Description

Technical Field

[0001] This application relates to the technical field of clothes dryers, and more particularly to a compressor noise reduction housing and a clothes dryer. Background Technology

[0002] In existing technologies, the compressor of a clothes dryer, as one of its core components, is increasingly exhibiting vibration and noise problems during operation. Noise levels typically reach 60-70 dB, severely impacting user experience and the comfort of the living environment. The root cause of this problem lies in the compressor's direct exposure within the dryer's internal cavity, lacking effective vibration isolation and sound-absorbing structural design. Traditional noise reduction methods, such as wrapping the compressor with a single piece of sound-absorbing cotton, while absorbing some noise, have several limitations. First, the installation process of sound-absorbing cotton is complex and inconvenient to maintain, increasing production and usage costs. Second, wrapping the compressor with sound-absorbing cotton may affect its heat dissipation, leading to decreased compressor efficiency and even safety hazards. Finally, for suppressing high-frequency noise, a single piece of sound-absorbing cotton is often insufficient, failing to meet the increasingly demanding noise reduction requirements. Utility Model Content

[0003] The purpose of this application is to provide a compressor noise reduction housing with efficient vibration isolation and sound absorption effects, which can effectively solve the vibration and noise problem of the dryer compressor during operation, while also taking into account the convenience of installation and maintenance.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On one hand, a compressor noise reduction housing is provided, comprising: a base, a housing, a top cover, and a vibration isolation component.

[0024] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0027] like Figures 1 to 6As shown, this embodiment provides a compressor noise reduction housing, including: a base 1, a housing 2, a top cover 3, and a vibration isolation component 4. The housing 2 covers the outer wall of the compressor and is installed above the base 1. The top cover 3 is installed on the top of the housing 2, and the vibration isolation component 4 is installed below the base 1. The interior of the housing 2 is hollow, forming a cavity. The cavity consists of an inner sound insulation layer and an outer sound insulation layer from the inside to the outside. The inner sound insulation layer is filled with glass wool, and the outer sound insulation layer is filled with polyurethane foam.

[0028] Based on the above scheme, in terms of working principle, the noise-reducing housing achieves efficient vibration isolation and sound absorption through a carefully designed structure. Specifically, the housing 2 is installed on the outer wall of the compressor, either tightly fitted to the compressor or with an appropriate gap, forming a closed space. The interior of the housing 2 is hollow, consisting of an inner sound insulation layer filled with glass wool and an outer sound insulation layer filled with polyurethane foam, from the inside out. When the compressor is running, the vibrations and noise generated are first absorbed by the glass wool in the inner sound insulation layer, effectively attenuating low- and mid-frequency noise. Subsequently, the remaining noise passes through the inner sound insulation layer and is further absorbed and isolated by the polyurethane foam in the outer sound insulation layer, especially significantly suppressing high-frequency noise. At the same time, the vibration isolation component 4 under the base 1 absorbs and reduces the vibration of the compressor, preventing the vibration from being transmitted to the external environment through the base 1.

[0029] In terms of beneficial effects, this noise-reducing housing has significant advantages. First, through the dual design of the inner and outer sound insulation layers, and the cooperation of the vibration isolation component 4, it achieves efficient isolation and absorption of compressor vibration and noise, significantly reducing noise levels and improving the user experience and living environment comfort. Second, the noise-reducing housing adopts a modular design; the base 1, housing 2, top cover 3, and vibration isolation component 4 can all be independently disassembled and installed, facilitating maintenance and replacement and reducing production and usage costs. Furthermore, the housing 2 has an appropriate gap or is designed with heat dissipation channels between it and the compressor, ensuring proper heat dissipation during compressor operation and avoiding decreased efficiency or safety hazards. Finally, this noise-reducing housing can be customized according to different models and specifications of compressors, exhibiting strong adaptability and versatility to meet the needs of different users.

[0030] Furthermore, the housing 2 includes two symmetrical sub-shell components 201, each containing a relatively independent cavity. The two sub-shell components 201 can be independently installed on either side of the compressor, forming two relatively independent sound-insulating cavities. When the compressor is running, the noise and vibration generated are absorbed and isolated by the inner sound-insulating layer (glass wool) and the outer sound-insulating layer (polyurethane foam) within the two sub-shell components 201, respectively. This split design makes the sound insulation effect more uniform because noise and vibration are attenuated separately by the two independent sound-insulating cavities during propagation, thereby further improving the overall vibration isolation and sound absorption effect. This design brings several advantages. First, the design of the sub-shell components 201 makes the installation and disassembly of the housing 2 more convenient and quick. Maintenance or replacement of a single sub-shell component 201 can be performed without disassembling the entire housing 2, greatly improving maintenance efficiency and convenience. Second, the two relatively independent cavities provide better sound insulation because noise and vibration are attenuated twice independently during propagation, thereby further reducing the noise level. In addition, this split design enhances the adaptability and versatility of housing 2, making it easier to customize and adjust for different models and specifications of compressors, thus meeting a wider range of needs.

[0031] Furthermore, the base 1 has a limiting groove 101 that engages with and limits the bottom of the two shell components 201, while the top cover 3 is designed as two symmetrical cover components 301. These two cover components 301 are tightly connected to the two shell components 201 through a clever positioning structure. Specifically, the positioning structure includes positioning protrusions 202 respectively disposed on the upper part of the outer wall of the two shell components 201, and two positioning portions 302 disposed on the outer peripheral wall of the cover components 301. The positioning portions 302 are provided with positioning grooves 303 that engage with the positioning protrusions 202 for positioning.

