Description

[Detailed Description of the Invention] The present invention relates to a structure for mounting a cold/hot storage in a passenger vehicle.

Conventionally, a cold/hot storage is constructed in which a common thermoelectric element is incorporated into the storage body that defines the refrigerator compartment and the greenhouse compartment, and this thermoelectric element absorbs heat from the refrigerator compartment and generates heat from the greenhouse compartment at the same time. Those mounted on the vehicle body are known (see, for example, Japanese Utility Model Application No. 193177/1983).

However, in the conventional structure described above, when the cold/hot storage is disposed in the trunk room, it is inconvenient to take out food and drinks from the cold/hot storage only when the passenger vehicle is stopped. Furthermore, in order to be able to use the refrigerator while the passenger vehicle is running, it is possible to bring the cold/hot storage into the passenger compartment, but this poses a problem in that the space occupied by the cold/hot storage makes the passenger compartment narrow.

The present invention was developed in view of the above circumstances, and has a simple structure that allows the use of a cold storage, that is, the storage and removal of food and drinks even when the passenger vehicle is running, without reducing the space inside the vehicle. The purpose of the present invention is to provide a mounting structure for a cold storage in a passenger vehicle.

According to the present invention, in order to achieve the above object, there is provided a storage body defining a refrigerator compartment and a greenhouse compartment with each opening facing the passenger compartment, and a storage body disposed inside the storage compartment with a heat generating surface. A thermoelectric element facing the greenhouse and a cooling heat conductor connecting the heat absorption surface of the thermoelectric element and the refrigerator compartment are embedded in the door of a passenger vehicle, and a lid that closes each opening is installed in the vehicle. At least a portion of the storage body is disposed to be openable and closable from the interior, and at least a portion of the storage body is formed to bulge from the inner surface of the door toward the vehicle interior so that at least one of the lids functions as an armrest of the door, and A heat conductor for heat dissipation is disposed across the inner wall of the hot storage room and the outer surface of the door.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. First, in FIG. The person sitting in the passenger compartment 2 can take out food and drink from the refrigerator 4 and the hot storage 5 in the passenger compartment 6.

Referring to FIGS. 2 and 3 together, door 3
Inside, there is a storage body 8 defining a cold storage compartment 7 of the refrigerator 4 and a hot storage compartment 20 of the hot storage 5, a thermoelectric element 11 having a heat generation surface 9 and a heat absorption surface 10, and the heat absorption surface 1.
A cooling heat conductor 12 connecting the refrigerator compartment 7 and the refrigerator compartment 7 is buried therein.

The storage body 8 formed of a heat insulating material is connected to the door 3 with the opening 13 of the refrigerator compartment 5 facing upward and the opening 25 of the greenhouse compartment 20 facing the compartment 6 side at the lower side. The thermoelectric element 11 is buried on its heat absorption surface 1
It is disposed at the lower part of the middle wall of the storage body 8 with 0 facing upward. A heat absorbing plate 14 is housed and arranged in the lower part of the refrigerator compartment 7 with a heat absorbing area as large as possible, and one end of the cooling heat conductor 12 is connected to this heat absorbing plate 14. The cooling thermal conductor 12 is formed by laminating a plurality of sheets of a material with good thermal conductivity, such as aluminum plates, and extends downward through the intermediate wall of the storage body 8 . Moreover, the other end of the cooling heat conductor 12 is joined to the heat absorption surface 10 of the thermoelectric element 11 .

The thermoelectric element 11 is a known one, and a DC power source such as a battery mounted on the passenger vehicle 1 is connected between a pair of current-carrying terminals. When a direct current is applied to this thermoelectric element 11, heat is absorbed by the heat absorption surface 10, and the heat is emitted from the heat generation surface 9.

The lid 15 that closes the opening 13 of the storage body 8 has a hinge 1 at the upper end of the storage body 8 so that it can be opened and closed from inside the vehicle compartment 6.
6, and a recess 17 and a holding hole 18 for holding a cup, can, etc. are provided on the inner surface side of the lid 15, that is, on the upper surface side when opened. Thereby, the lid 15 functions as a tray when it is opened.

An inner lid 19 is disposed inside the lid 15 in the opening 13 . This inner lid 19 is for preventing cold air from escaping from the refrigerator 7 when the lid 15 is opened and used as a tray, and is formed into a bellows shape, for example, and is provided so as to be openable and closable from side to side. .

