The present invention relates to an air conditioner, and more particularly, to an air conditioner having a drain hose formed by overlapping a heat insulating member and being formed to have flexibility.

In general, an air conditioner is a cooling / heating system that cools a room by a repetitive action of inhaling hot air in a room, exchanging heat with a low temperature refrigerant, and then discharging it into the room. -Condenser-Expansion valve-Evaporator which forms a series of cycles.

In particular, the air conditioner is mainly an outdoor unit (sometimes called 'outside' or 'heat sink') installed outdoors, and an indoor unit (sometimes called 'indoor' or 'heat absorbing side') mainly installed inside a building. The outdoor unit is provided with a condenser (outdoor heat exchanger) and a compressor, and the indoor unit is provided with an evaporator (indoor heat exchanger).

In the indoor unit, condensate is generated during heat exchange between the refrigerant and the air, and the condensate is forced by a drain pump forcing the condensate flow and drained to the outside through the drain hose.

Hereinafter, the installation structure of the drain hose will be described by taking the ceiling type air conditioner as an example.

The drain hose is installed to communicate with the inside of the drain pump (not shown) to guide the drainage direction of the condensate flowing by the drain pump.

The drain hose 10 has a plurality of PVC pipes 12 cut to a suitable size and a joint 14 for connecting the plurality of PVC pipes, and insulation for insulating the joint 14 and the PVC pipe 12. It comprises a member (not shown).

In addition, the drain hose 10 is installed so that the center portion is bent upward as shown in FIG. 1 by cross-connecting the fitting hole 14 and the PVC pipe 12.

Therefore, the condensed water flowing along the drain hose 10 does not flow back into the indoor unit 1 again.

The heat insulating member is covered on the outside of the fitting hole 14 and the PVC pipe 12. The heat insulating member is to prevent the cold condensed water passing through the fitting hole 14 and the inside of the PVC pipe 12 to heat exchange with the outside, to prevent dew condensation.

Therefore, due to a lot of work maneuver enormous time is required and there is a problem that the installability is degraded.

In addition, when a gap is generated inadvertently by the operator when connecting the PVC pipe 12 and the fitting port 14, there is a problem that the condensate leaks.

In addition, leakage of cold condensate is not preferable because it causes dew formation on the outer surface of the drain hose 10.

Hereinafter, the configuration of the air conditioner according to the present invention will be described with reference to FIG.

Figure 2 is an installation state diagram schematically showing the appearance of the air conditioner according to the present invention is installed.

In general, the air conditioner is composed of an indoor unit 100 for exchanging and discharging indoor air, and an outdoor unit for exchanging air heat-exchanged with air while passing through the indoor unit 100, but the drain is a main component of the present invention. Only the indoor unit 100 directly associated with the hose 200 will be described.

The indoor unit 100 of the air conditioner is fixed to the upper part is inserted into the ceiling (W), the lower surface is exposed to the lower side of the ceiling (W).

And, the indoor unit 100 is coupled to a plurality of panels to form the front / rear and left / right surface appearance, the suction grill for guiding the indoor air flows into the indoor unit 100 on the lower surface of the indoor unit ( 120).

More specifically, a plurality of suction holes (not shown) drilled into the indoor unit 100 are drilled in the central portion of the suction grill 120, and a discharge hole (not shown) is formed outside the suction hole, that is, the edge of the suction grill 120. Is provided.

Therefore, the indoor air introduced into the indoor unit 100 through the suction grill 120 undergoes heat exchange in the indoor unit 100 and is then discharged back into the room through the discharge port.

Although not shown, a heat exchanger is formed in the indoor unit 100 so that the refrigerant flows, and the heat exchanger exchanges the indoor air introduced into the indoor unit 100 through the suction port with the refrigerant.

In general, a drain pan (not shown) is provided at a lower side of the heat exchanger to collect condensed water generated when the refrigerant and indoor air are heat exchanged, and at one side of the drain pan to drain the collected condensed water to the outside of the indoor unit 100. Drain pump (not shown) is provided.

On the other hand, the upper portion of the right side of the indoor unit 100 is provided with a drain hose 200 which is a main component of the present invention. The drain hose 200 has a left end communicating with the inside of the drain pump and a right end exposed to the outside to guide the condensed water forced by the drain pump to the outside.

'형상을 가진다.That is, a fitting hole 220 is provided at the left end of the drain pump, and the fitting hole 220 is coupled to communicate with the inside of the drain pump. And, the fitting port 220 is approximately 'when viewed from the front

'Have a shape.

Therefore, the condensed water introduced into the fitting hole 220 is guided upward, and even if the drain hose 200 is installed to be inclined upward to the right to prevent the backflow of the condensate, the occurrence of stress is minimized in the fitting hole 220. This can prevent damage.

Hereinafter, an internal configuration of the drain hose 200 will be described with reference to FIGS. 3 to 4B.

3 is a partial cutaway view showing an internal configuration of a drain hose which is a main component of an air conditioner according to the present invention, and FIG. 4A illustrates an internal configuration of an embodiment of a drain hose which is a main configuration of an air conditioner according to the present invention. Figure 4b is shown a longitudinal cross-sectional view, Figure 4b is a longitudinal cross-sectional view showing the internal configuration of another embodiment of the drain hose which is the main configuration of the air conditioner according to the present invention.

