The present invention relates to an air conditioner, and more particularly, to an air conditioner capable of performing an air cleaning operation independently of an air conditioning operation, but having an enhanced air cleaning function.

A conventional air conditioner is provided with a single inlet and equipped with a filter to clean the indoor air by filtering dust and the like sucked into the air conditioner during operation of the air conditioner. However, such an air conditioner could not use a filter capable of filtering out fine particles such as a HEPA filter to enhance air cleaning ability. The reason for this is that the use of a filter that acts as a large resistance in the flow of air, such as a HEPA filter, causes a pressure loss in the air flow and lowers the pressure discharged from the discharge port. This is because it is degraded. For this reason, the air-cleaning ability was inferior to the air-conditioning capacity by using a filter with low pressure loss, and the air-cleaning function could be performed only during the air conditioning operation of the air conditioner.

In general, the air-conditioning capacity of the air conditioner is represented by the equilibrium, and the equilibrium representing the air-conditioning capacity indicates that it is possible to maintain a constant temperature of the indoor space having a normal size. For example, a 15-flat air conditioner is an air conditioner that has the ability to maintain the temperature of a 15-pyeong indoor space.

However, the Consumer Protection Agency recently announced that the air cleaning capacity of the air conditioner with the air cleaning function is significantly lower than the cooling and heating capacity. As described above, although the air conditioning and air-conditioning capacity of the air conditioner having the air cleaning function is different, the consumer can cool and heat the 15-square-foot indoor space as well as the 15-pyeong indoor space. Announced that there is a risk of misunderstanding by consumers because it can be considered as air cleaning.

Both sides of the suction panel 11a are provided with a first suction port 20 for suctioning indoor air during the heating and cooling operation, and a second suction hole 30 for suctioning indoor air during the air cleaning operation is provided on the front surface of the suction panel 11a. ) Is provided. The first inlet 20 is provided with hinge shafts formed at upper and lower portions thereof to rotate the first auto shutter 21 to open and close the first inlet 20, and to slide up and down at the second inlet 30. A second auto shutter 31 is installed to open and close the second suction port 30.

The upper part of the discharge panel 11b is provided with a discharge port 12 through which the indoor air sucked into the first and second suction ports 20 and 30 is discharged through the inside of the cabinet 10, and the discharge air is discharged into the discharge port 12. The blade 13 for adjusting the discharge direction of the is provided.

As shown in FIGS. 2 and 3, the inside of the cabinet 10 is located at a lower rear side of the cabinet 10 to generate pressure so that indoor air is sucked from the first and second suction ports 20 and 30 ( 15) and an upper end thereof are disposed on the upper rear wall of the cabinet 10, and a lower end thereof is supported by a partition plate 17 located in the center of the cabinet 10 to heat-exchange the indoor air sucked into the cabinet 10. (16) is provided.

Since the suction ports 20 and 30 and the discharge ports 12 are partitioned by partition plates 17 which divide the inside of the cabinet 10 up and down, the indoor air sucked through the suction ports 20 and 30 is always a heat exchanger ( It is discharged to the discharge port 12 via the 16.

A pre-filter 22 for filtering large dust sucked through the first suction port 20 is provided inside the first suction port 20 provided on both side surfaces of the suction panel 11a.

The grille 32 is installed at the second suction opening 30 provided at the front of the suction panel 11a, and the filter guide 34 having a plurality of guide grooves 34a is provided at the rear side of the grille 32. A plurality of filters 33 for cleaning the air sucked through the two inlets 30 is easily removable in a sliding manner.

The activated carbon filter 33b and the HEPA filter are inserted into the filter guide 34 in this order. In the present embodiment, three filters as described above are used, but other types of functional filters may be used in combination to suit the purpose of the air cleaning function.

The air conditioner as described above may be operated in three operation modes. Hereinafter, an operation of the air conditioner according to the first embodiment will be described.

