Description

Technical Field

[0001] This invention relates to the field of household appliances technology, and in particular to a balance control method and device for tower appliances, a tower fan, and a storage medium. Background Technology

[0002] In today's society, people's needs for home decoration space layout largely favor household appliances with small footprints and compact sizes, such as tower fans and tower heaters. To further reduce floor space and size, manufacturers have developed appliances with increasingly elongated designs. Tower appliances are often less stable than traditional cabinet appliances, making them more prone to tipping over and breaking. To ensure the stability of tower appliances, current technology typically uses counterweights to maintain balance and control.

[0003] However, excessive counterweights significantly increase the overall weight of the device, making packaging and transportation more difficult and incurring substantial additional costs. Furthermore, the added weight can cause considerable inconvenience for users during transport. Therefore, current technology, which relies solely on counterweights to maintain stability, not only increases overall weight and product cost, leading to a poor user experience, but also poses a risk of accidental tipping, further exacerbating damage if the appliance falls over. Summary of the Invention

[0004] This invention proposes a balance control method and device for tower-type electrical appliances, a tower fan, and a storage medium to solve the technical problems of existing technologies that only use the addition of counterweights to maintain the stability of the whole machine, which has the technical defects of increasing the weight of the whole machine and the product cost, resulting in a poor user experience, and also poses the risk of accidental tipping, further aggravating the damage to the appliance after tipping.

[0005] In one aspect, the present invention provides a method for balancing a tower-type electrical appliance, the method comprising:

[0006] Obtain the center of gravity offset data of the tower appliance, which includes the azimuth angle of the current center of gravity offset relative to the initial position, the tilting direction of the body, and the tilting angle relative to the horizontal position.

[0007] Determine whether the tilting angle meets the activation conditions of the tower electrical balance function;

[0008] When the tilting angle meets the activation conditions of the tower appliance's balancing function, the counterweight of the tower appliance is moved according to the azimuth angle of the center of gravity offset from the initial position and the tilting direction of the machine body, so as to achieve the balancing control of the tower appliance.

[0009] Furthermore, determining whether the tilting angle meets the activation conditions of the tower electrical balance function includes:

[0010] Determine whether the tilting angle is greater than the preset safe tilting angle;

[0011] When the tilting angle is greater than the preset safe tilting angle, it is determined that the tilting angle meets the activation conditions of the tower electrical balance function.

[0012] Furthermore, before controlling the movement of the counterweight of the tower appliance based on the azimuth angle of the center of gravity offset relative to the initial position and the tilting direction of the fuselage, the method further includes:

[0013] Obtain the angle difference between the tilting angle and the safe tilting angle;

[0014] The moving speed of the counterweight is determined based on the angle threshold range to which the angle difference belongs.

[0015] Furthermore, the counterweight of the tower electrical system is moved according to the azimuth angle of the center of gravity offset from the initial position and the tilting direction of the fuselage, including:

[0016] The direction and angle of rotation of the counterweight to be adjusted are determined based on the azimuth angle of the center of gravity offset from the initial position, the tilting direction of the fuselage, and the actual azimuth angle of the counterweight.

[0017] The counterweight is controlled to move according to the rotation direction and rotation angle.

[0018] Furthermore, based on the azimuth angle of the center of gravity offset from the initial position, the tilting direction of the fuselage, and the actual azimuth angle of the counterweight, the rotation direction and angle to be adjusted of the counterweight are determined, including:

[0019] When the fuselage tilts in a negative direction, the first rotation angle to be adjusted for the counterweight is determined according to the first calculation model, which is φ1=θ-θ0;

[0020] The counterweight is controlled to rotate in the positive direction according to the first rotation angle;

[0021] When the fuselage tilts in the positive direction, the second rotation angle to be adjusted of the counterweight is determined according to the second calculation model, which is φ2=180-θ+θ0;

[0022] The counterweight is controlled to rotate in the positive direction according to the second rotation angle;

[0023] Where θ is the azimuth angle of the center of gravity relative to the initial position, θ0 is the actual azimuth angle of the counterweight, and the initial value of θ0 is 0.

