[0027] The panel assembly 100 of an air conditioner according to a first aspect of the present invention is described below with reference to the accompanying drawings.

[0028] According to an embodiment of the present utility model, the panel assembly 100 of the air conditioner, such as Figures 1-3 As shown, the panel assembly 100 includes: a first panel 1 and a second panel 2. The first panel 1 includes a grille portion 11. The second panel 2 is provided with a placement groove 2a and a hollow area 2b communicating with the placement groove 2a. The first panel 1 is located on one side of the second panel 2 and is located in the placement groove 2a. The grille portion 11 and the hollow area 2b are directly opposite each other.

[0029] The panel assembly 100 of this utility model embodiment is used in the air conditioner 1000 and can play a role in supporting the structure of the air conditioner, protecting the internal structure of the air conditioner, and participating in defining the appearance of the air conditioner.

[0030] The panel assembly 100 includes a first panel 1 and a second panel 2. The second panel 2 is provided with a placement groove 2a. The first panel 1 is disposed on the side of the second panel 2 where the placement groove 2a is formed. The first panel 1 is located in the placement groove 2a. The first panel 1 and the second panel 2 are well connected, which can improve the structural stability and integrity of the panel assembly 100. Furthermore, the first panel 1 being located in the placement groove 2a can reduce the outward protrusion size, which is beneficial to reducing the size of the panel assembly 100.

[0031] The second panel 2 has a perforated area 2b communicating with the placement groove 2a. The perforated area 2b allows airflow to pass through. The first panel 1, located within the placement groove 2a, includes a grille portion 11, which faces the perforated area 2b. Airflow can pass through the perforated area 2b and the grille portion 11 and flow through the panel assembly 100. The grille portion 11 also acts as a shield for the perforated area 2b, preventing the user from extending their hand into the inside of the panel assembly 100 through the grille portion 11. This facilitates operations that require contact with the air conditioner, such as installation and subsequent maintenance, and helps reduce the impact on the internal structure of the air conditioner 1000 during operation.

[0032] For example, the panel assembly 100 can realize the air intake function. The airflow flows from the outside into the inside of the panel assembly 100 through the grille portion 11 and the hollow area 2b in sequence, and then flows to the heat exchanger inside the air conditioner. By utilizing the air intake of the panel assembly 100, compared with the design of the panel assembly as a solid panel, an air intake path can be added, thereby improving the functionality of the panel assembly 100. Moreover, when the air conditioner is provided with an air inlet, the addition of the air intake of the panel assembly 100 can increase the air intake volume of the air conditioner, which is beneficial to improving the heat exchange efficiency of the air conditioner.

[0033] For example, the panel assembly 100 can also provide airflow. The air from the air conditioner flows out of the panel assembly 100 through the perforated area 2b and the grille section 11 to regulate the indoor temperature. The grille section 11 can organize the airflow, reduce turbulence, and improve airflow stability. Furthermore, compared to a solid panel design, airflow through the panel assembly 100 provides an additional airflow path, increasing the airflow coverage of the air conditioner and improving its airflow performance.

[0034] As an example, there are multiple grille sections 11, and the panel assembly 100 can realize air intake and air outlet functions. The airflow flows into the panel assembly 100 from the outside through the grille section 11 and the hollow area 2b to intake air into the air conditioner. The air outlet of the air conditioner flows out of the panel assembly 100 through the hollow area 2b and the grille section 11 in sequence to regulate the indoor temperature. This not only improves the functionality of the panel assembly 100, but also helps to improve the working efficiency of the air conditioner.

[0035] According to the embodiment of the present utility model, the panel assembly 100 has a perforated area 2b formed on the second panel 2, and a grille portion 11 is provided on the first panel 1 located in the placement groove 2a of the second panel 2, which is directly opposite to the perforated area 2b. Airflow can pass through the panel assembly 100, and the panel assembly 100 can realize the functions of air intake and / or air exhaust, which can improve the functionality of the panel assembly 100 and help improve the ventilation and heat exchange efficiency of the air conditioner.

