DETAILED DESCRIPTION

[0027] 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.

[0028] 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.

[0029] The present application embodiment provides a refrigeration device. Figures 1 to 3 The refrigeration device comprises a box body, a door body 1 and a foam sealing strip 2. The box body is formed with a storage cavity and a take-out port connected to the storage cavity. In this way, when a user needs to take or place an item from the storage cavity through the take-out port, it can be achieved by pulling the door body 1.

[0030] The door body 1 can selectively open or close the access opening. A foam sealing strip 2 is arranged on the door body 1, and an air cavity 2a is formed in the foam sealing strip 2. When the door body 1 closes the access opening, the foam sealing strip 2 abuts against the box body.

[0031] The present application provides a refrigeration device, which can reduce heat conduction and then reduce cold leakage by forming an air cavity 2a in a foam sealing strip 2, so as to save energy consumption of the refrigeration device; on the other hand, when the foam sealing strip 2 abuts against the box, the air cavity 2a in the foam sealing strip 2 can play a damping and buffering role between the door body 1 and the box, reduce the damage caused by the impact between the two, increase the service life of the door body 1 and the box, and reduce the noise of closing the door; on the other hand, when the door body 1 is deformed, the volume change of the air cavity 2a can be used to compensate the size of the door body 1, avoid the situation that a large gap appears between the door body 1 and the box, and improve the sealing performance. The foam sealing strip 2 is used to abut against the box. On the one hand, the foam material has a lower thermal conductivity than the traditional PVC material, and has less heat exchange with the outside world. In this way, it can not only reduce cold leakage and save energy consumption of the refrigeration device, but also reduce condensation under high temperature conditions; on the other hand, the compression fatigue stability of the foam material is high, so that in the long-term opening / closing process and under repeated extrusion conditions, good sealing stability can still be achieved.

[0032] 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 body 1 is also not limited, for example, it can be a rectangle or a square, etc.

[0033] Exemplarily, in one embodiment, the refrigeration device may be a refrigerator or a freezer.

[0034] Exemplarily, in one embodiment, the shape of the foam sealing strip 2 is not limited, for example, it can be a long strip and is arranged on the four sides of the door body 1.

[0035] In one embodiment, the foam sealing strip 2 is formed with an air port connected to the air cavity 2a, and air enters and exits the air cavity 2a through the air port. In this way, when the door body 1 closes the access port, the door body 1 and the box body jointly squeeze the foam sealing strip 2 to make it elastically deformed. At this time, the gas in the air cavity 2a can be released from the air port to buffer the action of the door body 1 closing the access port. In this way, the safety of closing the door can be improved and the noise of closing the door can be reduced, and the user experience is good; after the door body 1 opens the access port, the foam sealing strip 2 can use its own elasticity to restore the deformation, so that the gas can enter the air cavity 2a through the air port to replenish air, so as to prepare for the next time the door body 1 closes the access port.

[0036] In one embodiment, when the door body 1 closes the access opening, the two cavity walls of the air cavity 2a along the thickness direction can fit together. Exemplarily, the shape of the air cavity 2a is not limited, for example, it can be a cube or a cuboid, etc. In this way, when the door body 1 closes the access opening, the door body 1 and the box body will jointly squeeze the foam sealing strip 2 to compress the gas in the air cavity 2a, which can buffer the door body 1 and the box body. When the two cavity walls of the air cavity 2a along the thickness direction fit together, the two cavity walls can abut against each other, which can provide stable support between the box body and the door body 1, and reduce the shaking of the foam sealing strip 2 after the door is closed.

[0037] In one embodiment, please refer to Figures 1 to 3 The cavity walls of the air cavity 2a along the thickness direction are respectively a first cavity wall 2a1 and a second cavity wall 2a2. The first cavity wall 2a1 is formed with a groove 2a11 which is recessed toward the door body 1 along the thickness direction. The second cavity wall 2a2 is formed with a protrusion 2a21 which cooperates with the groove 2a11. When the protrusion 2a21 is located in the groove 2a11, the outer peripheral surface of the protrusion 2a21 is in contact with the groove wall of the groove 2a11. Here, when the door body 1 closes the access port, the door body 1 and the box body will jointly squeeze the foam sealing strip 2, so that the first cavity wall 2a1 and the second cavity wall 2a2 move toward each other, and after the protrusion 2a21 is located in the groove 2a11, the outer peripheral surface of the protrusion 2a21 will fit with the cavity wall of the groove 2a11. On the one hand, through the coordination of the protrusion 2a21 and the groove 2a11, the contact area between the first cavity wall 2a1 and the second cavity wall 2a2 can be increased, so that the combined part can better withstand pressure and torque; on the other hand, the friction between the first cavity wall 2a1 and the second cavity wall 2a2 can be increased to avoid relative movement between the first cavity wall 2a1 and the second cavity wall 2a2 along the width direction, thereby improving the stability of the support.

