Description

Technical Field

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

[0002] Range hoods include light panel assemblies. During the installation of these assemblies, the switches and controllers within them need to be connected. However, since the controller needs to connect to other structures within the hood housing, the wiring harnesses for the controller and switches typically extend out of the hood housing, resulting in limited installation space between the light panel assembly and the housing. Existing technologies typically use retractable or spiral wires, which can extend and retract on their own, to facilitate installation on the outside of the housing while preventing excessively long wires from interfering with other structures of the range hood. However, retractable and spiral wires are expensive, leading to a higher overall cost for the range hood. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, the purpose of this application is to provide a connecting harness that does not require self-extension and a fixed structure for securing and storing the connecting harness, thereby reducing the cost of the connecting harness and consequently reducing the cost of the range hood.

[0004] To address the aforementioned issues, this application provides a range hood, comprising a housing, a controller, a connecting harness, a panel assembly, a switch assembly, and a wiring harness, wherein the length of the connecting harness is fixed.

[0005] The switch assembly and the wiring structure are fixed to the panel assembly, and the panel assembly is fixed to the outside of the housing;

[0006] The first end of the connecting wire harness passes through the fixed wire structure and is connected to the switch assembly; the second end of the connecting wire harness is connected to the controller; the controller is connected to at least one functional unit inside the housing.

[0007] The portion of the connecting wire harness located between the second end and the fixed wire structure is wound around the fixed wire structure.

[0008] In this embodiment of the application, the fixed wire structure is provided with a mounting hole, and the first end of the connecting wire harness passes through the mounting hole and is connected to the switch assembly;

[0009] The connecting wire harness is provided with a first snap-fit ​​structure, which is fixedly connected to the wire fixing structure; the size of the first snap-fit ​​structure is larger than the size of the mounting hole.

[0010] In this embodiment of the application, the length of the wire harness between the first end and the first snap-fit ​​structure is equal to the distance between the switch assembly and the fixed wire structure.

[0011] In this embodiment of the application, the connecting wire harness is further provided with a second snap-fit ​​structure, the second snap-fit ​​structure is spaced apart from the first snap-fit ​​structure, and the second snap-fit ​​structure is close to the first end of the connecting wire harness;

[0012] The second snap-fit ​​structure matches the mounting hole.

[0013] In this embodiment of the application, the first snap-fit ​​structure is provided with a first fixing hole, and the wire fixing structure is provided with a second fixing hole;

[0014] When the second snap-fit ​​structure can pass through the mounting hole, the first fixing hole and the second fixing hole are misaligned.

[0015] In this embodiment of the application, the wire fixing structure includes a fixing base and a fixing panel, and the mounting hole is disposed on the fixing panel;

[0016] The fixed base is fixedly connected to the panel assembly, and the fixed base is rotatably connected to the fixed panel.

[0017] In this embodiment, the spacing between the second snap-fit ​​structure and the first snap-fit ​​structure is equal to the thickness of the fixed panel.

[0018] In this embodiment of the application, the wire fixing structure includes foldable wall claws, and a portion of the connecting wire harness located between the second end and the wire fixing structure is wound around the wire fixing structure through the wall claws.

[0019] In this embodiment of the application, the range hood further includes a drive mechanism, which is communicatively connected to the controller and is used to drive the opening and closing of the panel assembly.

[0020] In this embodiment of the application, the range hood further includes a pressure wire pipe, one end of which is connected to the drive mechanism, and the other end of which is connected to the panel assembly;

[0021] The portion of the connecting wire harness located between the second end and the fixed wire structure is disposed inside the pressure tube.

[0022] Due to the above technical solution, the range hood described in this application has the following beneficial effects:

[0023] By setting up a fixed wiring structure, a fixed-length wiring harness can be used between the controller and the switch assembly. Specifically, when the wiring harness is in a long state, the controller and switch assembly are installed and connected, and the portion of the wiring harness located between the second end and the fixed wiring structure is wrapped around the fixed wiring structure, thereby achieving the closure of the wiring harness and avoiding any impact on other structures of the range hood. Furthermore, it eliminates the need to use wiring harnesses that need to be automatically extended or shortened, thus reducing the cost of the wiring harness and the range hood.

