Description

Technical Field

[0001] This application relates to the field of air handling technology, and more particularly to an indoor air conditioning unit. Background Technology

[0002] An air conditioner is a device that uses a refrigeration cycle to control the temperature, humidity, and airflow distribution of an indoor room. Air conditioners can be independent split-type units with indoor and outdoor units installed separately.

[0003] In applications where a single indoor air conditioning unit provides cooling / heating to multiple rooms throughout a house, the unit's air outlet connects to a main duct. This main duct then connects to multiple branch ducts via a distribution box, with the branches connecting to individual rooms. Air is supplied to each room via the main duct, distribution box, and branch ducts. However, for typical small homes, such as living rooms, dining rooms, and bedrooms, this structural design suffers from complex ductwork and high costs. Summary of the Invention

[0004] This application provides an indoor air conditioning unit that can achieve whole-house air conditioning at a low cost.

[0005] An indoor unit for an air conditioner includes a housing with a first air outlet and a second air outlet. One of the first and second air outlets is used to communicate with a dynamic indoor zone, and the other is used to communicate with a quiet indoor zone. Multiple first and / or second air outlets are included. A fan, disposed within the housing, is used to drive airflow. A heat exchanger, disposed on the air outlet side of the fan, is used to exchange heat with the air driven by the fan. A first air valve is used to control the connection or disconnection of air to the first air outlet. When the first air valve is open, the fan causes air passing through the heat exchanger to flow through the first air valve to the first air outlet. A second air valve is used to control the connection or disconnection of air to the second air outlet. When the second air valve is open, the fan causes air passing through the heat exchanger to flow through the second air valve to the second air outlet.

[0006] In this technical solution, multiple air outlets are set on the casing, which can deliver air to the indoor dynamic zone or the indoor quiet zone accordingly. It can achieve whole-house multi-room air conditioning without the need for a distribution box and main air duct, which simplifies the structure of the air duct when installing and using the air conditioner indoor unit and reduces costs.

[0007] The air outlets are divided into first air outlets and second air outlets, which are connected to the quiet zone and the active zone of the room, respectively. Then, the first air valve controls the flow of air to all first air outlets, and the second air valve controls the flow of air to all second air outlets. This allows for separate air supply to the quiet and active zones, meets the user's daily usage habits, and reduces the number of air valves used, thus lowering costs.

[0008] In some embodiments, the heat exchanger is located on the air outlet side of the fan; the heat exchanger includes a heat exchange body and end plates connected to both ends of the heat exchange body; the space between the heat exchange body and the air inlet of the air outlet cavity forms a downstream heat exchange region, and the air passing through the heat exchange body flows to the air outlet cavity through the downstream heat exchange region.

[0009] In this technical solution, by providing a downstream heat exchange area between the air inlet end of the air outlet cavity and the heat exchanger body, when the first or second air valve is closed, all the air that has undergone heat exchange through the heat exchanger can flow to the open air valve through the downstream heat exchange area, and the heat exchange air volume will not be reduced, thereby ensuring the working capacity of the air conditioner; the spacing between the air inlet side of the air outlet cavity and the heat exchange core can expand the space volume between the air valve and the heat exchanger, and reduce the wind resistance in this area.

[0010] In some embodiments, the indoor unit of the air conditioner further includes: a damper bracket disposed on the side of the air outlet cavity near the main air duct; the damper bracket includes a first damper bracket and a second damper bracket distributed along its length direction; the fan and the heat exchanger are arranged in a first direction, and the length direction of the damper bracket is perpendicular to the first direction; the first damper bracket forms the air inlet side cavity wall of the first air outlet cavity, and the first damper is connected to the first damper bracket; the second damper bracket forms the air inlet side cavity wall of the second air outlet cavity, and the second damper is connected to the second damper bracket.

[0011] In this technical solution, a valve bracket is used to install and fix the valve.

[0012] In some embodiments, the middle part of the damper bracket protrudes into the air outlet cavity from its two ends, so that an upstream region of the air outlet cavity is formed between the damper bracket and the air inlet end of the air outlet cavity. When the first air valve is in the open state and the second air valve is in the closed state, the air passing through the main air duct flows to the first air outlet chamber through the upstream area of ​​the air outlet chamber; When the second air valve is open and the first air valve is closed, the air passing through the main air duct flows to the second air outlet chamber via the upstream area of ​​the air outlet chamber.

[0013] In this technical solution, by designing the middle part of the damper bracket to protrude into the air outlet cavity, the space between the damper bracket and the heat exchanger is further expanded, thereby reducing the air resistance in this space. Furthermore, the fact that the middle part of the damper bracket protrudes into the air outlet cavity compared to its ends gives the damper bracket a guiding function, further reducing air resistance.

[0014] In some embodiments, the first air valve bracket includes: a first support portion, to which a first air valve is connected; and a first fixing portion, connected to the end of the first support portion away from the second air valve bracket, wherein the surface of the first fixing portion opposite to the first air outlet cavity abuts against the end plate of the heat exchanger on the same side; the second air valve bracket includes: a second support portion, to which a second air valve is connected; and a second fixing portion, connected to the end of the second support portion away from the first air valve bracket, wherein the surface of the second fixing portion opposite to the second air outlet cavity abuts against the end plate of the heat exchanger on the same side.

[0015] In this technical solution, by setting the fixing part of the air valve bracket to abut against the end plate of the heat exchanger, the problem of air spreading into the gap between the two and increasing air resistance is avoided.

[0016] In some embodiments, a partition is provided inside the air outlet cavity to separate the first air outlet cavity and the second air outlet cavity; the partition is connected to the middle part of the air valve bracket in the length direction.

[0017] In some embodiments, the first air valve and the second air valve are also referred to as air valves. The air valve includes: an air valve outer frame on which a ventilation cavity is formed; a plurality of swing blades arranged along the height direction, the swing blades being rotatably connected to the ventilation cavity; when the air valve is in the closed state, the plurality of swing blades cover the ventilation cavity; when the air valve is in the open state, the swing blades open the ventilation cavity.

[0018] In this technical solution, the air valve adopts a multi-blade structure, which can reduce the space occupied by the air valve, thereby reducing wind resistance and increasing the air volume.

[0019] In some embodiments, the indoor unit of the air conditioner further includes: a first air outlet flange, connected to the outside of the housing corresponding to the first air outlet, for connection to the air duct; the ventilation cross-sectional area of ​​the first air valve is not less than the sum of the ventilation cross-sectional areas of all the first air outlet flanges; a second air outlet flange, connected to the outside of the housing corresponding to the second air outlet, for connection to the air duct; the ventilation cross-sectional area of ​​the second air valve is not less than the sum of the ventilation cross-sectional areas of all the second air outlet flanges.

