Description

Technical Field

[0001] This invention relates to the field of portable air conditioner testing technology, and in particular to a method for detecting and processing a portable air conditioner tipping over. Background Technology

[0002] In today's world of global warming, air conditioning provides a comfortable environment for people's daily lives and work, thus becoming an indispensable appliance in every household and workplace. There are many types of air conditioners to suit different needs, such as split-type, cabinet-type, and portable air conditioners. Among them, portable air conditioners are popular with many consumers due to their small size, light weight, and ease of movement. Currently, most portable air conditioners have a rectangular or similar structure, which often leads to accidental tipping during use. If the machine cannot detect this abnormal operation, it can cause dangers such as fire or electric shock. To address the tipping problem of portable air conditioners, most systems use residual current devices (RCDs) and overheat protection for the motor and compressor, which are only basic back-end protections and cannot provide early warning of potential hazards and timely intervention.

[0003] Currently, air conditioner manufacturers do not pay enough attention to the issue of air conditioner tipping, leading to product damage and economic losses for many users due to the tipping of portable air conditioners, thus affecting user experience. Many other products incorporate anti-tipping monitoring measures. For example, Chinese invention patent CN109945836A discloses a sign tipping detection device. Its features include a main body housed within the inner cavity of a column, comprising a container, a movable obstruction, and a photoelectric sensor. The bottom center of the container has a vertically penetrating hole leading to a light transceiver unit. The outer diameter of the movable obstruction is larger than the diameter of the hole, and the movable obstruction rests on the hole within the container. The photoelectric sensor signal is connected to the electronic control system. When the column tilts more than 10° in any direction, the movable obstruction detaches from the hole, and the photoelectric sensor experiences loss of sensitivity or a delay increase exceeding a preset range. The detection device in this patent is not suitable for portable air conditioners, especially portable air conditioners with dehumidification functions. It has a complex structure, increases the floor space, cannot determine the tilt status of the product, and relevant personnel cannot obtain information about the tilt status of the product in a timely manner, so they cannot take effective measures in a timely manner. Summary of the Invention

[0004] In view of this, the present invention aims to provide a method for detecting and handling the tilting of a portable air conditioner. This method employs five symmetrically positioned sensors. A rolling element moves to the corresponding sensor under gravity to detect the tilt angle of the portable air conditioner. A detection device is installed on each of two adjacent side walls, along with an alarm device. The processing device promptly determines the tilt state of the portable air conditioner based on the received tilt information and issues different alarm messages according to different tilt states. The processing device controls the operation of the portable air conditioner through a control device. This method solves the problems of detection devices being unsuitable for portable air conditioners, especially those with dehumidification functions, having complex structures, increasing floor space, being unable to determine the tilt state of the product, and preventing relevant personnel from obtaining timely tilt information and taking effective measures.

[0005] To address the above problems, this invention provides a method for detecting and processing the tipping of a portable air conditioner, comprising:

[0006] The portable air conditioner is equipped with an information detection device, which includes a sensor. The sensor periodically detects the tilt angle of the portable air conditioner and sends the detected tilt angle information to a processing device to determine the status of the portable air conditioner.

[0007] When the processing device receives a tilt angle of 0 ≤ φ ≤ α from the portable air conditioner, it determines that the portable air conditioner is in a normal state.

[0008] When the processing device receives a tilt angle α < φ ≤ β from the portable air conditioner, it determines that the portable air conditioner is in a tilted state, and the processing device sends a first alarm command to the alarm device, and the alarm device issues a first alarm.

[0009] When the processing device receives a tilt angle φ > β from the portable air conditioner, it determines that the portable air conditioner is in a tilted state. The processing device sends a second alarm command to the alarm device, the alarm device issues a second alarm, and the processing device sends a control command to the control device, the control device controls the portable air conditioner to stop.

[0010] Where α is the first preset angle, β is the second preset angle, and 0 < α < β.

[0011] Furthermore, at least three sensors are installed inside the portable air conditioner, arranged sequentially at points A, B, and C from high to low.

[0012] The angle α between the line BC connecting the positions of the two sensors at points B and C and the horizontal direction is α;

[0013] The angle between the line AC connecting the positions of the two sensors at points A and C and the horizontal direction is β.

[0014] Furthermore, the processing device determines the tilt direction of the portable air conditioner based on the angle information detected by the sensor.

[0015] Furthermore, two sensors are also installed at points D and E inside the portable air conditioner, and the heights of the three locations, C, D, and E, increase sequentially.

[0016] The lines ABC and CDE intersect at point C.

