DETAILED DESCRIPTION
[0026] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present 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 the present application and should not be regarded as an improper limitation on the present application.
[0027] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are only for descriptive purposes and cannot 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, such as two, three, etc., unless otherwise clearly and specifically limited.
[0028] In order to reduce cold leakage, the related technology adds an auxiliary airbag to the sealing strip. However, the airbag chamber of the auxiliary airbag cannot play the role of heat insulation due to the small gap between the door body and the box body and the limitation of its own material.
[0029] In view of this, the present application embodiment provides a refrigeration device, please refer to Figure 1 and Figure 2 The refrigeration device 100 includes a box body 1, a door body 2, a sealing strip 3 and an auxiliary support member 4. The box body 1 is formed with a storage cavity and a take-in and put-out port connected to the storage cavity. The door body 2 can selectively open or close the take-in and put-out port. One side of the sealing strip 3 along the thickness direction is connected to the door body 2, and the other side of the sealing strip 3 along the thickness direction is used to abut against the box body 1. When the door body 2 closes the take-in and put-out port, the auxiliary support member 4 is arranged between the box body 1 and the door body 2, and the auxiliary support member 4 is filled with a heat insulating material 5.
[0030] The embodiment of the present application provides a refrigeration device 100. By setting a sealing strip 3 between the box body 1 and the door body 2, not only can the gap between the box body 1 and the door body 2 be sealed to reduce the cold leakage of the box body 1, but also the door body 2 and the box body 1 can play a buffering role, reduce the damage caused by the impact between the two, increase the service life of the box body 1 and the door body 2, and reduce the noise of closing the door. By setting an auxiliary support member 4, when the door body 2 is closed, the auxiliary support member 4 can be located between the box body 1 and the door body 2, so that the damage caused by the impact between the door body 2 and the box body 1 can be further reduced, the service life of the box body 1 and the door body 2 can be increased, and the noise of closing the door can be reduced. By filling the auxiliary support member 4 with the thermal insulation material 5, on the one hand, the overall thermal conductivity of the auxiliary support member 4 can be reduced, the thermal resistance can be increased, and the heat exchange between the storage cavity and the outside world can be further reduced, the thermal insulation effect is good, and the energy consumption of the refrigeration equipment 100 is low; on the other hand, since the thermal insulation material 5 is filled into the auxiliary support member 4, this can not only reduce the filling of the thermal insulation material 5 in the sealing strip 3, and then reduce the damage to the structural function of the sealing strip 3 caused by too much filling of the thermal insulation material 5, so as to reduce the influence on the compensation and sealing effect of the sealing strip 3, but also set the auxiliary support member 4 and fill the thermal insulation material 5 inside it, the process is relatively simple and feasible.
[0031] For example, in one embodiment, the shape of the box body 1 is not limited, for example, it can be a cuboid or a cube, etc. The shape of the door body 2 is also not limited, for example, it can be a rectangle or a square, etc.
[0032] Illustratively, in one embodiment, the refrigeration device 100 may be a refrigerator or a freezer.
[0033] It should be noted that Figure 1 R1 may be the thickness direction, and R2 may be the width direction.
[0034] In one embodiment, the heat insulating material 5 is an open-pore high-resilience sponge. On the one hand, the open-pore high-resilience sponge has excellent heat insulating properties, can effectively reduce the heat exchange between the storage cavity and the outside world, has a small amount of cold leakage, and has low energy consumption of the refrigeration device 100; on the other hand, the open-pore high-resilience sponge also has good elasticity and durability, so that it can not only reduce the impact of the box body 1 and the door body 2 when closing the door, and improve the service life of the box body 1 and the door body 2, but also improve the working stability of the auxiliary support 4 due to its good durability; on the other hand, the open-pore structure of the open-pore high-resilience sponge makes it easier to adapt to the internal space of the auxiliary support 4, thereby improving the sealing performance of the auxiliary support 4.
