[0056] An air inlet component of the air conditioner, an air conditioner and a control method provided by the present invention have the following beneficial effects:

[0057] 1. The present invention simultaneously arranges a filtering component and a baffle component at the air inlet of the air conditioner, and through a set of driving components, which are respectively connected to the filtering component and the baffle component, to drive the movement of the filtering component and the baffle component respectively, so as to drive the filtering component to unfold for filtering when the filtering requirement is met, and drive the baffle component to open the air inlet of the air conditioner during the operation of the air conditioner, and drive the baffle component to close the air inlet of the air conditioner when it is closed, that is, the movement of the baffle component and the retraction and extension of the filter screen share a set of driving motors. Only through a set of driving motors can the driving movement of the baffle component and the retraction and extension effect of the filtering component be effectively completed. Fewer driving and transmission components are adopted, the operation is convenient, and the cost is low, solving the problems in the prior art that the number of driving and transmission components for protecting and removing dust at the air inlet of the air conditioner is large, the structure is complex, and the cost is relatively high.

[0058] 2. The present invention further adopts the structure of a sliding gear cooperating with the first, second, and third rotating shafts, and gears one and two. Through the movement of the sliding gear, it can move to the first state position: meshing with gear one, driving gear one and then driving the movement of the second rotating shaft to drive the filter screen to move to unfold or retract, and move to the second state position: meshing with gear two, driving gear two and then driving the movement of the third rotating shaft to drive the baffle component to move to open or close the air inlet of the air conditioner, so that the sliding gear can move and switch between the first state position and the second state position, thereby being able to drive the filter screen to move and drive the baffle component to move as needed to meet the comfort purpose of the user to turn on or off the air conditioner and filter the incoming air or not, and through the sliding gear, the effect of sharing the same set of driving motors for the rigid baffle and the retraction and extension of the filter screen is achieved. Fewer driving and transmission components are adopted, the operation is convenient, and the cost is low.

[0059] 3. The present invention also arranges an electromagnetic suction component, which can achieve the purpose and effect of driving the sliding gear to move between gear one and gear two, and realizing the switching between the states of meshing with gear one and meshing with gear two, and can drive the filter screen to move and drive the baffle component to move as needed to meet the comfort purpose of the user to turn on or off the air conditioner and filter the incoming air or not; further preferably, through the magnetic suction blocks arranged on both sides of the sliding gear and the electromagnet structures on the first rotating shaft on both sides of the sliding gear, by controlling which side of the electromagnet is energized, and then forming the magnetic force between the electromagnet and the magnetic suction block, the purpose of driving the sliding gear to move to which side is achieved, and it can drive the filter screen to move and drive the baffle component to move as needed to meet the comfort purpose of the user to turn on or off the air conditioner and filter the incoming air or not, and the effect of sharing the same set of driving motors for the rigid baffle and the retraction and extension of the filter screen is achieved, and fewer driving and transmission components are adopted.

[0060] 4. The present invention also arranges a first baffle component and a second baffle component on both sides of the air inlet of the air conditioner respectively, enabling the air inlet of the air conditioner to be opened when they move in opposite directions, and the air inlet to be closed when they move in opposite directions; preferably, the present invention adopts the structure of the first to fourth stay ropes, combined with the motors and the third rotating shafts on both sides. Due to the different winding directions and fixed positions of different stay rope structures, when the third rotating shafts on both sides move in different directions, the first and second baffle components on both sides can be pulled apart in opposite directions (to achieve lamination), so as to achieve the purpose of opening the air inlet, and the first and second baffle components can be pulled to meet in opposite directions to achieve the purpose of closing the air inlet. The transmission structure is simple, with a small number, easy to operate, and low in cost.

[0061] 5. The present invention also arranges the filter screen as a structure composed of multiple filter units with different filter hole sizes, controls the rotation of the filter screen on the reel, and can realize the change of the filter hole size facing the air inlet of the air conditioner. In combination with the structure for detecting the air volume on both sides of the filter screen, it can judge whether the filter screen is dirty or blocked according to the detection data. If it is judged that there is no dirt blockage, the optimal gap of the filter screen can be solved according to the operating state of the air conditioner to reduce the air inlet resistance when meeting the filtering requirements, improve the refrigeration and heating performance, and reduce power consumption; if it is judged that there is dirt blockage, the filter screen needs to be controlled to be cleaned and sterilized, realizing an air conditioner structure integrating baffle, filtration, cleaning, and sterilization.

