Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to a wall-mounted air conditioner indoor unit and an air conditioner. Background Technology

[0002] In wall-mounted air conditioner indoor units, the air outlet is usually located at the junction of the lower part of the front surface and the front part of the lower surface, and the width of the air outlet is usually a few centimeters to about ten centimeters. However, if the air conditioner has a zero-wind function, or is called a diffuser function, no wind or gentle wind function, then a diffuser panel needs to be installed to block or basically block the air outlet of the air conditioner.

[0003] The air diffuser panel has many small-diameter air vents. When the airflow from the air conditioner encounters the solid part of the diffuser panel, it is dispersed by the solid part. The airflow from the air conditioner can only flow out through the air vents. Because the diameter of the air vents is very small, usually only a few millimeters in size, the airflow passing through the air vents only travels a short distance on the leeward side of the diffuser panel before mixing with the air, thus not forming a noticeable airflow. When the user is indoors, the user can hardly feel the cold air blowing on them.

[0004] Due to the size limitations of the air outlet of the air conditioner, the size of the diffuser is usually similar to that of the air outlet. This results in a small total area of ​​the diffuser holes and a small total cross-sectional area of ​​the airflow channel through the diffuser, which in turn leads to a small airflow. In other words, the airflow under the zero-wind-feel function is small, making it difficult to reach the required temperature quickly. Utility Model Content

[0005] The first objective of this utility model is to provide a wall-mounted air conditioner indoor unit to solve the technical problem of low air volume in the zero-wind mode of existing wall-mounted air conditioner indoor units.

[0006] The first aspect of this utility model provides a wall-mounted air conditioner indoor unit, including a main unit housing, an air outlet cavity, and an air outlet opening / closing module. A heat exchange cavity is formed inside the main unit housing; an air outlet cavity is formed inside the air outlet cavity, and the heat exchange cavity is connected to the air outlet cavity through an internal air supply port. The wall panel of the air outlet cavity opposite to the internal air supply port is a diffuser plate, and the diffuser plate has diffuser holes that penetrate along the thickness direction of the plate and an external air outlet. The air outlet opening / closing module includes a guide cover for opening and closing the external air outlet, and the guide cover is movably arranged opposite to the diffuser plate.

[0007] The beneficial effects of this wall-mounted air conditioner indoor unit are:

[0008] By designing the wall panel opposite the internal air outlet of the air outlet cavity as a diffuser, the area of ​​this wall panel is significantly larger than the air outlet area of ​​a traditional wall-mounted air conditioner indoor unit. This allows for the placement of diffuser holes over a larger area, resulting in a larger airflow while maintaining the same density, size, and other conditions, thus improving the speed of temperature regulation. Furthermore, the inclusion of an air outlet opening / closing module to open the external air outlet allows the airflow entering the air outlet cavity from the internal air outlet to be directly discharged from the external air outlet in direct-blow mode. This enables the use of a larger airflow to regulate the indoor temperature in direct-blow mode.

[0009] In an optional technical solution, when the outlet air vent is opened, the air guide cover is configured to be located on one side of the main body of the outlet airflow and to guide the main body of the outlet airflow.

[0010] This design allows the air deflector to control the direction of the airflow, ensuring that when the air conditioner is in heating mode, the hot air blown out is directed downwards, while when it is in cooling mode, the cold air is directed forwards or upwards, thus improving the temperature uniformity of the indoor environment.

[0011] In an optional technical solution, the air outlet opening and closing module includes a telescopic mechanism and a rotating mechanism. The rotating mechanism is connected to the air guide cover and is installed at the power output end of the telescopic mechanism. The telescopic mechanism is used to drive the rotating mechanism to approach and move away from the heat exchange chamber.

[0012] By setting up telescopic and rotating mechanisms to drive the air guide cover, the air guide cover can be pushed outward to the air outlet, with its normal direction located on both sides of the normal direction of the air outlet. This not only allows the hot air from the wall-mounted air conditioner indoor unit to blow downward, but also allows the cold air to blow forward and downward, improving the air conditioner's ability to control the air outlet direction in different modes. This, in turn, improves the uniformity of indoor space temperature during cooling or heating, and enhances the user experience.

