Problems solved by technology

[0002] In the process of delivering hot water to the shower or faucet after the existing water heater has set the temperature, the cold water in the middle of the pipeline needs to be drained before it can be used, and if other water terminals are opened during use, it will As a result, the temperature of hot water flowing to the shower or faucet suddenly rises or falls, seriously affecting the user's experience of using the water heater, and because the water temperature of the hot water pipe and the cold water pipe will change with the seasons, the power of the water heater and other factors Therefore, the temperature represented by the angle of the wrench of the water heater will change with the change of the external conditions under different circumstances, and the shower water temperature required by the user is relatively fixed, so it is necessary to design an intelligent water heater temperature adjustment for energy-saving water heaters. The control device and method solve the problem of recycling the cold water in the middle of the pipeline and the water flow below the set temperature threshold variation range to the water heater for reuse, and at the same time, the water inlet temperature that can sense the twist angle of the wrench is intelligently linked with the set temperature Adjust so that the temperature of the hot water flowing to the shower or faucet is always within the threshold variation range of the set temperature

Abstract

The invention discloses an intelligent control device and method for temperature adjustment of a water-saving water heater. The three-way wrench piece comprises a three-way connector and a wrench connected into the three-way connector in a rotating fit mode. A solenoid valve; a shower head; a temperature display; when the processing unit judges that the temperature detected by the third temperature sensor is larger than or equal to the preset water outlet temperature of the shower head, the processing unit sends a water supply signal to the electromagnetic valve to enable the electromagnetic valve to be communicated with the shower head, and then water is supplied to the shower head; otherwise, the processing unit sends a water supply stopping signal to the electromagnetic valve to disconnect the electromagnetic valve from the shower head, the backflow pipeline is connected, and the water flows back to the water heater. Cold water in the middle of the pipeline and water flow lower than the set temperature threshold value change range can be recycled into the water heater to be reused, intelligent linkage adjustment is conducted on the water inlet temperature sensing the twisting angle of the wrench and the set temperature, and the effect that the temperature of hot water flowing to a shower head is always within the set temperature threshold value change range is achieved.

Description

technical field [0001] The invention relates to an intelligent control device and method for temperature adjustment of a water-saving water heater, belonging to the technical field of intelligent control. Background technique [0002] In the process of delivering hot water to the shower or faucet after the existing water heater has set the temperature, the cold water in the middle of the pipeline needs to be drained out before it can be used. The temperature of the hot water flowing to the shower or faucet suddenly increases or decreases, which seriously affects the user's experience of using the water heater. Moreover, the water temperature of the hot and cold water pipes will change with the seasons, the power of the water heater and other factors. Therefore, the temperature represented by the angle of the water heater wrench will change with the change of the external conditions in different situations, and the shower water temperature required by the user is relatively f...
