Description

 The invention relates to electronic household appliances with electronic control and a thermoelectric heating element and can be used in electric irons with steam humidification and spraying water for ironing fabrics and products from them.

A steam iron is known, comprising a casing, a casing with a water tank, a sole with a thermal heater and an evaporation chamber, into which water enters through a supply pipe and dropper. The evaporation chamber is closed by a lid, the edge of which is docked and fixed on the surface of the sole having a protrusion, the lid covering the upper surface of the evaporation chamber and the section with steam outlet openings in the sole. Along the entire periphery of the outer edge of the casing on the sole, a protrusion is made hermetically adjacent to the sole, and the cover is pressed against the sole by another protrusion, and the pressed portion on the edge of the sole and the portion on the outside of the cover are coated with silicone sealant [1]
The disadvantages of the known device are:
the complexity of the assembly process associated with sealing the camera with silicone material and requiring carefulness to prevent liquid silicone from entering the camera, not precluding such contact, and the connected parts must have high manufacturing accuracy, which complicates the manufacture;
water is not excluded from the steam holes in the sole due to insufficient separation by the labyrinth along the length and height of the chamber from the steam outlet;
sealing is not provided at the junction of the steam valve-dropper and the bottom of the water tank, since the steam valve is mounted on the iron body, and the water tank on the casing.

Known electric iron with a device for automatically turning off the power and temperature control, containing a tactile sensor to indicate the working and non-working state of the electric iron, a signal converter from a tactile sensor, a comparator, a time relay, a multivibrator, an audio signaling device, a transistor, the base of which is connected to the output of a time relay, and a collector to the control electrode of the triac. The anistor of the triac is connected to the L power bus, and the cathode is connected through a bimetallic temperature regulator to a heating element, the second output of which through a fuse is connected to the N-bus power. The signal from the tactile sensor is formed as a signal between a metal electrode inserted into the handle of the electric iron and the neutral (case E-bus) on the capacitance formed by the user's hand relative to the neutral [2]
When releasing the handle of the electric iron, the potential at the inverting input of the comparator changes due to a change in the capacitive divider formed by the capacitor at the input of the comparator and the capacity of the user's hand. The comparator switches to the high voltage mode at the output and turns on the time relay, the output signal of which triggers the multivibrator controlling the sound signaling device and turns on the transistor, which closes the triac, and no current flows to the heating element. The device uses a thermo-bimetallic temperature controller that operates independently of the signal device.

The disadvantages of the known device are:
the connection of the power supply of the heating element with the user's hand through a tactile sensor, which forces the user to compare the pauses between the working movements with the time of the time relay and constantly hold the iron to heat it;
one delay time interval does not provide a combination of fire safety and ease of use. With a short delay (30-40 s), the electric iron on the rear support will constantly turn off and must be held in your hand. With a long delay (5 minutes, as described in the patent), an iron left unattended on the sole will cause the fabric to ignite;
the device uses a thermo-bimetallic temperature controller, which cannot provide the necessary accuracy of maintaining the temperature of the sole and the quality of ironing;
a device with a tactile sensor can be used only with a three-wire power supply network having a grounded neutral, which makes the use of such a device for a household two-wire network impossible.

 Known electric iron with a safety switch and temperature indicator according to US patent N 4692589, class. H 05 B 1/02 (published September 8, 1087), containing a sole with a main heating element and a steam chamber, a manually reset switch, a steam distribution pump with a tube immersed in a water tank, a steam regulator with a steam valve, a temperature regulator with a thermo-bimetallic temperature sensor and a mechanical temperature setter, a device for automatically disconnecting the circuit of the main heating element with a fixed iron.

 The device for automatically switching off the heating element has a temperature sensor, a potentiometric temperature controller that changes its position simultaneously with a mechanical temperature controller that controls the thermo-bimetallic temperature controller. The device also contains a comparator, the output of which is connected to the first input of the LED indicator, a time relay circuit containing a mercury switch for the position of the electric iron and connected to a pulse generation circuit, the outputs of which are connected to the indicator and the thermostatic switch circuit, which consists of a triac, heating resistor and contacts switching off the main heating element with a return button connected in series with a thermobimetallic temperature controller.

 The heating element of the electric iron is connected in series with the thermo-bimetallic temperature controller and the contacts of the thermostatic switch, the presence of current in this circuit is signaled by a yellow LED.

 The set temperature is set by adjusting the thermo-bimetallic controller; at the same time, the potential at the input of the comparator is set. The comparator turns on the green indicator LED when the temperature is within the set limits. The temperature regulator autonomously connects the heating element and power supply, providing a predetermined temperature.

 The mercury switch, depending on the horizontal or vertical position of the electric iron, changes the time constant of the time relay, which, when the iron is stationary, after a specified time forms the output signal for starting the pulse generator.

 The pulse generator includes a red LED, the blinking of which signals the immobility of the iron, and also includes a control circuit for the thermostatic switch. Current pulses heat the heating resistor of the thermostatic switch, which after some time opens the circuit of the main heating element. By pressing the return button on the thermostatic switch, the heating element is again connected to the power supply.

The disadvantages of the known device are:
the presence of a thermostatic switch containing a heating resistor that does not disconnect from the network when the main heating element of the electric iron is disconnected;
the difficulty of adjusting the shutdown time of a stationary electric iron, which consists of the time constant of the time relay and the thermal time constant of the thermostatic switch, for which mechanical adjustments must be provided;
the presence of two temperature sensors, one sensor is actually a thermo-bimetallic temperature controller, the second sensor is a thermistor for a temperature indication circuit. There must be a balance between the sensors so that the temperature controller and the temperature indicator, working independently of the controller, show the same process;
the impossibility of using an electronic controller due to the incompatibility of the temperature control method with a sequential mechanical temperature controller with an electronic stationary iron signaling device, including an electromechanical thermostatic switch;
inefficient LED circuit for signaling the stationary state of the iron in the form of a flashing red LED, which cannot attract the attention of the user if it is not aimed at working with an electric iron;
the need for constant translation of the electric iron into a vertical position, since the contacts of the mercury position sensor are closed and the time relay is switched to a time constant of 8 minutes only in the vertical position of the electric iron;
the presence of a mechanical button to return the thermostatic switch to the on position of the heating element reduces the reliability of the device, and the presence of mechanically switched contacts in the power circuit of the heating element leads to their burning and arcing between them, which further reduces the reliability of the device.

The closest technical solution, the prototype is an electric iron with a device for thermal control and alarm stationary state of the electric iron [3]
The electric iron comprises a housing, a sole with a heating element, and a one-story steam chamber having many labyrinth channels along the entire plane of the sole with an evaporation chamber in the center of the sole. The steam chamber is closed by a plate-lid, in which a steam valve-injector is mounted, connected by a pipeline to a bellows pump, which injects a portion of water into the steam chamber when the steam control button is pressed. The steam valve is also connected by another pipeline through a mechanical regulator for supplying water to the steam chamber with a water tank. The second bellows pump is connected to the water tank by a suction pipe, and the output pipe with a water spray and is controlled by a second button.

 The electric iron has a neon lamp for turning on the power and two LEDs for signaling temperature operating modes controlled by an electronic temperature controller, and a device for signaling the stationary state of the electric iron, which disconnects the heating element from the power supply after a certain immobility time of the iron in the horizontal and vertical plane.

 The electronic temperature controller and the device for signaling the stationary state of the electric iron contain a stabilized voltage divider, a temperature sensor and a temperature setter, forming a bridge circuit with a stabilized voltage divider, the measuring diagonal of which is connected to the comparison comparator and channel comparator, a channel comparator, the output of which is connected to a green LED, and a comparison comparator and the measured temperature, the output of which through a chain of resistors is connected to the control electrode t an aristor, a time relay controlled by a mercury motion and position sensor, a time relay comparator whose output is connected to a red LED and a stabilized voltage divider, a charging transistor with a pulse differentiator of a mercury sensor at the input, an electromechanical relay whose contacts are connected in series with the heating element, and a winding included in the anode circuit of the thyristor, a half-wave rectifier, a parametric stabilizer of the secondary power source, an RC filter.

 Comparison of the set and measured temperature is performed on a comparator, the output of which is connected through a chain of terminating resistors to the thyristor control electrode, the anode of which is connected to the secondary DC voltage source through the winding of the electromechanical relay, obtained by rectifying and parametrically stabilizing the alternating voltage of the alternating current power supply network. The power supply through the contacts of the electromechanical relay feeds the heating element of the electric iron.

 At a temperature of the sole that is lower than the set value, the comparison comparator includes a thyristor, the anode current of which includes an electromechanical relay, the contacts of which connect the heating element to the power supply.

