DETAILED DESCRIPTION

[0023] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0024] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0025] In order to reduce the probability of cold leakage, some related technologies reduce the intrinsic thermal conductivity of the sealing strip material itself through material preparation processes such as foaming, compounding or material optimization to reduce the thermal conductivity of the overall molded part, but the cost is relatively high; other related technologies adjust the airbag structure in the sealing strip, for example, by increasing the number of airbags to reduce the degree of internal gas convection to achieve an increase in thermal resistance, thereby reducing the probability of cold leakage, but this method is relatively complex and costly.

[0026] The present application embodiment provides a refrigeration device. Figure 1 The refrigeration equipment includes a housing, a door, a sealing strip 1, and a thermal insulation member 2. The housing defines a storage cavity and an access opening communicating with the storage cavity. The door can selectively open or close the access opening. The sealing strip 1 is connected to the door on one side along its thickness, and abuts the housing on its other side along its thickness. A first air pocket 12a1 is formed within the sealing strip 1. The thermal insulation member 2 is disposed within the first air pocket 12a1.

[0027] The embodiment of the present application provides a refrigeration device. By providing a sealing strip 1 between the cabinet and the door, not only can the gap between the cabinet and the door be sealed to reduce cold leakage from the cabinet, but also a buffering effect can be provided between the door and the cabinet, reducing damage caused by impact between the two, improving the service life of the cabinet and the door, and reducing noise when closing the door. By forming a first airbag 12a1 in the sealing strip 1, on the one hand, when the sealing strip 1 abuts against the cabinet, the sealing airbag in the sealing strip 1 can play a damping and buffering role between the cabinet and the door, reducing damage caused by impact between the two, thereby improving the service life of the door and the cabinet and reducing noise when closing the door; on the other hand, when the door is deformed, the volume change of the first airbag 12a1 can be used to compensate for the size of the door, thereby further reducing the situation where a large gap occurs between the door and the cabinet. By filling the first airbag 12a1 with a heat insulating member 2, the overall thermal conductivity of the sealing strip 1 can be reduced, so that the heat exchange between the storage cavity and the outside world can be further reduced. In this way, not only can the cold leakage be further reduced to save the energy consumption of the refrigeration equipment, but also compared with the prior art of changing the material of the sealing strip 1 or increasing the number of airbags, the present application sets a heat insulating member 2 in the first airbag 12a1, which is simple in process and low in cost.

[0028] It should be noted that the above-mentioned thermal insulation component 2 is a component with a fixed shape, and its physical form is solid.

[0029] For example, in one embodiment, the shape of the box is not limited, for example, it can be a cuboid or a cube, etc. The shape of the door is also not limited, for example, it can be a rectangle or a square, etc.

[0030] Illustratively, in one embodiment, the refrigeration device may be a refrigerator or a freezer.

[0031] In one embodiment, the thermal insulation member 2 is made of aerogel. Using aerogel as the material for the thermal insulation member 2, due to its nano-scale porous structure, results in a low thermal conductivity. This can further minimize heat exchange between the storage cavity and the outside world, reducing the likelihood of cold leakage and the energy consumption of the refrigeration equipment.

[0032] For example, in one embodiment, the thermal insulation element 2 can be made of aerogel with a toughening agent added. On the one hand, using aerogel as the material for the thermal insulation element 2, due to its nano-scale porous structure, results in a low thermal conductivity. This can further minimize heat exchange between the storage cavity and the outside world, reducing the chance of cold leakage and the energy consumption of the refrigeration equipment. On the other hand, the addition of a toughening agent can address the brittleness and low density of aerogel, improve the overall toughness of the thermal insulation element 2, and reduce the risk of aerogel breakage and seal failure during the closing process of the sealing strip 1. The aerogel also provides excellent operational stability.

[0033] It should be noted that the aerogel itself is brittle in structure. After being filled into the first airbag 12a1, the sealing strip 1 will be squeezed during the door closing process, causing the aerogel in the first airbag 12a1 to break. After the breakage, the aerogel particles will rub against the inside of the sealing airbag to destroy the first airbag 12a1, causing the sealing performance of the sealing strip 1 to fail.

[0034] It should be noted that the toughening agent is a substance that reduces brittleness and increases toughness without affecting the main functions of aerogel such as thermal insulation.

