[0047] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0048] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can recognize the applicability of other processes and / or the use of other materials.

[0049] Reference is made below Figures 1 to 10 to describe the fresh air component 2 for the air conditioner 100 according to an embodiment of the first aspect of the present invention.

[0050] Referring to Figures 1 to 3 , for the fresh air component 2 of the air conditioner 100 according to an embodiment of the first aspect of the present invention, the air conditioner 100 is provided with a temperature adjustment component 3 which can be used to adjust the temperature of the air flow passing through the air conditioner 100, thereby adjusting the indoor temperature. The temperature adjustment component 3 has an air passage 335 suitable for air flow. The fresh air component 2 may include: a housing 21, a ventilation assembly 22, a first purification assembly 23, and a first adjustment assembly 24. The ventilation assembly 22, the first purification assembly 23, and the first adjustment assembly 24 are all arranged inside the housing 21.

[0051] Specifically, the housing 21 has a fresh air inlet 211, an air inlet 212, and an air outlet 213. Among them, the fresh air inlet 211 is suitable for communicating with the outside. In this way, the fresh air inlet 211 can be used to introduce fresh air from the outside into the room and can also be used to discharge the indoor odor gas or poor-quality air to the outside. For example, when the air conditioner 100 is in the fresh air mode, the fresh air outside can enter the room through the fresh air inlet 211 to change the fresh air in the room. When the air conditioner 100 is in the turbidity discharge mode, the fresh air inlet 211 can be converted into a turbidity discharge outlet for discharging turbidity to the outside; the air inlet 212 is suitable for communicating with the inside of the room, and the air inlet 212 can be used for the circulation of indoor air.

[0052] The housing 21 is provided with a purification air duct 214 and an exhaust air duct 216. The air supply port 213 is adapted to communicate with the air passing duct 335 and the exhaust air duct 216 respectively. The purification air duct 214 can be connected to the fresh air inlet 211 and the air inlet 212 respectively. In this way, the purification air duct 214 can intake air through at least one of the fresh air inlet 211 and the air inlet 212. Moreover, the purification air duct 214 is connected to the exhaust air duct 216 and the air passing duct 335 respectively. In this way, the purification air duct 214 can discharge air to at least one of the exhaust air duct 216 and the air passing duct 335 through the air supply port 213. In other words, the air inlet 212 and the fresh air inlet 211 can serve as the inlets for air to flow into the purification air duct 214 when the air conditioner 100 is in different working modes, and the air supply port 213 can serve as the outlet for air to discharge from the purification air duct 214. Moreover, when the air conditioner 100 switches different working modes, the air supply port 213 can also switch between two states of communicating with the air passing duct 335 and communicating with the exhaust air duct 216, so as to discharge the air flowing through the purification air duct 214 indoors or outdoors to meet different air discharge requirements.

[0053] The ventilation assembly 22 can be arranged in the purification air duct 214. For example, the ventilation assembly 22 can include a fan. In this way, the ventilation assembly 22 can drive the air flow to enter the purification air duct 214 from one of the fresh air inlet 211 and the air inlet 212, and discharge it to one of the exhaust air duct 216 and the air passing duct 335 from the air supply port 213.

[0054] The first purification assembly 23 can be arranged in the purification air duct 214. In this way, when the air conditioner 100 turns on the fresh air function, the first purification assembly 23 can purify the fresh air introduced from the outside, that is, the fresh air and the purification can share the air duct, saving the internal space. Or, the first purification assembly 23 can purify the indoor circulating air, thereby removing floating dust or other impurities in the indoor air, which is beneficial to air renewal and human health.

[0055] The first adjustment assembly 24 can be used to adjust the communication state between the air supply port 213 and the exhaust air duct 216, and can also be used to adjust the communication state between the air supply port 213 and the air passing duct 335. At the same time, the first adjustment assembly 24 can be used to adjust the communication state between the fresh air inlet 211 and the purification air duct 214, and can also be used to adjust the communication state between the fresh air inlet 211 and the exhaust air duct 216.

[0056] For example Figure 2 and Figure 3, As shown, the purification air duct 214 and the air passing duct 335 are arranged at a left - right interval within the housing 21. The exhaust air duct 216 and the purification air duct 214 are on the same side of the air passing duct 335. Among them, the air passing duct 335 extends in the left - right direction, the purification air duct 214 is generally vertically oriented, and the exhaust air duct 216 is also generally vertically oriented. Optionally, the exhaust air duct 216 is located between the purification air duct 214 and the air passing duct 335, and the exhaust air duct 216 and the purification air duct 214 are spaced apart. The air supply port 213 can be located at the top of the purification air duct 214 and the exhaust air duct 216, and the opening is generally along the left - right direction. In this way, the air supply port 213 can serve as both the communication port between the purification air duct 214 and the air passing duct 335 and the communication port between the purification air duct 214 and the exhaust air duct 216, that is, the exhaust air duct 216 and the air passing duct 335 can share the air supply port 213 to facilitate the air flow in the purification air duct 214.

[0057] The ventilation assembly 22 can be disposed within the purification air duct 214. The ventilation assembly 22 is configured to be respectively adapted to communicate with the air inlet 212 and the fresh air inlet 211, so as to drive the outdoor fresh air to enter the purification air duct 214 from the fresh air inlet 211 or drive the indoor air to enter the purification air duct 214 from the air inlet 212, and drive the air flow passing through the purification air duct 214 to be discharged from the air supply port 213 to the air passing duct 335 or the exhaust air duct 216; The first purification assembly 23 can be provided within the purification air duct 214 to purify the air flow passing through the purification air duct 214; The first adjustment assembly 24 can be used to adjust the communication state between the air supply port 213 and the exhaust air duct 216, and can also be used to adjust the communication state between the air supply port 213 and the air passing duct 335. At the same time, the first adjustment assembly 24 can be used to adjust the communication state between the fresh air inlet 211 and the purification air duct 214, and can also be used to adjust the communication state between the fresh air inlet 211 and the exhaust air duct 216.

