The present application will be further described below with reference to the drawings:
The window unit is a double-glazed unit which adopts an indoor side glass 2a and an outdoor side glass 2b. A high-strength and high-air-tight composite adhesives is applied around the two layers of glass to bond and seal the two layers of glass together with sealing strips 2c and glass strips. A dry gas 9 is filled in the middle and a desiccant 10 is placed at the bottom, thus ensuring the dryness of the air between the two layers of glass.
The purification window of the present application is equipped with a roller type magnetic window screen. Invisible screen window rolls are installed at the corresponding indoor and outdoor positions. The vertical shafts of the purification window are made of magnetic materials. The window screens of the roller type arranged in a right accommodation box 18b and a left accommodation box 18a can be drawn out separately and outer edges of the window screen rolls can be in fixed connection with the vertical shafts via magnetic tapes 22 at the outer edges. The window screen includes a right part and a left part, the two parts of the window screen are drawn out from respective window screen rollers of the right accommodation box 18b and the left accommodation box 18a and are combined at a middle to ensure comprehensive mosquito prevention. The accommodation boxes configured for accommodating the screen window rolls are arranged in a concaved manner beside the left stile 3c and the right stile 3d, respectively, and both the accommodation boxes are arranged vertically. The accommodation boxes are respectively arranged at positions of an outdoor left side and an indoor right side, respectively. The outdoor window screen roll 4a and the indoor window screen roll 4b are respectively arranged inside the left accommodation box 18a and the right accommodation box 18b. In order to ensure the convenience and aesthetics of the screen window when the window unit is turned to open, the main part of the shaft of the screen window roll is received inside the window frame, and only the screen window handrail is exposed. In this way, when the screen windows are retraced, no additional space is taken up, and the anti-corrosion effect and the dust-proof effect can be achieved.
A specially designed mechanical ventilation system is arranged above the window unit and does not rotate along with the window unit. The ventilation system has three chambers, that is, an air supply chamber 11, an exhaust chamber 12, and an air isolation chamber 13. Two blowers 7a of the same model are arranged in the air supply chamber 11, and two exhaust fans 7b of the same model are arranged in the exhaust chamber 12. In order to prevent the air flows from being chaotic, the air isolation chamber 13 is configured to separate the blowers 7a of the air supply chamber 11 from the exhaust fans 7b of the exhaust chamber 12, thus making the air flow unidirectionally. The fan ducts arranged in the proximity of the outdoor side are provided therein with filters 8. Outdoor air enters the room through the first rainproof grille 5a, and the indoor return air is discharged to the outside through the second rainproof grille 5b.
The ventilation system is equipped with a first electromagnetic actuator 6a and a second electromagnetic actuator 6b, which are configured to mechanically drive the ventilation system to open and close by receiving signals from the controller 21. The indoor multi-parameter sensor 14 comprises: a CO2 sensor, a CO sensor, a PM2.5 sensor, and a formaldehyde sensor, which are located at corresponding positions at an indoor side of the air isolation chamber 13. The outdoor multi-parameter sensor 15 comprises: a rainfall sensor, a wind speed sensor, and a PM2.5 sensor, which are located at corresponding positions at an outdoor side of the air isolation chamber 13.
