Description

Technical Field

[0001] This application relates to the field of energy-saving air conditioning technology, and more specifically, to an air conditioner and a control method. Background Technology

[0002] As a crucial household appliance for regulating indoor temperature and humidity, air conditioners directly impact indoor airflow distribution and user comfort through their air delivery method. Existing reversible air conditioners typically employ a cross-flow duct system, consisting of an upper and lower air outlet volute, each equipped with an independent movement mechanism to control the airflow path. Through coordinated movement, the air conditioner can switch the internal airflow direction, transitioning between "top intake, bottom exhaust" and "bottom intake, top exhaust" modes. This design is primarily based on fluid mechanics principles, aiming to align with the physical laws of cold air sinking and hot air rising: in cooling mode, bottom intake and top exhaust utilize the sinking characteristic of cold air; in heating mode, top intake and bottom exhaust utilize the rising characteristic of hot air, achieving faster temperature regulation efficiency.

[0003] However, in the existing technology, when using the top-discharge mode for cooling, the cold air from wall-mounted air conditioners, which are usually installed at a high position, can easily cause the ceiling surface temperature to drop too low, leading to condensation, dripping water, or even mold. At the same time, the cold air mixes with the surrounding air during its ascent, resulting in some energy loss. Secondly, in cooling mode, the evaporator is usually located upstream or in a specific position in the air duct. When using the top-discharge mode, the airflow path resistance is large, resulting in insufficient actual cooling air volume. Furthermore, since the air outlet is located at the top, the airflow cannot directly cover the area where people are active, resulting in slow cooling speed and poor user experience. Summary of the Invention

[0004] The main objective of this invention is to provide an air conditioner and control method to solve the problems in the prior art where the air conditioner is prone to condensation and mold growth on the ceiling and insufficient airflow when the air is vented from the top during cooling, and poor air intake and unstable airflow when the air is vented from the bottom during heating, thereby helping to reduce the energy consumption of the air conditioner.

[0005] To achieve the above objectives, according to one aspect of the present invention, an air conditioner is provided, comprising:

[0006] The housing has a top wall and a bottom wall disposed opposite to each other, and a side wall disposed between the top wall and the bottom wall;

[0007] The windward, side, and leeward openings are interconnected. The windward opening is located on the top wall, the side opening is located on the side wall, and the leeward opening is located on the bottom wall.

[0008] A windbreak structure is movably disposed within the housing to open or close at least one of the upper air vent and the side air vent;

[0009] Specifically, when the air conditioner is in cooling mode, the wind deflector moves to the first position so that the side air vents are open and the top air vents are closed. When the air conditioner is in heating mode, the wind deflector moves to the second position so that both the side air vents and the top air vents are open.

[0010] Furthermore, air conditioners also include:

[0011] A temperature sensing element is installed on the housing to detect the real-time temperature inside the room;

[0012] The first air guide structure is located at the side air outlet and is electrically / communicationally connected to the temperature detection element.

[0013] The first air guide structure is rotatably configured to adjust the first rotation angle of the first air guide structure relative to the side wall according to the real-time temperature, so as to adjust the flow direction of the airflow from the side air outlet.

[0014] Furthermore, air conditioners also include:

[0015] The second air guide structure is located at the downwind outlet and is electrically / communicationally connected to the temperature detection element.

[0016] The second air guide structure is rotatably configured to adjust the second rotation angle of the second air guide structure relative to the bottom wall according to the real-time temperature, so as to adjust the flow direction of the airflow coming out of the downwind outlet.

[0017] Furthermore, the first air guiding structure includes:

[0018] The first support component is rotatably disposed at the side air vent. The first support component is provided with a first communication hole for communicating the cavity of the housing with the outside, so that the direction of the airflow from the side air vent can be adjusted by adjusting the position of the first support component.

[0019] A first filter element is disposed on a first support element, and the first filter element has a first filter hole that communicates with a first connecting hole.

[0020] Furthermore, the first air guide structure also includes:

[0021] A first driving element is disposed on the housing, and the driving end of the first driving element is connected to the first support component in a transmission connection so as to drive the first support component to rotate.

[0022] The controller is electrically / communically connected to both the temperature sensor and the first drive element to adjust the first rotation angle between the first support member and the sidewall based on the detection result of the temperature sensor.

[0023] Furthermore, the air conditioner also includes a third air guide structure located at the upper air vent, the third air guide structure comprising:

[0024] The second support component is located at the upwind vent, and the second support component is provided with a second communication hole for connecting the cavity of the housing with the outside.

[0025] The second filter component is disposed on the second support component, and the second filter component has a second filter hole that communicates with the second connecting hole.

[0026] Furthermore, the air conditioner also includes a fan assembly disposed within the housing to introduce airflow into the air conditioner;

[0027] The windbreak structure includes a windbreak panel component movably disposed on the housing, the windbreak panel component being disposed around the fan assembly, so as to open or close at least one of the upper air vent and the side air vent by adjusting the position of the windbreak panel component.

[0028] Furthermore, the windbreak structure also includes:

[0029] A rotating component is disposed inside the housing and extends along a first direction; a wind baffle component is disposed on the rotating component.

[0030] A drive assembly is disposed within the housing. The drive end of the drive assembly is connected to a rotating component to drive the rotating component to rotate about a first direction, thereby causing the wind deflector component to rotate between the upper air vent and the side air vent, so as to open or close at least one of the upper air vent and the side air vent.

