Description

Technical Field

[0001] The utility model relates to the technical field of defrosters, in particular to a water-electricity integrated defroster for a passenger car. Background Art

[0002] In winter, when outdoor temperatures are relatively low, frost easily forms on bus windshields, severely affecting the driver's field of vision and posing a driving safety hazard. The defroster is connected to the bus engine's cooling circulation system. It exchanges heat between the system's high-temperature coolant and the airflow through a heat exchanger tank, generating hot air that is evenly blown through the defrost pipe to the inside of the windshield, achieving panoramic defrosting.

[0003] After checking the publication number: CN221272928U, a bus water-electric integrated defroster is disclosed. This technology discloses "a bus water-electric integrated defroster, comprising a shell, an air inlet is provided at the bottom of the shell, wherein the interior of the shell is divided from top to bottom into a heat exchange chamber, a fan chamber and a heating chamber by a partition arranged horizontally at intervals; a water inlet and a water outlet located below the water inlet are provided on the side wall of the heat exchange chamber, a heat exchange pipe connected with the water inlet and the water outlet is provided inside the heat exchange chamber; a fan is provided inside the fan chamber, the air inlet of the fan is connected with the heat exchange chamber, and the air outlet of the fan is connected with the heating chamber; a PTC heating sheet is horizontally provided inside the heating chamber; a plurality of cylindrical air outlets connected with the heating chamber are provided on the top of the shell, and a heating wire is wound around the interior of the cylindrical air outlet through a plurality of horizontally supported pillars" and other technical solutions, which have technical effects such as "effectively ensuring the temperature of the hot air blown out, thereby ensuring the defrosting efficiency";

[0004] Since the car defroster has heat dissipation holes for heat dissipation and is equipped with a dust net to reduce dust entry; the heat dissipation holes will improve the heat dissipation efficiency at high temperatures. However, at low temperatures or when not working, some dust will still enter the defroster through the dust net. The accumulation of dust may affect the defroster's heating elements, such as resistance wires, heating plates, etc., resulting in reduced heating efficiency, which in turn affects the defrosting effect.
