BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid atomizing apparatus for converting a desired liquid into an atomized state. Further, the present invention relates to a drain water treatment apparatus for an air conditioner, and a refrigeration cycle means in which a compressor, a four-way valve, a condenser, a decompression means, and an evaporator are connected through a refrigerant pipe through which a refrigerant circulates, An apparatus for treating drain water generated in an integrated heat pump type air conditioner having, for example, an air conditioner for a window, having a blower for sending air to indoor and outdoor heat exchangers in the same main body. It is about.

[0002]

2. Description of the Related Art In this type of integrated heat pump type 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, it has conventionally been general to drain the drain water to the outside with a drain hose or a drain pipe. However, drainage work to install drain hoses and the like is relatively complicated. Moreover, when it is requested to install the air conditioner in an environment where installation work such as a drain hose cannot be performed at all, since drain water cannot be treated, installation of the air conditioner becomes impossible. I was Therefore, some treatment means capable of treating drain water without installing a drain hose or the like is required.

Conventionally, as one of the processing means, there is a technique in the air conditioner, in which drain water generated during cooling is atomized and discharged outside the room. This technology is disclosed in
No. 23, which has a structure as shown in FIG.

That is, in FIG. 24, dew is generated in the heat exchanger 2 in the air conditioner main body 1. Immediately below the heat exchanger 2, a receiving tray 4 for receiving drain water dripping from the heat exchanger 2 is arranged. The receiving tray 4 is provided by an ultrasonic atomizer 5 and a passage 6 installed on the rear side inside the air conditioner. It is connected. And the drain water in the saucer 4
It flows through the passage 6 and is supplied to the ultrasonic sprayer 5 by gravity. The drain water is atomized by the ultrasonic atomizer 5 and is jetted to the mist discharge nozzle 7. The mist ejected to the mist ejection nozzle 7 is discharged from the mist ejection port 8 to the outside (or outdoors).

[0005] As another method of the above-mentioned processing means, there is a technique in which drain water is stirred up in a condenser during cooling operation. This technique is disclosed in Japanese Utility Model Publication No. 56-50339 and has a structure as shown in FIG. That is, as shown in FIG. 25, the drain water generated from the indoor heat exchanger 2 is supplied through the hose 6a.
It is sent to the drain pan 10. In addition, a splasher 9 made of a disc is provided so as to contact the drain water in the drain pan 10. During the cooling operation, when the splasher 9 rotates, the drain water accumulated in the drain pan 10 rotates together with the splasher 9 and is dispersed as small water droplets in the circumferential direction of the splasher 9 due to the peripheral speed and the centrifugal force. . As a result, water droplets are applied from below to above the outdoor heat exchanger (condenser) 11, and the water droplets are evaporated by the heat of the outdoor heat exchanger 11 and the air blower.

[0006]

However, each of the structures shown in FIGS. 24 and 25 has some problems, and the drain water treatment method for the integrated heat pump type air conditioner has some problems. There was nothing practical.

More specifically, the structure shown in FIG. 24 can be used in principle during a heating operation, but since the structure is such that the drain water is atomized and constantly discharged outside, the condenser during the cooling operation is used. It was difficult to improve the condensation efficiency by scattering the drain water toward. If the atomizer is composed of an ultrasonic vibrator, periodic cleaning of the vibrator is necessary to prevent the atomization ability from being reduced due to the dust mixed in the drain water adhering to the vibrator. Therefore, structural and usage restrictions are increased. Further, since the atomization capability of the vibrator unit can generally be only about 500 cc / h, a large number of ultrasonic vibrator units must be used to treat drain water exceeding 1000 cc / h as a normal air conditioner. It costs.

Further, in the structure shown in FIG. 25, it is difficult to discharge the drain water particles as mist to the outside of the room because the particles of the drain water swept up by the disk 9 are too large. There were various problems.

In connection with the structure shown in FIG.
FIG. 26 shows an example of an air conditioner dedicated to cooling, which treats drain water with a condenser. That is, in FIG. 26, the drain water that has flowed out of the indoor heat exchanger (evaporator) 2 during the cooling operation temporarily accumulates in the drain pan 10. Drain water collected in a drain pan 10 is swept up by a splasher (disk-shaped blade) 9 and applied to the surface of an outdoor heat exchanger (condenser) 11 to perform an evaporative diffusion process by heat of the condenser and wind of a blower. The air conditioner shown in FIG. 26 is a cooling only machine. The drain water treatment cannot be performed during the heating operation in a cooling / warming type air conditioner that applies this as it is or a general conventional cooling / heating operation type window air conditioner. This is because the refrigerating cycle is reversed during cooling and heating by the operation of the four-way valve, and the drain heat cannot be evaporated because the outdoor heat exchanger becomes an evaporator (heat absorbing side) during heating.

