The oxygen concentration sensor 78 may be located at any place desired by the user and may be fixed to the control panel 12 according to an embodiment. In addition, as described below, the control panel 12 includes a display unit and an operation unit.

In order to transmit the signal between the main body 15 and the control panel 12 and the oxygen concentration sensor 78, the transmitter 101 transmits the detected oxygen concentration to the control panel 12 in the oxygen concentration sensor 78. ), The control panel 12 is provided with a receiving unit 103 for receiving oxygen concentration, and a transmitting unit 105 for generating a control signal for controlling the main body 15. In addition, the main body 15 is provided with a receiving unit 107 that receives a control signal from the control panel 12.

The signal transmission method between the oxygen concentration sensor 78 and the control panel 12 and the main body 15 can be implemented in any known wired or wireless manner.

As a result, in the oxygen generator 10 of the present invention, the main body 15 generates oxygen, and the control panel 12 controls the oxygen generation amount of the main body 15 and displays the current oxygen concentration in the air. In addition, the oxygen concentration sensor 78 detects the oxygen concentration in the air so that the display unit of the control panel 12 displays the oxygen concentration.

2 and 3 are some views for explaining an example of the electricity supply method of the oxygen generating device according to the present invention.

Basically, the oxygen generator 10 according to the present invention may use a household alternating current (for example, alternating current 110V or 220V). That is, the controller 14 constituting the main body 15 and the pump or heater to be described later controlled by the controller operate at an AC 110V or 220V. To this end, the controller 14 in the main body 15 is configured to receive external electricity directly through the power supply line 83 and the connector 81a. The connector 81a is a known plug that can be directly plugged into a wall outlet (not shown) as shown in Figs. 25A or 25B.

FIG. 2 is a diagram illustrating an oxygen generator 10 connected to a power supply for generating a direct current, and the power supply is an example of a cigar jack port 82 of an auto.

Referring to the drawings, it can be seen that the main body 15 is connected to the cigar jack port 82 through an inverter 80, a connector 81a coupled to the inverter 80, and a power line 83. .

The inverter is a known converter that converts DC 12V into AC 110V or 220V and converts DC 12V into AC 110V or 220V and transmits the same to the controller 14. As a result, the oxygen generator 10 according to the present invention can operate by receiving electricity supplied from the cigar jack port 82.

In FIG. 2, the inverter 80 used to supply electricity to the main bodies 15a and 15b is installed outside the main bodies 15a and 15b, whereas the inverter 80 is shown in FIG. It is provided inside 15c and 15d.

That is, as shown in FIG. 3, the inverter 80 is incorporated in the main bodies 15c and 15d. The inverter 80 is connected to the controller 14 inside the main bodies 15c and 15d. In addition, the controller 14 further includes a power line 83 and a connector 81a extended to the outside so as to directly receive home AC electricity from the outside.

Meanwhile, the cigar jack port 82 and the inverter 80 are connected through a power line 83. Therefore, the direct current electricity supplied from the cigar jack port 82 is supplied to the inverter 80 in the main body 15 through the power line 83, and is converted into alternating current by the inverter and then supplied to the controller 14. The power line 83 connected to the inverter 80 can be connected and disconnected by the connector 81b. The connector 81b separates the connector 81b as a known connecting means so that the main bodies 15c and 15d can be moved to a place other than the vehicle.

As a result, the main body 15 of the oxygen generator 10 shown in FIG. 3 is provided with two connectors 81a and 81b. The two connectors are selectively used. One connector 81a is a plug that is inserted into an outlet, for example, to directly receive an external alternating current, and the other connector 81b uses a direct current of the cigar jack port 82. Connector to receive.

4A to 6B schematically illustrate a plurality of examples in which the first and second embodiments of the oxygen generating device according to the present invention are applied to a vehicle.

4A, 5A, and 6A illustrate an oxygen generator having a power supply system of the type shown in FIG. 2, and FIGS. 4B, 5B, and 6B show oxygen having a power supply system of the type shown in FIG. 3. The generator is shown.

The main body 15a of the oxygen generator 10 receives the outside air through the air inlet pipe 16, and passes the received air through the oxygen separator 38, which will be described later, to separate oxygen from the air and at the same time. The separated oxygen has a basic operating mechanism for supplying it to the required place through the oxygen discharge pipe 18.

Of course, the installation position of the main body 15a varies depending on the vehicle model. For example, a truck may be installed in the rear loading bin. In addition, the control panel 12 is located close to the driver's surroundings so that the driver can easily operate.

