[0086] In some embodiments of the utility model, as shown in Figure 2 and Figure 4 As shown, the panel part 1 comprises a mounting plate 12, the mounting plate 12 comprises a recessed groove 121 recessed from front to back, the rear groove surface of the recessed groove 121 is an annular ring 1211, the annular ring 1211 defines an annular hole 1212, the knob part 111 is embedded in the recessed groove 121 from front to back, and the gear ring part 1131 is separately arranged at the front side and the rear side of the mounting plate 12, the annular ring 1211 supports the edge of the knob part 111, and the gear ring 11312 is located at the rear side of the mounting plate 12 and connected with the knob part 111 through the annular hole 1212.

[0087] The mounting plate 12 is provided with a recessed groove 121 recessed from front to back, and the knob part 111 is embedded in the recessed groove 121, so as to reduce the size of the knob part 111 protruding from the front of the panel component 1, reduce the interference with the outside world, and improve the integrity of the air conditioner 100. The rear groove surface of the recessed groove 121 is an annular ring 1211, which bears the knob part 111 in the circumferential direction, so as to improve the assembly stability of the knob part 111.

[0088] The annular ring 1211 defines an annular hole 1212, through which the fastener 1135 and the buckle 1111 pass, so as to connect the gear ring part 1131 and the knob part 111 arranged on the front and back sides of the mounting plate 12.

[0089] In some embodiments of the utility model, as shown in Figure 2 、 Figure 3 and Figure 4 , the panel component 1 comprises a mounting plate 12, the mounting plate 12 comprises a first plate 122 and a second plate 123, the second plate 123 protrudes forwardly from the first plate 122, the first plate 122 is connected with the second plate 123 through a stepped plate 124, the stepped plate 124 is formed with a avoiding hole 1241, the end of the air outlet grille 2 is located on the front side of the first plate 122, the gear ring part 1131 and the gear condition 1132 are arranged on the rear side of the second plate 123, the limiting part 112 is opposite to the avoiding hole 1241, and the limiting part 112 extends to the front side of the first plate 122 from the avoiding hole 1241 in the limiting position to limit the air outlet grille 2.

[0090] The gear ring part 1131 and the gear condition 1132 are located on the rear side of the mounting plate 12, and the limiting part 112 in transmission cooperation with the gear ring part 1131 is also at least partially located on the rear side of the mounting plate 12, which can improve the transmission stability of the linkage mechanism 113 and the limiting part 112 on the one hand, and protect the limiting part 112 and improve the working reliability of the limiting part 112 on the other hand.

[0091] The air outlet grille 2 is located on the front side of the mounting plate 12, therefore, the mounting plate 12 is arranged as a stepped structure, the avoiding hole 1241 is formed on the stepped plate 124 between the first plate 122 and the second plate 123, the limiting part 112 is opposite to the avoiding hole 1241, the limiting part 112 extends to the front side of the first plate 122 from the avoiding hole 1241 in the limiting position to limit the air outlet grille 2, so as to limit the air outlet grille 2 from being disassembled forwardly relative to the panel component 1; the limiting part 112 is retracted to the rear side of the second plate 123 from the avoiding hole 1241 in the avoiding position, so as to avoid the disassembly path of the air outlet grille 2, and the limiting part 112 is retracted to the rear side of the second plate 123 from the avoiding hole 1241 in the avoiding position, so as to avoid the disassembly path of the air outlet grille 2.

[0092] In some other embodiments of this utility model, the locking device 11 further includes a guide rail structure 114, which is guided and cooperates with the limiting member 112 to limit the translation direction F1 of the limiting member 112. The linkage mechanism 113 includes a winding device and a return spring. The return spring is used to drive the limiting member 112 to translate toward the limiting position. The winding device rotates with the knob 111 and pulls the limiting member 112 to overcome the elastic force of the return spring to translate toward the avoidance position when winding up the cable.

[0093] By setting the guide rail structure 114, the limiting member 112 can be guided, improving the smoothness of the translational movement of the limiting member 112 between the limiting position and the avoidance position. Furthermore, the guide rail structure 114 limits the translational path of the limiting member 112, so that the limiting member 112 moves stably along the translational direction F2 perpendicular to the tooth condition 1132, thereby improving the movement stability of the limiting member 112.

