Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to an air-cooled refrigerator. Background Art

[0002] In current technology, air-cooled refrigerators are generally equipped with a cooling source and a fan, which are installed in the air duct behind the refrigerator storage compartment. The fan generates a circulating airflow from the cooling source to the storage compartment to cool the storage compartment.

[0003] The air duct outlet is generally located at the back of the refrigerator storage compartment. The cold air from the air duct is sent forward from the back of the storage compartment. The temperature near the air outlet is the lowest. However, due to the structure and usage characteristics of the refrigerator, the temperature of the refrigerator door and door seal is relatively high, which will cause the temperature inside the refrigerator storage compartment to be uneven, which is not conducive to the storage of items in the refrigerator.

[0004] However, it can only cool the inner tank directly, and cannot cool the inside of the refrigerator synchronously, so that the external heat can still easily affect the cooling effect of the refrigerator, thereby making the cooling effect of the refrigerator poor.

[0019] Through the design of the heat dissipation mechanism, the inner tank can be cooled and the heat in the inner tank can be exchanged with cold at the same time, thereby improving the cooling effect of the inner tank.

[0025] Through the design of the air outlet and the sealing plate, when new cold air enters the recycling chamber, the cold air stored in the recycling chamber will flow to the air outlet, thereby pushing the sealing plate at the air outlet opening to rise. As the sealing plate rises, a gap appears between the air outlet and the sealing plate, and this part of the cold air can be discharged to the outside. After this part of the cold air is discharged, under the action of the sealing plate's own weight and with the guidance of the slider and the slide groove, the sealing plate descends to seal the opening of the air outlet again.

The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0037] According to an embodiment of the present invention, an air-cooled refrigerator is provided.

[0038] Example 1, as Figure 1-6 As shown, an air-cooled refrigerator according to an embodiment of the present invention includes a shell 1, an inner cavity 2 is provided in the shell 1, an inner liner 3 is provided in the inner cavity 2, a first thermal insulation layer 4 is provided between the inner cavity 2 and the inner liner 3, a placement cavity is provided inside the inner liner 3, and a heat dissipation mechanism is provided outside the inner cavity 2, the heat dissipation mechanism includes a refrigeration cavity 21 opened above the inner cavity 2, a fan 22 and a cold source 23 are provided inside the refrigeration cavity 21, a transfer cavity 16 is provided at the bottom of the refrigeration cavity 21, and the bottom of the transfer cavity 16 is connected to a first heat dissipation component and a second heat dissipation component that cooperate with the inner liner 3, and a sealed door 1 30 and a sealed door 2 31 and a touch screen 32 are provided on the outer surface of the shell 1 that cooperate with the placement cavity and the refrigeration cavity 21; through the design of the heat dissipation mechanism, the inner liner 3 can be cooled, and the heat at the inner liner 3 can be exchanged with cold and heat, thereby improving the cooling effect of the inner liner 3, and the cold air after the cold and heat exchange can also be discharged from the outside of the shell 1 for cooling treatment.

[0039] Example 2, as Figure 1-3 As shown, the first heat dissipation component includes a delivery pipe 18 connected at the center of the bottom of the transfer chamber 16 and a U-shaped hollow member 19 located in the inner wall of the inner liner 3. The bottom end of the delivery pipe 18 is connected and penetrated with the inner top of the U-shaped hollow member 19. A plurality of air outlet pipes 20 are provided on both sides of the interior of the U-shaped hollow member 19. The other end of the air outlet pipe 20 passes through the inner liner 3 and extends to the inner outer surface of the placement chamber. It is not difficult to see from the above design that, through the design of the first heat dissipation component, the cold air output from the transfer chamber 16 can be transported to the U-shaped hollow member 19, and the U-shaped hollow member 19 will be output to the placement chamber through the plurality of air outlet pipes 20, thereby cooling the food stored in the placement chamber.

[0040] Example 3, as Figure 1 、 2As shown in Figure 4, the second heat dissipation component includes a heat dissipation cavity 5 opened on both sides of the inner cavity 2, a circulating air cooling pipe 11 is provided inside the heat dissipation cavity 5, a heat sink 6 is provided on the circulating air cooling pipe 11, the other end of the heat sink 6 is connected to the inner liner 3, a slow wind component is provided inside the circulating air cooling pipe 11 corresponding to the heat sink 6, the top end of the circulating air cooling pipe 11 is connected and penetrated with the inner bottom side of the transfer cavity 16, and the bottom end of the circulating air cooling pipe 11 is connected to the recycling component. It is not difficult to see from the above design that through the design of the second heat dissipation component, the cold air located on the side of the transfer cavity 16 can be transported to the circulating air cooling pipe 11, and the heat of the inner liner 3 will be transferred to the circulating air cooling pipe 11 through the heat sink 6, and the flowing cold air will take away the heat through the heat exchange with the inner wall of the circulating air cooling pipe 11.

[0041] Example 4, as Figure 5 As shown, the heat sink 6 includes a heat sink 7 and a heat pipe 9. The heat sink 7 is fixed to the outer surface of the inner tank 3. The heat pipe 9 is sleeved on the outer surface of the circulating air cooling pipe 11. The heat sink 7 and the heat pipe 9 are connected by a heat sink 8. A heat sink connector 10 is provided inside the heat pipe 9. The other end of the heat sink connector 10 passes through the circulating air cooling pipe 11 and is connected to the slow wind component. It is not difficult to see from the above design that through the design of the heat sink 6, the heat on the inner tank 3 can be transferred to the circulating air cooling pipe 11 and the diverter block 24 respectively, thereby facilitating the cold air in the second heat sink component to perform heat exchange.

