[0058] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0060] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0061] According to the embodiment of the present utility model, the air conditioner 100, such as Figures 1-3 As shown, the air conditioner 100 includes: a panel component 1 and an air outlet grille 2. The front side of the panel component 1 has an air outlet frame 1a. The panel component 1 has a first insertion structure 11 at the top of the air outlet frame 1a. The air outlet grille 2 covers the air outlet frame 1a. The upper end of the air outlet grille 2 has a second insertion structure 21, which is adapted to engage with the first insertion structure 11 from bottom to top to prevent the upper end of the air outlet grille 2 from dislodging forward relative to the panel component 1. The panel component 1 has a locking mechanism 12 at the bottom of the air outlet frame 1a. The locking mechanism 12 switches between a locked state and an unlocked state, such as... Figure 2 As shown, in the locked state, the locking mechanism 12 lifts the air outlet grille 2 so that the second insertion structure 21 and the first insertion structure 11 remain engaged, as shown. Figure 3 As shown, in the unlocked state, the locking mechanism 12 removes the lifting of the air outlet grille 2, so that the second plug-in structure 21 can disengage downward from its engagement with the first plug-in structure 11.

[0062] The panel component 1 is located on the front side of the air conditioner 100. The front side of the panel component 1 has an air outlet 1a. An air outlet grille 2 is covered on the air outlet 1a. The air from the air conditioner 100 flows out through the air outlet 1a and the air outlet grille 2.

[0063] The upper and lower ends of the air outlet grille 2 are both fitted with the panel component 1. The second insertion structure 21 at the upper end of the air outlet grille 2 is inserted and fitted with the first insertion structure 11 on the panel component 1. The second insertion structure 21 is inserted and fitted with the first insertion structure 11 from bottom to top, which can also restrict the upper end of the air outlet grille 2 from detaching forward relative to the panel component 1, so as to restrict the air outlet grille 2 from being disassembled forward relative to the panel component 1.

[0064] The lower end of the air outlet grille 2 engages with the locking mechanism 12. When locked, the locking mechanism 12 pushes the air outlet grille 2 upwards, ensuring that the second insertion structure 21 engages with the first insertion structure 11. This prevents the air outlet grille 2 from being detached downwards or forwards from the panel component 1. This improves the assembly stability of the air outlet grille 2 and the panel component 1, reducing the likelihood of the air outlet grille 2 becoming loose during operation or transportation, and enhancing the operational stability of the air outlet grille 2.

[0065] When the locking mechanism 12 is in the unlocked state, the locking mechanism 12 removes its lifting action on the air outlet grille 2, and the air outlet grille 2 moves downward relative to the panel component 1, releasing the insertion engagement between the second insertion structure 21 and the first insertion structure 11. Then, the air outlet grille 2 can be directly removed forward from the panel component 1 for cleaning or replacement, reducing the dust accumulated on the air outlet grille 2 and improving the air outlet effect of the air conditioner 100.

[0066] According to the embodiment of the present invention, the air conditioner 100 detachably connects the air outlet grille 2 to the panel component 1 by providing a locking mechanism 12. This allows the air outlet grille 2 to be removed from the panel component 1 for cleaning or replacement, reducing dust accumulation on the air outlet grille 2 and improving the airflow efficiency of the air conditioner 100. Furthermore, the disassembly and assembly of the air outlet grille 2 is simple and convenient, facilitating cleaning or replacement.

[0067] In some embodiments of this utility model, such as Figure 2 and Figure 17 As shown, the first plug-in structure 11 is constructed as a plug-in hole 111 extending in the vertical direction, and the second plug-in structure 21 is constructed as an upwardly protruding plug 211, which is inserted into the plug-in hole 111 from bottom to top.

