Abstract

The invention relates to the technical field of air conditioning, in particular to a nozzle structure, a fresh air exchange device and an air conditioner. The nozzle structure comprises an outer cylinder, an inner cylinder and an air guide channel; the outer cylinder sleeves the inner cylinder; since the outer cylinder sleeves the inner cylinder and the back end of the inner cylinder is sealed, high-speed air flow can pass through the space between the outer cylinder and the inner cylinder, and then blows out forwards from an outlet in the front end of the outer cylinder to form columnar jet flow, and the columnar jet flow can be entrained by active turbulent flow on the boundary and then is mixed with air flow in the inner cylinder; and since the air guide channel runs through the space between the outer cylinder and the inner cylinder, indoor air enters the inner cylinder from the air guide channel to be mixed with high-speed air flow blown out from the outlet in the front end of the outer cylinder to form jet flow, through the process, high-speed air flow generated by a driving air source is introduced, and meanwhile, through entrainment and mixing effects of the turbulent flow on the boundary of the high-speed air flow, indoor air flows and circulates in an air flow induction manner and further the problem of high possibility of unwell symptoms caused by the fact that a user stays in an air conditioning room for a long time can be solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a nozzle structure, a fresh air replacement device and an air conditioner. Background technique [0002] At present, air conditioners have been widely popularized and become one of household appliances commonly used in people's daily home life. However, if a person stays in an air-conditioned room for a long time, he is prone to headache, dizziness, palpitation, weakness and other uncomfortable symptoms. These symptoms are mainly caused by the closed air-conditioned room and the lack of indoor air circulation, which makes the indoor air negative ions scarce. Therefore, how to introduce fresh air and promote air flow in air-conditioned rooms is an effective way to overcome the above symptoms. [0003] Therefore, in view of the above deficiencies, it is necessary to provide a nozzle structure, a fresh air replacement device and an air conditioner. Contents of the invent...
