Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of household appliances, and in particular, to a refrigeration power device and a refrigerator. BACKGROUND

[0002] With the development of social economy and the improvement of people's living standards, the refrigerator has gradually become an indispensable household appliance in people's daily life, and people's requirements for the refrigerator have gradually increased. In addition to the functional diversity and the aesthetic appearance of the refrigerator, people also have higher requirements for the low noise of the refrigerator during operation.

[0003] In the related art, when the refrigerator is working, the refrigeration system in the compressor compartment will produce noise during operation, which will affect the normal life of the user. Since the compressor compartment needs to be cooled during the operation of the refrigeration system, there is currently no effective solution that can both reduce the noise of the compressor compartment assembly and not affect the cooling of the compressor compartment. UTILITARIAN CONTENT

[0004] Therefore, the present disclosure provides a refrigeration power device and a refrigerator, which can reduce the generated noise and do not affect the cooling, thereby improving the user experience.

[0005] Specifically, the present disclosure is implemented through the following technical solutions.

[0006] According to a first aspect of the embodiments of the present disclosure, a refrigeration power device is provided, which comprises a machine compartment assembly, a compressor and a plurality of noise reduction pieces. The machine compartment assembly comprises a shell. The shell is provided with a containing cavity. The bottom wall of the shell is provided with an air inlet and an air outlet. The air inlet and the air outlet are respectively communicated with the containing cavity. The compressor is arranged in the shell and located in the containing cavity. The plurality of noise reduction pieces comprises a first noise reduction piece and a second noise reduction piece. The first noise reduction piece and the second noise reduction piece are respectively arranged on the outer bottom wall of the shell along the depth direction of the containing cavity. The first noise reduction piece and the second noise reduction piece are oppositely arranged along the length direction of the shell and form a noise reduction space. The air inlet and the air outlet are respectively communicated with the noise reduction space.

[0007] The technical solutions provided by the embodiments of the present disclosure can include the following beneficial effects:

[0008] The refrigeration power device uses the accommodating cavity of the machine compartment assembly to accommodate the refrigeration components such as the compressor. When the refrigeration components such as the compressor work, heat is generated.

The first noise reduction member and the second noise reduction member are arranged in a length direction of the shell to form a noise reduction space. The air inlet and the air outlet are communicated with the noise reduction space, so that the noise generated by the machine compartment assembly enters the noise reduction space through the air inlet and the air outlet, and the noise reduction member reduces the noise generated by the machine compartment assembly, thereby reducing the noise generated by the refrigeration power device.

[0045] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0046] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0047] With the development of society and the economy and the improvement of people's living standards, refrigerators have gradually become an indispensable household appliance. Furthermore, people's requirements for refrigerators are also gradually increasing. In addition to focusing on the versatility of refrigerator functions and their aesthetic appearance, people are also demanding lower noise levels during operation.

[0048] In related technologies, when a refrigerator is working, the refrigeration system inside the compressor compartment generates vibrations and noise, affecting the user's daily life. Since the compressor compartment also needs to dissipate heat during operation, there is currently no effective solution that can reduce noise in the compressor compartment components without compromising heat dissipation within the compartment.

[0049] Therefore, it is necessary to provide a refrigeration power unit 30 and a refrigerator 10, which can reduce the noise generated by the refrigeration power unit 30 and does not affect the heat dissipation inside the refrigeration power unit 30, thereby improving the user experience.

[0050] To better understand the refrigeration power unit 30 of this application, it will be described using a refrigerator 10 in which the refrigeration power unit 30 is applied.

[0051] like Figures 1 to 3 As shown, a refrigerator 10 is provided, which includes a cabinet assembly 100, a door assembly 200, and a refrigeration power unit 30. The refrigeration power unit 30 is disposed on the cabinet assembly 100, and the door assembly 200 is movably connected to the cabinet assembly 100 to open or close the cabinet assembly 100.

[0052] like Figure 1 as well as Figure 2 As shown, in some embodiments, the refrigerator 10 includes a refrigeration assembly 400, and the refrigeration power unit 30 includes a compartment assembly 300, with the refrigeration assembly 400 disposed within the compartment assembly 300. The cabinet assembly 100 has at least one storage cavity 110, which is spaced apart from the compartment assembly 300, and the compartment assembly 300 is located at the bottom of the cabinet assembly 100. Thus, the refrigeration assembly 400 disposed within the compartment assembly 300 cools the storage cavity 110, providing a low-temperature environment for refrigeration and freezing of the storage cavity 110.

