Description

Technical Field

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

[0002] After using the air conditioner for a period of time, the internal components will accumulate dust and become dirty, especially the air ducts and fan blades on the base of the air conditioner. Once they become dirty, they will have adverse effects on the health of the air conditioner users. Therefore, regular cleaning of the air ducts and fan blades is the key to ensuring healthy use of the air conditioner.

[0003] Before cleaning the fan blades, the fan blades need to be disassembled from the air conditioner. However, the existing air conditioner has many complicated processes and steps when disassembling and assembling the fan blades. Summary of the invention

[0004] The problem solved by the invention is that the fan blade disassembly and assembly procedures of the existing air conditioner are numerous and complicated, and the operation is difficult.

[0005] To solve the above problems, the present invention provides an air conditioner, comprising: an upper base, a lower base and a fixing frame, wherein the fixing frame is connected to the upper base, and the lower base is provided with fan blades and fan blade fixing members, and the fan blade fixing members include an elastic baffle assembly and a motor, wherein the upper base is detachably connected to the lower base, the fan blades are detachably connected to the motor, the elastic baffle assembly and the motor are fixedly connected to the fixing frame, and the fixing frame is fixedly connected to the upper base.

[0006] By providing an elastic baffle assembly, when an external force is applied toward the elastic baffle assembly in the axial direction of the fan blade, a yielding displacement can be provided, so that the fan blade undergoes axial displacement, thereby providing a structural basis for achieving the effect of easy disassembly of the fan blade; by connecting the fan blade fixing parts, including the motor and the elastic baffle assembly, to the fixing frame, not only can a relatively stable position of the fan blade in the air conditioner be achieved, but also the motor can be fixed in the original position after the fan blade is disassembled without the need for disassembly, and has no effect on the electrical integrity and subsequent cleaning, thereby effectively avoiding the troubles caused by disassembling the motor and terminals and cleaning and waterproofing of the existing easy-to-disassemble air conditioner.

[0007] Optionally, the elastic baffle assembly is connected to the motor, and the motor is connected to the fan blade.

[0008] By connecting the elastic baffle assembly to the motor, the motor transmits the external force to the elastic baffle assembly losslessly, and transmits the displacement of the elastic baffle assembly losslessly to the fan blade, ensuring that the fan blade undergoes axial displacement under the axial external force.

[0009] Optionally, the fixing frame includes a first fixing frame and a second fixing frame, the elastic baffle assembly and the motor are connected to the first fixing frame, the first fixing frame, the elastic baffle assembly and the motor constitute a supporting structure at one end of the fan blade, the other end of the fan blade is connected to the second fixing frame, and the second fixing frame constitutes a supporting structure at the other end of the fan blade.

[0010] By respectively arranging a first fixing frame and a second fixing frame at both ends of the fan blade, and combining the first fixing frame with fan blade fixing parts such as a motor and an elastic baffle assembly to form a support structure at one end of the fan blade, and using the second fixing frame as a support structure at the other end of the fan blade, the position of the fan blade is fixed, the stability of the position of the fan blade in the air conditioner is ensured, and the stability and reliability of the air conditioner structure are ensured.

[0011] Optionally, the elastic baffle assembly includes a cover plate, an elastic member and a motor mounting seat, the motor is placed in the motor mounting seat and fixed, and the cover plate is connected to the first fixing frame.

[0012] By setting a cover plate connected to the first fixing frame, the position of the elastic baffle assembly relative to the air conditioner is fixed or limited to a certain position range, thereby realizing the position limitation and support function of the elastic baffle assembly on the fan blade. By setting an elastic member, when the elastic baffle assembly is subjected to an axial external force of the fan blade toward the elastic baffle assembly, the elastic member is compressed to produce a yielding displacement, and the fan blade moves axially accordingly. When the moving distance is greater than a certain value, the other end of the fan blade is separated from the second fixing frame, so that the fan blade can be easily taken out.

[0013] Optionally, the maximum displacement of the elastic baffle assembly is n, and the amount of fit between the fan blade and the second fixing frame is m, wherein n and m satisfy: n>m. This ensures that after the fan blade pushes the motor to move a distance of m toward the elastic baffle assembly, the end of the fan blade away from the elastic baffle assembly is disengaged, and then the fan blade can be taken out in the radial direction, thereby achieving easy disassembly of the fan blade.

