DETAILED DESCRIPTION
[0036] As disclosed in the background technology, the prior art is aimed at air conditioners that are easy to disassemble and assemble. In order to achieve quick disassembly between the crossflow fan blades and the motor, an opening is usually set at the end of the middle frame to facilitate the disassembly and assembly of the fan blades and the motor. At the opening, a locking member is usually required to limit the position of the movable parts. The existing locking member is usually fixed to the middle frame by screws, so it is only necessary to open a screw hole on the middle frame and a through hole on the locking member. The screw passes through the through hole and is assembled on the screw hole to achieve the fixation of the locking member. During disassembly, after the screw is removed from the screw hole, since the hole on the locking member is a through hole, the screw cannot be limited and fixed. The screw needs to be removed and stored separately. The disassembly usually requires a ladder operation, which undoubtedly increases the cumbersomeness of the maintenance work.
[0037] In order to solve the above problems, the present invention provides a new type of air conditioner. In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0038] First embodiment
[0039] See also Figures 1 to 3 The present embodiment provides an air conditioner 100, which is suitable for an air conditioner that is easy to disassemble and wash. When disassembling the air conditioner 100, there is no need to remove the screws separately for separate storage, thereby avoiding the loss of the screws and improving the convenience of maintenance operations.
[0040] The air conditioner 100 provided in this embodiment includes a middle frame 110, a locking plate 130 and a fixing member 150, one end of the locking plate 130 is hinged to the rear of the middle frame 110, and the other end of the locking plate 130 is connected to the front of the middle frame 110 for locking movable parts on the middle frame 110, wherein a first screw hole 170 is provided at one end of the locking plate 130 connected to the front of the middle frame 110, and the fixing member 150 is threadedly assembled in the first screw hole 170, and a second screw hole 190 is also provided at the front of the middle frame 110, and the fixing member 150 passes through the first screw hole 170 and is correspondingly threadedly assembled in the second screw hole 190.
[0041] In this embodiment, the air conditioner further includes a crossflow fan blade and a motor, both of which are arranged in the middle frame 110, and the crossflow fan blade and the motor are a detachable transmission connection structure, wherein the movable parts on the middle frame 110 in this embodiment can be an end cover structure connected to the crossflow fan blade or other parts that need to be disassembled. In addition, the end surface of the middle frame 110 is also provided with an opening to facilitate the axial movement of the crossflow fan blade to achieve assembly and disassembly with the motor. The lock plate 130 is arranged at the end of the middle frame 110, which can realize the locking effect of the opening, thereby realizing the position limitation of the crossflow fan blade.
[0042] It is worth noting that in this embodiment, one end of the lock plate 130 is hinged to the rear of the middle frame 110, and the other end of the lock plate 130 is joined to the front of the middle frame 110, so that the movable parts connected to the cross-flow fan blades on the middle frame 110 can be locked to limit the position of the cross-flow fan blades, and a first screw hole 170 is provided at one end of the lock plate 130 close to the front of the middle frame 110, and a fixing member 150 is threadedly assembled in the first screw hole 170. A second screw hole 190 is also provided at the front of the middle frame 110. After the fixing member 150 passes through the first screw hole 170, it is correspondingly threadedly assembled in the second screw hole 190 to fix the lock plate 130. When disassembling, the fixing piece 150 can be screwed outward until the fixing piece 150 is disengaged from the second screw hole 190, thereby facilitating the locking plate 130 to be disengaged from the front of the middle frame 110 and rotated to unlock, thereby releasing the position limit of the movable part on the middle frame 110. At this time, the fixing piece 150 is not removed from the first screw hole 170, but is always assembled in the first screw hole 170. The internal thread of the first screw hole 170 can limit the position of the fixing piece 150, avoiding the need to remove the fixing piece 150 separately for storage, thereby improving the convenience of maintenance operations.
[0043] It should be noted that in this embodiment, locking plates 130 can be set at both ends of the middle frame 110 to achieve locking and limiting of different movable parts on the middle frame 110. In this embodiment, the locking plate 130 at one end is used as an example for description.
