Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to a vertical air conditioner. Background Technology

[0002] With the improvement of living standards, floor-standing air conditioners have become an indispensable household appliance. Floor-standing air conditioners are usually installed in living rooms, offices and other places because they can meet the heating and cooling needs of large areas.

[0003] In related technologies, floor-standing air conditioners typically have air outlets on the front of the casing, meaning the air conditioner can only blow air from the front. Since the air blown out by the air conditioner is at a low temperature, this air outlet method blows the air directly at people, reducing the comfort of the air conditioner for users. Summary of the Invention

[0004] This application discloses a vertical air conditioner that avoids the problem of direct airflow from the air conditioner, thereby improving the comfort of human users.

[0005] To achieve the above objectives, in a first aspect, embodiments of this application disclose a vertical air conditioner, comprising:

[0006] Indoor unit, the indoor unit includes:

[0007] The housing has an air outlet.

[0008] The air outlet includes:

[0009] The first air outlet is located on one side of the housing along its width.

[0010] The second air outlet is located on the other side of the housing along its width direction;

[0011] The third air outlet is located on the front side of the housing;

[0012] A duct structure is provided inside the housing and connected to the housing, and the duct structure defines a duct cavity that communicates with the air outlet;

[0013] The air duct cavity includes:

[0014] The first air duct connects the first air outlet and the second air outlet;

[0015] The second air duct is located above the first air duct along the height direction of the housing, and the second air duct is connected to the third air outlet;

[0016] A fan is disposed in the air duct cavity, the fan extends along the height direction of the housing and extends from the first air duct to the second air duct, and the fan is configured to introduce indoor air and blow it out from the air outlet;

[0017] A heat exchanger configured to exchange heat with indoor air entering the housing;

[0018] A drive motor, connected to the fan, is used to drive the fan to rotate;

[0019] The fan is configured to blow indoor air that has been heated by the heat exchanger out through the first air duct from the first air outlet and the second air outlet, and to blow indoor air that has not been heated by the heat exchanger out through the second air duct from the third air outlet.

[0020] The vertical air conditioner provided in this application has a first air outlet and a second air outlet on both sides of the casing, and a third air outlet on the front side of the casing. A first air duct connects the first air outlet and the second air outlet, and a second air duct connects the third air outlet. A fan extends from the first air duct to the second air duct. Because the fan can blow indoor air, after heat exchange by the heat exchanger, through the first air duct and out through the first air outlet and the second air outlet, the air conditioning air blown out from the air outlets on both sides of the indoor unit can lower the indoor temperature and avoid the problem of air conditioning air blowing directly on the user.

[0021] Building upon this, the fan can also blow unheated indoor air through the second duct and out through the third air outlet. That is, the air blown out through the third air outlet on the front side does not pass through a heat exchanger, so the air is not cold. Since the air blown out through the first and second air outlets on both sides passes through the heat exchanger, lowering the indoor temperature, the air blown out through the third air outlet, even without heat exchange, still feels cool compared to not having the air conditioning on. Furthermore, the air blown out through the third air outlet can promote indoor air circulation, quickly dispersing the air conditioning air throughout the room. Because of the increased airflow, the perceived temperature is lower than that of air conditioning air alone, achieving a "cool but not cold" effect, thus improving user comfort.

[0022] Meanwhile, since the fan used to blow out ambient air and the fan used to blow out air conditioning air are the same fan, the original structure of the air conditioner can be fully utilized. The fan can be extended from the first air duct to the second air duct along the height of the casing. Without significantly altering the internal structural design of the casing, the structure can be kept simple while taking into account the characteristics of being able to blow out ambient air that has not been heated and air conditioning air that has been heated. This achieves the effect of "cool but not cold" by not blowing air conditioning air directly, thereby improving the comfort of human users.

[0023] As an optional implementation, in an embodiment of the first aspect of this application, the heat exchanger is arranged in relation to the fan located in the first air duct along the front-rear direction of the housing, so that the indoor air flowing through the first air duct exchanges heat with the heat exchanger and is blown out from the first air outlet and the second air outlet.

[0024] Furthermore, along the front-rear direction of the casing, the heat exchanger is not positioned corresponding to the fan located in the second air duct, so that the air flowing through the second air duct and blown out from the third air outlet does not exchange heat with the heat exchanger.

[0025] Along the front-to-back direction of the casing, the heat exchanger is positioned to correspond to the fan in the first air duct, but not to the fan in the second air duct. That is, no heat exchanger is installed in the second air duct. This ensures that the air blown out from the first and second air outlets through the first air duct is air conditioning air that has undergone superheat exchange with the heat exchanger, while the air blown out from the third air outlet through the second air duct is ambient air that has not undergone superheat exchange with the heat exchanger. With this configuration, the effect of "cool but not cold" can be achieved without significantly changing the structural design of the heat exchanger, and the piping design of the heat exchanger is also simpler.

[0026] As an optional implementation, in an embodiment of the first aspect of this application, the heat exchanger includes:

[0027] The first heat exchange section is arranged along the front and rear direction of the casing, corresponding to the fan located in the first air duct. The first heat exchange section is configured to exchange heat with the indoor air flowing through the first air duct, so that the indoor air after heat exchange through the first heat exchange section is blown out from the first air outlet and the second air outlet.

[0028] The second heat exchange section is located above the fan in the second air duct along the height direction of the casing.

[0029] The second heat exchange section is configured to perform heat exchange on the indoor air flowing through the second air duct, so that the indoor air after heat exchange in the second heat exchange section is blown out from the third air outlet; or, it may not perform heat exchange on the indoor air flowing through the second air duct, so that the indoor air that has not undergone heat exchange is blown out from the third air outlet.

[0030] By setting the first heat exchange section to correspond to the fan located in the first air duct and setting the second heat exchange section to correspond to the fan located in the second air duct, that is, the two heat exchange sections of the heat exchanger correspond to the two air ducts respectively, it is possible to control whether the air entering the two air ducts undergoes heat exchange or not, thereby realizing different air outlet modes of the two air ducts.

[0031] When it is necessary to blow out "cool but not cold" air, the operation of the first heat exchange unit can be controlled so that the air conditioner air after heat exchange in the first heat exchange unit passes through the first air duct and is blown out from the first air outlet and the second air outlet. Meanwhile, the operation of the second heat exchange unit is controlled so that the air passing through the second air duct is unheated air and is blown out from the third air outlet. The combined effect of these two functions achieves the effect of the air conditioner blowing out "cool but not cold" air.

[0032] When a user needs the first, second, and third air outlets to all blow out air that has been heated by the heat exchanger, the first and second heat exchange sections can be controlled to operate separately. This allows the air blown out of the first and second air ducts to undergo heat exchange, and then the air is blown out from the first, second, and third air outlets together, achieving a large air volume and a cooling effect from the air conditioner.

[0033] This allows for more diverse air conditioning modes, enabling users to choose the appropriate blowing mode based on their different needs and improving the user experience.

[0034] As an optional implementation, in the embodiment of the first aspect of this application, at least one first diverter is provided on the inlet pipe of the first heat exchange section and the inlet pipe of the second heat exchange section; or,

[0035] The outlet pipes of the first heat exchange section and the outlet pipes of the second heat exchange section are provided with at least one second diverter.

[0036] By installing at least one first diverter on the inlet pipe of the first heat exchange section and the inlet pipe of the second heat exchange section, or by installing at least one second diverter on the outlet pipe of the first heat exchange section and the outlet pipe of the second heat exchange section, the heat exchanger can be divided into two heat exchange systems through process design, so that the first heat exchange section and the second heat exchange section can be controlled separately to achieve different air outlet modes of the first air duct and the second air duct.

[0037] As an optional implementation, in an embodiment of the first aspect of this application, the fan is provided with a first partition, which is configured to divide the fan into a first fan section and a second fan section, the first fan section being located in the first air duct and the second fan section being located in the second air duct.

[0038] If the fans located in two air ducts are connected internally, it will cause cross-flow of air between the two ducts. This will not only reduce the cooling and heating efficiency, but may also cause internal airflow turbulence and noise. Therefore, by installing a first baffle inside the fan, the internal structure of the fan is separated, preventing cross-flow of air between the upper and lower air ducts and improving the cooling or heating efficiency of the air conditioner.

[0039] As an optional implementation, in an embodiment of the first aspect of this application, the air duct structure includes:

[0040] The air duct body is connected to the housing and defines the air duct cavity;

[0041] A duct separator is disposed in the duct cavity and connected between the duct body and the heat exchanger to separate the duct cavity into a first duct and a second duct. The duct separator has a through hole through which the fan passes, so that the first fan section is located in the first duct and the second fan section is located in the second duct.

[0042] The design of the air duct structure includes an air duct body and an air duct separator. The air duct separator is set in the air duct cavity formed by the air duct body to divide the air duct cavity into upper and lower parts to form the first air duct and the second air duct. While realizing the separation of the air duct to avoid mutual interference between the air supply of the two air ducts, it can make the air duct structure simpler, make full use of the original air conditioner structure, and not significantly modify the structure of the air conditioner. It also helps to simplify the assembly process and improve assembly efficiency.

[0043] As an optional implementation, in an embodiment of the first aspect of this application, the outer peripheral surface of the first partition is provided with an annular groove, and at least a portion of the duct separator extends into the annular groove along the radial direction of the fan.

[0044] The fan is divided by a first partition between the first and second fan sections, making full use of the original structure of the fan and resulting in a more rational structural design. Furthermore, the first partition is equipped with an annular groove, into which at least a portion of the duct separator extends, increasing the airflow path and preventing cross-flow between the first and second ducts, thereby reducing the mutual interference between the two ducts.

[0045] As an optional implementation, in an embodiment of the first aspect of this application, the diameter of the first fan section and / or the second fan section is D1, and the diameter of the first baffle at the annular groove is d1, wherein D1 and d1 satisfy: D1≥d1+10.

[0046] If D1 is less than d1+10, the depth of the annular groove is too small, and the portion of the duct separator that can penetrate into the annular groove is too small, resulting in poor airflow obstruction and severe cross-flow between the upper and lower ducts. By setting D1 to be greater than d1+10, that is, the depth of the annular groove is at least 5cm, the duct separator can extend sufficiently into the annular groove, effectively preventing airflow interference between the upper and lower ducts.

[0047] As an optional implementation, in an embodiment of the first aspect of this application, the duct separator has an upper surface and a lower surface disposed opposite to each other along the height direction of the housing, the upper surface and / or the lower surface being provided with a protruding ring portion, the protruding ring portion extending along the height direction of the housing to the first fan section and / or the second fan section, and being disposed circumferentially around the first fan section and / or the second fan section.

[0048] By providing a raised ring on the upper and / or lower surface of the duct separator and surrounding the first and / or second fan sections, the path of gas flow along the radial direction of the fan can be blocked, effectively blocking the flow of air and making it more effective to prevent cross-flow between the first and second ducts.

[0049] As an optional implementation, in an embodiment of the first aspect of this application, the height of the first fan section in the height direction of the casing is H, and the height of the second fan section in the height direction of the casing is h, where h:H≥1:5, and / or h:H≤1:2.

