[0002] Existing refrigerated or cold storage containers can be used as transportation and storage tools for frozen or refrigerated items. However, in actual use, different items often have different temperature requirements. To meet the need to load these items with different preservation temperature requirements in one container, multi-chamber dual-temperature containers have been manufactured, and the temperature of each chamber is adjustable.
[0003] Existing dual-temperature containers generally divide the box body into two chambers, a freezer and a refrigerator, by a partition, and a unidirectional air supply fan is provided on the partition. The temperature of the freezer is regulated by a refrigeration unit, while the temperature of the refrigerator is adjusted by blowing cold air into the refrigerator through the unidirectional fan to regulate the temperature of this chamber. If this temperature regulation method is adopted, it is difficult to accurately regulate the temperature inside the refrigerator only through the unidirectional fan. If a refrigeration unit is also configured in the refrigerator to regulate the temperature, this will undoubtedly increase the manufacturing cost of the container.
[0004] Therefore, the utility model proposes a dual-temperature fan box and a dual-temperature container. Summary of the Utility Model

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0038] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0039] Combined with Figures 1 to 6 As shown, the present invention proposes a dual - temperature fan box and a dual - temperature container. First of all, it should be noted that the dual - temperature container 1 of the present invention mainly includes a front chamber 11 and a rear chamber 12. Among them, the front chamber 11 is set as a freezer, and the rear chamber 12 is set as a refrigerator. The temperature of the freezer is regulated by a refrigeration unit, and a dual - temperature fan box is arranged at the top of the rear chamber 12, and the dual - temperature fan box is used to regulate the temperature of the rear chamber 12.
[0040] Combined with Figures 3 to 6 As shown, the dual - temperature fan box mainly includes a box body 2, a fan 23, a heater 24 and other structural components. Through this dual - temperature fan box, the temperature of the air sent into the refrigerator can be adjusted, and then the temperature of the refrigerator can be controlled and regulated.
[0041] Combined with Figure 6 As shown, the top plate of the box body 2 is provided with a cold air inlet 201 and a hot air inlet 202 arranged side by side. Both the cold air inlet 201 and the hot air inlet 202 are arranged in the middle of the top plate of the dual - temperature fan box body 2, and there are two cold air inlets 201 and two hot air inlets 202 respectively. The two cold air inlets 201 are arranged in the middle, and the two hot air inlets 202 are arranged on both sides. A partition is provided between the adjacent hot air inlet 202 and cold air inlet 201, which can prevent the air flow from mixing outside the box body 2. A partition is also provided between the two cold air inlets 201 to facilitate the precise control of the cold air entering the box body 2. Combined with Figure 1 andFigure 2 As shown, the cold air inlet 201 is connected to the front chamber 11 through the air duct 3 in the thermal insulation sandwich of the top plate of the double-temperature container 1. The low-temperature cold air in the freezer can be sent into the interior of the box body 2 through the air duct 3 and the cold air inlet 201. A side hole 204 is formed in the side wall of the box body 2, and the side hole 204 is connected to the hot air inlet 202. The hot air in the refrigerating chamber enters the interior of the box body 2 successively through the side hole 204 and the hot air inlet 202.
[0042] Combined with Figure 3 and Figure 4 As shown, a slide rail 211 is arranged inside the box body 2, and a wind baffle 212 is slidably matched on the slide rail 211. Among them, a wind baffle 212 is arranged on the back side of each of the hot air inlet 202 and the cold air inlet 201. The wind baffle 212 can block the hot air inlet 202 and the cold air inlet 201, thereby indirectly affecting and changing the gas temperature inside the box body 2, so that the temperature of the mixed air reaches the temperature required by the refrigerating chamber. The area of the wind baffle 212 at the cold air inlet 201 is not less than the area of the region occupied by the cold air inlet 201. This setting enables the wind baffle 212 to completely block the cold air inlet 201. When heating operation is required, it can prevent the cold air in the freezer from entering the interior of the box body 2 and avoid affecting the heating effect.
[0043] A pushing mechanism is further arranged on the box body 2. The pushing mechanism can drive the wind baffle 212 to move relative to the hot air inlet 202 and / or the cold air inlet 201 to change the opening size of the hot air inlet 202 and / or the cold air inlet 201, thereby changing the air temperature inside the box body 2 after mixing, and finally being able to regulate the temperature of the rear chamber 12. Combined with Figures 3 to 5 As shown, in this embodiment, the pushing mechanism is realized by an electric push rod 221. Two groups of electric push rods 221 are arranged inside the box body 2. Among them, the cylinder end of the electric push rod 221 is connected to the inner wall of the box body 2, and the telescopic end of the electric push rod 221 is connected to the wind baffle 212 through a hinge seat 222. The telescopic end of the electric push rod 221 extends or retracts relative to the cylinder end, which can drive the wind baffle 212 to move relative to the hot air inlet 202 and / or the cold air inlet 201, thereby changing the opening size of the hot air inlet 202 and / or the cold air inlet 201, so that the cold air from the front chamber 11 is mixed with the hot air in the rear chamber 12, and the temperature of the mixed air reaches the temperature required by the rear chamber 12.
[0044] Combined with Figures 3 to 6As shown, a plurality of air outlets 203 are provided on the side wall of the box body 2, and heaters 24 are correspondingly arranged at the air outlets 203. The heaters 24 are used to heat the air to raise its temperature. A blower 23 is arranged at the rear of each group of heaters 24. The blower 23 can convey the mixed air flow to the outside of the box body 2, that is, into the refrigerator compartment, and make a negative pressure environment formed inside the box body 2. The cold air in the freezer compartment can enter the box body 2 of the dual-temperature blower box through the air duct 3.