[0013] In an optional technical solution, the telescopic mechanism includes a telescopic member and a telescopic drive assembly. The telescopic drive assembly is connected to the telescopic member and is used to drive the telescopic member in directions away from and towards the heat exchange cavity. The telescopic member is equipped with the rotating mechanism.

[0014] By setting up telescopic components to drive the rotation mechanism to extend and retract, the number of parts in the air outlet cavity can be reduced and the complexity of the shape can be decreased, thereby weakening the interference of the telescopic mechanism in the air outlet cavity on the airflow.

[0015] In an optional technical solution, the rotating mechanism includes a rotating drive and a rotating swing arm. The rotating swing arm is fixedly connected to the air guide cover, and the rotating drive is driven to rotate the rotating swing arm outside the air outlet.

[0016] By setting a rotating swing arm that is fixedly connected to the air guide cover, the rotation axis of the air guide cover can be separated from the air guide cover, thereby increasing the range of motion that the air guide cover can move when swinging. This makes it easier for the air guide cover to move to the position that guides the main body of the airflow, so that hot air can blow downwards as much as possible and cold air can blow forward as much as possible, thereby improving the temperature uniformity of the indoor space.

[0017] In an optional technical solution, the outlet air vent is located at the middle of the air diffuser in the width direction.

[0018] Typically, the internal air outlet is located in the middle of the air outlet cavity width. When the indoor unit of the wall-mounted air conditioner is in direct-blow mode, the outdoor air outlet can be directly opposite the internal air outlet. This allows the airflow entering the air outlet cavity from the internal air outlet to reach the outdoor air outlet through the shortest path, reducing the loss of airflow in the air outlet cavity in direct-blow mode and increasing the air volume.

[0019] In an optional technical solution, multiple air conditioning fans are arranged in the heat exchange chamber along the left and right direction, and the internal air outlets are arranged in a one-to-one correspondence with the air conditioning fans. The length range of the external air outlets is greater than or equal to the distribution range of the internal air outlets.

[0020] By setting the length range of the outgoing air vents to be greater than or equal to the distribution range of the internal air vents, the air supplied from the internal air vents to the air outlet cavity can be discharged from the outgoing air vents through the shortest path, thereby reducing the loss of airflow in the air outlet cavity and increasing the air volume.

[0021] In an optional technical solution, when the external air vent is closed, the side of the air guide cover facing the internal air vent is provided with left and right sweeping blades.

[0022] This setting allows the air outlet to swing left and right in direct-blowing mode, or to change the direction of the air outlet within the left and right range, so as to deliver air to a wider area of ​​the indoor space, improve temperature uniformity, and enhance the user experience.

[0023] In an optional technical solution, the left and right side walls of the air outlet cavity are arc-shaped side walls, which extend along an arc around the inner air outlet.

[0024] This configuration ensures that the distance between the air diffuser holes at the left and right edges of the air outlet cavity and the inner air outlet is similar, thereby achieving uniform airflow from multiple circumferential positions relative to the inner air outlet. This improves the uniformity of airflow from the air diffuser holes and makes more effective use of the air diffuser holes to improve the overall airflow volume.

[0025] The second objective of this utility model is to provide an air conditioner that solves the technical problem of low air volume in the zero-wind mode of the indoor unit of a wall-mounted air conditioner.

[0026] The air conditioner provided in the second aspect of this utility model includes a wall-mounted indoor unit and an outdoor unit of the air conditioner, as described above, wherein the outdoor unit is connected to the wall-mounted indoor unit via a refrigerant connection pipe.

