Definitions

  • the upper liquid level and the lower liquid level are selected separately. Wherein preferably the separate selection occurs sequentially. In advantageous manner this separate selection process further improves the intuitively of the design.
  • the intake 106 may be provided around the bottom of the pump 100 while the output 108 may be behind the main compartment 104 as per application or implementation requirements.
  • the submersible pump 100 includes one or more sensors 112 (generally, one or more stationary and touch sensitive sensors 112).
  • the one or more stationary and touch sensitive sensors 112 which configure the submersible pump 100 to operate within a threshold operating level 114.
  • the one or more sensors 112 may be present between a top 122 and a bottom 124 of the pump body 102 and are arranged in a direction substantially normal to the water level.
  • the submersible pump 100 has a preset gesture 140 for setting a desired liquid level (i.e. the threshold operating level 114).

Abstract

L'invention concerne une pompe submersible (100), laquelle pompe comprend un corps de pompe (102). La pompe submersible (100) forme un compartiment principal (104) ayant une admission (106) et une sortie (108) pour un liquide (110). Le corps de pompe (102) est apte à la submersion dans un corps de liquide (110) dont le niveau doit être contrôlé. Le ou les capteurs (112) configurés dans la pompe submersible (100) fonctionnent à l'intérieur d'un niveau de fonctionnement de seuil (114). Le niveau de fonctionnement de seuil (114) se trouve entre un niveau de liquide inférieur (116) et un niveau de liquide supérieur (118) établis sur la base d'un toucher d'utilisateur sur le ou les capteurs (112). La pompe submersible (100) est caractérisée en ce que le ou les capteurs de la pompe sont des capteurs tactiles stationnaires. Le toucher de l'utilisateur comprend un geste pré-établi (140) pour établir le niveau de liquide souhaité, soit par effleurement soit par toucher sur le ou les capteurs (112).
