Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a smoke guide plate installation structure and a range hood. Background Technology

[0002] A range hood typically includes a housing and a smoke guide plate. The housing has a smoke collection chamber and a smoke inlet connected to the chamber. The smoke guide plate is installed on the housing and is used to open or close the smoke inlet. In existing technology, two outwardly protruding pivots are usually fixedly installed at both ends of the smoke guide plate, and the smoke guide plate is rotated and installed on both sides of the upper edge of the smoke inlet via the pivots. Although the above structure can realize the rotation of the smoke guide plate to open or close the smoke inlet, the disassembly and assembly of the smoke guide plate is not convenient, and because the smoke guide plate tends to accumulate a lot of grease during long-term use, it is also inconvenient to remove the smoke guide plate for cleaning.

[0003] To address this, some existing technologies incorporate a sliding block inside the smoke guide plate, fixing the rotating shaft to the block. This allows for the insertion or separation of the rotating shaft from the housing by moving the sliding block. While this structure facilitates the assembly and disassembly of the smoke guide plate, the operation of the fan during range hood use can easily cause vibrations in both the housing and the smoke guide plate. These vibrations can cause the sliding block to move, potentially leading to the rotating shaft detaching from the housing. In other words, the smoke guide plate's installation is not stable and carries a risk of accidental detachment. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a smoke guide plate installation structure that is stable to install and easy to disassemble.

[0041] Reference Figures 1 to 9 This utility model provides a smoke guide plate mounting structure, which includes a housing 100, a smoke guide plate 200, a mounting strip 300, and two sets of fastening components. The housing 100 has a smoke collection chamber 110, and a smoke inlet 120 communicating with the smoke collection chamber 110 is opened on the front side wall of the housing 100. Rotation holes 142 are opened on both the left and right sides of the smoke inlet 120. The smoke guide plate 200 is located on the front side of the housing 100 and can cover the smoke inlet 120. The mounting strip 300 is mounted on the upper edge of the smoke guide plate 200. Mounting holes 310 corresponding to the two rotation holes 142 are opened at both ends of the mounting strip 300, and fastening holes 320 communicating with the mounting holes 310 are opened on the inner surface of the mounting strip 300. Two sets of fastening components are respectively arranged on the left and right sides of the smoke guide plate 200. The fastening components include a rotating part 400 and a fastener 500. The rotating part 400 is rotatably installed in the rotating hole 142 and inserted into the mounting hole 310. The outer end of the rotating part 400 has an abutting part 420 that can abut against the outer periphery of the rotating hole 142. The rotating part 400 also has a limiting hole 410 corresponding to the fastening hole 320. The fastener 500 is installed in the fastening hole 320 and inserted into the limiting hole 410.

[0042] In the smoke guide plate mounting structure of this utility model embodiment, a mounting strip 300 is provided on the upper edge of the smoke guide plate 200, and the rotating connection between the smoke guide plate 200 and the housing 100 is realized by the mounting strip 300. Specifically, during installation, the two mounting holes 310 on the mounting strip 300 can be aligned with the two rotating holes 142 on the housing 100 one by one. Then, the rotating component 400 is inserted into the corresponding rotating holes 142 and mounting holes 310 in sequence, thus achieving the initial installation of the smoke guide plate 200. Then, the fastener 500 is installed into the fastening holes 320 on the mounting strip 300 and extends inward into the fastening holes 320 of the rotating component 400. The installation is relatively convenient, and the smoke guide plate installation structure can achieve a fixed connection between the rotating component 400 and the mounting strip 300 through the fastener 500. This structure can not only reduce the risk of the rotating component 400 coming off the mounting hole 310 of the mounting strip 300 due to vibration or collision during use, but also make the installation and operation of the smoke guide plate 200 more stable, which helps to reduce the risk of the smoke guide plate 200 accidentally falling off during use. Furthermore, the rotating component 400 has an abutment portion 420 that can abut against the outer periphery of the rotating component 400. The abutment portion 420 can cooperate with the fastener 500 to further improve the installation stability of the rotating component 400. When it is necessary to disassemble the smoke guide plate 200, simply remove the fastener 500 and the rotating component 400 in sequence. The operation is simple and convenient, thus facilitating the cleaning or maintenance of the smoke guide plate 200.

[0043] It is understood that in the smoke guide plate mounting structure of this utility model embodiment, by opening the fastening hole 320 on the inner surface of the mounting strip 300, specifically the inner surface of the mounting strip 300 near the housing 100, the fastener 500 is mounted on the side surface of the mounting strip 300 near the housing 100. This structure can hide the fastener 500, preventing the fastener 500 from affecting the appearance of the smoke guide plate 200, and also protect the fastener 500 from accidental disassembly.

[0044] Reference Figure 5 In some embodiments, a support frame 210 and a switch assembly 220 are also installed on the inner surface of the smoke guide plate 200. The support frame 210 is used to connect with the drive mechanism inside the smoke collection chamber 110, so that the smoke guide plate 200 can be flipped open and closed under the drive of the drive mechanism. The switch assembly 220 can be used to control the operation of the range hood.

