[0051] Figure 1 FIG. 1 is a schematic rear view of a refrigerator-freezer according to an embodiment of the present invention. Figure 1 As shown, and refer to Figures 2 to 6 The embodiment of the utility model provides a compressor chamber including a chamber body 100, a closing plate 700 and a magnetic device 800. The chamber body 100 defines an installation space 110 having an opening for installing a compressor 500. The closing plate 700 covers the opening 111 of the installation space 110. And the magnetic device 800 is configured to allow the closing plate 700 to be installed on the chamber body 100 by magnetic attraction.

[0052] In this embodiment, the closing plate 700 is connected to the warehouse body 100 through the magnetic device 800 to cover the opening 111 of the installation space 110. The magnetic device 800 makes it difficult for the connection between the closing plate 700 and the warehouse body 100 to be loosened, avoiding the gap between the closing plate 700 and the warehouse body 100 at the opening 111 of the installation space 110, and thus the closing plate 700 and the warehouse body 100 will not collide when the compressor 500 is working, avoiding the noise caused by the collision between the closing plate 700 and the warehouse body 100, thereby improving the user experience. Moreover, compared with the closing plate 700 being connected to the warehouse body 100 by threads, the closing plate 700 is connected to the warehouse body 100 by the magnetic device 800, which also avoids the phenomenon of screws or studs slipping when the refrigeration and freezing device is repaired, resulting in a gap between the closing plate 700 and the warehouse body 100, or even causing the closing plate 700 to be unable to be installed in the warehouse body 100, thereby making the design of the compressor warehouse improve the user experience.

[0053] In some embodiments of the press chamber of the present utility model, as Figure 2 As shown, the hopper body 100 has an annular contact surface 120 facing the closing plate 700 , and any portion on the annular contact surface 120 contacts a corresponding portion on the circumferential edge of the closing plate 700 .

[0054] In this embodiment, the closing plate 700 is connected to the annular contact surface 120 of the warehouse body 100 through the circumferential edge of the closing plate 700, so as to increase the contact area between the closing plate 700 and the warehouse body 100, thereby improving the stability of the connection between the closing plate 700 and the warehouse body 100. Moreover, the annular contact surface 120 is in contact with the corresponding part of the circumferential edge of the closing plate 700, thereby avoiding the existence of a gap between the warehouse body 100 and the closing plate 700, thereby reducing the noise generated by the collision between the closing plate 700 and the warehouse body 100.

[0055] In some embodiments of the press chamber of the present utility model, as Figure 4 As shown, the magnetic attraction device 800 includes a first magnetic member 810 .

[0056] The first magnetic member 810 is in a ring shape surrounding the circumferential edge of the closing plate 700 , and the first magnetic member 810 is disposed at the circumferential edge of the closing plate 700 .

[0057] In this embodiment, the first magnetic member 810 is provided on the closing plate 700, and the first magnetic member 810 is located at the circumferential edge of the closing plate 700, and the annular contact surface 120 of the warehouse body 100 is a ferromagnetic material, and the closing plate 700 is connected to the warehouse body 100 through the connection between the first magnetic member 810 and the annular contact surface 120. When it is necessary to cover the opening 111 of the installation space 110, the side of the closing plate 700 provided with the first magnetic member 810 is directed toward the opening 111 of the installation space 110, and the closing plate 700 covers the opening 111 of the installation space 110, so that the first magnetic member 810 is magnetically connected to the annular contact surface 120, so as to fix the closing plate 700. When it is necessary to expose the opening 111 of the installation space 110, the closing plate 700 can be removed from the warehouse body 100. The design of the compressor chamber makes it difficult for the connection between the closing plate 700 and the chamber body 100 to become loose, avoiding the gap between the closing plate 700 and the chamber body 100 at the opening 111 of the installation space 110, and thus the closing plate 700 and the chamber body 100 will not collide when the compressor 500 is working, avoiding the noise caused by the collision between the closing plate 700 and the chamber body 100, thereby improving the user experience. Moreover, compared with the closing plate 700 being connected to the chamber body 100 by threads, the closing plate 700 is connected to the chamber body 100 by a magnetic device 800, which also avoids the phenomenon of screws or studs being stripped when the refrigeration and freezing device is repaired, resulting in a gap between the closing plate 700 and the chamber body 100, or even causing the closing plate 700 to be unable to be installed in the chamber body 100, thereby improving the user experience.

