Circulating ventilation automobile transom window

Abstract

The invention discloses a circular ventilation automobile transom window. Comprising a vehicle inner shell and a vehicle outer shell installed on the top of the inner shell, at least one outer circulation opening is formed in the vehicle outer shell, at least one inner circulation opening is formed in the vehicle inner shell, a ventilation cavity is formed after the vehicle inner shell and the vehicle outer shell are installed in an involution mode, and at least one circulation fan is arranged in the ventilation cavity. Through the circulating fan, external air can enter the automobile through the ventilation cavity, and air in the automobile can be exhausted out of the automobile through the ventilation cavity. The air circulation device has the advantages that air in the automobile can be exhausted out of the automobile through the circulating fan, air outside the automobile can be led into the automobile through the circulating fan to achieve the fresh air leading-in function, and therefore the requirement for external air exchange is met, the purpose of improving the air circulation effect is achieved, and the problem that the quality of air in the automobile is poor is greatly solved.

Description

technical field [0001] The invention relates to a car roof window structure, in particular to a car roof window with circulation ventilation. Background technique [0002] As everyone knows, the interior environment of a car is relatively closed, so it is necessary to ventilate the car to improve ride comfort. For this reason, existing cars are equipped with necessary roof windows, while existing conventional roof windows usually have It includes the inner shell and the outer shell that is hinged on the roof and covers the inner shell. When the interior of the car needs to be ventilated, the window formed by opening the outer shell can circulate the inside and outside air. Of course, In order to ensure the air circulation in the car, a circulating fan can also be installed at the bottom of the car's inner shell, and an air inlet and an air outlet are arranged on the car's inner shell, so that when the car's outer shell is closed, the circulating fan can be used to The air i...

[0002] As everyone knows, the interior environment of a car is relatively closed, so it is necessary to ventilate the car to improve ride comfort. For this reason, existing cars are equipped with necessary roof windows, while existing conventional roof windows usually have It includes the inner shell and the outer shell hinged on the roof and covering the inner shell. When the interior of the car needs to be ventilated, the window formed by opening the outer shell can circulate the air inside and outside. Of course, In order to ensure the air circulation in the car, a circulation fan can also be installed at the bottom of the car interior shell, and an air inlet and an air outlet are arranged on the car interior shell, so that when the car shell is closed, the circulation fan can be used to The air in the car can be circulated by using the air inlet and the air outlet, which improves the purpose of the air flow in the car. The existing structure mainly has the following problems. On the one hand, when the air needs to be circulated externally, due to the The air pressure is basically balanced. It is difficult for the air outside the car to enter the car. In fact, it can only have a limited ventilation effect but not a ventilation effect. It cannot solve the problem of poor air in the car. On the other hand, The circulating fan installed on the top of the car shell only serves to accelerate the air circulation, and the air environment problem in the car cannot be substantially solved.
