Description

Technical Field

[0001] The invention relates to an indoor fresh air fan and a wind power generation system, in particular to a combined indoor fresh air fan and a wind power generation system, belonging to the field of wind power generation equipment. Background Art

[0002] With the progress of the times and the development of the economy, people's awareness of the effective use of natural wind resources and their own health has been continuously enhanced. Wind power generation and indoor air purification have attracted more and more attention, so various wind turbines, indoor fresh air fans, etc. have continued to appear. Traditional wind turbines are composed of wind blades, generators, poles, etc. This power generation system has the following disadvantages: First, it cannot be widely used in various occasions due to geographical restrictions, especially on roofs, wasting the wind resources on the roof; Second, it cannot fully and effectively utilize wind resources due to wind direction restrictions. Therefore, someone applied for Chinese utility model patent 201520068906.7, and the patent name is "A household wind turbine", which includes a support rod, a group of air guide boxes, a group of blades, a rotating shaft, a transmission, a generator and a battery. The support rods are respectively provided with a group of air inlets and a group of air outlets. A group of air guide boxes are respectively provided with a group of air guides around them, and an air outlet is provided at the bottom. A group of air guide boxes are respectively installed at a group of air inlets of the support rod, and the air outlet of a group of air guide boxes is communicated with the air inlet of the support rod. The two ends of the rotating shaft are respectively movably installed in the support rod through bearing seats. Although the structure is simple and suitable for household use, the air guide box only has air inlets in four directions, which cannot fully and effectively allow natural wind from different angles to blow into the tube, resulting in low power generation efficiency. Someone else has applied for Chinese invention patent 201611082467.0, the name of the patent is "A wind gathering tower and a wind gathering type wind turbine generator set", which includes a wind gathering device, an air guide pipe, an air supply pipe, and a diffuser that are sealed and fixedly connected in sequence. The wind gathering device is arranged at the top of the wind gathering tower for collecting wind energy. An air outlet is arranged below the wind gathering device. The air inlet end of the air guide pipe is connected to the air outlet of the wind gathering device, the air outlet of the air guide pipe is connected to the air inlet of the air supply pipe, the air outlet of the air supply pipe is connected to the air inlet of the diffuser, and the air outlet of the diffuser is connected to the air outlet. The wind gathering tower can collect air and form a vortex flow under the action of wind pressure, which is accelerated and pushed into the working pipe. The impeller is placed in the working pipe to drive the generator to convert wind energy into electrical energy.The disadvantages of this structure are: 1. The air inlet of the wind collecting device is in two directions (i.e., horizontal and vertical directions). The wind collecting device cannot fully and effectively allow natural wind from different angles to blow into the tube, and cannot fully utilize natural wind resources, thereby weakening the wind power generation effect; 2. The invention states in claim 9: A wind shield is provided at the exhaust port, and the wind shield is directly opposite to the outlet of the diffuser to prevent natural wind from blowing into the diffuser from the exhaust port; It is well known that in a small area, the wind speed, wind volume and wind pressure in the atmosphere are the same. The air inlet and outlet of the wind collecting device of the invention are both horizontal, that is, natural wind can be blown into the pipe from the wind collecting device and the outlet at the same speed and pressure at the same time, so that the airflow in the pipe is in a state of opposite flow but cannot circulate, and the blades on the generator will not rotate, and the power generation effect cannot be achieved; the wind shield set at the outlet has no effect. Even if the wind speed entering from the wind collecting device is greater than the wind speed entering from the outlet, the speed difference of the natural wind flowing in opposite directions greatly reduces the wind speed in the pipe and affects the power generation effect. In addition, the traditional indoor fresh air fan uses electricity transmitted by the national power grid. If it is turned on for a long time, the power consumption is large and the cost is increased; if it is not turned on for a long time, the indoor air quality cannot be guaranteed. Moreover, the fan, purification assembly and heat exchanger in the traditional fresh air fan are installed in the same casing, which not only makes the machine bulky and occupies limited space in the home, but also increases indoor noise, affecting people's lives and health.

An indoor air outlet and an indoor air inlet are provided on the other side of the inner casing, and the indoor air outlet corresponds to the high-efficiency filter assembly of the heat exchanger.

