Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air conditioning technology, specifically to a panel device and an air conditioner. Background Technology

[0002] In related technologies, some openings in the panel frame are designed to be relatively large, resulting in larger and heavier panel components. In such cases, a single stepper motor is generally insufficient to rotate the panel component, requiring two or more stepper motors. However, multiple stepper motors may become out of sync after operating for a period of time, causing the panel device to operate erratically, producing abnormal noise, and even leading to panel distortion that prevents the panel component from completely closing the openings. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a panel device that, by setting a zero-point limiting structure, facilitates synchronization among multiple stepper motors, thereby helping to avoid problems such as abnormal noise or panel distortion caused by the panel device not running smoothly.

[0004] To this end, this application provides a panel device, including: a panel frame having an opening; a panel assembly rotatably connected to the panel frame and configured to open and close the opening; and a plurality of driving mechanisms connected to the panel assembly and configured to drive the panel assembly to reciprocate between an open position (opening the opening) and a closed position (closing the opening); the driving mechanism includes a stepper motor and a zero-point limiting structure, the zero-point limiting structure being configured to restrict the corresponding stepper motor from continuing to rotate when the corresponding stepper motor resets to the zero-point position.

[0005] This application also provides an air conditioner, including a panel device and a control device as described in any of the above embodiments, wherein the control device is electrically connected to a plurality of the stepper motors and is configured to control the plurality of stepper motors.

[0006] The panel device and air conditioner provided in this application embodiment, by setting a zero-point limiting structure, help reduce the step difference between different stepper motors, so that the stepper motor can achieve synchronization between multiple stepper motors with a relatively small number of oversteps, solve the problem of asynchrony between multiple stepper motors, and does not affect the service life of the stepper motor.

[0007] Specifically, because the zero-point limit structure can restrict the stepper motor from continuing to rotate when it resets to the zero position, as long as each stepper motor is ensured to reset to the position where it can no longer rotate after each use (due to the restriction of the zero-point limit structure), it can be guaranteed that each stepper motor resets to the zero position every time, thereby reducing the probability of asynchronous problems and also helping to reduce the step difference between asynchronous stepper motors. Similarly, as long as each stepper motor is ensured to reset to the position where it can no longer rotate before each use (due to the restriction of the zero-point limit structure), it can be guaranteed that each stepper motor resets to the zero position, and then rotates the set number of steps from that position, which also helps to reduce the probability of asynchronous problems and also helps to reduce the step difference between asynchronous stepper motors. In this way, by limiting the step difference between asynchronous stepper motors through the zero-point limit structure, the step difference can be kept within a very small range, and synchronization between multiple stepper motors can be easily achieved with fewer oversteps. Since the number of oversteps is small, it will not cause the motor stall time to be too long, and therefore will not affect the service life of the stepper motor. Attached Figure Description

[0032] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0033] This application provides a panel device and an air conditioner. The panel device can be used in an embedded air conditioner to solve the problem of oil and steam easily entering the return air vent when the embedded air conditioner is used as a kitchen air conditioner. Accordingly, the opening 11 of the panel frame 1 is the return air vent, and the panel assembly 2 is the return air panel assembly. To ensure sufficient airflow, the return air vent is designed to be relatively large, therefore the return air panel assembly is also relatively large and heavy, requiring multiple stepper motors 31 to drive it. However, this leads to the problem of the multiple stepper motors 31 being out of sync. The panel device provided in this application can effectively solve this problem.

[0034] Of course, this panel device can also be used in other scenarios. For example, panel assembly 2 can also be an air outlet panel assembly, with opening 11 as an air outlet; or, panel assembly 2 can be an inspection panel, with opening 11 as an inspection port; or, opening 11 can be an opening 11 for other purposes, and panel assembly 2 can be a panel assembly 2 for other purposes. Devices including this panel device are not limited to recessed air conditioners; they can also be non-recessed air conditioners, or other devices such as air purifiers.

[0035] Built-in air conditioners can be used in kitchens, but also in other locations. They can be either a single unit or the indoor unit of a split-type air conditioner. Built-in air conditioners can be installed within the ceiling (e.g., in a suspended ceiling) or within the wall. The following explanation uses a panel-mounted air conditioner, specifically a built-in kitchen air conditioner installed within a suspended ceiling, as an example.

[0036] like Figure 1 , Figure 2 , Figure 13 and Figure 14As shown, this application embodiment provides a panel device, including: a panel frame 1, a panel assembly 2, and a plurality of driving mechanisms 3.

[0037] The panel frame 1 has an opening 11. The opening 11 is a return air vent.

[0038] The panel assembly 2 is rotatably connected to the panel frame 1 and is configured to open and close the opening 11.

[0039] Multiple drive mechanisms 3 are connected to the panel assembly 2 and configured to drive the panel assembly 2 to reciprocate between the open position of the opening 11 and the closed position of the opening 11. Each drive mechanism 3 includes a stepper motor 31 and a zero-point limiting structure. The zero-point limiting structure is configured to restrict the corresponding stepper motor 31 from continuing to rotate when it resets to the zero-point position. The zero-point limiting structure and the corresponding stepper motor 31 refer to the zero-point limiting structure and the stepper motor 31 belonging to the same drive mechanism 3.

