[0070] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings 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.

[0071] It is to be noted that when an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element.

[0073] In addition, the terms "first", "second", are used only for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can include one or more of the features explicitly or implicitly. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0074] The conventional refrigeration scheme relying on compression technology in the industry is to cool by transferring heat, which is currently known as a relatively high-efficiency method, with a refrigeration efficiency of more than 2 times. However, this scheme requires a closed and high-pressure-resistant pipeline system. When a certain compartment inside the refrigerator needs cold, the refrigeration pipe is generally directly extended to the compartment; or the cold is blown to the compartment needing cold through the closed air duct by the rotation of the fan. At present, both of the above-mentioned schemes have relatively high technical difficulty, and the cold transmission effect is poor.

[0075] For the scheme of extending the cold pipe, the refrigeration pipe is directly extended to the target compartment, which means that the length of the pipeline needs to be increased. The pipeline flows with high-pressure gas and liquid coexisting refrigerant, which has 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 keeps the refrigerant in a high-temperature and high-pressure environment. 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 very high, especially when multiple compartments need to control different temperatures, more branch pipelines or air duct systems are needed to achieve, which further increases the processing difficulty, production defects and maintainability.

[0076] For the scheme of using wind to blow cold, the cold on the refrigerator evaporator is transmitted by the wind generated by the fan rotation, and a wind duct system with sufficient sealing performance needs to be designed. The entire system occupies a relatively large space inside the refrigerator, and a wind duct system is generally designed inside the foaming layer of the refrigerator. The wind duct system needs sufficient thickness of the thermal insulation layer to ensure that the wind duct has sufficient distance from the external environment, the internal different compartment temperature, the drain pipe and other systems for thermal insulation, so as to prevent icing, cold leakage and other risks in the wind duct, and affect the foaming expansion of the refrigerator. At the same time, the wind duct system also needs to withstand high pressure and high temperature conditions generated during the foaming of the refrigerator thermal insulation layer. It can be seen that this scheme needs to be strictly treated in terms of thermal insulation, sealing, strength, sealing and docking of the wind duct system, so as to minimize the loss of cold air in the transmission process. Since this scheme uses 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 requirement, which means higher cost and lower system reliability.

[0077] When it is necessary to transmit cold over a long distance or in a complex environment, it is difficult to use the above two schemes, and the actual cost is also relatively high.

[0078] Therefore, in view of the above situation, the applicant has designed a new type of cold transmission mechanism after careful research, broken the inherent thinking of the industry professionals (the inherent thinking refers to the traditional cold transmission scheme described above, such as extending the refrigerant-carrying refrigeration pipeline to the target compartment, or using the wind to transmit cold to the target compartment through the air duct), and creatively proposed a new type of cold transmission mechanism and a refrigerator with the cold transmission mechanism. A normal pressure and risk-free fluid is used as a cold carrier, the specific heat of the fluid is large, the pressure required during flow is small, the fluid leakage has no effect on the refrigeration system, the use of environmentally friendly liquid can also prevent environmental pollution, and other advantages. The cold is stored in the fluid, a large amount of cold is quickly and safely transmitted to the compartment that needs to be cooled through the flow of the fluid, so that the heat in the compartment is taken out and circulated, and finally the temperature of the compartment is quickly reduced. The problem of high requirements for pipeline, thermal insulation and high pressure in the traditional compression refrigeration scheme, as well as the risk of refrigerant leakage, is effectively solved. The scheme of the present application is described in detail as follows.

[0079] Please refer to Figure 1 The cold transmission mechanism provided by the embodiment of the present application at least includes a container 1 and a compressor 2.

[0080] The container 1 is used to fill fluid, which can be preferably a liquid that does not freeze in the refrigeration temperature range of the refrigerator, and the liquid is used as a cold carrier, and there is no risk even if the liquid leaks, and it is safe and reliable. For example, the fluid can adopt a glycol mixed liquid, and such a liquid can meet the requirement of not freezing at-60 degrees.

