BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically draining condensate generated during the operation of an air conditioner or a dehumidifier to the outside, and more particularly, to pump condensate by gravity of the generated condensate. The present invention relates to an automatic drainage system which allows the condensate to be drained completely with no power and noise by pumping and filling into a siphon tube.

As is well known, an air conditioner is an air conditioner used to properly maintain a room temperature by using a refrigeration cycle, and is widely used throughout the society including a general household.

The refrigeration cycle compresses the low-temperature and low-pressure steam refrigerant into a high-temperature and high-pressure gas in the compressor, and liquefies it by heat dissipation by heat exchange with the outside air in the condenser, and expands the liquefied refrigerant to low-temperature and low pressure in the evaporator. By evaporating by endotherm by heat exchange with bet, indoor air is cooled and cooling is performed.

Accordingly, a large amount of condensed water is generated on the surface of the evaporator due to a sharp drop in the saturated water vapor pressure due to the temperature difference between the evaporator and the condensate, which contaminates the room.

Conventionally, when a certain amount of condensate is collected in a separate container, a method of throwing away the sewer is commonly used, but in this case, it is necessary to pay close attention not to overflow the condensate into the container, but also to inconvenience the condensate collected in the container from time to time.

As a result, in recent years, a method of connecting a drain pipe to a drain pan of an air conditioner and forcing it by a pump is generally used. Although this method can easily drain condensate, the drain pump is continuously operated during operation of the air conditioner. Driven by a problem that increases the indoor unit noise and power consumption.

On the other hand, Republic of Korea Utility Model Registration No. 0213674 discloses the automatic condensate drainage of the air conditioner using the atmospheric pressure. In this technology, when the condensate accumulates to the upper limit of the sump, the filling pump is temporarily operated to fill the siphon tube to start siphoning, and then the siphon action is continued by the level control tank using atmospheric pressure provided at the outlet of the siphon tube. By doing so, the condensate can drain naturally without power.

However, this technology has the advantage of temporarily operating the filling pump only once during the operation of the air conditioner.However, the installation of the water level control tank is very difficult, which makes it difficult to expect accurate construction. There is a high possibility that the siphon action may not be performed smoothly because the level is out of the defined position. In particular, a supplementary pump must be provided to charge the condensate to the siphon, even if only once during operation of the air conditioner.

In addition, Korean Utility Model Registration No. 0329477 and Japanese Patent Application Laid-open No. Hei 10-339465 disclose a technique in which a water level sensor detects an upper limit of condensate in a collecting tank and drains by siphoning while intermittently driving a filling pump. However, these technologies are disadvantageous in terms of noise and power consumption because they have to be operated intermittently and repeatedly, instead of having an installation advantage, and they also have a problem in that they must be equipped with a filling pump to charge condensate to the siphon. .

On the other hand, such a problem of drainage of condensate is not only limited to air conditioners, but also inevitably accompanied by the operation characteristics in the use of a dehumidifier for removing moisture in the air. Therefore, in devices generating condensate, drainage is a significant factor.

The present invention was devised to solve the above-mentioned conventional problems, and the condensate is pumped by the gravity of the condensate collected in the collecting tank and filled into the siphon tube without the additional fill pump and the water level sensor. Its purpose is to provide an automatic drainage system that can discharge completely with no power.

It is effective in improving the reliability, quietness, and ease of use of the dehumidifier and the like.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

1 to 3, the first embodiment of the automatic drainage apparatus according to the present invention is elastically restored upwards in the housing 10 and in the evaporator of, for example, an air conditioner indoor unit (not shown). Reservoir 20 for collecting the generated condensate, siphon pipe 30 for discharging the condensed water filled in the reservoir 20 to the outside by siphon action, and condensate W collected in the reservoir 20 Is filled with a filling space 41 and the filling space 41 is reduced by the weight of the condensate (W) collected in the reservoir 20 to pressurize the condensate (W) in the filling space 41 to siphon pipe ( It consists of a pressure filler 40 to fill in 30).

The housing 10 may be configured in a cylindrical shape having a predetermined depth so that the reservoir 20 can be sufficiently elevated. Inside the housing 10, four vertical guides 12 on a rod are arranged at regular angle intervals near the edge of the bottom and fixedly supported on the inner circumference of the housing 10 through a bracket 13.

Here, although not shown separately, the vertical guide may be composed of a guide groove or a guide protrusion formed directly on the inner circumference of the housing 10, in this case, the guide groove or guide projection on the outer circumference of the reservoir 20 By providing a matching protrusion or channel, the lifting and lowering of the reservoir 20 can be guided.

