Detailed Implementation

[0050] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0051] It should be noted that, for ease of description and understanding, the terms "front," "rear," "up," "down," "left," and "right" in this embodiment refer to the installation state of the air conditioner during normal use. The direction from which the air outlet of the indoor heat exchanger faces the user is considered "front," and the direction away from the user is considered "rear." The vertical direction is the up-down direction, and the direction perpendicular to both the front-back and vertical directions is the left-right direction. For example... Figures 1 to 3 As shown.

[0052] This embodiment provides an air conditioner, which includes a refrigeration system for exchanging heat with indoor and outdoor air to meet cooling or heating needs.

[0053] The refrigeration system includes a compressor, a condenser, a first throttling device, and an evaporator. In this application, the air conditioner performs a refrigeration cycle by using the compressor, condenser, first throttling device, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, supplying conditioned and heat-exchanged air to the indoor and outdoor environments.

[0054] The compressor compresses refrigerant gas at a low temperature and low pressure and discharges the compressed, high-temperature, high-pressure 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.

[0055] The first throttling device is, for example, an expansion valve, which causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand 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.

[0056] An evaporator achieves a cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0057] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0058] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0059] An air conditioner consists of an indoor unit and an outdoor unit, which can be configured as an integrated unit or a split unit.

[0060] The air conditioner includes, but is not limited to, integrated units and split units. An integrated unit refers to an air conditioner where the outdoor and indoor units are integrated into one unit. A split unit refers to an air conditioner where the outdoor and indoor units are separate units. For example, this embodiment will use an integrated unit as a specific example.

[0061] The complete unit can be, for example, a window unit, a portable unit, a rooftop unit, or a kitchen air conditioner.

[0062] Please see Figure 20The air conditioner in this application includes a refrigerant circulation loop, which circulates the refrigerant within a circuit consisting of a compressor 10, a condenser, a first throttling device 30, and an evaporator. One of the condenser and evaporator is an outdoor heat exchanger 20, and the other is an indoor heat exchanger 40. The indoor heat exchanger 40 exchanges heat with the indoor air, and the outdoor heat exchanger 20 exchanges heat with the outdoor air, thereby fulfilling the air conditioner's cooling or heating requirements.

[0063] The indoor unit also includes an indoor fan 92, which is located near the return air vent or the air outlet of the indoor heat exchanger 40. It is used to deliver the heat-exchanged air to the indoor unit. The indoor fan 92 has multiple speed settings to change the airflow speed at the air outlet.

[0064] An air guide plate is installed at the air outlet. By changing its relative rotation angle with the air outlet, the air guide plate adjusts the direction of the airflow through the air outlet, thereby affecting the stratification of indoor air temperature.

[0065] The outdoor unit also includes an outdoor fan 70, which is located on one side of the outdoor heat exchanger 20 to deliver outdoor air to the outdoor heat exchanger 20 for heat exchange. In the embodiment shown in this application, the air conditioner also includes a controller, which is a device that generates operation control signals based on instruction operation codes and timing signals to instruct the air conditioner to execute control commands. For example, in response to a received power-on or power-off command from a user, the controller can execute an operation related to the object selected by the power-on or power-off command.

[0066] As mentioned in the background art, the sound insulation and noise reduction effect of the partition 5611 installed between the indoor and outdoor sides in the related art is insufficient. The reason for this problem is that the partition 5611 is usually set as a single-layer sound insulation structure, so the sound insulation effect is poor. Even if it is proposed to add sound insulation and heat insulation units to the outdoor side of the partition 5611, the sound insulation and heat insulation units include, for example, sound insulation and heat insulation sponge layers. The sound insulation and heat insulation sponge layers occupy the outdoor side space, and because they are close to the electrical control box located on the indoor side, they are easily heated by the electrical control box, which may lead to a fire risk, resulting in low safety.

[0067] Based on the above reasons, this application provides an air conditioner that can effectively improve noise reduction and sound insulation, make reasonable use of space, and has a high level of safety.

[0068] The following is for reference. Figures 1-20 This application describes an air conditioner according to an embodiment of the present application.

[0069] See Figures 1 to 3 An embodiment of the present application provides an air conditioner including a housing 80. The housing 80 has a receiving space.

[0070] For example, the air conditioner also includes an indoor unit. The indoor unit is disposed within a housing space. Specifically, the indoor unit includes a bracket 51, an indoor heat exchanger 40, and an indoor fan 92. The bracket 51 is connected to the outer casing 80, specifically, for example, to the bottom wall of the outer casing 80. The bracket 51 serves to support and carry the indoor heat exchanger 40 and the indoor fan 92. The outer casing 80 is provided with a first air inlet 801. Optionally, the first air inlet 801 may include, but is not limited to, multiple air inlets. The indoor fan 92 is located on the side of the indoor heat exchanger 40 opposite to the first air inlet 801. When the indoor fan 92 is operating, it draws indoor air from the first air inlet 801 into the outer casing 80 and through the indoor heat exchanger 40, so that the indoor heat exchanger 40 exchanges heat with the indoor air.

