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 existing wall-mounted air conditioner indoor units in zero-wind mode.

[0006] The first aspect of this utility model provides a wall-mounted air conditioner indoor unit, including a main unit housing and an air outlet duct. A fan cavity is formed inside the main unit housing, and an air outlet cavity is formed inside the air outlet duct. The fan cavity is connected to the air outlet cavity through an inner air outlet. The air outlet duct includes an inner air outlet duct and an outer air outlet duct. The peripheral wall of the inner air outlet duct is provided with a plurality of first air diffusers penetrating along the thickness direction, and the outer air outlet duct is provided with a plurality of second air diffusers penetrating along the thickness direction. The inner air outlet duct can be switched between a first position and a second position relative to the outer air outlet duct. In the first position, the first air diffusers and the second air diffusers are at least partially corresponding. In the second position, the first air diffusers and the second air diffusers are completely misaligned.

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

[0008] By incorporating an internal air outlet duct within the fan cavity that can move relative to the external air outlet duct, the relative positional relationship between the first and second air diffusers can be altered. In the first position, the airflow from the fan cavity enters through the internal air outlet and is then discharged from the wall-mounted air conditioner indoor unit through at least a portion of the corresponding first and second air diffusers, thus cooling or heating the environment. Simultaneously, the airflow is dispersed by the first and second air diffusers, causing it to merge with the ambient air shortly after exiting the wall-mounted air conditioner indoor unit, providing users with a feeling of no or zero wind while simultaneously achieving cooling or heating. The inclusion of the air outlet duct allows for the placement of air diffusers over a larger area, resulting in a greater airflow volume while maintaining the density, size, and other conditions of the diffusers, thereby improving the speed of temperature regulation.

[0009] In an optional technical solution, the wall-mounted air conditioner indoor unit includes an inner cylinder drive mechanism, which is connected to the inner air outlet duct. The inner air outlet duct is an arc-shaped cylinder, and the inner circumferential surface of the outer air outlet duct is a cylindrical surface. The inner air outlet duct and the outer air outlet duct are rotatably connected relative to each other.

[0010] The inner air outlet duct is rotatably connected to the outer air outlet duct, and the inner duct drive mechanism is driven to rotate the inner air outlet duct relative to the outer air outlet duct. Even if a part of the inner air outlet duct is deformed, the friction of movement will not be significantly increased, thus ensuring that the inner air outlet duct can move smoothly relative to the outer air outlet duct and switch between the first and second positions of the inner air outlet duct, so as to determine whether the indoor unit of the wall-mounted air conditioner vents air through the first and second air outlets.

[0011] In an optional technical solution, the inner air outlet duct is fixedly connected to an inner cylinder drive rod extending circumferentially along the air outlet cavity. The circumferential surface of the inner cylinder drive rod is provided with a first arc-shaped rack. The inner cylinder drive mechanism includes an inner cylinder drive motor. The inner cylinder drive motor is fixedly arranged relative to the outer air outlet duct. The inner cylinder drive motor is connected to the inner cylinder drive rod through the meshing of the inner cylinder drive gear and the first arc-shaped rack.

[0012] The inner cylinder drive motor drives the inner air outlet duct to rotate by meshing the inner cylinder transmission gear with the first arc-shaped rack set on the inner cylinder transmission rod. This can directly convert the force of the inner cylinder transmission gear into the torque that drives the inner air outlet duct to rotate, without significantly increasing the pressure and friction between the inner air outlet duct and the outer air outlet duct, so as to control the torque output required by the motor.

[0013] In an optional technical solution, both ends of the inner cylinder drive rod are fixedly connected to the inner air outlet duct, and the outer circumferential surface of the inner cylinder drive rod is rotatably connected to the inner circumferential surface of the outer air outlet duct.

[0014] This design allows for support at both ends of the inner cylinder drive rod, improving its rigidity. Furthermore, the connection between the inner outlet duct and the inner cylinder drive rod, along with the outer circumference of the inner cylinder drive rod, forms a complete annular surface that fits against the inner circumference of the outer outlet duct, thus supporting the relative rotation of the inner and outer outlet ducts.

[0015] In an optional technical solution, the wall-mounted air conditioner indoor unit further includes an air outlet opening and closing mechanism, which includes an air outlet cover. The air outlet cover is movably disposed relative to the outdoor air duct. The air outlet cover can switch between a third position and a fourth position relative to the outdoor air duct. In the third position, the air outlet cover can open the outdoor air outlet located at the end of the outdoor air duct. In the fourth position, the air outlet cover closes the end of the outdoor air duct and closes the outdoor air outlet.