[0058] Alternatively, the first magnetic member 810 may also be disposed on the annular contact surface 120 of the chamber body 100, and the circumferential edge of the closing plate 700 in contact with the annular contact surface 120 may be made of ferromagnetic material.

[0059] Preferably, the first magnetic component 810 is made of neodymium iron boron permanent magnet material.

[0060] In some embodiments of the press chamber of the present utility model, as Figure 3 As shown, the magnetic attraction device 800 includes a second magnetic member 820. The second magnetic member 820 is in a ring shape surrounding the circumferential edge of the opening 111 of the installation space 110, and the second magnetic member 820 is arranged at the circumferential edge of the opening 111 of the installation space 110. The first magnetic member 810 is arranged radially outside the second magnetic member 820.

[0061] In this embodiment, the second magnetic member 820 is provided on the closing plate 700, and the second magnetic member 820 is located at the circumferential edge of the opening 111 of the installation space 110, and the annular contact surface 120 of the warehouse body 100 is a ferromagnetic material. The closing plate 700 is connected to the warehouse body 100 through the connection between the first magnetic member 810 and the second magnetic member 820 and the annular contact surface 120. Compared with the closing plate 700 being connected to the annular contact surface 120 only through the first magnetic member 810 or the second magnetic member 820, the closing plate 700 is connected to the annular contact surface 120 through the first magnetic member 810 and the second magnetic member 820 at the same time, so that the connection between the closing plate 700 and the annular contact surface 120 is more stable, further reducing the loosening of the connection between the closing plate 700 and the warehouse body 100, and avoiding the noise generated by the collision between the closing plate 700 and the warehouse body 100.

[0062] Alternatively, the second magnetic member 820 may also be disposed on the annular contact surface 120 of the chamber body 100, and the circumferential edge of the closing plate 700 in contact with the annular contact surface 120 may be made of ferromagnetic material.

[0063] Preferably, the second magnetic component 820 is made of neodymium iron boron permanent magnet material.

[0064] In some embodiments of the press chamber of the present utility model, as Figure 3 and Figure 4 As shown, the magnetic attraction device 800 includes a first magnetic member 810 . A first annular groove 610 is provided at the circumferential edge of the inner surface of the closing plate 700 , and the first magnetic member 810 is disposed in the first annular groove 610 .

[0065] The magnetic attraction device 800 includes a second magnetic member 820. A second annular groove 620 with an opening facing outward is provided on the chamber body 100, and the second annular groove 620 is located radially outside the opening 111 of the installation space 110, and the second magnetic member 820 is disposed in the second annular groove 620. The inner surface of the closing plate 700 is a side of the closing plate 700 close to the opening 111 of the installation space 110.

[0066] In this embodiment, the first magnetic member 810 is disposed on the closing plate 700, and the second magnetic member 820 can also be disposed on the annular contact surface 120 of the warehouse body 100, and the first magnetic member 810 is disposed in the first annular groove 610, and the second magnetic member 820 is disposed in the second annular groove 620, which reduces the distance between the closing plate 700 and the annular contact surface 120, and further reduces the noise generated by the collision between the closing plate 700 and the warehouse body 100. In addition, by reducing the distance between the closing plate 700 and the annular contact surface 120, when the outer surface of the closing plate 700 is flush with the warehouse body 100, the thickness of the closing plate 700 is increased to improve the strength of the closing plate 700, thereby improving the service life of the closing plate 700.

[0067] Furthermore, the surface of the first magnetic member 810 facing the storage body 100 is flush with the inner surface of the closing plate 700 . The surface of the second magnetic member 820 facing the closing plate 700 is flush with the rear surface of the storage body 100 .

[0068] Alternatively, the surface of the first magnetic member 810 facing the storage body 100 is higher than the inner surface of the closing plate 700 . The surface of the second magnetic member 820 facing the closing plate 700 is higher than the rear surface of the storage body 100 .

[0069] In some embodiments of the press chamber of the present invention, the first magnetic member 810 includes a plurality of third magnetic members which are sequentially spaced apart along the circumferential edge of the inner surface of the closing plate 700 .

[0070] In this embodiment, a plurality of third magnetic members arranged in sequence and at intervals reduces the usage of the third magnetic member material and reduces the cost of the press chamber.

[0071] Alternatively, the first magnetic member 810 is in a ring shape surrounding the circumferential edge of the closing plate 700 .

