Description

  The present invention relates to a condensate drainage structure in an air conditioner in which air flows through a cooling heat exchanger disposed substantially horizontally from below to above.

  Conventionally, in a vehicle air conditioner, in order to reduce a vehicle mounting space, a cooling heat exchanger is arranged substantially horizontally so that blown air flows from below to above the cooling heat exchanger. An arrangement configuration is known (for example, see Patent Document 1).

  And in patent document 2, the drainage structure for improving the drainage property of condensed water is proposed in this kind of horizontal installation type vehicle air conditioner. Specifically, the cooling heat exchanger is disposed at a slight angle with respect to the horizontal plane, and the partition rib and the drainage rib are integrally molded with resin at a position below the inclined lower end of the cooling heat exchanger. A drainage rib member having a shape is arranged. The drainage rib is located on the lower side of the cooling heat exchanger than the partition rib, and both the partition rib and the drainage rib have a plate shape extending in a direction orthogonal to the direction of the cooling heat exchanger. Yes.

  And the drainage seal part which consists of elastic materials is fixed to the upper end part of a partition rib and a drainage rib, and this drainage seal part is made to contact the lower surface part of the tank part of the heat exchanger for cooling. The partition rib plays a role of partitioning the lower space of the cooling heat exchanger into a blower space and a drainage space.

  Here, the air blowing space is a space located on the inclined upper side (heat exchange core portion side) of the cooling heat exchanger with respect to the partition rib, and the drainage space is more of the cooling heat exchanger than the partition rib. It is a space located on the inclined lower side (tank portion side).

Thereby, since the drainage rib is located in the drainage space, the air flow in the ventilation space does not directly blow against the drainage rib. As a result, the condensed water collected in the tank portion located at the inclined lower end of the cooling heat exchanger can be smoothly dropped downward along the surface of the second drainage rib without being blown up by the wind pressure of the blown air. Can do.

  However, in the prior art of Patent Document 2, since the drain seal part is separately fixed to the partition rib of the drain rib member and the upper end of the drain rib, the number of parts is increased, the assembly is complicated, and the cost is increased. Invite.

  In view of the above points, an object of the present invention is to improve the assembly of a condensate drainage structure in an air conditioner in which air flows from a lower side to an upper side in a cooling heat exchanger arranged substantially horizontally.

The present invention has been devised to achieve the above object, and is disposed substantially horizontally, and the drainage guide member (16, 17) is disposed at a lower portion of the cooling heat exchanger (12) through which air passes from below to above. 20)
This drainage guide member is fixed to the upper ends of the plurality of drainage ribs (16, 17) and the plurality of drainage ribs (16, 17) provided in the air conditioning case (11), and the cooling heat exchanger ( 12) and a plurality of drainage seal portions (21, 22) in contact with the surface,
The plurality of drainage seal portions (21, 22) are integrally connected by the connection portion (23), and the plurality of drainage seal portions (21, 22) and the connection portion (23) are integrally formed of an elastic material. It is a feature.

  According to this, since the plurality of drainage seal portions (21, 22) can be configured as one integral molded part, the plurality of drainage seal portions (21, 22) can be configured as a plurality of drainage ribs (16, 17) by one assembling operation. It can be fixed to the upper end of Therefore, the assembly workability can be improved and the cost can be reduced.

  In addition, since the plurality of drain seal portions (21, 22) are integrally connected by the connecting portion (23), the assembly of the plurality of drain seal portions (21, 22) at the upper ends of the plurality of drain ribs (16, 17). It is easy to set the posture to the normal position. For this reason, the plurality of drainage seal portions (21, 22) can be reliably brought into close contact with the surface of the cooling heat exchanger (12).

  The “substantially horizontal arrangement” of the cooling heat exchanger (12) is meant to include both the horizontal arrangement and the arrangement inclined by a minute angle from the horizontal plane.

Specifically, in the present invention, the cooling heat exchanger (12) is disposed so as to be inclined at a minute angle from the horizontal plane, and the drainage guide member ( 16, 17, 20)
What is necessary is just to arrange | position a some drainage rib (16, 17) and a some drainage seal part (21, 22) so that it may extend in the direction orthogonal to the inclination direction of the heat exchanger for cooling (12).

  According to this, the condensed water gathering on the inclined lower end side of the heat exchanger for cooling (12) can be smoothly drained through the plurality of drain seal portions (21, 22) and the plurality of drain ribs (16, 17).

