Background technology
At present domestic heat pump water heater or electrical heating hot water machine are typically based on the water temperature of water tank bottom temperature-sensitive bag detection and set
Constant temperature degree relatively to control Unit Commitment, that is, when water tank bottom water temperature opens heat pump less than design temperature certain value, reach
After design temperature, heat pump is shut down.This kind of control mode controlling hot water machine Unit Commitment suffers from the drawback that：
（1）Temperature-sensitive bag quantity is single and position is in water tank bottom, when hot water machine water tank occur low discharge persistently use hot water or
Use a small amount of hot water（Fill into a small amount of cold water）Compressor start up condition will be met, and now water tank middle and upper part or hot water, it is easily caused water
Case middle and upper part water temperature exceedes design temperature, and too high temperature not only can not meet user and require, and also can cause energy dissipation, and
And if hot water machine is chronically at water tank middle and upper part temperature and exceedes design temperature, it will lead to unit operation inclement condition, shorten heat
The service life of water dispenser；Simultaneously as temperature-sensitive bag is arranged on water tank bottom, need the water detecting when controlling hot water machine to shut down
The temperature of lower box part meets and could trigger shutdown during shutdown temperature, so, will result in the full whole box water of needs heating and just can stop
Only heat, also result in energy dissipation.
（2）Can also be met in the case that user uses in the hot water amount of water tank middle and upper part using bottom temperature-sensitive bag and just open
Dynamic heating, this kind of too early start can lead to whole heating process efficiency low, not energy-conservation；And equally also exist whole in heating slow
Shut down in the case of case water, occur shutting down too late and cause energy dissipation.
（3）For circulating unit, with start too early during water can because in start cyclic water tank hot and cold water convection current with mix,
Lead to water tank heat production discharge reduction.
Easily cause the problem of energy dissipation for hot water machine in correlation technique, not yet propose effective solution party at present
Case.

Detection temperature T of unitUnderWhether it is more than or equal to target temperature TIf, judging TUnder≥TIfWhen, control hot water machine to stop heating.?
In mode standard, control the startup of hot water machine by the water temperature in the middle part of water gallbladder, and heat is controlled by the temperature of water gallbladder bottom
The stopping of water dispenser it is ensured that under just conventional regimen condition unit be unlikely to start shooting too early and be also unlikely to shut down too early.
When user issues selection instruction selection energy saver mode, then controlled according to the detection temperature from the first detector unit
Water heating machine open heating, and according to the detection temperature from the 3rd detector unit control hot water machine stop heating it is assumed that
The detection temperature of the first detector unit is TOn（That is, the water temperature on inner water tank top is TOn）, concrete control mode is：Judge first
Detection temperature T of detector unitOnWhether it is less than target temperature TIfWith the difference of default start temperature difference T, judging TOn<TIf-ΔT
When, then control hot water machine to start heating；And in hot water machine heating process, judge detection temperature T of the 3rd detector unitUnderIt is
No more than or equal to target temperature TIf, judging TUnder≥TIfWhen, control hot water machine to stop heating.In energy saver mode, pass through
The startup to control hot water machine for the water temperature on water gallbladder top, and by the temperature of water gallbladder bottom control hot water machine stopping it is ensured that
Start shooting again after in inner bag, hot water is finished water heating, now water tank is all cold water, unit starting water heating energy-conservation, this kind of energy-conservation mould
Formula can be applicable to and meets demand and the situation of follow-up no urgent water demand when one case hot water.
When user issues selection instruction selection half gallbladder energy saver mode, then according to the detection temperature from the first detector unit
To control hot water machine to open heating, and to control hot water machine to stop heating according to the detection temperature from the second detector unit,
Specifically control mode is：Judge detection temperature T of the first detector unitOnWhether it is less than target temperature TIfWith default start temperature difference
The difference of T, is judging TOn<TIfDuring-Δ T, then hot water machine is controlled to start heating；And in hot water machine heating process, judge
Detection temperature T of two detector unitsInWhether it is more than or equal to target temperature TIf, judging TIn≥TIfWhen, control hot water machine to stop
Only heat.In half gallbladder energy saver mode, control the startup of hot water machine by the water temperature on water gallbladder top, and by the middle part of water gallbladder
Controlling the stopping of hot water machine, this pattern is directed to water tank upper half gallbladder and heats temperature, and after guaranteeing that top half gallbladder-heat water is finished
Start shooting again water heating, this half gallbladder energy saver mode can be applicable to and meets demand and follow-up no urgent water demand when half chests hot water
Situation.
Further, default start temperature difference T applied in the control method of the embodiment of the present invention include first preset
Start temperature difference T1, the second default start temperature difference T2, the 3rd default start temperature difference T3, the 4th default start temperature difference T4 and
5th default start temperature difference T5, wherein, the first default start temperature difference T1 is to apply in Fast Modular in embodiments of the present invention
The default start temperature difference in formula, the second default start temperature difference T2 is the default start temperature difference applied in half gallbladder pattern, the 3rd
Default start temperature difference T3 is the default start temperature difference applied in mode standard, and the 4th default start temperature difference T4 is to apply
The default start temperature difference in energy saver mode, the 5th default start temperature difference T5 is the default start applied in half gallbladder energy saver mode
The temperature difference, wherein, the value of each default start temperature difference can identical can also differ it is preferable that setting Δ T1<ΔT2<Δ
T3<ΔT4<Δ T5, i.e. under quick mode, the default start temperature difference can get the small value relatively, starts shooting as early as possible in order to unit；Energy-conservation and
Under half gallbladder energy saver mode, the default start temperature difference can take large values relatively, started shooting with guaranteeing that tank hot water is finished rear unit again, reach
The effect of energy-conservation.
Further, the first detector unit in the embodiment of the present invention, the second detector unit and the 3rd detector unit be also
Multiple temperature temperature-sensitive bags can all be included, in this case then by the inspection to temperature temperature-sensitive bags multiple in certain detector unit
The meansigma methodss of testing temperature carry out calculating the detection temperature to determine this detector unit, i.e. to multiple temperature in the first detector unit
The detection temperature of degree temperature-sensitive bag obtains respectively, and calculates the detection temperature of multiple temperature temperature-sensitive bags in the first detector unit getting
The meansigma methodss of degree, obtain the detection temperature of the first detector unit；Detection temperature to temperature temperature-sensitive bags multiple in the second detector unit
