As described above, a box-type luggage compartment having a mechanism for adjusting the temperature in the luggage compartment is conventionally known. However, a mechanism capable of more preferably raising the temperature of the luggage compartment or the wall constituting the luggage compartment has been conventionally required. For example, a mechanism capable of suitably raising the temperature of the luggage compartment or the wall to the extent that dew condensation does not occur has been conventionally required.

In one feature, the present invention relates to a vehicle box-type luggage compartment. The vehicle box-type luggage compartment includes an in-wall ventilation path formed in the wall that constitutes the luggage compartment, a heater that warms the air, a blower that introduces the air warmed by the heater into the in-wall ventilation passage, and a wall. It has an opening formed in the wall for discharging air from the inner ventilation path into the luggage compartment, and an introduction path for introducing air from the luggage compartment to the heater.

Therefore, the air in the luggage compartment is warmed by the heater, the walls of the luggage compartment are warmed by the warmed air, and then the air is returned to the luggage compartment. The luggage compartment is warmed by warming the walls, and the luggage compartment is also warmed by the air discharged from the walls. By warming the wall, the cold temperature from the outside is first blocked by the wall. Therefore, it is possible to effectively suppress the occurrence of dew condensation on the luggage such as precision machinery and electronic parts in the luggage compartment. Moreover, it is not necessary to provide a heat insulating material on the wall, and the wall can be constructed at low cost. Alternatively, the capacity of the luggage compartment can be increased by making the wall thinner. Alternatively, the luggage compartment can be made lighter by not providing the heat insulating material. This increases the amount of luggage that can be loaded in the luggage compartment.

A hole 4f1 is formed in the horizontal portion 4f3, and the hole 4f1 opens toward the wing ceiling 5a.

As shown in FIG. 8, the hole 5p of the wing ceiling 5a is formed on the inner side 5h1 (see FIG. 7) of the cover 5h. The hole 5p overlaps the hole 4f1 of the rear wall 1b by closing the wing 5, whereby the air in the wing ceiling 5a is introduced into the rear wall 1b. A rubber packing for improving the sealing property is mounted around the holes 5p and 4f1.

As shown in FIG. 8, since the air of the wing side wall 5b is introduced into the rear wall 1b, the hole 4a1 is formed in the rear wall 1b and the hole 5q is formed in the wing side wall 5b. The hole 4a1 is formed in the upper region of the pipe 4a located on the side of the rear wall 1b. The holes 4a1 are opened outward in the vehicle width direction. The hole 5q of the wing side wall 5b is formed on the inner side 5j1 (see FIG. 6) of the cover 5j. The hole 5q overlaps the hole 4a1 of the rear wall 1b by closing the wing 5, whereby the air in the wing side wall 5b is introduced into the rear wall 1b. A rubber packing for improving the sealing property is attached around the holes 5q and 4a1.

As shown in FIG. 8, in order to introduce the air in the tilt 6 into the rear wall 1b, a hole 4a2 is formed in the rear wall 1b, and a hole 6k is formed at the rear end of the tilt 6. The holes 4a2 are formed in the lower region of the pipe 4a located on the side of the rear wall 1b. The holes 4a2 are opened outward in the vehicle width direction. The hole 6k of the tilt 6 is formed on the inner side of the cover 6h, and by closing the tilt 6, it overlaps the hole 4a2 of the rear wall 1b. As a result, the air in the tilt 6 is introduced into the rear wall 1b. A rubber packing for improving the sealing property is mounted around the holes 6k and 4a2.

As shown in FIG. 8, the rear wall 1b is provided with a blower 15 for discharging the air in the rear wall 1b into the luggage compartment 1. The blower 15 has a long shape and is installed in the frame 4, for example, in the upper pipe 4c. The blower 15 sucks in the air in the frame 4 and discharges the air to the luggage compartment 1 through the opening 4c1 formed in the pipe 4c. The opening 4c1 is located, for example, substantially in the center in the vehicle width direction and is long in the vehicle width direction. The blower 15 sucks the air in the wall to form a flow from the front side to the rear side in the wall. Therefore, the air in the wall whose temperature has been adjusted by the temperature regulators 10 and 20 flows from the front wall 1a toward the rear wall 1b. Then, the air in the wall is discharged to the vicinity of the rear wall 1b in the luggage compartment 1 by the discharge force of the blower 15.