[0071] Please see Figure 3 and Figure 8 For example, the air conditioner also includes an outdoor unit. The outdoor unit is disposed within the housing space. Specifically, the outdoor unit includes a compressor 10, an electronic control assembly 94, an outdoor heat exchanger 20, and an outdoor fan 70. The housing 80 is provided with a second air inlet 802. Optionally, the second air inlet 802 may include, but is not limited to, various forms such as air inlets. The outdoor fan 70 is used to draw outdoor air from the second air inlet 802 into the housing space and through the outdoor heat exchanger 20, so that the outdoor heat exchanger 20 exchanges heat with the outdoor air.

[0072] For example, the air conditioner also includes a sound insulation component 56. The sound insulation component 56 is disposed within the accommodating space, located between the indoor and outdoor areas. Specifically, the sound insulation component 56 is positioned on the side of the indoor fan 92 facing away from the first air inlet 801, that is, on the side of the indoor fan 92 facing the outdoor fan 70. The indoor fan 92 and the indoor heat exchanger 40 are located on one side of the sound insulation component 56, while the compressor 10, the electrical control component 94, and the outdoor fan 70 are located on the other side. Thus, the indoor fan 92 is isolated from the compressor 10, the electrical control component 94, the outdoor heat exchanger 20, and the outdoor fan 70 by the sound insulation component 56, achieving a sound insulation effect and effectively preventing noise generated by the compressor 10 and the outdoor fan 70 during operation from entering the room.

[0073] For example, the sound insulation component 56 may be configured as a multi-layer sound insulation layer, which is arranged sequentially along the front and rear direction of the air conditioner to form multiple sound insulation layers. This can effectively block the noise generated by the outdoor fan 70 and the compressor 10 when they are working, thereby reducing the indoor noise level and improving the user experience.

[0074] Please see Figure 3 , Figures 9 to 13Optionally, the multi-layer sound insulation includes a first sound insulation layer 561. The first sound insulation layer 561 is closer to the outside than the other sound insulation layers. The first sound insulation layer 561 includes a partition 5611, which is made of a flame-retardant material. More specifically, the flame-retardant material is preferably a metal material, which has high strength, high temperature resistance, and is not easily combustible. Optionally, the partition 5611 is a sheet metal part.

[0075] The accommodating space is divided into an indoor cavity and an outdoor cavity by a first sound insulation layer 561. Specifically, the accommodating space is divided into an indoor cavity and an outdoor cavity by a middle partition 5611.

[0076] In use, the aforementioned air conditioner, on the one hand, utilizes the sound insulation component 56 to separate the indoor and outdoor spaces, i.e., to separate the indoor fan 92, compressor 10, and outdoor fan 70. Furthermore, due to the inclusion of multiple sound insulation layers arranged sequentially along the front-to-back direction of the air conditioner, it forms multiple layers of sound insulation, resulting in a better sound insulation effect. This effectively prevents noise generated by the compressor 10 and outdoor fan 70 from entering the room, reducing the impact of noise from the compressor 10 and outdoor fan 70 on the indoor environment. On the other hand, the multiple sound insulation layers include a first sound insulation layer 561, which is closer to the outdoor space than the other sound insulation layers. The first sound insulation layer 561 includes a partition 5611 made of flame-retardant material, which divides the accommodating space into an outdoor cavity and an indoor cavity, effectively reducing noise. Additionally, the side of the partition 5611 closest to the outdoor space is designated as the outdoor side, and the other side is designated as the indoor side. Since the partition 5611 is closest to the outside, the other sound insulation layers are located on the indoor side, not the outdoor side. This means they do not occupy the space of the outdoor layer, allowing for more rational use of space. Furthermore, the other sound insulation layers are far from the electrical control components 94 located on the outdoor side, which effectively reduces the risk of fire caused by heat to the other sound insulation layers, resulting in higher safety and achieving rational use of the space.

[0077] Optionally, the number of sound insulation layers may include, but is not limited to, two, three, four, or more layers; the specific number is not limited here. The more sound insulation layers there are, the better the sound insulation effect of the sound insulation component 56, but the space occupied and material cost of the sound insulation component 56 also increase accordingly. To control material costs while ensuring sound insulation performance, the number of sound insulation layers in this embodiment is, for example, two to four layers. Specifically, this example uses two sound insulation layers, but it is not limited to this; the sound insulation layer can also be set to more layers.

[0078] For example, the multi-layer sound insulation includes not only a first sound insulation layer 561, but also a second sound insulation layer 562. The second sound insulation layer 562 can block the noise of the compressor 10 and the outdoor fan 70 from being transmitted from back to front into the room.

[0079] Optionally, the sound insulation component 56 further includes sound insulation material. The sound insulation material is disposed, for example, between any two adjacent sound insulation layers. Specifically, in this embodiment, the sound insulation material is disposed between the first sound insulation layer 561 and the second sound insulation layer 562. The sound insulation material can further enhance the sound insulation effect. The sound insulation material includes, but is not limited to, at least one of sound insulation film, sound insulation cotton, or sound insulation board.

