Abstract

This application discloses an air conditioner. The housing of the display module includes a main housing and an extended housing. The main housing has a second wiring port, and the extended housing is connected to one side of the main housing and at least partially corresponds to the second wiring port, forming a water-blocking channel between them. The water-blocking channel includes a first sub-channel and a second sub-channel that are interconnected. A first opening of the first sub-channel allows the other end of a conductive wire to pass through and enter the first sub-channel, and the opening direction of the first opening is different from the opening direction of the second wiring port. Along the height direction of the housing, the connection point between the second sub-channel and the first sub-channel is located above the first opening and the second wiring port. In this way, the conductive wire forms an upward and then downward trajectory within the water-blocking channel. When condensation occurs on the surface of the conductive wire, the water flows naturally to a lower position under the influence of gravity, thereby intercepting the condensation at the connection point between the first and second sub-channels, preventing it from directly flowing into the display module and causing the display module to malfunction.

Description

Technical Field

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

[0002] Air conditioners typically consist of an indoor unit and an outdoor unit, with the outdoor unit usually located indoors. To allow users to easily observe the operating status of the indoor unit (e.g., temperature, mode), the display module is usually mounted on the front of the unit (e.g., integrated into the display panel). The heat exchanger, as the core component of the indoor unit, typically occupies most of the internal space, resulting in a relatively close proximity between the display module and the heat exchanger. The inventors discovered that when the indoor unit is cooling, the heat exchanger absorbs heat from the air through a phase change of the refrigerant (liquid to gas), causing a rapid drop in the surface temperature of the heat exchanger. Simultaneously, the temperature of the display module also becomes relatively low, leading to condensation on its surface. If this condensation flows into the display module, it can cause a circuit malfunction, affecting the normal operation of the entire indoor unit.

[0003] In related technologies, to prevent condensation from flowing into the display module, a sloping guide surface is typically provided on one side of the display module's mounting box to direct condensation from the module surface to a drain, thereby reducing the possibility of condensation entering the display module. However, condensation can also occur on the conductive lines of the display module, and this condensation can still flow into the display module along with the conductive lines, potentially causing circuit malfunctions. Utility Model Content

[0004] This application discloses an indoor air conditioner unit that can prevent condensation generated on the conductive wire from flowing into the display module and causing display module failure.

[0005] To achieve the above objectives, this application discloses an indoor air conditioning unit, comprising:

[0006] Indoor unit, the indoor unit includes:

[0007] A housing having an inner cavity;

[0008] A heat exchanger, wherein the heat exchanger is disposed within the inner cavity;

[0009] An electrical box is disposed within the inner cavity and along the length of the housing. The electrical box is spaced apart from the heat exchanger. A control main board is provided inside the electrical box, and a first wiring port is provided in the electrical box.

[0010] The display module is disposed in the inner cavity, along the length of the housing, and is located on the side of the heat exchanger closer to the electrical box;

[0011] The display module includes:

[0012] The housing has an internal installation space and a second cable routing port communicating with the installation space. Along the height direction of the housing, the second cable routing port is located below the first cable routing port.

[0013] A circuit board, wherein the circuit board is disposed in the mounting space;

[0014] A conductive wire, one end of which passes through the first wiring port to be electrically connected to the control motherboard, and the other end of which passes through the second wiring port to extend into the mounting space and be electrically connected to the circuit board.

[0015] The housing includes:

[0016] The main housing forms the mounting space, and the main housing is provided with the second wiring port;

[0017] An outer casing, the outer casing being connected to one side of the main casing and at least partially corresponding to the second wiring port, a water-blocking channel being formed between the outer casing and the main casing, the water-blocking channel comprising:

[0018] A first sub-channel having a first opening configured to allow the other end of the conductive wire to pass through and enter the first sub-channel, and the opening direction of the first opening being different from the opening direction of the second wiring port;

[0019] The second sub-channel is connected to the first sub-channel and the second wiring port. Along the height direction of the housing, the connection between the second sub-channel and the first sub-channel is located above the first opening and the second wiring port. The second sub-channel is configured to allow the other end of the conductive wire to pass through to enter the second wiring port and electrically connect to the circuit board.

[0020] The air conditioner of this application features an extended casing that forms a water-blocking channel between the extended casing and the main casing. This water-blocking channel is constructed to include a first sub-channel and a second sub-channel, with the first opening of the first sub-channel for the conductive wire to enter the water-blocking channel and the second opening of the second sub-channel for the conductive wire to enter the installation space having different directions. This forces the conductive wire to be turned when passing through the first and second sub-channels to enter the installation space, preventing it from extending directly into them. Furthermore, this application defines the connection point between the second sub-channels along the height of the casing as being above the first opening and the second wiring opening; that is, the conductive wire forms an upward-downward path within the water-blocking channel. In this way, when condensation occurs on the surface of the conductive wire, the condensation will naturally flow to lower areas due to gravity. That is, the condensation will first flow to the first sub-channel, which is located at a lower position, thus preventing the condensation from flowing into the second sub-channel. This can block the condensation generated on the conductive wire from the second wiring port and even outside the installation space, thereby preventing the condensation from flowing into the installation space and causing malfunctions in the display module's circuitry.

[0021] As can be seen, this application has designed the structure of the housing to change the routing path of the conductive wires. In particular, it utilizes the principle of gravity to allow the condensate on the conductive wires to automatically collect in the first sub-channel and even in the position of the main housing away from the second wiring port. This can prevent the condensate from flowing into the installation space and causing malfunctions to the circuit of the display module. The overall solution has a simple structure, which helps to simplify the structural design of the display module of the air conditioner.

