Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and more 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 structure in which the upper air duct and the 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, there is a lack of a matching structure for guiding disassembly and assembly between the upper air duct and the lower air duct. During the disassembly and assembly process, problems such as misalignment and jamming are likely to occur between the lower air duct and the upper air duct, making the disassembly and assembly difficult, 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 a detachable upper air duct and a lower air duct. Sliding grooves are provided on the left and right side walls at the bottom end of the upper air duct, and guide sliders are provided at the left and right ends of the lower air duct. The two guide sliders are respectively in sliding fit with the two sliding grooves.

[0008] For the air conditioner provided by the embodiment of the utility model, the upper air duct and the lower air duct are in sliding fit. When the connection between the upper air duct and the lower air duct is released, the lower air duct and the upper air duct are in sliding fit. Only a force in the sliding direction needs to be applied to the lower air duct, and the other directions are restricted by the upper air duct. Before establishing the connection between the lower air duct and the upper air duct, the lower air duct and the upper air duct are in sliding fit and slide into place, realizing automatic positioning of the connection relationship and reducing the operation difficulty of establishing the connection. 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] The top end of the lower air duct extends into the sliding groove and slides into or out of the upper air duct along the sliding groove. During the disassembly and assembly process, the user stands on the ground and the air conditioner is installed on the wall. The user only needs to apply a force in the vertical direction to the lower air duct, which is convenient to operate and time-saving and labor-saving.

[0010] By the sliding fit between the guide sliders respectively provided at the left and right ends of the lower air duct and the sliding grooves respectively provided on the left and right side walls of the upper air duct, stable horizontal limiting of the lower air duct is realized, and smooth sliding of both ends is ensured, improving the smoothness of the disassembly and assembly process.

[0011] In an alternative embodiment, the extending trajectory of the sliding groove is arc-shaped.

[0012] The extending trajectory of the sliding groove is arc-shaped, which is adapted to the arc-shaped structure of the air duct, ensuring that the overall structure of the air duct is smooth and complete when the assembly is completed. Moreover, the arc-shaped sliding trajectory is more conducive to sliding operation.

[0013] In an alternative embodiment, at least one of the guide sliders is recessed with a weight-reducing groove.

[0014] By providing a weight-reducing groove on the guide slider, the overall weight of the lower air duct is reduced, thereby further reducing the difficulty of disassembly and assembly.

[0015] In an alternative embodiment, the weight-reducing grooves are recessed on the two side walls of the two guide sliders facing away from each other.

[0016] The weight-reducing grooves are provided on the two side walls of the two guide sliders facing away from each other. On the one hand, it can significantly reduce the weight of the lower air duct, and on the other hand, it can ensure that the sliding of the two guide sliders in the two sliding grooves is not affected.

[0017] In an alternative embodiment, both of the two sliding grooves have convex arc-shaped upper side walls, and both of the two guide sliders have concave arc-shaped upper guide walls, and the upper guide walls are opposite to the upper side walls.

[0018] Through the cooperation between the convex arc-shaped upper side walls provided on the sliding grooves and the concave arc-shaped upper guide walls provided on the guide sliders, the arc-shaped limit of the upper guide walls is realized, ensuring the smoothness of the contact surface during the sliding process, and ensuring that the upper side walls can constrain and fix the guide sliders when the sliding reaches the end, preventing the lower air duct from falling off.

[0019] In an alternative embodiment, the upper air duct has a supporting inner wall, and the supporting inner wall is concave arc-shaped and serves as the common lower side wall of the two sliding grooves;

[0020] The lower air duct has a mating outer wall corresponding to the supporting inner wall, the mating outer wall is convex arc-shaped, and the two guide sliders are respectively arranged at the left and right ends of the mating outer wall.

[0021] The concave arc-shaped lower side wall serves as the common lower side wall of the left and right two sliding grooves, realizing the support of the lower air duct and providing an arc-shaped sliding trajectory. The convex arc-shaped mating outer wall of the lower air duct is attached to and slides along the lower side wall, ensuring that the lower air duct is reliably supported during the sliding process and ensuring the smoothness of the sliding process.

[0022] In an alternative embodiment, the upper air duct further has an upper diversion wall, and the upper diversion wall is at the end of the two sliding grooves and protrudes from the surface of the supporting inner wall to form a step structure;

[0023] The lower air duct further has a lower guiding wall. The lower guiding wall and the mating outer wall are respectively on the inner and outer sides of the lower air duct, and the lower guiding wall is aligned with the upper guiding wall.

