[0002] With the improvement of people's living standards, the cooking skills and the processing of food materials are also pursued. For example, the meat is rapidly cooled to lock in moisture and nutrients, which is beneficial to its preservation. Therefore, the rapid cooling equipment is becoming more and more popular. For the rapid cooling equipment, under the condition that the basic refrigeration mode has no revolutionary technical conditions, the actual problem of how to transport the cooling capacity to the chamber for placing frozen objects needs to be solved.
[0003] The existing rapid cooling equipment mainly includes two categories of superconductor technology and compression refrigeration technology. Among them, due to the performance constraints of superconductor technology, it is not easy to achieve rapid cooling of a large amount of heat fluid, so the rapid cooling equipment using compression refrigeration technology is more popular.
[0004] The traditional compression refrigeration technology refers to setting a compressor in the rapid cooling equipment to connect the chamber for placing frozen objects through a cold pipe. The refrigerant is used as a cooling capacity carrier to achieve rapid cooling of the frozen objects in the chamber in an indirect freezing manner. However, the refrigerant is a high-pressure liquid, and a high-pressure freezing pipeline needs to be set for transmission. This means that the larger the volume of the rapid cooling equipment, the greater the distance between the compressor and the chamber for placing frozen objects. At present, the solution is to increase the length of the high-pressure cold pipe, but the longer the length of the cold pipe, the more difficult and costly the processing will be. If the pipeline leaks, the leaked refrigerant will cause harm to the equipment and the human body, and the risk is high. SUMMARY

[0064] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear, the present application will be further described in detail below in combination with the figures and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0065] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0067] In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.
[0068] In common commercial rapid cooling equipment, the traditional industry relies on compression technology for refrigeration, which is a way of refrigeration by transferring heat, and is currently known as a relatively efficient way of refrigeration, with a refrigeration efficiency of more than 2 times. But this scheme needs a closed and high-pressure-resistant pipeline system, which is generally extended directly to the chamber for placing the frozen objects; or, through the wind generated by the fan rotation, the cold quantity is blown to the chamber for placing the frozen objects through the closed air duct. At present, both of the above-mentioned schemes have relatively high technical difficulty, and the cold quantity transmission effect is not good.
[0069] For the scheme of extending the cold pipe, the refrigeration pipe is directly extended to the target, which means that the length of the pipeline needs to be increased. However, the high-pressure gas and liquid coexisting refrigerant flows in the pipeline, which has very high requirements for the sealing and strength of the pipeline, and also needs to weld the pipeline branch joint to prevent refrigerant leakage from causing harm. In this scheme, the compression refrigeration method will keep the refrigerant in a high-temperature and high-pressure environment, and once leakage occurs, the entire refrigeration system will be damaged. Therefore, the internal pipeline operation requirements and the welding requirements of the pipeline of the refrigeration system are high, and the processing difficulty is great.
[0070] For the scheme of using wind to blow cold, the cold generated in the rapid cooling device is transmitted by the wind generated by the fan rotation. A wind duct system with sufficient sealing needs to be designed. The entire wind duct system occupies a large internal space of the device. At the same time, the wind duct system also needs to be able to withstand high pressure and high temperature conditions generated during foaming of the device insulation layer. It can be seen that this scheme needs to be treated strictly in terms of insulation, sealing, strength, and sealing docking of the wind duct system in order to minimize the loss of cold air during transmission. Due to the use of compression refrigeration, the carrier of cold can be regarded as a gaseous substance. Due to the small specific heat and small heat carried per unit volume of the gaseous substance, these problems will restrict the rapid and large transmission of cold. If a large amount of cold is required, a large enough refrigeration system needs to be designed to meet the requirements, which means higher cost and lower system reliability.
