Description
Technical field
The present invention relates to a kind of electric heater, especially one kind to be divided into water storage and the i.e. two-part electric heater of heat.
Background technique
The fast development of social economy causes domestic energy demand constantly to increase, and wherein the energy consumption of pot-type boiler is relatively
It is high.Therefore, energy-saving water heater is of great significance for energy-saving.And it is always encountered in this way in our family lives at present
The problem of:
The principle of heating of storage-type electric water heater is that cold water is directly heated to user's required temperature using principle of electric-heating,
Heat storage water heater has the disadvantage that
1) since water tank volume is big, holding temperature is high, is heated to required temperature and needs the time long；
2) insulating process is needed, since large area exchanges heat, very big thermal loss is had having thermal insulation material, often
Its heat preservation will consume about 2 degree of electricity, the efficiency of the heat storage water heater of 1 grade of energy consumption in the case where keeping the temperature by calculating 24 hours
Only 74.8%；
3) volume is larger, occupies toilet space.
The principle of immediately heating water heater is to make the water of very small part volume can be in the short time using high-power electrically heated rod
Inside reach required temperature, instant water heater has the disadvantage that
1) its power is huge, and up to 8000W or so, and the cable of Chinese New Dwelling toilet generally can only at most connect at present
The electrical appliance for being 5500W or so by power, so having many families only to change circuit could install；
2) hot water is unstable, when water is larger or water temperature is lower heating speed do not catch up with just will appear water it is cool or produce water
Measure few situation.
Summary of the invention
The present invention is to provide for a kind of energy-efficient stagewise electric heater, for solving storage-type electric water heater heat loss
Greatly, low efficiency, the big problem of power consumption and instant electric water heater's power are high, and hot water exports unstable problem.
To achieve the above object, the technical scheme is that a kind of energy-efficient stagewise electric heater, by containment portion
I.e. hot part forms, and electrically heated rod and water storage water temperature sensor are equipped in the water storage liner of the containment portion, described to be
The instant heating inner bag water inlet end of hot part is connected to water storage liner by connecting tube, and the water outlet of instant heating inner bag is connected with leaving water temperature biography
Sensor；The water storage water temperature sensor is electrically connected electrically heated rod by temperature controller；The leaving water temperature sensors pass through temperature
It controls device and is electrically connected instant heating inner bag.
Further, the water storage liner of the containment portion connects inlet valve by water inlet pipe.
Further, i.e. the water outlet of the instant heating inner bag of hot part connects drain valve by outlet pipe.
Further, the instant heating inner bag of the water storage liner of the containment portion and i.e. hot part links into an integrated entity, outside package
Insulating layer.
Further, the power of the electrically heated rod is 2000W.
Further, in use, being first then turned on the water heating and thermal insulation in the water storage liner of containment portion to 30 DEG C
I.e. to containment portion, 30 DEG C of water of heating and thermal insulation carry out secondary speed heat and reach temperature required for user the instant heating inner bag of hot part
Degree.
The beneficial effects of the present invention are:
Energy-efficient stagewise electric heater of the invention passes through pre-set ginseng compared with existing electric heater
Number carries out series of computation, has obtained to draw a conclusion:
The storage water heater of (assuming that water inlet mean temperature is 10 DEG C) level-one energy consumption exports 40 DEG C of hot water of 100L and heat preservation
Total energy consumption for 24 hours is 18708.8kJ, efficiency 74.8%.And the total energy consumption of classification water heater of the invention is 14276kJ, storage
Water section efficiency can achieve 94.7%, and energy conservation 23.7%, as a result considerable.And i.e. hot part power reduces by 3 times,
2000W can be run, and last containment portion 2000W, entire water heater can be run with the power within 4000W, is not required to
Reequip circuit.By cost analysis and calculating, stagewise water heater saves 15% and 17% compared to other two respectively.
To sum up, the present invention has the advantage that
1. highest 4000W does not need repacking circuit；
2. the containment portion completely heated up time of summer 60L liner volume only needs 25 minutes, and common storage-type electric water heater
Want 1.5 hours；
3. i.e. hot part heating time 3 seconds, similar with market, it can be achieved that instant heat；
4. last point is also most important, that is, cost is saved, it is energy saving.

Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
As shown in Figure 1, energy-efficient stagewise electric heater of the invention, is divided into two large divisions: water storage and i.e. hot two parts.
First part is containment portion, similar with storage water heater's principle, by water storage liner 1, insulating layer 7, water inlet pipe 4,
The composition such as connecting tube 3 and electrically heated rod 2.It is equipped with electrically heated rod 2 and water storage water temperature sensor in water storage liner 1, and passes through
Water inlet pipe 4 connects inlet valve.
Second part is that i.e. hot part is similar with instant water heater principle, by instant heating inner bag 5, insulating layer 7, outlet pipe 6 etc.
Composition.5 water inlet end of instant heating inner bag is connected to water storage liner 1 by connecting tube 3, and the water outlet of instant heating inner bag 5 is connected with leaving water temperature
Sensor, and drain valve is connected by outlet pipe 6.
Water storage water temperature sensor in containment portion is electrically connected electrically heated rod 2 by temperature controller.Leaving water temperature sensing
Device is electrically connected instant heating inner bag 5 by temperature controller.
Energy-efficient stagewise electric heater of the invention is the equal of that a water storage heater box is connected with an instant heating inner bag
It forms, outside superscribes one layer of heat preservation material.Water enters water storage liner by water inlet pipe, utilizes 2000W electrically heated rod, energization water supply
Heating, heating and thermal insulation is to 30 DEG C or so, and when using, water enters 2000W instant heating inner bag, by water speed by connecting tube
Heat is discharged to 40 DEG C, then by outlet pipe.
In the case that water heat preservation is generally computed heat preservation in 24 hours at 70 DEG C by traditional storage water heater, level-one energy consumption
The efficiency of water heater there was only 74.8%, and the present invention in containment portion first by water heating and thermal insulation to 30 DEG C, according to heat transfer
It gains knowledge, is reduced with circumstance of temperature difference, heat dissipation capacity becomes smaller, and efficiency will improve, and in the case where being computed heat preservation in 24 hours, efficiency can
Reach 94.7%.Reach an energy-efficient effect.
I.e. the secondary speed heat of water progress of containment portion is reached temperature required for user by hot part.Due to be hot part into
Coolant-temperature gage is 30 DEG C, and compared with instant water heater, inflow temperature is improved, and power can reduce, and is computed about 2000W
It can maintain work.
Energy-efficient stagewise electric heater of the invention makes up two kinds of ingenious combinations of water heater using respective advantage
The deficiency of other side.The thermal loss of heat accumulating portion is reduced using Low Temperature Difference like this, improving is hot part inflow temperature to drop
Low-power, specific use process, such as Fig. 2, shown in 3.
Above embodiment is only clearly stating of making of technical solution of the present invention, working principle, purpose effect, but not office
It is limited to this technical principle, but everything technical principle according to the present invention, any of equal value, modification made belongs to of the invention
Protection scope.