[0045] Combined with Figures 3 to 4 As shown, a controller 26 is further arranged inside the box body 2. The controller 26 is respectively connected to components such as the electric push rod 221, the heater 24, and the blower 23 by signals. By adding the controller 26, the opening or closing of the heater 24 and the blower 23 can be controlled, and at the same time, the elongation or contraction of the electric push rod 221 can also be controlled, so as to change the opening and closing sizes of the hot air inlet 202 and the cold air inlet 201, and finally the air temperature in the refrigerator compartment can be controlled and adjusted. A temperature sensor and a display screen 25 connected to the controller 26 are also arranged on the box body 2. Among them, the temperature sensor is used to detect the outlet air temperature and the return air temperature. The set temperature and the actual temperature of the front compartment 11 and the rear compartment 12 are displayed on the display screen 25, which is convenient for the staff to intuitively understand the temperatures of the front compartment 11 and the rear compartment 12.
[0046] Combined with Figure 1 and Figure 2 As shown, the present utility model also proposes a dual-temperature container, and this dual-temperature container applies the above-mentioned dual-temperature blower box. Among them, a dual-temperature control module is further arranged inside the dual-temperature container 1. The dual-temperature control module is used for setting the temperature, and the dual-temperature control module is connected to the controller 26 by signals. The staff sets the temperature by operating the dual-temperature control module, so as to drive the controller 26 to adjust the opening and closing sizes of the hot air inlet 202 and the cold air inlet 201, so as to adjust the temperature of the rear compartment 12.
[0047] The working process of the dual-temperature blower box of the present utility model is as follows:
[0048] When refrigeration operation is required, the blower 23 operates, and the air outlet 203 blows air outwards, making a negative pressure formed inside the box body 2. The cold air enters the inside of the box body 2 from the front compartment 11 through the air duct 3 and the cold air inlet 201. The hot air in the rear compartment 12 will enter the inside of the box body 2 through the side holes 204 on both sides and then through the hot air inlet 202. The controller 26 will control the electric push rod 221 to move the wind deflector 212 to adjust the opening and closing sizes of the cold air inlet 201 and the hot air inlet 202, so that the temperature of the mixed air reaches the required temperature of the refrigerator compartment; when heating operation is required, the blower 23 operates, the air outlet 203 blows air outwards, the controller 26 controls the electric push rod 221 to move the wind deflector 212, completely closes the cold air inlet 201, and at the same time turns on a plurality of heaters 24 and blows out hot air.
[0049] The following is an illustration with specific embodiments:
[0050] When the ambient temperature is 38°C, the set temperature of the cooler in the front chamber 11 is -30°C, the current temperature of the rear chamber 12 is 30°C, and the required temperature is -5°C; first, the temperature is set to -5°C through the dual-temperature operation module; second, the dual-temperature operation module transmits the data to the controller 26 inside the cabinet 2, and the controller 26 controls the start of 3 fans 23. At the same time, the temperature sensor detects the outlet air temperature and return air temperature of the mixed air inside the cabinet 2 to determine the required refrigeration mode; finally, the controller 26 controls the electric push rod 221 to move the wind deflector 212 to adjust the opening and closing sizes of the cold air inlet 201 and the hot air inlet 202, and maintains a temperature difference of about 5°C between the outlet and the return air port until the return air port temperature reaches -5°C.
[0051] When the ambient temperature is -20°C, the set temperature of the cooler in the front chamber 11 is -30°C, the current temperature of the rear chamber 12 is -20°C, and the required temperature is 5°C; first, the temperature is set to 5°C at the dual-temperature operation module; second, the dual-temperature operation module transmits the data into the controller 26 inside the cabinet 2, and the controller 26 controls the start of 3 fans. At the same time, the temperature sensor detects the outlet air temperature and return air temperature of the mixed air inside the dual-temperature fan cabinet to determine the required heating mode; the controller 26 controls the electric push rod 221 to move the wind deflector 212 to the middle cold air inlet 201, completely blocking the cold air inlet 201, and turns on the heater 24 until the return air port temperature reaches 5°C.
[0052] The present utility model proposes a dual-temperature fan cabinet and a dual-temperature container. By arranging a fan 23 inside the cabinet 2 of the dual-temperature fan cabinet to exhaust air, a negative pressure environment is formed inside the cabinet 2. The cold air from the freezer enters the inside of the cabinet 2 through the air duct 3 and mixes with the warm air. The controller 26 controls the pushing mechanism to move the wind deflector 212, that is, the telescopic end of the electric push rod 221 extends or retracts relative to the cylinder end to move the wind deflector 212, thereby adjusting the opening and closing sizes of the cold air inlet 201 and the hot air inlet 202, so as to be able to adjust the temperature of the mixed air, and finally the temperature of the refrigerated chamber is regulated; a heater 24 for heating air is also arranged inside the cabinet 2 of the dual-temperature fan cabinet. When heating operation is required, the controller 26 controls the pushing mechanism to move the wind deflector 212 to completely block the cold air inlet 201, and then discharges the heated air to the refrigerated chamber through the fan 23; by installing the dual-temperature fan cabinet on the top of the refrigerated chamber of the dual-temperature container 1, the temperature of the refrigerated chamber can be adjusted and controlled. At the same time, a display screen 25 for displaying the temperature reading is installed on the dual-temperature fan cabinet, and the reading is more intuitive, which is convenient for the staff to view; the internal structure of the dual-temperature fan cabinet of the present utility model is simple, and the later maintenance is relatively convenient, which can save a certain amount of economic cost.