[0058] The air inlet 212 can be located at a position corresponding to the purification air duct 214 at the top of the housing 21, and the fresh air inlet 211 can be located at the bottom of the housing 21. The fresh air inlet 211 can be configured to communicate with the purification air duct 214 and the exhaust air duct 216 respectively in different modes. In this way, when the air conditioner 100 switches to the fresh air mode, the outdoor fresh air can be introduced into the purification air duct 214 from the fresh air inlet 211 for purification, and finally discharged into the room from the air passing duct 335 through the air supply port 213; When the air conditioner 100 switches to the exhaust mode, the indoor air can enter the purification air duct 214 from the air inlet 212, and successively pass through the air supply port 213 and the exhaust air duct 216, and finally be discharged to the outdoor from the fresh air inlet 211; When the air conditioner 100 switches to the indoor air circulation mode, the indoor air can enter the purification air duct 214 from the air inlet 212 for purification, and successively pass through the air supply port 213 and the air passing duct 335 and then enter the room again.

[0059] Of course, the present invention is not limited thereto. The positions of the fresh air inlet 211 and the air inlet 212 on the housing 21 can also be reasonably designed according to actual needs. The relative positions of the purification air duct 214, the exhaust air duct 216, and the air passing duct 335 can also be reasonably designed according to actual needs. In addition, the numbers of the fresh air inlet 211 and the air inlet 212 can be reasonably designed according to the designed air volume and the air duct layout.

[0060] According to the fresh air component 2 for the air conditioner 100 of the present invention, by arranging the first purification component 23 in the purification air duct 214, connecting the purification air duct 214 to the fresh air inlet 211 and the air inlet 212 respectively, and making the purification air duct 214 be respectively adapted to be connected to the exhaust air duct 216 and the air passing duct 335, the air conditioner 100 can purify the air in both the fresh air mode and the indoor air circulation mode, sterilize the air, so as to better replace the fresh air indoors and improve the indoor air quality. Moreover, when the indoor air is poor, the air purification mode can be enabled to discharge the poor-quality air from the exhaust air duct 216 to the outside. That is, the air conditioner 100 has the functions of replacing fresh air, purifying indoor air, and discharging indoor polluted air at the same time, which can better improve the user experience and is beneficial to the user's physical health. In addition, when the purified air flows through the air passing duct 335, the inside of the air passing duct 335 can also be sterilized.

[0061] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , the purification air duct 214 may have a first ventilation opening 215, the exhaust air duct 216 may have a second ventilation opening 217, and both the first ventilation opening 215 and the second ventilation opening 217 may communicate with the same fresh air inlet 211 (i.e., the fresh air inlet 211 described above). That is to say, the fresh air inlet 211 can form an air flow path with the first ventilation opening 215 and the purification air duct 214, and the fresh air inlet 211 can also form an air flow path with the second ventilation opening 217 and the exhaust air duct 216. The first adjustment component 24 may include a first switching valve 241, and the first switching valve 241 is switchable between a first state and a second state. Wherein, in the first state, the first switching valve 241 closes the first ventilation opening 215 and opens the second ventilation opening 217, and in the second state, the first switching valve 241 closes the second ventilation opening 217 and opens the first ventilation opening 215. In this way, the first switching valve 241 can flexibly adjust the communication state between the fresh air inlet 211 and the purification air duct 214 and the communication state between the fresh air inlet 211 and the exhaust air duct 216 according to the working mode of the air conditioner 100.

[0062] As shown in FIG. 4, the fresh air inlet 211 is formed in a ring shape to facilitate connection with the connecting pipeline. There can be one fresh air inlet 211, which is located at the bottom of the housing 21. The opening direction of the fresh air inlet 211 can be along the front-back direction. The fresh air inlet 211 is generally located below the exhaust air duct 216. Among them, the first ventilation opening 215 of the purification air duct 214 is located at the upper left side of the fresh air inlet 211. The first ventilation opening 215 is inclined relative to the axis of the fresh air inlet 211. The fresh air inlet 211, the first ventilation opening 215, and the purification air duct 214 can define a generally inclined air flow path. The second ventilation opening 217 of the exhaust air duct 216 is located above the fresh air inlet 211. The second ventilation opening 217 is vertically opposite to the axis of the fresh air inlet 211. The fresh air inlet 211, the second ventilation opening 217, and the exhaust air duct 216 define a generally vertically extending air flow path. The first switching valve 241 is rotatably provided at the connection of the first ventilation opening 215 and the second ventilation opening 217.

[0063] When the air conditioner 100 is turned on to the fresh air mode, the first switching valve 241 can be switched to the second state. At this time, the first switching valve 241 opens the second ventilation opening 217 and closes the first ventilation opening 215. The fresh air outdoors can flow through the fresh air inlet 211, the second ventilation opening 217, the purification air duct 214, the air supply opening 213, and the air passing duct 335 in sequence, and finally enter the room to replace the fresh air.

[0064] When the air conditioner 100 is turned on to the exhaust mode, the first switching valve 241 can be switched to the first state. At this time, the first switching valve 241 opens the first ventilation opening 215 and the air inlet 212, and closes the second ventilation opening 217. The air with relatively poor quality indoors can flow through the air inlet 212, the purification air duct 214, the air supply opening 213, the exhaust air duct 216, and the first ventilation opening 215 in sequence, and finally be discharged outdoors from the fresh air inlet 211.

