The O ₂ generation unit 15 sucks room air and discharges high-concentration oxygen, and discharges N ₂ generated from the heat of the TE cooler and the vacuum pump and the oxygen-enriched film. The internal structure of the O ₂ generation unit 15 will be described in detail with reference to FIG.
[0034]

[0035]
Next, the flow of air until high concentration oxygen is discharged by the oxygen concentrator 10 will be described. First, room air 18 is sucked from the left side of the O ₂ generation unit 15 of the oxygen concentrator 10 by a vacuum pump. In the O ₂ generation unit 15, high-concentration oxygen air is discharged to the TE cooler through the oxygen-enriched film, and the humidity of the high-concentration oxygen air is eliminated. The high-concentration oxygen air from which moisture has been removed is discharged from the air connector 24. Further, the heat of the TE cooler and the vacuum pump is discharged from the first fan 152 of the O ₂ generation unit 15, and N ₂ discharged from the second fan 153 by the oxygen-enriched film is discharged. It should be noted that the arrangement of each component in the O ₂ generation unit 15 and the flow rate and direction in discharging high-concentration oxygen air, discharging heat, and discharging N ₂ are not limited to the above, but also discharging heat, N ₂ Other arrangements can be applied as long as the resistance in the flow path is minimized so that the flow rate and direction in the discharge of air is substantially equal to the flow rate and direction of the sucked room air. As described above, by arranging the resistance in the flow path to a minimum, it is possible to efficiently discharge the optimum high-concentration oxygen air.
[0036]
In this way, the indoor air sucked by the vacuum pump in the O ₂ generation unit 15 is discharged from the oxygen-enriched film, and the high-density oxygen air is cooled by the TE cooler to condense the moisture. By eliminating moisture in the air of high-density oxygen, the optimal high concentration that eliminates moisture without taking measures to maintain the oxygen concentrator 10 in the best condition, such as draining the tube of the headset Oxygen air can be discharged.
[0037]
Next, the internal structure of the O ₂ generation unit 15 will be described.
[0038]
FIG. 2 is a block diagram showing the inside of the O ₂ generation unit of the present invention. In FIG. 2, the O ₂ generation unit 15 has two spaces, a cool side and a hot side, and is opposite to the cooling surface of the pre-filter 150, the first fan 152, and the TE cooler 155 that serve as a suction port for the indoor air 160.

A vacuum pump 156, a second fan 153 that discharges N ₂ air 162, and a ventilation port 157 that discharges hot-side hot air 163. The TE cooler 155 is composed of a Peltier element, and the heat generating surface of the TE cooler 155 is cooled by the heat sink 154.
[0039]
First, on the cool side, the room air 160 is sucked from the pre-filter 150 by the driving of the vacuum pump 156, and the high-concentration oxygen air discharged through the oxygen-enriched film 151 is supplied to the dehumidifier 158. In the dehumidifier 158, the high-concentration oxygen air is cooled by the TE cooler 155, and the moisture is masked by the condensation of moisture. The high-concentration oxygen air masked with moisture is discharged from the discharge port 161. At this time, the N ₂ air 162 discharged from the second fan 153 through the oxygen-enriched film 151 is discharged. On the hot side, the heat generated by driving the heat sink 154 and the vacuum pump 156 is cooled by the indoor air 160 sucked from the first fan 152, and discharged from the ventilation port 157 as hot air 163.
[0040]
As described above, the high-concentration oxygen air discharged through the oxygen-enriched film 151 is cooled in the dehumidifier 158 by the TE cooler 155, and the moisture condenses to mask the moisture. As a result, it is possible to discharge the optimum high-concentration oxygen air from which moisture has been removed without performing a procedure for maintaining the oxygen concentrator 10 in the optimum state, such as draining the tube of the headset.

