Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning indoor unit, an air conditioner having the same, and an air conditioner control method. Background Art

[0002] In modern living and working environments, air conditioning systems have become indispensable equipment, especially in residential or office spaces, where the function of regulating indoor temperature and humidity is particularly important. However, the limitations of traditional wall-mounted air conditioning units in wind field control and air outlet mode often affect their use effect and user comfort experience. Specifically, the air outlet mode of traditional wall-mounted air conditioners is single, usually delivering hot and cold air through a lower air outlet.

[0003] However, in actual use, this single air outlet design has obvious disadvantages. In heating mode, due to the natural buoyancy of hot air, even if the wind deflector adjusts the wind direction to the lowest angle, the hot air often begins to float up before the lower space of the room is fully heated, resulting in a slow rise in temperature near the ground. Users feel insufficient warmth at their feet, especially in cold winter, when this temperature difference is more obvious. In cooling mode, cold air blows out from the same air outlet. Although the wind deflector can adjust the wind direction, users may feel uncomfortable when the cold air blows directly on the human body, especially for the elderly and children. Long-term direct blowing of cold air can easily cause health problems. In addition, the cold air begins to sink before fully covering the entire room, which can also cause uneven temperature distribution in the room. Summary of the invention

[0044] According to another aspect of the present invention, there is provided an air conditioner control method, which is applicable to any of the above-mentioned air conditioner indoor units, and the air conditioner control method comprises:

[0045] Responsive to user needs;

[0046] When it is determined that cooling is required, the first switching plate is controlled to be in the first position so that the upper air outlet is in an open state, and the second switching plate is controlled to be in the second position so that the lower air outlet is in a closed state, so that the air-conditioning indoor unit is in an upper air outlet mode; or, the first switching plate is controlled to be in the first position and the second switching plate is in the fourth position so that the upper air outlet and the lower air outlet are both in an open state, so that the air-conditioning indoor unit is in a simultaneous upper and lower air outlet mode.

[0048] By applying the technical solution of the present invention, the indoor unit of the air conditioner of the present application can significantly improve the air circulation efficiency and achieve a more balanced indoor temperature distribution by providing a first air inlet on the first side wall of the mounting shell and a second air inlet on the second side wall.

In the lower air outlet mode, the hot air is directly blown from the lower air outlet to the ground, realizing carpet-style heating to ensure the warmth of the feet. At the same time, the hot air gradually rises from the ground, improving the overall heating efficiency. In the upper and lower simultaneous air outlet mode, the upper and lower air outlets are enabled at the same time, which is suitable for situations where rapid cooling or heating is required to ensure that the indoor temperature quickly reaches the user's set value.

[0050] The introduction of the fan can effectively enhance the air intake and delivery capabilities, and cooperate with the switching structure to achieve precise control of the wind direction. The position adjustment of the first switching plate and the second switching plate can not only control the opening and closing of the upper and lower air outlets, but also adjust the air volume to meet the needs of different seasons and environments. This design not only reduces energy consumption, but also increases the speed of cooling and heating, allowing users to feel obvious temperature changes in a short time, greatly improving the user experience and comfort. At the same time, since the wind direction can be flexibly controlled through the switching structure, the problem of uneven air supply in traditional air conditioners is avoided, thereby reducing the temperature stratification in the room, achieving a more balanced temperature distribution, and further improving the heat exchange efficiency and energy-saving effect of the air conditioner.

[0061] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0062] In modern living and working environments, air conditioning systems have become indispensable equipment, especially in residential or office spaces, where the function of regulating indoor temperature and humidity is particularly important. However, the limitations of traditional wall-mounted air conditioning units in wind field control and air outlet mode often affect their use effect and user comfort experience. Specifically, the air outlet mode of traditional wall-mounted air conditioners is single, usually delivering hot and cold air through a lower air outlet.

[0063] However, in actual use, this single air outlet design has obvious disadvantages. In heating mode, due to the natural buoyancy of hot air, even if the wind deflector adjusts the wind direction to the lowest angle, the hot air often begins to float up before the lower space of the room is fully heated, resulting in a slow rise in temperature near the ground. Users feel insufficient warmth at their feet, especially in cold winter, when this temperature difference is more obvious. In cooling mode, cold air blows out from the same air outlet. Although the wind deflector can adjust the wind direction, users may feel uncomfortable when the cold air blows directly on the human body, especially for the elderly and children. Long-term direct blowing of cold air can easily cause health problems. In addition, the cold air begins to sink before fully covering the entire room, which can also cause uneven temperature distribution in the room.

[0064] The technical purpose of the present application is to provide an air-conditioning indoor unit, an air conditioner having the same, and an air-conditioner control method, so as to solve the problem that the air-conditioning indoor unit in the prior art has only a single air outlet mode, resulting in uneven distribution of hot air or cold air in the room, thereby causing poor customer experience.

