Definitions

  • the invention relates to the field of steam irons with automatic cleaning and descaling / limescale removal system
  • a soleplate with a steam chamber with openings for the outlet of steam for ironing
  • a micropump with a first connection for the inlet of water into a water tank and a connection for the outlet of the water into the steam chamber
  • a heating system and a control device which is connected at least to the micropump and the heating system of the iron.
  • Steam irons including steam irons with a conventional electric micropump, equipped with a system for cleaning and descaling are known. These systems are usually operatively coupled directly to the ironing temperature setting switch and the steam switch (steam ironing switch for performing a normal steam ironing function) of the iron.
  • the user To perform the function of cleaning, limescale removal and descaling, the user must perform various operations. For example, the user must first turn the ironing temperature setting switch to a "cleaning and descaling position" which sets a cold or low temperature insufficient to produce steam so that the steam chamber is cold; after that, the user must press / activate the steam switch for a certain period of time.
  • the micropump is activated and a larger amount of water from the water tank is injected into the cold steam chamber; after that, the user must turn the ironing temperature setting switch to warm to quickly bring the cold water in the steam chamber to a boil and to produce a rapid temperature change where the steam and boiling water are the limescale on the walls of the steam chamber / Remove deposits that are passed through the openings of the steam chamber in the sole plate to the outside.
  • the conventional steam irons with a conventional cleaning and descaling system are relatively complicated and difficult to handle for the user.
  • the user must fully understand the various technical functions and switches of the iron, as he must activate various switches of the iron and perform the steps of cleaning and descaling in a particular order. Otherwise the cleaning and descaling does not work or does not work correctly.
  • the result of the cleaning and descaling operation largely depends on the manner in which each individual user uses his iron. For example, it is possible for the user not to set the temperature setting switch to a reasonably high temperature in order for the cold water to be heated quickly, or for the user not pressing the steam switch for a sufficient amount of time to get a sufficient amount of water into the steam chamber allow. Furthermore, other operator errors of the user may occur. Therefore, the results of cleaning and descaling may vary widely among different users, or the desired result may not even be achieved.
  • the object of the present invention is to provide a steam ironing / steam ironing apparatus having an improved and simpler but very effective cleaning and descaling function.
  • the iron further has a cleaning switch connected to the control device, which can be operated by the user to automatically activate the cleaning and descaling control program.
  • the steam iron / steam ironing device according to the invention has a completely automatic cleaning and descaling system: it only needs to be pressed once a switch, and the complete cleaning and descaling function is carried out completely and automatically.
  • control device preferably deactivates all other functions of the steam iron, for example the steam ironing function and / or the steam injection function and / or the spray functions, etc., in order to avoid any intervention and operator error on the part of the user.
  • the micro-pump has a second inlet port for introducing the descaling agent from a descaling tank, which improves the cleaning function of the lime.
  • the control device has safety means to prevent the user from undesirably activating the automatic cleaning and descaling function, the safety means being designed as a timer when the cleaning switch is pressed to start the cleaning process, for example after a press of 3 seconds.
  • Another implementation of the security means is to provide the cleaning switch with a rotatable cover which the user must open before the switch can be pushed, by means of spring means the cover returns to its closed position; or to equip the cleaning switch with a certain mechanical resistance, or to define a large distance, by which the switch must be pressed down.
  • the iron has at least one sensor connected to the control device to prevent erroneous operation of the system, the sensor being designed as a heat sensor to detect the temperature in the steam chamber, and if the steam chamber is above a predetermined temperature, the control device deactivates Cleaning and descaling, since the introduction of a larger amount of water into the warm steam chamber would cancel the desired result of the cleaning and / or produce an undesirable amount of steam.
  • the senor is designed as a Greedvant to determine the water level in the water tank and / or descaling tank, and if the water tank and / or descaling tank is below a predetermined level, the control device deactivates the cleaning and descaling system, to avoid that the micropump runs dry and that the heating device is activated.
  • This sensor is preferably connected to an audible and / or visual signal to inform the user of the empty tank (s).
  • the iron has a system for informing the user that the fully automatic cleaning and descaling function is in operation, for example by an optical signal, for example with an LED or a light indicator, or by an acoustic signal, for example with an electronic signal Warning sign or a speaker or by a combination of the above-mentioned signals.
  • an optical signal for example with an LED or a light indicator
  • an acoustic signal for example with an electronic signal Warning sign or a speaker or by a combination of the above-mentioned signals.
  • the same signal means can be used to indicate faulty operation of the system.
  • a "reminder" is issued to the user by, for example, an audible or visual signal.
  • the illustration 1 shows a schematic block diagram of the essential components of a steam iron according to a first embodiment of the invention.
  • the Figure 2 shows a schematic block diagram of the essential components of a steam iron according to a second embodiment of the invention.
  • the Figure 3 shows a schematic block diagram of the essential components of a steam iron according to a third embodiment of the invention.
  • the illustration 1 shows a schematic block diagram of the essential components of a steam iron according to a first very simple embodiment of the invention.
  • the iron has a sole plate 2 with a steam chamber 10, steam holes 4, and a heater H. Further, this is equipped with a micropump 8 having an inlet port E connected to a water tank 6 and an outlet port B connected to the water tank 6 Steam chamber is connected to introduce water into the steam chamber in a position P.
  • the heater H and the micropump 8 are both connected to a power source (not shown), respectively.
  • the iron also includes a steam switch BT1 for activating and deactivating a steam ironing function, a temperature setting switch BH for setting a predetermined ironing temperature of the heating device H and thus a predetermined temperature of the steam chamber. Furthermore, a BCL switch for descaling and cleaning is provided.
  • the switches BT1 and BCL and the setting switch BH are connected to a control device 18 via control lines L1, L3 and L2.
