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, wall-mounted air conditioner indoor units are roughly rectangular in shape and are typically installed on the upper part of a room's wall to circulate air and improve indoor air quality, such as temperature and humidity. While some air conditioners incorporate display frames to hold ornaments or decorations outside the main unit (e.g., below the unit) to enhance their appearance, these frames can obstruct airflow from the bottom vents, potentially affecting the air conditioner's performance. 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 of the impact of existing display cavities on downward airflow.

[0004] The first aspect of this utility model provides a wall-mounted air conditioner indoor unit, including a main unit module and a lower frame. The lower frame is connected to the bottom of the main unit module and located below the main unit module. The lower frame and the main unit module form a display cavity. The lower wall of the main unit module is provided with a lower air outlet, and the lower frame is provided with an air supply outlet opposite to the lower air outlet. The display cavity is provided with an air supply duct that connects the lower air outlet and the air supply outlet.

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

[0006] By installing an air supply duct between the lower air outlet of the main unit module and the air inlet of the lower frame, the air outlet from the lower air outlet can be directly guided to the air inlet through the air supply duct. Therefore, the air outlet from the lower air outlet will not interfere with the lower frame, nor will it affect the exhibits in the display cavity, thus improving airflow efficiency. Furthermore, by installing the air supply duct, the length of the section where the pressure upstream of the airflow direction is greater than the pressure downstream can be increased. This extends the acceleration phase of the airflow, which is beneficial for increasing airflow velocity. It is particularly beneficial for the downward movement of hot air blown out by the air conditioner in heating mode, thereby improving the temperature uniformity of the indoor space and enhancing the user experience.

[0007] In an optional technical solution, the air supply duct includes a duct body and an air supply support part. The air supply support part is fixedly disposed relative to the duct body. The air supply support part is rotatably supported on a fixed support part. The fixed support part is fixedly disposed relative to the lower frame and is concentrically disposed with the center of the air supply outlet.

[0008] The cylinder is supported by the air duct support, and the air duct support is concentric with the center of the air outlet. Although friction may be generated when the fixed support rotates to support the air duct support, the friction force is small and the friction torque is small because the location of the friction force is close to the rotation axis of the cylinder. Whether the air duct is actively driven or rotated by the air outlet, it helps to reduce the resistance of the air duct rotation.

[0009] In an optional technical solution, the fixed support part includes an upper support part and / or a lower support part. The upper support part is rotatably engaged with the top end of the air duct support part, and the upper support part is located at the center of the lower air outlet. The lower support part is rotatably engaged with the bottom end of the air duct support part, and the lower support part is located at the center of the air outlet.

[0010] By setting up upper and lower support parts, the upper and lower ends of the air duct support part can be limited simultaneously. Even if the rotation of the air duct encounters an unbalanced force, the upper and lower support parts are relatively far apart, and the upper and lower support parts only need to generate a small force to balance the external interference force.

[0011] In an optional technical solution, the lower support is fixedly connected to the air outlet via a first spoke; and / or, the upper support is fixedly connected to the lower air outlet via a second spoke;

[0012] And / or, of the lower support part and the air duct support part, one is provided with a first support protrusion and the other is provided with a first limiting hole, and the first support protrusion and the first limiting hole are rotatably connected.

[0013] And / or, of the upper support part and the air duct support part, one is provided with a second support protrusion and the other is provided with a second limiting hole, and the second support protrusion and the second limiting hole are rotatably connected.

[0014] By setting a first spoke to fix the lower support to the air outlet, and using a second spoke to connect the upper and lower support, not only can the upper and lower support be supported, but the upper and lower ends of the air duct support can also be supported, ensuring the stability of the rotation axis of the air duct. Moreover, the cooperation of the first support protrusion and the first inner limiting hole can prevent radial movement between the bottom of the lower support and the air duct support. Similarly, the cooperation of the second support protrusion and the second inner limiting hole can prevent radial movement between the top of the upper support and the air duct support.

[0015] In an optional technical solution, the wall-mounted air conditioner indoor unit also includes a fan duct drive motor, which is installed on one of the bottom of the main unit module and the lower frame, and is connected to the air supply duct in a driving connection.