On the other hand, it is assumed that drain water treatment is performed during cooling and heating of the air conditioner.
No. 143126 has been proposed. In this publication, an atomizing device is provided, which drives the atomizing device so that the direction of jet of the mist is directed toward the condenser during the cooling operation, and is jetted toward a predetermined portion other than the evaporator during the heating operation. A drain processing device has been proposed. However, this processing apparatus has a complicated structure because the atomizing apparatus is structured to be directed to the outdoor and outdoor heat exchangers. Further, an ultrasonic vibrator is usually used in this atomizing device, and the above-mentioned problems caused by the ultrasonic vibrator cannot be solved.

An integrated air conditioner with a drain water treatment apparatus that atomizes drain water without using an ultrasonic vibrator is disclosed in Japanese Utility Model Laid-Open No. 1-63929. The drain water treatment device disclosed in this publication is intended to be able to treat drain water both at the time of cooling and at the time of heating with an inexpensive configuration. That is, as shown in FIG. 5 of the above-mentioned publication, this drain water treatment apparatus immerses the conical side surface portion of the lower part of the spray ring (11) in the drain water in the collection dish (6), and sprays the water. Ring (11)
Is rotated so that drain water climbs on the inner wall of the conical side shape portion by centrifugal force due to the rotation. Further, the drain water that has climbed is scattered in the form of a mist in the dish-shaped portion above the spray ring (11).

However, the drain water treatment apparatus disclosed in the above-mentioned publication has a loud noise due to the centrifugal type in which the spray ring rotates at a high speed. In addition, there is a problem that dust adheres to the inner wall of the spray ring and is fixed, and the suction of drain water becomes worse, so that it is necessary to periodically clean the spray ring.

When the outside air temperature becomes 0 ° C. or less in winter, drain water accumulated near the splasher may freeze and the splasher may not operate. In such a case, the drain water cannot be subjected to the evaporating process, and problems such as excessive accumulation of the drain water occur.

Further, there has not been an atomizing device for efficiently atomizing a liquid such as water with a simple and inexpensive configuration.

The present invention has been made in view of the above problems, and in order to realize drain water treatment during cooling and heating of an integrated air conditioner, an outdoor heat exchanger is used during cooling. It is an object of the present invention to provide a drain water treatment device for an air conditioner, which performs a drain water evaporation process and can atomize drain water by a rotary atomizer during heating and discharge the drain water to the outside. Also,
An object of the present invention is to provide a drain water treatment device for an air conditioner that can prevent the drain water from freezing even when the outside air temperature becomes 0 ° C. or less.

[0016]

The present invention has the following arrangement to solve the above-mentioned problems. That is, the present invention relates to a refrigerating cycle unit in which a compressor, a four-way valve, a condenser, a decompression unit, and an evaporator are connected through a refrigerant pipe through which a refrigerant circulates, and wind to a heat exchanger on the indoor side and the outdoor side. in the integrated heat pump type air conditioner and a blower means having within the same body a letter, a first drain collecting means for collecting drain water condensed in the heat exchanger of the indoor side or outdoor side,

[0019] Then, the onset Ming, at ambient temperature is below a predetermined temperature, is to instantly predetermined rotation speed driving liquid atomizer from the stop of the heating operation after the predetermined time has elapsed.

Therefore, the drain water treatment apparatus of the present invention has the above-described configuration, and without using an atomizer using an ultrasonic vibrator, drain water is dropped on a rotating body to form a mist (rotary atomizing means). The collision between the rotating shaft of the rotating body and the rib-shaped convex portion formed substantially concentrically forms a mist,
The mist is put on the wind of an outdoor blower and discharged to the outdoor. As a result, drainage work by the drain hose can be eliminated, and the integrated heat pump type air conditioner can be installed even in a place where drainage work cannot be performed. In addition, since the rotary atomizing means is used and the nozzle, the switching valve, the vibration element, etc. are not used at all, it can be configured so as not to cause clogging due to dust or the like mixed in the drain water and to reduce the drain processing capacity. It does not require regular cleaning and is highly reliable. In addition, if drain water is supplied to the outdoor heat exchanger, the condensation efficiency of the heat exchanger can be improved.

[0037]

Further, according to the present invention, the drain water is stirred by the drain water stirring means when the outside air temperature becomes 0 ° C. or less, and the freezing of the drain water is reliably prevented. Here, the stirring means only stirs the water, and the kinetic energy and friction energy (drain water collecting means such as friction with a drain pan) due to the movement of the drain water exceed the latent heat of vaporization of the drain water, Freezing is prevented.

Numeral 35 is an atomization accelerating projection provided on the atomization surface of the rotary atomizer 23, and in the present embodiment, has a concentric rib shape. The air conditioner of the first embodiment has a refrigeration cycle protection device. This protection device
During the heating operation, the outside air temperature is low and the evaporation temperature of the refrigerant is roughly
When the temperature becomes 1 ° C. or less, frost adheres to the outdoor heat exchanger 16, so that the indoor blower fan 15 and the outdoor blower fan 17 are stopped to start the defrosting operation.