[0024] Further, controlling the counterweight to move according to the rotation direction and rotation angle includes:

[0025] The movement time of the counterweight to the opposite azimuth angle of the azimuth angle offset from the initial position is calculated based on the rotation direction, rotation angle, and moving speed of the counterweight.

[0026] Based on the motion time, the counterweight is controlled to move in the rotation direction and at the moving speed.

[0027] Furthermore, after controlling the counterweight to move according to the rotation direction and moving speed based on the motion time, the method further includes:

[0028] Detect whether the counterweight has moved to the opposite azimuth angle of the azimuth angle of the center of gravity relative to the initial position;

[0029] If the counterweight has moved to the opposite azimuth angle of the azimuth angle of the center of gravity relative to the initial position, update the initial azimuth angle of the counterweight to the opposite azimuth angle.

[0030] If the counterweight does not move to the opposite azimuth angle of the center of gravity relative to the initial position, a balance function failure signal is issued to prompt the user to perform maintenance.

[0031] In another aspect of the present invention, a balance control device for a tower-type electrical appliance is provided, the device comprising:

[0032] The acquisition module is used to acquire the center of gravity offset data of the tower appliance. The center of gravity offset data includes the azimuth angle of the current center of gravity offset relative to the initial position, the tilting direction of the body, and the tilting angle relative to the horizontal position.

[0033] The judgment module is used to determine whether the tilting angle meets the activation conditions of the tower electrical balance function;

[0034] The control module is used to control the counterweight of the tower appliance to move according to the azimuth angle of the center of gravity offset relative to the initial position and the tilting direction of the machine body when the tilting angle meets the starting conditions of the tower appliance's balancing function, so as to achieve the balancing control of the tower appliance.

[0035] Furthermore, the present invention also proposes a tower fan, including a fan body and a controller. The controller includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the balance control method for the tower electric appliance as described above.

[0036] Furthermore, the fan body includes a casing, a center of gravity monitoring sensor, and a chassis assembly;

[0037] The center of gravity monitoring sensor is located at the center of gravity of the machine body and is used to monitor the center of gravity offset data of the tower fan and send it to the controller;

[0038] The chassis assembly includes a chassis, a counterweight and a motor assembly disposed on the chassis. The motor assembly is used to control the counterweight to move according to the control instructions of the controller, so as to achieve balance control of the machine body.

[0039] Furthermore, the present invention also proposes a computer-readable storage medium storing a computer program thereon, which, when controlled by a processor, implements the steps of the balancing control method for the tower appliance as described above.

[0040] This invention discloses a method and device for balancing a tower appliance, a tower fan, and a storage medium. By acquiring the center-of-gravity offset data of the tower appliance, including the azimuth angle of the current center-of-gravity offset relative to the initial position, the tilting direction of the appliance, and the tilting angle relative to the horizontal position, the method controls the movement of the counterweight of the tower appliance based on the azimuth angle of the center-of-gravity offset relative to the initial position and the tilting direction of the appliance when the tilting angle meets the activation conditions of the tower appliance's balancing function. This invention effectively achieves the effect of balancing the entire appliance by combining actual center-of-gravity data with initial center-of-gravity data to control the movement of the counterweight, without increasing the weight of the counterweight, thus avoiding adverse effects on packaging, transportation, and user operation caused by excessive counterweight weight.

[0041] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below. Attached Figure Description

The drawings are only used to illustrate preferred embodiments and are not intended to limit the present invention.

[0044] Figure 2 This is a flowchart illustrating a balancing control method for a tower-type electrical appliance according to an embodiment of the present invention.

