Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and more particularly to a window air conditioner. Background Technology

[0002] Air conditioning piping is an important component that connects the compressor and the two air conditioning units (i.e., the evaporator and the condenser). The reliability of air conditioning piping is essential to ensuring the normal operation of air conditioning products.

[0003] However, during the compressor's start-up, operation, and shutdown, the air conditioning piping is constantly subjected to the compressor's vibration excitation force, causing corresponding stress and vibration in the piping. This can easily lead to cracks and leaks in the air conditioning piping, resulting in the air conditioner failing to operate and generating noise. Moreover, during the transportation and handling of air conditioning products, the air conditioning piping is also subjected to various impact forces such as bumps and drops, causing deformation of the air conditioning piping and collisions with surrounding components, resulting in abnormal noise. This is especially true for window air conditioners with limited piping space, where the air conditioning piping is more likely to collide with surrounding components and cause abnormal noise. Utility Model Content

[0004] This application discloses a window air conditioner that can suppress the vibration and stress of the air conditioning piping while reducing the noise of the compressor itself. This helps to reduce the risk of air conditioning piping rupture and reduce the noise of the air conditioning piping. At the same time, it can also constrain the air conditioning piping and solve the noise problem caused by the deformation of the air conditioning piping.

[0005] To achieve the above objectives, this application discloses a window air conditioner, which includes:

[0006] The housing has an indoor unit and an outdoor unit connected together;

[0007] An indoor heat exchanger is disposed in the indoor unit.

[0008] An outdoor heat exchanger is installed in the outdoor unit.

[0009] The compressor is installed in the outdoor unit.

[0010] Air conditioning piping, wherein the air conditioning piping is connected between the compressor and the outdoor heat exchanger, and / or, the air conditioning piping is connected between the compressor and the indoor heat exchanger; and,

[0011] A sound insulation device, wherein the sound insulation device is sleeved on the outer periphery of the compressor, the sound insulation device having:

[0012] A first soundproof cavity, the first soundproof cavity having opposing first top openings and first bottom openings, the compressor passing through the first soundproof cavity; and...

[0013] A second soundproof cavity, the second soundproof cavity having a second top opening;

[0014] The air conditioning pipe is inserted into the second soundproof cavity through the second top opening, and one end of the air conditioning pipe extends out of the second soundproof cavity through the second top opening and is connected to the top of the compressor.

[0015] In the window air conditioner provided in this application embodiment, the compressor is at least partially disposed in the first sound insulation cavity of the sound insulation device, which is equivalent to the sound insulation device at least partially wrapping the compressor circumferentially. This allows the sound insulation device to absorb the compressor's vibration and reduce the noise emitted by the compressor. Simultaneously, the air conditioning piping is inserted into the second sound insulation cavity, which is equivalent to the sound insulation device also at least partially wrapping the air conditioning piping circumferentially. Therefore, when the compressor transmits vibrations to the air conditioning piping during operation, the vibration energy of the air conditioning piping is absorbed by the sound insulation device, reducing the vibration and stress of the air conditioning piping. This helps to reduce the risk of air conditioning piping breakage and reduce the noise of the air conditioning piping. Furthermore, since the sound insulation device is fitted around the compressor, it can be confined by the compressor. Inserting the air conditioning piping into the second sound insulation cavity of the sound insulation device can constrain the air conditioning piping, reducing deformation caused by transportation or drops. This solves the noise problem caused by the air conditioning piping deforming and colliding with surrounding components, thus ensuring the operational reliability of the air conditioning piping within a narrow piping space.

[0016] In other words, this application innovatively designs the structure of the compressor sound insulation device, enabling it to reduce the vibration and deformation of the air conditioning piping in addition to its sound absorption function, thereby reducing the noise of the air conditioning piping. Furthermore, in a narrow piping space, it can also reduce the probability of the air conditioning piping colliding with surrounding components, ensuring the operational reliability of the air conditioning piping.

[0017] As an optional implementation, in an embodiment of this application, the sound insulation device includes:

[0018] A soundproof sleeve, the interior of which defines a first soundproof cavity, a first top opening formed at the top of the soundproof sleeve, and a first bottom opening formed at the bottom of the soundproof sleeve; and,

[0019] A side soundproof cover is connected to the outside of the soundproof sleeve, and the soundproof sleeve and the soundproof sleeve together form a second soundproof cavity. The top of the side soundproof cover and the top of the soundproof sleeve together form a second top opening.

[0020] The sound insulation device with the above structure is relatively simple and has a low cost. Moreover, the second sound insulation cavity is formed by the outer periphery of the side sound insulation cover and the sound insulation sleeve. By reusing the sound insulation sleeve, the overall volume of the sound insulation device can be made smaller, making it suitable for window air conditioners with limited internal space.

