This involves controlling the compressor's start-up and shutdown based on the refrigerator compartment temperature. However, in low ambient temperatures, the refrigerator compartment easily reaches its target temperature. This control method results in a short compressor operating time; the compressor shuts down before the freezer compartment reaches its target temperature, making it difficult to meet the freezer compartment's temperature requirements.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This application proposes a refrigeration device, such as Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of an embodiment of the refrigeration equipment of this application; Figure 2 yes Figure 1 Disassembly diagram of the internal structure of the refrigeration equipment; Figure 3 yes Figure 1 A schematic diagram of the structure of the refrigeration equipment body. The refrigeration equipment 100 includes: a body 10, a cold storage component 20, and a refrigeration mechanism 30; wherein, the body 10 includes an outer shell 11 and an inner liner 12, the inner liner 12 forming a freezer compartment 121 and a refrigerator compartment 122; the cold storage component 20 is disposed near the freezer compartment 121 and is used to cool the freezer compartment 121; the evaporator 31 of the refrigeration mechanism 30 is disposed between the inner liner 12 and the outer shell 11 and is used to directly cool the freezer compartment 121 and the refrigerator compartment 122.

[0022] The outer shell 11 is used to protect and cover the internal components of the refrigeration equipment 100; the inner liner 12 forms a freezer compartment 121 and a refrigerator compartment 122 to meet storage needs.

[0023] The operating temperature of the freezer compartment 121 is lower than that of the refrigerator compartment 122 to meet the storage needs of different items; the cold storage component 20 is located close to the freezer compartment 121 so that the cold storage component 20 can directly cool the freezer compartment 121.

[0024] The refrigeration equipment 100 in this embodiment is a direct cooling equipment, which does not require the installation of components such as air ducts. It directly transfers the cooling capacity to the freezer compartment 121 and the refrigerator compartment 122 through the evaporator 31.

[0025] In this application, the evaporator 31 of the refrigeration unit 30 directly refrigerates the freezer compartment 121 and the refrigerator compartment 122. This means that, unlike the air-cooled refrigeration equipment 100 which uses a fan to blow cold air into the freezer compartment 121 and the refrigerator compartment 122 through an air duct, the evaporator 31 in the refrigeration equipment 100 of this application directly contacts the outer surfaces of the freezer compartment 121 and the refrigerator compartment 122 respectively, so that the evaporator 31 can directly exchange heat with the freezer compartment 121 and the refrigerator compartment 122 respectively, thereby improving the refrigeration efficiency of the evaporator 31.

[0026] In this embodiment, the refrigeration device 100 includes a refrigeration mechanism 30, a freezer compartment 121, a refrigerator compartment 122, and a cold storage component 20. The cold storage component 20 is located close to the freezer compartment 121 and is used to cool the freezer compartment 121. When the refrigeration mechanism 30 is running, the evaporator 31 of the refrigeration mechanism 30 directly cools the freezer compartment 121 and the refrigerator compartment 122, and also cools the cold storage component 20. Because of the presence of the cold storage component 20, the cooling capacity provided by the compressor is distributed to the cold storage component 20, which increases the time it takes for the refrigerator compartment 122 to reach the target temperature. This prolongs the cooling time of the refrigeration device 100 in low-temperature environments, preventing the problem that the compressor's running time is too short in low-temperature environments, and the temperature of the freezer compartment 121 has not yet dropped to its target temperature. The longer cooling time further makes the temperature of the freezer compartment 121 as close as possible to or reach the target temperature. When the refrigeration mechanism 30 stops running, the cold storage component 20 is used to cool the freezer compartment 121. In this way, the present application can store cold through the cold storage component 20 when the refrigeration mechanism 30 is running, and cool the freezer compartment 121 when the refrigeration mechanism 30 is not running, which can at least solve the problem of poor cooling effect of the freezer compartment 121 under low temperature environment and improve the cooling effect of the freezer compartment 121.

[0027] In some embodiments, such as Figure 1 and Figure 2 As shown, the evaporator 31 includes a refrigeration evaporator 311, which is located outside the freezer compartment 121 and is used to directly cool the freezer compartment 121; the cold storage component 20 is located close to the refrigeration evaporator 311, and the refrigeration evaporator 311 is also used to store cold for the cold storage component 20.

[0028] The evaporator 311 is located outside the freezer compartment 121 and is in direct contact with the outer surface of the freezer compartment 121, so that the evaporator 311 and the freezer compartment 121 can directly exchange heat, thereby improving the refrigeration efficiency of the evaporator 311; the cold storage component 20 is located close to the evaporator 311 so as to achieve cold storage by exchanging heat with the evaporator 311.

[0029] In some embodiments, such as Figure 1 and Figure 2 As shown, the evaporator 311 is arranged around at least the two sides and the top of the freezer compartment 121; the cold storage assembly 20 is located at the top of the freezer compartment 121.