[0014] Optionally, the fan blade fixing member further includes a bearing rubber ring seat assembly, the fan blade is connected to the bearing rubber ring seat assembly, and the bearing rubber ring seat assembly is connected to the second fixing frame.

[0015] A bearing rubber ring seat assembly is provided to connect the fan blade to the second fixing frame, thereby fixing the position of the fan blade. At the same time, the bearing rubber ring seat assembly and the fan blade have an interference fit. When the fan blade is subjected to an external force toward the elastic baffle assembly and axially displaced toward the elastic baffle assembly, the fan blade is separated from the bearing rubber ring seat assembly, and the fan blade can easily break away from the position limitation of the fan blade fixing part, thereby achieving easy disassembly of the fan blade.

[0016] Optionally, the lower base further includes an air duct component, and the air duct component is connected to the fixing frame.

[0017] By connecting the fan blades and the air duct components to the fixing frame respectively, the positions of the fan blades and the air duct are ensured to remain relatively unchanged, thereby effectively ensuring the integrity of the structural system of the air duct components.

[0018] Optionally, the air duct component includes a cavity, the fan blade matches the contour of the cavity, and the fan blade is placed in the cavity, thereby ensuring the integrity of the structural system of the air duct component.

[0019] Optionally, the fixing frame is a movable component, and when the fixing frame extends relative to the upper base, the upper base and the lower base are separated, and when the fixing frame retracts relative to the upper base, the upper base and the lower base are closed.

[0020] The upper base and the lower base are separated and closed by the movement of the fixing frame. When disassembling, the upper base and the lower base are separated by the fixing frame, and the fan blades are pushed and pulled out along the axial direction. After the fan blades are removed, the travel space is made, and the air duct can be disassembled, thereby realizing the simple disassembly and assembly of the air duct and the fan blades.

[0021] Optionally, the fixing frame includes a fixing frame body, a mechanical arm and an eagle beak structure, the fixing frame body is slidably connected to the upper base, the mechanical arm is connected to the fan blade fixing piece, and the eagle beak structure is connected to the air duct component.

By setting a mechanical arm, the fan blades and the duct components can be fixed respectively. By setting the eagle beak structure, the duct components can be easily disassembled.

[0023] Optionally, the motor is an outer rotor motor.

[0024] By setting up an outer rotor motor, the motor and the fan blade can be directly interference connected without the need for screws or other tools. When disassembling the fan blade, the fan blade can be taken out by simply pushing and pulling it. When installing the fan blade, the fan blade can be installed by simply pushing and pulling it, thereby achieving portable disassembly and assembly of the fan blade.

[0036] The terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0037] The present invention provides an air conditioner.

[0038] Figure 1 Schematic diagram of an embodiment of the present invention in which the upper base 1 and the lower base 2 of the air conditioner are separated. Figure 1In one embodiment of the present invention, the air conditioner includes: an upper base 1, a lower base 2 and a fixing frame 3, the fixing frame 3 is connected to the upper base 1, and the lower base 2 is provided with a fan blade 4 and a fan blade fixing member 5, and the fan blade fixing member 5 includes an elastic baffle assembly 51 and a motor 52, wherein the upper base 1 is detachably connected to the lower base 2, the fan blade 4 is detachably connected to the motor 52, the elastic baffle assembly 51 and the motor 52 are fixedly connected to the fixing frame 3, and the fixing frame 3 is fixedly connected to the upper base 1.

[0039] Among them, the fixing frame 3 and the upper base 1 are fixedly connected or detachably connected. After the fixing frame 3 is connected to the upper base 1, the position between the fixing frame 3 and the upper base 1 is relatively fixed, or the fixing frame 3 can be moved within a certain range relative to the upper base 1. For example, in one embodiment, the fixing frame 3 is a telescopic rod connecting the upper base 1 and the lower base 2. When the fixing frame 3 extends relative to the upper base 1, the upper base 1 and the lower base 2 are separated. When the fixing frame 3 retracts relative to the upper base 1, the upper base 1 and the lower base 2 are closed.