[0021] As an optional implementation, in the embodiments of this application, the side soundproof cover and the soundproof sleeve are connected by stitching.

[0022] Compared to the method of fixing the side soundproof cover to the soundproof sleeve with Velcro, the stitching connection method can fix the side soundproof cover to the soundproof sleeve more securely, improve the connection stability between the side soundproof cover and the soundproof sleeve, and prevent the side soundproof cover from accidentally falling off the soundproof sleeve due to the vibration of the compressor and air conditioning piping.

[0023] As an optional implementation, in the embodiments of this application, the sound insulation sleeve and the side sound insulation cover are integrally formed. This not only allows the side sound insulation cover to be more securely fixed to the sound insulation sleeve, improving the connection stability between the side sound insulation cover and the sound insulation sleeve, and preventing the side sound insulation cover from accidentally detaching from the sound insulation sleeve due to vibrations of the compressor and air conditioning piping, thus preventing accidental detachment of the side sound insulation cover; it also allows the sound insulation sleeve to be more securely fitted onto the outer periphery of the compressor, preventing the sound insulation sleeve from falling off the compressor.

[0024] As an optional implementation, in an embodiment of this application, the top of the soundproof sleeve protrudes beyond the top of the side soundproof cover in the axial direction of the soundproof sleeve.

[0025] That is, the top of the soundproof sleeve is longer than the top of the side soundproof cover, which allows the soundproof sleeve to form a guide portion above the second top opening. This allows the air conditioning pipe to be moved along the guide portion at the top of the soundproof sleeve to the second top opening before being inserted into the second soundproof cavity. During this process, the guide portion at the top of the soundproof sleeve can be used to indicate and guide the air conditioning pipe to quickly align with the second top opening, making it easier for the air conditioning pipe to be inserted into the second soundproof cavity.

[0026] As an optional implementation, in the embodiments of this application, the thickness of the sound insulation sleeve is 6mm-12mm. When the sound insulation sleeve is controlled within the above range, it can avoid the problem that the sound insulation sleeve has poor vibration reduction and sound absorption effect due to the side sound insulation cover being too thin; it can also avoid the situation that the side sound insulation cover is too thick, which would increase the cost.

[0027] And / or, the thickness of the side soundproof cover is 6mm-12mm. When the side soundproof cover is controlled within the above range, it can avoid the problem that the soundproof sleeve has poor vibration reduction and sound absorption effect due to the side soundproof cover being too thin; it can also avoid the situation that the side soundproof cover is too thick, which would increase the cost.

[0028] As an optional implementation, in an embodiment of this application, the air conditioning piping includes:

[0029] The first pipe section is connected to the compressor;

[0030] The second pipe section is connected to the indoor heat exchanger and / or the outdoor heat exchanger;

[0031] The third pipe section is a U-shaped bend, which is connected between the first pipe section and the second pipe section. The bend of the third pipe section extends into the second sound insulation cavity from the second top opening.

[0032] With the above-mentioned structure, during actual production and assembly, the sound insulation device can be first installed on the compressor, and then the bent section of the third pipe segment can be inserted into the second sound insulation cavity of the sound insulation device from the second top opening, which facilitates the assembly between the air conditioning piping and the sound insulation device.

[0033] As an optional implementation, in an embodiment of this application, the second sound insulation cavity further has a second bottom opening disposed opposite to the second top opening.

[0034] In this way, one end of the air conditioning piping can be connected to the compressor, and the other end can be inserted into the second sound insulation cavity from the second top opening and extend out of the second sound insulation cavity from the second bottom opening to connect with the indoor heat exchanger and / or the outdoor heat exchanger; or, when the air conditioning piping includes a U-shaped bend, the bend section of the U-shaped bend extends into the second sound insulation cavity from the second top opening. By making the second sound insulation cavity also have a second bottom opening opposite to the second top opening, in addition to the U-shaped bend with a shorter length being able to be accommodated in the second sound insulation cavity, even if the length of the U-shaped bend is longer than the axial dimension of the second sound insulation cavity in the sound insulation sleeve, the bend section of the U-shaped bend can extend out of the second sound insulation cavity from the second bottom opening, so that the second sound insulation cavity can also allow U-shaped bends with a length greater than their axial dimension in the sound insulation sleeve to pass through, that is, U-shaped bends with a length greater than their axial dimension in the sound insulation sleeve can also be accommodated in the second sound insulation cavity, thereby improving the applicability of the second sound insulation cavity.

