[0054] Below, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present application is described.

[0055] Among them, the air conditioner 100 can be a cabinet air conditioner, or a wall-mounted air conditioner, etc., of course, the air conditioner 100 can be an integrated air conditioner (such as a window air conditioner, a mobile air conditioner, etc.), or a split air conditioner. In the following description of the present application, the air conditioner 100 is taken as an example of a cabinet air conditioner, and those skilled in the art will easily understand the technical solutions of the air conditioner 100 as other types of air conditioners after reading the following technical solutions.

[0056] As shown in Figures 1-4 The air conditioner 100 includes a shell 1, the shell 1 has a first air duct 10a and a second air duct 10b inside, and the shell 1 has an air inlet 1a, a first air outlet 1b and a second air outlet 1c, the air inlet 1a and the first air outlet 1b are both communicated with the first air duct 10a, and the second air outlet 1c is communicated with the second air duct 10b, then the air outside the shell 1 can flow into the first air duct 10a through the air inlet 1a, and be blown out through the first air outlet 1b to realize the air outlet of the air conditioner 100, and the air flowing into the second air duct 10b can be blown out through the second air outlet 1c to realize the air outlet of the air conditioner 100.

[0057] The air conditioner 100 further includes a heat exchange component 2, the heat exchange component 2 is arranged in the first air duct 10a, then the air flowing through the first air duct 10a can exchange heat with the heat exchange component 2 to adjust the ambient temperature.

[0058] The air conditioner 100 further includes a first ventilation component 3 and a second ventilation component 4, the first ventilation component 3 includes a first fan 31 arranged in the first air duct 10a, then the first fan 31 operates to drive the air flow in the first air duct 10a to generate negative pressure at the air inlet 1a, and can drive the air in the first air duct 10a to flow towards the first air outlet 1b; the second ventilation component 4 includes a second fan 41 arranged in the second air duct 10b, then the second fan 41 operates to drive the air flow in the second air duct 10b to flow towards the second air outlet 1c.

[0059] The operation control of the first air fan 31 and the second air fan 41 can be set according to actual application. For example, the first air fan 31 and the second air fan 41 can be configured to operate when the air conditioner 100 operates, that is, the first air fan 31 and the second air fan 41 operate in any state as long as the air conditioner 100 is turned on; or the first air fan 31 and the second air fan 41 can be configured to operate when at least one of the first air fan 31 and the second air fan 41 operates when the air conditioner 100 operates, that is, at least one of the first air fan 31 and the second air fan 41 operates in any state as long as the air conditioner 100 is turned on; or the first air fan 31 and the second air fan 41 can be configured to operate when the first air fan 31 operates when the air conditioner 100 operates, and the second air fan 41 can be switched freely, that is, the first air fan 31 operates in any state as long as the air conditioner 100 is turned on, and the second air fan 41 can operate when the corresponding function is turned on; or the first air fan 31 and the second air fan 41 can also be configured to operate when the second air fan 41 operates when the air conditioner 100 operates, and the first air fan 31 can be switched freely, that is, the second air fan 41 operates in any state as long as the air conditioner 100 is turned on, and the first air fan 31 can operate when the corresponding function is turned on.

[0060] In the following description, the first air fan 31 and the second air fan 41 are taken as an example for description, and those skilled in the art can easily understand the technical solutions of other operation modes of the first air fan 31 and the second air fan 41 after reading the following technical solutions.

[0061] The air conditioner 100 further comprises an air duct switching component 6, the air duct switching component 6 comprises a third air duct 610, the air duct switching component 6 has a first switching state and a second switching state, and the air duct switching component 6 can be switched between the first switching state and the second switching state. In the first switching state (as shown in Figure 3 ), the third air duct 610 communicates the second air duct 10b and the first air duct 10a, at this time, the airflow at the air inlet 1a flows into the first air duct 10a, part of the airflow in the first air duct 10a can be blown out through the first air outlet 1b, and the other part of the airflow in the first air duct 10a can flow into the second air duct 10b through the third air duct 610; in the second switching state (as shown in Figure 4 ), the third air duct 610 communicates the second air duct 10b and the air inlet 1a, at this time, part of the airflow at the air inlet 1a can directly flow into the first air duct 10a, the airflow in the first air duct 10a can be blown out through the first air outlet 1b, and the other part of the airflow at the air inlet 1a flows into the second air duct 10b through the third air duct 610.

[0062] AsFigure 3 and Figure 4 As shown in FIG. 6, the air duct switching component 6 further comprises a heater 64 arranged in the third air duct 610. When the heater 64 is in operation, the air flowing through the third air duct 610 can be heated, so as to improve the heating capacity of the air conditioner 100, and to better adjust the indoor temperature. The heated air can be blown out through the second air outlet 1c, so as to improve the air outlet temperature of the second air outlet 1c, and to improve the overall air outlet temperature of the air conditioner 100.

[0063] For example, the air conditioner 100 is used for heating, and when the heater 64 is in operation, if the air duct switching component 6 is in the first switching state, the air at the air inlet 1a flows into the first air duct 10a. Part of the air in the first air duct 10a can be blown out through the first air outlet 1b as hot air after heat exchange with the heat exchange component 2. Another part of the air in the first air duct 10a can flow into the second air duct 10b through the third air duct 610. Since the heater 64 is arranged in the third air duct 640, the air in the third air duct 610 is heated and then flows into the second air duct 10b, so that the second air outlet 1c blows out hot air after heat exchange with the heater 64. In the first switching state, the air duct switching component 6 can make the third air duct 610 communicate with the downstream side of the heat exchange component 2, that is, the third air duct 610 communicates with the part of the first air duct 10a located on the downstream side of the heat exchange component 2, so that the second air outlet 1c blows out hot air after heat exchange with the heat exchange component 2 and the heater 64.

