[0002] Currently, in the field of indoor floor-standing air conditioners, the installation method of existing floor-standing air conditioners determines their fixed position indoors. Once installed, subsequent movement or self-adjustment is often inconvenient. Although existing floor-standing air conditioners can adjust the airflow direction to a certain extent through the swing design of the air guide plate, the limited angle makes it difficult to completely avoid cold air blowing directly on people, especially in summer cooling mode. Direct cold air may cause discomfort to users, leading to colds or other health problems. Existing methods to prevent direct blowing in floor-standing air conditioners usually involve closing the air outlet facing the user or dividing the air conditioner into upper and lower airflow zones, using only the upper airflow zone when cooling. However, these methods may result in some areas of the room not receiving effective cooling due to reduced airflow, thus sacrificing some cooling function and room comfort. In addition, the fixed position of floor-standing air conditioners also makes daily cleaning and maintenance of the corner where the air conditioner is located difficult for households, making cleaning work often tedious and time-consuming.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, an embodiment of the present invention provides a vertical air conditioner chassis assembly, including: a support base 10, multiple rotating wheel structures 20, and multiple lifting structures 30; the upper part of the support base 10 is used to support a vertical air conditioner indoor unit 40; the multiple rotating wheel structures 20 are spaced apart at the lower part of the support base 10, and the multiple rotating wheel structures 20 together drive the support base 10 to move and rotate, so as to adjust the air outlet orientation of the vertical air conditioner indoor unit 40; the multiple lifting structures 30 are spaced apart at the lower part of the support base 10, and the multiple lifting structures 30 together drive the support base 10 to move up and down; wherein, when it is necessary to clean the area below the support base 10, the multiple lifting structures 30 drive the support base 10 to rise, so as to increase the gap between the support base 10 and the ground.

[0029] This invention, through the coordinated operation of a support base 10, multiple rotating wheel structures 20, and multiple lifting structures 30, achieves the support, movement, rotation, and lifting adjustment of a vertical air conditioner indoor unit 40 using a simple structure. This allows the air outlet of the vertical air conditioner indoor unit 40 to have freedom of movement, rotation, and lifting, freeing the air outlet angle from the limitations of the original air guiding structure. Structurally, it avoids direct airflow onto the human body, especially preventing cold air from blowing directly on people in cooling mode, thus improving user comfort. The lifting structures 30 increase the space between the support base 10 and the ground, facilitating subsequent adjustments to the support base. Cleaning under the base 10: By setting a rotating wheel structure 20, the support base 10 can be driven away from the long-term stationary position, which also facilitates thorough cleaning of the ground by the user; The vertical air conditioner chassis component proposed in this invention can work efficiently with the vertical air conditioner indoor unit 40, so that the vertical air conditioner indoor unit 40 does not need to sacrifice part of the air conditioner's cooling function and room comfort to avoid direct cold air blowing on the user. The present invention has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of existing vertical air conditioners that cannot be moved or rotated, resulting in direct cold air blowing on the user and difficulty in cleaning the location of the vertical air conditioner. It is suitable for large-scale promotion and use.

[0030] like Figure 1 and Figure 2 As shown, the rotating wheel structure 20 includes a drive motor 21, a transmission part 22, and a universal wheel 23. The drive motor 21 is fixedly installed at the lower part of the support base 10. The transmission part 22 is driven and connected to the drive motor 21 and the universal wheel 23 respectively. The drive motor 21 drives the transmission part 22 to rotate. The transmission part 22 is used to reduce speed and increase torque to drive the universal wheel 23 to rotate.

[0031] By employing a combination of drive motor 21 and transmission unit 22, sufficient torque can be provided to ensure smooth rotation of the universal wheel 23 in any direction. Through the rotation of drive motor 21, and after deceleration and torque amplification by transmission unit 22, the universal wheel 23 can achieve 360° free rotation, thereby driving the support base 10 and the vertical air conditioner indoor unit 40 to move flexibly within the room. This technology enables the vertical air conditioner indoor unit 40 to quickly respond to the user's movement needs, avoids direct cold air blowing on the human body, and improves the ease of cleaning the air conditioner.

