Description

Technical Field

[0001] The embodiments of the present application relate to the field of household appliance technology, and in particular, to a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature.

[0003] In the related art, a refrigerator includes a box body and a door body, a storage chamber is defined in the box body, a guide is provided on the inner top wall of the box body, and the door body is provided on the front surface to close and open the storage chamber. The door body includes a first door body and a second door body that are relatively opened, and the first door body includes a main body and a flip beam assembly that is rotatably connected to the main body. When the first door body is opened, the flip beam assembly is in a flipped state under the action of the guide, that is, the flip beam assembly rotates to be perpendicular to the door surface and is attached to the side of the first door body, so as to facilitate users to store and retrieve items. When the first door body is closed, the flip beam assembly rotates under the action of the guide and is parallel to the door surface of the first door body to seal the gap between the door body and the box body, thereby effectively avoiding cold leakage.

[0004] However, when the first door body is opened and closed, the flip beam assembly collides with the inner wall of the guide member, generating a relatively large noise. Utility Model Content

[0005] The embodiment of the present application provides a refrigerator with low noise.

[0006] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0007] A box body, the box body defining a storage chamber;

[0008] A door body, which is connected to the box body to open or close the storage room, and includes a first door body and a second door body that are relatively open, and the first door body includes a main body and a flip beam assembly connected to the main body;

[0009] The guide member is connected to the box body and is arranged on the top of the storage room. The guide member includes:

[0010] A guide body, wherein the guide body has a guide cavity;

[0011] An acoustic black hole vibration reduction structure is connected to the guide member body, and at least part of the inner wall of the guide cavity is formed by the acoustic black hole vibration reduction structure.

[0012] In this way, the flip beam assembly moves in the guide cavity. When the flip beam assembly collides with the acoustic black hole vibration reduction structure, due to the energy gathering effect of the acoustic black hole, the bending wave enters the acoustic black hole vibration reduction structure, the wave speed decreases, the wave amplitude increases, and the energy is gathered to the center of the black hole structure. At this time, the acoustic black hole vibration reduction structure converts the vibration energy into heat energy dissipation through deformation, which increases the structural loss factor, increases the dissipated vibration energy, and improves the vibration reduction effect.

[0013] In some embodiments of the present application, the acoustic black hole vibration reduction structure includes an acoustic black hole body and a vibration reduction member;

[0014] The acoustic black hole body is connected to the guide member body, and the acoustic black hole body includes a plurality of curve gradient segments which are smoothly transitioned and connected in sequence, and a side of the curve gradient segment facing the guide cavity forms an inner wall surface of the guide cavity;

[0015] Along the length direction of the box body, from the side close to the guide body to the side far from the guide body, the projection area of ​​the curved gradient section toward the ground gradually decreases;

[0016] The vibration-damping component is connected to a side of the curved gradient section away from the guide component body.

[0017] In this way, the reliability of the connection between the curved gradient section and the guide member body can be improved.

[0018] In some embodiments of the present application, the vibration damping member is embedded in a side of the acoustic black hole body facing away from the guide cavity, and the vibration damping member abuts against the side of the acoustic black hole body facing away from the guide cavity.

[0019] In this way, the strength of the acoustic black hole body can be improved and damage to the acoustic black hole body can be effectively avoided.

[0020] In some embodiments of the present application, along the length direction of the box, the length dimension of the vibration damping member is not less than half of the length dimension of the acoustic black hole body.

[0021] In this way, the strength of the acoustic black hole itself can be increased.

[0022] In some embodiments of the present application, along the length direction of the box, the length dimension of the vibration damping member is equal to the length dimension of the acoustic black hole body.

[0023] In this way, the strength of the acoustic black hole itself can be increased.

[0024] In some embodiments of the present application, the boundary curve formed by the projection of the surface of each curved gradient segment away from the vibration damping member toward the corresponding first plane conforms to the following formula:

[0025] Y=aX b

[0026] Wherein, b is not less than 2;

[0027] Wherein, the plane perpendicular to the tangent line of the orthographic projection of the curve gradient segment toward the ground is the corresponding first plane;

[0028] The origin position is the end point of the boundary curve away from the guide body;

[0029] Where X is the distance from the origin along the length direction of the box;

[0030] Wherein, Y is the distance from the origin along a direction perpendicular to the length direction of the box and parallel to the corresponding first plane.

