Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and for example, to an air conditioner. Background Technology

[0002] Currently, air conditioners have become an indispensable electrical appliance, widely used in homes, businesses, and transportation, among other fields, for regulating air parameters such as cooling and heating. Related technology discloses an air conditioner including a casing and a heat exchanger. The casing has an air inlet and an air outlet, and the heat exchanger is located inside the casing. Air enters the casing through the air inlet and exchanges heat with the heat exchanger; the heat-exchanged air is then blown out through the air outlet.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] Dust, foreign objects, bacteria and other pollutants from the external environment can easily enter the casing through the air inlet, causing the air conditioner to blow out a large amount of pollutants when it blows out, resulting in a poor user experience.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides an air conditioner that solves the problem of pollutants easily entering the casing from the air inlet.

[0008] In some embodiments, the air conditioner includes:

[0009] The casing is equipped with an air inlet;

[0010] The dustproof device includes an air inlet guide plate assembly, which is rotatably disposed at the air inlet; wherein the air inlet guide plate assembly has an air inlet cover position, which corresponds to the air inlet guide plate assembly being rotated to cover the air inlet; and the air inlet guide plate assembly can be rotated from the air inlet cover position toward the outside of the housing to open the air inlet.

[0011] The air conditioner provided in this disclosure can achieve the following technical effects:

[0012] When the air inlet needs to be closed, flip the air inlet guide assembly to the air inlet cover position. In this position, the air inlet guide assembly covers the air inlet, preventing dust, foreign objects, bacteria, and other contaminants from the external environment from entering the casing, thus avoiding a large amount of contaminants being blown out of the air outlet during use. When the air inlet needs to be open, flip the air inlet guide assembly from the air inlet cover position to the outside of the casing. In this way, the air inlet guide assembly avoids obstructing the air inlet without occupying internal space, allowing air from the outside environment to enter the casing normally. Thus, the air inlet guide assembly can cover or guide the air inlet according to usage needs, effectively improving the user experience.

[0013] The above general description and the description below are exemplary and illustrative only and are not intended to limit this application. Attached Figure Description

[0045] The first embodiment of this application provides an air conditioner, which includes a housing 100 and a dustproof device. For example... Figure 1 As shown, the housing 100 is provided with an air inlet 110. The dustproof device includes a roller shutter assembly, which is rollable and uncoilable at the air inlet 110. The roller shutter assembly has a first region 201 and a second region 202 along the rolling direction. The first region 201 is closed, and the second region 202 is ventilated. Furthermore, the roller shutter assembly has a first rolling position and a second rolling position. The first rolling position corresponds to the first region 201 and is opposite to the air inlet 110, so as to cover the air inlet 110; the second rolling position corresponds to the second region 202 and is opposite to the air inlet 110, so as to open the air inlet 110. Here, opening the air inlet 110 means allowing outside air to enter the housing 100 from the air inlet 110.

[0046] In this embodiment, when the air inlet 110 needs to be closed, the roller shutter assembly is rolled up to the first rolled-up position. At this time, the first area 201 covers the air inlet 110, thereby preventing dust, foreign objects, bacteria, and other pollutants from the external environment from entering the housing 100 through the air inlet 110, thus avoiding a large amount of pollutants being blown out from the air outlet 120 during use. When the air inlet 110 needs to be opened, the roller shutter assembly is rolled up to the second rolled-up position. At this time, the second area 202 opens the air inlet 110, allowing air from the external environment to enter the housing 100 normally. In this way, the roller shutter assembly can cover or open the air inlet 110 according to usage needs, effectively improving the user experience.

[0047] Optionally, such as Figure 2 As shown, the roller blind assembly includes a first roller 210, a second roller 220, and a roller blind body 200. The first roller 210 is located on the first side of the air inlet 110. The second roller 220 is located on the second side of the air inlet 110. The first end of the roller blind body 200 is connected to the first roller 210, and the second end of the roller blind body 200 is connected to the second roller 220. When the first roller 210 is wound up and the second roller 220 is released, the roller blind body 200 moves towards the first roller 210; when the second roller 220 is wound up and the first roller 210 is released, the roller blind body 200 moves towards the second roller 220. Thus, through the coordinated operation of the first roller 210 and the second roller 220, the roller blind body 200 can move flexibly in both directions. This bidirectional movement allows for control of the roller blind body 200's position according to usage requirements.

[0048] Optionally, the roller blind body 200 is made of non-woven fabric. The density of the first zone 201 is sufficient to block air, while the density of the second zone 202 allows air to circulate.

[0049] Optionally, the second zone 202 is configured as a ventilation filter. While allowing airflow, it can also filter the passing air to some extent.

[0050] Optionally, the roller blind assembly further includes a first motor and a second motor. The drive shaft of the first motor is connected to the first roller 210 and drives the first roller 210 to rotate. The drive shaft of the second motor is connected to the second roller 220 and drives the second roller 220 to rotate.

[0051] In this embodiment, the movement of the roller shutter body 200 is achieved by two motors. For example, the first roller 210 is arranged above the air inlet 110, and the second roller 220 is arranged below the air inlet 110, as shown below. Figure 3 As shown. When the first motor and the second motor rotate clockwise, the first roller 210 retracts and the second roller 220 releases, at which time the roller blind body 200 moves upward. When the first motor and the second motor rotate counterclockwise, the first roller 210 releases and the second roller 220 retracts, at which time the roller blind body 200 moves downward.