As shown in FIG. 9, the luggage compartment floor 2 has, for example, two upper and lower plates 2a and 2b and a reinforcing member 2d installed between the two plates 2a and 2b. An in-wall ventilation passage 2c is formed between the plates 2a and 2b, and the in-wall ventilation passage 2c extends in the front-rear direction of the vehicle. The front opening of the in-wall ventilation passage 2c is covered by a front wall 1a, for example, a lower pipe 3b. The pipe 3b is formed with an opening 3b1 that opens into the ventilation passage 2c in the wall, and the air in the front wall 1a is introduced into the luggage compartment floor 2. As shown in FIG. 8, the rear opening of the in-wall ventilation passage 2c is covered by a rear wall 1b, for example, a lower pipe 4b. The pipe 4b is formed with an opening 4b1 that opens into the ventilation passage 2c in the wall, and the air in the luggage compartment floor 2 is introduced into the rear wall 1b.

The inside of the luggage compartment 1 may be set to a predetermined temperature, for example, 20 to 25 ° C. so that dew condensation does not occur on the luggage stored in the luggage compartment 1. In this case, any one or both of the temperature regulators 10 and 20 are driven, and the temperature regulators 10 and 20 suck in the air in the luggage compartment 1. When the air in the luggage compartment 1 is lower than a predetermined temperature, the temperature regulators 10 and 20 warm the air and discharge it into the luggage compartment 1. At the same time, the temperature regulators 10 and 20 also supply warm air into the walls constituting the luggage compartment 1. The warm air introduced into the wall flows from the front wall 1a toward the rear wall 1b, and flows toward the rear wall 1b through, for example, the luggage compartment ceiling 1d, the side wall 1c, and the luggage compartment floor 2. The warm air that has reached the rear wall 1b is discharged to the luggage compartment 1 through the opening 4c1 shown in FIG. Therefore, warmed air is discharged into the luggage compartment 1 from both the opening 14 of the front wall 1a shown in FIG. 2 and the opening 4c1 of the rear wall 1b shown in FIG.

When the temperature of the luggage compartment 1 is lower than that of the outside air, for example, when the luggage in the luggage compartment 1 is to be refrigerated, the temperature controller 10 is used. The air is cooled by the temperature controller 10, and the cooled air is supplied not only to the inside of the luggage compartment 1 but also to the inside of the wall constituting the luggage compartment 1. Cooled air is introduced into the luggage compartment 1 from both the opening 14 of the front wall 1a shown in FIG. 2 and the opening 4c1 of the rear wall 1b shown in FIG. Cooled air flows through the wall from the front wall 1a toward the rear wall 1b, for example, through the side wall 1c, the luggage compartment ceiling 1d, and the luggage compartment floor 2, and toward the rear wall 1b.

The temperature controller 20 can be used to avoid the accumulation of snow on the luggage compartment ceiling 1d, for example, when it is predicted that it will snow when the vehicle is stopped. The temperature controller 20 can warm the air by using the liquid fuel even when the engine of the vehicle 40 is not driven. A switch for turning on / off the temperature controller 20 is provided on the front wall 1a or the driver's cab 40b. The temperature controller 20 is operated by the ON / OFF switch to set the luggage compartment ceiling 1d to a predetermined temperature, for example, 6 to 10 ° C. As a result, the snow that has fallen on the luggage compartment ceiling 1d receives heat from the luggage compartment ceiling 1d and melts. As a result, it is possible to prevent snow from accumulating on the luggage compartment ceiling 1d.

As described above, the vehicle box-type luggage compartment 1 has in-wall ventilation passages (pipes 3a to 3c, 4a to 4c, in-wall ventilation passages 2c, 5f, 6f) formed in the wall constituting the luggage compartment 1. Has. Further, the luggage compartment 1 includes heaters (temperature regulators 10 and 20) that warm the air, blowers 13 and 15 that introduce the air warmed by the heater into the ventilation passage inside the wall, and the ventilation passage inside the wall into the luggage compartment 1. It has an opening 4c1 formed in the wall for discharging air, and an introduction path (openings 14, 24) for introducing air from the luggage compartment 1 to the heater.

