[0047] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0048] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0049] Hereinafter, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.

[0050] The air conditioner 100 can be a cabinet air conditioner, a wall-mounted air conditioner, etc. Of course, the air conditioner 100 can also be an integrated air conditioner (such as a window air conditioner, a portable air conditioner, etc.) or a split-type air conditioner. In the following description of this application, a cabinet air conditioner is used as an example for illustration. After reading the following technical solution, those skilled in the art will easily understand that the air conditioner 100 can be a technical solution for other types of air conditioners.

[0051] like Figures 1-4As shown, the air conditioner 100 includes a housing 1, which has a first air duct 10a and a second air duct 10b. The housing 1 has an air inlet 1a, a first air outlet 1b, a second air outlet 1c, and an exhaust outlet 1d. The air inlet 1a and the first air outlet 1b are both connected to the first air duct 10a, and the second air outlet 1c and the exhaust outlet 1d are both connected to the second air duct 10b. Air outside the housing 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 achieve air outlet of the air conditioner 100. Air flowing into the second air duct 10b can be blown out through the second air outlet 1c to achieve air outlet of the air conditioner 100. Of course, air flowing into the second air duct 10b can also be discharged through the exhaust outlet 1d.

[0052] The air conditioner 100 also includes a heat exchange component 2, which is located in the first air duct 10a. The air flowing through the first air duct 10a can exchange heat with the heat exchange component 2 to regulate the ambient temperature.

[0053] The air conditioner 100 also includes a first ventilation component 3 and a second ventilation component 4. The first ventilation component 3 includes a first fan 31 disposed in the first air duct 10a. 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 drive the air in the first air duct 10a to flow toward the first air outlet 1b. The second ventilation component 4 includes a second fan 41 disposed in the second air duct 10b. The second fan 41 operates to drive the air flow in the second air duct 10b to flow toward the second air outlet 1c and the exhaust vent 1d.

[0054] The operation control of the first fan 31 and the second fan 41 can be specifically configured according to the actual application. For example, the first fan 31 and the second fan 41 can be configured such that both the first fan 31 and the second fan 41 operate when the air conditioner 100 is running. That is, regardless of the state, as long as the air conditioner 100 is turned on, both the first fan 31 and the second fan 41 will operate. Alternatively, the first fan 31 and the second fan 41 can be configured such that at least one of the first fan 31 and the second fan 41 operates when the air conditioner 100 is running. That is, regardless of the state, as long as the air conditioner 100 is turned on, at least one of the first fan 31 and the second fan 41 will operate. Unit 41 can be configured such that when the air conditioner 100 is running, the first fan 31 operates, and the second fan 41 can be freely switched. That is, regardless of the state, as long as the air conditioner 100 is turned on, the first fan 31 operates, while the second fan 41 can only operate when the corresponding function is turned on; or, the first fan 31 and the second fan 41 can also be configured such that when the air conditioner 100 is running, the second fan 41 operates, and the first fan 31 can be freely switched. That is, regardless of the state, as long as the air conditioner 100 is turned on, the second fan 41 operates, while the first fan 31 can only operate when the corresponding function is turned on.

[0055] In the following description, the example of both the first fan 31 and the second fan 41 operating is used. After reading the following technical solution, those skilled in the art can easily understand the technical solutions for other operating modes of the first fan 31 and the second fan 41.

[0056] The air conditioner 100 also includes an air outlet switching component 5. The air outlet switching component 5 switches the second air duct 10b to discharge air through at least one of the second air outlet 1c and the exhaust outlet 1d, including the following situations: 1. The air outlet switching component 5 switches the second air duct 10b to discharge air through the second air outlet 1c, and the exhaust outlet 1d does not discharge air (e.g., ...). Figure 3 (as shown); 2. The air outlet switching component 5 switches the second air duct 10b to the exhaust port 1d outlet, and the second air outlet 1c does not produce air (as shown). Figure 4 (As shown); 3. The air outlet switching component 5 switches the second air duct 10b to discharge air through both the second air outlet 1c and the exhaust outlet 1d. It can be seen that the air outlet switching component 5 has multiple switching states, so that the second air duct 10b has multiple different air discharge modes, thereby enriching the operation mode of the air conditioner 100 and helping the air conditioner 100 to better meet actual differentiated needs.

[0057] Among them, the exhaust vent 1d can be used to exhaust airflow to the outside and / or the inside, that is, the airflow at the exhaust vent 1d can be completely exhausted to the inside, or the airflow at the exhaust vent 1d can be completely exhausted to the inside, or part of the airflow at the exhaust vent 1d can be exhausted to the outside and part of it can be exhausted to the inside.

