Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a frame for an indoor air conditioner unit and an indoor air conditioner unit. Background Technology

[0002] In wall-mounted air conditioners, components such as the fan and heat exchanger are typically fixed to the frame. When the air conditioner is running, a large amount of condensation inevitably forms on the back of the frame, and this condensation flows down the surface of the frame's back. Currently, to prevent condensation on the back of the frame, a large amount of gaskets needs to be applied, resulting in high production costs.

[0003] The related technology provides an air conditioner indoor unit, in which a heat exchange device for exchanging heat with air flowing through it is provided on the frame. At least one drainage rib is provided on the outer surface of the frame body located behind the heat exchange device. Each drainage rib extends laterally and is directly or indirectly connected to the condensate drainage structure of the frame, so as to guide condensate generated on the outer surface of the frame body to the condensate drainage structure. When condensate is generated on the outer surface of the frame body, the condensate flows along the drainage ribs into the condensate drainage structure, preventing condensate from dripping into the room.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] For recessed air conditioner indoor units, the main frame is usually installed in a nearly horizontal position, and in related technologies, the drainage ribs on the outer surface of the main frame extend laterally. Because the condensate lacks a clear flow direction driven by gravity in a horizontal position, the condensate tends to flow slowly and stagnate locally on the drainage ribs, resulting in low drainage efficiency.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0019] In some embodiments, the height at which the two ends of the first drainage rib protrude from the outer surface of the skeleton body is greater than the height at which the middle part of the first drainage rib protrudes from the outer surface of the skeleton body.

[0020] According to a second aspect of the present invention, an air conditioner indoor unit is provided, including a frame for the air conditioner indoor unit as described in any of the above-disclosed embodiments.

[0045] Combination Figures 1 to 8 As shown, this embodiment of the present disclosure provides a frame 100 for an indoor unit of an air conditioner, including a frame body 10 and a first drainage rib 20. The frame body 10 extends in an arc shape along its own width direction, and the two ends of the frame body 10 along its own width direction are lower than the middle part of the frame body 10. The first drainage rib 20 protrudes from the outer surface of the frame body 10 and extends along the width direction of the frame body 10 to guide the condensate on the outer surface of the frame body 10 to flow along the width direction of the frame body 10 toward the end of the frame body 10.

[0046] The inner side of the frame 100 of the indoor air conditioner is typically used to install components such as the fan and heat exchanger 60. The main body of the frame 10 extends in an arc shape along its width, with both ends lower than the middle, causing the main body of the frame 10 to arch outwards, forming an installation space on the inner side of the frame 10. Components such as the fan and heat exchanger 60 are compactly arranged within the installation space to achieve efficient heat exchange and air circulation functions of the indoor air conditioner.

[0047] The width direction of the main skeleton 10 is as follows Figure 1 As indicated by the middle arrow, the length direction of the main skeleton 10 is as follows: Figure 3 The direction indicated by the middle arrow.

[0048] During the operation of the indoor unit of the air conditioner, the inner side of the frame body 10 comes into contact with the low-temperature heat exchanger 60 and the cold air, resulting in a temperature difference between the inner and outer sides of the frame body 10. This causes condensate to easily condense on the outer surface of the frame body 10. In this embodiment, by providing a first drainage rib 20 extending along the width direction of the frame body 10 on the outer surface of the frame body 10, the condensate can be effectively guided to flow along the width direction of the frame body 10 toward the end of the frame body 10.

[0049] The flow direction of condensate on the outer surface of the main frame 10 is as follows: Figure 3 The direction indicated by the middle arrow.

[0050] This application takes an embedded air conditioner indoor unit as an example. In the installed state, the outer surface of the frame body 10 is nearly horizontal, and the two ends of the frame body 10 along its width direction are located below the middle of the frame body 10. The first drainage rib 20 guides the condensate to flow quickly and orderly to the two ends of the frame body 10, improving the flow speed of the condensate in the horizontal installation state and avoiding local stagnation and random flow of condensate. It can be understood that when the frame 100 is used for a wall-mounted air conditioner indoor unit, the frame body 10 is installed vertically, and the first drainage rib 20 extends along the width direction of the frame body 10, that is, the first drainage rib 20 extends vertically. This can regulate the flow path of the condensate when it flows downward under the action of gravity, avoiding random flow and local stagnation of condensate, and improving the condensate drainage efficiency. Therefore, the frame 100 provided in this embodiment is applicable to both embedded air conditioner indoor units and wall-mounted air conditioner indoor units.

