Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] When cleaning, repairing, or replacing parts of a ceiling-mounted or wall-mounted air conditioner, the grille needs to be removed to expose the air vents and allow for inspection and maintenance of the internal components.

[0003] The operator faces difficulties in disassembling and assembling the grille for air conditioner maintenance, such as... Figure 1 As shown, when the grille is rotated to open the air vent with one side as a reference, the grille is suspended on the air conditioner, obstructing the operator's view and operating space. Additionally, as... Figure 2 As shown, when an air conditioner is installed against a wall, the rotating grille hangs on the air conditioner, which not only affects the operator's working space, but also causes the grille to interfere with the wall when it is rotated open, making it impossible to open to the set angle. This makes it difficult for the operator to inspect and maintain the internal components of the air conditioner. Utility Model Content

[0004] The main purpose of this utility model is to propose an air conditioner that aims to improve the ease of operation for air conditioner inspection and maintenance.

[0005] To achieve the above objectives, the air conditioner proposed in this utility model includes: A housing having an air vent and a positioning portion located around the air vent; and A grille, covering the air vent, includes a grille body and a positioning and mating part disposed on the grille body. The grille has an assembly position where it is limited and engaged with the positioning part by the positioning and mating part, a transition position where it is positioned and engaged with the positioning part by the positioning and mating part, and a separation position where it is separated from the positioning part by the positioning and mating part. When the grille is in the separation position, the grille is separated from the housing. The grille is used to reciprocate along a first direction to switch between the assembly position and the transition position, and the grille is used to reciprocate along a second direction to switch between the transition position and the separation position. The first direction and the second direction are intersecting.

[0006] In one embodiment, one of the positioning part and the positioning mating part is configured as a snap groove, and the other is configured as a sliding buckle. The snap groove has a slot and an overlapping surface arranged sequentially along a first direction. The sliding buckle is inserted into the slot for positioning and mating along a second direction, and overlaps and limits the mating surface along the second direction.

[0007] In one embodiment, the sliding buckle includes a connecting portion and an overlapping portion. The overlapping portion is connected to the grille body or the housing through the connecting portion. The overlapping portion is bent relative to the connecting portion. The overlapping portion is provided with an overlapping mating surface. The overlapping mating surface and the overlapping surface overlap and limit each other in a second direction.

[0008] In one embodiment, a supporting rib is provided on the side of the overlapping portion away from the connecting portion.

[0009] In one embodiment, the lap joint further has a guide surface, which is located on the side of the lap mating surface away from the connecting portion, and the guide surface is inclined relative to the lap mating surface toward the side closer to the supporting rib.

[0010] In one embodiment, the air conditioner further includes fasteners, and the housing also has a fastening fitting. When the grille is in the assembled position, the fasteners and the fastening fitting are detachably connected to each other to detachably fix the grille to the housing.

[0011] In one embodiment, a plurality of grilles are provided, and the plurality of grilles are arranged sequentially along a first direction at the air outlet; And / or, the grille body is provided with a plurality of positioning mating parts on both sides along a third direction, the housing has a plurality of positioning parts, the plurality of positioning parts and the plurality of positioning mating parts are arranged one-to-one, and the first direction, the second direction and the third direction are arranged to intersect each other.

[0012] In one embodiment, the air vent has a first end and a second end disposed opposite to each other along a first direction, each of the grille members has a transition position and an assembly position disposed sequentially from the first end to the second end, the plurality of grille members include a first grille member and at least one second grille member, the first grille member and at least one second grille member abutting each other sequentially from the first end to the second end, the fastener is used to fasten the first grille member in the assembly position to the housing, so as to restrict the movement of each second grille member from the assembly position to the transition position.

[0013] In one embodiment, the second direction is the up-down direction; The air conditioner has an installation state for mounting on a carrier, and when the air conditioner is in the installation state, the air vent is at least partially located on the bottom side of the housing.

[0014] In one embodiment, the housing includes a chassis and a panel, the chassis and the panel enclosing each other to form the air vent, the air vent being configured as the air outlet of the air conditioner, the chassis and the panel respectively having the positioning part, the grille body corresponding to the chassis and the panel respectively having the positioning mating part, the positioning part and the positioning mating part being configured in a one-to-one correspondence.