[0052] Optionally, the roller blind assembly also includes a first motor and a spring. The drive shaft of the first motor is connected to the first roller 210 to drive the first roller 210 to rotate. The spring is connected to the second roller 220. When the roller blind body 200 moves toward the first roller 210, the spring stores elastic force; when the first roller 210 releases, the spring releases elastic force to drive the second roller 220 to roll up the roller blind body 200.

[0053] In this embodiment, the movement of the roller blind body 200 is achieved by a motor and a spring. For example, the first roller 210 is arranged above the air inlet 110, and the second roller 220 is arranged below the air inlet 110. When the first motor rotates clockwise, the first roller 210 retracts and the second roller 220 releases. At this time, the spring stores its elasticity, and the roller blind body 200 moves upward. When the first motor rotates counterclockwise, the first roller 210 releases, and the spring releases its elasticity, causing the second roller 220 to retract, and the roller blind body 200 moves downward.

[0054] Optionally, such as Figure 2 As shown, the roller shutter assembly also has a third region 203 along the rolling direction, and the third region 203 is configured as a sterilization filter. The roller shutter assembly has a third rolling position, which corresponds to the third region 203 and the air inlet 110, to sterilize the air flowing through the air inlet 110.

[0055] In this embodiment, when the roller shutter assembly moves to the third unwinding position, the third zone 203 can achieve a sterilization effect on the flowing air. Here, the third zone 203 can also allow air circulation. The difference between the third zone 203 and the second zone 202 lies in their functions. The third zone 203 is used to achieve a sterilization effect, while the second zone 202 is used to achieve a conventional filtration effect.

[0056] Optionally, the first area 201, the second area 202, and the third area 203 are set to different colors. For example, the first area 201 is gray, the second area 202 is white, and the third area 203 is green. In this way, when the roller shutter assembly moves to different rolling positions, the corresponding areas can be visually identified by color.

[0057] Optionally, the first region 201, the second region 202, and the third region 203 are arranged independently in sequence along the unwinding direction.

[0058] Optionally, the housing 100 also includes an air outlet 120, and the dustproof device further includes an air outlet guide plate assembly 420, such as... Figure 3 As shown. The air outlet guide plate assembly 420 is rotatably disposed at the air outlet 120. Furthermore, the air outlet guide plate assembly 420 has an air outlet covering position, which corresponds to the air outlet guide plate assembly 420 being rotated to cover the air outlet 120, and an air outlet avoidance position, which corresponds to the air outlet guide plate body being rotated to a plane perpendicular to the air outlet 120.

[0059] In this embodiment, when the air outlet 120 needs to be closed, the air outlet guide plate assembly 420 is flipped to the air outlet cover position. At this time, the air outlet guide plate assembly 420 covers the air outlet 120, thereby preventing dust, foreign objects, bacteria, and other pollutants from the external environment from entering the housing 100 through the air outlet 120. When the air inlet 110 needs to be opened, the air outlet guide plate assembly 420 is flipped to the air outlet avoidance position. At this time, the air outlet guide plate assembly 420 opens the air inlet 110, allowing air from the external environment to enter the housing 100 normally. Thus, under the action of the air outlet guide plate assembly 420, the air inlet 110 can be covered or opened according to usage needs, effectively improving the user experience.

[0060] Optionally, the air outlet guide plate assembly 420 includes an air outlet guide plate body and a second drive device. The second drive device includes an air outlet guide plate motor and a rotating shaft. The two sides of the air outlet guide plate body are mounted on the center of the air outlet 120 via the rotating shaft. The drive shaft of the air outlet guide plate motor is connected to the rotating shaft, thereby driving the air outlet guide plate body to rotate. In the air outlet covering position, the surface of the air outlet guide plate body covers the air outlet 120; in the air outlet avoidance position, the surface of the air outlet guide plate body avoids the air outlet 120. When the air outlet guide plate body is located in the center of the air outlet 120, the air resistance is minimized when it is rotated to the air outlet avoidance position.

[0061] In some embodiments, the air conditioner further includes a position detection device and a controller. The position detection device is used to detect the flip position of the air outlet guide vane assembly 420. The controller is electrically connected to the position detection device, the air outlet guide vane assembly 420, and the roller shutter assembly. Furthermore, the controller is configured to: control the air outlet guide vane assembly 420 to flip to an air outlet clearance position when the air conditioner is turned on, and control the roller shutter assembly to roll up to a second roll-up position after the air outlet guide vane assembly 420 has flipped to its correct position.

[0062] In this embodiment, when the air conditioner is turned on, the controller first controls the air outlet guide plate assembly 420 to rotate via the air outlet guide plate motor, and the position detection device transmits the position signal to the controller. After the air outlet guide plate assembly 420 rotates to the correct position, i.e., to the air outlet clearance position, the controller receives the corresponding position signal and controls the roller shutter assembly to roll up to the second roll-up position. In this way, air can enter the casing 100 from the air inlet 110, and after heat exchange, it is blown into the room from the air outlet 120, realizing the cooling and heating functions.

[0063] In some embodiments, such as Figure 1 As shown, the air conditioner also includes a heating device 140 and a controller. The heating device 140 is used to heat the air inside the casing 100. The controller is electrically connected to the heating device 140 and the air outlet guide assembly 420. Furthermore, the controller is configured to: activate the heating device 140 when the air conditioner is turned off; and, if the humidity inside the casing 100 is lower than a preset humidity value, control the air outlet guide assembly 420 to flip to the air outlet cover position and control the roller shutter assembly to roll up to the first roll-up position.

