Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to a cooling capacity compensation device and a refrigerator. Background Technology

[0002] In existing refrigerators, when the door is frequently opened or left open for extended periods, cold air escapes rapidly, while warm, humid outside air rushes in, causing the internal temperature to rise quickly and affecting food preservation. While traditional refrigeration systems can restart cooling after the door is closed, they require temperature detection before restarting the compressor, resulting in a delay in compressor response and limited cooling efficiency. This makes rapid cooling difficult, leading to significant temperature fluctuations within the refrigerator compartment, impacting user experience and food quality. Furthermore, the substantial loss of cold air during door opening results in energy waste as the refrigeration system continues to operate. Utility Model Content

[0006] The first opening is connected to the cold exchanger via a first air duct. The first opening is also fitted with a first partition component, which is used to block the flow of cold energy generated by the cold exchanger to the cold storage component.

[0007] The second opening is connected to the compartment via a second air duct. The second opening is also fitted with a second partition assembly, which is used to block the flow of cold energy from the cold storage assembly to the compartment.

[0008] Furthermore, the cold storage component includes:

[0009] The shell has a sealed chamber inside, which is filled with a phase change material for reversibly absorbing / releasing cold energy.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] When the present invention detects that the door of the corresponding compartment is open, the cold exchanger stops cooling the compartment and opens the first partition component so that the cold energy generated by the cold exchanger flows to the cold storage component, thereby effectively preserving the cold energy and reducing energy consumption during the door opening process. When the door of the corresponding compartment is closed, the cold exchanger resumes cooling the compartment, closes the first partition component, and opens the second partition component so that the cold storage component and the cold exchanger release the cold energy simultaneously and flow to the corresponding compartment. This increases the cooling rate after the door is closed, allowing the corresponding compartment to cool down quickly and return to the preset temperature, thus improving overall energy efficiency and user experience.

[0041] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0042] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0043] In existing refrigerators, when the door is frequently opened or left open for extended periods, cold air escapes rapidly, while warm, humid outside air rushes in, causing the internal temperature to rise quickly and affecting food preservation. While traditional refrigeration systems can restart cooling after the door is closed, they require temperature detection before restarting the compressor, resulting in a delay in compressor response and limited cooling efficiency. This makes rapid cooling difficult, leading to significant temperature fluctuations within the refrigerator compartment, impacting user experience and food quality. Furthermore, the substantial loss of cold air during door opening results in energy waste as the refrigeration system continues to operate.

[0044] Therefore, in some embodiments, such as Figure 1 As shown, this utility model provides a cold energy compensation device that can effectively retain cold energy during door opening and quickly restore temperature after door closing, including a refrigeration system containing a cold exchanger 40; and further including:

[0045] The installation space 10 is provided with a cold storage component 20; the installation space 10 is also provided with a first opening and a second opening;

[0046] The first opening is connected to the cold exchanger 40 via the first air duct 30. The first opening is also matched with a first partition component 50, which is used to block the flow of cold energy generated by the cold exchanger 40 to the cold storage component 20.

[0047] The second opening is connected to the room via the second air duct 60. The second opening is also matched with a second partition component 70, which is used to block the flow of cold energy from the cold storage component 20 to the room.

[0048] It should be noted that the cold energy compensation device proposed in this embodiment is applied to a refrigerator, and the refrigerator has multiple compartments (such as a freezer compartment, a refrigerator compartment, a variable temperature compartment, etc.). Each compartment has a corresponding door, and the compartment is opened and closed by opening and closing the door. Furthermore, the cold energy compensation device proposed in this embodiment also includes a main control unit, which is electrically connected to the first partition assembly 50 and the second partition assembly 70. The cold exchanger 40 proposed in this embodiment is preferably an evaporator.

[0049] Among them, such as Figure 5 As shown, the refrigeration system also includes a compressor 110, a condenser 120 and a capillary tube 130. The output side of the compressor 110 is connected to the condenser 120, the capillary tube 130 and the heat exchanger 40 in sequence, and then connected to the input side of the compressor 110, thereby forming a refrigerant circulation loop.

[0050] The main control unit can detect the opening and closing status of the cabinet door through a door magnetic sensor or an infrared sensor; and the first air duct 30 is connected to each compartment through the third air duct 100 so that the cold energy generated by the cold exchanger 40 flows into the corresponding compartment. Each third air duct 100 is equipped with a damper that is electrically connected to the main control unit. The main control unit controls whether cold energy flows into the corresponding compartment by controlling the opening and closing of the damper.