[0065] When the air conditioner 100 is turned on to the indoor air purification mode, the fresh air inlet 211 can be closed, the air inlet 212 can be opened, and the second switching valve 242 can be switched to the third state, that is, the second switching valve 242 opens the second air inlet 331 and closes the first air inlet 218. At this time, the indoor air can flow through the air inlet 212, the purification air duct 214, the air supply opening 213, the second air inlet 331, the air passing duct 335 in sequence and finally be discharged into the room again. Thus, the indoor air can be purified during the circulation process, thereby improving the indoor air quality. Thus, the air conditioner 100 in this embodiment can simultaneously have the functions of replacing fresh air, exhausting turbidity, and purifying indoor air, which is more user-friendly.

[0066] Optionally, there may be two fresh air inlets 211. The opening directions of the fresh air inlets 211 may be arranged in the vertical direction or obliquely. One of the two fresh air inlets 211 communicates with the first ventilation opening 215 and the other communicates with the second ventilation opening 217. At this time, the fresh air inlet 211 connected to the first ventilation opening 215 may only serve as the fresh air inlet of the air conditioner 100 in the fresh air mode, and the fresh air inlet 211 connected to the second ventilation opening 217 may only serve as the exhaust air outlet of the air conditioner 100 in the exhaust air mode. In this way, the air circulation efficiency can be further improved.

[0067] Furthermore, referring to Figure 4 , the first switching valve 241 may include a rotating plate and a pivot shaft. The pivot shaft is provided on one side edge of the rotating plate. The pivot shaft may be provided in the middle of the first ventilation opening 215 and the second ventilation opening 217, that is, the pivot shaft may be provided between the edge of the first ventilation opening 215 and the edge of the second ventilation opening 217. The rotating plate is rotatable about the axis of the pivot shaft. For example, the pivot shaft may be connected to a driving motor to drive the rotation of the rotating plate. The pivot shaft may extend in the front-rear direction such that the rotation trajectory of the rotating plate forms a horizontal column. When the first switching valve 241 is in the first state, the rotating plate may rotate to a position blocking the first ventilation opening 215. When the first switching valve 241 is in the second state, the rotating plate may rotate to a position blocking the second ventilation opening 217. In this way, the overall structure is simple, facilitating manufacturing and assembly, and at the same time, the on-off of the first ventilation opening 215 and the second ventilation opening 217 can be flexibly controlled.

[0068] Optionally, there may be two first switching valves 241. The two first switching valves 241 are respectively provided at the first ventilation opening 215 and the second ventilation opening 217. The first switching valve 241 provided at the first ventilation opening 215 may only be used to control the on-off of the fresh air inlet 211 and the purification air duct 214, and the first switching valve 241 provided at the second ventilation opening 217 may only be used to control the on-off of the fresh air inlet 211 and the exhaust air duct 216. In this way, it is beneficial to efficiently control the air circulation direction and path. Compared with only having one first switching valve 241, the rotation stroke of the rotating plate can be shortened, and the mode switching time of the air conditioner 100 is shorter, which is beneficial to improving the user experience.

[0069] Optionally, the first switching valve 241 may include two rotating plates respectively disposed at the first ventilation opening 215 and the second ventilation opening 217. At this time, when the first switching valve 241 switches to the first state, the rotating plate disposed at the first ventilation opening 215 rotates to a position blocking the first ventilation opening 215, and the rotating plate disposed at the second ventilation opening 217 rotates to an open position to connect the exhaust air duct 216 and the fresh air inlet 211; when the first switching valve 241 switches to the second state, the rotating plate disposed at the first ventilation opening 215 rotates to an open position, and the rotating plate disposed at the second ventilation opening 217 rotates to a position blocking the second ventilation opening 217 to connect the purification duct 214 and the fresh air inlet 211. In this way, the mode switching of the air conditioner 100 takes less time, which is beneficial to improving the user experience.

[0070] According to some embodiments of the present invention, referring to Figure 4 , the exhaust air duct 216 may be formed with a first air inlet 218, the air passing duct 335 may be formed with a second air inlet 331. The second air inlet 331 is formed at one end of the air passing duct 335 along the length direction. Both the first air inlet 218 and the second air inlet 331 are adapted to communicate with the same air supply opening 213. The first adjusting assembly 24 may include a second switching valve 242. The second switching valve 242 is adapted to switch between a third state and a fourth state to adjust the communication state between the air supply opening 213 and the exhaust air duct 216 and the communication state between the air supply opening 213 and the air passing duct 335. Wherein, when the second switching valve 242 is in the third state, the second switching valve 242 can open the second air inlet 331 and close the first air inlet 218. When the second switching valve 242 is in the fourth state, the second switching valve 242 can close the second air inlet 331 and open the first air inlet 218. In this way, the second switching valve 242 can flexibly adjust the communication state between the air supply opening 213 and the air passing duct 335 and the communication state between the air supply opening 213 and the exhaust air duct 216 according to the working mode of the air conditioner 100.

[0071] For example Figure 4 As shown, there may be one air supply opening 213. The air supply opening 213 is located at the top of the purification duct 214. The opening direction of the air supply opening 213 is along the left - right direction. The first air inlet 218 is located at the top of the exhaust air duct 216 and is adjacent to the air supply opening 213. The air supply opening 213, the first air inlet 218 and the exhaust air duct 216 can define an air flow path generally along the vertical direction. The second air inlet 331 is located on the left side of the air passing duct 335 and is opposite to the air supply opening 213 in the left - right direction. The air supply opening 213, the second air inlet 331 and the air passing duct 335 can define an air flow path generally along the horizontal direction. The second switching valve 242 can be disposed at the connection of the first air inlet 218 and the second air inlet 331.

