Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioning sterilization control method, device, and wall-mounted air conditioner. Background Technology

[0002] As people's living standards improve, air conditioners are becoming increasingly widely used. The indoor unit of an air conditioner exchanges heat with the air in the room. Indoor air enters the unit's casing through the air inlet, exchanges heat with the evaporator, and then exits into the room through the air outlet. However, after prolonged use, air conditioners accumulate a large number of bacteria inside. When indoor air flows through the inside of the indoor unit, it carries these bacteria into the room, leading to a decline in indoor air quality and, in severe cases, harming people's health.

[0003] Currently, most air conditioners on the market place sterilization devices at the air outlet to sterilize the air flowing out of the air conditioner. However, the continuous output of negative ions in a fixed position results in a limited ionization range, poor sterilization effect, and negatively impacts user experience. Summary of the Invention

[0024] If, according to the fan test results fed back by the sterilization device, the fan speed of all ion wind generating modules increases from the minimum value to the maximum value, then the sterilization mode is set to the start state.

[0025] If, according to the fan test results fed back by the sterilization device, the fan speed of at least one ion wind generating module has not increased from the minimum value to the maximum value, then the sterilization mode is set to the off state, and an alarm message is sent to the control terminal of the wall-mounted air conditioner.

[0030] According to an air conditioning sterilization control method provided by the present invention, after controlling the venting arm to perform the next movement at the relative speed and adjusting the sterilization device to the target operating state, the method further includes:

[0031] If the runtime of the sterilization mode is determined to be greater than or equal to a preset threshold, a shutdown command is sent to the sterilization device so that the sterilization device can stop operating according to the shutdown command;

[0032] If it is determined that the sterilization device has stopped operating, a state restoration command is sent to the wall-mounted air conditioner so that the wall-mounted air conditioner can restore to its initial state according to the state restoration command.

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0055] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

[0056] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” are intended to include the plural forms.

[0057] The terms “comprising” and “including” indicate the presence of the described feature, whole, step, operation, element and / or component, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or collections thereof.

[0058] Figure 1 This is one of the flowcharts illustrating the air conditioning sterilization control method provided by the present invention. For example... Figure 1 As shown, the air conditioner sterilization control method provided in this embodiment of the invention includes: step 101, determining the relative displacement of the air duct arm under the current movement when it is determined that the sterilization mode of the wall-mounted air conditioner is in the activated state.

[0059] The air intake arm extends and retracts vertically at the bottom of the wall-mounted air conditioner body. Relative displacement refers to the amount of displacement of the air intake arm relative to the bottom position of the wall-mounted air conditioner body during its up-and-down reciprocating motion.

[0060] It should be noted that the execution subject of the air conditioner sterilization control method provided in the embodiments of the present invention is an air conditioner sterilization control device. This device can be a processor integrated into the wall-mounted air conditioner body in the form of an electronic chip, a central processing unit (CPU), a micro control unit (MCU), a field-programmable gate array (FPGA), etc.

[0061] It should be noted that a through hole is opened in the vertical direction at the bottom of the casing of the wall-mounted air conditioner body, so that the air guide arm mechanically connected to it can reciprocate in the vertical direction. At the same time as the air guide arm moves in and out relative to the wall-mounted air conditioner body, the sterilization device arranged on the vertical surface of the air guide arm ionizes the indoor air and outputs the ionized airflow into the indoor space in the horizontal plane exposed outside the wall-mounted air conditioner body perpendicular to the air guide arm.

[0062] It should be noted that before step 101, the user needs to send an activation command through the transmission medium to activate the working mode of the wall-mounted air conditioner, so that the indoor unit in the air conditioning system operates at the default fan speed of the mode, while the outdoor unit operates at the default frequency of the mode and drives the air intake arm to extend and retract in the vertical direction.

[0063] The operating modes include, but are not limited to, heating mode, cooling mode, dehumidification mode, etc., and the embodiments of the present invention do not specifically limit them.

[0064] Optionally, the user can transmit activation commands via a control device and an air conditioning system through wireless communication. This allows the air conditioning system to initialize its operating mode while simultaneously driving the air vent arm to extend and retract relative to the air conditioning unit.

[0065] Optionally, the user can issue an activation command via voice interaction. The air conditioning system receives the activation command, performs voice recognition, initializes the corresponding working mode, and drives the air vent arm to extend and retract relative to the air conditioning body.

