Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner drain treatment device for atomizing drain water generated in an evaporator of an air conditioner such as a spot cooler with an ultrasonic atomizer.

[0002]

2. Description of the Related Art As a drain treatment device of an air conditioner for atomizing drain water generated in an evaporator of an air conditioner with an ultrasonic atomizer, there is one disclosed in Japanese Utility Model Laid-Open No. 57-21942. As shown in FIG. 17, the drain water generated in the evaporator 1 is stored in the water tank 2, and the vibrator 3 of the ultrasonic atomizer provided in the water tank 2 is vibrated to atomize the drain water. The atomized drain water is sprayed to the inside of the condenser 5 by the blower fan 4 inside the condenser 5, thereby cooling the condenser 5 and treating the drain water.

[0003]

Meanwhile, in the above-mentioned structure, since the atomized drain water is sprayed inside the condenser, the blower fan and the fan motor inside the condenser and the Since water droplets adhere to the surrounding area, it was necessary to apply waterproofing and anticorrosion treatment. In order to solve this, the present applicant discloses in Japanese Patent Application No. 5-48256 that drain water atomized by an ultrasonic atomizer is discharged to the outside through a discharge pipe without being sprayed on the condenser. However, although the drain water is prevented from adhering, the condenser is not cooled by the drain water, so that there remains a problem that the cooling capacity of the air conditioner is inferior.

The present invention has been made in view of the above problems. By changing the spraying direction of drain water to the condenser, a high cooling capacity can be maintained, and a waterproof or rust preventive treatment is unnecessary. An object of the present invention is to provide a drain treatment device for an air conditioner in which drain water is treated efficiently.

[0005]

In order to achieve the above object, the present invention has an ultrasonic vibrator for drain water generated in an evaporator provided in a case of an air conditioner. In a drain treatment device of an air conditioner for atomizing with an ultrasonic atomizer, a condenser provided in the case, and a blower fan for the condenser provided inside the case with respect to the condenser. An exhaust passage for discharging the drain water introduced into the case through the condenser to the outside by the blower fan for the condenser, and a blower fan for the evaporator provided inside the case with respect to the evaporator A cool air blowing duct that blows out the cooling air introduced into the case through the evaporator to the outside by the blower fan for the evaporator; and a cool air blowing duct that blows the drain water by the blower fan for the evaporator. It is an arrangement that includes a lead-out passage to derive.

According to a second aspect of the present invention, a water pump for supplying the drain water to the outside of the condenser is provided. According to a third aspect of the present invention, an outer duct for leading out the drain water is provided on the outer circumference of the cool air blowing duct or an inner duct for leading out only the cooling air.

According to a fourth aspect of the present invention, a cylindrical guide is provided in the liquid above the ultrasonic vibrator so as to project a predetermined gap and project above the liquid surface.

[0008]

According to the means of claim 1, part of the drain water atomized by the ultrasonic atomizer is introduced into the case from the outside of the condenser together with the outside air by the blower fan for the condenser. , In this case, since the condenser is cooled by the drain water, the air conditioner maintains a high cooling capacity, and the drain water is heated by the condenser and introduced into the case in an evaporated state, and then in the case. Is exhausted to the outside through the exhaust passage.

On the other hand, a part of the atomized drain water is guided to the cold air blowing duct through the outlet passage by the blowing fan for the evaporator and mixed with the cold air sent from the evaporator to the cold air blowing duct to become humidified cold air. Since it is blown out to the outside from the cold air blowing duct, the cooling capacity is improved by humidification, and the drain water is efficiently discharged to the outside through both the exhaust passage and the outlet passage.