[0022] As an optional implementation, the main housing is provided with a water-blocking part protruding towards the outer housing near the second wiring port, and the water-blocking part and the outer housing form the water-blocking channel.

[0023] Since conductive wires are usually quite flexible, in order to ensure that the conductive wires can form an upward and then downward path within the water-blocking channel as described above, a water-blocking part protruding towards the outer shell is provided on the main housing. This allows a water-blocking channel to be formed through the gap between the water-blocking part and the outer shell, thereby ensuring the accuracy of the conductive wire's path and preventing condensate from entering the display module and affecting its normal operation due to changes in the conductive wire's path during long-term use of the air conditioner.

[0024] Furthermore, the design of the water-blocking part can better construct the water-blocking channel. At the same time, the protruding design of the water-blocking part can also be used to ensure that the connection between the first sub-channel and the second sub-channel is located above the first opening and the second opening, thereby better guiding the conductive wire to form an upward and then downward path within the first sub-channel and the second sub-channel.

[0025] As an optional implementation, the water-blocking part includes:

[0026] The water guide surface is positioned close to the first opening and is inclined so that the width of the water-blocking part gradually increases from the outer shell to the main shell along the length direction of the housing. The water guide surface is used to guide the water flow on the conductive wire to the side of the main shell away from the second wiring opening.

[0027] The water-blocking part includes a water-guiding surface, which is positioned close to the first opening and inclined so that the width of the water-blocking part gradually increases from the outer casing to the main casing along the length of the casing. This allows the water-guiding surface to be inclined towards the side where the first opening is located. Therefore, when condensate on the surface of the conductive wire enters the water-blocking channel from the first opening due to high flow rate or large volume, the water-guiding surface will also change its flow trajectory by lateral guidance, thereby guiding the condensate along the water-guiding surface to the side of the main casing away from the second wiring opening. This prevents the condensate from reaching the connection between the first and second sub-channels, and thus prevents condensate from entering the second wiring opening.

[0028] As an optional implementation, the main housing includes:

[0029] A first housing, having a top surface, a second wiring port located on the top surface, and an outer housing connected to the top surface;

[0030] The second shell is provided on top of the first shell. The second shell is provided with a guide groove, one end of which is connected to the top surface to guide the condensate on the conductive wire to flow in.

[0031] The second shell has a flow guide groove, one end of which is connected to the top surface, which is the surface of the first shell with the second wiring port. When the condensate on the conductive wire flows to the top surface of the first shell through the first opening of the first sub-channel, the condensate on the top surface can flow into the flow guide groove. The flow guide groove can then promptly drain the condensate accumulated on the top surface, thus avoiding the risk of leakage due to excessive condensate accumulation on the top surface.

[0032] As an optional implementation, the mounting space is formed inside the first housing, and the circuit board is disposed within the mounting space;

[0033] The second shell includes:

[0034] A back plate, the first housing is disposed on the back plate, and the opening of the mounting space faces away from the back plate, and the back plate is provided with the flow guide groove;

[0035] Side panels, which surround and connect to the edge of the back panel to cover the outer periphery of the first shell.

[0036] An installation space is formed inside the first housing, and the circuit board is placed within the installation space. The second housing includes a back plate, and the first housing covers the back plate. The opening of the installation space faces away from the back plate, and a guide channel is formed on the back plate. This makes the installation space inside the first housing an independent semi-enclosed area, connected to the outside only through a second wiring port. This allows for physical isolation between the installation space and the guide channel of the second housing, preventing condensate from entering the installation space when flowing inside the guide channel.

[0037] As an optional implementation, the air conditioner further includes:

[0038] A water collection tray is connected to the housing and is located below the heat exchanger along the height direction of the housing. The water collection tray is configured to collect the condensate flowing down from the heat exchanger.

[0039] The second shell has a drain outlet on the side near the heat exchanger, and the drain outlet is located below the first shell along the height direction of the shell. The drain outlet is provided corresponding to and connected to the water receiving tray to discharge condensate into the water receiving tray.

[0040] By positioning the drain outlet below the first casing along the height of the casing, the condensate in the guide channel can flow naturally to the drain outlet by gravity, eliminating the need for additional power devices such as water pumps. This helps improve the efficiency and stability of condensate drainage.

[0041] In addition, the drip tray itself is used to collect the condensate produced by the heat exchanger. By setting the drain outlet to correspond to and connect to the drip tray, the condensate from the display module and the condensate from the heat exchanger can be drained through the same drip tray, eliminating the need for a separate drainage component and thus helping to reduce the manufacturing cost of the air conditioner.

[0042] As an alternative implementation, along the length of the housing, the guide channel and the drain outlet are spaced apart, and the drain outlet is closer to the heat exchanger than the guide channel. The surface of the second housing with the drain outlet is constructed as an inclined surface, the guide channel extends to the inclined surface, and the inclined surface is configured to guide the condensate from the guide channel to the drain outlet.

[0043] The surface of the second shell with a drain outlet is constructed as an inclined surface, and the guide channel extends to the inclined surface. When the condensate in the guide channel flows into the inclined surface, it will flow rapidly towards the drain outlet under the influence of the gravitational force generated by the slope, thereby improving the efficiency of condensate drainage.

[0044] As an optional implementation, the second shell further includes:

[0045] Two flow guides are provided, both of which are located on the side of the second housing where the drain outlet is provided. Along the height direction of the housing, the flow guides are located below the drain outlet, and along the length direction of the housing, the two flow guides are located on both sides of the opening of the drain outlet.

