Description

Technical Field

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

[0002] Refrigeration equipment, taking portable mini-fridges as an example, is a device that keeps food at a constant low temperature. Its small size and portability make it easy to transport using family cars, thus it has gradually become the preferred device for refrigerating beverages and other food items during outdoor activities. However, due to space constraints in vehicles, portable mini-fridges are typically small, which limits their battery capacity. When the refrigerator door is opened to remove a beverage, the cold air inside the mini-fridge quickly exchanges heat with the warm air outside. After closing the door, the compressor needs to restart until the temperature in the refrigerated compartment reaches the set value. The compressor's start and stop consume a significant amount of electricity. However, when refrigerating cold drinks, users may frequently open the refrigerator door, causing rapid energy consumption and resulting in a short operating time for the mini-fridge, making it unsuitable for users' needs during extended outdoor activities.

[0003] In view of this, the present invention proposes a refrigeration device to solve or at least alleviate the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this invention is to propose a refrigeration device that aims to solve the technical problem of short working time of miniature refrigerators in usage scenarios where the miniature refrigerator door is frequently opened and closed.

[0005] To achieve the above objectives, this utility model proposes a refrigeration device, comprising:

[0014] The base plate is also provided with mounting holes, the valve cover is disposed in the receiving cavity, and the valve cover is connected to the valve core through the connector;

[0015] The valve core has a first position and a second position that can be switched between each other;

[0016] When the valve core is in the first position, the valve core is in contact with the base plate to seal the air passage.

[0017] When the valve core is in the second position, an air exchange channel is formed between the valve core and the base plate, and the air passage is connected to the valve chamber through the air exchange channel.

[0018] In one embodiment, the valve further includes a sealing ring, and the valve core has an installation groove on the side facing the base plate. The sealing ring is installed in the installation groove. When the valve core is in the first position, the sealing ring is in contact with the base plate to seal the vent hole.

[0019] In one embodiment, the projections of the mounting hole and the valve cover onto the base plate are defined as a first projection and a second projection, respectively.

[0020] Then the outer contour of the first projection is completely within the outer contour of the second projection.

[0021] In one embodiment, the connector includes a threaded member that passes through the valve cover, the valve core, and the elastic member.

[0022] In one embodiment, a sealing plate is provided between adjacent compartments, and the sealing plate is connected to the second side panel;

[0023] The refrigeration equipment also includes a sealing ring, which is sleeved on the storage rack and the side of the sealing ring facing the first side panel fits against the first side panel.

[0024] In one embodiment, the sealing cover includes a cover body, a pivot, and a locking assembly. The cover body is mounted on one end of the second side panel near the main compartment cover via the pivot, and the locking assembly is used to lock the cover body to the sealing plate.

[0025] In one embodiment, the locking assembly includes a limiting block, a push button, a sliding buckle, and a compression spring. The limiting block is disposed on the side of the sealing plate near the main compartment cover. A limiting groove is formed on the side of the limiting block facing the cover. The limiting block and the cover are respectively configured to correspond one-to-one.

[0026] The cover has a through groove corresponding to the position of the limiting groove. The sliding buckle is movably installed in the through groove. The end of the sliding buckle near the limiting groove can extend into or out of the limiting groove. A compression spring is connected to the end of the sliding buckle away from the limiting groove. The end of the compression spring away from the sliding buckle abuts against the side wall of the through groove. One end of the push button is installed on the top surface of the sliding buckle, and the other end of the push button protrudes from the top surface of the cover.

[0027] In one embodiment, the second side panel has two oppositely arranged retrieval slots at one end near the cover. The retrieval slots are connected to the receiving cavity and are used to accommodate human fingers. The cover simultaneously covers the retrieval slots and the receiving cavity.