[0068] In some embodiments of this utility model, such as Figure 4 and Figure 5As shown, the lower part of the air vent grille 2 has a support structure 22, and the locking mechanism 12 includes a cam structure 120. The cam structure 120 includes a support portion 12a and a clearance portion 12b. The support portion 12a and the clearance portion 12b are offset circumferentially from each other along the cam structure 120, and the support portion 12a protrudes radially from the clearance portion 12b relative to the clearance portion 12b. The rotation center line of the cam structure 120 extends in the front-rear direction, such as... Figure 4 and Figure 6 As shown, when the structure 22 is rotated to the point where it is supported by the support part 12a, the locking mechanism 12 is in a locked state, as... Figure 5 and Figure 7 As shown, when the cam structure 120 rotates to support the support structure 22 through the relief part 12b, the locking mechanism 12 is in an unlocked state.

[0069] The lower part of the air vent grille 2 has a support structure 22, and the locking mechanism 12 cooperates with the support structure 22. The locking mechanism 12 includes a cam structure 120, which is rotatably mounted on the panel component 1. The cam structure 120 includes a support portion 12a and a clearance portion 12b. The support portion 12a protrudes radially relative to the clearance portion 12b of the cam structure 120, that is, the dimension from the rotation center of the cam structure 120 to the support portion 12a is large, and the dimension from the rotation center of the cam structure 120 to the clearance portion 12b is small.

[0070] like Figure 4 and Figure 6 As shown, when the cam structure 120 rotates to support the support structure 22 via the support part 12a, the cam structure 120 pushes the air outlet grille 2 upward, and the locking mechanism 12 is in the locked state; as Figure 5 and Figure 7 As shown, when the cam structure 120 rotates to support the support structure 22 via the clearance portion 12b, compared to when the support structure 22 is supported via the support portion 12a, the air outlet grille 2 moves downward. That is, the cam structure 120 removes its lifting effect on the air outlet grille 2, and the locking mechanism 12 is in the unlocked state. The cam structure is simple in construction, and the switching between the locked and unlocked states is reliable.

[0071] In some other embodiments of this utility model, the locking mechanism 12 includes a wedge block having a first part that is larger in the vertical direction and a second part that is smaller in the vertical direction. When the wedge block moves to the first part supporting the support structure 22, the locking mechanism 12 is in a locked state; when the wedge block moves to the second part supporting the support structure 22, the locking mechanism 12 is in an unlocked state.

[0072] In some embodiments of this utility model, such as Figure 8As shown, the cam structure 120 includes a cam support 121, a lifting member 122, and an elastic member 123. The lifting member 122 is movable in the radial direction of the cam structure 120 relative to the cam support 121. The elastic member 123 is engaged between the lifting member 122 and the cam support 121 to apply an elastic force to the lifting member 122 in a direction away from the center of the cam structure 120. The lifting member 122 includes a support portion 12a.

[0073] The lifting member 122 includes a support portion 12a. When the lifting member 122 supports the support structure 22, the locking mechanism 12 is in a locked state.

[0074] By applying an elastic force to the lifting member 122 in a direction away from the center of the cam structure 120 through the elastic element 123, the lifting member 122 and the support structure 22 are tightly fitted, improving the stability of the fit. Furthermore, it is understood that the length of the air outlet grille 2 has tolerances. By applying an elastic force to the lifting member 122 in a direction away from the center of the cam structure 120 through the elastic element 123, the air outlet grille 2 is lifted upwards and stabilized, ensuring that the upper position of the air outlet grille 2 remains fixed. This compensates for the gap problem caused by the tolerance of the air outlet grille 2 and improves the overall integrity of the air outlet grille 2 and the panel component 1.

[0075] In some embodiments of this utility model, such as Figure 9 and Figure 10 As shown, the lifting member 122 includes a top plate portion 1223 and a support portion 12a disposed on the side of the top plate portion 1223 away from the center of the cam structure 120; wherein, there are multiple support portions 12a and they are spaced apart on the side of the top plate portion 1223 away from the center of the cam structure 120.

[0076] By setting multiple support parts 12a, the contact area can be reduced, frictional noise can be reduced, frictional resistance can be reduced, the feel can be improved, and frictional wear can be reduced.