[0046] Along the depth direction of the housing, the flow guide includes:

[0047] A first end, the first end being disposed away from the housing;

[0048] The second end is disposed opposite to the first end and is constructed as an inclined end so that the width of the guide portion gradually decreases from the second housing toward the drain pan along the depth direction of the housing, so as to guide the condensate to flow toward the water receiving pan.

[0049] The guide section forms a tapering shape that gradually narrows from top to bottom along the depth direction of the casing. This allows condensate to flow from the drain outlet, converging at the narrow end under the guidance of the guide section and ultimately dripping into the drip tray as a concentrated stream. This ensures that the condensate discharged from the drain outlet is more concentrated, preventing it from flowing outside the drip tray.

[0050] As an optional implementation, the top surface of the first shell is inclined toward the guide channel to guide condensate into the guide channel; and / or,

[0051] The top surface of the first shell is provided with a water-blocking rib. Along the length direction of the shell, the water-blocking rib is adjacent to and spaced apart from the first opening. The water-blocking rib is configured to block the flow of condensate from the first opening to the top surface, so that the condensate flows into the guide groove.

[0052] By setting the top surface to be inclined towards the guide channel, the condensate water accumulated on the top surface can be quickly guided to the guide channel, thereby improving the drainage rate of the condensate water and preventing water from accumulating on the top surface and leaking into the display module.

[0053] By setting water-blocking ribs on the top surface, and along the length of the shell, the water-blocking ribs are positioned near and spaced apart from the first opening. This allows the water-blocking ribs and the water-blocking channel to form an enclosed barrier, causing the condensate on the conductive wire to accumulate in this area. This ensures that the condensate can only flow into the guide channel, preventing it from flowing and spreading randomly and entering other components, thus affecting the normal operation of the air conditioner.

[0054] As an optional implementation, the outer shell is provided with a stop portion located at the first opening. The stop portion is used to abut against the conductive wire located outside the first opening, so that at least a portion of the conductive wire connected to the stop portion is bent, and the bent portion of the conductive wire is provided corresponding to the guide groove to guide the condensate on the conductive wire into the guide groove.

[0055] The outer shell has a contact portion located at the first opening, which is used to abut the conductive wire outside the first opening, so that at least a portion of the conductive wire connected to the contact portion is bent. This allows the conductive wire to be bent by the contact portion, and the bent portion corresponds to the flow channel, thereby forming a V-shaped bend in the conductive wire. Consequently, the condensate on the conductive wire will preferentially flow towards the lowest end of the bend under the influence of gravity, and thus flow into the flow channel.

[0056] Furthermore, since the abutment part is used to abut the conductive wire outside the first opening, it is equivalent to first allowing the condensate on the conductive wire to flow into the guide groove through the bending part before the water blocking channel. That is, the abutment part and the water blocking channel of this application are actually constructed as a secondary water blocking design for the conductive wire. The abutment part first blocks the condensate on the conductive wire that has not yet entered the water blocking channel, thereby reducing the condensate on the conductive wire. On this basis, when the conductive wire enters the water blocking channel after the first water blocking, it can block the water a second time due to the blocking effect of the water blocking channel, thereby better preventing the condensate generated by the conductivity from flowing into the display module along the conductive wire.

[0057] It is evident that by employing the anti-contact portion and water-blocking channel of this application, condensation on the conductive wire can be better prevented from flowing into the display module along the conductive wire, thereby helping to ensure the stable use of the display module.

[0058] Compared with the prior art, the beneficial effects of this application are:

[0059] The air conditioner provided in this application features an extended casing that forms a water-blocking channel between the extended casing and the main casing. This water-blocking channel is constructed to include a first sub-channel and a second sub-channel, with the first opening of the first sub-channel for the conductive wire to enter the water-blocking channel and the second opening of the second sub-channel for the conductive wire to enter the installation space having different directions. This forces the conductive wire to be turned when passing through the first and second sub-channels to enter the installation space, preventing it from extending directly into them. Furthermore, this application defines the connection point between the second sub-channels along the height of the casing as being above the first opening and the second wiring opening, meaning the conductive wire forms an upward-downward path within the water-blocking channel. In this way, when condensation occurs on the surface of the conductive wire, the condensation will naturally flow to lower areas due to gravity. That is, the condensation will first flow to the first sub-channel, which is located at a lower position, thus preventing the condensation from flowing into the second sub-channel. This can block the condensation generated on the conductive wire from the second wiring port and even outside the installation space, thereby preventing the condensation from flowing into the installation space and causing malfunctions in the display module's circuitry.

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.

[0084] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), 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.

[0085] Air conditioners typically consist of an indoor unit and an outdoor unit, with the indoor unit usually located indoors. To allow users to easily observe the operating status of the indoor unit (such as temperature and mode), the display module is usually mounted on the front of the unit (e.g., integrated into the display panel). Since the heat exchanger is the core component of the indoor unit, it typically occupies most of the space inside the unit; therefore, the display module is relatively close to the heat exchanger.

[0086] The inventors discovered that when the indoor unit is cooling, the heat exchanger inside absorbs heat from the air through the phase change of the refrigerant (from liquid to gas), causing a sharp drop in the surface temperature of the heat exchanger. Simultaneously, the temperature of the display module also drops relatively low, leading to condensation on its surface. If this condensation flows into the display module, it can cause circuit malfunctions, affecting the normal operation of the entire indoor unit.

