Description

Technical Field

[0001] The present application relates to but is not limited to the field of air-conditioning technology, and specifically refers to a panel device and an air-conditioner. Background Art

[0002] In the related art, some openings of the panel frame are designed to be larger, resulting in a larger size and heavier weight of the corresponding panel assembly. In this case, a single stepper motor is generally unable to drive the panel assembly to rotate, and two or more stepper motors are required to drive the panel assembly to rotate. However, after running for a period of time, multiple stepper motors will have a synchronization problem, resulting in the panel device running unsmoothly and producing abnormal noise, and even causing the panel to distort, resulting in the panel assembly being unable to completely close the opening and other problems. Utility Model Content

[0003] The technical problem to be solved by the present application is to provide a panel device, which facilitates synchronization between multiple stepper motors by setting a zero point limit structure, thereby helping to avoid problems such as abnormal noise or panel distortion caused by the unsmooth operation of the panel device.

[0004] To this end, an embodiment of the present application provides a panel device, comprising: a panel frame, the panel frame being provided with an opening; a panel assembly, rotatably connected to the panel frame and configured to be able to open and close the opening; and a plurality of driving mechanisms, connected to the panel assembly, configured to drive the panel assembly to reciprocate between an open position for opening the opening and a closed position for closing the opening; the driving mechanism comprising a stepper motor and a zero point limit structure, the zero point limit structure being configured to limit the corresponding stepper motor from continuing to rotate when the corresponding stepper motor is reset and rotated to the zero point position.

[0005] An embodiment of the present application further provides an air conditioner, comprising a panel device and a control device as described in any one of the above embodiments, wherein the control device is electrically connected to the plurality of stepper motors and is configured to control the plurality of stepper motors.

[0006] The panel device and air conditioner provided in the embodiments of the present application, by setting a zero-point limit structure, are conducive to reducing the step difference between asynchronous stepper motors, so that the stepper motor can achieve synchronization between multiple stepper motors through a relatively small number of steps, thereby solving the problem of asynchrony between multiple stepper motors and does not affect the service life of the stepper motor.

[0007] Specifically, since the zero-point limiting structure can limit the stepper motor from continuing to rotate when the stepper motor is reset to the zero position, therefore, as long as each stepper motor is guaranteed to be reset and rotated to a position where it cannot continue to rotate (because it is limited by the zero-point limiting structure) after each use, it can be guaranteed that each stepper motor is reset to the zero position each time, thereby reducing the probability of asynchronous problems, and it is also beneficial to reduce the step difference between asynchronous stepper motors. Similarly, as long as each stepper motor is guaranteed to be reset and rotated to a position where it cannot continue to rotate (because it is limited by the zero-point limiting structure) before each use, it can be guaranteed that each stepper motor is reset to the zero position, and then the number of steps is set from this position, which is also beneficial to reduce the probability of asynchronous problems, and it is also beneficial 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 limiting structure, the step difference can be limited to a very small range, and the synchronization between multiple stepper motors can be easily achieved through a small number of overstepping steps. Due to the small number of overstepping steps, the problem of motor stalling time being too long will not be caused, and thus the service life of the stepper motor will not be affected.

[0032] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0033] The embodiment of the present application provides a panel device and an air conditioner. The panel device can be used for an embedded air conditioner to solve the problem that the return air vent is prone to oil and steam 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. In order to ensure the air intake, the return air vent will be designed to be relatively large, so the return air panel assembly will also be relatively large and heavy, requiring multiple stepper motors 31 to drive together, but this will bring about the problem of multiple stepper motors 31 being out of sync. The panel device provided in the embodiment of the present application can better solve this problem.

[0034] Of course, the panel device can also be used in other scenarios. For example, the panel assembly 2 can also be an air outlet panel assembly, and the opening 11 is an air outlet; or, the panel assembly 2 is an inspection panel, and the opening 11 is an inspection port; or, the opening 11 is an opening 11 for other purposes, and the panel assembly 2 is a panel assembly 2 for other purposes. The equipment including the panel device is not limited to embedded air conditioners, but can also be non-embedded air conditioners, or other equipment, such as air purifiers.

[0035] Embedded air conditioners can be used in kitchens, but they can also be used in other places. Embedded air conditioners can be all-in-one units or indoor units of split air conditioners. Embedded air conditioners can be installed in the ceiling (such as in a suspended ceiling) or in the wall. The following is an example of a panel device used for an air conditioner, and the air conditioner is an embedded kitchen air conditioner, and is installed in a suspended ceiling.

[0036] like Figure 1 , Figure 2 , Fig.13 and Fig.14As shown, an embodiment of the present application 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 is provided with an opening 11. The opening 11 is a return air port.

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

[0039] A plurality of driving mechanisms 3 are connected to the panel assembly 2, and are configured to drive the panel assembly 2 to reciprocate between an open position for opening the opening 11 and a closed position for closing the opening 11. Each driving mechanism 3 includes a stepping motor 31 and a zero-point limiting structure, and the zero-point limiting structure is configured to limit the corresponding stepping motor 31 from continuing to rotate when the corresponding stepping motor 31 is reset and rotated to the zero-point position. The zero-point limiting structure and the corresponding stepping motor 31 refer to the zero-point limiting structure and the stepping motor 31 belonging to the same driving mechanism 3.

