[0002] A quick-freeze container is a container structure that can quickly cool down and freeze goods. Among the existing quick-freeze container structures, there is a quick-freeze container disclosed in patent CN207791685U, which is equipped with at least two refrigeration units in the container, which can achieve rapid cooling of the goods in the container and pre-cool the goods, so that the ambient temperature in the container can be quickly reduced to a temperature suitable for refrigerated or frozen transportation of the goods.

[0003] However, this type of container has a drawback. The air outlet of the refrigeration unit is generally facing the inside of the box, blowing cold air directly into the box. When the goods on the side close to the air outlet in the box are stacked more and higher, the transmission of cold air will be hindered, so that the goods on the side far from the air outlet cannot be cooled or frozen in time, resulting in uneven freezing effect of the goods. Therefore, the existing quick-freezing containers need to be improved. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] like Figure 1 As shown, the new quick-freezing container of this embodiment includes a box body 1, a box door 2, an air supply bottom plate 3 and a refrigeration system. The box body 1 is divided into a refrigeration chamber 11 and a freezing chamber 12 by a partition 4. The box door 2 is arranged at the end of the freezing chamber 12, the air supply bottom plate 3 is arranged at the bottom of the freezing chamber 12, and the refrigeration system is arranged in the refrigeration chamber 11 and connected to the air supply bottom plate 3 through an air supply channel 5.

[0023] The refrigeration system includes a compressor 6, a condenser 7, a dryer 8, a throttle 9 and an evaporator 10. The evaporator 10 is arranged at the top of the refrigeration chamber 11. A guide plate 13 is obliquely provided below the evaporator 10. The end of the guide plate 13 is connected to the top of the air supply channel 5. The condenser 7 is arranged on the side wall of the refrigeration chamber 11 and is located below the guide plate 13. The compressor 6 is arranged below the condenser 7. The dryer 8 and the throttle 9 are arranged adjacent to the compressor 6.

[0024] A supply fan 14 is provided on the top of the evaporator 10 , a heating wire 15 is provided between the evaporator 10 and the supply fan 14 , a drain port 16 is provided at the bottom of the air supply channel 5 , and an exhaust fan 17 is provided on the outside of the condenser 7 .

[0025] like Figure 2 As shown, the working principle of the refrigeration system is as follows: the compressor 6 works to compress the low-temperature and low-pressure gaseous refrigerant coming out of the evaporator 10 into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser 7. In the condenser 7, the heat of the gaseous refrigerant is taken away by the outside air, so that the high-temperature and high-pressure gaseous refrigerant becomes a normal-temperature and high-pressure liquid refrigerant.

[0026] After the liquid refrigerant passes through the dryer 8 to filter out moisture and impurities, it enters the throttle 9, where the temperature and pressure of the liquid refrigerant decrease, and then enters the evaporator 10. In the evaporator 10, the low-temperature and low-pressure liquid refrigerant absorbs the heat of the outside air and evaporates, becoming a low-temperature and low-pressure gaseous refrigerant, which is then sucked into the compressor 6 for the next cycle.

[0027] The evaporator 10 acts as a source-side heat exchanger. When the temperature of the refrigeration chamber 11 is lower than a certain value, frost may form. At this time, the heating wire 15 may be turned on to generate heat, and the heat may be blown to the evaporator 10 through the blower fan 14 to remove the frost on the heat dissipation fins of the evaporator 10.

[0028] The water generated after defrosting is collected into the air supply channel 5 along the guide plate 13 and discharged through the drain port 16; during normal operation, the drain port 16 is in a blocked state to prevent the cold air from leaking out, and is opened again during defrosting.

[0029] like Figure 3 As shown, a plurality of air ducts 31 are arranged side by side along the length direction of the air supply bottom plate 3 , one end of the air duct 31 is connected to the air supply channel 5 , and an air outlet 32 ​​connected to the freezing chamber 12 is arranged at the top of the air duct 31 .

[0030] The cold air generated by the refrigeration system enters the air duct 31 through the air supply channel 5. When goods are piled above the air supply bottom plate 3, the air outlet 32 ​​there will be blocked by the goods, and the cold air will continue to be transported forward along the air duct 31 until it is discharged from the air outlet 32 ​​without being blocked by the goods. By setting up multiple air ducts 31 and air outlets 32, the air supply area is expanded, and the poor circulation of cold air caused by blocking of goods can be avoided to the greatest extent, thereby causing uneven freezing and quick freezing of goods, thereby improving the freezing efficiency of the container.

[0031] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
