Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a refrigeration power unit and a refrigerator. Background Technology

[0002] With the development of society and the economy and the improvement of people's living standards, refrigerators have gradually become an indispensable household appliance, and people's requirements for refrigerators are also gradually increasing. In addition to paying attention to the versatility of refrigerator functions and their aesthetic appearance, people are also increasingly demanding low noise levels during operation.

[0003] In related technologies, when a refrigerator is working, the refrigeration system within the refrigeration power unit generates vibrations and noise, affecting the user's daily life. Therefore, noise reduction components are needed to reduce the noise generated during operation. However, current methods for installing noise reduction components in refrigeration power units present problems such as complex installation structures and difficulties in installation and disassembly. Utility Model Content

[0004] In view of this, the present disclosure provides a refrigeration power unit and a refrigerator, which can reduce the noise generated during operation, and the noise reduction component has a simple installation structure and is easy to install and disassemble.

[0005] Specifically, this disclosure is achieved through the following technical solution.

The connector is fixedly connected to the noise reduction component to mount the noise reduction component on the outer bottom wall of the housing, and the noise reduction channel communicates with the opening.

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

[0008] The nacelle assembly's receiving cavity can accommodate refrigeration components such as compressors. When the refrigeration power unit is in use, the compressor and other refrigeration components generate heat. This heat is dissipated through an opening on the bottom wall of the housing, which connects to the receiving cavity, allowing external airflow to exchange with the airflow inside the housing. The refrigeration power unit also generates noise during operation, which can be transmitted outside the housing through the opening. Noise reduction components are installed on the outer bottom wall of the housing, with their noise reduction channels connected to the openings, thus reducing noise from the refrigeration power unit. The noise reduction components are mounted to the outer bottom wall of the housing via connectors. During installation, the connectors are fixed to the outer bottom wall of the housing, and the noise reduction components are securely connected to the connectors to secure the noise reduction components to the outer bottom wall of the housing. This connector structure is simple, and using connectors to install the noise reduction components to the outer bottom wall of the housing facilitates installation and removal. The connectors can be modularly manufactured, and the installation method is standardized, improving the installation efficiency of the noise reduction components.

[0019] Alternatively, the connector can be welded and fixed to the outer bottom wall of the housing.

[0020] Alternatively, the connector can be integrally molded with the housing.

[0037] The technical solutions in the embodiments (or "implementations") of this disclosure 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.

[0038] If this disclosure uses terms relating to directional indications or positional relationships (e.g., 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 accompanying drawings); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, terms such as "first" and "second" in this disclosure are used only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0039] 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.

[0040] In related technologies, when a refrigerator is working, the refrigeration system within the refrigeration power unit generates vibrations and noise, affecting the user's daily life. Therefore, noise reduction components are needed to reduce the noise generated during operation. However, current methods for installing noise reduction components in refrigeration power units present problems such as complex installation structures and difficulties in installation and disassembly.

[0041] Therefore, it is necessary to provide a refrigeration power unit and a refrigerator that can reduce the noise generated by the refrigeration power unit without affecting the heat dissipation inside the refrigeration power unit. At the same time, the installation structure of the noise reduction component is simple, and the installation and disassembly are easy, which can improve the assembly efficiency of the refrigeration power unit and the refrigerator.

[0042] To better understand the refrigeration power device of this disclosure, it will be illustrated using a refrigerator in which the refrigeration power device is applied.

[0043] 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 300. The refrigeration power unit 300 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.

[0044] like Figure 2 as well as Figure 3As shown, in some embodiments, the refrigeration power unit 300 includes a housing assembly 310 and a refrigeration assembly 320, with the refrigeration assembly 320 disposed within the housing assembly 310. The housing assembly 100 has at least one storage cavity 110, which is spaced apart from the housing assembly 310, and the housing assembly 310 is located at the bottom of the housing assembly 100. Thus, the refrigeration assembly 320 disposed within the housing assembly 310 cools the storage cavity 110, providing a low-temperature environment for refrigeration and freezing of the storage cavity 110.

[0045] In some embodiments, the storage cavity 110 is at least one of a refrigeration cavity, a freezing cavity, or a preservation cavity.

