Washer machine

Abstract

A washer machine for objects, comprises an inner washing chamber, accessed through an aperture associated with a closing device comprising a door cooperating with peripheral edges that delimit said aperture. The closing device comprises a plurality of pneumatic gaskets, each of which is connected to its own pressurized pneumatic means, operatively independent of each other and able to introduce a pressurized fluid inside the respective gaskets, selectively determining a dilated operating condition thereof to achieve the hydraulic seal.

1 . A washer machine for objects, comprising an inner washing chamber, accessed through at least one aperture delimited by peripheral edges, and a closing device comprising at least one door for said aperture, wherein said closing device comprises:
 a plurality of pneumatic gaskets disposed adjacent and in series with respect to each other, inside mating seatings to achieve a hydraulic seal between said door and the peripheral edges of said aperture,   a plurality of pressurized pneumatic devices operatively independent from each other and configured to introduce a fluid under pressure inside the gaskets, selectively determining a dilated operating condition thereof in order to achieve the hydraulic seal, in which each of said gaskets is connected to its own and corresponding one of said pressurized pneumatic devices.   
     
     
         2 . The washer machine as in  claim 1 , comprising at least one containing wall disposed between adjacent gaskets. 
     
     
         3 . The washer machine as in  claim 2 , wherein said at least one containing wall is continuous and disposed between said gaskets, completely following the whole development or profile of the gaskets, to function as a physical barrier between them. 
     
     
         4 . The washer machine as in  claim 1 , wherein the gaskets are mounted on the door. 
     
     
         5 . The washer machine as in  claim 4 , wherein the seatings are made on the door. 
     
     
         6 . The washer machine as in  claim 1 , wherein the gaskets are mounted along the peripheral edges of the aperture. 
     
     
         7 . The washer machine as in  claim 6 , wherein the seatings are made along the peripheral edges of the aperture. 
     
     
         8 . The washer machine as in  claim 1 , comprising one or more gaskets mounted on the door and one or more gaskets mounted along the peripheral edges of the aperture. 
     
     
         9 . The washer machine as in  claim 1 , wherein at least one of the gaskets is provided with one or more friction elements protruding from its surface. 
     
     
         10 . The washer machine as in  claim 1 , wherein the pressurized pneumatic devices are connected to the corresponding gaskets by means of flexible connection pipes. 
     
     
         11 . The washer machine as in  claim 1 , wherein the gaskets are made of elastomeric material. 
     
     
         12 . The washer machine as in  claim 1 , wherein the seatings are made as grooves, in particular with concave cross section. 
     
     
         13 . The washer machine as in  claim 1 , wherein the gaskets and the seatings are reciprocally sized so that, in the dilated operating condition, the gaskets protrude from the seatings. 
     
     
         14 . The washer machine as in  claim 1 , configured for use in heat disinfecting washing and/or sterilization of objects. 
     
     
         15 . The A method to control the safe closing of a washer machine for objects as in  claim 1 , providing the verification of the effectiveness of the gaskets by detecting the pressure of the compressed fluid present in the gaskets and if a signal generated by said detection, and interpreted by a system controller, corresponds to a pressure value outside a predefined operating pressure range, the system controller transmits an automatic warning signal or alarm. 
     
     
         16 . The washer machine as in  claim 1 , comprising a system controller and a computer program memorizable in a memory readable by a computer which contains the instructions which, when executed by the system controller, determine the execution of a method to control the safe closing of a washer machine for objects as in  claim 1 , wherein the method comprises providing the verification of the effectiveness of the gaskets by detecting the pressure of the compressed fluid present in the gaskets and if a signal generated by said detection, and interpreted by a system controller, corresponds to a pressure value outside a predefined operating pressure range, the system controller transmits an automatic warning signal or alarm.