[0040] A plurality of driving mechanisms 3 may be arranged at intervals along the extension direction of the rotation axis of the panel assembly 2 to jointly provide driving force to the panel assembly 2. For example, the number of driving mechanisms 3 may be two, and the two driving mechanisms 3 may be respectively connected to the two end regions (regions close to the edge, not necessarily the two ends) of the panel assembly 2. The number of driving mechanisms 3 may also be three, of which two driving mechanisms 3 may be respectively connected to the two end regions of the panel assembly 2, and another driving mechanism 3 may be connected to the middle of the panel assembly 2.

[0041] The panel device provided in the embodiment of the present application can open or close the opening 11 (i.e., the return air vent) on the panel frame 1 through the panel assembly 2. In this way, when the air conditioner needs to be turned on, the multiple driving mechanisms 3 can drive the panel assembly 2 to open the opening 11, such as Figure 1 , Figure 8 and Fig. 9 As shown, the indoor air flow can enter the air conditioner through the return air port to ensure the normal use of the air conditioner. When the air conditioner does not need to be turned on, the multiple driving mechanisms 3 can drive the panel assembly 2 to close the opening 11 (such as Fig.10 and Fig.11 As shown in the figure, grease, steam, etc. can only stay outside the air conditioner, preventing grease, steam, etc. in the kitchen from entering the air conditioner through the return air port, which is beneficial to increasing the service life of the grease filter and evaporator, and extending the cleaning cycle of the air conditioner, thereby improving user experience and the reliability of the air conditioner.

[0042] Furthermore, by reasonably controlling the opening angle of the panel assembly 2 when the air conditioner is in use (for example, less than 90°), Figure 1 and Figure 2As shown, the oil stains entering the interior of the equipment can be effectively reduced while ensuring the return air volume of the air conditioner, because the panel assembly 2 itself can intercept a part of the oil stains, so that the oil stains are deposited on the panel assembly 2.

[0043] The problem of multiple stepper motors 31 being out of sync can be solved by the first power-on over-step reset design, that is: when the power is first turned on, multiple stepper motors 31 are closed and over-stepped at the same time, and the step range of the received rotation step command exceeds the actual running step range of the stepper motor 31. After the stepper motor 31 is executed, the position at this time is determined as the zero position, and then each stepper motor 31 can be operated in the predetermined step range. However, this solution has the following problems: each time the zero position is reset, the power needs to be turned off, and then the power is turned on again, so as to reset the zero position through the first power-on over-step reset design, and the power-off and power-on operations need to be performed by the user, which is relatively complicated; and the zero position is reset by the first power-on over-step reset design, because the number of over-step steps is large (to ensure that each stepper motor 31 can be reset to the zero position), resulting in a long motor stall time, and long-term use of this reset method will reduce the service life of the stepper motor 31.

[0044] The panel device provided in the embodiment of the present application, by setting a zero point limit structure, is conducive to reducing the step difference between asynchronous stepper motors 31, so that the stepper motor 31 can achieve synchronization between multiple stepper motors 31 through a relatively small number of overstepping steps, thereby solving the problem of asynchrony between multiple stepper motors 31 and does not affect the service life of the stepper motor 31.

[0045] Specifically, since the zero-point limiting structure can limit the stepper motor 31 from continuing to rotate when the stepper motor 31 is reset to the zero position, as long as each stepper motor 31 is reset and rotated to a position where it cannot continue to rotate (because it is limited by the zero-point limiting structure) after each use, it can be ensured that each stepper motor 31 is reset to the zero position each time, thereby reducing the probability of asynchronous problems, and is also conducive to reducing the step difference between asynchronous stepper motors 31. Similarly, as long as each stepper motor 31 is reset and rotated to a position where it cannot continue to rotate (because it is limited by the zero-point limiting structure) before each use, it can be ensured that each stepper motor 31 is reset to the zero position, and then the set number of steps is rotated from this position, which is also conducive to reducing the probability of asynchronous problems, and is also conducive to reducing 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 the synchronization between multiple stepper motors 31 can be easily achieved through a small number of overstepping steps. Since the number of overstepping steps is small, the motor will not be blocked for a long time, and thus the service life of the stepping motor 31 will not be affected.

[0046] In some exemplary embodiments, the driving mechanism 3 further includes a swinging member 32 connected to the stepping motor 31 , and the swinging member 32 is connected to the panel assembly 2 .

[0047] The zero-point limit structure is configured to cooperate with the swing member 32 when the driving mechanism 3 drives the panel assembly 2 to rotate to the closed position. Fig.15 , Fig.18 and Fig.19 As shown, the stepping motor 31 is restricted from continuing to rotate, so that the stepping motor 31 is reset and rotated to the zero position.