[0032] In this design, when installing the noise-reducing housing, the two housing components 201 are first placed in the limiting grooves 101 of the base 1. The design of the limiting grooves 101 ensures that the housing components 201 are firmly fixed on the base 1 and will not shift due to compressor vibration. Next, the two cover components 301 are placed on top of the two housing components 201, and the cover components 301 are tightly connected to the housing components 201 through a positioning structure. The cooperation between the positioning protrusion 202 and the positioning groove 303 allows the cover component 301 to be accurately positioned on the housing component 201, ensuring the stability and sealing of the entire noise-reducing housing.

[0033] In terms of beneficial effects, firstly, the limiting groove 101 on the base 1 and the positioning structure on the cover 301 work together to make the installation of the noise-reducing shell more convenient and quick, and the stability after installation is higher, which can effectively prevent the noise-reducing shell from loosening or shifting due to compressor vibration. Secondly, the design of the shell 201 and the cover 301 makes the disassembly and maintenance of the noise-reducing shell easier. A single shell 201 or cover 301 can be replaced or repaired without disassembling the entire noise-reducing shell, which greatly improves the efficiency and convenience of maintenance.

[0034] Furthermore, the base 1 is provided with a positioning groove 102 that mates with the bottom of the compressor. When installing the noise-reducing housing, first align the bottom of the compressor with the positioning groove 102 on the base 1, then gently lower it so that the bottom of the compressor is fully embedded in the positioning groove 102. The design of the positioning groove 102 ensures that the compressor can be accurately positioned on the base 1 and will not shift due to vibration or external force, thus ensuring a tight fit between the noise-reducing housing and the compressor. Subsequently, the two housing components 201 are placed in the limiting grooves 101 of the base 1, and the entire noise-reducing housing is fixed in place by the cover component 301 and the positioning structure. This positioning groove 102 improves the connection stability between the noise-reducing housing and the compressor, ensuring that the noise-reducing housing can effectively isolate and absorb the vibration and noise generated by the compressor. Moreover, the design of the positioning groove 102 makes the installation of the noise-reducing housing more convenient and quick, because the user only needs to align the bottom of the compressor with the positioning groove 102 and lower it, without the need for complex adjustments and alignment.

[0035] In some embodiments, the vibration isolation assembly 4 includes a base plate 401, a plurality of first elastic elements 402, and fixing blocks 403 corresponding to the first elastic elements 402. The plurality of fixing blocks 403 are arranged circumferentially around the base plate 401, and the fixing blocks 403 are inclined relative to one side of the base 1. The base 1 has a fixing groove corresponding to the fixing block 403 on one side of the base plate 401, and the groove surface of the fixing groove is parallel to the inclined surface of the fixing block 403. The first elastic elements 402 are disposed between the fixing blocks 403 and the fixing groove. The plurality of fixing blocks 403 are arranged circumferentially around the base plate 401, forming a stable support structure. The fixing blocks 403 are inclined relative to one side of the base 1 and are parallel to the groove surface of the fixing groove on the base 1. The first elastic elements 402 are cleverly disposed between the fixing blocks 403 and the fixing groove. When the vibration generated by the compressor is transmitted to the base 1, these first elastic elements 402 will undergo elastic deformation, thereby absorbing and damping the vibration. Because the inclined design of the fixing block 403 matches the groove surface of the fixing groove, this structure not only provides stable support, but also allows the base 1 to make small displacements within a certain range, further absorbing vibration energy.

[0036] In this design, firstly, the effective use of the first elastic element 402 significantly improves the vibration isolation effect, greatly reducing the impact of compressor vibration on other parts of the dryer or the external environment. Secondly, the inclined design of the fixing block 403 and the fixing groove makes the vibration isolation assembly 4 easier to align and fix during installation, improving the convenience and accuracy of installation. Furthermore, this vibration isolation assembly 4 also has good durability and reliability because both the first elastic element 402 and the fixing block 403 are carefully designed and made of selected materials, capable of withstanding long-term vibration and wear.

[0037] Furthermore, the vibration isolation assembly 4 also includes a second elastic element 404, which is vertically disposed between the middle of the base plate 401 and the middle of the base 1. When the compressor is running, the vibration it generates is transmitted to the vibration isolation assembly 4 through the base 1. At this time, not only does the first elastic element 402 play a role in absorbing and damping the vibration, but the second elastic element 404 also plays a crucial supporting and buffering role. Since the second elastic element 404 is located in the middle of the base plate 401 and the base 1, it can effectively withstand and disperse the vertical vibration generated by the compressor, preventing the vibration energy from being directly transmitted to other parts of the dryer or the external environment. The second elastic element 404 enhances the vertical support capacity of the vibration isolation assembly 4, making the noise reduction shell more stable when subjected to the vertical vibration of the compressor. At the same time, the second elastic element 404 and the first elastic element 402 work together to form a more comprehensive and efficient vibration isolation system, which can more effectively isolate and absorb vibration energy from various directions.

[0038] Optionally, the porosity of the glass wool is between 30% and 70%, with the outer layer having a higher porosity than the inner layer. By controlling the porosity of the glass wool between 30% and 70%, sufficient sound absorption performance is ensured while avoiding a decrease in material strength due to excessive porosity. Furthermore, the porous structure of the glass wool gives it excellent sound absorption properties. When sound waves encounter the glass wool, they undergo multiple reflections and scatterings within its pores, thus converting sound wave energy into heat energy, achieving a sound insulation effect. The design of a higher porosity in the outer layer compared to the inner layer is for better absorption and dispersion of high-frequency sound waves. High-frequency sound waves have shorter wavelengths and are more easily scattered in materials with larger pores; therefore, using glass wool with a larger porosity in the outer layer can more effectively absorb high-frequency noise.

[0039] On the other hand, a dryer is also provided, including a compressor noise reduction housing as described above.