[0038] In one embodiment, please refer to Figures 1 to 3 , there are multiple grooves 2a11 and multiple protrusions 2a21, and the multiple grooves 2a11 and the multiple protrusions 2a21 are arranged along the width direction, wherein the width direction is perpendicular to the thickness direction. Exemplarily, the number of grooves 2a11 is not limited, for example, the number of grooves 2a11 is four, and the four grooves 2a11 are arranged along the width direction; the number of protrusions 2a21 is also not limited, for example, the number of protrusions 2a21 can be four, and the four protrusions 2a21 are arranged at intervals along the width direction. In this way, by plugging and matching multiple protrusions 2a21 with grooves 2a11, the stability of the support can be further improved.

[0039] It should be noted that the arrangement here can be an interval arrangement or a connection arrangement.

[0040] In one embodiment, a plurality of grooves 2a11 constitute a first sawtooth, a plurality of protrusions 2a21 constitute a second sawtooth, and the first sawtooth can mesh with the second sawtooth. In this way, when the door body 1 closes the access port, the first cavity wall 2a1 and the second cavity wall 2a2 can mesh with the sawtooth. On the one hand, the sawtooth design can greatly reduce the wear between the first cavity wall 2a1 and the second cavity wall 2a2, and enhance its wear resistance; on the other hand, the sawtooth design can make the stress distribution generated by the first cavity wall 2a1 and the second cavity wall 2a2 when bearing the load applied by the box body and the door body 1 more uniform, thereby avoiding stress concentration, which helps to improve the fatigue resistance of the first cavity wall 2a1 and the second cavity wall 2a2.

[0041] For example, in one embodiment, please refer to Figures 1 to 3 Two of the four grooves 2a11 are connecting grooves 2a111, and the other two are transition grooves 2a112. The two connecting grooves 2a111 are arranged along the width direction, and the two transition grooves 2a112 are respectively arranged at the two ends of the two connecting grooves 2a111 along the width direction. The angle formed by the two groove walls of the connecting groove 2a111 is greater than the angle formed by the two groove walls of the transition groove 2a112. The sizes of the two groove walls of the connecting groove 2a111 are the same. The size of the left groove wall of the transition groove 2a112 on the left side along the width direction is greater than the size of the right groove wall, and the size of the left side wall of the transition groove 2a112 on the right side along the width direction is smaller than the size of the right groove wall. In this way, the protrusion 2a21 can avoid structural interference when inserted into the groove 2a11 and the engagement is more stable.

[0042] Illustratively, in one embodiment, the plurality of grooves 2a11 and the plurality of protrusions 2a21 may all be in a wave shape or other shapes, specifically, so as to be able to fit together when meshed up and down.

[0043] In one embodiment, please refer to Figure 2 The refrigeration device includes a magnetic member 3 for magnetically cooperating with the box body. The magnetic member 3 is arranged on the side of the foam sealing strip 2 away from the door body 1. In this way, when the door body 1 is pulled to close the access port, the magnetic member 3 can connect the door body 1 and the box body by magnetically cooperating with the box body and squeeze the foam sealing strip 2 located therebetween to achieve a sealing effect.

[0044] In one embodiment, please refer to Figure 3 , the magnetic attraction parts 3 are arranged at both ends of the foam sealing strip 2 in the width direction. For example, taking the refrigeration device as a refrigerator, the magnetic attraction parts 3 can be arranged at both ends of the foam sealing strip 2 in the width direction and at one end away from the door body 1 in the thickness direction. In this way, it will not affect the magnetic attraction cooperation between the magnetic attraction parts 3 and the box body, and can also ensure that the foam sealing strip 2 has a sufficient thickness in a limited installation space to further improve the heat insulation effect.

[0045] In one embodiment, the magnetic attraction member 3 and the foam sealing strip 2 are co-extruded and formed. In this way, the foam sealing strip 2 and the magnetic attraction member 3 can realize magnetic plastic integration through the co-extrusion process, which can not only save post-processing steps, but also can be squeezed by the magnetic attraction of the box body to fill the gap between the box body and the door body 1, further improving the sealing between the box body and the door body 1.

[0046] In one embodiment, the foam sealing strip 2 is detachably connected to the door body 1. In this way, the foam sealing strip 2 is easily replaced through the detachable connection.

[0047] In one embodiment, please refer to Figures 1 to 3 , one of the door body 1 and the foam sealing strip 2 is formed with a slot 1a, and the other of the door body 1 and the foam sealing strip 2 is formed with a buckle 2b, and the buckle 2b is engaged with the slot 1a. Exemplarily, the door body 1 can be formed with a slot 1a, and the foam sealing strip 2 can be formed with a buckle 2b, so that during installation, the connection between the foam sealing strip 2 and the door body 1 can be completed by simply buckling the buckle 2b in the slot 1a, which is simple to operate and has good connection stability.