[0048] In other words, the zero point limit structure does not directly limit the stepper motor 31 from continuing to rotate, but indirectly limits the stepper motor 31 from continuing to rotate by limiting the swing member 32 that is transmission-connected to the stepper motor 31. This facilitates reasonable setting of the structural form and position of the zero point limit structure.

[0049] Of course, the zero-point limiting structure may also directly cooperate with the stepper motor 31 , for example, when the stepper motor 31 is reset and rotated to the zero-point position, it may stop and cooperate 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 driving mechanism 3 further includes a stepping motor box 33 disposed on the panel frame 1, such as Fig.15 and Fig. 20 The stepper motor 31 is installed in the stepper motor box 33 , and the zero point limit structure is arranged in the stepper motor box 33 .

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

[0052] In some exemplary embodiments, Fig.15 As shown, the output shaft of the stepper motor 31 is inserted into the stepper motor box 33 and is interference fit with the swing member 32, and the zero point limit structure includes a stop rib 331 provided in the stepper motor box 33. This solution has a simple structure and is reliable to use. Of course, the zero point limit structure is not limited to the structural form of the stop rib 331, for example, it can also be a gear lever, a block, a groove, etc.

[0053] In some embodiments, Fig.15As shown, the stepper motor box 33 includes a box body 332 and a base 333. The stepper motor 31 is installed in the box body 332. The base 333 can be fixedly connected to the panel frame 1 through a fastener 244. The base 333 is provided with an escape notch 334. The swing member 32 is inserted through the escape notch 334 and can swing in the escape notch 334. The stop rib 331 is provided at least at one end of the escape notch 334 to stop and cooperate with the swing member 32 when the panel assembly 2 rotates to the closed position. Furthermore, the stop rib 331 can be arranged along the circumference of the escape notch 334, which is conducive to improving the structural strength.

[0054] In some exemplary embodiments, the panel assembly 2 is detachably connected to the drive mechanism 3. In this way, the panel assembly 2 can be opened to about 90° (e.g., Fig.13 and Fig.14 As shown), it is greatly convenient for the operator to clean and repair the panel assembly 2, and it is also convenient for the operator to clean or repair the return air outlet area and the components inside the return air outlet.

[0055] Furthermore, the panel assembly 2 is provided with a disassembly and assembly limiting structure, which is configured to enable the panel assembly 2 to be connected to or disassembled from the driving mechanism 3 when in a closed position, and to limit the panel assembly 2 from being connected to or disassembled from the driving mechanism 3 when in a non-closed position.

[0056] In this way, only when the panel assembly 2 is in the closed position, the panel assembly 2 and the drive mechanism 3 can realize the disassembly process or the connection process. When the panel assembly 2 is in other positions, the panel assembly 2 and the drive mechanism 3 cannot realize disassembly or connection. When the panel assembly 2 is in the closed position, the stepper motor 31 is also in the zero position. This is conducive to reducing the step difference caused by the disassembly and assembly process between the panel assembly 2 and the drive mechanism 3, and is also convenient for easily realizing the synchronization between multiple stepper motors 31 through a small number of overstepping steps.

[0057] In some exemplary embodiments, the panel assembly 2 includes a panel body and a decorative panel 24, such as Figure 3 , Fig.10 and Fig.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 the plurality of drive mechanisms 3. The decorative plate 24 is located on the side of the panel body close to the drive mechanism 3 and is fixedly connected to the panel body. The disassembly and assembly limiting structure includes an avoidance groove 241 provided on the decorative plate 24. Figure 4 shown.

[0058] Based on the panel assembly 2 being in the closed position, the connection portion between the panel body and the driving mechanism 3 is arranged corresponding to the avoidance groove 241 (such as Fig.12 As shown), so that the panel body can be connected to or removed from the driving mechanism 3.

[0059] In other words, only when the panel assembly 2 is in the closed position, Fig.18 and Fig.19 As shown, the connection part between the panel body and the driving mechanism 3 can correspond to the avoidance groove 241 of the decorative plate 24, and will not be interfered by the decorative plate 24, and can be freely connected or disassembled. When the panel assembly 2 is in other positions, the panel body and the driving mechanism 3 cannot be connected or disassembled because they will be interfered by the decorative plate 24.

[0060] In some exemplary embodiments, the panel body includes a panel 21 and a sliding stopper 22. Figure 3 As shown. The panel 21 is rotatably connected to the panel frame 1 and is configured to open and close the opening 11. The sliding limiter 22 is limited to the panel 21 and can slide between a locked position and an unlocked position relative to the panel 21. The sliding limiter 22 is provided with a sliding fitting portion. The driving mechanism 3 also includes a swinging member 32 connected to the stepping motor 31, and the swinging member 32 is provided with a sliding portion for matching with the sliding fitting portion. The opening 11 is a return air port, and the panel 21 is a return air panel. The sliding fitting portion may be, but not limited to, a sliding groove 2211, a sliding rail, a sliding shaft 321 and other structural forms. The sliding portion may be, but not limited to, a sliding shaft 321, a sliding block, a sliding groove 2211 and other structural forms. The swinging member 32 may be, but not limited to, a swing rod.

