Description

Technical Field

[0001] This utility model belongs to the field of bathroom heater technology, specifically relating to a cleanable fan-heated bathroom heater. Background Technology

[0002] As a common bathroom heating device, the fan-driven bathroom heater is widely used in homes and public places. Its working principle is that a motor drives a fan to rotate, drawing in cool air from the bathroom through ducts. This air is then heated by a PTC heating module before being delivered into the bathroom. One of the core components is the PTC heating module, which uses the thermosensitive properties of PTC ceramic elements to achieve rapid heating and provide a warm environment for users. However, during long-term use, the PTC heating module is prone to dust accumulation. Dust adhering to the back of the heating element reduces thermal efficiency, increases energy consumption, affects lifespan, and may cause risks such as short circuits and fires. Traditional bathroom heaters typically have the PTC heating module integrated with the main unit, making disassembly difficult and cleaning and maintenance inconvenient. Users need specialized tools to fully open the main unit for cleaning, requiring highly skilled maintenance personnel who cannot operate it themselves, sometimes even requiring return to the factory for maintenance. This not only increases maintenance costs but also reduces the user experience.

[0003] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content
