Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner capable of cooling or heating, and more particularly to an air conditioner for an indoor unit, which is provided with an air filter or an air outlet having an aroma effect. The present invention relates to an air conditioner that can improve the comfort of passengers.

[0002]

2. Description of the Related Art According to Japanese Patent Laid-Open No. 63-194139, an indoor unit has a deodorizing filter having a deodorizing performance for a nitrogen compound type odor and a deodorizing function having a deodorizing performance for a sulfur compound type odor. Although it is described that two odors with a filter are attached and a plurality of different odors are deodorized without any increase in ventilation resistance, no fragrance for canceling offensive odors is described.

[0003]

In the above-mentioned prior art, the deodorizing effect is described, but the aroma that positively adds a scent to the blown air is not described.

An object of the present invention is to provide air conditioning with an aroma effect by providing a filter for the air inlet of an indoor unit, a cassette or the like at the air outlet and providing an air freshener therewith to improve comfort. .

[0005]

According to the present invention, in order to enable fragrance air-conditioning, the filter part is impregnated with fragrance or the fragrance-containing cassette is attached to the panel.

[0006]

[Operation] By recording the reduction rate of the fragrance contained in the filter in the indoor unit control board microcomputer section in advance,
It can be displayed on the remote controller when the usage time, air volume, etc. are calculated and the aroma effect is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention is shown below in FIGS. 1, 3, 5 and 6. FIG. 1 shows an embodiment of the present invention. An air filter 5 with an air freshener is attached to a decorative panel 2 attached to an indoor unit 1 having a heat exchanger 4 and a blower 3. When the air is sucked from the decorative panel 2, the air passes through the air filter 5 with the fragrance and makes the air odorous, passes through the heat exchanger 4, and blows out the odorous air from the outlet of the decorative panel 2. Therefore, air conditioning with an aroma effect is possible.

FIG. 2 shows the relationship between the filter fragrance impregnation amount and the reduction time. The vertical axis shows the remaining amount of air freshener and the horizontal axis shows the time. The amount of fragrance decreases as the usage time increases in a rapid wind.
The use time advances when the wind is weak, but the rate of reduction of the fragrance is smaller than when the wind is windy. By storing this relationship in the control board microcomputer section of the indoor unit of FIG. 1, it is possible to display and notify the remote controller 16 of the replacement time of the air filter 5 with fragrance.

FIG. 3 shows another embodiment of the present invention. Ceiling cassette type indoor unit with four-way outlet When the air sucked from the inlet 6 of the decorative panel 2 is heat-exchanged and blown out from the outlet 7, the cassette type with the fragrance shown in FIG. The odor is supplied from the box 8 through the scent passage 9 to add scent to the air. These allow aroma air conditioning. Further, a scent adjusting shutter 10 that can be opened and closed by the pulse motor 11 is provided in the scent passage 9, and a signal can be sent from the remote controller 16 to the pulse motor 11 to adjust the opening / closing amount of the scent adjusting shutter 10. By adjusting the opening / closing amount, it is possible to adjust the fragrance amount and perform fragrance air conditioning according to the taste.

5 and 6 show the inside of the cassette box 8 containing the fragrance. Before use, the fragrance 14 is contained as shown in FIG. 5, and the sensor 15 suspended by the spring 13 and the sensor switch 12 are separated from each other. As the fragrance 14 decreases, the spring 13 contracts, the sensor 15 moves up, and the sensor switch 12 comes into contact with the sensor switch 12 as shown in FIG. The sensor 15 hits the sensor switch 12 and a signal is displayed on the remote controller 16 so that the replacement of the fragrance-containing cassette type box 8 can be known.

The cassette type is easy to replace, and a plurality of different scents are installed at four places, and the pulse motor 11 is used to open and close the scent adjusting shutter 10 to change the use time, place and person. It is possible to select the odor that suits your taste.

[0012]

According to the present invention, the air filter is impregnated with a fragrance or a cassette type fragrance is used for easy replacement, and information is displayed on the remote controller to replace the air. It is possible to provide fragrance air conditioning with improved comfort by making it possible to adjust the amount of scent and scent and select scent.