[0077] In some embodiments of this utility model, such as Figure 9 and Figure 10 As shown, in the axial section of the cam structure 120, the outline of the support portion 12a is formed as a curve that protrudes in a direction away from the top plate portion 1223.

[0078] The curved surface, in conjunction with the support structure 22, can reduce the contact area, reduce frictional noise, reduce frictional resistance, improve the feel, and reduce frictional wear.

[0079] In some embodiments of this utility model, such as Figure 9 and Figure 10As shown, the support portion 12a is a plurality of portions and is spaced apart on one side of the top plate portion 1223 away from the center of the cam structure 120, and on the axial section of the cam structure 120, the outline of the support portion 12a is formed as a curve protruding in a direction away from the top plate portion 1223.

[0080] Furthermore, compared to the surface-to-surface contact between the support structure 22 and the straight plane, the point-to-point contact formed by the curved surface makes it easier to meet the flatness requirements of the multiple support parts 12a, thereby improving the stability of the fit between the support parts 12a and the support structure 22.

[0081] In some embodiments of this utility model, such as Figure 9 As shown, the lifting member 122 includes a first guide portion 1221, and the cam support 121 includes a second guide portion 1211. The second guide portion 1211 slides with the first guide portion 1221 to limit the radial movement of the lifting member 122 relative to the cam support 121 along the cam structure 120. The lifting member 122 includes a first limiting portion 1222, and the cam support 121 includes a second limiting portion 1212. The second limiting portion 1212 limits the movement of the lifting member 122 toward the extreme position away from the center of the cam structure 120.

[0082] The first guide portion 1221 and the second guide portion 1211 cooperate to provide guidance, which can improve the stability of the lifting member 122's radial movement relative to the cam support 121. The first limiting portion 1222 and the second limiting portion 1212 cooperate to limit the lifting member 122's movement to extreme positions away from the center of the cam structure 120, improve the situation where the lifting member 122 disengages from the cam support 121, and enhance the working stability of the lifting member 122.

[0083] In some embodiments of this utility model, such as Figure 10 As shown, one of the first guide portion 1221 and the second guide portion 1211 includes a sleeve 1211b and the other includes a core post 1221a. The sleeve 1211b is sleeved on the outside of the core post 1221a, and the two can slide relative to each other along the axial direction of the sleeve 1211b. The elastic element 123 is disposed inside the sleeve 1211b and is a spring 1231 sleeved on the outside of the core post 1221a. The spring 1231 abuts against the sleeve 1211b and the core post 1221a along the axial direction of the sleeve 1211b.

[0084] The sleeve 1211b is fitted over the core post 1221a, allowing the core post 1221a to slide stably axially relative to the sleeve 1211b, thus improving the motion stability of the lifting member 122 relative to the cam support 121. Furthermore, by forming the structure of the sleeve 1211b and the core post 1221a, a mounting structure for the spring 1231 can also be provided. The spring 1231 is located inside the sleeve 1211b and fitted over the core post 1221a. The spring 1231 applies an elastic force to the core post 1221a away from the sleeve 1211b, eliminating the need for an additional mounting structure to fix the spring 1231, simplifying the structure, and reducing manufacturing costs.

[0085] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the lifting member 122 includes a top plate portion 1223, a core column 1221a protruding from the top plate portion 1223 toward the center of the cam structure 120, a recessed region 1213 is formed on the outer peripheral surface of the cam support 121 toward the center of the cam structure 120, a sleeve 1211b is disposed at the recessed region 1213 and does not protrude from the recessed region 1213 in the radial direction of the cam structure 120, and at least a portion of the core column 1221a is always located within the recessed region 1213 and cooperates with the sleeve 1211b.

[0086] A recessed area 1213 is formed on the cam support 121, and the recessed area 1213 is provided for the sleeve 1211b. The structure between the lifting member 122 and the cam is compact. At least a portion of the core column 1221a is always located in the recessed area 1213 and cooperates with the sleeve 1211b, which can improve the movement stability of the lifting member 122 relative to the cam.