[0035] As an optional implementation, in an embodiment of this application, the window air conditioner further includes a mounting bracket, the bottom of the compressor is fixed to the bottom wall of the outdoor unit via the mounting bracket, and the bottom of the sound insulation device abuts against the mounting bracket.

[0036] This setup, using mounting brackets to support the sound insulation device, raises the device and separates it from the bottom wall of the outdoor unit, preventing direct contact between the device and the bottom wall. This avoids frost on the bottom wall from melting into water and seeping into the device, thus preventing it from affecting the sound absorption and insulation performance.

[0037] As an optional implementation, in the embodiments of this application, the compressor is provided with an exhaust port and an exhaust port, and the sound insulation device has two second sound insulation cavities, which are arranged circumferentially along the first sound insulation cavity;

[0038] The air conditioning piping includes:

[0039] An exhaust pipe is connected to the exhaust port and to the outdoor heat exchanger, and the exhaust pipe extends from one of the second top openings into one of the second sound insulation cavities;

[0040] The return air pipe is connected to the return air port and to the indoor heat exchanger, and the return air pipe extends from another second top opening into another second sound insulation cavity.

[0041] This configuration serves two purposes: firstly, it reduces the vibration and noise of the exhaust piping connecting the compressor and the outdoor heat exchanger, and constrains the exhaust piping to reduce its deformation, thereby minimizing the possibility of collisions between the exhaust piping and surrounding components; secondly, it reduces the vibration and noise of the return gas piping connecting the compressor and the indoor heat exchanger, and constrains the return gas piping to reduce its deformation, thereby minimizing the possibility of collisions between the return gas piping and surrounding components.

[0063] In current air conditioners, the compressor and the two evaporators (evaporator and condenser) are essential core components. The air conditioning piping is a crucial part connecting the compressor and the two evaporators, and its reliability is essential for ensuring the normal operation of the air conditioning product. However, in actual use, air conditioners are frequently found to malfunction due to leaks in the piping, or to cause abnormal noise due to piping colliding with surrounding components, causing significant inconvenience to users.

[0064] Specifically, in related technologies, the excitation forces on air conditioning piping under different operating conditions are quite complex. For example, during the start-up, operation, and shutdown of the air conditioner, the air conditioning piping is constantly subjected to the excitation force of compressor vibration and the impact force of refrigerant, which causes corresponding stress and vibration in the air conditioning piping. This can easily lead to cracks and leaks in the air conditioning piping, causing the air conditioner to fail to operate and generate noise. Moreover, during the transportation and handling of air conditioning products, the air conditioning piping is also subjected to various impact forces such as bumps and drops. Therefore, the design requirements for vibration and stress of air conditioning piping are relatively high, especially for window air conditioners with limited piping space. In addition to ensuring that the vibration and stress of the air conditioning piping meet the requirements, the deformation of the air conditioning piping also faces a severe test.

[0065] As we all know, a window air conditioner is a small air conditioner that can be installed in a window. Its internal space is much smaller than other types of air conditioners (such as floor-standing air conditioners, wall-mounted air conditioners, etc.). The internal components of a window air conditioner are usually arranged more densely, which makes it easier for the air conditioning pipes to collide with surrounding components when they deform, causing abnormal noise.

[0066] In view of this, the present application provides a window air conditioner that can reduce the noise of the compressor itself, suppress the vibration and stress of the air conditioning piping, reduce the risk of air conditioning piping rupture and noise, and also constrain the air conditioning piping to solve the noise problem caused by the deformation of the air conditioning piping.

[0067] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0068] Please see Figure 1 This application discloses a window air conditioner 1000, which is suitable for installation on a window in an indoor environment. Because the window air conditioner 1000 is installed on a window, its installation in the indoor environment is more space-saving, facilitating its placement and providing more reliable performance to meet user needs, thereby improving user comfort.

[0069] In some embodiments, such as Figure 1 and Figure 2 As shown, the window air conditioner 1000 provided in this embodiment includes a housing 100, an indoor heat exchanger 200 disposed in the housing 100, an outdoor heat exchanger 300, a compressor 400, an indoor fan assembly (not shown), and an outdoor fan assembly 500.

[0070] In this application, the housing 100 is primarily adapted to provide assembly space so that the indoor heat exchanger 200, outdoor heat exchanger 300, compressor 400, indoor fan assembly, outdoor fan assembly 500, and other structures within the window air conditioner 1000 can be arranged within the housing 100. This allows the housing 100 to provide a protective enclosure for the indoor heat exchanger 200, outdoor heat exchanger 300, compressor 400, indoor fan assembly, outdoor fan assembly 500, and other structures, preventing damage from external objects or impacts. Consequently, the window air conditioner 100 can achieve higher performance and a longer service life during use.