[0031] Furthermore, the driving components include:

[0032] The second driving element is disposed inside the housing. The driving end of the second driving element is provided with a first engaging member, and the rotating part is provided with a second engaging member.

[0033] The transmission components are respectively disposed on the first meshing member and the second meshing member, and mesh with the first meshing member and the second meshing member respectively, so that when the second driving element drives the first meshing member to rotate, the power is transmitted to the second meshing member through the transmission components, so that the rotating component is driven to rotate through the second meshing member.

[0034] According to another aspect of the present invention, a control method is provided, which is applied to the above-described air conditioner, the control method comprising:

[0035] When the air conditioner is in cooling mode, control the movement of the air deflector structure of the air conditioner so that the side air vents of the air conditioner are open and the top air vents are closed.

[0036] When the air conditioner is in heating mode, control the movement of the air deflector structure so that both the side air vents and the top air vents are open.

[0037] Furthermore, when the air conditioner is in cooling mode, the control method also includes:

[0038] Obtain the first real-time indoor temperature;

[0039] When the first real-time temperature is greater than or equal to the first temperature threshold, the movement of the first air guide structure of the air conditioner is controlled so that the angle between the first air guide structure and the side wall of the air conditioner is within the first angle range.

[0040] Furthermore, when the air conditioner is in cooling mode, the control method also includes:

[0041] When the first real-time temperature is greater than or equal to the second temperature threshold and less than the first temperature threshold, the movement of the first air guide structure of the air conditioner is controlled so that the angle between the first air guide structure and the side wall of the air conditioner is within the second angle range.

[0042] Furthermore, when the air conditioner is in cooling mode, the control method also includes:

[0043] When the first real-time temperature is less than the second temperature threshold, the movement of the first air guide structure of the air conditioner is controlled so that the angle between the first air guide structure and the side wall of the air conditioner is within the third angle range.

[0044] Furthermore, when the air conditioner is in heating mode, the control method also includes:

[0045] Obtain the second real-time indoor temperature;

[0046] When the second real-time temperature is less than or equal to the third temperature threshold, the movement of the second air guide structure of the air conditioner is controlled so that the angle between the second air guide structure and the bottom wall of the air conditioner is within the fourth angle range.

[0047] Furthermore, when the air conditioner is in heating mode, the control method also includes:

[0048] When the second real-time temperature is greater than the third temperature threshold and less than or equal to the fourth temperature threshold, the movement of the second air guide structure of the air conditioner is controlled so that the angle between the second air guide structure and the bottom wall of the air conditioner is within the fifth angle range.

[0049] Furthermore, when the air conditioner is in heating mode, the control method also includes:

[0050] When the second real-time temperature is greater than the fourth temperature threshold, the movement of the second air guide structure of the air conditioner is controlled so that the angle between the second air guide structure and the bottom wall of the air conditioner is within the sixth angle range.

[0051] When the air conditioner is in cooling mode, the controller drives the wind deflector to move to the first position. At this time, the wind deflector closes the upper air vent and opens the side air vent, so that the airflow is discharged only through the side air vent, thus preventing the cold air from blowing directly onto the ceiling.

[0052] When the air conditioner switches to heating mode, the controller drives the deflector structure to the second position. At this time, the deflector structure opens the upper air vent and the side air vent simultaneously, forming a composite airflow path of upper and side air intake to cooperate with the air outlet of the lower air vent or to achieve airflow circulation throughout the house, thereby automatically adjusting the opening and closing state of the air vents according to the cooling and heating conditions.

[0053] The variable opening and closing mechanism of this windbreak structure enables precise airflow control for different operating conditions, including cooling and heating:

[0054] In cooling mode, the top air vent is closed and only the side air vent is open, which effectively avoids condensation, dripping water and mold problems caused by cold air blowing directly on the ceiling. At the same time, it reduces the high resistance of the top air outlet and improves the cooling air volume and cooling speed.

[0055] In heating mode, opening both the top and side air vents simultaneously increases the air intake / exhaust area, which not only solves the problem of poor air intake when installed at a high position, but also optimizes the airflow distribution in the room through the synergistic effect of multiple air vents, improving heat exchange efficiency and heating comfort, while also helping to reduce the energy consumption of the air conditioner.

[0076] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0077] As a crucial household appliance for regulating indoor temperature and humidity, air conditioners directly impact indoor airflow distribution and user comfort through their air delivery method. Existing reversible air conditioners typically employ a cross-flow duct system, consisting of an upper and lower air outlet volute, each equipped with an independent movement mechanism to control the airflow path. Through coordinated movement, the air conditioner can switch the internal airflow direction, transitioning between "top intake, bottom exhaust" and "bottom intake, top exhaust" modes. This design is primarily based on fluid mechanics principles, aiming to align with the physical laws of cold air sinking and hot air rising: in cooling mode, bottom intake and top exhaust utilize the sinking characteristic of cold air; in heating mode, top intake and bottom exhaust utilize the rising characteristic of hot air, achieving faster temperature regulation efficiency.