[0035] For example, in one embodiment, the toughening agent can be a rubber-based material. Selecting a rubber-based material as the toughening agent can, on the one hand, address the brittleness and low density of aerogel, improve the overall toughness of the thermal insulation member 2, and reduce the risk of aerogel breakage and seal failure during the closing process of the sealing strip 1. This improves the operational stability of the aerogel. Furthermore, the rubber-based material exhibits excellent elasticity and sealing properties, allowing it to closely adhere to the inner wall of the first airbag 12a1 to provide dimensional compensation. Furthermore, the rubber-based material exhibits excellent durability, resisting erosion from various environmental factors, such as ultraviolet rays, oxidation, and chemical corrosion, thereby extending the service life of the thermal insulation member 2. Furthermore, the rubber-based material exhibits excellent plasticity and processability, making it easier to fill the first airbag 12a1 after combining with the aerogel.

[0036] In one exemplary embodiment, the toughening agent is a thermoplastic elastomer. By selecting a thermoplastic elastomer as the toughening agent, on the one hand, the thermoplastic elastomer can address the brittleness and low density of aerogel, thereby improving the overall toughness of the thermal insulation element 2 and reducing the risk of aerogel breakage and seal failure caused by the sealing strip 1 during door closing. Furthermore, the aerogel exhibits excellent elasticity and sealing properties. When combined with the aerogel, the thermoplastic elastomer can tightly adhere to the wall surface within the first airbag 12a1, providing dimensional compensation. Furthermore, the thermoplastic elastomer exhibits excellent durability, resisting various environmental factors such as ultraviolet rays, oxidation, and chemical corrosion, thereby extending the service life of the thermal insulation element 2.

[0037] For example, in one embodiment, the toughening agent is a rubber material and a thermoplastic elastomer material. Thus, the combination of the thermoplastic elastomer material, the rubber material, and the aerogel can significantly improve the thermal insulation performance of the sealing strip 1, further reducing heat exchange between the storage cavity and the outside world, lowering the chance of cold leakage and reducing the energy consumption of the refrigeration equipment.

[0038] In one embodiment, the particle size of the aerogel is between 50 μm and 100 μm. For example, the particle size of the aerogel can be 50 μm, 55 μm, 60 μm, 65 μm, 70 μm, 75 μm, 80 μm, 85 μm, 90 μm, 95 μm, or 100 μm. Thus, by setting aerogel of an appropriate particle size, on the one hand, the pore structure of the aerogel can be optimized, its thermal insulation performance can be improved, and heat exchange between the storage cavity and the outside world can be effectively reduced, reducing the probability of cold leakage and the energy consumption of the refrigeration equipment; on the other hand, aerogel of an appropriate particle size can maintain appropriate softness and elasticity, which allows the first airbag 12a1 to recover quickly when squeezed by the box body and the door body, thereby acting as a damping buffer, reducing damage caused by the impact between the two, increasing the service life of the door body and the box body, and reducing the noise when the door is closed; on the other hand, aerogel of an appropriate particle size can be easily combined with other materials such as resin, rubber, or thermoplastic plastic to form the thermal insulation member 2.

[0039] In one embodiment, the heat insulating member 2 is in the shape of an elongated strip. Thus, by placing the elongated heat insulating member 2 in the first airbag 12a1, the heat insulating effect of the sealing strip 1 can be enhanced along the length direction, thereby further reducing the heat exchange between the storage cavity and the outside world.

[0040] In one embodiment, the cross-sectional shape of the thermal insulation member 2 along the perpendicular direction matches the cross-sectional shape of the first airbag 12a1 along the perpendicular direction. For example, the cross-sectional shape of the first airbag 12a1 along the perpendicular direction can be a rounded rectangular shape, and the cross-sectional shape of the thermal insulation member 2 along the perpendicular direction can also be a rounded rectangular shape. This shape adaptation increases the volume of the thermal insulation member 2 within the first airbag 12a1, further reducing the overall thermal conductivity of the sealing strip 1 and improving thermal insulation.

[0041] For example, in one embodiment, the rubber material can be nitrile butadiene rubber. By using a suitable rubber material, the brittleness of aerogel can be effectively addressed, reducing the possibility of aerogel being squeezed and damaged during door opening and closing, which could cause the sealing strip 1 to lose its sealing performance. Furthermore, nitrile butadiene rubber has good temperature resistance, allowing the thermal insulation element 2 to maintain stable operation even at relatively low temperatures.

