Description
Technical field
The present invention relates to field of water heaters, in particular to a kind of thermostatic instant heating formula water heater and control method thereof.
Background technology
The water heater that family commonly uses at present has storage-type electric water heater, solar water heater and gas heater etc..
These product technologies are ripe, use comfortable safety.But in use there is problems in that
Using solar water heater and gas heater, due to water heater from outlet water at tail end mouth farther out, centre has one section relatively
Long connecting line, before starting each time to use continuously, the water temperature in connecting line tends not to meet the requirement of user.In order to
Obtaining the hot water of higher temperature, the inner water of this section " connecting line " will be bled off in vain, causes inconvenience and the water resource of use
Waste.
When a large number of users water, when hydraulic pressure reduces, water feeding of heater despite pressure fluctuations, that causes outlet goes out water temperature
Degree fluctuation, causes the uncomfortable sensation of use.
When using storage-type electric water heater, need first the water in storage tank to be heated, if number of users is more, storage tank
The water of middle heating can not meet use demand, needs to wait that the water in storage tank is heated by water heater, otherwise can not reach
Use temperature；If number of users is less, then the hot water in storage tank can slowly turn cold, and wastes the energy；If secondly water stores up for a long time
Exist in storage tank, then easily there is corrosion and cause the aqueous metamorphism in storage tank in storage tank.
In prior art, the control of calandria generally uses one calandria of one group of SCR control, if in use
Controllable silicon breaks down, then water heater quits work, and functional reliability reduces.
Summary of the invention
Present invention aim at providing a kind of can make the water in water heater keep constant simple in construction easy to control
Thermostatic instant heating formula water heater.
For reaching above-mentioned purpose, the present invention proposes a kind of thermostatic instant heating formula water heater, including:
Inner bag, is used for housing a certain amount of heated water；The water inlet pipe being connected with inner bag and outlet pipe, water inlet pipe and
Outlet pipe flows into inner bag for transmitting and flows out the water of inner bag；
The heating unit being arranged in inner bag, described heating unit includes that multiple calandria, the plurality of calandria are compiled successively
Number；
Cladding shell outside the tank, described shell is provided with display screen and operation button, in display screen is used for showing
The temperature of water in gallbladder, operation button is for arranging the working time of water heater, heating-up temperature, being switched on or switched off power supply；
Current detector unit, for detecting the flow of inlet water of the water flowed in inner bag and being sent by the water flow signal of detection
To control unit, described current detector unit is arranged in water inlet pipe；

Giving control unit, described leaving water temperature detector unit is connected with outlet pipe；
Control unit, with calandria, current detector unit, inflow temperature detector unit, leaving water temperature detector unit, operation
Button is connected to control the working time of calandria；Wherein: described controller for according to flow of inlet water, leaving water temperature and
Heating power required for inflow temperature calculating, and send it to switch element；
The switch element being connected with heating unit, switch element controls calandria by controlling the working time of calandria
Work efficiency；
Described control unit has the information recorder of record calandria duty, and when calandria heats, information is remembered
Record the numbering of the calandria of device writing task and to the control unit of sending, when once heating terminates, and calandria needs again
During startup, control unit is according to the corresponding volume after the numbering of the calandria of the numeral order recalls information recorder trace of calandria
Number calandria water is heated.
According to the improvement of the present invention, the present invention also proposes the control method of a kind of thermostatic instant heating formula water heater, including:
Set the leaving water temperature needed；
Detection flows into the flow of inlet water of the water in inner bag；
Detection flows into the temperature of the water of inner bag；
The temperature of the water of inner bag is flowed out in detection；
In response to flow of inlet water, leaving water temperature, the signal of inflow temperature, heating power required for calculating also controls heating
The working time of body, the numbering of the calandria of writing task, if leaving water temperature is equal with the leaving water temperature of setting, then maintain existing
Heated condition is until heating terminates；
The numbering of the calandria of information recorder writing task also to the control unit of sending, when once heating terminates,
When calandria needs to be again started up, control unit is according to the calandria of the numeral order recalls information recorder trace of calandria
Water is heated by the calandria of the corresponding numbering after numbering.
From above technical scheme, the water heater of the present invention is thermostatic instant heating formula water heater, when user needs hot water not
Need to wait the hot water heating in inner bag, saved the time, and inner bag does not has long-term substantial amounts of storage water, inner bag will not have been made
Become corrosion；Current detector unit it is provided with, it is possible to call the calandria of obstructed quantity to water according to discharge in water inlet pipe
Heating, has saved the energy, it is provided that work efficiency；Arrange in the inflow temperature detector unit arranged on water inlet pipe and outlet pipe
Leaving water temperature detector unit, it is possible to adjust the calandria heating of varying number according to inflow temperature and leaving water temperature, and if water inlet
Temperature is less than 10 DEG C, and control unit can send alarm signal, call user's attention protection water heater, it is to avoid water heater damages；When
Leaving water temperature is higher than 75 DEG C, and circuit disconnects, in order to avoid leaving water temperature is too high, scalds user；Temperature protector is for occurring when circuit
During the faults such as short circuit, not accessing water in inner bag, calandria is energized, and when in inner bag, water temperature is more than 105 DEG C, temperature protector cuts off
Operating circuit, prevents dry combustion method from leading to a disaster.
The present invention uses 2 groups of bidirectional triode thyristors to control the work of one group of calandria, when one group of bidirectional triode thyristor punctures, separately
Outer one group of bidirectional triode thyristor can provide work, and only when two groups of bidirectional triode thyristors all can not work, water heater does not works,
Improve reliability and the service life of water heater.
The information recorder of the present invention records the duty of calandria, and after once having heated, water heater opens again
Dynamic, the duty of the calandria that control unit is recorded according to information recorder preferentially calls the calandria not worked, and improves
The working life of calandria.