[0034] Combination Figure 1-2 This application describes a range hood provided in an embodiment. The range hood includes a housing 1, a controller 2, a connecting harness 3, a panel assembly 4, a switch assembly 5, and a wire fixing structure 6. The length of the connecting harness 3 is fixed. The switch assembly 5 and the wire fixing structure 6 are fixed to the panel assembly 4, and the panel assembly 4 is fixed to the outside of the housing 1. The first end of the connecting harness 3 passes through the wire fixing structure 6 and is connected to the switch assembly 5. The second end of the connecting harness 3 is connected to the controller 2. The controller 2 is connected to at least one functional unit inside the housing 1. The portion of the connecting harness 3 located between the second end and the wire fixing structure 6 is wound around the wire fixing structure 6.

[0035] In this embodiment, the wire-fixing structure 6 is used to gather the longer connecting wire harness 3 to avoid the excessively long connecting wire harness 3 affecting other structures of the range hood. The length of the connecting wire harness 3 is greater than the preset length. The preset length is determined based on the distance from the controller 2 to the switch assembly 5 in the range hood and the routing direction of the connecting wire harness 3 in the housing 1. Specifically, the length of the connecting wire harness 3 needs to ensure that the controller 2 can be connected to the switch assembly 5, while also leaving a certain length so that the connector and the switch panel can be installed before the panel assembly 4 is fixed to the housing 1, thus improving the ease of installation.

[0036] In specific embodiments of this application, the functional units include, but are not limited to, a lighting unit and a fan unit.

[0037] In this embodiment, by setting the fixed wire structure 6, a fixed-length connecting wire harness 3 can be used between the controller 2 and the switch assembly 5. Specifically, when the connecting wire harness 3 is in a longer state, the controller 2 and the switch assembly 5 are connected and the portion of the connecting wire harness 3 located between the second end and the fixed wire structure 6 is wrapped around the fixed wire structure 6, thereby achieving the closure of the connecting wire harness 3 and avoiding any impact on other structures of the range hood. Furthermore, it eliminates the need for a wire harness that needs to be automatically extended or shortened, thereby reducing the cost of the connecting wire harness 3 and the cost of the range hood.

[0038] In a specific embodiment of this application, the switch assembly 5 includes a switch connector to facilitate the connection of the wiring harness to the switch assembly.

[0039] refer to Figure 3-4 In this embodiment of the application, the fixed wire structure 6 is provided with a mounting hole 621, and the first end of the connecting wire harness 3 passes through the mounting hole 621 and is connected to the switch assembly 5; the connecting wire harness 3 is provided with a first snap-fit ​​structure 31, and the first snap-fit ​​structure 31 is fixedly connected to the fixed wire structure 6; the size of the first snap-fit ​​structure 31 is larger than the size of the mounting hole 621.

[0040] In this embodiment, the mounting hole 621 is used to fix the position of the connecting wire harness 3, and the first snap-fit ​​structure 31 is used to snap the connecting wire harness 3 to the wire fixing structure 6 to restrict the movement of the connecting wire harness 3 towards the first end; the size of the first snap-fit ​​structure 31 is larger than the size of the mounting hole 621, indicating that the first snap-fit ​​structure 31 cannot pass through the mounting hole 621; that is, in this application, after the first end of the connecting wire harness 3 passes through the mounting hole 621, the first snap-fit ​​structure 31 abuts against the wire fixing structure 6, thereby fixing the position of the wire fixing structure 6, and then fixing the abutting first snap-fit ​​structure 31 to the wire fixing structure 6.

[0041] In this embodiment of the application, by setting a first snap-fit ​​structure 31 on the connecting wire harness 3, the connecting wire harness 3 is prevented from passing through the mounting hole 621 without restriction, the length of the connecting wire harness 3 between the fixed wire structure 6 and the switch assembly 5 is limited, and the excessively long wire harness is prevented from affecting other structures inside the range hood. At the same time, it avoids the need for manual evaluation of whether the length of the connecting wire harness 3 between the fixed wire structure 6 and the switch assembly 5 is appropriate, and reduces the installation difficulty of the connecting wire harness 3 and the panel assembly 4.

[0042] In this embodiment, the length of the wire harness between the first end and the first snap-fit ​​structure 31 is equal to the distance between the switch assembly 5 and the fixed wire structure 6.

[0043] In this embodiment, the length of the wire harness between the first end and the first snap-fit ​​structure 31 is equal to the distance between the switch assembly 5 and the fixed wire structure 6, indicating that the connecting wire harness 3 between the switch assembly 5 and the fixed wire structure 6 is in a taut state.

[0044] In this embodiment, by setting the length of the wire harness between the first end and the first snap-fit ​​structure 31 to be equal to the distance between the switch assembly 5 and the fixed wire structure 6, the loose connecting wire harness 3 is prevented from being repositioned, thereby preventing the connecting wire harness 3 from affecting other structures.

