The present invention relates to a vehicle air cleaning device, and more particularly, to increase the amount of anions and cations generated when the humidity in the room increases, which can effectively suppress the growth of bacteria and fungi and the generation of odor caused by the increase in humidity in the room. It relates to a vehicle 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 in an indoor ceiling 1 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 negative ions and cations, and spaces toward the main body 42, the high voltage generator (not shown) and the air purifying passage 12 embedded in the main body 42. And first and second discharge electrodes 44 and 46 extending therebetween.

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 enable sterilization and deodorization treatment of various bacteria and molds in the air flowing along the air purification passage 12. Accordingly, the interior of the vehicle The cleanliness of the air discharged to the air is created to create a comfortable interior environment of the vehicle.

And the loop type air cleaning device is provided with the control part 50 which controls the ion generator 40. As shown in FIG.

The controller 50 includes a microcomputer and a driving circuit, and alternately controls the ion generator 40 alternately between a clean mode and an ion mode.

The clean mode is a mode for increasing the amount of positive and negative ions to increase the sterilization effect of indoor air.The mode of negative and positive ions is equal to the mode, and the ionic mode reduces the amount of positive and negative ions to discharge the room. As a mode for reducing the amount, a mode in which the number of anions is larger than a cation.

The controller 50 alternately controls the ion generator 40 alternately between the clean mode and the ion mode to maximize the effect of sterilization and deodorization of the indoor air and to maximize the generation of cation water harmful to the human body. Reduce.

However, such a conventional air cleaner has a structure in which the ion generator 40 is controlled in a clean mode and an ion mode in spite of the extremely high humidity inside the vehicle, despite the bad smell in the vehicle interior and the rapid growth of bacteria and mold. Therefore, it is pointed out that the sterilization and deodorization process that can effectively sterilize odors, bacteria, molds generated in the interior of the vehicle.

That is, the conventional air cleaning device sterilizes and deodorizes indoor bacteria and odors using the ion generator 40, and sterilizes and deodorizes alternately between clean mode and ion mode. However, since the ion mode is a state in which the amount of generation of negative and positive ions is reduced, when the clean mode and the ion mode are operated alternately, there is a disadvantage that the treatment efficiency of bacteria, mold and odors in the room is relatively lowered. In particular, when the indoor humidity is very high, the bacteria and fungi in the room rapidly grow and the occurrence of odors is intensified. There is a problem in that the rapid growth of bacteria and molds and odors is insufficient to remove.

The present invention has been made to solve the above conventional problems, the object is, when the humidity in the room is high, by maintaining the ion generator in a clean mode to increase the negative, cation generation, according to the increase in room humidity It is to provide a vehicle air cleaning device that can effectively suppress the growth of bacteria and fungi and the generation of odors.

Another object of the present invention is to provide an air cleaning device for a vehicle that can keep the indoor environment of a vehicle at all times comfortable by suppressing the growth of bacteria and mold and odors in the room when the humidity in the room rises.

In order to achieve the above object, the present invention comprises an air cleaning device for purifying the air in the room, and a defogging device for removing the fog of the glass formed when the humidity in the room, the air cleaning device, It has a housing, and ion generator for disinfecting and deodorizing bacteria and mold in the air by releasing negative and positive ions into the air of the air purification passage, the ion generator is a clean mode for increasing the discharge amount of negative, positive ions In the vehicle operated in ion mode to reduce the amount of discharge of positive and negative ions, an anti-fog device for detecting whether the anti-fog device is operated to remove the fog formed on the glass when the humidity in the room increases.

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 (the same components will be described with the same reference numerals).

2 and 3 is a view showing a vehicle air cleaning device according to the present invention. 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 FIG.

The air cleaning device includes a housing 10. The housing 10 is installed on the indoor ceiling 1 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.

The air cleaning device includes an ion generator 40 provided on the air purification passage 12. The ion generator 40 includes a main body 42, first and second discharge electrodes extending at intervals toward the high voltage generating unit (not shown) and the air purifying passage 12 embedded in the main body 42 ( 44, 46).

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.

And the air cleaning apparatus is equipped with the control part 50 which controls the ion generator 40. As shown in FIG. The controller 50 includes a microcomputer and a driving circuit, and alternately controls the ion generator 40 alternately between a clean mode and an ion mode.

Clean mode is a mode for increasing the amount of positive and negative ions to increase the sterilization effect of indoor air. The clean mode generates more than 100,000 cationic water and generates anionic water equally or more than cationic water. .

Ion mode is a mode for reducing the amount of positive and negative ions discharged into the room, and generating 30,000 or more cationic water and generating anionic water equally or more than positive ionized water. to be.

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

First, the air cleaning device of the present invention includes a defogging device detecting means for detecting whether a defogging device, for example, an air conditioning system or a heating wire, is operated to remove the defogging of the front and rear glass of the vehicle.

The defogging device detecting means is composed of a defrost mode switch 60 or a mix mode switch 62 or a hot wire switch 64 of the air conditioning system.

