In order to meet the air intake needs, the return air vent is always in an open state regardless of whether the air conditioner is running or not, which is easy to hide dirt and also affects the overall aesthetics of the interior decoration. Utility Model Content

[0003] The technical problem to be solved by the present application is to provide a panel device and an embedded air conditioner, which can realize a fully closed state of the return air outlet when not in operation, thereby helping to improve the cleanliness of the return air outlet and also helping to improve the overall aesthetics of interior decoration.

[0041] 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.

[0042] like Figures 1 to 14 As shown, an embodiment of the present application provides a panel device for an embedded air conditioner. The embedded air conditioner can be an indoor unit of an air conditioner or an all-in-one unit. The embedded air conditioner can be embedded in a ceiling (for example, embedded in a suspended ceiling) or embedded in other installation carriers. The following explanation is based on the example of an embedded air conditioner embedded in a ceiling. After leaving the factory, when the air conditioner is assembled, the panel body 1 is roughly horizontal.

[0043] like Figure 7 , Fig.10 and Fig.13 As shown, the panel device includes: a panel body 1, a return air panel 2 and a driving mechanism 3.

[0044] The panel body 1 is provided with an air return port 11. The panel body 1 can be connected to the casing of the indoor unit of the air conditioner.

[0045] The return air panel 2 is rotatably connected to the panel body 1 and is configured to open and close the return air port 11. A grille and a filter may also be provided at the return air port 11. The grille and the filter are located on the downstream side of the return air panel 2 and may be shielded by the return air panel 2.

[0046] The driving mechanism 3 is configured to be connected to the return air panel 2 to drive the return air panel 2 to open the return air port 11 (eg, Figure 5 , Fig.12 and Fig.13 ) and the closed position of the return air outlet 11 (as shown Figure 4 , Fig. 9 and Fig.10 ) and can be separated from the return air panel 2 so that the return air panel 2 can be rotated to the maintenance position (as shown) Figure 6 shown).

[0047] The panel device provided in the embodiment of the present application can open or close the return air vent 11 on the panel body 1 through the return air panel 2. In this way, when the embedded air conditioner needs to be turned on, the driving mechanism 3 can drive the return air panel 2 to open the return air vent 11 (such as Figure 5 , Fig.12 and Fig.13 As shown in FIG. 1 ), the indoor air flow can enter the air conditioner through the return air vent 11 to ensure the normal use of the air conditioner. When the air conditioner does not need to be turned on, the drive mechanism 3 can drive the return air panel 2 to close the return air vent 11 (as shown in FIG. 1 ). Figure 4 , Fig. 9 and Fig.10 As shown), dust, oil, steam and other external impurities can only stay outside the air conditioner, which is beneficial to improving the cleanliness of the return air outlet 11 area, and the return air outlet 11 can be fully closed when not in use, which is beneficial to improving the consistency and overall aesthetics of the interior decoration.

[0048] In addition, the drive mechanism 3 and the return air panel 2 are arranged in a separable matching form. When the return air panel 2 and the return air outlet 11 area need to be repaired, the drive mechanism 3 can be separated from the return air panel 2, and the return air panel 2 can be rotated to an inspection position of about 90° (which can be called a maintenance state, such as Figure 6 As shown), it is greatly convenient for the operator to clean or repair the return air panel 2, and it is also convenient for the operator to clean or repair the return air outlet 11 area and the components inside the return air outlet 11.

[0049] Among them, combined Figures 1 to 6 As shown, the return air port 11 can be located at the rear of the panel body 1, the front end of the return air panel 2 is rotatably connected to the panel body 1, and the rear end of the return air panel 2 can be rotated downward to open and rotated upward to close. The crank connecting rod structure can be connected to the middle position of the return air panel 2 in the front-to-back direction.

[0050] Combination Figures 1 to 6 As shown, the panel body 1 may also be provided with an air outlet, and the air outlet may be located at the front of the panel body 1. The panel device may also include an air guide mechanism 6 provided at the air outlet, and the air guide mechanism 6 may be detachably connected to the panel body 1 (such as connected by fasteners or snap-fitted). The panel device may also include a cover plate 5. The cover plate 5 may be provided with a vent corresponding to the air outlet, and together with the return air panel 2, shield the lower end of the panel body 1, as an appearance component of the panel device, exposed to the ceiling, while the panel body 1 may be hidden inside the ceiling.

