Abstract

A purification window embedded with a ventilation system, including: a window frame, and a double-layered glass window unit arranged in the window frame. An outdoor window screen roll and an indoor window screen roll are arranged at a left stile and a right stile, respectively. An upper middle position and a lower middle position of the double-layered glass window unit are respectively in rotational connection with a top rail via an upper shaft and a bottom rail via a lower shaft. The ventilation system includes: an air supply chamber and an exhaust chamber, both of which provided therein with T-shaped air dampers and fans. Both external edges of the outdoor window screen roll and the indoor window screen roll are provided with magnetic tapes configured for fixation connection with the upper shaft and the lower shaft.

a second rainproof grille ( 5 b ) is arranged at an exhaust port ( 20 ) at an outdoor side of the exhaust chamber ( 12 ), a second T-shaped air damper ( 17 a ) in connection with a second electromagnetic actuator ( 6 b ) is arranged in the exhaust chamber ( 12 ); an exhaust fan ( 7 b ) is arranged in the exhaust chamber ( 12 ), wherein, an air inlet of the exhaust fan ( 7 b ) is arranged at an indoor side of the exhaust chamber ( 12 ), and an air outlet of the exhaust fan ( 7 b ) is provided therein with a filter ( 8 );
a left accommodation box ( 18 a ) is arranged at a left side of the left stile ( 3 c ) and is configured for accommodating the outdoor window screen roll ( 4 a ), and a right accommodation box ( 18 b ) is arranged at a right side of the right stile ( 3 d ) and is configured for accommodating an indoor window screen roll ( 4 b ); both external edges of the outdoor window screen roll ( 4 a ) and the indoor window screen roll ( 4 b ) are provided with magnetic tapes ( 22 ) configured for fixation connection with the upper shaft ( 1 a ) and the lower shaft ( 1 b ); and
the purification window further comprises a controller ( 21 ), and the controller ( 21 ) is configured for electric connection with the first electromagnetic actuator ( 6 a ), the second electromagnetic actuator ( 6 b ), an indoor multi-parameter sensor ( 14 ), an outdoor multi-parameter sensor ( 15 ), the blower ( 7 a ), the exhaust fan ( 7 b ), an indicator light, and a buzzer.

2 . The purification window according to claim 1 , wherein the controller ( 21 ) is an S7-200 PLC controller.

3 . The purification window according to claim 1 , wherein the indoor multi-parameter sensor ( 14 ) comprises: a CO 2 sensor, a CO sensor, a PM2.5 sensor, and a formaldehyde sensor; the outdoor multi-parameter sensor ( 15 ) comprises: a rainfall sensor, a wind speed sensor, and a PM2.5 sensor; and a rain baffle ( 16 ) is arranged above the outdoor multi-parameter sensor ( 15 ).

4 . The purification window according to claim 1 , wherein the double-layered glass window unit is filled therein with a dry gas ( 9 ), and a desiccant ( 10 ) is disposed at a bottom of the double-layered glass window unit.

5 . The purification window according to claim 1 , wherein both the first rainproof grille ( 5 a ) and the second rainproof grille ( 5 b ) adopt ventilation and rainproof louvers.

6 . A ventilation method using the purification window according to claim 1 , comprising:
a. a natural ventilation mode of the window unit, wherein the natural ventilation mode of the window unit comprises the following steps:
controlling, by the controller, the first electromagnetic actuator ( 6 a ) and the second electromagnetic actuator ( 6 b ) to close the first T-shaped air damper ( 17 a ) and the second T-shaped air damper ( 17 b ), and simultaneously turning off, by the controller, the blower ( 7 a ) and the exhaust fan ( 7 b ), manually rotating and opening the window unit and unfolding the indoor window screen roll and the outdoor window screen roll, and fixing each of the magnetic tapes ( 22 ) of the indoor window screen roll and the outdoor window screen roll to the upper shaft and the lower shaft, whereby realizing the natural ventilation of the window unit, when it is determined by the controller that at least one of the indoor CO 2 , CO, PM2.5, and formaldehyde concentrations detected by the indoor multi-parameter sensor ( 14 ) is higher than a preset value and the PM2.5 concentration detected by the outdoor multi-parameter sensor ( 15 ) is lower than the preset value, a sunny day is detected by a rainfall sensor at outdoor, and the indicator light flashes and the buzzer prompts;
