[0035] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0036] The air conditioner provided in this embodiment is intended to at least to some extent solve the technical problem that when there is a large temperature difference between indoor and outdoor, the fresh air module directly draws outdoor air into the room, resulting in a decrease in comfort and affecting the user experience.

[0037] Figure 1 is a schematic structural diagram of an air conditioner according to some embodiments; Figure 2 for Figure 1 Schematic diagram of fresh air intake for the air conditioner; Figure 4 for Figure 1 Schematic diagram of exhaust air of air conditioner. Figure 1 、 Figure 2 and Figure 4 The air conditioner of the embodiment of the present application includes: a first shell 10, a fresh air module 20, a heat exchanger 30 and an air duct 40. The heat exchanger 30 is arranged in the first shell 10, and the shell is provided with a first air outlet 101. The fresh air module 20 includes a second shell 201 connected to the first shell 10 and a fan assembly 202 arranged in the second shell 201. The second shell 201 is provided with a first air inlet 203, an openable and closable air outlet 204 and an openable and closable second air outlet 205. The second air outlet 205 is located between the heat exchanger 30 and the first air outlet 101 and is connected to the first shell 10. The air duct 40 is arranged in the second shell 201 and is connected to the first air inlet 203. The air duct 40 is provided with an openable and closable second air inlet 401 and an openable and closable third air outlet 402. Among them, when the exhaust outlet 204 and the third air outlet 402 are in a closed state, the second air outlet 205 and the second air inlet 401 are in an open state, the outdoor fresh air enters the room through the first air inlet 203, the air duct 40, the second air inlet 401, the fan assembly 202, the second air outlet 205 and the first air outlet 101 in sequence. When the second air outlet 205 and the second air inlet 401 are in a closed state and the exhaust outlet 204 and the third air outlet 402 are in an open state, the indoor polluted air is discharged through the exhaust outlet 204, the fan assembly 202, the third air outlet 402, the air duct 40 and the first air inlet 203 in sequence.

[0038] The heat exchanger 30 may be an evaporator.

[0039] Since the first shell 10 is provided with a heat exchanger 30 and the shell is provided with a first air outlet 101, the heat exchanger 30 can be supported by the first shell 10, and the air after heat exchange by the heat exchanger 30 can enter the room through the first air outlet 101. Since the fresh air module 20 includes a second shell 201 connected to the first shell 10 and a fan assembly 202 provided in the second shell 201, the second shell 201 is provided with a first air inlet 203, an openable and closable air outlet 204 and an openable and closable second air outlet 205. The second air outlet 205 is located between the heat exchanger 30 and the first air outlet 101 and is connected to the first shell 10. The air duct 40 is located in the second shell 201 and is connected to the first air inlet 203. The air duct 40 is provided with an openable and closable second air inlet 401 and an openable and closable third air outlet 402. Therefore, when the difference between indoor and outdoor temperatures is large, the exhaust port 204 and the third air outlet 402 can be closed, and the second air outlet 205 and the second air inlet 401 can be opened. The outdoor fresh air passes through the first air inlet 203 in sequence. 03, the air duct 40, the second air inlet 401, the fan assembly 202, the second air outlet 205 and the first air outlet 101 enter the room, the outdoor fresh air and the air after heat exchange with the heat exchanger 30 will be mixed in the first shell 10, and the mixed air enters the room through the first air outlet 101, so as to realize the introduction of fresh air into the room and improve the indoor air quality. At the same time, the temperature difference between the outdoor fresh air and the indoor environment can be reduced, which can improve the comfort level. In addition, condensation can be avoided at the second air outlet 205, which also reduces the The possibility of condensation at the first air outlet 101 improves the user experience. When the indoor air is turbid and needs to be discharged, the second air outlet 205 and the second air inlet 401 are closed, and the exhaust port 204 and the third air outlet 402 are opened. The indoor polluted air is discharged in sequence through the exhaust port 204, the fan assembly 202, the third air outlet 402, the air duct 40 and the first air inlet 203, which can improve the indoor air quality, effectively reduce the concentration of indoor harmful gases, and further improve user comfort.

[0040] Figure 3 for Figure 2 Combined with the top view of Figure 2 and Figure 3 In some embodiments, when the temperature difference between indoor and outdoor is small, the outdoor fresh air directly entering the room will not cause a significant decrease in comfort. There is no need to start the heat exchanger 30. The exhaust port 204 and the third air outlet 402 can be closed, and the second air outlet 205 and the second air inlet 4012 can be opened. The outdoor fresh air enters the room through the first air inlet 203, the air duct 40, the second air inlet 401, the fan assembly 202, the second air outlet 205 and the first air outlet 101 in sequence. The outdoor fresh air can be directly input into the room. At this time, since the heat exchanger 30 is not started, the power consumption can be reduced, energy conservation and emission reduction can be achieved, and the user's comfort can be improved.

