- the desired height is one third of a height of the evaporator E. This is caused by that, even if the condensate is dropped to left and right side surfaces of the evaporator E, it is not apprehended due to a high dropping speed of the condensate that the condensate is leaked through a gap formed at the left and right side walls of the air conditioning case 1000 .
- the second and third grooves 120 a and 130 a corresponding to the second and third protrusions 120 b and 130 b may be formed to be extended to an end side of the first and second condensate discharging passages 400 and 500 .

- a dash panel (not shown) for partitioning an internal portion of the vehicle and an engine room is interposed.
- the first and second condensate discharging passages 400 and 500 pass through the dash panel (not shown). Therefore, when the condensate discharging passages 400 and 500 may be vibrated together with the dash panel contacted with the outer surfaces of the condensate discharging passages 400 and 500 due to vibration of the vehicle, the vibration may be amplified, or the condensate discharging passages 400 and 500 may be damaged. In order to buffer the vibration, as shown in FIG.
- a joint portion 720 of a grommet 800 which is formed with a groove 710 , is provided.
- the grommet 800 is inserted onto the outer surfaces of the condensate discharging passages 400 and 500 in order to buffer between the condensate discharging passages 400 and 500 and the dash panel (not shown).
- the present invention since a coupling structure of the left and right cases is improved, it is possible to prevent a leakage of the condensate that is occurred at the evaporator and also to drain the condensate to an outside without a separate lower case, thereby reducing the number of components and work effort for the lower case.

Abstract
Description
- The present invention claims priority of Korean Patent Application No. 10-2009-0016491, filed on Feb. 26, 2009, which is incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to an air conditioner for a vehicle, and more particularly, to an air conditioner for a vehicle, which has an improved condensate discharging structure so as to prevent condensate from being leaked through a divided surface of a left and right divided type air conditioning case.
- 2. Description of Related Art
- In a heating ventilating and air conditioning (HVAC) system for controlling internal air of a vehicle, refrigerant is compressed by using a vehicle power system and condensed by external air and then rapidly expanded and evaporated, and the internal air may be ventilated to an evaporator and cooled by heat exchange at the evaporator when the refrigerant is evaporated, thereby obtaining cooled air, and also the internal air may be ventilated to a heater core and heated by heat exchange at the heater core using cooling water heated by an vehicle engine, thereby obtaining warm air.
- Generally, a (three-piece type) air conditioning case for a vehicle includes a left case, a right case and a lower case.
- According to an air ventilation process in the air conditioning case, external air is introduced into the air-conditioning case using a blower (not shown) and then passed through an evaporator. Since the evaporator is maintained at a lower temperature than an ambient temperature in a cooling mode, condensate is generated on a surface of the evaporator due to a low saturated vapor pressure.

FIG. 1 is a perspective view showing a conventional semi center type air conditioner 1. The air conditioner 1 includes anair conditioning case 20 in which anair inlet port 23 is formed at an air entering side thereof and a plurality ofair outlet ports 24 are formed at an air discharging side thereof, and aventilator unit 10 which selectively introduces internal or external air through an internal and externalair inlet port 11 formed at an upper side thereof and then forcibly ventilates the introduced air into theair inlet port 23. - As shown in
FIG. 2 , an evaporator E and a heater core (not shown) are disposed in turn in theair conditioning case 20, and also a temperature controlling door (not shown) for controlling temperature and a mode door (not shown) for performing various air conditioning modes are provided at theair conditioning case 20. - In the air conditioner 1, the air ventilated into the
air conditioning case 20 by theventilator unit 10 is passed through the evaporator E and then cooled or heated during an air conditioning process that selectively passes through the heater core by the temperature controlling door. The cooled or heated air is supplied into the vehicle through each duct connected with the plurality ofair outlet ports 24, thereby obtaining a desired air conditioning effect. - Meanwhile, when the air conditioning system is operated, since cooled refrigerant is circulated in the evaporator E, condensate is generated around the evaporator E during a heat exchange process with the external air.