[0024] When the mating outer wall slides into place on the supporting inner wall, the lower guiding wall is aligned with the upper guiding wall, forming a complete and smooth inner wall of the air duct, so as to smoothly guide the air blown out by the air conditioner.

[0025] In an alternative embodiment, a blower and a sweeping blade are installed in the upper air duct. The upper air duct and the lower air duct together form an air supply channel, and the blower and the sweeping blade are accommodated in the air supply channel.

[0026] The blower and the sweeping blade are installed in the upper air duct and are in the air supply channel. After the lower air duct is detached, the blower and the sweeping blade are exposed to the environment, enabling quick disassembly and assembly of the two, and reducing the difficulty of cleaning and maintenance.

Detailed implementation manners

[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 the structural schematic diagram of the air conditioner 100 provided in this embodiment, Figure 2 As shown in the exploded structural schematic diagram of the air conditioner 100.

[0043] The air conditioner 100 provided in this embodiment includes a base and a middle frame assembly 200. 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 a 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, an air supply channel is formed, and the fan 130 and the 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 fan 130 and the sweeping 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 fan 130 and the sweeping blade 140.

[0045] In order to reduce the difficulty of disassembly and assembly and improve the efficiency of disassembly and assembly, 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 the two.

[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 which is Figure 3 the enlarged schematic diagram of area A in Figure 5 and Figure 3 the enlarged schematic diagram of area B in

[0047] In this embodiment, a chute 111 is opened 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 whole 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 opened 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 a connection with the upper air duct 110 is established and locked.

[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 partial structural schematic diagram of the lower air duct 120 is shown in Figure 7 which is Figure 6 the enlarged schematic diagram of area C in

[0051] 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 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, and the lower air duct 120 gradually enters 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 exit the two sliding grooves 111.

[0054] In this embodiment, the extending track of the sliding groove 111 is arc-shaped, actually a concave arc. 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 affected too much by gravity during vertical sliding or has too much sliding resistance during horizontal sliding, 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 orientation in this embodiment is 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 of the air conditioner 100 is the lower side, the direction away from the ground is the upper side, the direction parallel to the ground and the wall is the left and right direction, the direction close to the wall is the rear, and the direction away from the wall is the front.

[0057] In order to reduce the weight of the lower air duct 120, thereby further reducing the difficulty of disassembly and assembly, in this embodiment, weight reduction grooves 1211 are recessed on two side walls of the two guide sliders 121 facing away from each other. It can be understood that the weight reduction 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 , the chute 111 in this embodiment has a convex arc-shaped upper side wall 112 and a concave arc-shaped lower side wall, the upper side wall 112 and the lower side wall are arranged opposite to each other, and both guide sliders 121 have concave arc-shaped 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, and the lower side wall supports the guide slider 121. Through the cooperation between the convex arc-shaped upper side wall 112 provided on the chute 111 and the concave arc-shaped 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 reaches the position, the upper side wall 112 can restrain 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, the mating outer wall 122 is convex arc-shaped, and 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 sliding process of the lower air duct 120 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 in the upper air duct 110, and the supporting inner wall 113 plays a role of support and guidance in 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 trajectories of the two guide sliders 121 are the same and synchronous with the sliding trajectory of the mating outer wall 122, ensuring the smoothness of the sliding process.

[0062] Please continue to refer to Figure 5 , the upper air duct 110 further has an upper diversion wall 114, the upper diversion wall 114 is at the end of the two chutes 111 and protrudes from the surface of the supporting inner wall 113 to form a stepped structure. The lower air duct 120 further has a lower diversion wall 123, the lower diversion wall 123 and the mating outer wall 122 are respectively on the inner and outer sides of the lower air duct 120, and the lower diversion wall 123 is aligned with the upper diversion wall 114.

[0063] The stepped structure formed by the upper guide wall 114 and the supporting inner wall 113 is fitted with the structure of the lower air duct 120 extending 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 guide wall 123 on the inner surface of the lower air duct 120 is aligned with the upper guide wall 114 on the inner surface of the upper air duct 110. When the mating outer wall 122 slides into place on the supporting inner wall 113, the lower guide wall 123 is aligned with the upper guide wall 114, forming a complete and smooth inner wall of the air duct, achieving smooth diversion of the air discharged from the air conditioner 100.

