Description
Technical field
The utility model belongs to the washing machine technical field, more particularly relates to the design that utilizes the suspension rod weight sensor to detect the washing machine of laundry amounts and inflow.
Background technology
The weight of present common computer automatic washing machine (laundry amounts and inflow) sensing mode mainly contains following two kinds: a kind of is Panasonic's mode, and the self induction electromotive force that it utilizes motor to produce when shutting down detects.The laundry amounts of in washing machine, placing not simultaneously, the inertia of motor is just different, the number of turns that motor rotates after outage is also just different.So the self induction electromotive force curve that motor produces after outage is just had any different certainly.The manner promptly is to utilize the pulse number of self induction electromotive force to distinguish the laundry amounts of washing.Another kind is Hitachi's mode, and it is to install tachometer generator on power transmission shaft, the laundry amounts of in washing machine, placing not simultaneously, the inertia of motor is also different, the revolution that motor rotates after outage is just different.The manner promptly is to distinguish the laundry amounts of washing according to the difference of revolution.
Above-mentioned weight detecting mode has following shortcoming: accuracy of detection depends on the uniformity (under the identical situation of suffered resistance, motor is because the self induction electromotive force that inertia produces needs basically identical) of motor.For the bel-drivenn washing machine, testing result is also relevant with the tension force of belt.Under the situation that clothes weight is identical in interior bucket, when the belt tension tension, the weight of judgement can be bigger than actual weight; When belt tension was crossed pine, the weight of judgement can be littler than actual weight.Because belt is aging, in use, belt is pine more and more.Therefore, the weight of the clothing of judging with above-mentioned detection mode can be more fewer and feweri than actual weight, and its error is bigger.
The purpose of this utility model just is to overcome above-mentioned shortcoming, provides a kind of weight detecting result not rely on the uniformity of motor and the degree of aging of driving belt, judges that the higher suspension rod weight sensor that utilizes of precision detects the washing machine of laundry amounts and inflow.
Summary of the invention
In order to achieve the above object, the utility model comprise casing at least, be installed in guidance panel and hanger rod part on the casing, hang base plate on hanger rod part, be installed in interior bucket on the base plate and outer barrel and machine driven system, be installed in the culvert system in the casing and be installed in casing and guidance panel on computerized control system.Computerized control system comprise at least single-chip microcomputer and respectively with button inputting circuits, signal deteching circuit, zero crossing circuitry, display circuit, buzz circuit, output driving circuit and the power circuit of single-chip microcomputer interconnection.Hanger rod part comprises gooseneck bracket, suspension rod, pop-up, damping spring and subiculum at least.Weight sensor also is installed on the hanger rod part, and weight sensor is connected with single-chip microcomputer, and signal deteching circuit comprises weight sensor.
Weight sensor can be installed between the compression face of the upper end of suspension rod and gooseneck bracket.
Weight sensor can also be installed between the bottom surface of the lower end of suspension rod and subiculum.
Weight sensor also can be installed between the compression face of the upper end of damping spring and pop-up.
Weight sensor can also be installed between the compression face of the lower surface of damping spring and subiculum.
Hanger rod part that is damping part.Gooseneck bracket is placed on four angle stiffeners of casing.Whole damping part is suspended on the casing by the total weight of gooseneck bracket with outer bucket parts.Pop-up hangs on the outer bucket, the weight of bearing whole outer bucket.The weight that pop-up is born passes on the subiculum by damping spring.Along with the weight conversion of outer bucket parts, the power difference that damping spring is subjected to, the length of spring just can change.The position that can experience the changes in weight of outer bucket on the suspension rod has everywhere: between the upper end of suspension rod and the compression face of gooseneck bracket, between the bottom surface of the lower end of suspension rod and subiculum, between the compression face of the upper end of damping spring and pop-up and between the compression face of the lower surface of damping spring and subiculum.Therefore, in above-mentioned one of position everywhere a metal film pressure sensor (weight sensor) is installed, the changes in weight of outer bucket makes metal film pressure sensor institute stressed just different, and its resistance also just changes.Computerized control system provides the voltage of DC5V to weight sensor, detects the electric current of the weight sensor of flowing through, and is laundry amounts and the inflow of placing in the outer bucket of decidable according to the variation of resistance or current value.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of weight detecting result not rely on the uniformity of motor and the degree of aging of driving belt, detects, judges that the higher suspension rod weight sensor that utilizes of precision detects the washing machine of laundry amounts and inflow.It can be widely used in the various full-automatic pulsator washing machines.