[0045] Figure 3 This is a structural block diagram of a tower-type electrical appliance balance control device according to an embodiment of the present invention. Detailed Implementation

[0046] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Obviously, the described embodiments are only a portion, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0047] Figure 1 A flowchart illustrating a balancing control method for a tower-type electrical appliance according to an embodiment of the present invention is shown. Figure 1 As shown, the balancing control method for tower electrical equipment proposed in this embodiment of the invention includes the following steps:

[0048] S11. Obtain the center of gravity offset data of the tower appliance, wherein the center of gravity offset data includes the azimuth angle of the current center of gravity offset relative to the initial position, the tilting direction of the body, and the tilting angle relative to the horizontal position.

[0049] S12. Determine whether the tilting angle meets the starting conditions of the tower electrical balance function.

[0050] In this embodiment of the invention, determining whether the tilting angle meets the activation conditions of the tower electrical appliance balancing function includes: determining whether the tilting angle is greater than a preset safe tilting angle; when the tilting angle is greater than the preset safe tilting angle, determining that the tilting angle meets the activation conditions of the tower electrical appliance balancing function; when the tilting angle is less than the preset safe tilting angle, not activating the balancing function.

[0051] It is understood that when the tilt angle is greater than the preset safe tilt angle, it indicates a large tilt amplitude. If the balance control function is not activated, the machine body will face tipping over. Therefore, setting a tilt angle greater than the preset safe tilt angle is set as the activation condition for the tower appliance's balance function to activate the balance control function and prevent the machine body from tipping over. When the tilt angle is less than the preset safe tilt angle, it indicates a small tilt amplitude, the machine body is in a stable state, and there is no immediate risk of tipping over. Therefore, it is not necessary to activate the balance function at this time. The preset safe tilt angle is determined through repeated experiments based on the machine body weight and center of gravity position of a specific model. In the experimental tests, a specific model can be freely selected, and its machine body weight and center of gravity position can be obtained to determine the preset safe tilt angle. This invention does not impose specific limitations on this.

[0052] S13. When the tilting angle meets the activation conditions of the tower electrical appliance's balancing function, the counterweight of the tower electrical appliance is moved according to the azimuth angle of the center of gravity offset from the initial position and the tilting direction of the machine body, so as to achieve the balancing control of the tower electrical appliance.

[0053] In this embodiment of the invention, controlling the movement of the counterweight of the tower appliance based on the azimuth angle of the center of gravity offset from the initial position and the tilting direction of the machine body includes: determining the rotation direction and rotation angle of the counterweight to be adjusted based on the azimuth angle of the center of gravity offset from the initial position, the tilting direction of the machine body, and the actual azimuth angle of the counterweight; and controlling the counterweight to move according to the rotation direction and rotation angle. In practical applications, the tilting direction of the machine body can be freely defined as a positive or negative direction based on the actual tilting direction of the machine body. This invention does not specifically limit the specific positions of the positive and / or negative directions.

[0054] It is understood that the target azimuth angle of the rotation direction to be adjusted of the counterweight is the opposite azimuth angle of the azimuth angle of the center of gravity relative to the initial position. When the center of gravity shifts relative to the initial position, controlling the counterweight to move to the opposite azimuth angle of the azimuth angle of the center of gravity relative to the initial position can achieve the balance of the machine body, ensure the stability of the whole machine, and thus achieve the purpose of effectively balancing and controlling the whole machine.

[0055] In this embodiment of the invention, determining the rotation direction and rotation angle of the counterweight block to be adjusted based on the azimuth angle of the center of gravity offset relative to the initial position, the tilting direction of the fuselage, and the actual azimuth angle of the counterweight block includes: when the tilting direction of the fuselage is negative, determining the first rotation angle of the counterweight block to be adjusted according to a first calculation model, the first calculation model being φ1=θ-θ0, and controlling the counterweight block to rotate in the positive direction according to the first rotation angle; when the tilting direction of the fuselage is positive, determining the second rotation angle of the counterweight block to be adjusted according to a second calculation model, the second calculation model being φ2=180-θ+θ0, and controlling the counterweight block to rotate in the positive direction according to the second rotation angle.

