Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and more specifically, to a wall-mounted air conditioner. Background Technology

[0002] As living standards continue to improve, people are increasingly demanding greater comfort, energy efficiency, and smart features from air conditioning equipment. Currently, most air conditioning systems have relatively simple air supply methods and air outlet directions, making it difficult to flexibly adjust them according to user needs. In particular, during cooling and heating modes, the airflow distribution often fails to meet the requirements of actual usage scenarios.

[0003] For example, in heating mode, cold air is usually heated and concentrated in the upper part of the room, resulting in lower temperatures in the lower part and uneven indoor temperature distribution; while in cooling mode, cold air tends to concentrate in the lower part of the room, affecting the overall cooling effect. Furthermore, in traditional air conditioning systems, the fixed cross-flow duct structure cannot achieve multi-directional airflow, limiting the user experience. Utility Model Content

[0004] This application provides a wall-mounted air conditioner. By incorporating a movable air guide plate assembly inside the casing, it can close the bottom of the air guide cavity and open the lower air outlet in a first movable position to form a lower air outlet duct, and open the bottom of the air guide cavity and close the lower air outlet in a second movable position to form a front air outlet duct. This allows a single fan system to switch between upper and lower air outlets. Simultaneously, the mechanical seals of the lower and front baffle assemblies for non-working air outlets effectively block any residual gaps that the air guide plate assembly cannot completely seal, preventing cross-contamination and leakage of cold or hot air within the casing. This ensures that when air is discharged downwards, all airflow is directed downwards through the lower air outlet, and when air is discharged forwards, all airflow is directed forwards through the front air outlet.

When the air guide plate assembly is in the second active position, the upper end of the arc-shaped air guide plate is located at the front shell position of the casing, and the lower end of the arc-shaped air guide plate is located at the lower edge of the outlet of the fan system.

[0024] Example like Figures 1-3 As shown, the first aspect of this application provides a wall-mounted air conditioner, including: The housing 10 has a lower air outlet 101 on its bottom side and a front air outlet 102 on its upper front side. The heat exchanger 20 and the fan system 30 are arranged vertically inside the casing 10, with the heat exchanger 20 mounted on the outer periphery of the fan system 30. Panel 40 is located inside the housing 10 and is situated between the front side of the heat exchanger 20 and the front side of the housing 10. The side of the panel 40 facing the heat exchanger 20 defines an air inlet cavity 50 between the heat exchanger 20 and the top of the housing 10. The side of the panel 40 away from the heat exchanger 20 defines a flow guide cavity 60 between the panel 40 and the housing 10. The top end of the flow guide cavity 60 is connected to the front air outlet 102, and the bottom end of the flow guide cavity 60 is configurably connected to the outlet of the fan system 30. The air guide plate assembly 70 is movably disposed on the outlet side of the fan system 30. When in motion, the air guide plate assembly 70 has at least a first movable position and a second movable position. When the air guide plate assembly 70 is in the first movable position, the air guide plate assembly 70 closes the connection between the bottom end of the guide cavity 60 and the outlet of the fan system 30, and simultaneously guides the connection between the outlet of the fan system 30 and the lower air outlet 101, so that a lower air outlet duct is formed between the outlet of the fan system 30 and the lower air outlet 101. When the air guide plate assembly 70 is in the second movable position, the air guide plate assembly 70 connects the bottom end of the guide cavity 60 to the outlet of the fan system 30, and simultaneously closes the connection between the outlet of the fan system 30 and the lower air outlet 101, so that a front air outlet duct is formed between the outlet of the fan system 30 and the front air outlet 102. The wind deflector assembly 80 includes a lower wind deflector assembly 801 disposed at the lower air outlet 101 and a front wind deflector assembly 802 disposed at the front air outlet 102. When the wall-mounted air conditioner blows air downwards through the lower air outlet duct, the lower baffle assembly 801 opens the lower air outlet 101, and the front baffle assembly 802 closes the front air outlet 102. When the wall-mounted air conditioner blows air forward through the front air outlet duct, the front baffle assembly 802 opens the front air outlet 102, and the lower baffle assembly 801 closes the lower air outlet 101.

