Description

Technical Field

[0001] Embodiments of the present invention relate to the field of household appliances, and more specifically to a range hood having a reversible smoke guide plate. Background Technology

[0002] Currently, an increasing number of range hoods on the market feature moving mechanisms, such as openable smoke guides that function as smoke deflectors. The control panel is typically mounted on these smoke guides and rotates integrally with them. Usually, the control panel and the main circuit board inside the range hood are electrically and / or communicatively connected via a wiring harness. To ensure a reliable wiring connection between the main circuit board and the control panel during the movement of the smoke guide, the wiring harness needs a predetermined redundant length to compensate for the displacement of the control panel as it moves with the smoke guide. If this redundant wiring harness is not properly arranged, it may affect the movement of the smoke guide, or be directly exposed when the smoke guide is open, making it susceptible to corrosion from grease and smoke, leading to various safety hazards. It also affects the overall appearance of the range hood, thus impacting the user experience. Furthermore, because the rotation of the smoke guide needs to be accommodated, the existing structures for arranging this redundant wiring harness are often complex, cumbersome to manufacture and / or assemble, and detrimental to future maintenance. Summary of the Invention

[0003] The purpose of embodiments of the present invention is to provide a range hood. At least one embodiment of the present invention can at least partially overcome the shortcomings of the prior art, enabling proper arrangement and protection of the wiring harness extending between the main body of the range hood and the smoke guide plate, while maintaining a clean appearance of the range hood without affecting the movement of the smoke guide plate.

[0062] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the scope of protection of the present invention. It should be noted that the directional terms used in the description refer to the conventional use of the stacked mounting assembly for the garment handling device, for ease of description, and should not be construed as absolute limitations on the corresponding features.

[0063] Figures 1 to 3 as well as Figures 5A to 5C A range hood 100 or a portion thereof according to an embodiment of the present invention is illustrated schematically in different views. Figure 1 and Figure 2 As shown, a range hood 100 according to an embodiment of the present invention includes a main cavity 1, a smoke guide plate 2, a drive device 3, a transmission connection structure 4, and a wire cover 5.

[0064] The main body of the range hood 100 is substantially housed within the main cavity 1, which includes, for example, a main circuit board (not shown). The smoke guide plate 2 is movably mounted within the main cavity 1. Figure 1 The example shown is mounted at a lower edge (lower edge of the user-facing front surface) of the main cavity 1, but other suitable designs are also possible. The drive unit 3, adapted to provide a driving action, is integrally housed within the main cavity 1, thus... Figure 1 The smoke guide plate 2 shown is not exposed to the outside and is not visible when it is flipped open. The smoke guide plate 2 can rotate relative to the main cavity 1 by means of the drive device 3 and the transmission connection structure 4 that drives the smoke guide plate 2 to the drive device 3, thereby having a fully flipped open working position. Figure 1 , Figure 5C ) and the standby position after flipping back ( Figure 5A ).

[0065] A control panel 6 is installed on the back of the range hood 100, facing away from the user, when the smoke guide plate 2 is in the working position. The display interface of the control panel 6 is shown to the user from the front of the smoke guide plate 2 through a transparent area, such as glass, on the smoke guide plate 2, allowing the user to perform various control operations on the range hood 100. The control panel 6 is electrically and / or communicatively connected to the main circuit board inside the main cavity 1 via a wiring harness. The wire cover 5 is used to hide and substantially fix the section of the wiring harness that crosses the section between the smoke guide plate 2 and the main cavity 1, especially the redundant section reserved to offset the displacement of the control panel 6 caused by the movement of the smoke guide plate 2, so as to prevent the exposed wiring harness from affecting the flipping movement of the smoke guide plate 2 or being contaminated or corroded, and to keep the appearance of the range hood 100 clean.

[0066] Specifically, the wire cover 5 is a separate component, configured to be detachably fitted onto the transmission connection structure 4 and to accommodate the wire harness. This simplifies the construction and assembly of both the transmission connection structure 4 and the wire cover 5, and facilitates the removal of the wire cover 5 and maintenance related to the wire harness. More preferably, the wire cover 5 is adapted to be installed and held on the transmission connection structure 4 in a manner that holds the wire harness along the transmission connection structure 4, thereby facilitating easier concealment, fixation, and maintenance of the wire harness, and resulting in a cleaner appearance of the range hood 100 after the smoke guide plate 2 is flipped open.

