Description

Technical Field

[0001] This application relates to the field of air treatment technology, and in particular to an air conditioner. Background Technology

[0002] In the related technology, window air conditioners (hereinafter referred to as window units) typically employ a method of air intake from the front of the indoor heat exchanger and air exhaust from the top of the front during the indoor cooling cycle. Alternatively, they may employ a method of air intake from the front of the indoor heat exchanger and air exhaust from the side, all of which can reduce indoor temperature. However, the heat exchange efficiency of the indoor heat exchanger in these technologies is relatively low, thus reducing the energy efficiency of the air conditioner. Utility Model Content

[0003] Therefore, it is necessary to overcome the shortcomings of existing technologies and provide an air conditioner that can effectively improve the heat exchange efficiency of the indoor heat exchanger, thereby improving energy efficiency.

[0004] This application provides an air conditioner, including:

[0005] Indoor heat exchanger;

[0006] The outer casing has a first air inlet, and the indoor heat exchanger is disposed inside the outer casing;

[0007] The brackets are configured as two and spaced apart within the outer casing. The opposite ends of the indoor heat exchanger are connected to the two brackets respectively. The brackets are spaced apart from the inner wall of the outer casing to form a first ventilation gap. Each bracket has a ventilation section that penetrates the bracket along the arrangement direction of the two brackets. The arrangement direction of the two brackets forms an angle with the air inlet direction of the first air inlet.

[0008] An indoor fan is disposed inside the outer casing and is located on the side of the indoor heat exchanger opposite to the first air inlet. The indoor fan is used to drive indoor air from the first air inlet into the outer casing and through the indoor heat exchanger by rotation, so that the indoor heat exchanger exchanges heat with the indoor air.

[0009] In one embodiment, the support is configured as a grid frame, and the ventilation section is a mesh provided on the grid frame; or, the support is a frame, and the ventilation section is formed by hollowing out the middle of the frame.

[0011] In one embodiment, the indoor heat exchanger includes multiple heat exchange sections, which are sequentially connected and arranged around the outer periphery of the indoor fan, with adjacent heat exchange sections arranged at an angle.

[0012] In one embodiment, the air conditioner is a window air conditioner, and the heat exchange section has at least three folds.

[0013] In one embodiment, the housing includes:

[0014] The front panel has a first air inlet disposed thereon, and the front panel also has an air outlet located above the first air inlet; and

[0015] The side panels are two in number and are arranged at intervals relative to each other. Both side panels are connected to the front panel. The two brackets are located on opposite sides inside the housing. Each bracket is arranged at intervals with each side panel and cooperates to form the first ventilation interval.

[0016] In one embodiment, the air conditioner further includes:

[0017] A collection tray is disposed inside the outer casing. The bracket is connected to the collection tray. The indoor heat exchanger and the indoor fan are both located above the collection tray and are positioned corresponding to the location of the collection tray.

[0018] In one embodiment, the support and the collection tray are an integrated structure; and / or, the indoor heat exchanger and the bottom wall of the collection tray are spaced apart to form a second ventilation interval.

[0019] In one embodiment, the housing includes:

[0020] The chassis is provided with a water storage tank, the collection tray is located inside the chassis, and the collection tray is provided with a discharge section for discharging condensate in the collection tray into the water storage tank.

[0021] The air conditioner also includes:

[0022] An outdoor heat exchanger is disposed within the outer casing;

[0023] An outdoor fan is disposed within the housing. The housing has a second air inlet. The outdoor fan draws outdoor air through the second air inlet into the housing and passes it through the outdoor heat exchanger, allowing heat exchange between the outdoor heat exchanger and the outdoor air. The outdoor fan includes:

[0024] Drive motor; and

[0025] Fan blades, the drive motor is connected to the fan blades, and the drive motor is used to drive the fan blades to rotate; and

[0028] In the aforementioned air conditioner, when the indoor fan is operating, it draws indoor air into the outer casing through the first air inlet. A portion of this air is directly blown onto the indoor heat exchanger for heat exchange, while another portion flows through the ventilation section at the first ventilation interval and is then blown onto the indoor heat exchanger. Therefore, the indoor air entering the outer casing can be blown onto the indoor heat exchanger from multiple directions, increasing the air inlet area and thus improving its ventilation volume. This, in turn, enhances the heat exchange efficiency of the indoor heat exchanger, thereby improving the air conditioner's energy efficiency. Attached Figure Description

Detailed Implementation

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The first throttling device is, for example, an expansion valve, which 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] An air conditioner consists of an indoor unit and an outdoor unit, which can be configured as an integrated unit or a split unit.

