The present invention relates to a cold storage device for automobiles, which are installed in automobiles and stores canned beverages in a cold temperature state, and more particularly, by using endothermic action and exothermic action generated by the Peltier effect of the thermoelectric element. It relates to a cold storage device for a vehicle using a thermoelectric element to achieve a cold and of course as well as to clean the air.

Recently, as the spread of automobiles, especially private cars, has increased, the culture of automobiles has become an important part of daily life. Accordingly, consumer demands have diversified, and the development of automobiles has been competitively developed to meet these consumption needs. Has been made.

Such automobile development has been progressed in the direction of improving the basic performance of the vehicle and in the direction of improving additional functions.

In order to improve the additional functions of the vehicle, various specifications for the convenience of driving the vehicle have been developed and applied to the actual vehicle, and one of these specifications is a cold / hot device installed in the vehicle interior.

In the case of a refrigerator in a vehicle built-in small refrigerator or cold storage, such a cold and cold device is the most basic form, and the operation principle, form, and function of the conventional refrigerator are the same, and the size is small enough to be mounted inside the vehicle only in size. Has been developed.

Since these refrigerators have the same cooling system as the conventional refrigerators, they need to be equipped with a large number of additional components as equipment for supplying power, thereby increasing the space required to be built into the vehicle and increasing the volume of the refrigerator itself. Since the effective refrigeration volume is reduced, as well as the mounting efficiency is lowered, there is a problem in that the cost increases with the addition of parts.

In addition, each component constituting the cooling system had a disadvantage of causing vibration and subsequent noise during operation of the refrigerator.

On the other hand, the above-mentioned cold and cold refrigerator is a more improved form than the refrigerator, as shown in Figure 1, the lid 102 is covered with the top opening of the body 101 made of a heat insulating outer wall, the body 101 The air inlet tube 104 with the filter 103 attached to the lower wall of the bottom penetrates from the outside to the inside, and is closely connected to the cooling / heating and cooling vents 105 for cooling and heating, which are basically installed at the front of the vehicle. The intake cylinder 106 is connected to the injection pipe 104 and the blowing hose 107 through, and is configured such that the suction fan 108 is installed through the upper wall of the body 101.

The cold and cold storage configured as described above can be used as a refrigerator when supplying cool air by adjusting the temperature of the air supplied through the cold and hot air outlets 105 according to the season, that is, by supplying hot air when the hot air is supplied. There is the following to explain the cold and hot process.

First, cold air discharged from the cold / hot air outlet 105 of the air conditioning system is introduced into the cold / cold chamber surrounded by the cold / cold cabinet body 101 through the air inlet tube 104 from the intake cylinder 106 via the blow hose 107.

At this time, the air is more smoothly introduced by the suction fan 108 and foreign matters are removed by the filter attached to the air inlet tube.

Cold and cold storage of the cold and hot products stored in the heat-insulated body 101 by the introduced air is made, the user of a cold and cold, such as a driver can open the lid 102 to take out the product of the cold and cold state. .

Such a cold and cold storage can be used as a combined cold and cold storage, and may be referred to as a more improved form because it does not require a separate device for making cold and warm air, but there are some problems like the refrigerator mentioned above.

In other words, such a conventional cold and hot refrigerator not only reduces the cooling and heating efficiency inside the vehicle by deducting the cold or hot air supplied from the hot and cold air vents for use in air conditioning, but also the cold and cold storage refrigerator function can be used only in parallel with the cooling of the car. Therefore, if the cooling in the car is unnecessary, that is, it is not suitable for use in other seasons other than the summer when the temperature is high, and the warming function is not suitable for other seasons other than the low temperature, such as the above-mentioned refrigeration function. There was a disadvantage in that the heating and cooling system and the cold and cold function cannot be used independently.

On the other hand, as a form using a principle similar to the refrigerating function of the cold storage, there has been developed a refrigeration apparatus using a rear cooling system for the occupant in the rear of the car, that is, the rear seat, the refrigeration apparatus using such a rear cooling system As shown in FIG. 2, a suction port 203 is formed on one side and penetrates upwardly while forming a predetermined fluid passage therein, and has a blower tube 206 connected to the vehicle through the other side.

It consists of a dryer connected through the filler tube 216 and a heat dissipating condenser connected adjacent to the dryer, but only the evaporator 205, the absorption tube 215 and the capillary tube 216 are shown. The components are not shown.