[0051] The frame 100 for an indoor air conditioner provided in this embodiment has a frame body 10 that is an arc-shaped structure with both ends lower than the middle along its width direction. This allows for full utilization of gravity, enabling condensate to flow naturally to both ends of the frame body 10. Simultaneously, a first drainage rib 20 extending along the width direction of the frame body 10 is provided on the outer surface of the frame body 10. This effectively guides the condensate along the drainage rib 20 towards the ends of the frame body 10, further regulating the flow path and preventing condensate from stagnating or flowing randomly on the outer surface of the frame body 10. This improves the efficiency of condensate drainage, allowing it to flow more smoothly and quickly to both ends of the frame body 10. Furthermore, the first drainage rib 20 forms a raised reinforcing structure on the outer surface of the frame body 10, enhancing the overall structural strength of the frame 100 and improving its rigidity and resistance to deformation.

[0052] Optionally, combined Figure 2 As shown, there are multiple first drainage ribs 20, and the multiple first drainage ribs 20 are spaced apart along the length direction of the skeleton body 10.

[0053] Multiple first drainage ribs 20 are spaced apart along the length of the skeleton body 10, dividing the outer surface of the skeleton body 10 into multiple first drainage channels. Each first drainage rib 20 can independently guide condensate to flow to both ends of the skeleton body 10. This increases the drainage path of condensate, making the distribution of condensate on the surface of the skeleton 100 more uniform, thereby avoiding or reducing the accumulation of condensate in local areas and improving the drainage efficiency. At the same time, the spaced first drainage ribs 20 can better adapt to the amount of condensate generated at different locations, and even when the amount of condensate generated is uneven, the condensate can be effectively drained to both ends of the skeleton body 10.

[0054] Optionally, combined Figures 1 to 3 As shown, the length of the first drainage rib 20 is matched with the width of the skeleton body 10.

[0055] This allows the first drainage rib 20 to cover the entire width of the outer surface of the skeleton body 10, improving the drainage effect.

[0056] Optionally, combined Figures 1 to 3 As shown, the frame 100 for the indoor unit of the air conditioner also includes a first frame 30. The first frame 30 is located at the first end of the frame body 10 along its width direction. The first frame 30 extends along the length direction of the frame body 10, and the connection between the first frame 30 and the frame body 10 is bent to form a first drainage groove 31. The first end 21 of the first drainage rib corresponds to the first drainage groove 31.

[0057] The first drainage groove 31, formed by bending between the first frame 30 and the first end of the frame body 10, provides a clear collection and discharge path for condensate flowing towards the first end of the frame body 10. The first end 21 of the first guide rib 20 corresponds to the first drainage groove 31, allowing condensate to be smoothly guided along the first guide rib 20 into the first drainage groove 31 and discharged promptly through the first drainage groove 31. This prevents condensate from dripping into the room when it flows towards the first end of the frame body 10. In addition, the first frame 30 also enhances the structural strength of the frame 100.

[0058] Optionally, combined Figures 1 to 3 As shown, the frame 100 for the indoor unit of the air conditioner also includes a second frame 40. The second frame 40 is located at the second end of the frame body 10 along its width direction. The second frame 40 extends along the length direction of the frame body 10, and the connection between the second frame 40 and the frame body 10 is bent to form a second drainage groove 41. The second end 22 of the first drainage rib corresponds to the second drainage groove 41.

[0059] The second drainage groove 41, formed by bending between the second frame 40 and the second end of the frame body 10, provides a clear collection and discharge path for condensate flowing towards the second end of the frame body 10. The second end 22 of the first guide rib corresponds to the second drainage groove 41, allowing condensate to be smoothly guided along the first guide rib 20 into the second drainage groove 41 and discharged promptly through it. This prevents condensate from dripping into the room when flowing towards the second end of the frame body 10. Furthermore, the second frame 40 also enhances the structural strength of the frame 100.

