Embodiment 2

[0023] In this embodiment, the heater described in Embodiment 1 is adopted, the power of the electrothermal film is 500W, and the power of the fan is 200W. The test is carried out in a room of 10 square meters. The outdoor temperature is 0 degrees Celsius. The local temperature is 18 degrees Celsius, the temperature at the place 1m above the ground is 15 degrees Celsius, and the temperature at the place 10cm above the ground is 8 degrees Celsius; after working for 1 hour, the temperature at the place 2m above the ground in the room is 22 degrees Celsius, 1m above the ground. The temperature in the room is 20 degrees Celsius, and the temperature at the place 10cm above the ground is 14 degrees Celsius; after working for 1.5 hours, the temperature in the room is 24 degrees Celsius at the height of 2m above the ground, and 23 degrees Celsius at the place 1m above the ground, 10cm above the ground. The highest temperature is 20 degrees Celsius.

Embodiment 3

[0025] This example is a comparative example of Example 2. A 220V, 500W flat-blowing heater is used to test in a room of 10 square meters. The outdoor temperature is 0 degrees Celsius. After working for 1.5 hours, in the front area of ​​the heater, The temperature is 20-28 degrees Celsius, and the temperature in the area behind the warm air is 8-18 degrees Celsius. If people leave from the warm air area, the sudden change in temperature will easily make people feel uncomfortable.

Abstract

The invention discloses a rotary electrothermal film heating fan. The rotary electrothermal film heating fan comprises an electrothermal film, and further comprises a cylindrical upper shell and a circular-truncated-cone-shaped lower shell. An opening in one end of the upper shell is connected with an opening in the smaller end of the lower shell. The electrothermal film is arranged in the upper shell and matched with the inner surface of the upper shell. A fan is arranged in the lower shell. When the fan works, airflows moves from the bottom to top. Through holes are further formed in the lower shell. The rotary electrothermal film heating fan has the advantages that the electrothermal film is adopted for supplying heat, hot air is blown from bottom to top, the safety is high, and the body feeling is comfortable; the surrounding air can be purified while heat supply operation is conducted; and the fan and the electrothermal film are controlled separatedly, and resources are saved.

Description

technical field [0001] The invention relates to a heater, in particular to a rotary electric heating film heating fan. Background technique [0002] As the name suggests, the heater is a device that emits warm air. Generally speaking, the maximum temperature is about 70-300°C. It includes three parts: heating, blowing, and temperature and blowing control and protection. It is suitable for forced circulation air heating of various types of workshops and large buildings. It can make the room temperature reach the required temperature in a short time. It is an ideal heating equipment for modern factories, restaurants, theaters and other tall buildings. The existing heater has continuously adjustable temperature; double automatic overheating protection, manual restart device; unique warm air start and automatic cooling stop device. The fan is automatically activated after the electric heating tube is preheated to a certain temperature to ensure that the warm air is available im...