[0045] Reference Figures 1 to 6 In some embodiments, a positioning groove 330 is provided on the lower side of the mounting strip 300, and the smoke guide plate 200 is inserted into the positioning groove 330. The inner surface of the smoke guide plate 200 is bonded to the rear inner wall of the positioning groove 330.

[0046] By adopting the above structure, during installation, the smoke guide plate 200 can be inserted into the positioning groove 330 of the mounting strip 300 first, and then the inner surface of the smoke guide plate 200 can be bonded to the rear inner wall of the positioning groove 330, making installation simple and convenient. The positioning groove 330 allows for positioning of the smoke guide plate 200 and the mounting strip 300 during installation, facilitating subsequent bonding of the smoke guide plate 200 to the rear inner wall of the positioning groove 330, thus ensuring a stable connection between the smoke guide plate 200 and the mounting strip 300. Furthermore, since the smoke guide plate 200 has a relatively large lateral dimension, it is prone to deformation under stress. By inserting the smoke guide plate 200 into the positioning groove 330, the positioning groove 330 can also correct the dimensions of the smoke guide plate 200, strengthening its structural strength and reducing the risk of deformation.

[0047] It is understood that the inner surface of the smoke guide plate 200 is bonded to the rear inner wall of the positioning groove 330. Specifically, the two can be bonded with glass glue. Of course, glue or other adhesive materials can also be used for bonding. This utility model does not make any specific limitation in this regard.

[0048] It is understood that the width of the positioning groove 330 can be set to 5mm. Of course, the width of the positioning groove 330 can also be set to other dimensions. This utility model does not make specific limitations on this, as long as the width of the positioning groove 330 can be adapted to the thickness of the smoke guide plate 200.

[0049] Reference Figures 1 to 6 In some embodiments, the height of the front inner wall of the positioning groove 330 is less than the height of the rear inner wall of the positioning groove 330.

[0050] In the above structure, since the inner surface of the smoke guide plate 200 is bonded to the rear inner wall of the positioning groove 330, by setting the height of the front inner wall of the positioning groove 330 to be less than the height of the rear inner wall of the positioning groove 330, that is, increasing the height of the rear inner wall of the positioning groove 330, it is possible not only to increase the bonding area between the smoke guide plate 200 and the mounting strip 300, making the installation between the two more secure and stable, but also to reduce the obstruction of the front side wall of the positioning groove 330 of the mounting strip 300 on the smoke guide plate 200, thereby improving the aesthetics of the front surface of the smoke guide plate 200.

[0051] In some embodiments, the smoke guide plate 200 is a glass panel and the mounting strip 300 is an aluminum strip.

[0052] In the above structure, by setting the smoke guide plate 200 as a glass panel, not only can the aesthetics of the smoke guide plate 200 be improved, but it can also be made easier to clean, reducing the difficulty of cleaning the smoke guide plate 200. In addition, by setting the mounting strip 300 as an aluminum strip, the installation strength of the smoke guide plate 200 can be improved, which in turn can improve the installation and operational stability of the smoke guide plate 200.

[0053] Reference Figures 1 to 6 In some embodiments, the upper end of the mounting strip 300 is provided with an arcuate surface 340 arranged circumferentially along the mounting hole 310, and the front sidewall of the housing 100 is also provided with a decorative plate 130. The decorative plate 130 is located at the upper end of the smoke inlet 120, and the lower end of the decorative plate 130 is provided with an arcuate groove 131 with an opening facing the mounting strip 300. The arcuate surface 340 and the inner wall of the arcuate groove 131 are spaced apart, and in the front-back direction, the arcuate groove 131 can cover at least part of the arcuate surface 340.

[0054] In the above structure, the curved surface 340 facilitates the flipping of the smoke guide plate 200, preventing collisions and interference between the mounting strip 300 and the housing 100 during the flipping process, thus protecting both the mounting strip 300 and the housing 100. Furthermore, by providing a decorative panel 130 with a curved groove 131 at its lower end, the curved surface 340 is partially obscured, improving the aesthetics of the front surface of the range hood and also protecting the mounting strip 300.

[0055] Reference Figures 1 to 7 In some embodiments, in each fastening assembly, the rotating member 400 has a rotating portion 430 and a plug portion 440. The rotating portion 430 is connected to the abutment portion 420, and the plug portion 440 is connected to the side of the rotating portion 430 away from the abutment portion 420. The rotating portion 430 is rotatably mounted in the rotating hole 142, and the plug portion 440 is inserted into the mounting hole 310. The cross-section of the plug portion 440 is non-circular, and the cross-sectional shape of the mounting hole 310 is adapted to the cross-sectional shape of the plug portion 440.

[0056] In the above structure, by providing a plug-in portion 440 and a rotating portion 430 on the rotating member 400, the plug-in portion 440 achieves a fixed connection with the mounting strip 300, and the rotating portion 430 achieves a rotatable connection with the rotating hole 142, thereby achieving a rotatable connection between the smoke guide plate 200 and the housing 100. By setting the cross-section of the plug-in portion 440 to be non-circular, it is easy to position and align the limiting hole 410 on the plug-in portion 440 with the fastening hole 320 on the mounting strip 300, making the installation of the rotating member 400 more convenient.