[0016] By setting up a fan drive motor, the fan can be actively driven to rotate, thereby reducing the energy loss of the airflow caused by driving the fan to rotate, which helps to ensure the downward movement distance of the airflow.

[0017] In an optional technical solution, the cylinder is fixedly connected to the air duct support via blades, and the blades are configured to drive the cylinder to rotate under the action of the airflow or be driven to rotate by the cylinder.

[0018] By setting blades, the force of the airflow on the blades can be converted into torque that drives the air supply tube to rotate, or the rotation of the air supply tube can be used to drive the blades to apply force to the airflow to enhance the airflow.

[0019] In an optional technical solution, a transparent tube is provided outside the air supply duct, and at least one of the bottom of the main unit module and the lower frame is fixedly connected to the transparent tube.

[0020] By installing a fixed transparent tube, the air supply tube can be shielded, protecting it from accidental contact and potential injury to the user. It also prevents dust from accumulating on the air supply tube's surface. If dust does accumulate on the fixed transparent tube, it can be easily removed by wiping.

[0021] In an optional technical solution, the air supply duct is rotatably arranged relative to the lower frame, and a light-emitting element is fixedly installed on the transparent tube.

[0022] By placing the light-emitting element on the transparent inner cylinder and keeping it fixed without rotating, it is easy to connect the light strip to the power supply.

[0023] In an optional technical solution, at least one of the bottom of the host module and the lower frame is fixedly connected to the air supply duct, and the air supply duct is provided with a light-emitting element.

[0024] The air supply duct is fixedly connected to at least one of the bottom and lower frame of the main unit module, so that there is no wear between the air supply duct and the connecting parts, thereby improving the service life of the wall-mounted air conditioner indoor unit.

[0025] The second aspect of this utility model is to provide an air conditioner to solve the technical problem of the impact of the display cavity on downward airflow.

[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

It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0046] Example 1:

[0047] Figure 1 This is a three-dimensional sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model. Figure 2 This is a three-dimensional sectional view of the indoor unit of the wall-mounted air conditioner provided in Embodiment 1 of this utility model, omitting the air supply duct. Figure 3 This is a cross-sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model. Figure 4 This is a cross-sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model, omitting the air supply duct. Figures 1-4As shown, the wall-mounted air conditioner indoor unit provided in Embodiment 1 of this utility model includes a main unit module 100 and a lower frame 200. The lower frame 200 is connected to the bottom of the main unit module 100 and is located below the main unit module 100. The lower frame 200 and the main unit module 100 form a display cavity. The lower wall of the main unit module 100 is provided with a lower air outlet 110, and the lower frame 200 is provided with an air supply outlet 211 opposite to the lower air outlet 110. An air supply duct 300 connecting the lower air outlet 110 and the air supply outlet 211 is provided in the display cavity.

[0048] By installing an air supply duct 300 between the lower air outlet 110 of the main unit module 100 and the air outlet 211 of the lower frame 200, the air outlet 110 can be directly guided to the air outlet 211 through the air supply duct 300. Therefore, the air outlet 110 will not interfere with the lower frame 200, nor will it affect the exhibits in the display cavity, thus improving air outlet efficiency. Furthermore, by installing the air supply duct 300, the length of the section where the pressure upstream of the air outlet direction is greater than the pressure downstream can be increased. This extends the acceleration phase of the air outlet, which is beneficial for increasing the air outlet speed. It is particularly beneficial for the downward movement of hot air blown out by the air conditioner in heating mode, thereby improving the temperature uniformity of the indoor space and enhancing the user experience.

[0049] 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 intake area of ​​the fan assembly 123. 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 123 to be discharged from below the fan assembly 123 and flow into the fan outlet duct.

[0050] In this embodiment, two fan assemblies 123 can be provided. The fan assemblies 123 can be mixed-flow fans, which are arranged vertically along their axes. The two mixed-flow fans are arranged along the length of the indoor unit of the wall-mounted air conditioner, i.e., in the left-right direction. At the bottom of the main unit module 100, corresponding to the fan assemblies 123, two lower air outlets 110 are provided.