[0036] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the placement groove 2a includes a supporting bottom wall 21 and an annular placement peripheral wall 22; the first panel 1 is supported and fixed to the supporting bottom wall 21, and the placement peripheral wall 22 is arranged around the outer periphery of the first panel 1, and the placement peripheral wall 22 is formed as an inclined surface extending towards the supporting bottom wall 21.

[0037] The placement groove 2a includes a supporting bottom wall 21 and an annular placement peripheral wall 22. The annular placement peripheral wall 22 can be circular, rectangular, or other shapes, depending on the actual needs. Furthermore, "annular" is interpreted broadly; the placement peripheral wall 22 can be a complete ring with its ends connected; it can also be an incomplete ring, such as a ring with its ends spaced apart, or a rectangular ring with three connected sides; the placement peripheral wall 22 can also be multiple spaced segments forming an annular shape.

[0038] The first panel 1 is fixed to the supporting bottom wall 21, which supports and fixes the first panel 1, thereby improving the connection stability between the first panel 1 and the second panel 2.

[0039] The placement peripheral wall 22 is arranged around the outer periphery of the first panel 1, which improves the overall integrity of the panel assembly 100. Furthermore, the placement peripheral wall 22 is formed as a slope extending towards the supporting bottom wall 21, gradually sloping towards the first panel 1 in the concave direction of the placement groove 2a. This creates a gap between the placement peripheral wall 22 and the outer periphery of the first panel 1. The size of this gap gradually decreases in the concave direction of the placement groove 2a and is largest in the direction away from the second panel 2, i.e., largest in the outer direction of the panel assembly 100. This makes the first panel 1 appear separate from the second panel 2 from the outside, creating a floating visual effect and improving the appearance of the panel assembly 100.

[0040] In some embodiments of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, the second panel 2 also includes an outer wall 28, which is recessed inward to define at least a portion of the placement groove 2a. The outer surface of the outer wall 28 is substantially on the same plane as the outer surface of the first panel 1. The outer surface of the outer wall 28 and the outer surface of the first panel 1 may be on the same plane or on the same curved surface.

[0041] The outer side of the outer wall 28 is basically on the same plane as the outer side of the first panel 1, and the outer wall 28 is also separated from the outer periphery of the first panel 1. A placement periphery wall 22 is provided between the outer wall 28 and the outer periphery of the first panel 1, thereby further showing the visual separation effect of the first panel 1 and the second panel 2, and enhancing the floating visual effect of the first panel 1.

[0042] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the supporting bottom wall 21 is provided with a receiving plate 23 protruding towards the first panel 1, and the first panel 1 is provided with an upper abutting plate 13 protruding towards the second panel 2. The upper abutting plate 13 abuts against the top of the receiving plate 23.

[0043] The receiving plate 23 supports the upper abutment plate 13 from below, and the upper abutment plate 13 abuts against the top of the receiving plate 23, which can restrict the first panel 1 from moving downward under the action of gravity and improve the installation stability of the first panel 1 relative to the second panel 2.

[0044] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the first panel 1 is located on the front side of the second panel 2, with the groove 2a recessed towards the rear. The supporting bottom wall 21 is provided with a forward-protruding support plate 23. Correspondingly, the first panel 1 is located on a rearward-protruding upper abutment plate 13. The support plate 23 supports the upper abutment plate 13 from below, and the upper abutment plate 13 abuts against the upper part of the support plate 23, thereby restricting the downward movement of the first panel 1 relative to the second panel 2 and improving the installation stability of the first panel 1 relative to the second panel 2.

[0045] In some embodiments of this utility model, such as Figure 6 and Figure 20 As shown, the first panel 1 includes a plurality of grille sections 11, which include an air inlet grille 11a and an air outlet grille 11b.

[0046] The first panel 1 includes an air inlet grille 11a and an air outlet grille 11b. The panel assembly 100 can realize air inlet and air outlet functions, which not only improves the functionality of the panel assembly 100, but also helps to improve the working efficiency of the air conditioner.

