Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a view showing a ventilation system according to an embodiment of the present invention, and FIG. 2 is a view schematically showing the ventilation system of FIG. 1 installed in a factory.

1 and 2, the ventilation system 90 according to an embodiment of the present invention includes an exhaust pipe 100 and a ventilation device 110.

The exhaust pipe 100 is a poly series and includes a straight PVC (Poly Vinyl Chloride) pipe 101 and an elbow pipe 103 connecting the plurality of PVC pipes 101 to each other.

One side of the exhaust pipe 100 may be coupled to the engaging portion 97 of the manhole cover, which is formed with a fastening portion (101a) is installed in the sewer collection. For example, the fastening portion 100a may have various shapes for fastening to the coupling portion 97, but may be simply formed with threads to be coupled to each other in the form of bolts and nuts.

Of course, the exhaust pipe 100 according to the embodiment of the present invention does not necessarily need to use the PVC pipe (101). In other words, a flexible duct may be used, and the exhaust pipe 100 may be flexibly and flexibly selected according to a place or purpose to be installed and installation costs, and the like.

Ventilation apparatus 110 according to an embodiment of the present invention is installed on the other side of the exhaust pipe (100). The ventilator 110 of FIG. 1 is driven using sunlight, but may operate as a power source. For example, the ventilation device 110 may determine that the power source due to sunlight is insufficient, or may perform an exhaust operation by driving the fan with wind power in a condition in which wind is present.

That is, the ventilator 110 receives sunlight and charges the battery in an environment where sunlight is present to perform an exhaust operation. Of course, the exhaust operation may be performed while charging. On the other hand, when it is determined that the rainy season continues and the power charged from sunlight is insufficient, the ventilator 110 releases the connection (or operation) of the motor drive shaft connected to the fan to perform the exhaust operation with wind power. . Of course, if the surrounding environment is determined to be a wind condition, the drive shaft connected to the fan may be disconnected to operate the fan by the wind. To this end, the ventilation device 110 may operate in a preset manner by measuring whether there is wind or light using an optical sensor, an air volume sensor, or a wind speed sensor.

The ventilation device 110 is exposed to the outside as shown in Figure 1 is provided with a solar cell or a solar heat collecting plate for receiving or collecting sunlight. The ventilator 110 drives the motor with the collected solar energy to operate a fan connected to the motor to perform an exhaust operation. In the process of this, the ventilation device 110 releases the drive shaft connected to the fan so that the fan is driven by wind when the condition is to be driven by the wind. Here, "release" may also separate the drive shaft, but may mean that the power supplied to the motor is cut off so that the drive shaft rotates freely.

The method of controlling the ventilator 110 for the release of the drive shaft may be various, but for example, a method using a linear motor utilized in an automatic door opening/closing device, a method using a linear motor and a rotating motor in parallel, a driving motor A method of electrically converting the polarity of the magnetic material constituting the interior may be possible. Alternatively, a method using a suction motor such as a small DC suction motor may be used. In the linear motor, since the drive shaft performs a linear movement rather than a rotational movement, an operation of inserting and separating the drive shaft into the fan may be performed. The suction motor may be a model MB3650-SUC&SUC-390.

As described above, the ventilator 110 according to an embodiment of the present invention can simultaneously perform fan operation by solar power and fan operation by wind power by combining and releasing or separating a drive shaft of a fan and a motor in various ways. In addition, since various methods may be possible, embodiments of the present invention are not particularly limited to the above.

On the other hand, the ventilation device 110 according to an embodiment of the present invention may further include an air purifying portion in the connection portion connected to the exhaust pipe 100. It is possible to implement a more environmentally friendly device by removing the gas or odor pollutant exhausted to the outside through the air purifying unit and discharging it into the air. A filter unit such as a hepa filter can be simply formed, but various filters can be configured in addition to the pollution source. Alternatively, various devices for removing odors may be installed, and the air may be purified by spraying the odor removing agent in a spray form by measuring the degree of odor through a sensor. The driving unit (for example, the control unit) operates the sprayer according to the measurement of the degree of odor.

FIG. 3 is a view showing the ventilation device of FIG. 1, and FIG. 4 is a block diagram showing a driving unit of the ventilation device of FIG. 3.