[0042] Example 5, as Figure 6-7 As shown, the slow-wind assembly includes a diverter block 24 fixed in the middle of the circulating air-cooling pipe 11 and guide plates 25 fixed on the inner walls of both sides of the circulating air-cooling pipe 11. The end of the heat dissipation connector 10 extends into the circulating air-cooling pipe 11 and is connected to the diverter block 24. The outer surface of the diverter block 24 is provided with an air inlet channel 26 on both sides. The end of the guide plate 25 extends to the opening of the air inlet channel 26. The ends of the air inlet channels 26 are connected to the air outlet channel 27. The other end of the air outlet channel 27 is connected to the air outlet 29 located on the outer surface of the diverter block 24. The air outlet channel 27 is provided with an inclined plate guide 28 that cooperates with the air inlet channel 26. It is not difficult to see from the above design that the design of the slow-wind assembly slows down the speed of the cold air flowing in the circulating air-cooling pipe 11, improves the cooling effect of the cold air, provides sufficient time for the circulating air-cooling pipe 11 and the diverter block 24 to exchange heat, and thus improves the heat exchange effect of the inner liner 3.

[0043] Example 6: Figure 1-2As shown, the recycling component includes a recycling chamber 12 opened on the outside of the heat dissipation chamber 5, the bottom end of the circulating air cooling pipe 11 is connected and connected to the recycling chamber 12, the top of the recycling chamber 12 is connected and connected to the air outlet 13, the top of the air outlet 13 is connected to the top outer surface of the shell 1, and a blocking plate 14 is slidably connected in the air outlet 13, and the blocking plate 14 blocks the connection between the air outlet 13 and the recycling chamber 12. It is not difficult to see from the above design that through the design of the recycling component, the cold air discharged from the circulating air cooling pipe 11 can be transported to the recycling chamber 12, and the cold air is stored inside the recycling chamber 12. The remaining cold in the cold air will be transferred to the inner wall of the recycling chamber 12, thereby improving the cooling effect of the shell 1 and reducing the influence of external heat on the inner tank 3.

[0044] Example 7, as Figure 2 As shown, sliders are fixed to the middle of both sides of the blocking plate 14, a slide groove that matches the slider is opened on the inside of the air outlet 13, and a partition block 17 is provided on both sides of the inner bottom of the transfer chamber 16. A second heat insulation layer 15 is provided inside the shell 1 and on the outside of the recycling chamber 12. A temperature sensor is provided inside the inner liner 3, and a battery and a controller are provided inside the shell 1. The battery, the temperature sensor, the touch screen 32, the fan 22, and the cold source 23 are all electrically connected to the controller. It is not difficult to see from the above design that the design of the slide groove and the slider improves the stability of the vertical movement of the blocking plate 14, and the design of the partition block 17 blocks the flow of cold air inside the transfer chamber 16, so that a small amount of cold air inside the transfer chamber 16 flows to the circulating air cooling pipe 11.

[0045] During use, the fan 22 delivers the cold air output by the cold source 23 to the interior of the transfer chamber 16. The cold air inside the transfer chamber 16 is blocked by the partition block 17. Most of the cold air is delivered to the U-shaped hollow member 19 in the inner container 3 through the delivery pipe 18. The U-shaped hollow member 19 is output to the storage chamber through a plurality of air outlet pipes 20 to cool the food stored in the storage chamber. The remaining cold air in the transfer chamber 16 flows through the gap between the partition block 17 and the inner wall of the transfer chamber 16 to the side of the transfer chamber 16 and enters the interior of the circulating air cooling pipe 11.

[0046] The heat sink 6 transfers the heat from the inner tank 3 to the circulating air cooling pipe 11 and the diverter block 24 through the heat sink 8 and the heat dissipation connector 10, so that the cold air flowing in the circulating air cooling pipe 11 will take away the heat on the circulating air cooling pipe 11;

[0047] The cold air will collide with the heat dissipation component while flowing, thereby slowing down the speed of the cold air flowing in the circulating air-cooling pipe 11, improving the cooling effect of the cold air, and providing sufficient time for heat exchange. That is, the cold air will flow to both sides of the inner wall of the circulating air-cooling pipe 11 under the action of the diverter block 24. During the flow, the two streams of cold air will collide with the two guide plates 25, and then under the guidance of the guide plates 25, the cold air will enter the air inlet channel 26. The two streams of cold air will enter the air outlet channel 27 through the air inlet channel 26, and then be discharged to the inside of the circulating air-cooling pipe 11 through the air outlet 29. The heat transferred to the diverter block 24 by the heat dissipation connector 10 will also be taken away by the cold air in the above-mentioned flow process, and then all the heat transferred from the inner tank 3 can be taken away through the circulating air-cooling pipe 11 and the diverter block 24;

[0048] The cold air that has undergone heat exchange in the circulating air cooling pipe 11 will eventually be discharged into the recycling chamber 12. At this moment, the cold air is stored inside the recycling chamber 12, and the remaining cold energy in the cold air will be transferred to the inner wall of the recycling chamber 12, thereby improving the refrigeration effect of the shell 1 and reducing the influence of external heat on the inner tank 3. When the cold air in the subsequent circulating air cooling pipe 11 enters the recycling chamber 12 again, the cold energy of the cold air previously discharged from the recycling chamber 12 is also consumed. At the same time, this part of the cold air will be squeezed and pushed by the subsequent cold air, so that this part of the cold air will flow to the air outlet 13, thereby pushing the sealing plate 14 at the opening of the air outlet 13 to rise. As the sealing plate 14 rises, the air outlet 13 and the sealing plate 14 are The cold air discharged from the air outlet 13 can also cool the surrounding environment. Because the refrigerator is placed in a small space such as a desk or cabinet, the cold air discharged will also improve the comfort of the people around it, thereby improving the energy recovery rate.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
