Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] Currently, in range hoods with LED lights installed on the casing, the lights are positioned close to the air inlet. To protect the lights, a protective cover is designed in the area of ​​the lights. However, one end of the light connection wire needs to pass through the protective cover to connect to the light, while the other end passes directly through the smoke collection chamber to connect to the power board on the top of the range hood. This causes grease in the smoke collection chamber to adhere to the light connection wire, and the grease on the light connection wire will flow along the wire harness to the light area, affecting the normal use of the light. Utility Model Content

[0003] The purpose of this utility model is to provide a range hood that can effectively reduce or even prevent oil stains from flowing along the lamp connection wire to the lamp body.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a range hood, including a first housing assembly and a lamp connecting wire. The first housing assembly has a smoke collection chamber, an air inlet communicating with the smoke collection chamber, and a wire passing hole located above the air inlet. The lamp connecting wire passes through the smoke collection chamber from the smoke collection chamber and exits the smoke collection chamber through the wire passing hole. The height of the wire passing hole is not lower than the lowest point in the smoke collection chamber before the lamp connecting wire enters the wire passing hole.

[0006] Furthermore, the first housing assembly also has a wiring hole for the lamp connection wire outside the smoke collection chamber to extend into the smoke collection chamber.

[0007] Furthermore, when the lamp connecting wire includes multiple strands of wire, the wiring holes are configured to correspond one-to-one with multiple wiring holes for different strands of wire to pass through so that each strand of wire is connected to a different lamp body.

[0008] Furthermore, the plurality of wiring holes are arranged in a straight line.

[0009] Furthermore, the lamp connecting wire includes at least one wire harness, the wire harness including a first inner extension section, an outer extension section and a second inner extension section connected in sequence, the first inner extension section being at least partially located inside the smoke collection cavity, the outer extension section extending from the wire hole to the wiring hole and located outside the smoke collection cavity, and the second inner extension section being located inside the smoke collection cavity and the end away from the outer extension section being used for connection to the lamp body.

[0010] Furthermore, when the height of the threading hole is equal to the lowest point in the smoke collection chamber before the first inner extension section enters the threading hole, the outer extension section includes a first line segment extending out of the threading hole, the first line segment extending horizontally or downward.

[0011] Furthermore, a lampshade is provided inside the smoke collection chamber, and an oil-proof cavity is formed between the lampshade and the first housing assembly;

[0012] Both the wiring hole and the second inner extension are located inside the oil-proof cavity; or the wiring hole is located outside the oil-proof cavity, the second inner extension extends from the wiring hole into the oil-proof cavity, and the portion of the second inner extension outside the oil-proof cavity has a downwardly curved section.

[0013] And / or, the range hood further includes a connector connected to the oil-proof cavity, or the connector connected to the outer wall of the smoke collection cavity.

[0014] Furthermore, one end of the lampshade is connected to the first housing assembly via a connector, and the other end of the lampshade has a wing plate, the side of the wing plate facing the first housing assembly having a recessed groove for receiving adhesive.

[0015] Furthermore, the first housing assembly is connected to a first limiting structure, which is installed inside the smoke collection chamber. The first limiting structure is used to limit the position of the first inner extension and / or the second inner extension relative to the first housing assembly.

[0016] Furthermore, the first housing assembly is connected to a second limiting structure, which is used to define the position of the outer extension relative to the first housing assembly.

[0017] Furthermore, it also includes a fixing plate, which is connected to the first housing assembly and forms a wiring cavity between the fixing plate and the first housing assembly. The fixing plate and the first housing assembly restrict the lamp connection wire located outside the smoke collection cavity within the wiring cavity in a direction perpendicular to the plane where the fixing plate is located.

[0018] Furthermore, the outer surface of the first housing assembly is recessed with a mounting groove, the mounting groove having the wire hole and a wiring hole for the lamp connection wire located outside the smoke collection chamber to extend into the smoke collection chamber.