[0071] Specifically, the housing 100 may have an indoor unit 100a and an outdoor unit 100b connected to each other, wherein an indoor heat exchanger 200 is disposed in the indoor unit 100a, an outdoor heat exchanger 300 is disposed in the outdoor unit 100b, and a compressor 400 is also disposed in the outdoor unit 100b.

[0072] More specifically, the outer casing 100 may include a chassis 100c, a first casing 100d, and a second casing 100e. The first casing 100d and the second casing 100e are both located above the chassis 100c. A portion of the first casing 100d and the chassis 100c constitutes an indoor unit 100a, and the other portion of the second casing 100e and the chassis 100c constitutes an outdoor unit 100b. The indoor heat exchanger 200, the outdoor heat exchanger 300, and the compressor 400 are all mounted on the chassis 100c. In this way, the chassis 100c can provide mounting positions and support for the indoor heat exchanger 200, the outdoor heat exchanger 300, and the compressor 400.

[0073] In this application, the housing 100 is provided with an indoor exhaust vent 11, an indoor return air vent 12, an outdoor air inlet 13, and an outdoor air outlet 14 communicating with its internal space. Specifically, the indoor unit 100a is provided with an indoor exhaust vent 11 and an indoor return air vent 12 communicating with its internal space; the outdoor unit 100b is provided with an outdoor air inlet 13 and an outdoor air outlet 14 communicating with its internal space.

[0074] In this application, the indoor heat exchanger 200 is mainly used for heat exchange with indoor air.

[0075] In this application, the outdoor heat exchanger 300 is mainly used for heat exchange with outdoor air.

[0076] In this application, the compressor 400 is connected to the indoor heat exchanger 200 and the outdoor heat exchanger 300 respectively, wherein the compressor 400, the indoor heat exchanger 200 and the outdoor heat exchanger 300 form a refrigerant circulation loop.

[0077] In this application, the indoor fan assembly may include an indoor volute, a centrifugal impeller, and an indoor motor. The indoor volute is mounted on a chassis and has an air duct inside, which is connected to an indoor exhaust vent. The centrifugal impeller is mounted inside the air duct, and the indoor motor is mounted inside the housing and located outside the air duct. The motor shaft of the indoor motor is connected to the centrifugal impeller, so that the indoor motor can drive the centrifugal impeller to rotate.

[0078] In this application, the outdoor fan assembly 500 may include an outdoor fan 51 and an outdoor motor 52. The outdoor fan 51 is connected to the motor shaft of the outdoor motor 52, so that the outdoor fan 51 can rotate under the drive of the outdoor motor 52.

[0079] For example, the outdoor fan 51 can be mounted on the chassis 100c via the fan bracket 53; at the same time, the outdoor motor 52 can also be mounted on the chassis 100c via the fan bracket 53.

[0080] When the window air conditioner 1000 is working, the operation of the outdoor fan 51 can introduce external airflow into the casing 100 through the outdoor air inlet 13, and form a heat exchange airflow through heat exchange with the refrigerant in the outdoor heat exchanger 300. The heat exchange airflow can be output to the outside through the outdoor air outlet 14 under the drive of the outdoor fan 51. The refrigerant after heat exchange can flow into the indoor heat exchanger 200. Meanwhile, the operation of the centrifugal fan can introduce indoor airflow into the casing 100 through the indoor return air inlet 12, and form a heat exchange airflow through heat exchange with the refrigerant in the indoor heat exchanger 200. The heat exchange airflow can be output to the room through the indoor exhaust outlet 11 under the drive of the centrifugal fan. In this way, the window air conditioner 1000 can deliver air of a suitable temperature to the room, realize the function of the window air conditioner 1000 in regulating the indoor temperature, ensure the normal operation of the window air conditioner 1000, meet the user's usage needs in different scenarios, and improve the user experience.

[0081] Specifically, the window air conditioner 1000 of this embodiment can operate independently. The outdoor heat exchanger 300 can be either an evaporator or a condenser, and the corresponding indoor heat exchanger 200 can be either a condenser or an evaporator. The window air conditioner 1000 can perform a refrigeration cycle using a compressor 400, an expansion valve, a condenser, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, supplying refrigerant to the regulated and heat-exchanged air. The compressor 400 compresses the refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant that has expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor 400. The evaporator can achieve a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material to be cooled. Throughout the entire cycle, the window air conditioner 1000 can regulate the temperature of the indoor space.

[0082] Furthermore, the outdoor fan 51 in this embodiment can accelerate the airflow through the outdoor heat exchanger 300, and the centrifugal fan in this embodiment can accelerate the airflow through the indoor heat exchanger, thereby improving the heat exchange efficiency of the window air conditioner 1000 and improving the working performance of the window air conditioner 1000.