[0030] like Figure 1 and Figure 2 As shown, the evaporator 311 is arranged around the left and right sides and top of the freezer chamber 121 to increase the contact area between the evaporator 311 and the outer surface of the freezer chamber 121, thereby improving the heat exchange efficiency and cooling speed, and thus improving the cooling effect. The cold storage component 20 is located at the top of the freezer chamber 121 to utilize the characteristic that cold air moves downwards due to its high density, thereby improving the cooling efficiency. In this way, the cooling uniformity can be improved (compared to when the cold storage component 20 is located on the side of the freezer chamber 121), thus improving the cooling effect.

[0031] In other embodiments, in order to improve the cooling effect of the evaporator 311 on the freezer chamber 121, the evaporator 311 can be arranged around the sides, top and bottom of the freezer chamber 121.

[0032] In some embodiments, such as Figure 1 and Figure 2 As shown, the cold storage assembly 20 includes a cold storage bag 21, which is attached between two adjacent evaporation tubes (not shown) of the freezer evaporator 311 and is in contact with the top of the freezer compartment 121.

[0033] The cold storage bag 21 is attached between two adjacent evaporator tubes of the refrigeration evaporator 311, meaning that the cold storage bag 21 is placed close to the two adjacent evaporator tubes to improve the efficiency of heat exchange between the cold storage bag 21 and the refrigeration evaporator 311, thereby improving the cold storage efficiency; the cold storage bag 21 is placed in contact with the top of the freezer compartment 121 to improve the efficiency of heat exchange between the cold storage bag 21 and the freezer compartment 121, thereby improving the refrigeration efficiency of the cold storage bag 21.

[0034] By using the cold storage bag 21 to store cold energy when the refrigeration mechanism 30 is running, and to cool the freezer compartment 121 when the refrigeration mechanism 30 is not running, the refrigeration effect and equipment reliability can be improved without increasing the power or complex structure. The cost is low and the structure is simple.

[0035] One cold storage bag 21 can be installed at the top of the freezer compartment 121; or two, three, four or more cold storage bags 21 can be installed at the top of the freezer compartment 121 to improve the cold storage capacity and cooling capacity of the cold storage component 20, and improve the uniformity of cooling.

[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, the evaporator 31 includes a refrigeration evaporator 312, which is located at the back of the refrigeration compartment 122 and is used to directly cool the refrigeration compartment 122.

[0037] The refrigeration evaporator 312 is located at the back of the refrigeration compartment 122 and is in direct contact with the outer surface of the refrigeration compartment 122, so that the refrigeration evaporator 312 and the refrigeration compartment 122 can directly exchange heat, thereby improving the refrigeration efficiency of the refrigeration evaporator 312.

[0038] The evaporator tube of the refrigeration evaporator 312 is arranged in an "S" shape to increase the length of the evaporator tube, increase the contact area between the refrigeration evaporator 312 and the outer surface of the refrigeration compartment 122, improve the efficiency of heat exchange between the two, and improve the refrigeration efficiency of the refrigeration evaporator 312.

[0039] In use, the refrigeration device 100 is positioned vertically with its top above its bottom, its front facing the user, its back facing away from the front, and its side connecting the back and the front.

[0040] In some embodiments, such as Figures 1 to 3 As shown, the freezer compartment 121 and the refrigerator compartment 122 are arranged vertically, with the freezer compartment 121 located above the refrigerator compartment 122.

[0041] The freezer compartment 121 and the refrigerator compartment 122 are arranged vertically to save the floor space of the refrigeration equipment 100. The freezer compartment 121 is located above the refrigerator compartment 122 so that cold air can flow naturally to the refrigerator compartment 122, improving energy efficiency, simplifying the layout of the refrigerator evaporator 312, reducing energy consumption, and saving costs.

[0042] In some embodiments, such as Figures 4 to 5 As shown, Figure 4 This is a disassembled schematic diagram of the internal structure of another embodiment of the refrigeration equipment of this application; Figure 5 yes Figure 4 A schematic diagram of the main body of the refrigeration equipment. The freezer compartment 121 and the refrigerator compartment 122 are arranged vertically, with the refrigerator compartment 122 located above the freezer compartment 121. Since users use the refrigerator compartment 122 much more frequently than the freezer compartment 121, placing the refrigerator compartment 122 on top allows users to easily retrieve or place items without frequently bending over, improving the convenience of the refrigeration equipment 100 and enhancing the user experience.

[0043] In some embodiments, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the internal connection and cold circulation of the refrigeration mechanism in the refrigeration equipment of this application. The refrigeration mechanism 30 also includes: a compressor (not shown in the figure), a condenser (not shown in the figure), a refrigeration evaporator 311 and a refrigeration evaporator 312, wherein the compressor, condenser, refrigeration evaporator 311 and refrigeration evaporator 312 are connected in sequence, and the refrigeration evaporator 312 is also connected to the compressor.