[0064] If the air duct switching component 6 is in the second switching state, part of the air at the air inlet 1a can directly flow into the first air duct 10a. The air in the first air duct 10a is heat exchanged with the heat exchange component 2 and then blown out through the first air outlet 1b. Another part of the air at the air inlet 1a flows into the second air duct 10b through the third air duct 610, and the second air outlet 1c blows out hot air after heat exchange with the heater 64.

[0065] It can be seen that the air conditioner 100 can be used for heating to improve the ambient temperature. When the air conditioner 100 needs to provide more heating capacity, the heater can be turned on to improve the air outlet temperature of the air conditioner 100, so as to ensure the thermal comfort of the user. At the same time, the air duct switching component 6 can be used to appropriately adjust the air outlet temperatures of the first air outlet 1b and the second air outlet 1c.

[0066] It can be understood that when the air conditioner 100 blows air through the first air outlet 1b and the second air outlet 1c, it is beneficial to expand the air supply range of the air conditioner 100, and to improve the applicability of the air conditioner 100 by cooperating with other functions of the air conditioner 100.

[0067] According to the air conditioner 100 of the embodiment of the present application, the operation mode of the air conditioner 100 is enriched by arranging the air duct switching component 6, and the air duct switching component 6 comprises the heater 64, the heater 64 can be used to heat the airflow of the third air duct 610, and the heater 64 cooperates with the different switching states of the air duct switching component 6, so as to adjust the outlet air temperature of the air conditioner 100 in different operation modes within a certain range, so as to make the heating capacity of the air conditioner 100 better meet the actual differentiated needs, and improve the user thermal comfort.

[0068] Optionally, the heater 64 can be an electric auxiliary heater.

[0069] In some embodiments of the present application, as shown in Figure 2 and Figure 5 , the shell 1 has a pull-out opening 1e, the pull-out opening 1e is opposite to the second air duct 10b, and the pull-out opening 1e is located on the side of the second air outlet 1c close to the third air duct 610 on the airflow flow path of the second air duct 10b, and the air conditioner 100 further comprises a storage rack 5 which is pullably arranged at the pull-out opening 1e, which facilitates the disassembly and assembly of the storage rack 5, and when the storage rack 5 is installed at the pull-out opening 1e, the storage rack 5 can be located upstream of the second air outlet 1c, and at least part of the airflow in the second air duct 10b flows through the storage rack 5 before flowing to the second air outlet 1c.

[0070] Therefore, when the heater 64 is turned on and / or the air conditioner 100 is used for heating, hot air can flow through the storage rack 5, and if articles such as clothes, shoes, etc. are placed on the storage rack 5, the air conditioner 100 can dry the articles on the storage rack 5. For example, when drying is needed, if the air conditioner 100 is used for heating, the air duct switching component 6 can be switched to the first switching state, so that part of the airflow after heat exchange flows into the second air duct 10b and dries the articles to be dried on the storage rack 5 to remove moisture, and finally flows out through the second air outlet 1c; or if the air conditioner 100 is in a non-heating state such as refrigeration or shutdown, the air duct switching component 6 can be switched to the second switching state, and at this time the heater 64 can be used to heat the airflow to achieve drying. It can be understood that when the drying is completed, the storage rack 5 can be pulled outwards to facilitate taking out the articles on the storage rack 5.

[0071] It can be seen that the air conditioner 100 can realize the drying function through the second air duct 10b, without separately arranging a drying air duct, which is beneficial to simplify the structure of the air conditioner 100 and reduce the cost.

[0072] Optionally, in Figure 2 , Figure 3 and Figure 14In the example, the second ventilation component 4 includes an air outlet frame 43, which is located at the air outlet end of the second fan 41 to guide the airflow from the second fan 41 to the second air outlet 1c. The air outlet frame 43 has a ventilation opening 43a corresponding to the second air outlet 1c and a mounting opening 43b corresponding to the pull-out opening 1e. The mounting opening 43b is located on the side of the ventilation opening 43a near the third air duct 610. A part of the shelf 5 extends into the second air duct 10b through the mounting opening 43b.

[0073] The structure of the shelf 5 can be customized according to the specific application, as long as it can be used to place items. For example, in Figure 3 and Figure 14 In the example, the shelf 5 includes an operating part 51 and a mating part 52. The mating part 52 is used to hold items and can be formed into a frame structure. The mating part 52 is pulled out and mated with the pull-out opening 1e. The operating part 51 is mated with the pull-out opening 1e and can be used to pull out and assemble the shelf 5. When the shelf 5 is installed, the outer surface of the operating part 51 can be flush with the corresponding outer surface of the housing 1 (for example, the front surface of the operating part 51 is flush with the front surface of the housing 1) so as to ensure the overall performance of the air conditioner 100.

[0074] In some embodiments of the present invention, such as Figures 3-5 As shown, the air duct switching component 6 is located above the second fan 41, which helps to reduce the space occupied by the air conditioner 100 in the horizontal direction. The pull-out port 1e is lower than the second fan 41 so as to ensure that the pull-out port 1e has a height that matches the user's height and is convenient for the user to operate. The second air outlet 1c is lower than the pull-out port 1e, so that the height of the second air outlet 1c is lower, so as to avoid the lower temperature of the indoor space when hot air is blown out from the second air outlet 1c, which helps to improve the uniformity of the indoor ambient temperature.

[0075] In some embodiments of the present invention, such as Figure 7 and Figure 14 As shown, the air conditioner 100 also includes a sterilization component 8, which is disposed inside the housing 1. The sterilization component 8 is used to sterilize the airflow flowing through the second air duct 10b and / or the third air duct 610. The sterilization component 8 is used to sterilize the airflow flowing through the second air duct 10b, or the airflow flowing through the third air duct 610, or the airflow flowing through the second air duct 10b and the third air duct 610, so as to effectively purify the air. The purified airflow can be blown out from the second air outlet 1c to improve the environment and further enrich the functions of the air conditioner 100.