[0016] By setting an air outlet opening and closing mechanism, the following can be achieved: when the air outlet cover is in the third position, the air outlet at the end of the external air duct is opened, which can guide the airflow to be discharged from the air outlet. This is to match the situation where the first and second air diffusers are completely misaligned when the internal air outlet is in the second position, and the airflow cannot be discharged from the second air diffuser. When the air outlet cover is in the fourth position, the air outlet is closed, so that the first and second air diffusers are at least partially aligned when the internal air outlet is in the first position, and the airflow can be discharged from the second air diffuser.

[0017] In an optional technical solution, the air outlet opening and closing mechanism further includes an end cover deflection assembly. The end cover deflection assembly includes a deflection drive motor, a deflection output component, and a deflection transmission component. The deflection drive motor is fixedly disposed relative to the external air duct, and the deflection output component is rotatably disposed in the external air duct. The axis of rotation of the deflection output component relative to the external air duct is parallel to the length direction of the external air duct. The deflection drive motor is connected to the deflection output component through the deflection transmission component, and the air outlet cover is movably mounted on the deflection output component.

[0018] By setting a deflection drive motor to rotate the deflection output component along an axis parallel to the length of the outlet air duct via a deflection transmission component, the position of the rotation axis when the air outlet cover opens the outlet air vent can be changed. This alters the direction in which the air outlet cover guides the airflow out of the outlet air vent, facilitating adjustments to the airflow direction in different air conditioning modes. For example, in heating mode, the position of the air outlet cover connected to the deflection output component is adjusted to the upper part, causing the air outlet cover to lift upwards to open the outlet air vent. The airflow is then guided downwards by the air outlet cover, allowing hot air to reach the ground as much as possible and improving indoor temperature uniformity. In cooling mode, the position of the air outlet cover connected to the deflection output component is adjusted to the rear, causing the air outlet cover to lift backwards to open the outlet air vent. The airflow is then guided forwards by the air outlet cover, allowing cold air to blow forward as much as possible and improving indoor temperature uniformity.

[0019] In an optional technical solution, the deflection output component is provided with a second arc-shaped rack, the second arc-shaped rack being located on the inner circumferential surface of the deflection output component, and the deflection transmission component includes an end cover deflection gear fixedly connected to the power output end of the deflection drive motor, the end cover deflection gear meshing with the second arc-shaped rack.

[0020] By setting the second arc-shaped rack on the inner circumference of the deflection output component, and by using the end cover deflection gear to mesh with the second arc-shaped rack, the force of the end cover deflection gear can be directly converted into the torque to drive the deflection output component without significantly increasing the pressure and friction between the deflection output component and the external air duct. This allows the deflection drive motor to drive the end cover deflection gear to rotate with a smaller torque.

[0021] In an optional technical solution, the air outlet cover is pivotally connected to the deflection output component, and the air outlet cover is fixedly connected to the transmission part; the air outlet opening and closing mechanism includes an end cover opening and closing motor fixedly installed on the deflection output component, and the end cover opening and closing motor is drivingly connected to the transmission part.

[0022] By setting a transmission part to fix the air outlet cover, when the air outlet cover is subjected to airflow that opens the air vent or causes the air vent to open more widely, the distance between the position of the transmission part and the pivot axis of the air outlet cover increases. This increases the torque of the force that hinders the opening of the air outlet cover from being applied to both the transmission part and the air outlet cover, which helps to balance the airflow force and makes it easier to control the position of the air outlet cover.

[0023] In an optional technical solution, the air outlet cover includes a cover body and a guide rib fixedly connected to the cover body. When the air outlet cover is in the fourth position, the guide rib is located on the surface of the air outlet cover facing the inside of the external air duct. When the air outlet cover is in the third position, the guide rib extends in a direction away from the external air duct.

[0024] By setting up air guide ribs, the airflow can be guided after it encounters the cover of the air outlet, allowing it to flow along the air guide ribs, thereby improving the directionality of the airflow and facilitating cooling or heating of the corresponding area in the indoor space.

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

[0026] The air conditioner provided in the second aspect of this utility model includes an outdoor unit and a wall-mounted indoor unit, wherein the wall-mounted indoor unit is connected to the outdoor 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

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 structural schematic diagram of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, viewed from another direction. Figure 4 The image shows a right view of the indoor unit of a wall-mounted air conditioner provided in Embodiment 1 of this utility model. 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 inner air outlet duct in the second position. Figures 1 to 6 As shown, the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model includes a main unit housing 100 and an air outlet duct. A fan cavity 110 is formed inside the main unit housing 100, and an air outlet cavity is formed inside the air outlet duct. The fan cavity 110 is connected to the air outlet cavity through an inner air outlet 151. The air outlet duct includes an inner air outlet duct 200 and an outer air outlet duct 300. The peripheral wall of the inner air outlet duct 200 is provided with a plurality of first air diffusers 210 penetrating along the thickness direction, and the outer air outlet duct 300 is provided with a plurality of second air diffusers 310 penetrating along the thickness direction. The inner air outlet duct 200 can switch between a first position and a second position relative to the outer air outlet duct 300. In the first position, the first air diffusers 210 and the second air diffusers 310 are at least partially corresponding. In the second position, the first air diffusers 210 and the second air diffusers 310 are completely misaligned.

