[0028] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. The invention is now further described in conjunction with the accompanying drawings and embodiments:

[0029] Please see Figure 1-5 An optimized structure for an air conditioner injection-molded housing based on anti-condensation includes an air conditioner injection-molded housing, wherein the air conditioner injection-molded housing includes an upper air outlet plate 1 and a lower air outlet plate 2, an air outlet 3 is formed between the upper air outlet plate and the lower air outlet plate, the end of the lower air outlet plate is a planar structure with a groove, and the end of the upper air outlet plate is a trapezoidal boss structure.

[0030] The upper air outlet plate has an upper anti-condensation part 5 at its end. The upper anti-condensation part consists of a protrusion 51 and a connecting part 52. The protrusion is connected to the connecting part, and the connecting part is connected to the upper air outlet plate.

[0031] The protrusion is arranged parallel to the upper air outlet plate, and the angle between the upper air outlet plate and the connecting part is greater than 90°.

[0032] The angle between the upper air outlet plate and the connecting part is 120°-150°.

[0033] Preferably, the angle between the upper air outlet plate and the connecting part is 120°.

[0034] Preferably, the angle between the upper air outlet plate and the connecting part is 145°.

[0035] The lower air outlet plate 2 is provided with a lower anti-condensation part 6 at its end. The lower anti-condensation part includes a first end 61, a second end 62 and a groove 63. The first end is connected to the lower air outlet plate, the second end is connected to the first end, and the groove is located between the first end and the second end.

[0036] The angle between the first end and the lower air outlet plate is 140°-150°.

[0037] Preferably, the angle between the first end and the lower air outlet plate is 145°.

[0038] The existing lower air outlet panel has a pointed end structure. The low-temperature gas blown out by the indoor unit of the air conditioner directly meets the hot air, causing a rapid cooling effect. When the temperature of the hot air drops below the dew point, condensation forms at the lower air outlet panel, potentially leading to leaks. This invention optimizes the structure of the lower air outlet panel by changing the pointed end to a flat structure. This increases the distance between the end and bottom of the lower air outlet panel, effectively creating a buffer zone. External humid air is not subjected to rapid cooling, preventing condensation and improving leaks caused by condensation. Furthermore, the flat structure of the lower air outlet panel has grooves. These grooves increase the surface area for condensation adhesion, and the increased airflow at this location accelerates condensation evaporation, directly reducing the risk of condensation.

[0039] Existing air vent panels have a planar structure, where the low-temperature gas blown out by the indoor unit of the air conditioner directly meets the hot air, causing a rapid cooling effect. When the temperature of the hot air drops below the dew point, condensation can form at the air vent panel, potentially leading to leaks. This invention optimizes the structure of the air vent panel by transforming the end plane into a trapezoidal protrusion. This trapezoidal protrusion increases the distance between the low-temperature gas blown out by the indoor unit and the end of the air vent panel, effectively creating a cold / hot buffer zone. This buffer zone helps reduce the amount of cold air emitted from the indoor unit, while the trapezoidal protrusion increases the airflow velocity at this point, facilitating condensation evaporation and preventing condensation at the air vent panel.

[0040] The height of the lower anti-condensation section is 6-8mm.

[0041] Preferably, the height of the lower anti-condensation section is 7mm.

[0042] The depth of the groove is 1.5-3mm.

[0043] Preferably, the depth of the groove is 2 mm.

[0044] Preferably, it also includes a drainage section 4, which is disposed inside the air outlet, and the junction of the drainage section and the air outlet is an arc-shaped transition structure 41.

[0045] In existing air conditioners, the junction between the air intake section and the air outlet of the injection-molded casing is a 90° right-angle transition structure. Due to the significant difference in airflow between the air intake section and the air outlet, a convergence zone of hot and cold air is easily formed, creating a potential condensation problem. This invention optimizes the junction between the air intake section and the air outlet from a 90° right-angle transition structure to a rounded transition structure, increasing the airflow at the air intake section and reducing the risk of condensation.

