Siphon actual condition prevention structure of air conditioner condensate multiple handling system

The present invention relates to a siphon phenomenon prevention structure of an air condensate condensate water treatment system improved to prevent the siphon phenomenon that all the condensate from the sump is sucked out even when the drain pump is stopped in draining the condensate generated from the air conditioner.

In general, since condensate is inevitably generated in the air conditioner, the condensate is drained using a drain pump, and the drain pump has a water collecting tank (water bucket) for collecting condensate discharged from the air conditioner.

Therefore, although the discharge hose is connected to the drain or the drain from the sump to the outside to discharge the condensed water at a position lower than the drain pan part of the air conditioner indoor unit, the discharge part is usually installed at the end of the discharge hose. Mostly.

In this case, when the drain pump is started and stopped, a siphon phenomenon occurs in which all condensed water remaining in the sump of the drain pump is sucked out by gravity.

The siphon phenomenon is a phenomenon in which the pressure generated by the product of the pressure of the upper portion of the discharge part of the discharge hose and the pressure generated by the product of the liquid level and the specific gravity correspond to the head pressure. The operation of the drain pump is stopped by the siphon phenomenon. Even though the condensate remaining in the sump is sucked out along the discharge hose, a 'click' sound is generated.

In addition, the drain pump for discharging the air conditioner condensate is operated repeatedly when the water level of the sump is raised and stopped when the water level is lowered. Is generated repeatedly.

In particular, the sound caused by the siphon phenomenon is caused by the noise pollution stressed, and it is pointed out as a serious problem that further increases the stress at night to sleep.

In order to prevent the sound caused by the siphon phenomenon, the discharge end of the discharge hose should be installed at a position higher than the air conditioner drain pan, or the sump outlet should be shut off at the same time that the drainage pump is stopped. There is a problem that is difficult to solve in reality.

It is installed by the installers in the case of air conditioner, where the condition of the air conditioner installation site is a structure that is difficult to install the end discharge part of the discharge hose at the position higher than the water level of the air conditioner drain pan part, or the builders do not construct it properly as described above. This is because the drainage pump is operated and stopped from time to time, and it is practically impossible for the air conditioner to shut off the outlet every time the pump is placed.

Therefore, when the drain pump is operated and stopped from time to time, the sound generated by the siphon phenomenon can not be prevented from time to time, thereby acting as a factor causing stress.

And the drain pump is to serve to cool the pump by remaining water (condensed water) to some extent even if the operation is stopped and to improve the lubricity of the internal piston.

However, as the condensed water in the drain pump is drained out by the siphon phenomenon, the pump is not operated as the coolant and the lubricant as it is operated every time without any water in the pump. It is caused.

The present invention provides an improved siphon phenomenon prevention structure of an air conditioner condensate drainage system to prevent the siphon phenomenon in which all the condensate in the drain pump is sucked out even when the drain pump is stopped in draining the condensate generated from the air conditioner. I want to do that.

Another object of the present invention is to provide a siphon phenomenon prevention structure in which the means for preventing the siphon phenomenon is simple and easy to install.

The present invention is to forcibly drain the condensed water of the air conditioner by the drain pump and the discharge hose; To have a rising vertical hose portion disposed in the upper direction from the drain pump, a rising horizontal hose portion disposed to extend in the horizontal direction from the rising vertical hose portion and a falling vertical hose portion to be lowered downward from the rising horizontal hose portion A discharge hose to be piped; It is characterized in that it comprises a siphon prevention means is installed in the middle of the rising horizontal hose portion and the external air flows into the rising horizontal hose portion when the drainage pump is stopped.

The siphon preventing means may include a fluid pipe part having a hose connection part connected to the middle portion of the rising horizontal hose part, and a fluid passage hole having a fluid inlet and a fluid outlet, and an air passage hole communicating with the fluid passage hole. It is characterized in that it is configured to have an air pipe portion protruding in a right angle in the middle, and an air opening and closing portion to open and close the air inlet hole provided in the air passage hole upper portion.

The air opening and closing portion, the air inlet pipe having a support jaw portion and the air passage groove portion provided in a plurality at equal intervals in the circumferential direction on the upper portion of the air passage hole, the air inlet hole having a close contact portion in the air inlet hole lower portion And, a packing moving hole formed between the air passage groove portion and the close fitting jaw portion, and a packing member for opening and closing an air inlet hole in the packing moving hole, wherein the packing member is rubber. do.

