However, in the prior art disclosed in Patent Document 1, there is a problem that only a part of the passenger's body can be heated because the passenger receives the heat of the heat storage body directly by contacting the heat storage body. .
Moreover, in the prior art disclosed in Patent Document 2, since the heat accumulator is disposed outside the passenger compartment, the heat of the heat accumulator is taken away when passing through the duct, and the heat of the heat accumulator is efficiently obtained. There is a problem that it cannot be used for air conditioning of the passenger compartment.

  The present invention has been made in view of the above problems, and an object of the present invention is to efficiently use the heat of the heat accumulator by heat transfer based on heat dissipation or heat absorption of the heat accumulator and in a driver's seat and a passenger seat in the vehicle interior.

According to the present invention, the heat storage body of the heat storage body unit disposed between the driver's seat and the passenger seat warms or cools the body of at least one of the driver seat and the passenger seat.
Since the heat storage unit is located near the driver seat and the passenger seat, at least one passenger of the driver seat and the passenger seat is likely to receive heat dissipation or heat absorption of the heat storage body.
When the heat storage body dissipates heat, at least one of the driver seat and the passenger seat is warmed by heat transfer due to radiation from the heat storage body to the passenger.
Further, when the heat storage body absorbs heat, heat is absorbed by the heat storage body by the heat transfer from at least one passenger of the driver seat and the passenger seat to the heat storage body, and the passenger is cooled.
As a result, according to the present invention, the heat of the heat storage body can be efficiently used to warm or cool the body of at least one of the driver seat and the passenger seat in the passenger compartment over a wide range.

  Moreover, this invention may be arrange | positioned in the said thermal storage body case in the said vehicle-mounted thermal storage apparatus in the said thermal storage body case at intervals between the said thermal storage body at least the side surface.

In this case, since an interval is formed between the heat storage body and the side surface of the heat storage body case, the heat of the heat storage body is hardly transmitted to the heat storage body case, and the temperature of the side surface of the heat storage body case does not increase excessively.
As a result, it is not necessary to use a heat insulating material for the heat storage case, or a material having a low heat insulating performance can be used.
Air in the space provided between the heat storage body and the heat storage case can be used as a heat transfer medium, and heat transfer by air convection is possible.

  In the on-vehicle heat storage device according to the present invention, the through hole may be provided toward at least one of a driver seat and a passenger seat.

Moreover, this invention WHEREIN: In said vehicle-mounted heat storage apparatus, the inner surface of the said opening / closing body may have a high heat | fever reflection part.
Note that the high heat reflecting portion means a portion having a low heat loss and a high heat reflectivity during heat reflection, and includes, for example, a mirror-finished surface or a surface formed of a material having a high reflectivity.

In this case, the high heat reflecting portion provided on the inner surface of the opening / closing body has a high heat reflectance, and heat loss of radiation to the opening / closing body can be suppressed.
When the open / close body is open, the heat transfer from the heat storage body to the outside of the heat storage body case or the heat transfer from the outside of the heat storage body case to the heat storage body is caused by the reflection of heat by the high heat reflecting part, As compared with the case where the high heat reflection portion is not formed, the increase is caused.

In this case, even if the passenger touches the outer surface of the heat storage case, the outer surface of the heat storage case is covered with a low heat transfer material having a lower heat transfer property than the heat storage case. I don't feel the low temperature.
In addition, the low heat transfer performance of the low heat transfer material means that the passenger does not feel excessively hot or excessively cold even if the vehicle passenger contacts the outer surface of the heat storage case. Means heat transfer performance.

  Moreover, this invention may be formed in the said vehicle-mounted heat storage apparatus by the uneven surface which has an unevenness | corrugation in the outer surface of the said thermal storage body.

In this case, since the outer surface of the heat storage body is formed on an uneven surface having unevenness, the surface area on the outer surface of the heat storage body is increased as compared to the case of an outer surface with a flat surface without unevenness.

In FIG. 3, for convenience of explanation, the driver HA seated on the driver seat 14 and the passenger seat passenger HB seated on the passenger seat 15 are illustrated by virtual lines.
The driver HA and the passenger on the front passenger seat HB correspond to passengers on the vehicle 10.

In this embodiment, since the vehicle 10 is a right-hand drive vehicle, the driver's seat 12 is a space in which the steering wheel 19 on the right side in the traveling direction partitioned by the center console 20 in the vehicle compartment 11 is disposed in the vehicle width direction. And in the vehicle front-back direction, it is the space set between the instrument panel 18 and the backrest part of the driver's seat 14.
On the other hand, the front passenger seat 13 is a space on the left side in the traveling direction defined by the center console 20 in the vehicle compartment 11 in the vehicle width direction, and in front of the instrument panel 18 and the instrument panel 8 in the vehicle front-rear direction. This is a space set between the partition wall and the backrest portion of the passenger seat 15.
Both the driver's seat 12 and the passenger seat 13 are spaces set between the floor and the ceiling in the vertical direction.
In the vicinity of the floor surface of the driver's seat 12 and the passenger seat 13, a foot space in which a passenger's legs are placed is formed.
The foot space is lower than the seating surfaces of the seats 14 and 15 of the driver seat 12 and the passenger seat 13, and is a space formed between the partition wall and the seats 14 and 15 below the instrument panel 8.
When the vehicle is a left-hand drive vehicle, the driver seat and the passenger seat are opposite in the vehicle width direction.

