Summary of the Invention

Problems to be Solved by the Invention

[0006] The above ceiling air supply device also has the function of an air purifier by being equipped with a filter for purifying air. Such a filter needs to be replaced regularly with a new one in order to maintain the function as an air purifier. However, since the ceiling air supply device is incorporated between the roof panel and the roof headlining, the roof headlining must be removed when replacing the filter with a new one. Since the work of removing the roof headlining in this way is very time-consuming, maintenance such as replacing the filter to enable the function as an air purifier becomes difficult.

Means for Solving the Problem

[0007] Hereinafter, the means for solving the above problems and their effects will be described. The ceiling air supply device for solving the above problems is arranged between the roof panel and the roof headlining. The ceiling air supply device sucks the air in the vehicle interior by a fan, passes it through the air purifier, and then sends the air to other places in the vehicle interior through a duct arranged between the roof panel and the roof headlining. The ceiling air supply device includes an upper lid, a tray, and a seal member. The upper lid is fixed to the roof panel. The tray is detachably attached to the upper lid through a hole formed in the roof headlining, thereby holding the above fan and the above air purifier between the tray and the upper lid. The seal member is positioned between the upper lid and the tray when the tray is attached to the upper lid, thereby partitioning a passage connecting the air discharge port of the fan and the air inlet of the duct between the upper lid and the tray. The above air purifier is arranged in this passage.

[0008] According to the above configuration, the tray is detachably attached to the upper lid fixed to the roof panel. And the tray can be removed from the upper lid through the hole formed in the roof headlining. By removing the tray from the upper lid in this way, the passage formed between the upper lid and the tray can be vertically divided, so that maintenance such as filter replacement in the air cleaner arranged in the passage becomes possible. And after performing the maintenance of the air cleaner, with the air cleaner arranged between the upper lid and the tray, the tray is attached to the upper lid through the hole of the roof headlining. Thereby, the passage connecting the air outlet of the fan and the inlet of the duct between the upper lid and the tray is partitioned by the sealing member, and the air cleaner is held in the passage. Since maintenance such as filter replacement of the air cleaner can be performed without removing the roof headlining in this way, the maintenance of the air cleaner becomes easier.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, an embodiment of the ceiling air supply device will be described with reference to FIGS. 1 to 5. FIG. 1 shows an enlarged view of the vicinity of the roof panel 12 in the passenger compartment 11 of a vehicle such as an automobile. A roof headlining 13, which is an interior part of the passenger compartment 11, is provided at a position closer to the inside of the passenger compartment 11 than the roof panel 12. A hole 14 is formed in the roof headlining 13. The ceiling air supply device 15 is disposed at a position corresponding to the hole 14 between the roof panel 12 and the roof headlining 13. The ceiling air supply device 15 is for sending the air in the passenger compartment 11 from the front side to the rear side. In FIG. 1, the left side is the front side in the passenger compartment 11, and the right side is the rear side in the passenger compartment 11.

[0011] <Structure of the ceiling air supply device 15> The ceiling air supply device 15 includes an upper lid 16, a tray 17, a fan 18, an air cleaner 19, a seal member 20, and a case 21. The upper lid 16 is fixed to the roof panel 12 by screws or the like. The tray 17 is detachably attached to the upper lid 16. The detachment and attachment of the tray 17 to the upper lid 16 are performed through the hole 14 of the roof headlining 13. By being attached to the upper lid 16, the tray 17 holds the fan 18 and the air cleaner 19 between itself and the upper lid 16. The fan 18 and the air cleaner 19 are attached to the tray 17. Thereby, when the tray 17 is removed from the upper lid 16, the fan 18 and the air cleaner 19 are removed together with the tray 17.

[0012] An intake hole 22 is formed at a position corresponding to the fan 18 in the tray 17. The case 21 is attached to the roof headlining 13 so as to cover the hole 14 from the inside of the passenger compartment 11. The case 21 can be removed with respect to the roof headlining 13. The gap between the tray 17 and the hole 14 is hidden by this case 21. An air inlet 23 is formed at a position corresponding to the hole 14 in the case 21. The fan 18 located between the tray 17 and the upper lid 16 is formed with an inlet 24 for sucking the air in the passenger compartment 11 through the air inlet 23 and the intake hole 22, and an outlet 25 for discharging the sucked air.