Such a housing 10 may be installed anywhere inside or outside the air conditioner indoor unit (Ui) as shown in FIGS. 16A and 16B. For example, it may be desirable to install the inside of the indoor unit (Ui) in a new air conditioner. In the case of adopting an air conditioner that is already installed, it may be preferable to install the device outside the indoor unit Ui.

In addition, when installing in the indoor unit Ui, as shown in FIG. 16C, it is also possible to use the lower part itself of the indoor unit Ui as the housing | casing 10. As shown in FIG.

The reservoir 20 has four guide brackets 21 movably coupled to the vertical guides 12 of the housing 10 on the outer circumference thereof. In addition, a compression coil spring 22 is provided in each of the vertical guides 12 of the housing 10 below each of the guide brackets 21 so as to be elastically restored upward.

The elasticity of the compression coil spring 22 causes the empty reservoir 20 to rise to the uppermost side in the housing 10, but a certain amount of condensate W is collected in the reservoir 20 so that the weight of the condensate W is increased. If it is over a certain weight, it is designed to be gradually compressed.

And the center of the bottom of the reservoir 20 is formed with an assembly hole 23 is inserted into the top head 43 of the pressure filler 40 described later.

However, the upper end of the pressure filler 40 is simply fixed to the lower surface of the reservoir 20, or pressurized fillers 70, 80, 90, 100 as shown in Figures 8 to 13 is a separate connection pipe When the connection holes 23 are connected to the reservoir 20 through the 77, 87, 97, and 106, the assembling holes 23 may allow the condensed water W in the reservoir 20 to flow out to the pressurized filler 40. It is replaced by a drain hole of the appropriate size.

The siphon tube 30 is formed in a substantially U shape and passes through or penetrates the wall of the building. The inlet 31 of the siphon tube 30 is located indoors and is connected to the pressure filler 40, the outlet 32 is located at a lower level than the inlet 31 in the outdoors for siphoning, for example, sewage ( G) can enter.

The siphon tube 30 may be made of a conventional hard pipe, but preferably made of a flexible tube having an appropriate length so as to freely establish a path according to the structural condition of the installation place.

Pressurized filler 40 may be configured in a variety of forms, for example, compressible having a suitable filling space 41 therein to allow a certain amount of condensate (W) collected in the reservoir 20 to be introduced It can be configured as a flexible appendix.

In addition, the appendix is made of a flexible bellows pipe 42 for more stable stretching, it is preferable to close the top and bottom of the bellows pipe 42 with a hard head 43 and the base 44, respectively. .

The head 43 is fitted into the assembly hole 23 formed in the bottom of the reservoir 20 to be hermetically fixed, and the head 43 has condensed water W in the reservoir 20 flowing into the filling space 41. A check valve 45 is installed to allow only that. The base 44 is fixed to the bottom of the housing 10 and has a flow path 44a connected to the inlet 31 of the siphon tube 30.

On the other hand, it can be drained enough by only the connection of the base 44 flow path 44a and the siphon tube 30 of the pressure filler 40 in this way, but preferably the lower end and the siphon tube 30 of the reservoir 20 The indoor side of the connection is connected together by a separate flexible connecting pipe 50, and the second check valve 51 to allow only the inflow of condensate (W) at the inlet of the connecting pipe 50 for a smooth drainage You may.

Next, the operation of the first embodiment of the automatic drainage device according to the present invention configured as described above will be described with reference to FIGS. 5A to 5D.

First, FIG. 5A shows, for example, that the air conditioner is not in operation. At this time, since there is no condensate in the reservoir 20, the reservoir 20 is positioned at the top of the housing 10 by the compression coil spring 22. Done. Therefore, the pressure filler 40 is fully opened to secure a sufficient size of the filling space 41 therein, and the pressure filler 40 and the inside of the siphon tube 30 become empty.

In this state, when the air conditioner is operated, condensate (W) generated on the surface of the evaporator is continuously introduced into the reservoir 20 through the condensate drain port P installed in the drain pan (not shown) of the air conditioner. .

Then, a part of the condensed water (W) collected in the reservoir 20 is filled with a fill space (through the check valve 45 provided in the head 43 of the pressure filler 40 located in the lower portion of the reservoir 20) 41), and thus the filling space 41 is filled with condensate (W) and the siphon pipe 30 is also filled with the condensate (W) at the same level as the reservoir 20.

Subsequently, as shown in FIG. 5B, when the condensed water W is filled in the reservoir 20 at a predetermined level or more and the weight thereof is greater than the elasticity of the compression coil spring 22, the reservoir 20 is compressed coil spring 22. ) And begins to descend along the vertical guide (12).