[0057] 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, the air conditioner in this embodiment will be described using an integrated unit as a specific example.

[0058] The complete unit can be, for example, a window unit, a portable unit, a rooftop unit, or a kitchen air conditioner.

[0059] Please see Figure 16 The 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 air inside the indoor unit, and the outdoor heat exchanger 20 exchanges heat with the air inside the outdoor unit, thereby fulfilling the air conditioner's cooling or heating requirements.

[0060] The indoor unit also includes an indoor fan, which is located near the return air vent or air outlet of the indoor heat exchanger. It is used to deliver the heat-exchanged air into the room. The indoor fan has multiple speed settings to change the airflow speed at the air outlet.

[0061] 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.

[0062] The outdoor unit also includes an outdoor fan, which is located on one side of the outdoor heat exchanger to deliver outdoor air to the heat exchanger for heat exchange. In the embodiments 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.

[0063] As mentioned in the background art, the indoor heat exchanger in the related technology has a low heat exchange efficiency, which leads to a decrease in the energy efficiency of the air conditioner. The reason for this problem is that in the window air conditioner in the related technology, the air intake method is limited to the front of the indoor heat exchanger. The sides of the indoor heat exchanger cannot be aired in, so the air intake area is relatively small, resulting in a small heat exchange area, which reduces the heat exchange efficiency and thus reduces the energy efficiency of the window air conditioner.

[0064] Based on the above reasons, this application provides an air conditioner that can effectively improve the heat exchange efficiency of the indoor heat exchanger, thereby improving energy efficiency.

[0065] The following is for reference. Figures 1-16 This application describes an air conditioner according to an embodiment of the present application.

[0066] See Figures 1 to 3 An air conditioner provided in one embodiment of this application includes an indoor heat exchanger 40 and an indoor fan 92.

[0067] For example, the air conditioner also includes a housing 80. The housing 80 has a first air inlet 801. The first air inlet 801 includes, but is not limited to, multiple air inlets. An indoor heat exchanger 40 is disposed within the housing 80. An indoor fan 92 is disposed within the housing 80, and 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 generates negative pressure by rotating, driving indoor air from the first air inlet 801 into the housing 80 and through the indoor heat exchanger 40, so that the indoor heat exchanger 40 exchanges heat with the indoor air.

[0068] Please see Figures 4 to 6 For example, the air conditioner also includes brackets 51. Two brackets 51 are provided and spaced apart from each other within the housing 80. The opposite ends of the indoor heat exchanger 40 are connected to the two brackets 51 respectively. The brackets 51 are spaced apart from the inner wall of the housing 80 to form a first ventilation gap 52; that is, there is a gap between the brackets 51 and the inner wall of the housing 80. In other words, there is a gap between the projection of the brackets 51 along the direction perpendicular to the bottom wall of the housing 80 and the side of the housing 80.

[0069] For example, the housing 80 includes a chassis 81. The chassis 81 is provided with a water storage tank 811 for storing condensate. The housing 80 also includes a main housing 82. The main housing 82 is connected to and cooperates with the chassis 81 to form a receiving space. To clearly show the installation position of the bracket 51 within the housing 80, as shown... Figure 6 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.

[0070] Please refer to the following: Figures 4 to 6The bracket 51 is provided with a ventilation section 511. The ventilation section 511 extends through the bracket 51 along the arrangement direction of the two brackets 51. The arrangement direction of the two brackets 51 is set at an angle to the air inlet direction of the first air inlet 801. The first ventilation interval 52 is connected to the area between the two brackets 51 through the ventilation section 511. Under the negative pressure of the indoor fan 92, the indoor air flowing to the first ventilation interval 52 can pass through the ventilation section 511 and enter the area between the two brackets 51, thereby achieving heat exchange with the indoor heat exchanger 40.

