[0047] 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.

[0048] like Figures 1 to 18 As shown, an embodiment of the present application provides a panel device that can be used for an air conditioner, such as 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.

[0049] like Figure 7 As shown, the panel device includes: a panel body 1, a return air panel 2 and a driving mechanism 3.

[0050] The panel body 1 is provided with a return air outlet 11, such as Figure 6 The panel body 1 can be connected to the casing of the indoor unit of the air conditioner.

[0051] 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.

[0052] like Fig.12 As shown, the driving mechanism 3 includes a driving member 31 disposed on the panel body 1 and a crank connecting rod structure connected to the driving member 31. The driving member 31 can be, but is not limited to, a stepping motor. The crank connecting rod structure is connected to the return air panel 2 and is configured to drive the return air panel 2 to the open position (such as the open position) of the return air outlet 11 under the drive of the driving member 31. Figure 5 , Fig.14 and Fig.15 ) and the closed position of the return air outlet 11 (as shown Figure 4 , Fig.11 and Fig.12 as shown).

[0053] 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.14 and Fig.15 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.11 and Fig.12 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.

[0054] Furthermore, compared to driving the return air panel 2 to rotate between the open position and the closed position through a rope, the present solution drives the return air panel 2 to rotate between the open position and the closed position through a crank-connecting rod structure, and has a higher structural strength and is less prone to breakage.

[0055] 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.

[0056] 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. Figures 1 to 6As shown, the panel device may further include an air guide mechanism 6 disposed at the air outlet, and the air guide mechanism 6 may be detachably connected to the panel body 1 (e.g., connected by fasteners or snap-fitted). The panel device may further 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.

[0057] In some exemplary embodiments, the crank-connecting rod structure includes: a crank 32 and a connecting rod 33, such as Figure 8 and Fig.12 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 rotatably connected to the return air panel 2.

[0058] 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.

[0059] In some exemplary embodiments, a positioning slot 331 is provided at one end of the connecting rod 33. Figure 8 As shown, a first pin is disposed at the other end of the crank 32. The first pin is inserted into the positioning slot 331 and can rotate relative to the positioning slot 331, and can slide relative to the positioning slot 331 between a first position and a second position.

[0060] Based on the first pin shaft sliding to the first position relative to the positioning slot 331, Figures 14 to 16 As shown, the return air panel 2 rotates to the open position. Based on the first pin shaft sliding to the second position relative to the positioning slide slot 331, the return air panel 2 rotates to the closed position, as shown in FIG. Figures 11 to 13 shown.

[0061] Among them, the positioning slot 331 can be a waist-shaped hole, such as Figure 8 When the first pin slides to the lower end of the positioning slot 331, it slides to the first position, as shown in FIG. Fig.16 As shown, the return air panel 2 is switched to the open state, that is, rotated to the open position; when the first pin slides to the upper end of the positioning slot 331, as shown Fig.13As shown, the return air panel 2 is switched to the closed state, i.e., rotated to the closed position, by sliding the positioning slot 331 to the second position. By controlling the length of the positioning slot 331, the opening angle of the return air panel 2 when in the open position can be controlled, and the opening angle of the return air panel 2 when in the open position can be determined according to the air volume demand of the air conditioner.

[0062] In some exemplary embodiments, the panel device further includes a sliding stopper 7, such as Figure 7 The sliding stopper 7 includes a sliding seat 71 and a rotating connection portion connected to the sliding seat 71, as shown in FIG. Fig.10 As shown. The other end (lower end) of the connecting rod 33 is rotatably connected to the return air panel 2 via a rotating connection portion. The sliding seat 71 is limited to the return air panel 2 and can slide between a locked position and an unlocked position relative to the return air panel 2. Fig.10 In the figure, the double-headed arrow indicates the sliding direction of the sliding limiter 7.

[0063] Based on the sliding limiter 7 being in the locked position, Fig.13 and Fig.16 As shown, the rotation connection portion is connected to the other end (lower end) of the connecting rod 33.

[0064] Based on the sliding stopper 7 being in the unlocking position, the rotating connecting portion is disengaged from the other end (lower end) of the connecting rod 33, as shown in FIG. Fig.18 As shown, the return air panel 2 and the driving mechanism 3 are unlocked.

