Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted refrigerators, in particular to a vehicle provided with a vehicle-mounted refrigerator. Background Art

[0002] The car refrigerator is one of the optional structures of the vehicle, and its purpose is to enable users to refrigerate or freeze items in the car. The current car refrigerator generally integrates all structures into one, including the box, the storage liner arranged in the box, the evaporator, the condenser, the compressor and other components, and then the entire car refrigerator is installed on the car, and the car is only responsible for supplying power to the car refrigerator. This leads to a more complicated structure of the car refrigerator, and many parts need to occupy a certain space. Therefore, the storage liner of the car refrigerator is generally small and the cost is high. However, the car itself has an air-conditioning system, and the air-conditioning system includes refrigeration components such as the air-conditioning evaporator, the air-conditioning compressor and the air-conditioning condenser. Therefore, in a car equipped with a car refrigerator, it has two completely independent refrigeration circuits. Utility Model Content

[0027] Reference Figure 1 , a vehicle provided with a vehicle refrigerator, comprising a vehicle body, a compressor and a condenser being provided in the vehicle body;

[0028] The vehicle body is provided with a first circuit, on which an air-conditioning evaporator 3 for adjusting the temperature of the vehicle body is provided, and both ends of the first circuit are respectively connected to the compressor and the condenser;

[0029] The vehicle body is provided with a vehicle refrigerator, the vehicle refrigerator comprises a storage cavity and a second circuit, the second circuit is provided with a refrigerator evaporator 4 for condensing the storage cavity, and the two ends of the second circuit are respectively connected to the compressor and the condenser and are connected in parallel with the first circuit;

[0030] The on-off switch is used to control the on-off of the first circuit and the second circuit.

[0031] The vehicle body itself has an air-conditioning compressor 1, an air-conditioning condenser 2 and a first circuit, and the first circuit is provided with an air-conditioning evaporator 3, and the vehicle refrigerator includes a storage cavity and a second circuit, and the second circuit is provided with a refrigerator evaporator 4, and the two ends of the second circuit are respectively connected to the air-conditioning compressor 1 and the air-conditioning condenser 2 of the vehicle body, and the first circuit and the second circuit form a parallel structure. Through this structure, the air-conditioning system of the vehicle and the vehicle refrigerator are combined into one. The vehicle refrigerator is directly connected to the air-conditioning compressor 1 and the air-conditioning condenser 2 of the vehicle itself, so that the structure of the vehicle refrigerator is simpler, with fewer parts, and therefore lower cost. Moreover, since the structure is reduced, the space of the storage cavity can be made larger while the original size remains unchanged, and the user experience is better.

[0032] In this solution, in order to make the refrigerant flowing back into the compressor gas, a gas-liquid separator needs to be provided. In this solution, considering the cost, it is preferred that a first gas-liquid separator 5 is provided in the vehicle body, the first gas-liquid separator 5 is connected to the air-conditioning compressor 1, and the ends of the first circuit and the second circuit are both connected to the first gas-liquid separator 5. In this way, the first circuit and the second circuit can share a first gas-liquid separator 5.

[0033] Preferably, the first gas-liquid separator 5 includes an inlet pipe and an outlet pipe connected to the air-conditioning compressor 1, and the ends of the first circuit and the second circuit are connected to the outlet pipe to form a three-way structure. In other embodiments, the first gas-liquid separator 5 can also be provided with two pipe openings to enter, thereby respectively connecting to the first circuit and the second circuit.

[0034] In other embodiments, a second gas-liquid separator located at the rear end of the first circuit may be provided in the vehicle body; a third gas-liquid separator located at the rear end of the second circuit may be provided in the vehicle refrigerator. This method requires two gas-liquid separators to be provided, so the cost will be higher.

