In contrast, in recent years, non-Cryogenic Air Separation such as a PSA method or a hollow fiber membrane (Membrane) method, which has a simple device configuration and can reduce equipment costs, is frequently used.

Among these, the PSA method is a method of separating nitrogen and oxygen components in the air by using the selective adsorption capacity of the adsorbent such as Zeolite Molecular Sieve (ZMS), and when the air is put in the adsorption bed filled with zeolite, the zeolite is selected for adsorption.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are designated as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a configuration diagram of an oxygen generator according to an embodiment of the present invention, FIG. 2 is a view showing an embodiment of the control unit of FIG. 1, and FIG. 3 is a view illustrating a control method of the control unit of FIG.

As shown in Figures 1 to 3, the oxygen generator 1 of the present embodiment is the filtration filter 10, the compressor 20, the solenoid valve 30, the adsorption beds (40, 50), the orifice valve (60a, 60b), check valves (70a, 70b), the oxygen storage tank 80, it may be configured to include a control unit (90).

The filtration filter 10 filters the foreign substances in the external air to supply purified air to the compressor 20 through the purified air supply line 10a. The compressor 20 compresses the air supplied from the filtration filter 10 and discharges the compressed air to the solenoid valve 30.

The solenoid valve 30 connects the compressor 20 and the adsorption beds 40 and 50, distributes compressed air to two or more adsorption beds described later, and distributes air to discharge nitrogen removed from the adsorption bed. It may be a solenoid valve capable of automatic control provided with a valve. Here, the solenoid valve 30 separates the flow path connected to the compressor 20, the branched flow path connected to the pair of adsorption beds 40 and 50, and the discharge flow path of nitrogen generated in the adsorption bed, respectively, to provide high purity oxygen. Or to allow for the separation of nitrogen.

Each branched flow path of the solenoid valve 30 pushes compressed air flowing inwardly as the port opens when current is supplied to the adsorption beds 40 and 50, and when the current is cut off, the port is closed. It can work in the form.

Adsorption beds 40 and 50 adsorb nitrogen from the compressed air introduced into the solenoid valve 30 and discharge oxygen. Although not shown in detail, the adsorption beds 40 and 50 may be zeolite beds filled with powdered zeolite in a cylindrical body and sequentially arranged with a nonwoven fabric and a moisture absorbent fabric.

Adsorption beds 40 and 50 may be provided in plural, and may be provided in pairs as in this embodiment. Since each branched flow path of the solenoid valve 30 is connected to each of the pair of adsorption beds 40 and 50, the solenoid valve 30 may be supplied to the pair of adsorption beds alternately with compressed air.

When oxygen is separated using a pair of adsorption beds, the adsorption bed of the other adsorption bed can be removed from the adsorbent while the adsorption of nitrogen and oxygen separation are carried out in one adsorption bed. This allows the process to proceed continuously and repeatedly.

In addition, the solenoid valve 30 may control to discharge nitrogen from the other adsorption bed when oxygen is generated in one of the adsorption beds of the pair of adsorption beds 40 and 50.

As such, the solenoid valve 30 can control the pressure and flow rate of the compressed air supplied from the compressor 20 to the pair of adsorption beds 40 and 50, and can appropriately regulate the discharge of oxygen and nitrogen. Therefore, the purity and pressure of oxygen generated in the adsorption beds 40 and 50 can be controlled by appropriate opening and closing control of the solenoid valve 30.

It is connected to discharge the nitrogen produced in the adsorption beds (40, 50). Orifice valves (60a, 60b) can maintain the discharge pressure of the oxygen discharged through the adsorption beds (40, 50) at a low pressure, the orifice valve and the check valve is supplied to the generated oxygen and nitrogen in a predetermined direction to prevent the back flow It can be configured to.

The oxygen passing through the orifice valve is collected in the oxygen storage tank 80, the oxygen storage tank 80 may be connected to various places, that is, the indoor space of the office or home, medical equipment, automobiles and the like to supply oxygen. Nitrogen passing through the check valve is supplied to the compressor via the solenoid valve.

The control unit 90 controls the compressed air flowing into the adsorption bed 20 from the compressor 20 by selectively adjusting the opening and closing time of the solenoid valve 30 described above. The controller may include a dip switch 200 provided in the printed circuit board 100 as shown in FIG. 2.

The dip switch 200 may be mounted on the printed circuit board 100 to exchange signals with the solenoid valve 30 so that the user may variably set the opening and closing time of the solenoid valve 30. The printed circuit board may include an integrated circuit (not shown) in which a default value for opening / closing time of the solenoid valve is input.

In addition, the dip switch may include a plurality of switches so that the user can directly set the variable value in addition to the default value. For example, the dip switch may be provided with four switches in which each variable value is set, and the four switches may be configured to be operated by a user ON / OFF.

Each time value may be set to four switches. For example, variable values of 1s, 2s, 3s, and 4s may be input to the switches 1, 2, 3, and 4, respectively. Of course, the variable value of each switch is not limited to that illustrated, and can be changed as needed. In this example, since the default value is 9s (second) and the variable value can be adjusted from 0s to 10s, the change value of the opening and closing time of the solenoid valve 30 can be arbitrarily set by the user from 9 seconds to 19 seconds.

Specifically, as shown in FIG. 3, when the default value of the opening and closing time of the solenoid valve 30 is 9 s and the user turns on the first and third switches in the dip switch and the second and fourth switches are turned off, the variable value is variable. The value is 1s + 3s, totaling 4s. Therefore, the change value of the opening-closing time of the solenoid valve 30 becomes a total of 13s which adds 9s of a default value and 4s of a variable value.