[0058] Understandably, when exhaust vent 1d is used to exhaust airflow to the outside, if the air outlet switching component 5 switches the exhaust vent 1d to exhaust air, the airflow in the second duct 10b can be exhausted to the outside through exhaust vent 1d, thus enabling the air conditioner 100 to perform its ventilation function, exhausting the indoor polluted air to the outside, and allowing fresh outdoor air to be replenished to the room from other parts of the environment, ensuring fresh and healthy indoor air. In this case, the air conditioner 100 has a certain degree of fresh air function, eliminating the need for a separate fresh air system, which simplifies the structure of the air conditioner 100, saves internal space in the casing 1, and reduces costs. When exhaust vent 1d is used to exhaust airflow to the inside, if the air outlet switching component 5 switches the exhaust vent 1d to exhaust air, the airflow in the second duct 10b can be exhausted to the room through exhaust vent 1d, thus improving the circulation of indoor air. When exhaust vent 1d is used to exhaust airflow to both the inside and outside, if the air outlet switching component 5 switches the exhaust vent 1d to exhaust air, ventilation can be achieved while improving indoor air circulation. In the following description, the use of exhaust vent 1d to exhaust airflow to the outside is taken as an example. After reading the following technical solution, those skilled in the art will easily understand the technical solution of exhaust vent 1d exhausting airflow to the room, and the technical solution of exhaust vent 1d exhausting airflow to both the room and the outside.

[0059] The air conditioner 100 also includes an air duct switching component 6, which has a first switching state and a second switching state, and can switch between the first switching state and the second switching state. In the first switching state (e.g., Figure 3 As shown), the air duct switching component 6 connects the second air duct 10b and the first air duct 10a, and the air duct switching component 6 blocks the second air duct 10b from the air inlet 1a, so that the second air duct 10b and the air inlet 1a are not connected. At this time, the airflow at the air inlet 1a cannot flow directly into the second air duct 10b. However, since the air inlet 1a is connected to the first air duct 10a, the airflow at the air inlet 1a flows into the first air duct 10a. A part of the airflow in the first air duct 10a can be blown out through the first air outlet 1b, and another part of the airflow in the first air duct 10a can flow into the second air duct 10b. In the second switching state (e.g. Figure 4 As shown, the air duct switching component 6 connects the second air duct 10b and the air inlet 1a, and the air duct switching component 6 blocks the second air duct 10b from the first air duct 10a, so that the second air duct 10b and the first air duct 10a are not connected. At this time, the airflow at the air inlet 1a can flow directly into the first air duct 10a and the second air duct 10b respectively, and the airflow in the first air duct 10a can be blown out through the first air outlet 1b.

[0060] As can be seen, by switching the switching states of the air outlet switching component 5 and the air duct switching component 6, the air conditioner 100 can have at least the following multiple operating modes:

[0061] 1. The air outlet switching component 5 switches the second air duct 10b to outlet air through the second air outlet 1c, and the exhaust outlet 1d does not outlet air. Meanwhile, the air duct switching component 6 switches to the first switching state. At this time, the airflow at the air inlet 1a flows directly into the first air duct 10a and cannot flow directly into the second air duct 10b. A portion of the airflow in the first air duct 10a can be blown out through the first air outlet 1b, and another portion of the airflow in the first air duct 10a can flow into the second air duct 10b and be blown out through the second air outlet 1c. Obviously, in this operating state, the air conditioner 100 outlets air through the first air outlet 1b and the second air outlet 1c.

[0062] In the first switching state, the air duct switching component 6 allows the second air duct 10b to be connected to the downstream side of the heat exchange component 2. That is, the second air duct 10b is connected to the portion of the first air duct 10a located downstream of the heat exchange component 2. 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. A portion of the heat-exchanged airflow is then blown out through the first air outlet 1b, and another portion flows to the second air duct 10b and is blown out through the second air outlet 1c, thus facilitating rapid adjustment of the ambient temperature. Of course, the configuration of the air conditioner 100 is not limited to this; for example, the air conditioner 100 can also be used solely for air supply.

[0063] 2. The air outlet switching component 5 switches the second air duct 10b to discharge air through the second air outlet 1c, and the exhaust outlet 1d does not discharge air. Meanwhile, the air duct switching component 6 switches to the second switching state. At this time, part of the airflow at the air inlet 1a flows directly to the first air duct 10a, and another part flows directly into the second air duct 10b. The airflow in the first air duct 10a can be blown out through the first air outlet 1b, and the airflow in the second air duct 10b can be blown out through the second air outlet 1c. The first air duct 10a and the second air duct 10b can be isolated from each other, that is, the airflow in the first air duct 10a will not flow directly into the second air duct 10b. Obviously, in this operating state, the air conditioner 100 discharges air through the first air outlet 1b and the second air outlet 1c.