[0051] In this embodiment, the left and right side walls of the main unit module 100 extend downwards naturally and are fixedly connected to the base plate 210. The side walls extending downwards from the bottom of the main unit module 100 and the base plate 210 together constitute the lower frame 200. Two air outlets 211 are provided on the base plate 210, corresponding to the lower air outlet 110. The positions of the air outlets 211 correspond to those of the lower air outlet 110.

[0052] Figure 5This is a schematic diagram of the air supply duct in the indoor unit of a wall-mounted air conditioner provided in Embodiment 1 of this utility model. Figure 6 This is a schematic diagram of the air supply duct in the indoor unit of the wall-mounted air conditioner provided in Embodiment 1 of this utility model, viewed from another direction. Figures 1 to 6 As shown, optionally, the air supply duct 300 includes a duct body 310 and an air supply duct support 320. The air supply duct support 320 is fixedly disposed relative to the duct body 310. The air supply duct support 320 is rotatably supported on a fixed support. The fixed support is fixedly disposed relative to the lower frame 200 and is concentrically disposed with the center of the air supply port 211.

[0053] The cylinder 310 is supported by the air duct support 320, and the air duct support 320 is concentrically set with the center of the air outlet 211. Although friction may be generated when the fixed support rotates to support the air duct support 320, the distance between the location where the friction force is generated and the rotation axis of the cylinder 310 is relatively close, so the lever arm of the friction force is small and the friction torque is small. Whether the air duct 300 is actively driven or driven by the air outlet 110, it helps to reduce the resistance of the rotation of the air duct 300.

[0054] By setting the air supply duct 300 to rotate relative to the main unit module 100, the air outlet speed of the fan component 123 in the main unit module 100 can be linked to the rotation speed of the air supply duct 300. The greater the air outlet speed or air volume, the faster the air supply duct 300 rotates, thus allowing the air speed to be displayed in a visually visible way.

[0055] Specifically, a cylindrical helical gear-like shape can be set on the outer side of the cylinder 310. The faster the wind speed, the faster the outer circumference of the cylindrical helical gear-like shape of the cylinder 310 rotates. Users can qualitatively determine the wind speed by observing the rotation speed of the outer circumference of the cylinder 310.

[0056] like Figures 1 to 6 As shown, optionally, the fixed support part includes an upper support part 130 and a lower support part 140. The upper support part 130 is rotatably engaged with the top end of the air duct support part 320 and is located at the center of the lower air outlet 110. The lower support part 140 is rotatably engaged with the bottom end of the air duct support part 320 and is located at the center of the air outlet 211.

[0057] By setting the upper support part 130 and the lower support part 140, the upper and lower ends of the air duct support part 320 can be limited simultaneously. Even if the rotation of the air duct 300 encounters an unbalanced force, the upper support part 130 and the lower support part 140 are relatively far apart, and the upper support part 130 and the lower support part 140 only need to generate a small force to balance the external interference force.

[0058] Of course, in this embodiment, the fixed support includes an upper support 130 that rotatably engages with the top of the air duct support 320 and a lower support 140 that rotatably engages with the bottom of the air duct support 320, so as to provide support for the air duct 300 from the top and bottom. Alternatively, in another implementation, if the air duct 300 is driven by a motor, it can be supported only at the top of the air duct support 320 by the upper support 130 or only at the bottom of the air duct support 320 by the lower support 140. The other end of the air duct support 320 is radially limited by its fixed connection to the output shaft of the motor.

[0059] like Figures 1 to 6 As shown, optionally, the lower support 140 is fixedly connected to the air outlet 211 via the first spoke 141; the upper support 130 is fixedly connected to the lower air outlet 110 via the second spoke 131.

[0060] Of the lower support part 140 and the air duct support part 320, one is provided with a first support protrusion 321 and the other is provided with a first limiting hole 142. The first support protrusion 321 and the first limiting hole 142 are rotatably connected.

[0061] Of the upper support part 130 and the air duct support part 320, one is provided with a second support protrusion 132 and the other is provided with a second limiting hole 322. The second support protrusion 132 and the second limiting hole 322 are rotatably connected.

