[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] See Figures 1-12 This car refrigerator with ice-making function is installed inside the vehicle's sub-instrument panel. It includes a main body 1 and a compressor 2, condenser 3, universal valve 4, ice-making assembly, and refrigeration assembly mounted on the main body 1. The ice-making assembly includes a first evaporator 5 and an ice bucket 6. The first evaporator 5 is wound around the ice bucket 6. The refrigeration assembly includes at least a second evaporator 7. A storage cavity 8 is provided inside the main body 1. The second evaporator 7 is located on the outer peripheral wall of the storage cavity 8. The compressor 2 is connected to the condenser 3. The condenser 3 can be switched to be connected to the first evaporator 5 and the second evaporator 7 through the universal valve 4. The first evaporator 5 and the second evaporator 7 are respectively connected to the compressor 2. Existing car refrigerators that can be installed inside the vehicle's sub-instrument panel do not have ice-making function. This solution adds ice-making function while meeting the basic cooling and heating functions of a car refrigerator that can be installed inside the vehicle's sub-instrument panel.

[0030] It also includes a dryer filter 29 and a throttling and pressure reducing device installed on the main body 1. The dryer filter 29 is connected to the condenser 3 and the universal valve 4 respectively. The universal valve 4 is connected to the first evaporator 5 and the second evaporator 7 respectively through the corresponding throttling and pressure reducing device.

[0031] The refrigerant is compressed by the compressor 2 and enters the condenser 3. After releasing heat through the condenser 3, it enters the dryer filter 29, then reaches the universal valve 4, and then flows into the first evaporator 5 or the second evaporator 7 after passing through the throttling and pressure reducing device. The refrigerant absorbs heat from the ice bucket 6 or the storage chamber 8, thereby realizing ice making or refrigeration. Then the refrigerant re-enters the compressor 2 to complete the cycle. Ice making cannot be performed when the refrigerator is refrigerating, and refrigeration cannot be performed when ice making is refrigerating.

[0032] The hot gas outlet of compressor 2 is connected to the first evaporator 5 through universal valve 4; the de-icing method after ice making is completed is as follows: compressor 2 directly generates hot gas which is controlled by universal valve 4 to enter the first evaporator 5, thereby increasing the temperature inside ice bucket 6 to melt the surface ice layer and then defrost.

[0033] It also includes a cooling fan 28 and a cooling duct 9 mounted on the main body 1. The condenser 3 is located inside the cooling duct 9. An opening 10 is provided on one side of the cooling duct 9, and the cooling fan 28 is mounted on the opening 10. The cooling duct 9 is connected to the air inlet of the cooling fan 28 through the opening 10, and the air outlet of the cooling fan 28 is connected to the outside (i.e., the outside of the auxiliary instrument panel). The cooling or ice-making speed can be adjusted by adjusting the speed of the compressor 2 to improve the working efficiency and increase the cooling capacity. At the same time, when the vehicle refrigerator is cooling or making ice, the cooling fan 28 will also start when the compressor 2 starts. Together with the cooling duct 9, it improves the heat dissipation efficiency and guides the hot air (heat released by the condenser 3) to be discharged outside the auxiliary instrument panel, avoiding internal backflow and turbulence that would reduce the heat dissipation performance.

[0034] The main body 1 includes a cabinet assembly 11, an ice-making assembly and a refrigeration assembly disposed inside the cabinet assembly 11. The cabinet assembly 11 is filled with a foam layer. The first evaporator 5 and the second evaporator 7 are wrapped in the foam layer and separated from each other by the foam layer. The first evaporator 5 and the second evaporator 7 are mainly isolated from the outside by the cabinet assembly 11 and the foam layer inside the cabinet assembly 11. The top of the first evaporator 5 is covered with a top cover 14 to isolate the outside air, and the top of the second evaporator 7 is covered with a door 15 to isolate the outside air, thereby achieving the heat preservation function and improving the refrigeration or ice-making efficiency.

[0035] The housing assembly 11 includes a housing 30 and a connecting frame 31 covering the top of the housing 30.

[0036] The top of the housing assembly 11 (connecting frame 31) is provided with a first opening 12 and a second opening 13. The first opening 12 corresponds to the ice-making assembly, and the second opening 13 corresponds to the refrigeration assembly. The first opening 12 is covered with a detachable top cover 14, and the second opening 13 is provided with a door 15 that can be rotated to open and close.

