Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit and an air conditioner. Background Technology

[0002] This section provides only background information relevant to this application and is not necessarily prior art.

[0003] Air conditioners regulate indoor temperature, humidity, and other environmental factors. The indoor unit of an air conditioner typically has an air inlet and an air outlet. Airflow enters the air conditioner through the inlet and exits through the outlet, improving the efficiency of indoor environmental regulation. The airflow directionality of the indoor unit significantly impacts the efficiency of indoor environmental regulation and user comfort. Utility Model Content

[0004] The purpose of this application is to at least improve the airflow directionality of the indoor unit of an air conditioner and enhance the user experience. This purpose is achieved through the following technical solution: The first aspect of this application proposes an indoor air conditioning unit including a housing, a first air guide plate, and a first drive mechanism. The housing has an air outlet. The first air guide plate is slidably engaged with the housing in the vertical direction of the housing. The first drive mechanism is installed on the housing and connected to the first air guide plate, and is used to drive the first air guide plate to slide in the vertical direction to move closer to or away from the air outlet.

[0005] According to the air conditioner indoor unit of this application, the first air guide plate is configured to slide and rise along the vertical direction of the casing by the first driving mechanism. Compared with the rotation method, the vertical sliding and rising form of the first air guide plate allows for a smaller distance between the first air guide plate and the air outlet, which can improve the airflow guiding effect of the first air guide plate. At the same time, the gap between the first air guide plate and the casing and other structures can be reduced, resulting in a tighter structural fit, reducing air leakage gaps, improving the airflow guidance of the air conditioner indoor unit, and improving the air conditioner indoor unit's regulation efficiency of the indoor environment and the user's comfort. Furthermore, the vertical sliding and rising form of the first air guide plate can reduce the possibility of the first air guide plate intruding into the casing. When the air conditioner indoor unit is equipped with a louver structure for air guidance, the installation space of the louver structure inside the air conditioner indoor unit can be increased, the air guiding area of ​​the louver structure can be increased, thereby improving the airflow guidance of the louver structure, improving the air conditioner indoor unit's regulation efficiency of the indoor environment, and the user's comfort.

[0025] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0026] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The term “a plurality” means two or more (including two). The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a specific order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0027] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0028] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0029] like Figures 1 to 15 As shown, according to an embodiment of this application, an indoor air conditioning unit is proposed, including a housing 1, a receiving cavity for accommodating functional components and an air duct 16 are provided inside the housing 1, the housing 1 has an air outlet 11, the air outlet 11 is connected to the air duct 16, the air outlet 11 can be provided at the front of the housing 1 and is used to exhaust air into the room.

[0030] The housing 1 can house the internal functional components of the air conditioner. An air inlet 18 can also be provided on the housing 1, and the air inlet 18 and the air outlet 11 can be located on different walls of the housing 1. For example, as... Figure 2 and Figure 3 As shown, the indoor unit of the air conditioner is a wall-mounted indoor unit, and an air inlet 18 can be provided on the top side of the casing 1. The air inlet 18 can be configured as a grille structure. Exemplarily, in some embodiments, an air inlet 18 can also be provided on the front side 111 of the casing 1. The functional components inside the housing 1 may include an indoor heat exchanger 7, an indoor fan, etc. The indoor heat exchanger 7 is connected to the cooling / heating system of the air conditioner. The indoor heat exchanger 7 is used to exchange heat with the air flowing through it. The indoor fan is used to guide the airflow from the air inlet 18 through the indoor heat exchange and then to the air outlet 11.

[0031] Optional, such as Figure 2 and Figure 3 As shown, in some embodiments, the functional components within the housing 1 include a sway structure 6. The sway structure 6 is disposed in the air duct 16 and located upstream of the air outlet 11. The sway structure 6 can be configured to oscillate in the left-right direction X so that the airflow flows out through the air outlet 11 towards the left front or right front under the action of the sway structure 6.

[0032] The indoor unit of the air conditioner also includes a first air guide plate 2, which is slidably engaged with the housing 1 along the vertical direction Z of the housing 1. The first air guide plate 2 is positioned corresponding to the air outlet 11. Within the sliding range of the first air guide plate 2 along the vertical direction Z, the first air guide plate 2 can move closer to or further away from the air outlet 11, so that the first air guide plate 2 can switch between a position that blocks the air outlet 11 (refer to the first position) and a position that avoids the air outlet 11 (refer to the second position).

[0033] It is understandable that the first air guide plate 2 and the housing 1 slide in the vertical direction Z. This can be understood as the first air guide plate 2 being able to move linearly relative to the housing 1 in the vertical direction Z to change the position of the first air guide plate 2 in the vertical direction Z.

[0034] The first air guide plate 2 refers to a plate-shaped structure with airflow guiding function. The first air guide plate 2 can adjust the air delivery angle of the air outlet 11 by sliding up and down, and when the indoor unit of the air conditioner is turned off, the first air guide plate 2 can act as a shielding and sealing component for the air outlet 11. The first air guide plate 2 can extend from one end of the air outlet 11 to the other end along the length direction of the air outlet 11 (refer to the left-right direction X of the casing 1). The first air guide plate 2 can be a flat plate or an arc-shaped plate, etc.

[0035] Optionally, the first air guide plate 2 can be a closed solid plate (a closed solid plate refers to a plate whose plate surface is basically sealed, that is, a plate whose plate body does not have through holes on both sides of the plate). The plate surface of the first air guide plate 2 has the function of guiding air, and the airflow can flow along the plate surface of the first air guide plate 2 to adjust the air delivery angle of the air outlet 11.

