Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly to an air conditioner. Background Art

[0002] In order to facilitate the cleaning of the fan, some air conditioners on the market are provided with a base having a structure in which an upper air duct and a lower air duct are detachably connected. By detaching the lower air duct from the upper air duct, space is provided for disassembling the fan.

[0003] For such air conditioners, the upper air duct and the lower air duct are directly fixed by screws, and the disassembly and assembly process is difficult to operate and time-consuming and laborious. Summary of the Utility Model

[0004] The problem solved by the utility model is that the disassembly and assembly between the upper air duct and the lower air duct of the existing air conditioner is difficult, time-consuming and laborious.

[0005] To solve the above problems, the utility model provides an air conditioner, which has the characteristics of convenient, fast, time-saving and labor-saving disassembly and assembly process.

[0006] An embodiment of the utility model provides a technical solution:

[0007] An air conditioner includes an upper air duct and a lower air duct. A buckle is provided on the front surface of the bottom end of the upper air duct, and a hook is provided on the front surface of the top end of the lower air duct. The hook is snap-connected with the buckle.

[0008] For the air conditioner provided by the embodiment of the utility model, a buckle is provided on the front surface of the bottom end of the upper air duct, and a hook is provided on the front surface of the top end of the lower air duct. The hook is snap-connected with the buckle. During the assembly process, the lower air duct moves upward until the hook is snap-connected with the hook. During the disassembly process, only the snap connection between the hook and the buckle needs to be released, and the operation is convenient. Therefore, the air conditioner provided by the embodiment of the utility model has the characteristics of convenient, fast, time-saving and labor-saving disassembly and assembly process.

[0009] In an alternative embodiment, a limiting block is further provided on the front surface of the bottom end of the upper air duct. A snap interface is formed between the limiting block and the buckle, and the hook extends into the snap interface to be snap-connected with the buckle.

[0010] A snap interface is formed between the limiting block and the buckle, and the hook extends into the snap interface to be snap-connected with the buckle. The limiting block can limit the hook in the direction in which the hook exits the snap connection, ensuring the stability and reliability of the snap connection state and preventing the hook from accidentally falling off.

[0011] In an alternative embodiment, the buckle has a connection end connected to the upper air duct and a snap connection end snap-connected with the hook. From the connection end to the snap connection end, the buckle extends downward.

[0012] The buckle extends downward to ensure that the lower air duct can be smoothly clamped with the clamping end of the buckle during the upward movement under external force, reducing the operation difficulty.

[0013] In an alternative embodiment, the upper air duct is further provided with a limiting block, the limiting block is located inside the buckle, and a clamping opening with a downward opening is formed between the limiting block and the clamping end, and the hook extends into the clamping opening to be clamped with the clamping end.

[0014] A clamping opening is formed between the limiting block and the clamping end, the hook extends into the clamping opening to be clamped with the clamping end, and the limiting block can limit the hook in the direction of the hook withdrawing from the clamping, ensuring the stability and reliability of the clamping state and preventing the hook from accidentally falling off.

[0015] In an alternative embodiment, the clamping end has a first guiding sliding surface, the limiting block has a second guiding sliding surface, the first guiding sliding surface and the second guiding sliding surface form the clamping opening, and both the first guiding sliding surface and the second guiding sliding surface are convex arc surfaces.

[0016] Both the first guiding sliding surface and the second guiding sliding surface are convex arc surfaces, forming a trumpet-shaped clamping opening, so as to play a guiding and sliding role for the hook to extend into the clamping opening and ensure the smoothness of the clamping process.

[0017] In an alternative embodiment, the buckle further has a connecting seat, the connecting end is connected to the upper air duct through the connecting seat, and a thinning groove is recessed at the position where the connecting seat is connected to the outside of the connecting end.

[0018] Actually, the buckle is an elastic buckle. By recessing a thinning groove at the position where the connecting seat is connected to the outside of the connecting end, the elastic bending direction of the buckle is guided, so that the buckle bends outward during the assembly and disassembly process, that is, bends away from the hook, ensuring the smooth completion of clamping or separation.