[0061] Based on the sliding limiter 22 being located at the locking position, the sliding portion can slide and rotate relative to the sliding matching portion, so that the panel 21 can rotate between the open position and the closed position.

[0062] Based on the sliding limiter 22 being located at the unlocking position, the sliding portion is separated from the sliding fitting portion, so that the panel assembly 2 can be unlocked from the driving mechanism 3 .

[0063] The panel 21 and the stepper motor 31 are matched with each other through the sliding stopper 22 and the swing member 32. When the panel 21 does not need to be cleaned and repaired, the sliding stopper 22 is in a locked position (such as Figures 8 to 11 As shown in FIG. 1 ), the sliding fitting part and the sliding part are effectively matched to ensure that the stepper motor 31 can drive the panel 21 to rotate between the open position and the closed position. When the panel 21 needs to be cleaned and repaired, the sliding limiter 22 can be slid to the unlocking position (as shown in FIG. Fig.12 As shown), the sliding fitting portion is disengaged from the sliding portion, so that the panel assembly 2 is unlocked from the driving mechanism 3, so that the panel assembly 2 can be opened to about 90° (as shown) under the action of gravity. Fig.13 and Fig.14 As shown), it is greatly convenient for the operator to clean and repair the panel 21, and it is also convenient for the operator to clean or repair the return air outlet area and the components inside the return air outlet.

[0064] In some exemplary embodiments, the sliding stopper 22 is configured to slide from the locking position to the unlocking position under the driving of an external force, such as Fig.12 shown. Fig.12 The arrow in illustratively shows the direction of the external force, which is also the direction in which the sliding limit member 22 slides from the locking position to the unlocking position.

[0065] The panel assembly 2 further includes an elastic member 23, such as Figure 6 The elastic member 23 cooperates with the sliding limit member 22 and the panel 21, and is configured to utilize its restoring elastic force to drive the sliding limit member 22 to slide from the unlocking position to the locking position.

[0066] In other words, when the panel assembly 2 and the driving mechanism 3 need to be unlocked, a driving force is applied to the sliding limiter 22. When the panel assembly 2 and the driving mechanism 3 are unlocked, the driving force on the sliding limiter 22 is removed, and the sliding limiter 22 can automatically return to the locked position.

[0067] On the contrary, in the unlocked state, when it is necessary to connect the panel assembly 2 with the driving mechanism 3, firstly apply a driving force to the sliding limit member 22 to make the sliding limit member 22 slide to a position where the sliding matching part and the sliding part are opposite to each other, and then remove the driving force on the sliding limit member 22, the sliding limit member 22 can automatically reset to the locked position, and the sliding matching part cooperates with the sliding part to realize the locking of the panel assembly 2 and the driving mechanism 3.

[0068] The provision of the elastic member 23 can reduce the difficulty of the operator's operation, which is conducive to improving the user's experience. In addition, the unlocking of the panel assembly 2 and the drive mechanism 3 requires the application of an external force to overcome the elastic force of the elastic member 23, so the elastic member 23 improves the stability of the sliding limiter 22 in the locked position, which is conducive to improving the matching reliability of the panel assembly 2 and the drive mechanism 3.

[0069] Of course, the panel assembly 2 may not include the elastic member 23, and the sliding of the sliding limiter 22 from the unlocked position to the locked position may also be achieved by applying an external force. Furthermore, other limiting structures (such as latches, screws, etc. to achieve locking and unlocking of the sliding part and the sliding matching part) are used to ensure the stability of the sliding limiter 22 in the locked position.

[0070] In some embodiments, the elastic member 23 and the limiting sliding member are an integrated structure. Alternatively, the elastic member 23 and the limiting sliding member are a split assembly structure.

[0071] In another embodiment, the elastic member 23 and the panel 21 are an integrated structure. Alternatively, the elastic member 23 and the panel 21 are a split assembly structure.

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

[0073] The structural form of the limiting part 211 is not limited. For example, the limiting part 211 can be a limiting column 2111, a limiting rib 2113, a limiting block, a limiting plate 2112, or a combination thereof. Fig. 9 As shown, a limiting plate 2112 can be set under the limiting column 2111, and a limiting rib 2113 can be set on the side wall of the limiting column 2111, so that the limiting plate 2112 can be used to avoid friction between the elastic arm 231 and the plate surface of the panel 21, and can also play a better limiting role for the elastic arm 231.

[0074] The limiting cooperation mode between the elastic arm 231 and the limiting part 211 is also not limited. For example, the other end of the elastic arm 231 and the limiting part 211 can achieve limiting by abutting against each other, or by plugging, or by hooking, or by fixed connection.

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

[0076] In some exemplary embodiments, the sliding stopper 22 includes: a slide rail portion 221 and an operating portion 222. The slide rail portion 221 is provided with a sliding matching 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 the driving of an external force, so that the sliding portion is disengaged from the sliding matching portion.

[0077] When it is necessary to unlock the driving mechanism 3 and the panel assembly 2 , the operating portion 222 can be operated to apply external force to the operating portion 222 , thereby enabling the sliding limiter 22 to slide from the locking position to the unlocking position.