[0019] Furthermore, the first housing assembly includes an air inlet plate having the air inlet, the edge of the air inlet plate being inclined from the outer surface of the first housing assembly to the inner cavity, and the lamp body being mounted on the air inlet plate.

[0020] The range hood provided by this utility model can produce the following beneficial effects:

[0021] In the range hood provided by this utility model, the first housing assembly has a wire hole above the air inlet. The lamp connecting wire can pass through the wire hole from the smoke collection chamber to the outside of the first housing assembly. Since the height of the wire hole is not lower than the lowest point of the lamp connecting wire in the smoke collection chamber before it passes through the wire hole, the oil stains attached to the lamp connecting wire in the smoke collection chamber are easy to drip off before the lamp connecting wire passes through the wire hole, which can effectively reduce or even prevent the oil stains from continuing to flow along the lamp connecting wire to the lamp body.

Detailed Implementation

[0035] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0039] This embodiment provides a range hood, such as... Figures 1 to 4 As shown, the device includes a first housing assembly 1 and a lamp connecting wire 5. The first housing assembly 1 has a smoke collection chamber 17, an air inlet 111 communicating with the smoke collection chamber 17, and a wire hole 131 located above the air inlet 111. The lamp connecting wire 5 passes through the smoke collection chamber 17 from the smoke collection chamber 17 through the wire hole 131. The height of the wire hole 131 is not lower than the lowest point of the lamp connecting wire 5 in the smoke collection chamber 17 before it passes through the wire hole 131.

[0040] In the range hood provided in the above embodiment, the first housing assembly 1 has a wire hole 131 above the air inlet 111, and the lamp connecting wire 5 can pass through the wire hole 131 from inside the smoke collection chamber 17 to the outside of the first housing assembly 1, such as... Figure 4 As shown, since the height of the wire hole 131 is not lower than the lowest point of the lamp connecting wire 5 in the smoke collection chamber 17 before it enters the wire hole 131, the oil stains on the lamp connecting wire 5 in the smoke collection chamber 17 are easy to drip into the smoke collection chamber 17 before the lamp connecting wire 5 exits the wire hole 131. This can effectively reduce or even prevent the oil stains from continuing to flow along the lamp connecting wire 5 to the lamp body, thus ensuring the life of the lamp body.

[0041] In an optional embodiment, the first housing assembly 1 also has a wiring hole 132 for the lamp connection wire 5 outside the smoke collection chamber 17 to extend into the smoke collection chamber 17.

[0042] In use, the lamp connecting wire 5 can pass through the smoke collection cavity 17 through the wire hole 131 and exit the smoke collection cavity 17. After the wiring is completed outside the smoke collection cavity 17, it enters the smoke collection cavity 17 through the wiring hole 132 and connects to the lamp body 3. The lamp body 3 can be set at the edge of the air inlet 111.

[0043] In an optional embodiment, the first housing assembly 1 includes an air inlet plate 11 having an air inlet 111, the edge of the air inlet plate 11 being inclined from the outer surface of the first housing assembly 1 to the inner cavity, and the lamp body 3 being mounted on the air inlet plate 11.

[0044] The above-described embodiments are more suitable for use in ultra-thin side-suction smoke extraction machines, such as... Figures 5 to 7 As shown, a flap 6 is rotatably connected to the outside of the air inlet plate 11. When the flap 6 is closed, the structure behind the flap 6 needs to be hidden inside the first housing assembly 1. Due to the small depth requirement of the first housing assembly 1, the flap 6 is also designed to be very thin in order to meet sufficient air intake area. The space behind the flap 6 is insufficient to design space for installing the lamp body 3. Furthermore, the top of the first housing assembly 1 cannot be used to install the lamp body 3. When the lamp body 3 shines, diffuse reflection will occur due to the movable flap 6, affecting the user's vision. Based on the above two situations, in the above embodiment, the lamp body 3 is installed on the air inlet plate 11 to meet the angle of light path illumination of the cookware, while also providing sufficient space for installing the lamp body 3.