[0019] In an alternative embodiment, the hook has a fixed end connected to the lower air duct and a mating end clamped with the buckle, and the hook extends upward from the fixed end to the mating end.

[0020] From the fixed end to the mating end, the hook extends upward, corresponding to the downward-extending buckle, ensuring that the hook can be smoothly clamped with the buckle when the lower air duct moves upward close to the upper air duct.

[0021] In an alternative embodiment, the lower air duct is further provided with a support member, the support member is located inside the hook, and the support member is connected to the position on the hook between the fixed end and the mating end.

[0022] The support member serves to strengthen the structure of the hook, thereby preventing the hook from being deformed by the gravity of the downwind duct when the hook is engaged with the buckle, thereby preventing the hook from accidentally failing the engagement structure.

[0023] In an optional embodiment, the number of the buckles and the number of the hooks are both multiple, the multiple buckles are arranged at intervals on the left and right on the upper air duct, the multiple hooks are arranged at intervals on the left and right on the lower air duct, and the multiple hooks are respectively engaged with the multiple buckles.

[0024] Multiple buckles and hooks arranged on the left and right are respectively connected to ensure the stability and reliability of the assembly structure.

[0025] In an optional embodiment, the rear side of the top end of the lower air duct is slidably matched with the rear side of the bottom end of the upper air duct, and the lower air duct is used to slide up and down relative to the upper air duct when the hook and the buckle are disengaged.

[0026] The rear side of the top end of the down duct slides with the rear side of the bottom end of the upper duct, and the front side of the top end of the down duct is clamped with the buckle on the front side of the bottom end of the upper duct through a hook. The sliding fit provides positioning for the clamping of the hook and the buckle, reducing the difficulty of operation. When the connection between the upper duct and the down duct is released, the down duct is still subject to the multi-party constraints provided by the upper duct, preventing users from applying too much restraining force.

Specific embodiments

[0041] To make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings.

[0042] Please refer to Figure 1 and Figure 2 , Figure 1 as shown in Figure 2 is a schematic structural view of the air conditioner 100 provided in this embodiment,

[0043] The air conditioner 100 provided in this embodiment includes a base and a middle frame assembly 200, and the middle frame assembly 200 covers the base. The base adopts a split - type structure and is composed of a detachable upper air duct 110 and a lower air duct 120. Components such as a fan 130 and an air - sweeping blade 140 are installed on the upper air duct 110. After the lower air duct 120 is assembled with the upper air duct 110, a air - supply channel is formed, and the fan 130 and the air - sweeping blade 140 are accommodated in the air - supply channel.

[0044] In practical applications, when the air conditioner 100 is operating normally, the upper air duct 110 and the lower air duct 120 are in a connected state. When it is necessary to clean or maintain components such as the blower 130 and the swing blade 140 in the air conditioner 100, the lower air duct 120 is detached from the upper air duct 110, thereby providing space for the disassembly and assembly of components such as the blower 130 and the swing blade 140.

[0045] In order to reduce the difficulty of disassembly and assembly and improve the disassembly and assembly efficiency, in this embodiment, the lower air duct 120 is slidably engaged with the upper air duct 110. When the connection between the lower air duct 120 and the upper air duct 110 is released, the lower air duct 120 can slide relative to the upper air duct 110. It can be understood that the release of the connection between the lower air duct 120 and the upper air duct 110 means the release of the mutually locked state between them.

[0046] Please refer to Figure 3 , Figure 4 and Figure 5 , Figure 3 The schematic diagram of the connection structure between the upper air duct 110 and the middle frame assembly 200 is shown in Figure 4 as Figure 3 the enlarged schematic diagram of area A in Figure 5 shown in Figure 3 the enlarged schematic diagram of area B in

[0047] In this embodiment, a chute 111 is provided at the bottom end of the upper air duct 110, and the top end of the lower air duct 120 extends into the chute 111 and is slidably engaged with the chute 111 for sliding into or out of the upper air duct 110 along the chute 111.