[0066] Specifically, in step 101, when the air conditioning sterilization control device determines that the sterilization mode has been activated based on the operating status of the wall-mounted air conditioner body and the sterilization device independently installed perpendicular to the wall-mounted air conditioner body, it monitors in real time the displacement of the guide arm relative to the wall-mounted air conditioner body during its movement. The hinge point near the wall-mounted air conditioner body is taken as the minimum limit position of the extension displacement, and the position of the bottom surface of the guide arm when it is fully extended out of the wall-mounted air conditioner body is taken as the maximum limit position of the extension displacement. The amount of displacement and the direction of movement of the bottom surface of the guide arm relative to the minimum limit position at any given moment are integrated into a relative displacement.

[0067] In this embodiment of the invention, the method of generating relative displacement is not specifically limited.

[0068] For example, Figure 2 This is a schematic diagram of the movement of the drainage arm in the sterilization mode provided by the present invention. (See diagram below.) Figure 2 As shown, a definition process for the relative displacement between extension positions A and B is given:

[0069] At the current moment, the bottom of the drainage arm is in the extended / retracted position A. Record the displacement 'a' of A relative to the minimum limit position O1. Based on historical displacement data, if the displacement 'a' shows a gradually increasing trend compared to historical displacements, it is determined that the drainage arm is currently in the process of descending from O1 to A. The direction of this displacement is then considered the descending direction, and the current relative displacement is recorded as +a. This continues until the maximum limit position O2 is reached, at which point the reverse ascending process is automatically executed. Conversely, if the displacement 'a' does not increase, it is determined that the drainage arm is currently in the process of ascending from O2 to A. The direction of this displacement is then considered the ascending direction, and the current relative displacement is recorded as -a. This continues until the minimum limit position O1 is reached, at which point the reverse descending process is automatically executed.

[0070] Similarly, if the bottom of the drainage arm is currently in the extended / retracted position B, record the displacement b of B relative to the minimum limit position O1. Combined with historical displacement data, if the displacement b shows a gradually increasing trend compared to historical displacements, it is determined that the drainage arm is currently in the process of descending from O1 to B, and its displacement direction is corresponding to the descending direction. The current relative displacement is recorded as +b, until it descends to the maximum limit position O2, at which point the reverse ascending process is automatically executed. Conversely, if the displacement b is not increasing, it is determined that the drainage arm is currently in the process of ascending from O2 to B, and its displacement direction is corresponding to the ascending direction. The current relative displacement is recorded as -b, until it ascends to the minimum limit position O1, at which point the reverse descending process is automatically executed.

[0071] Step 102: Based on the relative displacement, determine the relative velocity of the drainage arm in the next movement, as well as the target operating state of the sterilization device carried by the drainage arm.

[0072] The direction of the relative velocity is the same as the direction of movement of the drainage arm.

[0073] Specifically, in step 102, the air conditioning sterilization control device uses the relative displacement obtained in step 101 to calculate the relative speed corresponding to the continued motion trend of the drainage arm at the next moment, and the target operating state to be adjusted by the sterilization device on the drainage arm in the next moment in accordance with the motion trend of the drainage arm.

[0074] Step 103: While controlling the drainage arm to make the next movement at a relative speed, the sterilization device is also adjusted to the target operating state.

[0075] Specifically, in step 103, the air conditioning sterilization control device encapsulates the relative speed of the guide arm and the target operating status of the sterilization device on the guide arm, which were calculated in step 102, into a sterilization control command and sends it to the guide arm.

[0076] The drainage arm receives and responds to a sterilization control command, driving the movement components of the drainage arm to adjust accordingly, so that the drainage arm continues its original direction of motion at the relative speed contained in the sterilization control command for the next moment. At the same time, it also drives the sterilization device in the drainage arm to adjust the current operating state to the target operating state contained in the sterilization control command.

[0077] The direction of relative velocity is consistent with the direction of movement of the drainage arm. That is, except for the minimum and maximum limit positions, the direction of relative velocity at other movement positions is the same as the direction of relative displacement. At the minimum limit position, although the direction of relative displacement is upward (corresponding to the symbol "-"), the drainage arm can be automatically triggered to perform a downward movement in the opposite direction at this position, so the direction of relative velocity is downward (corresponding to the symbol "+").

[0078] Similarly, at the maximum limit position, although the direction of relative displacement is downward (i.e., the corresponding sign "+"), the direction of relative velocity is upward (i.e., the corresponding sign "-") because this position can automatically trigger the drainage arm to perform an upward movement in the opposite direction.

[0079] In this embodiment of the invention, when the sterilization mode is determined to be activated, the decision is made using the relative displacement of the guide arm during its extension and retraction. Based on this relative displacement, the relative velocity of the guide arm during its next movement is calculated, along with the target operating state adaptively adjusted by the sterilization device on the guide arm during the next movement. This ensures that the intensity of the ionized airflow output by the sterilization device adapts to the changing position of the guide arm. Driven by the extension and retraction of the guide arm, the ionized airflow output by the sterilization device forms a surrounding flow with the air conditioning air, achieving rapid and uniform mixing of the ionized airflow within the air conditioning air. This comprehensively covers the sterilization range of the indoor space, enhancing the sterilization effect and efficiency.