[0046] like Figure 2 as well as Figure 3 As shown, in some embodiments, the refrigeration assembly 320 includes a compressor 321 and a cooling fan 322, which are disposed within the housing assembly 310. Thus, when the compressor 321 is operating, the cooling fan 322 enables airflow within the housing assembly 310 to help dissipate the heat generated by the compressor 321 during operation, preventing overheating and ensuring normal operation of the compressor 321.

[0047] like Figures 4 to 7 As shown, in some embodiments, the refrigeration power unit 300 further includes a noise reduction component 330 and a connector 340. The nacelle assembly 310 includes a housing 311, which has a receiving cavity 312. The bottom wall of the housing 311 has an opening 313 communicating with the receiving cavity 312. A compressor 321 is disposed in the housing 311 and located within the receiving cavity 312. The noise reduction component 330 has a noise reduction channel 332. The connector 340 is fixedly disposed on the outer bottom wall of the housing 311. The connector 340 is fixedly connected to the noise reduction component 330 to mount the noise reduction component 330 on the outer bottom wall of the housing 311, and the noise reduction channel 332 communicates with the opening 313.

[0048] Thus, the receiving cavity 312 of the housing assembly 310 can be used to accommodate the refrigeration components 320, such as the compressor 321. When the refrigeration power unit 300 is in use, the refrigeration components 320, such as the compressor 321, generate heat. Through the opening 313 provided on the bottom wall of the housing 311, and the opening 313 communicating with the receiving cavity 312, external airflow exchanges with the airflow inside the receiving cavity 312, thereby dissipating heat from the refrigeration components 320, such as the compressor 321, inside the receiving cavity 312. When the refrigeration power unit 300 is operating, it generates noise, which can be transmitted to the outside of the housing 311 through the opening 313. Noise reduction is achieved by using a noise reduction component 330 on the outer bottom wall of the housing 311, with the noise reduction channel 332 of the noise reduction component 330 communicating with the opening 313. The noise reduction component 330 is installed on the outer bottom wall of the housing 311 via a connector 340. During the installation of the noise reduction component 330, the connector 340 is fixed to the outer bottom wall of the housing 311, and the noise reduction component 330 is fixedly connected to the connector 340 to achieve the installation of the noise reduction component 330 on the outer bottom wall of the housing 311. The connector 340 has a simple structure, and using it to install the noise reduction component 330 to the outer bottom wall of the housing 311 facilitates the installation and removal of the noise reduction component 330. The connector 340 can be modularly manufactured, and the installation method is standardized, which can improve the installation efficiency of the noise reduction component 330.

[0049] It should be noted that the noise reduction component 330 can be implemented in various ways, including integral molding and separate manufacturing and reassembly.

[0050] It should be noted that there are various ways to implement the molding process of the noise reduction component 330, including but not limited to co-extrusion, compression molding and injection molding.

[0051] like Figure 3 as well as Figure 4 As shown, in some embodiments, there are multiple openings 313, including air inlets 3132 and air outlets 3131. The air inlets 3132 and air outlets 3131 are respectively connected to the receiving cavity 312. The air inlets 3132 and air outlets 3131 are respectively connected to the noise reduction channel 332. Thus, when the refrigerator 10 is operating, the compressor 321 and other refrigeration components 320 generate heat, and external airflow enters and exits the receiving cavity 312 through the air inlets 3132 and air outlets 3131 respectively, to dissipate heat from the compressor 321 and other refrigeration components 320 within the receiving cavity 312.

[0052] like Figure 3 as well as Figure 4 As shown, in some embodiments, the noise reduction element 330 includes two elements, which are arranged opposite to each other, and their noise reduction channels 332 are respectively connected to the port 313.

[0053] In some embodiments, the noise reduction element 330 includes four elements, which surround the outer bottom wall of the housing 311 and their noise reduction channels 332 are respectively connected to the opening 313.

[0054] When the refrigerator 10 is installed, the compartment assembly 310 is located at the bottom of the cabinet assembly 100, and the noise reduction component 330 is set on the outer bottom wall of the housing 311 of the compartment assembly 310, so that the noise reduction component 330 forms a sound cavity with the ground. The noise inside the compartment assembly 310 is transmitted to the sound cavity through the opening 313, and finally to the noise reduction channel 332 of the noise reduction component 330, so that sound insulation and noise reduction are achieved through one or more noise reduction components 330. This method can further improve the noise reduction effect and further reduce the noise transmitted to the outside.