Therefore, the air in the luggage compartment 1 is warmed by the heaters (temperature regulators 10 and 20), the wall of the luggage compartment 1 is warmed by the warmed air, and then the air is returned into the luggage compartment 1. The inside of the luggage compartment 1 is warmed by warming the wall, and the inside of the luggage compartment 1 is also warmed by the air discharged from the wall. By warming the wall, the cold temperature from the outside is first blocked by the wall. Therefore, it is possible to effectively suppress the occurrence of dew condensation on the luggage such as precision machinery and electronic parts in the luggage compartment 1. Moreover, it is not necessary to provide a heat insulating material on the wall, and the wall can be constructed at low cost. Alternatively, the capacity in the luggage compartment 1 can be increased by making the wall thinner. Alternatively, the luggage compartment 1 can be made lighter by not providing the heat insulating material. As a result, the amount of luggage that can be loaded in the luggage compartment 1 increases.

As shown in FIGS. 3 to 5, the luggage compartment 1 includes a luggage compartment ceiling 1d having an in-wall ventilation passage 5f, a temperature sensor that directly or indirectly measures the temperature of air flowing through the in-wall ventilation passage 5f, and a temperature. It has temperature regulators 10 and 20 that control the heater based on the signal from the sensor to adjust the temperature of the air in the ventilation passage 5f in the wall. The temperature regulators 10 and 20 adjust the temperature of the ventilation passage 5f in the wall so as to prevent snow from accumulating on the ceiling 1d of the luggage compartment. For example, the temperature regulators 10 and 20 adjust the temperature of the ventilation passage of the luggage compartment ceiling 1d to 6 to 10 ° C.

Therefore, it is possible to prevent snow from accumulating on the luggage compartment ceiling 1d. For example, when it is predicted that it will snow while the vehicle is stopped, the luggage compartment ceiling 1d is controlled to be kept at a predetermined temperature or higher, for example, 6 ° C. or higher. As a result, the snow that has fallen on the luggage compartment ceiling 1d is melted by the heat from the luggage compartment ceiling 1d. As a result, it is possible to prevent snow from accumulating on the luggage compartment ceiling 1d. When melting the snow that has accumulated on the luggage compartment ceiling 1d, it is necessary to set the temperature higher than that. Therefore, by operating this device before it snows, it is possible to avoid snow accumulation on the luggage compartment ceiling 1d at a relatively low temperature.

While traveling, the snow accumulated on the luggage compartment ceiling 1d can be blown off by the traveling wind. However, in order to prevent dew condensation from forming on the luggage in the luggage compartment 1, the temperature inside the luggage compartment 1 is set to a predetermined temperature by removing the snow on the ceiling 1d of the luggage compartment before carrying the luggage into the luggage compartment 1. There is a need. Therefore, avoiding snow from accumulating on the luggage compartment ceiling 1d while the vehicle is stopped can improve the convenience of the luggage compartment 1.

As shown in FIGS. 2 and 3, the luggage compartment 1 has an introduction path (openings 14, 24) connecting the luggage compartment 1 and the heater in order to introduce air from the luggage compartment 1 into the heaters (temperature regulators 10 and 20). Has. Further, the luggage compartment 1 has a first exhaust passage (openings 14, 24) connecting the heater and the luggage compartment 1 in order to discharge the air warmed by the heater to the luggage compartment 1, and a wall of the air warmed by the heater. Second exhaust passages (ducts 11, 12, 21, 22) that connect the heater and the internal ventilation passages for discharge to the internal ventilation passages (pipes 3a to 3c, 4a to 4c, internal ventilation passages 2c, 5f, 6f). ).

Therefore, a part of the warm air discharged from the heater is discharged into the luggage compartment 1 through the wall. The remaining air is discharged directly to the luggage compartment 1. Therefore, the inside of the luggage compartment 1 can be warmed more effectively. Moreover, the outside cold air can be effectively blocked by the wall.

