The air conditioning system is used as indoor temperature adjusting equipment, occupies an increasingly important position in the life of people, and brings healthy air for the life of people. The air conditioning systems are various in types and brands at present, so that consumers can select a large number of air conditioning systems, how to obtain the favor of the consumers is achieved, the product competitiveness is improved, and the problem that air conditioning system manufacturers attach more and more importance is solved.

At present, an air conditioning system comprises an air conditioning indoor unit, and a fresh air device is arranged in part of the air conditioning indoor unit to replace indoor air so as to improve indoor air quality.

However, in the related art, the fresh air outlet is opened or closed through the sliding door, so that when the fresh air is not used, the fresh air outlet can be closed, and the effect of protecting a fresh air component is achieved. However, the arrangement of the sliding door results in a complex structure and high cost of the indoor unit of the air conditioner.

Accordingly, it is desirable to provide a fresh air device, an indoor air conditioner, and an air conditioning system.

In order to better understand the fresh air device of the present disclosure, the air conditioner indoor unit using the fresh air device is explained.

As shown in fig. 1 to 4, in the embodiment of the present disclosure, an air conditioning indoor unit 10 includes a main body 11 and a fresh air device 12, where the fresh air device 12 is disposed on the main body 11. The fresh air device 12 includes a housing assembly 100, an adapter tube 200, and a valve assembly 300; the housing assembly 100 is provided with an air inlet 111; one end of the adapter tube 200 is communicated with the air inlet 111, and the other end is used for being connected with a fresh air pipe; the valve assembly 300 includes a valve 310 and a driver 320, wherein the valve 310 is disposed in the adapter tube 200 and moves under the action of the driver 320 to open or close the adapter tube 200.

When the indoor unit 10 of the air conditioner is used, at least a part of the fresh air duct 700 is disposed outdoors (see fig. 6), and the adapter tube 200 is communicated with the fresh air duct 700 to form a fresh air intake channel (see fig. 6), so that outdoor air can be introduced into the fresh air device 12 through the fresh air intake channel. When the fresh air function is used, the driver 320 acts to drive the valve 310 to move, so as to open the adapter tube 200 (as shown in fig. 4), so that the indoor unit 10 of the air conditioner is communicated with the outdoor air through the fresh air inlet channel, and fresh air flow is provided for indoor users. When the fresh air function is not used, the driver 320 acts in the reverse direction to drive the valve 310 to move, so as to close the adapter tube 200 (as shown in fig. 3), and further close the fresh air inlet channel, so that the indoor unit 10 of the air conditioner is not communicated with outdoor air, condensation in the fresh air inlet channel is avoided, and the service life of the filter assembly 600 is prolonged. So, this machine 10 in air conditioning can close new trend inlet channel when the new trend function is not used for machine 10 in air conditioning does not communicate with outdoor air, avoids producing the condensation phenomenon in new trend inlet channel, is favorable to improving the life of filtering component 600, guarantees the clean degree of new trend.

It can be understood that when the fresh air function is not used, the indoor unit 10 of the air conditioner is not communicated with the outdoor air, and outdoor dust can be prevented from entering the casing assembly 100 through the fresh air inlet channel, so that the filtering effect of the filtering assembly 600 is maintained, the maintenance period of the filtering assembly 600 is prolonged, and the maintenance cost of the filtering assembly 600 is reduced. In addition, when the indoor unit 10 of the air conditioner adjusts the temperature indoors, the temperature adjusting gas can be prevented from escaping outdoors through the fresh air inlet channel from the indoor space, so that the electric energy can be saved, a better air conditioner product can be provided for users, the favor of consumers can be obtained, and the product competitiveness can be improved.

Furthermore, the valve 310 is disposed in the adapter tube 200 of the casing assembly 100, so that the valve assembly 300 can be easily integrated into the indoor unit 10 of the air conditioner for easy control.

It should be noted that the "body 11" includes a casing of the indoor unit 10, and is used for accommodating other air conditioning components (including the fresh air power assembly 500), such as a control panel, a heat exchanger, a return air power set, and fan blades.

The driver 320 may be configured according to a desired movement manner of the valve 310, and includes a reciprocating device, a swinging driving device, a rotating driving device, and the like, and the driving power thereof may be manual or electric, and the like, which is not limited herein.

If the manual operation is adopted, the user can be reminded to manually drive the driver 320 in time to drive the valve 310 to move by setting a sound reminding mode or a light reminding mode, so that the adapter tube 200 can be opened or closed.

In some embodiments, the non-flexible material that is not deformable under an external force is used, and the adapter tube 200 is formed to have a bent portion, one end of the adapter tube 200 is communicated with the air inlet 111, and the other end is used for being connected with the fresh air duct 700.

As shown in fig. 3 and 4, in some embodiments, a mounting portion 250 is disposed on an outer side of the adapter tube 200, the driver 320 is fixed to the housing assembly 100 through the mounting portion 250, and the rotating body 312 is in sleeve-connection and transmission-fit with the power output end 321. Therefore, the power output end 321 is in sleeve fit with the rotating body 312 through the through hole 240, and can drive the rotating body 312 to rotate, and further can drive the valve 310 to rotate. At this time, the driver 320 only needs to be fixed to the mounting portion 250.

The driver 320 is secured to the mounting portion 250 by any means including, but not limited to, threading, snapping, bonding, welding, etc.