As shown in these figures, the drain hose 200, the inner tube 240 for guiding the flow direction of the condensate, and the heat insulating member wound around the outer peripheral surface of the inner tube 240 to block heat exchange between the condensate and the outside air ( 260 and a film 280 provided outside the heat insulating member 260 to block contact between the heat insulating member 260 and foreign matter.

The inner tube 240 is bored in the longitudinal direction to form a flow path of condensed water, it is formed of a flexible material. The spiral protrusion 242 is formed on the outer circumferential surface of the inner tube 240 in a spiral shape.

The spiral protrusion 242 is configured to prevent damage to the inner tube 240 due to bending stress applied to the drain hose 200 when the drain hose 200 is installed. That is, the spiral protrusion 242 is formed integrally with the inner tube 240 so as to have an elastic force on the outer circumferential surface of the inner tube 240 and prevents the bending stress applied to the inner tube 240 from being concentrated locally. It serves to prevent folding and breakage of the 240 in advance.

The heat insulating member 260 is provided on the outer side of the inner tube 240. The heat insulating member 260 is formed of a material having heat insulating properties to block heat exchange between the inner tube 240 and the outside air.

In more detail, the heat insulating member 260 blocks dew from the outer circumferential surface of the inner tube 240 by blocking cold air transferred from the cold condensate passing through the inner tube 240 to the inner tube 240 from contacting the outside air. Serves to prevent.

Therefore, the heat insulating member 260 is preferably wound tightly so as not to be missed when wound on the outer peripheral surface of the inner tube (240).

Hereinafter, a detailed configuration of the heat insulating member 260 will be described with reference to FIGS. 4A and 4B. When the heat insulating member 260 is wound on an outer circumferential surface of the inner tube 240, a part of the heat insulating member 260 is wound to overlap.

That is, the left upper surface of the heat insulating member 260 previously wound is wound so as to overlap the right bottom surface of the heat insulating member 260 which is subsequently wound in surface contact, and as shown in FIG. 4A, the width of the heat insulating member 260 is 1. / 2 or more overlap.

In addition, the heat insulating member 260 is joined between the pair of spiral protrusions 242 adjacent to each other to be in surface contact. That is, when the heat insulating member 260 is wound around the outer circumferential surface of the inner tube 240, a portion of the outer surface of the heat insulating member 260 which contacts the outer circumferential surface of the inner tube 240 is connected to a pair of spiral protrusions 242 adjacent to each other. (See reference numeral “A” in FIGS. 4A and 4).

In addition, a portion included in the region “A” of the heat insulating member 260 corresponds to a shape formed by the pair of adjacent spiral protrusions 242 and the outer circumferential surface of the inner tube 240. Therefore, when the heat insulating member 260 is wound between the pair of spiral protrusions 242, the lower left side of the heat insulating member 260 is located on the right outer surface and the right side of the spiral protrusion 242 located on the left side. The outer surface of the

To this end, the heat insulating member 260 is in contact with the outer circumferential surface of the inner tube 240 to block the contact between the inner tube 240 and the air, and is formed extending from the right end of the heat insulating layer 262 to the right and adjacent It is composed of a reinforcing layer 264 is superposed on the outer side of the heat insulating layer 262.

The heat insulation layer 262 is a portion corresponding to the area "A" in FIG. 4A, and the reinforcement layer 264 is a portion extending from the right end of the heat insulation layer 262 to the right side. In addition, the heat insulation layer 262 and the reinforcement layer 264 are integrally formed.

The heat insulation layer 262 and the reinforcement layer 264 may be variously implemented in shape. That is, when the reinforcement layer 262 is wound on the outer surface of the heat insulation layer 262, the shape of the reinforcement layer 262 and the heat insulation layer 262 may be varied in a shape range such that the outer side of the spiral protrusion 242 is formed thickest. It is possible to implement.

The reason for the above configuration is that when the drain hose 200 is bent, the reinforcement layer 262 and the heat insulation layer 262 of the bent portion generate tensile and compressive stresses. 260) in order to block a decrease in thermal insulation as the thickness decreases.

On the other hand, the left / right end of the heat insulating layer 262 is provided with a quarter-shaped (fan-shaped) projection insulation portion 266. The protrusion insulation unit 266 is configured to shield a part of the outer surface of the spiral protrusion 242 so that the spiral protrusion 242 may be insulated from the outside air.

That is, as mentioned above, when the heat insulating member 260 is wound on the outer circumferential surface of the inner tube 240, the left side of the heat insulating member 260, that is, the heat insulating layer 262 is wound between the pair of spiral protrusions 242. The protrusion insulation part 266 surrounds half of the outer circumferential surface of the spiral protrusion 242.

Therefore, the protrusion insulation portion 266 is preferably formed to have a curvature corresponding to the curvature of the outer circumferential surface of the spiral protrusion 242, when the heat insulating member 260 is wound around the outer circumferential surface of the inner tube 240 The outer surface of one spiral protrusion 242 may be completely insulated by the protrusion insulation unit 266.