As shown in FIG. 8, the blower 15 is provided in the ventilation passage (pipe 4c) in the wall. The air in the ventilation passage in the wall is discharged to the luggage compartment 1 through the opening 4c1 by the blower 15. Therefore, the warm air discharged from the heater is sucked into the wall ventilation passages (pipes 3a to 3c, 4a to 4c, wall ventilation passages 2c, 5f, 6f) by the blower 15, and is sucked into the luggage compartment through the opening 4c1 by the blower 15. It is discharged into 1. Therefore, the blower 15 uses both the force of sucking air and the force of discharging air to flow air into the luggage compartment 1 and the wall.

As shown in FIG. 2, the luggage compartment 1 includes a luggage compartment floor 2, a front wall 1a standing at the front end of the luggage compartment floor 2, a rear wall 1b standing up at the rear end of the luggage compartment floor 2, and a front wall 1a. It has a side wall 1c extending between the rear walls 1b. At least the front wall 1a and the side wall 1c have in-wall ventilation passages (pipes 3a to 3c, in-wall ventilation passages 5f, 6f). Heaters (temperature regulators 10, 20) are mounted on the front wall 1a. The opening 4c1 is provided on the rear wall 1b. The blower 15 is provided in the in-wall ventilation path (pipe 4c) in the vicinity of the opening 4c1. The air warmed by the heater is introduced into the in-wall ventilation passages (pipes 3a to 3c) of the front wall 1a, and flows from the in-wall ventilation passage of the front wall 1a to the in-wall ventilation passage of the side wall 1c, and passes through the opening 4c1. After that, it is discharged from the rear wall 1b into the luggage compartment 1.

Therefore, the air warmed by the heater warms the front wall 1a, the side wall 1c is warmed, and the warmed air flows toward the rear wall 1b. Then, the inside of the luggage compartment 1 is warmed by the air discharged from the vicinity of the rear wall 1b. Therefore, the front region of the luggage compartment 1 is warmed through the front wall 1a and the like, and the rear region is directly warmed by discharging warm air. Therefore, the entire inside of the luggage compartment 1 can be efficiently warmed.

The luggage compartment 1 is composed of a temperature sensor that directly or indirectly measures the temperature of air flowing through the in-wall ventilation passages (pipes 3a to 3c, 4a to 4c, in-wall ventilation passages 2c, 5f, 6f) and a temperature sensor. It has temperature regulators 10 and 20 that control the heater based on the signal of the above to adjust the temperature of the air in the air passage in the wall. The temperature regulators 10 and 20 set the temperature of the ventilation passage in the wall to 20 to 25 ° C. As a result, the occurrence of dew condensation on the luggage in the luggage compartment 1 can be reliably suppressed.

The luggage compartment 1 may have a form shown in FIGS. 10 and 11 instead of the form shown in FIGS. 1 to 9. The luggage compartment 1 shown in FIG. 10 has a temperature regulator 53 and a duct (exhaust passage) 50 in place of the temperature regulators 10 and 20 and ducts 11, 12, 21 and 22 shown in FIG. The luggage compartment 1 shown in FIG. 11 has a wing 52 in place of the wing 5 shown in FIG.

As shown in FIG. 10, the temperature regulator 53 is, for example, a combustion type heater like the temperature regulator 20 described above, and warms the air with liquid fuel or the like. The temperature controller 53 sucks the air in the luggage compartment 1 from the opening 14 (see FIG. 2) formed in the front wall 1a or the duct that opens in the luggage compartment 1. One end of the duct 50 is connected to the temperature controller 53, and the other end of the duct 50 is connected to the pipe 3c. A blower 51 is provided in the duct 50. The blower 51 is, for example, a blower, and sends the air discharged from the temperature controller 53 into the frame 3.

As shown in FIG. 10, the air discharged from the temperature controller 53 to the frame 3 is supplied only into the in-wall ventilation passage of the pipe 3c. That is, the in-wall ventilation passage of the pipe 3c is inaccessible from the in-wall ventilation passage of the other pipes 3a, 3b, 3d, 3e. The air warmed by the temperature controller 53 is sent to the ventilation passage in the wall of the pipe 3c via the duct 50, and is supplied from the pipe 3c to the luggage compartment ceiling 1d via the connecting duct 3f.