[0087] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the first guide portion 1221 includes two parallel core posts 1221a, and the second guide portion 1211 includes two parallel sleeves 1211b. The two sleeves 1211b are spaced apart along the circumference of the cam structure 120, and the two core posts 1221a and the two sleeves 1211b are respectively matched.

[0088] By setting two core posts 1221a and two sleeves 1211b respectively to cooperate, compared with setting a single core post 1221a and sleeve 1211b to cooperate, the rotation of the core post 1221a relative to the sleeve 1211b can be avoided, which can improve the cooperation stability between the lifting member 122 and the cam and improve the working reliability of the lifting member 122.

[0089] In some embodiments of this utility model, such as Figure 9 and Figure 10As shown, the lifting member 122 includes a top plate portion 1223. A first guide portion 1221 and a first limiting portion 1222 are both provided on one side of the top plate portion 1223 near the center of the cam structure 120. There are two first limiting portions 1222, which are respectively disposed on both sides of the first guide portion 1221 along the circumference of the cam structure 120. There are two second limiting portions 1212, which are located on both sides of the second guide portion 1211. Each second limiting portion 1212 defines a locking hole 1212d. Each first limiting portion 1222 includes a locking plate 1222c. The locking plate 1222c extends into the locking hole 1212d and moves within the locking hole 1212d as the lifting member 122 moves. The second limiting portion 1212 abuts against the locking plate 1222c through the upper edge of the locking hole 1212d, limiting the lifting member 122 to the extreme position of moving away from the center of the cam structure 120.

[0090] Both the first guide portion 1221 and the first limiting portion 1222 are located on the top plate portion 1223. Compared with placing the first guide portion 1221 and the first limiting portion 1222 on different structures, the structure can be simplified and the structural compactness can be improved.

[0091] The first limiting part 1222 includes a locking plate 1222c, which is disposed on both sides of the first guide part 1221. The locking holes 1212d are formed on both sides of the second guide part 1211. The limiting cooperation between the locking holes 1212d and the locking plate 1222c makes the lifting member 122 stable under force, which can improve the movement stability of the lifting member 122.

[0092] like Figure 9 and Figure 10 As shown, the locking holes 1212d extend vertically and are open to each other, while the locking plates 1222c extend away from each other and are respectively inserted into the corresponding locking holes 1212d. The upper edge of the locking hole 1212d abuts against the locking plate 1222c to restrict the upward movement of the locking plate 1222c, thereby limiting the extreme position of the upward movement of the lifting member 122.

[0093] In some other embodiments of this utility model, a first limiting part 1222 is integrated on the first guide part 1221, and a second limiting part 1212 is integrated on the second guide part 1211. While guiding the lifting member 122 and the cam support 121, the movement of the lifting member 122 can be limited, which can simplify the structure and improve the structural compactness.

[0094] In some embodiments of this utility model, such as Figure 9 As shown, the outer peripheral wall of the cam structure 120 includes a transition portion 12c connecting the support portion 12a and the relief portion 12b. The radius of the cam structure 120 at the transition portion 12c gradually decreases along the direction from the support portion 12a to the relief portion 12b. The support portion 12a and the relief portion 12b are arranged opposite to each other along the diameter direction of the cam structure 120.

[0095] The radius of the cam structure 120 at the support portion 12a is greater than the radius of the cam structure 120 at the clearance portion 12b. The radius of the cam structure 120 at the transition portion 12c gradually decreases along the direction from the support portion 12a to the clearance portion 12b, resulting in a smooth structural transition of the cam structure 120 from the support portion 12a to the clearance portion 12b. When the cam structure 120 rotates to switch the state of the locking mechanism 12, the movement of the air outlet grille 2 will not produce violent fluctuations; the air outlet grille 2 will gradually move upward or downward, improving movement stability.

[0096] Furthermore, the support part 12a and the relief part 12b are arranged opposite each other along the diameter direction of the cam structure 120, and the support part 12a and the relief part 12b are 180° apart. On the basis of smooth transition, the radius difference between the two can be large, which is conducive to the smooth drop of the air outlet grille 2 over a large distance, so as to facilitate the disengagement of the upper plug structure.