[0051] In some exemplary embodiments, Figure 7As shown, the driving mechanism 3 includes a driving member 31 provided on the panel body 1 and a crank connecting rod structure connected to the driving member 31. The driving member 31 may be, but is not limited to, a stepping motor. The crank connecting rod structure is configured to be connected to the return air panel 2 so as to drive the return air panel 2 to rotate between an open position and a closed position under the drive of the driving member 31, and to be separated from the return air panel 2 so that the return air panel 2 can rotate to an inspection position.

[0052] Compared with driving the return air panel 2 to rotate between the open position and the closed position through a rope, this solution drives the return air panel 2 to rotate between the open position and the closed position through a crank connecting rod structure, and the structural strength is higher and it is not easy to break.

[0053] In some exemplary embodiments, Figure 7 , Figure 8 , Fig.10 As shown, the crank-connecting rod structure includes: a crank 32 and a connecting rod 33. One end (upper end) of the crank 32 is connected to the driving member 31, and the other end (lower end) of the crank 32 is connected to one end (upper end) of the connecting rod 33 and can rotate and slide relative to the connecting rod 33, and the other end (lower end) of the connecting rod 33 is detachably matched with the return air panel 2.

[0054] When the driving member 31 rotates, the upper end of the crank 32 rotates synchronously with the output shaft 311 of the driving member 31, and the lower end of the crank 32 rotates around the output shaft 311, generating a partial movement in the vertical direction, driving the connecting rod 33 to generate a partial movement in the vertical direction, and the connecting rod 33 drives the return air panel 2 to generate a partial movement in the vertical direction, thereby realizing the return air panel 2 closing upwards and opening downwards.

[0055] In some exemplary embodiments, the other end (lower end) of the crank 32 is provided with a positioning slot 321, such as Figure 8 One end (upper end) of the connecting rod 33 is provided with a first pin 331, as shown in FIG. Figure 8 The first pin shaft 331 is inserted into the positioning slide slot 321 and can rotate relative to the slide slot, and can slide relative to the positioning slide slot 321 between a first position and a second position.

[0056] Based on the first pin shaft 331 sliding to the first position relative to the positioning slot 321, Fig.14 As shown, the return air panel 2 rotates to the open position. Based on the first pin shaft 331 sliding relative to the positioning slide groove 321 to the second position, as shown in FIG. Fig.11 As shown, the return air panel 2 is rotated to the closed position.

[0057] Among them, the positioning slot 321 can be a waist-shaped hole, such as Figure 8 When the first pin shaft 331 slides to the lower end of the positioning slot 321, it slides to the first position, as shown in FIG. Figure 12 to Figure 14As shown, the return air panel 2 is switched to the open state, that is, rotated to the open position; when the first pin shaft 331 slides to the upper end of the positioning slide groove 321, it slides to the second position, as shown in FIG. Figures 9 to 11 As shown, the return air panel 2 is switched to the closed state, that is, rotated to the closed position. By controlling the length of the positioning slide slot 321, the opening angle of the return air panel 2 when it is in the open position can be controlled, and the opening angle of the return air panel 2 when it is in the open position can be determined according to the air volume demand of the air conditioner.

[0058] In some exemplary embodiments, the other end (lower end) of the connecting rod 33 is provided with a supporting portion 332, such as Figure 7 and Figure 8 As shown, the return air panel 2 is provided with a supporting and matching portion 21. The supporting portion 332 is configured to: be able to support and match with the supporting and matching portion 21 to support the return air panel 2, and be able to detach from the supporting and matching portion 21 to enable the return air panel 2 to be unlocked from the driving mechanism 3.

[0059] Compared with the hard connection method, the support and matching method is easy to unlock, which is beneficial to reduce the difficulty of separating the return air panel 2 and the driving mechanism 3.

[0060] In some exemplary embodiments, the support portion 332 includes a support boss 3321, such as Figure 8 As shown, the supporting mating portion 21 includes a hook plate 211. The hook plate 211 includes a connecting plate 2111 and a hanging ear 2112 connected to the top of the connecting plate 2111. The supporting boss 3321 can be an arc-shaped boss, and the hanging ear 2112 can be an arc-shaped hanging ear 2112, such as Fig.11 and Fig.14 Reinforcement ribs may be provided at the front and rear ends of the hanging ear 2112 to improve the structural strength.

