Abstract

This invention provides a reversible airflow indoor unit and air conditioner. The reversible airflow indoor unit includes a first air outlet and a second air outlet. The first air outlet is located above the second air outlet. The first air outlet can form an upward air outlet, and the second air outlet can form a downward air outlet. When air is discharged from the first air outlet, the second air outlet can stop discharging air to form an upward airflow mode. When air is discharged from the second air outlet, the first air outlet can stop discharging air to form a downward airflow mode. The first air outlet and the second air outlet can discharge air simultaneously to form an up-and-down airflow mode. According to this invention, at least three different airflow modes—upward airflow, downward airflow, and up-and-down airflow—can be achieved. Multiple airflow modes can be selected as needed, solving the problem that existing wall-mounted air conditioners cannot provide multi-functional modes such as shower-style cooling, carpet heating, and rapid cooling / heating, resulting in low indoor comfort.

Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to an air conditioning indoor unit and an air conditioner with reversible air outlet. Background Technology

[0002] Traditional wall-mounted air conditioners typically use a single air deflector or two small air deflectors, which often result in the problem of cold air blowing directly on people. This technology no longer meets people's needs for air conditioning comfort. As people's requirements for comfort increase, the future development trend is for air conditioners to be able to quickly control the temperature and not blow cold air on people during operation.

[0003] Existing technologies include wall-mounted air conditioners with dual cross-flow top and bottom air outlets, but they can only achieve simultaneous top and bottom air outlets or only top or bottom air outlets. They cannot achieve the above multiple functions in one structure at the same time, nor can they provide multiple air outlet modes for selection. This makes it impossible for users to choose between shower-style cooling, carpet heating and rapid cooling to meet the maximum comfort level, resulting in reduced comfort.

[0004] Because existing wall-mounted air conditioners with top and bottom air outlets cannot provide multiple functions such as shower-style cooling, carpet heating and rapid cooling, this utility model researches and designs a reversible air outlet indoor unit and air conditioner.

The first air vent is provided with a first filter and a first magnetic attraction device. The first filter can move to close the first air vent to form a windless mode, and the first filter can move to open the first air vent to close the windless mode.

In the up-and-down airflow mode, both the first and second fan blades rotate.

[0015] This utility model also provides an air conditioner, which includes the aforementioned reversible air outlet indoor unit.

[0016] The reversible air outlet indoor unit and air conditioner provided by this utility model have the following beneficial effects: 1. This utility model achieves airflow modes by setting a first air outlet at the top and a second air outlet at the bottom on the indoor unit of a reversible air-discharge air conditioner. Both air outlets can discharge air, thus realizing an upward airflow mode. When only the first air outlet discharges air, an upward airflow mode can be achieved. When only the second air outlet discharges air, a downward airflow mode can be achieved. Therefore, this utility model can realize at least three different airflow modes: upward airflow, downward airflow, and both upward and downward airflow. Multiple airflow modes can be selected as needed. In particular, in bypass cooling mode, the upward airflow mode can achieve shower-like cooling of the room. In bypass heating mode, the downward airflow mode can achieve carpet-like heating of the room. In rapid cooling mode, the both upward and downward airflow modes can achieve rapid cooling of the room. In rapid heating mode, the both upward and downward airflow modes can achieve rapid heating of the room. This solves the problem in the prior art that can only simply discharge air upward or downward, and cannot achieve simultaneous airflow from the upper and lower air ducts. Furthermore, it solves the problem of a single air outlet mode that cannot achieve rapid temperature rise and fall; it effectively addresses the issue that existing wall-mounted air conditioners cannot provide multiple functions such as shower-style cooling, carpet heating, and rapid temperature rise / fall, resulting in low indoor comfort; and this invention also uses first and second filters respectively set at the first and second air outlets to form a windless air outlet mode through the structure of the filters. Moving the filters to block the air outlets (closing the air outlets) further enhances indoor comfort. When a windless mode is not needed (e.g., rapid cooling or heating is required), the filters can be opened to meet the demand for rapid cooling or heating, thus further satisfying users' cooling and heating needs under different conditions and further improving comfort; preferably, this invention uses a magnetic suction device structure to control the movement of the first and second filters to cover or not cover the first and second air outlets, achieving effective control over whether a windless mode is present.