[0040] The lower base 2 is provided with a fan blade 4 and a fan blade fixing member 5, wherein the fan blade 4 is a cross-flow fan blade 4. The fan blade fixing member 5 is used to fix the fan blade 4 at a specific position of the air conditioner, and the fan blade fixing member 5 includes an elastic baffle assembly 51 and a motor 52, and the elastic baffle assembly 51 and the motor 52 are both arranged along the axial direction of the fan blade 4, and the elastic baffle assembly 51 and the motor 52 can be arranged at the same end of the axial direction of the fan blade 4, and can also be arranged at different ends of the axial direction of the fan blade 4, wherein, in addition to fixing the position of the fan blade 4, the motor 52 is also used to provide rotational kinetic energy for the fan blade 4, and the elastic baffle assembly 51 provides a displacement when receiving an external force in the axial direction of the fan blade 4 toward the elastic baffle assembly 51, so that the fan blade 4 undergoes an axial displacement, providing a structural basis for realizing the effect of easy disassembly of the fan blade 4.

[0041] The setting of the elastic baffle assembly 51 allows the fan blade 4 to be removed by simply pushing and pulling on the fan blade 4, without removing the motor 52. In one embodiment, the motor 52 is an outer rotor motor, and the fan blade 4 is interference-connected with the motor 52 through the fan blade shaft. When the axial displacement of the fan blade 4 is greater than a certain value, the fan blade shaft is separated from the motor 52, and the fan blade 4 and the motor 52 are released from the interference connection. Since the motor 52 and the fan blade 4 are not connected by screws, there is no need to loosen the screws, and the connection between the fan blade 4 and the motor 52 can be released by directly pushing and pulling the fan blade 4.

[0042] In one embodiment, the elastic baffle assembly 51 and the motor 52 are arranged at different ends of the fan blade 4, the elastic baffle assembly 51 is connected to one end of the fan blade 4, and the motor 52 is connected to the other end of the fan blade 4. When an external force toward the elastic baffle assembly 51 is applied to the fan blade 4, and the axial displacement of the fan blade 4 is greater than a certain value, the fan blade 4 is separated from the motor 52, and the connection with the motor 52 is released, and then the fan blade 4 can be taken out. At this time, the motor 52 can be arranged to be connected to the fixing frame 3, and after the fan blade 4 is removed, the motor 52 is fixed in the original position without removal.

[0043] The fan blade fixing part 5 is used to fix the position of the fan blade 4, and the fan blade fixing part 5 is connected to the fixing frame 3. The fixing frame 3 is a component directly connecting the air conditioner and the fan blade fixing part 5, which can limit the fan blade fixing part 5 to a specific position or a specific position range, thereby indirectly limiting the position of the fan blade 4 or the movable position range of the fan blade 4, thereby limiting the position of the fan blade 4 in the air conditioner, ensuring the stability of the fan blade component inside the air conditioner, and ensuring the stability and integrity of the overall structure of the air conditioner.

[0044] When disassembling the duct fan blades, first separate the upper base from the lower base. After the upper base is separated from the lower base, the fan blades are exposed. At this time, an external force is applied to the fan blades in the axial direction of the fan blades and toward the elastic baffle assembly 51, so that the end of the fan blade away from the elastic baffle assembly is detached from the fixation, thereby realizing the disassembly of the fan blades. After the fan blades are disassembled, since the motor is fixed on the fixing frame and the fixing agent is fixed on the upper base, the fan blades can be easily removed without disassembling the motor.

[0045] Optionally, the elastic baffle assembly 51 is connected to the motor 52 , and the motor 52 is connected to the fan blade 4 .

[0046] For specific examples, please refer to Figure 2 , Figure 2 1 is an exploded view of each embodiment of the present invention including a fan blade 4, a fan blade fixing member 5 and a fixing frame 3. The elastic baffle assembly 51 and the motor 52 are arranged at the same end of the fan blade 4, one end of the motor 52 is directly connected to the end of the fan blade 4, and the elastic baffle assembly 51 is connected to the other end of the motor 52 to support and fix the position of the fan blade 4.

[0047] By connecting the elastic baffle assembly 51 to the motor 52, the motor 52 transmits the external force to the elastic baffle assembly 51 losslessly, and transmits the displacement of the elastic baffle assembly 51 losslessly to the fan blade 4, ensuring that the fan blade 4 is axially displaced by the axial external force.