[0025] In this embodiment, a movable air guide plate assembly 70 is provided inside the casing 10 of the wall-mounted air conditioner. In the first movable position, it closes the bottom end of the guide cavity 60 and opens the lower air outlet 101 to form a lower air outlet duct. In the second movable position, it opens the bottom end of the guide cavity 60 and closes the lower air outlet 101 to form a front air outlet duct. This allows a single fan system 30 to switch between upper and lower air outlets. At the same time, the mechanical seal of the non-working air outlets by the lower baffle assembly 801 and the front baffle assembly 802 effectively blocks any residual gaps that the air guide plate assembly 70 cannot completely seal, preventing cold or hot air from leaking into the casing 10. This ensures that when the air outlet is lowered, all airflow is sent downward through the lower air outlet 101, and when the air outlet is fronted, all airflow is sent forward through the front air outlet 102. This improves the reliability, sealing, and user comfort of the airflow direction switching without adding an additional fan.

[0026] Furthermore, in some possible implementations, when the lower air outlet 101 is closed, the lower air outlet 101 can be completely concealed within the housing 10. and / or When the front windshield assembly 802 closes the front air vent 102, the front windshield assembly 802 can be completely concealed in the housing 10.

[0027] In this embodiment, the lower wind deflector assembly 801 and the front wind deflector assembly 802 are designed to be completely concealed within the housing 10 when the corresponding air outlets are closed. This results in a cleaner and flatter appearance for the air conditioner when not in use, avoiding the visual abruptness of traditional exposed wind deflectors. Simultaneously, this concealed design reduces the space occupied by the wind deflector assemblies within the housing, providing greater flexibility for the layout of other components and further optimizing the overall structural design of the air conditioner.

[0028] Furthermore, in some possible embodiments, the lower baffle assembly 801 includes a lower baffle that can be controlled to translate along the front-rear direction of the housing 10 to open or close the lower air outlet 101 by the front-rear translational movement. and / or The front windshield assembly 802 includes a front baffle that can be controlled to move horizontally along the housing 10 to open or close the front air outlet 102 by the vertical movement.

[0029] In this embodiment, precise control of the air outlet is achieved by designing the lower baffle of the lower baffle assembly 801 to translate along the front-rear direction of the housing 10, and the front baffle of the front baffle assembly 802 to translate along the vertical direction of the housing 10. This translational motion makes the movement path of the baffle clearer and more stable, facilitating precise driving by a motor or mechanical device, thereby improving the reliability and convenience of the air outlet opening and closing operation. Furthermore, the translational motion design makes the movement trajectory of the baffle more compact when opening or closing the air outlet, avoiding the extra space required for complex rotation or folding movements. This design not only saves space inside the housing but also makes the entire air conditioner structure more compact, contributing to a thinner wall-mounted design and improving the product's aesthetics and installation flexibility. Moreover, compared to complex rotation or oscillation movements, translational motion generally has higher stability and a lower risk of mechanical failure. This design reduces friction and wear between moving parts, extends the service life of the baffle assembly, and reduces the risk of air outlet sealing failure or inability to open and close properly due to mechanical failure. Furthermore, the sliding baffle moves more smoothly and quietly when opening or closing the air outlet, without producing noticeable mechanical noise or vibration. This design enhances the user's comfort experience when using the air conditioner, especially in scenarios requiring a quiet environment, such as bedrooms or offices.

[0030] Furthermore, in some possible embodiments, the housing 10 includes a bottom housing with a lower air outlet 101 and a front housing with a front air outlet 102. The bottom shell has an internal sliding track 103 that connects to the lower air outlet 101 and extends back and forth. The lower baffle can be controlled to slide and translate back and forth within the bottom shell sliding track 103. and / or The front shell has an internal sliding track 104 that connects to the front air outlet 102 and extends vertically. The front baffle can be controlled to slide vertically within the front shell sliding track 104.

[0031] In this embodiment, a minimalist mechanism consisting of a built-in sliding rail and a sliding baffle completely conceals the "opening / closing of the vent" action within the thickness of the housing 10. The bottom housing sliding rail 103 allows the lower baffle to move linearly forward and backward, while the front housing sliding rail 104 allows the front baffle to move linearly up and down. Neither of these mechanisms flips outward or protrudes from the body contour. This results in a single-stage effect: when the vent is closed, the appearance is flat and without gaps, preventing dust and pinching; when the vent is open, the baffle completely yields, leaving the air duct section unobstructed and ensuring no reduction in airflow. Simultaneously, the rail provides rigid guidance, ensuring smooth baffle movement, low noise, and long lifespan. Furthermore, all parts are pre-installed inside the bottom / front housing, requiring only three steps in the final assembly process: insertion, sliding, and locking. This significantly improves production efficiency and reduces after-sales failure rates.