The heat storage apparatus of 1st Embodiment has the thermal storage body unit 30 installed in the cavity part 22 of the center console 20, as shown in FIGS.
In this embodiment, the heat storage unit 30 is installed between the foot space of the driver's seat 12 and the foot space of the passenger seat 13.
As shown in FIGS. 4 and 5, the heat storage unit 30 includes a heat storage body 31 that enables heat dissipation or heat absorption and a heat storage body case 34 that covers the heat storage body 31.
The heat storage body 31 includes a heat storage material storage tank 33 that stores the heat storage material 32 and a heat storage material 32 stored in the heat storage material storage tank 33.
The heat storage material storage tank 33 is a container formed of a metal having high thermal conductivity, for example, an aluminum-based metal material.
As shown in FIG. 4, since the uneven surface 33A is formed on the outer surface of the heat storage material storage tank 33, the surface area of the outer surface of the heat storage material storage tank 33 is compared with the case where the uneven surface 33A is not formed. Will increase.
By increasing the surface area of the outer surface of the heat storage material storage tank 33, the heat dissipation performance or heat absorption performance (heat exchange performance) of the heat storage body 31 is enhanced.

The heat storage material 32 stored in the heat storage material storage tank 33 is water. For example, when the inside of the passenger compartment 11 is cold, the heat storage material 32 is kept in a high temperature state (for example, hot water state) as a heat radiation source for heating. The heat is stored by the heat storage body 31.
Conversely, when the interior of the passenger compartment 11 becomes hot, the heat storage material 32 is placed in a low temperature state (for example, in an ice state) so that heat is absorbed by the heat storage body 31 as a heat absorption source for cooling.
The heat storage material 32 in the heat storage material storage tank 33 can be used as a heat radiation source by storing heat in the heat storage body 31 by heating by energizing a Peltier element (not shown). This is possible by taking heat away from the heat storage body 31 by heat absorption by energization of the element.
When a Peltier element is used to make the heat storage material a heat radiation source or a heat absorption source, a part of external power is supplied to the Peltier element during charging of a battery (not shown) mounted on the vehicle 10 to store heat. It is preferable to increase or decrease the temperature of the material 32.
Alternatively, by directly supplying hot water or ice into the heat storage material storage tank 33, the heat storage material 32 in the heat storage material storage tank 33 may be used as a heat radiation source or a heat absorption source.

Next, the heat storage body case 34 will be described.
The heat storage case 34 is formed in a box shape from an aluminum-based metal material having a high thermal conductivity.
As shown in FIGS. 4 and 5, the heat storage case 34 includes a pair of left and right side plate portions 35, a front plate portion 36, a rear plate portion 37, a top plate portion 38, and a bottom plate portion 39.
Of the inner surface of the heat storage body case 34, the inner surfaces of the side plate portion 35 excluding the bottom plate portion 39, the front plate portion 36, the rear plate portion 37, and the top plate portion 38 are formed by uneven surfaces 34A having unevenness. Yes.
The bottom plate portion 39 of the heat storage body case 34 is formed from an inclined surface that is inclined from the outside toward the center, and the bottom plate portion 39 of the heat storage body case 34 is fixed to the floor surface of the vehicle 10.
The inner surface of the bottom plate portion 39 is formed by a mirror-finished surface 34B, and the mirror-finished surface 34B reflects the heat of radiation.

A conduction path 40 is formed at the bottom of the bottom plate portion 39.
The bottom plate portion 39 is provided to collect moisture condensed on the surface of the heat storage body 31 and the inner surface of the heat storage body case 34 (hereinafter referred to as “condensation water”) in the conduction path 40.
The conduction path 40 is connected to a bottom plate portion 39 that forms the bottom surface of the heat storage body case 34 and communicates with the inside of the heat storage body case 34 and the outside of the vehicle. The conduction path 40 is provided with an open / close valve (not shown). Yes.
When a predetermined amount of condensed water accumulates in the conduction path 40, the open / close valve is opened and the condensed water is discharged outside the vehicle.

A housing space for housing the heat storage body 31 is formed in the heat storage body case 34.
The size of the housing space is set such that a space S is formed between the outer surface of the heat storage body 31 and the inner surface of the heat storage body case 34 in a state where the heat storage body 31 is housed.
Therefore, the heat storage body 31 is disposed in the heat storage body case 34 with a space between the heat storage body case 34 and the side plate portion 35 that forms at least the side surface.
Since the heat storage body 31 is housed in the housing space of the heat storage body case 34, the driver HA and the passenger seat passenger HB do not come into contact with the heat storage body 31.

Although not shown, the heat storage body case 34 is a support member that holds the heat storage body 31 in the heat storage body case 34 so as to form a space S between the outer surface of the heat storage body 31 and the inner surface of the heat storage body case 34. I have.
A plurality of slit holes 41 and 42 as through holes are formed in the side plate portion 35 on the driver seat side facing the driver seat 12 and the side plate portion 35 on the passenger seat side facing the passenger seat 13 in the heat storage body case 34. Yes.
A slit hole 43 is also formed in the top plate portion 38 of the heat storage case 34.
The side plate 35 is formed with three slit holes 41 and 42 in the vertical direction and four in the vehicle front-rear direction, and two slit holes 43 in the top plate portion are formed in the vehicle width direction and four in the vehicle front-rear direction. Yes.
The slit hole 41 is provided toward the driver seat 12, and the slit hole 42 is provided toward the passenger seat.
These slit holes 41 to 43 have a substantially rectangular shape and communicate the space S with the outside of the heat storage case 34.
The slit holes 41 to 43 are through holes for performing heat radiation to the outside of the heat storage body case 34 of the heat storage body 31 or heat absorption from the outside of the heat storage body case 34 to the heat storage body 31.

