Description

Gas transport device, manufacturing method of gas transport device and gas transport method

The present disclosure relates to a gas transport device having a vibrating part, a manufacturing method thereof, and a gas transport method.

In recent years, certification systems such as LEED (Leadership in Energy and Environmental Design) certification, which evaluates buildings based on health and environmental performance, and WELL certification, which evaluates buildings based on human comfort and health, have been attracting attention. In general, comfort is evaluated by a method of calculating PMV (Predicted Mean Vote) from temperature and humidity. Further, in general, the temperature and humidity in the building are adjusted so as to be the specified value of PMV which is considered to be comfortable, but personal preference is not taken into consideration. Therefore, even if the environment inside the building matches the PMV value that is considered to be comfortable, some individuals may feel uncomfortable. For example, since there are individual differences in how dryness is felt in winter, if a conventional humidification method such as vaporization, steam, or water spray is used to humidify the room, the moisture will diffuse and the humidity in the room will be diffused. Is uniform, and the comfort of multiple people in the room cannot be satisfied. As a method for solving such a problem, there is a method of transporting a gas containing water as a vortex ring to a local space where each individual is present (see, for example, Patent Document 1). The vortex ring moves while confining the fluid that rotates inside, and it is difficult for the gas to diffuse to the surroundings during transportation. Patent Document 1 discloses a technique for transporting a gas to a local space in a room by forming a vortex ring having such directivity.

Japanese Unexamined Patent Publication No. 2013-024480

However, in Patent Document 1, the pressure inside the pressurizing chamber connected to the vortex ring outlet is directly fluctuated by the diaphragm facing the pressurizing chamber to generate a vortex ring, and the gas is transported. Therefore, when the gas transported by the gas transport device is humidified air containing a large amount of water, the device disclosed in Patent Document 1 is configured such that the humidified air in the pressurizing chamber directly touches the vibrating plate. Therefore, the humidified air is dewed and water droplets are likely to adhere to the vibrating plate. When water droplets adhere to the diaphragm, the vibration is hindered and the intended pressurization chamber is not pressurized, and a good vortex ring cannot be formed, so that stable gas transportation cannot be performed.

The present disclosure has been made to solve the above-mentioned problems, and an object of the present disclosure is to provide a gas transport device capable of stable gas transport, a method for manufacturing a gas transport device, and a gas transport method.

Further, the method for manufacturing a gas transport device according to the present disclosure is the above-mentioned method for manufacturing a gas transport device, in which the outer peripheral portion of the elastic film is connected to the inner surface of the housing with an adhesive. ..
Further, the gas transport method according to the present disclosure includes a vibration step of vibrating the vibrating portion by driving the vibration generator and the vibration in the gas transport method of transporting the gas using the gas transport device. The elastic film is expanded and contracted through the vibration transmission chamber by the vibration of the portion, and the vibration is transmitted to the pressurizing chamber connected to the discharge port, and the pressurization is performed by the expansion and contraction of the elastic film. It includes a pressurizing step of pressurizing the gas existing in the room and a discharging step of discharging the gas pressurized by the elastic membrane to the outside through the discharging port.

The signal generator 22 and the power amplifier 23 are connected by a signal line 24. Further, the power amplifier 23 is connected to the vibration device 10 by a signal line 24. The vibrating device 10 includes a vibrating portion 12 installed at the rear end of the housing 14 so as to face the elastic film 13, and a vibration generator 11 that receives a signal from the power amplifier 23 and vibrates the vibrating portion 12. Have.