[0064] In this embodiment, after the air conditioner has been running for a period of time, condensate remains on the drip tray and evaporator, and the humidity inside the casing 100 is high. If not treated promptly, bacteria can easily grow. In this embodiment, dehumidification is performed inside the casing 100 when the unit is turned off. The controller activates the heating device 140 to heat the air inside the casing 100, thereby evaporating the condensate and reducing the humidity inside the casing 100. At this time, both the air inlet 110 and the air outlet 120 are open. When the humidity inside the casing 100 is lower than a preset humidity value, the controller controls the air outlet guide plate assembly 420 to flip to the air outlet cover position and controls the roller shutter assembly to roll up to the first roll-up position. At this time, both the air inlet 110 and the air outlet 120 are covered, isolating the space inside the casing 100 from the external environment. This prevents contaminants from entering the casing 100 after dehumidification, ensuring air quality.

[0065] A second embodiment of this application provides a method for controlling an air conditioner. The air conditioner includes a housing 100 and a dustproof device. The housing 100 has an air inlet 110 and an air outlet 120. The dustproof device includes a first cover and a second cover. The first cover is movably disposed at the air inlet 110 to cover or allow air to pass through. The second cover is movably disposed at the air outlet 120 to cover or allow air to pass through. Figure 4 As shown, the method for controlling the air conditioner includes:

[0066] S10: The controller acquires air parameters inside the housing;

[0067] S20: The controller controls the state of the first and second cover parts according to the air parameters inside the housing.

[0068] In this embodiment, the air conditioner includes a controller for controlling the states of a first cover and a second cover. When the first cover covers the air inlet 110, it prevents air from entering the casing 100 from the air inlet 110; when the second cover covers the air outlet 120, it prevents air from entering the casing 100 from the air outlet 120. When the first cover opens the air inlet 110, it allows air to enter the casing 100 from the air inlet 110; when the second cover opens the air outlet 120, it allows air inside the casing 100 to be blown out from the air outlet 120. Thus, after the controller obtains the air parameters inside the casing 100, it controls the first and second covers to close or open based on these air parameters, so as to facilitate further adjustment of the air parameters.

[0069] Optionally, in step S10, the controller acquires air parameters inside the housing, including: acquiring the air humidity inside the housing.

[0070] In this embodiment, a humidity detection device is installed inside the casing 100 and is electrically connected to the controller. The humidity detection device is used to detect the air humidity inside the casing 100 and transmit the humidity signal to the controller. After the air conditioner has been running for a period of time, condensate remains on the drip tray and evaporator, and the humidity inside the casing 100 is relatively high. If this is not addressed promptly, bacteria can easily grow.

[0071] Optionally, such as Figure 5 As shown, in step S20, the controller controls the state of the first and second cover parts according to the air parameters inside the housing, including:

[0072] S21: When the air humidity inside the casing is greater than or equal to the preset humidity, the controller controls the heating device and the fan to start, and controls the first cover and the second cover to open the air inlet and the air outlet respectively.

[0073] S22: When the air humidity inside the casing is lower than the preset humidity, the controller controls the heating device and the fan to stop, and controls the first cover and the second cover to cover the air inlet and the air outlet respectively.

[0074] In this embodiment, the air conditioner also includes a heating device 140 and a fan 150, both of which are disposed within the casing 100. The heating device 140 is used to heat the air inside the casing 100, and the fan 150 is used to circulate the air inside the casing 100. When the air humidity inside the casing 100 is greater than or equal to a preset humidity, it indicates that the air humidity is high. At this time, the controller controls both the heating device 140 and the fan 150 to start, and controls the first and second cover parts to open the air inlet 110 and the air outlet 120, respectively. Thus, under the action of the fan 150, air enters the casing 100 from the air inlet 110 and flows out from the air outlet 120, while the heating device 140 heats the air inside the casing 100, causing condensate to evaporate and reducing the air humidity inside the casing 100. As the air humidity gradually decreases and falls below the preset humidity level, the controller stops both the heating device 140 and the fan 150, and controls the first and second covering parts to cover the air inlet 110 and the air outlet 120, respectively. This prevents pollutants from entering the casing 100 and ensures the quality of the air output.

[0075] Optionally, the preset humidity is 50% RH.

[0076] Optionally, the first covering portion includes a roller shutter assembly, which is rollable and detachable at the air inlet 110. The roller shutter assembly has a first region 201, a second region 202, and a third region 203 along the rolling direction. The first region 201 is enclosed, the second region 202 is configured as a ventilation filter, and the third region 203 is configured as a sterilization filter. The roller shutter assembly has a first rolling position, a second rolling position, and a third rolling position. The first rolling position corresponds to the first region 201 and the air inlet 110, the second rolling position corresponds to the second region 202 and the air inlet 110, and the third rolling position corresponds to the third region 203 and the air inlet 110. The specific structure of the roller shutter assembly is detailed in the first embodiment and will not be repeated here.

[0077] Optionally, the second cover includes an air outlet guide plate assembly 420. The specific structure of the air outlet guide plate assembly 420 is detailed in the first embodiment and will not be repeated here.

[0078] Optionally, in step S10, the controller acquires air parameters inside the housing, including: acquiring the air quality index inside the housing.

[0079] In this embodiment, an air quality detection device is installed inside the housing 100 and is electrically connected to the controller. The air quality detection device is used to detect the air quality index (AQI) inside the housing 100 and transmit the AQI signal to the controller. After the air conditioner has been running for a period of time, the air inside the housing 100 often contains pollutants such as dust and bacteria. If these pollutants are not dealt with promptly, the air quality can easily deteriorate. Here, a higher AQI indicates worse air quality.

