When internal exhaust is needed, the first sealing plate 200 can be connected to the external exhaust port 140 to block the external exhaust port 140. At this time, the second sealing plate 300 is not inserted into the internal exhaust chamber 120, so that the smoke sucked by the turbine fan 111 enters the internal exhaust chamber 120 for filtration and then is discharged from the internal exhaust port 150. When external exhaust is needed, the first sealing plate 200 can be omitted and the second sealing plate 300 can be inserted into the internal exhaust chamber 120 to separate the internal exhaust port 150 from the turbine chamber 110. At this time, the smoke is discharged from the external exhaust port 140. Through the above structure, internal and external exhaust switching can be achieved, the structure is simple and the cost is low.

[0033] Specifically, the volute assembly is arranged inside the range hood, and a rotatable turbine fan 111 is arranged in the turbine chamber 110 arranged in the main body, and the rotation of the turbine fan 111 can realize suction, and the output end of the turbine chamber 110 can be connected to the inner row chamber 120, and a filter body can be arranged in the inner row chamber 120, and the filter body can be a filter mesh, activated carbon and other filter materials, and the air inlet 130 arranged in the turbine chamber 110 is the air inlet, and the air inlet 130 can be connected to the corresponding smoking port 400 of the range hood, and the external air outlet 140 can be connected to the external exhaust pipe of the range hood, and the internal air outlet 150 can be arranged on the range hood to exhaust air into the room. In actual use, the first sealing plate 200 and the second sealing plate 300 can be selectively installed on the main body. When external exhaust is required, the second sealing plate 300 can be installed in the inner row chamber 1 20, it can be understood that the inner exhaust port 150 is arranged at the rear of the filter body, and the second sealing plate 300 can be installed in front of the filter body to prevent the smoke from polluting the filter body during external exhaust, and the filter body does not need to be disassembled and assembled, and the operation is simple.

When internal exhaust is required, the first sealing plate 200 is connected to the outer exhaust port 140, and fasteners can be used for connection. The specific connection structure is not specifically limited. The second sealing plate 300 does not need to be installed with the main body, so that the smoke can pass through the inner exhaust cavity 120 and be discharged from the inner exhaust port 150 after being filtered by the filter body. Through the above structure, the mode switching between internal and external exhaust can be realized, and the structure is simple and the manufacturing cost is low.

It can be understood that the plug-in port 160 can be arranged close to the turbine chamber 110 so that the filter body in the inner row chamber 120 can be separated by the second sealing plate 300. It can be understood that when inner row is required, the plug-in port 160 can be provided with a seal to prevent smoke from escaping from the plug-in port 160.

The above structure can improve the suction capacity.

[0039] Specifically, it can be understood that the first turbine shell 171 and the second turbine shell 172 are both provided with a turbine fan 111. The first turbine shell 171 and the second turbine shell 172 are arranged on the left and right, and the turbine fans 111 rotate in opposite directions so that the air outlet ends can be closed together.

[0042] Reference Figure 1 to Figure 2In some embodiments of the present invention, the external air outlet 140 is circular, and is disposed at the top of the first turbine shell 171 and the top of the second turbine shell 172. Specifically, the external air outlet 140 can be connected to the external air outlet pipe, and the first turbine shell 171 and the second turbine shell 172 are disposed close to each other, so that the external air outlet 140 can be connected to the output parts of the two turbine shells at the same time, which can improve the external exhaust effect, and the external air outlet 140 is disposed at the top so that it is convenient to connect to the external air outlet pipe.

[0043] In some embodiments of the present invention, the turbine housing 170 and the inner exhaust housing 180 are both metal parts.