[0032] In other embodiments of the present invention, the response speed and steering accuracy of the rotating wheel structure 20 can be further improved by employing a more efficient drive motor 21 and a more precise transmission part 22, thereby solving the technical problem of rapid and precise movement in narrow spaces.

[0033] like Figure 1 and Figure 2As shown, the rotating wheel structure 20 also includes a motor waterproof sleeve, which is fitted on the outer periphery of the drive motor 21 to seal the drive motor 21; the drive motor 21 is a stepper motor; and / or, the rotating wheel structure 20 also includes a steering part 24, which is disposed on the support base 10 and is drivenly connected to the universal wheel 23; the steering part 24 is used to control the movement direction of the universal wheel 23.

[0034] The waterproof sleeve for the motor, based on the encapsulation of waterproof material, ensures that the drive motor 21 can still operate normally in humid environments. The stepper motor was chosen because it can provide precise step control, enabling accurate steering of the universal wheel 23. The addition of the steering unit 24 makes the steering of the universal wheel 23 more flexible, enabling more complex path planning. The waterproof sleeve, stepper motor, and steering unit 24 work together to ensure the reliability and flexibility of the rotating wheel structure 20 in various environments. The above design improves the freedom of movement of the vertical air conditioner indoor unit 40, avoids cold air blowing directly on people, and enhances the durability and safety of the system.

[0035] In other embodiments of the present invention, the waterproof performance and steering accuracy of the rotating wheel structure 20 can be further improved by adopting existing more advanced waterproof technology and higher precision steering control technology, thereby solving the problem of movement and steering in extreme environments.

[0036] like Figure 3 As shown, the lifting structure 30 includes a hydraulic drive unit and a lifting rod. The hydraulic drive unit is mounted on the support base 10 and is driven to connect with the lifting rod. The hydraulic drive unit is used to drive the lifting rod to rise and fall. The end of the lifting rod away from the hydraulic drive unit is used to abut against the ground to support the support base 10 to rise and fall.

[0037] The hydraulic drive unit employs a hydraulic system, controlling the pressure and flow of hydraulic oil to achieve smooth raising and lowering of the lifting rod. The cooperation between the hydraulic drive unit and the lifting rod allows the support base 10 to be adjusted in distance from the ground as needed, facilitating cleaning and maintenance. These technologies enable the vertical air conditioner indoor unit 40 to achieve height adjustment, preventing cold air from blowing directly on people and improving the ease of cleaning the space under the support base 10.

[0038] In other embodiments of the present invention, the lifting problem in a non-hydraulic environment can also be solved by using an electric lifting mechanism or other mechanical lifting mechanism, while maintaining or improving the stability and safety of the lifting.

[0039] Specifically, the vertical air conditioner chassis assembly also includes at least one anti-collision sensor for detecting external objects to prevent the support base 10 and the vertical air conditioner indoor unit 40 from colliding with external objects in at least one of the states of movement, lifting, and rotation.

[0040] The anti-collision sensor proposed in this invention can employ sensing technologies such as infrared, ultrasonic, or laser to monitor the surrounding environment in real time, ensuring the safety of the support base 10 during movement and lifting. The anti-collision sensor is connected to a central controller; when a potential collision risk is detected, the central controller automatically adjusts the movement path of the support base 10 or stops its movement to avoid a collision. This configuration significantly improves the safety of the vertical air conditioner indoor unit 40 during movement, preventing collisions with external objects and protecting the air conditioner and the surrounding environment. In other embodiments of this invention, the obstacle avoidance capability and safety of the system can be further enhanced by adding more anti-collision sensors or employing more advanced radar scanning anti-collision technology, solving obstacle avoidance problems in complex environments.

[0041] Optionally, the vertical air conditioner chassis assembly also includes a limiting structure, which is disposed on the ground to limit the range of motion of the support base 10.