[0015] The technical solution of this utility model involves setting an air conditioner including a casing and a grille. The casing has an air vent and a positioning part. The grille includes a grille body and a positioning mating part located on the grille body. The grille can reciprocate along a first direction, allowing it to switch between an assembly position where the positioning mating part and the positioning part are in a limited fit, and a transition position where the positioning mating part and the positioning part are in a positioning fit. Furthermore, the grille can reciprocate along a second direction, allowing it to switch between a transition position where the positioning mating part and the positioning part are in a positioning fit, and a separation position where the positioning mating part and the positioning part are separated. The first direction is horizontal, and the second direction is vertical. When the grille is positioned, it can move upward to the air outlet for pre-positioning through the cooperation of the positioning part and the positioning mating part, and then move horizontally to the assembly position limited by the air outlet, so that the grille can be hung on the air outlet. When the grille is fixed in the assembly position with screws, and when the screws on the grille in the assembly position are removed, the grille will not fall off. The operator does not need to hold the grille while operating the screws on the grille, which can save manpower and improve the convenience of grille disassembly and assembly. In addition, when the grille is in the separated position, it is completely separated from the air outlet and will not hang on the casing, so it will not interfere with the operator's inspection and maintenance, thus facilitating the inspection and maintenance of the air conditioner.

[0023] The grille and filter are fixed to the air outlet or inlet of the air conditioner with multiple screws, and are either suspended from the ceiling along with the air conditioner or installed against the wall using a tripod. When the air conditioner is suspended from the ceiling, removing and installing the grille is very time-consuming when cleaning, repairing, or replacing parts. Moreover, due to gravity, operators must also free their hands to hold the falling grille while removing and installing the screws, which is labor-intensive.

[0024] This utility model proposes an air conditioner 100.

[0025] Please see Figures 3 to 12In one embodiment of the present invention, the air conditioner 100 includes a housing 10 and a grille 20; the housing 10 has an air vent 101 and a positioning portion 11 located on at least one side of the air vent 101; the grille 20 covers the air vent 101, and the grille 20 includes a grille body 21 and a positioning engagement portion 22 disposed on the grille body 21; the grille 20 has an assembly position in which the positioning engagement portion 22 is limited to the positioning portion 11, a transition position in which the positioning engagement portion 22 is positioned to engage with the positioning portion 11, and a separation position in which the positioning engagement portion 22 is separated from the positioning portion 11; when the grille 20 is in the separation position, the grille is separated from the housing; the grille 20 is used to reciprocate along a first direction to switch between the assembly position and the transition position; the grille 20 is used to reciprocate along a second direction to switch between the transition position and the separation position; the first direction and the second direction are intersecting.

[0026] The air conditioner 100 of this utility model can be a split-type air conditioner 100. The casing 10 of the air conditioner 100 can be the outer shell of the indoor unit. The indoor unit can be installed on a carrier such as a ceiling or wall by means of hanging or wall mounting. The air vent 101 provided on the casing 10 can be an air inlet 101 or an air outlet 101. The positioning part 11 provided on the periphery of the air vent 101 can be a positioning rib, and the positioning mating part 22 provided on the grille body 21 can be a corresponding positioning groove. Alternatively, the positioning part 11 provided on the periphery of the air vent 101 can be a positioning groove, and the positioning mating part 22 provided on the grille body 21 can be a corresponding positioning groove, and the two can be inserted for positioning. Alternatively, the positioning part 11 can be a hanging ear, and the positioning mating part 22 can be a hook, and the two can be interlocked to realize the pre-positioning of the grille body 21 at the air vent 101, so that the positioning part 11 is in the assembly position for assembly with the positioning mating part 22.

