Description

Car refrigerator The present invention relates to a refrigerator for automobiles, and in particular to a refrigerator installed inside a vehicle, and provides excellent cooling efficiency while minimizing battery consumption when the engine is off. Currently, most car refrigerators use the car's battery, and since the battery is typically charged while the engine is running, the battery is not subjected to strain. However, when the refrigerator is operated by the car battery while the engine is off, the compressor operates to compress the low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gaseous refrigerant by taking away heat from the surroundings while the liquid refrigerant evaporates in the evaporator through the expansion valve for cooling. This causes the battery to be consumed, and if the refrigerator continues to operate in this manner while the engine is off for a long time, there is a problem that the engine may not start due to the battery being consumed. Therefore, most of the above car refrigerators protect the battery by cutting off the power to the car refrigerator when the engine is turned off. However, in this case, there is a disadvantage that if you stop or park for a certain period of time, the beverages stored in the refrigerator lose their coolness, so you cannot drink a cold beverage when you return to the car after being exposed to the heat. Therefore, recently, auxiliary batteries are being used to enable the refrigerator to operate even after the car's engine is turned off. However, even in this case, when the temperature inside the vehicle rises significantly and the low-temperature, low-pressure gaseous refrigerant installed in the car is compressed into high-temperature, high-pressure gaseous refrigerant and condensed into liquid refrigerant in the condenser, the heat generated is exchanged by a fan. Since the air circulating inside the vehicle is high temperature, the condensation efficiency decreases, which presents a problem in that it may lead to refrigerator malfunction or make it impossible to expect actual cooling efficiency due to the reduced condensation efficiency. FIG. 1 is an embodiment of the state in which the refrigeration system of the present invention is mounted on one side of a refrigerator. FIG. 2 is an embodiment in which the installed refrigeration system of FIG. 1 is combined with a cover. FIG. 3 is an example of the open/closed state of the refrigerator compartment of the present invention. FIG. 4 is a perspective view of the bottom state of the refrigerator of the present invention. FIG. 5 is a combined perspective view showing the ventilation state by a fan in the condenser of the present invention. FIG. 6 is an embodiment for ventilating with outside air while fixing the fan of FIG. 5. Fig. 7 is an exploded view of Fig. 6. FIG. 8 is an example showing the arrangement structure of the compressor and condenser of a typical refrigerator. FIG. 9 is an embodiment of the refrigerator of the present invention in a state coupled to the floor surface of a vehicle. First, the terms used in the specification and claims of the present invention should not be interpreted as being limited to their dictionary meanings. Based on the principle that the inventor may appropriately define the concepts of the terms to best describe their invention, they should be interpreted in a meaning and concept consistent with the technical spirit of the present invention. Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing. The present invention will be described in detail below based on the attached drawings. As illustrated in FIGS. 1 to 9, the configuration of the present invention allows the condenser of the refrigeration system (100) of the refrigerator (10) to circulate with cold outside air while the refrigerator (10) is installed inside a vehicle, thereby improving condensation efficiency and solving the problems of the past. To this end, as shown in FIG. 9, a refrigerator (10) is installed indoors between the driver's seat and the passenger seat such that the lid (21) of the refrigerator compartment can be opened and closed. At this time, the refrigerator (10) is equipped with a refrigerator compartment (20) having a lid (21) that can be opened and closed to store items, and a freezing system (100) is installed on one side of the refrigerator compartment (20). In order to securely mount the above-mentioned freezing system (100) to the refrigerator room (20), as shown in FIG. 1, a storage space (31) is provided on one side of the refrigerator room (20) so as to be open on a surface corresponding to the lid that opens and closes t