[0020] In this technical solution, by limiting the ventilation cross-sectional area of ​​the first air valve and the ventilation cross-sectional area of ​​the second air valve, the air resistance when air passes through the air valve can be reduced.

[0021] In some embodiments, the housing includes: a main unit housing, on which an air inlet and a main unit air outlet are provided, the air inlet and the main unit air outlet being connected to form a main air duct; and an air outlet housing, which is connected to the outside of the main unit housing corresponding to the main unit air outlet, and a first air outlet and a second air outlet are provided on the air outlet housing.

[0022] In this technical solution, the housing is a two-part structure consisting of a main unit housing and an air outlet housing, which allows the air outlet housing and its internal parts to be used as optional accessories, thereby expanding the application range of the air conditioning indoor unit.

Detailed Implementation

[0025] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0026] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0030] The compressor compresses refrigerant gas at a low temperature and low pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0031] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0032] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0033] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0034] This application relates to an indoor unit for air conditioning an indoor space. In the following text, for convenience, the indoor unit including an indoor heat exchanger is referred to as an air conditioning indoor unit, and the indoor heat exchanger is referred to as a heat exchanger.

[0035] The following is a reference to the appendix. Figures 1-14 The implementation methods of this application will be described in detail.

[0036] Refer to 1 to Figure 3 The indoor unit of the air conditioner according to the embodiments of this application can be a ceiling-mounted duct air conditioner, but the embodiments of this application are not limited to this.

[0037] The indoor unit of the air conditioner includes a housing 10. The housing 10 is generally rectangular in shape, forming the overall appearance of the indoor unit. The housing 10 may include a top plate forming the top appearance, a bottom plate forming the bottom appearance, and side plates connecting the top plate and the bottom plate.

[0038] The top panel, bottom panel, and / or side panel can be a single piece of panel, or they can be made up of multiple panels joined together.

[0039] The side panels are a first side panel 11 and a second side panel 12 arranged opposite to each other, and a third side panel 13 and a fourth side panel 14 arranged opposite to each other. The third side panel 13 and the fourth side panel 14 are arranged in the first direction X, the first side panel 11 and the second side panel 12 are arranged in the second direction Y, and the top and bottom panels are arranged in the height direction Z.

[0040] The housing 10 may include an air inlet 10a through which indoor air is drawn in. The air inlet 10a may be formed by opening at least a portion of a side panel. Exemplarily, the air inlet 10a may be located on a fourth side panel 14. In other embodiments, the air inlet 10a may be formed by opening a portion of the bottom plate near the fourth side panel 14.

[0041] The housing 10 may include an air outlet 10b, through which air introduced through the air inlet 10a undergoes heat exchange within the housing 10 and is then discharged into the indoor space.

[0042] The indoor unit of the air conditioner includes a fan 20, which is disposed inside the housing 10 and located on the air movement path from the air inlet 10a to the air outlet 10b, and is used to drive airflow. The fan 20 can be a centrifugal fan.

[0043] The fan 20 includes a fan. The fan includes an impeller and a volute casing covering the impeller. The axis of the impeller extends along a second direction Y. The impeller has a disk and a plurality of blades spaced apart along the outer periphery of the disk. Two opposite sides of the volute casing are arranged along the second direction Y, and fan intake ports are formed on these two side surfaces. The fan exhaust ports of the volute casing face the third side plate 13.

[0044] The fan 20 includes a fan motor connected to the impeller, which is energized to provide rotational force to the impeller. The fan motor may be located outside the volute and connected to the housing 10.

[0045] There may be multiple fans. In the example at that time, there were two fans, which were arranged at a distance along the second direction Y, and the fan motor was located between the two fans.

[0046] The indoor unit of the air conditioner includes a heat exchanger 30. The heat exchanger 30 is disposed inside the housing 10 and located on the air movement path from the air inlet 10a to the air outlet 10b, and is used to exchange heat with the air passing through it.

[0047] The heat exchanger 30 includes refrigerant pipes through which refrigerant flows and fins connected to the refrigerant pipes to increase the heat exchange area. A drip tray 31 may be disposed below the heat exchanger 30 to collect moisture condensed in the heat exchanger 30. The drip tray 31 may be connected to a drain pipe connected to the outside of the housing 10 and can discharge condensed moisture to the outside of the housing 10.

[0048] The heat exchanger 30 extends along the second direction Y. The heat exchanger 30 can be V-shaped with its opening facing the fourth side plate 14. Compared with a straight plate heat exchanger 30, it can increase the heat exchange area and improve the heat exchange efficiency in a limited space, thereby improving the cooling / heating capacity of the air conditioner.

[0049] In the current example, the fan 20 is positioned near the air inlet 10a, and the heat exchanger 30 is positioned on the air outlet side of the fan 20. A duct baffle 15 is provided inside the housing 10. The duct baffle 15 is positioned between the fan 20 and the heat exchanger 30, and a duct vent can be provided on the duct baffle 15. The exhaust portion of the fan 20's volute passes through the duct vent, so that the exhaust air from the fan 20 is blown towards the heat exchanger 30.

[0050] In other embodiments, the fan may be a cross-flow fan extending along the second direction Y in the longitudinal direction. The cross-flow fan may be located on the leeward side of the heat exchanger 30, that is, the heat exchanger 30 is located near the air inlet 10a, and the cross-flow fan is located between the fan 20 and the air outlet 10b.

[0051] In the embodiments of this application, there may be multiple air outlets 10b, and each air outlet 10b is connected to a different room through an air duct, so as to realize that the indoor unit of the air conditioner delivers air to multiple rooms throughout the house.

[0052] An air outlet flange 40 can be installed at the air outlet 10b for connection to the air duct. The air outlet flange 40 is connected to the outer side of the housing 10 corresponding to the air outlet 10b.

[0053] In a home application scenario, the air conditioner is used to regulate all rooms in the house. Taking a house with four rooms as an example, the air outlet 10b of the indoor unit of the air conditioner can be set to at least four, with each of the four air outlets 10b corresponding to one of the four rooms.

[0054] In some embodiments, a damper is provided at each air outlet 10b, which controls the opening and closing of the corresponding air outlet 10b. This structure can meet the need for whole-house air supply by a single indoor air conditioning unit. However, this inevitably requires a large number of dampers and more complex control logic to control the opening and closing of each damper, resulting in a higher cost for the air conditioner. For small, ordinary families with tight budgets, this type of air conditioner is expensive.

[0055] In order to achieve both the goal of supplying air to the whole house from a single indoor air conditioning unit and reducing the cost of air conditioners, this application divides rooms into active and quiet zones according to the time periods users typically spend in each room. For example, people spend most of their time in the living room during the day, so the living room can be classified as the active zone, where air conditioning is generally used during the day; people spend most of their time resting in the bedroom at night, so the bedroom can be classified as the quiet zone, where air conditioning is generally used at night.

