Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration technology, and in particular to refrigeration equipment. Background Technology
[0002] In related technologies, refrigerator crisper drawers improve the temperature difference between the front and back by using top-mounted airflow. However, because the air vents are located directly above the drawer, cold air tends to blow directly onto the food, causing significant temperature fluctuations on the food's surface. To reduce these fluctuations, the air vents are changed from concentrated airflow to dispersed airflow, expanding the cold air coverage area and preventing direct airflow onto the food. However, when the top of the crisper drawer also houses display panels, lights, or other functional components, the placement of the air vents is affected by these components, causing them to be offset towards one area. This results in the area below the functional components being farther from the air vents, creating a significant temperature difference between the area below and the area closer to the air vents.

[0033] Temperature is an essential condition for food preservation. Food preservation requires a constant temperature and a suitable low temperature, ensuring minimal temperature fluctuations for optimal results. Rear-venting systems are prone to uneven temperature distribution. When storing a large quantity of food, items near the vent may overfreeze, while items further away from the vent and closer to the front of the drawer may remain warm, posing a risk of poor preservation. This is because the vent is located at the back of the drawer. When cold air blows out, it first exchanges heat with the food at the back of the drawer before reaching the front. Cold air loses some heat during this flow, causing different temperature levels for the food at the front and back. When storing a large quantity of food, items near the vent may overfreeze, while items further away and closer to the front of the drawer may remain warm, posing a risk of poor preservation. Furthermore, with only one vent, dead zones can form within the drawer, where food cools more slowly, resulting in uneven temperature distribution.
[0034] In related technologies, uneven temperature distribution can be improved by directing airflow above the drawers. This top-mounted airflow is less affected by large containers or food piles inside the refrigerator, thus preventing localized overheating or cooling caused by obstruction. This helps maintain a more even temperature throughout the refrigerator, further enhancing its preservation effect.
[0035] However, with top-ventilation systems, the air vents are positioned directly above the drawer, causing cold air to blow directly onto the food. This results in significant temperature fluctuations on the food's surface, which can lead to recrystallization of ice crystals formed on the food's surface cells. This exacerbates cell dehydration, directly affecting the food's taste and nutritional value, and is detrimental to food preservation.
[0036] The following reference Figures 1 to 6 This section explains how the refrigeration equipment of this utility model solves the above-mentioned problems. The refrigeration equipment can be a refrigerator, a display case, a freezer, or other similar products.
[0037] It is understood that the refrigeration equipment of this utility model embodiment includes a housing 101, which is the overall support structure of the refrigeration equipment. Components of the refrigeration system, such as the compressor, air cooler, and condenser, can all be installed in the housing 101. The housing 101 has a storage compartment, which can be any one of a refrigerator compartment, a variable temperature compartment, or a freezer compartment. The housing 101 is provided with an air outlet 201, the position of which corresponds to the storage space. The cold air generated by the heat exchange of the refrigeration system flows along the air duct and is blown out from the air outlet 201, then enters the storage compartment. Because the air temperature is low and the food temperature is high, heat exchange occurs directly between the two, causing the air temperature to rise and the food temperature to drop. The air after heat exchange returns to the air duct through the return air vent, where it exchanges heat again with the evaporator of the refrigeration system. Through this continuous circulation, the temperature of the food is reduced.
[0038] Reference Figure 1 and Figure 2 As shown, it can be understood that the storage container 102 is located in the storage room. For example, the storage container 102 can be a food storage drawer or a food storage tray. The storage container 102 can be movable. Specifically, guide rails 103 can be provided on both sides of the storage room. The guide rails 103 can extend along the front and rear direction of the box body 101. Sliding parts 104 can be provided on both sides of the storage container 102. The two sliding parts 104 are slidably connected to the two guide rails 103 respectively. The movement of the storage container 102 can be realized by sliding the sliding parts 104 relative to the guide rails 103.
[0039] Reference Figure 1 and Figure 2As shown, it can be understood that the refrigeration equipment in this embodiment of the present invention is further provided with an air guide 105. The air guide 105 has an air duct 202 communicating with the air outlet 201. The air guide 105 has a first air outlet 106 and a second air outlet 107, which are disposed on the bottom wall of the air guide 105 and located above the storage container 102 for supplying air to the storage container 102. The top of the storage container 102 has an opening 108, and both the first air outlet 106 and the second air outlet 107 face the opening 108. With the addition of the air guide 105, the cold air blown out from the air outlet 201 first enters the air duct 202 of the air guide 105, and then is blown out from the first air outlet 106 and the second air outlet 107 respectively, which can cool the food from multiple positions. Furthermore, the air is blown from top to bottom into the storage container 102, which helps to reduce the difference in the distance the cold air travels in different locations, thereby making the temperature drop in different locations more consistent.