[0080] Based on any of the above embodiments, the relative speed of the drainage arm and the target operating state of the sterilization device carried by the drainage arm are determined based on the relative displacement, including: obtaining the fan speed setting of the wall-mounted air conditioner body.

[0081] Specifically, in step 102, the air conditioning sterilization control device determines the fan speed setting to be activated in the current working mode based on the operating status of the wall-mounted air conditioner.

[0082] The target's operating state is determined using the first mathematical model and relative displacement.

[0083] The first mathematical model includes a mapping relationship between the relative displacement of the drainage arm and the operating status of the sterilization device. The target operating status includes the operating power or fan speed of each ion wind generating module in the sterilization device.

[0084] It should be noted that the first mathematical model includes a one-to-one functional relationship between the relative displacement of the drainage arm and the operating state of the sterilization device.

[0085] The operating status of the sterilization device can be either the operating power of the sterilization device or the fan speed.

[0086] Preferably, the sterilization device may include multiple horizontally arranged ion wind generating modules, and its operating status is the operating power or fan speed of each ion wind generating module.

[0087] The embodiments of the present invention do not specifically limit the form of the first mathematical model.

[0088] Optionally, the first mathematical model can be a form with multiple rows and two columns, one column representing the relative displacement of the drainage arm and the other column representing the operating status of the sterilization device.

[0089] Alternatively, the first mathematical model can also be a computational model trained using artificial intelligence technology regarding the operating status of the sterilization device.

[0090] Specifically, the air conditioning sterilization control device substitutes the relative displacement into the first mathematical model, and determines the target operating state corresponding to the relative displacement based on the mapping relationship contained in the first mathematical model.

[0091] The relative speed is determined using the second mathematical model, wind speed setting, and relative displacement.

[0092] The second mathematical model includes the mapping relationship between the relative speed of the wall-mounted air conditioner body and the relative displacement of the air intake arm, and the relative speed of the air intake arm.

[0093] It should be noted that the second mathematical model includes a one-to-one mapping function relationship between the fan speed setting of the wall-mounted air conditioner body and the relative displacement of the air intake arm, and the relative velocity of the air intake arm.

[0094] The embodiments of the present invention do not specifically limit the form of the second mathematical model.

[0095] Optionally, the second mathematical model can be a table with multiple rows and three columns, where the first two columns are the fan speed setting of the wall-mounted air conditioner body and the relative displacement of the air intake arm, respectively, and the other column is the relative speed of the air intake arm.

[0096] Alternatively, the second mathematical model can also be a computational model trained with respect to the relative velocity of the drainage arm using artificial intelligence techniques.

[0097] Specifically, the air conditioning sterilization control device substitutes the fan speed setting and relative displacement into the second mathematical model, and determines the relative speed corresponding to the relative displacement of the air intake arm under the influence of a certain fan speed setting based on the mapping relationship contained in the second mathematical model.

[0098] This invention utilizes a first mathematical model to calculate the target operating state corresponding to the relative displacement generated by the guide arm during its current extension and retraction. Then, a second mathematical model is used to calculate the relative velocity corresponding to the combined effect of the air conditioner's fan speed setting and the relative displacement of the guide arm. This allows the sterilization device on the guide arm to adaptively adjust its target operating state during the next movement of the guide arm at its relative velocity, ensuring that the intensity of the ionized airflow output by the sterilization device always adapts to changes in the position of the guide arm. Driven by the extension and retraction of the guide arm, the ionized airflow output by the sterilization device forms a surrounding flow with the air conditioning air, achieving rapid and uniform mixing of the ionized airflow within the air conditioning air. This comprehensively covers the sterilization range of the indoor space, enhancing the sterilization effect and efficiency.

[0099] Based on any of the above embodiments, the first mathematical model includes:

[0100] P = (a + b * |X|) * P N

[0101] Where P is the target operating state, P N X represents the rated maximum value of the sterilization device under operating conditions, a represents the relative displacement, b represents the compensation coefficient, and b represents the displacement conversion coefficient.

[0102] Specifically, the air conditioning sterilization control device can fit the compensation coefficient 'a' and displacement conversion coefficient 'b' based on a large amount of prior data, and then substitute the relative displacement 'X' into the first mathematical model for calculation. The calculation formula is as follows:

[0103] P = (a + b * |X|) * P N

[0104] Where P is the target operating state, P N X represents the rated maximum value of the sterilization device under operating conditions, a represents the relative displacement, b represents the compensation coefficient, and b represents the displacement conversion coefficient.