[0072] When the air conditioner 100 turns on the fresh air mode, the first switching valve 241 can be switched to the second state, and the second switching valve 242 can be switched to the third state. At this time, the first switching valve 241 opens the first ventilation opening 215 and closes the second ventilation opening 217, and the second switching valve 242 opens the second air inlet 331 and closes the first air inlet 218. The fresh air outdoors can flow through the fresh air opening 211, the first ventilation opening 215, the purification air duct 214, the air supply opening 213, the second air inlet 331, and the air passing air duct 335 in sequence, and finally enter the room to replace the fresh air.

[0073] When the air conditioner 100 turns on the exhaust mode, the first switching valve 241 can be switched to the first state, and the second switching valve 242 can be switched to the fourth state. At this time, the first switching valve 241 opens the second ventilation opening 217 and the air inlet 212 and closes the first ventilation opening 215, and the second switching valve 242 opens the first air inlet 218 and closes the second air inlet 331. The air with relatively poor quality indoors can flow through the air inlet 212, the purification air duct 214, the air supply opening 213, the first air inlet 218, the exhaust air duct 216, and the second ventilation opening 217 in sequence, and finally be discharged outdoors from the fresh air opening 211.

[0074] When the air conditioner 100 turns on the indoor air purification mode, the fresh air opening 211 can be closed and the air inlet 212 can be opened. At this time, the first switching valve 241 can be switched to the first state, and the second switching valve 242 can be switched to the third state, that is, the second switching valve 242 opens the second air inlet 331 and closes the first air inlet 218. At this time, the indoor air can flow through the air inlet 212, the purification air duct 214, the air supply opening 213, the second air inlet 331, the air passing air duct 335, and finally be discharged into the room again. Thus, the indoor air can be purified during the circulation process, thereby improving the indoor air quality; thus, the air conditioner 100 in this embodiment can simultaneously have the functions of replacing fresh air, purifying indoor air, and exhausting turbidity, which is more user-friendly.

[0075] Optionally, there can also be two air supply openings 213. One of the two air supply openings 213 is connected to the first air inlet 218, and the other is connected to the second air inlet 331. At this time, the air supply opening 213 connected to the first air inlet 218 can only be used as the exhaust opening of the purification air duct 214 when the air conditioner 100 is in the exhaust mode, and the air supply opening 213 connected to the second air inlet 331 can be used as the exhaust opening of the purification air duct 214 when the air conditioner 100 is in the fresh air mode and the indoor air purification mode. In this way, the air circulation efficiency can be further improved.

[0076] Further, referring to Figures 3 to 6The second switching valve 242 may include a translatable translation member. For example, the translation member may be configured to be suitable for lifting and lowering movement in the up-and-down direction, or for telescopic movement in the front-and-rear direction (i.e., the direction perpendicular to the wall), or for translation movement in the left-and-right direction. A connecting air duct may be defined in the translation member. When the second switching valve 242 is switched to the third state, the translation member may be translated to a position avoiding the air supply port 213 and the second air inlet 331, and the connecting air duct is blocked from at least one of the air supply port 213 and the first air inlet 218. That is to say, when the second switching valve 242 is switched to the third state, the translation member may be translated to a position connecting the air supply port 213 and the second air inlet 331. For example, the translation member may be translated to the first air inlet 331 is connected to the air supply port 213, and the opening on the left side wall of the translation member is connected to the first air inlet 218. Alternatively, the translation member can be retracted backward to connect the air supply port 213 and the second air inlet 331; when the second switching valve 242 is switched to the fourth state, the translation member can be translated to a position blocking the second air inlet 331, and the connecting air duct is respectively connected to the air supply port 213 and the first air inlet 218. For example, the translation member can be translated to the upper side of the first air inlet 218. At this time, the right side wall of the translation member can separate the second air inlet 331, the opening on the left side wall of the translation member is connected to the air supply port 213, and the opening on the bottom wall of the translation member is connected to the first air inlet 218. Thus, the connecting air duct can be respectively connected to the air supply port 213 and the first air inlet 218.

[0077] For example Figure 5 As shown, the translation member is roughly formed into a square shape, and a connecting air duct is defined on the inner side of the translation member. In the vertical direction, the translation member is telescopically arranged on the upper side of the first air inlet 218 along the front-to-back direction. In the left-to-right direction, the translation member is arranged between the air supply port 213 and the second air inlet 331. The connecting air duct of the translation member has a first opening and a second opening. The first opening is located on the left side wall of the translation member, and the second opening is located on the bottom wall of the translation member. When the second switching valve 242 is switched to the third state, the translation member retracts backward, so that the air supply port 213 and the second air inlet 331 are connected. When the second switching valve 242 is switched to the fourth state, the translation member extends forward, so that the translation member can block the air supply port 213 and the second air inlet 331 in the left-to-right direction. At the same time, the connecting air duct of the translation member is connected with the air supply port 213 through the first opening, and is connected with the first air inlet 218 through the second opening, thereby realizing the connection between the air supply port 213 and the first air inlet 218 in the fourth state.

[0078] Optionally, the translation member is generally formed in a square shape. The inner side of the translation member defines a connecting air duct. The translation member is configured to move along the opening direction of the first air inlet 218, i.e., the vertical direction. The connecting air duct of the translation member has a first opening and a second opening. The first opening is located on the left side wall of the translation member, and the second opening is located on the bottom wall of the translation member. When the second switching valve 242 is switched to the third state, the translation member descends into the first air inlet 218, so that the air outlet 213 and the second air inlet 331 are connected while the first air inlet 218 is blocked. When the second switching valve 242 is switched to the fourth state, the translation member rises, so that the translation member can block the air outlet 213 and the second air inlet 331 in the left-right direction. At the same time, the connecting air duct of the translation member is connected to the air outlet 213 through the first opening and connected to the first air inlet 218 through the second opening, so as to realize the connection between the air outlet 213 and the first air inlet 218 in the fourth state.

