Description

  The present invention relates to a vehicle oxygen enrichment device that supplies oxygen enriched air 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.

  In general, as the oxygen enrichment apparatus, a device using an oxygen enrichment membrane in which a silicone organic membrane is formed on the surface of a porous material support membrane layer is well known. This oxygen enrichment device using an oxygen enriched film forms a partial pressure difference between both interface portions of the oxygen enriched film, so that oxygen permeates and diffuses into and out of the silicone-based organic film, and oxygen is enriched on the negative pressure side. It is the structure from which chemical air is separated.

  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 also a type in which the secondary side of the oxygen-enriched membrane 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 passenger compartment is limited.

Furthermore, as an oxygen enrichment device, a device using a pressure swing system utilizing a zeolite adsorption characteristic by providing a flow path in an adsorption section filled with two zeolites is also well known.

  However, the oxygen enrichment apparatus using the oxygen enriched film has the following problems. That is, the separation ratio by the oxygen-enriched membrane is larger for water vapor / nitrogen and carbon dioxide / nitrogen than for oxygen / nitrogen. Therefore, since the water vapor in the atmosphere is enriched in the same manner as the target oxygen, there is a problem that the flow path for transporting the oxygen-enriched air is condensed or frozen. In addition, in order to form a partial pressure difference between the two interface portions of the oxygen-enriched film, there is a problem that noise is generated when the pump is driven because a pressure pump or a pressure reduction pump is used. In addition, since the oxygen concentration of the oxygen-enriched air produced by the oxygen-enriched film is about 30%, the vehicle has a reduced oxygen concentration or an oxygen-enriched vehicle when a passenger is in the passenger compartment. There is a problem that an indoor air environment cannot be provided. Furthermore, there is also a problem that the gas permeation amount to the oxygen-enriched film is reduced as the atmospheric temperature is lowered.

Moreover, the oxygen enrichment apparatus using the above zeolite has the following problems. That is, when natural air is adsorbed onto zeolite, there is a problem that oxygen adsorption characteristics are reduced due to moisture adsorption in the air. Moreover, when the pollutant odor in air | atmosphere adsorb | sucks to a zeolite, there exists a problem that a pollutant odor is desorbed and it sends out with oxygen enriched air.

  Therefore, the present invention solves the above problems, aims to prevent occupant fatigue recovery, drowsiness, prevention of motion sickness, etc., and in order to form a comfortable riding environment, only target oxygen is selectively separated from nitrogen, An object of the present invention is to provide a vehicular oxygen enrichment device capable of supplying oxygen-enriched air having a high oxygen concentration to a passenger.

  In order to solve the above problems, a vehicle oxygen enricher of the present invention includes at least a solid electrolyte oxygen pump, an air supply path on the primary side of the solid electrolyte oxygen pump, and a secondary side of the solid electrolyte oxygen pump. In the vehicle oxygen enrichment apparatus in which an oxygen supply path is provided, oxygen separated by the solid electrolyte oxygen pump is sent out to an interior of a vehicle compartment from an oxygen outlet provided in the oxygen supply path. To do.

  In this way, oxygen selectively separated by the solid oxide oxygen pump is sent into the passenger compartment, so that even if an occupant is in the passenger compartment, the oxygen concentration does not decrease or is enriched with oxygen. A car interior air environment can be provided. Further, oxygen selectively separated by the solid electrolyte oxygen pump is further generated as oxygen-enriched air whose oxygen concentration is adjusted by introduction of the atmosphere, and this can be inhaled by the occupant.

  As is apparent from the above embodiment, according to the oxygen enrichment device for a vehicle of the present invention, oxygen is selectively separated by the solid electrolyte oxygen pump and delivered to the vehicle interior. Even if the vehicle is on board, the oxygen concentration does not decrease or the vehicle interior air environment enriched with oxygen can be provided.
