Description

  The present invention relates to a console box installed in a vehicle, for example, between a driver seat and a passenger seat.

Conventionally, as this type of console box, for example, one having a configuration as disclosed in the following patent documents is known. That is, the console box of Patent Document 1 includes a storage compartment (loading room). On both sides of the storage compartment are ducts through which conditioned air flows for ventilation at the rear of the vehicle. Both side portions of the front wall of the storage compartment are formed in a circular arc shape that is curved inward, and air inlets that communicate with the inside of the duct are formed therethrough. A slider for closing each air inlet is disposed in the storage compartment. On the other hand, the duct is expanded in a duct section provided upstream of the air inlet. A part of the conditioned air flowing in the duct flows into the duct section and then into the storage compartment from the air inlet. Further, in the configuration described in Patent Document 2, the console box includes a recess for storing the stored items, and the recess is partitioned by a support member having a square plate shape.
JP 2001-63350 A JP-A-10-315863

However, the conventional configuration has the following problems.
That is, in the configuration described in Patent Document 1, the capacity of the storage compartment is small because both sides of the front wall of the storage compartment are formed in a circular arc shape that curves inward. For this reason, there has been a problem that the amount of storage items that can be stored in the storage compartment, that is, the storage amount is small. Furthermore, when each air inlet is closed by the slider, the conditioned air that has circulated in the duct section collides with the slider and does not flow into the storage compartment. The conditioned air that collides with the slider is pushed back into the duct by the conditioned air newly flowing into the duct section. For this reason, there is a problem that the conditioned air in the duct is disturbed by the conditioned air pushed back into the duct and cannot smoothly flow.

  The present invention has been made paying attention to such problems existing in the prior art. The purpose is to allow the conditioned air in the duct to flow efficiently into the storage body to exert heat insulation or cooling function, increase the storage capacity in the storage body, and further smooth the conditioned air in the duct. It is to provide a console box that can be distributed.

In order to achieve the above object, the invention described in claim 1 is a storage body having a bottomed square box shape, a lid that closes an upper surface opening of the storage body so as to be openable and closable, and a longitudinal direction of the storage body. A duct disposed adjacent to the extending side wall and through which the conditioned air flows from the front to the rear of the vehicle, and an air outflow hole that is located at the rear end of the duct and allows the conditioned air to flow into the vehicle interior, the front wall and both side walls of the container is formed by a flat plate, above the front end position of the side walls of the container which is disposed adjacent to the duct, flowing the conditioned air toward the housing body through the duct An air inflow hole is provided, and a blowout hole for blowing the air in the storage body into the vehicle interior is provided in the center of the rear wall of the storage body, and air conditioning to the vehicle interior is provided between the air inflow hole and the air outflow hole. An air outflow adjusting member that adjusts the outflow amount of air is provided.

  Therefore, when the rear of the air inflow hole in the duct is blocked by the air outflow adjusting member, the conditioned air in the duct efficiently flows into the housing body from the air inflow hole, and the heat insulation or cold insulation function can be enhanced. Furthermore, since the storage body is formed in a bottomed square box shape and the front wall and both side walls of the storage body are formed of flat plates, the capacity of the storage body increases. In addition, since the air inflow hole is provided in the side wall of the storage body, the flow direction of the conditioned air in the duct and the inflow direction into the storage body are orthogonal to each other. For this reason, the conditioned air in the duct is circulated smoothly.

Furthermore , since the air inflow hole is provided at the front end portion of the side wall of the storage body and the blowout hole is provided in the rear wall of the storage body, the conditioned air can easily flow through the entire storage body. Furthermore, the conditioned air in the storage body can be circulated from the front to the rear of the storage body. For this reason, it is suppressed that the air-conditioning air which flowed in the storage body returns in a duct, and the air-conditioning air in a duct is distribute | circulated more smoothly.

The invention according to claim 2 is characterized in that, in the invention according to claim 1, a partition plate for partitioning the interior of the storage body in the front-rear direction is provided in the storage body positioned behind the air inflow hole. To do.

  Therefore, since the storage body is partitioned in the front-rear direction behind the air inflow hole, the heat insulation or cold insulation efficiency in the front of the storage body can be improved, and the heat insulation or cold insulation function can be locally enhanced.