[0065] First, the present application provides an air conditioner indoor unit, including an installation shell 10, wherein an installation cavity is provided in the installation shell 10, a first air inlet 20 communicating with the installation cavity is provided on a first side wall of the installation shell 10, a second air inlet 30 communicating with the installation cavity is further provided on a second side wall of the installation shell 10, and an upper air outlet 40 and a lower air outlet 50 are further provided on a third side wall of the installation shell 10;

[0066] The switching structure 70 includes a first switching plate 701 movably arranged at the upper air outlet 40, so as to open or close the upper air outlet 40 through the first switching plate 701. The switching structure 70 also includes a second switching plate 702 movably arranged at the lower air outlet 50, so as to open or close the lower air outlet 50 through the second switching plate 702. The switching structure 70 enables the air conditioner indoor unit to switch between multiple air outlet modes, and the multiple air outlet modes include an upper air outlet mode, a lower air outlet mode and a simultaneous upper and lower air outlet mode.

[0067] Specifically, Figures 1 to 7 As shown, the air conditioner indoor unit provided in the present application includes a mounting shell 10, and a first air inlet 20 is arranged on a first side wall of the mounting shell 10 (a side close to the wall when installed), and there are two first air inlets 20, and the two first air inlets 20 are arranged along the length direction of the mounting shell 10, and each first air inlet 20 is composed of a plurality of ventilation grilles. Second air inlets 30 are also arranged on two second side walls of the mounting shell 10, and the second side walls are two side walls arranged along the length direction of the mounting shell 10, and each second air inlet 30 is composed of a plurality of ventilation grilles, as shown in FIG. Figure 2As shown, an upper air outlet 40 and a lower air outlet 50 are further provided on the third side wall of the mounting shell 10, and the third side wall is the front side wall of the mounting shell 10. The upper air outlet 40 and the lower air outlet 50 are both arranged on the opposite side of the position of the first air inlet 20. A fan 60 is further provided in the mounting cavity for introducing external wind into the mounting cavity and sending wind out from the upper air outlet 40 and the lower air outlet 50. A switching structure 70 is further provided in the mounting cavity. The switching structure 70 includes a first switching plate 701, which is arranged at the upper air outlet 40. The switching structure 70 also includes a second switching plate 702 arranged at the lower air outlet 50. By controlling the first switching plate The position of 701 can adjust the size of the upper air outlet 40. By controlling the position of the second switching plate 702, the size of the lower air outlet 50 can be adjusted. The air outlet mode of the air-conditioning indoor unit can also be controlled by controlling the positions of the first switching plate 701 and the second switching plate 702, including an upper air outlet mode. The upper air outlet mode is when the lower air outlet 50 is in a closed state and the upper air outlet 40 is in an open state. The air outlet mode also includes a lower air outlet mode. The lower air outlet mode is when the lower air outlet 50 is in an open state and the upper air outlet 40 is in a closed state. The air outlet mode also includes an upper and lower simultaneous air outlet mode. The upper and lower simultaneous air outlet mode is when the upper air outlet 40 and the lower air outlet 50 are both in an open state.

[0068] The air conditioner indoor unit of the present application can significantly improve the air circulation efficiency and achieve a more balanced indoor temperature distribution by providing a first air inlet 20 on the first side wall of the mounting housing 10 and a second air inlet 30 on the second side wall. Specifically, the two first air inlets 20 are located on the wall side of the mounting housing 10, which is conducive to directly sucking air from the bottom and higher areas of the room, thereby avoiding the problem of poor air flow caused by hot air floating up or cold air sinking in certain seasons or environments. The second air inlets 30 are located on both sides, further enhancing the multi-directional inflow of air and ensuring comprehensive coverage and circulation of air.

[0069] An upper air outlet 40 and a lower air outlet 50 are provided on the third side wall of the mounting shell 10. Such a design can flexibly adjust the wind direction and air volume according to the cooling or heating requirements. In the upper air outlet mode, the cold air is evenly blown from the upper air outlet 40 to the top of the room, forming a shower-like cooling effect, avoiding the cold air from blowing directly to the human body, and improving the user's comfort. In the lower air outlet mode, the hot air is directly blown from the lower air outlet 50 to the ground, realizing carpet-style heating, ensuring the warmth of the feet, and at the same time the hot air gradually rises from the ground, improving the overall heating efficiency. In the upper and lower simultaneous air outlet mode, the upper air outlet 40 and the lower air outlet 50 are enabled at the same time, which is suitable for situations where rapid cooling or heating is required to ensure that the indoor temperature quickly reaches the user-set value.

