[0003] This disclosure relates to the field of electrical technology, specifically to an air conditioner. Background Technology

[0004] Air conditioners can be recessed ceiling-mounted units. One type of recessed ceiling-mounted unit mainly consists of two parts: the indoor unit and the panel assembly. The indoor unit is designed with mounting lugs and is suspended from the ceiling via a rod. The panel assembly is fixed to the indoor unit with screws. After the indoor unit is installed in the ceiling, the four edges of the panel assembly fit flush with the ceiling.

[0005] The indoor unit mainly includes a casing, air duct components, evaporator components, water pump assembly, and drip tray assembly. The drip tray assembly is used to collect condensate from the evaporator. The water pump assembly actively drains the condensate from the drip tray via a water pump and drain pipe.

[0006] However, when using existing embedded ceiling systems, problems such as malfunctions in the electronic control motherboard and water pump components may occur, causing the water pump to malfunction and resulting in a continuous increase in condensate in the drip tray, which in turn causes the condensate to overflow from the drip tray and drip everywhere.

[0007] Summary of the Invention

[0008] To address the aforementioned technical problems, an air conditioner is provided according to embodiments of this disclosure, which aims to at least partially solve the technical problem of condensate overflowing from the drip tray and dripping everywhere.

[0009] According to some embodiments of this disclosure, an air conditioner is provided, including: a housing with an air inlet; a heat exchanger disposed within the housing; and a water receiving assembly disposed within the housing and located below the heat exchanger. The water receiving assembly has a water receiving groove and an overflow hole communicating with the water receiving groove. Along the air inlet direction, the projection of the overflow hole on the housing is offset from the projection of the air inlet on the housing. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

If the specific posture changes, the directional indications will also change accordingly.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0035] The technical solutions of this disclosure are described below with reference to the accompanying drawings and specific embodiments.

[0036] According to some embodiments of this disclosure, an air conditioner is provided that aims to at least partially solve the technical problem of condensate overflowing from the drip tray and dripping everywhere.

[0037] Figure 1 is a structural schematic diagram of an air conditioner according to some embodiments of the present disclosure; Figure 2 is a schematic diagram showing the separation of the faceplate assembly and the main body of the air conditioner in Figure 1; Figure 3 is an exploded view of the main body in Figure 2; Figure 4 is an exploded view of the faceplate assembly in Figure 2. As shown in Figures 1, 2, 3 and 4, the air conditioner according to some embodiments of the present disclosure includes: a housing 10, a heat exchanger 20 and a water receiving assembly 30. The housing 10 has an air inlet 101. The heat exchanger 20 is disposed inside the housing 10. The water receiving assembly 30 is disposed inside the housing 10 and located below the heat exchanger 20. The water receiving assembly 30 has a water receiving groove 301 and an overflow hole 302 communicating with the water receiving groove 301. Along the air intake direction, the projection of the overflow hole 302 on the housing 10 is offset from the projection of the air inlet 101 on the housing 10.

[0038] Air conditioners can be recessed ceiling units.

[0039] Heat exchanger 20 can be an evaporator.

[0040] In some embodiments of the present disclosure, the housing 10 has an air inlet 101, the heat exchanger 20 is disposed inside the housing 10, and the water receiving assembly 30 is disposed inside the housing 10 and located below the heat exchanger 20. The water receiving assembly 30 has a water receiving tank 301 and an overflow hole 302 communicating with the water receiving tank 301. When a malfunction occurs in the main control board, water pump assembly 60, or other components that cause the water pump to malfunction, the condensate in the water receiving assembly 30 will gradually increase. By setting the overflow hole 302 to a set water level in the water receiving assembly 30, when the condensate level in the water receiving assembly 30 exceeds the set water level, the condensate will flow out through the overflow hole 302, thereby preventing the condensate from overflowing the water receiving assembly 30 and dripping everywhere, and ensuring the user experience.

