Problems solved by technology
[0004] The purpose of the present invention is to solve the technical problem that the existing axial flow cooling and heating circulation fan has a large amount of heating air and is mixed with unheated cold air, resulting in an unsatisfactory somatosensory effect. Therefore, the present invention provides an air duct The variable cooling and heating circulation fan can not only realize the adjustment of the cold air volume, but also improve the heating effect

The invention discloses a cooling and heating circulation fan with a variable air duct. The cooling and heating circulation fan is characterized in that a section of radial air inlet channel is arranged on a rear mesh enclosure located between fan blades and a heating assembly, a section of closed annular air channel is formed at the front end of the rear mesh enclosure and connected with the radial air inlet channel, a plurality of air blocking pieces are further arranged at the radial air inlet channel, a rotating shaft and a limiting shaft are arranged at the two ends of each air blocking piece, a plurality of front supporting plates and rear supporting plates with positioning holes and limiting long holes are arranged at the two ends of the radial air inlet channel, the rotating shafts and the limiting shafts at the two ends of the air blocking pieces are arranged in the positioning holes and limiting long holes corresponding to the front supporting plates and the rear supporting plates respectively, the rotating shafts of the air blocking pieces take the centers of the positioning holes as the axes, and the limiting shafts rotate along the limiting long holes; and the width size of the air blocking pieces is larger than or equal to the width size of a radial air inlet gap formed between every two adjacent air blocking pieces. According to the cooling and heating circulation fan, cold air and warm air are switched for use, the phenomenon that cold air is mixed during warm air can be completely avoided, and the body feeling of a user is effectively improved.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a cooling and heating circulation fan with a variable air duct. Background technique [0002] Heaters or fans are essential appliances in modern households. At present, there are either a single heater or a single fan on the market, but there are very few products that can truly combine the functions of heater heating and fan blowing. It is a cooling and heating type circulation fan. The cooling and heating circulation fan can be used not only as a heater, but also as a fan. Due to the fixed product structure of the cooling and heating circulation fan, the axial flow fan blades enter the air synchronously in both radial and axial directions, and the air intake volume is large. When warm air is needed, the hot air blown out is also mixed with cold air, especially around the entire front net, and the body feeling is not very ideal. [0003] For example, the Chinese pate...
