The specific embodiment
(example 1)
With reference to Fig. 1～Fig. 3 the air conditioner of each example 1 of the present invention is described.
In example 1, the present invention is applied in the ceiling-mounted-in type air conditioner as one of air conditioner installed at high place.The ceiling-mounted-in type air conditioner of this example 1 is the indoor unit of separate type air conditioner, comprising: the installing panel 2 of taking in the body 1 of various device in inside and being configured in body 1 bottom.The peristome 3a that body 1 is formed by the ceiling 3 of the R from the air conditioning chamber inserts the ceiling back side and is installed on the ceiling 3.Installing panel 2 embeds the peristome 3a of said ceiling 3, be installed in ceiling closely with the R of air conditioning chamber facing surfaces on.Central portion at this installing panel 2 is formed with the suction inlet 2a that sucks the air in the air conditioning chamber.On installing panel 2, be formed with cooling at four positions of the periphery that surrounds suction inlet 2a but or the air outlet 2b that blows out of air after the dehumidifying.
In body 1, take in: the air in the air conditioning chamber is sucked in the body 1 and with its pressure fan 4 that blows out to peripheral direction and the heat exchanger 5 that disposes with the form that surrounds pressure fan 4 peripheries via the suction inlet 2a that is located at installing panel 2 central portions.Below heat exchanger 5, dispose drip tray 6, this drip tray 6 is undertaken on the condensed water that produces and drip in the heat exchanger 5.On the part of drip tray 6, be formed with the condensed water reservoir 7 that stores condensed water.On drip tray 6, be equipped with from the draining pump 10 of condensed water reservoir 7 suction condensed waters.In Fig. 1, show heat exchanger 5 be configured in respectively pressure fan 4 about, but when heat exchanger 5 is seen in the top, said about the heat exchanger 5 of configuration be integral continuously.Likewise, in Fig. 1, show drip tray 6 also with about the form configuration that separates, but when drip tray 6 is seen in the top, said about the drip tray 6 of configuration be integral continuously.
Draining pump 10 is centrifugal pumps normally used, change the discharge capacity automatically according to the water level of the condensed water in the condensed water reservoir 7.As shown in Figure 2, draining pump 10 comprises: the outlet 15 that inside is taken in the body housing 12 of rotating vane 11, the dc motor 13 of driven vane, the suction inlet 14 that forms in the bottom of body housing 12 and will be aspirated the condensed water discharge that comes.Draining pump 10 with this structure utilizes the centrifugal force that is produced by rotating vane 11 rotations from suction inlet 14 suction condensed waters, and from outlet 15 condensed water is discharged.On the outlet 15 of draining pump 10, be connected with the condensed water tubing 16 that is exported to outside the air conditioner.The discharge rate of this draining pump 10 increases along with the rising of condensed water reservoir 7 water levels, and reduces along with the reduction of condensed water reservoir 7 water levels.
As shown in Figure 2, be provided with level sensor 20 in condensed water reservoir 7.Level sensor 20 comprises: float 21 that rises or descend according to the SEA LEVEL VARIATION of condensed water and the support tube 22 that supports float 21.First contact of moving when in the support tube 22 of level sensor 20, taking in below float 21 is positioned at water level A and second contact of above float 21 is positioned at, moving during water level B.The actuating signal of each contact is sent to control part 25.Below water level A be set at when water level drop to its when following the discharge rate of draining pump 10 reduce, can't the flow velocity of the condensed water in the condensed water tubing 16 be held in the position more than the setting.Condensed water reservoir 7 became the position of full state when top water level B was set at the state that does not move when draining pump 10 maintenances.
25 pairs of air conditioner integral body of control part are controlled, and based on the input information from level sensor 20, the flow chart that kind shown in the image pattern 3 is controlled the operation of draining pump 10.With reference to Fig. 3 the run action of air conditioner and the operation control of draining pump 10 are described below.
Carry out refrigerating operaton or when operation dehumidifying at air conditioner, the air in the R of air conditioning chamber is sucked in the body 1 from suction inlet 2a by pressure fan 4, and in heat exchanger 5, cools off or dehumidify.At this moment, in heat exchanger 5, generate condensed water.This condensed water is accepted and is accumulated in condensed water reservoir 7 by drip tray 6.Draining pump 10 does not move (step S1) before the water level B above the water level of condensed water reservoir 7 arrives.During water level B, draining pump 10 is with rated rotational frequency operation (step S2) above the water level of condensed water reservoir 7 arrives.
When air conditioner was used for a long time, rubbish remained in the turn of bilge (not shown) of condensed water tubing 16 easily.If residual ormal weight rubbish in condensed water tubing 16, then the torque meeting of draining pump 10 is risen, and the torque of dc motor 13 is risen.Therefore, whether the torque to dc motor 13 is to judge (step S3) below the setting in the present invention, judges the residual situation of rubbish in the condensed water tubing 16 thus.In this case, the torque of dc motor 13 can be measured through direct or indirect proper method.For example, the current value of dc motor 13 also capable of using measures indirectly the torque of dc motor 13.If the torque of dc motor 13 is below the setting, then continue operation with this state.If confirming the water level of condensed water reservoir 7 is (step S6) below the water level A of below, then the flow velocity of the condensed water in the condensed water tubing 16 can drop to below the setting, and rubbish is residual easily, therefore, the operation of draining pump 10 is stopped (step S7).