[0056] In some embodiments of this application, among the plurality of air outlets 10b, at least one air outlet 10b is a first air outlet 10c, and at least one air outlet 10b is a second air outlet 10d. The first air outlet 10c is used to communicate with the indoor active zone, and the second air outlet 10d is used to communicate with the indoor quiet zone; or the first air outlet 10c is used to communicate with the indoor quiet zone, and the second air outlet 10d is used to communicate with the indoor active zone.

[0057] The air outlet 10b has at least three outlets, wherein at least one air outlet 10b is a first air outlet 10c and at least two air outlets 10b are second air outlets 10d; or, at least one air outlet 10b is a second air outlet 10d and at least two air outlets 10b are first air outlets 10c.

[0058] In the current example, there are four first air outlets 10c and four second air outlets 10d, which can meet the usage needs of up to four indoor active zone rooms and four indoor quiet zone rooms throughout the house.

[0059] For scenarios where there are fewer than four active and / or quiet rooms in the entire house, for example, based on the user's usage time of the rooms, only the living room is an active indoor area used more during the day, while the other three rooms are quiet indoor areas used at night, taking the first air outlet 10c to supply air to the active indoor area and the second air outlet 10d to supply air to the quiet indoor area as an example, then the ducts of all four first air outlets 10c can be connected to the air outlet of the living room; the ducts of the three second air outlets 10d can be connected to the three quiet room respectively; and the remaining second air outlet 10d can be connected to the larger quiet room, the room with the longer usage time, or any other connection.

[0060] In other embodiments, a knockdown plate design can be used at the air outlet 10b. During on-site installation and use, the knockdown plate at the used air outlet 10b is knocked off, while the knockdown plate at the unused air outlet 10b is retained, thus sealing the air outlet 10b. Again, taking a room with one active zone and three quiet zones as an example, of the four first air outlets 10c, the knockdown plate at one of the first air outlets 10c is knocked off, and this first air outlet 10c is connected to the active zone via a duct. The knockdown plates at the other three first air outlets 10c are retained and do not require duct connection. Of the four second air outlets 10d, the knockdown plates at three of the second air outlets 10d are knocked off, and each is connected to one of the three quiet zones via a duct. The knockdown plate at the remaining second air outlet 10d is retained and does not require duct connection.

[0061] In some embodiments, the indoor unit of the air conditioner includes two air valves 50, namely a first air valve 501 and a second air valve 502. The first air valve 501 is used to control the connection or disconnection of air to the first air outlet 10c, and the second air valve 502 is used to control the connection or disconnection of air to the second air outlet 10d.

[0062] Reference Figure 4 The arrows in the diagram indicate the airflow direction. When the user only needs the air conditioning to adjust the air in the active indoor zone, the first air valve 501 opens and the second air valve 502 closes, allowing air to be supplied to the active indoor zone from the first air outlet 10c; see reference. Figure 5 The arrows in the diagram indicate the airflow direction. When the user only needs the air conditioner to regulate the air in the quiet zone of the room, the first air valve 501 is closed and the second air valve 502 is opened, and air is delivered to the quiet zone of the room from the second air outlet 10d. When the user needs the air conditioner to regulate the air in both the active and quiet zones of the room at the same time, both the first air valve 501 and the second air valve 502 are open.

[0063] In this application, the air outlet 10b is divided into a first air outlet 10c and a second air outlet 10d according to the indoor dynamic zone and the indoor static zone. The first air valve 501 controls whether the first air outlet 10c sends air to the dynamic zone, and the second air valve 502 controls whether the second air outlet 10d sends air to the static zone. This realizes the zoned air supply of the dynamic zone and the static zone, meets the requirement that the indoor unit of the air conditioner can supply air to multiple rooms in the whole house, and reduces the number of air valves 50 used, thereby reducing the cost and expanding the application range of the air conditioner.

[0064] In some embodiments, refer to Figure 4 , Figure 5 The housing 10 is provided with a main air duct 101, and the fan 20 and heat exchanger 30 are both located inside the main air duct 101.

[0065] In the embodiment where the heat exchanger 30 is located on the air outlet side of the fan 20, the air inlet 10a and the leeward end of the heat exchanger 30 are connected to form a main air duct 101, and the air flows through the fan 20 and the heat exchanger 30 in sequence within the main air duct 101.

[0066] In an embodiment where the fan 20 is located on the leeward side of the heat exchanger 30, the air inlet 10a and the fan exhaust outlet are connected to form a main air duct 101.

[0067] The first air valve 501 is located on the airflow path between the main air duct 101 and the first air outlet 10c, and is used to control the connection or disconnection between the main air duct 101 and the first air outlet 10c.

[0068] When the first air valve 501 is in the open state, the main air duct 101 is connected to the first air outlet 10c; when the first air valve 501 is in the closed state, the main air duct 101 is disconnected from the first air outlet 10c.

[0069] The second air valve 502 is located on the airflow path between the main air duct 101 and the second air outlet 10d, and is used to control the connection or disconnection between the main air duct 101 and the second air outlet 10d. When the second air valve 502 is in the open state, the main air duct 101 is connected to the second air outlet 10d; when the second air valve 502 is in the closed state, the main air duct 101 is disconnected from the second air outlet 10d.

[0070] In some embodiments, assuming a plane S is perpendicular to the second direction Y, the first air outlet 10c and the second air outlet 10d are located on both sides of the plane S, so that the first air outlet 10c and the second air outlet 10d do not intersect in the layout, which facilitates the setting of the first air valve 501 corresponding to all the first air outlets 10c and the second air valve 502 corresponding to all the second air outlets 10d.

[0071] In some embodiments, refer to Figure 6The housing 10 has an air outlet cavity 102 located on the air outlet side of the main air duct 101. The air outlet cavity 102 includes a first air outlet cavity 103 and a second air outlet cavity 104 that are separated from each other. The first air outlet cavity 103 is connected to the first air outlet 10c, and the second air outlet cavity 104 is connected to the second air outlet 10d.

[0072] The first air valve 501 is used to open or close the first air outlet chamber 103, and the second air valve 502 is used to open or close the second air outlet chamber 104.

[0073] In this application, by setting a first air outlet cavity 103 and a second air outlet cavity 104, the first air outlet cavity 103 is opened and closed by the first air valve 501 and the second air outlet cavity 104 is opened and closed by the second air valve 502, thereby realizing the control of multiple air outlets 10b by one air valve 50, thereby reducing the number of air valves 50 used and reducing costs.

[0074] In some embodiments, a first air valve 501 is disposed on the side of the first air outlet cavity 103 near the main air duct 101, and is used to control the connection or disconnection between the first air outlet cavity 103 and the main air duct 101. When the first air valve 501 is in the open state, the main air duct 101 is connected to the first air outlet cavity 103 through the first air valve 501, and the air in the main air duct 101 flows through the first air valve 501 and the first air outlet cavity 103 to the first air outlet 10c, and then flows from the first air outlet 10c to the indoor dynamic zone; when the first air valve 501 is in the closed state, the first air valve 501 disconnects the main air duct 101 from the first air outlet cavity 103, and the indoor unit of the air conditioner does not send air to the indoor dynamic zone.

