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] Generally, the air outlets of wall-mounted air conditioner indoor units provide relatively uniform airflow along their length. However, it is difficult to achieve situations where significant differences in airflow are needed between different parts of the unit along its length, such as significant differences in the vertical angle and / or airflow speed. For example, it is difficult to achieve a situation where the airflow from the left half of the air conditioner is directed downwards and stronger, while the airflow from the right half is directed forwards and weaker. Utility Model Content

[0003] The first objective of this utility model is to provide a wall-mounted air conditioner indoor unit to solve the technical problem that existing systems cannot adapt to the requirements of different air outlet directions in different locations.

[0004] The first aspect of this utility model provides a wall-mounted air conditioner indoor unit, including a base, on which a fan assembly is installed. A portion of the base forms a flow guide cavity, and the flow guide cavity has a partition in the middle of its left-right direction. The flow guide cavity is divided into two sub-flow guide cavities—a left flow guide cavity and a right flow guide cavity—by the partition. Each of the left and right flow guide cavities is provided with an independently movable air duct plate, which is used to adjust the airflow direction of the left and right flow guide cavities.

[0005] The beneficial effects of this wall-mounted air conditioner indoor unit are:

[0006] By dividing the airflow cavity into two sub-cavities—a left and a right—the partition allows for independent control of the airflow direction of each sub-cavity using independently moving air duct plates. This enables separate control of the airflow direction in each sub-cavity. Furthermore, the partition prevents the airflow from flowing in series between the two sub-cavities, ensuring that the airflow within the wall-mounted air conditioner's indoor unit remains uninterrupted.

[0007] In an optional technical solution, the sub-guide cavity includes a front air outlet duct and a fan air outlet duct. The front air outlet duct is connected to the front air outlet, and a lower air outlet is provided below the fan air outlet duct. The duct plate is used to control at least one of the front air outlet duct and the lower air outlet to be connected to the fan air outlet duct.

[0008] By controlling the air duct plate to connect at least one of the front air outlet and the lower air outlet to the fan outlet duct, it is possible to use the lower air outlet, the front air outlet, or both simultaneously for air delivery. This expands the air outlet area of ​​the air conditioner without excessively increasing the airflow velocity, which could lead to noise issues. Especially when the indoor unit of a wall-mounted air conditioner uses a diffuser plate with a dispersing function, increasing the outlet area allows for an increase in the area of ​​the diffuser plate and the number of dispersing holes, which helps improve the airflow in zero-wind mode.

[0009] In an optional technical solution, the front air outlet duct has a front air outlet, which is located at the front of the fan outlet duct, and the air duct plate is configured to switch between a first position that blocks the front air outlet and a second position that blocks the air outlet.

[0010] In an optional technical solution, the duct plate is rotatably arranged relative to the fan outlet duct, and the rotation axis of the duct plate is located at the lower part or below the front air duct inlet.

[0011] This design not only shortens the airflow path when the air passes through the front air outlet, reducing energy loss, but also allows for control of the airflow at the front air outlet and the lower air outlet using the duct plate. By reducing the total number of drive components for the duct plate, the manufacturing cost of the wall-mounted air conditioner indoor unit can be controlled.

[0012] In an optional technical solution, the duct plate includes a switching plate body. When the duct plate is in the second position, the upper surface of the switching plate body smoothly transitions with the front surface of the rear duct wall of the fan outlet duct.

[0013] This design allows the air duct plate to move by rotation, thereby reducing frictional resistance during movement. Furthermore, by positioning the air duct plate's axis of rotation at this location, simply rotating the plate is sufficient to block the lower air outlet and the front air duct inlet, improving operational efficiency.

[0014] In an optional technical solution, when the air duct plate is in the second position, the upper surface of the switching plate body smoothly transitions with the rear surface of the lower air duct wall of the front air outlet.

[0015] This configuration allows the airflow from the rear of the fan assembly to be guided by the rear duct wall of the fan outlet, and then further guided by the upper surface of the switching plate and blown into the front duct inlet. The continuous and stable flow of airflow, guided by the rear duct wall of the fan outlet and the switching plate, reduces the consumption of airflow inside the air conditioner, improves airflow efficiency, and reduces noise.

[0016] In an optional technical solution, each of the sub-guided cavities is independently provided with a fan outlet, and the fan assembly is independently provided above each fan outlet.

[0017] This configuration allows for continuous and stable airflow when the fan assembly's air is guided by the upper surface of the switching plate and enters the front air outlet duct. This reduces the consumption of airflow inside the air conditioner, improves airflow efficiency, and reduces noise.