[0047] Airflow passes sequentially through the air inlet grille 11a and the hollow area 2b and flows into the panel assembly 100 from the outside to supply air to the air conditioner. Compared with the design of the panel assembly as a solid panel, an additional air intake path can be added, thereby improving the functionality of the panel assembly 100. Furthermore, when the air conditioner is equipped with an air inlet, the addition of the panel assembly 100 for air intake can increase the air intake volume of the air conditioner, which is beneficial to improving the heat exchange efficiency of the air conditioner.

[0048] The air from the air conditioner flows through the perforated area 2b and the air outlet grille 11b before exiting the panel assembly 100 to regulate the indoor temperature. Compared to a solid panel design, this design allows for an additional air outlet path, increasing the air outlet coverage and improving the air outlet performance.

[0049] Furthermore, the first panel 1 includes multiple grille sections 11, including air inlet grille 11a and air outlet grille 11b. By setting multiple grille sections 11, the overall integrity of the panel assembly 100 can be improved, and the abruptness of setting grille sections 11 separately on the first panel 1 can be reduced.

[0050] The first panel 1 includes multiple grille sections 11, while the hollow area 2b on the second panel 2 can be a whole, with the grille sections 11 covering parts of the hollow area 2b respectively to achieve different functions; or, the hollow area 2b on the second panel 2 can be multiple, and each of the multiple grille sections 11 is set in a one-to-one correspondence.

[0051] In some embodiments of this utility model, such as Figure 6 and Figure 20 As shown, the first panel 1 includes a plurality of grille sections 11, each of which includes an air inlet grille 11a, an air outlet grille 11b, and a shielding grille 11c, with the shielding grille 11c connected between the air inlet grille 11a and the air outlet grille 11b.

[0052] The installation of the shielding grille 11c increases the distance between the air inlet grille 11a and the air outlet grille 11b, reducing the occurrence of air recirculation in the air conditioner and improving the air outlet heat exchange efficiency. Furthermore, the shielding grille 11c can also shield the structure located at the rear, providing protection. The grille 11c's grille-like design also enhances the overall integrity of the first panel 1 and improves the appearance of the panel assembly 100.

[0053] In some embodiments of this utility model, the first panel 1 and the second panel 2 are integral parts.

[0054] The first panel 1 and the second panel 2 are integrally molded parts, which can improve the overall integrity of the panel assembly 100 and enhance the structural stability of the panel assembly 100.

[0055] In some embodiments of this utility model, the first panel 1 and the second panel 2 are integral pieces, and the placement groove 2a includes a supporting bottom wall 21 and an annular placement peripheral wall 22. The first panel 1 is supported and fixed to the supporting bottom wall 21, and the placement peripheral wall 22 is arranged around the outer periphery of the first panel 1, forming an inclined surface extending towards the supporting bottom wall 21. This not only improves the overall integrity and structural stability of the panel assembly 100, but also allows the first panel 1 to be separated from the second panel 2 when viewed from the outside, creating a floating visual effect.

[0056] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the first panel 1 includes a panel portion 12 and a grille portion 11, and the grille portion 11 is fixedly engaged with at least one of the panel portion 12 and the second panel 2.

[0057] The first panel 1 includes a panel portion 12 and a grille portion 11. The panel portion 12 can shield the internal structure of the air conditioner on the inside, and the grille portion 11 is positioned opposite the hollow area 2b to allow airflow to pass through. The first panel 1 is designed to combine the solid panel portion 12 and the grille portion 11, which not only improves the structural stability of the first panel 1, but also enhances the functionality of the panel assembly 100.

[0058] The grille portion 11 can be fixedly engaged with the panel portion 12, the grille portion 11 can also be fixedly engaged with the second panel 2, and the grille portion 11 can also be fixedly engaged with both the panel portion 12 and the second panel 2.

[0059] The panel 12 can be assembled and connected to the second panel 2 after being separately formed. For example, the panel 12 and the second panel 2 can be fixedly connected by screws after positioning and fitting, which can improve the connection stability of the panel 12 and the second panel 2; or, as Figure 7 As shown, the panel portion 12 and the second panel 2 can also be integrally formed to improve the structural stability of the panel assembly 100, and the integrated structure formed by the grille portion 11 and the panel portion 12 and the second panel 2 is fixedly engaged.

