Therefore, for example, by operating the filter cleaning unit in a state where the operation of heating or cooling is stopped, more specifically, by rotating the cleaning brush 37 while moving the filters 35 and 36, Dust adhering to the filters 35 and 36 can be appropriately removed by the cooling operation, so that heating or cooling can be performed efficiently and indoor air can be ventilated.

  Below, the structure of the control system of the air conditioner 1 which concerns on this embodiment is demonstrated. FIG. 2 is a block diagram showing a configuration example of a main part of a control system of the air conditioner 1 according to the present invention. The air conditioner 1 includes a CPU 11 having a built-in ROM and RAM, an air-conditioning unit 12 that performs a cooling operation or a heating operation by exchanging heat between outdoor air and indoor air with the configuration shown in FIG. The filter cleaning unit 14 and the signal receiving unit 15 described above are provided, and are connected to each other via the bus 10. In addition, each part of such hardware operate | moves with the electric power supplied from the power supply device which is not shown in figure.

  The CPU (control means) 11 is a main control unit of the air conditioner 1 and controls the above-described hardware units connected via the bus 10 and is stored in advance in a ROM built therein. The appropriate control program is read into the RAM as appropriate and executed. In the ROM, various control programs necessary for operating the air conditioner 1 as the air conditioner according to the present invention are stored in advance. The RAM is composed of SRAM, flash memory, or the like, and temporarily stores data generated when the CPU 11 executes the control program.

  The signal accepting unit 15 accepts various control signals issued from the remote controller 1 a and sends the accepted control signals to the CPU 11. The CPU 11 appropriately executes a control program stored in the ROM based on the control signal sent from the signal receiving unit 15. The remote controller 1a is provided with operation buttons for the user to perform instructions such as selection of cooling operation or heating operation, setting of target temperature, change of wind direction, execution of ventilation function, execution of filter cleaning function, etc. In response to the operation button operated by the above, an operation instruction signal for instructing the operation of each part of the hardware provided in the air conditioner 1 is transmitted.

  The filter cleaning unit 14 includes a filter detection unit 16 and a filter drive unit 17 in addition to the ventilation unit 13, the cleaning brush 37, the filters 35 and 36, and the like described above. The filter detection unit (detection unit) 16 is a sensor that detects whether or not the filters 35 and 36 are attached. Accordingly, the filter detection unit 16 has changed from the state in which the filters 35 and 36 have been removed to the state in which the filters 35 and 36 have been removed, for example, when the filters 35 and 36 that have been removed for cleaning by the user are attached again. Is detected.

  When the filter detection unit 16 detects the attachment of the filters 35 and 36, the filter drive unit (moving unit) 17 moves the filters 35 and 36 to a predetermined initial position according to control by the CPU 11. As a result, the filters 35 and 36 that have been once removed and reattached can be set to appropriate initial positions. The filter driving unit 17 is not limited to the case where the filters 35 and 36 are mounted, and appropriately moves the filters 35 and 36 relative to the cleaning brush 37 during the normal filter cleaning operation performed by the air conditioner 1. .

  Here, this embodiment demonstrates the case where the air conditioner 1 which concerns on this invention is used after removing the air conditioner which does not have a ventilation function. Specifically, the air conditioner 1 having a ventilation function needs to pass not only the refrigerant pipe but also the ventilation hose through the pipe 2a as described above. The case where the ventilation hose cannot be taken out through the piping hole 100a when installing the air conditioner 1 having a ventilation function because the piping hole 100a provided at the time of installation will be described.

  When the ventilation unit 13 is operated in the air conditioner 1 in such a state that the ventilation hose cannot be taken out in this way, the indoor user feels uncomfortable because the air to be discharged outside is not discharged. There is a fear. Since the situation in which the ventilation function cannot be appropriately used in this way is apparent when the air conditioner 1 is installed, the service person or user who installed the air conditioner 1 has the ventilation function after the air conditioner 1 is installed. It is necessary to set prohibition of operation. Therefore, the remote control 1a of the present embodiment is provided with a ventilation prohibition button for the user to instruct prohibition of the operation of the ventilation function.