[0094] The linkage mechanism 113 includes a reel and a return spring. The return spring drives the limiting member 112 to translate towards the limiting position. When the limiting member 112 is in the limiting position, the return spring is in its normal state, so that the limiting member 112 is normally in the limiting position. The locking device 11 is normally in the locked state, limiting the air outlet grille 2, which can improve the working stability of the limiting member 112. When the knob 111 is rotated and the cable is retracted, the limiting member 112 is pulled to overcome the elastic force of the return spring and translate towards the avoidance position, thereby driving the limiting member 112 to move from the limiting position to the avoidance position, which can release the limitation on the air outlet grille 2 and allow the air outlet grille 2 to be disassembled.

[0095] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, one end of the air outlet grille 2 in the length direction has a first mounting portion 21. The panel component 1 is provided with a first mating portion 1b corresponding to the first mounting portion 21. The first mating portion 1b includes a locking device 11. The first mounting portion 21 has a stop portion 213. The limiting member 112 moves in a direction away from the knob member 111 and close to the air outlet grille 2 to reach the limiting position. In the limiting position, the limiting member 112 stops the stop portion 213 from moving forward.

[0096] The locking device 11 is positioned at the end of the air outlet grille 2 along its length to lock it in place. When the limiting member 112 is in the limiting position, i.e., when the locking device 11 is locked, the limiting member 112 stops at the front side of the mating part of the air outlet grille 2, thereby restricting the air outlet grille 2 from being disassembled forward relative to the panel component 1. When the limiting member 112 is in the avoidance position, i.e., when the locking device 11 is unlocked, the limiting member 112 avoids the disassembly path of the air outlet grille 2, thus releasing the restriction on the air outlet grille 2.

[0097] like Figure 3As shown, the first mounting portion 21 has a stop portion 213, the limiting piece 112 is arranged at the first matching portion 1b, and after the limiting piece 112 moves from the limiting position to the avoiding position, the first mounting portion 21 of the air outlet grille 2 can be pulled out forward, thereby facilitating the quick disassembly of the air outlet grille 2, and the design of the quick disassembly scheme is simpler.

[0098] The limiting piece 112 is translated towards the direction away from the knob piece 111 and close to the air outlet grille 2 to reach the limiting position, and the limiting piece 112 is translated towards the direction away from the air outlet grille 2 and close to the knob piece 111 to reach the avoiding position. In this way, the movement direction of the limiting piece 112 is substantially parallel to the air outlet grille 2, rather than perpendicular to the air outlet grille 2, so that the space required for the movement of the limiting piece 112 can be reduced. Of course, when the space allows, the movement along the direction perpendicular to the air outlet grille 2 (for example, along the front-rear direction) can also be arranged.

[0099] In some embodiments of the present application, as shown in Figure 9 and Figure 10 As shown, the first mounting portion 21 includes a limiting portion 211, and the limiting portion 211 defines a limiting slot 2111 open towards the direction of the limiting piece 112, as shown in Figure 5 As shown, the limiting piece 112 extends into the limiting slot 2111 at the limiting position, and the limiting piece 112 exits from the limiting slot 2111 at the avoiding position.

[0100] The extension of the limiting piece 112 into the limiting slot 2111 can limit the forward movement of the first mounting portion 21, and the exit of the limiting piece 112 from the limiting slot 2111 can pull the first mounting portion 21 forward, thereby facilitating the quick disassembly of the air outlet grille 2, and the design of the quick disassembly scheme is simpler. As shown in Figure 3 As shown, the rear slot surface of the limiting slot 2111 is configured as a stop portion 213, and the limiting piece is stopped at the front side of the rear slot surface of the limiting slot 2111 to stop the forward movement of the limiting portion 211.

[0101] And when the limiting piece 112 extends into the limiting slot 2111 for limiting, the limiting piece 112 is not exposed, the limiting piece 112 can be protected, and the working reliability of the limiting piece 112 and the integrity of the air conditioner 100 are improved.

[0102] In some embodiments of the present application, the size of the limiting piece 112 extending into the limiting slot 2111 is 11.5mm-14.5mm.

[0103] In some embodiments of the present application, as shown in Figure 11 and Figure 12As shown, the locking device 11 further comprises a guide rail structure 114 in guided cooperation with the limiting piece 112 to limit the translation direction F1 of the limiting piece 112, the guide rail structure 114 comprises a first guide rail part 1141 extending along the radial direction of the knob piece 111, the limiting piece 112 comprises a guide part 1122 and a locking pin part 1123, the guide part 1122 is in sliding cooperation with the first guide rail part 1141, and the locking pin part 1123 is arranged on both sides of the guide part 1122. Figure 10 and Figure 5 As shown, the limiting part 211 is two and is arranged in a spaced manner to form an avoiding groove 212 between the two limiting parts 211, and the two locking pin parts 1123 are arranged in correspondence with the two limiting parts 211 respectively, and the guide part 1122 is arranged in correspondence with the avoiding groove 212.