[0041] In some embodiments, to achieve fresh air intake and exhaust of waste air by the fresh air module 30, the fan assembly 202 has an air inlet end and an air outlet end. When the second air inlet 401 is in an open state, the second air inlet 401 is connected to the air inlet end, and when the third air outlet 402 is in an open state, the third air outlet 402 is connected to the air outlet end.

[0042] In some embodiments, when fresh air is to be introduced, the fan assembly 202 is started, the exhaust port 204 and the third air outlet 402 are closed, and the second air outlet 205 and the second air inlet 401 are opened. The fresh air from the outside enters the fan assembly 202 in sequence through the first air inlet 203, the air duct 40, the second air inlet 401, and the air inlet end, and then enters the room through the air outlet end, the second air outlet 205, and the first air outlet 101, thereby introducing fresh air into the room and improving the indoor air quality. When dirty air is to be discharged, the second air outlet 205 and the second air inlet 401 are closed, and the exhaust port 204 and the third air outlet 402 are opened. The dirty air in the room is discharged in sequence through the exhaust port 204, the air inlet end, the fan assembly 202, the air outlet end, the third air outlet 402, the air duct 40, and the first air inlet 203, thereby improving the indoor air quality and effectively reducing the concentration of harmful gases in the room.

[0043] Combine Figure 2 and Figure 4 In some embodiments, in order to ensure the quality of the air entering the room, the air conditioner further comprises: a filter element 70. The filter element 70 is provided in the second housing 201 and is located between the second air inlet 401 and the air inlet end.

[0044] In some embodiments, when fresh air is to be introduced, outdoor air enters the fan assembly 202 through the first air inlet 203, the air duct 40, the second air inlet 401 and the air inlet end. In the process of the air entering the air inlet end from the second air inlet 401 and the air inlet end, the filter element 70 can effectively filter out dust, pollen, bacteria and other pollutants in the air entering the fan assembly 202, thereby improving the quality of air entering the room and ensuring the comfort of the user. Moreover, it can reduce the impurities in the air entering the interior of the fan assembly 202, especially protecting key components such as the fan in the fan assembly 202, extending its service life, reducing performance degradation or failure caused by dust accumulation, and ensuring the safety of the fan assembly 202.

[0045] Combine Figure 2 and Figure 4In some embodiments, in order to ensure smooth intake of fresh air and exhaust of sewage air, the third air outlet 402 is located between the second air outlet 205 and the second air inlet 401, and the second air inlet 401 is located between the first air inlet 203 and the second air outlet 205. That is to say, when taking in fresh air, it is ensured that outdoor air can enter the second air inlet 401 through the air duct 40 without passing through the third air outlet 402. When exhausting sewage air, the indoor air can enter the air duct 40 through the third air outlet 402 and then be discharged from the first air inlet 203, and will not pass through the second air inlet 401 to reach the fan assembly 202, thereby ensuring smooth ventilation.

[0046] Combine Figure 2 and Figure 4 In some embodiments, to control the opening and closing of the second air inlet 401 and the third air outlet 402, the air conditioner further includes a blocking assembly 50. The blocking assembly 50 is disposed within the air duct 40 and is switchable between a first position and a second position. When the blocking assembly 50 is in the first position, the blocking assembly 50 opens the second air inlet 401 and closes the third air outlet 402. When the blocking assembly 50 is in the second position, the blocking assembly 50 closes the second air inlet 401 and opens the third air outlet 402.

The fresh air outside enters the room through the first air inlet 203, the air duct 40, the second air inlet 401, the fan assembly 202, the second air outlet 205 and the first air outlet 101 in sequence, thereby introducing fresh air into the room and improving the indoor air quality. When the dirty air needs to be discharged, when the blocking component 50 is in the second position, the blocking component 50 closes the second air inlet 401 and opens the third air outlet 402. The second air outlet 205 is in a closed state and the exhaust port 204 is in an open state. The indoor dirty air is discharged through the exhaust port 204, the fan component 202, the third air outlet 402, the air duct 40 and the first air inlet 203 in sequence, which can improve the indoor air quality and effectively reduce the concentration of harmful gases in the room.

[0048] Combine Figure 2 and Figure 4In some embodiments, in order to control the opening and closing of the second air inlet 401 and the third air outlet 402, the blocking component 50 includes: a first blocking member 501 and a second blocking member 502. The first blocking member 501 is rotatably disposed in the air duct 40. The second blocking member 502 is rotatably disposed in the air duct 40. When the blocking component 50 is in the first position, the first blocking member 501 opens the second air inlet 401, and the second blocking member 502 closes the third air outlet 402. When the blocking component 50 is in the second position, the first blocking member 501 closes the second air inlet 401, and the second blocking member 502 opens the third air outlet 402.