[0017] 2. This utility model also features a third air vent located at the top of the indoor unit's casing, which allows for air intake into the unit, increasing the air volume. The third air vent and the first air vent are located on different surfaces, ensuring that the air intake of the third vent does not interfere with the air intake / exit of the first vent. This allows both vents to intake air simultaneously, and the first vent can also exhaust air while the third vent is intake, effectively achieving both upward and downward airflow modes. Furthermore, in the upward airflow mode, the lower second air vent can also intake air, further increasing the indoor unit's air volume; in the downward airflow mode, the upper first air vent can also intake air, further increasing the indoor unit's air volume. Thus, by achieving multiple airflow modes, the air volume can be further increased, improving the cooling and heating capacity of the indoor unit and enhancing energy efficiency.

[0018] 3. The present utility model further adopts a preferred arrangement of the heat exchanger, that is, at least part of the structure of the first heat exchange section is located between the third air outlet and the second air duct, at least part of the structure of the second heat exchange section is located between the first air duct and the second air duct, and at least part of the structure of the second heat exchange section is located between the third air outlet and the first air duct. This arrangement enables the intake air from the third air outlet to pass through the heat exchange of the first heat exchange section to the greatest extent during the process of flowing to the second air duct, and enables the intake air from the third air outlet to pass through the heat exchange of the second heat exchange section to the greatest extent during the process of flowing to the first air duct, thereby effectively reducing the situation that the air is discharged to the air outlet without being heat-exchanged by the heat exchanger, improving the heat exchange capacity of the indoor air conditioner unit, improving the heating and cooling performance, and increasing the energy efficiency of the system. The present invention also adopts the structural form of relative movement of the first panel and the second panel, which can be driven to open or close the first and second air outlets to realize the control of the air outlets. Through the structure of two magnetic attraction devices respectively arranged at the upper and lower positions, the effective targeted control of the two filter elements along with the movement of the panels is realized, and the linked control of opening or closing the air outlets and the no-wind-feeling or wind-feeling modes is achieved.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0024] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

[0027] like Figure 1-8 As shown, this utility model provides a reversible air outlet indoor unit for air conditioning, which includes: A first air vent 1 and a second air vent 2 are located above the second air vent 2. The first air vent 1 can form an upward air outlet, and the second air vent 2 can form a downward air outlet. When air is discharged from the first air vent 1, the second air vent 2 can not discharge air, thus forming an upward air outlet mode. When air is discharged from the second air vent 2, the first air vent 1 can not discharge air, thus forming a downward air outlet mode. The first air vent 1 and the second air vent 2 can discharge air simultaneously, thus forming an upward and downward air outlet mode. The first air vent 1 is provided with a first filter element 16 (preferably a filter screen) and a first magnetic attraction device. The first filter element 16 can move to close the first air vent 1 to form a windless mode, and the first filter element 16 can move to open the first air vent 1 to close the windless mode. The first magnetic attraction device can drive the first filter element 16 to move. And / or, the second air vent 2 is provided with a second filter element 17 (preferably a filter screen) and a second magnetic attraction device. The second filter element 17 can move to close the second air vent 2 to form a windless mode, and the second filter element 17 can move to open the second air vent 2 to close the windless mode. The second magnetic attraction device can drive the second filter element 17 to move.

[0028] This invention, through the aforementioned arrangement of a first air vent located at the top and a second air vent located at the bottom on the indoor unit of a reversible air-discharge air conditioner, allows for airflow from both vents, thus achieving both upward and downward airflow modes. Alternatively, airflow can be discharged only from the first vent for upward airflow mode, and only from the second vent for downward airflow mode. Therefore, this invention can achieve at least three different airflow modes: upward, downward, and both upward and downward airflow. Multiple airflow modes can be selected as needed. Specifically, in bypass cooling mode, the upward airflow mode achieves a shower-like cooling effect; in bypass heating mode, the downward airflow mode achieves a carpet-like heating effect; in rapid cooling mode, the both upward and downward airflow modes achieve rapid cooling; and in rapid heating mode, the both upward and downward airflow modes achieve rapid heating. This solves the problem in existing technologies that can only simply discharge air upwards or downwards, and cannot achieve simultaneous airflow from both the upper and lower ducts. Furthermore, it solves the problem of a single air outlet mode preventing rapid temperature rise and fall; it effectively addresses the issue of existing wall-mounted air conditioners failing to provide multi-functional modes such as shower-style cooling, carpet heating, and rapid temperature rise / fall, resulting in low indoor comfort; and this invention also utilizes first and second filters respectively installed at the first and second air outlets to create a windless air outlet mode. Moving the filters to block the air outlets (closing the air outlets) further enhances indoor comfort. The filters can also be opened when windlessness is not required (e.g., rapid cooling or heating is needed) to meet the demand for rapid cooling and heating, thus further satisfying users' cooling and heating needs under different conditions and improving comfort. Preferably, this invention uses a magnetic suction device to control the movement of the first and second filters to cover or not cover the first and second air outlets, effectively controlling whether a windless mode is present.