  When the service person or the user operates the ventilation prohibition button of the remote controller 1a, the remote controller 1a sends a corresponding control signal, specifically, a prohibition instruction signal instructing prohibition of the operation of the ventilation unit 13 to the signal receiving unit 15. To do. When receiving the prohibition instruction signal from the remote controller 1a, the signal receiving unit 15 sends the received prohibition instruction signal to the CPU 11. The CPU 11 is provided with a ventilation prohibition flag indicating prohibition of the operation of the ventilation unit 13 in its own RAM, and when the prohibition instruction signal is acquired from the signal receiving unit 15, the CPU 11 turns on the ventilation prohibition flag.

  Therefore, the CPU 11 determines whether or not the ventilation prohibition flag is on when the user instructs execution of the ventilation function via the remote controller 1a, and operates the ventilation unit 13 only when it is off. Thereby, in the air conditioner 1 in a situation where the ventilation function cannot be appropriately used, even if the user mistakenly instructs the execution of the ventilation function, the operation of the ventilation unit 13 is surely prohibited, and the ventilation unit 13 Inappropriate operation can be prevented.

  Furthermore, when the filter cleaning unit 14 operates in the air conditioner 1 in a state where the ventilation function cannot be appropriately used, the dust scrubbed off from the filters 35 and 36 is not properly discharged to the outside and pollutes the indoor air. There is a fear. Therefore, the air conditioner 1 of the present invention is configured to prohibit the operation of the filter cleaning function when the operation of the ventilation function is prohibited. Specifically, the CPU 11 is further provided with a filter cleaning prohibition flag indicating that the operation of the filter cleaning unit 14 is prohibited in its own RAM. When the CPU 11 obtains a prohibition instruction signal from the signal receiving unit 15, the filter is combined with the ventilation prohibition flag. Turn on the cleaning prohibition flag.

  Therefore, the CPU 11 determines whether or not the filter cleaning prohibition flag is on when the user instructs the execution of the filter cleaning function via the remote controller 1a, and operates the filter cleaning unit 14 only when it is off. . As a result, in the air conditioner 1 in a situation where the ventilation function cannot be properly used, even when the user mistakenly instructs the execution of the filter cleaning function, the operation of the filter cleaning unit 14 is surely prohibited, and the filter cleaning is performed. Inappropriate operation of the unit 14 can be prevented. It should be noted that the service person or the user only has to indicate that the ventilation function is prohibited, and the operation burden can be reduced.

  Further, in the air conditioner 1 of the present embodiment, when the removed filters 35 and 36 are attached to predetermined positions, the filters 35 and 36 are moved by the filter driving unit 17 and set to appropriate positions. It is configured. Accordingly, when the filter detection unit 16 detects the attachment of the filters 35 and 36, the CPU 11 determines whether or not the filter cleaning prohibition flag is on, and operates the filter cleaning unit 14 only when it is off. When the filter cleaning prohibition flag is on, the CPU 11 controls only the filter driving unit 17 to move the filters 35 and 36 to a predetermined initial position. As a result, when the operations of the ventilation unit 13 and the filter cleaning unit 14 are prohibited, the filters 35 and 36 that have been once removed and reattached are appropriately prevented while preventing an inappropriate operation of the filter cleaning function. It can be set to the initial position.

  Below, in the air conditioner 1 of this embodiment, the setting process for prohibiting operation | movement of a ventilation function is demonstrated. FIG. 3 is a flowchart showing a processing procedure for setting the prohibition of the operation of the ventilation function in the air conditioner 1 according to the present invention. The following processing is executed by the CPU 11 in accordance with a control program stored in a ROM built in the CPU 11.

  The service person who installed the air conditioner 1 according to the present invention determines whether or not the ventilation function in the air conditioner 1 can be used based on the installation status of the air conditioner 1. When the air conditioner 1 after the installation of 1 is not in operation, the ventilation prohibition button of the remote control 1a is operated.

  The CPU 11 determines whether or not the control signal issued from the remote controller 1a has been received via the signal receiving unit 15 (S1), and if it determines that the control signal has not been received (S1: NO), the control signal Wait until you accept. When it is determined that the control signal issued from the remote controller 1a has been received (S1: YES), the CPU 11 determines whether a prohibition instruction signal for instructing prohibition of the ventilation function is received (S2). When the CPU 11 determines that the prohibition instruction signal has not been received (S2: NO), the CPU 11 executes normal processing in normal operation in response to the received control signal (S4). When the CPU 11 determines that the prohibition instruction signal has been received (S2: YES), it turns on both the ventilation prohibition flag and the filter cleaning prohibition flag provided in its own RAM (S3).