[0071] Thus, when the indoor fan 92 is working, it can draw indoor air into the outer casing 80 through the first air inlet 801. A portion of the indoor air entering the outer casing 80 can be directly blown towards the indoor heat exchanger 40 and exchange heat with it. Another portion flows to the first ventilation interval 52, passes through the ventilation section 511, and is then blown towards the indoor heat exchanger 40. Therefore, the indoor air entering the outer casing 80 can be blown towards the indoor heat exchanger 40 from multiple different directions, increasing the air inlet area of ​​the indoor heat exchanger 40, which in turn increases the ventilation volume of the indoor heat exchanger 40. This improves the heat exchange efficiency of the indoor heat exchanger 40, thereby enhancing the energy efficiency of the air conditioner.

[0072] The specific structural form of the 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 and has a ventilation section 511.

[0073] For example, please see Figures 6 to 9 In any one of the designs, the support 51 can be configured as a grid frame, and the ventilation section 511 is a mesh on the grid frame. The grid frame structure has high strength, which can ensure stable support for the indoor heat exchanger 40, and the large number of mesh openings makes the ventilation area of ​​the ventilation section 511 larger, thereby increasing the air intake area of ​​the indoor heat exchanger 40.

[0074] For example, the bracket 51 can also be configured as a frame, with a hollowed-out center forming a ventilation section 511. Compared to a grid frame, a frame can create a larger air intake area. To ensure the structural strength of the bracket 51, the bracket 51 may be made of metal or a rigid and non-deformable non-metallic material, including but not limited to metal. The frame can be a closed annular frame, such as a rectangular frame, a pentagonal frame, or other polygonal frames or other regular and irregular shapes; the frame can also be a non-closed annular frame, which can be understood as having a notch, specifically such as a C-shaped frame, a U-shaped frame, or other regular and irregular shapes.

[0075] Of course, in addition to the grid frame and frame in the above embodiments, the bracket 51 can also be configured as, for example, T-shaped, L-shaped or other various shapes, without much limitation here.

[0076] Please see Figures 8 to 10 and Figure 12 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.

[0077] To further improve the support stability of the indoor heat exchanger 40, for example, please refer to Figure 6 and Figure 8 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.

[0078] 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.

[0079] 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 6 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] The more folds in the heat exchange section, the more space can be utilized within the outer shell 80, resulting in a larger air intake area when fully expanded. However, as the number of folds increases—for example, to three, four, or five folds—the bottom heat exchange section of the indoor heat exchanger 40 (the section closest to the bottom wall of the outer shell 80) suffers from poor air intake conditions, leading to a smaller air volume and consequently reducing the heat exchange efficiency. In this embodiment, the ventilation section 511 on the bracket 51 increases the ventilation volume of the bottom heat exchange section of the indoor heat exchanger 40, effectively compensating for the insufficient total circulating air volume of the indoor heat exchanger 40 and thus improving its heat exchange efficiency.

[0084] 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.

[0085] 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.

[0086] In one embodiment, the outer casing 80 further includes side panels. These side panels are also the sides of the main casing 82. There are two side panels that are spaced apart from each other, and both side panels are connected to the front panel. Two brackets 51 are located on opposite sides inside the outer casing 80, and each bracket 51 is spaced apart from each side panel and cooperates to form a first ventilation gap 52.

[0087] When the indoor fan 92 is working, it draws indoor air into the outer casing 80 from the front through the first air inlet 801. A portion of the indoor air entering the casing 80 can be directly blown towards the indoor heat exchanger 40 and exchange heat with it, thus achieving front air intake. The other portion flows to the first ventilation interval 52, passes through the ventilation section 511, and is blown towards the indoor heat exchanger 40, thus achieving air intake from both sides. In other words, when the indoor heat exchanger 40 is working, it can achieve simultaneous air intake from the front and both sides, resulting in a large air intake area and a large circulating air volume, thereby achieving high heat exchange efficiency and improving the energy efficiency of the air conditioner.

