A kind of heater protecting equipment provided by the invention comprises control module and fluid sensing unit.Control module by thick film quasi-resistance silk is set, can reset temperature controller and thermistor be separately implemented at the control to heating, and then protection and control heater makes safety, without hidden danger ground work; Under the heater abnormal operating state, by the control of control module, the safety that the protection heater uses.Flow and the temperature of flow cell judgement fluid by controlling the thermal transition amount of heater, are controlled the temperature of heater.
Compare with present technology, provided by the invention for a kind of heater protecting equipment have safety, convenient, energy-conservation multiple heat protective device without potential safety hazard, not fragile heater body is significant.
Description of drawings
Accompanying drawing is used for a further understanding of the present invention, and consists of the part of specification, is used for together with embodiments of the present invention explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is a kind of heater protecting equipment structural representation provided by the invention;
Fig. 2 is a kind of heater protecting equipment electrical block diagram shown in Figure 1.
The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing, it illustrates principle of the present invention as the part of this specification by embodiment, other aspects of the present invention, and feature and advantage thereof will become very clear by this detailed description.
As shown in Fig. 1-2, the invention provides a kind of heater 4 protective devices, comprising: be used for adding the heater 4 of hot fluid, the circuit board 1 of control is set, come disconnected, the logical control module of control circuit by the height of judging temperature, be used for the fluid sensing unit of induction turnover fluid; Wherein, described control module comprises thick film quasi-resistance silk, the temperature controller 3 that can reset, thermistor disconnected 2; Power supply is powered to heater 4, control module and fluid sensing unit by circuit board 1.Described thick film quasi-resistance silk resistance fusing-off temperature is greater than thermistor 2 fusing-off temperatures, and thermistor 2 fusing-off temperatures are greater than temperature controller 3 fusing-off temperatures that can reset.The described temperature controller 3 that resets is arranged on heater 4.The described temperature controller 3 that resets is arranged on the carrier that is provided with on heater 4.The described distance that resets temperature controller 3 and heater 4 is 0-10mm.Be provided with switch on described circuit board 1; After described thermistor disconnected 2 is opened, by switch, thermistor 2 is resumed work.Described thick film quasi-resistance silk silk-screen is on heater 4.Described thermistor 2 and described temperature controller 3 series windings that reset.
As shown in Fig. 1-2, by device thick film quasi-resistance silk, can reset temperature controller 3 and the disconnected 2 three kinds of temperature controllers of thermistor, electric current is controlled, realize the protection to heater 4.Wherein, thick film quasi-resistance silk-screen when heater 4 excess Temperature, by with its fusing, guarantees that it can not catch fire on heater 4, avoids bringing potential safety hazard and damages heater 4, and its fusing-off temperature is the highest; The temperature controller 3 that can reset is arranged on the position apart from heater 40-10mm, can be directly to be arranged on heater 4, also can be arranged on the carrier that heater 4 is provided with, by temperature controller 3 monitoring heater 4 temperature that can reset; When heater 4 temperature during higher than design temperature, 4 outages of 3 pairs of heaters of temperature controller can reset, when heater 4 temperature during lower than set temperature, 4 energisings of 3 pairs of heaters of temperature controller can reset, because the temperature that arranges approaches or only has a temperature very much, so its energising, power-off time very interval are very short, energy-saving effect can be reached, the adjusting of temperature can also be realized; In the time can resetting temperature controller 3 non-normal working, the automatic disconnection when heat that heater 4 sends causes thermistor 2 to reach uniform temperature realizes protection, after thermistor 2 automatic disconnections, needs outage that it is resetted, and just can make device re-start work.By above-mentioned several protection structures, can realize heater 4 spoilage, thereby increase service life of product, reduce the user to the maintenance of machine and save electric energy.
As shown in Fig. 1-2, described fluid sensing unit comprises for the inlet water sensor 5 of controlling flow of inlet water and goes out water sensor 6 for detection of leaving water temperature.Detect and control by the flow that fluid inlet water sensor 5 convection cells are set, detect the fluid temperature (F.T.) of mouth of a river head end by setting out water sensor 6, and then control.
As shown in Fig. 1-2; a kind of heater 4 protective devices provided by the invention comprise by thick film quasi-resistance silk is set, temperature controller 3 can reset; the disconnected 2 three kinds of automatically controlled products of thermistor are separately implemented at the control to heater 4; and then assurance heater 4 trouble free services; when heater 4 under abnormal operating state; control by control module; protection heater 4 and the safety of using thereof; judge flow and the temperature of fluid by flow cell; and then by controlling the thermal transition amount of heater 4, control the temperature of heater 4.By the fluid sensing unit, the flow of convection cell and flow velocity carry out Real-Time Monitoring, and information is returned, and are undertaken heater 4 temperature are controlled by control module.
Compare with present technology, provided by the invention have safety, facilitate the multiple heat protective device of not fragile heater 4 significant for a kind of heater 4 protective devices.
Disclosed above is only preferred embodiment of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to the present patent application the scope of the claims still belongs to the scope that the present invention is contained.
