Description

  The present invention relates to a vehicle oxygen enrichment apparatus that efficiently supplies oxygen enriched air having a high oxygen concentration to a passenger.

  In general, vehicles, especially automobiles, provide a comfortable riding environment for passengers regardless of the climate (especially temperature) and driving conditions, and prevent drivers from getting cloudy windows and frost, Air conditioners are installed to ensure safe and comfortable driving. Furthermore, in recent years, diversification of functions has progressed, and in addition to conventional air conditioning functions such as heating, cooling, humidification, and dehumidification, an oxygen enrichment function for supplying oxygen-enriched air into the passenger compartment has been proposed. ing.

  For example, there is one that supplies pressurized air to the primary side of the oxygen-enriched membrane to generate oxygen-enriched air and supplies it to the passenger compartment (see, for example, Patent Document 1). The oxygen-enriched device sends air pressurized to about one atmosphere by a pressure pump to the primary side of the oxygen-enriched membrane, supplies the generated oxygen-enriched air to the vehicle interior, and nitrogen-enriched air is outside the vehicle interior. Has been released.

In addition, there is a type in which the secondary side of the oxygen-enriched film is sucked under reduced pressure to generate oxygen-enriched air, which is supplied into the passenger compartment and the supply amount is limited (see, for example, Patent Document 2). The oxygen enrichment apparatus sucks the secondary side of the oxygen enriched film by reducing the pressure with a decompression pump, supplies the generated oxygen enriched air into the vehicle compartment, and sets a regulation value for the suction negative pressure of the decompression pump. The oxygen-enriched air supply amount to the vehicle interior is limited.

  However, in the case where oxygen-enriched air is generated by supplying pressurized air to the primary side of the oxygen-enriched membrane, there are the following problems. That is, when the primary side air of the oxygen-enriched membrane is pressurized, the partial pressure difference needs to be increased as compared with the case where the secondary side air of the oxygen-enriched membrane is sucked under reduced pressure. Furthermore, the pressure pump is more expensive than the pressure reduction pump.

  In addition, when the secondary side of the oxygen-enriched membrane is sucked under reduced pressure to generate oxygen-enriched air that is supplied into the passenger compartment and its supply rate is limited, there are the following problems. It was. That is, since the oxygen-enriched air is not sent directly into the passenger compartment in a configuration that is easily inhaled by the passenger, the oxygen concentration is reduced by mixing with the passenger compartment air in the route until the oxygen-enriched air is inhaled by the passenger. End up. Therefore, there is a problem that even if oxygen-enriched air having a high oxygen concentration is supplied into the passenger compartment, the passenger cannot efficiently inhale the oxygen-enriched air having a high oxygen concentration.

  Therefore, the present invention solves the above-mentioned problems and efficiently supplies oxygen-enriched air having a high oxygen concentration to the occupant in order to form a comfortable riding environment in order to prevent occupant fatigue, drowsiness, prevention of motion sickness, etc. It is an object of the present invention to provide an oxygen enrichment device for a vehicle that can be used.

In addition, the outside air introduced from the outside air intake port is constantly supplied to the primary side of the oxygen-enriched membrane, and an air flow is generated in the air supply path along with the rotation of the blower fan, thereby scavenging the nitrogen-enriched air that remains. Thus, oxygen-enriched air having a high oxygen concentration can be continuously generated. In addition, the condensed water adhering to the oxygen-enriched air supply channel by the high-humidity oxygen-enriched air is dried by sending a large amount of low-humidity air to dry, reducing the noise caused by the condensed water and device reliability. Can be improved.

Therefore, noise due to condensed water can be reduced, and flow path blockage due to condensed water freezing and backflow of condensed water to the decompression pump 2 can be prevented.

  In this manner, by sending the atmosphere 21 to the oxygen-enriched air supply path 6, noise reduction and equipment reliability can be improved.
