[0002]

2. Description of the Related Art A small-sized air conditioner conventionally used by being attached to a window has been improved so that installation work can be easily performed.
No. 8 proposes that during cooling, the condensed water generated in the indoor heat exchanger is guided to the outdoor side, and the condensed water is sprayed to the high-temperature outdoor heat exchanger to evaporate, and as steam from the outdoor air outlet. Draining work is unnecessary because it is equipped with an atomization device to discharge dew outdoors and to use as a heater even in winter by switching the refrigeration circuit, and to treat dew water generated in the outdoor heat exchanger during heating operation. It was useful.

However, in such a conventional air conditioner, the discharge port c is located on the side of the case b because the atomizing motor a is provided above the case b.
Large condensed water, which cannot be directly atomized, may fly out from the discharge port c, and there is a problem that water drops may be applied to a pedestrian when an air conditioner is installed in a room facing the road. In the case of a type of atomizing device in which the atomizing motor is provided at the lower part of the case and the discharge port is located on the upper surface, there is no fear of water droplets jumping out. There was no problem, but if the case was broken or a gap was formed, dew water could enter the motor and cause a failure.

[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 atomizing device is provided with an atomizing motor above the case, is provided with atomizing blades rotating in the horizontal direction in the case, and a discharge port for discharging atomized dew water on the side surface of the case. Is provided, and the outlet is provided from the atomizing blade. Those provided above.

In the cooling operation, dew water generated in the indoor heat exchanger 11 is received by the indoor drain plate 20 and passes through the gutter 21 to the lower portion of the outdoor heat exchanger 10, the outdoor drain plate 22, and the drain pipe 23. The water accumulates in the drain receiving portion 12, is jumped up to the outdoor heat exchanger 10 by the drain blade 24, is evaporated by the high-temperature heat exchanger 10, and is exhausted from the outdoor outlet 8 as water vapor. During the cooling operation, the atomizing device 26 is not operated for the purpose of cooling the outdoor heat exchanger 10 to improve the efficiency of heat exchange.

During heating, the dew water generated in the outdoor heat exchanger 10 is received by the outdoor drain plate 22 and accumulates in the drain receiving portion 12 through the drain pipe 23. However, during the heating operation, the temperature of the outdoor heat exchanger 10 becomes low. Therefore, the drain motor 25 does not operate, and the condensed water is not jumped up to the outdoor heat exchanger 10 by the drain blade 24.
From the drain inlet 45,
6 and through the drain introduction path 46 to the guide section 43. When the lower end surface of the inverted conical suction portion 30 of the atomizing blade 31 is in contact with the drain water from the guide portion 43, the drain water in contact with the conical outer slope by the rotation of the atomizing motor 32 is The outer slope is subjected to centrifugal force due to rotation, and rises on the outer slope by the action of a component component of the upward slope component of the outer slope due to the combined force of the centrifugal force and gravity.

Drain water scatters radially from the circumferential portion of the atomizing blade 31 in a horizontal direction perpendicular to the rotation axis 38, and water droplets separated from the circumferential portion collide with the column 41 or the wall of the case 27 at high speed. The energy makes the particles finer and becomes mist, and is discharged from the discharge port 42. Since the discharge port 42 is located above the atomizing blade 31, large dew water does not jump out of the discharge port 42.

The other end is the base 9
Is located in the drain receiving portion 12 provided in the above.

In this heat pump cycle, during cooling, the refrigerant discharged from the compressor 15 flows through the four-way valve 49 to the outdoor heat exchanger 10 to dissipate heat, and is then depressurized by the cooling capillary tube 50. Since the low-temperature refrigerant enters the indoor heat exchanger 11 to take heat from the indoor side and returns to the compressor 15, dew condensation occurs in the low-temperature indoor heat exchanger 11. Further, at the time of heating, the refrigerant discharged from the compressor 15 flows through the four-way valve 49 to the indoor heat exchanger 11 side to dissipate heat to heat the room, and then the low-temperature low-pressure reduced by the heating capillary tube 51.

Is to which frost adheres.

The sequence at the start of operation will be described. If an operation switch provided on the operation unit 5 is turned on as shown in FIG. 10, it is determined whether the operation is heating operation or cooling operation. The four-way valve 49 is turned on, the drain motor 25 and the compressor 15 start rotating, and when the room temperature reaches the set temperature, the compressor 15 stops and the compressor 15 performs an ON-OFF operation depending on the room temperature and the set temperature. In the case of the heating operation, the outside air temperature is detected by an outside air temperature thermometer (not shown), and when the outside air temperature is 3 ° C. or more, the compressor 15 and the atomizing motor 26 are operated immediately, and the outside air temperature becomes 3 ° C. If it is smaller, the condensed water remaining in the previous operation may be frozen, so only the compressor 15 is operated and the atomizing motor 26 is operated 15 minutes after the condensed water frozen by the heat pipe 52 is melted. The condensed water is atomized and discharged outside, and the compressor 15 performs the ON-OFF operation as in the cooling.

The flow of the dew condensation water will be described. During the cooling, the dew condensation water generated in the indoor heat exchanger 11 is received by the indoor drain plate 20 and passes through the gutter 21 to the outdoor heat exchanger 1.
0, the outdoor drain pan 22, the drain pipe 23, and accumulates in the drain receiving portion 12. The drain blade 24 jumps up to the outdoor heat exchanger 10 and the high-temperature heat exchanger 10
, And is exhausted from the outdoor outlet 8 as steam. During the cooling operation, the atomizing device 26 is not operated for the purpose of cooling the outdoor heat exchanger 10 to improve the efficiency of heat exchange.

During heating, the dew water generated in the outdoor heat exchanger 10 is received by the outdoor drain plate 22 and accumulates in the drain receiving portion 12 through the drain pipe 23. However, during the heating operation, the temperature of the outdoor heat exchanger 10 becomes low. Therefore, the drain motor 25 does not operate, and the condensed water is not jumped up to the outdoor heat exchanger 10 by the drain blade 24.
From the drain inlet 45,

When the lower end surface of the inverted conical suction portion 30 of the atomizing blade 31 is in contact with the drain water from the guide portion 43, the drain water in contact with the conical outer slope by the rotation of the atomizing motor 32 is The outer slope is subjected to centrifugal force due to rotation, and rises on the outer slope by the action of a component component of the upward slope component of the outer slope due to the combined force of the centrifugal force and gravity.

The drain water scatters radially from the circumferential portion of the atomizing blade 31 in a horizontal direction perpendicular to the rotation axis 38, and water droplets separated from the circumferential portion collide with the column 41 or the wall of the case 27 at high speed. The energy makes the particles finer and becomes mist, and is discharged from the discharge port 42. Since the outlet 42 is located above the atomizing blade 31, large dew water does not jump out of the outlet 42. Further, since the drain water rises extremely easily on the outer slope of the conical shape, normal and good atomization can be performed even with the drain water mixed with dust.

By installing the atomizing device 26 in this way, it becomes possible to provide an air conditioner that does not need to perform drain work even with a heat pump type. Further, the atomizing motor 32 of the atomizing device 26 is provided above the atomizing chamber 29 so as to suck the dew condensation water from the lower part of the atomizing chamber 29 and atomize the same. 2
