The Structure Improvement And Development Of Washing-Drying Integral Machine

The washing-drying integral machine is a new type of intelligent washing machine,which is based on the whole automatic washing machine and integrates the functions of washing,spin-dry and drying.As an ordinary consumer appliances are accepted by consumers.Product appearance is very important,the user experience is also very important.In the paper,a washing-drying integral machine is studied,including the appearance of the product and the operation of the main control board design.Improvement of existing structure optimization.Structure optimization of drying and condensing system.When the product design should consider the problem of sagging,improved door hinge,front plate structure,increase front panel and door hinge reinforcing member.Optimization of inner and outer tube structure,include:design of the wall thickness around the rear bearing seat of the outer cylinder 7mm,inner tube ring material using SUS4302 B delta 0.6mm.Bearing model selection 6205,6206,high speed forging and cold rolling process,the three foot reinforcement from the axis to the top,triangular array structure.Analysis of the causes of noise,the frequency conversion motor is used to reduce the high frequency noise,innovative front panel connector design,improvement of shock absorber bracket structure,optimal design of damping system.System test results: washing noise 43.79 dB,70.09 dB dehydration noise,drying noise 59.75 dB.The drying heating pipe is made up of two kinds of power.It can achieve three kinds of power high,medium and low.The system is equipped with 3 temperature controllers and 3 temperature sensors.The precise control of the inlet temperature can fluctuate within a small range.System drying moisture content range: Cotton test load(-1~+2.2%);easy to handle fabric test load(0.6~+3.8%).Three dimensional water cooled condensation system.It can be fully exchanged with cold water and hot and humid air.Reducing system cycle wind temperature.The filter net device is placed in the condenser at the lower part of the blower,? hrough the filter to prevent the dust into the fan impeller and drying heating pipe surface.The filtering net device is fixed on the back cover of the box body.Remove the filter screen without opening the box.Through the optimization and improvement of the structure,the problem of the observation window sagging and the strength of inner and outer tubes are solved,and the washing and dewatering noise is reduced.Drying system,the application of double power drying heating tube,high,medium and low three power control,accurate temperature control,reduce the drying noise.The three-dimensional water cooling condensation system realizes the full exchange of the cold water spray and the hot and humid air,so as to achieve the reasonable matching of the drying and condensing system,and the moisture content of the drying rate is up to the standard.The filtering net device is designed to protect the fan and the drying heating pipe effectively.
