Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to a wall-mounted air conditioner indoor unit. Background Technology

[0002] A typical indoor unit of a wall-mounted air conditioner includes a casing and an indoor heat exchanger and a heat exchange fan located inside the casing. The indoor heat exchanger is used to exchange heat with the airflow inside the casing. The heat exchange fan drives indoor air to enter the casing through the air inlet at the top of the casing. After exchanging heat with the indoor heat exchanger, the air flows out through the air outlet at the bottom front of the casing.

[0003] In a wall-mounted air conditioner indoor unit, the air outlet structure is one of the key components. Its core function is to guide and regulate the airflow direction at the air outlet to meet the different users' needs for air delivery angle and range. Common air outlet structures typically consist of a guide vane and rotating blades. The guide vane rotates relative to the unit casing to open or close the air outlet. The axis of rotation of the guide vane extends along the length of the air outlet to guide airflow vertically. Several rotating blades are arranged at intervals along the length of the air outlet, and the axis of rotation of the guide vane extends along the height of the unit casing to guide airflow horizontally.

[0004] In the left-right direction, the existing rotating blades have a limited range of angle and position, resulting in dead zones in the indoor space. This makes it difficult to meet users' needs for multi-angle, wide-range airflow, while also affecting the air conditioner's cooling and heating performance and overall comfort. Furthermore, existing rotating blades often fail to effectively control the distribution and uniformity of airflow when changing the airflow direction, easily causing user discomfort. Moreover, rotating blades cannot achieve a windless airflow effect. To achieve this effect and avoid the cold air from blowing directly on the body, related technologies require a separate windless component, increasing production costs and maintenance difficulty, resulting in lower market competitiveness. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore,

[0006] This utility model provides a wall-mounted air conditioner indoor unit, which includes:

[0007] The housing has an air conditioning inlet at the top and an air conditioning outlet extending along its length at the bottom front side.

[0008] An indoor heat exchanger is located inside the casing and exchanges heat with the air inside the casing;

[0009] A heat exchange fan is disposed inside the housing and located below the indoor heat exchanger;

[0010] An air outlet frame is provided at the air outlet of the air conditioner. The two ends of the air outlet frame along the length direction are rotatably connected to the housing via a rotating shaft, which is used to open or close the air outlet of the air conditioner. The rotating shaft extends along the length direction of the housing.

[0011] Several air guides are spaced apart along the length of the housing in the air outlet frame. Each air guide is rotatably connected to the air outlet frame. Each air guide includes:

[0012] A rotating shaft, the axis of which is perpendicular to the length direction of the housing;

[0013] A drive device, connected to the rotating shaft, is used to drive the air guide to rotate;

[0014] An air guide channel is formed within the air guide component. The air guide channel has an air outlet axis and is configured to guide the airflow inside the housing out of the housing along the extension direction of the air outlet axis.

[0015] When the air guide rotates to a first position where its own air outlet axis is parallel to the length direction of the housing, the air conditioner air outlet of the portion blocked by the air guide is blown out through the gaps between the air guides;

[0016] When the air guide component rotates to a second position where its air outlet axis is perpendicular to the length direction of the housing, the airflow inside the housing is blown forward through the air guide channel;

[0017] When the air guide rotates until its air outlet axis is between the first position and the second position, the airflow inside the housing is blown out at an angle through the air guide channel.

[0018] The above technical solution has the following advantages or beneficial effects: The air outlet frame extends the length of the air outlet channel and increases the rotational adjustment of the air conditioning outlet channel, allowing for length and angle adjustments based on the installation and usage environment. Furthermore, the presence of several air guides within the air outlet frame enables multi-angle adjustment of the air outlet angle, achieving a wider airflow range and more flexible air delivery modes. Specifically, by rotating the air guides, the airflow direction is determined, and the flow path area of ​​the air guide channel is changed, allowing for the selective generation of various airflows to increase the airflow range, soften the airflow feel, and balance airflow speed, resulting in more diverse airflow patterns. When the air guides rotate to the first position, they block and diffuse the airflow, dispersing it in a gentler, more uniform manner, reducing wind speed and volume to achieve a windless effect. This avoids the discomfort that might be caused by strong winds blowing directly on the body, improving user comfort.

[0019] According to embodiments of this disclosure, the air guide includes:

[0020] Two guide plates are arranged opposite each other and spaced apart along a direction perpendicular to the air outlet axis;

[0021] Two fixed plates are configured and positioned opposite each other at the top and bottom of the guide plate, and the two fixed plates and the two guide plates together form the air guide channel;

[0022] The rotating shaft is vertically mounted on the fixed plate, and one of the rotating shafts on the two fixed plates is connected to the driving device.

[0023] The above technical solution has the following advantages or beneficial effects: when the air guide component of the above structure rotates, the angle and position travel range of the guide plate is larger than that of the traditional air guide vane, which further improves the flexibility, accuracy and comfort of air conditioning air delivery.

[0024] According to embodiments of this disclosure, the cross-section of the guide plate perpendicular to the axis of rotation is arc-shaped or straight.