3 and 4, the ventilator 110 according to an embodiment of the present invention includes a solar light receiving unit 300, a driving motor 310, a (exhaust) fan 320, and a driving unit 330. Includes some or all.

Here, "including some or all" may be configured by omitting some components, such as the driving unit 330, or by configuring some components, such as the driving unit 330, by being integrated into the solar light receiving unit 300. (Example: COF (Chip on Film) method), etc., which is described as including all in order to help a sufficient understanding of the invention.

The solar light receiving unit 300 may include a solar cell or a heat collecting plate for collecting sunlight. In embodiments of the present invention, solar cells are preferred. A solar cell can be called a cell, and corresponds to a semiconductor that converts sunlight into electrical energy. Both single crystal and polycrystalline can be used, but the price of polycrystalline is low.

The solar light receiving unit 300 according to an embodiment of the present invention may have a module form configured by collecting a plurality of solar cells on a plate. If there are many solar cells, it is possible to receive more sunlight at the same time.

The drive motor 310 includes a motor and a drive shaft connected to the motor. The driving motor 310 according to an embodiment of the present invention is preferably a motor capable of simultaneously linear motion and rotational motion of the drive shaft, and a suction motor may be used.

The driving motor 310 is connected to one side of the fan 320 to operate the fan 320 under the control of the driving unit 330. In order to operate the fan as a solar fan under the control of the driving unit 330, the driving shaft is connected to the fan 320. Alternatively, by blocking the current applied to the motor, the drive shaft and the fan 320 are separated to freely rotate.

Therefore, the driving motor 310 according to an embodiment of the present invention blocks current and converts the kinetic energy generated by the fan 320 into electrical energy and recovers it to charge the battery. Any number can be possible.

That is, the driving motor 310 generates electric energy, that is, kinetic energy such as rotation of the drive shaft by applying electric current, but in contrast, when blocking the current, it may be possible to generate kinetic energy as electric energy in reverse.

The fan 320 connected to the drive shaft of the drive motor 310 may be separated from the drive shaft under the control of the drive unit 330, but since it can be variously designed according to the intention of the system designer, in the embodiment of the present invention It will not be specifically limited to either type.

According to an embodiment of the present invention, it is preferable to use sunlight and wind power as a power source in a state where the drive shaft and the fan 320 are connected, and when using the wind power source, the wind power source is recovered as electrical energy again. It's even better if you can charge the battery.

The fan 320 may be connected to the exhaust pipe 100 according to an embodiment of the present invention, so long as it can perform an exhaust operation. Therefore, in the embodiment of the present invention will not be particularly limited to the form as shown in FIG.

The driving unit 330 includes some or all of the sensing unit 400, the control unit 410, the solar power storage unit 420, and the motor driving unit 430, as shown in FIG. 4, wherein "includes some or all" Doing is the same as the previous meaning.

The sensing unit 400 may include various sensors such as an optical sensor, wind speed sensor, and air volume sensor. Preferably, an optical sensor and a wind speed sensor are provided so that the fan 320 is operated by wind power when the wind speed is large, and the fan 320 is operated by sunlight when the wind speed is small.

The control unit 410 performs an overall control operation of the sensing unit 400, the solar power storage unit 420, and the motor driving unit 430 constituting the ventilation unit 110. The control unit 410 controls the motor driving unit 430 by determining whether to operate the fan 320 with sunlight or wind power based on the sensing signal of the sensing unit 400. For example, if it is determined that there is sunlight or is sufficient based on the sensing signal from the sensing unit 400, the electrical energy from the sunlight received by the solar light receiving unit 300 is stored in a solar power storage unit 420 such as a battery. Order. Then, the power of the solar power storage unit 420 is provided to the motor driving unit 430 to drive the motor. Accordingly, the fan 320 operates as a solar fan.

On the other hand, if there is no or weak sunlight or a wind speed (above a reference value) is sensed based on the sensing signal of the sensing unit 400, the power of the solar power storage unit 420 applied to the motor driving unit 430 is cut off. Accordingly, the fan 320 may be operated by natural wind. At this time, when the fan 320 rotates, the control unit 410 may recover it as electrical energy and store it in the solar power storage unit 420 again.