[0051] When the temperature of each compartment in the refrigerator meets the requirements, the main control unit controls the first partition component 50 to open, so that the cold energy generated by the cold exchanger 40 flows to the cold storage component 20, so that the cold storage component 20 stores a certain amount of cold energy. After storage, the main control unit controls the first partition component 50 to close, so as to prevent the cold energy generated by the cold exchanger 40 from flowing to the cold storage component 20.

[0052] Then, when the main control unit detects that the cabinet door is open, it will close the damper of the compartment corresponding to the open door to prevent the cold energy generated by the cold exchanger 40 from continuing to flow to the compartment corresponding to the open door, thereby stopping the cooling of the compartment corresponding to the open door. At this time, the compressor 110 remains on, and the first partition component 50 is opened so that the cold energy generated by the cold exchanger 40 flows to the cold storage component 20 again, so that the cold storage component 20 stores more cold energy and improves the energy efficiency of the refrigeration system.

[0053] When the main control unit detects that the cabinet door is closed, it will open the damper of the compartment corresponding to the closed door, so that the cold energy generated by the cold exchanger 40 flows to the compartment corresponding to the closed door, thereby cooling the compartment corresponding to the open door. At this time, the first partition component 50 is closed and the second partition component 70 is opened, so that the cold storage component 20 releases its stored cold energy and flows to the corresponding compartment, thereby achieving rapid cooling of the compartment.

[0054] Specifically, the first partition assembly 50 and the second partition assembly 70 can be combined in the following ways:

[0055] Firstly, such as Figure 1 As shown, both the first partition assembly 50 and the second partition assembly 70 are closed, and at this time the cooling capacity generated by the cold exchanger 40 flows only to the compartment.

[0056] Secondly, such as Figure 2 As shown, the first partition assembly 50 is opened and the second partition assembly 70 is closed. At this time, part of the cold energy generated by the cold exchanger 40 flows to the compartment, and the remaining part flows to the cold storage assembly 20 for storage.

[0057] Thirdly, such as Figure 3 As shown, the first partition component 50 is closed and the second partition component 70 is open. At this time, the cold energy of the cold exchanger 40 and the cold storage component 20 flows to the compartment together to achieve rapid cooling.

[0058] Therefore, when the present invention detects that the door of the corresponding compartment is open, the cold exchanger 40 will stop cooling the compartment and open the first partition component 50 so that the cold energy generated by the cold exchanger 40 flows to the cold storage component 20, thereby effectively preserving the cold energy and reducing energy consumption during the door opening process; when the door of the corresponding compartment is closed, the cold exchanger 40 will resume cooling the compartment, close the first partition component 50, and open the second partition component 70 so that the cold storage component 20 and the cold exchanger 40 release the cold energy simultaneously and flow to the corresponding compartment, thereby increasing the cooling rate after the door is closed, allowing the corresponding compartment to cool down quickly to restore the preset temperature, improving overall energy efficiency and user experience.

[0059] Among them, such as Figure 1 and Figure 4 As shown, this embodiment proposes that the first partition component 50 includes a first motor 501 electrically connected to the main control unit and a first partition door 502 connected to the output end of the first motor 501. In this way, the first motor 501 can drive the first partition door 502 to rotate or move, so that the first partition door 502 opens and closes relative to the first opening, thereby determining whether the cold energy generated by the cold exchanger 40 flows to the cold storage component 20.

[0060] This embodiment proposes that the second partition component 70 includes a second motor 701 electrically connected to the main control unit, and a second partition door 702 connected to the output end of the second motor 701. In this way, the second motor 701 can drive the second partition door 702 to rotate or move, so that the second partition door 702 opens and closes relative to the second opening, thereby determining whether the cold energy of the cold storage component 20 flows to the room.

[0061] In some embodiments, such as Figure 1 As shown, this embodiment provides a structure for a cold storage component 20, including:

[0062] The housing 201 has a sealed chamber inside, which is filled with a phase change material for reversibly absorbing / releasing cold energy.

[0063] In this way, when the first partition component 50 is opened, the phase change material absorbs the cold energy generated by the cold exchanger 40, and when the second partition component 70 is opened and the first partition component 50 is closed, the phase change material releases the absorbed cold energy, thereby achieving rapid cooling of the corresponding room in conjunction with the refrigeration system.

[0064] Of course, in other embodiments, when the cold storage component 20 and the refrigeration system work together to provide cooling to the corresponding room, the temperature around the cold storage component 20 and the cold exchanger 40 will be similar. At this time, even if the first partition component 50 is not closed, the cold storage component 20 will not absorb the cooling generated by the cold exchanger 40, but will only release the cooling it has absorbed.