[0035] Exemplarily, in one embodiment, the material of the open-cell high resilience sponge is polyurethane foam (PU) or chemical cross-linked polyethylene foam (XPE). Exemplarily, the material of the open-cell high resilience sponge can be polyurethane foam. On the one hand, the polyurethane foam has a low thermal conductivity, which can effectively reduce the amount of cold leakage, so that the storage cavity maintains a low working environment; on the other hand, the polyurethane foam has good shock resistance and softness, which enables it to provide effective sealing while reducing the vibration and impact of the refrigeration equipment 100 during transportation and closing. In other embodiments, the material of the open-cell high resilience sponge can also be chemical cross-linked polyethylene foam. On the one hand, the chemical cross-linked polyethylene foam has a good thermal insulation effect, which can effectively reduce the heat exchange between the storage cavity and the outside world and reduce the amount of cold leakage; on the other hand, the chemical cross-linked polyethylene foam has good waterproof and moisture-proof properties, can maintain stable performance in a humid environment, and has good working stability; on the other hand, the chemical cross-linked polyethylene foam can resist the erosion of corrosive substances such as acids and alkalis and the corrosion of chemicals, so as to maintain stable performance in a variety of environments.
[0036] In one embodiment, the heat insulating material 5 is a closed-cell elastic sponge. On the one hand, the closed-cell structure of the closed-cell elastic sponge makes the thermal conductivity of the gas inside it low, thereby obtaining a good heat insulation effect, thereby reducing the heat exchange between the storage cavity and the outside, reducing the cold leakage and the energy consumption of the refrigeration device 100; on the other hand, the closed-cell elastic sponge has good durability and anti-extrusion performance, can withstand the extrusion and friction when the door is frequently closed, and has good working stability.
[0037] For example, in one embodiment, the closed-cell elastic sponge is made of ethylene propylene diene monomer (EPDM). On the one hand, EPDM has good aging resistance, which means that EPDM can be used for a long time in various environments with good working stability; on the other hand, EPDM has high elasticity and softness, which can improve the sealing of the auxiliary support member 4 to reduce the cold leakage of the refrigeration device 100.
[0038] In one embodiment, the thermal insulation material 5 is aerogel. Exemplarily, the aerogel may be aerogel powder, aerogel coating or aerogel paste. On the one hand, aerogel has a low thermal conductivity, and therefore can effectively block the transfer of heat and improve the thermal insulation performance of the refrigeration device 100; on the other hand, the weight of aerogel is relatively light, which helps to reduce the mass of the auxiliary support member 4, and then can reduce the burden on the refrigeration device 100.
[0039] In one embodiment, the heat insulating material 5 is a micro-foam of a thermoplastic elastomer. On the one hand, the micro-foam of the thermoplastic elastomer has high elasticity, can effectively fill the space in the auxiliary support 4, ensure better heat insulation effect, and can also adapt to the deformation of the auxiliary support 4, extending its service life; on the other hand, the micro-foam of the thermoplastic elastomer has good wear resistance, corrosion resistance and aging resistance, can maintain a long-term heat insulation effect without deformation or damage, and improve the service life of the auxiliary support 4.
[0040] Exemplarily, in one embodiment, the shape of the auxiliary support member 4 is not limited. For example, the auxiliary support member 4 may be in the shape of a cylindrical strip, and the interior of the cylindrical strip is filled with a heat insulating material 5 .
[0041] In one embodiment, please refer to Figure 1 and Figure 2 The sealing strip 3 includes a connecting member 31 and an elastic supporting member 32. The connecting member 31 is connected between the door body 2 and the elastic supporting member 32. The elastic supporting member 32 is used to abut against the box body 1. The elastic supporting member 32 forms an inner cavity 32a.
[0042] Exemplarily, the elastic support member 32 is connected to the door body 2 through the connecting member 31, which can reduce the situation that the sealing strip 3 falls off when opening or closing the door, and improve the working stability of the sealing strip 3. By forming an inner cavity 32a in the elastic support member 32, the elastic support member 32 will abut against the box body 1 after the door body 2 closes the access port. On the one hand, when the elastic support member 32 abuts against the box body 1, the inner cavity 32a in the elastic support member 32 can play a damping and buffering role between the box body 1 and the door body 2, reducing the damage caused by the impact between the two, so that the service life of the box body 1 and the door body 2 can be improved and the noise when closing the door can be reduced; on the other hand, when the door body 2 is deformed, the volume change of the inner cavity 32a can be used to compensate for the size of the door body 2, so as to reduce the situation that a large gap appears between the door body 2 and the box body 1.
