Description
Technical field
It the utility model is related to the technical field of domestic-heating system or space-heating system.
Background technology
As the improvement of people's living standards, electric heater as winter family's auxiliary warming apparatus increasingly by people's
Like.Common electric heater is broadly divided into two kinds of light-radiation-type and convection type on the market at present, and convection heater is due to safety
Property good, the advantages that work is quiet, and indoor heating is moist, more favored by customer.Existing convection heater mainly includes
Casing and the heater element installed in casing internal, the upper/lower terminal of the casing are respectively equipped with air port, and heater element is heating
During the air of casing internal is heated, raise the temperature of casing internal, using air at elevated temperatures on
The principle risen, to form the flow effect of air inlet below casing, top exhaust, and then the high temperature air of casing is discharged, reached
The effect of heating.But convection heater fully relies on cross-ventilated effect to realize the flowing of air, heat transmission is slow,
The efficiency that heats up is low.
More commonly used warmer also has fan-type warmer in the prior art, i.e., is provided with heater element simultaneously in casing
And fan, fan and heater element synchronous operation, hot-air is discharged in real time, to improve the efficiency of transmission of heat, accelerated indoor
Heating.But fan-type warmer the problem of existing is that noise is big, it is not suitable for the length of one's sleep in the evening.Do not have also in the market
There is one kind to be rapidly heated, be applied to the warmer of quiet environment again.
Utility model content
