Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner end cover, a middle frame assembly and an air conditioner. Background Art

[0002] As people's demands for quality of life become higher and higher, higher requirements are also placed on the cleaning and maintenance of air conditioners. Correspondingly, the components of the air duct system of the air conditioner have become the key areas for cleaning and maintenance. For the current split wall-mounted air conditioners, opening the front panel operation is often restricted by the middle frame skeleton, making it difficult to remove the corresponding components. At this time, if you start from the end cover, you can avoid the obstruction of the middle frame skeleton and move the least parts to remove the parts that need maintenance or replacement.

[0003] However, currently when the end cover is opened, its open position cannot be located, and it is easy to return to the closed state under its own gravity or external force, which affects the disassembly of parts. Summary of the invention

[0004] The purpose of the present invention is to reduce the difficulty of disassembling parts by positioning the opening position of the end cover.

[0005] To achieve the above-mentioned purpose, the present invention provides an air conditioner end cover, which is arranged on the end opening of the air conditioner, and the air conditioner end cover includes: an upper end cover and a lower end cover; the lower end cover is rotatably connected to the upper end cover to close or open the end opening; and also includes a locking mechanism, when the lower end cover is opened, the locking mechanism is used to position the open position of the lower end cover.

[0006] The present invention is provided with a locking mechanism. When the lower end cover is rotated open relative to the upper end cover until the locking mechanism is locked, the end cover opening is exposed to the outside. At this time, the locking mechanism locks the open position of the lower end cover to prevent the lower end cover from rotating in the opposite direction under its own gravity or external force to automatically cover the end opening. In the process of opening the lower end cover and disassembling parts, interference with the disassembly process is avoided, thereby reducing the difficulty of disassembling parts and improving user experience.

[0007] Furthermore, the lower end cover is rotatably connected to the upper end cover via a connecting plate; one end of the connecting plate is rotatably connected to the upper end cover; and the other end of the connecting plate is fixedly connected to the lower end cover.

[0008] The lower end cover is movably connected to the upper end cover by a connecting plate, which facilitates the lower end cover to rotate and open relative to the upper end cover, and limits the rotation and opening trajectory of the lower end cover relative to the upper end cover, so that it can be opened or closed along a predetermined trajectory. At the same time, when the lower end cover is closed, the lower end cover can cooperate with the position of other components along the predetermined trajectory to prevent installation misalignment and improve installation efficiency.

[0009] Furthermore, the locking mechanism includes: at least one locking hole, which is arranged on the connecting plate; at least one buckle, which is arranged on the upper end cover, and each of the buckles is arranged corresponding to each of the locking holes.

[0010] By providing a buckle and a lock hole that cooperates with the buckle, when the lower end cover is rotated to open, the lock hole provided on the connecting plate is buckled with the buckle provided on the upper end cover to lock the open position of the lower end cover.

[0011] The present invention also provides a middle frame assembly, comprising the air conditioner end cover as described in any one of the above items.

[0012] The present invention also provides an air conditioner, comprising: a middle frame body, provided with an end opening; a base connected to the middle frame body; the air conditioner end cover as described above, covering the end opening; and a locking mechanism, provided between the lower end cover and the base.

[0013] By arranging the locking mechanism between the lower end cover and the base, when the lower end cover is rotated and opened relative to the base, the locking mechanism can support the open position of the lower end cover and prevent the lower end cover from rotating in the opposite direction under its own gravity or external force. In this way, when the lower end cover is opened and the parts are disassembled, interference with the disassembly process is avoided, thereby reducing the difficulty of disassembling the parts and improving the user experience.

[0014] Furthermore, the locking mechanism includes: a hinged rod group, hinged between the lower end cover and the base; a locking portion, arranged on the hinged rod group; wherein, when the lower end cover is rotated open relative to the upper end cover, the locking portion locks the hinged rod group into an extended state.

[0015] It can be understood that the hinged rod group can be composed of multiple hinged rods that are hinged to each other, and the hinged rods can move relative to each other as the lower end cover rotates; when the lower end cover is rotated open relative to the upper end cover until the locking mechanism is locked, the locking portion locks the hinged rod group into an extended state, providing sufficient supporting force to lock the lower end cover in the open position, thereby increasing the stability of the lower end cover when it is opened and locked.

[0016] Furthermore, the hinged rod member group includes: a first rod member, one end of which is hingedly connected to the lower end cover; and a second rod member, which is hingedly connected between the first rod member and the base.

