Description

Simple air door type defroster Technical Field The utility model relates to the technical field of defrosters, in particular to a simple air door type defroster. Background The windshields of the passenger car are easy to frost in cold winter, so that drivers cannot see the road conditions clearly and traffic accidents occur. This requires that the passenger car windshield must be defrosted quickly. The existing defroster often needs to open a defrosting air door to enable warm air to be blown to a windshield at maximum power and maximum air quantity, so that a defrosting effect is achieved. However, once the motor of the defrosting air door fails, the defrosting function cannot be realized, and the use safety cannot be ensured. And defrosting equipment in the prior art is complex and has high cost. Disclosure of utility model In order to solve the technical problems, the utility model provides the simple air door type defroster which is simple in structure, achieves maximum air quantity defrosting through a simple structure, and can defrost according to a part of air quantity under other functional modes, so that the driving safety is ensured to the greatest extent. Specifically, the utility model discloses a simple air door type defroster, which comprises: The housing assembly is provided with a defrosting opening and an air outlet, the defrosting opening faces towards the vehicle window, and the air outlet faces towards the interior of the vehicle; The air outlet assembly comprises a heating assembly and a fan, wherein the heating assembly and the fan are arranged in the shell assembly, the heating assembly is used for heating, and the fan is used for air outlet; The air door is rotatably arranged in the shell assembly and used for shielding the air outlet.