[0044] See also Figures 4 to 8, further, the locking plate 130 includes an integrally arranged first section 131 and a second section 133, one end of the first section 131 is hinged on the middle frame 110 and is used to lock the movable parts on the middle frame 110, the second section 133 is connected to the other end of the first section 131, and is bent relative to the first section 131 and extends to the front side of the middle frame 110, and the first screw hole 170 is opened at the end of the second section 133 away from the first section 131. Specifically, the first section 131 and the second section 133 form an L-shaped bending structure, that is, the first section 131 and the second section 133 can be perpendicular to each other, and a transition bending structure is used at the bending. In this embodiment, the first section 131 and the second section 133 are bent, and the first section 131 is used to realize the function of locking the movable parts, and the second section 133 is used to realize the position fixing, and the bending setting can make the second section 133 bend forward to the front side of the middle frame 110, which is convenient for directly screwing the fixing member 150 from the front side during assembly or disassembly, which is very convenient. Furthermore, the use of a bent locking plate 130 can also increase the locking range and ensure the locking limit effect.
[0045] It should be noted that, in this embodiment, the rear portion of the middle frame 110 refers to the portion close to the wall after installation, and the front portion of the middle frame 110 refers to the portion close to the air outlet. In addition, the inner side of the middle frame 110 refers to the side close to the center of the crossflow fan blade, and the outer side of the middle frame 110 refers to the side close to the user.
[0046] In other preferred embodiments of the utility model, a connecting rod can be provided on the inner side of the first section 131, and the connecting rod can be connected to the movable part on the middle frame 110, so that during the process of unlocking and opening the first section 131, the movable part can be driven to move, so that when the lock plate 130 is opened, the movable part connected to the cross-flow fan blade can be pulled outward at the same time, so as to adjust the position of the cross-flow fan blade and make the cross-flow fan blade disengage from the motor, which is convenient for subsequent direct disassembly.
[0047] In this embodiment, a hinge sleeve 135 is further provided at one end of the first section 131 away from the second section 133, and a hinge shaft 111 is provided at the rear of the middle frame 110. The hinge sleeve 135 extends into the rear of the middle frame 110 and is movably sleeved on the hinge shaft 111 to drive the first section 131 and the second section 133 to rotate relative to the middle frame 110. Specifically, the size of the opening on the hinge sleeve 135 is adapted to the size of the hinge shaft 111, so that the hinge sleeve 135 can rotate freely relative to the hinge shaft 111. By using the matching arrangement of the hinge shaft 111 and the hinge sleeve 135, the hinge of the lock plate 130 can be realized, and the lock plate 130 can rotate relative to the middle frame 110 under the action of an external force, so as to realize the unlocking and locking actions on the one hand, and on the other hand, by separately arranging the hinge sleeve 135, the structural strength of the hinge position on the lock plate 130 can be improved, and it is avoided to directly open a hole on the first section 131, thereby improving the overall structural strength of the lock plate 130.
[0048] In this embodiment, the articulated sleeve 135 protrudes inward relative to the first section 131, and the first section 131 is located outside the end surface of the middle frame 110. Specifically, the articulated sleeve 135 is integrally provided at one end of the first section 131 and protrudes inward, so that the opening position on the articulated sleeve 135 is separated from the first section 131 by a distance. The articulated sleeve 135 protrudes inward, so that the articulated sleeve 135 can be extended into the middle frame 110 while the first section 131 is located outside the middle frame 110, thereby ensuring the parallel locking effect of the first section 131 and avoiding interference between the first section 131 and the middle frame 110.
[0049] In this embodiment, the end surface of the middle frame 110 is further provided with a receiving groove 113, and the first section 131 is received in the receiving groove 113. Specifically, the width of the receiving groove 113 is adapted to the width of the first section 131, so as to ensure that the first section 131 can be received in the receiving groove 113. By providing the receiving groove 113, on the one hand, the integrity of the outer end surface of the middle frame 110 can be ensured to avoid local protrusions, and on the other hand, the first section 131 can be further prevented from interfering with the middle frame 110 during movement.
[0050] In this embodiment, the bottom edge of the first section 131 and / or the second section 133 is provided with a reinforcing fold 115. Preferably, since the first section 131 mainly plays a locking role and has force transmission with the movable parts, the reinforcing fold 115 can be provided on the bottom edge of the first section 131, and the bottom edge of the second section 133 can be provided with a reinforcing fold 115 or not. By adding the reinforcing fold 115, the structural strength of the lock plate 130 can be improved, and the lock plate 130 and other components can be connected stably. At the same time, the reinforcing fold 115 is located at the bottom edge, so that a gap opening can be left at the top edge, which is convenient for manually pulling out the lock plate 130.