[0017] The angle between the line DC connecting the positions of the two sensors at points D and C and the horizontal direction is α;

[0018] The angle between the line EC connecting the positions of the two sensors at points E and C and the horizontal direction is β.

[0019] Furthermore, the information detection device is composed of a channel that is sequentially connected at points A, B, C, D, and E, with a sensor installed at each of the points A, B, C, D, and E.

[0020] A rolling element is provided within the channel.

[0021] Furthermore, the channel is a U-shaped pipe.

[0022] Furthermore, the information detection device is installed on the inner wall of the wall panel of the portable air conditioner.

[0023] Furthermore, the tilting direction includes a first X-axis direction and a second X-axis direction that are opposite to each other, as well as a first Y-axis direction and a second Y-axis direction that are opposite to each other.

[0024] Furthermore, an information detection device is respectively installed on the inner sidewall of two adjacent wall panels of the portable air conditioner.

[0025] Furthermore, the sensor is an infrared sensor.

[0026] Compared with existing technologies, the mobile air conditioner tilt detection and processing method of the present invention has the following advantages:

[0027] The advantages of this technical solution lie in its use of five symmetrically positioned sensors.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] In this invention, the terms "first," "second," "upper," and "lower," etc., are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "upper," or "lower" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. Where the technical solutions of the embodiments can be combined, they are all within the scope of protection claimed by this invention.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figure 1 As shown, a method for detecting and processing the tilt of a portable air conditioner includes: an information detection device provided in the portable air conditioner, the information detection device including a sensor, the sensor periodically detecting the tilt angle of the portable air conditioner, and sending the detected tilt angle information to a processing device to determine the state of the portable air conditioner.

[0039] When the processing device receives a tilt angle of 0 ≤ φ ≤ α from the portable air conditioner, it determines that the portable air conditioner is in a normal state.

[0040] When the processing device receives a tilt angle α < φ ≤ β from the portable air conditioner, it determines that the portable air conditioner is in a tilted state, and the processing device sends a first alarm command to the alarm device, which then issues a first alarm.

[0041] When the processing device receives a tilt angle φ > β from the portable air conditioner, it determines that the portable air conditioner is in a tilted state. The processing device sends a second alarm command to the alarm device, the alarm device issues a second alarm, and the processing device sends a control command to the control device, the control device controls the portable air conditioner to stop.

[0042] Where α is the first preset angle, β is the second preset angle, and 0 < α < β.

[0043] The portable air conditioner tilt detection and processing method described in the above embodiments of the present invention uses a sensor to detect the tilt angle, and the processing device determines the tilt state of the portable air conditioner. When 0 ≤ φ ≤ α, for example, α = 30°, it is within the allowable tilt range of the portable air conditioner, and the portable air conditioner is determined to be in a normal state. For example, a small tilt caused by uneven ground allows the portable air conditioner to operate normally without affecting its various functions. When α < φ ≤ β, for example, β = 45°, the air conditioner is determined to be tilted. In this case, the air conditioner can still operate normally, but it has a tendency to tilt. If it is not straightened as soon as possible, the air conditioner will continue to tilt until it tipes over. When the processing device determines that the portable air conditioner is tilted, it sends a first alarm command to the alarm device, and the alarm device issues a first alarm. When φ > β, it is determined that the portable air conditioner is tilted, and the processing device sends a second alarm command to the alarm device, and the alarm device issues a second alarm.

[0044] As one embodiment, the alarm device uses different alarms to inform the operator of the tilted and tipped states of the portable air conditioner, allowing for timely action. As another embodiment, the alarm device issues an audible alarm. For example, when the processing device determines the portable air conditioner is tilted, the alarm device issues a first alarm, such as a regular beeping sound. Once the operator is aware of the tilt, they straighten the air conditioner, and the alarm ends. When the processing device determines the portable air conditioner is tipped, the alarm device issues a second alarm, such as a continuous beeping sound. Simultaneously, the processing device sends a command to the control device to "stop the compressor, fan, and other loads." The control device then stops the compressor and fan, or even shuts down the portable air conditioner entirely, preventing damage or fire caused by abnormal compressor or fan operation.

[0045] Specifically, the portable air conditioner is equipped with at least three sensors, arranged sequentially from high to low at points A, B, and C. The angle between the line BC connecting the positions of the two sensors at points B and C and the horizontal direction is α. The angle between the line AC connecting the positions of the two sensors at points A and C and the horizontal direction is β.