[0031] In this way, the overall structure of the acoustic black hole body is relatively simple and easy to implement.

[0032] In some embodiments of the present application, the vibration damping member includes a vibration damping body and a first limiting structure disposed on a side of the vibration damping body facing the guide member body;

[0033] The guide member body is provided with a second limiting structure matching the first limiting structure, and the first limiting structure is clamped with the second limiting structure.

[0034] In this way, the vibration damping member can be effectively prevented from falling off the guide member body.

[0035] In some embodiments of the present application, the guide body has an inlet and an outlet, the inlet and the outlet are connected to the guide cavity, and the flip beam assembly enters and exits the guide cavity through the inlet and the outlet;

[0036] On a side of the guide cavity that is away from the inlet and outlet along the extension direction of the guide cavity, the inner wall of the guide cavity is formed by an acoustic black hole vibration reduction structure.

[0037] In this way, the collision noise between the tipping beam assembly and the end position of the guide cavity can be reduced.

[0038] In some embodiments of the present application, the inner walls of the guide cavity are formed by an acoustic black hole vibration reduction structure.

[0039] In this way, the overall vibration reduction and noise reduction effect can be improved.

[0040] In a second aspect, an embodiment of the present application provides a refrigerator, comprising:

[0041] Box;

[0042] The door body is connected with the box body, and the door body includes a flip beam assembly;

[0043] The guide piece is connected with the box body and includes:

[0044] A guide body, wherein the guide body has a guide cavity;

[0045] The acoustic black hole vibration reduction structure is connected to the guide member body, and at least part of the inner wall of the guide cavity is formed by the acoustic black hole vibration reduction structure.

[0046] In this way, the flip beam assembly moves in the guide cavity. When the flip beam assembly collides with the acoustic black hole vibration reduction structure, due to the energy gathering effect of the acoustic black hole, the bending wave enters the acoustic black hole vibration reduction structure, the wave speed decreases, the wave amplitude increases, and the energy is gathered to the center of the black hole structure. At this time, the acoustic black hole vibration reduction structure converts the vibration energy into heat energy dissipation through deformation, which increases the structural loss factor, increases the dissipated vibration energy, and improves the vibration reduction effect.

[0075] See also Figure 1 As shown, when the first door is closed, the guide post of the flip beam assembly enters the guide cavity 311 through the inlet and outlet 312 of the guide member, and the guide post abuts against the inner wall of the guide cavity 311. The guide post slides along the inner wall of the guide cavity 311 to rotate the flip beam assembly until it is parallel to the door surface of the first door. Therefore, when the first door is closed, the guide post of the flip beam assembly collides with the inner wall of the guide cavity 311, generating noise. It is understandable that when the first door is closed, the impact force of the flip beam assembly colliding with the end position of the guide cavity 311 (the position shown by the dotted line in the figure) is relatively large, and the noise generated is relatively large.

[0076] Similarly, when the first door is opened, the guide post of the flip beam assembly abuts against the inner wall of the guide cavity 311, and the guide post slides along the inner wall of the guide cavity 311, so that the flip beam assembly rotates until it is perpendicular to the door surface of the first door. Therefore, the guide post of the flip beam assembly is prone to collide with the inner wall of the guide cavity 311, generating noise.

[0077] In order to solve the above technical problems, in the refrigerator provided in the present application, at least part of the inner wall of the guide cavity of the guide member is formed by an acoustic black hole vibration reduction structure, which can play a role in vibration reduction and noise reduction, thereby reducing noise.

[0083] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0084] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0085] See also Figures 2 to 4 As shown, this embodiment provides a refrigerator, including a cabinet 100, a door 200, a guide member 300 and a refrigeration system (not shown in the figure).

