Abstract

An air conditioning device is provided. The device has a fresh air component and a control valve assembly. The fresh air component has a housing assembly and an air treatment assembly. The housing assembly has a ventilation cavity, a fresh air cavity and an exhaust cavity. The air treatment assembly is disposed in the exhaust cavity. The control valve assembly has a first valve assembly and a second valve assembly, which are independent of each other. An outlet of the ventilation cavity is in communication with an indoor space through the exhaust cavity and an air outlet when the first valve assembly is in an open state. The outlet of the ventilation cavity is in communication with the fresh air cavity when the second valve assembly is in an open state.

First claim

What is claimed is:

1 . An air conditioning device comprising:
an air outlet adapted to be in communication with an indoor space; a return air inlet adapted to be in communication with the indoor space; a fresh air inlet adapted to be in communication with an outdoor space; a fresh air cavity in communication with the fresh air inlet; a ventilation cavity comprising:
an upper cavity; and
a rear cavity;
an exhaust cavity in communication with the air outlet and the upper cavity; a heat exchanger or heater disposed within the exhaust cavity; a first valve assembly configured to control communication between the upper cavity and the air outlet; a second valve assembly configured to control communication between the upper cavity and the fresh air cavity; a third valve assembly configured to control communication between the fresh air cavity and the rear cavity; and a fourth valve assembly configured to control communication between the return air inlet and the rear cavity.

2 . The air conditioning device according to claim 1 , wherein:
the fresh air cavity is located at a rear side of the ventilation cavity; and the third valve assembly is disposed between a front of the fresh air cavity and a rear of the ventilation cavity and comprises a plurality of first vertical baffles sequentially arranged in a left-right direction.

3 . The air conditioning device according to claim 1 , wherein the first valve assembly is arranged downstream of the heat exchanger or heater.

4 . The air conditioning device according to claim 3 , wherein the first valve assembly is disposed at the air outlet and is configured to control opening or closing of the air outlet.

5 . The air conditioning device according to claim 3 , wherein the first valve assembly comprises a plurality of second vertical baffles sequentially arranged in a transverse direction of the air outlet.

6 . The air conditioning device according to claim 1 , wherein the first valve assembly is arranged upstream of the heat exchanger or heater.

7 . The air conditioning device according to claim 6 , wherein the first valve assembly is located below the heat exchanger or heater and comprises a plurality of first transverse baffles sequentially arranged in a front-rear direction.

8 . The air conditioning device according to claim 1 , wherein:
the fresh air cavity is located at a rear side of the ventilation cavity; the exhaust cavity is located above the ventilation cavity; a top of the upper cavity being in communication with the exhaust cavity through a first outlet, a rear of the upper cavity being in communication with an upper part of the fresh air cavity through a second outlet; and the second valve assembly is disposed at the second outlet and is configured to control opening or closing of the second outlet.

9 . The air conditioning device according to claim 8 , wherein the second valve assembly comprises a second transverse baffle.

10 . The air conditioning device according to claim 8 , wherein a centrifugal fan is disposed in the ventilation cavity.

11 . The air conditioning device according to claim 10 ,
wherein the centrifugal fan is disposed between the rear cavity and the upper cavity.

12 . The air conditioning device according to claim 1 , wherein the fourth valve assembly is disposed at the return air inlet and is configured to control opening or closing of the return air inlet.

13 . The air conditioning device according to claim 1 , further comprising a fifth valve assembly configured to control communication between the fresh air inlet and the fresh air cavity.

14 . The air conditioning device according to claim 1 ,
further comprising at least one treatment module adapted to be inserted into the exhaust cavity.

15 . The air conditioning device according to claim 1 , further comprising a housing assembly, wherein the housing assembly comprises an upper housing assembly and a lower housing assembly, wherein:
the upper housing assembly is disposed above the lower housing assembly and defines the exhaust cavity; the lower housing assembly defines the ventilation cavity and the fresh air cavity; and the upper housing assembly comprises an upper housing and a lower housing, the upper housing being provided above the lower housing, the heat exchanger or heater being mounted in the lower housing, and the air outlet being formed on a front part of each of a left side wall and a right side wall of the upper housing.

16 . The air conditioning device according to claim 1 , further comprising a fresh air component comprising the fresh air cavity, the ventilation cavity, the exhaust cavity, the heat exchanger or heater, the second valve assembly and the third valve assembly.

17 . The air conditioning device according to claim 16 , further comprising a casing component comprising the air outlet and the return air inlet.