[0040] Multiple drive mechanisms 3 can be spaced apart along the extension direction of the rotation axis of the panel assembly 2, and jointly provide driving force to the panel assembly 2. For example, there can be two drive mechanisms 3, which can be connected to the two end regions (regions near the edge, not necessarily the two ends) of the panel assembly 2 respectively. There can also be three drive mechanisms 3, where two drive mechanisms 3 can be connected to the two end regions of the panel assembly 2 respectively, and the other drive mechanism 3 can be connected to the middle of the panel assembly 2.

[0041] The panel device provided in this application embodiment can open or close the opening 11 (i.e., the return air vent) on the panel frame 1 via the panel assembly 2. Thus, when the air conditioner needs to be turned on, multiple drive mechanisms 3 can drive the panel assembly 2 to open the opening 11, such as... Figure 1 , Figure 8 and Figure 9 As shown, this allows indoor airflow to enter the air conditioner through the return air vent, ensuring normal operation. When the air conditioner is not needed, multiple drive mechanisms 3 can drive the panel assembly 2 to close the opening 11 (e.g., Figure 10 and Figure 11 As shown, oil stains and steam can only remain outside the air conditioner, preventing oil stains and steam in the kitchen from entering the air conditioner through the return air vent. This helps to extend the service life of the oil filter and evaporator, and also helps to extend the cleaning cycle of the air conditioner, thereby improving the user experience and the reliability of the air conditioner.

[0042] Furthermore, by reasonably controlling the opening angle of panel assembly 2 during air conditioner operation (e.g., less than 90°), such as... Figure 1 and Figure 2As shown, while ensuring the return air volume of the air conditioner, it can effectively reduce the amount of oil entering the equipment, because the panel assembly 2 itself can intercept some of the oil, causing the oil to deposit on the panel assembly 2.

[0043] The issue of multiple stepper motors 31 being out of sync can be addressed through a power-on overstep reset design. This involves multiple stepper motors 31 simultaneously closing and overstepping during initial power-on. The received rotation step command exceeds the actual operating step range of the stepper motor 31. After execution, the current position is designated as the zero point. Subsequently, each stepper motor 31 operates within the predetermined step range. However, this approach has several drawbacks: Each zero-point reset requires a power-off and power-on process to achieve the reset via the power-on overstep reset design. This power-off and power-on operation is user-mandated and complex. Furthermore, the large number of oversteps (to ensure each stepper motor 31 resets to the zero point) leads to prolonged motor stall time, potentially reducing the lifespan of the stepper motors 31 over time.

[0044] The panel device provided in this application embodiment, by setting a zero-point limiting structure, helps to reduce the step difference between different stepper motors 31, so that the stepper motor 31 can achieve synchronization between multiple stepper motors 31 with a relatively small number of oversteps, thus solving the problem of asynchrony between multiple stepper motors 31, without affecting the service life of the stepper motor 31.

[0045] Specifically, since the zero-point limiting structure can restrict the stepper motor 31 from continuing to rotate when it resets to the zero-point position, as long as each stepper motor 31 is ensured to reset to the position where it cannot rotate further after each use (due to the restriction of the zero-point limiting structure), it can be guaranteed that each stepper motor 31 resets to the zero-point position every time, thereby reducing the probability of asynchronous problems and also helping to reduce the step difference between asynchronous stepper motors 31. Similarly, as long as each stepper motor 31 is ensured to reset to the position where it cannot rotate further before each use (due to the restriction of the zero-point limiting structure), it can be guaranteed that each stepper motor 31 resets to the zero-point position, and then rotates the set number of steps from that position, which also helps to reduce the probability of asynchronous problems and also helps to reduce the step difference between asynchronous stepper motors 31. In this way, by limiting the step difference between asynchronous stepper motors 31 through the zero-point limiting structure, the step difference can be limited to a very small range, and synchronization between multiple stepper motors 31 can be easily achieved with fewer oversteps. Because the number of oversteps is small, it will not cause the motor to stall for too long, and therefore will not affect the service life of the stepper motor 31.

[0046] In some exemplary embodiments, the drive mechanism 3 further includes a swing element 32 connected to the stepper motor 31, and the swing element 32 is connected to the panel assembly 2.

[0047] The zero-point limit structure is configured to engage with the swing element 32 to stop the rotation of the drive mechanism 3 to the closed position. Figure 15 , Figure 18 and Figure 19 As shown, this is to limit the stepper motor 31 from continuing to rotate, so that the stepper motor 31 is reset to the zero position.

[0048] In other words, the zero-point limiting structure does not directly restrict the stepper motor 31 from continuing to rotate, but indirectly restricts the stepper motor 31 from continuing to rotate by restricting the rotation of the swing component 32, which is connected to the stepper motor 31 for transmission. This makes it easier to reasonably set the structural form and position of the zero-point limiting structure.

[0049] Of course, the zero-point limit structure can also be directly matched with the stepper motor 31. For example, when the stepper motor 31 is reset and rotated to the zero position, it can be matched with the output shaft of the stepper motor 31 to limit the stepper motor 31 from continuing to rotate.

[0050] In some exemplary embodiments, the drive mechanism 3 further includes a stepper motor housing 33 disposed on the panel frame 1, such as Figure 15 and Figure 20 As shown. Stepper motor 31 is mounted in stepper motor housing 33, and zero-point limiting structure is located in stepper motor housing 33.