[0060] A first frame 30 is located at the first end of the frame body 10 along its width direction, and a second frame 40 is located at the second end of the frame body 10 along its width direction. The connection between the first frame 30 and the frame body 10 is bent to form a first drainage groove 31, and the connection between the second frame 40 and the frame body 10 is bent to form a second drainage groove 41. When condensate flows to both ends of the frame body 10 along its width direction, it can flow into the first drainage groove 31 and the second drainage groove 41 respectively, achieving effective collection and discharge of condensate.

[0061] Optionally, combined Figure 2 As shown, the frame 100 for the indoor unit of the air conditioner also includes a plurality of second drainage ribs 32. The plurality of second drainage ribs 32 are disposed on the outer surface of the first frame 30. The plurality of second drainage ribs 32 are spaced apart along the length direction of the frame body 10, and the second drainage ribs 32 extend toward the first drainage groove 31.

[0062] The first frame 30 is connected to the first end of the frame body 10 along its width. During operation of the indoor air conditioning unit, condensation will form on the outer surface of the first frame 30 due to temperature differences. By providing multiple second drainage ribs 32 spaced apart along the length of the frame body 10 on the outer surface of the first frame 30, multiple independent second drainage channels can be formed on the surface of the first frame 30. Thus, when condensation forms on the outer surface of the first frame 30, it can be quickly guided by the second drainage ribs 32 and flow along the extension direction of the second drainage ribs 32 to the first drain trough 31, thereby achieving orderly collection and timely discharge of condensation.

[0063] Optionally, the first frame 30 is the air outlet frame of the indoor unit of the air conditioner.

[0064] Using the air outlet frame of the indoor unit as the first frame 30, on the one hand, it fully utilizes the structural feature of the air outlet frame extending along the length of the frame body 10, forming a stable and continuous connection with the frame body 10, thereby effectively enhancing the overall structural strength and rigidity of the frame 100. On the other hand, the connection between the air outlet frame and the frame body 10 is bent to form a first drainage groove 31, which directly utilizes the existing structure of the air outlet frame, providing a clear collection and drainage path for condensate without adding extra parts. This simplifies the structure of the indoor unit and reduces production costs.

[0065] Optionally, the frame 100 for the indoor unit of the air conditioner also includes a plurality of third drainage ribs 42, which are disposed on the outer surface of the second frame 40. The plurality of third drainage ribs 42 are spaced apart along the length of the frame body 10 and extend toward the second drain groove 41.

[0066] The second frame 40 is connected to the second end of the frame body 10 along its width. During operation of the indoor air conditioning unit, condensation will also form on the outer surface of the second frame 40 due to temperature differences. By providing multiple third drainage ribs 42 spaced apart along the length of the frame body 10 on the outer surface of the second frame 40, multiple independent third drainage channels can be formed on the surface of the second frame 40. Thus, when condensation forms on the outer surface of the second frame 40, it can be quickly guided by the third drainage ribs 42 and flow along the extension direction of the third drainage ribs 42 to the second drain trough 41, thereby achieving orderly collection and timely discharge of condensation.

[0067] Optionally, combined Figure 2 As shown, multiple second drainage ribs 32 and multiple first drainage ribs 20 are arranged alternately.

[0068] The first end 21 of the first drainage rib and the second drainage rib 32 both extend towards the first drainage trough 31. Multiple second drainage ribs 32 and multiple first drainage ribs 20 are staggered, and the projections of the second drainage channels and the first drainage channels in the width direction of the frame body 10 overlap. This effectively disperses the flow direction of condensate, preventing condensate from accumulating in the first drainage trough 31. After condensate is generated on the surfaces of the frame body 10 and the first frame 30, it flows smoothly towards the first drainage trough 31 along the staggered first and second drainage channels, guided by the first drainage ribs 20 and 32. When condensate enters the first drainage trough 31, it flows orderly along multiple staggered drainage paths, avoiding concentrated impact on a certain area, thus reducing water flow congestion and splashing, and effectively improving the condensate drainage efficiency. Simultaneously, the first end 21 of the first drainage rib and one end of the second drainage rib 32 can both be located within the first drainage trough 31. In this case, the staggered arrangement of multiple second drainage ribs 32 and multiple first drainage ribs 20 can effectively increase the gap between the first drainage ribs 20 and the second drainage ribs 32, forming a smoother and more continuous water flow channel inside the first drainage trough 31.

