Problems solved by technology

The problem of how to realize the recycling of water resources and saving water has long been a major issue of survival and development that human beings should be concerned about. This invention is aimed at the fact that water appliances that have been used by humans in large quantities are often not discovered in time because of their water leakage. The long-term loss of precious water sources has resulted in incalculable waste of water resources. In addition, some people have bad living habits. massive loss of resources
[0003] After searching the existing technical documents, it was found that Luan Donghua's paper entitled "Development of New Automatic Flushing Appliances and Water Conservation in Public Toilets" published in "Energy Saving" (No. 6, 2001) aimed at using mechanical timing flushing devices for general public toilets A new type of water-saving automatic flushing device structure design method is proposed based on the waste of water caused by fixed-time flushing of the urinal. Time interval, to avoid the waste of water caused by flushing in vain when no one is using the toilet, but this water-saving method is only to consider how to achieve the purpose of less water by reducing the frequency of water use, and does not solve the problem of water heaters. Problems of wasting water due to damaged parts or bad behavior of people

Embodiment Construction

[0031] The embodiments of the present invention are described in detail below: the present embodiment is implemented under the premise of the technical solution of the present invention, and detailed implementation and specific operation process are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0032]This embodiment is realized based on an electronic water-saving device, which includes: a solenoid valve, a differential pressure sensor, a conditioning amplifier, a signal processor, a crystal oscillator, a memory, a bidirectional thyristor, a learning switch, a reset switch and a power adapter . Among them, the solenoid valve is installed at the upstream end of the water supply valve of the water heater. The electric coil of the solenoid valve is powered by a single-phase AC power supply controlled by a bidirectional thyristor. The differential pressure sensor obtains the water flow differential pressure si...

Abstract

This invention relates to one electrical water save control method in clean ware technique field, which comprises the following steps: firstly setting once maximum time for the device; then through flow sensor and set water device for one use in comparison of the maximum time to judge and control the water waste situations; once there is water leakage through electron water save control method computation to timely judge whether to start magnetic valve on output control volume to close water path to indicate person in simple form to diode with leakage situations.

Description

technical field [0001] The invention relates to a water-saving method in the technical field of sanitary ware, in particular to an electronic water-saving control method. Background technique [0002] With the rapid growth of world economy and population, the consumption of water resources in the world is also increasing at an alarming rate. The problem of how to realize the recycling of water resources and saving water has long been a major issue of survival and development that human beings should be concerned about. This invention is aimed at the fact that water appliances that have been used by humans in large quantities are often not discovered in time because of their water leakage. The long-term loss of precious water sources has resulted in incalculable waste of water resources. In addition, some people have bad living habits. massive loss of resources. [0003] After searching the existing technical documents, it was found that Luan Donghua's paper entitled "Devel...