[0048] The maximum displacement of the elastic baffle assembly 51 is n, and the matching amount between the fan blade 4 and the fixing frame 3 or other fan blade fixing member 5 is m, wherein n and m satisfy: n>m.

[0049] After the elastic baffle assembly 51 and the motor 52 are installed in place, after a certain force is applied externally, the motor 52 can move a distance n (n>m, m is the matching depth between the end of the fan blade 4 away from the motor 52 and the fixing frame 3 or other fan blade fixing parts 5) along the axial direction of the fan blade 4. When the fan blade 4 pushes the motor 52 to move a distance m toward the elastic baffle assembly 51, the end of the fan blade 4 away from the elastic baffle assembly 51 is disengaged, and then the fan blade 4 can be taken out in the radial direction.

[0050] Alternatively, if Figure 2 The fixing frame 3 includes a first fixing frame 31 and a second fixing frame 32. The elastic baffle assembly 51 and the motor 52 are connected to the first fixing frame 31. The first fixing frame 31, the elastic baffle assembly 51 and the motor 52 constitute a supporting structure for one end of the fan blade 4. The other end of the fan blade 4 is connected to the second fixing frame 32. The second fixing frame 32 constitutes a supporting structure for the other end of the fan blade 4.

[0051] The first fixing frame 31 and the second fixing frame 32 are respectively arranged at two ends of the fan blade 4 in the axial direction, and the fan blade 4 is supported and fixed by connecting with the fan blade fixing member 5. Optionally, in order to improve the stability and reliability of the fixing frame 3, the first fixing frame 31 and the second fixing frame 32 are connected as a whole, and specifically, the first fixing frame 31 and the second fixing frame 32 can be connected as a whole at the part of the upper base 1.

[0052] The motor 52 and the elastic baffle assembly 51 are arranged at the same end of the fan blade 4, one end of the motor 52 is directly connected to the end of the fan blade 4, the other end of the motor 52 is connected to one end of the elastic baffle assembly 51, and the other end of the elastic baffle assembly 51 is connected to the first fixing frame 31, that is, the elastic baffle assembly 51 is arranged between the motor 52 and the first fixing frame 31, and the first fixing frame 31 is connected to the base 1, so that the first fixing frame 31, the elastic baffle assembly 51, and the motor 52 connected in sequence constitute a supporting structure at one end of the fan blade 4.

[0053] Among them, the elastic baffle assembly 51 and the first fixed frame 31 can be detachably connected or fixedly connected, and there is no specific limitation on the connection method. However, after the elastic baffle assembly 51 is connected to the first fixed frame 31, the position of the elastic baffle assembly 51 is limited to a fixed position or moves within the fixed position range.

[0054] The other end of the fan blade 4 is connected to the second fixing frame 32. Optionally, a bearing structure is provided on the second fixing frame 32, and the second fixing frame 32 is connected to the fan blade 4 through the bearing structure.

[0055] Alternatively, if Figure 2The fan blade fixing member 5 also includes a bearing rubber ring seat assembly 53, the fan blade 4 is connected to the bearing rubber ring seat assembly 53, and the bearing rubber ring seat assembly 53 is connected to the second fixing frame 32.

[0056] The bearing rubber ring seat assembly 53 includes a bearing rubber ring seat and a bearing, the second fixing frame 32 includes a bearing hole, the bearing hole is used to install the bearing rubber ring seat, the bearing is arranged in the bearing rubber ring seat, and the fan blade 4 is indirectly connected to the second fixing frame 32 through the bearing rubber ring seat assembly 53. The fan blade 4 is interference fit with the bearing rubber ring seat assembly 53 through the fan blade rotating shaft.

[0057] A bearing rubber ring seat assembly 53 is provided to connect the fan blade 4 to the second fixing frame 32, thereby fixing the position of the fan blade 4. At the same time, the bearing rubber ring seat assembly 53 is interference fit with the fan blade 4. When the fan blade 4 is subjected to an external force toward the elastic baffle assembly 51 and axially displaced toward the elastic baffle assembly 51, the fan blade 4 is separated from the bearing rubber ring seat assembly 53, and the fan blade 4 can easily break away from the position limitation of the fan blade fixing member 5, thereby achieving easy disassembly of the fan blade 4.

