Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a filter installation assembly and an air conditioner. Background Art

[0002] At present, air conditioners are equipped with filters to filter impurities in the air and prevent clogging of the evaporator. The filters generally need to be installed on the air conditioner housing by means of a snap assembly, but the snap assembly has a complex structure, is difficult to produce, and has high costs. Moreover, when the filters are installed on the air conditioner body by means of the snap assembly, multiple screws are still required for fixing, which affects production efficiency and increases production costs.

[0003] In order to filter impurities in the air, existing air conditioner indoor units usually install filters, but after a long time, the filters must be cleaned to avoid the problem of poor air intake. In existing air conditioners, after the filters are installed, the buckles are set on the inner side of the filters and the middle frame. The overall outer surface of the filters is smooth, and there is no point of force to apply when disassembling. Disassembly is relatively complicated, time-consuming and labor-intensive, and the filters are easily damaged. Summary of the invention

[0004] The invention solves the problem of how to prevent the filter screen from being damaged due to the difficulty in disassembling and assembling the filter screen.

[0005] To solve the above problems, the present invention provides a filter installation assembly, comprising: a filter, provided with at least one locking member installation area; the filter installation assembly also includes: at least one locking member, provided in the locking member installation area; each of the locking members includes: a locking portion and a disassembly portion; when the locking member rotates, the locking portion is locked or unlocked to disassemble and assemble the filter.

[0006] The filter installation assembly of the present invention realizes the assembly and disassembly of the filter by rotating the locking piece during the installation process; when the locking piece is rotated to the locking position, the locking part is locked; when the locking piece is rotated to the unlocking position, the locking part is unlocked; at the same time, the disassembly part is used to hold and apply external force to rotate the locking piece to realize the locking and unlocking process; on the other hand, the disassembly part is used to hold, which is convenient for disassembling the filter assembly in the unlocked state; the disassembly efficiency is greatly improved, the difficulty of disassembly is reduced, and damage to the filter is avoided, making the installation of the filter more convenient; at the same time, the installation of the filter is realized by arranging a locking piece on the filter, thereby reducing the space occupied by the filter during installation.

[0007] Furthermore, the locking member includes: a main body, having a lifting end and a locking end arranged opposite to each other; the lifting end is the disassembly part, and the locking end is the locking part; a rotating part, which is arranged on the main body; a rotating shaft is arranged in the locking member installation area, and the rotating part is rotatably connected to the rotating shaft, and when the locking member rotates, the locking end can switch between a locked state and an unlocked state.

[0008] By setting a lifting end to provide a force application position, the locking piece can be rotated under force; at the same time, it is also easy to hold, so that the filter assembly in the unlocked state can be removed and lifted; the locking end is used to cooperate and lock with the air conditioner middle frame during the installation of the filter assembly, so that the filter assembly can be installed on the middle frame; a rotating shaft is set to be rotatably connected with the rotating part, so that the lifting end and the locking end of the locking piece that are relatively arranged can rotate around the rotating shaft, so as to realize the conversion between the locked state and the unlocked state of the locking end; it is convenient to disassemble and install the filter.

[0009] Furthermore, the locking end extends downward and is bent or curved toward a side away from the rotating portion.

[0010] The locking end is arranged in a bent or curved shape, so that the locking end can be locked easily and the filter screen is not easy to slip off after installation.

[0011] Furthermore, the lifting end includes: a handle portion, which is arranged on both sides of the rotating portion opposite to the locking end; and a filter screen buckle end, which is arranged on the side of the main body.

[0012] A handle is provided to facilitate users to hold the filter when disassembling it, thereby improving disassembly efficiency. At the same time, the locking end is provided on both sides of the rotating part, thereby facilitating users to apply pulling force through the handle or downward pressure on the locking part to realize the rotation of the locking piece. A filter buckle connection end is provided on the side of the main body, and the filter buckle connection end is in a convex shape, and is locked by achieving an interference fit with the inner surface of the locking piece installation area.