[0076] In some examples, such as Figure 7 and Figure 14As shown, the air conditioner 100 comprises a shelf 5 and a sterilization component 8, the shelf 5 is provided at a pull-out opening 1e of the shell 1 in a pullable manner, the pull-out opening 1e is opposite to the second air duct 10b and is located on the airflow circulation path of the second air duct 10b, the pull-out opening 1e is located on the side of the second air outlet 1c close to the third air duct 610, and the sterilization component 8 is provided in the shell 1 and is used for sterilizing the airflow circulating through the second air duct 10b and / or the third air duct 610. In the airflow direction, the sterilization component 8 can be provided upstream of the shelf 5, so that the airflow first flows through the sterilization component 8 and then flows through the objects on the shelf 5, and the sterilization component 8 can sterilize the objects on the shelf 5.

[0077] It can be understood that when the air conditioner 100 comprises the shelf 5 and the sterilization component 8, the air conditioner 100 can dry and / or sterilize the objects on the shelf 5.

[0078] Optionally, in the example of Figure 7 and Figure 14 , the second ventilation component 4 comprises an air outlet frame 43 provided at the air outlet end of the second air fan 41 to guide the air outlet airflow of the second air fan 41 to the second air outlet 1c, the air outlet frame 43 is formed with a ventilation opening 43a corresponding to the second air outlet 1c and a mounting opening 43b corresponding to the pull-out opening 1e, a part of the shelf 5 extends into the second air duct 10b through the mounting opening 43b, and the sterilization component 8 is mounted on the air outlet frame 43 and located on the upstream side of the mounting opening 43b to sterilize the airflow circulating through the air outlet frame 43.

[0079] Optionally, the sterilization component 8 comprises an ion generator 81 (or a negative ion generator), which releases ions into the second air duct 10b to purify the airflow in the second air duct 10b. The ion generator 81 generates a small amount of ozone while generating a large amount of ions, and the combination of the two is more likely to adsorb various viruses and bacteria, causing changes in their structure or energy transfer, leading to their death.

[0080] Of course, the sterilization component 8 is not limited to this; for example, the sterilization component 8 can comprise at least one of a positive and negative ion generator 81, an ozone generator, an ultraviolet sterilization device (such as an ultraviolet lamp), etc.

[0081] In some embodiments of the present application, the air conditioner 100 further comprises a humidification component provided in the shell 1 and used for humidifying the airflow circulating through the second air duct 10b and / or the third air duct 610 to further enrich the functions of the air conditioner 100.

[0082] The humidifying component can be arranged at the second air outlet 1c, and in the airflow circulation path of the second air duct 10b, the humidifying component is located downstream of the shelf 5, so as to avoid affecting the drying efficiency of the air conditioner 100 on the drying object; for example, the humidifying component is arranged at the second air outlet 1c, and the humidifying component can move between a shielding position and an avoiding position. In the shielding position, the humidifying component is opposite to at least part of the second air outlet 1c, so as to humidify at least part of the airflow at the second air outlet 1c. In the avoiding position, the humidifying component avoids the second air outlet 1c and is opposite to the part of the shell 1 surrounding the second air outlet 1c, so as to stop humidifying.

[0083] In some embodiments of the present application, as shown in Figure 3 and Figure 4 The shell 1 further has an air exhaust port 1d, and the air exhaust port 1d communicates with the second air duct 10b, so that the airflow in the second air duct 10b can also be exhausted through the air exhaust port 1d.

[0084] The air conditioner 100 further comprises an air outlet switching component 9, which switches the air outlet of the second air duct 10b through at least one of the second air outlet 1c and the air exhaust port 1d. The following cases are included: 1. The air outlet switching component 9 switches the second air duct 10b to outlet through the second air outlet 1c, and the air exhaust port 1d does not outlet (as shown in Figure 3 ); 2. The air outlet switching component 9 switches the second air duct 10b to outlet through the air exhaust port 1d, and the second air outlet 1c does not outlet (as shown in Figure 4 ); 3. The air outlet switching component 9 switches the second air duct 10b to outlet through both the second air outlet 1c and the air exhaust port 1d. It can be seen that the air outlet switching component 9 has multiple switching states, so that the second air duct 10b has multiple different air outlet modes, thereby enriching the operation mode of the air conditioner 100, and being beneficial to better meet the actual differentiated needs of the air conditioner 100.

[0085] The air exhaust port 1d can be used to exhaust the airflow to the outdoor and / or the indoor, that is, the airflow at the air exhaust port 1d can be all exhausted to the indoor, or the airflow at the air exhaust port 1d can be all exhausted to the indoor, or part of the airflow at the air exhaust port 1d is exhausted to the outdoor and part of the airflow is exhausted to the indoor.

[0086] It can be understood that when the air outlet 1d is used to exhaust air to the outside, if the air outlet 1d is switched by the air outlet switching component 9, the air flow in the second air duct 10b can be exhausted to the outside through the air outlet 1d, so as to realize the air exchange function of the air conditioner 100, to exhaust the dirty air in the room to the outside, and the outdoor fresh air can be supplemented to the room through other positions in the whole environment, so as to ensure that the indoor air is fresh and healthy, and the air conditioner 100 has a fresh air function to a certain extent, so that a separate fresh air system is not needed, which is beneficial to simplify the structure of the air conditioner 100, save the internal space of the shell 1, and reduce the cost; when the air outlet 1d is used to exhaust air to the indoor, if the air outlet 1d is switched by the air outlet switching component 9, the air flow in the second air duct 10b can be exhausted to the indoor through the air outlet 1d, so as to improve the circulation of the indoor air; when the air outlet 1d is used to exhaust air to the indoor and the outdoor, if the air outlet 1d is switched by the air outlet switching component 9, the air exchange and the improvement of the indoor air circulation can be realized at the same time. In the following description, the air outlet 1d is used to exhaust air to the outdoor, and the heater 64 is not operated as an example, and those skilled in the art can easily understand other technical solutions after reading the following technical solutions.

