Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The present invention below will combine accompanying drawing (embodiment) to do further to detail:
With reference to Fig. 1, the present invention includes electric-heating thin film 3, last insulating barrier 2, following insulating barrier 4, thermal insulation layer 5 and heated body etc.; Heated body is a sandwich, is divided into surface layer 1, bottom 6; The upper surface of electric-heating thin film 3 scribbles insulating barrier 2, and lower surface scribbles down insulating barrier 4; Thermal insulation layer 5 is applied to outside insulating barrier 2 or the following insulating barrier 4 and (also can coats thermal insulation layer 5 in the wherein one side of electric-heating thin film 3 earlier, coat insulating barrier 2 then on the two sides of electric-heating thin film 3 again and reach insulating barrier 4 down); The electric-heating thin film 3 that scribbles insulating barrier 2, following insulating barrier 4 and thermal insulation layer 5 is clipped between the surface layer 1 and bottom 6 of heated body, becomes built-in structure.Electric-heating thin film 3 adopts the positive temperature coefficient ptc material to process, and can be used as temperature sensor.Electric-heating thin film 3 can be divided into two sections, and two sections are connected in series during low power run, and two sections are connected in parallel during high power operation.Electric-heating thin film 3 can be made into coiled type, and passes to high-frequency alternating current, when heating liquid, can have magnetization, softening function simultaneously.
The heat efficiency of electric heating wire type's heater is low; Electric-heating thin film type of the present invention is then different, and its heat efficiency is quite high, the reasons are as follows; And be that example is explained with the electric rice cooker: heating wire at first heats a metal derby in the electric rice cooker; Metal derby contacts with pot courage bottom, and the conduction of heat needs through metal derby, because three's contact is not closely; Metal derby itself also loses sizable partial heat energy, and obviously its heat efficiency is very low.The electric-heating thin film type is then different, and it can directly be close to the bottom of a pan (or mail in the pot body, see above-mentioned built-in structure); Moreover, it can also be attached to pot around in addition pot top, form the heating field of a sealing; Improve the heat efficiency effectively, shorten heating time.Based on the electric-heating thin film superior characteristic, this structure is electric-heating thin film to mail in heated body inside, and electric-heating thin film and heated body dissolve and be one.Heated body no longer is a simple metal container in other words, but the container of a padded functional structure.
Any one hot system is not an adiabatic system, all has the problem of " thermal loss ", we can say that " thermal loss " is unique factor of the heat efficiency of this hot system of decision.The law of thermodynamics points out that heat is always transmitted to the low place of temperature from the high place of temperature, forms a temperature gradient, and amount of thermal conduction then is proportional to temperature gradient.Specific to an electric cooking appliance, in the cooker food that need boil, cooker then is outward a space outerpace; When the temperature inside and outside the cooker was identical, the cooker temperature gradient inside or outside was also identical, so electric cooking appliance fries the heat pass to food and to pass to cooker heat outward identical; In other words, useful heat equates with the heat of loss, so the time its heat efficiency just be 50 percent; When the food temperature that is boiled constantly raises; This moment, the cooker temperature gradient inside or outside was also just different, and the outer temperature gradient of cooker is greater than the temperature gradient in the cooker, and therefore the heat of loss is greater than useful heat; This moment, the heat efficiency was lower than 50 percent in other words, and the high more then heat efficiency of food temperature is low more in the cooker! Electric-heating thin film 3 is two-sided, and one side can be described as working face, and another side can be that working face can also be non-working surface by the requirement of heater.If heater is used for electric cooking appliance, another side is exactly a non-working surface, this structural design coat special thermal insulation layer 5 (with reference to figure 1) at non-working surface, make heat only spread out of from working face, this design is called " one-way heat conduction property ".Experiment shows that its cooker outside wall temperature of electric cooking appliance of design is only a little more than room temperature in this way, and this explanation " one-way heat conduction property " heat loss amount is quite few, that is to say that the heat efficiency can be greatly improved.