[0088] Please see Figure 4 , Figure 6 , Figure 9 and Figure 12 In one embodiment, the heat exchange section is specifically a three-fold section, comprising a first fold heat exchange section 41, a second fold heat exchange section 42, and a third fold heat exchange section 43 connected sequentially. The first fold heat exchange section 41 and the second fold heat exchange section 42 are arranged at an angle, and the second fold heat exchange section 42 and the third fold heat exchange section 43 are also arranged at an angle. The first fold heat exchange section 41 and the second fold heat exchange section 42 are both located below the third fold heat exchange section 43. The opposite ends of the first fold heat exchange section 41, the second fold heat exchange section 42, and the third fold heat exchange section 43 are respectively connected to two mounting brackets 401. The shape of the mounting bracket 401 is adapted to the end shape of the three-fold heat exchange section, that is, it is correspondingly set as a three-fold structure, thereby realizing the connection with the end of the three-fold heat exchange section. The parts on the mounting bracket 401 corresponding to the positions of the first fold heat exchange section 41 and the second fold heat exchange section 42 are connected to the bracket 51. Specifically, the parts on the mounting bracket 401 corresponding to the positions of the first heat exchange section 41 and the second heat exchange section 42 are adapted to the shape of the support surface 512 and are all set in a V-shape, so as to be stably installed on the support surface 512.

[0089] Please see Figure 6 and Figure 10 For example, the air conditioner also includes a collection tray 83. The collection tray 83 is disposed within the outer casing 80, and the bracket 51 is connected to the collection tray 83. The indoor heat exchanger 40 and the indoor fan 92 are both located above the collection tray 83 and are positioned correspondingly to the collection tray 83. This correspondence between the indoor heat exchanger 40 and the indoor fan 92 and the collection tray 83 can also be understood as the vertical projections of the indoor heat exchanger 40 and the indoor fan 92 being located within the collection tray 83. In this way, the condensate generated by the indoor heat exchanger 40 during operation will fall into the collection tray 83 and be collected, thus effectively collecting the condensate.

[0090] 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.

[0091] Please see Figure 5 , Figure 8 and Figure 10 For example, the bottom wall of the indoor heat exchanger 40 and the collection tray 83 are spaced apart to form a second ventilation gap 53. This increases the bottom ventilation volume of the indoor heat exchanger 40, thereby increasing heat exchange efficiency. The vertical dimension of the second ventilation gap 53 (i.e., the distance between the bottom walls of the indoor heat exchanger 40 and the collection tray 83) can be flexibly adjusted and set according to actual needs. When the vertical dimension of the second ventilation gap 53 is small, the bottom ventilation of the indoor heat exchanger 40 will be obstructed, resulting in reduced heat exchange efficiency; when the vertical dimension of the second ventilation gap 53 is large, the ventilation area of ​​the indoor heat exchanger 40 will be small, also resulting in reduced heat exchange efficiency. Therefore, the vertical dimension of the second ventilation gap 53 is set, for example, from 5mm to 20mm, specifically 5mm, 8mm, 10mm, 15mm, or 20mm, etc.

[0092] Of course, it should be noted that the vertical dimension of the second ventilation interval 53 can also be set to any value less than 5mm and greater than 20mm, all of which are within the protection scope of this application.

[0093] For example, the air conditioner also includes an outdoor heat exchanger 20 and an outdoor fan 70. Both the outdoor heat exchanger 20 and the outdoor fan 70 are housed within the casing 80.

[0094] The outer casing 80 is provided with a second air inlet 802. The second air inlet 802 includes, but is not limited to, various forms such as air inlet holes. The outdoor fan 70 is used to drive outdoor air into the outer casing 80 through the second air inlet 802 and through the outdoor heat exchanger 20, so that the outdoor heat exchanger 20 exchanges heat with the outdoor air.

[0095] For example, the collection tray 83 is provided with a discharge section. The discharge section is used to discharge the condensate in the collection tray 83 to the water storage tank 811.

[0096] Please see Figure 3 and Figure 11Specifically, 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.

[0097] 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.