[0051] Of course, the zero-point limit structure can also be set in other places, such as on panel frame 1.

[0052] In some exemplary embodiments, such as Figure 15 As shown, the output shaft of the stepper motor 31 passes through the stepper motor housing 33 and is interference-fitted with the oscillating component 32. The zero-point limiting structure includes a stop rib 331 located in the stepper motor housing 33. This design is simple in structure and reliable in use. Of course, the zero-point limiting structure is not limited to the structure of the stop rib 331; it can also be a stop bar, a stop block, a groove, or other structural forms.

[0053] In some embodiments, such as Figure 15As shown, the stepper motor housing 33 includes a housing 332 and a base 333. The stepper motor 31 is installed inside the housing 332, and the base 333 can be fixedly connected to the panel frame 1 by fasteners 244. The base 333 has a clearance notch 334, through which the swing member 32 passes and can swing within the clearance notch 334. A stop rib 331 is provided at least at one end of the clearance notch 334 to stop and engage with the swing member 32 when the panel assembly 2 is rotated to the closed position. Furthermore, the stop rib 331 can be arranged circumferentially along the clearance notch 334, which helps to improve the structural strength.

[0054] In some exemplary embodiments, the panel assembly 2 is detachably connected to the drive mechanism 3. This allows the panel assembly 2 to open to approximately 90° under gravity (e.g., ...). Figure 13 and Figure 14 As shown, this greatly facilitates the operator in cleaning and maintaining panel assembly 2, and also makes it easier for the operator to clean or maintain the return air vent area and the components inside the return air vent.

[0055] Furthermore, the panel assembly 2 is provided with a disassembly and assembly limiting structure. The disassembly and assembly limiting structure is configured to allow the panel assembly 2 to be connected to or disassembled from the drive mechanism 3 when it is in the closed position, and to restrict the panel assembly 2 from being connected to or disassembled from the drive mechanism 3 when it is in the open position.

[0056] In this way, the panel assembly 2 and the drive mechanism 3 can only be disassembled or connected when the panel assembly 2 is in the closed position. When the panel assembly 2 is in other positions, the panel assembly 2 and the drive mechanism 3 cannot be disassembled or connected. When the panel assembly 2 is in the closed position, the stepper motor 31 is also in the zero position. This helps to reduce the step difference caused by the disassembly and assembly process between the panel assembly 2 and the drive mechanism 3, and also facilitates the synchronization of multiple stepper motors 31 with fewer oversteps.

[0057] In some exemplary embodiments, panel assembly 2 includes a panel body and a decorative panel 24, such as Figure 3 , Figure 10 and Figure 12 As shown. The panel body is rotatably connected to the panel frame 1, and is configured to open and close the opening 11. The panel body is detachably connected to multiple drive mechanisms 3. The decorative panel 24 is located on the side of the panel body near the drive mechanism 3 and is fixedly connected to the panel body. The disassembly and assembly limiting structure includes a clearance groove 241 provided in the decorative panel 24, as shown. Figure 4 As shown.

[0058] With panel assembly 2 in the closed position, the connection between the panel body and drive mechanism 3 is aligned with the clearance groove 241 (e.g., ...). Figure 12 (as shown), so that the panel body can be connected to or detached from the drive mechanism 3.

[0059] In other words, only when panel component 2 is in the closed position, such as Figure 18 and Figure 19 As shown, only when the connection between the panel body and the drive mechanism 3 can it correspond to the clearance groove 241 of the decorative panel 24, and thus avoid interference from the decorative panel 24, allowing for free connection or disassembly. When the panel assembly 2 is in other positions, the panel body and the drive mechanism 3 cannot be connected or disassembled because they will be interfered with by the decorative panel 24.

[0060] In some exemplary embodiments, the panel body includes a panel 21 and a sliding limiting member 22, such as... Figure 3 As shown. Panel 21 is rotatably connected to panel frame 1, and is configured to open and close opening 11. Sliding limit member 22 is limited to panel 21 and can slide relative to panel 21 between locked and unlocked positions. Sliding limit member 22 has a sliding engagement part. The drive mechanism 3 also includes a swing member 32 connected to stepper motor 31, and the swing member 32 has a sliding part for engaging with the sliding engagement part. Opening 11 is a return air vent, and panel 21 is a return air panel. The sliding engagement part can be, but is not limited to, a sliding groove 2211, a slide rail, a sliding shaft 321, etc. The sliding part can be, but is not limited to, a sliding shaft 321, a slider, a sliding groove 2211, etc. The swing member 32 can be, but is not limited to, a swing rod.

[0061] Since the sliding limit member 22 is in the locked position, the sliding part can slide and rotate relative to the sliding mating part, so that the panel 21 can rotate between the open position and the closed position.

[0062] Based on the sliding limit member 22 being in the unlocked position, the sliding part and the sliding mating part are separated, so that the panel assembly 2 can be unlocked from the drive mechanism 3.