[0036] For example, such as Figure 1 , Figure 3 As shown, in some embodiments, the first air guide plate 2 may also be provided with multiple air outlets 201, wherein the shape of the air outlets 201 may be circular, elliptical, polygonal, etc., and is not limited here. In operation, when the first air guide plate 2 is in the first position, the airflow can be blown into the room through the air outlets 201 on the first air guide plate 2, making the wind feel softer.

[0037] like Figures 9 to 13 As shown, the indoor unit of the air conditioner may also include a first drive mechanism 3. The first drive mechanism 3 is installed on the housing 1 and connected to the first air guide plate 2, and is used to drive the first air guide plate 2 to slide in the vertical direction Z to move closer to or away from the air outlet 11.

[0038] The first air guide plate 2 can be connected to the housing 1 via the first drive mechanism 3. To improve the sliding stability of the first air guide plate 2 along the vertical Z direction, in some embodiments, a guide structure (not shown in the figure) can also be provided between the housing 1 and the first air guide plate 2. The guide structure can be a structure of sliding groove / rail and slider cooperation, etc. The guide structure can provide a certain connection and support for the first air guide plate 2 during its sliding (moving) along the vertical Z direction, and also play a directional and guiding role. The first drive mechanism 3 can be located inside the housing 1 to be hidden within the housing 1, improving the reliability and aesthetic appearance of the indoor air conditioning unit.

[0039] In some technologies, the air guide plate and the housing 1 are configured to rotate together. In this case, in order to achieve the rotation of the air guide plate, the air guide plate needs a large gap with other structures, resulting in many air leakage points. As a result, the machine has poor air guidance and causes a decline in user experience.

[0040] In this embodiment of the air conditioner indoor unit, the first air guide plate 2 is configured to slide and rise along the vertical direction Z of the casing 1 via the first driving mechanism 3. Compared to rotation, the sliding and rising form of the first air guide plate 2 in the vertical direction Z allows for a smaller distance between the first air guide plate 2 and the air outlet 11, thus improving the airflow guiding effect of the first air guide plate 2. Simultaneously, the gap between the first air guide plate 2 and structures such as the casing 1 can be reduced, resulting in a tighter structural fit, reduced air leakage gaps, improved airflow guidance of the air conditioner indoor unit, and enhanced efficiency in regulating the indoor environment, user comfort, and overall user experience.

[0041] Optionally, the indoor unit of the air conditioner is provided with a swaying blade structure 6, which is used to realize the left and right air blowing of the indoor unit of the air conditioner.

[0042] The study found that the air guide plate will intrude into the interior of the housing 1 during rotation. The housing 1 needs to reserve more space in the area near the air outlet 11 to avoid interference between the air guide plate and the oscillating structure 6 during the rotation process. As a result, the space for the oscillating structure 6 is inevitably limited, resulting in a weaker left and right air guiding function of the oscillating structure 6.

[0043] In this embodiment, the air conditioner indoor unit uses a first air guide plate 2 that slides and lifts in the vertical direction Z. This reduces the possibility of the first air guide plate 2 intruding into the casing 1. With the air conditioner indoor unit equipped with a swaying blade structure 6 for air guidance, the space for the swaying blade structure 6 inside the air conditioner indoor unit can be increased, as can the air guiding area of ​​the swaying blades 61 of the swaying blade structure 6. This improves the airflow guidance of the swaying blade structure 6, enhances the air conditioner indoor unit's efficiency in regulating the indoor environment, improves user comfort, and enhances the user experience.

[0044] like Figures 1 to 8 As shown, optionally, in some embodiments, the air outlet 11 includes a first outlet portion 12, which is disposed on the front side of the housing 1, and the first air guide plate 2 includes a main body 21, which is disposed on the front side of the housing 1; the two extreme positions of the lifting stroke of the first air guide plate 2 are a first position and a second position. In the first position, the main body 21 covers the first outlet portion 12, and in the second position, the main body 21 avoids the first outlet portion 12.

[0045] For example, the second position can be set above the first position, and the first air guide plate 2 can be moved upward from the first position to the second position to avoid the air outlet 11, so that the front side of the air outlet 11 is unobstructed and the airflow can flow out from the air outlet 11; the first air guide plate 2 can also be moved downward from the second position to the first position to cover the first outlet 12.

[0046] It should be noted that the first air guide plate 2 can switch between the first position and the second position, and along the vertical direction Z, the first air guide plate 2 can stay at any position between the first position and the second position. The user can manually adjust the position of the first air guide plate 2 as needed.

[0047] It should be noted that in the second position, the motherboard body 21 avoids the first outlet portion 12. This can be understood as the motherboard body 21 at least partially avoiding the first outlet portion 12. In other words, in the second position, a portion of the motherboard body 21 may partially obscure the first outlet portion 12. For example, if the second position is located above the first position, in the second position, a small portion of the motherboard body 21 may protrude beyond the upper air outlet boundary 14 of the air outlet 11, and the lower edge of the motherboard body 21 and the lower air outlet gap of the air outlet 11 form an air outlet gap. Optionally, along the vertical direction Z, in the second position, the motherboard body 21 may at least avoid half or more of the vertical dimension of the first outlet portion 12.

[0048] Optionally, such as Figure 5 As shown, in the first position, the motherboard body 21 can block the air outlet 11, and the motherboard body 21 is located on the outside of the front panel 110.

[0049] For ease of description, the surface of the front panel 110 of the housing 1 surrounding one side of the air outlet 11 along the vertical direction Z is defined as the first end surface 113, that is, the surface of the front panel 110 located above or below the air outlet 11 is the first end surface 113. For example, as shown... Figures 1 to 8 As shown, the air outlet 11 is located at the bottom front end of the housing 1, and the bottom surface of the front panel 110 forms the first end surface 113.

