[0002] A vehicle-mounted refrigerator with ice-making function includes a refrigerator body, which includes an ice-making bucket. An evaporator, which can exchange heat with the ice-making bucket, is also provided on the outside of the ice-making bucket. The evaporator is in the shape of a tube and is coiled around the outside of the ice-making bucket. The pipe assembly is connected to the compressor, condenser, and evaporator to form a refrigeration cycle loop. The condenser can deliver refrigerant to the evaporator through the refrigeration cycle loop. The refrigerant absorbs heat from the ice-making bucket, thereby realizing ice making. However, since the evaporator is coiled around the outside of the ice-making bucket, the ice-making effect is not good, such as the ice cubes being hollow or the ice cubes melting rapidly during gas return.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide an ice-making device and vehicle refrigerator that is simple in structure, has good ice-making effect, is stable and reliable, has a good user experience, and is highly practical, so as to overcome the shortcomings of the prior art.

[0005] An ice-making device designed for this purpose includes an ice bucket and an evaporator, characterized in that: the evaporator includes an external heat exchange tube and an internal heat exchange tube that are interconnected; a plurality of ice-making boxes are distributed around the circumference of the ice bucket; the external heat exchange tube is coiled around the outside of the ice bucket; the internal heat exchange tube is located at the center inside the ice bucket and between each ice-making box; and the outer peripheral wall of the ice-making box is in contact with the inner wall of the ice bucket and the internal heat exchange tube, respectively.

The inner heat exchange tube is in contact with the inner wall, and the outer wall is in contact with the inner wall of the ice container.

[0007] The external heat exchange tube is equipped with a refrigerant inlet, and the internal heat exchange tube is equipped with a refrigerant outlet. The refrigerant inlet is located at the beginning of the evaporator, and the refrigerant outlet is located at the end of the evaporator.

[0008] The ice bucket has a central column inside, with internal heat exchange tubes coiled around the column.

[0009] The external heat exchange tube and the internal heat exchange tube are integrally formed and continuously coiled from the first end to the last end of the evaporator. When the evaporator is coiled, the external heat exchange tube and the internal heat exchange tube are coiled in sequence.

[0010] The external heat exchange tube and the internal heat exchange tube are spiral-shaped. The external heat exchange tube is spirally coiled around the outside of the ice bucket, and the internal heat exchange tube is spirally coiled around the column.

[0011] A straight pipe section is provided in the center of the internal heat exchange tube, and a through hole is provided on the column. The straight pipe section extends out of the ice maker after passing through the through hole, and the refrigerant outlet is located at one end of the straight pipe section; the internal heat exchange tube is located between the ice maker and the column.

[0012] The ice bucket has an open-top inner cavity, with the inner heat exchange tube and ice box located on the inner cavity. The ice box has an open-top ice-making chamber that connects to the inner cavity.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-7 This ice-making device includes an ice bucket 1 and an evaporator 2. The evaporator 2 includes an external heat exchange tube 3 and an internal heat exchange tube 4 that are interconnected. The internal heat exchange tube 4 is located inside the external heat exchange tube 3. Several ice boxes 5 are distributed around the inner circumference of the ice bucket 1. The external heat exchange tube 3 is coiled around the outside of the ice bucket 1. The internal heat exchange tube 4 is located at the center inside the ice bucket 1 and between each ice box 5. The outer peripheral wall of the ice box 5 is in contact with the inner wall of the ice bucket 1 and the internal heat exchange tube 4, respectively.

[0025] The ice box 5 is provided with an inner wall 6 and an outer wall 7. The inner wall 6 faces the center of the ice bucket 1, and the outer wall 7 faces the outside of the ice bucket 1. The inner heat exchange tube 4 is in contact with the inner wall 6, and the outer wall 7 is in contact with the inner side wall of the ice bucket 1. The inner wall 6 and the outer wall 7 are the outer walls of the ice box 5. The outer heat exchange tube 3 mainly absorbs the heat of the outer part of the ice box 5 and the ice bucket 1, and the inner heat exchange tube 4 mainly absorbs the heat of the inner part of the ice box 5 and the ice bucket 1, so that the heat of the ice box 5 and the ice bucket 1 can be fully and evenly absorbed by the refrigerant in the evaporator 2.

