Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning outlet technology, specifically to an air conditioning outlet structure for high temperature and high humidity areas. Background Technology
[0002] Air conditioning vents are the terminal devices in an air conditioning system that deliver cool air into the room. They are usually made of metal or wood. Their core function is to evenly distribute cooled and dehumidified air into the indoor environment. In areas with high temperature and humidity, the temperature of the air supplied is much lower than the dew point temperature of the indoor air, which is also hot and humid. Water droplets easily condense and drip at the vents, leading to mold on the walls and damage to decorations. Traditional aluminum alloy vents have high thermal conductivity, which exacerbates condensation. While wooden vents can alleviate the problem, they have drawbacks such as high cost, easy deformation, or flammability. Furthermore, the water that accumulates during condensation can easily breed bacteria and other microorganisms, which is not conducive to clean indoor air and may exacerbate air pollution.
[0003] Therefore, in order to address the above problems, a new air supply outlet structure for air conditioning in high-temperature and high-humidity areas is proposed. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by developing an air conditioning outlet structure for high-temperature and high-humidity areas. This invention can reduce condensation at the air conditioning outlet in high-temperature and high-humidity areas, and also reduce the long-term adhesion of condensation to the walls at the outlet, thus preventing the growth of bacteria and other microorganisms and improving its practicality.
[0005] To achieve the above objectives, this utility model employs the following technical solution:
[0006] An air supply outlet structure for air conditioning in high-temperature and high-humidity areas includes an air supply duct. The air supply duct is configured with a multi-layer structure. Several guide grooves are provided on the inner side wall of the air supply duct. The guide grooves are inclined and their bottom ends are close to the outlet end of the air supply duct. The cross-section of the top of the inner side of the air supply duct is herringbone-shaped, and the cross-section of the bottom of the inner side of the air supply duct is arc-shaped. A guide groove is opened at the bottom of the arc along the length of the air supply duct. The height of the bottom of the guide groove gradually decreases from the rear end of the air supply duct to the outlet end. Several transverse guide vanes are rotatably arranged on the inner side wall of the air supply duct near the outlet end. An air outlet frame is connected to the outer side of the outlet end of the air supply duct. Several vertical guide vanes are rotatably arranged on the air outlet frame, and a waterproof layer is provided on the outer surface of the air outlet frame.
[0007] As a preferred embodiment, the multi-layer structure of the air supply duct consists of an inner layer, an insulation layer, an outer layer, and a waterproof layer from the inside out. Both the inner and outer layers are made of plastic. The gap between the inner and outer layers is the insulation layer, which is filled with polyurethane foam. The waterproof layer is located on the outside of the outer layer and is made of foam insulation board, which is tightly attached to the outside of the outer layer.
[0008] Preferably, a rectifier plate is installed inside the air supply duct, which covers the cross-section of the air supply duct and has several ventilation holes evenly distributed on it.
[0009] Preferably, a drainage groove is provided at the bottom of the inner side of the air vent frame, the height of the bottom of the drainage groove gradually increases from the middle to both ends, a drainage hole is opened through the bottom of the drainage groove, and a drainage nozzle is provided on the outside of the drainage hole.
[0010] Preferably, an inclined surface is provided on the inner side of the air vent frame at the bottom of the vertical guide vane, the inclined surface is inclined towards the drainage trough, the vertical guide vane is located on the inclined surface, and the orthographic projection of the rotation range of the vertical guide vane is located on the inclined surface, so that the water droplets falling up and down the vertical guide vane can fall on the inclined surface and be guided to the drainage trough by the inclined surface.
[0011] Preferably, a circumferential baffle groove is provided on the inner wall of the side of the transverse guide vane near the outlet end of the air supply duct. The baffle groove is located on the outermost side of the inner wall of the air supply duct. The baffle groove connects the guide groove and the diversion groove. A guide plate is provided directly below the position where the baffle groove and the diversion groove connect. The end of the guide plate away from the baffle groove is located directly above the drain hole.
[0012] Preferably, a base plate is provided on the outer side of the outlet end of the air supply duct, and a circumferential slot is opened on the base plate. A circumferential insert plate is provided on the side of the air outlet frame close to the base plate corresponding to the slot. The insert plate can be inserted into the slot, and a rubber waterproof strip is provided between the slot and the insert plate to prevent leakage. Corresponding connecting plates are provided on the outer side of the base plate and the air outlet frame, and the connecting plates are connected by bolts and nuts.
