[0002] At present, refrigerator noise is an important indicator of refrigerator performance. Compressor noise is the main noise source, and its noise contribution often accounts for more than 70%. In addition, refrigerator abnormal noise frequently occurs in the compressor compartment, which seriously affects the sound quality of refrigerator noise. Figure 1 As shown, in the prior art, a silencer is usually provided at the ventilation windows on the left and right sides of the compressor compartment 300, and the noise of the compressor compartment 300 is reduced by the silencer. A through hole 101 is provided on the side wall of the silencer, a silencer cavity is provided inside the silencer body, and a sound absorption hole connected to the silencer cavity is provided on the peripheral wall of the through hole. The through holes 101 of the two silencers are coaxially arranged, and each hole is both an air inlet and an air outlet, and the heat flow line is relatively chaotic. Therefore, the symmetrically arranged through holes have a poor heat dissipation effect on the compressor compartment, which is easy to cause overheating and shutdown and affect the service life of the compressor.

[0013] Optionally, the compressor comprises an upper shell and a lower shell, and a connection area is provided between the upper shell and the lower shell;

[0014] The central axis of the second through hole is located between the central position of the condenser in the height direction and the connection area.

[0021] The type of welding is vibration friction welding or ultrasonic welding.

[0022] In the present invention, on the one hand, since the through holes of the two silencers are asymmetrical structures; therefore, in the scenario of no heat dissipation fan in the compressor compartment and natural convection, when the compressor is working, based on the principle that the density of hot air is small and the density of cold air is large, and the hot air will automatically rise, the high-temperature airflow in the compressor compartment automatically flows upward and is discharged from the compressor compartment through the first through hole, and at the same time, a negative pressure is generated at the bottom of the compressor compartment. Under the action of the atmospheric pressure outside the compressor compartment, the outside air enters the compressor compartment through the second through hole. Compared with the symmetrical through holes of the two silencers, the asymmetrical through holes of the two silencers make the heat flow lines in the compressor compartment form a smooth air path even when there is no fan in the compressor compartment, thereby improving the heat dissipation efficiency of the compressor compartment and further improving the service life of the compressor. On the other hand, since the central axis of the first through hole is located between the top of the compressor and the top wall of the compartment wall, it not only provides an accurate reference for the design and manufacture of the first through hole, but also facilitates the manufacture and assembly of the silencer device on the outlet side of the compressor compartment, and is more conducive to the discharge of high-temperature gas from the compressor compartment.

[0042] Figure 2 Yes, the schematic structure diagram of the refrigeration and freezing device is as follows: Figure 2 As shown, and refer to Figures 2 to 13 An embodiment of the present invention provides a refrigeration and freezing device, which includes a silencer 100 and a compressor compartment 300.

[0043] like Figure 9-13 As shown, the silencer device 100 includes a silencer body, a through hole 101 penetrating the silencer body is opened on the side wall of the silencer body, at least one silencer cavity 103 is arranged inside the silencer body, at least one sound absorption hole 102 is opened on the peripheral wall 113 of the through hole 101, and each sound absorption hole 102 is connected to at least one silencer cavity 103.

[0044] like Figure 2 and Figure 3 As shown, a compressor 301 is provided in the compressor compartment 300, and the compressor compartment 300 includes a compartment wall, and silencers 100 are installed on the left and right walls of the compartment wall; the through holes 101 of the two silencers 100 are respectively a first through hole 1011 and a second through hole 1012, and the central axis of the first through hole 1011 is located between the top of the compressor and the top wall of the compartment wall, and the second through hole 1012 is lower than the first through hole 1011.

[0045] The working principle of the silencer 100 of the present invention is as follows: when in use, the silencer 100 is installed inside the refrigeration and freezing device to reduce the noise inside the compressor compartment 300. Specifically, the silencer 100 can be placed inside or outside the compressor compartment 300, and the through hole 101 connects the inside and outside of the compressor compartment 300. When the noise inside the compressor compartment 300 propagates from the inside to the outside, the noise passes through the silencer 100 inside or outside the compressor compartment 300, and the noise enters the inside of the silencer cavity 103 through the through hole 101 and the sound absorption hole 102. Under the silencing effect of the silencer cavity 103, the noise is significantly reduced. In addition, the through hole 101 of the silencer body also has the function of heat dissipation, which can transfer the heat in the compressor compartment 300 to the outside of the compressor.