[0050] The height ratio of the second fan section to the first fan section should be no less than 1:5, meaning the height of the second fan section cannot be less than one-fifth of the height of the first fan section. If the height ratio is less than 1:5, the second fan section will be too low, affecting the air volume and velocity within the second duct. This will prevent the airflow from the third air outlet from effectively dispersing into the room, resulting in poor indoor air circulation and hindering the acceleration of airflow dispersion, thus affecting the cooling or heating performance of the air conditioner. Conversely, if the first fan section is too high, it will compress the space of the first duct, causing the third air outlet to be positioned closer to the top of the casing. This will limit the airflow range of the third air outlet and result in excessive air volume and velocity in the first fan section, potentially causing the air to blow directly onto the user and hindering the effectiveness of the second fan section. Therefore, satisfying this relationship ensures that the first fan section is not too high and the second fan section is not too low, thus ensuring that both the first and second fan sections have reasonable air volume. This guarantees the cooling effect of the air conditioning air blown out by the first fan section while also ensuring that the ambient air blown out by the second fan section increases the airflow efficiency of the room and improves the air circulation effect.

[0051] The height ratio of the second fan section to the first fan section should not exceed 1:2, meaning the height of the second fan section cannot exceed half the height of the first fan section. If the height ratio is greater than 1:2, the second fan section is too tall, excessively occupying the upper space of the air conditioner, resulting in an unreasonable positive electrode layout. Since the main function of an air conditioner is to blow out cooling or heating air, the airflow from the first fan section should be sufficiently large. If the height of the second fan section is greater than half that of the first fan section, when the unheated ambient air is blown out from the second duct, the excessive airflow will mix with the cooling air blown out from the first duct, reducing the cooling or heating effect, affecting the air conditioning performance, and increasing energy consumption. Meeting this relationship maintains a reasonable airflow ratio between the first and second fan sections and a rational spatial layout of the air conditioner, ensuring that the air conditioner's performance does not degrade.

[0052] The height ratio of the second fan section to the first fan section meets the requirement of 1:5≤h:H≤1:2, which can reasonably control the air volume of the first and second fan sections. While effectively ensuring the cooling effect of the first fan section, the air volume of the second fan section can drive the flow of indoor air and quickly disperse it, making the indoor temperature more comfortable for the human body.

[0053] As an optional implementation, in the embodiment of the first aspect of this application, the diameter of the first fan section is D, the diameter of the second fan section is d, d:D≥1:2, and / or d:D≤1:1.

[0054] The diameter ratio of the second fan section to the first fan section should be no less than 1:2, meaning the diameter of the second fan section cannot be less than half the diameter of the first fan section. If the diameter ratio is less than 1:2, the diameter of the second fan section will be too small, affecting the airflow of the second duct. Insufficient airflow will fail to meet the indoor airflow requirements, causing the air blown out of the first duct to not disperse quickly, resulting in a large indoor temperature gradient and affecting the user experience. Furthermore, small-diameter fans often need to operate at high speeds to compensate for insufficient airflow, generating higher operating noise and impacting the user experience. Therefore, by setting the diameter ratio of the second fan section to the first fan section to be greater than 1:2, the diameter of the second fan section is ensured to be adequate, guaranteeing sufficient airflow and delivery distance, thus ensuring effective indoor air circulation and providing users with a better perceived temperature.

[0055] The diameter ratio of the second fan section to the first fan section should not exceed 1:1, meaning the diameter of the second fan section cannot be larger than the diameter of the first fan section. If the diameter ratio of the second fan section to the first fan section is greater than 1:1, the diameter of the second fan section is too large, resulting in excessive wind speed and air volume, increasing the energy consumption of the air conditioner. Furthermore, it may cause the airflow from the second duct to be too concentrated in the upper area, affecting the uniformity and comfort of the overall indoor airflow.

[0056] The diameter ratio of the second fan section to the first fan section satisfies 1:2≤d:D≤1:2, which makes the air volume of the two fan sections more balanced. The air volume of the first fan section lowers the indoor temperature, while the air volume of the second fan section can achieve long-distance delivery and drive indoor air circulation. It also makes the airflow more stable, does not generate much noise, and reduces the energy consumption of the air conditioner.

[0057] As an optional implementation, the duct structure includes:

[0058] A first air duct component is connected to the housing and defines a first air duct.

[0059] A second air duct component is connected to the housing and is located above the first air duct component along the height direction of the housing, defining a second air duct.

[0060] By arranging the first and second air duct components along the height of the casing, respectively forming the first and second air ducts, and using two independent air duct components to form separate air ducts, the interior of the casing can be divided into two separate upper and lower sections to avoid airflow interference between the two air ducts. Furthermore, using two independent air duct components, each connected to the casing separately, is more beneficial to the structural strength of the air duct structure and the robustness of the connection, especially when the overall length of the indoor unit is relatively long.

[0061] Secondly, this application also discloses a vertical air conditioner, comprising:

[0062] Indoor unit, the indoor unit includes:

[0063] The housing has an air outlet.

[0064] A fan that extends along the height of the housing and is configured to draw in indoor air and blow it out from the air outlet;

[0065] A heat exchanger configured to exchange heat with indoor air entering the housing;

[0066] A drive motor, connected to the fan, is used to drive the fan to rotate;

[0067] The air outlet includes:

[0068] The first air outlet is located on one side of the housing along its width.

[0069] The second air outlet is located on the other side of the housing along its width direction;

[0070] The third air outlet is located on the front side of the housing;

[0071] A duct structure is provided inside the housing and connected to the housing, and the duct structure defines a duct cavity that communicates with the air outlet;

[0072] The air duct cavity includes:

[0073] The first air duct connects the first air outlet and the second air outlet;

[0074] The second air duct is located above the first air duct along the height direction of the housing, and the second air duct is connected to the third air outlet;

[0075] The fan includes:

[0076] The first cross-flow fan is disposed in the first air duct along the front-rear direction of the casing. The first cross-flow fan is disposed corresponding to the heat exchanger. The first cross-flow fan is configured to blow indoor air that has been heated by the heat exchanger out through the first air duct from the first air outlet and the second air outlet.

[0077] The second cross-flow fan is located above the first cross-flow fan along the height direction of the casing. The second cross-flow fan is disposed in the second air duct and is configured to blow indoor air that has not been heated by the heat exchanger out through the second air duct from the third air outlet.

[0078] As an optional implementation, in an embodiment of the second aspect of this application, the heat exchanger is arranged in relation to the first cross-flow fan along the front-rear direction of the housing, so that the indoor air flowing through the first air duct exchanges heat with the heat exchanger and is blown out from the first air outlet and the second air outlet;

[0079] Furthermore, along the front-rear direction of the casing, the heat exchanger is not located corresponding to the second cross-flow fan, so that the air flowing through the second air duct and blown out from the third air outlet does not exchange heat with the heat exchanger.

[0080] As an optional implementation, in an embodiment of the second aspect of this application, the heat exchanger includes:

[0081] The first heat exchange section is arranged along the front and rear direction of the casing, corresponding to the first cross-flow fan. The first heat exchange section is configured to exchange heat with the indoor air flowing through the first air duct, so that the indoor air after heat exchange in the first heat exchange section is blown out from the first air outlet and the second air outlet.

[0082] The second heat exchange section is located above the second heat exchange section along the height direction of the casing, and is arranged corresponding to the second cross-flow fan along the front-back direction of the casing.

[0083] The second heat exchange section is configured to perform heat exchange on the indoor air flowing through the second air duct, so that the indoor air after heat exchange in the second heat exchange section is blown out from the third air outlet; or, it may not perform heat exchange on the indoor air flowing through the second air duct, so that the indoor air that has not undergone heat exchange is blown out from the third air outlet.

[0084] As an optional implementation, in an embodiment of the second aspect of this application, the drive motor is disposed between the first cross-flow fan and the second cross-flow fan, and the drive motor includes:

[0085] A first drive shaft is connected to the first cross-flow fan and is used to drive the first cross-flow fan to rotate.

[0086] The second drive shaft is connected to the second cross-flow fan and is used to drive the second cross-flow fan to rotate.

[0087] By setting the drive motor as a dual-shaft motor, the first cross-flow fan and the second cross-flow fan can share a single drive motor. Under the action of a single drive motor, the first cross-flow fan and the second cross-flow fan can be driven to rotate simultaneously to achieve the purpose of air delivery, without excessively occupying the internal space of the casing, thus maximizing the utilization rate of the casing space.

[0088] As an alternative implementation, in an embodiment of the second aspect of this application, the drive motor is disposed above the second cross-flow fan.

[0089] By placing the drive motor above the second cross-flow fan, the space between the first and second cross-flow fans can be driven without occupying the space between them, thus avoiding excessive occupation of the duct cavity space and making the internal space layout of the indoor unit more reasonable.

[0090] As an optional implementation, in an embodiment of the second aspect of this application, the air duct structure includes:

[0091] A first air duct component is connected to the housing and defines a first air duct.

[0092] A second air duct component is connected to the housing and is located above the first air duct component along the height direction of the housing, defining a second air duct.

[0093] By arranging the first and second air duct components along the height of the unit casing, respectively forming the first and second air ducts, and using two independent air duct components to form separate air ducts, the interior of the unit casing can be divided into two separate upper and lower sections, used to house the first and second cross-flow fans respectively, thus avoiding mutual interference between the two cross-flow fans during air delivery. Furthermore, using two independent air duct components, each connected to the unit casing, is more beneficial to the structural strength of the air duct structure and the robustness of the connection, especially when the overall length of the indoor unit is relatively long.

[0094] As an optional implementation, in an embodiment of the second aspect of this application, the air duct structure includes:

[0095] The air duct body is connected to the housing and defines the air duct cavity;

[0096] A duct separator is disposed in the duct cavity and connected between the duct body and the heat exchanger to separate the duct cavity into a first duct and a second duct.

[0097] The design of the air duct structure includes the air duct body and the air duct partition. The air duct partition is set in the air duct cavity formed by the air duct body to divide the air duct cavity into upper and lower parts, which are used to accommodate the first cross-flow fan and the second cross-flow fan respectively. While realizing the separation of the air duct to avoid mutual interference between the air supply of the two cross-flow fans, it can also make the air duct structure simpler, simplify the assembly process, and help improve assembly efficiency.

[0098] Compared with the prior art, the beneficial effects of this application are:

[0099] The vertical air conditioner provided in this application has a first air outlet and a second air outlet on both sides of the casing, and a third air outlet on the front side of the casing. A first air duct connects the first air outlet and the second air outlet, and a second air duct connects the third air outlet. A fan extends from the first air duct to the second air duct. Since the fan can blow indoor air that has been heated by the heat exchanger through the first air duct from the first air outlet and the second air outlet, the air conditioning air blown out from the air outlets on both sides of the indoor unit can lower the indoor temperature and avoid the problem of air conditioning air blowing directly on the user.