[0028] According to the technical solution provided by this utility model, the refrigeration equipment includes a main body, a main compartment cover, and a storage rack. The main body has a refrigeration cavity. The main compartment cover is located on the top of the main body to seal the refrigeration cavity. The storage rack is housed in the refrigeration cavity and includes multiple corresponding compartments and multiple sealing covers. Each compartment has a receiving cavity inside, which includes an opening facing the main compartment cover. The sealing cover is located on the opening. Each compartment also includes a valve. A bottom plate is provided at the bottom of the compartment, and the valve is installed on the bottom plate. The bottom plate has an air vent that communicates with the receiving cavity and the refrigeration cavity. When an item is placed in the receiving cavity, the valve opens the air vent. When no item is placed in the receiving cavity, the valve closes the air vent. With this design, when an item is placed in the refrigeration chamber, the valve opens, allowing cold air from the refrigeration chamber to enter through the vent. The sealing cap maintains a consistently low temperature within the refrigeration chamber. When an item is removed from a refrigeration chamber, the sealing cap at the top of that chamber opens, allowing the cold air to escape. At this time, the valve at the bottom of that chamber closes, isolating it from the refrigeration chamber. After the main compartment cover is replaced, cold air from the refrigeration chamber will not enter this refrigeration chamber, thus reducing the space requiring refrigeration within the refrigeration chamber, ultimately reducing energy consumption and extending the operating time of the refrigeration equipment.

[0048] In the field of refrigeration equipment, portable mini-refrigerators, as an innovative product, are increasingly attracting attention and favor. Essentially, they are devices with constant temperature refrigeration functions, their core function being to maintain food at a stable low temperature, thereby ensuring the freshness of food and the refreshing taste of beverages. From a design perspective, portable mini-refrigerators have the advantage of small size; this compact design makes them excellent at utilizing space, making them easy to carry and store. Due to their inherent characteristics, portable mini-refrigerators are gradually becoming the preferred equipment for refrigerating food during outdoor activities.

[0049] According to the applicant's research, in practical applications, due to the limited interior space of family cars, portable mini-fridges are typically designed to be small. When a user opens the mini-fridge door to take out a beverage, the cold air inside the refrigerator quickly exchanges heat with the warm air outside. This is because there is a significant temperature difference between the refrigerator's interior and the external environment; according to thermodynamic principles, heat spontaneously transfers from high-temperature areas to low-temperature areas. In this situation, the cold air inside the refrigerator escapes rapidly, causing the temperature inside the refrigerator compartment to rise rapidly. When the user closes the refrigerator door, the compressor needs to restart to restore the temperature in the refrigerator compartment to the set value. As the core component of the refrigeration system, the compressor consumes a significant amount of electrical energy during its startup and operation. In actual usage scenarios where users take out cold drinks, due to the nature of outdoor activities, users may open the refrigerator door frequently. This frequent operation causes the compressor to continuously cycle between starting and stopping, each time consuming a certain amount of electrical energy. Over time, this rapid consumption of electrical energy leads to a rapid decrease in the mini-fridge's battery power, significantly shortening its operating time. For users, the reduced operating time of mini-fridges means they cannot meet the demand for refrigerated food during extended outdoor activities, which undoubtedly brings many inconveniences to users' outdoor experience.

[0050] In view of this, the present invention proposes a refrigeration device to solve or alleviate the above-mentioned technical problems.

[0051] Please see Figures 1 to 3 In one embodiment of this utility model, the refrigeration device 1000 includes a main body 1, a main compartment cover 2, and a storage rack 3. The main body 1 has a refrigeration cavity 11; the main compartment cover 2 is placed on top of the main body 1 to seal the refrigeration cavity 11; the storage rack 3 is housed within the refrigeration cavity 11 and includes multiple corresponding compartments 31 and multiple sealing caps 32. Each compartment 31 has a receiving cavity 311 inside, with an opening facing the main compartment cover 2. The cover 32 is placed over the opening; the split compartment 31 also includes a valve 312. The bottom of the split compartment 31 is provided with a base plate 313. The valve 312 is installed on the base plate 313 of the split compartment 31. The base plate 313 has an air vent 3131 that communicates with the accommodating cavity 311 and the refrigeration cavity 11. When the accommodating cavity 311 contains an item 2000, the valve 312 opens the air vent 3131. When the accommodating cavity 311 does not contain an item 2000, the valve 312 closes the air vent 3131.