- The condensate is flowed down along the evaporator E or dropped to a lower side of the
air conditioning case 20 by the ventilated air, and then discharged to an outside through acondensate discharging port 21 formed at a lower side of theair conditioning case 20. - Typically, the
air conditioning case 20 is comprised of anupper case lower case 20 c for preventing a leakage of the condensate. As shown inFIGS. 1 and 2 , the evaporator E is arranged between theupper case lower case 20 c. Theupper case left case 20 a and aright case 20 b. - The conventional
air conditioning case 20 has following problems. - Since the

Referring to the drawing, acondensate discharging passage FIG. 4 is a partial perspective view showing a lower side of the air conditioning case of the present invention, wherein acondensate discharging portion 600 is formed at abottom surface 100 a of thefirst case 1000 a. Although thecondensate discharging portion 600 is formed at thebottom surface 100 a of thefirst case 1000 a, this is a just example, and thecondensate discharging portion 600 may be formed at abottom surface 100 b of thesecond case 1000 b or formed at bothbottom surfaces second cases second cases - The first and
second cases second cases first case 1000 a and the protrusion is formed at thesecond case 1000 b, the present invention is not limited to the embodiment. In other words, the groove may be formed at thesecond case 1000 b and the protrusion may be formed at thefirst case 1000 a, and other various coupling structures may be also applied. - Referring to
FIGS. 5 and 7 , amain drain passage 200 is formed at a lower side of thefirst case 1000 a so that the condensate generated at the evaporator E and the like is introduced into thecondensate outlet port 600. That is, at the lower side of thefirst case 1000 a, there is formed themain drain passage 200 including afirst side wall 210 which is protruded to a lower side of the bottom surface of the first case, a firstbottom wall 220 which is connected with thefirst side wall 210 and afirst partition wall 230 which is spaced apart from thefirst side wall 210 and protruded to an upper side of the firstbottom wall 220. Thecondensate discharging port 600 may be formed by inwardly concaving a part of ajoint portion 110 a of thebottom surface 100 a of thefirst case 1000 a that is bonded with ajoint portion 110 b of thebottom surface 100 b of thesecond case 1000 b (referring toFIGS. 5 and 8 ). - As shown in
FIGS. 6 and 12 , thecondensate discharging port bottom surface 100 a of thefirst case 1000 a or thebottom surface 100 b of thesecond case 1000 b in order to smoothly discharge the condensate even when theair conditioning case 1000 is inclined during movement of the vehicle. The plurality ofcondensate discharging ports joint portions air conditioning case 1000 is also inclined behind and front or right and left. In order to prevent the condensate from being stayed in theair conditioning case 1000, particularly when the air conditioning case is inclined behind, the plurality ofcondensate discharging ports joint portion second case FIGS. 6 and 11 ). - With regard to the
main drain passage 200, the description thereof including thefirst side wall 210, firstbottom wall 220 and thefirst partition wall 230 is just provided for the sake of understanding the present invention. The drain passage may have various shapes, e.g., a rectangular or circular shape in section, which is formed to be protruded to a lower side of thebottom surface 100 a so that the condensate dropped from thecondensate discharging portion 600 is introduced to the firstcondensate discharging passage 400. - The condensate flowed along the
main drain passage 200 is discharged to an outside through the firstcondensate discharging passage 400. - As shown in
FIG. 9 , asub-drain passage 300 is formed at a lower side of thesecond case 1000 b to be corresponding to thefirst case 1000 a including thefirst partition wall 230 and the like, so that the condensate dropped from thecondensate discharging portion 600 is introduced to the secondcondensate discharging passage 500, or the condensate overflowed from themain drain passage 210 is received therein and then discharged to the secondcondensate discharging passage 500. In other words, at the lower side of thesecond case 1000 b, there is formed thesub-drain passage 300 including asecond side wall 310 which is protruded to the lower side of thebottom surface 100 b of thesecond case 1000 b, a secondbottom wall 320 which is connected with thesecond side wall 310 and asecond partition wall 330 which is spaced apart from thesecond side wall 310 and protruded to an upper side of the secondbottom wall 320. - The condensate flowed along the
sub-drain passage 300 is discharged to an outside through the secondcondensate discharging passage 500. - As described above, the
main drain passage 200 and thesub-drain passage 300 are respectively formed at the bottom surfaces 100 a and 100 b of the first andsecond cases second partition walls partition walls sub-drain passages 200 and 300 (referring toFIGS. 3 to 7 ). - In case that the first and
second case second cases joint portions main drain passage 200 or thesub-drain passage 300 and then flowed to the first or secondcondensate discharging passage - Meanwhile, the condensate may be leaked through a gap formed at a bonded surface 233 (reference to
FIG. 9 ) of the first andsecond partition walls FIGS. 7 to 9 , abent portion 231 may be formed at one of the first andsecond partition walls upper surface 331 of the other partition wall. - Alternatively, as shown in
FIG. 10A , anupper end second partition wall second partition wall main drain passage 200 or thesub-drain passage 300, thereby preventing introduction of the condensate to the bondedsurface 233. Otherwise, as shown inFIG. 10B , a height of thefirst partition wall 230 may be higher than that of thesecond partition wall 330 in order to prevent the introduction of the condensate to the bondedsurface 233. - Referring to
FIGS. 5 to 7 , in order to prevent the leakage of the condensate and facilely couple the first andsecond cases second partition wall first groove 221 is formed at a lower side of one of the first or secondbottom wall first protrusion 321 is also formed at a lower side of the other bottom wall. Although not shown, a sealing member (not shown) may be inserted into thefirst groove 221 for insertion of thefirst protrusion 321 so as to prevent the leakage of the condensate. - Hereinafter, a position of the
