The control mainboard is signal-connected to the infrared transmitter, the infrared receiver and the alarm. The milk refrigerator of this scheme outputs cold to the refrigeration chamber through the refrigeration system. Although it can realize the refrigeration of milk, the refrigeration system has a large structure, which not only has a high production cost, but also causes the coffee machine to be too large, which is not conducive to improving the market competitiveness of the coffee machine.

[0033] Based on this, the present application provides a liquid milk refrigeration and preservation device.

[0034] Example 1

[0035] like Figure 1-Figure 4 As shown, this embodiment provides a liquid milk refrigeration and preservation device, comprising:

[0036] A carrier 1, wherein a mounting groove 11 is disposed on the carrier 1, a refrigeration unit 2 is disposed at the bottom of the carrier 1, the refrigeration unit 2 comprises a refrigeration end 21 and a heating end 22, and the carrier 1 is detachably disposed on the refrigeration end 21 of the refrigeration unit 2;

[0037] The heating end 22 of the refrigeration unit 2 is provided with a heat dissipation structure 3 .

[0038] Specifically, the refrigeration unit 2 includes a semiconductor refrigeration plate, and the semiconductor refrigeration plate includes a refrigeration end 21 and a heating end 22 . The refrigeration end 21 is connected to the carrier 1 .

[0039] That is, the refrigeration unit 2 of the present application is implemented by a semiconductor refrigeration chip. The semiconductor refrigeration chip has no mechanical moving parts, so it runs smoothly, reduces mechanical wear and noise, and improves the reliability of the equipment. In addition, the semiconductor refrigeration chip is small in size and light in weight, which is easy to integrate into various devices. It is used to refrigerate items in coffee machines or other electrical appliances, which can streamline the number of equipment and save space. The semiconductor refrigeration chip is driven by direct current and can quickly absorb and release heat at both ends of the thermocouple, thereby achieving a cooling effect. In addition, the cooling and heating time of the semiconductor refrigeration is very fast, and the thermal inertia is small.

[0040] In actual applications, the refrigeration and preservation device also includes a current control device, which is electrically connected to the semiconductor refrigeration chip. By controlling the current input into the semiconductor refrigeration chip, high-precision temperature control can be achieved, which facilitates the formation of a remote control, program control, and automatic control system.

[0041] Specifically, an opening is provided at the top of the mounting groove 11, and the cross-section of the mounting groove 11 is annular, elliptical or polygonal. The mounting groove 11 forms a cylindrical structure, and the opening at the top of the mounting groove is convenient for putting in and taking out liquid milk packages, such as liquid milk tanks. The cross-section of the mounting groove 11 can be designed to be annular, elliptical or polygonal to accommodate liquid milk packages of different shapes and sizes. In a more preferred embodiment, a limiting ring is provided at the opening at the top of the mounting groove 11, and the outer wall of the limiting ring is clamped with the opening, and the inner wall forms a limit for the liquid milk package. Since the limiting ring is clamped, different limiting rings can be replaced as needed to accommodate different shapes of liquid milk packages.

[0042] In the above-mentioned liquid milk refrigeration and preservation device, the carrier 1 is detachably mounted on the refrigeration end 21 of the refrigeration unit 2; the heating end 22 of the refrigeration unit 2 is provided with a heat dissipation structure 3. The refrigeration unit 2 cools the carrier 1, and then cools the liquid milk in the installation groove 11, so as to efficiently and conveniently refrigerate and preserve the liquid milk to prevent the liquid milk from spoiling. Moreover, the refrigeration unit 2 integrates refrigeration and heating and has a compact design, which not only reduces the volume of the entire device and reduces production costs, but also improves the energy efficiency ratio, making the device more energy-saving and environmentally friendly. In addition, the carrier 1 and the refrigeration unit 2 are detachable in design, which is convenient for users to replace and adjust according to actual needs, thereby improving the flexibility and adaptability of the device.

[0043] Furthermore, a cold plate 23 is provided between the refrigeration end 21 and the carrier 1, and a heat-conducting material 24 is provided between the cold plate 23 and the refrigeration end 21. The heat-conducting material 24 is heat-conducting silicone grease.

[0044] Specifically, the cold plate 23 of the present application includes a heat-conducting material 24 and a coating covering the surface of the heat-conducting material 24 . The heat-conducting material 24 may be copper, and the coating may be a ceramic coating. The ceramic coating has excellent wear resistance and scratch resistance, and can increase the service life of the cold plate 23 .

[0045] Furthermore, the outer wall of the carrier 1 is coated with an insulation layer 12, and the insulation layer 12 is coated on the outer wall of the installation groove 11. The insulation layer 12 can be polyurethane foam or polystyrene foam, and the insulation layer 12 is used to reduce the influence of the external environment on the refrigeration effect and improve the refrigeration efficiency.

[0046] In a more specific embodiment, the heat dissipation structure 3 includes a guide structure 31 and a fan 32, the guide structure 31 includes two oppositely arranged first mounting substrates 312 and second mounting substrates 314, the first mounting substrate 312 is connected to the heating end 22 of the refrigeration unit 2;

[0047] A plurality of guide plates 311 are arranged between the two mounting substrates, and the plurality of guide plates 311 are evenly distributed between the two mounting substrates along the circumference of the first mounting substrate 312; two adjacent guide plates 311 are arranged at intervals, and a guide channel 313 is formed between the two adjacent guide plates 311;

[0048] The fan 32 is disposed on one side of the second mounting substrate 314 , and an air outlet communicating with an air inlet end of the fan 32 is disposed on the second mounting substrate 314 .

[0049] When the fan 32 is working, air is sucked in through the air port, so that the outside air passes through the guide channel 313 and the air port and enters the fan 32. Therefore, the airflow can take away the heat generated by the heating end 22 side of the refrigeration unit 2 at the heat dissipation structure 3, thereby achieving the purpose of heat dissipation. Specifically, the fan 32 of the present application can be a cross-flow fan 32.

[0050] In a more preferred embodiment, an exhaust pipe 4 is provided on one side of the fan 32, one end of the exhaust pipe 4 is connected to the air outlet end of the fan 32, and the distance between the air outlet 41 of the exhaust pipe 4 and the center line of the refrigeration unit 2 is greater than 20 cm. The length of the exhaust pipe 4 is greater than 20 cm, so that the hot air can be discharged to a farther place to avoid the hot air from heating the device itself. Specifically, the air outlet 41 of the exhaust pipe 4 and the refrigeration end 21 of the refrigeration unit 2 should be separated into two different chambers to isolate the heat exchange.

[0051] Example 2