[0070] The introduction of the fan 60 can effectively enhance the air intake and delivery capabilities, and cooperate with the switching structure 70 to achieve precise control of the wind direction. The position adjustment of the first switching plate 701 and the second switching plate 702 can not only control the opening and closing of the upper and lower air outlets, but also adjust the air volume to meet the needs of different seasons and environments. This design not only reduces energy consumption, but also increases the speed of cooling and heating, allowing users to feel obvious temperature changes in a short time, greatly improving the user experience and comfort. At the same time, since the wind direction can be flexibly controlled by the switching structure 70, the problem of uneven air supply in traditional air conditioners is avoided, thereby reducing the temperature stratification in the room, achieving a more balanced temperature distribution, and further improving the heat exchange efficiency and energy-saving effect of the air conditioner.

[0071] Further, the first side wall is a rear side wall of the mounting housing 10, the third side wall is a front side wall of the mounting housing 10, and the first side wall and the third side wall are arranged opposite to each other; and / or,

[0072] The second side walls are two side walls of the mounting housing 10 along its extending direction.

[0073] The first air inlet 20 of the rear side wall can directly inhale the air near the wall, which is often difficult to effectively use in traditional air conditioners due to the limitation of air supply direction. Through this convection design, indoor air can exchange heat with the air conditioner more quickly, improving the cooling or heating efficiency of the air conditioner.

[0074] The first air inlet 20 of the rear side wall is combined with the two air outlets of the front side wall to prevent the cold and hot air flows from flowing back to the air inlet after being sent out, reducing the local temperature difference and making the indoor temperature distribution more uniform. In particular, in the cooling mode, the cold air is sent out from the top and bottom, which can quickly reduce the overall indoor temperature, while in the heating mode, the hot air is sent out from the bottom, ensuring that the temperature of the ground area is raised and then gradually diffused to the entire room, avoiding the discomfort of "hot head and cold feet".

[0075] Furthermore, the air conditioner indoor unit also includes: a driving structure, which is arranged in the installation cavity, and the driving structure is respectively connected to the first switching plate 701 and the second switching plate 702 to control the air conditioner indoor unit to switch between multiple air outlet modes.

[0076] Specifically, the air-conditioning indoor unit also includes a driving structure arranged in the installation cavity, and the driving structure is respectively driven and connected to the first switching plate 701 and the second switching plate 702, so as to control the positions of the first switching plate 701 and the second switching plate 702 in the installation cavity, thereby enabling the air-conditioning indoor unit to switch between multiple air outlet modes.

[0077] The drive structure can accurately control the positions of the first switching plate 701 and the second switching plate 702, which means that the user can quickly switch from one air outlet mode to another, such as switching from the upper air outlet mode to the lower air outlet mode, or directly switching to the upper and lower air outlet mode. This flexibility enables the air conditioner to instantly adjust the air supply strategy according to the ambient temperature and user needs to improve comfort.

[0078] By controlling the position change of the switching plate through the driving structure, compared with the frequent physical rotation of traditional mechanical air guide plates, the design of this application reduces the direct friction and wear of mechanical parts, extends the life of the air conditioner indoor unit, and reduces maintenance costs.

[0079] The drive structure can adjust the size and direction of the air outlet according to actual needs, avoiding unnecessary waste of air volume. For example, in the shower cooling mode, only the upper air outlet 40 is required to work, and in the carpet heating mode, only the lower air outlet 50 is required to work, which reduces the energy consumption of the air conditioner during operation and achieves a higher energy efficiency ratio.

[0080] Users can easily select different air outlet modes through the remote control or smart device, without having to manually adjust the air guide plate, making operation more convenient. At the same time, because the drive structure can accurately control the wind direction and air volume, it avoids the discomfort of cold air blowing directly on the human body or hot air not reaching the ground, allowing users to enjoy a comfortable temperature environment in different seasons and usage scenarios.

[0081] Compared with mechanical adjustment, the adoption of a drive structure can often reduce the noise caused by air duct switching, especially when the position of the switching plate is adjusted, it can be smoother and quieter, creating a quieter use environment for users.

[0082] Due to the compact design of the drive structure, it can be effectively embedded in the installation cavity of the air conditioner indoor unit without taking up additional indoor space, thus maintaining the simple and beautiful appearance of the air conditioner. At the same time, it may also provide more layout space for other components of the indoor unit, thereby optimizing the overall design.

[0083] Furthermore, the driving structure includes:

[0084] The first driving component is disposed on the mounting housing 10 , and a driving end of the first driving component is drivingly connected to the first switching plate 701 through the first transmission structure 80 to drive the first switching plate 701 to adjust the size of the upper air outlet 40 .