[0060] In some embodiments of this utility model, such as Figure 1 As shown, the grille portion 11 is detachable from the panel portion 12 and the second panel 2.

[0061] By making the grille 11 detachable from the panel 12 and the second panel 2, the grille 11 can be removed separately when it needs to be cleaned, maintained, or replaced. This makes the removal operation convenient and reduces the difficulty of cleaning and maintaining the grille 11.

[0062] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the grille portion 11 is located below the panel portion 12. The upper part of the grille portion 11 is positioned and engaged with the panel portion 12 and the second panel 2, respectively, and the lower part of the grille portion 11 is positioned and engaged with the second panel 2.

[0063] The grille section 11 is positioned and fitted at both the top and bottom, which improves the stability of its arrangement. Furthermore, the grille section 11 is located below the panel section 12. Therefore, the upper part of the grille section 11 is positioned and fitted with the panel section 12 and the second panel 2, respectively, which improves the connection stability between the grille section 11, the panel section 12, and the second panel 2. The lower part of the grille section 11 does not have the structure of the panel section 12; it is simply positioned and fitted with the second panel 2.

[0064] In some embodiments of this utility model, such as Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the second panel 2 has a first protrusion 24 protruding forward, and the second panel 2 has a through hole 25 passing through the first protrusion 24 to divide the first protrusion 24 into an upper protrusion 241 and a lower protrusion 242. The rear side of the upper protrusion 241 has a hanging groove 26. The panel part 12 has a through hole 121, and the panel part 12 has a mating protrusion 122 located below the through hole 121. The mating protrusion 122 is located on the rear side of the lower protrusion 242 through the through hole 25. The upper end of the grille part 11 is provided with a first hook 111 that bends forward. The grille part 11 passes through the through hole 121 and the first hook 111 is hooked and engaged with the hanging groove 26 to restrict the grille part 11 from moving downward and forward relative to the panel part 12.

[0065] The first panel 1 is located on the front side of the second panel 2, and the groove 2a is recessed towards the rear. Here, the front-rear direction refers to the direction towards the working space of the air conditioner based on the air conditioner. The panel assembly 100 is located on the front side of the air conditioner and participates in defining the front appearance surface of the air conditioner.

[0066] The second panel 2 has a first protrusion 24 protruding forward. The first protrusion 24 has a through hole 25 in the middle of its vertical direction, which penetrates the second panel 2 in the front-back direction, thus dividing the first protrusion 24 into an upper protrusion 241 and a lower protrusion 242 spaced apart in the vertical direction. Both the upper protrusion 241 and the lower protrusion 242 protrude forward, thus protruding beyond the body of the second panel 2. Both the upper protrusion 241 and the lower protrusion 242 have a forward-protruding groove on their rear side, and the rear side of the upper protrusion 241 has a hanging groove 26.

[0067] The lower end of the panel 12 is provided with a mating protrusion 122. The mating protrusion 122 passes through the through hole 25 and is inserted into the rear side of the second panel 2. The mating protrusion 122 is located in the groove on the rear side of the lower protrusion 242. The mating protrusion 122 and the lower protrusion 242 are stably mated, which can improve the stability of the mating between the panel 12 and the second panel 2.

[0068] When assembling the panel 12 with the second panel 2, the panel 12 is moved downward relative to the second panel 2, and the mating protrusion 122 at the lower end of the panel 12 is inserted into the rear side of the second panel 2 through the through hole 25 and into the rear side of the lower protrusion 242, thereby positioning and mating the panel 12 and the second panel 2.

[0069] Furthermore, a through hole 121 is provided above the mating protrusion 122, which extends through the panel portion 12 in the front-back direction. When the mating protrusion 122 passes through the through hole 25 and is located on the rear side of the lower protrusion 242, the through hole 121 above the mating protrusion 122 is located in the area of ​​the through hole 25, and the through hole 121 and the through hole 25 are connected in the front-back direction.