[0100] Building upon this, the fan can also blow unheated indoor air through the second duct and out through the third air outlet. This means the air blown out through the third air outlet doesn't pass through a heat exchanger, so the air isn't cold. Since the air from the first and second air outlets on either side passes through the heat exchanger, lowering the indoor temperature, the air from the third air outlet, even without heat exchange, still feels cool compared to not having the air conditioning on. Furthermore, the air from the third air outlet promotes airflow, quickly dispersing the air conditioning air throughout the room. Because of this increased airflow, the perceived temperature is lower than that of air conditioning air alone, achieving a "cool but not cold" effect, thus improving user comfort.

[0101] Meanwhile, since the fan used to blow out ambient air and the fan used to blow out air conditioning air are the same fan, the original structure of the air conditioner can be fully utilized. The fan can be extended from the first air duct to the second air duct along the height of the casing. Without significantly altering the internal structural design of the casing, the structure can be kept simple while taking into account the characteristics of being able to blow out ambient air that has not been heated and air conditioning air that has been heated. This achieves the effect of "cool but not cold" by not blowing air conditioning air directly, thereby improving the comfort of human users. Attached Figure Description

[0132] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0133] In this application, the terms "upper," "left," "right," "front," "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0134] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0135] Furthermore, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0136] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0137] Air conditioners in related technologies typically have air outlets on the front of the casing. The air conditioning air is sent directly forward through the air outlets, which can cause the air conditioning air to blow directly onto the user, resulting in a poor user experience.

[0138] Based on this, the inventors set air outlets on both sides of the casing and set a first fan and heat exchanger for each air outlet, so that the air conditioning air blows to the side through the air outlet. This can reduce the indoor temperature and solve the problem of the air conditioning air blowing directly to the user. However, side blowing results in a limited air delivery range and a low air temperature, which leads to a poor sensory effect and low comfort.

[0139] Based on this, this application provides a first air outlet and a second air outlet on both sides of the casing, and a third air outlet on the front side of the casing. The first air duct is connected to the first air outlet and the second air outlet, and the third air outlet is connected to the third air outlet. The fan extends from the first air duct to the second air duct. Since the fan blows the indoor air, which has been heated by the heat exchanger, through the first air duct and out through the first air outlet and the second air outlet, the air conditioning air blown out from the air outlets on both sides of the indoor unit can lower the indoor temperature and avoid the problem of the air conditioning air blowing directly on the user.

[0140] Because the fan can also blow unheated indoor air through the second air duct and out through the third air outlet, meaning the air blown out through the third air outlet on the front side doesn't pass through the heat exchanger, the air isn't cold. Since the air blown out through the first and second air outlets on both sides passes through the heat exchanger, lowering the indoor temperature, the air blown out through the third air outlet, even without heat exchange, still feels cool compared to not having the air conditioning on. Furthermore, the air blown out through the third air outlet can promote indoor air circulation, quickly dispersing the air conditioning air throughout the room. Because the indoor air circulation is faster, the perceived temperature is lower than that of air conditioning air alone, achieving a "cool but not cold" effect, thus improving user comfort.

[0141] Meanwhile, since the fan used to blow out ambient air and the fan used to blow out air conditioning air are the same fan, the original structure of the air conditioner can be fully utilized. The fan can be extended from the first air duct to the second air duct along the height of the casing. Without significantly altering the internal structural design of the casing, the structure can be kept simple while taking into account the characteristics of being able to blow out ambient air that has not been heated and air conditioning air that has been heated. This achieves the effect of "cool but not cold" by not blowing air conditioning air directly, thereby improving the comfort of human users.

[0142] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0143] This application discloses a vertical air conditioner, which may include an indoor unit 100 and an outdoor unit 200. The indoor unit 100 is usually installed indoors, and the outdoor unit 200 is installed outdoors and connected to the indoor unit 100. The outdoor unit 200 mainly compresses and delivers refrigerant to the indoor unit 100 to achieve cooling or heating effects.

[0144] See Figure 1 In some embodiments, the indoor unit 100 includes a housing 10, which forms the overall appearance of the indoor unit 100. The housing 10 has a top and a bottom that are disposed opposite each other, and the direction from the top to the bottom of the housing 10 is the height direction of the housing 10.

[0145] Of course, in some embodiments, the housing 10 also has a left side and a right side that are arranged opposite to each other, as well as a front side and a rear side that are arranged opposite to each other. Taking the overall shape of the housing 10 as a square as an example, the direction from the left side of the housing 10 to the right side of the housing 10 is the width direction of the housing 10, and the direction from the front side of the housing 10 to the rear side of the housing 10 is the thickness direction of the housing 10.

[0146] It is understandable that in practical applications, the rear of the housing 10 is usually set towards the wall, and the front of the housing 10 is usually set towards the user.

[0147] In this embodiment, the height direction of the housing 10 is defined as Z, the width direction (left-right direction) of the housing 10 is defined as Y, and the thickness direction (front-back direction) of the housing 10 is defined as X, as an example for explanation.

[0148] Optionally, the housing 10 can be made of thermoplastic plastic, such as ABS (Acrylonitrile Butadiene Styrene) plastic, HIPS (High Impact Polystyrene) plastic, etc., which can make the molded housing 10 have heat resistance, impact resistance, and a smooth and easy-to-clean surface.

[0149] Combination Figure 2 and Figure 3 In some embodiments, the housing 10 is provided with an air inlet 101, through which indoor air can enter the interior of the housing 10.

[0150] In one example, the air inlet 101 can be located on the rear side of the housing 10 to ensure the aesthetics of the housing 10.

[0151] In another example, the air inlet 101 can also be located on the upper part of the casing 10, so that the air intake of the indoor unit 100 is not affected.

[0152] In another example, the air inlets 101 can also be located on the left and right sides of the casing 10 to increase the air intake of the indoor unit 100.

[0153] In some embodiments, the housing 10 is provided with an air outlet, through which air passing inside the housing 10 can be output to the room.

[0154] See Figure 3 In some embodiments, the indoor unit 100 includes an air duct structure 20, which is disposed inside the housing 10 and connected to the housing 10, and defines an air duct cavity 201 that communicates with the air outlet.

[0155] In some embodiments, the indoor unit 100 includes a fan 30 that extends along the height direction Z of the housing and is configured to draw in indoor air and blow it out from an air outlet.

[0156] It is understood that the fan 30 can be installed in the air duct cavity 201. The fan 30 is connected to the air duct structure 20. The fan 30 guides indoor air into the air duct cavity 201, and then blows the heat-exchanged air or the unheat-exchanged air into the room through the air outlet. In addition, the air duct structure 20 can fix the fan 30 and guide the air introduced by the fan 30, making the airflow more concentrated.

[0157] Driven by the fan 30, indoor air enters the air duct cavity 201 from the air inlet 101. When the heat exchanger 40 is set to correspond to the fan 30, the indoor air exchanges heat with the heat exchanger 40 to form air conditioning air, which is then blown out from the air outlet through the air duct cavity 201. When the fan 30 is not set to correspond to the heat exchanger 40, the indoor air that has not been heated passes through the air duct cavity 201 and is blown out from the air outlet.

[0158] In some embodiments, the indoor unit 100 includes a heat exchanger 40 configured to exchange heat with indoor air entering the housing 10 to absorb or release heat, thereby achieving a cooling or heating effect.

[0159] In some embodiments, the indoor unit 100 includes a drive motor 50, which is connected to the fan 30 and is used to drive the fan 30 to rotate.

[0160] For example, when the heat exchanger 40 is set to correspond to the fan 30, when the indoor unit 100 is running, the fan 30 can rotate under the drive of the drive motor 50, so that indoor air enters the interior of the casing 10 from the air inlet 101. The indoor air forms air conditioning air after exchanging heat with the heat exchanger 40. The air conditioning air is in the air duct cavity 201 and is blown into the room under the action of the fan 30 to achieve temperature regulation.

[0161] For example, when the fan 30 is not equipped with a heat exchanger 40, when the indoor unit 100 is running, the fan 30 can rotate under the drive of the drive motor 50, so that indoor air enters the interior of the casing 10 from the air inlet 101 and is blown into the room under the action of the fan 30. This part of the air can be ambient air.

[0162] It should be noted that air conditioning air refers to the airflow after heat exchange has occurred through the heat exchanger 40, and can be either cold or hot air. Ambient air refers to the airflow that enters the indoor unit 100 but has not undergone heat exchange.

[0163] In related technologies, indoor units 100 typically only vent air from the front or side, causing the air conditioning air to blow directly at the user or having a limited air delivery range, thus affecting the user experience.

[0164] Based on this, see Figures 1 to 3 In some embodiments, the air outlet includes a first air outlet 102, which is disposed on one side of the housing 10 along its width direction Y. The first air outlet 102 is disposed on one side of the housing 10 to prevent direct airflow from the air conditioner.

[0165] In some embodiments, the air outlet includes a second air outlet 103, which is disposed on the other side of the housing 10 along its width direction Y. By providing a second air outlet 103 on the other side of the housing 10, direct airflow from the air conditioner can be avoided, while also increasing the air volume.

[0166] In some embodiments, the air outlet includes a third air outlet 104, which is disposed on the front side of the housing 10, thereby further expanding the air supply range.

[0167] Optionally, the first air outlet 102 and the second air outlet 103 can be elongated, oval, or other shapes, and the third air outlet 104 can be circular, square, or other shapes.

[0168] Combination Figure 4 and Figure 5 The indoor unit 100 also includes an air guide assembly 60, which can be installed on the housing 10 and correspondingly installed at the air outlet to guide the airflow blown out from the air outlet, so that the air outlet has different air delivery angles to meet the user's needs.

[0169] In some embodiments, the air guiding assembly 60 may include a first air guiding plate 61, with a corresponding first air guiding plate 61 provided at both the first air outlet 102 and the second air outlet 103. The first air guiding plate 61 is movably connected to the housing 10 or fixedly connected to the housing 10. That is, the first air guiding plate 61 can be oscillating or fixedly installed at the air outlet in an inclined manner. The first air guiding plate 61 can guide the airflow of the first air outlet 102 and the second air outlet 103 to adjust the air outlet angle of the first air outlet 102 and the second air outlet 103 and expand the air delivery range.

[0170] In some embodiments, the air guiding assembly 60 may include a second air guiding plate 62. A second air guiding plate 62 is correspondingly provided at both the first air outlet 102 and the second air outlet 103, and the second air guiding plate 62 is located on the side of the first air guiding plate 61 near the first air duct 201a. The first air guiding plate 61 is movably connected to the housing 10. The second air guiding plate 62 can guide the airflow of the first air outlet 102 and the second air outlet 103, thereby allowing the airflow to have diverse air delivery angles within the air outlet areas of the first air outlet 102 and the second air outlet 103.

[0171] Optionally, there can be multiple first air guide plates 61 and second air guide plates 62, such as three, four or five. Multiple first air guide plates 61 can be spaced apart along the width direction of the first air outlet 102 or the second air outlet 103, and multiple second air guide plates 62 can be spaced apart along the height direction Z of the casing.