[0067] In a preferred exemplary embodiment, such as Figure 2 and Figure 3 As shown, the transmission connection structure 4 includes a fixed bracket 41 and a transmission link 42. The fixed bracket 41 is fixed to the smoke guide plate 2, particularly the back of the smoke guide plate 2. One end of the transmission link 42 is fixedly connected to the output end 31 of the drive device 3, and the other end of the transmission link 42 is fixedly connected to the fixed bracket 41. With this configuration of the transmission connection structure 4, the rotational movement of the output end 31 of the drive device 3 drives the transmission link 42, together with the fixed bracket 41 fixedly connected thereto, to rotate, thereby causing the smoke guide plate 2 fixedly connected to the fixed bracket 41 to rotate. Preferably, the wire cover 5 is detachably fitted onto the transmission link 42 and accommodates and holds the wire harness extending along at least a portion of the transmission link 42.

[0068] In a further preferred exemplary embodiment, such as Figure 2 As shown, the transmission link 42 of the transmission connection structure 4 has a drive arm section 421 fixedly connected to the output end 31 of the drive device 3, a fixed arm section 423 fixedly connected to the fixed bracket 41, and a connecting arm section 422 integrally connecting the drive arm section 421 and the fixed arm section 423. The wire cover 5 is at least detachably sleeved on the connecting arm section 422 to accommodate and hold the wire harness as it extends along the connecting arm section 422.

[0069] In a preferred exemplary embodiment, such as Figure 4A and Figure 4BAs shown, the cover 5 has a first cover body 51 and a second cover body 52 that can be interlocked. On at least a portion of one side of the cover 5, the first cover body 51 and the second cover body 52 are connected by a hinge 53, allowing them to pivot relative to each other about a pivot axis extending through the hinge 53. On the opposite side of the cover 5, the first cover body 51 and the second cover body 52 are respectively provided with a pair of interlocking latches, namely a male latch 54 and a female latch 55. The latch between the male latch 54 and the female latch 55 is releasable, so that the first cover body 51 and the second cover body 52 can be releasably locked together by the releasably interlocking male latch 54 and female latch 55. The figure only shows a pair of male latches 54 and female latches 55 as an example. It is understood that the number of latch pairs is not limited to one pair, but can be set in multiple pairs as needed, and the positions of male latches 54 and female latches 55 can be interchanged, as long as the first cover 51 and the second cover 52 can be releasably engaged with each other. Thus, the wire cover 5 can be sleeved on the transmission link 42, especially the connecting arm segment 422, through the engagement between the first cover 51 and the second cover 52, and at the same time, a wiring channel suitable for accommodating the wire harness is formed around the transmission link 42, especially the connecting arm segment 422. In other words, when the wire cover 5 is sleeved on the transmission link 42 and accommodates the wire harness, the wire harness and a part of the transmission link 42 are together accommodated in the wiring channel of the wire cover 5.

[0070] Preferably, the wire cover 5, or at least the wiring channel of the wire cover 5, is formed with a main dimension shape corresponding to at least a portion of the main dimension shape of the transmission link 42, so that it can be easily fitted onto the transmission link 42 and the wire harness can be easily accommodated and held along at least a portion of the transmission link 42.

[0071] For example, such as Figure 2 , Figure 3 As shown, the connecting arm segment 422 is formed in an arc shape, and its connection with the driving arm segment 421 and the fixed arm segment 423 both have corners. Accordingly, as Figure 3 , Figure 4A and Figure 4B As shown, the first cover 51 and the second cover 52 are respectively formed with arcuate main dimension shapes corresponding to the main dimension shape of the connecting arm segment 422, so that the wire cover 5 after the two are fastened together has a main dimension shape corresponding to a part of the transmission link 42, especially to the connecting arm segment 422. Of course, according to design requirements, the wire cover 5 can have other desired shapes, and its wiring channel for accommodating the wire harness is formed with a main dimension shape corresponding to at least a part of the transmission link 42, which can also achieve the above-mentioned effects of easy fitting and easy holding of the wire harness. In addition, the connecting arm segment 422 can of course be formed into any other suitable shape.

[0072] Preferably, when the wire cover 5 is fitted onto the transmission link 42, the wire cover 5 or its wiring channel also extends continuously to partially cover the drive arm segment 421 and / or the fixed arm segment 423.

[0073] In a preferred exemplary embodiment, such as Figures 3 to 4B As shown, when the wire cover 5 is fitted onto the transmission link 42, it extends continuously to at least cover the corner-shaped connection between the drive arm segment 421 and the connecting arm segment 422. Specifically, the transmission link 42 is designed such that at each position of the flipping movement of the smoke guide plate 2, its drive arm segment 421 is integrally housed within the main cavity 1, just like the drive device 3. Therefore, by making the wire cover 5 or its wiring channel continuously extend to cover the corner-shaped connection between the drive arm segment 421 and the connecting arm segment 422, the section of the wire harness leaving the wire cover 5 and entering the main cavity 1 can always be hidden within the main cavity 1 without being exposed. This ensures that the redundant section of the wire harness is always covered by the wire cover 5 and is not exposed at any position of the flipping movement of the smoke guide plate 2. Furthermore, with this structure, since the wire harness exits from the wire cover 5 closer to the output end 31 of the drive device 3, it is not necessary to leave a large amount of redundant length to offset the displacement caused by rotation. Therefore, the wiring arrangement of the wire harness within the main cavity 1 can be made more convenient and concise.