[0043] For example, in one embodiment, please refer to Figure 1 and Figure 2The inner cavity 32a can be divided into a first airbag 32a1, a second airbag 32a2 and a third airbag 32a3 by a dividing rib. The first airbag 32a1 is connected to the side of the second airbag 32a2 away from the door body 2 in the thickness direction. The number of the third airbag 32a3 can be two, and the two third airbags 32a3 are respectively located on one side of the first airbag 32a1 and the second airbag 32a2 in the width direction. In this way, when the door body 2 is closed, the first airbag 32a1, the second airbag 32a2 and the third airbag 32a3 can all play a damping and buffering role between the box body 1 and the door body 2 to reduce the damage caused by the impact between the two. In this way, the service life of the box body 1 and the door body 2 can be improved and the noise when closing the door can be reduced; when the door body 2 is deformed, the volume changes of the first airbag 32a1, the second airbag 32a2 and the third airbag 32a3 can be used to compensate for the size of the door body 2, thereby further reducing the situation where a large gap appears between the door body 2 and the box body 1.
[0044] In one embodiment, please refer to Figure 1 and Figure 2 The door body 2 includes a door frame 21 and a door liner 22, the door liner 22 is arranged in the door frame 21, a slot 22a is formed in one of the connecting piece 31 and the door liner 22, and a buckle 31a is formed in the other of the connecting piece 31 and the door liner 22, and the buckle 31a is engaged with the slot 22a. When the door body 2 is closed to open and close the access opening, the auxiliary support member 4 abuts between the box body 1 and the door liner 22, and the elastic support member 32 abuts against the box body 1.
[0045] Exemplarily, the box body 1 includes a box shell and a box liner, and the box liner is located in the box shell. The connector 31 may be formed with a buckle 31a, and the door liner 22 may be formed with a slot 22a, so that during installation, the buckle 31a only needs to be buckled into the slot 22a to complete the connection between the connector 31 and the door liner 22, which is simple to operate and has good connection stability. When the door body 2 is closed, the auxiliary support member 4 can be abutted between the box liner and the door liner 22 to increase the thermal resistance at the gap between the box liner and the door liner 22, thereby reducing the amount of cold leakage and the energy consumption of the refrigeration device 100.
[0046] For example, in one embodiment, please refer to Figure 1 and Figure 2 The door frame 21 is formed with a accommodating cavity and an installation opening connected to the accommodating cavity. The door liner 22 is arranged in the accommodating cavity through the installation opening. A shielding strip 7 is formed on the outer side wall of the third airbag 32a3 close to the door frame 21 along the width direction, and the shielding strip 7 abuts against the installation opening.
[0047] It should be noted that when the door liner 22 is installed into the accommodating cavity through the installation opening, a gap will appear between the door liner 22 and the installation opening due to the size difference. This will not only affect the overall appearance of the refrigeration device 100, but also cause cold leakage at the gap. The present application forms a shielding strip 7 on the outer side wall of the third air bag 32a3 close to the door frame 21 along the width direction, and the shielding strip 7 abuts against the installation opening to block the gap between the door liner 22 and the door frame 21. In this way, not only the overall appearance of the refrigeration device 100 can be improved, but also the probability of cold leakage at the gap can be reduced, thereby reducing the energy consumption of the refrigeration device 100.
[0048] For example, in one embodiment, please refer to Figure 1 and Figure 2 A wing edge 8 is formed on the outer side wall of the third air bag 32a3 close to the door frame 21 along the width direction, and the wing edge 8 and the shielding strip 7 are arranged at intervals along the thickness direction. When the door body 2 is closed for taking and placing, the wing edge 8 abuts against the box liner to further reduce the leakage of cold air of the refrigeration equipment 100 from the gap between the sealing strip 3 and the box liner, so as to improve the sealing between the box body 1 and the door body 2, and reduce the energy consumption of the refrigeration equipment 100.
[0049] In one embodiment, please refer to Figure 1 and Figure 2 The sealing strip 3 and the auxiliary support member 4 are arranged along the width direction, wherein the thickness direction is perpendicular to the width direction.
[0050] Exemplarily, the sealing strip 3 can be arranged on the side of the auxiliary support member 4 away from the door frame 21 in the width direction. In this way, the heat transfer path can be extended in the width direction, and the thermal resistance at the gap formed between the door body 2 and the box body 1 when closed can be increased, thereby reducing the cold leakage between the box body 1 and the door body 2, thereby reducing the energy consumption of the refrigeration equipment 100.
