Description

Technical Field

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

[0002] In related technologies, the chassis component of an air conditioner is used to install and support heat exchanger assemblies and fan assemblies. A water collection trough is formed on the chassis component to collect condensate.

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] The following is for reference. Figures 1-12 An air conditioner according to an embodiment of the present invention is described. Wherein, Figure 6 , Figure 8 , Figure 10 and Figure 12 The arrows in the diagram indicate the direction of water flow.

[0050] Reference Figures 1-4 An air conditioner according to an embodiment of the present invention includes: a housing assembly 101, a heat exchanger assembly 40, and a fan assembly 50.

[0051] The housing assembly 101 has an air inlet and an air outlet 10. For example, the housing assembly 101 includes a front housing component and a rear housing component, with the air outlet 10 formed on the front housing component and the air inlet formed on the rear housing component. When the air conditioner is working, airflow enters the air conditioner through the air inlet, passes through the heat exchanger assembly 40 and exchanges heat with the heat exchanger assembly 40, passes through the fan assembly 50 driven by the impeller 51, and leaves the air conditioner through the air outlet 10, blowing it into the room, thereby regulating the indoor temperature.

[0052] The housing assembly 101 includes a chassis component 11 for supporting and mounting the heat exchanger assembly 40 and the fan assembly 50. The heat exchanger assembly 40 is located within the housing assembly 101 and mounted on the chassis component 11, and can be supported on the chassis component 11. The fan assembly 50 is located within the housing assembly 101 and mounted on the chassis component 11. For example, the fan assembly 50 includes a fan impeller 51.

[0053] A water receiving trough 12 is formed on the chassis component 11 to collect condensate flowing down from the heat exchanger assembly 40. The water receiving trough 12 includes a first water receiving area 13 and a second water receiving area 15, with the second water receiving area 15 being lower than the first water receiving area 13. By making the second water receiving area 15 lower than the first water receiving area 13, water in the first water receiving area 13 can flow downward into the second water receiving area 15, thereby causing the water in the water receiving trough 12 to collect in the lower-positioned second water receiving area 15. The water in the second water receiving area 15 can be discharged through a drain pipe.

[0054] A diversion channel 17 is formed on the bottom wall of the water receiving tank 12, extending from the first water receiving area 13 to the second water receiving area 15. For example, the diversion channel 17 includes an inlet end 18 and an outlet end 19. The inlet end 18 is located in the first water receiving area 13, and the outlet end 19 is located in the second water receiving area 15. Water in the first water receiving area 13 can flow into the diversion channel through the inlet end 18 and into the diversion channel. Guided by the diversion channel, it flows downward to the outlet end 19, thereby diverting the water in the first water receiving area 13 to the second water receiving area 15. By providing the diversion channel, the water in the first water receiving area 13 can easily flow to the second water receiving area 15 under the guidance of the diversion channel, thereby reducing water accumulation in the first water receiving area 13 and lowering the risk of overflow due to excessive water accumulation.

[0055] The air conditioner can be a split-type air conditioner, such as a split wall-mounted air conditioner. The air conditioner can include an indoor unit 100 and an outdoor unit. The indoor unit 100 includes the aforementioned casing assembly 101, heat exchanger assembly 40, and fan assembly 50. When the air conditioner is a split wall-mounted air conditioner, the indoor unit 100 is horizontally mounted on the wall. The air inlet is formed at the top of the casing assembly 101, and the air outlet 10 is formed at the lower front part of the casing assembly 101. The water collection tray 12 can be located in front of the impeller 51, and the first water collection area 13 can be located in front of the second water collection area 15. The impeller 51 of the fan assembly 50 can be a cross-flow impeller 51.

[0056] For example, the air conditioner also includes an insulating foam component 32, which is located below the first water receiving area 13 and covers the outer wall surface of the first water receiving area 13. The insulating foam component 32 can insulate the outer wall surface of the first water receiving area 13, preventing condensation from forming on the outer wall surface of the first water receiving area 13.