[0085] Further, the first transmission structure 80 includes:

[0086] An upper driving gear 801, the upper driving gear 801 is drivingly connected to the driving end of the first driving component;

[0087] The upper driven gear 802 is movably disposed on the inner side wall of the mounting housing 10, and a side of the upper driven gear 802 away from the inner side wall of the mounting housing 10 is connected to the first switching plate 701;

[0088] The upper driving gear 801 is meshedly connected with the upper driven gear 802 , so that the first switching plate 701 is driven by the first driving component to rotate around the axis of the upper driven gear 802 to adjust the size of the upper air outlet 40 .

[0089] Specifically, the driving structure includes a first driving component arranged on the mounting housing 10, such as Figure 7 As shown, the driving end of the first driving component is connected to the first switching plate 701 through the first transmission structure 80, so as to adjust the position of the first switching plate 701, wherein the first driving component in this embodiment can be a driving motor, and the first transmission structure 80 includes an upper driving gear 801 drivingly connected to the driving end of the first driving component, the upper driving gear 801 is meshingly connected with an upper driven gear 802, and the upper driven gear 802 is movably mounted on the inner side wall of the mounting shell 10 through a third rotating shaft, and the side of the upper driven gear 802 away from the mounting shell 10 is connected to the first switching plate 701. When in use, the first driving component drives the upper driving gear 801 to rotate, and the upper driving gear 801 drives the upper driven gear 802 meshingly connected thereto to rotate, so that the upper driven gear 802 drives the first switching plate 701 to rotate, so as to switch the position of the first switching plate 701, thereby adjusting the size of the upper air outlet 40.

[0090] The combination of the drive motor and the gear transmission structure can realize smooth and fast movement of the first switching plate 701, thereby accurately adjusting the size of the upper air outlet 40. This high-precision control method not only has a fast response speed, but also avoids the air volume adjustment lag problem commonly seen in traditional manual or non-precision electric control, thereby improving the overall adjustment capability and efficiency of the air conditioning system.

[0091] Compared with the traditional adjustment method of direct contact or friction of moving parts, the gear transmission mechanism in this application runs more smoothly and produces less noise. When the air conditioner is running, the user will hardly notice the sound generated when the switch plate adjusts its position, creating a quieter use environment for the user.

[0092] By driving the motor to control the position of the first switching plate 701, the air volume and wind direction can be accurately adjusted according to the actual needs of the room, avoiding excessive consumption of air volume. Especially in the shower cooling or carpet heating mode, the air volume can be efficiently utilized, unnecessary air conditioning operation time can be reduced, and energy can be saved.

[0093] The gear transmission mechanism has high reliability, and its structural design can withstand long-term operation and frequent adjustments. The combination of drive motor and gear reduces direct wear of mechanical parts, thereby extending the service life of the entire air conditioner indoor unit and reducing maintenance and replacement costs.

[0094] The combined design of the drive motor and gear transmission structure makes the installation and maintenance of the drive structure relatively simple. The standardization of the drive motor and the modularization of the gear assembly facilitate integration on the production line, as well as troubleshooting and component replacement in the later stage.

[0095] The user can remotely control the operation of the drive motor through a smart device or a remote controller, thereby adjusting the position of the first switching plate 701 and the opening degree of the upper air outlet 40. This intelligent operation method improves the user's convenience and comfort, especially at night or when it is inconvenient to directly operate the air conditioner, the user can still easily adjust the air conditioner state.

[0096] Furthermore, the driving structure also includes:

[0097] The second driving component is disposed on the mounting shell 10 , and the driving end of the second driving component is transmission-connected to the second switching plate 702 via a second transmission structure to drive the second switching plate 702 to adjust the size of the lower air outlet 50 .

[0098] Furthermore, the second transmission structure includes:

[0099] A first rotating shaft, the first rotating shaft is rotatably disposed in the mounting housing 10, and a side edge of the second switching plate 702 along its length direction is fixedly connected to the first rotating shaft;

[0100] The driving end of the second driving component is drivingly connected to one end of the first rotating shaft, so as to drive the second switching plate 702 to move through the first rotating shaft, so as to adjust the size of the lower air outlet 50 .

[0101] Specifically, the driving structure also includes a second driving component disposed on the mounting housing 10. The second driving component is a driving motor in this embodiment. The driving end of the second driving component is connected to the second switching plate 702 through a second transmission structure. The second transmission structure includes a first rotating shaft rotatably disposed in the mounting housing 10. One side edge of the second switching plate 702 is fixedly connected to the first fixed shaft. Figure 4 As shown, the first rotating shaft is the supporting point of the movement trajectory of the second switching plate 702. During use, driven by the second driving component, the first rotating shaft is driven to rotate around its own axis, thereby driving the second switching plate 702 to rotate around the axis of the first rotating shaft, and then the size of the lower air outlet 50 is adjusted by the rotation of the second switching plate 702.

