Description

Technical Field

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

[0002] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0003] The indoor unit of the air conditioner has a base inside the casing. The base forms a water collection trough below the heat exchanger. The water collection trough can collect the condensate dripping from the heat exchanger and then discharge it to the outside through the drain pipe, preventing the condensate from flowing around and affecting the operation of electrical components.

[0004] However, after long-term use, due to lack of cleaning and maintenance, dust, debris and other garbage can clog the drain pipe of an air conditioner, causing condensate to accumulate in the water tank and not drain smoothly. After a certain period of time, the condensate will overflow from the water tank. The overflowing condensate flows around irregularly and may come into contact with the electrical components inside the casing, causing short circuits. This can directly lead to the user being unable to use the air conditioner or even serious accidents such as electric leakage. Utility Model Content

[0005] This application discloses an indoor air conditioner unit that can collect condensate water when it is about to overflow from the water collection tray and discharge it into the room, reminding the user to maintain the indoor air conditioner unit.

[0006] To achieve the above objectives, this application discloses an indoor air conditioner unit, comprising: a casing, wherein the casing is provided with a casing air inlet and a casing air outlet, and a casing receiving cavity is formed within the casing, wherein the casing receiving cavity is provided with:

[0007] A base, wherein a heat exchange air duct is formed within the base;

[0008] A heat exchanger for exchanging heat with the airflow passing through the air inlet of the housing;

[0009] A cross-flow fan is installed in the heat exchange duct. The cross-flow fan is used to introduce airflow into the housing through the housing air inlet, and after heat exchange by the heat exchanger, it is delivered to the room through the housing air outlet.

[0010] A drive motor is disposed above the base, and the drive motor is used to drive the cross-flow fan to rotate;

[0011] The base also has the following features:

[0012] A water collection tank, located below the heat exchanger, is used to collect condensate. The bottom of the water collection tank has an outlet for connecting to the outside environment. The water collection tank has the following features:

[0013] The first channel wall is located near the air outlet of the housing, and the top of the first channel wall has an overflow notch;

[0014] A water guide channel is located on the side of the first channel wall away from the water receiving channel. The water guide channel is used to guide the condensate overflowing from the overflow gap to the air outlet of the casing so that the condensate enters the room through the air outlet of the casing.

[0015] In this way, the condensate overflowing from the overflow gap can be directly discharged through the air outlet of the casing, reducing the risk of condensate leakage, protecting the internal structure of the indoor unit of the air conditioner, and preventing condensate from flowing around in the casing cavity and coming into contact with electrical components, which could cause the electrical components to short-circuit due to water contact.

[0016] As an optional implementation, the water guide channel has:

[0017] The water outlet is located along the axial direction of the cross-flow fan on the side of the water guide groove near the air outlet of the housing, and is connected to the air outlet of the housing.

[0018] The lowest point of the tank bottom is located at the water outlet.

[0019] In this way, when viewed from the front and back of the unit casing, the blades of the cross-flow fan and the outlet of the water guide are not spaced apart. This allows the airflow generated by the fan blades to directly carry away the condensate at the outlet, causing it to be lifted by the airflow and significantly reducing the amount of condensate flowing downwards due to gravity. This prevents condensate from flowing downwards and staining the walls, and also allows the lifted condensate to fall directly near the user when they are not observing the condensate flow, providing a better and more effective reminder for the user to maintain the indoor unit.

[0020] As an optional implementation, the plane where the water outlet is located is flush with the end face of the blades of the cross-flow fan along the front-rear direction of the housing, or the projection of the plane where the water outlet is located along the front-rear direction of the housing is located on the blades of the cross-flow fan.

[0021] In this way, the lowest point of the first guide surface is located at the water outlet, so that after the condensate enters the water guide channel, it can move to the water outlet under the action of the first guide surface, so that the condensate can quickly enter the room from the air outlet of the casing, avoiding the accumulation of condensate in the casing and its flow everywhere, which could cause electrical components to short-circuit due to water contact.

[0022] As an optional implementation, the bottom of the tank has:

[0023] The first guide surface is inclined, and the outlet is located at the lowest point of the first guide surface.

[0024] In this way, after the condensate overflows from the overflow notch, it can flow from the first guide surface to the second guide surface under the action of gravity, and finally enter the air outlet of the casing from the second guide surface. Through this stepped guide surface design, it can move to the outlet under the action of the first guide surface, so that the condensate can quickly enter the room from the air outlet of the casing, avoiding the accumulation of condensate in the casing and its flow everywhere, which could cause electrical components to short-circuit due to water contact.