Next, the operation of the air conditioner of the first embodiment having the above configuration will be described. FIG. 5 is a conceptual diagram for explaining the operation, and a cooling operation of the air conditioner will be described with reference to FIGS. During the cooling operation, the indoor heat exchanger 14 acts as an evaporator, so that dew is generated by heat exchange with indoor air. This dew,
The water becomes the drain water and is dropped on the drain tray 31, passes through the drain guide 32, and is collected in the second drain pan 28.
The drain water is turned into water droplets by the rotation of the return disk 29 (rotated at about 2500 rpm in the present embodiment) directly connected to the motor 30 for lifting, and the outdoor heat exchanger 16 acting as a condenser is formed. To be lifted up.

In this manner, the water drops are discharged from the high-temperature outdoor heat exchanger 1.
6, the heat is removed, the heat is evaporated, and the air is exhausted by the outdoor fan 17 together with the outdoor air having undergone heat exchange. Also, at this time, due to evaporation of the drain water,
The condensation capacity of the outdoor heat exchanger 16 can be increased.

Next, the heating operation will be described with reference to FIGS. 3, 4, and 6. FIG. FIG. 6 is a conceptual diagram for explaining the operation. During the heating operation, the outdoor heat exchanger 16 acts as an evaporator, so that in the heat exchange with outdoor air, if the evaporation temperature of the refrigerant is approximately -1 ° C. or higher, dew is generated to form drain water. Is dropped on the first drain pan 19. This drain water is rotated at high speed through the drain guide 20 after dust and the like mixed in the drain water are trapped and settled by the numerous protrusions 21 protruding from the bottom surface of the first drain pan 19. (In this embodiment, about 8
(Rotation at 500 rpm) Drop on the rotary atomizer 23 in a natural fall manner. When the drain water dropped on the rotary atomizer 23 rotating at high speed is radially scattered by centrifugal force in the circumferential direction of the surface of the atomizer 23, a large number of drain waters are provided on the surface of the atomizer. Violently collides with the raised portion 35. As a result, the drain water instantaneously forms a mist, soars upwards on the surface of the rotary atomizer 23, blows out from the mist outlet 34, and is discharged outside as a mist 26 by the air blown by the outdoor blower fan 17. You.

The drain water re-liquefied on the inner wall surface of the atomizing chamber 33 is collected as untreated water 27, falls from the untreated water recovery passage 25 to the second drain pan 28, and is collected. Untreated water 27 collected in the second drain pan 28
Is lifted up to the outdoor heat exchanger 16 by the rotation of the disk 29 directly connected to the lifting motor 30. Thereafter, the drain water drips from the outdoor heat exchanger 16 and is collected in the first drain pan 19, and is again dropped from the drain guide 20 to the rotary atomizer 23 to be atomized as described above. In this way, the untreated water is circulated.

During the heating operation, when the evaporation temperature of the refrigerant is approximately -1 ° C. or less, the surface of the outdoor heat exchanger 16 becomes 0 ° C. or less, and no more dew is generated.
Frost begins to adhere. When the frost on the outdoor heat exchanger 16 reaches the entire area, the indoor blower fan 15 and the outdoor blower fan 17 are stopped by the operation of the cycle protection device (not shown), and defrosting is performed. Start driving.

By this defrosting operation, the outdoor heat exchanger 16
The frost and ice adhering to the hopper begin to melt and collect as a defrost water in the first drain pan 19 at once, and flow down to the rotary atomizer 23 through the drain guide 20. At this time,
Since the outdoor blower fan 17 has been stopped for the purpose of increasing the defrosting effect, the defrost water atomized by the atomizing device 22 is discharged to the outside by being blown by the outdoor blower fan 17. Can not do it. Therefore, in the embodiment, the atomizing device 22 is stopped during the defrosting operation. Therefore,
The defrost water that has flowed down from the drain guide 20 to the rotary atomizer 23 is directly collected as untreated water 27 through the untreated water recovery passage 25 to the second drain pan 28, and the defrost operation is performed. Stored until finished.

When the defrosting operation is completed and the operation returns to the heating operation, the defrosted water stored in the second drain pan 28 is heated by the discharge high temperature section 36 of the refrigeration cycle, and the water temperature rises. After that, the defrost water is swept up by the outdoor heat exchanger 16 by the rotation of the disk 29, and collects in the first drain pan 19 again. Like the drain water, the collected defrost water is dropped from the drain guide 20 onto the rotary atomizer 23 rotating at a high speed of about 8500 rpm. As a result, the defrost water instantaneously becomes a mist and soars upward in the rotary atomizer surface 23, and is discharged from the mist outlet 34 to the outside by the blowing of the outdoor blowing fan 17 as described above. .

In the first embodiment, the atomizing device 22 uses a substantially disk-shaped atomizer 23 and a DC motor 24.
Is used to rotate the atomizer 23 at high speed, but other means can also obtain the effect of the present invention as long as the means is a drain water atomizing means using a means for dropping drain water on a rotating body. In the first embodiment, the drain water on the indoor side is guided to the second drain pan 28 by the drain guide 32. However, the present invention may be applied to a configuration in which the drain water is guided to the first drain pan 19. Needless to say, the effect of can be obtained.