[0098] Please see Figure 6 , Figure 7 and Figure 10 For example, the discharge section includes a discharge housing 84, which has a discharge trough 841. One end of the discharge trough 841 communicates with a 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 trough 841. To facilitate the smooth discharge of condensate into the water storage tank 811, the bottom wall height of the discharge trough 841 decreases along the discharge direction.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] Please see Figure 5 , Figures 12 to 15 For example, the air conditioner also includes a flow guide 55. The flow guide 55 is disposed between the bottom of the first heat exchange section 41 and the bottom of the second heat exchange section 42, and the bottoms of both the first heat exchange section 41 and the second heat exchange section 42 abut against the flow guide 55. The bottoms of the first heat exchange section 41, the second heat exchange section 42, and the flow guide 55 are all suspended relative to the bottom wall of the outer casing 80. It should be noted that the bottoms of the first heat exchange section 41 and the second heat exchange section 42 refer to the relatively lower parts of the first heat exchange section 41 and the second heat exchange section 42, with reference to the normal installation and use of the air conditioner, that is, the parts close to the bottom wall of the outer casing 80. Specifically, the bottom of the first heat exchange section 41 and the bottom of the second heat exchange section 42 can be the two adjacent sides of the first heat exchange section 41 and the second heat exchange section 42, or they can be the lower part of the first heat exchange section 41 and the second heat exchange section 42 on the side away from each other.

[0103] Because the bottom of the first heat exchange section 41 is relatively close to the bottom wall of the outer shell 80, that is, the bottom of the first heat exchange section 41 is at a lower position in the vertical direction, a larger amount of condensate will accumulate. Similarly, the bottom of the second heat exchange section 42 is relatively close to the bottom wall of the outer shell 80, that is, the bottom of the second heat exchange section 42 is at a lower position in the vertical direction, resulting in a larger amount of condensate accumulating. In this application, since the bottom of the first heat exchange section 41 and the bottom of the second heat exchange section 42, as well as the guide element 55, are suspended relative to the bottom wall of the outer casing 80, a ventilation gap is formed. When the indoor fan 92 is working, it can drive indoor air from the first air inlet 801 into the outer casing 80 and blow it directly to the indoor heat exchanger 40 to exchange heat with the indoor heat exchanger 40. It can also pass through the ventilation gap between the bottom of the first heat exchange section 41 and the bottom of the second heat exchange section 42, the guide element 55 and the bottom wall of the outer casing 80, and exchange heat with the first heat exchange section 41 and the second heat exchange section 42. Furthermore, the condensate generated during the operation of the first heat exchange section 41 and the second heat exchange section 42 flows along their respective surfaces to the bottom and is promptly guided to the guide member 55. This means the guide member 55 allows the condensate collected at the bottom of the first heat exchange section 41 and the second heat exchange section 42 to be promptly removed, thereby improving the heat exchange efficiency of the indoor heat exchanger 40 and preventing excessive condensate buildup at the bottom of the indoor heat exchanger 40 from affecting the heat exchange effect. Once a certain amount of condensate is collected on the guide member 55, it can fall downwards under gravity. Therefore, the bottom of the first heat exchange section 41 and the second heat exchange section 42 can be suspended to increase ventilation, and the guide member 55 can promptly guide and discharge the condensate at the bottom of the indoor heat exchanger 40, thereby improving the heat exchange efficiency of the indoor heat exchanger 40 and enhancing the energy efficiency of the air conditioner.

[0104] For ease of description, in this embodiment, the faces of the first heat exchange section 41 and the second heat exchange section 42 facing the first air inlet 801 are defined as their respective front faces, and the faces facing away from the first air inlet 801 are defined as their respective back faces. The front and back faces of the first heat exchange section 41 and the second heat exchange section 42 are also distributed along the front-back direction of the air conditioner. The two faces of the first heat exchange section 41 and the second heat exchange section 42 arranged opposite each other in the horizontal direction are defined as their respective end faces. The two end faces of the first heat exchange section 41 are also distributed along the left-right direction of the air conditioner, and the two end faces of the second heat exchange section 42 are also distributed along the left-right direction of the air conditioner. The two faces of the first heat exchange section 41 and the second heat exchange section 42 arranged opposite each other in the vertical direction are defined as their respective side faces. The two side faces of the first heat exchange section 41 are also distributed along the up-down direction of the air conditioner, and the two side faces of the second heat exchange section 42 are also distributed along the up-down direction of the air conditioner.

[0105] In this design, the two adjacent sides of the first heat exchange section 41 and the second heat exchange section 42 are arranged at an angle, and both sides are located at the bottom of the indoor heat exchanger 40. Condensate on the first heat exchange section 41 flows along its surface to the side below it under gravity, and condensate on the second heat exchange section 42 flows along its surface to the side below it under gravity. Because the guide member 55 is positioned between the two adjacent sides of the first heat exchange section 41 and the second heat exchange section 42, it occupies less space and obstructs less indoor air entering the outer casing 80, thus improving heat exchange efficiency. Furthermore, since the two adjacent sides of the first heat exchange section 41 and the second heat exchange section 42 are in contact with the guide member 55, the condensate collected on these adjacent sides can be quickly guided to the guide member 55, preventing excessive condensate buildup on the adjacent sides and further improving heat exchange efficiency.