[0080] For example, the second sound insulation layer 562 is installed on the side of the indoor heat exchanger 40, indoor fan 92, and bracket 51 facing the outside. Thus, the second sound insulation layer 562, installed on the side of the indoor heat exchanger 40, indoor fan 92, and bracket 51 facing the outside, acts as a guide, allowing indoor air to flow towards the front of the outer casing 80 after heat exchange with the indoor heat exchanger 40 and then be discharged. Therefore, it is equivalent to a duct back panel, eliminating the need for a duct back panel on the side of the indoor fan 92 facing the outside. This results in a compact structure, improved space utilization, reduced overall size, and lower material costs.

[0081] Please see Figures 11 to 13 In one specific embodiment, the indoor fan 92 is, for example, a cross-flow fan. The cross-flow fan includes a volute 921. The volute 921 includes a first split shell facing away from the outside of the room. The volute 921 also includes a second split shell 9211. The second split shell 9211 faces the outside of the room and is connected to the first split shell. The second split shell 9211 and the first split shell cooperate to form an air duct. When the cross-flow fan is working, indoor air exchanges heat with the indoor heat exchanger 40 and then enters the air duct, before being discharged outwards through the volute 921 into the room.

[0082] Specifically, the second sound insulation layer 562 includes a main sound insulation panel 5621. The bottom of the main sound insulation panel 5621 extends toward the bottom of the outer casing 80 and is connected, for example, to the bottom wall of the outer casing 80. The top of the main sound insulation panel 5621 is connected to the second split shell 9211. Optionally, the main sound insulation panel 5621 and the second split shell 9211 are an integrated structure, specifically, for example, integrally injection molded. Both the second split shell 9211 and the main sound insulation panel 5621 can achieve good sound insulation effect, effectively preventing noise generated on the outdoor side from being transmitted into the room. The second split shell 9211 can also be understood as a part of the second sound insulation layer 562. That is, the second split shell 9211 includes not only the main sound insulation panel 5621, but also the second split shell 9211. In this way, the second sound insulation layer 562 can not only provide sound insulation and noise reduction, but also form the volute 921 of the cross-flow fan by assembling the second split shell 9211 with the first split shell. This makes the overall structure compact, the space utilization reasonable, improves the space utilization rate, and reduces material costs.

[0083] Please see Figure 11For example, the second split shell 9211 has multiple partitions 9212 on the side facing the outside. These partitions 9212 are arranged sequentially at intervals along the axial direction of the cross-flow fan, that is, sequentially from the left to the right side of the second split shell 9211. Adjacent partitions 9212 cooperate to form a noise reduction chamber. Thus, the second split shell 9211 has multiple noise reduction chambers on the side facing the outside, arranged sequentially from the left to the right side of the second split shell 9211. When sound waves pass through the first sound insulation layer 561 and enter the noise reduction chamber, they undergo multiple reflections and interferences within the noise reduction chamber, further attenuating the energy and thus improving the sound insulation effect.

[0084] Based on the aforementioned embodiments, the sound insulation material includes, for example, a sound insulation film. The sound insulation film is disposed between the main sound insulation panel 5621 and the first sound insulation layer 561. Specifically, the sound insulation film can be bonded to the sides of the main sound insulation panel 5621 and the first sound insulation layer 561 facing each other, or it can be pressed between the main sound insulation panel 5621 and the first sound insulation layer 561, or it can be installed and fixed using pins, screws, or clips. The main sound insulation panel 5621 is a flat plate, which facilitates the covering of the sound insulation film onto the main sound insulation panel 5621, making the installation operation relatively convenient and quick.

[0085] Of course, as some optional solutions, the sound insulation material may also include, for example, sound insulation cotton, which is filled between the first sound insulation layer 561 and the second sound insulation layer 562. When the sound insulation cotton is filled in the noise reduction chamber, the noise reduction chamber forms a composite sound-absorbing structure, which has a better sound-absorbing effect.

[0086] Please see Figures 9 to 12 For example, the first sound insulation layer 561 also includes multiple sound insulation side panels. All of the multiple sound insulation side panels are connected to the central partition 5611. The multiple sound insulation side panels include a first sound insulation side panel 5612, a second sound insulation side panel 5613, and a third sound insulation side panel 5614. The first sound insulation side panel 5612 and the second sound insulation side panel 5613 are spaced apart from each other, and the third sound insulation side panel 5614 is connected between the first sound insulation side panel 5612 and the second sound insulation side panel 5613. The first sound insulation side panel 5612 and the second sound insulation side panel 5613 are located at opposite ends of the indoor heat exchanger 40 and the indoor fan 92, respectively, and are both connected to the second sound insulation layer 562. The third sound insulation side panel 5614 is disposed on the top side of the indoor fan 92 and is connected to the second sound insulation layer 562.

[0087] Please see Figure 11 and Figure 12For example, the air conditioner also includes a connecting pipe fitting. The indoor unit is connected to the outdoor unit via the connecting pipe fitting. Specifically, the compressor 10 or the indoor heat exchanger 40 is connected to the indoor heat exchanger 40 via the connecting pipe fitting. The partition plate 5611 has a pipe passage 5615, through which the connecting pipe fitting passes. Optionally, the connecting pipe fitting may have at least two channels, one channel connecting the compressor 10 and the indoor heat exchanger 40, and the other channel connecting the indoor heat exchanger 40 and the outdoor heat exchanger 20. It should be noted that the pipe passage 5615 can be either a closed hole or an open hole, without limitation, and can be set according to actual needs.

