Description

  The present invention relates to an air conditioner that automatically cleans an air filter.

  In air conditioners currently in widespread use, the mainstream of air filters installed to collect dust in the air is regularly maintained by cleaning by users or equipment contractors. However, with the recent spread of air conditioners and the promotion of energy saving, air conditioners that automatically clean air filters have been considered.

A device (for example, see Patent Document 1) having a belt-like air filter and a cleaning mechanism that is fed and wound by a motor, and a device in which an air filter and a cleaning mechanism are integrated (for example, see Patent Document 2) are known. A method of controlling the cleaning mechanism that allows these devices to be operated periodically or forcibly has been considered.

  However, in the conventional configuration, since the cleaning mechanism is integrated, it is not easy to attach and detach the air filter from the air conditioner.

  For this reason, when cigarette dust or oil components adhere to the air filter, cleaning with water or detergent becomes necessary, but it must be cleaned with the cleaning mechanism, which is difficult. Even if the cleaning mechanism is combined, the configuration is further complicated, and maintenance such as replenishment of solvent is required, which is not convenient.

  Therefore, it is more practical to remove the air filter and clean the oil component and the like accumulated in the long term, and it is preferable that the air filter can be attached and detached.

  When such a configuration is adopted, human influences are included when the air filter is attached / detached. Therefore, it is necessary to devise a device that grasps the mounting state of the air filter and facilitates mounting.

  This invention solves the said subject, and when using the removable air filter for the cleaning mechanism control apparatus of the air conditioner designed to automatically clean the air filter, the mounting state of the air filter is changed. It aims at providing the air conditioner which can be grasped | ascertained.

  In order to solve the conventional problems, an air conditioner of the present invention is an air conditioner having an air filter that collects dust in the air and a cleaning mechanism that removes dust from the air filter, A moving unit that relatively moves the air filter and the cleaning mechanism; and a mounting state checking unit that checks a mounting state of the air filter, and outputs a result confirmed by the mounting state checking unit during movement by the moving unit. An output means is provided.

In the air conditioner of the present invention, the mounting state confirmation unit confirms the mounting state of the air filter by a change in the load applied to the drive mechanism portion of the moving unit.

  The air conditioner of the present invention displays nothing when the air filter is correctly attached.

  Since the air conditioner of the present invention can easily check the mounting of the air filter when the air filter is attached or detached, the convenience of the user can be improved.

  1st invention is an air conditioner which has an air filter which collects dust in the air, and a cleaning mechanism which removes dust of the air filter, and moves the air filter and the cleaning mechanism relatively And a mounting means confirmation means for confirming the mounting state of the air filter, and an output means for outputting a result confirmed by the mounting state confirmation means during movement by the moving means. The state can be easily confirmed.

  In a second aspect of the invention, particularly in the first aspect of the invention, the attachment state confirmation means confirms the attachment state of the air filter by a change in the load applied to the drive mechanism portion of the movement means.

  In the third invention, in particular, in the first to second inventions, when the air filter is correctly mounted, nothing is displayed, so that the filter can be attached and detached more easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a schematic view of a cleaning mechanism of the present invention, FIG. 2 is a block diagram of control in the first embodiment of the present invention, and FIG. 3 is a flowchart of control.
In FIG. 1, both ends of the cleaning portion 13 have guide portions 12 that can move in the left-right direction so that the removable air filter 11 is automatically cleaned. Therefore, it has a structure that can move in the left-right direction.

  2 and 3, when a filter mounting check signal is transmitted from the remote controller 21 after the air conditioner is turned on (step 31) (step 32), the microcomputer 24 receives the filter mounting check signal (step 32). 33) The cleaning mechanism 27 is driven (step 34), and the mounting state of the filter is confirmed from the driving state of the cleaning mechanism.

  As described above, in the present embodiment, since the cleaning mechanism is driven by a signal from the filter mounting check transmission unit and the filter mounting check transmission unit, the air filter mounting state is determined from the driving state of the cleaning mechanism. Confirmation can be easily performed with a single remote control.

  In addition, the filter mounting state check is not only used by the user when the filter is attached / detached, but can also be used by the installer when installing the air conditioner to prevent defective filter mounting in the initial installation state. .

(Embodiment 2)
In the second embodiment of the present invention, the cleaning unit 13 in FIG. 1 takes the form of a suction type nozzle.

The suction duct 14 and the suction device 15 and the exhaust duct 16 are communicated with the suction nozzle, and the dust sucked from the suction nozzle is discharged from the exhaust duct, so that the dust in the vicinity of the air filter is removed, so that it becomes clean.
As described above, in the present embodiment, the suction nozzle, the suction device communicated with the suction nozzle, and the cleaning device including the exhaust duct are configured to automatically discard dust that has been subjected to suction processing. The dust in the vicinity of the air filter is removed and the air filter is clean, the air filter can be easily attached and detached, and the establishment of success in the filter attachment check is increased.

(Embodiment 3)
2 and 3, when a filter reset signal is transmitted from the remote controller 21 after the air conditioner is turned on (step 31) (step 35), the microcomputer 24 receives the filter reset signal (step 36). Then, the cleaning mechanism 27 is driven (step 37), and the filter is moved out of the air passage.

  As described above, in the present embodiment, when the cleaning mechanism is on the ventilation path of the air filter, the filter reset transmission means for transmitting a signal for driving the cleaning mechanism out of the ventilation path; A filter reset reading output means for reading and outputting a signal from the filter reset transmitting means is provided, and the cleaning mechanism is driven out of the air filter passage by the output from the filter reset reading output means. It will be easier to do.

  This filter reset operation can be used not only when the filter is attached and detached, but also when the cleaning unit 13 is on the ventilation path of the air conditioner during normal operation, and by moving the cleaning unit outside the ventilation path. The ventilation resistance of the ventilation path can be reduced, and the efficiency of air conditioning can be improved.

  As described above, since the air conditioner according to the present invention can check the mounting state of the air filter, it can be applied to a device equipped with a filter such as an air purifier or a humidifier.