[0079] Optionally, there may be two second switching valves 242. The two second switching valves 242 are respectively arranged at the first air inlet 218 and the second air inlet 331. The second switching valve 242 arranged at the second air inlet 331 can be only used to control the on-off of the purification air duct 214 and the air passing duct 335. The second switching valve 242 arranged at the first air inlet 218 can be only used to control the on-off of the purification air duct 214 and the exhaust air duct 216. At this time, the translation member can only perform a telescopic movement, and the connecting air duct may not be provided on the translation member. In this way, it is beneficial to efficiently control the air flow direction and path. Compared with only one second switching valve 242, the mode switching time of the air conditioner 100 is shorter, which is beneficial to improving the user experience.

[0080] Optionally, the second switching valve 242 may also include two translation members. The two translation members are respectively arranged at the first air inlet 218 and the second air inlet 331. At this time, both translation members can perform telescopic movements along the front-rear direction, and the connecting air duct may not be provided on the translation member. When the second switching valve 242 is switched to the third state, the translation member arranged at the first air inlet 218 extends to block the first air inlet 218 and the air outlet 213, and the translation member arranged at the second air inlet 331 can retract to connect the air outlet 213 and the second air inlet 331. When the second switching valve 242 is switched to the fourth state, the translation member arranged at the first air inlet 218 retracts to connect the first air inlet 218 and the air outlet 213, and the translation member arranged at the second air inlet 331 can extend to block the air outlet 213 and the second air inlet 331. In this way, the mode switching time of the air conditioner 100 is shorter, which is beneficial to improving the user experience.

[0081] According to some embodiments of the present invention, refer to Figure 3 and Figure 4, the first adjustment component 24 can also be used to adjust the opening and closing state of the air inlet 212. For example, when the air conditioner 100 is in the indoor air purification mode, the first adjustment component 24 can open the air inlet 212. At this time, indoor air can enter the purification air duct 214 for purification and then flow back into the room through the air passing duct 335 to achieve circulation. When the air conditioner 100 is in the turbidity discharge mode, the first adjustment component 24 can open the air inlet 212. At this time, the indoor air with relatively poor quality can be discharged to the outside through the exhaust air duct 216 from the fresh air inlet 211.

[0082] Of course, the present invention is not limited to this. It is also possible not to control the opening and closing of the air inlet 212, that is, the air inlet 212 is in a normally open state. At this time, the air conditioner 100 can purify the indoor air in different modes.

[0083] In some embodiments, referring to Figures 3 to 6 , the first purification component 23 can be located upstream of the ventilation component 22. That is to say, in the fresh air mode of the air conditioner 100, the outdoor air entering the purification air duct 214 from the fresh air inlet 211 first passes through the first purification component 23 for purification and then passes through the ventilation component 22 and is sent to the air passing duct 335 and finally enters the room; in the indoor air purification mode of the air conditioner 100, the indoor air entering the purification air duct 214 from the air inlet 212 first passes through the first purification component 23 for purification and then flows into the room through the air passing duct 335 under the drive of the ventilation component 22; in the turbidity discharge mode of the air conditioner 100, the indoor air entering the purification air duct 214 from the air inlet 212 can also first pass through the purification of the first purification component 23 and then be discharged to the outside through the exhaust air duct 216 under the drive of the ventilation component 22.

[0084] In a specific example, referring to Figure 4 , the ventilation component 22 can be a double-suction centrifugal impeller. That is to say, the ventilation component 22 can suck air from two directions. The air inlet 212 can include a first sub-inlet 2121 and a second sub-inlet 2122. The first sub-inlet 2121 and the second sub-inlet 2122 are respectively arranged on both sides of the double-suction centrifugal impeller along the axial direction. The first purification component 23 can include a first purification module 231 and a second purification module 232. Among them, the first purification module 231 is correspondingly and oppositely arranged with the first sub-inlet 2121, and the second purification module 232 is correspondingly and oppositely arranged with the second sub-inlet 2122.

[0085] For example Figure 4As shown, the axial direction of the double-suction centrifugal air wheel is along the vertical direction, that is, the two air inlets of the double-suction centrifugal air wheel are respectively located on its upper side and lower side. The air inlet 212 may include a first sub-inlet 2121 and a second sub-inlet 2122. The first sub-inlet 2121 is provided at the top of the housing 21 and is arranged vertically opposite to the upper air inlet of the double-suction centrifugal air wheel. The second sub-inlet 2122 is located at the bottom of the housing 21 and is arranged vertically opposite to the lower air inlet of the double-suction centrifugal air wheel. The first purification component 23 may include a first purification module 231 and a second purification module 232. The first purification module 231 is provided between the first sub-inlet 2121 and the upper air inlet of the double-suction centrifugal air wheel. The second purification module 232 is provided between the second sub-inlet 2122 and the lower air inlet of the double-suction centrifugal air wheel. Thus, the air entering the purification air duct 214 must first pass through the purification and impurity removal of the purification module and then flow into the room, thereby improving the air quality in the room. Of course, the present invention is not limited thereto. The first purification module 231 may also be provided outside the first sub-inlet 2121. For example, a receiving groove is formed on the upper surface of the housing 21, and the bottom wall of the receiving groove forms the first sub-inlet 2121. The first purification module 231 may be embedded in the receiving groove. Thus, it is beneficial to reduce the overall volume of the air conditioner 100, thereby saving space and facilitating assembly and maintenance.