The main body 15a is connected to the cigar jack port 82 through the power supply line 83, the inverter 80, and the connector 81a. Therefore, the main body 15a operates by receiving electricity converted from direct current to alternating current by the inverter 80.

In addition, since the main body 15a includes the components in one case 11 as described below, the connector 81a is separated from the inverter 80 and the oxygen discharge pipe 18 is connected to the oxygen supply line 24. If the connector 92 to be connected to the) is separated, the handle 58 of the case 11 may be grasped to lift the main body 15a from the trunk and move it to another arbitrary place.

The air inlet pipe 16 is connected to the pumps 36 and 48 which will be described later in the case 11 and guides outside air into the case 11. In addition, the oxygen discharge pipe 18 is connected to the oxygen supply line 24 by the connector 92 and supplies oxygen generated in the main body 15a to a desired place through the oxygen supply line 24.

In addition, the oxygen discharge pipe 18 is further provided with a direction discharge portion (86).

In addition, the condensate drain pipe 22 is a pipe connected to the condensate trap (42 in FIG. 8) as shown in Figure 8 and below to discharge the condensate generated when oxygen is generated to the outside.

On the other hand, the oxygen concentration sensor 78 is a known sensor for detecting the oxygen concentration in the room as the installation position can be determined by the head height of the person, as shown in the sun visor (sunvisor) of the upper front as shown in Figure 6a and 6b It can also be located.

The oxygen concentration sensor 78 is wired or wirelessly connected to the control panel 12 to display the oxygen concentration of the current room through the display window 70 of the control panel 12. Of course, the oxygen concentration sensor 78 may be provided in plurality.

The control panel 12 includes a display unit 12a and an operation unit 12b. The display unit 12a displays the oxygen concentration detected by the oxygen concentration sensor 78 through the display window 70 and is also connected to the operation unit 12b to press the desired concentration input buttons 72 and 73 of the operation unit. When pressed, display the contents. A liquid crystal display device may be used as the display means of the display unit 12a.

The display window 70 indicates the current indoor oxygen concentration detected by the oxygen concentration sensor 78 to provide a reference for the driver to increase or decrease the amount of oxygen generated by the controller 14.

In particular, the oxygen concentration displayed on the display window 70 is expressed as a percentage. That is, the numerical value expressed on the display window 70 is a calculated value of (current oxygen concentration in the room / desired oxygen concentration of the driver) * 100. Here, the oxygen concentration desired by the driver is a value previously input to the controller 14 through the desired concentration input buttons 72 and 73 of the operation unit 12b.

Thus, for example, if the oxygen concentration of the room desired by the driver is 20.9% and the concentration of the room detected by the oxygen concentration sensor 78 is 20.0%, the number 96 is displayed on the display window 70 because the calculated value is 96%. Is displayed.

Similarly, if the actual oxygen concentration in the room is 21.7%, the displayed number will be 104%, indicating that the number is over 100.

Eventually, if the displayed number is over 100, the actual oxygen concentration is higher than the oxygen concentration desired by the driver. If the number is less than 100, the actual oxygen concentration is lower than the oxygen concentration desired by the driver. Therefore, the driver can easily understand the state of the oxygen concentration and take appropriate action. It becomes possible.

Although the operation unit 12b may be configured to be combined with the display unit 12a as in the present embodiment, the display unit 12a and the operation unit 12b may be separately configured according to embodiments. to be.

The operation part 12b is wired or wirelessly connected to the receiving part 107 of the main body 15a to allow the controller 14 to control the amount of oxygen generated from the oxygen separator 38 as well as a condensate drain valve (Fig. 1). 8, 44).

A desired concentration input button 72, 73, a warning lamp 74, a condensate discharge button 76, a set button 84 and a reset button 85 are provided on the front surface of the operation unit 12b.

The desired concentration input buttons 72 and 73 are input means for inputting the oxygen concentration desired by the driver to the controller 14. As the desired concentration input buttons 72 and 73 are pressed, numbers are displayed on the display window 70 to increase or decrease the numbers so as to set the desired concentration.

In addition, the set button 84 is a button for storing and setting the number determined by the desired concentration input buttons 72 and 73 so that the controller 14 stores the desired density. The reset button 85 is a button which is pressed to change the set number again. After pressing the reset button 85, the desired concentration input buttons 72 and 73 may be pushed up or down.