[0061] The supporting boss 3321 is configured to be able to be inserted into the lower side of the hanging ear 2112 along a first rotation direction (forward rotation) relative to the return air panel 2 and to cooperate with the hanging ear 2112 to support the return air panel 2, and to be able to be detached from the hanging ear 2112 along a second rotation direction (backward rotation) opposite to the first rotation direction relative to the return air panel 2 to disengage the return air panel 2 from the driving mechanism 3.

[0062] Among them, Figure 8 As shown, the connecting plate 2111 can be vertically arranged on the upper plate surface of the return air panel 2, and the hanging ear 2112 can be horizontally placed on the upper end of the connecting plate 2111, so that the hook plate 211 as a whole can be in an inverted L shape. In this way, the hook plate 211 can be hung on the supporting boss 3321, so that the connecting rod 33 can support the return air panel 2, thereby driving the return air panel 2 to rotate between the open position and the closed position. When the supporting boss 3321 rotates out of the hook plate 211, the return air panel 2 and the driving mechanism 3 can be separated and unlocked, and the operation is relatively simple and convenient.

[0063] In some exemplary embodiments, Figure 8 As shown, there are two hook plates 211 , which are arranged at intervals relative to each other. There are two supporting bosses 3321 , which are arranged correspondingly to the two hook plates 211 .

[0064] This helps prevent the hook plate 211 and the support boss 3321 from moving relative to each other in the extension direction of the rotation axis of the return air panel 2 and thus separating, thereby helping to improve the matching reliability between the connecting rod 33 and the return air panel 2, and further helping to improve the reliability of the return air panel 2 during use.

[0065] The two support bosses 3321 can be an integral structure with the connecting rod 33 (for example, integrally formed by injection molding), or a split assembly structure. The two hook plates 211 can be an integral structure with the return air panel 2 (for example, integrally formed by injection molding), or a split assembly structure. The main body of the connecting rod 33 can be roughly fan-shaped, or include two arms, and the two arms and the support portion 332 enclose a fan-shaped structure, which is conducive to improving the structural strength of the connecting rod 33.

[0066] In some exemplary embodiments, Figure 8 As shown, the support matching portion 21 further includes a baffle 212, which is connected to the hook plate 211 and encloses a limit groove 213 and an inlet and outlet 214 and an escape opening 215 connected to the limit groove 213. The support portion 332 further includes a limit boss 3332 connected to the support boss 3321, and the limit boss 3332 is configured to be abutted against the hanging ear 2112 to limit the support boss 3321 from rotating relative to the hanging ear 2112 in the second rotation direction (rotating backward) and disengaging from the hanging ear 2112.

[0067] The inlet and outlet 214 is configured to allow the support boss 3321 to be inserted to the lower side of the hanging ear 2112 along the first rotation direction (forward rotation) or to be detached from the hanging ear 2112 along the second rotation direction after the support matching portion 21 moves upward relative to the support portion 332 so that the hanging ear 2112 avoids the limiting boss 3332.

[0068] The avoidance opening 215 is configured to accommodate the limiting boss 3332 after the supporting boss 3321 is inserted into the lower side of the hook 2112; the baffle 212 is configured to be able to cooperate with the limiting boss 3332 to limit the supporting boss 3321 from rotating relative to the hook 2112 along the first rotation direction and disengaging from the hook 2112.

[0069] When the driving mechanism 3 and the return air panel 2 are in cooperation: Fig.11 and Fig.14As shown, the supporting boss 3321 is located at the lower side of the hanging ear 2112, providing an upward supporting force to the hanging ear 2112, thereby supporting the return air panel 2; the limiting boss 3332 is located at the front side of the hanging ear 2112, and can stop against the rear end of the hanging ear 2112 to prevent the supporting boss 3321 from rotating backward relative to the hanging ear 2112 and detaching from the hanging ear 2112; the baffle 212 is located at the rear side of the limiting boss 3332, and can have a certain reserved gap with the limiting boss 3332, but can stop against the rear end of the limiting boss 3332 to prevent the supporting boss 3321 from rotating forward relative to the hanging ear 2112 and detaching from the hanging ear 2112.

[0070] When maintenance is required, the return air panel 2 can be turned upwards in the open state (such as Fig.14 X direction), so that the ear 2112 moves to the upper side of the limiting boss 3332, the limiting boss 3332 and the supporting boss 3321 are both located in the limiting groove 213, and can be rotated backward (such as Fig.14 The connecting rod 33 (in the middle Y direction) causes the supporting portion 332 to rotate backward until the supporting boss 3321 and the limiting boss 3332 are both out of the limiting groove 213, thereby realizing the separation of the connecting rod 33 from the return air panel 2, and the return air panel 2 can be rotated to the maintenance position under the action of gravity.