[0041] The water receiving component 30 has a water receiving groove 301 and an overflow hole 302 connected to the water receiving groove 301, which enables the water receiving component 30 to have water receiving and overflow functions, realizing the integration of multiple functions into the water receiving component 30, thereby reducing costs.

[0042] Because the projection of the overflow hole 302 on the housing 10 is offset from the projection of the air inlet 101 on the housing 10 along the air intake direction, the projection of the overflow hole 302 on the housing 10 will not overlap with the projection of the air inlet 101 on the housing 10. In other words, the overflow hole 302 will not block the air inlet 101, allowing the air entering the housing 10 through the air inlet 101 to fully exchange heat with the heat exchanger 20. This ensures the air intake area of ​​the air inlet 101 and the heat exchange efficiency of the heat exchanger 20, further improving the user experience. When air enters the housing 10 through the air inlet 101, it will not blow onto the condensate discharged from the overflow hole 302, thus preventing condensate from being blown into the housing 10 and affecting the safety of the electrical equipment inside the housing 10. The condensate drained from the overflow hole 302 drips down under the action of gravity, which can remind the user that the air conditioner has a fault in the main control board, water pump assembly, etc., which causes the water pump to be unable to work properly, so as to facilitate timely troubleshooting.

[0043] As shown in Figure 2, in some embodiments, along the air inlet direction, the projection of the overflow hole 302 on the housing 10 is offset from the projection of the heat exchanger 20 on the housing 10. That is, the projection of the overflow hole 302 on the housing 10 will not overlap with the projection of the heat exchanger 20 on the housing 10. In other words, the overflow hole 302 will not block the heat exchanger 20, so that the air entering the housing 10 through the air inlet 101 can fully exchange heat with the heat exchanger 20, thereby ensuring the heat exchange efficiency of the heat exchanger 20 and further improving the user experience.

[0044] Figure 5 is a structural schematic diagram of the water receiving assembly in Figure 3 from a first-view perspective; Figure 6 is an enlarged schematic diagram of point A in Figure 5; Figure 7 is a structural schematic diagram of the water receiving assembly in Figure 3 from a second-view perspective; Figure 8 is a rear view of the water receiving assembly in Figure 3; Figure 9 is an enlarged schematic diagram of point B in Figure 8. As shown in Figures 5, 6, 7, 8, and 9, in some embodiments, in order to enable the water receiving assembly 30 to have both water receiving and overflow functions, the water receiving tank 301 includes: a water receiving section 3011 and an overflow section 3012. The overflow section 3012 is connected to the water receiving section 3011 at an included angle. The overflow hole 302 is connected to the overflow section 3012.

[0045] In some embodiments, the water receiving section 3011 is located below the heat exchanger 20. When the air conditioner is cooling, the condensate generated on the heat exchanger 20 drips into the water receiving section 3011. The condensate in the water receiving section 3011 can be pumped out by the air conditioner's water pump assembly to achieve the function of draining condensate. When the water pump fails to work properly due to problems such as malfunctions in the main control board or water pump assembly, the condensate in the water receiving section 3011 will gradually increase and flow into the overflow section 3012. The overflow hole 302 is set at the set water level of the water receiving assembly 30, so that when the condensate level in the water receiving assembly 30 exceeds the set water level, the condensate will flow out sequentially through the overflow section 3012 and the overflow hole 302, thereby preventing condensate from overflowing the water receiving assembly 30 and dripping everywhere and ensuring the user experience.

[0046] When the air conditioner is working, air enters the casing 10 through the air inlet 101, which blows the condensate on the water collection section 3011. If the air volume is large and the overflow hole 302 is connected to the water collection section 3011, the condensate on the water collection section 3011 may be blown out through the overflow hole 302, affecting the user experience. As shown in Figure 5, in some embodiments, in order to avoid blowing out the overflowing condensate and affecting the safety of the air conditioner's electrical components, the overflow hole 302 is connected to the overflow section 3012. Compared to connecting it to the water collection section 3011, this allows the overflow hole 302 to be located away from the air inlet area of ​​the heat exchanger 20, thereby ensuring that the condensate can flow out normally, ensuring the safety of the air conditioner's electrical components and improving the user experience.