Above all, the control unit 410 may execute a program to measure the charge amount of the electric charge stored in the solar power storage unit 420. Depending on the value of the measured charge amount, it may be possible to appropriately control the operation of storing or storing electricity. The charge amount measurement may be possible through the rate of movement of the charge. Usually, when the charge amount is large, the movement speed of the charge is fast. Velocity is calculated as the time when the electric charge moves the unit area, so the electric charge means the electric current.

The control unit 410 not only can appropriately adjust the output amount of the power to operate the fan 320 with a solar fan or a wind fan at all times, but also frequently operates during the day, but reduces the frequency at night to reduce power consumption. Can be reduced. In addition, the operation related to the operation cycle or power consumption of the fan 320 may be periodically modified through operations such as deep learning based on the date, time, and sensing data. For example, it can be installed in a specific place to collect data on the temperature and wind for a year. Through this, deep learning is performed to properly distribute power based on this, so that it is always operated with a solar fan or a wind fan.

The solar power storage unit 420 includes a battery. The solar power storage unit 420 stores electric energy provided through the solar light receiving unit 300 under the control of the control unit 410, and also provides power to the motor driving unit 430 at the request of the control unit 410. . For example, in the process of this, the solar power storage unit 420 may convert the output voltage or current, that is, convert the output voltage through an inverter or converter and output the converted voltage.

The motor driving unit 430 may include a controller that controls the driving motor. The motor driving unit 430 rotates the driving shaft by driving the motor according to a control command of the control unit 410. According to an embodiment of the present invention, a motor may be driven when sunlight is used as a power source. Alternatively, the motor driving unit 430 converts kinetic energy into electrical energy through a sensor (or an electric recovery device) electrically connected to the driving shaft when the driving shaft connected to the fan 320 is rotated by wind power without providing power to the motor. After that, it may be provided to the control unit 410. More precisely, the control unit 410 may be requested to open the path of the solar power storage unit 420 so that electrical energy is stored.

The driving motor 310 of FIG. 3 according to an embodiment of the present invention may include a control unit 410 and a motor driving unit 430 according to what kind of motor is used and in what form the system designer designed the driving motor 310 to operate. ) Can vary. However, in the exemplary embodiment of the present invention, it is sufficient if the fan 320 can operate in sunlight in a first condition (or first mode) and in wind power in a second condition (or second mode).

On the other hand, the control unit 410 according to an embodiment of the present invention is composed of a CPU and a memory as another embodiment, it may be formed by a one-chip (One-chip). The CPU may include a control circuit, an operation unit (ALU), and an instruction analysis unit, and the memory may include a ROM (ROM) or a RAM (RAM). The memory stores a program for performing an operation according to an embodiment of the present invention, and the CPU executes the stored program. By running the program, the CPU can perform the above series of operations. For example, the fan 320 may be operated by sunlight in the first mode, and the fan 320 may be operated by wind power in the second mode.

5 is a view for explaining the structure and operation principle of the ventilation device of FIG. 3 according to the first embodiment of the present invention, and FIG. 6 is a structure and operation of the ventilation device of FIG. 3 according to the second embodiment of the present invention It is a diagram for explaining the principle.

5 shows that the driving motor 310 constituting the ventilation device 110 of FIG. 3 may include at least one of a linear motor and a rotating motor. In other words, since the linear motor can linearly move the driving shaft 500 under the control of the driving unit 330 to protrude to the outside and collect it, the driving shaft is fastened to the fastening unit 321 of the fan 320 accordingly. It can be released or separated from the unit 321.

On the inner surfaces of the drive shaft and the fastening part 321 forming a part of the fan, gear-shaped threads 500 and 510 are formed in the same direction to facilitate fastening and release. For accurate fastening, the drive unit 330 may be tested to rotate the drive shaft from side to side several times at the time of insertion and then be accurately engaged with the fastening unit 321, and thereafter, a fastening operation may be performed. In other words, when the drive shaft is to be fastened to the fastening part 321, if the fastening is not properly performed, the driving part 330 can detect this and perform the above operation. The fastening can be measured by sensing the pressure applied to the drive shaft.

In addition, when the coupling of the driving shaft 500 and the fastening part 321 of the fan 320 is completed, the driving part 330 may operate the fan 320 using sunlight as a power source.