[0081] The container 1 is connected with an inlet and outlet pipeline 3, which contains an output and input pipeline on the container 1, and the inlet and outlet pipeline 3 is used to form a closed circulation flow channel through the cold transmission target 4 and transport the fluid. The container 1 is connected to the cold transmission target 4 through the inlet and outlet pipeline 3, and constitutes a closed circulation flow channel for transporting the fluid. Among them, the cold transmission target 4 can be a chamber for storing refrigerated objects, such as a chamber on the refrigerator; or a special vessel, etc. In this way, the fluid in the container 1 can flow in the circulation flow channel, take away the heat of the cold transmission target 4 and circulate, so as to quickly reduce the temperature of the cold transmission target 4.

[0082] The compressor 2 is connected to the container 1 through the cold pipe 21, and refrigerates the fluid in the container 1. That is, the output part of the compressor 2 in the conventional refrigeration device is directly connected to the container 1, and the fluid in the container 1 is refrigerated, so that the fluid in the container 1 is kept at a low temperature, and then the low-temperature fluid is transported to the cold transmission target 4 as a cold carrier to take away the heat of the cold transmission target 4, and circulate to transmit cold to the cold transmission target 4, so as to achieve the purpose of rapid cooling.

[0083] Compared with the prior art, the cold transmission mechanism provided by the embodiment of the application transmits cold through secondary exchange of cold, and transports the liquid substance storing cold to the target needing cold through a pipeline, so as to realize cooling.

[0084] Compared with the conventional method of directly transporting 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 transmit cold 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 of the refrigerator.

[0085] Compared with the method of blowing cold by air, 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 transmission of cold, eliminates high requirements for heat preservation, sealing, strength, and sealing docking of the air duct system, effectively reduces the design difficulty of the entire refrigeration system in the refrigerator, is safe and reliable, and is conducive to reducing production cost.

[0086] The cold quantity transmission mechanism 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 heat preservation layer of the refrigerator. According to the law of conservation of cold quantity, the actual refrigeration quantity does not leak to the outside environment of the refrigerator, so it has no effect on the energy consumption of the refrigerator. When the secondary cold quantity exchange is increased, liquid, non-toxic and reliable substances (-18 degrees or lower temperature in liquid state, such as: glycol solution, salt solution, organic solution, alcohol, etc.) are used. The specific heat of such liquid as a fluid is more than several tens of times that of traditional refrigerants. These fluids exchange heat with the cold pipe 21 inside the container 1, so that the fluid in the container 1 of the present application can be used as an energy storage material, as a refrigeration supplement of the refrigerator refrigeration system, which is beneficial to reduce the temperature fluctuation in the refrigerator compartment and reduce the frequent start of the compressor 2, thereby reducing the energy consumption.

[0087] In addition, the fluid in the container 1 can also be used as a backup cold quantity, especially when the power is off, the refrigerator can still be used for a certain period of time, which can quickly and effectively solve the environment that requires a large amount of cold quantity inside the refrigerator (for example: ice maker system, quick cooling area, refrigerator downtime caused by power failure or voltage instability, etc.), thereby greatly prolonging the low-temperature environment inside the refrigerator.

[0088] In actual application, the refrigeration system of the traditional refrigerator is generally designed in the box body part. When the cold quantity is needed on the movable door body, if the cold pipe carrying the refrigerant is used to directly transport the cold quantity to the door body, the synchronization of rotation and translation of the pipe during the movement of the door body needs to be solved. If the fan is used to transport the cold quantity from the box body to the door body, the sealing of the air duct system when the door body leaves the box body, the cold leakage, condensation, heat preservation and other problems of the air inlet and outlet need to be solved. At present, these problems have not been solved well.

[0089] Herein, in the cold quantity transmission mechanism provided in the embodiments of the present application, please refer to Figure 1 The inlet and outlet pipes 3 connected to the container 1 can be preferably flexible hoses that can be bent or deformed as a whole or in part.

[0090] Since the cold quantity carrier used in the present application is a low-pressure liquid substance, high-pressure pipes are not needed for transmission, so low-pressure liquid substances can be transmitted in low-pressure pipes. The low-pressure pipes can use the above-mentioned flexible hoses, which can realize the twisting and rotating of the pipes within a certain rotation angle range, which is beneficial to solve the problem of long-distance transportation of cold quantity or transportation of cold quantity in a complex environment (such as sending cold quantity to the door body of the refrigerator, which needs to overcome the rotating movement of the door body, etc.).

[0091] The flexible hose can preferably use a common bellows, which can meet the opening and closing of the door body between the body and the door body of the refrigerator.