[0087] It can be seen that by switching the switching state of the air outlet switching component 9 and the air duct switching component 6, the air conditioner 100 can have at least the following multiple operating modes:

[0088] 1. The air outlet switching component 9 switches the second air duct 10b to exhaust air through the second air outlet 1c, and the air outlet 1d does not exhaust air, and the air duct switching component 6 is switched to the first switching state, and the air conditioner 100 realizes air outlet through the first air outlet 1b and the second air outlet 1c. When the air conditioner 100 is used for refrigeration or heating, the air flow in the first air duct 10a exchanges heat with the heat exchange component 2, and part of the air flow after heat exchange is blown out through the first air outlet 1b, and the other part of the air flow after heat exchange flows to the second air duct 10b and is blown out through the second air outlet 1c, so as to quickly adjust the environment temperature.

[0089] 2. The air outlet switching component 9 switches the second air duct 10b to exhaust air through the second air outlet 1c, and the air outlet 1d does not exhaust air, and the air duct switching component 6 is switched to the second switching state, and the air conditioner 100 realizes air outlet through the first air outlet 1b and the second air outlet 1c. When the air conditioner 100 is used for refrigeration or heating, the air flow in the first air duct 10a exchanges heat with the heat exchange component 2, and the air flow after heat exchange is blown out through the first air outlet 1b to adjust the environment temperature, and the air flow in the second air duct 10b does not exchange heat with the heat exchange component 2, so that the air flow blown out from the second air outlet 1c can be used for the circulation of the indoor air, and the circulation of the indoor air is improved.

[0090] 3、outlet switching component 9 switches the second air duct 10b to exit through the exhaust outlet Id, and the second outlet 1c does not blow air, while the air duct switching component 6 switches to the first switching state, the air conditioner 100 blows air through the first outlet 1b and exhausts air through the exhaust outlet Id. When the air conditioner 100 is used for cooling or heating, the airflow in the first air duct 10a exchanges heat with the heat exchange component 2, and then part of the airflow after heat exchange is blown out through the first outlet 1b to adjust the ambient temperature, and the other part of the airflow after heat exchange flows to the second air duct 10b and is blown out through the exhaust outlet Id to achieve air exchange.

[0091] 4、outlet switching component 9 switches the second air duct 10b to exit through the exhaust outlet Id, and the second outlet 1c does not blow air, while the air duct switching component 6 switches to the second switching state, the air conditioner 100 blows air through the first outlet 1b and exhausts air through the exhaust outlet Id. When the air conditioner 100 is used for cooling or heating, the airflow in the first air duct 10a exchanges heat with the heat exchange component 2, and then part of the airflow after heat exchange is blown out through the first outlet 1b to adjust the ambient temperature, and the other part of the airflow after heat exchange flows to the second air duct 10b and is blown out through the exhaust outlet Id to achieve air exchange.

[0092] 5、outlet switching component 9 switches the second air duct 10b to exit through the second outlet 1c and the exhaust outlet Id, while the air duct switching component 6 switches to the first switching state, the air conditioner 100 blows air through the first outlet 1b and the second outlet 1c, and exhausts air through the exhaust outlet Id. When the air conditioner 100 is used for cooling or heating, the airflow in the first air duct 10a exchanges heat with the heat exchange component 2, and then part of the airflow after heat exchange is blown out through the first outlet 1b, part of the airflow after heat exchange flows to the second air duct 10b and is blown out through the second outlet 1c to facilitate rapid adjustment of the ambient temperature, and the other part of the airflow after heat exchange flows to the second air duct 10b and is blown out through the exhaust outlet Id to achieve air exchange.

[0093] 6、outlet switching component 9 switches the second air duct 10b to exit through the second outlet 1c and the exhaust outlet Id, while the air duct switching component 6 switches to the second switching state, the air conditioner 100 blows air through the first outlet 1b and the second outlet 1c, and exhausts air through the exhaust outlet Id. When the air conditioner 100 is used for cooling or heating, the airflow in the first air duct 10a exchanges heat with the heat exchange component 2, and then part of the airflow after heat exchange is blown out through the first outlet 1b to adjust the ambient temperature, and the other part of the airflow after heat exchange flows to the second air duct 10b and is blown out through the exhaust outlet Id to achieve air exchange.

[0094] Therefore, the second air duct 10b can have multiple functions of air conditioner air outlet air duct and air conditioner exhaust air duct, which is convenient to realize "one thing with multiple uses", is conducive to reducing the number of components of the air conditioner 100, simplifying the structure of the air conditioner 100, and reducing the cost.

[0095] Optionally, the air outlet switching component 9 comprises a first switch valve 91 and a second switch valve 92, the first switch valve 91 is arranged at the second air outlet 1c, and the first switch valve 91 is used to open or close the second air outlet 1c, the second switch valve 92 is arranged at the exhaust air outlet 1d, and the second switch valve 92 is used to open or close the exhaust air outlet 1d.

[0096] It can be seen that when the first switch valve 91 opens the second air outlet 1c and the second switch valve 92 closes the exhaust air outlet 1d, the air outlet switching component 9 switches the second air duct 10b to blow air through the second air outlet 1c; when the first switch valve 91 closes the second air outlet 1c and the second switch valve 92 opens the exhaust air outlet 1d, the air outlet switching component 9 switches the second air duct 10b to blow air through the exhaust air outlet 1d; when the first switch valve 91 opens the second air outlet 1c and the second switch valve 92 opens the exhaust air outlet 1d, the air outlet switching component 9 switches the second air duct 10b to blow air through the second air outlet 1c and the exhaust air outlet 1d respectively. Of course, when the air conditioner 100 is stopped, the first switch valve 91 can close the second air outlet 1c, and the second switch valve 92 can close the exhaust air outlet 1d, which is conducive to avoiding that the external dust and the like enters the second air duct 10b through the second air outlet 1c and the exhaust air outlet 1d, and is convenient to ensure the cleanliness of the air conditioner 100.

