Convection heaters with deflectors

technical field

The utility model relates to a heating device, in particular to a convection electric heater with an air deflector.

Background technique

The working principle of the household convection heater is to use the heating element to heat the cold air, and then emit the heated hot air through air convection, thereby increasing the indoor temperature.

In actual use, users always use it in front of the convection heater, and the air outlets for outputting hot air in the existing convection heaters are all set on the front shell or the upper cover:

When the air outlet is opened on the upper cover, the hot air will be dissipated directly through the air outlet on the upper cover. If the hot air rises directly, the user will not be able to quickly feel the heat emitted by the convection heater. poor;

When the air outlet is directly opened on the front shell, the hot air will first gather on the top of the convection heater and then escape forward from the air outlet, so that the forward momentum of the hot air is not enough when it escapes, and the escape After coming out, it quickly turns to an upward movement, so that the heat emitted by the convection heater cannot be felt a little farther in front of the convection heater, and it will only be warmer when the temperature of the entire environment rises. a feeling of. Moreover, hot air gathers on the top of the convection heater, which can easily cause the upper cover to overheat. Even if it passes the relevant temperature rise test, its temperature is still relatively hot compared to consumers' senses, which will also affect the user experience.