 When the temperature reaches the set value, the comparator turns off the thyristor, the contacts of the electromechanical relay open and disconnect the heating element from the power supply.

At the same time, a channel comparator operating in the zone of ± 30 ^о С of the equilibrium point of the set and measured temperature includes a green LED, which indicates that the temperature of the electric iron is within the set limits.

 When the electric iron is stationary in a horizontal position on the sole, the mercury sensor closes its contacts, and the capacitor of the time relay discharges through its contacts, after 30 seconds the time relay comparator is turned on, the output signal of which illuminates the red LED and simultaneously shorts the two resistances of the stabilized voltage divider so that the comparison comparator disconnects the thyristor and through it the heating element from the power supply.

 When the electric iron is stationary in the vertical position, the contacts of the mercury sensor are open, the capacitor of the time relay discharges through a large resistance in 8 minutes, and the comparator of the time relay disconnects the heating element from the power supply in the same way as the horizontal position.

 When the electric iron moves, the sensor contacts are closed and opened by a drop of mercury, these pulses are converted by a pulse differentiator and a charging transistor to the charge pulses of the time relay capacitor, and the comparator of the time relay does not turn on, the red LED does not light. A neon lamp signals the inclusion of a power plug in the network.

The known prototype device has the following disadvantages:
the significant complexity and unreliability of the design of devices that supply water to the steam chamber and the nozzle of the sprayer due to the large number of pipelines whose joints must be sealed;
the presence of a camera placed at the same level on a large area of the sole, which with a large amount of water leads to incomplete vaporization and sharp changes in the temperature of the sole;
low manufacturability of the assembly, associated with the need to connect small pipes with pipelines, sealing the connection points of the steam valve and the cover of the camera;
insufficient thermal insulation of the casing and the handle, in which the electronic devices are placed, from the sole, as the metal layer directly contacts the body and transfers heat to the sole, and this layer covers only part of the body. This leads to an increased temperature in the pen and destabilizes the operation of electronics, as well as creates discomfort to the user;
turning on and off the heating element is made by the contacts of the electromechanical relay. The presence in the device of a high-current relay with current through the contacts (5-10) A significantly reduces the operational reliability of the device and shortens the life of the electric iron. So, during normal operation of the thermostat for 1 h, the relay operates 30-50 times, while the guaranteed number of relay operations is limited by the number of 10.000 operations. Thus, 10,000 (30-50) = (330-200) hours of relay operation are guaranteed. In a modern iron, the service life should be at least 1500 hours.

In addition, with frequent opening of the contacts with current (5-10) A, the contacts burn out, their resistance increases, the likelihood of their welding increases, which increases the fire hazard of the circuit;
the presence of a mercury motion sensor and position, to which special requirements are imposed in terms of tightness in order to maintain safety of use, however, maintaining absolute tightness is impossible;
the inefficiency of signaling the stationary state of the electric iron is manifested in the fact that the signal about the immobility (red LED flashing) appears after the time relay is activated, i.e. after the maximum specified time of a stationary state, and at the same time the heating element is turned off. Thus, the illumination of the red LED does not signal the presence of a fire hazardous stationary state of the electric iron, but the disconnection of the heating element from the power supply, i.e. to eliminate this dangerous condition. In addition, this type of alarm has a lack of information and is passive;
low accuracy of regulating the temperature of the electric iron in operating mode, due to the fact that the bridge circuit, which includes a sensor and a temperature setter, also contains resistors used for signaling. A significant number of resistors increases the instability of the potentials of the circuit at the input of the comparator and complicates its adjustment. In addition, the output of the comparator time relay is connected in parallel with part of the resistors of the bridge circuit. Such inclusion leads to an additional error in balancing the bridge circuit due to the influence of the collector current of the closed time relay comparator on the potential distribution of the bridge circuit. This error consists of the temperature component of the change in the collector current of the output transistor, the comparator and the time component of the change in the collector current of the comparator during the aging of the comparator elements during operation.

This component of the current increases the error in measuring and maintaining the temperature during operation, i.e. changes the calibration of the temperature setter;
the presence of a pump in the water supply system to the chamber creates inconvenience to the user due to the need to assess the presence of steam from the sole holes and, if there is no need to manually supply a new portion of water to the chamber with a pump;
the presence of three mechanical governing bodies (a sprinkler pump button, a steam capacity regulator on the side wall of the body, and a water supply button to the steam chamber) complicates the work with an electric iron;
the possibility of water leaving the holes in the sole due to insufficient separation of the steam distributor from the camera;
insufficient operational durability associated with the appearance of scale in steam generating parts, which cannot be removed without completely disassembling the iron.

 The present invention solves the problem of improving operational consumer properties, improving reliability, fire safety and manufacturability of the manufacture of electric iron.

The technical result achieved by the proposed electric iron is:
a general increase in consumer properties of electric iron due to:
a) improving the accuracy of maintaining the temperature of the sole with an electronic temperature controller that controls the on and off of the heating element, regardless of the alarm and shutdown device;
b) ensuring fire safety and comfort by means of an active form of signaling the stationary state of an electric iron, followed by turning off the heating element;
c) lowering the temperature in the area of the body, the back cavity, the casing and the handle due to the metal screen between the body and the sole, which in turn increases the reliability of electronic components, improves manufacturability due to the possibility of using less heat-resistant plastics having better molding and decorative properties, and reduces the cost of manufacturing;
d) improving the controllability of the operation of the electric iron by combining in one control button the functions of supplying water to the nozzle of the sprayer and adjusting the steam output;
e) automating the supply of water to the chamber with the installed capacity, automatic signaling and turning off the heating element after a safety time, automatic switching and transfer of the functions of thermal control or signaling of a stationary state, depending on the nature of the movement of the electric iron;
in increasing the intensity of vaporization due to the serial connection of two steam chambers located in the closest proximity to the heating element and having labyrinth channels of considerable length and cross-section, which contribute to the effective conversion of water and steam-water mixture into high-temperature steam;
the ability to control the steam flow from zero (dry ironing) to a maximum value due to the screw pair in the steam valve with automatic water supply to the steam chamber;
in the exclusion of the ingress of water into the outlet for the distribution of steam due to the protrusion in the diaphragm, which does not allow water to slide into the second chamber and due to the presence of extended labyrinths in both cameras;
the ability to clean the steam chambers from scale during operation due to the possibility of simple assembly and disassembly of the elements of the steam chambers connected by one screw, which greatly simplifies and extends the operation of electric irons in hard water and increases its maintainability;
to increase the reliability of operation of the electric iron due to multi-pass channels in both steam chambers, as a result of which frequent deposits of scale do not affect the operability and productivity of the steam chamber;
to simplify the control of water supply and steam generation through the use of a single button, the press of which controls spraying, and the rotation, made independently of pressing, controls the amount of automatically supplied water to the camera;
to increase the accuracy of temperature control due to the isolation of the temperature control circuit from the alarm elements of the stationary state of the electric iron and connecting the output of the temperature regulator to the second input of the triac control unit through a key element;
to increase fire safety due to the preliminary generation of a warning signal about the stationary state of the electric iron with the subsequent shutdown of the heating element with the accuracy of forming the time intervals of shutdown and maintaining the stability of the device parameters during long-term operation;
in improving the consumer properties of the electric iron (comfort, ease of use, stability of parameters) also due to the active form of signaling in the form of intermittent sound signals that persist throughout the connection of the electric iron to the power network;
in increasing reliability and durability due to the exclusion of contact elements in the high-current executive circuit and the use of a triac included in the triac control unit.