[0063] The panel 21 and the stepper motor 31 are connected by a sliding limit member 22 and a swing member 32. When the panel 21 does not require cleaning or maintenance, the sliding limit member 22 is in the locked position (e.g., Figures 8 to 11 As shown), this ensures effective engagement between the sliding mating part and the sliding part, so that the stepper motor 31 can drive the panel 21 to rotate between the open and closed positions. When the panel 21 needs cleaning or maintenance, the sliding limit member 22 can be slid to the unlocked position (as shown). Figure 12 As shown), at this time, the sliding engagement part disengages from the sliding part, thereby unlocking the panel assembly 2 from the drive mechanism 3. Therefore, the panel assembly 2 can be opened to approximately 90° under the action of gravity (as shown). Figure 13 and Figure 14 As shown, this greatly facilitates the operator in cleaning and maintaining the panel 21, and also makes it easier for the operator to clean or maintain the return air vent area and the components inside the return air vent.

[0064] In some exemplary embodiments, the sliding limiter 22 is configured to slide from a locked position to an unlocked position under external force, such as... Figure 12 As shown. Figure 12 The arrow in the diagram indicates the direction of the external force, which is also the direction in which the sliding limiter 22 slides from the locked position to the unlocked position.

[0065] Panel assembly 2 also includes elastic element 23, such as Figure 6 As shown. The elastic element 23 cooperates with the sliding limit element 22 and the panel 21, and is configured to use its reset elastic force to drive the sliding limit element 22 to slide from the unlocked position to the locked position.

[0066] In other words, when it is necessary to unlock the panel assembly 2 from the drive mechanism 3, a driving force can be applied to the sliding limit member 22. After the panel assembly 2 and the drive mechanism 3 are unlocked, the driving force on the sliding limit member 22 is removed, and the sliding limit member 22 will automatically return to the locked position.

[0067] Conversely, in the unlocked state, when it is necessary to connect the panel assembly 2 and the drive mechanism 3, first apply a driving force to the sliding limit member 22 to make the sliding limit member 22 slide to the position where the sliding mating part and the sliding part are directly opposite each other. Then remove the driving force on the sliding limit member 22, and the sliding limit member 22 will automatically return to the locked position. The sliding mating part and the sliding part cooperate to lock the panel assembly 2 and the drive mechanism 3.

[0068] The elastic element 23 reduces the difficulty of operation for the user and improves the user experience. Furthermore, unlocking the panel assembly 2 and the drive mechanism 3 requires applying external force to overcome the elasticity of the elastic element 23. Therefore, the elastic element 23 improves the stability of the sliding limit member 22 in the locked position, which in turn improves the reliability of the cooperation between the panel assembly 2 and the drive mechanism 3.

[0069] Of course, panel assembly 2 may not include elastic element 23, and the sliding limit member 22 can also slide from the unlocked position to the locked position by applying external force. Furthermore, the stability of sliding limit member 22 in the locked position can be ensured by using other limiting structures (such as pins, screws, etc. to lock and unlock the sliding part and the sliding mating part).

[0070] In some embodiments, the elastic element 23 and the limiting slider are an integral structure. Alternatively, the elastic element 23 and the limiting slider are separate assembly structures.

[0071] In another embodiment, the elastic element 23 and the panel 21 are an integral structure. Alternatively, the elastic element 23 and the panel 21 are separate assembly structures.

[0072] In some examples, panel 21 is provided with a limiting part 211, such as Figure 7 As shown. The elastic member 23 includes at least one elastic arm 231, one end of which is connected to the sliding limiting member 22, and the other end of which is limited to the limiting portion 211.

[0073] The structural form of the limiting part 211 is not limited. For example, the limiting part 211 can be a limiting post 2111, a limiting baffle 2113, a limiting block, a limiting plate 2112, or a combination thereof. Figure 9 As shown, a limiting plate 2112 can be set below the limiting post 2111, and a limiting baffle 2113 can be set on the side wall of the limiting post 2111. In this way, the limiting plate 2112 can be used to avoid friction between the elastic arm 231 and the panel 21, and can also play a better limiting role for the elastic arm 231.

[0074] The limiting engagement method between the elastic arm 231 and the limiting part 211 is also unrestricted. For example, the other end of the elastic arm 231 and the limiting part 211 can achieve limiting by abutting against each other, by plugging in, by hooking, or by fixed connection.

[0075] In other examples, the elastic element 23 is a spring, with one end of the spring limited to the limiting part 211 and the other end limited to the sliding limiting part 22. The limiting engagement method between the spring and the limiting part 211 and the sliding limiting part 22 is also not limited, and can be referred to the limiting method of the elastic arm 231 mentioned above, which will not be listed here one by one.

[0076] In some exemplary embodiments, the sliding limit member 22 includes a slide rail portion 221 and an operating portion 222. The slide rail portion 221 is provided with a sliding engagement portion. The operating portion 222 is connected to the slide rail portion 221 and is configured to drive the slide rail portion 221 to slide relative to the panel 21 under external force, so that the sliding portion disengages from the sliding engagement portion.

[0077] When it is necessary to unlock the drive mechanism 3 and the panel assembly 2, it can be operated through the operation unit 222. External force is applied to the operation unit 222, thereby causing the sliding limit member 22 to slide from the locked position to the unlocked position.

[0078] In one example, such as Figure 4 and Figure 7 As shown, the slide rail 221 is a roughly rectangular block structure with a sliding groove 2211. The operating part 222 can be a roughly rectangular plate structure.