[0071] In view of the above situation, the applicant has designed a new type of rapid cooling device after careful research. A normal pressure risk-free fluid is used as a cold carrier. The fluid has the advantages of large specific heat, small pressure required during flow, no impact on the refrigeration system after leakage, and the use of environmentally friendly liquid can prevent environmental pollution. The cold is stored in the fluid, and a large amount of cold is quickly and safely transmitted to the target requiring cold through the flow of the fluid, so as to take out the heat in the target and circulate, and finally realize the rapid reduction of the temperature of the target. The problems of high processing requirements for pipelines and high pressure in the traditional compression refrigeration mode, and the risk of refrigerant leakage are effectively solved. The specific scheme of the present application is described in detail below.
[0072] Please refer to Figure 1 and Figure 2 The rapid cooling device provided by the embodiments of the present application at least includes a first liquid storage container 1, a compressor 2, and a carrier container 3.
[0073] The carrier container 3 is used to place the frozen objects. The carrier container 3 can be a disc body on which the frozen objects can be placed directly. Alternatively, it is a fully enclosed box body in which the frozen objects are accommodated. Alternatively, it is a grid body specially set according to the use requirement or a mold for manufacturing a specific shape of frozen product, such as an ice cream mold or a jelly mold. The carrier container 3 can be independently set or set on a carrier, such as an internal chamber of a refrigerator, which is not limited here.
[0074] The first liquid storage container 1 is used to fill the fluid. The fluid can be preferably a liquid that does not freeze in the refrigeration temperature range of the rapid cooling device. The liquid is used as a cold carrier, and there is no risk even if the liquid leaks, which is safe and reliable. For example, the fluid can use a glycol mixture. Such liquid can meet the requirement of not freezing at-60 degrees.
[0075] The first liquid storage container 1 is connected with an inlet and outlet pipeline 4, which contains the pipeline for output and input of the first liquid storage container 1, and the inlet and outlet pipeline 4 is used to form a closed circulation flow channel passing through the object container 3 and conveying fluid. The first liquid storage container 1 is connected to the object container 3 through the inlet and outlet pipeline 4 and constitutes a closed circulation flow channel for conveying fluid. In this way, the fluid in the first liquid storage container 1 can flow in the circulation flow channel, take away the heat of the frozen object on the object container 3 and circulate, so as to quickly reduce the temperature of the frozen object placed on the object container 3.
[0076] The compressor 2 is connected to the first liquid storage container 1 through the cold pipe 21 and refrigerates the fluid in the first liquid storage container 1. That is, the output part of the compressor 2 in the conventional refrigeration device is directly connected to the first liquid storage container 1, and the fluid in the first liquid storage container 1 is refrigerated to keep the fluid in the first liquid storage container 1 at a low temperature, and then the low-temperature fluid is conveyed to the object container 3 as a cold carrier to take away the heat of the frozen object on the object container 3 and circulate to transmit cold to the object container 3, so as to quickly reduce the temperature of the frozen object.
[0077] Compared with the prior art, the rapid cooling device provided by the embodiment of the application is used to convey the liquid substance storing cold to the object container 3 in need of cold through a pipeline, so as to realize the temperature reduction of the frozen object.
[0078] Compared with the conventional method of directly conveying refrigerant, the refrigerant is a high-pressure liquid substance, needs to be transmitted in a high-pressure pipeline, and has high requirements for the pipeline. Once leakage occurs, the refrigerant will cause pollution risk. The cold transmission fluid of the application is a low-pressure liquid substance, is safe, and can be used for cold transmission in a low-pressure pipeline. Even if the low-pressure liquid substance leaks locally in the low-pressure pipeline, it will not cause great harm to the human body and the refrigeration system in the equipment.
[0079] Compared with the method of blowing cold in the related art, the cold transmission fluid of the application is a low-pressure liquid substance, has large specific heat and large heat carried per unit volume, needs small pressure in the flowing process, is conducive to rapid and large cold transmission, eliminates the high requirements of the heat preservation, sealing, strength, and sealing docking of the air duct system, effectively reduces the design difficulty of the internal refrigeration system of the equipment, is safe and reliable, and is conducive to reducing the production cost.