[0080] Optionally, such as Figure 6 As shown, in step S20, the controller controls the state of the first and second cover parts according to the air parameters inside the housing, including:

[0081] S23: When the air quality index inside the casing is greater than or equal to the preset index, the controller controls the fan to run forward for the first time, controls the second cover to cover the air outlet, and controls the roller shutter assembly to roll up to the first roll-up position.

[0082] S24: After the first time, the controller controls the roller shutter assembly to roll up to the second roll-up position, and controls the fan to run forward for the second time.

[0083] In this embodiment, the air conditioner also includes a fan 150, which is disposed inside the casing 100. When the fan 150 rotates forward, the airflow is directed towards the air outlet 120, and when it rotates in reverse, the airflow is directed towards the air inlet 110. If the air quality index inside the casing 100 is greater than or equal to a preset index, it indicates that the air quality is poor. At this time, the controller controls the fan 150 to run forward for a first time, controls the second cover to cover the air outlet 120, and controls the roller shutter assembly to roll up to the first roll-up position.

[0084] Since both the air outlet 120 and the air inlet 110 are covered, the space inside the casing 100 is isolated from the external environment. Rotating the fan 150 within this relatively enclosed space creates effective airflow disturbance, effectively blowing away accumulated dust inside the casing 100 and causing it to form floating dust. Furthermore, the controller immediately controls the roller shutter assembly to roll up to the second roll-up position, at which point the air inlet 110 is open. Because the fan 150 is rotating forward while the air outlet 120 is covered, the airflow blows towards the air outlet 120 and then flows back towards the air inlet 110. Thus, compared to the fan 150 reversing and the airflow directly blowing out from the air inlet 110, the airflow path in step S23 covers the area from the fan 150 to the air outlet 120, effectively carrying the floating dust inside the entire casing 100 towards the roller shutter assembly. Because the roller shutter assembly is located in the second unrolling position, the second zone 202 can filter the flowing air, causing dust to adhere to the ventilation filter and prevent it from entering the room. In summary, the first time is used to blow accumulated dust into floating dust, and the second time is used to blow the floating dust onto the ventilation filter.

[0085] Optionally, such as Figure 6 As shown, after step S24, which controls the fan 150 to run forward for the second time, the following steps are also included:

[0086] S25: After the second time, the controller starts the heating device, reverses the fan, and rolls the curtain assembly to the third position.

[0087] S26: When the air quality index inside the casing is lower than the preset index, the controller stops the fan and heating device, and controls the roller shutter assembly to roll up to the first rolling position.

[0088] In this embodiment, the air conditioner also includes a heating device 140, which is disposed inside the housing 100 for heating the air inside the housing 100. After dust removal in steps S23 and S24, the air inside the housing 100 is further sterilized. The controller controls the heating device 140 to start, controls the fan 150 to reverse, and controls the roller shutter assembly to roll up to the third position.

[0089] The heating device 140 raises the air temperature inside the casing 100, allowing condensate on components such as the heat exchanger and drip tray to evaporate. The fan 150 then blows the evaporated air, carrying bacteria, towards the roller shutter assembly. Since the roller shutter assembly is in the third unrolling position, the third area 203 can sterilize the flowing air, preventing bacteria-laden air from entering the room. Furthermore, because the fan 150 is rotating in reverse, the airflow flows directly to the air inlet 110. This shorter airflow path in step S25, compared to the fan 150 rotating forward and the airflow turning back from the air outlet 120 to the air inlet 110, allows for rapid airflow out of the casing 100, avoiding the problem of bacteria easily adhering during long airflow paths. As the air quality index gradually decreases and falls below a preset level, the controller stops both the heating device 140 and the fan 150, and controls the roller shutter assembly to roll up to the first unrolling position. This prevents contaminants from entering the casing 100, ensuring air quality.

[0090] Optionally, when the air conditioner is turned off, the air conditioner automatically executes S21 and S22 to dehumidify the inside of the casing 100.

[0091] Optionally, when the air conditioner is turned off, the air conditioner automatically executes S23 to S26 to remove dust and sterilize the inside of the casing 100.

[0092] The second embodiment also provides an apparatus for controlling an air conditioner, including a processor and a memory storing program instructions, the processor being configured to execute the above-described method for controlling the air conditioner when running the program instructions.

[0093] The second embodiment also provides an air conditioner, including the above-described device for controlling the air conditioner.

[0094] The second embodiment also provides a storage medium storing program instructions that, when executed, perform the above-described method for controlling an air conditioner.

[0095] The third embodiment of this application provides an air conditioner, including a housing 100 and a dustproof device. The housing 100 is provided with ventilation openings. Figure 7 and Figure 8 As shown, the dustproof device includes a diaphragm assembly that is detachably attached to the vent. Here, the vent includes an air inlet 110 and / or an air outlet 120.

[0096] In this embodiment, the diaphragm assembly primarily functions as a dustproof element during the production and transportation of the air conditioner. The diaphragm assembly isolates the space inside the casing 100 from the external environment. This prevents dust, foreign objects, bacteria, and other contaminants from entering the casing 100 through the vents, thus avoiding the emission of large amounts of contaminants during use. Once the air conditioner is in regular use, the user can simply remove the diaphragm assembly.