[0064] 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 the airflow after heat exchange is blown out through the first air outlet 1b to regulate the ambient temperature. The airflow in the second air duct 10b does not exchange heat with the heat exchange component 2, so the airflow blown out from the second air outlet 1c can be used for indoor air circulation to improve indoor air circulation.

[0065] 3. The air outlet switching component 5 switches the second air duct 10b to the outlet of the exhaust port 1d, and the second air outlet 1c does not produce air. Meanwhile, the air duct switching component 6 switches to the first switching state. At this time, the airflow at the air inlet 1a flows directly into the first air duct 10a and cannot flow directly into the second air duct 10b. A portion of the airflow in the first air duct 10a can be blown out through the first air outlet 1b, and another portion of the airflow in the first air duct 10a can flow into the second air duct 10b and be blown out through the exhaust port 1d. Obviously, in this operating state, the air conditioner 100 achieves air outlet through the first air outlet 1b and exhaust through the exhaust port 1d.

[0066] 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. A portion of the airflow after heat exchange is blown out through the first air outlet 1b to regulate the ambient temperature. Another portion of the airflow after heat exchange flows to the second air duct 10b and is blown out through the exhaust vent 1d to achieve ventilation.

[0067] 4. The air outlet switching component 5 switches the second air duct 10b to the outlet of the exhaust port 1d, and the second air outlet 1c does not produce air. The air duct switching component 6 switches to the second switching state. At this time, part of the airflow at the air inlet 1a flows directly to the first air duct 10a, and part of it flows directly into the second air duct 10b. The airflow in the first air duct 10a can be blown out through the first air outlet 1b, and the airflow in the second air duct 10b can be blown out through the exhaust port 1d. The first air duct 10a and the second air duct 10b can be isolated from each other, that is, the airflow in the first air duct 10a will not flow directly into the second air duct 10b. Obviously, in this operating state, the air conditioner 100 achieves air outlet through the first air outlet 1b and exhaust through the exhaust port 1d.

[0068] 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 the airflow after heat exchange is blown out through the first air outlet 1b to regulate the ambient temperature. The airflow in the second air duct 10b does not exchange heat with the heat exchange component 2, and the airflow blown out from the exhaust vent 1d is discharged to the outside to achieve ventilation.

[0069] 5. The air outlet switching component 5 switches the second air duct 10b to allow air to be discharged through both the second air outlet 1c and the exhaust outlet 1d. Meanwhile, the air duct switching component 6 switches to the first switching state. At this time, the airflow at the air inlet 1a flows directly into the first air duct 10a and cannot flow directly into the second air duct 10b. A portion of the airflow in the first air duct 10a can be blown out through the first air outlet 1b, and another portion of the airflow in the first air duct 10a can flow into the second air duct 10b and be blown out through the second air outlet 1c and the exhaust outlet 1d. Obviously, in this operating state, the air conditioner 100 discharges air through the first air outlet 1b and the second air outlet 1c and exhausts air through the exhaust outlet 1d.

[0070] 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. Then, part of the airflow after heat exchange is blown out through the first air outlet 1b, and part flows to the second air duct 10b and is blown out through the second air outlet 1c, so as to quickly adjust the ambient temperature. Another part of the airflow after heat exchange flows to the second air duct 10b and is blown out through the exhaust vent 1d to achieve ventilation.

[0071] 6. When the air outlet switching component 5 switches the second air duct 10b to allow air to be discharged through both the second air outlet 1c and the exhaust outlet 1d, the air duct switching component 6 switches to the second switching state. At this time, part of the airflow at the air inlet 1a flows directly to the first air duct 10a, and part of it flows directly into the second air duct 10b. The airflow in the first air duct 10a can be blown out through the first air outlet 1b, and the airflow in the second air duct 10b can be blown out through the second air outlet 1c and the exhaust outlet 1d. The first air duct 10a and the second air duct 10b can be isolated from each other, that is, the airflow in the first air duct 10a will not flow directly into the second air duct 10b. Obviously, in this operating state, the air conditioner 100 discharges air through the first air outlet 1b and the second air outlet 1c, and exhausts air through the exhaust outlet 1d.

[0072] 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 the airflow after heat exchange is blown out through the first air outlet 1b to regulate the ambient temperature. The airflow in the second air duct 10b does not exchange heat with the heat exchange component 2. The airflow blown out from the second air outlet 1c can participate in the indoor air circulation. The airflow blown out from the exhaust vent 1d is discharged to the outside to achieve ventilation.

[0073] It is understandable that when the air conditioner 100 discharges air through the first air outlet 1b and the second air outlet 1c, it helps to expand the air supply range of the air conditioner 100 and facilitates the use of other functions of the air conditioner 100 to improve its applicability.