Water drops 167 are generated on the installation surface 155. The high-concentration oxygen air 166 masked with moisture is discharged through the pipe 61. Further, the water droplet 167 accumulated in the dehumidifier 158 is discharged from the discharge port 168. Thus, by passing the high-concentration oxygen air from the oxygen-enriched film 151 through the dehumidifier 158, moisture can be excluded and the oxygen concentration can be further increased.
[0042]
FIG. 3B is a filter equivalent circuit diagram illustrating the noise mask function of the dehumidifier 158. In FIG. 3B, the dehumidifying device 158 has a mechanical low-pass filter equivalent circuit in which the cross-sectional area of the input side pipe 60 and the output side pipe 61 is the resistance R, and the capacity of the dehumidifying device 158 is C. Yes. Here, f _C = πLCR / 2, L = 8ρ / πr ² , C = 40 × 40V10 = 16 Cm ² , and R = 8 μ / πr ² are assumed to constitute a primary acoustic filter. Therefore, when the dehumidifier 158 forms a mechanical low-pass filter, the pulsation generated when the vacuum pump 156 is sucked can be smoothed and reduced, that is, the vibration generated by the driving of the vacuum pump 156 can be masked.
[0043]
Next, power supply of the oxygen concentrator 10 will be described. FIG. 4 is a block diagram showing the power supply of the oxygen concentrator of the present invention. In FIG. 4, the AC / DC power supply device 16 of the oxygen concentrator 10 is supplied with power (100 V) from the AC adapter 30, and is controlled by the CPU 37 via the 6 V power terminal 32 and the 12 V power terminal 33. Power is supplied to the configuration. The 6V power supply terminal 32 is connected to a temperature sensor 35, a humidity sensor 36, a CPU 37, and a transistor switch 41 connected to the imitation bubble generating device 12, and power is supplied to each component. The 12V power supply terminal 33 is connected to the transistor switch 41 connected to the vacuum pump 156, the TE cooler 155, the negative ion electrode 14, the first fan 152, and the second fan 153, and power is supplied to each component.
[0044]
The CPU 37 is supplied with power from the power supply terminal 32 and is connected to the temperature sensor 35 and the humidity sensor 36, and via the transistor switch 41, the vacuum pump 156, the TE cooler 155, the negative ion electrode 14, the first fan 152, and the second fan 153, connected to the imitation bubble generator 12. The CPU 37 controls the power supply ON / OFF of the connected vacuum pump 156, TE cooler 155, negative ion electrode 14, first fan 152, second fan 153, and imitation bubble generator 12 using the transistor switch 41. The CPU 37 supplies a signal to the transistor switch array 38 based on the signals supplied from the temperature sensor 35 and the humidity sensor 36. The transistor switch array 38 supplies a signal to the LED panel board 39 and the light-up LED 40 based on the signal supplied from the CPU 37. The LED panel board 39 displays temperature, humidity, oxygen concentration to be discharged, and the like based on the supplied signal. Based on the signal supplied to the light-up LED 40, the power supply for lighting up the imitation bubble generator 12 is turned on and off.
[0045]
In this way, the oxygen concentrator 10 is driven under the control of the CPU 37 to discharge high-concentration oxygen masked with oxygen, and the imitation bubble generator 12 is driven to remove high-concentration oxygen air excluding moisture. While discharging, the noise due to the drive of the vacuum pump of the oxygen concentrator can be masked by the sound generated by the imitation bubbles. Since the vacuum pump 156 can be driven by the power from the 12V power terminal 33, derivative development such as improvement to a device that can be mounted on a vehicle is facilitated.
[0046]
Next, the function of the imitation bubble generator 12 will be described. FIG. 5 is a diagram for explaining the concept of masking the noise of the vacuum pump by the sound generated by imitation bubbles. The graph shown in FIG. 5 shows noise characteristics with the vertical axis representing acoustic power (dB) and the horizontal axis representing frequency (Hz). FIG. 5A is a graph of the characteristics of noise generated during suction by the vacuum pump 156, and shows high frequency noise. FIG. 5B is a graph of noise characteristics when bubbles are generated by the imitation bubble generator 12, and shows low-frequency noise. FIG. 5C is a graph showing the noise generated when the vacuum pump 156 is sucked (FIG. 5A) and the noise generated when bubbles are generated by the imitation bubble generator 12 (FIG. 5B). is there. FIG. 5D shows a combined noise characteristic of the noise of the vacuum pump 156 and the noise of the imitation bubble generator 12. Since the high frequency noise of the vacuum pump 156 is masked by the low frequency noise of the imitation bubble generator 12, the noise is reduced as a whole as shown in FIG. In this way, the noise generated during the suction of the vacuum pump 156 can be masked by the bubble generation sound of the imitation bubble generator 12.
[0047]
Next, noise countermeasures for the oxygen concentrator 10 will be described. FIG. 6 is a diagram for explaining the configuration of the noise countermeasure of the oxygen concentrator. In FIG. 6, the oxygen concentrator 10 is provided with rubber feet 70 at predetermined locations on the bottom surface of the main case 9, for example, at four corners of the bottom surface. Further, rubber feet 70 are installed at two points on the bottom surface of the O ₂ generation unit 15 and the lower portion of the vacuum pump 156. Therefore, vibration and noise due to the driving of the vacuum pump 156 can be buffered by the rubber feet 70. Further, by forming the outer wall thickness of the main case 9 to 3 mm or more, or by attaching a sound absorbing material (urethane-based porous material) to the inner wall of the O ₂ generation unit 15, vibration and noise due to driving of the vacuum pump 156 are absorbed. Can be buffered.
[0048]
Next, the installation position of the headset 25 and the configuration of the headset 25 will be described.

It is the figure which looked at the apparatus 10 from the back front. When the oxygen concentrator 10 is not used, the headset 25 is installed on a hook 26 provided on the back surface of the oxygen concentrator 10. Thus, by storing the headset 25 on the hook 26 provided at the rear of the oxygen concentrator 10, the headset 25 can be stored compactly in a position that is not visible to the user without taking up space. The appearance of the oxygen concentrator can be shown better.
[0049]

In FIG. 8, a headset 25 connects a nozzle 28 through which high-concentration oxygen air is discharged, a headphone 27 that outputs sound such as music, an oxygen tube 70 and the nozzle 28, and fixes the headphone 27. The fixing unit 69 and an oxygen tube 70 that supplies high-concentration oxygen air to the nozzle 28 are configured.

In this way, by providing the headset 25 with the aroma basket 67 in the path of the oxygen tube 70, it is possible to discharge molecules of aroma oil together with high-concentration oxygen air to give the user a relaxing effect. Further, by outputting music that the user can relax from the headphones 27, the relaxation effect can be further enhanced without hearing the noise generated from the oxygen concentrator 10.
[0051]
Thus, the oxygen concentrator 10 of the present invention discharges high-density oxygen air from the indoor air sucked by the vacuum pump by the oxygen-enriched film 151, cools the high-density oxygen air, and condenses moisture. By having the heat sink 154, the TE cooler 155, and the dehumidifying device 158 that eliminate the moisture in the high-density oxygen air, the high-concentration oxygen air that excludes the moisture is discharged, and the noise caused by the driving of the oxygen concentrator is masked.