[0025] As an optional implementation, the bottom of the tank has:

[0026] First guide surface;

[0027] The second guide surface is arranged side by side with the first guide surface along the axial direction of the cross-flow fan, and the end face of the second guide surface is lower than the end face of the first guide surface. The water outlet is located at the end of the second guide surface away from the first guide surface.

[0028] In this way, after the condensate overflows from the overflow notch, it can flow from the first guide surface to the second guide surface under the action of gravity, and finally enter the air outlet of the casing from the second guide surface. Through this stepped guide surface design, it can move to the outlet under the action of the first guide surface, so that the condensate can quickly enter the room from the air outlet of the casing, avoiding the accumulation of condensate in the casing and its flow everywhere, which could cause electrical components to short-circuit due to water contact.

[0029] As an optional implementation, along the vertical direction of the housing, the end of the first guide surface near the second guide surface is aligned with the end face of the overflow notch near the cross-flow fan.

[0030] This reduces the height difference between the overflow notch and the bottom of the tank, preventing excessive height difference between the overflow notch and the bottom of the tank when condensate overflows, which could cause condensate to drip and splash, potentially hitting other parts and contacting electrical components, or generating significant water droplet noise and affecting the user experience.

[0031] As an optional implementation, the bottom of the tank has:

[0032] The third guide surface is arranged side by side with the second guide surface along the front-rear direction of the housing. The third guide surface is inclined and along the front-rear direction of the housing. One end of the second guide surface is connected to the end face of the first tank wall facing away from the water receiving tank, and the other end is connected to the lowest end of the third guide surface.

[0033] In this way, the condensate on the surface of the third guide surface can flow to the second guide surface, making the cross-section of the second guide surface that finally connects to the air outlet of the casing smaller. This allows the condensate to be more concentrated when it flows to the air outlet of the casing, which helps users to detect condensate overflow in time and maintain the indoor unit of the air conditioner promptly.

[0034] As an optional implementation, the second guide surface is inclined, and the connection end between the second guide surface and the third guide surface is the lowest end.

[0035] In this way, the second and third guide surfaces can form a water outlet with a cross-section roughly in the shape of a "V", which allows the condensate to be more concentrated. The lowest end of the "V"-shaped water outlet is discharged to the air outlet of the casing, which helps users to detect condensate overflow in time and maintain the indoor unit of the air conditioner in a timely manner.

[0036] As an optional implementation, the water guide channel further comprises:

[0037] The second groove wall is disposed opposite to the first groove wall along the front-rear direction of the housing, and the side of the second groove wall facing away from the first groove wall has multiple reinforcing ribs.

[0038] This effectively improves the structural strength of the water guide channel, preventing damage during use due to the impact of condensate or vibration from air conditioning operation, which could lead to water leakage and affect the water guiding function of the channel.

[0039] As an optional implementation, the overflow notch is located below the drive motor.

[0040] Therefore, when the overflow notch is located below the drive motor, the condensate below the drive motor can be discharged in time, preventing condensate from contacting the drive motor and causing damage to the drive motor, thus affecting the normal operation of the indoor unit of the air conditioner.

[0041] Compared with the prior art, the beneficial effects of this application are:

[0042] The air conditioner indoor unit provided in this embodiment has a base with a water collection trough to collect condensate generated by the heat exchanger and discharge it outdoors through an outlet. Furthermore, the first wall of the water collection trough has an overflow notch. When the outlet is blocked, the condensate accumulates in the trough and overflows just before overflowing. Under gravity, the condensate flows to a guide channel, which guides it to the air outlet of the casing, where it is then discharged into the room. This structure not only promptly discharges overflowing condensate outside the casing cavity, preventing it from spreading and short-circuiting electrical components, but also alerts the user by centrally discharging the condensate into the room. Since the indoor environment is where users are active, this centralized discharge of condensate makes it easier for users to notice. When users see the indoor unit draining water, they can detect any abnormalities and perform timely maintenance. Furthermore, the condensate draining from the air outlet of the casing allows the condensate to splash out of the casing along with the airflow at the air outlet, making it easier for users to notice, and preventing a large amount of condensate from flowing from the base and casing to the wall and staining the wall.

Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0062] The indoor unit of the air conditioner has a base inside the casing. The base forms a water collection trough below the heat exchanger. The water collection trough can collect the condensate dripping from the heat exchanger and then discharge it to the outside through the drain pipe, preventing the condensate from flowing around and affecting the operation of electrical components.