[0047] If the overflow hole 302 is connected to the water receiving section 3011, the relatively long length of the water receiving section 3011 makes it impossible to accurately determine the overflow location when the water pump malfunctions due to problems with the main control board, water pump components, etc., resulting in a larger condensate dripping area. This makes electrical safety protection difficult and increases the risk of electrical safety problems. As shown in Figure 5, in some embodiments, to ensure an accurate overflow location, the length of the overflow section 3012 is shorter than the length of the water receiving section 3011, and the overflow hole 302 is connected to the overflow section 3012. This allows for accurate determination of the condensate overflow location when it is discharged from the overflow hole 302, thereby reducing the condensate dripping area, facilitating protection, and lowering the electrical safety risk.

[0048] If the overflow hole 302 is connected to the water receiving section 3011, the relatively long length of the water receiving section 3011 poses a risk of distortion and deformation of the overflow hole 302 after injection molding, affecting the overflow of condensate. As shown in Figure 5, in some embodiments, to ensure that condensate can overflow normally, the length of the overflow section 3012 is shorter than the length of the water receiving section 3011, and the overflow hole 302 is connected to the overflow section 3012. That is, the overflow hole 302 is located in the overflow section 3012 to facilitate injection molding, thereby reducing the possibility of distortion and deformation of the overflow hole 302, making the structure of the overflow hole 302 highly reliable, and thus ensuring that condensate can be discharged normally.

[0049] If the overflow hole 302 is connected to the water receiving section 3011, the overflow hole 302 will be relatively close to the heat exchanger 20. During normal operation of the air conditioner, there is a risk that condensate will overflow the overflow hole 302 and drip directly. As shown in Figures 3 and 5, in some embodiments, to avoid this risk during normal operation, the overflow hole 302 is connected to the overflow section 3012, moving the overflow hole 302 away from the heat exchanger 20. This ensures that condensate will not overflow the overflow hole 302 and drip directly during normal operation, improving the user experience.

[0050] As shown in Figures 2 and 3, in some embodiments, along the air inlet direction, the projection of the overflow section 3012 on the housing 10 is offset from the projection of the air inlet 101 on the housing 10. Therefore, the projection of the overflow section 3012 on the housing 10 will not overlap with the projection of the air inlet 101 on the housing 10. In other words, the overflow section 3012 will not block the air inlet 101, so that the air entering the housing 10 through the air inlet 101 can fully exchange heat with the heat exchanger 20, thereby ensuring the air inlet area of ​​the air inlet 101 and the heat exchange efficiency of the heat exchanger 20, further improving the user experience.

[0051] As shown in Figures 2 and 3, in some embodiments, along the air inlet direction, the projection of the overflow section 3012 on the housing 10 is offset from the projection of the heat exchanger 20 on the housing 10. That is, the projection of the overflow section 3012 on the housing 10 will not overlap with the projection of the heat exchanger 20 on the housing 10. Therefore, the overflow section 3012 will not block the heat exchanger 20, allowing the air entering the housing 10 through the air inlet 101 to fully exchange heat with the heat exchanger 20, thereby ensuring the heat exchange efficiency of the heat exchanger 20 and further improving the user experience.

[0052] As shown in Figure 5, in some embodiments, the included angle between the water receiving section 3011 and the overflow section 3012 can be an acute angle, a right angle, or an obtuse angle. When the included angle between the water receiving section 3011 and the overflow section 3012 is a right angle, the water receiving section 3011 and the overflow section 3012 are perpendicular. However, the perpendicular relationship between the water receiving section 3011 and the overflow section 3012 is not absolutely perpendicular in a geometric sense; the angular relationship between the water receiving section 3011 and the overflow section 3012 can be in the range of 90±3°.