[0056] Where θ is the azimuth angle of the center of gravity relative to the initial position, θ0 is the actual azimuth angle of the counterweight, and the initial value of θ0 is 0.

[0057] It is understood that the azimuth angle θ of the center of gravity offset relative to the initial position is formed by the intersection of the extension line of the center of gravity point on the horizontal plane projected from the actual center of gravity position after the detected offset, and the extension line of the initial position of the center of gravity on the horizontal plane. In this embodiment, the initial value of the actual azimuth angle θ0 of the counterweight can be 0. After the counterweight moves according to the rotation direction and rotation angle and reaches the target azimuth angle, the initial value θ0 = 0 of the actual azimuth angle of the counterweight is updated to θ0 = the actual azimuth angle of the counterweight after the movement. The center of gravity position can be calculated based on the weight and volume of the whole machine, and this invention does not specifically limit it.

[0058] In this embodiment of the invention, when the tilting direction of the machine body is negative, the counterweight is controlled to rotate in the positive direction according to the first rotation angle to be adjusted calculated by the first calculation model φ1=θ-θ0, which enables the counterweight to reach the opposite azimuth angle of the center of gravity relative to the initial position within the shortest moving distance; when the tilting direction of the machine body is positive, the counterweight is controlled to rotate in the positive direction according to the second rotation angle to be adjusted calculated by the second calculation model φ2=180-θ+θ0, which enables the counterweight to reach the opposite azimuth angle of the center of gravity relative to the initial position within the shortest moving distance, thereby realizing the balance control of the whole machine and shortening the time for the balance function to perform balance control.

[0059] The present invention proposes a balance control method for a tower appliance. By monitoring the center of gravity offset data of the tower appliance in real time and using a pre-set balance function, the method controls the movement of the counterweight of the tower appliance based on the difference between the monitored actual center of gravity data and the initial center of gravity data. This effectively achieves the effect of balancing the entire machine without increasing the weight of the counterweight, thus avoiding adverse effects on the packaging and transportation process and the user's use due to excessive counterweight weight.

[0060] In this embodiment of the invention, before controlling the movement of the counterweight of the tower appliance based on the azimuth angle of the center of gravity offset from the initial position and the tilting direction of the fuselage, the method further includes: obtaining the angle difference between the tilting angle and the safe tilting angle; and determining the moving speed of the counterweight based on the angle threshold range to which the angle difference belongs. The moving speed of the counterweight is determined based on the rotational speed of the motor.

[0061] Understandably, in practical applications of tower appliance balance control, different balance control strategies can be adopted depending on the different tilt angle ranges of the machine body. In this embodiment, based on the angle threshold range to which the angle difference between the machine body's tilt angle and the safe tilt angle belongs, the motor speed corresponding to the angle threshold range is selected to determine the moving speed of the counterweight, thereby achieving balance control for different tilt states. Within a fixed timeframe during which the machine body tilts, the larger the tilt angle, the higher the motor speed is used to control the movement of the counterweight of the tower appliance, preventing the entire machine from tipping over and being damaged.

[0062] Figure 2 A detailed flowchart of a balancing control method for a tower-type electrical appliance according to an embodiment of the present invention is shown. Figure 2 As shown, in a specific embodiment, the fuselage tilt angle can be represented as α, and the safe tilt angle can be represented as β. The angle threshold range of α-β can be set as follows: First angle threshold range: 0 < α-β < 4. When the angle threshold range of α-β is within the first threshold range, the fuselage tilt angle is between 0 and 3 degrees. At this time, the control motor drives the counterweight to move using a first speed v corresponding to the first threshold range. Second angle threshold range: 4 < α-β < α-β < 7. When the angle threshold range of α-β is within the second threshold range, the fuselage tilt angle is between 3 and 6 degrees. At this time, the control motor drives the counterweight to move using a second speed 2v corresponding to the second threshold range. Third angle threshold range: 7 < α-β < 11. When the angle threshold range of α-β is within the third threshold range, the fuselage tilt angle is between 6 and 10 degrees. At this time, the control motor drives the counterweight to move using a third speed corresponding to the third threshold range. The third speed can be set to 2.5v to 3v. The fourth angle threshold range: α-β > 11. When the angle threshold range to which α-β belongs is the fourth threshold range, the tilt angle of the unit exceeds the range of balance control, and an alarm operation is executed. This can be by emitting an alarm sound to remind the user that the tower appliance is at risk of tipping over. The angle threshold range is set based on the overall balance control state of a specific model selected during multiple experiments. In practical applications, specific models and experimental testing methods can be freely selected to determine the angle threshold range; this invention does not impose specific limitations on this.