[0040] Reference Figure 1 and Figure 2 As shown, it can be understood that the air guide 105 includes a shelf 109, an air duct fixing plate 110, and a first insulation layer 111. The shelf 109 is used to separate different storage spaces. The shelf 109 is located above the air duct fixing plate 110. The first insulation layer 111 is located between the shelf 109 and the air duct fixing plate 110. The air duct fixing plate 110 and the first insulation layer 111 define an air guide duct 202. The first air outlet 106 and the second air outlet 107 are provided on the air duct fixing plate 110.
[0041] It should be noted that in some other embodiments, the air guide 105 may also be an independent component, which has no connection or combination relationship with the shelf 109.
[0042] Reference Figure 5 and Figure 6As shown, it can be understood that the first air outlet 106 is provided with a diversion structure 501, which is used to simultaneously guide the airflow of the air guide duct 202 to multiple air outlet directions. Specifically, the air guide 105 is provided with ventilation holes 502, and the diversion structure 501 includes multiple first guide vanes 603. The multiple first guide vanes 603 are disposed in the ventilation holes 502 and arranged circumferentially along the ventilation holes 502. A first air outlet 601 is formed between two adjacent first guide vanes 603. The first guide vanes 603 are inclined along the axial direction of the ventilation holes 502. The diversion structure 501 forms an air inlet and multiple first air outlets 601. The air inlet is used to communicate with the air guide duct 202, and the first air outlets 601 are used to communicate with the storage compartment. At least two first air outlets 601 have different orientations. The diversion structure 501 is used to simultaneously guide the airflow from the air inlet to multiple first air outlets 601 and blow it into the storage room. Since the multiple first air outlets 601 are oriented differently, the cold air can be blown into the storage room from multiple different directions, making the airflow distribution in the storage room more uniform and the temperature in the storage room more uniform.
[0043] In this embodiment, the low-temperature airflow generated by the refrigeration system of the refrigeration equipment enters the air inlet of the distributor and, under the guidance of the distributor structure 501, flows simultaneously to multiple first air outlets 601. Since the multiple first air outlets 601 have different orientations, the airflow can enter the storage container 102 from multiple different directions at the same time, making the airflow distribution in the storage container 102 more uniform and the temperature in the storage container 102 more uniform. This reduces the occurrence of food becoming too cold or too hot, thus extending the food's shelf life. In addition, it can also reduce the formation of condensation or frost on the surface of the storage container 102, resulting in better overall reliability and a better user experience.
[0044] It should be noted that, Figure 6 In the first embodiment, all the first air outlets 601 have different directions. In other embodiments, the multiple first air outlets 601 can have at least two air outlet directions. In other words, there can also be two first air outlets 601 with the same air outlet direction, but different from the air outlet direction of the third first air outlet 601.
[0045] It is understood that the surface of the first guide vane 603 along its thickness direction has an angle greater than zero with the axial direction of the ventilation hole 502. That is, the first guide vane 603 includes a first connecting section 607 connected to the inner wall of the ventilation hole 502. The arrangement direction of the first connecting section 607 forms an acute angle with the axial direction of the ventilation hole 502, so that the air outlet direction of the first air outlet 601 is not parallel to the axial direction of the ventilation hole 502, but forms a certain angle with respect to the axial direction of the ventilation hole 502. Furthermore, the first connecting sections 607 of the multiple first guide vanes 603 are arranged in a circumferential array along the ventilation hole 502, so that the airflow after being discharged from the multiple first air outlets 601 can form a swirling flow, that is, it can be blown into the storage space in a spiral shape, thereby making the cold air distribution in the storage space more uniform.
[0046] It is understandable that there can be one or more air inlets. When there is one air inlet, the diversion structure 501 simultaneously guides the airflow in the air inlet to multiple first air outlets 601. When there are multiple air inlets, the diversion structure 501 simultaneously guides the airflow in multiple air inlets to multiple first air outlets 601. When the first guide vane 603 extends to the end of the ventilation hole 502 away from the storage space, the first guide vane 603 divides the end of the ventilation hole 502 away from the storage space into multiple ports, each port forming an air inlet, thus realizing that the diversion device has multiple air inlets. When the diversion structure 501 is equipped with a guide ring, and the guide ring is set at the end of the first guide vane 603 away from the storage space, the guide ring as a whole forms an air inlet, thus realizing that the diversion structure 501 has one air inlet.