[0057] According to an embodiment of the present invention, an air conditioner is provided with a drainage channel 17 on the bottom wall of the water receiving tank 12, and the drainage channel 17 extends from the first water receiving area 13 to the second water receiving area 15. This allows water in the first water receiving area 13 to flow downward into the second water receiving area 15 under its own gravity through the drainage channel 17. As a result, the water in the first water receiving area 13 can easily flow downward into the second water receiving area 15 under the drainage effect of the drainage channel 17, thereby reducing the water accumulation in the first water receiving area 13 and reducing the risk of overflow caused by excessive water accumulation in the first water receiving area 13.

[0058] According to some embodiments of the present invention, with reference to Figure 6 The depth of the drainage channel 17 is b, and the value of b ranges from 5mm to 16mm. For example, the value of b can be 5mm, 7mm, 9mm, 12mm, 16mm, etc. By ensuring that the depth b of the drainage channel 17 is not less than 5mm, the drainage channel 17 can fully guide the water in the first water receiving area 13 into the second water receiving area 15, so that the water in the first water receiving area 13 can be discharged more smoothly. By ensuring that the depth b of the drainage channel 17 is not greater than 16mm, the structural strength of the chassis assembly can be avoided from being reduced due to the excessive depth of the opening of the drainage channel 17.

[0059] According to some embodiments of the present invention, with reference to Figure 6 and Figure 10 The drainage channel 17 is a groove formed on the bottom wall of the water receiving tank 12. By making the drainage channel 17 a groove formed on the bottom wall of the water receiving tank 12, the structure of the drainage channel 17 can be simplified and the manufacturing process can be made easier.

[0060] According to some embodiments of the present invention, with reference to Figure 10The diversion channel 17 includes an inlet end 18 and an outlet end 19. The inlet end 18 is located at the end of the first water receiving area 13 near the second water receiving area 15, and the outlet end 19 is located within the second water receiving area 15. By positioning the inlet end 18 of the diversion channel 17 at the end of the first water receiving area 13 near the second water receiving area 15 and the outlet end 19 within the second water receiving area 15, the diversion channel 17 can guide the water in the first water receiving area 13 to the second water receiving area 15, preventing excessive water in the first water receiving area 13 from overflowing.

[0061] According to some embodiments of the present invention, with reference to Figure 10 The diversion channel 17 includes an inlet end 18 and an outlet end 19. The inlet end 18 is located within the first water receiving area 13, and the outlet end 19 is located at the lowest position of the second water receiving area 15. By placing the inlet end 18 of the diversion channel 17 within the first water receiving area 13, water in the first water receiving area 13 can be more fully introduced into the diversion channel 17, making it easier to drain the water in the first water receiving area 13. By placing the outlet end 19 of the diversion channel 17 at the lowest position of the second water receiving area 15, the water in the first water receiving area 13 can be directly diverted downwards through the diversion channel 17 to the lowest position of the second water receiving area 15 through the diversion channel 17. This allows the water in the first water receiving area 13 to quickly gather at the lowest position of the second water receiving area 15, facilitating timely drainage of the water in both the first and second water receiving areas 13.

[0062] According to some embodiments of the present invention, with reference to Figure 9 and Figure 11 There are multiple drainage channels 17, which are spaced apart along the length of the water receiving trough 12. The length of the water receiving trough 12 is perpendicular to the arrangement direction of the first water receiving area 13 and the second water receiving area 15. By arranging multiple drainage channels 17 spaced apart along the length of the water receiving trough 12, water in the first water receiving area 13 can flow into the second water receiving area 15 through the drainage channels 17 along the length of the water receiving trough 12, thereby increasing the drainage speed of water in the first water receiving area 13 and more effectively preventing water overflow from the first water receiving area 13 due to excessive water.