[0053] In some embodiments, since the overflow hole 302 is configured to communicate with the overflow section 3012, the overflow hole 302 can occupy only a small portion of the area of ​​the overflow section 3012. This simplifies the structure of the overflow hole 302 and the overflow section 3012, making them easier to manufacture and reducing manufacturing costs. Because only one overflow hole 302 is provided, in the event of a malfunction in the electrical control board, water pump assembly, or other components that prevent the water pump from operating normally, the condensate in the overflow section 3012 can flow out only through this overflow hole 302. This minimizes the area over which the condensate drips, reducing the risk of electrical safety problems and facilitating electrical safety protection.

[0054] As shown in Figures 1 and 2, in some embodiments, the housing 10 includes a body 103 and a face frame assembly 104 connected to the body 103. The face frame assembly 104 is supported by the body 103, and an air inlet 101 is provided on the face frame assembly 104.

[0055] As shown in Figures 3 and 5, in some embodiments, to ensure the sealing performance of the air conditioner, the overflow section 3012 has a first side and a second side disposed opposite to each other, with the first side located between the second side and the air inlet 101. The overflow hole 302 is formed on the first side.

[0056] The second side of the overflow section 3012 is fixed to the folded edge of the air conditioner's chassis 1011. After the main body 103 is connected to the face frame assembly 104, the housing 10 is sealed together by the second side, the folded edge of the chassis 1011, and the face frame assembly 104. If the overflow hole 302 is located on the second side, air and water leakage may occur. In some embodiments, to reduce the possibility of air and water leakage, the overflow hole 302 is located on the first side, ensuring the airtightness of the air conditioner.

[0057] The face frame assembly 104 has an air inlet grille 107, and the second side extends beyond the area of ​​the air inlet grille 107. If the overflow hole 302 is opened on the second side, the condensate flowing out of the overflow hole 302 will flow onto the panel 109 of the face frame assembly 104. The panel 109 is generally a concave curved surface. When the condensate flows onto the panel 109, the condensate will accumulate and affect the operation of the electrical components of the air conditioner. It is also easy for bacteria to grow, thus affecting the user experience. Figure 10 is a schematic diagram of the cooperation between the face frame assembly and the water receiving assembly of the air conditioner in Figure 1; Figure 11 is a cross-sectional view taken along CC in Figure 10; Figure 12 is an enlarged schematic diagram of point D in Figure 10. Combining Figures 10, 11 and 12, in some embodiments, in order to drain the condensate flowing out of the overflow hole 302, the overflow hole 302 is opened on the first side, which is located in the area of ​​the air inlet grille 107, so that the overflow hole 302 is opposite to the air inlet grille 107. Condensate can be discharged sequentially through overflow hole 302 and air inlet grille 107, thereby preventing condensate from accumulating and ensuring the normal operation of the air conditioner's electrical components. It also prevents condensate from flowing onto panel 109, thus avoiding the accumulation of condensate and the growth of bacteria, and ensuring the user's experience.

[0058] Figure 13 is an exploded view of the faceplate assembly and water-receiving assembly in Figure 10. Referring to Figures 2 and 13, in some embodiments, to ensure the safety of the electronic components 105, the housing 10 further includes a faceplate assembly 104 connected to the body 103. The faceplate assembly 104 is equipped with the electronic components 105. The overflow hole 302 and the electronic components 105 are located at the two ends of the water-receiving section 3011. The water-receiving section 3011 is located on both sides of the centerline along the length direction of the housing 10, and the electronic components 105 can be electrical components such as display devices, receivers, and control devices.