[0102] The second driving component is driven by a motor and can quickly adjust the position of the second switching plate 702, thereby realizing accurate control of the size of the lower air outlet 50. This high-precision, fast-response adjustment mechanism ensures that the air conditioner can make corresponding adjustments in real time according to user settings or environmental changes in different modes, thereby improving user experience and overall system flexibility.

[0103] The motor drive combined with the gear or shaft transmission mode makes the operation more stable, and the noise and vibration generated are significantly lower than the traditional mechanical adjustment method. When the air conditioner is running, the user will hardly notice the noise generated during the adjustment of the switch plate, creating a quieter and more comfortable use environment.

[0104] By precisely controlling the opening degree of the second switching plate 702 through the motor, the air volume can be adjusted according to the actual needs of the room, avoiding energy waste caused by inaccurate air volume control in traditional air conditioners. Especially in the carpet heating mode, precise air volume control can ensure that the hot air effectively reaches the ground, improving the overall heating efficiency.

[0105] The second transmission structure driven by the motor supports the movement of the second switching plate 702 through the first rotating shaft, thereby reducing direct friction and wear, improving the stability and durability of the long-term operation of the system, and reducing maintenance costs.

[0106] The modular design of the motor and drive shaft facilitates component replacement or upgrading during production and subsequent maintenance, simplifies the maintenance process, and ensures the long-term stable performance of the air-conditioning indoor unit.

[0107] Furthermore, the air conditioner indoor unit also includes:

[0108] The air adjustment structure includes a third switching plate 90 movably disposed on the lower side wall of the upper air outlet 40 , so as to adjust the air volume entering the upper air outlet 40 and the lower air outlet 50 by adjusting the position of the third switching plate 90 .

[0109] Furthermore, the air adjustment structure also includes:

[0110] The third driving component is disposed in the mounting housing 10 , and the driving end of the third driving component is transmission-connected to the third switching plate 90 through a third transmission structure to drive the third switching plate 90 to move.

[0111] Furthermore, the third transmission structure includes:

[0112] A second rotating shaft, the second rotating shaft is rotatably disposed in the mounting housing 10, and a side edge of the third switching plate 90 along its length direction is fixedly connected to the second rotating shaft;

[0113] Among them, the driving end of the third driving component is drivingly connected to one end of the second rotating shaft, so that under the drive of the third driving component, the third switching plate 90 is driven to rotate around the axis of the second rotating shaft, so that the free end of the third switching plate 90 is relatively close to or away from the fan 60, so as to adjust the air volume entering the upper air outlet 40 and the lower air outlet 50.

[0114] Specifically, Figure 2 , Figure 3 and Figure 4 As shown, the air conditioning indoor unit also includes an air conditioning structure arranged in the installation cavity, the air conditioning structure includes a third switching plate 90, and a third driving component and a third transmission structure for driving the third switching plate 90 to rotate. The third driving component is a driving motor in this embodiment, and the output end of the third driving component is connected to a second rotating shaft, and the extension direction of the second rotating shaft is consistent with the extension direction of the third switching plate 90. One side edge of the extended length direction of the third switching plate 90 is connected to the second rotating shaft, as shown in FIG. Figure 4 As shown, a second rotating shaft is provided at the end of the lower side wall of the upper air outlet 40 extending into the installation cavity, and the third switching plate 90 rotates around the axis of the second rotating shaft, so that the air output of the upper air outlet 40 and the lower air outlet 50 can be adjusted by controlling the position of the third switching plate 90.

[0115] The combination of the third driving component and the third transmission structure can accurately adjust the position of the third switching plate 90, thereby controlling the air volume of the upper air outlet 40 and the lower air outlet 50. This means that users can flexibly adjust the output of hot and cold air according to the size of the room, ambient temperature and personal preferences to achieve optimal comfort.

[0116] The use of a drive motor ensures that the third switching plate 90 has a quick rotation response, and can immediately adjust the air volume when user demand changes, thereby improving the dynamic adjustment capability of the air-conditioning indoor unit. This quick response is particularly important in scenarios where the room temperature needs to be changed quickly.

[0117] The motor drive method produces less noise than the traditional mechanical adjustment method, providing a quieter use environment. This is especially important for places where low noise is required, such as sleeping at night and in the office, ensuring that users will not be disturbed by additional noise while enjoying a comfortable temperature.

[0118] Through the precise control of the third switching board 90, the air conditioning system can dynamically adjust the air volume according to actual needs, avoiding unnecessary energy consumption. Especially in the shower cooling or carpet heating mode, this precise air volume adjustment can significantly improve the cooling or heating efficiency and reduce energy waste.

