In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] like Figures 1 to 6 As shown, this embodiment first provides a smoke collecting structure for collecting oil smoke generated when cooking in the kitchen. The smoke collecting structure includes a cover body 1 and an air guide plate assembly 2. The cover body 1 includes a main cover body 13 and side panels 14 connected to both sides of the main cover body 13 to form a smoke collecting chamber 11; the cover body 1 is provided with a smoke inlet 12 connected to the smoke collecting chamber 11, and the air guide plate assembly 2 guides the oil smoke into the smoke collecting chamber 11 through the smoke inlet 12. The air guide plate assembly 2 includes an air guide plate 21, a rotating member 22 and a fastener, and the air guide plate 21 is rotatably connected to the rotating member 22. By rotating, the air guide plate 21 can cover or open the smoke inlet 12. The fastener connects the rotating member 22 and the cover body 1 in the front-to-back direction so that the rotating member 22 can be detachably connected to the cover body 1. In this installation method along the front-to-back direction, the fasteners and the side panels 14 are not arranged vertically, and the fasteners can be locked from the front side of the cover body 1 to install the air guide plate assembly 2, thereby realizing front disassembly and assembly of the air guide plate assembly 2.

[0041] It should be noted that the fastener can be installed in the front-to-back direction at a variety of different angles, that is, relative to the plane where the side plate 14 is located, the axial extension direction of the fastener has a variety of settings in space, as long as the angle between the axial extension direction of the fastener and the side plate 14 of the cover body 1 is less than 90°, the fastener can be connected to the rotating member 22 in the front-to-back direction. Moreover, the fastener can be installed from front to back to connect the rotating member 22, or the rotating member 22 can be installed from front to back to connect the fastener.

[0042] like Figure 2As shown, the angle between the axial direction of the fastener and the side plate 14 of the cover body 1 is 0° for explanation. At this time, the axial direction of the fastener is parallel to the side plate 14. In actual installation, the air guide plate 21 and the rotating member 22 can be preassembled and installed from the front side of the cover body 1. The air guide plate 21 and the rotating member 22 are installed by locking the fasteners from the front. There is no need to reserve installation space on both sides of the cover body 1, which reduces the restriction on the kitchen space. Moreover, this front disassembly and assembly structure does not require the cooperation of multiple people, and can be operated by one person, which improves the convenience of disassembly and assembly and the ease of operation.

[0043] Of course, in other embodiments, the fasteners can also realize the installation of the air guide plate assembly 2 at other angles from the front side of the main cover body 13 along the front-to-back direction. For example, the angle between the fasteners and the side panel 14 is 15°, 30°, 45°, etc., not limited to the drawings of this embodiment.

[0044] Specifically, the structure of the fastener has various forms, so that the fastener can be installed from front to back to connect the rotating member 22, or the rotating member 22 can be installed from front to back to connect the fastener. In one embodiment, the fastener is a screw, and threaded holes are provided on the cover body 1 and the rotating member 22. The screw passes through the threaded hole of the rotating member 22 and the threaded hole of the cover body 1 from the front side of the main cover body 13 from front to back to connect the rotating member 22 and the cover body 1. Accordingly, when it is necessary to remove the air guide plate assembly 2, the screw can be removed from the front side of the main cover body 13.

[0045] It should be noted that, in order to make the air guide plate 21 rotate more smoothly, a rotating shaft 211 is provided on both sides of the air guide plate 21, and a rotating member 22 is rotatably connected to the corresponding rotating shaft 211 on both sides of the air guide plate 21.

[0046] In another embodiment, the fastener includes a screw and a nut, one end of the screw is disposed on the cover body 1, a through hole is provided on the rotating member 22, the screw extends in the front-to-back direction, and the preassembled air guide plate 21 and the rotating member 22 are abutted against the cover body 1 from the front side of the main cover body 13. At this time, the rotating member 22 can be hung on the screw in the front-to-back direction through the through hole. The screw passes through the through hole of the rotating member 22 and is threadedly connected to the nut, and the connection between the rotating member 22 and the cover body 1 can be achieved by locking the nut from the front side of the main cover body 13.