[0083] Please see Figure 2 and Figure 3 The window air conditioner 1000 provided in this application embodiment includes an air conditioning pipe 600, which is connected between the compressor 400 and the outdoor heat exchanger 300, and / or the air conditioning pipe 600 is connected between the compressor 400 and the indoor heat exchanger 200.

[0084] That is to say, the air conditioning piping 600 in this application can be connected between the compressor 400 and the outdoor heat exchanger 300; or, the air conditioning piping 600 can be connected between the compressor 400 and the indoor heat exchanger 200; or, the air conditioning piping 600 can be connected between the compressor 400 and the outdoor heat exchanger 300, and also between the compressor 400 and the indoor heat exchanger 200.

[0085] When the air conditioning piping 600 is connected both between the compressor 400 and the outdoor heat exchanger 300, and also between the compressor 400 and the indoor heat exchanger 200, the air conditioning piping 600 includes an exhaust piping 61 and a return piping 62. The exhaust piping 61 is connected between the compressor 400 and the outdoor heat exchanger 300, and the return piping 62 is connected between the compressor 400 and the indoor heat exchanger 200.

[0086] Specifically, the compressor 400 is provided with an exhaust port 41 and a return port 42. For example, the compressor 400 is provided with an exhaust port 41 and a return port 42. The exhaust pipe 61 is connected to the exhaust port 41 and is connected to the outdoor heat exchanger 300. The return pipe 62 is connected to the return port 42 and is connected to the indoor heat exchanger 200.

[0087] Please see Figure 2 and Figure 3 The window air conditioner 1000 provided in this application embodiment includes a sound insulation device 700. The sound insulation device 700 is sleeved on the outer periphery of the compressor 400, thereby absorbing the vibration of the compressor 400 and reducing the noise emitted by the compressor 400, thus playing a role in sound absorption and sound insulation for the compressor 400.

[0088] In some embodiments, the window air conditioner 1000 further includes a mounting bracket 800, wherein the bottom of the compressor 400 is fixed to the bottom wall of the outdoor unit 100b via the mounting bracket 800, that is, the bottom of the compressor 400 is fixed to the chassis 100c via the mounting bracket 800, and the bottom of the sound insulation device 700 abuts against the mounting bracket 800. Thus, the mounting bracket 800 supports the sound insulation device 700, raising the sound insulation device 700 and separating it from the bottom wall of the outdoor unit 100b, preventing direct contact between the sound insulation device 700 and the bottom wall of the outdoor unit 100b. This prevents frost on the bottom wall of the outdoor unit 100b from melting into water and seeping into the sound insulation device 700, thereby affecting its sound absorption and sound insulation effects.

[0089] In some embodiments, combined with Figure 3 and Figure 5 As shown, the sound insulation device 700 has a first sound insulation cavity 71 and a second sound insulation cavity 72. The first sound insulation cavity 71 has a first top opening 711 and a first bottom opening 712, and the compressor 400 passes through the first sound insulation cavity 71. The second sound insulation cavity 72 has a second top opening 721. An air conditioning pipe 600 is inserted into the second sound insulation cavity 72 through the second top opening 721, and one end of the air conditioning pipe 600 extends out of the second sound insulation cavity 72 through the second top opening 721 and connects to the top of the compressor 400.

[0090] In the window air conditioner 1000 provided in this application embodiment, the compressor 400 is at least partially disposed in the first sound insulation cavity 71 of the sound insulation device 700, which is equivalent to the sound insulation device 700 at least partially enclosing the compressor 400 circumferentially. Therefore, the sound insulation device 700 can absorb the vibration of the compressor 400 and reduce the noise emitted by the compressor 400. Simultaneously, the air conditioning pipe 600 is inserted into the second sound insulation cavity 72, which is equivalent to the sound insulation device 700 also at least partially enclosing the air conditioning pipe 600 circumferentially. Therefore, when the compressor 400 operates and transmits vibrations to the air conditioning pipe 600, the vibration energy of the air conditioning pipe 600 is absorbed by the sound insulation device 700, which can reduce the vibration of the air conditioning pipe 600 and reduce the stress on the air conditioning pipe 600. This helps reduce the risk of air conditioning pipe 600 breaking and reduce the noise of air conditioning pipe 600. At the same time, since the sound insulation device 700 is sleeved on the outer periphery of the compressor 400, the sound insulation device 700 can be limited by the compressor 400. Inserting the air conditioning pipe 600 into the second sound insulation cavity 72 of the sound insulation device 700 can restrain the air conditioning pipe 600, which can reduce the deformation of the air conditioning pipe 600 caused by transportation or dropping. This can solve the noise problem caused by the deformation of the air conditioning pipe 600 and collision with surrounding components (such as compressor 400, outdoor heat exchanger 300, indoor heat exchanger, outdoor fan assembly 500 and indoor fan assembly, etc.). In this way, the operational reliability of the air conditioning pipe 600 can be guaranteed in a narrower pipe laying space.