[0078] However, in the existing technology, when using the top-discharge mode for cooling, the cold air from wall-mounted air conditioners, which are usually installed at a high position, can easily cause the ceiling surface temperature to drop too low, leading to condensation, dripping water, or even mold. At the same time, the cold air mixes with the surrounding air during its ascent, resulting in some energy loss. Secondly, in cooling mode, the evaporator is usually located upstream or in a specific position in the air duct. When using the top-discharge mode, the airflow path resistance is large, resulting in insufficient actual cooling air volume. Furthermore, since the air outlet is located at the top, the airflow cannot directly cover the area where people are active, resulting in slow cooling speed and poor user experience.

[0079] To address the aforementioned issues, this technical solution provides an air conditioner and control method to resolve the problems in the prior art where upward airflow during cooling can easily lead to ceiling condensation and mold growth, as well as insufficient airflow, and downward airflow during heating can result in poor air intake and unstable airflow.

[0080] Example 1

[0081] like Figures 1 to 10 As shown, this application embodiment provides an air conditioner, including:

[0082] The housing 100 has a top wall 101 and a bottom wall 102 disposed opposite to each other, and a side wall 103 disposed between the top wall 101 and the bottom wall 102;

[0083] The windward opening 200, the side opening 300, and the leeward opening 400 are interconnected. The windward opening 200 is located on the top wall 101, the side opening 300 is located on the side wall 103, and the leeward opening 400 is located on the bottom wall 102.

[0084] A windbreak structure 500 is movably disposed within a housing 100 to open or close at least one of an upper vent 200 and a side vent 300;

[0085] When the air conditioner is in cooling mode, the wind deflector 500 moves to the first position so that the side air vent 300 is open and the top air vent 200 is closed. When the air conditioner is in heating mode, the wind deflector 500 moves to the second position so that both the side air vent 300 and the top air vent 200 are open.

[0086] When the air conditioner starts the cooling mode, the controller drives the wind deflector 500 to move to the first position. At this time, the wind deflector 500 closes the upper air vent 200 located on the top wall 101 and opens the side air vent 300 located on the side wall 103, guiding the cold airflow mainly through the side air vent 300 to be sent to the front or bottom of the room.

[0087] When the air conditioner switches to heating mode, the controller drives the wind deflector 500 to move to the second position. At this time, the wind deflector 500 opens the upper air vent 200 and the side air vent 300 at the same time, forming a combined air intake or exhaust airflow channel at the top and side to cooperate with the airflow circulation of the lower air vent 400, thereby automatically adjusting the opening and closing state of the air vents according to the operating mode.

[0088] The variable opening and closing mechanism of this windbreak structure 500 enables airflow optimization for different operating conditions:

[0089] In cooling mode, the top air vent 200 is closed, leaving only the side air vent 300 open to air out. This effectively avoids condensation, dripping water, and mold problems caused by cold air blowing directly onto the ceiling. At the same time, it reduces the wind resistance of the air coming out from the top, improving cooling efficiency and cooling speed.

[0090] In heating mode, opening the top air vent 200 and the side air vent 300 simultaneously significantly increases the airflow interaction area, solves the problem of poor air intake caused by the high installation position, and promotes the uniform distribution of hot air in the room through the synergistic effect of multiple air vents, improving heating comfort and also helping to reduce the energy consumption of the air conditioner.

[0091] Furthermore, air conditioners also include:

[0092] A temperature sensing element is installed on the housing 100 to detect the real-time temperature inside the room;

[0093] The first air guide structure 600 is located at the side air outlet 300 and is electrically / communicationally connected to the temperature detection element;

[0094] The first air guide structure 600 is rotatably configured to adjust the first rotation angle of the first air guide structure 600 relative to the side wall 103 according to the real-time temperature, so as to adjust the flow direction of the airflow from the side air outlet 300.

[0095] During the operation of the air conditioner, the temperature detection device collects the indoor ambient temperature in real time and transmits the signal to the control unit. The control unit generates corresponding control commands based on the comparison between the current temperature and preset thresholds (such as rapid cooling / heating zone, comfort zone). This drives the first air guide structure 600 to rotate, thereby dynamically adjusting its first rotation angle relative to the side wall 103. This allows the airflow from the side air outlet 300 to be precisely directed to different areas of the room (such as blowing directly to the human activity area, blowing upwards to the ceiling to form a circulation, or blowing horizontally to the upper part of the room), thus achieving automatic adjustment of the airflow direction according to changes in indoor heat load.

[0096] Through the linkage control of the temperature detection element and the first air guide structure 600, intelligent and precise adjustment of airflow guidance is realized, avoiding the discomfort caused by cold or hot air blowing directly on the human body. At the same time, the airflow diffusion range is flexibly adjusted according to changes in room temperature (such as concentrated air supply when cooling rapidly, and dispersed air supply when the temperature is suitable to form whole-house circulation), which significantly improves the thermal comfort of users and improves the heat exchange efficiency of air conditioner in cooling or heating conditions and the uniformity of airflow organization in space.

[0097] Furthermore, air conditioners also include:

[0098] The second air guide structure 700 is located at the downwind outlet 400 and is electrically / communicationally connected to the temperature detection element;

[0099] The second air guide structure 700 is rotatably configured to adjust the second rotation angle of the second air guide structure 700 relative to the bottom wall 102 according to the real-time temperature, so as to adjust the flow direction of the airflow from the downwind outlet 400.

[0100] During air conditioner operation, temperature sensors continuously monitor the real-time indoor temperature and feed the data back to the control system.