[0072] In this embodiment, the annular first magnetic member 810 improves the connection strength between the closing plate 700 and the annular contact surface 120 of the warehouse body 100 , and improves the stability of the closing plate 700 after being installed on the annular contact surface 120 of the warehouse body 100 .

[0073] In some embodiments of the press chamber of the present invention, the second magnetic member 820 includes a plurality of fourth magnetic members, which are sequentially spaced apart along the circumferential edge of the opening 111 of the installation space 110 .

[0074] Alternatively, the second magnetic member 820 is in a ring shape surrounding the circumferential edge of the opening 111 of the installation space 110 .

[0075] In some embodiments of the press chamber of the present utility model, as Figure 2 As shown, the opening 111 of the installation space 110 is a maintenance port on the rear side of the warehouse body 100, and the closing plate 700 is a rear cover plate of the maintenance port.

[0076] Alternatively, the opening 111 of the installation space 110 is downwardly facing the installation opening at the bottom of the warehouse body 100 , and the closing plate 700 is a support plate for installing the compressor 500 at the bottom of the warehouse body 100 .

[0077] In some embodiments of the press chamber of the present utility model, as Figure 4As shown, when the opening 111 of the installation space 110 faces backward, the closing plate 700 is a rear cover. The closing plate 700 is provided with a plurality of strip-shaped heat dissipation holes 710, each of which extends in a vertical direction. The plurality of strip-shaped heat dissipation holes 710 are provided at positions on the closing plate 700 corresponding to the compressor 500.

[0078] In this embodiment, the interior of the compressor compartment is connected to the outside through a plurality of strip-shaped heat dissipation holes 710 on the closing plate 700, so that the heat in the compressor compartment is discharged outward from the plurality of strip-shaped heat dissipation holes 710, and the plurality of strip-shaped heat dissipation holes 710 are arranged close to the compressor 500, so that the heat generated by the operation of the compressor 500 is effectively discharged from the compressor compartment, thereby improving the heat dissipation effect in the compressor compartment.

[0079] In some embodiments of the press chamber of the present utility model, as Figure 3 and Figure 5 As shown, the press chamber also includes a silencer 400 .

[0080] The bin body 100 has a first side wall 200 and a second side wall 300 which are arranged opposite to each other and are used to define the installation space 110. The first side wall 200 includes a first foaming layer 230. The first side wall 200 is provided with a first through hole 210 penetrating therethrough.

[0081] The noise reduction device 400 has a second through hole 410 therethrough.

[0082] The thickness H of the silencer 400 is greater than or equal to the thickness h1 of the first foaming layer 230 . The silencer 400 is disposed on the inner side surface of the first side wall 200 , and the first through holes 210 are aligned with the corresponding second through holes 410 .

[0083] Since the thickness H of the silencer 400 is greater than or equal to the thickness h1 of the first foaming layer 230, the silencer 400 cannot be installed in the first foaming layer 230, or it cannot be ensured that both sides of the silencer 400 after installation can be filled with foaming material to fix the silencer 400. The silencer 400 is arranged on the first side wall 200 and is located in the installation space 110, so that the silencer 400 is not limited by the thickness h1 of the first foaming layer 230, that is, without changing the thickness H of the silencer 400, the noise generated by the compressor 500 is effectively consumed. The silencer 400 is installed on the first side wall 200 and is located in the installation space 110, which reduces the noise generated outward from the compressor compartment, avoids the user from still being subjected to large noise, and improves the user experience.

[0084] Moreover, compared with setting the silencer 400 in the first side wall 200, the silencer 400 is located in the installation space 110, which is closer to the sound source generated by the compressor 500, so that the noise reduction effect of the silencer 400 is better. Furthermore, the silencer 400 can be installed in the installation space 110 after the foaming process of the first foaming layer 230 is completed, and there is no need to consider the installation of the silencer 400 during the filling of the foaming material, which simplifies the disassembly and assembly process of the silencer 400, and is also convenient for solving after-sales problems caused by damage to the silencer 400, thereby improving the user experience.

[0085] Alternatively, the silencer 400 may also be disposed on the outer surface of the first side wall 200 .