[0079] The operating part 222 can be a pressing operating part 222, that is, a driving force is applied by pressing the operating part 222. The pressing direction is consistent with the direction in which the sliding limit member 22 slides from the locked position to the unlocked position, and the inlet and outlet of the sliding groove 2211 are oriented toward the operating part 222.

[0080] The operating part 222 can also be a pull-out operating part 222. That is, the driving force is applied by the pull-out operating part 222, and the pulling direction is consistent with the direction in which the sliding limit member 22 slides from the locked position to the unlocked position. Then the inlet and outlet of the sliding groove 2211 face away from the operating part 222.

[0081] In some exemplary embodiments, panel 21 is further provided with a guide and positioning part, such as Figure 7 As shown, the sliding limit member 22 also includes a guide positioning mating part 223. The guide positioning part cooperates with the guide positioning mating part 223 to guide the sliding limit member 22 to slide between the locked position and the unlocked position and to limit the sliding range of the sliding limit member 22.

[0082] This helps to improve the consistency of the sliding trajectory of the sliding limit component 22, and helps to avoid deviations in the sliding trajectory of the sliding limit component 22 or excessive sliding amplitude, which would affect the repeated disassembly and assembly of the panel assembly 2 and the drive mechanism 3.

[0083] In some exemplary embodiments, such as Figure 7 As shown, the guiding and positioning part includes a guiding and positioning post 212, and the guiding and positioning mating part 223 is provided with a guiding and positioning groove 2231. The guiding and positioning post 212 is inserted into the guiding and positioning groove 2231 and can slide relative to the guiding and positioning groove 2231. The guiding and positioning post 212 can be, but is not limited to, a cylinder or a frustum, and the guiding and positioning groove 2231 can be, but is not limited to, an oblong groove. When the guiding and positioning post 212 slides relative to the sliding limit member 22 to one end of the guiding and positioning groove 2231, the sliding limit member 22 is in the locked position; when the guiding and positioning post 212 slides relative to the sliding limit member 22 to the other end of the guiding and positioning groove 2231, the sliding limit member 22 is in the unlocked position.

[0084] Of course, the positions of the guide positioning post 212 and the guide positioning groove 2231 can also be interchanged, which can also guide the sliding limit member 22 during the sliding process between the locked position and the unlocked position.

[0085] In some exemplary embodiments, combined with Figures 8 to 11As shown, the sliding engagement part is configured as a sliding groove 2211 extending along the length direction of the slide rail part 221, and the sliding part is configured as a sliding shaft 321. The sliding shaft 321 is configured to insert into or disengage from the sliding groove 2211 along the width direction of the slide rail part 221. The sliding limit member 22 is configured to slide between a locked position and an unlocked position along the width direction of the slide rail part 221. The length direction of the slide rail part 221 may be perpendicular to the extension direction of the rotation axis of the panel 21, and the width direction of the slide rail part 221 may be consistent with the extension direction of the rotation axis of the panel 21.

[0086] The guide positioning mating part 223 and the operating part 222 are located on both sides of the slide rail part 221 in the width direction. The elastic element 23 of the panel assembly 2 includes two elastic arms 231, which are symmetrically arranged on both sides of the guide positioning mating part 223 and connected to both ends of the guide positioning mating part 223 along the length direction of the slide rail part 221.

[0087] The guide positioning fitting part 223 can be roughly plate-shaped. Along the length of the slide rail part 221, the length of the guide positioning fitting part 223 can be greater than the operating part 222 and less than the slide rail part 221. A guide positioning groove 2231 is provided in the middle of the slide rail part 221 along its length. Both ends of the guide positioning fitting part 223 are connected to two elastic arms 231, as shown below. Figure 7 As shown, the other ends of the two elastic arms 231 can abut against the limiting part 211 (such as the limiting post 2111) on the panel 21 respectively. The part (root) where the elastic arm 231 connects to the guide positioning mating part 223 can be appropriately thickened to improve the root strength and reduce the risk of breakage.

[0088] In some exemplary embodiments, panel 21 is provided with limiting ribs 215, such as... Figure 6 and Figure 7 As shown. The limiting rib 215 is located on the side of the slide rail 221 away from the elastic arm 231 and abuts against the slide rail 221, so that the elastic arm 231 is in an elastic deformation state when the sliding limiting member 22 is in the locked position, thereby preventing the sliding part from disengaging from the sliding mating part. There can be two limiting ribs 215, and the two limiting ribs 215 can be symmetrically arranged on both sides of the operating part 222.

[0089] Thus, when the sliding limit member 22 is in the locked position, the elastic arm 231 is in a relatively weak elastic deformation state; when the sliding limit member 22 is in the unlocked position, the elastic arm 231 is in a relatively strong elastic deformation state. This helps to increase the driving force required to unlock the panel assembly 2 and the drive mechanism 3, thereby helping to prevent the panel assembly 2 and the drive mechanism 3 from being accidentally unlocked.

[0090] In some embodiments, the elastic arm 231 and the sliding limit member 22 are an integral structure, such as Figure 7 As shown, the integrated structure is a mirror-symmetrical structure, with the symmetrical plane perpendicularly bisecting the operating part 222, the slide rail part 221, and the guide positioning mating part 223.