[0080] The quick cooling device of the present application, although the cold quantity of the traditional refrigeration scheme is exchanged twice, but the cold quantity exchange can be carried out inside the insulation layer of the quick cooling device. According to the law of conservation of cold quantity, the actual refrigeration quantity does not leak to the external environment of the device, and therefore has no effect on the energy consumption of the quick cooling device. When the secondary cold quantity exchange is increased, liquid, non-toxic and reliable substances (substances in liquid state at-18 degrees or lower temperature, such as glycol solution, salt water solution, organic solution, alcohol, etc. can be used as fluid) are used. The specific heat of such liquid substances as fluid is more than several tens of times that of traditional refrigerants. These fluids exchange heat with the cold pipes 21 inside the first liquid storage container 1, so that the fluid in the first liquid storage container 1 of the present application can be used as an energy storage substance, which is beneficial to slow down the temperature fluctuation in the quick cooling device, reduce the frequent start of the compressor 2, and reduce the energy consumption.
[0081] In addition, the fluid in the first liquid storage container 1 can also be used as a backup cold quantity, especially when the power is off, the quick cooling device can still be used for a certain period of time, greatly extending the low temperature environment inside the quick cooling device.
[0082] Preferably, in the quick cooling device provided by the embodiment of the present application, referring to Figure 2 , the inlet and outlet pipe 4 connected to the first liquid storage container 1 can be preferably a flexible hose that can be bent or deformed as a whole or in part.
[0083] Since the cold quantity carrier used in the present application is a low-pressure liquid substance, high-pressure pipes are not required for transmission, so that low-pressure liquid substances can be transmitted in low-pressure pipes. The low-pressure pipes can use the above-mentioned flexible hose, and can preferably use a common bellows, etc. The extension and deformation function of the bellows can realize the twisting and rotation of the pipe within a certain rotation angle range. It is beneficial to solve the problem of long-distance transportation of cold quantity, or to transport cold quantity in a relatively complex environment (such as sending cold quantity to the door body of the quick cooling device, which needs to overcome the rotating motion of the door body, etc.), effectively improving the adaptability of the inlet and outlet pipe 4 to the use environment.
[0084] For the setting mode of the inlet and outlet pipe 4 on the carrier container 3
[0085] In the quick cooling device of the present application, how to quickly transfer the fluid carrying cold quantity to the carrier container 3 is particularly important for quickly freezing the frozen objects placed on the carrier container 3. Therefore, how to quickly and maximally exchange heat between the fluid in the inlet and outlet pipe 4 and the carrier container 3 is particularly crucial for the setting mode of the inlet and outlet pipe 4 on the carrier container 3.
[0086] Therefore, in the quick cooling device of the present application, the setting mode of the inlet and outlet pipe 4 on the carrier container 3 includes but is not limited to the following forms:
[0087] Embodiment one
[0088] In one embodiment of the present application, referring to Figure 3 , the part of the inlet and outlet pipeline 4 located on the object container 3 is laid on the outer surface of the object container 3, which is simple in structure and easy to process and form, effectively reducing the production difficulty. The inlet and outlet pipeline 4 directly contacts the object container 3, quickly freezes the frozen objects placed on the object container 3, and effectively improves the freezing speed.
[0089] In this embodiment, the inlet and outlet pipeline 4 can be preferably laid on the bottom surface of the object container 3; and the part of the inlet and outlet pipeline 4 located on the bottom surface of the object container 3 can be preferably arranged in a serpentine shape, which is beneficial to cover the entire bottom surface of the object container 3, thereby improving the range and uniformity of cold energy transmission.
[0090] Preferably, on the basis of the above, as shown in Figure 4 , the outer surface of the object container 3 has a limiting groove 31, and the part of the inlet and outlet pipeline 4 located on the object container 3 can be embedded in the limiting groove 31.