[0087] In related technologies, to prevent condensation from flowing into the display module, a sloping guide surface is typically provided on one side of the display module's mounting box to direct condensation from the module surface to a drain, thereby reducing the possibility of condensation entering the display module. However, condensation can also occur on the conductive lines of the display module, and this condensation can still flow into the display module along with the conductive lines, potentially causing circuit malfunctions.

[0088] Based on this, this application discloses an air conditioner. The housing of the display module includes a main housing and an extended housing. The main housing has a second wiring port, and the extended housing is connected to one side of the main housing and at least partially corresponds to the second wiring port, forming a water-blocking channel between them. The water-blocking channel includes a first sub-channel and a second sub-channel that are interconnected. A first opening of the first sub-channel allows the other end of a conductive wire to pass through and enter the first sub-channel, and the opening direction of the first opening is different from the opening direction of the second wiring port. Along the height direction of the housing, the connection point between the second sub-channel and the first sub-channel is located above the first opening and the second wiring port. The housing of the display module is composed of a main housing and an extended housing, which cooperate to form a water-blocking channel. The water-blocking channel includes a first sub-channel and a second sub-channel that are interconnected. The second sub-channel is connected to the second wiring port. The first opening of the first sub-channel and the opening direction of the second wiring port are different, which requires the conductive wire to be turned and passed through to enter the installation space. In addition, along the height of the casing, the connection point between the two sub-channels is located above the first opening and the second wiring opening. This causes the conductive wires to form an upward and then downward trajectory within the water-blocking channel. As a result, when condensation occurs on the surface of the conductive wires, the water flows naturally to a lower position due to gravity, thus intercepting the condensation at the connection point between the first and second sub-channels. This prevents the condensation from flowing directly into the installation space of the display module and causing the display module to malfunction.

[0089] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0090] Please refer to the following: Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of an air conditioner provided in an embodiment of this application. Figure 2 This is a schematic diagram of the internal structure of the cavity provided in an embodiment of this application. Figure 3 A front view of the housing provided in an embodiment of this application. Figure 4 This is a rear view of the housing provided in an embodiment of this application. This application discloses an air conditioner 200, which typically includes an indoor unit 100 and an outdoor unit. The indoor unit 100 is the part of the air conditioner 200 that directly interacts with the indoor environment and is mainly used for treating indoor air (e.g., heating, cooling, circulation, or purification). The outdoor unit is used for compressing the refrigerant and absorbing or releasing heat.

[0091] In some embodiments, such as Figure 1 , Figure 2 As shown, the indoor unit 100 includes a casing 1, which has an inner cavity 11. The casing 1 is a housing 41 that protects the internal components of the indoor unit 100 of the air conditioner 200 from damage caused by external impacts or dust intrusion. The heat exchanger 2, fan, electrical control components, etc. are housed in the inner cavity 11, thereby providing them with physical protection and preventing damage caused by external impacts or dust intrusion.

[0092] Since air conditioner 200 is typically installed on an indoor wall, taking the installed state of air conditioner 200 as an example, the height direction of housing 1 is from the bottom to the top of housing 1, which is also the vertical direction. Housing 1 also has a width direction and a depth direction. Specifically, the width direction of housing 1 is from one end to the other end of housing 1, the front side of housing 1 is the side facing the user, and the depth direction is from the front side to the rear side of housing 1. Among the width direction, depth direction, and height direction of housing 1, any two pairs are perpendicular or approximately perpendicular.

[0093] In some embodiments, the indoor unit 100 includes a heat exchanger 2 disposed within the inner cavity 11. The heat exchanger 2 is used to perform a phase change of the refrigerant (evaporation absorbing heat or condensation releasing heat), thereby transferring heat with the indoor air and regulating the indoor temperature. When the indoor unit 100 is in cooling mode, the heat exchanger 2 is the heat-absorbing end. Low-temperature, low-pressure liquid refrigerant flows into the heat exchanger 2 and rapidly evaporates into a gaseous state. During this process, it absorbs heat from the indoor hot air flowing through the heat exchanger 2, lowering the air temperature. The cooled air is then blown back into the room by a fan, achieving cooling. When the indoor unit 100 is in heating mode, the heat exchanger 2 becomes the heat-releasing end. High-temperature, high-pressure gaseous refrigerant flows into the heat exchanger 2 and condenses into a liquid state within the heat exchanger 2, releasing heat during the process. The indoor fan drives cold air to flow through the heat exchanger 2, absorbs heat, and then becomes hot air, which is blown back into the room, achieving heating.

[0094] In some embodiments, the indoor unit 100 includes an electrical box 3, which is disposed within the inner cavity 11 and spaced apart from the heat exchanger 2 along the length of the casing 1. The electrical box 3 contains a control main board (not shown in the figure) and a first wiring port 32. The electrical box 3 coordinates the circuit operation of the indoor unit 100, implementing control logic for command reception, signal processing, and component driving, while also providing space for the installation and protection of the internal control main board and other components.

[0095] In some embodiments, the indoor unit 100 includes a display module 4, which is disposed in the inner cavity 11. Along the length of the casing 1, the display module 4 is located on the side of the heat exchanger 2 near the electrical box 3. The display module 4 is used to provide feedback to the user on the operating status of the air conditioner 200 (e.g., temperature, mode, etc.) and to receive operation commands. The display module 4 needs to be electrically connected to the control board in the electrical box 3 via a conductive wire 43 to receive operating data from the control board and simultaneously feed back user operation commands to the control board. By positioning the display module 4 on the side of the heat exchanger 2 near the electrical box 3 along the length of the casing 1, the length of the conductive wire 43 connecting the two can be shortened, thereby reducing interference and attenuation during signal transmission and improving command response speed.