[0075] The second air valve 502 is located on the side of the second air outlet cavity 104 near the main air duct 101, and is used to control the connection or disconnection between the second air outlet cavity 104 and the main air duct 101. When the second air valve 502 is in the open state, the main air duct 101 is connected to the second air outlet cavity 104 through the second air valve 502, and the air in the main air duct 101 flows through the second air valve 502 and the second air outlet cavity 104 to the second air outlet 10d, and then flows from the second air outlet 10d to the quiet indoor area; when the second air valve 502 is in the closed state, the second air valve 502 disconnects the main air duct 101 from the second air outlet cavity 104, and the indoor unit of the air conditioner does not send air to the quiet indoor area.

[0076] In some embodiments, continue to refer to Figure 3 First air outlets 10c can be respectively set on the cavity walls of the first air outlet cavity 103 in different directions.

[0077] The third side plate 13 is provided with a first air outlet 10c, and the portion of the first side plate 11 near the third side plate 13 is also provided with a first air outlet 10c. The side plates of the housing 10 in different directions are all provided with first air outlets 10c. This allows the first air outlet 10c to be selected for ductwork installation according to actual working conditions. For example, if the ductwork installation from the first air outlet 10c on the third side plate 13 to a moving indoor area is more convenient than that from the first air outlet 10c on the first side plate 11, then the moving indoor area can be connected to the first air outlet 10c on the third side plate 13. If the ductwork installation from the first air outlet 10c on the first side plate 11 to a moving indoor area is more convenient than that from the first air outlet 10c on the third side plate 13, then the moving indoor area can be connected to the first air outlet 10c on the first side plate 11.

[0078] In some embodiments, second air outlets 10d may be respectively provided on the cavity walls of the second air outlet cavity 104 in different directions.

[0079] The third side plate 13 is provided with a second air outlet 10d. The second side plate 12 is provided with a second air outlet 10d on the part near the third side plate 13. The side plates of the housing 10 in different directions are provided with second air outlets 10d. In this way, the air duct can be laid out according to the actual working conditions by selecting the second air outlet 10d, which increases the convenience of the air duct laying connected to the second air outlet 10d.

[0080] In other embodiments, all first air outlets 10c are disposed on the third side plate 13, or all first air outlets 10c are disposed on the first side plate 11. All second air outlets 10d are disposed on the third side plate 13, or all second air outlets 10d are disposed on the first side plate 11.

[0081] In some embodiments, the air outlet cavity 102 and the main air duct 101 are arranged in a first direction X, and the first air outlet cavity 103 and the second air outlet cavity 104 are arranged in a second direction Y.

[0082] Projected in a direction perpendicular to the plane where the air outlet of the main air duct 101 is located, the first air outlet cavity 103 partially overlaps with the main air duct 101, and the second air outlet cavity 104 overlaps with the other part of the main air duct 101.

[0083] In some embodiments, the air outlet cavity 102 is provided with a partition 16, which divides the air outlet cavity 102 into a first air outlet cavity 103 and a second air outlet cavity 104.

[0084] In the second direction Y, the first air valve 501 and the second air valve 502 are located on both sides of the partition plate 16, respectively.

[0085] In the related technology, the first part of the heat exchanger 30 is connected to the first air outlet cavity 103, and the second part of the heat exchanger 30 is connected to the second air outlet cavity 104. Air passing through the first part of the heat exchanger 30 enters the first air outlet cavity 103, and air passing through the second part of the heat exchanger 30 enters the second air outlet cavity 104. When the first air outlet cavity 103 is connected to the main air duct 101, and the second air outlet cavity 104 is not connected to the main air duct 101, only the air that has exchanged heat with the first part of the heat exchanger 30 can continue to flow to the first air outlet cavity 103; when the first air outlet cavity 103 is not connected to the main air duct 101, and the second air outlet cavity 104 is connected to the main air duct 101, only the air that has exchanged heat with the second part of the heat exchanger 30 can continue to flow to the second air outlet cavity 104. This will greatly reduce the utilization rate of the heat exchanger 30, thereby reducing the cooling / heating capacity of the air conditioner.

[0086] In some embodiments of this application, reference is made to Figure 7 The heat exchanger 30 includes a heat exchange body 301. End plates are connected to both ends of the heat exchange body 301 along its length.

[0087] Reference Figure 6 There is a space between the heat exchange body 301 of the heat exchanger 30 and the air outlet cavity 102. This space is the downstream heat exchange region 101a of the main air duct 101. This allows the air that has undergone heat exchange with any part of the heat exchanger 30 to flow through the downstream heat exchange region 101a to the air outlet cavity 102 without reducing the utilization rate of the heat exchanger 30, thus ensuring the cooling / heating capacity of the air conditioner.

[0088] In some embodiments, a first air valve 501 is disposed on the air inlet side of the first air outlet chamber 103. A second air valve 502 is disposed on the air inlet side of the second air outlet chamber 104.

[0089] Along the direction from the end of the first air valve 501 away from the second air outlet cavity 104 to the end closer to the second air outlet cavity 104, the first air valve 501 gradually moves away from the heat exchanger 30. Along the direction from the end of the second air valve 502 away from the first air outlet cavity 103 to the end closer to the first air outlet cavity 103, the second air valve 502 gradually moves away from the heat exchanger 30.

[0090] This configuration serves two purposes: firstly, it increases the volume of space between the heat exchanger 30 and the damper 50, thereby reducing air resistance and increasing airflow; secondly, as the damper 50 gradually moves away from the heat exchanger 30, it guides airflow. When the first damper 501 is closed and the second damper 502 is open, the first damper 501 can gradually guide airflow away from the second damper 502 towards the first damper 501. Similarly, when the first damper 501 is open and the second damper 502 is closed, the second damper 502 can gradually guide airflow away from the first damper 501 towards the second damper 502, further reducing air resistance and increasing airflow.

[0091] In some embodiments, along the direction from one end of the first air valve 501 away from the second air outlet cavity 104 to the end near the second air outlet cavity 104, the first air valve 501 is inclined in a direction that reduces the size of the first air outlet cavity 103, that is, in a direction away from the heat exchanger 30. Similarly, along the direction from one end of the second air valve 502 away from the first air outlet cavity 103 to the end near the first air outlet cavity 103, the second air valve 502 is inclined in a direction that reduces the size of the second air outlet cavity 104, that is, in a direction away from the heat exchanger 30.

[0092] The first air valve 501 and the second air valve 502 are set at an angle, which can guide the airflow towards each other, reduce wind resistance, and increase the air volume of the indoor unit of the air conditioner.