[0046] Specifically, the warehouse wall includes a front wall, a rear wall, a top wall, a bottom wall, a left wall and a right wall. The silencer 100 is installed on the left and right sides of the compressor warehouse 300; after the silencer 100 is installed to reduce noise, the compressor warehouse 300 is basically in a closed state, and only the silencers 100 on the left and right walls of the warehouse wall of the compressor warehouse 300 are provided with through holes 101 that can be used for ventilation, and other positions are basically closed except for screw holes or reserved holes on the rear wall and bottom wall of the warehouse wall of the compressor warehouse 300; therefore, when the compressor warehouse 300 is basically closed and there is no heat dissipation fan in the compressor warehouse 300, the heat is mainly dissipated by natural convection through the through holes 101 of the silencer 100 on the left and right sides of the compressor warehouse 300.

[0047] In this embodiment, on the one hand, since the through holes 101 of the two silencers 100 are asymmetrical structures; therefore, Figure 4 As shown, in the scenario where there is no heat dissipation fan in the compressor compartment 300 and natural convection occurs, the scenario includes the case where only a compressor is provided in the compressor compartment 300. When the compressor is working, based on the principle that the density of hot air is small and the density of cold air is large, and hot air will automatically rise, the high-temperature airflow in the compressor compartment 300 automatically flows upward and is discharged from the compressor compartment 300 through the first through hole 1011, and at the same time, negative pressure is generated at the bottom of the compressor compartment 300. Under the action of the atmospheric pressure outside the compressor compartment 300, the outside air enters the compressor compartment 300 through the through hole 101 at the lower position. In other words, the first through hole 1011 at the upper position is the airflow outlet, and the second through hole 1012 at the lower position is the airflow inlet, thereby forming an airflow that runs through the compressor compartment 300, so that the airflow can quickly flow through the compressor compartment 300, take away the heat in the compressor compartment 300, and have a good heat dissipation effect.

[0048] In summary, compared with the symmetrical through holes 101 of the two silencers 100, the asymmetrical through holes 101 of the two silencers 100 can make the heat flow lines in the compressor compartment 300 form a smooth air path when there is no fan in the compressor compartment 300, thereby improving the heat dissipation efficiency of the compressor compartment 300 and further improving the service life of the compressor. On the other hand, since the central axis of the first through hole 1011 is located between the top of the compressor and the top wall of the compartment wall, it not only provides an accurate reference for the design and manufacture of the first through hole 1011, but also facilitates the manufacture and assembly of the silencer 100 on the air outlet side of the compressor compartment 300, and is more conducive to the discharge of high-temperature gas from the compressor compartment 300.

[0049] In summary, compared with the prior art, the present invention can not only effectively reduce the noise of the compressor compartment and improve the sound quality, but also effectively dissipate the heat of the compressor compartment and increase the service life of the compressor.

[0050] like Figure 3 As shown, in some embodiments of the present invention, the compressor 301 includes an upper shell 3011 and a lower shell 3012, and a connecting area 3013 is provided between the upper shell 3011 and the lower shell 3012; the central axis of the second through hole 1012 is located between the connecting area 3013 and the bottom wall of the bin wall.

[0051] In this embodiment, since the central axis of the second through hole 1012 is located between the connecting area 3013 and the bottom wall of the bin wall, on the one hand, there is a larger height difference between the first through hole 1011 and the second through hole 1012, which is more conducive to the entry of cold air into the compressor bin 300 and can extend the flow path of the airflow in the compressor bin 300, so that the compressor bin 300 has a better heat dissipation effect; on the other hand, it provides a more precise benchmark for the design and manufacture of the second through hole 1012, which is more convenient for the manufacture and assembly of the silencer 100 on the air inlet side of the compressor bin 300, and can improve the manufacturing accuracy and production efficiency.

[0052] Further, in some embodiments of the present invention, the connection area 3013 between the upper shell 3011 and the lower shell 3012 is a welding area, that is, the upper shell 3011 and the lower shell 3012 are welded together.

[0053] like Figure 3 As shown, in some embodiments of the present invention, the horizontal distance between the first through hole 1011 and the compressor is smaller than the horizontal distance between the second through hole 1012 and the compressor.

[0054] In this embodiment, since the compressor is located close to the first through hole 1011 (ie, the air flow outlet), it is more conducive to the high-temperature air flow to be quickly discharged from the compressor compartment 300, thereby further improving the heat dissipation effect.