(Second Embodiment) Next, a second embodiment of the present invention will be described. 7 to 9 are explanatory views of the configuration of the integrated air conditioner of the second embodiment. 8 and 9 show the lower part of the outdoor heat exchanger 16 in FIG. 7 as viewed from the direction of arrow A in FIG. 7 to 9, the same portions as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.

The second embodiment differs from the first embodiment in that the outdoor heat exchanger 16a is, as shown in FIG.
It consists of two heat exchange parts 16a1 and 16a2, and these heat exchange parts 16a1 and 16a2 are arranged with a predetermined gap 16b in the blowing direction. In addition, the outdoor heat exchanger 16a is provided so that the drain water scraped up by the rotation of the disk 29 does not hit the outdoor heat exchanger 16a as desired.
The disk 2 is located on the lower side between the heat exchange portions 16a1 and 16a2.
An elongate lid member 40 that covers the upper part 9 is provided. Further, the heat exchange section 16 outside the outdoor heat exchanger 16a
Below the a2, a shielding plate 19a for guiding the drain water to the first drain pan 19 without being applied to the exchange section 16a2 is provided. The cover member 40 is rotated by an opening / closing motor 41 about a longitudinal direction as an axis. This lid member 40 is
It opens in a direction parallel to the direction in which the drain water is pumped up during cooling (FIG. 8), and closes at a specified angle with the direction in which the drain water is pumped up during heating, leading the drain water together with the shielding plate 19a. The water channel 43 is formed (FIG. 9). As shown in FIG. 9, when the lid member 40 is closed, a water conduit 43 is formed to guide the drain water swept up from the lower surface side to the first drain pan 19 to the atomizing device 22.
Further, a temperature sensor 42 composed of, for example, a thermistor for detecting the outside air temperature is provided inside the upper part of the outdoor heat exchanger 16a.

During the heating operation or during the stop, the outside air temperature becomes zero.
° C or less, and in order to prevent the drain water accumulated in the second drain pan 28 from freezing and making the rotation of the disc 29 impossible, when the outside air temperature sensor 42 reduces the outside air temperature to 0 ° C or less. By rotating only the disk 29, the freezing of the drain water is prevented.

Next, the operation of the integrated air conditioner of the second embodiment will be described. The overall operation is performed according to the flow of FIG. Concerning the treatment of the drain water during the heating operation, the refrigerating cycle is reversed from that during the cooling operation, so the condenser becomes the indoor heat exchanger 14, the evaporator becomes the outdoor heat exchanger 16a, and the drain water becomes the evaporator. The surface of the outdoor heat exchanger 16a is atomized by the atomizing device 22 through the first drain pan 19, and the remaining untreated water 27 accumulates in the second drain pan 28. Regarding the drain water treatment path, refer to the second drain pan 2
The drain water accumulated in 8 is swept up to the water conduit 43 by the rotation of the disk 29 and guided to the atomizing device 22. The atomizing device 22 discharges the drain water in the form of a mist outside the room. In addition, atomization device 2
The remaining drain water that could not be treated in Step 2 returns to the second drain pan 28. At the time of heating, as shown in FIG. 9, the water conduit 43 is formed in a state where the lid member 40 is closed at the specified angle, and the drain water is guided to the atomizing device 22.

On the other hand, during cooling, as shown in FIG. 8, the motor 41 rotates to open the lid member 40, and the outdoor heat exchanger 16 is opened.
The drain water is swept up to a (during cooling, the refrigerating cycle is reversed from that during heating, the outdoor heat exchanger 16a becomes a condenser, and the indoor heat exchanger 14 becomes an evaporator). In addition, the shielding plate 19a has the first fog generated in the outdoor heat exchanger 16a.
A water passage is ensured so as not to be inconvenient when flowing down the drain pan 19.

Here, the outside air temperature is detected by the sensor 42, and the outside air temperature becomes 0 ° C. during the heating operation or during the stop.
In order to prevent the drain water accumulated in the second drain pan 28 from freezing and making the rotation of the disk 29 impossible, when the detected temperature of the outside air temperature sensor 42 becomes 0 ° C. or less, Only the plate 29 is rotated to prevent the drain water from freezing.

That is, as shown in FIG. 10, when the operation of the air conditioner is stopped (s1) → when the outside air temperature becomes 0 ° C. or less (temperature detection by the outside air temperature sensor 42) (s2) → for the disk 29 Energize motor 30 (s3) → rotate disk 29 to prevent freezing of drain water (s4) → outside air temperature is 0 ° C
If this is the case (s5), the energization of the motor 30 for the disk 29 is stopped (s6). Thereafter, s2 to s6 are repeated.

