Embodiment Construction

[0025] The method for judging water inflow to a washing machine and the washing machine provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] see figure 2 Shown is the preferred embodiment of the present invention. The washing machine is powered on, and starts after setting the program. When the program is set to execute the process before water intake, such as fault diagnosis, weighing, etc., this process is executed first. Then, the water inlet valve is opened to start water intake, and the water level value is detected. The program is set to read 60 numbers per second, and every 30 seconds is used as the set time range for calculating the slope of the water level change line.

[0027] In this embodiment, the values ​​are set as follows:

[0028] After entering the water for 30 seconds, judge whether the water is normal;

[0029] The water intake time is t=120 seconds, and the water level is continuous...

Abstract

The invention discloses a washing machine inflow judging method and a washing machine applying the method. The method comprises the following steps of: presetting a standard slope value Kb(i) of a water level changing curve which varies along with inflow time in a washing machine computer program controller, starting inflow, and starting detection of a water level value; continuously acquiring the water level value in a set time range, processing according to the least square method to form a water level variation line, thus a slop value Ki of a water level changing line is obtained; and judging inflow condition by comparing the slope value Ki of the water level changing curve with the standard slope value Kb(i) and sending a message. By adopting the technical scheme, the washing machine can detect abnormal condition at any time in an inflow process, an alarm can be given timely, a user can be guaranteed to timely solve the inflow problem, and washing can be guaranteed to be carried out smoothly.

Description

technical field [0001] The invention relates to a method for judging the water inlet of a washing machine, in particular to a method capable of judging the water inlet situation at any time by comparing the slope of the water inlet water level change line with a set slope and a washing machine using the method. Background technique [0002] Household electric washing machines are divided into pulsator washing machines, drum washing machines, and stirring washing machines. When the washing machine is filled with water, it will be affected by the water pressure or the temporary water cut-off, which will cause the washing machine to be filled with water for an overtime and affect the normal operation of the washing machine. [0003] There are two methods for the existing water inflow overtime alarm. One traditional solution: set the corresponding water inflow level and set a water inflow time period. examine. This water inflow detection scheme is adopted by most washing machi...
