When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

The fresh air cover comprises oppositely and buckled first and second side fresh air covers 4i and 4j, and an upper fresh air cover 4k arranged above the first and second side fresh air covers 4i and 4j.

[0118] More specifically, as shown in Figure 9 the fresh air motor 4b is merged and surrounded by the first and second partitions 4c and 4d. The fresh air centrifugal fan blade 4g is installed on the motor shaft on one side of the first partition 4c. The fresh air volute 4e is installed on the side of the fresh air centrifugal fan blade 4g close to the first partition 4c. The waste gas volute 4f is first installed on one side of the second partition 4d, and then the waste gas centrifugal fan blade 4h is installed on the motor shaft on the same side.

[0119] The first and second side fresh air covers 4i and 4j of the fresh air module 4 are buckled to each other to surround the above-mentioned components. The upper fresh air cover 4k is installed on the top side. The total heat exchanger 4a is installed on the top side of the first and second partitions 4c and 4d and the bottom side of the upper fresh air cover 4k. A fresh air filter screen 48 is arranged on the inner side of the fresh air inlet 41 to filter the fresh air introduced from the outside.

[0120] It should be noted that the above-mentioned air duct centrifugal fan blade 200 can be placed horizontally. For an overall air conditioner with a short outdoor side, such as a wall-through machine, the air duct centrifugal fan blade 200 can also be arranged parallel to the front partition 1. The direction of the air duct centrifugal fan blade 200 and the air duct volute 2 can be adjusted as needed.

[0121] It should be noted that the inlet and outlet air faces of the total heat exchanger 4a are not horizontal or vertical, and the installation angle can be adjusted as needed. The position of the total heat exchanger 4a can be on the upper side, lower side, outer side, inner side, left side, and right side of the two fan blades (fresh air centrifugal fan blade 4g and exhaust air centrifugal fan blade 4h).

[0122] It should be noted that the fresh air module 4 can be installed in any part of the duct volute 2 and the front partition 1 that has space, completely or partially on the indoor side, and the installation direction of the fresh air module 4 can also be adjusted as needed.

[0123] It should be noted that the fresh air exhaust port 42 downstream can be directly connected to a heat exchanger, so that the fresh air passes through the total heat exchange and then passes through the heat exchanger again, to achieve a superimposed heat exchange effect. The exhaust air inlet port 43 can also be directly connected to the air inlet panel of the air conditioner through a pipeline or other channel.

[0124] It should be noted that the fresh air control logic of the window type air conditioner is as follows: first, when the user turns on or sets the fresh air function, the drive motor that drives the blades (fresh air guide blade and exhaust air guide blade) is turned on, so that the blades are rotated to a reasonable angle, i.e. the indoor exhaust air is guided to the upstream of the outdoor fan and is sucked away by the outdoor fan, and the fresh air enters through the fresh air inlet port 41 on the other side. Then turn on the fresh air motor and perform fresh air exchange. When the fresh air function is turned off by the user or the timer, first turn off the fresh air motor, and then start the blade drive motor to close the fresh air inlet port and the exhaust air outlet port.