[0051] In this embodiment, a mounting post 117 is further provided on the second section 133, and a through hole 119 is provided on the mounting post 117, and the through hole 119 corresponds to the first screw hole 170. The fixing member 150 is penetrated through the through hole 119, and the mounting post 117 is held against the front side of the middle frame 110, so that the through hole 119 corresponds to the second screw hole 190. Specifically, a mounting post 117 is further provided on the inner side of one end of the second section 133 away from the first section 131, and the mounting post 117 is provided with a through hole 119, and the through hole 119 corresponds to the first screw hole 170. The fixing member 150 passes through the first screw hole 170 and the through hole 119 in sequence and is assembled to the second screw hole 190. The provision of the mounting post 117 can improve the structural strength of the second section 133 on the one hand, and can further limit and fix the fixing member 150 on the other hand, so as to ensure the strength of the connection structure between the fixing member 150 and the second section 133.
[0052] It should be noted that the mounting post 117 is integrally arranged on the second section 133 , and in the locked state, the through hole 119 , the first screw hole 170 and the second screw hole 190 are concentrically arranged, which can ensure the concentric installation of the fixing member 150 .
[0053] In this embodiment, the first screw hole 170 extends to a portion of the mounting column 117, and the aperture of the through hole 119 is larger than the aperture of the first screw hole 170. Specifically, the internal thread in the first screw hole 170 can extend to a portion of the mounting column 117, which can increase the axial length of the first screw hole 170, thereby better limiting the fixing member 150, and the larger aperture of the through hole 119 can avoid interference with the fixing member 150, ensuring that the fixing member 150 can smoothly pass through the through hole 119 and enter the second screw hole 190.
[0054] It should also be noted that the setting of the mounting column 117 here can also create a gap between the second section 133 and the front surface of the middle frame 110. The gap can form a shielding space, which is convenient for shielding the buttons on the front surface of the middle frame 110 and other parts that need to be hidden.
[0055] Further, the fixing member 150 is a screw, and the fixing member 150 includes a fixing cap 151 and a screw 153 which are integrally arranged, the diameter of the fixing cap 151 is larger than the aperture of the first screw hole 170, the screw 153 is sequentially inserted into the first screw hole 170, the guide hole 119 and the second screw hole 190, and is threadedly matched with the first screw hole 170 and the second screw hole 190, and the length of the screw 153 along the axial direction is 2-5 times the length of the mounting column 117 along the same direction. Preferably, the length of the screw 153 is 3 times the length of the mounting column 117. By setting the length of the screw 153 to 2-5 times the length of the mounting column 117, it is possible to ensure that the screw 153 is long enough and smoothly penetrates into the second screw hole 190 to a sufficient depth, thereby ensuring the fixing effect, and at the same time, when the screw 153 is removed from the second screw hole 190, the screw 153 also has enough length to remain in the first screw hole 170, thereby preventing the fixing member 150 from falling off directly from the first screw hole 170.
[0056] In summary, the present embodiment provides an air conditioner 100, in which one end of the locking plate 130 is hinged at the rear of the middle frame 110, and the other end of the locking plate 130 is joined to the front of the middle frame 110, so that the movable parts connected to the cross-flow blades on the middle frame 110 can be locked to limit the position of the cross-flow blades, and a first screw hole 170 is provided at one end of the locking plate 130 close to the front of the middle frame 110, and a fixing member 150 is threadedly assembled in the first screw hole 170, and a second screw hole 190 is also provided at the front of the middle frame 110, and the fixing member 150 passes through the first screw hole 170 and is correspondingly threadedly assembled in the second screw hole 190 to fix the locking plate 130. When disassembling, the fixing member 150 can be screwed outward until the fixing member 150 is disengaged from the second screw hole 190, so that the lock plate 130 can be disengaged from the front of the middle frame 110 and rotated to unlock, and the position limit of the movable part on the middle frame 110 is released. At this time, the fixing member 150 is not removed from the first screw hole 170, but is always assembled in the first screw hole 170. The internal thread of the first screw hole 170 can limit the position of the fixing member 150, avoiding the need to remove the fixing member 150 separately for storage. Compared with the prior art, the air conditioner 100 provided in this embodiment does not need to remove the fixing member 150 separately for separate storage when disassembling, avoiding the loss of the fixing member 150 and improving the convenience of maintenance operations.