[0048] Actually, from one end to the other end of the chute 111, the entire chute 111 extends in the vertical direction. In practical applications, the upper air duct 110 is installed on the wall surface, and one end of the chute 111 is open at the bottom end of the upper air duct 110. During the process of the lower air duct 120 moving upward close to the upper air duct 110, it is slidably engaged with the chute 111 through the opening of the chute 111. During the further upward movement of the lower air duct 120, it gradually slides into the upper air duct 110 along the chute 111 of the upper air duct 110 until it establishes a connection with the upper air duct 110 and completes the locking.

[0049] It can be seen that due to the sliding engagement between the lower air duct 120 and the upper air duct 110, during the assembly process, the process of the lower air duct 120 sliding along the chute 111 can automatically complete the positioning of the connection between the two, reducing the operation difficulty of establishing the connection. Moreover, during the disassembly and assembly process of the lower air duct 120, it slides relative to the upper air duct 110 and can be restricted in multiple directions other than the sliding direction. The movement process of the lower air duct 120 is stable and controllable, saving time and effort.

[0050] Please refer to Figure 6 and Figure 7 ,Figure 6 The figure shows a partial structural schematic diagram of the lower air duct 120. Figure 7 As shown in Figure 6 an enlarged schematic diagram of area C in

[0051] In order to ensure the stability of the sliding process of the lower air duct 120, in this embodiment, the number of the sliding grooves 111 is two, and the two sliding grooves 111 are oppositely arranged on the left side wall 118 and the right side wall 119 at the bottom end of the upper air duct 110. Guide sliders 121 are arranged at both the left and right ends of the lower air duct 120, and the two guide sliders 121 are respectively in sliding fit with the two sliding grooves 111.

[0052] The bottom wall of one of the sliding grooves 111 is the inner surface of the left side wall 118 of the upper air duct 110, and the bottom wall of the other sliding groove 111 is the inner surface of the right side wall 119 of the upper air duct 110. The two sliding grooves 111 are opposite to each other and form an integral sliding track for the lower air duct 120 to slide in or out. It can be understood that in the assembled state, the two guide sliders 121 at both the left and right ends of the lower air duct 120 are respectively located in the left and right sliding grooves 111 of the upper air duct 110, which is equivalent to the lower air duct 120 being between the two sliding grooves 111, forming a drawer-type fitting structure.

[0053] During the process of pushing the lower air duct 120 upward, the two guide sliders 121 slide upward synchronously in the two sliding grooves 111 respectively, and the lower air duct 120 gradually enters the interior of the upper air duct 110 to complete the assembly. When it is necessary to disassemble the lower air duct 120 in the assembled state, first release the connection between the lower air duct 120 and the upper air duct 110, and then drive the lower air duct 120 to slide downward along the two sliding grooves 111 until the two guide sliders 121 withdraw from the two sliding grooves 111.

[0054] In this embodiment, the extending track of the sliding groove 111 is arc-shaped, actually a concave arc shape. During the process of sliding the lower air duct 120 into the upper air duct 110, the lower air duct 120 slides backward and upward along the concave arc track. During the process of sliding the lower air duct 120 out of the upper air duct 110, the lower air duct 120 slides forward and downward along the concave arc track.

[0055] Since the track of the sliding groove 111 is arc-shaped, it ensures a sufficient sliding stroke of the lower air duct 120, and also avoids the situation that the lower air duct 120 is overly affected by gravity during vertical sliding or has too large a sliding resistance in the horizontal direction, ensuring a smooth and stable sliding process, making the disassembly and assembly process more convenient, fast, time-saving and labor-saving.

[0056] It should be noted that the directions in this embodiment are defined based on the state where the air conditioner 100 is installed on the wall. When the air conditioner 100 is installed on the wall, the direction towards the ground is the lower direction, the direction away from the ground is the upper direction, the direction parallel to the ground and the wall is the left - right direction, the direction close to the wall is the rear direction, and the direction away from the wall is the front direction.

