Description

Condensate discharge device for air conditioner}

The present invention relates to a condensate discharge device for an air conditioner that can efficiently remove foreign substances contained in condensate generated inside an air conditioner.

In general, condensation water generated during operation of an air conditioning system contains various foreign substances generated from air flowing in from the outside and various other factors.

Such foreign substances move along the drain line and form sediment.

However, if a large number of sediments are generated, the drain line may become clogged and the drain function may be paralyzed, which may have a negative impact on air conditioning systems, pharmaceuticals, and semiconductor processes.

Therefore, taking this into account, a method is required to prevent drain line clogging by easily removing sediment.

In addition, for example, in the case of an air conditioning system applied to a pharmaceutical factory, air conditioners for various purposes such as air conditioners for blowing air in offices or hallways and air conditioners for blowing clean products are installed separately. Due to the nature of each air conditioner, the particle size of the emitted foreign substances is different. In other words, a structure for filtering foreign substances of various particle sizes is required, and currently, filtering devices with different structures are being applied.

The present applicant additionally proposes a method for common use of various filtering devices that are separately applied depending on the characteristics of the air conditioner.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below and will be implemented in various different forms. These embodiments only serve to ensure that the disclosure of the present invention is complete and to fully convey the scope of the invention to those skilled in the art. This is provided to inform you. In the drawings, like symbols refer to like elements.

The condensate discharge device for an air conditioner according to a preferred embodiment of the present invention not only improves pipe clogging caused by foreign matter deposits by installing a partition using a mesh network, but also improves the foreign matter particles generated inside the air conditioner depending on the air conditioner. It has a structure that can respond flexibly even when size changes, so it can be integrated and applied to various air conditioners.

Hereinafter, the present invention will be described in detail with reference to examples.

As shown in FIG. 1, the condensate discharge device 100 for an air conditioner according to an embodiment of the present invention is for discharging condensate generated inside the air conditioner 10 that supplies purified air to the outside, and is connected to the first drain pipe 110. ), a second drain pipe 120, and a trap 130.

The first drain pipe 110 is connected to the inside of the air conditioner to discharge condensate collected inside the air conditioner 10, and is provided with a valve to allow or block the flow of condensate. Generally, inside the air conditioner 10, a filter to filter out foreign substances in the incoming air, a heat exchanger to control the temperature of the air to be supplied, etc. are installed. Among the heat exchangers, in the evaporator, condensate is deposited on the surface due to the temperature difference with the surrounding air. This condensate is collected in a separate collection tray and then guided to the first drain pipe 110.

In this way, the condensed water guided to the first drain pipe 110 may contain foreign substances such as dust flowing into the air conditioner from the outside of the air conditioner, metal powder generated by corrosion of heat exchanger parts, etc. Differences in the generation of foreign substances by air conditioner will be explained in more detail below.

The second drain pipe 120 is installed spaced apart from the first drain pipe 110, and similarly, a valve is provided to control the flow of condensate, and the condensate passing through the first drain pipe 110 flows into the post-process line, etc. is discharged as

As shown in FIGS. 1 to 3, the trap 130 connects the first drain pipe 110 and the second drain pipe 120, and ensures that the condensate flowing in through the first drain pipe 110 is constant. It has an internal space so that the water level can be stored at all times. Accordingly, it is possible to prevent odors, polluted gases, etc. formed on the second drain pipe 120 from flowing back through the trap 130 into the first drain pipe 110 and the inside of the air conditioner.

Inside the trap 130, a partition 140 is provided to partition the internal space, and a filter unit 160 is provided on the upper side of the partition 140 to filter out foreign substances such as dust and metal powder floating in the condensate.

The trap 130 includes a trap body 170 having a container structure with a partition wall 140 and a filter unit 160 provided on the inside and an open upper side, and a door that opens or closes the upper opening of the trap body 170 ( 180).

The lower end of the first drain pipe 110 is formed at a lower position than the second drain pipe 120. Accordingly, a certain amount of condensate is always stored inside the trap body 170, and this trap is a type of drum. It may have a trap form.

Meanwhile, foreign matter that flows into the trap body 170 through the first drain pipe 110 like condensate is filtered by the partition wall 140 and the filter unit 160, and the condensate water located on one side with respect to the partition wall 140 is filtered out. Floating within or stacked on the bottom. When used for a long time, the amount of accumulated foreign substances increases, and the worker can periodically open the door 180 to remove the accumulated foreign substances.

In an embodiment of the present invention, as shown in FIGS. 2 and 3, the filter unit 160 is installed to be detachable from the trap 130 and is seated on the upper part of the partition wall 140 in an overlapping state. It includes at least two mesh networks 162 that can be easily installed.

The operator can use two, three, or four mesh networks 162 overlapping as appropriate depending on the type of air conditioner, that is, according to the increase or decrease in the size of foreign particles contained in the discharged condensate. In other words, there is no need to separately prepare a plurality of traps 130 equipped with mesh nets with different mesh sizes according to changes in the size of foreign matter particles and install them in each location, and one trap 130 is installed in common. If necessary, the number of overlapping mesh nets 162 inside the trap body 170 can be adjusted and used.

To elaborate, as shown in FIG. 4(a), in the case of the first air conditioner that receives outdoor air, removes foreign substances, controls temperature/humidity, and then supplies outdoor air to offices, hallways, etc. in the building, mainly from outside air. Since condensed water often contains foreign substances with small particle sizes, such as incoming dust, a filter unit 160 capable of filtering out small particle size foreign substances is required.

