Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle-mounted refrigerators, in particular to a semiconductor armrest vehicle-mounted refrigerator integrated with an ice maker. BACKGROUND

[0002] With the improvement of the quality of life of automobiles, vehicle-mounted refrigerators have become more and more popular as standard or optional devices for vehicles, especially for the type integrated in the center control armrest box. At present, most of the armrest box vehicle-mounted refrigerators on the market use semiconductor refrigerating fins (TEC) for refrigeration and are cooled by air cooling. Such refrigerators provide users with the convenience of refrigerating beverages, fruits, etc.

[0003] However, most vehicle-mounted refrigerators only provide refrigeration function, which is single in function and cannot meet the upgrading needs of users for instant ice making and separate ice taking. Although some vehicle-mounted refrigerators with ice making function have appeared on the market, they generally adopt the design of independently setting ice making grids in the refrigeration chamber. This structure not only occupies the limited storage volume, but more importantly, since the ice making unit is directly connected with the refrigeration space, the whole box door needs to be opened every time ice is taken, which not only causes a large amount of cold air loss in the refrigerator, increases the working load and energy consumption of TEC, but also causes temperature fluctuation in the box, affecting the preservation effect of other stored goods. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art and provide a vehicle-mounted armrest refrigerator with simple structure, various functions and integrated ice making device.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a semiconductor armrest vehicle-mounted refrigerator integrated with an ice maker, comprising a refrigerator main body, a drawer assembly, an ice making basket, a TEC refrigeration module, a TEC ice making module, a water cooling system and a control module.

[0006] The refrigerator main body is internally provided with a refrigeration cavity, the drawer assembly is slidingly embedded in the refrigeration cavity, the drawer assembly comprises a drawer body and a handle portion integrally formed on the outer end of the drawer body, and the TEC refrigeration module is installed at the bottom of the refrigeration cavity.

[0007] The handle portion is internally provided with an ice making cavity, the TEC ice making module and the ice making basket are arranged in the ice making cavity, and the ice making basket can be pulled out from the outer side of the handle portion.

[0008] The water cooling system is installed in the bottom of the refrigerator main body, and the TEC refrigeration module and the TEC ice making module share one set of water cooling system.

[0009] Furthermore, the control module includes a main control board, a refrigeration temperature sensor, an ice-making temperature sensor, and an operation panel. The main control board is electrically connected to the TEC refrigeration module, the TEC ice-making module, the water-cooling heat dissipation system, the refrigeration temperature sensor, the ice-making temperature sensor, and the operation panel.

[0010] Furthermore, the water-cooled heat dissipation system includes a water-cooling radiator, a cooling fan, and a water tank. The cooling fan is located below the water-cooling radiator for heat dissipation. The water-cooling radiator is connected to the water tank, and a water pump is connected to the water tank for circulating the cooling water.

[0011] Furthermore, the TEC refrigeration module includes a first TEC semiconductor refrigeration chip, a cold-end fin, a cold-end fan, and a first water-cooled plate. The cold-end fin is located above the first TEC semiconductor refrigeration chip and contacts the cold end of the first TEC semiconductor refrigeration chip. The air inlet of the cold-end fan is connected to the refrigeration chamber, and the air outlet is connected to one end of the cold-end fin. An air duct is provided on the bottom plate of the refrigeration chamber. The air duct is located at the end of the cold-end fin away from the cold-end fan. The first water-cooled plate is located below the first TEC semiconductor refrigeration chip and contacts the hot end of the first TEC semiconductor refrigeration chip. The inlet end of the first water-cooled plate is connected to the outlet of the cooling water pump through a conduit.

[0012] Furthermore, the TEC ice-making module includes a second TEC semiconductor refrigeration chip, a molded ice tray, and a second water-cooled plate. The molded ice tray is located below the second TEC semiconductor refrigeration chip and is in contact with the cold end of the second TEC semiconductor refrigeration chip. The molded ice tray extends into the ice-making basket. The second water-cooled plate is located above the second TEC semiconductor refrigeration chip and is in contact with the hot end of the second TEC semiconductor refrigeration chip. The inlet end of the second water-cooled plate is connected to the outlet end of the first water-cooled plate through a conduit, and the outlet end of the second water-cooled plate is connected to the heat dissipation water cooling radiator through a conduit.