  According to the present invention, the conditioned air in the duct can be efficiently allowed to flow into the storage body to perform a heat insulation or cold insulation function, the storage amount in the storage body can be increased, and the conditioned air in the duct can be smoothly supplied. It can be distributed.

Hereinafter, an embodiment embodying the present invention will be described.
As shown in FIGS. 1 and 2, the console box 11 is disposed between the driver seat and the passenger seat so that the longitudinal direction extends along the front-rear direction of the vehicle. The front end portion of the console box 11 is connected to a center panel (not shown) disposed in the center of the front end portion in the vehicle compartment. At the rear end of the console box 11 is provided a box body 11a formed of a synthetic resin in a covered rectangular box shape. A storage body 12 formed in the shape of a bottomed rectangular box for storing storage items is provided in the box body 11a (in the center).

  As shown in FIGS. 2 and 3A, a pair of side panels 13 extending in the vehicle front-rear direction are provided on the left and right sides of the box body 11a. A rear panel 14 extending in the vehicle width direction is provided at the rear end of the box body 11a. At the upper end of the box body 11a, there is provided a lid 15 that has a rectangular plate shape and closes the upper surface opening of the storage body 12 so that it can be opened and closed. The pair of side panels 13 are disposed so as to be spaced apart from the left and right side walls 12a of the storage body 12 at a predetermined interval and to extend in parallel to the side walls 12a. The lid body 15 is pivotally mounted so as to rotate in the vertical direction around the rear end portion, and closes the upper surface opening of the storage body 12 so that it can be opened and closed.

  As shown in FIGS. 1A and 2, the front wall 12 b and the left and right side walls 12 a of the storage body 12 are each formed by a flat rectangular plate. A plurality of air inflow holes 16 formed in the shape of an oblong square hole extending in the vertical direction are provided at predetermined positions above the front end portion of each side wall 12a. A blowout cylinder 17 formed in a square cylinder shape is provided at the center of the lower portion of the rear wall 12c of the storage body 12 so as to extend rearward of the vehicle. The rear end of the blowing cylinder 17 is a first RF register 18 as a blowing hole.

  A pair of ducts 19 formed in a rectangular tube shape extending in the front-rear direction of the vehicle are provided on both left and right sides of the box body 11a. The front end of each duct 19 is connected to an air conditioner (not shown). The rear end portion of the duct 19 is disposed between the upper portion of the storage body 12 and the upper portion of the side panel 13 and is formed to extend linearly in the vehicle front-rear direction. Further, the left and right side surfaces of the rear end portion of the duct 19 are constituted by the side wall 12 a and the side panel 13 of the storage body 12. The duct 19 communicates with the inside of the housing body 12 through the air inflow hole 16.

  The rear end of the duct 19 is a second RF register 20 as an air outflow hole. The second RF resistor 20 is open at one side of the rear panel 14. A shut damper 21 as an air outflow adjusting member for adjusting the outflow amount of the conditioned air into the vehicle interior is attached to the rear end portion of the duct 19 positioned slightly in front of the second RF register 20. The shut damper 21 is formed of a synthetic resin material in the shape of a square plate having the same shape as the normal cross section of the duct 19, and the flow of conditioned air flowing out from the second RF register 20 into the vehicle compartment can be opened and closed and adjusted. Obstructed.

  As schematically shown in FIG. 3 (b), the shut damper 21 is erected on a first spur gear 22 that is rotatably supported at the lower end portion or below the duct 19. The first spur gear 22 is configured to rotate integrally with the shut damper 21 with a central shaft 22a extending in the vertical direction as a pivot axis. Further, the first spur gear 22 meshes with the damper knob 24 via the second spur gear 23. The damper knob 24 has a substantially disc shape and an end portion (front end portion) facing the second spur gear 23 is configured as a spur gear. The damper knob 24 is pivotally supported so as to be rotatable in the left-right direction. An operation knob portion 24 a is provided at the rear end portion of the damper knob 24. A slip prevention recess 24b is formed on the outer peripheral surface of the operation knob 24a. When the damper knob 24 is rotated, the shut damper 21 rotates in the duct 19 so as to close the second RF register 20 so that it can be opened and closed.

