Abstract

The invention provides an air exhaust device for a ceiling-mounted air conditioner indoor unit, comprising an indoor unit casing, an air outlet, an air inlet, an air guide blade and a control device, wherein: one or more sides of the indoor unit casing There is an exhaust port, and flanges are fixed around it. There are two exhaust baffles of the same size in the exhaust port, and the exhaust port is completely blocked. One end of the two exhaust baffles is supported on the It is connected to the support of the casing, and the other ends are respectively provided with two linkage gears with right angles in opposite directions of rotation. The gears mesh with the gears of the motor shaft of the stepping motor fixed on the casing. Connection, the exhaust port is connected to the outdoor air duct. The beneficial effect is that the structure enables the air conditioner to have the function of replacing the fresh air. Since the indoor unit exhaust device conducts air exchange through the air duct to exhaust air, the oxygen content of the indoor air is increased, the harmful gas is reduced, the indoor air is fresh, and the air is improved. human health.

Description

technical field [0001] The invention relates to an exhaust device for a ceiling-mounted four-outlet air-conditioning indoor unit, in particular to an indoor-unit exhaust device for a ceiling-absorbing air-conditioning room with an exhaust function. Background technique [0002] With the growth of my country's economic strength and the improvement of people's living standards, room air conditioners have been popularized in general families. The basic working principle of ordinary room air conditioners is to adjust the temperature of local areas through gas heat exchange. In order to ensure the temperature adjustment effect, the environment is required to be closed, resulting in the continuous increase of indoor dust, smoke, bacteria, viruses, and exhaust gas, and the continuous decrease of oxygen content. Air quality is getting worse. Especially the recent use of various new building materials, a large amount of volatile organic compounds are emitted, which makes the types o...