[0052] Specifically, in this embodiment, the storage rack 3 and main body 1 of the refrigeration device 1000 are designed to be detachable. When the refrigeration device 1000 is used in a scenario where the main compartment cover 2 is frequently opened, the storage rack 3 can be inserted entirely into the refrigeration chamber 11 to adapt to this scenario. When the refrigeration device 1000 is used in a scenario where the main compartment cover 2 is opened less frequently or the stored items 2000 are large, the storage rack 3 can be removed from the refrigeration chamber 11, allowing the main body 1 and main compartment cover 2 to be used independently to meet the usage requirements in this scenario. In this embodiment, the main body 1 and main compartment cover 2 together form a miniature refrigerator, which also includes a compressor, power supply, control components, and other devices disposed in the main body 1. It should be noted that the number of separate compartments 31 is at least two. In this embodiment, a total of eight separate compartments 31 are provided in the storage rack 3, wherein the volume of each separate compartment 31 can be determined according to actual needs.

[0053] In this embodiment, when the main compartment cover 2 is frequently opened, the refrigeration device 1000 has two operating states: an open state and a closed state. When the refrigeration device 1000 is in the open state, the sealing covers 32 on the top of one or more of the compartments 31 of the main compartment cover 2 and the storage shelf 3 are open, allowing the item 2000 to be removed. After the item 2000 is removed, the valve 312 closes, preventing the refrigeration chamber 11 and the receiving chamber 311 from communicating. When the refrigeration device 1000 is in the closed state, the main compartment cover 2 and all sealing covers 32 are closed. At this time, the valve 312 of the compartment 31 containing the item 2000 is open, and the refrigeration chamber 11 and the receiving chamber 311 are in a communicating state; the valve 312 of the compartment 31 not containing the item 2000 is closed, and the refrigeration chamber 11 and the receiving chamber 311 are in a non-communicating state.

[0054] With the technical solution of this embodiment, when an item 2000 is placed in the accommodating cavity 311, the valve 312 opens, allowing cold air from the refrigeration cavity 11 to enter the accommodating cavity 311 through the vent 3131. Due to the function of the sealing cover 32, the accommodating cavity 311 can maintain a low temperature continuously. When an item 2000 is removed from a certain accommodating cavity 311, the sealing cover 32 on the top of that accommodating cavity 311 opens, allowing the cold air in that accommodating cavity 311 to dissipate. At this time, the valve 312 closes, isolating that accommodating cavity 311 from the refrigeration cavity 11, preventing the cold air in the refrigeration cavity 11 from dissipating to the outside through the accommodating cavity 311. After the main compartment cover 2 is replaced on the main body 1, the cold air in the refrigeration cavity 11 will not enter the accommodating cavity 311, thereby reducing the space in the refrigeration cavity 11 that needs to be refrigerated, ultimately reducing energy consumption and extending the working time of the refrigeration equipment 1000.

[0055] Further, please refer to Figures 1 to 3In one embodiment of this utility model, the main body 1 includes a first side panel 12 and a bottom shell 13, which together form a refrigeration chamber 11. The split compartment 31 includes a second side panel 314 and a bottom plate 313, which together form a receiving cavity 311. The bottom shell 13 and the bottom plate 313 are spaced apart, and the second side panel 314, the bottom shell 13, and the bottom plate 313 together form a valve chamber 33. A valve 312 is installed in the valve chamber 33, and the second side panel 314 has an air inlet 3141 that communicates with the valve chamber 33. The valve chamber 33 is designed to house the valve 312. The refrigeration chamber 11 is always connected to the valve chamber 33 through the air inlet 3141. When an item 2000 is placed in the receiving cavity 311, the valve chamber 33 communicates with the air inlet 3131, thereby enabling heat exchange between the receiving cavity 311 and the refrigeration chamber 11. This configuration allows the accommodating cavity 311 and the refrigeration cavity 11 to be integrated, with the valve 312 installed in a dedicated valve chamber 33. The valve chamber 33 is formed by the second side enclosure 314, the bottom shell 13, and the bottom plate 313, providing a relatively independent and stable space for the valve 312, which facilitates the installation, disassembly, and maintenance of the valve 312.

