[0002] In practical applications, various accidents or human factors can cause floor-standing air conditioners to tip over, leading to alarming electrical safety incidents. For example, if a floor-standing air conditioner falls, its air outlet and return air inlet may become blocked, causing a rapid decrease in airflow. This can result in ineffective heat dissipation from the electric heater, causing abnormal internal temperature rise and potentially leading to spontaneous combustion, posing a risk to personal injury and property damage. Therefore, mitigating the electrical safety hazards caused by floor-standing air conditioners tipping over is an urgent problem to be solved. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a method, device and air conditioner for safety protection control of air conditioner tilt, so as to alleviate the above-mentioned technical problems, avoid electrical safety accidents caused by air conditioner falling, and thus ensure the personal and property safety of users.

When the air conditioner is operating in heating mode and the electric auxiliary heating is turned on, it first determines whether the air conditioner has fallen based on the tilt angle and a preset angle threshold. If it has fallen, it determines whether the air conditioner has experienced an abnormal malfunction based on the first current value before the fall and the second current value after the fall. When an abnormal malfunction occurs, the electric auxiliary heating is disconnected to provide electrical safety protection for the air conditioner, avoiding electrical safety accidents caused by the air conditioner falling, thereby ensuring the personal and property safety of users.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions 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, not all embodiments. 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.

[0025] To address the issue of existing methods lacking relevant electrical safety measures for electrical safety accidents caused by air conditioners falling over, the present invention provides an air conditioner tilt safety protection control method, device, and air conditioner. When the air conditioner is operating in heating mode and the electric auxiliary heating is activated, it first determines whether the air conditioner has fallen based on the tilt angle and a preset angle threshold. If it has fallen, it determines whether the air conditioner has experienced an abnormal malfunction based on the first current value before the fall and the second current value after the fall. When an abnormal malfunction occurs, it disconnects the power to the electric auxiliary heating to provide electrical safety protection for the air conditioner, avoiding electrical safety accidents caused by the air conditioner falling over, thereby ensuring the personal and property safety of users.

[0026] To facilitate understanding of this embodiment, the air conditioner tilt safety protection control method provided by this invention will be described in detail below. It should be noted that the air conditioner in this embodiment is preferably a floor-standing air conditioner or a seated air conditioner.

[0027] Example 1:

[0028] This invention provides a method for controlling the tilt safety of an air conditioner, such as... Figure 1 As shown, the method includes the following steps:

[0029] Step S102: When the air conditioner is running in heating mode and the electric auxiliary heating is turned on, the tilt angle and the first current value of the air conditioner are obtained in real time.

[0030] The first current value I1 characterizes the motor current during the air conditioner's heating operation. Since the motor drives the fan, this motor current value can also be called the fan current value. The tilt angle characterizes the angle between the air conditioner's center of gravity and the vertical direction. In practical applications, a gyroscope or other angular motion measuring device can be installed inside the air conditioner to measure the tilt angle in real time. This allows for the determination of the degree of tilt, which includes a first tilt state, a second tilt state, and a third tilt state. The first tilt state characterizes the air conditioner as tilted but not yet tipped over; the second tilt state characterizes the air conditioner as being on the verge of tipping over (i.e., about to tip over but not yet); and the third tilt state characterizes the air conditioner as tipped over. Therefore, the degree of tilt can be determined in real time based on the air conditioner's tilt angle, enabling timely electrical safety protection in case of a tipping over, thus preventing electrical accidents caused by the air conditioner falling.

[0031] Step S104: Determine whether the air conditioner has fallen based on the tilt angle and the preset angle threshold;

[0032] Specifically, when the tilt angle is less than a preset angle threshold, the air conditioner is in a first tilt state; when the tilt angle is equal to the preset angle threshold, the air conditioner is in a second tilt state; and when the tilt angle is greater than the preset angle threshold, the air conditioner is in a third tilt state. Since this embodiment of the invention focuses on the safety protection of the air conditioner after it has fallen, in this embodiment, if the tilt angle of the air conditioner is greater than the preset angle threshold, it is determined that the air conditioner has fallen; if the tilt angle is not greater than the preset angle threshold, it is determined that the air conditioner has not fallen. This facilitates the quick determination of whether the air conditioner has fallen based on the tilt angle and the preset angle threshold, so as to provide timely safety protection for the air conditioner after a fall.

[0033] It should be noted that, according to the latest IEC (International Electrotechnical Commission) standard, in order to further improve the requirements for electrical safety, the tilt angle of the standing air conditioner is judged. When the tilt angle of the standing air conditioner is ≥15°, protective measures are required. That is, the above-mentioned preset angle threshold is preferably 15°. The specific value can be adjusted according to the actual situation. Also, the corresponding preset angle threshold may be different for different models of air conditioners.

