Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] At present, some air conditioners on the market have the downwind duct mounted on the base in a detachable manner in order to facilitate the disassembly and assembly of the crossflow fan blades and the sweeping blades.

[0003] This type of air conditioner usually uses screws as locking parts between the downwind duct and the base. Before disassembling the downwind duct, the screws need to be unscrewed, and when assembling the downwind duct, the screws need to be tightened again. The operation is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] The utility model solves the problem that the disassembly and assembly operation of the downwind duct of the existing air conditioner is tedious and complicated, which is time-consuming and labor-intensive.

[0005] In order to solve the above problems, the utility model provides an air conditioner, which can complete the disassembly and assembly of the downwind duct conveniently and quickly, saving time and labor.

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

[0007] An air conditioner comprises a base, a downwind duct, and a locking mechanism, wherein the base has a locking portion; the locking mechanism comprises a handle and a locking member connected to each other, at least one of the handle and the locking member being movably connected to the downwind duct;

[0008] The locking piece cooperates with the locking portion to lock the downwind duct, and the handle is used to drive the locking piece to move to disengage from the locking portion when subjected to a downward pressing force, so as to release the lock on the downwind duct.

[0009] The air conditioner provided in the embodiment of the present invention is provided with a locking mechanism on the downwind duct, which includes a handle and a locking member. The locking member cooperates with the locking portion on the base to lock the downwind duct on the base. When the downwind duct needs to be removed, the handle is pressed downward, which is convenient and quick to operate. Therefore, the air conditioner provided in the embodiment of the present invention can conveniently and quickly complete the disassembly and assembly of the downwind duct, saving time and effort.

[0010] In an optional embodiment, the locking member and the handle are slidably engaged with each other, and both are slidably engaged with the downwind duct respectively;

[0011] The handle is used to slide downward on the downwind duct when subjected to a pressing force to push the locking member to slide in a first direction until it is disengaged from the locking portion, and the first direction forms an angle with the sliding direction of the downwind duct.

[0012] The handle slides downward when subjected to a downward pressing force, thereby pushing the locking member to slide until it is disengaged from the locking portion, thereby achieving rapid unlocking of the downwind duct.

[0013] In an optional embodiment, the handle has a pushing bevel, and the locking piece has a mating bevel. The pushing bevel and the mating bevel are slidably fitted together, and both are inclined relative to the vertical direction and the first direction. The pushing bevel is used to push the locking piece to slide through the mating bevel when the handle slides downward.

[0014] As the handle slides downward, the push inclined surface and the matching inclined surface slide relative to each other, thereby pushing the locking member to slide in a first direction different from the movement direction of the handle, thereby disengaging from the locking portion and unlocking the downwind duct.

[0015] In an optional embodiment, a limiting groove is concavely provided on the pushing inclined surface, and the limiting groove has an upper groove wall and a lower groove wall arranged opposite to each other in the vertical direction;

[0016] A limiting protrusion is convexly provided on the matching inclined surface, and the limiting protrusion extends into the limiting groove and is used for moving between the upper groove wall and the lower groove wall.

[0017] When the handle slides downward until the upper wall of the limit groove abuts against the limit protrusion, the stop locking piece slides excessively in the unlocking direction; when the locking piece slides back to the extreme position under the action of external force, it drives the handle to return to its position, and the lower wall of the limit groove abuts against the limit protrusion to prevent the handle from returning to its original position.

[0018] In an optional embodiment, the downwind duct has a guide slide plate arranged obliquely in the vertical direction, and the handle also has a guide slide inclined surface, which is slidably fitted with the guide slide plate. The guide slide plate is used to guide the handle to slide downward through the guide slide inclined surface when the handle is subjected to a downward pressing force.

[0019] The guide slide guides the sliding of the downwind duct, ensuring that the unlocking movement is precise and smooth.

[0020] In an optional embodiment, the locking member has an assembly groove, the mating bevel is located on one side wall of the assembly groove, the guide slide extends into the assembly groove and is arranged opposite to the mating bevel in the first direction, the handle extends into the assembly groove, and the guide slide bevel and the pushing bevel are respectively located on opposite sides of the handle in the first direction.

[0021] The locking member cooperates with the handle through its assembly groove, which on the one hand saves the lower air duct space, and on the other hand ensures that the sliding cooperation relationship between the handle and the locking member is stable and reliable.

[0022] In an optional embodiment, the downwind duct has two mounting walls, and the two mounting walls are penetrated by guide sliding holes coaxially arranged in the first direction;

[0023] The locking member includes a main body and a sliding rod that are connected to each other. The main body slides with the handle. The two ends of the sliding rod can be slidably mounted in the guide holes on the two mounting walls. The main body is located between the two mounting walls and cooperates with the locking portion.