[0088] For example, the air conditioner also includes a resilient buffer 5616. The resilient buffer 5616 is disposed within the pipe hole 5615, and abuts against the wall of the pipe hole 5615 and the outer wall of the connecting pipe fitting. In this way, the resilient buffer 5616 can play a buffering role, absorbing the vibration of the connecting pipe fitting, thereby reducing noise.

[0089] For example, the elastic buffer 5616 includes an elastic sleeve. The elastic sleeve is interference-fitted with the inner wall of the pipe hole 5615, and the outer wall of the connecting pipe fitting is interference-fitted with the inner wall of the elastic sleeve. In this way, the elastic buffer 5616 can prevent noise generated on the outdoor side from leaking outward through the gap between the pipe hole 5615 and the outer wall of the connecting pipe fitting, effectively improving the sound leakage of the pipeline channel.

[0090] For example, the elastic sleeve includes, but is not limited to, a rubber sleeve.

[0091] For example, the conduit hole 5615 is located at the bottom corner of the partition plate 5611. Specifically, the conduit hole 5615 is located at the lower right or lower left corner of the partition plate 5611. In this way, on the one hand, the conduit hole 5615 is far away from the central part of the first sound insulation layer 561, which mainly plays a role in sound insulation, and has little impact on the sound insulation effect of the first sound insulation layer 561, so the first sound insulation layer 561 still has a good sound insulation effect; on the other hand, since the first sound insulation layer 561 is wrapped around the second sound insulation layer 562, when the conduit hole 5615 is located at the corner, it can avoid the second sound insulation layer 562, so there is no need to set a corresponding conduit hole 5615 on the second sound insulation layer 562.

[0092] For example, two supports 51 are provided and spaced apart from each other in the interior cavity. The opposite ends of the indoor heat exchanger 40 are connected to the two supports 51 one-to-one.

[0093] The specific structural form of the support bracket 51 can be flexibly adjusted and set according to actual needs, and there are many forms, as long as it can support the indoor heat exchanger 40. For example, please refer to... Figures 5 to 7In any embodiment, the support 51 can be configured as a grid frame. A grid frame has high structural strength, ensuring stable support for the indoor heat exchanger 40. Furthermore, the large number of mesh openings provides a larger ventilation area, thus increasing the air intake area of ​​the indoor heat exchanger 40. Alternatively, the support 51 can be configured as a frame with a central opening forming a ventilation section. Compared to a grid frame, a frame provides a larger air intake area. To ensure the structural strength of the support 51, it can be made of, but is not limited to, metal or rigid, non-deformable non-metallic materials. The frame can be a closed annular frame, such as a rectangular or pentagonal polygonal frame, or other regular or irregular shapes; it can also be a non-closed annular frame, meaning it has notches, such as a C-shaped frame, a U-shaped frame, or other regular or irregular shapes. Of course, besides the grid frames and frames described in the above embodiments, the support 51 can also be configured as, for example, T-shaped, L-shaped, or other various shapes, without further limitations.

[0094] Please see Figure 7 and Figure 9 In one embodiment, mounting brackets 401 are provided at both ends of the indoor heat exchanger 40, and each mounting bracket 401 is correspondingly mounted on each support 51. The two mounting brackets 401 of the indoor heat exchanger 40 are respectively supported by two supports 51, thereby being stably set inside the outer casing 80.

[0095] To further improve the support stability of the indoor heat exchanger 40, for example, please refer to Figures 5 to 7 The bracket 51 has a support surface 512, which abuts against the bottom surface of the mounting frame 401 and is shaped accordingly. The support surface 512 has a high degree of fit with the bottom surface of the mounting frame 401, providing good support stability for the mounting frame 401. Furthermore, the structure is compact and the overall volume is small.

[0096] It should be noted that the heat exchange section of the indoor heat exchanger 40 can be one fold, two folds, three folds or more.

[0097] Specifically, the shape of the mounting bracket 401 is set according to the number of folds in the heat exchange section of the indoor heat exchanger 40. When the heat exchange section is set to one fold, the mounting bracket 401 is set to a straight shape, and the bottom surface of the mounting bracket 401 is, for example, a flat surface, and the supporting surface 512 is set to a flat surface. When the heat exchange section is set to two folds, the mounting bracket 401 is set to a zigzag shape, and both folds of the heat exchange section are connected to and supported by the mounting bracket 401. The supporting surface 512 is, for example, a flat surface. The support surface 512 can be directly aligned with the portion of the mounting bracket 401 corresponding to the bottom heat exchange section, or it can be configured as a zigzag surface that abuts against all portions of the mounting bracket 401 corresponding to each heat exchange section. When the heat exchange section is configured as a three-fold section, the mounting bracket 401 is correspondingly configured as a zigzag shape, with all three heat exchange sections connected to and supported by the mounting bracket 401. The support surface 512 can be configured as a zigzag surface, and the support surface 512 can abut against the two bottom heat exchange sections of the mounting bracket 401. Optionally, please refer to... Figure 5 or Figure 7 When the bottom surface of the mounting bracket 401 is set to a V-shape, the support surface 512 is set to a V-shape accordingly.