[0013] Furthermore, the handle portion protrusion is arranged on the main body, and the handle portion and the rotating portion are located on opposite sides of the main body.

[0014] It is convenient for the user to use the protrusion to pry the body where the handle is located, so that the handle rotates around the rotating part to unlock the locking end, and then to disassemble the filter.

[0015] Furthermore, the handle portion and the rotating portion are located on the same side of the main body, and the handle portion is connected to the main body via a connecting piece.

[0016] The handle is connected to one side of the body through a connecting piece, which increases the connection strength of the handle; correspondingly, the lever arm of the handle is extended, making the rotation more labor-saving.

[0017] Furthermore, when the filter is in a locked state, the top surface of the main body is flush with the top surface of the locking member installation area, so as to hide the handle; when the filter is in an unlocked state, the handle rotates with the locking member, and the handle is away from the locking member installation area, so that it is convenient to hold the handle to remove the filter.

[0018] When the filter is in a locked state, that is, the state after the filter is installed, the main body is flush with the locking member installation area, which is convenient for hiding the handle and reducing the occupied space; compared with the installation of traditional filters, the structure of the installed filter is more compact and reasonable.

[0019] Furthermore, the filter screen also includes: a locking member buckling end, which is arranged at one side of the locking member installation area and is arranged in cooperation with the buckling end of the filter screen.

[0020] It can be understood that the locking member buckling end is matched with the filter buckling end, and when the filter is in a locked state, the locking member buckling end and the filter buckling end are buckled with each other; when the user applies a pulling force to the handle or applies downward pressure to the locking part, at least one of the locking member buckling end and the filter buckling end is deformed, so that the locking member buckling end and the filter buckling end are separated from each other, so that the filter is easy to disassemble when it is in an unlocked state. Of course, the filter buckling end can be a groove or a convex block, and the locking member buckling end can be a convex block or a groove matched with the filter buckling end.

[0021] Furthermore, the filter screen also includes: a limiting member, which is arranged at one side of the locking member installation area, and the limiting member is located above the rotating shaft; and is used to limit the rotation angle of the locking member.

[0022] The limiting member is used to limit the range of the rotation angle of the locking member, so that the end where the handle is located can be rotated to the optimal state, which is convenient for the user to disassemble the filter screen through the handle and improves the disassembly efficiency.

[0023] The present invention also provides an air conditioner, comprising: the filter installation assembly as described above; a middle frame, wherein the upper end surface of the middle frame is provided with a buckle portion; wherein when the filter installation assembly is installed on the middle frame, the buckle portion is locked with the locking portion.

[0024] The air conditioner of the present invention is provided with a buckle portion that cooperates with the lock portion provided on the filter installation assembly, making it easier to disassemble and assemble the filter installation assembly, greatly improving the filter disassembly and assembly efficiency. At the same time, the filter is installed by providing a locking piece on the filter, thereby reducing the space occupied by the filter during installation.

[0025] Furthermore, the buckling portion is a cross beam, and at least one cross beam is provided. When the filter installation assembly is assembled, the locking portion is locked with the cross beam.

[0026] At least one crossbeam and a locking portion are provided on the middle frame to achieve mutual locking, so the overall structure is simple and locking is convenient.

[0027] Furthermore, the middle frame includes: at least one middle frame buckling area arranged corresponding to the locking member installation area; the buckling part is a buckling shaft, and the buckling shaft is arranged in the middle frame buckling area. When the filter installation assembly is assembled, the buckling shaft and the locking part are locked.

[0028] A middle frame buckle connection area is provided, and a buckle connection shaft is provided in the middle frame buckle connection area, so that the buckle connection shaft and the locking part are locked more stably, avoiding the shaking generated during the use of the air conditioner, which causes the buckle connection shaft to separate from the locking part.

