The bathroom has windows, but how to improve the lighting?

At present, the plane design scheme of brick-concrete structure apartment has been scrutinized to the extreme, and the layout has no variables. However, efforts should be made in detail design, careful consideration and continuous improvement to make the use function of residential toilets more reasonable and perfect. It is suggested that everyone must have certain knowledge of toilet safety, so that the treatment of poor lighting in the bathroom can be put in place in time. Under the guidance of this idea, GB50096- 1999 "Code for Residential Design" stipulates that the door of the bathroom should be at the lower part, with fixed louvers with an effective cross-sectional area of not less than 0. 02 or a gap of not less than 30mm from the ground; Exhaust ventilation duct with backflow prevention structure should be set, and the location and conditions for installing exhaust machine should be reserved; Natural ventilation pipes should be located opposite the window or air inlet to ensure the ventilation of the whole room.

In practical application, the relatively hidden bathroom door should be set with 100 page, otherwise it will easily cause sound interference, and when it is not hidden, the door leaf can only be sewn below. Usually, the layout of the exhaust duct only pays attention to aesthetics, and it is randomly arranged at the front end of the bathroom or behind the door, resulting in short circuit of ventilation, inability to exhaust dirty air at the bathroom end, small effective cross section of the brick duct, rough inner wall of the duct, complicated masonry process and frequent blockage, which is difficult to dredge; Cement mortar air duct does not solve the crosswind problem. Therefore, it was popular to use PVC pipes as air ducts for some time, but in actual use, crosstalk, crosswind and condensation reflux were not effective.

How to improve the bathroom with windows but poor lighting? Choose transparent decorative materials. The use of materials with strong permeability such as glass and metal can increase reflection and permeability. Then how to solve the problem of poor lighting in the bathroom? We try to reduce the use of heavy color system. A room with poor light in the bathroom will look dark and obscure. When decorating this kind of room, you should try to use light-colored floor, tiles and other decoration materials, which have a reflective feeling and can adjust the dark light in the room. Small apartment space does not necessarily need heavy color system. Local use of heavy colors has the effect of emphasis and contrast. Compared with the light color system, it can increase the layering of space. The kitchen is decorated with local heavy colors, and then with a large area of light-colored floor tiles, so that the living room space looks tall without losing its focus.

At present, the brick wall (wall) of standard drawing 98J3 is adopted: the variable pressure exhaust duct made of barbed wire, other non-combustible fibers and cement mortar. With patented technology, the cross section of the air inlet is changed, and the ventilation performance and use effect are greatly improved. If it is supplemented by mechanical forced ventilation, such as setting a separate exhaust fan or using an exhaust fan such as Yuba, the exhaust facilities should still be as close as possible to the air outlet of the air duct. If possible, priority should still be given to the layout of the external wall of the bathroom as a natural ventilation and lighting bathroom with windows.
