Izum se nanaša na napravo za gretje vode ki avtomatsko regulira dovedeno energijo s pomočjo več senzorskega mikroprocesorskega stikala.The invention relates to a water heating device which automatically regulates the energy supplied by means of a multiple sensor microprocessor switch.

Znanih je vec rešitev za reguliranje energije pri napravah za gretje vode. Znane so rešitve nadzorovanja temperature sestavljene iz bimetalnih in digitalnih termometrov, nameščenih na posodi za gretje. Patent UK 7901400 na primer rešuje problem zaščite posode v slučaju da zmanjka vode in tudi regulira energijo s io pomočjo bimetalnega stikala. V US patentu 6,914,514 je autor obdelal posebno vrtso stikala, ki je občutljiv na paro in ki isklopi dovajanje električne energije v grelec pri določeni temperature pare. Patentni spis NL 1024204 uvaja v regulacijski krog še možnost dodathega vklopa energije tudi v primeru, ko je bimetalno stikalo isklopilo dovod energije.There are several known solutions for controlling energy in water heaters. Known temperature control solutions consist of bimetallic and digital thermometers mounted on a heating tank. For example, UK patent 7901400 solves the problem of protecting the container in case of running out of water and also regulates energy by using a bi-metal switch. In U.S. Pat. No. 6,914,514, the author has treated a special steam-sensitive switch that disconnects the supply of electricity to the heater at a given steam temperature. Patent file NL 1024204 also introduces the possibility of additional power-up in the control circuit even if the bimetallic switch has cut off the power supply.

Znane so tudi rešitve nadziranja nivoja moči grelca samega, ki temelje na informacijah temperature grelca ali na predhodno nastavljeni moči. Tak nadzor ni davalj natančen, ker je energija potrebna za gretje vode odvisna od velikosti posode, količine vode sobne temperature kakor tudi od drugih faktorjev. V nadaljevanju velika količina neodvisnih parametrov predstavlja velik problem pri ročnem nadzoru moči. Sama bimetalna stikala so zelo inertna in analiza obstoječih grelcev za vodo kaže, da je poraba energije neprimerno višja od potrebne energije za segrevanje vode. Veliko študij kaže na potrebo boljše regulacije energije, ki bi bila približno v področju teoretične potrebne energije za segrevanje vode potrebnega nivoja. V današnjih znanih rešitvah prihaja do nepotrebnega vrenja, izhaja para, poraba energije je za velik odstotek prevelika in nepotrebna.Also known are solutions for controlling the power level of the heater itself, based on the information of the heater temperature or on the pre-set power. This control is not very precise, since the energy required to heat the water depends on the size of the tank, the amount of water at room temperature and other factors. In the following, a large number of independent parameters represent a major problem with manual power control. The bimetallic switches themselves are very inert and analysis of existing water heaters shows that the energy consumption is much higher than the energy required to heat the water. Many studies point to the need for better regulation of energy, which would be approximately in the area of theoretical energy required to heat the water of the required level. In today's known solutions, unnecessary boiling occurs, steam is generated, energy consumption is by a large percentage too high and unnecessary.

Predmet izuma je naprava za avtomatsko reguliranje energije s pomočjo mikroprocesorskega stikala, ki učinkovito zmanjšuje porabo energije s tem, da automatsko regulira nivo dovedene energije na osnovi izmerjenih parametrov. Naprava za avtomatsko reguliranje energije s pomočjo več senzorskega mikroprocesorskega stikala je sestavljena iz posode za vodo, grelca in več senzorskega mikroprocesorskega stikala. Samo stikalo je opremljeno z senzorjem temperature in senzorjem zvoka.The subject of the invention is a device for automatic control of energy by means of a microprocessor switch, which effectively reduces energy consumption by automatically regulating the level of energy input based on the measured parameters. An automatic energy control device using a multi-sensor microprocessor switch consists of a water tank, a heater and a multiple sensor microprocessor switch. The switch itself is equipped with a temperature sensor and a sound sensor.

S pomočjo akustičnega signala , ki nastaja pri procesu vrenja določi točno točko vrenja. Kombinacija izmerjenih parametrov temperature in zvoka v času je vhodni podatek v mikroprocesor. Najpomembnejša karakteristika več senzorskega stikala je neodvisnost od količine vode, velikosti posode in vrste energije 20 grelca.Using the acoustic signal generated by the fermentation process, determine the exact boiling point. The combination of the measured temperature and sound parameters over time is the input to the microprocessor. The most important characteristic of a multi-sensor switch is its independence from the water quantity, the size of the tank and the type of energy of the 20 heater.

Z algoritmom regulacije energije mikroprocesor določi trenutek isklopa grelca, tako da ne prihaja do nepotrebnega dovajanja energije, ki predstavlja izgubo. Naprava po izumu omogoča tudi predhodno nastavljive in v samem procesu nadzorovane regulacijo po posebnih željah uporabnika.With the power control algorithm, the microprocessor determines the moment of switching off of the heater so that no unnecessary energy supply, which represents a loss, occurs. The device according to the invention also provides pre-adjustable and in the process controlled regulation to the specific wishes of the user.