[0065] Thus, the drive mechanism 3 and the return air panel 2 form a separable matching form. When the return air panel 2 and the return air outlet 11 area need to be inspected, 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 approximately 90° (which can be called a maintenance state) under the action of gravity, which greatly facilitates the operator to clean or inspect the return air panel 2, and also facilitates the operator to clean or inspect the return air outlet 11 area and the components inside the return air outlet 11.

[0066] Furthermore, when the return air panel 2 is in the open position, the connecting rod 33 can be separated from the return air panel 2 by moving the sliding stopper 7 to the unlocking position. Conversely, the connecting rod 33 can be installed with the return air panel 2 by moving the sliding stopper 7 to the locking position. The disassembly and assembly process is simple and fast, and is easy to operate.

[0067] In some exemplary embodiments, in combination Fig.10 , Fig.13 and Fig.16As shown, the rotation connection portion is configured as a second pin shaft 72 provided at one end of the sliding seat 71, and the other end (lower end) of the connecting rod 33 is provided with a first pin hole 3332. The return air panel 2 is provided with a second pin hole 221. The second pin shaft 72 is configured to be able to be inserted into the first pin hole 3332 and the second pin hole 221 along a first direction, and to be able to be removed from the first pin hole 3332 and the second pin hole 221 along a second direction opposite to the first direction. The first direction and the second direction can be consistent with the extension direction of the rotation axis of the return air panel 2.

[0068] Compared with the solution in which the second pin shaft 72 is only inserted into the first pin hole 3332 , in this solution, the second pin shaft 72 is inserted into the first pin hole 3332 and the second pin hole 221 , which is beneficial to improving the connection reliability between the return air panel 2 and the connecting rod 33 .

[0069] Of course, since the sliding stopper 7 is limited to the return air panel 2, the second pin shaft 72 may also be only inserted into the first pin hole 3332. The rotatable connection method of the rotating connection part and the connecting rod 33 is not limited to the matching method of the second pin shaft 72 and the first pin hole 3332, and the positions of the second pin shaft 72 and the first pin hole 3332 may also be exchanged, or other structural matching methods may be adopted.

[0070] In some exemplary embodiments, Fig.10 As shown, the return air panel 2 is provided with a stopper 21 and a connecting lug 22 arranged opposite to each other. The second pin hole 221 is provided at the connecting lug 22. The sliding seat 71 is limited between the stopper 21 and the connecting lug 22. Based on the sliding limiter 7 sliding to the unlocking position, the sliding seat 71 and the stopper 21 are stopped and matched. The stopper 21 can be, but is not limited to, a baffle 333, a baffle rib, a baffle block and other structural forms.

[0071] In this way, the sliding limiter 7 can play a better limiting role, which is beneficial to preventing the sliding limiter 7 from sliding excessively and affecting the repeated disassembly and assembly of the return air panel 2 and the connecting rod 33.

[0072] In some exemplary embodiments, in combination Fig.10 , Fig.13 and Fig.16 As shown, the other end (lower end) of the connecting rod 33 is provided with a connecting seat 332. The connecting seat 332 is provided with two connecting plates 3321 arranged relatively spaced apart, and a receiving groove is formed between the two connecting plates 3321. The receiving groove is configured to receive the connecting lug 22. Both connecting plates 3321 are provided with a first pin hole 3332 corresponding to the second pin hole 221.

[0073] In other words, the connecting lug 22 can be inserted into the connecting seat 332, so that the second pin shaft 72 passes through the three pin holes in sequence. In this way, the connecting lug 22 and the connecting seat 332 can stop each other, which is conducive to preventing the connecting rod 33 and the return air panel 2 from axial relative movement, thereby facilitating the position stability of the second pin shaft 72, and further facilitating the connection reliability between the connecting rod 33 and the return air panel 2.

[0074] In some exemplary embodiments, Fig.10 As shown, the return air panel 2 is provided with a first clamping portion 26 and a guide portion 23. The first clamping portion 26 is configured to clamp the sliding seat 71 to the return air panel 2. The guide portion 23 is configured to guide the sliding process of the sliding seat 71.