[0093] In some embodiments, the tilt angle α1 of the first air valve 501 relative to the second direction Y is ≤30°. If α1>30°, the first air valve 501 occupies more space in the first direction X, which requires increasing the size of the indoor air conditioning unit, hindering the miniaturization design of the indoor air conditioning unit. α1≤30° allows for reduced wind resistance and increased airflow within the available space.

[0094] Similarly, the tilt angle α2 of the second air valve 502 relative to the second direction Y is ≤30°.

[0095] In some embodiments, refer to Figure 3 , Figure 7 and Figure 8 The damper 50 is installed inside the housing 10 via the damper bracket 60. The damper bracket 60 is located on the air inlet side of the air outlet chamber 102. The length of the damper bracket 60 extends along the second direction Y.

[0096] The first air valve 501 is installed on the air valve bracket 60 corresponding to the first air outlet chamber 103, and the second air valve 502 is installed on the air valve bracket 60 corresponding to the second air outlet chamber 104.

[0097] The damper bracket 60 includes a first damper bracket 61 and a second damper bracket 62 arranged along its length. The first damper bracket 61 forms the air inlet side cavity wall of the first air outlet cavity 103, and the second damper bracket 62 forms the air inlet side cavity wall of the second air outlet cavity 104.

[0098] In some embodiments, refer to Figures 4 to 6 The middle part of the damper bracket 60 protrudes into the air outlet cavity 102 from its two ends, so that the space between the damper bracket 60 and the air inlet end of the air outlet cavity 102 forms the upstream region 105 of the air outlet cavity. In this way, the space between the heat exchanger 30 and the damper bracket 60 can be increased, thereby reducing the air resistance of the space.

[0099] When the first air valve 501 is in the open state and the second air valve 502 is in the closed state, the air passing through the main air duct 101 flows to the first air outlet 103 through the upstream area 105 of the air outlet cavity.

[0100] When the second air valve 502 is in the open state and the first air valve 501 is in the closed state, the air passing through the main air duct 101 flows to the second air outlet 104 through the upstream region 105 of the air outlet cavity.

[0101] In some embodiments, the first damper bracket 61 and the second damper bracket 62 are arranged in a "V" shape with their open ends facing the main air duct. The V-shaped space enclosed by the first damper bracket 61 and the second damper bracket 62 is the upstream region 105 of the air outlet cavity.

[0102] The first air valve bracket 61 and the second air valve bracket 62 can guide airflow toward each other, reduce wind resistance, and increase the air volume of the indoor unit of the air conditioner.

[0103] In some embodiments, refer to Figure 7 The first air valve bracket 61 includes a first support part 612, and the first air valve 501 is connected to the first support part 612.

[0104] The second air valve bracket 62 includes a second support part 622, and the second air valve 502 is connected to the second support part 622.

[0105] The first support portion 612 gradually moves away from the heat exchanger 30 from its end away from the second air outlet cavity 104 to its end near the second air outlet cavity 104; the second support portion 622 gradually moves away from the heat exchanger 30 from its end away from the first air outlet cavity 103 to its end near the first air outlet cavity 103. The first support portion 612 and the second support portion 622 serve to guide airflow and reduce wind resistance. When the second air valve 502 is closed and the first air valve 501 is open, the second support portion 622 guides air towards the first air valve 501; when the first air valve 501 is closed and the second air valve 502 is open, the first support portion 612 guides air towards the second air valve 502.

[0106] The space between the first support part 612, the second support part 622 and the air inlet end of the air outlet cavity 102 is the upstream region 105 of the air outlet cavity.

[0107] In some embodiments, the first support portion 612 is inclined from its end away from the second air outlet cavity 104 to its end near the second air outlet cavity 104 in a direction that reduces the size of the first air outlet cavity 103, that is, in a direction away from the heat exchanger 30; the second support portion 622 is inclined from its end away from the first air outlet cavity 103 to its end near the first air outlet cavity 103 in a direction that reduces the size of the second air outlet cavity 104, that is, in a direction away from the heat exchanger 30.

[0108] The first support part 612 and the second support part 622 are inclined towards the air outlet cavity 102 from the ends away from each other to the ends closer to each other. This can guide the airflow in the direction that they are closer to each other, reduce wind resistance, and increase the air volume of the indoor unit of the air conditioner.

[0109] In some embodiments, the air outlet flange 40 connected to the first air outlet 10c is called the first air outlet flange 41, and the air outlet flange 40 connected to the second air outlet 10d is called the second air outlet flange 42.

[0110] The ventilation cross-sectional area of ​​the first air valve 501 is not less than the sum of the ventilation cross-sectional areas of all the first air outlet flanges 41, which can reduce the wind resistance at the first air valve 501 and increase the air volume delivered to the indoor dynamic zone.

[0111] The ventilation cross-sectional area of ​​the second air valve 502 is not less than the sum of the ventilation cross-sectional areas of all the second air outlet flanges 42, which can reduce the wind resistance at the second air valve 502 and increase the air volume delivered into the quiet zone of the room.

[0112] The ventilation cross-sectional area of ​​the damper 50 refers to the minimum cross-sectional area of ​​the flow path of the damper 50 when it is in the open state. The ventilation cross-sectional areas of the first air outlet flange 41 and the second air outlet flange 42 refer to the minimum cross-sectional areas of the flow path of the air outlet flange 40.

[0113] In some embodiments, the first air valve bracket 61, the second air valve bracket 62, and / or the partition plate 16 are sheet metal parts. One of the first air valve bracket 61 and the second air valve bracket 62 is bent to form the partition plate 16, and the other of the first air valve bracket 61 and the second air valve bracket 62 is connected to the partition plate 16.

[0114] For example, the partition 16 is formed by bending a first air valve bracket 61, and the second air valve bracket 62 is connected to the partition 16 by fasteners such as screws.

[0115] In some embodiments, refer to Figure 3 and Figure 7 The heat exchanger 30 has end plates at both ends along its length. The ends of the first air valve bracket 61 and the second air valve bracket 62 that are away from each other are connected to the end plates on the same side.

[0116] The two end plates are respectively provided with a first end plate 302 and a second end plate 303. In the second direction Y, the first end plate 302 is closer to the first side plate 11 than the second end plate 303, and the first air valve bracket 61 is closer to the first side plate 11 than the second air valve bracket 62. The end of the first air valve bracket 61 that is away from the second air valve bracket 62 is connected to the first end plate 302, and the end of the second air valve bracket 62 that is away from the first air valve bracket 61 is connected to the second end plate 303.

[0117] In some embodiments, in the second direction Y, one end of the end plate near the air valve bracket 60 protrudes from the heat exchange body 301, so that a heat exchange downstream region 101a is formed between the heat exchange body 301 and the air inlet end of the air outlet cavity 102.