[0029] The present invention has the following beneficial effects:

[0030] 1) The filter is easy to disassemble and assemble, with high disassembly efficiency and low disassembly difficulty;

[0031] 2) When the filter is installed, it is firmly installed; it is not easy for the buckle shaft to separate from the locking end due to the shaking generated during the use of the air conditioner itself;

[0032] 3) The handle is easy to hide and takes up less space for installation; compared with the traditional filter installation, the structure is more compact and reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] 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.

[0050] Embodiment 1:

[0051] like Figure 1 As shown, this embodiment provides a filter installation assembly 1, including a filter 10 and a locking member 30; the locking member 30 includes: a locking portion and a disassembly portion; when the locking member 30 rotates, the locking portion is locked or unlocked to disassemble and assemble the filter 10.

[0052] Specifically, Figure 2As shown, at least one locking member installation area 102 is provided on the filter screen 10, and a rotating shaft 101 is provided in the locking member installation area 102; Figure 3 and Figure 4 As shown, the locking part is the locking end 303, and the disassembly part is the lifting end 304; the locking member 30 also includes: a body 301; the lifting end 304 and the locking end 303 are arranged at both ends of the body 301; a rotating part 302 is also arranged between the lifting end 304 and the locking end 303, and the rotating part 302 is arranged on the body 301; the rotating part 302 is provided with an axial hole 305, and the axial hole 305 is connected with the rotating shaft 101; so that the locking member 30 can rotate relative to the rotating shaft 101; by rotating the lifting end 304, The lifting end 304 rotates to the top of the rotating shaft 101, and correspondingly, the locking end 303 rotates to the bottom of the rotating shaft 101, thereby unlocking the filter 10, and lifting the filter 10 by the lifting end 304, thereby realizing the disassembly of the filter 10, which greatly reduces the difficulty of disassembly; similarly, when installation is required, the lifting end 304 is pressed to make the locking end 303 and the lifting end 304 rotate relative to the rotating shaft 101, so that the lifting end 304 and the locking end 303 are respectively locked, thereby realizing the installation of the filter 10.

[0053] For example, an opening is provided on one side of the shaft hole 305. When the locking member 30 and the rotating shaft 101 are assembled, at least one of them is deformed, so that the rotating shaft 101 is conveniently buckled into the shaft hole 305 from the opening. It can be understood that the width of the opening here is smaller than the diameter of the shaft hole, so that the rotating shaft 101 is not easy to slide out after being buckled in. At the same time, it is convenient for the disassembly and assembly of the locking member 30. Of course, the rotating part 302 can also be the rotating shaft 101, and the corresponding shaft hole 305 can be set in the locking member installation area 102, so as to achieve mutual cooperation.

[0054] Of course, the lifting end 304 and the rotating part 302 may also be located at both ends of the main body 301, and a locking end 303 is provided between the lifting end 304 and the rotating part 302. The locking end 303 is provided on the main body 301 to achieve rotation locking, which will not be described in detail here.

[0055] Embodiment 2:

[0056] like Figure 3 As shown, the locking end 303 extends downward and bends toward a side away from the rotating portion 302 .

[0057] Specifically, the locking end 303 includes a locking block 3031 and an extension block 3032. One end of the extension block 3032 is connected to the lower surface of the body 301, and the other end is connected to the locking block 3031. The connection between the locking block 3031 and the extension block 3032 forms a bend at a certain angle, and is bent toward the side away from the rotating part 302. The connection between the locking block 3031 and the extension block 3032 is set in a bent shape, which facilitates the locking block 3031 to achieve locking, so that the filter 10 is not easy to slip after installation.

[0058] like Figure 3 As shown, the lifting end 304 includes a handle portion 3041 and a filter screen buckling end 3042 .

[0059] Specifically, the handle 3041 and the locking end 303 are arranged on both sides of the rotating part 302; the handle 3041 is convexly arranged on the body 301, and the handle 3041 and the locking end 303 are arranged on both sides of the rotating part 302; the filter screen buckle end 3042 is arranged on the side of the body 301. It is convenient for the user to use the convexity to bend the body 301 where the handle 3041 is located, so that the handle 3041 rotates around the rotating part 302, and the locking end 303 is unlocked, and then the filter screen 10 is disassembled.

