Description

TECHNICAL FIELD

[0001] The utility model relates to the field of domestic water, especially to a system for intelligent regulation and control of domestic water to prevent dead water. BACKGROUND

[0002] Drawbacks of prior art:

[0003] I. In the traditional domestic cold water system, studies have shown that when the water temperature is between 25° and 55° and the water does not flow for a long time (e.g. when the occupants are away for a long time), bacteria, viruses and mold can easily grow in the water pipes, further corroding the inner walls of the pipes. When the occupants return, they can open the faucets to drain the water, but this is subject to human control and may be forgotten. However, the corrosion of the inner walls of the pipes cannot be avoided. There is currently no effective automatic control solution on the market.

[0004] II. In the traditional domestic hot water system, hot water is supplied by electric boilers and solar water heaters, and the water temperature in the main pipes is set relatively high. However, the actual water demand of each hot water branch pipe cannot be dynamically adjusted, and the outlet temperature can only be manually adjusted. For example, when taking a shower, the user needs to manually adjust the temperature for half a day. The user cannot dynamically adjust the temperature of each branch pipe according to their own needs to ensure a constant temperature outlet. Therefore, the user's comfort cannot be guaranteed.

[0005] III. In the traditional domestic cold water system, to prevent the backflow of bacteria, viruses, harmful gases and odors into the indoor space, a water trap is often designed at the lower part of the washbasin in the bathroom, the floor drain in the bathroom, the vegetable basin in the kitchen, and the floor drain on the balcony. When there is water, it can effectively prevent the backflow of odors from the sewer into the indoor space. However, when the occupants are away for a long time and no one is at home, the water in the water trap will evaporate gradually, causing the backflow of odors (especially in summer, when evaporation is faster). There is currently no effective automatic control solution on the market. The user relies on the frequency of water use to ensure that the water trap has enough water. This manual control method has many uncertainties and cannot effectively ensure that the water trap can store water, leading to the backflow of bacteria, viruses, harmful gases and odors from the sewer into the indoor space, which may cause cross-infection and discomfort to the user in terms of olfactory and physical health.

[0006] With the progress of society and technology, water systems are becoming increasingly important in modern building construction. We have gradually moved from the previous "water is available" to the current pursuit of health, comfort and home intelligence. The traditional system has the above-mentioned three drawbacks.

[0007] In view of the above three shortcomings, the prior art solutions are all manual intervention, which cannot preserve the time effectiveness and has many shortcomings. In view of the above three shortcomings, it is urgent to develop a household water intelligent control system to solve the above three technical problems. Utility model content