A closed vibration transmission chamber 17 is formed between the elastic film 13 provided in the housing 14 and the vibrating portion 12 of the vibrating device 10 installed in the housing 14. The elastic film 13 and the vibrating portion 12 are not in direct contact with each other, and the elastic film 13 and the vibrating portion 12 are arranged apart from each other. That is, the vibration transmission chamber 17 includes the elastic film 13, the vibrating portion 12 facing the elastic film 13, and the rear portion connecting the outer peripheral portion of the elastic film 13 and the outer peripheral portion of the vibrating portion 12 on the peripheral wall of the housing 14. , Formed by. That is, in the housing 14, a pressure chamber 16 opened to the atmosphere of the target space by the opening 15 is formed in front of the elastic membrane 13, and a closed vibration transmission chamber 17 is formed behind the elastic membrane 13. Has been done. It is desirable that the internal pressure of the vibration transmission chamber 17 is higher than the environmental pressure (atmospheric pressure) around the device. In the housing 14, the connection wall 143 described above is connected to the lower part of the peripheral wall portion 142 in front of the elastic film 13, and is configured to communicate the gas supply portion 50 and the pressurizing chamber 16.

The control unit 31 is connected to each of the signal generator 22, the power amplifier 23, and the gas supply unit 50 by a control line 32. The control unit 31 controls the vibration of the vibration unit 12 by controlling the signal of the signal generator 22 and the power amplification amount of the power amplifier 23. Specifically, the control unit 31 controls the waveform, magnitude, frequency, and the like of the signal generated by the signal generator 22. Further, the control unit 31 controls the amount of gas to be transported to the target space by controlling the amount of gas supplied from the gas supply unit 50 to the pressurizing chamber 16.

The control unit 31 can use a device having a storage function such as a memory, a device having a calculation function such as a CPU, or a device having both a storage function and a calculation function such as a microcomputer. The control unit 31 can also store a program in which the operation of each device is predetermined. Further, the control unit 31 stores a relational expression, a data table, or the like based on the evaluation result of the measurement performed in advance by changing various parameters. Here, the parameters are, for example, the physical properties of the gas to be transported, the surrounding environment, the size of the opening 15, the setting of each device, the region for transporting the gas, the transport amount of the gas, and the like. The settings of each device are, for example, a signal generated by the signal generator 22, an amplification amount of the power amplifier 23, a gas supply amount of the gas supply unit 50, and the like.

A human interface device such as a keyboard may be connected to the control unit 31, and a program, setting values, and the like may be input and changed to the control unit 31 via the human interface device.

A series of operations performed by the gas transport device 100 will be described with reference to FIG. First, the signal generated by the signal generator 22 is sent to the power amplifier 23. The signal amplified by the power amplifier 23 is sent to the vibration generator 11 of the vibration device 10, and the vibration unit 12 is displaced by the vibration generated by the vibration generator 11. The vibration of the vibrating portion 12 of the vibrating device 10 is transmitted to the elastic membrane 13 via the sealed vibration transmission chamber 17. The elastic film 13 expands and contracts while the outer peripheral portion 13a (see FIG. 2 described later) is supported by the housing 14. By displacing the portion including the central portion of the elastic film 13 toward the pressurizing chamber 16, the pressurizing chamber 16 is pressurized, and the gas in the pressurizing chamber 16 supplied from the gas supply unit 50 is released from the opening 15. It is released as a vortex ring and the gas is transported. At this time, the signal of the signal generator 22 and the power amplification amount of the power amplifier 23 are controlled by the control unit 31, and the displacement amount due to the vibration of the vibration unit 12 is controlled. Further, the control unit 31 controls the amount of gas supplied from the gas supply unit 50 to the pressurizing chamber 16.

Next, the configuration of the gas transport device 100 will be described in detail. The signal generator 22 can generate a signal having an arbitrary waveform. The signal waveform is preferably a rectangular pulse wave. Further, the frequency of the signal waveform is the resonance frequency of the vibration generator 11 in the state of being incorporated in the gas transport device 100, or the resonance frequency of the vibration generator 11 alone in the state of not being incorporated in the gas transport device 100. It is desirable to set. Alternatively, it is desirable that the vibration generator 11 is set so as to include a large number of frequency components having a maximum value or a minimum value of the impedance in the state of being incorporated in the gas transport device 100. Alternatively, it is desirable that the vibration generator 11 is set so as to include a large amount of resonance frequency components at the maximum value or the minimum value of the impedance of the vibration generator 11 alone, which is not incorporated in the gas transport device 100.

