Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a refrigerator. Background Technology

[0002] Currently, most refrigerators on the market require additional heating elements such as heating wires and heating tubes to provide a heat source for the heating device. This results in the direct release of heat generated at the high-temperature end of the semiconductor refrigerator into the environment, leading to the inefficient use of resources and causing waste. Summary of the Invention

[0003] This application provides a refrigerator to solve the technical problem of resource waste in existing refrigerators.

[0004] To address the aforementioned technical problems, this application adopts the following technical solution: A refrigerator includes a cabinet and a heating device. The cabinet includes an appliance compartment and a refrigerator compartment stacked together. The cabinet includes an air duct cover, which covers the top of the cabinet to form the appliance compartment. The air duct cover includes a top cover. The heating device includes a heat insulation plate fixedly connected to or integrally formed with the top cover. The heat insulation plate is a flange of the top cover facing the appliance compartment. The appliance compartment has a refrigeration system, which includes a radiator. One end of the heat insulation plate away from the top cover abuts against the radiator to form a recess with an opening facing away from the appliance compartment. The recess is the heating chamber of the heating device, and the opening is the cavity opening of the heating chamber.

[0005] The radiator includes a first base plate and a second base plate disposed opposite to each other, and the end of the heat insulation plate away from the top cover abuts against the second base plate.

[0006] The second base plate has a receiving surface for receiving heated items.

[0007] The heat insulation plate surrounds the second base plate and is connected between the second base plate and the top cover. The second base plate has a first fixing hole.

[0008] The radiator further includes a plurality of heat dissipation fins fixed to or integrally formed between the first base plate and the second base plate, wherein the first base plate has a second fixing hole that mates with the first fixing hole.

[0009] The heat dissipation fins have clearance channels that cooperate with the first fixing hole and the second fixing hole, as well as heat dissipation channels that connect the air inlet and the air outlet.

[0010] The air duct cover includes side covers disposed opposite to each other on both sides of the electrical compartment, and the side covers have air inlets and air outlets disposed opposite to each other.

[0011] The electrical room also includes a control panel and a fan, with the control panel, the refrigeration system, and the fan arranged sequentially from the air inlet toward the air outlet.

[0012] The refrigeration system further includes a semiconductor cooler and a heat-conducting component. The semiconductor cooler has a high-temperature end that is thermally connected to the first base plate of the heat sink, and a low-temperature end that is thermally connected to the heat-conducting component. The air inlet surface of the fan faces the heat sink.

[0013] The heating device also includes a cover plate, which can be opened and closed to cover the cavity.

[0014] The beneficial effects of this application's embodiments are as follows: This application provides a refrigerator, the cabinet including an air duct cover, the air duct cover being disposed on the top of the cabinet to form an electrical compartment, the air duct cover including a top cover; a heating device including a heat insulation plate fixedly connected to or integrally formed with the top cover, the heat insulation plate being a flange of the top cover facing the electrical compartment; the electrical compartment having a refrigeration system, the refrigeration system including a radiator, the end of the heat insulation plate away from the top cover abutting against the radiator to form an opening facing away from the electrical compartment, the recess being the heating chamber of the heating device, the opening being the cavity opening of the heating chamber, utilizing the principle of a semiconductor refrigerator absorbing heat at one end and releasing heat at the other, using the low-temperature end of the semiconductor refrigerator to cool the refrigerator compartment, and simultaneously using the heat generated at the high-temperature end to heat the object to be heated. This multi-functional design makes the structure more compact, not only saving usable space in the refrigerator but also avoiding resource waste.

[0015] In addition, the radiator has a first base plate and a second base plate arranged opposite to each other. The end of the heat insulation plate away from the top cover abuts against the second base plate. The second base plate has a receiving surface for receiving the object to be heated. The heat insulation plate surrounds the second base plate and is connected between the second base plate and the top cover. The heat insulation plate is the side wall of the heating device, and the second base plate is the bottom wall of the heating device. The second base plate is used to provide heat to the heating chamber, so that the heating chamber is heated. After the user places the object to be heated on the receiving surface, the cover plate is closed on the opening of the heating chamber. The cover plate can press the object to be heated against the second base plate. On the one hand, it makes the surface of the object to be heated as close to the receiving surface as possible to increase the heating area and thus improve the temperature uniformity of the object to be heated. On the other hand, it forms local insulation to prevent the heat of the object to be heated from being lost, accelerates the heating rate of the object to be heated, and improves the heating effect. The heating device has a simple structure and simplifies the assembly process. Attached Figure Description

[0047] Figure 4 This is a cross-sectional structural diagram of the refrigerator provided in this application. The cabinet 500 has multiple receiving cavities. These cavities include an electrical compartment 10, a refrigerator compartment 20, and a collection compartment 30. The electrical compartment 10 houses a refrigeration system 11, a control panel 12, and a fan 13. By all three cavities being located within the electrical compartment 10, electrical connection between the refrigeration system 11 and the fan 13 and the control panel 12 is facilitated, avoiding long-distance wiring and reducing wiring complexity. The refrigerator compartment 20 is used to store items requiring refrigeration.

[0048] Please refer to the following: Figures 5 to 7 , Figure 5This is a side view of the refrigerator body after disassembly provided in this application; Figure 6 This is a three-dimensional structural diagram of a portion of the refrigerator body provided in this application and the disassembled first magnetic component; Figure 7 This is a three-dimensional structural diagram of the first magnetic connector of the refrigerator provided in this application cooperating with a portion of the refrigerator body. The refrigerator body 500 includes an inner liner 21. The inner liner 21 is the inner wall of the refrigerator compartment 20. The inner liner 21 includes a bottom wall 211, a top wall 212, a back wall 213, and side walls 214, wherein the side walls 214 are disposed opposite to each other on both sides of the refrigerator compartment 20. The bottom wall 211 is located on the side of the refrigerator compartment 20 away from the appliance compartment 10, the top wall 212 is located on the side of the refrigerator compartment 20 away from the collection compartment 30, and the side walls 214 are disposed opposite to each other between the bottom wall 211 and the top wall 212. The plane containing the top wall 212 is parallel to the plane containing the bottom wall 211, and the plane containing the back wall 213 and the plane containing the opposite side walls 214 are both perpendicular to the plane containing the bottom wall 211.

[0049] The inner liner 21 is made of polyurethane, acrylonitrile butadiene styrene (ABS), or high-impact polystyrene (HIPS) foaming agents. Polyurethane has a low thermal conductivity and good processing performance. The main raw materials of polyurethane include diphenylmethane diisocyanate, toluene diisocyanate, and polypropylene glycol. Inner liner 21 uses diphenylmethane diisocyanate, toluene diisocyanate, and polypropylene glycol as its main raw materials, and is foamed and molded at high temperatures to ensure that inner liner 21 has optimal thermal conductivity and good insulation performance. Inner liner 21 can also be made of ABS foaming agent. Inner liner 21 made of ABS foaming agent has a smooth surface and exhibits good oil and corrosion resistance, as well as good insulation performance. High-gloss HIPS is made by adding polymer materials to traditional HIPS materials. High-gloss HIPS inner liners have excellent low-temperature resistance and density.

[0050] In some embodiments, the cabinet 500 further includes an air duct cover 41, an inner liner cover 42, and a bottom shell 43. The inner liner cover 42 covers the inner liner 21. The inner liner cover 42 is the outer wall of the refrigerator compartment 20. Foaming material is disposed between the inner liner cover 42 and the inner liner 21, and the foaming material is the insulation layer of the refrigerator compartment 20. The foaming material disposed between the inner liner cover 42 and the inner liner 21 improves the insulation effect and, at the same time, enhances the structural strength to a certain extent. The air duct cover 41 covers the top of the cabinet 500 to form the electrical compartment 10. The air duct cover 41 includes side covers 411, a top cover 412, and a back cover 413. The side covers 411 are disposed opposite to each other on both sides of the electrical compartment 10. The top cover 412 and the back cover 413 are disposed between the side covers 411 on both sides of the electrical compartment 10. The top cover 412 is the top wall of the cabinet 500, and the back cover 413 can be part of the back wall of the cabinet 500. The side covers 411 on both sides of the electrical compartment 10 have opposing air inlets 40a and air outlets 40b. The electrical compartment 10 has an air duct extending from the air inlet 40a to the air outlet 40b. The bottom shell 43 covers the bottom of the housing 500 to form a collection chamber 30. The bottom shell 43 includes side plates 431, which are oppositely disposed on both sides of the bottom shell 43. The side plates 431 have opposing vent holes 43a. The air inside the collection chamber 30 circulates internally and externally with the outside air through the vent holes 43a, thereby preventing the condensate collected in the collection chamber 30 from deteriorating and producing odors, and improving the cleanliness of the collection chamber 30. At the same time, the vent holes 43a of the bottom shell 43 facilitate the evaporation of condensate.