[0063] However, after long-term use, due to lack of cleaning and maintenance, dust, debris and other garbage can clog the drain pipe of an air conditioner, causing condensate to accumulate in the water tank and not drain smoothly. After a certain period of time, the condensate will overflow from the water tank. The overflowing condensate flows around irregularly and may come into contact with the electrical components inside the casing, causing short circuits. This can directly lead to the user being unable to use the air conditioner or even serious accidents such as electric leakage.

[0064] Based on this, this application discloses an indoor air conditioner unit that can guide the condensate water when it is about to overflow the water collection tray and discharge it into the room, reminding the user to maintain the indoor air conditioner unit.

[0065] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0066] Please see Figure 1 , Figure 5 and Figure 6 , Figure 1 This is a schematic diagram of the structure of the air conditioner indoor unit 100 disclosed in the embodiments of this application. Figure 5 This is a schematic diagram of the structure of the base 20 disclosed in the embodiments of this application. Figure 6 The embodiments disclosed in this application Figure 5 An enlarged structural diagram at point A. This application discloses an indoor air conditioning unit 100, which includes a casing 10. The casing 10 has a casing air inlet 101 and a casing air outlet 102, and a casing receiving cavity 103 is formed inside the casing 10. The casing receiving cavity 103 is equipped with a base 20, a heat exchanger 30, a cross-flow fan 40, and a drive motor 50. A heat exchange duct 201 is formed inside the base 20. The heat exchanger 30 is used to exchange heat with the airflow flowing through the casing air inlet 101. The cross-flow fan 40 is disposed within the heat exchange duct 201 and is used to introduce airflow from the casing air inlet 101 into the casing 10, and after heat exchange by the heat exchanger 30, it is delivered to the room through the casing air outlet 102. The drive motor 50 is disposed within the heat exchange duct 201. Above the base 20, the drive motor 50 drives the cross-flow fan 40 to rotate; the base 20 also forms a water receiving trough 21 and a water guiding trough 22. The water receiving trough 21 is located below the heat exchanger 30 and is used to collect condensate. The bottom of the water receiving trough 21 has a water outlet 221 for connecting to the outside. The water receiving trough 21 has a first trough wall 211, which is located near the air outlet 102 of the casing. The top of the first trough wall 211 has an overflow notch 2111. The water guiding trough 22 is located on the side of the first trough wall 211 away from the water receiving trough 21. The water guiding trough 22 is used to guide the condensate overflowing from the overflow notch 2111 to the air outlet 102 of the casing so that the condensate enters the room from the air outlet 102 of the casing.

[0067] Combination Figure 1 The air conditioner indoor unit 100 proposed in this application includes a housing 10, the housing 10 is provided with a housing air inlet 101 and a housing air outlet 102, and a housing receiving cavity 103 is formed inside the housing 10.

[0068] In some embodiments, combined with Figure 2 and Figure 3 , Figure 2 This is a schematic cross-sectional view of the indoor unit 100 of the air conditioner disclosed in an embodiment of this application. Figure 3 This is a schematic diagram of the indoor unit 100 of the air conditioner disclosed in this application, omitting the casing 10 and some internal structures. A heat exchanger 30 is provided within the casing cavity 103. The heat exchanger 30 is used to exchange heat with the airflow passing through the air inlet 101 of the casing. When the air conditioner is cooling, the low-temperature refrigerant flowing within the heat exchanger 30 absorbs heat from the airflow, thus cooling the air. When heating, the high-temperature refrigerant releases heat to the airflow, thus warming the air. The heat exchanger 30 typically adopts a finned structure to increase the contact area with the airflow, improve heat exchange efficiency, and ensure that the air entering the room reaches the set temperature.

[0069] In some embodiments, combined with Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of the base 20, cross-flow fan 40, and drive motor 50 disclosed in this application embodiment. The cross-flow fan 40 is provided in the housing cavity 103. The cross-flow fan 40 is used to introduce airflow into the housing 10 through the housing air inlet 101, and after heat exchange by the heat exchanger 30, it is delivered to the room through the housing air outlet 102. When working, the cross-flow fan 40 generates negative pressure by rotating, which draws indoor air in from the housing air inlet 101. After heat exchange by the heat exchanger 30, the processed air is then delivered into the room through the housing air outlet 102 by the thrust of the fan, completing the circulation and renewal of indoor air.