[0101] Based on the comparison between the current room temperature and the preset temperature threshold (which will be explained in detail later), the control system outputs a control signal to drive the second air guide structure 700 to rotate around the axis, thereby dynamically adjusting its second rotation angle relative to the bottom wall 102, so that the airflow discharged from the downwind outlet 400 can be ejected along a specific trajectory (for example, blowing vertically downwards to quickly heat the ground when heating at low temperatures, or blowing horizontally to form a ground airflow circulation when the temperature is suitable), thus achieving adaptive adjustment of the airflow direction.

[0102] By adjusting the independent angle of the second air guide structure 700, the precise guidance of the downward airflow is achieved, effectively solving the problems of fixed airflow impact and limited coverage of traditional downward airflow air conditioners.

[0103] In heating mode, adjusting the angle ensures that the hot airflow effectively reaches the ground and diffuses evenly, preventing hot air from accumulating at the top, thereby improving heating efficiency and space temperature uniformity.

[0104] In cooling mode, a proper angle setting can prevent cold air from blowing directly onto the ground and causing localized overcooling. Combined with whole-house airflow circulation, it significantly improves user comfort and the overall energy efficiency of the air conditioning system.

[0105] Furthermore, such as Figure 11 As shown, the first air guiding structure 600 includes:

[0106] A first support member 601 is rotatably disposed at the side air vent 300. The first support member 601 is a support plate and is provided with a first communication hole for connecting the chamber of the housing 100 to the outside. Multiple first communication holes are provided to adjust the direction of the airflow exiting from the side air vent 300 by adjusting the position of the first support member 601. Specifically, for example... Figures 3 to 6 As shown;

[0107] A first filter component 602 is disposed on a first support component 601, and the first filter component 602 has a first filter hole that communicates with a first connecting hole.

[0108] The first filter component 602 includes a first filter bracket 6023 and a first filter screen 6024. The first filter bracket 6023 is disposed on the first support component 601 and is also provided with a plurality of filter communication holes. The first filter screen 6024 is disposed on the side of the first filter bracket 6023 away from the first support component 601. The first support component 601, the first filter bracket 6023 and the first filter screen 6024 can be integrally formed.

[0109] During the operation of the air conditioner, the first air guide structure 600 rotates synchronously with the first support component 601 to adjust the airflow direction. At this time, the first connecting hole on the first support component 601 is aligned and connected with the filter connecting hole and the first filter hole of the first filter component 602 (including the first filter bracket 6023 and the first filter screen 6024) located at the side air outlet 300, forming an airflow channel from the cavity of the housing 100 through the first filter screen 6024, through the first filter connecting hole and the first connecting hole, and finally out of the side air outlet 300.

[0110] When cleaning is required, since the first support component 601, the first filter bracket 6023 and the first filter screen 6024 can be integrally formed or tightly fitted, the user can easily remove or flip the integrated component from the side air vent 300 to clean or replace the dust attached to the surface of the first filter screen 6024.

[0111] By integrating the air guiding function and the filtration function into the first air guiding structure 600, an integrated design of air guiding and dust filtration is achieved. Not only does the rotation of the first support component 601 enable flexible adjustment of the airflow direction, but the first filter screen 6024 also effectively intercepts dust and impurities in the air, protecting the internal fan and evaporator from contamination and extending the service life of the equipment.

[0112] Meanwhile, the integrated or tightly fitted structure of the first support component 601, the first filter bracket 6023 and the first filter screen 6024 simplifies the number of parts, reduces assembly difficulty and cost, and the multi-hole array design (first connecting hole and first filter hole) ensures airflow passage while dispersing airflow resistance, avoiding noise problems caused by excessive local wind pressure, and improving user experience and product cleanliness.

[0113] Furthermore, the first air guiding structure 600 also includes:

[0114] The first driving element is disposed on the housing 100. The driving end of the first driving element is connected to the first support member 601 in a transmission manner so as to drive the first support member 601 to rotate. Specifically, the first driving element is a drive motor.

[0115] The controller is electrically / communically connected to both the temperature sensor and the first drive element to adjust the first rotation angle between the first support member 601 and the side wall 103 based on the detection result of the temperature sensor.

[0116] During the operation of the air conditioner, the temperature detection device collects indoor ambient temperature data in real time and transmits it to the controller. The controller calculates the required optimal airflow guidance angle based on the deviation between the current room temperature and the preset target temperature or comfort range, and then sends a control signal to the first drive element (drive motor).

[0117] After receiving the signal, the first driving element starts and drives the first support component 601 to rotate around the axis through its driving end, thereby precisely adjusting the first rotation angle of the first support component 601 relative to the side wall 103, thereby changing the spatial orientation of the first connecting hole and realizing the automatic and dynamic adjustment of the airflow direction discharged from the side air outlet 300.

[0118] By introducing closed-loop control of the first driving element and the controller, the airflow guidance is made intelligent and precise. The air supply angle can be automatically optimized according to the changes in indoor heat load without the need for manual intervention by the user. This avoids the discomfort caused by cold / hot air blowing directly on the human body, and can quickly establish an ideal airflow circulation according to the cooling or heating needs (such as dispersing the air upward to form a cold air cloud when cooling, and concentrating the air downward to quickly heat the ground when heating).

[0119] In addition, the motor-driven automatic adjustment has a fast response speed and accurate positioning, which improves the operating efficiency of the air conditioning system and the convenience of user operation, and significantly improves indoor thermal comfort.