[0086] In this embodiment, the silencer 400 is installed on the outer side of the first side wall 200, and has a noise reduction effect on the external environment or the external noise of the refrigeration and freezing device. In addition, the silencer 400 is close to the user, thereby improving the noise reduction effect. Furthermore, compared with setting the silencer 400 inside the first side wall 200, the silencer 400 of this embodiment is farther away from the compressor 500, which reduces the influence of the heat generated by the compressor 500 on the silencer 400 and improves the service life of the silencer 400.

[0087] In some embodiments of the press chamber of the present utility model, as Figure 3 and Figure 5 As shown, the second side wall 300 further includes a second foaming layer 330. The second side wall 300 is provided with a third through hole 310 penetrating therethrough.

[0088] The thickness H of the silencer 400 is greater than or equal to the thickness h2 of the second foaming layer 330 . The silencer 400 is disposed on the inner side surface of the second side wall 300 , and the third through holes 310 are aligned with the corresponding second through holes 410 .

[0089] In this embodiment, the third through hole 310 and the first through hole 210 allow the airflow in the installation space 110 to flow in from one side and out from the other side, so that the airflow in the compressor chamber can flow quickly, thereby improving the heat dissipation effect in the compressor chamber.

[0090] Alternatively, the silencer 400 may also be disposed on the outer surface of the second side wall 300 .

[0091] In some alternative embodiments of the press chamber of the present invention, silencers 400 are provided on the inner and outer surfaces of the first side wall 200, and silencers 400 are provided on the inner and outer surfaces of the second side wall 300 to improve the noise reduction effect of the press chamber.

[0092] In some embodiments of the press chamber of the present utility model, as Figure 3 and Figure 5 As shown, the muffler 400 is in the installation space 110, and the surface of the muffler 400 facing the first side wall 200 contacts and abuts against the inner surface of the first side wall 200. The area ratio between the projection of the muffler 400 on the inner surface of the first side wall 200 and the inner surface of the first side wall 200 is 3 / 4 to 1.

[0093] In this embodiment, increasing the ratio of the projection area of ​​the silencer 400 on the inner surface of the first side wall 200 to the inner surface area of ​​the first side wall 200 is beneficial to improving the silencer effect of the silencer 400, thereby making the press chamber have a better noise reduction effect.

[0094] In some embodiments of the press chamber of the present utility model, as Figure 6 As shown, the silencer 400 has one or more silencer cavities 430 therein, and at least one sound absorption opening 420 is opened on the peripheral wall of the second through hole 410 , and each sound absorption opening 420 is connected to at least one silencer cavity 430 .

[0095] Furthermore, the silencing device 400 is made of metamaterial, the silencing cavity 430 is bent and extended, and the silencing cavity 430 is arranged radially outside the second through hole 410. A plurality of sound absorbing openings 420 are distributed at intervals along the circumference of the second through hole 410.

[0096] In this embodiment, the metamaterial may be a sound-absorbing metamaterial or a porous material to absorb noise. When the noise passes through the second through hole 410 , the sound-absorbing openings 420 spaced apart circumferentially of the second through hole 410 enter the silencing cavity, so that the noise is effectively consumed after passing through the silencing cavity 430 .

[0097] In some embodiments of the press chamber of the present utility model, as Figure 6 As shown, the plurality of sound absorbing openings 420 include a first sound absorbing opening 421 located below the axis of the second through hole 410 and a second sound absorbing opening 422 located above the axis of the second through hole 410. The area of ​​the first sound absorbing opening 421 is larger than that of the second sound absorbing opening 422.

[0098] In this embodiment, on the one hand, since the first sound absorption opening 421 is mainly used to reduce the noise of high-frequency sound waves, and the second sound absorption opening 422 is mainly used to reduce the noise of low-frequency sound waves, the area of ​​the second sound absorption opening 422 is smaller than that of the first sound absorption opening 421, which is more conducive to improving the noise reduction effect of the second sound absorption opening 422 on low-frequency sound waves, and more conducive to improving the noise reduction effect of the first sound absorption opening 421 on high-frequency sound waves, thereby improving the noise reduction effect of the compressor compartment, thereby reducing the noise emitted by the refrigeration and freezing device, so as to further improve the user experience. On the other hand, since the area of ​​the second sound absorption opening 422 is smaller than that of the first sound absorption opening 421, it is more conducive to dust removal and cleaning of the first sound absorption opening 421 with the opening facing upward and the muffler cavity 430 connected to the first sound absorption opening 421.

