Definitions
- the present invention relates to the technical field of steam generators for household appliances such as irons, steam cleaners or any other appliance using steam.
- the invention relates more particularly to the regulation and operation of such a generator. It is already known, for example by through document EP-A-0 438 112 to produce an iron with steam connected to a boiler itself connected to a water tank and to a feed pump for said boiler associated with a non-return valve.
- This document describes a steam generator which has a water tank, not pressurized, and therefore accessible at any time during operation or use of the iron.
- the steam generator and in particular the evaporation boiler has means indicating water levels to control the operation of the pump and by consequently the quantity of water brought inside said boiler evaporation.
- the level indicator is for example produced using a thermostat having a thermal transducer extending inside the boiler evaporation to a predetermined level.
- the object of the present invention therefore aims to remedy the drawbacks of the prior art and to produce an evaporation boiler whose supply of water is reliably controlled.
- Another object of the present invention aims to achieve a system of generation of vapor with improved reactivity following a thermal or pressure imbalance, linked to vapor subtraction.
- Another object of the present invention aims to obtain increased reliability of the steam generation system by avoiding the use of water level detectors whose accuracy is influenced by scaling progressive during aging.
- An additional object of the present invention aims to obtain better instant image of the operating status of the steam generator for y bring corrective orders.
- a secondary object of the present invention aims to achieve a steam generator allowing to supply steam by dispensing with significant delays linked to thermal inertia phenomena.
- a steam generator comprising an evaporation boiler associated with heating elements and supplied with water by a pump, a solenoid valve for steam expulsion, as well as regulating means comprising a temperature or pressure sensor to control the amount of water introduced into the boiler and to control the pump, characterized in that the regulation means are associated with an electronic system to perform successive measurements and activate the pump according to a value of slope of a curve representing the change in temperature or pressure, said slope being analyzed by the electronic system.
- the steam generator according to the invention for example shown in Figure 1 is associated with an iron 1.
- the latter is connected to a power supply via a cord 4 and has a button 3 for excitation of a solenoid valve 15, which is used for expelling vapor 2 from the soleplate of the iron 1.
- the steam generator according to the invention comprises a tank 10 containing the water or the fluid intended for evaporation as well as a pump 11 connected to the reservoir 10 via a first pipe 5.
- a second line 6 allows water to be transferred via the pump 1 1 to a boiler 12.
- the second pipe 6 comprises advantageously a non-return valve 7 to prevent the fluid under pressure back into the boiler 12 to flow back to the pump 11.
- the non-return valve 7 can alternatively be integrated into the pump 11.
- the boiler 12 comprises preferably a metal tank 12a which is heated by elements 13. These are fixed on the metal tank 12a by all means and allow to heat said tank to evaporate the water coming from the tank 10.
- the metal tank 12a is in intimate thermal connection with a temperature sensor 14 of the thermistor type 14b.
- This last consists for example of a CTN resistor.
- FIG. 3 shows for this purpose an enlarged view of the temperature 14.
- the thermistor 14b is for example deposited on a substrate ceramic 14a which is bonded to the metal tank 12a. Such bonding can be made with any adhesive resistant to high temperatures and achieving good heat transfer.
- the ceramic substrate 14a is by example consisting of an electrically insulating and heat conducting material of the alumina type, having a thickness of about 0.6 mm. As a variant, a layer of a material whose resistivity varies with temperature, can be deposited directly on the ceramic substrate 14a.
- the substrate 14a is advantageously glued to the outer wall of the metal tank 12a.
- the steam generator according to the invention comprises means regulator for controlling the temperature of the metal tank 12a.
- These regulation means are also associated with an electronic system, which is made for example using a microcontroller 20.
- the latter is electrically connected to the pump 11, to the temperature sensor 14 and to the heating elements 13 via electrical connections 19a, 19b and 19c respectively.
- the means of regulation are used in particular for control the amount of water introduced into the boiler 12 and to control the pump 11.
- the steam generator according to the invention therefore combines these regulation means to the microcontroller 20 for carrying out measurements successive and actuate said pump 11 according to a slope value of a curve representative of the evolution of a physical variable, of temperature or pressure.
- the temperature sensor 14 can be replaced by a pressure sensor connected to the microcontroller 20, possibly through a circuit analog-digital transformation, which is connected to the link electric 19b.
- the metal tank 12a is then provided with a means of thermal regulation and / or a thermal limiter not shown in the figures.
- the heating elements 13 are controlled by the microcontroller 20 and are preferably arranged outside the metal tank 12a of so as to avoid scaling problems on the one hand, and to simplify the assembly process on the other hand.