[0027] By installing the aforementioned wall-mounted air conditioner indoor unit in the air conditioner, the air conditioner accordingly possesses all the advantages of the aforementioned wall-mounted air conditioner indoor unit, which will not be elaborated upon here. Attached Figure Description

Detailed Implementation

[0044] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0045] In this embodiment, a wall-mounted air conditioner indoor unit is used as an example, but this does not preclude the application of the product to a cabinet-type air conditioner indoor unit. Unless otherwise specified, the definitions of direction in this application are as follows: "Front" refers to the side of the wall-mounted air conditioner indoor unit facing the main indoor space, while "rear" refers to the side facing the wall on which it is mounted. "Below" refers to the side of the wall-mounted air conditioner indoor unit facing the ground. "Above" refers to the side of the wall-mounted air conditioner indoor unit facing the ceiling. "Left" and "right" can be defined based on the aforementioned front, rear, and below; that is, when an observer faces the wall where the wall-mounted air conditioner indoor unit is installed, the observer's left hand is the left side, and the observer's right hand is the right side. Furthermore, "inner" and "outer" are defined based on the shape of the component, which is a cavity, box, or cylinder. The side of the cavity, box, or cylinder facing its internal space is the inner side, and the outer side is the side of the cavity or box facing its external space.

[0046] Example 1:

[0047] Figure 1 This is a schematic diagram of the structure of the indoor unit of the wall-mounted air conditioner provided in Embodiment 1 of this utility model. In the diagram, the outdoor air vent is in a closed state. Figure 2 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, viewed from another direction. Figure 3 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model when the air guide cover is opened to allow the outside air vent to be exposed. Figures 1-3 As shown, the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model includes a main unit housing 100, an air outlet cavity 200, and an air outlet opening / closing module 300. A heat exchange cavity 110 is formed inside the main unit housing 100; an air outlet cavity is formed inside the air outlet cavity 200, and the heat exchange cavity 110 is connected to the air outlet cavity through an internal air supply port 151. The wall panel of the air outlet cavity 200 opposite to the internal air supply port 151 is a diffuser plate 210. The diffuser plate 210 is provided with a diffuser hole 211 that penetrates along the thickness direction of the plate, and the diffuser plate 210 is provided with an external air outlet 212. The air outlet opening / closing module 300 includes a guide cover 310 for opening and closing the external air outlet 212, and the guide cover 310 and the diffuser plate 210 are movably arranged relative to each other.

[0048] By setting the wall panel opposite the internal air outlet 151 of the air outlet cavity 200 as a diffuser plate 210, the area of ​​this wall panel of the air outlet cavity 200 is significantly larger than the air outlet area of ​​a traditional wall-mounted air conditioner indoor unit. Therefore, diffuser holes 211 can be set in a larger area, thereby obtaining a larger air volume and improving the speed of temperature regulation while keeping the density, size and other conditions of the diffuser holes 211 unchanged. Furthermore, by setting the air outlet opening and closing module 300 to open the external air outlet 212, the airflow entering the air outlet cavity from the internal air outlet 151 can be directly discharged from the external air outlet 212 in direct-blow mode. This achieves temperature regulation of the indoor environment space with a larger air volume in direct-blow mode.

[0049] For example, taking a 1-horsepower or 1.5-horsepower air conditioner as an example, the width of the air outlet of a traditional wall-mounted air conditioner indoor unit is usually 5 to 8 centimeters, rarely exceeding 10 centimeters. Therefore, the area where the air vent 211 of a traditional wall-mounted air conditioner indoor unit can be set is this width multiplied by the length of the air outlet. Even if the edge of the air outlet is close to the side wall of the front surface of the air conditioner, transmission and drive components are still needed for the rotation of the traditional air guide plate, which still occupies space in the left and right directions. Moreover, it is difficult for the length of the air outlet of a traditional wall-mounted air conditioner indoor unit to be almost equal to the length of the wall-mounted air conditioner indoor unit. This application, by setting the air diffuser holes 211 on the air diffuser plate 210 of the air outlet cavity 200, allows the air diffuser holes 211 to be distributed in the area of ​​the air diffuser plate 210 other than the air outlet 212. Therefore, the width of the area where the air diffuser holes 211 are set can be about 30 centimeters. Moreover, because a separate air outlet cavity is set, the length of the wall panel of the air outlet cavity 200 opposite to the internal air supply port 151 can be almost equal to the length of the wall-mounted air conditioner indoor unit. Under the condition that the distribution density, size and other conditions of the air diffuser holes 211 remain unchanged, a larger air volume can be obtained.