[0076] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0077] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0078] Unless otherwise specifically stated, the relative arrangements of the components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0079] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0080] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures for the device.

[0092] The present invention also, through the provision of the electromagnetic suction assembly, can drive the sliding gear to move between the first gear and the second gear, achieving the purpose and effect of switching between the states of meshing with the first gear and meshing with the second gear respectively, and can drive the filter net to move and drive the baffle assembly to move as needed, so as to meet the comfort purposes of the user to turn on or off the air conditioner and filter the incoming air or not.

[0093] In some embodiments,

[0094] The electromagnetic suction assembly 25 includes a first electromagnet 251a and a second electromagnet 251b, as well as a first magnetic attraction block 252a and a second magnetic attraction block 252b.

The second electromagnet 251b is disposed on the first rotating shaft 22 and is located on the side of the sliding gear 28 away from the motor 21. The first magnetic attraction block 252a is disposed on the sliding gear 28 and faces the side of the motor 21. The second magnetic attraction block 252b is disposed on the sliding gear 28 and is located on the side away from the motor 21. The first gear 291 is closer to the motor 21 relative to the second gear 292. The first electromagnet 251a can be controlled to be energized to magnetically attract the first magnetic attraction block 252a, so that the sliding gear 28 moves to mesh with the first gear 291. The second electromagnet 251b can be controlled to be energized to magnetically attract the second magnetic attraction block 252b, so that the sliding gear 28 moves to mesh with the second gear 292.

[0095] The present invention further preferably adopts the structure of magnetic attraction blocks arranged on both sides of the sliding gear and electromagnets located on both sides of the first rotating shaft. By controlling which side of the electromagnet is energized, the magnetic force between the electromagnet and the magnetic attraction block is formed, achieving the purpose of driving the sliding gear to move to which side, and can drive the filter net to move and drive the baffle assembly to move as needed, so as to meet the comfort purposes of the user to turn on or off the air conditioner and filter the incoming air or not, achieving the effect of sharing the same set of driving motors for the retraction and extension of the rigid baffle and the filter net, and adopting fewer driving and transmission components.

[0096] The driving assembly of the present invention is installed on the panel body. The motor is connected to the first rotating shaft through a coupling. The first rotating shaft is preferably equipped with a spline, which drives the sliding gear to rotate through the spline. Electromagnets are installed at both ends of the spline. There are magnetic attraction blocks on the sliding gear. By energizing the electromagnets at different ends, the transmission is switched. When the electromagnet close to the motor is energized, the sliding gear meshes with the cylindrical first gear, and drives the second rotating shaft to rotate through a flat key to realize the retraction and extension of the filter net. When the electromagnet on the other side is energized, it meshes with the cylindrical second gear to realize the retraction and extension of the baffle.

A fourth sliding groove is provided on the right baffle three 173. The right baffle two 172 can slide onto the fourth sliding groove and form a stack with the right baffle three 173.

[0111] The present invention also adopts a structural form in which sliding grooves are arranged on the baffle plates, enabling adjacent baffle plates to slide on the sliding grooves to form an overlay, so as to achieve the purpose of opening the air outlet of the air conditioner and reduce the resistance.

[0112] The rigid baffle plate assembly of the present invention preferably has left and right side plates and is installed on the panel body. The baffle plates will move to both sides under the pulling of the ropes. Each of them is stacked and spliced by three rigid baffle plates, which can effectively reduce the occupied area. On one side below each baffle plate, there are preferably two pulleys, which can move in a directional manner along the sliding grooves for the retraction and extension of the baffle plates. There are limit plates around to prevent the pulleys from slipping out of the grooves. There are positioning holes on both sides of the front end of each baffle plate to limit the movement of the steel wire ropes.

[0113] In some embodiments,

[0114] The baffle plate assembly 1 further includes a first rope 161, a second rope 162, a third rope 163 and a fourth rope 164. When the driving assembly 2 includes a motor 21, a first rotating shaft 22 and a third rotating shaft 24:

[0115] On one side of the first baffle plate assembly, there are provided the motor 21, the first rotating shaft 22 and the third rotating shaft 24. On the third rotating shaft 24 on this side, there are provided a first wire groove 301 and a second wire groove 302. One end of the first rope 161 is wound around the first wire groove 301 in a first winding direction, and the other end of the first rope 161 is fixed to the second baffle plate assembly to be able to form a pulling force on the second baffle plate assembly in the direction towards the first baffle plate assembly; one end of the second rope 162 is wound around the second wire groove 302 in a second winding direction, and the other end of the second rope 162 is fixed to the first baffle plate assembly to be able to form a pulling force on the first baffle plate assembly in the direction away from the second baffle plate assembly; the first winding direction is opposite to the second winding direction;