[0045] The air intake plate 11 can have one lamp body 3 or multiple lamp bodies 3. When multiple lamp bodies 3 are provided, each lamp body 3 needs to be powered. At this time, the lamp connection line 5 can include a multi-strand wire harness 51.

[0046] In an optional embodiment, when there are multiple lamp bodies 3, in order to facilitate the connection of each wire harness 51 to the corresponding lamp body 3, the wiring holes 132 are configured to be one-to-one multiple, and the multiple wiring holes 132 are used for different wire harnesses 51 to pass through so that each wire harness 51 can be connected to different lamp bodies 3.

[0047] Specifically, to avoid the wiring harness inside the first housing assembly 1 being too messy, the wire hole 131 can be configured as one. After the lamp connecting wire 5 extends out of the wire hole 131 from the smoke collection chamber 17, it can be divided into multiple strands, with each strand of wire 51 extending out from a different wiring hole 132.

[0048] like Figure 3 and Figure 4 As shown, taking two lamp bodies 3 as an example, the lamp connecting wire 5 extends out of the wire hole 131 from the smoke collection cavity 17 and then branches into two strands. One strand passes through a wiring hole 132 and re-enters the smoke collection cavity 17, connecting with one lamp body 3. The other strand continues to extend in the wiring cavity 4, passes through another wiring hole 132 of the first housing assembly 1 and enters the smoke collection cavity 17, connecting with the other lamp body 3.

[0049] The location of each wiring hole 132 is related to the extension direction of each wire bundle 51. Preferably, the multiple wiring holes 132 are arranged in a straight line to avoid unnecessary tearing of the outer sheath of the lamp connecting wire 5 at the fork.

[0050] Of course, the wiring holes 132 can also be distributed irregularly.

[0051] In alternative implementations, such as Figure 5As shown, the lamp connecting wire 5 includes at least one wire harness 51. To facilitate the description of the shape of each segment of the wire harness 51 and its connection relationship with other structures, the wire harness 51 is configured to include a first inner extension segment 53, an outer extension segment 54 and a second inner extension segment 55 connected in sequence. The first inner extension segment 53 is at least partially located inside the smoke collection cavity 17. The outer extension segment 54 extends from the wire hole 131 to the wiring hole 132 and is located outside the smoke collection cavity 17. The second inner extension segment 55 is located inside the smoke collection cavity 17 and the end away from the outer extension segment 54 is used to connect to the lamp body 3.

[0052] The aforementioned wiring harness 51 includes a first inner extension section 53, an outer extension section 54, and a second inner extension section 55. It is understood that regardless of which section the oil is isolated or the oil is prevented from continuing to extend into the lamp body 3, the oil pollution of the lamp body 3 can be reduced or even avoided.

[0053] For example, the lowest point of the part of the lamp connecting wire 5 before it enters the wire hole 131 in the smoke collection chamber 17 can be lower than the wire hole 131, so that the oil can drip off naturally at the lowest point under the action of gravity.

[0054] like Figure 4 As shown, when the height of the threading hole 131 is equal to the lowest point of the first inner extension section 53 in the smoke collection chamber 17 before it enters the threading hole 131, the outer extension section 54 includes the first line segment 52 that passes through the threading hole 131.

[0055] The first line segment 52 can extend horizontally. At this time, the position of the wire hole 131 is the lowest point of the first inner extension segment 53 and the first line segment 52, which can effectively prevent oil stains from flowing from the first inner extension segment 53 to the first line segment 52.

[0056] Of course, the first line segment 52 can also extend downwards. In this case, the oil stains on the first inner extension segment 53 can extend to the first line segment 52 and drip from the lowest point of the first line segment 52, reducing the oil stains from continuing to extend to the second inner extension segment 55.