A control valve 218 is provided in the absorption tube 215.

While controlling the driving speed of the centrifugal fan 204 while sensing the amount of air sent out from the centrifugal fan 204, a blower control unit 220 for sensing the amount of air sent out is the rear of the centrifugal fan 204. Installed in

An outlet 213 is provided on the upper surface of the refrigerating duct 211 so that the introduced cold air flows into the vehicle through the refrigerating box 212.

On the other hand, the one side wall of the internal passage of the refrigeration duct 201 between the centrifugal fan 204 and the evaporator 205 is formed through the polluted air outlet 209 through which the blown air is discharged to the outside through the trunk, In the passage between the polluted air outlet 209 and the evaporator 205, the blown air is alternatively blocked in the passage between the polluted air outlet 221 and the evaporator 205 side for cooling, refrigeration mode or pollution. First opening and closing means for selecting the air discharge mode is provided.

In addition, the inlet passage of the refrigeration duct 211 penetrated from the cooling duct 201 and the inlet passage of the blower tube 206 are alternatively blocked, so that the blocked side passage is cooled from the evaporator 205 of the cooling system. And a second opening and closing means for selecting a rear cooling only mode or a refrigeration only mode to allow a small amount of cool air to be blown and to allow a large amount of cool air to flow to the other side not blocked. It is installed.

As an example, the second opening and closing means rotates by the second driving motor 221 and the second driving motor 221 to block the cold air inflow passage of the refrigerating duct 211 when selecting the rear refrigeration only mode. The second barrier layer 222 blocking the inflow passage of the blower tube 206 and the second barrier layer 222 perpendicular to the second barrier layer 222 when the refrigeration only mode is selected, and the one side passage in which the second barrier layer 222 is blocked. It consists of an inlet hole 223 to allow a small amount of cold air to flow.

The refrigerating device using the rear cooling system configured as described above is intended to cool the refrigerating box 212 by introducing cold air cooled by the inlet air from the vehicle and cooled by the evaporator 205 of the cooling system into the refrigerating duct 211. The refrigeration process is as follows.

By operating the first opening and closing means can be selected polluted air discharge mode or cooling, refrigeration mode, first select the polluted air discharge mode to discharge the air in the car to the outside by smoking or odor, etc. of the first drive motor 207 By the operation, the first blocking membrane 208 rotates in the opposite direction to block the air inflow passage to the evaporator 205 to open the polluted air outlet 209 that penetrates to the outside.

As the centrifugal fan 204 operates, the air sucked through the inlet 203 from the inside of the vehicle is sent out to the rear while the foreign matter such as dust is filtered out by the filter 202 installed therein, so that the filtered air is polluted. It is discharged to the outside of the vehicle through the air outlet 209.

Next, when the cooling and cooling mode is selected by operating the first opening / closing means to achieve cooling or refrigerating of the refrigerating box 212 at the rear of the vehicle, air on the evaporator 205 side is operated by the operation of the first driving motor 207. The first blocking membrane 208 which blocked the inflow passage is rotated again to block the polluted air outlet 209 and open the air inflow passage on the evaporator 205 side.

As the centrifugal fan 204 operates, the air sucked into the intake port 203 from the inside of the vehicle is filtered out of the foreign matter such as dust through the filter 202, that is, sent out to the rear, that is, the evaporator 205.

The cooling system operates at the same time as the cooling and refrigeration modes are selected. When the process is briefly described, the high-pressure compressed refrigerant in the compressor is introduced into the evaporator 205 through the absorption tube 215 to be vaporized. The amount of heat consumed by the vaporization heat absorbs the surrounding heat, thereby lowering the ambient temperature, that is, cooling the air blown from the blower.

Cooling can be achieved exclusively.

On the other hand, when the refrigerating-only mode of the second opening and closing means is selected, the second blocking membrane 222 which is blocking the cold air inflow passage of the refrigerating duct 211 is rotated again by the operation of the second drive motor 221 while being reversed. By blocking the cold air inflow passage of the blower pipe 206, the cold air is introduced into the refrigeration duct 211, it is possible to quickly cool the refrigerating box 212 to store the contents inside the refrigerator, only a small amount of cold air Through the inlet hole 223 formed in the second blocking membrane 222 to be introduced into the blower tube 206 to eject only a small amount of cold air to the occupant of the rear seat, it is possible to achieve the refrigeration of the refrigerating box 212 exclusively.