[0106] For example, the drainage element 55 extends from one end of the indoor heat exchanger 40 to the other. That is, the drainage element 55 is positioned between two adjacent sides of the first folded heat exchange section 41 and the second folded heat exchange section 42 along the left-right direction of the air conditioner. In other words, the length of the drainage element 55 along the left-right direction of the air conditioner is greater than or equal to the width of the indoor heat exchanger 40 along the left-right direction of the air conditioner. Thus, the drainage area of ​​the drainage element 55 along its length is relatively large, resulting in a better drainage effect. This allows condensate from all areas along the left-right direction of the two adjacent sides of the first folded heat exchange section 41 and the second folded heat exchange section 42 to be drained to the drainage element 55, resulting in high drainage efficiency. This improves the heat exchange efficiency of the indoor heat exchanger 40, thereby enhancing the energy efficiency of the air conditioner.

[0107] Based on the aforementioned embodiment, at least several or all of the portions of each of two adjacent sides along the direction from one end to the other of the indoor heat exchanger 40 abut against the flow guide 55. In this way, each portion of each of the two adjacent sides that directly abuts against the flow guide 55 can receive rapid flow, resulting in high flow efficiency.

[0108] Of course, as some alternatives, in this application, some portions of each of two adjacent sides along the direction from one end to the other of the indoor heat exchanger 40 abut against the flow guide 55, while the remaining portions do not abut against the flow guide 55. Exemplarily, the number of portions not directly abutting against the flow guide 55 can be one or more. In this case, the flow guide 55 can still function as a flow guide.

[0109] Of course, as an alternative, the length of the drainage component 55 along the left-right direction of the air conditioner can also be less than the width of the indoor heat exchanger 40, while still achieving the effect of condensate drainage. The ratio of the length of the drainage component 55 along the left-right direction of the air conditioner to the width of the indoor heat exchanger 40 can be set to, for example, 0.5 to 1.1, specifically 0.5, 0.6, 0.7, 0.8, 0.9, 1, or 1.1, etc. The specific value can be flexibly adjusted and set according to actual needs, and is not limited here.

[0110] Please see Figure 5 , Figure 13 and Figure 15 For example, the drainage member 55 is provided with a vent 5501, which extends through the drainage member 55 along its thickness direction. In this way, while the drainage member 55 drains condensate, it can also minimize the obstruction to airflow through the vent 5501. That is, indoor air can pass through the vent 5501 and come into contact with the two adjacent sides of the first heat exchange section 41 and the second heat exchange section 42, thereby ensuring high heat exchange efficiency.

[0111] For example, the ventilation section 5501 is provided with perforations, and there are multiple perforations arranged sequentially from one end to the other along the flow guide 55. In this way, since the flow guide 55 has perforations at various parts along its length, it has a ventilation function, which can reduce the adverse effect of the flow guide 55 on the ventilation of the bottom of the indoor heat exchanger 40; and the contact area between the two adjacent sides of the flow guide 55 and the first heat exchange section 41 and the second heat exchange section 42 is still large, which can ensure a good flow guide effect, thereby improving the heat exchange efficiency.

[0112] The more perforated holes there are and the denser the arrangement of the drainage element 55 along its length, the more obvious the ventilation effect and the smaller the adverse effect on the ventilation of the bottom of the indoor heat exchanger 40. Conversely, the fewer perforated holes there are and the sparser the arrangement of the drainage element 55 along its length, the less obvious the ventilation effect and the greater the adverse effect on the ventilation of the bottom of the indoor heat exchanger 40.

[0113] It should be noted that the cutouts include, but are not limited to, cutouts that are closed on all four sides or cutouts that are not closed on all four sides. The shape of the cutouts can be, for example, circular, polygonal, or other regular or irregular shapes, and is not limited here.