[0070] In some embodiments, combined with Figure 5 and Figure 6 The base 20 also forms a water collection trough 21, which can be formed by upward-protruding ribs of the base 20. The shape of the water collection trough 21 is not limited, but it is located below the heat exchanger 30. When condensate forms on the heat exchanger 30 and drips downwards, it can drip into the water collection trough 21. By collecting the condensate dripping from the heat exchanger 30 through the water collection trough 21, the condensate can be prevented from flowing around in the housing cavity 103 and from contacting the electrical components inside the housing cavity 103, which could cause the electrical components to short-circuit due to water.

[0071] In some embodiments, combined with Figure 6 The ribs that protrude upward from the base 20 to form the water receiving tank 21, one of which is the first tank wall 211 near the air outlet 102 of the housing. An overflow notch 2111 is provided at the top of the first tank wall 211. When condensate accumulates in the water receiving tank 21 and is about to overflow, it can preferentially flow out from the overflow notch 2111. The overflow notch 2111 can guide the condensate that is about to overflow, preventing the condensate from overflowing and flowing to various parts of the housing cavity 103, which would cause the electrical components in the housing cavity 103 to come into contact with the condensate and cause a short circuit.

[0072] Please see Figures 1 to 6In some embodiments, the front-to-back direction of the housing 10 is from the front panel to the back panel. The base 20 has a water guide groove 22 on the rear side of the first groove wall 211 along the front-to-back direction of the housing 10. The water guide groove 22 guides the condensate draining from the overflow notch 2111, allowing it to flow to the housing air outlet 102, so that the overflowing condensate can be discharged into the room from the housing air outlet 102. This arrangement prevents condensate from overflowing from the water collection trough 21 and flowing to various parts of the housing cavity 103, which could cause electrical components inside the housing cavity 103 to come into contact with the condensate and short-circuit. Because the condensate is concentrated and discharged into the room, users can also promptly detect abnormalities in the indoor unit 100 and perform timely maintenance, including repairing the water outlet 221 of the water collection trough 21, so that the condensate can be discharged normally to the outside through the water outlet 221, ensuring the normal working condition of the indoor unit 100. In addition, condensate enters the room through the air outlet 102 on the casing. When the indoor unit 100 is operating, the condensate can be quickly carried into the room by the airflow at the air outlet 102, making it easier for users to notice. This allows users to promptly detect any abnormalities in the indoor unit 100 and perform timely maintenance and repairs via the drain outlet 221 of the water tank 21. Furthermore, the airflow carrying the condensate into the room prevents it from flowing downwards along the base 20 and casing 10, thus avoiding wall contamination.

[0073] According to an embodiment of the present invention, the indoor unit 100 of the air conditioner has a base 20 with a water collection trough 21 for collecting condensate from the heat exchanger 30 and discharging it outdoors through the outlet 221. Furthermore, the first wall 211 of the water collection trough 21 has an overflow notch 2111. When the outlet 221 is blocked, the condensate accumulates in the water collection trough 21 and overflows from the overflow notch 2111 when it is about to overflow. Under gravity, the condensate flows to the guide channel, which guides it to the air outlet 102 of the casing, where it is then discharged into the room. This structure not only promptly discharges overflowing condensate outside the casing cavity 103, preventing condensate from overflowing and causing short circuits in the electrical components within the casing cavity 103, but also alerts the user by centrally discharging the condensate into the room. Since the indoor environment is where users spend most of their time, directing condensate water indoors makes it easier for users to notice. When users see the indoor unit 100 draining water, they can detect any abnormality and perform timely maintenance. Furthermore, discharging condensate water through the air outlet 102 allows it to splash out of the casing 10 along with the airflow, making it easier for users to spot. This also prevents large amounts of condensate water from flowing from the base 20 and casing 10 onto the wall, thus avoiding wall contamination.

[0074] Combination Figure 5 and Figure 6 In some embodiments, the water guide channel 22 has a water outlet 221 and a channel bottom 222. The water outlet 221 is arranged along the axial direction of the cross-flow fan 40 on the side of the water guide channel 22 near the air outlet 102 of the housing and is connected to the air outlet 102 of the housing. The lowest point of the channel bottom 222 is located at the water outlet 221.

