Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner indoor unit. Background Art

[0002] During long-term use, the air duct, wind wheel, water channel and other parts of the air conditioner indoor unit are easily dirty due to dust accumulation, so the air conditioner needs to be disassembled and cleaned regularly. In the prior art, the base of the indoor unit is composed of a detachably connected upper base and a lower base. When disassembling and assembling the fan assembly of the air conditioner indoor unit, the lower base needs to be disassembled as a whole, which causes unnecessary troubles due to the numerous disassembly and assembly steps. Summary of the invention

[0003] The present invention aims to solve to a certain extent the technical problem in the prior art that when disassembling the fan assembly, the lower base assembly needs to be disassembled as a whole.

[0004] To solve the above problems, the present invention provides an air-conditioning indoor unit, comprising an upper base assembly, a fan assembly and a lower base assembly, wherein the fan assembly is mounted on the lower base assembly, the upper base assembly is detachably connected to the lower base assembly, and the lower base assembly is rotatably connected to the upper base assembly, and the lower base assembly has a first position for facilitating the operation of the fan assembly and a second position for facilitating the removal of the fan assembly.

[0005] Therefore, by installing the fan assembly on the lower base assembly, the lower base assembly is rotatably connected to the upper base assembly. When the fan assembly needs to be disassembled and cleaned, the lower base assembly can be rotated downward to make room for disassembly of the fan assembly, thereby avoiding the overall disassembly of the lower base assembly and the upper base assembly, simplifying the disassembly and assembly steps of the fan assembly, and realizing rapid disassembly and assembly of the fan assembly.

[0006] Optionally, the lower base assembly includes a lower base and a lower cover, the fan assembly is mounted on the lower base, the lower base and the lower cover are detachably connected, and the lower cover is rotatably connected to the upper base assembly.

[0007] Thus, by installing the fan assembly on the lower base, the lower cover is rotatably connected to the upper base assembly; when the fan assembly needs to be disassembled, the lower base rotates along with the lower cover, avoiding the disassembly of the lower cover, further simplifying the disassembly and assembly of the fan assembly. Furthermore, through the detachable connection between the lower cover and the lower base, when the lower base needs to be disassembled and cleaned, the lower base can be disassembled and assembled separately, thereby reducing the disassembly and assembly steps of the lower base.

[0008] Optionally, the lower base includes a clamping ring, the lower cover includes a clamping column, and the clamping ring and the clamping column are clamped and connected.

[0009] Therefore, through the clamping cooperation between the clamping column and the clamping ring, when the lower base needs to be disassembled, the lower base can be directly pulled out along the clamping direction, which reduces the disassembly and assembly steps of the lower base and facilitates the disassembly and assembly of the lower base.

[0010] Optionally, the upper base assembly includes a first connecting arm, the lower cover includes a second connecting arm, the first connecting arm is provided with a rotating shaft, the second connecting arm is provided with a rotating shaft connecting hole, and the rotating shaft is rotatably connected to the rotating shaft connecting hole.

[0011] Thus, the first connecting arm and the second connecting arm are connected by rotation through the rotating shaft and the rotating shaft connecting hole. By setting the first connecting arm and the second connecting arm, an escape space is formed between the lower cover and the upper base assembly to prevent the upper base assembly from interfering with the rotation of the lower base when the lower base rotates following the lower cover.

[0012] Optionally, a tube-passing hole is provided on the rotating shaft, and the tube-passing hole is coaxial with the rotating shaft connecting hole.

[0013] Thus, the advantage of such a configuration is that, by providing a pipe hole on the rotating shaft, the drain pipe can pass through the pipe hole to directly communicate with the interior of the air conditioner indoor unit, avoiding the need to disassemble the housing of the indoor unit when installing the drain pipe, thereby simplifying the installation of the drain pipe. By setting the pipe hole and the rotating shaft connecting hole coaxially, the drain pipe and the rotating shaft are coaxial, thereby avoiding the drain pipe interfering with the rotation of the second connecting arm.

[0014] Optionally, a water receiving trough is provided on the lower base, a drainage nozzle is provided on the water receiving trough, a water channel is provided on the second connecting arm, one end of the water channel is connected to the drainage nozzle, and the other end of the water channel is used to connect with the environment.

[0015] Thus, by providing a water channel on the second connecting arm, the liquid in the water receiving trough flows into the drain pipe through the water channel and then is discharged through the drain pipe, thereby achieving the discharge of the liquid in the water receiving trough. The provision of the water channel avoids direct connection between the drain pipe and the drain nozzle, thereby facilitating the disassembly and replacement of the drain pipe.