[0116] On one side of the second baffle plate assembly, there are provided the motor 21, the first rotating shaft 22 and the third rotating shaft 24. On the third rotating shaft 24 on this side, there are provided a third wire groove 303 and a fourth wire groove 304. One end of the third rope 163 is wound around the third wire groove 303 in a third winding direction, and the other end of the third rope 163 is fixed to the first baffle plate assembly to be able to form a pulling force on the first baffle plate assembly in the direction towards the second baffle plate assembly; one end of the fourth rope 164 is wound around the fourth wire groove 304 in a fourth winding direction, and the other end of the fourth rope 164 is fixed to the second baffle plate assembly to be able to form a pulling force on the second baffle plate assembly in the direction away from the first baffle plate assembly; the third winding direction is opposite to the fourth winding direction.

[0117] The present invention preferably adopts the structure of the first to fourth stay ropes, combined with the motors and the third rotating shafts on both sides. Due to the different winding directions and fixed positions of different stay rope structures, when the third rotating shafts on both sides move in different directions, the first and second baffle components on both sides can be pulled apart in opposite directions (realizing lamination) to achieve the purpose of opening the air inlet, and the first and second baffle components can be pulled to meet in opposite directions to achieve the purpose of closing the air inlet. The transmission structure is simple, with a small number of components, easy to operate, and low in cost.

[0118] In some embodiments,

[0119] When the air inlet of the air conditioner needs to be closed, the motor 21 on one side of the first baffle component is controlled to rotate, and the third rotating shaft 24 on this side is driven to rotate in the first direction, so that the first rope 161 is tightened and pulls the second baffle component towards the first baffle component. At this time, the second rope 162 becomes loose. At the same time, the motor 21 on one side of the second baffle component is controlled to rotate, and the third rotating shaft 24 on this side is driven to rotate in the third direction, so that the third rope 163 is tightened and pulls the first baffle component towards the second baffle component. At this time, the fourth rope 164 becomes loose;

[0120] When the air inlet of the air conditioner needs to be opened, the motor 21 on one side of the first baffle component is controlled to rotate, and the third rotating shaft 24 on this side is driven to rotate in the second direction, so that the second rope 162 is tightened and pulls the first baffle component away from the second baffle component. At this time, the first rope 161 becomes loose. At the same time, the motor 21 on one side of the second baffle component is controlled to rotate, and the third rotating shaft 24 on this side is driven to rotate in the fourth direction, so that the fourth rope 164 is tightened and pulls the second baffle component away from the first baffle component. At this time, the third rope 163 becomes loose;

[0121] The first direction and the second direction are opposite rotation directions, and the third direction and the fourth direction are opposite rotation directions.

[0122] This is the specific control and movement mode of the four stay ropes of the present invention when the air inlet of the air conditioner needs to be opened or closed. Due to the different winding directions and fixed positions of different stay rope structures, when the third rotating shafts on both sides move in different directions, the first and second baffle components on both sides can be pulled apart in opposite directions (realizing lamination) to achieve the purpose of opening the air inlet, and the first and second baffle components can be pulled to meet in opposite directions to achieve the purpose of closing the air inlet. The transmission structure is simple, with a small number of components, easy to operate, and low in cost.

