Description

Technical Field

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

[0002] In the field of air conditioning technology, high-efficiency and quiet cabinet air conditioners such as dual-flow cabinet air conditioners are widely used due to their advantages such as uniform air delivery and large air volume. However, at present, the surface of the leeward side of the components that make up the air duct of some cabinet air conditioners is prone to condensation due to the exchange of hot and cold air. In related technologies, heat insulation sponge is usually pasted on the surface of the leeward side to block heat transfer and reduce condensation. However, the heat insulation sponge is prone to aging and falling off after long-term use, resulting in a decrease in heat insulation performance. Condensation may still drip into the room or into the body, causing electrical component failure. Utility Model Content

[0003] This application discloses an air conditioner that can solve the problem of condensation dripping and ensure the normal operation of the internal electrical components of the air conditioner.

[0004] To achieve the above objectives, this application discloses an air conditioner, comprising:

[0005] Cabinet unit, the cabinet unit includes:

[0006] A housing having an air inlet;

[0007] A heat exchanger is disposed inside the housing and is used to exchange heat with the air entering the housing through the air inlet.

[0008] A heat exchange fan is disposed inside the housing and is used to introduce air into the housing through the air inlet;

[0009] A duct structure is disposed within the housing. An air duct is formed inside the duct structure. The air inlet of the air duct is connected to the air inlet. Air in the air duct can be blown into the indoor space through the air outlet of the air duct.

[0010] Drainage structure, the drainage structure comprising:

[0011] A water receiving component is disposed below the leeward side of the air duct structure to collect condensation formed on the surface of the leeward side of the air duct structure and discharge the condensation entering the water receiving component to the outside of the housing. The leeward side of the air duct structure is the side of the air duct structure that is away from the airflow in the air duct.

[0012] Thus, by installing a water-collecting device below the leeward side of the air duct structure, the water-collecting device can directly collect the condensation dripping from the leeward side surface, preventing the condensation from flowing along the leeward side surface of the panel frame or volute to the indoor floor or the interior of the unit, preventing electrical components from malfunctioning due to contact with water droplets, and improving the safety of use.

[0013] This application also provides an air conditioner, wherein the air duct structure includes:

[0014] A panel frame is provided with an air outlet, and the air outlet end of the air duct is connected to the air outlet so that the air in the air duct can be blown into the indoor space through the air outlet.

[0015] The water receiving component includes:

[0016] The first water receiving tank, wherein the water receiving component is disposed below the leeward side of the panel frame, is used to collect condensation formed on the surface of the leeward side of the panel frame.

[0017] In this way, the first water collection tank collects condensation on the leeward side of the panel frame separately, ensuring that the condensation formed on the surface of the leeward side of the panel frame can be completely intercepted and prevented from dripping into the cabinet or the ground.

[0018] This application also provides an air conditioner, wherein the air duct structure includes:

[0019] A volute, which is used to guide the air introduced into the housing by the heat exchange fan;

[0020] The water receiving component includes:

[0021] The second water collection tank is located below the leeward side of the volute and is used to collect condensation formed on the surface of the leeward side of the volute.

[0022] In this way, the second water collection tank collects condensation on the leeward side of the volute separately, ensuring that the condensation formed on the surface of the leeward side of the volute is completely intercepted and prevented from dripping into the cabinet or onto the ground.

[0023] This application also provides an air conditioner, wherein the air duct structure includes:

[0024] A volute, which is used to guide the air introduced into the housing by the heat exchange fan;

[0025] A panel frame is provided with an air outlet. The surface of the panel frame facing the heat exchange fan is spliced ​​with the volute to form an air duct. The air outlet end of the air duct is connected to the air outlet so that the air in the air duct can be blown into the indoor space through the air outlet.

[0026] The water receiving component includes:

[0027] The first water receiving tank, wherein the water receiving component is disposed below the leeward side of the panel frame, is used to collect condensation formed on the surface of the leeward side of the panel frame, and the first water receiving tank has a water outlet.

[0028] The second water collection trough is located below the leeward side of the volute and is used to collect condensation formed on the surface of the leeward side of the volute. At least a portion of the second water collection trough is located directly below the water outlet.