[0114] It should be noted that the ventilation section 5501 in this application has many specific design forms, and is not limited to the hollow holes or openings in the above embodiments. Moreover, the specific number is not limited, and can be flexibly adjusted and set according to actual needs. As long as ventilation is achieved without affecting the drainage effect of the drainage component 55, all are within the protection scope of this application.

[0115] Based on the aforementioned embodiments, the flow guide 55 includes a frame 551. The frame 551 has relatively high structural strength, ensuring that the flow guide 55 is not easily deformed and has a long service life. Specifically, the frame 551 is arranged, for example, within the angle formed by two adjacent sides of the first heat exchange section 41 and the second heat exchange section 42, and is closer to the mating position of the two adjacent sides than the first flow guide plate 552 and the second flow guide plate 553. In this way, the frame 551 is stably installed in the indoor heat exchanger 40, and has relatively little impact on the ventilation at the bottom of the indoor heat exchanger 40.

[0116] For example, the diversion element 55 also includes a first diversion plate 552. The first diversion plate 552 is connected to the frame 551 and is supported by the frame 551 to prevent deformation. The first diversion plate 552 also abuts against the side of the first folded heat exchange section 41, thereby diverting condensate from the side of the first folded heat exchange section 41 in a timely manner. Optionally, based on the arrangement of the diversion element 55 in the above embodiments, the first diversion plate 552 may also extend from one end of the first folded heat exchange section 41 to the other end, or be arranged in other ways, which will not be described in detail here.

[0117] In order to reduce the adverse effect of the first diversion plate 552 on the ventilation of the side of the first heat exchange section 41, the first diversion plate 552 is provided with a plurality of ventilation sections 5501, and the plurality of ventilation sections 5501 extend from one end of the first diversion plate 552 to the other end.

[0118] For example, the flow guide 55 also includes a second flow guide plate 553. The second flow guide plate 553 is connected to the frame 551 and is supported by the frame 551 to prevent deformation. The second flow guide plate 553 also abuts against the side of the second heat exchange section 42, thereby guiding the flow of condensate away from the side of the second heat exchange section 42 in a timely manner. Optionally, based on the arrangement of the flow guide 55 in the above embodiments, the second flow guide plate 553 may also extend from one end of the second heat exchange section 42 to the other end, or be arranged in other ways, which will not be described in detail here.

[0119] In order to reduce the adverse effect of the second diversion plate 553 on the ventilation of the side of the second heat exchange section 42, the second diversion plate 553 is provided with a plurality of ventilation openings 5501, and the plurality of ventilation openings 5501 extend from one end of the second diversion plate 553 to the other end.

[0120] It should be noted that in some embodiments, the skeleton 551 may be omitted from the drainage member 55, that is, only the first drainage plate 552 and the second drainage plate 553 are included. The first drainage plate 552 and the second drainage plate 553 are directly connected to each other.

[0121] Please see Figure 5 and Figure 15 For example, one side of the first diversion plate 552 is connected to the frame 551, and the other side of the first diversion plate 552 abuts against the side of the first folded heat exchange section 41, with the first diversion plate 552 and the side of the first folded heat exchange section 41 arranged at an angle. Thus, there is a ventilation gap between the first diversion plate 552 and the side of the first folded heat exchange section 41, ensuring ventilation of the side of the first folded heat exchange section 41 while allowing condensate to flow. Specifically, the top side of the first diversion plate 552 is connected to the frame 551, and the bottom side of the first diversion plate 552 abuts against the side of the first folded heat exchange section 41. More specifically, the first diversion plate 552 abuts against the bottom side of the first folded heat exchange section 41. The bottom side of the first folded heat exchange section 41 is designated as the first diversion part 411, where the condensate from the first folded heat exchange section 41 flows to the first diversion part 411 under gravity. The bottom side of the first diversion plate 552 abuts against the first diversion part 411. The specific contact method can be line contact or surface contact, etc., without much restriction. In this way, the first diversion plate 552 can quickly and promptly drain the condensate flowing into the first diversion part 411. Furthermore, other parts of the first diversion plate 552 do not need to contact the side of the first heat exchange section 41; that is, a ventilation gap is formed between it and the side of the first heat exchange section 41 to ensure that the ventilation effect is not affected.