[0105] In this embodiment of the invention, the value of the constant term in the first mathematical model is not specifically limited.

[0106] For example, the compensation factor 'a' and the displacement conversion factor 'b' can be determined by the relative displacement at the maximum limit position. For instance, the value of X can range from 0 to 100 mm. To convert this magnitude of relative displacement to the range of operating power or fan speed, 'a' can be set to 0.1 and 'b' to 0.09.

[0107] This invention utilizes a first mathematical model to calculate the target operating state corresponding to the relative displacement of the guide arm during its extension and retraction. As the displacement of the guide arm relative to the air conditioner body increases, the intensity of the ion airflow output by the sterilization device correspondingly increases. During the extension and retraction of the guide arm, the sterilization device outputs ion airflow of corresponding intensity at different positions. This allows the ion airflow to be delivered at the intersection with the air conditioning airflow, forming a surrounding flow. This enables rapid and uniform mixing of the ion airflow within the air conditioning airflow, comprehensively covering the sterilization range of the indoor space and enhancing the sterilization effect and efficiency.

[0108] Based on any of the above embodiments, the second mathematical model includes:

[0109] V j =c*X 2

[0110] V s = c*(d-|X|) 2

[0111] Among them, V j The direction of motion of the drainage arm is a relative velocity from top to bottom, V s The direction of movement of the flow guide arm is the relative velocity from bottom to top, X is the relative displacement, c is the matching coefficient corresponding to the wind speed setting, and d is the rated extension and retraction displacement of the flow guide arm.

[0112] Specifically, the air conditioning sterilization control device substitutes the relative displacement X and the matching coefficient c corresponding to the fan speed setting into the second mathematical model for calculation. The calculation formula is as follows:

[0113] V j =c*X 2

[0114] V s = c*(d-|X|) 2

[0115] Where X is determined to be a "+" symbol, then V is used. j =c*X 2 Calculate the relative velocity V corresponding to the wind speed setting and relative displacement during the downward movement of the guide arm. j .

[0116] When it is determined that the symbol recorded in X is "-", then use V s = c*(d-|X|) 2 Calculate the relative velocity V corresponding to the wind speed setting and relative displacement during the upward movement of the guide arm. s .

[0117] In this embodiment of the invention, the value of the constant term in the second mathematical model is not specifically limited.

[0118] For example, the matching coefficient c corresponding to the fan speed setting can be determined by the fixed setting of the cross-flow fan of the wall-mounted air conditioner body. The larger the corresponding fan speed setting, the smaller the value of the matching coefficient c.

[0119] For example, the cross-flow fan speed of a wall-mounted air conditioner can be divided into 5 levels: strong, high speed, medium speed, low speed and silent. The matching coefficient c corresponding to each level is 0.1, 0.2, 0.3, 0.4 and 0.5 respectively.

[0120] Additionally, d represents the rated telescopic displacement of the drainage arm. For example, if X can range from 0 to 100 mm, then d would be 100 mm.

[0121] This invention utilizes a second mathematical model to calculate the relative velocity corresponding to the combined effects of the relative displacement of the air intake arm during its extension and retraction process and the rotational speed of the cross-flow fan. As the displacement of the air intake arm relative to the air conditioner body increases and the cross-flow fan force strengthens, the speed of the air intake arm correspondingly increases. During the extension and retraction of the air intake arm, at its extreme position, the relative velocity of the air intake arm rapidly changes from maximum to zero, forming a surrounding flow at the point of intersection with the air conditioning air. This achieves rapid and uniform mixing of the ionized airflow within the air conditioning air, comprehensively covering the sterilization range of the indoor space and enhancing the sterilization effect and efficiency.

[0122] Based on any of the above embodiments, before determining the relative displacement of the drainage arm under the current movement, the method further includes: sending a fan test command to the sterilization device.

[0123] Specifically, before step 101, after determining that the sterilization mode is activated, the air conditioning sterilization control device encapsulates the control command for increasing the fan speed of the sterilization device from 0 to the rated maximum speed into a fan test command and sends it to the sterilization device to test whether the sterilization device can start normally.

[0124] If the fan speed of all ion wind generating modules increases from the minimum to the maximum value according to the fan test results fed back by the sterilization device, then the sterilization mode is set to the start state.

[0125] If, according to the fan test results fed back by the sterilization device, the fan speed of at least one ion wind generating module has not increased from the minimum value to the maximum value, then the sterilization mode will be set to the off state, and an alarm message will be sent to the control terminal of the wall-mounted air conditioner.

[0126] The fan test results are obtained by the sterilization device in response to the fan test command.

