As shown in fig. 1 and 2, the two interfaces 111 are a first interface 1111 and a second interface 1112, respectively, and the first interface 1111 and the second interface 1112 are arranged at one end of the bottom plate of the case 11 in the front-rear direction. According to the specific condition of the installation space, the fan 12 can be selectively installed on the left side or the right side of the connecting pipe 3, so that the rear side surface of the box 11 is close to the installation wall as much as possible, and the interface 111 close to one side of the installation wall is connected with the connecting pipe 3. When the fan 12 is installed on the left side of the connection pipe 3, the first port 1111 is close to the rear installation wall, so that the first port 1111 is connected with the connection pipe 3; referring to fig. 6, when the fan 12 is installed at the right side of the connection pipe 3, the second port 1112 is adjacent to the rear installation wall, so that the second port 1112 is connected with the connection pipe 3.
As shown in fig. 1 and 2, in order to enable the housing 11 and the connection pipe 3 to be attached to the installation wall, one of the ports 111 is provided at the front end of the base plate 101, and the other port 111 is provided at the rear end of the base plate 101. That is, one of the connectors 111 is attached to the front side plate 103 of the case 11, the other connector 111 is attached to the rear side plate 104 of the case 11, and the connector 111 is disposed near the front edge or the rear edge of the bottom plate 101, so that the back of the connecting pipe 3 is substantially flush with the back of the case 11 after the connecting pipe 3 is connected to the corresponding connector 111.
Further, as shown in fig. 2 and 4, the fan 12 is disposed on the bottom plate 101 of the box 11, the air inlet 122 of the fan 12 faces the top plate 102 of the box 11, and the air flow entering the box 11 through the interface 111 is guided by the top plate 102 of the box 11 and then enters the air inlet 122 of the fan 12, so that the air flow is smoother, and the air flow loss is smaller.
Optionally, in conjunction with fig. 4 and 5, the air inlet 122 of the fan 12 is disposed in a gap with the top plate 102 of the box 11, so as to form an air inlet space 112 on the upper side of the fan 12, thereby ensuring that the air flow entering the box 11 from the connection pipe 3 can more smoothly enter the fan 12.
As shown in fig. 2 to 4, the blower 12 and the air outlet cover 15 are installed at the left side of the connection pipe 3, and at this time, the first port 1111 at the rear side is connected to the connection pipe 3, and the second port 1112 is sealed by the baffle 13.
Referring to fig. 2, 6 and 7, the blower 12 is installed at the right side of the connection pipe 3, corresponding to the bellows structure 1 of the view angle shown in fig. 3, rotated 180 degrees clockwise, and at this time, the second port 1112 is located at the rear side, connected to the connection pipe 3, and the first port 1111 is sealed by the barrier 13.
Here, since one port 111 needs to be connected to the connection pipe 3, a baffle 13 may be provided to seal the port 111 that is idle.
As shown in fig. 6, in order to facilitate the assembly and disassembly of the baffle 13, the baffle 13 is connected with the box 11 through a plurality of fasteners 14, and the fasteners 14 can be bolts or screws. When the range hood has a moving requirement and the arrangement mode of the fan 12 needs to be adjusted according to a new installation environment, the baffle 13 on the required interface 111 can be detached, and the detached baffle 13 can cover the previously opened interface 111 with reference to fig. 2. Of course, two baffles 13 may be provided, with one baffle 13 serving as a backup. During the transfer, the spare flap 13 is mounted at the previously open interface 111. The baffle 13 detached from the interface 111 to be connected after the machine is moved may have serious oil contamination, aging of sealing elements and the like, and is discarded.
As shown in fig. 8, in order to improve the sealing property of the connection between the baffle 13 and the casing 11, a sealing member 16 is interposed between the baffle 13 and the casing 11, and the sealing member 16 may be a seal ring.