[0063] According to some embodiments of the present invention, with reference to Figure 10A protruding structure 20 is provided on the bottom wall of the first water receiving area 13. The protruding structure 20 defines a flow outlet 28, which is located at the edge of the flow channel 17, so as to guide the water in the first water receiving area 13 to the flow channel 17. By providing a protruding structure 20 on the bottom wall of the first water receiving area 13, the protruding structure 20 can guide the water flow, causing the water in the first water receiving area 13 to flow along the edge of the protruding structure 20 when it approaches the protruding structure 20. The protruding structure 20 guides this part of the water flow to the diversion channel 17 and thus leaves the first water receiving area 13, allowing the water in the first water receiving area 13 to be discharged more quickly. Furthermore, the diversion port 28 defined by the protruding structure 20 can increase the shear force of the water when it flows through the diversion port 28, allowing the water in the first water receiving area 13 to be quickly diverted to the diversion channel 17 under the diversion effect of the diversion port 28, and then flow downward into the second water receiving area 15 through the diversion channel 17, thereby increasing the discharge speed of the water in the first water receiving area 13 and more effectively preventing the water in the first water receiving area 13 from overflowing.

[0064] When condensate is generated on the heat exchanger assembly 40, the condensate drips downwards into the first water receiving area 13 under its own gravity. The condensate flows in the first water receiving area 13 and is guided by the protruding structure 20 to the inlet 28. The surface tension of the water flowing through the inlet 28 decreases and the shear force increases, so the water flows faster and more easily into the inlet channel 17, and then flows to the second water receiving area 15.

[0065] According to some embodiments of the present invention, with reference to Figure 10 The width of the drain opening 28 is 'a', and the value of 'a' ranges from 3mm to 6mm. For example, the value of 'a' can be 3mm, 4mm, 5mm, 6mm, etc. By ensuring that the width 'a' of the drain opening 28 is not less than 3mm, the drain opening 28 has sufficient width to allow water to flow through, enabling the water in the first water receiving area 13 to flow smoothly into the second water receiving area 15 through the drain opening 28. By ensuring that the width 'a' of the drain opening 28 is not greater than 6mm, while ensuring that the water in the first water receiving area 13 can flow smoothly into the second water receiving area 15 through the drain hole, the opening of the drain opening 28 is relatively narrow, which more fully increases the shear force of the water and increases the flow velocity of the water when it flows through the drain opening 28.

[0066] According to some embodiments of the present invention, with reference to Figures 9-12 Each drainage channel 17 corresponds to at least one drainage port 28. When water flows through the drainage port 28, the shear force of the water can be increased. By making each drainage channel 17 correspond to at least one drainage port 28, the speed of water in the first water receiving area 13 when flowing into the drainage channel 17 can be increased, so that the water in the first water receiving area 13 can be discharged more quickly and efficiently, avoiding the overflow of water in the first water receiving area 13 due to excessive water.

[0067] According to some embodiments of the present invention, with reference to Figures 9-12 The raised structure 20 includes a sealing rib structure 21 and a flow-guiding boss 27. The bottom of the heat exchanger assembly 40 is supported on the sealing rib structure 21. The sealing rib structure 21 includes a first sealing rib 22 arranged along the length of the water receiving groove 12. The first sealing rib 22 is located at one end of the first water receiving area 13 near the second water receiving area 15. A portion of the flow-guiding groove 17 is formed on the first sealing rib 22. The flow-guiding boss 27 is located on the side of the first sealing rib 22 away from the second water receiving area 15. A flow-guiding port 28 is defined between the flow-guiding boss 27 and the first sealing rib 22. By including a sealing rib structure 21 in the protruding structure 20, the bottom of the heat exchanger assembly 40 is supported on the sealing rib structure 21. The sealing rib structure 21 can support the heat exchanger assembly 40 and improve the sealing performance between the heat exchanger assembly 40 and the chassis component 11, thus better preventing unheated airflow from passing between the heat exchanger assembly 40 and the chassis component 11. By forming part of the drainage groove 17 on the first sealing rib 22, the processing of the drainage groove 17 can be simplified, and the drainage groove 17 can more easily guide the water in the first water receiving area 13 to the second water receiving area 15. By positioning the drainage protrusion 27 on the side of the first sealing rib 22 away from the second water receiving area 15, a drainage port 28 is defined between the drainage protrusion 27 and the first sealing rib 22. This allows the drainage protrusion 27 to easily form a relatively narrow drainage port 28 with the first sealing rib 22. This ensures that the water in the first water receiving area 13 can flow smoothly into the second water receiving area 15 through the drainage hole, while also increasing the shear force of the water and improving the flow speed of the water when it flows through the drainage port 28.