[0027] When disassembling the grille, first remove the screws securing the grille, then move the grille along the first direction. The positioning engagement part 22 located on the grille body 21 can move along the first direction with the grille member 20. The positioning engagement part 22 moves from a state of being limited and engaged with the positioning part 11 to a state of being positioned and engaged with the positioning part 11, corresponding to the grille member 20 moving from the assembly position to the transition position. Furthermore, the positioning engagement part 22 can also move along the second direction with the grille member 20, moving from a positioning state of being positioned and engaged with the positioning part 11 to a separation state of being separated from the positioning engagement part 11, corresponding to the grille member 20 moving from the transition position to the separation position, separating from the housing 10. When the first direction is horizontal and the second direction is vertical, the grille member 20 first moves a distance horizontally, so that the positioning engagement part 22 is no longer limited and engaged with the positioning part 11, and then moves a distance vertically, that is, separates from the positioning part 11.

[0028] During the installation of the grille 20, the positioning mating part 22 of the grille 20 is first aligned with the positioning part 11 and moved upward a certain distance to be positioned near the air vent 101. Then, the grille 20 is moved horizontally a certain distance so that it can be hung at the air vent 101 through the limiting mating part's limiting engagement. At this time, when the operator fixes the grille to the air vent 101 with screws or other fasteners 30, the grille 20 will not sag due to its own weight. During the grille removal stage, when the operator unscrews the screws fixing the grille, because the positioning mating part 22 and the positioning part 11 are in the assembly position, the grille 20 will not fall under its own weight. The operator can easily unscrew the screws and then move the grille 20 to remove it from the air vent 101.

[0029] Understandably, since the positioning and fitting part 22 is located on the grille body 21 and the positioning part 11 is located on the housing 10, when the positioning and fitting part 22 is separated from the positioning part 11, the grille 20 is in a separated position, and the grille 20 is separated from the housing 10. When the positioning and fitting part 22 is positioned and fitted with the positioning part 11, the grille 20 is in a transition position, and the grille 20 is positioned with the air vent 101 on the housing 10, which facilitates the movement of the grille 20 to the assembly position where it is assembled with the housing 10. That is, the positioning and fitting part 22 is moved to a position where it is limited and fitted with the positioning part 11, so that the grille 20 is moved to the assembly position. In the assembly position, the grille 20 is hung at the air vent 101 through the limited fit between the positioning part 11 and the positioning and fitting part 22. The operator can fix the grille 20 to the housing 10 with screws without holding the grille 20 by hand, or unscrew the screws on the grille 20.

[0030] Understandably, compared to the method where the grille 20 remains suspended on the side of the air vent 101 after the positioning and fitting part 22 separates from the positioning part 11, when the indoor unit of the air conditioner is installed against the wall, the grille 20 can rotate open, and when the positioning part 11 separates from the positioning and fitting part 22, it can prevent the grille 20 from interfering with the wall when it rotates open, thus preventing it from being unable to open to a specific angle. This would be detrimental to the operator's inspection and maintenance of the indoor unit. It can also prevent the grille 20 from being suspended on the casing 10 when open, interfering with the operator's vision and operating space. In this utility model, when the positioning part 11 separates from the positioning and fitting part 22, the grille 20 moves as a whole in two directions, which can achieve complete separation from the casing 10. This avoids the grille 20 interfering with the wall after it rotates open, or the grille 20 rotating open to the opposite side of the wall, which would result in a narrow operating space for the operator to perform maintenance on the indoor unit between the wall and the grille 20.

[0031] It is understandable that when cleaning, repairing, or replacing parts of the indoor unit of an air conditioner, the grille needs to be disassembled and installed. When the indoor unit is installed on the ceiling or wall using a hanging or wall-mounted method, it is usually suspended high above the operator. When disassembling and installing the grille, the grille is affected by its own weight, and the operator needs to use their hands to hold the grille in place while removing or installing the screws, making the operation difficult. To address this, this utility model provides a positioning and mating part 22 of the grille body 21 that cooperates with the positioning part 11 around the air vent 101. When the first direction is horizontal and the second direction is vertical, when the operator removes or installs the grille 20 by removing or installing the screws on the grille, the grille 20 can be suspended from the air vent 101 by its own limiting cooperation with the positioning part 11. This eliminates the need to hold the grille while operating the screws on it, saving manpower and improving the efficiency of grille disassembly and installation, thereby facilitating the inspection and maintenance of the air conditioner 100.

