Description
Technical field
The present invention relates to washing machine field, specifically a kind of washing machine leak determination methods and its washing machine.
Background technology
With the improvement of people's living standards, requirement of the people to washing machine day by day increases with expectation.It is desirable to oneself
Maloperation can be judged by machine and be reminded in time, to avoid causing wasting, even endanger.Washing machine is expected simultaneously
It is more intelligent, it is also safer, to reduce the operation of people and realize more preferable clean result.
Water lev el control technology has been commonly used on washing machine now, pressure type sensor has been generally used.Using pressure type water
The washing machine of level sensor controlling water level is realized generally by following methods:Air pressure in outer barrel upper chamber after detection water inlet
Power changes, and sends the result to single-chip microcomputer, and single-chip microcomputer changes into corresponding SEA LEVEL VARIATION value the change of pressure, is judged
Water inlet water level is simultaneously controlled.During adopting said method, due to drum head sectional area it is larger, so if water inlet is without water inlet,
Need the long period accurately could judge, then alert notice user.If washing machine failure causes leak, slight leak computer
Plate may can't detect, and leak effectively causes the waste of a large amount of water, or even the damage of article.
To solve the above problems, it is proposed that many solutions, for example:
The Chinese patent of Application No. 200810000761 ---《A kind of washing machine water position detecting method and its device》, its

Value.
Further, described revision water level L3 is drawn according to influence coefficient A is corresponding with clothes weight Q by control system
Water level value;Described clothes weight Q is to measure clothes weight Q by weighing system, and the clothes weight Q for measuring is transmitted to control
System processed;Described influence coefficient A is to pre-set impact coefficient in the controls.
Further, described influence coefficient A is divided into the corresponding storage respectively of different coefficient values according to different medicated clothing materials
For A1、A2... An, after user selects medicated clothing material, control system calls corresponding coefficient value An according to the medicated clothing material of washing,
And coefficient of utilization value An draw to should medicated clothing material and clothes weight Q revision water level L3.
Further, when the medicated clothing of washing of drum type washing machine various material composition, control system is according to the corresponding system of various materials
Numerical value An and washing medicated clothing quality Q correspond to out the corresponding water level value of various materials respectively, and control system judges each described
Minima in water level value, and described minima is set as revising water level L3.
A kind of washing machine with washing machine water position detecting method as above, including flow of inlet water measurement apparatus, use
In realizing the control of washing machine, detection, show and warning function control system, water level in medicated clothing weighing system and detection outer barrel
Condensate tank of dehumidifier.
Further, the condensate tank of dehumidifier includes the collection chamber being connected with outer barrel of washing machine and for detecting collection chamber
The pressure type water level sensor of interior pressure change.
The invention has the beneficial effects as follows:
By flow of inlet water measurement apparatus are arranged between water intaking valve and water inflowing box, washing machine is allow accurately to count in time
Calculate into the water yield in washing machine.
It is compared by water level L1 and actual water level L2 will be calculated, makes washing machine increased water leakage detecting function, so as to
Avoid big harm is caused because of outer barrel of washing machine leak.
By said apparatus and method, the degree of accuracy of leak judgement is improve, shorten the feedback time of leak judgement, from
And time of user has been saved, improve the work efficiency of washing machine.