 The diaphragm protrusion faces the first chamber and is connected through holes in the gasket and in the metal plate with a blind hole in the sole with a gap in diameter and an end that communicates along the ring of the gap with the exit of the first chamber. The through hole of the protrusion of the diaphragm communicates with the beginning of the multi-way labyrinth of the second chamber, formed by the vertical edges of the lid, the ends of which are pressed against the diaphragm without a gap.

the first chamber is made in the recess of the sole and is formed by vertical edges of the sole of the same height, forming an extended maze for steam;
the beginning of the labyrinth through the channel in the sole through the sealing sleeve in the housing is connected to the outlet of the steam valve;
a metal plate forming the bottom of the first chamber and pressed against the ends of the ribs of the first chamber by the diaphragm through an extension gasket;
a cover, the vertical ribs of which form the labyrinth of the second camera and are pressed against the diaphragm with a screw;
the protrusion in the diaphragm, facing the first camera, passes through the gasket and the metal plate into a blind hole in the sole with a gap along its diameter and end;
the gap ring between the diaphragm protrusion and the blind hole communicates with the output of the first camera;
a through hole in the protrusion of the diaphragm, communicating with the beginning of the second camera;
the output of the second camera from the opposite side communicates with the steam distributor;
the location of the steam distributor along the outer contour of the lid between its outer vertical rib and the outer edge of the second steam chamber;
holes made in the side surface of the outer edge of the lid for steam removal, mating with grooves in the sole, which, when the electric iron is on the fabric, form extended channels for steam to exit;
the labyrinths of both cameras are multi-pass;
placing the motion sensor and position with electronic devices on the board in the cavity of the rear support, which is removable and connected to the casing with one screw;
Installing the steam valve tightly in the bottom of the water tank;
connecting the steam valve stem to the steam valve with a screw pair, wherein the steam valve stem ends with a conical needle that mates with a conical hole in the steam valve;
a sealing sleeve with an opening tightly connecting the outlet of the steam valve to the inlet of the first camera;
a concave metal screen mounted on the shoulder of the insulating sleeves with a gap between the screen and the sole and between the screen and the body;
the connection of the motion sensor and the position through the sensor signal converter with the first input of the alarm and shutdown device containing a series-connected reference voltage source, a timing device, a comparator unit and a key block, the second outputs of the reference voltage source are connected to the second inputs of the comparators block, the second inputs of the timing device and the key block and the third input of the comparator block are connected to the first input of the alarm and shutdown device, and the outputs of the key block are connected with an audible warning device and the first input of the triac control unit;
connection of the second input of the triac control unit through a key element with the output of the electronic temperature controller;
the connection of the output of the zero-organ with the first input of the key element;
the presence of a circular groove on the stem of the steam valve with a sealing ring outside the body of the water supply mechanism.

The electric iron has two controls:
a temperature dial to set the desired temperature for heating the sole;
water control button allowing:
a) when repeating, adjust the amount of water entering the steam chamber (steam production);
b) when double pressed and released, actuate the pump that supplies water to the nozzle of the sprayer.

The electric iron has automatic modes:
regulating the temperature of the sole with an electronic temperature controller;
sound alarm when stationary in a horizontal or vertical plane after a certain time of immobility;
turning off the heating element while maintaining a stationary state after the sound signal appears after a certain fire safety time;
disabling the audible alarm when resuming operation (movement) with an electric iron;
turning on the heating element when resuming work with an electric iron;
water supply to the chamber in the range from zero (dry ironing) to the maximum value;
shutting down the heating element and circuit elements with a thermal switch when the soleplate overheats above a predetermined temperature of the thermal switch without self-resetting.

 The electric iron has manual modes of water spraying by double-clicking on the water control button and a mode for setting various feathering intensities by turning the control button from zero to the maximum value due to the smooth change in the opening of the steam valve.

 When the control button is pressed, the pump rod moves down, the pump inlet is closed with a ball, and water is pushed out through the nozzle. When the control button is released, the compression spring lifts the pump rod up to its original position, a vacuum is created in the pump cavity, and water flows through the water supply pipe into the pump cavity. Spraying water by pressing the control button and adjusting the intensity of steam generation by turning the control button are carried out independently due to the free connection of the steam valve needle to the steam valve stem with a square splined connection.

 Water from the water tank with the steam valve open, drops through the sealing sleeve and the through hole in the sole onto the metal plate that forms the bottom of the first steam chamber, is sprayed, converted into steam. Steam and steam-water mixture along the maze of the first steam chamber move towards the hotter section of the sole to the exit of the steam chamber. The output of the first camera is connected to the input of the second camera through the through hole of the protrusion of the diaphragm, which enters the blind hole of the sole above the first camera. This eliminates the ingress of water into the second chamber. Steam and the rest of the steam-water mixture enter the beginning of the second steam chamber located under the first through the through hole in the protrusion of the diaphragm. The steam enters the hottest spot of the second chamber between the two diverging branches of the heating element and moves to the steam distributor, which is located along the outer contour of the lid, i.e. closest to the heating element, which eliminates the drop in steam temperature and the formation of condensate. The presence of two series-connected cameras located one above the other and located in the hottest place of the sole in the immediate vicinity of the heating element ensures the complete conversion of water into steam and allows increasing the intensity of vaporization. The location of the labyrinth of the first and second steam chambers so that water and steam, moving from the beginning of the labyrinth to the end in each steam chamber, move to more heated sections of the steam chambers, improves the process of vaporization and allows you to increase the rate of vaporization by converting more water coming from steam adjustable steam valve.

 The labyrinths of the steam chambers are multi-pass, which significantly increases the reliability of the electric iron and maintains the intensity of vaporization when using hard water, since the channels of the steam chambers retain their throughput for a long time.

 The presence of a prefabricated design of both steam chambers connected by a screw that is screwed into the sleeve in the sole allows cleaning the labyrinth of the steam chambers, which significantly increases the maintainability of the electric iron and extends its life.

 The location of the steam distributor along the outer contour of the cover in close proximity to the heating element, i.e. in the hottest place of the sole, it allows high-temperature steam to enter the steam outlet without drops of water, which improves the quality of ironing.

 The pairing of the outlet side openings for the exit of steam from the steam distributor with the grooves in the sole, which are their continuation, with the entry of high-temperature steam into them, provides high quality ironing due to the large humidification zone through the elongated grooves in the sole.

 Serial connection of the heating element with an electronic switch triac, which is controlled by the triac control unit, allows you to improve the quality of the on / off control of the heating element with the highest efficiency and reliability by eliminating contact elements.

The connection of the triac control unit through the key element with the output of the electronic temperature controller, and with the output of the alarm and shutdown device provides automatic shutdown of the heating element:
when the set temperature is reached through the thermal feedback of the sole of the electric iron with the temperature sensor of the electronic thermostat;
when the electric iron is stationary in a horizontal or vertical position, which is determined by a motion and position sensor connected via a signal converter of the sensor to the input of the alarm and shutdown device.

 The alarm and shutdown device, based on the signals of the motion sensor and the position, generates a signal to turn on the audible alarm and a control signal to turn off the heating element after a certain time.

 The alarm and shutdown device consists of a reference voltage source, a timing device, a comparator unit, and a key unit.

 The reference voltage source generates stabilized exact values of the setpoint voltages for the timing device and the comparator unit and is connected to their inputs. The timing unit generates a ramp voltage, which is compared in the comparator unit with the set voltage. Each setting characterizes a given time for the sound signal or the shutdown signal of the heating element. An increase in the accuracy of the formation of these signals is ensured by the use of a stabilized source of reference voltages, the formation of the output voltage by an active integrator, and comparison of the voltages at the input of electronic comparators.

 In the presence of electric iron movement, signals are received from the motion and position sensor, which set the time-setting device to its initial state.

 The comparators of the comparator unit generate signals of the corresponding state of the electric iron and, through the block of keys, turn on the buzzer and the control unit of the triac after a time determined by the comparator of the comparator unit.

 At a temperature below a predetermined temperature, the electronic thermostat generates a key element enable signal that transmits pulses from the output of the zero-organ to the input of the triac control unit, which turns on the triac through the control electrode. The heating element is connected to a power source, heats up and heats the sole of the electric iron. After reaching the set temperature, a zero signal appears at the output of the electronic thermostat, and the triac turns off the power to the heating element, the temperature of the sole goes down, and the electronic controller switches the heating element back on as described above.

 In series with the heating element, a thermal switch is connected, which has good thermal connection with the sole of the electric iron. When the soleplate overheats above the permissible temperature, for example, if the electronic thermostat malfunctions, the thermal switch opens the power circuit of the heating element, ensuring fire safety of the electric iron.

 The presence of an annular groove on the stem of the steam valve with a sealing ring allows you to increase the amount of water poured into the tank by sealing the connection of the stem of the steam valve to the body of the water supply mechanism.

 The installation of a metal concave screen on the heat-insulating sleeves with a gap from the sole and from the sole-shaped body provides heat reflection to the side of the sole and reduces the temperature of the body, casing and cavity of the back support, which improves the performance of the electric iron and increases the reliability of electronic devices, as well as allows the use of less heat-resistant plastics for housing and casing.

In the particular case of performing the electric iron according to claim 2 of the claims, the technical result is:
in increasing the sensitivity of the device to acceleration in the horizontal plane due to the free movement of the ball on a smooth concave base without obstructing elements (depressions, contacts, etc.);
in expanding the functionality, which consists in setting the necessary value of sensitivity to acceleration by changing the mass of the ball;
obtaining axially-symmetric characteristics of the device for acceleration in the horizontal plane due to the symmetric concave segmented surface of the bottom of the closed cavity, which ensures the use of the device for reciprocating movements in any direction in the horizontal plane, in particular, for electric iron when ironed with lateral movements;
to simplify the design of the device due to the absence in the sensor of electrical contacts and mechanical parts requiring balancing;
to increase the reliability and durability of the device due to the new design of the motion sensor and position with a contactless conversion device that does not contain contact and spring elements.