[0032] Furthermore, in some possible embodiments, the lower air outlet 101 includes a front edge and a rear edge opposite to each other in the front-rear direction of the bottom shell, and the bottom shell sliding track 103 has a track opening at the rear edge position that communicates with the lower air outlet 101. and / or The front air outlet 102 includes an upper edge and a lower edge that are opposite each other in the vertical direction of the front housing, and the front housing sliding track 104 has a track opening at the lower edge that connects to the front air outlet 102.

[0033] In this embodiment, the bottom shell sliding track 103 is located near the rear side of the housing, which allows the lower air outlet 101 to have sufficient space to be located near the front of the housing. Similarly, in this embodiment, the front shell sliding track 104 is located near the lower side of the housing, which allows the front air outlet 102 to have sufficient space to be located near the top of the housing.

[0034] Furthermore, in some possible embodiments, the panel body 40 is configured as an arc-shaped plate protruding towards the rear side of the housing 10, the lower end of the panel body 40 is connected to the volute tongue 301 at the outlet of the fan system 30, and the upper end of the panel body 40 extends arc-shaped to the upper edge of the front air outlet 102.

[0035] In this embodiment, the panel body 40 is made into an arc-shaped plate, with its lower end abutting against the volute tongue 301 and its upper end extending to the upper edge of the front air outlet 102. Thus, a single part can simultaneously perform the two functions of "front air duct profile + air inlet expansion": the arc-shaped inner surface smoothly guides the airflow to the front air outlet 102, reducing eddies; the arc-shaped outer surface allows the upper air inlet area to naturally expand outward, increasing the air inlet area.

[0036] Furthermore, in some possible embodiments, the outlet of the fan system 30 includes an upper edge and a lower edge of the outlet opposite to each other in the vertical direction of the housing 10, a volute tongue 301 is formed at the upper edge of the outlet, and the air guide plate assembly 70 includes an arc-shaped air guide plate rotatably disposed outside the outlet of the fan system 30. When the air guide plate assembly 70 is in the first active position, the upper end of the arc-shaped air guide plate is located at the volute tongue 301 at the upper edge of the outlet of the fan system 30, and the lower end of the arc-shaped air guide plate is located at the front edge of the lower air outlet 101 near the front of the casing 10. When the air guide plate assembly 70 is in the second active position, the upper end of the arc-shaped air guide plate is located at the front shell position of the housing 10, and the lower end of the arc-shaped air guide plate is located at the lower edge of the outlet of the fan system 30.

[0037] In this embodiment, a single arc-shaped air guide plate can "complete" different volute profiles in two positions: In the first position, the upper end of the plate overlaps with the volute tongue 301, and the lower end overlaps with the front edge, instantly forming a complete downward-exiting volute, with airflow adhering to the wall and downward without leakage; In the second position, the upper end of the plate flips to the front shell, and the lower end overlaps with the lower edge of the outlet, immediately forming a front-exiting volute, with airflow guided accordingly to 102. Thus, a bidirectional complete volute is achieved with a single component, eliminating the need for additional dampers or foam inserts, without airflow reduction or noise increase, and the switching process involves only one rotation, resulting in an extremely simple structure and high reliability.

[0038] Furthermore, in some possible implementations, the wall-mounted air conditioner also includes: The front air chamber plate 90 extends vertically and is disposed on the inner side wall of the front shell, and defines a guide cavity 60 between the front air chamber plate 40 and the front air chamber plate 40. The upper end of the front air cavity plate 90 extends to the lower edge of the front air outlet 102, wherein when the air guide plate assembly 70 is in the second active position, the upper end of the arc-shaped air guide plate in the air guide plate assembly 70 abuts against the lower end of the front air cavity plate 90.

[0039] In this embodiment, a front air chamber plate 90 is added, forming a vertically extending guide cavity 60 between it and the arc-shaped panel 40, and a "hard boundary" is formed at the lower edge of the front air outlet 102. When the arc-shaped guide plate is in the second movable position, its upper end just overlaps the lower end of the front air chamber plate 90, thereby connecting the entire air duct from the fan outlet to the front air outlet 102 into a continuous and smooth "volute-like" channel. In this way, the airflow no longer passes through any steps or open bends, completely eliminating eddies and backflow, resulting in a longer front air outlet range and lower noise. At the same time, the front air chamber plate 90, as a structural component, strengthens the rigidity of the front shell, reduces resonance, and the appearance surface does not require additional screws or foam filling, achieving a triple benefit of performance, strength, and simple design.