[0024] When the main body is pushed by the handle, the slide rod is driven to slide in the two guide holes. The two guide holes support and guide the slide rod to ensure a smooth movement process.

[0025] In an optional embodiment, the locking member further includes an elastic return member, which is sleeved on one end of the sliding rod, and the opposite ends of the elastic return member are respectively abutted against the main body and one of the mounting walls, and is used to drive the main body to return and slide in a second direction after the pressing force acting on the handle is withdrawn, so as to push the handle to return and slide upward, and the second direction is opposite to the first direction.

[0026] After the force applied to the handle is removed, the elastic return element releases its elastic potential energy and expands, pushing the locking element back to engage with the locking portion on the base, thereby re-locking the downwind duct. During this process, the locking element pushes the handle back to its original position, ready for the next unlocking.

[0027] In an optional embodiment, the locking portion is provided with a hook, and the locking member has a buckle, and the buckle is engaged with the hook.

[0028] The cooperation between the locking piece and the locking portion is the engagement of the buckle and the hook. Driven by the handle, the buckle and the hook are disengaged, thereby completing the unlocking of the downwind duct.

[0029] In an optional embodiment, there are two locking parts and two locking mechanisms, the two locking parts are respectively located at the left and right ends of the base, the two locking mechanisms are respectively arranged at the left and right ends of the downwind duct, and the two locking members corresponding to the two locking mechanisms cooperate with the two locking parts respectively.

[0030] The two locking mechanisms are respectively located at the left and right ends of the downwind duct, thereby achieving reliable locking of the downwind duct. During the disassembly and assembly process, the user holds the left and right ends of the downwind duct with both hands to achieve stable support for the downwind duct, ensuring the stability and reliability of the disassembly and assembly process.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a structural diagram of an air conditioner 100 provided in this embodiment. Figure 2 FIG. 1 is a schematic diagram of the exploded structure of the air conditioner 100 .

[0039] The air conditioner 100 provided in this embodiment includes a base 110, a downwind duct 120 and a middle frame 140. The downwind duct 120 and the base 110 are detachably connected to form an air duct structure. The air duct structure is provided with structures such as cross-flow blades and sweeping blades 150. The middle frame 140 is covered on the base 110 and covers the downwind duct 120, and the middle frame 140 is hinged to the base 110.

[0040] In actual application, when it is necessary to clean the cross-flow blades, sweeping blades 150, etc. in the air duct structure, the middle frame 140 can be lifted up first to expose the downwind duct 120, and then the downwind duct 120 can be removed from the base 110, thereby exposing the cross-flow blades and sweeping blades 150 and other structures in the air duct structure to the environment, making it convenient for users to clean.

[0041] To lock the down duct 120 on the base 110, the air conditioner 100 provided in this embodiment further includes a locking mechanism 130. The base 110 has a locking portion 111. The locking mechanism 130 includes a handle 131 and a locking member 132 that are connected to each other. At least one of the handle 131 and the locking member 132 is movably connected to the down duct 120. The locking member 132 cooperates with the locking portion 111 to lock the down duct 120. When the handle 131 is subjected to a downward pressing force, it is configured to drive the locking member 132 to move until it disengages from the locking portion 111, thereby releasing the lock on the down duct 120.

[0042] It is understood that when the down duct 120 is assembled in place on the base 110, the locking member 132 of the locking mechanism 130 cooperates with the locking portion 111 on the base 110, thereby locking the down duct 120 on the base 110. When the down duct 120 needs to be removed, a downward pressing force is applied to the handle 131 of the locking mechanism 130, causing the handle 131 to move on the down duct 120, driving the locking member 132 to move until it cooperates with the locking portion 111, thereby unlocking the down duct 120 and detaching the down duct 120 from the base 110.

[0043] Please refer to Figure 3 and Figure 4 , Figure 3 FIG. 1 is a cross-sectional view of a partial structure of the air conditioner 100. Figure 4 Another cross-sectional view of a portion of the structure of the air conditioner 100 is shown.

[0044] In this embodiment, the locking member 132 and the handle 131 are slidably engaged, and both are slidably engaged with the downwind duct 120. The handle 131 is configured to slide downward on the downwind duct 120 when pressed, thereby pushing the locking member 132 to slide in a first direction until it disengages from the locking portion 111. The first direction forms an angle with the sliding direction of the downwind duct 120.

[0045] In actual application, when the handle 131 is subjected to a downward pressing force, it slides downward on the downwind duct 120. During the sliding process, the locking member 132 is pushed to slide in the first direction on the downwind duct 120 until the locking member 132 slides to disengage from the locking portion 111. Figure 3 The direction indicated by the X arrow is the first direction. In fact, in this embodiment, the first direction is from front to back.