  • the control device 18 is connected via a control line LP to the micropump 8 and via a control line LH to the heating device H.
  • a user can Activate steam ironing functions by pressing and holding the steam switch BT1.
  • the micro-pump 8 is activated and water from the water tank 6 is injected in the position P in the steam chamber, where it is evaporated.
  • the steam leaves the steam chamber via the steam openings 4 in the sole plate 2.
  • the control device 18 activates the micropump 8 via the control line LP and keeps it activated for a first predetermined period of time, for example 5 to 8 seconds. In the present example, this is achieved by a timer T, which is integrated in the control device 18. In this way, a predetermined amount of water is injected into the cold steam chamber 10.
  • the controller 18 deactivates the micropump 8 and activates the heater H via the control line LH, preferably setting the heating temperature to the highest allowable or safe heating temperature.
  • the control device 18 keeps the heating device activated for a second predetermined period of time, for example between 10 and 30 seconds. This is done by means of the timer T. In this way, the steam chamber is heated rapidly to a predetermined cooking temperature and the originally cold water in the steam chamber is brought to a boil quickly. All this leads to a rapid change in temperature in the steam chamber and the boiling water and steam dissolve the limescale / deposits from the steam chamber, which are passed through the openings 4 in the sole plate 2 to the outside. After completion of the second predetermined time interval, the control device 18 deactivates the heating device H.
  • the operation of the BCL switch is mainly used to trigger the fully automatic cleaning and descaling, that is, to enter a kind of start signal in the control device 18. Therefore, the BCL switch and its connection function should preferably be interpreted as meaning that, even if the user holds down the BCL switch (or presses it again after the first press), it will not affect the process or will cause the process to be canceled.
  • the Figure 2 shows a schematic block diagram of the essential components of a steam iron according to a second embodiment of the invention. In the following, only the differences from the first embodiment according to FIG illustration 1 explained.
  • the micropump 8 of this version has at least two inlet ports E1 and E2.
  • the first inlet port E1 is linked or connected to the water tank 6a, while the second inlet port E2 is linked or connected to a decalcifier tank 6b.
  • the tanks 6a, 6b can be designed as individual tanks or integrated in a common tank unit with different compartments.
  • an inlet valve (not shown) may be arranged adjacent to the inlet port E2; This said inlet valve opens only when the suction level of the micropump 8 during the fully automatic cleaning and descaling exceeds a certain threshold, as is the case here, or if so provided.
  • the inlet valve may be a control valve (not shown) that may be actively opened and closed based on a control signal, for example from the controller 18.
  • said control valve could be opened to allow the de-scaling agent of the tank 6b to flow inside the micropump 8 and to be injected into the steam chamber 10 together with the water of the tank 6a.
  • the micropump 8 itself could be equipped with a controllable multidirectional inlet valve, as indicated by the symbol of reference 8a on FIG Figure 2 is pictured.
  • This multidirectional intake valve 8a comprises (or is connected to) the intake ports E1 and E2 and is controllable by means of a control signal of the control device 18. In this way, it is possible to close the inlet port E2 during the normal steam ironing functions (or other ironing functions) and to open the inlet port E2 during the automatic cleaning and descaling operation to allow the de-scaling agent of the tank 6b to enter the interior of the micropump 8 flows and is injected into the steam chamber 10 together with the water of the tank 6a.
  • the micropump 8 is preferably an adjustable micropump whose pumping power or pumping current can be regulated.
  • the reason for this is the fact that during the normal steam ironing operations usually a smaller amount of water is required to produce the steam, whereas in the fully automatic cleaning and descaling process, a larger amount of water / liquid has to be injected into the steam chamber for a relatively short period of time.
  • the controller 18 may include a "post-purge” program and / or be configured to control a "post-purge operation,” for example, to remove residues of the (corrosive) descaling agent from the steam chamber 10 to remove.
  • the automatic "post-purge" routine may be performed via the controller 18 during which the inlet port E2 is closed, the inlet port E1 is open, and the micropump 8 is activated and remains activated for a predetermined period of time (for example, during FIG seconds). In this way, simply water (hot, still warm or even cold) is injected from the tank 6a into the steam chamber 10 to remove the residue of descaling agent (which could be corrosive depending on the type of clothing) from the steam chamber 10.
  • the controller 18 deactivates the micropump 8 and preferably closes all inlet ports E1, E2, thereby performing an anti-drip function.
  • the timer T and / or the controller 18 may also be configured as a mechanical device as far as the operation of the micropump 8 (and / or its multidirectional intake valve) for the fully automatic cleaning and descaling operation is concerned.
  • This mechanical device may be a rotary switch that can be rotated starting from a neutral position against the biasing forces of a tensioning element to a "prepared" position in which it opens the inlet ports E1 and E2 and activates the micropump 8. From this "prepared” position, the rotary switch is slowly returned to its neutral position due to the biasing forces of the tensioning element, deactivating the micropump 8 and closing the inlet ports E1 and E2.
  • the slow reset can be achieved, for example, by providing a damper or mechanical resistance in the path of the rotary switch. This will ensure that the rotary switch takes a certain amount of time to return to its neutral position. In this way, the above-described "predetermined period of time" is achieved or defined in order to suitably put the iron according to the invention back into operation during the cleaning and descaling operation.
  • the fully automatic cleaning and descaling system according to this invention can be used in a steam iron or in a steam ironing device according to the patent application ES_ 2336519_A1 be included as on the Figure 3 you can see.
  • This embodiment is similar to that on the illustration 1 However, it has a micropump 8 with a controllable multidirectional exhaust valve 12 and a steam pulse switch BT2.
  • This version can also be completed with a sputtering system and a sputter switch, which is also connected or linked to the control device 18 and the micropump 8.