[0099] In some embodiments of the press chamber of the present utility model, as Figure 6 As shown, the depth of the muffler cavity 430 connected to the first sound absorbing opening 421 is smaller than the depth of the muffler cavity 430 connected to the second sound absorbing opening 422 .

[0100] In this embodiment, on the one hand, since the muffler cavity 430 includes the muffler cavity 430 connected to the second sound absorption opening 422 and the muffler cavity 430 connected to the first sound absorption opening 421, the depth of the muffler cavity 430 connected to the second sound absorption opening 422 is greater than the depth of the muffler cavity 430 connected to the first sound absorption opening 421. Therefore, based on the mechanism that the wavelength of low-frequency sound waves is longer than the wavelength of high-frequency sound waves, the muffler cavity 430 connected to the second sound absorption opening 422 is mainly used to reduce the noise of low-frequency sound waves, and the muffler cavity 430 connected to the first sound absorption opening 421 is mainly used to reduce the noise of high-frequency sound waves. In other words, the muffler device 400 can be used for both low-frequency noise reduction and high-frequency noise reduction. The muffler device 400 has a wide action band, a wide-band noise reduction effect and a good noise reduction effect, so that the compressor compartment can be effectively noise-reduced, the noise reduction effect of the refrigeration and freezing device is ensured, and the user experience is improved.

[0101] On the other hand, since the opening of the second sound absorption opening 422 connected to the muffler cavity 430 connected to the second sound absorption opening 422 faces downward, and the opening of the first sound absorption opening 421 connected to the muffler cavity 430 connected to the first sound absorption opening 421 faces upward. When in use, dust is not easy to enter the muffler cavity 430 connected to the second sound absorption opening 422, and the dust has little effect on the muffler cavity 430 connected to the second sound absorption opening 422. In addition, since the main frequency generated by the press chamber is low-frequency noise, even if dust enters the muffler cavity 430 connected to the first sound absorption opening 421, it will not have a significant impact on the noise reduction of the press chamber. Therefore, this design reduces the impact of dust on the noise reduction effect of the press chamber. In addition, since the depth of the muffler cavity 430 connected to the first sound absorption opening 421 is shallow, it is easier to clean and dust the muffler cavity 430 connected to the first sound absorption opening 421. The impact of dust on the noise reduction effect during use is reduced, so that the muffler device 400 has a good noise reduction effect.

[0102] In some embodiments of the press chamber of the present utility model, as Figure 6 As shown, the number of the first sound absorbing openings 421 is less than the number of the second sound absorbing openings 422 .

[0103] In this embodiment, since the number of the second sound absorption openings 422 is greater than the number of the first sound absorption openings 421, the number of the muffler cavities 430 connected to the second sound absorption openings 422 is greater than the number of the muffler cavities 430 connected to the first sound absorption openings 421. In addition, since the noise of the compressor compartment is mainly low-frequency noise, it is more conducive to the muffler device 400 to reduce the noise of the low-frequency sound waves, which can be more conducive to improving the noise reduction effect of the compressor compartment, thereby reducing the noise generated outward by the refrigeration and freezing device.

[0104] The present invention also provides a refrigeration and freezing device. In some embodiments of the refrigeration and freezing device of the present invention, the refrigeration and freezing device includes a box body and a compressor 500. The box body has a compressor compartment in any of the above embodiments. The compressor 500 is arranged in the installation space 110.

[0105] In this embodiment, the closing plate 700 is connected to the warehouse body 100 through the magnetic device 800 to cover the opening 111 of the installation space 110. The magnetic device 800 makes it difficult for the connection between the closing plate 700 and the warehouse body 100 to be loosened, avoiding the gap between the closing plate 700 and the warehouse body 100 at the opening 111 of the installation space 110, and thus the closing plate 700 and the warehouse body 100 will not collide when the compressor 500 is working, avoiding the noise caused by the collision between the closing plate 700 and the warehouse body 100, thereby improving the user experience. Moreover, compared with the closing plate 700 being connected to the warehouse body 100 by threads, the closing plate 700 is connected to the warehouse body 100 by the magnetic device 800, which also avoids the phenomenon of screws or studs slipping when the refrigeration and freezing device is repaired, resulting in a gap between the closing plate 700 and the warehouse body 100, or even causing the closing plate 700 to be unable to be installed in the warehouse body 100, thereby making the design of the compressor warehouse improve the user experience.