Then, the pressure filler 40 located in the lower portion of the reservoir 20 is pressed by the reservoir 20 and starts to crush. Then, the pressure in the pressurized filler 40 increases, so that the check valve 45 and the second check valve 51 are closed, so that the condensed water W in the pressurized filler 40 is siphoned. It is pushed to

Then, if the reservoir 20 is further lowered by the weight of the condensate (W) that is continuously introduced as shown in Figure 5c the bellows pipe 42 of the pressure filler 40 is gradually compressed to completely shrink the As the volume of the filling space 41 is greatly reduced, the condensed water W filled therein is pushed into the siphon tube 30 to completely fill the siphon tube 30.

As such, when the siphon tube 30 is filled with condensed water (W) and discharge is started from the outlet 32 to the sewer (G), the siphon action is started, and the pressure of the siphon tube 30 is the reservoir 20. Since the pressure is less than the internal pressure, the check valve 45 closing the flow path 44a of the base 44 and the second check valve 51 closing the inlet of the connecting pipe 50 are opened again, and the water reservoir 20 The condensate (W) inside the tank continues to drain automatically to the outside with no power and no noise.

At this time, even while the condensed water (W) in the reservoir 20 is discharged by the siphon action, the condensed water (W) continues to flow into the reservoir 20 from the evaporator, but because the discharge amount is relatively larger than the inflow amount of the reservoir 20 ), The water level will gradually decrease.

Therefore, after the siphoning is started, as shown in FIG. 5D, the weight of the reservoir 20 gradually decreases as the water level decreases, and then the compression coil spring 22 of each of the vertical guides 12 is reduced. By the resilient elasticity, the reservoir 20 is raised again as shown in FIG. 5A and returned to the initial position.

Accordingly, the pressure filler 40, which was completely compressed, is unfolded again by the rising reservoir 20. Then, after the condensate (W) in the reservoir 20 is mostly drained and the reservoir 20 is fully raised, air is introduced into the siphon tube 30 to stop the siphon action, and thus drainage is stopped. The interior of the tube 30 is again empty.

In this state, when the water level of the condensate (W) introduced into the reservoir 20 after a certain time has risen again by a predetermined level or more, the reservoir 20 is again caused by the weight of the condensate (W) as described above. By lowering and reducing the pressure filler 40 to restart the siphon action, and thus repeatedly performing such an operation while the air conditioner is operating, it is possible to automatically discharge the condensate (W) completely silent and silent.

On the other hand, Figure 6 schematically shows a second embodiment of the automatic drainage device of the present invention.

This embodiment has a cylinder 61 in which the pressure filler 60 is connected to the inlet 31 of the siphon tube 30 and the check valve 64 in the configuration of the first embodiment described above. Both ends are respectively provided on the upper surface of the piston 62 and the bottom surface of the reservoir 20 having a piston 62 coupled thereinto and a rising and lowering passage 65 for communicating the reservoir 20 and the check valve 64. It consists of a piston rod 63 is fixed.

The cylinder 61 is fixed to the bottom center of the housing 10 at regular intervals from the reservoir 20 for the lifting of the reservoir 20, and the piston rod 63 is an assembling hole of the reservoir 20. A head 66 inserted into the top 23 is provided at the upper end to be hermetically fixed to the reservoir 20.

Next, the operation of the second embodiment configured as described above will be described with reference to Figs. 7A to 7D.

First, FIG. 7A shows that the reservoir 20 is empty because the air conditioner does not operate, and the reservoir 20 is located at the top of the housing 10. Accordingly, the piston 62 is connected to the cylinder 61. FIG. Located in the upper portion, the filling space 61a of the cylinder 61 is enlarged as much as possible.

In this state, when the air conditioner is operated and the condensate (W) continues to flow into the reservoir 20, a part of the condensate (W) in the reservoir 20 passes through the flow path 65 of the piston rod 63 and the check valve ( Condensed water (W) is introduced into the filling space (61a) of the cylinder 61 through the 64 to fill the filling space (61a) and at the same level as the reservoir 20 to the indoor side of the siphon tube (30). Will be filled.

Then, when the condensate (W) is continuously introduced to a predetermined level or more and the weight of the reservoir 20 is greater than the elasticity of the compression coil spring 22, as shown in Figure 7b the reservoir 20 is The compression coil spring 22 is lowered along the vertical guide 12 while compressing.

Then, the piston 62 starts to descend at the same time by the piston rod 63 fixed to the reservoir 20, and accordingly, the pressure in the filling space 61a of the cylinder 61 is increased to check valve 64 and As the second check valve 51 is closed, the condensed water W in the filling space 61a is pushed into the siphon tube 30.

Then, when the condensate (W) is filled in the reservoir 20, as shown in Figure 7c, the reservoir 20 is further lowered so that the piston 62 reaches the bottom of the cylinder 61 to fill the filling space ( By minimizing 61a), the condensed water W in the filling space 61a is pushed into the siphon tube 30 to completely fill the siphon tube 30.