[0016] Optionally, a drain pipe is also included, which passes through the pipe hole and is connected with the other end of the water channel. The drain pipe is made of a hose.

[0017] Therefore, when the lower cover rotates downward, the drain pipe made of a hose can reduce the obstruction of the drain pipe to the rotation of the lower base assembly.

[0018] Optionally, the second connecting arm is detachably connected to the lower cover.

[0019] Therefore, by detachably connecting the second connecting arm to the lower cover, when the lower base needs to be disassembled, the second connecting arm can be disassembled first to avoid the water channel hindering the disassembly of the lower base.

[0020] Optionally, the direction in which the lower base and the lower cover are detachably connected is the same as the axis of the drain nozzle.

[0021] Therefore, by limiting the direction of the detachable connection between the lower base and the lower cover, when the lower base is removed, the drain nozzle and the water channel are coaxial, thereby preventing the water channel from interfering with the removal of the lower base.

[0022] Optionally, the air conditioner indoor unit further includes a wind sweeping blade assembly, and the wind sweeping blade assembly is mounted on the lower cover.

[0023] Therefore, through the arrangement of the wind sweeping blade assembly, when the air conditioner indoor unit is running, the wind sweeping blade assembly swings left and right to realize automatic adjustment of the air outlet direction of the air conditioner indoor unit.

[0024] Optionally, the air conditioner indoor unit further comprises an upper shell, the upper shell is connected to the upper base assembly, and the upper shell is suitable for being enclosed with the lower cover to form a space for accommodating the upper base assembly and the lower base.

[0025] Thus, by disposing the upper shell, the upper shell and the lower cover are combined to form the outer shell of the indoor unit, and the upper base assembly and the lower base are accommodated in the outer shell, thereby shielding the upper base assembly and the lower base.

[0026] Optionally, a latch hole is provided on the upper base assembly, and the lower base assembly includes a latch connector, and the latch connector is latched and matched with the latch hole.

[0027] Therefore, by providing the snap-in hole and the snap-in connector, a detachable connection between the upper base assembly and the lower base assembly is achieved, thereby facilitating the disassembly and installation of the upper base assembly and the lower base assembly.

DETAILED DESCRIPTION

[0046] 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.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] Moreover, the Z-axis in the drawings represents the vertical direction, that is, the up and down position, and the positive direction of the Z-axis (that is, the direction of the arrow of the Z-axis) represents the top, and the negative direction of the Z-axis (that is, the direction opposite to the positive direction of the Z-axis) represents the bottom; the X-axis in the drawings represents the horizontal direction and is designated as the left and right positions, and the positive direction of the X-axis (that is, the direction of the arrow of the X-axis) represents the right side, and the negative direction of the X-axis (that is, the direction opposite to the positive direction of the X-axis) represents the left side; the Y-axis in the drawings represents the front and back positions, and the positive direction of the Y-axis (that is, the direction of the arrow of the Y-axis) represents the front side, and the negative direction of the Y-axis (that is, the direction opposite to the positive direction of the Y-axis) represents the back side; it should be noted that the aforementioned Z-axis, Y-axis and X-axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0049] The terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0050] like Figures 1 to 9As shown, this embodiment provides an air-conditioning indoor unit, including an upper base assembly 1, a fan assembly 2 and a lower base assembly 3, the fan assembly 2 is installed on the lower base assembly 3, the upper base assembly 1 and the lower base assembly 3 are detachably connected, and the lower base assembly 3 is rotatably connected to the upper base assembly 1, and the lower base assembly 3 has a first position for facilitating the operation of the fan assembly 2 and a second position for facilitating the removal of the fan assembly 2.

[0051] It should be noted that the fan assembly 2 may include a cross-flow fan and a driving mechanism for driving the cross-flow fan; it may also include an axial flow fan and a driving mechanism for driving the axial flow fan. A receiving portion is provided on the lower base assembly 3, and the fan assembly 2 is at least partially received in the receiving portion; the fan assembly 2 is fixed in the receiving portion by a connecting member. The upper base assembly 1 may be screwed or snap-fitted with the lower base assembly 3; the lower base assembly 3 may be rotatably connected to the upper base assembly 1 by a hinge or an axial hole connection. When the upper base assembly 1 is rotated to the first position relative to the upper base assembly 1, the upper base assembly 1 and the lower base assembly 3 are closed. At this time, the upper base assembly 1 and the upper base assembly 1 may be snap-fitted or screw-fastened, the air conditioner may perform normal cooling and heating operations, and the fan assembly 2 may perform normal blowing. When the fan assembly 2 is rotated to the second position, there is a certain degree of opening and closing between the upper base assembly 1 and the lower base assembly 3, which frees up the disassembly space of the fan assembly 2, and the fan assembly 2 can be disassembled at this time. When the fan assembly 2 needs to be disassembled, the lower base assembly 3 rotates downward to free up the disassembly space of the fan assembly 2, so as to realize the disassembly of the fan assembly 2.

