Technical Field
The invention relates to the technical field of fresh air conditioners, in particular to an indoor unit of a fresh air cabinet type air conditioner.
Background
The air conditioner is a household appliance which is widely applied, generally has heating and refrigerating functions, adjusts the temperature of indoor air when the ambient temperature is too low or too high, provides a proper indoor environment for users, and effectively improves the life quality of the users.
However, since the conventional air conditioner only circularly heats or cools indoor air during heating or cooling, and a user simultaneously closes a door of a living room to maintain the indoor temperature, the indoor air quality is gradually deteriorated over a long period of time, thereby causing adverse effects on the physical health of the user. Particularly, in recent years, the air pollution is increasingly serious, and people are reluctant to open windows for ventilation particularly in winter heating seasons, so that the indoor air quality is increasingly poor, the oxygen content is increasingly low, and the physical health is affected.