The heat storage case 34 includes shutters 44 to 46 as opening / closing bodies that open and close the slit holes 41 to 43.
The side shutter 44 that opens and closes the slit hole 41 of the driver side plate 35 opens and closes the slit hole 41 by rotating about a fulcrum shaft 47 provided at the upper part of the slit hole 41.
The side shutter 44 is manually opened and closed, and the degree of opening and closing of the slit hole 41 by the side shutter 44 can be freely adjusted.
In a state where the side shutter 44 is rotated outward, the side shutter 44 is in an inclined state, and a gap is formed between the slit hole 41 and the side shutter 44, so that the outside of the space S and the heat storage case 34 is Communicate.
When the side shutter 44 is in a vertical state along the outer surface of the heat storage case 34, the gap is closed between the slit hole 41 and the side shutter 44, and the slit hole 41 is closed by the side shutter 44. .
In the state where the side shutter 44 opens the slit hole 41, the side shutter 44 is inclined, so that even if a foreign object falls from above, the side shutter 44 is guided away from the heat storage case 34. The side shutter 44 closes the slit hole 41. For this reason, it is difficult for foreign matter to enter the slit hole 41.

The side shutter 45 of the slit hole 42 in the side plate portion 35 on the passenger seat side has basically the same configuration as the side shutter 44 that opens and closes the slit hole 41 in the side plate portion 35 on the driver seat side.
The side shutter 45 on the passenger seat side is provided symmetrically with the slit hole 41 on the driver seat side in the vehicle width direction, and opens and closes with the fulcrum shaft 48 as a fulcrum.
The upper shutter 46 of the slit hole 43 provided in the top plate portion 38 rotates with a fulcrum shaft 49 provided near the center of the top plate portion 38 as a fulcrum.
When the upper shutter 46 rotates, a gap is generated between the outer end of the upper shutter 46 and the outer edge of the slit hole 43, and the slit hole 43, the space S, and the outside of the heat storage case 34 communicate with each other.

The amount of heat released from the heat storage body 31 through the slit holes 41 to 43 to the outside of the heat storage body case 34 or the amount of heat absorbed from the outside of the heat storage body case 34 to the heat storage body 31 is determined by the side shutters 44 and 42 and the upper shutter 46. It is controlled according to the opening / closing degree of the slit holes 41 to 43.
The side shutter 44 that opens and closes the slit hole 41 on the driver's seat side, the side shutter 45 and the upper shutter 46 of the slit hole 42 on the passenger seat side have a mechanism for opening and closing individually or collectively. Yes.
For example, only the side shutter 44 on the driver's seat side can be opened and the other shutters 45 and 46 can be closed, or the shutters 44 to 46 can be opened simultaneously.

The inner surface of the heat storage case 34 is formed by an uneven surface 34 </ b> A except for the inner surface of the bottom plate portion 39, but the uneven surface 34 </ b> A can absorb heat due to heat dissipation of the heat storage body 31 or heat dissipation due to heat absorption of the heat storage body 31. Surface.
On the other hand, the inner surfaces of the shutters 44 to 46 are formed of the same aluminum metal material, but mirror-finished surfaces 44 </ b> A to 46 </ b> A are formed as high heat reflecting portions having excellent heat reflectivity.
For this reason, for example, when the heat radiated from the heat accumulator 31 hits the mirror-finished surfaces 44A to 46A of the shutters 44 to 46, the heat is reflected by the mirror-finished surfaces 44A to 46A of the shutters 44 to 46, respectively. Little heat loss due to 44 to 46 occurs.
In a state where each shutter 44 to 46 opens the corresponding slit hole 41 to 43, heat due to radiation of the heat storage body 31 is reflected on the inner surface of each shutter 44 to 46, and a part of the reflected heat is stored in the heat storage body case 34. Radiated to the outside.
For this reason, the heat radiated to the outside of the heat accumulator case 34 due to the radiation from the heat accumulator 31 is larger than that when the mirror-finished surfaces 44A to 46A are not formed on the shutters 44 to 46, respectively.
Note that the high heat reflecting portion means a portion having low heat loss and high heat reflectivity during heat reflection, and includes, for example, mirror-finished surfaces 44A to 46A and surfaces formed of a material having high reflectivity. .

The outer surface of the heat storage case 34 is coated with a low heat transfer material 50, which is a material having a lower heat transfer performance than the heat storage case 34, and the low heat transfer material 50 of this embodiment is a resin.
The low heat transfer performance of the low heat transfer material 50 is, for example, when the temperature of the heat storage material 32 is near the boiling point or the melting point, even if the rider contacts the outer surface of the heat storage case 34, It means heat transfer performance that does not feel excessively hot or excessively cold.
Therefore, even if a passenger contacts the outer surface of the heat storage body case 34 containing the heat storage body 31 that radiates or absorbs heat, the passenger does not feel excessive heat or excessive coldness.
In this embodiment, the low heat transfer material 50 is also coated on the outer surfaces of the shutters 44 to 46.
In addition, as the low heat transfer material 50, in addition to the resin, a heat-resistant foaming material such as urethane or a fiber-based material may be used.

As described above, the heat storage body case 34 that accommodates the heat storage body 31 has a certain heat insulating function and a heat radiation function and a heat absorption function for the surroundings.
In other words, when the heat storage body 31 dissipates heat, the heat storage body case 34 keeps the heat of the heat storage body 31 in the heat storage body case 34 and enables heat received from the heat storage body 31 to be dissipated to the surroundings. Yes.
Further, when the heat storage body 31 absorbs heat, the heat storage body case 34 prevents heat absorption from the periphery of the heat storage body 31 and can absorb heat from the periphery of the heat storage body case 34.

Next, the operation of the in-vehicle heat storage device according to the first embodiment will be described.
First, in the case of heating in which heat is stored in the heat storage material 32 and the passenger is warmed by heat dissipation of the heat storage body 31, and in the case of cooling in which the heat storage material 32 is heat released and the passenger is cooled by heat absorption of the heat storage body 31. Each will be described. Warm up

A case of heating in which a passenger is warmed by heat radiation of the heat storage body 31 in a low temperature environment such as a cold season will be described.
Before the driver who is a passenger gets on, the heat storage material 32 stores heat in advance.
When heat is stored in the heat storage material 32 using a Peltier element, the heat stored in the heat storage material 32 is radiated from the Peltier element by energizing a part of the external power to the Peltier element when the battery mounted on the vehicle 10 is charged. Save it.
Moreover, when not using a Peltier device, you may make it enclose the thermal storage material 32 which heat-stored previously in the thermal storage material storage tank 33, for example.

