Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vehicle negative ion generator.
[0002]
[Prior art]
Conventionally, a negative ion generator for emitting negative ions for a vehicle occupant is known. As a method of disposing the negative ion generators in the vehicle interior, for example, there is an example in which four negative ion generators are respectively disposed at positions above the respective seats on the ceiling. However, in this case, since the number of negative ion generators is large and the cost is high, it is desired that one negative ion generator effectively distributes negative ions in the vehicle interior.
[0003]
Therefore, a method of disposing a negative ion generator in the center of the ceiling has been proposed. Since it is located at the center of the ceiling, negative ions are expected to be distributed both on the front side and the rear side of the vehicle.However, when the air conditioner operates, the negative ions are generated by the air-conditioned wind flowing to the rear side of the vehicle. There is a tendency that the negative ions are not sufficiently distributed to the occupants in front of the vehicle, and the negative ions cannot be effectively distributed to each occupant.
[0004]
[Problems to be solved by the invention]
In view of the above problems, an object of the present invention is to provide a vehicle negative ion generator that effectively distributes negative ions to each occupant.
[0005]
[Means for Solving the Problems]
According to the vehicle negative ion generator according to the first aspect of the present invention, in the vehicle negative ion generator for generating negative ions, the negative ion generator is disposed near the ceiling in front of the vehicle. As a result, a part of the negative ions generated by the negative ion generator descends due to its own weight and distributes in front of the vehicle, and the other part of the negative ions is generated by the inertial force and air-conditioning wind generated during the operation of the vehicle. It is distributed rearward, that is, distributed to the front and rear seats.
[0006]
According to the vehicle negative ion generator according to the second aspect, the negative ion generator is incorporated in a map lamp module mounted on a ceiling in front of the vehicle. Thereby, there is a further advantage that the space for disposing the negative ion generator can be eliminated and the space in the vehicle interior can be widened.
[0007]
According to the vehicle negative ion generator of the third aspect, the negative ion generator is disposed behind the sun visor attached to the ceiling in front of the vehicle. Thereby, the position where the negative ion generator is arranged is thereby further specified.
[0008]
According to the vehicle negative ion generator according to the fourth aspect, the negative ion generator is incorporated in a mirror structure mounted on a ceiling portion in front of the vehicle. Thereby, there is a further advantage that the space for disposing the negative ion generator can be eliminated and the space in the vehicle interior can be widened.
[0009]
According to the vehicle negative ion generator according to the fifth aspect, the negative ion generator is incorporated in an air outlet of a vehicle air conditioner provided in front of the vehicle. As a result, the negative ions generated by the negative ion generator flow from the front of the vehicle to the rear together with the air-conditioning air, and are distributed to the front seat and the rear seat. Further, there is a further advantage that the space for disposing the negative ion generator can be eliminated and the space in the vehicle interior can be widened.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, the negative ion generator of the first embodiment will be described with reference to FIGS. FIG. 1 is a perspective view of a map lamp module disposed on a ceiling portion in front of a vehicle, and FIG. 2 is a sectional view of the map lamp module. As shown in FIG. 1, a map lamp module unit 10 having a lamp 12 for illuminating a driver's seat and a passenger seat is arranged on a ceiling in front of the vehicle.
[0011]
As shown in FIG. 2, a negative ion generator 11 is incorporated inside the map lamp module unit 10. On the surface of the map lamp module unit 10, an outlet 11a for discharging negative ions and a switch 11b for controlling the operation of the negative ion generator 11 are provided. Alternatively, in addition to the map lamp 12 and the negative ion generator 11, a storage case unit 13 for storing small items such as glasses may be optionally incorporated in the map lamp module unit 10. . Thereby, the space for disposing the negative ion generator 11 can be eliminated, and the space in the vehicle interior can be widened.
[0012]
Next, the operation of the negative ion generator 11 will be described. The negative ions generated by the negative ion generator 11 are discharged into the passenger compartment through the air outlet 11a, and a part of the negative ions descends by its own weight and distributes in front of the vehicle, while other negative ions are distributed to the front of the vehicle. The portion flows rearward due to inertial force generated at the rear of the vehicle when the vehicle is accelerating, or is selectively flown by conditioned air when the air conditioner is operated, and is distributed behind the vehicle. In this way, negative ions can be distributed both in front of and behind the vehicle, that is, in each occupant.
[0013]
Next, a second embodiment will be described with reference to FIGS. FIG. 3 is a sectional view showing the arrangement of the negative ion generator of the second embodiment. In the second embodiment, the vehicle negative ion generator 21 is incorporated in a ceiling portion (region A surrounded by a dotted line in FIG. 1) behind the sun visor 20. Thereby, the space for disposing the negative ion generator 11 can be eliminated, and the space in the vehicle interior can be widened. At the time of operation, the negative ions coming out of the outlet 21a of the negative ion generator 21 can be distributed to each occupant, as in the first embodiment.
[0014]
Next, a third embodiment will be described with reference to FIG. FIG. 4A is a sectional view showing the arrangement of the negative ion generator of the third embodiment, and FIG. 4B is a front view of a mirror structure. In the third embodiment, the vehicle negative ion generator is installed inside the mirror structure 30 behind the mirror surface 32. On the surface of the mirror structure 30, an outlet 31a for emitting negative ions and a switch 31b for controlling the operation of the negative ion generator 11 are provided. Thereby, the space for disposing the negative ion generator can be eliminated, and the space in the vehicle cabin can be widened. At the time of operation, negative ions coming out of the outlet 31a of the negative ion generator 31 can be distributed to each occupant, as in the first embodiment.
[0015]
Finally, a fourth embodiment will be described. In the fourth embodiment, the vehicle negative ion generator is incorporated in the center outlet of an air conditioner provided in front of the vehicle. Thereby, the space for disposing the negative ion generator can be eliminated, and the space in the vehicle cabin can be widened. At the time of operation, negative ions generated by the negative ion generator are discharged into the passenger compartment through the air outlet of the air conditioner, and the negative ions are flown by the conditioned air and flow from the front to the rear of the vehicle, and the front seat and the rear Distributed in side seats.