[0040] Furthermore, in some possible implementations, the top of the housing 10 is also provided with an air inlet 105; Wall-mounted air conditioners also include: The front air guide plate 100 is rotatably disposed at the top outlet position of the air guide cavity 60, and the rotation position of the front air guide plate 100 is close to the upper edge of the front air outlet 102. in When the wall-mounted air conditioner discharges air through the front air outlet 102, the front air guide plate 100 rotates toward the outside of the casing 10 so as to guide the airflow from the front air outlet 102. When the wall-mounted air conditioner closes the front air outlet 102 via the front windshield assembly 802, the front air deflector 100 rotates toward the inside of the housing 10 to avoid the front windshield assembly 802.

[0041] In this embodiment, a rotatable front air guide plate 100 is added to the inner side of the upper edge of the front air outlet 102: when the air outlet is open, it rotates outward, pressing the rising cold air diagonally downward, extending the air delivery distance and preventing the airflow from dissipating against the top; when the front air outlet is closed, it rotates inward, making room for the sliding track, so that the front air deflector assembly 802 can be completely concealed. That is, the dual functions of "external air guidance and internal avoidance" are achieved through the same part, without increasing the thickness or damaging the appearance, improving cooling comfort, and ensuring the flatness and sealing of the air outlet after it is closed.

[0042] It should be noted that since the front air vent 102 is close to the upper part of the housing 10 and is close to the air inlet 105 at the top of the housing 10, the front air guide plate 100 is set at the front air vent 102. This not only extends the airflow guiding stroke and makes the airflow blow forward a longer distance, but also effectively prevents the upper airflow from returning and reduces the risk of airflow short circuit.

[0043] Furthermore, in some possible implementations, an airflow gap d is formed between the rotational position of the front guide vane 100 and the top wall position of the guide cavity 60, where 3mm≤d≤7mm; When the front air guide plate 100 flips outward to guide the airflow to the outside of the housing 10, part of the airflow in the guide cavity 60 is guided into the room by the lower plate surface of the front air guide plate 100, and another part of the airflow flows through the air gap and is guided into the room by the upper plate surface of the front air guide plate 100.

[0044] In this embodiment, the gap d between the front air guide plate 100 and the top wall of the guide cavity 60 is locked at 3mm-7mm. This way, when air is expelled forward, a portion of the airflow blows forward along the lower surface of the plate, while a small portion flows out synchronously through the gap d, adhering to the upper surface of the plate. This ensures that the upper and lower surfaces of the air guide plate are cooled by the same cold air without any temperature difference. Simultaneously, the two airflows converge at the edge of the plate, forming a continuous wall-attached jet. This ensures that the upper and lower surfaces of the air guide plate are at the same temperature, completely eliminating condensation and eliminating the need for insulation sponge and heating wire. The small gap airflow not only does not reduce the main airflow but also enhances the wall-attached effect, resulting in farther and more uniform air delivery, achieving a simultaneous effect of anti-condensation and high-performance air guidance.

[0045] Furthermore, in some possible implementations, the wall-mounted air conditioner also includes a data acquisition module and a control module. The data acquisition module is used to acquire the indoor ambient temperature T1, and the control module is used to control the air conditioner to discharge air through the lower air outlet 101 and / or through the front air outlet 102 according to the indoor ambient temperature T1. Wall-mounted air conditioners must have at least a heating mode and a cooling mode; In heating mode, the wall-mounted air conditioner discharges air through the lower air outlet 101; In cooling mode, the control module is used to control the air conditioner to discharge air through the lower air outlet 101 or through the front air outlet 102 based on the difference △T between the target temperature T0 and the indoor ambient temperature T1. in; When △T≤ preset difference, the control module controls the wall-mounted air conditioner to discharge air through the front air outlet 102; When △T > preset difference, the control module controls the wall-mounted air conditioner to discharge air through the lower air outlet 101.

[0046] In this embodiment, the switching between upper and lower air outlets is entirely automated by the data acquisition and control modules: In heating mode, the lower air outlet 101 is the default outlet, utilizing the natural rise of hot air to quickly warm the activity area; in cooling mode, when ΔT ≤ a preset difference, the control module immediately switches to the front air outlet 102, causing the cold air to rise first and then descend evenly, avoiding direct airflow onto the human body; only when ΔT > a preset difference and rapid cooling is required is the lower air outlet 101 briefly activated to blow air directly onto the ground. This eliminates the need for manual selection by the user, automatically matching the optimal airflow organization based on the room temperature deviation, achieving a balance of rapid cooling, draft-free operation, energy saving, and comfort, while reducing the number of compressor start-stop cycles and extending the overall lifespan of the machine. Preferably, the preset difference is 1℃.

[0047] Of course, if the user does not select the automatic control mode, they can manually select "downward airflow" or "upward airflow".