[0091] In other words, this application innovatively designs the structure of the sound insulation device 700 for the compressor 400, enabling it to reduce the vibration and deformation of the air conditioning piping 600 on the basis of sound absorption, thereby reducing the noise of the air conditioning piping 600. In addition, it can also reduce the probability of the air conditioning piping 600 colliding with surrounding components in a narrow piping space, thus ensuring the operational reliability of the air conditioning piping 600.

[0092] Meanwhile, since the installation of the air conditioning piping 600 is constrained by the sound insulation device 700, the misalignment of the air conditioning piping 600 can be reduced, allowing the air conditioning piping 600 to be installed and arranged according to the target shape, thereby improving the installation consistency of the air conditioning piping 600.

[0093] In some embodiments, such as Figure 5 and Figure 6 As shown, the sound insulation device 700 may have two second sound insulation cavities 72, which are arranged circumferentially along the first sound insulation cavity 71; the exhaust pipe 61 may extend into one of the second sound insulation cavities 72 from one of the second top openings 721; and the return pipe 62 may extend into the other second sound insulation cavity 72 from the other second top opening 721.

[0094] This configuration serves two purposes: firstly, it reduces the vibration and noise of the exhaust pipe 61 connecting the compressor 400 and the outdoor heat exchanger 300, and constrains the exhaust pipe 61 to reduce its deformation, thereby minimizing the possibility of the exhaust pipe 61 colliding with surrounding components; secondly, it reduces the vibration and noise of the return gas pipe 62 connecting the compressor 400 and the indoor heat exchanger, and constrains the return gas pipe 62 to reduce its deformation, thereby minimizing the possibility of the return gas pipe 62 colliding with surrounding components.

[0095] In some embodiments, the sound insulation device 700 may be made of sound insulation cotton, foam, or other materials with elastic deformation capabilities, such as silicone, plastic, rubber, etc.

[0096] In some embodiments, the sound insulation device 700 may include a sound insulation sleeve 700a and a side sound insulation cover 700b. The interior of the sound insulation sleeve 700a defines a first sound insulation cavity 71. A first top opening 711 is formed at the top of the sound insulation sleeve 700a, and a first bottom opening 712 is formed at the bottom of the sound insulation sleeve 700a. The side sound insulation cover 700b is connected to the outside of the sound insulation sleeve 700a, and a second sound insulation cavity 72 is formed between the two sound insulation sleeves. A second top opening 721 is formed between the top of the side sound insulation cover 700b and the top of the sound insulation sleeve 700a.

[0097] The sound insulation device 700 with the above structure has a relatively simple structure and low cost; moreover, the second sound insulation cavity 72 is formed by the outer periphery of the side sound insulation cover 700b and the sound insulation sleeve 700a. By reusing the sound insulation sleeve 700a, the overall volume of the sound insulation device 700 can be made relatively small, so that the sound insulation device 700 can be used in window air conditioners 1000 with relatively limited internal space.

[0098] Optionally, the materials of the soundproof sleeve 700a and the side soundproof cover 700b can be the same or different. When the materials of the soundproof sleeve 700a and the side soundproof cover 700b are the same, for example, both the soundproof sleeve 700a and the side soundproof cover 700b can be made of soundproofing cotton; while when the materials of the soundproof sleeve 700a and the side soundproof cover 700b are different, for example, the material of the soundproof sleeve 700a can be soundproofing cotton and the material of the side soundproof cover 700b can be silicone, or vice versa.

[0099] In some embodiments, the side soundproof cover 700b can be fixedly attached to the outer periphery of the soundproof sleeve 700a using Velcro. However, since Velcro is a surface contact method, relying on microscopic hooks to hold the fibers, the hooks and fibers will be repeatedly pulled under the continuous high-frequency vibration of the compressor 400 and the air conditioning piping 600, which can easily lead to partial detachment. Once detachment begins, it will quickly come loose completely, causing the side soundproof cover 700b to fall off.