[0032] The technical solution of this utility model is to provide an air conditioner 100 including a housing 10 and a grille 20. The housing 10 has an air vent 101 and a positioning part 11. The grille 20 includes a grille body 21 and a positioning mating part 22 located on the grille body 21. The grille 20 is designed to reciprocate along a first direction, allowing it to switch between an assembly position where the positioning mating part 22 and the positioning part 11 are in a limited engagement, and a transition position where the positioning mating part 22 and the positioning part 11 are in a positioning engagement. Furthermore, the grille 20 is designed to reciprocate along a second direction, allowing it to switch between a transition position where the positioning mating part 22 and the positioning part 11 are in a positioning engagement, and a separation position where the positioning mating part 22 and the positioning part 11 are separated. When the first direction is set... When one direction is horizontal and the other is vertical, the grille 20 can move upward to the air outlet 101 for pre-positioning through the cooperation of the positioning part 11 and the positioning mating part 22, and then move horizontally to the assembly position limited by the air outlet 101, so that the grille 20 can be hung on the air outlet 101. When the grille 20 is fixed to the assembly position with screws, and when the screws on the grille 20 are removed, the grille 20 will not fall off. The operator does not need to hold the grille while operating the screws on the grille, which can save manpower and improve the efficiency of grille disassembly and assembly. In addition, when the grille is in the separated position, it is completely separated from the air outlet and will not hang on the casing, which will not interfere with the operator's inspection and maintenance, thus facilitating the inspection and maintenance of the air conditioner 100.

[0033] like Figure 4 , Figure 5 , Figure 8 As shown, in one embodiment, one of the positioning part 11 and the positioning mating part 22 is configured as a fastening groove 11a and the other is configured as a sliding buckle 22a. The fastening groove 11a has a slot 111 and an overlapping surface 112 arranged sequentially along a first direction. The sliding buckle 22a is inserted into the slot 111 for positioning and mating along a second direction, and overlaps and limits the overlap surface 112 along the second direction.

[0034] Understandably, when the slot 111 and the overlapping surface 112 are sequentially arranged along the first direction, the positioning and mating part 22 can first move along the second direction toward the slot 111 and be inserted into the slot 111. That is, the grille 20 moves from the separated position to the transition position, and the grille body 21 moves with the positioning part 11 until it is positioned with the air vent 101. When the positioning and mating part 22 is inserted into the slot 111, the positioning and mating part 22 can move along the first direction toward the overlapping surface 112 and overlap and limit with the overlapping surface 112. That is, the grille 20 moves from the transition position to the assembly position, and the grille body 21 moves with the positioning part 11 until it is limited and overlaps with the housing 10. When the first direction is horizontal and the second direction is vertical, the positioning part 11 is a snap-fit ​​groove 11a. The groove 111 faces downwards, and the overlapping surface 112 is located inside the housing 10, facing upwards. The width of the sliding buckle 22a is not greater than the width of the groove 111, allowing the sliding buckle 22a to be inserted from the groove 111 into the snap-fit ​​groove 11a. The sliding buckle 22a can be configured with a wider portion and a narrower portion. After the sliding buckle 22a is inserted into the groove 111, the wider portion of the sliding buckle 22a can move horizontally, thus overlapping on the overlapping surface 112. This allows the grille 20 to be positioned and suspended at the air vent 101. Alternatively, the positioning part 11 can be a snap-fit ​​groove 11a, and the positioning mating part 22 can be a sliding buckle 22a. The snap-fit ​​groove 11a can be located on the side of the grille, and the sliding buckle 22a can be located on the housing 10 near the air vent 101. Further details are omitted here.

[0035] The structure of the sliding buckle 22a is further described below, such as... Figure 5 , Figure 8 As shown, in one embodiment, the sliding buckle 22a includes a connecting portion 221 and an overlapping portion 222. The overlapping portion 222 is connected to the grille body 21 or the housing 10 through the connecting portion 221. The overlapping portion 222 is bent relative to the connecting portion 221. The overlapping portion 222 is provided with an overlapping mating surface 222a. The overlapping mating surface 222a and the overlapping surface 112 overlap and limit each other in a second direction.