[0057] To facilitate the fixing of the first inner extension section 53 and / or the second inner extension section 55, the first housing assembly 1 is connected to a first limiting structure 14, which is installed in the smoke collection chamber 17. The first limiting structure 14 is used to limit the position of the first inner extension section 53 and / or the second inner extension section 55 relative to the first housing assembly 1.

[0058] The first limiting structure 14 can be configured as one or multiple, and its number can be adjusted according to the length and extension path of the first inner extension section 53 and the second inner extension section 55 in the smoke collection chamber 17.

[0059] When multiple first limiting structures 14 are configured, the length of the first inner extension segment 53 or the second inner extension segment 55 located between any two first limiting structures 14 is locked, and the length of the first inner extension segment 53 or the second inner extension segment 55 is completely fixed. At this time, hooking the above extension segment will no longer cause displacement, thus avoiding the risk of safety regulations.

[0060] The first limiting structure 14 can be a claw with a recessed groove for engaging with the aforementioned extension section. Alternatively, the first limiting structure 14 can be a wire tie bridge with a hole formed between the wire tie bridge and the first housing assembly 1 for the extension section to pass through, thereby limiting the position of the extension section. In other words, the structure of the first limiting structure 14 is not limited to one type; any structure that can limit the position of the first inner extension section 53 and / or the second inner extension section 55 relative to the first housing assembly 1 is acceptable.

[0061] To facilitate the fixing of the outer extension section 54, the first housing assembly 1 is connected to a second limiting structure 12, which is used to limit the position of the outer extension section 54 relative to the first housing assembly 1.

[0062] In the above embodiments, the position of the outer extension 54 is restricted by the second limiting structure 12, and the outer extension 54 is not easily hooked. In particular, when there are multiple second limiting structures 12, the length of the outer extension 54 located between any two second limiting structures 12 is locked, which can prevent the outer extension 54 from being displaced relative to the first housing assembly 1 and avoid the risk of safety regulations.

[0063] Of course, the second limiting structure 12 can be configured as one or more, and its number can be adjusted according to the length of the outer extension segment 54 and the extension path.

[0064] The specific structure of the second limiting structure 12 is similar to that of the first limiting structure 14, so it will not be described in detail here.

[0065] In alternative implementations, such as Figures 5 to 7 As shown, the range hood also includes a fixing plate 2, which is connected to the first housing assembly 1 and forms a wiring cavity 4 between the fixing plate 2 and the first housing assembly 1. The outer extension section 54 is located inside the wiring cavity 4.

[0066] In the above embodiments, such as Figures 5 to 7 As shown, a wiring cavity 4 is formed between the fixing plate 2 and the first housing assembly 1. The outer extension section 54 can be connected to the lamp body 3 after being laid in the wiring cavity 4. The outer extension section 54 can be hidden in the wiring cavity 4. The outer extension section 54 is not visible on the appearance of the self-suction range hood. The outer extension section 54 will not be hooked, avoiding safety issues. In addition, the wiring cavity 4 can isolate the front oil stains, preventing the front oil stains from adhering to the outer extension section 54.

[0067] Based on the above embodiment, the fixing plate 2 and the first housing assembly 1 restrict the lamp connection wire 5, i.e., the outer extension section 54, located outside the smoke collection cavity 17, within the wiring cavity 4 along a direction perpendicular to the plane where the fixing plate 2 is located. In the above embodiment, the fixing plate 2, along a direction perpendicular to its own plane, can cooperate with the first housing assembly 1 to limit the outer extension section 54, thus limiting the outer extension section 54 while ensuring that the fixing plate 2 is installed more stably.