[0047] It should be noted that in some other embodiments, the first air outlet 601 of the air guide 105 can be formed directly on the air guide 105 by drilling, injection molding, or other methods. For example, the air guide 105 has a spherical surface, on which multiple first air outlets 601 are provided, each first air outlet 601 being perpendicular to the corresponding cross-section on the spherical surface. Another example is that multiple first guide vanes 603 are staggered within the ventilation hole 502. Some of the first guide vanes 603 are inclined to the left at different angles; some are inclined to the right at different angles; some are inclined forward at different angles; and some are inclined backward at different angles, thus forming multiple first air outlets 601 in different directions.
[0048] use Figure 6The advantage of the illustrated scheme is that the first guide vane 603 has a relatively long guiding path, and a first air outlet 601 can be formed between two adjacent first guide vanes 603, which can play a better guiding role and effectively change the original direction of the airflow, allowing it to continue flowing in different directions after passing through the diversion structure 501 to reach different areas of the storage space. Furthermore, the ventilation area of the first air outlet 601 formed between two adjacent first guide vanes 603 is large, and the first guide vanes 603 obstruct the airflow less, resulting in less energy loss.
[0049] Reference Figure 6 As shown, it can be understood that the diversion structure 501 also includes a first connecting portion 604, which is disposed within the ventilation hole 502. The two sides of the first guide vane 603 are respectively connected to the hole wall of the ventilation hole 502 and the outer peripheral wall of the first connecting portion 604. For example, the outer peripheral wall of the first connecting portion 604 can be cylindrical, and the axis of the first connecting portion 604 can coincide with the axis of the ventilation hole 502.
[0050] In this embodiment, by providing a first connecting portion 604, all the first guide vanes 603 on the side away from the ventilation hole 502 can be connected together to form a whole, thereby increasing structural strength, enhancing airflow guidance capacity, reducing damage, and extending service life. Furthermore, if the first guide vanes 603 are connected at the axis of the ventilation hole 502, multiple airflows at that axis will mutually restrain each other, making it difficult for them to continue flowing along the guiding direction of the first guide vanes 603. The first connecting portion 604 can block the side of two adjacent first guide vanes 603 away from the ventilation hole 502, reducing the probability of turbulence at the small angle between adjacent first guide vanes 603, thus improving the airflow guidance effect and reducing the risk of cross-flow.
[0051] Reference Figure 6 As shown, it can be understood that the first connecting part 604 is annular, and the diversion structure 501 also includes a second connecting part 605 and a plurality of second guide vanes 606. The second connecting part 605 is disposed inside the first connecting part 604, and the plurality of second guide vanes 606 are arranged circumferentially along the ventilation hole 502. The two sides of the second guide vanes 606 are respectively connected to the inner peripheral wall of the first connecting part 604 and the outer peripheral wall of the second connecting part 605. The surface of the second guide vane 606 along the thickness direction forms an angle with the axial direction of the ventilation hole 502. A guide channel is formed between two adjacent second guide vanes 606, and a second air outlet 602 is formed at the end of the guide channel away from the air inlet.
[0052] For example, the second connecting part 605 can be cylindrical, and its axis can coincide with the axis of the ventilation hole 502. The second guide vanes 606 can be provided in four, six, eight, or other suitable numbers. The second guide vanes 606 can be inclined; specifically, the surface of the second guide vane 606 in the thickness direction is not parallel to the axial direction of the ventilation hole 502, but forms an angle with it. Consequently, the guiding direction of each guide channel is not parallel to the axial direction of the ventilation hole 502, and the air outlet direction of the second air outlet 602 is not parallel to the axial direction of the ventilation hole 502, but forms a certain angle with it. Therefore, after the airflow is discharged from multiple second air outlets 602, it can form a swirling flow, that is, it can be blown into the storage space in a spiral shape, which can just fill the middle area of the spiral airflow sent out by the first air outlet 601, making the distribution of cold air entering the storage space more uniform, thereby making the humidity distribution in the storage space more uniform.