The heat storage body 31 including the heat storage material 32 that stores heat radiates heat inside the heat storage case 34 as a heat radiation source.
In the heat dissipation of the heat storage body 31, heat transfer is performed by radiation, and the heat of radiation reaches the uneven surface 34 </ b> A of the heat storage body case 34.
Since heat is transferred to the heat storage case 34 by radiation to the uneven surface 34A, heat is stored in the heat storage case 34.
In addition, the heat of radiation of the heat storage body 31 which hits the corresponding mirror-finished surfaces 44A to 46A of the shutters 44 to 46 is reflected.
Further, in the heat radiation of the heat storage body 31, the heat of the heat storage body 31 is transferred to the heat storage body case 34 by heat exchange between the heat storage body 31 and the air in the space S and heat exchange between the air in the space S and the heat storage body case 34. Is transmitted.
Further, in the heat dissipation of the heat storage body 31, natural convection occurs in the space between the heat storage body 31 and the heat storage body case 34.

As shown in FIG. 6, in the state where the shutters 44 to 46 open the corresponding slit holes 41 to 43, heat transfer from the heat storage body 31 to the outside occurs through the slit holes 41 to 43.
The heat transfer through the slit holes 41 to 43 includes heat transfer due to radiation from the surface of the heat storage body 31 (schematically illustrated by dotted arrows in FIG. 6) and heat generated by natural convection around the heat storage unit 30. By movement (schematically illustrated by white arrows in FIG. 6).
When a passenger exists, in the heat transfer by radiation from the surface of the heat storage body 31, the passenger or the vicinity of the passenger becomes a radiation destination.
Since the heat storage case 34 is installed in the center console 20, the heat of radiation through the slit holes 41 to 43 is likely to hit the passenger's legs, and the passenger who has received heat from the radiation on the legs can be placed on the legs. I feel the warmth.

By the way, the air in the heat storage body case 34 is in a state of higher temperature than the temperature of the air outside the heat storage body case 34 due to heat exchange with the heat storage body 31.
In a state where the slit holes 41 to 43 are opened, natural convection is generated by the high-temperature air in the heat storage body case 34 and the low-temperature air outside the heat storage body case 34.
The hot air in the heat accumulator case 34 flows out from the slit holes 41 to 43 due to the occurrence of natural convection, and the hot air in the heat accumulator case 34 that flows out is near the floor surface of the driver seat 12 or the passenger seat 13 on the side where the air flows out. As you warm up.
The passenger can feel the warmth by receiving heat from the air that warms the vicinity of the floor surface of the driver's seat 12 and the passenger seat 13.

By adjusting the opening degree of each shutter 44 to 46, the amount of heat released to the outside of the heat accumulator case 34 due to radiation and convection through the slit holes 41 to 43 is controlled.
The shutters 44 to 46 are operated by a passenger, but the side shutter 44 on the driver seat side, the side shutter 45 on the passenger seat side, and the upper shutter 46 are individually opened and closed.
In the state where the shutters 44 to 46 open the slit holes 41 to 43, the heat transmitted to the heat storage body case 34 is radiated through the outer surface of the heat storage body case 34.
Since the outer surface of the heat accumulator case 34 is coated with the low heat transfer material 50 having a low heat transfer performance, heat radiation from the surface of the heat accumulator case 34 is slow.
Although slow heat dissipation from the outer surface of the heat storage body case 34 (schematically illustrated by solid line arrows in FIG. 6) is performed, the effect of warming the occupant is small compared to heat dissipation through the slit holes 41 to 43.
Thus, the heat radiation of the heat storage body 31 can warm the passenger mainly based on heat transfer by radiation and heat transfer by air convection.

On the other hand, in a state where the shutters 44 to 46 close the corresponding slit holes 41 to 43, the heat transmitted to the heat storage body case 34 is radiated through the outer surface of the heat storage body case 34.
Although slow heat release from the outer surface of the heat storage body case 34 to the outside occurs, most of the heat of the heat storage body 31 remains in the heat storage body case 34.

Next, the case where a passenger is cooled by heat absorption of the heat storage body 31 in a high temperature environment such as summer will be described.
Before the driver who is a passenger gets on the board, the heat of the heat storage material 32 is taken in advance, and the heat storage material 32 is made to function as a heat absorption source.
When heat is taken from the heat storage material 32 using the Peltier element, the heat of the heat storage material 32 is absorbed into the low temperature part of the Peltier element by energizing the Peltier element when the battery mounted on the vehicle 10 is charged.
In this case, specifically, heat is removed from the heat storage material 32 until the water as the heat storage material 32 is frozen.

The heat storage body 31 including the ice storage heat storage material 32 absorbs ambient heat inside the heat storage body case 34.
In the heat storage body 31 as a heat absorption source, heat transfer occurs by radiation from the heat storage body case 34 that is higher in temperature than the heat storage body 31 to the heat storage body 31, and the heat of this radiation is absorbed by the heat storage body 31.
That is, heat transfer by radiation of the heat storage body case 34 to the heat storage body 31 is performed.
Further, in the heat absorption of the heat storage body 31, heat of the heat storage body case 34 is transmitted to the heat storage body 31 by heat exchange between the air in the space S and the heat storage body 31 and heat exchange between the air in the space S and the heat storage body case 34. Is done.
Furthermore, in the heat absorption of the heat storage body 31, natural convection occurs in the space between the heat storage body 31 and the heat storage body case 34.

