The ion generator 40 includes a first discharge electrode 44 and a second discharge electrode 46 which are provided at intervals on the main body 42. The first and second discharge electrodes 44 and 46 extend through the air conditioning case 10 and extend toward the internal passage 12, and emit high voltage pulses directly into the air of the internal passage 12 to obtain negative / Each cation is generated.

The cluster ion generator 40 having such a configuration radiates high voltage pulses into the air to generate negative / positive ions. Therefore, the generated negative / cationic particles can flow into the evaporator 30 while flowing along the inner passage 12.

Next, look at in detail with respect to the ion generator structure according to the present invention.

3 and 4, the safety device of the present invention is spaced apart from the first fixed terminal 50 and the first fixed terminal 50 installed in the main body 42 of the ion generator 40. A second fixing terminal 52 corresponding to the above is provided.

The first fixed terminal 50 is fixedly installed inside the main body 42 and is electrically connected to the power input unit 42a. Since the first fixed terminal 50 is electrically connected to the power input unit 42a, the first fixed terminal 50 is in a state where electricity of the power input unit 42a is applied.

The second fixed terminal 52 is fixedly installed inside the main body 42 and is electrically connected to the first and second discharge electrodes 44 and 46. The second fixed terminal 52 is electrically connected to the first fixed terminal 50 by the movable terminal 54 to be described later, and thus applies electricity to the first and second discharge electrodes 44 and 46. .

The safety device of the present invention includes a movable terminal 54 for electrically connecting the first fixed terminal 50 and the second fixed terminal 52.

The movable terminal 54 is a fixed end 54a, one end of which is fixed to the second fixed terminal 52, and the other end is a free end 54b that is movable relative to the fixed end 54a. In particular, the free end 54b is configured to protrude to the outside of the main body 42, as shown in Figure 4, as shown in Figure 3, when the main body 42 is assembled to the air conditioning case 10 It is pressed by a portion 14 of the air conditioning case 10 and has a configuration connected to the first fixed terminal 50 while moving from the first position ("A") to the second position ("B").

Since the movable terminal 54 is structured to be connected to the first fixed terminal 50 by assembling the main body 42 to the air conditioning case 10, when the main body 42 is assembled to the air conditioning case 10, It serves to electrically connect the first fixed terminal 50 and the second fixed terminal 52, so that the electricity of the first fixed terminal 50 through the second fixed terminal 52, the first and second discharge To be applied to electrodes 44 and 46.

On the other hand, in the present invention, the movable terminal 54 is configured to be selectively connected to the first fixed terminal 50 in a state of being fixed to the second fixed terminal 52, but in some cases the first fixed terminal In the state fixed to 50, it can also be comprised with the structure selectively connected to the 2nd fixed terminal 52. As shown in FIG.

3 and 4 again, the safety device of the present invention includes a spring 60 for elastically pressing the free end 54b of the movable terminal 54 in the outward direction of the main body 42.

One end of the spring 60 is supported by the main body 42, and the other end of the spring 60 is supported by the free end 54b of the movable terminal 54. The spring 60 has the first fixed terminal as the free end 54b of the movable terminal 54. Elastic pressing is performed in the direction of the first position ("A") spaced from 50.

The spring 60 elastically pressurizes the free end 54b of the movable terminal 54 in the direction of the first position ("A") spaced apart from the first fixed terminal 50, as shown in FIG. 4. When the main body 42 is separated from the air conditioning case 10, the free end 54b of the movable terminal 54 may be detached from the first fixed terminal 50 while being disconnected from the first fixed terminal 50. It serves to automatically cut off the electricity applied from the fixed terminal 50 to the first and second discharge electrodes (44, 46).

Next, look at the operation example of the present invention having such a configuration as follows.

First, the case in which the ion generator 40 is mounted in the air conditioning case 10 will be described with reference to FIG. 3. The main body 42 of the ion generator 40 is mounted to the air conditioning case 10. Then, the free end 54b of the movable terminal 54 protruding from the main body 42 is pressed against the portion 14 of the air conditioning case 10, and the free end 54b of the pressed movable terminal 54 is removed. It is connected to the first fixed terminal 50 while moving from one position ("A") to the second position ("B").

On the other hand, as the free terminal 54b of the movable terminal 54 is connected to the first fixed terminal 50, the first fixed terminal 50 and the second fixed terminal 52 are electrically connected, and the first fixed terminal 52b is electrically connected. As the terminal 50 and the second fixed terminal 52 are electrically connected, electricity of the power input unit 42a is applied to the first and second discharge electrodes 44 and 46. As a result, the first and second discharge electrodes 44 and 46 generate negative / positive ions, respectively, while radiating high-voltage pulses into the air of the inner passage 12.

Next, the case in which the ion generator 40 is separated from the air conditioning case 10 will be described with reference to FIG. 4. First, the main body 42 of the ion generator 40 is separated from the air conditioning case 10.

The movable terminal 54 restored to " A " automatically disconnects the power applied to the first and second discharge electrodes 44 and 46 while being disconnected from the first fixed terminal 50. FIG.

As a result, since the power applied to the first and second discharge electrodes 44, 46 is automatically cut off, the operation of the first and second discharge electrodes 44, 46 is automatically stopped, and thus, the first and second discharge electrodes 44, 46 are automatically stopped. High voltage does not flow through the second discharge electrodes 44 and 46.

According to the present invention having such a configuration, when the ion generator 40 is mounted in the air conditioning case 10, electricity is automatically applied to the first and second discharge electrodes 44 and 46, and the ion generator 40 is turned on. When separated from the air conditioning case 10, since it is configured to automatically cut off the electricity applied to the first and second discharge electrodes (44, 46), when disassembling and assembling the ion generator 40, the first and second discharge electrodes An electric shock accident due to the high voltage of (44, 46) can be prevented at the source.

The push protrusion 16 is configured to press the free end 54b of the movable terminal 54 while being inserted into the main body 42 of the ion generator 40. In particular, when the ion generator 40 is assembled to the air conditioner case 10, the free end 54b of the movable terminal 54 is pressed into the second position (“B”) while being inserted into the ion generator 40. It serves to contact the first fixed terminal (50).

The safety device of this modified example includes a push protrusion 16 for pressing the movable terminal 54 while being inserted into the ion generator 40, so that the free end 54b of the movable terminal 54 has the main body 42. It does not need to be configured to protrude out of.

In the above described exemplary embodiments of the present invention by way of example, the scope of the present invention is not limited only to these specific embodiments, it can be changed appropriately within the scope described in the claims.

As described above, according to the ion generator structure of the vehicle air conditioning system according to the present invention, since the power applied to the first and second discharge electrode is automatically cut off when the ion generator is separated, the first and second discharge It has the effect of preventing the electric shock accident by the high voltage of an electrode beforehand.