The invention devises a siphon phenomenon because the siphon action force that causes the condensate to be sucked out of the siphon prevention means when the drainage pump is stopped is blocked at the rising horizontal hose part, so that the condensate in the drainage pump cannot be sucked out. There is an effect that no noise is generated at all.

In addition, the noise caused by the siphon phenomenon is not generated by the stress does not provide a significant effect to improve the product reliability.

In addition, since the siphon prevention means is simple and cost increase is not caused, it provides an air conditioner condensate drainage treatment system that can be installed without worrying about the installation position of the discharging end of the discharge hose. There is an effect that the improvement can be planned.

The present invention will be described in more detail based on the attached preferred embodiments as follows.

Figure 1 shows an air conditioner condensate drainage structure according to the present invention, Figure 2 is a longitudinal cross-sectional view of the siphon preventing means, Figure 3 shows a main perspective view of the siphon preventing means.

Referring to FIG. 1, in the present invention, the condensate water w discharged from the drain pan part 11 of the air conditioner 10 is collected in the sump 21 of the drain pump 20.

When the condensate (w) is collected in the sump (21) and reaches the top dead center level, the drainage pump (20) is automatically operated and pumped to drain the condensate (w) along the discharge hose (30). .

In addition, when the water level of the condensate (w) of the sump 21 is lowered to reach the bottom dead center level according to the pumping operation of the drainage pump 20, the drainage pump 20 is automatically stopped to operate the pumping operation. As it is, the drain pump 20 to be pumped as described above is already known, so detailed drawings and description will be omitted.

Therefore, the present invention allows the discharge hose 30 to have a rising vertical hose portion 31 which is disposed in an upward direction from the drain pump 20.

In addition, it is arranged so that the rising horizontal hose portion 32 continues in the horizontal direction from the rising vertical hose portion 31 and the external air at the time of stopping the operation of the drain pump 20 in the middle of the rising horizontal hose portion 32. Siphon preventing means 40 to be introduced into the rising horizontal hose unit 32 is installed.

And it is to be piped so that the descending vertical hose portion 33 is lowered from the rising horizontal hose portion (32).

The rising vertical hose portion 31, the rising horizontal hose portion 32 and the falling vertical hose portion 33 can be piped by one discharge hose 30, in some cases connected in a state separated from each other The pipe may be connected by a pipe (not shown).

In addition, although the discharge hose 30 mainly uses a vinyl hose, it may be made to pipe by a pipe depending on a case.

2 to 4, the siphon prevention means 40 includes a fluid conduit portion 41 having a fluid passage hole 43 having a fluid inlet 43a and a fluid outlet 43b.

In addition, in the middle of the fluid pipe portion 41 formed in a straight line shape to the air pipe portion 44 protruding in a direction perpendicular to the air pipe portion 44 to have an air passage hole 45 in communication with the fluid passage hole 43. Consists of.

The fluid pipe part 41 has hose connecting portions 42 and 42 'which are respectively connected to the middle portion of the rising horizontal hose portion 32 on both sides thereof, so that the siphon preventing means 40 is provided at the middle portion of the rising horizontal hose portion 32. It is configured to be connected.

In addition, the air passage hole 45 is configured to have an air opening and closing portion 46 to open and close the air inlet hole 47.

The air opening and closing portion 46 is configured to have a support jaw portion 461 and the air passage groove portion 462 provided in a plurality at equal intervals in the circumferential direction on the air passage hole 45.

And the air inlet pipe 465 having a close contact with the air inlet hole (47) (464) in the direction opposite to the air through the groove 462, the air through the groove 463 and the close contact ( 464)) is provided to have a packing moving hole (466).

The air inlet pipe 465 may be coupled to the air pipe 44 in some cases and may be coupled to be fastened by a screw thread (not shown) in some cases.

Therefore, the packing member 467 in the packing moving hole 466 by first inserting the packing member 467 into the packing moving hole 466 before the air inlet pipe 465 is coupled to the air inlet pipe 465 is coupled. ) Is built to be movable.

The packing member 467 is preferably a rubber having good sealing properties and fluidity, but in some cases, synthetic resin or other material having a specific gravity lower than water may be used.

Therefore, the present invention is installed so that the siphon prevention means 40 is connected to the middle of the rising horizontal hose 32 while the discharge hose 30 is piped as shown in FIG.