 The technological result of the proposed electric iron in the particular case of performing according to claim 2 of the claims is achieved by the fact that the motion and position sensor has a housing with a lid forming an internal closed cavity having a concave segmented bottom with a hole in the bottom of the bottom in which the light emitter of the converter is installed sensor signals of the radiating surface towards the inner cavity, at the bottom of which a translucent gasket is installed, on which the light-tight ball is freely located, having a diameter larger than the diameter of the hole in the housing, a hole is made in the sensor cover that is aligned with the hole in the sensor housing, in which a photodetector of the sensor signal converter is installed.

 In a stationary horizontal position, the ball occupies the lower point of the bottom of the housing on the light guide gasket and blocks the light flux from the light emitter to the photodetector. The sensor signal converter generates a low potential at the output.

 In a stationary vertical position, the ball stops on the lateral surface of a closed cavity, and a high potential is formed at the output of the converter.

 The potential (low or high) from the output of the sensor signal converter ensures the operation of the time-setting device in the integration mode.

 If there is acceleration in the horizontal plane in any direction, the ball moves from the bottom of the bottom and opens the way for the light flux. Since the surface of the light guide strip is smooth, has no holes or contact elements interfering with the movement of the ball, the ball does not sink into the hole, and therefore the sensor has a high sensitivity to acceleration of the reciprocating motion.

 Since the ball in the proposed sensor is not associated with the need to manufacture it from metal, the sensitivity to acceleration can be significantly increased and can vary widely between the choice of the material of the ball and the change in its mass.

 During reciprocating movements in any direction in the horizontal plane, the ball rolls relative to the bottom center, intersecting the light flux of the light emitter, and potential transition pulses from a high level to a low level and vice versa are formed at the converter output.

 Each pulse returns the output voltage of the timing device to its initial state, and the voltage at its output does not reach the voltage of comparison of the first and second comparators.

 The absence in the motion sensor and position and in the signal converter of the sensor of contact and spring mechanical elements simplifies the design, increases the reliability and durability of the device.

The technical result of the proposed electric iron in the particular case of execution according to claim 3 of the claims is:
in increasing the efficiency of sound signals due to their intermittent nature to better attract the attention of the user.

 The technical result of the proposed electric iron in the particular case of execution according to claim 3 of the claims is achieved by the fact that the sound signal device comprises serially connected strobe pulses generator, sound frequency generator and sound emitter.

 The strobe generator generates low-frequency pulses of the meander type, half of the period of which (at a resolution of zero potential) is included in the operation of the sound frequency generator, which ensures the formation of intermittent sound signals.

In the particular case of performing electric iron according to claim 4 of the claims, the technical result consists in:
to increase the accuracy of temperature control due to the isolation of the bridge thermal control circuit from the elements of the alarm signal of the stationary state of the electric iron and the inclusion of a comparator controlling the key element at the output of the bridge circuit;
in simplifying the thermoregulation scheme due to the use of a simple bridge circuit at the input of the comparator, the thermistor and the resistor of the temperature setter are included in the opposite arms of which.

 The technical result of the proposed electric iron in the particular case of execution according to claim 4 of the claims is achieved by the fact that the electronic temperature controller contains a bridge circuit with a temperature setpoint and a thermistor, the measuring diagonal of which is connected to the comparator inputs, the power diagonal is connected to a DC power source, between the output of the comparator and a resistor is included in its non-inverting input, and the thermistor has a thermal connection with the sole of the electric rod.

 The bridge circuit included at the input of the comparator and containing only the temperature sensor and setpoint and balancing resistors of the circuit accurately determines the excess of the actual temperature over the set temperature and generates an output signal that controls the key element that disconnects the connection between the zero-organ output and the input of the simistor control unit.

 Increased regulation accuracy is obtained by decoupling the bridge circuit from the signal elements of the stationary state of the electric iron and the absence of stray currents that upset the balance of the bridge circuit or alter the potentials of the comparator inputs, as is the case in the prototype.

In the particular case of performing the electric iron according to claim 5 of the claims, the technical result achieved by the invention is:
to improve the manufacturability and manufacture of electric iron and increase the coefficient of assembly due to the finished reservoir design in the form of a separate unit and the subsequent assembly of the electric iron without the use of a tool;
to increase operational convenience due to the ability to pour and pour water into the tank separately, without danger, pour hot iron or burn it when pouring water during ironing;
in increasing the capacity of the tank due to the volumetric form, covering the casing with a handle on both sides;
the ability to use an electric iron for dry ironing with a removed tank, which makes it possible to iron hard-to-reach spots;
the ability to quickly switch from dry ironing to steam and humidification and vice versa.

 The technical result of the proposed electric iron in the particular case of execution according to claim 5 of the claims is achieved by the fact that the water tank is removable and has U-shaped side protrusions extending beyond the vertical plane of removal parallel to the plane of the housing between the housing and the housing with a handle and tightly covering the housing with the inner part, the upper part of the tank body has a protrusion fixed to the stop in the handle of the electric iron with a spring-loaded latch, the bottom of the water tank around the protrusion of the steam valve has a cylindrical second annular bead connected without play with a cylindrical recess of the housing.

 The water tank is made in the form of covering the Central part of the casing, is located between the lower part of the handle and the housing and can be removed from the electric iron to fill it with water. The U-shape of the tank allows you to easily and stably install it on the plane of the casing in the coverage of the lower part of the casing (under the handle), while the cylindrical annular flange of the bottom of the tank is fixed inside the cylindrical recess of the casing, giving the tank stability on the casing and eliminating the possibility of its longitudinal and transverse movement . To fix the reservoir on its body, a protrusion is made, which freely enters the groove on the end of the handle facing the reservoir, and is fixed in it against the stop by a spring-loaded latch, which is manually pushed back.

 To remove the tank from the electric iron, the latch is pushed towards the rear support, the latch comes out of the stop between the upper part of the groove and the protrusion, freeing it from fixing. Raising the reservoir, raise the annular bead above the annular recess and moving the reservoir, freed from fixation, towards the nose of the electric iron, remove it from the electric iron.

 The ease of removal and installation of the tank, the possibility of filling it with water and draining the water without an iron creates convenience for the user during operation, and also allows the use of electric iron with dry ironing with a removed tank, which creates additional comfort when ironing in hard-to-reach places.

 The water tank 5 contains (see FIGS. 1, 15, 16) the actual tank 5 with a water supply mechanism 6 (shown in FIG. 1), a vertical plane for removing the tank 74, a protrusion on the tank body 75, a cylindrical annular shoulder 78, the bottom 13 , with a steam valve 7 mounted in it, a water supply mechanism 6 with a control button 41, side protrusions of the tank 80.

 The housing 1 is designed to connect the soles 2, the casing with the handle 4, and thermal insulation of the casing with the nodes in it from the hot sole. The housing can be made of heat-resistant plastic by injection molding.

 The sole 2 is designed for ironing fabrics and products made of them, has an internal cavity in the recess in the sole 23 from the side of the ironing surface, in which the first camera 8 and a blind hole 22 are made.

 In the sole 2, a heating element 3 of a U-shape is installed by pouring or caulking.

 The sole 2 has a through channel 14 for water inlet into the steam chamber 8, which is hermetically connected to the outlet 16 of the steam valve 7 using the sealing sleeve 15.

 In the sole 2, during its manufacture by casting, a sleeve 63 is reinforced with a threaded hole into which a screw 64 is screwed when the cover 27 is installed.

 The heating element 3 is designed to heat the mass of the sole 2, is located in the sole 2 symmetrically relative to the longitudinal axis of the electric iron and covers the cameras 8, 9, which are located inside the U-shaped heating element 3.

 The heating element 3 is connected to an alternating current network 61 through a thermal switch 62 and a triac 60 (see figure 5).

 The casing with a handle 4 is designed to install a temperature setter 66 with a disk 67, a temperature alarm lamp 72, as well as to protect the water supply mechanism 6 and give the electric iron its shape.

 The casing 4 is connected to the housing 1 by screws.

 The water tank 5 is designed to fill it through the hole 38 with water, which through the side openings in the steam valve 7, the open steam valve and through the outlet channel 16 is fed into the chamber 8, and through the water supply tube 69 into the pump cavity 43.