[0057] In order to reduce the weight of the lower air duct 120 and further reduce the difficulty of disassembly and assembly, in this embodiment, weight - reducing grooves 1211 are recessed on the two side walls of the two guide sliders 121 facing away from each other. It can be understood that the weight - reducing grooves 1211 are formed by removing part of the structure on the surface of the guide sliders 121. The weight of the guide sliders 121 is reduced, so that the weight of the lower air duct 120 is reduced, achieving the effect of more labor - saving during the disassembly and assembly process.

[0058] Please continue to refer to Figure 4 , in this embodiment, the chute 111 has a convex - arc upper side wall 112 and a concave - arc lower side wall. The upper side wall 112 and the lower side wall are arranged opposite to each other. Both guide sliders 121 have concave - arc upper guide walls 1212, and the upper guide walls 1212 are opposite to the upper side wall 112.

[0059] The guide slider 121 slides between the upper side wall 112 and the lower side wall. The lower side wall supports the guide slider 121. Through the cooperation between the convex - arc upper side wall 112 provided on the chute 111 and the concave - arc upper guide wall 1212 provided on the guide slider 121, the arc - shaped limit of the upper guide wall 1212 is realized, ensuring the smoothness of the contact surface during the sliding process, and ensuring that when the sliding is in place, the upper side wall 112 can constrain and fix the guide slider 121 to prevent the lower air duct 120 from falling.

[0060] In this embodiment, the upper air duct 110 has a supporting inner wall 113, and the supporting inner wall 113 is concave - arc - shaped and serves as the common lower side wall of the two chutes 111. The lower air duct 120 has a mating outer wall 122 corresponding to the supporting inner wall 113, and the mating outer wall 122 is convex - arc - shaped. The two guide sliders 121 are respectively arranged at the left and right ends of the mating outer wall 122.

[0061] It can be understood that during the process of the lower air duct 120 sliding relative to the upper air duct 110, the convex - arc - shaped mating outer wall 122 on the outer surface of the lower air duct 120 fits and slides relative to the concave - arc - shaped supporting inner wall 113 inside the upper air duct 110. The supporting inner wall 113 plays a role in supporting and guiding the sliding process of the lower air duct 120. Since the supporting inner part serves as the common lower side wall of the two chutes 111, it ensures that the sliding tracks of the two guide sliders 121 are the same as and synchronous with the sliding track of the mating outer wall 122, ensuring the smoothness of the sliding process.

[0062] Please continue to refer toFigure 5 In addition, the upper air duct 110 further includes an upper flow guiding wall 114, which is located at the ends of the two sliding grooves 111 and protrudes from the surface of the supporting inner wall 113 to form a stepped structure. The lower air duct 120 further includes a lower flow guiding wall 123, and the lower flow guiding wall 123 and the mating outer wall 122 are respectively located on the inner and outer sides of the lower air duct 120, and the lower flow guiding wall 123 is aligned with the upper flow guiding wall 114.

[0063] The stepped structure formed by the upper flow guiding wall 114 and the supporting inner wall 113 is engaged with the structure where the lower air duct 120 extends into the upper air duct 110. That is, the mating outer wall 122 on the outer surface of the lower air duct 120 is in contact with the supporting inner wall 113 of the upper air duct 110, and the lower flow guiding wall 123 on the inner surface of the lower air duct 120 is aligned with the upper flow guiding wall 114 on the inner surface of the upper air duct 110. When the mating outer wall 122 slides in place on the supporting inner wall 113, the lower flow guiding wall 123 is aligned with the upper flow guiding wall 114, forming a complete and smooth inner wall of the air duct, thus realizing smooth air guiding for the air outlet of the air conditioner 100.

[0064] Please refer to Figure 8 and Figure 9 , Figure 8 which shows a schematic diagram of the connection structure between the upper air duct 110 and the lower air duct 120, Figure 9 and Figure 8 shows an enlarged schematic diagram of area D in

[0065] For the detachable connection method between the upper air duct 110 and the lower air duct 120, in this embodiment, a buckle 115 is provided on the front side surface of the bottom end of the upper air duct 110, and a hook 124 is provided on the front side surface of the top end of the lower air duct 120, and the hook 124 is snap-fitted with the buckle 115.