[0036] The positioning part 11 can be configured as a buckle groove 11a, and the positioning mating part 22 can be configured as a sliding buckle 22a. In this case, the overlapping part 222 is connected to the grille body 21 through the connecting part 221. The buckle groove 11a has the slot 111 opened along the second direction and the overlapping surface 112 disposed in the housing 10 along the second direction. The overlapping mating surface 222a of the overlapping part 222 overlaps and limits the overlapping surface 112 along the second direction.

[0037] The groove 11a can be a mounting cavity set inside the housing 10. A slot 111 is opened at the lower end of the mounting cavity to form the groove 11a. The mounting cavity can have an upward-facing inner wall surface, and the inner wall surface near the slot 111 can form an overlapping surface 112. It can be understood that when the overlapping mating surface 222a is set opposite to the grille body 21, after the grille 20 is installed to the air outlet 101, the overlapping mating surface 222a can face the overlapping surface 112. Through the overlapping mating surface 112 and the overlapping mating surface 222a in the second direction (which can be the vertical direction), the positioning mating part and the overlapping surface 112 can make surface-to-surface contact, which can increase the contact area between the two, thereby improving the support effect of the overlapping surface 112 on the sliding buckle 22a.

[0038] When the grating 20 is in the transition position and the assembly position, the connecting part 221 can be extended along the second direction, and the overlapping part 222 can be extended along the first direction, that is, the sliding buckle 22a is in the shape of an inverted L.

[0039] It is understandable that the overlapping portion 222 and the connecting portion 221 are bent, and the dimension of the sliding buckle 22a in the first direction is the sum of the dimensions of the overlapping portion 222 in the first direction and the dimensions of the overlapping portion 222 in the first direction. In this case, it can be satisfied that the dimension of the sliding buckle 22a in the first direction is not greater than the dimension of the slot 111 in the second direction. When the sliding buckle 22a moves in the second direction to the point that the overlapping portion 222 is located within the buckle slot 11a, the movement of the sliding buckle 22a as a whole in the first direction will not cause the overlapping portion 222 to interfere with the slot 111, so that the overlapping portion 222 can move toward the overlapping surface 112 and overlap with the overlapping surface 112, so that the sliding buckle 22a is in the assembly position.

[0040] With this configuration, the overlapping part 222 ensures that the overlapping mating surface 222a can be accurately moved into the fastening groove 11a and overlapped with the overlapping surface 112.

[0041] It is understandable that, since the overlap 222 is a bent connection 221, to avoid the sliding buckle 22a having an excessively large width in the first direction, the sliding buckle 22a would need to move a long distance laterally in the first direction to allow the grille 20 to switch between the transition position and the assembly position, which would be detrimental to the assembly of the grille 20 with the air vent 101 in the first direction. Therefore, setting the lateral width of the sliding buckle 22a in the first direction to be small results in both the width of the connection 221 and the width of the overlap 222 being small, which may lead to insufficient structural strength of the sliding buckle 22a. Optionally, such as... Figure 5 As shown, the overlapping portion 222 has a supporting rib portion 223 on the side away from the connecting portion 221.

[0042] This design increases the structural strength of the slide 22a by adding supporting ribs 223 in the second direction. It also prevents the slide 22a from having an excessively large lateral width, which could affect the movement of the grid member 20 along the first direction during installation. The supporting ribs 223 can be formed by connecting multiple intersecting ribs, or by arranging multiple ribs vertically at intervals and connecting them sequentially; no specific limitation is made here.

[0043] like Figure 5 As shown, optionally, the overlapping portion 222 also has a guide surface 222b, which is located on the side of the overlapping mating surface 222a away from the connecting portion 221, and the guide surface 222b is inclined relative to the overlapping mating surface 222a toward the side closer to the supporting rib portion 223.

[0044] It is understandable that when the positioning mating part 22 is configured as a sliding buckle 22a, when the guide surface 222b is inclined relative to the overlapping mating surface 222a toward the side closer to the support rib part 223, the guide surface 222b is inclined relative to the overlapping part 222 toward the side away from the grid body 21. Along the second direction, the thickness of the overlapping part 222 is thinner on the side closer to the guide surface 222b, and the thickness is thinner the closer to the overlapping part 222 on the side away from the connecting part 221. When the grid part 20 moves along the first direction from the transition position to the assembly position, this position first moves toward the overlapping surface 112. When the overlapping part 222 is provided with a guide surface 222b that connects to the overlapping mating surface 222a, the sliding buckle 22a can be guided by the guide surface 222b and move obliquely from the edge of the slot 111 into the buckle groove 11a, so that the overlapping mating surface 222a can slide to the overlapping surface 112 and overlap with the overlapping surface 112, making the grid part 20 move more smoothly from the transition position to the assembly position, and making it easier for the operator to assemble the grid part 20.