[0063] Understandably, when α-β>11, it indicates that the center of gravity has shifted significantly relative to its initial position. The moving counterweight can no longer automatically control the machine to restore balance. The alarm sound can remind the user that the risk of the tower appliance tipping over is too high and the whole machine is in an unstable state. This allows the user to take timely measures to balance the tower appliance, improve stability, prevent the machine from tipping over and breaking, and further improve the user's experience with the tower appliance.

[0064] In this embodiment of the invention, after determining the moving speed of the counterweight, the movement time of the counterweight to the opposite azimuth angle of the offset angle of the center of gravity relative to the initial position is calculated based on the rotation direction, rotation angle, and moving speed of the counterweight. Based on the movement time, the counterweight is controlled to move according to the rotation direction and moving speed. The movement time is the time the motor is energized. The motor energizing time is determined through repeated experiments. During the experiment, it can be obtained by testing the chassis size, counterweight size, rotation angle, and the overall balance of the machine. The overall balance of the machine can be judged based on the magnitude of the azimuth angle offset of the center of gravity relative to the initial position. The motor energizing time can be set to 1–5 seconds, meaning the movement time can be set to 1–5 seconds; this invention does not impose specific limitations on this.

[0065] In a specific embodiment, the movement time can be represented as T, the tilting direction of the fuselage can be represented as x, the tilting angle of the fuselage can be represented as α, and the safe tilting angle can be represented as β. When x < 0, it indicates that the tilting direction of the fuselage is negative. The first rotation angle φ1 to be adjusted of the counterweight is calculated according to the first calculation model φ1 = θ - θ0. The moving speed V1 of the counterweight is determined based on the motor speed v corresponding to the angle threshold range of α-β. The counterweight is controlled to move in the positive direction by the first rotation angle φ1 based on the movement time T1 and the moving speed V1. When x > 0, it indicates that the tilting direction of the fuselage is positive. The second rotation angle φ2 to be adjusted of the counterweight is calculated according to the second calculation model φ2 = 180 - θ + θ0. The moving speed V2 of the counterweight is determined based on the motor speed v corresponding to the angle threshold range of α-β. The counterweight is controlled to move in the positive direction by the second rotation angle φ2 based on the movement time T2 and the moving speed V2.

[0066] In this embodiment of the invention, after controlling the counterweight to move according to the rotation direction and moving speed based on the motion time, the method further includes: detecting whether the counterweight has moved to the opposite azimuth angle of the azimuth angle offset from the initial position of the center of gravity; if the counterweight has moved to the opposite azimuth angle of the azimuth angle offset from the initial position of the center of gravity, updating the initial azimuth angle of the counterweight to the opposite azimuth angle, and ending the balance control process; if the counterweight has not moved to the opposite azimuth angle of the azimuth angle offset from the initial position of the center of gravity, issuing a balance function failure signal to prompt the user to perform maintenance. The issuance of the balance function failure signal can be implemented by a signal code. The balance function failure signal indicates that the balance function of the balance module has malfunctioned. At this time, the user needs to check the appliance or contact after-sales service for appliance repair.