[0100] Therefore, in some embodiments, the side soundproof cover 700b and the soundproof sleeve 700a can be connected by stitching. Compared to the side soundproof cover 700b being fixed to the soundproof sleeve 700a with Velcro, the stitching connection allows the side soundproof cover 700b to be more securely fixed to the soundproof sleeve 700a, improving the connection stability between the side soundproof cover 700b and the soundproof sleeve 700a, and preventing the side soundproof cover 700b from accidentally detaching from the soundproof sleeve 700a due to vibration of the compressor 400 and the air conditioning piping 600, thereby preventing the side soundproof cover 700b from accidentally falling off.

[0101] In other words, the stronger the connection stability between the side sound insulation cover 700b and the sound insulation sleeve 700a, the more reliable the constraint of the side sound insulation cover 700b on the air conditioning pipe 600. This can effectively prevent the window air conditioner 1000 from falling or the air conditioning pipe 600 from deforming during transportation. This can avoid friction noise caused by the deformation of the air conditioning pipe 600, such as preventing the air conditioning pipe 600 from colliding with the fan bracket or interfering with the fan blade tip of the outdoor fan 51 after deformation.

[0102] In other embodiments, the sound insulation sleeve 700a and the side sound insulation cover 700b can be integrally formed. This not only allows the side sound insulation cover 700b to be more securely fixed to the sound insulation sleeve 700a, improving the connection stability between the side sound insulation cover 700b and the sound insulation sleeve 700a, and preventing the side sound insulation cover 700b from accidentally detaching from the sound insulation sleeve 700a due to vibrations of the compressor 400 and the air conditioning piping 600, thus preventing the side sound insulation cover 700b from accidentally falling off; it also allows the sound insulation sleeve 700a to be more securely fitted onto the outer periphery of the compressor 400, preventing the sound insulation sleeve 700a from falling off the compressor 400.

[0103] In some embodiments, such as Figure 7 and Figure 8As shown, in the axial direction of the sound insulation sleeve 700a, the top of the sound insulation sleeve 700a protrudes beyond the top of the side sound insulation cover 700b. That is, the top of the sound insulation sleeve 700a extends beyond the top of the side sound insulation cover 700b, thereby forming a guide portion 700a1 above the second top opening 721 of the sound insulation sleeve 700a. This allows the air conditioning pipe 600 to move along the guide portion at the top of the sound insulation sleeve 700a to the second top opening 721 before being inserted into the second sound insulation cavity 72 through the second top opening 721, so that it can be inserted into the second sound insulation cavity 72. During this process, the guide portion at the top of the sound insulation sleeve 700a can indicate and guide the air conditioning pipe 600 to quickly and accurately align with the second top opening 721, facilitating the insertion of the air conditioning pipe 600 into the second sound insulation cavity 72.

[0104] In some embodiments, such as Figure 9 As shown, the thickness d1 of the sound insulation sleeve 700a is 6mm-12mm, for example, 6mm≤d1≤7mm, 7mm≤d1≤8mm, 8mm≤d1≤9mm, 9mm≤d1≤10mm, 10mm≤d1≤11mm, or 11mm≤d1≤12mm, etc. For example, d1 = 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, or 12mm, etc.

[0105] When d1 < 6mm, the thickness of the sound insulation sleeve 700a is too thin, making it difficult to fully absorb the vibration energy of the compressor 400, resulting in poor vibration reduction and sound absorption effects. When d1 > 12mm, the thickness of the sound insulation sleeve 700a becomes too thick, increasing its cost.

[0106] Therefore, when the relationship 6mm≤d1≤12mm is satisfied, the thickness of the sound insulation sleeve 700a can be controlled within a suitable thickness range. This can avoid the problem of poor vibration reduction and sound absorption effect caused by the sound insulation sleeve 700a being too thin, and also avoid the situation of increased cost caused by the sound insulation sleeve 700a being too thick.

[0107] Similarly, in some embodiments, the thickness d2 of the side soundproof enclosure 700b is 6mm-12mm, for example, 6mm≤d2≤7mm, 7mm≤d2≤8mm, 8mm≤d2≤9mm, 9mm≤d2≤10mm, 10mm≤d2≤11mm, or 11mm≤d2≤12mm, etc. Exemplarily, d2 = 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, or 12mm, etc.

[0108] When d2 < 6mm, the side sound insulation cover 700b is too thin, making it difficult to fully absorb the vibration energy of the air conditioning piping 600, resulting in poor vibration reduction and sound absorption effects. When d2 > 12mm, the side sound insulation cover 700b becomes too thick, increasing its cost.

[0109] Therefore, when the relationship 6mm≤d2≤12mm is satisfied, the thickness of the side soundproof cover 700b can be controlled within a suitable thickness range. This can avoid the problem of poor vibration reduction and sound absorption effect of the soundproof sleeve 700a due to the side soundproof cover 700b being too thin, and also avoid the situation of increased cost due to the side soundproof cover 700b being too thick.