[0120] Furthermore, the air conditioner also includes a third air guiding structure 800 disposed at the upwind vent 200, the third air guiding structure 800 comprising:

[0121] The second support component 801 is located at the upper air vent 200. Specifically, the second support component 801 is a support plate. The second support component 801 is provided with a second communication hole for connecting the cavity of the housing 100 with the outside. There are multiple third flow holes.

[0122] The second filter component 802 is disposed on the second support component 801. The second filter component 802 has a second filter hole that communicates with the second connecting hole. The second filter component 802 includes a second filter bracket 8021 and a second filter screen 8022 disposed on the second filter bracket 8021. The second support component 801, the second filter bracket 8021 and the second filter screen 8022 are integrally formed.

[0123] When the air conditioner is in cooling or heating mode and the upper air vent 200 is used as an air inlet or air outlet to participate in airflow circulation, the air flows through the upper air vent 200 and is first filtered through the flow holes on the second support component 801, the second filter bracket 8021 and the second filter screen 8022, and then enters or exits the internal cavity of the housing 100.

[0124] Since the second support component 801, the second filter bracket 8021, and the second filter screen 8022 adopt an integrated molding structure, when cleaning is required, the user can directly remove or flip the integrated component as a whole to clean or replace the dust attached to the surface of the second filter screen 8022. The operation is simple and the parts are not easy to lose.

[0125] This design highly integrates the air guiding / circulation function and air purification function at the 200-meter upper air outlet. The second filter 8022 can effectively intercept dust and particulate matter entering the air conditioner, keeping the evaporator and air duct clean, thereby maintaining the high efficiency of heat exchange and air quality during long-term operation of the air conditioner.

[0126] Meanwhile, the integrated structure of the second support component 801, the second filter bracket 8021, and the second filter screen 8022 not only simplifies the assembly process and reduces production assembly costs and the risk of missing parts, but also improves the structural strength and sealing of the components, avoids abnormal noises caused by loose parts, and enhances the durability of the product and the user experience.

[0127] Furthermore, such as Figure 1As shown, the air conditioner also includes a fan assembly 900 disposed within the housing 100 to introduce airflow into the air conditioner via the fan assembly 900;

[0128] The windbreak structure 500 includes a windbreak plate component 501 movably disposed on the housing 100. The windbreak plate component 501 is disposed around the fan assembly 900 so that at least one of the upper air vent 200 and the side air vent 300 can be opened or closed by adjusting the position of the windbreak plate component 501.

[0129] During the operation of the air conditioner, the fan assembly 900 starts to generate airflow power, and at the same time, the baffle plate component 501 in the baffle structure 500 is displaced or rotated under the action of the drive mechanism (such as a motor or connecting rod, which is implied but not described in detail).

[0130] When in heating mode, the wind deflector component 501 moves to the first position, blocking the upper air vent 200 and opening the side air vent 300, guiding the airflow mainly through the side air vent 300 to enter and exit.

[0131] When in cooling mode, the baffle plate component 501 moves to the second position, and at the same time opens the upper air vent 200 and the side air vent 300, so that the airflow drawn in or discharged by the fan assembly 900 can be exchanged with the outside through these two air vents at the same time, thereby realizing the switching of air path under different operating conditions.

[0132] By setting the baffle plate component 501 around the fan assembly 900 and directly participating in the air path switching, the air pressure difference generated by the fan is used to assist the sealing and opening of the baffle plate, simplifying the complex mechanical linkage structure of the external air duct.

[0133] This design not only enables flexible and independent control of the upper air vent 200 and the side air vent 300, ensuring the effective execution of the airflow strategy of avoiding ceiling obstruction during heating and expanding the air intake area during cooling, but also improves the response speed and sealing reliability of air duct switching, reduces the overall structural complexity and manufacturing cost, and enhances the overall energy efficiency ratio and operational stability of the air conditioning system.

[0134] Furthermore, the windbreak structure 500 also includes:

[0135] A rotating component is disposed within the housing 100 and extends along a first direction. A wind deflector component 501 is disposed on the rotating component. Specifically, the rotating component is a rotating bearing.

[0136] A drive assembly is disposed within the housing 100. The drive end of the drive assembly is connected to the rotating component to drive the rotating component to rotate around a first direction, thereby causing the wind deflector component 501 to rotate between the upper air vent 200 and the side air vent 300, so as to open or close at least one of the upper air vent 200 and the side air vent 300.

[0137] When the air conditioner is running, the drive assembly receives a control signal and starts, and its drive end drives the rotating parts (such as rotating bearings) to rotate around the first direction;

[0138] Since the wind deflector component 501 is fixedly mounted on the rotating component, as the rotating component rotates, the wind deflector component 501 moves inside the housing 100, thereby changing its coverage state relative to the upper air vent 200 and the side air vent 300.

[0139] In cooling mode, the wind deflector component 501 rotates to the first position to close the upper air vent 200 and expose the side air vent 300.

[0140] In heating mode, the baffle plate component 501 rotates to the second position to simultaneously expose the upper air vent 200 and the side air vent 300, thereby cooperating with the fan assembly 900 to achieve air path switching under different operating conditions.

[0141] By using a rotating component (bearing) extending along the first direction as a transmission medium, the linear or rotational motion of the drive component is converted into the smooth rotation of the baffle component 501, thereby achieving the compactness and standardization of the air path switching structure and reducing the assembly difficulty.