[0051] In some embodiments, the inner liner cover 42 is provided with mounting posts 423. The bottom shell 43 also includes a bottom plate 432 and a back plate 435. The bottom plate 432 is the bottom wall of the housing 500, and the back plate 435 can be part of the back wall of the housing 500. The bottom plate 432 is provided with a fixing cylinder 433 corresponding to the mounting posts 423. The fixing cylinder 433 has blind holes. After the mounting posts 423 are inserted into the blind holes of the fixing cylinder 433, they are fixed by fasteners. The blind holes of the fixing cylinder 433 should have sufficient depth to ensure the stability of the structure after the bottom shell 43 and the inner liner cover 42 are assembled. In addition, the inner liner cover 42 and the bottom shell 43 can also be further fixed by adhesive, bolts or clips. The inner liner cover 42, the air duct cover 41 and the bottom shell 43 can be connected by adhesive, bolts or clips.

[0052] The cabinet 500 also includes a front panel 44. The front panel 44 has a first through-hole 44a and an operation panel 441. The front panel 44 extends from the appliance compartment 10 to the collection compartment 30, that is, from the edge of the top cover 412 of the air duct cover 41 to the edge of the bottom plate 432 of the bottom shell 43. The first through-hole 44a corresponds to the opening of the refrigerator compartment 20. The operation panel 441 corresponds to the appliance compartment 10 and is electrically connected to the control panel 12 located within the appliance compartment 10. The operation panel 441 is located on the side of the front panel 44 facing away from the appliance compartment 10. The position of the operation panel 441 close to the appliance compartment 10 avoids long-distance wiring and reduces wiring difficulty. The operation panel 441 serves as the display and control area of ​​the refrigerator 1000. The operation panel 441 may have an LED display or an LCD display for displaying information such as the temperature inside the refrigerator compartment 20 and the efficiency rating of the refrigerator 1000. The control panel 441 may also have buttons for adjusting the efficiency level of the refrigerator 1000. In some embodiments, the front panel 44 may be fixedly connected to the inner liner 21 or integrally formed.

[0053] A first magnetic attractor 442 is provided on the side of the front panel 44 facing the cabinet 500, circumferentially distributed along the first through hole 44a. That is, the front panel 44 is provided with a first magnetic attractor 442 circumferentially distributed along the inner liner 21. The first magnetic attractor 442 is attached to the front panel 44 and located between the inner liner 21 and the inner liner cover 42. The first magnetic attractor 442 is hidden inside the cabinet 500 and is not visible from the surface of the refrigerator 1000, resulting in a better overall appearance of the refrigerator 1000.

[0054] The cabinet 500 also includes a door 50. The door 50 can be opened and closed to the refrigerator compartment 20. One side of the door 50 is fixed to the inner liner cover 42 by a hinge 52. Therefore, the door 50 can be rotated to open or close the refrigerator compartment 20 via the hinge 52. The hinge 52 has a simple structure and has the advantages of high strength and resistance to loosening or deformation.

[0055] Please refer to the following: Figure 1 The door 50 has a door seal 51 that cooperates with the first magnetic clasp 442. When the door 50 is closed in the refrigerator compartment 20, the door seal 51 is positioned on the side of the door 50 facing the refrigerator compartment 20. The door seal 51 is used to seal the gap between the door 50 and the refrigerator compartment 20 when the door 50 is closed. The surface of the door seal 51 is provided with an anti-stick coating to prevent the door seal 51 from sticking to the edge of the first through hole 44a of the front panel 44 after frost forms. By setting the door seal 51, the cold air inside the refrigerator compartment 20 is prevented from convection with the outside air, thereby avoiding the loss of cold air, reducing energy consumption, and improving the heat preservation performance of the refrigerator 1000. The door seal 51 has a simple structure and is easy to install.

[0056] The door seal 51 is embedded with a second magnetic element (not shown) that cooperates with the first magnetic element 442 of the front panel 44. The first magnetic element 442 and the second magnetic element are used to strengthen the attraction between the edges of the door body 50 and the inner liner 21, and to reduce the stress between the door body 50 and the hinge 52. The first magnetic element 442 is used to attract the second magnetic element to seal the refrigerator compartment 20 by means of magnetic force. When the first magnetic element 442 attracts the second magnetic element, the magnetic attraction generated between the first magnetic element 442 and the second magnetic element will squeeze the gap between the edges of the door seal 51 and the inner liner 21, so that the edges of the door seal 51 and the inner liner 21 are tightly fitted, thereby allowing the door body 50 to seal the refrigerator compartment 20, improving the sealing effect of the door seal 51, thereby blocking the heat exchange between the inside and outside of the refrigerator 1000 and reducing the energy consumption of the refrigerator.

[0057] When the door 50 is closed onto the cabinet 500, the first magnetic member 442 can only engage with the second magnetic member located on the door seal 51 to seal the refrigerator compartment 20. The front panel 44 has no other location with the first magnetic member 442 except along the circumference of the first through hole 44a, and the door 50 has no other location with the second magnetic member except for the door seal 51. This reduces the area covered by the magnetic members and facilitates the expansion of other functions in areas of the front panel 44 where the first magnetic member 442 is not present. For example, an operation panel 441 can be installed on the side of the front panel 44 facing away from the electrical compartment 10.

[0058] The enclosure 500 is made of plastic parts, that is, the inner liner 21, the air duct cover 41, the inner liner cover 42, the bottom shell 43, the front panel 44, and the door 50 are all made of plastic parts, giving people a sense of unity and a sense of design aesthetics.

[0059] Electrical compartment 10 is equipped with a cooling system 11 and a control board 12. The cooling system 11 includes a heat sink 111, a thermoelectric cooler 112, a heat-conducting component 113, and a partition 116. The thermoelectric cooler 112 is electrically connected to the control board 12. The working principle of the thermoelectric cooler 112 is as follows: Utilizing the Peltier effect, a pair of thermocouples composed of N-type and P-type semiconductor materials are used. When a direct current flows through the thermocouples, due to the different directions of the current flow, heat absorption and release phenomena occur at the junction of the thermocouples. This phenomenon is known as the Peltier effect. The thermoelectric cooler 112 is made of N-type and P-type semiconductor materials. When current flows through it, when electrons pass from the P-type semiconductor junction to the N-type semiconductor junction, the junction temperature decreases; when electrons pass from the N-type semiconductor junction to the P-type semiconductor junction, the junction temperature increases. Therefore, one end of the thermoelectric cooler 112 is the low-temperature end, and the other end is the high-temperature end.

[0060] The thermoelectric cooler 112 has a high-temperature end that is thermally connected to the heat sink 111 and a low-temperature end that is thermally connected to the heat-conducting element 113. The low-temperature end is used to absorb heat from the refrigerator compartment 20 to cool it down, while the high-temperature end is used to release the heat absorbed by the low-temperature end to the external environment. Since the high-temperature end is small and has a limited heat dissipation area, it cannot meet the heat dissipation requirements. Therefore, the heat sink 111 is needed to dissipate the heat from the high-temperature end to the external environment. The high-temperature end is thermally connected to the heat sink 111, transferring heat to the heat sink 111 to improve the heat dissipation effect of the high-temperature end of the thermoelectric cooler 112, reduce heat accumulation at the high-temperature end, and improve the cooling effect and service life of the thermoelectric cooler 112. The heat sink 111 has several parallel heat dissipation fins 1112, the plane of which is parallel to the front panel 44, allowing airflow between adjacent heat dissipation fins 1112.

[0061] Since the thermoelectric cooler 112 has a plate-like structure, a heat-conducting structure needs to be connected to its low-temperature end to improve heat absorption. The low-temperature end is thermally connected to a heat-conducting component 113, which serves as the heat-conducting structure for the thermoelectric cooler 112. When the refrigerator 1000 is in operation, the low-temperature end of the thermoelectric cooler 112 exchanges heat with the air inside the refrigerator compartment 20 through the heat-conducting component 113 to absorb heat from the refrigerator compartment 20. By continuously supplying a current to the thermoelectric cooler 112, the internal environment of the refrigerator compartment 20 can be controlled at a lower temperature.

[0062] Thermally conductive materials are provided between the high-temperature end of the semiconductor cooler 112 and the heat sink 111, and between the low-temperature end and the thermally conductive element 113. These materials can be high-thermal-conductivity products such as thermally conductive silicone, thermally conductive grease, or soft silicone thermal pads. The thermally conductive material increases the thermal coupling between the contact surfaces of the high-temperature end and the heat sink 111, and between the low-temperature end and the thermally conductive element 113, thereby more effectively transferring heat from the low-temperature end to the high-temperature end. The thermally conductive element 113 enables the transfer of cold energy to the cold storage compartment 20, and also has a cold storage function. The thermally conductive material is a thermally conductive compound and also an insulator, which can prevent the risk of short circuits. In some embodiments, the thermally conductive element 113 is an aluminum block or a copper block, which combines the advantages of excellent thermal conductivity and light weight.

[0063] The thermoelectric cooler 112 is driven by a DC power supply. The control board 12 converts the 220V AC voltage into 12V, 24V, or 3V-48V DC voltage to power the thermoelectric cooler 112. The thermoelectric cooler 112 determines the high-temperature and low-temperature ends by changing the polarity of the DC current. Using the thermoelectric cooler 112 as the refrigeration device in the refrigerator eliminates the need for refrigerant, aligning with a low-carbon and environmentally friendly lifestyle; it also eliminates mechanical transmission devices, resulting in zero noise; and it boasts high efficiency, low power consumption, and energy savings.