[0052] The advantage of such a configuration is that, by installing the fan assembly 2 on the lower base assembly 3, the lower base assembly 3 is rotatably connected to the upper base assembly 1. When the fan assembly 2 needs to be disassembled and cleaned, the lower base assembly 3 can be rotated downward to make room for disassembling the fan assembly 2, thereby avoiding the overall disassembly of the lower base assembly 3 and the upper base assembly 1, thereby simplifying the disassembly and assembly steps of the fan assembly 2.

[0053] like Figures 1 to 5 As shown, the lower base assembly 3 includes a lower base 31 and a lower cover 32, the fan assembly 2 is installed on the lower base 31, the lower base 31 and the lower cover 32 are detachably connected, and the lower cover 32 is rotatably connected to the upper base assembly 1.

[0054] It should be noted that a receiving portion is provided on the lower base 31, and the fan assembly 2 is at least partially received in the receiving portion; the fan assembly 2 is fixed in the receiving portion through a connecting member; the lower base 31 and the lower cover 32 are screwed or clamped, and the lower cover 32 can be rotatably connected to the upper base assembly 1 by a hinge or an axial hole connection. When the fan assembly 2 needs to be disassembled, the lower cover 32 is rotated downward, and the lower base 31 rotates downward along with the lower cover 32 to make room for disassembly of the fan assembly 2, thereby realizing disassembly of the fan assembly 2. When the fan assembly 2 needs to be installed, the fan assembly 2 is first installed in the receiving portion, and then the lower cover 32 is rotated upward so that the lower cover 32 is closed with the upper base assembly 1, thereby realizing installation of the fan assembly 2.

[0055] In one embodiment, a receiving portion is provided on the upper base assembly 1, and the fan assembly 2 is at least partially received in the receiving portion, and the fan assembly 2 is fixed in the receiving portion by a connecting member. When the fan assembly 2 needs to be disassembled, the upper base assembly 1 is rotated upward to make room for disassembly of the fan assembly 2, thereby achieving disassembly of the fan assembly 2. When the fan assembly 2 needs to be installed, the fan assembly 2 is installed in the receiving portion, and then the upper base assembly 1 is rotated downward to close the lower cover 32 and the upper base assembly 1.

[0056] The advantage of such a configuration is that, by installing the fan assembly 2 on the lower base 31, the lower cover 32 is rotatably connected to the upper base assembly 1; when the fan assembly 2 needs to be disassembled, the lower base assembly 3 rotates along with the lower cover 32, avoiding the disassembly of the lower cover 32, thereby simplifying the disassembly and assembly of the fan assembly 2. Furthermore, through the detachable connection between the lower cover 32 and the lower base 31, when the lower base 31 needs to be disassembled and cleaned, the lower base 31 can be disassembled and assembled separately, thereby reducing the disassembly and assembly steps of the lower base 31.

[0057] like Figure 6 , Figure 7 , Fig.15 As shown, the lower base 31 includes a clamping ring 311, and the lower cover 32 includes a clamping column 322. The clamping ring 311 and the clamping column 322 are clamped and connected.

[0058] It should be noted that the position of the clamping column 322 corresponds to the position of the clamping ring 311. There are at least two clamping rings 311, and the number of the clamping columns 322 corresponds to the clamping ring 311. The clamping column 322 is provided with a limiting portion, and the opening width of the clamping ring 311 is smaller than the diameter of the limiting portion; the limiting portion is inserted into the clamping ring 311. The clamping ring 311 can be integrally connected to the lower base 31. The clamping column 322 can be integrally connected to the lower cover 32. When the lower base 31 is installed, the clamping column 322 is inserted into the clamping ring 311 along the opening direction of the clamping ring 311, and at this time, the limiting portion is coaxial with the clamping ring 311; when the lower base 31 needs to be disassembled, the lower base 31 can be pulled out along the clamping direction to achieve the disassembly of the lower base 31.

[0059] The advantage of such a configuration is that, through the clamping cooperation between the clamping column 322 and the clamping ring 311, when the lower base 31 needs to be disassembled, the lower base 31 can be directly pulled out along the clamping direction, thereby reducing the disassembly and assembly steps of the lower base 31, thereby facilitating the disassembly and assembly of the lower base 31.