[0047] The air guide plate assembly 2 also includes a reinforcing plate 24, which is detachably connected to the air guide plate 21 and is disposed on the side of the air guide plate 21 facing the smoke inlet 12. Since the air guide plate 21 is relatively thin, and in some embodiments, the air guide plate 21 is made of glass, the structural strength of the air guide plate 21 can be increased by the provision of the reinforcing plate 24, and the rotatable connection between the air guide plate 21 and the rotating member 22 can be easily achieved by the provision of the reinforcing plate 24. Specifically, one of the reinforcing plate 24 and the rotating member 22 has a rotating shaft 211, and the other has a rotating shaft hole 241, and the rotating shaft 211 is rotatably inserted into the rotating shaft hole 241. Figure 2 As shown, the reinforcing plate 24 has a sleeve 242 , a shaft hole 241 is formed in the sleeve 242 , and a protruding shaft 211 is provided on the rotating member 22 , and the shaft 211 can be inserted into the shaft hole 241 .

[0048] Of course, in other embodiments, the rotating shaft 211 can also be fixed on the reinforcing plate 24, and a concave rotating shaft hole 241 can be opened on the rotating member 22, so as to realize a rotatable connection between the air guide plate 21 and the rotating member 22, thereby facilitating the pre-assembly of the air guide plate 21 and the rotating member 22.

[0049] In order to improve the reliability of the installation of the air guide plate assembly 2, as Figure 7 and Figure 8 As shown, a mounting member 23 is provided in the housing 1, and the mounting member 23 is a block structure. The mounting member 23 is detachably connected to the main housing 13 or the side plate 14, and the mounting member 23 is used to connect the fastener. When the fastener includes a screw and a nut, the screw can be integrally provided with the mounting member 23 and pre-installed in the housing 1 in advance; when the fastener is a screw, a threaded hole is provided on the mounting member 23, and the screw is threadedly connected to the rotating member 22 and the mounting member 23 in sequence.

[0050] In another embodiment, the housing 1 has a front mounting plate 15, such as Figure 2 As shown, the front mounting plate 15 is arranged perpendicular to the horizontal plane. The rotating member 22 is attached to the front mounting plate 15. Figure 4 and Figure 6 The front mounting plate 15 is connected to the fastener. The front mounting plate 15 provides a mounting reference for the rotating member 22 and improves the mounting strength.

[0051] It should be noted that when the front mounting plate 15 has a certain thickness, it can provide sufficient support strength for the air deflector assembly 2, and the air deflector assembly 2 can be installed only through the front mounting plate 15 of the cover body 1. Alternatively, in other embodiments, the smoke collecting structure has both the mounting member 23 and the front mounting plate 15, and the air deflector assembly 2 is installed through the mounting member 23 and the front mounting plate 15, so that the structural strength is better. Specifically, the front mounting plate 15 can be sandwiched between the rotating member 22 and the mounting member 23. The fastener runs through the front mounting plate 15 and the rotating member 22 at the same time. In this way, the connection between the rotating member 22, the mounting member 23 and the front mounting plate 15 can be achieved through one fastener, and there is no need to set additional connecting members for the mounting member 23 and the front mounting plate 15.

[0052] The front mounting plate 15 can be formed in a variety of structural ways. The front mounting plate 15 can be formed integrally with the side plate 14 or integrally with the main cover body 13. In one embodiment, the front end of the side plate 14 is folded inwardly toward the smoke collecting chamber 11 to form the front mounting plate 15, and the front mounting plate 15 can increase the structural strength of the side plate 14. The mounting member 23 is detachably connected to the side plate 14, and the fasteners sequentially connect the rotating member 22, the front mounting plate 15 and the mounting member 23. In this way, the force applied by the air guide plate assembly 2 to the mounting member 23 can be dispersed to the side plate 14 and the front mounting plate 15, thereby reducing the risk of deformation of the side plate 14.

[0053] In order to increase the connection strength between the main cover body 13 and the side plate 14 and reduce the connection gap, the main cover body 13 has a front end plate 131, the front end plate 131 is attached to the front mounting plate 15, and the front mounting plate 15 is detachably connected to the front end plate 131. Figure 6 Specifically, the front mounting plate 15 and the front end plate 131 can be connected by a plurality of screws, so that the assembly and disassembly are convenient. In this way, the front mounting plate 15 can distribute the force it bears to the front end plate 131, further reducing the risk of deformation of the side plate 14.