Accordingly, as the siphon action is started, the check valve and the second check valve 64 and 51 are opened again, so that the condensed water W in the reservoir 20 is automatically drained to the outside with no power and noise.

When the condensate (W) in the reservoir 20 is discharged by the siphon action, and the water level of the reservoir 20 is gradually lowered, and the weight of the reservoir 20 is reduced, the compression coil spring 22 as shown in FIG. 7D. By the resilience of the resilience of the reservoir 20 is raised to the initial position, the piston 62 is raised again to expand the filling space (61a) of the cylinder (61).

After the condensate (W) in the reservoir 20 is drained in this way and the reservoir 20 is completely raised, air is introduced into the siphon tube 30 to stop the siphon operation, and the predetermined time elapses again. When the water level of the condensate (W) introduced into the water tank 20 rises by a certain level or more, as described above, the water reservoir 20 again descends by the weight of the condensate (W) to restart the siphon action to condense water (W). Will be discharged automatically.

One end of the cylinder 102 is provided with a check valve 104 to allow only condensate to be introduced therein, and the piston 103 in a direction in which the filling space 101 is reduced between the other end of the cylinder 102 and the piston 103. Compression coil spring 105 for elastically restoring is interposed.

The wire 107 is provided with a guide pulley 108 under the central portion of the reservoir 20 so that the pressurizer 100 can be stretched horizontally by the reservoir 20 which moves up and down vertically to move substantially L-shaped. Has a path.

In the sixth exemplary embodiment of the present invention, when the condensate is introduced into the reservoir 20 and the reservoir 20 is lowered, the piston 103 is applied to the restoration elasticity of the compression coil spring 105 as opposed to the fourth embodiment. The condensed water is compressed and filled in the siphon tube 30 while being restored in the direction of reducing the water filling space 101. Accordingly, the condensed water in the reservoir 20 is drained by the siphoning action so that the reservoir 20 rises. As the piston 107 is pulled, the piston 103 moves in the expansion direction of the filling space 101.

14 and 15 schematically show a seventh embodiment of the automatic drainage system according to the present invention.

This embodiment is a siphon retainer which prevents the siphon action initiated on the outside of the siphon tube 30 from being dissipated to the drainage of the condensate water W in the above-described embodiments, for example, the first embodiment described above. 110 is further provided.

To this end, the siphon tube 30 has an inlet 31 which is accommodated in the housing 10 and the outlet 32a has a substantially U-shaped first siphon 30a fitted in a predetermined depth at the top of the siphon retainer 110. , The inlet 31a is fitted at the lower portion of the siphon retainer 110 so that the inlet 31a is at a level higher than the outlet 32a of the first siphon 30a and the outlet 32 is the inlet 31 of the first siphon 30a. The second siphon 30b is located at a lower level.

The siphon retainer 110 has an empty cylinder inside, and has a vent hole 111 on the upper surface so that atmospheric pressure acts therein. The siphon retainer 110 may be inserted long enough to overlap the outlet 32a of the first siphon 30a and the inlet 31a of the second siphon 30b with each other. It is preferable to configure the inlet and outlet guide tubes 112 and 113 in which the front ends overlap each other in the opposite direction, and couple the first and second siphons 30a and 30b to them, respectively.

The siphon retainer 110 is located at the same level as the housing 10 located indoors (or inside an air conditioner, etc.).

In the seventh embodiment of this configuration, the condensate water level in the pressure filler 40 after the siphon action is started is the inlet 31a of the second siphon 30b, that is, the outlet guide tube of the siphon retainer 110. After being drained to the same level as the tip of 113, the vent hole 111 formed in the upper surface of the siphon retainer 110 causes the atmospheric pressure to act on the water surface in the siphon retainer 110, and it is no longer drained. The condensate W is filled in the first siphon 30a.

Therefore, even if the drainage is interrupted, the siphon action is not extinguished and the state is temporarily stopped. After that, when the water level in the reservoir 20 rises, the siphon action is automatically restarted without recharging by the pressure filler 40. Will proceed.

Therefore, when the air conditioner is first operated, the pressure filler 40 is operated only once, and afterwards, a siphon action occurs automatically according to the inflow of condensate (W) to drain the condensate (W).

As described above, according to the automatic drainage device according to the present invention, the water collected in the reservoir is automatically pumped by its weight and filled in the siphon tube without having a separate filling pump and a water level sensor as in the related art. As a result, the water can be discharged completely without noise and noise.

Therefore, the present invention has a very excellent effect, which greatly contributes to the improvement of reliability, quietness, and ease of use, in particular, of equipment in which condensate is generated during operation such as an air conditioner or a dehumidifier.
