Description

Air cleaning device for vehicle {AIR CLEANING APPARATUS FOR AUTOMOTIVE VEHICLES}

The present invention relates to a vehicle air cleaning device, and more particularly, to sterilize and deodorize bacteria, fungi and odors inhabiting the air filter to prevent contamination of the air filter and to extend the life of the air filter. It relates to an air cleaning device.

The interior of the car is narrow and airtight, so it is prone to contamination. In particular, indoor air pollution is further increased due to fine dust and various contaminants introduced into the room. And when the air conditioner is operated in rainy or very humid weather, bacteria and fungi that inhabit the surface of the evaporator flow into the room, causing odor and causing various diseases.

In view of this, in recent years, a vehicle air purifier for purifying indoor air of a vehicle has been developed. As an example, there is a loop type air cleaning device installed on the ceiling of a vehicle.

As shown in FIG. 1, the roof type air cleaning device includes a housing 10 installed on an indoor ceiling of a vehicle.

The housing 10 has an air purifying passage 12 therein. The air purifying passage 12 has an inlet 14 for introducing indoor air and an outlet 16 for discharging the introduced air into the room. ).

On the other hand, the air filter 20 is installed in the inlet 14 of the air purification passage 12. The air filter 20 filters the air introduced into the inlet 14. In particular, the harmful substances contained in the air are first removed.

The loop air cleaning device includes a blower 30 that sucks indoor air into the air purification passage 12. The blower 30 includes a fan 32 installed on the air purification passage 12 and a drive motor 34 for rotating the fan 32.

The loop air cleaner includes an ion generator 40 provided on the air purifying passage 12.

The ion generator 40 is a device for forming a large amount of anions and cations, and extends at intervals toward the main body 42, the high voltage generator 43 and the air purifying passage 12 embedded in the main body 42. An anion discharge electrode 44 and a cation discharge electrode 46 are provided.

The ion generator 40 generates anions and cations while being operated by an applied power source, and discharges the generated negative and positive ions on the air purification passage 12.

Therefore, the negative and cationic particles released on the air purification passage 12 can sterilize and deodorize various bacteria and fungi in the air flowing along the air purification passage 12, and thus, into the interior of the vehicle. Increase the cleanliness of the exhaust air to create a comfortable indoor environment of the vehicle.

However, such a conventional air cleaning device has a disadvantage in that a large amount of bacteria and mold inhabit the air filter 20 because the air filter 20 primarily filters the introduced air. Due to the severe odor occurs, the air filter 20 is easily contaminated, there is a problem that the life is shortened.

In particular, when the air cleaning device is turned off, a large amount of odor is generated from the contaminated air filter 20, and there is a problem in that the number of molds and bacteria increases rapidly.

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to provide an air cleaning device for a vehicle that can sterilize and deodorize the bacteria, mold and odor inhabiting the air filter.

Another object of the present invention is to provide a vehicle air cleaning device which can prevent contamination of the air filter and extend the life of the air filter by sterilizing and deodorizing the bacteria, mold, and odors inhabiting the air filter. .

Still another object of the present invention is to provide an air cleaning device for a vehicle that can effectively sterilize and deodorize bacteria, mold, and odors inhabiting the air filter even when the device is turned off.

In order to achieve the above object, the present invention provides a housing having an inlet for introducing air in a vehicle compartment, an air purification passage through which the introduced air is pumped, a discharge port for discharging air from the air purification passage into the vehicle compartment, and the air.

It is characterized by being arranged the same or smaller.

According to the air cleaning device for a vehicle according to the present invention, since the air filter directly sterilizes and deodorizes, there is an effect of efficiently sterilizing and deodorizing bacteria, mold, and odors inhabiting the air filter.

In addition, since the air filter is sterilized and deodorized, there is an effect of preventing contamination of the air filter and extending the life of the air filter.

In addition, since the air filter is sterilized and deodorized when the vehicle is turned on, it is possible to continuously sterilize and deodorize bacteria, molds, and odors in the air filter regardless of the operation of the air cleaner. It works.

In addition, since the air filter is sterilized and deodorized even after the vehicle is turned off, the indoor environment of the vehicle can be comfortably maintained regardless of whether the vehicle is turned on or off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a vehicle air cleaning device according to the present invention will be described in detail with reference to the accompanying drawings.

First, before looking at the features of the vehicle air cleaning device according to the present invention, a brief description of the vehicle air cleaning device with reference to FIGS.

The vehicle air cleaning device includes a housing 10. The housing 10 is installed on the indoor ceiling of the vehicle and has an internal air purification passage 12. The internal air purification passage 12 has an inlet 14 for introducing indoor air and an outlet 16 for discharging the introduced air into the room.

On the other hand, the air filter 20 is installed in the inlet 14 of the air purification passage 12. The air filter 20 filters the air introduced into the inlet 14. In particular, the harmful substances contained in the air are first removed.