For the temperature detection problem, be heat sensor to be installed at calandria by conventional way.Because always touch transducer on some points of measured object during thermometric, we can call this method " some contact " method.This structure is to adopt a kind of brand-new thermometry, is referred to as " contactless " thermometry.What need explain here is that the used electric-heating thin film 3 of this structure is a kind of positive temperature coefficient (PTC) materials.Since be ptc material, electric-heating thin film 3 itself is exactly a temperature sensor; Electric-heating thin film 3 is a calandria in this structure, is again a temperature sensor, as long as detect the real time temperature that the real-time resistance value of electric-heating thin film 3 just can obtain electric-heating thin film 3.The real-time resistance value that detects electric-heating thin film 3 is not a very thing of difficulty, and the heater of bigger in fact a little power all need detect the voltage of heater, electric current or electrical power, and this is very conventional design.On this basis, as long as detected voltage just can have been obtained the real-time resistance value of electric-heating thin film 3 divided by electric current, and then just can obtain the real time temperature of electric-heating thin film 3 according to the functional relation of temperature and resistance.Obvious this method is simple more than " some contact method ", and is reliable, accurately.Heating unites two into one with thermometric, is a kind of resource-sharing resource optimization resources conservation notion of innovation.
Yes for the purpose of detected temperatures for the temperature of control heater.But still have very big mistaken ideas on this problem: for the temperature control designer, at first consider temperature control in order to guarantee the heater job security, what secondly consider is temperature control performance, and this is justifiable certainly.But they often ignore a prior problem, Here it is power saving.More greatly then energy consumption is big more to mention temperature gradient when telling about thermodynamic principles above, obviously is energy-conservation requisite means so control temperature subtly.Proposing and implementing a complete energy-saving control method is the thing that this structure urgently will be done.Explain as an example with family's electric heater commonly used below: the used temperature controlling mode of present electric heater is very simple; After the user is provided with the heating-up temperature value; Water heater just is heated to this temperature automatically; And start water heater power supply at any time it is remained on this temperature value, most of users have sufficient hot water in order to guarantee to use water heater, often are transferred to maximum (for example being 80 degrees centigrade) to temperature value; The result be in the water heater one day 24 hours the most of the time all be in the condition of high temperature, waste many energy.The then complete difference of temperature controlling mode that this structure is used; Electric heater only keeps hot water on a lower temperature value, (for example to be 50 degrees centigrade) when idle; When using hot water, in time replenish heat energy, satisfy hot water output and temperature value with this structure distinctive " power doubling method ".Because the water heater most of the time all is on the lower temperature, so the energy of loss also just descends significantly." power doubling method " principle is very simple, for example, is divided into two sections to electric-heating thin film 3, and two sections series connection during low power run with two sections parallel connections, can obtain being four times in the power when connecting during PD during parallel connection.Theoretically; Conventional at present electric hot water also available " power doubling method ", but in fact unworkable, because the heating wire conveyance capacity is poor; Electric current doubles during PD; Can be burnt very soon, thereby cause serious security incident, then there is not this problem (with reference to the argumentation of preamble heating wire and electric-heating thin film difference) in electric-heating thin film.
This structure also has the resource-sharing resource optimization resources conservation function of a uniqueness, and Here it is can magnetize softening function simultaneously to liquid when heating liquid.
As you know, can produce incrustation scale when adding hot water, incrustation scale is very big to boiler operatiopn harm, needs at any time water to be softened processing.The liquid material of some chemical enterprise (like the sugarcane juice in sugar refinery), the situation of its fouling is more serious.Eliminating fouling has chemical method that physical method is also arranged, some material such as drinking water, and sugarcane juices etc. can only be used physical method.More effective physical method commonly used is magnetization.The magnetizer function is single at present, and this structure is compound, is heating magnetization simultaneously again.Concrete design is that electric-heating thin film 3 is processed coiled type, and passes to high-frequency alternating current, and high-frequency alternating current can heating liquid can form high frequency magnetic field again and cause the liquid magnetization.This thermomagnetization complex function that adds of this structure can be guided out a series of new products.Believe that the application of magnetized drinking water is very extensive as you know: a lot of diseases can prevented and eliminate to drinking magnetized water, but take a shower with the magnetized drinking water beauty treatment, and it is dirty or the like that tableware, clothing can kill the mattress easy decontamination of sterilizing with magnetized drinking water.So can design novel water dispenser, electric heater, washing machine, dishwasher, hot-water boiler, steam boiler or the like with magnetizing function with this structure.Can expect that the heater that this structure designed can replace present institute's having heaters, can also carry out secondary development, produce more better energy-conserving and environment-protective green products, its market prospects are quite wide.The more important thing is that this structure has important breakthrough aspect energy-conservation, this is the good job that promotes the well-being of mankind.