[0058] By providing an inner air outlet duct 200 that can move relative to the outer air outlet duct 300 within the fan cavity 110, the relative positional relationship between the first air diffuser 210 and the second air diffuser 310 can be changed. In the first position, the air from the fan cavity 110 enters the fan cavity 110 through the inner air outlet 151 and is then discharged from the wall-mounted air conditioner indoor unit through at least partially corresponding first and second air diffusers 210 and 310, providing cooling or heating to the environment. Simultaneously, due to the dispersing effect of the first and second air diffusers 210 and 310, the airflow merges with the ambient air shortly after exiting the wall-mounted air conditioner indoor unit, allowing users to experience a windless or zero-wind sensation while simultaneously providing cooling or heating. Because of the air outlet duct, air diffusers can be installed over a larger area, thereby achieving a larger airflow while keeping the density, size, and other conditions of the air diffusers constant, thus improving the speed of temperature regulation.

[0059] 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 typically 5 to 8 centimeters, rarely exceeding 10 centimeters. Therefore, the area where the ventilation holes can be installed in a traditional wall-mounted air conditioner indoor unit is the width multiplied by the length of the air outlet. However, this application, by placing the first ventilation hole 210 and the second ventilation hole 310 on the inner air outlet duct 200 and the outer air outlet duct 300, allows the width of the ventilation hole area to be 30 centimeters or even 50 centimeters. The length of the ventilation hole area can be comparable to, or even approximately equal to, the length of the air outlet of a traditional wall-mounted air conditioner indoor unit. This significantly increases the area where the ventilation holes can be installed. Naturally, with the distribution density, size, and other conditions of the ventilation holes remaining unchanged, a larger air volume can be obtained.

[0060] In addition, when the inner air outlet duct 200 is in the second position, the solid part of the inner air outlet duct 200 blocks the second air vent 310, making it difficult for outside air to enter the air outlet cavity. This also reduces the possibility of dust in the air entering the air outlet cavity when the indoor unit of the wall-mounted air conditioner is not blowing air, preventing dust from accumulating on the first air vent 210 or the inner wall of the air outlet cavity, which would cause the air conditioner to blow out dust when it is used again.

[0061] Specifically, in this embodiment, the air outlet is located in front of the main unit housing 100, that is, the fan cavity 110 is located behind the air outlet cavity. The fan cavity 110 is separated from the air outlet cavity by a partition plate 150 at the front of the fan cavity 110. The main unit housing 100 has an upper air inlet 121 at the top and a lower air inlet 122 at the bottom. An indoor heat exchanger 130 is located inside the main unit housing 100, i.e., in the fan cavity; specifically, the longitudinal section of the indoor heat exchanger 130 can be approximately a U-shape with an opening facing forward. Air entering the fan cavity 110 from the upper air inlet 121 and the lower air inlet 122, after heat exchange with the indoor heat exchanger 130, can be drawn in by the fan 140. In this embodiment, the fan 140 is located at the front of the fan cavity 110 and installed on the partition plate 150. The type of fan 140 can be an axial flow fan, a mixed flow fan, or a vortex fan, and the axis of these fans 140 is arranged along the front-to-back direction. In this embodiment, the two fans 140 of the above type can be arranged in a left-right direction, and the inner air outlet 151 on the partition 150 is correspondingly provided with the fans 140, and its shape can be circular. Of course, in another implementation, the fans 140 can also be cross-flow fans, with the axis of the cross-flow fan in the left-right direction, and the inner air outlet 151 on the partition 150 can be rectangular or rounded rectangle, the length of which is similar to the length of the impeller of the cross-flow fan.

[0062] In this embodiment, the end of the external air duct 300 is cylindrical, while in a larger area along its length, the middle section of the external air duct 300, where it connects to the main housing 100, is semi-cylindrical. Since the air outlet cavity is located in front of the fan cavity 110 in this embodiment, a second air diffuser 310 is provided at the front of the external air duct 300. In this embodiment, the second air diffuser 310 penetrates the peripheral wall of the external air duct 300 along its thickness direction, preferably with the extension direction of the second air diffuser 310 aligned with the thickness direction of the peripheral wall of the external air duct 300. Similarly, the first air diffuser 210 penetrates the peripheral wall of the inner air outlet duct 200 along its thickness direction, preferably with the extension direction of the first air diffuser 210 aligned with the thickness direction of the peripheral wall of the inner air outlet duct 200. Of course, in other implementations, the extension directions of the first air diffuser 210 and the second air diffuser 310 can be set at an angle to the thickness direction of the corresponding peripheral wall.