[0046] That is, when the sensor at point C receives tilt information, it sends the tilt information to the processing device. The processing device determines that the portable air conditioner is in normal condition and does not take any action. When the sensor at point B receives tilt information, it sends the tilt information to the processing device. The processing device determines that the portable air conditioner is tilted, and the alarm device emits a regular beeping sound. After hearing this, the operator can straighten the portable air conditioner. When the sensor at point A receives tilt information, it sends the tilt information to the processing device. The processing device determines that the portable air conditioner is tipped over, and the alarm device emits a continuous beeping sound. At the same time, the portable air conditioner stops under the control of the control device. The operator straightens the air conditioner, checks whether any functions of the air conditioner are abnormal, and takes appropriate measures.

[0047] Furthermore, the processing device determines the tilt direction of the portable air conditioner based on the angle information detected by the sensor.

[0048] In the above embodiment, the lines connecting points A, B, and C form a diagonal line, a curve, or two broken lines. Regardless of the form, the tilt state of the portable air conditioner is effectively detected, and an alarm is issued when necessary. However, this detection method can only detect the tilt state of the portable air conditioner in one direction; when the tilt state is in the opposite direction, it cannot accurately detect the tilt state of the air conditioner.

[0049] Furthermore, two sensors are installed at points D and E inside the portable air conditioner, and the heights of the three positions (C, D, and E) increase sequentially. The line connecting ABC and the line connecting CDE intersects at point C. The angle between the line DC connecting the positions of the two sensors at points D and C and the horizontal direction is α. The angle between the line EC connecting the positions of the two sensors at points E and C and the horizontal direction is β.

[0050] C is the lowest point among the five points. As a preferred method, a straight line perpendicular to the ground is drawn with C as the base point. Points A and B, and points D and E are located on both sides of the straight line. Then, the sensors at each point can not only detect the tilt state of the portable air conditioner, but also detect the tilt direction.

[0051] Specifically, such as Figure 2 As shown, the information detection device consists of a channel that is sequentially connected at points A, B, C, D, and E, with a sensor installed at each of these points. A rolling element is provided within the channel.

[0052] In one specific implementation, the information monitoring device is a channel. As described above, the channel forms a straight line with two channels on either side, each at angles α and β to the horizontal ground. A rolling element is installed within the channel. When the portable air conditioner is in normal operation, the rolling element is at point C. A sensor at point C detects the rolling element, and the processing device considers the portable air conditioner not tilted and takes no action. When the portable air conditioner tilts, and the rolling element reaches point B or D under gravity, the processing device determines that the tilt exceeds 30° and is in a tilted state. The alarm device emits a regular beeping sound, and the operator can then straighten the portable air conditioner. When the rolling element moves to point A or E, the processing device determines that the tilt exceeds 45° and is in a tipping state. The alarm device emits a continuous beeping sound, the control device stops the portable air conditioner, the operator straightens the air conditioner, and performs a functional test. If a malfunction is found, appropriate repair measures are taken, or the unit is scrapped.

[0053] In one implementation, the channel is a U-shaped pipe.

[0054] Furthermore, the information detection device is installed on the inner wall of the wall panel of the portable air conditioner.

[0055] A U-shaped pipe is installed on the inner wall of the wall panel of the portable air conditioner casing. A sensor is installed at point C at the lowest end of the U-shaped pipe. Two sensors are installed at two points on each side, according to angles α and β, namely, sensors at points A and B, and sensors at points D and E. A rolling element is placed inside the pipe.

[0056] Furthermore, the tilting direction includes a first X-axis direction and a second X-axis direction that are opposite to each other, as well as a first Y-axis direction and a second Y-axis direction that are opposite to each other.

[0057] As explained above, a detection device installed on one side panel of the portable air conditioner can only detect tilting in one axial direction, such as the X-axis. When the portable air conditioner tilts in the Y-axis direction, the detection device will not be able to accurately detect the tilt. For example, if the portable air conditioner tilts 15° in the X-axis direction and 40° in the Y-axis direction, the overall tilt should be considered tipping over. However, because the sensor cannot detect the tilt in the Y-axis direction, the processing device still considers the portable air conditioner to be in a normal state. Therefore, the sensor should detect the tilt in four directions as described above: the first and second X-axis directions, and the first and second Y-axis directions, which are opposite to each other.

[0058] Specifically, such as Figure 3 As shown, an information detection device is installed on the inner side wall of each of the two adjacent wall panels of the portable air conditioner.

[0059] As one implementation method, an information detection device can be installed on each of the two adjacent side walls of the portable air conditioner to achieve the above-mentioned accurate judgment of the tilt state.

[0060] Furthermore, the sensor is an infrared sensor.

[0061] When the rolling element rolls to the sensor position, it is detected by infrared light, and the processing device can then receive the corresponding tilt state. Specifically, to achieve tilt state detection, as an example, it can be achieved by... Figure 4 The circuit diagram shown is implemented.

[0062] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