[0096] In some embodiments, the display module 4 includes a housing 41, a circuit board 42, and conductive wires 43. The housing 41 has an internal mounting space 411. The housing 41 has a second wiring port 4121 communicating with the mounting space 411. Along the height of the housing 1, the second wiring port 4121 is located below the first wiring port 32. The circuit board 42 is disposed within the mounting space 411. One end of the conductive wire 43 passes through the first wiring port 32 to be electrically connected to the control motherboard, and the other end of the conductive wire 43 passes through the second wiring port 4121 to extend into the mounting space 411 and be electrically connected to the circuit board 42. The independent mounting space 411 within the housing 41 allows the circuit board 42 to communicate with the outside through the second wiring port 4121. This semi-enclosed structure directly prevents dust, lint, and other impurities in the indoor unit cavity 11 from adhering to the circuit board 42, avoiding short circuits or signal interference caused by foreign object accumulation, thereby extending the service life of the display module 4.

[0097] In some embodiments, the housing 41 includes a main housing 412 and an extended housing 413. The main housing 412 forms an installation space 411 and has a second wiring port 4121. The extended housing 413 is connected to one side of the main housing 412 and is at least partially disposed corresponding to the second wiring port 4121. A water-blocking channel 44 is formed between the extended housing 413 and the main housing 412. The water-blocking channel 44 includes a first sub-channel 441 and a second sub-channel 442. The first sub-channel 441 has a first opening 4411, which is configured to allow the other end of the conductive wire 43 to pass through and enter the first sub-channel 441. The opening direction of the first opening 4411 is different from the opening direction of the second wiring port 4121. The second sub-channel 442 communicates with the first sub-channel 441 and the second wiring port 4121. Along the height direction of the housing 1, the connection between the second sub-channel 442 and the first sub-channel 441 is located above the first opening 4411 and the second wiring port 4121. The second sub-channel 442 is configured to allow the other end of the conductive wire 43 to pass through to enter the second wiring port 4121 and connect to the circuit board 42.

[0098] The air conditioner 200 disclosed in this application comprises a main housing 412 and an outer housing 413 within the housing 41 of the display module 4. The main housing 412 forms an installation space 411 for placing a circuit board 42, and has a second wiring port 4121. The outer housing 413 is connected to one side of the main housing 412 and at least partially corresponds to the second wiring port 4121. A water-blocking channel 44 is formed between the outer housing 413 and the main housing 412. The first opening 4411 for the conductive wire 43 to enter the water-blocking channel 44 has a different opening direction than the second wiring port 4121 for the conductive wire 43 to enter the installation space 411. Thus, when the conductive wire 43 passes through the first sub-channel 441 and the second sub-channel 442 to extend into the installation space 411, it needs to be turned and cannot extend directly into it in a straight line. Meanwhile, along the height direction of the housing 1, the connection point between the second sub-channels 442 and the second wiring port 4121 is located above the first opening 4411 and the second wiring port 4121, so that the conductive wire 43 forms an upward and then downward trajectory in the water-blocking channel 44. In this way, when condensation occurs on the surface of the conductive wire 43, the water will naturally gather to the lower place under the action of gravity and will not be able to overcome gravity to flow from the first sub-channel 441 into the second sub-channel 442, thereby blocking the condensation generated on the conductive wire 43 outside the installation space 411 and preventing the condensation from flowing into the installation space 411 and causing malfunctions to the circuit of the display module 4.

[0099] It is understood that the main shell 412 and the outer shell 413 can be constructed as a single structure by integral molding, or they can be manufactured separately and then connected together. This embodiment does not specifically limit this.

[0100] Optionally, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of a water-blocking part provided in an embodiment of this application. Figure 6 This is another structural schematic diagram of the water-blocking part provided in the embodiment of this application. The main housing 412 is provided with a water-blocking part 4122 protruding toward the outer housing 413 near the second wiring port 4121, and a water-blocking channel 44 is formed between the water-blocking part 4122 and the outer housing 413.

[0101] Since the conductive wire 43 is usually quite flexible, in order to ensure that the conductive wire 43 can form an upward and then downward path in the water-blocking channel 44 as described above, a water-blocking part 4122 protruding towards the outer shell 413 is provided on the main housing 412. In this way, the water-blocking channel 44 can be formed through the gap between the water-blocking part 4122 and the outer shell 413, thereby ensuring the accuracy of the conductive wire 43's path and preventing the condensate from entering the interior of the display module 4 during long-term use of the air conditioner 200 due to changes in the path of the conductive wire 43, which would affect its normal use.

[0102] It is understood that the water-blocking part 4122 and the main shell 412 can be integrally formed, or they can be manufactured separately and then connected together. This embodiment does not make specific limitations on this.

[0103] It is understood that the aforementioned water-blocking part 4122 can be a solid boss, or it can be a hollow boss. This embodiment does not make any specific limitation on this.

[0104] In some embodiments, the water-blocking portion 4122 includes a water-guiding surface 41221. The water-guiding surface 41221 is disposed adjacent to the first opening 4411 and is inclined so that the width of the water-blocking portion 4122 along the length direction of the housing 1 gradually increases from the outer housing 413 to the main housing 412. The water-guiding surface 41221 is used to guide the water flow on the conductive wire 43 toward the side of the main housing 412 away from the second wiring opening 4121.