 The water tank is installed on the housing 1, sealed with a sleeve 15 and secured by a casing 4 to the housing 1.

 A mechanism for supplying water 6 is hermetically mounted on the water tank 5, for example, by means of screws, ears with holes on the mechanism body 6 and blind threaded holes on the body of the tank 5 (not shown).

 In the particular case of execution according to claim 5 of the claims, the water tank 5 is removable (see Fig. 15) and contains a vertical removal plane 74, a protrusion of the tank body 75 for securing the tank in the handle, a cylindrical annular collar 78, fixing the tank on the housing 1 using its cylindrical recess 79, the lateral protrusions of the tank 80, covering the inner part of the lower part of the casing and stably fixing the tank on an electric iron.

 The ability to remove the water tank provides significant ease of use when filling and draining water and improves the manufacturability of electric iron assembly by the ability to use the node-by-assembly assembly method, which reduces the overall assembly time of the electric iron.

 The water supply mechanism 6 is designed to supply water to the steam chamber when working with steam or to supply water to the sprayer using the control button 41.

 The water supply mechanism 6 has a control button 41 connected to the stem of the steam valve 42, for example, by pressing on the end of the stem having a longitudinal notch. The rod 42 is placed in a cylindrical groove of the body of the mechanism 6 with free sliding and the possibility of rotation and is spring-loaded by a compression spring 45. At the end of the rod 42, a square groove is made in which the needle of the valve 39 with a cone is freely placed. A rod 43 of the pump 43 is rigidly connected to the stem 42 in the longitudinal direction, for example, by means of a bracket fixed to the end of the stem 43 and freely entering the groove on the stem of the steam valve so that when the control button 41 is rotated, the stem 42 freely rotates in the connecting bracket, and the pump stem 42 does not change its position. When the button 41 is pressed, both rods 42, 43 move downward, overcoming the elastic force of the spring 45, while the needle of the steam valve 39, while remaining stationary, enters the slot of the stem of the steam valve 42. The pump rod 43 ends with a cuff that can move without a gap in the cylindrical case of the mechanism 6, at the bottom of which a ball 46 is freely located, closing the exit from the tube 69 when the pump rod 43 moves down and opening it when the rod 43 moves up due to the resulting vacuum in the housing. The stem of the steam valve 42 has a cylindrical groove in which the sealing ring 44 is inserted. The ring 44 is pressed against the body of the mechanism 6 from below by a spring 45, which provides sealing of the water tank 5 at the junction of the stem of the steam valve 42 and allows to increase the volume of water to be filled into the tank 5.

 The needle of the steam valve 39 by means of a screw pair 40 is mated to the steam valve 7 and provides a variable diameter of the outlet of the steam valve 7. The water supply is adjusted by turning the control button 41, the rotation is transmitted through the rod 42 to the needle of the steam valve 39 through a movable connection with the inner square. The rod 42, rotating on the thread of the pair 40, raises the needle with the cone 39, and the hole for the passage of water in the steam valve 7 increases.

 When you press the control button 41, the stem of the steam valve 42 freely slides along a square connection with the needle of the steam valve 39, and the water supply to the steam chamber 8 does not change. Simultaneously with the control button, the pump rod 43 moves, pushing water through the nozzle. When the button 41 is released, the spring 45 moves the pump rod 43 upward and sucks the water into the pump through the water supply tube 69, while the ball valve 46 releases the inlet opening under the influence of the current of water.

 The steam valve 7 is designed to control the amount of water entering through the outlet of the steam valve 16 into the through channel 14 and through it to the first steam chamber 8.

 The steam valve 7 is installed hermetically in the bottom 13 of the water tank 5, for example, by reinforcing when casting the plastic bottom 13 of the water tank 5 and protrudes above the bottom surface to seal the connection of the steam valve 7 with the sole 2 using the sealing sleeve 15. The steam valve 7 has several radial openings for the flow of water from the water tank 5 through an open steam valve into the outlet 16.

 The amount of water entering the outlet 16 of the steam valve 7 is adjusted using a screw pair 40, which, when the steam valve 42 is rotated, raises the needle with the cone 39 upward, increasing the size of the outlet of the steam valve 7.

 The first chamber 8 is formed in the indentation 23 of the sole 2 with vertical ribs 11 forming a labyrinth 12 with the beginning of the labyrinth at the outlet of the through channel 14 and the end of the labyrinth at the outlet 25 of the first chamber 8. The bottom of the chamber 8 is formed by a metal plate 17 pressed against the ends of the vertical ribs 11 through the gasket 18, the diaphragm 19 and the cover 27 with a screw 41.

 The first steam chamber 8 is designed to convert water droplets falling on a metal plate 17 from the through hole 14 at the beginning of the maze into steam and a finely dispersed steam-water mixture, which move through the maze 12 under pressure towards the outlet 25 of the steam chamber 8.

 The second camera 9 is located under the first camera 8 and is formed by vertical ribs 28 of the cover 27, forming a labyrinth with the beginning of the labyrinth 26 and the end of the labyrinth at the exit 30 of the second camera 9. The beginning of the labyrinth 26 is located under the through hole 21 in the protrusion 20 of the diaphragm 19. The upper part of the camera 9 formed by a diaphragm 19, which is tightly pressed to the ends 29 of the ribs of the cover 27, the second steam chamber 9 is designed to completely transform the steam-water mixture into steam, which under pressure moves through the outlet channel 30 to the steam distributor 31.

 The first camera 8 communicates with the second camera 9 through the diameter gap between the protrusion of the diaphragm 20 and the inner diameter of the blind hole 22 and through the gap at the end between the ends of the protrusion 20 and the hole 22, through the through hole 21, the end of which is located above the labyrinth 26 of the second camera 9 .

 A metal screen 10 (see Fig. 13) is mounted on the flange of the heat-insulating sleeves 24, which fit tightly into the blind holes in the sole 2, in an amount of at least three. On the other hand, the bushings 24 fit tightly into the recess on the protrusion of the housing 1. The screen 10 is pressed against the collar of the bushings 24 by the protrusion of the housing 1 and is fixed with screws (at least 3). The screen is designed to reflect thermal radiation from the sole 2 towards the body 1 and the casing 4 and significantly reduces the temperature of the casing, as well as the casing with a handle 4 and the cavity of the rear support 70 with electronic devices, which facilitates the operating conditions of electronic elements and increases their reliability, as well as facilitates the operating conditions of all devices of the electric iron and improves the comfort of its use. Thermal insulating sleeves 24 can be made, for example, of ceramic, and the screen of duralumin.

 The sealing sleeve 15 is installed in a cylindrical groove in the sole 2, passes through the holes in the screen 10 and in the housing 1 and after installing and fixing the water tank 5 with the steam valve 7 covers the outer cone of the protruding part of the steam valve 7 and seals the connection of the output of the steam valve, blocking the leakage of water into the space between the sole 2 and the body 1 and the space between the body 1 and the reservoir 5. The sleeve 15 has an inner hole for connecting the opening of the steam valve 16 with the through channel 14 for the flow of water.

 The sealing sleeve 15 may be made of plastic rubber by baking.

 The metal plate 17 forms the bottom of the first steam chamber and is tightly pressed to the ends of the ribs 11 of the first steam chamber 8. The plate 17 is made of metal with good thermal conductivity. Water drops drops from the through channel 14 onto the hot plate 17, is crushed, partially turning into steam, and enters the maze of the first steam chamber.

 The metal plate 17 together with the gasket 18 ensure the tightness of the first steam chamber 8 and allow descaling of the steam chamber after their removal.

 The sealing gasket 18 is installed between the diaphragm 19 and the plate 17 and is designed to seal the first steam chamber 8, which ensures the passage of steam throughout the labyrinth 12 of the steam chamber 8 from the beginning to the exit 25. The sealing gasket 18 can be made of elastic material that provides overlapping of the slots along the contour.

 The diaphragm 19 is installed between the ribs of the cover 27 and the gasket 18 and forms the upper part of the second camera 9. The diaphragm 19 has a protrusion 20 in the form of a sleeve with a through hole 21 for connecting the output 25 of the first camera 8 with the second camera 9. The outer surface of the protrusion 20 is free with a gap at the end and in diameter it enters the blind hole 22 in the sole 2, and the upper part of the diaphragm plane overlaps the blind hole 22 so that the vapor from the first camera 8 can enter the second camera 9 only through the hole 21 in the protrusion 20. The aperture 19 may be formed of a heat conductive alloy such as duralumin, or molded entirely press-fitting the protrusion 20 in the aperture plate 19.