[0064] Please refer to Figure 8 and Figure 9 , Figure 8 Figure 10 shows a schematic diagram of the connection structure between the upper air duct 110 and the lower air duct 120. Figure 9 As shown in Figure 8 Figure 11, the enlarged schematic diagram of area D in Figure 10.

[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. The hook 124 is snap-fitted with the buckle 115.

[0066] Actually, the rear side structure of the top end of the lower air duct 120 is in sliding fit with the two chutes 111 on the upper air duct 110. During the actual assembly process, first align the rear side structure of the top end of the lower air duct 120 and extend it between the two chutes 111, so that the two guide sliders 121 at the left and right ends of the lower air duct 120 respectively enter the two chutes 111. Then continue to push the lower air duct 120 upward, and the two guide sliders 121 slide upward along the two chutes 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 guide wall 123 of the lower air duct 120 is aligned with the upper guide 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 snap-fitting of the hook 124 and 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 will not slide relative to the upper air duct 110 without external force, ensuring the stability of the assembly structure and preventing the lower air duct 120 from accidentally falling off.

[0069] To ensure the stable and reliable locking effect, in this embodiment, the number of the buckles 115 and the 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 structural 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. 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 clamped with the buckle 115.

[0072] Actually, the buckle 115 in this embodiment is an elastic member and has a certain elastic deformation ability. The hook 124 is clamped 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 at the front side of the limiting block 116. The limiting block 116 restricts the hook 124 from moving in the rear side direction away from the buckle 115, and plays 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 clamped 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, its connection end 1151 is fixed, the clamping end 1152 is suspended, and the clamping end 1152 can face vertically or obliquely downward.

[0074] A clamping interface 117 with an opening downward is formed between the limiting block 116 and the clamping end 1152. The hook 124 extends into the clamping interface 117 and is clamped with the clamping end 1152. During the process of the lower air duct 120 sliding upward along the chute 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 the direction away from the limiting block 116, causing the buckle 115 to bend elastically until the hook 124 extends into the clamping interface 117, and then the buckle 115 resumes 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, and 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 a clamping port 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 trumpet-shaped clamping port 117. The first guiding sliding surface 1153 and the second guiding sliding surface 1161 play a role in guiding the clamping hook 124. During the process of the clamping hook 124 extending into the clamping port 117, the two sides in front of the clamping hook 124 slide on the first guiding sliding surface 1153 and the second guiding sliding surface 1161. During this process, the clamping buckle 115 is pushed to bend and deform.

[0077] In this embodiment, the clamping 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. 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 clamping buckle 115 is guided, so that the clamping buckle 115 bends outward during the assembly and disassembly processes, that is, bends away from the clamping hook 124, ensuring that the hook-shaped part at the end of the clamping hook 124 can smoothly cross the clamping end 1152 of the clamping 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 the F area in

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

[0081] Similarly, the upward extension of the catch 124 can be vertically upward or inclined upward. During the upward sliding of the lower air duct 120 along the chute 111, the mating end 1242 of the catch 124 gradually approaches the engaging end 1152 of the catch 124 upward. It can be understood that hook-shaped portions are provided on the front side of the mating end 1242 of the catch 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 to cause 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 without 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 in the same direction as the extending direction of the buckle 115, and the buckle 115 does not undergo elastic deformation. Moreover, the catch 124 is blocked by the limiting block 116, ensuring the stability of the engaging structure and achieving reliable locking of the lower air duct 120 on the upper air duct 110.

[0083] In order to improve the strength of the catch 124 and thus enhance 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 catch 124 and is connected to the position of the catch 124 between the fixed end 1241 and the mating end 1242. It can be understood that the support member 125 supports and strengthens the catch 124, preventing the catch 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, and the engaged state between the catch 124 and the buckle 115 can be released, and the mating end 1242 of the catch 124 can withdraw from the engaging opening 117. It can be understood that during the process of the mating end 1242 withdrawing from the engaging opening 117, the lower air duct 120 slides downward along the chute 111, and then the lower air duct 120 continues to slide until it disengages from the chute 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 blade 140 in the air supply channel are exposed to the environment, and the user can disassemble the fan 130 and the sweeping blade 140, thus conveniently and quickly completing 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.

[0087] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the scope defined by the claims.