When the shutters 44 to 46 open the corresponding slit holes 41 to 43, heat transfer from the outside to the heat storage body 31 occurs through the slit holes 41 to 43.
The heat transfer through the slit holes 41 to 43 due to the heat absorption of the heat storage body 31 is the heat transfer due to the radiation from the surface of the high temperature element that is higher in temperature than the heat storage body 31 and the heat generated by the natural convection around the heat storage body unit 30. It is a move.
When the occupant is present, the occupant becomes a high-temperature element, and thus heat transfer from the surface of the occupant to the heat storage body 31 occurs.
Further, heat transfer to the heat accumulator 31 also occurs for high-temperature elements such as indoor inner walls near the passenger.
Since the heat storage body case 34 is installed in the center console 20, the heat of the passenger's legs or the vicinity of the legs is absorbed by the heat storage body 31 by radiation through the slit holes 41 to 43.
The passenger feels the coldness near the legs as heat is taken away from the legs or the vicinity of the legs.

By the way, the air in the heat storage body case 34 is in a state of lower temperature than the temperature of the air outside the heat storage body case 34 by heat exchange with the heat storage body 31.
In the state where the slit holes 41 to 43 are opened, natural convection is generated by the low-temperature air in the heat storage body case 34 and the high-temperature air outside the heat storage body case 34.
The low-temperature air in the heat storage case 34 flows out of the slit holes 41 to 43 due to the occurrence of natural convection, and the low-temperature air in the heat storage case 34 that flows out flows around the floor surface of at least one of the driver seat 12 and the passenger seat 13. cool.
The occupant can feel the coldness because the air that cools the vicinity of the floor surface of the driver's seat 12 and the passenger seat 13 is deprived of heat.

By adjusting the opening degree of each shutter 44-46, the amount of heat absorption to the heat storage body 31 by radiation and convection through the corresponding slit holes 41-43 is controlled.
The shutters 44 to 46 are individually opened and closed by the passenger.
Even if each of the shutters 44 to 46 opens the corresponding slit holes 41 to 43, although slow heat absorption is performed on the outer surface of the heat storage case 34, it is compared with heat dissipation through the slit holes 41 to 43. And the effect of cooling the passenger is small.
Thus, the heat absorption of the heat storage body 31 can cool a passenger mainly based on the heat transfer by radiation and the heat transfer via air.

Note that condensed water of moisture contained in the air is generated on the inner surface of the heat storage body case 34 and the outer surface of the heat storage body 31 by the heat absorption of the heat storage body 31.
The condensed water is collected in the conduction path 40 through the bottom plate portion 39, and when the condensed water is stored in the conduction path 40 to some extent, the on-off valve is opened and the condensation water is discharged outside the vehicle.
Since moisture in the air is discharged as condensed water, the humidity in the passenger compartment 11 is lowered, that is, dehumidified.

On the other hand, in a state where the shutters 44 to 46 close the corresponding slit holes 41 to 43, the heat of the heat storage body case 34 is absorbed by the heat storage body 31.
The heat storage case 34 that has been deprived of heat receives heat from the surroundings.
Since the outer surface of the heat storage case 34 is coated with the low heat transfer material 50 having a low heat transfer performance, the heat absorption to the surface of the heat storage case 34 is slow.
Therefore, except for the slow heat absorption to the heat storage case 34 from the outside, the heat storage body 31 is in a state of hardly absorbing heat, and the heat absorption capability as the heat absorption source is maintained.

By the way, in the case of performing heat storage to the heat storage body 31 or heat dissipation of the heat storage body 31 when charging the battery, preheating or heat storage body that warms the vicinity of the driver seat 12 and the passenger seat 13 by heat dissipation of the heat storage body 31 before boarding the passenger. It is possible to perform pre-cooling that cools by 31 endothermic heat.
When pre-heating or pre-cooling is performed, the slit holes 41 to 43 corresponding to the shutters 44 to 46 are closed.
And it energizes to a Peltier device at the time of charge of a battery, and aims at the heat-release source or heat-absorption source of a thermal storage body.
When the heat storage body 31 radiates heat, the vicinity of the driver's seat 12 and the passenger seat 13 is warmed before boarding by the passenger due to slow heat dissipation on the outer surface of the heat storage body case 34.
When the heat accumulator 31 absorbs heat, the vicinity of the driver's seat 12 and the passenger seat 13 is cooled by the slow heat absorption of the outer surface of the heat accumulator case 34 before boarding the passenger.
The driver's seat 12 and the passenger's seat 13 are warmed or cooled by the slow heat dissipation or heat absorption through the outer surface of the heat storage case 34 before the passenger gets on board. The cold or heat in the room 11 is reduced.

According to this embodiment, the following effects can be obtained.
(1) Since the heat storage body unit 30 is installed in the center console 20 in the passenger compartment 11, the heat storage body 31 of the heat storage body unit 30 disposed between the driver seat 12 and the passenger seat 13 is the driver seat 12 and The body of at least one passenger in the passenger seat 13 can be warmed or cooled in a wide range.
(2) Since the heat storage unit 30 is located near the driver seat and the passenger seat, at least one passenger of the driver seat 12 and the passenger seat 13 is likely to receive heat dissipation or heat absorption from the heat storage body 31. Therefore, it is possible to suppress an increase in heat loss due to heat transfer due to long-distance radiation or air convection.
(3) When the heat storage body 31 dissipates heat, at least one of the driver's seat 12 and the passenger seat 13 can be warmed by heat transfer to the passenger due to radiation from the heat storage body 31. When the heat accumulator 31 absorbs heat, heat is absorbed by the heat accumulator 31 by the heat transfer from at least one passenger of the driver seat 12 and the passenger seat 13 to the heat accumulator 31, and the passenger can be cooled.
(4) At least one passenger of the driver's seat 12 and the passenger seat 13 can obtain a warm feeling or cool feeling by directly radiating or absorbing heat of the heat storage body 31 without touching the heat storage body 31 directly.