The atomizing device 2 according to the first embodiment
2, that is, in the structure shown in FIG.
There are several points to be improved shown in (i) to (iii) below. That is, (i) the atomizing device 22 does not have its own blowing function. Therefore, in order to efficiently discharge the atomized drain water to the outside, it is absolutely necessary to utilize the blowing of the outdoor blowing fan 17. Therefore, while the outdoor fan 17 was stopped (for example, during the defrosting operation), the drain water atomization process could not be performed. (ii) The atomizing ability of the atomizing device 22 largely depends on the size of the atomizing outlet 34. Therefore, the mist outlet 34
If it is not possible to make the size sufficiently large, the atomized drain water scattered in a direction other than the above-described mist outlet 34 is recovered as roughly untreated water again in the second drain pan 28,
The atomization efficiency of the atomizer 22 was poor. (iii) Numerous protrusions 3 provided on the surface of the rotating plate 23
Dust and the like easily adhere to the surface of No. 5, which may lead to a decrease in atomization ability. An atomizing device 22a having improved points (i) to (iii) is shown in FIG.

However, FIG.

Reference numeral 23-1 denotes a blade disposed on the back surface of the atomizer 23a.
The air sucked from the inlet 33-1 is blown toward the mist outlet 34 according to the principle of a centrifugal fan.

Numeral 33 denotes an atomizing chamber, which has a substantially casing shape as a whole, and allows the air to flow to the outlet 34 effectively. Further, the bottom surface of the atomization chamber 33 is inclined toward the DC motor 24 as going from the suction port 33-1 to the outer periphery, and the untreated water flows together with the orifice shape of the suction port 33-1 toward the DC motor side. Prevents overflow. Also, the back surface 23-2 of the atomizer 23a.
The part a is inclined downward in the circumferential direction,
The provision of the ring-shaped projection 23-3 on the circumference is also a shape for preventing water droplets attached to the back surface of the atomizer 23a from being transmitted to the shaft of the DC motor 24 and falling.
In the event that water drops fall along the shaft, a draining ring 24-1 is provided with the E-ring 24-2 positioned on the shaft of the DC motor 24. Even if a ring-shaped depression is formed instead of the ring-shaped projection 23-3, it is possible to similarly prevent a drop of water droplets.

The untreated water 27 finally flows from the drain port 25 provided at the bottom of the atomizing chamber 33 to the second drain pan 28. This drain 2
The shape of No. 5 is a shape obtained by cutting the cylinder smoothly. This is because the tip of the cylinder approaches the bottom of the second drain pan 28 to reduce the sound of water dripping, and the water level of the second drain pan 28 rises. In order to allow untreated water to flow even if it is frozen and frozen in that state,
The second drain pan 28 is opened obliquely upward.

The operation of the air conditioner according to the third embodiment having the above-described configuration will be described with reference to FIGS. 3, 6, 11 and 12 during the heating operation. During the heating operation, if the outdoor heat exchanger 16 acts as an evaporator and the refrigerant evaporation temperature is approximately -1 ° C. or higher, dew is formed and becomes drain water, which is dropped onto the first drain pan 19. The drain water naturally drops through the drain guide 20 to the center of the atomizer 23a rotating at high speed from the drain hole 22-2.
In this embodiment, the drain water dropped on the atomizer 23a rotating at a high speed of about 7500 to 8500 rpm spreads on the surface of the atomizer 23a and is centrifuged to generate the water shown in FIG.
As shown in the figure, the particles come out as small particles in a substantially tangential direction of the atomizer 23a. The ejected particulate water droplets collide with the diffusion plate 22-3 at a high speed (relative speed of about 35 m / sec), and are further broken down into uniform fine particles of about 5 to 10 μm.

On the other hand, by the rotation of the atomizer 23a, the air sucked from the inlet 33-1 flows to the atomizing outlet 34 along the wall surface of the atomizing chamber main body 22a having a substantially casing shape. In FIG. 12, the fine particles are partially sprayed at the position a, more than half at the positions b and c, and almost all at the positions d and e in FIG. 12, depending on the position relative to the wall surface (casing) of the atomizing chamber main body 22a. Water is discharged from the outlet 34 along with the flow of air.

The untreated water 27 re-condensed on the diffuser plate 22-3 and the wall surface of the atomizing chamber main body 22 is collected and directed from the drain port 25 to the second drain pan 28. The untreated water 27 collected in the second drain pan is swept up toward the outdoor heat exchanger 16 by the rotation of the disk 29 directly connected to the scooping motor 30. However, the drain water is collected in the first drain pan 19 so that the drain water does not fall on the outdoor heat exchanger 16, the drain water is collected in the first drain pan 19, and is again dropped from the drain guide 20 to the atomizer 23 a. Circulates untreated water. When the evaporation temperature of the refrigerant becomes lower than or equal to about −1 ° C., frost starts to adhere to the surface of the outdoor heat exchanger 16 and generation of dew stops. When the frost formation exceeds a predetermined amount, the indoor air blower fan 15 and the outdoor air blower fan 17 are stopped by the operation of the protection device such as detection of the temperature of the outdoor heat exchanger, and the defrosting operation is started. Thereby, the frost adhering to the outdoor heat exchanger 16 is melted, becomes defrosted water, collects in the first drain pan 19 at a stroke, and drops onto the atomizer 23a through the drain guide 20. At this time, the outdoor air blowing fan 17 is stopped, but the atomizing device 22a of the third embodiment having its own air blowing function performs the single operation even when the cycle is in the defrosting operation, and improves the efficiency of drain treatment. Is increasing. Hereinafter, the description is omitted because it is the same as that of the first embodiment.

