Abstract

PURPOSE:To obviate a drain hose by further uniting a drained water atomizing means with a reprocessing means based on a module system which sends back to the drained water atomizing means an unprocessed water remaining unatomized with the drained water atomization means for reprocessing and installing it separated from indoor equipment. CONSTITUTION:During cooling operation, an indoor heat exchanger 16 works as a vaporizer and a mist is produced due to the heat exchange with the indoor air. The produced mist is turned into drained water and drops on a mist receiving pan 17 and further drops spontaneously on a rotator 6 revolving at high speed by way of a hose 5a. The drained water is radially scattered in the circumferential direction of the rotator 6 and collided violently against a large number of projected parts 13 and turned into a mist and discharged out in an outdoor atmosphere from a mist blow-off port 12. The drained water liquefied again on the inner wall of a case 11 is collected as an unprocessed water 14 dropping spontaneously from an unprocessed water collection circuit 15 to a case 10 and then it is adapted to drop again on the rotator 6 with a pump 8 and turned into a mist and discharged into an ambient atmosphere from the moist blow-off port 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain water treatment device for a separation type air conditioner for treating drain water generated from an indoor unit during cooling of the separation air conditioner.

[0002]

2. Description of the Related Art In a conventional separation type air conditioner of this type, drain water is generally generated in the indoor heat exchanger during cooling, and this drain water is not necessary. It was common to discharge.

[0003]

If the drain water is to be discharged to the outside by the drain hose as described above, it is necessary to install the drain hose, and the installation work of the drain hose is relatively complicated. In addition, the drain hose has problems in terms of aesthetics and weather resistance.

[0004]

DISCLOSURE OF THE INVENTION The drain water treatment apparatus for a separation type air conditioner of the present invention solves the above problems, and guides the drain water formed from the indoor unit to rotate it during cooling. An indoor unit that integrates a unit for drain water atomization for spraying and atomizing by the body and a unit for guiding untreated water that could not be atomized by the drain water atomization unit to the rotating body again (unitized) It is configured to be installed separately from the outdoor unit and the outdoor unit.

[0005]

According to the present invention, the drain water generated from the indoor unit is dripped into the rotary atomizing means and atomized into the atmosphere on the outdoor side. Drainage work using a hose can be eliminated, and since a rotary atomizer is used, no nozzles, switching valves, vibrators, etc. are used at all, so clogging due to dust mixed in the drain water and drain water treatment capacity It can be configured so that it does not deteriorate, does not require regular cleaning, and can improve reliability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the drain water treatment apparatus for a separation type air conditioner of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are schematic explanatory views showing the mounting state of the atomizing unit of one embodiment of the drain water treatment apparatus of the separation type air conditioner of the present invention. In FIGS.
Is an outdoor unit of the separation type air conditioner, 2 is a piping pipe that connects the outdoor unit 1 and the indoor unit 4 to form a refrigeration cycle, and 3 is an atomizing unit.

FIGS. 3, 4 and 5 are a front sectional view, a right side sectional view and a plan view of the atomizing unit, and FIGS.
5, 5a is a drain hose that guides the drain water generated from the indoor unit 4 to the atomizing unit 3, 6 is a rotating body (rotary atomizer) that atomizes the drain water that is guided, and 7 is the rotary 6
A motor for giving rotation to the rotating body, 8 a pump for guiding untreated water that could not be atomized by the rotating body 6 to the rotating body 6 again, 9 is a case A forming the atomizing unit 3, and 10 is the atomizing unit 3
Cases B and 11 that form the atomization unit 3 are cases C that form the atomization unit 3, and 18 is an air suction port.

Further, 16 is an indoor heat exchanger, 17 is a dew tray for collecting dew generated by the indoor heat exchanger 16, and 12 is an outlet for mist. Reference numeral 11 denotes a variable louver provided at the mist outlet (atomization outlet) 12.

Next, the operation of the atomizing unit configured as described above will be described.

First, when the indoor heat exchanger 16 acts as an evaporator during the cooling operation, dew is generated by heat exchange with the indoor air, and the generated dew becomes drain water to form a dew tray (drain). It is dropped on the saucer 17 and is rotated at a high speed through the drain hose 5a (about 850 in this embodiment).
(Rotated at 0 rpm) Dropping on the rotating body 6 by free fall.

When the drain water dropped on the rotating body 6 rotating at a high speed is radially scattered by the centrifugal force in the circumferential direction of the surface of the rotating body 6, a large number of drain water are provided on the surface of the rotating body 6. The drain water is violently collided with the raised portion 13, and as a result, the drain water instantly becomes a mist and soars upward in the surface of the rotating body 6 and is ejected from the mist outlet 12 to be discharged as mist into the outdoor atmosphere. It

Further, the drain water reliquefied on the inner wall surface of the case C11 is collected as untreated water 14 and is naturally dropped from the untreated water recovery passage 15 to the case B10 to be recovered.
It is dripped onto the rotating body 6 again by the pump 8 and becomes a mist, which is discharged from the mist blowout port 12 into the outdoor atmosphere. In this way, the untreated water 14 is circulated by the action of the pump 8 and finally the drain water becomes mist and is discharged into the outdoor atmosphere.

On the other hand, during the heating operation, the atomizing unit of the present invention is stopped by the control of the main body, and the mounting position is within the range where the drain water from the indoor unit 4 naturally flows as shown in FIGS. However, there is also the advantage that it can be installed anywhere.

[0015]

EFFECT OF THE INVENTION Since the drain water treatment apparatus of the separation type air conditioner of the present invention has the above-mentioned constitution, the drain hose for discharging the drain water can be eliminated and there is no fear of waste water treatment. Also, the drain hose piping work can be abolished, and various problems such as concern about drain clogging due to work, damage to the aesthetics of the pipe, and deterioration of the drain hose can be ameliorated.