[0029] In some implementations... It also includes the housing 3 (or panel body), the first air duct 4, the second air duct 5, and the third air outlet 6; Both the first air duct 4 and the second air duct 5 are located inside the housing 3, and the first air duct 4 is located above the second air duct 5. One end of the first air duct 4 is located inside the housing 3, and the other end forms the first air outlet 1 and faces the room. One end of the second air duct 5 is located inside the housing 3, and the other end forms the second air outlet 2 and faces the room. The third air vent 6 is located at the top of the housing 3. Air can enter the housing 3 through the third air vent 6. The air entering through the third air vent 6 can at least partially enter the first air duct 4 and exit from the first air vent 1. The air entering through the third air vent 6 can at least partially enter the second air duct 5 and exit from the second air vent 2. The first air vent 1 and the third air vent 6 are located on different surfaces, and the second air vent 2 and the third air vent 6 are also located on different surfaces.

[0030] This utility model also utilizes the preferred structure of the third air vent located at the top of the air conditioner indoor unit's casing, which allows for air intake into the indoor unit, increasing the air volume. In particular, the third air vent and the first air vent are located on different surfaces, ensuring that the air intake of the third air vent and the air intake / exit of the first air vent are unaffected, allowing both to intake simultaneously. Furthermore, the first air vent can still exhaust air while the third air vent is intake. The third air vent and the second air vent are also located on different surfaces, ensuring that the air intake of the third air vent and the air intake / exit of the second air vent are unaffected. This effectively achieves a top-bottom air outlet mode, enabling at least three different air outlet modes: top air outlet, bottom air outlet, and top-bottom air outlet. Multiple air outlet modes can be selected as needed.

[0031] In some implementations... The first air duct 4 is located inside the housing 3 at one end, and the second air duct 5 is located inside the housing 3 at one end, and they are connected. In the top air outlet mode, the third air outlet 6 draws air into the housing 3 and directs the air into the first air duct 4. At this time, the second air outlet 2 serves as an air inlet to draw air into the second air duct 5 and further direct the air into the first air duct 4. The first air outlet 1 serves as an air outlet blowing into the room. In the down-venting mode, the third air vent 6 intakes air into the housing 3 and guides the air into the second air duct 5. At this time, the first air vent 1 serves as an air inlet to intake air into the first air duct 4 and guide the air into the second air duct 5. The second air vent 2 serves as an air outlet blowing into the room. In the top and bottom air outlet mode, the third air outlet 6 draws air into the housing 3 and can guide at least part of the air into the first air duct 4 and at least part into the second air duct 5. At this time, both the first air outlet 1 and the second air outlet 2 are air outlets.

[0032] Through the aforementioned preferred structural form, this utility model allows two air ducts to be opposite to each other and connected, enabling the airflow from the first air inlet to enter the second air duct, and the airflow from the second air inlet to enter the first air duct. In particular, in the top air outlet mode, the lower second air inlet can also intake air, further increasing the air intake volume of the indoor unit; in the bottom air outlet mode, the upper first air inlet can also intake air, further increasing the air intake volume of the indoor unit. Thus, by realizing multiple air outlet modes, the air intake volume can be further increased, improving the cooling and heating capacity of the air conditioner indoor unit and improving energy efficiency.

[0033] In some implementations... The first air vent 1 discharges air horizontally, the second air vent 2 discharges air downwards at an angle A to the vertical direction, with a range of 20°≤A≤60°, and the third air vent 6 intakes air in a downward direction along the vertical direction.

[0034] This is the preferred opening direction of the first to third air vents of this utility model, defining the air intake and exhaust directions. The upper air vent of the upper air duct is preferably designed to exhaust air horizontally forward, which can achieve the purpose and effect of shower-style cooling without the need for additional air guide plates. The second air vent of the lower air duct is designed to form a certain angle A with the vertical direction, preferably 20°≤A≤60°, which can achieve the effect of blowing air downward and forward without the need for additional air guide plates, improving the carpet-like heating effect. The third air vent is preferably designed to intake air vertically downward, which can be combined with the planar structure above the bottom shell.