[0042] In one embodiment, the sealing strip 1 includes a connecting member 11 and an elastic support member 12. The connecting member 11 is connected between the door body and the elastic support member 12. The elastic support member 12 is used to abut against the box body. The elastic support member 12 forms an inner cavity 12a. The inner cavity 12a is divided into multiple airbags by dividing ribs A, wherein at least one of the airbags closest to the box body along the thickness direction is the first airbag.

[0043] Here, the elastic support member 12 is connected to the door body through the connecting member 11, which can reduce the situation where the sealing strip 1 falls when opening or closing the door, and improve the working stability of the sealing strip 1. The elastic support member 12 is formed with an inner cavity 12a, and the inner cavity 12a is divided into multiple airbags by the dividing rib A. After the door body closes the access opening, the elastic support member 12 will abut against the box body. On the one hand, when the elastic support member 12 abuts against the box body, the airbags in the elastic support member 12 can play a damping and buffering role between the box body and the door body, reducing the damage caused by the impact between the two. In this way, the service life of the box body and the door body can be improved and the noise when closing the door can be reduced. On the other hand, when the door body is deformed, the volume change of the multiple airbags can be used to compensate for the size of the door body, so as to further reduce the situation where a large gap appears between the door body and the box body. The first airbag 12a1 is located on the side closest to the box body in the thickness direction. In this way, after the door body is closed, the first airbag 12a1 filled with the insulation member 2 will abut against the box body, and the insulation effect is better, thereby further reducing the probability of cold leakage and the energy consumption of the refrigeration equipment.

[0044] For example, in one embodiment, the connecting member 11 is detachably connected to the door body, so that the sealing strip 1 can be easily replaced by the detachable connection.

[0045] For example, in one embodiment, a slot is formed on one of the door body and the connector 11, and a buckle 111 is formed on the other of the door body and the connector 11, and the buckle 111 engages with the slot. For example, the door body can be formed with a slot, and the connector 11 can be formed with a buckle 111. In this way, during installation, the connection between the connector 11 and the door body can be completed by simply snapping the buckle 111 into the slot, which is simple to operate and has good connection stability.

[0046] Exemplarily, in one embodiment, the slot has an inlet and outlet facing the connector 11, and elastic arms 1111 are formed on both side walls of the buckle 111 along the width direction. The buckle 111 enters or exits the slot through the inlet and outlet. When the buckle 111 is in the slot, the elastic arms 1111 abut against the inner wall of the slot, wherein the width direction is perpendicular to the thickness direction. Exemplarily, the two elastic arms 1111 are respectively a first elastic arm 1111a and a second elastic arm 1111b, and the first elastic arm 1111a and the second elastic arm 1111b are respectively arranged on the two side walls of the buckle 111 along the width direction, and the spacing between the first elastic arm 1111a and the second elastic arm 1111b along the width direction gradually decreases from the side close to the connecting member 11 along the thickness direction to the side away from the connecting member 11, so that the buckle 111, the first elastic arm 1111a and the second elastic arm 1111b are roughly arrow-shaped; the shape of the slot is not limited, for example, it can be elliptical, circular or semicircular, etc., and the cross-section of the slot along the perpendicular thickness direction first increases and then decreases from the side close to the connecting member 11 along the thickness direction to the side away from the connecting member 11.

[0047] In this way, when the connecting piece 11 is installed on the door body, the buckle 111 can be inserted into the card slot through the inlet and outlet. When plugging in, since the distance between the first elastic arm 1111a and the second elastic arm 1111b in the width direction gradually decreases from the side close to the elastic support piece 12 along the thickness direction to the side away from the elastic support piece 12, the first elastic arm 1111a and the second elastic arm 1111b form a guide surface along the side surface in the width direction, which facilitates the insertion of the buckle 111 into the inlet and outlet; during the plugging process, the first elastic arm 1111a and the second elastic arm 1111b are relatively small due to the larger diameter of the inlet and outlet. When the door is small, the first elastic arm 1111a and the second elastic arm 1111b will be squeezed by the wall surface at the inlet and outlet to produce elastic deformation; when the buckle 111 is in the card slot, since the cross-section of the card slot along the thickness direction becomes larger, the first elastic arm 1111a and the second elastic arm 1111b will restore the elastic deformation to abut against the inner wall of the card slot. In this way, not only the connection stability between the sealing strip 1 and the door body can be improved, but also the abutment of the first elastic arm 1111a and the second elastic arm 1111b with the inner wall of the card slot can also reduce the situation where the sealing strip 1 has gaps after being installed in the door body, resulting in cold leakage.

