It should be understood that these embodiments are only used to illustrate this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0056] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0058] This utility model provides a smoke inlet pipe assembly and a range hood for a range hood, which can solve the problem of easy oil leakage at the connection between the smoke inlet pipe assembly and the smoke collection hood, thereby improving the user experience.

[0059] Please refer to the following for comprehensive information. Figures 1 to 13 This application specification provides a smoke inlet pipe assembly for a range hood. The smoke inlet pipe assembly may include a smoke inlet pipe 3, which has a smoke inlet section 31 and a smoke outlet section. Along the direction of smoke flow, the smoke inlet section 31 is located upstream of the smoke outlet section. The smoke inlet section 31 is used to communicate with the smoke collection hood 4 of the range hood, and the smoke outlet section is used to communicate with the fan box 1 of the range hood. At least the inner surface of the smoke inlet section 31 is located inside the outlet of the smoke collection hood 4.

[0060] In this embodiment, the smoke inlet pipe assembly may include a smoke inlet pipe 3, which may be a hollow tube structure. The cross-section of the smoke inlet pipe 3 may be circular, rectangular, or other regular or irregular structures; this application does not impose specific limitations herein. The embodiments and accompanying drawings of this application (such as...) Figure 7 , Figure 8 and Figure 9 In the example, the cross-section of the smoke inlet pipe 3 is rectangular.

[0061] like Figure 3 As shown, the smoke inlet pipe 3 has opposing inlet and outlet ends. Near the inlet end of the smoke inlet pipe 3 is a smoke inlet section 31 connecting to the smoke collection hood 4, and near the outlet end of the smoke inlet pipe 3 is a smoke outlet section connecting to the fan box 1. When the fan is started, the cooking fumes pass sequentially through the smoke collection hood 4, the smoke inlet pipe 3, and the fan box 1, and are then discharged to a designated location. The oil separated from the fumes flows downwards along the direction of gravity; specifically, it flows downwards along the entire structure of the fan box 1, the smoke inlet pipe 3, and the smoke collection hood 4, eventually flowing into a target location for collecting the oil (e.g., an oil cup).

[0062] In this embodiment, to prevent oil from seeping outward through the connection between the smoke inlet pipe 3 and the smoke collection hood 4 during the backflow process, the inner surface of the smoke inlet 31 can be set inside the outlet of the smoke collection hood 4. In this way, when the oil flows downward under the action of gravity, when it flows to the smoke inlet 31 of the smoke inlet pipe 3, it can flow smoothly into the smoke collection hood 4 through the inner surface of the smoke inlet 31 under the action of gravity. Even if some oil accumulates at the connection between the smoke inlet pipe 3 and the smoke collection hood 4, it is difficult for it to flow out against the direction of gravity from the gap between the outer surface of the smoke inlet 31 and the smoke collection hood 4. This solves the problem of oil seepage at the connection between the smoke inlet pipe assembly and the smoke collection hood 4, thereby improving the user experience.

[0063] like Figure 10 As shown, in one embodiment, the smoke inlet pipe 3 may include an inner pipe 33 and an outer pipe 34 disposed around the inner pipe 33. Furthermore, an opening 330 is provided on the side wall of the inner pipe 33.

[0064] In this embodiment, the smoke inlet pipe 3 may include an inner pipe 33 and an outer pipe 34. A certain gap may be formed between the inner pipe 33 and the outer pipe 34, forming an annular cavity. This arrangement, compared to a single-layer pipe, allows the smoke inlet pipe 3 to have better noise reduction performance.

[0065] The inner tube 33 may have an opening 330 on its side wall. When the inner tube 33 has an opening 330, sound-absorbing cotton 35 may be placed in the annular cavity between the inner tube 33 and the outer tube 34. When the noise generated after the fan starts propagates into the smoke inlet pipe 3, it can be reduced by the sound-absorbing cotton 35 through the opening 330, so as to reduce the noise of the fan in the upstream section of the air inlet when it is working, and improve the noise reduction performance of the range hood.

[0066] like Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, the smoke inlet 31 may include the lower part of the smoke inlet pipe and the connector 2. The upper part of the connector 2 is connected to the lower part of the smoke inlet pipe 3, and the lower part of the connector 2 is connected to the smoke collection hood 4 of the range hood.

[0067] In this embodiment, the smoke inlet 31 may include a lower part of the smoke inlet pipe and a connector 2. Specifically, the lower part of the smoke inlet pipe may be a partial pipe section near the inlet end of the smoke inlet pipe 3, and the connector 2 is used to connect the smoke inlet pipe 3 to the smoke collection hood 4.