[0035] In some implementations... It also includes a heat exchanger 10, which is also disposed in the housing 3, and at least a portion of the structure of the heat exchanger 10 is disposed in the region between the first air duct 4 and the second air duct 5. The heat exchanger 10 includes a first heat exchange section 11 and a second heat exchange section 12. At least a portion of the structure of the first heat exchange section 11 is located between the third air outlet 6 and the second air duct 5, and at least a portion of the structure of the second heat exchange section 12 is located between the first air duct 4 and the second air duct 5. At least a portion of the structure of the second heat exchange section 12 is located between the third air outlet 6 and the first air duct 4.

[0036] This invention further utilizes a preferred configuration of the heat exchanger, wherein at least a portion of the first heat exchange section is located between the third air outlet and the second air duct, at least a portion of the second heat exchange section is located between the first air duct and the second air duct, and at least a portion of the second heat exchange section is located between the third air outlet and the first air duct. This configuration ensures that the air entering through the third air outlet undergoes maximum heat exchange through the first heat exchange section as it flows towards the second air duct, and that the air entering through the third air outlet undergoes maximum heat exchange through the second heat exchange section as it flows towards the first air duct. This effectively reduces the amount of air discharged to the air outlet without heat exchange, thereby improving the heat exchange capacity of the indoor unit of the air conditioner, enhancing heating and cooling performance, and improving the energy efficiency of the system.

[0037] Preferably, Both the first heat exchange section 11 and the second heat exchange section 12 are straight sections. A first bend is formed at the junction of the first heat exchange section 11 and the second heat exchange section 12, so that the heat exchanger 10 forms a two-section structure with a bend.

[0038] In some implementations... It also includes a first panel 81 and a second panel 82, both of which are disposed on the side of the housing 3 facing the interior; the first panel 81 is movable to open or close the first air vent 1, and the second panel 82 is movable to open or close the second air vent 2. The end of the first heat exchange section 11 that is relatively far away from the second heat exchange section 12 is connected to the second air duct 5. The end of the second heat exchange section 12 that is relatively close to the first heat exchange section 11 is connected to the first air duct 4. A partition 7 is also provided on the side of the first panel 81 and the second panel 82 facing the inside of the housing 3. The partition 7, together with the first panel 81 and the second panel 82, forms a heat insulation cavity 9. The end of the second heat exchange section 12 that is relatively far away from the first heat exchange section 11 is connected to the partition 7.

[0039] This is a further preferred structural form of the heat exchanger of this utility model, namely, forming a two-section bent structure. The first heat exchange section is connected to the second air duct, and the second heat exchange section is connected to the first air duct. This further enhances the sealing between the two heat exchange sections and the two air ducts, ensuring that the airflow entering through the third air inlet enters the first and / or second air ducts after heat exchange in the first and second heat exchange sections to the greatest extent possible. The end of the second heat exchange section that is relatively far from the first heat exchange section is connected to a partition plate. A heat insulation cavity can be formed between the partition plate and the panel, thereby isolating and insulating the airflow in the panel and air ducts, preventing condensation from forming on the panel, and further enhancing the sealing between the heat exchange section and the two air ducts, as well as ensuring that the airflow entering through the first air inlet is maximized. The airflow that passes through the second heat exchange section to reach the second air duct or the second air outlet reaches the first air duct to the maximum extent, further improving the sealing between the multi-stage heat exchanger and the multiple air ducts. This further reduces the amount of air discharged to the air outlet without heat exchange, further improving the heat exchange capacity of the indoor unit of the air conditioner, improving heating and cooling performance, and improving the energy efficiency of the system. The invention also uses the structure of the relative movement of the first panel and the second panel to drive the opening or closing of the first and second air outlets, realizing the control of the air outlets. The structure of two magnetic attraction devices at the top and bottom respectively realizes the targeted and effective control of the two filter elements as the panels move, realizing the linkage control of opening or closing the air outlets and the presence or absence of airflow.

[0040] The heat exchanger of this invention is preferably designed in an N-shape between two air ducts, and covers the air inlets of the two air ducts respectively, ensuring that the airflow is heated by the heat exchanger and then blown into the room through the corresponding air duct.