[0059] In some embodiments, when a malfunction occurs in the electronic control board, water pump assembly, or other components, causing the water pump to malfunction, the condensate in the water receiving assembly 30 will gradually increase. The overflow hole 302 is located at the set water level of the water receiving assembly 30. When the condensate level in the water receiving assembly 30 exceeds the set water level, the condensate will flow out through the overflow hole 302. The overflow hole 302 and the electronic component 105 are located at the two ends of the water receiving section 3011, respectively, so that the overflow hole 302 is far away from the electronic component 105. This prevents the condensate flowing out of the overflow hole 302 from flowing towards the electronic component 105, avoids short circuit faults in the electronic component 105, and ensures the safety of the electronic component 105.

[0060] Referring to Figures 4 and 13, in some embodiments, to ensure the safety of the actuator 108, the housing 10 further includes a faceplate assembly 104 connected to the body 103, on which the actuator 108 connected to the air guide 106 is disposed. The overflow hole 302 and the actuator 108 are located at the two ends of the overflow section 3012, respectively. The overflow section 3012 is located at both ends of the center line in the width direction of the housing 10.

[0061] In some embodiments, when a malfunction occurs in the electronic control board, water pump assembly, or other components, causing the water pump to malfunction, the condensate in the water receiving assembly 30 will gradually increase. The overflow hole 302 is located at a set water level in the water receiving assembly 30. When the condensate level in the water receiving assembly 30 exceeds the set water level, the condensate will flow out through the overflow hole 302. The overflow hole 302 and the actuator 108 are located at opposite ends of the overflow section 3012, keeping the overflow hole 302 away from the actuator 108. This prevents the condensate flowing from the overflow hole 302 from flowing towards the actuator 108, avoiding a short circuit in the actuator 108 and ensuring its safety.

[0062] As shown in Figure 2, in some embodiments, the housing 10 has a driver mounting base 102. A driver 108 can be mounted on the driver mounting base to support the driver 108 via the driver mounting base 102. The overflow port 302 and the driver mounting base 102 are located at two ends of the overflow section 3012, respectively.

[0063] As shown in Figure 3, in some embodiments, during normal operation of the air conditioner, to prevent condensate from flowing directly out of the overflow hole 302 from the heat exchanger 20, the heat exchanger 20 is inclinedly disposed within the housing 10 and has a first end and a second end higher than the first end. Along the air inlet direction, the distance between the projection of the overflow hole 302 on the housing 10 and the projection of the first end on the housing 10 is greater than the distance between the projection of the overflow hole 302 on the housing 10 and the projection of the second end on the housing 10.

[0064] In some embodiments, condensate will be generated on the heat exchanger 20 during the cooling process of the air conditioner. Along the air inlet direction, the distance between the projection of the overflow hole 302 on the housing 10 and the projection of the first end on the housing 10 is greater than the distance between the projection of the overflow hole 302 on the housing 10 and the projection of the second end on the housing 10. Furthermore, there is a height difference between the overflow hole 302 and the second end, which makes the overflow hole 302 far away from the heat exchanger 20. Therefore, there is no risk that the condensate dripping from the heat exchanger 20 will directly flow out of the water collection assembly 30 through the overflow hole 302 when the heat exchanger 20 is too close to the overflow hole 302, thus ensuring the reliability of the air conditioner operation and improving the user experience.

[0065] Referring to Figure 12, in some embodiments, in order to discharge the condensate flowing out of the overflow hole 302, the housing 10 also includes a face frame assembly 104 connected to the body 10, and the face frame assembly 104 has a drain hole 1010 communicating with the overflow hole 302.

[0066] In some embodiments, when a malfunction occurs in the main control board, water pump assembly, or other components, causing the water pump to malfunction, the condensate in the water receiving assembly 30 will gradually increase. The overflow hole 302 is located at the set water level of the water receiving assembly 30. When the condensate level in the water receiving assembly 30 exceeds the set water level, the condensate will flow out sequentially through the overflow hole 302 and the drain hole 1010, thus preventing condensate accumulation. This ensures the normal operation of the air conditioner's electrical components and prevents condensate from flowing onto the panel 109, thereby preventing condensate buildup and bacterial growth, and ensuring a better user experience.