[0053] like Figure 1 as well as Figure 2 As shown, in some embodiments, the refrigeration assembly 400 includes a compressor 410 and a cooling fan 420, which are disposed within the housing assembly 300. Thus, when the compressor 410 is operating, the cooling fan 420 enables airflow within the housing assembly 300 to help dissipate the heat generated by the compressor 410 during operation, preventing overheating and ensuring normal operation of the compressor 410.

[0054] like Figures 3 to 5As shown, in some embodiments, the nacelle assembly 300 includes a housing 310 and a plurality of noise reduction components 303. The housing 310 has a receiving cavity 311. The bottom wall of the housing 310 is provided with an air inlet 312 and an air outlet 313 spaced apart. The air inlet 312 and the air outlet 313 are respectively connected to the receiving cavity 311. The plurality of noise reduction components 303 include a first noise reduction component 320 and a second noise reduction component 330. The first noise reduction component 320 and the second noise reduction component 330 extend along the depth direction of the receiving cavity 311 and are disposed on the outer bottom wall of the housing 310. The first noise reduction component 320 and the second noise reduction component 330 are arranged opposite to each other along the length direction of the housing 310 and form a noise reduction space 301. The air inlet 312 and the air outlet 313 are respectively connected to the noise reduction space 301.

[0055] Thus, when the refrigerator 10 is operating, the compressor 410 and other refrigeration components 400 generate heat. By providing an air inlet 312 and an air outlet 313 at intervals on the bottom wall of the housing 310, and by connecting the air inlet 312 and air outlet 313 to the receiving cavity 311, external airflow enters and exits the receiving cavity 311 through the air inlet 312 and air outlet 313, respectively, to dissipate heat from the compressor 410 and other refrigeration components 400 within the receiving cavity 311. During operation, it generates noise, which can be transmitted to the outside of the housing components 300 through the air inlet 312 and air outlet 313. By providing a first noise reduction component 320 and a second noise reduction component 330 on the outer bottom wall of the housing 310, and by extending the first noise reduction component 320 and the second noise reduction component 330 along the depth direction of the receiving cavity 311, the first noise reduction component 320 and the second noise reduction component 330 are arranged opposite each other along the length direction of the housing 310, forming a noise reduction space 301. By connecting the air inlet 312 and air outlet 313 to the noise reduction space 301, the noise generated by the nacelle assembly 300 during operation enters the noise reduction space 301 through the air inlet 312 and air outlet 313. The noise reduction component 303 then reduces the noise generated by the nacelle assembly 300, thereby reducing the noise of the refrigeration power unit 30 during operation. This method reduces the noise generated by the refrigeration power unit 30 without affecting heat dissipation within the refrigeration power unit 30, thus improving the user experience.

[0056] It should be noted that the depth direction of the receiving cavity 311 is as follows: Figure 5 As shown in the Z direction, the length direction of the housing 310 is as follows: Figure 5 The X direction is shown.

[0057] Specifically, when the refrigerator 10 is installed, the compartment assembly 300 is located at the bottom of the cabinet assembly 100, and the noise reduction component 303 is set on the outer bottom wall of the shell 310 of the compartment assembly 300, so that the noise reduction space 301 forms a sound cavity with the ground. The noise inside the compartment assembly 300 is transmitted to the sound cavity through the air inlet 312 and the air outlet 313, so that the first noise reduction component 320 and the second noise reduction component 330 can perform sound insulation and noise reduction. This method can further improve the noise reduction effect and further reduce the noise transmitted to the outside.

[0058] like Figure 5 as well as Figure 6 As shown, in some embodiments, the plurality of noise reduction components 303 further includes a third noise reduction component 340. The third noise reduction component 340 extends along the length of the housing 310 and is disposed on the outer bottom wall of the housing 310. The first noise reduction component 320, the third noise reduction component 340, and the second noise reduction component 330 are connected in sequence to form a noise reduction space 301. Thus, by extending the third noise reduction component 340 along the length of the housing 310 and disposing it on the outer bottom wall of the housing 310, the first noise reduction component 320, the third noise reduction component 340, and the second noise reduction component 330 are connected in sequence to form a noise reduction space 301. By using three noise reduction components 303 to form a noise reduction space 301, the sound absorption and sound insulation effect of the housing component 300 can be further improved, the noise reduction effect can be improved, and the user's experience of the refrigerator 10 can be further improved. When the refrigerator 10 is installed, the noise reduction space 301, the bottom wall of the housing 310, and the ground form a sound cavity, which achieves a better noise reduction effect.