[0098] Of course, as some optional solutions, the shape of the support surface 512 of the bracket 51 and the bottom surface of the mounting bracket 401 does not need to be completely consistent, as long as it satisfies the stable support of the mounting bracket 401, and no further restrictions are imposed here.

[0099] Please see Figures 7 to 9 For example, the two opposite ends of the indoor fan 92 are respectively connected to two mounting brackets 401. The mounting brackets 401 not only support the indoor heat exchanger 40, but also provide stable support for the indoor fan 92.

[0100] In one specific embodiment, the indoor heat exchanger 40 includes multi-fold heat exchange sections, which are sequentially connected and arranged around the outer periphery of the indoor fan 92, with adjacent heat exchange sections arranged at an angle. Thus, with the outer casing 80 having the same height, by configuring the indoor heat exchanger 40 as a multi-fold heat exchange section with adjacent heat exchange sections arranged at an angle, the air inlet area can be increased, thereby improving the heat exchange effect.

[0101] Based on the aforementioned embodiments, the air conditioner is, for example, a window air conditioner. The heat exchange section of the window air conditioner is configured with at least three folds. Specifically, the heat exchange section of the window air conditioner includes, but is not limited to, three-fold, four-fold, or even five-fold folds. Thus, compared to the straight-vent or two-fold forms in related technologies, the heat exchange efficiency of the indoor heat exchanger 40 can be greatly increased due to the increased number of folds in the heat exchange section.

[0102] In one embodiment, the outer casing 80 includes a front panel, which is also the front of the main casing 82. A first air inlet 801 is disposed on the front panel. The front panel also has an air outlet located above the first air inlet 801. After heat exchange, the air is blown into the room through the air outlet by the indoor fan 92. That is, the indoor unit of the air conditioner in this embodiment adopts a front air inlet and front air outlet structure. When the indoor fan 92 is working, it can drive indoor air from the first air inlet 801 into the outer casing 80 from the front. The indoor air entering the outer casing 80 can be directly blown towards the indoor heat exchanger 40 and exchange heat with the indoor heat exchanger 40, thus achieving front air inlet.

[0103] For example, the housing 80 includes a chassis 81. A water storage tank 811 is provided on the chassis 81 at a location corresponding to the outdoor cavity, and the water storage tank 811 is used to store condensate. That is, the water storage tank 811 is located in the outdoor cavity, so that the stored condensate can be used by the outdoor fan 70, which is also located in the outdoor cavity. The housing 80 also includes a main housing 82. The main housing 82 is connected to the chassis 81 and cooperates to form a receiving space. To clearly show the installation position of the bracket 51 within the housing 80, as shown... Figure 7 The main housing 82 of the outer shell 80 is hidden, that is, only the chassis 81 of the outer shell 80 is retained, and each bracket 51 has a gap with the corresponding side of the chassis 81.

[0104] Please see Figures 5 to 8 For example, the air conditioner also includes a collection tray 83. The collection tray 83 is disposed inside the indoor cavity and located below the indoor cavity. The bracket 51 is connected to the collection tray 83, such that the bracket 51 is indirectly connected to the bottom wall of the housing 80.

[0105] For example, the bracket 51 and the collection tray 83 may be an integrated structure. Specifically, the bracket 51 and the collection tray 83 may be connected by welding, sheet metal molding, or die casting, among other methods. In this way, the bracket 51 is stably mounted on the collection tray 83 and has good waterproof performance. Of course, as some optional solutions, the bracket 51 and the collection tray 83 may also be assembled together using screws, pins, etc.

[0106] For example, the bottom of the first sound insulation layer 561 is connected to the side wall of the collection tray 83 near the outside, that is, it is indirectly connected to the bottom wall of the outer casing 80.

[0107] For example, both the indoor heat exchanger 40 and the indoor fan 92 are located above the collection tray 83 and are positioned correspondingly to the collection tray 83. This corresponding positioning of the indoor heat exchanger 40 and the indoor fan 92 to the collection tray 83 can also be understood as the projections of the indoor heat exchanger 40 and the indoor fan 92 in the vertical direction both falling within the collection tray 83. In this way, the condensate generated by the indoor heat exchanger 40 during operation will fall into and be collected by the collection tray 83, thus effectively collecting the condensate.

[0108] For example, the collection tray 83 is provided with a discharge section. The discharge section is used to discharge condensate in the collection tray 83 into the water storage tank 811. The discharge section extends through the partition 5611 into the external cavity, and is used to discharge condensate in the collection tray 83 into the water storage tank 811. Specifically, the discharge section is provided with a discharge channel 85, through which the condensate in the collection tray 83 is discharged into the water storage tank 811. The discharge channel 85 specifically includes, for example, a discharge trough 841, that is, the cross-sectional profile of the discharge channel 85 along its water flow direction is not closed, and the top of the discharge channel 85 is open.

[0109] Optionally, a clearance gap is formed between the bottom of the partition 5611 corresponding to the discharge section and the bottom wall of the outer casing 80, through which the discharge section extends from the interior cavity to the exterior cavity. Furthermore, in order to reduce noise, the bottom of the partition 5611 overlaps with the discharge section, thereby reducing the gap between the partition 5611 and the discharge section.