[0046] This invention addresses the potential quality issues of condensation and dripping water near the air outlet of the indoor unit of an air conditioner by optimizing the upper air outlet plate, lower air outlet plate, and air diversion part of the air conditioner's injection-molded housing.

[0047] Working principle of the invention:

[0048] The tip structure at the end of the lower air outlet was changed to a flat structure with grooves. The distance between the end of the lower air outlet and the bottom was increased to form a buffer zone for hot and cold air. At the same time, due to the effect of the groove structure, the movement of condensed water vapor was accelerated, avoiding the accumulation of water droplets and solving the problem of condensation and water leakage at the lower panel.

[0049] The end plane of the upper air outlet is optimized into a trapezoidal protrusion structure. This trapezoidal protrusion structure changes the direction of the low-temperature gas, increasing the distance between the cold air and the panel to form a buffer zone, which helps to solve the problems of condensation and dripping water on the upper air outlet.

[0050] The junction between the air intake and the air outlet has been optimized from a 90° right-angle transition structure to a rounded transition structure, increasing the airflow at the air intake location and reducing the risk of condensation at the air intake location.

[0051] Implementation Case 1:

[0052] An optimized structure for an air conditioner injection-molded housing based on anti-condensation includes an air conditioner injection-molded housing. The housing comprises an upper air outlet plate and a lower air outlet plate, with an air outlet formed between them. The lower air outlet plate has a planar structure with a groove at its end, while the upper air outlet plate has a trapezoidal boss structure at its end. The upper air outlet plate has an upper anti-condensation portion at its end, consisting of a protrusion and a connecting portion. The protrusion is connected to the connecting portion, which in turn is connected to the upper air outlet plate. The protrusion is parallel to the upper air outlet plate, and the angle between the upper air outlet plate and the connecting portion is 120°. The lower air outlet plate has a lower anti-condensation portion at its end, comprising a first end, a second end, and a groove. The first end is connected to the lower air outlet plate, and the second end is connected to the first end. The groove is located between the first end and the second end. The angle between the first end and the lower air outlet plate is 140°. The height of the lower anti-condensation portion is 6 mm. The depth of the groove is 2.5 mm.

[0053] After optimizing the structure of the lower air outlet panel, the pointed end of the panel is transformed into a flat structure. This increases the distance between the end and the bottom of the panel, effectively creating a thermal buffer zone. External humid air is prevented from being blasted into cold air, thus preventing condensation and mitigating leakage caused by condensation. Furthermore, the flat structure of the lower air outlet panel has grooves, which increase the surface area for condensate adhesion and increase airflow velocity, accelerating condensate evaporation and directly reducing the risk of condensation. Similarly, after optimizing the structure of the upper air outlet panel, the end plane is transformed into a trapezoidal protrusion. This trapezoidal protrusion increases the distance between the low-temperature air blown from the indoor unit and the end of the upper air outlet panel, creating a thermal buffer zone. This buffer zone helps reduce the amount of cold air emitted from the indoor unit, while the trapezoidal protrusion increases airflow velocity, promoting condensate evaporation and preventing condensation on the upper air outlet panel.

[0054] Implementation Case 2:

[0055] An optimized structure for an air conditioner injection-molded housing based on anti-condensation includes an air conditioner injection-molded housing comprising an upper air outlet plate and a lower air outlet plate, with an air outlet formed between the upper and lower air outlet plates. The lower air outlet plate has a planar structure with a groove at its end, and the upper air outlet plate has a trapezoidal boss structure at its end. The upper air outlet plate has an upper anti-condensation part at its end, which consists of a protrusion and a connecting part. The protrusion is connected to the connecting part, and the connecting part is connected to the upper air outlet plate.