[0041] 1. This utility model provides multiple air outlet options, which can not only meet the user's need for rapid cooling, but also provide the user with different air outlet options (the option to blow air onto people or not). The outer side of the air outlet of the upper air duct is designed with an upper filter screen; the outer side of the air outlet of the lower air duct is designed with a lower filter screen, which can achieve windless air outlet.

[0042] 2. This utility model, through the design of a sealed fit between the heat exchanger and the upper and lower air ducts, ensures that the airflow circulating in the air conditioning system can pass through the heat exchanger for heat exchange without the need to add dampers.

[0043] 3. This utility model, by designing the air outlet direction of the upper and lower air ducts, enables upward shower-style cooling and downward carpet-style heating without the need for additional air guide plates.

[0044] In some implementations... It also includes a first gear 18, a second gear 19, a first rack 20, and a second rack 21. All three gears are disposed within the insulation cavity 9. The first rack 20 is fixedly connected to the first panel 81. The first gear 18 meshes with the first rack 20, driving the first rack 20 to move (the first motor 26 drives the first gear 18 to rotate), thereby moving the first panel 81. The second rack 21 is fixedly connected to the second panel 82. The second gear 19 meshes with the second rack 21, driving the first rack 20 to move. The movement of the rack 21 (driven by the second motor 27 to rotate the second gear 19) causes the second panel 82 to move. When both the first air vent 1 and the second air vent 2 move from the closed state to the open state, the first panel 81 and the second panel 82 move in opposite directions until at least a partial overlap exists between them, and the overlapping area is the first overlapping area. When both the first air vent 1 and the second air vent 2 move from the open state to the closed state, the first panel 81 and the second panel 82 move in opposite directions until they do not overlap or a second overlapping area exists, and the second overlapping area is smaller than the first overlapping area.

[0045] This is a preferred driving method for the first panel and the second panel of the present invention. The first panel can be driven to translate by the first gear and the first rack, and the second panel can be driven to translate by the second gear and the second rack. The first panel and the second panel move in opposite directions, thereby opening the first air vent, opening the second air vent, and independently controlling the closing of the first air vent and the closing of the second air vent. The first panel and the second panel can overlap in part, thereby ensuring that the first air vent and the second air vent can be opened effectively, while reducing the space occupied and making the structure more compact.

[0046] In some implementations... The first magnetic attraction device includes an upper magnetic attraction device 22 disposed on the first panel 81 and an upper magnetic attraction device 23 disposed on the housing 3 at the first air vent 1. When the first air vent 1 is opened and the first filter 16 needs to move to the first air vent 1, the upper magnetic attraction device 23 is energized to magnetically attract the first filter 16 to the first air vent 1. When the first air vent 1 is opened and the first filter 16 does not need to move to the first air vent 1, the upper magnetic attraction device 22 is energized to magnetically attract the first filter 16 to the interior of the first panel 81 and away from the first air vent 1. The second magnetic attraction device includes a lower magnetic attraction device 24 disposed on the second panel 82 and a lower magnetic attraction device 25 disposed on the housing 3 at the second air vent 2. When the second air vent 2 is opened and the second filter 17 needs to move to the second air vent 2, the lower magnetic attraction device 25 is energized to magnetically attract the second filter 17 to the second air vent 2. When the second air vent 2 is opened and the second filter 17 does not need to move to the second air vent 2, the lower magnetic attraction device 24 is energized to magnetically attract the second filter 17 to the interior of the second panel 82 and away from the second air vent 2.

[0047] This is a preferred structural form of the first and second magnetic attraction devices of the present invention. The first magnetic attraction device includes two upper magnetic attraction devices, one located on the first panel and the other on the housing (panel body). When air is introduced through the upper air vent or when air is discharged without a draft, the first filter element is attracted to the housing by energizing the second upper magnetic attraction device (while the first upper magnetic attraction device is not energized), thus blocking the first air vent and achieving the effects of air filtration and air discharge without a draft. When air is discharged with a draft through the upper air vent, the first filter element is attracted to the first panel without blocking the first air vent by energizing the first upper magnetic attraction device (while the second upper magnetic attraction device is not energized), thus achieving the effect of air discharge with a draft. Similarly, the second magnetic attraction device includes two upper magnetic attraction devices, one lower magnetic attraction device located on the second panel and the other on the housing (panel body). When air is drawn in through the downwind vent or when no wind is felt during airflow, the second filter is attracted to the housing by energizing the second lower magnetic device (while the first lower magnetic device is de-energized), thus blocking the second air vent and achieving both air intake filtration and no wind at the air outlet. When airflow is felt through the downwind vent, the second filter is attracted to the second panel by energizing the first lower magnetic device (while the second lower magnetic device is de-energized), without blocking the second air vent, thus achieving a wind-felt airflow effect. This allows for multiple airflow effects, including air intake filtration, no wind at the air outlet, and wind-felt airflow, meeting diverse user needs and improving user comfort.

