Abstract
Description
Technical Field
[0001] This utility model relates to a fresh air door and window. Background Technology
[0002] In recent years, "fresh air doors and windows" have emerged, integrating fresh air functionality into the door and window structure. These products utilize the internal cavity of the door and window frame as an airflow channel, eliminating the need for additional drilling or ductwork, and achieving ventilation while preserving the original structural integrity of the building. However, existing fresh air doors and windows still have significant technical shortcomings.
[0003] For example, although some products have fans (i.e. blowers) installed in the passageway to actively bring outdoor air into the room, they lack an effective airflow control mechanism: after the fan stops, the passageway remains open, which can easily lead to heat loss in winter, cold leakage in summer, and even cause rainwater, dust or mosquitoes to flow back into the room through the passageway. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a fresh air door and window.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A new type of ventilation door and window includes a frame and a cover plate detachably connected to the frame. The frame has an internally connected air supply channel and an air intake channel. The cover plate or the frame has a vent communicating with the air supply channel or the air intake channel. The air supply channel communicates with the interior, and the air intake channel communicates with the exterior. At least one of the air intake channel and / or the air supply channel is provided with a blower, and at least one of the air intake channel and / or the air supply channel is provided with a damper. The damper is configured to switch between a ventilation state and a closed state to control the airflow of the corresponding channel.
[0007] In some embodiments, the air valve includes a drive motor and a baffle plate, the baffle plate being driven by the drive motor to switch between a ventilation state and a closed state.
[0008] In some embodiments, the blower and the air valve are linked for control: when the blower is running, the air valve switches to the ventilation state; when the blower stops running, the air valve switches to the closed state.
[0009] In some embodiments, the frame is made of a hollow profile, and the hollow profile has a plurality of integrally formed longitudinal partitions inside. The longitudinal partitions divide the inner cavity of the profile into several sub-cavities extending along the longitudinal direction of the frame. Perforations are opened on the side wall of the frame along the direction intersecting the longitudinal direction. The perforations connect at least two sub-cavities. A plug is provided in the sub-cavity corresponding to the perforation. The perforations and plugs together form the air inlet channel and / or air outlet channel.
[0010] In some embodiments, the plug is made of an elastic material.
[0011] In some embodiments, the frame is provided with a removable cover plate on the side facing the interior, the cover plate is provided with the vent, and the air supply channel is connected to the interior through the vent.
[0012] In some embodiments, the frame is provided with a removable cover plate on the side facing the outside, the cover plate is provided with the vent, and the air intake channel is connected to the outside through the vent.
[0013] In some embodiments, the blower includes an air inlet and an air outlet that are connected to each other, and a fan disposed between the air inlet and the air outlet, wherein the air inlet is connected to the outside and the air outlet is connected to the inside.
[0014] In some embodiments, the air valve is disposed at the air inlet end or the air outlet end.
[0015] In some embodiments, the blower further includes a negative ion generator, which is disposed at the air delivery end.

[0023] Reference Figures 1 to 4 A new type of ventilation door and window, wherein the frame 10 is a rectangular or irregularly shaped frame for embedding in a wall. The interior of the frame 10 is provided with an interconnected air supply duct 20 and an air intake duct 30. The air supply duct 20 is connected to the interior and is used to blow outdoor air into the interior; the air intake duct 30 is connected to the outside and is used to introduce fresh outdoor air.
[0024] In some embodiments, the air intake channel 30 is provided with a blower 40, which generally refers to a device capable of driving airflow. Its core component is a fan 43, and it can also integrate functional modules such as filtration, sterilization, humidification, or negative ion generation. The blower 40 is fixedly installed inside the air intake channel 30 of the frame 10. The blower 40 is used to blow air, bringing outdoor air into the room. The air supply channel 20 is provided with a damper 50. In other embodiments, the blower 40 and / or the damper 50 may also be installed in the same channel, or only one of them may be installed. The damper 50 is configured to switch between a ventilation state and a closed state to control the airflow of the corresponding channel, thereby achieving on-demand ventilation or airtight insulation, improving the problems of indoor heat loss in winter, cold air leakage in summer, and rainwater, dust, or mosquitoes flowing back into the room through the channel.
[0025] The frame 10 is detachably connected to a cover plate 70. Removing the cover plate 70 facilitates the installation of the air valve 70 and the blower 40 into the air supply duct 20 and / or the air inlet duct 30. The cover plate 70 can be installed on the side of the frame 10 facing indoors or outdoors, or it can be installed on the side of the frame 10 parallel to the outdoors and pointing towards the indoors.
[0026] The air valve 50 can be manually switched or driven by the drive motor 51. For example, if the air valve 50 is set at the end of the air supply duct 20 near the room, the baffle plate 52 of the air valve 50 is slidably connected to the frame 10, and at least a part of the baffle plate 52 is exposed to the room, the state of the air valve 50 can be switched by manually pushing the baffle plate 52 exposed to the room, so that the air valve 50 can switch between the ventilation state (baffle plate open) and the closed state (baffle plate closed).
[0027] In some embodiments, the air valve 50 includes a drive motor 51 and a baffle plate 52. The baffle plate 52 is driven by the drive motor 51 and can switch between a ventilation state (baffle plate open) and a closed state (baffle plate closed). Specifically, the damper 50 also includes a damper housing 53, which has a damper vent 531 and a damper outlet 532. The damper vent 531 and the damper outlet 532 are connected. The drive motor 51 is fixedly connected to the frame 10 or the damper housing 53. The lead screw 511 of the drive motor 51 is movably connected to the baffle plate 52 by a thread, and the baffle plate 52 is slidably connected to the frame 10 or the damper housing 53. Under the drive of the drive motor 51, the baffle plate 52 can slide in the longitudinal direction. When the baffle plate 52 is in the closed state, the baffle plate 52 blocks the damper vent 531 or the damper outlet 532 to prevent outdoor air from entering the room through the damper 50. When the baffle plate 52 is in the ventilation state, the baffle plate moves away from the damper vent 531 or the damper outlet 532 so that outdoor air can enter the room through the damper 50.