[0097] Therefore, by controlling the first switch valve 91 and the second switch valve 92, it is convenient to realize the switching control of the air outlet switching component 9, and the logic is simple and easy to realize.

[0098] Optionally, the first switch valve 91 is also used to adjust the air outlet direction of the second air outlet 1c, for example, the first switch valve 91 is formed as a deflector or a switch door, etc., and the air outlet direction of the second air outlet 1c is changed by the movement of the first switch valve 91, which is conducive to further expanding the air supply range of the air conditioner 100 to a certain extent, and is convenient to make the entire indoor air form a large range of circulation, and improve the circulation of the indoor air.

[0099] Of course, the structure of the air outlet switching component 9 is not limited to this; for example, the air outlet switching component 9 can also be configured to comprise a switching valve, the switching valve is movable relative to the shell 1, and the switching valve is used to switch at least one of the second air outlet 1c and the exhaust air outlet 1d to be opened, the switching valve can have a first switching position, a second switching position and a third switching position, in the first switching position, the switching valve opens the second air outlet 1c and closes the exhaust air outlet 1d, in the second switching position, the switching valve opens the exhaust air outlet 1d and closes the second air outlet 1c, and in the third switching position, the switching valve opens the second air outlet 1c and the exhaust air outlet 1d.

[0100] In some embodiments of the present application, as shown in Figures 6-9 The air duct switching component 6 comprises a moving piece 61 which is movable relative to the housing 1, a third air duct 610 is formed in the moving piece 61, and a heater 64 is arranged in the moving piece 61 to heat the air flow passing through the third air duct 610. The moving piece 61 is formed with an air duct inlet 61a and an air duct outlet 61b which are in communication with the third air duct 610, and the air duct outlet 61b is always in communication with the second air duct 10b, that is, no matter where the moving piece 61 moves to, the air duct outlet 61b remains in communication with the second air duct 10b. The moving piece 61 is reciprocally movable between a first position and a second position. In the first position, the air duct inlet 61a is in communication with the first air duct 10a, and the air duct inlet 61a is blocked with the air inlet 1a, at this time, the second air duct 10b is in communication with the first air duct 10a through the third air duct 610. In the second position, the air duct inlet 61a is in communication with the air inlet 1a, and the air duct inlet 61a is blocked with the first air duct 10a, at this time, the second air duct 10b is in communication with the air inlet 1a through the third air duct 610. Thus, the switching of the air duct switching component 6 between the first switching state and the second switching state is realized by the movement of the moving piece 61.

[0101] It can be understood that in the first switching state, the air duct switching component 6 communicates the second air duct 10b and the first air duct 10a, and blocks the second air duct 10b and the air inlet 1a, so that the second air duct 10b is not in communication with the air inlet 1a. In the second switching state, the air duct switching component 6 communicates the second air duct 10b and the air inlet 1a, and blocks the second air duct 10b and the first air duct 10a, so that the second air duct 10b is not in communication with the first air duct 10a.

[0102] As shown in Figure 8 The air duct switching component 6 further comprises a driving assembly 62 which drives the moving piece 61 to reciprocally move between the first position and the second position, so as to realize the switching of the moving piece 61 by controlling the driving assembly 62, and improve the switching convenience of the moving piece 61 between the first position and the second position. In addition, compared with manually controlling the moving piece 61, the moving piece 61 does not need to be provided with a control part extending out of the housing 1, so as to ensure the sealing of the second air duct 10b and avoid air leakage of the second air duct 10b.

[0103] In some embodiments of the present application, as shown in Figures 10-13As shown, the heater 64 is fixed to the moving member 61 to move synchronously with the moving member 61, facilitating the installation of the heater 64, and the heater 64 does not interfere with the communication state of the third air duct 610, to ensure that the air duct switching member 6 effectively switches to the first switching state or the second switching state, and no matter which position the moving member 61 moves to, the heater 64 can be used to heat the airflow passing through the third air duct 610.

[0104] In some embodiments of the present application, as shown in Figures 10-13 As shown, the moving member 61 includes a cylindrical portion 611, the inner cavity of the cylindrical portion 611 defines the third air duct 610, the air duct inlet 61a is formed on the peripheral wall surface of the cylindrical portion 611, one axial end of the cylindrical portion 611 is a closed end F1, the other axial end of the cylindrical portion 611 is an open end F2, the open end F2 is configured as the air duct outlet 61b, and the driving assembly 62 drives the moving member 61 to reciprocate along the axial direction of the cylindrical portion 611.

[0105] As shown in Figure 9 As shown, the heater 64 includes a plurality of heating rings 641 arranged along the axial direction of the cylindrical portion 611, each heating ring 641 respectively heats the airflow passing therethrough, to facilitate the heater 64 to have sufficient heating area and heating efficiency, and the heating ring 641 can be arranged adjacent to the inner cavity of the cylindrical portion 611, facilitating the fixed connection of the heating ring 641 and the moving member 61.

[0106] It should be noted that the heating ring 641 can be extended as a closed ring or an open ring, and the central axis of the heating ring 641 can be parallel to or coincide with the central axis of the cylindrical portion 611. The "ring" should be understood in a broad sense, including but not limited to a circular ring, a polygonal ring. Of course, the structure of the heater 64 is not limited to this.

[0107] It can be understood that the moving member 61 can be arranged at the junction of the first air duct 10a and the second air duct 10b, in the first position, the air duct inlets 61a are all located in the first air duct 10a, so that the airflow in the second air duct 10b can flow to the third air duct 610 through the air duct inlets 61a, and then flow to the second air duct 10b through the air duct outlets 61b, so that the air duct switching member 6 switches to the first switching state, in the second position, the air duct inlets 61a are all located in the second air duct 10b, at this time the air duct inlets 61a can be formed as "airflow inlets" of the second air duct 10b, the airflow at the air inlet 1a can flow to the third air duct 610 through the air duct inlets 61a, and then flow to the second air duct 10b through the air duct outlets 61b, so that the air duct switching member 6 switches to the second switching state.