[0119] The use of drive motors and transmission structures reduces direct friction and mechanical wear, and improves the long-term operating stability and durability of the air conditioner indoor unit. At the same time, the modular design of motors and transmission structures facilitates component replacement or upgrading during production and post-maintenance, reducing maintenance costs.

[0120] Furthermore, the first switching board 701 includes:

[0121] The first subdivision 7011 is a straight board;

[0122] The second section 7012 is connected to the first section 7011 along the tangent direction of the outer peripheral surface of the fan 60 , and the second section 7012 is an arc-shaped plate.

[0123] Specifically, the first switching plate 701 includes a first section 7011 in the shape of a straight plate, and also includes a second section 7012 in the shape of an arc plate, wherein the second section 7012 is connected to the first section 7011 along the tangent direction of the outer peripheral surface of the fan 60, that is, one side edge of the second section 7012 along its length direction is connected to one side edge of the first section 7011 along its length direction.

[0124] The connection between the arc-shaped second section 7012 and the outer peripheral surface of the fan 60 in the tangential direction helps to guide and optimize the direction of the airflow, reduce the collision and turbulence of the airflow between the switching plate and the fan, and thus improve the stability and efficiency of the airflow. This design allows the cold and hot air to pass through the air duct more smoothly when the air conditioner is delivering air, thereby enhancing the air delivery effect of the air conditioner.

[0125] The arc-shaped design of the second section 7012 reduces wind resistance, reduces the operating load of the fan 60, and thus reduces energy consumption. This means that under the same air supply volume, the air conditioner can operate with lower energy consumption, improves energy utilization efficiency, and helps achieve the goal of green energy saving.

[0126] The segmented design of the first switching plate 701 can ensure that the cold air in the shower-style cooling mode covers the upper space of the room more evenly, while avoiding direct blowing on the human body, thereby improving comfort. In the heating mode, the hot air can be more effectively guided to the lower part of the room, achieving carpet-style heating, allowing the feet to quickly feel warm, and meeting the comfort needs of users in different seasons.

[0127] The combination of the straight plate-shaped first subsection 7011 and the curved plate-shaped second subsection 7012 not only optimizes the airflow distribution, but also enhances the overall structural stability of the first switching plate 701. This design reduces the deformation and vibration of the switching plate under the action of high-speed airflow and prolongs its service life.

[0128] By optimizing the airflow path, the impact between the airflow and the switching plate is reduced. At the same time, the second section 7012 of the arc plate can absorb part of the vibration generated by the airflow, thereby reducing the sound when the air conditioner is running, providing users with a quieter environment. This effect is particularly important when sleeping at night or working quietly.

[0129] The segmented design of the first switching board 701 makes its layout inside the air-conditioning indoor unit more flexible, which is conducive to optimizing the entire structural layout. It also brings convenience to installation and maintenance, and enhances the practicality and aesthetics of the design.

[0130] In shower-style cooling or carpet-style heating mode, the optimized design of the first switching plate 701 can more effectively achieve the temperature control target. The cold air evenly covers the top, and the hot air quickly sinks to the ground, which reduces the time required for the air conditioning system to reach the set temperature and improves the overall efficiency.

[0131] Further, the second switching board 702 includes:

[0132] The third sub-portion 7021 is movably disposed on the inner side of the lower side wall of the lower air outlet 50, and the third sub-portion 7021 is a straight plate;

[0133] The fourth section 7022 is a straight plate, and the fourth section 7022 is connected to the edge of the inner side of the lower side wall of the third section 7021 away from the lower air outlet 50;

[0134] The first angle between the third section 7021 and the fourth section 7022 is between 115° and 125°, and the first angle is arranged away from the front side wall of the mounting housing 10 .

[0135] Specifically, the second switching plate 702 includes a third sub-portion 7021, and the third sub-portion 7021 is arranged on the inner side of the lower side wall of the lower air outlet. Figure 2 As shown, the third division 7021 is in the shape of a straight plate, and also includes a fourth division 7022 in the shape of a straight plate, the fourth division 7022 is connected to the edge of the inner side of the lower side wall of the third division 7021 away from the lower air outlet 50, wherein a first angle set away from the front side wall of the mounting shell 10 is formed between the third division 7021 and the fourth division 7022, and the first angle is between 115° and 125°.

[0136] The straight-plate-shaped third subsection 7021 and the fourth subsection 7022, especially the first angle formed therebetween, are critical to the airflow guidance. The design of the first angle helps to more effectively guide the airflow to the floor of the room, achieving a carpet-like heating effect, ensuring a wider coverage of hot air and a more uniform temperature distribution, thereby improving heating efficiency and user comfort.

[0137] The specific angle range of the first angle (115° to 125°) optimizes the airflow path, reduces the resistance of the airflow at the second switching plate 702, and enables the fan 60 to drive the airflow more efficiently, thereby reducing energy consumption and improving the overall energy efficiency of the air-conditioning system.