[0118] In some embodiments, one end of the end plate near the air valve bracket 60 is bent toward the adjacent side plate to form a bent portion 304, and the edge of the bent portion 304 is connected to the side plate of the housing 10.

[0119] The first air valve bracket 61 includes a first fixing part 613. The first fixing part 613 is connected to the end of the first support part 612 that is away from the second air valve bracket 62. The plate surface of the first fixing part 613 abuts against the bent portion 304 of the first end plate 302.

[0120] The second air valve bracket 62 includes a second fixing part 623. The second fixing part 623 is connected to the end of the second support part 622 that is away from the first air valve bracket 61. The plate surface of the second fixing part 623 abuts against the bent portion 304 of the second end plate 303.

[0121] By positioning the fixing part of the damper bracket 60 against the end plate, it avoids creating a gap between them that would hinder airflow. The surface where the damper bracket 60 abuts against the end plate is the air inlet end of the air outlet chamber 102.

[0122] In some embodiments, the space between the first side plate 11 and the first end plate 302 forms a receiving space for accommodating distribution pipes, drain pumps, etc. connected to the heat exchanger 30.

[0123] The end of the first fixing part 613 is connected to the first side plate 11 of the housing 10, thereby closing one side of the accommodating space.

[0124] In some embodiments, the bent portion 304 of the second end plate 303 is connected to the second side plate 12. The second fixing portion 623 is connected to the second side plate 12 by screws.

[0125] The first air valve bracket 61 is connected to the first side plate 11. The second end plate 303 is connected to the second side plate 12.

[0131] The water collection tray insulation layer 32 can be integrally formed with the air outlet cavity insulation base plate 72. After the water collection tray 31 is installed, the installation of the air outlet cavity insulation base plate 72 is completed, thereby improving the installation efficiency of the air outlet cavity insulation base plate 72 and eliminating the need to design a positioning structure for the air outlet cavity insulation base plate 72.

[0132] In some embodiments, the indoor unit of the air conditioner includes a heat exchange and insulation top plate 33, which is disposed on the upper side of the heat exchanger 30 and attached to the top plate of the housing 10.

In the closed state, the blade surfaces of the oscillating blade 52 extend roughly vertically, and multiple oscillating blades 52 together cover the ventilation cavity. In the open state, the blade surfaces of the oscillating blade 52 are roughly perpendicular to the height direction Z, resulting in gaps between adjacent oscillating blades 52 to allow airflow.

[0162] In some embodiments, the air valve 50 is detachably connected to the air valve bracket 60, so that the air valve 50 can be removed from the air valve bracket 60 for maintenance and repair.

[0163] The damper 50 and the damper bracket 60 can be connected by a combination of hooks 81 and screws 82. This reduces the number of screws 82 used, improves the efficiency of disassembling and assembling the damper 50, and facilitates the disassembly and assembly of the damper 50.

[0164] In some embodiments, the air valve 50 is installed on the side of the air valve bracket 60 facing the air outlet cavity 102, which allows the air valve 50 to be disassembled from the air outlet cavity 102.

[0165] In some embodiments, at least one air outlet 10b is provided adjacent to the screw 82 between the air valve 50 and the air valve bracket 60, so that the air outlet 10b can serve as a maintenance port, and the screw 82 can be removed from the air outlet 10b when the air valve 50 is disassembled and assembled, and the air valve 50 can be passed through the air outlet 10b to remove the air valve 50.

[0166] In some embodiments, one end of the air valve 50 along its length is connected to the air valve bracket 60 by a hook 81, and the other end of the air valve 50 along its length is connected to the air valve bracket 60 by a screw 82. Thus, by concentrating the screws 82 at one end of the air valve 50, all screws 82 can be disassembled from a maintenance port.

[0167] In some embodiments, the first side plate 11 and the second side plate 12 of the housing 10 are also referred to as wide side plates. Screws 82 may be provided at the end of the damper 50 near the wide side plate, and hooks 81 may be provided at the end of the damper 50 away from the wide side plate. The air outlet 10b on the wide side plate is closer to the screws 82 on the damper 50 and can be used as a maintenance port.

[0168] Specifically, the first air outlet 10c on the first side plate 11 can be used as a maintenance port for the first air valve 501, and the second air outlet 10d on the second side plate 12 can be used as a maintenance port for the second air valve 502.

[0169] In some embodiments, on the same air valve 50, the open end of the hook 81 faces the side closer to the screw 82. After the screw 82 between the air valve 50 and the air valve bracket 60 is unscrewed, the air valve 50 can be pulled towards the screw 82 to separate the air valve 50 from the air valve bracket 60.

[0170] The hook 81 is provided on the damper bracket 60 and can be formed by bending a portion of the damper bracket 60. The hook 81 extends from the end connected to the damper bracket 60 to its free end in a direction close to the screw 82, so that the open end of the hook 81 faces the side close to the screw 82.

[0171] In some embodiments, the hook 81 includes a hook root and a hook portion. The hook root extends outward from one end connected to the damper bracket 60 to the other end, and the hook portion is connected to the end of the hook root away from the damper bracket 60. The hook portion extends away from the end connected to the hook root in a direction away from the partition plate 16.

[0172] The outer frame 51 of the damper has a slot 51b on its edge, and a hook 81 is connected to the outer frame 51 of the damper from the slot 51b. The hook 81 is a cantilever structure connected to the damper bracket 60. It has a certain amount of deformation. The hook part abuts against the surface of the outer frame 51 of the damper to press the outer frame 51 of the damper onto the damper bracket 60.

[0173] The slot 51b is longer than the hook 81 in the horizontal direction and longer than the hook 81 in the vertical direction, so that the hook 81 can pass through the slot 51b. During assembly, align the slot 51b of the air valve 50 with the hook 81, and then move the air valve 50 laterally towards the root of the hook so that the hook part hooks onto the outer frame 51 of the air valve.

[0174] In some embodiments, the hooks 81 have two hooks arranged vertically, the upper hook 81 is used to press the upper edge of the air valve outer frame 51, and the lower hook 81 is used to press the lower edge of the air valve outer frame 51.

[0175] The screw 82 has two parts, one at the top and one at the bottom, which connect the upper and lower ends of the air valve 50 to the air valve bracket 60 respectively.

[0176] When the damper 50 is closed, there may be a small gap between adjacent blades 52. For example, due to manufacturing errors or deformation of the blades 52, the two blades 52 may not achieve the ideal tight fit. The airflow impacting the closed damper 50 will generate abnormal noise due to the small gap, affecting the user experience.

[0177] In this application, reference is made to Figures 11 to 13 When the air valve 50 is in the closed state, the gap width Δ between two adjacent swing blades 52 is ≥2mm, and the abnormal noise is eliminated by increasing the gap.

