Zero cold water control system and method and readable storage medium

Abstract

The invention relates to the technical field of zero cold water heater transformation, in particular to a zero cold water control system and method and a readable storage medium. The zero cold water control system comprises a cold and hot water intercommunicating pipe, a temperature detector, a signal emitter and a host, and the cold and hot water intercommunicating pipe is connected to hot water pipe outlets and cold water pipe outlets of a plurality of water consumption points communicating with a water heater; the temperature detector is connected with the cold and hot water communicating pipe and used for measuring the temperature of water in the hot water pipe; the signal emitter is electrically connected with the temperature detector, when the temperature detector detects that the water temperature is larger than a set value, the signal emitter emits a first signal, and when the temperature detector detects that the water temperature is lower than the preset value, the signal emitter emits a second signal; and the host comprises a circulating pump and a controller, the controller is electrically connected with the circulating pump, the circulating pump is connected to a cold water pipe of the water heater, and the controller is in communication connection with the signal transmitter. Compared with the prior art, zero cold water control over the multiple consumption points is achieved, the safety performance is better, the user experience is improved, and the practicability of zero cold water transformation is improved.

Description

technical field [0001] The invention relates to the technical field of transformation of zero-cooled water heaters, in particular to a zero-cooled water control system, a control method and a readable storage medium. Background technique [0002] The transformation of zero-cold water heater refers to the transformation of the original water heater without zero-cold water function, so that the hot water pipeline does not need to wait for hot water to come out directly when in use, which saves the waiting time for users to use water, especially in cold winter. Improved user experience. [0003] In related technologies, most of the transformation methods for water heaters that do not have zero cold water function are to add a small heater with instant heating function to the hot water pipe at the water outlet of the water end. When the faucet is turned on, the cold water in the hot water pipe Instant heating, when it is detected that the hot water flowing out of the water heat...

Problems solved by technology

[0004] However, the above-mentioned instant small heater also has defects. On the one hand, the power of the small heater is too large, generally around 3000-5000 watts. It cannot meet its power consumption demand, and there are potential safety hazards. How to realize the zero-cooling water function at multiple water points has become an urgent problem to be solved