[0105] The water-blocking part 4122 includes a water-guiding surface 41221, which is located near the first opening 4411 and is inclined so that the width of the water-blocking part 4122 along the length of the housing 1 gradually increases from the outer housing 413 to the main housing 412. This allows the water-guiding surface 41221 to be inclined toward the side where the first opening 4411 is located. Therefore, when condensate on the surface of the conductive wire 43 enters the water-blocking channel 44 through the first opening 4411 due to high flow rate or large volume, the water-guiding surface 41221 will also change its flow trajectory by lateral guidance, thereby guiding the condensate along the water-guiding surface 41221 to the side of the main housing 412 away from the second wiring port 4121, preventing the condensate from reaching the connection between the first sub-channel 441 and the second sub-channel 442.

[0106] It is understandable that, such as Figure 6 As shown, the cross-sectional shape of the water-blocking part 4122 parallel to the front panel of the housing 1 can be a right-angled triangle, in which case the first sub-channel 441 is inclined and the second sub-channel 442 is vertically arranged. As shown, the cross-sectional shape of the water-blocking part 4122 parallel to the front panel of the housing 1 can also be a trapezoid, in which case the first sub-channel 441 is inclined, and the second sub-channel 442 includes a horizontal extension portion directly connected to the first sub-channel 441 and a vertical extension portion directly connected to the second wiring port 4121. This embodiment does not specifically limit this.

[0107] It should be noted that at the corner of the water-blocking part 4122, for example, when the cross-sectional shape of the water-blocking part 4122 parallel to the front panel of the housing 1 is a right triangle, a rounded corner is required at the junction of the water-blocking part 4122 and the first sub-channel 441 and the second sub-channel 442 to avoid scratching the conductive wire 43.

[0108] Please see Figures 7 to 10 , Figure 7 This is a schematic diagram of the structure of the first and second shells (excluding conductive wires) provided in the embodiments of this application. Figure 8 This is a schematic diagram of the structure of the second shell provided in an embodiment of this application. Figure 9 A top view of the second shell provided in an embodiment of this application. Figure 10 This is a schematic diagram of the structure of the first and second shells (excluding conductive wires) provided in an embodiment of this application. In some embodiments, the main shell 412 includes a first shell 4123 and a second shell 4124. The first shell 4123 has a top surface 41231, a second wiring port 4121 is disposed on the top surface 41231, and an extended shell 413 is connected to the top surface 41231. The first shell 4123 covers the second shell 4124, and the second shell 4124 is provided with a guide groove 41241a. One end of the guide groove 41241a is connected to the top surface 41231 to guide condensate on the conductive wire 43 into the water.

[0109] A guide channel 41241a is provided on the second shell 4124, with one end of the guide channel 41241a connected to the top surface 41231. The top surface 41231 is the surface of the first shell 4123 where the second wiring port 4121 is located, thereby guiding the condensate on the conductive wire 43 into the guide channel 41241a. In this way, when the water-blocking channel 44 intercepts the condensate generated on the conductive wire 43, the condensate will accumulate on the top surface 41231. The guide channel 41241a can drain the condensate accumulated on the top surface 41231, thereby avoiding the risk of leakage due to excessive accumulation of condensate on the top surface 41231.

[0110] In addition, by setting the guide channel 41241a, the condensate water accumulated on the top surface 41231 can be directed in a specific direction. This ensures that the condensate water does not spread to the surroundings when it flows, thereby preventing the condensate water from flowing into other components and affecting the normal use of the indoor unit 100 of the air conditioner 200.

[0111] It is understood that the second housing 4124 may include an integrally formed mounting portion 41243 and a shielding portion 41244. The mounting portion 41243 is used to cover the first housing 4123, and the flow guide groove 41241a is also disposed within the mounting portion 41243. The shielding portion 41244 is used to cover the opening of the electrical box 3. By including the integrally formed mounting portion 41243 and shielding portion 41244 in the second housing 41244, with the mounting portion 41243 used to provide the flow guide groove 41241a and the shielding portion 41244 used to cover the opening of the electrical box 3, the production and installation difficulty of the air conditioner 200 can be simplified. Furthermore, the second housing 4124 simultaneously protects the electrical box 3 and guides the condensate water in the display module 4.

[0112] It is understandable that, such as Figure 9 As shown, along the depth direction of the shell 41, the depth of the guide groove 41241a is L1, and the thickness of the second shell 4124 is L2, satisfying: 0.5L2≤L1≤L2.

[0113] When L1 < 0.5L2, the guide channel 41241a will be too shallow and unable to guide a large amount of condensate. This will easily cause the condensate to overflow from the edge of the guide channel 41241a, resulting in damage to other components.

[0114] When 0.5L2≤L1≤L2, this ensures that the guide channel 41241a has a certain effective volume, guaranteeing its guiding effect and guiding rate, while also preventing the guide channel 41241a from being too deep and affecting the structural strength of the second shell 4124.

[0115] Optionally, the top surface 41231 of the first shell 4123 is inclined toward the guide channel 41241a to guide condensate into the guide channel 41241a.

[0116] By setting the top surface 41231 to be inclined toward the guide channel 41241a, the condensate water accumulated on the top surface 41231 can be quickly guided to the guide channel 41241a, thereby improving the discharge rate of condensate water and preventing water accumulation at the top surface 41231, which would then leak into the display module 4.

[0117] In some embodiments, the top surface 41231 of the first shell 4123 is provided with a water-blocking rib 41231a. Along the length direction of the shell 41, the water-blocking rib 41231a is adjacent to and spaced apart from the first opening 4411. The water-blocking rib 41231a is configured to block the flow of condensate from the first opening 4411 to the top surface 41231, so that the condensate flows into the guide groove 41241a.