[0075] Specifically, the top of the water guide channel 22 corresponds to the overflow notch 2111, allowing water overflowing from the overflow notch 2111 to enter the water guide channel 22. The bottom 222 of the water guide channel 22 can be designed in different shapes, such as flat, curved, trapezoidal, or other complex shapes, but the lowest point of the bottom 222 is located at the outlet 221, guiding the condensate entering the water guide channel 22 towards the outlet 221, and from the outlet 221 into the air outlet 102 of the casing. The water guide channel 22 can be made of different materials, such as plastic, metal, or composite materials, as long as they meet the requirements of structural strength and water guiding performance. Because a water guide channel 22 is provided, and the outlet 221 of the water guide channel 22 is connected to the air outlet 102 of the casing, the condensate overflowing from the overflow gap 2111 can be directly discharged through the air outlet 102 of the casing, reducing the risk of condensate leakage, protecting the internal structure of the air conditioner indoor unit 100, and preventing condensate from flowing around in the casing cavity 103 and coming into contact with electrical components, which could cause the electrical components to short-circuit due to water contact.

[0076] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments, the plane where the water outlet 221 is located is flush with the end face of the blades of the cross-flow fan 40 along the front-rear direction of the housing 10, or the projection of the plane where the water outlet 221 is located along the front-rear direction of the housing 10 is located on the blades of the cross-flow fan 40.

[0077] Specifically, the position of the water outlet 221 and the position of the cross-flow fan 40 are not limited. The water outlet 221 can be positioned flush with or overlapping the blades of the cross-flow fan 40 along the front-back direction of the casing 10. That is, when viewed from the front-back direction of the casing 10, the blades of the cross-flow fan 40 and the water outlet 221 of the water guide 22 are not spaced apart. This allows the airflow generated by the blades of the cross-flow fan 40 to directly carry away the condensate at the water outlet 221, causing the condensate to be lifted by the airflow, significantly reducing the condensate flowing downwards due to gravity. This prevents condensate from flowing downwards and staining the walls, and when the user does not observe the condensate flow, the lifted condensate directly falls near the user, providing a better and more effective reminder for the user to maintain the indoor unit 100.

[0078] Combination Figure 5In some embodiments, the bottom of the tank 222 has a first guide surface 2221, the first guide surface 2221 is inclined, and the outlet 221 is located at the lowest point of the first guide surface 2221.

[0079] Specifically, the shape of the bottom 222 of the tank is not limited, and an inclined first guide surface 2221 can be set on the bottom 222 of the tank. The lowest point of the first guide surface 2221 is located at the outlet 221, so that after the condensate enters the water guide tank 22, it can move to the outlet 221 under the action of the first guide surface 2221, so that the condensate can quickly enter the room from the air outlet 102 of the casing, avoiding the accumulation of condensate in the casing 10 and its flow everywhere, which could cause electrical components to short-circuit due to water contact.

[0080] Combination Figure 7 and Figure 8 , Figure 7 This is a schematic cross-sectional view of the base 20 disclosed in an embodiment of this application. Figure 8 The embodiments disclosed in this application Figure 7 Enlarged structural schematic diagram at point B. In some embodiments, the tank bottom 222 has a first guide surface 2221; the second guide surface 2222 and the first guide surface 2221 are arranged side by side along the axial direction of the cross-flow fan 40, and the end face of the second guide surface 2222 is lower than the end face of the first guide surface 2221, and the outlet 221 is located at the end of the second guide surface 2222 away from the first guide surface 2221.

[0081] Specifically, the shape of the bottom 222 is not limited, and two guide surfaces can be provided, namely the first guide surface 2221 and the second guide surface 2222. The first guide surface 2221 and the second guide surface 2222 are generally stepped. The end face of the second guide surface 2222 near the outlet 221 is lower than the end face of the first guide surface 2221. This allows the condensate to overflow from the overflow gap 2111 and flow from the first guide surface 2221 to the second guide surface 2222 under the action of gravity. Finally, it enters the air outlet 102 of the casing from the second guide surface 2222. Through this stepped guide surface design, the condensate can move to the outlet 221 under the action of the first guide surface 2221, so that the condensate can quickly enter the room from the air outlet 102 of the casing. This prevents the condensate from accumulating in the casing 10 and flowing around, which could cause electrical components to short-circuit due to water contact.

In some embodiments, along the vertical direction of the housing 10, the end of the first guide surface 2221 near the second guide surface 2222 is aligned with the end face of the overflow notch 2111 near the cross-flow fan 40.