[0074] According to an embodiment of the present invention, the air conditioner 100 has a housing 1 having a first air outlet 1b, a second air outlet 1c, and an exhaust outlet 1d, and an air outlet switching component 5 is provided to switch the second air duct 10b to outlet air through at least one of the second air outlet 1c and the exhaust outlet 1d. The air duct switching component 6 has a first switching state and a second switching state, which effectively enriches the operating modes of the air conditioner 100, thereby facilitating the enrichment of the functions of the air conditioner 100 and enabling the air conditioner 100 to better meet actual differentiated needs.

[0075] In addition, the second air duct 10b can serve multiple functions as an air conditioning air outlet duct and an air conditioning air exhaust duct, which facilitates "multi-purpose use of one item", helps to reduce the number of components in the air conditioner 100, simplifies the structure of the air conditioner 100, and reduces costs.

[0076] In some embodiments of the present invention, such as Figures 10-12 As shown, the air duct switching component 6 includes a moving member 61, which is movable relative to the housing 1. A third air duct 610 is defined within the moving member 61. An air duct inlet 61a and an air duct outlet 61b are formed on the moving member 61, which communicate with the third air duct 610. The air duct outlet 61b is always connected to the second air duct 10b, that is, no matter what position the moving member 61 moves to, the air duct outlet 61b remains connected to the second air duct 10b. The moving member 61 can reciprocate between a first position and a second position. In the first position, the air duct inlet 61a is connected to the first air duct 10a, and the air duct inlet 61a is blocked from the air inlet 1a. At this time, the second air duct 10b is connected to the first air duct 10a through the third air duct 610. In the second position, the air duct inlet 61a is connected to the air inlet 1a, and the air duct inlet 61a is blocked from the first air duct 10a. At this time, the second air duct 10b is connected to the air inlet 1a through the third air duct 610. Therefore, the movement of the moving part 61 facilitates the switching of the air duct switching component 6 between the first switching state and the second switching state.

[0077] like Figure 7 As shown, the air duct switching component 6 also includes a drive assembly 62, which drives the moving part 61 to reciprocate between the first position and the second position. This facilitates the switching of the moving part 61 by controlling the drive assembly 62, improving the convenience of switching the moving part 61 between the first and second positions. At the same time, compared with manually operating the moving part 61, the moving part 61 does not need to have a control part extending outside the housing 1, which helps to ensure the sealing of the second air duct 10b and prevent air leakage from the second air duct 10b.

[0078] In some embodiments of the present invention, such as Figure 1 , Figure 10 and Figure 11 As shown, the moving member 61 includes a cylindrical portion 611, the inner cavity of which defines a third air duct 610. An air duct inlet 61a is formed on the peripheral wall of the cylindrical portion 611. One axial end of the cylindrical portion 611 is a closed end F1, and the other axial end of the cylindrical portion 611 is an open end F2. The open end F2 is configured as an air duct outlet 61b. The drive assembly 62 drives the moving member 61 to reciprocate along the axial direction of the cylindrical portion 611.

[0079] It is understood that the moving part 61 can be located at the junction of the first air duct 10a and the second air duct 10b. In the first position, the air duct inlet 61a is completely located in the first air duct 10a, so that the airflow in the second air duct 10b can flow through the air duct inlet 61a to the third air duct 610, and then through the air duct outlet 61b back into the second air duct 10b, so that the air duct switching part 6 switches to the first switching state. In the second position, the air duct inlet 61a is completely located in the second air duct 10b. At this time, the air duct inlet 61a can form the "airflow inlet" of the second air duct 10b. The airflow at the air inlet 1a can flow through the air duct inlet 61a to the third air duct 610, and then through the air duct outlet 61b back into the second air duct 10b, so that the air duct switching part 6 switches to the second switching state.

[0080] It should be noted that in the description of this application, "cylindrical" should be interpreted in a broad sense, such as cylindrical, polygonal, etc.

[0081] Of course, the arrangement of the moving part 61 is not limited to this; for example, the moving part 61 defines a third air duct 610, and the top of the moving part 61 has a first vent and a second vent that are respectively connected to the third air duct 610. In a first position, the first vent is connected to the first air duct 10a and the second vent is blocked from the air inlet 1a. In a second position, the second vent is connected to the air inlet 1a and the first vent is blocked from the first air duct 10a.