[0050] Optionally, such as Figure 1 , Figure 10 , Figure 11 and Figure 13As shown, in the first position, the projection of the motherboard body 21 along the vertical direction Z toward the first end face 113 is located within the first end face 113.

[0051] In other words, along the front-rear direction Y, the motherboard body 21 does not protrude into the housing 1 relative to the first end face 113, nor does it protrude outward from the housing 1.

[0052] Specifically, in the first position, the outer side of the motherboard body 21 (the side facing away from the inside of the casing 1 and towards the user) may not extend beyond the front side 111 of the casing 1 (the side facing away from the inside of the casing 1 and towards the user), while the inner side of the motherboard body 21 (the side facing the inside of the casing 1 and away from the user) may not extend beyond the rear side of the front panel 110 (the side of the front panel 110 opposite to the front side 111, i.e. the side of the front panel 110 facing the inside of the casing 1).

[0053] The placement of the main board 21 in the first position can improve the appearance consistency of the indoor unit and reduce the possibility of the main board 21 encroaching into the interior space of the casing 1. At the same time, when the indoor unit is turned on with the main board 21 in the first position, the gap between the main board 21 and the front panel 110 can be reduced, thus improving the air guiding effect.

[0054] For example, such as Figure 10 , Figure 11 and Figure 13 As shown, in some embodiments, in a first position, the front side 111 of the front panel 110 is flush with the front side 111 of the motherboard body 21.

[0055] For example, such as Figure 1 As shown, in some embodiments, in a first position, the front panel 110 is slightly recessed inward relative to the outer side of the motherboard body 21.

[0056] Optionally, such as Figure 3 As shown, in the second position, the motherboard body 21 is located on the outside of the front panel 110 of the casing 1.

[0057] It is understandable that the way the motherboard body 21 is located in the second position outside the front panel 110 of the casing 1 can be applied to the way the motherboard body 21 is in the first position in any state.

[0058] For example, the motherboard body 21 is located outside the front panel 110 of the housing 1 in the second position, and the projection of the motherboard body 21 onto the front panel 110 in the first position is located outside the front panel 110. The first drive mechanism 3 drives the motherboard body 21 to move up or down to switch between the first position and the second position.

[0059] For example, such as Figure 3 , Figures 10 to 13As shown, the mainboard body 21 is located on the outside of the front panel 110 of the casing 1 in the second position. In the first position, the projection of the mainboard body 21 along the vertical direction Z toward the first end face 113 is located inside the first end face 113. The first drive mechanism 3 is provided with a corresponding horizontal transmission component 323 and a lifting transmission component 321. In this way, the first drive mechanism 3 can enable the first air guide plate 2 to have both vertical and horizontal movement along the vertical direction Z and horizontal movement along the front and back direction Y.

[0060] In the second position, the main body 21 is located on the outside of the front panel 110 of the housing 1. The structure of the housing 1 is simple, which reduces the complexity of improving the processing of the housing 1, improves the production efficiency of the housing 1, and reduces the cost.

[0061] Optionally, such as Figure 1 and Figure 2 As shown, in some other embodiments, the front panel 110 of the housing 1 is provided with a receiving groove 112, the opening of the receiving groove 112 is set towards the air outlet 11, the receiving groove 112 extends in the vertical direction Z, and the main board body 21 is inserted into the receiving groove 112 at the second position.

[0062] The accommodating groove 112 extends along the vertical direction Z, which can be understood as the groove opening of the accommodating groove 112 extending to the bottom along the vertical direction Z. In the left-right direction X of the casing 1, the length of the accommodating groove 112 can at least cover the length of the motherboard body 21 so that the motherboard body 21 can be inserted into the accommodating groove 112.

[0063] It is understandable that the way the motherboard body 21 is located in the receiving slot 112 in the second position can be applied to the way the motherboard body 21 is in any state in the first position.

[0064] In the second position, the motherboard body 21 is hidden in the receiving groove 112 of the front panel 110 of the case 1, which improves the appearance consistency and aesthetics of the case 1 and enhances the user experience.

[0065] like Figure 3 , Figure 10 , Figure 11 As shown, by way of example, in some embodiments, in a first position, the front side 111 of the front panel 110 is flush with the front side 111 of the motherboard body 21, and in a second position, the motherboard body 21 is located outside the front panel 110 of the housing 1.

[0066] like Figure 1 and Figure 2As shown, by way of example, in some other embodiments, the front panel 110 of the housing 1 is provided with a receiving groove 112. The opening of the receiving groove 112 is provided facing the air outlet 11. The receiving groove 112 extends in the vertical direction Z. In a first position, the main board body 21 is positioned opposite to the receiving groove 112 in the vertical direction Z. In a second position, the main board body 21 is inserted into the receiving groove 112.

[0067] The first drive mechanism 3 may include a first power component 31 and a transmission component. The first power component 31 is connected to the first air guide plate 2 via the transmission component. The first power component 31 provides power to drive the first air guide plate 2 to move up and down in the vertical direction Z via the transmission component. For example, the first power component 31 may include a motor, and the transmission component may include a ball screw. The motor is connected to the first air guide plate 2 via the ball screw and drives the first air guide plate 2 to move up and down.

[0068] Optionally, in some embodiments, the first power component 31 includes a motor, and the transmission component includes a lifting transmission assembly 321, specifically a rack 322. The rack 322 extends generally in the vertical direction Z. The output end of the first power component 31 (i.e., the motor) is provided with a first tooth component 311, which meshes with the rack 322. The rack 322 is arranged in the vertical direction Z and connected to the first air guide plate 2. The first tooth component 311 can be a gear or the like. The output shaft of the motor is connected to the first tooth component 311 and drives the first tooth component 311 to rotate, and drives the rack 322 to move in the vertical direction Z, thereby driving the first air guide plate 2 connected to the rack 322 to rise and fall in the vertical direction Z. The motor can drive the first toothed component 311 to rotate in both directions. The first toothed component 311 can make the rack 322 rise and fall by rotating in different directions. For example, when the motor rotates in the forward direction, the first toothed component 311 rotates in the forward direction and drives the rack 322 to drive the first air guide plate 2 to rise. When the motor rotates in the reverse direction, the first toothed component 311 rotates in the reverse direction and drives the rack 322 to drive the first air guide plate 2 to fall.

[0069] The motor can be installed inside the housing 1, and the first gear component 311 can be installed on the side of the first air guide plate 2 facing the inside of the housing 1, and located inside the housing 1. Optionally, the transmission component can be connected to the first air guide plate 2 through the air outlet 11, and the connection position between the transmission component and the first air guide plate 2 can correspond to the air outlet 11.

[0070] In some embodiments, optionally, multiple first drive mechanisms 3 may be provided, and multiple first drive structures may be arranged at intervals along the left-right direction X of the housing 1.

[0071] For example, such as Figure 9As shown, the first drive mechanism 3 can be configured as two. The two first drive mechanisms 3 are respectively located at both ends of the housing 1 along the left-right direction X, and the two first drive mechanisms 3 are configured with the same structure and are respectively connected to both ends of the first air guide plate 2.

[0072] The reliability of the first air guide plate 2 can be improved by setting multiple first drive mechanisms 3.

[0073] It should be noted that the first drive mechanism 3 with only the lifting transmission assembly 321 can be applied to the first air guide plate 2 moving straight up and down in the first and second positions.

[0074] For example, such as Figure 1 and Figure 2 As shown, the front panel 110 of the housing 1 is provided with a receiving groove 112. The opening of the receiving groove 112 is set towards the air outlet 11. The receiving groove 112 extends along the vertical direction Z. In the first position, the main board body 21 is set directly opposite the receiving groove 112 along the vertical direction Z. In the second position, the main board body 21 is inserted into the receiving groove 112. The first drive mechanism 3 includes a first power component 31 and a rack 322. The rack 322 is fixedly connected to the main board body 21 near the lower edge. The first power component 31 drives the rack 322 to rise and fall through the first gear component 311, so as to drive the main board body 21 (first air guide plate 2) to move straight up or down between the first position and the second position.

[0075] In some embodiments, the transmission component may include a lifting transmission assembly 321 and a horizontal transmission assembly 323. The lifting transmission assembly 321 is connected to the horizontal transmission assembly 323. The first power component 31 is connected to the first air guide plate 2 through the lifting transmission assembly 321 and the horizontal transmission assembly 323. The first drive mechanism 3 is configured such that the first power component 31 drives the lifting transmission assembly 321 and the horizontal transmission assembly 323 to cooperate in action, so that the first air guide plate 2 can move along the front-back direction Y and the up-down direction Z of the housing 1.

[0076] The lifting transmission assembly 321 may include a ball screw or rack 322, etc. The horizontal transmission assembly 323 may be a linkage structure 324, or other structures.

[0077] Optionally, in some implementations, the first power component 31 can be connected to the lifting transmission assembly 321, and then connected to the horizontal transmission assembly 323 via the lifting transmission assembly 321, so that one power component can act on both the lifting transmission assembly 321 and the horizontal transmission assembly 323. Alternatively, in other implementations, the first power component 31 can be connected to the horizontal transmission assembly 323, and then connected to the lifting transmission assembly 321 via the horizontal transmission assembly 323, so that one power component can act on both the lifting transmission assembly 321 and the horizontal transmission assembly 323.

[0078] For example, such as Figures 10 to 13 As shown, in one embodiment, the horizontal transmission assembly 323 includes a linkage structure 324, the lifting transmission assembly 321 includes a rack 322, the output end of the first power component 31 is provided with a first tooth component 311, the first tooth component 311 is meshed with the rack 322 for transmission, the rack 322 is arranged in the vertical direction Z, the rack 322 is connected to the first air guide plate 2 through the linkage structure 324, and the linkage structure 324 can drive the first air guide plate 2 to move in the front-back direction Y of the housing 1 under the lifting action of the rack 322. The connecting rod structure 324 may include a connecting rod, one end of which is hinged to the rack 322 (e.g., rotatably connected via a shaft), and the other end of which is hinged to the first air guide plate 2 (e.g., rotatably connected via a shaft). The rack 322 is constrained by the first power component 31 and the first gear component 311. The position of the rack 322 in the front-rear direction Y is fixed. Therefore, by rotating the connecting rod around the hinge points at both ends, the relative position of the rack 322 to the main body 21 in the front-rear direction Y can be changed.

[0079] Optionally, such as Figure 12 (refer to Figure 12 As shown in the figure, the linkage structure 324 can switch between the horizontal solid line state and the tilted state shown by the dashed line. A first limiting structure 325 is provided at the end of the linkage connected to the rack 322 and at the end of the linkage connected to the first air guide plate 2. The first limiting structure 325 is used to limit the rotation range of the linkage. Specifically, the first limiting structure 325 prevents the linkage from rotating further upward after it reaches a horizontal position, thereby positioning the linkage at its extreme forward position relative to the first air guide plate 2 in the forward-backward direction Y, and stabilizing the first air guide plate 2 at this extreme position. Optionally, as shown in the figure... Figure 10 , Figure 11 and Figure 13 As shown, a second limiting structure 326 is provided on the housing 1. The second limiting structure 326 can act on the connecting rod so that the connecting rod can rotate from the horizontally extended state, thereby retracting the first air guide plate 2 backward along the front-back direction Y.

[0080] The first drive mechanism 3, equipped with a horizontal transmission component 323, allows the motherboard body 21 to be positioned flush with its front side 111 in a first position, and in a second position, with the motherboard body 21 located outside the front panel 110 of the casing 1. Figure 13 As shown, the rising process of the first air guide plate 2 is roughly as follows: Figure 13 As shown in d, in the first position, the connecting rod abuts against the second limiting structure 326, the connecting rod is tilted, the main board body 21 covers the first outlet 12, and the main board body 21 is roughly flush with the front side 111 of the front panel 110 of the housing 1; as Figure 13As shown in diagram a, when the first air guide plate 2 moves upward from the first position, the first power component 31 (motor) of the first drive mechanism 3 is activated, causing the rack 322 to move upward. Under the upward movement of the rack 322, the end of the connecting rod connected to the rack 322 moves upward, and the two ends of the connecting rod rotate, causing the main plate 21 to move towards the front. Until the connecting rod is approximately horizontal, under the action of the first limiting structure 325, the connecting rod remains horizontal, and the main plate 21 moves to the front side of the front panel 110 of the housing 1; as... Figure 13 As shown in b, the first power unit 31 (motor) continues to operate, the rack 322 continues to move upward, the connecting rod always remains horizontal, and drives the first air guide plate 2 to move upward, and can move to the second position. Figure 13 As shown, the process of the first air guide plate 2 descending from the second position is roughly as follows: Figure 13 As shown in b, in the second position, the connecting rod is set approximately horizontally, and the main board 21 is located on the front side of the front panel 110 of the housing 1; as Figure 13 As shown in figures c and d, the first power component 31 (motor) of the first drive mechanism 3 is activated, causing the rack 322 to move downwards. As the rack 322 descends, it drives the horizontally positioned connecting rod and the first air guide plate 2 connected to the connecting rod to descend until the main body 21 moves to the lower side of the front panel 110 (at the same height as the first position). The connecting rod then abuts against the second limiting structure 326. Under the limitation of the second limiting structure 326, the rack 322 continues to drive the end of the connecting rod connected to the rack 322 to move downwards. The connecting rod rotates, causing the main body 21 to retract into the housing 1, ultimately covering the air outlet 11 and positioning it in the first position. The arrows in the figure indicate the cyclical movement of the first air guide plate 2.

[0081] According to some embodiments of this application, such as Figures 1 to 3 , Figure 9 As shown, optionally, the first air guide plate 2 is provided with a plurality of air outlet holes 201 at intervals. The plurality of air outlet holes 201 can be circular holes, elliptical holes, etc.

[0082] For example, the multiple air outlets 201 on the first air guide plate 2 can be evenly spaced.

[0083] For example, the motherboard body 21 is provided with a plurality of air outlets 201, which are arranged from the left end to the right end of the motherboard body 21 and from the upper end of the motherboard body 21 downward, so as to cover the entire surface of the motherboard body 21 at approximately uniform intervals.

[0084] By setting the air outlet 201, the first air guide plate 2 can cover the first outlet 12 during the operation of the indoor unit of the air conditioner, and the airflow can flow into the room from the air outlet 201 of the first air guide plate 2, resulting in a gentler airflow.

[0085] Optionally, such as Figures 1 to 3 and Figure 9 As shown, along the left-right direction X of the housing 1, the air outlet 11 passes through the left side panel 120 and the right side panel of the housing 1. The first air guide plate 2 includes a main body 21 and side panels 22. The two ends of the main body 21 along the left-right direction X are respectively connected to the side panels 22. In the first position, the main body 21 covers the front of the air outlet 11, and the two side panels 22 at both ends cover the left and right sides of the air outlet 11, respectively. Wherein, as Figure 1 and Figure 2 As shown, when the front panel 110 is provided with a receiving groove 112, the receiving groove 112 extends through both sides of the front panel 110 in the left-right direction X.

[0086] By connecting the left side panel 120 and the right side panel through the air outlet 11, the area of ​​the air outlet 11 can be increased, thereby improving the heat exchange efficiency of the indoor unit. The side panels 22 and 23 respectively block the left and right sides of the air outlet 11, improving the appearance consistency of the casing 1.

[0087] For example, the main board 21 and the two side boards 22 can be connected to form a U-shaped structure. The main board 21 and the two side boards 22 can be a single-piece molded structure.

[0088] In some embodiments, air outlets 201 are provided on the main board body 21 and the two side panels 22 respectively. In this way, when the first air guide plate 2 is in the first position, air can be vented to the front, left and right sides of the casing 1 through the side panels 22 and the main board body 21, which improves the user experience.

[0089] For example, the rear end of the left side panel 22 can overlap with the left side panel 120 of the housing 1, and the rear end of the right side panel 22 can overlap with the right side panel of the housing 1. In this way, under the limiting effect of the two side panels 22 and the left and right side panels of the housing 1, the position of the first air guide plate 2 in the left-right direction X can be restricted, thereby improving the reliability of the first air guide plate 2.

[0090] It should be noted that in some embodiments, the air outlet 11 may not penetrate the left side panel 120 and the right side panel of the housing 1. The first air guide plate 2 may still include the side panel body 22. In this case, the left side panel body 22 may be mounted on the left side panel 120, and the right side panel body 22 may be mounted on the right side panel.

[0091] like Figures 1 to 8 As shown, according to some embodiments of this application, optionally, the air outlet 11 further includes a second outlet section 13, the first outlet section 12 is connected to the second outlet section 13, and the second outlet section 13 is disposed on the bottom side of the housing 1; the air conditioner indoor unit further includes a second air guide plate 4, the second air guide plate 4 is rotatably connected to the housing 1, and the second air guide plate 4 can be flipped at the air outlet 11.

[0092] The second outlet 13 is located on the bottom side of the housing 1 (the bottom side can be understood as the side facing the ground). The first outlet 12 is a portion of the air outlet 11, and the second outlet 13 is another portion of the air outlet 11. The indoor air conditioning unit can be a wall-mounted unit. The first outlet 12 of the housing 1 can be formed at the bottom front side of the housing 1, facing downwards, and the second outlet 13 of the housing 1 can be formed at the front end of the bottom surface 141 of the housing 1, facing forwards.

[0093] The air outlet 11 is configured to include a first outlet section 12 and a second outlet section 13, which can increase the air supply area of ​​the air outlet 11 and improve the adjustment range of the air supply angle. This allows users to adjust the air supply angle of the air outlet 11 as needed, thereby improving the user experience.

[0094] The second air guide plate 4 can be flipped to adjust the air delivery angle. The second air guide plate 4 is a plate-like structure with airflow guiding function. It can be a closed solid plate, and its surface guides the airflow, allowing air to flow along its surface to adjust the air delivery angle of the air outlet 11. The second air guide plate 4 can adjust the air delivery angle of the air outlet 11, and when the indoor unit of the air conditioner is off, it can also act as a shielding and sealing component for the air outlet 11. The second air guide plate 4 can extend along the length of the air outlet 11 from one end to the other. It can be a flat plate or a curved plate.

[0095] For example, in some embodiments, the second air guide plate 4 is arranged in a straight line along the length of the air outlet 11. The two side panels of the second air guide plate 4 (the panel refers to the large surface of the second air guide plate 4) are the second inner panel 43 and the second outer panel 44, respectively. The second inner panel 43 is disposed facing the inside of the housing 1, and the second outer panel 44 is disposed facing the outside of the housing 1. The second inner panel 43 is the panel of the second air guide plate 4 facing the inside of the air outlet 11, and the second outer panel 44 is the exposed surface of the second air guide plate 4. The second outer panel 44 can serve as part of the exterior surface of the air conditioner indoor unit. When the airflow flows from the air outlet 11 to the second air guide plate 4, the airflow can flow along the second inner panel 43, which mainly plays the role of guiding the airflow. The second inner panel 43 can have an arc-shaped structure that bulges slightly outward in the middle along the width direction of the second air guide plate 4, and the main body of the second outer panel 44 can be approximately flat.

[0096] The second air guide plate 4 can be rotatably connected to the housing 1 via a rotating shaft, etc. The rotation axis of the second air guide plate 4 can be aligned with the length direction of the housing 1. The second air guide plate 4 can be flipped in the vertical plane to different positions of the air outlet 11, thereby adjusting the air delivery angle.

[0097] For ease of description, the area traversed by the second air guide plate 4 is defined as the rotation stroke of the second air guide plate 4. The rotation stroke of the second air guide plate 4 and the lifting stroke of the first air guide plate 2 can be set to be independent of each other, so that the lifting of the first air guide plate 2 and the flipping of the second air guide plate 4 can be relatively independent.

[0098] By setting the first air guide plate 2 and the second air guide plate 4, the first air guide plate 2 and the second air guide plate 4 can cooperate with each other to adjust the air delivery angle of the air outlet 11. That is, within the lifting stroke of the first air guide plate 2 and the rotation stroke of the second air guide plate 4, the first air guide plate 2 and the second air guide plate 4 can cooperate to adjust the air delivery angle.

[0099] The indoor unit of the air conditioner may also include a second drive mechanism 5, which can be installed on the housing 1. Specifically, it can be installed on the chassis and connected to the second air guide plate 4 to drive the second air guide plate 4 to rotate.

[0100] The second drive mechanism 5 may include a motor and a connecting arm 51. The motor is connected to the second air guide plate 4 via the connecting arm 51. One or two second drive mechanisms 5 may be provided. If two are provided, the two second drive mechanisms 5 may be located at both ends of the second air guide plate 4 along its own length. If only one is provided, the second drive mechanism 5 is located at one end of the second air guide plate 4 along its own length, and the other end of the second air guide plate 4 along its own length is rotatably connected to the housing 1 via the connecting arm 51. The air outlet 11 is located at the bottom front of the housing 1, and the air outlet 11 has an upper air outlet boundary 14 on the upper side and a lower air outlet boundary 15 on the lower side.

[0101] The upper air outlet boundary 14 can be understood by referring to the upper edge of the housing 1 surrounding the air outlet 11. The upper air outlet boundary 14 can be the first end face 113 of the front panel 110 of the housing 1. The lower air outlet boundary 15 can be understood by referring to the lower edge of the housing 1 surrounding the air outlet 11. The lower air outlet boundary 15 can be the end face of the bottom plate 140 of the housing 1 surrounding the rear side of the air outlet 11. The front bottom of the housing 1 refers to the area at the lower front of the housing 1, which can be understood by referring to the location of the first outlet 12 and the second outlet 13. The vertical direction Z can be understood by referring to the vertical direction, and the front-back direction Y is roughly parallel to the horizontal direction.

[0102] According to some embodiments of this application, optionally, the second air guide plate 4 has two opposite ends along its width direction, defined as the first end 41 and the second end 42, and the two extreme postures of the rotation stroke of the second air guide plate 4 are the first extreme posture and the second extreme posture, respectively. Figure 4 As shown, in the first extreme posture (in the first extreme posture, Figure 4The second air guide plate 4 is shown in solid line. The second end 42 is located below the first end 41 and in front of the first end 41. The second end 42 forms an air outlet gap with the upper air outlet boundary 14. Figure 4 As shown, in the second extreme posture (in the second extreme posture, Figure 4 The second air guide plate 4 is shown in dashed lines. The second end 42 is located above the first end 41 and behind the first end 41. The first end 41 and the lower air outlet boundary 15 form an air outlet gap.

[0103] The air outlet gap can be understood as the airflow outlet area formed by the second air guide plate 4 and the casing 1.

[0104] In the first extreme posture, the first end 41 is the end of the second air guide plate 4 closest to the impeller 8 of the indoor fan, and the second end 42 is the end away from the impeller 8. The second air guide plate 4 guides the airflow forward and upward. At this time, the first air guide plate 2 can be raised to the second position. The first extreme posture can form the maximum airflow angle of the indoor air conditioning unit, which can be used as the default cooling angle. In the first extreme posture, the second air guide plate 4 can be parallel to the lower profile line 17 of the air duct 16 near the air outlet 11, that is, the airflow flows out of the casing 1 roughly along the direction of the air duct 16.

[0105] In the second extreme posture, the second end 42 is the end of the second air guide plate 4 that is close to the impeller 8 of the indoor fan, and the first end 41 is the end that is far away from the impeller 8. The second air guide plate 4 forms a forward and downward guiding effect on the airflow.

[0106] The second air guide plate 4 can flip between a first extreme posture and a second extreme posture. The stroke of the second air guide plate 4 between the first extreme posture and the second extreme posture is the rotation stroke. The extreme posture of the second air guide plate 4 limits the flip stroke of the second air guide plate 4, and the flip stroke of the second air guide plate 4 can improve the adaptability of the indoor unit of the air conditioner to various air supply angle requirements.

[0107] Optionally, in this embodiment, when the indoor unit of the air conditioner is turned off, the first air guide plate 2 is in the first position, covering the first outlet 12, and the second air guide plate 4 covers the second outlet 13.

[0108] For example, the indoor unit of the air conditioner is a wall-mounted indoor unit. In the off state, the width direction of the first air guide plate 2 is approximately parallel to the front side 111 of the casing 1, and the first air guide plate 2 is set approximately along the vertical direction Z. The width direction of the second air guide plate 4 is approximately parallel to the bottom surface 141 of the casing 1, and the second air guide plate 4 is set approximately along the horizontal direction.

[0109] refer to Figure 5As shown, in some embodiments, when the indoor unit of the air conditioner is turned off, the first air guide plate 2 can block the front side of the second air guide plate 4. When the indoor unit of the air conditioner is turned off, the second air guide plate 4 can be blocked by the first air guide plate 2 when viewed from the front of the indoor unit, resulting in better appearance consistency and overall integrity, and improving aesthetics.

[0110] For example, in the off state, the second air guide plate 4 is flush with the bottom surface 141 of the housing 1.

[0111] The second air guide plate 4 is flush with the bottom surface 141 of the casing 1. This can be understood as the bottom-facing surface of the second air guide plate 4 (refer to the second outer panel 44) being approximately flush with the bottom surface 141 of the casing 1. The main body of the second outer panel 44 is approximately coplanar with the bottom surface 141 of the casing 1. In other words, the second air guide plate 4 smoothly connects to the bottom surface 141 of the casing 1 in the off state, thus improving the appearance consistency and overall integrity of the casing 1 in the off state. The shape of the second outer panel 44 can be matched to the shape of the bottom surface 141 of the casing 1 to further improve the appearance consistency of the indoor air conditioning unit.

[0112] It should be noted that two relatively flat items can be considered flat as long as they are roughly flat. Specifically, they can be considered flat if they are within the allowable deviation range of processing error, or if the user perceives them as flat to the naked eye.

[0113] Optionally, the indoor unit of the air conditioner in this embodiment may have a preset cooling mode (i.e., the default cooling mode in the default on state). For example... Figure 7 As shown, in the preset cooling mode, the second air guide plate 4 is in the first extreme posture, and the first air guide plate 2 is in the second position.

[0114] The aforementioned preset cooling mode can provide a larger air outlet angle, improving the cooling effect. Optionally, in the maximum air outlet mode of the air conditioner indoor unit under cooling conditions, the posture and position of the first air guide plate 2 and the second air guide plate 4 are the same as in the preset cooling mode.

[0115] Optionally, the indoor unit of the air conditioner in this embodiment may have a preset anti-direct-blow mode, which can be the mode corresponding to activating the anti-direct-blow function in cooling mode. For example... Figure 6 As shown, in the preset anti-direct-blow mode, the second air guide plate 4 rotates so that the second end 42 is above the first end 41 and in front of the first end 41. The second end 42 and the upper air outlet boundary 14 form an air outlet gap, and the first air guide plate 2 can be in the second position.

[0116] Optionally, the indoor unit of the air conditioner in this embodiment may have a preset windless mode, which can be applied to both cooling and heating modes. For example... Figure 5 As shown, the first air guide plate 2 is provided with a plurality of air outlet holes 201 at intervals. In the preset windless mode, the first air guide plate 2 is in the first position, covering the first outlet 12, and the second air guide plate 4 can cover the second outlet 13.

[0117] It should be noted that in the preset windless mode and the power-off state, the position or posture of the first air guide plate 2 can be the same, and the posture and position of the second air guide plate 4 can be the same.

[0118] Optionally, the indoor unit of the air conditioner in this embodiment may have a preset heating mode. The preset heating mode can be considered as a powerful heating mode or a heating mode automatically defaulted to when the unit is turned on. For example... Figure 8 As shown, in the preset heating mode, the second air guide plate 4 is in the second extreme posture, the first air guide plate 2 can be in the second position, or the first air guide plate 2 can be in a position between the first position and the second position.

[0119] The preset heating mode directs the airflow downwards as much as possible, effectively achieving the effect of blowing the heating airflow downwards. This solves the problem of poor downward airflow in traditional wall-mounted heaters and improves the user experience.

[0120] It should be noted that when the indoor unit of the air conditioner is in heating mode, the first air guide plate 2 can be located in the first position or between the first and second positions, and block the front side of the second air guide plate 4. In this way, even if the second air guide plate 4 is far from the upper air outlet boundary 14, the first air guide plate 2 can have a good wind blocking and air compression effect. Therefore, the adjustable range of the downward air guiding angle of the second air guide plate 4 is large. Specifically, the downward air guiding angle of the second air guide plate 4 can be increased from 30 degrees to 90 degrees.

[0121] It should also be noted that the posture or position limitation of the first air guide plate 2 and the second air guide plate 4 in the above mode is only a preset posture or position in the preset mode. In actual use, the user can manually adjust the posture or position of the first air guide plate 2 and the second air guide plate 4 in each mode, selectively making the first air guide plate 2 at any position or posture of its own lifting stroke, and selectively making the second air guide plate 4 at any posture or position of its own rotation stroke.

[0122] like Figures 2 to 8 and combined Figure 14 and Figure 15As shown, the indoor unit of the air conditioner may also include a sway structure 6. An air duct 16 is provided inside the casing 1. The air duct 16 is connected to the air outlet 11. The sway structure 6 is provided inside the air duct 16. The sway structure 6 includes a plurality of sway blades 61 arranged at intervals along the left-right direction X of the casing 1. The extension directions of the sway blades 61 intersect in the left-right direction X. The sway blades 61 include a connecting shaft portion 612 and a blade portion 611. The blade portion 611 is connected to the side of the connecting shaft portion 612 facing the air outlet 11 and the side facing away from the air outlet 11, respectively.

[0123] The oscillating blade structure 6 can be driven by a third drive mechanism (not shown in the figure). The third drive mechanism can be located at one end of the housing 1 along the left-right direction X. The third drive mechanism can be in the form of a motor and a transmission assembly. The third drive mechanism is connected to the connecting shaft 612 to drive the oscillating blade 61 to swing.

[0124] For example, the oscillating blade structure 6 may include a mounting rod 62, which extends along the left-right direction X of the housing 1. The connecting shaft portion 612 of each oscillating blade 61 is connected to the mounting rod 62. The third drive mechanism is connected to the multiple oscillating blades 61 through the mounting rod 62 to drive the multiple oscillating blades 61 to swing synchronously.

[0125] The two blade sections 611 of the oscillating blade structure 6 can be connected into a single structure by the connecting shaft section 612. Each blade section 611 is arranged in a gradually narrowing arc shape from the end near the connecting shaft section 612 to the end away from the connecting shaft section 612.

[0126] like Figure 16 As shown, in some existing technologies, due to the limited form of the air guide plate flipping, the blades of the oscillating blade structure can only have blades on the side of the connecting shaft facing the inside of the housing. The oscillating blade area is small. In one model, the length of the oscillating blade is about 57 mm and the single-sided area of ​​the oscillating blade is 1158 square millimeters.

[0127] In this embodiment, by setting the first air guide plate 2 to a vertical lifting form, the space occupied by the intrusion during the movement of the first air guide plate 2 is reduced. When the second air guide plate 4 is provided, the angle of the second air guide plate 4 is limited and will not intrude significantly, thus increasing the size of the oscillating blade 61. Blade portions 611 can be provided on both sides of the connecting shaft portion 612 of the oscillating blade 61. Furthermore, when applied to the same type of machine as described above, such as... Figure 15As shown, the dimensions of the oscillating blade 61 can be set to 117 mm, and the single-sided area of ​​the oscillating blade 61 is 3277 square millimeters. The change in the oscillating blade structure 6 increases the area of ​​the oscillating blade 61 by approximately three times, which is of great significance for lateral airflow guidance. The measured airflow angle can be increased from 126° to 138° (the area of ​​the oscillating blade 61 affects the airflow angle it forms; the larger the length and area of ​​the oscillating blade 61, the better the control over the airflow angle, and due to the long guide, the airflow angle formed is larger), significantly improving wide-area airflow.

[0128] The application also provides an air conditioner, including the indoor unit of the air conditioner proposed in this application or any embodiment of this application.

[0129] An air conditioner may also include an outdoor unit, which includes a compressor, an outdoor heat exchanger, an expansion valve, a four-way valve, etc. The compressor, the outdoor heat exchanger, the expansion valve, the four-way valve, and the indoor heat exchanger are connected by refrigerant pipes to form a refrigeration / heating system.

[0130] The air conditioner in this embodiment has the same beneficial effects as the indoor air conditioner proposed in this application or any embodiment of this application.

[0131] It should be noted that the left-right, front-back, and up-down directions of the casing 1 in this article are defined with reference to the usage state when the indoor unit of the air conditioner is assembled indoors. It should also be noted that the length directions of the air outlet 11, the casing 1, the first air guide plate 2, and the second air guide plate 4 can be understood as being in the same direction. In wall-mounted indoor units, the length direction usually corresponds to the left-right direction X of the casing 1. The width directions of the first air guide plate 2 and the second air guide plate 4 can be understood as the extension length of each air guide plate along the width direction of the air outlet 11, which is approximately perpendicular to the aforementioned length directions.

[0132] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions. The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