[0059] In some embodiments, the third noise reduction component 340 is disposed relative to the door assembly 200 near the back of the housing assembly 100. Thus, the noise reduction component 303 is not disposed on the front side of the housing assembly 100, and the air inlet 312 and air outlet 313 can communicate with the outside through the openings on the front side, thereby improving the heat dissipation efficiency of the compressor 410, cooling fan 420, etc. inside the housing assembly 300.

[0060] like Figure 5 as well as Figure 7 As shown, in some embodiments, the plurality of noise reduction components 303 further includes a fourth noise reduction component 350. The fourth noise reduction component 350 extends along the length of the housing 310 and is disposed on the outer bottom wall of the housing 310. The first noise reduction component 320, the third noise reduction component 340, the second noise reduction component 330, and the fourth noise reduction component 350 are sequentially connected and surround the outer bottom wall of the housing 310. In this way, by using the first noise reduction component 320, the third noise reduction component 340, the second noise reduction component 330, and the fourth noise reduction component 350 sequentially connected and surrounding the outer bottom wall of the housing 310, the noise generated by the cabin assembly 300 can enter the noise reduction space 301, and the noise reduction components 303 surrounding the outer bottom wall of the housing 310 can be better utilized for sound absorption and insulation, achieving a better noise reduction effect.

[0061] like Figure 8 as well as Figure 9 As shown, in some embodiments, the noise reduction component 303 includes a mounting wall 3031, and the noise reduction component 303 is mounted on the outer bottom wall of the housing 310 via the mounting wall 3031. Thus, when the noise reduction component 303 is installed in the engine compartment, the noise reduction component 303 is mounted on the outer bottom wall of the housing 310 via the mounting wall 3031, and this installation method is simple and easy to implement.

[0062] It should be noted that there are several ways to install the mounting wall 3031 on the housing 310 assembly, including screw fixing, snap fixing, adhesive fixing, and riveting fixing, etc.

[0063] It should be noted that there are multiple ways to implement the noise reduction component 303, including integral molding and separate manufacturing and reassembly.

[0064] It should be noted that there are various ways to implement the molding process of noise reduction component 303, including but not limited to co-extrusion, compression molding and injection molding.

[0065] In some embodiments, the mounting wall 3031 is bonded and fixed to the outer bottom wall of the nacelle. This method is easy to implement and simple to execute.

[0066] like Figure 8 as well as Figure 9 As shown, in some embodiments, the mounting member is provided with a mounting slot, through which the mounting member can be installed in the refrigerator 10. Thus, the mounting member is installed in the refrigerator 10 via the mounting slot, enabling the noise reduction device to be installed in the refrigerator 10. This method is easy to implement and simple to achieve.

[0067] like Figure 9 as well as Figure 10 As shown, in some embodiments, the noise reduction component 303 is provided with multiple noise reduction channels 304, which are spaced apart. One end of each noise reduction channel 304 is connected to the noise reduction space 301, while the other end is closed. Thus, when noise is transmitted to the noise reduction component 303, on the one hand, the noise reduction component 303 isolates the noise from the outside world, preventing the noise from being transmitted to the outside. On the other hand, by providing multiple noise reduction channels 304 in the noise reduction component 303, noise can enter the noise reduction channels 304. Because one end of each noise reduction channel 304 is closed, when the noise enters the noise reduction channel 304 and propagates within the closed channel, the sound wave energy is absorbed or reflected by the wall of the noise reduction channel 304, thereby reducing the noise intensity. This noise reduction component 303 has a good noise reduction effect, which is beneficial to improving the user experience.

[0068] like Figure 10 as well as Figure 11As shown, in some embodiments, the noise reduction component 303 further includes a first sidewall 3032 disposed adjacent to the mounting wall 3031. The first sidewall 3032 is provided with a plurality of noise reduction channels 304.

[0069] like Figure 9 as well as Figure 12 As shown, in some embodiments, the noise reduction component 303 further includes a second sidewall 3033 disposed opposite to the mounting wall 3031, and the second sidewall 3033 is provided with a plurality of noise reduction channels 304. Thus, by providing a plurality of noise reduction channels 304 on the second sidewall 3033 disposed opposite to the mounting wall 3031, the noise reduction effect of the noise reduction component 303 is improved, thereby enhancing the user experience.

[0070] It should be noted that, as Figure 9 as well as Figure 10 As shown, the noise reduction component 303 can simultaneously have multiple noise reduction channels 304 formed in the first sidewall 3032 and the second sidewall 3033. Alternatively, it can be as follows: Figure 14 As shown, multiple noise reduction channels 304 are opened on a certain side wall. For example, multiple noise reduction channels 304 are opened on the first side wall 3032 or the second side wall 3033.