The air cleaning apparatus includes a blower 30 that sucks indoor air into the air purification passage 12. The blower 30 is composed of a fan 32 installed on the air purifying passage 12 and a drive motor 34 for rotating the fan 32.

Next, the features of the air cleaning device for a vehicle according to the present invention will be described in detail with reference to FIGS. 2 and 3.

First, the air cleaning apparatus of the present invention includes an ion generator 50 that releases anions and cations on the air purification passage 12.

The ion generator 50 includes a main body 52 and a high voltage applied by the first high voltage generator 54, the second high voltage generator 55, and the first high voltage generator 54 built in the main body 52. The first ion generating unit 60 radiating the pulses downstream of the air filter 20 and the second ion radiating high voltage pulses applied from the second high voltage generating unit 55 upstream of the air filter 20. It consists of the ion generator 70.

The main body 52 is installed inside the housing 10. The first and second high voltage generators 54 and 55 are circuit boards (PCBs) in which a trans, a high voltage diode, a capacitor, etc. are installed. Generate a pulse.

The first ion generating unit 60 is composed of an anion discharge electrode 62 and a cation discharge electrode 64. The anion discharge electrode 62 and the cation discharge electrode 64 are formed of a first high voltage generator 54. In the state electrically connected to the), it is installed at intervals toward the air purification passage (12).

Particularly, the negative ion discharge electrode 62 and the positive ion discharge electrode 64 are provided at intervals toward the air purification passage 12 downstream of the air filter 20, and the first high voltage generator 54 The applied high voltage pulse is radiated downstream of the air filter 20 to generate negative ions and positive ions.

Accordingly, the generated anions and cations can sterilize and deodorize various bacteria and fungi in the air flowing along the air purification passage 12, thereby increasing the cleanliness of the air discharged into the interior of the vehicle. Create a pleasant indoor environment.

The second ion generating unit 70 is composed of an anion discharge electrode 72 and a cation discharge electrode 74, and the anion discharge electrode 72 and the cation discharge electrode 74 are the second high voltage generation unit 55. In the state electrically connected to the), it is installed at intervals toward the air purification passage (12).

In particular, the upstream side air purification passage 12 of the air filter 20 is provided at intervals, and the anion discharge electrode 72 and the cation discharge electrode 74 thus installed are provided in the second high voltage generation unit 55. The applied high voltage pulse is radiated upstream of the air filter 20 to generate negative ions and positive ions.

Therefore, as the generated anions and cations flow into the air filter 20, sterilization and deodorization treatment of various bacteria, molds, and odors inhabiting the air filter 20, and thus, odors generated from the air filter 20. Eliminate, can inhibit the growth of bacteria and fungi, and extends the life of the air filter (20).

On the other hand, since the negative and positive ion particles generated in the negative ion discharge electrode 72 and the positive ion discharge electrode 74 of the second ion generator 70 have a straightness, they are introduced directly into the air filter 20 without the help of blowing air. do. Therefore, it is possible to sterilize and deodorize molds, bacteria, and odors inhabiting the air filter 20 without operating the blower 30.

Here, the negative ion discharge electrode 72 and the cation discharge electrode 74 of the second ion generating unit 70, the distance (L) that the negative, generated cation particles can be introduced into the air filter 20 by the linearity Must be installed within

On the other hand, the anion discharge electrode 72 and the cation discharge electrode 74 of the second ion generating unit 70, compared with the anion discharge electrode 62 and the cation discharge electrode 64 of the first ion generating unit 60. Or to maintain a narrow interval t or equal intervals.

This is because a large amount of ozone is maintained between the anion discharge electrode 72 and the cation discharge electrode 74 by keeping the gap between the anion discharge electrode 72 and the cation discharge electrode 74 of the second ion generating unit 70 narrow. This is to allow (O ₃ ) to occur, which is to allow the ozone having excellent sterilization and deodorization ability to efficiently sterilize and deodorize the air filter 20.

2 and 3 again, the air cleaning apparatus of the present invention includes a controller 80 that controls the ion generator 50.

The controller 80 includes a microprocessor. When the user turns on the air purifier operating switch 10a installed on the outer surface of the housing 10, the controller 80 includes the first and second high voltage generators ( 54, 55).

Accordingly, negative and positive ions may be generated in the first ion generator 60 and the second ion generator 70 connected to the first and second high voltage generators 54 and 55, respectively. The cation can sterilize and deodorize the bacteria, mold and odors of the air filter 20 and the air purification passage 12.

Meanwhile, the controller 80 controls the first and second ion generators 60 and 70, so that more negative and positive ions can be generated in the second ion generator 70. Because, by allowing a greater amount of negative and positive ions can be generated in the second ion generating unit 70, to sterilize and deodorize the air filter 20 with a high degree of contamination.