[0178] In some embodiments, the gap width Δ≤4mm is used to avoid excessive air leakage when the air valve 50 is closed due to the gap being too large.

[0179] Therefore, when the air valve 50 is in the closed state, the gap width Δ between the adjacent blades 52 is within this range, which can eliminate the abnormal noise caused by the small gaps and reduce the air leakage at the air valve 50, and has almost no impact on the air volume of the air conditioner.

[0180] For example, Δ can be 2mm, 3mm, or 4mm. In the current example, Δ = 3mm.

[0181] In some embodiments, the circles containing the outer contours of two adjacent blades 52 intersect when projected onto a plane perpendicular to the rotation center line of the blade 52. On the blade 52, a portion of the edge of the swing surface protrudes outward along the thickness direction of the blade 52 to form a boss 523. When the damper 50 is in the closed state, the boss 523 abuts against its adjacent blade 52, creating a gap between two adjacent blades 52.

[0182] The two surfaces of the oscillating blade 52 are the first plate surface 521 and the second plate surface 522, respectively. When the air valve 50 is in the closed state, the gap between the bottom of the first plate surface 521 of the upper oscillating blade 52 and the top of the second plate surface 522 of the lower oscillating blade 52 is a slit, and the slit width Δ is the vertical distance between the two plates. The protrusion 523 protrudes from the plate surface by a dimension equal to the slit width Δ between two adjacent oscillating blades 52.

[0183] In this application, a boss 523 is provided on the swing blade 52 to increase the gap between the swing blades 52, so as to meet the requirement of Δ≥2mm.

[0184] In some embodiments, the two ends of the oscillating blade 52 in the width direction are respectively provided with a first boss 524 and a second boss 525, which are located on different surfaces of the oscillating blade 52. When the air valve 50 is in the closed state, in two adjacent oscillating blades 52, the first boss 524 on one oscillating blade 52 abuts against the second boss 525 on the other oscillating blade 52. The arrangement of the first boss 524 and the second boss 525 creates a gap between the oscillating blades 52.

[0185] The sum of the dimensions of the first boss 524 protruding from the plate surface and the dimensions of the second boss 525 protruding from the plate surface is the gap width Δ between the two adjacent blades 52.

[0186] In some embodiments, when the air valve 50 is in the closed state, the surface of the boss 523 away from the sway vane 52 is parallel to the plate surface of the sway vane 52, such that when the boss 523 abuts against the plate surface of its adjacent sway vane 52, the plate surfaces of the two sway vanes 52 are parallel.

[0187] In some embodiments, the oscillating blade 52 is centrally symmetrical with respect to its own rotation center line, so that the two ends of the oscillating blade 52 in the length direction can be used interchangeably. During assembly, it is not necessary to distinguish the installation direction of the oscillating blade 52, which improves the versatility and assembly efficiency of the oscillating blade 52.

[0188] The oscillating blade 52 includes a first oscillating blade portion and a second oscillating blade portion located on both sides of its rotation center line. A first boss 524 is provided on the first oscillating blade portion, and a second boss 525 is provided on the second oscillating blade portion.

[0189] Projecting onto a plane perpendicular to the rotation center line of the pendulum 52, the projection points of the first pendulum portion and the second pendulum portion relative to the rotation center line of the pendulum 52 are centrally symmetrically distributed, and the projection points of the second boss 525 and the first boss 524 relative to the rotation center line are centrally symmetrically distributed.

[0190] In some embodiments, the bosses 523 are provided at intervals along the length direction of the blades 52, so that the bosses 523 support the blades 52 in the length direction, thereby making the gap width Δ between the two blades 52 in the length direction relatively uniform.

[0191] In the current example, bosses 523 are provided at both ends and the middle of the blade 52 along its length. If bosses 523 are only provided at both ends of the blade 52, the middle of the blade 52 along its length may deform due to the lack of support, which may cause the gap width Δ between the two blades 52 to be too small or too large.

[0192] In some embodiments, continue to refer to Figure 11 The two rotating shafts of the oscillating blade 52 are the first rotating shaft 526 and the second rotating shaft 527. The two opposing side frames of the outer frame 51 of the damper are the first side frame 511 and the second side frame 512. The first side frame 511 is provided with a first mounting hole, and the second side frame 512 is provided with a second mounting hole; the first rotating shaft 526 is inserted into the first mounting hole, and the second rotating shaft 527 is inserted into the second mounting hole.

[0193] The second frame 512 has a notch 5121, which extends from the outer surface of the second frame 512 to communicate with the second mounting hole. The second rotating shaft 527 is installed into the second mounting hole through the notch 5121.

[0194] The air valve 50 includes a mounting bracket 53, which is connected to the side of the second frame 512 away from the first frame 511. The end of the second rotating shaft 527 passes through the second mounting hole and is inserted into the mounting bracket 53.

[0195] During assembly, first insert the first rotating shaft 526 of the swing blade 52 into the first mounting hole, then install the second rotating shaft 527 of the swing blade 52 into the second mounting hole from the notch 5121, and finally fix the fixing bracket 53 to the second frame 512. This is how the swing blade 52 can be installed.

[0196] In some embodiments, the fixing frame 53 is provided with an outwardly protruding positioning part 531, which is inserted into the notch 5121 to achieve positioning of the fixing frame 53 and the second frame 512. The fixing frame 53 and the second frame 512 are fastened together by screws.

[0197] In some embodiments, the air valve 50 includes an air valve motor 54, the output shaft of which is connected to a rotating shaft of the oscillating blade 52 to serve as a driving device for rotating the oscillating blade 52.

[0198] The air valve motor 54 can be fixedly installed on the first frame 511, and its output shaft is connected to the first rotating shaft 526 of the swing blade 52.

[0199] In some embodiments, a receiving groove 51a is provided on the first frame 511. The receiving groove 51a is open on the side away from the damper bracket 60. The damper motor 54 is mounted in the receiving groove 51a from the open side of the receiving groove 51a.

[0200] A mounting post is provided on the cavity side wall of the receiving groove 51a near the swing blade 52. The lug on the air valve motor 54 abuts against the mounting post and is connected to the mounting post by screws.

[0201] The output shaft of the damper motor 54 is inserted into the first rotating shaft 526. The output shaft of the damper motor 54 has an anti-rotation plane, and the first rotating shaft 526 has a key that matches the anti-rotation plane. The cooperation between the anti-rotation plane and the key prevents the oscillating blade 52 from rotating relative to the output shaft of the damper motor 54.

[0202] In some embodiments, the damper 50 includes a cover plate 55, which is connected to the damper frame 51 corresponding to the receiving groove 51a to cover the receiving groove 51a, thereby protecting the damper motor 54 from condensation.

[0203] The cover plate 55 includes a first plate and a second plate connected in an "L" shape. The first plate abuts against the cavity wall of the receiving groove 51a away from the sway vane 52, and the first plate is connected to the cavity wall by screws. The second plate covers the side of the receiving groove 51a away from the air valve bracket 60.

