DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present application will be further described below with reference to the drawings:

[0029] FIGS. 1-5 show structural views of an anti-mosquito and anti-haze purification window embedded with a ventilation system. In the figures, the purification window comprises: a window frame, layers of glasses, filters 8, the ventilation system, blowers 7a, exhaust fans 7b, and window screen rolls 4a, 4b. A main body of the purification window includes a rectangular arrangement formed by the ventilation system, a top rail 3a, a bottom rail 3b, a left stile 3c, and a right stile 3d. The window unit is rotatable around a vertical axis via an upper shaft 1a and a lower shaft 1b. Both the upper shaft 1a and the lower shaft 1b are made of strong magnetic materials, and the upper and the lower ends of the outer edges of the window screen rolls along the direction of the shafts can be fixed by the magnetic materials after the window screen rolls are unfolded.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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 CO.sub.2 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.

[0034] FIG. 4 is a top view of the ventilation system in an on-state according to an embodiment of the present application. When it is detected by the indoor multi-parameter sensor 14 that at least one of the indoor CO.sub.2, CO, PM2.5, and formaldehyde concentrations is higher than a preset value and it is detected by the outdoor multi-parameter sensor 15 that the PM2.5 concentration is higher than the preset value and it is a rainy day; then, the window unit is manually closed, and the ventilation system is opened, and if the wind speed monitored by the wind speed sensor is lower than a preset value, then the blower 7a and the exhaust fan 7b are started to enter a mechanical ventilation mode of the ventilation system. The first electromagnetic actuator 6a and the second electromagnetic actuator 6b are controlled by the controller to open the first T-shaped air damper 17a and the second T-shaped air damper 17b. The outdoor air enters the air supply chamber 11 through the first rainproof grilles 5a, then filtered by the filters 8 arranged at the blowers 7a and enters the indoor space; the indoor air enters the exhaust fan 7b, then filtered by the filters 8 arranged at the exhaust fans 7b and enters the exhaust chamber 12, and finally discharged to the outdoor space through the second rainproof grilles 5b.

[0035] The S7-200 PLC controller model 6ES7211-0BA23-0XB0, AC/DC/relay is a micro PLC, which is applicable for different fields and industries, particularly in automatic detection, monitoring, and control in various occasions, the S7-200 PLC controller can realize its complex control function due to its powerful functions, regardless of whether it is running in a stand-alone manner or connected into a network.

[0036] FIG. 5 is a top view of the ventilation system in an off-state according to an embodiment of the present application. When it is detected by the indoor multi-parameter sensor 14 that at least one of the indoor CO.sub.2, CO, PM2.5, and formaldehyde concentrations is higher than the preset value and it is detected by the outdoor multi-parameter sensor 15 that the PM2.5 concentration is lower than the preset value and it is a sunny day; then, the window unit is manually opened, and the ventilation system is turned off. The first electromagnetic actuators 6a and the second electromagnetic actuators 6b are controlled by the controller to push the first T-shaped air dampers 17a and the second T-shaped air dampers 17b to close the air supply ports 19 and the exhaust ports 20, thereby closing the corresponding air ducts.

[0037] FIGS. 6-7 show details of a side view of the ventilation system in the on-state and the off-state according to embodiments of the present application. A rain baffle 16 is arranged above the outdoor multi-parameter sensor 15. When the ventilation system is turned on, the first T-shaped air dampers 17a and the second T-shaped air dampers 17b are retracted towards an indoor side by the first electromagnetic actuators 6a and the second electromagnetic actuators 6b, so as to open the air supply chamber 11 and the exhaust chamber 12. When the ventilation system is turned off, the first T-shaped air damper 17a and the second T-shaped air damper 17b are pushed by the first electromagnetic actuators 6a and the second electromagnetic actuators 6b to close the air supply chamber 11 and the exhaust chamber 12.

[0038] FIG. 8 shows a top view of anti-mosquito and anti-haze embedded with the ventilation system when the window unit is opened for natural ventilation. For the natural ventilation, when the window unit is opened perpendicular to the window sill, the outdoor window screen roll 4a and the indoor window screen roll 4b are extended and in fixed connection with the upper shaft 1a and the lower shaft 1b via the magnetic tapes 22 arranged at the edges of the screen window rolls, in such condition, the window unit can be rotated counterclockwise at any angle to change the opening degree.
