The outdoor unit includes a four-way valve 12 and the compressor 13 constituting the refrigerating cycle, the outdoor fan 1 4.
[0012]
Setting control circuit 1 of the indoor unit side, the opening and closing panel 3 a in accordance with the setting operation of the remote control 9, 3b, short circuit panel 3 c, while controlling the vertical airflow direction plate 4 Contact and indoor fan 6, room temperature The operation code of the compressor corresponding to the temperature difference is transmitted to the control circuit 2 on the outdoor unit side, and signals necessary for the room temperature control are exchanged with the control circuit 2. Further, the electric dust collector 7 is controlled in accordance with the setting operation of the remote controller 9 or the like.
[0013]
Therefore, the control circuit 1 on the indoor unit side includes a determination unit 1a that determines a remote control signal, a state determination unit 1c that determines the operating state of the air conditioner, and a timer unit that is used when executing the routines shown in FIGS. 1b, a storage unit 1d, a counter unit 1e, and a humidity detection determination unit 1f. Further, the control circuit 2 of the outdoor unit side, and the driving mode judging unit 2a for determining the operating mode or the like from the indoor unit side for controlling the four-way valve 12 and the outdoor fan 1 4, compression of controlling the compressor 13 The function of the machine control unit 2b is provided. The indoor unit and the outdoor unit are provided with parts (such as various sensors) necessary for the air conditioner, and the control circuits 1 and 2 perform room temperature control using the necessary parts and the parts described above.
[0014]
Next, the operation of the air conditioner configured as described above will be described with reference to the flowcharts of FIGS. 1 and 2. First, when a predetermined setting operation is performed by the remote controller 9, control necessary for the room temperature control is performed by the control circuit 1 on the indoor unit side and the control circuit 2 on the outdoor unit side in accordance with the setting operation. In this case, the control circuit 1, automatically opening and closing control switching panel 3 a, 3b, a short circuit panel 3 c and the horizontal flaps 4 according the operation mode etc. of the setting operation, rotation of the indoor fan 6 And the electric dust collector 7 is controlled.
[0015]
When the clean operation signal is transmitted by the remote controller 9 and the clean operation signal is received, the control circuit 1 executes the routine shown in FIG. In this routine, the indoor humidity R h is detected by the humidity detection determining unit 1f by the detection signal of the humidity sensor 8 (step ST1), the operation of the air conditioner whether it is heating or blowing in a state determination unit 1c Judgment is made (step ST2), and the operation state is stored in the storage unit 1d.
[0016]
If the operation is heating or air blowing, and starts a 3-minute timer of the timer unit 1b (step ST3), the switching the operation mode to the blower, the fan speed of the indoor fan 6 and the blower of the weakening and 900 rpm, open panel 3 a, as well as the fully opened state 3b, the short-circuit panel 3 c closed, as well as the horizontal flaps 4 in the horizontal direction, to clean displayed on the main display unit 10 (step ST4).
[0017]
By maintaining the air blowing operation (drying operation) for 3 minutes, the interior of the indoor unit can be dried. That is, because the previous operation is heating or air blowing, for example, the drain pan 11 does not collect condensed water. In addition, since an indoor fan is weak ventilation, indoor environment is not deteriorated. When the 3-minute timer times, the process proceeds from step ST5 to ST6, and stops the operation of the indoor fan 6, to stop the drying operation.
[0018]
Subsequently, opening and closing panel 3 a, as well as the fully closed 3b, the short-circuit panel 3 c the open state, and the vertical airflow direction plate 4 upward (step ST7), the timer of timer section 1b (e.g. T = 15 minutes) (step ST8), the electrostatic precipitator 7 is turned on (step ST9), ozone is generated by the electrostatic precipitator 7, and the ozone is not diffused indoors. Incidentally, the ON time of the electric dust collecting part 7 (the timer time; operating time) has been in advance empirically determined value (15 minutes), for example, a value set in advance according to the room humidity R h, humidity R It is ideal if the operating time is set to a longer value as h increases.
[0019]
Then, the indoor fan 6 is operated for 5 seconds (step ST10), for example, to spread throughout the interior of at least the indoor unit of ozone by the rotation speed 600 rpm. After operating the indoor fan 6 for 5 seconds, the operation is stopped for 1 minute (step ST11), ozone was stuck fall inside the indoor unit, deodorization, increase the sterilization effect. Subsequently, it is determined whether or not the 15-minute timer has expired (step ST12).
[0020]
Until the lapse of 15 minutes, step ST10 returns, the indoor fan 6 is operated for 5 seconds, after which the process is repeated to stop 1 minute operation of the indoor fan 6. Thus, by operating the indoor fan 6 intermittently, the electrical dust collecting unit 7 ozone generated by the indoor unit interior was efficiently spread, deodorization, it is possible to reliably sterilizing. After the deodorization and sterilization operation inside the indoor unit, the operation of the air conditioner is returned to the operation state (the state before the clean operation) stored in the storage unit 1d (step ST13), the routine Exit.