[0055] Understandably, even if multiple noise reduction components 330 are installed on the outer bottom wall of the housing 311, they are all installed using the same connector 340. This standardizes the installation method and helps improve the installation efficiency of the noise reduction components 330.

[0056] like Figures 5 to 7 As shown, in some embodiments, the noise reduction component 330 is provided with a mating portion 331, and the connector 340 includes a connecting portion 341 adapted to the mating portion 331, with the mating portion 331 and the connecting portion 341 fixedly connected. Thus, when the noise reduction component 330 is assembled to the cabin assembly 310, the connector 340 is fixed to the outer bottom wall of the housing 311. By fixing the mating portion 331 of the noise reduction component 330 to the connecting portion 341 of the connector 340, the noise reduction component 330 is installed on the outer bottom wall of the housing 311. Similarly, when it is necessary to remove the noise reduction component 330 from the cabin assembly 310, the mating portion 331 and the connecting portion 341 are disassembled to remove the noise reduction component 330 from the cabin assembly 310. This installation method is simple and easy to install and remove.

[0057] like Figures 5 to 7As shown, in some embodiments, one of the connecting portion 341 and the mating portion 331 is provided with a slide rail 301, and the other is provided with a slide rail 302. The slide rail 301 and the slide rail 302 are slidably connected in a first direction, and the slide rail 301 and the slide rail 302 are fixedly connected in a second direction. The first direction and the second direction are intersecting. Thus, when the noise reduction component 330 is assembled to the nacelle assembly 310, the connecting member 340 is fixed to the outer bottom wall of the housing 311, and the noise reduction component 330 slides relative to the housing 311 in the first direction via the slide rail 301 and the slide rail 302 to install the noise reduction component 330 onto the outer bottom wall of the housing 311. After installation, the slide rail 301 and the slide rail 302 are fixedly connected in the second direction to fix the noise reduction component 330 to the connecting member 340, thereby realizing the installation of the noise reduction component 330 on the outer bottom wall of the housing 311. Similarly, when it is necessary to remove the noise reduction component 330 from the cabin assembly 310, force is applied to the noise reduction component 330, causing it to move relative to the connecting member 340 under the action of the slide rail 301 and the slide path 302, thereby removing the noise reduction component 330 from the cabin assembly 310. This installation method is simple and easy to install and remove.

[0058] It should be noted that one of the connecting part 341 and the mating part 331 is provided with a slide rail 301, and the other is provided with a slide rail 302. This includes the connecting part 341 being provided with a slide rail 301 and the mating part 331 being provided with a slide rail 302.

[0059] It should be noted that the first direction is Figure 3 The X direction is shown, and the second direction is... Figure 3 Y direction shown.

[0060] like Figures 6 to 8As shown, in some embodiments, one of the slide rail 301 and the slide rail 302 is provided with a connecting groove 303, and the other is provided with a connecting body 304 adapted to the connecting groove 303. The connecting groove 303 and the connecting body 304 cooperate to restrict the movement of the slide rail 301 and the slide rail 302 in the second direction. Thus, when the noise reduction component 330 is assembled to the housing assembly 310, the connecting member 340 is fixed to the outer bottom wall of the housing 311. The connecting groove 303 and the connecting body 304 cooperate to allow the slide rail 302 to cooperate with the slide rail 301, so that the noise reduction component 330 and the connecting member 340 can slide relative to each other in the first direction, and finally the noise reduction component 330 is installed on the outer bottom wall of the housing 311. After installation, the connecting groove 303 and the connecting body 304 cooperate to restrict the movement of the slide rail 301 and the slide rail 302 in the second direction, so that the noise reduction component 330 and the connecting member 340 are fixedly connected, thereby realizing that the noise reduction component 330 is installed on the outer bottom wall of the housing 311. Similarly, when it is necessary to remove the noise reduction component 330 from the cabin assembly 310, force is applied to the noise reduction component 330 to cause relative movement between the connecting groove 303 and the connecting body 304, thereby removing the noise reduction component 330 from the cabin assembly 310. This installation method is simple and easy to install and remove.

