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, a front housing, an air conditioning fan, and an air outlet opening / closing module. The front housing is disposed on the front side of the main unit housing and has multiple air dissipation holes extending along the wall thickness direction. The top of the front housing has an upper air outlet. A partition is provided inside the main unit housing, forming an air outlet cavity between the partition and the front housing, and forming a heat exchange cavity between the partition and the bottom of the main unit housing. When the air conditioning fan is running, the air outlet cavity and the heat exchange cavity are connected. The air outlet opening / closing module includes an air guide cover for opening and closing the upper air outlet, and the air guide cover is movably disposed relative to the front housing.

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

[0008] By setting multiple air diffusers on the front casing, which is significantly larger than the air outlet area of ​​a traditional wall-mounted air conditioner indoor unit, a larger area can be covered for these diffusers. With the density and size of the diffusers remaining constant, and other conditions unchanged, a larger airflow can be achieved in zero-wind mode, improving the speed of temperature regulation. Furthermore, the air outlet opening / closing module allows the upper air outlet to be opened, enabling the airflow entering the air chamber to be directly discharged from the upper air outlet in direct-blow mode. This achieves greater airflow for regulating the indoor temperature in direct-blow mode.

[0009] In an optional technical solution, the air outlet cavity includes an upper air outlet cavity and a lower air outlet cavity. The upper air outlet cavity is located between the upper air outlet and the partition, and the lower air outlet cavity is located between the front shell and the partition. A movable guide plate is also provided inside the air outlet cavity. The movable guide plate is movably disposed relative to the main housing. The movable guide plate is configured to move between a first position and a second position. When the movable guide plate is in the first position, it connects the outlet end of the air conditioning fan and the lower air outlet cavity. When the movable guide plate is in the second position, it blocks the air conditioning fan and the lower air outlet cavity.

[0010] A movable baffle is installed in the air outlet cavity. When direct airflow is needed, the movable baffle is in its second position to block the air conditioner fan and the lower air outlet cavity, thereby significantly reducing the proportion of airflow from the air conditioner fan exiting through the diffuser holes on the front casing. Furthermore, the upper surface of the movable baffle can guide the airflow from the air conditioner fan in this position. When the movable baffle is in its first position, the air outlet opening and closing module closes the upper air outlet, while the movable baffle connects the air conditioner fan's outlet end and the lower air outlet cavity. The airflow from the air conditioner fan can then flow into the lower air outlet cavity and exit through the diffuser holes on the front casing. This allows for the use of more diffuser holes in zero-wind mode, increasing the airflow volume in zero-wind mode.

[0011] In an optional technical solution, when the movable guide plate is in the first position, the rear end of the movable guide plate is connected to the air conditioner fan.

[0012] With this configuration, when the movable guide plate is in the first position, the gap between the rear end of the movable guide plate and the outlet of the air conditioner fan is reduced, so that after the air is guided by the movable guide plate, it can flow into the area of ​​the front wall panel of the front shell in the downward air outlet cavity, so as to facilitate the rapid discharge of airflow from the diffuser hole.

[0013] In an optional technical solution, a guide plate is provided on the upper side of the air outlet cavity, the front end of the guide plate is connected to the front shell, and the rear end of the guide plate is connected to the partition; along the direction from back to front, the angle between the guide plate and the front-back direction gradually decreases.

[0014] By setting up such a deflector plate, the airflow can be gradually guided after the air conditioner fan discharges its air out of its outlet. The direction of the inlet end of the deflector plate is close to the air outlet direction of the air conditioner fan, while the airflow direction of the outlet end of the deflector plate is closer to the front-to-back direction. This gradually turns the airflow direction toward the upper air outlet, thereby reducing the resistance when the airflow turns and reducing the loss of airflow energy.

[0015] In an optional technical solution, when the upper air outlet is opened, the air guide cover is configured to be located on one side of the main body of the airflow discharged from the upper air outlet and to guide the main body of the airflow.

[0016] 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.

[0017] 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 retract into the air outlet cavity and at least partially extend out of the upper air outlet.