[0045] In this embodiment of the application, the connecting wire harness 3 is further provided with a second snap-fit ​​structure 32, which is spaced apart from the first snap-fit ​​structure 31, and the second snap-fit ​​structure 32 is close to the first end of the connecting wire harness 3; the second snap-fit ​​structure 32 matches the mounting hole 621.

[0046] In this embodiment, the matching of the second snap-fit ​​structure 32 with the mounting hole 621 indicates that the second snap-fit ​​structure 32 can pass through the mounting hole 621.

[0047] In this embodiment, by providing a second snap-fit ​​structure 32, when the second snap-fit ​​structure 32 passes through the mounting hole 621, the second snap-fit ​​structure 32 abuts against the wire fixing structure 6 to restrict the movement of the connecting wire harness 3 towards the second end, thereby preventing the loose connecting wire harness 3 from being repositioned and thus preventing the connecting wire harness 3 from affecting other structures.

[0048] In this embodiment, the first snap-fit ​​structure 31 is provided with a first fixing hole 311, and the wire fixing structure 6 is provided with a second fixing hole 622; when the second snap-fit ​​structure 32 can pass through the mounting hole 621, the first fixing hole 311 and the second fixing hole 622 are misaligned.

[0049] In this embodiment, when the second snap-fit ​​structure 32 can pass through the mounting hole 621, the first snap-fit ​​structure 31 cannot be fixed to the wire-fixing structure 6; when the first snap-fit ​​structure 31 is fixedly connected to the wire-fixing structure 6 through the first fixing hole 311 and the second fixing hole 622, the second snap-fit ​​structure 32 cannot pass through the mounting hole 621, thus achieving the snap-fit ​​between the second snap-fit ​​structure 32 and the wire-fixing structure 6.

[0050] In this embodiment, by offsetting the first fixing hole 311 and the second fixing hole 622 when the second snap-fit ​​structure 32 can pass through the mounting hole 621, the first snap-fit ​​structure 31 and the wire fixing structure 6 can be fixedly connected by simply rotating the connecting wire harness 3, while the second snap-fit ​​structure 32 can also be snapped into the wire fixing structure 6, thereby improving the ease of structural installation.

[0051] In a specific embodiment of this application, the second snap-fit ​​structure 32 includes a main body and a snap-fit ​​part. The main body wraps around the connecting wire harness 3, and the snap-fit ​​part is located on the outside of the main body. The mounting hole 621 includes a main body hole and a snap-fit ​​hole. The main body hole matches the main body, and the snap-fit ​​hole matches the snap-fit ​​part. The snap-fit ​​between the second snap-fit ​​structure 32 and the wire fixing structure 6 is achieved by misaligning the snap-fit ​​part and the snap-fit ​​hole, which reduces the ease of installation.

[0052] In another specific embodiment of this application, the second snap-fit ​​structure 32 includes a main body and a snap-fit ​​receiving part, which is housed within the main body; the mounting hole 621 includes a main body hole that matches the main body; by providing the snap-fit ​​receiving part, the snap-fit ​​receiving part is released from the main body during installation, thereby achieving snap-fit ​​between the second snap-fit ​​structure 32 and the wire fixing structure 6, reducing installation convenience and improving installation flexibility.

[0053] refer to Figure 5 In this embodiment of the application, the wire fixing structure 6 includes a fixed base 61 and a fixed panel 62, and a mounting hole 621 is provided on the fixed panel 62; the fixed base 61 is fixedly connected to the panel assembly 4, and the fixed base 61 is rotatably connected to the fixed panel 62.

[0054] In this embodiment, by setting the fixed base 61 and the fixed panel 62 to be rotatably connected, the length of the connecting wire harness 3 between the first end and the fixed wire structure 6 can be adjusted by rotating the fixed base 61, thereby avoiding the impact of the production error of the first snap-fit ​​structure 31 on the installation and improving the installation flexibility of the connecting wire harness 3.

[0055] In this embodiment of the application, the second fixing hole 622 is disposed on the fixing panel 62, preferably, the second fixing hole 622 is disposed around the mounting hole 621.

[0056] In this embodiment, the gap between the second snap-fit ​​structure 32 and the first snap-fit ​​structure 31 is equal to the thickness of the fixed panel 62.