[0127] It should be noted that the sterilization device receives and responds to the fan test command, organizes the operating status of each fan in the sterilization device into the fan test results, and uploads the fan test results to the air conditioning sterilization control device.

[0128] Specifically, the air conditioning sterilization control device determines whether the sterilization device can successfully activate the sterilization mode based on the fan test results fed back by the sterilization device, wherein:

[0129] If the air conditioning sterilization control device analyzes the fan test results and finds that each fan of the sterilization device can be successfully started and the fan speed can be successfully increased from 0 to the maximum value, then the sterilization device can be determined to have successfully activated the sterilization mode.

[0130] If the air conditioner sterilization control device determines, based on the fan test results, that at least one fan of the sterilization device has failed to start successfully, or that the fan speed of at least one fan has failed to rise from 0 to the maximum value, then the sterilization device is deemed unable to successfully activate the sterilization mode and an alarm message is sent to the control terminal of the wall-mounted air conditioner.

[0131] The alarm information includes, but is not limited to, text information, audio-visual information, etc. The alarm information can guide users of remote terminals to pay attention to the malfunction of the sterilization device, and can also guide users to locate the cause of the malfunction and the faulty component of the sterilization device.

[0132] In this embodiment of the invention, after determining that the sterilization mode needs to be activated, a decision is made to send a fan test command to the sterilization device. Based on the fan test results returned by the sterilization device in response to the fan test command, it is determined whether the performance of the sterilization device can support the activation of the sterilization mode. This ensures that the sterilization device can achieve the expected working performance and avoids poor sterilization completion due to its own malfunction.

[0133] Based on any of the above embodiments, before sending the fan test command to the sterilization device, the method further includes: activating the air supply mode if it is determined that the initial state of the wall-mounted air conditioner is not the operating state.

[0134] Specifically, the air conditioning sterilization control device determines the initial state as when the wall-mounted air conditioner is in a closed state, i.e., not operating in any working mode, based on the operating status of the processor in the wall-mounted air conditioner body, and then controls the wall-mounted air conditioner to activate the air supply mode.

[0135] There are no specific restrictions on the fan speed of the wall-mounted air conditioner involved in the activated air supply mode.

[0136] Preferably, when the air conditioner sterilization control device determines that the wall-mounted air conditioner is off, it controls the wall-mounted air conditioner to start the air supply mode corresponding to the high fan speed setting to accelerate airflow.

[0137] Once the air supply mode is confirmed to be on, activate the sterilization mode.

[0138] Specifically, after the air conditioner sterilization control device determines that the wall-mounted air conditioner has successfully switched from the initial off state to the air supply mode based on the operating status of the fan in the wall-mounted air conditioner body, it controls the sterilization device set perpendicular to the wall-mounted air conditioner body to start, so as to activate the sterilization mode.

[0139] In this embodiment of the invention, when it is determined that the wall-mounted air conditioner is not operating in any working mode, the decision is made to first activate the air supply mode and then activate the sterilization mode. Furthermore, by controlling the intensity of the ion airflow output by the sterilization device to adapt to the position of the guide arm, the ion airflow and the air conditioning air form a surrounding flow, so that the ion airflow is quickly and evenly mixed in the air conditioning air, which can fully cover the sterilization range of the indoor space and enhance the sterilization effect and efficiency.

[0140] Based on any of the above embodiments, after controlling the drainage arm to make the next movement at a relative speed and adjusting the sterilization device to the target operating state, the method further includes: when it is determined that the operating time of the sterilization mode is greater than or equal to a preset threshold, sending a shutdown command to the sterilization device so that the sterilization device can stop operating according to the shutdown command.

[0141] Specifically, after step 103, the air conditioning sterilization control device statistically analyzes the working cycle of the sterilization device and compares the statistically analyzed runtime of the sterilization mode with a preset threshold for the runtime of the sterilization mode:

[0142] If the duration of the sterilization mode is greater than or equal to the preset threshold, it is determined that the sterilization mode has achieved the preset sterilization effect within the current duration of operation. In this case, a shutdown command can be sent to the sterilization device to instruct it to stop the operation of each component and end the sterilization mode.

[0143] If the duration of the sterilization mode is less than the preset threshold, it is determined that the sterilization mode has not yet achieved the preset sterilization effect within the current duration of operation, and the sterilization device continues to operate continuously.

[0144] In this embodiment of the invention, the value of the preset threshold is not specifically limited.

[0145] For example, the preset threshold can be flexibly set according to the size of the indoor space.

[0146] For example, the preset threshold can also be set to a general fixed value based on empirical data, such as 10 minutes.

[0147] If the sterilization device stops operating, a status restoration command is sent to the wall-mounted air conditioner so that the wall-mounted air conditioner can restore itself to its initial state according to the status restoration command.