[0058] By respectively setting a first fixing frame 31 and a second fixing frame 32 at both ends of the fan blade 4, and combining the first fixing frame 31 with the fan blade fixing parts 5 such as the motor 52 and the elastic baffle assembly 51 to form a support structure at one end of the fan blade 4, and using the second fixing frame 32 as a support structure at the other end of the fan blade 4, the position of the fan blade 4 is fixed, the stability of the position of the fan blade 4 in the air conditioner is ensured, and the stability and reliability of the air conditioner structure are ensured.

[0059] Alternatively, if Figure 2 The elastic baffle assembly 51 includes a cover plate 511 , an elastic member 512 and a motor mounting seat 513 . The motor 52 is fixed in the motor mounting seat 513 . The cover plate 511 is connected to the first fixing frame 31 .

[0060] The elastic member 512 is disposed between the cover plate 511 and the motor mounting seat 513 , one end of the elastic member 512 is connected to the cover plate 511 , and the other end of the elastic member 512 is connected to the motor mounting seat 513 .

[0061] The cover plate 511 is connected to the first fixing frame 31. After the cover plate 511 is connected to the first fixing frame 31, when subjected to external force, the cover plate 511 and the first fixing frame 31 do not move relative to each other, that is, the cover plate 511 is used to stabilize the position of the elastic baffle assembly 51. Optionally, the cover plate 511 and the first fixing frame 31 are integrally formed. Optionally, as Figure 6The cross-sectional view of the fan blade 4, the fan blade fixing member 5 and the fixing frame 3 of the air conditioner of the present invention, the cover plate 511 can be set as a hollow cylindrical object with a certain depth, one end of the cover plate 511 is a sealed end and the other end is an open end, the elastic member 512 is connected to the bottom plate of the sealed end of the cover plate 511 through the open end of the cover plate 511, the elastic member 512 and the motor mounting seat 513 are subjected to an external force in the axial direction of the fan blade 4 and in the direction of the cover plate 511, the elastic member 512 and the motor mounting seat 513 retract toward the sealed end of the cover plate 511, when the external force is removed, the elastic member 512 rebounds, and the elastic member 512 and the motor mounting seat 513 extend in a direction away from the sealed end of the cover plate 511, when the depth of the cover plate 511 is greater than a certain value, the cover plate 511 also has the protective functions of the elastic member 512, the motor mounting seat 513 and the motor 52, such as dust prevention, obstacle prevention, etc. Among them, the cover plate 511 can be a cylindrical object.

[0062] The elastic member 512 provides displacement reserve for the fan blade 4 based on its elastic property. When the fan blade 4 is subjected to an axial external force toward the elastic baffle assembly 51, the elastic member 512 is compressed to produce a displacement, and the fan blade 4 moves axially accordingly. When the moving distance is greater than a certain value, the other end of the fan blade 4 is separated from the second fixing frame 32, so that the fan blade 4 can be easily taken out. Optionally, the elastic member 512 is a spring.

[0063] Among them, Figure 7 The cross-sectional view of the fan blade 4, the fan blade fixing member 5 and the fixing frame 3 of the air conditioner of the present invention, the maximum displacement of the elastic baffle assembly 51 is n (the net expansion and contraction amount of the elastic member 512), and the matching amount of the fan blade 4 and the second fixing frame 32 is m, wherein n and m satisfy: n>m. Because only when the maximum displacement n of the elastic baffle assembly 51 is greater than the matching amount m of the fan blade 4 and the second fixing frame 32, the fan blade 4 is likely to be separated from the second fixing frame 32 by external force. Therefore, in order to ensure that the fan blade 4 is easy to disassemble, n>m is set in the design. Optionally, in order to take into account the smooth disassembly and assembly and the size of the whole machine, a disassembly margin of 5 to 20 mm is set, that is, nk≥m, 5mm≤k≤20mm.