[0045] like Figure 7 , Figure 8 As shown, in one embodiment, the air conditioner 100 further includes a fastener 30, and the housing 10 also has a fastening fitting 12. When the grille 20 is in the assembled position, the fastener 30 and the fastening fitting 12 are detachably connected to each other to detachably fix the grille 20 to the housing 10.

[0046] The fastener 30 can be a screw, threaded rod, rivet, or other similar structure. The fastening mating part 12 can be a threaded post, nut, or other similar structure. The fastener 30 and the fastening mating part 12 are connected by threads to achieve a detachable connection. The fastener 30 can be directly mounted on the grille 20 or inserted into a through hole on the grille 20.

[0047] It is understandable that when the grille 20 is in position, the grille can move along the first direction and is already limited to the position of the air vent 101. Therefore, only one fastener 30 needs to be set to cooperate with the sliding buckle 22a to fix the grille 20 in the assembly position of the air vent 101.

[0048] The fastening fitting 12 may have a downward-facing threaded hole, and the fastener 30 is threadedly connected to the threaded hole upwards. This makes the installation direction of the fastener 30 convenient for operators and conforms to their operating habits.

[0049] like Figure 3 , Figure 12 As shown, in one embodiment, the second direction is the up-down direction; The air conditioner 100 has an installation state for mounting on a carrier, and when the air conditioner 100 is in the installation state, the air vent 101 is at least partially located on the bottom side of the housing 10.

[0050] The carrier can be a wall or a ceiling. When the air conditioner 100 is installed on a wall, the indoor unit of the air conditioner 100 is wall-mounted. When the air conditioner 100 is installed on a ceiling, the indoor unit of the air conditioner 100 is suspended. When installing with a carrier, it can be fixed to the carrier using a tripod 200.

[0051] The air vent 101 is at least partially located on the bottom side of the housing 10. This can be because, when the air conditioner 100 is in the installation state, the air vent 101 is entirely located on the bottom side of the housing 10; or, when the air conditioner 100 is in the installation state, the air vent 101 is partially located on the bottom side of the housing 10, and the other part is located on the periphery of the housing 10.

[0052] Understandably, when the second direction is vertical and the air vent 101 is at least partially located on the bottom side of the housing 10, it allows the operator to easily move the grille 20 from top to bottom to position it with the air vent 101, placing the grille 20 in a transitional position. Then, the grille 20 can be moved laterally along the second direction to completely cover the air vent 101, placing it in the assembly position. The operator can then secure the grille 20 using the fasteners 30 without needing to hold it. Alternatively, when removing the grille 20 and removing the fasteners 30, the grille 20 remains covered by the vent 101 due to the limiting engagement of the sliding buckle 22a and the overlapping surface 112, preventing it from falling off. After removing the fasteners 30, the grille 20 can be removed by simply moving it laterally a short distance along the second direction and then lifting it downwards.

[0053] Compared to the insertion method of rotating and opening the grille 20, the wall-mounted installation of the air conditioner 100 avoids interference between the grille 20 and the wall when it is rotated open. Compared to the method of directly removing and installing the grille 20, the operator does not need to hold the grille 20, saving manpower. This improves the convenience of air conditioner maintenance.

[0054] like Figure 3 As shown, in one embodiment, there are multiple grille members 20, and the multiple grille members 20 are arranged sequentially along the first direction at the air outlet 101.

[0055] Understandably, when the grille structure covering the air vent 101 is configured with multiple grille components 20, the weight of each grille component 20 is lighter than the weight of the entire grille structure, thus facilitating disassembly and assembly operations. Furthermore, the arrangement direction of the multiple grille components 20 is the same as the direction of movement of the grille components 20 between transition and assembly positions, ensuring that the disassembly and assembly direction of a single grille component 20 does not interfere with adjacent grille components 20. This further enhances the ease of operation for operators in disassembling and assembling the grille components 20.