[0097] Optionally, a plurality of positioning holes 320 are provided around the periphery of the vent. The diaphragm assembly includes a diaphragm body 300, which includes a central region 301 and a surrounding region 302. Here, the portion corresponding to the area of ​​the vent is defined as the central region 301, and the portion extending beyond the edge of the vent and surrounding the central region 301 is defined as the surrounding region 302. Furthermore, the surrounding region 302 is provided with a plurality of positioning posts 310, and each positioning post 310 corresponds to a positioning hole 320. Figure 9 As shown, the positioning post 310 includes a post body 311 and a ball head 312. The first end of the post body 311 passes through the positioning hole 320, and the ball head 312 is disposed at the first end of the post body 311, and the diameter of the ball head 312 is larger than the diameter of the positioning hole 320.

[0098] In this embodiment, under the action of the positioning post 310, the post 311 passes through the positioning hole 320 and determines the relative position of the diaphragm body 300 and the vent. Furthermore, since the diameter of the ball head 312 is larger than the diameter of the positioning hole 320, the positioning post 310 cannot be pulled out of the positioning hole 320, thus allowing the diaphragm body 300 to be fixedly installed at the vent.

[0099] Optionally, the positioning post 310 is formed by the inward deformation of the diaphragm body 300 toward the positioning hole 320.

[0100] In this embodiment, the positioning post 310 is not an independently installed structure, but is formed by the diaphragm body 300 itself. Figure 11 and Figure 12 As shown, the first heating air curtain 350 blows the surrounding area 302 of the diaphragm body 300 toward the positioning hole 320. Under the force of the airflow and the heating effect of the first heating air curtain 350, the portion of the surrounding area 302 corresponding to the positioning hole 320 deforms inward toward the positioning hole 320, and the portion that adheres to the hole wall of the positioning hole 320 is called a column 311. Furthermore, after this portion passes through the positioning hole 320, it is no longer restricted by the hole wall. At this time, the portion passing through the positioning hole 320 forms a spherical head 312 with a diameter larger than the hole diameter of the positioning hole 320 under the action of airflow and thermal expansion.

[0101] Optionally, the membrane body 300 is made of low-density polyethylene (LDPE). LDPE is easy to process and can be manufactured into membranes of different thicknesses and specifications through various processes such as blow molding and casting. Furthermore, LDPE membranes have good flexibility and extensibility.

[0102] Optionally, a dummy break line 340 is provided in the middle region 301 of the diaphragm body 300. The dummy break line 340 is formed by tool imprinting, and the diaphragm body 300 at the dummy break line 340 is the easiest to break. In this way, when the air conditioner is in use, the user can easily break the diaphragm body 300 through the dummy break line 340 and then pull the diaphragm body 300 off from the vent.

[0103] Optionally, such as Figure 10 As shown, the diaphragm assembly also includes an easy-tear strip 330, which is disposed inside all the positioning holes 320. The easy-tear strip 330 has multiple adhesive segments 331, each corresponding to one positioning hole 320; the adhesive segments 331 are constructed in an arc shape, with the inner arc surface facing the positioning hole 320. The ball head 312 of the positioning post 310 is bonded to the inner arc surface of the adhesive segment 331 after formation.

[0104] In this embodiment, after the diaphragm body 300 is pulled off from the vent, the positioning posts 310 may get stuck in the positioning holes 320 or fall into the vent. With a large number of positioning posts 310, cleaning them one by one is quite tedious. This embodiment, by providing an easy-tear strip 330, allows all positioning posts 310 to be removed at once.

[0105] Specifically, the arc-shaped design of the adhesive section 331 ensures the space for the formation of the ball head 312, while also limiting the diameter of the ball head 312. After the diaphragm body 300 passes through the positioning hole 320, under the action of the first heating air curtain 350, the part that passes through forms the ball head 312 within the inner arc surface of the adhesive section 331. Furthermore, an adhesive structure is provided on the inner arc surface, and the ball head 312 is adhered to the inner arc surface after formation. Here, by controlling the wind speed and temperature of the first heating air curtain 350, the formed ball head 312 is made to fit the inner arc surface. In this embodiment, an easy-tear strip 330 is used to adhere to the inside of all the positioning holes 320. After the diaphragm body 300 is torn off, the positioning post 310 is only adhered to the adhesive section 331. In this way, all the positioning posts 310 can be removed from the inside of the positioning holes 320 simply by tearing off the easy-tear strip 330, which is very convenient.

[0106] Optionally, such as Figure 7As shown, the length of the virtual break line 340 is denoted as L1. After the central region 301 of the diaphragm body 300 covers the vent, the surrounding region 302 of the diaphragm body 300 and the enclosure of the housing 100 form a plate surface that conforms to the vent, and the length of the conforming portion is denoted as L2. Furthermore, 1 < L1 / L2 < 10.

[0107] In this embodiment, the purpose of fitting the surrounding area 302 of the diaphragm body 300 with the corresponding plate surface of the housing 100 is to improve the connection strength between the diaphragm body 300 and the housing 100. The L1 / L2 ratio is designed to prevent the middle area 301 from accidentally breaking due to the excessive length of the dummy break line 340, while also ensuring that the user can easily tear the diaphragm body 300 off the housing 100 after breaking the dummy break line 340. Here, L2 can also be regarded as the width of the surrounding area 302.

[0108] Optionally, such as Figure 7 As shown, the ventilation opening includes an air outlet 120, which is enclosed by multiple air outlet frame edges 121 of the housing 100. Positioning holes 320 are arranged on the plate surface of the air outlet frame edges 121. Furthermore, the plate surface of the air outlet frame edges 121 is perpendicular to the plane where the air outlet 120 is located, and the surrounding area 302 of the diaphragm body 300 is in contact with the plate surface of the air outlet frame edges 121.