[0097] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the clearance portion 12b is formed as a plane extending along the chord of the cam structure 120.

[0098] Under the premise that the radius of the center point of the relief part 12b is fixed, some embodiments of this utility model set the center point of the relief part 12b as the midpoint of the plane. Compared with designing the center point of the relief part 12b as the apex of the arc, the cam structure 120 of this solution has a solid structure on both sides of the center point of the relief part 12b, which improves the overall structural strength of the cam structure 120 and is beneficial to supporting the air outlet grille 2 in the locked state.

[0099] In some embodiments of this utility model, such as Figure 1 As shown, the air conditioner 100 also includes a knob 3. The panel component 1 has a clearance hole 1b below the air outlet 1a. The knob 3 is positioned corresponding to the clearance hole 1b and connected to the cam structure 120 to drive the cam structure 120 to rotate synchronously. Controlling the rotation of the cam structure 120 by setting the knob 3 provides intuitive control and convenient operation.

[0100] In some other embodiments of this utility model, the cam structure 120 can be started to rotate via a button and a linkage mechanism, which is simple to operate and convenient to use.

[0101] In some embodiments of this utility model, such as Figure 12 As shown, the knob 3 is mounted on the front side of the cam structure 120, and the rear side of the knob 3 has a first mating structure 31, as shown. Figure 11As shown, the front side of the cam structure 120 has a second mating structure 124. The first mating structure 31 and the second mating structure 124 form a non-circular surface mating to transmit torque. The knob 3 and the cam structure 120 are connected by fasteners that pass through the first mating structure 31 and the second mating structure 124.

[0102] The rear side of the knob 3 is assembled and connected to the front side of the cam structure 120. The rear side of the knob 3 has a first mating structure 31, and the front side of the cam structure 120 has a second mating structure 124. The first mating structure 31 and the second mating structure 124 form a non-circular surface mating and are also fixedly connected by fasteners to prevent the knob 3 from rotating relative to the cam structure 120 and improve the stability of the knob 3 driving the cam structure 120 to rotate synchronously.

[0103] In some embodiments of this utility model, such as Figure 11 As shown, the second mating structure 124 is formed as a forward-protruding elongated or elliptical protrusion 1241, and the protrusion 1241 has grooves 1242 that are spaced circumferentially and extend radially. The first mating structure 31 is fitted with the second mating structure 124, sleeved on the outside of the protrusion 1241 and inserted into the groove 1242.

[0104] The second mating structure 124 forms a non-circular protrusion 1241, and by providing a slot 1242 on the protrusion 1241, the first mating structure 31 is sleeved on the protrusion 1241 and inserted into the slot 1242, which can improve the stability of the torque transmitted from the knob 3 to the cam structure 120, and can prevent the knob 3 from rotating relative to the cam structure 120, thereby improving the stability of the knob 3 driving the cam structure 120 to rotate synchronously.

[0105] In some specific embodiments of this utility model, such as Figure 11 As shown, the second mating structure 124 is formed as a forward-protruding protrusion 1241. The protrusion 1241 is constructed as an elliptical protrusion 1241 with vertically extending tangents on both the left and right sides. Three slots 1242 are evenly distributed on the protrusion 1241, spaced circumferentially and extending radially. A fixing hole 1243 is provided at the center of the protrusion 1241. Figure 12 As shown, the first mating part includes clamping ribs 311. Two clamping ribs 311 clamp the protrusion 1241 from both sides and mate with the cut edge surface of the protrusion 1241. The first mating part also includes three limiting ribs 312. The limiting ribs 312 are inserted into the groove 1242 one by one, corresponding to the groove 1242. The first mating structure 31 also includes a screw post 313. The screw post 313 extends toward the cam structure 120 and is inserted into the fixing hole 1243. The fastener passes through the fixing hole 1243 from back to front and is fixedly connected to the screw post 313.

