Hot water constant temperature constant-current automatic regulating apparatus

Abstract

The invention relates to an automatic adjusting device of the constant temperature and constant current for hot water, which is suitable for the automatic adjustment of the water temperature and the flow, because the flow can not be controlled by the prior similar products, a certain waste is caused to the resource and the energy. The automatic adjusting device comprises a flow controlling motor, an adjusting motor for the mixing ratio of the cold water and the hot water, a flow sensor, a temperature controlling valve, an adjusting valve for the mixing ratio of the cold water and the hot water and a microcomputer controller. The flow sensor and the temperature sensor are arranged at the mixed water outlet opening part of the cold water and the hot water, according to the electrical signal sent by the flow sensor and the temperature sensor, the microcomputer controller can drive and control the flow controlling motor and the adjusting motor for the mixing ratio of the cold water and the hot water, to drive the valve cores of the flow controlling valve and the adjusting valve for the mixing ratio of the cold water and the hot water, to automatically adjust the flow and the temperature of the hot water, thereby, the purpose of the constant temperature and constant current is achieved, and the consumption of the resource and the energy can be saved.

Description

technical field

[0001] The invention relates to a hot water constant temperature and constant flow automatic adjustment device, in particular to a hot water constant temperature and constant flow automatic adjustment device which saves water and makes hot water use more efficient. Background technique

[0002] The temperature control of hot water during bathing generally adopts the following methods:

[0003] 1. Manually control the mixing ratio of cold water and hot water to control the outlet temperature of hot water.

[0004] 2. Use the physical properties of thermal expansion and contraction of certain materials to adjust the temperature ratio of cold water and hot water to control the outlet water temperature. Be 87215790 as Chinese Patent No., the name is called shower water temperature automatic stabilizing device.

[0005] 3. Use microcomputer technology such as single-chip microcomputer to sample and compare the temperature at the mixing outlet, drive the reversib...
