Washing machine water inletting monitoring method

Abstract

The invention discloses a washing machine water inletting monitoring method, which comprises the following steps: resetting a timer before letting water in, judging whether a washtub is empty or water level is lower than set water level, starting to let water in after fuzzily judging and weighing clothes weight if the washtub is empty, executing a washing program if the water level reaches the set water level, starting to let water in if the water level does not reach the set water level, the timer starting to time after water is let in, detecting whether the water level rises or not in a settime to judge whether water inletting is normal or not, alarming if the water level does not rise or the water level rise cannot satisfy preset conditions in the set time, otherwise continuously letting water in and circulating the steps, and stopping letting water in when the water level reaches the set water level, or executing water inletting overtime alarm if water inletting time reaches total set time but the inlet water does not reach the set water level. The invention has the advantages that the water level variation is dynamically detected when water is let in to judge whether the water inletting state is normal or not, the water inletting is cut off and the alarm is given to inform the user if the water inletting state is not normal, and the situation of time wastage caused by waiting for washing under the condition of no inlet water is avoided.

Description

technical field [0001] The invention relates to a washing machine water inlet method, in particular to a washing machine water inlet monitoring method capable of judging whether the water inlet is normal. Background technique [0002] The current water inlet control of washing machines mostly adopts the method of directly entering water from the water inlet valve to the set water level. If the water pressure is low or the user forgets to turn on the faucet, an alarm will be issued at the set water inlet control time, such as 15 minutes or 30 minutes. The time can be changed according to the model. Although this method is simple, the control of the water intake process is relatively rigid. If the water pressure is too low, such as in rural areas or areas with insufficient water supply pressure and places that use water tanks for water supply, it will If the set water intake time, such as 15 minutes or 30 minutes, fails to reach the set water level, the alarm will be triggered...

AI Technical Summary

Problems solved by technology

[0005] The above method judges whether the water intake is appropriate by comparing the actual water intake time with the set parameters of the set water intake time. However, this test is a fixed test. If the water pressure is unstable, the test result will have a large error