[0068] According to some embodiments of the present invention, with reference to Figures 9-12 The end of the drainage channel 17 located in the first water receiving area 13 is the inlet end 18, and the drainage protrusion 27 is located on the side of the inlet end 18 away from the second water receiving area 15. By positioning the drainage protrusion 27 on the side of the inlet end 18 away from the second water receiving area 15, the drainage port 28 can be located on the side of the first water receiving area 13 closer to the second water receiving area 15, that is, the drainage port 28 is located on the side closer to the bottom, so that the water in the first water receiving area 13 can flow into the drainage channel 17 through the drainage port 28 under its own gravity, thus avoiding excessive water in the first water receiving area 13.

[0069] According to some embodiments of the present invention, with reference to Figures 9-12Multiple drainage channels 17 are provided, spaced apart along the length of the water receiving trough 12, which is perpendicular to the arrangement direction of the first water receiving area 13 and the second water receiving area 15. By spaced apart along the length of the water receiving trough 12, water in the first water receiving area 13 can flow into the second water receiving area 15 through the drainage channels 17, increasing the drainage speed of water in the first water receiving area 13 and more effectively preventing condensation from forming on the outer wall of the first water receiving area 13 due to excessive water.

[0070] Furthermore, there are multiple drainage protrusions 27, as shown in the reference. Figures 9-12 Multiple drainage protrusions 27 are spaced apart along the length of the water receiving trough 12. The number of drainage protrusions 27 is the same as the number of drainage channels 17 and they correspond one-to-one. Each drainage protrusion 27 defines at least one drainage port 28 between itself and the first sealing rib 22. By arranging multiple drainage protrusions 27 spaced apart along the length of the water receiving trough 12, and ensuring that the number of drainage protrusions 27 is the same as the number of drainage channels 17 and they correspond one-to-one, the water in the first water receiving area 13 can be better guided by the drainage protrusions 27 to flow to the drainage port 28 along the length of the water receiving trough 12. The water can then flow into the drainage channel 17 through the drainage port 28 and leave the first water receiving area 13, thus more effectively preventing water overflow from the first water receiving area 13 due to excessive water. By defining at least one drainage port 28 between each drainage protrusion 27 and the first sealing rib 22, water guided by the drainage protrusion 27 can flow to the drainage port 28 and be discharged from the first water receiving area 13, thus more effectively preventing excessive water in the first water receiving area 13 from overflowing.

[0071] According to some embodiments of the present invention, with reference to Figure 2 and Figure 3 The air conditioner includes an air outlet channel 30 formed within the housing assembly 101. The fan assembly 50 includes a fan wheel 51. The air outlet channel 30 is located between the fan wheel 51 and the air outlet 10. The air conditioner also includes a protective net 31, which is installed on the chassis assembly 11 and located within the air outlet channel 30. A positioning hole 29 for positioning the protective net 31 is formed on the back side of the air guide boss 27. By including the protective net 31 in the air conditioner, the protective net 31 can prevent the user's hand from being inserted into the air conditioner through the air outlet 10, thus preventing injury. By forming the positioning hole 29 for positioning the protective net 31 on the back side of the air guide boss 27, and because the water receiving groove 12 at the location of the air guide boss 27 is relatively thick, the connection between the protective net 31 and the water receiving groove 12 at this location is better. This makes the connection between the protective net 31 and the water receiving groove 12 more secure and more effectively prevents the protective net 31 from loosening and falling off.

[0072] According to some embodiments of the present invention, with reference to Figures 2-8 The first sealing rib 22 extends obliquely towards the second water receiving area 15 in a downward direction. By making the first sealing rib 22 extend obliquely towards the second water receiving area 15 in a downward direction, the condensate adhering to the first sealing rib 22 can flow downward along the first sealing rib 22 and towards the second water receiving area 15.