[0082] In some embodiments of the present invention, such as Figures 10-12 As shown, the air duct switching component 6 also includes a fixing member 63, on which a through hole 63a is formed. A cylindrical portion 611 passes through the through hole 63a, and the axial length of the cylindrical portion 611 is greater than the axial length of the through hole 63a, so that during the movement of the cylindrical portion 611, a portion of the cylindrical portion 611 always protrudes from the through hole 63a. The closed end F1 is surrounded by a first sealing ring 613, which can be located on the outer periphery of the closed end F1 and extend radially outward along the cylindrical portion 611. The open end F2 is surrounded by a second sealing ring 614, which can be located on the outer periphery of the open end F2 and extend radially outward along the cylindrical portion 611. This ensures that during the entire movement of the moving component 61, the first sealing ring 613 and the second sealing ring 614 are always located outside the through hole 63a.

[0083] like Figure 10 and Figure 11As shown, the end of the through hole 63a near the first sealing ring 613 is the first end F3. In the first position, the first sealing ring 613 is spaced apart from the first end F3 to form a first connecting port 6a that communicates with the first air duct 10a, and a portion of the air duct inlet 61a is exposed in the first connecting port 6a to communicate with the first air duct 10a. That is, the cylindrical portion 611 with a portion of the air duct inlet 61a extends out of the through hole 63a toward the side where the first air duct 10a is located, so that the aforementioned portion of the air duct inlet 61a communicates with the first air duct 10a through the first connecting port 6a. In the second position, the first sealing ring 613 covers the first end F3 to close the first connecting port 6a. At this time, the cylindrical portion 611 with the aforementioned portion of the air duct inlet 61a retracts into the through hole 63a, and the first sealing ring 613 and the first end F3 cooperate to separate the air duct inlet 61a from the second air duct 10b.

[0084] The end of the through hole 63a near the second sealing ring 614 is the second end F4. In the second position, the second sealing ring 614 is spaced apart from the second end F4 to form a second connecting port 6b that communicates with the air inlet 1a. A portion of the air duct inlet 61a is exposed in the second connecting port 6b to communicate with the air inlet 1a. That is, the cylindrical portion 611, which forms a portion of the air duct inlet 61a, extends through the through hole 63a toward the side where the second air duct 10b is located, so that the aforementioned portion of the air duct inlet 61a communicates with the air inlet 1a through the second connecting port 6b. In the first position, the second sealing ring 614 covers the second end F4 to close the second connecting port 6b. At this time, the cylindrical portion 611, which forms a portion of the air duct inlet 61a, retracts into the through hole 63a. The second sealing ring 614 and the second end F4 cooperate to separate the air duct inlet 61a from the air inlet 1a.

[0085] Therefore, by setting the fixing part 63 and cooperating with the moving part 61, the effective switching of the air duct switching part 6 is ensured.

[0086] For example, in Figure 10 and Figure 11In the example, the cylindrical part 611 moves vertically, the first sealing ring 613 is located above the second sealing ring 614, and the cylindrical part 611 moves upward until the second sealing ring 614 and the second end F4 abut against each other to seal 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 extends out of the through hole 63a so that the upper part of the air duct inlet 61a communicates with the first air duct 10a through the first connecting port 6a between the first sealing ring 613 and the first end F3. The lower part of the air duct inlet 61a is located in the through hole 63a. Then the second sealing ring 614 and the second end F4... F4 cooperates to separate the entire air duct inlet 61a from the air inlet 1a; the cylindrical part 611 moves downward until the first sealing ring 613 and the first section stop abut to cover the first section. At this time, the moving part 61 is in the second position, the second sealing ring 614 is located below the second end F4, and the lower part of the air duct inlet 61a extends out of the through hole 63a so that the lower part of the air duct inlet 61a communicates with the air inlet 1a through the second connecting port 6b between the second sealing ring 614 and the second end F4. The upper part of the air duct inlet 61a is located in the through hole 63a. Then the first sealing ring 613 and the first end F3 cooperate to separate the entire air duct inlet 61a from the first air duct 10a.

[0087] Optionally, the entire peripheral wall of the cylindrical portion 611 has a grid structure, which defines the air outlet inlet 61a. Of course, multiple ventilation holes may also be formed on the peripheral wall of the cylindrical portion 611 to define the air outlet inlet 61a.

[0088] In some embodiments of the present invention, such as Figures 7-11 As shown, the second ventilation component 4 includes a fan housing 42, a second fan 41 disposed inside the fan housing 42, and an air inlet end 42a on the fan housing 42. A sleeve portion 612 is also provided on the side of the second sealing ring 614 away from the cylindrical portion 611. During the movement of the moving component 61, the sleeve portion 612 and the air inlet end 42a are always in inner and outer sleeve connection so that the air duct outlet 61b is always connected to the inner cavity of the fan housing 42. Thus, during the movement of the moving component 61, the sleeve portion 612 reciprocates relative to the air inlet end 42a, and the sleeve portion 612 and the air inlet end 42a are never separated. The air duct outlet 61b is always connected to the second air duct 10b, and the connection between the air duct outlet 61b and the second air duct 10b is simple and easy to implement. At the same time, the air inlet end 42a has a certain guiding effect on the movement of the sleeve portion 612.