According to the second aspect of the present invention, since the drain water can be sufficiently supplied to the outside of the condenser by the water pump, the condenser is sufficiently cooled and the drain water treatment capacity is enhanced. . According to the means of claim 3, the humidified cooling air led to the cold air blowing duct or the cooling air led to the inner duct is cooled by the humidified air of the drain water led to the outer duct to remove ambient air in the vicinity of the outlet. Since it is entrained and diffused, the temperature drop due to evaporation of water droplets is promoted, so that the range of the cooling effect is expanded and, at the same time, it is led to the cool air blowing duct or the inner duct by the side flow effect of the humidified air led to the outer duct. The reachability of the temperature and speed of the cooling air is improved.

According to the fourth aspect of the invention, the diffusion damping of the radiation pressure generated in the liquid by the operation of the ultrasonic transducer is suppressed by the portion of the guide in the liquid, and the liquid surface generated by the collision of water droplets is suppressed. Since the turbulence is suppressed by the portion of the guide protruding above the liquid surface, atomization of drain water is promoted.

A drain pan 17 that receives drain water generated in the evaporator 13 is provided below the evaporator 13, and the drain water received by the drain pan 17 is provided below the case 11 via a drain hose 18. It is led to the water tank 19. The water tank 19 is provided with an ultrasonic atomizer 20 having an ultrasonic vibrator 20 a that ultrasonically agitates the drain water in the water tank 19 and the drain water in the water tank 19 is provided.

The condenser 1 above the water tank 19
An inlet pipe 22 for guiding a part of the atomized drain water generated in the water tank 19 to the outside of the condenser 12 is provided on the second side, and a part of the drain water atomized by the condenser blower fan 14 is provided. Flows from the introduction pipe 22 as indicated by an arrow A,
An exhaust passage 23 is provided for discharging the atomized drain water introduced from the condenser 12 into the case 11 together with the outside air indicated by the arrow B to the outside of the case 11.

The evaporator 1 located above the water tank 19
A lead-out path 25 is provided on the third side for guiding a part of the atomized drain water generated in the water tank 19 to the cool air blowing duct 24 as shown by an arrow D. In addition, 26 is an air conditioner 10.
It is a driving switch. Next, regarding the above embodiment,
The operation will be described. In FIG. 1, the operation switch 26
When the power is turned on, a control circuit (not shown) is activated to energize the fan motor 16, and the fan motor 16 rotates. Therefore, the condenser blower fan 14 and the evaporator blower fan 15
As the compressor rotates, the compressor operates, so that the operation of the refrigeration cycle starts.

Therefore, the outside air indicated by the arrow B is introduced into the condenser 12, is discharged into the outside air of the case 11 through the exhaust passage 23, and the air is introduced into the evaporator 13 to be cooled by the evaporator 13. The generated air flows as shown by arrow C, and cool air is blown out from the cool air blowing duct 24. In the above operation process, water in the air sucked in the evaporator 13 is cooled and condensed water (drain water) is generated. The generated drain water is received by the drain pan 17 and passed through the drain hose 18. And is led into the water tank 19. Water tank 19
When the water level inside the drain water exceeds a set value, it is detected by the water level detector 21, the control circuit operates, and the ultrasonic atomizer 20 operates, so atomization of the drain water in the water tank 19 starts. .

Here, a part of the atomized drain water in the water tank 19 flows through the introduction pipe 22 as shown by the arrow A, and is guided to the outside of the condenser 12 together with the outside air shown by the arrow B. Then, it is introduced into the case 11 through the condenser 12,
In that case, since the condenser 12 is cooled by the drain water,
The air conditioner 10 maintains a high cooling capacity, and the drain water is heated by the condenser 12 to evaporate and become a gas state, which is introduced into the case 11 and discharged to the outside of the case 11 through the exhaust path 23. Therefore, water droplets are prevented from adhering to the condenser blower fan 14 and the fan motor 16 in the case 11.

On the other hand, a part of the atomized drain water in the water tank 19 flows through the outlet passage 25 as shown by the arrow D and is guided to the cold air blowing duct 24, so that it is mixed with the cold air shown by the arrow C. However, since it becomes humidified cold air and is blown out from the cold air blowing duct 24, the atomized drain water in the water tank 19 is efficiently discharged to the outside of the case 11 from the discharge passage 25 and the exhaust passage 23 described above. To be done.