The defrost mode switch 60 is a switch for controlling the air conditioning system to discharge the air of the air conditioning system (not shown) in the direction of the windshield. Detect air conditioning systems

The mix mode switch 62 is a switch for controlling the air conditioning system to discharge the air of an air conditioning system (not shown) in the direction of the windshield, and to remove the mist of the windshield when the humidity rises in the room. Detect a working air conditioning system.

The hot wire switch 64 is a switch for controlling the hot wire to heat the rear glass, and detects a hot wire that is operated to remove the fog of the rear glass when the humidity in the room rises.

According to the defogging device detecting means, by detecting the operation of each device for removing the defogging of the front, rear glass, indirectly detect that the indoor humidity of the vehicle is high. In addition, by detecting that the indoor humidity of the vehicle is currently high, it is indirectly detected that bad odors are generated in the interior of the vehicle and that the growth of bacteria and mold is rapid.

2 and 3 again, the air cleaning apparatus of the present invention includes the controller 50 for controlling the ion generator 40 according to the signal input from the defogging device detecting means.

As described above, the control unit 50 is provided with a microcomputer and a driving circuit. When a detection signal is input from the defogging device detecting means, the indoor humidity of the vehicle is very high, bad odor is generated, bacteria and mold It is determined that propagation of the cell is rapidly performed, and a corresponding "clean mode signal" is output, and the ion generator 40 is kept in a clean mode according to the output "clean mode signal".

In particular, by keeping the ion generator 40 in a clean mode, a large amount of negative and positive ions can be released from the first and second discharge electrodes 44 and 46 of the ion generator 40, and a large amount released. Negative and positive ions allow deodorization and sterilization while quickly removing odors and bacteria and fungi in the room.

Here, when the detection signal of the defogging device detecting means is erased, the controller 50 determines that the indoor humidity of the current vehicle is low, cancels the "clean mode signal", and outputs an "alternate mode signal". . Therefore, the ion generator 40 is alternately controlled in the clean mode and the ion mode.

2 and 3 again, the controller 50 of the present invention further includes a timer 70.

The timer 70 counts the time so that the "clean mode signal" of the controller 50 is not immediately erased but is delayed for a preset time even after the detection signal of the defogging device detecting means is erased.

In this way, the delay of the "clean mode signal" of the controller 50 for a predetermined time, and then the reason for erasing, the ion generator 40 in the clean mode for a set time even if each device for removing the fog is stopped. This is to maintain the maximum efficiency of the removal of bacteria, mold and odor remaining in the room.

Next, a control method of the air cleaning apparatus of the present invention having such a configuration will be described with reference to FIGS. 2, 3, and 4.

First, it is determined whether the driver has operated one of the defrost mode switch 60, the mix mode switch 62, and the hot wire switch 64 (S101).

As a result of the determination, if any one of the switches 60, 62, and 64 has not been operated, the controller 50 determines that the indoor humidity of the current vehicle is low and outputs an "alternate mode signal" (S103). The ion generator 40 is alternately controlled in the clean mode and the ion mode according to the "alternative mode signal" (S105).

On the other hand, as a result of the determination, if any one of each switch (60, 62, 64) has been operated, the control unit 50 is now very high indoor humidity of the vehicle, bad odor is generated and the growth of bacteria and mold is rapidly made In operation S107, it is determined that the operation is performed, and a "clean mode signal" corresponding thereto is output. Then, the ion generator 40 is maintained in the clean mode according to the output "clean mode signal" (S109).

In this state, since the ion generator 40 maintains a clean mode, it generates a large amount of negative and positive ions, and the generated large amount of negative and positive ions quickly removes odors, bacteria, and mold in the room. Thus, the interior of the vehicle is kept comfortable.

On the other hand, while the ion generator 40 maintains the clean mode state, it is again determined whether the switch operation is released (S111).

As a result of the determination, when the switch operation is released, the controller 50 determines that the current indoor humidity of the vehicle is lowered, thereby reducing the bacteria and mold, thereby erasing the "clean mode signal" and outputting an "alternate mode signal" (S103). ). Therefore, the ion generator 40 is alternately controlled in the clean mode and the ion mode (S105).

Meanwhile, the "clean mode signal" is erased while being delayed for a preset time under the control of the timer 70. Therefore, the ion generator 40 removes bacteria, mold and odors in the room while maintaining the clean mode for a predetermined time.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope of the claims.

As described above, according to the air cleaning device for a vehicle according to the present invention, after indirectly detecting the humidity rise in the room through the de-fogging device detecting means, and maintaining the ion generator in a clean mode according to the detected signal Therefore, when the humidity in the room is increased, there is an effect that can increase the amount of cations generated.

In addition, since the generation of ions and cations can be increased with increasing humidity in the room, it has the effect of effectively suppressing the growth of bacteria and mold and the generation of odors due to the increase in humidity in the room.

In addition, by suppressing the growth of bacteria and mold in the room and the occurrence of odor when the humidity in the room rises, there is an effect of always keeping the indoor environment of the vehicle comfortable.