[0067] In some embodiments, along the air intake direction, the projection of the drain hole 1010 on the housing 10 is offset from the projection of the air inlet 101 on the housing 10. That is, the projection of the drain hole 1010 on the housing 10 does not overlap with the projection of the air inlet 101 on the housing 10. When air enters the housing 10 through the air inlet 101, it will not blow onto the condensate drained from the drain hole 1010, preventing condensate from being blown into the housing 10 and affecting the safety of the electrical equipment inside the housing 10. The condensate drained from the drain hole 1010 drips down under the influence of gravity, which can remind the user that the air conditioner has malfunctions in the main control board, water pump assembly, etc., causing the water pump to malfunction and allowing for timely repair.

[0068] Referring to Figures 5, 6, 7, 8, 9, and 12, in some embodiments, to allow the condensate discharged from the overflow hole 302 to flow to the drain hole 1010, the air conditioner further includes a guide member 50. The guide member 50 is connected to the water receiving assembly 30 and connects the overflow hole 302 and the drain hole 1010. The guide member 50 directs the condensate from the overflow hole 302 smoothly to the drain hole 1010, preventing uncertain flow direction and ensuring accurate overflow position of the water receiving assembly 30. This reduces the dripping range of the condensate, facilitating electrical safety protection and lowering the risk of electrical safety problems.

[0069] Referring to Figures 5, 6, and 12, in some embodiments, to allow the condensate discharged from the overflow hole 302 to flow to the drain hole 1010, the guide member 50 further includes a guide portion 501 and a connecting portion (not shown in the figures). The guide portion 501 is connected to the water receiving assembly 30 and has a guide groove 5011 connecting the overflow hole 302 and the drain hole 1010. The connecting portion is connected to the guide portion 501 and / or the face frame assembly 104 and has a water guiding channel connecting the guide groove and the drain hole 1010. The connecting portion is angled to the guide portion 501.

[0070] In some embodiments, the condensate flowing out of the overflow hole 302 can flow through the guide channel 5011 to the drain hole 1010, allowing the condensate 102 to be discharged smoothly. Moreover, the guide channel can prevent external environmental factors from affecting the flow of the condensate 102, ensuring that the condensate 102 can flow smoothly to the drain hole 1010.

[0071] In some embodiments, in order to ensure structural strength, the guide section 501 can be integrally formed with the overflow section 3012 of the water receiving component 30, thereby reducing processing steps and lowering costs.

[0072] In some embodiments, in order to ensure the structural strength of the guide section 501, a reinforcing member 502 is provided on the guide section 501, which can reduce the possibility of the guide section 501 being twisted and deformed, so that the condensate can be discharged normally.

[0073] Referring to Figures 7 and 9, in some embodiments, in order to avoid the reinforcing member 502 interfering with the flow of condensate in the guide channel 5011, the reinforcing member 502 and the guide channel 5011 are located on opposite sides of the guide portion 501, so that the condensate in the guide channel 5011 can flow smoothly to the connecting portion.

[0074] Referring to Figures 5, 6, 7, 8, and 9, in some embodiments, the heat exchanger 20 is inclined within the housing 10. To fully receive the condensate from the heat exchanger 20, the water receiving assembly 30 further includes a main water receiving tray 303, a support frame 304, and auxiliary water receiving trays 305. The main water receiving tray 303 has a water receiving groove 301 and an overflow hole 302. The support frame 304 is connected to the main water receiving tray 303. Multiple auxiliary water receiving trays 305 are connected to the support frame 304 and are located below the heat exchanger 20. The multiple auxiliary water receiving trays 305 are arranged sequentially at intervals along the inclined surface of the heat exchanger 20. Along the height direction of the housing 10, the projections of the multiple auxiliary water receiving trays 305 on the base of the housing 10 are connected end to end. An air gap is provided between adjacent auxiliary water receiving trays 305 to allow air to pass through.