[0118] By setting water-blocking ribs 41231a on the top surface 41231, and along the length of the housing 41, water-blocking ribs 41231a are adjacent to the first opening 4411 and spaced apart from the first opening 4411, so that water-blocking ribs 41231a and water-blocking channel 44 can form an enclosed barrier, so that the condensate on the conductive wire 43 can only accumulate in this area, thereby allowing the condensate to flow only into the guide groove 41241a, preventing the condensate from flowing and spreading randomly and entering other components, thus affecting the normal use of the air conditioner 200.

[0119] In some embodiments, the outer housing 413 is provided with a contact portion 4131 located at the first opening 4411. The contact portion 4131 is used to abut against the conductive wire 43 located outside the first opening 4411, so that at least a portion of the conductive wire 43 connected to the contact portion is bent to form a bent portion 431. The bent portion 431 is provided corresponding to the guide groove 41241a to guide the condensate on the conductive wire 43 into the guide groove 41241a.

[0120] An abutment portion 4131 is provided on the outer shell 413, and the abutment portion 4131 is located at the first opening 4411. It is used to abut the conductive wire 43 outside the first opening 4411, so that at least a portion of the conductive wire 43 connected to the abutment portion is bent to form a bent portion 431. The bent portion 431 is provided corresponding to the guide groove 41241a to guide the condensate on the conductive wire 43 into the guide groove 41241a. In this way, the abutment portion can make the conductive wire 43 form a preset bent portion 431, and the bent portion 431 at least partially corresponds to the guide groove 41241a. This allows the conductive wire 43 to form a V-shaped bend. The condensate on the conductive wire 43 will preferentially flow to the lowest end of the bent portion 431 under the action of gravity, and thus flow into the guide groove 41241a. Furthermore, the abutment part 4131 is used to abut the conductive wire 43 outside the first opening 4411. This is equivalent to first allowing the condensate on the conductive wire 43 to flow into the guide groove 41241a through the bending part 431 before the water blocking channel 44, thereby better preventing the condensate on the conductive wire 43 from flowing into the display module 4 along the conductive wire 43.

[0121] It is understood that the aforementioned abutment portion 4131 can be a separately provided abutment plate or abutment block, connected to the end of the outer shell 413 near the first opening 4411. Of course, the abutment can also be achieved directly through the end of the outer shell 413 near the first opening 4411, and this embodiment does not specifically limit this.

[0122] Please see Figures 10 to 12 , Figure 11 This is a schematic diagram of the internal structure of the cavity (excluding the first shell) provided in an embodiment of this application. Figure 12 for Figure 11 A partially enlarged schematic diagram at point A. In some embodiments, a mounting space 411 is formed inside the first housing 4123, and the circuit board 42 is disposed within the mounting space 411. The second housing 4124 includes a back plate 41241 and a side plate 41242. The first housing 4123 covers the back plate 41241, and the opening of the mounting space 411 faces away from the back plate 41241. A guide groove 41241a is formed on the back plate 41241. The side plate 41242 surrounds and connects to the edge of the back plate 41241 to surround the outer periphery of the first housing 4123.

[0123] An installation space 411 is formed inside the first housing 4123, and the circuit board 42 is disposed within the installation space 411. The second housing 4124 includes a back plate 41241, and the first housing 4123 covers the back plate 41241. The opening of the installation space 411 faces away from the back plate 41241, and a guide groove 41241a is provided on the back plate 41241. This makes the installation space 411 inside the first housing 4123 an independent semi-enclosed area, communicating with the outside only through the second wiring port 4121. This allows for physical isolation between the installation space 411 and the guide groove 41241a of the second housing 4124, preventing condensate from entering the installation space 411 when flowing inside the guide groove 41241a.

[0124] Secondly, the back plate 41241 can serve as a mounting base for the first shell 4123, providing a stable mounting surface for the first shell 4123, thereby enabling the guide groove 41241a to precisely align with the top surface 41231 of the first shell 4123.

[0125] In addition, the side plate 41242 surrounds and connects to the edge of the back plate 41241 to cover the outer periphery of the first shell 4123. This allows the second shell 4124 to provide all-round protection for the first shell 4123, preventing other components in the inner cavity 11 from colliding with the first shell 4123 due to vibration, thereby affecting the normal use of the display module 4.

[0126] Optionally, please refer to Figures 10 to 14 , Figure 13 This is a schematic diagram of the water receiving tray provided in an embodiment of this application. Figure 14 for Figure 13 A partial enlarged view at point B. The indoor unit 100 also includes a drip tray 5, which is connected to the casing 1 and is located below the heat exchanger 2 along the height direction of the casing 1. The drip tray 5 is configured to collect condensate flowing down from the heat exchanger 2. A drain outlet 41242a is provided on the side of the second casing 4124 near the heat exchanger 2, and is located below the first casing 4123 along the height direction of the casing 1. The drain outlet 41242a is provided with a notch corresponding to the drip tray 5 and connected to the drip tray 5 to discharge condensate into the drip tray 5.

[0127] By positioning the drain outlet 41242a below the first housing 4123 along the height of the housing 1, the condensate in the guide channel 41241a can flow naturally to the drain outlet 41242a by gravity, eliminating the need for additional power devices such as water pumps, thereby helping to improve the efficiency and stability of condensate discharge.