[0049] In some embodiments, when fresh air is to be introduced, the fan assembly 202 is started and the blocking assembly 50 is in the first position. At this time, the first blocking member 501 opens the second air inlet 401, the second blocking member 502 closes the third air outlet 402, the exhaust port 204 is in a closed state, and the second air outlet 205 is in an open state. The fresh air outside enters the room through the first air inlet 203, the air duct 40, the second air inlet 401, the fan assembly 202, the second air outlet 205 and the first air outlet 101 in sequence, thereby introducing fresh air into the room and improving the indoor air quality. When the dirty air needs to be discharged, the blocking component 50 is in the second position. At this time, the first blocking component 501 closes the second air inlet 401, the second blocking component 502 opens the third air outlet 402, the second air outlet 205 is in a closed state, and the exhaust port 204 is in an open state. The indoor dirty air is discharged through the exhaust port 204, the fan component 202, the third air outlet 402, the air duct 40 and the first air inlet 203 in turn, which can improve the indoor air quality and effectively reduce the concentration of harmful gases in the room.

[0050] Figure 5 for Figure 4 Combined with the top view of Figure 5 In some embodiments, to enable the first and second blocking members 501, 502 to operate within the air duct 40, each of the first and second blocking members 501, 502 includes a sealing plate 5011 and a driver 5012. The sealing plate 5011 is disposed within the air duct 40. The driver 5012 is connected to the sealing plate 5011 to drive the sealing plate 5011 to rotate within the air duct 40. The driver 5011 may be a motor.

[0051] Combine Figure 2 and Figure 4In some embodiments, to limit the position of the first blocking member 501 and the second blocking member 502, a first blocking member 403 and a second blocking member 404 are provided in the air duct 40. The first blocking member 403 is located at the edge of the second air inlet 401, and the second blocking member 404 is located at the edge of the third air outlet 402. When the blocking assembly 50 is in the first position, the second blocking member 502 abuts against the second blocking member 404. When the blocking assembly 50 is in the second position, the first blocking member 501 abuts against the first blocking member 403.

[0052] In some embodiments, when the blocking assembly 50 is in the first position, the second blocking member 502 closes the third air outlet 402, and the second blocking member 502 conflicts with the second limiting member 404. The second blocking member 502 is blocked by the second limiting member 404 to avoid excessive movement of the second blocking member 502, thereby limiting the second blocking member 502 and ensuring that the second blocking member 502 can completely block the third air outlet 402, avoiding air leakage and ensuring smooth air flow.

[0053] In some embodiments, when the sealing assembly 50 is in the second position, the first sealing member 501 conflicts with the first limiting member 403, and the first sealing member 501 is blocked by the first limiting member 403 to avoid excessive movement of the first sealing member 501, thereby limiting the first sealing member 501 and ensuring that the first sealing member 501 can completely block the second air inlet 401, avoiding air leakage and ensuring smooth air flow.

[0054] In some embodiments, in order to achieve the limitation of the second blocking member 502, when the blocking assembly 50 is in the first position, the second blocking member 502 conflicts with the volute of the fan assembly 202, and the second blocking member 502 is blocked by the volute of the fan assembly 202 to avoid excessive movement of the second blocking member 502, thereby achieving the limitation of the second blocking member 502 and ensuring that the second blocking member 502 can completely block the third air outlet 402, avoid air leakage, and ensure smooth air flow.

[0055] Combine Figure 1 In some embodiments, in order to facilitate the installation of the air conditioner, the first shell 10 and the second shell 201 are arranged side by side along the length direction of the first shell 10, that is, the second shell 201 is arranged on the side of the first shell 10 to avoid the second shell 201 occupying the height space, thereby reducing the overall height of the air conditioner to facilitate the installation of the first shell 10 and the second shell 201 indoors.

[0056] Of course, in some other embodiments, in the height direction, if there is enough space for installing the fresh air air conditioner, the second shell 201 can also be installed on the top or bottom of the first shell 10.

[0057] Combine Figure 2 In some embodiments, to achieve communication between the second air outlet 205 and the first air outlet 101, the first housing 10 has a side panel 102. The side panel 102 has a vent that communicates with the second air outlet 205. The vent creates an effective air flow path between the second air outlet 205 and the first air outlet 101. Air can flow in from the second air outlet 205, pass through the vent, and ultimately be discharged from the first air outlet 101, achieving smooth air flow. The second housing 201 can be connected to the side panel 102, and the side panel 102 supports the second housing 102.