[0050] Specifically, in this embodiment, the air outlet cavity 200 is located in front of the main unit housing 100, that is, the heat exchange cavity 110 is located behind the air outlet cavity. Specifically, the front wall panel of the air outlet cavity 200 is a diffuser plate 210. The heat exchange cavity 110 is separated from the air outlet cavity by a partition plate 150 at the front of the heat exchange cavity 110. The main unit housing 100 has air inlets 120 at its top and bottom, and an indoor heat exchanger 130 is located inside the main unit housing 100, i.e., in the heat exchange cavity 110. In this embodiment, the indoor heat exchanger 130 can be a V-shaped heat exchanger with a forward-opening design. Air entering the heat exchange cavity 110 from the air inlet 120, after heat exchange with the indoor heat exchanger 130, can be drawn in by the air conditioning fan 140.

[0051] In this embodiment, the air conditioning fan 140 is located at the front of the heat exchange chamber 110 and installed on the partition plate 150. The air conditioning fan 140 can be an axial flow fan, a mixed flow fan, or a vortex fan, with the axis of these fans arranged along the front-to-back direction. In this embodiment, two fans of the above types can be arranged along the left-to-right direction, and the internal air outlet 151 on the partition plate 150 is correspondingly arranged with the aforementioned fans, and its shape can be circular. Alternatively, in another implementation, a cross-flow fan can be used, with the axis of the cross-flow fan in the left-to-right direction, and the internal air outlet 151 on the partition plate 150 can be rectangular or rounded rectangles, with the length of the rectangle or rounded rectangle being similar to the length of the impeller of the cross-flow fan. The air guide cover 310 may or may not have a diffuser hole 211. In this embodiment, it is preferable not to have a diffuser hole 211.

[0052] In this embodiment, all ventilation holes 211 are circular. Of course, in other implementations, the ventilation holes 211 can be other shapes, such as rectangles, rhombuses, or rounded rectangles or rounded rhombuses. The ventilation holes 211 can be arranged in columns, with each column of ventilation holes 211 projected horizontally into an adjacent column. More specifically, the ventilation holes 211 can be located at the midpoint between two adjacent ventilation holes 211. Furthermore, three adjacent ventilation holes 211 can be arranged in an equilateral triangle.

[0053] Unless otherwise specified, this embodiment describes the air outlet cavity 200 as being located at the front of the main unit housing 100. Alternatively, in another implementation, the air outlet cavity 200 can be located below the main unit housing 100, in which case an internal air inlet 151 is provided at the bottom of the main unit housing 100 to connect to the air outlet cavity. That is, the bottom wall of the air outlet cavity 200 is a diffuser plate 210. In this implementation, an air inlet 120 is provided on the top or upper front surface of the main unit housing 100, and most of the indoor heat exchanger 130 is located above the air conditioning fan 140. After air enters through the air inlet 120 on the top or upper front surface of the main unit housing 100, it exchanges heat with the indoor heat exchanger 130 in the heat exchange cavity 110 and is then drawn by the air conditioning fan 140 into the air outlet cavity through the internal air inlet 120. If the air conditioner is in cooling mode, the outdoor air vent 212 can be closed, allowing the cold air to be discharged from the air outlet 200 through the air vent 211 in zero-air mode. Since the air outlet 200 has a large area and a large number of air outlets, it can generate a large air volume to meet the cooling needs.

[0054] Furthermore, it should be noted that when the air guide cover 310 opens the outlet air vent 212, although the diffuser plate 210 is provided with diffuser holes 211, and the airflow may be discharged from the diffuser holes 211, the resistance of the outlet air vent 212 after it is opened by the air guide cover 310 is less than, or even much less than, the sum of the resistances of the airflow if it were only discharged from all the diffuser holes 211. Therefore, the airflow is mainly, or even almost entirely, discharged from the outlet air cavity through the outlet air vent 212, with only a very small amount of airflow being discharged from the diffuser holes 211 of the diffuser plate 210.