[0078] In one example, if Figure 4 and Figure 7 As shown, the slide rail portion 221 is a roughly rectangular block structure, and is provided with a slide slot 2211. The operating portion 222 may be a roughly rectangular plate structure.

[0079] The operating part 222 can be a pressing operating part 222 , that is, the driving force is applied by pressing the operating part 222 , and the pressing direction is consistent with the direction in which the sliding limiter 22 slides from the locking position to the unlocking position, so that the inlet and outlet of the sliding groove 2211 face 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 pulling out the operating part 222 , and the pulling direction is consistent with the direction in which the sliding limiter 22 slides from the locked position to the unlocked position, so that the inlet and outlet of the sliding groove 2211 are facing away from the operating part 222 .

[0081] In some exemplary embodiments, the panel 21 is further provided with a guide and positioning portion, such as Figure 7 As shown, the sliding limiter 22 further includes a guide positioning matching portion 223. The guide positioning portion cooperates with the guide positioning matching portion 223 to guide the sliding limiter 22 to slide between the locking position and the unlocking position and to limit the sliding range of the sliding limiter 22.

[0082] This is helpful to improve the consistency of the sliding track of the sliding limiter 22, and to avoid the sliding track of the sliding limiter 22 from deviating or sliding too much, thereby affecting the repeated assembly and disassembly between the panel assembly 2 and the driving mechanism 3.

[0083] In some exemplary embodiments, Figure 7 As shown, the guide positioning portion includes a guide positioning column 212, and the guide positioning matching portion 223 is provided with a guide positioning slot 2231. The guide positioning column 212 is inserted into the guide positioning slot 2231 and can slide relative to the guide positioning slot 2231. The guide positioning column 212 can be, but not limited to, a cylinder or a truncated cone, and the guide positioning slot 2231 can be, but not limited to, a waist-shaped hole groove. When the guide positioning column 212 slides to one end of the guide positioning slot 2231 relative to the sliding stopper 22, the sliding stopper 22 is located in a locked position; when the guide positioning column 212 slides to the other end of the guide positioning slot 2231 relative to the sliding stopper 22, the sliding stopper 22 is located in an unlocked position.

[0084] Of course, the positions of the guide positioning column 212 and the guide positioning slot 2231 may also be exchanged, which can also guide the sliding process of the sliding limiter 22 between the locking position and the unlocking position.

[0085] In some exemplary embodiments, in combination Figures 8 to 11As shown, the sliding fitting portion is configured as a sliding groove 2211 extending along the length direction of the slide rail portion 221, and the sliding portion is configured as a sliding shaft 321. The sliding shaft 321 is configured to be inserted into or out of the sliding groove 2211 along the width direction of the slide rail portion 221. The sliding stopper 22 is configured to slide between a locking position and an unlocking position along the width direction of the slide rail portion 221. The length direction of the slide rail portion 221 can be perpendicular to the extension direction of the rotation axis of the panel 21, and the width direction of the slide rail portion 221 can be consistent with the extension direction of the rotation axis of the panel 21.

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

[0087] The guide positioning matching portion 223 may be a plate-shaped structure. In the length direction of the slide rail portion 221, the length of the guide positioning matching portion 223 may be greater than the operating portion 222 and less than the slide rail portion 221. The guide positioning matching portion 223 is provided with a guide positioning slot 2231 in the middle of the length direction of the slide rail portion 221. The two ends of the guide positioning matching portion 223 are respectively connected to the two elastic arms 231, such as Figure 7 As shown, the other ends of the two elastic arms 231 can respectively abut against the limiting parts 211 (such as limiting posts 2111) on the panel 21. The part (root) where the elastic arm 231 connects to the guide positioning matching part 223 can be appropriately thickened to improve the root strength and reduce the risk of breakage.

[0088] In some exemplary embodiments, the panel 21 is provided with a limiting rib 215, such as Figure 6 and Figure 7 The limiting rib 215 is located on the side of the slide rail portion 221 away from the elastic arm 231 and abuts against the slide rail portion 221, so that the elastic arm 231 is in an elastic deformation state when the sliding limiting member 22 is in the locked position, so as to limit the sliding portion from being separated from the sliding matching portion. The number of the limiting ribs 215 can be two, and the two limiting ribs 215 can be symmetrically arranged on both sides of the operating portion 222.

[0089] In this way, when the sliding stopper 22 is in the locked position, the elastic arm 231 is in a relatively weak elastic deformation state; when the sliding stopper 22 is in the unlocked position, the elastic arm 231 is in a relatively strong elastic deformation state. This is conducive to increasing the driving force required to unlock the panel assembly 2 and the driving mechanism 3, thereby preventing the panel assembly 2 and the driving mechanism 3 from being unlocked due to misoperation.

[0090] In some embodiments, the elastic arm 231 and the sliding stopper 22 are an integrated structure. Figure 7 As shown, the integrated structure is a mirror-symmetrical structure, and the symmetry plane vertically divides the operating portion 222, the slide rail portion 221 and the guide positioning matching portion 223 into two halves.