[0028] In some embodiments, the drive motor 51 may be a micro stepper motor, a servo motor, or an electromagnetic drive device, which can automatically open and close in response to control signals.
[0029] In some embodiments, the blower 40 and the air valve 50 are controlled in a linked manner. Specifically, when the blower 40 is running, the control system synchronously controls the air valve 50 to switch to the ventilation state; when the blower 40 stops running, the air valve 50 switches to the closed state. This linkage can be achieved through a preset program, relay circuit, intelligent controller (such as a microcontroller or PLC), or wireless communication module, effectively preventing the exchange of outdoor and indoor air after the fan stops.
[0030] In some embodiments, the frame 10 is constructed of a hollow profile (such as aluminum alloy or PVC profile), and the hollow profile has multiple integrally formed longitudinal partitions 101 inside, dividing the inner cavity of the profile into several sub-cavities 102 extending along the length direction (i.e., longitudinally) of the frame. Perforations 103 are formed on the sidewalls of the profile along a direction intersecting the longitudinal direction; the perforations 103 connect at least two sub-cavities 102; plugs 60 are provided in the sub-cavities 102 corresponding to the perforations 103, and the plugs 60 are sealed to the inner wall of the sub-cavity 102. The air inlet channel 30 and / or air outlet channel 20 are formed by sealing the perforations 103 on both sides. This structure makes full use of the space within the profile itself to construct airflow paths with the plugs 60, eliminating the need for additional ductwork, saving space, and facilitating integration.
[0031] In some embodiments, the plug 60 is cylindrical, and further, the plug 60 is made of an elastic material, such as silicone, thermoplastic elastomer (TPE), or soft PVC. This elastic material not only facilitates embedding into the sub-cavity 102 during installation, but also maintains good sealing performance during temperature changes, vibration, or long-term use, preventing air in the channel from flowing to other parts of the frame and affecting the air supply effect.
[0032] In some embodiments, the frame 10 has a removable cover 70 on the side facing the interior. The cover 70 has a vent 71, which communicates with the air supply duct 20. The air supply duct 20 communicates with the interior through the vent 71, allowing outdoor air to enter the interior through the air supply duct 20 and the vent 71. The cover 70 can be fixed by a snap-fit 703, magnetism, or screws, facilitating periodic removal by the user for cleaning the interior of the duct.
[0033] In some embodiments, the cover plate 70 includes a front panel 701 and snap-fit plates 702 located on both sides of the front panel 701. The snap-fit plates 703 and the vent 71 are disposed on the snap-fit plates 702, and the cover plate 70 is detachably connected to the frame 10 via the snap-fit plates 703. The orientation of the vent 71 intersects with the direction from the outside to the inside. This arrangement facilitates the concealment of the vent 71 and avoids direct airflow, reducing disturbance to the indoor air.
[0034] In some embodiments, the frame 10 has a removable cover plate 70 on the side facing the outside. The cover plate 70 has a vent 71, which communicates with the air intake channel 30. The air intake channel 30 is connected to the outside through the vent 71 to introduce outdoor air. The cover plate 70 is removable, allowing users to periodically remove it for cleaning the inside of the channel.
[0035] In some embodiments, the blower 40 includes an air inlet 41 and an air outlet 42 that are interconnected, and a fan 43 disposed between the air inlet 41 and the air outlet 42. Specifically, the blower 40 includes a main blower housing 401, with the air inlet 41 and the air outlet 42 respectively disposed at both ends of the main blower housing 401. The fan 43 is fixedly connected inside the main blower housing 401. The air inlet 41 communicates with the outside (via the air inlet channel 30 and the vent 81), and the air outlet 42 communicates with the inside (via the air outlet channel 20 and the vent 71). When the fan 43 is running, it draws in outdoor air from the air inlet 41 and delivers it into the room from the air outlet 42, achieving unidirectional fresh air supply.
[0036] In some embodiments, the air valve 50 is disposed at the air inlet end 41 or the air outlet end 42. For example, the air valve 50 may be installed at the air inlet end 41 to cut off the entry of outdoor air in the non-operating state, preventing rainwater, dust, or cold air from seeping in; in other embodiments, the air valve 50 may also be disposed at the air outlet end 42 to prevent indoor warm air from leaking out. By arranging the air valve at the end position of the blower, direct control of the airflow inlet or outlet can be achieved, improving the system's sealing performance and energy efficiency.
[0037] In some embodiments, the blower 40 further includes a negative ion generator 44. The negative ion generator 44 is a high-voltage corona discharge module, installed inside the air supply end 42, located downstream of the fan 43. When the fan 43 is running, the airflow passes through the electrode tip area of the negative ion generator 44, generating a large number of negative oxygen ions (concentration up to 1×10⁻⁶). 6 ions / cm 3 The above-mentioned particles combine with PM2.5, bacteria, viruses, or odor molecules suspended in the air, causing them to settle or become inactive. The negative ion generator 44 is powered by a low-voltage DC power supply (such as 12V / 24V) and shares a control circuit with the fan 43, ensuring it is only activated when supplying air to avoid excessive ozone production. This design achieves integrated air purification and fresh air supply without increasing additional volume.
[0038] The above embodiments do not limit the scope of protection of this invention. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this invention are still within the scope of this invention.