[0018] By setting up telescopic and rotating mechanisms to drive the air guide cover, the air guide cover can be pushed outward to the external air outlet. The normal direction of the air guide cover is located on both sides of the normal direction of the upper air outlet. 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.

[0019] 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.

[0020] 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.

[0021] 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 upper air outlet.

[0022] 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.

[0023] In an optional technical solution, the air guide cover is provided with the air dissipation hole that extends through the plate thickness direction.

[0024] This design increases the size of the ventilation opening area, making full use of the front surface area of ​​the front cover to increase the number of ventilation openings and improve airflow.

[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

[0047] Example 1:

[0048] Figure 1 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 upper air outlet is closed. 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 when the air outlet is directed forward and upward. 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, viewed from another direction when the upper air outlet is closed. Figure 4 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 when the air outlet is blowing air forward and upward. Figures 1-4 As shown, the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model includes a main unit housing 100, a front housing 200, an air conditioning fan 140, and an air outlet opening / closing module 300. The front housing 200 is located on the front side of the main unit housing 100 and has multiple air vents 210 extending along the wall thickness direction. The top of the front housing 200 has an upper air outlet 220. A partition 150 is provided inside the main unit housing 100, forming an air outlet cavity between the partition 150 and the front housing 200, and a heat exchange cavity 110 is formed between the partition 150 and the bottom of the main unit housing 100. When the air conditioning fan 140 is running, the air outlet cavity and the heat exchange cavity 110 are connected. The air outlet opening / closing module 300 includes a guide cover 310 for opening and closing the upper air outlet 220, and the guide cover 310 is movably disposed relative to the front housing 200.

[0049] By setting multiple air diffusers 210 on the front casing 200, which is significantly larger than the air outlet area of ​​a traditional wall-mounted air conditioner indoor unit, a larger area can be provided for the air diffusers 210. With the density, size, and other conditions of the air diffusers 210 remaining unchanged, a larger air volume can be obtained in zero-wind mode, improving the speed of temperature regulation. Furthermore, the air outlet opening / closing module 300 is provided to open the upper air outlet 220, allowing the airflow entering the air outlet cavity to be directly discharged from the upper air outlet 220 in direct-blow mode. This achieves temperature regulation of the indoor environment with a larger air volume in direct-blow mode.

[0050] 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 diffuser 210 can be set in a traditional wall-mounted air conditioner indoor unit is equal to this width multiplied by the length of the air outlet. Because 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. Therefore, the length of the air outlet of a traditional wall-mounted air conditioner indoor unit is difficult to be almost equal to the length of the wall-mounted air conditioner indoor unit. However, by setting the diffuser 210 on the front shell 200, the diffuser 210 can be distributed in the area of ​​the front shell 200 excluding the upper air outlet 220. Therefore, the width of the area where the diffuser 210 is set can be about 30 centimeters. Moreover, because a separate air outlet cavity is set, the length of the front shell 200 can be almost equal to the length of the wall-mounted air conditioner indoor unit. With the distribution density, size and other conditions of the air diffuser 210 remaining unchanged, a larger air volume can be obtained.

[0051] In this embodiment, the air outlet cavity is located in front of and above the heat exchange cavity 110, that is, the heat exchange cavity 110 is located behind and below the air outlet cavity. The heat exchange cavity 110 is separated from the air outlet cavity by a partition plate 150 at the front and top of the heat exchange cavity 110. The bottom of the main unit housing 100 is provided with an air inlet 120, and an indoor heat exchanger 130 is provided inside the main unit housing 100, i.e., in the heat exchange cavity 110. In this embodiment, the indoor heat exchanger 130 can maintain a front-high, rear-low orientation. The 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. In this embodiment, the air conditioning fan 140 is located at the top of the heat exchange cavity 110 and installed on the partition plate 150. The type of air conditioning fan 140 can be an axial flow fan, a mixed flow fan, or a vortex fan, and the axis of these fans is arranged along the front-to-back direction. In this embodiment, the two air conditioning fans 140 of the above type can be arranged in a left-right direction. The upper part of the air conditioning fan 140 extends into the air outlet cavity, thereby making full use of the height of the air outlet cavity to reduce the overall height of the wall-mounted air conditioner indoor unit. Of course, in another implementation, the fan can also be a cross-flow fan with the axis of the cross-flow fan in the left-right direction, and the air outlet on the partition 150 can be a rectangle or a rounded rectangle, the length of which is similar to the length of the impeller of the cross-flow fan.

