Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner having an air cleaning function, and more particularly to an air conditioner having a rotary metal roll filter disposed on the windward side of a heat exchanger in an indoor unit.

[0002]

2. Description of the Related Art Conventionally, an air conditioner with an air purifying function has been equipped with a prefilter made of a net made of synthetic resin fiber, a dust collector and a deodorizing member. I try to clean it by washing with water every week.

[0003]

However, in order to clean the above prefilter, it is necessary to remove or install the prefilter from the main body of the air conditioner, which is troublesome and time-consuming, and sometimes cleaning is required. Sometimes you forget.

Therefore, if the pre-filter is not cleaned, dust will gradually accumulate and the pressure loss will increase, so that the air conditioner cannot be operated under the optimum conditions, which eventually leads to excessive use of energy. Become.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an air conditioner capable of preventing dust from accumulating on a filter and operating under optimum conditions.

[0006]

In order to solve the above-mentioned problems, an air conditioner according to claim 1 of the present invention includes a rotary metal roll filter disposed on the windward side of a heat exchanger in an indoor unit. And a dust removing member that comes into contact with the metal roll filter to remove dust on the metal roll filter.

The air conditioner according to claim 2 of the present invention is
The indoor unit includes a rotary metal roll filter arranged on the windward side of the heat exchanger, and a dust incineration member for incinerating dust on the metal roll filter near the metal roll filter.

[0008]

In the first aspect of the present invention having the above-mentioned structure, since the dust adhering to the metal roll filter is removed by the dust removing member, it is possible to prevent the dust from accumulating on the metal roll filter.

In the second aspect of the present invention, since the dust adhering to the metal roll filter is incinerated by the dust incineration member, it is possible to prevent dust from accumulating on the metal roll filter as well.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing a first embodiment of an air conditioner according to the present invention. FIG. 1 shows an indoor unit 1 of an air conditioner, in which the heat exchanger 2
a and 2b are arranged so as to be inclined and upright, respectively. An indoor fan 3 is arranged at approximately the center of the indoor unit 1.

On the windward side of the heat exchangers 2a and 2b, there are arranged a drive roller 5, a guide roller 6 and a lower roller 7 which are rotationally driven by a drive motor 4, and the drive roller 5, the guide roller 6 and the lower roller. A metal roll filter 8 made of, for example, mesh aluminum or stainless steel is wound around 7, and the pressure loss of the metal roll filter 8 is 0.3 to 0.5 mmAq. Then, the drive motor 4 is driven and the drive roller 5 is rotationally driven, whereby the metal roll filter 8 moves endlessly.

A dust collector 9 is arranged between the heat exchanger 2a and the metal roll filter 8, and a deodorizing member 10 is arranged between the heat exchanger 2b and the metal roll filter 8. The deodorizing member 10 removes gaseous indoor pollutants that cannot be collected by the metal roll filter 8, and as shown in FIG. 2, the deodorizing agent 10a such as activated carbon is used.
And a low temperature oxidation catalyst 10b, and a deodorant 10a.
Low temperature oxidation catalyst for gaseous indoor pollutants adsorbed by
It is deodorized by 0b and is discharged to the outside of the machine.

A dust tray 11 is attached near the lower roller 7, and the dust tray 11 has a suction port 1 for a cleaner.
Two are provided. Further, as shown in FIG. 3, a brush 13 as a dust removing member comes in contact with the metal roll filter 8 in the lower roller 7 along the width direction thereof.

Therefore, the dust scraped off by the brush 13 is collected in the dust tray 11 and is easily removed by operating the cleaner by attaching the suction port of the cleaner to the suction port 12 for the cleaner. To be done.

Next, the operation of this embodiment will be described.

The drive motor 4 is driven by a control signal from a control circuit (not shown), and the drive roller 5 is rotationally driven, whereby the metal roll filter 8 moves in the direction of the arrow. By moving the metal roll filter 8 for a certain period of time before the start of operation (or after the end of operation) or at all times, for example, a new filter portion always collects dust in the air in the room.

The dust adhering to the metal roll filter 8 is removed by the brush 13 of the lower roller 7 which is in contact with the metal roll filter 8 and then stored in the dust tray 11.

Further, the dust collected in the dust tray 11 is sucked by the cleaner through the cleaner suction port 12. Here, the fact that a predetermined amount of dust has accumulated in the dust tray 11 is notified by turning on a display lamp (not shown). The lighting timing of the display lamp may be synchronized with the time for rotating the metal roll filter 8 for, for example, 500 hours.

As described above, according to this embodiment, the deodorizing member 1
By providing the low temperature oxidation catalyst 10b of 0, generation of odor can be suppressed. Further, according to the present embodiment,
The metal roll filter 8 and the deodorizing member 10 do not require maintenance because they are configured as described above.

FIG. 4 shows a second embodiment of the air conditioner according to the present invention. The same parts as those in the first embodiment will be described with the same reference numerals.

In this embodiment, the brush 1 of the first embodiment is used.
Instead of 3, a ceramic heater 20 with a high temperature oxidation catalyst as a dust incineration member is provided in the lower roller 7 in the vicinity of the metal roll filter 8 along the width direction thereof.

Therefore, the dust adhering to the metal roll filter 8 is incinerated by the ceramics heater 20 in the vicinity of the metal roll filter 8 in the lower roller 7 and falls onto the dust tray 11. At that time, the generated odor is deodorized by the high-temperature oxidation catalyst coated on the ceramic heater 20, and the incineration residue is stored in the waste tray 11. The rest of the configuration and operation are the same as in the first embodiment, so a description thereof will be omitted.

The present invention is not limited to the above-mentioned embodiments, but various modifications can be made. For example, both the brush 13 and the ceramic heater 20 with a high temperature oxidation catalyst are provided, and dust burned by the ceramic heater 20 is removed. If it is removed by the brush 13, the accumulation of dust can be prevented more reliably.

[0025]

As described above, according to the first aspect of the present invention.
The air conditioner includes a rotary metal roll filter arranged on the windward side of the heat exchanger in the indoor unit, and a dust removing member that comes into contact with the metal roll filter to remove dust on the metal roll filter. The air conditioner according to claim 2 is provided with a rotary metal roll filter disposed on the windward side of the heat exchanger in the indoor unit, and dust on the metal roll filter near the metal roll filter. Since the dust incineration member for incineration is provided, according to each of the claims, it is possible to prevent clogging of the metal roll filter and always operate under optimum conditions. As a result, energy saving can be achieved.

According to the air conditioner of the second aspect, since the dust on the metal roll filter is incinerated, it is possible to remove harmful substances such as mold fungi, allergens and carcasses of mites in the dust, which is excellent in the room. The environment can be maintained.