[0056] Furthermore, please refer to Figures 3 to 5In one embodiment of this utility model, the valve 312 includes a valve core 3121, an elastic element 3122, a valve cover 3123, and a connector 3124. The valve core 3121 is movably disposed in the valve chamber 33. The bottom surface of the elastic element 3122 is in contact with the bottom shell 13, and the side of the elastic element 3122 away from the bottom shell 13 is connected to the valve core 3121. The bottom plate 313 is also provided with an installation hole. The valve cover 3123 is disposed in the accommodating cavity 311 and is connected to the valve core 3121 through the connector 3124. The valve core 3121 has a first position and a second position that can be switched between each other. When the valve core 3121 is in the first position, the valve core 3121 is in contact with the bottom plate 313 to close the vent hole 3131. When the valve core 3121 is in the second position, a ventilation channel 315 is formed between the valve core 3121 and the bottom plate 313, and the vent hole 3131 communicates with the valve chamber 33 through the ventilation channel 315. Specifically, when no item 2000 is placed in the accommodating cavity 311, the valve core 3121 is pressed into the first position by the elastic element 3122; when an item 2000 is placed in the accommodating cavity 311, due to the gravity of the item 2000, the valve cover 3123 moves towards the bottom shell 13, thereby driving the valve core 3121 to move towards the bottom shell 13, so that the valve core 3121 enters the second position. At this time, a ventilation channel 315 is formed between the valve core 3121 and the bottom plate 313. The gas in the refrigeration cavity 11 enters the accommodating cavity 311 in sequence through the air inlet 3141, the valve chamber 33, the ventilation channel 315 and the air outlet 3131, so that the refrigeration cavity 11 and the accommodating cavity 311 are in a connected state, and heat exchange can be carried out between the two. This design allows the valve core 3121 to open or close the vent 3131 depending on whether an item 2000 is placed in the receiving cavity 311. The position switching of the valve core 3121 relies solely on the gravity of the item 2000 and the elastic force of the elastic element 3122. This design simplifies the structure of the valve 312 and eliminates the need for electricity, thereby saving energy and extending the service life of the refrigeration equipment 1000. It is understood that the elastic element 3122 includes one of a PU elastic block, a spring, and a rubber block, and the connecting element 3124 includes one of a screw, a male-female screw, and a rivet. The specific implementation of the elastic element 3122 and the connecting element 3124 can be adopted according to actual needs.

[0057] In one embodiment of this utility model, please refer to Figure 4 and Figure 5The valve 312 also includes a sealing ring 3125. A mounting groove is provided on the side of the valve core 3121 facing the base plate 313. The sealing ring 3125 is installed in the mounting groove. When the valve core 3121 is in the first position, the sealing ring 3125 is in contact with the base plate 313 to seal the vent 3131. The sealing ring 3125 is made of a flexible material such as rubber, modified rubber, or polyurethane. This design further enhances the sealing effect of the valve core 3121 on the vent 3131, thus preventing cold air from the refrigeration chamber 11 from entering the refrigeration chamber 311 when no item 2000 is placed in it.

[0058] In one embodiment of this utility model, please refer to Figure 4 and Figure 5 Definition: The projections of the mounting hole and the valve cover 3123 onto the base plate 313 are the first projection and the second projection, respectively; the outer contour of the first projection is completely within the outer contour of the second projection. For example, if both the mounting hole and the valve cover 3123 are cylindrical, the diameter of the mounting hole should be smaller than the diameter of the valve cover 3123. This arrangement makes the size of the valve cover 3123 larger than the size of the mounting hole. Thus, when the storage rack 3 is removed from the refrigeration chamber 11 as a whole, the valve cover 3123 can be locked inside the receiving chamber 311, preventing it from falling off through the mounting hole. This allows the valve cover 3123 to drive the valve core 3121 and the elastic element 3122 to move synchronously with the rest of the compartment 31, avoiding the need to reinstall the valve 312 every time the storage rack 3 is installed.

[0059] In one embodiment of this utility model, the connector 3124 includes a threaded component that passes through the valve cover 3123, the valve core 3121, and the elastic component 3122. Please refer to [link / reference]. Figure 4 Specifically, the threaded component uses a male and female screw, which connects the valve cover 3123, valve core 3121, and elastic element 3122 simultaneously. This allows all three components to be connected using a single threaded component, avoiding the relatively cumbersome assembly steps of first connecting the elastic element 3122 to the valve core 3121 and then connecting the valve core 3121 to the valve cover 3123. This improves the overall assembly efficiency of the storage rack 3 and enhances the connection strength between the valve cover 3123, valve core 3121, and elastic element 3122.