[0091] In some exemplary embodiments, a limiting groove 213 is provided at one end of the panel 21. Figure 7 The end of the operating portion 222 away from the slide rail portion 221 is provided with a protruding portion 2221, and the operating portion 222 is inserted into the limiting groove 213, as shown in FIG. Figure 7 shown.

[0092] Based on the sliding stopper 22 being in the locking position, the protruding portion 2221 protrudes from the stopper slot 213 and one end of the panel 21. This makes it easier for the user to identify the operation.

[0093] Among them, the operating part 222 can be set to a pressing operating part 222, which can make the sliding limit member 22 slide to the unlocking position under the pressing driving force, and make the protrusion 2221 at least partially retract into the limiting groove 213; or, the operating part 222 can be set to a pulling operating part 222, which can make the sliding limit member 22 slide to the unlocking 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 plate 24 and the panel 21 enclose a receiving groove, and a portion of the sliding stopper 22 is located in the receiving groove. Figure 4 and Fig.11 shown.

[0095] Based on the panel assembly 2 being in the closed position and the sliding fitting sliding to the unlocked position: the sliding portion corresponds to the avoidance groove 241 (such as Fig.12 and Fig.19 As shown), and can pass through the avoidance groove 241 so that the swinging member 32 can be separated from the panel assembly 2 or connected to the panel assembly 2.

[0096] On the one hand, the decorative plate 24 can play a decorative role. When the panel 21 opens the return air outlet, it can block the sliding limiter 22 and other structures (such as the elastic arm 231, the guide positioning matching part 223, the limiter 211 of the panel 21 and the guide positioning part and other structures), which is beneficial to improving the aesthetics of the air conditioner. On the other hand, the decorative plate 24 can also limit the sliding limiter 22, which is beneficial to prevent the sliding limiter 22 from tilting or even detaching from the panel 21, thereby improving the reliability of the sliding limiter 22. In addition, the decorative plate 24 limits the disassembly and assembly position of the swing member 32 and the panel body, so that the swing member 32 and the panel body can only be disassembled and separated or connected and assembled when the panel assembly 2 is in the closed position, which is beneficial to reduce the step difference between the asynchronous stepper motors 31.

[0097] Figures 16 to 19 The connection process between the panel body and the swing member 32 is shown in FIG. Fig.16 and Fig.17 In the process, the stepper motor 31 is at the zero position, the sliding stopper 22 is pressed, and the panel assembly 2 is controlled according to Fig.17 The swing member 32 rotates counterclockwise toward the closed position as indicated by the arrow in the figure, and the sliding shaft 321 of the swing member 32 approaches the avoidance groove 241 of the decorative plate 24. Fig.18 and Fig.19 In the embodiment, the panel assembly 2 is in the closed position, the sliding shaft 321 of the swing member 32 passes through the avoidance groove 241, and the sliding limit member 22 is released, so that the sliding shaft 321 of the swing member 32 can be embedded in the sliding groove 2211 of the sliding limit member 22, completing the connection and assembly process between the driving mechanism 3 and the panel assembly 2.

[0098] On the contrary, when disassembling, Fig.18 and Fig.19 In the state shown, the panel assembly 2 is in the closed position. Press the sliding limiter 22 and control the panel assembly 2 to rotate downward clockwise. The sliding shaft 321 of the swinging member 32 can pass through the avoidance groove 241 to detach from the panel assembly 2, completing the disassembly and separation process of the driving mechanism 3 and the panel assembly 2. Then release the sliding limiter 22 and the panel assembly 2 can be rotated downward 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 can be smaller than the area of ​​the return air outlet, so that the decorative panel 24 can be at least partially embedded in the return air outlet when the panel 21 is in the closed position.

[0100] In one embodiment, the decorative plate 24 is provided with a connection hole 243, such as Fig.12 As shown, the connection hole 243 is arranged corresponding to the limiting column 2111 on the panel 21, and the fastener 244 passes through the connection hole 243 and is fixedly connected to the limiting column 2111, as shown in FIG. Figure 4As shown, the decorative plate 24 is fixedly connected to the panel 21 .

[0101] In some exemplary embodiments, the decorative plate 24 is further provided with an anti-slip rib 242, such as Figure 4 , Fig.11 and Fig.12 The anti-slip rib 242 is located on one side of the slide rail 221 close to the swing member 32 , and the swing member 32 is located between the anti-slip rib 242 and the slide rail 221 , and is configured to limit the swing member 32 from moving in a direction away from the slide rail 221 .

[0102] The anti-slip rib 242 may be roughly in the shape of a rectangular structure with an opening 11 at one end, such as Figure 4 , Fig.11 and Fig.12 As shown, the end of the opening 11 faces the slide rail portion 221. The anti-slip rib 242 can prevent the swing member 32 from moving in the sliding direction of the slide stopper 22 and detaching from the slide stopper 22, thereby facilitating improving the position stability and reliability of the swing member 32.