[0071] like Figures 10 to 12 As shown, in some embodiments, the mounting wall 3031 is provided with a clearance groove 3034. Thus, when the noise reduction device is installed on the outer bottom wall of the cabin, the clearance groove 3034 of the mounting wall 3031 can avoid the outer bottom wall of the cabin, thereby avoiding interference during the installation of the noise reduction device and improving the installation reliability of the noise reduction device.

[0072] like Figure 11 as well as Figure 12 As shown, in some embodiments, the depths between at least two noise reduction channels 304 are unequal. Thus, researchers have found in experiments that different depths of the noise reduction channels 304 can reduce noise at different frequencies. By providing multiple noise reduction channels 304 in the noise reduction device 303, and ensuring that the depths between at least two noise reduction channels 304 are unequal, noise at different frequencies can be reduced more effectively, thereby further improving the noise reduction effect of the noise reduction device 303.

[0073] It should be noted that the unequal depth between at least two noise reduction channels 304 can mean that the noise reduction component 303 includes several noise reduction channels 304, of which at least two noise reduction channels 304 have unequal depths, and there are noise reduction channels 304 with equal depths. Alternatively, it can mean that the depths of several noise reduction channels 304 are all unequal.

[0074] In some embodiments, the inner wall of the noise reduction channel 304 is provided with protrusions. Thus, when the refrigerator 10 is working, when its noise is transmitted to the noise reduction channel 304, the protrusions on the inner wall of the noise reduction channel 304 can further reduce noise, thereby improving the noise reduction effect of the noise reduction device.

[0075] Of course, in other embodiments, the inner wall of the noise reduction channel 304 may have a recess. In this way, when the refrigerator 10 is working, when its noise is transmitted to the noise reduction channel 304, the recess on the inner wall of the noise reduction channel 304 can further play a role in noise reduction, thereby improving the noise reduction effect of the noise reduction device.

[0076] like Figure 12 as well as Figure 13 As shown, in some embodiments, the noise reduction channel 304 includes a first channel 305 and a second channel 306 connected to the first channel 305. The first channel 305 and the second channel 306 are connected at an acute angle, a right angle, or an obtuse angle. Thus, by configuring the noise reduction channel 304 to be formed by connecting the first channel 305 and the second channel 306, and with the first channel 305 and the second channel 306 connected at an acute angle, a right angle, or an obtuse angle, when noise is transmitted to the noise reduction channel 304, the included angle between the first channel 305 and the second channel 306 can be used to further reduce the noise, thereby further improving the noise reduction effect of the noise reduction component 303.

[0077] like Figure 12 as well as Figure 13 As shown, in some embodiments, the first channel 305 and the second channel 306 are connected in an L-shape in the cross-section of the noise reduction element 303 in the width direction. Thus, the first channel 305 and the second channel 306 are connected at a right angle in the cross-section of the noise reduction element 303 in the width direction. Researchers have found in experiments that the noise reduction effect of the noise reduction channel 304 is better when the first channel 305 and the second channel 306 are connected at a right angle.

[0078] Of course, in some other embodiments, the connection between the first channel 305 and the second channel 306 in the width direction cross-section of the noise reduction component 303 can also be in the shape of ∠, ∧, ∨, ∩, ∪, ┌, ┐, etc.

[0079] In some embodiments, the connection between the first channel 305 and the second channel 306 is arc-shaped. This facilitates the manufacturing of the noise reduction channel 304 and also improves the noise reduction effect of the noise reduction channel 304.

[0080] It should be noted that the cross-section of the noise reduction component 303 in the width direction is... Figure 13 The view shown.

[0081] like Figure 12 as well as Figure 13As shown, in some embodiments, the depth of the first channel 305 is 3mm to 15mm. Thus, researchers have found from experiments that when the depth of the first channel 305 is 3mm to 15mm, it has a better noise reduction effect on the frequency of noise within the cabin assembly 300.

[0082] Optionally, the depth of the first channel 305 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc.

[0083] In one example, the depth of the first channel 305 is 8mm.

[0084] like Figure 12 as well as Figure 13 As shown, in some embodiments, the depth of the second channel 306 is 20mm to 425mm. Thus, researchers have found through experiments that when the depth of the second channel 306 is 20mm to 425mm, it has a better noise reduction effect on the frequency of noise within the naval component 300.

[0085] Optionally, the depth of the second channel 306 can be 20mm, 222mm, 24mm, 25mm, 28mm, 30mm, 35mm, 38mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 68mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, 215mm, 220mm, 223mm, 250mm, 275mm, 300mm, 325mm, 350mm, 375mm, 400mm, 425mm, etc.