[0106] In some embodiments of this utility model, such as Figure 13 As shown, panel component 1 includes mounting plate 13, mounting plate 13 includes recessed groove 131 from front to back, the rear groove surface of groove 131 is an annular ring 132, the annular ring 132 defines a clearance hole 1b, knob 3 is embedded in groove 131 from front to back and the edge of knob 3 abuts against the front side of annular ring 132.

[0107] The mounting plate 13 has a recessed groove 131 extending from front to back. The knob 3 is embedded in the groove 131, which reduces the size of the knob 3 protruding forward from the panel component 1, reduces interference with the outside world, and improves the overall integrity of the air conditioner 100. The rear groove surface of the groove 131 is an annular ring 132, which supports the knob 3 circumferentially, thereby improving the assembly stability of the knob 3.

[0108] In some embodiments of this utility model, such as Figure 13 As shown, panel component 1 includes mounting plate 13, which defines clearance hole 1b. Cam structure 120 is located on the rear side of mounting plate 13, as shown. Figure 11 As shown, the front end of the cam structure 120 has a stop block 125 protruding into the clearance hole 1b. The edge of the clearance hole 1b is provided with a stop ring 133, which restricts the range of motion of the stop block 125 within the clearance hole 1b, so that the cam structure 120 reciprocates between a locking angle that puts the locking mechanism 12 into a locked state and an unlocking angle that puts the locking mechanism 12 into an unlocked state.

[0109] Mounting plate 13 defines clearance hole 1b to allow the knob 3 and cam structure 120 located on the front and rear sides of mounting plate 13 to connect.

[0110] The stop block 125 of the cam structure 120 protrudes into the clearance hole 1b. The edge of the clearance hole 1b protrudes into the clearance hole 1b with a stop ring 133. When the cam structure 120 rotates, the stop block 125 is stopped by the stop ring 133, which restricts the rotation range of the cam structure 120. This allows the cam structure 120 to rotate back and forth between the locking angle that puts the locking mechanism 12 in the locked state and the unlocking angle that puts the locking mechanism 12 in the unlocked state, thereby improving the rotational stability of the cam structure 120 and preventing the cam structure 120 from rotating out of place.

[0111] In some embodiments of this invention, the cam structure 120 rotates 180° from a locking angle that puts the locking mechanism 12 into a locking state to an unlocking angle that puts the locking mechanism 12 into an unlocking state. Therefore, by designing the stop ring 133 and the stop block 125 such that the sum of their coverage angles is 180°, the cam structure 120 can be limited to rotating only 180°, thus improving the rotational stability of the cam structure 120.

[0112] In some embodiments of this utility model, the knob 3 includes a knob handle 32 extending along the diameter direction of the knob 3. The knob handle 32 has a direction indication structure. The knob 3 can rotate at least 180° to switch to a locked state when the direction indication structure is rotated to face upward, and to switch to an unlocked state when the direction indication structure is rotated to face downward.

[0113] By setting a directional diagram on the knob handle, the indication is clear, making it easy to determine whether to unlock or lock, and making it convenient to use.

[0114] In some specific embodiments of this utility model, the directional indication structure on the knob 3 is constructed as an arrow. When the arrow points upward, it indicates that the locking mechanism 12 is switched to the locked state, and when the arrow points downward, it indicates that the locking mechanism 12 is switched to the unlocked state.

[0115] In some embodiments of this utility model, such as Figure 13 and Figure 15 As shown, panel component 1 includes mounting plate 13, which includes upper plate segment 134 and lower plate segment 135. Lower plate segment 135 protrudes forward relative to upper plate segment 134, and a step portion 136 is formed between upper plate segment 134 and lower plate segment 135. A limiting hole 1361 extending through in the vertical direction is formed on the step portion 136. The lower end of support structure 22 extends into the limiting hole 1361 and stops at the rear side of the upper end of lower plate segment 135. Cam structure 120 is located at the rear side of lower plate segment 135 and is lower than the upper edge of lower plate segment 135, so that the lower end of support structure 22, which is supported by support portion 12a in the locked state, is still kept in the limiting hole 1361 and stopped at the rear side of the upper end of lower plate segment 135.