[0063] In this embodiment, both the first air diffuser 210 and the second air diffuser 310 are circular. Of course, in other implementations, the first air diffuser 210 and the second air diffuser 310 can be other shapes, such as rectangles, rhombuses, or rounded rectangles or rounded rhombuses. The second air diffusers 310 can be arranged in columns, with each column of second air diffusers 310 projected horizontally into an adjacent column. More specifically, the second air diffusers 310 can be located at the midpoint between two adjacent second air diffusers 310. Furthermore, if the external air duct 300 is unfolded along its circumference, three adjacent second air diffusers 310 can be arranged in an equilateral triangle. The arrangement of the first air diffuser 210 is the same as that of the second air diffuser 310, and will not be described again.

[0064] It should be noted that the first air diffuser 210 and the second air diffuser 310 in this application correspond at least partially, including both complete and partial correspondence. When the inner air outlet duct 200 is in the first position, the first air diffuser 210 and the second air diffuser 310 correspond completely, that is, if the first air diffuser 210 and the second air diffuser 310 are not the same size, the smaller one falls entirely within the range of the other. If the first air diffuser 210 and the second air diffuser 310 are the same size, then they overlap. Of course, in another implementation, when the inner air outlet duct 200 is in the first position, the first air diffuser 210 and the second air diffuser 310 can correspond partially to form an air diffusion channel from the inside of the air outlet duct to the outside.

[0065] Unless otherwise specified, this embodiment describes the air outlet duct as being located at the front of the main unit housing 100. However, in another implementation, the air outlet duct can also be located below the main unit housing 100, in which case an inner air outlet 151 is provided at the lower part of the main unit housing 100 to connect to the air outlet cavity. In this implementation, an air inlet 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 fan 140. After air enters from the air inlet on the top or upper front surface of the main unit housing 100, it exchanges heat with the indoor heat exchanger 130 in the fan cavity 110 and is then drawn by the fan 140 into the air outlet cavity through the inner air inlet. If the air conditioner is in cooling mode, when the first air vent 210 of the inner air duct 200 and the second air vent 310 of the outer air duct 300 are aligned, the cold air is discharged from the air outlet in a zero-air mode. Since the area of ​​the air outlet duct is large and the number of air outlets is large, a large air volume is generated to meet the cooling needs.

Figure 8This is a top sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model when the inner air outlet is in the second position. Figure 9 This is a schematic diagram of the structure of the inner air outlet duct and the inner cylinder transmission rod in the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model. Figure 10 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 cutting plane located on the inner cylinder transmission rod. Figures 5 to 10 As shown, optionally, the wall-mounted air conditioner indoor unit includes an inner cylinder drive mechanism 400, which is connected to the inner air outlet duct 200. The inner air outlet duct 200 is an arc-shaped cylinder, and the inner circumferential surface of the outer air outlet duct 300 is a cylindrical surface. The inner air outlet duct 200 and the outer air outlet duct 300 are rotatably connected relative to each other.

[0067] The inner air outlet duct 200 is rotatably connected to the outer air outlet duct 300. The inner duct drive mechanism 400 is driven to rotate the inner air outlet duct 200 relative to the outer air outlet duct 300. Even if some areas of the inner air outlet duct 200 are deformed, the friction of movement will not be significantly increased. This ensures that the inner air outlet duct 200 can move smoothly relative to the outer air outlet duct 300 and switch between the first and second positions of the inner air outlet duct 200 to determine whether the indoor unit of the wall-mounted air conditioner vents air through the first air vent 210 and the second air vent 310.

[0068] Specifically, in this embodiment, an inner cylinder driving mechanism 400 is respectively provided at both ends of the air outlet cavity, thereby applying a force to the inner air outlet duct 200 from both ends of its length direction, causing it to rotate relative to the outer air outlet duct 300. Since the inner air outlet duct 200 is relatively long, and there is friction between the inner air outlet duct 200 and the outer air outlet duct 300, if the inner air outlet duct 200 is driven only at the left end, the rotation angle of the right end of the inner air outlet duct 200 may differ significantly from that of the directly driven left end, or even not rotate at all, resulting in the first air diffuser 210 and the second air diffuser 310 not corresponding. Driving the inner air outlet duct 200 from both ends of its length direction can reduce or even eliminate the difference in rotation angle at different length positions of the inner air outlet duct 200, thereby achieving accurate control of the positions of the first air diffuser 210 and the second air diffuser 310. In this embodiment, the central angle of the inner air outlet duct 200 relative to its rotation axis can be 180°.