[0060] like Figures 1 to 5 As shown, the upper base assembly 1 includes a first connecting arm 11, and the lower cover 32 includes a second connecting arm 321. The first connecting arm 11 is provided with a rotating shaft 111, and the second connecting arm 321 is provided with a rotating shaft connecting hole 3211. The rotating shaft 111 is rotatably connected to the rotating shaft connecting hole 3211.

[0061] It should be noted that the first connecting arm 11 can be arranged vertically or tilted, the first connecting arm 11 can be integrally connected to the upper base assembly 1 or detachably connected, there are at least two first connecting arms 11, and the number of the second connecting arms 321 corresponds to the first connecting arm 11; the rotating shaft 111 can be integrally connected to the first connecting arm 11 or detachably connected. The second connecting arm 321 can be arranged horizontally or tilted; the rotating shaft connecting hole 3211 is coaxial with the rotating shaft 111, and the rotating shaft 111 is plugged into the rotating shaft connecting hole 3211.

[0062] The advantage of such a configuration is that, through the configuration of the first connecting arm 11 and the second connecting arm 321, an escape space is formed between the lower cover 32 and the upper base assembly 1, so as to prevent the upper base assembly 1 from interfering with the rotation of the lower base 31 when the lower base 31 rotates following the lower cover 32. The first connecting arm 11 and the second connecting arm 321 are rotatably connected through the rotation shaft 111 and the rotation shaft connection hole 3211 to achieve the rotation connection between them.

[0063] like Figure 1, Figure 4 As shown, a tube hole 1111 is provided on the rotating shaft 111 , and the tube hole 1111 is coaxial with the rotating shaft connecting hole 3211 .

[0064] It should be noted that the pipe hole 1111 is coaxial with the shaft 111, and the pipe hole 1111 passes through the body of the shaft 111 along the axis of the shaft 111; the pipe hole 1111 can be used for the passage of the drain pipe 4, the connecting pipe or the power connection line. The advantage of such a setting is that by opening the pipe hole 1111 on the shaft 111, the drain pipe 4 can pass through the pipe hole 1111 to directly communicate with the interior of the air conditioner indoor unit, avoiding the need to disassemble the housing of the indoor unit when installing the drain pipe 4, thereby simplifying the installation of the drain pipe 4.

[0065] like Figure 5 , Fig.12 , Fig.13 As shown, a water receiving groove 312 is provided on the lower base 31, a drainage nozzle 3121 is provided on the water receiving groove 312, a water channel 3212 is provided on the second connecting arm 321, one end of the water channel 3212 is connected to the drainage nozzle 3121, and the other end of the water channel 3212 is used to communicate with the environment.

[0066] It should be noted that the water channel 3212 can be a curved pipe or a vertical pipe; the water channel 3212 can be threaded, interference-connected or plugged with the drain nozzle 3121; the water channel 3212 can be connected to the drain pipe 4 by threaded connection or plugging; or the water channel 3212 can be connected to the drain pipe 4 through a connecting pipe; the water channel 3212 is used to discharge the liquid in the water receiving tank 312. The water channel 3212 can be connected to the internal environment of the lower base 31, and can also be connected to the external environment of the lower base 31. The liquid in the water receiving tank 312 flows from the drain nozzle 3121 into the water channel 3212, and then is discharged through the drain pipe 4.

[0067] The advantage of such a configuration is that, by providing a water channel 3212 on the second connecting arm 321, the liquid in the water receiving groove 312 flows into the drain pipe 4 through the water channel 3212, and then is discharged through the drain pipe 4, thereby achieving the discharge of the liquid in the water receiving groove 312. The configuration of the water channel 3212 avoids direct connection between the drain pipe 4 and the drain nozzle 3121, thereby facilitating the disassembly and replacement of the drain pipe 4.

[0068] like Figure 5As shown, the indoor air conditioner further includes a drain pipe 4, which is suitable for passing through the pipe hole 1111 and communicating with the other end of the water channel 3212, and the drain pipe 4 is made of a hose.

[0069] It should be noted that the hose can be any one of a metal hose, a plastic hose or a rubber hose; the hose is plugged or threadedly connected to the waterway 3212. Therefore, when the lower cover 32 rotates downward, the drain pipe 4 made of a hose can reduce the obstruction of the drain pipe 4 to the rotation of the lower base assembly 3.

[0070] like Fig.12 As shown, the second connecting arm 321 is detachably connected to the lower cover 32 .