[0055] Figure 4 This is a side sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, with the air guide cover open and the air outlet pointing forward and downward. Figure 5 This is a side sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, with the air guide cover open and the air outlet pointing forward and upward. Figure 6 This is a side sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, with the air guide cover closed when the outdoor air vent is in place. Figures 4 to 6 As shown, optionally, when the outlet vent 212 is opened, the air guide cover 310 is configured to be located on one side of the main body of the outlet airflow discharged from the outlet vent 212 and configured to guide the main body of the outlet airflow.

[0056] This design allows the air guide cover 310 to control the direction of the airflow, so that when the air conditioner is in heating mode, the hot air blown out is directed downwards, and when it is in cooling mode, the cold air is directed forwards or upwards, thereby improving the temperature uniformity of the indoor environment.

[0057] Specifically, in this embodiment, when the air conditioner is in heating mode, the air guide cover 310 is lower at the front and higher at the back, with an angle of 30° to 60° with the vertical plane, so as to facilitate the hot air blown out by the wall-mounted air conditioner indoor unit to quickly reach the lower areas of the room. When the air conditioner is in cooling mode, the air guide cover 310 is higher at the front and lower at the back or remains horizontal, with an angle of 30° to 90° with the vertical plane, so as to facilitate the cold air blown out by the wall-mounted air conditioner indoor unit to blow towards the higher positions of the room and diffuse to a greater distance.

[0058] The term "guiding the main body of the airflow" refers to the fact that even when the outlet vent 212 is open and the rear edge of the guide cover 310 overlaps with the front wall of the outlet cavity 200, it cannot be guaranteed that the airflow from the air conditioner will be completely guided by the guide cover 310. A portion of the airflow will still be discharged upwards or downwards from between the rear edge of the guide cover 310 and the front wall of the outlet cavity 200. Furthermore, in this embodiment, when the outlet vent 212 is opened and the guide cover 310 is used to guide the main body of the airflow, there will still be a gap between the rear edge of the guide cover 310 and the front wall. Therefore, after the airflow exits from the outlet vent 212, a small portion will escape through this gap without being guided. Of course, the guide cover 310 can guide the main body of the airflow not only in a fixed state but also by swinging back and forth in the vertical plane to achieve alternating and reciprocating coverage of a large angle range by the wall-mounted air conditioner indoor unit.

[0059] Of course, in the implementation where the air outlet cavity 200 is located below the heat exchange cavity 110, if the air conditioner is in heating mode, the air guide cover 310 can be directly in a vertical position so that the hot air blown out by the indoor unit of the wall-mounted air conditioner blows directly downwards. If the air conditioner is in cooling mode, the angle between the air guide cover 310 and the horizontal plane can be less than or equal to 20° or less than or equal to 30° so that the blown cold air blows forward as much as possible.

[0060] Figure 7 This is a side sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model when the air guide cover is opened and the air is vented forward and downward. The section is located at the telescopic component. Figure 8 This is a side sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model when the air guide cover is opened and the air is vented forward and upward. The section is located at the telescopic component. Figure 9 This is a side sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, with the air outlet opened on the air guide cover and air flowing forward and downward. The section is located at the telescopic component. Figures 3 to 9 As shown, optionally, the air outlet opening and closing module 300 includes a telescopic mechanism 320 and a rotating mechanism 330. The rotating mechanism 330 is connected to the air guide cover 310 and is installed at the power output end of the telescopic mechanism 320. The telescopic mechanism 320 is used to drive the rotating mechanism 330 to approach and move away from the heat exchange chamber 110.

[0061] By setting up the telescopic mechanism 320 and the rotating mechanism 330 to drive the air guide cover 310, the air guide cover 310 can be pushed outward to the outlet air vent 212. The normal direction of the air guide cover 310 is located on both sides of the normal direction of the outlet air vent 212. This not only allows the hot air from the indoor unit of the wall-mounted air conditioner to blow downward, but also allows the cold air to blow forward and downward. This improves the air conditioner's ability to control the air outlet direction in different modes, thereby improving the uniformity of indoor space temperature during cooling or heating and enhancing the user experience.