[0148] Specifically, when the air conditioning sterilization control device determines that the sterilization device has stopped operating based on its operating status, it encapsulates the control command for driving the wall-mounted air conditioner body to restore its initial state into a state restoration command and sends it to the wall-mounted air conditioner.

[0149] Figure 3 This is the second flowchart illustrating the air conditioning sterilization control method provided by this invention. For example... Figure 3 As shown, taking the arrangement of 10 ion generators and fans on the drainage arm, referred to as N1-N10, as an example, this embodiment of the invention provides a specific implementation process for air conditioning sterilization control:

[0150] (1) The air conditioning sterilization control device determines whether the initial state of the wall-mounted air conditioner is in operation based on the operating status of the wall-mounted air conditioner.

[0151] (2) If it is determined that the initial state of the wall-mounted air conditioner is not the working state, activate the high fan speed mode.

[0152] If the initial state of the wall-mounted air conditioner is determined to be the working state, maintain the original working mode.

[0153] (3) Send a fan test command to the sterilization device and use the ability of all fans to rise from 0 to the maximum value as the basis for judgment to determine whether the sterilization device is faulty.

[0154] (4) If it is determined that the sterilization device is faulty, an alarm message is sent to the control terminal of the wall-mounted air conditioner.

[0155] If it is determined that the sterilization device is not faulty, then the sterilization mode is activated.

[0156] (5) After activating the sterilization mode, keep all ion generators on. If the symbol recorded in X is "+", then use V. j =c*X 2 Calculate the relative velocity V corresponding to the wind speed setting and relative displacement during the downward movement of the guide arm. j And using P = (a + b * |X|) * P N The target operating state is calculated.

[0157] If the symbol recorded in X is determined to be "-", then use V s = c*(d-|X|) 2 Calculate the relative velocity V corresponding to the wind speed setting and relative displacement during the upward movement of the guide arm. sAnd using P = (a + b * |X|) * P N The target operating state is calculated.

[0158] (6) Continue working for 10 minutes.

[0159] (7) Send a shutdown command to the sterilization device, and all fans and ion generators in groups N1-N10 will stop operating.

[0160] (8) If the initial state of the wall-mounted air conditioner is not the working state, turn off the high fan speed mode to restore the wall-mounted air conditioner to the initial off state.

[0161] If the initial state of the wall-mounted air conditioner is the working state, the wall-mounted air conditioner will maintain its original working mode.

[0162] This invention verifies the sterilization effect by measuring the runtime of the sterilization mode. After the preset runtime is reached, a decision is made to stop the sterilization device's operation via a shutdown command, and a state restoration command is used to restore the wall-mounted air conditioner to its initial state. This enables automated control throughout the entire lifecycle of the sterilization operation, stopping operation after confirming the achievement of the expected sterilization effect, thus saving energy.

[0163] Figure 4 This is a schematic diagram of the air conditioning sterilization control device provided by the present invention. Based on any of the above embodiments, such as... Figure 4 As shown, the air conditioning sterilization control device provided in this embodiment of the invention includes a displacement determination module 410, a displacement adaptation module 420, and a sterilization control module 430, wherein:

[0164] The displacement determination module 410 is used to determine the relative displacement of the drainage arm under the current movement when it is determined that the sterilization mode of the wall-mounted air conditioner is in the activated state.

[0165] The displacement adaptation module 420 is used to determine the relative velocity of the drainage arm in the next movement and the target operating state of the sterilization device carried by the drainage arm based on the relative displacement.

[0166] The sterilization control module 430 is used to control the drainage arm to make the next movement at a relative speed, while also adjusting the sterilization device to the target operating state.

[0167] The air vent arm extends and retracts vertically at the bottom of the wall-mounted air conditioner body. The relative displacement is the amount of displacement of the air vent arm relative to the bottom position of the wall-mounted air conditioner body during its reciprocating up-and-down motion. The direction of the relative velocity is the same as the direction of movement of the air vent arm.

[0168] Specifically, the displacement determination module 410, the displacement adaptation module 420, and the sterilization control module 430 are electrically connected in sequence.

[0169] The displacement determination module 410 determines that the sterilization mode has been activated based on the operating status of the wall-mounted air conditioner body and the sterilization device independently set perpendicular to the wall-mounted air conditioner body. It monitors the displacement of the guide arm relative to the wall-mounted air conditioner body in real time during its movement. The hinge point near the wall-mounted air conditioner body is taken as the minimum limit position of the extension displacement, and the position of the bottom surface of the guide arm when it is fully extended out of the wall-mounted air conditioner body is taken as the maximum limit position of the extension displacement. The displacement amount and direction of the guide arm bottom surface relative to the minimum limit position at any current moment are integrated into the relative displacement.

