Definitions
- the present invention relates to apparatus and installations washing laundry carts or hospitals, or large bins, requiring satisfactory disinfection.
- Carts or mobile bins of laundry rooms or hospitals are used for transporting various objects such as linen, meal trays, medicines.
- the transported objects usually contain germs that tend to settle on carts or mobile bins, which germs can then develop and / or spread to other objects transported later by the same carriages. This results in a risk of spreading infections by bacteria or fungi.
- the enclosure includes horizontally movable wash ramps or vertically along at least one side of the washing chamber to spray a washing liquid to the trolley or carts in a sweeping motion.
- a wash cycle is followed by hot air drying where circulating heated air in the enclosure.
- the problem proposed by the present invention is to design a new structure of washing machine of trolleys and mobile bins that allows to ensure perfect drying in a reduced cycle time, thus allowing to increase the washing rates.
- the object of the invention is in particular to ensure a very efficient drying in the interstices of carts or mobile bins to be washed, in order to avoid any development of germs and fungi in these interstices because of the possible presence of moisture.
- the aim of the invention is to achieve such efficient drying without increasing excessively the temperature of the trolley or mobile container at the end of the drying cycle, to allow immediate gripping of the trolley or mobile container as soon as the end of drying.
- drying is particularly fast and efficient, and the risks of stagnation are eliminated moisture in the interstices of a trolley or mobile container to be washed.
- dehumidification allows fast drying without having to overheat the drying air.
- the heating elements of the main shuttle heat the drying air at a temperature between 40 ° C and 50 ° C, advantageously of the order of 45 ° C. It is thus possible to hold the trolley at the immediately after drying, without waiting for its cooling.
- the main shuttle is disposed along a side wall of the washing chamber and further carries a or several washing ramps adapted to project jets of washing liquid transversely in the washing chamber below the pipes producing the transverse unidirectional air gap.
- a more efficient washing is obtained by providing a secondary shuttle opposite to the main shuttle, movable vertically in front of the shuttle main and carrying one or more wash ramps.
- the central dehumidification can advantageously include a second ventilation means for selectively sucking air out of the enclosure wash and pass it through an evaporator that cools the air and condenses its moisture, then through a condenser and through a heated battery that heat the air, then return it to the washing chamber.
- a second ventilation means for selectively sucking air out of the enclosure wash and pass it through an evaporator that cools the air and condenses its moisture, then through a condenser and through a heated battery that heat the air, then return it to the washing chamber.
- the dehumidification plant comprises a component which, in a first washing position, selectively selects the extracted air of the washing chamber to send it to the outside atmosphere during the steps washing, and which, in a second drying position, selectively needle the air extracted from the washing chamber to return to the washing chamber in recycling after passing through the evaporator, condenser and battery during the drying stages.
- the entry flap in first position of washing takes outside air to send it to the washing chamber through the evaporator, the condenser and the heating battery which is then inactive.
- the main shuttle and the shuttle secondary are driven each in vertical movement by a respective winch and a respective traction cable, with a tension sensor of the traction cable which provides an alarm signal to interrupt the rotation of the winch in case of detecting a voltage greater than a high threshold determined or less than one low threshold determined.
- the washing machine trolleys and bins comprises a closed washing chamber 1, of parallelepipedic general shape, limited by two lateral faces 2 and 3, one face front end 4, an anterior front face opposite to the rear end face 4, a floor 5 and a ceiling 6.

- the first two washing ramps 18 and 19 are carried by a main shuttle 22, mounted vertically movable near the first side wall 2 of the enclosure 1.
- the main shuttle 22 is guided in its vertical movement along vertical guides 23 integral with the walls of the enclosure 1, and is driven by a first traction cable 24 solicited by a first winch top 25.
- the other two washing ramps 20 and 21 are carried by a shuttle secondary 26 which is itself in vertical displacement along second vertical guides 27 and which is driven by a second traction cable 28 itself biased by a second upper winch 29.
- the main shuttle 22 is box-shaped, with an air inlet 22c side opposite the side wall 2, and with a slot-shaped air outlet 22e on the opposite side.
- the main shuttle 22 contains a first ventilation means 22a, consisting of a turbine with axial suction and radial discharge, driven by a 22b electric motor.
- the turbine 22a draws air through the axial inlet 22c at adjacent to the side wall 2, and delivers air through a radial passage 22d towards the lower compartment of the box with the 22nd lateral outlet in the form of a slot at the end of a progressive dihedral narrowing zone 22f.
- the box thus formed constitutes a suitable guide pipe.
- a heating element 22g is disposed for example downstream of the turbine 22a. In this way, the shuttle 22, by rotation of the motor 22b and the turbine 22a, can produce a hot air flow in the form of a horizontal blade directed towards the side wall opposite 3 that is to say towards the center of the enclosure 1.
- the hot air blade coming out of the main shuttle 22 is a unidirectional air knife which causes mechanically drops of liquid present on the carriage 7 or mobile container when drying steps.
- the chamber 1 is associated with a dehumidification unit 30, adapted to suck air from the enclosure 1, to dry the sucked air, for the reheat and return it to enclosure 1 in a separate circulation of the air flow produced by the main shuttle 22 during the steps of drying.