[0048] In one embodiment, please refer to Figures 1 to 3 The card slot 1a has an inlet and outlet 1b facing the foam sealing strip 2, the groove wall surface of the card slot 1a along the width direction forms a first step surface 1c, and the surface of the buckle 2b along the width direction forms a second step surface 2c. The buckle 2b enters or escapes from the card slot 1a through the inlet and outlet 1b. When the buckle 2b is located in the card slot 1a, the first step surface 1c abuts against the side of the second step surface 2c close to the foam sealing strip 2.

[0049] Exemplarily, the card slot 1a includes a first limiting groove 1a1 and a second limiting groove 1a2, the second limiting groove 1a2 is connected to an end of the first limiting groove 1a1 close to the inlet and outlet 1b along the thickness direction, the width of the first limiting groove 1a1 gradually increases from the side close to the inlet and outlet 1b along the thickness direction to the side away from the inlet and outlet 1b, so as to be roughly triangular, the width of the second limiting groove 1a2 is roughly constant from the side close to the inlet and outlet 1b along the thickness direction to the side away from the inlet and outlet 1b, the width of the second limiting groove 1a2 is smaller than the maximum width of the first limiting groove 1a1, so that the card slot 1a is roughly arrow-shaped, and the first step surface 1c is formed between the first limiting groove 1a1 and the second limiting groove 1a2; the buckle 2b includes a first clip part 2b1 and a second clip part 2b2, the first clip part 2b1 is connected to an end of the second clip part 2b2 close to the door body 1 along the thickness direction, the width of the first clip part 2b1 gradually increases from the side close to the door body 1 along the thickness direction to the side away from the door body 1, so as to be roughly triangular, the width of the second clip part 2b2 is roughly unchanged from the side close to the door body 1 along the thickness direction to the side away from the door body 1, the width of the second clip part 2b2 is smaller than the maximum width of the first clip part 2b1, so that the buckle 2b is roughly arrow-shaped, and a second step surface 2c is formed at the connection between the first clip part 2b1 and the second clip part 2b2.

[0050] Here, when the elastic sealing strip is installed on the door body 1, the buckle 2b can be inserted into the slot 1a through the inlet and outlet 1b. When plugging in, since the width of the first clip part 2b1 gradually increases from the side close to the door body 1 along the thickness direction to the side away from the door body 1, the first clip part 2b1 forms guide surfaces along the two sides of the width, which facilitates the guidance of the clip 2b for plugging in; when the buckle 2b is located in the slot 1a, the first clip part 2b1 is located in the first limiting groove 1a1, the second clip part 2b2 is located in the second limiting groove 1a2, and the first step surface 1c abuts against the side of the second step surface 2c close to the foam sealing strip 2. In this way, the contact area between the buckle 2b and the slot 1a can be increased to further improve the connection stability between the foam sealing strip 2 and the door body 1.

[0051] Exemplarily, in one embodiment, the foam sealing strip 2 may be made of a closed-cell micro-foam material, which has the characteristics of low water absorption, good cushioning properties, and good temperature resistance.

[0052] In one embodiment, the material of the foam sealing strip 2 is PU (polyurethane), TPE (thermoplastic elastomer) or EPDM (ethylene propylene diene monomer rubber). Exemplarily, the material of the foam sealing strip 2 can be PU, specifically, TPU (thermoplastic polyurethane). On the one hand, the production cost of PU foam material is relatively low; on the other hand, PU has excellent thermal insulation performance, which can effectively improve the cold leakage phenomenon of refrigeration equipment, thereby reducing the energy consumption of refrigeration equipment; on the other hand, PU has good chemical stability, which can resist the corrosion of acid, alkali, grease and other chemicals in the storage cavity to a certain extent. The material of the foam sealing strip 2 can also be TPE. On the one hand, TPE has a lower specific gravity, so the weight of the foam sealing strip 2 can be reduced, and lightweight, energy-saving and environmentally friendly can be achieved; on the other hand, TPE is physically foamed and does not undergo chemical reactions, so the material composition will not be changed, ensuring its resilience; on the other hand, the raw materials of TPE foam material do not contain harmful substances such as plasticizers and vulcanization aids, and have low odor and are safe and environmentally friendly. The material of the foam sealing strip 2 can also be EPDM. On the one hand, EPDM can maintain good elasticity and good stability in a wide temperature range; on the other hand, EPDM can maintain its performance under the action of a variety of chemical substances and has good chemical corrosion resistance; on the other hand, EPDM also has good anti-aging performance, low temperature performance, heat resistance and compression fatigue stability, which enables the foam sealing strip 2 to ensure the sealing stability during the long-term closing and opening of the door body 1 and the access port.

[0053] 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.