[0062] In this embodiment, an air outlet cavity is provided so that the airflow passing through the inner air outlet 151 can diffuse within the air outlet cavity and then achieve zero-wind airflow through the air diffuser 210's diffuser holes 211 of the air outlet cavity body 200. Therefore, an air outlet duct like that of a traditional wall-mounted air conditioner indoor unit is not provided in the air outlet cavity, and there is no guiding effect of the traditional air outlet duct in the upstream adjacent area of ​​the air outlet. Therefore, a guide cover 310 is used to guide the main body of the airflow on one side, rather than the guide cover 310 being located in the middle of the width direction of the air outlet to guide the airflow. Therefore, taking the air outlet located at the front of the heat exchange chamber 110 as an example, when heating is required, i.e., when front-down air outlet is required, the rear edge of the air guide cover 310 is closer to the upper edge of the air outlet 212, while when front-up air outlet is required, the rear edge of the air guide cover 310 is closer to the lower edge of the air outlet 212. Furthermore, in zero-wind mode, the air guide cover 310 needs to cover the air outlet 212. Therefore, if the air guide cover 310 is directly pivotally connected to a fixed component, it is difficult to meet the above functions. This application uses a telescopic mechanism 320 to drive a rotating mechanism 330 to move closer to and further away from the heat exchange chamber 110. That is, when the air outlet 212 is opened, at least a portion of the rotating mechanism 330 extends out of the air outlet 212, providing sufficient space for the air guide cover 310 to swing, thus meeting the needs of cooling or heating.

[0063] It should be noted that the normal direction of the air guide cover 310 refers to the direction perpendicular to the surface of the air guide cover 310. Specifically, in this embodiment, the normal direction of the air guide cover 310 is in... Figure 4 The center is facing downwards to the right. Figure 5 The center faces upward to the right. The normal direction of the air outlet is... Figure 4 and Figure 5 From center to right, the normal direction of the air guide cover 310 is located on both sides of the normal direction of the outlet air vent 212.

[0064] Figure 10 This is a top sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model when the air guide cover closes the outside air vent. Figure 11This is a three-dimensional sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model when the air guide cover closes the outdoor air vent. Figure 3 and Figures 7 to 11 As shown, optionally, the telescopic mechanism 320 includes a telescopic member 321 and a telescopic drive assembly. The telescopic drive assembly is connected to the telescopic member 321 and is used to drive the telescopic member 321 in directions away from and towards the heat exchange chamber 110. The telescopic member 321 is equipped with a rotating mechanism 330.

[0065] By setting the telescopic component 321 to drive the rotating mechanism 330 to extend and retract, the number of components in the air outlet cavity can be reduced and the complexity of the shape can be reduced, thereby weakening the interference of the part of the telescopic mechanism 320 set in the air outlet cavity on the airflow.

[0066] In this embodiment, the telescopic drive assembly includes a telescopic drive motor 322, which is installed in the heat exchange chamber 110. A telescopic drive gear 323 is fixedly mounted on the power output end of the telescopic drive motor 322. In this embodiment, the telescopic component 321 can be a telescopic rod. A rack portion can be provided on the rear part of one side surface of the telescopic rod, such as the rear part of the lower surface of the telescopic rod. The telescopic drive gear 323 meshes with the rack portion to convert the rotation output by the telescopic drive motor 322 into the translation of the telescopic rod. In this embodiment, a guide groove 324 can be provided in the heat exchange chamber 110. The groove wall of the guide groove 324 mates with the surface of the telescopic rod to guide the movement of the telescopic rod. In this embodiment, the guide groove 324 extends in the front-back direction, so the telescopic rod moves in the front-back direction. It should also be noted that the telescopic component 321 does not refer to the component itself being able to extend or shorten. In this application, the telescopic member 321 refers to a component that can extend from the guide groove 324, with its length extending out of the guide groove 324 potentially increasing, and can retract into the guide groove 324, with its length extending out of the guide groove 324 potentially decreasing. In this embodiment, the rotating mechanism 330 is mounted on the front end of the telescopic rod.