[0069] Optionally, combined Figure 2 and Figure 3 As shown, multiple third drainage ribs 42 correspond one-to-one with multiple first drainage ribs 20, and the corresponding third drainage ribs 42 and first drainage ribs 20 are disconnected at the second drainage channel 41 to form a flow-blocking break 43.

[0070] By setting an anti-stagnant flow break 43 between the first drainage rib 20 and the third drainage rib 42, condensate flows into the second drainage channel 41 and can flow along the second drainage channel 41 between multiple anti-stagnant flow breaks. This can prevent condensate from accumulating or stagnating in the second drainage channel 41, thereby effectively preventing drainage blockage.

[0071] Optionally, the size of the anti-flow-retention break 43 is greater than or equal to 3 mm and less than or equal to 10 mm.

[0072] When the size of the anti-retention break 43 is greater than or equal to 3 mm, condensate can pass smoothly through the anti-retention break 43, avoiding water flow obstruction or blockage due to the size of the anti-retention break 43 being too small, thus maintaining smooth drainage. At the same time, considering that the diameter of water droplets is generally less than 10 mm, when the size of the anti-retention break 43 is less than or equal to 10 mm, it can allow condensate to flow smoothly while maintaining a relatively long length of the third drainage rib 42 and thus the first drainage rib 20, thereby maintaining the structural strength of the frame 100.

[0073] The size of the anti-flow stagnation break 43 can be greater than or equal to 5 mm and less than or equal to 10 mm. Specifically, the size of the anti-flow stagnation break 43 can be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. The size of the anti-flow stagnation break 43 can be any value between 3 mm and 10 mm.

[0074] This embodiment of the invention sets the size of the anti-stagnant flow break 43 to between 3mm and 10mm, which can improve the smoothness of condensate flow and allow the first flow guide 20 and the third flow guide 42 to maintain a relatively long length, thereby effectively enhancing the overall structural strength and stability of the frame 100 and taking into account both drainage efficiency and structural reliability.

[0075] It is understandable that multiple third drainage ribs 42 and multiple first drainage ribs 20 can be staggered; multiple second drainage ribs 32 correspond one-to-one with multiple first drainage ribs 20, and the corresponding second drainage ribs 32 and first drainage ribs 20 are disconnected at the first drainage channel 31 to form an anti-stagnant break 43. This can also prevent condensate from blocking the first drainage channel 31 and the second drainage channel 41.

[0076] Optionally, combined Figure 1 As shown, the skeleton 100 also includes a third frame 80 and a plurality of fourth drainage ribs 82. The third frame 80 is located at the end of the second frame 40 away from the skeleton body 10, and the connection between the third frame 80 and the second frame 40 is bent to form a groove 81. The plurality of fourth drainage ribs 82 are located on the outer surface of the third frame 80. The plurality of fourth drainage ribs 82 are spaced apart along the length direction of the skeleton body 10, and the fourth drainage ribs 82 extend toward the groove 81.

[0077] The third frame 80 is located at the end of the second frame 40 away from the main frame 10. During operation of the indoor air conditioning unit, condensation will form on the outer surface of the third frame 80 due to temperature differences. By providing multiple fourth drainage ribs 82 spaced apart along the length of the main frame 10 on the outer surface of the third frame 80, multiple independent fourth drainage channels can be formed on the surface of the third frame 80. In this way, when condensation forms on the outer surface of the third frame 80, it can be quickly guided by the fourth drainage ribs 82 and flow along the extending direction of the fourth drainage ribs 82 towards the groove 81, preventing disordered flow or stagnation of condensation on the outer surface of the third frame 80.

[0078] Optionally, combined Figure 1 As shown, the third border 80 is higher than the second border 40.

