Electric heater

Abstract

The invention relates to the technical field of electric heaters, and particularly discloses an electric heater, which comprises a main body and a protruding part. A vertical air channel is arranged in the main body; the protruding part is arranged in a middle area of the top of the main body; and an air outlet is formed in the protruding part and communicates with the vertical air channel. In the vertical direction, the height of the protruding part is h1, and the height of the main body is h2; and aiming at the situation that with the arrangement, the two ends of a heating body do not emit heat due to the process, the temperature distribution of the whole heating body is uneven, the temperature of the two ends is low, the temperature of the middle area is high, and the temperature of the air outlet and the temperature of the middle area of the main body are relatively high, the protruding part is arranged in the middle area, so that the chimney effect of the middle area is strengthened, heat convection is strengthened, the air flowing rate of the middle area is increased, the air temperature is reduced, the temperature of a local high-temperature area is reduced, the temperature difference between the two ends and the middle area is further reduced, and meanwhile, safe and stable operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric heaters, in particular to an electric heater. Background technique [0002] With the improvement of people's living standards, many household appliances have entered people's daily life, and the baseboard heater is one of them. At present, the baseboard heaters on the market are mainly used for heating the whole house, and have the advantages of small footprint, low noise, reliable operation and beautiful appearance. [0003] At present, when the baseboard heater is in use, the main body, air outlet grille and other components are prone to local temperature exceeding the standard, which affects the safety and service life of the heater. The structure of baseboard heaters on the market basically adopts the form of bottom in and top out. The inlet and outlet grilles are generally straight, and there are also inclined types. Some baseboard heaters can adjust the inlet and outlet angles. The ventil...