[0069] Of course, in another implementation, the internal air outlet duct 200 can be slidably connected to the external air outlet duct 300, and the sliding direction can be the length direction of the air outlet duct, specifically the left and right direction. When the first air vent 210 on the internal air outlet duct 200 and the second air vent 310 on the external air outlet duct 300 adopt the above-mentioned shape and arrangement, the internal air outlet duct 200 can slide left and right relative to the external air outlet duct 300, which can also realize the switching of the internal air outlet duct 200 between the first position and the second position to control whether the indoor unit of the wall-mounted air conditioner is venting air in zero-wind mode.

[0070] like Figures 7 to 10 As shown, optionally, the inner air outlet duct 200 is fixedly connected to an inner cylinder drive rod 410 extending circumferentially along the air outlet cavity. The inner cylinder drive rod 410 has a first arc-shaped rack 411 on its circumferential surface. The inner cylinder drive mechanism 400 includes an inner cylinder drive motor 420. The inner cylinder drive motor 420 is fixedly arranged relative to the outer air outlet duct 300. The inner cylinder drive motor 420 is connected to the inner cylinder drive rod 410 through the meshing of the inner cylinder drive gear 430 and the first arc-shaped rack 411.

[0071] The inner cylinder drive motor 420 drives the inner air outlet duct 200 to rotate by meshing the inner cylinder transmission gear 430 with the first arc-shaped rack 411 set on the inner cylinder transmission rod 410. This can directly convert the force of the inner cylinder transmission gear 430 into the torque that drives the inner air outlet duct 200 to rotate, without significantly increasing the pressure and friction between the inner air outlet duct 200 and the outer air outlet duct 300, so as to control the torque output required by the motor.

[0072] In this embodiment, an inner cylinder drive gear 430 can be fixedly connected to the output shaft of the inner cylinder drive motor 420. A first arc-shaped rack 411 is provided on the inner circumferential surface of the first arc-shaped rack 411, which is connected to the inner cylinder drive gear 430. In this embodiment, the inner cylinder drive rod 410 is an arc-shaped rod. The center of the first arc-shaped rack 411 is the rotation axis of the inner air outlet duct 200. Since switching the inner air outlet duct 200 between the first and second positions does not require a large movement distance—for example, in this embodiment, the movement distance is even less than the distance between two adjacent first air diffusers 210 in the same column—the length of the toothed portion of the first arc-shaped rack 411 does not need to be large, and it does not need to be machined on the inner circumferential surface along the entire length of the inner cylinder connecting rod. This design reduces the machining difficulty of the inner cylinder drive rod 410.

[0073] In this embodiment, the inner cylinder drive motor 420 can be located at the front or middle of the outer side of both ends of the main housing 100 along its length. Since the main housing 100 is fixed relative to the outer ventilation duct 300, the inner cylinder drive motor 420 is fixedly positioned relative to the outer ventilation duct 300. This arrangement reduces the space occupied by the inner cylinder drive motor 420 in the outer ventilation duct 300 along its length. Since the fan 140 is an axial flow fan, vortex fan, or mixed flow fan, although the inner cylinder drive motor 420 is located at the end of the main housing 100 and occupies some internal space, it does not significantly affect the air intake of the fan 140. Alternatively, in another implementation, the inner cylinder drive motor 420 can also be located on the outer ventilation duct 300.

[0074] like Figure 9 As shown, optionally, both ends of the inner cylinder drive rod 410 are fixedly connected to the inner air outlet duct 200, and the outer circumferential surface of the inner cylinder drive rod 410 is rotatably connected to the inner circumferential surface of the outer air outlet duct 300.

[0075] This configuration allows for support at both ends of the inner cylinder drive rod 410, improving its rigidity. Furthermore, the portion of the inner outlet duct 200 that connects to the inner cylinder drive rod 410 and the outer circumferential surface of the inner cylinder drive rod 410 can form a complete annular circumferential surface, which fits against the inner circumferential surface of the outer outlet duct 300, thus supporting the relative rotation of the inner outlet duct 200 and the outer outlet duct 300.

[0076] Of course, in another implementation, the inner cylinder drive rod 410 can be fixedly connected to the inner air outlet duct 200 at only one end, which can still satisfy the basic function of driving the inner air outlet duct 200 to rotate relative to the outer air outlet duct 300. Of course, if it is not necessary to support the inner air outlet duct 200 through contact between the inner cylinder drive rod 410 and the outer air outlet duct 300, for example, if the central angle of the inner air outlet duct 200 with respect to its axis is greater than 180°, then the inner air outlet duct 200 can be positioned relative to the outer air outlet duct 300, and the outer circumferential surface of the inner cylinder drive rod 410 can be separated from the inner circumferential surface of the outer air outlet duct 300.