[0110] Please see Figure 3 and Figure 8 Specifically, the outdoor fan 70 includes a drive motor 72, fan blades 71, and a water-spraying ring 73. The drive motor 72 is connected to the fan blades 71 and drives the fan blades 71 to rotate. The water-spraying ring 73 is arranged circumferentially around the fan blades 71, and the bottom of the water-spraying ring 73 extends into the water storage tank 811. In this way, the condensate collected by the collection tray 83 can be discharged into the water storage tank 811 through the discharge section, and then utilized by the water-spraying ring 73 of the outdoor fan 70. After the water-spraying ring 73 agitates the condensate, the condensate is atomized and can reduce the temperature of the outdoor heat exchanger 20.

[0111] Specifically, the outdoor fan 70 also includes a support base. The support base is connected to the chassis 81 and is also connected to the drive motor 72, serving to stably support the drive motor 72.

[0112] Please see Figure 6 , Figure 7 , Figure 10 and Figure 11For example, the discharge section includes a discharge housing 84 connected to a collection tray 83, specifically as an integral structure formed by injection molding. The discharge housing 84 has a discharge groove 841, one end of which communicates with the collection tray 83, and the other end extends to a water storage tank 811. Thus, the condensate collected in the collection tray 83 can be discharged into the water storage tank 811 through the discharge groove 841. To facilitate the smooth discharge of condensate into the water storage tank 811, the bottom wall height of the discharge groove 841 decreases along the discharge direction.

[0113] For example, the collection tray 83 and the water storage tank 811 are arranged along the front-to-back direction of the air conditioner. Taking the normal installation and use of the air conditioner as a reference, the bottom wall of the chassis 81 corresponding to the collection tray 83 is higher than the bottom wall of the water storage tank 811, which facilitates the collection of condensate in the chassis 81 into the water storage tank 811, thus ensuring its full utilization. Alternatively, as an option, a water-blocking structure can be provided between the bottom wall of the chassis 81 corresponding to the collection tray 83 and the bottom wall of the water storage tank 811. This water-blocking structure can be, for example, ribs protruding from the bottom wall of the chassis 81. The water-blocking structure acts as a barrier, preventing condensate in the water storage tank 811 from flowing out to other parts of the chassis 81.

[0114] Please see Figure 7 For example, the side wall of the chassis 81 is provided with an overflow port 812 corresponding to the water storage tank 811. When the condensate level in the water storage tank 811 is higher than the overflow port 812, it will be discharged outward in a timely manner through the overflow port 812 and the drain pipe connected to the overflow port 812, thereby maintaining the liquid level in the water storage tank 811 within the normal range and preventing leakage defects caused by condensate overflowing from other areas.

[0115] For example, a gap is provided between the collection tray 83 and the water storage tank 811 in the front-to-back direction. The compressor 10 is arranged in the gap. The discharge housing 84 extends through the gap to the water storage tank 811. In order to avoid various components such as the compressor 10 installed in the gap, the discharge housing 84 is specifically provided, for example, on the side of the chassis 81.

[0116] The condensate in the collection tray 83 can be discharged into the water storage tank 811 through the discharge section. If the outlet of the discharge section is not soundproofed, the noise generated by the compressor 10 and the indoor fan 92 during operation will enter the room through the discharge section. Therefore, in order to prevent the noise generated by the compressor 10 and the outdoor fan 70 during operation from entering the room through the discharge section, please refer to... Figure 6 or Figures 14 to 19For example, the discharge section also includes a resistive anechoic chamber 88. The resistive anechoic chamber 88 is connected to the discharge channel 85. In use, on the one hand, the collection tray 83 collects the condensate generated during operation inside the chamber and discharges the collected condensate through the discharge section and discharge channel 85 into the water storage tank 811 for use outside the chamber; on the other hand, the noise generated during operation outside the chamber can be blocked and reduced by the first sound insulation layer 561; and since the discharge section also includes a resistive anechoic chamber 88, which is connected to the discharge channel 85, the noise generated during operation outside the chamber can enter the resistive anechoic chamber 88 during the backflow of noise from the discharge channel 85 to the indoor side, thereby being silenced and reduced by the resistive anechoic chamber 88, further improving the noise reduction and sound insulation effect.

[0117] The reactive anechoic chamber 88 can achieve noise reduction by utilizing the expansion or contraction of the pipe cross-section or by connecting a resonant cavity, taking advantage of the reflection, interference, or resonance phenomena of sound waves. In other words, when sound waves pass through the reactive anechoic chamber 88, the change in impedance causes noise of certain frequencies or frequency bands to be reflected, interfered with, or resonated within the reactive anechoic chamber 88, consuming the energy of the sound and thus reducing the noise after passing through the reactive anechoic chamber 88, thereby achieving the purpose of noise reduction.

[0118] The resistive anechoic chamber 88 can be a resonant anechoic chamber, an expansion anechoic chamber, or an impedance composite anechoic chamber, etc. The specific type can be flexibly adjusted and set according to actual needs, and is not limited here.

[0119] Each of the 88 types of resistance anechoic chambers in the emission section is selected independently according to actual needs. Each type can be selected from any one of the resonant anechoic chamber, expansion anechoic chamber, and impedance composite anechoic chamber. They can be completely the same or different from each other, and there is no limitation here.