As the vibration device 10, an electromechanical converter that converts the electric energy of an electric signal into vibration, which is mechanical energy, is used. A typical example of an electromechanical transducer is a speaker of an audio device. The speaker uses the current flowing through the coil and the action of a magnet to convert an electrical signal into mechanical vibration. Generally, a speaker is composed of, for example, a cone-type or horn-type diaphragm, a coil portion to which the diaphragm is adhered, a support portion that supports the coil portion via a spring, a magnet installed on the support portion, and the like. To. When a current flows through the coil, a magnetic field is generated, and a force acts on the coil due to the generated magnetic field and the magnetic field of the magnet to vibrate the coil, and the vibrating plate adhered to the coil vibrates. When a speaker is used as the vibration device, the coil is the vibration generator 11 and the diaphragm constitutes the vibration unit 12. Generally, a wide variety of materials such as metal, polymer material, ceramics, or paper are used for the diaphragm of the speaker. As the vibrating device 10, a piezoelectric element, which is one of the electromechanical transducers, can be used instead of the speaker. Generally, the piezoelectric element has a piezoelectric ceramic, an electrode provided on the piezoelectric ceramic, and a metal plate bonded to the piezoelectric ceramic, and is configured to vibrate the metal plate by applying a voltage to the piezoelectric ceramic. ..

The power amplifier 23 amplifies the signal output from the signal generator 22. The amount of amplification is arbitrary, but it is desirable to adjust it so that it is equal to or less than the allowable input power of the vibration generator 11.

It is desirable that the elastic membrane 13 is a thin film that is connected to the housing 14 without slack and has elasticity and elasticity with a thickness of 1 mm or less. Examples of the material of the elastic film 13 include a thin film of a film-like polymer compound.

FIG. 2 is an explanatory diagram showing the principle of generating a vortex ring of the gas transport device according to the first embodiment. In the figure, the width direction of the gas transport device 100 is represented by the arrow X direction. The vibration transmission chamber 17 has a closed structure. In order to seal the vibration transmission chamber 17, the boundary portion between the vibrating portion 12 and an arbitrary surface of the housing 14 and the boundary portion between the elastic film 13 and the peripheral wall portion 142 of the housing 14 are all the boundary portions. Over the circumference, it is adhered and fixed with, for example, a resin adhesive. That is, by connecting the outer peripheral portion 13a of the elastic membrane 13 to the inner surface of the housing 14 with an adhesive or the like, the gas transport device 100 having a sealed vibration transmission chamber 17 can be manufactured. Although the case where the adhesive is used has been described, the outer peripheral portion 13a of the elastic film 13 and the inner surface of the housing 14 are brought into close contact with each other to prevent gas from entering and exiting between the pressurizing chamber 16 and the vibration transmission chamber 17. The configuration is not limited to the adhesive.

As a result, when the gas containing water is transported by using, for example, the humidifying unit 51, the gas containing water does not come into contact with the vibrating unit 12, so that the adhesion of water due to dew condensation or the like on the surface of the vibrating unit 12 is suppressed. .. Therefore, the vibration of the vibrating unit 12 is not hindered, the vibration efficiency of the vibrating unit 12 does not decrease, the pressure fluctuation is stably applied to the pressurizing chamber 16, and stable gas transportation becomes possible. Further, by providing such an elastic film 13 on the housing 14, it is possible to prevent water droplets from adhering to the vibrating portion 12, so that the price of the device is higher than that in the case where the vibrating portion 12 is specially waterproofed. Can also be suppressed.