[0060] Please see Figure 2 and Figure 6In one embodiment of this utility model, a sealing plate 34 is provided between adjacent compartments 31, and the sealing plate 34 is connected to the second side panel 314; the refrigeration device 1000 also includes a sealing ring 35, which is sleeved on the storage rack 3, and the side of the sealing ring 35 facing the first side panel 12 is in contact with the first side panel 12. Specifically, a sealing plate 34 is provided at the intervals of the compartments 31, and the sealing plate 34 is integrally formed with the second side panel 314. In this embodiment, the second side panel 314, the bottom plate 313, and the sealing plate 34 are integrally injection molded to improve the overall strength of the storage rack 3. By providing a sealing ring 35 around the storage rack 3, the cavity between the sealing plate 34 and the bottom shell 13 has a certain airtightness. When the main compartment cover 2 is opened, the cold air in this part of the cavity will not escape, thereby keeping the temperature in the cavity constant at a low temperature, which can further reduce the energy consumption of the refrigeration device 1000 and help to further extend the service life of the refrigeration device 1000.

[0061] Please see Figure 2 , Figure 7 and Figure 8 In one embodiment of this utility model, the sealing cover 32 includes a cover body 321, a rotating shaft 322, and a locking assembly 323. The cover body 321 is installed on the end of the second side panel 314 near the main compartment cover 2 via the rotating shaft 322. The locking assembly 323 is used to lock the cover body 321 to the sealing plate 34. The sealing cover 32 allows cold air to accumulate in the accommodating cavity 311, reducing the leakage of cold air. By providing the locking assembly 323, the user can loosen or fix the cover body 321 by opening or closing the locking assembly 323, preventing the cover body 321 from not closing tightly and causing cold air leakage. The installation method of the rotating shaft 322 allows the cover body 321 to rotate around the rotating shaft 322 to open or close like a door, which is simple and effortless to operate. It eliminates the need to completely disassemble and reinstall the cover body 321, making it convenient for the user to place or retrieve items 2000 into or from the accommodating cavity 311, saving operation time.

[0062] Please see Figure 2 , Figure 7 and Figure 8In one embodiment of this utility model, the locking assembly 323 includes a limiting block 3231, a push button 3232, a sliding buckle 3233, and a compression spring 3234. The limiting block 3231 is disposed on the side of the sealing plate 34 near the main compartment cover 2. A limiting groove is formed on the side of the limiting block 3231 facing the cover body 321. The limiting blocks 3231 and the cover body 321 are respectively provided. A through groove 3235 is formed on the cover body 321 at the position corresponding to the limiting groove. The sliding latch 3233 is movably installed in the through groove 3235. The end of the sliding latch 3233 near the limiting groove can extend into or retract from the limiting groove. The end of the sliding latch 3233 away from the limiting groove is connected to a compression spring 3234. The end of the compression spring 3234 away from the sliding latch 3233 abuts against the side wall of the through groove 3235. One end of the push button 3232 is installed on the top surface of the sliding latch 3233, and the other end of the push button 3232 protrudes from the top surface of the cover 321. When it is necessary to open the cover 321, the user only needs to press the push button 3232 and push it away from the limiting block 3231 to disengage the sliding latch 3233 from the limiting groove. This releases the limiting block 3231 from restricting the cover 321, allowing the cover 321 to open around the pivot 322. Similarly, when the cover 321 needs to be closed, the user first pushes the push button 3232 to the side away from the limiting block 3231, causing the compression spring 3234 to shorten. After the sliding buckle 3233 aligns with the limiting groove, the push button 3232 is released, and the sliding buckle 3233 will automatically insert into the limiting groove under the action of the compression spring 3234. The operation is convenient and quick, the structure is simple, and the reliability is high. On this basis, a sliding plate 3236 can be set below the sliding buckle 3233 to slide and cooperate with the sliding buckle 3233, serving as a guide for the sliding of the sliding buckle 3233 to improve the stability of the sliding of the sliding buckle 3233. In addition, a sealing gasket can be set between the cover 321 and the second side wall 314. The sealing gasket is made of one of the flexible materials such as rubber, modified rubber, and polyurethane to improve the airtightness between the cover 321 and the second side wall 314.