[0065] The heat transfer channel that runs through the housing 201 is used for heat exchange with an external cold source.

[0066] In this way, this embodiment can further improve the efficiency of the phase change material in absorbing cold energy through the heat transfer channel, so that the cold storage component 20 can store more cold energy in the same amount of time.

[0067] The heat transfer channels are arranged in a serpentine or spiral shape. This design extends the fluid path of the heat transfer channels and enhances the thermal contact time with the phase change material.

[0068] In order to enable the phase change material to better absorb / release cold energy, the phase change material includes any one of paraffin, hydrated salt or microencapsulated material.

[0069] It should be noted that paraffin waxes, such as n-octadecane, have a phase change temperature range of -10℃ to 10℃ and need to be used in combination with metal fillers; hydrated salts, such as calcium chloride hexahydrate, are also relevant. Phase change materials also include cooling gels or other materials that can reversibly absorb / release cold energy, which are not limited here. Cooling gels are materials with special physical properties that are between solid and liquid, possessing a highly reversible structure. Cooling gels are formed by one or more polymeric substances forming a network structure in a solvent, exhibiting a gel state. The formation of gel materials is achieved through a gelation process, which makes the solution viscous and gives it solid-like properties. Therefore, cooling gels have a good ability to store cold energy; and antifreeze agents can be incorporated into cooling gels to improve their low-temperature stability and prevent freezing or crystallization at low temperatures. Common antifreeze agents include alcohols, urea, and phosphate esters. These antifreeze agents can lower the freezing point of water and inhibit the growth of ice crystals, thereby preventing the cooling gel from freezing. Specifically, alcohol-based antifreeze agents such as methanol and ethanol are miscible with water in any proportion. They prevent the cooling gel from freezing by altering the water crystallization process. Urea can also be used as an antifreeze agent, inhibiting ice crystal growth and slowing down the freezing rate of the cooling gel. Phosphate ester antifreeze agents have good antifreeze properties and low-temperature stability, and can be used for the antifreeze protection of various gel materials. Due to the addition of antifreeze agents, the cooling gel can remain soft and maintain sufficient elasticity at low temperatures.

[0070] The surface of the housing 201 is provided with a fin structure for enhancing heat transfer.

[0071] This design can expand the heat exchange area of ​​the cold storage component 20, and the fin structure is in direct contact with the phase change material, which can improve the heat exchange efficiency of the cold storage component 20.

[0072] In some embodiments, such as Figure 1 As shown, a first ventilation component 80 is also provided in the second air duct 60. The first ventilation component 80 is used to make the cold energy of the cold storage component 20 flow quickly to the compartment.

[0073] It should be noted that the first ventilation component 80 is electrically connected to the main control unit; the first ventilation component 80 is preferably a fan or blower.

[0074] Thus, when the cold energy of the cold storage component 20 needs to flow to the room, the main control unit will activate the first ventilation component 80. Compared with natural convection, this embodiment can flow the cold energy of the cold storage component 20 to the room more quickly, so that the room can be cooled down to the preset temperature (equivalent to the temperature required for cooling in the room).

[0075] In some embodiments, such as Figure 1As shown, a second ventilation component 90 is also provided in the first air duct 30. The second ventilation component 90 is used to make the cold energy of the cold exchanger 40 flow quickly to the compartment.

[0076] It should be noted that the second ventilation component 90 is electrically connected to the main control unit; the second ventilation component 90 is preferably a fan or blower.

[0077] Thus, when the cooling capacity of the cold exchanger 40 needs to flow to the room, the main control unit will activate the second ventilation component 90. Compared with natural convection, this embodiment can flow the cooling capacity of the cold exchanger 40 to the room more quickly, so that the room can be cooled down to the preset temperature (equivalent to the temperature required for cooling in the room).

[0078] In this embodiment, the rate of cold energy release can be dynamically adjusted according to the speed of temperature rise in the room. For example, when the room temperature rises rapidly, the main control unit activates the first ventilation component 80 and the second ventilation component 90, or increases the number of cold energy release channels to accelerate the cooling rate; when the room temperature approaches the required cooling temperature, the first ventilation component 80 and / or the second ventilation component 90 are shut off to avoid over-cooling and energy waste. Specifically:

[0079] The fan voltages of the first ventilation component 80 and the second ventilation component 90 are controlled by the difference between the room temperature T and the room set temperature T0 (the temperature required for room cooling). The fan voltage directly affects the speed of the corresponding fan, thereby achieving the purpose of controlling the cold energy release rate of the cold storage component 20 and the cold exchanger 40.

