Description

An intelligent energy-saving single water tank constant temperature continuous hot water supply unit

technical field

The invention relates to a hot water supply unit, in particular to an intelligent energy-saving single water tank constant temperature continuous hot water supply unit.

Background technique

In the process of daily bathing and bathing, we often encounter the trouble of hot and cold water temperature. In mild cases, colds and hot stimuli may cause colds while taking a bath, and in severe cases, it may cause slipping or even burns. And there will be such an experience: at the beginning, let off a lot of cold water and sometimes stop bathing temporarily, and will be scalded or frozen when the shower nozzle is turned on again. At this time, we usually let off superheated or supercooled water, which not only affects the comfort of bathing, but also wastes a lot of water and energy.

In general, the solution to water temperature fluctuations is to constantly adjust the hot water supply volume knob during the bathing process to reach a new cold and hot water balance point when the water temperature is higher or lower than the desired water temperature. But when the water pressure changes again, it has to be adjusted again. It is really a very troublesome thing to repeatedly adjust the temperature during a shower. For the elderly and children, it is not only a nuisance, but also may cause scald accidents due to lack of sensitivity or improper operation.

In the traditional hot water supply unit system, due to the unbalanced matching between the water consumption of a single tank and the cooling water intake, the difference between the heating speed and the cooling water intake of the tank, etc., the temperature is often hot and cold, and the water supply at the user end is extremely dissatisfied.