[0064] The partition 116 is a heat-insulating plate with a certain thickness and has a first opening 116a, into which the thermoelectric cooler 112 can be accommodated. When the thermoelectric cooler 112 is accommodated in the first opening 116a, the surface of the thermoelectric cooler 112 is flush with the surface of the partition 116. In some embodiments, the thickness of the thermoelectric cooler 112 and the thickness of the partition 116 may be equal. The partition 116 can separate the heat from the heat sink 111 and the heat conductor 113, preventing heat exchange and heat convection between the heat sink 111 and the heat conductor 113, thereby preventing the temperature of the refrigerator compartment 20 from being affected by the heat sink 111. The side of the partition 116 facing the electrical compartment 10 contacts the radiator 111, while the side of the partition 116 facing away from the electrical compartment 10 contacts the top cover 421 of the inner liner 42. This makes the structure more compact, avoiding excessive occupation of the longitudinal space of the electrical compartment 10. Simultaneously, it prevents the heat-conducting component 113 from contacting the air in the electrical compartment 10, thus achieving a good heat insulation effect. The partition 116 is made of a material with low thermal conductivity, serving to provide structural support and temperature insulation.

[0065] The inner liner cover 42 includes a top cover 421, which has a second opening 421a. The side of the second opening 421a facing the refrigerator compartment 20 has a flange 421b. The flange 421b is fixedly connected to or integrally formed with the top cover 421. The flange 421b can be a cylindrical flange or a square flange, and its size and shape are adapted to the heat-conducting element 113. The heat-conducting element 113 extends through the second opening 421a into the flange 421b. The heat-conducting element 113 should be fully inserted into the flange 421b, such that the surface of the heat-conducting element 113 facing away from the thermoelectric cooler 112 is flush with the end face of the flange 421b. In some embodiments, the inner liner cover 42 also includes a rear cover 422.

[0066] Please see Figure 8 , Figure 8This is a three-dimensional structural schematic diagram of an embodiment of the refrigerator's radiator and refrigeration fan provided in this application. The refrigeration system 11 may further include a radiator 114, which includes radiator fins. The radiator 114 is located on the side of the heat-conducting element 113 away from the thermoelectric cooler 112, and the radiator 114 corresponds to and maintains a thermally conductive connection with the heat-conducting element 113. In some embodiments, the radiator 114 may be disposed in the refrigerator compartment 20, in which case the side of the radiator 114 closest to the electrical compartment 10 is fixed to the top wall 212 of the inner liner. In other embodiments, the radiator 114 may be disposed between the inner liner 21 and the inner liner cover 42. The position of the radiator 114 can be determined according to specific circumstances, as long as the radiator 114 maintains a thermally conductive connection with the heat-conducting element 113. Since the heat-conducting element 113 is located in the flange 421b of the top cover 421, its size is limited. Therefore, a radiator 114 can be installed to improve the cooling effect of the refrigerator compartment 20.

[0067] Since the refrigerator 1000 is a miniature, thin-walled refrigerator, the radiator 114 can be omitted if the cooling effect requirement is not high. In other words, whether or not the radiator 114 is installed depends on the specific situation. If the radiator 114 is not present or is installed in the refrigerator compartment 20, the side of the heat-conducting element 113 away from the semiconductor cooler 112 is thermally connected to the inner liner top wall 212, and a thermally conductive material is provided between the heat-conducting element 113 and the inner liner top wall 212. If the radiator 114 is installed in the refrigerator compartment 20, the radiator 114 and the heat-conducting element 113 are arranged opposite each other on both sides of the inner liner top wall 212 and maintain a thermally conductive connection. In the case where the cooler 114 is located between the inner liner 21 and the inner liner cover 42, the heat-conducting component 113 is directly connected to the cooler 114 through the heat-conducting material. The side of the cooler 114 away from the heat-conducting component 113 is connected to the top wall 212 of the inner liner. Thermally conductive silicone is provided between the heat-conducting component 113 and the cooler 114, as well as between the cooler 114 and the top wall 212 of the inner liner.

[0068] In some embodiments, the refrigeration system 11 may further include a refrigeration fan 115, which may be disposed on one side of the radiator 114. The exhaust port of the refrigeration fan 115 is directed towards the radiator 114, facilitating airflow from the refrigeration fan 115 towards the radiator 114. The refrigeration fan 115 can also indirectly drive the airflow within the refrigerator compartment 20. Specifically, when the refrigerator 1000 is in operation, the blades of the refrigeration fan 115 rotate, and the refrigeration fan 115 blows air towards the radiator 114, increasing the airflow through the radiator 114 and the heat-conducting element 113. This accelerates the transfer of cooling capacity from the radiator 114 to the refrigerator compartment 20, thereby increasing the airflow speed within the refrigerator compartment 20 and improving the cooling effect of the thermoelectric cooler 112 on the refrigerator compartment 20. Therefore, when the refrigeration fan 115 rotates, the air within the refrigerator compartment 20 moves faster, improving the temperature uniformity of the refrigerator compartment 20.

[0069] In some embodiments, the radiator 114 and the refrigeration fan 115 are disposed within the refrigeration compartment 20. The cooling energy generated by the semiconductor cooler 112 is transferred to the radiator 114 via the heat-conducting element 113, and then transferred to the refrigeration compartment 20 by the action of the refrigeration fan 115. Ribs are provided along the edge of the air duct baffle to prevent short circuits in the air duct. Ribs may also be provided between the radiator 114 and the air duct baffle to prevent the radiator 114 and the air duct baffle from sticking together due to condensation, thus preventing the gaps between adjacent fins of the radiator 114 from being blocked by condensed condensation, thereby preventing short circuits and the generation of eddies in the air duct.

[0070] The appliance compartment 10 is located at the top of the cabinet 500, that is, at the upper part of the refrigerator compartment 20, avoiding the placement of electrical components on the back or side of the refrigerator compartment 20, which would occupy space in the refrigerator compartment 20. Without increasing the thickness A and width B of the cabinet 500, the space in thickness A and width B of the refrigerator 1000 can be fully utilized to increase the depth and width of the refrigerator compartment 20, which helps to save floor space.

[0071] The electrical room 10 is also equipped with a fan 13, which is a vertical fan. One or more fans 13 can be used. The fan 13 is electrically connected to the control board 12. The refrigeration system 11 is located between the fan 13 and the control board 12. The fan 13 is installed at the air outlet 40b, with its air inlet facing the radiator 111 and its exhaust facing corresponding to the air outlet 40b. The control board 12 is located on the side of the refrigeration system 11 near the air inlet 40a; that is, the control board 12, the refrigeration system 11, and the fan 13 are arranged sequentially from the air inlet 40a towards the air outlet 40b. The heat from the high-temperature end of the thermoelectric cooler 112 is conducted to the radiator 111, which serves as the heat dissipation medium. The radiator 111 has a larger area than the high-temperature end of the thermoelectric cooler 112, increasing the contact area between the high-temperature air and the heat dissipation medium. Under the suction of the fan 13, outside air flows into the electrical compartment 10 through the air inlet 40a. This air passes through the control board 12, carrying heat from its surface to the radiator 111, and finally exits through the outlet 40b via the flow channels between adjacent heat dissipation fins 1112 of the radiator 111. This lowers the temperature inside the electrical compartment 10, thus ensuring the cooling effect of the semiconductor cooler 112. The air flowing in from the air inlet 40a can also pass through and cool the control board 12, ensuring its safety and stability and extending its service life. Semiconductor cooling technology is closely related to heat dissipation, and the heat dissipation effect largely determines the cooling effect.

[0072] Both the air inlet 40a and the air outlet 40b are equipped with filters on the side closest to the electrical compartment 10. The filters are detachably installed on the air inlet 40a and the air outlet 40b to prevent external impurities from entering the electrical compartment 10 through the air inlet 40a and the air outlet 40b, which could interfere with or damage the electrical components inside the electrical compartment 10. These external impurities include oil fumes, dust, etc.

[0073] During the operation of refrigerator 1000, low-temperature water vapor easily condenses into condensate on the side of the inner liner top wall 212 facing the refrigerator compartment 20. In order to prevent the condensate from dripping into the refrigerator compartment 20, the condensate needs to be collected. In order to prevent the condensate from deteriorating, the condensate needs to be drained.

[0074] A drip tray 22 is provided on the side of the refrigerator compartment 20 near the top wall 212 of the inner liner to collect condensate. The drip tray 22 abuts against the back wall 213 of the inner liner on the side near the back wall 213. The back wall 213 between the drip tray 22 and the top wall 212 has a through hole 213a, the lower edge of which abuts against the base 221 of the drip tray 22. The drip tray 22 covers at least a portion of the top wall 212 of the inner liner. The through hole 213a is the outlet of the drip tray 22. The outlet of the drip tray 22 is located at the lower end of the drip tray 22. In one embodiment, the base 221 of the drip tray 22 is inclined along the central axis of the base 221 in the width B direction of the housing 500 on both sides. Therefore, the central axis of the chassis 221 in the width B direction of the box 500 is the lowest point of the chassis 221, and the through hole 213a on the inner liner back wall 213 corresponds to the central axis of the chassis 221 in the width B direction of the box 500, so as to facilitate the introduction of condensate in the water receiving tray 22 into the through hole 213a and improve the speed of condensate drainage.