[0044] The compressor compresses the refrigerant gas into a high-temperature, high-pressure gas and discharges it into the condenser. The high-temperature, high-pressure gas exchanges heat with the outside environment in the condenser, releasing heat and liquefying. The high-pressure liquid is depressurized by a throttling valve (not shown in the figure) and becomes a low-pressure, low-temperature liquid. It then flows into the refrigeration evaporator 311 and the cold storage evaporator 312 in sequence, absorbs heat from the outside environment and evaporates into a gaseous state to achieve refrigeration. It then returns from the cold storage evaporator 312 to the compressor to complete the cycle.

[0045] The refrigerant coming out of the condenser has a strong cooling capacity (low temperature). It first passes through the refrigeration evaporator 311 to meet the high cooling demand of the refrigeration evaporator 311, and then passes through the refrigeration evaporator 312. In this way, the cooling capacity and cooling demand are matched, and energy efficiency is improved.

[0046] In some embodiments, such as Figure 7 As shown, Figure 7 This is a schematic diagram of a partial structure of another embodiment of the refrigeration equipment of this application. The refrigeration equipment 100 also includes: a temperature sensor 40 and a controller 50, wherein the temperature sensor 40 is disposed in the refrigerator compartment 122 and is used to sense the temperature of the refrigerator compartment 122; the controller 50 is connected to the compressor of the refrigeration mechanism 30 and the temperature sensor 40 respectively, and the controller 50 controls the compressor to work or stop working based on the temperature.

[0047] The temperature sensor 40 senses the temperature of the refrigerator compartment 122 and outputs the temperature information to the controller 50. The controller 50 is connected to both the compressor and the temperature sensor 40. The controller 50 receives the temperature information output by the temperature sensor 40 and controls the operating state of the compressor based on this information. In this way, the controller 50 can intelligently adjust the operating state of the compressor according to the temperature of the refrigerator compartment 122, such as controlling the compressor to start or stop, in order to achieve energy saving and consumption reduction.

[0048] In some embodiments, such as Figures 1 to 7 As shown, the controller 50 controls the compressor to stop working when the temperature is lower than the first temperature threshold; the cold storage component 20 includes a cold storage bag 21, the volume of cold storage liquid in the cold storage bag 21 is positively correlated with the first temperature threshold, and / or negatively correlated with the target temperature of the freezer compartment 121.

[0049] The controller 50 acquires the temperature of the refrigerator compartment 122 and determines the relationship between the temperature of the refrigerator compartment 122 and a preset first temperature threshold. If the temperature of the refrigerator compartment 122 is less than or equal to the first temperature threshold, it is determined that the temperature of the refrigerator compartment 122 has reached the target temperature, and the compressor is controlled to stop working to reduce energy consumption. If the temperature of the refrigerator compartment 122 is greater than the first temperature threshold, the compressor is controlled to work (the cooling demand of the refrigerator compartment 122 has not yet been met) to cool the refrigerator compartment 122, the freezer compartment 121, and the cold storage component 20.

[0050] Based on the control strategy of the controller 50, in a low-temperature environment, the refrigerator compartment 122 easily reaches its target temperature. The controller 50 then stops the compressor, and the evaporator 311 ceases cooling the refrigerator compartment 121. Because the compressor's operating time is short, the temperature of the refrigerator compartment 121 has not yet reached its target temperature. Due to the presence of the cold storage component 20, the cooling capacity provided by the compressor is distributed to the cold storage component 20, increasing the time it takes for the refrigerator compartment 122 to reach its target temperature. This extends the cooling time of the refrigeration equipment 100 in low-temperature environments, preventing the problem of the compressor's short operating time before the temperature of the refrigerator compartment 121 reaches its target temperature. The longer cooling time further brings the temperature of the refrigerator compartment 121 as close to or as close to the target temperature as possible. At this point, the cold storage bag 21 can continue to cool the refrigerator compartment 121, allowing it to reach its target temperature and improving its cooling effect. In this way, the original structure and control logic of the refrigeration equipment 100 can be maintained without altering the cold storage bag 21.

[0051] The cold storage component 20 includes a cold storage bag 21 containing a cold storage liquid. The cold storage liquid can absorb (cool) and release heat (cold storage) through its own phase changes. When the refrigeration mechanism 30 is running, the cold storage liquid transfers heat to the freezer evaporator 311 to achieve cold storage. When the refrigeration mechanism 30 stops running, the cold storage liquid absorbs heat from the freezer compartment 121, which can keep the temperature of the freezer compartment 121 stable for a considerable period of time, thus achieving cooling.