[0029] In this way, the panel frame is directly spliced ​​to one side of the air outlet of the volute, without the need to reserve additional independent air duct space. The two can work together to form a continuously gradually changing air duct cross section (narrow at the volute outlet and gradually widening at the panel frame air duct), reducing the unnecessary space occupation. In addition, the water collection device can collect the condensation formed on the leeward side of the panel frame and volute, preventing the condensation formed on the leeward side of the panel frame and volute from flowing onto the indoor floor or into the body, preventing electrical components from malfunctioning due to contact with water droplets, and improving the safety of use.

[0030] Furthermore, at least a portion of the second water receiving trough is located directly below the water outlet, allowing the condensate from the first water receiving trough to be automatically gravity-guided to the second water receiving trough through the water outlet. This eliminates the need for additional pipes or power equipment, resulting in a simple structure and high flow efficiency. In addition, the first and second water receiving troughs are arranged along the lower side of the leeward side of the panel frame and the volute, respectively, without occupying the horizontal space of the cabinet (such as the width and thickness direction), thus increasing the space utilization rate inside the casing.

[0031] This application also provides an air conditioner, wherein the depth of the cavity of the first water receiving tank is greater than or equal to 3 mm.

[0032] Thus, even if the ground where the cabinet unit is located is uneven to a certain extent, causing the first water receiving tray to tilt, the first water receiving tray can still effectively contain the condensate water that accumulates on the lower side due to the tilt; in addition, the 3mm depth also provides a buffer space for the water surface to slosh due to the shaking caused by the air conditioner's operation, thereby preventing the condensate water from overflowing from the first water receiving tray due to the shaking caused by the air conditioner's operation.

[0033] This application also provides an air conditioner, wherein the heat exchange fan includes two fans;

[0034] The volute includes:

[0035] In the first part, one of the two heat exchange fans is disposed in the first part;

[0036] The second part, along the width direction of the cabinet unit, is arranged side by side with the first part, and the other of the two heat exchange fans is arranged in the second part;

[0037] The second water collection tank is disposed between the leeward side of the first part and the leeward side of the second part, and the second water collection tank is capable of collecting condensation formed on the surfaces of the leeward side of the first part and the leeward side of the second part.

[0038] In this way, the volute is divided into two parallel sections, each accommodating two heat exchange fans, making the internal structure of the cabinet compact and orderly, effectively utilizing the space in the width direction of the cabinet, and facilitating the miniaturization of the product design; furthermore, the second water collection tank is arranged between the leeward sides of the two sections, which can collect the condensation generated on the leeward side surfaces of the first and second sections using the same second water collection tank, compared to setting two second water collection tanks to collect the condensation on the first and second sections respectively.

[0039] This application also provides an air conditioner, wherein the second water inlet is provided with a clearance opening, the clearance opening being used to avoid electrical component wires inside the housing.

[0040] In this way, the second water collection trough avoids squeezing and abrading the wires during installation or use, effectively preventing short circuits, leakage and other safety hazards caused by damage to the wire insulation layer, ensuring the safety of air conditioner operation, providing reasonable space for wire arrangement, and ensuring that the second water collection trough can completely cover the area between the first and second parts on the leeward side, giving full play to the function of collecting condensate. The size of the second water collection trough will not be reduced or the installation position of the second water collection trough will not be changed to avoid electrical components and wires, ensuring the condensate collection effect and preventing condensate from contacting the wires and causing their performance degradation or damage.

[0041] This application also provides an air conditioner, wherein the drainage structure further includes:

[0042] A water receiving tray is disposed inside the housing and located below the heat exchanger. The water receiving tray is used to collect condensate formed on the heat exchanger, and the condensate entering the water receiving tray can be discharged to the outside of the housing.

[0043] By placing the water collection tray below the heat exchanger inside the casing, condensation generated on the surface of the heat exchanger can be accurately collected, preventing condensation from dripping and polluting the indoor environment or seeping into the equipment and corroding electrical components, thus affecting airflow circulation. At the same time, the collected condensation can be discharged to the outside of the casing through the drain pipe, which not only ensures the safety and stability of the equipment operation, but also facilitates regular cleaning and maintenance, prevents blockage of the drain pipe, ensures long-term efficient operation of the air conditioner, and improves product reliability and user experience.

[0044] This application also provides an air conditioner, wherein the water receiving component is located above the water receiving tray so that the condensate in the water receiving component can flow into the water receiving tray and be discharged to the outside of the housing through the water receiving tray.