[0060] Embodiment 3:

[0061] like Figure 4 As shown, the locking end extends downward and bends toward a side away from the rotating portion 302 .

[0062] Specifically, the locking end includes a locking block 3031, one end of which is connected to the lower surface of the body 301, and the other end is curved in a groove shape toward the side away from the rotating part 302. The connection between the locking block 3031 and the extension block 3032 is curved to facilitate locking of the locking block 3031, so that the filter 10 is not easy to slip after installation.

[0063] like Figure 4 As shown, the handle 3041 and the rotating part 302 are located on the same side of the body 301, and are arranged on both sides of the rotating part 302 opposite to the locking block 3031. The handle 3041 is connected to the body 301 through the connecting piece 306; a first card slot (not shown in the figure) is provided at the connection between the handle 3041 and the connecting piece 306, and the filter screen buckle end 3042 is arranged on the side of the body 301. It can be understood that the handle 3041 is provided to facilitate the user to hold when disassembling the filter screen 10, thereby improving the disassembly efficiency; at the same time, it is arranged on both sides of the rotating part 302 opposite to the locking block 3031, so that the user can apply a pulling force through the handle 3041 or apply downward pressure to the locking block 3031 to realize the rotation of the locking piece 30.

[0064] Preferably, the distance between the handle portion 3041 and the rotating portion 302 is greater than the distance between the rotating portion 302 and the locking block 3031. This makes it easier for the user to open the locking member 30 through the handle portion 3041.

[0065] The structure of the handle portion 3041 and the locking end in this embodiment can also be used in combination with the structure of the handle portion 3041 and the locking end 303 in Example 3.

[0066] Embodiment 4:

[0067] like Figure 3 and Figure 4 As shown, the contact surface of the handle portion 3041 is also provided with anti-skid grooves to facilitate the user to rotate the locking member 30 and prevent slipping; the contact surface here refers to the surface that applies force to the handle portion 3041 when the user rotates the locking member 30.

[0068] Further, such as Figure 5 As shown, the filter 10 further includes: a stopper 103, which is disposed on one side of the locking member installation area 102 and is located above the rotating shaft 101; and is used to limit the rotation angle of the locking member 30. The stopper 103 is used to limit the range of the rotation angle of the locking member 30, so that the end where the handle 3041 is located can be rotated to the best state, which is convenient for the user to disassemble the filter 10 through the handle 3041, thereby improving the disassembly efficiency.

[0069] For example, the stopper 103 is a protrusion disposed in the locking member installation area 102, and the protrusion length of the protrusion is greater than the gap between the locking member 30 and the locking member installation area 102; thereby limiting the rotation angle of the locking member 30, see Fig.14 When the filter screen 30 is disassembled, the locking member 30 is rotated by the handle portion 3041 so that the limiting member 103 presses against the surface of the body 301 away from the rotating shaft 101, thereby achieving a limiting effect.

[0070] Preferably, the limit member 103 is located directly above the rotating shaft 101; at this time, under the premise of not affecting the rotation of the locking member 30, the limiting effect of the limit member 103 is optimal, and at the same time, the end where the handle 3041 is located is rotated to the optimal state, so that the user can hold the handle 3041 to the maximum extent to disassemble the filter 10.

[0071] Further, such as Figure 5 As shown, a second slot 104 is also provided on one side of the locking member installation area 102, and the second slot 104 is provided in cooperation with the connecting member 306. Fig.13 As shown, the connecting member 306 is buckled into the second slot 104 , so that the locking member 30 as a whole is more closely fitted to the filter screen 10 .

[0072] Embodiment 5:

[0073] like Figure 6 As shown, this embodiment further provides an air conditioner 100 , comprising the filter installation assembly 1 and the middle frame 20 in the above embodiment, and the filter installation assembly 1 is detachably installed on the middle frame 20 .

