detailed description

Below, referring to the accompanying drawings, through the description of the embodiments, the specific implementation of the present utility model, such as the shape and structure of each component involved, the mutual position and connection relationship between each part, the function and working principle of each part, and manufacturing The process, operation and use methods, etc. are further described in detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solutions of the present utility model.

As shown in the figure, it is an energy-saving range hood, which includes a centralized channel 1, an air collection port 2 arranged on the concentrated channel 1, an exhaust fan 8 arranged inside the concentrated channel 1, and a fan connected to the exhaust fan 8 6.

The gas collection port 2 includes a gas collection end and a gas outlet end, wherein the diameter of the gas collection end is much larger than the diameter of the gas outlet end, and the opening of the gas collection end points to the ground. For the convenience of inhalation, the gas collecting end is arranged above the gas stove, and for the convenience of exhausting, the gas outlet is arranged inside the centralized channel 1 . In order to prevent the gas inside the centralized channel 1 from entering the gas collection port 2 through the gas outlet and then into the room, the opening of the gas outlet points to the sky.

The centralized passage 1 is located inside the building, and the air collection ports 2 of each household on different floors can lead to the centralized passage 1. According to the principle of air heating and rising, the air inside the centralized passage 1 will be discharged upwards, thereby forming the concentrated passage 1. Relative to the negative pressure in the room, the oil fume will be sucked into the centralized channel 1 through the air collecting port 2, and the entry of the oil fume will bring a lot of heat, which further strengthens the oil extraction and exhaust function of the energy-saving range hood. The cross-section of the concentrated channel 1 is square, and its body is a rectangular hollow pipe. In order to increase the exhaust efficiency, the concentrated channel 1 is perpendicular to the horizontal plane, and the upper end of the concentrated channel 1 remains open, and the lower end of the concentrated channel 1 is provided with an inlet. The area of the air port and the air inlet is greater than the area of the upper opening of the concentration channel 1 .

In order to collect the oil in the centralized passage 1 and keep the centralized passage 1 clean and hygienic, the air inlet is arranged on the lower side wall of the centralized passage 1, and the bottom port of the concentrated passage 1 is provided with an arc-shaped closed door, and the circular arc shape of the closed door A collection port is provided at the lowest end of the arc, and an end cover is provided on the collection port to collect the oil accumulated in the closed door by opening and closing the end cover.

In order to prevent children and pets from entering the centralized channel 1 through the air inlet and being injured, the air inlet is provided with louvers, and the louvers are fixed to the centralized channel 1 by bolts. When necessary, the louvers can be opened and the centralized channel 1 for deep work.

In order to increase exhaust efficiency, an exhaust fan 8 is provided inside the centralized channel 1 . For providing power to the exhaust fan 8, because the wind at the top of the building floor is relatively large, there is no shelter and there are few people, the upper end of the centralized channel 1 is provided with a fan 6 connected to the exhaust fan 8. The fan 6 is provided with a driving link, which is also connected with the exhaust fan 8, and the fan 6 provides torque and rotating speed for the exhaust fan 8 through the drive link. In order to keep the fan 6 facing the wind direction all the time, the fan 6 is also provided with a rudder, which is perpendicular to the fan 6, and the rudder is blown by the wind so that the fan 6 is always facing the wind direction. Because wind energy is directly used to drive the fan 6 and then the exhaust fan 8, there are few intermediate energy conversion links, thereby greatly improving energy utilization efficiency and reducing waste.

In order to further prevent the gas inside the centralized channel 1 from entering the gas collection port 2 through the gas outlet and then into the room, the gas collection port 2 is provided with a valve 3, and the gas collection port 2 can be switched on and off by the user opening and closing the valve 3 .

In order to further strengthen the exhaust effect of the energy-saving range hood and prevent the exhaust effect of the energy-saving range hood from being greatly reduced due to the situation of no wind, the top of the centralized channel 1 is provided with a solar cell 7 and a motor 5, the motor 5 Drive exhaust fan 8 through connecting rod.

Due to the regularity of people's cooking time, people spend more time on energy-saving range hoods, that is, the energy required by energy-saving range hoods is unbalanced in time. To provide energy and enhance efficiency during peak hours, the centralized channel 1 is also provided with a battery for storing the power generated by the solar cell 7 . The battery, the solar cell 7 and the motor 5 are connected in pairs by wires.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned methods, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the utility model, or Directly applying the ideas and technical solutions of the utility model to other occasions without improvement is within the protection scope of the utility model. The protection scope of the present utility model should be determined by the protection scope defined in the claims.
