Description

The continuous heaters of electrical adjustment and its driving method
Technical field
The present invention relates to a kind of continuous heaters that is used for adding by calandria the electrical adjustment of hot water, said continuous heaters is controlled by the semiconductor switch that is used for preset power and by the adjuster that is used to regulate power.
Background technology
From DE 4315468C2, obtain a kind of method that is used for driving by the control electronic installation continous way electric heater, said control electronic installation is controlled calandria through power circuit.In addition, be provided with electromechanical switching device, said electromechanical switching device under its open mode with power circuit and network detach and under its closure state, power circuit is applied on the network.The signal that will be used to detect the work of drawing water places on the control electronic installation and when finishing to draw water work, breaks off power circuit and after suspending, opens electromechanics and drive switching device.
Summary of the invention
Based on prior art, the object of the invention based on, a kind of continuous heaters of electrical adjustment is provided, it can work energy-conservationly and wherein reduce the standby loss.In addition, the object of the invention based on, a kind of method that is used to drive this continuous heaters is provided.
According to the present invention, above-mentioned purpose realizes through a kind of continuous heaters.The favourable form of implementation of the present invention provides hereinafter.
To this; Be provided with differential pressure switch, it handles electric switch according to differential pressure, and wherein electric switch is designed to; Connect total heating current and the electric current that is used for adjuster; And adjuster and semiconductor switch are connected on the electric switch, the only power supply under the state of electrical switch closes of said adjuster and said semiconductor switch, and wherein heating current flows through semiconductor switch.
This means that whether the power supply of semiconductor switch and controller is just opened with electric switch or be closed relevant: if switch closure, semiconductor switch is connected with power supply with adjuster so; If switch opens is interrupted the power supply of semiconductor switch and adjuster so.The connection of electric switch is also relevant with differential pressure.Need only water and flow through, then switch closure.On the contrary, when not having water to flow through (water no longer flows through), switch opens.Therefore, only when current out-of-date, promptly when the user draws water on continuous heaters the time, just supply power to semiconductor switch and adjuster.Drawing outside the process switch opens and do not offer semiconductor switch and current regulator.Therefore, adjuster and semiconductor switch do not remain under the holding state drawing outside the process.Therefore, only when drawing water, just set up power supply once more.Reach thus, during stand-by operation, promptly during the time interval that does not need water, reduce the standby loss, because adjuster and semiconductor switch current sinking not at this moment, because it is being connected with power supply.
For this reason, continuous heaters preferably is connected on the electrical network, to be used for power supply.
Preferably, at least one calandria is connected by electrical wiring on the electric switch.At this, calandria preferably only is connected with power supply under the state of electrical switch closes.Thus, further reduce standby loss, because when not drawing water, calandria is current sinking not also.
According to another embodiment, be provided with the temperature sensor of the temperature of effluenting that is used to detect water.Adjuster is connected semiconductor switch, the feasible power of only presetting at least one calandria according to the temperature of effluenting.Reach thus, need not be used for other measured value of the adjusting of power, the volume flow of water for example, making does not need corresponding sensor and assessment unit.
Be used for driving the method for continuous heaters that is used for adding the electrical adjustment of hot water by calandria; Connect the whole power supply of continuous heaters according to the differential pressure of electric switch, wherein said continuous heaters is controlled by the semiconductor switch that is used for preset power and by the adjuster that is used to regulate power.When switch closure, adjuster is connected with power supply with semiconductor switch and adjuster turns on and off semiconductor switch according to the preset rated value of temperature, so that the temperature of effluenting approximately reaches preset rated value.Thus, only when drawing water, semiconductor switch is connected with power supply with adjuster, because mis-tie misclosure compresses switch then, reduces the standby loss thus.Whether the power supply of semiconductor switch and adjuster is just opened with electric switch or be closed relevant: if switch closure, semiconductor switch is connected with power supply with adjuster so; If switch opens is interrupted the power supply of semiconductor switch and adjuster so.The connection of electric switch is relevant with differential pressure again.Need only water and flow through, then switch closure.On the contrary, when not having water to flow through (water no longer flows through), switch opens.Therefore, only when current out-of-date, promptly when the user draws water on continuous heaters the time, just supply power to semiconductor switch and adjuster.Drawing outside the process switch opens and do not offer semiconductor switch and current regulator.Therefore, adjuster and semiconductor switch remain on outside the process under the holding state drawing.Therefore only when drawing water, just set up power supply again.Reach thus, during stand-by operation, promptly do not need therein during the time interval of water, reduce the standby loss, because adjuster and semiconductor switch current sinking not at the moment, because it is being connected with power supply.
In another embodiment, the closure of at least one calandria through switch that is connected on the electric switch is connected with power supply.Thus, further reduce standby loss, because when not drawing water, calandria is current sinking not also.
Another preferred expansion scheme according to the present invention, temperature sensor detects the temperature of effluenting of water.At this, adjuster is only regulated the power of at least one calandria according to the temperature of effluenting, and reaches thus, need not be used for other measured value of the adjusting of power, the volume flow of water for example, and making does not need corresponding sensor and assessment unit.
Description of drawings
