Description

Technical Field

[0001] This utility model relates to the field of bidirectional flow fresh air fans, and in particular to an energy-saving and environmentally friendly bidirectional flow fresh air fan. Background Technology

[0002] A two-way flow fresh air system is a device with an independent exhaust and supply air system. It uses mechanical power to send fresh outdoor air into the room while expelling stale indoor air, thereby achieving the purpose of purifying the air and ventilating the room.

[0003] Common bidirectional flow fresh air systems typically use a filter to filter the intake air and discharge it into the room, while simultaneously using an exhaust fan to expel indoor air, thus achieving ventilation. However, they lack dust collection components and cannot adsorb and collect dust inside the fan enclosure. As a result, after prolonged use, a large amount of dust accumulates inside the fan enclosure, which not only affects the normal operation of the fan inside the enclosure but also reduces the quality of the air delivered by the fan.

[0004] Therefore, to address the lack of dust collection components in the aforementioned bidirectional flow fresh air units, which prevent the adsorption and collection of dust inside the fan protective box, an energy-saving and environmentally friendly bidirectional flow fresh air unit can be designed. A limiting seat can be used to restrict the position of the mounting frame, preventing displacement and shaking during operation. Simultaneously, a dust-collecting plate on the inner side of the mounting frame can adsorb dust inside the casing, preventing dust accumulation and sedimentation. Furthermore, pulling the pull ring can move the sealing plate and pull rod upwards, causing the mounting frame to move synchronously, facilitating the disassembly and cleaning of the mounting frame and dust-collecting plate. Utility Model Content

[0005] To overcome the common problem of two-way flow fresh air fans lacking dust collection components, which cannot adsorb and collect dust inside the fan protective box, resulting in a large amount of dust accumulating inside the fan protective box after long-term use, this not only affects the normal operation of the fan inside the protective box, but also reduces the quality of the air delivered by the fan.

[0006] The technical solution of this utility model is as follows: an energy-saving and environmentally friendly bidirectional flow fresh air unit, including a cabinet; it also includes a slot, a limiting seat, a mounting frame, a dust collection plate, connecting holes, a pull rod, a sealing plate, and pull rings.

[0007] Preferably, the limiting seat can be used to restrict the position of the mounting frame, so that it will not shift or shake during operation. At the same time, the dust suction plate on the inside of the mounting frame can absorb dust inside the chassis, preventing dust from accumulating and settling inside the chassis. Pulling the pull ring can move the sealing plate and the pull rod upward. When the pull rod moves, it will move the mounting frame synchronously, so as to facilitate the disassembly and cleaning of the mounting frame and the dust suction plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. The limiting seat can be used to restrict the position of the mounting frame, preventing it from shifting or shaking during operation.

Two pull rings 9 are symmetrically installed on the left and right ends of the top of the sealing plate 8. The position of the mounting frame 4 can be restricted by the limiting seat 3 to prevent displacement and shaking during operation. At the same time, the dust suction plate 5 on the inner side of the mounting frame 4 can absorb the dust inside the chassis 1 to prevent dust from accumulating and settling inside the chassis 1. Pulling the pull rings 9 can move the sealing plate 8 and the pull rod 7 upward. When the pull rod 7 moves, it will drive the mounting frame 4 to move synchronously, so as to facilitate the disassembly and cleaning of the mounting frame 4 and the dust suction plate 5.

[0024] Please see Figures 1-5In this embodiment, a maintenance door 10 is installed on the front side of the chassis 1. A handle 11 is connected to the front side of the maintenance door 10, and the maintenance door 10 is connected to the chassis 1 via a hinge. The maintenance door 10 can be used to protect the front side of the chassis 1, and also facilitates the opening of the maintenance door 10 by personnel to inspect and maintain the interior of the chassis 1. A partition 12 is provided inside the chassis 1, and a heat exchanger 13 is provided on the top of the partition 12. A blower 14 is provided on the right side of the heat exchanger 13, and the left end of the blower 14 is connected to the right side of the heat exchanger 13. The partition 12 can be used to support the heat exchanger 13, and the temperature of the air delivered by the blower 14 can be adjusted through the heat exchanger 13. The indoor temperature is always kept within the set value to achieve energy saving and environmental protection. A support platform 15 is installed on the upper right side of the casing 1. A filter box 16 is installed on the top of the support platform 15. An exhaust fan 17 is installed on the right side of the filter box 16. Two filter plates 18 are symmetrically installed inside the filter box 16. A top cover 19 is installed on the top of the filter box 16. The right end of the blower 14 passes through the casing 1 and connects to the filter box 16. The support platform 15 can be used to support the filter box 16. The exhaust fan 17 can draw outdoor air into the filter box 16. At the same time, the air can be filtered by the filter plates 18. The filtered air will be delivered to the heat exchanger 13 by the blower 14.