[0104] The guide part 1122 is used for guiding, and the locking pin part 1123 is used for limiting the forward movement of the first mounting part 21, and by arranging the locking pin part 1123 on both sides of the guide part 1122, the cooperation stability of the limiting piece 112 and the limiting part 211 can be improved, thereby improving the limiting effect of the limiting piece 112.

[0105] As shown in Figure 3 and Figure 5 The limiting part 211 protrudes rearward, the avoiding groove 212 is formed on the rear side of the air outlet grille 2, and the guide part 1122 will not be exposed when being inserted into the avoiding groove 212, thereby protecting the guide part 1122.

[0106] In some embodiments of the utility model, as shown in Figure 1 and Figure 2 The length direction of the air outlet grille 2 is the upward and downward direction, and the knob piece 111 is located below the air outlet grille 2, as shown in Figure 11 and Figure 12 The limiting piece 112 is located above the knob piece 111, and the knob piece 111 drives the limiting piece 112 to be translatable along the upward and downward direction through the linkage mechanism 113.

[0107] By arranging the knob piece 111 at the lower end of the air outlet grille 2, the height of the knob piece 111 is relatively low, thereby facilitating operation. The length direction of the air outlet grille 2 is the upward and downward direction, so that the movement space in the upward and downward direction is relatively large, and by arranging the limiting piece 112 to be translatable along the upward and downward direction, the movement and arrangement of the limiting piece 112 are facilitated.

[0108] In some embodiments of the utility model, as shown in Figure 11 and Figure 12As shown, the knob piece 111 includes a knob piece handle 1112 extending along the diameter direction of the knob piece 111, and the knob piece handle 1112 is provided with a direction indicating structure 1113, the knob piece 111 can rotate at least 180°, and is switched to the locking state when the direction indicating structure 1113 is rotated upward, and is switched to the unlocking state when the direction indicating structure 1113 is rotated downward.

[0109] By arranging the direction indicating structure on the knob handle piece, the indication is obvious, which is convenient for determining whether to unlock or lock, and is convenient to use.

[0110] In some embodiments of the utility model, as shown in Figure 11 and Figure 12 As shown, the direction indicating structure 1113 on the knob piece 111 is configured as an arrow, the arrow points upward, indicating that the locking device 11 is switched to the locking state, and the arrow points downward, indicating that the locking device 11 is switched to the unlocking state.

[0111] In some embodiments of the utility model, as shown in Figure 1 and Figure 8 As shown, the other end of the length direction of the air outlet grille 2 is provided with a second mounting portion 22, and the panel member 1 is provided with a second matching portion 1c corresponding to the second mounting portion 22; wherein the second mounting portion 22 is inserted and matched with the second matching portion 1c by moving the air outlet grille 2 relative to the panel member 1 along the direction from the first matching portion 1b to the second matching portion 1c.

[0112] The two ends of the length direction of the air outlet grille 2 are matched with the panel member 1 respectively, which can improve the assembly stability of the air outlet grille 2 relative to the panel member 1. The assembly process of the air outlet grille 2 and the panel member 1 is that the second mounting portion 22 is inserted and matched with the second matching portion 1c first, and then the first mounting portion 21 is assembled with the first matching portion 1b, and the first matching portion 1b limits the forward movement of the first mounting portion 21.

[0113] The first mounting portion 21 is assembled with the first matching portion 1b, and the second mounting portion 22 is inserted and matched with the second matching portion 1c, so as to limit the movement of the length direction of the air outlet grille 2, and the second matching portion 1c and the first matching portion 1b both limit the movement of the air outlet grille 2 in the front and rear directions, thereby improving the assembly stability of the air outlet grille 2.

[0114] In other embodiments of the utility model, the second mounting portion 22 is snap-fitted with the second matching portion 1c by pressing the air outlet grille 2 relative to the panel member 1 from front to back.

[0115] The second mounting portion 22 is snap-fitted with the second matching portion 1c by pressing the air outlet grille 2 relative to the panel member 1 from front to back, which is simple and stable in cooperation and convenient to operate.

[0116] In some embodiments of this utility model, such as Figure 9 and Figure 14 As shown, the air outlet grille 2 includes a grille body 23. The grille body 23 has a rearward protruding limiting structure 231 in the middle of its length direction. A crossbeam 13 extending along the width direction of the air outlet grille 2 and opposite to the limiting structure 231 is provided at the air outlet frame opening 1a. The crossbeam 13 has a third mating structure 131.