[0053] It should be noted that in some other embodiments, the second air outlet 602 may also be parallel to the axial direction of the ventilation hole 502. In this way, the first air outlet 601 diffuses along the outer periphery of the ventilation hole 502, and the second air outlet 602 flows along the middle of the ventilation hole 502. Overall, this can make the distribution of cold air entering the storage space more uniform, thereby making the humidity distribution in the storage space more uniform. Alternatively, the tilt angles of the first guide vane 603 and the second guide vane 606 are different. For example, the first guide vane 603 includes a first connecting section 607 connected to the inner wall of the ventilation hole 502, and the second guide vane 606 includes a second connecting section 608 connected to the inner wall of the first connecting part 604. The angle between the first connecting section 607 and the axis of the ventilation hole 502 is greater than the angle between the second connecting section 608 and the axis of the ventilation hole 502. The airflow guided by the first guide vane 603 flows along the ventilation hole 502. The radial diffusion range of the airflow guided by the second guide vane 606 is wider, while the radial diffusion range of the airflow guided by the second guide vane 606 along the ventilation hole 502 is narrower. That is, the radial diffusion range of the airflow guided by the second guide vane 606 along the ventilation hole 502 is smaller than that of the airflow guided by the first guide vane 603 along the ventilation hole 502. This reduces the interference between the two airflows and the impact on the flow of airflow, making the airflow passing through the ventilation hole 502 diffuse more widely in the storage space.
[0054] Reference Figure 1 and Figure 2As shown, it can be understood that the refrigeration equipment in this embodiment of the present invention also includes a functional component 112. The functional component 112 may be a display panel, a lamp, or other components. The functional component 112 is disposed on one side of the air guide 105, and the first air outlet 106 and the second air outlet 107 are located on the same side of the functional component 112. Because the functional component 112 occupies part of the space of the air guide 105, the first air outlet 106 and the second air outlet 107 cannot be evenly distributed on the air guide 105, resulting in a lower airflow in the area below the functional component 112. That is, the airflow in the area of the storage container 102 corresponding to the functional component 112 is less than the airflow in the area of the storage container 102 corresponding to the first air outlet 106 and the second air outlet 107. In this embodiment, the airflow direction of the second air outlet 107 is towards the area below the functional component 112. That is, the second air outlet 107 is provided with a second air outlet 602, and the airflow direction of all the second air outlets 602 is towards the area below the functional component 112. The second air outlet 107 adopts a directional air outlet design to compensate for the air volume in the area below the functional component 112, effectively improve the temperature uniformity, and ensure the overall preservation effect of the storage container 102.
[0055] Understandably, the function of the first air outlet 106 is to ensure that the airflow passing through it is evenly diffused in all directions, avoiding direct blowing onto the food, and simultaneously improving the temperature uniformity within the storage container 102. Due to the presence of the functional component 112, the first air outlet 106 cannot be evenly distributed above the storage container 102, affecting the cooling of the area below the functional component 112 and causing uneven temperature distribution within the storage container 102. By providing the second air outlet 107, the airflow from the second air outlet 107 supplements the amount of cold air in the area below the functional component 112, thereby reducing the temperature difference within the storage container 102 and improving temperature uniformity. Furthermore, the airflow from the second air outlet 107 is angled, not directly towards the food, and its function is to supplement the amount of cold air in the area below the functional component 112. This means that the airflow from the second air outlet 107 is not large, and the airflow directly blowing onto the food is also small. Therefore, the airflow from the second air outlet 107 will not significantly increase the surface temperature fluctuations of the food. By combining the first air outlet 106 and the second air outlet 107, the cold air coverage area is expanded, avoiding the cold air blowing directly on the food and causing large fluctuations in the surface temperature of the food. The second air outlet 107 adopts a directional air outlet design to compensate for the air volume in the area below the functional component 112, effectively improving the temperature uniformity and ensuring the overall freshness preservation effect of the storage container 102.
[0056] Understandably, the housing 101 has an opening that connects to the storage compartment. The storage container 102 enters or exits the storage compartment through the opening. The functional component 112 is located on the side of the air guide 105 near the opening, making it convenient for users to adjust the temperature, turn the lights on and off, etc. at the opening.
[0057] It should be noted that in some other embodiments, the functional component 112 may also be located at other positions on the air guide 105. For example, two storage containers 102 are provided along the width direction of the refrigeration equipment, and the functional component 112 is located between the two storage containers 102.