[0092] Therefore, the cold energy transmission mechanism provided by the embodiment of the present application uses a low-pressure liquid to transmit cold energy, so that a conventional low-pressure hose such as a bellows can be used as a fluid transmission pipeline. The flexible deformation characteristics of the hose are used to flexibly adapt to the deformation of the whole or part caused by external force or the restriction of the environment, which is beneficial to flexibly setting the pipeline on the door body, door hinge or other special scenarios of the refrigerator, and effectively improves the environmental adaptability of the cold energy transmission mechanism.

[0093] For the specific structure of the inlet and outlet pipeline 3 connected to the container 1, in an embodiment of the present application, please refer to Figure 2 The inlet and outlet pipeline 3 on the container 1 includes an input pipe 31 and an output pipe 32 connected between the container 1 and the cold energy transmission target 4, respectively. The output pipe 32 is connected to the bottom of the container 1, and the input pipe 31 can access the inside of the container 1 from a part other than the bottom of the container 1.

[0094] In the embodiment, as shown in Figure 2 The container 1 can be preferably a rectangular box, and the container 1 has at least a top surface and a bottom surface, and four side surfaces. The input pipe 31 is connected to the top surface of the container 1 and accesses the inside of the container 1 from the top of the container 1. The output pipe 32 is connected to the bottom surface of the container 1 and communicates with the bottom output port of the container 1.

[0095] Therefore, the fluid in the container 1 can be output from the bottom of the container 1, and then returned to the inside of the container 1 from the top of the container 1 after reaching the cold energy transmission target 4, thereby forming a circulation. The fluid in the inside of the container 1 is maximally used for cold energy transmission, thereby improving the utilization rate of the fluid in the inside of the container 1.

[0096] In other embodiments (not shown in the figure), the input pipe 31 can also be connected to the side of the container 1, which can be preferably close to any one of the side surfaces of the top surface of the container 1. Therefore, it is beneficial to adapt to the installation environment of the container 1, thereby facilitating the setting of the inlet and outlet pipeline on the container 1, and effectively improving the flexibility of setting the connecting pipeline on the container 1.

[0097] 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, please refer to Figure 2 The container 1 is also connected with a pump body 5, and the pump body 5 is connected to the inlet and outlet pipeline 3.

[0098] The pump body 5 can be preferably a water pump with a small volume and meeting the power requirement. The pump body 5 provides flow force for the fluid in the container 1, which is beneficial to controlling the flow rate of the fluid and improving the cold energy transmission efficiency of the whole refrigeration system.

[0099] In the embodiment, please refer to Figure 1 andFigure 2 The output pipe 32 on the container 1 is connected to the bottom of the container 1, and the pump body 5 can be preferably arranged at the bottom of the container 1, and in particular, the height of the pump body 5 can be arranged lower than the bottom of the container 1, so that the pump body 5 is arranged on the output pipe 32.

[0100] In this way, the pump body 5 is arranged at the bottom of the container 1, and the pump body 5 is used to extract the refrigerated fluid in the container 1 after heat exchange from the bottom of the container 1 and transmit it to the cold energy transmission target 4 for cooling and forming a cycle, effectively maintaining the cycle and transmission speed of the cold energy transmission, and further improving the rapid cooling efficiency of the cold energy transmission target 4.

[0101] In the cold energy transmission mechanism of the present application, how to quickly make the fluid in the container 1 reach the freezing temperature is particularly important for cold energy transmission. For the temperature of the fluid in the container 1, the cold pipe 21 connected to the container 1 by the compressor 2 is used to quickly transfer cold energy to the fluid in the container 1. Therefore, how to quickly and maximally make the fluid in the container 1 exchange heat with the cold pipe 21 so that the fluid meets the freezing temperature and is transmitted to the cold energy transmission target 4 is particularly important for the arrangement of the cold pipe 21 on the container 1.

[0102] In this regard, in the cold energy transmission mechanism of the present application, the arrangement of the cold pipe 21 connected to the container 1 includes but is not limited to the following forms:

[0103] In an embodiment of the present application, please refer to Figure 3 The cold pipe 21 penetrates the inner cavity of the container 1 and preferably covers the entire inner cavity of the 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 container 1 is directly in contact with the fluid, effectively improving the heat exchange efficiency and further improving the freezing effect on the fluid.

