Abstract
The invention discloses a weighing method of a rolling drum washing machine driven by an asynchronous motor. According to the invention, an asynchronous motor is used in the rolling drum washing machine. The specific method comprises the following steps that a motor controller controls a motor to accelerate at the constant torque, and the angle formed by rotation from the initial speed to the set measuring speed is measured; then the motor controller controls the motor to drop from the measuring speed to the initial speed in a free state, and the angles formed by the fact that the motor rotates in the speed reduction process are measured; the inertness of load J is acquired according to a formula; and then the weight of load W is acquired according to a corresponding relation in a fitting table. The method provided by the invention has the advantages of rapid weighing speed, high accuracy, low cost and simple structure, can implement intelligent operation with software, and is convenient to use.
Description
Technical field
The present invention relates to roller washing machine, particularly a kind of clothing of roller washing machine of Induction Motor-Driven method of weighing.
Background technology
Roller washing machine is that motor is a power, drives to washing tube through belt and belt pulley and rotates.Present roller washing machine all has certain intelligence control system, and motor is driven by motor driver, and the whole washing machine is controlled by the master controller system.
According to developing direction, roller washing machine develops to energy-saving and environmental protection more, intelligentized direction.Intelligent weighing is exactly a developing direction, and for weighing of clothing, weighing before the washing can let washing machine automatically select suitable water level, washing agent injected volume and do not need user's operation, also energy-conserving and environment-protective; Before dehydration, weigh, can revise the disequilibrium survey of washing machine, improve dehydrating effect according to the weight that records.Present roller washing machine has automatic function of weighing, much all is to accomplish through sensor, and cost is higher, complex structure.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of the described existing scheme of weighing automatically of background technology, design a kind of clothing Weighing method that utilizes computing method to realize.
The present invention is based on the washing machine that uses Induction Motor-Driven.
Concrete grammar is: the motor controller controls motor quickens with constant torque, measures the angle that turns over the measuring speed process from initial velocity to setting; Control motor again and drop to initial velocity with free state, measure the angle that motor turns in the reduction of speed process from measuring speed; According to formula
Said match form is:
| 1000J | 122 | 128 | 137 | 150 | 157 | 173 | 181 | 189 | 229 | 235 | 238 | 315 | 319 | 333 |
| W | 0 | 0.5 | 1 | 2 | 2.5 | 3.5 | 4 | 4.6 | 7.14 | 7.64 | 8.24 | 14.28 | 14.78 | 15.38 |
Described initial velocity is preferably 90rpm, and measuring speed is 120-130rpm.
Method of the present invention is weighed to clothing, and process is no more than 15s than very fast; Motor speed in the test process is not high, off-centre can not occur and seriously hit bucket.And the present invention has considered the structural system friction, so can reject deviation, precision is higher.
Description of drawings
Fig. 1, sequential chart of the present invention;
Fig. 2, process flow diagram of the present invention;
Fig. 3, match form of the present invention.
Embodiment
Calculate inertia J, the corresponding relation according to match form shown in Figure 3 obtains clothes weight.
Embodiment one; Setting initial velocity
is 90rpm; Measuring speed
is 120rpm, and the angle that motor turns in the accelerator
is; The angle that turns in the moderating process
is.The inertia J of coming out that converts is.Inquiry match form obtains clothes weight and is.
Embodiment two; Setting initial velocity
is 90rpm; Measuring speed
is 120rpm, and the angle that motor turns in the accelerator
is; The angle that turns in the moderating process
is.The inertia J of coming out that converts is.Inquiry match form obtains clothes weight and is.
According to the above clothes weight that measures, feed back to the master controller of washing machine, the control inflow that can respond, the washing parameters such as automatic injected volume of washing agent, the intelligent degree of raising washing machine.And whole measurement and computation process, can need not people's participation by automatic completion of master controller through the software programming mode, accurately convenient.
Claims (2)
1. based on the Weighing method of the roller washing machine of Induction Motor-Driven, said roller washing machine uses asynchronous machine; Concrete grammar is: the motor controller controls motor quickens with constant torque, measures the angle that turns over the measuring speed process from initial velocity to setting; Control motor again and drop to initial velocity with free state, measure the angle that motor turns in the reduction of speed process from measuring speed; According to formula
。
2. the Weighing method of described roller washing machine based on Induction Motor-Driven according to claim 1, it is characterized in that: said initial velocity is 90rpm, measuring speed is 120 ~ 130rpm.