[0055] In some alternative embodiments of the present invention, the horizontal distance between the first through hole 1011 and the compressor is equal to the horizontal distance between the second through hole 1012 and the compressor. In other words, the compressor is located in the middle of the compressor compartment 300, and its distance from both sides of the compressor compartment 300 is equal.

[0056] like Figure 5-6 As shown, in some embodiments of the present invention, a heat dissipation fan 302 is also provided in the compressor compartment 300, and the heat dissipation fan 302 is used to blow the wind on the air inlet side of the compressor compartment 300 to the air outlet side of the compressor compartment 300, and the compressor is located on the air outlet side of the compressor compartment 300.

[0057] Specifically, the first through hole 1011 is located at the air outlet side of the compressor compartment 300, and the second through hole 1012 is located at the air inlet side of the compressor compartment 300. When in use, the heat dissipation fan 302 can blow the air on the air inlet side of the compressor to the first through hole 1011 located at the air outlet side of the compressor compartment 300 through the second through hole 1012, so that the airflow in the compressor compartment 300 flows out quickly from the side close to the compressor.

[0058] In this embodiment, the compressor is located at the air outlet side of the compressor compartment 300. Under the action of the heat dissipation fan 302, air with a lower temperature than the compressor can be inhaled, and the air flow speed in the compressor compartment 300 can be accelerated, so that the heat in the compressor compartment 300 can be quickly discharged. Therefore, compared with the solution of only arranging the compressor in the compressor compartment, by arranging the heat dissipation fan in the compressor compartment, the heat dissipation efficiency of the compressor compartment can be further improved, so that it has a better heat dissipation effect.

[0059] like Figure 7 As shown, in other embodiments of the present invention, the refrigerating and freezing device further includes a condenser 303, which is disposed in the compressor compartment 300, and the condenser 303 is located on the air inlet side of the compressor compartment 300, and the heat dissipation fan 302 is located between the compressor compartment 300 and the condenser 303. In this embodiment, the air enters the compressor compartment 300 from the side of the condenser 303, and the heat dissipation fan 302 can dissipate heat for the compressor and the condenser 303 at the same time. In other words, the compressor and the condenser 303 share a heat dissipation fan 302, thereby increasing the storage space of the refrigerating and freezing device.

[0060] like Figure 8As shown, in some alternative embodiments, the refrigerator and freezer further comprises a condenser 303, the condenser 303 is arranged in the compressor compartment 300, the heat dissipation fan 302 is located at the air inlet side of the compressor compartment 300, and the condenser 303 is located between the compressor compartment 300 and the heat dissipation fan 302. In this embodiment, the heat dissipation fan 302 can dissipate heat for the compressor and the condenser 303 at the same time, that is, the compressor and the condenser 303 share a heat dissipation fan 302, thereby increasing the storage space of the refrigerator and freezer.

[0061] Further, in some embodiments of the present invention, Figure 6 As shown, the compressor includes an upper shell 3011 and a lower shell 3012, and a connection area 3013 is provided between the upper shell 3011 and the lower shell 3012. The central axis of the second through hole 1012 is located between the center position of the condenser 303 in the height direction and the connection area 3013.

[0062] Specifically, the central axis of the second through hole 1012 of the compressor compartment 300 is located between the center position of the condenser 303 in the height direction and the center position of the compressor in the height direction.

[0063] In this embodiment, on the one hand, the height center of the second through hole 1012 (air inlet) is set in an interval range, which can maximize the intake of air with a temperature lower than the compressor temperature, so that there is a large height difference between the first through hole 1011 and the second through hole 1012, which is more conducive to the cold air entering the compressor compartment 300, and can extend the flow path of the airflow in the compressor compartment 300, so that the compressor compartment 300 has a better heat dissipation effect. On the other hand, it provides a more accurate reference for the design and manufacture of the second through hole 1012, which is more convenient for the manufacture and assembly of the silencer 100 on the air inlet side of the compressor compartment 300, and can improve the manufacturing accuracy and production efficiency.

[0064] In other embodiments of the present invention, Figure 7 As shown, the central axis of the second through hole 1012 is located between the center position of the condenser 303 in the height direction and the bottom wall of the warehouse wall.