[Second Embodiment] FIG. 2 is a schematic sectional view showing a second embodiment of the present invention. The difference from the first embodiment of FIG. 1 is that instead of using the suction force of the condenser blower fan 14 to supply the drain water to the condenser 12, a water pump 30 is provided in the water tank 19 and the water tank 19 is provided. The drain water inside is drawn up by the water pump 30 and is supplied to the outside of the condenser 12 through the supply pipe 31.

According to the second embodiment, since the drain water in the water tank 19 is supplied to the outside of the condenser 12 by the water pump 30 by a necessary amount, the condenser 12 is drained as compared with the first embodiment. As well as being sufficiently cooled by water, the drain water treatment capacity is also increased. [Third Embodiment] FIG. 3 is a schematic sectional view showing a third embodiment of the present invention. The difference from the first embodiment of FIG. 1 is that the cold air blowing duct 24a is a double duct in which an inner duct 27 and an outer duct 28 surrounding the inner duct 27 are divided, and the inner duct 27 is cooled by the evaporator 13. Only the cooling air shown by the arrow C is allowed to flow, and only the humidified air of the drain water shown by the arrow D flowing through the outlet path 25 is separately passed through the outer duct 28.

According to the third embodiment, the cooling air indicated by the arrow C and the humidified air indicated by the arrow D do not mix up to the outlet of the cold air outlet duct 24a. Therefore, the humidified air indicated by the arrow D causes ambient air to flow around the outlet. Since it is entrained and diffused and the temperature drop due to evaporation of water droplets is promoted, the range of the cooling effect is expanded as compared with the first and second embodiments, and the humid air (secondary flow) flowing through the outer duct 28 is increased. Inner duct 27 due to side flow effect
Since the attenuation of the velocity of the cooling air (main flow) flowing through is reduced, the arrival of the temperature and velocity of the main flow is improved.

[Fourth Embodiment] FIG. 4 is a schematic sectional view showing a fourth embodiment of the present invention. Similar to the third embodiment of FIG. 3, the cold air blowing duct is a double duct, but the outer duct 28 is provided in the vicinity of the blowing port of the cold air blowing duct 24 for leading out the humidified cold air. Third of FIG.
A further difference from the embodiment is that the auxiliary water tank 32 is provided above the case 11, and the ultrasonic atomizer 20 having the ultrasonic transducer 20a is separately provided in the auxiliary water tank 32,
By supplying the drain water in the water tank 19 to the outside of the condenser 12 and the auxiliary water tank 32 by the water pump 30 via the supply pipe 31, the drain water atomized in the auxiliary water tank 32 is supplied to the flexible hose 33. It is configured to be guided to the outer duct 28 via.

According to the fourth embodiment, since a source for atomizing the drain water is separately provided in the vicinity of the outer duct 28 for leading the humidified air of the drain water, the outer duct is different from the third embodiment. Since 28 can be shortened, the amount of water droplets adhering to the outer duct 28 is reduced, and since humidified cool air flows through the cool air blowing duct 24 corresponding to the inner duct, the humidifying and cooling effect is further improved.

[Fifth Embodiment] FIG. 5 is a schematic sectional view showing a fifth embodiment of the present invention. The difference from the fourth embodiment of FIG. 4 is that the ultrasonic atomizer 20 having the ultrasonic vibrator 20a for atomizing the drain water in the water tank 19 and the atomized drain water are led to the cold air blowing duct 24. The derivation path 25 is removed.

According to the fifth embodiment, the ultrasonic atomizer 20 for atomizing the drain water in the water tank 19 and the discharge passage 25 for discharging the atomized drain water to the cold air blowing duct 24 are removed. Therefore, as compared with the fourth embodiment, the cooling air flowing through the inner duct 27 is not humidified, so that the humidification cooling effect is reduced and the drain water throughput is also reduced, but the structure of the air conditioner is greatly simplified. .