[0086] The box body 100 may define a storage room and a press chamber. There may be at least one storage room. When the number of the storage rooms is one, the storage room may be any one of a refrigerating room, a freezing room, or a temperature-changing room. When the number of the storage rooms is two or more, the plurality of storage rooms may include at least one or more of a refrigerating room, a freezing room, or a temperature-changing room.

[0087] The refrigeration system may include a compressor, a condenser, a throttling device and an evaporator, wherein the compressor, the condenser, the throttling device and the evaporator are connected in series in sequence through a pipeline, and a refrigerant flows in the pipeline. The compressor and the condenser may be arranged in a compressor compartment, and the evaporator may be arranged in a storage room.

[0088] When the compressor is working, low-temperature, low-pressure refrigerant is sucked into the compressor, compressed into high-temperature, high-pressure superheated gas in the cylinder of the compressor, and then discharged into the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, the temperature continues to drop, and is gradually cooled to a saturated vapor at normal temperature and high pressure, and further cooled to a saturated liquid. The pressure of the refrigerant remains almost unchanged during the entire condensation process. The throttling device may include a pressure reducing tube or an electronic expansion valve. In this application, the throttling device includes a pressure reducing tube as an example for description. The pressure reducing tube has low cost and is not prone to abnormal failure. The condensed refrigerant saturated liquid is throttled and depressurized through the pressure reducing tube, and the refrigerant becomes a wet vapor at normal temperature and low pressure. Afterwards, the wet vapor at normal temperature and low pressure absorbs heat and vaporizes through the evaporator, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The evaporator cools the air in the storage room to reduce the temperature of the storage room. The refrigerant coming out of the evaporator returns to the compressor again, and the above process is repeated, so that the evaporator can continue to cool the air in the storage room, thereby maintaining the storage room at the set temperature.

[0089] In some embodiments, the refrigeration system may further include a drying filter, which is connected between the condenser and the throttling device through a pipeline, and the drying filter can filter out moisture and impurities in the refrigerant.

[0090] See also Figure 3 and Figure 4 As shown, the door body 200 is connected to the box body 100 to open or close the storage chamber, and the door body 200 includes a first door body 210 and a second door body 220 that are opened relatively.

[0091] Specifically, the first door body 210 and the second door body 220 are arranged along the width direction ( Figure 3 The first door body 210 and the second door body 220 are arranged side by side (in the direction shown by the X-axis), the first door body 210 and the second door body 220 are both hinged to the box body 100, the side of the first door body 210 away from the second door body 220 is hinged to the box body 100, and the side of the second door body 220 away from the first door body 210 is hinged to the box body 100. Among them, the first door body 210 includes a body 211 and a flip beam assembly 212 connected to the body 211. During the opening process of the first door body 210, the flip beam assembly 212 rotates from a state parallel to the door surface of the body 211 to a vertical state. During the closing process of the first door body 210, the flip beam assembly 212 rotates from a state vertical to a state parallel to the door surface of the body 211, which is beneficial to the sealing of the door body 200 and the box body 100.

[0092] In some embodiments, the guide member 300 is connected to the box body 100 and is disposed on the top of the storage chamber.

[0093] See also Figures 5 to 8 As shown, the guide member 300 includes: a guide member body 310 and an acoustic black hole vibration reduction structure 320 .

[0094] The guide body 310 has a guide cavity 311 .

[0095] The acoustic black hole vibration reduction structure 320 is connected to the guide member body 310 , and at least part of the inner wall of the guide cavity 311 is formed by the acoustic black hole vibration reduction structure 320 .

[0096] It can be understood that when the flip beam assembly 212 moves in the guide cavity 311 and collides with the acoustic black hole vibration reduction structure 320, due to the energy gathering effect of the acoustic black hole, the bending wave enters the acoustic black hole vibration reduction structure 320, the wave speed decreases, the wave amplitude increases, and the energy is gathered to the center of the black hole structure. At this time, the acoustic black hole vibration reduction structure 320 converts the vibration energy into heat energy dissipation through deformation, so that the structural loss factor is increased, the dissipated vibration energy is increased, and the vibration reduction effect is improved.

