Abstract
A kind of water heater warm spot control self learning system, is used for water heater, the water heater includes inflow temperature sensor, leaving water temperature sensors, water flow sensing, main control MCU and storage unit, the water heater warm spot control self learning system include: the current warm spot packet data of acquisition；Whether there is PX to correspond to power P WM dutyfactor value in inquiry storage unit；Detect temperature constant state；It saves and updates warm spot packet data to storage unit；Water heater in use, after water temperature stability, automatically records warm spot data packet and is saved in storage unit, and in this way as the warm spot of water heater controls self study, constant temperature can be more reliable and stable, adaptive currently used environment.
Description
Technical field
The utility model relates to a kind of self learning systems more particularly to a kind of water heater warm spot to control self learning system.
Background technique
Water heater has been obtained universal now, and every household is provided with water heater, however for the hot water of every family
The environment that device uses is different, this results in the leaving water temperature performances of water heater had in different use environments it is many poor
It is different, occur that water temperature is sometimes hot and sometimes cold, and temperature has the phenomenon that larger difference.
Summary of the invention
For the deficiency more than solving, the utility model provides a kind of water heater warm spot control self learning system.
The utility model solves technological system used by its technical problem:
A kind of water heater warm spot control self learning system, is used for water heater, and the water heater includes inflow temperature sensing
Device, leaving water temperature sensors, water flow sensing, main control MCU and storage unit, the water heater warm spot control self learning system packet
It includes: acquiring current warm spot packet data；Whether there is PX to correspond to power P WM dutyfactor value in inquiry storage unit；Detect constant temperature
State；It saves and updates warm spot packet data to storage unit.
The warm spot packet data, including setting temperature and inflow temperature difference T, water flow L and PWM duty cycle
Value.
It is described to inquire after storage unit has PX to correspond to power P WM dutyfactor value, time PWM duty cycle value can be used directly
Operation, direct constant temperature after detecting no fluctuation, then carried out preservation update if once inquiring then using conventional method constant temperature
Storage unit warm spot data packet.
Water heater in use, after water temperature stability, automatically records warm spot data packet and is saved in storage unit, in this way
As the warm spot of water heater controls self study, constant temperature can be more reliable and stable, adaptive currently used environment.
Detailed description of the invention
Fig. 1 is the work flow diagram of the utility model.
Specific embodiment
A kind of water heater warm spot control self learning system, is used for water heater, and the water heater includes inflow temperature sensing
Device, leaving water temperature sensors, water flow sensing, main control MCU and storage unit, the water heater warm spot control self learning system packet
It includes: acquiring current warm spot packet data；Whether there is PX to correspond to power P WM dutyfactor value in inquiry storage unit；Detect constant temperature
State；It saves and updates warm spot packet data to storage unit；
The warm spot packet data, including setting temperature and inflow temperature difference T, water flow L and PWM duty cycle
Value；
It is described to inquire after storage unit has PX to correspond to power P WM dutyfactor value, time PWM duty cycle value can be used directly
Operation, direct constant temperature after detecting no fluctuation, then carried out preservation update if once inquiring then using conventional method constant temperature
Storage unit warm spot data packet.
The warm spot data packet, containing multiple subdata packets, each subdata includes inflow temperature difference data out, water
Data on flows and corresponding power control PWM duty cycle data.
According to specific heat capacity formula: Q=cm △ t, wherein △ t=Q/(cm), c is the specific heat capacity of water, and m is the quality of water, and Q is to inhale
The heat of receipts, and the quality m of water flow L and water is proportional.
It can be obtained according to above formula, the product PX and demand power P of inflow temperature difference △ t and water flow L is at just out
The relationship of ratio.Therefore after water heater temperature is stablized, current warm spot packet information can be recorded by center control MCU, and be mapped to and deposit
Storage unit, when next secondary control, it is only necessary to it is identical corresponding to find out the product of inflow temperature difference data and water flow data
Power control PWM duty cycle data can directly carry out constant temperature power control.
Water heater in use, after water temperature stability, automatically records warm spot data packet and is saved in storage unit, in this way
As the warm spot of water heater controls self study, constant temperature can be more reliable and stable, adaptive currently used environment.