[0061] It should be noted that one of the slide rail 301 and the slide rail 302 is provided with a connecting groove 303, and the other is provided with a connecting body 304 adapted to the connecting groove 303. This includes the slide rail 301 being provided with a connecting groove 303, the slide rail 302 being provided with a connecting body 304 adapted to the connecting groove 303, and the slide rail 301 being provided with a connecting body 304 adapted to the connecting groove 303.

[0062] like Figures 5 to 7 As shown, in some embodiments, the slide rail 301 includes a mounting opening 3011 and a first sidewall 3012. The mounting opening 3011 and the first sidewall 3012 are disposed opposite each other along a first direction, and the slide rail 302 can be mounted on the slide rail 301 through the mounting opening 3011. Thus, when the noise reduction component 330 is assembled to the cabin assembly 310, the connector 340 is fixed to the outer bottom wall of the housing 311, and the slide rail 302 engages with the slide rail 301 through the mounting opening 3011 and moves relative to the slide rail 301. By setting a first sidewall 3012 that is opposite to the mounting port 3011 in the first direction, when the slide rail 302 and the slide track 301 slide into place, the slide rail 302 can abut against the first sidewall 3012. On the one hand, this can serve as a reminder that the installation is in place, and on the other hand, it can prevent the slide rail 302 and the slide track 301 from moving too far relative to each other, which would cause the slide rail 302 and the slide track 301 to disengage. This improves the reliability of the noise reduction component 330 installed in the nacelle assembly 310.

[0063] like Figure 4 as well as Figure 5As shown, in some embodiments, when the noise reduction component 330 is installed onto the cabin assembly 310, the slide rail 302 abuts against the first sidewall 3012. Thus, after the noise reduction component 330 is installed, the slide rail 302 abuts against the first sidewall 3012, ensuring that the noise reduction component 330 is properly installed and improving the reliability of the noise reduction component 330's installation onto the cabin assembly 310.

[0064] like Figures 5 to 7 As shown, in some embodiments, the slide rail 301 further includes a second sidewall 3013 and a third sidewall 3014 disposed opposite to the second sidewall 3013. The second sidewall 3013 and the third sidewall 3014 are each provided with a connecting groove 303. The slide rail 302 includes connecting bodies 304 corresponding to the connecting grooves 303. Thus, by providing connecting grooves 303 on the oppositely disposed second sidewall 3013 and third sidewall 3014, and providing connecting bodies 304 corresponding to the connecting grooves 303 on the slide rail 302, when the noise reduction component 330 is assembled into the cabin assembly 310, the connecting bodies 304 on both sides of the slide rail 302 can respectively cooperate with the connecting grooves 303 of the second sidewall 3013 and the third sidewall 3014. This improves the reliability of the relative movement between the slide rail 302 and the slide rail 301, avoids or reduces the possibility of disengagement, and improves the connection reliability between the slide rail 302 and the slide rail 301.

[0065] In some embodiments, the refrigeration power unit 300 further includes a sound insulation layer (not shown), which is disposed on at least one of the side wall of the connecting groove 303 or the connector 304, and sandwiched between the side wall of the connecting groove 303 and the connector 304. Thus, by disposing of the sound insulation layer on at least one of the side wall of the connecting groove 303 or the connector 304, when the noise reduction component 330 is installed on the nacelle assembly 310, the sound insulation layer can be sandwiched between the side wall of the connecting groove 303 and the connector 304, thereby preventing noise generated by the refrigeration power unit 300 from being output to the outside through the gap between the connecting groove 303 and the connector 304, which helps to reduce the noise of the refrigeration power unit 300 and improve the user experience.

[0066] It should be noted that the sound insulation layer being disposed on at least one of the side wall of the connecting groove 303 or the connecting body 304 includes the sound insulation layer being disposed on the side wall of the connecting groove 303, the sound insulation layer being disposed on the connecting body 304, or the sound insulation layer being disposed on both the side wall of the connecting groove 303 and the connecting body 304.

[0067] It should be noted that there are various ways to implement sound insulation layers, including but not limited to sound-absorbing cotton and foam.