[0018] In an optional technical solution, the fan assembly is arranged vertically, the fan assembly is a mixed-flow fan, and the rear duct wall of the fan outlet duct is provided with a first guide rib; the side of the duct plate facing the front outlet duct is provided with a second guide rib, and along the flow direction of the airflow from the fan assembly, at least a portion of the second guide rib gradually moves away from the axis of the fan assembly in the length direction of the wall-mounted air conditioner indoor unit, and at least a portion of the second guide rib is correspondingly arranged with the first guide rib.

[0019] By setting the first and second guide ribs, the air outlet at the rear of the fan assembly can be guided to deviate from the axis of the fan assembly and disperse along the left and right directions of the wall-mounted air conditioner indoor unit. This helps to make full use of the length of the wall-mounted air conditioner indoor unit and improve the uniformity of the air outlet along the length of the wall-mounted air conditioner indoor unit.

[0020] In an optional technical solution, a lower air outlet duct is connected to the lower part of the lower air outlet.

[0021] By installing a lower air outlet duct at the lower air outlet, the airflow leaving the lower air outlet can be guided. Moreover, the airflow in the air outlet duct does not come into contact with the air outside the indoor unit of the wall-mounted air conditioner. The length of the airflow with the pressure in the upstream direction being greater than the air pressure in the downstream direction is also increased, thereby increasing the airflow speed. This is especially beneficial for the hot air blown out by the air conditioner in heating mode to move downwards, thereby improving the temperature uniformity of the indoor space and enhancing the user experience.

[0022] The second objective of this utility model is to provide an air conditioner that can solve the technical problem of not being able to adapt to the requirements of different air outlet directions in different parts.

[0023] 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.

[0024] 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 wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, omitting the air outlet structure. Figure 3 for Figure 2 The diagram shown is a structural schematic of a wall-mounted air conditioner indoor unit with the second partition omitted. Figure 4 for Figure 3 Front view. Figure 5 This is a front sectional view of the indoor unit of the wall-mounted air conditioner provided in Embodiment 1 of this utility model, with the section cut at the fan assembly. Figure 6 for Figure 2 The diagram shown is a structural schematic of a wall-mounted air conditioner indoor unit, omitting the second partition and the air duct plate in the left guide cavity. Figure 7 This is a side sectional view of the indoor unit of a wall-mounted air conditioner provided in Embodiment 1 of this utility model, with the air duct plate located in the first position. (See image below.) Figures 1-7 As shown, the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model includes a base 100, a fan assembly 200 installed on the base 100, a guide cavity 110 partially formed in the base 100, a partition 150 provided in the middle of the guide cavity 110 in the left-right direction, the guide cavity 110 is divided into two sub-guide cavities by the partition 150 - a left guide cavity and a right guide cavity, and an independently movable air duct plate 300 is provided in the left guide cavity and the right guide cavity respectively, the air duct plate 300 is used to adjust the air direction of the left guide cavity and the right guide cavity.

[0045] By dividing the airflow cavity 110 into two sub-airflow cavities—a left airflow cavity and a right airflow cavity—with a partition 150, the airflow direction of each sub-airflow cavity can be controlled using an independently moving air duct plate 300 within each airflow cavity 110. This allows for separate control of the airflow direction of each sub-airflow cavity. Furthermore, the partition 150 prevents the airflow in the two sub-airflow cavities from being connected in series, ensuring that the airflow in the two sub-airflow cavities does not interfere with each other inside the wall-mounted air conditioner indoor unit.

[0046] Specifically, in this embodiment, an air inlet 121 is provided at the top of the wall-mounted air conditioner indoor unit, and a heat exchanger 122 is provided below the air inlet 121. The heat exchanger 122 can be an inverted V-shaped heat exchanger 122, and the lowest point of the inverted V-shaped heat exchanger 122 can be lower than the air inlet area of ​​the fan assembly 200. Air enters the interior of the wall-mounted air conditioner indoor unit through the air inlet 121, exchanges heat with the heat exchanger 122, and is then driven by the fan assembly 200 to be discharged from below the fan assembly 200 and flow into the fan outlet duct 111.