On the other hand, during the cooling operation, as shown in FIGS. 2 and 5, dew generated in the indoor heat exchanger 14 becomes drain water and drops on the drain tray 31 and passes through the drain guide 32. Collected in the second drain pan 28. The drain water becomes water droplets by the rotation of the disk 29 directly connected to the motor 30 and is drawn up to the outdoor heat exchanger 16 acting as a condenser. At this time, the lid member 4
0 is open.

(First Modification) Next, a preferred modification of the drain water treatment apparatus according to the first to third embodiments will be described. First, a first modification will be described with reference to FIGS. In the air conditioner of the first embodiment, FIG.
As shown in FIG. 6 and FIG.
Is disposed in the second drain pan 28, but the heat of the discharge portion is always taken by the drain water. Therefore, the heating capacity may be reduced, and the efficiency may be reduced. Since it is necessary to heat the drain water in order to prevent the drain water from freezing, it is sufficient only when the outside air temperature sensor 42 determines that the outside air temperature is 0 ° C. or less.

Therefore, in the first modified example, as shown in FIG. 14, two refrigerant pipes A and B are provided from the discharge part of the compressor 46, and switching is performed by the two-way valve 27 (or each valve is provided). May be used). The operation of the first modification is shown in FIG.
As shown in (2), only when it is determined that the outside air temperature is 0 ° C. or lower (s12) during the heating operation (s11), the two-way valve is switched to the opening on the pipe A side (s13). If it is determined that the outside air temperature exceeds 1 ° C. in consideration of chattering (s14), the two-way valve is switched to the opening on the pipe B side (s1).
5). However, during cooling, the refrigerant may be passed to the A side to improve the condensation efficiency. In this modification, the discharge high-temperature portion 36 is described, but this is not limited to the refrigerant pipe from the discharge portion of the compressor. It may be taken from a location.

(Second Modification) Next, the second modification is the second modification.
The drain pan 28 is provided with a heater for preventing the drain water from freezing separately from the refrigerant pipe. In other words, to use a part of the refrigerant pipe for drain water heating,
The configuration becomes slightly complicated and the heating capacity may be reduced. Therefore, the heater is provided separately from the refrigerant pipe. As shown in FIG. 16, the operation of the heater of the second modification is such that the drain water heater is energized only when the heating operation is being performed (s21) and the outside air temperature is determined to be 0 ° C. or less (s22). (S23). Then, in order to prevent chattering, if it is determined that the outside air temperature exceeds 1 ° C. (s
24), the energization of the drain water heater is stopped (s25).

(Third Modification) An air conditioner according to a third modification will be described with reference to FIG. FIG. 17A is a cross-sectional view of the air conditioner, and FIG. In the third modification, the two heat exchangers 16a1 and 16a2 of the outdoor heat exchanger 16a in the second embodiment are arranged so as to be substantially V-shaped when viewed from above, and the respective arranged exchangers are arranged. Drain water is supplied between 16a1 and 16a2. In the first embodiment, as shown in FIG. 7, the outdoor heat exchanger 16 is integrated, but in the second embodiment, as shown in FIGS. 8 and 9, the outdoor heat exchanger 16a Consists of two heat exchange units 16a1 and 16a2, and the heat exchange units 16a1 and 16a1
A gap is required between 6a2 to allow the drain water scraped up by the disk 29 to enter. In this case, each of the heat exchange units 1
If 6a1 and 16a2 are arranged in parallel, a space between the outdoor heat exchanger 16a and the outdoor blower fan is required, and the thickness of the product body of the air conditioner increases.

Therefore, in the third modification, the heat exchange portions 16a1 and 16a2 are arranged in a substantially V shape when viewed from above. Accordingly, the gap for the drain water to be lifted up by the disk 29 is sufficient only in the vicinity of the disk 29, and conversely, the drain water is supplied to each of the heat exchange units 16a1 and 16a during cooling.
When it is desired to apply the number 2, it is convenient to dispose it in a substantially V shape as described above. In this manner, the outdoor heat exchanger 16a and the like are arranged without taking up space. Also,
With the above configuration, the outdoor heat exchanger 16
The heat exchange efficiency of (a) is improved and the operation noise is reduced.
That is, the flow of air blown by the outdoor blower fan 17 is
The result is as shown in FIG. Further, since the radiation fins are provided along the thickness direction of the heat exchanger 16 in the outdoor heat exchanger 16a, the flow of the air in the thickness direction is smooth without any resistance. Therefore, according to the configuration of the third modified example, the flow of the blast is smooth, and the blast is well hit by the fins, so that the heat exchange efficiency is improved. In addition, the smooth flow of the air does not generate unnecessary wind noise, so that the operation sound is quiet.