[0045] By placing the water receiving component above the water receiving tray, the characteristics of gravity can be fully utilized, allowing the condensate collected by the water receiving component to flow naturally into the water receiving tray below without external force, simplifying the drainage process and reducing energy consumption and failure risk. Furthermore, this layout achieves vertical integration of the drainage structure, eliminating the need for additional horizontal pipes or complex diversion structures, thereby reducing the lateral space occupied by the drainage structure inside the shell and improving the compactness of the layout inside the shell.

[0046] This application also provides an air conditioner, wherein an isolation member is provided at the water outlet, the isolation member being used to prevent condensation formed on the surface of the leeward side of the panel frame from flowing toward the surface of the panel frame facing the heat exchange fan.

[0047] In this way, the condensation formed on the leeward side of the panel frame can be effectively blocked from flowing to the surface of the panel frame facing the heat exchange fan, preventing condensation from dripping onto the heat exchange fan and its related electrical components, thus preventing short circuits, abnormal noises and other malfunctions.

[0048] This application also provides an air conditioner, wherein the isolation member is a barrier rib disposed at the water outlet, and the barrier rib extends toward the second water receiving tank along the thickness direction of the panel frame, so that the condensate formed on the barrier rib can drip into the second water receiving tank.

[0049] In this way, the barrier ribs achieve physical isolation in a rib-like shape, occupying little space and not affecting the overall internal layout of the shell. At the same time, the precise extension direction guides the condensate on the leeward side of the panel frame, allowing it to drip directly into the second water collection tank under gravity. This prevents the disorderly flow of condensate from contaminating the heat exchange fan and surrounding electrical components, reducing the risk of short circuits and corrosion. Furthermore, the condensate formed on the surface of the barrier ribs themselves can also slide smoothly into the water collection tank, achieving full-process collection of condensate, ensuring unobstructed drainage paths, and improving the drainage efficiency of the drainage structure.

[0075] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0076] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0077] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0078] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0079] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components whose specific types and structures may be the same or different, and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0080] As mentioned in the background section, in related technologies, heat transfer is usually blocked by attaching thermal insulation sponge to the surface of the leeward side of the components that constitute the air duct, so as to reduce condensation. However, after long-term use, the thermal insulation sponge is prone to aging and falling off, resulting in a decrease in heat insulation performance. Condensation may still drip into the room or into the machine body, causing electrical component failure.

[0081] To address the aforementioned issues, this application provides an air conditioner in which a water collection device is positioned below the leeward side of the duct structure to collect condensation formed on the leeward side surface of the duct structure and discharge the condensation entering the water collection device to the outside of the housing. This prevents condensation from flowing along the leeward side surface of the panel frame or volute to the indoor floor or the interior of the unit, thus preventing electrical components from malfunctioning due to contact with water droplets.

[0082] The following will describe specific embodiments and appendices. Figure 1-12 The technical solution of the air conditioner in this application will be further explained.

[0083] like Figure 1 As shown, air conditioner 1 may include a cabinet unit 10.

[0084] like Figure 1 As shown, the cabinet unit 10 may include a housing 11, on which an air inlet 11a is provided. The housing 11 is the external structural frame of the cabinet unit 10, used to house internal components and to provide support, protection and fixation. It also constitutes the main appearance of the air conditioner 1. The air inlet 11a is an air inlet opened on the housing 11 for drawing in indoor air.

[0085] like Figures 2 to 4 As shown, the cabinet unit 10 may also include a heat exchanger 12, which is disposed inside the housing 11. The heat exchanger 12 is used to exchange heat with the air entering the housing 11 through the air inlet 11a. It is usually composed of copper tubes (or aluminum tubes) and fins. When the air enters the housing 11 through the air inlet 11a, it flows over the surface of the heat exchanger 12. Heat is transferred through the circulation of refrigerant (such as Freon) in the pipes of the heat exchanger 12. When cooling, the refrigerant absorbs heat from the air to cool it down. When heating, the refrigerant releases heat to heat the air, thereby achieving the purpose of regulating the indoor temperature.