[0047] A first partition 131 can be installed on the base 100 to divide the space within the air duct into a fan chamber 120 and a guide chamber 110. The fan chamber 120 is located above the first partition 131, and the fan assembly 200 and heat exchanger 122 are disposed within the fan chamber 120. The guide chamber 110 is located below the first partition 131, and the fan outlet 111, air duct plate 300, and lower air outlet 112 are all located within the guide chamber 110. The front of the fan chamber 120 can be a second partition 132, which separates a front air outlet 140 located at the front and the fan chamber 120 located behind it. The front air outlet 141 can occupy more than two-thirds of the front surface area of ​​the wall-mounted air conditioner indoor unit, thereby increasing the air outlet area of ​​the wall-mounted air conditioner indoor unit. In addition, a grille can be provided at the front air outlet 141 to support the corresponding air outlet structure 160. Specifically, the air outlet structure 160 can be a diffuser with zero-wind-feel air outlet function, or a sweeping mechanism with upper and lower sweeping blades and / or left and right sweeping blades.

[0048] In this embodiment, the partition 150 can be a partition plate to divide the guide cavity 110 into a left guide cavity and a right guide cavity. Since there is no airflow movement inside the partition 150, using a partition plate as the partition 150 can increase the size of the left and right guide cavities, or in other words, it can minimize the size of the wall-mounted air conditioner indoor unit in the left-right direction while keeping the size of the left and right guide cavities unchanged, i.e., reduce the length of the wall-mounted air conditioner indoor unit. Of course, in another implementation, if the angle between the airflow from each sub-guide cavity and the left-right direction is too small, i.e., too inclined relative to the front-back direction, the partition 150 can be in the form of a partition block with spaced left and right sidewalls. This setting can increase the distance between the right end and the left end of the left guide cavity, thereby avoiding the airflow from the left and right guide cavities colliding as soon as it exits the air outlet of the wall-mounted air conditioner indoor unit.

[0049] Figure 8 This is a side sectional view of the indoor unit of the wall-mounted air conditioner provided in Embodiment 1 of this utility model, with the air duct plate located in the first position. 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 duct plate located between the first and second positions. Figures 2 to 9 As shown, optionally, the sub-guide cavity includes a front air outlet 140 and a fan air outlet 111. The front air outlet 140 is connected to the front air outlet 141, and a lower air outlet 112 is provided below the fan air outlet 111. The duct plate 300 is used to control at least one of the front air outlet 140 and the lower air outlet 112 to be connected to the fan air outlet 111.

[0050] By controlling the air duct plate 300 to connect at least one of the front air outlet 140 and the lower air outlet 112 to the fan outlet 111, air can be discharged using the lower air outlet 112, the front air outlet 140, or both simultaneously. This expands the air outlet area of ​​the air conditioner without excessively increasing the airflow velocity, which could lead to noise issues. Especially when the indoor unit of a wall-mounted air conditioner uses a diffuser plate with a diffuser function, increasing the outlet area allows for an increase in the area of ​​the diffuser plate and the number of diffuser holes, which helps to improve the airflow in zero-wind mode.

[0051] like Figures 2 to 9 As shown, optionally, the front air outlet duct 140 has a front air outlet duct 142, which is located at the front of the fan outlet duct 111. The air duct plate 300 is configured to switch between a first position blocking the front air outlet 142 and a second position blocking the air outlet 112. Figures 2 to 5 and Figure 8 The air duct panel 300 is shown in its second position. Figure 7 The air duct panel 300 is shown in its first position. Figure 6 and Figure 9 Displays the state between the first and second positions.

[0052] This design not only shortens the airflow path when the air passes through the front air outlet 140, reducing energy loss, but also allows for control of the airflow from the front air outlet 142 and the lower air outlet 112 using the air duct plate 300. By reducing the total number of drive components for the air duct plate 300, the manufacturing cost of the wall-mounted air conditioner indoor unit can be controlled.

[0053] Specifically, in this embodiment, the front air duct inlet 142 can extend along the length direction of the wall-mounted air conditioner indoor unit, i.e., the left-right direction, and its length can correspond to the overall length of the fan outlet duct 111 or the guide cavity 110. In this embodiment, the lower air outlet 112 can be a circular air outlet, corresponding to each fan assembly 200 in the left-right direction and the front-back direction of the wall-mounted air conditioner indoor unit. The lower opening of the fan outlet duct 111 is correspondingly set to the duct plate 300. When the duct plate 300 is in the second position, the duct plate 300 blocks the lower opening of the fan outlet duct 111, thereby also blocking the lower air outlet 112.