As for the vibration of the vibrating unit 12, the vibration of the entire surface of the vibrating unit 12 is converted into the pressure fluctuation of the vibration transmission chamber 17. That is, the vibration of the entire surface of the vibrating portion 12 is concentrated in the central portion of the elastic film 13. The elastic film 13 is centered by the pressure concentrated by the vibration of the vibrating portion 12 on the central portion of the elastic film 13 fixed to the inner surface of the peripheral wall portion 142 of the housing 14 at the outer peripheral portion 13a and provided without slack. The part easily expands and contracts as the peak of vibration displacement. Therefore, the vibration displacement at the center of the elastic film 13, that is, the reciprocating distance due to the vibration is larger than the vibration displacement at any point on the vibration surface of the vibration unit 12. Therefore, by having the vibration transmission chamber 17 and the elastic membrane 13 described above, a signal to the vibration generator 11 necessary for generating a pressure fluctuation inside the pressurizing chamber 16 that discharges a desired gas from the opening 15 is generated. Energy can be reduced and energy saving effect can be obtained.

The gas supply unit 50 supplies the gas to be conveyed to the pressurizing chamber 16 of the housing 14. For example, when transporting a gas containing water, a humidifying device such as an ultrasonic type or a heating type is used for the gas supply unit 50. When transporting a dry gas, a compressor type or desiccant type dehumidifying device is used for the gas supply unit 50. When transporting a specific gas such as oxygen, a device for generating the specific gas is used in the gas supply unit 50.

The housing 14 constitutes the pressurizing chamber 16, and any material can be used. The material of the housing 14 is preferably a material that is resistant to the gas to be transported, and the surface on the pressure chamber 16 side is thin-film, such as a material having a function of retaining or eliminating charges in the transported gas. It is also possible to use the one coated by the above. Further, the housing 14 may be made of a material that reduces noise generated by the vibrating portion 12 of the vibrating device 10, the elastic film 13, and the like.

The opening 15 is a hole of any shape and any size made in the housing 14 in order to release the gas of the pressurizing chamber 16 as a vortex ring. Regardless of the shape of the opening 15, the released vortex ring becomes circular with the passage of time. Therefore, it is desirable that the shape of the opening 15 is circular as shown in FIG. 2 to be described later. The size of the opening 15 is determined by the vibration displacement of the elastic membrane 13, that is, the amount of pressure fluctuation of the pressurizing chamber 16, the transport distance of the gas, the viscosity of the transported gas, and the like.

FIG. 2 is an explanatory diagram showing the principle of generating a vortex ring of the gas transport device according to the first embodiment. The principle of vortex ring generation and gas transport will be described with reference to FIG. For simplification, it is assumed that the opening 15 has a circular shape with a diameter D and an area S, the elastic membrane 13 has a rectangular shape with an area A, and the elastic membrane 13 is uniformly displaced in the plane.

In FIG. 2, when an electric signal is input to the vibration generator 11 of the vibration device 10, a force F0 is applied to the vibration unit 12 to displace it. Since the vibration transmission chamber 17 is hermetically sealed, when the vibration portion 12 is displaced toward the elastic film 13, the volume of the vibration transmission chamber 17 becomes smaller, so that the vibration transmission chamber 17 is pressurized and the elastic film 13 receives the force F. The pressure chamber 16 is pressurized by shifting forward and reducing the volume of the pressure chamber 16. Then, the gas inside the pressurizing chamber 16 is discharged from the opening 15.

The time ΔT at which the pressure in the pressurizing chamber 16 changes is as short as 1 second or less. As shown in FIG. 2, assuming that the displacement amount of the elastic membrane 13 in the depth direction (arrow Y direction) is ΔY, the volume change amount ΔV in the pressurizing chamber 16 is ΔV = AΔY. Further, assuming that the rate at which the gas 59 is discharged from the opening 15 is L / ΔT, a cylindrical mass of gas 59 having a bottom area of S and a height of L from the bottom surface is discharged from the opening 15. The volume is SL. The columnar gas mass released from the opening 15 changes its shape due to the force received, and after being released from the opening 15, becomes an annular shape (also called a donut shape or a torus shape) and translates. do. In the following description, such an annular gas mass that moves in translation may be referred to as a vortex ring. Here, the formation state of the vortex ring changes depending on the physical properties such as the viscosity of the gas to be conveyed and the environmental factors such as the ambient temperature. In addition, the values of the diameter D, the force F, the force F0, and the like of the opening 15 are determined.

