As a preferred option, the washing machine is equipped with communication device, and server prestores clothes weight G- motor's for washing machine
Optimum start-up voltage V- motor's for washing machine to reach the table of comparisons of T the time required to rated speed after optimum start-up voltage starting,
Washing machine obtains the information of the table of comparisons by communication device and server communication.
After adopting the above technical scheme, the present invention has the advantage that reaching specified turn after starting by motor's for washing machine
Be compared to the time required to fast with T to judge motor's for washing machine this starting voltage it is whether suitable, and then decide whether to washing
The starting voltage of clothing machine motor next time is adjusted, and tend to motor's for washing machine can constantly from after starting for the first time with corresponding practical
Optimum start-up voltage under loading condiction starts, and such motor's for washing machine can correspond to different negative when starting first time
Lotus condition automatically selects different starting voltage, enables motor's for washing machine suitably to start voltage starting, improves laundry
The working efficiency of machine motor, makes motor's for washing machine more efficiently work, and reduces the fever damage of motor heating loss and control loop
Consumption, and the case where motor starting fails under heavy load conditions can be led to avoid because motor running generates heat.
Specific embodiment
The present invention provides a kind of motor's for washing machine starting control method, including the following contents: prefabricated clothes weight G- laundry
The optimum start-up voltage V- motor's for washing machine of machine motor is to reach pair of T the time required to rated speed after optimum start-up voltage starting
According to table, detection motor's for washing machine arrives rated speed required time after starting every time be Tx, starts voltage with each by comparing Tx
The difference △ Tx of corresponding T adjusts starting voltage when starting motor's for washing machine next time, and x is positive integer, motor's for washing machine the
The starting voltage of one-shot is determined according to the clothes weight detected in washing machine.
The optimum start-up voltage V- motor's for washing machine of clothes weight G- motor's for washing machine after optimum start-up voltage starting to reach
The table of comparisons to rated speed required time T is counted according to test data of experiment, before washing machine factory just
It completes.Clothes weight refers to dispensing to the clothes weight in washing machine, and machine testing clothes weight of doing washing is the prior art, this
In repeat no more.For the clothes weight G washed every time, motor's for washing machine has corresponding optimum start-up voltage, theoretical
Best applications may be implemented with optimum start-up voltage starting in upper motor's for washing machine, can reduce energy consumption, improve service life.But
The clothes weight detected can and actual clothes weight there is certain deviation, therefore the actual starting voltage meeting of motor's for washing machine
And optimum start-up voltage, there are deviation, the present invention carries out the time required to reaching rated speed after starting by motor's for washing machine with T
Compare judge motor's for washing machine this starting voltage it is whether suitable, and then decide whether the starting to motor's for washing machine next time
Voltage is adjusted, and tend to motor's for washing machine can constantly from after starting for the first time to correspond to most preferably opening under the conditions of actual load
Dynamic voltage starts, and such motor's for washing machine can correspond to different loading condictions when starting first time to automatically select not
Same starting voltage, enables motor's for washing machine suitably to start voltage starting, improves the working efficiency of motor's for washing machine, make
Motor's for washing machine more efficiently works, and reduces the heating loss of motor heating loss and control loop, and can to avoid because
Motor running generates heat and leads to the case where motor starting fails under heavy load conditions.
In order to which whether starting voltage when determining starting motor's for washing machine next time needs to be adjusted, prestore and difference △ Tx
The 0 < B of value range A~B, A < being compared does not adjust starting electricity when starting motor's for washing machine next time if A≤△ T≤B
Pressure, if △ Tx < A, washing machine reduces the starting voltage of starting motor's for washing machine next time, if △ Tx > B, washing machine increases laundry
The starting voltage of starting machine motor next time.In general, A=-0.8~-0.3, B=0.3~0.8, such as A=-0.5, B=0.5,
If △ Tx=0.1, the starting voltage of adjustment starting motor's for washing machine next time is not needed, if △ Tx=0.6, increases washing machine
The starting voltage of starting motor next time, △ Tx=-0.7 then reduce the starting voltage of starting motor's for washing machine next time.
In order to ensure the validity and reliability of starting voltage adjustment, the starting voltage of motor's for washing machine is adjusted every time
Voltage change be equal, i.e., rise high starting voltage every time or to drop the voltage change that is adjusted of low start voltage all equal.
It should be understood that in order to make start voltage adjustment more quickly in place, can allow washing machine reduce washing machine horse
When the starting voltage reached, the value of voltage change and △ Tx/A meet proportional relation, i.e. △ Tx/A is bigger, and voltage change is got over
Greatly, for △ Tx/A closer to 1, voltage change is smaller.Same reason, washing machine is in the starting voltage for increasing motor's for washing machine
When, the value of voltage change and △ Tx/B meet proportional relation, i.e. △ Tx/B is bigger, and voltage change is bigger, and △ Tx/B more connects
It is bordering on 1, voltage change is smaller.
In the present invention, the optimum start-up voltage V- motor's for washing machine of clothes weight G- motor's for washing machine is with optimum start-up electricity
The table of comparisons of T can be pre-stored in washing machine the time required to reaching rated speed after pressure starting.It can also be arranged on washing machine
Communication device, server prestore the optimum start-up voltage V- motor's for washing machine of clothes weight G- motor's for washing machine with optimum start-up electricity
Reach the table of comparisons of T the time required to rated speed after pressure starting, washing machine is obtained pair by communication device and server communication
According to the information of table.
In addition to above preferred embodiment, there are other embodiments of the invention, and those skilled in the art can be according to this
Invention makes various changes and modifications, and as long as it does not depart from the spirit of the invention, should belong in claims of the present invention and determines
The range of justice.
