Definitions

  • the present invention relates to an improved delivering-dispensing assembly for washing machines.
  • the aim of the present invention is to further improve the washing efficiency of a washing machine, starting from the basic idea that this washing efficiency is directly proportional to the amount of detersive which is post-added as the washing water has obtained a desired or set temperature.
  • a delivering-dispensing assembly which allows to better exploit the detersive, both by reducing the loss deriving from that portion of detersive which in actual practice is not dissolved in the cold washing water, and by increasing the efficiency of said detersive, which is caused to be dissolved in water which has already been brought to a set temperature.
  • a further object of the present invention is to provide a delivering-dispending assembly which is adapted to efficiently control all of the washing steps and, moreover, which can be easily fitted to the properties of several washing products like those which are conventionally used in 'washing machines.
  • an improved delivering-dispensing assembly for washing machines comprising a drawer vessel, divided into five compartmens, there-above there are arranged water supply means for supplying washing water, characterized in that said compartments comprise an intermediate loading compartment, for introducing into the washing machine a first amount of water, and an over-washing compartment for introducing into said washing machine a second amount of water and the full dose of a washing detersive, the supplying of said second amount of water and full dose of detersive being performed after the achievement by the first amount of water of a preset temperature.
  • the improved construction delivering-dispensing assembly for washing machines comprises a drawer vessel, generally indicated at the reference number 1, which is provided with five compartments, respectively indicated at 2, 3, 4, 5 and 6.
  • water supplying means for introducing into the washing machine the washing water, which water supply means have been generally indicated at the reference number 10.
  • the compartment 2 of the drawer vessel is a pre-washing compartment, which allows the user to perform a conventional type of prewashing, by an automatic programmed pre-washing step.
  • the pre-washing can be of an autonomous type, of a delayed switch-on type, or it can be fully omitted, with a start of the washing cycle in a subsequent step.
  • an over-washing compartment 4 thereinto there is introduced a second amount of water, so as to reach the over-washing level L and thereinto there is further added, as it will be disclosed in a more detailed way hereinafter, the full dose of detersive.
  • the compartment 5 is the compartment provided for performing the conventional introducing of the bleaching material, whereas the compartment 6 is provided for supplying possible additives such as softening substances and the like.
  • the over-washing step which is performed by supplying the second amount of water through the over-washing compartment, provides for the use of the full loaded detersive dose, with the water bath brought to the preset temperature.
  • This system reduces, and in actual practice overcomes,the settling loss of the detersive and the so-called chemical loss, related to a lack of oxygen development, by the oxidizing substances, at the start of each cycle and in all of the cycles performed at low temperature.
  • the sodium perborate provides its full oxidizing action at temperatures greater than 60°C, which are not present in the first portion of the washing cycles.
  • the user has the possibility of performing a conventional washing cycle, which comprises pre-washing, washing, bleaching steps, as well as an additive addition step.
  • the fact is to be pointed out that by supplying water in two distinct steps, that is with a starting minimum water loading, for softening the linen, and a second step, by supplying the full dose of detersive, with the washing bath already brought to a preset temperature, it is possible to better exploit the characteristics and doses of detersive, thereby providing better washing results, together with a reduction of the detersive consume.
  • the supplying of a minimum level of water inside the washing basin allows to quickly heat said water, with a consequent reduction of the electrical power consume.
  • the disclosed construction affords the possibility of using softening or sweetening products exclusively for the amount of water which is actually necessary for the washing operation, and, moreover, it is possible to use either liquid or powder detersives, as well as detersives strengthened by oxidizing or calcium removing substances.
  • the used materials provided that they are compatible with the intended use, as well as the contingent size and shape, can be any according to requirements.