Prior to entering the description of the working effects of the present invention, first, the operation of the thermoelectric element 20 will be briefly described. The thermoelectric element is connected through two metal junctions when two different N and P-type semiconductor elements are connected in series. It refers to a device that uses the Peltier effect that heat is generated or absorbed at the junction when current flows. When heat flows in a direction and reverses the direction of current when heat is generated, heat is absorbed.

Referring to the effects of the present invention configured as described above are as follows.

According to the first embodiment of the present invention, first, the cans of beverages are opened by putting the lid 14 into the contents storage container 13, and then selecting the refrigerating function mode through the control device for refrigeration storage, In the apparatus, the thermoelectric element 20 is supplied with a current in an appropriate direction according to the refrigerating function mode selection. At this time, the thermoelectric element 20 supplied with the current generates an endothermic action on the upper side and an exothermic action on the other side by the Peltier effect as described above.

By absorbing heat around the thermoelectric element 20 by the endothermic action, that is, absorbing the heat of the contents storage container 13 through the aluminum block 23, the contents storage container 13 is cooled. At this time, thermal conductivity is smoothly achieved by a carbon plate or a thermally conductive glass plate in which the adhesion layer 24 is formed between the aluminum blocks 22 and 23 and the thermoelectric element 20.

The contents storage container 13 according to the endothermic action is cooled to cool the contents of the internal air and beverages, etc., and in this state the internal air circulation fan 15 installed in the lower portion of the lid 14 is in operation. By circulating the internal air of the reservoir 13 to prevent the cooling is made locally only on the bottom surface side, by activating the heat convection in the air to distribute the cold evenly, the cold air in the contents reservoir 13 so cooled Is to minimize the heat loss to the outside by the heat insulating material 12 and the heat insulating case 11 surrounding it.

The temperature of the contents reservoir 13 cooled by the thermoelectric element 20 is measured by a thermocouple instrument 25. When the measured temperature value reaches a predetermined value, the thermoelectric element ( 20) Cut off the current or reduce the amount of current supplied. After the supply of the current is cut off or the supply amount of the current is reduced, when a certain time elapses and the internal temperature of the contents reservoir 13 rises due to heat loss, the thermocouple meter 25 detects this again. The current is supplied to the thermoelectric element 20 again to cool the content reservoir 13.

In this process, the contents chilled in the contents storage container 13 can be used by opening the lid 14 and then removing the contents.

On the other hand, in the lower surface of the thermoelectric element 20, as described above, a lot of heat is generated that is opposed to the endothermic action, the generated heat is generated through the heat sink 21 attached thereto.

The refrigeration function through the thermoelectric element 20 according to this process is because the rapid dissipation of heat generated by the exothermic action will affect the performance of the entire apparatus, so that the heat transferred to the heat sink 21 air circulation duct 31 Blown fan 34 installed in the) is heated while operating, looking at the process according to the operation as follows.

By operating the opening and closing means provided between the passage on the heat sink 21 side and the polluted air outlet 40, it is possible to select the polluted air discharge mode or the cooling mode, and first to pollute the air to discharge the in-vehicle air to the outside by smoking or odor, etc. When the air discharge mode is selected, the blocking film 39 rotates by the operation of the driving motor 38 to block the air inflow passage of the heat sink 21 to open the polluted air outlet 40 penetrated to the outside of the vehicle.

The air sucked into the inlet 32 from the inside of the vehicle by the operation of the blowing fan 34 is filtered through the filter 33 and is sent out to the rear through the trunk through the polluted air outlet 40 while being discharged to the rear. Will be discharged.

Next, when the cooling mode is selected by operating the opening and closing means, the blocking film 39 which blocks the air inflow passage on the heat sink 21 side by the operation of the driving motor 38 is rotated again to reverse the polluted air outlet 40. To block the air inlet passage on the heat sink 21 side.

As the blower fan 34 operates, the air sucked into the intake port 32 from the inside of the vehicle is filtered by the foreign matter such as dust through the filter 32 and forcedly blown to the rear, that is, the heat sink 21.

The forced air is blown into the vehicle through the outlet pipe 35 on the rear side along the groove 21b between the heat radiation fins 21a formed on the heat sink 21.