[0103] In some exemplary embodiments, the anti-slip rib 242 is provided with a plug hole 2421, such as Fig.11 and Fig.12 As shown, the operating portion 222 is inserted into the insertion hole 2421. This can provide a better limiting effect on the sliding limiter 22, which is beneficial to improving the stability and reliability of the sliding limiter 22.

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

[0105] In this way, after the panel assembly 2 is unlocked from the driving mechanism 3, the panel assembly 2 can be completely removed from the panel frame 1, which is convenient for operations such as cleaning.

[0106] In some exemplary embodiments, Figure 3 , Figure 5 and Fig.14 As shown, one of the panel 21 and the panel frame 1 is provided with a shaft sleeve 214, and the other is provided with a rotating shaft 12. The panel 21 is configured to: be able to move relative to the panel frame 1 in a first direction, so that the rotating shaft 12 is inserted into the shaft sleeve 214 so that the panel 21 is assembled to the panel frame 1; and be able to move 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 shaft sleeve 214 so that the panel 21 is separated from the panel frame 1. Fig.13 The arrow in shows the second direction.

[0107] When the panel assembly 2 needs to be disassembled, a sliding driving force can be applied to the sliding stopper 22 to slide the sliding stopper 22 from the locked position to the unlocked position. The external force can be removed, and the sliding column of the swing member 32 will escape from the sliding groove 2211 of the sliding stopper 22 and can escape through the avoidance groove 241 of the decorative plate 24, thereby unlocking the driving mechanism 3 and the panel assembly 2. Then, the panel assembly 2 can be moved along the second direction, such as Fig.13 As shown by the arrow direction in FIG. 2 , the rotating shaft 12 is disengaged from the shaft sleeve 214, and the panel assembly 2 can be disassembled.

[0108] On the contrary, during installation, the panel assembly 2 can be first moved along the first direction so that the rotating shaft 12 is inserted into the shaft sleeve 214; then a sliding driving force is applied to the sliding limit member 22 to slide the sliding limit member 22 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 avoidance groove 241 of the decorative panel 24 and reaches the notch of the sliding groove 2211. Then, the external force is removed, and the sliding limit member 22 can be 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 driving mechanism 3.

[0109] Of course, the detachable matching mode between the panel frame 1 and the panel 21 is not limited to this. For example, the panel frame 1 and the panel 21 may both be provided with a shaft sleeve 214. The assembly between the panel frame 1 and the panel 21 is achieved by inserting the rotating shaft 12 independent of the panel frame 1 and the panel 21 into the shaft sleeve 214 of the panel frame 1 and the panel 21, and the panel assembly 2 is removed from the panel frame 1 by pulling out the rotating shaft 12.

[0110] In some exemplary embodiments, the number of the rotating shaft 12 and the number of the sleeves 214 are both arranged in a plurality along the axial direction of the rotating shaft 12, and the plurality of rotating shafts 12 are arranged correspondingly to the plurality of sleeves 214, and the spacing between adjacent sleeves 214 is greater than the length of the rotating shaft 12, such as Fig.14 shown.

[0111] This can reduce the movement range of the panel assembly 2 when disassembling and assembling the panel assembly 2, which is helpful to reduce the operating difficulty for the operator.

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

[0113] Based on the anti-slip fitting being in the locked state, the anti-slip fitting restricts the panel 21 from moving in the second direction to restrict the shaft 12 from slipping out of the sleeve 214. Based on the anti-slip fitting being in the unlocked state, the limiter releases the restriction on the panel 21, allowing the panel 21 to move in the second direction to allow the shaft 12 to slip out of the sleeve 214.

[0114] The provision of the anti-dropout fitting can prevent the rotating shaft 12 from falling out of the shaft sleeve 214 in a natural state, causing the panel assembly 2 to fall off. The anti-dropout fitting can be in the form of, but not limited to, a buckle, a buckle, a lock, and the like.

[0115] In one embodiment, a plurality of sleeves 214 are provided at one end of the panel 21. Figure 3 and Figure 5 As shown, multiple shaft sleeves 214 are integrally formed with the panel 21. The panel 21 may also be provided with multiple reinforcing ribs to strengthen the shaft sleeves 214. Multiple rotating shafts 12 and anti-slip limiters 13 are integrally formed with the panel frame 1. The anti-slip limiter 13 is a buckle, such as Fig.14 As shown, when the anti-disengagement fitting is in the locked state, the anti-disengagement fitting is located on the other side of the insertion opening of the sleeve 214 to limit the sleeve 214 from moving in the direction of disengaging from the rotating shaft 12 (i.e., the second direction). By moving the buckle upward, the buckle can be deviated from the movement direction of the sleeve 214 to the unlocked state, and the panel assembly 2 can be moved along the second direction and removed.

[0116] On the contrary, during installation, the buckle can also be bent until the shaft 12 is inserted into the shaft sleeve 214 to achieve the assembly of the panel assembly 2 and the panel frame 1 bracket.

[0117] The number of the anti-dropping limiter 13 can be one or more. When only one is provided, the operation difficulty of the operator can be reduced and the convenience of disassembly and assembly of the panel assembly 2 can be improved.

