Definitions

  • the present invention relates to an appliance having a vessel in which water is boiled and more particularly relates to an appliance with means for removing the scale formed in the tank.
  • the driven scale may close a control solenoid valve or be deposited on the laundry leaving unpleasant traces.
  • Tartar accumulated in the tank must be removed periodically to avoid these disadvantages. For example, it is recommended to intervene every ten uses to carry out this cleaning on an ironing apparatus used normally.
  • an object of the present invention is to provide an appliance having a vessel in which water is boiled and comprising a device for easily removing the scale formed by the boiling of the water in the tank .
  • Another object of the invention is to propose a means to evacuate calculus allowing the user to better visualize the quantity of tartar removed.
  • the subject of the invention is an appliance comprising a vessel in which water is boiled and means for evacuating the scale formed in the tank, characterized in that the means for evacuating the scale comprise a scale collection container disposed near the bottom of the tank, the container being removable by an opening of the tank.
  • the container is secured to a stopper closing the opening of the vessel through which the container can be extracted.
  • the opening is disposed at the top or at the bottom of the tank.
  • the opening is disposed on a side wall of the tank, the container having an elongated shape that can be extracted from the tank through the orifice.
  • the opening is disposed near the bottom of the tank and constitutes a drain orifice.
  • the container is made of a flexible material.
  • Such a feature has the advantage of allowing easy cleaning of the container.
  • the container is made of a rigid material.
  • spring means apply the container against the bottom of the tank.
  • the tank has deflecting walls which are arranged at the edge of the container when the latter is placed in the tank.
  • Such a characteristic makes it possible to generate a zone of calm above the tartar recovery container, during the boiling of the water in the tank, so that that tartar particles stirred by boiling are deposited by gravity in the container;
  • said deflecting walls are inclined and converge towards the container.
  • the deflecting walls cover between 20% and 50% of the bottom surface of the tank.
  • the deflecting walls are attached to the bottom of the tank.
  • the deflecting walls are stamped in the bottom of the tank.
  • the apparatus is an ironing apparatus, the vat for the production of steam being connected to an iron or a steam brush.
  • the figure 1 represents a steam generator under pressure for an ironing apparatus comprising a tank 1 conventionally comprising heating means for the production of steam under a maximum pressure of the order of 4 or 5 bars.
  • This tank consists of a lower shell 1A and an upper shell 1B, preferably stainless steel, joined to one another by welding.
  • the upper shell 1 B of the tank has a lateral outlet port 10 of steam on which is fixed a solenoid valve, not shown in the figure, intended to be connected to an iron by a cord, the iron having a control button for controlling the opening of the solenoid valve to control the sending of steam to the iron.
  • the lower shell 1 A of the tank has a tubular connection 2, screwed into a lateral orifice of the tank 1, having a drain orifice 2A, visible on the figure 3 , closed by a plug 3.
  • the connection 2 comprises a water supply 2B connected by a pipe to a pump fed by a reservoir, not shown in the figures, and for maintaining a water level in the tank 1 regulated between a minimum level and a maximum level.
  • the vessel 1 contains a device for collecting scale comprising a collecting container 4, visible on the figure 2 .
  • the recovery vessel 2 is preferably associated with a deflector 5 deflecting the bubbles created by the boiling of the water and away from the area above the tarsal recovery vessel 4 to create a zone of calm above the recovery vessel 4 favoring scale deposition by gravity.
  • the deflector 5 advantageously comprises two flat deflecting walls 5B disposed on either side of a central channel 5A converging towards the latter, the central channel 5A being disposed in the axis of the drain orifice 2A to form a longitudinal housing for the recovery container 4.
  • the deflector consists of a stamped stainless steel sheet, welded to the bottom of the vessel 1.
  • the deflecting walls 5B cover on the order of 25% of the bottom surface of the tank 1 and the upper end of the deflecting walls is at least 5 mm below the water level in the tank 1 under normal operating conditions of the steam generator.
  • the deflecting walls 5B support a spring piece 9 having a blade 9A provided with a curved end touching the top of the channel 5A and for exerting pressure on the collecting container 4 to bring it to the bottom of the the gutter 5A when introduced into the tank 1 through the drain port 2A.