[0025] The above technical solution has the following advantages or beneficial effects: the above setting makes the cross-section of the guide plate arc-shaped or straight plate-shaped, which makes the shape of the air guide channel more in line with the aerodynamic principle, allowing the airflow in the air guide channel to flow more smoothly, reducing airflow resistance and turbulence, thereby improving air supply efficiency, enhancing the uniformity and stability of airflow, and improving user comfort.

[0026] According to an embodiment of this disclosure, the guide plate includes a first guide section and a second guide section arranged along the air outlet axis. The first guide section and the second guide section are connected at an angle, and the angle is set toward the opposite side of the guide plate.

[0027] The above technical solution has the following advantages or beneficial effects: through the first and second guiding sections of the color lake, the airflow can be guided in segments, so that the airflow deflects and diffuses to different degrees at different positions and directions, thereby achieving a more refined and complex airflow distribution.

[0028] According to embodiments of this disclosure, the air guide channel has a tendency to first gradually expand and then gradually shrink in a cross-section perpendicular to the axis of rotation.

[0029] The above technical solution has the following advantages or beneficial effects: the above arrangement makes the air path at the inlet of the diffused air path gradually narrow and the outlet gradually widen. When the airflow passes through the diffused air path, the gradual narrowing at the inlet increases the airflow velocity, while the gradual widening at the outlet decreases the airflow velocity. At the same time, the rapid expansion effect of the diffused air path diffuses the airflow, thereby making the airflow velocity distribution more uniform.

[0030] According to an embodiment of this disclosure, the two guide plates of the air guide are symmetrically arranged along the axial direction of the rotating shaft. The guide plate is an arc plate with its arc center located in the air guide channel. The minimum distance between two guide plates that are close to each other on two adjacent air guides is less than the distance between the guide plate and the axis of the rotating shaft.

[0031] The above technical solution has the following advantages or beneficial effects: the above arrangement makes the minimum distance between adjacent guide plates of the air guide components as close as possible, thereby maximizing the positional deviation of the upstream and downstream guide plates in the flow direction when the air guide components rotate between the first and second positions, significantly enhancing the ability to deflect the airflow direction. At the same time, the airflow guiding section can be lengthened in the flow direction, and the effect of bending the airflow direction is also greatly enhanced.

[0032] According to embodiments of this disclosure, the driving device includes:

[0033] The gear is connected to the shaft at the top of the air guide;

[0034] A rack that meshes with the gear;

[0035] A limiting part is provided in the receiving part, extending along the length direction of the housing, and the end of the rack away from the gear is slidably connected to the limiting part;

[0036] A drive component is installed in the housing. The drive component is connected to the rack and is used to drive the rack to translate along the length of the housing. The movement of the rack drives the meshing gear to rotate, thereby driving the air guide to rotate.

[0037] The above technical solution has the following advantages or beneficial effects: by driving the drive component to mesh with the rack to drive multiple air guides to rotate, it is possible to control the rotation of several air guides with fewer drive components, which simplifies the structure of the drive device, reduces the cost, improves the reliability and stability of the drive device, and can realize at least some of the synchronous movement of several air guides.

[0038] According to an embodiment of this disclosure, the driving component is mounted on a fixed plate, and the bottom of the fixed plate is fixedly connected to the rotating shaft at one end of the air outlet frame. The rotation of the air outlet frame drives the driving component to rotate synchronously.

[0039] The above technical solution has the following advantages or beneficial effects: by mounting the drive component on the fixed plate, it rotates synchronously with the air outlet frame, ensuring that the drive component can still work normally when the air outlet frame is in different positions, and realizing precise control of the air guide component.

[0040] According to an embodiment of this disclosure, the top of the air outlet frame is provided with a receiving portion for accommodating the rack and the gear, and the rotating shaft at the top of the air guide extends into the receiving portion and connects with the gear.

[0041] The above technical solution has the following advantages or beneficial effects: by setting up a receiving part, a relatively independent and stable space is provided for the gear and rack, which is conducive to protecting the gear and rack and preventing them from being disturbed or damaged by the outside world. At the same time, it is also convenient to connect and assemble the gear and the air guide, ensuring that the drive device can stably drive the air guide to rotate.

[0042] According to embodiments of this disclosure, the driving component includes:

[0043] The drive motor is fixed to the fixed plate;

[0044] A guide portion is connected to the bottom of one end of the rack, and the guide portion is provided with a groove extending along the axial direction of the rotating shaft;

[0045] The rotating arm has one end connected to the motor shaft of the drive motor, and the other end slidably connected to the slide groove via a rotating shaft that extends along the thickness direction of the air outlet frame.

[0046] The above technical solution has the following advantages or beneficial effects: the drive component adopts a combination design of drive motor, guide and rotating arm, which can realize the translational movement of rack and pinion, thereby driving gear and air guide to rotate. The structure is simple and compact, the motion transmission is flexible, and it is easy to accurately control the rotation angle of air guide, thus improving the accuracy and convenience of air outlet direction adjustment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0069] The wall-mounted air conditioner indoor unit 100 provided in this utility model embodiment can have various implementation forms, as detailed below. Figures 1-17 The indoor unit 100 of the air conditioner is described.

[0070] It should be noted that the indoor unit 100 of the wall-mounted air conditioner is part of the air conditioner. The indoor unit 100 is installed indoors and is used for heat exchange with the indoor environment. In addition, the air conditioner also includes an outdoor unit, which is usually installed outdoors and is used to carry heat from indoors to outdoors.

[0071] refer to Figure 1 In one illustrative embodiment of the wall-mounted air conditioner indoor unit 100 provided by this utility model, the wall-mounted air conditioner indoor unit 100 may include a housing 1. The housing 1 is installed indoors, and the housing 1 forms the overall appearance of the wall-mounted air conditioner indoor unit 100.

[0072] The housing 1 is roughly rectangular in shape, with the left and right ends of the housing 1 being opposite each other along its length.

[0073] The housing 1 has a top end and a bottom end, which are opposite ends of the housing 1 in the height direction. The front side and the rear side of the housing 1 are opposite sides in the thickness direction.

[0074] The housing 1 is located at the top of the room or in the upper space of the room. The front of the housing 1 faces the user and the rear of the housing 1 faces the wall, making it suitable for connection with the wall.

[0075] The casing 1 has an internal accommodating space. This space is used to house and fix various components in the wall-mounted air conditioner indoor unit 100, which can prevent external objects from colliding with the various components inside the casing 1, thereby improving the reliability of the wall-mounted air conditioner indoor unit 100 during transportation or installation.

[0076] In some embodiments of this application, reference is made to Figure 2 The housing 1 may include an air conditioning inlet 3.

[0077] The air conditioning inlet 3 is connected to the housing space. As the inlet for external air to flow into the casing 1, the air conditioning inlet 3 allows indoor air to enter the housing space through the air conditioning inlet 3.

[0078] In some embodiments of this application, reference continues to be made to Figure 2 The housing 1 may include an air conditioning vent 2.

[0079] The air conditioner outlet 2 is connected to the housing space. The air conditioner outlet 2 serves as the outlet 103 for airflow to flow out of the housing 1, allowing the airflow in the housing space to flow out to the indoor environment through the air conditioner outlet 2.

[0080] The air inlet 3 can be located at the top of the housing 1. The air outlet 2 can be located at the front of the housing 1 and near the bottom of the housing 1, that is, the air outlet 2 is located at the bottom front of the housing 1. In this embodiment, when the indoor unit of the air conditioner is working, the indoor unit 100 takes in air from the top and exits air to the front, which is convenient for installation.

[0081] Among them, the air conditioner outlet 2 is long and narrow, and the air conditioner outlet 2 can be extended along the length of the casing 1. This design improves the aesthetics of the wall-mounted air conditioner indoor unit 100.

[0082] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include an indoor heat exchanger.

[0083] The indoor heat exchanger extends along the length of the casing 1 and is located in the housing space inside the casing 1 for heat exchange with the airflow inside the casing 1.

[0084] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include a heat exchange fan.

[0085] The heat exchange fan is installed in the housing 1 and is used to drive the indoor air outside the housing 1 into the housing 1 through the air inlet. The heat exchange fan drives the air in the housing to flow along the air inlet 3 towards the air outlet 2.

[0086] The heat exchange fan can be a cross-flow fan, located below the indoor heat exchanger. To improve heat exchange efficiency, the indoor heat exchanger is partially enclosed by the heat exchange fan, effectively increasing the heat exchange area.

[0087] The heat exchange fan is positioned near the air conditioner outlet 2, while the indoor heat exchanger is positioned near the air conditioner inlet 3, relative to the heat exchange fan. In other words, in the airflow direction within the casing 1, the heat exchange fan is downstream of the indoor heat exchanger.

[0088] When the indoor unit 100 of the wall-mounted air conditioner is running, driven by the heat exchange fan, indoor air enters the containment space through the air conditioner inlet 3. The indoor air in the containment space flows through the indoor heat exchanger for heat exchange. The air after heat exchange is discharged to the outside through the air conditioner outlet 2, thereby enabling the air conditioner to cool and heat, play a role in regulating the indoor temperature, and achieve the user's comfortable temperature.

[0089] In some embodiments of this application, the wall-mounted air conditioner indoor unit 100 may include an air inlet grille.

[0090] The air intake grille is located at the air conditioning inlet 3 to prevent larger impurities from entering the containment space.

[0091] In some embodiments of this application, the indoor unit 100 of the wall-mounted air conditioner may include an air inlet filter, which is disposed between the air inlet grille and the indoor heat exchanger to filter indoor air and improve air quality.

[0092] An outdoor unit for an air conditioner may include an outdoor unit housing. The outdoor unit housing may contain an installation cavity.

[0093] The outdoor unit housing may include an outdoor air inlet. The outdoor air inlet may communicate with the mounting cavity. The outdoor air inlet can be used to introduce outdoor air into the mounting cavity.

[0094] The outdoor unit housing may include an outdoor air outlet. The outdoor air outlet may communicate with the mounting cavity. The outdoor air outlet can be used to exhaust air from inside the mounting cavity to the outside of the mounting cavity.

[0095] An outdoor unit for an air conditioner may include an outdoor heat exchanger. The outdoor heat exchanger may be located inside an installation cavity.

[0096] An outdoor unit for an air conditioner may include an outdoor fan. The outdoor fan may be installed inside the mounting cavity.

[0097] The rotation of the outdoor fan causes outdoor air to enter the installation cavity through the outdoor air inlet and exchange heat with the outdoor heat exchanger. After heat exchange, the outdoor air flows out of the installation cavity through the outdoor air outlet.

[0098] An air conditioner may include a compressor. The compressor is located within the mounting cavity.

[0099] Air conditioners may include a throttling device. The throttling device is used to limit airflow. The throttling device may be provided in the indoor unit 100 or the outdoor unit of a wall-mounted air conditioner.

[0100] Air conditioners execute a refrigeration cycle using a compressor, condenser, throttling device, and indoor heat exchanger. The refrigeration cycle involves a series of processes including compression, condensation, expansion, and evaporation, supplying refrigerant to the conditioned and heat-exchanged air.

[0101] The compressor compresses the refrigerant gas at low temperature and low pressure and discharges it at high temperature and high pressure. The discharged refrigerant gas flows into the condenser.

[0102] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released into the surrounding environment through the condensation process.

[0103] The throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0104] The refrigerant that expands in the throttling device evaporates in the indoor heat exchanger and returns the refrigerant gas, which is in a low temperature and low pressure state, to the compressor.

[0105] Indoor heat exchangers achieve a 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.

[0106] Of the two heat exchangers, one is a condenser and the other is an indoor heat exchanger. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in heating mode. When the indoor heat exchanger is used as an indoor heat exchanger, the air conditioner is used as a cooler in cooling mode.

[0107] In some embodiments of this application, the indoor unit 100 of the wall-mounted air conditioner may include an air guide structure. This air guide structure is located at the air outlet of the air conditioner and is used to guide the airflow within the casing 1 outwards.

[0108] refer to Figure 1 and Figure 4 The air guiding structure may include several air guiding components 4. Several air guiding components 4 are arranged at intervals along the length of the housing 1 at the air conditioning outlet 2, and the air guiding components 4 are rotatable relative to the housing 1.

[0109] In this embodiment, several air guides 4 are evenly spaced along the length of the casing 1 at the air conditioner outlet 2.

[0110] Through the coordinated action of multiple air guides 4, the airflow direction can be controlled more flexibly, achieving a wider air outlet range, meeting the needs of different users for air outlet angle and direction, and improving the user experience.

[0111] refer to Figure 1 and Figure 15 The air guide 4 may include a rotating shaft 42. The rotating shaft 42 provides stable rotational support for the air guide 4, ensuring that the air guide 4 can achieve the expected rotational effect, thereby precisely controlling the airflow direction.

[0112] The axial direction of the rotating shaft 42 is the same as the axial direction of the rotating shaft 61 of the air guide 4. The axial direction of the rotating shaft 42 is perpendicular to the length direction of the housing 1. This arrangement allows the rotation of the air guide 4 to determine the airflow direction along the length of the housing 1 and change the flow path area.

[0113] The air guide structure may include a drive device 5, which is connected to the rotating shaft 42 to drive the air guide 4 to rotate.

[0114] By setting up the drive device 5, the air guide component 4 can be automatically controlled, and the user does not need to manually adjust the air guide component 4, making the operation more convenient.

[0115] Understandably, the drive unit 5 can precisely control the rotation angle and speed of the air guide 4 according to a preset program or user instructions, thereby improving the accuracy and stability of the airflow.

[0116] refer to Figure 1 , Figure 3 and Figure 15 The air guide 4 has an internally defined air guide channel 41 with an air outlet axis 411. The air guide channel 41 is configured to guide the airflow inside the housing 1 out of the housing 1 along the extension direction of the air outlet axis 411.

[0117] In this embodiment, several air guides 4 with air guide channels 41 are rotatably arranged at the air outlet 2 of the air conditioner. By rotating the air guides 4, the outflow direction of the airflow is determined and the flow path area of ​​the air guide channel 41 is changed. Various airflows can be selectively generated to have multiple airflow outlet modes, thereby increasing the airflow range, softening the airflow feel, and balancing the airflow speed. This makes the airflow outlet more diversified and improves the applicability and flexibility of the wall-mounted air conditioner indoor unit 100.

[0118] refer to Figure 7 , Figure 10 When the air guide 4 rotates to the first position where its own air outlet axis 411 is parallel to the length direction of the casing 1, the air conditioner air outlet 2 of the part blocked by the air guide 4 is blown out through the gap between the air guide 4.

[0119] When the air guide 4 rotates to the first position, the air outlet axis 411 of the air guide channel 41 is perpendicular to the airflow output by the heat exchange fan. Due to the obstruction of the air guide 4, the airflow is forced to change direction and flows out through the gaps between the air guides 4. These gaps are small in size and evenly distributed, so that the airflow is dispersed and guided into multiple fine airflows when it flows out, forming a diffused airflow path.