[0083] Specifically, the overflow notch 2111 can correspond partly to the first guide surface 2221 and partly to the second guide surface 2222, or it can correspond completely to the first guide surface 2221 (i.e., the end of the first guide surface 2221 near the second guide surface 2222 is flush with the end face of the overflow notch 2111 near the cross-flow fan 40). This can reduce the height difference between the overflow notch 2111 and the bottom of the tank 222, and prevent the height difference between the overflow notch 2111 and the bottom of the tank 222 from being too high when the condensate overflows from the overflow notch 2111, which would cause the condensate to drip and splash, splash to other positions and come into contact with electrical components, or generate a lot of water droplet noise, affecting the user experience.

[0084] Combination Figure 9 and Figure 10 In some embodiments, the bottom of the tank 222 has a third guide surface 2223. The third guide surface 2223 and the second guide surface 2222 are arranged side by side along the front and rear direction of the housing 10. The third guide surface 2223 is inclined and along the front and rear direction of the housing 10. One end of the second guide surface 2222 is connected to the end face of the first tank wall 211 facing away from the water receiving tank 21, and the other end is connected to the lowest end of the third guide surface 2223.

[0085] Specifically, the shape of the bottom 222 is not limited, and three guide surfaces can be provided, namely the first guide surface 2221, the second guide surface 2222, and the third guide surface 2223. The second guide surface 2222 and the third guide surface 2223 are arranged side by side with the first guide surface 2221 along the axial direction of the cross-flow fan 40. The third guide surface 2223 is arranged side by side with the second guide surface 2222 along the front-back direction of the casing 10. The third guide surface 2223 is inclined so that the condensate on the surface of the third guide surface 2223 can flow to the second guide surface 2222. This makes the cross section of the second guide surface 2222 that finally connects with the air outlet 102 of the casing smaller, so that the condensate can be more concentrated when it flows to the air outlet 102 of the casing. This is beneficial for users to detect the overflow of condensate in time and maintain the indoor unit 100 of the air conditioner in a timely manner.

[0086] Combination Figure 5 In some embodiments, the second guide surface 2222 is inclined, and the connection end between the second guide surface 2222 and the third guide surface 2223 is the lowest end.

[0087] Specifically, the second guide surface 2222 can be set horizontally or inclined, and the connection end between the second guide surface 2222 and the third guide surface 2223 is the lowest end, so that the second guide surface 2222 and the third guide surface 2223 form a water outlet 221 with a cross-section of approximately "V" shape, so that the condensate can be more concentrated and discharged to the air outlet 102 of the casing from the lowest end of the "V" shaped water outlet 221. This helps users to detect the overflow of condensate in time and maintain the indoor unit 100 of the air conditioner in a timely manner.

[0088] Combination Figure 6 In some embodiments, the water guide channel 22 also has a second channel wall 223, which is arranged opposite to the first channel wall 211 along the front-rear direction of the housing 10. The side of the second channel wall 223 facing away from the first channel wall 211 has a plurality of reinforcing ribs 224.

[0089] Specifically, the water guiding channel 22 can be formed by upward-protruding ribs from the base 20. Opposite to the first channel wall 211 is the second channel wall 223 of the water guiding channel 22. Only the second channel wall 223 can be provided, or multiple reinforcing ribs 224 can be provided on the side of the second channel wall 223 facing away from the first channel wall 211. The number of reinforcing ribs 224 can be up to five, depending on the design requirements. The reinforcing ribs 224 can be designed in different shapes, such as triangles, rectangles, or trapezoids, as long as they provide sufficient structural strength. The reinforcing ribs 224 can extend from the second channel wall 223 to the body of the base 20, ensuring the effectiveness of the reinforcing ribs 224 and improving the connection strength between the second channel wall 223 and the body of the base 20. The reinforcing ribs 224 effectively improve the structural strength of the water guiding channel 22, preventing damage during use due to the impact of condensate or vibration from air conditioning operation, which could lead to leakage and affect the water guiding function of the water guiding channel 22.

[0090] Combination Figure 4 , Figure 5 and Figure 6 In some embodiments, the overflow notch 2111 is located below the drive motor 50.

[0091] Specifically, the overflow notch 2111 can be located at one end away from the drive motor 50, or at various locations on the first groove wall 211. Setting the overflow notch 2111 below the drive motor 50 not only avoids damaging the integrity of other parts of the first groove wall 211 and avoids affecting the volute tongue setting on the first groove wall 211, but also protects the drive motor 50. The drive motor 50 is a relatively important electrical component of the air conditioner indoor unit 100. When the overflow notch 2111 is located below the drive motor 50, the condensate below the drive motor 50 can be discharged in time, preventing condensate from contacting the drive motor 50 and causing damage to the drive motor 50, thus affecting the normal operation of the air conditioner indoor unit 100.
