DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention treats drain water (condensed water) condensed in a heat exchanger by atomizing the condensed water in an atomizing device and discharging the discharged water into the atmosphere through a discharge port. It relates to an air conditioner.

[0002]

2. Description of the Related Art In a conventional air conditioner of this type, for example, an integrated air conditioner, drain water is generally generated in an indoor heat exchanger during cooling and in an outdoor heat exchanger during heating. Since this drain water is unnecessary, conventionally,
It was common to discharge outside the room with a drain hose or drain pipe. However, when it is requested to install an air conditioner in an environment where installation work such as a drain hose cannot be performed at all, since the drain water cannot be treated, it has been impossible to install the air conditioner. .

[0003] Therefore, a condensed water atomizing type integrated air conditioner that atomizes the drain water using an atomizer and discharges the air into the air so that the drain water can be treated without installing a drain hose or the like. The machine is Japanese Patent Publication No. 3-54248, Shokai Sho 62-
No. 143126, Japanese Utility Model Laid-Open No. 1-63929, and the like.

An example of such an air conditioner will be described with reference to FIGS. FIG. 9 is a perspective view of an installed state in which an integrated type air conditioner of a condensed water atomization type is installed on a window frame as viewed from the outdoor side, and FIG. 10 is an external perspective view of an installed state in a window viewed from the indoor side. FIG. 11 is a rear view of the air conditioner main body viewed from the outdoor side, and FIG. 12 is a side sectional view of a main part of the air conditioner main body. 1 is an air conditioner body, 2 is an atomized drain water outlet, 3
Is a window, 4 is dew condensation water, 5 is a rear plate of the air conditioner main body 1, 6 is an outdoor air outlet after heat exchange with the outdoor heat exchanger 10, 7
Is an outdoor air inlet, 9 is an atomizing device, 11 is a substantially horizontal rib structure, and 19 is a first drain pan.

[0005] In the air conditioner having the above configuration, the atomizing device 9 installed in the air conditioner main body 1 is operated by heating the air conditioner main body 1, and the drain is discharged from the atomized drain water discharge port 2. Water is discharged as fog. The discharged mist adhered to the window 3 and the like and formed dew to form dew water 4 and drip downward.

Further, the applicant has filed a separate patent application (Japanese Patent Application No. 5-32181) for an air conditioner that atomizes drain water by using the above atomizing device and discharges the air into the air. That is,
Drain water atomized by a rotary atomizing means is placed on an outdoor air blower and discharged outdoors.

[0007]

However, when the drain water is atomized and discharged into the air by the air conditioner having the above structure, the area around the discharge port of the atomized drain water is not only blown by the atomizing means itself but also in the outdoor side. There is a complicated flow of wind, such as the wind from a blower and the natural wind of the outside air outside, and it is impossible to fix the flow in a fixed direction. Therefore, atomization of the rear part (outdoor side) of the main body of the air conditioner There is a problem that the atomized drain water condenses and drops around the drain water outlet.

[0008] Therefore, the present invention is directed to guiding the condensed drain water to the inside of the air conditioner main body, collecting and discharging the condensed water again to the outside of the air conditioner main body to wet the peripheral portion. It is to prevent.

[0009]

The present invention has the following arrangement to solve the above-mentioned problem.

In an air conditioner for treating the drain water by atomizing the drain water condensed by the heat exchanger with an atomizer and discharging the atomized water through a discharge port, the atomized drain water is removed. The apparatus is provided with a water guiding means for guiding the dew water generated by the dew condensation phenomenon to the atomizing device when discharging from the discharge port.

[0011]

According to the air conditioner of the present invention having the above structure, when the atomized drain water is discharged from the discharge port, the dew water generated by the condensation phenomenon is guided to the atomizing device by the water guiding means. Prevents the window frame and walls around the atomized drain water outlet from getting wet by the atomized drain water.

In many cases, the air conditioner is installed on a window frame so that the window 3 can be freely opened and closed. Therefore, if the water guide plate 12 becomes large enough to protrude from the window 3, the opening and closing of the window 3 is hindered. However, since the water guide plate 12 is made of a soft material such as soft vinyl chloride, when the window is closed, if it is large, it is easily bent without hindrance.

The liquid is guided to the second drain pan 28 through the drain guide 32. This drain water is turned into water droplets by the rotation of the lifting disk 29 directly connected to the motor, and is drawn up toward the outdoor heat exchanger 10 acting as a condenser. The water droplets sprayed on the high-temperature outdoor heat exchanger 10 take away the heat and evaporate, and are discharged by the outdoor blower fan 17 to the outside together with the outdoor air having completed the heat exchange. At this time, the condensation capacity of the outdoor heat exchanger 10 can be increased by the evaporation of the drain water.

Next, during the heating operation, the outdoor heat exchanger 1
When 0 acts as an evaporator, in heat exchange with outdoor air, dew is generated and the water is dropped into the first drain pan 19 as drain water. The drain water drops through the drain guide 20 onto the rotary atomizer 8 which is rotating at a high speed by the DC motor 24 (rotating at about 8500 rpm in the present embodiment) by gravity.

Crash violently. As a result, the drain water instantaneously becomes a mist, and the drain water soars upward from the surface of the rotary atomizer 8 due to the centrifugal fan effect of the blade 23 provided on the back surface of the rotary atomizer 8, from the mist outlet 34. The mist 2 is blown out and flows on the air blown by the outdoor blower fan 17 from the atomized drain water discharge port 2 to the outside.
Discharged as 6.

A part of the discharged mist 26 adheres to the water guide plate 12 due to the flow of the outdoor wind, and dew forms on the water guide plate 12. The condensed water 4 forms a water guide plate 12 (inclined portion 12).

The drain water reliquefied on the inner wall surface of the atomizing device 9 is collected as untreated water, and is collected in the untreated water recovery passage 25.
From the drain pan 28 to the second drain pan 28. The untreated water collected in the second drain pan 28 is pumped by the first drain pan 19 by the rotation of the lifting disk 29 directly connected to the motor, and is again dropped from the drain guide 20 to the rotary atomizer 8. Is atomized as follows. In addition,
Reference numeral 36 denotes a discharge high-temperature portion of the refrigeration cycle, which heats the drain water in order to prevent the drain water from freezing.
