The present invention relates to an ion generator of a vehicle air conditioning system, and more particularly, to reduce the unnecessary energy consumption as much as possible, and more specifically, to the ion generator of the vehicle air conditioning system capable of efficiently sterilizing and deodorizing pollutants contained in the outside air It is about.

The car is equipped with an air conditioning system for controlling the temperature of the room air. This air conditioning system, as shown in Figure 1, has an air conditioning case 10, the air conditioning case 10, the outdoor air inlet 12 for introducing the outside air, and the internal air inlet 14 for introducing the bet And an intake door 15 for selectively opening any one of these internal and external air inlets 12 and 14.

The intake door 15 is rotated to the bet mode position X or the air mode position Y by operating the internal / external air changeover switch 15a in the “bet mode” or “external mode”, and the bet mode position The internal airway inlet 14 is opened at (X), and the outdoor airway inlet 12 is opened at the external air mode position Y. Thus, the bet or the outside air can be selectively introduced.

The air conditioning system includes a blower 20. The blower 20 includes a blower fan 22 and a blower motor 24 for driving the blower fan 22. The blower 20 sucks outside air or inside, and sucks the inside and outside air inside the air conditioning case 10. Blowing into the passage 16.

The air conditioning system includes an evaporator 30 installed in the inner passage 16 of the air conditioning case 10.

The evaporator 30 has a plurality of tubes (not shown) through which the refrigerant can flow, and cools the air passing through the inner passage 16. Thus, cooled air can be introduced into the interior of the vehicle.

The air conditioning system includes an ion generator 40 provided upstream of the evaporator 30.

The ion generator 40 includes an anion discharge electrode 46 and a cation discharge electrode 48 extending at intervals toward the inner passage 16. The anion and cation discharge electrodes 46 and 48 emit high voltage pulses directly into the air of the inner passage 16 to generate anions and cations, respectively.

The ion generator 40 is operated by manipulating the ion switch 40a to generate negative and positive ions, and the negative and positive ions generated in the evaporator 30 may be supplied with bacteria, mold, and odors. To sterilize and deodorize the air being Therefore, the cleanliness of the air supplied to the room is increased to create a comfortable indoor environment.

However, since the conventional ion generator 40 has a structure that is continuously operated when the ion switch 40a is turned on, it is pointed out that a lot of electricity is consumed. In particular, since the ion generator 40 is continuously operated even though the outdoor air introduced into the room is in a clean state, there is a problem in that a large amount of unnecessary energy is consumed, and the fuel economy of the vehicle is increased due to this problem.

In addition, the conventional ion generator 40 is structured to operate only when the ion switch 40a is turned on. Therefore, when contaminated air is introduced while the ion switch 40a is turned off, contamination is caused. There is a problem that the air can not be sterilized and deodorized.

In particular, a large amount of contaminants are introduced when passing through a specific area where air is highly polluted, for example, a tunnel, in an external air mode. At this time, a large amount of contaminants introduced together with the outside air are sterilized and deodorized. The problem of not being able to do this is pointed out.

The present invention has been made to solve the conventional problems as described above, the object of the vehicle, the air conditioning system for reducing the unnecessary energy consumption by configuring to operate selectively only when traveling in a specific area with high air pollution degree To provide an ion generator of.

Another object of the present invention is configured to automatically operate when passing through a specific area where the air pollution is very high even when the ion switch is turned off, so that contaminated outdoor air can be efficiently and efficiently regardless of whether the ion switch is turned on or off. It is to provide an ion generator of a vehicle air conditioning system that can be sterilized and deodorized.

In order to achieve the above object, the present invention provides an air-conditioning case having an airway inlet, an internal airway inlet, and an internal passage, and a motion between an airtight mode position for opening the internal airway inlet and an external air mode position for opening the external airway inlet. A vehicle air conditioning system comprising an intake door and an ion generator for emitting negative and positive ions in the inner passage, the vehicle air conditioning system comprising: an outside air mode detecting means for detecting whether the intake door is in an outside air mode position; Driving position detecting means for detecting a current driving position of the vehicle; When a signal is input from both the outside air mode detecting means and the driving position detecting means, when the driving position of the vehicle input from the driving position detecting means enters a predetermined specific region, the ion generator is turned on and is out of the specific region. And a controller for controlling to turn off the ion generator.

Best Mode for Carrying Out the Invention Preferred embodiments of a vehicle air conditioning system ion generator according to the present invention will be described in detail with reference to the accompanying drawings (the same components will be described using the same reference numerals).

2 is a view showing the ion generator of the vehicle air conditioning system according to the present invention. First, prior to looking at the features of the ion generator according to the present invention, a brief look at the ion generator of the vehicle air conditioning system with reference to FIG.

The ion generator 40 includes an anion discharge electrode 46 and a cation discharge electrode 48 extending at intervals toward the inner passage 16.

The ion generator 40 is operated by operating the ion switch 40a to generate negative and positive ions. Thus, the generated negative and positive ion particles enable sterilization and deodorization of the evaporator 30, and deodorization and sterilization of odors, bacteria and mold in the air.