[0052] In this embodiment, all ventilation holes 210 are circular. Of course, in other implementations, the ventilation holes 210 can be other shapes, such as rectangles, rhombuses, or rounded rectangles or rounded rhombuses. The ventilation holes 210 can be arranged in columns, with each column of ventilation holes 210 projected horizontally into an adjacent column. More specifically, the ventilation holes 210 can be located at the midpoint between two adjacent ventilation holes 210. Furthermore, three adjacent ventilation holes 210 can be arranged in an equilateral triangle.

[0053] Furthermore, it should be noted that when the air guide cover 310 opens the corresponding air outlet, although the air outlet cavity is provided with diffuser holes 210, and the airflow may be discharged from the diffuser holes 210, the resistance of the upper air outlet 220 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 210. Therefore, the airflow is mainly or almost entirely discharged from the air outlet cavity through the upper air outlet 220, and only a very small amount of airflow is discharged from the diffuser holes 210 of the diffuser plate.

[0054] Figure 6 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 outlet is discharging air forward and downward from the top, viewed from another direction. 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 upper air outlet is closed. Figure 8This 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 pointing forward and downward. 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 pointing forward and upward. Figure 4 and Figures 6 to 9 As shown, optionally, the air outlet cavity includes an upper air outlet cavity and a lower air outlet cavity. The upper air outlet cavity is located between the upper air outlet 220 and the partition 150, and the lower air outlet cavity is located between the front shell 200 and the partition 150. A movable guide plate 410 is also provided in the air outlet cavity. The movable guide plate 410 is movably arranged relative to the main unit shell 100. The movable guide plate 410 is configured to move between a first position and a second position. When the movable guide plate 410 is in the first position, it connects the outlet end of the air conditioning fan 140 and the lower air outlet cavity. When the movable guide plate 410 is in the second position, it blocks the air conditioning fan 140 and the lower air outlet cavity.

[0055] A movable guide vane 410 is installed in the air outlet cavity. When direct airflow is required, the movable guide vane 410 is in a second position to block the air conditioner fan 140 and the lower air outlet cavity, thereby significantly reducing the proportion of air from the air conditioner fan 140 exiting through the diffuser holes 210 of the front housing 200. Moreover, the upper surface of the movable guide vane 410 can also guide the airflow from the air conditioner fan 140 at this time. When the movable guide vane 410 is in the first position, the air outlet opening and closing module 300 closes the upper air outlet 220, while the movable guide vane 410 connects the outlet end of the air conditioner fan 140 and the lower air outlet cavity. The air from the air conditioner fan 140 can flow into the lower air outlet cavity and exit through the diffuser holes 210 of the front housing 200, realizing the use of more diffuser holes 210 for airflow in zero-wind mode, thus increasing the airflow volume in zero-wind mode.

[0056] Specifically, in this embodiment, the partition 150 includes a vertical portion 151 at the front and a horizontal portion 152 at the rear, which are connected by an arc-shaped transition portion 153. The lower air outlet cavity is mainly formed by the vertical portion 151 of the partition 150 and the front shell 200. The upper air outlet cavity is mainly formed by the horizontal portion 152 of the partition 150, the upper air outlet 220, and the guide plate 160 described later.

[0057] A guide vane rotary motor 420 is installed in the air outlet cavity, and a movable guide vane 410 is fixedly connected to a first swing arm. Furthermore, the movable guide vane 410 and the first swing arm are integrally formed and connected, wherein the first swing arm can be approximately triangular. The power output shaft of the guide vane rotary motor 420 is fixedly mounted with the first swing arm. When the movable guide vane 410 is in the second position, the front end of the movable guide vane 410 overlaps the lower edge of the upper air outlet 220, and the rear end of the movable guide vane 410 overlaps the transition portion 153 of the partition 150, thereby separating the upper air outlet cavity and the lower air outlet cavity to block the air conditioning fan 140 and the lower air outlet cavity.