[0025] Please see Figures 1-5 In this embodiment, two conveying pipes 20 are connected to the left side of the heat exchanger 13. An air outlet 21 is installed on the left side of the casing 1 corresponding to the position of the conveying pipes 20, and the left end of the conveying pipe 20 is connected to the right end of the air outlet 21. Air inside the heat exchanger 13 can be conveyed to the air outlet 21 through the conveying pipes 20, and air at a suitable temperature can be discharged into the room through the air outlet 21 to achieve the purpose of ventilation. An exhaust fan 22 is provided inside the casing 1 corresponding to the lower side of the partition 12, and an air inlet is connected to the left side of the exhaust fan 22. 23, and the other end of the air inlet 23 is connected through to the left side of the casing 1. The air inlet 23 can be controlled by the exhaust fan 22 to draw in the indoor air. The right side of the exhaust fan 22 is connected to the exhaust pipe 24. The right side of the casing 1 is equipped with a sewage vent 25 corresponding to the position of the exhaust pipe 24. The right end of the exhaust pipe 24 is connected to the sewage vent 25. The indoor air drawn by the exhaust fan 22 can be transported to the sewage vent 25 through the exhaust pipe 24, and the air is discharged through the sewage vent 25 to achieve the effect of ventilation.

[0026] During operation, the supply fan 14, exhaust fan 17, and ventilator 22 are first started. The exhaust fan 17 draws outdoor air into the filter box 16, where it is filtered by the filter plate 18. The filtered air is then transported by the supply fan 14 to the heat exchanger 13. The heat exchanger 13 regulates the temperature of the air supplied by the supply fan 14, maintaining the indoor temperature within a set value for energy saving and environmental protection. Simultaneously, the air from the heat exchanger 13 is transported to the air outlet 21 via the delivery pipe 20, allowing appropriately sized air to be exhausted into the room for ventilation. While fresh air is being supplied, the exhaust fan 22 can be used to control the airflow. The air inlet 23 draws in indoor air and delivers it to the exhaust vent 25 through the exhaust pipe 24, thus achieving ventilation. The limiting seat 3 restricts the position of the mounting frame 4, preventing displacement and shaking during operation. The dust collection plate 5 inside the mounting frame 4 absorbs dust from the inside of the chassis 1, preventing dust accumulation. After ventilation, pulling the ring 9 moves the sealing plate 8 and the pull rod 7 upwards. The movement of the pull rod 7 moves the mounting frame 4 synchronously, facilitating disassembly and cleaning of the mounting frame 4 and the dust collection plate 5.

[0027] Through the above steps, the limiting seat 3 can be used to restrict the position of the mounting frame 4, preventing it from shifting or shaking during operation. At the same time, the dust suction plate 5 on the inner side of the mounting frame 4 can absorb dust inside the casing 1, preventing dust from accumulating and settling inside the casing 1. Pulling the pull ring 9 can move the sealing plate 8 and the pull rod 7 upwards. When the pull rod 7 moves, it will move the mounting frame 4 synchronously, so as to facilitate the disassembly and cleaning of the mounting frame 4 and the dust suction plate 5. This solves the problem of common bidirectional flow fresh air fans, which usually filter the intake air and discharge it into the room through a filter device, and exhaust the indoor air through the exhaust fan 22, which can achieve the effect of ventilation. However, they lack dust collection components and cannot absorb and collect dust inside the fan protective box. As a result, after a long period of use, a lot of dust accumulates inside the fan protective box, which not only affects the normal operation of the fan inside the protective box, but also reduces the quality of the air delivered by the fan.