[0035] In order to facilitate the control of the opening of the first circuit and the second circuit, and when the refrigeration system is working, the liquid refrigerant needs to be expanded and gasified before entering the evaporator, so it is preferred to provide a first expansion valve 6 located at the front end of the air conditioner evaporator 3 on the first circuit, and a second expansion valve 7 located at the front end of the refrigerator evaporator 4 on the second circuit; the first expansion valve 6 and the second expansion valve 7 not only play the role of adjusting the expansion degree of the refrigerant, but also play the role of controlling the opening and closing of the first circuit and the second circuit, thereby acting as an opening and closing switch. Of course, in this structure, the opening and closing switch can also be selected as an additional electromagnetic opening and closing valve on the first circuit and the second circuit, so as to control the opening and closing of the first circuit and the second circuit by the electromagnetic opening and closing valve, and the first expansion valve 6 and the second expansion valve 7 are used to control the expansion effect of the refrigerant.

[0036] Under normal circumstances, the power of the vehicle air-conditioning system is much greater than the power of the car refrigerator. Therefore, when the air conditioner and the car refrigerator are working at the same time, the refrigerant pressure entering the air-conditioning evaporator 3 is greater than the refrigerant pressure in the refrigerator evaporator 4. Preferably, the first circuit is provided with a third expansion valve 8 located at the rear end of the air-conditioning evaporator 3, so that the output pressure of the refrigerant is adjusted by the third expansion valve 8, so that the output pressure of the first circuit and the output pressure of the second circuit are similar, thereby avoiding the situation where the excessive refrigerant output pressure of the first circuit compresses the refrigerant flowing out of the second circuit at the confluence point of the first circuit and the second circuit due to excessive output pressure of the first circuit, thereby hindering the normal flow of the refrigerant in the second circuit.

[0037] In this solution, the second circuit is preferably provided with a one-way valve 9 located at the rear end of the refrigerator evaporator 4, so that when the pressure in the first circuit is too high, the second circuit will at most stop flowing without causing backflow.

[0038] In this solution, a fourth expansion valve located at the rear end of the refrigerator evaporator 4 can also be optionally provided on the second circuit, and the refrigerant output pressures of the first circuit and the second circuit can be adjusted approximately through the joint action of the third expansion valve 8 and the fourth expansion valve.

[0039] In this solution, it is preferred that the first circuit is provided with a first pressure sensor 10 located at the rear end of the third expansion valve 8;

[0040] The second circuit is provided with a second pressure sensor 11 located at the rear side of the refrigerator evaporator 4, so that the refrigerant output pressure of the first circuit and the refrigerant output pressure of the second circuit can be measured more accurately, so as to adjust the refrigerant output pressure of the first circuit through the third expansion valve 8.

[0041] In this solution, a third pressure sensor 12 is preferably provided between the third expansion valve 8 and the air-conditioning evaporator 3 , so that the adjustment of the third expansion valve 8 can be more accurately quantified through the measurement data of the first pressure sensor 10 and the third pressure sensor 12 .

[0042] In this solution, a drying filter 13 connected to the rear side of the air-conditioning condenser 2 is preferably provided on the vehicle body, and the front ends of the first circuit and the second circuit are both connected to the drying filter 13 .

[0043] In other embodiments, a main expansion valve may be optionally provided at the rear end of the air-conditioning condenser 2, and the front ends of the first circuit and the second circuit may be connected to the main expansion valve. At the same time, opening and closing solenoid valves may be provided on the first circuit and the second circuit, respectively. In this structure, the refrigerant is gasified and depressurized by the main expansion valve to form a gaseous refrigerant, and then the opening and closing of the first circuit or the second circuit are controlled by the opening and closing solenoid valves to start the corresponding air-conditioning system or vehicle refrigerator system.

[0044] In other embodiments, the on-off switch may also be a three-way regulating valve disposed at the rear end of the drying filter 13, and the ends of the first circuit and the second circuit are both connected to the three-way regulating valve, thereby controlling the on-off of the first circuit or the second circuit through the three-way regulating valve.

[0045] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