[0070] The upper end of the grille section 11 is provided with a first hook 111 that bends forward. The first hook 111 at the upper end of the grille section 11 passes through the through hole 121 and the through hole 25 to the rear side of the second panel 2, thereby hooking and engaging with the hanging groove 26 on the rear side of the upper protrusion 241, thus positioning the grille section 11 and the second panel 2. Since the first hook 111 passes through the through hole 121 and the through hole 25 in sequence, the grille section 11 is positioned and engaged with both the panel section 12 and the second panel 2. The first hook 111 hangs on the bottom wall of the hanging groove 26, thereby restricting the downward movement of the grille section 11 relative to the panel section 12 and the second panel 2. Since the grille section 11 extends from the front side of the second panel 2 to the rear side of the second panel 2, the engagement of the first hook 111 with the hanging groove 26 also restricts the forward movement of the grille section 11, thereby improving the assembly stability of the grille section 11.

[0071] When assembling the grille portion 11 with the panel portion 12 and the second panel 2, the panel portion 12 and the second panel 2 are first assembled. Then, the grille portion 11 is tilted and moved backward from bottom to top, so that the first hook 111 at the upper end of the grille portion 11 tilts backward and passes through the through hole 121 and the through hole 25 in sequence, moving to the rear side of the upper protrusion 241. Next, the lower end of the grille portion 11 is swung backward, so that the first hook 111 at the upper end of the grille portion 11 swings forward and hooks into the hanging groove 26, thereby positioning the grille portion 11 with both the panel portion 12 and the second panel 2. Furthermore, since the first hook 111 passes through the through hole 121 and the through hole 25 in sequence, the assembly of the grille portion 11 also improves the stability of the fit between the panel portion 12 and the second panel 2.

[0072] By arranging the mating protrusion 122 and the through hole 121 adjacent to each other, when the mating protrusion 122 is located behind the lower protrusion 242 through the through hole 25, the through hole 121 above the mating protrusion 122 is located in the area of ​​the through hole 25, and the through hole 121 and the through hole 25 are connected in the front-rear direction. In this way, the grille part 11 can directly extend into the rear side of the second panel 2 through the through hole 121 and the through hole 25, without the need to provide additional holes on the second panel 2 for the grille part 11 to pass through, thereby reducing the manufacturing difficulty of the second panel 2. It also reduces the number of holes on the second panel 2, which is beneficial to improving the structural stability of the second panel 2.

[0073] In some embodiments of this utility model, such as Figure 8 and Figure 11 As shown, a second hook 112 is provided at the lower end of the grille section 11, and a locking pin 27 is provided on the second panel 2. The locking pin 27 is movably provided on the second panel 2 to engage or disengage with the second hook 112. When the locking pin 27 engages with the second hook 112, it positions the grille section 11.

[0074] The upper end of the grille section 11 has a first hook 111 that engages with the hanging groove 26, which restricts the grille section 11 from moving forward and downward. When the lower end of the grille section 11 is rotated forward at a preset angle, the engagement between the first hook 111 and the hanging groove 26 can be released, thereby allowing the grille section 11 to be removed.

[0075] Therefore, a detachment pin 27 that can move relative to the second panel 2 is provided on the second panel 2. When the detachment pin 27 engages with the second hook 112 at the lower end of the grille 11, the lower end of the grille 11 is positioned, and the lower end of the grille 11 cannot rotate forward. At this time, the freedom of the grille 11 is restricted, and the grille 11 is stably engaged with the panel 12 and the second panel 2, which can improve the arrangement stability of the grille 11. When it is necessary to disassemble the grille 11 relative to the panel 12 and the second panel 2, it is only necessary to drive the detachment pin 27 to move and cancel the engagement between the detachment pin 27 and the second hook 112, so that the lower end of the grille 11 can be rotated forward by a preset angle, and then the grille 11 can be disassembled.

[0076] In some embodiments of this utility model, such as Figure 11 As shown, the second hook 112 is located at the lower end of the grille section 11 and extends backward and upward. The anti-detachment pin 27 is movable up and down and engages with the second panel 2. When the anti-detachment pin 27 moves downward and stops in front of the second hook 112, it restricts the lower end of the grille section 11 from rotating forward. When the anti-detachment pin 27 moves upward and disengages from the second hook 112, the lower end of the grille section 11 can rotate forward relative to the second panel 2.