(5) The heat storage body 31 can perform heat dissipation or heat absorption through the slit holes 41 to 43 of the heat storage body case 34. Since the heat storage body 31 is accommodated in the heat storage body case 34, the contact of at least one of the driver seat 12 and the passenger seat 13 with the heat storage body 31 can be prevented.
(6) Since the opening / closing degree of the slit holes 41 to 43 can be adjusted by the shutters 44 to 46, the amount of heat radiation or heat absorption of the heat storage body 31 performed through the slit holes 41 to 43 can be controlled. By changing the degree of opening and closing of the slit holes 41 to 43, heat transfer due to radiation and convection can be controlled.
(7) Since the outer surface of the heat storage body 31 is formed on the uneven surface 33 </ b> A having unevenness, the surface area on the outer surface of the heat storage body 31 is increased as compared with the case of the outer surface using a flat surface without unevenness.
By increasing the surface area for heat dissipation or heat absorption, efficient heat dissipation or heat absorption of the heat storage body 31 can be performed. Further, since the inner surfaces of the shutters 44 to 46 are mirror-finished surfaces 44A to 46A, the heat hitting the mirror-finished surfaces 44A to 46A is reflected and there is almost no heat loss due to reflection. For this reason, the amount of heat radiation or heat absorption due to radiation passing through the slit holes 41 to 43 can be controlled according to the degree of opening and closing of the shutters 44 to 46.

(8) Since the heat storage unit 30 is installed in the center console 20 in the passenger compartment 11, for example, in the case of heat dissipation by the heat storage body 31, the heat storage case 34 may be radiated. The heat radiation on the outer surface promotes heating of the driver's seat 12 and the passenger seat 13 and helps heating in a low temperature environment. On the other hand, in the case of heat absorption, heat may be absorbed on the outer surface of the heat storage case 34, which helps cooling in a high temperature environment. For this reason, the heat storage body case 34 does not require high heat insulation performance.
(9) For example, when an air conditioner using a refrigeration cycle is separately provided in the vehicle, the air conditioner is provided with a vehicle interior element such as a duct communicating with the vehicle interior. Since the heat storage unit 30 is installed in the center console 20 in the vehicle compartment 11, the vehicle interior elements such as ducts in the air conditioner are located close to the heat storage unit 30. For this reason, for example, when the air in the heat accumulator unit 30 is used for an air conditioner, the heat loss of the air in the heat accumulator unit 30 is reduced and sent to the duct of the air conditioner, and used in the air conditioner. can do.
(10) Since the heat storage unit 30 is installed in the center console 20 in the passenger compartment 11, the heat storage unit 30 is located away from the vehicle window. Even if pre-cooling is performed by heat absorption of the heat storage body 31 before boarding the passenger in a high-temperature environment, the window of the window due to condensation does not occur because the heat storage body unit 30 is located away from the vehicle window.
(11) Since the heat storage unit 30 is installed on the center console 20 in the passenger compartment 11, the heat transfer based on the heat radiation of the heat storage body 31 warms the passenger's legs in a low temperature environment. Warm feeling can be obtained immediately with less heat transfer.

(12) Since the heat storage unit 30 is installed on the center console 20 in the passenger compartment 11 and fixed to the floor surface, electric wiring and piping (such as wiring for Peltier elements and piping) are connected to the heat storage unit 30. Even if it is provided, it can be provided fixed together with the heat storage unit, and installation of electrical wiring and piping is facilitated.
(13) Condensation water of moisture contained in the air is generated on the inner surface of the heat storage body case 34 and the outer surface of the heat storage body 31 due to the heat absorption of the heat storage body 31. Are collected in the conduction path 40 and discharged outside the vehicle. Since moisture in the air is generated in the heat accumulator unit 30 as condensed water and the condensed water is discharged outside the vehicle, the heat accumulator unit 30 can dehumidify the interior of the vehicle compartment 11.
(14) Since the inner surface of the bottom plate portion 39 in the heat storage body case 34 is formed on the mirror-finished surface 34B and the mirror-finished surface 34B reflects heat, the heat absorption to the floor surface of the vehicle body through the bottom plate portion 39 is suppressed. be able to.
(15) Since the inner surface of the heat storage body case 34 is formed on the uneven surface 34 </ b> A having unevenness, the surface area on the inner surface of the heat storage body case 34 increases compared to the case of the inner surface of a flat surface without unevenness. By increasing the surface area of the inner surface for heat dissipation or heat absorption in the heat storage body case 34, efficient heat absorption or heat dissipation of the heat storage body case 34 can be performed.
(16) For example, when the heat storage body is arranged outside the passenger compartment and the heat of the heat storage body is carried into the passenger compartment through the piping (during heating) as in the prior art, the heat is deprived in the piping in the middle, and in the piping The temperature rises, and at the time of cooling, the pipe receives heat in the middle and the temperature falls in the pipe. However, in this apparatus, since the heat storage body 31 is disposed in the passenger compartment 11, there is no need for piping, and there is no phenomenon that heat is taken away or received in the piping, and thermal energy is not generated. Can be efficiently used for air conditioning in the passenger compartment 11.

(Second Embodiment)
Next, the in-vehicle heat storage device according to the second embodiment will be described.
The in-vehicle heat storage device according to the second embodiment is different from the first embodiment in that a blower fan as an airflow generator is provided in the heat storage body case and the structure of the upper shutter.
FIG. 7 shows an in-vehicle heat storage device according to the second embodiment. Among the components, the same elements as those in the in-vehicle heat storage device according to the first embodiment are commonly used with the description of the first embodiment. Is used.