[0005] The present invention discloses a combined indoor fresh air fan and wind power generation system. When working, natural wind from different angles blows into the top air inlet, the upper air inlet wide-mouth member and the lower air inlet wide-mouth member of the multi-directional air inlet assembly and converges downward into the cavity of the large air collection channel, then enters the small air collection channel downward along the large air collection channel, and then enters the generator set through the ventilation pipe and the venturi tube. The converged wind blows the fan blades of the generator in the generator set, and the rotation of the fan blades causes the generator to generate electric energy, and passes through the second, third to Nth generators (the power of the air supply motor, the exhaust fan and the exhaust fan in the outdoor unit of the indoor fresh air fan can be selected according to the amount of fresh air required in each floor, and the total power consumption of the motors on each floor is calculated to calculate the total power consumption of the whole house, and one or N generators are installed), so that the generator set generates electric energy, and the converged natural wind continues to be transported to the exhaust main pipe, and is transported from the exhaust main pipe to the exhaust branch pipe (a corresponding number of exhaust branch pipes can be branched out according to the number of rooms on the same floor). ), and then the exhaust branch pipe transmits the natural wind to the outdoor unit of each floor through the outdoor air inlet pipe. At the same time, the electric energy generated by the generator set is also transmitted to the outdoor unit and indoor unit of each floor through the power line. The blower in the outdoor unit starts to work, and the natural wind enters the outdoor unit through the exhaust branch pipe and the outdoor air inlet pipe. The natural wind is transmitted to the indoor unit through the indoor air inlet pipe by the blower. The natural wind passes through the primary filter assembly for primary filtration, and then enters the heat exchanger to exchange heat with the indoor air output to make the air temperature more balanced and suitable. Finally, after high-efficiency filtration by the high-efficiency filter assembly, the fresh air is transmitted to the room through the indoor air outlet. When the blower is working, the exhaust fan also starts to work. The exhaust fan transmits the dirty air in the room to the indoor unit through the indoor air inlet, and exchanges and balances the heat with the outdoor fresh air through the heat exchanger, and then transmits it to the outdoor unit through the indoor air outlet pipe. The exhaust fan in the outdoor unit discharges the dirty air from the outdoor air outlet pipe to the outside.The combined indoor fresh air fan and wind power generation system of this scheme combines the wind power generation mechanism and the indoor fresh air exchange mechanism together. The wind power generation mechanism consists of a multi-directional air inlet assembly, a wind collecting assembly, a generator set and an exhaust duct assembly. The multi-directional air inlet assembly can be set at the top of the floor and is less restricted by the region. In the multi-directional air inlet assembly, a lower air inlet wide-mouth piece is set around and on the upper end of the large fixed seat. A small fixed seat is set at the center of the upper end of the large fixed seat. The small fixed seat faces vertically upward. An upper air inlet wide-mouth piece is set around the small fixed seat. The lower air inlet wide-mouth piece and the upper air inlet wide-mouth piece face in all directions above the horizontal plane, so as to collect natural wind from different angles. Moreover, the small fixed seat and the lower air inlet wide-mouth piece and the upper air inlet wide-mouth piece have large inlet inner diameters, so that natural wind is easier to blow in. The inner diameter from the inlet to the outlet gradually decreases, so that the air flow speed can be accelerated. All the collected natural wind enters the cavity between the large air collecting channels together, and then enters the generator set through the small air collecting channels, the ventilation duct and the venturi tube. The wind channel, small wind collecting channel and venturi tube all have large inlet and small outlet. The wind speed of the input natural wind gradually increases after passing through the large wind collecting channel, small wind collecting channel and venturi tube, and is finally delivered to the generator set, which can effectively improve the power generation efficiency of the generator set. The electric energy generated by the generator set is provided to the supply fan and exhaust fan of the outdoor unit for operation. The natural wind passing through the generator set is delivered to the room through the exhaust main pipe, exhaust branch pipe, outdoor air inlet pipe, outdoor unit, supply fan, indoor air inlet pipe, indoor unit, primary filter assembly, heat exchanger, high-efficiency filter assembly and indoor air outlet, which accelerates the air flow speed in the exhaust branch pipe and exhaust main pipe and improves the power generation efficiency, thereby effectively utilizing the natural wind resources, providing electric energy to the fresh air exchange mechanism, saving the energy consumption of the fresh air exchange mechanism, and bringing good and fresh air to the room. In the fresh air exchange mechanism, the supply fan, exhaust fan and other components are arranged in the outdoor unit, which reduces the indoor noise and is more beneficial to people's physical and mental health.

[0006] The combined indoor fresh air fan and wind power generation system of the present invention has a lightning rod arranged on the fixed frame, and the lightning rod is connected to the grounding wire. With the lightning rod and the grounding wire, lightning can be prevented from striking the fan power generation mechanism. A cleaning port is formed below the small air collection channel, and a cleaning port cover is arranged in the cleaning port. Natural wind is easy to bring in dust, leaves and other impurities after blowing in. Since the small air collection channel is a pipe bend close to 90 degrees, impurities are easily deposited at this position. The cleaning port and the cleaning port cover are arranged at this position, and the deposited impurities can be cleaned regularly to ensure the circulation of the channel. A water trough is formed in one of the lower fixed shells of the generator set, and a drainage hole is opened in the water trough, and a water outlet pipe is arranged under the drainage hole. The rainwater entering can be discharged outward through the drainage hole in the water trough through the water outlet pipe. The large fixed seat is a trapezoidal polyhedron or a hemisphere. A dehumidifier, a semiconductor cooling and heating device and an ultraviolet sterilizer are arranged in the air supply guide chamber of the outdoor unit. The dehumidifier can dehumidify the humid air, the semiconductor cooling and heating device can cool or heat the input air to a suitable temperature, and the ultraviolet sterilizer can kill harmful bacteria in the air, thereby ensuring that healthy, fresh, and temperature-appropriate air can be input to ensure the health of the human body. The multi-directional air inlet assembly has a square, rhombus, or sphere shape. The small fixing seat, the lower air inlet wide-mouth piece, and the upper air inlet wide-mouth piece have a cone or rhombus shape and can be assembled in an integral or assembled manner. The large air collecting duct and the small air collecting duct have a cone or rhombus shape and can be assembled in an integral or assembled manner. The multi-directional air inlet assembly, the small fixing seat, the lower air inlet wide-mouth piece, the upper air inlet wide-mouth piece, the large air collecting duct, and the small air collecting duct can be designed into different shapes such as cones, rhombuses, or other geometric shapes as needed.