[0013] Furthermore, the ice-making cavity is equipped with a lifting device for moving the ice-forming tray up and down and an ice-making trough for supporting the ice-making basket. The side wall of the ice-making trough is equipped with a limiting mechanism for limiting and fixing the ice-forming tray.

[0014] Furthermore, the lifting device includes guide columns disposed on both sides of the ice-making tank, a support plate slidably disposed between the two guide columns, and a lifting handle fixedly disposed on the support plate. The TEC ice-making module is mounted on the support plate, and the lifting handle extends to the outside of the handle portion.

[0015] Furthermore, the limiting mechanism includes an electromagnet and a limit switch, both of which are fixedly connected to the side wall of the ice-making tank.

[0016] The beneficial effects of this invention are:

[0017] This invention integrates the ice-making module into the drawer handle, achieving ice-making functionality without occupying additional space in the refrigerator compartment. This solves the problem of traditional car refrigerators' inability to simultaneously support refrigeration and ice-making functions. The sliding design of the drawer assembly and the pull-out structure of the ice basket ensure that refrigerated storage and ice retrieval operations do not interfere with each other, making it particularly suitable for use in confined spaces within a vehicle.

[0018] The traditional compressor is replaced by a TEC semiconductor refrigeration module, which has no moving mechanical parts, low operating noise, and strong shock resistance, making it suitable for the bumpy environment of vehicle driving; moreover, semiconductor devices consume less power.

[0019] The TEC refrigeration module and ice-making module share a water-cooling system. Through the coordinated work of the water-cooling radiator, water pump and fan, it reduces component redundancy (saving space and cost) and can concentrate and efficiently dissipate heat, avoiding the local overheating problem caused by traditional independent heat dissipation. It is especially suitable for the heat dissipation needs of the closed environment inside the vehicle. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0027] Embodiments of the present invention: such as Figure 1 As shown, a semiconductor armrest car refrigerator with integrated ice maker includes a refrigerator body 1, a drawer assembly 2, an ice-making basket 3, a TEC refrigeration module 4, a TEC ice-making module 5, a water-cooled heat dissipation system 6, and a control module; the refrigerator body 1 has a refrigeration cavity 7 inside, the drawer assembly 2 is slidably embedded in the refrigeration cavity 7, and the shell of the refrigerator body 1 has a built-in heat insulation layer.

[0028] The TEC refrigeration module 4 is located at the bottom of the refrigeration chamber 7. The TEC refrigeration module 4 includes a first TEC semiconductor cooling chip 15, a cold end fin 16, a cold end fan 17, and a first water-cooling plate 18. The cold end of the first TEC semiconductor cooling chip 15 faces upward and the hot end faces downward. The cold end fin 16 is attached to the cold end of the first TEC semiconductor cooling chip 15 with thermally conductive silicone grease. The first water-cooling plate 18 is attached to the hot end of the first TEC semiconductor cooling chip 15 with thermally conductive silicone grease. The cold end fan 17 is located on one side of the cold end fin 16. Its air inlet is connected to the refrigeration chamber 7, and its air outlet is connected to one end of the cold end fin 16. An air duct 19 is provided on the bottom plate of the refrigeration chamber 7. The air duct 19 is located at the end of the cold end fin 16 away from the cold end fan 17. The cold end fan 17 guides the hot air in the refrigeration chamber 7 into the cold end fin 16. When the hot air passes through the cold end fin 16, heat exchange occurs to form cold air. Then, the hot air enters the refrigeration chamber 7 through the air duct 19, forming a circulation.

[0029] The drawer assembly 2 includes a drawer body 8 and a handle portion 9 integrally formed on its outer end. The handle portion 9 is provided with an ice-making cavity 10. The TEC ice-making module 5 and the ice-making basket 3 are both disposed in the ice-making cavity 10, and the ice-making basket 3 can be pulled out from the outer side of the handle portion 9. The TEC ice-making module 5 includes a second TEC semiconductor cooling chip 20, a molded ice tray 21, and a second water-cooling plate 22.

[0030] The bottom of the drawer body 8 has an upward recess, and the soft silicone tube connected to the second water-cooling plate 22 is located in the recess. The outer end of the refrigeration cavity 7 has a limiting block. After the drawer assembly 2 is pulled outward, the side wall of the recess contacts the limiting block to achieve the limiting, thus preventing the drawer body 8 from leaving the refrigeration cavity 7.