In the present invention, more specifically, the cooling heat exchanger (12) includes a heat exchange core portion (12a) through which air passes from below to above, and a refrigerant for a tube of the heat exchange core portion (12a). A tank section (12b) for distributing or collecting refrigerant,
The cooling heat exchanger (12) is inclinedly arranged so that the tank part (12b) is located on the inclined lower end side,
You may make it make a some drainage seal part (21, 22) contact the lower surface of a tank part (12b).

  According to this, the condensed water gathered on the lower surface of the tank part (12b) located on the inclined lower end side of the cooling heat exchanger (12) is separated from the plurality of drain seal parts (21, 22) and the plurality of drain ribs (16 17) can be drained smoothly.

In the present invention, the cooling heat exchanger (12) is inclined so that the tank portion (12b) is positioned on the inclined lower end side as described above, and among the plurality of drain seal portions (21, 22). , One drain seal part (21) is in contact with the part closer to the heat exchange core part (12a) than the boundary part between the heat exchange core part (12a) and the tank part (12b),
Of the plurality of drain seal portions (21, 22), the other drain seal portion (22) may be in contact with the lower surface of the tank portion (12b).

  According to this, as illustrated in the broken line arrow B ′ in FIG. 5 described later, the blown air is sent to the boundary portion of the heat exchange core portion (12a) by the one drain seal portion (21) and the one drain rib (16). Since it guides upwards in front, it can prevent that the wind pressure of blowing air acts on the condensed water concentration part (24) formed near this boundary part. Thereby, the condensed water of a condensed water concentration part (24) can be drained much more smoothly.

  In addition, the code | symbol in the bracket | parenthesis of each said means and each means of a claim shows the correspondence with the specific means as described in embodiment mentioned later.

(First embodiment)
1 to 4 show a first embodiment of the present invention. FIG. 1 is a sectional view of a main part of an indoor air conditioning unit 10 of a vehicle air conditioner. FIG. It is a principal part perspective view of a side division | segmentation case. The top, bottom, left and right arrows in FIGS. 1 and 2 indicate directions in the vehicle-mounted state of the present embodiment.

  Since the overall configuration of the indoor air conditioning unit 10 is the same as that of Patent Document 2 (Japanese Patent Laid-Open No. 11-115471), an outline thereof will be described first. The indoor air-conditioning unit 10 is mounted at the center in the vehicle left-right (width) direction inside the instrument panel (instrument panel) disposed at the foremost part in the vehicle interior.

  In addition, the air blower unit (not shown) of the air conditioner is arranged offset from the center inside the instrument panel to the passenger seat side with respect to the indoor air conditioner unit 10. Since this embodiment shows an example of mounting on a right-hand drive vehicle, the blower unit is offset from the indoor air conditioning unit 10 to the left side.

  The air conditioning case 11 of the indoor air conditioning unit 10 is a resin molded product. In this embodiment, the air conditioning case 11 is divided into a lower divided case 11a and an upper divided case 11b. Although the upper divided case 11b is not shown, it is actually divided into two right and left divided cases.

  The evaporator 12 is a cooling heat exchanger that cools the air blown from the blower unit, and is housed in a lower portion of the air conditioning case 11 on the lower divided case 11a side. Here, the evaporator 12 is inclined substantially by a minute angle θ (for example, about 10 to 30 °) from the horizontal plane and is disposed substantially horizontally.

  In the present embodiment, the evaporator 12 is disposed in an inclined manner so that the vehicle front-rear direction, specifically, the vehicle front side is high and the rear side is low. On the other hand, the air blown from the blower unit flows from the vehicle left-right direction A toward the lower space 13 of the evaporator 12. Therefore, the inclination direction of the evaporator 12 is a direction orthogonal to the air inflow direction A.

  As is well known, the evaporator 12 has a heat exchange core portion 12a composed of a combination of a number of flat tubes (not shown) constituting the refrigerant passage and fins such as corrugated fins, and this heat exchange core portion. The tank portion 12b is arranged at both ends of the tube 12a in the longitudinal direction (left-right direction in FIG. 1).

  The tank portion 12b performs refrigerant distribution to the tubes or collects refrigerant from the tubes. In FIG. 1, only the tank portion 12b on one side is shown. The tank part 12b on one side is located at the inclined lower end part of the evaporator 12, and the tank part on the other side (not shown) is located at the inclined upper end part of the evaporator 12.