[0075] The bottom shell 43 has a water collection trough 434, which is located on the side of the bottom shell 43 away from the front panel 44. A drainage pipe 60 is located within the foamed material between the inner liner back wall 213 and the rear cover 422. One end of the drainage pipe 60 is connected to the through hole 213a via a fastener and communicates with the drip tray 22; the other end extends towards the water collection trough 434. The bottom shell 43 covers the bottom of the cabinet 500, forming a collection chamber 30. The collection chamber 30 is located below the refrigerator compartment 20. The drainage pipe 60 is located between the inner liner 21 and the inner liner cover 42 of the refrigerator compartment 20. Therefore, an opening needs to be provided at the bottom of the inner liner cover 42 to facilitate extending the drainage pipe 60 to the water collection trough 434 to collect condensate water uniformly into the water collection trough 434.

[0076] During the operation of the refrigerator 1000, condensation will form on the side of the inner liner 21 facing the refrigerator compartment 20. The condensation from the inner liner back wall 213 and the opposing side walls 214 of the inner liner 21 will flow along the walls to the bottom wall 211. Therefore, a drain outlet is provided on the bottom wall 211, and the drain pipe 60 has a branch pipe 61 fixedly connected to the drain outlet on the bottom wall 211. The condensation collected on the bottom wall 211 flows out of the drain outlet and then along the branch pipe 61 to the water collection tank 434. The collection chamber 30 is mainly used to collect the condensation generated during the operation of the refrigerator 1000, and the vent 43a on the bottom shell 43 facilitates the evaporation of the condensation.

[0077] The refrigerator compartment 20 has a shelf 23, which may include dividers 231 and / or shelves 232. Dividers 231 are disposed between opposing inner liner sidewalls 214, with the plane of the dividers 231 parallel to the inner liner sidewalls 214. The inner liner sidewalls 214 have first guide rails 214a, and the dividers 231 have second guide rails 231a opposite to the first guide rails 214a. Shelves 232 are detachably mounted on the first guide rails 214a and the second guide rails 231a. Furthermore, the shelf 23 also includes a drawer, which is located on the side of the refrigerator compartment 20 near the bottom wall 211 of the inner liner. The arrangement of dividers 231, shelves 232, and drawers facilitates the classification of refrigerated items.

[0078] In some embodiments, the refrigerator 1000 includes, but is not limited to, a cosmetic refrigerator, a kitchen condiment refrigerator, a car refrigerator, an ice bar, or a medicine refrigerator. The refrigerator 1000 can be a wall-mounted refrigerator, a stacked refrigerator, or a stand-up refrigerator.

[0079] In some embodiments, the inner liner 21 may include a direct cooling plate 25 and an inner liner wall 26. The direct cooling plate 25 is a heat-dissipating aluminum plate, which has good thermal conductivity and bending resistance, and is not prone to rust. Please refer to [link / reference]. Figure 9 , Figure 10 , Figure 9 This is a three-dimensional structural schematic diagram of an embodiment of the direct cooling plate of the refrigerator provided in this application; Figure 10 This is a partial structural diagram of the refrigerator's cooling plate and inner liner wall as provided in this application. Please refer to it as well. Figure 6 , Figure 7 The direct cooling plate 25 includes a first drainage section 251, a guide section 253, and a second drainage section 252 connected in sequence. The first drainage section 251 is disposed along the top wall of the refrigerator compartment 20. The second drainage section 252 is disposed along the back wall of the refrigerator compartment 20. The first drainage section 251 is part of the inner liner top wall 212. The second drainage section 252 is part of the inner liner back wall 213. The inner liner wall 26 includes a first panel 261, a second panel 262, a first extension section 263, and a second extension section 264. The first panel 261 is disposed opposite to each other on both sides of the refrigerator compartment 20. The first panel 261 is the inner liner side wall 214. The second panel 262 is the inner liner bottom wall 211. The first extension section 263 is another part of the inner liner top wall 212. The second extension section 264 is another part of the inner liner back wall 213.

[0080] In some embodiments, the inner liner wall 26 is fixedly connected to or integrally formed with the front panel 44. The front panel 44 and first panels 261 disposed opposite each other on both sides of the refrigerator compartment 20 surround a first extension 263. The first extension 263 has a first notch (not shown) on the side opposite to the front panel 44 and is at least partially connected to the second extension 264. A second panel 262 and the first panels 261 disposed opposite each other on both sides of the refrigerator compartment 20 surround a second extension 264. The second extension 264 has a second notch (not shown) on the side opposite to the second panel 262 that mates with the first notch, wherein the first and second notches communicate. A direct cooling plate 25 mates with the inner liner wall 26 to fill the gaps between the first and second notches.

[0081] The direct cooling plate 25 is at least partially overlapped with the inner liner wall 26 on the side facing away from the refrigerator compartment 20. The first drainage section 251 at least partially overlaps with the first extension section 263, and the second drainage section 252 at least partially overlaps with the second extension section 264. The portion of the inner liner wall 26 that overlaps with the direct cooling plate 25 is an overlap edge 24, the width (E) of which is greater than or equal to 5 mm and less than or equal to 40 mm, improving the structural strength and sealing of the inner liner 21. In some embodiments, the width E of the overlap edge 24 can be 5 mm, 10 mm, 15 mm, 20 mm, 22.5 mm, 27.5 mm, 30 mm, 33.5 mm, 35 mm, 38.5 mm, or 40 mm. A guide section 253 connects between the first drainage section 251 and the second drainage section 252. The surface of the guide section 253 facing the refrigerator compartment 20 is an arc surface, which is an arc surface that protrudes away from the refrigerator compartment 20. That is, the guide section 253 has a rounded edge structure, which not only helps to reduce stress concentration, but also helps the cooling airflow to flow towards the second guide section 252.

[0082] The first drainage portion 251, the guide portion 253, and the second drainage portion 252 are fixedly connected or integrally formed. When the first drainage portion 251, the guide portion 253, and the second drainage portion 252 are fixedly connected, it is necessary to ensure that the materials of the first drainage portion 251, the guide portion 253, and the second drainage portion 252 are the same to ensure the stability of the structure. There are no special restrictions on the connection method of the first drainage portion 251, the guide portion 253, and the second drainage portion 252, as long as the surface of the connection between the first drainage portion 251, the guide portion 253, and the second drainage portion 252 is smooth and burr-free.

[0083] The thickness of the direct cooling plate 25 is 1.5-4mm. Specifically, the thickness of the direct cooling plate 25 can be 1.5mm, 1.75mm, 2.0mm, 2.25mm, 2.5mm, 2.75mm, 3mm, 3.5mm, or 4mm. The relatively thin thickness of the direct cooling plate 25 improves the space utilization of the refrigerator compartment 20 and reduces the weight of the refrigerator 1000 to some extent. The direct cooling plate 25 can not only serve as part of the inner liner 21, but also as a direct cooling structure within the refrigerator compartment 20, achieving heat exchange within the refrigerator compartment 20, thus saving internal space with its multi-functional design.

[0084] The first drainage section 251 can be part of the inner liner top wall 212, and the second drainage section 252 can be part of the inner liner back wall 213. The direct cooling plate 25 surrounds the refrigerator compartment 20 on both sides, thus expanding the cooling area.

[0085] In some embodiments, the first drain portion 251 has a locking hole 251a. The locking hole 251a corresponds to the flange 421b of the top cover 421 of the inner liner 42. The heat-conducting element 113 extends through the second opening 421a into the flange 421b, and the surface of the heat-conducting element 113 facing away from the thermoelectric cooler 112 is flush with the end face of the flange 421b. The locking hole 251a is used to fix the heat-conducting element 113 to the first drain portion 251 by cooperating with a fastener. The first drain portion 251 and the heat-conducting element 113 are thermally connected, and a thermally conductive material is disposed between the first drain portion 251 and the heat-conducting element 113, that is, the refrigeration system is located at the top of the refrigerator compartment 20.

[0086] Because air density varies with temperature, it increases as temperature decreases. The refrigeration system 11 is located at the top of the refrigerator compartment 20, generating cooling airflow at the top. Specifically, cooling airflow is generated on the side of the first intake section 251 facing the refrigerator compartment 20. This cooling airflow flows from the first intake section 251 to the guide section 253, then along the guide section 253 to the second intake section 252, and descends along the wall of the second intake section 252 to the second panel 262. During its descent, at least part of the cooling airflow diffuses into the refrigerator compartment 20. After descending to the second panel 262, the cold air also diffuses upwards, resulting in a uniform temperature distribution within the refrigerator compartment 20. Additionally, at least part of the cooling airflow, due to its own density and gravity, forms natural convection within the refrigerator compartment 20. Under the combined effects of natural convection and the direct cooling plate 25, the cooling airflow circulates within the refrigerator compartment 20, achieving efficient cooling and good vibration damping and noise reduction, effectively improving the comfort of using the refrigerator.