[0077] Figure 11 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 cover is in the third position. Figure 12 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 cover is in the third position. Figure 13 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 cover is in the third position and both the air outlet cover and the deflection output component are separated from the outside air duct. Figure 14This is a top-view perspective sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, with the air outlet cover in the third position. The cut surface is higher than the deflection drive motor. Figure 7 , Figure 8 and Figures 11 to 14 As shown, optionally, the wall-mounted air conditioner indoor unit also includes an air outlet opening and closing mechanism 500, which includes an air outlet cover 510. The air outlet cover 510 is movably disposed relative to the outdoor air duct 300. The air outlet cover 510 can switch between a third position and a fourth position relative to the outdoor air duct 300. In the third position, the air outlet cover 510 can open the outdoor air outlet located at the end of the outdoor air duct 300. In the fourth position, the air outlet cover 510 closes the end of the outdoor air duct 300 and closes the outdoor air outlet.

[0078] By setting the air outlet opening and closing mechanism 500, the following can be achieved: when the air outlet cover 510 is in the third position, the air outlet at the end of the external air duct 300 is opened, and the airflow is guided out of the air outlet to cooperate with the complete misalignment of the first air diffuser 210 and the second air diffuser 310 when the internal air outlet duct 200 is in the second position, so that the airflow cannot be discharged from the second air diffuser 310; and when the air outlet cover 510 is in the fourth position, the air outlet is closed, so that the first air diffuser 210 and the second air diffuser 310 are at least partially corresponding when the internal air outlet duct 200 is in the first position, and the airflow can be discharged from the second air diffuser 310.

[0079] In this embodiment, an air outlet opening and closing mechanism is provided at each end of the external air outlet of the external air duct 300 to control the opening or closing of the external air outlet. Of course, in another implementation, one air outlet opening and closing mechanism 500 can be set to control two air outlet covers 510.

[0080] In another implementation, with two air outlet opening and closing mechanisms 500 and two fans 140 arranged left and right, a partition can be installed in the middle of the left and right sides of the air outlet cavity to divide it into a left air outlet cavity and a right air outlet cavity where airflow does not interfere with each other. The number of inner air outlet ducts 200 can also be two, allowing for individual control of the position of each inner air outlet duct 200. This allows the left and right air outlet ducts of a wall-mounted air conditioner indoor unit to output air in different modes. For example, in the left air outlet cavity, the air outlet cover 510 is in the third position, the outflow vent of the left air outlet cavity is open, and the inner air outlet duct 200 on the left side moves to the second position. The first diffuser 210 and the second diffuser 310 are completely misaligned. Therefore, the airflow entering the left air outlet cavity cannot be discharged from the second diffuser 310 and can only be discharged from the outflow vent at the left end of the air outlet cavity, i.e., the airflow in the left air outlet cavity is in a direct blowing manner. In the right air outlet chamber, the air outlet cover 510 is in the fourth position, the outflow vent of the right air outlet chamber is closed, and the inner air outlet duct 200 on the right side moves to the first position, with the first diffuser hole 210 and the second diffuser hole 310 at least partially corresponding. Therefore, the airflow entering the right air outlet chamber can be discharged through the second diffuser hole 310 but cannot be discharged through the air outlet at the right end of the air outlet chamber. That is, the air is discharged in the form of diffused air in the right air outlet chamber. Thus, different forms of air discharge are achieved in different air outlet chambers.

[0081] Of course, in another implementation, if the inner air outlet duct 200 is slidably installed in the outer air outlet duct 300, then the aforementioned air outlet opening and closing mechanism can be installed to control the position of the air outlet cover 510. Alternatively, it may not be necessary to install a separate air outlet opening and closing mechanism to drive the movement of the air outlet cover 510. During normal operation of the air conditioner, because the first air vent 210 and the second air vent 310 are completely misaligned and open with the air outlet cover 510, the two can be linked. When the indoor unit of the wall-mounted air conditioner discharges air, it discharges either from the second air vent 310 or from the outer air outlet. Therefore, the linkage between the inner air outlet duct 200 and the air outlet cover 510 can be used to drive the air outlet cover 510 to open and close relative to the outer air outlet duct 300. For example, the air outlet cover 510 can be rotatably set with the outer air duct 300, and a connecting rod is set to be pivotally connected to the inner air outlet duct 200 and the air outlet cover 510 respectively. Then, the inner air outlet duct 200, the connecting rod, the air outlet cover 510 and the outer air duct 300 form a single-degree-of-freedom crank-slider mechanism. The sliding position of the inner air outlet duct 200 relative to the outer air duct 300 can directly correspond to the opening degree of the air outlet cover 510 relative to the outer air duct 300.

