Cooling operation to the valve Run with any of the heating. The indoor heat exchanger 412 is divided into a front side heat exchanger 412a and a rear side heat exchanger 412b. The front side heat exchanger 412a and the rear side heat exchanger 412b are connected via a concentrating mechanism composed of a dry bidirectional valve 415 and a capillary tube 416. When the dry two-way valve 415 is fully open, the air-cooling operation or the heating operation is performed, the dry two-way valve 415 is in a closed state, and the expansion valve 406 is fully open or substantially fully open, so that the front side heat exchanger 412a is a condenser, and the rear side The heat exchanger 412b is an evaporator, so that a so-called dehumidification operation can be performed. Further, the outdoor unit 402 and the indoor unit 403 are each provided with an outdoor control unit 420 electrically connected to the indoor control unit 42 and the two control units 42A and 421, and controls various operations of the air conditioner 401. The operation and action of the air conditioner having the above configuration will be described below. Fig. 5 is a flow chart showing the automatic cleaning control of the air filter of the embodiment of the present invention. As shown in Fig. 5, first, step 5〇1 determines whether or not the accumulated time of the stop time of the air conditioner measured by the time measuring device provided in the indoor control unit 421 has elapsed for a predetermined time. If the determination is YES, it is judged. There is dust accumulation on the upper surface of the air filter, and only the upper surface of the air filter is automatically cleaned in step 5G2. On the other hand, when the determination in step 501 is NO, the process proceeds to step 503. In addition, the accumulation time of the stop time of the air conditioner described above is set to 'hypothetical suction device Η) 6 operation - air adjustment of the amount of dust that can be attracted at a time 1351497 The total time during the stop of the machine is set to, for example, 360 hours. In step 503, it is determined whether it is the first operation after the previous cleaning. If YES, the process proceeds to step 504. On the other hand, if NO, the process proceeds to step 505. In step 504, it is determined whether the accumulated time of the operation time of the air 5 adjusting machine measured by the time measuring device exceeds a predetermined time. If the determination is YES, then the automatic cleaning of the air filter is performed in step 506, and the other is performed. On the other hand, if NO, the process returns to step 504. Further, the amount of dust that can be sucked by the suction device 106 once is assumed to be the amount that adheres to the air filter after the air conditioner is operated for about 24 hours, but the dust adheres to the air filter when the air conditioner starts operating after the previous cleaning. The amount of attachment of the device is small, so the cumulative time of the operation time of the aforementioned air conditioner can be set to be twice as many as 48 hours for 24 hours. Further, in step 505, it is determined whether or not the accumulated time of the operation time of the air conditioner measured by the time measuring device exceeds a predetermined time. If the determination is 15 YES, the process proceeds to step 506, and if NO, the process returns to the step. 505. Further, when the operation other than the initial operation after the cleaning is considered, a certain amount of dust adheres to the air filter. Therefore, the cumulative time of the operation time of the air conditioner at this time is set to operate the virtual suction device 106. 20 The total time during the operation of the air conditioner to which the amount of dust that can be attracted is attached is set to, for example, 24 hours. As described above, in the first embodiment, during the stop of the air conditioner, the dust easily adheres to the upper surface of the air filter which is substantially horizontally extended, so that only the portion can be cleaned, the cleaning time can be shortened, and the unnecessary time can be reduced. 8 12 consumes electricity. In addition, since the air is automatically cleaned according to the accumulated operation time of the air conditioner, the cleaning operation can be performed more easily and efficiently. After the air conditioner is cleaned, the air conditioner will judge the work. The cumulative running time of the cleaning of the device is set to be longer than the time of the other, so that unnecessary cleaning can be suppressed as much as possible, and the noise or the power generated by the cleaning can be reduced, and the convenience can be improved. Embodiment 2 Fig. 6 is a flow chart showing the automatic cleaning control of the air filter of the embodiment 2 of the present invention. As shown in Fig. 6, in step 6.1, the dust detector 422 is used to detect the amount of dust floating in the second, and when the detected amount of dust is above a predetermined value, the lion 2 'other-side' is entered. When the predetermined value is not satisfied, then returning to step 602, when the amount of dust of the air towel is above a predetermined value, it is determined whether the cumulative time of the operation time of the emptying machine exceeds the predetermined time. If the determination is YES, then Step 6〇3 Implement the automatic sweep of the air filter. If NO, return to step 6〇1. In addition, the predetermined time of the so-called dust amount refers to a state in which the amount of dust in the living space required for the experiment is large, for example, the state of the melon 2/3 is more than one, and the cumulative operation of the aforementioned air conditioner The predetermined time of the time is also assumed to be 'in the state where the air conditioner is in the state where the lcm2/s is 10 or more, and the dust is attached to the air passing device, and the suction device 103 operates once to attract the dust. Total time, for example about 12 hours. As described above, in the second embodiment, by detecting the amount of dust in the two gases around the air conditioner, the adhesion of the dust to the air filter 1351497 can be more accurately detected, and the air filter can be performed at an appropriate timing. The automatic cleaning of the device prevents unnecessary cleaning and improves convenience.