[0080] When 10 < T - T0, the main control unit controls the voltage of the first ventilation component 80 to be 13V and the voltage of the second ventilation component 90 to be 13V. At this time, both the first ventilation component 80 and the second ventilation component 90 operate at high power to quickly cool down the corresponding room.

[0081] When 10 < T - T0 ≤ 15, the main control unit controls the voltage of the first ventilation component 80 to 12V and the voltage of the second ventilation component 90 to 12V. Slightly reducing the voltage of the first ventilation component 80 and the second ventilation component 90 improves the energy conversion efficiency of the first ventilation component 80 and the second ventilation component 90, while the first ventilation component 80 and the second ventilation component 90 have higher power.

[0082] When 5 < T - T0 ≤ 10, the main control unit controls the voltage of the first ventilation component 80 to 8V and the voltage of the second ventilation component 90 to 12V. At this time, the main control unit will continue to reduce the voltage of the first ventilation component 80.

[0083] When 0 < T - T0 ≤ T - 5, the room temperature T is close to the room set temperature T0. At this time, the main control unit shuts down the first ventilation component 80 to reduce energy consumption. At the same time, the main control unit shuts down the first partition component 50 and the second partition component 70, and controls the voltage of the second ventilation component 90 to drop to 10V.

[0084] When -3 < T - T0 ≤ 0, the main control unit still shuts down the first ventilation component 80, but the voltage controlling the second ventilation component 90 continues to decrease to 8V;

[0085] When T-T0≤-3, the room temperature T is lower than the room set temperature T0. At this time, the main control unit shuts down the first ventilation component 80 and the second ventilation component 90.

[0086] In some embodiments, to reduce the space occupied by the cold energy compensation device, the cold storage component 20 is located directly above the cold exchanger 40.

[0087] In some embodiments, the present invention also provides a refrigerator, the refrigerator including the aforementioned cold compensation device.

[0088] Therefore, in this embodiment, when the door of the corresponding compartment is detected to be open, the cold exchanger 40 will stop cooling the compartment and open the first partition component 50 so that the cold energy generated by the cold exchanger 40 flows to the cold storage component 20, thereby effectively preserving the cold energy and reducing energy consumption during the door opening process; when the door of the corresponding compartment is detected to be closed, the cold exchanger 40 will resume cooling the compartment, close the first partition component 50, and open the second partition component 70 so that the cold storage component 20 and the cold exchanger 40 release the cold energy simultaneously and flow to the corresponding compartment, thereby increasing the cooling rate after the door is closed and enabling the corresponding compartment to cool down quickly to restore the preset temperature.

[0089] Specifically, each compartment is equipped with a temperature sensor that is electrically connected to the main control unit. The temperature sensor is used to monitor the temperature T of the corresponding compartment and its temperature drop rate V in real time, so as to determine whether the door is opened or closed to retrieve items, load a large amount of goods, or other scenarios that require a large amount of cooling based on the temperature drop rate V of the compartment.

[0090] When the temperature T of the corresponding compartment reaches the preset temperature, the main control unit only opens the first partition component 50, so that the cold energy generated by the cold exchanger 40 flows to the cold storage component 20, thereby supplementing the cold energy of the cold storage component 20.

[0091] When V > V0 (V0 is the first characteristic rate, and the value can be referenced to the cooling rate in the intermediate room of the no-load cooling test or other similar test. In this embodiment, V0 = 1℃ / min is used as an example), the main control unit determines that the cooling rate of the corresponding room is relatively fast, and determines that it is time to open and close the door to retrieve the item. No large amount of cold energy is required. The refrigeration system is kept to provide cold energy to the corresponding room, and the second partition component 70 and the first ventilation component 80 are kept closed to prevent excessive consumption of the cold energy of the cold storage component 20.

[0092] When V≤V0, the main control unit determines that the cooling rate of the corresponding compartment is slow, indicating that items are being loaded into the compartment and a large amount of cooling capacity is required. At this time, the refrigeration system continues to provide cooling capacity to the corresponding compartment, while the first partition component 50 is closed and the second partition component 70, the first ventilation component 80, and the second ventilation component 90 are opened. This allows the refrigeration system and the cold storage component 20 to simultaneously provide cooling capacity to the corresponding compartment, achieving rapid cooling and preventing the corresponding compartment from being at high temperature for too long, thus avoiding food spoilage. Furthermore, food stored in the rapid freezing compartment can quickly pass through the maximum ice crystal zone, preserving the taste and quality of the food.

[0093] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