[0142] This rotary drive method makes the movement of the baffle component 501 smoother and more precise, effectively reducing mechanical wear and noise, ensuring the reliability and sealing of the switching between the upper air vent 200 and the side air vent 300, thereby ensuring the airflow requirements of large air intake during cooling and stable air intake during heating, and improving the overall quiet operation and service life of the unit.

[0143] Furthermore, the driving components include:

[0144] The second driving element is disposed inside the housing 100. The driving end of the second driving element is provided with a first meshing member, and the rotating component is provided with a second meshing member. Specifically, the second driving element is a drive motor, the first meshing member is a first gear disposed on the driving end of the second driving element, and the second meshing member is a second gear disposed on the rotating component.

[0145] The transmission component is respectively disposed on the first meshing member and the second meshing member, and meshes with the first meshing member and the second meshing member respectively, so that when the second driving element drives the first meshing member to rotate, the power is transmitted to the second meshing member through the transmission component, so that the rotating component is driven to rotate through the second meshing member. Specifically, the transmission component is a rack and pinion.

[0146] After the air conditioner is turned on, the controller sends a command to the second drive element (drive motor), which starts and drives the first meshing part (first gear) on its output shaft to rotate.

[0147] The first gear meshes with the transmission component (rack) to convert rotational motion into linear motion, driving the rack to move in a straight line.

[0148] The rack meshes with the second meshing element (second gear) on the rotating component (bearing), thereby converting the linear motion of the rack into the rotational motion of the second gear and the rotating component;

[0149] The rotation of the rotating component drives the wind deflector component 501 fixed thereon to rotate, thereby realizing the opening and closing switching of the wind deflector component 501 between the upper air vent 200 and the side air vent 300.

[0150] The drive assembly adopts a gear-rack-gear transmission method, which converts the rotational motion of the motor into the rotational motion of the baffle. Compared with direct drive, this structure has the advantages of smooth transmission, low noise, and uniform force distribution, effectively avoiding the jamming or abnormal noise that may be caused by direct drive.

[0151] Meanwhile, the gear transmission has a large reduction ratio, which can provide sufficient driving torque to overcome wind pressure resistance while ensuring that the wind deflector component 501 rotates at an appropriate speed. This ensures that the wind deflector can accurately and reliably stay in the designated position under high-pressure airflow conditions, thus achieving high-precision control and high-reliability operation of the wind path switching.

[0152] Example 2

[0153] This application embodiment also provides a control method applied to the above-mentioned air conditioner, the control method comprising:

[0154] When the air conditioner is in cooling mode, control the movement of the air deflector 500 of the air conditioner so that the side air vent 300 of the air conditioner is in the open state and the top air vent 200 of the air conditioner is in the closed state.

[0155] When the air conditioner is in heating mode, control the movement of the wind deflector 500 so that both the side air vent 300 and the top air vent 200 are in the open state.

[0156] During the operation of the air conditioner, the controller first identifies the current operating mode;

[0157] When the controller detects that the user has set the cooling mode, it sends a control signal to the drive component to drive the wind deflector structure 500 to the first position. At this time, the wind deflector component 501 blocks the upper air outlet 200, leaving only the side air outlet 300 as the air inlet / outlet channel. Together with the first air guide structure 600 (lower / front air outlet) and the second air guide structure 700 (lower air outlet) mentioned above, a specific airflow path is achieved during cooling.

[0158] When the controller detects that the user has set the mode to heating, it sends another control signal to the drive component, which drives the wind deflector structure 500 to move to the second position. At this time, the wind deflector component 501 opens the upper air vent 200, so that the side air vent 300 and the upper air vent 200 open at the same time, forming a double-sided air intake / exhaust pattern. This, together with the fan component 900, generates a larger air volume or a different airflow organization mode to meet the heating demand.

[0159] This control method directly controls the opening and closing state of the windbreak structure through simple pattern recognition, thereby optimizing the airflow path for different operating conditions.

[0160] In cooling mode, closing the top air vent 200 can avoid the risk of condensation caused by cold air blowing directly onto the ceiling, and the side air vent 300, in conjunction with the air guiding structure, can effectively diffuse the cold air and quickly cool it down.

[0161] In heating mode, opening both the top air vent 200 and the side air vent 300 simultaneously can significantly increase the air intake area, reduce air intake resistance, and improve fan efficiency, thereby ensuring the large air volume required for heating. At the same time, combined with the physical property of hot air rising, it helps to distribute heat evenly in the room, improving heating efficiency and user experience.

[0162] Furthermore, when the air conditioner is in cooling mode, the control method also includes:

[0163] Obtain the first real-time indoor temperature;

[0164] When the first real-time temperature is greater than or equal to the first temperature threshold, the first air guide structure 600 of the air conditioner is controlled to move so that the angle between the first air guide structure 600 and the side wall 103 of the air conditioner is within the first angle range. Specifically, the first temperature threshold is 30° in this embodiment, and the first angle range is 30°~60° in this embodiment. In this embodiment, the angle between the first air guide structure 600 and the side wall 103 of the air conditioner can be any one of 31°, 32°, and 60°.

[0165] When the air conditioner is in cooling mode and the deflector structure 500 has controlled the side air vent 300 to open and the top air vent 200 to close, the controller obtains the first real-time indoor temperature through the temperature detection device.

[0166] When the first real-time temperature is determined to be greater than or equal to the first temperature threshold (e.g., 30°C), it indicates that the indoor temperature is high and the user has a strong need for cooling.