[0089] For example, in Figure 7 , Figure 10 and Figure 11In the example, the air inlet 42a has a cylindrical structure and can be sleeved outside the sleeve portion 612. The drive assembly 62 includes a drive mechanism 621 and a drive motor 622. The drive mechanism 621 is connected to the second sealing ring 614 and is located outside the air inlet 42a. The drive mechanism 621 (e.g., the rack 6212 described later) and the sleeve portion 612 can jointly define a mating groove 612a. The air inlet 42a is inserted into the mating groove 612a, which helps to further enhance the guiding effect of the air inlet 42a on the movement of the moving part 61, ensuring smooth movement of the moving part 61. The drive motor 622 is mounted on the fan housing 42 to drive the sleeve portion 612 relative to the fan housing 42 through the drive mechanism 621. Of course, the air inlet 42a can also be located inside the sleeve portion 612.

[0090] Optionally, in Figure 11 In the example, when the moving part 61 is in the second position, the air inlet end 42a can abut against the wall of the mating groove 612a to restrict the moving part 61 from continuing to move. At this time, both the air inlet end 42a and the first end F3 apply a certain force to the moving part 61 to support the moving part 61, which is beneficial to improve the force on the drive component 62.

[0091] Optionally, in Figure 2 and Figure 5 In the example, the second ventilation component 4 further includes an air outlet frame 43, which is fixed to the air outlet end of the fan housing 42 to guide the airflow from the fan housing 42 to the second air outlet 1c and the exhaust port 1d; the air outlet frame 43 has ventilation openings corresponding to the second air outlet 1c and the exhaust port 1d, respectively. Of course, the air conditioner 100 of this application may also omit the air outlet frame 43 and define the airflow path between the fan housing 42 and the second air outlet 1c by the housing 1.

[0092] In some embodiments of the present invention, such as Figure 3 , Figure 7 and Figure 12 As shown, the heat exchange component 2 is located above the air duct switching component 6. The moving component 61 moves vertically up and down, and the fixing component 63 defines a water collection groove 63b surrounding the through hole 63a. The water collection groove 63b can be formed as an annular groove. The water collection groove 63b is arranged opposite to the heat exchange component 2. In the vertical direction, at least a portion of the orthographic projection of the heat exchange component 2 can be located within the orthographic projection range of the water collection groove 63b, so that the water collection groove 63b can be used to collect condensate on the heat exchange component 2, facilitating the collection and discharge of condensate. At the same time, since the through hole 63a has a certain axial length, the outer wall surface of the peripheral wall of the through hole 63a can participate in defining the water collection groove 63b, preventing water in the water collection groove 63b from flowing to other positions through the through hole 63a, thus ensuring the cleanliness of the air conditioner 100. The fixing component 63 can be directly or indirectly fixedly connected to the heat exchange component 2.

[0093] Furthermore, since the water receiving trough 63b is annular, it is convenient to make the water receiving trough 63b applicable to heat exchange components 2 with different structures, such as heat exchange components 2 being formed as cylindrical, or C-shaped, or including two sub-heat exchangers arranged side by side, etc., which is beneficial to improving the applicability of the fixing member 63.

[0094] In some alternative embodiments of the present invention, such as Figure 7 As shown, the drive assembly 62 includes a drive mechanism 621 and a drive motor 622. The drive motor 622 drives the moving part 61 to reciprocate along a straight line through the drive mechanism 621. The movement mode of the moving part 61 is simple, which makes it easier to simplify the structure of the drive mechanism 621, reduce costs, and at the same time, it helps to reduce the space occupied by the moving part 61 during the entire movement process, making it easier to free up more space for other components in the housing 1.

[0095] Optionally, such as Figure 7 As shown, the drive mechanism 621 includes a gear 6211 and a rack 6212. The drive motor 622 is connected to the gear 6211. The gear 6211 meshes with the rack 6212, so the gear 6211 rotates to drive the rack 6212 to reciprocate linearly, thereby realizing the movement of the moving part 61. The drive mechanism 621 has a simple structure and good drive load-bearing performance, which helps to ensure the smooth movement of the moving part 61. The rack 6212 is integrally formed with the moving part 61, which can save the assembly process of the rack 6212 and the moving part 61 and facilitate the processing of the rack 6212 and the moving part 61.

[0096] Of course, the rack 6212 can also be fixedly connected to the moving part 61 by assembly means. The structure of the drive mechanism 621 is not limited to this; for example, the drive mechanism 621 can also be constructed to include a lead screw and a nut, the lead screw is connected to the drive motor 622 so that it is driven to rotate by the drive motor 622, the lead screw and the nut are threadedly engaged, and the nut is fixed to the moving part 61, so that the nut drives the moving part 61 to reciprocate linear motion.

