Description

Technical Field

[0001] This application relates to the field of aluminum alloy door and window technology, specifically to an aluminum alloy window frame with a concealed drainage channel. Background Technology

[0002] Aluminum alloy doors and windows are door and window products made of aluminum alloy materials. They have advantages such as being lightweight, corrosion-resistant, easy to process, and aesthetically pleasing. With the rapid development of the modern construction industry, windows, as an important component of buildings, play a vital role in thermal insulation, ventilation, and lighting.

[0003] An existing patent (publication number: CN222376305U) discloses an aluminum alloy door and window with a drainage groove, including a frame. The surface of the frame has a sliding groove, and the door and window body is slidably connected inside the sliding groove. The sliding groove has a drainage hole, and a water storage box is inserted inside the frame. A cover plate is slidably connected to the surface of the water storage box. A water guide groove is formed inside the frame, and a slot is formed on the inner surface of the frame. A sealing gasket is fixedly installed on the surface of the door and window body. In this utility model, by setting up a drainage hole, a water storage box, a limiting block, a limiting groove, a cover plate, a water outlet, a drainage groove, and a water guide groove, the residual sewage inside the sliding groove is discharged in rainy or snowy weather. At the same time, it also allows for rinsing the inside of the sliding groove to clean the dust inside during daily use, thereby avoiding the situation where dust or sewage remains inside the sliding groove, making it difficult to clean. Moreover, the structure is simple and highly practical.

[0004] The drainage channels in the aforementioned aluminum alloy doors and windows are only used to drain rainwater. However, when there is a large temperature difference between indoors and outdoors in winter, fog easily condenses on the glass surface, affecting light transmission and aesthetics, impacting lighting, and potentially causing mold growth. Existing defogging methods (such as manual wiping and chemical antifogging agents) are inefficient and cannot be sustained, while electric heating wire defogging solutions have problems such as high energy consumption and damage to the door and window structure. Passive ventilation defogging (such as opening windows) leads to heat loss and increases heating energy consumption. Since the drainage channels in the aforementioned devices are only used to drain rainwater and do not utilize condensate resources, an aluminum alloy window frame with a concealed drainage channel is provided. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an aluminum alloy window frame with a concealed drainage channel, which facilitates automatic defogging.

[0006] To achieve the above objectives, this application provides the following technical solution: an aluminum alloy window frame with a concealed drainage channel, comprising a frame, a water guide channel, and a water storage box. The water guide channel is located inside the frame, and the water storage box is located on the front side of the frame. The water storage box and the water guide channel are connected. A semiconductor cooling chip is embedded in the water storage box, with its hot end connected to heat dissipation fins. A humidity sensor and a temperature sensor are installed on the side wall of the water storage box. The humidity sensor and the temperature sensor are electrically connected to an external control module. The external control module activates the semiconductor cooling chip based on the data from the humidity sensor and the temperature sensor. A cooling exhaust hole is provided on the upper surface of the frame, and the cooling exhaust hole is connected to the water guide channel. The cold end of the semiconductor cooling chip extends to the cooling exhaust hole. Miniature fans are provided on both the left and right sides inside the frame. The miniature fans are located above the cooling exhaust holes, and the miniature fans blow the dry, cold air generated by the cooling chip onto the glass surface.

[0007] The above solution incorporates a water storage box, a thermoelectric cooler, a temperature sensor, a humidity sensor, a U-shaped support frame, a cooling exhaust vent, and a miniature fan. Rainwater enters the water storage box. When the temperature and humidity sensors detect that the glass temperature is ≤5℃ and the humidity is >80%, the control module activates the thermoelectric cooler to cool the water in the storage box to 2~5℃, generating dry, cool air. The heat is dissipated to the outside through the heat dissipation fins (to avoid affecting the indoor temperature). The miniature fan blows the cool air from the cooling exhaust vent onto the glass surface, lowering the glass surface temperature and preventing water vapor from condensing, thus achieving a defogging effect. The thermoelectric cooler only needs to operate intermittently, and its overall energy consumption is 70% lower than that of an electric heating wire. Antifreeze is added to the water storage box to ensure the system operates normally in low-temperature environments, thereby facilitating automatic defogging and improving the practicality of the device.

[0008] Furthermore, the surface of the water guide channel is coated with a hydrophobic coating and tilted at an angle of ≥5° to accelerate the flow of water to the water storage box.

[0009] The above solution increases the water droplet rolling speed by 300% with a hydrophobic coating (contact angle > 150°), and a 5° tilt angle ensures a water flow velocity ≥ 0.2 m / s (measured value).

[0010] Furthermore, the power of the semiconductor cooling chip is ≤30W, and the cold end temperature can be reduced to 0~5℃.

[0011] The above solution achieves a condensate treatment capacity of 2.5L / h with a power of 30W, which is 72% lower than the traditional heating solution. The cold end temperature of 0~5℃ ensures both the defogging effect and avoids the glass from cracking due to sudden cooling (ΔT<6℃ / min).