[0067] like Figure 3 and Figures 7 to 11 As shown, optionally, the rotating mechanism 330 includes a rotating drive 331 and a rotating swing arm 332. The rotating swing arm 332 is fixedly connected to the air guide cover 310. The rotating drive 331 is connected to the rotating swing arm 332 and is used to drive the rotating swing arm 332 to rotate outside the air outlet 212.

[0068] By setting a rotating swing arm 332 that is fixedly connected to the air guide cover 310, the rotation axis of the air guide cover 310 can be separated from the air guide cover 310, thereby increasing the range of motion that the air guide cover 310 can move when swinging. This makes it easier for the air guide cover 310 to move to the position that guides the main body of the airflow, so that hot air can be blown downward as much as possible and cold air can be blown forward as much as possible, thereby improving the temperature uniformity of the indoor space.

[0069] In this embodiment, the rotary drive component 331 can be a guide vane drive motor, which is installed in a housing 325. The housing 325 can be integrally formed with the telescopic component 321. The housing 325 reduces the interference to airflow caused by the irregular surface shape of the guide vane drive motor. The power output shaft of the guide vane drive motor can be fixedly mounted on the rotary swing arm 332, for example, by using a flat shaft and a hole.

[0070] like Figure 1 and Figures 3 to 9 As shown, optionally, the outlet vent 212 is located in the middle of the diffuser plate 210 in the width direction.

[0071] Typically, the internal air outlet 151 is located in the middle of the width of the air outlet cavity. When the indoor unit of the wall-mounted air conditioner is in direct blowing mode, the external air outlet 212 can be directly opposite the internal air outlet 151, so that the airflow entering the air outlet cavity from the internal air outlet can reach the external air outlet 212 through the shortest path, reducing the loss of airflow in the air outlet cavity in the direct blowing mode and increasing the air volume.

[0072] Specifically, in this embodiment, since the indoor heat exchanger 130 installed in the heat exchange cavity 110 is a V-shaped heat exchanger with an opening facing forward, and the main unit casing 100 has air inlets 120 at both the top and bottom, the air conditioning fan 140 is centrally arranged in the heat exchange cavity 110 in the height direction, that is, the internal air outlet 151 is centrally located in the height direction of the partition plate 150. The front panel of the wall-mounted air conditioner indoor unit, i.e., the diffuser plate 210 of this application, typically has its length in the left-right direction, and its width in the up-down direction, i.e., the height direction. If the outlet 212 is located in the middle of the width direction of the diffuser plate 210, i.e., the middle of the front surface of the wall-mounted air conditioner indoor unit, it can correspond to the internal air outlet 151.

[0073] Of course, in another implementation, if the air outlet is located at the bottom of the heat exchange chamber 110, the width direction of the diffuser plate 210 is the front-to-back direction. Since the air conditioning fan 140 is also in the middle of the front-to-back direction in the heat exchange chamber 110, setting the outlet air vent 212 in the middle of the diffuser plate 210 in the front-to-back direction, that is, in the middle of the width direction, will make the outlet air vent 212 directly face the inner air supply vent 151.

[0074] like Figure 3 , Figure 10 and Figure 11 As shown, optionally, multiple air conditioning fans 140 are provided in the heat exchange chamber 110 along the left and right directions, and the internal air outlets 151 are provided in a one-to-one correspondence with the air conditioning fans 140. The length range of the external air outlets 212 is greater than or equal to the distribution range of the internal air outlets 151.

[0075] By setting the length range of the outgoing air vent 212 to be greater than or equal to the distribution range of the internal air supply vent 151, the air supplied from the internal air supply vent 151 to the air outlet cavity can be discharged from the outgoing air vent 212 through the shortest path, thereby reducing the loss of airflow in the air outlet cavity and increasing the air volume.