  On the other hand, a rectangular plate-like partition plate 25 for partitioning the inside of the storage body 12 in the front-rear direction is orthogonal to the left and right side walls 12a inside the storage body 12 located on the vehicle rear side of the air inflow hole 16. It is arranged like this. The partition plate 25 divides the inside of the storage body 12 into two storage chambers, a front storage chamber 26 and a rear storage chamber 27. The front storage chamber 26 preferably stores storage items such as beverage cans that have a high need for heat insulation or cold storage, and the rear storage chamber 27 stores storage items that have a low need for heat insulation or cold storage.

  A pair of front and rear support protrusions 28 project from the left and right side walls 12a of the storage body 12 in the longitudinal direction of the vehicle so as to extend in the vertical direction, and the partition plate 25 is detachably supported in the storage body 12. is doing. The vertical length of the partition plate 25 may be set slightly shorter (for example, 5 mm) than the depth of the storage body 12.

Next, the operation of the present embodiment configured as described above will be described.
Now, as shown by the two-dot chain line in FIGS. 1 and 2, when the beverage can 31 is kept warm or cold in the storage body 12, the beverage can 31 is preferably stored in the front storage chamber 26 first. Then, the upper surface opening of the storage body 12 is closed with the lid 15. Subsequently, by rotating the damper knob 24, the second RF register 20 is closed by the shut damper 21 as shown in FIG. Then, the conditioned air flowing in the duct 19 cannot flow out from the second RF register 20 into the vehicle interior, but instead flows into the front storage chamber 26 through the air inflow hole 16. At this time, the inside of the front storage chamber 26 is warmed or cooled by the inflowing conditioned air.

  Here, a slight gap is formed between the upper end edge of the partition plate 25 in the storage body 12 and the lid body 15. For this reason, the conditioned air flows into the front storage chamber 26 and then flows out through the gap into the rear storage chamber 27 to warm or cool the rear storage chamber 27, and then the first RF register 18. And blow out into the passenger compartment. At this time, since the heat retaining function or the cold retaining function due to the continuous circulation of the conditioned air is exhibited inside the storage body 12, the interior of the storage body 12 is warmed or cooled to drink The can 31 is kept warm or cold. In particular, since the inside of the front storage chamber 26 is located closer to the air conditioner than the rear storage chamber 27 and on the upstream side in the flow of conditioned air, the air in a state where the temperature difference from the ambient temperature is large is intense. Inflowing, the thermal insulation or cold insulation effect is higher than that of the rear storage chamber 27. On the other hand, as shown in FIG. 1A, when the shut damper 21 is rotated to open the second RF register 20, the conditioned air flows from the second RF register 20 to the rear end of the duct 19 and then travels from the second RF register 20 to the vehicle. It flows out into the room.

The effects exhibited by the above embodiment will be described below.
-The box main body 11a of the present embodiment includes a storage body 12. A duct 19 extends in contact with the left and right side walls 12 a of the storage body 12, and an air inflow hole 16 for communicating with the inside of the duct 19 is provided. Further, the second RF register 20 is closed by a shut damper 21 so as to be opened and closed. For this reason, when the second RF resistor 20 is closed by the shut damper 21, the conditioned air flowing through the duct 19 is efficiently flowed into the housing 12. Therefore, the inside of the storage body 12 can exhibit a heat insulation or cold insulation function by the inflow of conditioned air.

  In addition, since the duct 19 is provided so as to be in contact with the left and right side walls 12a of the storage body 12 and the air inflow holes 16 are provided in the left and right side walls 12a, as shown in FIG. Air flows in a direction perpendicular to the flow direction in the duct 19 and is guided into the housing 12. For this reason, when the second RF register 20 is opened, the conditioned air in the duct 19 flows out from the air inflow hole 16 into the housing 12 with almost no inflow. Therefore, the conditioned air in the duct 19 can be distributed very smoothly. That is, since the air inflow hole 16 is provided at a position that does not interfere with the flow of conditioned air in the duct 19, the flow of the conditioned air is not hindered.

  The storage body 12 is formed in a bottomed long rectangular box shape, and both the front wall 12b and the left and right side walls 12a are formed of a flat rectangular plate. For this reason, since the storage body 12 of this embodiment is formed in a shape that can make maximum use of the space of the corner portion, the left and right sides of the front wall are formed in a circular arc shape that curves inward. It is easier to increase the storage capacity (volume) than the conventional storage compartment.