[0073] According to some embodiments of the present invention, with reference to Figures 9-12 The first sealing rib 22 includes a plurality of first sub-sealing ribs 23. The plurality of first sub-sealing ribs 23 are arranged at intervals along the length direction of the water receiving groove 12. Each first sub-sealing rib 23 extends along the length direction of the water receiving groove 12. A first connecting port 24 is defined between two adjacent first sub-sealing ribs 23. The first connecting port 24 connects the first water receiving area 13 and the second water receiving area 15. By including multiple first sub-sealing ribs 23 in the first sealing rib 22, and by arranging the multiple first sub-sealing ribs 23 at intervals along the length of the water receiving groove 12, a first connecting port 24 can be defined between two adjacent first sub-sealing ribs 23 along the length of the water receiving groove 12. The first connecting port 24 connects the first water receiving area 13 and the second water receiving area 15, so that the water in the first water receiving area 13 can flow from the first connecting port 24 to the second water receiving area 15 under its own gravity. Through the multiple first connecting ports 24 and the drainage groove 17, the water in the first water receiving area 13 can be discharged to the second water receiving area 15 more quickly.

[0074] For example, refer to Figure 7 The length of the first sub-sealing rib 23 is c, and the value of c can be 100mm-200mm. By making the length c of the first sub-sealing rib 23 not less than 100mm, the first sealing rib 22 can play a better sealing role; by making the length c of the first sub-sealing rib 23 not greater than 200mm, the number of first connecting ports 24 can be sufficient, the water in the first water receiving area 13 is closer to the first connecting port 24, and the water in the first water receiving area 13 can flow to the first connecting port 24 more quickly.

[0075] According to some embodiments of the present invention, with reference to Figures 9-12 The first connecting port 24 and the diversion channel 17 are arranged at intervals along the length of the water receiving tank 12. By arranging the first connecting port 24 and the diversion channel 17 at intervals along the length of the water receiving tank 12, water in the first water receiving area 13 can flow to the second water receiving area 15 through the first connecting port 24 and the diversion channel 17 along the length of the water receiving tank 12.

[0076] According to some embodiments of the present invention, with reference to Figure 9The distance between two adjacent first sub-sealing ribs 23 along the length of the water receiving tank 12 is d, and the value of d ranges from 10mm to 15mm. By ensuring that the distance d between two adjacent first sub-sealing ribs 23 along the length of the water receiving tank 12 is not less than 10mm, the opening of the first connecting port 24 can be made large enough to allow water in the first water receiving area 13 to flow to the second water receiving area 15 under its own gravity. By ensuring that the distance d between two adjacent first sub-sealing ribs 23 along the length of the water receiving tank 12 is not greater than 15mm, the sealing effect between the first sealing rib 22 and the heat exchanger components can be improved, ensuring the sealing effect while allowing water in the first water receiving area 13 to be discharged into the second water receiving area 15 through the first connecting port 24.

[0077] According to some embodiments of the present invention, with reference to Figures 9-12 The sealing rib structure 21 also includes a second sealing rib 25, which is located on the side of the first sealing rib 22 away from the second water receiving area 15. The second sealing rib 25 and the first sealing rib 22 are spaced apart along the arrangement direction of the first water receiving area 13 and the second water receiving area 15, and the second sealing rib 25 is arranged along the length direction of the water receiving groove 12. By including the second sealing rib 25 in the sealing rib structure 21, the second sealing rib 25 can prevent water dripping from the heat exchanger assembly 40 into the first water receiving area 13 from splashing outside the first water receiving area 13 and coming into contact with other components, thus avoiding danger. In addition, the second sealing rib 25 is in sealing contact with the heat exchanger assembly 40. The second sealing rib 25 can support the heat exchanger assembly 40 and improve the sealing performance between the heat exchanger assembly 40 and the water receiving tank 12. It can also more effectively prevent unheated airflow from passing between the heat exchanger assembly 40 and the water receiving tank 12. Through the sealing effect of the double sealing ribs in the first sealing rib 22 and the second sealing rib 25, the sealing effect between the heat exchanger assembly 40 and the chassis component 11 can be enhanced.

