Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a double-duct ceiling heater. Background Art

[0002] A ceiling heater is a heating device installed on the top of a room that blows air directly downward to heat the room. Unlike traditional radiators, it can heat the room in a shorter time. A ceiling heater uses energy such as electricity or gas to heat the air, and then sprays the heated air out through a built-in fan to quickly heat the air in the room.

[0003] However, when the existing dual-duct ceiling heater is in use, the air duct on the heater is always in an open state, and foreign objects floating from the outside can easily enter the interior of the heater. When the heater is in heating operation, the temperature inside the heater rises, and the foreign objects melt inside the heater and adhere to the heating components inside the heater, which has a certain impact on the service life of the heater. At the same time, motors are installed on the two air ducts of the heater to drive the fan blades to rotate, which increases the cost of use. Therefore, a dual-duct ceiling heater is provided. Utility Model Content

[0007] When the indoor heating is finished, the motor B in the connecting frame converts the received electrical energy into mechanical energy, and the motor B drives the driving gear to rotate, and then the driving gear drives the tooth plate A to move, and the tooth plate A blocks the air duct A on the connecting frame. At the same time, the driving gear drives the tooth plate B to move, and the tooth plate B blocks the air duct B on the connecting frame B, thereby preventing foreign objects from entering the fixed frame through the air duct A and the air duct B, and preventing the heating components in the fixed frame from being damaged.

The fan blades A outside the driving rod A rotate to accelerate the air flow speed on the surface of the heater. At the same time, the driving gear B drives the driving rod B on the driven gear B to rotate. Then the fan blades B outside the driving rod B rotate to accelerate the air flow speed on the surface of the heater. Then, the hot air is transmitted to the room through the air ducts A and B, thereby improving the indoor heating efficiency. When a single motor is used, the warm air is transmitted from the air ducts A and B respectively, thereby reducing the processing cost.
