the hood portion 13. In this modified example, a lower light source 32 and an upper light source 34 are provided vertically spaced apart on the back surface of the cover body 21A. As described above, the lower light source 32 and the upper light source 34 may be provided at multiple locations on the inner periphery side of the cover body 21A with a circumferential gap therebetween, or may be provided so as to extend in the circumferential direction.

[0040] The lower light source 32 is held by a light source holding portion 33 similar to the above. The upper light source 34 is held by a light source holding portion 35 provided at the upper end portion (frame portion) of the back surface side of the cover main body 21A. As described above, the lower light source 32 and the upper light source 34 are provided so as to irradiate light toward the transmitting portions 22b, 23b (see FIG. 3, etc.), 24b, and 27b of the cover main body 21A. The upper light source 34 is provided so that light from the upper light source 34 passes through the transmitting portions 22b, 23b (see FIG. 3, etc.), 24b, and 27b from the diagonally upward side to the diagonally downward side. Instead of the configuration in which the light sources (lower light source 32 and upper light source 34) are provided on the back side of the cover main body 21, 21A as in this modified example and the above example, the following may be used. For example, the light sources may be provided in the frame parts 22a, 23a, 24a, 27a so as to irradiate the outer peripheral edge parts of the transmission parts 22b, 23b, 24b, 27b with light. The position of the light source that irradiates light toward the transmission parts 22b, 23b, 24b, 27b is not limited to the above example, and may be various other positions.

[0041] FIG. 6(b) illustrates a schematic diagram of an example of a range hood equipped with an example of an effect-imparting cover according to the second modified example. In this modified example, the main difference from the above-described example is the configuration of a cover body 21B of an effect-imparting cover 20B installed on a range hood 1B. In this modified example, the light sources (the lower light source 32 and the upper light source 34) are installed on the indoor side of the cover body 21B of the effect-imparting cover 20B, and the effect-imparting cover 20B is provided with reflecting portions 22Ab, 24Ab, and 27Ab that reflect light from the lower light source 32 and the upper light source 34. With this configuration, it is possible to impart effect by the light reflected by the reflecting portions 22Ab, 24Ab, and 27Ab of the effect-imparting cover 20B.

[0042] The lower light source 32 and the upper light source 34 are held by light source holders 33, 35 similar to those described above, which are provided on the outer periphery, which is the front surface side of the cover main body 21B. In the illustrated example, similar to the first modified example, the light source holders 33, 35 that respectively hold the lower light source 32 and the upper light source 34 are provided at intervals in the vertical direction on the front surface side of the cover main body 21B. Similar to the above, the lower light source 32 and the upper light source 34 may be provided at a plurality of locations at intervals in the circumferential direction on the outer periphery side of the cover main body 21B, or may be provided so as to extend in the circumferential direction. In this modification, similarly to the above-described first modification, the cover body 21B is provided so as to be located on the inner circumferential side (duct cover 12 side) of the outer circumferential end portion 15 of the extension portion 14 of the hood portion 13. In the illustrated example, an example is shown in which the cover body 21B is provided so that the light source holding portions 33, 35 do not protrude outer circumferentially further than the tip face of the extension portion 14 of the hood portion 13 in the extension direction.

[0043] The reflecting parts 22Ab, 24Ab, 27Ab are generally rectangular flat plates similar to the above-mentioned transmitting parts 22b, 23b, 24b, 27b, and may be non-flammable glass plates, fiber-reinforced plastics, or other plate materials. The reflecting parts 22Ab, 24Ab, 27Ab may be provided with an appropriate reflective layer that reflects the light from the lower light source 32 and the upper light source 34, and may be subjected to mirror finishing. The reflecting parts 22Ab, 24Ab, 27Ab are held at their four peripheral ends by the frame parts 22a, 24a, 27a, similar to the above. In the illustrated example, the third cover part is omitted from the illustration, but the third cover part is also provided with a similar frame part and reflecting part. The light from the lower light source 32 is reflected by the reflecting portions 22Ab, 24Ab, and 27Ab, and is irradiated obliquely upward. The light from the upper light source 34 is reflected by the reflecting portions 22Ab, 24Ab, and 27Ab, and is irradiated obliquely downward. In this modification and the first modification, an example in which the lower light source 32 and the upper light source 34 are provided is shown, but a configuration in which only one of them is provided may also be used.

[0044] The different configurations described in the above examples may be modified, rearranged, or combined as necessary. For example, the cover body 21B described in the second modified example may be configured to be provided along the outer peripheral end 15 of the extension 14 of the hood 13. Further, in each of the above examples, the lower light source 32 (or the lower light source 32 and the upper light source 34) is provided, but a mode in which a light source is provided at a vertical midpoint or the like may also be used. In addition, in each of the above examples, the cover parts of the cover bodies 21, 21A, and 21B are configured to include a plate material that constitutes a transmissive part and a reflective part, and a frame part. However, each cover part may be configured to be a flat plate having a uniform thickness over approximately the entire surface. In addition, in each of the above examples, a light source (lower light source 32 (or lower light source 32 and upper light source 34)) that irradiates light onto the cover main body 21, 21A, 21B is provided, but such a light source may not be provided. In other words, the cover main body 21, 21A, 21B may be provided with only a decoration (pattern) to provide a special effect.

[0045] In the above-mentioned examples, the range hood 1, 1A, 1B of the center hood type are illustrated, but the present invention is not limited to such an embodiment. For example, the range hood may be a side hood type range hood applied to a kitchen device 5 in which the side end face of the first storage section 6A side, which is the side where the cooking device 8 is provided, is abutted against a wall and installed in a facing type (peninsula type). Alternatively, the range hood may be a wall-mounted hood type range hood applied to a kitchen device 5 in which the entire back side, which is one side in the kitchen depth direction, is abutted against a wall and installed in a wall-mounted type. In these cases, the range hood may be configured to have a duct cover 12 that is approximately U-shaped in plan view and surrounds three sides so as to open toward the wall side. In addition, in these cases, the range hood may be configured to have an extension part 14 that extends in three directions from the lower end side of the duct cover 12 provided in the hood part 13, and the side of the hood part 13 where the extension part 14 is not provided is attached to the wall. In these cases, the cover bodies 21, 21A, 21B may not be provided with the fourth cover parts 27, 27A as described above. In these cases, the hanger bolts 17 as described above may not be provided, and the wall body may be provided with the same holding parts (upper end holding part 30 and lower end holding part 31). In other words, the holding parts (upper end holding part 30 and lower end holding part 31) provided on the wall body may be used as holding parts that detachably hold the cover bodies 21, 21A, 21B.

[0046] In the case of a wall-mounted range hood, when a wall cupboard or a wall body is adjacent to both sides in the width direction, a fascia-shaped duct cover whose front surface is arranged substantially flush with the front surface of the wall cupboard may be provided instead of the duct cover 12 that surrounds three sides as described above. In this case, the extension portion 14 of the hood portion 13 extends only toward the cooking work space side. In this case, the cover main body 21, 21A, 21B may be provided along three sides of the extension portion 14 that is provided to protrude beyond the front surface of the wall cupboard. In other words, the dimensions of the second cover portion 23 and the third cover portion 24 along the kitchen depth direction may be small. In this case, the fascia-shaped duct cover may be provided with the same holding portions (upper end holding portion 30 and lower end holding portion 31) as described above, or may be provided with holding portions at other locations. The configurations of each member and each part of the performance-imparting covers 20, 20A, 20B and the configurations of each member and each part of the range hoods 1, 1A, 1B in the above examples are merely examples, and various other modifications are possible.
