Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ventilation system for a vehicle, and more particularly to a vehicle air purification system in which a bypass communication port is provided in a communication port constituting the vehicle air cleaning device.

[0002]

[Prior Art]

 Conventionally, this type of device is a vehicle air conditioner having an air cleaning function, as described in Japanese Utility Model Laid-Open No. 62-203706, and an exhaust structure to the outside of the vehicle body has been discussed. This conventional example has an exhaust port that opens in the exhaust mode, and exhausts from this exhaust port through an air cleaning device.

[0003]

[Problems to be solved by the device]

 The prior art does not consider the life of the air purifier. That is, in addition to when the air purifier is operating under normal conditions, the air inside the cabin exhausted to the outside of the passenger compartment also passes through the air purifier during forced ventilation. However, there is a problem that the life of the air purifier is shortened due to the increase in

An object of the present invention is to ensure the life of an air purifier at the same level as when a normal air purifier operates while maintaining low cost and space saving.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a bypass passage C for connecting the air intake port 2 and the air outlet port 5 is provided, and a door 8 for switching between the bypass communication port C and the ventilation passage A is used during normal operation of the air cleaning device. Therefore, when switching to forced ventilation, the air inside the vehicle is operated so as to bypass the air purifier 3.

[0006]

[Action]

 By providing a ventilation path B between the passenger compartment and the trunk and connecting the downstream side of the blower 4 to the ventilation path B, the blower 4 of the air purifying device can be used as a ventilation blower. At this time, the communication port 12 that connects the air intake port 2 and the air outlet port 5 and the door 8 that switches the ventilation path are operated to the communication port opening side. As a result, the passenger compartment air that is exhausted in the trunk during forced ventilation is exhausted from the air outlet port 5 through the bypass communication port C, and thus does not pass through the air purifier 3. It is possible to secure the same service life as when the normal air cleaning device is operating, without increasing the air conditioner.

In the present embodiment, an air purifier 3 is provided on the upper part of the device body 1 so as to face directly below the air suction port 2, and a blower 4 is arranged below the device body 1 directly below the air cleaner 3. Be done. Further, an internal air circulation purification system air passage A and a natural ventilation system air passage D are formed in the upper part of the device body 1 so as to be adjacent to the air purifier 3, and a blower is installed in the lower part of the device body 1. 4, the forced ventilation system air passage B is formed.

That is, in the inside air circulation purification system air passage A, an air purifier 3 and a blower 4 are arranged in a two-tiered structure immediately below the air suction port 2, and up to the air passage branch portion 11 downstream of this air blower. Passes through the lower part of the device body 1 and leads to the air outlet 5 arranged at the upper part of the device body 1. On the other hand, the forced ventilation system air passage B is passed by the air outlet 5 of the inside air circulation purification system air passage A through the communication port 12 formed in the passage wall of the branch portion and the blower 4 at the lower part of the device body 1. Then, the air exhaust port 6 that joins the natural ventilation system air passage D through the communication port 13 formed in the passage wall of the branch portion 11 and communicates with the inside of the trunk is the forced ventilation system air passage B and the natural ventilation system wind. It becomes a common exhaust port with the passage D.