[0109] In this embodiment, the air outlet 120 is enclosed by multiple air outlet frame edges 121, which enhances the structural strength of the air outlet 120. Arranging the positioning holes 320 on the plate surface of the air outlet frame edges 121 facilitates the accurate fixing of the diaphragm assembly to the air outlet frame edges 121 during installation.

[0110] Optionally, such as Figure 8 As shown, the ventilation opening includes an air inlet 110, which is enclosed by multiple air inlet frame edges 111 of the housing 100. Positioning holes 320 are arranged on the plate surface of the air inlet frame edges 111. Furthermore, the plate surface of the air inlet frame edges 111 is parallel to the plane where the air inlet 110 is located, and the surrounding area 302 of the diaphragm body 300 is in contact with the plate surface of the air inlet frame edges 111.

[0111] In this embodiment, the air inlet 110 is enclosed by multiple air inlet frame edges 111, which enhances the structural strength of the air inlet 110. Arranging the positioning holes 320 on the plate surface of the air inlet frame edges 111 facilitates the accurate fixing of the diaphragm assembly to the air inlet frame edges 111 during installation.

[0112] like Figure 14 As shown, the third embodiment also provides a method for covering an air conditioner vent with a film, for removably covering the vent of the air conditioner with a film assembly, including:

[0113] S30: The middle area of ​​the diaphragm body covers the vent, and the surrounding area of ​​the diaphragm body extends beyond the edge of the vent.

[0114] S31: The first heating air curtain blows air towards the outer surface of the diaphragm body, so that the surrounding area is deformed into the inner side of the positioning hole to form a positioning post.

[0115] S32: A cutter is used to create a dummy break line in the middle region of the diaphragm body;

[0116] S33: A second heated air curtain is used to blow air away from the outer surface of the diaphragm body to flatten the middle area of ​​the diaphragm body.

[0117] In this embodiment, a film coating process is implemented during the production of the air conditioner. After the diaphragm body 300 covers the vent, the surface facing the inside of the vent is called the inner surface, and the surface facing the outside of the air outlet 120 is called the outer surface.

[0118] In step S30, after the middle region 301 of the diaphragm body 300 is placed over the vent, the area of ​​the middle region 301 corresponds to the area of ​​the vent, and the surrounding region 302 extends beyond the edge of the vent. The extended portion is used to fit against the housing 100.

[0119] For step S31, as follows Figure 11 As shown, the first heating air curtain 350 blows air towards the outer surface of the diaphragm body 300, causing the middle region 301 of the diaphragm body 300 to abut against the vent, and causing the surrounding region 302 to deform inward toward the positioning hole 320. Under the action of the airflow and heating from the first heating air curtain 350, the portion of the surrounding region 302 corresponding to the positioning hole 320 deforms inward toward the positioning hole 320, and the portion abutting against the hole wall of the positioning hole 320 is called a column 311. Furthermore, after this portion passes through the positioning hole 320, it is no longer restricted by the hole wall. At this time, the portion passing through the positioning hole 320, under the action of airflow and thermal expansion, forms a spherical head 312 with a diameter larger than the hole diameter of the positioning hole 320, such as... Figure 12 As shown. Because the diameter of the ball head 312 is large, the positioning post 310 cannot be pulled out to the outside of the positioning hole 320, so that the diaphragm body 300 can be fixedly installed at the vent.

[0120] In step S32, a dummy break line 340 is formed by pressing a tool into the middle region 301 of the diaphragm body 300. The diaphragm body 300 at the dummy break line 340 is the easiest to break. In this way, when the air conditioner is installed and put into use, the user can easily break the diaphragm body 300 through the dummy break line 340 and then pull the diaphragm body 300 off from the vent.

[0121] Regarding step S33, under the action of the first heating air curtain 350 in step S31, the middle region 301 of the diaphragm body 300 will slightly indent towards the inside of the vent due to the wind pressure. In this step, as... Figure 13 As shown, air is blown from the outer surface of the diaphragm body 300 away from the second heated air curtain 360, and the slightly concave middle area 301 is moved to the outside of the vent under the action of air pressure, thereby flattening it.

[0122] Optionally, step S30, before covering the vent with the middle region 301 of the diaphragm body 300, further includes:

[0123] Adhere the easy-tear strip 330 to the inside of all the positioning holes 320.

[0124] In this embodiment, the structure of the easy-tear strip 330 is detailed above. By setting the easy-tear strip 330, after the positioning post 310 is formed, the ball head 312 is bonded to the inner arc surface of the bonding section 331. In this way, during disassembly, all positioning posts 310 can be removed from the inside of the positioning hole 320 simply by tearing off the easy-tear strip 330, which is very convenient.

[0125] Optionally, the blowing temperature of the first heating air curtain 350 is 70℃-95℃.

[0126] Optionally, the blowing speed of the first heating air curtain 350 is 5m / s-10m / s.

[0127] Optionally, the blowing temperature of the second heating air curtain 360 is 50℃-70℃.

[0128] Optionally, the blowing speed of the second heating air curtain 360 is less than the blowing speed of the first heating air curtain 350.

[0129] Here, the function of the first heating air curtain 350 is to form the positioning post 310 of the diaphragm body 300. Since the deformation of the diaphragm body 300 is relatively large, the required temperature and air velocity are greater than those of the second heating air curtain 360. The function of the second air curtain is only to flatten the slightly concave part of the middle region 301 of the diaphragm body 300, so the required temperature and air velocity are lower.

[0130] Optionally, the first heating air curtain 350 consists of airflow from one or more sets of nozzles. Furthermore, when multiple positioning holes 320 are located on different planes, positioning holes 320 on the same plane use nozzles with corresponding orientations for airflow.