[0170] The displacement adaptation module 420 uses the relative displacement obtained in the displacement determination module 410 to calculate the relative velocity corresponding to the drainage arm continuing its movement trend at the next moment, and the target operating state that the sterilization device on the drainage arm needs to adjust to in accordance with the movement trend of the drainage arm at the next moment.

[0171] The sterilization control module 430 encapsulates the relative speed of the drainage arm and the target operating status of the sterilization device on the drainage arm, calculated by the displacement adaptation module 420, into a sterilization control command and sends it to the drainage arm.

[0172] The drainage arm receives and responds to a sterilization control command, driving the movement components of the drainage arm to adjust accordingly, so that the drainage arm continues its original direction of motion at the relative speed contained in the sterilization control command for the next moment. At the same time, it also drives the sterilization device in the drainage arm to adjust the current operating state to the target operating state contained in the sterilization control command.

[0173] Optionally, the displacement adaptation module 420 includes a wind speed level acquisition unit, an operating status determination unit, and a relative speed determination unit, wherein:

[0174] The fan speed setting acquisition unit is used to acquire the fan speed setting of the wall-mounted air conditioner.

[0175] The operating state determination unit is used to determine the target operating state using the first mathematical model and relative displacement.

[0176] The relative velocity determination unit is used to determine the relative velocity using the second mathematical model, wind speed setting, and relative displacement.

[0177] The first mathematical model includes the mapping relationship between the relative displacement of the air intake arm and the operating state of the sterilization device. The second mathematical model includes the mapping relationship between the relative speed of the wall-mounted air conditioner and the relative displacement of the air intake arm, and the relative velocity of the air intake arm. The target operating state includes the operating power or fan speed of each ion wind generating module in the sterilization device.

[0178] Optionally, the first mathematical model includes:

[0179] P = (a + b * |X|) * P N

[0180] Where P is the target operating state, P N X represents the rated maximum value of the sterilization device under operating conditions, a represents the relative displacement, b represents the compensation coefficient, and b represents the displacement conversion coefficient.

[0181] Optionally, the second mathematical model includes:

[0182] V j =c*X 2

[0183] V s = c*(d-|X|) 2

[0184] Among them, V j The direction of motion of the drainage arm is a relative velocity from top to bottom, V s The direction of movement of the flow guide arm is the relative velocity from bottom to top, X is the relative displacement, c is the matching coefficient corresponding to the wind speed setting, and d is the rated extension and retraction displacement of the flow guide arm.

[0185] Optionally, the device further includes a test module and a test response module, wherein:

[0186] The testing module is used to send fan test commands to the sterilization device.

[0187] The test response module is used to determine that the sterilization mode is successfully activated if the fan speed of all ion wind generating modules increases from the minimum value to the maximum value according to the fan test results fed back by the sterilization device.

[0188] The test response module is also used to determine that the sterilization mode activation has failed if the fan speed of at least one ion wind generating module has not increased from the minimum value to the maximum value according to the fan test results fed back by the sterilization device, and to send an alarm message to the control terminal of the wall-mounted air conditioner.

[0189] The fan test results are obtained by the sterilization device in response to the fan test command.

[0190] Optionally, the device further includes an air supply activation module and a sterilization activation module, wherein:

[0191] The air supply activation module is used to activate the air supply mode when it is determined that the initial state of the wall-mounted air conditioner is not in an operating state.

[0192] The sterilization activation module is used to activate the sterilization mode when the air supply mode is confirmed to be on.

[0193] Optionally, the device further includes a sterilization shutdown module and a state recovery module, wherein:

[0194] The sterilization shutdown module is used to send a shutdown command to the sterilization device when the runtime of the sterilization mode is greater than or equal to a preset threshold, so that the sterilization device can stop operating according to the shutdown command.

[0195] The state recovery module is used to send a state recovery command to the wall-mounted air conditioner when it is determined that the sterilization device has stopped operating, so that the wall-mounted air conditioner can restore to its initial state according to the state recovery command.

[0196] The air conditioning sterilization control device provided in this embodiment of the invention is used to execute the air conditioning sterilization control method described above. Its implementation method is the same as that of the air conditioning sterilization control method provided by this invention, and it can achieve the same beneficial effects. It will not be described again here.

[0197] In this embodiment of the invention, when the sterilization mode is determined to be activated, the relative displacement of the drainage arm during its extension and retraction is used to calculate the relative velocity of the drainage arm during its next movement. The target operating state of the sterilization device on the drainage arm is also adaptively adjusted during the next movement of the drainage arm, ensuring that the intensity of the ionized airflow output by the sterilization device always adapts to the position of the drainage arm. Driven by the extension and retraction of the drainage arm, the ionized airflow output by the sterilization device forms a surrounding flow with the air conditioning air, achieving rapid and uniform mixing of the ionized airflow within the air conditioning air. This comprehensively covers the sterilization range of the indoor space, enhancing the sterilization effect and efficiency.

