When the fan is not working, dust can easily enter the interior of the air conditioner through the air outlet, which not only affects human health but also reduces the performance of the air conditioner. In the prior art, there are generally two solutions to overcome the above problems. One is to prevent dust from entering the interior of the air conditioner by setting a baffle that can move to open or close the air outlet. However, this solution cannot solve the problem of poor stability of the air conditioner. Another solution is to install an air outlet frame in the casing that can receive the airflow from the fan and guide the airflow to the indoor environment or close the air outlet. This solution can effectively reduce the center of gravity of the whole machine and prevent dust from entering the interior of the air conditioner. However, due to the distance between the air outlet frame and the fan outlet, the airflow blown from the fan flows to the air outlet frame scatteredly, not only the gas flow rate is low, the structure of the whole machine is not compact, but also it will generate a lot of noise, which reduces the air output of the air conditioner. effects and user experience. Considering comprehensively, it is necessary to design an air guide member for the indoor unit of a cabinet air conditioner that can lower the center of gravity of the whole machine, prevent dust from falling in, and have a better air guide effect.