[0064] The motor mounting seat 513 is used to connect with the motor 52, and the motor mounting seat 513 can be a circular ring mounting seat. The elastic member 512 can be directly connected to the motor mounting seat 513, such as connecting the elastic member 512 to the motor mounting seat 513 by means of clamping, screw connection or welding, or the elastic member 512 can be indirectly connected to the motor mounting seat 513. Optionally, the elastic baffle assembly 51 also includes a fixing plate 514, which is arranged between the elastic member 512 and the motor mounting seat 513, one end of the elastic member 512 is connected to the fixing plate 514, and the fixing plate 514 is connected to the motor mounting seat 513, thereby realizing the fixed connection between the elastic member 512 and the motor mounting seat 513. Among them, the connection method between the elastic member 512 and the fixed plate 514, and the fixed plate 514 and the motor mounting seat 513 is not limited here, but after the elastic member 512 and the fixed plate 514, and the fixed plate 514 and the motor mounting seat 513 are connected, the fixed plate 514 and the motor mounting seat 513 can transmit the external force from the fan blade 4 to the elastic member 512, and move with the movement of the elastic member 512, so as to transmit the displacement of the elastic member 512 to the fan blade 4, so that the fan blade 4 moves with the movement of the elastic member 512, thereby ensuring that the fan blade 4 is easy to disassemble.

[0065] Optionally, the lower base 2 further includes an air duct component 6 , and the air duct component 6 is connected to the fixing frame 3 .

[0066] Among them, Figure 1 , 3 and Figure 5 The fan blades 4 and the air duct component 6 are respectively connected to the fixing frame 3, so that the positions of the fan blades 4 and the air duct can be relatively unchanged, and the integrity of the structural system of the air duct component 6 is effectively guaranteed.

[0067] Optionally, the fixing frame 3 includes a first fixing frame 31 and a second fixing frame 32, and the first fixing frame 31 and the second fixing frame 32 are arranged at both ends of the fan blade 4, and cooperate with the fan blade fixing member 5 to serve as a supporting structure and a position limiting structure of the fan blade 4. At the same time, the first fixing frame 31 and the second fixing frame 32 are also arranged at both ends of the air duct component 6, serving as a supporting structure and a position limiting structure of the air duct component 6.

[0068] The fan blade 4 is not directly connected to the air duct component 6 , and the positions of the fan blade 4 and the air duct component 6 are limited simultaneously only by the first fixing frame 31 and the second fixing frame 32 , so as to achieve relative fixation of the positional relationship between the fan blade 4 and the air duct component 6 .

[0069] In addition, the fan blade fixing part 5, including the motor 52 and the elastic baffle assembly 51, are not connected to the air duct component 6. When the fan blade 4 and the air duct are disassembled, the fan blade 4 and the air duct can be directly disassembled, and the fan blade fixing part 5, such as the motor 52, is fixed on the fixing frame 3, that is, the motor 52 is still retained on the upper base 1, which has no effect on the electrical integrity and subsequent cleaning, and effectively avoids the troubles caused by the disassembly of the motor 52 and the terminal and the cleaning and waterproofing of the existing easy-to-disassemble air conditioner.

[0070] Alternatively, if Figure 3 The air duct component 6 includes a cavity 61, the fan blade 4 matches the cavity 61 profile, and the fan blade 4 is placed in the cavity 61 (such as Figure 1 ).

[0071] After the air duct component 6 and the fan blade fixing member 5 are connected to the fixing frame 3 respectively, and the fan blade 4 and the fan blade fixing member 5 are assembled, that is, when the air conditioner is in normal working state, the fan blade 4 is placed in the cavity 61 (such as Figure 1 ).

[0072] The fan blade 4 is not directly connected to the air duct component 6, but the fan blade 4 and the air duct component 6 are both connected to the fixing frame 3. Under normal working conditions, after the fan blade 4 and the fixing frame 3 are connected, the positions of the fan blade 4 and the fixing frame 3 are relatively fixed. After the air duct component 6 and the fixing frame 3 are connected, the positions of the air duct component 6 and the fixing frame 3 are relatively fixed. Therefore, under normal working conditions, after the fan blade 4, the air duct component 6 and the fixing frame 3 are connected, the positions of the fan blade 4 and the air duct component 6 are relatively fixed. A cavity 61 is provided on the air duct component 6 to accommodate the fan blade 4, thereby ensuring the integrity of the structural system of the air duct component 6.