[0065] In this embodiment, since the central axis of the second through hole 1012 is located between the center position of the condenser 303 in the height direction and the bottom wall of the warehouse wall, on the one hand, there is a larger height difference between the first through hole 1011 and the second through hole 1012, which is more conducive to the entry of cold air into the compressor warehouse 300, and can extend the flow path of the airflow in the compressor warehouse 300, so that the compressor warehouse 300 has a better heat dissipation effect; on the other hand, it provides a more precise benchmark for the design and manufacture of the second through hole 1012, which is more convenient for the manufacture and assembly of the silencer 100 on the air inlet side of the compressor warehouse 300, and can improve the manufacturing accuracy and production efficiency.

[0066] like Figure 9-13 As shown, in some embodiments of the present invention, at least one muffler cavity 103 is provided inside the muffler body, at least one sound absorbing hole 102 is provided on the peripheral wall 113 of the through hole 101, and each sound absorbing hole 102 is connected to at least one muffler cavity 103. The muffler body is a split structure, and the muffler body is divided into a first body 110 and a second body 120 along its thickness direction, and the muffler cavity 103 is enclosed by the first body 110 and the second body 120.

[0067] During the manufacturing process, the first body 110 and the second body 120 are manufactured separately; after the first body 110 and the second body 120 are manufactured respectively, the first body 110 and the second body 120 are assembled together to form the silencer 100. During the separate manufacturing process, it is convenient to design a plurality of silencer cavities 103 of different lengths, widths and heights according to the noise reduction requirements, so that the silencer cavities 103 of different sizes correspond to different noise reduction pressure bands, so that the silencer 100 can have a better noise reduction effect.

[0068] In this embodiment, since the muffler body is a split structure, the production and preparation of the first body 110 and the second body 120 are convenient, and the difficulty of production and processing is reduced. Therefore, the muffler body of the present invention is convenient to manufacture and assemble, thereby simplifying the manufacturing process of the refrigeration and freezing device and saving production costs; in addition, it is convenient to set a plurality of muffler cavities 103 of different sizes inside the muffler body, which is more conducive to absorbing noises of different frequencies.

[0069] like Fig.10 and Fig.11 As shown, in some embodiments of the present invention, the first body 110 includes a first side panel 111, a peripheral wall 113 and a muffler chamber partition 112 located on the first side panel 111; the second body 120 includes a second side panel 121 and a slot 122 located on the second side panel 121 and plugged into the muffler chamber partition 112. The first side panel 111, the muffler chamber partition 112, the peripheral wall 113 and the second side panel 121 together enclose a through hole 101 and a muffler chamber 103.

[0070] During the manufacturing and assembly process, the first body 110 and the second body 120 are first manufactured separately, and then the two are assembled together. Specifically, the muffler cavity partition 112 of the first body 110 is inserted into the slot 122 of the second body 120, and the peripheral wall 113 of the first body 110 is in contact with the second side plate 121 of the second body 120, so that the first body 110 and the second body 120 are enclosed together to form the through hole 101 and the muffler cavity 103.

[0071] In this embodiment, since the silencer cavity partition 112 is inserted into the slot 122, on the one hand, each silencer cavity 103 can be a closed cavity, thereby improving the sealing effect and noise reduction effect of each silencer cavity 103; on the other hand, it can also play a positioning role, thereby improving the assembly efficiency of the first body 110 and the second body 120.

[0072] like Fig.13 As shown, further, in some embodiments of the present invention, the muffler cavity partition 112 is perpendicular to the first side plate 111 to facilitate production.

[0073] Furthermore, the peripheral wall 113 is perpendicular to the first side plate 111 , so that the silencer 100 has a beautiful appearance and is easy to manufacture.

[0074] like Fig.11 As shown, in some embodiments of the present invention, a convex strip 123 forming a slot 122 is disposed on the second side plate 121. In some alternative embodiments of the present invention, a concave portion forming the slot 122 is provided on the surface of the first side wall.

[0075] In this embodiment, since the slot 122 is composed of spaced convex strips 123, the depth of the slot 122 can be increased, thereby increasing the size of the portion of the muffler cavity partition 112 inserted into the slot 122, thereby further improving the sealing effect and noise reduction effect of each muffler cavity 103.

[0076] like Fig.13 As shown, in some embodiments of the present invention, there is a gap between the two side walls of the slot 122 and the corresponding muffler cavity partition 112 .

[0077] In this embodiment, since the slot 122 and the muffler cavity partition 112 are clearance-matched, the slot 122 can be easily inserted into place, and the sealing of the muffler cavity 103 can be further improved, so that it has a better noise reduction effect.