 The lid 27 with vertical ribs 28 forms a second chamber 9. The ends 29 of the ribs 28 are pressed against the diaphragm by a screw 64 wrapped in a sleeve 63. The beginning of the labyrinth 26 of the second chamber is located under the through hole 21 of the protrusion 20 of the diaphragm 19. The steam and the rest of the steam-water mixture under pressure from the first chamber served in the labyrinth of the second steam chamber and from its exit 30 to the steam distributor 31. In the second steam chamber, the remaining steam-water mixture is converted into steam. Cover 27 may be molded from the same material as sole 2.

 The steam distributor 31 in the lid 27 is an external groove along the contour of the lid 27 formed by its ribs 32 and 33 and is designed to evenly distribute the steam into the outlet vents 35 for venting steam, which mate with the grooves 36 in the sole, which form closed when the electric iron is positioned on the fabric longitudinal channels for steam exit.

 Board 47 is designed to install a motion sensor and position 48 and electronic units 49.60 (see figure 5) and is mounted on racks 73 installed on the casing 4, with screws.

 The motion and position sensor 48 is designed to determine the status of the electric iron and the formation of the light signal of a fixed horizontal or vertical position of the electric iron and the presence of its movement and is connected to the input of the signal transducer of the sensor 49.

 The motion sensor and position 48 in the particular case of execution according to claim 2 of the claims may be performed as shown in Fig.6.

 The sensor 48 has a housing 48.1 with a cavity having a segmented concave bottom 48.2. At the bottom of the bottom 48.2, a hole 48.3 is made in which a light emitter 49.1 of the converter 49 is installed, for example, a light emitting diode of the type Al341, radiating part towards a closed volume 48.5.

 The housing 48.1 is closed by a lid 48.4 having an internal cavity, which together with the internal cavity of the housing 48.1 forms a closed cavity 48.5, designed to freely accommodate the ball 48.7.

 The ball 48.7 has a diameter larger than the diameter of the hole 48.3 in the housing for blocking the light flux of the light emitter 49.1.

 The cover 48.4 has an opening 48.6, coaxial with the opening 48.3, into which a photodetector 49.2 of the transducer 49 is mounted, for receiving light radiation from the light emitter 49.1 and converting it into an electrical signal.

 In the horizontal stationary position of the sensor 48, the ball 48.7 occupies a lower position on the light guide gasket 48.8 corresponding to the center line of the hole 48.3, blocking the luminous flux from the light emitter 49.1 to the photodetector 49.2.

 In the vertical stationary position of the sensor 48, the ball 48.7 rolls onto the side surface 48.9 of the closed cavity 48.5, and the light flux from the light emitter 49.1 is incident on the photodetector 49.2. During the reciprocating movement of the electric iron, and with it the sensor 48 in any horizontal direction, the ball rolls around the equilibrium position, crossing the light flux of the light emitter 49.1.

 The housing 48.1 and the cover 48.4 of the sensor 48 can be made of metal or plastic and have an external shape, both in the form of a cylinder, or any other.

 At the bottom 48.2 of the housing 48.1 installed translucent gasket 48.8, made, for example, from a molded polymer film. Gasket 48.8 covers hole 48.3 and provides a smooth, even bottom surface for ball 48.7 without a depression in the center of the bottom. This embodiment of the bottom increases the sensitivity of the sensor to acceleration, since the ball has no obstacles to move either in the form of recesses on the bottom or in the form of an opposing spring, as is the case in known devices using a ball (see, for example, German patent N 3702361 30.07.87, CL H 05 B 1/02 "Safety device for automatically disconnecting the power supply of mobile devices, in particular for an iron").

 The signal converter of the sensor 49 is designed to convert the light flux from the light emitter 49.1, controlled by a ball 48.7 into electrical signals at the output.

 The signal Converter of the sensor 49 can be performed as follows. The light emitter 49.1 is made in the form of an LED with a direct current resistor. Photodetector 49.2 is made of a phototransistor, for example, FT-1K type with a load resistor in the collector circuit, a forming inverter is connected to the collector of phototransistor 49.2, the output of which is the output of device 49. When the electric iron is stationary, when the ball 48.7 is at the bottom of the bottom on the gasket 48.8 and blocks the luminous flux of the light emitter 49.1, the photodetector 49.2 does not receive light, its resistance is high, and a zero signal is generated at the output of the converter 49.

 With a stationary vertical position of the electric iron, when the ball 48.7 is on the lateral surface of the closed cavity 48.5, the light emitter 49.1 illuminates the photodetector 49.2, its output resistance is small, and a single signal is generated at the output of the converter 49 through the output inverter in the converter 49.

 The motion and position sensor 48 is mounted on the board 47, for example, by soldering the sensor leads into the board caps and is electrically connected through a converter 49 to the input of the alarm and shutdown device 50.

 The alarm and shutdown device 50 is designed to generate warning sound signals after a predetermined time after stopping and maintaining the stationary state of the electric iron in the horizontal plane (on the sole) and in the vertical plane (on the rear support) and generating a shutdown signal for the heating element after a certain predetermined stationary state time.

 The device 50 is connected at the input to the motion sensor and position 48 through the signal converter of the sensor 49 and at the output with an audible warning device 55 and a control unit of the triac 58.

 The alarm and shutdown device 50 comprises a reference voltage source 51, a timing device 52, a comparator unit 53, a key unit 54, and may be configured as shown in FIG. 7.

 The comparator unit consists of four comparators 53.1.53.4, the first inputs of which are connected to the output of the timing device 52, the second inputs to the second outputs of the reference voltage source. The third inputs of blocking the comparison operation of comparators 53.1, 53.2 are connected to the first input of the device 50. The outputs of the first and third comparators are connected to the first inputs of the first key element 54.1, and the outputs of the second and fourth comparators with the first inputs of the second key element 54.2.

 Comparators 54.1.54.4 compare the output voltage of the timing device 52 with various installation voltages at the outputs of the source 51 and generate signals characterizing the time the electric iron was in a stationary horizontal (53.1, 53.2) or vertical (53.3, 53.4) state.

 The reference voltage source 51 is designed to generate a highly stable DC voltage for the measuring circuit of the integrator of the timing device 52 and is connected to its first input and to generate stabilized reference voltages at the second inputs of the comparator units 53, with which the output voltage of the integrator of the device 52 is sequentially compared.

 The reference voltage source 1 can be performed, for example, according to the scheme of Fig. 8.

 The source 51 has an AC voltage stabilizer on the capacitor 51.1 and zener diode 51.2, a rectifier 51.3, a capacitive filter 51.4, an input divider on resistors 51.5, 51.6 and a smoothing capacitor 51.7, an operational amplifier 51.8 for decoupling the output voltage.

 The output of amplifier 51.8 is connected to series-connected resistors 51.9, 51.10 and resistors 51.11.51.15, from which the reference voltages supplied to the second inputs of the comparator unit 53 (outputs 2.5) and the voltage to input 1 of the timing device 52 (output 1) are removed.

 The timing device 52 is designed to generate a linearly varying voltage, the magnitude of which is proportional to time, and is connected to the first inputs of the comparator unit 53 and to the output of the reference voltage source 51.

 Time-setting device 2 can be performed, for example, according to the circuit of FIG. 9 based on a linear integrator on an operational amplifier 52.2 with a large time constant determined by the capacitor 52.9. In integration mode, the amplifier 52.2 operates with the key transistor 52.8 closed. With the transistor 52.8 open and saturated, the amplifier 52.2 operates in the mode of an inverting operational amplifier with a unity gain. Transistor 52.8 is closed when zero or one potential is applied to input 2, i.e. when the motion and position sensor 48 is in a horizontal or vertical stationary position, i.e. the potential at input 2 is not passed through the isolation capacitor 52.7.

Then the voltage at the output of the amplifier 52.2 varies from the initial value U _beg. downward relative to the common tire U _l according to a linear law. The pulses at input 2, which are received at input 2 when the electric iron is moving, are differentiated by the RC circuit 52.7, 52.4 and turn on the transistor 52.8, restoring the initial voltage U _beginning at the output of the integrator (amplifier output 52.2). At the input 1 of the device 52, a stabilized constant voltage is supplied from the reference voltage source 51, which, through the resistor 52.1, creates an integrable potential difference at the input of the operational amplifier 52.2. Differentiating capacitor 52.7, diode 52.6 and resistors 52.3.52.5 are used to turn on the transistor 52.2.