[0131] For example, such as Figure 7As shown, four air outlet frame edges 121 enclose a rectangle, and the plate surfaces of the air outlet frame edges 121 are all perpendicular to the plane where the air outlet 120 is located. Each air outlet frame edge 121 has a positioning hole 320 on its plate surface. At this time, four sets of nozzles are used to blow air towards the upper, lower, left, and right sides of the air outlet 120 air outlet frame edges 121 respectively, and one set of nozzles is used to blow air towards the middle area 301.

[0132] For example, such as Figure 8 As shown, the four air inlet frame edges 111 form a rectangle, and the plate surfaces of the air inlet frame edges 111 are all parallel to the plane where the air inlet 110 is located. Each air inlet frame edge 111 has a positioning hole 320 on its plate surface. At this time, the positioning hole 320 and the middle area 301 can be regarded as being on the same plane, and a set of nozzles can be used to blow air towards the plane where the air inlet 110 is located.

[0133] Optionally, the second heating air curtain 360 consists of airflow blown out by nozzles.

[0134] Optionally, the air inlet 110 of the air conditioner is equipped with both a diaphragm assembly and a roller shutter assembly, with the diaphragm assembly located outside the roller shutter assembly. The roller shutter assembly can be used normally after the diaphragm assembly is removed. In this way, the diaphragm assembly can prevent dust during the production and transportation of the air conditioner, while the roller shutter assembly can prevent dust, remove dust, or sterilize during the use of the air conditioner.

[0135] Optionally, the air outlet 120 of the air conditioner is equipped with both a diaphragm assembly and an air outlet guide plate assembly 420, with the diaphragm assembly located outside the air outlet guide plate assembly 420. The air outlet guide plate assembly 420 can be used normally after the diaphragm assembly is removed. In this way, the diaphragm assembly can prevent dust during the production and transportation of the air conditioner, and the air outlet guide plate assembly 420 can prevent dust during the use of the air conditioner.

[0136] The fourth embodiment of this application provides an air conditioner, including a housing 100 and a dustproof device. The housing 100 is provided with an air inlet 110. Figure 15 As shown, the dustproof device includes an air inlet guide plate assembly, which is rotatably disposed at the air inlet 110. The air inlet guide plate assembly has an air inlet cover position, which corresponds to the air inlet guide plate assembly being rotated to cover the air inlet 110. Furthermore, the air inlet guide plate assembly can be rotated from the air inlet cover position toward the outside of the housing 100 to open the air inlet 110.

[0137] In this embodiment, when the air inlet 110 needs to be closed, the air inlet guide plate assembly is flipped to the air inlet cover position. At this time, the air inlet guide plate assembly covers the air inlet 110, thereby preventing dust, foreign objects, bacteria, and other pollutants from the external environment from entering the housing 100 through the air inlet 110, thus avoiding a large amount of pollutants being blown out from the air outlet 120 during use. When the air inlet 110 needs to be opened, the air inlet guide plate assembly is flipped from the air inlet cover position to the outside of the housing 100. At this time, the air inlet guide plate assembly can both avoid the air inlet 110 and not occupy the internal space of the housing 100, allowing air from the external environment to enter the housing 100 normally. Thus, under the action of the air inlet guide plate assembly, the air inlet 110 can be covered or opened according to usage needs, effectively improving the user experience.

[0138] Optionally, the air inlet guide plate assembly includes an air inlet guide plate body 400 and a first driving device. The surface of the air inlet guide plate body 400 corresponds to the air inlet 110. The first driving device includes an air inlet guide plate motor and a connector 410. A first end of the connector 410 is connected to the air inlet guide plate motor, and a second end of the connector 410 is connected to a first side of the air inlet guide plate body 400. When the air inlet guide plate motor rotates, it drives the air inlet guide plate body 400 to rotate via the connector 410. Thus, the rotation angle of the air inlet guide plate body 400 can be adjusted by controlling the air inlet guide plate motor.

[0139] Optionally, such as Figure 16 As shown, the connector 410 includes a first connecting arm 411 and a second connecting arm 412. The first end of the first connecting arm 411 is connected to the drive shaft of the air inlet guide plate motor. The first end of the second connecting arm 412 is connected to the second end of the first connecting arm 411, and the second end of the second connecting arm 412 is connected to the first side of the air inlet guide plate body 400. Furthermore, the second connecting arm 412 and the first connecting arm 411 form an angle α, where 0 < α < 180°, and at the air inlet cover position, the opening of the angle α faces outwards from the air inlet 110.

[0140] In this embodiment, the connector 410 consists of two connecting arms, which helps the air inlet guide plate body 400 to be more stable and less prone to shaking during the flipping process. With the included angle α, the first connecting arm 411 and the second connecting arm 412 form a V-shape. This included angle design helps the connector 410 to more effectively transmit the power of the air inlet guide plate motor when driving the air inlet guide plate body 400 to flip, and also forms a larger flipping angle.

[0141] Optionally, the first connecting arm 411 extends in a straight line.

[0142] Optionally, the second connecting arm 412 extends along an arc. Furthermore, when the second connecting arm 412 is arc-shaped, the angle between the line connecting the two ends of the second connecting arm 412 and the first connecting arm 411 is denoted as α, as follows: Figure 16 As shown.

[0143] Optionally, the air inlet guide plate assembly has an air inlet avoidance position, which corresponds to the air inlet guide plate body 400 being flipped to a plane perpendicular to the air inlet 110.