As for the motion state of the vortex ring discharged from the opening 15, the smaller the diameter D of the opening 15, the larger the force F applied to the elastic film 13, and the smaller ΔT, the higher the traveling speed of the vortex ring. The vortex ring released into the space slows down due to air resistance or the like, and eventually becomes stationary, the gas constituting the vortex ring diffuses into the surrounding space, and the vortex ring disappears. Since the vortex ring moves in the direction in which the rotating fluid is trapped inside and is discharged, the gas is less likely to diffuse to the surroundings during movement than a gas mass having a uniform velocity inside and outside, and it goes far. Can be reached.

From the above, by setting parameters such as the diameter D of the opening 15 and the force F0 applied to the vibrating portion 12 in advance, it is possible to transport a specific gas to a specific region. The diameter D of the opening 15, the force F0 applied to the vibrating portion 12 required to vibrate the elastic film 13 through the vibration transmission chamber 17, the waveform, power and frequency of the signal generated by the signal generator 22, and the power amplifier 23. The amplification amount of the above, the amount of gas supplied by the gas supply unit 50, and the like are determined in advance. It is desirable that these values are set in advance based on the experimental results by transporting the gas to be transported to the target space by an experiment or the like.

As described above, the gas transport device 100 of the first embodiment has a housing 14 having a gas discharge port (opening 15) and a pressurizing chamber 16 connected to the discharge port formed therein, and vibration. The device 10 and the elastic film 13 are provided. The vibrating device 10 has a vibrating unit 12 that vibrates and a vibration generator 11 that vibrates the vibrating unit 12, and the vibrating unit 12 is installed at an arbitrary position of the housing 14 via the pressurizing chamber 16. The elastic membrane 13 is arranged between the pressurizing chamber 16 and the vibrating portion 12, and has an outer peripheral portion 13a connected to the inner surface of the housing 14. Then, inside the housing 14, between the vibrating portion 12 and the elastic membrane 13, the wall portion between the vibrating portion 12 and the outer peripheral portion 13a of the elastic membrane 13 in the housing 14, the vibrating portion 12, and the elasticity. A closed vibration transmission chamber 17 is formed by being surrounded by the membrane 13.

As a result, water droplets due to dew condensation on the humidified air in the pressurizing chamber 16 do not adhere to the vibrating portion 12 of the vibrating device 10, a decrease in vibration efficiency can be suppressed, and stable gas transportation can be performed by a good vortex ring. Further, it is possible to prevent deterioration of the vibrating portion 12 of the vibrating device 10 due to water droplets. Therefore, it is not necessary to apply waterproofing to the vibrating device 10, a general speaker or the like can be used as the vibrating device 10, and the price of the gas transport device 100 can be reduced. Further, since the vibration of the entire surface of the vibrating portion 12 of the vibrating device 10 is concentrated in the central portion of the elastic membrane 13 via the vibration transmission chamber 17, the elastic membrane 13 having a larger amplitude than the vibrating portion 12 of the vibrating device 10 is provided. By pressurizing the gas in the pressurizing chamber 16 through the pressurizing chamber 16, an energy saving effect can be obtained.

Actually, when the inventors manufactured a gas transport device designed as described above and visually confirmed the flight distance of the humidified air using the humidified air generated by the ultrasonic humidifier as a specific gas, the vortex ring was found. It was confirmed that it can be humidified by translating for 1 meter or more, transporting water to a specific area. Further, the inventor has configured the gas transport device 100 in which the humidified air is not brought into contact with the vibrating portion 12 by the closed vibration transmission chamber 17, in which the vibration efficiency of the vibrating portion 12 does not decrease and the gas is stably transported with low energy. It was confirmed that this can be done and that the deterioration of the vibrating portion 12 can be suppressed.