(Fourth Modification) As a fourth modification, a preferred example of the cleaning operation of the rotary atomizers 23, 23a of the atomizing devices 22, 22a will be described with reference to FIG.
During the cooling or dehumidifying season, the atomizers 23, 2
Since 3a is not used, dust and sand are deposited on the stopped atomizers 23, 23a during the cooling season,
May stick. Atomizers 23 and 2 using the above-mentioned fixed matter
If there is an imbalance of 3a, it will be the heating season,
Atomizer 2 that rotates at high speed when operating the air conditioner
3, 23a may cause abnormal vibration or the atomization ability may be reduced. The same applies to the disk 29 for draining water. In order to avoid such a fear, the fourth modified example is used for the atomization for a certain period of time (for example, 10 seconds) in synchronization with the start of the compressor, immediately after starting the operation such as cooling or dehumidification, and simultaneously with the disk 29. The DC motor 24 is driven.
More specifically, as shown in FIG. 18, the operation is first started (s31). If the start operation is a cooling or dehumidification operation (s32), it is determined whether the compressor is energized and started (step S31). s33). When the compressor is started, the DC motor 24 for the atomizers 23 and 23a and the motor 30 for the disk 29 are energized and driven in synchronization therewith (s3).
4). Thereafter, it is determined whether or not 10 seconds have elapsed after the energization (s35), and after 10 seconds, the energization is stopped (s3).
6). Thereby, the atomizers 23 and 23a and the disk 29
It is possible to prevent foreign substances such as dust and sand from adhering to the surface of the device, which is useful for preventing the atomization ability from being reduced during the off-season, abnormal noise, and abnormal vibration.

(Fifth Modification) Next, as a fifth modification,
A preferred example of the freeze prevention operation of the rotary atomizers 23 and 23a during the heating season will be described with reference to FIGS. In the heating season, if water droplets or the like remain on the surfaces of the stopped atomizers 23 and 23a when the outside air temperature is 0 ° C. or less, they are frozen and, depending on the size, are atomized. When the atomizers 23 and 23a are unbalanced, the high-speed atomizers 33 and 23a vibrate or lock abnormally, which may cause a failure of the atomizer DC motor 24.

Therefore, in the fifth modification, the atomizers 23, 2
In order to ensure the prevention of freezing of 3a, when the outside air temperature is equal to or lower than the predetermined temperature, the atomizers 23 and 23a are operated at the predetermined rotation speed instantly after the heating operation is stopped and a predetermined time has elapsed.
More specifically, as in the flow shown in FIG. 19, first, it is determined whether or not the heating operation is being performed (s41). If the heating operation is being performed, it is determined whether or not the outside air temperature is 2 ° C. or lower (s42). The outside air temperature sensor 42 is suitable for detecting the outside air temperature in this case. In addition, in order to prevent icing, it is considered that the detected outside air temperature should be 0 ° C. or less. However, in this modification, in order to ensure safety in consideration of variations and errors of the outside air temperature detection sensor. 2 ° C. or less.

If it is determined that the outside air temperature is 2 ° C. or less,
It is determined whether or not the air conditioner has stopped operating (s4
3). When the operation is stopped, it is determined whether or not 5 minutes have elapsed after the operation was stopped (s44). If five minutes have elapsed after the operation was stopped, it is determined again whether the outside air temperature is 2 ° C. or lower (s45). This temperature determination is for confirming that the anti-icing operation is not performed when the outside air temperature increases after the operation is stopped. Further, the means for detecting the outside air temperature in this case is not limited to the outside air temperature sensor, but can be detected by using the temperature of the outdoor heat exchangers 16 and 16a at the time of stopping the operation of the air conditioner.

If the judgment result is positive and the outside air temperature is 2 ° C. or less, the DC motor 24 of the atomizers 23 and 23a is energized (s46). It stops (s47, s48). As a result, the atomizers 23 and 23a are operated instantaneously and the drain water and the like remaining on the surfaces are shaken off. Next, the counter n is incremented by one, and if the counter n is less than 4, it waits until 5 minutes have elapsed after stopping the energization of the DC motor 24 (s51), and if 5 minutes have elapsed, the process returns to s46, The steps up to s51 are repeated until the counter n reaches 4. Note that the counter n whose counter n has become 4 is cleared (s52). As described above, when the outside air temperature is detected to be 2 ° C. or lower, the outside air temperature is checked after a lapse of a fixed time (for example, 5 minutes) after the main body is stopped, and FIG.
As shown at 0, the DC motor 24 is energized to rotate the atomizer for 0.2 seconds to shake off the drain water. Then 5
A cycle of rotating the atomizers 23 and 23a a plurality of times (4) times is repeated a plurality of times at intervals of minutes and a rotation of 0.2 seconds again, and the drain water is completely shaken off.