[0052] The volume of the cold storage liquid in the cold storage bag 21 is positively correlated with the first temperature threshold. The higher the first temperature threshold, the faster the compressor stops and the slower it restarts. The longer the compressor is in the shutdown state, the higher the requirements for the cold storage and cooling capacity of the cold storage component 20. Therefore, the volume of the cold storage liquid is required to be larger.

[0053] The volume of the cold storage liquid in the cold storage bag 21 is negatively correlated with the target temperature of the freezer 121. The lower the target temperature of the freezer 121, the higher the requirements for the cold storage and cooling capacity of the cold storage component 20, and therefore the larger the volume of the cold storage liquid is required.

[0054] In specific embodiments, the cold storage fluid can be water, saline hydrate, or a mixture of water and antifreeze.

[0055] In some embodiments, the cold storage assembly 20 includes a phase change cold storage material filled between the top of the freezer chamber 121 and the freezer evaporator 311.

[0056] Phase change energy storage materials (PCEs) are substances that can absorb or release large amounts of energy at specific temperatures through changes in their physical state (such as from solid to liquid or vice versa). They typically employ materials with strong thermal inertia to utilize their latent heat for energy storage. Thermal inertia refers to the rate of temperature change on the surface of a material when it is heated. During a phase change, the temperature of the PCE remains almost constant, but it absorbs or releases a large amount of heat (latent heat). When the refrigeration unit 30 is running, the temperature of the PCE decreases until it reaches its phase change temperature, at which point it releases a large amount of heat and undergoes a phase change, thus achieving energy storage. When the refrigeration unit 30 stops running, the temperature of the PCE slowly increases until it reaches its phase change temperature, at which point it absorbs a large amount of heat and undergoes a phase change, achieving refrigeration. This allows the temperature of the freezer compartment 121 to remain stable for a considerable period of time. In this way, phase change cold storage materials can be used to store cold while the refrigeration mechanism 30 is running, and to cool the freezer compartment 121 when the refrigeration mechanism 30 is not running. This achieves improved cooling effect and equipment reliability without increasing power, and realizes low-cost and high-efficiency temperature compensation.

[0057] The phase change cold storage material can be formulated with a specific phase change temperature according to the lower limit of the target temperature of the freezer chamber 121, so as to maintain the temperature of the freezer chamber 121 at the target temperature when the compressor stops. As an example, the phase change temperature of the selected phase change cold storage material is lower than the target temperature of the freezer chamber 121.

[0058] In some embodiments, the cold storage assembly 20 includes a cold storage unit (not shown) disposed on the top of the outer shell 11 of the freezer compartment 121 and above the freezer evaporator 311. The cold storage unit has a groove on the side facing the freezer compartment 121, and the freezer evaporator 311 is partially disposed in the groove. In this way, the contact area between the cold storage assembly 20 and the freezer evaporator 311 can be increased, the efficiency of heat exchange between the cold storage assembly 20 and the freezer evaporator 311 can be improved, and the cold storage efficiency and cold storage effect can be improved.

[0059] In some embodiments, a foam layer (not shown) is provided between the inner liner 12 and the outer shell 11. The foam layer is filled with foamed insulation material to slow down the heat exchange between the refrigerator compartment 122, the freezer compartment 121 and the outside, thereby reducing energy consumption.

[0060] Unlike existing technologies, the refrigeration device 100 proposed in this application includes a refrigeration mechanism 30, a freezer compartment 121, a refrigerator compartment 122, and a cold storage component 20. The cold storage component 20 is located close to the freezer compartment 121 and is used to cool the freezer compartment 121. When the refrigeration mechanism 30 is running, the evaporator 31 of the refrigeration mechanism 30 directly cools the freezer compartment 121 and the refrigerator compartment 122, and also cools the cold storage component 20. When the refrigeration mechanism 30 stops running, the cold storage component 20 is used to cool the freezer compartment 121. In this way, this application can store cold during the operation of the refrigeration mechanism 30 and cool the freezer compartment 121 when the refrigeration mechanism 30 stops running, which can at least solve the problem of poor cooling effect of the freezer compartment 121 under low temperature conditions and improve the cooling effect of the freezer compartment 121.

[0061] Furthermore, this application can improve the cooling effect and equipment reliability without increasing the power (because in the prior art, the environment where the temperature sensor is located needs to be heated by a heating element so that the temperature detected by the temperature sensor reaches the target temperature after a delay, thus delaying the compressor shutdown, and the heating element requires a large amount of power) and cost.

[0062] Furthermore, when the refrigeration mechanism 30 is running, in addition to cooling the refrigerator compartment 122 and the freezer compartment 121, it also cools the cold storage component 20. Therefore, the refrigeration mechanism 30 is in operation for a longer period of time, which can improve the problem that the low operating rate of the refrigeration mechanism 30 under low ambient temperature conditions makes it difficult for the temperature of the freezer compartment 121 to drop to the target temperature.