[0051] In one embodiment, please refer to Figure 1 The slot 22a has an inlet and outlet 22b facing the connecting piece 31. The refrigeration device 100 includes a buffer pad 6, which is arranged at the periphery of the inlet and outlet 22b. The buckle 31a enters or escapes from the slot 22a through the inlet and outlet 22b. When the buckle 31a is located in the slot 22a, the portion of the sealing strip 3 located at the inlet and outlet 22b abuts against the buffer pad 6.
[0052] Exemplarily, taking the example of the connector 31 having a card slot 22a and the door liner 22 having a card slot 22a, the buffer pad 6 can be arranged in the card slot 22a at the inlet and outlet 22b and on the periphery of the inlet and outlet 22b on the side away from the card slot 22a in the thickness direction. When the buckle 31a is located in the card slot 22a, the portion of the connector 31 located in the card slot 22a and the portion of the elastic support member 32 in contact with the door liner 22 are both blocked by the buffer pad 6. In this way, the contact area between the sealing strip 3 and the door liner 22 can be reduced, and then the deformation caused by direct impact with the door liner 22 can be reduced. In this way, not only can the damage to the door liner 22 be reduced and the service life of the door liner 22 be improved, but the provision of the buffer pad 6 also facilitates the installation of the sealing strip 3.
[0053] In one embodiment, the auxiliary support member 4 is integrally formed with the buffer pad 6. On the one hand, the connection strength between the auxiliary support member 4 and the buffer pad 6 can be improved, and the stability is good; on the other hand, the auxiliary support member 4 is integrally formed with the buffer pad 6, and can be used as a separate part and arranged on the door body 2 or the box body 1. When the door body 2 is closed and the access opening is closed, the auxiliary support member 4 is abutted between the box body 1 and the door body 2, and the installation is convenient.
[0054] In one embodiment, the buffer pad 6 and the auxiliary support member 4 are formed by soft-hard co-extrusion, which not only saves process cost but also has good bonding properties to improve the overall performance and stability of the product.
[0055] In one embodiment, the auxiliary support member 4 is connected to the sealing strip 3, for example, it can be co-extruded with the sealing strip 3. In this way, the auxiliary support member 4 can be indirectly connected to the door body 2 through the sealing strip 3. When the door body 2 closes the access opening, the auxiliary support member 4 and the sealing strip 3 can both abut between the box body 1 and the door body 2. When the door body 2 opens the access opening, the auxiliary support member 4 can be connected to the door body 2 through the sealing strip 3 and is not easy to fall off.
[0056] In one embodiment, the auxiliary support member 4 is connected to the door body 2. That is, the auxiliary support member 4 can be directly connected to the door body 2, and is not easy to fall off when the door body 2 is opened.
[0057] In one embodiment, the buffer pad 6 is formed by hard extrusion of polypropylene. Here, the buffer pad 6 is hard extruded to make it have a higher structural strength, so that it is easy to install the installation strip. Polypropylene is used as the material of the buffer pad 6. On the one hand, polypropylene has high strength, rigidity, toughness and elongation ductility, and can withstand the impact and extrusion when the sealing strip 3 is installed to reduce damage to the door liner 22; on the other hand, polypropylene has good weather resistance and can work stably in a low temperature environment.
[0058] In one embodiment, the auxiliary support member 4 is formed by soft extrusion of a thermoplastic elastomer. On the one hand, the soft extrusion can be customized according to different models and sizes of the refrigeration equipment 100, thereby improving the closeness between the auxiliary support member 4 and the refrigeration equipment 100 and reducing the amount of cold leakage; on the other hand, the thermoplastic elastomer has good elasticity, and while playing a role in heat insulation and heat preservation, it can also further improve the buffer between the box body 1 and the door body 2, reducing the damage caused by the impact between the two; on the other hand, the thermoplastic elastomer also has good temperature resistance and anti-aging performance, which can not only adapt to the relatively harsh temperature environment in the storage cavity, but also effectively resist the corrosion of various chemical substances.
[0059] Exemplarily, in one embodiment, the buffer pad 6 and the sealing strip 3 may be formed by co-extrusion.
[0060] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present application are included in the protection scope of the present application.