[0068] Specifically, the shape and structure of the connector 2 can be completely matched with the shape and structure of the smoke inlet pipe 3. For example... Figure 5As shown, when the cross-section of the smoke inlet pipe 3 is rectangular, the connector 2 can be a hollow frame structure with opposing upper and lower ends. The upper part (near the upper end) of the connector 2 can be connected to the lower part (near the lower end) of the smoke inlet pipe 3, or the upper end of the connector 2 can be integrally formed with the lower end of the smoke inlet pipe 3. The lower part of the connector 2 can be connected to the smoke collection hood 4, or the lower end of the connector 2 can also be integrally formed with the smoke collection hood 4.

[0069] like Figure 4 As shown, at least the inner surface of the smoke inlet pipe 3 is located inside the connector 2.

[0070] In this embodiment, the fit between the smoke inlet pipe 3 and the connector 2 also prevents oil from seeping out from the joint. Specifically, at least the inner surface of the smoke inlet pipe 3 is located inside the connector 2. Thus, when the oil flows downward under gravity, it can smoothly flow into the inner side of the connector 2 through the inner surface of the smoke inlet portion 31 of the smoke inlet pipe 3 under gravity, and then enter the smoke collection hood 4 through the connector 2. Even if some oil accumulates at the connection between the smoke inlet pipe 3 and the smoke collection hood 4, it is difficult for it to flow out against the direction of gravity from the gap between the outer surface of the smoke inlet pipe 3 and the smoke collection hood 4.

[0071] like Figure 4 As shown, in one specific embodiment, the upper part of the connector 2 has a first groove 21, and the lower part of the smoke inlet pipe is inserted into the first groove 21.

[0072] In this embodiment, the upper part of the connector 2 may be provided with a first groove 21, the open end of which faces upward. The first groove 21 is used to form a circumferential insertion part that mates with the smoke inlet pipe 3. The lower part of the smoke inlet pipe 3 can be inserted into the first groove 21. Thus, when the oil flows to the lower part of the smoke inlet pipe 3, it will enter the gap between the inner side of the lower part of the smoke inlet pipe and the first groove 21, and then enter the smoke collection hood 4 through the connector 2. In addition, a sealing element may be provided at the bottom of the first groove 21. When the lower part of the smoke inlet pipe 3 is inserted into the first groove 21, it can simultaneously abut against the sealing element, thereby further preventing the oil from flowing towards the gap between the outer side of the lower part of the smoke inlet pipe and the first groove 21.

[0073] Furthermore, the first groove 21 may include a groove bottom 210 and an outer side 211 and an inner side 212 surrounding both sides of the groove bottom 210, wherein the height of the outer side 211 is higher than the height of the inner side 212.

[0074] In this embodiment, the first groove 21 may include a groove bottom 210 and an outer side 211 and an inner side 212 surrounding the two sides of the groove bottom 210. The height of the outer side 211 is higher than the height of the inner side 212. If oil accumulates inside the first groove 21, when the accumulated height reaches the height of the inner side 212, the oil can flow inward through the inner side 212 into the smoke hood 4, without reaching the height of the outer side 211. This can more reliably ensure that the oil will not seep out from the mating position between the first groove 21 and the connector 2.

[0075] like Figure 11 and Figure 12 As shown, in one embodiment, the upper part of the connector 2 is connected to the lower part of the smoke inlet pipe 3 by a fastener. The lower part of the smoke inlet pipe 3 is provided with an installation hole, and the connector 2 is provided with a fastening hole 22. The fastening hole 22 is a blind hole, and the fastener passes through the installation hole and is connected in the fastening hole 22.

[0076] In this embodiment, the smoke inlet pipe 3 with the connecting member 2 can be fixedly connected to the smoke inlet pipe 3 by a fastener. Specifically, the fastener can be in the form of a screw. Of course, the fastener can also be in other forms. In this embodiment, the screw is mainly used as an example for illustration.

[0077] To install the fastener, the flue pipe 3 has a mounting hole near its lower end for the fastener to pass through. The connector 2 has a fastening hole 22 that matches the fastener; for example, when the fastener is a screw, the fastening hole 22 can be a threaded hole. During installation, the fastener can be installed from the inside out through the inside of the flue pipe 3, and the fastener can pass through the mounting hole and connect to the fastening hole 22. To prevent oil from leaking out at the mating point between the fastener and the fastening hole 22, the fastening hole 22 can be a blind hole.