[0046] It should be noted that the downward pressing force and downward sliding of the handle 131 referred to in this embodiment can be in either a vertically downward or an obliquely downward direction. Furthermore, the orientation in this embodiment is defined based on the state in which the air conditioner 100 is mounted on a wall. The downward direction is a direction vertically or obliquely close to the ground, and the direction from front to back is a direction vertically or obliquely close to the wall.

[0047] In this embodiment, the handle 131 has a pushing bevel 1311, and the locking member 132 has a matching bevel 1321. The pushing bevel 1311 and the matching bevel 1321 are slidably fitted together, and both are inclined relative to the vertical direction and the first direction. The pushing bevel 1311 is used to push the locking member 132 to slide through the matching bevel 1321 when the handle 131 slides downward.

[0048] It can be understood that when the handle 131 is forced to slide downward, the inclined surface 1311 is pushed downward by the handle 131, thereby sliding relative to the mating inclined surface 1321, and applying a force in the first direction to the mating inclined surface 1321, thereby pushing the locking member 132 to slide in the first direction until it disengages from the locking portion 111, thereby releasing the lock on the downwind duct 120.

[0049] Regarding the sliding fit between the handle 131 and the downwind duct 120, in this embodiment, the downwind duct 120 has a guide slide 121 tilted in the vertical direction, and the handle 131 also has a guide slide slope 1315, which is slidably fitted with the guide slide 121. The guide slide 121 is used to guide the handle 131 to slide downward through the guide slide slope 1315 when the handle 131 is subjected to a downward pressing force.

[0050] In the first direction, the guide plate 121 and the matching bevel 1321 of the locking member 132 are arranged opposite each other, with the handle 131 positioned between the guide plate 121 and the matching bevel 1321. When the handle 131 is subjected to a downward pressure, the guide bevel 1315 slides relative to the guide plate 121, guiding the handle 131 to slide downward. During this process, the push bevel 1311 of the handle 131 pushes the locking member 132 to slide in the first direction.

[0051] In order to ensure a smooth relative sliding process between the handle 131 and the locking member 132, improve the compactness of the overall structure, and save available space in the lower air duct 120, in this embodiment, the locking member 132 has an assembly groove 1323, and the mating inclined surface 1321 is located on one side of the groove wall of the assembly groove 1323. The guide sliding plate 121 extends into the assembly groove 1323 and is arranged opposite to the mating inclined surface 1321 in the first direction. The handle 131 extends into the assembly groove 1323, and the guide sliding inclined surface 1315 and the pushing inclined surface 1311 are respectively located on the opposite sides of the handle 131 in the first direction.

[0052] In this embodiment, a movable channel is formed between the guide slide 121 and the mating inclined surface 1321, which gradually contracts from top to bottom. The structure of the handle 131 from the pushing inclined surface 1311 to the guide inclined surface 1315 is wedge-shaped, that is, the width in the first direction gradually increases from bottom to top. As the handle 131 slides downward along the guide slide 121, since the guide slide 121 is fixed in position, the mating inclined surface 1321 of the locking member 132 is continuously pushed in the first direction by the handle 131, causing the locking member 132 to slide in the first direction.

[0053] Regarding the sliding engagement between the locking member 132 and the downwind duct 120, in this embodiment, the downwind duct 120 has two mounting walls 122, each of which is provided with guide holes 1221 coaxially arranged in the first direction. The locking member 132 includes a main body 1324 and a slide rod 1325 connected to each other. The main body 1324 slides with the handle 131, and the ends of the slide rod 1325 are slidably mounted within the guide holes 1221 in the two mounting walls 122. The main body 1324 is located between the two mounting walls 122 and engages with the locking portion 111.

[0054] It is understood that the assembly groove 1323 is actually formed on the main body 1324, that is, the matching inclined surface 1321 is also provided on the main body 1324. When the handle 131 slides obliquely downward along the guide slide 121, a force in the first direction is directly applied to the main body 1324, thereby driving the slide bar 1325 to slide along the guide hole 1221 in the first direction until the main body 1324 is disengaged from the mounting portion on the downflow duct 120.

[0055] In this embodiment, the main body 1324 has a buckle 1326, and the locking portion 111 is provided with a hook 1111. The buckle 1326 engages with the hook 1111. Furthermore, to ensure a secure and reliable locking effect, in this embodiment, there are two buckles 1326 and two hooks 1111, each spaced apart in the first direction. The two buckles 1326 engage with the two hooks 1111, respectively. When the main body 1324 is pushed in the first direction by the handle 131, the two buckles 1326 and the two hooks 1111 are simultaneously disengaged, thereby unlocking the down duct 120.