[0086] Furthermore, the compositions of the first purification module 231 and the second purification module 232 are different. For example, activated carbon may be provided in the first purification module 231 to remove the peculiar smell or sterilize the indoor air. Multiple filter meshes may be provided in the second purification module 232 to filter floating dust and other impurities in the air. In addition, the first purification module 231 and the second purification module 232 may also be configured into different structures according to different purification functions to be achieved and different connection positions on the housing 21. Optionally, both the first purification module 231 and the second purification module 232 may be high air resistance modules, which is beneficial to fully purify and sterilize the outdoor fresh air and indoor air.

[0087] In some embodiments, referring to Figure 3 and Figure 4 , the first adjustment component 24 may further include a first switching valve and a second switching valve. The first switching valve is provided at the first sub-inlet 2121, and the first switching valve serves as a switch for adjusting the first sub-inlet 2121. The second switching valve is provided at the second sub-inlet 2122, and the second switching valve serves as a switch for adjusting the second sub-inlet 2122. Thus, the air conditioner 100 can control the first sub-inlet 2121 and the second sub-inlet 2122 respectively, so as to flexibly control the air volume according to requirements.

[0088] Optionally, both the first switching valve and the second switching valve may be formed into louver structures. In this way, the structure is simple and convenient for manufacturing and assembly.

[0089] According to some embodiments of the present invention, the first purification component 23 may include one or more purification modules, and at least one purification module is detachable relative to the housing 21. For example, the first purification component 23 may include a first purification module 231 and a second purification module 232. The first purification module 231 is disposed between the first sub-inlet 2121 and the upper air suction port of the double-suction centrifugal air wheel, and the second purification module 232 is disposed between the second sub-inlet 2122 and the lower air suction port of the double-suction centrifugal air wheel. The first purification module 231 may be detachably connected to the housing 21, such as by snap connection, and the second purification module 232 may be bolted to the inner wall of the housing 21, so that the cleaning or replacement of the first purification component 23 can be realized.

[0090] For example Figure 4 As shown, a receiving groove is formed on the upper surface of the housing 21, the bottom wall of the receiving groove is formed as the first sub-inlet 2121, the first purification block is formed in a block shape adapted to the receiving groove, and the first purification module 231 can be embedded in the receiving groove and snap-connected to the side wall of the receiving groove; a horizontal mounting plate is formed on the inner wall of the housing 21, and both ends of the second purification module 232 are disposed on the mounting plate and bolted to the mounting portion. Thus, the structure is simple and convenient for installation and disassembly.

[0091] Next, reference is made to Figures 1 to 10 describe the air conditioner 100 according to the embodiment of the second aspect of the present invention.

[0092] Reference is made to Figures 1 to 3 , the air conditioner 100 according to the embodiment of the second aspect of the present invention includes: a temperature adjustment component 3 and a fresh air component 2 according to the above embodiment of the present invention.

[0093] Specifically, the temperature adjustment component 3 may define an air outlet duct 335, the fresh air component 2 may be arranged side by side with the temperature adjustment component 3 left and right, and the fresh air component 2 may include: a housing 21, a ventilation component 22, a first purification component 23, and a first adjustment component 24.

[0094] Among them, a fresh air inlet 211, an air inlet 212, and an air outlet 213 are formed on the housing 21. A purification duct 214 and an exhaust duct 216 are defined inside the housing 21. Among them, the fresh air inlet 211, the air inlet 212, and the air outlet 213 are all communicated with the purification duct 214. The fresh air inlet 211 may be used as the outdoor air circulation inlet of the purification duct 214, the air inlet 212 may be used as the indoor air circulation inlet of the purification duct 214, the air outlet 213 may be used as the air circulation outlet of the purification duct 214, and the purification duct 214 may blow air to at least one of the air outlet duct 335 or the exhaust duct 216 through the air outlet 213.

[0095] The ventilation component 22 can be disposed in the purification air duct 214, and the first purification component 23 can be arranged in the purification air duct 214. In this way, when the air conditioner 100 turns on the fresh air function, the first purification component 23 can purify the fresh air introduced from the outside, or the first purification component 23 can purify the indoor circulating air, thereby removing floating dust or other impurities in the indoor air, which is beneficial to air replacement and human health. The first adjustment component 24 can be used to adjust the connection state between the air supply port 213 and the exhaust air duct 216, and can also be used to adjust the connection state between the air supply port 213 and the air passing duct 335. At the same time, the first adjustment component 24 can be used to adjust the connection state between the fresh air port 211 and the purification air duct 214, and can also be used to adjust the connection state between the fresh air port 211 and the exhaust air duct 216.

[0096] According to the air conditioner 100 of the embodiment of the present invention, by providing the fresh air component 2 of the above embodiment, not only can fresh air be introduced into the room, but also the indoor air can be circulated and purified, and the dirty air in the room can be discharged outdoors. That is, the air conditioner 100 can work in different working modes according to needs, flexibly adjust and improve the indoor air quality, better enhance the user experience, and be beneficial to the user's physical health.

[0097] Further, referring to Figures 1 to 3 and Figures 8 to 10 , the air conditioner 100 may further include a housing 1. A first housing outlet 13 and a second housing outlet 14 may be formed on the housing 1. The temperature adjustment component 3 is disposed in the housing 1. The temperature adjustment component 3 may include: a first air duct assembly 31, a heat exchange component 32, a second air duct assembly 33, and a second adjustment component.