The end discharging portion 30a of the discharge hose 30 is piped to be positioned below the air conditioner 11 position, and the end discharging portion 30a of the discharge hose 30 is disposed below the air conditioner 11 position. The piping to be positioned is not arbitrarily piped as such, but most of the end discharge portion 30a of the discharge hose 30 is located below the position where the air conditioner 20 is installed in the conditions where the air conditioner 10 is installed. This is because most of the time. In particular, in the case of the wall-mounted air conditioner, the end discharging portion 30a of the discharge hose 30 is often piped at a position lower than the position of the air conditioner 10 than the installation position of the air conditioner 10.

Therefore, in the present invention, when the pump is operated by the drainage pump 20, the condensed water w is transported and discharged along the discharge hose 30.

Therefore, as shown in FIG. 5, the condensate (w) flows along the fluid passage hole 43 of the siphon prevention means 40, and is discharged. At this time, the air opening and closing portion 46 at the instantaneous pressure of the fluid flows through the condensate (w). By pushing up the packing member 467 of the c), the packing member 467 is moved upward from the packing moving hole 466 to be in close contact with the close contact portion 464.

And while the condensate (w) flows into the fluid passage hole 43, the packing member 467 is kept in close contact with the contact jaw portion 464, the condensate (w) flows out to the air inlet hole 47 Will not be.

Therefore, the condensate (w) is not leaked from the siphon prevention means 40 while the drain pump 20 is in operation, thereby enabling a good drainage action.

And when the pumping operation is stopped by the operation of the drain pump 20 is stopped all the flow of fluid (condensed water) in the discharge hose 30, but the siphon phenomenon that further sucks the condensate (w) occurs.

Therefore, in the fluid passage hole 43 of the siphon prevention means 40, the condensate water w flows in the direction of the fluid outlet 43b as shown by the arrow in FIG. 3, and condensate water w in the air passage hole 45 is thereby caused. By flowing toward the fluid outlet 43b, the packing member 467, which is in close contact with the contact jaw portion 464, is moved downward from the packing moving hole 466.

Therefore, as shown in FIG. 6, the packing member 467 moved downward while being in the state where the air inlet hole 47 is opened is placed on the plurality of supporting jaws 461.

Therefore, the external air flowing into the air inlet hole 47 passes through the plurality of air passage grooves 462 between the plurality of support jaw portions 461 as shown in FIG. 4 and the fluid passage hole through the air passage hole 45. It is in a state flowing into (43).

Therefore, even if the operation of the drain pump 20 is stopped and siphon occurs, external air flows into the fluid passage hole 43 so that the rising horizontal hose part 32a and the descending vertical hose part connected to the fluid outlet 43b in FIG. The condensate w in the 33 is discharged to the discharging end 30a, but the condensate w in the ascending vertical groove 31 remains as it is.

That is, the siphon action force for sucking the condensate w due to the siphon phenomenon cannot be blocked toward the fluid inlet 43a of the fluid pipe part 41 due to the inflow of external air from the siphon prevention means 40, so that the vertical rise is vertical. The condensed water w in the groove 31 remains as it is without being sucked into the discharging end 30a of the discharge hose 30.

In order to facilitate the understanding of the present invention, since all the pumping outlets (not shown) inside the drain pump 20 used for the air conditioner have a non-return valve 22, the condensed water w in the ascending vertical groove 31 is intact. The condensate (w) in the sump (21) of the drainage pump 20 is also left without being sucked out.

Therefore, even when the operation of the drain pump 20 is stopped, the condensed water w in the rising vertical hose part 31 and the drain pump 20 remains as it is, without being sucked into the siphon phenomenon. It doesn't happen at all.

In addition, since all the condensate (w) in the drain pump 20 remains without exiting, it can serve as a cooling water to cool the pump and increases the lubricity inside the pump, thereby shortening the life of the drain pump 20. It can be prevented in advance.

And the drain pump 20 is provided with a sump (21), as shown in Figure 1 to be pumped, but there is also no sump.

Therefore, the absence of the sump will generally use an injection pump (or solenoid pump, also referred to as an electronic pump), and the present invention uses the injection pump 20 'in the rising vertical hose portion 31 as illustrated in FIG. Even when used in connection, the same function as already described above.

In addition, since the injection pump 20 'also has a backflow prevention function, the condensate w remaining in the vertical hose 31 by the operation stops does not go back into the injection pump 20'. In addition, the condensate (w) remaining in the injection pump 20 'will remain as it is without being sucked out by the siphon phenomenon.

Although the present invention has been described by one embodiment, it is not limited thereto, and may be modified and implemented by those skilled in the art to which the present invention belongs, and it should be widely applied and protected without departing from the scope of the claims. It is self-evident.