- the steam generator according to the invention is particularly well suitable for use in an ironing center with a steam iron iron with steam.
- the microcontroller 20 thus makes it possible to process the information from the temperature sensor 14 and order the operation of the pump 11 and the heating elements 13.
- the sensor temperature 14 is preferably mounted on the metal tank 12a in a position close to the bottom of said tank to obtain optimal regulation of the operation of the steam generator according to the invention.
- the steam generator according to the invention operates using a particular regulation process shown diagrammatically in FIGS. 4a to 4d.
- the regulation of the steam generator consists in controlling the pump 11 for supplying water from a determination of the amount of water introduced into the boiler 12 for evaporation and to use information from the temperature 14 or pressure associated with said boiler 12.
- Such a control of pump 11 is improved and supplemented by the process of regulation according to the invention.
- the latter also illustrates the operation of the steam generator according to the invention.
- the abbreviations EV and EC corresponding respectively to the solenoid valve and the heating elements are used.
- the regulation process according to the invention consists in managing the supply of the heating elements 13 by via sensor 14 to obtain temperature regulation around a high TC threshold after a first steam subtraction of the boiler 12. Such a subtraction corresponds to the actuation of the excitation button 3 of the solenoid valve 15.
- the user turns on the heating elements 13 by through the power supply.
- the heating elements stop 13 is commanded after the first lower TA value has been exceeded than the low threshold TB.
- the heating elements 13 are restarted as soon as the temperature drops again below the TA value.
- the heating elements 13 are cycled for obtain thermal regulation around the low threshold TB.
- the generator according to the invention is brought directly to this operating state when the initial temperature of the metal tank 12a is higher or equal to the low threshold TB.
- the method then consists in carrying out successive measurements by through the temperature sensor 14 which aims to calculate a value of slope D of a curve representative of the change in temperature of the boiler 12 and more particularly of the metal tank 12a.
- the actuation of the pump 11 for a period determined as a function of the value of the slope D is thus a step in the process in accordance with the present invention. All stages are preferably controlled by the microcontroller 20.
- the measurements made by the sensor 14 preferably relate to temperatures. However measures relating to pressures may also be suitable without departing from the scope of the present invention.
- the microcontroller 20 does not take account of the openings of the solenoid valve 15, of a duration less than the critical time to, corresponding for example to 1s. Successive temperature measurements or pressure are thus performed when the time t steam exhaust 2 of the boiler 12 exceeds the critical time to.
- Figures 2a and 2b show on the one hand, examples of the durations t of opening of the solenoid valve 15 and on the other hand, the effects on the temperature T of the metal tank 12a. The measurements are preferably triggered 1 second after the opening of the solenoid valve 15.
- the regulation process according to the invention also makes it possible to control the operation of pump 11.
- An example of start-up of the pump 11 is shown diagrammatically in FIG. 4b.
- the process consists, after a actuation of the solenoid valve 15 for a duration greater than to, perform temperature measurements Tl and TF with deviations in time t2 corresponding for example to durations of one second.
- the method then includes comparison steps.
- Slope D is compared to values programmed in the microcontroller 20, to know a first slope D1 corresponding for example to a slope of 4.5 ° C / s and a second slope D2 corresponding for example to a slope of 2.25 ° C / s.
- the microcontroller 20 When the slope D is greater than the value of D1 the microcontroller 20 ignores the measurements. This corresponds to an abnormal operating state.
- the pump 11 When the slope D is between the values D1 and D2, the pump 11 is operated by means of a power supply control said pump 11.
- the microcontroller 20 When, on the other hand, the slope D is less than the value D2, the microcontroller 20 performs a calculation of an average D on several values successive of slope D and compare said mean D to a third slope value D3 corresponding for example to 1.2 ° C / s.
- the average D is greater than D3 the pump 11 is supplied, which allows introduce water into the boiler 12.
- the value mean of the slope D is less than D3 the pump 11 is not supplied.
- the regulatory process according to the invention therefore makes it possible to provide corrective values to the operating parameters of the generator steam by actuating the pump 11 almost instantaneously and even before that the temperature of the metal tank 12a reaches limit values. This is particularly advantageous and innovative in the context of this invention. Regulation is thus ensured dynamically.
- the method according to the invention also comprises steps relating to a command to stop the operation of the pump.
- the pump is turned on. runs and remains in operation for an initial duration t3, corresponding for example to 12s.