[0078] According to some embodiments of the present invention, with reference to Figures 5-8 The second sealing rib 25 extends obliquely towards the second water receiving area 15 in a downward direction. By making the second sealing rib 25 extend obliquely towards the second water receiving area 15 in a downward direction, the second sealing rib 25 can more fully separate the first water receiving area 13 from the side of the second sealing rib 25 away from the first water receiving area 13, forming a stepped structure and preventing excessive water in the water receiving tank 12.

[0079] According to some embodiments of the present invention, with reference to Figures 9-12The second sealing rib 25 includes a plurality of second sub-sealing ribs 26, which are arranged at intervals along the length of the water receiving groove 12. Each second sub-sealing rib 26 extends along the length of the water receiving groove 12, and a second connecting port 261 is defined between two adjacent second sub-sealing ribs 26. The second connecting port 261 connects to the areas of the first water receiving area 13 located on both sides of the second sealing rib 25. By arranging multiple second sub-sealing ribs 26 at intervals along the length of the water receiving groove 12, the heat exchanger assembly 40 and the second sealing ribs 25 can both achieve sufficient sealing effect along the length of the water receiving groove 12. By defining a second connecting port 261 between two adjacent second sub-sealing ribs 26, the second connecting port 261 connects the areas of the first water receiving area 13 located on both sides of the second sealing rib 25. While ensuring the sealing effect, water in the area of ​​the first water receiving area 13 located on the side of the second sealing rib 25 away from the second water receiving area 15 can flow into the area of ​​the first water receiving area 13 near the second water receiving area 15 through the second connecting port 261, and then flow into the second water receiving area 15 through the drainage groove 17 and / or the first connecting port 24, thus preventing excessive water overflow from the first water receiving area 13.

[0080] For example, the length of the second sub-sealing rib 26 in the length direction of the water receiving groove 12 is e, and the value of e ranges from 100mm to 200mm.

[0081] According to some embodiments of the present invention, the distance between two adjacent second sub-sealing ribs 26 along the length of the water receiving tank 12 is f, and the value of f ranges from 10mm to 15mm. By ensuring that the distance f between two adjacent second sub-sealing ribs 26 along the length of the water receiving tank 12 is not less than 10mm, the opening of the second connecting port 261 can be made large enough to allow water in the area of ​​the second sealing rib 25 away from the second water receiving area 15 to flow through the second connecting port 261 to the area of ​​the first water receiving area 13 near the second water receiving area 15 under its own gravity. By ensuring that the distance f between two adjacent second sub-sealing ribs 26 along the length of the water receiving tank 12 is not greater than 15mm, the sealing effect between the second sealing rib 25 and the heat exchanger components can be improved.

[0082] For example, the second connecting port 261 and the first connecting port 24 are staggered in the arrangement direction of the first water receiving area 13 and the second water receiving area 15.

[0083] According to some embodiments of the present invention, with reference to Figures 9-12 The drainage boss 27 is connected to the second sealing rib 25. By connecting the drainage boss 27 to the second sealing rib 25, the structural strength of the second sealing rib 25 can be improved, and deformation of the second sealing rib 25 can be avoided; it can also prevent the water in the gap between the drainage boss 27 and the second sealing rib 25 from being difficult to drain.

[0084] According to some embodiments of the present invention, with reference to Figures 5-8 The bottom wall of the first water receiving area 13 is a first bottom wall 14, which extends downward in the direction from the first water receiving area 13 to the second water receiving area 15. By making the bottom wall of the first water receiving area 13 extend downward in the direction from the first water receiving area 13 to the second water receiving area 15, the water in the first water receiving area 13 can flow towards the second water receiving area 15 under its own gravity, making it easier for the water in the first water receiving area 13 to drain and more effectively preventing excessive water overflow from the first water receiving area 13.