[0077] The anti-detachment pin 27 can be stabilized in the position that engages with the second hook 112 under the action of gravity, reducing the possibility of the anti-detachment pin 27 being accidentally separated from the second hook 112 due to force impact.

[0078] In some embodiments of this utility model, such as Figure 8 As shown, the mesh section 11 has a second hook 112, and the mating part is a solid structure located on the front side of the second panel 2 to cover part of the second panel 2.

[0079] The first part 113 is the mating portion of the grille section 11 with the second hook 112. The first part 113 is used for positioning and mating with the second panel 2. The first part 113 is designed as a solid structure to cover the second panel 2, which can prevent airflow from passing through the first part 113, thereby reducing the impact of the flowing airflow on the second hook 112 and the anti-detachment pin 27, improving the stability of the positioning and mating between the grille section 11 and the second panel 2, and protecting the structure of the second panel 2 located at the rear. Although the first part 113 is a solid structure, it still has a grille structure. The grille structure of the first part 113 is integrally formed with the grille structure of the part through which the airflow passes, thereby improving the overall integrity of the grille section 11.

[0080] In some embodiments of this utility model, such as Figure 1 and Figure 8 As shown, second hooks 112 are provided on the left and right sides of the grille section 11. Since the air duct of the air conditioner does not extend to the left and right sides of the grille section 11 in the left-right direction, designing the left and right ends of the grille section 11 as solid structures has little impact on the airflow of the air conditioner. Furthermore, designing the left and right ends of the grille section 11 as solid structures can reduce the amount of airflow escaping into the spaces on the left and right sides of the grille section 11, thereby reducing condensation on the left and right sides of the grille section 11.

[0081] like Figure 10 and Figure 11 As shown, the anti-detachment pin 27 is located on the rear side of the second panel 2, making it difficult to directly drive the anti-detachment pin 27 from the front. Therefore, in some embodiments of this utility model, such as Figure 12 As shown, the panel assembly 100 can be flipped open relative to other structures of the air conditioner indoor unit 1000, thereby facilitating the operation of the anti-detachment pin 27.

[0082] In some embodiments of this utility model, such as Figures 13-15 As shown, the second panel 2 has a sliding structure 29 that slides and engages with the anti-detachment pin 27. The sliding structure 29 has a sliding groove 293, and the anti-detachment pin 27 has a sliding engagement portion 272. The sliding engagement portion 272 is slidably disposed in the sliding groove 293 so that the anti-detachment pin 27 can move up and down relative to the engagement portion 22.

[0083] The sliding structure 29 is provided with a first limiting part 291 and a second limiting part 292 at intervals along the sliding direction of the anti-detachment pin 27. In this way, when the anti-detachment pin 27 slides to the position of the first limiting structure 31, the anti-detachment pin 27 is limited and engaged with the first limiting part 291, and the anti-detachment pin 27 is stably engaged with the second hook 112; when the anti-detachment pin 27 slides to the position of the second limiting structure 121, the anti-detachment pin 27 is disengaged from the first limiting structure 31 and is limited and engaged with the second limiting structure 121, and the anti-detachment pin 27 is stabilized in the position where it is disengaged from the second hook 112.

[0084] When the anti-disengagement pin 27 slides along the sliding structure 29, it can cooperate with the first limiting part 291 or the second limiting part 292. The movement of the anti-disengagement pin 27 is simple, reliable and easy to operate.

[0085] In some embodiments of this utility model, such as Figures 13-15 As shown, the anti-detachment pin 27 has an elastic buckle 271, and the first limiting part 291 and the second limiting part 292 are respectively formed as slots. The elastic buckle 271 is adapted to be limited and engaged in the slot.