[0097] Optionally, in Figure 10 and Figure 11 In the example, the rack 6212 and the sleeve portion 612 can jointly define a mating groove 612a, and the air inlet end 42a is inserted into the mating groove 612a. The gear tooth structure of the rack 6212 is provided on the side of the rack 6212 away from the sleeve portion 612, and the gear 6211 is mated on 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.

[0098] Optionally, there can be multiple drive components 62, which can be spaced circumferentially along the third air duct 610 to ensure smooth movement of the moving part 61. Figure 7 and Figure 8 In the example, there are two drive components 62, which are arranged radially opposite each other along the third air duct 610; of course, there can be three or more drive components 62.

[0099] In some embodiments of the present invention, such as Figures 3-5 As shown, the first air duct 10a is located above the second air duct 10b, and the air duct switching component 6 is located between the first air duct 10a and the second air duct 10b, so that the air duct switching component 6 can connect or block the second air duct 10b and the first air duct 10a. 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 vertical direction. At the same time, when the air conditioner 100 is used for heating, the air outlet switching component 5 can be switched to allow the second air duct 10b to discharge air at least through the second air outlet 1c, and the air duct switching component 6 can be switched to the first switching state, so that both the first air outlet 1b and the second air outlet 1c blow out hot air. The second air outlet 1c is set at a lower position, which is convenient for the air conditioner 100 to achieve carpet-like air supply. Especially when the air conditioner 100 is a cabinet air conditioner, it effectively avoids large temperature differences between the upper and lower floors of the indoor space, and the lower floor temperature is lower, which may cause users to feel cold feet, thus improving the user's thermal comfort.

[0100] It should be noted that "the first air outlet 1b is higher than the second air outlet 1c" can mean that the first air outlet 1b is directly above or diagonally above the second air outlet 1c, or simply that the first air outlet 1b is higher than the second air outlet 1c in the vertical direction; for example, in Figure 1 In the example, both the first air outlet 1b and the second air outlet 1c are formed on the front side of the housing 1, and the first air outlet 1b is located directly above the second air outlet 1c.

[0101] Furthermore, in Figure 3 and Figure 4 In the example, the first air outlet 1b is located near the top of the housing 1, and the second air outlet 1c is located near the bottom of the housing 1. This makes the distance between the first air outlet 1b and the second air outlet 1c relatively large in the vertical direction. This helps to reduce the overlap between the air outlet areas corresponding to the first air outlet 1b and the second air outlet 1c when both outlets are discharging air. This facilitates further expansion of the air supply range of the air conditioner 100 and also helps to further avoid lower temperatures in the lower part of the indoor space, thus improving the uniformity of indoor ambient temperature.

[0102] Optionally, the opening area of ​​the first air outlet 1b is larger than the opening area of ​​the second air outlet 1c.

[0103] In some embodiments of the present invention, such as Figures 3-5As shown, the first fan 31 is positioned above the heat exchange component 2, which helps reduce the horizontal space occupied by the air conditioner 100. The first air outlet 1b is higher than the first fan 31. Therefore, in the airflow direction within the first air duct 10a, the first fan 31 is located downstream of the heat exchange component 2. The airflow from the air inlet 1a into the first air duct 10a first flows through the heat exchange component 2, then through the first fan 31, and finally exits through the first air outlet 1b. At least a portion of the air inlet 1a is opposite to the heat exchange component 2; either the entire air inlet 1a is opposite to the heat exchange component 2, or a portion of the air inlet 1a is opposite to the heat exchange component 2. This ensures the connection between the air inlet 1a and the first air duct 10a, guarantees the heat exchange area of ​​the airflow into the first air duct 10a, and facilitates the switching connection between the air inlet 1a and the second air duct 10b.

[0104] For example, in Figure 3 and Figure 4 In the example, the air duct switching component 6 can be connected to the lower end of the heat exchange component 2 to participate in dividing the internal space of the housing 1 into a first air duct 10a and a second air duct 10b. The air duct switching component 6 defines a third air duct 610. In the first switching state, the third air duct 610 connects the first air duct 10a and the second air duct 10b. In the second switching state, the third air duct 610 connects the air inlet 1a and the second air duct 10b.

[0105] Optionally, the first fan 31 is an axial flow fan, which helps to simplify 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 counter-rotating fan, etc.

[0106] In some embodiments of the present invention, such as Figures 3-5 As shown, the second fan 41 is located below the heat exchange component 2, which helps to reduce the space occupied by the air conditioner 100 in the horizontal direction. Since the second air outlet 1c and the exhaust outlet 1d are both lower than the second fan 41, the airflow flowing into the second air duct 10b flows downward toward at least one of the second air outlet 1c and the exhaust outlet 1d.

