The fresh air inner shell 30 is arranged in the non-heat exchange chamber 12, the outlet 312 of the induced air channel 31 is communicated with the heat exchange chamber 11, and the inlet 321 of the exhaust channel 32 is communicated with the non-heat exchange chamber 12. Therefore, the fresh air flow introduced by the air inducing channel 31 is discharged into the heat exchange cavity 11 to be mixed with the heat exchange air flow, and the temperature is closer to that of the heat exchange air flow. The phenomenon that fresh air with too low temperature in winter or fresh air with too high temperature in summer enters the indoor environment to have adverse effect on the indoor environment temperature and cause discomfort to a human body is avoided.
In some embodiments of the present invention, as shown in fig. 2, a heat exchanger 21 and a fan 22 are disposed in the heat exchange chamber 11, and an outlet 312 of the induced air passage 31 is communicated to an upstream side of the heat exchanger 21. Therefore, the fresh air flow exchanges heat with the heat exchanger 21 firstly and then enters the indoor environment, and the situation that fresh air with too low temperature in winter or fresh air with too high temperature in summer enters the indoor environment is avoided.
In some embodiments of the present invention, as shown in fig. 2, the casing 10 further has a fresh air inlet 311 connected to the inlet end of the induced air channel 31, and the fresh air inlet 311 is connected to the fresh air inlet pipe 81 connected to the outdoor environment. The casing 10 is further provided with a fresh air outlet 322 connected to the outlet end of the air exhaust channel 32, and the fresh air outlet 322 is used for being connected to a fresh air exhaust pipe 82 connected to the outdoor environment. In the embodiment, the fresh air inlet pipe 81 and the fresh air exhaust pipe 82 are designed to be detachably mounted on the independent part of the shell 10, so that the air conditioner can be more convenient to practice, manufacture and transport.
Further, as shown in fig. 2, the first damper 41 may be disposed at the fresh air inlet 311, and the second damper 42 may be disposed at the fresh air outlet 322.
Further, the first damper 41 may be configured to rotatably open and close the induced air passage 31, and the second damper 42 may be configured to rotatably open and close the discharge air passage 32. Specifically, as shown in fig. 2, the first damper 41 may be made in a plate shape with its axis extending vertically, which is driven by a stepping motor 51. The second damper 42 may be made in the form of a plate whose axis extends vertically, and which is driven by a stepping motor 52.
Fig. 3 is a partial schematic structural view of the inside of an air conditioner according to another embodiment of the present invention, in some embodiments, the induced air fan 91 is a centrifugal fan or an axial flow fan, and the exhaust air fan 92 is a centrifugal fan or an axial flow fan.
For example, as shown in fig. 2, both the induced air fan 91 and the exhaust air fan 92 may be centrifugal fans. Alternatively, as shown in fig. 3, the induced air fan 91 is a centrifugal fan, and the exhaust air fan 92 is an axial flow fan.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