[0068] It should be noted that there are various ways to fix the connector 340 to the outer bottom wall of the housing 311, including screw fixing, snap fixing, adhesive fixing and riveting fixing, etc.

[0069] In some embodiments, the refrigeration power unit 300 further includes fasteners (not shown), and the connector 340 has a connecting hole adapted to the fastener. The fastener passes through the connecting hole and is fixedly connected to the outer bottom wall of the housing 311, thereby achieving a fixed connection between the connector 340 and the outer bottom wall of the housing 311. Thus, when the noise reduction component 330 is assembled to the nacelle assembly 310, the fastener passes through the connecting hole of the connector 340 to achieve a fixed connection with the outer bottom wall of the housing 311, thereby achieving a fixed connection between the connector 340 and the outer bottom wall of the housing 311. Using fasteners to fix the connector 340 to the outer bottom wall of the housing 311 results in a simple structure and easy installation.

[0070] It should be noted that there are many ways to implement fasteners, including screws, rivets, bolts, etc.

[0071] In some embodiments, the connector 340 is bonded to the outer bottom wall of the housing 311. This bonding method for fixing the connector 340 to the housing 311 is simple and provides high reliability.

[0072] In some embodiments, the connector 340 is welded to the outer bottom wall of the housing 311. This welding method for fixing the connector 340 to the housing 311 is simple and provides high reliability.

[0073] In some embodiments, the connector 340 is integrally formed with the housing 311. Thus, by integrally forming the connector 340 with the housing 311, the assembly steps of the refrigeration power unit 300 can be reduced, and the assembly efficiency of the refrigeration power unit 300 can be improved.

[0074] like Figure 7 as well as Figure 8 As shown, in some embodiments, the noise reduction component 330 has a slide 301, and the connector 340 includes a slide rail 302. The slide 301 and the slide rail 302 cooperate to achieve a fixed connection between the noise reduction component 330 and the connector 340.

[0075] like Figure 7As shown, in some embodiments, the noise reduction component 330 is provided with multiple noise reduction channels 332, which are spaced apart. One end of each noise reduction channel 332 is connected to the opening 313, and the other end is closed. Thus, when noise is transmitted to the noise reduction component 330, on the one hand, the noise reduction component 330 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 332 in the noise reduction component 330, noise can enter the noise reduction channels 332. Because one end of each noise reduction channel 332 is closed, when the noise enters the noise reduction channel 332 and propagates within the closed channel, the sound wave energy is absorbed or reflected by the wall of the noise reduction channel 332, thereby reducing the noise intensity. This noise reduction component 330 has a good noise reduction effect, which is beneficial to improving the user experience.

[0076] like Figure 7 as well as Figure 8 As shown, in some embodiments, the connector 340 is provided with a clearance groove 342. Thus, when the connector 340 is installed to the outer bottom wall of the nacelle, the clearance groove 342 of the connector 340 can avoid the outer bottom wall of the nacelle, thereby avoiding interference during the installation of the connector 340 and improving the installation reliability of the connector 340.

[0077] like Figure 7 As shown, in some embodiments, the depths between at least two noise reduction channels 332 are unequal. Thus, researchers have found in experiments that different depths of the noise reduction channels 332 can reduce noise at different frequencies. By providing multiple noise reduction channels 332 in the noise reduction device 330, and ensuring that the depths between at least two noise reduction channels 332 are unequal, noise at different frequencies can be reduced more effectively, thereby further improving the noise reduction effect of the noise reduction device 330.

[0078] It should be noted that the unequal depth between at least two noise reduction channels 332 can mean that the noise reduction device 330 includes several noise reduction channels 332, of which at least two noise reduction channels 332 have unequal depths, and there are noise reduction channels 332 with equal depths. Alternatively, it can mean that the depths of several noise reduction channels 332 are all unequal.

[0079] In some embodiments, a portion of the noise reduction channel 332 of the noise reduction component 330 can be labyrinthine in shape. That is, a portion of the noise reduction channel 332 can have an opening to the outside, and the channel within the noise reduction component 330 has a tortuous path, thus forming a labyrinthine noise reduction channel 332. In this way, by setting the noise reduction channel 332 to a labyrinthine shape, it is beneficial to reduce noise over a wider range of noise frequencies, thereby improving the noise reduction effect.