[0120] At the outlet of the diffused airflow path, the air outlet area increases rapidly. According to fluid dynamics principles, when airflow enters a wider channel from a narrower one, its speed decreases, and it diffuses outwards. As the airflow exits through the diffused airflow path, it spreads out more gently and evenly, reducing wind speed and volume to achieve a windless effect and avoiding the discomfort that might be caused by strong winds blowing directly on the body. This windless airflow mode is suitable for scenarios where direct airflow needs to be avoided, such as sleep mode or in situations with infants or the elderly, improving user comfort.

[0121] refer to Figure 5 , Figure 8 When the air guide 4 rotates to the second position where its own air outlet axis 411 is perpendicular to the length direction of the casing 1, the airflow is blown forward from the air guide channel 41.

[0122] When the air guide 4 is rotated to the second position, the air outlet axis 411 is parallel to the airflow output by the heat exchange fan, so that the airflow passes through the air guide channel 41 almost unobstructed, blowing out with minimal resistance and unaffected by deflection, enabling the airflow to be delivered directly to a relatively long distance. This air outlet mode is suitable for scenarios that require rapid adjustment of indoor temperature, such as during initial cooling or heating, and can quickly deliver the cooled or heated air after heat exchange to the room.

[0123] refer to Figure 6 , Figure 9 When the air guide 4 rotates to the position between the first and second positions of its own air outlet axis 411, the airflow is blown out at an angle from the air guide channel 41.

[0124] When the air guide 4 rotates to between the first and second positions, the air guide channel 41 deflects, causing the airflow direction to change and expanding the airflow range in the left and right directions. This air outlet mode is suitable for scenarios that require airflow to be delivered to a wider area, which helps to increase the coverage area of ​​the air conditioner outlet and make the indoor temperature distribution more uniform.

[0125] In some embodiments of this application, reference is made to Figure 3 , Figure 4 The air guiding structure may include an air outlet frame 6, which is located at the air outlet 2 of the air conditioner.

[0126] The air outlet frame 6 is rotatably connected to the housing 1, and several air guide components 4 are rotatably connected to the air outlet frame 6.

[0127] The rotating connection design of the air outlet frame 6 allows the air guide 4 to move together with the air outlet frame 6, enhancing the integrity and coordination of the air outlet structure and improving the flexibility of air guidance.

[0128] refer to Figure 12 The rotation axis of the air outlet frame 6 extends along the length of the housing 1.

[0129] The two ends of the air outlet frame 6 along its length are rotatably connected to the housing 1 via a rotating shaft 61, allowing the air outlet frame 6 to rotate up and down, flexibly adjusting the air outlet direction, expanding the air guiding range, and meeting the comfort needs of different users.

[0130] The air guide structure may include a rotating motor, which is located inside the housing 1. The rotating motor can be connected to a rotating shaft 61 at one end of the air outlet frame to drive the air outlet frame 6 to rotate.

[0131] In this embodiment, the length of the air outlet duct can be extended by setting the air outlet frame 6, and the rotation adjustment of the air conditioning air outlet duct is also increased so that the length and angle of the air outlet duct can be adjusted according to the installation and use environment.

[0132] Meanwhile, the air outlet frame 6, together with the air guide 4, can achieve multi-angle and all-round air supply adjustment of the air outlet angle of the air conditioner vent 2, which can realize a wider air supply range and a more flexible air supply mode. It can effectively solve the technical problem that the air supply direction adjustment of the traditional wall-mounted air conditioner indoor unit 100 can usually only be carried out on a single plane, which makes it difficult to meet the user's requirements for multi-angle and all-round air supply.

[0133] In some embodiments of this application, reference is made to Figure 15 The air guide 4 may include two guide plates 43. The two guide plates 43 are arranged opposite each other and spaced apart along a direction perpendicular to the air outlet axis 411.

[0134] The two guide plates 43, positioned opposite each other, work together to effectively guide and constrain airflow. When the air guide 4 rotates, the angle and position range of the guide plates 43 is greater than that of traditional air guide vanes, further improving the flexibility, precision, and comfort of the air conditioning system.

[0135] For example, refer to Figure 6 During the airflow process, the guide plate 43 will be in different positions relative to the airflow direction. These positions can be divided into the upstream guide plate 431 position and the downstream guide plate 432 position.

[0136] By adjusting the angle and position of the upstream guide plate 431 and the downstream guide plate 432, the wind direction guiding surface in the air guide channel 41 is lengthened to a certain extent, which extends the path for adjusting the direction of the airflow and expands the air delivery distance and air delivery coverage.

[0137] Continue to refer to Figure 6 The airflow entering the air guide channel 41 first contacts the upstream guide plate 431 and changes direction. The airflow flowing out of the air guide channel 41 is then further guided by the downstream guide plate 432. This increases the "effective length" of the entire airflow guidance process, thereby enabling more precise control of the direction and distribution of the airflow.

[0138] When the airflow passes through the air guide channel 41, by reasonably setting the angle and position of the guide plate 43, the guide plate 43 can sort and adjust the airflow, which helps to avoid the local airflow speed being too fast or too slow, making the airflow speed of the entire air conditioning outlet 2 more uniform and improving the comfort of the human body.