[0037] The top cover 14 is provided with a first buckle 32, and the first opening 12 is provided with a second buckle 33. The first buckle 32 and the second buckle 33 are rotated and engaged so that the top cover 14 can be detachably installed on the first opening 12.

[0038] The door body 15 is provided with a rotating hole 34, and the connecting frame 31 is provided with a rotating shaft 35. The rotating shaft 35 is rotatably connected to the rotating hole 34 so that the door body 15 can rotate to open and close on the second opening 13.

[0039] The main body 1 also includes a base frame 16, the bottom of the housing 30 is fixed on the base frame 16, and the compressor 2 and condenser 3 are located outside the housing assembly 11 and fixed on the base frame 16.

[0040] The bottom of the second evaporator 7 is provided with a base support 37, which is used to support the second evaporator 7.

[0041] The first evaporator 5 is a wire tube evaporator, and the second evaporator 7 is a blown evaporator. Cooling is achieved by using the blown evaporator, and ice making is achieved by using the wire tube evaporator. The blown evaporator is the storage part of the refrigerator, and the ice making part is the ice bucket 6. When making ice, the user pours water directly into the ice bucket 6, locks the top cover 14, and then starts making ice.

[0042] A heating component (not shown in the figure) is provided on the side or bottom of the storage cavity 8. The heating component includes at least a heating element, which can heat the storage cavity 8 to achieve the heating function.

[0043] The first evaporator 5 includes a spiral-shaped external heat exchange tube 17 and an internal heat exchange tube 18, which are integrally formed. The external heat exchange tube 17 is connected to the internal heat exchange tube 18. Several ice-making boxes 19 are distributed in a ring inside the ice-making bucket 6. The external heat exchange tube 17 is wrapped around the outside of the ice-making bucket 6, and the internal heat exchange tube 18 is located at the center of the ice-making bucket 6. The internal heat exchange tube 18 is in contact with the inner wall 20 of the ice-making box 19, and the outer wall 21 of the ice-making box 19 is in contact with the inner wall of the ice-making bucket 6. The inner wall 20 faces the inside of the ice-making bucket 6, and the outer wall 21 faces the outside of the ice-making bucket 6. A column 36 is provided at the center of the ice-making bucket 6, and the internal heat exchange tube 18 is coiled on the column 36. The above structure can improve ice-making efficiency and ice quality.

[0044] The external heat exchange tube 17 is provided with a first inlet 22, and the internal heat exchange tube 18 is provided with a first outlet 23. The first inlet 22 is connected to the universal valve 4, and the first outlet 23 is connected to the compressor 2. The refrigerant enters the first evaporator 5 through the first inlet 22, then flows along the external heat exchange tube 17 and continues to the internal heat exchange tube 18, and finally flows out of the first evaporator 5 through the first outlet 23. The ice box 19 exchanges heat through the internal heat exchange tube 18 and the external heat exchange tube 17, so that the water in the ice box 19 turns into ice cubes, thereby achieving efficient ice making. The hot gas generated by the compressor 2 flows through the same path as the refrigerant in the first evaporator 5. The universal valve 4 is equipped with a second inlet 24, a second outlet 25, and a third outlet 26. The second inlet 24 can be switched to connect to the second outlet 25 and the third outlet 26. The condenser 3 is connected to the second inlet 24, the second outlet 25 is connected to the first inlet 22 of the first evaporator 5, and the third outlet 26 is connected to the inlet of the second evaporator 7. The universal valve 4 is a three-way valve. The hot gas outlet of the compressor 2 is connected to the second inlet 24. The universal valve 4 is added to the compressor 2 to realize the use of the hot gas of the compressor 2 to return to the evaporator for de-icing. The shape, size, and quantity of ice cubes can be adjusted by adjusting the ice bucket 6, and there is no need to add a separate drain outlet.

[0045] A lighting assembly 27 is provided on the outer wall of the storage cavity 8. The light-emitting side of the lighting assembly 27 (light lamp 39) faces the storage cavity 8. The lighting assembly 27 includes a mounting bracket 38 and a light lamp 39.
