- Patent Document 1 International Publication No. 2004Z053398 Pamphlet
- the drain water discharged from the drain pump includes not only large and small general waste, but also copper powder, which is the cutting powder of copper pipes used as piping, and seal tape used for pipe connections. Tape waste and textile waste generated from textiles such as clothes are included.
- these wastes are discharged together with the drain water even if the waste tends to remain, for example, even if the trap is in the drain pipe.
- the flow rate of drain water in the drain pipe becomes slow, for example, dust may remain in the trap and develop into clogging.
- this kind of clogging with a large drain pipe diameter has not been a problem.
- An object of the present invention is to avoid drainage clogging in the drain pipe by controlling the drain pump in a drain water draining system in which drain water is pumped by a drain pump.

- the heat exchanger 5 arranged so as to be attached is housed. Below the heat exchanger 5, there is a drain pan 6 that receives drain water dripping from the heat exchanger 5!
- a drain storage part 7 that stores drain water is formed in a part of the drain pan 6.
- a drain pump 10 for pumping drain water from the drain storage section 7 is attached to the drain pan 6.
- the heat exchange 5 is shown on the left and right sides of the blower 4.
- the drain pump 10 is generally used, and is a centrifugal pump whose discharge capacity automatically changes depending on the level of drain water in the drain reservoir 7.
- the drain pump 10 includes a main body housing and a housing 12 that house the rotating blades 11, a DC motor 13 that drives the blades, and a suction port 14 formed at a lower portion of the main body housing 12. And a discharge port 15 for discharging the drained water.
- the drain pump 10 having such a configuration sucks up drain water from the suction port 14 with the centrifugal force generated by the rotation of the rotary blade 11 and discharges the drain water from the discharge port 15.
- a drain pipe 16 led out of the machine is connected to the discharge port 15 of the drain pump 10.
- the discharge amount of the drain pump 10 increases as the water level in the drain storage section 7 increases, and decreases as the water level in the drain storage section 7 decreases.
- a water level sensor 20 is installed in the drain reservoir 7.
- the water level sensor 20 includes a float 21 that rises or falls according to a change in the water level of the drain water, and a support cylinder 22 that supports the float 21.
- the operation signal of each contact is transmitted to the control unit 25.
- the lower water level A is set at a position where the discharge rate of the drain pump 10 decreases and the flow rate of the drain water in the drain pipe 16 cannot be maintained at a predetermined value or higher when the water level drops below that level.
- the upper water level B is set to a position where the drain storage section 7 becomes full when the drain pump 10 is left without being operated.
- the control unit 25 controls the entire air conditioner and is based on input information from the water level sensor 20. Next, the operation of the drain pump 10 is controlled as shown in the mouth-chart shown in FIG. Hereinafter, the operation of the air conditioner and the operation control of the drain pump 10 will be described with reference to FIG.
- the air in the air-conditioning room R is taken into the main body 1 from the inlet 2a by the blower 4, and cooled or dehumidified by heat exchange ⁇ 5. .
- drain water is generated by heat exchange ⁇ 5.
- This drain water is received by the drain pan 6 and stored in the drain reservoir 7.
- the drain pump 10 is not operated until the water level in the drain reservoir 7 reaches the upper water level B (step Sl).
- the drain pump 10 is operated at the standard rotation speed (step S2).
- step S3 it is determined whether or not the rotational torque of the DC motor 13 is equal to or less than a predetermined value (step S3), and the residual state of dust in the drain pipe 16 is determined based on this.
- the rotational torque of the DC motor 13 may be measured by an appropriate method, directly or indirectly.
- the rotational torque of the DC motor 13 may be indirectly measured from the current value of the DC motor 13.
- step S6 If the rotational torque of the DC motor 13 is less than the predetermined value, the operation is continued as it is. If it is confirmed that the water level in the drain reservoir 7 is below the lower water level A (step S6), the drain water flow rate in the drain pipe 16 will drop below the specified value, and dirt will likely remain. The operation of the pump 10 is stopped (step S7).
- step S3 When it is determined that the rotational torque of the DC motor 13 exceeds a predetermined value (step S3), the rotational torque of the DC motor 13 is caused by the fact that dust exceeding a predetermined amount remains in the drain pipe 16. Is considered to have risen. Therefore, by increasing the discharge amount of the drain pump 10 and increasing the flow rate of the drain water in the drain pipe 16, the remaining waste is washed away at once.
- the drain pump 10 is operated in a state where the rotational speed of the drain pump 10 has increased by a predetermined value for a predetermined time (step S4), and after a predetermined time has elapsed, the rotational speed of the drain pump 10 is returned to the standard rotational speed. (Step S5).
- step S6 the operation of the drain pump 10 is stopped as described above (step S7). Thereafter, control is performed while this procedure is repeated. Therefore, drain If it is determined that the rotational torque of the DC motor 13 is large after the rotational speed of the pump 10 has increased for a predetermined time and then shifted to the standard rotational speed, the rotational speed of the drain pump 10 is increased again for the predetermined time. Control is performed as follows.
- the rotational speed of the drain pump 10 increases for a predetermined time. Since the waste is washed away at once, the clogging of the drain pipe 16 can be prevented.
- the start / stop control of the drain pump 10 is performed based on the level of the drain water in the drain reservoir 7 pumped up by the drain pump 10, the operation when the amount of water discharged from the drain pump 10 is small can be reduced. it can. Thereby, the residue of the dust in the drain pipe 16 can be further suppressed.
- the control of the drain pump 10 is different from the first embodiment. That is, at the beginning of the operation of the air conditioner, the drain water level in the drain reservoir 7 is usually low. Therefore, when the drain pump 10 is operated at the beginning of the operation of the air conditioner, the discharge amount of the drain pump 10 decreases. Dust collected in the drain pan 6 and the like is sucked into the drain pump 10 together with the drain water and flows into the drain pipe 16. As a result, the residual of dust in the drain pipe 16 is promoted, and thus the above control is not preferable.

Then, after a predetermined time has elapsed, the drain pump 10 is operated (step S13). Thereafter, the drain pump 10 is controlled while repeating this procedure.
- the control of the drain pump 10 is different from the first embodiment. That is, in the third embodiment, the discharge amount of the drain pump 10 is increased by operating the drain pump 10 at a predetermined cycle using a timer.
- the water level sensor 20 according to the first embodiment is omitted, and the other members are denoted by the same reference numerals and the description thereof is omitted.
- step S21 When the operation of the air conditioner is started, the operation control of the drain pump 10 is started.
- the timer is first reset (step S21). Subsequently, it is determined by the timer whether the force has passed the predetermined time T1 (step S22). Then, after a predetermined time T1 has elapsed, the drain pump 10 is operated (step S23). In addition, the timer determines whether or not the operation time of the drain pump 10 has passed the predetermined time T2 (step S24), and when the operation time of the drain pump 10 has passed the predetermined time T2, the operation of the drain pump 10 is stopped. (Step S25). Thereafter, the drain pump 10 is operated at a predetermined cycle by performing control while repeating this procedure.
- the drain pump 10 is operated when the water level of the drain storage unit 7 is high by appropriately setting the operation cycle of the drain pump 10, and the drain storage unit When the water level of 7 is low, the drain pump 10 can be set not to operate. By setting the operation cycle of the drain pump 10 in this way, it is possible to suppress the residue of dust in the drain pipe 16.