[0123] The rigid baffle component is retracted and released by eight steel wires, and the winding method is as Figure 6As shown, since the left and right baffles are both symmetric, in order to ensure uniform force when pulling the baffles, steel wires are arranged on both sides. Only one side is shown in the figure, and the other side is symmetric to it. Fix the two steel wires on the positioning holes on the two side surfaces of the right baffle, and pass them through the positioning holes of the first, second, and third left baffles in sequence. When viewed from the front of the air conditioner, wind the two steel wires clockwise around the third rotating shaft for several turns and then fix them on the first wire groove to leave enough margin. Fix the two steel wires on the positioning holes on the two sides of the first left baffle, pass them through the positioning holes of the second and third left baffles in sequence, wind them counterclockwise around the third rotating shaft for several turns and fix them on the second wire groove of the third rotating shaft. The same applies to the right baffle. Fix the two steel wires on the positioning holes on the two sides of the first left baffle, pass them through the positioning holes of the first, second, and third right baffles in sequence, wind the two steel wires counterclockwise around the third rotating shaft for several turns and then fix them on the first wire groove to leave enough margin. Fix the two steel wires on the positioning holes on the two sides of the first right baffle, pass them through the positioning holes of the second and third right baffles in sequence, wind them clockwise around the third rotating shaft for several turns and fix them on its second wire groove. When retracting the baffle, the third left rotating shaft rotates counterclockwise, the driving rope contracts to drive the left baffle to move leftward in sequence, the driving rope relaxes, the third right rotating shaft rotates clockwise, the fourth rope contracts to drive the right baffle to move rightward in sequence, the third driving rope relaxes, and the two motors move synchronously, thereby ensuring that the retracting and releasing lengths of the driving ropes are equal and keeping the driving ropes in a tensioned state. When releasing the baffle, the left shaft rotates clockwise, the first rope contracts to drive the right baffle to move leftward in sequence, the second rope relaxes, the right shaft rotates counterclockwise, the third rope contracts to drive the left baffle to move rightward in sequence, the fourth rope relaxes, and thus the folding and retracting of the baffle can be realized, reducing the number of driving and transmission parts.

[0124] In some embodiments,

[0125] When the first baffle assembly includes the first left baffle 111, the second left baffle 112, and the third left baffle 113, and the second baffle assembly includes the first right baffle 171, the second right baffle 172, and the third right baffle 173:

[0126] On the side edges of the first left baffle 111, the second left baffle 112, and the third left baffle 113, there are convex platforms protruding outward, and each convex platform has a positioning hole 14. On the side edges of the first right baffle 171, the second right baffle 172, and the third right baffle 173, there are also convex platforms protruding outward, and each convex platform has a positioning hole 14.

[0127] The first rope 161 passes through the positioning holes 14 on the third left baffle 113, the second left baffle 112, and the first left baffle 111 in sequence and is fixed to the positioning hole 14 on the first right baffle 171; the second rope 162 passes through the positioning holes 14 on the third left baffle 113 and the second left baffle 112 in sequence and is fixed to the positioning hole 14 on the first left baffle 111.

[0128] The third rope 163 sequentially passes through the positioning holes 14 on the right third baffle 173, the right second baffle 172, and the right first baffle 171, and is fixed to the positioning hole 14 on the left first baffle 111; the fourth rope 164 sequentially passes through the positioning holes on the right third baffle 173 and the right second baffle 172 and is fixed to the positioning hole 14 on the right first baffle 171.

[0129] Through the arrangement of the positioning holes on multiple baffles on the left side, the present invention can position and limit the pull ropes, ensuring that the pull ropes can pass through multiple baffles to reach the specified positions, so as to pull the middle baffle to move, for the purpose and effect of opening and closing the air inlet of the air conditioner.

[0130] In some embodiments,

[0131] The filter assembly 3 further includes a winding drum 33. The second rotating shaft 23 is disposed through the winding drum 33 to drive the winding drum 33 to rotate. The filter net 32 is wound around the winding drum 33. There are at least two winding drums 33 and at least two second rotating shafts 23. The winding drums 33 and the second rotating shafts 23 are arranged in one-to-one correspondence. One of the winding drums 33 is opposite to one side edge of the air inlet of the air conditioner, and one of the winding drums 33 is opposite to the other side edge of the air inlet of the air conditioner. One side edge of the filter net 32 is wound around the winding drum 33 on one side, and the other side edge of the filter net 32 is wound around the winding drum 33 on the other side.

[0132] Through the two winding drums arranged on both sides of the filter net and the two second rotating shafts arranged on both sides, the present invention can enable the second rotating shafts to cooperate with the winding drums, and drive the winding drums to move in different directions on both sides, thereby driving the filter net to wind towards one side, so as to achieve the purpose of controlling the movement of the filter net.

[0133] In some embodiments,

[0134] The filter net 32 includes multiple filter units, and the filter holes of at least two filter units are of different sizes. The motor 21 can be controlled to rotate to drive the filter net 32 to rotate on the winding drum 33, so that the size of the filter holes facing the air inlet of the air conditioner changes;

[0135] It further includes a detection component. The detection component can detect the air volume on both sides of the filter net 32, that is, detect the air volume before entering the filter net 32 through the air inlet of the air conditioner and the air volume after passing through the filter net 32, and can control the filter net 32 to rotate on the winding drum 33 according to the air volume before and after the filter net 32, so that the size of the filter holes facing the air inlet of the air conditioner changes.