[0062] By setting the first spoke 141 to fix the lower support 140 to the air outlet 211, and using the second spoke 131 to connect the upper support 130 and the lower support 140, not only can the upper support 130 and the lower support 140 be supported, but the upper and lower ends of the air duct support 320 can also be supported, ensuring the stability of the rotation axis of the air duct 300. Moreover, by using the cooperation of the first support protrusion 321 and the first inner limiting hole, radial movement between the bottom of the lower support 140 and the air duct support 320 can be prevented. Similarly, by using the cooperation of the second support protrusion 132 and the second inner limiting hole, radial movement between the top of the upper support 130 and the air duct support 320 can be prevented.

[0063] Specifically, in this embodiment, the lower support portion 140 is fixedly connected to the air outlet 211 via four first spokes 141. The four spokes are evenly distributed along the circumference of the lower support portion 140, or more specifically, they can be distributed in the front, rear, left, and right directions of the lower support portion 140. The upper support portion 130 is fixedly connected to the lower air outlet 110 via four second spokes 131. The four spokes are evenly distributed along the circumference of the lower support portion 140, or more specifically, they can be distributed in the front, rear, left, and right directions of the lower support portion 140. That is, the first spokes 141 connected to the lower support portion 140 and the second spokes 131 connected to the upper support portion 130 are correspondingly arranged in the vertical direction.

[0064] In this embodiment, the first support protrusion 321 is located at the bottom of the duct support portion 320 and protrudes downward, while the first limiting hole 142 is located in the lower support portion 140 and recessed downward. The second support protrusion 132 is located at the bottom of the upper support portion 130 and protrudes downward, while the second limiting hole 322 is located at the top of the duct support portion 320 and recessed downward. In this embodiment, the bottom of the first limiting hole 142 can mate with the bottom surface of the periphery of the first support protrusion 321 to restrict the vertical position of the duct support portion 320 from bottom to top. The extreme position of the upward movement of the duct support portion 320 can be determined by the mating of the top surface of the solid surrounding the second limiting hole 322 at the top of the duct support portion 320 and the bottom surface of the solid surrounding the second support protrusion 132.

[0065] Of course, in another implementation, the positions of the first limiting hole 142 and the first supporting protrusion 321 can be interchanged, and similarly the positions of the second limiting hole 322 and the second supporting protrusion 132 can also be interchanged.

[0066] like Figure 5 and Figure 6 As shown, optionally, the cylinder 310 is fixedly connected to the air duct support 320 via blades 330. The blades 330 are configured to drive the cylinder 310 to rotate under the action of the airflow or be driven to rotate by the cylinder 310.

[0067] By setting the blades 330, the force of the airflow on the blades 330 can be converted into torque that drives the air supply duct 300 to rotate, or the rotation of the air supply duct 300 can be used to drive the blades 330 to apply force to the airflow to enhance the airflow.

[0068] Specifically, in this embodiment, the duct support 320 can be fixedly connected to the cylinder 310 by at least two evenly distributed blades 330. More specifically, in this embodiment, it can be connected by five blades 330. The root of each blade 330 is fixedly connected to the duct support 320, while the tip of each blade 330 is fixedly connected to the inner circumferential surface of the cylinder 310. More specifically, the cylinder 310, blades 330, and duct support 320 can be integrally formed. Each blade 330 intersects the axial, radial, and tangential directions of the air supply duct 300 to better convert the movement of the airflow into the rotation of the air supply duct 300.

[0069] like Figures 1 to 4 As shown, optionally, a transparent tube 400 is provided outside the air supply duct 300, and at least one of the bottom of the main unit module 100 and the lower frame 200 is fixedly connected to the transparent tube 400.

[0070] By setting a fixed transparent tube 400, the air supply tube 300 can be shielded, which protects the air supply tube 300 from accidental contact with the user and prevents injury from being pinched or hit. It also prevents dust from accumulating on the surface of the air supply tube 300. If dust accumulates on the fixed transparent tube 400, it can be removed simply by wiping.

[0071] Specifically, in this embodiment, the transparent tube 400 can be made of acrylic material, and the transparent tube 400 can be installed at the bottom of the main module 100 or the lower frame 200 by means of threaded connection, buckle, etc.