The heat storage unit 60 shown in FIG. 7 includes a heat storage body 31, a heat storage body case 64 that houses and holds the heat storage body 31, and a blower fan 63 provided in the heat storage body case 64.
The heat storage body case 64 is formed of an aluminum-based metal material having a high thermal conductivity.
Of the inner surface of the heat storage body case 64, the inner surfaces of the side plate portion 65 excluding the bottom plate portion 69, the front plate portion (not shown), the rear plate portion (not shown), and the top plate portion 68 have irregularities. It is formed by the uneven surface 64A.
The bottom plate portion 69 of the heat storage body case 64 is formed from an inclined surface that is inclined from the outside toward the center, and the bottom plate portion 69 of the heat storage body case 64 is fixed to the floor surface of the vehicle.
The inner surface of the bottom plate portion 69 is formed by a mirror-finished surface 64B corresponding to the high heat reflecting portion.
A conduction path 70 is formed at the bottom of the bottom plate portion 69.

A storage space for storing the heat storage body 31 is formed in the heat storage body case 64.
In a state where the heat storage body 31 is accommodated, a space S is formed between the outer surface of the heat storage body 31 and the inner surface of the heat storage body case 64.
A plurality of slit holes 71 and 72 as through holes are formed in the side plate portion 65 on the driver seat side and the side plate portion 65 on the passenger seat side in the heat storage body case 64, and the slit hole 73 is also formed on the upper surface of the heat storage body case 64. Is formed.
The configuration of these slit holes 71 to 73 is the same as the slit holes 41 to 43 of the first embodiment.

The heat storage case 64 includes shutters 74 to 76 as opening / closing bodies that open and close the slit holes 71 to 73.
The side shutter 74 that opens and closes the slit hole 71 on the driver's seat side opens and closes the slit hole 71 by rotating about a fulcrum shaft 77 provided on the upper portion of the slit hole 71.
Although not shown, the fulcrum shaft 77 is provided with a coil spring (not shown) as an urging member for urging the side shutter 74 in the direction of closing the slit hole 71.
The opening and closing of the side shutter 74 in this embodiment is performed in conjunction with the operation of the blower fan 63, and when the wind pressure in the heat storage body case 64 exceeds a certain level, the side shutter 74 starts to open the slit hole 71.
The adjustment of the degree of opening / closing of the slit hole 71 by the side shutter 74 depends on the wind pressure based on the air flow generated by the operation of the blower fan 63, and when the air pressure falls below a predetermined wind pressure, the side shutter 74 is slit by the biasing force of the coil spring. 71 is closed.
The side shutter 75 of the passenger seat side slit hole 72 has basically the same configuration as the side shutter 74 and opens and closes in conjunction with the operation of the blower fan 63 with the fulcrum shaft 78 as a fulcrum.
The fulcrum shaft 78 is provided with a coil spring (not shown) as a biasing member that biases the side shutter 74.

The upper shutter 76 of the slit hole 73 provided in the top plate portion 68 is provided with a fulcrum shaft 79 so as to cross the vicinity of the center of the slit hole 73.
The upper shutter 76 is opened and closed in conjunction with the operation of the blower fan. When the wind pressure based on the airflow in the heat storage body case 64 exceeds a certain level, the upper shutter 76 opens the slit hole 73.
When the upper shutter 76 is rotated so as to open the slit hole 73, the upper shutter 76 is inclined.
In the state in which the upper shutter 76 is inclined, the outer portion located outside the fulcrum shaft 79 in the upper shutter 76 is displaced upward, and the inner portion located inside the fulcrum shaft 79 in the upper shutter 76 is downward (inside the space S ).
For this reason, in the slit hole 73, the upper shutter 76 is partitioned and the two paths for communicating the space S and the outside are two.
Since the weight of the outer portion of the upper shutter 76 is set to be greater than the weight of the inner portion, the upper shutter 76 closes the slit hole 73 when the air pressure becomes a predetermined wind pressure or less.
As described above, in this embodiment, the side shutter 74 and the upper shutter 76 are configured to be opened by the force of the airflow generated by the blower fan 63.

On the other hand, the inner surfaces of the shutters 74 to 76 are made of an aluminum-based metal material, but mirror-finished surfaces 74A to 76A are formed as high heat reflecting portions having excellent heat reflectivity.
For this reason, for example, when the heat dissipated from the heat storage body 31 strikes the inner surfaces of the mirror-finished surfaces 74A to 76A, this heat is reflected by the mirror-finished surfaces 74A to 76A, and hardly causes heat loss.
In a state where the shutters 74 to 76 open the corresponding slit holes 71 to 73, the heat due to the radiation of the heat storage body 31 is reflected on the inner surfaces of the shutters 74 to 76 and radiated to the outside of the heat storage body case 64.
That is, the heat of radiation of the heat accumulator 31 is further transferred to the outside of the heat accumulator case 64 using the reflection of the mirror-finished surfaces 74A to 76A of the shutters 74 to 76.

The outer surface of the heat storage case 64 is coated with a resin that is a low heat transfer material 80 having a heat transfer performance lower than that of the heat storage case 64.
For example, if the temperature of the heat storage material 32 is near the boiling point or the melting point, the passenger may feel excessively hot or excessively cold even if the passenger contacts the outer surface of the heat storage case 64. There is no.
In this embodiment, the low heat transfer material 80 is also coated on the outer surfaces of the shutters 74 to 76.
Thus, the heat storage body case 64 which accommodates the heat storage body 31 has a heat insulation function and a heat absorption function with respect to the periphery, while having a fixed heat insulation function.

Next, the blower fan 63 will be described.
In this embodiment, the ventilation fan 63 is installed in the space S between the upper part of the heat storage body 31 and the upper part of the heat storage body case 64 in which the slit hole 73 is formed.
The blower fan 63 corresponds to an airflow generator that generates an airflow in the space S, and is driven by energization.