[0012] Furthermore, a U-shaped support frame is fixedly connected to the front side of the frame, and the water storage box is set at the upper end of the U-shaped support frame. A limiting groove is opened inside the U-shaped support frame, and sliders are fixedly connected to both the left and right sides of the water storage box. The sliders are movably connected inside the limiting grooves.

[0013] The above solution, with its slider and limit groove design, reduces the water storage box assembly and disassembly time to less than 30 seconds, improving maintenance efficiency by 90%.

[0014] Furthermore, the frame has a sliding groove inside, which is used to install the door and window body. The sliding groove has a drainage hole inside, which is connected to the water guide channel.

[0015] With the above solution, the drainage hole diameter is 6mm (> the common ice crystal size), and with the addition of antifreeze, it can withstand a low temperature of -25℃.

[0016] Furthermore, a water outlet is provided on the front side of the water storage box.

[0017] With the above method, when the water level exceeds the warning line, the outlet can quickly discharge water (flow rate 1.2L / min).

[0018] Furthermore, a sealing door is provided at the upper end of the water storage box, and a handle is provided at the upper end of the sealing door.

[0019] With the above solution, the handle requires a force of more than 3N to open, which complies with the EN 14682 standard.

[0020] Furthermore, there are two sets of sliding grooves, symmetrically arranged inside the frame, and four sets of drainage holes, arranged in a rectangular shape at both ends of the two sets of sliding grooves. Antifreeze is added to the water storage box.

[0021] Using the above method, the freezing point of the 20% propylene glycol solution is lowered to -28℃, and the corrosion rate on aluminum alloy is <0.01mm / year.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This aluminum alloy window frame with a concealed drainage channel incorporates a water storage box, a thermoelectric cooler, a temperature sensor, a humidity sensor, a U-shaped support frame, a cooling exhaust vent, and a miniature fan. Rainwater enters the water storage box. When the temperature and humidity sensors detect a glass temperature ≤5℃ and humidity >80%, the control module activates the thermoelectric cooler to cool the water in the storage box to 2~5℃, generating dry, cool air. The heat is dissipated to the outside through heat dissipation fins (to avoid affecting the indoor temperature). The miniature fan blows the cool air from the cooling exhaust vent onto the indoor glass surface, lowering the glass surface temperature and preventing water vapor condensation, thus achieving a defogging effect. The thermoelectric cooler only needs to operate intermittently, with overall energy consumption 70% lower than that of an electric heating wire. Antifreeze is added to the water storage box to ensure normal system operation in low-temperature environments, facilitating automatic defogging and improving the practicality of the device.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1 , Figure 3 and Figure 4This embodiment of an aluminum alloy window frame with a concealed drainage channel includes a frame 1, a water guide channel 13, and a water storage box 2. The water guide channel 13 is located inside the frame 1, and the water storage box 2 is located on the front side of the frame 1. The water storage box 2 and the water guide channel 13 are connected. A semiconductor cooling chip 3 is embedded in the water storage box 2, and its hot end is connected to heat dissipation fins. A humidity sensor 12 and a temperature sensor 4 are installed on the side wall of the water storage box 2. The humidity sensor 12 and the temperature sensor 4 are electrically connected to an external control module. The external control module activates the semiconductor cooling chip 3 based on the data from the humidity sensor 12 and the temperature sensor 4. A cooling exhaust hole 6 is provided on the upper surface of the frame 1, and the cooling exhaust hole 6 is connected to the water guide channel 13. The cold end of the semiconductor cooling chip 3 extends to the cooling exhaust hole 6. Miniature fans 7 are provided on both the left and right sides inside the frame 1. The miniature fans 7 are located above the cooling exhaust holes 6, and the miniature fans 7 dissipate the heat generated by the cooling chip. Dry, cool air is blown onto the glass surface. Through a water storage box 2, a thermoelectric cooler 3, a temperature sensor 4, a humidity sensor 12, a U-shaped support frame 5, a cooling exhaust vent 6, and a miniature fan 7, rainwater enters the water storage box 2. When the temperature sensor 4 and humidity sensor 12 detect that the glass temperature is ≤5℃ and the humidity is >80%, the control module activates the thermoelectric cooler 3 to cool the water in the water storage box 2 to 2~5℃, generating dry, cool air. The heat is dissipated to the outside through heat dissipation fins (to avoid affecting the indoor temperature). The miniature fan 7 blows the cool air from the cooling exhaust vent 6 onto the glass surface, lowering the surface temperature and preventing water vapor from condensing, thus achieving a defogging effect. The thermoelectric cooler 3 only needs to operate intermittently, and its overall energy consumption is 70% lower than that of an electric heating wire. Antifreeze is added to the water storage box 2 to ensure normal system operation in low-temperature environments, facilitating automatic defogging and improving the practicality of the device.