[0072] Optionally, a light-emitting element (not shown in the figure) is fixedly installed on the transparent tube 400.

[0073] By placing the light-emitting element on the transparent inner cylinder and keeping it fixed without rotating, it is easy to connect the light strip to the power supply.

[0074] Specifically, in this embodiment, the light-emitting element is a ring-shaped light strip, which can be fixed to the upper, middle, or lower part of the inner circumference of the transparent cylinder 400. Of course, in another implementation, the light strip can also be fixed to the top or bottom wall of the annular cavity space between the air supply duct 300 and the transparent cylinder 400, that is, fixed to the lower surface of the bottom of the main unit module 100 or fixed to the upper surface of the base plate 210, and located between the air supply duct 300 and the transparent cylinder 400.

[0075] Example 2:

[0076] Figure 7 This is a three-dimensional sectional view of the indoor unit of the wall-mounted air conditioner provided in Embodiment 2 of this utility model. Figure 8 This is a perspective sectional view of the wall-mounted air conditioner indoor unit provided in Embodiment 2 of this utility model, omitting the air supply duct. Figure 7 and Figure 8As shown, the difference between this embodiment and Embodiment 1 is that the wall-mounted air conditioner indoor unit also includes a duct drive motor 150. The duct drive motor 150 is installed on one of the bottom of the main unit module 100 and the lower frame 200, and the duct drive motor 150 is connected to the air supply duct 300 for transmission.

[0077] By setting the air duct drive motor 150, the air supply duct 300 can be actively driven to rotate, thereby reducing the energy loss of the airflow caused by driving the air supply duct 300 to rotate, which helps to ensure the downward movement distance of the airflow.

[0078] Specifically, in this embodiment, the duct drive motor 150 is connected to the lower air outlet 110 via multiple second spokes 131, meaning the duct drive motor 150 is installed at the bottom of the main unit module 100. The transmission part of the output shaft of the duct drive motor 150 can have a non-circular cross-section. Correspondingly, the hole at the top of the duct support 320 is also non-circular, matching the shape and size of the transmission part of the output shaft, allowing torque to be transmitted between them. Alternatively, the transmission part of the output shaft can also have a circular cross-section, but sufficient friction can be generated between the hole at the top of the duct support 320 and the transmission part of the output shaft of the duct drive motor 150 to drive the air delivery duct 300 to rotate.

[0079] Of course, in this embodiment, since the top of the duct support 320 is connected to the duct drive motor 150, the bottom of the duct support 320 can be rotatably connected to the first support. In another implementation, the duct drive motor 150 can also be mounted on the lower frame 200, with the transmission part of the output shaft of the duct drive motor 150 connected to the bottom of the duct support 320 to drive the air delivery duct 300 to rotate. The second support then limits the top of the duct support 320.

[0080] Example 3:

[0081] Figure 9 This is a cross-sectional view of the indoor unit of a wall-mounted air conditioner provided in Embodiment 1 of this utility model. Figure 9 As shown, the difference between this embodiment and Embodiment 1 and Embodiment 2 is that at least one of the bottom of the host module 100 and the lower frame 200 is fixedly connected to the air supply duct 300, and the air supply duct 300 is provided with a light-emitting element 500.

[0082] The air supply duct 300 is fixedly connected to at least one of the bottom of the main unit module 100 and the lower frame 200, so that no wear occurs between the air supply duct 300 and the connecting parts, thereby improving the service life of the wall-mounted air conditioner indoor unit.

[0083] Specifically, in this embodiment, the air supply duct 300 can be fixedly connected to the bottom of the main unit module 100, for example, by screws or by snap-fit. Since there is no need to support the air supply duct 300 in the middle, the air supply duct 300 may not have an internal air supply duct support 320, nor may it have blades 330 for connecting the air supply duct support 320 and the duct body 310. Furthermore, there is no need to provide fixed supports on the bottom of the main unit module 100 and the lower frame 200. Of course, in another implementation, the air supply duct 300 can also be fixedly connected to the lower frame 200.

[0084] Example 4:

[0085] Embodiment 4 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.

[0086] 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.