Naprava za gretje vode ki avtomatsko regulira dovedeno energijo s pomočjo več senzorskega mikroprocesorskega stikala in je samo v eni od možnih oblik prikazana na sliki 01 sestavljajo Ohišje 6 kot rezervar tekočine 3 , ki jo napolni uporabnik do poljubnega nivoja 4. Enerija se dovaja skozi grelec 8, ki je povezan io s podstavkom z priklučnimi kontakti 2. V podstavku so še temperaturni senzor in akustični senzor 1. Naprava ima največkrat še ročaj 7 in pokrov 5. Za regulacijo je vgrajen mikroprocesorsko stikalol.A water heating device which automatically regulates the supply of energy by means of several sensor microprocessor switches and in only one of the possible forms shown in Figure 01 consists of a housing 6 as a reservoir of fluid 3 filled by the user to any level 4. Energy is supplied through the heater 8 , which is connected to the base by means of plug contacts 2. The base also has a temperature sensor and an acoustic sensor 1. The device usually has a handle 7 and a cover 5. A microprocessor switch is installed for regulation.

Na sliki 02 so prikazani mogoči položaji mikroprocesorskega stikala 10, ki je lahko postavljeno v pokrovu, na samem ohišju ali v podstavku.Figure 02 shows the possible positions of the microprocessor switch 10, which can be placed in the cover, on the housing itself or in the base.

Pri procesu segrevanja vode se temperatura vode normalno zvišuje do točke vrelišča vode, ki je približno 100 st. C. pri regulaciji dovedene energije s pomočjo merjenja temperature je sama inercija sistema gretja in višina temperature nedovoljna. Če se želi doseči vrelišče se uporablja druge senzorje za isklop. Največkrat v praksi je to bimetalni senzor, ki direktno isklopi grelec. Na bimetal je usmerjena para, ki nastane pri vretju in z zvišanjem temperatura se v bimetalu ustvari dovolj sile, da preklopi stikalo. Z merjenejem v praksi smo prišli do podatka, da je potreben čas zelo dolg, kar pomeni, da se nepotrebno dovaja energija od začetka vrenja do trenutka, ko se bimetalno stikalo aktivira. Tako porabljena energija vedno presega 15% potrebne energije.During the water heating process, the water temperature normally rises to the boiling point of water, which is approximately 100 cent. C. in regulating the energy input by means of temperature measurement, the inertia of the heating system itself and the height of the temperature are insufficient. Other tripping sensors are used to reach the boiling point. In most cases, this is a bimetallic sensor that switches off the heater directly. Bimetallic is a directional steam generated by boiling, and with increasing temperature, enough force is created in the bimetal to switch the switch. By measuring it in practice, we have come to the conclusion that the time required is very long, which means that energy is unnecessarily supplied from the beginning of the boiling point to the moment when the bimetallic switch is activated. The energy thus consumed always exceeds 15% of the energy required.

V teoriji vrenja je dobro znan diagram inteziteta zvoka v procesu vrenja slika 03. Pri segrevanju se v določenem trenutku pojavi akustični signal, ki nastane zaradi nastanka mehurčkov in na začetku zaradi implozije teh mehurčkov. Vizualno še ne moremo io ugotoviti pojav pare, ko je signal v točki x1. Zaradi toplotne inercije je dovolj energije akumulirano v grelcu in posodi da lahko že v tej točki isklopimo energijo pa bo voda vseeno zavrela brez nepotrebnih izgub.In the theory of fermentation, a well-known diagram of the sound intensity in the fermentation process is shown in Fig. 03. When heated, at some point an acoustic signal occurs, which is caused by the formation of bubbles and initially by the implosion of these bubbles. Visually we cannot determine the appearance of steam when the signal is at x1. Due to thermal inertia, enough energy is accumulated in the heater and the tank so that we can turn off the energy at this point, but the water will still boil without unnecessary loss.

Uporabniki velikokrat želijo še vplivati na način segrevanja 15 vode. Primer je segrevanje vode za kavo , pravi čaj ali kaj drugega določeno na temperaturo. Z vgradnjo izbiralnega gumba 14 na sliki 04 se lahko določi režim v katerem b o deloval grelec. Primer 15 jt ahko automatsko vrenje z optimizirano porabo energije pod 16 položaj Z pa nek drugačen proces kot je segrevanje dojenčkove hrane na 38 st C.Users often want to influence the way 15 water is heated. An example is heating water for coffee, real tea or something else set to temperature. By installing selector button 14 in Fig. 04, the mode in which the heater will operate can be determined. Example 15 is an automatic automatic boiling system with optimized energy consumption below 16 position Z, a process other than heating baby food to 38 ° C.

Osnova hitrega mikroprocesorskega stikala je tiskana ploščica z mikroprocesorjem in potrebnimi elektronskimi elementi na katero so povezani senzorji S1....Sn , izbirni gumb in grelec kot je prikazano na sliki 06.The basis of the high-speed microprocessor switch is a printed circuit board with the microprocessor and the necessary electronic elements to which the sensors S1 .... Sn, the radio button and the heater are connected, as shown in Figure 06.

Za programsko podporo delovanja so primerni algoritmi za regulacijo še posebej pa sistemi z mehko logiko.Regulatory algorithms, especially fuzzy logic systems, are suitable for software support.