[0086] The anti-disengagement pin 27 has an elastic buckle 271, which can elastically deform. When the anti-disengagement pin 27 slides to the position of the first limiting part 291, the elastic buckle 271 is fixed in the slot in its original state, and the anti-disengagement pin 27 can no longer slide, thereby limiting the anti-disengagement pin 27 to the first limiting part 291.

[0087] Simply by driving the elastic buckle 271 to generate elastic deformation and moving the elastic buckle 271 out of the slot, the limiting engagement between the anti-detachment pin 27 and the first limiting part 291 can be released, and the anti-detachment pin 27 can continue to slide.

[0088] Similarly, when the anti-disengagement pin 27 slides to the position of the second limiting part 292, the elastic buckle 271 is in the original limiting engagement in the slot, and the anti-disengagement pin 27 is in the limiting engagement with the second limiting part 292.

[0089] The anti-detachment pin 27 forms an elastic buckle 271 that engages with the slot. During the movement of the anti-detachment pin 27, it can automatically complete the limiting engagement by utilizing its own elastic properties. It does not require manual driving to deform, making it convenient to use and easy to operate.

[0090] In some embodiments of this utility model, such as Figure 10 As shown, a guide groove 294 communicating with the slide groove 293 is formed on the peripheral side wall of the slide groove 293. The anti-disengagement pin 27 has a guide portion 273, a sliding engagement portion 272 slidingly engages with the slide groove 293, and a guide portion 273 slidingly engages with the guide groove 294.

[0091] A guide groove 294 communicating with the slide groove 293 is also formed on the peripheral wall of the slide groove 293. The anti-disengagement pin 27 also has a guide part 273, which slides and cooperates with the guide groove 294 to further limit the movement of the anti-disengagement pin 27. The guide groove 294 is provided on the peripheral wall of the slide groove 293. The cooperation between the guide groove 294 and the guide part 273 can also reduce the swaying of the anti-disengagement pin 27 in the width direction of the guide groove 294 and improve the movement stability of the anti-disengagement pin 27 relative to the sliding structure 29.

[0092] In some embodiments of this utility model, such as Figure 13 As shown, a guide groove 294 is provided on the rear side wall of the slide groove 293. The guide part 273 is connected to the sliding engagement part 272. At least a part of the guide part 273 passes through the guide groove 294, which can further limit the sliding of the anti-disengagement pin 27 and improve the movement stability of the anti-disengagement pin 27.

[0093] In some embodiments of this utility model, such as Figure 13 As shown, the locking pin 27 also has an operating part 274, which is connected to one end of the guide part 273 away from the sliding mating part 272 and located outside the slide groove 293. The operating part 274 is configured such that operating the operating part 274 can move the locking pin 27 between the locked state and the unlocked state.

[0094] The operating part 274 is located outside the slide groove 293, which facilitates direct operation of the operating part 274 from the outside, improving ease of use.

[0095] In some embodiments of this utility model, such as Figure 13 As shown, the operating part 274 is provided with a plurality of raised ribs at intervals, which can increase the surface friction of the operating part 274 and facilitate the operation of the operating part 274.

[0096] The air conditioner 1000 of the second aspect of this utility model is described below with reference to the accompanying drawings.

[0097] According to an embodiment of the present utility model, the air conditioner 1000, such as Figure 16 and Figure 17 As shown, the air conditioner 1000 includes: a front frame 200 and a panel assembly 100, the panel assembly 100 being the panel assembly 100 according to the first aspect of the present invention, and a second panel 2 being mounted to the front frame 200.

[0098] According to the embodiment of the present utility model, the air conditioner 1000, by setting the panel assembly 100 of the first aspect of the present utility model, not only can the panel assembly 100 perform the functions of air intake and / or air exhaust, thereby improving the working efficiency of the air conditioner 1000, but the panel assembly 100 also participates in defining the front appearance of the air conditioner 1000, and the first panel 1 of the panel assembly 100 also creates a floating visual effect.

[0099] In some embodiments of this utility model, such as Figure 18 As shown, the air conditioner 1000 also includes an air outlet 201 located at the bottom of the face frame 200 and an air guide plate 3 for opening or closing the air outlet 201; when the air guide plate 3 closes the air outlet 201, the air guide plate 3 cooperates with the bottom of the grille portion 11.

