Since stir-frying produces a lot of oil smoke, a range hood is usually installed to collect and discharge the smoke produced by stir-frying. The range hood is an indispensable appliance in the kitchen. The most common and widely used is the upper exhaust type oil fume purification system. The range hood technology is mature and can significantly reduce kitchen smoke. At the same time, it can also treat the smoke and reduce the harmful substances in the smoke.
[0003] However, the range hoods currently used in kitchens are only equipped with an independent fan. When the range hood is turned on during use, all the smoke extraction ports will be opened, resulting in a large amount of energy waste. Moreover, when the power is constant, it is difficult to adjust the ventilation volume of the smoke collection equipment above each stove, resulting in poor applicability. Utility Model Content
[0004] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide an energy-saving intelligent kitchen smoke exhaust ventilation system.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0023] like Figures 1 to 6 The embodiment of the present invention presented preferably provides an energy-saving intelligent kitchen smoke exhaust ventilation system, including a range hood body 1, wherein the range hood body 1 has more than two exhaust zones 2, and the range hood body 1 has smoke supply pipes 3 that can be connected to the exhaust zones 2 respectively, and a switching structure 4 is provided between the exhaust zones 2 and the smoke supply pipes 3 to allow the two to be connected or closed.
[0024] Specifically, by setting up an on-off structure between the exhaust area and the smoke supply pipe, the on-off structure can control the connection or closing between any exhaust area and the smoke supply pipe respectively. When the kitchen stove produces a large amount of oil smoke during stir-frying, the user can close the remaining exhaust areas through the on-off structure and only keep the exhaust area directly above the stir-frying area connected. When the fan power is constant, the exhaust volume of the retained exhaust area is effectively enhanced, the problem of oil smoke escape is avoided, and energy consumption is effectively reduced, thereby achieving energy-saving effects.
[0025] Furthermore, the on-off structure 4 includes a smoke guide tube 41 having a circular outer shape, the cross-section of the smoke delivery tube 3 is circular, and the smoke guide tube 41 is coaxially rotatably arranged in the inner cavity of the smoke delivery tube 3. A smoke guide port 42 is provided on one side of the smoke guide tube 41 corresponding to the connection between the smoke delivery tube 3 and the exhaust area 2. The smoke guide port 42 can rotate with the smoke guide tube 41 so that it is connected or disconnected with the exhaust area 2.
[0026] Specifically, the smoke guide pipe is rotated so that the smoke guide port on the smoke guide pipe rotates accordingly. When the smoke guide port is rotated to the connection point between the smoke delivery pipe and the exhaust area, it is in a connected and open state. When the smoke guide port is rotated away from the connection point between the smoke delivery pipe and the exhaust area and is opposite to the inner wall of the smoke delivery pipe, it is in a closed and non-ventilated state.
[0027] Furthermore, a long through-hole 31 is provided on the upper side of the smoke delivery pipe 3, and a handle 32 is provided on one side of the smoke guide pipe 41 within the long through-hole 31. The handle 32 can be moved along the length of the long through-hole 31 to drive the smoke guide pipe 41 to rotate relative to the smoke delivery pipe 3. The user can then manually pull the handle to rotate the smoke guide pipe to connect or disconnect the smoke delivery pipe from the exhaust area.
[0028] Furthermore, magnets capable of magnetically attracting the handle 32 are provided at both ends of the long through-hole 31. When the handles are respectively located at both ends of the long through-hole, the corresponding smoke delivery pipe and the exhaust area are in a connected or closed state, and are kept fixed by magnetic attraction.
[0029] Furthermore, the cross-section of the smoke delivery tube 3 has a first endpoint, a second endpoint, and a third endpoint along the circumference. A line connecting the first and third endpoints forms a first reference line, which coincides with the center of the smoke delivery tube 3 and is parallel to a horizontal plane. A line connecting the second endpoint and the center of the smoke delivery tube 3 forms a second reference line, which is perpendicular to the first reference line. The lower end of the elongated through-hole 31 is located between the first and second endpoints, and the upper end of the elongated through-hole 31 is located between the second and third endpoints. This effectively prevents the smoke guide tube from loosening or deflecting relative to the smoke delivery tube due to gravity.
[0030] Furthermore, the range hood body 1 includes a connecting base 11 and a housing 12 rotatably mounted on the connecting base 11. The exhaust area 2 is formed within the housing 12. The connecting base 11 has a smoke exhaust pipe 13. The smoke supply pipe 3 includes a first connecting pipe 14 connected to the lower end of the smoke exhaust pipe 13 and a second connecting pipe 15 connected to the inner cavity of the housing 12. The on-off structure 4 is disposed in a one-to-one correspondence within the second connecting pipe 15. A screw hole 16 is disposed on one side of the first connecting pipe 14, and a through-hole 17 is disposed on one side of the second connecting pipe 15. A connecting screw threadedly connected to the screw hole 16 is disposed within the through-hole 17. When the connecting screw is locked in the screw hole 16, the first connecting pipe 14 and the second connecting pipe 15 are fixedly connected in alignment. Furthermore, an oil fume separator 18 is disposed within the first connecting pipe 14.
[0031] Specifically, when the user needs to clean, the casing can be loosened from the connecting seat by removing the connecting screws, and the casing can then rotate relative to the connecting seat. At this time, the first connecting tube and the second connecting tube that constitute the smoke delivery pipe can be deflected and offset, so that the oil fume separator in the first connecting tube and the on-off structure in the second connecting tube are exposed, thereby facilitating disassembly, cleaning, and maintenance by the user, and avoiding the trouble of overall disassembly.
[0032] Furthermore, an exhaust fan 19 is provided in the smoke exhaust pipe 13 .
[0033] Furthermore, a limiting rod 20 is provided on one side of the housing 12, and the limiting rod 20 can abut against the side wall of the first connecting tube 14 as the housing 12 rotates relative to the connecting seat 11, thereby limiting the rotation stroke of the housing relative to the connecting seat.
[0034] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