[0082] Figure 15 This is a top-view perspective sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model when the air outlet cover is in the third position, viewed from another direction. The sectional plane is higher than the deflection drive motor. Figure 16This is a schematic diagram of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, viewed from another direction with the air outlet cover in the third position and both the air outlet cover and the deflection output component separated from the outdoor air duct. Figure 7 , Figure 8 and Figures 11 to 16 As shown, optionally, the air outlet opening and closing mechanism 500 further includes an end cover deflection assembly 520. The end cover deflection assembly 520 includes a deflection drive motor 521, a deflection output component 522, and a deflection transmission component 523. The deflection drive motor 521 is fixedly disposed relative to the outdoor air duct 300. The deflection output component 522 is rotatably disposed in the outdoor air duct 300. The axis of rotation of the deflection output component 522 relative to the outdoor air duct 300 is parallel to the length direction of the outdoor air duct 300. The deflection drive motor 521 is connected to the deflection output component 522 through the deflection transmission component 523. The air outlet cover 510 is movably disposed relative to the deflection output component 522 and rotates relative to it, with the axis of rotation perpendicular to the length direction of the outdoor air duct 300.

[0083] By setting the deflection drive motor 521 to drive the deflection output component 522 to rotate along an axis parallel to the length of the outlet air duct 300 via the deflection transmission component 523, the position of the rotation axis of the air outlet cover 510 when the outlet air vent is opened can be changed. This changes the guiding direction of the airflow discharged from the outlet air vent by the air outlet cover 510 when it is open, which is beneficial for adjusting the airflow direction in different air conditioning modes. For example, when the air conditioner is in heating mode, the position of the air outlet cover 510 connected to the deflection output component 522 is adjusted to the upper part, and the air outlet cover 510 is lifted from bottom to top to open the outlet air vent. Therefore, the airflow can be guided downward by the air outlet cover 510 so that the hot air can reach the ground as much as possible, improving the uniformity of indoor temperature. If the air conditioner is in cooling mode, rotate the air outlet cover 510 to adjust the position of the deflection output component 522 to the rear. The air outlet cover 510 is lifted from front to back to open the air outlet. Therefore, the airflow can be guided forward by the air outlet cover 510 so that the cold air can be blown forward as much as possible to improve the uniformity of indoor temperature.

[0084] In this embodiment, the deflection output component 522 is generally annular. At least a portion of the outer peripheral surface of the deflection output component 522 contacts the outlet air duct 300 to radially position the deflection output component 522. The deflection output component 522 is rotatably disposed at the end of the inner outlet air duct 200. In this embodiment, the rotation angle range of the deflection output component 522 relative to the outlet air duct 300 is at least 90°, and further, it can be an angle greater than 90°, such as 110° or 120°. Since the position of the deflection output component 522 rotatably connected to the air outlet cover 510 is at the rear or lower part of the two ends of the air outlet cavity, the deflection drive motor 521 can be disposed at the upper or front part of the end region of the outlet air duct 300. In addition, since the inner outlet air duct 200 is provided with an inner cylinder drive rod 410, to avoid interference, the deflection drive motor 521 is located between the end face of the inner outlet air duct 200 and the outlet air vent.

[0085] like Figure 7 , Figure 8 and Figures 11 to 16 As shown, optionally, the deflection output member 522 is provided with a second arc-shaped rack 524, the second arc-shaped rack 524 is located on the inner circumferential surface of the deflection output member 522, and the deflection transmission member 523 includes an end cover deflection gear fixedly connected to the power output end of the deflection drive motor 521, the end cover deflection gear meshing with the second arc-shaped rack 524.

[0086] By setting the second arc-shaped rack 524 on the inner circumferential surface of the deflection output component 522, and by using the end cover deflection gear to mesh with the second arc-shaped rack 524, the force of the end cover deflection gear can be directly converted into the torque to drive the deflection output component 522 without significantly increasing the pressure and friction between the deflection output component 522 and the external air duct 300. Thus, the deflection drive motor 521 can drive the end cover deflection gear to rotate with a smaller torque.

[0087] In this embodiment, the second arc-shaped rack 524 is an arc-shaped toothed portion disposed within a portion of the circumferential range of the deflection output member 522. The angular range of the second arc-shaped rack 524 distributed on the inner circumferential surface of the deflection output member 522 should be greater than the rotation angle range of the deflection output member 522 relative to the external air duct 300. For example, if the deflection output member 522 rotates 90° relative to the external air duct 300, the distribution range of the second arc-shaped rack 524 on the inner circumferential surface of the deflection output member 522 can be greater than 100°.