[0078] It should be noted that, considering that the material of the smoke inlet pipe 3 is usually a standardized PVC pipe with a thin wall, it is impossible to set a blind hole. Therefore, in this embodiment, the blind hole is set on the connector 2. Furthermore, since the smoke inlet pipe 3 is set in the groove on the upper part of the connector 2, the fastening hole, which serves as a blind hole, needs to be opened from the inside to the outside on the connector 2.

[0079] Furthermore, at least one slot 23 opposite to the mounting hole is provided on the inner side 212, and the fastener is disposed in the mounting hole and the fastening hole 22 through the slot 23.

[0080] In this embodiment, when the fastening hole 22 and the mounting hole overlap with the inner side 212 to a certain extent in the height direction, since the fastener is installed from the inside to the outside through the inside of the smoke inlet pipe 3, a slot 23 can be provided on the inner side 212 of the first groove 21. The slot 23 can serve as a clearance groove for the fastener installation, so that the fastener can be placed in the mounting hole and the fastening hole 22 through the slot 23 without interfering with the inner side 212. Of course, if the fastening hole 22 and the mounting hole do not overlap with the inner side 212 in the height direction, the slot 23 may not be provided.

[0081] In one embodiment, the connector 2 and the smoke hood 4 cooperate to form an oil return channel 41, and the slot 23 is connected to the oil return channel 41.

[0082] In this embodiment, the connector 2 and the smoke hood 4, when engaged, form an oil return channel 41 that connects the smoke inlet pipe 3 and the smoke hood 4. This oil return channel 41 is connected to the slot 23. When oil flows to the inner side 212 of the first groove 21 of the connector 2 and the inner side of the smoke inlet pipe 3, since the slot 23 is the lowest point of the inner side 212, the oil will immediately flow to the slot 23 and then flow downwards into the smoke hood 4 through the oil return channel 41. The oil return channel 41 can be formed by the engagement of the upper ends of the connector 2 and the smoke hood 4. The specific form of the oil return channel 41 is not limited in this application.

[0083] In another embodiment, the upper part of the connector 2 is provided with a limiting step, and the lower part of the smoke inlet pipe abuts against the limiting step.

[0084] In this embodiment, the main difference from the form of setting the first groove 21 described above is that a limiting step is provided on the upper part of the connector 2. The lower part of the smoke inlet pipe can abut against the limiting step. Furthermore, the connection relationship between the connector 2 and the lower part of the smoke inlet pipe can be referred to the specific description of the above embodiment, and will not be repeated here.

[0085] In another embodiment, the lower part of the smoke inlet pipe has a second groove, the upper part of the connector 2 is inserted into the second groove, the second groove has an inner sidewall and an outer sidewall, and the inner sidewall is located inside the connector 2.

[0086] In this embodiment, the main difference from the embodiment described above, where the upper part of the connector 2 has a first groove 21 and the lower part of the smoke inlet pipe is inserted into the first groove 21, lies in the change in the relative positions of the grooves. Specifically, a second groove is provided at the lower part of the smoke inlet pipe, and the upper part of the connector 2 is inserted into the second groove. To ensure that the oil flows smoothly along the lower part of the smoke inlet pipe through the connector 2 into the smoke collection hood 4 without leaking out at the mating point between the smoke inlet pipe 3 and the connector 2, the inner wall of the second groove is located inside the connector 2.

[0087] In one embodiment, at least a portion of the inner surface of the lower end of the connector 2 is located inside the outlet of the smoke hood 4.

[0088] In this embodiment, the inner surface of the lower end of the connector 2 is located inside the outlet of the smoke hood 4. With this configuration, when the oil flows downward under the action of gravity, it can smoothly flow into the smoke hood 4 through the inner surface of the lower end of the connector 2 under the action of gravity. Even if some oil accumulates at the connection between the connector 2 and the smoke hood 4, it is difficult for it to flow out against the direction of gravity from the gap between the outer surface of the connector 2 and the smoke hood 4. There are no places where oil can easily seep in the entire return oil flow path, thereby improving the user experience.

[0089] like Figure 12 As shown, in one specific embodiment, the smoke hood 4 has a third groove 42, and at least a portion of the lower inner surface of the connector 2 is located within the third groove 42.