[0086] like Figure 4 As shown, the cabinet unit 10 may also include a heat exchange fan 13, which is disposed inside the housing 11. The heat exchange fan 13 is used to introduce air into the housing 11 through the air inlet 11a. The heat exchange fan 13 may be a cross-flow fan, which is driven by a motor to rotate the fan blades, forming an air pressure difference in the housing 11, drawing outside air into the housing 11 through the air inlet 11a, so that the air flows through the heat exchanger 12 to complete heat exchange, and then is delivered to the room through the air duct structure 14 to realize the circulation of air and temperature regulation.

[0087] like Figure 4 As shown, the cabinet unit 10 may also include an air duct structure 14, which is disposed inside the housing 11. An air duct 14c is formed inside the air duct structure 14. The air inlet end of the air duct 14c is connected to the air inlet 11a. The air in the air duct 14c can be blown into the indoor space through the air outlet end of the air duct 14c.

[0088] like Figure 5 As shown, the cabinet unit 10 may also include a drainage structure 100.

[0089] like Figure 3 As shown, the drainage structure 100 may include a water receiving member 110, which is disposed below the leeward side of the air duct structure 14. The water receiving member 110 is used to collect condensation formed on the surface of the leeward side of the air duct structure 14 and discharge the condensation entering the water receiving member 110 to the outside of the housing 11. The leeward side of the air duct structure 14 is the side of the air duct structure 14 that is away from the airflow in the air duct 14c.

[0090] During the operation of the air conditioner 1, the surface of the leeward side of the duct structure 14 is closer to the indoor ambient temperature because it does not directly contact the airflow in the duct 14c. When the air conditioner 1 is in cooling mode, the surface temperature of the heat exchanger 12 is low. The air flowing through the heat exchanger 12 is cooled down to form a low-temperature airflow. When the low-temperature airflow flows in the duct 14c, it will transfer the cooling capacity through the windward side (the side that directly contacts the airflow) of the duct structure 14, causing the surface temperature of the leeward side (the side that does not contact the airflow) to gradually decrease. If the surface temperature of the leeward side is lower than the dew point temperature of the indoor air, the water vapor in the air will condense on its surface to form condensation.

[0091] In this embodiment, by setting a water receiving component 110 below the leeward side of the air duct structure component 14, the water receiving component 110 can directly collect the condensation dripping from the leeward side surface, preventing the condensation from flowing along the leeward side surface of the panel frame 14b or the volute 14a to the indoor floor or the interior of the machine body, preventing electrical components from malfunctioning due to contact with water droplets, and improving the safety of use.

[0092] Furthermore, it abandons the easily aging and falling-off thermal insulation sponge, and achieves mechanical collection and discharge of condensation water through structural design, avoiding the recurrence of condensation problems caused by the failure of thermal insulation materials. At the same time, it reduces the pasting process, simplifies the production process, and improves assembly efficiency.

[0093] In addition, the water receiving part 110 is integrated below the air duct structure 14, which does not occupy the internal space of the air duct 14c, avoids interfering with the airflow, and ensures that the air volume, air speed and temperature uniformity of the air supplied by the air conditioner 1 are not affected, thus maintaining efficient heat exchange performance.

[0094] In some possible embodiments, the air duct structure 14 may include a panel frame 14b, on which an air outlet 14b1 is provided. The air outlet end of the air duct 14c is connected to the air outlet 14b1 so that the air of the air duct 14c can be blown into the indoor space through the air outlet 14b1. The panel frame 14b is the appearance structure of the front side of the cabinet 10, and its air outlet 14b1 can be a vertical strip or a grille-shaped opening.

[0095] The water receiving component 110 may include a first water receiving trough 1101. The water receiving component 110 is disposed below the leeward side of the panel frame 14b and is used to collect condensation formed on the surface of the leeward side of the panel frame 14b.

[0096] Thus, the first water collection tank 1101 is positioned below the leeward side of the panel frame 14b, so that the first water collection tank 1101 can collect the condensation formed on the surface of the leeward side of the panel frame 14b, preventing the condensation formed on the surface of the leeward side of the panel frame 14b from flowing onto the indoor floor or the interior of the machine, preventing electrical components from malfunctioning due to contact with water droplets, and improving the safety of use.