[0034] Step S106: If yes, obtain the second current value of the air conditioner;

[0035] When an air conditioner falls over, the second current value I2 of the air conditioner is obtained. This second current value I2 is used to characterize the motor current value after the air conditioner falls over. Therefore, the first current value I1 and the second current value I2 are used to represent the motor current value before and after the air conditioner falls over, respectively. Based on the motor current value before and after the fall, it is determined whether an abnormal fault has occurred after the air conditioner falls over. If an abnormal fault occurs, timely safety protection is provided for the air conditioner after the fall, thus avoiding electrical safety accidents caused by the air conditioner falling over.

[0036] Step S108: Determine whether the air conditioner has malfunctioned based on the first current value and the second current value;

[0037] Specifically, when an air conditioner tilts and falls, if it falls headfirst, the air outlet will be blocked, affecting its performance and reliability. If it falls backward, the return air outlet will be blocked, also affecting performance and reliability. If it tilts but the air outlet and return air outlet are not blocked, the impact on performance and reliability is minimal, and air conditioning can still be performed. Furthermore, considering that a tilted fall might damage the motor, preventing the electric auxiliary heating from dissipating heat properly, the first and second current values ​​before and after the fall can be used to determine if the air conditioner has malfunctioned, thus preventing electrical safety accidents caused by the fall.

[0038] Among them, abnormal faults include first fault and second fault. The first fault is used to characterize the fault that the electric auxiliary heating cannot dissipate heat normally, and the second fault is used to characterize the fault that the air outlet and / or return air outlet of the air conditioner is blocked. At this time, regardless of whether the fallen air conditioner is experiencing the first fault or the second fault, the air conditioner must be equipped with electrical safety protection to avoid electrical safety accidents caused by the fall.

[0039] Step S110: If yes, disconnect the power to the electric auxiliary heating to provide electrical safety protection for the air conditioner.

[0040] The air conditioner tilt safety protection control method provided in this embodiment of the invention, when the air conditioner is running in heating mode and the electric auxiliary heating is turned on, firstly determines whether the air conditioner has fallen based on the tilt angle of the air conditioner and a preset angle threshold. If it has fallen, it determines whether the air conditioner has experienced an abnormal malfunction based on the first current value before the fall and the second current value after the fall. When an abnormal malfunction occurs, it cuts off the power to the electric auxiliary heating to provide electrical safety protection for the air conditioner, avoiding electrical safety accidents caused by the air conditioner falling, thereby ensuring the personal and property safety of users.

[0041] In one embodiment, the process of determining whether the air conditioner has an abnormal fault based on the first current value and the second current value is as follows: calculate the ratio of the second current value to the first current value; determine whether the air conditioner has an abnormal fault based on the ratio and a preset threshold.

[0042] Specifically, firstly, the ratio k = I2 / I1 is calculated based on the first current value and the second current value, and then the air conditioner is judged to have an abnormal malfunction based on the ratio k and a preset threshold. The preset threshold includes a first threshold A1 and a second threshold A2, and the first threshold is less than the second threshold, i.e., A1 < A2. Here, A1 is preferably 0.98, and A2 is preferably 1.02. The specific values ​​of A1 and A2 can be adaptively adjusted according to actual conditions, and this embodiment of the invention does not impose any limitations.

[0043] The following are methods for determining whether an air conditioner has malfunctioned:

[0044] (1) If the ratio is not greater than the second threshold and is not less than the first threshold, it is determined that the air conditioner has not experienced any abnormal malfunction; that is, when A1≤k≤A2, it means that although the air conditioner has fallen, the air outlet and return air outlet are not blocked, and the electric auxiliary heating is dissipating heat normally. It is determined that the air conditioner has not experienced any abnormal malfunction. At this time, the air conditioner is controlled to continue to operate in the heating mode to regulate the indoor environment.

[0045] (2) If the ratio is less than the first threshold, the air conditioner is determined to have the first fault. That is, when k < A1, it means that the fan power is reduced, the motor is damaged, the second current value is reduced, and at this time, the electric auxiliary heating cannot dissipate heat normally. That is, the air conditioner has fallen and an abnormal fault has occurred. The abnormal fault is the first fault.

[0046] (3) If the ratio is greater than the second threshold, the air conditioner is determined to have a second fault. That is, when k > A2, it means that after the air conditioner falls, the fan power increases and the motor is damaged. At this time, the air outlet and / or return air outlet are blocked, which leads to an increase in the motor load. That is, the air conditioner falls and an abnormal fault occurs. The abnormal fault is the second fault.