[0042] The limiting structure proposed in this invention can be a physical barrier or electronic fence installed on the ground to ensure that the supporting base 10 does not exceed the preset range of movement. The limiting structure is combined with the movement control system of the supporting base 10. When the supporting base 10 approaches the limiting structure, the movement control system automatically adjusts the movement direction or stops moving to prevent exceeding the range. This technology makes the movement of the vertical air conditioner indoor unit 40 more controllable, avoids movement beyond the preset range, and improves safety.

[0043] In other embodiments of the present invention, more flexible activity range control can be achieved by employing existing wireless signal-based electronic fences, thus solving the problem of activity range limitation in dynamic environments.

[0044] The present invention also provides a vertical air conditioner, which includes the aforementioned vertical air conditioner chassis assembly, a vertical air conditioner indoor unit 40, an infrared sensor, and a central controller; the vertical air conditioner indoor unit 40 is mounted on a support base 10; the central controller is electrically connected to the vertical air conditioner indoor unit 40, the infrared sensor, the rotating wheel structure 20, and the lifting structure 30 respectively, to control the vertical air conditioner indoor unit 40, the infrared sensor, the rotating wheel structure 20, and the lifting structure 30 to work together; the infrared sensor is used to detect human bodies; wherein, the infrared sensor obtains human body position data through infrared sensing detection, and the central controller controls the rotating wheel structure 20 and the lifting structure 30 to work according to the human body position data, so that the air outlet of the vertical air conditioner indoor unit 40 avoids human bodies.

[0045] Infrared sensors can accurately detect the position of a person, while the central controller processes the data through algorithms to adjust the airflow direction of the indoor unit in real time. The combination of the infrared sensors and the central controller enables the vertical indoor unit 40 to intelligently avoid blowing cold air directly onto people, improving user comfort. These technologies significantly enhance the intelligence level of the vertical indoor unit 40, preventing cold air from blowing directly onto people and improving the convenience of cleaning the space under the support base 10.

[0046] In other embodiments of the present invention, more comprehensive environmental monitoring and more intelligent air conditioning control can be achieved by adding more types of sensors, such as temperature sensors and humidity sensors, thereby solving the problems of comfort and energy saving in complex environments.

[0047] Specifically, the vertical air conditioner indoor unit 40 is detachably connected to the support base 10; the vertical air conditioner also includes a display screen, which is electrically connected to the central controller; the display screen shows virtual control buttons, which are used to control at least one of the vertical air conditioner indoor unit 40, the rotating wheel structure 20, and the lifting structure 30; and / or, the vertical air conditioner also includes physical buttons, which are electrically connected to the central controller; the physical buttons are used to control at least one of the vertical air conditioner indoor unit 40, the rotating wheel structure 20, and the lifting structure 30.

[0048] The detachable design allows the vertical air conditioner indoor unit 40 to be maintained and cleaned independently of the support base 10. The display screen and physical buttons provide a user interface for intuitive control of the air conditioner's functions. In principle, the display screen and physical buttons, through a central controller, enable direct user control of the indoor unit, the rotating wheel structure 20, and the lifting structure 30. This design significantly improves the user-friendliness of the vertical air conditioner indoor unit 40, allowing users to easily adjust the air conditioner's position and airflow direction, preventing cold air from blowing directly on people, and also improving the convenience of cleaning the space under the support base 10.

[0049] In other embodiments of the present invention, existing interactive technologies such as touch screens or voice control can be used to achieve a more convenient user control experience and solve the interaction problem under different user needs.

[0050] The present invention also provides a method for preventing direct airflow, which includes the above-mentioned vertical air conditioner. The method includes the following steps: detecting the distribution location information of indoor occupants; generating a real-time occupant distribution map based on the distribution location information of indoor occupants; and controlling the vertical air conditioner chassis assembly based on the occupant distribution map so that the air outlet of the vertical air conditioner indoor unit 40 avoids occupants.