[0048] In some implementations... In the longitudinal section, the first air duct 4 includes a first air duct wall 41 and a second air duct wall 42 opposite to each other, the second air duct 5 includes a third air duct wall 51 and a fourth air duct wall 52 opposite to each other, one end of the first heat exchange section 11 that is relatively far away from the second heat exchange section 12 is connected to the third air duct wall 51, one end of the second heat exchange section 12 that is relatively close to the first heat exchange section 11 is connected to the first air duct wall 41, one end of the partition 7 is connected to the fourth air duct wall 52, and the other end of the partition 7 is connected to the second air duct wall 42.

[0049] This is a preferred structural form of the first and second air ducts of this utility model, as well as a preferred structural form in which the multiple heat exchange sections are sealed to the walls of the multiple air ducts respectively. This further ensures the sealing between the multiple heat exchangers and the multiple air ducts, thereby further reducing the situation where heat is discharged to the air outlet without heat exchange by the heat exchanger, further improving the heat exchange capacity of the indoor unit of the air conditioner, improving the heating and cooling performance, and improving the energy efficiency of the system.

[0050] In some implementations... It also includes a first fan blade 14 (preferably a cross-flow fan blade) and a second fan blade 15 (preferably a cross-flow fan blade), wherein at least a portion of the structure of the first fan blade 14 is disposed in the first air duct 4, and at least a portion of the structure of the second fan blade 15 is disposed in the second air duct 5. The first fan blade 14 and the second fan blade 15 are spaced apart and arranged opposite to each other, and at least a portion of the structure of the heat exchanger 10 is also located in the space between the first fan blade 14 and the second fan blade 15. In the top air outlet mode, the first fan blade 14 rotates while the second fan blade 15 does not rotate. In the downward air outlet mode, the second fan blade 15 rotates while the first fan blade 14 does not rotate. In the up-and-down air outlet mode, both the first fan blade 14 and the second fan blade 15 rotate.

[0051] This invention, through the first and second fan blades respectively installed in the first and second air ducts, can generate the driving force for airflow. In particular, in normal cooling mode, it can select the top air outlet mode, where only the rotation of the first fan blade achieves top air outlet of the first air vent, while the second and third air vents both receive air. In normal heating mode, it can select the bottom air outlet mode, where only the rotation of the second fan blade achieves top air outlet of the second air vent, while the first and third air vents both receive air. In rapid cooling or rapid heating mode, it can select the top and bottom air outlet mode, where both fan blades operate, achieving air outlet of both the first and second air vents, realizing rapid cooling or heating of the room. At this time, the third air vent receives air, increasing the air intake volume, improving cooling and heating capacity, and improving energy efficiency (increasing the air intake volume can be achieved without adding more fans).

[0052] This invention can achieve mode switching control simply by using two fans, solving the problem that the existing technology requires multiple motors and dampers to drive and control the airflow through the heat exchanger and achieve airflow at the top and bottom, resulting in complex control and high cost.

[0053] This utility model also provides an air conditioner, which includes the aforementioned reversible air outlet indoor unit.

[0054] This utility model provides a reversible air outlet dual-duct air conditioner. Through the dual-duct dual-flow fan blade design, the heat exchanger completely covers the air inlet of the duct, so that the airflow is all heated by the heat exchanger and then blown into the room through the corresponding air duct, which can realize different air outlet modes.

[0055] The improvements of this utility model are as follows: 1. A dual cross-flow fan blade and dual air ducts are designed within a single housing; the heat exchanger is designed with a large bend between the two air ducts and covers the air inlets of the two air ducts respectively, ensuring that the airflow is heated by the heat exchanger and then blown into the room through the corresponding air duct.

[0056] 2. The upper and lower panels, along with the matching gear and rack drive structure, work together to open and close the upper and lower air inlets and outlets, thus reducing gaps and improving the aesthetics of the appearance.

