The present invention relates to a car aroma device using an air filter, and more particularly, the air filter of the air filter installed in the blower of the car air conditioner includes the solid particles of the solid particles and at the same time, By attaching a detachable heating plate to the air filter for heating and vaporizing the air freshener, the fragrance of the air freshener is naturally released into the car interior together with the air purified by the air filter, thereby creating a car interior environment while driving the car. The present invention relates to a vehicle air conditioner for maintaining comfort.

In general, when driving a car, various harmful substances such as bacterial dust and soot gas generated on the road are introduced into the car, and especially when the heater or air conditioner is operated on a cold or wet day, odors and bacterial dust generated at this time As it flows into the interior of a differential car, it is exposed to an environment that can only cause discomfort to a driver or a passenger.                         

Accordingly, the vehicle air conditioner is equipped with an air filter for supplying purified air to the driver or the passenger by preventing the above harmful substances from entering the interior of the vehicle.

1 is a cross-sectional view showing an example in which an air filter is attached to a blower of a general vehicle air conditioner.

As shown in FIG. 1, the blower has an indoor air inlet 51 and an outdoor air inlet 52 formed at both sides of the blower, and is rotated between the indoor air inlet 51 or the outdoor air inlet 52. ) And an air intake box 54 having a switching door 53 for selectively opening and closing the outdoor air inlet 52, and a scroll case 55 installed below the air intake box 54. ), A bell mouth 56 installed between the air intake box 54 and the scroll case 55, and installed at the inner center of the scroll case 55, wherein the indoor air inlet 51 or Blower 57 which blows air from the outdoor air inlet 52 in the axial direction and blows it radially toward the discharge port of the scroll case 55, and the bottom surface of the scroll case 55 so as to rotate the blower 57. Installed through the Air filter 59 installed in the lower end of the air intake box 54 to remove dust or harmful components contained in the air flowing through the motor 58 and the air intake box 54. It consists of).

Therefore, when the motor 58 is driven, the suction force generated by the rotation of the blower 57 is generated, and the outside air flows through the indoor air inlet 51 or the outdoor air inlet 52 by the suction force. After being introduced into the container, the filter is filtered through the air filter 59, and then flows into the scroll case 55 through the bell mouse 56. In this state, the air filtered by the air filter 59 is blown through the discharge port of the scroll case 55 toward the air conditioner case (not shown) where the heat exchanger (not shown) is installed and discharged into the vehicle interior.

As described above, by installing the air filter 59 in the blower, the air filter 59 can remove not only harmful substances but also odors such as odors. In particular, in the case of running in a state in which the interior is sealed with the outside, especially during the summer rainy season, it is not possible to sufficiently remove odors such as odor generated as the cleanliness of the indoor air decreases.

Accordingly, drivers often open windows to ventilate, or use external air fresheners containing air fresheners at appropriate locations in the car, such as the instrument panel in front of the car or the shelves behind the rear seats of the car. It is installed separately to purify the air inside the car.

However, since the fragrance container as described above is mostly attached by a double-sided tape attached to the bottom surface, when the adhesive performance of the double-sided tape is degraded, not only is it easily detached from the attachment position, but also the traces of attachment remain. It might hurt the appearance. In addition, since the fragrance emanating from the fragrance container diffuses intensively only in the vicinity to which the fragrance container is attached, the fragrance is not evenly distributed in the interior of the vehicle, and rapid fragrance is not achieved, especially when the driver does not use the vehicle for a long time. There was a problem that the fragrance is made unnecessary waste of fragrance.                         

As a means to solve this problem, conventionally, there has been proposed an electrically operated fragrance for artificially emitting aroma by receiving a separate power from the power supply.

2 and 3 show, as an example, a block diagram and a circuit diagram of a conventional directional device used by being inserted into a cigar jack of an automobile.

As shown in Fig. 2, the conventional directional device 60 includes a main body 61 having a connection terminal inserted into a power supply unit 70, which is a cigar jack, in which a thermally reactive air freshener 80 is embedded, and the main body 61. A fragrance cover 62 for discharging and blocking the fragrance 80, a fragrance selection switch 63 for opening and closing the fragrance cover 62, and a vicinity of the fragrance 80; It consists of a coil for heating the fragrance 80.

In the conventional directional device, as shown in FIG. 3, when the driver turns on the directional selector switch 63, the directional cover 62 is opened, and thus the power terminal and the directional device of the power supply unit 70 are opened. While the fragrance drive switch 64 connecting the connection terminal of 60 is turned on, power is supplied to the coil 65 provided in the fragrance device 60. The coil 65 is heated by the supplied power, and as the coil 65 is heated, the fragrance emitted from the air freshener 80 diffuses into the vehicle interior through the outside of the main body.

However, such a conventional fragrance device, because it must be installed separately in the interior of the vehicle, such as the external air freshener container, can damage the aesthetics, and for the operation, the driver or passenger must insert directly into the cigar jack and artificially manipulated In addition to having the advantage, in order to emit a fragrance, a coarse electrical circuit part, such as a coil or a switch, must be provided, and furthermore, there is a problem such that it can no longer be used in case of failure of the electric circuit part.

Accordingly, the present invention has been made to solve the above-described problems, and includes a fragrance integrated in an air filter installed in a general air conditioner without installing a separate fragrance device in a vehicle interior or a separate operation by a driver. By doing so, the aroma of the vaporized air freshener with the air purified by the air filter during the driving of the car is evenly distributed throughout the interior of the vehicle, and the purpose is to keep the environment of the vehicle interior at all times comfortable.

In order to achieve the above object, the present invention is sucked by the drive of the air filter composed of a filtration member folded in a zigzag form and a frame installed along the circumference of the filtration member so that the mountain and the valley is formed continuously. In the air conditioner for a vehicle air conditioner provided on the flow path of air, the heat transfer plate for integrally embedding the air freshener of the solid particles in the acid and the valley of the filtration member of the air filter, to heat and vaporize the air freshener of the solid particles And detachably attached to the frame to contact the filtration member of the air filter.

In addition, the present invention is the vehicle air conditioner directional device, wherein the heat transfer plate is installed across the filter member of the air filter, the support portion is formed so that the fitting portion is detachably fitted to both ends of the frame of the air filter And an insertion member inserted into each of the bones of the filtration member of the air filter.

In addition, the present invention is the vehicle air conditioner directional device, the insertion member is characterized in that the protrusion formed on the inner surface of the support in the same shape as the overall shape of the bone of the filter member of the air filter.

In addition, the present invention is characterized in that the heating device for the vehicle air conditioner, the heating plate is attached to the heating element, the heating plate is heated by the heat generated by the power applied to the heating element.
