Abstract

The vehicular humidified cool wind system includes a blower, atomizing means, a water tank and an air passage which are integrated, and is mounted on the ceiling above the driver to blow out a humidified wind downward. The air passage is divided into a humidified wind passage to be fed with atomized water and an ordinary wind to be fed with no atomized water. The air outlet has a double duct structure, an internal cylinder and external cylinder, in which the humidified wind having passed through the humidified wind passage is blown out of an internal cylinder whereas the ordinary wind having passed through the ordinary wind passage is blown out of an external cylinder around the internal cylinder. The humidified wind is prevented from diffusing while being surrounded by the ordinary wind, so that it efficiently reaches the driver to give him a cool feeling.

Claims

1. A humidified cool wind system for vehicles, comprising:

an air passage arranged over a driver for passing air therethrough, said air passage having a downwardly directed air outlet for blowing out the air from above the driver toward the driver;

a blower for producing an air flow from said air outlet toward the driver; and

atomizing means for atomizing water to produce the atomized water in said air passage,

wherein said air passage includes a humidified wind passage to be fed with the air and the atomized water atomized by said atomizing means and an ordinary wind passage to be fed with an ordinary wind containing no atomized water, said air outlet includes an internal cylinder for blowing out the humidified wind passing through said humidified wind passage and an external cylinder for blowing out the ordinary wind passing through said ordinary wind passage from around said internal cylinder.

2. A humidified cool wind system for vehicles according to claim 1,

wherein said air outlet is disposed in a position before and above the face of the driver.

3. A humidified cool wind system for vehicles according to claim 1,

wherein said air outlet is disposed in a position before and above, and at the lefthand and righthand sides of the face of the driver.

4. A humidified cool wind system for vehicles according to claim 1, further comprising evaporating members arranged around said internal cylinder, having communication with said internal cylinder for absorbing condensed water in said internal cylinder to evaporate the absorbed condensed water with the ordinary wind flowing in said external cylinder.

5. A humidified cool wind system for vehicles according to claim 1,

wherein said internal cylinder is made of a flexible tube which is deformable in a normal direction with respect to the flow direction of the humidified wind, said external cylinder is made of a flexible duct which is deformable in a normal direction with respect to the flow direction of the ordinary wind and holds its deformed state, said external cylinder has a holding portion for holding said internal cylinder at an exit end, said holding portion is movable along the flow direction of the air with respect to said internal cylinder.

6. A humidified cool wind system for vehicles according to claim 1,

wherein said humidified wind passage includes an atomizing chamber for guiding the humidified wind in a horizontal direction and a downward guide passage for guiding the humidified wind from said atomizing chamber into said internal cylinder disposed downward, and

wherein around an opening for guiding the humidified wind from said atomizing chamber to said downward guide passage, a weir which is erected from the bottom portion of said atomizing chamber for preventing the condensed water condensed in said atomizing chamber from being guided into said downward guide passage.

7. A vehicular humidified cool wind system according to claim 1,

wherein said atomizing means includes a water supply tank for supplying water,

a humidifying water reservoir to be supplied with the water from said water supply tank,

an ultrasonic oscillator for producing ultrasonic waves to focus in the vicinity of the liquid level of said humidifying water reservoir, and

a turn water passage including a backward water passage for guiding the water flown out of said water supply tank in a opposite direction of said humidifying water reservoir, and a forward water passage for guiding the water in a direction of said humidifying water reservoir which is guided once in a opposite direction of said humidifying water reservoir.

8. A vehicular humidified cool wind system according to claim 1,

wherein said air outlet is arranged at the back of the head of the driver.

9. A humidified cool wind system for vehicles, comprising:

a casing disposed over a driver;

a blower disposed in said casing for generating a flow of air;

atomizing means disposed in said casing for generating atomized water;

a humidified wind passage disposed downstream of said casing for leading the air and the atomized water atomized by said atomizing means;

an ordinary wind passage disposed downstream of said casing for leading the air containing no atomized water,

an internal cylinder connected to said humidified wind passage for blowing out the air and the atomized water from said humidified wind passage simultaneously;

an external cylinder for blowing out the air from said ordinary wind passage, said external cylinder connected to said ordinary wind passage and disposed around said internal cylinder to cover an outer periphery of said internal cylinder so that the air including the atomized water reaches the driver without dispersing with being surrounded by the air from said ordinary wind passage.

10. A humidified cool wind system for vehicles according to claim 9, further comprising evaporating members is disposed in said external cylinder, said evaporating members having a leading means for leading condensed water from said internal cylinder to evaporate the absorbed condensed water with the air flowing in said external cylinder.