[0071] On the contrary, when assembly is required, the return air panel 2 can be rotated upward first (such as Fig.14 X direction), the ear 2112 moves to the upper side of the limiting boss 3332, and then the connecting rod 33 is rotated forward (such as Fig.14 The support portion 332 is rotated forward until both the support boss 3321 and the limiting boss 3332 enter the limiting groove 213, and then the return air panel 2 is rotated downward or the return air panel 2 is directly lowered so that the limiting boss 3332 is stuck in the avoidance opening 215.

[0072] In some exemplary embodiments, Figure 8 As shown, the driving mechanism 3 further includes a first cover 34 and a second cover 35, and the first cover 34 and the second cover 35 are connected to each other and enclose a sealed cavity. The main body of the driving member 31 is fixed in the sealed cavity, and the output shaft 311 of the driving member 31 is passed through the second cover 35 and connected to the crank connecting rod structure. The first cover 34 and the second cover 35 are fixed to the panel body 1, and the driving member 31 is indirectly fixed to the panel body 1 through the first cover 34 and the second cover 35.

[0073] In this way, the sealing cavity can be prevented from being contaminated, and the driving member 31 can be better protected, which is beneficial to improving the reliability of the driving member 31 .

[0074] The driving member 31 can be fixed on the first cover body 34 , and a connecting hole can be provided on the second cover body 35 . The output shaft 311 of the driving member 31 extends out of the sealed cavity through the connecting hole and is connected to the rotating shaft of the crank 32 .

[0075] In some exemplary embodiments, the return air panel 2 is detachably connected to the panel body 1 .

[0076] In this way, when the return air panel 2 is separated and unlocked from the driving mechanism 3, the return air panel 2 can be completely removed from the panel body 1, which is convenient for operations such as cleaning.

[0077] In some exemplary embodiments, the panel body 1 and the return air panel 2 are detachably connected via a rotating connection member 4. The rotating connection member 4 is detachably connected to the panel body 1, a pin hole 22 is provided at one end of the return air panel 2, and the rotating connection member 4 is provided with a second pin shaft 41, which is inserted into the pin hole 22 and can rotate relative to the pin hole 22.

[0078] When the return air panel 2 needs to be disassembled, the return air panel 2 can be disassembled by simply removing the rotating connector 4 from the panel body 1. When the return air panel 2 needs to be installed, the rotating connector 4 can be installed on the panel body 1. This solution realizes the disassembly and assembly of the return air panel 2 by disassembling and assembling the rotating connector 4, which has the advantages of being simple and fast.

[0079] There may be multiple rotating connectors 4 , which are spaced apart along the extension direction of the rotation axis of the return air panel 2 , which is beneficial to improving the connection reliability between the return air panel 2 and the panel body 1 .

[0080] In some exemplary embodiments, the panel body 1 is provided with a snap-on portion, and the return air panel 2 is provided with a plurality of pin holes 22, such as Figure 8 The rotating connecting member 4 comprises: a snap-fitting portion 42 for matching with the snap-fitting portion and two second pins 41 symmetrically arranged at both ends of the snap-fitting portion 42, as shown in FIG. Figure 8 As shown, the two second pin shafts 41 are arranged opposite to each other and are respectively inserted into the corresponding pin holes 22. The return air panel 2 may also be provided with a partition plate, which is located between the two second pin shafts 41 to separate the two second pin shafts 41. Figure 7 As shown, the components shown in the dashed box can be pre-assembled into a module.

[0081] This helps prevent the rotating connector 4 from axially moving relative to the return air panel 2, thereby improving the connection reliability between the rotating connector 4 and the return air panel 2. The snap-fitting portion 42 can be provided with an elastic arm, and the second pin shaft 41 is connected to the lower end of the elastic arm. By bending the elastic arm, the two second pin shafts 41 can be inserted into the corresponding pin holes 22 respectively.

[0082] As for the specific structural form of the snap-fitting part and the snap-fitting matching part 42, there is no restriction, for example, it can be the structural matching of a buckle and a slot, the structural matching of a hook and a hole, the structural matching of a clamp and a hole, and the like.

[0083] Of course, the connection method between the rotating connector 4 and the panel body 1 is not limited to snap connection, and can also be fastener connection or other detachable connection methods.