[0090] In this embodiment, a third groove 42 may be provided at the outlet of the smoke hood 4. The third groove 42 is positioned with its opening facing upwards and is adapted to fit the lower part of the connector 2. The lower part of the connector 2 can be inserted into the third groove 42. The third groove 42 has a bottom wall and opposing inner and outer side walls surrounding the bottom wall. An oil drain port 420 is provided on the inner side wall near the bottom wall.

[0091] When oil flows downward through the gap between the lower part of the connector 2 and the inner wall of the groove, it may flow into the third groove 42. In order to drain the oil in the third groove 42 in a timely manner and prevent it from accumulating in the third groove 42, an oil drain 420 can be provided on the inner wall of the third groove 42 near the bottom wall. The oil drain 420 can specifically be a plurality of rectangular openings spaced apart on the inner wall. Of course, the specific structure and number of the oil drain 420 are not specifically limited in this application.

[0092] like Figure 5 and Figure 6As shown, in one embodiment, the connector 2 has opposing front and rear portions, the rear portion of the connector 2 is quick-fitted with the smoke hood 4, and the front and / or side portions of the connector 2 are connected to the smoke hood 4 by fasteners.

[0093] During installation, the connector 2 can be pre-fixed to the lower end of the smoke inlet pipe 3. However, range hoods are usually installed against a wall. When it is necessary to install the smoke inlet pipe assembly onto the smoke collection hood 4, the installation may be inconvenient due to wall interference when operating near the rear side of the wall.

[0094] In this embodiment, the connector 2 may have opposing front and rear portions, as well as opposing left and right sides. The rear portion of the connector 2 can be connected to the smoke hood 4 via a quick-connect mechanism. Specifically, the rear portion of the connector 2 can engage with the smoke hood 4 via a snap-fit ​​mechanism.

[0095] When the rear part of the connector 2 is engaged with the smoke hood 4, the connector 2 has a hollow frame structure and has a front sidewall 24 and a rear sidewall 25. The rear sidewall 25 is provided with a snap-fit ​​part 251, which is used to cooperate with the snap-fit ​​groove on the smoke hood 4 to form a snap-fit ​​mechanism. Alternatively, the rear sidewall 25 of the connector 2 is provided with a snap-fit ​​groove, which is used to cooperate with the snap-fit ​​part 251 on the smoke hood 4 to form a snap-fit ​​mechanism.

[0096] Of course, the way the rear part of the connector 2 is connected to the smoke hood 4 via a quick-connect method is not limited to the example above. Those skilled in the art may make other modifications based on the technical essence of this application, but as long as the function and effect achieved are the same as or similar to this application, they should be covered within the scope of protection of this application. For example, taking the rear sidewall 25 of the connector 2 as an example, the snap-fit ​​part 251 can include multiple snap-fit ​​parts 251, and the multiple snap-fit ​​parts 251 can be spaced apart along the long side of the connector 2. The specific structure of the snap-fit ​​part 251 can be a protrusion with a guide slope at the end, or the structure of the snap-fit ​​part 251 can also be other forms.

[0097] like Figure 5 and Figure 6 As shown, in one embodiment, the connector 2 has a hollow frame structure, and the connector 2 has a front sidewall 24 and a rear sidewall 25. A connecting plate 241 is provided on the front sidewall 24, and a mating hole 2411 for installing the fastener is provided on the connecting plate 241.

[0098] In this embodiment, a connecting plate 241 may be provided on the front sidewall 24 of the connector 2. The connecting plate 241 may be a plurality of lug-shaped plates spaced apart along the long side of the connector 2. The connecting plate 241 is provided with mating holes 2411 for installing fasteners. Correspondingly, a fastening hole 22 for fixing the fastener is provided on the smoke hood 4. For example, when the fastener is a screw, the fastening hole 22 may be a screw hole.

[0099] When installing the smoke inlet pipe assembly with the smoke collection hood 4, first snap the rear part of the connector 2 into the smoke collection hood 4. At this time, the mating hole 2411 of the connecting plate 241 of the connector 2 is basically aligned with the fastening hole 22 on the smoke collection hood 4. Then, the fastener can be connected to the fastening hole 22 through the mating hole 2411, thereby fixing the smoke inlet pipe assembly to the smoke collection hood 4.

[0100] like Figure 13 As shown in the figure, this application also provides a range hood, which includes the above-mentioned smoke inlet pipe assembly. By setting the smoke inlet pipe assembly, the range hood can achieve the technical effect achieved by the smoke inlet pipe assembly implementation.