[0116] The cam structure 120 is located on the rear side of the lower plate section 135, and most of the air outlet grille 2 is located on the front side of the mounting plate 13. Therefore, the mounting plate 13 is designed as a stepped structure, and a limiting hole 1361 is formed on the stepped portion 136 between the upper plate section 134 and the lower plate section 135. The limiting hole 1361 allows the lower end of the support structure 22 to extend into it, thereby contacting the cam structure 120 located on the rear side.

[0117] Furthermore, by designing the mounting plate 13 as a stepped structure, the lower end of the support structure 22 extends into the limiting hole 1361 and stops at the rear side of the upper end of the lower plate section 135. The lower plate section 135 of the mounting plate 13 restricts the support structure 22 from moving forward relative to the panel component 1. Since the size of the support structure 22 extending into the limiting hole 1361 is relatively large, when the locking mechanism 12 is in the locked state, the cam structure 120 lifts the support structure 22. Even when lifted, the support structure 22 remains within the limiting hole 1361 and stops at the rear side of the upper end of the lower plate section 135. Thus, when the locking mechanism 12 is in the locked state, the upper end of the air outlet grille 2 is inserted into the panel component 1, and the lower end of the air outlet grille 2 is inserted into the mounting plate 13. The air outlet grille 2 cannot move forward relative to the panel component 1, and the air outlet grille 2 cannot move relative to the panel component 1 in the vertical direction, thereby stably assembling the air outlet grille 2 and the panel component 1.

[0118] In some embodiments of this utility model, such as Figure 15 As shown, the lower end of the support structure 22 extends obliquely downwards and backwards; and / or, the cam structure 120 includes a cam support 121, a lifting member 122, and an elastic member 123. The lifting member 122 is movable radially relative to the cam support 121 in the cam structure 120. The elastic member 123 is engaged between the lifting member 122 and the cam support 121 to apply an elastic force to the lifting member 122 in a direction away from the center of the cam structure 120. The lifting member 122 includes a support portion 12a and a top plate portion 1223. The support portion 12a is located on the side of the top plate portion 1223 away from the center of the cam structure 120, and the center of the support portion 12a in the front-rear direction is offset forward relative to the center of the top plate portion 1223 in the front-rear direction.

[0119] By setting the elastic element 123 to apply an elastic force to the lifting element 122 in a direction away from the center of the cam structure 120, the lifting element 122 and the support structure 22 are closely matched, improving the stability of the matching.

[0120] The lifting member 122 includes a support portion 12a. When the lifting member 122 supports the support structure 22, the locking mechanism 12 is in a locked state. The lower end of the support structure 22 extends obliquely downward and backward; and / or, the center of the support portion 12a in the front-rear direction is offset forward relative to the center of the top plate portion 1223 in the front-rear direction, and the support structure 22 extends toward the support portion 12a. The extension of the support portion 12a toward the support structure 22 can improve the stability of the cooperation between the support structure 22 and the support portion 12a.

[0121] By extending the lower end of the support structure 22 at an angle to the rear and downward, the bottom of the air outlet grille 2 can be flush with the front surface of the lower plate section 135. The support structure 22 extends to the rear and downward into the limiting hole 1361, which helps the air outlet grille 2 to be flush with the front surface of the lower plate section 135, thus improving the integrity of the air outlet grille 2 and the panel component 1.

[0122] In some embodiments of this utility model, such as Figure 13 and Figure 16 As shown, a through-hole 1362 is also formed on the stepped portion 136, and a downwardly extending pin 23 is also formed on the lower part of the air outlet grille 2, as shown. Figure 17 As shown, in the unlocked state, the support structure 22 is supported by the clearance portion 12b, and the air outlet grille 2 can be moved downward so that the pin 23 is inserted downward into the socket 1362 and stopped at the rear side of the upper end of the lower plate section 135.