[0079] The third frame 80 is higher than the second frame 40. Under the action of gravity, condensate flows from the third frame 80 along the fourth guide rib 82 into the groove 81, and then continues to flow along the third guide rib 42 into the second drainage groove 41. This creates a continuous and smooth drainage path for the condensate on the outer surface of the third frame 80, preventing condensate from stagnating and accumulating at the third frame 80 or the groove 81, and effectively improving the condensate drainage efficiency.

[0080] Optionally, combined Figure 1 As shown, multiple fourth drainage ribs 82 correspond one-to-one with multiple third drainage ribs 42, and the corresponding fourth drainage ribs 82 and third drainage ribs 42 are disconnected at the groove 81.

[0081] This also allows the corresponding fourth drainage rib 82 and the third drainage rib 42 to form an anti-stagnant break 43, preventing water accumulation in the groove 81.

[0082] Optionally, combined Figures 1 to 3 As shown, a plurality of first drainage ribs 20 are equally spaced along the length of the skeleton body 10. Optionally, a plurality of second drainage ribs 32 are equally spaced along the length of the skeleton body 10. Optionally, a plurality of third drainage ribs 42 are equally spaced along the length of the skeleton body 10. Optionally, a plurality of fourth drainage ribs 82 are equally spaced along the length of the skeleton body 10.

[0083] By arranging the drainage ribs at equal intervals along the length of the main frame 10, condensate can be evenly distributed and orderly guided on the outer surface of the frame 100, preventing excessive local accumulation of condensate that could lead to overflow or dripping. Simultaneously, the equal-interval arrangement improves the symmetry and overall stability of the frame 100 structure, enhancing its strength and rigidity.

[0084] Optionally, combined Figure 1 , Figure 3 andFigure 4 As shown, the first drain trough 31 is provided with a first drain outlet 311, which is adapted to communicate with the water receiving tray 50 of the indoor unit of the air conditioner so that condensate water flows into the water receiving tray 50 through the first drain outlet 311.

[0085] The first drain outlet 311 of the first drain trough 31 is connected to the water receiving tray 50 of the indoor unit of the air conditioner, so that the condensate on the outer surface of the frame body 10 and the first frame 30 can flow smoothly into the drainage system of the indoor unit of the air conditioner.

[0086] Optionally, the first drain outlet 311 is located at the end of the first drain trough 31 along the length of the frame body 10, and the end of the first drain trough 31 along the length of the frame body 10 is lower than its middle part. This allows full use of gravity, enabling condensate to flow naturally to the end and be discharged smoothly.

[0087] Optionally, combined Figure 3 As shown, there are two first drain outlets 311, which are respectively located at both ends of the first drainage channel 31 along the length of the frame body 10. This disperses the flow path of condensate and effectively improves drainage efficiency.

[0088] Optionally, combined Figures 5 to 8 As shown, the second drain trough 41 is provided with a second drain outlet 411, which is adapted to communicate with the water receiving tray 50 of the indoor unit of the air conditioner so that condensate water flows into the water receiving tray 50 through the second drain outlet 411.

[0089] The second drain outlet 411 of the second drain trough 41 is connected to the water receiving tray 50 of the air conditioner indoor unit, so that the condensate on the outer surface of the frame body 10 and the second frame 40 can flow smoothly into the drainage system of the air conditioner indoor unit.

[0090] Optionally, the second drain outlet 411 is located at the end of the second drain trough 41 along the length of the frame body 10, and the end of the second drain trough 41 along the length of the frame body 10 is lower than its middle part. This allows full use of gravity, enabling condensate to flow naturally to the end and be discharged smoothly.

[0091] Optionally, combined Figure 6 As shown, there are two second drain outlets 411, which are respectively located at both ends of the second drainage channel 41 along the length of the main frame 10. By setting two second drain outlets 411, the flow direction of condensate can be dispersed, avoiding local water accumulation in the second drainage channel 41, thereby effectively improving drainage efficiency.

[0092] Optionally, combined Figure 2As shown, the outer surface of the skeleton body 10 is also provided with reinforcing ribs 90, which extend along the length of the skeleton body 10. This can further enhance the overall structural strength and rigidity of the skeleton 100.