[0087] The direct cooling plate 25 can solve the problem that the refrigeration fan 115 aims to solve and achieve the same effect. Therefore, the direct cooling plate 25 can replace the refrigeration fan 115. In other words, when the inner liner 21 has the direct cooling plate 25 structure, the refrigeration fan 115 can be eliminated. This not only improves the space utilization of the refrigerator 1000 but also reduces the structural weight and, to some extent, eliminates the noise impact. Furthermore, using the direct cooling plate 25 to replace the refrigeration fan 115 can reduce power consumption and save energy.

[0088] The inner wall 26 is made of polyurethane, ABS, or high-gloss HIPS foaming agents. The direct cooling plate 25 is made of aluminum, which has advantages such as good thermal conductivity and good cooling effect, allowing the temperature inside the refrigerator compartment 20 to drop rapidly in a short time. In some embodiments, the direct cooling plate 25 may be made of other materials with good conductivity. In some embodiments, both the inner wall 26 and the direct cooling plate 25 may be made of aluminum.

[0089] A drip tray 22 is provided on the side of the refrigerator compartment 20 near the first drainage section 251. The drip tray 22 includes a base 221, and the side of the base 221 near the second drainage section 252 abuts against the second drainage section 252. The second drainage section 252, located between the base 221 and the first drainage section 251, has a through hole 213a. The lower edge of the through hole 213a abuts against the base 221. The drip tray 22 at least partially covers the first drainage section 251. A drainage pipe 60 is provided between the inner liner back wall 213 and the rear cover 422. One end of the drainage pipe 60 is connected to the through hole 213a by a fastener, and the other end extends into the water collection tank 434, thereby realizing the collection of condensate.

[0090] Please see Figure 11 , Figure 11This is a schematic diagram illustrating the assembly process of a portion of the refrigerator's body structure provided in this application. The front panel 44, inner liner cover 42, and inner liner wall 26 are fixedly connected or integrally formed. During assembly with the direct cooling plate 25, the combined or integral structure of the front panel 44, inner liner cover 42, and inner liner wall 26 forms a foaming cavity. Under the support of the foaming mold 45, foaming agent is injected into the foaming cavity, forming an insulation layer within it. The foaming mold 45 presses down on the foaming cavity to prevent deformation. To better prevent the foaming agent from overflowing from the contact point between the direct cooling plate 25 and the inner liner wall 26, the side of the direct cooling plate 25 facing away from the refrigerator compartment 20 is at least partially overlapped with the inner liner wall 26. The first extension 263 at least partially overlaps with the first drainage section 251, and the second extension 264 at least partially overlaps with the second drainage section 252. The overlapping portion between the inner liner wall 26 and the direct cooling plate 25 is the overlap edge 24, the width E of which is greater than or equal to 5 mm and less than or equal to 40 mm. This prevents the direct cooling plate 25 from separating from the inner liner wall 26, improves the structural strength and sealing of the inner liner 21, and also prevents the foaming agent from overflowing, thus improving the assembly effect. Since the foaming agent has adhesive properties after foaming, the combined structure or integrated structure of the front panel 44, the inner liner cover 42, and the inner liner wall 26 can be bonded to the direct cooling plate 25 with the foaming agent to form an integral whole. Therefore, it is not necessary to connect the direct cooling plate 25 and the inner liner wall 26 with other fasteners or connectors. The front panel 44, inner liner cover 42 and inner liner wall 26 are combined or integrated to form a foaming cavity with the direct cooling plate 25. Then, foaming agent is injected after being supported by foaming mold 45 to form an integral unit. The assembly process is simple, the foaming agent has good adhesion properties, and the sealing effect of the cold storage compartment 20 is improved.

[0091] The guide section 253 has a rounded edge structure. After the front panel 44, inner liner cover 42 and inner liner wall 26 are assembled with the direct cooling plate 25, the guide section 253 and the inner liner wall 26 can be connected by filling with foaming agent, thereby ensuring the sealing of the inner liner 21.

[0092] In some embodiments, the vertically placed fan 13 can be replaced with a horizontally placed cooling fan 14. See also... Figures 12-14 , Figure 12 This is an exploded structural diagram of the cooling fan and some parts of the refrigerator provided in this application; Figure 13 This is a three-dimensional structural schematic diagram of an embodiment of the air duct cover of the refrigerator with a heat dissipation fan provided in this application; Figure 14This is a cross-sectional structural diagram of the refrigerator with a cooling fan provided in this application. The air duct cover 41 may include a side cover 411 and a top cover 412. The side covers 411 are disposed opposite each other on both sides of the appliance compartment 10. The side covers 411 may have a first air inlet 411a and a second air inlet 411b disposed opposite each other. The top cover 412 is the top wall of the cabinet 500. The top cover 412 may have an air outlet 412a. The first air inlet 411a and the second air inlet 411b are located on both sides of the air outlet 412a. The air duct cover 41 also includes a fan cover 414. The fan cover 414 surrounds the air outlet 412a to form a barrier facing the appliance compartment 10.

[0093] The cooling fan 14 is adapted to the baffle wall and is installed within the space surrounding the baffle wall. The fan shroud 414 axially wraps around the cooling fan 14, which can suppress the generation of eddies, reduce the suction and exhaust resistance of the cooling fan 14, and reduce airflow noise. The size, shape, and depth of the baffle wall are adapted to the cooling fan 14, making the structure more compact and saving internal space. When the cooling fan 14 is installed in the baffle wall, the side of the cooling fan 14 facing the electrical room 10, that is, the air inlet surface of the cooling fan 14 can be flush with the end face of the fan shroud 414 or protrude appropriately, so as to better exert the suction effect of the cooling fan 14 and thus ensure the airflow entering the electrical room 10.

[0094] The fan cover 414 is fixedly connected to or integrally formed with the duct cover 41. The fan cover 414 and the duct cover 41 can be an integral structure, preventing the fan cover 414 from detaching from the duct cover 41 due to the continuous rotation of the cooling fan 14, thus enhancing structural strength. The fan cover 414 and the duct cover 41 can also be fixedly connected to form an integral unit. Fixed connection methods include, but are not limited to, riveting, welding, gluing, bolting, keying, snap-fitting, and magnetic adsorption. The cooling fan 14 can be directly installed on the fan cover 414 using fasteners, simplifying the assembly process and facilitating later cleaning or maintenance. Fasteners include, but are not limited to, bolts or snap-fit ​​components.

[0095] A control panel 12 is disposed between the first air inlet 411a and the air outlet 412a. A refrigeration system 11 is disposed between the control panel 12 and the second air inlet 411b. The refrigeration system 11 includes a heat-conducting component 113, a semiconductor refrigerator 112, and a radiator 111 arranged sequentially from the refrigerator compartment 20 toward the air outlet 412a. The air inlet surface of the cooling fan 14 faces the radiator 111, and the air outlet surface of the cooling fan 14 corresponds to the air outlet 412a. In other embodiments, corresponding electrical components may also be disposed at the second air inlet 411b and the air outlet 412a. When the cooling fan 14 rotates, it drives outside air to enter through the first air inlet 411a and the second air inlet 411b, which are arranged opposite each other on both sides of the electrical compartment 10. The air flowing in from the first air inlet 411a flows through the control board 12 and carries the heat of the control board 12 to the radiator 111. The air flowing in from the second air inlet 411b flows through the electrical components (not shown) between the second air inlet 411b and the air outlet 412a and carries the heat of the electrical components to the radiator 111. The air inlet surface of the cooling fan 14 can quickly absorb the heat of the radiator 111. The exhaust surface of the cooling fan 14 corresponds to the air outlet 412a to exhaust the heat from the air outlet 412a to the outside environment, thereby accelerating the heat dissipation efficiency and improving the overall cooling efficiency of the refrigeration system 11.

[0096] The electrical compartment 10 receives air from the first air inlet 411a and the second air inlet 411b, which are positioned opposite each other, ensuring sufficient airflow into the electrical compartment 10. After cooling the electrical components, the cold air becomes hot air through heat transfer. Because hot air has a lower density and pressure than cold air, it rises and exits through the top air outlet 412a, facilitating self-heating convection and improving airflow efficiency. This enhances the heat dissipation effect of the refrigerator 1000, and consequently improves the cooling effect of the semiconductor cooler 112. The exhaust outlet 412a of the cooling fan 14 corresponds to this. The electrical compartment 10 has air intake on both sides and air outlet on one side. When the cooling fan 14 rotates, the airflow direction from the first air inlet 411a to the radiator 111 and from the second air inlet 411b to the radiator 111 is approximately perpendicular to the airflow direction from the radiator 111 to the air intake surface of the cooling fan 14.

