Problems solved by technology

In addition, if regular maintenance is not performed, dust accumulates in the air filter 904 and the ventilation resistance of the sucked air increases, so that the performance of the air conditioner decreases and the power consumption increases.
[0006] In addition, in the structure described in Patent Document 1, since the dust adhering to the belt-shaped filter wound up and down by the drive motor is recovered into the dust box, it is necessary to remove the dust after the dust exceeds the limit in the dust box. There is a problem that regular maintenance is required because the dust is discarded before the amount is kept.

no. 1 approach

[0060] Figure 5 A flowchart showing the automatic cleaning control of the air filter according to the first embodiment of the present invention is given.

[0061] like Figure 5 As shown, in step 501, at first it is determined whether there is an instruction to perform automatic cleaning of the air filter immediately, if yes, then enter step 502, and implement automatic cleaning of the filter, and if not, then return to step 501.

[0062] In the first embodiment, the dust on the air filter can be sucked by the suction fan from the suction nozzle at the time desired by the user through the operation of the remote control or the like, and then passed through the suction duct and the exhaust duct. Since it is exhausted to the outside, the cleaning work of the air filter can be easily performed, and the convenience can be improved.

no. 2 approach

[0064] Image 6 A flowchart showing the automatic cleaning control of the air filter according to the second embodiment of the present invention is given.

[0065] like Image 6 As shown, the normal operation is started, and it is determined in step 601 whether there is a stop instruction, if yes, then enter step 602, if not, then return to step 601. In step 602, it is determined whether automatic cleaning of the filter is set, if yes, proceed to step 603, and if not, stop. In step 603, it is determined whether automatic cleaning of the filter is set when the normal operation is stopped, and if yes, proceeds to step 604, and if not, stops. In step 604, it is determined whether the accumulated normal operation time is longer than a predetermined time (for example, 24 hours), if yes, proceed to step 605, and if not, stop. In step 605, determine whether to manually stop, if yes, then go to step 606, if not, go to step 608. In step 606, it is determined whether automatic clean...

no. 3 approach

[0071] Figure 7 A flowchart showing the automatic cleaning control of the air filter according to the third embodiment of the present invention is given.

[0072] Such as Figure 7 As shown, the normal operation is started, and it is determined in step 701 whether there is a stop instruction, if yes, then enter step 702, if not, then return to step 701. In step 702, it is determined whether automatic cleaning of the filter is set, if yes, proceed to step 703, and if not, stop. In step 703, it is determined whether automatic cleaning of the filter is set when the normal operation is stopped, and if yes, proceeds to step 704, and if not, stops. In step 704, it is determined whether a predetermined cumulative time (for example, 24 hours) has elapsed since the last automatic cleaning of the air filter, and if yes, proceed to step 705, and if not, stop. In step 705, it is determined whether the accumulated normal operation time is longer than a predetermined time (for example, ...

Abstract

An air conditioner having an indoor unit with an automatic air filter cleaning function. The air conditioner has an air filter for collecting dust in air and a suction nozzle capable of moving along the air filter, in a left-right direction of the indoor unit, and having a suction nozzle in which a suction hole for sucking dust adhered to the air filter is formed. Further, the air conditioner hasan operation means for causing automatic cleaning of the air filter to be immediately performed or, alternatively, the air conditioner has an operation means for selecting the start and stop of normaloperation including at least cooling operation and heating operation, which enables automatic cleaning of the air filter while the normal operation is stopped.

Description

technical field [0001] The present invention relates to an air conditioner having an indoor unit with an automatic cleaning function of an air filter. Background technique [0002] Figure 9 shows the indoor unit 901 of the conventional air conditioner, such as Figure 9 As shown, the air sucked by the fan 902 is cooled or heated in the heat exchanger 903, and then sent to the room. In order to prevent the dust floating in the inhaled air from entering the main body of the indoor unit 901, an air filter 904 is provided on the back of the suction port of the indoor unit 901. The air filter 904 is detachably constructed so that it can be cleaned by hand. Attached dust. [0003] In addition, as an air conditioner that is easy to clean the air filter, there is known an air conditioner in which a filter device is provided on the back of the suction panel suction port. A filter, a dust removal member for removing dust adhering to the filter, and a dust collecting box for collect...