[0097] In some possible embodiments, the air duct structure 14 may include a volute 14a for guiding the air introduced into the housing 11 by the heat exchange fan 13. The volute 14a surrounds the outside of the heat exchange fan 13 and is able to convert the radial (perpendicular to the fan axis) airflow blown out by the heat exchange fan 13 into an axial (parallel to the fan axis) airflow, so that it flows along the height direction of the cabinet 10.

[0098] The water receiving component 110 may also include a second water receiving trough 1102, which is disposed below the leeward side of the volute 14a and is used to collect condensation formed on the surface of the leeward side of the volute 14a.

[0099] Thus, the second water collection tank 1102 is positioned below the leeward side of the volute 14a and below the leeward side of the panel frame 14b, so that the second water collection tank 1102 can collect the condensation formed on the surfaces of the panel frame 14b and the leeward side of the volute 14a, preventing the condensation formed on the surface of the leeward side of the volute 14a from flowing onto the indoor floor or into the machine body, preventing electrical components from malfunctioning due to contact with water droplets, and improving the safety of use.

[0100] In some possible embodiments, such as Figure 3 and Figure 4 As shown, the air duct structure 14 may include a volute 14a, which is used to guide the air introduced into the housing 11 by the heat exchange fan 13.

[0101] The air duct structure 14 may also include a panel frame 14b, on which an air outlet 14b1 is provided. The surface of the panel frame 14b facing the heat exchange fan 13 is spliced ​​with the volute 14a to form an air duct 14c. The air outlet end of the air duct 14c is connected to the air outlet 14b1 so that the air in the air duct 14c can be blown into the indoor space through the air outlet 14b1.

[0102] In this way, the panel frame 14b is directly spliced ​​on one side of the air outlet 14b1 of the volute 14a, without the need to reserve additional space for the independent air duct 14c. The two can work together to form a continuously gradually changing air duct cross section (narrow outlet of volute 14a, widening air duct at part of panel frame), reducing the unnecessary space occupation.

[0103] like Figures 5 to 7 As shown, the water receiving component 110 may include a first water receiving tank 1101. The water receiving component 110 is disposed below the leeward side of the panel frame 14b and is used to collect condensation formed on the surface of the leeward side of the panel frame 14b. The first water receiving tank 1101 is provided with a water outlet 1101a.

[0104] like Figure 5 , Figure 8 and Figure 9 As shown, the water receiving component 110 may further include a second water receiving trough 1102, which is disposed below the leeward side of the volute 14a and is used to collect condensation formed on the surface of the leeward side of the volute 14a. At least a portion of the second water receiving trough 1102 is located directly below the outlet 1101a so that the condensation in the first water receiving trough 1101 can enter the second water receiving trough 1102 through the outlet 1101a.

[0105] Thus, when condensation forms on the leeward side of the panel frame 14b due to contact between hot and cold air, water droplets flow downwards along the surface and fall directly into the first water receiving trough 1101 (located below the leeward side of the panel frame 14b). The condensation in the first water receiving trough 1101 falls vertically downwards through the outlet 1101a to the lower second water receiving trough 1102 by gravity. The condensation formed on the leeward side of the volute 14a flows downwards along the surface and falls directly into the second water receiving trough 1102 (located below the leeward side of the volute 14a). The two streams of condensation converge in the second water receiving trough 1102 and are finally discharged to the outside of the housing 11 through the drainage path of the second water receiving trough 1102 (such as a connected drain pipe).

[0106] Thus, the first water collection trough 1101 collects condensation on the leeward side of the panel frame 14b separately, and the second water collection trough 1102 collects condensation on the leeward side of the volute 14a separately, ensuring that the condensation on the surface of the air duct structure 14 is completely intercepted, preventing it from dripping into the cabinet 10 or onto the ground. Furthermore, at least a portion of the second water collection trough 1102 is located directly below the water outlet 1101a. The condensation in the first water collection trough 1101 is automatically gravity-guided to the second water collection trough 1102 through the water outlet 1101a, without the need for additional pipes or power equipment. The structure is simple and the flow guiding efficiency is high. In addition, the first water collection trough 1101 and the second water collection trough 1102 are arranged below the leeward side of the panel frame 14b and the volute 14a respectively, without occupying the lateral space of the cabinet 10 (such as the width and thickness direction), thus increasing the space utilization rate inside the housing 11.

[0107] In some possible embodiments, the depth of the cavity of the first water receiving tank 1101 is greater than or equal to 3 mm.