[0074] Alternatively or additionally, when the wire cover 5 is fitted onto the transmission link 42, the wire cover 5 or its wiring channel also extends continuously to cover the fixed arm segment 423. For example... Figure 3 As shown, the fixed arm segment 423 is fixed to the fixed bracket 41, so a portion of it is already covered by the fixed bracket 41 due to its connection and contact with the fixed bracket 41, while the portion that is not in contact with the fixed bracket 41 can be covered by the wire cover 5, especially its wiring channel. With this construction of the wire cover 5, the wiring harness can be held along a longer length of the transmission link 42, further ensuring the clean appearance of the range hood 100.

[0075] In a preferred exemplary embodiment, to further ensure protection of the wiring harness and a neat appearance of the range hood 100, such as Figure 1 , Figure 2 As shown, the range hood 100 also includes a guide channel 7 fixed to the smoke guide plate 2. This guide channel 7 is arranged between the control panel 6 and the transmission connection structure 4, and is configured to fix and guide the wiring harness along the smoke guide plate 2, specifically guiding it to the fixing bracket 41 or the wire cover 5. In this way, the wiring harness leading from the control panel 6 reaches the transmission connection structure 4 via the guide channel 7 and subsequently enters the wire cover 5, thus minimizing the exposure of the wiring harness.

[0076] In a preferred exemplary embodiment, the range hood 100 further includes at least one driven connection structure 8, which is configured to movably connect the smoke guide plate 2 to the main cavity 1 to assist in performing the flipping movement of the smoke guide plate 2. Figure 2 As shown, the driven connection structure 8 is similar in construction to the transmission connection structure 4, also including a fixed bracket 81 fixed to the back of the smoke guide plate 2 and a transmission link 82 fixedly connected to the fixed bracket 81. The difference lies in the construction of the transmission link 82. Specifically, the transmission link 82 has a hinged arm segment 821 hinged to a fixed seat 9 fixed in the main cavity 1, and a connecting arm segment 822 integrally connected to the hinged arm segment 821 and fixedly connected to the fixed bracket 81. The connecting arm segment 822 is preferably formed with the same main dimension shape as the connecting arm segment 422, so that the flipping movement of the smoke guide plate 2 is balanced and stable. Only one driven connection structure 8 is shown in the figure; however, those skilled in the art will understand that multiple driven connection structures 8 can be provided at multiple locations as needed.

[0077] Figures 5A to 5C The diagrams schematically illustrate three flip positions of the smoke guide plate 2 of the range hood 100 according to an embodiment of the present invention, viewed from the side of the transmission connection structure 4, relative to the drive unit 3 (main cavity 1). As described above, wherein... Figure 5A The image shows the standby position of the smoke guide plate 2 when it is flipped back. The front of the smoke guide plate 2 is shown at this time. Figure 5A The bottom surface of the main cavity 1 (not shown) is generally located within or near the bottom plane containing the lower edges of the main cavity 1 (not shown); Figure 1 Corresponding to the illustration, Figure 5C The smoke guide plate 2 is shown in its fully flipped-open working position. At this time, the front of the smoke guide plate 2 faces the user. The drive arm section 421 of the transmission connection structure 4 and the hinge arm section 821 of the driven connection structure 8 are still located inside the main cavity 1, while each connecting arm section 422 and 822 is exposed outside the main cavity 1. Figure 5B This shows a flip position of the smoke guide plate 2 between the standby position and the working position. From Figures 5A to 5C As can be seen, since the wiring harness can be held by the cover 5 along the transmission connection structure 4, the wiring harness remains hidden throughout the entire flipping process of the smoke guide plate 2. Therefore, it does not affect the flipping movement of the smoke guide plate 2, is not easily contaminated or corroded by oil fumes, and does not affect the cleanliness of the range hood 100's appearance. Furthermore, after opening the smoke guide plate 2, the cover 5 can be easily removed as needed for maintenance and repair operations related to the wiring harness.

[0078] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the invention, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this disclosure are intended to be illustrative and not limiting, unless otherwise stated. In practice, multiple features may be combined with each other as needed and where technically feasible. Various substitutions, changes, and modifications are also conceived without departing from the spirit and scope of the invention.