[0086] like Figure 11 As shown, in some embodiments, the height of the noise reduction channel 304 is 3mm to 20mm. Thus, researchers have found from experiments that when the depth of the first channel 305 is 3mm to 20mm as the height of the noise reduction channel 304, it has a better noise reduction effect on the frequency of noise within the cabin assembly 300.

[0087] Optionally, the height of the noise reduction channel 304 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, 15.5mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc.

[0088] In one example, the height of noise reduction channel 304 is 15mm.

[0089] It should be noted that the height of noise reduction channel 304 is Figure 11 As shown in diagram a, the depth of the first channel 305 is... Figure 13 As shown in b, the depth of the second channel 306 is Figure 13 c is shown.

[0090] In some embodiments, a portion of the noise reduction channel 304 of the noise reduction component 303 can be labyrinth-shaped. That is, a portion of the noise reduction channel 304 can have an opening to the outside, and the channel within the noise reduction component 303 has a tortuous path, thus forming a labyrinth-shaped noise reduction channel 304. In this way, by setting the noise reduction channel 304 to a labyrinth shape, it is beneficial to reduce noise over a wider range of noise frequencies, thereby improving the noise reduction effect.

[0091] like Figure 8 As shown, in some embodiments, the nacelle assembly 300 further includes a mounting base 360 ​​disposed on the outer bottom wall of the housing 310. The height of the noise reduction component 303 is greater than or equal to the height of the mounting base 360. Thus, when the refrigerator 10 is installed, the refrigerator 10 is mounted on the ground using the mounting base 360. By making the height of the noise reduction component 303 greater than or equal to the height of the mounting base 360, after the refrigerator 10 is installed, the noise reduction component 303 abuts against the ground, allowing the noise reduction component 303 to fit against the ground, reducing the direct transmission of noise from the refrigeration power unit 30 into the noise reduction space 301 after entering through the air inlet 312 and air outlet 313.

[0092] like Figure 1 as well as Figure 2 As shown, in some embodiments, a portion of the noise reduction component 303 protrudes from the mounting base 360. Thus, by making a portion of the noise reduction component 303 protrude from the mounting base 360, the noise reduction component 303 can abut against the ground during refrigerator 10 installation, thus reducing the direct transmission of noise from the refrigeration power unit 30 to the outside.

[0093] It should be noted that there are various ways to implement a flexible abutment, including but not limited to rubber, silicone, etc.

[0094] like Figure 8 as well as Figure 9As shown, in some embodiments, the nacelle assembly 300 further includes a baffle strip 302 disposed on the outer bottom wall of the housing 310. At least a portion of the baffle strip 302 is located between the air inlet 312 and the air outlet 313, thus isolating the air inlet 312 and the air outlet 313. In this way, by providing a baffle strip 302 on the outer bottom wall of the housing 310 and placing at least a portion of the baffle strip 302 between the air inlet 312 and the air outlet 313, turbulent airflow between the air inlet 312 and the air outlet 313 is avoided, thereby improving the heat dissipation efficiency inside the refrigeration power unit 30.

[0095] like Figures 5 to 8 As shown, in some embodiments, one of the first noise reduction component 320 and the second noise reduction component 330 forms an air inlet duct with the wind deflector 302 and the bottom wall of the housing 310, and the air inlet 312 communicates with the outside through the air inlet duct. The other of the first noise reduction component 320 and the second noise reduction component 330 forms an air outlet duct with the wind deflector 302 and the bottom wall of the housing 310, and the air outlet 313 communicates with the outside through the air outlet duct. Thus, by forming an air inlet duct with one of the first noise reduction component 320 and the second noise reduction component 330 with the wind deflector 302 and the bottom wall of the housing 310, the air inlet 312 communicates with the outside through the air inlet duct. When the refrigerator 10 is working, outside air can enter the air inlet 312 through the air inlet duct and enter the receiving cavity 311 of the refrigeration components 400, such as the compressor 410, inside the refrigeration components 400 to dissipate heat. The other of the first noise reduction component 320 and the second noise reduction component 330, together with the wind deflector 302 and the bottom wall of the housing 310, forms an air outlet duct, through which the air outlet 313 connects to the outside. This allows the airflow within the housing cavity 311 of the nacelle assembly 300 to enter the air outlet duct through the air outlet 313 and be transferred to the outside, thereby achieving heat dissipation for the nacelle assembly 300. The formation of both inlet and outlet air outlet ducts improves heat dissipation efficiency, reduces airflow turbulence between inlet and outlet, and enhances the reliability of heat dissipation.