[0144] In this embodiment, the air inlet guide plate assembly can avoid the air inlet 110 by flipping it from the air inlet cover position toward the outside of the housing 100, and the position where the air inlet guide plate body 400 is flipped to be perpendicular to the plane where the air inlet 110 is located is defined as the air inlet avoidance position. Here, through the structural design of the first connecting arm 411 and the second connecting arm 412, the air inlet guide plate body 400 can be completely flipped to the outside of the air inlet 110.

[0145] Optionally, such as Figure 17 As shown, the first side of the air inlet guide plate body 400 is close to the upper side of the air inlet 110, and the second side of the air inlet guide plate assembly can be flipped upward to the air inlet avoidance position. Furthermore, at the air inlet avoidance position, the first side and the second side of the air inlet guide plate body 400 are respectively located on both sides of the plane where the air inlet 110 is located.

[0146] In this embodiment, during the process of the air inlet guide plate assembly flipping from the air inlet cover position to the air inlet avoidance position, the upper edge of the air inlet 110 is located within the included angle α of the two connecting arms. Since the first side and the second side of the air inlet guide plate body 400 are located on opposite sides of the plane where the air inlet 110 is located, that is, the first side of the air inlet guide plate body 400 is located on the front side of the air inlet 110 and the second side of the air inlet guide plate body 400 is located on the rear side of the air inlet 110, the reserved space on the rear side of the air inlet 110 of the housing 100 can be reduced.

[0147] Optionally, such as Figure 17 As shown, the housing 100 includes a top plate 130. At the air inlet clearance position, the height of the air inlet guide plate body 400 is greater than the height of the top plate 130. In this way, there is a gap between the air inlet guide plate body 400 and the top plate 130, and the airflow above the top plate 130 can flow through this gap to the air inlet 110, which helps to increase the air intake volume.

[0148] Optionally, the housing 100 also includes an air outlet 120, and the dustproof device further includes an air outlet guide plate assembly 420. The air outlet guide plate assembly 420 is rotatably mounted at the air outlet 120, and has an air outlet covering position and an air outlet avoidance position. The air outlet covering position corresponds to the air outlet guide plate assembly 420 being rotated to cover the air outlet 120, and the air outlet avoidance position corresponds to the air outlet guide plate being rotated to a position perpendicular to the plane of the air outlet 120. Thus, under the action of the air outlet guide plate assembly 420, the air inlet 110 can be covered or guided according to usage requirements, effectively improving the user experience.

[0149] Optionally, the air outlet guide plate assembly 420 includes an air outlet guide plate body and a second drive device. The second drive device includes an air outlet guide plate motor and a rotating shaft. The two sides of the air outlet guide plate body are mounted on the center of the air outlet 120 via the rotating shaft. The drive shaft of the air outlet guide plate motor is connected to the rotating shaft, thereby driving the air outlet guide plate body to rotate. In the air outlet covering position, the surface of the air outlet guide plate body covers the air outlet 120; in the air outlet avoidance position, the surface of the air outlet guide plate body avoids the air outlet 120. When the air outlet guide plate body is located in the center of the air outlet 120, the air resistance is minimized when it is rotated to the air outlet avoidance position.

[0150] In some embodiments, the air conditioner further includes a position detection device and a controller. The position detection device is used to detect the flip position of the air outlet guide vane assembly 420. The controller is electrically connected to the position detection device, the air inlet guide vane assembly, and the air outlet guide vane assembly 420. Furthermore, the controller is configured to: control the air outlet guide vane assembly 420 to flip to an air outlet clearance position when the air conditioner is turned on, and control the air inlet guide vane assembly to flip to an air inlet clearance position after the air outlet guide vane assembly 420 has flipped to its correct position.

[0151] In this embodiment, when the air conditioner is turned on, the controller first controls the air outlet guide plate assembly 420 to rotate via the air outlet guide plate motor, and the position detection device transmits the position signal to the controller. After the air outlet guide plate assembly 420 rotates to the correct position, i.e., to the air outlet clearance position, the controller receives the corresponding position signal and controls the air inlet guide plate assembly to rotate to the air inlet clearance position. In this way, air can enter the casing 100 from the air inlet 110, and after heat exchange, it is blown into the room from the air outlet 120, realizing the cooling and heating functions.

[0152] In some embodiments, the air conditioner further includes a heating device 140 and a controller. The heating device 140 is used to heat the air inside the casing 100. The controller is electrically connected to the heating device 140, the air inlet guide plate assembly, and the air outlet guide plate assembly 420. Furthermore, the controller is configured to: activate the heating device 140 when the air conditioner is turned off, and, if the humidity inside the casing 100 is less than a preset humidity value, control the air inlet guide plate assembly and the air outlet guide plate assembly 420 to respectively cover the air inlet 110 and the air outlet 120.

[0153] In this embodiment, after the air conditioner has been running for a period of time, condensate remains on the drip tray and evaporator, and the humidity inside the casing 100 is high. If not treated promptly, bacteria can easily grow. In this embodiment, dehumidification is performed inside the casing 100 when the unit is turned off. The controller activates the heating device 140 to heat the air inside the casing 100, thereby evaporating the condensate and reducing the humidity inside the casing 100. At this time, both the air inlet 110 and the air outlet 120 are open. When the humidity inside the casing 100 is lower than a preset humidity value, the controller controls the air outlet guide plate assembly 420 to flip to the air outlet cover position and the air inlet guide plate assembly to flip to the air inlet cover position. At this time, both the air inlet 110 and the air outlet 120 are covered, isolating the space inside the casing 100 from the external environment. This prevents contaminants from entering the casing 100 after dehumidification, ensuring air quality.