[0138] The third section 7021 and the fourth section 7022 are connected by a first angle. This structural design increases the overall rigidity of the second switching plate 702, reduces deformation and vibration under airflow impact, and ensures the stability and durability of the switching plate during frequent use.

[0139] The design of the first angle optimizes the airflow path, reduces unnecessary turbulence and vibration, and thus reduces the noise generated when the air conditioner is running. This feature is particularly important, especially in places where a quiet environment is required, such as bedrooms, libraries or offices, which can provide users with a more peaceful experience.

[0140] The optimized design of the second switching plate 702 ensures that the hot air can be quickly and evenly distributed to the floor of the room in the heating mode, avoiding the common problem of hot air floating directly upward, so that users can enjoy a more comfortable and evenly warm environment in winter.

[0141] Further, the third switching board 90 includes:

[0142] The fifth subdivision 901 is movably disposed on the inner side of the lower side wall of the upper air outlet 40, and the fifth subdivision 901 is linear;

[0143] The sixth subsection 902 is linear and connected to the edge of the fifth subsection 901 away from the inner side of the lower side wall of the upper air outlet 40;

[0144] The second angle between the fifth sub-portion 901 and the sixth sub-portion 902 is between 170° and 180°, and the second angle is set away from the lower edge of the lower air outlet 50 .

[0145] Specifically, Figure 3 As shown, the third switching plate 90 includes a fifth division 901 movably arranged on the inner side of the lower side wall of the upper air outlet 40, and also includes a sixth division 902 in a straight line, and the sixth division 902 is arranged on the edge of the fifth division 901 away from the inner side of the lower side wall of the upper air outlet 40, wherein the second angle between the fifth division 901 and the sixth division 902 is between 170° and 180°, and the second angle is arranged away from the lower edge of the lower air outlet 50.

[0146] The coordinated design of the fifth subsection 901 and the sixth subsection 902 can more accurately control and guide the airflow. In particular, when the second angle between them is set between 170° and 180°, it can effectively prevent the airflow from forming eddies or turbulence between the switching plate and the air outlet, thereby improving the guiding property and control accuracy of the airflow and ensuring the optimization of the air supply effect.

[0147] This structural design optimizes the airflow path, reduces wind resistance, and reduces the motor power required by the air conditioner when delivering air, thereby reducing energy consumption. In particular, in cooling mode, cold air can pass through the upper air outlet 40 more smoothly, and in heating mode, hot air can sink to the ground more effectively, accelerating the equalization of indoor temperature and improving energy efficiency.

[0148] Through the precise control of the third switching plate 90, especially in the shower-type cooling and carpet-type heating modes, the hot and cold air can be more evenly distributed throughout the room, avoiding the discomfort of cold air blowing directly on the human body, while also ensuring the warmth of the feet, significantly improving the user's comfort experience.

[0149] The design of the fifth subsection 901 and the sixth subsection 902 not only optimizes the airflow path, but also increases the layout flexibility inside the air conditioner indoor unit. In particular, the design of the second angle enables the third switching plate 90 to fit tightly against the inner side of the lower side wall of the upper air outlet 40, thereby reducing the occupied space and optimizing the internal structure of the air conditioner.

[0150] By optimizing the airflow path and reducing the impact between the airflow and the switch plate, the design of the third switch plate 90 can effectively reduce the noise during the operation of the air conditioner. Especially at night or in occasions where a quiet environment is required, this design can provide users with a quieter use experience.

[0151] Furthermore, the air conditioner indoor unit also includes:

[0152] At least one support column 100, at least one support column 100 is arranged on the rear wall of the installation shell 10, each support column 100 extends along the height direction of the installation shell 10, and each support column 100 is arranged at intervals along the length direction of the installation shell 10. At least one support column 100 is provided with a mounting groove 101, so that the air conditioner indoor unit can be installed on the wall through the mounting groove 101.

[0153] Furthermore, the distance between one side of each support column 100 close to the wall and the first air inlet 20 along the width direction of the mounting housing 10 is 3 cm to 4 cm.

[0154] Specifically, Figure 1As shown, the air-conditioning indoor unit is still arranged on the support column 100 on the side of the installation shell 10 close to the wall. The number of the support columns 100 in this embodiment is 3, and the multiple support columns 100 are arranged in sequence along the length direction of the installation shell 10. The two first air inlets 20 are arranged between two adjacent support columns 100. All support columns 100 are protruding relative to the plane where the first air inlet 20 is located. A mounting groove 101 is respectively provided on each support column 100, and mounting protrusions are provided at positions of the wall corresponding to each mounting groove 101. By using the mounting protrusions and the mounting grooves 101 in coordination, the air-conditioning indoor unit can be installed on the wall. When the air-conditioning indoor unit is installed on the wall, the distance between the first air inlet 20 and the wall is 3 cm to 4 cm, that is, the distance between the side of each support column 100 close to the wall and the first air inlet 20 along the width direction of the installation shell 10 is 3 cm to 4 cm.