[0056] like Figure 3 As shown, in one embodiment, the air vent 101 has a first end 101a and a second end 101b disposed opposite to each other along a first direction. Each grille 20 has a transition position and an assembly position disposed sequentially from the first end 101a to the second end 101b. The plurality of grilles 20 include a first grille 20a and at least one second grille 20b. The first grille 20a and at least one second grille 20b abut against each other sequentially from the first end 101a to the second end 101b. The fastener 30 is used to fasten the first grille 20a in the assembly position to the housing to restrict each second grille 20b from moving from the assembly position to the transition position.

[0057] In this utility model, the first direction can be left-right, the first end 101a can be located on the left side of the housing 10, and the second end 101b can be located on the right side of the housing 10. It is understood that when multiple grille pieces 20 are arranged sequentially from left to right on the air vent 101, with each grille piece 20 positioned closer to the right and the transition position closer to the left, when all grille pieces 20 are in their assembled positions and adjacent grille pieces 20 abut against each other, the fastener 30 only needs to fix the leftmost grille piece 20. When the remaining grille pieces 20 move to the left towards their corresponding transition positions, they will be limited by the leftmost grille piece 20 and unable to move.

[0058] Therefore, this utility model sets multiple grille pieces 20 as a first grille piece 20a and at least one second grille piece 20b, which are locked and fixed by fasteners 30. The first grille piece 20a and at least one second grille piece 20 abut against each other sequentially from the first end 101a to the second end 101b. Each grille piece 20 has a transition position and an assembly position sequentially arranged from the first end 101a to the second end 101b. When the first grille piece 20a is locked in the assembly position by the fasteners 30, the movement of the remaining second grille pieces 20b can be prevented, thereby reducing the number of fasteners 30. The fixing of multiple grille pieces 20 can be achieved with only a single fastener 30, thus facilitating the installation and removal of the grille pieces 20 on the housing 10 and benefiting the inspection and maintenance of the air conditioner 100.

[0059] like Figure 3 , Figure 6 , Figure 7 , Figure 9 As shown, in one embodiment, the grille body 21 is provided with a plurality of positioning mating parts 22 on both sides along a third direction, and the housing 10 has a plurality of positioning parts 11. The plurality of positioning parts 11 and the plurality of positioning mating parts 22 are arranged one-to-one, and the first direction, the second direction and the third direction are arranged to intersect each other.

[0060] It is understandable that when multiple positioning and mating parts 22 are provided on both sides of the grille body 21 along the third direction, the grille body 21 and the housing 10 are subjected to more balanced forces when the grille part 20 is in the assembly position, and it is less likely that the grille body 21 will tilt and detach on one side.

[0061] The structure of housing 10 is described below. Figure 1 , Figure 10 As shown, in one embodiment, the housing 10 includes a chassis 10a and a panel 10b, the chassis 10a and the panel 10b forming the air vent 101, the air vent 101 being configured as the air outlet 101 of the air conditioner 100, the chassis 10a and the panel 10b respectively having the positioning part 11, the grille body 21 corresponding to the chassis 10a and the panel 10b respectively having the positioning mating part 22, the positioning part 11 and the positioning mating part 22 being configured in a one-to-one correspondence.

[0062] It is understandable that when cleaning and maintaining an air conditioner indoor unit, the air outlet 101 is typically opened to expose the components inside the casing 10, allowing for cleaning and maintenance of the internal structure. Therefore, this invention sets the air outlet 101 as a downward-facing outlet to facilitate downward airflow. When the panel 10b and chassis 10a of the casing 10 are respectively provided with positioning parts 11, which correspond to the positioning mating parts 22 of the grille body 21, allowing the grille 20 to be suspended from the air outlet 101, the force on both sides of the grille 20 is more even, making it less prone to deformation and detachment.