[0108] It should be noted that in the description in the present application, "cylindrical" should be understood in a broad sense, for example, it can be a circular cylinder, a polygonal cylinder, etc.

[0109] Of course, the arrangement of the moving part 61 is not limited to this; for example, a third air duct 610 is defined in the moving part 61, and the top of the moving part 61 has a first air vent and a second air vent respectively communicating with the third air duct 610, in the first position, the first air vent communicates with the first air duct 10a, and the second air vent blocks the air inlet 1a, in the second position, the second air vent communicates with the air inlet 1a, and the first air vent blocks the first air duct 10a.

[0110] In some embodiments of the present application, as shown in Figures 9-13 The air duct switching component 6 further includes a fixed part 63, the fixed part 63 has a through hole 63a formed therein, the cylindrical part 611 passes through the through hole 63a, and the axial length of the cylindrical part 611 is greater than the axial length of the through hole 63a, so that during the movement of the moving part 61, there is always a part of the cylindrical part 611 protruding out of the through hole 63a. The closed end F1 is surrounded by a first sealing ring 613, which can be arranged on the outer periphery of the closed end F1 and extend radially outward along the cylindrical part 611, and the open end F2 is surrounded by a second sealing ring 614, which can be arranged on the outer periphery of the open end F2 and extend radially outward along the cylindrical part 611, so as to facilitate ensuring that the first sealing ring 613 and the second sealing ring 614 are always located outside the through hole 63a during the entire movement of the moving part 61.

[0111] As shown in Figures 10-13 The end of the through hole 63a close to the first sealing ring 613 is a first end F3, in the first position, the first sealing ring 613 is spaced apart from the first end F3 to form a first communication port 6a communicating with the first air duct 10a, and part of the air duct inlet 61a is exposed to the first communication port 6a to communicate with the first air duct 10a, that is, the cylindrical part 611 having the part of the air duct inlet 61a protrudes out of the through hole 63a towards the side where the first air duct 10a is located, so that the above-mentioned part of the air duct inlet 61a communicates with the first air duct 10a through the first communication port 6a; in the second position, the first sealing ring 613 covers the first end F3 to close the first communication port 6a, at this time, the cylindrical part 611 having the above-mentioned part of the air duct inlet 61a is retracted into the through hole 63a, and the first sealing ring 613 cooperates with the first end F3 to separate the air duct inlet 61a from the second air duct 10b.

[0112] The second end F4 of the through hole 63a is close to the second sealing ring 614. In the second position, the second sealing ring 614 is spaced from the second end F4 to form a second communication port 6b in communication with the air inlet 1a, and a part of the air duct inlet 61a is exposed to the second communication port 6b to communicate with the air inlet 1a, that is, the cylindrical part 611 forming the part of the air duct inlet 61a protrudes into the through hole 63a towards the side where the second air duct 10b is located, so that the part of the air duct inlet 61a communicates with the air inlet 1a through the second communication port 6b; in the first position, the second sealing ring 614 covers the second end F4 to close the second communication port 6b, at this time, the cylindrical part 611 forming the part of the air duct inlet 61a is retracted into the through hole 63a, and the second sealing ring 614 cooperates with the second end F4 to separate the air duct inlet 61a from the air inlet 1a.

[0113] Thus, by setting the fixed part 63 and cooperating with the moving part 61, the effective switching of the air duct switching part 6 is ensured.

[0114] For example, in the example of Figures 10-13 , the cylindrical part 611 moves in the up-down direction, the first sealing ring 613 is located above the second sealing ring 614, the cylindrical part 611 moves upwards until the second sealing ring 614 abuts against the second end F4 to cover the second end F4, at this time, the moving part 61 is in the first position, the first sealing ring 613 is spaced above the first end F3, and the upper part of the air duct inlet 61a protrudes out of the through hole 63a to make the upper part of the air duct inlet 61a communicate with the first air duct 10a through the first communication port 6a between the first sealing ring 613 and the first end F3, and the lower part of the air duct inlet 61a is located in the through hole 63a, then the second sealing ring 614 cooperates with the second end F4 to separate the entire air duct inlet 61a from the air inlet 1a; the cylindrical part 611 moves downwards until the first sealing ring 613 abuts against the first section to cover the first section, at this time, the moving part 61 is in the second position, the second sealing ring 614 is spaced below the second end F4, and the lower part of the air duct inlet 61a protrudes out of the through hole 63a to make the lower part of the air duct inlet 61a communicate with the air inlet 1a through the second communication port 6b between the second sealing ring 614 and the second end F4, and the upper part of the air duct inlet 61a is located in the through hole 63a, then the first sealing ring 613 cooperates with the first end F3 to separate the entire air duct inlet 61a from the first air duct 10a.

[0115] Optionally, the entire circumferential wall surface of the cylindrical part 611 has a grid structure, and the grid structure defines the air duct inlet 61a. Of course, a plurality of ventilation holes can also be formed on the circumferential wall surface of the cylindrical part 611 to define the air duct inlet 61a.

[0116] In some embodiments of the present application, as Figure 12 and Figure 13As shown, the second ventilation component 4 comprises a fan shell 42, the second fan 41 is arranged in the fan shell 42, the fan shell 42 is provided with an air inlet end 42a, and the side of the second sealing ring 614 away from the cylindrical portion 611 is further provided with a sleeve portion 612. During the movement of the moving element 61, the sleeve portion 612 is always sleeved with the air inlet end 42a from the inside and outside, so that the air duct outlet 61b is always in communication with the inner cavity of the fan shell 42. During the movement of the moving element 61, the sleeve portion 612 reciprocates relative to the air inlet end 42a, and the sleeve portion 612 is always not separated from the air inlet end 42a, and the air duct outlet 61b is always in communication with the second air duct 10b. The communication mode of the air duct outlet 61b with the second air duct 10b is simple and easy to realize, and the air inlet end 42a has a certain guiding effect on the movement of the sleeve portion 612.