As described above, at fixed intervals, only for a short time,
The reason why the atomizing DC motor 24 is not operated is that if the user stops the main body and the mechanical operation (noise) occurs due to the continuous operation of the DC motor 24, the user is given an uneasy feeling that there is a malfunction. It is. The reason for repeating the above operation several times is that after the operation is stopped, the atomizers 23 and 2 are used.
If the atomizers 23 and 23a are operated for a short time after all the dripping of the drain water flowing out on the 3a has run out, depending on the condition of the outside temperature, the dripping of the drain water may stop. During this time, water droplets attached to the atomizing fan surface freeze, and on the other hand, if the atomizers 23 and 23a are operated early and thereafter are not operated, it is not possible to cope with the subsequently dropped drain water. . Therefore, the atomizer 23,
Four repetitions were set at intervals such that the water on the surface of the surface 23a did not freeze, and as a predicted time from when the operation was stopped until the drain water stopped flowing.

(Sixth Modification) As a sixth modification, when the outside air temperature once becomes 0 ° C. or more while the operation is stopped, 0 ° C.
In this case, the atomization motor is operated only once for 0.2 seconds even when the temperature is lower than 0 ° C. and the temperature is detected for a predetermined time (5 minutes) or more. That is, in detail, it is determined whether or not the operation of the air conditioner is stopped as in the flow shown in FIG. 21 (s6).
1) If the operation is stopped, it is determined whether or not the outside air temperature is 0 ° C. or higher (s62). If it is 0 ° C. or higher, it is then determined whether the outside air temperature is lower than 0 ° C. (s63). 0 ° C
If it is less than 0, measurement of the time in the state of less than 0 ° C is started (s64). Next, it is determined whether or not the state in which the outside air temperature is lower than 0 ° C. has continued for 5 minutes or more (s65, s6).
6). If the state in which the outside air temperature is lower than 0 ° C. continues for 5 minutes or more, the DC motor 24 of the atomizers 23 and 23a is energized to rotate the atomizers 23 and 23a (s67).

Next, the time measurement of less than 0 ° C. is completed (s
68). In this case, the measured time is cleared. Next, it is determined whether or not 0.2 seconds have elapsed after the energization of the DC motor 24 (s69). If 0.2 seconds have elapsed, the energization of the DC motor 24 is stopped (s70). If the time during which the outside air temperature is less than 0 ° C. is less than 5 minutes in s65 and s66, the measurement below 0 ° C. is terminated (s7).
1). In this case, the measured time is cleared.

(Seventh Modification) A seventh modification is a modification of the first embodiment.
This protects the lifting motor 30 for 9. That is, at the start of the heating operation, if the outside air temperature and the temperature of the outdoor heat exchanger 16 are 2 ° C. or less, the motor 3
0 and the energization of the atomizer DC motor 24 are delayed for a certain time (15 minutes). However, no delay is made within two hours from the last stop of operation. Specifically, as shown in the flow of FIG. 22, it is determined whether or not the heating operation has been started (s81), and if the operation has been started, it is determined whether or not the outside air temperature is 2 ° C. or lower (s82). If it is 2 ° C. or less, it is determined whether the temperature of the outdoor heat exchanger 16 is 2 ° C. or less (s83). If it is equal to or lower than 2 ° C., it is determined whether or not two hours or more have elapsed since the last operation stop (s84). If two hours or more have elapsed, time measurement is started (s85). If either the outside air temperature or the temperature of the outdoor heat exchanger 16 exceeds 2 ° C., or if the heating operation stop time does not exceed 2 hours, the process ends (s82 to s84). Next, the atomizers 23, 23 are used until the measurement time becomes 15 minutes or more.
a DC motor 24 and motor 3 for lifting disk 29
The energization to 0 is prohibited, and these are stopped (s87).
On the other hand, if the time has reached 15 minutes or more, the time measurement is terminated (s88). In this case, the measurement time can also be cleared.

This seventh modified example is based on drain water freezing.
This is to prevent the lifting motor 30 from being locked. In the first embodiment, since the discharge high-temperature portion 36 of the compressor is provided in the second drain pan 28, the ice around the disk 29 melts for a certain time (within 15 minutes) after the start of operation, and the motor 30 Lock is prevented.

(Eighth Modification) In an eighth modification, the release of the freezing of the drain water can be more accurately grasped in conjunction with each of the above modifications and the water level sensor. If an electrode type water level sensor that detects water by passing a weak direct current (DC) or alternating current (AC) is used, since ice is an insulator, it is determined that there is no water, and power is supplied to the scraping motor 30. Suspension can be extended. For example, the electrodes P1 and P2 are disposed in the second drain pan 28 to such an extent that the electrodes P1 and P2 come into contact with the drain water. Applying a direct current (DC) or alternating current (AC) low voltage between the electrodes P1 and P2 without risk of electric shock to the human body,
The weak current flowing between the electrodes P1 and P2 causes the electrode P1
And a water level sensor for detecting a drain water level from the resistance value. In addition, since ice is an insulator, when the drain water freezes, the resistance value increases, and it can be determined that there is no water. Based on the result of this determination, the period during which energization of the motor 30 is stopped can be extended to protect the motor 30. In the above embodiment, the drain water treatment apparatus is shown as a preferred application example of the atomization apparatus of the present invention. However, the processing target of the atomization apparatus of the present invention is not limited to drain water, and water and various other liquids are used. It can be used for atomization.
