Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0032] Such as figure 1 As shown, a method for detecting fouling of water heaters and giving an alarm indication provided by the present invention includes the following steps:

[0033] a. Install a water quality sensor and a temperature compensation sensor in the inner tank of the water heater to detect the water quality signal of the water heater and the temperature compensation signal around the water quality sensor;

[0034] b. Process the detected water quality signal and temperature compensation signal, and perform analog-to-digital conversion on the processed signal;

[0035] c. The converted signal is input to the single-chip microcomputer (IC), and the temperature compensation module in the single-chip microcomputer (IC) performs temperature compensation calculation on the signal to correct the resistance value of the water under different water temperatures...

Abstract

The invention relates to a method for detecting water heater scaling and making alarming indication. In the method, the water quality of water used in a water heater is judged by detecting the water quality, the time periods of scaling under different water quality and the scaling degree of the corresponding period can be analyzed according to a judging result, and a user can be timely prompted. Therefore, the user can learn and master the current service condition and the scaling degree of the water heater, and judges whether to clean an inner container and remove scales in real time. According to the invention, not only is the service life of the water heater greatly prolonged, but also the use safety is improved for the user; and the user can timely clean the inner container to remove the scale so as to effectively prevent potential safety hazards on water utilization due to the polluted water in the inner container.

Description

technical field [0001] The invention relates to a method for detecting fouling of a water heater and giving an alarm indication. Background technique [0002] For electric water heaters, fouling has always been an important hidden danger that affects the service life of water heaters and the safety of users. How to effectively solve the problems caused by scaling has become an intuitive and important issue for the development of electric water heaters. In electric water heaters, when the water temperature is generally heated to 40°C, fouling tends to occur, and when heated to 60-70°C, the scaling speed is obviously accelerated. Water with a slow flow rate is more likely to scale, and the flow of water in the water heater is extremely slow, and the scaling speed will be faster. These scales are as hard as stones, but the ability to transfer heat is very poor, which is less than 1% of iron or glass. These scales will continue to increase, and many adverse consequences will o...
