Since the embodiments disclosed in the present application can be arranged in different directions, these directional terms are only used as illustrations and should not be regarded as limitations. For example, "upper", "lower" are not necessarily limited to the direction opposite or consistent with the direction of gravity. In addition, the features defined as "first", "second" can explicitly or implicitly include one or more of the features.

[0021] Referring to Figs. 1-4 A range hood includes a smoke collecting hood 1 and a fan system 2 arranged above the smoke collecting hood 1. A first air inlet 11 is formed in the middle of the side of the smoke collecting hood 1 facing the smoke source. The fan system 2 is located above the ceiling 100 of the kitchen, and the fan system 2 includes a fan system input end 21, and the fan system 2 is arranged transversely, i.e. the fan system input end 21 is arranged downward.

[0022] Referring to Figs. 2-4The range hood also includes a connecting pipe assembly connecting the smoke collection hood 1 and the fan system 2. The connecting pipe assembly is located inside the cabinet 200. The connecting pipe assembly includes a first connecting pipe 31, a second connecting pipe 32, a third connecting pipe 33, and a fourth connecting pipe 34. The first connecting pipe 31 and the second connecting pipe 32 are spaced apart along the left-right direction of the smoke collection hood 1. Both the first connecting pipe 31 and the second connecting pipe 32 are vertically arranged square columns. A first air outlet 14 and a second air outlet 15 are respectively opened on the left and right sides of the top of the smoke collection hood 1. One end of the first connecting pipe 31 is in fluid communication with the first air outlet 14, and one end of the second connecting pipe 32 is in fluid communication with the second air outlet 15. The third connecting pipe 33 extends along the left-right direction of the smoke collection hood 1, and the ends of the first connecting pipe 31 and the second connecting pipe 32 away from the smoke collection hood 1 are in fluid communication with the left and right ends of the third connecting pipe 33, respectively. One end of the fourth connecting pipe 34 is in fluid communication with the top of the third connecting pipe 33, and the other end of the fourth connecting pipe 34 is in fluid communication with the fan system 2 (fan system input end 21). In this embodiment, the fourth connecting pipe 34 includes a smoke pipe 341 and an air outlet hood 342, which are arranged sequentially from top to bottom. The smoke pipe 341 is connected to the fan system 2, and the air outlet hood 342 is connected to the third connecting pipe 33.

[0023] The fan system 2 is installed above the suspended ceiling 100mm, which reduces noise and avoids encroaching on the cabinet space. The third connecting pipe 33, the first connecting pipe 31, the second connecting pipe 32, and the fume hood 1 are arranged in a "U" shape. The central cabinet space is completely preserved, avoiding the central space of the cabinet and maximizing the space utilization of the cabinet for user convenience. At the same time, the first connecting pipe 31 and the second connecting pipe 32 can also serve as the left and right side panels of the cabinet, and the cabinet doors can be directly installed on them, eliminating the need for left and right side panels, further saving space and cabinet costs.

[0024] The fume hood 1 has a second air inlet 12 and a third air inlet 13 on the left and right sides facing the smoke source, respectively. The second air inlet 12 is set to the first connecting pipe 31, and the third air inlet 13 is set to the second connecting pipe 32, so as to realize the negative pressure zone to diffuse to both sides, and then cooperate with the first air inlet 11 in the middle to further improve the fume extraction effect.

[0025] The air inlets of the fume hood 1 are in fluid communication with at least one of the first air outlet 14 and the second air outlet 15, respectively, and preferably, each air inlet is in fluid communication with each air outlet, as in the present embodiment, by making the fume hood 1 hollow, or alternatively, a connecting pipe can be additionally provided. In addition, preferably, the first air outlet 14 and the second air inlet 12 are in position correspondence, and the second air outlet 15 and the third air inlet 13 are in position correspondence, where the position correspondence can mean that each air outlet is located directly above or substantially directly above the corresponding air inlet, so as to shorten the path of the fume and promote the upward discharge of the fume.

[0026] The "fluid communication" in the present utility model refers to the spatial positional relationship between two components or parts (hereinafter collectively referred to as the first part and the second part), i.e. the fluid (gas, liquid or mixture of the two) can flow or / and be transported from the first part to the second part along the flow path, which can be directly connected between the first part and the second part, or indirectly connected between the first part and the second part through at least one third party, which can be a fluid passage such as a pipe, a channel, a conduit, a flow guide, a hole, a groove, etc., or a chamber allowing fluid to flow, or a combination thereof.