[0097] The heat sink 111 includes a first base plate 1111 and a plurality of heat dissipation fins 1112 fixed to or integrally formed on the first base plate 1111. The first base plate 1111 is thermally connected to the thermoelectric cooler 112, and the heat dissipation fins 1112 are located on the side of the heat sink 111 facing the cooling fan 14. The plane of the heat dissipation fins 1112 is perpendicular to the plane of the first base plate 1111, that is, the plane of the heat dissipation fins 1112 is parallel to the front panel 44. Adjacent heat dissipation fins 1112 are spaced apart by a certain distance, so that a heat dissipation channel 1112a is formed between adjacent heat dissipation fins 1112, connecting the first air inlet 411a, the second air inlet 411b, and the air outlet 412a. Outside air flows into the appliance compartment 10 from both sides of the refrigerator 1000 in the width B direction. The air inlet of the cooling fan 14 corresponds to the heat dissipation channel 1112a of the heat dissipation fins 1112, and the exhaust port of the cooling fan 14 corresponds to the air outlet 412a. This gives the appliance compartment 10 an air duct extending from the first air inlet 411a to the air outlet 412a and from the second air inlet 411b to the air outlet 412a. This ensures that the air circulates evenly in the appliance compartment 10, and improves the heat dissipation effect while ensuring air uniformity.

[0098] In some embodiments, the edges of the heat dissipation fins 1112 may be flush with the edges of the first base plate 1111, and may be fixed at equal intervals, spaced apart, or integrally formed on the first base plate 1111. The uniform arrangement of the heat dissipation fins 1112 can maintain the stability of the heat sink 111 structure and the uniformity of heat dissipation.

[0099] Please refer to the following: Figure 15 , Figure 15This is a three-dimensional structural schematic diagram of an embodiment of the refrigerator cooling fan provided in this application. The side of the radiator 111 that contacts the high-temperature end of the semiconductor cooler 112 is the first base plate 1111. The cooling fan 14 and the first base plate 1111 of the radiator 111 have mutually mating fixing holes. The cooling fan 14 and the radiator 111 are connected by fixing components that mate with the fixing holes. The first base plate 1111 of the radiator 111 and the partition 116 have mutually mating fixing holes. The radiator 111 and the partition 116 are fixedly connected by fixing components that mate with the fixing holes. The heat-conducting component 113 and the partition 116 have mutually mating fixing holes. The heat-conducting component 113 and the partition 116 are fixedly connected by fixing components that mate with the fixing holes. Thus, the cooling fan 14, the radiator 111, the partition 116, the heat-conducting component 113 and the thermoelectric cooler 112 are connected to form a whole. The thermoelectric cooler 112 cannot have fixing holes and is sandwiched between the radiator 111 and the heat-conducting component 113. The heat-conducting component 113 and the inner liner top wall 212 are provided with mutually matching fixing holes. The fixing component is matched with the fixing hole to connect the heat-conducting component 113 and the inner liner top wall 212. The heat-conducting component 113 and the inner liner top wall 212 are in full contact, which facilitates the transfer of the cold energy of the heat-conducting component 113 to the refrigerator compartment 20 through the inner liner top wall 212.

[0100] The center of the air outlet 412a coincides with the axis of rotation of the cooling fan 14 to ensure the exhaust effect of the cooling fan 14. A first dust filter 415 is provided on the side of the cooling fan 14 facing the air outlet 412a to prevent external impurities from falling onto the cooling fan 14 through the air outlet 412a, affecting the rotation speed of the cooling fan 14, thereby reducing the heat dissipation effect of the refrigerator 1000 and affecting the cooling effect of the semiconductor refrigerator 112. A second dust filter (not shown) can be provided on the side of the first air inlet 411a and the second air inlet 411b facing the electrical compartment 10 to prevent external impurities from falling into the electrical compartment 10 and affecting the electrical components inside the electrical compartment 10. The second dust filter installed at the first air inlet 411a and the second air inlet 411b, and the first dust filter 415 installed at the air outlet 412a, can be detachable. That is, the dust filter can be fixed to the first air inlet 411a, the second air inlet 411b, and the air outlet 412a using clips or screws, facilitating later cleaning or replacement. In particular, the dust filter 415 installed at the air outlet 412a needs to be cleaned frequently to prevent short circuits in the air duct due to blockage.

[0101] The cooling fan 14 is horizontally positioned above the radiator 111, maximizing the coverage of the radiator 111. This allows air to flow quickly and evenly throughout the radiator 111, preventing short circuits and eddies in the airflow. It also increases the uniformity of the high-temperature air flowing through the radiator 111, ensuring full utilization of the radiator 111 and improving the heat exchange efficiency between the radiator 111 and the air. This, in turn, enhances the cooling effect of the refrigerator 1000 and, consequently, the cooling effect of the semiconductor refrigerator 112. Simultaneously, it allows the high-temperature air in the appliance compartment 10 to be quickly discharged from the air outlet 412a through the gaps between adjacent cooling fins 1112, increasing the airflow speed and further improving the cooling efficiency of the refrigerator 1000.

[0102] In some embodiments, both the radiator 111 and the cooling fan 14 are flat square structures. By increasing the floor area of ​​the radiator 111 and the cooling fan 14 to reduce the thickness, the cooling fan 14 is stacked on the upper surface of the radiator 111 while keeping the height C of the refrigerator 1000 unchanged. This results in a compact structure, saves internal space in the appliance compartment 10, avoids the refrigerator 1000 from being too tall, and thus reduces the volume of the refrigerator 1000.

[0103] The cooling fan 14 has fan blades 141 with a diameter of 100mm-150mm. The cooling fan 14 operates at a speed of 200-1500 r / min. By increasing the diameter of the fan blades 141, the operating speed of the cooling fan 14 is reduced, thereby reducing noise while maintaining the suction effect. The suction effect of the cooling fan 14 is directly proportional to the diameter of the fan blades 141 and the operating speed of the cooling fan 14. The noise generated by the cooling fan 14 is also directly proportional to the operating speed; that is, the faster the speed, the louder the noise. To maintain the suction effect, a larger diameter of the fan blades 141 requires a lower operating speed, resulting in less noise.

[0104] In some embodiments, the number of fan blades 141 should be set to an odd number. If the number of fan blades 141 is even, resonance is easily caused due to symmetry. When one fan blade 141 vibrates, it causes the other fan blade 141 to vibrate as well, making it difficult to adjust the balance of the fan blades 141 and thus increasing the noise. If the number of fan blades 141 is odd, although there will be vibration, it will not cause resonance, thus ensuring the balance of the fan blades 141 during operation and reducing the noise. Therefore, the number of fan blades 141 should be set to an odd number, such as 3, 5 or 7.

[0105] The plane containing the edge of the fan shroud 414 is perpendicular to the plane containing the top cover 412. The cooling fan 14 is disposed within the space formed by the fan shroud 414 and the top cover 412. That is, the fan shroud 414 covers the cooling fan 14, and the purpose of the fan shroud 414 surrounding the cooling fan 14 is to prevent short circuits in the air duct and the generation of eddies. The characteristic of air flow is that it avoids the path with high resistance and tends to flow towards the path with low resistance. If the fan shroud 414 is not provided, some of the air flowing in from the first air inlet 411a and the second air inlet 411b will not pass through the radiator 111 and will flow directly to the cooling fan 14 and be discharged from the air outlet 412a, resulting in a reduction in the heat exchange effect of the radiator 111. The distance between the fan cover 414 and the cooling fan 14 is S1, where S1 is greater than or equal to 1 mm and less than or equal to 5 mm. In some embodiments, the distance between the fan cover 414 and the cooling fan 14 can be 1 mm, 1.5 mm, 1.85 mm, 2.35 mm, 2.75 mm, 3.8 mm, 4.6 mm, or 5 mm. The distance between the cooling fan 14 and the radiator 111 is S2, where S2 is greater than or equal to 1 mm and less than or equal to 5 mm. In some embodiments, the distance between the cooling fan 14 and the radiator 111 can be 1 mm, 1.35 mm, 2.25 mm, 2.75 mm, 3.5 mm, 4.35 mm, 4.8 mm, or 5 mm. This arrangement not only facilitates installation but also minimizes the risk of short circuits and eddy currents in the air duct.

[0106] Please see Figures 16 to 19 , Figure 16 This is an exploded structural diagram of the heating device of the refrigerator provided in this application; Figure 17 This is a schematic diagram of the disassembled structure of the refrigerator with heating device provided in this application; Figure 18 This is a cross-sectional structural diagram of the refrigerator with a heating device provided in this application; Figure 19 This is a three-dimensional structural schematic diagram of one embodiment of the refrigerator radiator provided in this application. When the refrigerator 1000 is used as a refrigerator for refrigerating items 90 to be heated, the refrigerator compartment 20 provides protection for the shelf life of the items 90. However, some items 90 require heating before use to achieve better skincare effects. For such items 90, users usually use them after heating. These items 90 include, but are not limited to, face masks. Utilizing the principle that one end of the semiconductor cooler 112 absorbs heat and the other end releases heat, the low-temperature end of the semiconductor cooler 112 cools the refrigerator compartment 20, while simultaneously using the heat generated at the high-temperature end to heat the items 90. This multi-functional design makes the structure more compact, saving usable space in the refrigerator 1000 and avoiding resource waste.