[0172] In some embodiments, the air guide assembly 60 may include a third air guide plate 63, which is disposed corresponding to the third air outlet 104, and the second air guide plate 62 is movably connected to the housing 10. The second air guide plate 62 can swing left and right to adjust the air outlet direction of the third air outlet 104 in the left and right directions, thereby expanding the air delivery range of the third air outlet 104.

[0173] In some embodiments, the air guiding assembly 60 may further include a fourth air guiding plate 64, which is disposed corresponding to the third air outlet 104 and located in the second air duct 201b, adjacent to the third air guiding plate 63. The fourth air guiding plate 64 is movably connected to the second air duct component 22. The fourth air guiding plate 64 can swing up and down to adjust the air outlet direction of the third air outlet 104 in the vertical direction, thereby enabling the airflow to have diversified air delivery angles within the air outlet area of ​​the third air outlet 104.

[0174] Optionally, the number of the third air guide plate 63 and the fourth air guide plate 64 can be multiple, such as three, four or five. The multiple third air guide plates 63 can be spaced apart along their width direction Y, and the multiple fourth air guide plates 64 can be spaced apart along the height direction Z of the casing.

[0175] Continue reading Figure 5 The air guiding assembly 60 may include an air guiding element 65, which may be disposed on the outside of the third air outlet, that is, on the outside of the fourth air guiding plate 64. The air guiding element 65 may further adjust the air outlet direction of the third air outlet 104.

[0176] Optionally, the air guide 65 may include a fixing part 651 and a plurality of air guide strips 652. The fixing part 651 is connected to the housing 10, that is, the air guide 65 is mounted on the housing 10 via the fixing part 651. The fixing part 651 has a through hole adapted to the third air outlet 104, and the plurality of air guide strips 652 are disposed in the through hole. The plurality of air guide strips 652 not only guide the airflow, but also provide protection to prevent them from accidentally extending into the third air outlet 104.

[0177] See Figures 5 to 7 In some embodiments, the air duct cavity 201 includes a first air duct 201a, which is connected to the first air outlet 102 and the second air outlet 103, so that a portion of the airflow entering the housing 10 passes through the first air duct 201a and is blown into the room from the first air outlet 102 and the second air outlet 103.

[0178] In some embodiments, combined with Figure 7 The air duct cavity 201 includes a second air duct 201b, which is located above the first air duct 201a along the height direction Z of the housing. The second air duct 201b is connected to the third air outlet 104, so that a portion of the airflow entering the housing 10 passes through the second air duct 201b and is blown into the room from the third air outlet 104.

[0179] Continue reading Figures 4 to 7 In some embodiments, the fan 30 includes a first cross-flow fan 31, which is disposed in the first air duct 201a. The heat exchanger 40 is disposed corresponding to the first cross-flow fan 31, so that the air blown out from the first air outlet and the second air outlet 103 is air-conditioned air after heat exchange.

[0180] A cross-flow fan 31 is installed in the first air duct 201a, and a heat exchanger 40 is installed corresponding to the first cross-flow fan 31, so that the air blown out from the first air outlet and the second air outlet 103 is air-conditioned air that has undergone heat exchange.

[0181] In some embodiments, the fan 30 includes a second cross-flow fan 32, which is located above the first cross-flow fan 31 along the height direction Z of the casing, and the second cross-flow fan 32 is disposed in the second air duct 201b.

[0182] In one example, the heat exchanger 40 may not correspond to the second cross-flow fan 32. Functionally, the second cross-flow fan 32 is equivalent to a fan, which can blow ambient air from the first air outlet 102. The outlet temperature of the ambient air is the indoor temperature, which is higher than the outlet temperature of the first air outlet 102 and the second air outlet 103, thus achieving direct blowing.

[0183] Furthermore, under the action of the second cross-flow fan 32, long-distance air delivery can be achieved, and the indoor air flow can be fully promoted. The air conditioning air blown from the first air outlet 102 and the second air outlet 103 will be quickly dispersed into the room. At the same time, due to the increased air flow speed, the temperature perceived by the user will be lower than the perceived temperature of the air conditioning air blown out alone. Thus, under the same indoor temperature setting, the temperature of the air outlet can be increased under cooling conditions, reducing the power consumption of the indoor unit 100 and saving electricity during long-term use.

[0184] In another example, heat exchanger 40 can also be configured to correspond to the second cross-flow fan 32. When ambient air needs to be blown out from the second air duct 201b, the heat exchange system of the portion of heat exchanger 40 corresponding to the second cross-flow fan 32 can be controlled to not operate, thus allowing indoor air to bypass heat exchanger 40. This configuration not only enables the second cross-flow fan 32 to blow out ambient air, but also allows the second cross-flow fan 32 to blow out air conditioning air through the operation of the portion of heat exchanger 40 corresponding to the second cross-flow fan 32. Combined with the action of the first cross-flow fan 31, this ensures a sufficiently large airflow of air conditioning air.

[0185] Optionally, the axes of the first cross-flow fan 31 and the second cross-flow fan 32 can be located on the same straight line. This allows the rotation of the two cross-flow fans to remain balanced under the drive of the drive motor 50, avoiding additional vibration and noise. Furthermore, the drive motor 50 can simultaneously control the rotation of the first cross-flow fan 31 and the second cross-flow fan 32. In this way, the indoor unit 100 will simultaneously blow out both air conditioning air and ambient air, lowering the indoor temperature without making it too low, thus creating a more comfortable indoor temperature. Of course, the drive motor 50 can also control the rotation of the first cross-flow fan 31 and the second cross-flow fan 32 separately. For example, when rapid cooling of the room is needed, the drive motor 50 can control only the first cross-flow fan 31 to blow out air conditioning air from the first air outlet 102 and the second air outlet 103, quickly lowering the indoor temperature. As another example, if the user needs to accelerate indoor airflow, the drive motor 50 can control only the second cross-flow fan 32 to blow out ambient air from the third air outlet 104, accelerating indoor airflow.

[0186] It should be noted that the first air duct 201a and the second air duct 201b are separated so that there are two airflows entering the casing 10 from the air inlet 101. One airflow, under the action of the first cross-flow fan 31, exchanges heat with the heat exchanger 40 and enters the first air duct 201a; the other airflow, under the action of the second cross-flow fan 32, enters the second air duct 201b directly without heat exchange.

[0187] In some embodiments, the first cross-flow fan 31 is configured to blow indoor air, after heat exchange with the heat exchanger 40, out from the first air outlet 102 and the second air outlet 103. That is, the first cross-flow fan 31 is correspondingly provided with the heat exchanger 40, and the first cross-flow fan 31 with the heat exchanger 40 can realize long-distance delivery of air conditioning air.

[0188] In some embodiments, the second cross-flow fan 32 is configured to blow unheated indoor air out of the third air outlet 104.

[0189] It is worth noting that the second cross-flow fan 32 is configured to blow unheated indoor air out of the third air outlet 104, and several examples are possible:

[0190] In some examples, the second cross-flow fan 32 is not equipped with a heat exchanger 40. That is, the heat exchanger 40 only extends from the bottom to the top of the first cross-flow fan 31. The outlet air temperature will be higher than the outlet air temperature of the first cross-flow fan 31 after passing through the heat exchanger 40, which can achieve direct airflow.

[0191] In other examples, the second cross-flow fan 32 is also equipped with a heat exchanger 40, but the internal piping of the heat exchanger 40 is divided into two heat exchange systems. When the second cross-flow fan 32 blows out unheated indoor air, the corresponding part of the heat exchanger 40 of the second cross-flow fan 32 does not operate. Therefore, even if the indoor air passes through this part of the heat exchanger 40, it does not participate in heat exchange and can still blow out ambient air.

[0192] The fan 30 in this embodiment can also be an integrally installed fan, which will be discussed below. Figures 8 to 13 This section will be introduced.

[0193] Combination Figure 8 In some embodiments, the fan 30 is disposed in the air duct cavity 201, the fan 30 extends along the height direction Z of the housing 10 and extends from the first air duct 201a to the second air duct 201b, and the fan 30 is configured to introduce indoor air and blow it out from the air outlet.

[0194] It is understood that the fan 30 can be integrated into one unit, that is, the fan 30 is a single fan that extends into the first air duct 201a and the second air duct 201b, so that both the first air duct 201a and the second air duct 201b contain a portion of the fan 30.

[0195] In some embodiments, the fan 30 is configured to blow indoor air, after being heated by the heat exchanger 40, through the first air duct 201a from the first air outlet 102 and the second air outlet 103. That is, the portion of the fan 30 located in the first air duct 201a is correspondingly provided with the heat exchanger 40, and the indoor air, after being heated by the heat exchanger 40, is blown out of the first air outlet 102 and the second air outlet 103 by the fan 30 in the first air duct 201a.

[0196] In some embodiments, the fan 30 is further configured to blow indoor air that has not been heated by the heat exchanger 40 through the second air duct 201b out of the third air outlet 104. That is, the air flowing through the second air duct 201b and blown out of the third air outlet 104 can be ambient air that has not been heated.

[0197] The vertical air conditioner provided in this application has a first air outlet 102 and a second air outlet 103 on both sides of the casing, and a third air outlet 104 on the front side of the casing. A first air duct 201a is connected to the first air outlet 102 and the second air outlet 103, and a second air duct 201b is connected to the third air outlet 104. A fan 30 extends from the first air duct 201a to the second air duct 201b. Since the fan 30 blows the indoor air, which has been heated by the heat exchanger 40, through the first air duct 201a from the first air outlet 102 and the second air outlet 103, the air conditioning air blown out from the air outlets on both sides of the indoor unit can lower the indoor temperature and avoid the problem of the air conditioning air blowing directly on the user.

[0198] Based on this, since the fan 30 can also blow unheated indoor air out through the second air duct 201b from the third air outlet 104, that is, the air blown out through the front third air outlet 104 does not pass through the heat exchanger 40 for heat exchange, so the blown air is not cold. While the air blown out through the first air outlet 102 and the second air outlet 103 on both sides passes through the heat exchanger 40, lowering the indoor temperature, the air blown out through the third air outlet 104, even without heat exchange, still feels cool compared to not having the air conditioning on. Furthermore, the air blown out through the third air outlet 104 can promote indoor air circulation, quickly dispersing the air conditioning air throughout the room. Because the indoor air circulation speed is increased, the perceived temperature is lower than that of air conditioning air alone, thus achieving a "cool but not cold" effect, which further improves user comfort.

[0199] Meanwhile, since the fan 30 used to blow out ambient air and the fan 30 used to blow out air conditioning air are the same fan 30, the original structure of the air conditioner can be fully utilized. The fan 30 can be extended from the first air duct 201a to the second air duct 201b along the height direction of the casing. Without significantly changing the internal structural design of the casing, the structure is kept simple while taking into account the characteristics of being able to blow out ambient air that has not been heated and air conditioning air that has been heated. This achieves the effect of "cool but not cold" by not blowing air conditioning air directly, thereby improving the comfort of human use.