Next, the features of the ion generator of the vehicle air conditioning system according to the present invention will be described in detail with reference to FIG.

First, the ion generator of the present invention is provided with an outside air mode detecting means 50 for detecting whether the intake door 15 is in the outside air mode position (Y) state.

The outside air mode detecting means 50 is constituted by the inside and outside air changeover switches 15a. The internal and external air switch 15a is a switch for selecting the intake door 15 to the external air mode position Y or the internal air mode position X. The user selects the intake door 15 to the external air mode position Y. Detect switching to

In addition, the ion generator of the present invention includes a traveling position detecting means 60 for detecting a traveling position of the vehicle.

The driving position detecting means 60 is composed of a navigation system and detects where the vehicle is currently traveling.

For reference, the navigation device includes a GPS (Global Positioning System) and a map, and is a device that grasps the current location of the vehicle and displays the location on a map on the display. In particular, the built-in map detects in detail whether the current driving position of the vehicle is in the tunnel or the construction area.

Referring again to FIG. 2, the ion generator of the present invention includes a controller 70.

The controller 70 is equipped with a microprocessor. When a signal is input from both the outside mode detecting means 50 and the driving position detecting means 60, the current driving position of the vehicle input from the driving position detecting means 60. Determines whether the vehicle enters the preset specific zone, and if the driving position of the vehicle is within the preset specific zone, determines that the current vehicle passes through the polluted area, and that the outside air of the polluted area is introduced into the vehicle interior. The ion generator 40 is turned on.

Accordingly, the ion generator 40 can generate negative and positive ions, and the negative and positive ion particles generated can sterilize and deodorize the evaporator 30, and also deodorize and sterilize odors, bacteria and mold in the air. Allow for sterilization.

On the other hand, it is preferable that the specific area built in the controller 70 is set inside the tunnel, the construction site, or the like. This is because the air in the tunnel and the air in the construction site contain a large amount of pollutants.

According to the ion generator of the present invention having such a configuration, since the structure operates only in a place where air pollution is severe, it can be prevented from constantly operating continuously regardless of the degree of contamination of the introduced outdoor air. Thus, unnecessary energy consumption due to continuous operation can be prevented.

In addition, since the structure is operated automatically in a place where air pollution is severe, it is possible to automatically sterilize and deodorize the outside air introduced efficiently without turning on and off the ion switch one by one.

On the other hand, the controller 70, of course, to control to turn off (ON) the ion generator 40 when moving out of a specific area.

The controller 70 controls to increase the amount of ions emitted from the ion generator 40 when the ion generator 40 is turned on before the driving position of the vehicle enters the specific zone. When the deviation from the specific zone is configured to control to return the ion amount to the amount of ion prior to entering the specific zone.

Next, an ion generator control method using the ion generator having such a configuration will be described with reference to FIGS. 2 and 3.

First, in a state in which the driving position of the vehicle is continuously detected from the driving position detecting means 60 (S101), the controller 70 determines whether the intake door 15 is in the outdoor mode position Y (S103).

As a result of the determination, if it is the outside mode position Y, it is again determined whether the driving position of the vehicle input from the driving position detecting means 60 has entered the predetermined specific area (S105).

As a result of the determination, if it is within a specific zone, the current vehicle passes through the contaminated zone, and determines that the outside air of the contaminated zone is introduced into the interior of the vehicle, thereby turning on the ion generator 40 (S107).

Then, the ion generator 40 generates a large amount of negative and positive ions, and the generated negative and positive ion particles enable sterilization and deodorization of the evaporator 30, and the outside air introduced into the air conditioning case 10. Deodorization and sterilization of odors, bacteria and fungi.

As a result, when passing through the contaminated area, air introduced from the contaminated area can be automatically deodorized and sterilized efficiently. Therefore, the indoor atmosphere of the vehicle can be kept comfortable at all times.

On the other hand, the controller 70 controls to increase the amount of ions emitted from the ion generator 40 when the ion generator 40 is turned on before the driving position of the vehicle enters the specific zone.

2 and 3 again, in the state where the ion generator 40 is turned on, the controller 70 determines again whether the traveling position of the vehicle is out of the specific area (S109).

If it is determined that the deviation from the specific area, the ion generator 40 is turned off (S111).

At this time, the controller 70, when the ion generator 40 is turned on before the driving position of the vehicle enters the specific zone, when the position of the vehicle deviates from the specific zone, the controller 70 returns the ion amount to the ion amount before entering the specific zone. To control it.

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.

As described above, according to the ion generator of the air conditioning system for a vehicle according to the present invention, since the structure operates only in a place where air pollution is severe, it is possible to prevent continuous operation regardless of the degree of contamination of the introduced outdoor air. Therefore, there is an effect that can minimize unnecessary energy consumption due to continuous operation.

In addition, since the structure is operated automatically in a place where air pollution is severe, there is an effect that can automatically sterilize and deodorize the outside air introduced efficiently without turning on and off the ion switch.