  • the recovery container 4 has the shape of a cylindrical rod that can be inserted into the drain hole 2A of the tank.
  • This rod is preferably made of a flexible material, such as an EPDM material (Ethylene Propylene Diene Monomer) or a silicone, and has a truncated upper face defining a flattened area where a number of cavities 4A for receiving scale, with a capacity of order of 1 cm 3 , separated from each other by partitions.
  • EPDM material Ethylene Propylene Diene Monomer
  • silicone silicone
  • the container 4 made of flexible material, is connected to a rigid element 6 which is inserted into the connector 2 when the container 4 is introduced into the tank 1, the rigid element 6 comprising a groove 6A cooperating with a polarizing element 7 by the connector 2 to orient the rod 4 so that the cavities 4A are necessarily facing upwards when the collecting container 4 is introduced through the drain port 2A.
  • the rigid element 6 is preferably integral with the plug 3 closing the drain port 2A, the plug 3 being in this case rotatably mounted relative to the rigid element 6 so as to be screwed or unscrewed on a thread surrounding the drain hole 2A without rotating the collecting container 4 to harvest the tartar.
  • the leaf spring 9A when the collecting container 4 is introduced into the tank 1 through the drain orifice 2A, the leaf spring 9A produces a vertical force on the upper face of the flexible container 4 so that the latter is applied against the bottom of the tank 1 inside the gutter 5A over most of its length.
  • the start of the heating means of the tank here constituted by a heating resistor 8 disposed under the tank 1, causes the heating of the water until boiling. .
  • This boiling material izes by the formation of vapor bubbles at the bottom of the tank 1 which rise towards the surface of the water, the bubbles generated in the area under the deflector 5 being deflected by the deflecting walls 5B and that this is illustrated by the arrows on the figure 6 .
  • the user can then perfectly visualize the amount of tartar he has extracted from the tank of the device and measure the interest of such an operation for the proper operation of the device. It can also deduce, from the quantity of tartar extracted from the tank, whether it is preferable to increase or reduce the frequency of such a scale removal operation.
  • FIGS. 7 and 8 illustrate an alternative embodiment of the tartar recovery container equipping a household appliance according to the invention.
  • the device for collecting the scale comprises a tartar recovery vessel 40 having the shape of an elongated bowl obtained for example by stamping a sheet of stainless steel.
  • the recovery container 40 has a length of the order of 12 cm, a width of about 1 cm and a height of about 8 mm to harvest a volume of tartar of the order of 5 cm 3 .
  • This collecting container 40 is welded to the end of a bent spring rod 90, the other end of the rod 90 being connected to a plug 30 which is screwed onto the connector 2, the plug 30 being able to rotate freely relative to the rod 90 to allow screwing or unscrewing of the plug 30 without rotating the rod 90 and thus the recovery container 40.
  • such a recovery vessel 40 may be introduced into a vessel 1 for steam generation similar to that described above in connection with the Figures 1 to 6 , but not having a spring piece 9.
  • the return force applying the recovery container 40 against the bottom of the tank 1 is provided by the spring rod 90 bent interposed between the plug 30 and the recovery container 40.
  • Such an alternative embodiment therefore has the advantage of allowing a simpler assembly that does not require a spring piece 9 on the deflector blades 5B.
  • the emptying hole of the tank may be disposed at the wall defining the bottom of the tank and be closed by a plug having a diameter and a sufficient depth to form a tartar recovery container .
  • the bottom of the tank will then advantageously receive, around this drain orifice, deflector means constituted for example by a frustoconical wall converging towards the orifice.
  • the vessel for collecting scale can be introduced and extracted into the tank through an orifice located on the upper face of the tank, such as a filling orifice of the tank.
  • the container will then be advantageously formed by a cup connected to the closure cap of the filling orifice by a rod whose length is substantially equal to the height of the tank so that the cup is close to the bottom of the tank when the cap closes the filling port.
  • the deflecting walls may be stamped directly into the wall forming the bottom of the tank instead of being reported by welding.