The comparator unit 53 is designed for sequentially comparing the linearly varying output voltage of the timing device 52 with the setpoint voltages from the output 2 of the reference voltage source 51 and consists of four comparators 53.1.53.4 (see Fig. 7), the second inputs of which are connected to the outputs 2 ₁ .2 ₄ sources of reference voltages 51. The third inputs of the comparators 53.1, 53.2 are connected to the input 1 of the device 50, i.e. with the output of the motion sensor and position 48 (via the transducer 49) and are the inputs for blocking the comparison of voltages on the comparators 53.1 and 53.2 with a single signal from the output of the transducer of the signals of the sensor 49, since in the vertical stationary state of the electric iron, the output voltage of the device 52 should be compared with the set voltage at the inputs of the comparators 53.3 and 53.4.

 The inputs 3 of the lock of the comparators 53.1, 53.2 can be performed, for example, by connecting a direct-connected diode with an inverting input of an operational amplifier connected to the first input of the comparator. Then, when a single signal arrives from the converter 49 (vertical position of the electric iron), the comparators 53.1, 53.2 are blocked for comparing the signals at the first and second inputs, and a zero signal is set at their output.

 Comparators 53.1. 53.4 are intended for sequential comparison of the output voltage of the timing device 52 as it changes with the setpoint voltages and generating equal signals of the output voltage of the integrator of block 52 to the setpoint setpoint. Since the signal at the output of the comparators 53.1.53.4 appears after a certain integration time, this signal forms a predetermined time interval of the sound signal and the shutdown signal of the heating element.

 So, comparator 53.1 is triggered, for example, after 30 s, comparator 53.2 after 60 s, comparator 53.3 after 5 minutes, comparator 53.4 after 8 minutes.

 A time of 30 s and 5 min determines, respectively, a predetermined time of a stationary state of the electric iron in horizontal and vertical positions, and a time of 60 s and 8 min turn off the heating element 3 in these immobility states.

 The outputs of the comparators 53.1, 53.3 are connected to the first inputs of the key element 54.1, and the outputs of the comparators 53.2, 53.4 with the first inputs of the key element 54.2, the second inputs of the key elements 54.1, 54.2 are connected to the output of the sensor signal transducer 49.

 The key element 54.1 is designed to switch the signals of the comparators 53.1 and 53.3 to the buzzer 55 and is connected to its input.

 The key element 54.2 is designed to switch the signals of the comparators 53.2 and 53.4 to the first input of the control unit of the triac 58. The key elements 54.1 and 54.2 are switched depending on the output signal level of the signal converter 49 of the motion sensor and position 48.

 At a zero signal level of the sensor 48, the inputs of the elements 54.1 and 54.2 are connected to the comparators 53.1 and 53.3, respectively, which characterizes the horizontal stationary state of the electric iron.

 At a single signal level of the sensor 48 (vertical position of the electric iron), the inputs of the elements 54.1 and 54.2 are connected respectively to the comparators 53.2 and 53.4.

 Key elements 54.1 and 54.2 can be performed on relays or electronic transistor switches.

 The sound signaling device 55 is intended for generating intermittent sound signals when a signal appears at its input from the comparator 53.1 with the horizontal position of the electric iron after 30 seconds of a stationary state or from the comparator 53.3 with the vertical position of the electric iron after 5 minutes of stationary state.

 The acoustic signaling device 55 can be performed, for example, according to the scheme of FIG. 10 based on two self-excited low-frequency generators connected in series. The first generator 55.1, consisting of elements 55.4.55.8, generates periodic pulses of low frequency, gating the operation of the second generator 55.2 sound frequency. The second generator, consisting of elements 55.9. 55.12, loaded on a sound emitter 55.3, generating intermittent sound signals during gating periods of the first generator of strobe pulses.

 The electronic temperature controller 56 is designed to maintain a predetermined temperature in the center of the sole of the electric iron and is connected through a key element 57 to the second input of the control unit of the triac 58. The electronic temperature controller can be performed according to the scheme of Fig. 11.

 The temperature sensor 65 is included in one shoulder of the bridge circuit and is designed to measure the actual temperature of the sole of the electric iron and is a thermistor.

 The temperature controller 66 is included in the second arm of the bridge circuit and is a potentiometer, the engine of which sets a potential proportional to the set temperature of the sole at the input of the differential amplifier.

 The bridge circuit, in one arm of which a temperature sensor 65 is connected, in the other a temperature controller 66, in the third and fourth arms are balancing resistors 56.2, 56.3, is designed for accurate measurement and transmission of the measured temperature signal to the input of the comparator 56.5 regardless of fluctuations in the supply voltage.

 The measuring output of the bridge circuit is connected to the input of the comparator 56.5, designed for threshold amplification of the voltage difference at the measuring output of the bridge circuit and controlling the key element 57.

 Resistors 56.2, 56.3 form the second shoulder of the bridge circuit and determine the initial equilibrium potential of the bridge circuit, resistor 56.1 is an additional resistance to the master 66. Resistor 56.4 determines the response zone of the comparator.

 The key element 57 is connected by a second input to the output of the null-organ 59, and by an output with the second input of the control unit of the triac 58 and is designed to connect pulses from the output of the null-organ 59 to the input of the control unit of the triac 58 when the sole temperature of the electric iron is lower than the set when the comparator 56.5 includes key element 57.

The control unit of the triac 58 is designed for:
turning on the triac 60 at a soleplate temperature of the electric iron below a predetermined temperature set using the temperature setter 66;
turning off the triac 60 at the sole temperature of the electric iron above a predetermined one;
turn off the triac 60 when the horizontal or vertical position of the electric iron is stationary when a single signal arrives at input 1 of block 58;
ensuring the operation of the temperature controller upon receipt of a zero signal at input 1 of block 58, i.e. when moving an electric iron.

 The output of the control unit of the triac 58 is connected to the control electrode and the cathode of the triac 60.

 The control unit of the triac 58 can be performed, for example, according to the circuit of Fig. 12 and contains a logic element consisting of an inverter 58.1 and an OR element 58.2, two transistors of different conductivity 58.3, 58.4, a differentiating circuit consisting of a capacitor 58.5 and a resistor 58.6.

Из диаграммы следует, что при нулевом сигнале на входе 1 выходной сигнал логического элемента (выход элемента 58.2) синфазен с сигналом на входе 2 и этим обеспечивается регулирование температуры сигналами, поступающими на вход 2 от нуль-оргна 59. При единичном сигнале на входе 1, т.е. при неподвижном электроутюге, на выходе логического элемента устанавливается нулевой сигнал независимо от сигналов на входе 2, который поступает на базы транзисторов 58.3, 58.4. Транзистор 58.3 включается, конденсатор 58.5 заряжается за время переходного процесса, и отключает управляющий электрод симистора 60, так как выход 1 блока 58 оказывается замкнутым через резистор 58.6 с выходом 2, т.е. с катодом симистора 60.The logic block has a truth diagram: In

From the diagram it follows that at a zero signal at input 1, the output signal of the logic element (output of element 58.2) is in phase with the signal at input 2, and this ensures temperature control by the signals received at input 2 from the zero-org 59. With a single signal at input 1, those. when the electric iron is stationary, a zero signal is set at the output of the logic element, regardless of the signals at input 2, which goes to the base of transistors 58.3, 58.4. The transistor 58.3 is turned on, the capacitor 58.5 is charged during the transient process, and turns off the control electrode of the triac 60, since the output 1 of block 58 is closed through a resistor 58.6 with output 2, i.e. with the cathode of triac 60.

 With a zero signal at input 1, i.e. with a moving electric iron, the pulses from input 2 coming from the zero-organ 59 with the key element 57 closed, the transistor 58.3 is turned on with a positive edge and the transistor 58.4 with a negative edge. The capacitor 58.5 differentiates the fronts of the output pulses of the transistors and generates at the output 1 relative to the output 2 of the block 58 short switching pulses of the triac 60.

 Triac 60 is connected by a cathode to one pole of a power source 61 (household electrical network) of an electric iron, and an anode with a first terminal of a heating element 3, the second terminal of which is connected through a thermal switch 62 to a second pole of a power source 61.

 Triac 60 is designed to turn on the voltage of the power source 61 to the heating element 3 when the temperature of the soleplate is lower than the set temperature and disconnect the voltage from the heating element 3 when the temperature of the soleplate exceeds the specified value or when the electric iron is stationary.

 The triac 60 is turned on by a pulse on the control electrode at the moments when the mains supply voltage passes through zero and the increasing voltage of the half-wave of the mains voltage along the anistor of the triac 60 for each half-period of the mains voltage (see Fig. 17, graph). The included triac 60 is a low current resistance, and the heating element 3 is connected to a power source and heats up (see Fig. 17, graph K, zone A). The off triac 60 is a large resistance and does not pass current, the heating element 3 is thus disconnected from the power source (see Fig. 17, graph K, zone B).