[0066] Actually, the structure at the rear side of the top end of the lower air duct 120 is in sliding fit with the two sliding grooves 111 on the upper air duct 110. During the actual assembly process, first, the structure at the rear side of the top end of the lower air duct 120 is aligned and extended between the two sliding grooves 111, so that the two guide sliders 121 at the left and right ends of the lower air duct 120 respectively enter the two sliding grooves 111. Then, the lower air duct 120 is continuously pushed upward, and the two guide sliders 121 slide upward along the two sliding grooves 111.

[0067] During this process, the hook 124 provided on the front side surface of the top end of the lower air duct 120 is aligned with and gradually approaches the buckle 115 provided on the front side surface of the upper air duct 110. When the lower air duct 120 slides to just fit with the stepped structure on the upper air duct 110, the lower flow guiding wall 123 of the lower air duct 120 is aligned with the upper flow guiding wall 114 of the upper air duct 110, and the hook 124 is snap-fitted with the buckle 115.

[0068] It can be understood that the engagement of the hook 124 with the buckle 115 realizes the connection and locking of the lower air duct 120 and the upper air duct 110, ensuring that the lower air duct 120 does not slide relative to the upper air duct 110 without external force, guaranteeing the stability of the assembly structure and preventing the accidental dropping of the lower air duct 120.

[0069] To ensure the stable and reliable locking effect, in this embodiment, the number of buckles 115 and hooks 124 is multiple. The multiple buckles 115 are arranged at intervals left and right on the upper air duct 110, and the multiple hooks 124 are arranged at intervals left and right on the lower air duct 120. The multiple hooks 124 are respectively engaged with the multiple buckles 115.

[0070] Please refer to Figure 10 and Figure 11 , Figure 10 as shown in Figure 8 the exploded structure schematic diagram of Figure 11 as shown in Figure 10 the enlarged schematic diagram of area E in

[0071] In this embodiment, a limiting block 116 is further provided on the front side surface at the bottom end of the upper air duct 110. The limiting block 116 is located inside the buckle 115, and a clamping interface 117 is formed between the limiting block 116 and the buckle 115. The hook 124 extends into the clamping interface 117 and is engaged with the buckle 115.

[0072] In fact, the buckle 115 in this embodiment is an elastic member with a certain elastic deformation ability. The hook 124 is engaged with the buckle 115 by extending into the clamping interface 117. The hook 124 is located at the rear side of the buckle 115 and in front of the limiting block 116. The limiting block 116 restricts the movement of the hook 124 in the rear direction away from the buckle 115, playing a role in preventing the hook 124 from disengaging from the buckle 115.

[0073] The buckle 115 has a connection end 1151 connected to the upper air duct 110 and a clamping end 1152 engaged with the hook 124. From the connection end 1151 to the clamping end 1152, the buckle 115 extends downward. That is, the buckle 115 is a cantilever structure with its connection end 1151 fixed and the clamping end 1152 suspended. The clamping end 1152 can be vertically oriented or inclined downward.

[0074] A clamping interface 117 with a downward opening is formed between the limiting block 116 and the clamping end 1152, and the hook 124 extends into the clamping interface 117 to be clamped with the clamping end 1152. During the upward sliding of the lower air duct 120 along the sliding groove 111, the hook 124 moves upward synchronously. When the hook 124 moves to the clamping interface 117, the hook 124 squeezes the clamping end 1152 in a direction away from the limiting block 116, causing the buckle 115 to elastically bend until the hook 124 extends into the clamping interface 117, and then the buckle 115 restores its deformation, and the clamping end 1152 and the hook 124 complete the clamping.

[0075] In this embodiment, in order to ensure the smooth completion of the clamping process, in this embodiment, the clamping end 1152 has a first guiding sliding surface 1153, the limiting block 116 has a second guiding sliding surface 1161, the first guiding sliding surface 1153 and the second guiding sliding surface 1161 form the clamping interface 117, and both the first guiding sliding surface 1153 and the second guiding sliding surface 1161 are convex arc surfaces.