The circuit configuration including the desired concentration input button 72, 73 or the set button 84 and the reset button 85 can be implemented by any person skilled in the art according to the basic circuit theory, and as long as it provides the same function. Of course, it can be changed in various ways.

The warning lamp 74 is a lamp indicating that the condensate in the condensate trap (42 in FIG. 8) to be described later should be discharged. For example, when the condensate level reaches the terminal (52 in FIG. 14), other times Is turned off.

The condensed water discharge button 76 provided on the side of the warning lamp 74 is a button for opening the condensed water discharge valve (44 in Fig. 14) to be described later. As described above, the condensed water discharge valve 44 is a valve that maintains a blocked state when electricity is supplied from the outside, so that the condensed water discharge button 76 receives electricity transmitted to the condensed water discharge valve 44 when pressed. Shut off valve. By pressing the condensate discharge button 76, the circuit configuration to cut off the electricity delivered to the condensate discharge valve 44 can also be implemented by those skilled in the art as a basic circuit knowledge.

As described above, when the oxygen generator 10 is applied to a vehicle, the control panel 12 is installed around the driver's seat to allow the driver to conveniently operate. In addition, when the oxygen generator 10 is used indoors as shown in FIGS. 25A and 25B, the position of the control panel 12 can be freely selected as long as the oxygen generator can be controlled.

The oxygen supply line 24 is a passage for supplying the oxygen produced in the main body 15a to a place where it is needed. In this embodiment, the oxygen supply line 24 is provided near the ceiling of the driver's seat inside the vehicle V. The oxygen supply line 24 is connected to the oxygen discharge pipe 18 by the connector 92 can be separated from the oxygen discharge pipe 18 as necessary.

The oxygen supply line 24 extends through the ceiling surface of the room to the inside of the grill 26 whose end is provided on the front of the driver's seat. Therefore, oxygen generated from the main body 15a is supplied to the room through the grill 26. At this time, the air conditioner or heater can also be operated simultaneously with the oxygen generator.

In addition, a second condensate trap 121 is further installed in the oxygen supply line 24. The second condensate trap 121 is installed in preparation for condensed water from the oxygen passing through the oxygen supply line 24. The basic function of the second condensate trap 121 is the same as a conventional condensate trap.

The second condensate trap 121 has a sealed case 121a through which condensate is collected, and the oxygen supply line 24 is inserted into and fixed to the inside of the sealed case 121a in a state where an arbitrary portion is cut. The sealing case 121a is sealed by the sealing cap 121b.

As a result, the oxygen flowing in the oxygen supply line 24 flows through the sealed case 121a. If condensed water is generated at this time, the generated condensed water accumulates inside the sealed case 121a by gravity.

The second condensate trap 121 may be installed at any place desired by the user, and preferably, the second condensate trap 121 may be installed at the lower side of the steering wheel.

8 to 13 are diagrams for explaining the internal structure of the main body of the oxygen generating apparatus according to the first and second embodiments of the present invention showing an example in which the inverter 80 is installed in the main body described with reference to FIG. It was. Except for the inverter 80 from the drawing has a configuration of the main body described in FIG.

Referring to FIG. 8, the main body 15c of the oxygen generator 10 according to the second embodiment includes a case 11 having an air inlet pipe 16 and an oxygen discharge pipe 18 to provide an inner space, It is installed inside the case 11, the first pump 36 to suck the outside air through the air inlet pipe 16, and is connected to the first pump 36, the first pump 36 Oxygen separator 38, which separates the oxygen in the air and passes gas other than oxygen through the nitrogen exhaust pipe 20, is connected to the oxygen separator 38, and the oxygen separator 38 The second pump 40 for moving the oxygen separated by the) and the condensed water connected to the second pump 40 and generated during the generation of oxygen from the oxygen having a condensate discharge valve 44 in the lower portion A condensate trap 42 and a controller 14 for controlling the pumps 36 and 40 and the condensate trap 42.

The first pump 36 and the second pump 40 may apply a well-known centrifugal pump.

The controller 14 receives AC electricity through the inverter 80 or the connector 81a to control the operation of the pumps 36 and 40 and the condensate discharge valve 44. In addition, when the inverter 80 is not built in, as shown in FIG. 2, AC electricity is directly supplied from the connector 81a.

On the other hand, the oxygen ejected from the oxygen separator 38 generates condensed water by the change of temperature and pressure according to the ejection.