[0058] like Figure 7 As shown, optionally, when the movable guide plate 410 is in the first position, the rear end of the movable guide plate 410 is connected to the air conditioner fan 140.

[0059] With this configuration, when the movable guide plate 410 is in the first position, the gap between the rear end of the movable guide plate 410 and the outlet of the air conditioning fan 140 is reduced, so that after the air is guided by the movable guide plate 410, it can flow in the area of ​​the front wall panel of the front shell 200 in the downward air outlet cavity, so as to facilitate the rapid discharge of airflow from the diffuser hole 210.

[0060] Specifically, in this embodiment, when the movable guide plate 410 is in the first position, the rotation axis of the movable guide plate 410 is located below its front part, and the movable guide plate 410 is in a posture with the front lower than the rear. When the movable guide plate 410 is in the second position, the rotation axis is located above its rear part, and the movable guide plate 410 is in a posture with the front higher than the rear.

[0061] Figure 10 This is a schematic diagram of the internal structure of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of the present invention, after omitting some components of the front shell and the air outlet opening and closing module. Figure 11 This is a three-dimensional sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, with the air outlet pointing forward and upward. Figures 6 to 11 As shown, optionally, a guide plate 160 is provided on the upper side of the air outlet cavity. The front end of the guide plate 160 is connected to the front shell 200, and the rear end of the guide plate 160 is connected to the partition plate 150. Along the direction from back to front, the angle between the guide plate 160 and the front-back direction gradually decreases.

[0062] By setting up such a deflector plate 160, the airflow can be gradually guided after the air conditioner fan 140 discharges air to its outlet. The direction of the inlet end of the deflector plate 160 is close to the air outlet direction of the air conditioner fan 140, while the airflow direction at the outlet end of the deflector plate 160 is closer to the front-back direction. This gradually turns the airflow direction toward the upper air outlet 220, thereby reducing the resistance when the airflow turns and reducing the loss of airflow energy.

[0063] In this embodiment, the flow guide plate 160 can be an upward extension of the rear wall of the heat exchange chamber 110. The rear wall of the heat exchange chamber 110 is inclined from bottom to top and forward. Therefore, the angle of the rear end of the flow guide plate 160, i.e. the inlet end of the flow guide plate 160, is not vertically upward.

[0064] Figure 5 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, where the air outlet is directed downwards and forwards. Figure 5 , Figure 6 and Figure 8, Figure 9 As shown, optionally, when the upper air outlet 220 is open, the air guide cover 310 is configured to be located on one side of the main body of the airflow discharged from the upper air outlet 220 and configured to guide the main body of the airflow.

[0065] 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.

[0066] 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.

[0067] The term "guiding the main body of the airflow" refers to the fact that even when the rear edge of the air guide cover 310 overlaps with the front wall of the air outlet cavity when the upper air outlet 220 is open, it cannot be completely guaranteed that the airflow from the air conditioner will be completely guided by the air guide cover 310. A portion of the airflow will be discharged upwards or downwards from between the rear edge of the air guide cover 310 and the front wall of the air outlet cavity. Moreover, in this embodiment, when the upper air outlet 220 is opened and the air 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 air guide cover 310 and the front wall. Therefore, after the airflow is discharged from the upper air outlet 220, a small portion will be discharged through this gap without being guided. Of course, the air 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, so as to achieve alternating and reciprocating coverage of a large angle range by the indoor unit of the wall-mounted air conditioner.

[0068] Of course, in the implementation where the air outlet cavity 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.

[0069] like Figure 4 , Figure 6 , Figure 10 and Figure 11As 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 retract into the air outlet cavity and at least partially extend out of the upper air outlet 220.

[0070] By setting 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 external air outlet. The normal direction of the air guide cover 310 is located on both sides of the normal direction of the upper air outlet 220. This not only allows the hot air to blow downward when the indoor unit of the wall-mounted air conditioner is discharging hot air, but also allows the cold air to blow forward and downward when discharging cold air. 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.