As shown in FIG. 11, the luggage compartment ceiling 1d includes a wing ceiling 52a which is a part of the wing 52. The wing 52 has a wing ceiling 52a and a wing side wall 52b. The wing ceiling 52a is rotatably connected to the center pillar 9. The wing ceiling 52a has a luggage compartment wall 52c, a luggage compartment outer wall 52d, and ribs 52e that stand up between the luggage compartment outer wall 52c and the luggage compartment outer wall 52d. The rib 52e extends in the front-rear direction of the vehicle. Therefore, the wing ceiling 52a is formed with an in-wall ventilation passage 52f extending in the front-rear direction of the vehicle. The wing ceiling 52a has a plurality of tubular portions 52g provided with an in-wall ventilation passage 52f, and the tubular portions 52g are arranged side by side to form a plate shape.

As shown in FIG. 11, the wing side wall 52b extends from an end of the wing ceiling 52a located outside in the vehicle width direction so as to be substantially orthogonal to the wing ceiling 52a. The wing side wall 52b has a single plate shape and constitutes the upper part of the side wall 1c.

The wing ceiling 52a shown in FIG. 11 is formed in the same manner as the wing ceiling 5a shown in FIG. That is, by closing the wing 52, the air in the front wall 1a is introduced into the wing ceiling 52a via the connecting duct 3f and flows to the rear of the vehicle through the ventilation passage 52f in the wall. The air in the wing ceiling 52a is introduced into the rear wall 1b via the connecting duct 4f of the rear wall 1b shown in FIG. Then, it is discharged into the luggage compartment 1 through the opening 4c1 formed in the rear wall 1b.

In the luggage compartment 1 shown in FIGS. 10 and 11, the air is warmed by the temperature regulator 53, and the air warmed to a predetermined temperature is introduced into the luggage compartment ceiling 1d. No temperature-controlled air is introduced into the rest of the wall, and strictly speaking, no temperature-controlled air is introduced except for the upper part of the front wall 1a, the upper part of the rear wall 1b, and the luggage compartment ceiling 1d. Then, the air flowing in the vehicle front-rear direction in the wall is discharged to the luggage compartment 1 from the rear wall 1b or from the vicinity of the rear wall 1b.

When avoiding the accumulation of snow on the luggage compartment ceiling 1d, for example, when it is predicted that it will snow when the vehicle is stopped, the temperature controller 53 shown in FIG. 10 can be used. The temperature controller 53 can warm the air by using the liquid fuel even when the engine of the vehicle 40 is not driven. The temperature regulator 53 is set to a temperature that can be melted by the temperature of the luggage compartment ceiling 1d when snow is attached to the luggage compartment ceiling 1d, for example, 6 to 10 ° C. As a result, the snow that has fallen on the luggage compartment ceiling 1d receives heat from the luggage compartment ceiling 1d and melts.

Alternatively, the opening may be formed in the vicinity of the rear wall 1b of the side wall 1c, the vicinity of the rear wall 1b of the luggage compartment ceiling 1d, or the vicinity of the rear wall 1b of the luggage compartment floor 2. Then, a blower may be provided in the ventilation passage in the wall in the vicinity of the opening.

As shown in FIG. 9, the luggage compartment floor 2 has an in-wall ventilation passage 2c formed between the two plates 2a and 2b. Instead of this, the luggage compartment floor 2 may have a frame provided with a plurality of pipes as in the front wall 1a shown in FIG. 3 or the rear wall 1b shown in FIG. The frame may be formed with holes for introducing temperature-controlled air from the front wall 1a and holes for allowing air to flow to the rear wall 1b.

As described above, the temperature sensor is provided, for example, on the lower side of the front wall 1a. Instead of this, the temperature sensor may be provided in the wall or in the luggage compartment ceiling 1d.

The temperature of the luggage compartment ceiling 1d is set to 6 to 10 ° C. as the temperature at which snow does not accumulate. Instead of this, the temperature of the luggage compartment ceiling 1d may be set to another temperature, for example, 5 ° C. or higher, 8 ° C. or lower, 15 ° C. or lower, a combination thereof, or the like.