[0068] Specifically, the distance between the fixing plate 2 and the first housing assembly 1 can be greater than the maximum diameter of the outer extension 54, so that the fixing plate 2 will not squeeze the outer extension 54 when it is installed, ensuring that the fixing plate 2 is installed stably. The distance between the fixing plate 2 and the first housing assembly 1 can also be equal to the maximum diameter of the outer extension 54. This not only makes the position of the outer extension 54 more stable in the wiring cavity 4, but also minimizes the depth of the wiring cavity 4, increases the capacity of the inner cavity of the first housing assembly 1, and makes it difficult for oil stains at the wire hole 131 to flow down the first inner extension 53 to the first wire segment 52.

[0069] In an optional embodiment, the outer surface of the first housing assembly 1 is recessed with a mounting groove 13, and a wiring cavity 4 is formed between the mounting groove 13 and the fixing plate 2. The mounting groove 13 is provided with a wire through hole 131 and a wiring hole 132. The lamp connection wire 5, that is, the outer extension section 54 located outside the smoke collection cavity 17, can extend into the smoke collection cavity 17 through the wiring hole 132.

[0070] In the above embodiment, the outer surface of the first housing component 1 is recessed with a mounting groove 13, which not only provides a space for the outer extension section 54 and facilitates the installation of the outer extension section 54, but also increases the overall strength of the first housing component 1 at this point, making the fixing plate 2 fit the first housing component 1 more closely.

[0071] Specifically, the outer surface of the first housing assembly 1 is the front surface of the first housing assembly 1 facing the user.

[0072] In addition, if oil stains crawl from the inner surface of the first housing assembly 1 through the wire hole 131 and enter the outer surface of the wiring cavity 4 formed by the first housing assembly 1, the oil stains will be guided downward along the edge of the mounting groove 13 because the outer surface of the first housing assembly 1 is recessed with a mounting groove 13, and will not affect the area where the lamp body 3 is installed.

[0073] In alternative implementations, such as Figure 8 As shown, a lampshade 7 is provided inside the smoke collection chamber 17, and an oil-proof cavity is formed between the lampshade 7 and the first housing assembly 1.

[0074] The wiring hole 132 and the second inner extension section 55 can both be located inside the oil-proof cavity. The oil-proof cavity can prevent the oil fumes in the smoke collection cavity 17 from directly contacting the second inner extension section 55, and at the same time prevent the smoke collection cavity 17 from communicating with the wiring cavity 4 through the wiring hole 132, thereby preventing a large amount of oil stains from condensing on the second inner extension section 55 and the outer extension section 54, and preventing the oil stains from flowing along the second inner extension section 55 to the lamp body 3.

[0075] Alternatively, the wiring hole 132 may be located outside the oil-proof cavity, and the second inner extension 55 may extend into the oil-proof cavity from the wiring hole 132. The portion of the second inner extension 55 located outside the oil-proof cavity may have a downward-curved section. The curved section allows oil stains on the second inner extension 55 located outside the oil-proof cavity to drip off from the lowest point of the curved section, reducing the amount of oil stains that extend into the second inner extension 55 inside the lampshade 7.

[0076] In an optional embodiment, the range hood further includes a connector that is connected to the oil-proof cavity or to the outer wall of the smoke collection cavity 17.

[0077] In the above embodiments, whether the connector is connected to the oil-proof cavity or to the outer wall of the smoke collection cavity 17, it can effectively prevent the connector from directly contacting the oil fumes in the smoke collection cavity 17, thereby reducing the risk of the connector being contaminated by oil.

[0078] In an optional embodiment, one end of the lampshade 7 faces the wiring cavity 4 in a direction perpendicular to the plane of the fixing plate 2 and is connected to the first housing assembly 1 through a connector. The connector can be a screw or the like. Since the connector can extend from the wiring cavity 4 into the first housing assembly 1 and connect to the lampshade 7, the wiring cavity 4 can also hide the connector.