[0104] In another embodiment of the present application, please refer to Figure 4 and Figure 5 The cold pipe 21 is connected to the outside of the container 1, and in particular, the part of the cold pipe 21 on the container 1 can be laid on the outer surface of the container 1, and the fluid in the container 1 exchanges heat with the cold pipe 21 laid on the outer surface of the container through the wall of the container, ensuring the freezing effect on the fluid.

[0105] Compared with the above-mentioned mode of penetrating the cold pipe 21 into the inside of the container 1, the above-mentioned scheme needs to penetrate the cold pipe 21 into the inside of the container 1 when the cold pipe 21 is arranged, and the penetration position needs to be sealed, otherwise liquid leakage will be easily caused. In the embodiment, the cold pipe 21 is laid on the outer surface of the container 1, and the cold pipe 21 can be fixed on the outer surface of the container 1 by welding or the like, which is beneficial to reduce the difficulty of arranging the cold pipe 21 on the container 1. Since the penetration treatment of the container 1 is not needed, the integrity and sealing of the container 1 can be ensured, and the risk of liquid leakage is effectively excluded.

[0106] For the cold pipe 21 arrangement forms in the above-mentioned two embodiments, the part of the cold pipe 21 on the container 1 can be arranged in a snake shape, so as to increase the coverage area of the cold pipe 21 on the container 1 and increase the contact area for heat exchange with the fluid, thereby effectively improving the heat exchange efficiency.

[0107] As an example, as shown in Figure 3 , the cold pipe 21 penetrating into the inside of the container 1 is arranged in a snake shape, and specifically, the cold pipe 21 can be penetrated into the inner cavity of the container 1 from the part close to the top of the container 1, then arranged in a snake shape from top to bottom in the inner cavity of the container 1, and penetrated out of the outside of the container 1 from the part close to the bottom of the container 1. In this way, the inside space of the container 1 is maximally covered, and the efficiency and uniformity of cold quantity transmission are improved.

[0108] As shown in Figure 5 , the cold pipe 21 laid on the outer surface of the container 1 can also be arranged in a snake shape, and specifically, the cold pipe 21 can be laid on the outer surface of one end face of the container 1 from one side of the container 1, then arranged in a snake shape on the outer surface of the container 1, and finally stretched out from the other side of the container 1. In this way, the one side end face of the container 1 is maximally covered, heat exchange is performed between the end face and the fluid in the inside of the container 1, and the efficiency and uniformity of cold quantity transmission are effectively improved.

[0109] For the above-mentioned arrangement of the cold pipe 21 on the outer surface of the container 1, the cold pipe 21 cannot directly contact the fluid, which affects the heat exchange efficiency between the fluid and the cold pipe 21.

[0110] Therefore, in an embodiment of the present application, referring to Figure 6 , the outer surface of the container 1 further has a positioning groove 11, and the part of the cold pipe 21 on the outer surface of the container 1 is embedded in the positioning groove 11.

[0111] In the embodiment, the positioning groove 11 is arranged in a shape matched with the cold pipe 21, and a snake-shaped groove track can be preferably adopted, so that the cold pipe 21 is embedded in the positioning groove 11, the fixing effect of the cold pipe 21 is effectively ensured, the cold pipe 21 is prevented from being easily displaced, and the high-pressure fixing strength of the cold pipe 21 is improved.

[0112] In addition, the cold pipe 21 is embedded in the positioning groove 11 on the outer surface of the container 1, and the groove wall of the positioning groove 11 surrounds the outer periphery of the cold pipe 21, which is beneficial to reduce the cold energy diffusion of the cold pipe 21. In this way, the groove structure of the positioning groove 11 reduces the loss of cold energy on the cold pipe 21 and improves the concentration of the cold energy emitted on the cold pipe 21.

[0113] Further, referring to Figure 6 , the end surface of the container 1 with the positioning groove 11 is recessed towards the inside of the container 1, so that the inside of the container 1 is formed with a convex rail (not shown in the figure) matched with the shape of the positioning groove 11, and the surface of the convex rail is in contact with the fluid in the inside of the container 1.