[0098] Specifically, the first air duct assembly 31 can define a heat exchange air duct 311, and the outlet of the heat exchange air duct 311 can communicate with the first housing outlet 13; the heat exchange assembly 32 is arranged upstream of the heat exchange air duct 311. That is to say, when the air flow passes through the air flow temperature adjustment component 3, it will first pass through the heat exchange assembly 32 for heat exchange and then flow through the heat exchange air duct 311 and be discharged; the second air duct assembly 33 can define an air passing air duct 335, and the second air inlet 331 of the air passing air duct 335 communicates with the air supply port 213 of the purification air duct 214 defined by the fresh air component 2. The air passing air duct 335 has a first air outlet 333 and a second air outlet 334. In the flowing direction of the fresh air, the first air outlet 333 is arranged upstream of the heat exchange assembly 32. That is, the fresh air first enters the air passing air duct 335 of the second air duct assembly 33, and then is discharged from the first air outlet 333 of the air passing air duct 335 and then flows through the front evaporation and middle evaporation of the heat exchange assembly 32 to improve the heat exchange efficiency; the second air outlet 334 communicates with the second housing outlet 14, and the second adjustment assembly is used to adjust the opening states of the first air outlet 333 and the second air outlet 334. Thus, the air conditioner 100 of this embodiment can control the flowing direction of the air flow on the side of the temperature adjustment component 3 by controlling the opening states of the first air outlet 333 and the second air outlet 334, so as to control whether the air flow performs heat exchange, and output an air flow with a temperature meeting the requirements.

[0099] For example Figure 8 As shown, a first housing outlet 13 and a second housing outlet 14 are formed on the housing 1 of the air conditioner 100. Among them, the first housing outlet 13 is located at the connection of the front panel and the bottom panel of the housing 21, and the opening direction of the first housing outlet 13 can be inclined downward. The second housing outlet 14 is located on the front panel of the housing 21, and the second housing outlet 14 is located above the first housing outlet 13.

[0100] The temperature adjustment component 3 arranged inside the housing 1 has a first air duct assembly 31, a heat exchange assembly 32, a second air duct assembly 33 and a second adjustment assembly. Among them, the second air duct assembly 33 is arranged at a position close to the front panel and the top panel of the housing 1, and the first air duct assembly 31 is located at the lower part at the rear side of the second air duct assembly 33. Taking the flowing direction of the fresh air in the fresh air mode of the air conditioner 100 as an example for description:

[0101] In the flow direction of the fresh air, the second air duct assembly 33 is located upstream of the first air duct assembly 31. The second air duct assembly 33 defines an air passing duct 335. The second air inlet 331 of the air passing duct 335 is communicated with the air supply port 213 of the purification air duct 214 of the fresh air component 2. The second air outlet 334 of the air passing duct 335 and the second housing outlet 14 of the housing 1 are arranged opposite to each other front and back, that is, the opening direction of the second air outlet 334 is along the front-back direction and faces the second housing outlet 14. The first air outlet 333 of the air passing duct 335 is arranged obliquely opposite to the first air duct assembly 31, and the first air outlet 333 is located behind the second air outlet 334. The opening direction of the first air outlet 333 is inclined backward and downward. The plane where the second air outlet 334 is located and the plane where the first air outlet 333 is located form an acute angle approximately.

[0102] The first air duct assembly 31 defines a heat exchange air duct 311. The inlet of the heat exchange air duct 311 is arranged obliquely opposite to the first air outlet 333. The outlet of the heat exchange air duct 311 is communicated with the first housing outlet 13 of the housing 1. At least a part of the heat exchange component 32 is arranged obliquely between the heat exchange air duct 311 and the first air outlet 333 of the air passing duct 335. In this way, when it is necessary to heat or cool the fresh air, after the outdoor fresh air flows from the fresh air component 2 side into the temperature adjustment component 3 side, it first enters the air passing duct 335 from the second air inlet 331 (the second air inlet 331 of the air passing duct 335 described above), then can flow out of the air passing duct 335 from the first air outlet 333, and then enters the heat exchange air duct 311 of the first air duct assembly 31 after heat exchange through the heat exchange component 32, and then is discharged into the room in sequence through the outlet of the heat exchange air duct 311 and the first housing outlet 13 located at the lower end of the housing 1. In addition, the fresh air passing through the heat exchange air duct 311 can sterilize and purify the heat exchange air duct 311.

[0103] Of course, when the fresh air does not need heat exchange, after the outdoor fresh air flows from the fresh air component 2 side into the temperature adjustment component 3 side, it first enters the air passing duct 335 from the second air inlet 331 (the second air inlet 331 of the air passing duct 335 described above), and then is discharged into the room in sequence through the second air outlet 334 and the second housing outlet 14 of the front panel of the housing 1.

[0104] It can be understood that on the temperature adjustment component 3 side of the air conditioner 100, the flow direction of the indoor air in the indoor air purification mode is the same as the flow direction of the outdoor air in the fresh air mode (including the two flow directions of refrigeration and heating). The only difference is that on the fresh air component 2 side of the air conditioner 100, the indoor air flows into the purification air duct 214 from the air inlet 212 in the indoor air purification mode, while the outdoor air flows into the purification air duct 214 from the fresh air inlet 211 in the fresh air mode.

[0105] Optionally, the second air duct assembly 33 can be detachably connected to the heat exchange assembly 32 or the inner wall of the casing 1, such as by snap connection, for convenient disassembly, assembly and later maintenance.

[0106] In a specific example, the heat exchange assembly 32 can include a heat exchanger.