[0107] In some embodiments, the refrigerator 1000 further includes a heating device 70. The air duct cover 41 includes a top cover 412. The heating device 70 includes a cover plate 71 and a heat insulation plate 72 that is fixedly connected to or integrally formed with the top cover 412. The heat insulation plate 72 is a flange of the top cover 412 facing the appliance compartment 10. The fixed connection method includes, but is not limited to, riveting, welding, bonding, magnetic adsorption, etc., as long as the surface of the connection between the heat insulation plate 72 and the top cover 412 is smooth and burr-free and maintains a sealed connection after the fixed connection.

[0108] The radiator 111 includes a first base plate 1111 and a second base plate 1113 disposed opposite to each other. The end of the heat insulation plate 72 away from the top cover 412 abuts against the second base plate 1113 to form a recess with an opening facing away from the electrical compartment 10. The recess is the heating chamber 70b of the heating device 70, and the opening is the cavity opening 70a of the heating chamber 70b. A cover plate 71 can be opened and closed to cover the cavity opening 70a. After placing the object to be heated 90 in the heating chamber 70b and closing the cover plate 71 to the cavity opening 70a, the heating mode can be activated by adjusting the operation panel 441 to heat the object 90. The specific shape and size of the heating chamber 70b can be designed according to the shape and size of the object to be heated 90, without specific limitations. For example, if the heating chamber 70b is used to heat multiple face masks, then the length of the heating chamber 70b must be greater than the length of the face mask, the width of the heating chamber 70b must be greater than the width of the face mask, and the height of the heating chamber 70b must be greater than the thickness of the multiple face masks, so as to ensure that all the face masks can be placed in the heating chamber 70b for heating.

[0109] The second base plate 1113 serves as the heating body of the heating device 70. The second base plate 1113 has a receiving surface for receiving the object to be heated 90. The semiconductor cooler 112 has a high-temperature end thermally connected to the first base plate 1111 of the heat sink 111, and a low-temperature end thermally connected to the heat-conducting element 113. The semiconductor cooler 112 utilizes the low-temperature end to provide cooling to the refrigerator compartment, while simultaneously utilizing the high-temperature end to provide heat to the heating device 70. The heat sink 111 absorbs heat from the high-temperature end of the semiconductor cooler 112. This heat is transferred from the first base plate 1111 to the second base plate 1113; therefore, the second base plate 1113 can serve as the heating body of the heating device 70. The side of the second base plate 1113 facing the heating cavity 70b is a receiving surface. This receiving surface is flat, ensuring temperature uniformity on its surface and in the heating cavity 70b, thereby improving the temperature uniformity of the object to be heated 90 after heating.

[0110] A heat insulation plate 72 surrounds the second base plate 1113 and connects the second base plate 1113 and the top cover 412. The heat insulation plate 72 is the side wall of the heating device 70. The second base plate 1113 is the bottom wall of the heating device 70 and is used to provide heat to the heating chamber 70b, thereby raising the temperature of the heating chamber 70b.

[0111] After placing the object to be heated 90 on the second base plate 1113, the cover plate 71 is placed over the opening 70a of the heating chamber 70b. The cover plate 71 presses the object to be heated 90 against the second base plate 1113, ensuring that the surface of the object to be heated 90 is as close as possible to the surface of the second base plate 1113, thereby increasing the heating area and improving the temperature uniformity of the object to be heated 90. It also creates localized insulation, preventing heat loss from the object to be heated 90, accelerating the heating rate, and improving the heating effect. The heating device 70 is located on the top of the refrigerator 1000. The user can remove the object to be heated 90 from the refrigerator compartment 20, adjust the control panel 441 to activate the heating mode and close the door 50, then place the object to be heated 90 into the heating chamber 70b. This reduces the time the door 50 is open, lowers cold air loss, and is more energy-efficient and environmentally friendly.

[0112] In some embodiments, the second base plate 1113 has a first fixing hole 1113a. The heat sink 111 further includes heat dissipation fins 1112 fixed to or integrally formed between the first base plate 1111 and the second base plate 1113. The first base plate 1111 has a second fixing hole 1111a that mates with the first fixing hole 1113a. The heat dissipation fins 1112 have clearance channels 1112b that mate with the first fixing hole 1113a and the second fixing hole 1111a. The partition 116 may have a third fixing hole (not shown) that mates with the first fixing hole 1113a, the second fixing hole 1111a, and the clearance channel 1112b. The heat sink 111 and the partition 116 are connected as a whole by fasteners that mate with the first fixing hole 1113a, the second fixing hole 1111a, the clearance channel 1112b, and the third fixing hole.

[0113] The clearance channel 1112b of the heat dissipation fins 1112 is the gap between adjacent heat dissipation fins 1112. The plane on which the heat dissipation fins 1112 are located is parallel to the front panel 44. Adjacent heat dissipation fins 1112 are spaced apart by a certain distance, so that a plurality of heat dissipation channels 1112a connecting the air inlet 40a and the air outlet 40b are formed between adjacent heat dissipation fins 1112. In some embodiments, the vertical distance between adjacent heat dissipation fins 1112 corresponding to the clearance channel 1112b is greater than the vertical distance between adjacent heat dissipation fins 1112 corresponding to the heat dissipation channel 1112a, so as to avoid the fasteners connecting the radiator 111 and the partition 116, including but not limited to screws. The structure of the radiator 111 is easy to extrude, which is beneficial for opening corresponding fixing holes in the first base plate 1111 and the second base plate 1113. The first base plate 1111 and the second base plate 1113 of the radiator 111 are flat, which not only facilitates connection with other electrical components, but also helps to provide uniform heat to the heating device 70.

[0114] Adjacent heat dissipation fins 1112 have several heat dissipation channels 1112a connecting the air inlet 40a and the air outlet 40b. The heat dissipation fins 1112 are parallel to each other, making the heat dissipation fins 1112 parallel to the direction of airflow, facilitating the smooth passage of airflow through the heat dissipation channels 1112a. The air inlet surface of the fan 13 faces the heat dissipation fins 1112, and the air outlet surface faces the air outlet 40b. Driven by the fan 13, air from outside the electrical compartment 10 can enter the electrical compartment 10 through the air inlet 40a, pass through the radiator 111 and exchange heat with the radiator 111, and then flow out through the air outlet 40b. In this process, the electrical components inside the electrical compartment 10 can be cooled, thereby regulating the temperature inside the electrical compartment 10.

[0115] In some embodiments, the heating device 70 further includes a temperature sensing element 15 for detecting the temperature of the second base plate 1113. The temperature sensing element 15 is electrically connected to the control board 12. By detecting the temperature of the second base plate 1113 through the temperature sensing element 15, the problem of the heated object 90 or the heat sink 111 being damaged due to excessively high temperatures can be avoided.

[0116] In some embodiments, the heating device 70 also includes an alarm device (not shown), which is electrically connected to the control board 12. The heating device 70 can have two operating modes: a heating mode and a non-heating mode. The alarm device is used to issue an alarm when the heating device 70 switches from the heating mode to the non-heating mode to remind the user to remove the object 90 to be heated.

[0117] The object to be heated 90 is placed in the heating chamber 70b of the heating device 70. After the cover plate 71 is closed on the chamber opening 70a, the preset temperature T is set through the operation panel 441, and the heating mode is turned on. The operation panel 441 transmits the preset temperature T to the control board 12. The control board 12 detects whether the special storage refrigerator 1000 has entered the heating mode. When it is determined that the special storage refrigerator 1000 has entered the heating mode, the control board 12 controls the fan 13 to stop running or run at the speed of the heating mode, so that the object to be heated 90 continues to be heated. A comparator (not shown) electrically connected to the control board 12 is installed in the electrical compartment 10. The temperature detected by the temperature sensing element 15 is the actual temperature T1. The comparator compares the preset temperature T and the actual temperature T1, and the comparator feeds back the comparison result to the control board 12. The control board 12 controls the operation of the fan 13 based on the comparison result of the preset temperature T and the actual temperature T1. When the actual temperature T1 equals the preset temperature T, the control board 12 activates the alarm device to issue an alarm, reminding the user to remove the object to be heated 90. After the alarm device issues an alarm, the fan 13 operates in non-heating mode to cool the radiator 111, thereby protecting the semiconductor cooler 112 and the object to be heated 90.

[0118] In some embodiments, the preset temperature is greater than or equal to 40°C and less than or equal to 65°C, that is, the range of the preset temperature is 65°C ≥ T ≥ 40°C, and the preset temperature can be 40°C, 43°C, 45°C, 48°C, 55°C, 56°C, 57°C, 58°C, 59°C, 60°C, 61°C, 62°C, 63°C, 64°C, or 65°C.