[0078] In some embodiments of the present invention, an edge of the peripheral wall 113 away from the first side plate 111 is welded to the second side plate 121 .

[0079] During the manufacturing and assembly process, the muffler cavity partition 112 of the first body 110 is inserted into the slot 122 of the second body 120, and the peripheral wall 113 of the first body 110 is in contact with the second side plate 121 of the second body 120, and then the connection position between the peripheral wall 113 and the second side plate 121 is welded to fix the two together.

[0080] In this embodiment, the welding method can improve the sealing performance of the silencer 100 compared with the fastening connection or the clamping method, so that the silencer 100 can have a better noise reduction effect.

[0081] Furthermore, in some embodiments of the present invention, the type of welding is vibration friction welding.

[0082] Specifically, the edge of the peripheral wall 113 away from the first side plate 111 is fixedly connected to the second side plate 121 by means of vibration friction welding. Vibration friction welding is a technology that uses the heat generated by interface friction caused by the relative vibration of two welds to achieve welding. The welds are placed on a specified device and vibrate and rub on the contact surface under a certain pressure until the interface begins to melt. Then the vibration is stopped and the pressure is maintained until solidification, thereby achieving the welding purpose. By using the vibration friction welding method, the connection strength between the peripheral wall 113 and the second side plate 121 can be improved, and the welding speed can also be increased. In addition, no welding smoke and pollutants such as manganese and nickel that are harmful to the human body are generated during the welding process.

[0083] In other embodiments of the present invention, the type of welding is ultrasonic welding.

[0084] Specifically, the edge of the peripheral wall 113 away from the first side plate 111 is fixedly connected to the second side plate 121 by ultrasonic welding. Compared with the traditional welding method, ultrasonic welding has significant advantages, such as fast welding speed, high welding efficiency, good weld quality, beautiful weld, clean and environmentally friendly welding process, and is very suitable for mass production. Therefore, ultrasonic welding is a fast, clean and effective assembly process.

[0085] In some embodiments of the present invention, the outer contour of the second side plate 121 is larger than the outer contour of the peripheral wall 113 so that the weld or the solder does not extend beyond the second body 120 after welding.

[0086] In this embodiment, since the outer contour of the second side plate 121 is larger than the outer contour of the peripheral wall 113, after welding, the weld or solder between the two will not be at the outermost edge of the silencer 100, thereby making the appearance of the silencer 100 more beautiful.

[0087] In some alternative embodiments of the present invention, the outer contour of the second side plate 121 is equal to the outer contour of the peripheral wall 113 .

[0088] In some alternative embodiments of the present invention, the fixed connection between the peripheral wall 113 and the second side plate 121 is a fastening connection. For example, connection holes are provided on the edges of the second side plate 121 and the peripheral wall 113 away from the first side plate 111; the muffler cavity partition 112 of the first body 110 is inserted into the slot 122 of the second body 120, and the peripheral wall 113 of the first body 110 is in contact with the second side plate 121 of the second body 120, and then screws are inserted into the connection holes, and the first body 110 and the second body 120 are fastened together by the screws. This fastening connection method has the advantages of easy operation and high assembly efficiency.

[0089] In some other alternative embodiments of the present invention, the fixed connection between the peripheral wall 113 and the second side plate 121 is achieved by snap-fitting.

[0090] In some optional embodiments of the present invention, at least one muffler cavity 103 has a labyrinth structure.

[0091] In this embodiment, compared with the sound-flow structure, honeycomb structure or straight tube structure of the silencer cavity 103, the labyrinth structure of the silencer cavity 103 is deeper, which can significantly extend the sound propagation path and constitute an acoustic superstructure, thereby further enhancing the noise reduction effect of the silencer device 100.

[0092] In some other optional embodiments of the present invention, at least one muffler cavity 103 is in an acoustic flow structure.

[0093] In some other optional embodiments of the present invention, at least one muffler cavity 103 has a honeycomb structure.

[0094] In some other optional embodiments of the present invention, at least one muffler chamber 103 is a straight tube structure.

[0095] In some optional embodiments of the present invention, the sound-absorbing body is a sound-absorbing metamaterial.

[0096] Specifically, the sound-absorbing metamaterial (MAT metamaterial, MAT is the abbreviation of Metamaterial Absorption Technology) uses a synthetic material with high sound absorption efficiency, and there is a complex maze pattern structure on it. Each maze channel can absorb specific frequencies, and its sound absorption efficiency is as high as 99%. In addition, compared with general sound-absorbing materials, the chemical properties of sound-absorbing metamaterials are more stable, safer, odorless, elastic, fire-retardant, mildew-proof and anti-bacterial, and have a good feel and weight.