[0139] The air guide 4 may include a fixing plate 44. Two fixing plates 44 are configured, positioned opposite each other at the top and bottom ends of the guide plate 43. (See reference) Figure 15 Two fixed plates 44 and two guide plates 43 enclose each other to form an air guide channel 41.

[0140] In this embodiment, the fixing plate 44 is disposed opposite to the top and bottom of the guide plate 43, which plays a role in stabilizing the guide plate 43 and ensuring the stability and reliability of the structure of the air guide 4.

[0141] Continue to refer to Figure 15 The rotating shaft 42 is vertically mounted on the fixed plate 44, and one of the rotating shafts 42 on the two fixed plates 44 is connected to the drive device 5. Among them, the rotating shaft 42 at the top of the air guide 4 is connected to the drive device 5.

[0142] The rotating shaft 42 on the fixed plate 44 provides a reliable path for the rotational power transmission of the air guide 4, ensuring that the drive device 5 can effectively drive the air guide 4 to rotate through the rotating shaft 42, thereby realizing the automated control of the air guide 4.

[0143] In some embodiments of this application, the cross-section of the guide plate perpendicular to the axis of rotation is arc-shaped or straight. The cross-section of the guide plate perpendicular to the axis of rotation is the cross-section of the guide plate.

[0144] refer to Figure 5 The guide plate 43 has a straight cross-section. The extension direction of the straight guide plate 43 is parallel to the direction of the air outlet axis 411. The extension direction of the straight guide plate 43 is perpendicular to the axis of the rotating shaft 42.

[0145] refer to Figure 6 The guide plate 43 has an arc-shaped cross-section. The guide plate can be a circular arc plate, and the center of the arc can be located on the axis of the rotating shaft 42.

[0146] In this embodiment, the cross-section of the guide plate 43 is arc-shaped or straight, which makes the shape of the air guide channel 41 more in line with the aerodynamic principle, making the airflow in the air guide channel 41 smoother, reducing airflow resistance and turbulence, thereby improving air delivery efficiency, enhancing the uniformity and stability of airflow, and improving user comfort.

[0147] In some embodiments of this application, the outline of the guide plate 43 is curved in a cross section perpendicular to the axis of the rotating shaft 42. The curve of the outline of the guide plate 43 is a multi-segment curve, and the multiple segments of the multi-segment curve can be continuous curve segments or straight line segments, which can meet more complex airflow control requirements.

[0148] By setting the contour curve of the guide plate 43 to a multi-segment curve, the guide plate 43 can exert different guiding and constraining effects on the airflow at different positions, thereby achieving more precise airflow regulation.

[0149] It should be noted that a straight line can be considered a special type of curve, and multiple curve segments can include straight line segments.

[0150] The contour line of the guide plate 43 is set with multiple curves, which can deflect and diffuse the airflow multiple times before reaching the user's position, reduce the impact of the airflow, reduce the feeling of direct blowing, and avoid blowing towards a specific area or concentrated blowing towards a specific position, thereby improving the user's comfort.

[0151] refer to Figure 11 The outline of the guide plate 43 is a multi-segment curve formed by connecting two straight lines. The guide plate 43 adopts a gradually expanding straight section at the entrance of the air guide channel 41, so that the airflow can enter the air guide channel 41 smoothly and reduce airflow resistance and noise; at the exit of the air guide channel 41, a gradually narrowing straight section is adopted, so that the airflow can flow out in a concentrated manner and improve the accuracy and intensity of air delivery.

[0152] In some embodiments of this application, the guide plate 43 may include a first guide section 433. One end of the first guide section 433 is located at the inlet end of the air guide channel.

[0153] The first guide section 433, as part of the guide plate 43, can play a preliminary guiding role in the airflow, so that the airflow flows in a predetermined direction.

[0154] The guide plate 43 may include a second guide section 434, and the first guide section 433 and the second guide section 434 are arranged along the air outlet axis 411.

[0155] The second guide section 434 and the first guide section 433 are arranged along the air outlet axis 411, which further refines and optimizes the airflow path, enabling more precise control of the airflow direction and distribution, and improving the accuracy and comfort of air delivery.

[0156] refer to Figure 11 The first guide segment 433 and the second guide segment 434 are connected at an angle, with the angle pointing towards the opposite guide plate 43. In this embodiment, the angle can be an obtuse angle.

[0157] By setting the first guide section 433 and the second guide section 434, the airflow is more significantly deflected and diffused under the action of the air guide, thereby expanding the airflow range, softening the airflow feel, balancing the airflow speed, and improving user comfort.

[0158] In some embodiments of this application, reference is made to Figure 8 The air guide channel 41 has a tendency to first expand and then shrink in the cross section perpendicular to the axis of the rotating shaft 42.

[0159] In a cross-section perpendicular to the axis of rotation 42, the air guide channel 41 has a tendency to first gradually expand and then gradually narrow, causing the air path at the inlet of the diffused air path to gradually narrow and the outlet to gradually widen. When the airflow passes through the diffused air path, the gradual narrowing at the inlet increases the airflow velocity, while the gradual widening at the outlet decreases the airflow velocity. At the same time, the rapid expansion of the diffused air path causes the airflow to diffuse, thereby making the velocity distribution of the airflow more uniform.