According to the in-vehicle heat storage device according to this embodiment, an air flow is generated in the space S by the operation of the blower fan 63.
The shutter 76 opens the slit hole 73 by the wind pressure of the airflow by the operation of the blower fan 63.
When the wind pressure due to the airflow in the space S exceeds a predetermined value, the shutters 74 and 75 begin to open the corresponding slit holes 71 and 72 against the biasing force of the coil spring.
When the shutters 75 to 76 open the slit holes 71 to 73, heat transfer due to radiation through the slit holes 71 to 73 and heat transfer due to forced convection occur between the heat storage body 31 and the outside of the heat storage case 64. .

When the heat storage body 31 dissipates heat, the passenger can be warmed by radiation and forced convection through the slit holes 71 to 73.
Moreover, when the heat storage body 31 absorbs heat, the passenger can be cooled by radiation and forced convection through the slit holes 71 to 73.
By controlling the rotational speed of the blower fan 63, the amount of heat released to the outside of the heat storage body case 64 by the heat storage body 31 through the slit holes 71 to 73 or the amount of heat absorbed from the outside of the heat storage body case 64 can be controlled. .
When the blower fan 63 stops or the wind pressure in the space S becomes less than a predetermined value, the side shutters 74 and 72 close the corresponding slit holes 71 and 69 by the urging force of the coil spring provided on the fulcrum shafts 77 to 79.
On the other hand, the upper shutter 76 closes the slit hole 73 by the weight of the outer portion.

This embodiment has substantially the same operational effects as the operational effects other than the operational effect (2) of the first embodiment.
Further, the amount of heat dissipation or heat absorption through the slit holes 71 to 73 is controlled according to the rotational speed of the blower fan 63.
For this reason, compared with the heat transfer by radiation and natural convection, a quick heat transfer can be achieved, and compared with the case where there is no ventilation fan 63, the heating capability or the cooling capability of the thermal storage unit 60 is improved.

In addition, the vehicle-mounted heat storage device according to the first and second embodiments shows an embodiment of the present invention, and the present invention is not limited to the above-described embodiment, and is as follows. Various modifications are possible within the scope of the invention.
In the first and second embodiments, the shutter as the opening / closing body is a rotary shutter having a fulcrum shaft as a fulcrum, but, for example, a sliding shutter that opens and closes a slit hole as a through hole by sliding movement It may be. Further, the opening / closing body may be an automatic opening / closing type that is automatically opened / closed by a driving source, or may be a manual opening / closing type that is opened / closed by an operation of a passenger.
In the first and second embodiments, the inner surface of the heat storage case is an uneven surface that absorbs heat of radiation, but for example, the amount of heat radiation or heat absorption of the heat storage to the driver seat or the passenger seat can be accurately controlled. As described above, when the through hole and the opening / closing body are sufficiently secured in the heat storage body case, a high heat reflecting portion that reflects heat like the inner surface of the opening / closing body may be formed on the inner surface of the heat storage body case. The high heat reflecting portion can be formed by mirror finishing of the case body or vapor deposition of an aluminum metal material. In this case, the heat radiated from the heat storage body or the heat absorbed by the heat storage body is reflected by the high heat reflecting portion of the heat storage body case, and heat loss of radiation to the heat storage body case can be suppressed. That is, the heat insulation performance of the heat storage body case can be improved.
In the first and second embodiments, the in-vehicle heat storage device mounted on a plug-in hybrid vehicle (referred to as “PHEV”) as a vehicle has been described, but the present invention may be applied to an electric vehicle in addition to PHEV. Good. Alternatively, the present invention can also be applied to an air conditioner of a hybrid vehicle (referred to as “HEV vehicle”) excluding a PHEV vehicle and an automobile (referred to as “engine vehicle”) equipped only with an internal combustion engine.
In the first embodiment, the through hole is closed by the opening / closing body and the pre-heating or pre-cooling is performed. However, for example, the pre-heating or the pre-cooling may be performed in a state where the through-hole is opened. In this case, pre-heating or pre-cooling can be quickly performed as compared with the case of closing the through hole. However, in pre-heating or pre-cooling in a state where heat is not continuously stored in the heat storage material without being energized from an external power source, such as after battery charging, It is preferable to set the opening / closing degree of the through hole by the opening / closing body in consideration of the ability of the heat storage body to release heat or absorb heat.
○ In the second embodiment, the air flow generator is a blower fan provided in the heat storage body case. However, the air flow generator can be installed outside the heat storage body case as long as the opening and closing body can be opened by the generated air flow. May be provided. Or you may use the ventilation fan of the air conditioner provided separately as an airflow generator.
○ In the first and second embodiments, all of the outer surface of the heat storage case is coated with the low heat transfer material. However, the low heat transfer material is not all of the outer surface of the heat storage case, but a part thereof. Also good. For example, a low heat transfer material may be partially coated to balance the heat insulation performance and heat dissipation performance of the heat storage case. In addition, a plurality of types of low heat transfer materials may be combined, or even when a single low heat transfer material is used, the low heat transfer material may have a different thickness depending on the part.
In the first and second embodiments, the heat storage unit is fixed to the vehicle floor, but the heat storage unit and the heat storage unit may be detachable. In this case, the heat storage material can be turned into a heat radiation source or a heat absorption source at a place different from the vehicle.
In the first and second embodiments, the heat storage body is supported by the support member in the heat storage body case. For example, the heat storage body may be supported by the lower part of the heat storage body case without using the support member.
○ In the first and second embodiments, the heat storage unit is arranged between the foot space of the driver's seat and the foot space of the front passenger seat, but not between the driver seat and the front passenger seat. May be. For example, the heat storage unit may be installed on the center console between the driver seat and the passenger seat.