[0117] For example, in the example of Figures 5-8 , the air inlet end 42a is in a cylindrical structure, and the air inlet end 42a can be sleeved outside the sleeve portion 612. The driving assembly 62 comprises a driving mechanism 621 and a motor 622. The driving mechanism 621 is connected to the second sealing ring 614 and arranged on the outside of the air inlet end 42a. The driving mechanism 621 (for example, the rack 6212 described below) and the sleeve portion 612 can jointly define a matching groove. The air inlet end 42a is inserted into the matching groove, which is beneficial to further improve the guiding effect of the air inlet end 42a on the movement of the moving element 61, ensure the smooth movement of the moving element 61, and the motor 622 is installed on the fan shell 42 to drive the sleeve portion 612 to move relative to the fan shell 42 through the driving mechanism 621. Of course, the air inlet end 42a can also be arranged in the sleeve portion 612.

[0118] Optionally, in the example of Figure 13 , when the moving element 61 is in the second position, the air inlet end 42a can abut against the wall surface of the matching groove to limit the continuous movement of the moving element 61. At this time, the air inlet end 42a and the first end F3 both exert a certain force on the moving element 61 to bear the moving element 61, which is beneficial to improve the stress of the driving assembly 62.

[0119] Optionally, in the example of Figure 5 and Figure 14 , the second ventilation component 4 further comprises an air outlet frame 43 which is fixedly arranged on the air outlet end of the fan shell 42 to guide the air flow of the fan shell 42 to the second air outlet 1c. The air outlet frame 43 is formed with a ventilation opening corresponding to the second air outlet 1c. Of course, the air conditioner 100 of the present application can also not be provided with the air outlet frame 43, and the air flow path between the fan shell 42 and the second air outlet 1c is defined by the shell 1.

[0120] In some embodiments of the present application, as Figures 5-7As shown, the heat exchange component 2 is located above the air duct switching component 6, the moving part 61 moves vertically, the fixed part 63 defines a water collecting groove 63b around the through hole 63a, the water collecting groove 63b can be formed as an annular groove, the water collecting groove 63b is arranged opposite to the heat exchange component 2, and then at least part of the orthographic projection of the heat exchange component 2 can be located in the range of the orthographic projection of the water collecting groove 63b in the up-down direction, so that the water collecting groove 63b can be used to collect the condensed water on the heat exchange component 2, facilitating the collection and discharge of the condensed water, and meanwhile, since the through hole 63a has a certain axial length, the outer wall surface of the circumferential wall of the through hole 63a can participate in the definition of the water collecting groove 63b, avoiding that the water in the water collecting groove 63b flows to other positions through the through hole 63a, and facilitating the guarantee of the internal cleanliness of the air conditioner 100. The fixed part 63 can be directly or indirectly fixed to the heat exchange component 2.

[0121] In addition, since the water collecting groove 63b is annular, it is convenient to make the water collecting groove 63b applicable to heat exchange components 2 of different structures, for example, the heat exchange component 2 is formed as a cylindrical shape, or a C shape, or includes two sub-heat exchangers arranged side by side, and the like, which is beneficial to improve the applicability of the fixed part 63.

[0122] In some optional embodiments of the present application, as shown in the drawings, Figure 8 As shown, the driving assembly 62 includes a driving mechanism 621 and a motor 622, the motor 622 drives the moving part 61 to move linearly through the driving mechanism 621, the moving mode of the moving part 61 is simple, which is convenient to simplify the structure of the driving mechanism 621, reduce the cost, and facilitate to reduce the space occupied by the moving part 61 during the whole movement process, so as to make more arrangement space for other components in the shell 1.

[0123] Optionally, as shown in the drawings, Figure 8 As shown, the driving mechanism 621 includes a gear 6211 and a rack 6212, the motor 622 is connected with the gear 6211, the gear 6211 is engaged with the rack 6212, the gear 6211 rotates to drive the rack 6212 to move linearly, so as to realize the movement of the moving part 61, the driving mechanism 621 has simple structure and good driving bearing performance, which is convenient to ensure the smooth movement of the moving part 61. The rack 6212 is integrally formed on the moving part 61, which can save the assembly process of the rack 6212 and the moving part 61, and facilitate the machining of the rack 6212 and the moving part 61.

[0124] Of course, the rack 6212 can also be fixedly connected to the moving part 61 through assembly means. The structure of the driving mechanism 621 is not limited to this; for example, the driving mechanism 621 can also be configured to include a lead screw and a nut, the lead screw is connected with the motor 622 to be driven to rotate by the motor 622, the lead screw is threadedly matched with the nut, and the nut is fixedly arranged on the moving part 61, so that the nut drives the moving part 61 to move linearly.

[0125] Optionally, in Figures 6-8 the example, the rack 6212 and the sleeve part 612 can jointly define a matching groove, the air inlet end 42a is inserted into the matching groove, the tooth structure of the rack 6212 is arranged on the side of the rack 6212 away from the sleeve part 612, and then the gear 6211 is matched to the end of the rack 6212 away from the air inlet end 42a, so as to avoid interference between the gear 6211 and the air inlet end 42a.

[0126] Optionally, the driving assembly 62 can be multiple, and the multiple driving assemblies 62 can be arranged at intervals along the circumference of the third air duct 610, so as to ensure smooth movement of the moving part 61. Figure 8 In the example, the driving assembly 62 is two, and the two driving assemblies 62 are arranged in a diametrically opposite manner along the third air duct 610. Of course, the driving assembly 62 can be three or more.