[0108] In this embodiment, the cavity depth of the first water receiving tank 1101 is greater than or equal to 3mm. Even if the ground where the cabinet unit 10 is located is uneven to a certain extent, causing the first water receiving tank 1101 to tilt, the first water receiving tank 1101 can still effectively accommodate the condensed water that accumulates on the lower side due to the tilt. In addition, the 3mm depth also provides a buffer space for the water surface to slosh due to the shaking caused by the operation of the air conditioner 1, thereby preventing the condensed water from overflowing the first water receiving tank 1101 due to the shaking caused by the operation of the air conditioner 1.

[0109] In some possible embodiments, such as Figure 4 As shown, the heat exchange fan 13 may include two. For example, the dual-flow cabinet air conditioner 10 has two cross-flow fans, which are installed horizontally side by side in front of the heat exchanger 12 inside the air conditioner 1, and work together in a symmetrical or staggered layout.

[0110] like Figure 4 and Figure 8 As shown, the volute 14a may include a first part 14a1, in which one of the two heat exchange fans 13 is disposed.

[0111] like Figure 4 and Figure 8 As shown, the volute 14a may also include a second part 14a2. Along the width direction of the cabinet 10, the second part 14a2 is arranged side by side with the first part 14a1, and the other of the two heat exchange fans 13 is arranged in the second part 14a2.

[0112] like Figure 8 As shown, the second water receiving tank 1102 is disposed between the leeward side of the first part 14a1 and the leeward side of the second part 14a2. The second water receiving tank 1102 is capable of collecting condensation formed on the surfaces of the leeward side of the first part 14a1 and the leeward side of the second part 14a2.

[0113] Thus, the volute 14a is divided into two parallel sections, each accommodating two heat exchange fans 13, making the internal structure of the cabinet 10 compact and orderly, effectively utilizing the space in the width direction of the cabinet 10, and facilitating the miniaturization of the product design; furthermore, the second water collection tank 1102 is arranged between the leeward sides of the two sections, and can use the same second water collection tank 1102 to collect the condensate generated on the leeward side surfaces of the first section 14a1 and the second section 14a2, which is better than setting two second water collection tanks 1102 to collect the condensate on the first section 14a1 and the second section 14a2 respectively.

[0114] In some possible embodiments, such as Figure 9As shown, the second water tank 1102 is provided with a clearance opening 1102a, which is used to avoid the wires of electrical components inside the housing 11.

[0115] Inside the housing 11, electrical component wires are essential. For example, the compressor's power cord provides the power required for its operation; the signal line connecting the control board and the heat exchange fan 13 transmits control commands to adjust the speed of the heat exchange fan 13; and the temperature sensor's connection line transmits the collected temperature signal to the main control chip. These wires are all electrical component wires. In this embodiment, a clearance opening 1102a is provided on the second water inlet 1102 to avoid the electrical component wires inside the housing 11, preventing the second water inlet 1102 from squeezing or abrading the wires during installation or use, and effectively preventing short circuits and leaks caused by damage to the wire insulation layer. To eliminate electrical and other safety hazards, ensure the safe operation of air conditioner 1, and provide reasonable space for the wiring, making the wiring more orderly and convenient for installers and maintenance personnel, improving production and maintenance efficiency, and ensuring that the second water collection tank 1102 can completely cover the area between the first part 14a1 and the second part 14a2 on the leeward side, so as to fully utilize the function of collecting condensate. The size of the second water collection tank 1102 will not be reduced or the installation position of the second water collection tank 1102 will not be changed due to avoiding electrical components and wires, ensuring the condensate collection effect and preventing condensate from contacting the wires and causing their performance to degrade or be damaged.

[0116] In some possible embodiments, such as Figure 10 and Figure 11 As shown, the drainage structure 100 also includes a water receiving tray 1103, which is disposed inside the shell 11 and located below the heat exchanger 12. The water receiving tray 1103 is used to collect condensate formed on the heat exchanger 12, and the condensate entering the water receiving tray 1103 can be discharged to the outside of the shell 11.