- a next step is to compare the temperature T of the tank 12a, at a predetermined TE value. When the temperature is higher than the TE value, corresponding for example to 120 ° C, an additional step is to measure the time operation of the pump 11 since it was started, or time for market. This additional step takes place at most during a additional duration t4, corresponding for example to 20s. If the temperature remains greater than TE when the operating time reaches the duration t3 + t4, the operation of pump 11 is interrupted and an audible signal or visual is sent to the attention of the user. Such a situation corresponds to a tank 10 empty. On the other hand if the temperature drops below TE before the operating time reaches the duration t3 + t4, we proceed simply when the pump 11 stops, without additional signal.
- the process according to the invention can thus be completed using a step consisting in cutting the operation of the pump 11, from a temperature measurement of the boiler 12 and a measurement of the time of operation of said pump 11.
- the stopping of the pump 11 is caused by a succession of steps relating to an analysis of the slope D.
- steps consist in comparing the slope D with a complementary value D4 predetermined.
- the slope D corresponds to the difference between a temperature initial Tl and a final temperature TF, measured at a time interval t5.
- the operation of the pump 11 is interrupted.
- slope D takes a value less than D4
- the pump may stay on as long as the operating time since the last start-up, or on, does not exceed the duration t5 + t6.
- the process according to the invention can thus be completed with a step consisting in cutting the operation of the pump 11, from an analysis slope D and a measurement of the operating time of said pump 11.
- the stopping of the pump 11 is caused by a succession of steps relating to an analysis of the slope D corresponding to the difference between an initial temperature Tl and a final temperature TF measured at a time interval t7. Steps consist in measuring Tl, measuring during time t7 the duration of opening of the solenoid valve 15, measure when the time t7 is reached the final temperature TF, calculate the slope D corresponding to the difference between the temperature initial Tl and final temperature TF, then as a function of slope D and advantageously from the initial temperature T1, stop the pump 11.
- the process according to the invention can thus be completed with a step consisting in cutting the operation of the pump 11, from an analysis the slope D, the initial temperature Tl and a measurement of the time of operation of said pump 11.
- stopping the pump 11 includes a step of calculating a Tx opening rate of the solenoid valve 15 since pump 11 was started.
- the Tx rate corresponds to the ratio the duration of opening of the solenoid valve 15 over the time elapsed since switching on pump 11 on.
- the calculation step of the rate Tx is carried out after the step of calculating the slope D. This step could also be done before calculating the slope D or before the TF temperature measurement. This step can also be considered for the second variant.
- the pump stop condition D ⁇ D4 is then replaced by a condition depending on the slope D and the rate Tx.
- the process according to the invention can thus be completed with a step consisting in cutting the operation of the pump 11, from an analysis of the slope D, of a rate Tx of opening of the solenoid valve 15, possibly of the initial temperature Tl, and a measurement of the operating time of said pump 11.
- This arrangement allows to take into account the quantity of steam used during filling of the boiler.
- the process according to the present invention thus makes it possible to overcome direct control of the water level in the metal tank 12a.
- the microcontroller 20 can be programmed to react only for actuation of the solenoid valve 15 more than a second.
- the process according to the present invention preferably consists to analyze values of slopes of decreasing temperature evolution or pressure.
- a decrease in temperature allows by example of performing slope calculations independently of the feed or cutting the heating means 13.
- the measurements can therefore be performed without taking into account, or without altering the cycling of the elements 13. This considerably simplifies the regulation process according to the invention, and the programming of the microcontroller 20.
- the use a rise in temperature would take into account the power of heating elements 13. Such power is variable from generator to the other and may undergo alterations depending on the power supply of the sector. This would result in a manifest lack of precision as to the measurements performed.
- the values of slopes D can be taken from their absolute or relative values.
- the microcontroller 20 can easily be suitable for either possibility.
- the method according to the invention consists in using a single temperature sensor 14 of the thermistor type 14b. All the implementation work of the regulation process is thus carried out by the thermistor 14b in association with the microcontroller 20.
- Such a simplification of a system of regulation contributes in particular to obtaining reliability and precision optimal.
- the advantage of the regulation method according to the present invention allows said regulation not to be influenced by the power of heating elements or by variations in the power supply of the sector.
- Another advantage of the present invention is obtained by using the use of a single temperature sensor 14 to achieve regulation in temperature and pressure without the use of a pressure switch.
- An additional advantage obtained by the regulation process according to the present invention is linked to obtaining almost instant of an image of the operating state of said generator or the evolution of this state. This allows the regulatory means to provide corrective orders adapted and not influenced by problems scaling or thermal inertia.
- the opening rate Tx of the solenoid valve 15 for managing the stopping of the pump 11 makes it possible to hold account of the amount of steam used during filling of the boiler.
- a steam generator according to the invention can thus provide a wide range of functions by reducing the number of parts and components of said generator.
