[0024] The present invention is further described below in conjunction with specific embodiments:
[0025] An air-cooled direct-cooling dual-temperature freezer comprises a cabinet body 1 and a door body for closing the cabinet body 1, such as Figure 1As shown, the cabinet 1 is square, and the cabinet 1 includes an outer shell and an inner tank installed in the outer shell. In this patent, two inner tanks are provided, and the two inner tanks are arranged on the left and right, and the freezing chamber 11 and the refrigerating chamber 12 are formed in each inner tank respectively; an evaporation chamber 13 is provided on one side of the freezing chamber 11, and the evaporation chamber 13 is provided with an air supply port 131 and a return air port 132 connected to the freezing chamber 11. A fan 5 is also provided in the cabinet 1, and the fan 5 is used to transport the cold air in the evaporation chamber 13 along the air supply port 131 to the freezing chamber 11, and return it to the evaporation chamber 13 from the return air port 132; the refrigeration element 3 is also connected to a refrigeration pipe 133, and the refrigeration pipe 133 is attached to the refrigerating chamber 12 for realizing the refrigeration of the refrigerating chamber 12.
[0026] Combination Figure 2 , 3 As shown, the inner tank is square, the freezing chamber 11 is a chamber body embedded in one side of the inner tank, and the refrigerating chamber 12 is located at one end of the freezing chamber 11 away from the evaporation chamber 13; an installation space is formed below the chamber body, and the refrigeration element 3 is arranged in the installation space and the chamber body, wherein the refrigeration element 3 includes a compressor 32 arranged in the installation space and an evaporator 31 located in the evaporation chamber 13. Specifically, as Figure 2 , 3 As shown, the evaporation chamber 13 is provided with an air supply port 131 and an air return port 132 which are connected to the freezer chamber 11. A fan 5 is also provided in the cabinet body 1. The fan 5 is used to transport the cold air in the evaporation chamber 13 to the freezer chamber 11 along the air supply port 131, and return it to the evaporation chamber 13 from the air return port 132; the air supply port 131 is formed on the top of the cabinet body, and is connected to the freezer chamber 11; the evaporation chamber 13 is arranged on a side of the evaporator 31 close to the air supply port 131. When working, the refrigerant is sent into the evaporator 31 by the compressor 32 to cool the gas at the edge of the evaporator 31, and then the cold air is blown into the freezer chamber 11 from the air supply port 131 by the fan 5 to achieve air cooling of the freezer chamber 11. The return air port 132 is arranged at the bottom of the warehouse body. After the cold air enters the freezing chamber 11, the cold air will sink. Therefore, the return air port 132 is arranged at the bottom of the warehouse body. The sinking cold air re-enters the evaporation chamber 13 under the action of the fan 5 to achieve circulation. Specifically, a plurality of filter baffles are arranged on the return air port 132 to prevent foreign matter from entering the evaporation chamber 13 from the return air port 132 and affecting the normal operation of the evaporation chamber 13. Since the freezing chamber 11 in the present patent cools the freezing chamber 11 by air cooling, the air cooling has the advantage of preventing the freezing chamber 11 from frosting, reducing the difficulty of later user maintenance.
[0027] Furthermore, the refrigeration element 3 is also connected to a refrigeration pipe 133, and the refrigeration pipe 133 is attached to the refrigeration chamber 12 to achieve refrigeration of the refrigeration chamber 12. Figure 4 As shown, the refrigeration pipe 133 is connected to the outer wall of the evaporation chamber 13, and a pipe seat connected to the refrigeration pipe 133 is provided on the outer wall of the evaporation chamber 13, and the refrigeration pipe 133 extends outward from the pipe seat. In this patent, the refrigeration pipe 133 passes through the outer wall of the freezing chamber 11 to the outer wall of the refrigeration chamber 12, and the end of the refrigeration pipe 133 returns to the outer wall of the freezing chamber 11, and then flows back to the compressor 32 to realize the circulation of the refrigerant. At the same time, the refrigerant flows through the refrigeration pipe 133, and then heat exchanges with the refrigeration chamber 12 through the refrigeration pipe 133 for refrigeration.
[0028] In summary, the present patent freezes the freezer compartment 11 by air cooling, and refrigerates the refrigerator compartment 12 by the refrigeration pipe 133. Since the freezer compartment 11 in the present patent cools down the freezer compartment 11 by air cooling, the air cooling has the advantage of preventing the freezer compartment 11 from frosting. At the same time, through the bypass refrigeration pipe 133 structure, the two compartments can work simultaneously, realizing the two functions of freezing and refrigeration.
[0029] Furthermore, the door body includes a first door body 21 enclosed on the refrigerating chamber 12 and a second door body 22 enclosed on the freezing chamber 11, and the second door body 22 is provided with an inwardly concave guide surface 23. Figure 1 , 5 As shown, the first door body 21 and the second door body 22 are fixed to the cabinet body 1 through a hinge structure, and the first door body 21 and the second door body 22 are opened by flipping. The guide surface 23 is directly formed on the first door body 21 and the second door body 22, and the guide surface 23 is concave inwardly. The air supply port 131 is located at one end of the guide surface 23, and the cold air sent from the air supply port 131 flows downwardly from the other end of the guide surface 23 along the concave guide surface 23, so as to realize the downward guide of the cold air, so that the cold air can work better in the freezer 11.
[0030] Furthermore, the guide surface 23 is provided with a plurality of partition ribs 231 arranged along the cold air delivery direction, and the partition ribs 231 are provided with a plurality of strips, and a guide channel for guiding the cold air is formed between adjacent partition ribs 231, so as to better guide the cold air. At the same time, the guide surface 23 is also provided with a protruding guide bar 232, and the guide bar 232 is arranged perpendicular to the partition ribs 231. When the cold air moves along the guide channel, it will contact the protruding guide bar 232, so that the cold air is guided downward into the freezing chamber 11. Furthermore, the air supply port 131 is arranged to be inclined toward the freezing chamber 11, so that the outflow direction of the cold air corresponds to the freezing chamber 11, so that the cold air can better enter the freezing chamber 11 for work.
[0031] Furthermore, a support shelf 4 is provided at the bottom of the freezing chamber 11, and the support shelf 4 has an isolation cover 41 provided on the return air outlet 132. Figure 2 , 3 As shown, the support shelf 4 is a metal frame, which is adapted to the shape and size of the bottom of the freezing chamber 11. The support shelf 4 includes a panel and a support leg 42 arranged under the panel. The support shelf 4 is placed in the freezing chamber 11 through the support leg 42, and the panel is used to support the frozen objects. Since the return air port 132 is located at the bottom of the evaporation chamber 13, correspondingly, the return air port 132 is located at the lower position of the freezing chamber 11 and is located on one side of the support shelf 4; therefore, the isolation cover 41 is formed on the side end of the support shelf 4, which is specifically a cover body. When the support shelf 4 is installed in the freezing chamber 11, the isolation cover 41 is also covered on the return air port 132, and the isolation cover 41 is used to prevent debris from entering the evaporation chamber 13 from the return air port 132.
[0032] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
