Description

Technical Field

[0001] The utility model relates to the technical field of bathroom heaters, in particular to an air inlet structure of a bathroom heater. Background Art

[0002] Bathroom heater is a commonly used heating equipment in bathroom. It has functions such as heating and ventilation. Some existing bathroom heaters adopt a dual-fan structure. The two fans correspond to the heating function and the ventilation function respectively. The heating and ventilation functions of the dual-motor bathroom heater can work at the same time.

[0003] However, when the heating function and the ventilation function are turned on at the same time, since both heating and ventilation require air intake, the two air ducts will compete with each other for air volume, disrupting the airflow at the air inlet and the two air ducts, reducing the air intake of the two air ducts, resulting in a decrease in heating power and thermal performance, as well as a decrease in ventilation performance. Therefore, both functions will be weakened, the performance cannot be balanced, and the experience is also poor. Utility Model Content