In the cooling and heating operation mode for cooling and heating the room, the first suction opening 20 is opened, the second suction opening 30 is closed, and the refrigerant flows to the heat exchanger 16. Therefore, the indoor air is sucked into the cabinet 10 only through the first suction port 20, and the air sucked into the cabinet 10 is heat-exchanged while passing through the heat exchanger 16 and discharged through the discharge port 12. As such, since the air sucked through the first suction port 20 only needs to pass through the prefilter 22 installed inside the first suction port 20, pressure loss hardly occurs while passing through the prefilter 22. Heating and cooling capacity is not lowered.

 In the air cleaning operation mode for cleaning indoor air, the first intake 20 is closed, the second intake 30 is opened, and the refrigerant does not flow to the heat exchanger 16. Therefore, indoor air is sucked into the cabinet 10 only through the second suction port 30, and the air sucked into the cabinet 10 passes through the plurality of filters 33 and is discharged through the discharge port 12. As such, the air flowing only through the second intake port 30 must pass through the plurality of filters 33, so the air cleaning ability is excellent, and since the refrigerant does not flow through the heat exchanger 16, the discharge port 12 is not exchanged. Discharged through.

In the simultaneous heating / cooling and air-cleaning operation mode for cooling and cooling indoor air, both the first suction opening 20 and the second suction opening 30 are opened, and the refrigerant flows to the heat exchanger 16. Therefore, some of the indoor air is sucked into the cabinet 10 through the first suction port 20, and some is sucked into the cabinet 10 through the second suction port 30. Since the air sucked through the second suction port 30 passes through the plurality of filters 33, the air cleaning function is performed, and the cooling and heating function is performed while passing through the heat exchanger 16. At this time, since the first inlet 20 is also open at the same time, the air sucked through the first inlet 30 compensates for the pressure loss generated while passing through the plurality of filters 33 installed in the second inlet 20, thereby cooling and heating. The deterioration of the ability is prevented.

4 to 5 disclose an air conditioner according to a second preferred embodiment of the present invention. The same symbol is used for the same part as the air conditioner according to the first embodiment, and the description of the same part is omitted.

As shown in FIG. 4, the air conditioner according to the second embodiment is provided with a suction panel 11a and a discharge panel 11b at the lower and upper fronts of the cabinet, respectively, and air-conditioning operation is provided on both sides of the suction panel 11a. The first suction port 20 for inhaling indoor air is provided, and the second suction port 30 for inhaling indoor air during clean operation is provided at the front side of the first suction port 20. The first inlet 20 is provided with a first auto shutter 21 for opening and closing the first inlet 20 in a rotational manner, and the second inlet 30 with a second opening 30 in a rotational manner. 2, the auto shutter 31 is installed.

As shown in FIG. 5, a partition wall is divided into a first space 41 communicating with the first suction opening 20 and a second space 42 communicating with the second suction opening 30 in the cabinet 10. 40) is installed. The partition wall 40 is provided with an opening 45 to allow air to flow from the second space 42 to the first space 41, and guide grooves to detachably attach the plurality of filters 33 to the rear side of the opening 45. The filter guide 34 in which 34a was formed is provided.

A pre-filter 22 for filtering large dust sucked through the first suction opening 20 is installed inside the first suction opening 20, but is sucked through the second suction opening 30. Since air is sucked into the cabinet 10 through the plurality of filters 33, a separate filter does not need to be installed.

The air sucked through the first suction port 20 does not pass through the second space 42, but the air sucked through the second suction port 30 passes through the second space 42 and thus, the first space 41. Since it must pass through a plurality of filters 33 installed between the second space 42 and performs the air cleaning function.

Since the operation of the air conditioner according to the second embodiment configured as described above is the same as the first embodiment, it will be omitted below.

Thus, by providing two suction ports 20, 30 on the side of the suction panel 11a, the front design can be varied.

As described above, according to the air conditioner according to the present invention, since the inlet is separated into the first inlet and the second inlet, the air cleaning operation can be performed independently of the heating and cooling operation, and the blower fan used during the heating and cooling operation is used as it is.