[0198] Figure 5 This is one of the structural schematic diagrams of the wall-mounted air conditioner provided by the present invention. Based on any of the above embodiments, such as... Figure 5 As shown, the wall-mounted air conditioner provided in this embodiment of the invention includes: a wall-mounted air conditioner body 510, and the wall-mounted air conditioner body 510 includes a processor 511. The processor 511 is used to implement any of the above-mentioned air conditioner sterilization control methods.

[0199] A vertically oriented cavity is formed at the bottom of the wall-mounted air conditioner body 510 to allow the air-draining arm 520 to reciprocate within the cavity. The air-draining arm 520 supports the sterilization device 521. Under the control of the processor 511, the sterilization device 521 controls the air-draining arm 520 to move at a relative speed, while simultaneously adjusting the sterilization device 521 to the target operating state.

[0200] The length of the accommodating cavity is greater than or equal to the length of the drain arm 520. The relative displacement is the amount of displacement of the drain arm 520 relative to the bottom position of the wall-mounted air conditioner body 510 during its reciprocating up-and-down motion. The direction of the relative velocity is the same as the direction of motion of the drain arm 520.

[0201] Specifically, the wall-mounted air conditioner includes a wall-mounted air conditioner body 510, and a accommodating cavity vertically formed at the bottom of the casing of the wall-mounted air conditioner body 510 for the vertical extension and retraction of the air intake arm 520. A sterilization device 521 is provided on the vertical surface of the air intake arm 520. When the processor 511 determines that the sterilization mode has been activated based on the operating status of the sterilization device 521, it controls the sterilization device 521 to ionize the indoor air, and drives the motion components of the air intake arm 520 to adjust accordingly based on the relative displacement of the air intake arm 520 in the vertical direction, so that the air intake arm 520 continues its original direction of motion at the relative speed included in the sterilization control command for the next moment of movement. At the same time, it also drives the sterilization device 521 in the air intake arm 520 to adjust the current operating state to the target operating state included in the sterilization control command.

[0202] In this embodiment of the invention, a sterilization device is installed on a retractable air intake arm perpendicular to the bottom of the wall-mounted air conditioner body. The relative displacement of the air intake arm during its extension and retraction allows for independent control of both the air intake arm and the sterilization device. Driven by the extension and retraction of the air intake arm, the ionized airflow output by the sterilization device forms a surrounding flow with the air conditioning air, achieving rapid and uniform mixing of the ionized airflow within the air conditioning air. This comprehensively covers the sterilization area of ​​the indoor space, enhancing the sterilization effect and efficiency.

[0203] Figure 6 This is a second structural schematic diagram of the wall-mounted air conditioner provided by the present invention. Based on any of the above embodiments, such as... Figure 6 As shown, the sterilization device includes at least two ion wind generating modules 621 that are on the same horizontal line.

[0204] The ion wind generating module 621 includes an ion generator 621-1 and a fan 621-2.

[0205] Specifically, each ion wind generating module 621 arranged horizontally in the drainage arm 620 consists of a fan 621-2 embedded in a through hole, and an ion generator 621-1 disposed on the inner wall of the through hole above the fan 621-2.

[0206] Among them, the ion generator 621-1, in addition to producing a large number of active negative oxygen ions, also produces a large number of highly active neutral substances, short-lived active particles (such as O, OH, HO2, etc.) and long-lived active ions (such as excited-state N2, H2O2, etc.). The neutral substances add to the air washing, which has a greater effect and no by-products.

[0207] The 621-2 fan can achieve stepless speed regulation based on a DC motor, enabling quantitative direct control of changes in fan speed or operating power, thereby improving the 621-2 fan's response speed to changes.

[0208] In this embodiment of the invention, each ion generator module in the sterilization device is constructed by combining ion generators on the fans. This keeps the ion generators on when the sterilization mode is activated. By adjusting the output intensity of the ion airflow with corresponding control commands for different fan groups during the same working cycle, the intensity of the ion airflow output by the sterilization device can be adaptively changed according to the position of the guide arm through the combined control of the ion generator and the fans. The ion airflow output by the sterilization device forms a surrounding flow with the air conditioning air, achieving rapid and uniform mixing of the ion airflow in the air conditioning air. This can comprehensively cover the sterilization range of the indoor space, enhance the sterilization effect and efficiency, and reduce the construction cost to a certain extent.