[0155] The design distance between each support column 100 and the first air inlet 20 is 3 cm to 4 cm, ensuring that air can enter the air conditioner indoor unit smoothly from the side and back. This design optimizes the air intake path, reduces air intake resistance, and improves air intake efficiency, which has a positive effect on the overall operating efficiency of the air conditioning system.

[0156] The protruding setting of the support column 100 relative to the plane where the first air inlet 20 is located effectively prevents the airflow from the air outlet from flowing back to the air inlet, reduces the probability of air short circuit, and thus reduces the problem of increased energy consumption and poor air conditioning effect caused by return air.

[0157] The three support columns 100 are arranged in sequence along the length direction of the mounting shell 10, which not only provides a stable mounting foundation, but also ensures the safe fixation of the air conditioner indoor unit on the wall through the cooperation between the mounting groove 101 and the mounting protrusion on the wall, avoiding safety hazards caused by unstable installation.

[0158] By providing a mounting groove 101 on the support column 100 and a corresponding mounting protrusion on the wall, the installation process of the air conditioner indoor unit is simplified, no complicated fixing devices or tools are required, the installation cost is reduced, and it is also convenient for users to install and maintain by themselves.

[0159] The layout design of the support column 100 not only considers functionality, but also takes into account aesthetics. This design allows the air conditioner indoor unit to better integrate into the indoor environment after installation. At the same time, the precise 3 cm to 4 cm distance between the support column 100 and the first air inlet 20 fully utilizes the space, reduces the occupation of indoor space, and improves the overall space utilization efficiency.

First, the user's needs must be obtained. When cooling is required, the first switching plate 701 is controlled to be in the first position, such as Figure 4 and Figure 5 As stated, Figure 4 FIG. 7 shows the movement trajectories of the first switching plate 701, the second switching plate 702 and the third switching plate 90. Figure 5 7. When the first switching plate 701 is in the first position and the second switching plate 702 is in the second position, the upper air outlet 40 is in the open state and the lower air outlet 50 is in the closed state, so that the indoor unit of the air conditioner is in the upper air outlet mode, or Figure 6 As shown, the first switching plate 701 is controlled to be in the first position, and the second switching plate 702 is controlled to be in the fourth position, so that the upper air outlet 40 and the lower air outlet 50 are both in the open state, so that the air conditioner indoor unit is in the upper and lower simultaneous air outlet mode; when it is determined that heating is required, as shown in FIG. Figure 6 As shown, the first switching plate 701 is controlled to be in the first position, and the second switching plate 702 is controlled to be in the fourth position, so that the upper air outlet 40 and the lower air outlet 50 are in the open state at the same time, so that the air conditioner indoor unit is in the upper and lower air outlet state at the same time;

[0167] When the various air outlet modes are in operation, the position of the third switching plate 90 can be adjusted at any time according to the air volume required by the user to control the air volume discharged from the upper air outlet 40 and the lower air outlet 50 .

[0168] This control method can intelligently adjust the working mode of the air-conditioning indoor unit according to the real-time needs of the user. Whether it is cooling, heating or simultaneous up and down air outlets, it can respond quickly and provide personalized temperature adjustment solutions, thereby improving the user experience.

[0169] By controlling the working states of the first switching plate 701, the second switching plate 702 and the third switching plate 90, the control method of the present application optimizes the airflow path, reduces unnecessary wind resistance, and enables the air-conditioning system to operate with lower energy consumption during cooling or heating, thereby improving energy utilization efficiency.

[0170] The position adjustment of the third switching plate 90 can accurately control the amount of air blown out from the upper air outlet 40 and the lower air outlet 50. The user can flexibly adjust the air volume according to the room size, personal preference or environmental changes, ensuring the accuracy and comfort of temperature regulation.

[0171] The coordinated use of the first switching board 701 and the second switching board 702 ensures the stability under different air outlet modes, avoids system abnormalities or failures caused by improper air duct switching, and extends the service life of the air conditioner.

[0172] Users can remotely control the working mode and air volume of the air conditioner through smart devices or remote controls without manual adjustment, making operation more convenient, especially in large spaces or multi-user scenarios, and can quickly meet the temperature requirements of different locations or individuals.

[0173] Whether it is a high temperature summer environment that requires rapid cooling, or a cold winter environment that requires lasting warmth, the control method of the present application can provide temperature adjustment solutions that adapt to different scenarios through flexible air duct switching and air volume adjustment, meeting diverse life and work needs.