 Zero-organ 59 inputs connected to a power source 61, an output to the first input of the key element 57 and is designed to generate rectangular pulses with steep edges at the moments of transition of the alternating voltage of the power source 61 through the zero potential (see Fig. 17, graphs a, b) . On the fronts of these pulses, the control unit of the triac 58 generates short switching pulses of the triac 60 (see Fig, graph and).

The temperature switch 62 is designed to automatically break (open) the power circuit of the heating element 3 during emergency heating of the sole of the electric iron above a certain maximum permissible value, for example, 300 ^about C.

 The temperature switch 62 can be performed, for example, in accordance with A.C. USSR N 1597955.

 The temperature controller 66 is connected to the disk of the temperature controller 67, which sets the angle of rotation of the potentiometer 66, as in a conventional electric iron, for example, according to GOST 307-81E.

 The nozzle 68 is designed to spray water in front of the iron and has a shut-off valve when sucking water through a water supply pipe 69.

 The nozzle 68 can be performed, for example, by A. with. USSR N 1624080.

 The rear support 70 is designed to protect the circuit board 47 with electronic devices and for winding on its side surface of the power cord and is installed on the seats of the casing 4 and the housing 1 and is mounted with a screw 71.

 Electric iron with electronic control works as follows.

 Through the opening 38, water is poured into the water tank 5. In the initial position, by turning the button 41 to the stop, the steam valve is closed, while the needle cone 39 closes the hole 16 in the steam valve 7, and water does not enter the steam chamber 8. The power of the iron is turned on from the power source 61. On the disk of the setter temperature 67 set the temperature of the heating of the sole 2.

When the supply voltage is turned on in the vertical position of the electric iron, the motion and position sensor through the converter 49 generates a high potential, the switching pulse of which sets the integrator of the timing device 52 to its initial state with the output voltage U _beginning. (see Fig. 17, graph d), and the integrator begins to integrate the constant voltage of the setpoint supplied to its input 1 from the reference voltage source 51. At the same time, the outputs of the key elements 54.1 and 54.2 switch to the outputs of the comparators 53.2 and 53.4, at the outputs of which there are zero potentials . The audio signaling device 55 does not generate a signal, and the zero potential at the first input of block 58 ensures the operation of block 58 in the transmission mode of signals at input 2, i.e. in thermal control mode.

 A temperature sensor 65 measures the temperature of the soleplate. Since this temperature, when turned on, is lower than the set value on the set point 66, the bridge circuit of the electronic temperature controller 56 generates a signal including a comparator 56.5, the output of which has a high potential and includes a key element 57. The output pulses of the null-organ 59 go to the second input of the control unit of the triac 58, which along the edges of the input pulses generates short output pulses (see Fig. 17, graph I), which arrive at the control electrode of the triac 60, and open the triac along the anode-cathode circuit, the voltage drop across the triac 60 decreases is reduced to a value close to zero. Thus, the heating element 3 is connected to a power source 61 (see Fig. 17, graph k, zone A). The soleplate of the electric iron is heated until the resistance of the temperature sensor 65 increases so that the bridge circuit of the thermostat 56 balances and then changes the polarity of the input signal of the comparator 56.5, the output voltage of the comparator changes the polarity and turns off the key element 57. Pulses from the zero-organ 59 will stop arrive at input 2 of block 58, and block 58 will turn off the triac 60, while its resistance to the anode-cathode will become large, and the current through the heating elements 3 will stop flowing. The sole of the electric iron will cool. After some time, the temperature measured by the temperature sensor 65 will drop to a value at which the comparator of the temperature controller 56 again switches to a positive output signal and turns on the key element 57 again. The process of forming control pulses of the triac 60 and heating of the heating element 3 will begin.

 After heating the sole 2 by turning the control button 43, the steam valve 7 is opened, and water drops through the outlet 16 of the steam valve and through the through channel 14 drops to the bottom of the first camera 8, is sprayed and partially converted to steam. The steam-vapor mixture moves along the labyrinth of the first steam chamber, and water particles evaporate from heating about the ribs 11 when moving along the maze from the beginning to the exit of the first steam chamber 25. The steam-steam mixture, passing along the outer perimeter of the steam chamber 8 near the heating element 3, is significantly heated, and therefore intensive conversion of water particles into steam. The steam-water mixture, enveloping the protrusion 20 of the diaphragm 19, enters through the opening 21 into the second chamber 9, in which the final conversion of water particles into steam occurs, which through the outlet 30 enters the steam distributor 31 and through the outlet openings for the removal of steam 35 into the grooves 36 of the sole for moistening tissue.

 If it is necessary to moisten the fabric in front of the iron, press the control button 41, the rod of the pump 43 is lowered, the ball 46 closes the inlet of the pump, and water from the pump through the nozzle 68 is sprayed in front of the iron. The button 41 is released, the spring 45 lifts the rod of the pump 43 upward, and the water through the tube 69 is sucked into the pump housing. When working with the pump, the rate of vaporization does not change due to the free longitudinal movement of the rod 42 along the square slot of the needle of the steam valve 39. In this way, the spray pump is controlled independently and the water supply to the chamber is regulated. To ensure the desired temperature, turn the dial of thermostat 67.

 The electronic temperature controller 56 maintains a predetermined temperature when working with an electric iron and is blocked after the electric iron remains stationary for more than a predetermined time.

 When the electric iron moves, the voltage drops at the output of the signal converter of the sensor 49 from low to high and vice versa (see Fig. 17, graph c) set the integrator of the timing device 52 to the initial state (see Fig. 17, graph g), and its output the voltage during movement remains less than the setpoint voltage supplied to input 2 of comparator 53.1, comparator unit 53 from output 2 of unit 51. Comparator 53.1, as well as comparators 53.2.53.4 do not work, and no signals are generated at the inputs and outputs of key elements 54.1, 54.2 .

 With a stationary horizontal position of the electric iron, the sensor 48 through the converter 49 forms a low potential, which leaves the key elements 51.1, 54.2 in a normally closed state (see Fig. 17, graph c, after 3 pulses), i.e. their outputs are connected respectively to the outputs of the comparators 53.1, 53.2.

The timing device 52, integrating the voltage from the output 1 of the reference voltage source 51, after 30 s will generate a constant voltage at its output, which is equal to the setpoint voltage at the output 2 _{1 of the} source 51 (see Fig. 17, graph d, point a).

 The comparator 53.1 will work, and its high input potential (see Fig. 17, graph e) through a normally closed key element 54.1 will trigger an audible alarm 55, which will begin to generate intermittent warning signals (see Fig. 17, graphs g, h).

After 60 s, the timing device 52 will generate a constant voltage at its output, which will be equal to the setpoint voltage at the output 2 _of block ₂ 51 (see Fig. 17, graph g, point b), the comparator 53.2 will work (see Fig. 17, graph e) , and its output potential through a normally closed key element 54.2 will go to the input 1 of block 58 and will prevent the passage of pulses from input 2 from the zero-organ 59, the triac 60 will turn off and disconnect the heating element 3 from the power source 61 (see Fig. 17, graphs and, k, zone B).

 With a stationary vertical position of the electric iron, the sensor 48 through the converter 49 forms a high potential, which switches the key elements 54.1, 54.2 so that their outputs are connected respectively to the inputs of the comparators 53.3 and 53.4, and also blocks the operation of the comparators 53.1, 53.2 for comparison by the third inputs.

The timing device 52, integrating the voltage from the output 1 of the reference voltage source 51, in 5 minutes will generate a constant voltage at its output, which will be equal to the set voltage at the output 2 _{3 of} block 51. The comparator 53.3 will work, and its output potential through the closed contacts of the key element 54.1 will start the buzzer 55 to generate intermittent sound signals.

After 8 minutes, the timing device 52 will generate a constant voltage at its output, which will be equal to the set voltage at the output 2 _of block ₄ 51, the comparator 53.4 will operate, and through the closed contacts of the key element 54.2, a high potential from its output will go to input 1 of block 58 and similarly to the horizontal the position will disconnect the heating element 3 from the power source 61.

 When resuming the movement of the electric iron, the first pulse from the sensor 48 through the converter 49 will set the timing device 52 to its initial state (see Fig. 17, graph g, for the first pulse), the comparators of block 53 will switch to the zero output signal, the buzzer 55 will turn off, at the first the input of the control unit of the triac 58 will allow zero potential, and pulses from the output of the zero-organ 59 will begin to flow to the control electrode of the triac 60 in accordance with the control signal from the output of the electronic temperature controller 56 for adjusting the set temperature.