[0167] At this time, the controller sends a signal to the first driving element to drive the first air guide structure 600 to rotate, so that the angle between it and the side wall 103 of the air conditioner is adjusted to the first angle range (for example, between 30° and 60°, specifically 31°, 32° or 60°, etc.), thereby guiding the cold air flowing out from the side air outlet 300 to blow directly to the lower part of the room or the area where people are active at a larger downward tilt angle, so as to achieve rapid cooling.

[0168] This control strategy achieves fine-tuning of airflow angle through temperature feedback. When the room temperature is high and cooling is urgently needed, by adjusting the first air guide structure to a larger downward blowing angle (30°~60°), the natural upward characteristic of cold air can be overcome, allowing the cold air to reach the human activity area or the bottom of the room more effectively, significantly shortening the cooling response time and improving the rapid cooling effect.

[0169] At the same time, this angle range can ensure the coverage of airflow while avoiding localized overcooling or discomfort caused by excessively vertical airflow, thus achieving a balance between cooling efficiency and comfort.

[0170] Furthermore, when the air conditioner is in cooling mode, the control method also includes:

[0171] When the first real-time temperature is greater than or equal to the second temperature threshold and less than the first temperature threshold, the first air guide structure 600 of the air conditioner is controlled to move so that the angle between the first air guide structure 600 and the side wall 103 of the air conditioner is within the second angle range. Specifically, the second temperature threshold is 26°C in this embodiment, and the second angle range is 15°~30° in this embodiment, wherein the second angle range does not include 15° in this embodiment.

[0172] When the air conditioner is running continuously in cooling mode, the controller monitors the first real-time indoor temperature in real time through temperature detection devices. When the system determines that the first real-time temperature is between the second temperature threshold (26℃) and the first temperature threshold (30℃) (i.e., 26℃ ≤ T < 30℃), it indicates that the indoor temperature has decreased but is still slightly higher than the comfort zone or the user-set reference temperature.

[0173] At this time, the controller controls the first driving element to rotate, thereby adjusting the angle between the first air guide structure 600 and the side wall 103 of the air conditioner to the second angle range (e.g., between 15° and 30°, specifically 16°, 20°, 25°, etc., but excluding 15°).

[0174] At this angle, the cool air discharged from the side vent 300 blows downward or forward at a smaller angle, forming a gentle airflow that avoids blowing directly on the human body.

[0175] This control strategy enables staged comfortable airflow during the cooling process:

[0176] When the room temperature is slightly high (26℃~30℃), a smaller air outlet angle (15°~30°, excluding 15°) is used. This ensures a certain cooling effect to maintain a stable room temperature, while significantly reducing wind speed and impact, preventing discomfort caused by direct cold air blowing, and improving the user's physical experience in a semi-comfortable state.

[0177] Furthermore, when the air conditioner is in cooling mode, the control method also includes:

[0178] When the first real-time temperature is less than the second temperature threshold, the first air guide structure 600 of the air conditioner is controlled to move so that the angle between the first air guide structure 600 and the side wall 103 of the air conditioner is within the third angle range. Specifically, the third angle range is 0° to 15° in this embodiment, wherein the third angle range does not include 0° in this embodiment.

[0179] The air conditioner runs continuously in cooling mode, and the controller monitors the first real-time indoor temperature through temperature detection devices.

[0180] When the system determines that the first real-time temperature is less than the second temperature threshold (26℃), it indicates that the indoor temperature has reached or fallen below the user's set comfort target, and there is no need for strong cooling or direct airflow.

[0181] The controller controls the first driving element to rotate the first air guide structure 600 and adjust the angle between the first air guide structure 600 and the side wall 103 of the air conditioner to a third angle range (e.g., between 0° and 15°, specifically 1°, 5°, 10°, etc., but excluding 0°).

[0182] At this angle, the airflow is almost parallel to the side wall or only slightly downward, forming a horizontal or slightly downward diffused airflow, thus preventing the cold air from directly affecting the human body.

[0183] This control strategy achieves seamless and comfortable airflow at the end of the cooling process:

[0184] When the room temperature is suitable (T < 26℃), a very small air outlet angle (0°~15°, excluding 0°) is used to make the airflow flow horizontally along the ceiling or the upper space of the room. The principle of natural sinking of cold air is used to circulate the whole room, which not only avoids the risk of joint discomfort or cold caused by direct wind blowing on the human body, but also promotes the uniform mixing of the air in the room and maintains the stability of temperature.

[0185] Furthermore, when the air conditioner is in heating mode, the control method also includes:

[0186] Obtain the second real-time indoor temperature;

[0187] When the second real-time temperature is less than or equal to the third temperature threshold, the second air guide structure 700 of the air conditioner is controlled to move so that the angle between the second air guide structure 700 and the bottom wall 102 of the air conditioner is within the fourth angle range. Specifically, the third temperature threshold is 20°C in this embodiment, and the fourth angle range is 30°~45° in this embodiment. In this embodiment, the fourth angle range does not include 30°.

[0188] When the air conditioner is in heating mode and the air deflector 500 has controlled the upper air vent 200 and the side air vent 300 to be in the open state, the controller obtains the second real-time indoor temperature through the temperature detection device.

[0189] When the second real-time temperature is determined to be less than or equal to the third temperature threshold (e.g., 20°C), it indicates that the indoor temperature is low and the user has a strong need to raise the temperature.