[0200] It is worth noting that the fan 30 can blow indoor air that has been heated by the heat exchanger 40 out through the first air duct 201a from the first air outlet 102 and the second air outlet 103, and blow indoor air that has not been heated by the heat exchanger 40 out through the second air duct 201b from the third air outlet 104. There are several examples of this, and the following will take the fan 30 as the same fan as an example to introduce them in detail.

[0201] In some embodiments, combined with Figure 8 Along the front-rear direction X of the casing 10, the heat exchanger 40 is arranged corresponding to the fan 30 located in the first air duct 201a, so that the indoor air flowing through the first air duct 201a exchanges heat with the heat exchanger 40 and is blown out from the first air outlet 102 and the second air outlet 103.

[0202] In some embodiments, along the front-rear direction X of the housing 10, the heat exchanger 40 is not configured to correspond to the fan 30 located in the second air duct 201b, so that the air flowing through the second air duct 201b and blown out from the third air outlet 104 does not exchange heat with the heat exchanger 40.

[0203] In other words, in this embodiment, the heat exchanger 40 has a heat exchange system and is only installed in the front-rear direction X of the casing 10, corresponding to the fan 30 located in the first air duct 201a. In the height direction of the casing 10, the extension length of the heat exchanger 40 in the height direction Z of the casing is less than the extension length of the fan 30. Specifically, the extension length of the heat exchanger 40 is approximately the same as that of the first air duct 201a, and it is only installed in the first air duct 201a, corresponding to the fan 30 located in the first air duct 201a, and does not extend to the position corresponding to the second air duct 201b.

[0204] Along the front-rear direction X of the casing 10, the heat exchanger 40 is positioned corresponding to the fan 30 located in the first air duct 201a, but not corresponding to the fan 30 located in the second air duct 201b. That is, the heat exchanger 40 is not installed in the second air duct 201b. This ensures that the air blown out from the first air outlet 102 and the second air outlet 103 through the first air duct 201a is air conditioning air that has undergone superheat exchange with the heat exchanger 40, while the air blown out from the third air outlet 104 through the second air duct 201b is ambient air that has not undergone superheat exchange with the heat exchanger 40. With this configuration, the effect of "cool but not cold" can be achieved without significantly changing the structural design of the heat exchanger 40, and the piping design of the heat exchanger 40 is also simpler.

[0205] Combination Figure 9 In some embodiments, the heat exchanger 40 includes a first heat exchange section 41, which is arranged in the front-rear direction X of the housing 10, and the first heat exchange section 41 is provided corresponding to the fan 30 located in the first air duct 201a.

[0206] In some embodiments, the heat exchanger 40 includes a second heat exchange section 42, which is located above the housing 10 along the height direction Z and along the front-rear direction X of the housing 10. The second heat exchange section 42 is disposed corresponding to the fan 30 located in the second air duct 201b.

[0207] In some embodiments, the first heat exchange section 41 is configured to exchange heat with indoor air flowing through the first air duct 201a, so that the indoor air after heat exchange by the first heat exchange section 41 is blown out from the first air outlet 102 and the second air outlet 103.

[0208] In some embodiments, the second heat exchange section 42 is configured not to exchange heat with the indoor air flowing through the second air duct 201b, so that the unexchanged indoor air is blown out from the third air outlet 104.

[0209] In other words, the fan 30 located in the first air duct 201a is equipped with a heat exchanger 40, and the fan 30 located in the second air duct 201b is also equipped with a heat exchanger 40. Specifically, the heat exchanger 40 is divided into two heat exchange sections. When the fan 30 located in the second air duct 201b blows out unheated indoor air, the second heat exchange section 42 of the corresponding fan 30 can be turned off. So even if the indoor air passes through the second heat exchange section 42, it does not participate in heat exchange and can still blow out ambient air.

[0210] Of course, in some embodiments, the second heat exchange section 42 can also be configured to exchange heat with the indoor air flowing through the second air duct 201b, so that the indoor air after heat exchange in the second heat exchange section 42 is blown out from the third air outlet 104. That is, the second heat exchange section 42 can be controlled to operate or not operate as needed, so as to select whether the air blown out through the third air outlet 104 is air-conditioned air that has undergone heat exchange or ambient air that has not undergone heat exchange.

[0211] By setting the first heat exchange section 41 to correspond to the fan 30 located in the first air duct 201a and setting the second heat exchange section 42 to correspond to the fan 30 located in the second air duct 201b, the two heat exchange sections of the heat exchanger correspond to the two air ducts respectively. It is possible to control whether the air entering the two air ducts undergoes heat exchange or not, thereby realizing different air outlet modes of the two air ducts.

[0212] When it is necessary to blow out "cool but not cold" air, the operation of the first heat exchanger 41 can be controlled so that the air conditioner air after heat exchange in the first heat exchanger 41 passes through the first air duct 201a and is blown out from the first air outlet 102 and the second air outlet 103. Meanwhile, the operation of the second heat exchanger 42 is controlled so that the air passing through the second air duct 201b is unexchanged air and is blown out from the third air outlet 104. The combined effect of these two actions achieves the effect of "cool but not cold" air delivery from the air conditioner.

[0213] When a user needs the first air outlet 102, the second air outlet 103, and the third air outlet 104 to all blow out air that has been heated by the heat exchanger 40, the first heat exchanger 41 and the second heat exchanger 42 can be controlled to operate separately, so that the air blown out by the first air duct 201a and the second air duct 201b undergoes heat exchange, and then air conditioning air is blown out from the first air outlet 102, the second air outlet 103, and the third air outlet 104 together, achieving the effect of large air volume and cool air from the air conditioner.

[0214] This allows for more diverse air conditioning modes, enabling users to choose the appropriate blowing mode based on their different needs and improving the user experience.

[0215] It is understandable that the above design for the heat exchanger 40 also applies when the fan 30 includes a first cross-flow fan 31 and a second cross-flow fan 32. Specifically:

[0216] In some embodiments, along the front-rear direction X of the housing 10, the heat exchanger 40 is arranged corresponding to the first cross-flow fan 31 so that the indoor air flowing through the first air duct 201a exchanges heat with the heat exchanger 40 and is blown out from the first air outlet 102 and the second air outlet 103.

[0217] In some embodiments, the heat exchanger 40 is not configured to correspond to the second cross-flow fan 32 along the front-rear direction X of the housing 10, so that the air flowing through the second air duct 201b and blown out from the third air outlet 104 does not exchange heat with the heat exchanger 40.

[0218] In some embodiments, the heat exchanger 40 includes a first heat exchange section 41, which is disposed along the front-rear direction X of the housing 10 and corresponds to the first cross-flow fan 31.

[0219] In some embodiments, the heat exchanger 40 includes a second heat exchange section 42, which is located above the second heat exchange section 42 along the height direction Z of the housing 10 and along the front-rear direction X of the housing 10. The second heat exchange section 42 is provided corresponding to the second cross-flow fan 32.

[0220] The specific design of the heat exchanger 40 when the fan 30 includes the first cross-flow fan 31 and the second cross-flow fan 32 can be referred to the above introduction of the heat exchanger 40 when the fan 30 is an integrated fan, and will not be elaborated further here.

[0221] Combination Figure 9 In some embodiments, at least one first diverter 43 is provided on the inlet pipe of the first heat exchange section 41 and the inlet pipe of the second heat exchange section 42.

[0222] In some embodiments, the outlet pipe of the first heat exchange section 41 and the outlet pipe of the second heat exchange section 42 are provided with at least one second diverter 44.

[0223] By providing at least one first diverter 43 on the inlet pipe of the first heat exchange section 41 and the inlet pipe of the second heat exchange section 42, or by providing at least one second diverter 44 on the outlet pipe of the first heat exchange section 41 and the outlet pipe of the second heat exchange section 42, the heat exchanger can be divided into two heat exchange systems through process design, thereby enabling the first heat exchange section 41 and the second heat exchange section 42 to be controlled separately, so as to achieve different air outlet modes for the first air duct and the second air duct.

[0224] It is understood that the first heat exchange section 41 and the second heat exchange section 42 can be individually controlled by two solenoid valves 45. When both solenoid valves 45 are open, the first heat exchange section 41 and the second heat exchange section 42 are in working condition, and the indoor air passing through the first heat exchange section 41 and the second heat exchange section 42 undergoes heat exchange, without producing air conditioning air (hot or cold air); when the solenoid valve 45 of the first heat exchange section 41 is open and the solenoid valve 45 of the second heat exchange section 42 is closed, the first heat exchange section is in working condition and the second heat exchange section 42 is in non-working condition, the indoor air passing through the first heat exchange section 41 undergoes heat exchange and becomes air conditioning air, and the indoor air passing through the second heat exchange section 42 does not undergo heat exchange and becomes ambient air.

[0225] The two solenoid valves 45 can be opened and / or closed according to user needs, causing the first heat exchange section 41 and the second heat exchange section 42 to operate and / or not operate. For example, when the indoor temperature difference reaches a certain requirement, one of the heat exchange sections can be automatically shut down to reduce the power consumption of the air conditioner and save electricity; when one of the heat exchange sections is shut down, the outlet temperature of the corresponding air outlet of that heat exchange section is the indoor temperature, which can be blown directly to people, achieving "cool but not cold" air supply and improving human comfort.

[0226] The following will combine Figure 9 This section provides a brief introduction to the different air outlet modes of an air conditioner in cooling mode.

[0227] In some embodiments, the indoor unit 200 may include a compressor 200a, which is configured to compress a refrigerant such that a low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0228] In some embodiments, the outdoor unit 200 includes an outdoor heat exchanger 200b. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger 200b operates as a condenser, causing the refrigerant compressed by the compressor 200a to dissipate heat to the outdoor air through the outdoor heat exchanger 40 and condense. In the heating mode of the air conditioner, the outdoor heat exchanger 200b operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate through the outdoor heat exchanger 200b.

[0229] In some embodiments, the outdoor unit 200 includes a four-way valve 200c connected to the refrigerant circuit. The four-way valve 200c is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner performs a cooling mode or a heating mode.

[0230] When air conditioning air needs to be blown out from both the first and second air ducts, the refrigerant flowing out from the outdoor heat exchanger 200b is divided into two paths by the first diverter 43 and enters the first heat exchange section 41 and the second heat exchange section 42 respectively. At this time, both solenoid valves 45 are open. Under the action of the first diverter 43, the refrigerant in each heat exchange section can be divided into multiple paths to enter the interior. Under the action of the refrigerant, heat exchange occurs in the indoor space of the first heat exchange section 41 and the second heat exchange section 42. The multiple refrigerants in each heat exchange section are then combined into one path under the action of the second diverter 44 and flow to the outdoor unit 200.

[0231] When the first air duct 201a needs to blow out air conditioning air and the second air duct 201b needs to blow out ambient air, the solenoid valve 45 corresponding to the pipe installed in the first heat exchange section 41 opens and the solenoid valve 45 corresponding to the pipe installed in the second heat exchange section 42 closes. At this time, the refrigerant flowing out from the outdoor unit no longer flows to the second heat exchange section 42, but only flows in the heat exchange system of the first heat exchange section 41, so that the first heat exchange section 41 can operate.