[0127] In some embodiments of the present application, as shown in Figure 3 and Figure 4 , the first air duct 10a is located above the second air duct 10b, the air duct switching part 6 is located between the first air duct 10a and the second air duct 10b, so that the air duct switching part 6 realizes the communication or blocking of the second air duct 10b and the first air duct 10a, and the first air outlet 1b is higher than the second air outlet 1c, which is beneficial to expand the air supply range of the air conditioner 100 in the up-down direction. When the air conditioner 100 is used for heating, the air duct switching part 6 can be switched to the first switching state, so that the first air outlet 1b and the second air outlet 1c blow out hot air, and the second air outlet 1c is arranged at a lower position, which is beneficial to realize the carpet air supply of the air conditioner 100, especially when the air conditioner 100 is a cabinet type air conditioner. The air conditioner 100 effectively avoids the situation that the temperature difference between the upper and lower layers of the indoor space is large and the temperature of the lower layer is low, which causes the user to feel cold in the feet, and improves the thermal comfort of the user.

[0128] It should be noted that the first air outlet 1b is higher than the second air outlet 1c, which means that the first air outlet 1b is directly above or obliquely above the second air outlet 1c, or only means that the position of the first air outlet 1b is higher than that of the second air outlet 1c in the up-down direction. For example, in Figure 5 the example, the first air outlet 1b and the second air outlet 1c are both formed on the front side of the shell 1, and the first air outlet 1b is directly above the second air outlet 1c.

[0129] Further, in Figures 1-4In the example shown in FIG. 1, the first air outlet 1b is arranged adjacent to the top of the shell 1, and the second air outlet 1c is arranged adjacent to the bottom of the shell 1, so that the distance between the first air outlet 1b and the second air outlet 1c in the up-down direction is relatively large, which is conducive to reducing the overlapping area of the air outlet area corresponding to the first air outlet 1b and the air outlet area corresponding to the second air outlet 1c when the first air outlet 1b and the second air outlet 1c are both blowing air, so as to further expand the air supply range of the air conditioner 100, and at the same time, it is also conducive to further avoiding the lower part of the indoor space being too cold, so as to improve the uniformity of the indoor environment temperature.

[0130] Optionally, the opening area of the first air outlet 1b is larger than the opening area of the second air outlet 1c.

[0131] In some embodiments of the present application, as shown in Figure 3 and Figure 4 , the first fan 31 is arranged above the heat exchange component 2, and the air duct switching component 6 can be connected to the lower end of the heat exchange component 2 to participate in the division of the internal space of the shell 1 into the first air duct 10a and the second air duct 10b, which is conducive to reducing the horizontal space occupied by the air conditioner 100, and the first air outlet 1b is higher than the first fan 31, so that in the airflow direction in the first air duct 10a, the first fan 31 is arranged on the downstream side of the heat exchange component 2, and the airflow flowing from the air inlet 1a into the first air duct 10a first flows through the heat exchange component 2, then flows through the first fan 31, and finally is blown out through the first air outlet 1b. Among them, at least part of the air inlet 1a is opposite to the heat exchange component 2, and the whole air inlet 1a is opposite to the heat exchange component 2, or part of the air inlet 1a is opposite to the heat exchange component 2, so as to ensure the communication between the air inlet 1a and the first air duct 10a, and to ensure the heat exchange area of the airflow flowing into the first air duct 10a, and at the same time, it is also convenient to ensure the switching communication between the air inlet 1a and the second air duct 10b,

[0132] Optionally, the first fan 31 is an axial fan, which is conducive to simplifying the structure of the first air duct 10a. Of course, the type of the first fan 31 is not limited to this, for example, it can also be a cross-flow fan or the like.

[0133] Optionally, the second fan 41 is an axial fan, which is conducive to simplifying the structure of the second air duct 10b. Of course, the type of the second fan 41 is not limited to this, for example, it can also be a cross-flow fan or the like.

[0134] Optionally, in Figure 3 and Figure 4In the example, a portion of the air inlet 1a is horizontally opposite to the heat exchange component 2, and another portion of the air inlet 1a is horizontally opposite to the air duct switching component 6. For example, the air inlet 1a is located at the junction of the first air duct 10a and the second air duct 10b, which facilitates the air duct switching component 6 to connect or block the second air duct 10b and the air inlet 1a. If the second air duct 10b is connected to the first air duct 10a, the airflow in the first air duct 10a can flow to the second air duct 10b through the air duct switching component 6. If the second air duct 10b is connected to the air inlet 1a, the airflow at the other portion of the air inlet 1a can flow directly into the second air duct 10b. Of course, when the entire air inlet 1a is opposite to the heat exchange component 2, if the second air duct 10b is connected to the air inlet 1a, a portion of the airflow flowing through the air inlet 1a to the area between the air inlet 1a and the heat exchange component 2 can flow into the second air duct 10b.

[0135] In some embodiments of the present invention, such as Figure 5 As shown, the heat exchange component 2 is formed into a cylindrical structure to ensure the heat exchange area, and the air inlet 1a is located on the radial outer side of the heat exchange component 2. Of course, the heat exchange component 2 can also be formed into other shapes, such as U-shaped, or V-shaped, or include two sub-heat exchangers arranged side by side.

[0136] Among them, there are one or more air inlets 1a, and the air inlets 1a can extend circumferentially along the heat exchange component 2; in Figure 2 and Figure 5 In the example, there are two air inlets 1a, which are arranged opposite each other along the radial direction of the heat exchange component 2; of course, there can also be three or more air inlets 1a.

[0137] like Figure 5 As shown, the housing 1 may include a front panel 11, an outer casing 12, a top cover 13, and a chassis 14. The front panel 11 covers the front side of the outer casing 12, the top cover 13 covers the top of the outer casing 12, and the chassis 14 covers the bottom of the outer casing 12. The first air outlet 1b and the second air outlet 1c are both formed on the front panel 11, and the air inlet 1a is formed on the outer casing 12.

[0138] Optionally, in Figure 3 and Figure 4 In the example, a guide plate 7 that can move relative to the housing 1 is provided at the first air outlet 1b. The guide plate 7 is used to adjust the air outlet direction of the first air outlet 1b and / or to open and close the first air outlet 1b.