[0091] In this embodiment, the limiting groove 31 on the outer surface of the object container 3 can be preferably set in a shape that matches the arrangement mode of the inlet and outlet pipeline 4, and can be preferably set in a serpentine groove track to embed the inlet and outlet pipeline 4 in the limiting groove 31, effectively ensuring the fixing effect of the inlet and outlet pipeline 4 and avoiding easy displacement of the inlet and outlet pipeline 4.
[0092] In addition, the inlet and outlet pipeline 4 is embedded in the limiting groove 31 on the outer surface of the object container 3, and the two side groove walls of the limiting groove 31 surround the outer periphery of the inlet and outlet pipeline 4, which is beneficial to reduce the outward diffusion of cold energy on the inlet and outlet pipeline 4. Therefore, the groove structure of the limiting groove 31 is beneficial to reduce the loss of cold energy on the inlet and outlet pipeline 4 and improve the concentration of cold energy emitted on the inlet and outlet pipeline 4.
[0093] Embodiment Two
[0094] For the arrangement mode of the inlet and outlet pipeline 4 on the object container 3, in the second embodiment of the present application, referring to Figure 5 , the part of the inlet and outlet pipeline 4 located on the object container 3 penetrates into the inside of the object container 3.
[0095] In this embodiment, a partition layer can be provided inside the object container 3, so that the inside of the object container 3 is divided into an upper chamber and a lower chamber, the upper chamber is used to place frozen objects, and the lower chamber is used to accommodate the inlet and outlet pipeline 4.
[0096] Preferably, the inlet and outlet pipe 4 is arranged in a serpentine shape inside the object container 3, and can specifically enter the inner cavity of the object container 3 from one end of the object container 3, then be arranged in a serpentine shape and extend to the other end of the object container 3, and then exit the outer portion of the object container 3 from the other end of the object container 3. In this way, the internal space of the object container 3 is maximally covered, and the efficiency and uniformity of the cold quantity transmission are improved.
[0097] Compared with the above-mentioned manner of laying on the outer surface of the object container 3, at least part of the inlet and outlet pipe 4 is located inside the object container 3 in the embodiment, so that the cold quantity on the part of the inlet and outlet pipe 4 is diffused inside the object container 3, and the frozen objects placed on the object container 3 are concentratedly frozen, and the efficiency of the rapid cooling is effectively improved.
[0098] Embodiment three
[0099] For the above-mentioned two setting modes of the inlet and outlet pipe 4, due to the limitation of the laying shape of the inlet and outlet pipe 4 on the object container 3, the cold quantity transmission effect is better at the part of the pipe body of the inlet and outlet pipe 4 in contact with the object container 3, and the cold quantity transmission effect is poor at the remaining part of the pipe body not in contact, which affects the uniformity of the cold receiving of the frozen objects placed on the object container 3.
[0100] In this regard, in the third embodiment of the present application, please refer to Figure 6 The rapid cooling device further comprises a second liquid storage container 32 filled with the above-mentioned cold carrying fluid, the object container 3 is arranged on the second liquid storage container 32, the inlet and outlet pipe 4 is in communication with the inside of the second liquid storage container 32, and the cold quantity is transmitted to the object container 3 by using the second liquid storage container 32.
[0101] In this way, the second liquid storage container 32 is used as a cold quantity transmission carrier between the object container 3 in the embodiment, and the cold quantity transmission uniformity and the cold quantity temperature uniformity are improved by using the second liquid storage container 32 in contact with the object container 3. The cold receiving range of the frozen objects placed on the object container 3 is larger and more uniform, the cold receiving temperature is uniform, and the rapid cooling effect is improved.
[0102] For the connection mode between the second liquid storage container 32 and the object container 3. In one embodiment, the object container 3 is preferably detachably arranged on the second liquid storage container 32, which is beneficial to loading the frozen objects into or taking out the rapid cooling device. In another embodiment, the object container 3 can also be preferably integrally connected to the second liquid storage container 32, so as to improve the tightness of the mutual contact between the two, and effectively improve the cold quantity transmission efficiency.