[0120] For example, the number of resistive anechoic chambers 88 is not limited to one, but may be at least two, specifically two, three, four or more. The specific number is not limited in this embodiment and can be flexibly adjusted and set according to actual needs, as long as the final noise reduction effect meets the requirements. It is understood that the more resistive anechoic chambers 88 there are, the better the sound insulation and noise reduction effect will be, but it will also make the structure of the exhaust section more complex and lead to a larger space occupation to a certain extent.

[0121] In one specific embodiment, please refer to Figure 6 or Figures 14 to 19For example, there are two resistive anechoic chambers 88, namely a first resistive anechoic chamber 86 and a second resistive anechoic chamber 87. By adopting a bipolar anechoic design at the discharge section, sound leakage at the discharge section can be effectively reduced at a lower cost or without adding extra materials. Compared with the labyrinthine anechoic structure in related technologies, the water path is shorter, the risk of blockage is lower, and the space occupied is smaller, saving installation space. In addition, the structure is simple and easy to process and manufacture.

[0122] In one specific embodiment, please refer to Figure 6 The first resistive anechoic chamber 86 is configured as a resonant anechoic chamber, and has a first connecting port 861. The first resistive anechoic chamber 86 is located on one side of the exhaust channel 85, and the first connecting port 861 is connected to the exhaust channel 85. That is, the first resistive anechoic chamber 86 is connected to the exhaust channel 85. The second resistive anechoic chamber 87 is configured as an expansion anechoic chamber, and has a second connecting port 871 and a third connecting port 872. The second resistive anechoic chamber 87 is arranged in series in the exhaust channel 85.

[0123] More specifically, the collection tray 83 is provided with a discharge port 831, which is formed, for example, on the side wall of the collection tray 83 near the outdoor area. The discharge channel 85 includes a first discharge section 851 and a second discharge section 852. One end of the first discharge section 851 is connected to the discharge port 831, the other end of the first discharge section 851 is connected to a second connecting port 871, and a third connecting port 872 is connected to the second discharge section 852, so that the second resistive anechoic chamber 87 is connected in series to the discharge channel 85. The condensate from the collection tray 83 is discharged outward sequentially through the discharge port 831, the first discharge section 851, the second resistive anechoic chamber 87, and the second discharge section 852. Since the first resistive anechoic chamber 86 is connected to the discharge channel 85, the first resistive structure can be set at any position in the discharge channel 85, for example, on either side of the first discharge section 851 or on either side of the second discharge section 852.

[0124] In this embodiment, the first resistive anechoic chamber 86 is connected to the first discharge section 851, meaning the first connecting port 861 is connected to one side of the first discharge section 851. Furthermore, the first connecting port 861 and the second connecting port 871 are arranged opposite each other. Thus, outdoor noise enters the second resistive anechoic chamber 87 along the second discharge section 852 and the third connecting port 872. After being anechoic in the second resistive anechoic chamber 87, a portion of the noise is discharged through the second connecting port 871, while most of the discharged noise enters the first resistive anechoic chamber 86, which is directly opposite it, and is then anechoic, resulting in a good noise reduction effect. Furthermore, by using a dual-stage anechoic chamber to block noise at the discharge port 831, the noise blocking performance at the discharge port 831 can be effectively improved without affecting the smooth discharge of condensate, solving the sound leakage problem at the discharge port 831, while also saving installation space.

[0125] In another specific embodiment, please refer to Figures 14 to 19 Compared to Figure 6 The difference in the structure shown is that the second resistive anechoic chamber 87 is not configured as an expansion anechoic chamber, but rather as, for example, a resonant anechoic chamber. Specifically, the second resistive anechoic chamber 87 has a fourth connecting port 873, and the second resistive anechoic chamber 87 is located on one side of the exhaust channel 85, with the fourth connecting port 873 communicating with the exhaust channel 85. That is, the second resistive anechoic chamber 87 is connected to the exhaust channel 85.

[0126] Please continue reading. Figure 17 and Figure 19 Based on the aforementioned embodiment, the first resistive anechoic chamber 86 and the second resistive anechoic chamber 87 are respectively arranged on opposite sides of the discharge channel 85. Furthermore, the first connecting port 861 and the fourth connecting port 873 are arranged, for example, facing each other. Thus, as outdoor noise enters the indoor side along the discharge channel 85, a portion of the noise enters the first resistive anechoic chamber 86 through the first connecting port 861 and is anechoic, while another portion enters the second resistive anechoic chamber 87 through the second connecting port 871 and is anechoic. Very little noise enters the indoor cavity through the discharge port 831. Furthermore, by using a two-stage anechoic chamber to block noise at the discharge port 831, the noise blocking performance at the discharge port 831 can be effectively improved without affecting the smooth discharge of condensate, solving the sound leakage problem at the discharge port 831, while also saving installation space.

[0127] Please continue reading. Figure 17 and Figure 19Based on the aforementioned embodiments, the flow cross-sectional area of ​​the first discharge section 851 is smaller than that of the second discharge section 852. This facilitates the discharge of condensate from the collection tray 83 from the first discharge section 851 to the second discharge section 852, preventing blockages and ensuring smooth discharge of condensate into the water storage tank 811. Furthermore, it reduces the amount of outdoor noise entering the first discharge section 851.

