Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air cleaner that sucks dirty air inside a vehicle interior and blows out clean air.

The air inside the vehicle is polluted due to cigarette smoke, dust, etc. Therefore, air purifiers have been conventionally used to purify the air inside the vehicle. By the way, the function of this conventional air purifier is to simply suck in the air inside the car and clean it, so if the temperature inside the car is at an appropriate temperature, there is no problem, but if the temperature inside the car is not the right temperature, there is no problem. For example, when the temperature inside the vehicle is low, cold air blows out, and when the temperature inside the vehicle is high, hot air blows out.

Furthermore, even if the air inside the vehicle can be cleaned by exchanging the air inside the vehicle with outside air (ventilation), conventional air purifiers do not have a ventilation function, so the air inside the vehicle There was no choice but to perform a cleaning operation by circulating the water. Normal ventilation in cars is carried out by a ventilator, but if the air inside the car is severely contaminated, this function alone is insufficient.
Windows will have to be opened and closed manually. but,
When opening and closing the windows, the temperature inside the vehicle rapidly approaches the temperature of the outside air, so people often hesitate to ventilate the vehicle.

The present invention has been made in view of these problems, and its purpose is to provide an air purifier that can quickly purify the air while bringing the temperature in the vehicle interior close to the appropriate temperature, that is, the temperature of the blown air can be adjusted. Our goal is to create the best possible air purifier.

The present invention achieves this objective in an air purifier that sucks dirty air inside a vehicle interior and blows out clean air.The present invention has a first air purification mode that sucks air inside the vehicle interior, cleans it, and blows it out again into the interior of the vehicle. other,
A second air purification mode is also selected, in which the air inside the vehicle is discharged to the outside of the vehicle, and the air outside the vehicle is taken in and blown into the interior of the vehicle. When the first air cleaning mode is selected, an air passage for guiding heated air or cooling air is formed at the other end of the heat pipe, and when the second air cleaning mode is selected, When selecting,
The heat pipe is characterized in that an air passageway is formed at the other end of the heat pipe to guide the air inside the vehicle interior and release it outside the vehicle interior.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 indicates a suction port for sucking dirty air inside the vehicle interior, and reference numeral 2 indicates an outlet for blowing clean air into the vehicle interior. Above suction port 1 and outlet 2
are connected by main passages 3 to 5,
Various parts that make up the air purifier are arranged inside. First, 6 in the main passage 3 is a mesh filter,
It is used to catch large debris. After the mesh filter 6, there is a dust collector 7 that first charges fine dirt and dust and then captures it using static electricity, an activated carbon filter 8 that removes odors, and an activated carbon filter 8 that sterilizes and sterilizes the air that has passed through the activated carbon filter. An ultraviolet lamp 9 for disinfection is provided. Further, in the main passage 5, a Sirotskov fan 10 for sending clean air to the outlet 2 side, and an anion generator 11 that adds anions to the air sent out from the Sirotskov fan and sends it to the outlet 2 are disposed. ing.

Further, 12 is a heat pipe, one end of which is 12a.
are exposed in the main passage 5, and the blown air is heated or cooled by the fins. The other end side 12b of the heat pipe 12 is exposed inside the chamber 13. By the action of the exhaust fan 14, the air inside the vehicle compartment flows into the chamber 13 through the auxiliary passage 15, or the cooled/heated air from the air conditioner/heater flows through the width passage 16. It's summery. 17 and 18 are switching valves, switching valve 1
Reference numeral 7 is for selecting either the air in the vehicle interior or the air from the air conditioner, and the switching valve 18 is for selecting either the air from the air conditioner or the air from the heater. Further, 19 is a sub passage for introducing outside air into the main passage 5. The switching valve 20 allows outside air to flow into the main passage 5 via the sub passage 19, or air in the main passage 4 to flow into the main passage 5 through the sub passage 19.
It depends on whether it will flow into the

Next, the operation of the air purifier having the above configuration will be explained.

First, during the same operation as the conventional device, the switching valves 17 and 20 are in the positions shown by the solid lines, and only the sirotsky fan 10 is driven. As a result, the air inside the vehicle enters the main passage 3, is collected by a mesh filter 6 and a dust collector 7, deodorized by an activated carbon filter 8, and then disinfected by an ultraviolet lamp 9. After that, enter the main passage 5 via the main passage 4,
Anions are added by the anion generator 11, and the air is returned to the vehicle interior as clean air through the outlet 2.
returned via.

In addition to this cleaning operation, the air cleaner of the present invention can control the temperature of the blown air. That is,
The switching valve 18 is placed in the position shown by the solid line, and the heated air from the heater is guided into the room 13 by the exhaust fan 14.
By heating the other end 12b of the heat pipe 12, the temperature of the one end 12a can be increased and the blown air flowing there can be heated. Furthermore, by placing the switching valve 18 in the position shown by the broken line and guiding cooling air from the air conditioner into the room 13, the temperature at one end 12a of the heat pipe 12 can be lowered and the air flowing therethrough can be cooled.
Therefore, the temperature of the blown air can be changed by switching the air introduced into the room 13, so that the air inside the vehicle can be purified while bringing the temperature inside the vehicle close to an appropriate temperature.

The above operation was to circulate and purify the air inside the vehicle interior, but the air purifier of the present invention can also purify the vehicle interior by introducing outside air into the vehicle interior without substantially changing the temperature inside the vehicle interior. can. That is, the switching valves 17 and 20 are moved to the positions shown by broken lines, and the Sirotskov fan 10 and the exhaust fan 1 are
4, the outside air flows into the sub passage 19 and the main passage 5.
The air is blown out from the air outlet 2 into the vehicle interior. At this time, the air inside the vehicle is drawn from the suction port 1 to the main passage 3.
flows into the chamber 13 via the sub-passage 15,
It is then released outside the vehicle. Therefore, the temperature of the one end side 12a of the heat pipe 12 is heated or cooled so that the outside air passing there approaches the temperature inside the vehicle interior. Therefore, the temperature of the blown air approaches the temperature inside the vehicle interior, and the temperature inside the vehicle hardly changes.

In this case, it is also possible to introduce outside air without exhausting the air inside the vehicle interior. This can be done by moving the switching valve 17 to the position shown by the solid line.
Further, at this time, in order to heat or cool the blown air, heated air or cooled air may be introduced into the chamber 13, as in the case described above.

In the above description, the arrangement of each part for air purification is not limited to that of the above embodiment. For example, all the parts may be arranged in the main passage 5 as shown in FIG. It is also possible to add or delete parts themselves, or to replace them with other parts.

As explained above, according to the present invention, it is possible to realize an air purifier that can quickly clean the air while bringing the temperature inside the vehicle compartment close to an appropriate temperature.