[0128] In addition, the water receiving tray 5 itself is a drainage component used to receive the condensate generated by the heat exchanger 2. By setting the drain port 41242a to correspond to and connect to the water receiving tray 5, the condensate of the display module 4 and the condensate of the heat exchanger 2 can be drained through the same water receiving tray 5 without the need for an additional separate drainage component, which helps to reduce the manufacturing cost of the air conditioner 200.

[0129] When the heat exchanger 2 is cooling, the temperature of the display module 4 is lower the closer it is to the heat exchanger 2, and the easier it is to generate condensate. As a result, the surface of the back plate 41241 of the second shell 4124 near the heat exchanger 2 is also more prone to condensate. By setting the drain port 41242a on the side of the second shell 4124 near the heat exchanger 2, the condensate can be discharged directly through the drain port 41242a without having to travel a long distance, thus preventing the condensate from spreading to the side away from the heat exchanger 2 and causing water to enter and damage other components.

[0130] It is understandable that the projection of the drain outlet 41242a onto the plane of the drip tray 5 should be located within the drip tray 5. This ensures that the condensate drained from the drain outlet 41242a can enter the drip tray 5, preventing the condensate from flowing to other locations in the inner cavity 11 and affecting the normal operation of the air conditioner 200.

[0131] Understandably, the drip tray 5 is usually connected to a drain pipe, so that the condensate collected in the drip tray 5 can be discharged from the indoor unit 100 through the drain pipe.

[0132] In some embodiments, along the length of the housing 1, the guide channel 41241a and the drain port 41242a are spaced apart, and the drain port 41242a is closer to the heat exchanger 2 than the guide channel 41241a. The surface of the second housing 4124 with the drain port 41242a is constructed as an inclined surface, and the guide channel 41241a extends to the inclined surface, which is configured to guide the condensate from the guide channel 41241a to the drain port 41242a.

[0133] The surface of the second shell 4124 with a drain outlet 41242a is constructed as an inclined surface, and the guide channel 41241a extends to the inclined surface. In this way, when the condensate in the guide channel 41241a flows into the inclined surface, it will flow rapidly towards the drain outlet 41242a under the action of the gravitational component force generated by the slope, thereby improving the efficiency of condensate drainage.

[0134] In addition, dust, lint and other impurities in the inner cavity 11 of the indoor unit 100 may enter the guide channel 41241a with the airflow. By setting the guide channel 41241a and the drain outlet 41242a at intervals along the length of the casing 1, a buffer area is formed between the guide channel 41241a and the drain outlet 41242a. In this way, the impurities mixed in the condensate will naturally settle in the buffer area and will not be able to enter the drain outlet 41242a with the water flow, thereby reducing the risk of blockage of the drain outlet 41242a.

[0135] Optionally, please refer to Figure 15 , Figure 15 This is a schematic diagram of the inclined surface of the second shell provided in an embodiment of this application. The angle α between the inclined surface and the width direction of the housing 1 satisfies: α ≥ 2°.

[0136] During actual installation, the indoor unit 100 of the air conditioner 200 is difficult to install perfectly horizontally due to factors such as wall flatness, mounting bracket precision, or operational errors. It typically exhibits a natural tilt of less than 2°. If the included angle α of the inclined surface of the second shell 4124 is less than 2°, when the installation tilt direction of the indoor unit of the air conditioner 200 is opposite to the flow direction of the inclined surface, the two tilt angles will cancel each other out. This causes the actual flow slope of the inclined surface to approach 0°, and the condensate loses the driving force of gravity on the inclined surface, preventing it from flowing quickly to the drain outlet 41242a, and even leading to water accumulation. By setting the included angle α to ≥ 2°, it can be ensured that even after adding an installation tilt error of less than 2°, the inclined surface can still retain an effective flow slope of at least 0°. This allows the condensate to always flow directionally to the drain outlet 41242a under the action of gravity, preventing the flow guidance function from failing due to installation deviations of the indoor unit 100.

[0137] Please see Figure 16 and Figure 17 , Figure 16 This is a side view of the water receiving tray provided in an embodiment of this application. Figure 17 for Figure 16A partial enlarged view at point C. In some embodiments, the second housing 4124 is further provided with two guide portions 41245, both of which are located on the side of the second housing 4124 where the drain outlet 41242a is provided, and along the height direction of the housing 1, the guide portions 41245 are located below the drain outlet 41242a. Along the length direction of the housing 1, the two guide portions 41245 are respectively located on both sides of the opening of the drain outlet 41242a. Along the depth direction of the housing 1, the guide portion 41245 includes a first end 41245a and a second end 41245b. The first end 41245a is disposed away from the housing 1, and the second end 41245b is disposed opposite to the first end 41245a. The second end 41245b is constructed as an inclined end so that the width of the guide portion 41245 along the depth direction of the housing 1 gradually decreases from the second housing 4124 towards the drain outlet 41242a, so as to guide the condensate water to flow to the water receiving tray 5.

[0138] The guide section 41245 forms a tapering shape that gradually narrows from top to bottom along the depth direction of the casing 1. This allows condensate to flow from the drain outlet 41242a, guiding it towards the narrower end of the tapering section 41245, ultimately dripping into the drip tray 5 as a concentrated stream. This ensures that the condensate discharged from the drain outlet 41242a is more concentrated, preventing condensate from flowing outside the drip tray 5.

[0139] It is understood that the flow guide 41245 and the second shell 4124 can be integrally formed, or they can be manufactured separately and then connected together. This embodiment does not specifically limit this.

[0140] The air conditioner disclosed in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the air conditioner and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