[0031] The water-cooled heat dissipation system 6 includes a water-cooling radiator 11, a cooling fan 12, and a water tank 13.

The lifting device includes guide posts 24 on both sides of the ice-making trough 23, a support plate 25 slidably disposed between the two guide posts 24, and a lifting handle 26 fixedly disposed on the support plate 25. The TEC ice-making module 5 is mounted on the support plate 25, and the lifting handle 26 extends to the outside of the handle portion 9. A limiting mechanism is provided on the side wall of the ice-making trough 23 for limiting and fixing the ice-forming tray 21. The limiting mechanism includes an electromagnet 27 and a limit switch 28, both of which are fixedly connected to the side wall of the ice-making trough 23. A magnetic block 29 is provided at the bottom of the support plate, and the electromagnet 27 can attract the magnetic block 29. A return spring 30 is also provided on the guide posts 24 for automatically moving the support plate 25 upward.

[0034] The control module includes a main control board, a refrigerator temperature sensor, an ice-making temperature sensor, and an operation panel. The main control board is electrically connected to the TEC refrigerator module 4, the TEC ice-making module 5, the water-cooled heat dissipation system 6, the refrigerator temperature sensor, the ice-making temperature sensor, and the operation panel. The refrigerator temperature sensor is located inside the refrigerator cavity 7, and the ice-making temperature sensor is installed in the ice-making tray 23. The operation panel is installed on the shell of the refrigerator body 1 (the refrigerator temperature sensor, the ice-making temperature sensor, and the operation panel are not shown in the figure). The electromagnet 27 is connected in series with the limit switch 28 and connected to the main control board. The main control board integrates a timing module, which disconnects the power supply to the electromagnet 27 when the timing time is up.

[0035] Working principle:

[0036] In refrigeration operation, the user sets the refrigeration temperature via the control panel. The main control board activates the first TEC semiconductor cooling chip 15 and the cold-end fan 17. The cold end of the first TEC semiconductor cooling chip 15 generates cooling through the cold-end fins 16. The cold-end fan 17 draws air from the refrigeration chamber 7 and blows it over the cold-end fins 16. The cooled air then flows back to the refrigeration chamber 7 through the air duct 19, forming a circulating cooling system. Simultaneously, the main control board activates the cooling water pump 14 in the water-cooled heat dissipation system 6. The heat generated by the hot end of the first TEC semiconductor cooling chip 15 is transferred to the circulating water through the first water-cooled plate 18, and then dissipated to the outside of the vehicle via the cooling water radiator 11 and the cooling fan 12. The cooling water then flows back into the radiator tank 13, and the cooling water pump 14 drives the water circulation to achieve continuous heat dissipation. When the refrigeration temperature sensor detects that the temperature has reached the set value, the main control board shuts off the first TEC semiconductor cooling chip 15 and enters the heat preservation state. When it is necessary to remove items from the refrigeration chamber 7, the drawer assembly 2 can be opened by grasping the pull handle 26 and pulling it outwards.

[0037] In ice-making, the user injects an appropriate amount of water into the ice basket 3 (the water level does not exceed the height of the ice grid), pushes the ice basket 3 into the ice-making tank 23, starts the ice-making function through the operation panel, and presses down the lifting handle 26. When the support plate 25 moves down along the guide column 24, the return spring 30 is compressed. When the support plate 25 triggers the limit switch 28, the electromagnet 27 attracts the magnetic block 29 to lock it. At this time, the forming ice tray 21 is immersed in the water in the ice basket 3. The main control board starts the second TEC semiconductor cooling chip 20 to start ice making. At the same time, the timing module starts timing. During the ice-making process, the cold end of the second TEC semiconductor cooling chip 20 absorbs heat through the forming ice tray 21 to freeze the water, and the heat from the hot end enters the water cooling system 6 for heat dissipation through the second water cooling plate 22. When the timing time is up, the main control board cuts off the power to the electromagnet 27, the return spring 30 pushes the support plate 25 up, the forming ice tray 21 separates from the ice, and the user can pull out the ice basket 3 to take out the ice.

[0038] Heat dissipation process: The water pump 14 starts and pumps water from the water tank 13 into the first water cooling plate 18, through the conduit into the second water cooling plate 22, and then through another conduit into the water cooling radiator 11 and finally back into the water tank 13. Below the water cooling radiator 11, the cooling fan 12 rotates to carry away the heat.