[0051] The anti-direct-blow control method, based on infrared sensor human body detection technology and intelligent algorithms of the central controller, can adjust the air outlet direction of the indoor unit in real time to prevent cold air from blowing directly on people. By detecting the distribution location information of people indoors, a personnel distribution map is generated. The central controller adjusts the movement and lifting of the support base 10 and the air outlet direction of the indoor unit according to the personnel distribution map to achieve the anti-direct-blow effect. The above design significantly improves the user comfort and safety of the vertical air conditioner indoor unit 40, avoids cold air blowing directly on people, and also improves the convenience of cleaning the space under the support base 10.

[0052] In other embodiments of the present invention, more accurate human body detection and more intelligent anti-direct-blow control can be achieved by using technologies such as depth cameras, thereby solving the problem of anti-direct-blow in complex environments.

[0053] Specifically, the anti-direct-blow control method also includes: taking the space formed by the air outlet range of the vertical air conditioner indoor unit 40 as the direct-blow space, and taking other spaces outside the direct-blow space as the avoidance space; in cooling mode, adjusting the direct-blow space to avoid the human body, detecting the temperature in the avoidance space as T1, and the temperature in the direct-blow space as T2, when T1-T2≥1℃, increasing the air volume of the vertical air conditioner indoor unit 40 to reduce the temperature in the avoidance space; in heating mode, adjusting the air outlet of the vertical air conditioner indoor unit 40 to avoid or face the human body, detecting the temperature in the avoidance space as T1, and the temperature in the direct-blow space as T2, when T2-T1≥1℃, increasing the air volume of the vertical air conditioner indoor unit 40 to increase the temperature in the avoidance space.

[0054] The anti-direct-blow control method, through the intelligent algorithm of the central controller, can automatically adjust the air volume and direction of the air conditioner based on the indoor temperature distribution and the position of people. By detecting the temperature difference between the space directly exposed and the space to be avoided, it automatically adjusts the air volume when the temperature difference reaches a preset value to ensure a balanced indoor temperature. This design significantly improves the temperature control accuracy of the indoor unit 40 of the vertical air conditioner, avoids excessive cooling or heating in localized areas, and enhances user comfort.

[0055] In other embodiments of the present invention, more precise temperature regulation can be achieved by employing intelligent temperature control algorithms, including but not limited to temperature prediction and control based on machine learning, thereby solving the temperature control problem in complex environments.

[0056] It is worth noting that, in one embodiment of the present invention, during use, the vertical air conditioner chassis assembly achieves omnidirectional movement and height adjustment of the indoor unit through the rotating wheel structure 20 and the lifting structure 30. First, the user can control the movement and lifting of the support base 10 via physical buttons or virtual control buttons on the display screen. During movement, anti-collision sensors monitor the surrounding environment in real time to ensure that the support base 10 does not collide with external objects. Simultaneously, the limiting structure restricts the range of motion of the support base 10, preventing movement beyond the preset range. In cooling or heating mode, infrared sensors detect the distribution of people indoors, and the central controller adjusts the movement and lifting of the support base 10, as well as the airflow direction of the indoor unit, based on the personnel distribution map to achieve an anti-direct-blow effect. When the temperature difference between the directly blown space and the avoidance space reaches a preset value, the central controller automatically adjusts the airflow of the vertical air conditioner indoor unit 40 to ensure a balanced indoor temperature. The entire working process demonstrates the technological advancement, intelligent principle, and comfortable and safe operation of the technical solution of this application, providing users with a more flexible, intelligent, and comfortable air conditioning experience.