  The storage body 12 is provided with an air inflow hole 16 at a front end portion on both sides thereof, and a first RF register 18 is provided at the center lower portion of the rear wall 12c. For this reason, the conditioned air flowing into the front storage chamber 26 flows easily and smoothly from the front to the rear in the storage body 12 and then blows out from the first RF register 18 to the vehicle interior. Therefore, compared with the case where the air inflow hole 16 is provided in the vehicle longitudinal direction center part or the rear end part of the left and right side walls 12a, the flow of the conditioned air is less disturbed. It is easy to spread, and it is easy to smoothly distribute while increasing the distribution speed.

  In particular, since the conditioned air flows in one direction from the front to the rear of the storage body 12, the conditioned air that has flowed into the storage body 12 is difficult to return into the duct 19. For this reason, the flow of conditioned air in the duct 19 is less likely to be disturbed.

  Since the partition plate 25 in the storage body 12 is disposed behind the air inflow hole 16, there is an effect of improving the heat insulation or cold insulation efficiency of the front storage chamber 26. Therefore, only a part of the storage body 12 can be kept warm or cold locally and intensively.

  A plurality of air inflow holes 16 are formed on each side wall 12 a of the storage body 12. Further, the air inflow hole 16 is formed in a long hole shape (long square hole shape) extending in the vertical direction. This shape is a shape in which the opening height in the direction orthogonal to the flow direction is larger than the opening width in the vehicle front-rear direction, which is the flow direction of the conditioned air in the duct 19. For this reason, since the opening width of the air inflow hole 16 is narrow, it is easy to reduce the entire size of the turbulent flow swirling against the flow direction of the conditioned air in the duct 19. Therefore, the flow of conditioned air in the duct 19 is not easily disturbed. Further, even if the total opening area provided through each side wall 12a is the same, the size of the turbulent flow is reduced by providing a plurality of air inflow holes 16 rather than a single large air inflow hole 16. May be able to.

Next, the embodiment will be described more specifically with reference to test examples and comparative examples.

After being lowered, the temperature became stable, and after 1 hour from the start of measurement, the temperature dropped by 11 ° C. relative to the temperature around the console box 11. For this reason, the console box 11 exhibited an excellent cooling function. On the other hand, the temperature in the storage body 12 in Comparative Example 1 gradually increases with the start of measurement because the cooling air did not flow through each duct 19, and after one hour from the start of measurement, the temperature around the console box 11 is increased. It rose 1 ° C.

In Test Example 2, the surface and the temperature of the contents were the same as the temperature around the console box 11, except that the beverage can 31 was stored in the front end (front side of the support protrusion 28) in the storage body 12. Under the same measurement conditions as in No. 1, the temperatures of the front end portion and rear end portion of the container 12 and the surface of the beverage can 31 were measured. Here, each temperature is measured when the second RF register 20 is closed and when the storage body 12 is partitioned by the partition plate 25, the second RF register 20 is opened and the storage body 12 is partitioned and the second RF register 20 is closed. In addition, the case where the inside of the storage body 12 was not partitioned and the case where the second RF register 20 was opened and the interior of the storage body 12 was not partitioned were performed. Furthermore, the gap between the partition plate 25 and the lid body 15 was 5 mm (opening area: 1000 mm ² ). The result is shown in FIG.

  In FIG. 5, the case where the second RF register 20 is closed and the storage body 12 is partitioned by the partition plate 25 is indicated by “A”, and the case where the second RF register 20 is opened and the storage body 12 is partitioned is indicated by “B”. It shows with. Further, the case where the second RF register 20 is closed and the storage body 12 is not partitioned is indicated by “C”, and the case where the second RF register 20 is opened and the storage body 12 is not partitioned is indicated by “D”. In addition, the vertical axis of FIG. 5 shows the temperature difference with respect to the reference, with the temperature around the console box 11 as the reference (t ° C.).

As shown in FIG. 5, the console box 11 was able to lower the temperature of the surface of the beverage can 31 in each case, and was able to exhibit an excellent cold insulation function.