When the time value is set as described above, the control unit 90 adjusts the time to open and close the solenoid valve 30 at an interval of 13 seconds while the compressed air supplied from the compressor 20 to the pair of adsorption beds 40 and 50. It is possible to control the pressure and the flow rate, so that it is possible to appropriately control the discharge of oxygen and nitrogen generated in the adsorption bed.

Since the compressed air introduced into the adsorption bed from the compressor 20 can be controlled by appropriate opening and closing control of the solenoid valve through such a control unit, the purity and pressure of oxygen generated in the adsorption bed can be controlled.

Figure 4a schematically shows an embodiment of the compressor of Figure 1, Figure 4b schematically shows another embodiment of the compressor of Figure 1, Figure 5 shows that the compressor of Figure 4 is configured in a drawer type 6A and 6B are front views illustrating internal configurations of the compressors of FIGS. 4A and 4B, respectively, and FIG. 7 is an enlarged view of a compressed air supply line among the compressor components of FIG. 6.

As shown in FIGS. 4 to 7, the compressor 20 includes a compressor 23 embedded in the case 21 and a compressor 23 for compressing air, a compressor 23 mounted thereon, and a support plate 24 capable of moving forward and backward. It may be configured to include a compressed air supply line 25 is connected to the compressor to supply compressed air to the adsorption beds (40, 50) and a nozzle unit 22 provided inside the case.

In more detail, a compressor 23 for compressing air inside the case 21 having an inner space is mounted on the drawer support plate 24 capable of moving forward and backward, and connected to the compressor to provide compressed air to the adsorption bed. Compressed air supply line 25 to be supplied is provided in the form of a coiled coil, so that the compressed air moving and moving in a spiral source at high speed is separated from air and moisture by centrifugal force, and the separated water is collected under each coil by gravity. Only the compressed air from which moisture is removed is moved to the adsorption bed, thereby preventing the compressed air containing water from moving to the zeolite of the adsorption bed.

At this time, the moisture removal unit 26 may be further connected to the compressed air supply line to discharge the moisture collected at the lower end of the coil of the compressed air supply line 25 to the outside. The water removal unit 26 has a water movement passage 26a connected to the lower end of each coil, and is connected to each water movement passage 26a, and has a drain valve for automatically opening / closing by sensing a moisture storage limit line and a limit line. It may consist of one reservoir 26b. At this time, the reservoir is not limited to this, but is preferably provided inside the support plate.

The expansion portion of the injection nozzle portion can be configured, the expansion line 22 'which is in communication with the nitrogen supply line (L) for supplying the compressed nitrogen adsorbed on the plurality of adsorption beds into the case branched from both sides from the top At the end of the expansion line, a plurality of nozzles are formed so that a plurality of nozzles are directed toward the compressor, so that nitrogen can be concentrated to be heated toward the heated compressor.

In addition, an expansion valve 75 or a thermoelectric element 76 may be further provided at a connection portion between the nozzle part and the nitrogen supply line, and the nitrogen compressed by the expansion valve is vaporized while expanding and expanding the pressure while passing through a narrow passage. In addition, the temperature of the nitrogen supplied to the nozzle unit 22 through the nitrogen supply line is further lowered by the endothermic reaction of the thermoelectric element configured to surround the nitrogen supply line. As a result, the temperature of the compressor heated in the compressor by the low temperature nitrogen supplied into the compressor can be cooled quickly.

Here, as shown in FIG. 8, the thermoelectric element 76 uses an endotherm or heat generation due to the Peltier effect. The thermoelectric element 76 is a device that generates one endotherm and the other generates heat depending on the direction of the current. Of course, the current flow direction for causing the thermoelectric element to generate an endothermic reaction from the endothermic portion attached to the nitrogen supply line may be controlled by the controller.

In addition, a heat dissipation fan (not shown) may be selectively installed on the side surface of the case 21 and the bottom surface of the support plate 24. In this case, the heat dissipation fan installed on the side of the case may serve to introduce external air into the case, and the heat dissipation fan installed on the bottom of the support plate may serve to discharge the air inside the case to the outside.

The present invention has a shower nozzle inside the compressor case, the nitrogen supplied through the nitrogen supply line is lowered to a low temperature, and the nozzle is ejected from the nozzle to the entire outer surface of the compressor, thereby overheating the computer by the compression process. Resha can be cooled quickly without running the heatsink. As a result, the malfunction of the oxygen generator can be prevented, the durability can be extended, and the noise problem caused by the operation of the heat radiating fan can be solved.

As shown in FIG. 1, the nitrogen supply line L is configured to connect the compressor with the solenoid valve 30 controlling the adsorption beds 40 and 50. By such a configuration, the low temperature nitrogen supplied to the compressor through the nitrogen supply line may be controlled by the solenoid valve 30. That is, the controller can control the cooling frequency of the compressor 20 by nitrogen while controlling the flow of nitrogen adsorbed to the adsorption beds 40 and 50 through opening and closing control of the solenoid valve 30.

In addition, the low temperature nitrogen is supplied into the case as described above to increase the temperature difference between the inside and the outside of the compressed air supply line 25 through which compressed air of high heat passes, thereby facilitating separation of moisture contained in the compressed air. There is.

A handle 24a is formed at the front of the support plate 24 to facilitate forward and backward movement of the support plate.