On the other hand, the opening 25 of the hot storage compartment 20 of the hot storage 5
A lid 21 for opening and closing is rotatably disposed on the compartment 6 side. Moreover, the heat generating surface 9 of the thermoelectric element 11 faces the upper part of the hot storage chamber 20, and the inside of the hot storage 5 is heated by heat radiation from the heat generating surface 9.
Further, between the inside of the hot storage room 20 and the outer surface 22 of the door 3, a heat dissipating thermal conductor 23 made of, for example, laminated aluminum plates is removably disposed. Therefore, the heat released from the heat generating surface 9 warms the inside of the greenhouse 20, and a part of the heat is also released from the outer surface 22 of the door 3, causing the temperature inside the greenhouse 20 to become abnormal. This prevents the thermoelectric element 11 from increasing in temperature and impairing the cooling effect of the thermoelectric element 11.

The upper half of the refrigerator body 8 that defines the refrigerator compartment 7 is formed to bulge out from the inner surface of the door 3, thereby making it possible to secure a sufficient effective capacity of the refrigerator compartment 7 and also to expand the storage space. Lid 1 of opening 13 in upper wall of body 8
5 can function as an armrest on which the occupant's elbow near the door 3 is placed.

Next, the operation of this embodiment will be explained. By energizing the thermoelectric element 11, heat is absorbed on the heat absorption surface 10, and the refrigerator compartment 7 is cooled through the cooling heat conductor 12 and the heat absorption plate 14. Therefore, the food and drinks in the refrigerator compartment 7 are cooled. On the other hand, the absorbed heat is released from the heat generating surface 9, and the inside of the refrigerator 5 is heated. Therefore, the food and drinks stored in the hot storage room 5 are kept warm.

In order to take out food and drink from such a refrigerator 4 or hot storage 5, it is only necessary to open the lid 15 and inner lid 19 of the refrigerator 4, or the lid 21 of the hot storage 4. Items can be taken out and stored easily. Also, lid 1 of refrigerator 4
If the lid 5 is left open, food and drink can be placed on the lid 15 and used as a tray, which is convenient.

When the refrigerator 4 or the hot storage 5 is not used, the lids 15 and 21 may be kept closed, and in this state the lid 15 can be used as an armrest.

In such a refrigerator 4 and hot storage 5,
Since the thermoelectric element 11 is used as the cooling source and heat source, no operating noise is generated, and therefore the interior of the vehicle compartment 6 is kept quiet.

As described above, according to the present invention, there is provided a storage body that defines a refrigerator compartment and a greenhouse compartment with each opening facing the passenger compartment, and a storage body that is disposed inside the storage compartment and has a heat generating surface that is connected to the greenhouse compartment. A thermoelectric element facing the front and a cooling heat conductor connecting the heat absorption surface of the thermoelectric element and the refrigerator compartment are embedded in the door of a passenger vehicle, and a lid that closes each opening can be opened and closed from inside the vehicle. Further, the door is provided with a heat conductor for heat dissipation across the wall of the hot storage chamber and the outer surface of the door, so that even when the vehicle is running, the cold and hot temperature buried in the door is disposed. Food and drinks in the storage room can be taken out from inside the vehicle without difficulty.
It's convenient. Moreover, since the interior space of the door, which is originally a dead space, can be used as a space for installing a cold/hot storage, the effective space of the passenger compartment is hardly reduced even if a cold/hot storage is installed.
Furthermore, since the heat conductor for heat radiation is disposed across the wall of the greenhouse chamber and the outer surface of the door, a portion of the heat emitted from the heat radiation surface of the thermoelectric element and heated inside the greenhouse chamber is transferred from the outside surface of the door. The thermoelectric element can be discharged smoothly, thereby suppressing excessive temperature rise in the greenhouse and keeping the function of the thermoelectric element always effective.

Further, at least a portion of the storage body is formed to bulge out from the inner surface of the door toward the passenger compartment so that at least one of the lids functions as an armrest of the door. A wide effective space in the greenhouse can be secured, and since the one lid is also used as the armrest of the door, there is no need to provide a special armrest, contributing to the simplification of the structure.