[0026] The external heat exchange tube 3 is equipped with a refrigerant inlet 8, and the internal heat exchange tube 4 is equipped with a refrigerant outlet 9. The refrigerant inlet 8 is located at the beginning of the evaporator 2, and the refrigerant outlet 9 is located at the end of the evaporator 2. The refrigerant enters the evaporator 2 through the refrigerant inlet 8, then flows along the external heat exchange tube 3 and continues to the internal heat exchange tube 4, and finally flows out of the evaporator 2 through the refrigerant outlet 9. The ice maker 5 exchanges heat through the internal heat exchange tube 4 and the external heat exchange tube 3, so that the water in the ice maker 5 turns into ice cubes, thereby achieving efficient ice making.

[0027] An internal column 10 is provided at the center of the ice bucket 1, and an inner heat exchange tube 4 is coiled around the column 10. The column 10 supports the inner heat exchange tube 4, and the upper part of the inner heat exchange tube 4 extends upward to the top of the column 10. The ice bucket 1 can support the outer heat exchange tube 3, thereby making the evaporator 2 firmly coiled around the ice bucket 1.

[0028] The external heat exchange tube 3 and the internal heat exchange tube 4 are integrally formed to form a heat exchange coil. The evaporator 2 is continuously coiled from the first end to the last end. When the evaporator 2 is coiled, the external heat exchange tube 3 and the internal heat exchange tube 4 are coiled in sequence. That is, the external heat exchange tube 3 is first coiled on the outside of the ice bucket 1, and then the internal heat exchange tube 4 is coiled on the column 10.

[0029] The external heat exchange tube 3 and the internal heat exchange tube 4 are spiral-shaped. The external heat exchange tube 3 is spirally coiled around the outside of the ice bucket 1, and the internal heat exchange tube 4 is spirally coiled around the column 10. The spiral shape of the external heat exchange tube 3 and the internal heat exchange tube 4 can increase the heat exchange stroke and the heat exchange time, thereby improving the ice-making efficiency.

[0030] The inner heat exchange tube 4 has a straight pipe section 11 at its center. The outer side of the column 10 is a hollow structure. The column 10 has a through hole 12. The straight pipe section 11 passes through the through hole 12 and extends out of the ice bucket 1. The refrigerant outlet 9 is located at one end of the straight pipe section 11, so that the refrigerant outlet 9 is located outside the ice bucket 1, which facilitates the connection of the refrigerant outlet 9 to the compressor 16.

[0031] The internal heat exchange tube 4 is located between the ice box 5 and the column 10.

[0032] The ice bucket 1 has an open inner cavity 13. The inner heat exchange tube 4 and the ice box 5 are located on the inner cavity 13. The ice box 5 has an open ice-making chamber 14. The ice-making chamber 14 is connected to the inner cavity 13. Ice blocks are formed on the ice-making chamber 14.

[0033] The ice box 5 is located in the lower part of the inner cavity 13. The bottom of the ice box 5 is provided with a support part 17, and the ice box 5 is supported on the bottom wall of the inner cavity 13 by the support part 17.

[0034] There is a gap 15 between the external heat exchanger tube 3 and the internal heat exchanger tube 4, and the ice box 5 is located on the gap 15.

[0035] This vehicle-mounted refrigerator includes the ice-making device a, a compressor 16, and a condenser 18. The compressor 16 is connected to the condenser 18, the condenser 18 is connected to the refrigerant inlet 8, and the refrigerant outlet 9 is connected to the compressor 16. The refrigerant is compressed by the compressor 16 and enters the condenser 18. After releasing heat through the condenser 18, the refrigerant enters the evaporator 2. When the refrigerant passes through the evaporator 2, it absorbs heat from the ice-making bucket 1, thereby making ice. Then the refrigerant re-enters the compressor 16 to complete the cycle. The process of the refrigerant returning to the compressor 16 in gaseous form after absorbing heat and evaporating in the evaporator 2 is called the gas return process.

[0036] Evaporator 2 is a wire tube evaporator.