  The blown air that has flowed into the lower space 13 of the evaporator 12 flows upward from below through the gap between the tubes and the fins of the heat exchange core 12a of the evaporator 12 as indicated by the arrow B.

  In the lower divided case 11a, a water collecting portion 14 having the lowest height in the top-and-bottom direction is formed on the lower side of the tank portion 12b that is the inclined lower end portion of the evaporator 12. The water collecting part 14 plays a role of collecting condensed water. A drainage port 15 is opened in the water collecting part 14, and the condensed water can be discharged out of the passenger compartment through the drainage port 15.

  A first drainage rib 16 and a second drainage rib 17 are arranged in parallel in the area of the water collecting portion 14 in the bottom surface portion in the lower divided case 11a. The first and second drainage ribs 16 and 17 are plate-like members protruding upward from the surface of the water collecting portion 14 (inner wall surface of the case bottom portion) of the lower divided case 11a, and evaporate as shown in FIG. The plate 12 is integrally formed with the lower divided case 11a in a plate shape extending over the entire width direction of the vessel 12. The width direction of the evaporator 12 is the tube stacking direction of the heat exchange core portion 12a (the direction perpendicular to the paper surface of FIG. 1). In this embodiment, the width direction of the evaporator 12 is the vehicle left-right direction.

  The first and second drainage ribs 16 and 17 are formed with drainage portions 18 and 19 that allow the condensed water falling on the bottom surface of the lower divided case 11a to move to the drainage port 15 side. Here, the drainage parts 18 and 19 are specifically formed in the shape of the notch groove extended in an up-down direction. However, instead of this notch groove shape, a through hole that allows the movement of condensed water is formed at the bottom of the first and second drainage ribs 16 and 17, and the drainage portions 18 and 19 are formed in this through hole. May be.

  Drain seal portions 21 and 22 of an integrated drain seal member 20 made of an elastic material are respectively attached and fixed to the upper ends of the first and second drain ribs 16 and 17. The drainage seal portions 21 and 22 have a plate-like shape extending along the evaporator width direction as shown in FIG. And the beam-like connection part 23 is formed in the several places of an evaporator width direction, and the two drainage seal parts 21 and 22 are integrally connected by this beam-like connection part 23. FIG.

  Thereby, the integral drainage seal member 20 is formed as one integral part having the two drainage seal portions 21 and 22 and the beam-like connecting portion 23. Here, a thermoplastic elastomer is suitable as a specific material of the integrated drainage seal member 20. This thermoplastic elastomer exhibits rubber elasticity at room temperature, while it melts and exhibits fluidity when heated at high temperatures, and can be injection-molded in the same manner as a thermoplastic resin.

  The integrated drainage seal member 20 is formed as a separate member from the lower divided case 11 a and then attached to the upper ends of the first and second drainage ribs 16 and 17. More specifically, as shown in FIG. 3 and FIG. 4A, clamping portions 21 a and 22 a having a U-shaped cross section are formed below the drainage seal portions 21 and 22, respectively. The inner width dimensions of 21a and 22a are designed to be slightly smaller than the plate thickness of the first and second drainage ribs 16 and 17.

  As a result, the sandwiching portions 21a and 22a having a U-shaped cross section can be fitted and attached to the upper end portions of the first and second drainage ribs 16 and 17 in an elastically pressed state. 1. It can fix to the upper end part of the 2nd drainage ribs 16 and 17.

  As shown in FIGS. 1 and 4A, the tank portion 12 b located at the inclined lower end portion of the evaporator 12 is provided with first and second drainage via the drainage seal portions 21 and 22 of the integrated drainage seal member 20. It is placed on the ribs 16 and 17 and supported by the first and second drainage ribs 16 and 17. Accordingly, the first and second drainage ribs 16 and 17 also serve as support members for the evaporator 12.

  Further, since a compressive load is applied to the drainage seal portions 21 and 22 due to the weight of the evaporator 12, the drainage seal portions 21 and 22 are elastically compressed and deformed. For this reason, the upper end surfaces of the drainage seal portions 21 and 22 are in close contact with the lower surface of the tank portion 12b.