[0093] Optionally, combined Figures 1 to 3 As shown, the height of the two ends of the first drainage rib 20 protruding from the outer surface of the skeleton body 10 is greater than the height of the middle part of the first drainage rib 20 protruding from the outer surface of the skeleton body 10.

[0094] The frame body 10 extends in an arc shape along its width, with both ends lower than its middle. The two ends of the first drainage rib 20 refer to the two ends of the first drainage rib 20 along the width direction of the frame body 10. The middle of the first drainage rib 20 refers to the middle of the first drainage rib 20 along the width direction of the frame body 10. The height of the two ends of the first drainage rib 20 protruding from the outer surface of the frame body 10 is greater than the height of the middle part of the first drainage rib 20 protruding from the outer surface of the frame body 10, thus adapting to the arc-shaped structure of the frame body 10. The lower height of the first drainage rib 20 in the middle of the frame body 10 avoids interference with the air conditioner indoor unit casing, while the higher height at both ends ensures that condensate can be smoothly guided to the ends. This allows the first drainage rib 20 to fit the installation space of the frame body 10.

[0095] This disclosure provides an indoor air conditioning unit, including a frame 100 for the indoor air conditioning unit as described in any of the above-disclosed embodiments.

[0096] The air conditioner indoor unit provided in this embodiment includes the frame 100 for the air conditioner indoor unit as described in any of the above-described embodiments, and therefore has all the beneficial effects of the frame 100 for the air conditioner indoor unit as described in any of the above-described embodiments, which will not be repeated here.

[0097] Optionally, combined Figures 3 to 5 As shown, the frame 100 includes a frame body 10, a first frame 30, and a second frame 40. The first end of the frame body 10 along its width direction is connected to the first frame 30 to form a first drainage groove 31. The first drainage groove 31 is provided with a first drainage outlet 311. The second end of the frame body 10 along its width direction is connected to the second frame 40 to form a second drainage groove 41. The second drainage groove 41 is provided with a second drainage outlet 411. The air conditioner indoor unit also includes a water receiving tray 50. The water receiving tray 50 is located below the frame 100. The water receiving tray 50 corresponds to the first drainage outlet 311. The side wall of the first drainage outlet 311 extends toward the water receiving tray 50 so that condensate flows into the water receiving tray 50 through the first drainage outlet 311.

[0098] By extending the sidewall of the first drain outlet 311 toward the water receiving tray 50, the condensate in the first drain trough 31 can be effectively guided directly into the water receiving tray 50, avoiding splashing or dripping of the condensate during the drainage process and improving the stability of the drainage process.

[0099] Optionally, combined Figure 5 As shown, the indoor unit of the air conditioner also includes a heat exchanger 60, which is located between the frame 100 and the water collection tray 50. The heat exchanger 60 has an end plate 70 at its end along the length of the frame body 10, and the end plate 70 corresponds to the water collection tray 50. The side wall of the second drain port 411 abuts against the outer surface of the end plate 70 so that condensate flows into the water collection tray 50 along the end plate 70 after passing through the second drain port 411.

[0100] By abutting the sidewall of the second drain outlet 411 against the outer surface of the end plate 70, the existing structure of the end plate 70 of the indoor air conditioning unit is fully utilized, allowing the end plate 70 to serve both a structural support function and as a condensate drain plate. The end plate 70 can be located above the drip tray. Condensate can flow smoothly along the outer surface of the end plate 70 into the drip tray 50, preventing dripping or splashing at the second drain outlet 411. This simplifies the drainage structure and reduces manufacturing costs.

[0101] Optionally, the indoor unit of the air conditioner also includes a fan, which is located inside the frame 100 and between the frame 100 and the heat exchanger 60.

[0102] Placing the fan inside the frame 100, between the frame 100 and the heat exchanger 60, optimizes the internal spatial layout of the indoor unit, allowing the fan to drive airflow more effectively and improving heat exchange efficiency. Simultaneously, this arrangement makes the airflow path between the fan and the heat exchanger 60 more compact, reducing airflow losses and improving the overall energy efficiency of the air conditioning system. The fan can be a cross-flow fan, with its axis aligned with the length of the frame 100, further enhancing air delivery.