In contrast, as shown in FIG. 4(b), pre-processed air is supplied, foreign matter is removed, temperature/humidity is controlled, and then supplied to the clean room for pharmaceuticals in the building or semiconductor manufacturing process. In the case of a second air conditioner receiving dirty air, as the acidic cleaning solution vapor generated in the clean room flows into the second air conditioner, corrosion of the internal parts of the second air conditioner occurs frequently, and metal powder, a result of corrosion, is included in the condensate. In many cases, a filter unit 160 that can filter out foreign substances of larger particle size is required. Relatively, the condensate discharged from the second air conditioner contains almost no small particle size foreign substances such as dust.

In other words, the size of foreign matter particles contained in the condensate discharged from the air conditioner may vary depending on the function of the air conditioner, the supply location of the air supplied, etc., and the present invention is applicable to air conditioners installed in various places through a single trap 130 structure. We propose a structure that allows for common installation and can flexibly filter foreign substances of various particle sizes.

Specifically, as shown in FIGS. 2 and 3, multi-stage stepped steps 141 are provided on the upper part of the partition wall 140, and the filter unit 160 is located on the upper surface of each of the multi-stage stepped steps 141. It includes at least two mesh nets 162 each seated on the upper surfaces of at least two steps 141 in a state where they can overlap each other.

Here, at least two mesh networks 162 are formed to have the same mesh size. That is, at least two mesh networks 162 are applied identically, each made of the same mesh size, mesh shape, and material.

Hereinafter, for convenience of explanation and illustration, the description will be based on the case where three steps 141 are provided as shown in FIGS. 1 to 3.

In cases where filtering of smaller particle size foreign substances is required, such as in the first air conditioner, for example, the operator mounts all the mesh nets on the upper surface of the three steps 141, so that the three mesh nets 162 overlap each other. It can be used as, and in this case, due to the three mesh network overlapping structure, the filter unit 160 can stably filter even small particle size foreign substances.

On the other hand, in cases where filtering of large particle size foreign substances is required rather than small particle size filtering, such as in the second air conditioner, for example, the worker installs a mesh net on the upper surface of the two steps 141 to form two mesh nets ( 162) can be used in an overlapping state, and in this case, due to the structure of two mesh networks overlapping, the filter unit 160 can focus on filtering foreign substances with relatively large particle sizes compared to the state in which three mesh networks are overlapped. .

In this case, as described above, filtering of large particle size foreign substances is possible through the three mesh network overlapping structure, but there is a problem of resistance to condensate flow compared to the two mesh network overlapping structure. Therefore, a two-mesh network overlapping structure can be applied to enable rapid flow without generating resistance to the condensate flow and also to stably filter foreign substances of the required particle size.

In the present invention, a multi-stage stepped step 141 is formed on the upper part of the partition wall 140, and a mesh network 162 of the same shape is formed in two, three, or three layers depending on the condensate of the air conditioner (particle size of contained foreign substances, etc.). More overlaps can be used as needed, and foreign substances of various particle sizes can be filtered through one and the same trap (130).

As shown in FIG. 2, an insertion groove 143 is provided on the upper surface of the multi-stage step 141 so that the lower ends of at least two mesh nets 162 are respectively inserted. Here, the depths of all insertion grooves 143 are formed to be the same.

In addition, a guide groove 171 is provided on the inner wall of the trap 130 to guide the downward insertion of the at least two mesh nets 162 into the insertion groove 143. Guide grooves 171 are formed on both opposing inner walls of the trap body 170 so that both sides of the mesh network 162 are partially inserted.

Therefore, when installing/replacing the mesh net, the worker opens the door of the trap body 170, inserts both ends of the mesh net 162 into the guide groove 171, and then lowers the lower end into the insertion groove 143. It can be inserted and fixed inside.

As the lower end of the mesh net 162 is inserted and fixed in the insertion groove 143, at least two mesh nets 162 are kept within the trap body 170 even if condensate is discharged rapidly and in large quantities. It can be maintained in a stable installed state.

In an embodiment of the present invention, as shown in FIG. 5, the mesh of the mesh network 162 is formed in a square shape and the height of each of the multi-stage stepped steps 141 is the same.

In addition, when the number of stepped steps 141 is n and the height of the mesh size is h, the height of the stepped steps 141 is applied as h/n.

Additionally, if the number of step steps 141 is three and the height of the mesh net 162 is 3 mm, the height of each of the three step steps 141 is set to 1 mm. Therefore, in a state where the three mesh nets 162 are installed to overlap each other, the height of the net that actually filters foreign substances in the entire filter unit 160 consisting of the three mesh nets 162 can be set to 1 mm instead of 3 mm. , By using three mesh networks of the same shape and structure overlapping, it is possible to filter out contaminants of smaller particle size.

In other words, the present invention does not require separate preparation and installation of mesh nets with different mesh sizes according to the change in particle size of the foreign matter to be filtered, but instead uses a plurality of mesh nets (162) with the same mesh size in an appropriate number as needed. It can be used overlappingly, and as described above, even if the size of the condensate particles discharged from air conditioners for various purposes (blowing to indoor offices/corridors, blowing to clean rooms) is different, one trap (130) can be used. Can be filtered efficiently.

Although the present invention has been shown and described in connection with preferred embodiments for illustrating the principles of the invention, the invention is not limited to the construction and operation as shown and described. Rather, those skilled in the art will understand that numerous changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