[0117] The two ends of the air vent grille 2 along its length are respectively assembled with the panel component 1, and the middle part of the air vent grille 2 along its length is also assembled with the panel component 1, further improving the assembly stability of the air vent grille 2. It can also reduce the occurrence of the middle protrusion of the air vent grille 2, reduce the gap between the air vent grille 2 and the panel component 1, and improve the overall integrity.

[0118] Optionally, the limiting structure 231 engages with the third mating structure 131 by moving the air outlet grille 2 relative to the panel component 1 from front to back, thereby restricting the movement of the air outlet grille 2 relative to the panel component 1 along the width direction of the air outlet grille 2.

[0119] When the air vent grille 2 is assembled onto the panel component 1, it moves from front to back relative to the panel component 1. By designing the limiting structure 231 and the third mating structure 131 to move inward and engage, the engagement can be completed smoothly during the assembly of the air vent grille 2, reducing the difficulty of the assembly operation. Furthermore, the engagement also restricts the movement of the air vent grille 2 relative to the panel component 1 along the width direction of the air vent grille 2, reducing the swaying of the air vent grille 2 and improving the assembly stability of the air vent grille 2.

[0120] Or, such as Figure 15 As shown, the limiting structure 231 allows the air outlet grille 2 to move relative to the panel component 1 along the direction from the first mating part 1b to the second mating part 1c to engage with the third mating structure 131, thereby limiting the relative movement of the air outlet grille 2 and the panel component 1 in the front-to-back direction and improving the assembly stability of the air outlet grille 2.

[0121] For example, when the second mounting part 22 moves along the direction from the first mating part 1b to the second mating part 1c through the air outlet grille 2 relative to the panel component 1 to engage with the second mating part 1c, the limiting structure 231 can also simultaneously engage with the third mating structure 131, simplifying the assembly steps and reducing the difficulty of assembly operations.

[0122] In some embodiments of this invention, the air outlet grille 2 and the panel component 1 are connected by hand without screws. The disassembly and assembly of the air outlet grille 2 is simple, making it easy to clean.

[0123] In some embodiments of this utility model, such as Figure 1As shown, the air conditioner 100 further comprises a shielding panel 3, which is detachably mounted on the front side of the panel component 1 and shields the locking device 11.

[0124] The shielding panel 3 is mounted on the front side of the panel component 1 and shields the locking device 11, which can improve the integrity of the air conditioner 100 and protect the rear locking device 11 from being unlocked by mistake.

[0125] In some embodiments of the present application, the rear side of the shielding panel 3 protrudes with an interference part 31, which is oppositely arranged relative to the knob part 111 and is offset from the center of the knob part 111. The knob part 111 is formed with a clearance zone, and when the locking device 11 is in the unlocked state, the knob part 111 interferes with the interference part 31. When the locking device 11 is in the locked state, the clearance zone avoids the interference part 31.

[0126] When the locking device 11 is in the unlocked state, the knob part 111 interferes with the interference part 31, and the shielding panel 3 cannot be assembled with the panel component 1, which can serve as a reminder and prevent the shielding panel 3 from being assembled to the front side of the panel component 1 to shield the locking device 11 when the locking device 11 is still in the unlocked state. When the locking device 11 is in the locked state, the knob part 111 avoids the interference part 31, and the shielding panel 3 can be directly mounted to the front side of the panel component 1 to shield and protect the locking device 11.

[0127] In some embodiments of the present application, as shown in Figure 1 and Figure 8 The shielding panel 3 is located below the air outlet grille 2, the upper end of the shielding panel 3 shields the front side of the lower end of the air outlet grille 2, and the upper end of the shielding panel 3 is limitedly matched with the lower end of the air outlet grille 2 to limit the relative movement of the shielding panel 3 and the air outlet grille 2 in the up-down direction.

[0128] The upper end of the shielding panel 3 shields the front side of the lower end of the air outlet grille 2 and is limitedly matched with the lower end of the air outlet grille 2, which can limit the relative movement of the shielding panel 3 and the air outlet grille 2 in the up-down direction. This design also allows the shielding panel 3 and the air outlet grille 2 to move together in the up-down direction, thereby ensuring the design gap between the shielding panel 3 and the air outlet grille 2.