[0122] Based on the aforementioned embodiments, to facilitate the drainage of condensate from the first drain plate 552, for example, the distance between the bottommost position of the first drain plate 552 and the bottom wall of the outer casing 80 is less than the distance between the first drain portion 411 and the bottom wall of the outer casing 80. Furthermore, the bottommost position of the first drain plate 552 is provided with a first water-cut angle 5521. Thus, when condensate gathers at the first water-cut angle 5521 under its own gravity, it can easily fall downwards through the first water-cut angle 5521 and be discharged, preventing it from flowing towards the side of the first heat exchange section 41.

[0123] Please see Figure 5 and Figure 15For example, one side of the second diversion plate 553 is connected to the frame 551, and the other side of the second diversion plate 553 abuts against the side of the second folded heat exchange section 42, with the second diversion plate 553 and the side of the second folded heat exchange section 42 arranged at an angle. Thus, there is a ventilation gap between the second diversion plate 553 and the side of the second folded heat exchange section 42, ensuring ventilation of the side of the second folded heat exchange section 42 while allowing condensate to flow. Specifically, the bottom side of the second diversion plate 553 is connected to the frame 551, and the top side of the second diversion plate 553 abuts against the side of the second folded heat exchange section 42. More specifically, the top side of the second diversion plate 553 abuts against the bottom of the side of the second folded heat exchange section 42. The bottom of the side of the second folded heat exchange section 42 is designated as the second diversion part 421, where the condensate from the second folded heat exchange section 42 flows to the second diversion part 421 under gravity. The top side of the second diversion plate 553 abuts against the second diversion part 421. The specific contact method can be line contact or surface contact, etc., without much restriction. In this way, the second diversion plate 553 can quickly and promptly drain the condensate flowing into the second diversion part 421. Furthermore, other parts of the second diversion plate 553 do not need to contact the side of the second heat exchange section 42; that is, a ventilation gap is formed between it and the side of the second heat exchange section 42 to ensure that the ventilation effect is not affected.

[0124] Based on the aforementioned embodiments, to facilitate the drainage of condensate from the second guide plate 553, for example, the distance between the bottommost position of the second guide plate 553 and the bottom wall of the outer casing 80 is less than the distance between the second drainage portion 421 and the bottom wall of the outer casing 80. Furthermore, the bottommost position of the second guide plate 553 is set as the second water-cut angle 5531. Thus, when condensate gathers at the second water-cut angle 5531 under its own gravity, it can easily fall downwards through the second water-cut angle 5531 and be discharged, thereby ensuring the drainage effect of the guide member 55 and preventing it from flowing to the side of the second heat exchange section 42.

[0125] It should be noted that the first water cut angle 5521 and the second water cut angle 5531 defined in this embodiment can be, for example, formed by two surfaces on the drain member 55 that are set at an angle. When the condensate flows to the water cut angle, it is easy to fall downwards under its own gravity.

[0126] To improve indoor air ventilation, the distance between the second drainage section 421 and the bottom wall of the outer casing 80 is greater than the distance between the first drainage section 411 and the bottom wall of the outer casing 80. That is, the overall side position of the first folded heat exchange section 41 is lower than the overall side position of the second folded heat exchange section 42. This results in a relatively larger amount of condensate accumulating on the side of the first folded heat exchange section 41. To facilitate faster drainage of this condensate, for example, the first drainage plate 552 has a third water-cut angle 5522 on the side opposite to the first folded heat exchange section 41. In other words, the sequential drainage action of the third water-cut angle 5522 and the first water-cut angle 5521 helps to quickly and promptly drain the condensate accumulated on the first drainage plate 552, thereby improving heat exchange efficiency.

[0127] For example, the frame 551 includes a first connecting plate 5511, a second connecting plate 5512, and a third connecting plate 5513. The first connecting plate 5511, the second connecting plate 5512, and the third connecting plate 5513 are connected sequentially. The side of the first connecting plate 5511 opposite to the side of the second connecting plate 5512 is connected to the first drainage plate 552. The side of the third connecting plate 5513 opposite to the side of the second connecting plate 5512 is connected to the second drainage plate 553.

[0128] In one specific embodiment, the first drainage plate 552, the skeleton 551 and the second drainage plate 553 are, for example, an integrated structure, including but not limited to metal parts integrally formed by sheet metal or die casting processes, or plastic parts integrally formed by injection molding processes.