To this end, the width of the heat insulating layer 262 is preferably formed to be wider than the distance between the adjacent pair of spiral projections 242.

The heat insulating layer 262 and the reinforcing layer 264 are formed to have different thicknesses. That is, the reinforcement layer 264 is formed thicker than the heat insulation layer 262.

This is because the region where the spiral protrusion 242 is formed is relatively thicker than the portion where the spiral protrusion 242 is not formed, and thus it is not easy to transfer cold air from the condensed water passing through the inner tube 240.

Therefore, since the cool air delivered from the condensate is concentrated to a portion having a relatively thin thickness, for this reason, when the same thicknesses of the reinforcing layer 264 and the heat insulating layer 262 are formed, the heat insulating performance is deteriorated.

The upper right surface of the heat insulation layer 262 and the right lower surface of the reinforcement layer 264 have shapes corresponding to each other. That is, as shown in FIG. 4A, the upper right side surface of the heat insulation layer 262 is recessed in the lower right direction, and the lower right side surface of the reinforcing layer 264 protrudes in the lower right direction.

Therefore, even when the heat insulating member 260 is wound several times and the reinforcing layer 264 overlaps the top of the heat insulating layer 262, the appearance of the upper end of the reinforcing layer 264 is not large. In addition, even when bending stress is generated for the installation of the drain hose 200, the heat insulating layer 262 and the reinforcing layer 264 are kept in surface contact with each other without being separated from each other.

In addition, the heat insulating layer 262 and the reinforcing layer 264 may be shaped as shown in FIG. 4B. That is, the right upper surface of the heat insulation layer 262 may protrude to be rounded upward, and the right lower surface of the reinforcement layer 264 may be recessed to be rounded upward to have a shape corresponding to each other. will be.

Hereinafter, a process of manufacturing the drain hose 200 configured as described above will be described with reference to FIGS. 4A and 4B.

First, when the inner tube 240, the heat insulating member 260, and the coating 280 are prepared in a single unit state, the heat insulating member 260 is wound around the outer circumferential surface of the inner tube 240.

In this case, the heat insulation layer 262 is inserted between the adjacent pair of spiral protrusions 242 to match the appearance of the inner tube 240, the reinforcement layer 264 is spaced apart from the outer peripheral surface of the inner tube (240). In addition, the protrusion insulation portion 266 provided at the vertebral side end of the heat insulation layer 262 surrounds half of the exterior area of the spiral protrusion 242.

Then, when the insulation member 260 is further wound one more time, the insulation layer 262 is positioned on the left side of the spiral protrusion 242 previously wound, and the protrusion located on the right side of the pair of protrusion insulation units 266. The heat insulation part 266 surrounds an outer surface 1/2 of the spiral protrusion 242 that remains in an unwrapped state.

At the same time, the bottom surface of the reinforcing layer 264 is seated on the top surface of the heat insulating layer 262, and if the above process is repeated, the heat insulating member 260 is shown on the outer peripheral surface of the inner tube 240, 4a and 4b. It can be wound in the same state as.

When the heat insulating member 260 is completely wound on the outer circumferential surface of the inner tube 240, when the outer surface of the heat insulating member 260 is wrapped using the coating 280, the heat insulating member 260 and the inner tube 240 are coated. Positioned inside the 280 may be blocked contact with the foreign object.

Since the fitting hole 220 is attached to one end of the heat insulating member 260, the production of the drain hose 200 is completed.

And, even if the drain hose 200 made by the above process is installed in a state bent in the upper side of the ceiling (W) as shown in Figure 2, the heat insulating layer 262 and the reinforcing layer 264 is kept in an overlapping state with each other Dew condensation on the outer surface of the drain hose 200 due to leakage can be blocked.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications may be made based on the present invention to those skilled in the art within the above technical scope.

For example, in the embodiment of the present invention, the right upper surface of the heat insulating layer 262 and the right lower surface of the reinforcing layer 264 are configured to be formed to have a curvature corresponding to each other, but the heat insulating layer 262 and the reinforcing layer 264 are configured. ) May be configured to be combined into various shapes within the range that can be overlapped.

In the air conditioner according to the present invention having the configuration as described above, it is configured to overlap each other when the heat insulating member is wound on the outer peripheral surface of the inner tube constituting the drain hose.

Therefore, even when bending stress is applied to the drain hose, since the heat insulation layer and the reinforcement layer are kept in an overlapped state, there is an advantage that cold air leakage is blocked.

In addition, due to the maximization of the thermal insulation efficiency there is an advantage that the dew condensation defect is prevented in advance.

And in this invention, when a heat insulation member is wound around an inner tube outer peripheral surface, a heat insulation layer is comprised between a pair of adjacent spiral protrusions.

Therefore, the outer peripheral surface of the inner tube is in contact with the heat insulating member as a whole has the advantage that the heat insulating performance is improved.

In addition, there is an advantage that the installability is improved due to the number of parts when installing the drain hose.