[0232] If the fans 30 located in the two air ducts are connected internally, it will cause cross-flow of air between the two air ducts, which will not only reduce the cooling and heating effect, but may also cause internal airflow turbulence and generate noise.

[0233] Based on the above, in some embodiments, combined with Figure 10 The fan 30 is provided with a first partition 301, which is configured to divide the fan 30 into a first fan section 33 and a second fan section 34. The first fan section 33 is located in the first air duct 201a, and the second fan section 34 is located in the second air duct 201b.

[0234] By setting a first partition 301 inside the fan 30, the inside of the fan 30 is separated, preventing air from flowing between the upper and lower air ducts and improving the cooling or heating effect of the air conditioner.

[0235] See Figure 11 In some embodiments, the air duct structure 20 includes an air duct body 23 connected to the housing, and the air duct body 23 defines an air duct cavity.

[0236] In some embodiments, the air duct structure 20 includes an air duct separator 24, which is disposed in the air duct cavity and connected between the air duct body 23 and the heat exchanger to divide the air duct cavity into a first air duct 201a and a second air duct 201b.

[0237] In some embodiments, the air duct separator 24 is provided with a through hole 24a, and the fan 30 passes through the through hole 24a, so that the first fan section 33 is located in the first air duct 201a and the second fan section 34 is located in the second air duct 201b.

[0238] The design of the air duct structure 20 includes an air duct body 23 and an air duct separator 24. The air duct separator 24 is set in the air duct cavity formed by the air duct body 23 to divide the air duct cavity into upper and lower parts to form a first air duct 201a and a second air duct 201b. While achieving the separation of the air ducts to avoid mutual interference between the air supply of the two air ducts, it can make the structure of the air duct structure 20 simpler, make full use of the original structure of the air conditioner, and not significantly modify the structure of the air conditioner. It also helps to simplify the assembly process and improve assembly efficiency.

[0239] It is understandable that regardless of whether the fan 30 is integrated or separate, the first air duct 201a and the second air duct 201b can be formed by the air duct body 23 and the air duct separator 24. The main difference lies in the structure of the air duct separator 24.

[0240] Continue reading Figure 11The air duct partition 24 includes a second partition 241 and a third partition 242, both of which are connected between the air duct body 23 and the heat exchanger. The second partition 241 and the third partition 242 together form a through hole 24a and a convex ring portion 24b. The separate configuration of the air duct partition 24 facilitates assembly.

[0241] The structure of the air duct structure 20 will be introduced below, taking the fan 30 as an integrated unit as an example.

[0242] See Figure 10 In some embodiments, the outer peripheral surface of the first partition 301 is provided with an annular groove 30a, and at least a portion of the air duct separator 24 extends into the annular groove 30a along the radial direction of the fan 30.

[0243] The fan 30 is divided by a first partition 301 between the first fan section 33 and the second fan section 34, making full use of the original structure of the fan 30 and making its structural design more reasonable. Furthermore, the first partition 301 is equipped with an annular groove, and at least a portion of the duct separator 24 extends into the annular groove 30a, which increases the airflow path and prevents cross-flow between the first duct 201a and the second duct 201b, thereby reducing the mutual interference between the two ducts.

[0244] Optionally, the first partition 301 can be integrally formed and located between the first fan section 33 and the second fan section 34. In other embodiments, the first partition 301 may include an annular plate 301a and a mounting plate 302b. The annular plate 301a is connected along the height direction Z of the housing 10 between the first fan section 33 and the second fan section 34, and an annular groove 30a is located on the outer peripheral surface of the annular plate 301a. The mounting plate 302b is located inside the fan 30 and connected to the annular plate 301a to divide the interior of the fan 30 into two parts, thus preventing vertical airflow between the two ducts.

[0245] Optionally, combined Figure 12 and Figure 13 The formation of the first fan section 33 and the second fan section 34 utilizes the structure inherent in the fan 30 itself. Specifically, the fan 30 typically includes several blades 302, which are spaced apart along the height direction of the fan 30. Adjacent sets of blades 302 are connected by an annular plate 301a, which has through holes communicating with the interior of the fan 30. In this embodiment, the fan 30 is divided into the first fan section 33 and the second fan section 34 by using the annular plate 301a as a boundary, and an mounting plate 302b is provided on the annular plate 301a to separate the internal space of the fan 30, thereby preventing vertical airflow.

[0246] Thus, by using the annular plate 301a between the first fan section 33 and the second fan section 34, and setting the mounting plate 302b, the fan 30 is divided, making full use of the original structure of the fan 30 and making the structural design of the fan 30 more reasonable.

[0247] In some embodiments, combined with Figure 10 and Figure 13 The air duct separator 24 has an upper surface (not shown) and a lower surface (not shown) arranged opposite to each other along the height direction Z of the housing 10, and the upper surface and / or the lower surface is provided with a protruding ring portion 24b.

[0248] In some embodiments, the convex ring portion 24b extends along the height direction of the housing to the first fan section 33 and / or the second fan section 34, and is arranged circumferentially around the first fan section 33 and / or the second fan section 34. It can be understood that the convex ring portion 24b can block the annular groove 30a in the radial direction of the fan 30, thereby blocking the flow path of the airflow as much as possible without affecting the rotation of the fan 30.

[0249] By providing a raised ring 24b on the upper and / or lower surfaces of the air duct separator 24 and surrounding the first fan section 33 and / or the second fan section 34, the path of gas flow along the radial direction of the fan 30 can be blocked, effectively blocking the flow of airflow and making it more effective to prevent cross-flow between the first air duct 201a and the second air duct 201b.

[0250] It is understood that the upper surface of the air duct partition 24 is provided with a protruding ring portion 24b, or the lower surface of the air duct partition 24 is provided with a protruding ring portion 24b, or both the upper and lower surfaces of the air duct partition 24 are provided with protruding ring portions 24b.

[0251] Optionally, the aforementioned air duct partition 24 can be an integral piece. Of course, in some embodiments, the air duct partition 24 can also be a separate piece.

[0252] In some embodiments, combined with Figure 10 The diameter of the first fan section 33 and / or the second fan section 34 is D1, and the diameter of the first baffle 301 at the annular groove 30a is d1. D1 and d1 satisfy: D1 ≥ d1 + 10. Optionally, D1 and d1 satisfy: D1 ≥ d1 + 12, D1 ≥ d1 + 13, or D1 ≥ d1 + 15, etc. For example, D1 = d1 + 10, D1 = d1 + 12, or D1 = d1 + 15, etc.

[0253] If D1 is less than d1+10, the depth of the annular groove 30a is too small, and the portion of the duct separator 24 that can penetrate into the annular groove 30a is too small, resulting in poor airflow obstruction and severe cross-flow between the upper and lower ducts. By setting D1 to be greater than d1+10, that is, the depth of the annular groove 30a is at least 5cm, the duct separator 24 can penetrate sufficiently into the annular groove 30a, effectively preventing airflow interference between the upper and lower ducts.

[0254] See Figures 3 to 7 In some embodiments, the air duct structure 20 includes a first air duct component 21 connected to the housing 10, and the first air duct component 21 defines a first air duct 201a.

[0255] In some embodiments, the air duct structure 20 includes a second air duct component 22, which is connected to the housing 10. The second air duct component 22 is located above the first air duct component 21 along the height direction Z of the housing, and defines a second air duct 201b.

[0256] By setting the first air duct component 21 and the second air duct component 22 along the height direction Z of the housing 10, the first air duct 201a and the second air duct 201b are formed respectively. That is, by using two independent air duct components to form air ducts, the interior of the housing 10 can be divided into two separate upper and lower parts to avoid mutual interference of airflow in the two air ducts.

[0257] In addition, the use of two independent air duct components, which are connected to the housing 10 respectively, is more conducive to the structural strength of the air duct structure 20 and the firmness of the connection, given the relatively long overall length of the indoor unit 100.

[0258] It is understood that the method of forming the first air duct 201a and the second air duct 201b by the air duct structure 20, including the first air duct component 21 and the second air duct component 22 respectively, is applicable to both integrated and split-type fans. That is to say, when the fan 30 is an integrated fan, the air duct structure 20 can be an integrated air duct structure or a split-type air duct structure.

[0259] The following will briefly introduce the drive motor part, taking the fan 30, which includes the first cross-flow fan 31 and the second cross-flow fan 32, as an example.

[0260] In some embodiments, combined with Figure 3 and Figure 6 The drive motor is located between the first cross-flow fan 31 and the second cross-flow fan 32.

[0261] In some embodiments, the drive motor 50 includes a first drive shaft (not shown), which is connected to the first cross-flow fan 31 and is used to drive the first cross-flow fan 31 to rotate.

[0262] To make better use of the internal space of the housing 10, in some embodiments, the drive motor 50 includes a second drive shaft (not shown), which is connected to the second cross-flow fan 32 and is used to drive the second cross-flow fan 32 to rotate. That is, the drive motor 50 can be a dual-shaft drive motor 50, with the first cross-flow fan 31 and the second cross-flow fan 32 sharing one motor.

[0263] By setting the drive motor as a dual-shaft motor, the first cross-flow fan and the second cross-flow fan can share a single drive motor. Under the action of a single drive motor, the first cross-flow fan and the second cross-flow fan can be driven to rotate simultaneously to achieve the purpose of air delivery, without excessively occupying the internal space of the casing, thus maximizing the utilization rate of the casing space.

[0264] When the air duct structure includes the first air duct component 21 and the second air duct component 22, combined Figure 6 and Figure 7 In some embodiments, the first air duct component 21 and the second air duct component 22 are spaced apart along the height direction Z of the housing to form an installation space between them, and the drive motor 50 is disposed in the installation space. By using the space formed between the two air duct components to install the drive motor 50, it is possible to drive the first cross-flow fan 31 and / or the second cross-flow fan 32, while also providing certain support for the two cross-flow fans, making the cross-flow fans operate more smoothly.

[0265] By utilizing two duct components to form two ducts to accommodate two cross-flow fans, and by setting the first duct component 21 and the second duct component 22 at intervals to form an installation space 20a between them, and setting a dual-shaft drive motor 50 in the installation space, the first cross-flow fan 31 and the second cross-flow fan 32 can share a single drive motor 50. Under the action of a single drive motor 50, the first cross-flow fan 31 and the second cross-flow fan 32 can be driven to rotate simultaneously to achieve the purpose of air delivery. This approach avoids excessive occupation of the internal space of the housing 10 and makes full use of the structure of the two duct components, thereby maximizing the utilization rate of the space in the housing 10.

[0266] When the air duct structure includes an air duct body 23 and an air duct partition 24, in some embodiments, the drive motor 50 is disposed on the air duct partition 24. Based on dividing a complete air duct cavity 201 into upper and lower parts using the air duct partition 24, a dual-axis drive motor 50 can be used and disposed on the air duct partition 24. This reduces the number of drive motors 50, maximizing the use of internal space in the housing 10, while fully utilizing the air duct partition 24 to achieve structural reuse and a more rational structural layout within the housing 10.

[0267] In some embodiments, the drive motor 50 is positioned above the second cross-flow fan 32.

