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...

Embodiment approach 2

[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 an air purification device for vehicles, and its object is to provide a DOR (Direct? Ozone? Reduction: direct reduction of ozone) system capable of suppressing the reduction of ozone purification performance due to water adhesion and recovering Ozone purification performance. In the present invention, activated carbon as an ozone purifier is applied to the respective corners of the radiators (14, 16) and the condenser (18). As shown in Figure 5, when water adheres to the fine pores of activated carbon and its surroundings, it is difficult for ozone to enter the mesopores and micropores. In addition, even if ozone enters, it is difficult to donate electrons to ozone from activated carbon. Thus, during water attachment, the ozone purification performance of the activated carbon will be reduced. Therefore, when the amount of moisture adhered to the activated carbon becomes more than a predetermined amount, the moisture release control is performed by forcibly increasing the temperature of the activated carbon to release the moisture.

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 ...