  Specifically, the tank part 12b of the present embodiment is divided into an upper tank part 12b-1 and a lower tank part 12b-2, and between the upper and lower tank parts 12b-1, 12b-2. A water drainage passage 12b-3 is formed in the bottom. This drain passage 12b-3 is formed at a plurality of locations in the evaporator width direction.

  Note that a heating heat exchanger, a temperature adjusting air mix door, a blowing mode switching mechanism, and the like (not shown) are arranged on the upper side of the evaporator 12 as in Patent Document 2.

  Next, the operation of this embodiment in the above configuration will be described. When an electric blower of a blower unit (not shown) is actuated, a direction A in which blown air (outside air or inside air) of the blower is perpendicular to the inclination direction of the evaporator 12 in the lower space 13 of the evaporator 12 inside the air conditioning case 11. It flows from (vehicle left-right direction).

  The inflowing air changes direction in the lower space 13 and passes through the heat exchange core portion 12a of the evaporator 12 from the lower side to the upper side as indicated by the arrow B. As a result, the air is cooled by heat exchange with the low-pressure refrigerant passing through the tube of the heat exchange core portion 12a to become cold air, and this cold air is blown out into the vehicle interior to cool the vehicle interior.

  By the way, since the moisture in the air is condensed by the cooling action in the heat exchange core part 12a of the evaporator 12, condensed water is generated on the tubes and fin surfaces of the heat exchange core part 12a. Since the blown air passes from the lower side to the upper side through the gap between the tube and the fin of the heat exchange core part 12a, the upward wind pressure acts on the condensed water on the surface of the heat exchange core part 12a.

  Therefore, most of the condensed water on the surface of the heat exchange core part 12a does not immediately drop downward, but along the tube surface of the heat exchange core part 12a, the tank part 12b side at the inclined lower end of the evaporator 12 (right side in FIG. 1). Move to. That is, since the tube longitudinal direction of the heat exchange core portion 12a is directed to the inclination direction of the evaporator 12, most of the condensed water moves to the inclined lower end side of the evaporator 12 along the tube surface.

  As a result, the condensed water concentration portion 24 is formed in the vicinity of the lower portion of the boundary portion between the heat exchange core portion 12a and the tank portion 12b on the inclined lower end side. The condensed water of the condensed water concentration part 24 falls on the bottom surface of the lower divided case 11a along the surfaces of the first drain seal part 21 and the first drain ribs 16 as indicated by an arrow C.

  The condensed water dropped on the bottom surface of the lower divided case 11a passes through the drainage portions 18 and 19 of the first and second drainage ribs 16 and 17, and the lowermost water collecting portion 14 of the lower divided case 11a, It flows to the drain port 15.

  On the other hand, the condensed water that has reached the upper side of the condensed water concentration portion 24, that is, the vicinity of the boundary portion 25 with the upper tank portion 12b-1 in the heat exchange core portion 12a, is shown in FIG. It passes through the drain passage 12b-3 between 12b-1 and 12b-2, and moves downward along the outer surface of the lower tank portion 12b-2. This condensed water further falls on the water collecting portion 14 of the lower divided case 11 a along the surfaces of the second drain seal portion 22 and the second drain rib 17 and is drained from the drain port 15.

  In addition, since the surface of the tank part 12b has a complicated uneven shape, a minute gap may be formed between the first drain seal part 21 on the first drain rib 16 side and the surface of the tank part 12b. In this case, a part of the condensed water in the condensed water concentration part 24 may pass through this minute gap (leakage passage) and flow into the intermediate part between the first and second drain seal parts 21 and 22.

  The condensed water can pass through gaps formed between the plurality of beam-like connecting portions 23 and fall downward, and passes through the drainage portions 19 of the second drainage ribs 17 to the drainage port 15. And flow.

  Moreover, before a part of the condensed water generated on the surface of the heat exchange core portion 12a reaches the vicinity of the boundary portion 25 with the condensed water concentration portion 24 or the upper tank portion 12b-1, the bottom surface of the lower divided case 11a is May fall. This condensed water passes through the drainage portions 18 and 19 of the first and second drainage ribs 16 and 17 together with the condensed water falling along the path indicated by the arrow C and flows to the drainage port 15.

  By the way, according to this embodiment, since the integral drainage seal member 20 is formed as one integral part having the two drainage seal portions 21 and 22 and the beam-like connecting portion 23, the two drainage seal portions 21, 22 can be assembled to the upper ends of the first and second drainage ribs 16 and 17 at a time. Therefore, the assembling property of the drain seal parts 21 and 22 can be improved.