[0067] It should be noted that in practical applications, after each movement of the counterweight according to the rotation direction and moving speed based on the movement time, the position angle of the counterweight can be detected, without the need to monitor the position angle of the counterweight in real time, so as to avoid wasting resources.

[0068] For the sake of simplicity, the method embodiments are described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.

[0069] Figure 3 This is a structural block diagram of a balancing control device for a tower-type electrical appliance according to an embodiment of the present invention. Figure 3 As shown, the device includes a functional module for implementing the balance control method for the tower electrical appliance as described in the above embodiment:

[0070] Specifically, it includes: an acquisition module 201, used to acquire the center of gravity offset data of the tower appliance, the center of gravity offset data including the azimuth angle of the current center of gravity offset relative to the initial position, the tilting direction of the body, and the tilting angle relative to the horizontal position.

[0071] The judgment module 202 is used to determine whether the tilting angle meets the activation conditions of the tower electrical balance function.

[0072] The control module 203 is used to control the counterweight of the tower appliance to move according to the azimuth angle of the center of gravity offset relative to the initial position and the tilting direction of the machine body when the tilting angle meets the starting conditions of the tower appliance balancing function, so as to realize the balancing control of the tower appliance.

[0073] In this embodiment of the invention, the judgment module 202 is specifically used to determine whether the tilting angle is greater than a preset safe tilting angle; when the tilting angle is greater than the preset safe tilting angle, it is determined that the tilting angle meets the starting conditions of the tower electrical balance function.

[0074] In this embodiment of the invention, the acquisition module 201 is further configured to acquire the angle difference between the tilting angle and the safe tilting angle before the counterweight of the tower appliance is moved according to the azimuth angle of the center of gravity offset relative to the initial position and the tilting direction of the body; and determine the moving speed of the counterweight according to the angle threshold range to which the angle difference belongs.

[0075] In this embodiment of the invention, the control module 203 is further configured to determine the rotation direction and rotation angle of the counterweight block to be adjusted based on the azimuth angle of the center of gravity offset relative to the initial position, the tilting direction of the fuselage, and the actual azimuth angle of the counterweight block; and control the counterweight block to move according to the rotation direction and rotation angle.

[0076] In this embodiment of the invention, the control module 203 further includes (not shown in the accompanying drawings):

[0077] A first calculation unit is used to determine the first rotation angle to be adjusted of the counterweight block according to a first calculation model when the fuselage tilts in a negative direction. The first calculation model is φ1 = θ - θ0. A first control unit is used to control the counterweight block to rotate in a positive direction according to the first rotation angle. A second calculation unit is used to determine the second rotation angle to be adjusted of the counterweight block according to a second calculation model when the fuselage tilts in a positive direction. The second calculation model is φ2 = 180 - θ + θ0. A second control unit is used to control the counterweight block to rotate in a positive direction according to the second rotation angle. Wherein, θ is the azimuth angle of the center of gravity relative to the initial position, θ0 is the actual azimuth angle of the counterweight block, and the initial value of θ0 is 0.

[0078] In this embodiment of the invention, the device further includes a detection module (not shown in the drawings), used to detect whether the counterweight has moved to the opposite azimuth angle of the azimuth angle offset from the initial position of the center of gravity; when the counterweight has moved to the opposite azimuth angle of the azimuth angle offset from the initial position of the center of gravity, the control module 203 updates the initial azimuth angle of the counterweight to the opposite azimuth angle; when the counterweight has not moved to the opposite azimuth angle of the azimuth angle offset from the initial position of the center of gravity, the control module 203 issues a balance function failure signal to prompt the user to perform maintenance.

[0079] Furthermore, embodiments of the present invention also propose a computer-readable storage medium storing a computer program thereon, which, when controlled by a processor, implements the steps of the balancing control method for the tower appliance as described above.