[0097] In some alternative embodiments of the present invention, the silencer body is made of ABS material.

[0098] In some embodiments of the present invention, the diameter of the through hole 101 is 10-200 mm.

[0099] For example, the diameter of the through hole 101 is 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 80 mm, 100 mm, 120 mm, 150 mm, 180 mm or 200 mm.

[0100] Specifically, since the through hole 101 on the muffler body can be used as both a sound inlet and a heat dissipation hole, a large aperture of the through hole 101 is beneficial to heat dissipation, but a large aperture will result in a decrease in noise reduction; a small aperture of the through hole 101 is beneficial to noise reduction, but the heat dissipation will decrease. Therefore, in this embodiment, by setting the aperture of the through hole 101 to a reasonable size, the muffler device 100 can have both a good noise reduction effect and a good heat dissipation effect.

[0101] like Fig. 9 As shown, in some optional embodiments of the present invention, a mounting and assembly interface 130 for mounting a ventilation grille is provided at the through hole 101. In this embodiment, the mounting and assembly interface 130 is a snap-on structure, and the mounting and assembly interface 130 is consistent with the existing interface, and is used to mount the ventilation grille, thereby improving versatility and practicality, and reducing costs, and can be used for refrigeration and freezing devices of different categories and models.

[0103] In this embodiment, by installing the silencer 100 inside the refrigeration device, the noise inside the refrigeration device can be reduced, thereby improving the user experience.

[0104] In some optional embodiments of the present invention, the silencer 100 is installed on the inner side of the warehouse wall of the compressor warehouse 300. A through hole corresponding to the through hole 101 is opened on the corresponding warehouse wall.

[0105] When in use, when the noise in the compressor compartment 300 propagates from the inside to the outside, it passes through the muffler body, and under the obstruction of the side wall of the muffler body, the noise enters the muffler cavity 103 through the through hole 101 and the sound absorption hole 102, thereby extending the propagation path of the sound. Under the muffler effect of the muffler cavity 103, the noise is significantly reduced. The heat in the compressor is transported to the outside of the compressor compartment 300 through the through hole 101 and the through hole.

[0106] In some other optional embodiments of the present invention, the silencer 100 is installed on the outer side of the compartment wall of the compressor compartment 300 , and a through hole corresponding to the through hole 101 is opened on the corresponding compartment wall.

[0107] When in use, when the noise in the compressor compartment 300 propagates from the inside to the outside, it passes through the muffler body, and under the obstruction of the side wall of the muffler body, the noise enters the muffler cavity 103 through the through hole, the through hole 101 and the sound absorption hole 102. Under the muffler effect of the muffler cavity 103, the noise is significantly reduced. The heat in the compressor is transported to the outside of the compressor compartment 300 through the through hole and the through hole 101. In addition, the muffler device 100 is installed in the foam layer around the compressor compartment 300, which does not occupy the volume of the refrigerator extra, that is, the volume of the refrigerator can be lost as little as possible, and the installation is stable and firm, impact-resistant, and meets the transportation test.

[0108] In some optional embodiments of the present invention, a through hole for installing a silencer is provided on the warehouse wall. Specifically, the silencer is installed in the through hole.

[0109] In some embodiments of the present invention, the refrigerator and freezer further comprises a ventilation grille, which is installed at one end of the through hole 101 away from the compressor compartment 300. Further, the ventilation grille is located outside the compressor compartment 300.

[0110] In order to facilitate the installation of the ventilation grille and meet the universal requirements, the ventilation grille is installed on the end of the through hole 101 away from the compressor compartment 300 through a snap-on structure. The snap-on structure includes a snap-on hole strip, a snap-on protrusion and a snap buckle. The two ends of the snap-on hole strip are connected to the hole edge of the through hole 101 away from the compressor compartment 300 to define the snap-on hole. The snap-on protrusion is arranged in the snap-on hole and connected to the hole edge of the through hole 101 away from the compressor compartment 300. The snap buckle is connected to the surface of the ventilation grille facing the compressor compartment 300, inserted into the snap-on hole, and matched with the snap-on protrusion.

[0111] In some optional embodiments of the present invention, the refrigerating and freezing device is a refrigerator.