[0021]
By the way, when the clean operation signal transmission operation is performed by the remote controller 9, when the air conditioner is in an operation other than the heating operation or the air blowing operation (for example, including cooling, drying, and operation stop), step ST2 is performed. To ST14, the constants of the heating 0 code transmission count value K and the operation time (timer time T) of the electric dust collector 7 are determined. As described above, the operating state is determined by the state determination unit 1c and stored in the storage unit 1d. In the process of step ST14, the indoor unit the drying, deodorizing, in order to perform a sterilization effectively, the higher the indoor humidity R h, and the value K to a larger value, to determine a timer time T to a long value.
[0022]
When the indoor humidity Rh is as high as 80% or higher, the process proceeds from step ST15 to ST16, where the humidity detection determination unit 1f sets the heating 0 code transmission count value K to 4, and the timer time T is determined to be 20 minutes. When the indoor humidity Rh is 60% or more and lower than 80%, the process proceeds to step ST18 via steps ST15 and ST17, the heating 0 code transmission count value K is set to 3, and the timer time T is determined to be 15 minutes. When the indoor humidity Rh is lower than 60%, the process proceeds to ST19 via steps ST15 and ST17, the heating 0 code transmission count value K is set to 2, and the timer time T is determined to be 10 minutes.
[0023]
Then, to start the 3 minute timer of the timer unit 1b (step ST20), switching the operation mode to the heating, transmits the operation code 0 of the compressor 13 (the rotational speed 0Rps), fan speed of the indoor fan 6 was a blast of weakening and 900 rpm, the clean-off panel 3 a, with a fully open 3b, the short-circuit panel 3 c closed, as well as the horizontal flaps 4 in the horizontal direction, the main body display section 10 Display is performed (step ST21). In this case, on the outdoor unit side, the heating mode is determined by the operation mode determination unit 2a, the four-way valve 12 is switched, and the refrigeration cycle is switched.
[0024]
When the 3-minute timer expires, the process proceeds from step ST22 to ST23, and the heating 0 code transmission counter of the counter unit 1e is incremented. Here, since it is the first heating 0 code transmission, the heating 0 code transmission counter is 1. Subsequently, it is determined whether or not the value of the heating 0 code transmission counter is the determined value K (step ST24). If the counter value is not K, the 2-minute timer of the timer unit 1b is started (step ST24). ST25).
[0025]
Then, the operation mode and heating, the operation code of the compressor 13 and 8 (rpm 39Rps), the fan speed of the indoor fan 6 and 900 rpm (Step ST26). In this case, on the outdoor unit side, the heating mode is determined by the operation mode determination unit 2a and the four-way valve 12 is switched, and the compressor control unit 2b controls the compressor 13 to a rotational speed of 39 rps. It controls the rotation of the outdoor fan 1 4 with the.
[0026]
It is determined whether or not the two-minute timer has expired (step ST27), and when the time is up, the process returns to step ST20 to repeat the above-described processing. Therefore, the operation of setting the air conditioner to the heating operation and setting the rotation speed of the compressor 13 to 0 rps for 3 minutes and then setting the rotation speed of the compressor 13 to 39 rps for 2 minutes is repeated K times. Thus, the higher the indoor humidity R h, since the heating 0 code originating count value K is determined largely, even high room humidity R h, drying operation time is prolonged, to sufficiently dry the inside of the indoor unit be able to. In addition, since the heating operation can be said to be weak heating, the indoor environment does not deteriorate.
[0027]
Subsequently, when the heating 0 code transmission counter value reaches the determined value K, the above-described drying process is terminated, the process returns from step ST24 to step ST6, and the above-described deodorization and sterilization processes in steps ST6 to ST12 are executed. Since the deodorizing and sterilizing treatment has already been described, the description thereof is omitted. In this case, the time T of the timer that starts in step ST8 is the value determined in step ST14.
[0028]
For example, when the indoor humidity Rh is as high as 80% or more, the deodorizing and sterilizing effects inside the indoor unit are inevitably weakened, so the ozone generation time by the electric dust collector 7 is lengthened (T = 20 minutes). On the contrary, when the indoor humidity Rh is lower than 60%, the deodorization and sterilization inside the indoor unit are sufficiently performed even if the ozone generation time is short (T = 10 minutes).
[0029]
As described above, in the case where the operation state before the clean operation transmission is other than the heating or the air blowing operation, even if the indoor humidity Rh is high, after the interior of the indoor unit is sufficiently dried, the ozone is spread inside the indoor unit, Deodorization and sterilization inside the machine can be performed effectively. Moreover, deterioration of the indoor environment can be suppressed, and when the indoor humidity Rh is low, the clean operation time can be shortened.
[0030]
Further, when the clean operation is performed, the fact is displayed on the main body display unit 10 to notify the user or the like, so that the convenience of the user or the like can be improved. Further, when the clean operation is completed, the operation of the air conditioner is automatically returned to the original operation state, so that it is not necessary for the user or the like to operate the remote controller 9 again. Can be improved.
[0031]
In the embodiment described above, the preset operating time (timer time T: 15 minutes, for example) of the electric dust collector 7 is used during the heating operation or the air blowing operation, but the indoor humidity is particularly high during the air blowing operation. In some cases, the heating 0 code transmission count value K and the time T may be determined, and the processing after step ST20 (drying operation, deodorization, sterilization operation) may be performed.
[0032]