[0079] Based on this, since the other end of the lampshade 7 faces the lamp body 3 in a direction perpendicular to the plane of the fixing plate 2, if this end is connected to the first housing assembly 1 via a connector, one end of the connector will be located on the air inlet plate 11 on the front of the first housing assembly 1, which is not conducive to the aesthetics of the range hood. Therefore, in the optional embodiment, such as Figure 9 and Figure 10 As shown, the other end of the lampshade 7 has a wing plate 71, and the side of the wing plate 71 facing the inner surface of the first housing assembly 1 is recessed with a glue-applying groove 711 for receiving the glue.

[0080] When installing lampshade 7, such as Figure 10 As shown, the top of the lampshade 7 can be fixed with two screws, and glue is applied into the glue groove 711 at the other end. The bottom of the lampshade 7 is fixed by applying glue to prevent uneven force on the bottom of the lampshade 7 caused by fixing only one end of the lampshade 7, which would cause it to lift up. At the same time, it prevents gaps from forming around the lampshade 7, which would allow oil to enter the lampshade 7.

[0081] In alternative implementations, such as Figure 7 and Figure 9 As shown, the range hood also includes a second housing assembly 8 connected to the first housing assembly 1; the second housing assembly 8 communicates with the smoke collection chamber 17 of the first housing assembly 1 and forms a smoke extraction chamber 9 with the smoke collection chamber 17, and the second housing assembly 8 has a wire passage channel 81 set independently of the smoke extraction chamber 9; the first housing assembly 1 has a wire passage hole group communicating with the wire passage channel 81, and the wire passage hole group communicating with the inner cavity of the first housing assembly 1.

[0082] When using, such as Figure 9 As shown, the lamp connection wire 5 can be connected to the power supply on the power board 83 in the second housing assembly 8, then enter the wire passage 81 and pass through the wire hole group to enter the inner cavity of the first housing assembly 1, and finally enter the wiring cavity 4 through the wire hole 131 along the inner cavity surface of the first housing assembly 1.

[0083] In the above embodiment, since the second housing assembly 8 has a wire passage 81 that is independently provided from the smoke chamber 9, the wire passage 81 can be used for the lamp connection wire 5 to pass through. This part of the lamp connection wire 5 can be isolated from the oil circuit environment of the whole machine, so that the upper part of the lamp connection wire 5 will not be contaminated by oil.

[0084] The second housing assembly 8 may include an upper housing and a maintenance plate 82 connected to the upper housing, such as Figure 9 As shown, a wire-passing groove 84 is recessed at the corner of the back of the upper housing, and a wire-passing channel 81 is formed between the maintenance plate 82 and the wire-passing groove 84.

[0085] In order to facilitate the passage of the lamp connection wire 5 through the wire passage 81, the maintenance board 82 and the upper housing can be detachably connected by screws or other connectors.

[0086] In alternative implementations, such as Figure 8 and Figure 11 As shown, the first housing assembly 1 includes a connecting plate 15 located at the top and a side baffle 16 located in the inner cavity. The wire passage hole group includes a first wire passage hole 151 opened on the connecting plate 15 and a second wire passage hole 161 opened on the side baffle 16.

[0087] After passing through the wire passage 81, the lamp connecting wire 5 extends to the first wire passage hole 151, enters the inner cavity of the first housing assembly 1, and then passes through the second wire passage hole 161. At this time, the lamp connecting wire 5 will be in the smoke chamber 9. Since the oil environment side of the air intake area is blocked by the side baffle 16, the blocked side will not be contaminated by oil. Therefore, the part of the lamp connecting wire 5 between the first wire passage hole 151 and the second wire passage hole 161 will also not be contaminated by oil.

[0088] The above-described embodiments can minimize the contact between the lamp connecting wire 5 and the smoke chamber 9, thereby reducing the impact of oil on the lamp body 3.

[0089] In summary, the above-described embodiments effectively reduce the oil contamination of the lamp body 3 and the lamp connecting wire 5 by designing the positions of the wire hole 131 and the wiring hole 132, the lamp cover 7, the wire passage 81, and the wire hole group.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