[0056] In addition, the locking member 132 also includes an elastic reset member (not shown in the figure), which is sleeved on one end of the slide rod 1325, and the opposite ends of the elastic reset member are respectively abutted against the main body 1324 and a mounting wall 122, and is used to drive the main body 1324 to reset and slide in the second direction after the pressing force acting on the handle 131 is withdrawn, so as to push the handle 131 to reset and slide upward, and the second direction is opposite to the first direction.

[0057] The second direction is Figure 3 The direction indicated by the Y arrow in the figure is from back to front in this embodiment. In this embodiment, the elastic reset member is a spring, which is sleeved on one end of the slide bar 1325 in the first direction, and one end of the spring is abutted against the end of the main body 1324 in the first direction, and the other end is abutted against the corresponding mounting wall 122. In the process of the handle 131 pushing the main body 1324 to move in the first direction, the main body 1324 squeezes the spring to contract and accumulates elastic potential energy. When the pressing force applied to the handle 131 is removed, the spring releases the elastic potential energy and relaxes, pushing the main body 1324 to reset and slide. In this process, the matching inclined surface 1321 on the main body 1324 pushes the handle 131 to reset and slide upward through the pushing inclined surface 1311 on the handle 131.

[0058] It can be understood that in the actual process of assembling the down duct 120, the down duct 120 can be assembled to the base 110 while continuously applying a pressing force to the handle 131. After the assembly is in place, the pressing force is removed, and the elastic reset member can push the locking member 132 to cooperate with the locking portion 111 on the base 110, that is, the buckle 1326 is engaged with the hook 1111, thereby completing the locking of the down duct 120.

[0059] Alternatively, during the assembly of the down duct 120, no pressing force may be applied to the handle 131, and guiding slopes may be provided on the buckle 1326 and the hook 1111. During the assembly of the down duct 120, the guiding slopes on the hook 1111 and the guiding slopes on the buckle 1326 slide relative to each other, thereby pushing the buckle 1326 to move in the first direction until it passes over the hook 1111. During this process, the elastic reset member compresses and accumulates elastic potential energy. After the buckle 1326 passes over the hook 1111, the elastic reset member relaxes, pushing the main body 1324 to drive the buckle 1326 to complete the engagement with the hook 1111, thereby completing the locking of the down duct 120.

[0060] To limit the sliding stroke, in this embodiment, a limiting groove 1312 is recessed on the push inclined surface 1311. The limiting groove 1312 has upper and lower groove walls that are vertically opposed to each other. A limiting protrusion 1322 is convexly provided on the mating inclined surface 1321. The limiting protrusion 1322 extends into the limiting groove 1312, allowing movement between the upper and lower groove walls.

[0061] It is understood that when the buckle 1326 is engaged with the hook 1111, the handle 131 is in its initial state, i.e., in its upward limit position, while the locking member 132 is in its second-direction limit position. At this point, the lower wall of the limiting groove 1312 abuts against the limiting protrusion 1322 extending into the limiting groove 1312. As the handle 131 is pressed downward, the limiting protrusion 1322 gradually moves closer to the upper wall until it abuts against the upper wall, preventing further relative sliding between the handle 131 and the locking member 132. At this point, the handle 131 is in its downward limit position, while the locking member 132 is in its first-direction limit position.

[0062] Similarly, when the pressing force is released in the unlocked state, the elastic return member pushes the main body 1324 to slide in the second direction, and the limiting protrusion 1322 gradually moves closer to the lower groove wall until it abuts against the lower groove wall, preventing further relative sliding between the handle 131 and the locking member 132. At this point, the handle 131 is in the upper limit position, and the locking member 132 is in the second direction limit position.

[0063] In order to further reduce the difficulty of disassembling and assembling the downwind duct 120 and improve the installation performance, in this embodiment, the number of the locking parts 111 and the locking mechanisms 130 are both two, the two locking parts 111 are respectively located at the left and right ends of the base 110, and the two locking mechanisms 130 are respectively arranged at the left and right ends of the downwind duct 120, and the two locking parts 132 corresponding to the two locking mechanisms 130 cooperate with the two locking parts 111 respectively.

[0064] It is understood that when removing the down duct 120, the user operates from a low position, holding the left and right ends of the down duct 120 with both hands, and pressing the corresponding two handles 131 respectively. This can unlock the down duct 120 while providing stable support on the left and right sides of the down duct 120, and the down duct 120 can be easily removed from the base 110. Similarly, when assembling the down duct 120, the user operates from a low position, holding the left and right ends of the down duct 120 with both hands, and pushing the down duct 120 upward, the process is smooth, until the locking members 132 of the two locking mechanisms 130 engage with the two locking portions 111.

[0065] In summary, the air conditioner 100 provided in this embodiment can complete the disassembly and assembly of the downwind duct 120 conveniently and quickly, saving time and effort.

[0066] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