[0013] Preferably, a hydrophilic coating is provided on the surface of the inner wall of the air supply duct, the inner wall of the guide groove, the inner wall of the drainage groove, the inner wall of the baffle groove, the surface of the horizontal guide blade, the surface of the vertical guide blade, and the inner side of the air outlet frame.
[0014] Preferably, the waterproof layer on the outer surface of the air vent frame is a hydrophobic coating.
[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages:
[0016] 1. This utility model sets up a multi-layered air supply duct to separate the temperature of the inner and outer sides of the air supply duct, so as to avoid excessive temperature difference between the outer and inner sides of the air supply duct and thus prevent condensation from occurring on the outer wall of the air supply duct. In addition, the water-proof layer on the outer side of the air supply duct is made of foam board, which can further prevent condensation from occurring.
[0017] 2. This utility model, by setting a rectifier plate and opening several ventilation holes on the rectifier plate, makes the airflow more uniform, reduces eddies, and avoids local high-speed low-temperature airflow directly impacting a certain point of the air outlet, resulting in excessive cooling and condensation.
[0018] 3. This utility model provides a way to guide the condensation that may form on the inner wall of the air supply duct by opening inclined guide grooves, diversion grooves and baffle grooves on the inner wall of the air supply duct. This prevents the condensation from forming on the inner wall of the air supply duct from sticking on the wall and causing bacteria to grow over a long period of time. In particular, condensation is likely to occur during the period after the air conditioner is turned on and off due to the change in surface temperature of the inner wall of the air supply duct.
[0019] 4. This utility model sets up an air vent frame and a drainage groove inside the air vent frame to collect the condensed dew and draw the dew out, thus avoiding the accumulation of dew and the easy growth of bacteria.
[0020] 5. By setting horizontal guide vanes and vertical guide vanes, with the horizontal guide vanes located on the inner side and the vertical guide vanes located on the outer side, the vertical guide vanes have more contact with the external high temperature and high humidity air, making condensation more likely. The condensation can flow down the vertical guide vanes to the inclined surface under the action of gravity, and finally flow into the drainage trough, making it more practical.
[0021] 6. By setting a hydrophilic coating, this utility model enables small water droplets to spread quickly and form a water film, which is easily guided away and reduces the possibility of large water droplets forming. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figures 1-4 As shown, this utility model provides a technical solution:
[0030] An air supply outlet structure for air conditioning in high-temperature and high-humidity areas includes an air supply duct 1. The air supply duct 1 is configured with a multi-layer structure to isolate the air inside and outside the air supply duct 1. Several parallel guide grooves 2 are provided on the inner side wall of the air supply duct 1 near the air outlet end. The guide grooves 2 are inclined and their bottom ends are close to the outlet end of the air supply duct 1. The cross-section of the top of the inner side of the air supply duct 1 is shaped like a herringbone, and the cross-section of the bottom of the inner side of the air supply duct 1 is arc-shaped. At the bottom of the arc shape, a diversion groove 3 is opened along the length of the air supply duct 1. The height of the bottom of the diversion groove 3 gradually decreases from the rear end of the air supply duct 1 to the outlet end to draw water out of the air supply duct 1. Several horizontal guide vanes 4 are rotatably arranged on the inner side wall of the air supply duct 1 near the outlet end to adjust the up and down airflow direction. An air outlet frame 5 is connected to the outer side of the outlet end of the air supply duct 1. Several vertical guide vanes 6 are rotatably arranged on the air outlet frame 5 to adjust the left and right airflow direction. A waterproof layer is provided on the outer surface of the air outlet frame 5.
[0031] In an optional embodiment, the multi-layer structure of the air supply duct 1 consists of an inner layer 101, a thermal insulation layer 102, an outer layer 103, and a waterproof layer 104 from the inside out. The inner layer 101 and the outer layer 103 are both made of plastic, which is economical, lightweight, and not prone to condensation. The gap between the inner layer 101 and the outer layer 103 is the thermal insulation layer 102, which is filled with polyurethane foam. The waterproof layer 104 is located on the outside of the outer layer 103 and is made of foam insulation board, which is tightly attached to the outside of the outer layer 103.
[0032] In an optional embodiment, a rectifier plate 7 is detachably installed inside the air supply duct 1. The rectifier plate 7 covers the cross-section of the ventilation channel inside the air supply duct 1. Several ventilation holes 8 are evenly opened on the rectifier plate 7, which can make the cold air inside the air supply duct 1 more evenly distributed and avoid excessively low local temperature causing condensation.
