An actuator 20 is engaged with the exhaust door 17 via a link 19, and the operation of the actuator 20 causes the exhaust door 17 to open and close. The packing 21 is attached to the peripheral edge of the exhaust door 17 and is provided to increase the airtightness between the peripheral edge of the exhaust door 17 and the inner wall of the case 5. Reference numeral 22 denotes a battery dedicated to the fan motor for driving the fan motor 12, and the battery 22 is preferably, for example, a Ni-Cd battery of AA × 4 type or a nickel-metal hydride battery.

A circuit board 23 controls the rotation of the fan motor 12 and controls the actuator 20.
The circuit board 23 is fixed to the inside of the circuit board cover 24 by mounting screws 25, and the circuit board cover 24 to which the circuit board 23 is mounted is mounted to the outside of the other case component 6B by mounting screws 26. .

Numeral 27 denotes a lid which is put on the battery storage chamber 11. The lid 27 is integrally connected to the battery storage chamber 11 through a thin hinge 28.
An air outlet 29 is provided in a part of the battery storage chamber 11, and an air intake 31 is provided in the battery storage chamber 11 in a ventilation path in the case 5 through a duct 30. Have been.

A fan motor 12 to which a sirocco fan 14 is attached, an exhaust door 17 to which a packing 21 is attached, and a filter are provided in a case 5 which is a combination of the one case component 6A and the other case component 6B. By mounting each of the units 15 and further mounting the circuit board cover 24 on which the circuit board 23 is mounted, the link 19, the actuator 20, and the like to the outside of the case 5, an air purifying device for a vehicle is configured. The air purifying device is installed in a semi-enclosed space 4 formed between an interior panel 3 and an exterior panel 2 of a vehicle body, and further includes a battery provided in a case 5 when the vehicle air purifying device is used. A predetermined battery 22 is stored in the storage room 11.

Therefore, when the engine of the vehicle equipped with the vehicle air purifying device 1 is driven (during driving and idling), the vehicle air purifying device 1 is operated by supplying power from the vehicle-mounted battery. If the exhaust port 10 is closed at 17, the interior of the vehicle is cleaned by circulation of the internal air, and if the exhaust port 10 is opened, the air in the vehicle interior is ventilated. During operation of the vehicle air purification device 1 using the vehicle-mounted battery as a power source, rapid charging of the battery contained in the battery storage room 11 is started.

It is desirable that the dedicated battery be used at normal temperature, and the air is conditioned and taken into the battery compartment, so that the battery is cooled at high temperature and heated at low temperature to approach normal temperature to exhibit the performance of the battery. In addition, when the battery is charged, the battery generates heat, and if the heat is left unattended, it becomes a factor of reducing the characteristics and durability of the battery. Therefore, the heat generated during the charging of the battery is suppressed ( cooling)
Is required.