[0074] Specifically, Figure 7 As shown, the upper end surface of the middle frame 20 is provided with an air inlet 202 and a buckle portion, and the buckle portion is at least one crossbeam 201, and the crossbeam 201 divides the air inlet 202, and divides the air inlet 202 into multiple air inlet areas; Figure 8 , Fig. 9 as well as Fig.10 As shown, when the filter installation assembly 1 is assembled, the locking block 3031 locks the side of the cross beam 201 close to the air inlet 202; the filter buckle end 3042 and the locking member buckle end 3043 are buckled with each other, so that the filter installation assembly 1 is installed at the air inlet 202 of the middle frame 20. By providing at least one cross beam 201 on the middle frame 20 and the locking end 303 to achieve mutual locking, the overall structure is simple and locking is convenient.

[0075] For example, the crossbeam 201 here can also be arranged according to the position set by the locking end 303; for example, the crossbeam 201 here is changed from being placed vertically to being placed horizontally, and the locking end 303 is arranged on the body 301 close to one side of the crossbeam 201.

[0076] Further, such as Fig. 9 As shown, when the filter screen 10 is in the locked state, the top surface of the body 301 is flush with the top surface of the locking member installation area 102, which is used to hide the locking member 30; thus saving the overall installation space; Fig.10 As shown, when the filter 10 is in the unlocked state, the handle 3041 rotates with the locking member 30 , and the handle 3041 is away from the locking member installation area 102 , so that the filter 10 can be removed by holding the handle 3041 .

[0077] Further, such as Fig.11 As shown, at least one middle frame buckle area 204 is arranged corresponding to the locking member installation area 102, the buckle part is a buckle shaft 203, the buckle shaft 203 is arranged in the middle frame buckle area 204, and the buckle shaft 203 is arranged in cooperation with the locking block 3031. Specifically, as Fig.12 and Fig.13As shown, during the assembly process, the groove-shaped curved portion of the locking block 3031 is first hooked on the surface of the buckling shaft 203, and then the filter buckling end 3042 and the locking member buckling end 3043 are buckled with each other; the handle 3041 is buckled on the middle frame 20 through a first slot (not shown in the figure); so that the filter installation assembly 1 is installed at the air inlet 202 of the middle frame 20. By setting the middle frame buckling area 204, the middle frame buckling area 204 is provided with a buckling shaft 203, and the buckling shaft 203 and the locking end 303 are locked more stably, avoiding the shaking generated during the use of the air conditioner, which causes the buckling shaft 203 and the locking end 303 to separate.

[0078] For example, the filter screen buckling end 3042 may be a groove or a protrusion, and the locking member buckling end 3043 may be a protrusion or a groove that is configured to cooperate with the filter screen buckling end 3042 .

[0079] Alternatively, the filter screen buckle connection end 3042 may be a protrusion, the inner surface of the locking member installation area 102 is a plane, and the filter screen buckle connection end 3042 and the inner surface of the locking member installation area 102 are interference fit.

[0080] Specifically, when installing the filter assembly 1, pressure is applied downward to the handle 3041 to buckle and press, so that at least one of the filter buckle end 3042 and the inner surface of the locking piece installation area 102 is deformed, so that the filter buckle end 3042 and the inner surface of the locking piece installation area 102 are interference fit, and the locking block 3031 and the buckle part are buckled and locked; the filter 10 is locked and installed. Similarly, when disassembling the filter assembly 1, pulling force is applied to the handle 3041 to lift it up, so that at least one of the filter buckle end 3042 and the inner surface of the locking piece installation area 102 is deformed, so that the filter buckle end 3042 and the inner surface of the locking piece installation area 102 are separated, and the locking block 3031 and the buckle part are unlocked, and the filter 10 is disassembled.

[0081] Although the present invention is disclosed as above, the present invention 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 invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