[0057] In this embodiment, by setting the gap between the second snap-fit ​​structure 32 and the first snap-fit ​​structure 31 to be equal to the thickness of the fixed panel 62, the first snap-fit ​​structure 31 can restrict the movement of the connecting wire harness 3 towards the first end, while the second snap-fit ​​structure 32 can also restrict the movement of the connecting wire harness 3 towards the second end, thereby achieving bidirectional constraint on the movement of the connecting wire harness 3, thus avoiding the connecting wire harness 3 from affecting other structures of the range hood.

[0058] In this embodiment of the application, the wire fixing structure 6 includes a foldable wall claw 623, and a portion of the connecting wire harness 3 located between the second end and the wire fixing structure 6 is wound around the wire fixing structure 6 through the wall claw 623.

[0059] In this embodiment of the application, by setting a foldable wall claw 623, the portion of the connecting wire harness 3 located between the second end and the fixed wire structure 6 can be wound around the fixed wire structure 6. At the same time, the wall claw 623 can be folded according to the actual situation, so as to realize the flexibility of winding the connecting wire harness 3 and improve the installation convenience of the connecting wire harness 3.

[0060] In a specific embodiment of this application, the wire fixing structure 6 may include one wall claw 623 or multiple wall claws 623, and the setting position of the wall claw 623 may be determined based on actual needs; preferably, the wire fixing structure 6 includes two wall claws 623, and the two wall claws 623 are respectively set on both sides of the fixing panel 62.

[0061] In this embodiment, the range hood further includes a drive mechanism 7, which is communicatively connected to the controller 2 and is used to drive the opening and closing of the panel assembly 4.

[0062] In this embodiment of the application, by setting the drive mechanism 7, the panel assembly 4 is opened and closed, which facilitates the subsequent cleaning and maintenance of the range hood.

[0063] In this embodiment, the range hood also includes a pressure pipe 8, one end of which is connected to the drive mechanism 7, and the other end of which is connected to the panel assembly 4; a portion of the connecting wire harness 3 located between the second end and the fixed wire structure 6 is disposed inside the pressure pipe 8.

[0064] In this embodiment of the application, by setting a wire clamping pipe 8 inside the range hood, the wire clamping pipe 8 is used to restrict the direction of the connecting wire harness 3 inside the housing 1, thereby avoiding the connecting wire harness 3 from affecting other structures inside the housing 1.

[0065] In a specific embodiment of this application, the drive mechanism 7 is rotatably connected to the pressure tube 8. The drive mechanism 7 is used to drive the pressure tube 8 to rotate relative to the drive mechanism 7, so as to realize the opening and closing of the panel assembly 4.

[0066] refer to Figure 6 In this embodiment of the application, the panel assembly 4 includes a glass back plate 41, a smoke-proof glass plate 42, a side plate 43, and a bottom plate; the switch assembly 5 is disposed on the smoke-proof glass plate 42, and the side plate 43 is used to close the panel space enclosed by the panel assembly 4.

[0067] In a specific embodiment of this application, the smoke-proof glass panel 42 is provided with a number of functional buttons, which are communicatively connected to the switch assembly.

[0068] The following describes the installation process of the range hood in the embodiments of this application:

[0069] Install the switch assembly 5 and the wiring structure 6 on the panel assembly 4. Then, pull the connecting wire harness 3 out from the housing 1. One end of the connecting wire harness 3 is already connected to the controller 2. After passing the first end of the connecting wire harness 3 through the wiring structure 6, connect it to the switch assembly 5. Then, fix it to the panel assembly 4 through the wire clamping tube 8 to connect the panel assembly 4 to the housing 1. Finally, wrap the part of the connecting wire harness 3 between the second end and the wiring structure 6 around the wiring structure 6, and use the side plate 43 to seal the side of the panel assembly 4 to complete the installation of the range hood.

[0070] The range hood in this embodiment has the following beneficial effects:

[0071] By setting up the fixed wiring structure 6, a fixed-length connecting wire harness 3 can be used between the controller 2 and the switch assembly 5. Specifically, when the connecting wire harness 3 is in a longer state, the controller 2 and the switch assembly 5 can be connected and installed. The part of the connecting wire harness 3 located between the second end and the fixed wiring structure 6 is wrapped around the fixed wiring structure 6, thereby achieving the closure of the connecting wire harness 3 and avoiding the connecting wire harness 3 from affecting other structures of the range hood. Moreover, it is not necessary to use a wire harness that needs to be stretched or shortened, thereby reducing the cost of the connecting wire harness 3 and the cost of the range hood.