[0097] In some embodiments, the guide body 310 has an inlet and outlet 312 , which is connected to the guide cavity 311 , and the flip beam assembly 212 enters and exits the guide cavity 311 through the inlet and outlet 312 .

[0098] like Figure 1 As shown, when the first door is closed, the end position of the flip beam assembly 212 and the guide cavity 311 ( Figure 1 The impact force of the collision is greater and the noise generated is greater.

[0099] Therefore, in order to reduce the collision noise between the tip of the flip beam assembly 212 and the end of the guide cavity 311, in this embodiment, the inner wall of the guide cavity 311 is formed by an acoustic black hole vibration reduction structure 320 on the side away from the inlet and outlet 312 along the extension direction of the guide cavity 311. The extension direction of the guide cavity 311 is the moving direction of the flip beam assembly 212 after entering the guide cavity 311.

[0100] It should be noted that the inner wall of the guide cavity 311 in other areas may also be formed by the acoustic black hole vibration reduction structure 320. The acoustic black hole vibration reduction structure 320 may be adjusted according to test data and the position may be selected to improve the overall noise reduction effect of the refrigerator.

[0101] In other embodiments, the inner wall of the guide cavity 311 is formed by the acoustic black hole vibration reduction structure 320. In this way, the effect of vibration reduction and noise reduction can be improved.

[0102] See also Figures 6 to 8 As shown, in some embodiments of the present application, the acoustic black hole vibration reduction structure 320 includes an acoustic black hole body 321 and a vibration reduction member 322 .

[0103] Among them, the acoustic black hole body 321 is connected to the guide member body 310, and the acoustic black hole body 321 includes a plurality of curved gradient segments that are smoothly transitioned and connected in sequence, and the curved gradient segment faces the inner wall surface of the guide cavity 311 to form the inner wall surface of the guide cavity 311.

[0104] It is understandable that the smooth transition connection of each curved gradient segment is conducive to the smooth inner wall surface of the guide cavity 311, thereby reducing the collision noise between the flip beam assembly 212 and the inner wall of the guide cavity 311. It should be noted that the more the number of curved gradient ends, the better, and this embodiment does not specifically limit the number of curved gradient ends.

[0105] Among them, along the length direction of the box, from the side close to the guide body 310 to the side away from the guide body 310, the projection area of ​​the curved gradient section toward the ground gradually decreases. Figure 3 In the direction indicated by the Z axis, the cross-sectional size of the curved gradient section along the direction parallel to the ground gradually decreases from the side close to the guide body 310 to the side away from the guide body 310.

[0106] It can be understood that the reliability of the connection between the curved gradient section and the guide member body 310 is improved by connecting the curved gradient section with the guide member body 310 at the end with a larger size.

[0107] The vibration damping member 322 is connected to a side of the curved gradient section away from the guide member body 310 .

[0108] When the flip beam assembly 212 moves in the guide cavity 311, the flip beam assembly 212 collides with the curve gradient section, and the curve gradient section vibrates. The vibration energy of the curve gradient section will be concentrated at the minimum cross-sectional dimension of the curve gradient section. The vibration damping member 322 is connected to the side of the curve gradient section away from the guide member body 310, so that it can receive the vibration energy concentrated at the minimum cross-sectional dimension of the curve gradient section. The vibration energy is converted into heat energy dissipation through the deformation of the vibration damping member 322, so that the structural loss factor is improved, the dissipated vibration energy is increased, and the vibration reduction effect is improved.

[0109] It should be noted that the smaller the minimum cross-sectional size, the better the vibration energy gathering effect.

[0110] In some embodiments, the vibration-damping member 322 may be a vibration-damping pad, and the material of the vibration-damping pad may be a vibration-damping material such as rubber or foam, which is not specifically limited in this embodiment.

[0111] In a possible implementation, the vibration damper 322 is embedded in one end of the curve gradient section away from the guide body 310. In this way, the flip beam assembly 212 collides with the curve gradient section, and the curve gradient section vibrates. The vibration energy of the curve gradient section is gathered at the minimum cross-sectional dimension of the curve gradient section and transferred to the vibration damper 322 located at the minimum cross-sectional dimension. The vibration energy is converted into heat energy dissipation through the deformation of the vibration damper 322.