[0075] In some embodiments, when condensate is generated in the heat exchanger 20, under the influence of gravity, a portion of the condensate flows downwards along the inclined surface of the heat exchanger 20 and into the main condensate tray 303; another portion of the condensate drips downwards from the inclined surface of the heat exchanger 20 into multiple auxiliary condensate trays 305. By utilizing the multiple auxiliary condensate trays 305 of the main condensate tray 303 to collect the condensate dripping downwards from the heat exchanger 20, condensate is prevented from dripping onto the chassis of the housing 10 or from falling into the room through the air inlet 101 on the chassis, thereby improving the user experience.

[0076] Figure 15 is a schematic diagram of the assembly of the electronic control component in Figure 3; Figure 16 is a top view of the electronic control component in Figure 15; Figure 17 is a cross-sectional view taken along EE in Figure 16; Figure 18 is an enlarged schematic diagram at point F in Figure 17; Figure 19 is an enlarged schematic diagram at point G in Figure 17. Referring to Figures 15, 16, 17, 18, and 19, in some embodiments, to facilitate the assembly of the air conditioner, a support groove 3041 capable of supporting the electronic control component 40 is provided on the end face of the support frame 304 opposite to the auxiliary water receiving tray 305.

[0077] In some embodiments, when assembling an air conditioner, one end of the electronic control component 40 can be placed in the support groove 3041 and the other end can be placed on the edge of the housing 10, so that the electronic control component 40 is tilted and supported by the support frame 304 and the housing 10, so as to facilitate wiring of the electronic control box.

[0078] In some embodiments, in order to ensure the structural strength of the water receiving assembly 30, the main water receiving tray 303, the support frame 304 and the auxiliary water receiving tray 305 are integrally formed, thereby reducing processing steps and lowering processing costs.

[0079] In some embodiments, the water receiving component 30 has a notch to form an overflow hole 302, and the edges of the water receiving component 30 do not need to be high in order to save materials and reduce costs.

[0080] In some embodiments of the present disclosure, the housing has an air inlet, a heat exchanger is disposed inside the housing, and a water receiving assembly is disposed inside the housing and located below the heat exchanger. The water receiving assembly has a water receiving tank and an overflow hole communicating with the water receiving tank. When a malfunction occurs in the main control board, water pump assembly, or other components, causing the water pump to malfunction, the condensate in the water receiving assembly will gradually increase. By setting the overflow hole at a set water level on the water receiving assembly, when the condensate level in the water receiving assembly exceeds the set water level, the condensate will flow out through the overflow hole, thereby preventing the condensate from overflowing the water receiving assembly and dripping everywhere, and ensuring a good user experience.

[0081] The water receiving assembly has a water receiving trough and an overflow hole connected to the water receiving trough, which enables the water receiving assembly to have both water receiving and overflow functions, thus giving the water receiving assembly multiple functions and reducing costs.

[0082] Because the projection of the overflow hole on the casing is offset from the projection of the air inlet on the casing along the air intake direction, the projection of the overflow hole on the casing will not overlap with the projection of the air inlet on the casing. In other words, the overflow hole will not block the air inlet, allowing the air entering the casing through the air inlet to fully exchange heat with the heat exchanger. This ensures the air intake area of ​​the air inlet and the heat exchange efficiency of the heat exchanger, further improving the user experience. When air enters the casing from the air inlet, it will not blow onto the condensate discharged from the overflow hole, thus preventing condensate from being blown into the casing and affecting the safety of the electrical equipment inside. The condensate discharged from the overflow hole drips down under gravity, alerting the user to potential problems with the air conditioner's main control board, water pump components, etc., that may be causing the water pump to malfunction, facilitating timely troubleshooting.