[0119] In some embodiments, the refrigerator 1000 may also replace the heating device 70 with a heating mechanism 80. See also Figures 20 to 23 , Figure 20 This is a three-dimensional structural schematic diagram of one embodiment of a refrigerator with a heating mechanism provided in this application; Figure 21 This is a schematic diagram of the disassembled structure of the refrigerator with a heating mechanism provided in this application; Figure 22 This is a cross-sectional structural diagram of the refrigerator with a heating mechanism provided in this application; Figure 23 This is a cross-sectional view of the side of the refrigerator with a heating mechanism provided in this application.

[0120] The heating mechanism 80 includes a heat insulation cover 81, which covers the radiator 111 to form a groove. This groove is the heating groove 80b of the heating mechanism 80. The heating groove 80b has a slot 80a, which is aligned with the opening of the refrigerator compartment 20. When the door is closed in the opening of the refrigerator compartment 20, the door can also block the slot 80a of the heating groove 80b, avoiding the need for a separate door to block or open the slot 80a. The first base plate 1111 of the radiator 111 faces the refrigerator compartment 20, and the second base plate 1113 has a receiving surface for receiving the heated item 90. The heat insulation cover 81 is placed over the receiving surface. The heat sink 111 absorbs heat from the high-temperature end of the semiconductor cooler 112. The heat is transferred from the first base plate 1111 to the second base plate 1113, and then from the second base plate 1113 to the heating bath 80b, causing the heating bath 80b to heat up and thus uniformly heating the object 90 to be heated. The second base plate 1113 provides heat to the heating bath 80b, causing it to heat up. The specific shape and size of the heating bath 80b can be designed according to the shape and size of the object 90 to be heated, without specific limitations. For example, if the heating bath 80b is used to heat multiple face masks, the length of the heating bath 80b must be greater than the length of the face masks, the height of the heating bath 80b and / or the opening 80a must be greater than the thickness of the multiple face masks, and the width of the heating bath 80b and / or the opening 80a must be greater than the width of the face masks to ensure that the face masks can be completely placed inside the heating bath 80b for heating.

[0121] In some embodiments, the heat insulation cover 81 includes a first wall 811, a second wall 812, and a third wall 813. The first wall 811 is disposed opposite to both sides of the heating groove 80b, the second wall 812 is disposed on the side of the first wall 811 facing away from the groove opening 80a, and the third wall 813 is disposed on the side of the first wall 811 facing away from the second base plate 1113. That is, the third wall 813 is disposed opposite to the second base plate 1113, and the first wall 811 and the second wall 812 surround the third wall 813 and the second base plate 1113 and are disposed between the third wall 813 and the second base plate 1113. The plane containing the first wall 811 is perpendicular to the plane containing the third wall 813 or forms an angle with the plane containing the third wall 813; the plane containing the first wall 811 is perpendicular to the plane containing the second base plate 1113 or forms an angle with the plane containing the second base plate 1113. The plane containing the second wall 812 is perpendicular to the plane containing the third wall 813 or forms an angle with the plane containing the third wall 813; the plane containing the second wall 812 is perpendicular to the plane containing the second base plate 1113 or forms an angle with the plane containing the second base plate 1113. The heating mechanism 80 has a simple structure, which reduces assembly difficulty and improves production efficiency.

[0122] In some embodiments, the heat insulation cover 81 can be a one-piece molded structure, that is, the first wall 811, the second wall 812, and the third wall 813 are different parts of the same component. The heat insulation cover 81 can also be a combined structure in which the first wall 811, the second wall 812, and the third wall 813 are fixedly connected, and the fixed connection method includes, but is not limited to, riveting, welding, bonding, magnetic adsorption, and other connection methods.

[0123] The air duct cover 41 also includes a top cover 412 and a baffle 416 fixed to or integrally formed with the top cover 412. The baffle 416 is disposed opposite to both sides of the second base plate 1113. The side of the baffle 416 away from the top cover 412 abuts against the second base plate 1113. The baffle 416 and the top cover 412 cooperate to cover the heat insulation cover 81. The baffle 416 structure can limit the cooling of the receiving surface of the second base plate 1113 by the outside air flowing into the air inlet 40a, thus ensuring the heating efficiency and heat preservation effect of the heating mechanism 80 when the refrigerator 1000 enters the heating mode.

[0124] The second base plate 1113 has a first mounting hole 82a. The first wall 811 has an extension 814 disposed opposite to it, the plane of which the extension 814 is in contact with the second base plate 1113, and the extension 814 has a second mounting hole 814a corresponding to the first mounting hole 82a. The heat insulation cover 81 is fixed to the radiator 111 by means of a fastener that engages with the first mounting hole 82a and the second mounting hole 814a, that is, the heat insulation cover 81 is fixed to the second base plate 1113 of the radiator 111.

[0125] The front panel 44 also has a second through hole 44b. The front panel 44 extends from the electrical compartment 10 to the collection compartment 30. The first through hole 44a corresponds to the opening of the refrigerator compartment 20. The operation panel 441 corresponds to the control panel 12 and is electrically connected to the control panel 12. The second through hole 44b corresponds to the slot 80a of the heating tank 80b, that is, the slot 80a of the heating tank 80b faces the front panel 44 and the slot 80a of the heating tank 80b is set in the same direction as the opening of the refrigerator compartment 20. After the object 90 to be heated is taken out of the refrigerator compartment 20, it can be placed into the heating tank 80b through the slot 80a to enter the heating mode. The operation panel 441 corresponds to the control panel 12 and is located on the side of the front panel 44 facing away from the control panel 12, which facilitates the electrical connection between the operation panel 441 and the control panel 12. The position of the operation panel 441 close to the control panel 12 avoids long-distance wiring and reduces wiring difficulty. At the same time, it reduces the loss of the control board 12, avoids excessive heat generation of the control board 12, ensures the stability of the electrical connection between the operation panel 441 and the control board 12, and avoids the risk of accidental coupling caused by electromagnetic interference to a certain extent.

[0126] In some embodiments, the edge of the slot 80a abuts against the front panel 44, ensuring the airtightness between the electrical chamber 10 and the heating mechanism 80. The abutment method includes, but is not limited to, riveting, welding, bonding, and magnetic adsorption. The side of the radiator 111 closest to the front panel 44 is in contact with the front panel 44, and heat insulation material can be filled between the radiator 111 and the front panel 44. Since both the side of the radiator 111 closest to the front panel 44 and the edge of the slot 80a are connected to the front panel 44, the heating slot 80b can only communicate with the outside through the slot 80a and cannot communicate with the electrical chamber 10. This, to a certain extent, prevents the heating slot 80b from communicating with the air outlet 40b and the air inlet 40a for heat exchange, thus improving the heat preservation effect of the heating slot 80b. Therefore, the outside air flowing in from the air inlet 40a cannot be discharged from the heat sink 80a, preventing the high-temperature air inside the appliance compartment 10 from flowing out from the sink 80a under the action of the fan. This avoids the high-temperature airflow inside the appliance compartment 10 from flowing out from the sink 80a and spreading to the human body when the door 50 is opened, thus preventing harm to the human body. This ensures the heat dissipation effect of the refrigerator 1000, the cooling effect of the refrigerator compartment 20, and the heat preservation effect of the heating mechanism 80.

[0127] In some embodiments, the object to be heated 90 is placed from the slot 80a into the heating tank 80b. The object to be heated 90 is thermally connected to the second base plate 1113 by its own gravity, and the second base plate 1113 transfers heat to the object to be heated 90, thereby raising the temperature of the object to be heated 90. Using the temperature of the second base plate 1113 to heat the object to be heated 90 avoids the need for a separate heater, offering advantages such as space saving, resource conservation, energy saving, and environmental protection. Since the slot 80a and the opening of the refrigerator compartment 20 are located on the same side, it is convenient for the user to remove the object to be heated 90 from the refrigerator compartment 20, immediately transfer it to the heating mechanism 80, then adjust the operation panel 441 to turn on the heating mode, and finally close the door 50 onto the cabinet 500. After the door 50 is closed, the heating tank 80b can be sealed by the attraction of the first magnetic suction member 442 and the second magnetic suction member. The structural design of the heating mechanism 80 makes the process of removing the object to be heated 90 from the refrigerator compartment 20 and transferring it to the heating mechanism 80 for heating simpler.

[0128] The front panel 44, facing the refrigerator compartment 20, has a first magnetic member 442 arranged circumferentially along the inner liner 21. The door seal 51 is embedded with a second magnetic member that cooperates with the first magnetic member 442 on the front panel 44. After the door 50 closes to the cabinet 500, the first magnetic member 442 attracts the second magnetic member to seal the refrigerator compartment 20. Therefore, when the refrigerator 1000 activates the heating mode and closes the door 50, the low-temperature airflow in the refrigerator compartment 20 cannot escape from the opening of the refrigerator compartment 20, preventing heat exchange between the heating element 80b and the refrigerator compartment 20. The heating mechanism 80 and the refrigerator compartment 20 operate independently without interference. The heat source of the heating mechanism 80 comes from the high-temperature end of the semiconductor cooler 112, and the cold source of the refrigerator compartment 20 comes from the low-temperature end of the semiconductor cooler 112. This multi-functional design makes the structure more compact, saving usable space in the refrigerator 1000 and avoiding resource waste.