[0136] The present invention also sets the filter screen to be composed of multiple filter units with different filter hole sizes, and controls the rotation of the filter screen on the reel, so as to realize the change of the size of the filter holes facing the air inlet of the air conditioner. And in cooperation with the structure for detecting the air volume on both sides of the filter screen, it can judge whether the filter screen is dirty or blocked according to the detected data. If it is judged that it is not dirty or blocked, the optimal gap of the filter screen is solved according to the operating state of the air conditioner, so as to reduce the air inlet resistance when meeting the filtering requirements, improve the refrigeration and heating performance, and reduce power consumption.

[0137] In some embodiments,

[0138] It further includes a cleaning component 41 (preferably an ultrasonic vibrator), a net receiving box 35 and a sterilization component 42. The cleaning component 41 and the sterilization component 42 are both arranged inside the net receiving box 35. When the filter screen 32 is dirty or blocked, the filter screen 32 can be controlled to be received into the net receiving box 35. The cleaning component 41 can clean the filter screen 32, and the sterilization component 42 can sterilize the filter screen 32.

[0139] When it is judged that the filter screen is dirty or blocked, the present invention can control the cleaning and sterilization of the filter screen, realizing an air conditioner structure integrating baffle, filtration, cleaning and sterilization.

[0140] The filter screen assembly of the present invention: The upper grid frame and the filter screen box cover adopt an integrated structure and are assembled with the lower grid frame through buckles, which is convenient for disassembly and assembly. The lower grid frame, the filter screen box and the panel body are integrated, which can effectively reduce the number of parts and the assembly complexity. The second rotating shaft is installed in the net box. After the filter screen is wound on the reel, it is installed on the second device. The reel rotates with the rotating shaft to realize the winding and unwinding of the net. The filter screen is spliced by multiple filter screens with different gaps, and the gap of the filter screen can be adjusted in real time according to the air volume inside and outside the filter screen measured by the distributed air volume sensor and the operating state of the air conditioner at this time, so that the air conditioner reaches the best operating state.

[0141] Cleaning component: The ultrasonic vibrator is fixed in the net receiving box with glue. When the air volume sensor measures that the air volume inside and outside does not match the standard value, it means that the filter screen needs to be cleaned. After the filter screen is completely wound into the net receiving box, it starts to vibrate and remove dust, which can clean the filter screen in the wound state well. After completion, the motor drives the filter screen to be released back into the net box for ultraviolet sterilization to achieve the best cleaning effect.

[0142] The invention points of the present invention are as follows: a protection device for the air inlet, an air conditioner and a control method are proposed. The protection device includes: a rigid baffle, a filter screen, a driving and cleaning component. By means of a sliding gear, the rigid baffle and the filter screen share the same set of driving motors for retracting and extending, and a rope drive is combined with a pulley to realize the folding and unfolding of the rigid baffle, and the filter screen with different gaps can be switched according to the actual situation; ultrasonic vibration dust removal combined with ultraviolet sterilization can better clean the filter screen. The present invention solves the problem of a large number of driving and transmission components in the prior art for air conditioners to meet the protection and dust removal functions.

[0143] The present invention also provides an air conditioner, which includes the aforementioned air inlet assembly of the air conditioner.

[0144] The present invention proposes a protection device for the air inlet and an air conditioner. By sharing the same set of driving motors for retracting and extending the rigid baffle and the filter screen, fewer driving and transmission components are used to achieve air inlet protection, with low cost, and the filter screen can be cleaned without disassembly and cleaning. The device mainly consists of: a panel body 0; a baffle assembly 1 (preferably rigid); a driving assembly 2; a filtering assembly 3; a cleaning component. The panel body serves as the main housing of the entire air conditioner, and each component is installed on it. The rigid baffle and the filter screen assembly are retracted and extended by the driving assembly, and the cleaning component is installed in the filter screen retracting and extending box.

[0145] In the present invention, by sharing the same set of driving motors for retracting and extending the rigid baffle and the filter screen, and using a rope drive combined with a pulley to realize the folding and unfolding of the rigid baffle, the protection effect is better. Compared with the existing separate driving and gear-rack transmission, fewer driving and transmission components are used, which is convenient to operate and has low cost; an ultrasonic vibration dust removal and ultraviolet sterilization device is installed in the filter screen placement box, which can better clean the filter screen without disassembly and cleaning, and solves the disadvantages of poor dust removal effect of the brush and a large number of driving and transmission components. Through a protection device control method proposed by the present invention, the rigid baffle is retracted and extended in a timely manner, and the filter screen with different gaps can be switched according to the actual situation by using the filter screen retracting and extending structure, ensuring that the air conditioner is in the optimal operating condition.

