Definitions

  • the present invention relates to a wet and dry vacuum cleaner.
  • Vacuum cleaners are known which can be used to aspirate both solid substances, such as dust or solid matter in general, and liquids.
  • vacuum cleaners are generally constituted by a body (typically associated with movement means, such as ground contact wheels), which forms the compartment for containing the aspirated substances (solid and liquid ones), and by an upper closure cover.
  • the suction motor (electric motor with suction impeller) is generally associated with the upper closure cover; this is done in order to reduce, in the liquid suction function, the problems of isolating the motor from water.
  • a wet vacuum cleaner is also known and disclosed for example in Italian patent application PD2004A000088, filed by this same Applicant, which uses a suction motor, which is arranged on the bottom of the body and is functionally connected to the compartment for containing liquids (or, optionally, solids) by means of a U-shaped duct, which ends with an opening that faces downward and can be closed by a float.
  • the aim of the present invention is to provide a wet and dry vacuum cleaner that solves the problems noted in known types.
  • an obj ect of the present invention is to provide a wet and dry vacuum cleaner that avoids mixing aspirated liquids with solid objects.
  • Another object of the present invention is to provide a wet and dry vacuum cleaner that does not require troublesome readaptations and inconvenient cleaning operations to use it as a wet vacuum cleaner or as a dry vacuum cleaner.
  • Another object of the present invention is to provide a wet and dry vacuum cleaner that can be manufactured with known systems and technologies.
  • a wet and dry vacuum cleaner which comprises a body with which a suction motor is associated, said motor being functionally connected to the inside of said body, said body having an outward suction intake, characterized in that inside said body there are at least two mutually separate collection compartments, of which at least one is designed for collecting liquids, said suction motor being functionally connected to both of said at least two compartments, said suction intake being associated with switchable means for connection to a single compartment of said at least two compartments.
  • a first embodiment of a vacuum cleaner according to the invention is generally designated by the reference numeral 10.
  • the vacuum cleaner 10 comprises a body 11, with which a suction motor 12 (understood as an electric motor with a suction impeller) is associated, said motor being functionally connected to the inside of the body 11.
  • a suction motor 12 understood as an electric motor with a suction impeller
  • the suction motor 12 is arranged on the bottom 14 of the body 11, as described in greater detail hereinafter.
  • a partition 16 Inside the body 11 there are, in this embodiment, two collection compartments, which are mutually separated by a partition 16: respectively, a first compartment 15a for containing liquids and a second compartment 15b for containing solids.
  • the body 11 has an outward suction intake 17, which is associated with switchable means 18 for connection to a single compartment 15a or 15b alternatively.
  • the switchable connection means 18 comprise a connector 19, for example a T-shaped connector, for connecting the two compartments 15a and 15b and the outside.
  • a coupling 20 is inserted rotatably in the connector 19 and is provided with an opening 22 for connection to a suction hose 23, which can be maneuvered by a user, and a lateral opening 25, which is connected, depending on its rotational arrangement in the connector 19, alternatively with only one of the two compartments 15a or 15b.
  • the suction motor 12 is functionally connected at the intake simultaneously to both compartments 15a and 15b.
  • the suction motor is arranged on the bottom 14 of the body 11.
  • a vacuum cleaner with the motor on the bottom of the body is disclosed for example in Italian patent application PD2004A000088 filed by this same Applicant.
  • the suction motor is accommodated in a box-like chamber 26, which straddles both compartments 15a and 15b.
  • the parts of the box-like chamber 26, respectively the first part 26a and the second part 26b, which are located in the first compartment 15a and in the second compartment 15b, have suction paths, respectively a first suction path 27a and second suction paths 27b, for connection between the suction motor 12 and the compartments 15a and 15b.
  • the first suction path 27a comprises a duct 28, which extends upward from the box-like chamber 26 and ends with an end portion 29 that has an inlet 30 that faces downward.
  • the inlet 30 can be closed by a float 31, which is arranged on a vertical guide 32, substantially at the vertical of the inlet 30.
  • the float 31 is laterally larger than the inlet 30, so as to cover it completely and hermetically if it is moved so as to close it.
  • the second suction paths 27b are constituted by a grille 33, which is formed monolithically with the box-like chamber 26.
  • box-like chamber 26 is provided with outward vents (not shown in the figures) to allow the suction of the suction motor 12.
  • the coupling 20 is turned, connecting the lateral opening 25 to the first compartment 15a or to the second compartment 15b.
  • a second embodiment of a vacuum cleaner according to the invention is generally designated by the reference numeral 100 and is shown in Figures 3 and 4.
  • the vacuum cleaner 100 comprises a body 111, with which a suction motor 112 (understood as an electric motor with a suction impeller) is associated and is functionally connected to the inside of the body 111.
  • a suction motor 112 understood as an electric motor with a suction impeller
  • the suction motor 112 is integrated, in a known manner, on the cover 114 of the body 111.
  • a partition 116 inside the body 111 there are two collection compartments, which are mutually separated by a partition 116, respectively a first compartment 115a for containing liquids and a second compartment 115b for containing solids.
  • the body 111 is provided with an outward suction intake 117, which is associated with switchable means 118 for connection to a single compartment 115a or 115b alternatively.
  • the switchable connection means 118 comprise a connector 119, for example a T-shaped connector, for connection between the two compartments 115a and 115b and the outside.
  • a coupling 120 is inserted rotatably in the connector 119 and is provided with an opening 122 for connection to a suction hose 123 that can be maneuvered by a user and a lateral opening 125, which is connected, depending on its rotational arrangement in the connector 119, alternatively to only one of the two compartments 115a or 115b.
  • the suction motor 112 is functionally connected for suction simultaneously to both compartments 115a and 115b.
  • the suction motor straddles both compartments 15a and 15b and has independent suction paths, not shown in the figures.
  • a grille-like covering is associated with the suction motor 12 and is divided by the wall 116 respectively into a first grille-like covering portion 126a, in the first compartment 115a, and a second grille-like covering portion 126b, in the second compartment 115b, which prevents large objects from obstructing said independent suction paths.
  • the present invention provides a wet and dry vacuum cleaner that allows to aspirate both liquid and solid substances without performing troublesome readaptations or inconvenient cleanings of said vacuum cleaner.
  • the suction motor is functionally connected to each compartment in a differentiated manner, in order to be able to aspirate liquids on one side and dust on the other side.
  • the materials employed may be any according to requirements and to the state of the art.