[0204] In some embodiments, the air valve motor 54 is located on the side of the air valve outer frame 51 near the wide side plate, so that the air valve motor 54 can be disassembled and repaired separately from the maintenance port.

[0205] In some embodiments, refer to Figures 11 to 13Multiple blades 52 are connected by a connecting rod 56. The air valve motor 54 is connected to one blade 52, and when this blade 52 rotates, it drives the other blades 52 to rotate together through the connecting rod 56.

[0206] In the prior art, the connecting rod 56 is usually connected to the blade 52 via an open retaining ring. However, the open retaining ring is under high stress for a long time, which can easily lead to creep relaxation, causing the connecting rod 56 to detach from the blade 52.

[0207] In this application, the swing blade 52 is provided with a linkage shaft portion 528 whose axial direction is parallel to the rotation center line of the swing blade 52. The linkage shaft portion 528 is inserted into the connecting rod 56. The outer periphery of the linkage shaft portion 528 is provided with an anti-disengagement protrusion 5281. When the anti-disengagement protrusion 5281 abuts against the side of the connecting rod, it is used to prevent the connecting rod 56 from disengaging from the linkage shaft portion 528.

[0208] The linkage shaft 528 and the swing blade 52 are connected by a linkage connection 529. The linkage connection 529 and the anti-detachment protrusion 5281 are located on both sides of the connecting rod 56 to stop the connecting rod 56 from detaching from the linkage shaft 528 axially.

[0209] In some embodiments, the connecting rod 56 is provided with a through linkage insertion hole 561 to mate with the linkage shaft portion 528. The linkage insertion hole 561 is provided with a keyway 562 through which the anti-disengagement protrusion 5281 passes. During assembly, the linkage insertion hole 561 of the connecting rod 56 is aligned with the linkage shaft portion 528 of the oscillating blade 52, the keyway 562 is aligned with the anti-disengagement protrusion 5281, and then the connecting rod 56 is moved axially so that the connecting rod 56 is fitted onto the linkage shaft portion 528.

[0210] When the swing blade 52 rotates between the closed and open states, the anti-detachment protrusion 5281 is always misaligned with the keyway 562, thereby ensuring the anti-detachment protrusion 523's stopping and anti-detachment function on the connecting rod 56.

[0211] In some embodiments, an axial edge of the linkage socket 561 is provided with an outwardly flared portion, and / or, the linkage shaft portion 528 and the anti-detachment protrusion 5281 are provided with guide slopes to guide the linkage shaft portion 528 into the linkage socket 561, thereby improving assembly efficiency.

[0212] In some embodiments, the two ends of the swing blade 52 in the width direction are the first end and the second end of the swing blade 52, respectively; the linkage shaft portion 528 is provided near the first end of the swing blade 52, and the anti-detachment protrusion 5281 is provided on the side of the linkage shaft portion 528 away from the second end.

[0213] The anti-detachment protrusion 5281 is located on the edge side of the swing blade 52 in the width direction, which is conducive to the installation of the anti-detachment protrusion 5281 onto the connecting rod 56 and improves the assembly convenience.

[0214] In some embodiments, the link 56 includes a link body portion 563. The link body portion 563 is rod-shaped and extends along the height direction Z in the length direction.

[0215] The connecting rod 56 includes a plurality of linkage plug-in parts 564 that are connected one-to-one with the swing blade 52. The plurality of linkage plug-in parts 564 are spaced apart along the length direction of the connecting rod 56 and connected to the connecting rod body part 563. The linkage plug-in hole 561 is provided on the linkage plug-in part 564.

[0216] The oscillating blade 52 rotates 90° from the closed state to the open state. Projected onto a plane perpendicular to the axis of the linkage connector 564, when the air valve 50 is in the closed state, the anti-detachment protrusion 5281 passes through the line P connecting the centers of multiple linkage connectors 564; at any linkage connector 564, the line passing through the center of the linkage connector 564 and perpendicular to the line P is line Q, and the keyway 562 and the anti-detachment protrusion 5281 are located on both sides of line Q, and are located on the side of the line P closer to the connecting rod body 563.

[0217] The keyway 562 and the anti-detachment protrusion 5281 are located on both sides of the line Q, which allows the anti-detachment protrusion 5281 to always be offset from the keyway 562 during the rotation of the blade 52.

[0218] The keyway 562 is located on the side of the connecting line P closer to the connecting rod body 563, which can reduce the area of ​​the linkage insertion part 564. If the keyway 562 is located on the side of the connecting line P away from the connecting rod body 563, then in order to accommodate the keyway 562 and ensure the structural strength of the linkage insertion part 564, the wall thickness of the part of the linkage insertion part 564 away from the connecting rod body 563 is increased, which will increase the area of ​​the linkage insertion part 564.

[0219] In some embodiments, the linkage shaft 528 is located at the end of the swing blade 52 closest to the air valve motor 54, which ensures the synchronicity of the rotation of multiple swing blades 52. When the air valve motor 54 drives the swing blade 52 connected to it to rotate, since the connecting rod 56 is close to the air valve motor 54, the driven swing blade 52 can promptly drive the connecting rod 56 to move, reducing the motion delay of the connecting rod 56 relative to the driven swing blade 52.

[0220] In some embodiments, refer to Figure 14 The air outlet 10b structure can be an optional accessory. The indoor unit of the air conditioner may include the indoor unit main unit 200 and the air outlet component 300.

[0221] The indoor unit main unit 200 can be used as a finished product. The indoor unit main unit 200 includes a main unit housing 210. The main unit housing 210 forms the appearance of the indoor unit main unit 200.

[0222] The main unit housing 210 is provided with an air inlet 10a and a main unit air outlet 210b. When the indoor unit 200 is used alone, the main unit air outlet 210b supplies air to the room.

[0223] The air inlet 10a and the main unit air outlet 210b are connected to form the main air duct 101. The fan 20 and the heat exchanger 30 are located inside the main unit housing 210.

[0224] The air outlet component 300 includes an air outlet housing 310. The air outlet housing 310 is connected to the main unit housing 210 corresponding to the main unit's air outlet 210b, and the air outlet housing 310 and the main unit housing 210 are connected to form a housing 10. The air outlet housing 310 is provided with multiple air outlets 10b, and an air outlet chamber 102 is provided inside the air outlet housing 310. An air valve 50 is connected to the end of the air outlet housing 310 near the main unit's air outlet 210b.

[0225] The two ends of the air valve bracket 60 along its length are connected to the side wall of the main air housing 10, the upper end of the air valve bracket 60 is connected to the top wall of the air outlet housing 310, and the lower end of the air valve bracket 60 is connected to the bottom wall of the air outlet housing 310.