[Sixth Embodiment] FIG. 6 is a schematic sectional view showing a sixth embodiment of the present invention. The sixth embodiment is the fourth embodiment of FIG.

Coarse water droplets centrifugally separated from the water tank 19
Returned to. As a result, minute water droplets having a high evaporation rate are discharged to the discharge path 25, so that the cooling effect of the humidified cold air blown from the cold air blowing duct 24 is enhanced.

The centrifugal separation of atomized drain water has been described in the case of being applied to the fourth embodiment shown in FIG. 4, but it is applicable to the method of extracting atomized drain water to the outlet path. can do. FIG. 7 shows the centrifugal separation result by the centrifugal separator 40 of atomized drain water.
As shown in FIG. 7, the average particle size of the water droplets before separation is about 20 microns, whereas the average particle size of the water drops after separation is as small as about 5 microns.

FIG. 8 shows a second embodiment in which the drain water is not used for cooling (a), the condenser 12 is cooled by the drain water using the water pump 30, and the cold air is humidified by the atomized drain water. The example (b) and the example of the fourth example in which the humidification substream of drain water is caused to flow through the outer duct 28 provided near the outlet of the cold air blowout duct 24 in the second example ( C) and the temperature of the cold air blown out from the cold air blowout port for the sixth embodiment (d) in which the centrifugal separator 40 is provided at the suction port of the outlet passage 25 in the fourth embodiment Is the result of a comparative test.

As is apparent from FIG. 8, (b) condenser cooling and cold air humidification using drain water, and (c) humidification sub-flow in which the humid air using drain water is flown to the outer duct of the cold air blowing duct. It has been found that the flow has a particularly large cooling effect. [Seventh Embodiment] FIG. 9 is a schematic sectional view showing a seventh embodiment of the present invention. The seventh embodiment is different from the second embodiment in FIG. 2 in that, for example, three ultrasonic transducers 20a are provided, and a temperature sensor 51 and a discharge path 2 are provided near the suction port of the evaporator 13.
5 is provided with a suction fan 52 near the suction port, and three ultrasonic transducers 20 are provided according to the temperature detected by the temperature sensor 51.
A control device 100 for selectively operating a is provided.

The controller 100, as shown in FIG.
Relays 101, 102, 103 led from a power source, their contacts 101a, 102a, 103a, and control circuit 11
0, the operation switch 26 and the temperature sensor 51 are connected to the control circuit 110, and each relay contact 10
1a, 102a, 103a are ultrasonic transducers 2
0a to constitute an electric circuit.

When the temperature detected by the temperature sensor 51 is, for example, 35 ° C. or lower, the control circuit 110 turns on only the relay 101 to activate one ultrasonic transducer 20a and detect the operation. Temperature is, for example, 35-40
In the case of ° C, the control circuit 110 controls the relays 101, 1
When 02 is turned on and the two ultrasonic transducers 20a are activated, and the detected temperature is, for example, 40 ° C. or higher, the three ultrasonic transducers 20a whose relays 101, 102, 103 are turned on by the control circuit 110 Operate.

Therefore, the humidification amount is controlled to increase as the ambient temperature increases. The suction fan 52 that guides the atomized drain water to the discharge passage 25 may be operated at a constant rotation speed, or may be operated by changing the rotation speed according to the humidification amount. FIG. 11 qualitatively shows the superiority and inferiority of the cooling feeling and the comfort feeling between the conventional one in which the humidification amount is constant with respect to the ambient temperature and the one in the present invention in which the humidification amount is increased as the ambient temperature rises. For comparison, the test shows the average of the results of the investigation of three people regarding the feeling of cooling and the feeling of comfort at a place 1 m away from the cool air outlet of the air conditioner. As is clear from FIG. 11, the cooling feeling and the comfort feeling are both excellent in the present invention in which the humidification amount is increased with the increase in the ambient temperature.

