Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner in which an indoor side and an outdoor side are integrated.

[0002]

2. Description of the Related Art Conventionally, a small air conditioner mounted on a window for use has been provided with an atomizing device for treating dew water generated in an outdoor heat exchanger during a heating operation. This conventional example is shown in FIG.
More specifically, the atomizing motor c is provided above the cases a and b of the atomizing device, and the scattering disk e is provided in the atomizing chamber d in the cases a and b. By rotating e, the condensed water is sucked and atomized from the inlet f of the lower case b and discharged from the outlet g. The water droplets that could not be completely atomized by the scattering disk e returned to the outside of the lower case b from the drain port h provided at the bottom of the lower case b, and were repeatedly sucked up from the suction port f.

[0003]

However, in such a conventional atomizing apparatus, since the bottom of the atomizing chamber d is flat, when the amount of dew water increases, the air flow in the atomizing chamber d is reduced to the bottom of the atomizing chamber d. However, there is a problem that large water droplets fly out of the discharge port g or collide with dew water newly sucked up from the suction port f to increase noise.

[0004]

In view of this point, the present invention solves the above-mentioned drawbacks by focusing on this point. In particular, the structure of the main body is divided into an indoor side and an outdoor side, and both the indoor side and the outdoor side are separately formed. An air intake fan, a heat exchanger, and a heat pump cycle are provided, and an outdoor air inlet and an outdoor air outlet are provided on the back of the main body, and an outdoor air inlet, an outdoor heat exchanger, and an outdoor air blower are provided. A fan and an outdoor air outlet are sequentially communicated to form an outdoor air blowing path, and the dew water generated in the heat exchanger is guided to a lower portion of the outdoor heat exchanger, and the outdoor air outlet or the outdoor air blowing path is near the outdoor air blowing path. The atomization device is provided in the case, the atomization device is provided with an atomization chamber in the case, the atomization chamber is provided with atomization blades rotating horizontally, and a drainage channel is formed at the bottom of the atomization chamber. It is.

[0005]

In the heating operation, the condensed water generated in the outdoor heat exchanger 9 is received by the outdoor drain plate 21 and accumulates in the drain receiving portion 11 through the drain pipe 22. However, during the heating operation, the temperature of the outdoor heat exchanger 9 becomes low. Therefore, the drain motor 24 does not operate, and the condensed water is not jumped up to the outdoor heat exchanger 9 by the drain blade 23. The condensed water that has accumulated in the drain receiving portion 11 is condensed with the condensed water near the suction port 42 by the operation of the atomizing motor 36 provided in the atomizing device 25, and the lower end surface of the inverted conical suction part 29 is condensed with the dew water. In this state, the centrifugal force is received by the rotation of the atomizing motor 36, and the outer slope is raised upward in the upward direction of the outer slope by the combined force of the centrifugal force and gravity.

Immediately after the condensed water scatters radially in the horizontal direction from the circumferential portion of the scattering disk 30, the condensed water collides with the projection 33 and becomes fine and mist-like, and is discharged from the discharge port 41. Is formed into water droplets and is not atomized.
The process returns to 1 and is repeated by the suction port 42.

At this time, since the groove-shaped drain passage 43 is formed around the bottom of the atomizing chamber 28, the drain can be smoothly drained, and the air flow in the atomizing chamber 28 cannot be completely atomized at the bottom of the atomizing chamber 28. It is no longer possible to soak up the dew condensation water so that large water droplets jump out of the discharge port 41 or collide with the dew condensation water sucked up from the suction port 42 to increase noise. On the other hand, the air sucked from the upper direction or the side direction of the upper case 26 by the rotation of the atomizing blades 31 integrally provided on the upper surface of the scattering disk 30 passes through the suction port 37 and a part of the air is directly scattered. Part of the air is mixed with the dew water atomized by the disk 30, and a part of the air is blown toward the projection 33 through the ventilation path 34 between the blade ring 32 and the scattering disk 30, and dewed from the scattering disk 30. The water is further stirred to promote atomization, and is discharged from the outlet 41 through the outdoor outlet 7 and the outdoor air passage 16 of the air conditioner.

In order to prevent freezing of water, one end of the compressor 14 or the discharge pipe 5 of the compressor is heated at one end.
The other end is located in a drain receiving portion 11 provided on the base 8 by taking heat away.

In this heat pump cycle, during cooling, the refrigerant discharged from the compressor 14 flows through the four-way valve 48 to the outdoor heat exchanger 9 to dissipate heat, and is then depressurized by the cooling capillary tube 49. The low-temperature refrigerant enters the indoor-side heat exchanger 10, deprives the indoor side of heat, and returns to the compressor 14, so that condensation water is generated in the low-temperature indoor-side heat exchanger 10.