[0123] The lower part of the air vent grille 2 also has a downwardly extending pin 23. In the unlocked state, the locking mechanism 12 removes its lifting action on the air vent grille 2, and the air vent grille 2 moves downward relative to the panel component 1. By setting the pin 23 to cooperate with the insertion hole 1362, when the second insertion structure 21 of the air vent grille 2 disengages downward from the cooperation with the first insertion structure 11, the air vent grille 2 cooperates with the panel component 1 not only through the support structure 22, but also through the pin 23. This can improve the stability of the air vent grille 2 in the unlocked state and reduce the possibility of the air vent grille 2 directly detaching from the panel component 1.

[0124] In some embodiments of this utility model, such as Figure 16 As shown, there are two pins 23, which are placed on both sides of the support structure 22 along the left and right directions. This can improve the stress stability of the air outlet grille 2 and improve the stability of the air outlet grille 2 relative to the panel component 1 when the locking mechanism 12 is in the unlocked state.

[0125] In some embodiments of this utility model, such as Figure 13 and Figure 16 As shown, the mounting plate 13 includes a positioning part 137, which extends upward from the left and right ends of the stepped part 136. The lower part of the air outlet grille 2 has a mating structure 24, and the support structure 22 extends downward from the mating structure 24. In the unlocked state, the mating structure 24 is positioned between the positioning parts 137 on both sides to restrict the left and right movement of the lower part of the air outlet grille 2.

[0126] By setting the cooperation between the cooperating structure 24 and the positioning part 137, when the second insertion structure 21 of the air outlet grille 2 disengages downward from the cooperation with the first insertion structure 11, the air outlet grille 2 not only cooperates with the panel component 1 through the support structure 22, but also cooperates with the positioning part 137 through the cooperating structure 24, which restricts the left and right movement of the lower part of the air outlet grille 2. This can improve the stability of the air outlet grille 2 in the unlocked state of the locking mechanism 12 and reduce the possibility of the air outlet grille 2 directly detaching from the panel component 1.

[0127] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the air conditioner 100 also includes an upper panel 4 and a lower panel 5. The upper panel 4 is located above the air outlet grille 2 and at least partially covers the top front side of the air outlet grille 2. The lower panel 5 is located below the air outlet grille 2 and at least partially covers the bottom front side of the air outlet grille 2. The lower panel 5 can also cover the locking mechanism 12 on the rear side. By setting the upper panel 4 and the lower panel 5, the connection reliability between the air outlet grille 2 and the panel component 1 can be improved.

[0128] The following describes the disassembly and assembly process of the air outlet grille 2 of an air conditioner 100 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0129] The air vent grille 2 is oriented vertically along its length. The top of the air vent grille 2 is inserted into the panel component 1 from bottom to top, and the bottom of the air vent grille 2 is inserted into the panel component 1 from top to bottom. The top of the air vent grille 2 is restricted from detaching forward relative to the panel component 1, and the bottom of the air vent grille 2 is restricted from detaching forward relative to the panel component 1.

[0130] During the assembly process, the lower end of the air outlet grille 2 is first inserted into the panel component 1 from top to bottom. Then, the air outlet grille 2 is moved upward so that the upper end of the air outlet grille 2 is inserted into the panel component 1 from bottom to top. Finally, the locking mechanism 12 lifts the air outlet grille 2 upward. Both the upper and lower ends of the air outlet grille 2 are restricted from detaching from the panel component 1. The air outlet grille 2 also moves relative to the panel component 1 in the vertical direction, thereby stably assembling the air outlet grille 2 and the panel component 1.

[0131] During disassembly, the entire sequence is reversed. First, the locking mechanism 12 is removed from lifting the air outlet grille 2, and the air outlet grille 2 moves downward relative to the panel component 1. Then, the upper end of the air outlet grille 2 is naturally disengaged from the panel component 1. Next, the top of the air outlet grille 2 is pulled outward and moved upward, and the air outlet grille 2 is removed from the panel component 1 from bottom to top.