[0100] The bottom of the face frame 200 has an air outlet 201. When the grille section 11 is discharging air, the air conditioner 1000 can choose to discharge air through the air outlet 201 at the bottom of the face frame 200, or the air conditioner 1000 can choose to discharge air through the grille section 11 on the front side of the face frame 200, which can improve the air outlet coverage of the air conditioner 1000.

[0101] When the air guide plate 3 closes the air outlet 201, the air guide plate 3 cooperates with the bottom of the grille section 11, that is, the bottom of the grille section 11 participates in limiting the air outlet 201.

[0102] An air outlet 201 is formed on the bottom side of the face frame 200. The air guide plate 3 can open or close the air outlet 201 to control the flow of air. Not limited to this, the air guide plate 3 can also guide the airflow after opening the air outlet 201. For example, the air guide plate 3 can guide the airflow forward, increasing the forward transport distance of the airflow. When the grille section 11 discharges air, the forward-guided airflow can lift the air outlet from the grille section 11, thereby increasing the forward flow distance of the airflow. Another example is that the air guide plate 3 can guide the airflow downward, pressing down the air outlet 201 located on the bottom side of the face frame 200. This is beneficial for heating airflow, delivering hot air to the foot area. The hot air diffuses and heats up from bottom to top, greatly improving the heating effect and making the stratification more uniform.

[0103] In some embodiments of this utility model, such as Figure 18 As shown, a guide slope 31 is formed on the front side of the air guide plate 3, and the guide slope 31 extends obliquely in a direction away from the grille portion 11.

[0104] When the air guide plate 3 closes the air outlet 201, the air guide plate 3 cooperates with the bottom of the grille section 11, that is, the bottom of the grille section 11 participates in defining the air outlet 201. Therefore, there is no second panel 2 at the bottom of the grille section 11, and the second panel 2 only surrounds the left, right and top sides of the first panel 1.

[0105] An air guide slope 31 is formed on the front side of the air guide plate 3. The air guide slope 31 extends obliquely away from the grille part 11. The air guide slope 31 and the slope formed by the placement peripheral wall 22 together form a complete ring around the first panel 1, thereby creating a floating visual effect for the first panel 1.

[0106] In other embodiments of this utility model, such as Figure 6 and Figure 20As shown, the second panel 2 surrounds the left, right, upper and lower sides of the first panel 1, and also has a placement perimeter wall 22 at the bottom of the grille section 11, so that the first panel 1 creates a floating visual effect relative to the second panel 2.

[0107] The bottom of the faceplate 200 is provided with an air outlet 201, and an air guide plate 3 is provided at the air outlet 201 to open and close the air outlet 201. When the air guide plate 3 closes the air outlet 201, the air guide plate 3 cooperates with the bottom of the second panel 2.

[0108] In some embodiments of this utility model, such as Figure 6 and Figure 19 As shown, the air conditioner 1000 includes a display box 4, which is arranged in the left-right direction with the first panel 1. The second panel 2 surrounds the upper side of the first panel 1 and the display box 4, and also surrounds the side of the first panel 1 and the display box 4 that is far away from each other in the left-right direction.

[0109] The display box 4 can display the operating information of the air conditioner 1000, or information such as indoor and outdoor temperatures, which can display the information intuitively and improve the functionality of the air conditioner 1000.

[0110] The display box 4 and the first panel 1 are arranged in the left-right direction. The second panel 2 surrounds the upper side of the first panel 1 and the display box 4. The second panel 2 also surrounds the side of the first panel 1 and the display box 4 that is far away from each other in the left-right direction, so that the first panel 1 and the display box 4 create a floating visual effect, making the information on the display box 4 more obvious.

[0111] In some embodiments of this utility model, the display box 4, the first panel 1, and the second panel 2 are fixedly connected by fasteners. The fasteners connect the adjacent sides of the display box 4 and the first panel 1, and then the fasteners continue to fix the second panel 2 together. By fixing three parts together with one fastener, the assembly efficiency can be improved.