[0057] The specific working process and principle of one embodiment of the present invention will now be described in detail as follows:

[0058] This invention provides a movable and liftable support base 10 and a control method for preventing direct cold air blowing. The support base 10 includes four rotating wheel structures 20 that can rotate and move 360° respectively. Each universal wheel 23 is equipped with a single-phase power supply motor (i.e., drive motor 21) that is driven by its own motor. The motor wires of the drive motor 21 are connected to the main board of the indoor unit of the vertical air conditioner. The vertical air conditioner has physical buttons, which allow users to freely operate the movement and lifting of the support base 10 by pressing the buttons. When the lifting structure 30 drives the universal wheel 23 to leave the ground, the universal wheel 23 can be retracted for subsequent cleaning of the support base 10. When the air outlet is below the 0, it avoids collisions; the support base 10 and the vertical air conditioner indoor unit 40 can be separate or integrated; the motor waterproof sleeve is made of plastic to prevent water dripping from the evaporator of the vertical air conditioner indoor unit 40 from causing short circuits or other malfunctions in the drive motor 21; the support base 10 has a built-in hydraulic rod (i.e., hydraulic drive unit), which can be remotely controlled to drive the lifting rod to freely adjust its height; the infrared sensor detects the human body in real time and monitors the user's position and activity status; the support base 10 automatically adjusts the air outlet angle or the position of the vertical air conditioner indoor unit 40 according to the detection results to ensure that the air outlet avoids the human body.

[0059] like Figure 4As shown, when the user places the vertical air conditioner indoor unit 40 in a corner of the room, the maximum rotation range of the vertical air conditioner indoor unit 40, driven by the vertical air conditioner chassis assembly, is determined according to the wall position. When the vertical air conditioner indoor unit 40 has two cross-flow air outlets, after the vertical air conditioner indoor unit 40 has been started and stabilized (approximately 10 minutes), within a 90° range where the vertical air conditioner indoor unit 40 is placed, the infrared sensor performs an infrared scan of the indoor space to generate specific personnel distribution information. For example, the maximum radius of the infrared scan is set to within 6 meters, and the specific location of each person is set as a point. The position detection error must be within 1°. After confirming the position, connect it to the nearest air outlet to form a line. Repeat this process for both cross-flow air outlets to create a direct-blowing space. Other indoor spaces should form a buffer zone. Set a minimum distance (0.5-1.5 meters) as the radius centered on the human body to create a user comfort zone. To ensure user comfort, ensure the direct-blowing space does not overlap with any user comfort zone. After the user comfort zone is basically fixed, adjust the sweeping structure on the vertical air conditioner indoor unit 40 to make the airflow more even and prevent direct airflow to the user. Figure 4 As shown, angles A and B are the maximum adjustment angles of the sweeping blades of the sweeping structure at the two air outlets. By controlling the universal swivel wheel 23 to adjust the position of the vertical air conditioner indoor unit 40, the direct blowing space is avoided from people, and the sweeping blades are swept at the maximum adjustment angle. This improves the temperature uniformity of the direct blowing space while avoiding direct blowing. When the infrared sensor detects a multi-person scene, the angle that avoids direct blowing for the most people is selected to divide the direct blowing space according to the principle of minimum interference.

[0060] In cooling mode, every 10 minutes, the indoor unit 40 of the vertical air conditioner detects the temperature in the sheltered space (T1) and the temperature in the directly blew space (T2). When T1-T2≥1℃, the air volume of the indoor unit 40 is increased to lower the temperature in the sheltered space, making it cooler for users in that space. Of course, under extreme conditions, when the indoor temperature drops to the set range, the air outlet direction of the indoor unit 40 can be controlled to turn towards the wall to avoid cold air blowing directly on people. In heating mode, every 10 minutes, the indoor unit 40 adjusts its air outlet to avoid or face people (depending on the user's settings), detects the temperature in the sheltered space (T1) and the temperature in the directly blew space (T2). When T2-T1≥1℃, the air volume of the indoor unit 40 is increased to increase the temperature in the sheltered space, thus making the heating effect more uniform throughout the room.

[0061] During the operation of the vertical air conditioner indoor unit 40, a safety distance of 2 meters is set. When the anti-collision sensor (e.g., infrared scanner) detects that the distance L from the specific location of a person to the center of the vertical air conditioner indoor unit 40 is ≤ 2m, the universal swivel wheel 23 is controlled to stop moving, and the safety anti-tipping mode is locked and activated to prevent the vertical air conditioner indoor unit 40 from tipping over and hitting people. For household cleaning work, the height of the vertical air conditioner indoor unit 40 can be adjusted by controlling the lifting structure 30 with one button to remotely adjust the height, which facilitates thorough cleaning under the support base 10.