[0146] The present invention can solve the following technical problems:

[0147] 1. In the prior art, the number of driving and transmission components for protecting and dust removing the air inlet of the air conditioner is large, and the cost is relatively high.

[0148] 2. In the prior art, the filter screen needs to be removed for cleaning, which is inconvenient for disassembly and assembly, or the brush dust removal is easy to wear the filter screen, and the dust removal effect is poor.

[0149] 3. Provide a protection device control method to make the device operate more efficiently and intelligently, and keep the air conditioner in the best working state during operation.

[0150] Such as Figure 9, the present invention also provides a control method for the air inlet assembly of an air conditioner as described above, which includes:

[0151] A judgment step of judging whether the air conditioner is running;

[0152] A control step, if the air conditioner is running, controlling the baffle assembly to move to open the air inlet of the air conditioner, and after the baffle assembly opens the air inlet of the air conditioner, switching to controlling the filter assembly to move to adjust the filtering gap; if the air conditioner is closed, controlling the baffle assembly to move to close the air inlet of the air conditioner.

[0153] The control method of the present invention can drive the baffle assembly to open the air inlet of the air conditioner when the air conditioner is running, and drive the baffle assembly to close the air inlet of the air conditioner when it is closed, that is, the movement of the baffle assembly and the retraction and extension of the filter screen share a set of drive motors. Only a set of drive motors can effectively complete the drive movement of the baffle assembly and the retraction and extension effect of the filter assembly. Fewer drive and transmission components are used, the operation is convenient, and the cost is low. It solves the problems in the prior art that the number of drive and transmission components for protecting and removing dust from the air inlet of the air conditioner is large, the structure is complex, and the cost is relatively high.

[0154] In some embodiments,

[0155] It further includes a detection step. When the filter assembly 3 includes a filter screen 32, the air volumes on both sides of the filter screen 32 are detected, that is, the air volume entering the front of the filter screen 32 through the air inlet of the air conditioner and the air volume after passing through the filter screen 32 are detected;

[0156] In the judgment step, it is judged whether the filter screen 32 is dirty and blocked according to the magnitudes of the air volumes on both sides of the filter screen 32;

[0157] In the control step, when it is judged that it is dirty and blocked, the filter screen is controlled to perform a dust removal program, the cleaning component is controlled to remove dust from the filter screen, and the sterilization component is controlled to sterilize the filter screen; when it is judged that it is not dirty and blocked, the optimal filter screen gap is solved according to the operating state of the air conditioner, and the filter assembly is controlled to move to adjust the filtering gap to the optimal filter screen gap.

[0158] The control method of the present invention can judge whether the filter screen is dirty and blocked according to the detection data. If it is judged that it is not dirty and blocked, the optimal filter screen gap is solved according to the operating state of the air conditioner to reduce the air inlet resistance when meeting the filtering requirements, improve the refrigeration and heating performance, and reduce power consumption; if it is judged that it is dirty and blocked, the filter screen needs to be controlled to be cleaned and sterilized to improve the service life of the air conditioner.

[0159] The present invention provides a control method for a protection device. The rigid baffle of the air conditioner is initially in an unfolded state, which plays a role in protection and preventing dirt accumulation. When the controller issues an instruction for the air conditioner to start running, the electromagnet on one side is energized to make the sliding gear reach the designated position, and then the power is cut off. The motor drives the rotation of the third rotating shaft to retract the rigid baffle. Subsequently, each distributed air volume sensor collects the air volume at each point inside and outside the filter screen, combines with the current operating condition of the air conditioner, solves the optimal filter screen gap through a neural network, and then the electromagnet on the other side is energized to make the sliding gear engage with the gear of the second rotating shaft, and the rotating shaft rotates to select the filter screen with the corresponding gap, improving the operating efficiency of the air conditioner. When it is detected that the internal and external air volumes are lower than the standard value, it indicates that the filter screen is dusty and there is a dirt blockage phenomenon at this time. In this case, the air conditioner will clean during idle time. During cleaning, the baffle is unfolded, and the filter screen is completely wound into the winding box, and the ultrasonic vibrator is started to remove dust. After completion, the filter screen returns to the unwinding box for ultraviolet sterilization to ensure the normal use of the filter screen.

[0160] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