[0033] In an optional embodiment, a drainage groove 9 is provided at the bottom of the inner side of the air vent frame 5. The height of the bottom of the drainage groove 9 gradually increases from the middle to both ends. A drainage hole 10 is opened through the bottom of the drainage groove 9. A drainage nozzle 11 is provided on the outside of the drainage hole 10. The drainage nozzle 11 can be connected to the drainage riser through a flexible hose. The drainage riser merges with the drainage pipe of the indoor unit of the air conditioner to drain the water at the air outlet and prevent water from accumulating and breeding bacteria and mold, which would affect air quality.
[0034] In an optional embodiment, an inclined surface 12 is provided on the inner side of the air vent frame 5 at the bottom of the vertical guide vane 6. The inclined surface 12 is inclined towards the drainage groove 9. The vertical guide vanes 6 are all located on the inclined surface 12, and the orthographic projection of the rotation range of the vertical guide vanes 6 is all located on the inclined surface 12. This ensures that the water droplets falling from the vertical guide vanes 6 can fall on the inclined surface 12 and be guided into the drainage groove 9 by the inclined surface 12, so as to avoid the water droplets dripping.
[0035] In an optional embodiment, a circumferential baffle groove 13 is provided on the inner wall of the transverse guide vane 4 near the outlet end of the air supply duct 1. The baffle groove 13 is located on the outermost side of the inner wall of the air supply duct 1. The baffle groove 13 connects the guide groove 2 and the diversion groove 3. A guide plate 14 is provided directly below the position where the baffle groove 13 connects with the diversion groove 3. The end of the guide plate 14 away from the baffle groove 13 is located directly above the drain hole 10 to prevent condensed water droplets from being blown out of the air supply outlet, as splashing water droplets is difficult to clean.
[0036] In an optional embodiment, the transverse guide vanes 4 rotate simultaneously with each other and the vertical guide vanes 6 rotate simultaneously with each other. Their connection structure can adopt the existing air conditioning blade connection structure, which is more economical and does not affect the effect of this application.
[0037] In an optional embodiment, a base plate 15 is provided on the outer side of the outlet end of the air supply duct 1. A circumferential slot 16 is formed on the base plate 15. A circumferential insert plate 17 is provided on the side of the air outlet frame 5 near the base plate 15 corresponding to the slot 16. The insert plate 17 can be inserted into the slot 16, and a rubber waterproof strip is provided between the slot 16 and the insert plate 17 to prevent water leakage. Corresponding connecting plates 18 are provided on the outer side of the base plate 15 and the air outlet frame 5. The connecting plates 18 are connected by bolts and nuts to make the connection between the air outlet frame 5 and the air supply duct 1 tighter and improve the performance.
[0038] In an optional embodiment, a hydrophilic coating is provided on the inner wall of the air supply duct 1, the inner wall of the guide groove 2, the inner wall of the diversion groove 3, the inner wall of the drainage groove 9, the inner wall of the baffle groove 13, the surface of the horizontal guide vane 4, the surface of the vertical guide vane 6, and the inner side of the air outlet frame 5. The hydrophilic coating is a polyacrylic coating or a siloxane coating, which allows the condensed small water droplets to spread quickly to form a water film, which is easily guided away, reducing the possibility of large water droplets forming.
[0039] In an optional embodiment, the waterproof layer on the outer surface of the air vent frame 5 is configured as a hydrophobic coating to prevent liquid contamination of the surface of the air vent frame 5.
[0040] Working principle: When the air conditioner is turned on or off, condensation is likely to occur on the inside of the air supply duct 1 due to temperature changes. The condensation on the inner wall is guided to the outside of the air supply duct 1 by the flow guide trough 2, the flow diversion trough 3, and the flow baffle trough 13 to prevent the condensation from accumulating inside. The water discharged to the outside of the air supply duct 1 is then discharged to the outside through the drain trough 9 and the hose. A detachable rectifier plate 7 is installed on the inside of the air supply duct 1 to evenly discharge the cold air and prevent the temperature from being too low, which would easily cause condensation. The hydrophilic coating allows the condensed water droplets to spread quickly and form a water film, which is easily guided away, preventing the growth of bacteria and microorganisms and improving practicality.