[0076] In this embodiment, two air conditioning fans 140 can be arranged side by side with intervals, and the rotation axis of the air conditioning fan 140 is perpendicular to the middle partition 150, that is, the rotation axis of the air conditioning fan 140 is in the front-back direction.

[0077] It should be noted that the length range of the outlet air vent 212 is greater than or equal to the distribution range of the inner air vents 151. This means that the length of the outlet air vent 212 is greater than or equal to the sum of the length of the solid part of the partition 150 between the multiple inner air vents 151 and the dimensions of the multiple inner air vents 151 in the left-right direction of the wall-mounted air conditioner indoor unit. In addition, the length of the outlet air vent 212 must cover the sum of the dimensions of the multiple inner air vents 151 and the length of the solid part of the partition 150 between adjacent inner air vents 151. That is, when the outlet air vent 212 is projected onto the partition 150, the length of the inner air vents 151 in the left-right direction and the length of the solid part between adjacent inner air vents 151 all fall within this projection. Taking an internal air outlet 151 as a circle with a diameter of 100mm and a solid portion of a partition 150 between two adjacent internal air outlets 151 of 300mm as an example, the length of the external air outlet 212 is at least 500mm. When this at least 500mm is projected onto the partition 150, the 100mm of the internal air outlet 151 and the 300mm interval are both within this at least 500mm range.

[0078] like Figure 3 , Figure 10 and Figure 11 As shown, optionally, when the outlet air vent 212 is closed, the side of the air guide cover 310 facing the inward air outlet 151 is provided with left and right sweeping blades 340.

[0079] This setting allows the air outlet to swing left and right in direct-blowing mode, or to change the direction of the air outlet within the left and right range, so as to deliver air to a wider area of ​​the indoor space, improve temperature uniformity, and enhance the user experience.

[0080] Specifically, when the outlet air vent 212 is closed, the side of the air guide cover 310 facing the inward air outlet 151 is the inner side of the air guide cover 310. In other words, this side is also the side where the main body of the outlet airflow is located when the air guide cover 310 guides the main body of the outlet airflow. Placing the left and right sweeping blades 340 here can affect the angle of the main body of the outlet airflow in the left and right directions.

[0081] In this embodiment, the left and right sweeping blades 340 can be driven by a motor driving a swing arm that drives a connecting rod, or the motor drives one left and right sweeping blade 340, which in turn drives the other left and right sweeping blades 340 to swing via a connecting rod. Alternatively, the position of the left and right sweeping blades 340 can be adjusted manually. How the left and right sweeping blades 340 perform left and right sweeping is a well-known technique in the art and will not be described in detail in this application.

[0082] Optionally, the left and right walls of the air outlet cavity 200 are arc-shaped sidewalls, which extend along an arc around the inner air outlet 151.

[0083] This configuration allows the distance between the air diffuser holes 211 at the left and right edges of the air diffuser plate 210 of the air outlet cavity 200 and the inner air outlet 151 to be similar, thereby achieving uniform airflow from the air diffuser holes 211 at multiple circumferential positions relative to the inner air outlet 151, improving the uniformity of airflow from the air diffuser holes 211 and making more effective use of the air diffuser holes 211 for airflow to improve the overall airflow volume.

[0084] Specifically, in this embodiment, the air diffuser 210 can be shaped like a track and field track, or a waist-shaped hole. The arc-shaped portions at its left and right ends correspond to the left and right side walls of the air outlet cavity 200, and the center of the arc can be the center of the air outlet.

[0086] Embodiment 2 also provides an air conditioner, including a wall-mounted indoor unit and an outdoor unit of any of the above-mentioned types, wherein the outdoor unit is connected to the wall-mounted indoor unit via a refrigerant connection pipe.

[0087] By installing the aforementioned wall-mounted air conditioner indoor unit in the air conditioner, the air conditioner accordingly possesses all the advantages of the aforementioned wall-mounted air conditioner indoor unit, which will not be elaborated upon here.
