Energy-saving environment-friendly intelligent flushing toilet and control method thereof

Abstract

The invention provides an energy-saving environment-friendly intelligent flushing toilet and a control method thereof. The flushing toilet includes an infrared sensor, an excrement detection sensor, an excrement smashing system and a PLC. When a user comes in front of the toilet or sits on the toilet, the infrared sensor can detect the existence of the user, the PLC can carry out memory storage, and after the detected information indicating the existence of the user disappears, the PLC can fast scan information detected by the excrement detection sensor to determine the existence of excrementon the basis of whether there is excrement passing by a close position of the front side of the excrement detection sensor, and then the PLC accordingly makes decision on whether there is excrement, automatically selects flushing water amount for flushing and enables the excrement smashing system to fast smash the excrement at the same time. When there is a person passing by the toilet, a time delay function is achieved to avoid flushing by mistake. The flushing toilet is made of energy-saving environment-friendly materials and adopts soft elbow pipes for water sealing, can solve the problem that the distances from drain ports of restrooms to backwalls are not uniform, and can become one of energy-saving environment-friendly water-saving toilets of a new era.

Description

technical field [0001] The invention relates to a flush toilet (here mainly refers to a toilet), which is mainly made of energy-saving and environment-friendly materials, can identify urine and stool, can break stool, can realize flushing after defecation, and can automatically select the amount of flushing water Intelligent flushing toilet and its control method. Background technique [0002] In the current flush toilet (referring to the current toilet), most of the flushing methods are still realized by manually pressing the mechanical button, and its fully automatic flush toilet, especially the automatic flush toilet used in the family Water toilets, so far, have not seen reports about the actual objects and practical applications; although some places use automatic flushing in public places, they are mainly men's urinals, which are not satisfactory from the perspective of their application effects , its dissatisfaction lies in "unintelligent" and "non-water-saving"; Ju...

AI Technical Summary

Problems solved by technology

As far as the current flush toilets are concerned, regardless of their appearance, their materials are almost all made of "ceramic" materials. Everyone knows that ceramic materials need to be fired at high temperatures, and the firing process is very energy-consuming, and the combustion exhaust gas It will also cause serious pollution to the environment, and the whole process of its ceramic materials from mining, crushing to tire making is very polluting to the environment; as far as the product made from it - the ceramic toilet itself, its life cycle should be several thousand years Above, even immortal! However, in actual family use, it is found that its average service life is less than 10 years. In terms of its replacement reasons, it is nothing more than the following: one is the "U-shaped tube" inside, especially for water seal, due to its long service life. "The internal scale is thicker, which causes its diameter to become smaller, resulting in poor flushing, and the current existing descaling technology is powerless, so it has to be replaced; the second is because the toilet is constructed. The distance between the wall and the distance from the toilet drain to the back is not consistent. During the installation, the acceptance personnel specifically required that the back of the toilet must be against the wall, so that the installer ignored the misalignment between the toilet outlet and the toilet drain, and blindly placed the back of the toilet against the wall. , resulting in poor flushing of the toilet, and the occupants do not know the reason, and mistakenly think that it is a problem with the toilet itself and replace the toilet; third, when new customers move into second-hand housing or the old house is refurbished, the old toilet is often replaced Replacement; Fourth, in order to follow the trend or pursue beauty, some people insist on replacing the original toilet

[0005] Through search and query, it is found that there are already many patents on flush toilets, but it is clearly stated that they are made of non-ceramic materials, can detect whether there is someone or not, can identify toilets, can break stools, can have the function of selecting the amount of flushing water and The automatic flush has not been found yet
