Abstract

An electric heater includes primarily an S-shaped air channel which is provided in a body, at least one heating unit which is provided in the air channel, and at least one heat energy conversion unit which is close to an inner wall of the air channel and close to the heating unit. An interior of the heat energy conversion unit is defined with a passage. Hot air can be directed rapidly by a principle that hot air ascends, through the S-shaped air channel. Heat energy produced by the heating unit is absorbed by the heat energy conversion unit and is then carried away by an air power of the passage, so as to achieve effects of heat accumulation and dissipation.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An electric heater comprising a body, an interior of which is defined with an air channel, the air channel being defined with an air inlet at a bottom of the body and an air outlet at a top of the body; at least one heating unit which is provided in the air channel; and at least one heat energy conversion unit which is close to an inner wall of the air channel and close to the heating unit. 
     
     
         2 . The electric heater according to  claim 1 , wherein the air inlet of the air channel is provided with an air guiding element which guides air into the air channel. 
     
     
         3 . The electric heater according to  claim 1 , wherein the heating unit is a quartz heating tube. 
     
     
         4 . The electric heater according to  claim 1 , wherein the heat energy conversion unit is made by a metallic material and an interior of the heat energy conversion unit is defined with a passage allowing air to pass through. 
     
     
         5 . The electric heater according to  claim 1 , wherein a bottom of the body is further provided with rollers for moving the body. 
     
     
         6 . The electric heater according to  claim 1 , wherein the air channel is in an S-shaped configuration. 
     
     
         7 . The electric heater according to  claim 1 , wherein the air inlet is further provided with an air guiding plate.
