Description

  The present invention relates to a cleaning mechanism control method for a multi-function device that automatically cleans an air filter.

  At present, with the advancement of energy saving promotion, multi-function devices such as air conditioners that automatically clean air filters have become widespread.

  In such a multi-function device, while various automatic cleaning mechanisms are considered, a mechanism that makes it possible to attach and detach the air filter from the viewpoint of practicality has become the mainstream, Automatic cleaning is performed while moving along the upstream surface of the air filter, and dirt such as oil components that accumulate for a long period of time is removed directly from the air filter. And if that configuration is adopted, human influence will be included when the air filter is attached / detached. Therefore, it is necessary to have a device that makes it easy to install the air filter and a means that can deal with problems when the air filter is inadequate. It has become.

  If the air filter is not properly installed, operating the cleaning mechanism will cause the cleaning mechanism to catch on the air filter and stop the automatic cleaning.Select the driving direction of the cleaning mechanism according to the condition of the air filter being caught. In some cases, the cleaning mechanism is driven outside the air passage of the air filter so that the problem can be solved early and the return can be dealt with (see, for example, Japanese Patent Application No. 2005-293589 of an unpublished company application). ).

  However, in the multi-function device using the conventional control method, when there is a problem in the construction of the air filter, the timing when the problem is noticed is the first cleaning using the multi-function device after starting operation. This means that it has been a while since the user used the multi-function device. Naturally, the user has to deal with the problem, not the contractor, and is inconvenient for the user. There was a problem.

  The present invention solves the above-described conventional problems, and when installing a multi-function device, it is possible to find and deal with an air filter installation failure while there is a contractor, and is a multi-function that is highly convenient for the user. It is an object of the present invention to provide a cleaning mechanism control method for an apparatus.

  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 diagram of a cleaning mechanism of a multi-function device according to a first embodiment of the present invention, FIG. 2 is a block diagram showing a control method of the cleaning mechanism, and FIG. 3 is a flowchart showing the control method. It is shown.

  In FIG. 1, reference numeral 25 denotes a cleaning mechanism mounted on a main body (not shown) of a multifunction device such as an indoor unit of an air conditioner. The cleaning mechanism 25 is detachably attached to the air filter 11 that collects dust. In order to automatically perform cleaning, a suction nozzle 13 for sucking dust accumulated on the upstream surface of the air filter 11 and a guide portion for guiding the suction nozzle 13 to move in the left-right direction and along the air filter 11 12, a suction device 15 communicating with the suction nozzle 13 via the suction duct 14, an exhaust duct 16 having one end connected to the exhaust side of the suction device 15 and the other end opened to the outside, and the suction nozzle 13 in the left-right direction. It is comprised from the drive means 18 to move to.

  Then, by operating the suction device 15 and the driving means 18, dust accumulated on the air filter 11 is sucked from the suction nozzle 13 while the suction nozzle 13 moves on the air filter 11 from one end to the other end. The sucked dust is discharged to the outside from the exhaust duct 16 through the suction duct 14 and the suction device 15, and the dust in the vicinity of the air filter 11 is automatically removed, so that it is easily cleaned. The structure cleaning mechanism.

  2 and 3, in order for the contractor to install the multi-function device in a predetermined place and set the air filter 11 in the multi-function device to perform a test run, a remote control (not shown) and a test run button (not shown) When a predetermined switch is operated to start operation of the multi-function device (step 31), an operation start signal is output from the operation start determination means 21 that determines the start of operation of the multi-function device.

  Here, if the suction nozzle 13 of the cleaning mechanism 25 has not completed one reciprocation, a cleaning mechanism operation completion non-signal is output from the cleaning mechanism operation completion presence / absence storage means 23 (step 32), and the multi-function device is operated. Before the air filter 11 is attached, the suction nozzle 13 is forcibly reciprocated once by the cleaning mechanism drive signal output means 24 in order to confirm whether the air filter 11 is mounted correctly (step 33).

  When the cleaning mechanism operation completion determination unit 22 determines that the one-way operation of the suction nozzle 13 of the cleaning mechanism 25 is completed, the cleaning mechanism operation completion presence / absence storage unit 23 stores the completion of the cleaning mechanism operation (step 34). ), The operation of the multi-function device is started (step 35).

  If the air filter 11 is erroneously attached when the suction nozzle 13 of the cleaning mechanism 25 is reciprocated once, the suction nozzle 13 is caught by the air filter 11 and cannot move in the left-right direction. A signal may be sent to (not shown) to notify the contractor of the problem and encourage the response. When the air filter 11 is caught or when the suction nozzle 13 of the cleaning mechanism 25 stops before the reciprocating operation is completed, the cleaning mechanism operation completion presence / absence storage unit 23 is not allowed to store the cleaning mechanism operation completion presence signal. .

  Further, when one reciprocating operation of the suction nozzle 13 of the cleaning mechanism 25 has already been completed, the cleaning mechanism operation completion presence / absence storage unit 23 stores that the cleaning mechanism operation completion presence signal has already been completed. (Y in Step 32) After the start of operation (Step 31), the operation of the multi-function device is started as usual (Step 35).

As described above, in the present embodiment, the operation start determination unit 21 that determines the start of operation, the cleaning mechanism operation completion determination unit 22 that determines whether the operation of the suction nozzle 13 of the cleaning mechanism 25 is completed, The cleaning mechanism 25 is operated once by the output from the cleaning mechanism operation completion presence / absence storage means 23 for storing whether or not the operation of the cleaning mechanism 25 is completed by the output from the cleaning mechanism operation completion determination means 22. If the air filter 11 is not operating, it is a control for operating the cleaning mechanism 25 at the start of operation of the multi-function device. At times, before operating the multi-function device, the suction nozzle 13 was driven back and forth to check whether the air filter 11 was installed correctly. Find the mounting deficiencies of the air filter 11 during're, early can respond defect, convenience is improved resulting user.

  Although not shown in particular, a cleaning mechanism operation completion presence / absence storage erasure unit for erasing information stored in the cleaning mechanism operation completion presence / absence storage unit 23 is provided, and the mounting state of the air filter 11 is confirmed in the assembly process of the multi-function device. Even when the cleaning mechanism 25 is operated, the cleaning mechanism operation completion presence / absence storage erasure unit erases the information indicating that the cleaning mechanism operation completion is stored in the cleaning mechanism operation completion presence / absence storage unit 23 before shipment from the factory. Then, the cleaning mechanism 25 can be reliably driven while there is a contractor in the market.

  In addition, when the cleaning mechanism control method described in the first embodiment is used for an air conditioner (not shown), even if there is a problem in the installation of the air filter during installation, Since it is improved while you are, there is no need for the user to reattach the air filter of the air conditioner installed at a high place later, providing an easy-to-use air conditioner It can be done.

  As described above, the cleaning mechanism control method of the multi-function device of the present invention is excellent in convenience because it can find and deal with an air filter installation failure while a multi-function device is installed while a contractor is present. Therefore, it can be widely applied to various multifunctional devices such as an air conditioner and an air purifier equipped with an air filter.