condensate discharging port 600 will be described with reference toFIG. 9 . A center portion of thecondensate discharging port 600 is spaced apart from the bondedsurface 233 in a desired distance D. Due to such structure, it is previously prevented that the condensate is directly dropped from thecondensate discharging port 600 to the bondedsurface 233. And due to such position of thecondensate discharging port 600, it is prevented that the condensate is introduced into the bondedsurface 233. Thebent portion 231 may be formed at one of the first andsecond partition walls upper surface 331 of the other partition wall. A length L of thebent portion 231 is formed to be larger than a sum l of thicknesses of the first andsecond partition wall surface 233. Further, a height of the first andsecond partition walls main drain passage 200 and thesub-drain passage 300, and thus when the condensate is excessively introduced into themain drain passage 200, some of the condensate is introduced into thesub-drain passage 300. Due to such shape and structure of the first andsecond partition walls main drain passage 200, the condensate is introduced into thesub-drain passage 300 formed at the lower side of thesecond case 1000 b and then discharged to an outside of the air conditioning case through the secondcondensate discharging passage 500. - A slope is formed so that the main and
sub-drain passages condensate discharging passage FIG. 11 , preferably, the slope has an angle of 20 to 25° so that the condensate is facilely flowed from the main andsub-drain passages condensate discharging passage sub-drain passages sub-drain passages air conditioning case 1000. In general, when a vehicle travels along a sloped road, an angle of inclination is not exceeded by 20°. Therefore, it is preferable that the slope has an angle of 20 to 25°. As described above, thecondensate discharging port bottom surface 100 a of thefirst case 1000 a or thebottom surface 100 b of thesecond case 1000 b in order to smoothly discharge the condensate even when theair conditioning case 1000 is inclined during the movement of the vehicle. - In relation to this, the inventor of the present invention has performed an experiment in a state that the
air conditioning case 1000 is inclined behind and front or left and right at an angle of 20°, and then confirmed a fact that the condensate was not leaked. The experiment was performed in a state that a vehicle air conditioner was operated at a high/low air volume when an external environment shows a high/low percentage of humidity, respectively. And in order to clearly confirm whether the condensate was leaked or not, a water-soluble paint having an opaque color was coated on the bonded surface of the first and second cases formed of a transparent material. Particularly, it was confirmed that the condensate was not leaked in a bad conditioned traveling state (e.g., the vehicle is inclined behind or front at an angle of 20°, or right or left at an angle of)20°. -
TABLE 1 A result table showing whether the condensate is leaked in each traveling state Traveling state of vehicle Result Left at an angle of 20° Not leaked Right at an angle of 20° Not leaked Front at an angle of 20° Not leaked Behind at an angle of 20° Not leaked Behind at an angle of 20° → Not leaked front at an angle of 20° Left at an angle of 20° → Not leaked right at an angle of 20° -
FIG. 12 shows a flowing direction of the condensate when the vehicle travels on a sloped road having an angle of 20°, andFIG. 13 shows a flowing direction of the condensate when the air conditioning case is rotated right while the vehicle travels on a curved road, andFIG. 14 shows a flowing direction of the condensate when the air conditioning case is rotated left while the vehicle travels on the curved road. - As shown in
FIG. 12 , since the plurality ofcondensate discharging ports joint portion second case FIG. 13 , most of the condensate is discharged through themain drain passage 200 when theair conditioning case 1000 is rotated right. As shown inFIG. 14 , the condensate is discharged through themain drain passage 200 and thesub-drain passage 300 when theair conditioning case 1000 is rotated left. Herein, since thebent portion 231 is formed at one of the first andsecond partition walls upper surface 331 of the other partition wall, it is prevented that the condensate sinks into the bondedsurface 233 of the first andsecond partition walls - Referring to
FIGS. 5 and 6 , in order to help a linkage of the first andsecond cases third grooves second cases third protrusions - Since the
condensate discharging port 600 is formed at thefirst case 1000 a, thesecond groove 120 a is formed to be extended to an end side that thecondensate discharging port 600 starts to be formed, and thesecond protrusion 120 b is formed at thesecond case 1000 b so as to be corresponding to thesecond groove 120 a. - Preferably, the
second groove 120 a and thesecond protrusion 120 b corresponding to thesecond groove 120 a are formed in a desired height from thebottom surface air conditioning case 1000. The desired height is one third of a height of the evaporator E. This is caused by that, even if the condensate is dropped to left and right side surfaces of the evaporator E, it is not apprehended due to a high dropping speed of the condensate that the condensate is leaked through a gap formed at the left and right side walls of theair conditioning case 1000. - Although not shown, in order to prepare for scattering of the condensate when the vehicle travels under bad conditions, the second and
third grooves third protrusions condensate discharging passages - Referring to
FIG. 12 , when the first and secondcondensate discharging passages FIGS. 5 , 6 and 12 show an example in which the first and secondcondensate discharging passages partition condensate discharging passages second cases condensate discharging passages partition condensate discharging passages - Before the drain hose (not shown) is inserted onto outer surfaces of the first and second
condensate discharging passages condensate discharging passages condensate discharging passages condensate discharging passages condensate discharging passages FIG. 15 , ajoint portion 720 of agrommet 800, which is formed with agroove 710, is provided. Thegrommet 800 is inserted onto the outer surfaces of thecondensate discharging passages condensate discharging passages - According to the present invention, since a coupling structure of the left and right cases is improved, it is possible to prevent a leakage of the condensate that is occurred at the evaporator and also to drain the condensate to an outside without a separate lower case, thereby reducing the number of components and work effort for the lower case.
- While the present invention has been described with respect to the specific embodiments, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