[0190] At this time, the controller sends a signal to the second drive element (drive motor) to drive the air guide plate (such as air guide plate 3 or air guide plate 4) in the second air guide structure 700 to rotate, so that the angle between it and the bottom wall 102 of the air conditioner is adjusted to the fourth angle range (for example, between 30° and 45°, specifically 31°, 35°, 40°, etc., but not including 30°).

[0191] At this angle, the hot air discharged from the downwind vent blows directly onto the floor or the area where people are active at a large downward angle, taking advantage of the sinking property of hot air to quickly heat the floor and the space around people.

[0192] This control strategy enables rapid heating in heating mode:

[0193] When the room temperature is low and heating is urgently needed, by adjusting the second air guide structure 700 to a larger downward blowing angle (30°~45°, excluding 30°), the natural upward floating characteristic of hot air can be overcome, allowing the hot airflow to reach the bottom of the room and the feet of the human body more effectively, significantly shortening the heating response time and improving the rapid heating effect.

[0194] At the same time, this angle range can ensure the coverage of the hot airflow while avoiding local overheating or discomfort caused by excessively vertical airflow, thus achieving a balance between heating efficiency and comfort.

[0195] Furthermore, when the air conditioner is in heating mode, the control method also includes:

[0196] When the second real-time temperature is greater than the third temperature threshold and less than or equal to the fourth temperature threshold, the second air guide structure 700 of the air conditioner is controlled to move so that the angle between the second air guide structure 700 and the bottom wall 102 of the air conditioner is within the fifth angle range. Specifically, the fourth temperature threshold is 24°C in this embodiment, and the fourth angle range is 45°~75° in this embodiment. In this embodiment, the fifth angle range does not include 45°.

[0197] When the air conditioner is in heating mode and the air deflector 500 has controlled the upper air vent 200 and the side air vent 300 to be in the open state, the controller monitors the second real-time temperature in the room in real time through the temperature detection device.

[0198] When the system determines that the second real-time temperature is between the third temperature threshold (20℃) and the fourth temperature threshold (24℃) (i.e., 20℃ < T ≤ 24℃), it indicates that the indoor temperature is slightly low, and the user feels slightly cold but there is no need to heat up the room rapidly.

[0199] At this time, the controller controls the second drive element to rotate, thereby adjusting the angle between the second air guide structure 700 and the bottom wall 102 of the air conditioner to the range of the fifth angle (e.g., between 45° and 75°, specifically 50°, 60°, 70°, etc., but excluding 45°).

[0200] At this angle, the hot air expelled from the downwind vent blows forward or downward at a greater angle, forming a gentle airflow that covers the lower and middle parts of the body's activity area, preventing hot air from blowing directly on the head.

[0201] This control strategy achieves progressive and comfortable airflow during the heating process:

[0202] When the room temperature is slightly low (20℃~24℃), a larger air outlet angle (45°~75°, excluding 45°) is adopted. This ensures that the hot air can effectively sink to the human activity area and provide obvious warmth. At the same time, the larger angle avoids the hot air blowing directly on the upper part of the human body and face, preventing discomfort such as dryness and dizziness caused by direct hot air blowing.

[0203] Furthermore, when the air conditioner is in heating mode, the control method also includes:

[0204] When the second real-time temperature is greater than the fourth temperature threshold, the second air guide structure 700 of the air conditioner is controlled to move so that the angle between the second air guide structure 700 and the bottom wall 102 of the air conditioner is within the sixth angle range. In this embodiment, the sixth angle range is 75°~90°, but in this embodiment, the sixth angle range does not include 75°.

[0205] When the air conditioner is in heating mode and the air deflector 500 has controlled the upper air vent 200 and the side air vent 300 to be in the open state, the controller monitors the second real-time temperature in the room in real time through the temperature detection device.

[0206] When the system determines that the second real-time temperature is greater than the fourth temperature threshold (24℃), it indicates that the indoor temperature has reached or exceeded the user's set comfort target. At this time, there is no need for strong heating or direct airflow.

[0207] The controller controls the second drive element to rotate the second air guide structure 700 and adjusts the angle between the second air guide structure 700 and the bottom wall 102 of the air conditioner to the sixth angle range (e.g., between 75° and 90°, specifically 80°, 85°, etc., but excluding 75°).

[0208] At this angle, the airflow is almost parallel to the floor or discharged with a very small forward tilt angle, forming a horizontal airflow or a slightly forward diffused airflow, avoiding the hot air from directly acting on the feet of the human body or causing local overheating.

[0209] This control strategy achieves seamless and comfortable airflow at the end of the heating period:

[0210] When the room temperature is suitable (T > 24℃), use a very large air outlet angle (75°~90°, excluding 75°) to make the airflow flow horizontally along the lower part of the room. Combined with the natural rising characteristic of hot air, this promotes the uniform mixing of heat in the room and avoids discomfort caused by excessively high temperatures near the ground.

[0211] This air supply method avoids the dryness or heat caused by direct airflow onto the human body, while maintaining the stability of the overall room temperature and improving the user's comfort in a warm environment. Excluding the 75° boundary value may be to ensure that the airflow has sufficient horizontal diffusion capacity, preventing the airflow from being too vertically upward and causing heat to accumulate rapidly in the ceiling area, thereby achieving efficient whole-house airflow circulation.