[0128] Please continue reading. Figure 17 and Figure 19 Based on the aforementioned embodiment, the inner wall of the second discharge section 852 is provided with a sound insulation part 853. The sound insulation part 853 includes, but is not limited to, a sound insulation panel, a protrusion, etc. The sound insulation part 853 serves to block noise, and the number of sound insulation parts 853 may be one or more. Multiple sound insulation parts 853 are arranged sequentially along the water flow direction. The sound insulation part 853 can change the flow direction of condensate water, and also change the sound propagation path. By repeatedly adjusting the sound propagation path, an effective sound absorption and insulation effect can be achieved.

[0129] The first resistive anechoic chamber 86 and the second resistive anechoic chamber 87 are both located between the discharge port 831 and the second discharge section 852. The walls of the first resistive anechoic chamber 86 and the second resistive anechoic chamber 87 are spaced apart to form the first discharge section 851. Optionally, the first resistive anechoic chamber 86 and / or the second resistive anechoic chamber 87 can block the opening of the second discharge section 852 near the first discharge section 851, thereby helping to reduce outdoor noise entering the first discharge section 851.

[0130] For example, in this embodiment, the silencing frequencies of the two reactive silencing chambers 88 can be completely consistent or inconsistent. When the silencing frequencies of the two reactive silencing chambers 88 are inconsistent, their silencing frequencies may partially overlap or not overlap at all. After the silencing frequencies of the two reactive silencing chambers 88 are superimposed, the silencing frequency range of the exhaust section is wider, which can improve the silencing effect.

[0131] It should be noted that for each reactive anechoic chamber 88, the silencing frequency can usually be achieved by adjusting the relevant dimensional parameters of the reactive anechoic chamber 88 itself. For example, by adjusting at least one design parameter among the volume of the reactive anechoic chamber 88, the depth of the connection port of the reactive anechoic chamber 88, and the cross-sectional area of ​​the connection port perpendicular to the noise inlet / outlet direction, the silencing frequency and range of the reactive anechoic chamber 88 can be adjusted accordingly. The depth of the connection port refers to the length of the overlapping portion of the two opposite sidewalls forming the connection port perpendicular to the noise inlet / outlet direction.

[0132] Please refer to the following: Figure 17 and Figure 19For the first resistive anechoic chamber 86, the depth of the first connecting opening 861 is d1, the width of the first connecting opening 861 is M1, the height of the first connecting opening 861 is H1, and the cross-sectional area S1 of the first connecting opening 861 is the product of the width M1 and the height H1. The depth d1 of the first connecting opening 861 refers to the length of the overlapping portion of the two opposite sidewalls forming the first connecting opening 861 perpendicular to the noise inlet / outlet direction. The width W1 of the first connecting opening 861 refers to the distance between the two opposite sidewalls of the first connecting opening 861, and the height H1 of the first connecting opening 861 refers to the height of the two opposite sides protruding from the bottom wall of the first resistive anechoic chamber 86. By adjusting at least one of the design parameters of the volume, depth d1, and cross-sectional area S1 of the first resistive anechoic chamber 86, the anechoic frequency and width of the first resistive anechoic chamber 86 can be adjusted.

[0133] For the second resistive anechoic chamber 87, the depth of the fourth connecting port 873 is d2, the width of the fourth connecting port 873 is M2, the height of the fourth connecting port 873 is H2, and the cross-sectional area S2 of the fourth connecting port 873 is the product of the width M2 and the height H2. Here, the depth d2 of the fourth connecting port 873 refers to the length of the overlapping portion of the two opposite sidewalls forming the fourth connecting port 873 perpendicular to the noise inlet / outlet direction; the width W2 of the fourth connecting port 873 refers to the distance between the two opposite sidewalls of the fourth connecting port 873; and the height H2 of the fourth connecting port 873 refers to the height of the two opposite sides protruding from the bottom wall of the second resistive anechoic chamber 87. By adjusting at least one of the design parameters of the volume, depth d2, and cross-sectional area S2 of the second resistive anechoic chamber 87, the anechoic frequency and width of the second resistive anechoic chamber 87 can be adjusted.

[0134] Please see Figure 6 and Figure 10 Or refer to Figures 14 to 16 For example, the discharge section also includes a soundproof cover 5617. The soundproof cover 5617 is disposed on the top of the discharge housing 84, and the soundproof cover 5617 cooperates with the discharge housing 84 to form a discharge channel 85 and a resistive anechoic chamber 88.

[0135] Optionally, the soundproof cover 5617 may be connected to, for example, the first soundproof layer 561, specifically to the partition 5611. Optionally, the soundproof cover 5617 and the first soundproof layer 561 may be an integral structure. This facilitates processing and improves assembly efficiency.

[0136] Of course, the soundproof cover 5617 and the first soundproof layer 561 can also be separate structures, installed independently, without much restriction here.

[0137] For example, the pipe hole 5615 is provided at one corner of the bottom of the partition plate 5611, and the discharge part is located at the other corner of the bottom of the partition plate 5611.