[0048] In one embodiment, at least one of the plurality of airbags is a second airbag 12a2 , and the at least one second airbag 12a2 is located between the first airbag 12a1 and the connecting member 11 along the thickness direction.

[0049] For example, the number of second airbags 12a2 can be one, and one second airbag 12a2 can be located between the first airbag 12a1 and the connector 11 along the thickness direction. Of course, the number of second airbags 12a2 can be two or more, and the two or more second airbags 12a2 can be arranged along the thickness direction and located between the connector 11 and the first airbag 12a1. Thus, by positioning the second airbag 12a2 between the first airbag 12a1 and the connector 11 along the thickness direction, when the door is closed, the change in volume within the second airbag 12a2 can act as a damping buffer between the connector 11 and the first airbag 12a1, reducing damage caused by impact between the two.

[0050] In one embodiment, the projection of the first airbag 12a1 along the thickness direction is located within the projection of the second airbag 12a2. In other words, the volume of the first airbag 12a1 is smaller than or equal to the volume of the second airbag 12a2. This ensures that the sealing strip 1 has good thermal insulation while also reducing the filling volume of the thermal insulation member 2, thereby lowering costs.

[0051] It should be noted that Figure 1 R1 can be the thickness direction, and R2 can be the width direction.

[0052] In one embodiment, at least one of the plurality of airbags is a third airbag 12a3, and the at least one third airbag 12a3 is located outside the first airbag 12a1.

[0053] In this way, by setting at least one third airbag 12a3 on the outside of the first airbag 12a1, when the door body closes the access opening, its volume change can be used to compensate for the size of the door body, so as to further reduce the situation where a large gap appears between the door body and the box body.

[0054] In one embodiment, the number of the third airbags 12a3 is two, and the two third airbags 12a3 are arranged on both sides of the first airbag 12a1 along the width direction, wherein the thickness direction is perpendicular to the width direction.

[0055] Exemplarily, the two third airbags 12a3 are a main third airbag 12a31 and a secondary third airbag 12a32, and the main third airbag 12a31 and the secondary third airbag 12a32 are respectively connected to the second airbag 12a2 and the first airbag 12a1 on both sides along the width direction. In this way, when the door body is closed, on the one hand, the third airbag 12a3 can also play a damping and buffering role between the box body and the door body, so as to further reduce the damage caused by the impact between the two. In this way, the service life of the box body and the door body can be improved and the noise when closing the door can be reduced; on the other hand, the volume change of the third airbag 12a3 can be used to compensate for the size of the door body, further reducing the occurrence of a large gap between the door body and the box body.

[0056] Exemplarily, in one embodiment, the shape of the third airbag 12a3 is not limited.

[0057] Exemplarily, in one embodiment, the door body includes a door liner and a door frame, the door frame has a accommodating cavity and an installation port connected to the accommodating cavity, the door liner is arranged in the accommodating cavity through the installation port, the sealing strip 1 is connected to the door liner, and a shielding strip 12a4 is formed on the outer side wall of the main third airbag 12a31 away from the first airbag 12a1 along the width direction, and the shielding strip 12a4 abuts against the installation port.

[0058] It should be noted that when the door liner is installed into the accommodating cavity through the installation port, a gap will appear between the door liner and the installation port due to the size difference. This will not only affect the overall appearance of the refrigeration equipment, but also cause cold leakage at the gap. The present application forms a shielding strip 12a4 on the outer side wall of the main third air bag 12a31 away from the first air bag 12a1 along the width direction. The shielding strip 12a4 abuts against the installation port to block the gap between the door liner and the door frame. In this way, not only the overall appearance of the refrigeration equipment can be improved, but also the probability of cold leakage at the gap can be reduced, thereby reducing the energy consumption of the refrigeration equipment.

[0059] Exemplarily, in one embodiment, a wing edge 12a5 is formed on the outer side wall of the auxiliary third airbag 12a32 away from the main third airbag 12a31 in the width direction, and the wing edge 12a5 abuts against the door liner to further reduce the leakage of cold air from the refrigeration equipment from the gap between the sealing strip 1 and the door liner, so as to improve the sealing between the box body and the door body, and reduce the energy consumption of the refrigeration equipment.

[0060] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, and improvements that fall within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