[0129] And the upper end of the shielding panel 3 is limitedly matched with the lower end of the air outlet grille 2, which can effectively limit the grille when the locking device 11 fails, preventing the grille from coming loose during transportation.

[0130] In some embodiments of the present application, as shown in Figure 16 The lower end of the shielding panel 3 is hooked to the panel component 1 through the downwardly extending hook structure 32.

[0131] When the shielding panel 3 is driven upward by the air outlet grille 2, the hook structure 32 can also be kept in hooking cooperation with the panel component 1, improving the cooperation stability of the shielding panel 3, the air outlet grille 2 and the panel component 1.

[0132] In some embodiments of the present application, as shown in Figure 8 The left and right sides of the shielding panel 3 are in clamping cooperation with the panel component 1 through the rearwardly extending clamping structure 33, so as to limit the forward movement of the shielding panel 3 relative to the panel component 1, and improve the assembly stability of the shielding panel 3 and the panel component 1.

[0133] The disassembly process of the air outlet grille 2 of the air conditioner 100 in one specific embodiment of the present application will be described below with reference to the accompanying drawings.

[0134] The length direction of the air outlet grille 2 is the up-down direction, the top of the air outlet grille 2 is in plug-in cooperation with the panel component 1 from bottom to top, the middle position of the length direction of the air outlet grille 2 is in plug-in cooperation with the panel component 1 from bottom to top, and the locking device 11 is located below the air outlet grille 2 and is used to limit the outward movement of the bottom of the air outlet grille 2.

[0135] The locking device 11 comprises a knob piece 111, a limiting piece 112 and a linkage mechanism 113, the knob piece 111 drives the limiting piece 112 to move in translation between a limiting position and a avoiding position through the linkage mechanism 113, the limiting piece 112 moves upward when moving to the limiting position, and the limiting piece 112 moves downward when moving to the avoiding position.

[0136] The linkage mechanism 113 comprises a gear ring piece 1131 and a gear condition 1132, the gear ring piece 1131 is coaxially arranged with the knob piece 111 and connected with the knob piece 111 to rotate synchronously with the knob piece 111, the gear condition 1132 is arranged on the outer peripheral region of the gear ring piece 1131, and the gear ring piece 1131 is engaged to move in translation along the tangential direction of the gear ring piece 1131.

[0137] The gear condition 1132 has a driving wedge surface 11321 thereon, and the side surface of the limiting piece 112 facing the driving wedge surface 11321 is configured as a matching wedge surface 1121. The driving wedge surface 11321 on the gear condition 1132 extends downwardly and obliquely from left to right, and correspondingly, the matching wedge surface 1121 on the limiting piece 112 also extends downwardly and obliquely from left to right, the movement of the gear condition 1132 in translation to the right drives the limiting piece 112 to move upward, i.e. from the avoiding position to the limiting position, and the movement of the gear condition 1132 in translation to the left drives the limiting piece 112 to move downward, i.e. from the limiting position to the avoiding position.

[0138] In the assembly process, the upper end of the air outlet grille 2 is inserted into the panel component 1 from bottom to top, the panel component 1 limits the forward movement of the upper end of the air outlet grille 2, then the middle part of the air outlet grille 2 is inserted into the panel component 1 from bottom to top, and finally the lower end of the air outlet grille 2 is matched with the panel component 1 and the locking device 11. Figure 6 and Figure 11 As shown in the figure, from the rear to the front direction, the driving knob part 111 is rotated clockwise, the arrow on the knob part 111 is rotated to point upward, the limiting part 112 is pushed upward to the front side of the bottom of the air outlet grille 2, and the bottom of the air outlet grille 2 is limited to be disassembled forward. The panel component 1 supports the air outlet grille 2 to limit the air outlet grille 2 from falling downward, and the locking device 11 limits the bottom of the air outlet grille 2 to move forward, so that the air outlet grille 2 is assembled on the panel component 1.

[0139] In the disassembly process, the whole sequence is reversed, first, the locking device 11 is disengaged from the limiting of the air outlet grille 2. Figure 7 Figure 12 As shown in the figure, from the rear to the front direction, the driving knob part 111 is rotated counterclockwise, the arrow on the knob part 111 is rotated to point downward, the limiting part 112 is driven downward to the lower side of the bottom of the air outlet grille 2, and the bottom of the air outlet grille 2 is disengaged from the limiting. Then the bottom of the air outlet grille 2 is pulled outward, so that the air outlet grille 2 can move downward relative to the panel component 1, and finally the air outlet grille 2 is disassembled from the panel component 1 from top to bottom.