Further, the gas transport device 100 of the first embodiment is connected to the vibration generator 11 via a signal line 24, and has a drive circuit 20 for driving the vibration generator 11 and a control unit 31 for controlling the drive circuit 20. Be prepared. The drive circuit 20 includes a signal generator 22 that generates a signal and a power amplifier 23 that amplifies the signal generated by the signal generator 22. The vibration generator 11 converts the electrical energy of the signal input from the drive circuit 20 into mechanical energy.

Thereby, by controlling the vibration of the vibrating unit 12, the pressure applied to the gas in the pressurizing chamber 16 can be adjusted so that the released gas forms a vortex ring. Further, as the vibration device 10, an electromechanical converter such as a general piezoelectric element and a speaker can be used, and the price of the gas transport device 100 can be reduced.

In the signal generator 22, an arbitrary waveform such as a sine shape or a rectangular shape is continuously generated to repeatedly vibrate the vibrating portion 12, repeat through the transmission chamber, and vibrate the elastic film 13 to be substantially continuous. The gas can be transported to the target space. Further, in the signal generator 22, when an arbitrary waveform such as a sine shape or a rectangular shape is generated intermittently or intermittently, the vibrating portion 12 is vibrated at an intended time interval, and the elastic film 13 is passed through the transmission chamber. Can be vibrated to intermittently or intermittently transport gas to the target space. At this time, the amount of gas transported can be adjusted by controlling the length of ON and OFF of the waveform (so-called duty ratio).

In the gas transport device 100, when the amount of gas supplied from the gas supply unit 50 to the pressurizing chamber 16 exceeds the ability to release gas from the opening 15 due to the pressure fluctuation of the pressurizing chamber 16 due to the vibration of the elastic film 13. The gas flows out from the opening 15 without forming a vortex ring. Further, if the gas is continuously supplied from the gas supply unit 50 to the pressurizing chamber 16 when the waveform is OFF, the gas flows out from the opening 15 without forming a vortex ring. The gas flowing out from the opening 15 without forming a vortex ring is more likely to diffuse than the vortex ring, and the reach is shortened. In the situation where the gas flows out from the opening 15 without forming a vortex ring, the operation of these devices is controlled by the control unit 31 so that the signal generator 22, the power amplifier 23, and the gas supply unit 50 are interlocked with each other. By doing so, it can be prevented.

Further, since the control unit 31 has a storage function, the optimum equipment configuration in a plurality of states for each of the region for transporting gas, the amount of gas to be transported, the surrounding environment such as temperature, the gas to be transported, and the like in advance. By deciding and storing it in a relational expression, etc., it is possible to respond to changes. For example, when changing the region for transporting gas or changing the amount of gas to be transported, the setting of each device is set using the relational expression stored in advance according to the physical properties of the gas to be transported or the change in the surrounding environment. Can be changed at any time to change the region for transporting gas, the amount of gas transported, and the like. Specifically, the signal generated by the signal generator 22, the amplification amount of the power amplifier 23, and the gas supply amount of the gas supply unit 50 are changed at any time. Further, the size of the opening 15 can be changed to change the range for transporting the gas or the amount of the gas to be transported.

FIG. 3 is an explanatory diagram showing a gas transport method using the gas transport device according to the first embodiment. A gas transport method for transporting gas using the gas transport device 100 will be described with reference to FIG. The gas transport method includes a humidification step of humidifying the supplied gas and a gas supply step of supplying the gas to be transported. Further, the gas transport method includes a signal processing step of processing a signal, a vibration step of generating vibration, a vibration transmission step of transmitting vibration, a pressurizing step, and a discharging step of discharging gas.

In the humidification step, the humidifying unit 51 humidifies the gas supplied to the pressurizing chamber 16 (step ST101). In the gas supply step, a predetermined amount of gas is supplied to the pressurizing chamber 16 by the gas supply unit 50 (step ST102).

In the signal processing step, the drive circuit 20 processes the signal for driving the vibration generator 11 (step ST103). Specifically, first, a signal generation step of generating a signal by the signal generator 22 is performed, and then a signal amplification step of amplifying the signal by the power amplifier 23 is performed.