[0013] Between the rear end portions of the upper lid 16 and the tray 17, the end portion of a duct 26 disposed between the roof panel 12 and the roof headlining 13 is sandwiched. The inlet 27 of this duct 26 is located at the above-mentioned end portion and opens between the upper lid 16 and the tray 17. The duct 26 is for sending the air discharged from the outlet 25 of the fan 18 to another place in the passenger compartment 11, that is, a place different from the place where the air is sucked into the fan 18. An air purifier 19 for purifying the air by deodorizing, sterilizing, and dust removing the like is disposed between the upper lid 16 and the tray 17, between the outlet 25 of the fan 18 and the inlet 27 of the duct 26.

[0014] <Arrangement of the duct 26 in the passenger compartment 11> FIG. 2 schematically shows a state of the ceiling air supply device 15 and the duct 26 in the passenger compartment 11 as viewed from above. As can be seen from FIG. 2, at the front part of the passenger compartment 11, there is an outlet 28 of the air conditioner in the vehicle. Further, the duct 26 extends from the ceiling air supply device 15 toward the rear side of the passenger compartment 11. An end of the duct 26 opposite to the inlet 27 serves as an outlet 29. The outlet 29 of the duct 26 is open to the inside of the passenger compartment 11. The conditioned air from the air conditioner is blown into the passenger compartment 11 from the above-described outlet 28. In order to prevent this conditioned air from being biased to the front part in the passenger compartment 11, the air in the passenger compartment 11 is sent to the duct 26 by the ceiling air supply device 15. The air sent from the ceiling air supply device 15 to the duct 26 is led out from the outlet 29 through the duct 26 to the rear part in the passenger compartment 11.

[0015] <Connection structure between the fan 18 of the ceiling air supply device 15 and the duct 26> As shown in FIGS. 3 and 4, the upper lid 16 and the tray 17 are formed in a rectangular plate shape. A plurality of pedestals 30 are formed on the long sides of the outer edge of the tray 17. Clips 31 are respectively fixed to the pedestals 30. A hole forming portion 32 is formed at a position on the upper lid 16 corresponding to the pedestal 30 of the tray 17. A hole 33 is formed in the hole forming portion 32, and the clip 31 is detachably attached to the hole 33. Then, through the attachment of the clip 31 to the hole 33, the tray 17 is detachably attached to the upper lid 16.

[0016] On the surface of the tray 17 facing the upper lid 16, a standing wall 34 and a partition wall 35 protruding toward the upper lid 16 are formed. The standing wall 34 extends so as to form a rectangular frame shape. The partition wall 35 extends so as to connect the long sides of the standing wall 34 at the center in the long side direction of the standing wall 34. On the surface of the upper lid 16 facing the tray 17, a standing wall 36 and a partition wall 37 protruding toward the tray 17 are formed. The standing wall 36 extends so as to form a rectangular frame shape corresponding to the above-described standing wall 34. The partition wall 37 extends so as to connect the long sides of the standing wall 36 at the center in the long side direction of the standing wall 36 so as to be positioned corresponding to the above-described partition wall 35.

[0017] The vertical walls 34, 36 and the partition walls 35, 37 are for partitioning a storage chamber 38 and a passage 40 between the upper lid 16 and the tray 17 when the tray 17 is attached to the upper lid 16. A fan 18 is stored in the storage chamber 38. The intake holes 22 of the tray 17 shown in FIG. 1 are connected to the intake port 24 of the fan 18 by being positioned corresponding to the storage chamber 38. The discharge port 25 of the fan 18 is surrounded by the partition wall 35 and the partition wall 37. The discharge port 25 is connected to the passage 40. An air cleaner 19 is arranged in the passage 40. Further, an inlet 27 of a duct 26 is connected to the passage 40. The inlet 27 is surrounded by the end portion near the duct 26 on the vertical wall 34 and the end portion near the duct 26 on the vertical wall 36.