[0114] Specifically, in the present embodiment, the inside of the container 1 has a convex rail matched with the shape of the positioning groove 11, the cold pipe 21 is laid in the positioning groove 11, and the other side of the positioning groove 11 is the convex rail in the inside of the container 1. The surface of the convex rail is directly in contact with the fluid in the inside of the container 1, effectively increasing the contact area with the fluid, and further improving the heat exchange efficiency with the fluid.

[0115] Referring to Figure 7 , the present application provides a refrigerator, which comprises a box body and the cold energy transmission mechanism of the present application. The box body is configured with a chamber with a taking and placing opening. It can be understood that the refrigerator has various chambers for placing refrigerated objects. The inlet and outlet pipeline 3 on the container 1 is connected to the chamber to cool the chamber.

[0116] In this way, the cold energy transmission mechanism of the present application has a simple structure and occupies a small space, and can be used on a mobile refrigerator or a vehicle-mounted refrigerator. It is beneficial to meet the installation requirements of a refrigerator with a small volume, only a narrow space or a special-shaped installation environment (such as a special-shaped or narrow space on a vehicle where the vehicle-mounted refrigerator is located).

[0117] Referring to Figure 8 , the present application further provides another refrigerator, which comprises the cold energy transmission mechanism of the present application. The cold energy transmission mechanism further comprises an evaporator 6, which is arranged in the inside of the box body. It can be understood that the evaporator 6 is arranged in the inside of the refrigerator. The compressor 2 is connected to the evaporator 6, and the evaporator 6 is connected to the container 1 through the cold pipe 21. The refrigerator has a chamber 7 for placing refrigerated objects, and the inlet and outlet pipeline 3 on the container 1 is connected to the chamber 7.

[0118] In this way, the evaporator 6 increases the refrigeration capacity of the compressor 2 on the refrigerant, and then cools the fluid in the container 1, so as to meet the cold energy demand of a household refrigerator. The fluid in the container 1 exchanges heat with the cold pipe 21 with increased cold energy, so that the cold energy transmitted to the chamber 7 meets the freezing or refrigeration demand of a household refrigerator.

[0119] For the setting mode of the cold energy transmission mechanism in the household refrigerator, in an embodiment of the present application (not shown in the figure), the refrigerator has multiple compartments 7, and the container 1 is connected with multiple sets of inlet and outlet pipes 3, and the multiple sets of inlet and outlet pipes 3 are respectively connected to the multiple compartments 7.

[0120] In this way, the fluid in the container 1 is used to respectively transmit cold energy to the multiple compartments 7 of the refrigerator, and the cold energy transmission efficiency is effectively ensured. The fluid in the container 1 of the present application can be used as an energy storage material, as a refrigeration supplement of the refrigerator system, to slow down the temperature fluctuation of the compartments 7, and further reduce the frequent start of the compressor 2, thereby reducing the energy consumption of the refrigerator. The fluid in the container 1 can also be used as a backup cold energy, especially when the power is off, the refrigerator can still be used for a certain period of time, and the low-temperature environment inside the refrigerator can be greatly prolonged.

[0121] Further, in an embodiment of the present application, the container 1 is further connected with a control valve (not shown in the figure), and the control valve is used to respectively control the opening and closing of the multiple sets of inlet and outlet pipes 3.

[0122] In this way, the cooling supply to the multiple compartments 7 of the refrigerator is controlled to start and stop, and the controllability of the cold energy transmission is effectively improved, and the performance of the cold energy transmission system of the present application is improved.

[0123] Please refer to Figure 9 The embodiment of the present application also provides a third refrigerator, which comprises the cold energy transmission mechanism of the present application, and the cold energy transmission mechanism further comprises an evaporator 6, the compressor 2 is connected with the evaporator 6, and the evaporator 6 is connected with the container 1 through a cold pipe 21. The refrigerator has a door body 8, and the inlet and outlet pipes 3 on the container 1 are connected to the door body 8 of the refrigerator.

[0124] In this way, when it is needed to transport cold energy at a long distance or in a more complex environment, such as the door body 8 of the refrigerator which has a cold energy transmission requirement, the cold energy transmission mechanism of the present application is used to supply cold energy to the door body 8 which needs cold energy transmission, and the problems of cold leakage, condensation, heat preservation and the like of the traditional air duct system which needs to be sealed and has inlet and outlet air ports are effectively eliminated, and the applicability of the cold energy transmission mechanism of the present application is improved.

[0125] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