[0088] Figure 17 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, in which the air outlet cover and the deflection output component are in a separated state. Figure 18 This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, with the air outlet cover and the deflection output component separated, viewed from another direction. Figure 19This is a schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, with the air outlet cover and the deflection output component separated, viewed from another direction. Figure 7 , Figure 8 and Figures 11 to 19 As shown, optionally, the air outlet cover 510 is pivotally connected to the deflection output member 522, and the air outlet cover 510 is fixedly connected to the transmission part 513; the air outlet opening and closing mechanism 500 includes an end cover opening and closing motor 531 fixedly installed on the deflection output member 522, and the end cover opening and closing motor 531 is connected to the transmission part 513 in a transmission connection.

[0089] By providing a transmission part 513 to fixally connect the air outlet cover 510, when the air outlet cover 510 is subjected to airflow that opens the air outlet or causes the air outlet to open more widely, the distance between the position of the transmission part 513 subjected to the force and the pivot axis of the air outlet cover 510 increases. This increases the torque of the force that hinders the opening of the air outlet cover 510, thereby balancing the airflow force and facilitating the control of the position of the air outlet cover 510.

[0090] In this embodiment, the transmission unit 513 may include an arc-shaped plate portion 514 or an arc-shaped ring fixedly connected to the air outlet cover 510. The inner circumferential surface of the arc-shaped plate portion 514 or the arc-shaped ring is provided with a third arc-shaped rack 515. The central angle corresponding to the third arc-shaped rack 515 relative to the rotation axis of the air outlet cover 510 is greater than or equal to the opening angle of the air outlet cover 510. Of course, to improve the connection rigidity of the arc-shaped plate portion 514 or the arc-shaped ring, a connecting rib 516 may also be provided on the end face of the arc-shaped plate portion 514 or the arc-shaped ring. The power output end of the end cover opening / closing motor 531 is fixedly connected to an end cover opening / closing gear 532, which meshes with the third arc-shaped rack 515. Furthermore, when the air outlet cover 510 is in the fourth position, the end cover opening / closing gear 532 and the end cover opening / closing motor 531 may be located within the space enclosed by the transmission unit 513, the air outlet cover 510, and the deflection output member 522. That is, the transmission part 513 can form a flow guide shroud, at least partially covering the area where the end cover opening and closing motor 531, the end cover opening and closing gear 532, the pivot shaft 525, and the pivot hole 517 are located. When the air outlet cover 510 is in the third position, the airflow does not pass through these parts, which can significantly reduce the airflow passing through these parts, thereby reducing the interference of the above-mentioned structures on the airflow and improving the airflow efficiency. It should be noted that since the air outlet cover 510 is in the third position, it is usually not completely perpendicular to the air outlet, because if it is completely perpendicular, the guiding effect of the air outlet cover 510 on the airflow is significantly reduced. For example, an angle of 45° or 60° can effectively open the air outlet. Therefore, although there is a distance between the edge of the free end of the arc plate part 514 and the corresponding area of ​​the inner circumference of the deflection output member 522, the flow guide shroud formed can still block the end cover opening and closing motor 531 and other components to a considerable extent, reducing the interference of these components on the airflow.

[0091] In addition, the transmission part 513 is provided with a pivot hole 517, which is rotatably connected to the pivot shaft 525 provided on the deflection output part 522.

[0092] Of course, in another implementation, the end cover opening and closing motor 531 can also drive the air outlet cover 510 to rotate through a four-bar linkage mechanism.

[0093] like Figure 11 , Figure 12 and Figures 14 to 19 As shown, optionally, the air outlet cover 510 includes a cover body 511 and an air guide rib 512 fixedly connected to the cover body 511. When the air outlet cover 510 is in the fourth position, the air guide rib 512 is located on the surface of the air outlet cover 510 facing the inside of the outgoing air duct 300; when the air outlet cover 510 is in the third position, the air guide rib 512 extends in a direction away from the outgoing air duct 300.

[0094] By setting the air guide rib 512, the airflow can be guided after it encounters the cover body 511 of the air outlet cover 510, so that the airflow flows along the air guide rib 512, thereby improving the directionality of the airflow and facilitating cooling or heating of the corresponding part of the indoor space.

[0095] Specifically, in this embodiment, multiple air guide ribs 512 can be provided on an air outlet cover 510, and the multiple air guide ribs 512 are arranged in parallel. If the position of the air outlet cover 510 connected to the deflection output component 522 is located at the rear, the air guide ribs 512 can extend in the horizontal direction. That is, in the case where multiple air guide ribs 512 are parallel, the extension direction of the air guide ribs 512 is perpendicular to the rotation axis of the air outlet cover 510. Of course, since the wind speed is higher in the area closer to the axis of the air outlet cavity, the height of the air guide rib 512 located in the middle of the multiple air guide ribs 512 arranged side by side on the air outlet cover 510 is higher than the other air guide ribs 512, or the length of the area where the height of the middle air guide rib 512 is higher is greater than the length of the other air guide ribs 512.