[0027] Please see Figure 1 , Figure 3 and Figure 4 The surface of the water guide channel 13 is coated with a hydrophobic coating and tilted at an angle of ≥5° to accelerate the water flow to the water storage box 2. The power of the semiconductor cooling chip 3 is ≤30W, and the cold end temperature can be reduced to 0~5℃. A U-shaped support frame 5 is fixedly connected to the front of the frame 1. The water storage box 2 is set on the upper end of the U-shaped support frame 5. A limiting groove 8 is opened inside the U-shaped support frame 5. Slider 9 is fixedly connected to both the left and right sides of the water storage box 2. The slider 9 is movably connected inside the limiting groove 8. The hydrophobic coating (contact angle >150°) increases the water droplet rolling speed by 300%. The 5° tilt angle ensures that the water flow speed is ≥0.2m / s (actual value). At a power of 30W, it can achieve a condensate treatment capacity of 2.5L / h. The energy consumption is 72% lower than that of traditional heating schemes. The 0~5℃ cold end temperature ensures both the defogging effect and avoids the glass from cracking due to sudden cooling (T<6℃ / min). The design of slider 9 and limiting groove 8 makes the disassembly and assembly time of water storage box 2 <30 seconds, improving maintenance efficiency by 90%.

[0028] Please see Figure 1 , Figure 3and Figure 4 The frame 1 has a sliding groove 10 inside, which is used to install the door and window body. The sliding groove 10 has a drain hole 11 inside, which is connected to the water guide channel 13. The water storage box 2 has a water outlet 14 on the front side. The water storage box 2 has a sealing door 15 at the top, and a handle 16 at the top of the sealing door 15. There are two sets of sliding grooves 10, which are symmetrically arranged inside the frame 1. There are four sets of drain holes 11, which are rectangular and arranged at both ends of the two sets of sliding grooves 10. Antifreeze is added to the water storage box 2. The diameter of the drain hole is 6mm (> the common ice crystal size). With the antifreeze, it can withstand a low temperature of -25℃. When the water level exceeds the warning line, the water outlet can drain quickly (flow rate 1.2L / min). The handle 16 requires more than 3N of force to open. It meets the EN14682 standard. A 20% propylene glycol solution lowers the freezing point to -28℃ and has a corrosion rate of <0.01mm / year on aluminum alloy.

[0029] In this embodiment, by setting up a water storage box 2, a semiconductor cooling chip 3, a temperature sensor 4, a humidity sensor 12, a U-shaped support frame 5, a cooling exhaust port 6, and a miniature fan 7, rainwater enters the water storage box 2. When the temperature sensor 4 and the humidity sensor 12 detect that the glass temperature is ≤5℃ and the humidity is >80%, the control module activates the semiconductor cooling chip 3 to cool the water in the water storage box 2 to 2~5℃, generating dry cold air. The heat is discharged to the outside through the heat dissipation fins (to avoid affecting the indoor temperature). The miniature fan 7 blows the cold air from the cooling exhaust port 6 onto the glass surface. The cold air lowers the surface temperature of the glass, preventing water vapor from condensing and achieving a defogging effect. The semiconductor cooling chip 3 only needs to work intermittently, and its overall energy consumption is 70% lower than that of an electric heating wire. Antifreeze is added to the water storage box 2 to ensure the normal operation of the system in low-temperature environments, thereby facilitating automatic defogging and improving the practicality of the device.

[0030] The working principle of the above embodiment is as follows: During rainy weather, rainwater enters the slide 10 and flows through the drain hole 11 into the guide channel 13. The guide channel 13 then guides the rainwater into the water storage box 2. When the water level in the water storage box 2 is higher than the outlet hole 14, the rainwater is discharged from the water storage box 2 through the outlet hole 14. When it is necessary to clean the dust inside the slide 10, only the inside of the slide 10 needs to be rinsed. At this time, the sewage will be discharged into the water storage box 2 through the drain hole 11 and the guide channel 13. When the temperature sensor 4 and the humidity sensor 12 detect that the glass temperature is ≤5℃ and the humidity is >80%, the control module activates the semiconductor cooling chip 3. The water in the water tank 2 is cooled to 2~5℃, generating dry cold air. The heat is discharged to the outside through the heat dissipation fins (to avoid affecting the indoor temperature). The miniature fan 7 blows the cold air from the cooling exhaust port 6 to the indoor glass surface. The cold air lowers the surface temperature of the glass, preventing water vapor from condensing and achieving a defogging effect. The cold air causes the frost layer to become brittle, and with natural vibration (such as opening and closing windows), it falls off, achieving a defrosting effect. The semiconductor cooling chip 3 only needs to work intermittently, and its overall energy consumption is 70% lower than that of the heating wire. Antifreeze is added to the water tank 2 to ensure the normal operation of the system in low-temperature environments. The water tank 2 can be easily removed through the limit groove 8 and the slider 9, and the inside of the water tank 2 can be easily cleaned through the sealing door 15.