[0110] In some embodiments, such as Figure 9 and Figure 10 As shown, the air conditioning piping 600 may include a first pipe section 61a, a second pipe section 61b, and a third pipe section 61c. The first pipe section 61a is connected to the compressor 400, the second pipe section 61b is connected to the indoor heat exchanger and / or the outdoor heat exchanger, and the third pipe section 61c is a U-shaped bend. The third pipe section 61c is connected between the first pipe section 61a and the second pipe section 61b. The bend of the third pipe section 61c extends from the second top opening 721 into the second sound insulation cavity 72.

[0111] When the air conditioning piping 600 with the above structure is assembled in actual production, the sound insulation device 700 can be first installed on the compressor 400, and then the bent section of the third pipe section 61c can be extended from the second top opening 721 into the second sound insulation cavity 72 of the sound insulation device 700, which facilitates the assembly between the air conditioning piping 600 and the sound insulation device 700.

[0112] It should be noted that when the second pipe section 61b is connected to the indoor heat exchanger and the outdoor heat exchanger, the exhaust pipe and the return pipe of the air conditioning piping both include the first pipe section 61a, the second pipe section 61b and the third pipe section 61c. The first pipe section 61a of the exhaust pipe and the first pipe section 61a of the return pipe are respectively connected to the compressor. The second pipe section 61b of the exhaust pipe is connected to the outdoor heat exchanger, and the second pipe section 61b of the return pipe is connected to the indoor heat exchanger.

[0113] Furthermore, the first pipe section 61a and the second pipe section 61b can both be copper pipes, while the third pipe section 61c can be an aluminum pipe and is a U-shaped bend. Specifically, the third pipe section 61c is a U-shaped bend, connecting the first pipe section 61a and the second pipe section 61b, giving the air conditioning piping 600 the characteristics of a cantilever beam. The first pipe section 61a and the second pipe section 61b are connected to the two ends of the U-shaped bend, respectively. The two ends of the U-shaped bend are areas of higher stress, so the first pipe section 61a and the second pipe section 61b are made of copper pipes; the U-shaped bend is an area of ​​lower stress, so the third pipe section 61c is made of aluminum. Aluminum is cheaper than copper, thus maintaining the durability and reliability of the air conditioning piping 600 while significantly reducing costs; moreover, copper resources are far lower than aluminum resources worldwide, and aluminum replacing copper will be a development trend.

[0114] Therefore, the third pipe section 61c is a U-shaped bend, and the first pipe section 61a and the second pipe section 61b are respectively connected to the two ends of the U-shaped bend to form a cantilever beam structure. In areas with low stress, such as the third pipe section 61c, aluminum pipes are used, while in areas with high stress, such as the first pipe section 61a and the second pipe section 61b, copper pipes are used. This ensures the reliability of the air conditioning piping 600 while reducing manufacturing costs. In this application, the third pipe section 61c is a U-shaped bend, that is, the third pipe section 61c includes a bend section 61c1 and two straight pipe sections 61c2. The bend section 61c1 is connected between the two straight pipe sections 61c2, and the two straight pipe sections 61c2 are respectively connected to the first pipe section 61a and the second pipe section 61b.

[0115] In some embodiments, the second soundproof cavity 72 further has a second bottom opening 722 disposed opposite to the second top opening 721. Thus, one end of the air conditioning piping 600 can be connected to the compressor 400, and the other end can be inserted into the second soundproof cavity 72 from the second top opening 721 and extend out of the second soundproof cavity 72 from the second bottom opening 722, extending to connect with the indoor heat exchanger and / or the outdoor heat exchanger 300; or, when the air conditioning piping 600 includes a U-shaped bend, the bend section of the U-shaped bend extends into the second soundproof cavity 72 from the second top opening 721. By making the second soundproof cavity 72 also have a second bottom opening 722 disposed opposite to the second top opening 721, in addition to the shorter U-shaped bend... The tube can be housed in the second soundproof cavity 72. Even if the length of the U-shaped bend is long, and the length of the U-shaped bend is greater than the axial dimension of the second soundproof cavity 72 in the soundproof sleeve 700a, the bend section of the U-shaped bend can extend out of the second soundproof cavity 72 from the second bottom opening 722. This allows the second soundproof cavity 72 to also allow U-shaped bends with a length greater than its axial dimension in the soundproof sleeve 700a to be inserted. In other words, U-shaped bends with a length greater than its axial dimension in the soundproof sleeve 700a can also be housed in the second soundproof cavity 72, thereby improving the applicability of the second soundproof cavity 72.

[0116] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0117] Furthermore, the embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