[0056] The protrusion is parallel to the upper air outlet plate, and the angle between the upper air outlet plate and the connecting part is 145°. The lower air outlet plate has a lower anti-condensation part at its end, comprising a first end, a second end, and a groove. The first end is connected to the lower air outlet plate, the second end is connected to the first end, and the groove is located between the first and second ends. The angle between the first end and the lower air outlet plate is 145°. The height of the lower anti-condensation part is 7mm. The depth of the groove is 2mm. Optimizing the structure of the lower air outlet plate by transforming the pointed end into a planar structure increases the distance between the end and bottom of the lower air outlet plate, effectively creating a hot-cold buffer zone. External humid air will not experience a sudden cooling effect, preventing condensation and improving leakage problems caused by condensation. Furthermore, the planar structure of the lower air outlet plate has a groove, which increases the adhesion area of ​​condensate and increases the airflow velocity at that location, accelerating condensate evaporation and directly reducing the risk of condensation. After optimizing the structure of the upper air outlet panel, the end plane of the upper air outlet panel is optimized into a trapezoidal boss structure. This trapezoidal boss structure increases the distance between the low-temperature gas blown out by the indoor unit of the air conditioner and the end of the upper air outlet panel, that is, a cold and hot buffer zone is added at the end of the upper air outlet panel. This cold and hot buffer zone helps to reduce the amount of cold air blown out by the indoor unit. At the same time, the trapezoidal boss structure increases the airflow velocity at this point, which helps the evaporation of condensate and prevents condensation problems from occurring on the upper air outlet panel.

[0057] The air conditioner's injection-molded housing includes an air intake section located within the air outlet. The junction between the air intake section and the air outlet is a rounded transition structure. Optimizing the junction between the air intake section and the air outlet from a 90° right-angle transition structure to a rounded transition structure increases the airflow at the air intake section location and reduces the risk of condensation at that location.

[0058] Implementation Case 3:

[0059] An optimized structure for an air conditioner injection-molded housing based on anti-condensation includes an air conditioner injection-molded housing comprising an upper air outlet plate and a lower air outlet plate, with an air outlet formed between the upper and lower air outlet plates. The lower air outlet plate has a planar structure with a groove at its end, and the upper air outlet plate has a trapezoidal boss structure at its end. The upper air outlet plate has an upper anti-condensation part at its end, which consists of a protrusion and a connecting part. The protrusion is connected to the connecting part, and the connecting part is connected to the upper air outlet plate.

[0060] The protrusion is parallel to the upper air outlet plate, and the angle between the upper air outlet plate and the connecting part is 150°. The lower air outlet plate has a lower anti-condensation part at its end, comprising a first end, a second end, and a groove. The first end is connected to the lower air outlet plate, the second end is connected to the first end, and the groove is located between the first and second ends. The angle between the first end and the lower air outlet plate is 150°. The height of the lower anti-condensation part is 8mm. The depth of the groove is 3mm. Optimizing the structure of the lower air outlet plate by transforming its tip into a planar structure increases the distance between the end and bottom of the lower air outlet plate, effectively creating a hot and cold buffer zone. External humid and hot air will not experience a sudden cooling effect, preventing condensation and improving leakage problems caused by condensation. Furthermore, the planar structure of the lower air outlet plate has a groove, which increases the adhesion area of ​​condensate and increases the airflow velocity at that location, accelerating condensate evaporation and directly reducing the risk of condensation. After optimizing the structure of the upper air outlet panel, the end plane of the upper air outlet panel is optimized into a trapezoidal protrusion structure. This trapezoidal protrusion structure increases the distance between the low-temperature gas blown out by the indoor unit of the air conditioner and the end of the upper air outlet panel, thus adding a cold and hot buffer zone at the end of the upper air outlet panel. This cold and hot buffer zone helps reduce the amount of cold air discharged from the indoor unit. At the same time, the trapezoidal protrusion structure increases the airflow velocity at this point, which helps the evaporation of condensate and prevents condensation problems on the upper air outlet panel. The air conditioner injection-molded housing includes a guide section, which is located inside the air outlet. The junction between the guide section and the air outlet is a rounded transition structure. Optimizing the junction between the guide section and the air outlet from a 90° right-angle transition structure to a rounded transition structure increases the airflow at the guide section location and reduces the risk of condensation at the guide section location.