[0112] In other embodiments, the vibration damper 322 is embedded in the side of the acoustic black hole body 321 away from the guide cavity 311, and the vibration damper 322 abuts against the side of the acoustic black hole body 321 away from the guide cavity 311. In this way, the flip beam assembly 212 collides with the curve gradient section, and the curve gradient section vibrates. The vibration energy of the curve gradient section is gathered at the minimum cross-sectional dimension of the curve gradient section and transmitted to the vibration damper 322 located on the side of the minimum cross-sectional dimension, and the vibration energy is converted into heat energy dissipation through the deformation of the vibration damper 322.

[0113] It is understandable that the vibration damping member 322 is embedded at the end of the curve gradient section away from the guide member body 310, the size of the acoustic black hole body 321 is small, and the flip beam assembly 212 is easy to collide and damage the acoustic black hole body 321. In this embodiment, the vibration damping member 322 is embedded at the side of the acoustic black hole body 321 away from the guide cavity 311, so as to improve the strength of the acoustic black hole body 321 and effectively avoid damage to the acoustic black hole body 321.

[0114] See also Fig. 9 and Fig.10As shown, in some embodiments of the present application, in order to improve the strength of the acoustic black hole body 321 , the length dimension of the vibration damping member 322 along the length direction of the box body 100 is not less than half of the length dimension of the acoustic black hole body 321 .

[0115] It should be noted that, along the length direction of the box body 100 , the larger the length dimension of the vibration damping member 322 is, the more conducive it is to improving the strength of the acoustic black hole body 321 .

[0116] Therefore, in some embodiments, along the length direction of the box 100 , the length dimension of the vibration damping member 322 is equal to the length dimension of the acoustic black hole body 321 .

[0117] See e.g. 9 and Fig.10 As shown, in some embodiments of the present application, the boundary curve formed by the projection of the surface of each curved gradient segment away from the vibration damping member 322 toward the corresponding first plane conforms to the following formula:

[0118] Y=aX b

[0119] Where b is not less than 2. a is not equal to 0

[0120] The plane perpendicular to the tangent line of the orthographic projection of the curve gradient segment toward the ground is the corresponding first plane.

[0121] The origin position is the end point of the boundary curve away from the guide body 310 .

[0122] Where X is the distance from the origin along the length of the box.

[0123] Wherein, Y is the distance from the origin along a direction perpendicular to the length direction of the box and parallel to the corresponding first plane.

[0124] For example, Y=3X 2

[0125] Or, Y = 5X 3

[0126] It should be noted that the coordinate direction corresponding to the boundary curve, such as Fig.10 shown.

[0127] It can be understood that, compared with acoustic black hole structures of other dimensions, the acoustic black hole body 321 in this embodiment is configured as a one-dimensional acoustic black hole beam structure, which has a relatively simple overall structure and is easy to implement.

[0128] See also Fig.11As shown, in some embodiments of the present application, in order to effectively prevent the vibration damper 322 from falling off the guide body 310, the vibration damper 322 includes a vibration damper body 3221 and a first limiting structure 3222 arranged on the side of the vibration damper body 3221 facing the guide body 310.

[0129] The guide member body 310 is provided with a second limiting structure matching the first limiting structure 3222 , and the first limiting structure 3222 is engaged with the second limiting structure.

[0130] Exemplarily, one of the first limiting structure 3222 and the second limiting structure is a limiting protrusion, and the other is a limiting cavity matching the limiting protrusion, and the limiting protrusion is snapped into the limiting cavity.

[0131] In this embodiment, in order to improve the strength of the vibration damping member 322, the first limiting structure 3222 is a limiting protrusion.

[0132] It should be noted that the vibration reduction body 3221 and the first limiting structure 3222 can be an integrated structure.

[0133] In some embodiments, the number of the first limiting structure 3222 and the second limiting structure can be multiple, and the multiple first limiting structures 3222 are arranged at intervals. The multiple second limiting structures are arranged in a one-to-one correspondence with the multiple first limiting structures 3222.
