改良を加えたものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a drain device for an air conditioner, such as a ceiling-mounted air conditioner, and particularly improves the drive method of the drain pump.

さにボンプア ・ツブされる。(Prior art) For example, in a ceiling-mounted air conditioner that is used by being embedded in the ceiling or suspended from the ceiling, drain water is discharged outdoors through a drain channel installed in the ceiling. . Then, in order to provide an appropriate drain slope to the drain waterway in the ceiling, the drain water is pumped to a predetermined water head height using a drain pump.

を一気に排出するようにしている。Conventionally, a rotary pump is generally used as this type of drain pump. For example, Utility Model Publication No. 51-26923
The centrifugal drain pump disclosed in the publication is one of the typical rotary pumps. All pumps of this type are driven by a motor, and are activated only when necessary to intensively discharge drain water. In other words, the drain water generator is very small compared to the pump's drainage capacity, so the drain water is stored to a certain extent, and when the water reaches a certain level, the drain pump is activated and the drain water is discharged all at once. I try to do that.

点でも問題があった。(Problems to be Solved by the Invention) In the conventional drain device as described above, the drain pump operates intermittently with relatively long pauses, so the operating noise is more strongly affected by the actual sound pressure level. was often taken away and was jarring. In addition, since drain water accumulates even after the heat exchange function is stopped, control is complicated, as it is necessary to control the operation of the pump separately from the operation control of the air conditioner itself. In addition to these, since the load on the motor is relatively large and rush current is likely to act upon startup, there are other problems such as short life of the motor, premature generation of noise, and high power consumption.

Perform discharge. Specifically, as shown in Fig. 1, for example, a reciprocating pump (15) with a bellows (18) as a pump element is provided, and this is made of a shape memory alloy so that it expands and contracts in response to changes in am. A formed operating member (16), for example a coil spring-like operating member (16), is used to reciprocate. This operating member (16) is connected to a flow path (10) through which drain water generated in the air conditioner flows.
), and is cooled by the drain water passing through the flow path (10) and is elongated and deformed, for example. Further, a heater (24) is provided to heat the operating member (16),
For example, the operating member (16) contracts and deforms due to heating by the heater (24). A control switch (25) is provided to control power supply to the heater (24).

0) into the case (14), and as shown in FIG. 3, the operating member (16) is cooled while falling from the water hole (22) to the inner bottom of the case (14). The drain water temperature is about 10° C. on average, and the operating member (16) can be sufficiently stretched and deformed. As the operating member (16) expands and deforms, the cap (21) is activated by the auxiliary spring (17).
The bellows (18) moves upward against the

続ける。When the operating member (16) extends to near the low temperature deformation limit, the cap (21) pushes up the operating piece (25a) and turns on the control switch (25) (at this point, the suction valve (19a) (falls down and closes the valve)
. When the 1bIJ control switch (25) is turned on, current flows to the heater (24) via the control circuit (26) and generates heat. When the operation member (16) is heated beyond a certain m mark by the heat generated by the heater (24), it rapidly contracts and deforms as shown in FIG. 17) is pushed downward to turn off the control switch (25). At the same time, the bellows (18) is contracted, so the drain water sucked into the pump chamber (18a) inside the bellows (18) is discharged from the discharge boat (2).
Push open the discharge valve (20a) of 0) and open the discharge passage (12).
is fed under pressure to the drain hose (11). Thereafter, when the heating of the heater (24) is stopped by turning off the control switch (25), the operation member (16) removes the drain water accumulated in the case <1;+> and the drain pan (8). It is cooled again by the drain water flowing down from the pipe and begins to stretch and deform. Thereafter, as the operating member (16) repeats expansion and contraction deformation, the pump (15)
is driven back and forth with a gentle cycle and continues to discharge drain water.
