Description

Oxygen generating device for dual application either in vehicles or indoor}

The present invention relates to a vehicle and an indoor combined use oxygen generator.

When operating a heater or an air conditioner with the windows closed in the interior of a vehicle or in an enclosed room, it is well known that air in the enclosed room becomes cloudy for a short time and the concentration of oxygen decreases. This decrease in air pollution and oxygen concentration can easily make passengers and occupants, including drivers, tired and uncomfortable. Therefore, air conditioning systems such as various air cleaners and oxygen generators may be installed in a vehicle or indoors.

The oxygen generator is a mechanical device that separates the oxygen from the sucked air and supplies it to the room. Most of the conventional oxygen generators are oxygen generators employing PSA (Pressure Swing Adsorption). The PSA method obtains oxygen by alternately passing air through two columns filled with zeolites, and its configuration is complicated and heavy, so it is difficult to install and can be used fixedly in one place. It was difficult to use when the necessary place was changed.

In addition, it is not easy to understand the oxygen concentration in the room, so it is not easy to know whether the user is currently in an oxygen environment or in an optimal oxygen environment, and thus it is insufficient to give the user a physical and psychological comfort.

In addition, the PSA oxygen generator must backwash the zeolite that adsorbs oxygen, so the oxygen production amount is not large and the oxygen concentration is not constant compared to the size of the device.

The present invention has been created to solve the above problems, the structure and operation mechanism is simple, the concentration of oxygen generated is constant and the device can be compactly embedded in the case can be used as a mobile, and also visually present through the display By allowing the user to recognize the oxygen concentration, the user can feel comfortable and at the same time, the condensate generated during the oxygen generation process can be discharged under the control of the controller. It is an object of the present invention to provide an oxygen generator having a vehicle and an indoor combined oxygen generator that is easy to manage when configured to automatically exit.

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 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.

Referring to FIG. 4A, the oxygen generator 10 according to the first embodiment of the present invention is installed in the trunk of the vehicle V and supplies the oxygen to the room through the oxygen supply line 24. And a control panel 12 connected to the main body 15a by wire or wirelessly and controlling the main body 15, power supply means for supplying electricity of the cigar jack port 82 to the main body 15a, and It is configured to include an oxygen concentration sensor 78 for detecting the oxygen concentration.

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 indoor location.

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.

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.

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.

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.