[0091] In some exemplary embodiments, one end of the panel 21 is provided with a limiting groove 213, such as... Figure 7 As shown. The operating part 222 has a protrusion 2221 at the end away from the slide rail part 221, and the operating part 222 passes through the limiting groove 213, as shown. Figure 7 As shown.

[0092] With the sliding limiter 22 in the locked position, the protrusion 2221 protrudes from one end of the limit groove 213 and the panel 21. This facilitates user identification of the operation.

[0093] The operation unit 222 can be configured as a pressing operation unit 222, which can slide the sliding limit member 22 to the unlock position under the pressing driving force, and cause the protrusion 2221 to at least partially retract into the limiting groove 213; or, the operation unit 222 can be configured as a pulling operation unit 222, which can slide the sliding limit member 22 to the unlock position under the pulling action, and increase the length of the protrusion 2221 protruding from the limiting groove 213.

[0094] In some exemplary embodiments, the decorative panel 24 and the panel 21 enclose a receiving groove, and a portion of the sliding limiter 22 is located within the receiving groove, such as... Figure 4 and Figure 11 As shown.

[0095] Based on panel assembly 2 being in the closed position and sliding mating part sliding to the unlocked position: the sliding part corresponds to the clearance groove 241 (e.g.) Figure 12 and Figure 19 (as shown), and can pass through the clearance slot 241 so that the swing member 32 can detach from or connect to the panel assembly 2.

[0096] The decorative panel 24 serves two main purposes. First, it provides aesthetic appeal by concealing the sliding limiter 22 and other structures (such as the elastic arm 231, the guide and positioning mating part 223, the limiting part 211 of the panel 21, and the guide and positioning part) when the return air vent of the panel 21 is open, thus enhancing the air conditioner's appearance. Second, the decorative panel 24 also limits the sliding limiter 22, preventing it from tilting up or detaching from the panel 21, thereby improving its reliability. Furthermore, the decorative panel 24 restricts the assembly and disassembly positions of the swing member 32 and the panel body, ensuring that the swing member 32 can only be disassembled or reassembled when the panel assembly 2 is in the closed position, which helps reduce the step difference between different timing motors 31.

[0097] Figures 16 to 19 The diagram illustrates the connection process between the panel body and the swing component 32. Figure 16 and Figure 17 In the middle, the stepper motor 31 is at the zero position, the sliding limit piece 22 is pressed, and the control panel component 2 is adjusted accordingly. Figure 17 The arrow in the diagram rotates counterclockwise towards the closed position, causing the sliding shaft 321 of the swing member 32 to approach the clearance groove 241 of the decorative panel 24. Figure 18 and Figure 19 In the middle, the panel assembly 2 is in the closed position, the sliding shaft 321 of the swing member 32 passes through the relief groove 241, the sliding limit member 22 is released, and the sliding shaft 321 of the swing member 32 can be embedded in the sliding groove 2211 of the sliding limit member 22, thus completing the connection and assembly process between the drive mechanism 3 and the panel assembly 2.

[0098] Conversely, during disassembly, in Figure 18 and Figure 19 In the state shown, panel assembly 2 is in the closed position. Press the sliding limit piece 22 and control panel assembly 2 to rotate clockwise downwards. The sliding shaft 321 of the swing piece 32 can pass through the clearance groove 241 and disengage from panel assembly 2, completing the disassembly and separation process between drive mechanism 3 and panel assembly 2. Then release the sliding limit piece 22, and panel assembly 2 can rotate downwards to 90°.

[0099] In some embodiments, the area of ​​the decorative panel 24 is smaller than the area of ​​the panel 21, and the area of ​​the decorative panel 24 may be smaller than the area of ​​the return air vent, so that the decorative panel 24 can be at least partially embedded in the return air vent when the panel 21 is in the closed position.

[0100] In one embodiment, the decorative panel 24 is provided with a connection hole 243, such as Figure 12 As shown, the connecting hole 243 is correspondingly set with the limiting post 2111 on the panel 21, and the fastener 244 passes through the connecting hole 243 and is fixedly connected to the limiting post 2111, as shown. Figure 4As shown, this achieves a fixed connection between the decorative panel 24 and the panel 21.

[0101] In some exemplary embodiments, the decorative panel 24 is also provided with anti-detachment ribs 242, such as... Figure 4 , Figure 11 and Figure 12 As shown. The anti-detachment rib 242 is located on the side of the slide rail 221 near the swing member 32, and the swing member 32 is located between the anti-detachment rib 242 and the slide rail 221, and is configured to restrict the swing member 32 from moving away from the slide rail 221.

[0102] The anti-detachment rib 242 can be roughly shaped as a rectangular structure with one end open 11, such as... Figure 4 , Figure 11 and Figure 12 As shown, the opening 11 faces the slide rail 221. The anti-detachment rib 242 can prevent the swing member 32 from moving in the sliding direction of the sliding limit member 22 and detaching from the sliding limit member 22, thereby improving the positional stability and reliability of the swing member 32.

[0103] In some exemplary embodiments, the anti-detachment rib 242 is provided with a socket 2421, such as Figure 11 and Figure 12 As shown, the operating part 222 passes through the insertion hole 2421. This allows for better limiting of the sliding limit member 22, which helps improve the stability and reliability of the sliding limit member 22.

