Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to drain water generated from an indoor heat exchanger during heat exchange of indoor air during cooling, and to outdoor heat exchange during a defrosting cycle during heating. This relates to the treatment of water generated by melting frost that has adhered to vessels.

BACKGROUND OF THE INVENTION Generally, when air is cooled by an indoor heat exchanger, airborne particles are condensed to form drain water.

One method for discharging this drain water outdoors is to make it into a mist using a sprayer and discharge it outdoors.

An example of the conventional air conditioner mentioned above will be described below with reference to the drawings.

FIG. 7 is a side view showing a conventional air conditioner installed in a window, where 1 is the main body of the air conditioner and 2 is a fog. FIG. 8 is a sectional view of a conventional air conditioner body 1 (hereinafter referred to as the body 1), in which 3 is an indoor heat exchanger, 4 is a water tray, 5 is a sprayer, 6 is a discharge port, and 7 is an outdoor side. It is a heat exchanger.

Drain water treatment of the air conditioner configured as above will be explained.

1. In FIG. 8, dew generated from the indoor heat exchanger 3 by heat exchange with indoor air is collected in a water tray 4, and after being atomized by a sprayer 5, it is discharged outdoors from a discharge port 6. and is scattered. That is, as shown in FIG. 7, fog 2 is scattered outside from the main body 1 installed in the window.

Problems to be Solved by the Invention However, with the above configuration, the particles of the mist 2 generated by the sprayer 5 only have a small initial velocity given by the vibrator of the sprayer 5, and the particles on the outdoor side of the main body 1 There was a problem in that the smoke remained in the vicinity, giving the user a sense of uneasiness as if smoke was being generated due to equipment failure.

Further, in the defrosting cycle during heating, the water generated when melting the frost adhering to the outdoor heat exchanger 7 cannot be turned into mist and discharged outdoors in winter.

In view of the above-mentioned problems, the present invention atomizes drain water generated during cooling operation and molten water generated during the defrosting cycle during heating operation into a mist, and accumulates the mist in the vicinity of the outdoor side of the main body 1 in the form of smoke. To provide an air conditioner that can discharge air to the outdoors without causing air pollution.

Means for Solving the Problems In order to solve the above problems, the air conditioner waste water treatment device of the present invention includes an outdoor heat exchanger, and a heat exchanged air that passes through the outdoor heat exchanger. An outdoor side blower for sending out outdoor air from an outdoor air outlet of the air conditioner main body (hereinafter referred to as the main body), and an outdoor air blower disposed below the outdoor heat exchanger, and below the outdoor air outlet of the main body. a water tray provided in an extended manner; a sprayer provided below the outdoor outlet of the air conditioner main body and within the cylindrical wall of the water tray; a communication port leading to the sprayer through the cylindrical wall; It is equipped with a heating means for heating the water collected in the water tray.

Effect of the Invention With the above-described configuration, the present invention collects condensed water generated during cooling or water generated by melting frost adhering to the outdoor heat exchanger during defrosting during heating into a water tray, and collects this water into a water tray. When the water temperature is below 0°C, the heating means is activated to prevent the recovered water from freezing. In addition, by locating the sprayer within the cylindrical wall of the water tray, water can be stored up to a level higher than the discharge port, and water can be supplied under the water pressure to perform spraying.

Furthermore, the dispersion speed of the sprayed mist can be accelerated by the blowing air sent out through the outdoor heat exchanger by the outdoor fan, and the water collected in the water tray from the main unit to the outdoors can be turned into a mist. It can be discharged.

Reference numeral 3 indicates an ejection hole of the sprayer 18, and reference numeral 26 indicates a communication port leading to the intake port 27 of the sprayer 15 through the cylindrical wall 21.

FIG. 5 is a flowchart showing operating conditions and stop conditions for the heating means 19 in the air conditioner, and FIG. 6 shows a control circuit for the heating means 19 in the air conditioner. In the figure, 24 is a sensor that detects the temperature of the water 20 collected in the water tray 15, and 25 is a first control device.

The operation of the waste water treatment device for an air conditioner configured as described above will be explained below using FIGS. 1 to 6.

First, considering the cooling operation, dew condensed on the fin surface of the indoor heat exchanger 12 is collected in the dew pan 16, drips onto the fin surface of the outdoor heat exchanger 13, and then collected in the water pan 15. Ru.

Next, considering the heating operation, the outdoor heat exchanger 13 functions as an evaporator, causing frost to adhere and grow on the fin surface.
For example, when the pipe temperature of the outdoor heat exchanger 13 falls below a certain level, defrosting operation is started, and the frost melts and the outdoor heat exchanger 1
Water is stored in a water tray 15 disposed below 3.

Especially when considering heating operation, there is a risk that the water collected in the water tray 15 will freeze at a water temperature below O'C. is provided, and the water temperature of the water 20 is, for example, 0.
°C or below, the relay contact 27 in the first control device 25 is closed and the heating means 19 is energized, as shown in FIG. By turning off the current, the water 20 collected in the water tray 15 can be heated and prevented from freezing.

On the other hand, the water 20 is gradually collected in the water tray 15, and when the water surface height gradually increases and the water pressure exceeds a certain level, the communication port 26
As a result, the water collected in the water tray 15 is supplied from the suction port 27 of the N jet unit 18, and further due to the vibration of the vibrator 22,
It is sprayed from the discharge port 23. Furthermore, the outdoor side blower 14
After passing through the outdoor heat exchanger 13, the main body 1

Further, a flowchart regarding the operation of the heating means 19 is shown in FIG.

Effects of the Invention As described above, the present invention includes an outdoor side blower for sending air that has passed through the outdoor heat exchanger to the outdoors from an outdoor side outlet of the main body, and an outdoor side blower disposed below the outdoor side heat exchanger. and a water tray extending below the outdoor air outlet of the main body;
By providing a sprayer below the main body outlet to atomize the water collected in the water tray, the frost discharged by the air blown from the outdoor outlet can be accelerated. This allows the fog to be dispersed far away without remaining near the outside of the main unit.

Furthermore, the heating means for heating the water collected in the water tray can prevent the water collected in the water tray from freezing even in winter, and the cylindrical wall of the water tray is provided with a communication port to the sprayer. As a result, a high water level can be obtained without submerging the sprayer, and pressure can be applied to the vibrator without using other means, making it possible to spray at all times, and not only during summer cooling. Outside temperature is 0
Even during heating operation in winter when the temperature is below ℃, the water generated during the defrosting cycle can be turned into mist and drained from the main unit.

Furthermore, since the sprayer is surrounded by a cylindrical wall, the nozzle orifice will not be submerged in water, and there will be no abnormal noise, insufficient output, or even a risk that the sprayer will not be able to operate. Furthermore, since the height of the cylindrical wall can be appropriately selected, restrictions on the height of the atomizer are significantly relaxed, and a small atomizer can be used with optimum output.