[0017] It can be understood that the hinged rod group formed by connecting the first rod and the second rod has a simple structure, reduces the space occupied by parts, and can achieve the purpose of the lower end cover rotating and opening relative to the upper end cover through the rotation between the first rod and the second rod.

[0018] Furthermore, the locking portion also includes: a protrusion, which is arranged on the second rod; and a slot, which is arranged at the other end of the first rod; wherein the slot and the protrusion are arranged; when the lower end cover is opened, the slot and the protrusion are engaged to position the lower end cover at the open position.

[0019] It can be understood that a convex buckle is provided on the second rod member, and a groove matching the convex buckle is provided on the first rod member. When the lower end cover is rotated and opened relative to the upper end cover, the first rod member is rotated to be in a straight line with the second rod member. At this time, the convex buckle and the groove are buckled and locked, so that the first rod member is not easy to rotate relative to the second rod member under the influence of its own weight or external force, which is convenient for the disassembly and assembly of parts. At the same time, when the lower end cover is opened, the first rod member and the second rod member are rotated to a straight line to be locked, and the upper end cover, the lower end cover, and the first rod member and the second rod member form a triangle, which greatly improves the stability of the lower end cover in the locked state.

[0020] Furthermore, the air conditioner also includes: a water outlet, which is arranged on the base; a drainage pipe joint, which is arranged in cooperation with the water outlet; and a first connecting rod, which is rotatably connected between the lower end cover and the drainage pipe joint.

[0021] By arranging the first connecting rod to be rotatably connected between the lower end cover and the drain pipe joint, the drain pipe joint can be pulled out conveniently as the lower end cover rotates without manual pulling, thereby greatly simplifying the disassembly process of the drain pipe joint; the drain pipe joint can be quickly disassembled, and the position of the drain pipe joint after disassembly can be fixed to prevent the drain pipe joint from falling, thereby improving user experience.

[0022] Furthermore, the air conditioner also includes: a sliding mechanism, one end of which is connected to the base, and the other end of which is connected to the drain pipe joint.

[0023] It can be understood that when the drain pipe joint is opened and closed along with the lower end cover, the connection end of the drain pipe joint and the sliding mechanism can slide back and forth in the sliding mechanism, thereby providing a guide for the disassembly of the drain pipe.

[0024] Furthermore, the sliding mechanism includes: a slide rail, which is arranged on the side of the base close to the air conditioner end cover; a second connecting rod, one end of which is slidably connected to the slide rail and the other end is connected to the drainage pipe joint.

[0025] The drain pipe joint can drive the second connecting rod to move, thereby driving one end of the second connecting rod to slide in the slide rail. The slide rail can limit the sliding direction of one end of the second connecting rod to limit the position and sliding direction of the drain pipe joint, thereby facilitating the removal of the drain pipe joint from the water outlet.

[0026] Furthermore, the second connecting rod includes: a sliding portion, which is arranged in the slide rail; and a connecting portion, one end of which is connected to the sliding portion and the other end of which is fixedly connected to the drainage pipe joint.

[0027] It can be understood that the drainage pipe joint can drive the sliding part to slide in the sliding rail through the connecting part, and the sliding rail can limit the sliding direction of the sliding part.

[0028] Furthermore, the second connecting rod also includes: a mounting portion, which is in a ring shape and is sleeved on the surface of the drainage pipe joint; a flange is provided at one end of the drainage pipe joint close to the water outlet, and the mounting portion is in contact with the flange.

[0029] It can be understood that the flange can stop the mounting portion to prevent the mounting portion from being separated from the drain pipe joint.

[0030] Furthermore, the sliding part includes: a first column, fixedly connected to the connecting part; a connecting platform, one end of which is fixedly connected to the first column; and a second column, fixedly connected to the other end of the connecting platform; wherein both the first column and the second column are slidably matched with the slide rail, and the connecting part extends out of the slide rail.

[0031] It can be understood that the slide rail can limit the first column and the second column at the same time to prevent the sliding part from rotating relative to the slide rail, thereby ensuring the stability of the sliding cooperation between the sliding part and the slide rail.

[0032] The beneficial effects of the present invention are as follows: it can lock the open position of the lower end cover to prevent the lower end cover from automatically closing under its own gravity or external force, thereby reducing the difficulty of disassembling parts and components and improving user experience; it simplifies the disassembly process of the drain pipe joint; it can realize the rapid disassembly of the drain pipe joint, and it can fix the position of the drain pipe joint after disassembly to prevent the drain pipe joint from falling, thereby improving user experience.