[0107] Optionally, the second fan 41 is an axial flow fan, which helps to simplify 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 counter-rotating fan, etc.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the air outlet switching component 5 includes a first switching valve 51 and a second switching valve 52. The first switching valve 51 is located at the second air outlet 1c and is used to open or close the second air outlet 1c. The second switching valve 52 is located at the exhaust outlet 1d and is used to open or close the exhaust outlet 1d.

[0112] As can be seen, when the first switch valve 51 opens the second air outlet 1c and the second switch valve 52 closes the exhaust outlet 1d, the air outlet switching component 5 switches the second air duct 10b to discharge air through the second air outlet 1c. When the first switch valve 51 closes the second air outlet 1c and the second switch valve 52 opens the exhaust outlet 1d, the air outlet switching component 5 switches the second air duct 10b to discharge air through the exhaust outlet 1d. When the first switch valve 51 opens the second air outlet 1c and the second switch valve 52 opens the exhaust outlet 1d, the air outlet switching component 5 switches the second air duct 10b to discharge air through both the second air outlet 1c and the exhaust outlet 1d. Of course, when the air conditioner 100 is turned off, the first switch valve 51 can close the second air outlet 1c and the second switch valve 52 can close the exhaust outlet 1d, which helps to prevent external dust and other contaminants from entering the second air duct 10b through the second air outlet 1c and the exhaust outlet 1d, thus ensuring the cleanliness of the air conditioner 100.

[0113] Therefore, by controlling the first switching valve 51 and the second switching valve 52, the switching control of the air outlet switching component 5 can be easily realized. The logic is simple and easy to implement.

[0114] Optionally, the first switching valve 51 is also used to adjust the air outlet direction of the second air outlet 1c. For example, the first switching valve 51 is formed as an air guide plate or a door. By changing the air outlet direction of the second air outlet 1c through the movement of the first switching valve 51, it is beneficial to further expand the air supply range of the air conditioner 100, so that the indoor air can form a larger circulation range and improve the circulation of indoor air.

[0115] Of course, the structure of the air outlet switching component 5 is not limited to this; for example, the air outlet switching component 5 can also be configured to include a switching valve, which is movable relative to the housing 1, and the switching valve is used to switch the opening of at least one of the second air outlet 1c and the exhaust outlet 1d. 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 outlet 1d. In the second switching position, the switching valve opens the exhaust outlet 1d and closes the second air outlet 1c. In the third switching position, the switching valve opens the second air outlet 1c and the exhaust outlet 1d.

[0116] 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, the air inlet 1a and the air outlet 1d are both formed on the outer casing 12, and the air outlet 1d is formed on the rear side of the housing 1.

[0117] Optionally, in Figure 1 and Figure 3 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.

[0118] In some embodiments of the present invention, the air conditioner 100 further includes a humidifying component disposed within the housing 1. The humidifying component is used to humidify the airflow passing through the second air duct 10b. When the air duct switching component 6 defines a third air duct 610, the humidifying component can also be configured to humidify the airflow passing through the third air duct 610, thereby regulating air humidity and reducing particulate matter and germs in the air to a certain extent, thus purifying the air and further enriching the functions of the air conditioner 100. The humidifying component can be understood as a component that increases air humidity.

[0119] It is understandable that when the humidifying component is used to humidify the airflow passing through the third air duct 610, the humidifying component does not need to be installed in the second air duct 10b, so as to free up more space for other components in the second air duct 10b.

[0120] In some embodiments of the present invention, the housing 1 has a pull-out opening opposite to the second air duct 10b, and the pull-out opening is located upstream of the second air outlet 1c in the airflow path of the second air duct 10b. The air conditioner 100 also includes a shelf that is pull-outably disposed at the pull-out opening, on which items to be dried, such as clothes, can be placed, so that the air conditioner 100 has a drying function. For example, when drying is required, if the air conditioner 100 is used for heating, the air duct switching component 6 can switch to the first switching state, so that part of the heat-exchanged airflow flows into the second air duct 10b and dries the items to be dried on the shelf to remove moisture, and finally flows out through at least one of the second air outlet 1c and the exhaust vent 1d. If the air conditioner 100 is in a cooling state, the air duct switching component 6 can switch to the second switching state, at which time a heating device, such as an electric auxiliary heater, can be used to heat the airflow to achieve drying.

[0121] Optionally, the second ventilation component 4 includes a fan housing 42, and a shelf is adapted to extend into the fan housing 42 so as to ensure that the airflow in the second air duct 10b blows onto the items to be dried on the shelf.

[0122] Other configurations and operations of the air conditioner 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0123] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