[0057] Reference Figures 1 to 7In some embodiments, the cross-section of the plug portion 440 is hexagonal.

[0058] In the above structure, by setting the cross-section of the plug portion 440 to a hexagon, it is not only convenient to position and align the limiting hole 410 on the plug portion 440 with the fastening hole 320 on the mounting strip 300, but also to reduce the gap between the plug portion 440 and the inner wall of the mounting hole 310, further reducing the risk of loosening between the plug portion 440 and the mounting strip 300.

[0059] Understandably, by setting the cross-section of the insertion part 440 to a hexagon, six planes are formed on the outer periphery of the insertion part 440, and the limiting hole 410 can be directly opened on one of the planes of the insertion part 440, thereby making the opening and processing of the limiting hole 410 more convenient and faster.

[0060] It is understood that the cross-section of the plug part 440 can be set as hexagonal, triangular, quadrilateral or other polygonal structure. In addition, the cross-section of the plug part 440 can also be set as elliptical or other non-circular. This utility model does not make specific limitations on this.

[0061] Reference Figures 1 to 7 In some embodiments, the fastener 500 is threaded to the inner wall of the fastening hole 320, thereby achieving a stable connection between the fastener 500 and the mounting strip 300, making the connection between the two more secure, reducing the risk of the fastener 500 coming out of the fastening hole 320, and thus confining the fastener 500 within the limiting hole 410 of the rotating member 400, making the connection between the rotating member 400 and the mounting strip 300 more secure and stable.

[0062] Reference Figures 1 to 7 In some embodiments, the fastener 500 is threaded to the inner wall of the limiting hole 410, thereby achieving a stable connection between the fastener 500 and the rotating member 400, making the connection between the two more robust. This confines the fastener 500 within the limiting hole 410 and the fastening hole 320, which helps reduce the risk of the fastener 500 coming out of the fastening hole 320 and the limiting hole 410, making the connection between the rotating member 400 and the mounting strip 300 more robust and stable.

[0063] It is understood that, in order to achieve a stable connection between the rotating part 400 and the mounting strip 300, the fastener 500 may be threaded only to the inner wall of the fastening hole 320 or only to the inner wall of the limiting hole 410. In addition, for a more stable and compact connection, the fastener 500 may be threaded to both the inner wall of the fastening hole 320 and the inner wall of the limiting hole 410, so that the fastener 500 is threadedly installed in both the fastening hole 320 and the limiting hole 410. This utility model does not make any specific limitation on this.

[0064] It is understood that fastener 500 can be a countersunk screw or other threaded parts, and this utility model does not make any specific limitation in this regard.

[0065] Reference Figures 1 to 9 In some embodiments, two fixing members 140 are installed in the smoke collection chamber 110. The two fixing members 140 are respectively arranged on the left and right sides of the smoke inlet 120. The fixing members 140 are provided with outwardly bent mounting ears 141. The mounting ears 141 pass through the housing 100 and extend to the outside of the smoke collection chamber 110. The rotating hole 142 is opened in the corresponding mounting ear 141.

[0066] By adopting the above structure, the rotating hole 142 is formed on a fixing member 140 that is independent of the housing 100, and the fixing member 140 is then installed inside the smoke collection chamber 110. This avoids directly machining the rotating hole 142 on the housing 100, making the machining of the rotating hole 142 more convenient. By fixing the fixing member 140 inside the smoke collection chamber 110, it is beneficial to protect the fixing member 140 and improve the aesthetics of the outer surface of the range hood. By bending the fixing member 140 outward to form the mounting ear 141, the machining of the rotating hole 142 can be facilitated, and the structural strength of the fixing member 140 can also be improved, thereby providing more stable support for the smoke guide plate 200.

[0067] An embodiment of this utility model also proposes a range hood, which is provided with the smoke guide plate mounting structure of any of the above embodiments.

[0068] In the range hood of this utility model embodiment, by setting the smoke guide plate mounting structure of any of the above embodiments, the smoke guide plate mounting structure realizes the rotatable connection between the smoke guide plate 200 and the housing 100 through the mounting strip 300. During installation, the two mounting holes 310 on the mounting strip 300 can be aligned one by one with the two rotating holes 142 on the housing 100. Then, the rotating part 400 is inserted into the corresponding rotating hole 142 and mounting hole 310 in sequence, thereby realizing the initial installation of the smoke guide plate 200. Then, the fastener 500 is installed into the fastening hole 320 on the mounting strip 300 and extends inward into the fastening hole 320 of the rotating part 400. The installation is relatively convenient, and the fastener 500 can realize the fixed connection between the rotating part 400 and the mounting strip 300, thereby reducing the risk of the smoke guide plate 200 accidentally falling off during the operation of the range hood, making the installation and operation of the smoke guide plate 200 more stable. In addition, when it is necessary to disassemble the smoke guide plate 200, simply remove the fastener 500 and the rotating part 400 in sequence. The operation is simple and convenient, thus making it easy to clean the range hood.

[0069] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