  Moreover, since the two drainage seal portions 21 and 22 are integrally connected by the connecting portion 23, the assembly posture of the two drainage seal portions 21 and 22 at the upper end portions of the first and second drainage ribs 16 and 17 is set. It is easy to set the normal position. Therefore, the two drain seal parts 21 and 22 can be securely adhered to the lower surface of the tank part 12b.

  In this embodiment, as shown in FIG. 4 (a), sandwiched portions 21a and 22a having a U-shaped cross section are formed below the two drainage seal portions 21 and 22, respectively. 21a and 22a are fitted and mounted on the upper end portions of the first and second drainage ribs 16 and 17 in an elastically press-contact state, whereby the integrated drainage seal member 20 is fitted to the upper end portions of the first and second drainage ribs 16 and 17. However, as shown in FIG. 4 (b), only the first drainage seal portion 21 is formed with a clamping portion 21 a having a U-shaped cross section, and the integrated drainage seal member 20 is connected to the upper end of the first drainage rib 16. You may make it fix to a part.

  Further, as shown in FIG. 4C, a sandwiching portion 22 a having a U-shaped cross section is formed only in the second drainage seal portion 22 so that the integrated drainage seal member 20 is fixed to the upper end portion of the second drainage rib 17. It may be.

(Second Embodiment)
In the first embodiment, the two drain seal parts 21 and 22 are both brought into pressure contact with the lower surface of the tank part 12b. In the second embodiment, the evaporator 12 of the two drain seal parts 21 and 22 is used. As shown in FIG. 5 and FIG. 7A, heat exchange is performed on the positions of the first drain seal portion 21 and the first drain ribs 16 located on the heat exchange core portion 12a side (the inclined upper side of the evaporator 12). The evaporator 12 is positioned above the inclination of the evaporator 12 relative to the boundary between the core 12a and the tank 12b.

  Thereby, in 2nd Embodiment, only the 2nd drainage seal part 22 press-contacts to the lower surface of the tank part 12b. Accordingly, as shown in FIG. 6, the upper part of the second drainage seal portion 22 has a plurality of branch portions in the tank thickness direction (left and right directions in FIGS. 5 and 6), specifically, three branch portions 22b and 22c. , 22d.

  According to the second embodiment, the first drain seal part 21 and the first drain rib 16 are located on the upper side of the evaporator 12 with respect to the boundary between the heat exchange core part 12a and the tank part 12b of the evaporator 12. Since the upper end portion of the first drainage rib 16 is in pressure contact with the inclined lower end portion of the heat exchange core portion 12a of the evaporator 12, the air passing through the heat exchange core portion 12a is indicated by a broken line arrow B ′ in FIG. In addition, the first drain seal portion 21 and the first drain rib 16 guide it upward before the boundary portion.

  Thereby, the wind pressure of the airflow which goes to the upper part from the downward | lower direction does not act directly on the condensed water concentration part 24 formed in the lower part of the said boundary part. As a result, the condensate in the condensate concentration part 24 is transmitted through the front branch part 22b at the upper part of the second drainage seal part 22 as shown by the arrow C without being disturbed by this wind pressure, and between the connecting parts 23 It can pass smoothly through the voids and fall downward.

  Moreover, the condensed water which reached | attained the boundary part 25 vicinity with the upper side tank part 12b-1 among the heat exchange core parts 12a is water between the upper and lower tank parts 12b-1 and 12b-2 like the arrow D. It passes through the extraction passage 12b-3 and moves downward along the outer surface of the lower tank portion 12b-2. This condensed water can further drop smoothly down along the surface of the rear branching portion 22d and the second drainage rib 17 on the second drainage seal portion 22.

  In addition, although the central branch part 22c of the upper part of the 2nd drainage seal part 22 has played the role which supports the tank part 12b, the center branch part 22c is abolished and between the front side branch part 22b and the rear side branch part 22d. The tank portion 12b may be supported by a curved surface.

  Moreover, in 2nd Embodiment, the structure which fixes the integrated drainage sealing member 20 to the upper end part of the 1st, 2nd drainage ribs 16 and 17 can be changed as shown to FIG.7 (b) (c). This is the same as in the first embodiment.