[0118] An embodiment of the present application further provides an air conditioner, comprising a panel device and a control device as in any one of the above embodiments, wherein 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 the embodiment of the present application includes the panel device of any one of the above embodiments, and thus has the above-mentioned beneficial effects, which will not be described in detail here.

[0120] The air conditioner may be, but is not limited to, an embedded air conditioner, and the embedded air conditioner may be, but is not limited to, a kitchen air conditioner.

[0121] In some exemplary embodiments, based on the panel assembly 2 rotating from the open position to the closed position, the rotation angle of the stepper motor 31 is recorded as a; △a (such as Fig. 20 Δa can be in the range of, but not limited to, 3° to 5°.

[0122] The control device is set up to:

[0123] Based on the air conditioner being in the on state, upon receiving the shutdown command, a command with a closing angle of a+△a is sent to all the stepper motors 31; based on the execution of all the stepper motors 31, the current positions of all the stepper motors 31 are set as the zero position;

[0124] Based on the air conditioner being in the off state, upon receiving the power-on command, a command for closing the angle △a is sent to all stepper motors 31; based on the execution of all stepper motors 31, the current position of all stepper motors 31 is set to the zero position; and a command for opening the angle a is sent to all stepper motors 31.

[0125] When the air conditioner is in the on state, the panel assembly 2 is in the open position. When receiving the shutdown command, the control device theoretically needs to send a command with a closing angle of a to all stepper motors 31. However, considering that there may be a synchronization problem between multiple stepper motors 31, a command with a closing angle of a+△a is sent to all stepper motors 31. The extra △a can ensure that all stepper motors 31 can be reset and rotated to a position where they cannot continue to rotate (because they are limited by the zero point limit structure), thereby ensuring that all stepper motors 31 can be reset and rotated to the zero point position. When all stepper motors 31 have completed execution, the current position of all stepper motors 31 is set to the zero point position. In this way, after each shutdown, all stepper motors 31 are located at the zero point position, synchronization is achieved, and the service life of the stepper motors 31 is not affected.

[0126] When the air conditioner is in the off state, the panel assembly 2 is in the closed position. When receiving the power-on command, the control device theoretically needs to send a command with an opening angle of a to all stepper motors 31. However, considering that there may be a problem of asynchrony between multiple stepper motors 31, a command with a closing angle of △a is first sent to all stepper motors 31. By resetting and rotating △a first, it can be ensured that all stepper motors 31 can be reset and rotated to a position where they cannot continue to rotate (because they are limited by the zero-point limit structure), thereby ensuring that all stepper motors 31 can be reset and rotated to the zero position. When all stepper motors 31 have completed execution, the current position of all stepper motors 31 is set to the zero position. Then send a command with an opening angle of a to all stepper motors 31. In this way, after each startup, all stepper motors 31 are first synchronized and then start to operate, which is conducive to the synchronous rotation of multiple stepper motors 31.

[0127] In this way, the virtual position difference is compensated by the operation control method, so that the air conditioner can achieve the synchronization purpose every time it is turned on or off, which is beneficial to greatly reduce the step difference between the asynchronous stepper motors 31, so that the number of steps of each stepper motor 31 can be controlled within a very small step range, thereby helping to reduce the stall time of the stepper motor 31 and improve the service life of the stepper motor 31.

[0128] In some exemplary embodiments, the control device is further configured to: based on the first power-on of the air conditioner after power failure, send an instruction with a closing angle of a+a to all stepper motors 31; based on the completion of execution of all stepper motors 31, set the current position of all stepper motors 31 to the zero position.

[0129] After power failure, the air conditioner may be in a maintenance state, and the panel assembly 2 may be bent to a relatively large angle artificially. Therefore, when the power is turned on for the first time after power failure, the closing angle range of the closing angle instruction sent to all stepper motors 31 is relatively large (a+a), so as to ensure that all stepper motors 31 can be reset and rotated to the zero position. When all stepper motors 31 have completed execution, the current position of all stepper motors 31 is set to the zero position. Due to the process of resetting the zero position when powering on for the first time after power failure, the number of overstepping steps is large, which will cause the stepper motor 31 to be blocked for a long time. However, since in the embodiment of the present application, the air conditioner can be synchronized every time it is turned on and off, and it is not necessary to power off and then power on every time the zero position is reset, the zero position reset process of the first power-on after power failure is rarely used, and thus the impact on the life of the stepper motor 31 is very small.

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

[0131] Based on the air conditioner being in the on state, receiving the shutdown command, sending a command with a closing angle of a+△a to all stepper motors 31; based on the execution of all stepper motors 31, setting the current position of all stepper motors 31 as the zero position; and / or

[0132] Based on the air conditioner being in the off state, upon receiving the power-on command, a command for closing the angle △a is sent to all the stepper motors 31; based on the execution of all the stepper motors 31, the current positions of all the stepper motors 31 are set as the zero position; and a command for opening the angle a is sent to all the 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 the execution of all stepper motors 31, the current positions of all stepper motors 31 are set as zero positions.