Surpass setting (step S3) if be judged as the torque of dc motor 13, then think to have caused the torque of dc motor 13 to be risen because of the residual rubbish that surpasses ormal weight in the condensed water tubing 16.Therefore, improve the flow velocity of the condensed water of condensed water tubing 16, the rubbish under residual is washed away quickly through the discharge rate that increases draining pump 10.Therefore, make draining pump 10 increase operation (step S4) under the state of setting with the stipulated time at the rotating speed of draining pump 10, after having passed through the stipulated time, make the rotating speed of draining pump 10 get back to rated rotational frequency (step S5).Afterwards, if the water level of condensed water reservoir 7 drops to below the setting (step S6), then the operation of draining pump 10 is stopped (step S7).Then, Yi Bian Yi Bian carry out this order repeatedly and control.Therefore, big as if the torque that is judged as dc motor 13 when the rotating speed of draining pump 10 has transitted to rated rotational frequency after rising with the stipulated time, then control once more, so that the rotating speed of draining pump 10 increased with the stipulated time.
Adopt the air conditioner of this example of said structure, residual when surpassing the rubbish of ormal weight in condensed water tubing 16, increase the rotating speed of draining pump 10 with the stipulated time, rubbish is washed away quickly, therefore, can prevent rubbish in condensed water tubing 16, to stop up.In addition, owing to stop control, therefore can reduce operation in the water yield of discharging from draining pump 10 according to the startup of being carried out draining pump 10 by the water level of the condensed water of draining pump 10 suctions, condensed water reservoir 7 after a little while.Thus, it is residual in condensed water tubing 16 further to suppress rubbish.
(example 2)
The difference of example 2 and example 1 is the control of draining pump 10.That is, when air conditioner just moved, the water level of the condensed water of condensed water reservoir 7 was lower usually.Therefore, if when air conditioner just moves, make draining pump 10 operations, then the discharge rate of draining pump 10 can reduce.In addition, the rubbish that accumulates in drip tray 6 can flow by draining pump 10 attractions and to condensed water tubing 16 with condensed water.Consequently, can promote rubbish residual in condensed water tubing 16, therefore, the control of above-mentioned that kind is unsatisfactory.In example 2, only omitted the level sensor 20 of example 1, to the identical symbol of other parts mark and omit its explanation.
In example 2, the flow chart that kind shown in the image pattern 4 is controlled the operation of draining pump 10.When the operation of air conditioner begins, the operation control of beginning draining pump 10.In operation when control of beginning draining pump 10, at first make timer reset (step S11).Then, utilize timer to judge whether to have passed through certain hour (step S12).Then, after having passed through certain hour, make draining pump 10 operations (step S13).Then, Yi Bian control draining pump 10 Yi Bian carry out this order repeatedly.
In the air conditioner of example 2, draining pump 10 does not move when the operation of the few air conditioner of the condensed water of condensed water reservoir 7 begins, and therefore, can reduce the chance that rubbish stops up in condensed water tubing 16.
(example 3)
The difference of example 3 and example 1 is the control of draining pump 10.That is, in example 3, utilize timer that draining pump 10 is moved with specified period, thereby increase the discharge rate of draining pump 10.In example 3, only omitted the level sensor 20 of example 1, to the identical symbol of other parts mark and omit its explanation.
In example 3, the flow chart that kind shown in the image pattern 5 is moved control.When the operation of air conditioner begins, the operation control of beginning draining pump 10.In operation when control of beginning draining pump 10, at first make timer reset (step S21).Then, utilize timer to judge whether to have passed through stipulated time T1 (step S22).Then, after having passed through stipulated time T1, make draining pump 10 operations (step S23).Then, utilize timer to judge and whether passed through stipulated time T2 (step S24) running time of draining pump 10,, the operation of draining pump 10 is stopped (step S25) if passed through stipulated time T2 the running time of draining pump 10.Then, and meanwhile carry out this order repeatedly and control, thus draining pump 10 is moved with specified period.
Adopt the air conditioner of example 3, make draining pump 10 operation and when the water level of condensed water reservoir 7 is low, not moving when the water level of condensed water reservoir 7 is high through the cycle of operation of draining pump 10 suitably being set, can being set for.Through the cycle of operation of such setting draining pump 10, it is residual in condensed water tubing 16 to suppress rubbish.
In above-mentioned each example, preferably the parts that contacts with condensed water such as drip tray 6, draining pump 10, condensed water tubing 16 are with anti-biotic material, for example comprise the antibacterial metal material formation such as resin material or copper pipe of antiseptic.If use this material in the present invention, then can will remain in the Overlay that the rubbish in the condensed water tubing 16 washes away based on the bactericidal effect of antiseptic and through the flow velocity of accelerating draining pump 10, more effectively avoid rubbish in condensed water tubing 16, to stop up.