[0160] In some embodiments of this application, the two guide plates 43 of the air guide 4 are symmetrically arranged along the axial direction of the rotating shaft 42. The guide plate 43 is an arc plate with its arc center located within the air guide channel 41, and the arc centers of the two guide plates 43 of the same air guide 4 can be located along the axial direction of the rotating shaft 42.

[0161] In some embodiments of this application, the minimum distance between two guide plates 43 that are close to each other on two adjacent air guides 4 is less than the distance between the guide plate 43 and the axis of the rotating shaft 42.

[0162] In this embodiment, by setting the minimum distance between adjacent guide plates 43 of the air guide 4 to be as close as possible, the positional deviation of the upstream guide plate 431 and the downstream guide plate 432 in the airflow direction is maximized when the air guide 4 rotates between the first position and the second position, significantly enhancing the ability to deflect the airflow direction. At the same time, the airflow guiding surface can be lengthened in the airflow direction, greatly enhancing the effect of bending the airflow direction.

[0163] In some embodiments of this application, the drive device 5 may include a gear 52, which is connected to the shaft 42.

[0164] Among them, there are several gears 52, and each gear 52 is installed on the top of the rotating shaft 42 of several air guides 4.

[0165] The drive device 5 may include a rack 51, which meshes with a gear 52.

[0166] refer to Figure 16 The rack 51 extends along the length of the housing 1. The rack 51 moves relative to the housing 1 along the length of the housing 1. The movement can ensure that the air guide 4 moves synchronously and in a coordinated manner in the extension direction of the air outlet 2, thereby improving the accuracy and efficiency of air guidance.

[0167] The rack 51 can be configured as at least one, and the number of racks 51 is less than the number of air guides 4. (Reference) Figure 16 Multiple gears 52 mesh with at least one rack 51.

[0168] The drive unit 5 may include a limiting part 53. (Continue to refer to...) Figure 16The limiting part 53 extends along the length of the housing 1 and is disposed in the receiving part 62, and the end of the rack 51 away from the gear 52 is slidably connected to the limiting part 53.

[0169] The limiting part 53 ensures that the rack moves in a translational motion along the length of the housing 1.

[0170] Furthermore, the drive device 5 may include a drive component 54, which is connected to the rack 51 to drive the rack to translate along the length of the housing 1. The movement of the rack 51 can drive the meshing gear 52 to rotate, thereby driving the air guide 4 to rotate.

[0171] In this embodiment, the number of drive components 54 is configured to be the same as the number of racks 51.

[0172] In this embodiment, the rotation of multiple air guides 4 is driven by at least one driving component 54, which reduces the number of driving components and enables the rotation of several air guides 4 to be controlled by fewer driving motors. This simplifies the structure of the driving device 5, reduces manufacturing costs and complexity, and improves the reliability and stability of the driving device 5. It can also achieve at least partial synchronous movement of several air guides 4.

[0173] refer to Figure 16 In this embodiment, the rotating shafts 42 of several air guides 4 are driven by a driving component 54 through a rack 51. Using a driving component 54 to drive multiple air guides 4 can improve the integration of the driving system.

[0174] In other embodiments, the rotating shafts 42 of the plurality of air guides 4 can also be driven by multiple drive components 54. The flexible configuration of multiple drive components 54 can adapt to different air guiding requirements, enhancing the adaptability and scalability of the system.

[0175] For example, when two drive components 54 are configured, one rack 51 of the two drive components 54 is connected to multiple air guides 4 on the left side of the housing 1, and the other rack 51 is connected to multiple air guides 4 on the right side of the housing 1. The two drive motors in the two drive components 54 are respectively located at the left and right ends of the air conditioning outlet 2.

[0176] By setting the multiple air guides 4 on the right to rotate outward to the right and the multiple air guides 4 on the left to rotate outward to the left, an airflow distribution that avoids the human body can be formed in front, thus providing users with a comfortable air environment without a direct blowing sensation. This setting not only simplifies the drive device 5, but also achieves a personalized air delivery mode through reasonable airflow guidance.

[0177] In some embodiments, reference Figure 14 The drive component 54 may include a drive motor 541, which is installed inside the housing 1.

[0178] The drive component 54 may include a guide portion connected to the bottom of one end of the rack 51. (See reference) Figure 14 The guide section is provided with a slide groove 543 extending along the axis of the rotating shaft 42.

[0179] The drive component 54 may include a rotating arm 542, one end of which is connected to the motor shaft of the drive motor 541, and the other end of which is slidably connected to the slide groove 543 via a rotating shaft 5421. The rotating shaft 5421 extends along the thickness direction of the air outlet frame 6.