[0018] <Sealing structure of the storage chamber 38 and the passage 40> The storage chamber 38 and the passage 40 shown in FIGS. 3 and 4 are sealed by a seal member 20. The seal member 20 includes an outer frame portion 41, a partition portion 42, and upper edge portions 43, 44. The outer frame portion 41 is attached to the tip of the vertical wall 34 in the protruding direction with respect to the tray 17. The partition portion 42 is attached to the tip of the partition wall 35 in the protruding direction with respect to the tray 17. The upper edge portion 43 is attached to a position corresponding to the discharge port 25 of the fan 18 on the partition wall 37. The upper edge portion 44 is attached to a position corresponding to the inlet 27 of the duct 26, which is the end portion near the duct 26 on the vertical wall 36.

[0019] When the tray 17 is attached to the upper lid 16, the outer frame portion 41 of the seal member 20 is sandwiched between the vertical wall 34 of the tray 17 and the vertical wall 36 of the upper lid 16. At this time, the inlet 27 in the duct 26 is surrounded by the outer frame portion 41 and the upper edge portion 44 of the seal member 20 as shown in FIG. 5. Further, the partition portion 42 of the seal member 20 is sandwiched between the partition wall 35 of the tray 17 and the partition wall 37 of the upper lid 16 shown in FIGS. 3 and 4, and the periphery of the discharge port 25 of the fan 18 is surrounded by the partition portion 42 and the upper edge portion 43 of the seal member 20.

[0020] As a result, when the tray 17 is attached to the upper lid 16, the seal member 20 positioned between the standing walls 34 and partition wall 35 of the tray 17 and the standing walls 36 and partition wall 37 of the upper lid 16 partitions the storage chamber 38 and the passage 40 between the upper lid 16 and the tray 17. Specifically, the seal member 20 partitions the storage chamber 38 and the passage 40 from each other and also partitions the storage chamber 38 and the passage 40 from the outside of the ceiling air supply device 15. The passage 40 thus partitioned connects the discharge port 25 of the fan 18 and the inlet 27 of the duct 26.

[0021] <Operation of the ceiling air supply device 15> When the fan 18 of the ceiling air supply device 15 shown in FIG. 1 is driven, the air in the front part of the passenger compartment 11 is sucked into the suction port 24 of the fan 18 through the air intake 23 of the case 21 and the intake holes 22 of the tray 17. The air thus sucked is discharged from the discharge port 25 of the fan 18 into the passage 40, and after being purified by the air purifier 19 when passing through the passage 40, it is introduced into the inlet 27 of the duct 26. This air is led out from the outlet 29 through the duct 26 to the rear part of the passenger compartment 11. By sending the air in the front part of the passenger compartment 11 to the rear part of the passenger compartment 11 using the ceiling air supply device 15 in this way, the conditioned air blown out from the outlet 28 of the air conditioner is less likely to be biased to the front part of the passenger compartment.

[0022] Next, the operation and effects of the ceiling air supply device 15 of the present embodiment will be described. (1) The upper lid 16 of the ceiling air supply device 15 is fixed to the roof panel 12 in the passenger compartment 11 of the vehicle. The tray 17 of the ceiling air supply device 15 is detachably attached to the upper lid 16. Also, the case 21 is detachably attached to the roof headlining 13. And the tray 17 can be removed from the upper lid 16 through the hole 14 formed in the roof headlining 13 in a state where the case 21 is removed from the roof headlining 13.

[0023] By removing the tray 17 from the upper lid 16 in this way, the passage 40 formed between the upper lid 16 and the tray 17 can be vertically divided, so that maintenance such as filter replacement of the air cleaner 19 arranged in the passage 40 becomes possible. After performing the maintenance of the air cleaner 19, with the air cleaner 19 arranged between the upper lid 16 and the tray 17, the tray 17 is attached to the upper lid 16 through the hole 14 of the roof head lining 13. Thereby, the passage 40 connecting the discharge port 25 of the fan 18 and the inlet port 27 of the duct 26 between the upper lid 16 and the tray 17 is partitioned by the seal member 20, and the air cleaner 19 is held in the passage 40. Then, the case 21 is attached to the roof head lining 13 so as to close the hole 14.

