Technical Field

[0001] The utility model belongs to the technical field of air-conditioning equipment, and in particular relates to a fresh air air-conditioning. Background Art

[0002] With the development of society and the continuous improvement of people's living standards, air conditioners have become widely popular. In the actual use of air conditioners, when users close the doors and windows to use the air conditioner, people stay indoors for a long time, and the indoor circulating air will become worse and worse; therefore, some fresh air air conditioners have appeared on the market.

[0003] Most of the fresh air air conditioners on the market use separate inlet and outlet air ducts. The fresh air duct and the air conditioning duct are independent of each other, and the air duct is not fully utilized. In addition, motors and fans are also required on the pipes inside the fresh air duct, which increases product costs. Utility Model Content

[0004] In order to overcome the technical problems of the existing fresh air air conditioner that the fresh air duct and the air conditioning duct are independent of each other and the product cost is high, the utility model provides a fresh air air conditioner.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The fresh air air conditioner comprises an air inlet, an air outlet, an evaporator and a fan. The fan is located between the air inlet and the air outlet. The evaporator is located between the air inlet and the fan. An air duct is formed between the air inlet and the air outlet. The fresh air air conditioner is also provided with a fresh air inlet pipe. The outlet end of the fresh air inlet pipe forms or leads to a fresh air inlet inside the fresh air air conditioner. The fresh air air conditioner also comprises a partition. The partition divides the air duct into a main air duct and a fresh air duct. The partition divides the air outlet into a main air outlet and a fresh air outlet. A clearance hole is provided on the partition for the fan to pass through. The evaporator is arranged on the main air duct. On the air duct, the air inlet is connected to the main air duct, and the fresh air inlet pipe is connected to the fresh air duct; ventilation holes are opened on the partition, and the ventilation holes are connected to the main air duct and the fresh air duct. The fresh air air conditioner is also provided with a movable air damper plate and a driving component. The movable air damper plate has a first working position in which the ventilation holes are blocked but the fresh air inlet is not blocked, and also has a second working position in which the fresh air ventilation holes are blocked but the ventilation holes are not blocked. The driving component is used to drive the movable air damper plate to switch between the first working position and the second working position.

[0007] In the present application, a partition is added to divide the air duct into a main air duct and a fresh air duct, and the fan passes through the partition to realize that the main air duct and the fresh air duct share the same fan to reduce costs; specifically, a ventilation hole is also opened on the partition, and an active air damper plate is added to switch between a first working position and a second working position to change the working state of the fresh air air conditioner; specifically, when the active air damper plate is in the first working position, it blocks the ventilation hole, and the fresh air inlet duct is in an open state. At this time, the fresh air air conditioner is in a fresh air on state, the main air duct and the fresh air duct are independent of each other and do not affect each other, and the gas passing through the evaporator is discharged through the main air duct; specifically, when the active air damper plate is in the second working position, it blocks the fresh air inlet duct, and the ventilation hole is in an open state. At this time, the fresh air air conditioner is in a fresh air closed state, and in the fresh air duct, the fan rotates to form a negative pressure, so that part of the gas passing through the evaporator in the main air duct enters the fresh air duct through the ventilation hole and is discharged. Based on the above, the present application realizes the sharing of fans and air outlets in the main air duct and the fresh air duct to reduce costs and improve the utilization rate of the air duct.