[0047] Therefore, by analyzing the motor current values ​​before and after the air conditioner falls, it is possible to quickly determine whether an abnormal malfunction has occurred after the fall. In this way, if an abnormal malfunction occurs, timely safety protection can be provided for the air conditioner after it falls, thus avoiding electrical safety accidents caused by the fall.

[0048] In one embodiment, the method further includes: if the air conditioner does not fall, controlling the air conditioner to continue operating in heating mode to meet the user's heating needs, thereby ensuring the user's air conditioning comfort.

[0049] Example 2:

[0050] To facilitate understanding, a 3P square air conditioner is used as an example. This square air conditioner has a built-in gyroscope and a 50W DC motor, with a 2000W electric auxiliary heating. Based on the air conditioner's volume and center of gravity, a tilt threshold, i.e., a preset angle threshold, is calculated and recorded in the controller. In practical applications, the gyroscope is used to detect the tilt angle β of the air conditioner in real time, where β is the angle between the air conditioner's center of gravity and the vertical direction. For example, the tilt angle at each moment is β1, β2…β… n , here β n This indicates the tilt angle at the current moment. In addition, the motor current value is recorded simultaneously in real time. Assuming the fan speed is at high power, the current motor current value (i.e., the first current value is I) is... A This paper describes the tilt safety protection control process of the square air conditioner based on the current moment.

[0051] Based on the above method embodiments, this invention proposes another air conditioner tilt safety protection control method, which focuses on describing the safety protection control process when a square air conditioner tilts for some reason. For example... Figure 2 As shown, the method includes the following steps:

[0052] Step S202: The cabinet air conditioner operates in heating mode and the electric auxiliary heating is turned on;

[0053] Step S204: Obtain the tilt angle β at the current moment. n ;

[0054] Step S206, determine β n ≤α; that is, determine whether the tilt angle at the current moment is not greater than the preset angle threshold. If yes, return to step S202 and control the air conditioner to continue to operate in heating mode to perform air conditioning; if no, execute step S208.

[0055] Step S208: Obtain the motor current value I after the square air conditioner falls over. B ;

[0056] Step S210, determine whether I is satisfied. B I A <0.98; if yes, proceed to step S212; otherwise, proceed to step S214.

[0057] Step S212, the cabinet air conditioner experiences its first fault; that is, at this time the fan power decreases, the motor is damaged, the current value decreases, and the electric auxiliary heating cannot dissipate heat normally.

[0058] Step S214, determine whether I is satisfied. B I A>1.02; if yes, proceed to step S216; otherwise, proceed to step S218.

[0059] Step S216, the cabinet air conditioner experiences a second malfunction; that is, after the air conditioner falls over, the fan power increases, the motor is damaged, and the air outlet and / or return air outlet become blocked.

[0060] Step S218: Control the cabinet air conditioner to continue operating in heating mode; that is, although the air conditioner has fallen, the air outlet and return air outlet are not blocked, and the electric auxiliary heating is dissipating heat normally. It is determined that the air conditioner has not experienced any abnormal malfunction. At this time, control the air conditioner to continue operating in heating mode to regulate the indoor air.

[0061] Step S220: Power off the electric auxiliary heating.

[0062] In summary, the air conditioner tilt safety protection control method provided in this embodiment of the invention determines whether the air conditioner has fallen when it tilts, based on the tilt angle. If it has fallen, it determines whether an abnormal fault has occurred in the air conditioner based on the motor current values ​​before and after the fall. If no abnormal fault has occurred, the air conditioner continues to operate in heating mode to ensure the user's heating needs. If an abnormal fault has occurred, the electric auxiliary heating is disconnected to provide electrical safety protection for the air conditioner, avoiding electrical safety accidents caused by the air conditioner falling, thereby ensuring the personal and property safety of the user.

[0066] The first judgment module 32 is used to determine whether the air conditioner has fallen based on the tilt angle and a preset angle threshold.

[0067] The second acquisition module 33 is used to acquire the second current value of the air conditioner if the condition is true; wherein the second current value is used to characterize the motor current value after the air conditioner falls over.

[0068] The second judgment module 34 is used to determine whether the air conditioner has an abnormal fault based on the first current value and the second current value; wherein, the abnormal fault includes a first fault and a second fault, the first fault is used to characterize the fault that the electric auxiliary heating cannot dissipate heat normally, and the second fault is used to characterize the fault that the air outlet and / or return air outlet of the air conditioner is blocked.