Regarding the control of the amount of humidification according to the ambient temperature, the case where it is applied to the second embodiment of FIG. 2 has been described, or if it is the method of discharging atomized drain water to the discharge path, it is applied. can do.

When the drain water passes through the water purifier 60, bacteria, algae, red rust, etc. contained in the drain water are filtered by the hollow fiber membrane, so the purified drain water is stored in the water tank 1.
It is stored in 9.

Regarding the installation of the water purifier 60 made of a hollow fiber membrane, the case of applying the second embodiment of FIG. 2 was described, but if there is a drain hose for guiding the drain water generated in the evaporator, Can be applied, for example. [Ninth Embodiment] FIG. 13 is a schematic sectional view showing a ninth embodiment of the present invention. In the ninth embodiment, a cotton antibacterial filter 61a shown in FIG. 13 (A) or a solid antibacterial filter 61b shown in FIG. 13 (B) is provided in the water tank 19 of the second embodiment shown in FIG.

Further, it is desirable to use the antibacterial filter 61a or 61b in combination with the above-described water purifier 60 from the viewpoint of sufficiently purifying drain water. [Tenth Embodiment] FIG. 14 is a schematic sectional view showing a tenth embodiment of the present invention. The tenth embodiment is the same as the first embodiment shown in FIG. 1 except that the drain water liquid above the ultrasonic transducer 20a has a predetermined gap L and is projected from the liquid surface to the liquid surface. The cylindrical guide 70 is provided.

According to the tenth embodiment, the horn portion 70a of the guide 70 in the liquid of the drain water is the ultrasonic transducer 20.
Diffusion attenuation of the radiation pressure generated in the liquid by the operation of a is suppressed, thereby maintaining a high radiation pressure, and the separator portion 70b of the guide 70 protruding above the liquid surface causes the disturbance of the liquid surface caused by the collision of water droplets. And stabilizes the liquid surface, thereby promoting atomization of drain water. In order to promote atomization, the gap L is 5
It has been found from experiments that the diameter is preferably around mm and the inner diameter d of the guide 70 is preferably around 24 mm.

FIG. 15 shows the atomization amounts of the conventional one without the guide 70, the comparative one with only the separator portion 70b, and the one with the present invention having the horn portion 70a and the separator portion 70b. It is a comparison. As is clear from the figure, in the present invention compared with the conventional one, the synergistic effect of the high radiation pressure by the horn portion 70a and the stability of the liquid surface by the separator portion 70b promotes atomization of drain water, The ability to atomize drain water is greatly improved.

The installation of the guide 70 for improving the atomization capacity of the drain water has been described in the case of being applied to the first embodiment of FIG. 1, but the drain water in the water tank 19 is changed by the ultrasonic vibrator 20a. Any method of ultrasonic atomizing can be applied. [Eleventh Embodiment] FIG. 16 is a schematic sectional view showing an eleventh embodiment of the present invention.

It should be noted that the installation of the ultrasonic vibrator 80 for atomizing or scattering water droplets adhering to the surface of the evaporator 13 and the strong water repellent treatment 81 of the surface of the evaporator 13 are carried out other than the first embodiment of FIG. The examples can also be applied to all.

In the embodiment described above, the condenser blower fan 14 and the evaporator blower fan 15 are rotationally driven by one fan motor 16, but each blower fan 14 and 15 is a dedicated fan motor. By rotating, the blower fans 14 and 15 may be rotated at different required rotation speeds. Further, in order to prevent the empty operation of the ultrasonic atomizer 20, when the water level of the drain water in the water tank 19 is below a set value, the operation of the ultrasonic atomizer 20 is stopped, If there is no problem, it is not necessary to provide an empty operation prevention mechanism for the ultrasonic atomization 20.