[0117] The water receiving tray 1103 is placed below the heat exchanger 12 inside the shell 11, which can accurately collect the condensate generated on the surface of the heat exchanger 12, preventing the condensate from dripping randomly and polluting the indoor environment or seeping into the equipment to corrode electrical components and affect airflow circulation. At the same time, the collected condensate can be discharged to the outside of the shell 11 through the drain pipe, which not only ensures the safety and stability of the equipment operation, but also facilitates regular cleaning and maintenance, prevents the drain pipe from being blocked, ensures the long-term efficient operation of the air conditioner 1, and improves product reliability and user experience.

[0118] In some possible embodiments, such as Figure 5 As shown, the water receiving component 110 is located above the water receiving tray 1103 so that the condensate in the water receiving component 110 can flow into the water receiving tray 1103 and be discharged to the outside of the housing 11 through the water receiving tray 1103.

[0119] In this way, by placing the water receiving component 110 above the water receiving tray 1103, the characteristics of gravity can be fully utilized, allowing the condensate collected by the water receiving component 110 to flow naturally into the water receiving tray 1103 below without external force, simplifying the drainage process and reducing energy consumption and failure risk. Furthermore, this layout achieves the vertical integration of the drainage structure 100 without the need for additional horizontal pipes or complex diversion structures, thereby reducing the lateral space occupied by the drainage structure 100 inside the housing 11 and improving the compactness of the layout inside the housing 11.

[0120] Specifically, when the cabinet unit 10 is running, the condensation formed on the leeward side of the panel frame 14b is collected by the first water receiving trough 1101 and falls into the lower second water receiving trough 1102 by gravity through the water outlet 1101a. At the same time, the condensation formed on the leeward side of the volute 14a also drips directly into the second water receiving trough 1102. The condensation collected in the second water receiving trough 1102 continues to flow downward and falls into the water receiving tray 1103 located below. Finally, the water receiving tray 1103 is discharged from the outside of the housing 11 through the water outlet 1101a and the drain pipe.

[0121] In some possible embodiments, such as Figure 12 As shown, an isolation element 1101b is provided at the water outlet 1101a. The isolation element 1101b is used to prevent condensation formed on the leeward side of the panel frame 14b from flowing to the surface of the panel frame 14b facing the heat exchange fan 13.

[0122] An isolator 1101b is installed at the water outlet 1101a to effectively block the condensation formed on the leeward side of the panel frame 14b from flowing towards the surface of the panel frame 14b facing the heat exchange fan 13. This prevents the condensation from dripping onto the heat exchange fan 13 and its related electrical components, thus preventing short circuits, abnormal noises, and other malfunctions. At the same time, it prevents the condensation from mixing into the airflow and polluting the indoor environment, reduces corrosion of the panel frame 14b components, and guides the condensation to quickly flow into the drainage path, improving drainage efficiency.

[0123] In some possible embodiments, such as Figure 12 As shown, the isolation member 1101b is a barrier rib provided at the drain outlet. Along the thickness direction of the panel frame 14b, the barrier rib extends toward the second water receiving tank 1102 so that the condensate formed on the barrier rib can drip into the second water receiving tank 1102.

[0124] The barrier ribs achieve physical isolation in a rib-like shape, occupying little space and not affecting the overall internal layout of the shell 11. At the same time, the condensation on the leeward side of the panel frame 14b is guided by a precise extension direction, allowing it to drip directly into the second water receiving tank 1102 under gravity. This prevents the disorderly flow of condensation from contaminating the heat exchange fan 13 and surrounding electrical components, reducing the risk of short circuits and corrosion. Furthermore, the condensation formed on the surface of the barrier ribs themselves can also slide smoothly into the water receiving tank, achieving full-process collection of condensation, ensuring unobstructed drainage path, and improving the drainage efficiency of the drainage structure 100.

[0125] Of course, the isolation element 1101b is not limited to the above form. The isolation element 1101b can also be a drainage channel. A U-shaped channel, a stepped channel or other structure can be directly processed on the panel frame 14b or the housing 11. One end of the channel is connected to the second water receiving channel 1102, and the other end extends to the condensate generation area on the leeward side. Alternatively, a hydrophobic coating / film can be applied to the leeward side surface of the panel frame 14b (or the surface of the isolation element 1101b) with a hydrophobic material (such as polytetrafluoroethylene or silicone coating) or a hydrophobic film can be pasted to reduce the surface tension and allow the condensate to gather into beads and quickly slide down to the second water receiving channel 1102.
