Multi-functional heater with good dustproof effect

Abstract

The invention discloses a multi-functional heater with a good dustproof effect. The multi-functional heater comprises a fixed frame, wherein the fixed frame comprises four vertical fixed tubes; a compression spring is arranged at each of top ends of the four fixed tubes; a box body is fixed to the top end of the fixed frame through bolts; the box body adopts a cuboid structure with a cavity therein, and a circular hole is formed in a middle portion of the upper surface of the box body; annular grooves are formed in the inner wall of the periphery of the circular hole; first louver fans are rotationally connected with the interiors of the annular grooves; a support tube is fixed to the inner wall of the bottom of the box body through bolts; a fixed plate is welded to the top end of the support tube; the top end of the fixed plate is rotationally connected with an axis rotating table; and a support frame is welded to the inner wall of the bottom of the box body. When the heater is not needed, a radiation outlet is closed by rotating the louver fans, so that dust is prevented from dropping onto the surface of a heat conduction tube; and along with the opening and closing of the two louver fans, radiant heat can be dissipated to a wider space.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a multifunctional heater with good dustproof effect. Background technique [0002] There are many kinds of heaters. The most common electric heater is heating equipment that uses electricity as energy for heating and heating. In particular, the heating tube heater is the cheapest and most common. However, this type of heater only has a layer of protective net outside the heating tube. Dust is easy to accumulate on the heating pipe during use, and it cannot be cleaned, and most heaters will be damp and short-circuited when used in a space with high humidity, or the effect will not be obvious due to high humidity during use. Moreover, the warm air blown out is often accompanied by an unpleasant smell, which brings discomfort to the human body in a small space. More heaters or air conditioners are not effective due to insufficient power in a large space, and do not bri...

[0002] There are many kinds of heaters. The most common electric heater is a heating device that uses electricity as energy for heating and heating. In particular, the heating tube heater is the cheapest and most common. However, this type of heater only has a layer of protective net outside the heating tube. Dust is easy to accumulate on the heating pipe during use, and it cannot be cleaned, and most heaters will be damp and short-circuited when used in a space with high humidity, or the effect will not be obvious due to high humidity during use

Moreover, the warm air blown out is often accompanied by an unpleasant smell, which brings discomfort to the human body in a small space.

More heaters or air conditioners in a large space are not effective due to insufficient power, and do not bring people a sense of comfort, especially when workers in the factory are working, because the weather is too cold, resulting in a decline in production efficiency