[0054] Of course, in addition to the first position and the second position, the air duct plate 300 can move between the first position and the second position. At this time, the airflow of the fan assembly 200 can achieve the following: part of the air is discharged through the front air outlet 141 via the front air outlet 140, while the other part is discharged through the lower air outlet 112 to achieve lower airflow.

[0055] like Figure 2 , Figure 3 and Figures 6 to 9 As shown, optionally, the air duct plate 300 is rotatably arranged relative to the fan outlet duct 111, and the rotation axis of the air duct plate 300 is located at the lower part or below the front air duct inlet 142.

[0056] This configuration allows the air duct plate 300 to move by rotation, thereby reducing the frictional resistance during its movement. Furthermore, by setting the rotation axis of the air duct plate 300 at this location, simply rotating the air duct plate 300 is sufficient to block the lower air outlet 112 and the front air duct inlet 142, thus improving movement efficiency.

[0057] Specifically, in this embodiment, the rotation axis of the duct plate 300 is located at the lower opening of the fan outlet duct 111, more specifically, at the front end of the lower opening, i.e., below the front air duct inlet 142. This allows the duct plate 300 to switch between a first position blocking the front air duct inlet 142 and a second position blocking the lower air outlet 112 by swinging. Of course, the duct plate 300 can rotate to an angle between the first and second positions. In this case, the airflow from the fan assembly 200 can be: partly flowing from the side of the duct plate 300 facing the front air outlet 140 and exiting through the front air outlet 141, and the other part flowing from the side of the duct plate 300 facing the lower air outlet 112 and exiting through the lower air outlet 112 to achieve downward airflow.

[0058] In another implementation, the movement of the duct plate 300 relative to the fan outlet 111 can also be achieved by sliding the duct plate 300 on a preset track. For example, an arc-shaped rack can be installed on the fan switching plate. The arc-shaped rack is circular, with the teeth facing the center of the arc. A motor drives the arc-shaped rack through the meshing of gears, thereby driving the duct plate 300 to move along the arc. The duct plate 300 can be slidably connected to the left and right side walls of the air conditioner, for example, through a sliding groove, or it can be connected through rollers. When the duct plate 300 moves to the front of the fan outlet 111, that is, when it moves to the first position, the duct plate 300 blocks the front air duct inlet 142 and exposes the lower air outlet, so that the airflow does not exit from the lower air outlet 112. When the duct plate 300 moves to below the fan outlet duct 111, i.e., to the second position, the duct plate 300 blocks the lower air outlet 112 and exposes the front air outlet 142, thus allowing air to exit from the front air outlet duct 140. Of course, the duct can be switched between the first and second positions, partially blocking the front air outlet 142 and also partially blocking the lower air outlet 112. Therefore, the airflow will pass through both the front air outlet duct 140 and the lower air outlet 112. At this time, the ratio of the front airflow from the front air outlet duct 140 to the lower airflow from the lower air outlet 112 can be controlled.

[0059] like Figures 2 to 5 and Figure 8 As shown, optionally, the air duct plate 300 includes a switching plate body 310. When the air duct plate 300 is in the second position, the upper surface of the switching plate body 310 smoothly transitions with the front surface of the rear air duct wall 113 of the fan outlet air duct 111.

[0060] This configuration allows the airflow from the rear of the fan assembly 200 to be guided by the rear duct wall 113 of the fan outlet duct 111, and then further guided by the upper surface of the switching plate 310 and blown into the front duct inlet 142. The airflow is continuously and stably guided by the rear duct wall 113 of the fan outlet duct 111 and the switching plate 310, thereby reducing the consumption of airflow inside the air conditioner, improving airflow efficiency, and reducing noise.

[0061] Specifically, the rear duct wall 113 of the fan outlet duct 111 has an arc-shaped protrusion that extends rearward, meaning that as the height decreases, the angle between the rear of the fan outlet duct 111 and the horizontal plane becomes smaller. The switching plate 310 is also arc-shaped, with its opening facing upwards. After the airflow passes through the switching plate 310, the airflow direction smoothly changes from forward and downward to forward and upward. When the switching plate 310 is in the second position, the rear bottom of the fan outlet duct 111 and the rear of the upper surface of the switching plate 310 are at the same angle, forming a consistent continuous arc.

[0062] like Figure 8As shown, optionally, when the air duct plate 300 is in the second position, the upper surface of the switching plate 310 and the rear surface of the lower air duct wall 143 of the front air outlet duct 140 smoothly transition.

