other Embodiment approach

[0067] (Other Embodiments) The above-described embodiments may also be configured as follows.

[0068] In the described embodiment, a positive voltage is applied to the nozzle electrode 44, and the annular electrode 45 is grounded. However, it is also possible to apply a negative voltage to the nozzle electrode 44 and ground the ring electrode 45 . At this time, the negatively charged condensed water is sprayed from the nozzle electrode 44 in the form of a mist. In addition, since the same negative voltage as that of the nozzle electrode 44 is applied to the inflow pipe 51 at this time, the condensed water can be prevented from adhering to the inner wall of the inflow pipe 51 . Also, a potential difference may be applied between the nozzle electrode 44 and the ring electrode 45 by applying a positive voltage to the nozzle electrode 44 and a negative voltage to the ring electrode 45, for example; other configurations may also be used. A potential difference is applied to the ...

Abstract

The invention discloses a liquid feed device and air conditioning device. A drain pan (30) is connected to a nozzle electrode (44) and its other end opens upward. A ring electrode (45) is arranged so as to oppose to the nozzle electrode (44). When positive voltage is applied to the nozzle electrode (44), an electric field is formed in the vicinity of the tip end of the nozzle electrode (44). As aresult, drain water is sprayed as micro liquid droplets charged with positive charge. The sprayed liquid droplets are discharged to an outer system via a flow-in pipe (51) and a flow-out pipe (53).

Description

technical field [0001] The present invention relates to a liquid conveying device for conveying liquid in a storage container and an air conditioner provided with the liquid conveying device. Background technique [0002] Heretofore, liquid transport devices for transporting liquids have been used in a wide range of fields. As such a liquid transfer device, Patent Document 1 discloses a drain pump for draining drain water in an air-conditioning device that adjusts indoor air. [0003] The air conditioner in Patent Document 1 includes a so-called ceiling-mounted indoor unit. Inside the casing of the indoor unit are housed an indoor heat exchanger through which air circulates, a drain pan (storage container) formed on the lower side of the indoor heat exchanger, and a drain pan provided in the drain pan. Pumps (liquid handling devices). [0004] During cooling operation of the air conditioner, indoor air is sucked into the cabinet and passes through the indoor heat exchange...