[0062] The movable support base 10 can be used for split-type indoor units. The support base 10 can be made of lightweight and high-strength materials to serve as a support base.

[0063] The power transmission path of the rotating wheel structure 20 is as follows: the central controller sends a control signal → single-phase motor (drive motor 21) → reducer (part of the transmission unit 22) → gear set (part of the transmission unit 22) → transmission shaft (part of the transmission unit 22) → universal wheel 23 to achieve automatic movement; the reducer converts high speed and low torque into low speed and high torque through the gear transmission ratio, so that the support base 10 can move smoothly and powerfully, increasing the stability of the system; the limit structure includes a limit switch set on the ground, which is used to detect the position of the vertical air conditioner indoor unit 40 in real time and limit the movement range of the support base 10; in actual use, the position of the limit switch can be flexibly set according to the user's usage habits. The limit switch establishes a virtual constraint range in the indoor space through the deployment of sensors, which restricts the vertical air conditioner chassis assembly to move only within the virtual constraint space; of course, the limit structure may also include a restraining rope, which establishes a physical constraint range in the indoor space, which restricts the vertical air conditioner chassis assembly to move only within the physical constraint space.

[0064] The vertical air conditioner chassis component proposed in this application, when used in conjunction with the vertical air conditioner indoor unit 40, significantly improves the comfort and safety of using the vertical air conditioner indoor unit 40. Through the intelligent design of the vertical air conditioner chassis component, it not only solves the problem of cold air blowing directly on the human body, but also greatly facilitates household cleaning. The four-wheel design on the support base 10 and the 360° rotation capability of the universal casters 23 enable the vertical air conditioner indoor unit 40 to move flexibly indoors, avoiding direct cold air blowing on the human body. At the same time, the lifting structure 30 built into the support base 10 and the automatic locking mechanism of the universal casters 23 ensure the stability and safety of the vertical air conditioner indoor unit 40 during movement and cleaning. The combination of infrared sensors and a central controller enables precise human body position recognition and air outlet angle adjustment. In actual use, the avoidance rate can reach 99%, significantly improving the uniformity and comfort of the air outlet of the vertical air conditioner indoor unit 40. In addition, when a large temperature difference is detected in a local area of ​​the room, the central controller can automatically adjust the fan speed to ensure a balanced temperature throughout the room, thereby improving the overall performance and user experience of the vertical air conditioner indoor unit 40.

[0065] In summary, this invention provides a vertical air conditioner chassis assembly, a vertical air conditioner, and a method for preventing direct airflow. By using a supporting base 10, multiple rotating wheel structures 20, and multiple lifting structures 30 working together, this invention achieves the support, movement, rotation, and lifting adjustment of the vertical air conditioner indoor unit 40 with a simple structure. This allows the air outlet of the vertical air conditioner indoor unit 40 to have freedom of movement, rotation, and lifting, so that the air outlet angle of the vertical air conditioner indoor unit 40 is no longer limited by the original air guiding structure. Structurally, it achieves airflow avoidance for the human body, especially preventing cold air from directly blowing on the human body in cooling mode, thus improving user comfort. By setting up the lifting structures 30, the supporting base 10 is positioned relative to the ground... The increased spacing facilitates subsequent cleaning under the support base 10; the rotating wheel structure 20 allows the support base 10 to be moved away from its long-term location, making it easier for users to thoroughly clean the area. The vertical air conditioner chassis assembly proposed in this invention can efficiently work with the vertical air conditioner indoor unit 40, ensuring that the indoor unit 40 does not have to sacrifice some of its cooling function or room comfort to avoid direct cold air blowing on users. This invention has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of existing vertical air conditioners being unable to move or rotate, resulting in direct cold air blowing on users and difficulties in cleaning the area where the vertical air conditioner is located. It is suitable for large-scale promotion and use.