[0103] Embodiment four
[0104] For the setting mode of the inlet and outlet pipe 4 on the carrier container 3, in the fourth embodiment of the present application, please refer to Figure 6 The difference from the third embodiment is that the inlet and outlet pipe 4 penetrates into the interior of the second liquid storage container 32, and the part of the inlet and outlet pipe 4 in the interior of the second liquid storage container 32 is in contact with the fluid in the second liquid storage container 32.
[0105] In this way, the inlet and outlet pipe 4 exchanges heat with the fluid in the second liquid storage container 32, and then the second liquid storage container 32 is used as a cold output carrier to uniformly transfer cold to the carrier container 3 to rapidly cool the frozen objects, effectively ensuring the uniformity of cold transfer and the uniformity of cold temperature.
[0106] In the present embodiment, the second liquid storage container 32 is equivalent to another independent fluid-loaded container, so that the second liquid storage container 32 forms a cold storage carrier arranged on the carrier container 3, which is beneficial to store cold, so as to maintain the output of cold to the carrier container 3 in special situations such as power failure or shutdown due to operation settings, thereby prolonging the low-temperature environment on the carrier container 3 and effectively expanding the performance of the rapid cooling device.
[0107] For the specific structure of the inlet and outlet pipe 4 connected to the first liquid storage container 1
[0108] In an embodiment of the present application, please refer to Figure 7 The inlet and outlet pipe 4 on the first liquid storage container 1 includes an input pipe 41 and an output pipe 42 connected between the first liquid storage container 1 and the carrier container 3, respectively. The output pipe 42 is connected to the bottom of the first liquid storage container 1, and the input pipe 41 can access the interior of the first liquid storage container 1 from a part other than the bottom of the first liquid storage container 1.
[0109] In the present embodiment, the first liquid storage container 1 can be preferably a rectangular box, and the first liquid storage container 1 has at least a top surface and a bottom surface, as well as four side surfaces. The input pipe 41 is preferably connected to the top surface of the first liquid storage container 1 and accesses the interior of the first liquid storage container 1 from the top of the first liquid storage container 1. The output pipe 42 is connected to the bottom surface of the first liquid storage container 1 and communicates with the bottom outlet of the first liquid storage container 1.
[0110] In this way, the fluid in the first liquid storage container 1 can be output from the bottom of the first liquid storage container 1 and reach the carrier container 3, and then return to the interior of the first liquid storage container 1 from the top of the first liquid storage container 1, thereby forming a closed circulation flow channel. The fluid in the interior of the first liquid storage container 1 is maximally utilized for cold transfer, thereby improving the utilization rate of the fluid in the interior of the first liquid storage container 1.
[0111] In other embodiments (not shown), the input pipe 41 can also be connected to the side of the first liquid storage container 1, and can be preferably connected to any one side near the top surface of the first liquid storage container 1. In this way, it is beneficial to adapt the installation environment of the first liquid storage container 1, and thus facilitate the setting of the input and output pipes 4 on the first liquid storage container 1, effectively improving the flexibility of setting the connecting pipes on the first liquid storage container 1.
[0112] In order to improve the flow rate of cold energy transmission and overcome the pressure difference between high and low positions, in an embodiment of the present application, referring to Figure 7 , the first liquid storage container 1 is also connected to a pump body 5, and the pump body 5 is connected to the input and output pipes 4.
[0113] Preferably, the pump body 5 can be a water pump with a small volume and a power requirement, which provides power for the fluid in the first liquid storage container 1, and is beneficial to control the flow rate of the fluid and improve the cold energy transmission efficiency of the entire refrigeration system.
[0114] Preferably, the pump body 5 can be preferably arranged at the bottom of the first liquid storage container 1, and specifically, the height of the pump body 5 can be lower than the bottom of the first liquid storage container 1, so that the pump body 5 is arranged on the output pipe 42.