[0071] In this embodiment, the air guide cover 310 is positioned on one side of the main body of the outlet airflow to guide the main body of the outlet airflow, rather than the air guide cover 310 being positioned in the middle of the outlet airflow in the width direction of the outlet. Therefore, taking the outlet cavity located at the front of the heat exchange cavity 110 as an example, when heating is required, i.e., when front-downward airflow is required, the rear edge of the air guide cover 310 is closer to the upper edge of the upper outlet 220, while when front-upward airflow is required, the rear edge of the air guide cover 310 is closer to the lower edge of the upper outlet 220. Moreover, in zero-wind mode, the air guide cover 310 needs to cover the upper outlet 220. Therefore, if the air guide cover 310 is directly pivotally connected to a fixed component, it is difficult to meet the above functions. In this application, the telescopic mechanism 320 drives the rotating mechanism 330 to retract into the air outlet cavity and at least partially extend out of the upper air outlet 220. That is, when the upper air outlet 220 is opened, at least part of the rotating mechanism 330 extends out of the upper air outlet 220, providing sufficient space for the air guide cover 310 to swing to meet the needs of cooling or heating.

[0072] 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 8 The center is facing downwards to the right. Figure 9 The center faces upward to the right. The normal direction of the air outlet is... Figure 8 and Figure 9 From center to right, the normal direction of the air guide cover 310 is located on both sides of the normal direction of the upper air outlet 220.

[0073] like Figure 4 , Figure 6 , Figure 10 and Figure 11As 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.

[0074] 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.

[0075] In this embodiment, the telescopic drive assembly includes a telescopic drive motor 322, which is installed on the left and right sides of the upper air outlet cavity. A telescopic drive gear 323 is fixedly installed 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 one side surface of the telescopic rod, such as the upper 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, guide grooves 324 can be provided on the left and right outer surfaces of the upper air outlet cavity. The groove walls of the guide grooves 324 cooperate with the surface of the telescopic rod to guide the movement of the telescopic rod. In this embodiment, the guide grooves 324 extend 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, telescopic member 321 refers to a component that can extend out of guide groove 324, with its length extending out of guide groove 324 potentially increasing, and can retract into guide groove 324, with its length extending out of guide groove 324 potentially decreasing. In this embodiment, rotating mechanism 330 is installed at the front end of telescopic rod.

[0076] like Figure 4 , Figure 6 , Figure 9 and Figure 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 upper air outlet 220.

[0077] 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.

[0078] 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.

[0079] like Figures 1 to 9 and Figure 11 As shown, optionally, the air guide cover 310 is provided with a diffuser hole 210 that extends through the plate thickness direction.

[0080] This configuration increases the size of the area where the air diffuser 210 is located, thereby making full use of the front surface area of ​​the front cover 200 to increase the number of air diffusers 210 and improve the air volume.

[0081] The air vents 210 on the air guide cover 310 can have the same distribution density, vent size and distribution shape as other areas of the front shell 200 to achieve a consistent visual appearance on the front surface of the wall-mounted air conditioner indoor unit.

[0082] like Figures 7 to 9 and Figure 11 As shown, optionally, an indoor heat exchanger 130 is provided in the heat exchange chamber 110, the front of the indoor heat exchanger 130 is higher than the rear, and a water receiving tray is provided on the rear wall plate of the heat exchange chamber 110, with the rear of the heat exchanger located above the water receiving tray.

[0083] This configuration not only increases the width of the indoor heat exchanger 130 to improve its heat exchange capacity, but also allows the water tray to support part of the weight of the indoor heat exchanger 130, and allows the condensate from the indoor heat exchanger 130 to flow into the water tray and finally be discharged from the interior of the wall-mounted air conditioner indoor unit through the drain pipe 180.

[0084] Specifically, in this embodiment, a protruding ridge is provided in the upper part of the front wall of the heat exchange chamber 110 to support the front of the indoor heat exchanger 130, while the rear end of the heat exchanger is supported in the water receiving tray. The angle between the width direction of the heat exchanger and the horizontal plane can be from 10° to 40°.