[0080] In this embodiment, if the balancing control method for a tower appliance is implemented as a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, all or part of the processes in the methods of the above embodiments can also be implemented by a computer program instructing related hardware. The computer program can be stored in a computer-readable storage medium, and when controlled by a processing device, it can implement the steps of the various method embodiments described above. The computer program includes computer program code, which can be in the form of source code, object code, controllable files, or certain intermediate forms. The computer-readable medium can include: any entity or device capable of carrying the computer program code, a recording medium, a USB flash drive, a portable hard drive, a magnetic disk, an optical disk, a computer storage device, a read-only memory (ROM), a random access memory (RAM), an electrical carrier signal, a telecommunication signal, and a software distribution medium, etc. It should be noted that the content contained in the computer-readable medium may be appropriately added to or subtracted from the content as required by the legislation and patent practice in the jurisdiction. For example, in some jurisdictions, according to legislation and patent practice, the computer-readable medium may not include electrical carrier signals and telecommunication signals.

[0081] Furthermore, the present invention also proposes a tower fan, including a fan body and a controller. The controller includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the balance control method for the tower electric appliance as described above.

[0082] In this embodiment, the fan body includes a body, a center of gravity monitoring sensor, and a chassis assembly;

[0083] The center of gravity monitoring sensor is located at the center of gravity of the machine body and is used to monitor the center of gravity offset data of the tower fan and send it to the controller;

[0084] The chassis assembly includes a chassis, a counterweight and a motor assembly disposed on the chassis. The motor assembly is used to control the counterweight to move according to the control command of the controller, so as to achieve balance control of the machine body.

[0085] The center of gravity offset data includes the azimuth angle of the current center of gravity offset relative to the initial position, the tilting direction of the fuselage, and the tilting angle relative to the horizontal position.

[0086] In one specific embodiment, a pre-set offset time threshold t for the center of gravity monitoring sensor is used to adjust the monitoring sensitivity of the sensor by the controller. During the operation of the tower appliance, the time of center of gravity shift and the center of gravity shift data of the tower appliance are monitored based on the pre-set offset time threshold t, thereby improving the monitoring sensitivity of the center of gravity monitoring sensor and meeting the balance stability requirements of different models of tower appliances. The offset time threshold t can be determined based on the tilting state of the machine body in multiple experiments for a specific model, which will not be specifically described in this invention.

[0087] Understandably, the value of the pre-set offset time threshold t determines the sensitivity of the center of gravity monitoring. The smaller the t value, the shorter the time it takes for the aircraft to tip over. If the aircraft tip over and the center of gravity shifts within a very short time, it indicates that the center of gravity monitoring sensor has high sensitivity. Conversely, the larger the t value, the longer the time it takes for the aircraft to tip over. If the aircraft tip over and the center of gravity shifts within a longer time, it indicates that the center of gravity monitoring sensor has low sensitivity.

[0088] The tower fan proposed in this invention uses a center-of-gravity monitoring sensor to monitor the center-of-gravity shift data in real time. When the fan tipps over, the counterweight is moved based on the difference between the actual and initial center-of-gravity data. This allows for timely adjustment after a small angle shift, enhancing overall stability while reducing the weight of the counterweight, thus lowering packaging and transportation costs. The invention automates the balance control of the tower fan, preventing human intervention from disrupting the balance and reducing the likelihood of accidental damage, thereby improving the user experience.

[0089] This invention discloses a method and device for balancing a tower appliance, a tower fan, and a storage medium. By acquiring the center-of-gravity offset data of the tower appliance, including the azimuth angle of the current center-of-gravity offset relative to the initial position, the tilting direction of the appliance, and the tilting angle relative to the horizontal position, the method achieves balance control of the tower appliance by controlling the movement of the counterweight based on the azimuth angle of the center-of-gravity offset relative to the initial position and the tilting direction. This invention, by setting a balancing function and controlling the movement of the counterweight based on the difference between the actual and initial center-of-gravity data, effectively achieves the effect of balancing the entire appliance without increasing the weight of the counterweight, avoiding adverse effects on packaging, transportation, and user operation caused by excessive counterweight weight.