[0057] 3. The upper and lower filter screen assemblies are designed inside the panel. Guide grooves are designed on both sides of the panel and coated with silicone grease. The filter screen assemblies are designed in a circular shape on both sides and installed in the guide grooves of the panel to reduce the friction between the filter screen assemblies and the panel and make the operation smoother.

[0058] 4. Magnetic suction devices are designed on both sides of the filter assembly along its length. Magnetic suction devices are also designed at corresponding positions on the upper and lower air outlet panels, forming four sets of magnetic suction devices. When the magnetic suction devices are powered on, the two magnetic blocks attract each other; when the power is off, the two magnetic blocks no longer attract each other. This design allows the filter to extend and retract.

[0059] 5. The filter assembly at the air inlet filters the air, keeping it clean and reducing dust accumulation on the evaporator components, thus improving cooling and heating efficiency. At the air outlet, the filter assembly acts as a draft-free system, dispersing the airflow. Users can choose to turn the draft-free function on or off as needed, improving comfort.

[0060] 6. The air conditioner can provide shower-like airflow for cooling and carpet-like airflow for heating, and can also add a windless function.

[0061] 7. The air conditioner has two air inlets and two cross-flow fan blades, which greatly increases the air circulation volume and improves the cooling and heating effect.

[0062] This utility model features a filter assembly, a panel, and a magnetic attraction device on the panel. When the magnetic attraction device is powered on, the two magnetic blocks attract each other; when the power is off, the two magnetic blocks no longer attract each other. This design allows the filter to extend and retract. Figure 1 .

[0063] Implementation method: When the air conditioner is off, the top and bottom panels are extended, and the filter assembly is retracted into the inner surface of the panels. Figure 2 .

[0064] In cooling mode, when the air conditioner is turned on, the lower magnetic suction device 25 is energized, and the long side of the lower filter is attached to the housing 3 (panel). The second motor 27 starts working, driving the lower panel gear to rotate counterclockwise, moving the lower panel upward and opening the lower air vent. At this time, the filter remains in place due to the magnetic attraction, filtering the air. If the user selects to activate the no-wind-sensor function, the upper magnetic suction device 23 is energized, and the long side of the upper filter is attached to the housing 3 (panel). The first motor 26 starts working, driving the upper panel gear to rotate clockwise, moving the upper panel downward. At this time, the filter remains in place due to the magnetic attraction, dispersing the airflow. If the user does not select to activate the no-wind-sensor function, the upper magnetic suction device 23 is not energized, and the upper magnetic suction device 22 is energized. The filter is attached to the first panel, and the first motor 26 starts working, driving the upper panel gear to rotate clockwise, moving the upper panel downward. At this time, the filter moves downward with the panel, opening the upper air vent. Figure 3-4 .

[0065] In heating mode, when the air conditioner is turned on, the upper magnetic suction device 23 is energized, and the long side of the upper filter is attached to the housing 3 (panel). The first motor 26 starts working, driving the upper panel gear to rotate clockwise, moving the upper panel downwards and opening the upper air vent. At this time, the filter remains in place due to the magnetic attraction, filtering the air. If the user selects to activate the no-wind-feed function, the lower magnetic suction device 25 is energized, and the long side of the lower filter is attached to the panel. The second motor 27 starts working, driving the lower panel gear to rotate counterclockwise, moving the lower panel upwards. At this time, the filter remains in place due to the magnetic attraction, dispersing the airflow. If the user does not select to activate the no-wind-feed function, the lower magnetic suction device 25 is not energized, and the lower magnetic suction device 24 is energized. The filter is attached to the panel, and the second motor 27 starts working, driving the lower panel gear to rotate counterclockwise, moving the lower panel upwards. At this time, the filter moves upwards with the panel, opening the lower air vent for airflow. Figure 5-6 .

[0066] In the air conditioner's top and bottom airflow mode (which can be used for either cooling or heating, achieving rapid heat exchange), if the windless mode is activated, both the upper magnetic device 23 and the lower magnetic device 25 are powered, while the upper magnetic device 1 22 and the lower magnetic device 1 24 are de-energized; if the wind-sensing mode is activated, both the upper magnetic device 1 22 and the lower magnetic device 1 24 are powered, while the upper magnetic device 23 and the lower magnetic device 25 are de-energized. Figure 7-8 .