[0076] It can be understood that both the first guiding sliding surface 1153 of the clamping end 1152 and the second guiding sliding surface 1161 of the limiting block 116 are convex arc surfaces, forming a horn-shaped clamping interface 117. The first guiding sliding surface 1153 and the second guiding sliding surface 1161 play a role in guiding the hook 124. During the process of the hook 124 extending into the clamping interface 117, the front sides of both sides of the hook 124 slide on the first guiding sliding surface 1153 and the second guiding sliding surface 1161, and the buckle 115 is pushed to bend and deform during this process.

[0077] In this embodiment, the buckle 115 further has a connecting seat 1154. The connecting end 1151 is connected to the upper air duct 110 through the connecting seat 1154, and a thinning groove 1155 is recessed at the position where the connecting seat 1154 is connected to the outside of the connecting end 1151.

[0078] By recessing the thinning groove 1155 at the position where the connecting seat 1154 is connected to the outside of the connecting end 1151, the elastic bending direction of the buckle 115 is guided, so that the buckle 115 bends outward during the assembly and disassembly processes, that is, bends in a direction away from the hook 124, ensuring that the hook-shaped part at the end of the hook 124 can smoothly cross the clamping end 1152 of the buckle 115 and ensuring the smooth completion of clamping or separation.

[0079] Please refer to Figure 12 , Figure 12 for Figure 10 the enlarged schematic diagram of area F in

[0080] The hook 124 has a fixed end 1241 connected to the lower air duct 120 and a mating end 1242 clamped with the buckle 115. From the fixed end 1241 to the mating end 1242, the hook 124 extends upward.

[0081] Similarly, the upward extension of the hook 124 can be vertically upward or inclined upward. During the process of the lower air duct 120 sliding upward along the sliding groove 111, the mating end 1242 of the hook 124 gradually approaches the engaging end 1152 of the hook 124 upward. It can be understood that hook-shaped portions are provided on the front side of the mating end 1242 of the hook 124 and the rear side of the engaging end 1152 of the buckle 115. During the process of the sub-mating end 1242 extending into the engaging opening 117, the hook-shaped portion of the mating end 1242 presses the engaging end 1152, causing the buckle 115 to bend forward until the hook-shaped portion of the mating end 1242 passes over the hook-shaped portion of the engaging end 1152. The engaging end 1152 is reset due to the loss of the abutting action of the mating end 1242, and the two hook-shaped portions of the two are engaged.

[0082] In the engaged state, the engaging end 1152 is subjected to a downward force, which is in the same direction as the extending direction of the buckle 115. The buckle 115 will not undergo elastic deformation, and the hook 124 is also blocked by the limiting block 116, ensuring the stability of the engaging structure and realizing the reliable locking of the lower air duct 120 on the upper air duct 110.

[0083] In order to improve the strength of the hook 124 and thus improve the reliability of the engaging structure, in this embodiment, the lower air duct 120 is further provided with a support member 125. The support member 125 is located inside the hook 124, and the support member 125 is connected to a position on the hook 124 between the fixed end 1241 and the mating end 1242. It can be understood that the support member 125 plays a role in supporting and strengthening the hook 124, preventing the hook 124 from deforming and causing the failure of the engaging structure.

[0084] When it is necessary to disassemble the lower air duct 120, only a force needs to be applied to the buckle 115 to cause the buckle 115 to bend outward. The engaged state between the hook 124 and the buckle 115 can be released, and the mating end 1242 of the hook 124 can exit the engaging opening 117. It can be understood that during the process of the mating end 1242 exiting the engaging opening 117, the lower air duct 120 slides downward along the sliding groove 111, and then the lower air duct 120 continues to slide until it disengages from the sliding groove 111, and the disassembly of the lower air duct 120 can be completed.

[0085] After the disassembly of the lower air duct 120 is completed, the fan 130 and the sweeping blades 140 in the air supply channel are exposed to the environment, and the user can disassemble the fan 130 and the sweeping blades 140, so as to conveniently and quickly complete cleaning, maintenance and other processes.

[0086] In summary, the air conditioner 100 provided in this embodiment has the characteristics of convenient, fast, time-saving and labor-saving disassembly and assembly processes.