[0063] This configuration allows for continuous and stable airflow when the air from the fan assembly 200 enters the front air outlet duct 140 after being guided by the upper surface of the switching plate 310. This reduces the consumption of airflow inside the air conditioner, improves airflow efficiency, and reduces noise.

[0064] Specifically, the lower air duct wall 143 of the front air outlet duct 140 has an arc-shaped protrusion that protrudes forward and downward. That is, as the height increases, the angle between the lower arm of the front air outlet duct 140 and the horizontal becomes larger and larger.

[0065] like Figure 5 and Figure 6 As shown, optionally, each sub-guide cavity is independently provided with a fan outlet, and a fan assembly 200 is independently provided above the fan outlet.

[0066] By independently setting air outlets in each sub-guide cavity and independently setting fan assemblies 200, different fan assemblies 200 can be controlled at different speeds to make the airflow speed of each sub-guide cavity different, thereby meeting the user's needs for different wind speeds in different areas.

[0067] Figure 10 This is a schematic diagram of the air duct plate in the indoor unit of a wall-mounted air conditioner provided in Embodiment 1 of this utility model. Figures 2 to 10 As shown, optionally, the fan assembly 200 is arranged in a vertical direction, the fan assembly 200 is a mixed flow fan, the rear air duct wall 113 of the fan outlet duct 111 is provided with a first guide rib 114; the side of the air duct plate 300 facing the front outlet duct 140 is provided with a second guide rib 320. Along the flow direction of the air outlet airflow of the fan assembly 200, at least a portion of the second guide rib 320 gradually moves away from the axis of the fan assembly 200 in the length direction of the wall-mounted air conditioner indoor unit, and at least a portion of the second guide rib 320 is correspondingly arranged with the first guide rib 114.

[0068] By setting the first guide rib 114 and the second guide rib 320, the air outlet at the rear of the fan assembly 200 can be guided to deviate from the axis of the fan assembly 200 and disperse along the left and right directions of the wall-mounted air conditioner indoor unit, so as to make full use of the length of the wall-mounted air conditioner indoor unit and improve the uniformity of the air outlet along the length of the wall-mounted air conditioner indoor unit.

[0069] Specifically, in this embodiment, the fan assembly 200 uses two mixed-flow fans, which are arranged along the length of the wall-mounted air conditioner indoor unit. Corresponding to these two mixed-flow fans, a first guide rib 114 and a second guide rib 320 are provided along the length of the rear duct wall 113 of the fan outlet duct 111 and the duct plate 300. The extension direction of the first guide rib 114 can be perpendicular to the left-right direction of the wall-mounted air conditioner indoor unit, or it can be arranged with gradually increasing intervals from top to bottom. Along the airflow direction in the duct plate 300, the angle between the extension direction of the second guide rib 320 and the left-right direction gradually decreases, thus gradually diffusing the airflow direction to the left and right sides, allowing for more uniform airflow from the front air outlet 141. For example, in this embodiment, if six first guide ribs 114 are provided for each mixed-flow fan, then six second guide ribs 320 are also provided, corresponding one-to-one with the first guide ribs 114. If the first guide rib 114 is arranged in parallel, the second guide rib 320 extends in a direction perpendicular to the left and right directions at its rear end corresponding to the first guide rib 114.

[0070] like Figures 1 to 9 As shown, optionally, a lower air outlet duct 500 is connected to the lower part of the lower air outlet 112.

[0071] By setting a lower air outlet duct 500 at the lower air outlet 112, the air outlet duct can be used to guide the airflow leaving the lower air outlet 112. Moreover, the airflow does not come into contact with the air outside the indoor unit of the wall-mounted air conditioner in the air outlet duct. The length of the airflow with the pressure in the upstream direction being greater than the air pressure in the downstream direction will also increase, thereby increasing the airflow speed. This is especially beneficial for the hot air blown out by the air conditioner in heating mode to move downward, thereby improving the temperature uniformity of the indoor space and enhancing the user experience.

[0072] Furthermore, the outer periphery of the lower air outlet duct 500 can also be fitted with decorative structures, such as the circumference of the lower air outlet duct 500 being shaped like the circumference of a cylindrical helical gear. A light strip 510 can also be installed at the center of its height. The light strip 510 can display different information based on its brightness and color. For example, warm colors such as red, orange, or yellow can indicate that the air conditioner is in heating mode, while cool colors such as green or blue can indicate that the air conditioner is in cooling mode, and the brightness of the color can indicate the temperature.

[0073] Example 2:

[0074] 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.

[0075] 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.