[0107] Furthermore, referring to Figure 1 and Figure 3 , a first casing inlet 11 and a second casing inlet 12 are formed on the casing 1. The fresh air component 2 is disposed inside the casing 1, and the first casing inlet 11 communicates with the air inlet 212 of the fresh air component 2. A third air inlet 332 is formed in the air passing duct 335. Both the third air inlet 332 and the inlet of the heat exchange duct 311 are adapted to communicate with the second casing inlet 12. The second adjustment assembly is further configured to adjust the on-off state of the third air inlet 332. Thus, the structure is simple and convenient for manufacturing.

[0108] As shown in the figure for example, both the first casing inlet 11 and the second casing inlet 12 are formed at the top of the casing 1 and are spaced apart in the left-right direction. The first casing inlet 11 and the air inlet 212 (such as the first sub-inlet 2121) of the fresh air component 2 are vertically opposite and communicate with each other, so as to facilitate the air intake of the fresh air component 2 when the air conditioner 100 is in the indoor air purification mode and the turbidity discharge mode. The second casing inlet 12 is located on the side of the temperature adjustment component 3. The third air inlet 332 is formed at the top of the air passing duct 335. The second casing inlet 12 is simultaneously located above both the third air inlet 332 and the inlet of the heat exchange duct 311. At this time, a part of the heat exchange assembly 32 is located between the second casing inlet 12 and the heat exchange duct 311. In this way, when the air conditioner 100 is in the indoor air circulation mode, the indoor air can directly enter the side of the temperature adjustment component 3 from the second casing inlet 12, then flow through the heat exchange assembly 32 to the heat exchange duct 311 and finally enter the room again, or it can also first enter the air passing duct 335 from the third air inlet 332, then sequentially pass through the first air outlet 333 of the air passing duct 335, the heat exchange assembly 32 and enter the heat exchange duct 311, and finally enter the room again.

[0109] Furthermore, the temperature adjustment component 3 can further include a second purification component 34. Specifically, in the flowing direction of the indoor air, the second purification component 34 is arranged upstream of the third air inlet 332 and the heat exchange assembly 32. That is to say, after the indoor air enters the side of the temperature adjustment component 3 from the second casing inlet 12, it is first purified by the second purification component 34, and then, according to the working mode of the air conditioner 100, it is selected to flow into the air passing duct 335 from the third air inlet 332 or directly pass through the heat exchange assembly 32 and enter the heat exchange duct 311. Thus, the purification of the indoor air can be realized, the indoor air quality can be improved, and it is beneficial to the health of users.

[0110] In a specific example, the second purification component 34 includes a plurality of third purification modules, which are arranged along the length direction of the housing 1, and the third purification module can be a low air resistance purification module.

[0111] According to some embodiments of the present invention, the air conditioner 100 is a wall-mounted air conditioner 100, the length direction of the air conditioner 100 extends horizontally, and the temperature adjustment component 3 and the fresh air component 2 are arranged horizontally. For example Figure 2 As shown, the temperature adjustment component 3 and the fresh air component 2 are arranged in the left-right direction, and the fresh air component 2 is located on the left side of the temperature adjustment component 3. In this way, the structure is simple.

[0129] In the normal mode, the indoor air can sequentially enter the air passing duct 335 through the second housing inlet 12 of the housing 1 and the third air inlet 332 of the air passing duct 335, and then is discharged from the first air outlet 333 of the air passing duct 335, enters the heat exchange duct 311 after heat exchange through the heat exchanger, and finally is discharged into the room through the outlet of the heat exchange duct 311 and the first housing outlet 13 of the housing 1.

At this time, the air conditioner 100 can cool or heat the fresh air.

[0160] In the indoor air purification mode, the first switching valve 241 is switched to the first state, and the second switching valve 242 is switched to the third state. At this time, the fresh air opening 211 is closed, and at the same time, the communication between the exhaust air duct 216 and the purification air duct 214 is blocked. The indoor air can enter the purification air duct 214 for purification in sequence through the first housing inlet 11 on the housing 1 and the air inlet 212 of the fresh air component 2. The purified indoor air enters the air passing air duct 335 in sequence through the air supply opening 213 and the second air inlet 331, and then is discharged from the first air outlet 333 of the air passing air duct 335, passes through the heat exchanger for heat exchange and then enters the heat exchange air duct 311, and finally is discharged into the room in sequence through the outlet of the heat exchange air duct 311 and the first housing outlet 13 of the housing 1. At this time, the air conditioner 100 can cool or heat the indoor air.

[0161] In the exhaust mode, the first switching valve 241 switches to the first state, and the second switching valve 242 switches to the fourth state.

The second switching valve 242 opens the first air inlet 218 and closes the second air inlet 331. At the same time, the air inlet 212 is opened, and the indoor air can enter the purification air duct 214 in sequence through the first housing inlet 11 on the housing 1 and the air inlet 212 of the fresh air component 2. Then, it enters the exhaust air duct 216 in sequence through the air supply port 213 of the purification air duct 214 and the first air inlet 218, and finally is discharged outdoors through the second ventilation port 217 and the fresh air port 211 of the exhaust air duct 216.

[0162] In the normal mode, a part of the indoor air can enter the air passing duct 335 in sequence through the second housing inlet 12 of the housing 1 and the third air inlet 332 of the air passing duct 335, and another part can enter the purification air duct 214 through the first housing inlet 11 on the housing 1 and the air inlet 212 of the fresh air component 2 for purification. The purified indoor air enters the air passing duct 335 in sequence through the air supply port 213 and the second air inlet 331, and then the air flow in the air passing duct 335 is discharged from its first air outlet 333, enters the heat exchange air duct 311 after heat exchange through the heat exchanger, and finally is discharged into the room in sequence through the outlet of the heat exchange air duct 311 and the first housing outlet 13 of the housing 1.
