Air-purifying and fresh-air system of building door window

Abstract

The invention discloses an air-purifying and fresh-air system of a building door window. The air-purifying and fresh-air system at least comprises a left air passage, a right air passage and a fresh air purifying window sill structure, wherein the left air passage and the right air passage are installed on the two side walls of a door window hole, and the fresh air purifying window sill structure is installed at the lower portion of the door window hole. The fresh air purifying window sill structure is mainly composed of a window sill structure body and a fresh air and air purifying cavity structure, wherein the window sill structure body is arranged on the outdoor side, an outer air inlet passage is formed in the middle of the window sill structure body, the fresh air and air purifying cavity structure is arranged on the indoor side, and an inner air inlet passage is formed in the middle of the fresh air and air purifying cavity structure. The fresh air and air purifying cavity structure is connected with the window sill structure body on the outdoor side through broken bridge materials into a whole, and the inner air inlet passage and the outer air inlet passage are communicated with the fresh air and air purifying cavity structure. The air-purifying and fresh-air system has the advantages that the structure is reasonable and compact, use is convenient and reliable, fresh air can be led into the system, air purifying can be achieved, pollution of harmful substances in the air to living space can be prevented, and meanwhile effective circulating between indoor air and outdoor air can be guaranteed.

Description

technical field [0001] The invention relates to an air purification and fresh air system for building doors and windows, and belongs to the technical field of ventilation and ventilation of buildings. Background technique [0002] In recent years, with the development of my country's economy, the rapid growth of urban population and the acceleration of urbanization, nearly 25 provinces and more than 100 large and medium-sized cities have appeared in varying degrees from North China to the southeast coast and even the southwest.