[0058] Reference Figure 1 and Figure 2 As shown, there are two first air outlets 106 and two second air outlets 107. The two first air outlets 106 are arranged side-by-side with a gap along the width of the refrigeration equipment, and the two second air outlets 107 are also arranged side-by-side with a gap along the width of the refrigeration equipment. This makes the distribution of the first air outlets 106 and the second air outlets 107 more uniform, which is beneficial to improving the temperature uniformity of the storage container 102. The first air outlets 106 are located on the side of the second air outlets 107 away from the functional component 112, which shortens the airflow path from the second air outlets 107 to the functional component 112 and reduces the interference of the airflow from the first air outlets 106 on the airflow from the second air outlets 107.
[0059] It should be noted that in some other embodiments, the number of first air outlets 106 and the number of second air outlets 107 may be more than three, and the number of first air outlets 106 and the number of second air outlets 107 may not be equal. This utility model embodiment does not make specific limitations.
[0060] In related technologies, refrigerators are mainly divided into single-system and dual-system refrigerators. Compared with single-system refrigerators, dual-system refrigerators are more popular and recognized by consumers because they prevent odor mixing and have better refrigeration and humidity control. Therefore, some ice-temperature preservation drawers are gradually adopting refrigeration with air circulation for temperature control. However, this method also has shortcomings. To balance energy consumption, refrigeration temperature, and the reliability of refrigeration by the evaporator, the evaporator undergoes defrosting after each cooling cycle. During defrosting, a refrigeration fan rotates to circulate hot air from the refrigeration unit into the evaporator, using heat conduction and heat exchange to melt the frost. The advantage of this defrosting method is that the refrigeration temperature fluctuates less, but the disadvantage is that the defrosting time is too long, and the ice-temperature preservation drawer cannot request cooling in time during the defrosting process, ultimately resulting in large temperature fluctuations in the ice-temperature preservation drawer and affecting the preservation effect. For this reason, ice-temperature preservation drawers often adopt an integrated design to reduce the temperature rise caused by defrosting. However, the integrated design has the problems of high overall cost and reduced internal volume.
[0061] Reference Figure 3 and Figure 4As shown, the storage container 102 includes an inner cavity 301, a second insulation layer 302, and a fixing base 303. The inner cavity 301, the second insulation layer 302, and the fixing base 303 are arranged sequentially from top to bottom. An opening 108 is located in the inner cavity 301. At least a portion of the second insulation layer 302 is located on the side of the inner cavity 301 away from the opening 108. The inner cavity 301 and the fixing base 303 are fixed together by a connector, thereby also fixing the second insulation layer 302 between the inner cavity 301 and the fixing base 303. Specifically, the connector includes a snap-fit protrusion 304 and a snap-fit recess 305. The fixing base 303 is provided with the snap-fit protrusion 304, and the inner cavity 301 is provided with the snap-fit recess 305. The snap-fit protrusion 304 and the snap-fit recess 305 cooperate with each other to achieve a fixed connection between the inner cavity 301 and the fixing base 303. By adding a second insulation layer 302 to the storage container 102, the insulation performance of the storage container 102 is improved, and the temperature rise caused by defrosting is reduced. Compared with the integrated bucket solution, the storage container 102 has advantages in overall cost and effective volume.
[0062] Understandably, the second insulation layer 302 can be foam, and the connectors can be screws or other components.
[0063] Reference Figure 5 As shown, it can be understood that the air guide 105 is provided with a sealing part 503. The sealing part 503 extends downward from the air guide 105 and overlaps the upper edge of the opening 108, so that the interior of the storage container 102 forms a relatively sealed state, reducing air leakage on both sides of the storage container 102 and preventing condensation and frost from forming on the guide rail 103 due to excessively low temperature when the humidity is high.
[0064] Furthermore, the upper edge of the opening 108 is inclined along the depth direction of the refrigeration equipment, and similarly, the lower edge of the sealing part 503 is also inclined along the depth direction of the refrigeration equipment. The upper edge of the opening 108 and the lower edge of the sealing part 503 are parallel. Specifically, the end of the upper edge of the opening 108 closer to the opening is defined as end A, and the end of the upper edge of the opening 108 farther from the opening is defined as end B, with end A being higher than end B. The area of the sealing part 503 corresponding to end A extends downward from the air guide 105 by a smaller distance, while the area of the sealing part 503 corresponding to end B extends downward from the air guide 105 by a larger distance. This facilitates the insertion and removal of the storage container 102 from the storage space, avoiding significant friction or jamming during the pulling process of the storage container 102, which would affect the user experience.