[0104] In some exemplary embodiments, panel 21 is detachably connected to panel frame 1.

[0105] In this way, once the panel assembly 2 is unlocked from the drive mechanism 3, the entire panel assembly 2 can be removed from the panel frame 1 for easy cleaning and other operations.

[0106] In some exemplary embodiments, such as Figure 3 , Figure 5 and Figure 14 As shown, one of the panel 21 and the panel frame 1 is provided with a bushing 214, and the other is provided with a rotating shaft 12. The panel 21 is configured to: be movable relative to the panel frame 1 in a first direction, so that the rotating shaft 12 is inserted into the bushing 214 to assemble the panel 21 onto the panel frame 1; and be movable relative to the panel frame 1 in a second direction opposite to the first direction, so that the rotating shaft 12 is disengaged from the bushing 214 to detach the panel 21 from the panel frame 1. Figure 13 The arrow in the image indicates the second direction.

[0107] When it is necessary to disassemble panel assembly 2, a sliding driving force can be applied to the sliding limit member 22 to slide it from the locked position to the unlocked position. The external force can then be removed, causing the sliding post of the swing member 32 to disengage from the sliding groove 2211 of the sliding limit member 22 and exit through the clearance groove 241 of the decorative panel 24, thus unlocking the drive mechanism 3 from the panel assembly 2. Then, panel assembly 2 can be moved along the second direction, such as... Figure 13 As indicated by the arrow in the image, the panel assembly 2 can be removed by disengaging the rotating shaft 12 from the bushing 214.

[0108] Conversely, during installation, the panel assembly 2 can be moved along the first direction first, so that the rotating shaft 12 is inserted into the bushing 214; then a sliding driving force is applied to the sliding limit member 22, so that the sliding limit member 22 slides from the locked position to the unlocked position, and the panel assembly 2 is rotated until the sliding shaft 321 of the swing member 32 passes through the clearance groove 241 of the decorative plate 24 and reaches the groove of the sliding groove 2211. Then the external force is removed, and the sliding limit member 22 can automatically reset, so that the sliding shaft 321 is inserted into the sliding groove 2211, thereby realizing the assembly between the panel assembly 2 and the drive mechanism 3.

[0109] Of course, the detachable connection between panel frame 1 and panel 21 is not limited to this. For example, both panel frame 1 and panel 21 can be equipped with bushings 214. The assembly between panel frame 1 and panel 21 is achieved by inserting a pivot 12, which is independent of panel frame 1 and panel 21, into the bushings 214 of panel frame 1 and panel 21, and the panel assembly 2 is removed from panel frame 1 by pulling out the pivot 12.

[0110] In some exemplary embodiments, the number of rotating shafts 12 and bushings 214 are both multiple, spaced apart along the axial direction of the rotating shaft 12. Multiple rotating shafts 12 are correspondingly arranged with multiple bushings 214, and the distance between adjacent bushings 214 is greater than the length of the rotating shaft 12. Figure 14 As shown.

[0111] This reduces the range of movement of panel assembly 2 when it is disassembled or assembled, which helps to reduce the difficulty of operation for the operator.

[0112] In some exemplary embodiments, the panel frame 1 is further provided with an anti-detachment engagement member, which has a locked state and an unlocked state.

[0113] When the anti-detachment engagement is in the locked state, it restricts the panel 21 from moving in the second direction to prevent the shaft 12 from disengaging from the bushing 214. When the anti-detachment engagement is in the unlocked state, the limiting member releases the restriction on the panel 21, allowing the panel 21 to move in the second direction to disengage the shaft 12 from the bushing 214.

[0114] The anti-detachment fitting is designed to prevent the pivot 12 from disengaging from the bushing 214 under natural conditions, thus preventing the panel assembly 2 from falling off. The anti-detachment fitting can be, but is not limited to, a snap-fit, pry-fit, or locking mechanism.

[0115] In one embodiment, one end of the panel 21 is provided with a plurality of bushings 214, such as Figure 3 and Figure 5 As shown, multiple bushings 214 are integrally formed with the panel 21. The panel 21 may also be provided with multiple reinforcing ribs to strengthen the bushings 214. Multiple rotating shafts 12 and anti-detachment limiting components 13 are integrally formed with the panel frame 1. The anti-detachment limiting component 13 is a snap-fit, such as... Figure 14 As shown, when the anti-disengagement engagement is in the locked state, the anti-disengagement engagement is located on the other side of the insertion port of the bushing 214 to restrict the bushing 214 from moving in the direction of disengagement from the rotating shaft 12 (i.e., the second direction). By prying the buckle upward, the buckle can be deviated from the movement direction of the bushing 214 to the unlocked state, and the panel assembly 2 can be moved along the second direction and removed.

[0116] Conversely, during installation, the buckles can be bent until the rotating shaft 12 is inserted into the bushing 214 to assemble the panel assembly 2 with the panel frame 1 bracket.

[0117] The number of anti-detachment limiting components 13 can be set to one or multiple. Setting one reduces the difficulty of operation for the operator and improves the ease of disassembly and assembly of the panel assembly 2.

[0118] This application also provides an air conditioner, including a panel device and a control device as described in any of the above embodiments. The control device is electrically connected to a plurality of stepper motors 31 and is configured to control the plurality of stepper motors 31.