In addition, when the fastening part 321 of the drive shaft 500 and the fan 320 is separated, the fan 320 may be rotated by wind power.

Based on this, it may be desirable to be designed so that the linear motion and the rotational motion of the fan 320 can be performed in parallel. Simply connect the linear motor to the upper side of the fan 320 and operate by fastening the rotary motor to the lower side, the above operation can be easily performed.

On the other hand, Fig. 6 shows that the magnetic materials of the N-pole and the S-pole can convert the polarity by electrical principles. Suppose that the magnetic material 610a of the S pole is coated on the inner surface of the fastening portion 610 of the fan 320.

In this case, the magnetic material 600 of the N pole applied to the drive shaft is converted to have the S pole through the current or voltage applied through the coil 601. Although the coil 600 is illustrated as being wound around the driving shaft in FIG. 6, it may be understood that the coil 600 is electrically conductive to the N-pole magnetic material 600.

Therefore, when the two magnetic materials are bipolar, the driving shaft and the fan 320 generate suction force, or attraction, and when the two magnetic materials are bipolar, the driving shaft and the fan 320 generate repulsive force. Of course, the target of suction and desorption may be the fan 320. In the case of bipolarity, since the drive shaft and the fan 320 are integrated, the drive shaft of the drive motor 310 is rotated by solar power in a state of being fastened to each other, thereby rotating the fan 320.

In addition, when the drive shaft and the fan 320 are separated by repulsive force when they are of the same polarity, the fan 320 is rotated by wind power.

7 is a view showing a ventilation system according to another embodiment of the present invention.

As illustrated in FIG. 7, the ventilation system 690 according to another embodiment of the present invention may include a first ventilation device 110 ′ and a second ventilation device 700.

The first ventilator 110' may operate only with sunlight, and the second ventilator 700 may operate only with wind power. In other words, in the presence of wind, since the second ventilator 700 will always operate, the first ventilator 110' operates at a time when it is determined that the second ventilator 700 will not operate. will be. Of course, it is possible to operate both devices as much as possible, so the embodiment of the present invention will not be limited to any one operation. However, in order to operate the first ventilation device 110' and the second ventilation device 700 at all times, it is preferable to selectively operate.

Accordingly, the first ventilator 110' measures the presence or absence of wind or the amount thereof based on a sensing signal acquired through, for example, an airflow sensor, and the second ventilator 700 will not operate according to the result. When judged, the fan can be operated using sunlight or stored solar energy.

In addition, when it is determined that the second ventilator 700 does not operate properly due to a failure or the like by measuring the degree of gas or odor in the exhaust pipe 100 through a sensor, or when it is determined that more fans need to be operated, additionally The first ventilation device 110' may be operated.

In addition to the above, the first ventilator 110' according to an embodiment of the present invention can perform the operation of the ventilator 110 as shown in FIG. 3, so detailed descriptions thereof will be omitted.

8 is a flowchart illustrating a driving process of a ventilation device according to an embodiment of the present invention.

During this process, an operation of receiving light and accumulating the battery may be further performed.

In addition, the ventilator 110 discharges the odor or gas flowing through the pipe through the exhaust fan is fastened to one side of the solar receiver (S810). Here, the pipe means a poly-based PVC pipe, but a duct or a hose may also be used.

In addition, the ventilation device 110 controls the drive shaft of the motor connected to the exhaust fan to drive the exhaust fan with a power source selected from (gi) received sunlight and wind (820). The ventilator 110 rotates the drive shaft by applying a current to the motor when solar light is selected as the power source. On the other hand, when wind power is selected as the power source, the current applied to the motor is cut off.

In the process of this, the ventilation device 110 may convert kinetic energy due to the rotational motion of the drive shaft into electrical energy and store it in the battery. At this time, the ventilation device 110 measures the amount of charge of the battery, so that the battery is fully charged. ) The charging operation can be performed until it is charged. In order to measure the state of charge, it can be determined simply by measuring the movement speed of the charge. That is, the current is calculated as the amount of electric charge that moves the unit area, so if there is a large amount of electric charge, the electric charge will move rapidly, and if it is small, the electric current moves slowly. Therefore, it is possible to measure the charge amount by measuring the speed of the charge.