[0071] It should be noted that the detachable connection between the second connecting arm 321 and the lower cover 32 may be a snap connection or a threaded connection; the second connecting arm 321 may be located at the left and right sides of the lower cover 32 or at any other position where the second connecting arm 321 can be connected to the first connecting arm. The advantage of such a setting is that, by detachably connecting the second connecting arm 321 and the lower cover 32, when the lower base 31 needs to be disassembled, the second connecting arm 321 may be disassembled first to avoid the water channel 3212 obstructing the disassembly of the lower base.

[0072] like Figure 5 As shown, the disassembly direction of the lower base 31 relative to the lower cover 32 is the same as the axial direction of the drain nozzle 3121 .

[0073] It should be noted that the disassembly direction of the lower base 31 relative to the lower cover 32 refers to the movement direction of the lower cover 32 when it is disassembled from the lower base 31. In one embodiment, the lower cover 32 is snap-fitted with the lower base 31, and the direction in which the lower base 31 is snapped into the lower cover 32 is the same as the axial direction of the drain nozzle 3121. In one embodiment, the lower cover 32 is plug-fitted with the lower base 31, and the direction in which the lower base 31 is inserted into the lower cover 32 is the same as the axial direction of the drain nozzle 3121. When disassembling the lower base 31, the lower cover 32 is rotated downward, and when the lower cover 32 is rotated to a certain angle, the lower base 31 is disassembled along the axial direction of the drain nozzle 3121. When installing the lower base 31, the lower base 31 is connected to the lower cover 32 along the axial direction of the drain nozzle 3121. The advantage of such a configuration is that, by limiting the disassembly direction of the lower base 31 relative to the lower cover 32, when the lower base 31 is removed, the drain nozzle 3121 is coaxial with the water channel 3212, thereby preventing the water channel 3212 from interfering with the disassembly of the lower base 31.

[0074] like Fig.14 As shown, the air conditioner indoor unit further includes a wind sweeping blade assembly 323 , and the wind sweeping blade assembly 323 is installed on the lower cover 32 .

[0075] It should be noted that the wind sweeping blade assembly 323 is detachably connected to the lower cover 32, which can be specifically connected by screws or clamping. An air outlet is provided on the lower cover 32, and the position of the wind sweeping blade assembly 323 corresponds to the position of the air outlet; the wind sweeping blade assembly 323 is used to adjust the air outlet direction of the air outlet. The advantage of such a setting is that by arranging the wind sweeping blade assembly 323 on the lower cover 32, the wind sweeping blade assembly 323 is located on the lower side of the lower base 31. After the lower base 31 is disassembled, the wind sweeping blade assembly 323 can be further disassembled to facilitate the disassembly and cleaning of the wind sweeping blade assembly 323.

[0076] like Figures 8 to 9 As shown, the air conditioner indoor unit further includes an upper shell 6, which is connected to the upper base assembly 1, and the upper shell 6 is suitable for being enclosed with the lower cover 32 to form a space for accommodating the upper base assembly 1 and the lower base 31.

[0077] It should be noted that the upper shell 6 is detachably connected to the upper base assembly 1, which can be specifically connected by screws or clamping; when the lower base assembly 3 is in the first position, the upper shell 6 is fitted with the lower cover 32. When the lower base assembly 3 is in the second position, the upper shell 6 remains stationary and the lower cover 32 rotates downward. Thus, through the setting of the upper shell 6, the upper shell 6 and the lower cover 32 are combined to form the housing of the indoor unit, and the upper base assembly 1 and the lower base 31 are accommodated in the housing, thereby achieving the shielding of the upper base assembly 1 and the lower base 31.

[0078] like Figures 8 to 11 As shown, a latch hole 12 is provided on the upper base assembly 1 , and the lower base assembly 3 includes a latch connector 33 , and the latch connector 33 is latched and matched with the latch hole 12 .

[0079] It should be noted that the position of the clamping hole 12 corresponds to the position of the clamping connector 33; there are at least two clamping connectors 33; the number of the clamping holes 12 corresponds to the number of the clamping connectors 33; the clamping connector 33 can be integrally connected to the lower base 31, or the clamping connector 33 can be integrally connected to the lower cover 32. Thus, the detachable connection between the upper base assembly 1 and the lower base assembly 3 is achieved through the arrangement of the clamping hole 12 and the clamping connector 33, thereby facilitating the disassembly and installation of the upper base assembly 1 and the lower base assembly 3.

[0080] 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 invention shall be subject to the scope defined by the claims.