[0268] By placing the drive motor 50 above the second cross-flow fan 32, the space between the first cross-flow fan 31 and the second cross-flow fan 32 can be driven without occupying the space between them, thus avoiding excessive occupation of the space in the air duct cavity 201 and making the internal space layout of the indoor unit 100 more reasonable.

[0269] Of course, in another embodiment, there can be two drive motors 50, which drive the first cross-flow fan 31 and the second cross-flow fan 32 to rotate respectively. For example, one drive motor 50 is located at the bottom of the first cross-flow fan 31 to drive the first cross-flow fan 31, and the other drive motor 50 is located at the top of the second cross-flow fan 32 to drive the second cross-flow fan 32.

[0270] Combination Figure 3 and Figure 4 In some embodiments, the housing 10 includes a front housing 11 for forming the front exterior surface.

[0271] In some embodiments, the housing 10 further includes a rear housing 12, which can be connected to the front housing 11 to form the rear exterior surface. An air inlet 101 can be formed on the rear housing 12.

[0272] See Figures 14 to 17 In some embodiments, the housing 10 includes a panel 111, which is disposed opposite to the air duct structure 20, and a third air outlet 104 is provided on the panel 111. It can be understood that the panel 111 is disposed on the front side, facing the user. Since the second cross-flow fan 32 corresponding to the third air outlet 104 does not have a heat exchanger 40, the outlet air temperature is much higher than the outlet air temperature of the first cross-flow fan 31, which has a heat exchanger 40, and direct blowing can be achieved.

[0273] In some embodiments, the housing 10 includes a first side plate 112, which is connected to one side of the panel 111 along its width direction Y. The first side plate 112 is provided with a first air outlet 102 so that air conditioning air can be blown out from the side.

[0274] In some embodiments, the housing 10 includes a second side plate 113, which is connected to the other side of the panel 111 in the width direction Y. The second side plate 113 is provided with a second air outlet 103 so that the air conditioning air can be blown out from both sides of the housing 10.

[0275] Optionally, the first side plate 112 and the second side plate 113 can be arranged opposite each other along their own width direction Y, so that the first air outlet 102 and the second air outlet 103 are arranged opposite each other. This not only achieves a larger air volume, but also makes the air outlets on both sides of the casing 10 symmetrically arranged, which is more conducive to the aesthetics of the appearance.

[0276] By setting the first air outlet 102 and the second air outlet 103 on the first side panel 112 and the second side panel 113 respectively, and setting the third air outlet 104 on the panel 111, the three air outlets are located in different directions of the casing 10. At the same time, different air is blown out through the three air outlets, which expands the air supply range of the indoor unit 100 and effectively improves the user experience.

[0277] In some embodiments, the front housing 11 may include a panel 111, a first side panel 112, and a second side panel 113, with the two sides of the rear housing 12 respectively connected to the first side panel 112 and the second side panel. This arrangement ensures that the first air outlet 102 and the second air outlet 103 are formed on both sides of the front housing 11, with the second air outlet 103 formed on the front side of the front housing 11. This allows the air outlets to be as close to the user as possible, preventing obstruction that might occur if they were located on the rear housing 12, thus effectively guaranteeing the airflow and ensuring the performance of the indoor unit 100.

[0278] Of course, in other embodiments, the front shell 11 may include a panel 111, and the rear shell 12 may include a first side plate 112 and a second side plate 113. That is, the panel 111 constitutes at least a part of the front shell 11, and the first side plate 112 and the second side plate 113 constitute at least a part of the rear shell 12. In other words, the first air outlet 102 and the second air outlet 103 are formed on both sides of the rear shell 12, and the third air outlet 104 is formed on the front side of the front shell 11. By forming the air outlets on different components, the problem of affecting the structural strength by opening multiple air outlets on the same component is avoided.

[0279] Combination Figure 18 In some embodiments, the air duct structure 20 includes a volute tongue 211 that extends along the height direction Z of the housing. The volute tongue 211 has a first air outlet surface 211a so as to guide the airflow and change the airflow direction, which is more conducive to air outlet.

[0280] In some embodiments, the air duct structure 20 includes a volute 212 that extends along the height direction Z of the housing and together with the volute tongue 211 defines a first air duct 201a. The volute 212 has a second air outlet surface 212a to guide the airflow to the outlet of the volute 212 and to convert part of the dynamic pressure of the airflow into static pressure.

[0281] It should be noted that the shape and size of the volute tongue 211 and the volute shell 212 directly affect the airflow. When airflow passes through the volute tongue 211, the direction of airflow changes due to the presence of the volute tongue 211. To improve the airflow guiding effect of the first air duct component 21, the first air outlet surface 211a of the volute tongue 211 and the second air outlet surface 212a of the volute shell 212 are usually curved surfaces to better guide the airflow.

[0282] Specifically, since the first air outlet 102 and the second air outlet 103 are located on both sides of the housing 10, the panel 111 needs to be arranged opposite to the first air duct component 21 to guide the airflow to the side. Thus, the first air duct component 21 includes the aforementioned volute 212 and volute tongue 211.

[0283] In some embodiments, continue reading Figure 15 The panel 111 includes a first airflow guiding structure 11112a, which is configured to guide airflow to the first air outlet 102.

[0284] In some embodiments, one side of the first air guiding structure 11112a is connected to the first side plate 112, and the first air guiding structure 11112a is opposite to and spaced apart from the first air outlet surface 211a to form a first air outlet channel 202 connecting the first air duct 201a and the first air outlet 102.

[0285] By setting the first airflow guiding structure 11112a to be opposite to the first air outlet surface 211a of the volute tongue 211, a first air outlet channel 202 is formed, so that the first air duct 201a and the first air outlet 102 can be connected, and a part of the air from the first air duct 201a is guided to be output to the first air outlet 102.

[0286] In some embodiments, panel 111 includes a second airflow guiding structure 11112b, and a first airflow guiding structure 11112a is configured to guide airflow to the second air outlet 103.

[0287] In some embodiments, one side of the second flow guiding structure 11112b is connected to the first flow guiding structure 11112a at an angle along its width direction Y, and the other side of the second flow guiding structure 11112b is connected to the second side plate 113. The second flow guiding structure 11112b and the second air outlet surface 212a are opposite to each other and spaced apart, so as to form a second air outlet channel 203 between the two, which connects the first air duct 201a and the second air outlet 103.

[0288] By setting the second airflow guiding structure 11112b to be opposite to the second air outlet surface 212a of the volute 212, a second air outlet channel 203 is formed, so that the second air duct 201b and the second air outlet 103 can be connected, and another part of the air from the first air duct 201a is guided to be output to the second air outlet 103.

[0289] Under the action of the first guide structure 11112a and the second guide structure 11112b, the air conditioning air blown out by the first cross-flow fan 31 can be divided into two paths and blown out from the air outlets on both sides of the casing 10 respectively. The two paths of air can be guided to prevent the air conditioning air from circulating after being blown out from the first air duct 201a.

[0290] In some embodiments, the first guide structure 11112a is adapted to the shape of the first air outlet surface 211a, and the second guide structure 11112b is adapted to the shape of the second air outlet surface 212a. That is, the shapes of the first guide structure 11112a and the second guide structure 11112b are also curved, so that the air outlet channel defined together with the air outlet surface is smoother and the airflow is better guided through.

[0291] By matching the shape of the first air guide structure 11112a with the shape of the first air outlet surface 211a of the volute tongue 211 and the shape of the first air guide structure 11112a with the shape of the second air outlet surface 212a of the volute 212, the air guide structure and the air outlet surface can be made to be roughly consistent. While guiding the airflow to the air outlet, it can reduce eddies and noise, resulting in a better air intake effect.

[0292] In some embodiments, the first flow guiding structure 11112a and the second flow guiding structure 11112b can be independently configured components, but this would increase the number of parts and make assembly difficult.

[0293] Therefore, in some embodiments, see Figure 15 and Figure 16 The panel 111 includes an inner panel 1111, which is disposed opposite to the air duct structure 20. The inner panel 1111 includes a first flow guiding structure 11112a and a second flow guiding structure 11112b, such that the first flow guiding structure 11112a and the second flow guiding structure 11112b constitute part of the inner panel 1111. By incorporating the first flow guiding structure 11112a and the second flow guiding structure 11112b as part of the inner panel 1111 and integrally disposed with it, the number of parts is reduced, and assembly is facilitated in one step.

[0294] As mentioned above, the shapes of the first airflow guiding structure 11112a, the second airflow guiding structure 11112b, the first air outlet surface 211a, and the second air outlet surface 212a are compatible. Optionally, the overall shapes of the first airflow guiding structure 11112a and the second airflow guiding structure 11112b are compatible, that is, the two opposite surfaces of the first airflow guiding structure 11112a and the second airflow guiding structure 11112b are curved surfaces. Compared to the setting where only the side of the first airflow guiding structure 11112a and the second airflow guiding structure 11112b facing the first air outlet surface 211a and the second air outlet surface 212a is curved, this can save materials and make the panel 111 thinner while guiding the airflow.

[0295] For aesthetic purposes, in some embodiments, the panel 111 includes an outer panel 1112 connected to the inner panel 1111 to cover at least a portion of the inner panel 1111, and the outer panel 1112 is provided with a third air outlet 104.

[0296] It is understandable that the outer panel 1112 is a decorative panel 111 that faces the user and serves as the main exterior surface.

[0297] The panel 111 is designed to include an inner panel 1111 and an outer panel 1112. The first flow guiding structure 11112a and the second flow guiding structure 11112b are formed as part of the inner panel 1111. There is no need to set up an additional flow guiding structure. The flow guiding structure is formed by the structure of the inner panel 1111 itself. This can reduce the number of parts of the panel 111, so as to facilitate the installation of the panel 111. It also simplifies the structure of the panel 111 and is more conducive to the thinning of the panel 111.

[0298] Furthermore, since the first airflow guiding structure 11112a and the second airflow guiding structure 11112b are set at an angle and constitute part of the inner panel 1111, the front side of the inner panel 1111 near the user is not a flat surface. For aesthetic purposes, the outer panel 1112 is connected to the inner panel 1111 to cover at least part of the inner panel 1111, serving as the appearance surface of the panel 111, thereby improving the aesthetics of the casing 10.

[0299] In some embodiments, combined with Figure 17 The inner plate 1111 also includes a first connecting plate portion 11112c, which is connected between the first side plate 112 and the first flow guiding structure 11112a.

[0300] In some embodiments, the inner plate 1111 further includes a second connecting plate portion 11112d, which is connected between the second side plate 113 and the second flow guiding structure 11112b.

[0301] It should be noted that the first connecting plate portion 11112c and the second connecting plate portion 11112d can serve as transition portions. The wall thickness of both gradually increases from the connection point with the flow guiding structure toward the side plate, making the transition between the flow guiding structure and the side plate smoother, so as to ensure structural strength and avoid stress concentration.

[0302] This configuration ensures reliable connection between the first flow guiding structure 11112a and the second flow guiding structure 11112b and the first side plate 112 and the second side plate 113, respectively.