2 and 3 again, the air cleaning apparatus of the present invention includes a start detecting means 90 for detecting whether the start of the vehicle is turned on or off.

The start detection means 90 is constituted by a start switch of a vehicle. The start switch outputs a "ON signal" when the driver of the vehicle turns on the engine, and outputs a "OFF signal" when the vehicle is turned off to detect that the vehicle is turned on or off. .

On the other hand, the controller 80 is configured to operate the second high voltage generator 55 of the ion generator 50 when the "starting temperature signal" is input from the start detecting means 90.

In particular, by operating the second high voltage generator 55, a high voltage pulse may be generated in the second high voltage generator 55, and the generated high voltage pulse may be applied to the second ion generator 70. In addition, the second ion generator 70 to which a high voltage pulse is applied may generate negative ions and positive ions. Therefore, as the generated anions and cations flow into the air filter 20, the air filter 20 can be sterilized and deodorized.

According to the start detecting means 90 and the controller 80, when the vehicle is turned on, negative and positive ions are discharged upstream of the air filter 20, and when the vehicle is turned off, And, since the structure of limiting the release of positive ions, regardless of whether the operation of the air cleaning device, only if the vehicle is turned on, unconditionally releases negative, positive ions to the upstream side of the air filter (20). Therefore, even if the air cleaning device is not operated, it is possible to sterilize and deodorize the bacteria, mold and odors inhabiting the air filter 20.

On the other hand, if the controller 80 operates only the second ion generator operating switch 100 installed on the outer surface of the housing 10, the second high voltage generator 55 receives power from the power supply unit 110. And the second ion generator 70 is configured to be turned on or off independently.

The reason for this configuration is to operate the second ion generator 70 irrespective of whether the air cleaner is operated or whether the vehicle is turned on or off. This is because the air cleaner is not turned on or the vehicle is started. Even if it is not turned on, the bacteria, mold and odors inhabiting the air filter 20 can be sterilized and deodorized.

On the other hand, the power supply means 110 is composed of a battery (not shown) installed in the engine room of the vehicle, and serves to provide power when the ion generator 50 operates.

As another example of the power supply means 110, a solar cell may be used. The solar cell collects solar heat, charges it, and uses it as an energy source, and serves to provide power when the ion generator 50 operates when the vehicle is turned off.

Next, an operation example of the present invention having such a configuration will be described with reference to Figs. 2 to 4. Fig.

First, it is determined whether the vehicle is started (S) (S101). As a result of the determination, when the start of the vehicle of the vehicle is turned on, the second ion generating unit 70 is operated (S103).

In this state, the negative and positive ions are generated in the second ion generating unit 70 regardless of whether the air cleaning device is operated, and the generated negative and positive ions are introduced into the air filter 20 to open the air filter 20. Sterilize and deodorize.

Then, in the state where the second ion generating unit 70 operates, the controller 80 determines whether the air cleaner operating switch 10a is turned on again (S105). As a result of the determination, if it is on, the first ion generating unit 60 is even operated (S107).

Then, negative and positive ions are generated in the first ion generating unit 60, and the generated negative and positive ions sterilize and deodorize the air on the air purification passage 12. In particular, since the negative and positive ions are generated at the same time with the second ion generating unit 70, the sterilization and deodorizing ability of bacteria, mold and odor is maximized.

Meanwhile, in the process of operating the first and second ion generators 60 and 70, the controller 80 determines whether the vehicle is started off (S109).

As a result of the determination, the controller 80 determines whether the second ion generating unit operation switch 100 is turned on again (S111). As a result of the determination, if it is turned on, the second ion generating unit 70 is continuously operated, and the first ion generating unit 60 is stopped (S113).

Then, negative and positive ions are continuously generated only in the second ion generating unit 70, and the generated negative and positive ions continuously sterilize and deodorize the air filter 20. In particular, negative and positive ions are independently generated regardless of whether the air cleaning device is operated and whether the vehicle is started or turned off. Therefore, the air filter 20 is continuously sterilized and deodorized regardless of the operation of the air cleaning device and the on / off of the vehicle starting.

When the second ion generator operating switch 100 is turned off (S111-1) in the state where the second ion generator 70 is operating (S111-1), the controller 80 is provided with the first and second ions. All of the generators 60 and 70 are stopped (S115).

Then, both the first and second ion generating units 60 and 70 are stopped, and the generation of negative and positive ions is stopped. Therefore, the sterilization and deodorization of the air filter 20 and the air purification passage 12 are stopped.

On the other hand, in the step (S101) of determining whether the vehicle is started (ON), if the vehicle is turned off (OFF), the controller 80, the second ion generator operating switch 100 is turned on ( It is entered into the step S111 to determine whether it is ON), and the operation thereafter is the same as described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