[0063] This utility model also proposes a method for disassembling an air conditioner 100, applied to the air conditioner 100 described above. The air conditioner 100 includes a housing 10, a grille 20, and fasteners 30. The housing 10 has an air vent 101 and a positioning portion 11 located on at least one circumference of the air vent 101. The grille 20 covers the air vent 101. The grille 20 includes a grille body 21 and a positioning mating portion 22 disposed on the grille body 21. The grille 20 has an assembly position where the positioning mating portion 22 and the positioning portion 11 are in a limiting fit, a transition position where the positioning mating portion 22 and the positioning portion 11 are in a positioning fit, and a separation position where the positioning mating portion 22 and the positioning portion 11 are separated. When the grille 20 is in the separation position, the grille 20 is separated from the housing 10. The method for disassembling the grille 20 includes the following steps: S100: Remove the fastener 30 from the grille 20, move the grille 20 from the assembly position to the transition position along the first direction, and then move it downward from the transition position to the separation position to separate it from the housing 10.

[0064] The first direction can be left or right. It is understood that when only one grille piece 20 is installed, and when it is assembled at the air vent 101, the fastener 30 on the grille piece 20 can be removed first. Due to the limiting fit between the positioning component and the positioning mating component, the grille piece 20 can be suspended at the air vent 101 without falling. Therefore, when the operator removes the fastener 30, the grille piece 20 will not fall. Thus, the operator does not need to support the grille piece 20 with one hand and remove the fastener 30 with the other, reducing operational difficulty and saving labor costs. After removing fastener 30, the grille 20 can be moved to the left or right, moving it from the assembly position to the transition position. The grille 20 is no longer suspended from the air vent 101, and the operator can remove it separately and move it from the transition position to the separation position, separating it from the housing 10. After the air vent 101 is opened, the grille 20 is no longer connected to the housing 10, making it convenient for the operator to inspect and maintain the air conditioning components inside the housing 10 through the air vent 101.

[0065] Optionally, the air vent 101 has a first end 101a and a second end 101b disposed opposite to each other along a first direction, and a plurality of grille members 20 are provided. Each grille member 20 has a transition position and an assembly position disposed sequentially from the first end 101a to the second end 101b. The plurality of grille members 20 includes a first grille member 20a and at least one second grille member 20b disposed sequentially from the first end 101a to the second end 101b. The steps of removing the fasteners 30 from the grille 20, moving the grille 20 along the first direction from the assembly position to the transition position, and then moving it downwards from the transition position to the separation position to separate it from the housing 10 specifically include: S101: Remove the fastener 30 from the first grille 20a, move the first grille 20a from the assembly position to the transition position along the first direction, and then move it downward from the transition position to the separation position to separate it from the housing 10. S102: Move the second grille 20b, which is close to the first grille 20a, from the assembly position to the transition position along the first direction, and then move it downward from the transition position to the separation position to separate it from the housing 10; S103: The remaining second grille pieces 20b are moved sequentially from the assembly position to the transition position and then downward from the transition position to the separation position in the order of their distribution from the first end 101a to the second end 101b, thus separating them from the housing 10.

[0066] It is understandable that when there are multiple grid components 20, the weight that the operator needs to bear when removing each grid component 20 at a time can be reduced by removing each grid component 20 in sequence, thereby further reducing the difficulty of the operator in disassembling and assembling the grid components 20 and thus further saving labor costs.

[0067] Furthermore, since the transition and assembly positions of each grille piece 20 are sequentially set from the first end 101a to the second end 101b, the disassembly and assembly directions of each grille piece 20 are the same. Each grille piece 20 is assembled by moving from the first end 101a to the second end 101b (from the transition position to the assembly position) and disassembled by moving from the second end 101b to the first end 101a (from the assembly position to the transition position). Here, only fasteners 30 are needed to fix the grille piece 20 located at the first end 101a. When the remaining grille pieces 20 move towards the first end 101a for disassembly, they will be limited by the grille piece 20 located at the first end 101a. Therefore, only a single fastener 30 is needed to install and fix multiple grille pieces 20. While splitting into multiple grille pieces 20 to reduce the difficulty of disassembling and assembling the grille pieces 20, the number of fasteners 30 is not increased, which can further save the labor cost of disassembling and assembling the grille pieces 20, thereby further reducing the inspection and maintenance cost of the air conditioner 100.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