[0303] In some embodiments, the inner panel 1111 can extend from the top of the outer panel 1112 to the bottom of the outer panel 1112 along the height direction Z of the housing. That is, the heights of the inner panel 1111 and the outer panel 1112 are approximately the same, so that the outer panel 1112 can completely cover the inner panel 1111 from top to bottom without forming gaps on the main appearance surface and affecting the appearance.

[0304] In some embodiments, combined with Figure 16 The inner panel 1111 includes a first part 11111, which has an opening that is connected to the third air outlet 104.

[0305] In some embodiments, the inner panel 1111 includes a second portion 11112, which is connected to the first portion 11111 and is located below the first portion 11111 along the height direction Z of the housing. The second portion 11112 includes a first airflow guiding structure 11112a and a second airflow guiding structure 11112b. The first air outlet 102 and the second air outlet 103 both extend from one end of the second portion 11112 to the other end along the height direction Z of the housing.

[0306] By dividing the inner panel 1111 into upper and lower parts, the upper first part 11111 forms an opening connecting to the third air outlet 104, allowing unheated air from the second air duct 201b to be blown out from the upper third air outlet 104. The lower second part 11112 forms a first guide structure 11112a and a second guide structure 11112b, and the extension lengths of the second air outlet 103 and the third air outlet 104 are approximately the same as the height of the second part 11112. That is, the first air outlets located on both sides of the casing 10... The air vent 102, the second air outlet 103, and the third air outlet 104 located on the front side of the casing 10 are staggered in the height direction Z of the casing. This avoids the air from the air outlets in the vertical direction from interfering with each other, causing the air conditioning air and ambient air to mix and resulting in poor cooling effect. As a result, the air conditioning air blown out by the first air outlet 102 and the second air outlet 103 lowers the indoor temperature, and the ambient air blown out by the third air outlet 104 prevents the indoor temperature from becoming too low, thus achieving a "cool but not cold" feeling effect.

[0307] In some embodiments, the outer panel 1112 and the inner panel 1111 are spaced apart in the third direction X. This prevents the outer panel 1112 from being too thick and heavy in order to fit the first flow guiding structure 11112a and the second flow guiding structure 11112b of the inner panel 1111. This saves materials and reduces production costs while still being able to shield the inner panel 1111.

[0308] With the gap between the inner panel 1111 and the outer panel 1112, the outer panel 1112 is highly susceptible to deformation. To reduce the risk of deformation of the outer panel 1112, in some embodiments, the panel 111 further includes a support member (not shown). The support member is disposed between the outer panel 1112 and the inner panel 1111, and is configured to support the outer panel 1112. By providing a support member between the inner panel 1111 and the outer panel 1112, support can be provided to the outer panel 1112, thereby strengthening the structural strength of the outer panel 1112 and preventing excessive deformation.

[0309] See Figure 12 In some embodiments, one of the inner plate 1111 and the outer plate 1112 is provided with a hook 1112a, and the other of the inner plate 1111 and the outer plate 1112 is provided with a slot 1111a. The hook 1112a and the slot 1111a are engaged and connected. By providing a hook 1112a or a slot 1111a between the inner plate 1111 and the outer plate 1112, the inner plate 1111 can provide a certain support for the outer plate 1112 while still enabling the connection between the outer plate 1112 and the inner plate 1111, thereby improving the connection reliability of the outer plate 1112.

[0310] For example, the inner plate 1111 is provided with a slot 1111a, and the outer plate 1112 is provided with a hook 1112a. The hook 1112a is engaged with the slot 1111a to connect the outer plate 1112 and the inner plate 1111.

[0311] In some embodiments, a support member, a hook 1112a, and a slot 1111a are provided between the outer plate 1112 and the inner plate 1111. In this way, a reliable connection between the outer plate 1112 and the inner plate 1111 can be achieved, while the support of the outer plate 1112 can be effectively strengthened, thereby improving the structural stability of the outer plate 1112.

[0312] In some embodiments, the front shell 11 may also include a decorative ring 114, which may be disposed on the outer panel 1112 and surround the outer periphery of the third air outlet 104 to serve a decorative purpose and to protect the edge of the third air outlet 104, thereby avoiding the safety hazard caused by the exposed corners of the third air outlet 104.

[0313] Combination Figure 19 In some embodiments, the height of the first fan section 33 in the height direction of the casing 10 is H, and the height of the second fan section 34 in the height direction of the casing is h, where h:H ≥ 1:5.

[0314] The height ratio of the second fan section 34 to the first fan section 33 should not be less than 1:5, meaning the height of the second fan section 34 should not be less than one-fifth of the height of the first fan section 33. If the height ratio of the second fan section 34 to the first fan section 33 is less than 1:5, the height of the second fan section 34 will be too low, affecting the air volume and outlet speed within the second air duct 201b. This will result in the airflow from the third air outlet 104 not being effectively dispersed into the room, leading to poor indoor air circulation and hindering the acceleration of airflow dispersion, thus affecting the cooling or heating effect of the air conditioner. Conversely, if the height of the first fan section 33 is too high, it will compress the space of the first air duct 201a, causing the third air outlet 104 to be positioned closer to the top of the casing. This will limit the airflow range of the third air outlet and result in excessive air volume and speed from the first fan section 33. This airflow will be blown onto the user before mixing with the air from the third air outlet 104, affecting the effectiveness of the second fan section 34. Therefore, satisfying this relationship ensures that the first fan section 33 is not too high and the second fan section 34 is not too low, thus ensuring that both the first fan section 33 and the second fan section 34 have reasonable air volume. This ensures that the air conditioning air blown out by the first fan section 33 has a cooling effect on the room, while also ensuring that the ambient air blown out by the second fan section 34 increases the air flow efficiency of the room and improves the air circulation effect.

[0315] In some embodiments, the height of the first fan section 33 in the height direction Z of the casing 10 is H, and the height of the second fan section 34 in the height direction of the casing is h, where h:H≤1:2.

[0316] The height ratio of the second fan section 34 to the first fan section 33 should not exceed 1:2, meaning the height of the second fan section 34 cannot exceed half the height of the first fan section 33. If the height ratio of the second fan section 34 to the first fan section 33 is greater than 1:2, the second fan section 34 is too tall, excessively occupying the upper space of the air conditioner, resulting in an unreasonable positive electrode layout. Since the main function of the air conditioner is to blow out cooling or heating air, the airflow of the first fan section 33 should be sufficiently large. If the height of the second fan section 34 is greater than half that of the first fan section 33, when the unheated ambient air is blown out of the second duct, the excessive airflow will mix with the cooling air blown out of the first duct, reducing the cooling or heating effect, affecting the air conditioning performance, and increasing energy consumption. Satisfying this relationship maintains a reasonable airflow ratio between the first fan section 33 and the second fan section 34 and a reasonable spatial layout of the air conditioner, ensuring that the performance of the air conditioner does not degrade.

[0317] In some embodiments, the height of the first fan section 33 in the height direction Z of the casing 10 is H, and the height of the second fan section 34 in the height direction of the casing is h, where 1:5 ≤ h:H ≤ 1:2. For example, h:H can satisfy 1:5 ≤ h:H ≤ 1:3, 1:4 ≤ h:H ≤ 1:2, or 1:4 ≤ h:H ≤ 1:3, etc. Exemplarily, h:H can be 1:2, 1:3, or 1:4, etc.

[0318] The height ratio of the second fan section 34 to the first fan section 33 satisfies 1:5≤h:H≤1:2, which can reasonably control the air volume of the first fan section 33 and the second fan section 34. While effectively ensuring the cooling effect of the first fan section 33, the air volume of the second fan section 34 can drive the flow of indoor air and quickly disperse it, so that the indoor temperature brings a more comfortable feeling to the human body.

[0319] In some embodiments, the diameter of the first fan section 33 is D, and the diameter of the second fan section 34 is d, where d:D ≥ 1:2.

[0320] The diameter ratio of the second fan section 34 to the first fan section 33 should be no less than 1:2, meaning the diameter of the second fan section 34 cannot be less than half the diameter of the first fan section 33. If the diameter ratio is less than 1:2, the diameter of the second fan section 34 will be too small, affecting the airflow of the second duct. Insufficient airflow will fail to meet the indoor airflow requirements, causing the air conditioning air blown out through the first duct to not disperse quickly, resulting in a large indoor temperature gradient and affecting the user experience. Furthermore, small-diameter fans often need to operate at high speeds to compensate for insufficient airflow, which generates high operating noise and affects the user experience. Therefore, by setting the diameter ratio of the second fan section 34 to the first fan section 33 to be greater than 1:2, the diameter of the second fan section 34 is ensured to be sufficient, guaranteeing the airflow and delivery distance of the second fan section 34. This ensures effective indoor air circulation and provides users with a better perceived temperature.

[0321] In some embodiments, the diameter of the first fan section 33 is D, and the diameter of the second fan section 34 is d, where d:D ≤ 1:1.

[0322] The diameter ratio of the second fan section 34 to the first fan section 33 shall not exceed 1:1, that is, the diameter of the second fan section 34 shall not be greater than the diameter of the first fan section 33. If the diameter ratio of the second fan section 34 to the first fan section 33 is greater than 1:1, the diameter of the second fan section 34 is too large, resulting in excessive wind speed and air volume, increasing the energy consumption of the air conditioner, and may also cause the airflow blown out from the second air duct to be too concentrated in the upper area, affecting the uniformity and comfort of the overall indoor airflow.

[0323] In some embodiments, the diameter of the first fan section 33 is D, and the diameter of the second fan section 34 is d, where 1:2 ≤ d:D ≤ 1:1. For example, d:D can satisfy 1:1.5 ≤ d:D ≤ 1:1, 1:1.2 ≤ d:D ≤ 1:1, or 1:2 ≤ d:D ≤ 1:1.2, etc. Exemplarily, d:D can be 1:1, 2:3, or 1:2, etc.

[0324] The diameter ratio of the second fan section 34 and the first fan section 33 satisfies 1:2≤d:D≤1:2, which makes the air volume of the two fan sections more balanced. The air volume of the first fan section 33 lowers the indoor temperature, while the air volume of the second fan section 34 can achieve long-distance delivery and drive indoor air circulation. It also makes the airflow more stable, does not generate much noise, and reduces the energy consumption of the air conditioner.

[0325] In this embodiment, by limiting the size ratio of the first fan section 33 and the second fan section 34 to a reasonable range, the noise of the cross-flow fan is reduced while ensuring airflow, thus improving user comfort. Furthermore, this ensures a reasonable layout of the first fan section 33 and the second fan section 34, preventing performance degradation and enhancing the aesthetic appearance of the indoor unit 100. An excessively large second fan section 34 results in high noise levels and a poor user experience; an excessively small second fan section 34 leads to low airflow and short delivery distance, affecting user comfort.

[0326] It is understandable that when the fan includes the first cross-flow fan 31 and the second cross-flow fan 32, the size relationship between the two can also refer to the design of the first fan section 33 and the second fan section 34, and the details will not be elaborated further.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the vertical air conditioner and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