[0119] The air conditioner provided in this application embodiment includes the panel device of any of the above embodiments, and therefore has the above-mentioned beneficial effects, which will not be repeated here.

[0120] Among them, the air conditioner can be, but is not limited to, a built-in air conditioner, and the built-in air conditioner can be, but is not limited to, a kitchen air conditioner.

[0121] In some exemplary embodiments, the rotation angle of the stepper motor 31 is denoted as 'a', based on the rotation of the panel assembly 2 from the open position to the closed position; Δa (e.g., ...) Figure 20 (As shown) is the compensation angle value. △a can be in the range of 3° to 5°.

[0122] The control device is configured as follows:

[0123] Since the air conditioner is in the on state, upon receiving the shutdown command, it sends a closing angle of a+△a to all stepper motors 31; after all stepper motors 31 have completed the execution, it sets the current position of all stepper motors 31 to the zero position.

[0124] Since the air conditioner is in the off state, upon receiving the power-on command, a command with a closing angle of △a is sent to all stepper motors 31; after all stepper motors 31 have completed the execution, the current position of all stepper motors 31 is set to the zero position; and a command with an opening angle of a is sent to all stepper motors 31.

[0125] When the air conditioner is on, panel assembly 2 is in the open position. When a shutdown command is received, the control device theoretically needs to send a closing angle of 'a' to all stepper motors 31. However, considering the potential for asynchrony among multiple stepper motors 31, a closing angle of 'a+Δa' is sent to all stepper motors 31. The extra 'Δa' ensures that all stepper motors 31 can reset and rotate to a position where they cannot continue rotating (due to the limitation of the zero-point limit structure), thus guaranteeing that all stepper motors 31 can reset and rotate to the zero-point position. When all stepper motors 31 have completed their operations, their current positions are set to the zero-point position. In this way, after each shutdown, all stepper motors 31 are in the zero-point position, achieving synchronization without affecting the lifespan of the stepper motors 31.

[0126] When the air conditioner is off, panel assembly 2 is in the closed position. When a power-on command is received, the control device theoretically needs to send an opening angle of 'a' to all stepper motors 31. However, considering the potential for asynchrony among the multiple stepper motors 31, a closing angle of 'Δa' is sent to all stepper motors 31 first. By first resetting and rotating 'Δa', it ensures that all stepper motors 31 can reset and rotate to a position where they cannot continue rotating (due to the limitation of the zero-point limit structure), thus ensuring that all stepper motors 31 can reset and rotate to the zero-point position. When all stepper motors 31 have completed their execution, their current positions are set to the zero-point position. Then, the opening angle command of 'a' is sent to all stepper motors 31. In this way, each time the air conditioner is powered on, all stepper motors 31 first achieve synchronization before starting operation, which is beneficial for the synchronized rotation of multiple stepper motors 31.

[0127] In this way, by compensating for the false position difference through the operation control method, the air conditioner can achieve synchronization every time it is turned on or off. This helps to greatly reduce the step difference between different stepper motors 31, and allows the number of oversteps of each stepper motor 31 to be controlled within a very small range. This helps to reduce the stall time of the stepper motor 31 and improve its service life.

[0128] In some exemplary embodiments, the control device is further configured to: send a command with a closing angle of a+a to all stepper motors 31 upon first power-on after the air conditioner has been powered off; and set the current position of all stepper motors 31 to the zero position upon completion of the command by all stepper motors 31.

[0129] After a power outage, the air conditioner may be under maintenance, and the panel assembly 2 may be manually bent to a relatively large angle. Therefore, when power is restored for the first time after a power outage, the closing angle range of the closing angle command sent to all stepper motors 31 is relatively large (a+a) to ensure that all stepper motors 31 can reset and rotate to the zero position. When all stepper motors 31 have completed their execution, the current position of all stepper motors 31 is set to the zero position. Because the process of resetting the zero position when power is restored for the first time after a power outage involves a large number of steps, it can lead to a prolonged stall time for the stepper motors 31. However, since the air conditioner can achieve synchronization every time it is turned on and off in this embodiment, it is not necessary to perform a power outage and power-on process every time the zero position is reset. Therefore, the zero position reset process when power is restored for the first time after a power outage is rarely used, and thus the impact on the lifespan of the stepper motors 31 is minimal.

[0130] This application embodiment also provides a control method for the air conditioner in the above embodiments, the control method comprising:

[0131] Based on the air conditioner being in the on state, upon receiving a shutdown command, a command with a closing angle of a + Δa is sent to all stepper motors 31; based on the completion of the execution by all stepper motors 31, the current position of all stepper motors 31 is set to the zero position; and / or

[0132] Since the air conditioner is in the off state, upon receiving the power-on command, a command with a closing angle of △a is sent to all stepper motors 31; since all stepper motors 31 have completed the execution, the current position of all stepper motors 31 is set to the zero position; and a command with an opening angle of a is sent to all stepper motors 31.

[0133] In some exemplary embodiments, the control method further includes:

[0134] Based on the first power-on after the air conditioner is powered off, a command with a closing angle of a+a is sent to all stepper motors 31; based on the completion of all stepper motors 31, the current position of all stepper motors 31 is set to the zero position.
