Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, specifically relating to an energy-saving door and window with indoor and outdoor heat exchange function. Background Technology

[0002] With the continuous development of building energy-saving technologies, doors and windows, as an important part of the building envelope, have a significant impact on the overall energy consumption of the building. Traditional door and window designs mainly focus on heat insulation, sound insulation, and sealing performance, but they are significantly insufficient in terms of indoor and outdoor air exchange. Especially in modern buildings, in order to keep the indoor air fresh, it is usually necessary to open windows for ventilation, but this will lead to indoor and outdoor heat exchange and increase the energy consumption of air conditioning or heating, especially under extreme climatic conditions (such as high temperatures in summer or low temperatures in winter), this problem is particularly prominent.

[0003] While existing heat exchange window and door technologies have achieved heat exchange between indoor and outdoor air to a certain extent, they still have the following problems: low heat exchange efficiency. The design of existing heat exchangers is usually quite simple, with air inlets and outlets directly opened on the window. However, the distance between the air inlets and outlets is small, which makes it easy for the air entering the room to mix with the air about to be exhausted to the outside, resulting in low heat exchange efficiency. Therefore, this application proposes an energy-saving window and door with indoor and outdoor heat exchange function. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an energy-saving door and window with indoor and outdoor heat exchange function, aiming to solve the technical problem of low heat exchange efficiency of existing doors and windows.

The first slot 8 communicates with the first air duct 6, and the second slot 9 communicates with the second air duct 7. A sealing plate 11 is fixed at the center of the interior of the bottom frame of the window frame 1. A second partition plate 12 is installed between the sealing plate 11 and the two ends of the interior of the bottom frame of the window frame 1, dividing the interior of the sealing plate 11 and the two ends of the interior of the bottom frame of the window frame 1 into a third air duct 13 and a fourth air duct 14. The third air duct 13 communicates with the first air duct 6 in the adjacent vertical frame of the window frame 1, and the fourth air duct 14 communicates with the second air duct 7 in the adjacent vertical frame of the window frame 1. A fan 15 is installed on the end of the second partition plate 12 facing the sealing plate 11, allowing air to pass through the first air duct. 6. The second air duct 7, the third air duct 13, and the fourth air duct 14 are installed. The air guide hood 2 faces the indoor side and installs the window frame 1 at the window of the house. Under the separation of the sealing plate 11 inside the bottom frame of the window frame 1, the third air duct 13 and the fourth air duct 14 at both ends inside the bottom frame of the window frame 1, together with the first air duct 6 and the second air duct 7 inside the vertical frame of the window frame 1, cooperate with the first slot 8 and the second slot 9 to establish two ventilation channels connecting the indoor and outdoor. A pair of fans 15 inside the bottom frame of the window frame 1 are activated in reverse. One fan 15 draws air along the third air duct 13 towards the fourth air duct 14, and the other fan 15 draws air along the fourth air duct 14 towards the third air duct 13. Outdoor air can enter the room through one of the ventilation channels, and indoor air can be discharged to the outside through the other ventilation channel, thereby replacing the indoor air and achieving the purpose of heat exchange between the indoor and outdoor, making the indoor air fresh.

[0023] In a further embodiment, a filter element 16 is embedded in the bottom edge of the window frame 1 facing the third air duct 13. The filter element 16 filters the air passing through the third air duct 13. Specifically, the filter element 16 includes a second cover plate 17 embedded in the side wall of the bottom edge of the window frame 1 and a housing 18 fixed on the second cover plate 17 and embedded in the third air duct 13. The outer wall of the housing 18 is in contact with the inner wall of the third air duct 13. Both ends of the housing 18 are through-hole. A mesh cylinder 19 is installed inside the housing 18. The open end of the mesh cylinder 19 faces away from the fan 15. During the process of outdoor air entering the room through the first air duct 6, the third air duct 13, the fourth air duct 14 and the second air duct 7, the mesh cylinder 19 can filter and collect dust in the air to prevent dust from entering the room and reducing the indoor air quality.

[0024] Furthermore, a first cover plate 3 is installed on the side of the bottom frame of the window frame 1 facing the fourth air duct 14. Both ends of the first cover plate 3 and the second cover plate 17 are provided with protruding plates 20. The protruding plates 20 are attached to the side of the bottom frame of the window frame 1 and bolted together. After the first cover plate 3 is removed from the window frame 1, the fan 15 can be assembled and maintained. After the second cover plate 17 is removed from the window frame 1, the housing 18 can be pulled out of the third air duct 13 to clean the mesh cylinder 19.

[0025] In a further embodiment, an air guide hood 2 is provided on the side of the vertical frame of the window frame 1 facing the second air duct 7. The interior of the air guide hood 2 is connected to the second air duct 7 through the second slot 9, and the air guide hood 2 has openings distributed on both sides of the window frame 1. The cross-section of the air guide hood 2 is triangular. Since the first slot 8 and the second slot 9 are distributed on the vertical frame of the window frame 1, and with the air guide hood 2 and the openings on the air guide hood 2 distributed on both sides of the window frame 1, air can enter or exit the room from both sides of the window frame 1, minimizing the mixing between the entering and exiting indoor air, greatly improving the efficiency of indoor and outdoor heat exchange, and reducing energy consumption to achieve the purpose of energy saving.

[0026] Furthermore, a second partition net 10 is provided inside the first slot 8 to prevent outdoor mosquitoes from entering the first airway 6, and a first partition net 4 is provided at the opening of the air guide hood 2 to prevent indoor impurities from entering the second airway 7.

[0027] Working principle: In use, the air guide hood 2 faces the interior and assembles the window frame 1 at the window of the house. Under the separation of the sealing plate 11 inside the bottom frame of the window frame 1, the third air passage 13 and the fourth air passage 14 at both ends inside the bottom frame of the window frame 1, together with the first air passage 6 and the second air passage 7 inside the vertical frame of the window frame 1, cooperate with the first slot 8 and the second slot 9 to establish two ventilation channels connecting the interior and exterior for heat exchange. Specifically, a pair of fans 15 inside the bottom frame of the window frame 1 are activated in reverse. One fan 15 draws air along the third air passage 13 towards the fourth air passage 14, and the other fan 15 draws air along the fourth air passage 14 towards the interior. Air is drawn in towards the third air duct 13, allowing outdoor air to enter the room through one of the ventilation channels and indoor air to exit the room through the other ventilation channel, thus achieving the purpose of heat exchange between the indoor and outdoor environments. Since the first slot 8 and the second slot 9 are distributed on the vertical frame of the window frame 1, and with the addition of the air guide hood 2 and the openings on the air guide hood 2 facing both sides of the window frame 1, air can enter or exit the room from both sides of the window frame 1, minimizing the mixing between the incoming and outgoing indoor air, greatly improving the efficiency of heat exchange between the indoor and outdoor environments, and reducing energy consumption to achieve the purpose of energy saving.