[0024] In this ceiling air supply device 15, as described above, maintenance such as filter replacement of the air cleaner 19 can be performed without removing the roof head lining 13, so that the maintenance of the air cleaner 19 becomes easy.

[0025] (2) The air cleaner 19 is attached to the tray 17 and is removed together with the tray 17 when the tray 17 is removed from the upper lid 16. Therefore, since the air cleaner 19 can be removed from the ceiling air supply device 15 only by removing the tray 17 from the upper lid 16, maintenance such as filter replacement of the air cleaner 19 can be performed more easily.

[0026] (3) The fan 18 is attached to the tray 17 and is removed together with the tray 17 when the tray 17 is removed from the upper lid 16. Therefore, since the fan 18 can be removed from the ceiling air supply device 15 only by removing the tray 17 from the upper lid 16, the maintenance of the fan 18 can be easily performed.

[0027] (4) The ceiling air supply device 15 includes a case 21 that is attached to the roof headlining 13 so as to cover the hole 14 in the roof headlining 13 from the passenger compartment 11 side, with the tray 17 attached to the upper lid 16. An air intake 23 that connects to the air suction port 24 of the fan 18 of the ceiling air supply device 15 is formed in this case 21. When the tray 17 is attached to the upper lid 16, a gap is generated between the tray 17 and the hole 14 in the roof headlining 13. Regarding such a gap, it can be hidden by attaching the case 21 to the roof headlining 13 so as to cover the hole 14 in the roof headlining 13 from the passenger compartment 11 side. Also, in this case, functions such as lamps and switches can be provided in the case 21.

[0028] In addition, the above embodiment can be modified as follows, for example. The above embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range. · The case 21 may be omitted as shown in FIG. 6. In this case, it is conceivable to form a flange 45 at the outer edge of the tray 17 to cover the space between the hole 14 in the roof headlining 13 and the tray 17 when the tray 17 is attached to the upper lid 16. In this case, when the tray 17 is attached to the upper lid 16, the gap between the tray 17 and the hole 14 in the roof headlining 13 can be hidden by the flange 45. Also, since it is not necessary to remove and attach the case 21 to the roof headlining 13, the work of removing and attaching the tray 17 to the upper lid 16 during maintenance of the air cleaner 19 etc. becomes easier.

[0029] · The fan 18 may be attached to the upper lid 16. In this case, when the tray 17 is removed from the upper lid 16, the fan 18 is in a state of being attached to the upper lid 16. · The air cleaner 19 may be attached to the upper lid 16. In this case, when the tray 17 is removed from the upper lid 16, the air cleaner 19 is in a state of being attached to the upper lid 16.

[0030] · When the tray 17 is removed from the upper lid 16, the fan 18 may be disposed between the upper lid 16 and the tray 17 so as to be able to move relative to the upper lid 16 and the tray 17 freely.

[0031] · When the tray 17 is removed from the upper lid 16, the air cleaner 19 may be disposed between the upper lid 16 and the tray 17 so as to be able to move relative to the upper lid 16 and the tray 17 freely.

[0032] Next, the technical idea that can be grasped from the above embodiment will be described. (A) In a ceiling air supply device that is disposed between a roof panel and a roof headlining, sucks air in the vehicle interior by a fan, passes the air through an air cleaner, and then sends the air to another place in the vehicle interior through a duct disposed between the roof panel and the roof headlining, comprising an upper lid, a tray, and a seal member, the upper lid is fixed to the roof panel, the tray is removably attached to the upper lid through a hole formed in the roof headlining, thereby holding the fan and the air cleaner between the tray and the upper lid, the seal member is positioned between the upper lid and the tray when the tray is attached to the upper lid, thereby partitioning a passage connecting the air discharge port of the fan and the air inlet of the duct between the upper lid and the tray, the ceiling air supply device in which the air cleaner is disposed in the passage.