[0180] When the drive motor 541 rotates, the rotating arm 542 rotates around the motor shaft. Since the other end of the rotating arm 542 is embedded in the groove 543 at the bottom of the rack 51, the rotational movement of the rotating arm 542 causes its rotating shaft 5421 to slide within the groove 543. When the rotating arm 542 rotates, the movement of its rotating shaft 5421 within the groove 543 generates a component force along the extending direction of the rack 51. This component force pushes or pulls the rack 51, causing it to translate along its extending direction.

[0181] In some other embodiments, the drive component may include a drive motor and a drive gear connected to the drive motor.

[0182] The meshing of the drive gear and the rack 51 ensures the precise transmission of power, enabling the rack 51 to accurately translate under the rotation of the drive gear, thereby precisely controlling the rotation angle and direction of the air guide 4.

[0183] Similarly, the drive motor and the corresponding active gear can provide stable power output, ensuring smooth and precise movement of the rack 51, thereby achieving precise control of the air guide 4.

[0184] The drive motor drives the drive gear to rotate, and the rotation of the drive gear drives the rack 51 to move in translation.

[0185] In some embodiments of this application, the positions of several rotating shafts 42 are projected onto an axial projection plane. The projection points of the several rotating shafts 42 lie on one or more straight lines.

[0186] Multiple air guides 4 are set on each straight line, wherein the number of driving components is less than the number of air guides 4.

[0187] Specifically, multiple air guides 4 can be arranged sequentially along each straight line, and each air guide 4 has its own rotating shaft 42. These air guides 4 can be rotated simultaneously by a common drive component.

[0188] By optimizing the transmission design, multiple air guides 4 can be driven simultaneously with fewer drive components than the number of air guides 4, thereby improving drive efficiency and reducing system complexity.

[0189] It should be noted that the axial projection plane is a plane perpendicular to the axis of rotation 42.

[0190] In some embodiments of this application, when the drive component 54 is connected to the rotating shaft 61 of the air outlet frame 6, the rotation of the rotating shaft 61 drives the drive component 54 to rotate, so that the rotation of the air outlet frame 6 drives several air guides 4 and the drive device 5 to rotate synchronously.

[0191] For details, please refer to Figure 14 The drive component 54 is mounted on the fixed plate 7. The bottom of the fixed plate 7 is fixedly connected to the rotating shaft 61 at one end of the air outlet frame 6. The rotation of the air outlet frame 6 drives the drive component 54 to rotate synchronously.

[0192] It should be noted that in this embodiment, the drive component 54 and the rotating motor are respectively connected to the rotating shafts 61 at both ends of the air outlet frame 6 along the length direction, which avoids mutual interference between the two and facilitates the wiring of the motor.

[0193] In some embodiments of this application, the air outlet frame 6 rotates to open or close the air conditioning outlet 2.

[0194] When the indoor unit 100 of the wall-mounted air conditioner is turned off, the air outlet frame 6 can be rotated to the position where the air outlet 2 is closed, ensuring the aesthetic appearance of the indoor unit 100 of the wall-mounted air conditioner.

[0195] In some embodiments of this application, the top of the air outlet frame 6 is provided with a receiving portion 62, which is used to accommodate the gear 52 and the rack 51.

[0196] By providing the housing 62, a relatively independent and stable space is provided for the gear 52 and the rack 51, which helps to protect the components of the drive unit 5 from external interference and damage. At the same time, it can maintain the neat appearance of the wall-mounted air conditioner indoor unit 100.

[0197] Among them, the rack 51 in the drive device 5 can move relative to the air outlet frame 6 along the length direction of the air outlet frame 6.

[0198] refer to Figure 14 , Figure 15 The top of the air guide 4 has a rotating shaft 42 that extends into the receiving portion 62 and connects to the drive device 5. The receiving portion 62 facilitates the connection and assembly of the drive device 5 with the rotating shaft 42, ensuring that the drive device 5 can stably drive the air guide 4 to rotate.

[0199] In some embodiments of this application, a plurality of air guides 4 are arranged at intervals at the air conditioner outlet 2, and a driving device 5 is connected to the air guides 4 to drive the air guides 4 to rotate.

[0200] When the air guide 4 rotates until its own air outlet axis 411 is parallel to the length direction of the air conditioner outlet 2, the air conditioner outlet 2 is blocked by the air guide 4, and the airflow is discharged through the gap between the air guide 4.

[0201] By rotating the air guide 4 so that the air outlet axis 411 is parallel to the length direction of the air conditioner outlet 2, the air guide 4 diffuses and homogenizes the airflow. The airflow flows out through the gaps between the air guide 4, allowing the airflow to diffuse in a gentler and more uniform manner at the air conditioner outlet 2. This reduces the wind speed and volume to achieve a windless effect, avoiding the discomfort that may be caused by strong winds blowing directly on the human body, and improving user comfort.

[0202] In this embodiment, the rotation of the air guide 4 is used to achieve a windless effect, eliminating the need for additional windless components. This simplifies the air outlet structure of the air conditioner and makes the airflow softer and more uniform. Users can hardly feel the direct airflow, thus improving the comfort of the windless effect.

[0203] It should be noted that the use of "applies to" or "configured to" in this article implies an open and inclusive language, which does not exclude the applicability to or configuration of devices to perform additional tasks or steps.

[0204] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).
