Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe:
Fig. 1 is the frequency conversion constant temperature electromagnet water heater structural representation of embodiment more preferably of the utility model.
The specific embodiment
As shown in Figure 1, the frequency conversion constant temperature electromagnet water heater of the utility model, it mainly comprises metallic conduit 1, insulating sleeve (figure does not show), electromagnetic induction coil 3, AC power, temperature sense head 4 and frequency-variable controller; The left end of said metallic conduit 1 and right-hand member correspondence respectively are provided with water inlet pipe 11 and outlet pipe 12; Said insulating sleeve is sheathed on the metallic conduit 1, and the mouth of pipe outer at insulating sleeve two ends is provided with baffle plate 2; Said electromagnetic induction coil 3 is set around on the insulating sleeve; Said AC power electrically connects the power end of frequency-variable controller; Said temperature sense head 4 stretches into the inside of said outlet pipe 12 and is electrical connected with the input of frequency-variable controller; The coil lead that draw respectively at the two ends of the output electric connection electromagnetic induction coil 3 of said frequency-variable controller.
Particularly, said insulating sleeve is a porcelain bushing.
Particularly, said metallic conduit 1 is iron straight tube or ferroalloy straight tube.
Particularly, said frequency-variable controller comprises man-machine interface, microprocessor and frequency converter; Said AC power electrically connects the input of frequency converter, and the output of frequency converter electrically connects the coil lead that draw respectively at the two ends of said electromagnetic induction coil 3; Said man-machine interface electrically connects the control end of said microprocessor; The microprocessor input electrically connects said temperature sense head 4, and the output of microprocessor electrically connects the control end of frequency converter.
The AC power of the utility model is mainly used in to electromagnetic induction coil 3 provides its work required alternating current; When alternating current during through electromagnetic induction coil 3; Will produce alternating magnetic fields in metallic conduit 1 inside; Simultaneously alternating magnetic fields can produce eddy current effect by electromagnetic induction again metallic conduit 1 in, thereby utilizes these eddy current effects will be heated into from the cold water that water inlet pipe 11 flows to metallic conduit 1 behind the hot water from outlet pipe 12 outflows.
And in order to realize constant temperature output hot water, and the utility model also is provided with temperature sense head 4 and makes the temperature of hot water keep constant with frequency-variable controller.Wherein, frequency-variable controller is mainly used in the frequency that changes the alternating current that electromagnetic induction coil 3 imported; And temperature sense head 4 is mainly used in the hot water Current Temperatures of gathering and feeding back outlet pipe 12.Temperature sense head 4 feeds back to microprocessor with the hot water Current Temperatures of outlet pipe 12; Microprocessor should current temperature and predefined temperature compare; And result relatively shows through man-machine interface, after the user sees the result of comparison, sends the frequency conversion operating control signal through man-machine interface and gives microprocessor; The frequency conversion operating control signal that microprocessor sends over according to man-machine interface goes to control the work of frequency converter, and is specific as follows:
