Technical field
The present invention relates to the fan electromotor technical field of detachable wall hanging type air conditioner indoor unit, be that a kind of drive division has three equally distributed contact-making surfaces specifically, axial-flow fan is rotated keep stable, reduce the fan electromotor of the detachable wall hanging type air conditioner indoor unit of noise.
Background technology
Air conditioner is the device that indoor air temperature is remained on optimum state, can create pleasant environment in the summer of sweltering heat.Along with the raising of people to the environment requirement and the level of consumption, the demand of air conditioner constantly increases.
Air conditioner is arranged at one according to indoor set and off-premises station and still divides to be arranged and be divided into one-piece type and separation type.Integral air conditioner is that indoor set and off-premises station is integrated, burrows on the wall in house or installs on window, and Saperated air conditioner is divided into indoor set and off-premises station.It is cabinet type, wall-hanging, embedded etc. that Saperated air conditioner is divided into again.
Behind the hot-air, allow it and low temperature refrigerant carry out heat exchange in the air conditioner suction chamber,, freeze indoor to indoor discharge cold air; Perhaps operate on the contrary, heat indoor.
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of prior art wall-hanging indoor unit of air conditioner; Fig. 2 is the fan electromotor structural representation of prior art detachable wall hanging type air conditioner indoor unit; Fig. 3 is the structural representation of drive division in the fan electromotor of prior art detachable wall hanging type air conditioner indoor unit.
As shown in Figure 1, indoor set is formed by the front support frame 20 of chassis 10 and 10 fronts, chassis, and forms the space that a plurality of parts are installed between chassis 10 and the front support frame 20.
The bottom of suction panel 30 has the long front suction of lateral length to go into grid 32, and air can be from going into indoor set inside for the spatial flow of air conditioning thus.Lower central at suction panel 30 is provided with display part 34, and display part 34 is expressed the air conditioner operating state, so the user can confirm the operating state of air conditioner by display part 34.
Be set between suction panel 30 and the front support frame 20 filter and go into the filter 40 that grid 32 flows into the air of indoor set inside, and heat exchanger 50 is installed at the rear of support 20 in front by front suction.Heat exchanger 50 is for the inflow air that makes indoor set carries out heat exchange, and the air after filter 40 filters carries out heat exchange.
Axial-flow fan 60 is installed at rear at heat exchanger 50, axial-flow fan 60 is accepted revolving force and is rotated from the fan electromotor 70 that is installed on right-hand end, make indoor air stream go into indoor set inside, and carry out simultaneously again to the effect of indoor discharge at the air of heat exchanger 50 heat exchanges.
Frame 62 restriction that is fixed of the left-hand end of axial-flow fan 60 is moved, its right-hand end combines with fan electromotor 70 in motor cover 70 ' inner rotation, axial-flow fan 60 can rotate, and the air of indoor set inside is by the indoor discharge of discharge grid 80 pilot flow directions of axial-flow fan 60 downsides thus.
Be set to guide the blade 82 and the louver board 84 of discharging the grid 80 air-outs flow direction at the opposite side of discharging grid 80, promptly the air-out that is guided by blade 82 up and down two directions change and flow to, and air according to the left and right sides reciprocating motion of louver board 84 to the left and right two directions change and flow to.
Be provided with protection network 85 in the back of louver board 84, protection network 85 is connected with suction grid screw by four connecting holes of its upper end.
The inner right side space electrical equipment installation portion on chassis 10 is provided with controller assemblies 90 for 12 li, controller assemblies 90 is vitals of air conditioner, the printed circuit board (PCB) 92 that comprises the running of control indoor set and off-premises station is engaged in inside to printed circuit board (PCB) 92 and prevents that printed circuit board (PCB) 92 from avoiding the shell 94 of external impact.After printed circuit board (PCB) 92 inserts electrical equipment installation portion 12, shell 94 is installed, printed circuit board (PCB) 92 is positioned at shell 94 inside, avoids external impact, and is protected.
In addition, in the place ahead of controller assemblies 90, promptly the front, right side of front support frame 20 is provided with rectangular controller lid 24, and controller lid 24 can insert mouthful 22 separation from the lid of front support frame 20 for convenient for maintaining when controller assemblies 90 breaks down.
As Fig. 2, shown in Figure 3, the fan electromotor 70 of detachable wall hanging type air conditioner indoor unit comprises: motor 11 and motor driving shaft 13, motor driving shaft 13 is drawn by the rotor position, it can rotate under the drive of motor 11 and transfer torque, thereby the front end at motor driving shaft 13 is provided with a contact-making surface 15 formation drive divisions 14, and drive division 14 is connected with axial-flow fan 60, for axial-flow fan provides power, when motor 11 runnings, drive axial-flow fan and rotate, allow air to flow into indoor set inside.
But, there is following not enough point in the aforesaid prior art:
The drive division of motor driving shaft front end is provided with a contact-making surface, drive division and axial-flow fan match to merge and drive the axial-flow fan rotation, but, because contact-making surface has only one, in driven by motor axial-flow fan rotating process, torque concentrates on this contact-making surface, and the center of gravity of drive division itself does not drop on the axle center of rotor, cause the rotation imbalance of motor driving shaft, the wearing and tearing of motor have been strengthened, cause axial-flow fan disalignment when rotating accordingly, produce abnormal sound, shortened the useful life of fan electromotor and axial-flow fan simultaneously.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of drive division and has three equally distributed contact-making surfaces, axial-flow fan is rotated keep stable, reduces the fan electromotor of the detachable wall hanging type air conditioner indoor unit of noise.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The fan electromotor of detachable wall hanging type air conditioner indoor unit of the present invention, comprise: motor and motor driving shaft, motor driving shaft is drawn by the rotor position, it can rotate under the drive of motor and transfer torque, thereby the front end at motor driving shaft is provided with contact-making surface formation drive division, and the drive division of motor driving shaft front end comprises three equally distributed contact-making surfaces.
The present invention can also adopt following technical measures:
Cylinder by motor driving shaft between described three contact-making surfaces connects.
The top of described drive division is processed as the heap physique structure.
Advantage and good effect that the present invention has are:
The drive division of the motor driving shaft front end of the fan electromotor of detachable wall hanging type air conditioner indoor unit comprises three equally distributed contact-making surfaces among the present invention, when motor driving shaft matches with axial-flow fan, the center of gravity of drive division drops on the axle center of rotor, three contact-making surfaces have on average been born the conduction of torque, motor driving shaft and axial-flow fan can stably be in shaft core position when rotating, reduce to move noise, prolonged the useful life of fan electromotor and axial-flow fan.
