Embodiment approach 1

[0060] [Structure of air purification device for vehicle]

[0061] First, refer to Figure 1 to Figure 6 , Embodiment 1 of the present invention will be described. figure 1 It is a figure which shows the structure of the vehicle equipped with the air purification apparatus of this Embodiment 1. figure 1 The illustrated vehicle 10 is a hybrid vehicle equipped with an internal combustion engine 12 and an electric motor (described later) as power plants. HC and NOx are contained in the exhaust gas discharged from the internal combustion engine 12 . Ozone is produced by a photochemical reaction using HC and NOx as reactants. Therefore, by installing an air purification device on the vehicle 10 to purify the ozone in the atmosphere while the vehicle 10 is running, the impact of the vehicle 10 on the environment can be reduced.

[0062] In the vehicle 10 , a radiator 14 for cooling cooling water circulating in the internal combustion engine 12 is arranged in front of the interna...

[0113] [Structure of air purification device for vehicle]

[0114] Second, refer to Figure 9 to Figure 11 , Embodiment 2 of the present invention will be described. first, Figure 9 It is a figure which shows the structure of the vehicle equipped with the air purification apparatus of this embodiment. Figure 9 Vehicle 70 shown with figure 1The structures of the vehicles 10 are basically common, in that a slit-shaped heat insulator 64 is provided between the exhaust manifold 62 of the internal combustion engine 12 and the radiator fan 20, and in the radiator 14 and the radiator 16. Between this point is provided a dew point sensor (hygrometer) 66, with figure 1 The structure of the vehicle 10 is different. In addition, a catalyst (not shown in the figure) for purifying exhaust gas is provided on the exhaust manifold 62 .

[0115] In Embodiment 1 described above, the water pump 28, the electric thermostat 30, and the like are driven to perform moisture desorption control...

Abstract

The present invention relates to a vehicle atmosphere purifying apparatus aiming to provide a direct ozone reduction (DOR) system such that a decrease in ozone purifying performance due to water attachment can be suppressed and ozone purifying performance can be recovered. According to the present invention, a core portion of each of radiators (14, 16) and a capacitor (18) is coated with activated charcoal as an ozone purifier. As shown in FIG. 5, when water is attached to activated charcoal pores or their surrounding areas, it becomes difficult for ozone to enter mesopores or micropores. Even if ozone could enter, it becomes difficult for electron donation to occur from the activated charcoal to ozone. Thus, the ozone purifying performance of the activated charcoal is decreased as long as there is the attached water. Thus, when the amount of water attached to the activated charcoal is not less than a predetermined amount, a water elimination control is performed to eliminate water by compulsorily heating the activated charcoal.

Description

technical field [0001] The present invention relates to an air purification device for a vehicle, and relates to an air purification device for a vehicle capable of purifying ozone in the atmosphere. Background technique [0002] In the past, in air purification using activated carbon, it was known that the adsorption performance was lowered by long-term use, and various measures for regeneration were taken for this reason. For example, in Patent Document 1, an air conditioner in a vehicle is disclosed, which is equipped with an activated carbon filter that absorbs odor components or harmful components in the air supplied to the vehicle, and the filter A heating device in physical contact, and a blower to generate the air flow for cleaning. In this in-vehicle air conditioner, the heating device is operated while the flow of cleaning air generated by the operation of the blower passes through the filter. Thereby, since the activated carbon and air in the said filter can be ...