[0075] The sliding seat 71 may be, but is not limited to, an L-shaped plate structure, and the connecting lug 22 may be vertically arranged at one end of the sliding seat 71. The first clamping portion 26 may be, but is not limited to, buckles arranged on both sides of the sliding seat 71, and the buckles on both sides clamp the horizontal part of the sliding seat 71 to prevent the sliding seat 71 from detaching from the return air panel 2. The guide portion 23 may be, but is not limited to, guide plates arranged on both sides of the sliding seat 71, and the guide plates on both sides clamp the sliding seat 71 to ensure that the sliding seat 71 slides in a straight line. In this way, the pre-fixation of the sliding limiter 7 is achieved. Figure 7 As shown, the components shown in the dashed box can be pre-assembled into a module.

[0076] In some exemplary embodiments, Fig.10 As shown, the driving mechanism 3 further includes a first cover 34 and a second cover 35, which are connected to each other and enclose a mounting cavity. The driving member 31 is located in the mounting cavity, and the mounting cavity is provided with an escape notch 36 for the connecting rod 33 to extend out of the mounting cavity. 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.

[0077] The connecting rod 33 is provided with a baffle 333. Fig.10 As shown. Based on the return air panel 2 being in the open position, the baffle 333 blocks the avoidance gap 36, as shown Fig.16 As shown. Based on the return air panel 2 being in the closed position, the other end of the connecting rod 33 blocks the avoidance gap 36, as shown Fig.13 shown.

[0078] This can prevent the installation cavity from being contaminated, provide better protection for the drive mechanism 3 , and help improve the reliability of the drive member 31 .

[0079] In some exemplary embodiments, the driving member 31 is fixed to the first cover 34, and the second cover 35 is provided with an arc-shaped slide groove 351, such as Fig.10As shown. The first pin of the crank 32 is inserted into the arc-shaped slot 351 and can slide along the arc-shaped slot 351. This is conducive to improving the position stability and use reliability of the crank 32. The first pin can pass through the positioning slot 331 of the connecting rod 33 and be inserted into the arc-shaped slot 351.

[0080] In some exemplary embodiments, the return air panel 2 is detachably connected to the panel body 1 .

[0081] 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.

[0082] In some exemplary embodiments, Figure 7 As shown, the panel body 1 and the return air panel 2 are detachably connected by a rotating connection member 4. The rotating connection member 4 is detachably connected to the panel body 1. A third pin hole 24 is provided at one end of the return air panel 2. Fig.10 The rotating connecting member 4 is provided with a third pin 41, as shown in FIG. Fig. 9 As shown, the third pin shaft 41 is inserted into the third pin hole 24 and can rotate relative to the third pin hole 24 .

[0083] 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.

[0084] 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 .

[0085] In some exemplary embodiments, the panel body 1 is provided with a second clamping portion, and the return air panel 2 is provided with a plurality of third pin holes 24. The rotating connecting member 4 includes: a clamping fitting portion 42 for matching with the second clamping portion and two third pin shafts 41 symmetrically arranged at both ends of the clamping fitting portion 42, such as Fig. 9 and Fig.10 The two third pin shafts 41 are arranged opposite to each other and are respectively inserted into the corresponding third pin holes 24. The return air panel 2 may also be provided with a partition plate 25, which is located between the two third pin shafts 41 to separate the two third pin shafts 41.

[0086] 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 72 is connected to the lower end of the elastic arm. By bending the elastic arm, the two second pin shafts 72 can be inserted into the corresponding pin holes respectively.

[0087] As for the specific structural form of the second clamping portion and the clamping matching portion 42, there is no restriction, for example, it can be various forms such as 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, etc.

[0088] 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.

[0089] In some exemplary embodiments, Figure 7 As shown, there are two driving mechanisms 3, and the two driving mechanisms 3 extend along the extension direction of the rotation axis of the return air panel 2. This is conducive to the balanced force of the return air panel 2.

[0090] The embodiment of the present application also provides an air conditioner, including a panel device as in any one of the above embodiments, thus having all the above beneficial effects, which will not be repeated here.
