DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a glove box installed in an automobile, and particularly to a technique for cooling the glove box.

(Prior Art) In general, this type of automotive glove box is
It is installed on the instrument panel at the front end of the passenger compartment and is used to store various small items.

(Problem to be Solved by the Invention) By the way, since this glove box is installed inside the instrument panel, for example, under the scorching sun in summer, sunlight entering through the window glass can cause the internal temperature of the sealed state to become high. rise to Therefore, in reality, under the above-mentioned circumstances, it is impossible to store small items such as a camera and its film inside the glove box that are sensitive to high temperatures, resulting in a problem that the glove box is inconvenient to use.

The present invention has been made in view of the above points, and its purpose is to efficiently cool a glove box by a predetermined means, even if there are small items inside the glove box that would cause an inconvenient temperature rise. The idea is to be able to store it without any problems.

(Means for Solving the Problems) In order to achieve the above object, the solution of the present invention is to install a tube in an electronic cooling element called a Peltier element, which generates a temperature gradient between a heat absorption part and a heat radiation part when energized. The heat absorbing part is arranged inside the glove box, and the heat radiating part is arranged outside, respectively, and the heat is radiated from the heat radiating part by the conditioned air flowing in the duct of the vehicle air conditioner.

Specifically, the automobile glove box of the present invention is installed in an automobile equipped with an empty and necessary duct to store small items. The heat absorbing part of the electronic cooling element that generates a temperature gradient between the heat absorbing part and the heat dissipating part are respectively disposed outside. and,
A heat radiating means for radiating heat from a heat radiating portion of the electronic cooling element is provided in the air conditioning duct.

(Function) With the above configuration, in the present invention, when the electronic cooling element is energized, a temperature gradient occurs between the heat absorption part and the heat radiation part,
The temperature of the heat absorption part becomes lower than that of the heat radiation part. This heat absorbing part is placed inside the glove box, and the heat radiating part is placed outside the glove box, so even if the glove box is heated by sunlight and its temperature rises, the internal temperature remains low. Therefore, even small items that would be inconvenient if the temperature rises can be stored without any problem.

Furthermore, the heat dissipation section is disposed outside the glove box, and the heat dissipation means in the air conditioning duct exchanges heat with the conditioned air to radiate heat, so the heat dissipation of the heat dissipation section is continuously stabilized. As a result, the interior of the glove box can be efficiently maintained cooled by the heat absorbing section.

Further, although not shown, the center blow-off duct 12 has an outside air inlet that is opened to the outside of the vehicle by a door only when the air conditioner 3 is not in operation, such as when parking, and a ventilation fan 16 is disposed in the outside air inlet. The fan 16 is connected to a solar battery 17 attached to the roof of the vehicle body, and when the air conditioner 3 is not operating, the ventilation fan 16 is operated by the output of the solar battery 17 to blow outside air to each outlet 13°. The interior of the vehicle is ventilated by blowing air from 14.

Additionally, on the left side of the instrument panel 1 (passenger seat side), there is a glove box 1 for storing small items.

It is made up of a rectangular plate-shaped heat absorbing part 21 and a heat radiating part 22 that can be inserted into the opening 18b, and a temperature gradient is created in which the temperature of the heat absorbing part 21 is lower than that of the heat radiating part 22 when electricity is supplied from the solar cell 17. be. The heat absorbing part 21 is arranged inside the glove box 18, and the heat absorbing part 21 is made of brass bent into an L shape so as to cover substantially the inner bottom half or the entire inner inner surface of the glove box 18. A heat transfer plate 23 made of a thermally conductive material such as the like is integrally attached, and an elastic plate 24 made of rubber or the like is fixed to the surface of the heat transfer plate 23.

On the other hand, the heat radiation part 22 of the electronic cooling element 20 faces the outside of the glove box 18, and the heat vibration part 22 is provided with a heat vibrator 2.
5 is joined to enable heat transfer, and the heat vibrator 25
The other end penetrates the wall of the left branch duct 15 and faces the inside thereof, and the other end has a large number of fins 26.26. ... are installed at regular intervals. Therefore, in this embodiment, the left branch duct 15 is the air conditioning duct according to the present invention, and the fins 26 and 26 disposed inside it are
, . . . constitute a heat radiating means for radiating heat from the heat radiating section 22 of the electronic cooling element 20.

In FIG. 1, 27 is a defroster nozzle having a differential air outlet 27a opening toward the inner surface of the window glass 2, and 28 is a differential duct for connecting the defroster nozzle 27 and the heater unit.

Therefore, in the embodiment described above, when the air conditioner 3 is in an inactive state, for example when the car is parked, the ventilation fan 16 is operated by the output of the solar cell 17, and the operation of the fan 16 causes the outside air to flow into the center blowing duct. This outside air is sucked in from the outside air inlet 12, and is blown out into the vehicle interior from the center louver air outlet 13.13, and passes through the left and right branch ducts 15.15 to the side louver air outlet 14.

This allows the interior of the vehicle to be ventilated.

Also, during this time, the electronic cooling element 20 is energized by the output of the solar cell 17. With this energization, the heat absorption part 2
A temperature gradient occurs between the heat sink 1 and the heat sink 22, so that the temperature of the heat sink 21 disposed inside the glove box 18 is higher than that of the heat sink 2.
It will be lower than 2. Therefore, even if the instrument panel 1 and the glove box 18 are heated by sunlight passing through the windshield 2 and the temperature rises, the temperature inside the instrument panel 1 and the glove box 18 will be kept low by the heat absorbing section 21 whose temperature has decreased. Even small items such as cameras and film that are susceptible to temperature rise can be stored in the glove box 18.

Furthermore, the heat radiation section 22 whose temperature increases is arranged outside the glove box 18, and the heat vibration section 22 is connected to the fins 26, 26.・
... (heat radiating means) are connected so that heat can be transferred, the thermal energy of the heat radiating part 22 is transmitted through the heat vibrator 25 and reaches the fins 26, 26°..., and the fins 26, 26
．． . . . heat is exchanged with the ventilation air conditioned air in the duct 15 and radiated. As a result, the heat dissipation section 22
By continuously dissipating heat, the inside of the glove box 18 can be efficiently kept cool by the heat absorbing section 21.

Furthermore, since the air conditioner 3 is activated when the vehicle is driven, cold conditioned air cooled by a cooler unit, for example, flows through each of the branch ducts 15 instead of outside air for ventilation. At this time, the heat radiation effect of the heat radiation part 22 of the electronic cooling element 20 increases, and the inside of the glove box 18 can be cooled even more effectively.

Further, since the heat absorbing part 21 of the electronic cooling element 20 is joined to the large-area heat transfer plate 23 in a heat transferable manner, the contact area between the air inside the glove box 18 and the cooling part can be increased, and the glove box 18 The interior can be cooled even more efficiently.

Furthermore, since an elastic plate 24 made of rubber or the like is fixed to the surface of the heat transfer plate 23, small items stored in the box 18 will not come into direct contact with the heat transfer plate 23, and the small items will be reliably protected. can do.