[0115] In this way, in combination with the return of the fluid from the top of the first liquid storage container 1, the pump body 5 is arranged at the bottom of the first liquid storage container 1, and the pump body 5 is used to extract the refrigerated fluid after heat exchange in the first liquid storage container 1 from the bottom of the first liquid storage container 1 and transmit it to the object container 3 for cooling again and form a cycle, effectively maintaining the circulation and transmission speed of the cold energy transmission, and thus improving the rapid cooling efficiency of the equipment.
[0116] For the setting mode of the cold pipe 21 connected to the first liquid storage container 1
[0117] In the rapid cooling equipment of the present application, how to quickly make the fluid in the first liquid storage container 1 reach the freezing temperature is particularly important for cold energy transmission. For the temperature of the fluid in the first liquid storage container 1, the cold pipe 21 connected to the first liquid storage container 1 by the compressor 2 is used to quickly transfer cold energy to the fluid in the first liquid storage container 1. Therefore, how to quickly and maximally make the fluid in the first liquid storage container 1 exchange heat with the cold pipe 21 so that the fluid can meet the freezing temperature and be transmitted to the object container 3 is particularly crucial for the setting of the cold pipe 21 on the first liquid storage container 1.
[0118] Therefore, in the rapid cooling equipment of the present application, the setting mode of the cold pipe 21 connected to the first liquid storage container 1 includes but is not limited to the following forms:
[0119] In an embodiment of the present application, referring to Figure 8The cold pipe 21 is inserted into the inner cavity of the first liquid storage container 1, and preferably covers the entire inner cavity of the first liquid storage container 1, which is equivalent to immersing the cold pipe 21 in the fluid, so that the part of the cold pipe 21 in the inner cavity of the first liquid storage container 1 is in direct contact with the fluid, effectively improving the heat exchange efficiency and further improving the refrigeration effect on the fluid.
[0120] In another embodiment of the present application, referring to Figure 9 The cold pipe 21 is connected to the outside of the first liquid storage container 1, and specifically can be laid on the outer surface of the first liquid storage container 1. The fluid in the first liquid storage container 1 exchanges heat with the cold pipe 21 laid on the outer surface of the first liquid storage container 1 through the wall of the first liquid storage container 1, ensuring the refrigeration effect on the fluid.
[0121] Compared with the above-mentioned method of inserting the cold pipe 21 into the inside of the first liquid storage container 1, the above-mentioned scheme needs to insert the cold pipe 21 into the inside of the first liquid storage container 1, and the insertion part needs to be sealed, otherwise it will be easy to cause liquid leakage. In this embodiment, the cold pipe 21 is laid on the outer surface of the first liquid storage container 1, which can be fixed on the outer surface of the first liquid storage container 1 by welding or other methods, which is conducive to reducing the difficulty of setting the cold pipe 21 on the first liquid storage container 1. Since the first liquid storage container 1 does not need to be inserted, the integrity and sealing of the first liquid storage container 1 can be ensured, effectively eliminating the risk of liquid leakage.
[0122] For the overall structure of the rapid cooling device
[0123] In one embodiment of the present application (not shown in the figure), a plurality of groups of inlet and outlet pipes 4 are connected to the first liquid storage container 1, and the plurality of groups of inlet and outlet pipes 4 are respectively connected to a plurality of object carrying containers 3.
[0124] In this way, the fluid in the first liquid storage container 1 is used to transfer cold energy to each object carrying container 3 on the rapid cooling device, which is conducive to batch rapid cooling of the frozen objects, and further improves the working efficiency of the device.
[0125] Based on the above, the first liquid storage container 1 is also preferably connected with a control valve (not shown in the figure), which is used to control the opening and closing of each group of inlet and outlet pipes 4.
[0126] The control valve is used to start and stop the cooling of each object carrying container 3 on the rapid cooling device, which further improves the controllability of the cold energy transmission and effectively improves the performance of the refrigeration system in the device.