[0054] In one embodiment, the rotating member 22 includes a first connecting portion 221 and a first supporting portion 222. The first connecting portion 221 is attached to the front mounting plate 15, and the first supporting portion 222 passes through the front mounting plate 15 to extend toward the inside of the housing 1. The first supporting portion 222 is slightly larger in size and is used to set the rotating shaft 211. In this way, the first connecting portion 221 and the first supporting portion 222 are arranged in an L shape, and the structural stability is also good.

[0055] In order to increase the reliability of the connection between the rotating member 22 and the mounting member 23, the mounting member 23 includes a second connecting portion 231 and a second supporting portion 232. The second connecting portion 231 and the second supporting portion 232 are arranged in an L shape to form an accommodating space 233. Figure 8As shown. The second connection portion 231 is convenient to fit the inner side of the front mounting plate 15 to connect with the first connection portion 221, and the first support portion 222 is located in the accommodating space 233 to fit and connect with the second support portion 232. At least two threaded holes are respectively provided on the mounting member 23 and the rotating member 22, that is, the threaded hole of the first connection portion 221 corresponds to the threaded hole of the second connection portion 231, and the threaded hole of the first support portion 222 corresponds to the threaded hole of the second support portion 232. In this way, at least two fasteners are used to connect the rotating member 22 and the mounting member 23.

[0056] In addition, the second support portion 232 is provided with a plurality of mounting holes 2321. Figure 8 The mounting member 23 is installed in the side plate 14 by using a fixing member such as a screw through the mounting hole 2321 .

[0057] In one embodiment, the front mounting plate 15 has a mounting groove 151 which is concave, and at least part of the rotating member 22 is accommodated in the mounting groove 151. The smoke collecting structure further includes a front decorative plate 3, which is attached to the front mounting plate 15 to cover the rotating member 22. Figure 7 and Figure 8 As shown, the first connection portion 221 can be accommodated in the mounting groove 151, and the first support portion 222 passes through the front mounting plate 15 to extend toward the housing 1. Preferably, the first connection portion 221 does not protrude from the plane where the front mounting plate 15 is located, and the front decorative plate 3 can fit the front mounting plate 15 to cover the rotating member 22, so that the range hood has a more neat and beautiful appearance. The front decorative plate 3 can be used as a decorative plate or an operation display screen, and this embodiment does not make any specific restrictions.

[0058] In one embodiment, the cover body 1 is provided with a plurality of buffer protrusions 4, such as Figures 2 to 5 As shown; the buffer protrusion 4 protrudes toward the side away from the smoke collecting chamber 11, and when the air guide plate 21 rotates to cover the smoke inlet 12, the air guide plate 21 abuts against the buffer protrusion 4. On the one hand, the buffer protrusion 4 can provide a buffer to prevent the air guide plate 21 from hitting the cover body 1; on the other hand, since the back of the air guide plate 21 is attached with a reinforcing plate 24, the buffer protrusion 4 can provide support for the area on the air guide plate 21 where the reinforcing plate 24 is not provided, thereby preventing the air guide plate 21 from being pressed and damaged.

[0059] Specifically, a buffer hole can be opened on the cover body 1, and a plug 41 made of a flexible material such as rubber is clamped in the buffer hole so that its end protrudes from the outside of the cover body 1 to form a buffer protrusion 4. This embodiment does not limit the setting position of the buffer protrusion 4, which can be adjusted as needed. As an example, Figure 4 As shown, since the reinforcing plate 24 contacts both sides of the cover body 1 , the buffer protrusion 4 is arranged in the middle of the cover body 1 .

[0060] The embodiment of the utility model also provides a range hood, which includes the above-mentioned smoke collection structure. With the above-mentioned smoke collection structure, the fastener and the side plate 14 of the range hood are not arranged vertically, and the fastener can be locked from the front side of the cover body 1 to install the air guide plate assembly 2 on the cover body 1, so that the air guide plate assembly 2 can be disassembled from the front, and there is no need to reserve installation space on both sides of the cover body 1, thereby reducing the restriction on the kitchen space. Moreover, this front disassembly and assembly structure does not require the cooperation of multiple people, and can be operated by one person, thereby improving the convenience of disassembly and assembly and the ease of maintenance of the range hood.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
